Complete working example in Kotlin, I have replaced my API keys with 1111...

        val apiService = API.getInstance().retrofit.create(MyApiEndpointInterface::class.java)
        val params = HashMap<String, String>()
        params["q"] =  "munich,de"
        params["APPID"] = "11111111111111111"

        val call = apiService.getWeather(params)

        call.enqueue(object : Callback<WeatherResponse> {
            override fun onFailure(call: Call<WeatherResponse>?, t: Throwable?) {
                Log.e("Error:::","Error "+t!!.message)
            }

            override fun onResponse(call: Call<WeatherResponse>?, response: Response<WeatherResponse>?) {
                if (response != null && response.isSuccessful && response.body() != null) {
                    Log.e("SUCCESS:::","Response "+ response.body()!!.main.temp)

                    temperature.setText(""+ response.body()!!.main.temp)

                }
            }

        })

If you use several projects on a solution, and call method in one project to another project, make sure that all projects (called project and caller project) use the unique 'System.Net.Http' version.

I had this exact same problem with a site (Kentico CMS), starting development in 4.5, finding out the production server only supports 4.0, tried going back down to target framework of 4.0. Compiling the other posts in this thread (specifically changing target framework to .Net 4 and .Net 4.5 still being referenced). I searched through my solution and found that a handful of the NuGet packages were still using libraries with targetFramework="net45".

packages.config (before):
<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="AutoMapper" version="3.1.0" targetFramework="net45" />
  <package id="EntityFramework" version="5.0.0" targetFramework="net45" />
  <package id="Microsoft.AspNet.WebApi.Client" version="5.0.0" targetFramework="net45" />
  <package id="Newtonsoft.Json" version="4.5.11" targetFramework="net45" />
</packages>

I changed the projects target framework back to 4.5, removed all NuGet libraries, went back down to 4.0 and re-added the libraries (had to use some previous versions that were not dependent on 4.5).

packages.config (after):
<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="AutoMapper" version="3.1.1" targetFramework="net40" />
  <package id="EntityFramework" version="6.0.2" targetFramework="net40" />
  <package id="Microsoft.AspNet.WebApi.Client" version="4.0.30506.0" targetFramework="net40" />
  <package id="Microsoft.Net.Http" version="2.0.20710.0" targetFramework="net40" />
  <package id="Newtonsoft.Json" version="4.5.11" targetFramework="net40" />
</packages>

This could happen if you are using reflection to GetProperty of an object which is null.

Still seeing this error in 2020. As was stated by stt106 above, there are many, many possible causes. In my case, it was during automated insertion of data into a worksheet, and a date had been incorrectly typed in as year 1019 instead of 2019. Since i was inserting using a data array, it was difficult to find the problem until I switched to row-by-row insertion.

This was my old code, which "hid" the problem data.

    Dim DataArray(MyDT.Rows.Count + 1, MyDT.Columns.Count + 1) As Object
    Try
        XL.Range(XL.Cells(2, 1), XL.Cells(MyDT.Rows.Count, MyDT.Columns.Count)).Value = DataArray
    Catch ex As Exception
        MsgBox("Fatal Error in F100 at 1270: " & ex.Message)
        End
    End Try

When inserting the same data by single rows at a time, it stopped with the same error but now it was easy to find the offending data.

I am adding this information so many years later, in case this helps someone else.

I faced same problem worked on it around 3 days. I noticed as our number of records are not much our senior developer keeps 2 images and Fingerprint in database. When I try to fetch this hex values it taking long time, I calculate average time to execute my procedure its around 38 seconds. The default commandtimeout is 30 seconds so its less than average time required to run my stored procedure. I set my commandtimeout like below

cmd.CommandTimeout = 50

and its working fine but sometimes if your query takes more than 50 seconds it will prompt same error.

Change "methodInfo" to "classInstance", just like in the call with the null parameter array.

  result = methodInfo.Invoke(classInstance, parametersArray);

And if you really want to get yourself in trouble, make it easier to execute by writing an extension method:

static class AccessExtensions
{
    public static object call(this object o, string methodName, params object[] args)
    {
        var mi = o.GetType ().GetMethod (methodName, System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance );
        if (mi != null) {
            return mi.Invoke (o, args);
        }
        return null;
    }
}

And usage:

    class Counter
    {
        public int count { get; private set; }
        void incr(int value) { count += value; }
    }

    [Test]
    public void making_questionable_life_choices()
    {
        Counter c = new Counter ();
        c.call ("incr", 2);             // "incr" is private !
        c.call ("incr", 3);
        Assert.AreEqual (5, c.count);
    }

The Java EE version of Eclipse is not installed, insted a standard SDK version is installed.

You can go to Help > Install New Software then select the Eclipse site from the dropdown (Helios, Kepler depending upon your revision). Then select the option that shows Java EE. Restart Eclipse and you should see the Server list, such as Apache, Oracle, IBM etc.

As you know JBoss is a purely filesystem based installation. To install you simply unzip a file and thats it. Once you install a certain folder structure is created by default and as you run the JBoss instance for the first time, it creates additional folders for runtime operation. For comparison here is the structure of JBoss AS 7 before and after you start for the first time

Before

jboss-as-7
 |
 |---> standalone
 |      |----> lib
 |      |----> configuration
 |      |----> deployments
 |      
 |---> domain
 |....

After

jboss-as-7
     |
     |---> standalone
     |      |----> lib
     |      |----> configuration
     |      |----> deployments
     |      |----> tmp
     |      |----> data
     |      |----> log
     |      
     |---> domain
     |....

As you can see 3 new folders are created (log, data & tmp). These folders can all be deleted without effecting the application deployed in deployments folder unless your application generated Data that's stored in those folders. In development, its ok to delete all these 3 new folders assuming you don't have any need for the logs and data stored in "data" directory.

For production, ITS NOT RECOMMENDED to delete these folders as there maybe application generated data that stores certain state of the application. For ex, in the data folder, the appserver can save critical Tx rollback logs. So contact your JBoss Administrator if you need to delete those folders for any reason in production.

Good luck!

Seems to work

$(".selector").change(function() {

    var $value = $(this).val();

    var $title = $(this).children('option[value='+$value+']').html();

    $('#bacon').val($title);

});

Just check with your firebug. And don't put css on hidden input.

Is this what you are trying?

Option Explicit

Public Sub SaveWorksheetsAsCsv()
    Dim WS As Worksheet
    Dim SaveToDirectory As String, newName As String

    SaveToDirectory = "H:\test\"

    For Each WS In ThisWorkbook.Worksheets
        newName = GetBookName(ThisWorkbook.Name) & "_" & WS.Name
        WS.Copy
        ActiveWorkbook.SaveAs SaveToDirectory & newName, xlCSV
        ActiveWorkbook.Close Savechanges:=False
    Next
End Sub

Function GetBookName(strwb As String) As String
    GetBookName = Left(strwb, (InStrRev(strwb, ".", -1, vbTextCompare) - 1))
End Function

I tried changing year to a different term, and it worked.

public_methods : {
    get: function() {
        return this._year;
    },

    set: function(newValue) {
        if(newValue > this.originYear) {
            this._year = newValue;
            this.edition += newValue - this.originYear;
        }
    }
}

In MySQL, this does return the highest value from the id column:

SELECT MAX(id) FROM tablename;

However, this does not put that id into $n:

$n = mysql_query("SELECT max(id) FROM tablename");

To get the value, you need to do this:

$result = mysql_query("SELECT max(id) FROM tablename");

if (!$result) {
    die('Could not query:' . mysql_error());
}

$id = mysql_result($result, 0, 'id');

If you want to get the last insert ID from A, and insert it into B, you can do it with one command:

INSERT INTO B (col) SELECT MAX(id) FROM A;

In bash:

#!/bin/bash
echo before comment
: <<'END'
bla bla
blurfl
END
echo after comment

The ' and ' around the END delimiter are important, otherwise things inside the block like for example $(command) will be parsed and executed.

For an explanation, see this and this question.

string baseUrl = Request.Url.GetLeftPart(UriPartial.Authority);

Uri::GetLeftPart Method:

The GetLeftPart method returns a string containing the leftmost portion of the URI string, ending with the portion specified by part.

UriPartial Enumeration:

The scheme and authority segments of the URI.

Something like this in your form main. Double click the form in the visual editor to create the form load event.

 Timer Clock=new Timer();
 Clock.Interval=2700000; // not sure if this length of time will work 
 Clock.Start();
 Clock.Tick+=new EventHandler(Timer_Tick);

Then add an event handler to do something when the timer fires.

  public void Timer_Tick(object sender,EventArgs eArgs)
  {
    if(sender==Clock)
    {
      // do something here      
    }
  }

Here is one of the example/variant (more detail described) of ToggleButton using jQuery with <label for="input"> implementation.

1st we will create container for our ToggleButton using classic HTML <input> and <label>

<span>
  <input type="checkbox" value="1" name="some_feature_to_select" id="feature_cb" style="display: none;"> <!-- We can hide checkbox bec. we want <label> to be a ToggleButton, so we don't need to show it. It is used as our value holder -->
  <label for="feature_cb" id="label_for_some_feature">
    <img alt="Stylish image" src="/images/icons/feature.png">
  </label>
</span>

Next we will define function for toggling our button. Our button actually is the usual <label> which we will be styling to represent value toggling.

function toggleButton(button) {

var _for = button.getAttribute('for'); // defining for which element this label is (suppose element is a checkbox (bec. we are making ToggleButton ;) )
var _toggleID = 'input#'+_for; // composing selector ID string to select our toggle element (checkbox)
var _toggle = $( _toggleID ); // selecting checkbox to work on
var isChecked = !_toggle.is(':checked'); // defining the state with negation bec. change value event will have place later, so we negating current state to retrieve inverse (next).

if (isChecked)
    $(button).addClass('SelectedButtonClass'); // if it is checked -> adding nice class to our button (<label> in our case) to show that value was toggled
else
    $(button).removeClass('SelectedButtonClass'); // if value (or feature) was unselected by clicking the button (<label>) -> removing .SelectedButtonClass (or simply removing all classes from element)
}

Function is implemented in a reusable way. You can use it for more than one, two or even three ToggleButtons you've created.

... and finally ... to make it work as expected, we should bind toggle function to an event ("change" event) of our improvised <label> button (it will be click event bec. we are not altering the checkbox directly, so no change event can be fired for <label>).

$(document).ready(function(){

    $("#some_feature_label").click(function () {
        toggleButton(this); // call function with transmitting instance of a clicked label and let the script decide what was toggled and what to do with it
    });

    $("#some_other_feature_label").click(function () {
        toggleButton(this); // doing the same for any other feature we want to represent in a way of ToggleButton
    });

});

With CSS we can define backgorund-image or some border to represent the change in value whilst <label> will do the job for us in altering the value of a checkbox ;).

Hope this helps someone.

I use the following code as a simple sliding window that uses generators to drastically increase readability. Its speed has so far been sufficient for use in bioinformatics sequence analysis in my experience.

I include it here because I didn't see this method used yet. Again, I make no claims about its compared performance.

def slidingWindow(sequence,winSize,step=1):
"""Returns a generator that will iterate through
the defined chunks of input sequence. Input sequence
must be sliceable."""

    # Verify the inputs
    if not ((type(winSize) == type(0)) and (type(step) == type(0))):
        raise Exception("**ERROR** type(winSize) and type(step) must be int.")
    if step > winSize:
        raise Exception("**ERROR** step must not be larger than winSize.")
    if winSize > len(sequence):
        raise Exception("**ERROR** winSize must not be larger than sequence length.")

    # Pre-compute number of chunks to emit
    numOfChunks = ((len(sequence)-winSize)/step)+1

    # Do the work
    for i in range(0,numOfChunks*step,step):
        yield sequence[i:i+winSize]

You can't use WebSockets over HTTPS, but you can use WebSockets over TLS (HTTPS is HTTP over TLS). Just use "wss://" in the URI.

I believe recent version of Firefox won't let you use non-TLS WebSockets from an HTTPS page, but the reverse shouldn't be a problem.

Here is how I did it!

//create the font

try {
    //create the font to use. Specify the size!
    Font customFont = Font.createFont(Font.TRUETYPE_FONT, new File("Fonts\\custom_font.ttf")).deriveFont(12f);
    GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
    //register the font
    ge.registerFont(customFont);
} catch (IOException e) {
    e.printStackTrace();
} catch(FontFormatException e) {
    e.printStackTrace();
}

//use the font
yourSwingComponent.setFont(customFont);

In PostMan we have ->Pre-request Script. Paste the Below snippet.

const dateNow = new Date();
postman.setGlobalVariable("todayDate", dateNow.toLocaleDateString());

And now we are ready to use.

{
"firstName": "SANKAR",
"lastName": "B",
"email": "[email protected]",
"creationDate": "{{todayDate}}"
}

If you are using JPA Entity classes then use the below snippet

    @JsonFormat(pattern="MM/dd/yyyy")
    @Column(name = "creation_date")
    private Date creationDate;

Someone with more reputation can copy this into the main answer:

• Change Tracking. Allows you to get info on what changes happened to which rows since a specific version.
• Change Data Capture. Allows all changes to be captured and queried. (Enterprise)

I made a small recursive function that goes through the entire json object and saves the key path and its value.

// My stored keys and values from the json object
HashMap<String,String> myKeyValues = new HashMap<String,String>();

// Used for constructing the path to the key in the json object
Stack<String> key_path = new Stack<String>();

// Recursive function that goes through a json object and stores 
// its key and values in the hashmap 
private void loadJson(JSONObject json){
    Iterator<?> json_keys = json.keys();

    while( json_keys.hasNext() ){
        String json_key = (String)json_keys.next();

        try{
            key_path.push(json_key);
            loadJson(json.getJSONObject(json_key));
       }catch (JSONException e){
           // Build the path to the key
           String key = "";
           for(String sub_key: key_path){
               key += sub_key+".";
           }
           key = key.substring(0,key.length()-1);

           System.out.println(key+": "+json.getString(json_key));
           key_path.pop();
           myKeyValues.put(key, json.getString(json_key));
        }
    }
    if(key_path.size() > 0){
        key_path.pop();
    }
}

var objectA = {}

is a lot quicker and, in my experience, more commonly used, so it's probably best to adopt the 'standard' and save some typing.

If this is just plain vanilla C, then:

strcpy(buffer, text.c_str());

Assuming that buffer is allocated and large enough to hold the contents of 'text', which is the assumption in your original code.

If encrypt() takes a 'const char *' then you can use

encrypt(text.c_str())

and you do not need to copy the string.

• Bandwidth - theoretical maximum units of work per unit of time

As opposed to the time per unit of work (speed/latency).

This question in network engineering stack exchange contains good responses: https://networkengineering.stackexchange.com/questions/10504/what-is-the-difference-between-data-rate-and-latency

fastest way is by signing with the debug keystore:

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore ~/.android/debug.keystore app.apk androiddebugkey -storepass android

or on Windows:

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore %USERPROFILE%/.android/debug.keystore test.apk androiddebugkey -storepass android

For multilined elements, why not something like

$ array=($(echo -e $'a a\nb b' | tr ' ' '§')) && array=("${array[@]//§/ }") && echo "${array[@]/%/ INTERELEMENT}"

a a INTERELEMENT b b INTERELEMENT

If you really need to do this, use reverse proxy.

For example, with nginx as reverse proxy

server {
  listen       api.mydomain.com:80;
  server_name  api.mydomain.com;
  location / {
    proxy_pass http://127.0.0.1:8000;
  }
}

You can get and set environment variables via os.environ:

import os
user_home = os.environ["HOME"]

os.environ["PYTHONPATH"] = "..."

But since your interpreter is already running, this will have no effect. You're better off using

import sys
sys.path.append("...")

which is the array that your PYTHONPATH will be transformed into on interpreter startup.

Use HttpClientBuilder to build the HttpClient instead of using DefaultHttpClient

ex:

MinimalHttpClient httpclient = new HttpClientBuilder().build();

 // Prepare a request object
 HttpGet httpget = new HttpGet("http://www.apache.org/");

Let me make a recap.

When you build a view containing object of different owners, those other owners have to grant "with grant option" to the owner of the view. So, the view owner can grant to other users or schemas....

Example: User_a is the owner of a table called mine_a User_b is the owner of a table called yours_b

Let's say user_b wants to create a view with a join of mine_a and yours_b

For the view to work fine, user_a has to give "grant select on mine_a to user_b with grant option"

Then user_b can grant select on that view to everybody.

When I had this issue with tf.train.string_input_producer() and tf.train.batch() initializing the local variables before I started the Coordinator solved the problem. I had been getting the error when I initialized the local variables after starting the Coordinator.

Even simpler is to use:

(?P<project_id>\w+|)

The "(a|b)" means a or b, so in your case it would be one or more word characters (\w+) or nothing.

So it would look like:

url(
    r'^project_config/(?P<product>\w+)/(?P<project_id>\w+|)/$',

Not enough reputation to comment yet so I'll just put this here:

To expand on Micah's answer - the browser runs your code top to bottom, so if you write:

<div id="chart"></div>
<script>var svg = d3.select("#chart").append("svg:svg");</script>

The browser will create a div with id "chart", and then run your script, which will try to find that div, and, hurray, success.

Otherwise if you write:

<script>var svg = d3.select("#chart").append("svg:svg");</script>
<div id="chart"></div>

The browser runs your script, and tries to find a div with id chart, but it hasn't been created yet so it fails.

THEN the browser creates a div with id "chart".

TRUNCATE `log_url_info`;
TRUNCATE `log_visitor_info`;
TRUNCATE `index_event`;
TRUNCATE `log_visitor`;
TRUNCATE `log_url`;
TRUNCATE `report_event`;
TRUNCATE `dataflow_batch_import`;
TRUNCATE `dataflow_batch_export`;

I just use it.

I don't think it's necessary to use semi-quotes around the variables, try:

curl -XPOST 'http://localhost/Service' -d "path=%2fxyz%2fpqr%2ftest%2f&fileName=1.doc"

%2f is the escape code for a /.

Also, do you need to specify a port? ( just checking :) )

I get this one all the time. It means that the user started to download a file, and then it either failed, or they cancelled it.

To reproduce the exception try do this yourself - however I'm unaware of any ways to prevent it (except for handling this specific exception only).

You need to decide what the best way forward is depending on your app.

    private String temp = "mahesh.hiren.darshan";

    String s_temp[] = temp.split("[.]");

  Log.e("1", ""+s_temp[0]);

None of these solutions will work for Lollipop as is. In Lollipop activityRootView.getRootView().getHeight() includes the height of the button bar, while measuring the view does not. I've adapted the best/simplest solution above to work with Lollipop.

    final View activityRootView = findViewById(R.id.activityRoot);
activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
  @Override
  public void onGlobalLayout() {
    Rect r = new Rect();
    //r will be populated with the coordinates of your view that area still visible.
    activityRootView.getWindowVisibleDisplayFrame(r);

    int heightDiff = activityRootView.getRootView().getHeight() - (r.bottom - r.top);
    Resources res = getResources();
    // The status bar is 25dp, use 50dp for assurance
    float maxDiff =
        TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 50, res.getDisplayMetrics());

    //Lollipop includes button bar in the root. Add height of button bar (48dp) to maxDiff
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
      float buttonBarHeight =
          TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 48, res.getDisplayMetrics());
      maxDiff += buttonBarHeight;
    }
    if (heightDiff > maxDiff) { // if more than 100 pixels, its probably a keyboard...
      ...do something here
    }
  }
});

Please use an existing secure PHP encryption library

It's generally a bad idea to write your own cryptography unless you have experience breaking other peoples' cryptography implementations.

None of the examples here authenticate the ciphertext, which leaves them vulnerable to bit-rewriting attacks.

If you can install PECL extensions, libsodium is even better

<?php
// PECL libsodium 0.2.1 and newer

/**
 * Encrypt a message
 * 
 * @param string $message - message to encrypt
 * @param string $key - encryption key
 * @return string
 */
function safeEncrypt($message, $key)
{
    $nonce = \Sodium\randombytes_buf(
        \Sodium\CRYPTO_SECRETBOX_NONCEBYTES
    );

    return base64_encode(
        $nonce.
        \Sodium\crypto_secretbox(
            $message,
            $nonce,
            $key
        )
    );
}

/**
 * Decrypt a message
 * 
 * @param string $encrypted - message encrypted with safeEncrypt()
 * @param string $key - encryption key
 * @return string
 */
function safeDecrypt($encrypted, $key)
{   
    $decoded = base64_decode($encrypted);
    $nonce = mb_substr($decoded, 0, \Sodium\CRYPTO_SECRETBOX_NONCEBYTES, '8bit');
    $ciphertext = mb_substr($decoded, \Sodium\CRYPTO_SECRETBOX_NONCEBYTES, null, '8bit');

    return \Sodium\crypto_secretbox_open(
        $ciphertext,
        $nonce,
        $key
    );
}    

Then to test it out:

<?php
// This refers to the previous code block.
require "safeCrypto.php"; 

// Do this once then store it somehow:
$key = \Sodium\randombytes_buf(\Sodium\CRYPTO_SECRETBOX_KEYBYTES);
$message = 'We are all living in a yellow submarine';

$ciphertext = safeEncrypt($message, $key);
$plaintext = safeDecrypt($ciphertext, $key);

var_dump($ciphertext);
var_dump($plaintext);

This can be used in any situation where you are passing data to the client (e.g. encrypted cookies for sessions without server-side storage, encrypted URL parameters, etc.) with a reasonably high degree of certainty that the end user cannot decipher or reliably tamper with it.

Since libsodium is cross-platform, this also makes it easier to communicate with PHP from, e.g. Java applets or native mobile apps.

Note: If you specifically need to add encrypted cookies powered by libsodium to your app, my employer Paragon Initiative Enterprises is developing a library called Halite that does all of this for you.

git remote set-url --push origin should work, as you mentioned, but you need to explicitly provide the url instead of an alternative remote name, e.g.

git remote set-url --push origin [email protected]:contributor/repo.git

You can confirm whether this worked by doing a git remote -v. E.g.

? ~/go/src/github.com/stretchr/testify/ master git remote -v
fork    [email protected]:contributor/testify.git (fetch)
fork    [email protected]:contributor/testify.git (push)
origin  [email protected]:stretchr/testify (fetch)
origin  [email protected]:contributor/testify.git (push)

I say you setup the JAVA_HOME environment variable like Pascal is saying: In Cygwin if you use bash as your shell should be:

export JAVA_HOME=/cygdrive/c/pathtothejdk

It never harms to also prepend the java bin directory path to the PATH environment variable with:

export PATH=${JAVA_HOME}/bin:${PATH}

Also add maven-enforce-plugin to make sure the right JDK is used. This is a good practice for your pom.

 <plugins>
   <plugin>
      <groupId>org.apache.maven.plugins</groupId>

If you want your scripts to load after page has been rendered, you can use:

function getScript(a, b) {
    var c = document.createElement("script");
    c.src = a;
    var d = document.getElementsByTagName("head")[0],
        done = false;
    c.onload = c.onreadystatechange = function() {
        if (!done && (!this.readyState || this.readyState == "loaded" || this.readyState == "complete")) {
            done = true;
            b();
            c.onload = c.onreadystatechange = null;
            d.removeChild(c)
        }
    };
    d.appendChild(c)
}

//call the function
getScript("http://www.google-analytics.com/ga.js", function() {
    // do stuff after the script has loaded
});

I would recommend not to use HTTP authentication with custom scheme names. If you feel that you have something of generic use, you can define a new scheme, though. See http://greenbytes.de/tech/webdav/draft-ietf-httpbis-p7-auth-latest.html#rfc.section.2.3 for details.

The accepted answer is outdated. So first, pip is preferred over easy_install, (Why use pip over easy_install?). Then follow these steps to install pip on Windows, it's quite easy.

1. Install setuptools:

   curl https://bootstrap.pypa.io/ez_setup.py | python
   

2. Install pip:

   curl https://bootstrap.pypa.io/get-pip.py | python
   

3. Optionally, you can add the path to your environment so that you can use pip anywhere. It's somewhere like C:\Python33\Scripts.

There are three approaches

• Use SublimeCodeIntel plug-in

• Use CTags plug-in

• Generate .sublime-completion file manually

Approaches are described in detail in this blog post (of mine): http://opensourcehacker.com/2013/03/04/javascript-autocompletions-and-having-one-for-sublime-text-2/

This is the RegKey I used:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Command Processor]
"DisableUNCCheck"=dword:00000001

When you use laravel modules, you may add the name's module:

@include('cimple::shared.posts_list')

I use:

if exists (select * 
           from sys.tables 
           where name = 'tableName' 
           and schema_id = schema_id('dbo'))
begin
    drop table dbo.tableName
end

This..

(
        (meta_key = 'lat' AND meta_value >= '60.23457047672217')
    OR
        (meta_key = 'lat' AND meta_value <= '60.23457047672217')
)

is the same as

(
        (meta_key = 'lat')
)

Adding it all together (the same applies to the long filter) you have this impossible WHERE clause which will give no rows because meta_key cannot be 2 values in one row

WHERE
    (meta_key = 'lat' AND meta_key = 'long' )

You need to review your operators to make sure you get the correct logic

Take Pods-resources.sh from project path and paste in Terminal

sudo chmod a+x "Pods-resources.sh file path here"

For Finding All the ChildNodes you can use the below Snippet

List<WebElement> childs = MyCurrentWebElement.findElements(By.xpath("./child::*"));

        for (WebElement e  : childs)
        {
            System.out.println(e.getTagName());
        }

Note that this will give all the Child Nodes at same level -> Like if you have structure like this :

<Html> 
<body> 
 <div> ---suppose this is current WebElement 
   <a>
   <a>
      <img>
          <a>
      <img>
   <a>

It will give me tag names of 3 anchor tags here only . If you want all the child Elements recursively , you can replace the above code with MyCurrentWebElement.findElements(By.xpath(".//*"));

Hope That Helps !!

You can increase client_max_body_size and upload_max_filesize + post_max_size all day long. Without adjusting HTTP timeout it will never work.

//You need to adjust this, and probably on PHP side also. client_body_timeout 2min // 1GB fileupload

It looks like your $pdo variable is not initialized. I can't see in the code you've uploaded where you are initializing it.

Make sure you create a new PDO object in the global scope before calling the class methods. (You should declare it in the global scope because of how you implemented the methods inside the Category class).

$pdo = new PDO('mysql:host=localhost;dbname=test', $user, $pass);

This is naive, but I had to make it to be POSIX compliant. Requires permission to cd into the file's directory.

  exit 1

  dir=$( cd ${1}; echo ${PWD%${base}} )

  if [ ${dir} = / ]; then
    parentPath=${dir}
  else
    parentPath=${dir%/}
  fi

  if [ -z ${base} ] || [ -z ${parentPath} ]; then
    if [ -n ${1} ]; then
      fullPath=$( cd ${1}; echo ${PWD} )
    else

      exit 1
    fi
  fi

elif [ ${1%/*} = ${1} ]; then

  if [ -f ./${1} ]; then


    # File in current directory

    base=$( echo ${1##*/} )
    parentPath=$( echo ${PWD} )

  else
    echo "Error: unsupported scenario 2" >&2
    exit 1

  echo "Error: not file or directory" >&2
  exit 1

When you choose any value from spinner, then you get selected value,

As another cheap alternative on somewhat static canvas, using an overlaying img element with a usemap definition is quick and dirty. Works especially well on polygon based canvas elements like a pie chart.

This an old question, but I have had to explain it to someone recently and I thought recording the answer here would be helpful at least in understanding how C works.

String literals like

"a"

or

"This is a string"

are put in the text or data segments of your program.

A string in C is actually a pointer to a char, and the string is understood to be the subsequent chars in memory up until a NUL char is encountered. That is, C doesn't really know about strings.

So if I have

char *s1 = "This is a string";

then s1 is a pointer to the first byte of the string.

Now, if I have

char *s2 = "This is a string";

this is also a pointer to the same first byte of that string in the text or data segment of the program.

But if I have

char *s3 = malloc( 17 );
strcpy(s3, "This is a string");

then s3 is a pointer to another place in memory into which I copy all the bytes of the other strings.

Illustrative examples:

Although, as your compiler rightly points out, you shouldn't do this, the following will evaluate to true:

s1 == s2 // True: we are comparing two pointers that contain the same address

but the following will evaluate to false

s1 == s3 // False: Comparing two pointers that don't hold the same address.

And although it might be tempting to have something like this:

struct Vehicle{
    char *type;
    // other stuff
}

if( type == "Car" )
   //blah1
else if( type == "Motorcycle )
   //blah2

You shouldn't do it because it's not something that is guarantied to work. Even if you know that type will always be set using a string literal.

I have tested it and it works. If I do

A.type = "Car";

then blah1 gets executed and similarly for "Motorcycle". And you'd be able to do things like

if( A.type == B.type )

but this is just terrible. I'm writing about it because I think it's interesting to know why it works, and it helps understand why you shouldn't do it.

Solutions:

In your case, what you want to do is use strcmp(a,b) == 0 to replace a == b

In the case of my example, you should use an enum.

enum type {CAR = 0, MOTORCYCLE = 1}

The preceding thing with string was useful because you could print the type, so you might have an array like this

char *types[] = {"Car", "Motorcycle"};

And now that I think about it, this is error prone since one must be careful to maintain the same order in the types array.

Therefore it might be better to do

char *getTypeString(int type)
{
    switch(type)
    case CAR: return "Car";
    case MOTORCYCLE: return "Motorcycle"
    default: return NULL;
}

For future reference - the Line2D artist returned by plot() also has a set_markevery() method which allows you to only set markers on certain points - see https://matplotlib.org/api/_as_gen/matplotlib.lines.Line2D.html#matplotlib.lines.Line2D.set_markevery

In the eve of the semantic web, correctness is something to consider. Unfortunately, PHP's "Location"-header still uses the HTTP 302-redirect code, which, strictly, isn't the best one for redirection. The one it should use instead, is the 303 one.

W3C is kind enough to mention that the 303-header is incompatible with "many pre-HTTP/1.1 user agents," which would amount to no browser in current use. So, the 302 is a relic, which shouldn't be used.

...or you could just ignore it, as everyone else...

Just as a normal js object:

let myhash: IHash = {};   

myhash["somestring"] = "value"; //set

let value = myhash["somestring"]; //get

There are two things you're doing with [indexer: string] : string

• tell TypeScript that the object can have any string-based key
• that for all key entries the value MUST be a string type.

You can make a general dictionary with explicitly typed fields by using [key: string]: any;

e.g. age must be number, while name must be a string - both are required. Any implicit field can be any type of value.

As an alternative, there is a Map class:

let map = new Map<object, string>(); 

let key = new Object();

map.set(key, "value");
map.get(key); // return "value"

This allows you have any Object instance (not just number/string) as the key.

Although its relatively new so you may have to polyfill it if you target old systems.

When you say "I'd like to have number of such images stored in dictionary", it's not clear if this is an in-memory structure or not.

You don't need to do any of this to meek an image in memory. Just keep the image object in your dictionary.

If you're going to write your dictionary to a file, you might want to look at im.tostring() method and the Image.fromstring() function

http://effbot.org/imagingbook/image.htm

im.tostring() => string

Returns a string containing pixel data, using the standard "raw" encoder.

Image.fromstring(mode, size, data) => image

Creates an image memory from pixel data in a string, using the standard "raw" decoder.

The "format" (.jpeg, .png, etc.) only matters on disk when you are exchanging the files. If you're not exchanging files, format doesn't matter.

Select fonts by specifying the weights you need on load

Font-families consist of several distinct fonts

For example, extra-bold will make the font look quite different in say, Photoshop, because you're selecting a different font. The same applies to italic font, which can look very different indeed. Setting font-weight:800 or font-style:italic may result in just a best effort of the web browser to fatten or slant the normal font in the family.

Even though you're loading a font-family, you must specify the weights and styles you need for some web browsers to let you select a different font in the family with font-weight and font-style.

Example

This example specifies the light, normal, normal italic, bold, and extra-bold fonts in the font family Open Sans:

<html>_x000D_
  <head>_x000D_
    <link rel="stylesheet"_x000D_
          href="https://fonts.googleapis.com/css?family=Open+Sans:100,400,400i,600,800">_x000D_
    <style>_x000D_
      body {_x000D_
        font-family: 'Open Sans', serif;_x000D_
        font-size: 48px;_x000D_
      }_x000D_
    </style>_x000D_
  </head>_x000D_
  <body>    _x000D_
    <div style="font-weight:400">Didn't work with all the fonts</div>_x000D_
   <div style="font-weight:600">Didn't work with all the fonts</div>_x000D_
   <div style="font-weight:800">Didn't work with all the fonts</div>_x000D_
  </body>_x000D_
</html>

Reference

Testing

Tested working in Firefox 66.0.3 on Mac and Firefox 36.0.1 in Windows.

Non-Google fonts

Other fonts must be uploaded to the server, style and weight specified by their individual names.

System fonts

Assume nothing, font-wise, about what device is visiting your website or what fonts are installed on its OS.

(You may use the fall-backs of serif and sans-serif, but you will get the font mapped to these by the individual web browser version used, within the fonts available in the OS version it's running under, and not what you designed.)

Testing should be done with the font temporarily uninstalled from your system, to be sure that your design is in effect.

This works with our libraries running GIT v1.7.1, where we have a DEV package repo and LIVE package repo. The repositories themselves are nothing but a shell to package the assets for a project. all submodules.

The LIVE is never updated intentionally, however cache files or accidents can occur, leaving the repo dirty. New submodules added to the DEV must be initialized within LIVE as well.

Package Repository in DEV

Here we want to pull all upstream changes that we are not yet aware of, then we will update our package repository.

# Recursively reset to the last HEAD
git submodule foreach --recursive git reset --hard

# Recursively cleanup all files and directories
git submodule foreach --recursive git clean -fd

# Recursively pull the upstream master
git submodule foreach --recursive git pull origin master

# Add / Commit / Push all updates to the package repo
git add .
git commit -m "Updates submodules"
git push   

Package Repository in LIVE

Here we want to pull the changes that are committed to the DEV repository, but not unknown upstream changes.

# Pull changes
git pull

# Pull status (this is required for the submodule update to work)
git status

# Initialize / Update 
git submodule update --init --recursive

you have an array of int which is a primitive type, primitive type doesn't have the method add. You should look for Collections.

Although the answers above seems correct, just a simple explanation to give you an idea of how it works.

Suppose that your column is set to be DECIMAL(13,4). This means that the column will have a total size of 13 digits where 4 of these will be used for precision representation.

So, in summary, for that column you would have a max value of: 999999999.9999

Darrel is of course right on with his response. One thing to add is that the reason why attempting to bind to a body containing a single token like "hello".

is that it isn’t quite URL form encoded data. By adding “=” in front like this:

=hello

it becomes a URL form encoding of a single key value pair with an empty name and value of “hello”.

However, a better solution is to use application/json when uploading a string:

POST /api/sample HTTP/1.1
Content-Type: application/json; charset=utf-8
Host: host:8080
Content-Length: 7

"Hello"

Using HttpClient you can do it as follows:

HttpClient client = new HttpClient();
HttpResponseMessage response = await client.PostAsJsonAsync(_baseAddress + "api/json", "Hello");
string result = await response.Content.ReadAsStringAsync();
Console.WriteLine(result);

According to this post, you should enable it in XCode.

1. Click on your project in the Project Navigator
2. Open the Info tab
3. Click on the down arrow left to the "App Transport Security Settings"
4. Right click on "App Transport Security Settings" and select Add Row
5. For created row set the key “Allow Arbitrary Loads“, type to boolean and value to YES.

Suggestion 1

When you add an object to $stateProvider.state that object is then passed with the state. So you can add additional properties which you can read later on when needed.

Example route configuration

$stateProvider
.state('public', {
    abstract: true,
    module: 'public'
})
.state('public.login', {
    url: '/login',
    module: 'public'
})
.state('tool', {
    abstract: true,
    module: 'private'
})
.state('tool.suggestions', {
    url: '/suggestions',
    module: 'private'
});

The $stateChangeStart event gives you acces to the toState and fromState objects. These state objects will contain the configuration properties.

Example check for the custom module property

$rootScope.$on('$stateChangeStart', function(e, toState, toParams, fromState, fromParams) {
    if (toState.module === 'private' && !$cookies.Session) {
        // If logged out and transitioning to a logged in page:
        e.preventDefault();
        $state.go('public.login');
    } else if (toState.module === 'public' && $cookies.Session) {
        // If logged in and transitioning to a logged out page:
        e.preventDefault();
        $state.go('tool.suggestions');
    };
});

I didn't change the logic of the cookies because I think that is out of scope for your question.

Suggestion 2

You can create a Helper to get you this to work more modular.

Value publicStates

myApp.value('publicStates', function(){
    return {
      module: 'public',
      routes: [{
        name: 'login', 
        config: { 
          url: '/login'
        }
      }]
    };
});

Value privateStates

myApp.value('privateStates', function(){
    return {
      module: 'private',
      routes: [{
        name: 'suggestions', 
        config: { 
          url: '/suggestions'
        }
      }]
    };
});

The Helper

myApp.provider('stateshelperConfig', function () {
  this.config = {
    // These are the properties we need to set
    // $stateProvider: undefined
    process: function (stateConfigs){
      var module = stateConfigs.module;
      $stateProvider = this.$stateProvider;
      $stateProvider.state(module, {
        abstract: true,
        module: module
      });
      angular.forEach(stateConfigs, function (route){
        route.config.module = module;
        $stateProvider.state(module + route.name, route.config);
      });
    }
  };

  this.$get = function () {
    return {
      config: this.config
    };
  };
});

Now you can use the helper to add the state configuration to your state configuration.

myApp.config(['$stateProvider', '$urlRouterProvider', 
    'stateshelperConfigProvider', 'publicStates', 'privateStates',
  function ($stateProvider, $urlRouterProvider, helper, publicStates, privateStates) {
    helper.config.$stateProvider = $stateProvider;
    helper.process(publicStates);
    helper.process(privateStates);
}]);

This way you can abstract the repeated code, and come up with a more modular solution.

Note: the code above isn't tested

CodeLens is not available in the Community editions. You need Professional or higher to switch it on.

In VS2015, one way to "get" CodeLens was to install the SQL Server Developer Tools (SSDT) but I believe this has been rectified in VS2017.

Still you can get all method reference by right clicking on the method and "Find All references"

REPEAT
    ...
UNTIL cond

Is equivalent to

while True:
    ...
    if cond:
        break

Try changing your code to this:

private void Test()
{            
    System.IO.MemoryStream data = new System.IO.MemoryStream(TestStream());

    byte[] buf = new byte[data.Length];
    data.Read(buf, 0, buf.Length);                       
}

I had this error in tests, the directive templateUrl wasn't trusted, but only for the spec, so I added the template directory:

beforeEach(angular.mock.module('app.templates'));

My main directory is app.

Great question!

There are many websites and free web apps implemented in PHP that run on Apache, lots of people use it so you can mash up something pretty easy and besides, its a no-brainer way of serving static content. Node is fast, powerful, elegant, and a sexy tool with the raw power of V8 and a flat stack with no in-built dependencies.

I also want the ease/flexibility of Apache and yet the grunt and elegance of Node.JS, why can't I have both?

Fortunately with the ProxyPass directive in the Apache httpd.conf its not too hard to pipe all requests on a particular URL to your Node.JS application.

ProxyPass /node http://localhost:8000

Also, make sure the following lines are NOT commented out so you get the right proxy and submodule to reroute http requests:

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so

Then run your Node app on port 8000!

var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello Apache!\n');
}).listen(8000, '127.0.0.1');

Then you can access all Node.JS logic using the /node/ path on your url, the rest of the website can be left to Apache to host your existing PHP pages:

Now the only thing left is convincing your hosting company let your run with this configuration!!!

I had a horizontal scrolling collection view (I use collection view in Tableview) and I too faced problems withcell reuse, whenever I select one item and scroll towards right, some other cells in the next visible set gets select automatically. Trying to solve this using any custom cell properties like "selected", highlighted etc didnt help me so I came up with the below solution and this worked for me.

Step1:

Create a variable in the collectionView to store the selected index, here I have used a class level variable called selectedIndex

- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath

{

    MyCVCell *cell = (MyCVCell*)[collectionView dequeueReusableCellWithReuseIdentifier:@"MyCVCell" forIndexPath:indexPath];    

// When scrolling happens, set the selection status only if the index matches the selected Index

if (selectedIndex == indexPath.row) {

        cell.layer.borderWidth = 1.0;

        cell.layer.borderColor = [[UIColor redColor] CGColor];

    }
    else
    {
        // Turn off the selection
        cell.layer.borderWidth = 0.0;

    }
    return cell;

}
- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath

{
    MyCVCell *cell = (MyCVCell *)[collectionView cellForItemAtIndexPath:indexPath];
    // Set the index once user taps on a cell
    selectedIndex = indexPath.row;
    // Set the selection here so that selection of cell is shown to ur user immediately
    cell.layer.borderWidth = 1.0;
    cell.layer.borderColor = [[UIColor redColor] CGColor];
    [cell setNeedsDisplay];
}

- (void)collectionView:(UICollectionView *)collectionView didDeselectItemAtIndexPath:(NSIndexPath *)indexPath

{

    MyCVCell *cell = (MyCVCell *)[collectionView cellForItemAtIndexPath:indexPath];

    // Set the index to an invalid value so that the cells get deselected
    selectedIndex = -1;
    cell.layer.borderWidth = 0.0;
    [cell setNeedsDisplay];

}

-anoop

After some trials, knowing that I had all the factors stated in this thread and other threads properly configured, I still got this error in Android Studio.

Even after installing externally, it seems Android Studio could not discover that HAXM is already installed, unless it gets to install it itself.

As a solution that worked for me, under User\AppData\Local\Android\sdk\extras\intel\Hardware_Accelerated_Execution_Manager which android has downloaded when attempting to install HAXM, click the installer and uninstall the software, then re-try from Android Studio to install it, it should work now.

If you want add a string with the value use this:

<TextBlock Text="{Binding Date, StringFormat= 'Date : {0:d}'}" />

The sizzle selector engine (what powers JQuery) is perfectly geared up for this:

var elements = $('input[type=text]');

Or

var elements = $('input:text');

If it's a value you'd like to have for every request & template, using a context processor is more appropriate.

Here's how:

1. Make a context_processors.py file in your app directory. Let's say I want to have the ADMIN_PREFIX_VALUE value in every context:

   from django.conf import settings # import the settings file
   
   def admin_media(request):
       # return the value you want as a dictionnary. you may add multiple values in there.
       return {'ADMIN_MEDIA_URL': settings.ADMIN_MEDIA_PREFIX}
   

2. add your context processor to your settings.py file:

   TEMPLATES = [{
       # whatever comes before
       'OPTIONS': {
           'context_processors': [
               # whatever comes before
               "your_app.context_processors.admin_media",
           ],
       }
   }]
   

3. Use RequestContext in your view to add your context processors in your template. The render shortcut does this automatically:

   from django.shortcuts import render
   
   def my_view(request):
       return render(request, "index.html")
   

4. and finally, in your template:

   ...
   <a href="{{ ADMIN_MEDIA_URL }}">path to admin media</a>
   ...
   

Simply casting the string as an int won't work reliably. You need to convert it to an int32. For this you can use the .NET convert class and its ToInt32 method. The method requires a string ($strNum) as the main input, and the base number (10) for the number system to convert to. This is because you can not only convert to the decimal system (the 10 base number), but also to, for example, the binary system (base 2).

Give this method a try:

[string]$strNum = "1.500"
[int]$intNum = [convert]::ToInt32($strNum, 10)

$intNum

<script>
       $(document).ready(function () {
           $('select').attr("id", "newId"); //direct descendant of a
       });
</script>

This could do for all purpose. Just add before your body closing tag and don't for get to add Jquery.min.js

I'm resurrecting the dead here, but because a range can be defined as "A:A", using a for each loop ends up with a potential infinite loop. The solution, as far as I know, is to use the Do Until loop.

Do Until Selection.Value = ""
  Rem Do things here...
Loop

You can very easily use this to re-use the value of the variable in another function.

// Use this in source window.var1= oEvent.getSource().getBindingContext();

// Get value of var1 in destination var var2= window.var1;

Instead of doing this via an SQL query use the php function: mysqli::set_charset mysqli_set_charset

Note:

This is the preferred way to change the charset. Using mysqli_query() to set it (such as SET NAMES utf8) is not recommended.

See the MySQL character set concepts section for more information.

To generate classes from WSDL, all you need is build-helper-maven-plugin and jaxws-maven-plugin in your pom.xml
Make sure you have placed wsdl under folder src/main/resources/wsdl and corresponding schema in src/main/resources/schema, run command "mvn generate-sources" from Project root directory.

C:/Project root directory > mvn generate-sources

generated java classes can be located under folder

You can Also use this online tool to customize your button http://angrytools.com/android/button/ and use android:background="@drawable/custom_btn" to define the customized button in your layout.

You can play with delay prop of animation, just set visibility:visible after a delay, demo:

@keyframes delayedShow {_x000D_
  to {_x000D_
    visibility: visible;_x000D_
  }_x000D_
}_x000D_
_x000D_
.delayedShow{_x000D_
  visibility: hidden;_x000D_
  animation: 0s linear 2.3s forwards delayedShow ;_x000D_
}

So, Where are you?_x000D_
_x000D_
<div class="delayedShow">_x000D_
  Hey, I'm here!_x000D_
</div>

You may like the way that we do it. I wanted a reversible unique code that looked "random" -a fairly common problem.

• We take an input number such as 1,942.
• Left pad it into a string: "0000001942"
• Put the last two digits onto the front: "4200000019"
• Convert that into a number: 4,200,000,019

We now have a number that varies wildly between calls and is guaranteed to be less than 10,000,000,000. Not a bad start.

• Convert that number to a Base 34 string: "2oevc0b"
• Replace any zeros with 'y' and any ones with 'z': "2oevcyb"
• Upshift: "2OEVCYB"

The reason for choosing base 34 is so that we don't worry about 0/O and 1/l collisions. Now you have a short random-looking key that you can use to look up a LONG database identifier.

Since this post is marked as the duplicate of this other post, I answer here for the "lambda" case, although the OP is not about lambdas.

So, for lambda functions that are not defined in their own lines: in addition to marko.ristin's answer, you may wish to use mini-lambda or use SymPy as suggested in this answer.

• mini-lambda is lighter and supports any kind of operation, but works only for a single variable
• SymPy is heavier but much more equipped with mathematical/calculus operations. In particular it can simplify your expressions. It also supports several variables in the same expression.

Here is how you can do it using mini-lambda:

from mini_lambda import x, is_mini_lambda_expr
import inspect

def get_source_code_str(f):
    if is_mini_lambda_expr(f):
        return f.to_string()
    else:
        return inspect.getsource(f)

# test it

def foo(arg1, arg2):
    # do something with args
    a = arg1 + arg2
    return a

print(get_source_code_str(foo))
print(get_source_code_str(x ** 2))

It correctly yields

def foo(arg1, arg2):
    # do something with args
    a = arg1 + arg2
    return a

x ** 2

See mini-lambda documentation for details. I'm the author by the way ;)

Using com.ibm.etools.marshall.util.BigDecimalRange util class of IBM one can compare if BigDecimal in range.

boolean isCalculatedSumInRange = BigDecimalRange.isInRange(low, high, calculatedSum);

If one need to use the sp_executesql with OUTPUT variables:

EXEC sp_executesql @sql
                  ,N'@p0 INT'
                  ,N'@p1 INT OUTPUT'
                  ,N'@p2 VARCHAR(12) OUTPUT' 
                  ,@p0
                  ,@p1 OUTPUT
                  ,@p2 OUTPUT;

As for current Chrome version (56) you can't remove it yet. Solution provided in other posts leads to overflowing some part of the video.

I've found another solution - you can make the preceding button to overlap the download button and simply cover it, by using this technique:

video::-webkit-media-controls-fullscreen-button {
   margin-right: -48px;
   z-index: 10;
   position: relative;
   background: #fafafa;
   background-image: url(https://image.flaticon.com/icons/svg/151/151926.svg);
   background-size: 35%;
   background-position: 50% 50%;
   background-repeat: no-repeat;
}

Example: https://jsfiddle.net/dk4q6hh2/

PS You might want to customise the icon, since it's for example only.

This is what I've used recently.

CSS

div#tabs p{display:none;}

div#tabs p.tab1:target {display:block;}
div#tabs p.tab2:target {display:block;}
div#tabs p.tab3:target {display:block;}

HTML

<div id='tabs'>
  <h2 class="nav-tab-wrapper">
    <a href="#tab1" class="nav-tab tab1">Pages</a>
    <a href="#tab2" class="nav-tab nav-tab-active tab2">Email</a>
    <a href="#tab3" class="nav-tab tab3">Support</a>
  </h2>

  <p id='tab1' class='tab1'>Awesome tab1 stuff</p>
  <p id='tab2' class='tab2'>Tab2 stuff</p>
  <p id='tab3' class='tab3'>Tab3 stuff</p>

</div>

Hope it helps somewhere.

The solution you posted seems to work in stopping the zoom controls from appearing when the user drags, however there are situations where a user will pinch zoom and the zoom controls will appear. I've noticed that there are 2 ways that the webview will accept pinch zooming, and only one of them causes the zoom controls to appear despite your code:

User Pinch Zooms and controls appear:

ACTION_DOWN
getSettings().setBuiltInZoomControls(false); getSettings().setSupportZoom(false);
ACTION_POINTER_2_DOWN
getSettings().setBuiltInZoomControls(true); getSettings().setSupportZoom(true);
ACTION_MOVE (Repeat several times, as the user moves their fingers)
ACTION_POINTER_2_UP
ACTION_UP

User Pinch Zoom and Controls don't appear:

ACTION_DOWN
getSettings().setBuiltInZoomControls(false); getSettings().setSupportZoom(false);
ACTION_POINTER_2_DOWN
getSettings().setBuiltInZoomControls(true); getSettings().setSupportZoom(true);
ACTION_MOVE (Repeat several times, as the user moves their fingers)
ACTION_POINTER_1_UP
ACTION_POINTER_UP
ACTION_UP

Can you shed more light on your solution?

You have to cast one (or both) of the arguments to the division operator to double:

double firstSolution = (b1 * a22 - b2 * a12) / (double)(a11 * a22 - a12 * a21);

Since you are performing the same calculation twice I'd recommend refactoring your code:

double determinant = a11 * a22 - a12 * a21;
double firstSolution = (b1 * a22 - b2 * a12) / determinant;
double secondSolution = (b2 * a11 - b1 * a21) / determinant;

This works in the same way, but now there is an implicit cast to double. This conversion from int to double is an example of a widening primitive conversion.

You need to use the change directory command 'cd' to change directory

cd C:\Users\MyName\Desktop

you can use cd \d to change the drive as well.

I had the same $count variable in a while loop getting lost issue.

@fedorqui's answer (and a few others) are accurate answers to the actual question: the sub-shell is indeed the problem.

But it lead me to another issue: I wasn't piping a file content... but the output of a series of pipes & greps...

my erroring sample code:

count=0
cat /etc/hosts | head | while read line; do
  ((count++))
  echo $count $line
done
echo $count

and my fix thanks to the help of this thread and the process substitution:

count=0
while IFS= read -r line; do
  ((count++))
  echo "$count $line"
done < <(cat /etc/hosts | head)
echo "$count"

SELECT count(*)
FROM information_schema.columns
WHERE table_name = 'tbl_ifo'

1) You cannot overload the method (Why doesn't ruby support method overloading?) so why not write a new method altogether?

2) I solved a similar problem using the splat operator * for an array of zero or more length. Then, if I want to pass a parameter(s) I can, it is interpreted as an array, but if I want to call the method without any parameter then I don't have to pass anything. See Ruby Programming Language pages 186/187

Use regular expression

var totalWords = "foo love bar very much.";_x000D_
_x000D_
var firstWord = totalWords.replace(/ .*/,'');_x000D_
_x000D_
$('body').append(firstWord);

To avoid any ambiguity, use the utilities methods from SwingUtilities :

SwingUtilities.isLeftMouseButton(MouseEvent anEvent) SwingUtilities.isRightMouseButton(MouseEvent anEvent) SwingUtilities.isMiddleMouseButton(MouseEvent anEvent)

Simply remove the virtual environment from the system.There's no special command for it

rm -rf venv

Adding this link in the open

$(this).parent().appendTo($("form:first"));

works perfectly.

The problem is that you have a circular import: in app.py

from mod_login import mod_login

in mod_login.py

from app import app

This is not permitted in Python. See Circular import dependency in Python for more info. In short, the solution are

• either gather everything in one big file
• delay one of the import using local import

The solution by dglmtn doesn't work when you have a 9-patch drawable with padding as background. Strange things happen, I don't even want to talk about it, if you have such a problem, you know them.

Now, If you want to have a listview with different states and 9-patch drawables (it would work with any drawables and colors, I think) you have to do 2 things:

1. Set the selector for the items in the list.
2. Get rid of the default selector for the list.

What you should do is first set the row_selector.xml:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:state_enabled="true" 
     android:state_pressed="true" android:drawable="@drawable/list_item_bg_pressed" />
    <item android:state_enabled="true"
     android:state_focused="true" android:drawable="@drawable/list_item_bg_focused" />
    <item android:state_enabled="true"
     android:state_selected="true" android:drawable="@drawable/list_item_bg_focused" />
    <item
     android:drawable="@drawable/list_item_bg_normal" />
</selector>

Don't forget the android:state_selected. It works like android:state_focused for the list, but it's applied for the list item.

Now apply the selector to the items (row.xml):

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:background="@drawable/row_selector"
>
...
</RelativeLayout>

Make a transparent selector for the list:

<ListView
    android:id="@+id/android:list"
    ...
    android:listSelector="@android:color/transparent"
    />

This should do the thing.

Moshe's solution is great but the problem may still exist if you need to put the list inside a div. (read: CSS counter-reset on nested list)

This style could prevent that issue:

ol > li {_x000D_
    counter-increment: item;_x000D_
}_x000D_
_x000D_
ol > li:first-child {_x000D_
  counter-reset: item;_x000D_
}_x000D_
_x000D_
ol ol > li {_x000D_
    display: block;_x000D_
}_x000D_
_x000D_
ol ol > li:before {_x000D_
    content: counters(item, ".") ". ";_x000D_
    margin-left: -20px;_x000D_
}

<ol>_x000D_
  <li>list not nested in div</li>_x000D_

Use .ashx file type and use the same code

From jquery.com:

The jqXHR.success(), jqXHR.error(), and jqXHR.complete()
callback methods introduced injQuery 1.5 are deprecated
as of jQuery 1.8. To prepare your code for their eventual 
removal, use jqXHR.done(), jqXHR.fail(), and jqXHR.always() instead.

If you want global handlers you can use:

.ajaxStart(), .ajaxStop(),
.ajaxComplete(), .ajaxError(),
.ajaxSuccess(), .ajaxSend()

Short story: The 0 tells the parser it's dealing with a constant (and not an identifier/reserved word). Something is still needed to specify the number base: the x is an arbitrary choice.

Long story: In the 60's, the prevalent programming number systems were decimal and octal — mainframes had 12, 24 or 36 bits per byte, which is nicely divisible by 3 = log2(8).

The BCPL language used the syntax 8 1234 for octal numbers. When Ken Thompson created B from BCPL, he used the 0 prefix instead. This is great because

1. an integer constant now always consists of a single token,
2. the parser can still tell right away it's got a constant,
3. the parser can immediately tell the base (0 is the same in both bases),
4. it's mathematically sane (00005 == 05), and
5. no precious special characters are needed (as in #123).

When C was created from B, the need for hexadecimal numbers arose (the PDP-11 had 16-bit words) and all of the points above were still valid. Since octals were still needed for other machines, 0x was arbitrarily chosen (00 was probably ruled out as awkward).

C# is a descendant of C, so it inherits the syntax.

Here are some other solutions. No need to use additional plugins.

Adding to jelovirt's answer, you can use number() to convert the value to a number, then round(), floor(), or ceiling() to get a whole integer.

Example

<xsl:variable name="MyValAsText" select="'5.14'"/>
<xsl:value-of select="number($MyValAsText) * 2"/> <!-- This outputs 10.28 -->
<xsl:value-of select="floor($MyValAsText)"/> <!-- outputs 5 -->
<xsl:value-of select="ceiling($MyValAsText)"/> <!-- outputs 6 -->
<xsl:value-of select="round($MyValAsText)"/> <!-- outputs 5 -->

I had the similar issue. The problem was in the passwords: the Keystore and private key used different passwords. (KeyStore explorer was used)

After creating Keystore with the same password as private key had the issue was resolved.

it seems as if it comes when u have an previous compiled version of your program running

To prevent the problem from occurring, you must perform a graceful shutdown of the server from the command line rather than powering off the server.

shutdown -h now

This will stop the running services before powering down the machine.

Based on Centos, an additional method for getting it back up again when you run into this problem is to move mysql.sock:

mv /var/lib/mysql/mysql.sock /var/lib/mysql/mysql.sock.bak

service mysqld start

Restarting the service creates a new entry called mqsql.sock

Using Java 8 stream API:

 String[] keys = new String[0];

// A map for keys and their count
Map<String, Long> keyCountMap = Arrays.stream(keys).
collect(Collectors.groupingBy(Function.identity(), Collectors.counting()));
int uniqueItemIdCount= keyCountMap.size();

"a"[0]

or

?a

Both would return their ASCII equivalent.

Use SET STATISTICS TIME ON

above your query.

Below near result tab you can see a message tab. There you can see the time.

On Mac OSX 10.11.5 this works fine:

grep -rli 'old-word' * | xargs -I@ sed -i '' 's/old-word/new-word/g' @

An enhanced for loop is just limiting the number of parameters inside the parenthesis.

for (int i = 0; i < myArray.length; i++) {
    System.out.println(myArray[i]);
}

Can be written as:

for (int myValue : myArray) {
    System.out.println(myValue);
}

You can simply assign the B to the new column , Like -

df['D'] = df['B']

Here is the answer for those of you who need a Boostrap 3 solution.

In bootstrap 3 use 'shown.bs.tab' instead of 'shown' in the next line

// tab
$('#rowTab a:first').tab('show');

$('a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
//show selected tab / active
 console.log ( $(e.target).attr('id') );
});

Facebook uses Bit.ly's services to shorten links from their site. While pages that have a username turns into "fb.me/<username>", other links associated with Facebook turns into "on.fb.me/*****". To you use the on.fb.me service, just use your Bit.ly account. Note that if you change the default link shortener on your Bit.ly account to j.mp from bit.ly this service won't work.

Install it by running

python setup.py install

Better yet, you can download from github. Install git via apt-get install git and then follow this steps:

git clone https://github.com/mwaskom/seaborn.git
cd seaborn
python setup.py install

Because your else isn't attached to anything. The if without braces only encompasses the single statement that immediately follows it.

if (choice==5)
{
    System.out.println("End of Game\n Thank you for playing with us!");
    break;
}
else
{
   System.out.println("Not a valid choice!\n Please try again...\n");
}

Not using braces is generally viewed as a bad practice because it can lead to the exact problems you encountered.

In addition, using a switch here would make more sense.

int choice;
boolean keepGoing = true;
while(keepGoing)
{
    System.out.println("---> Your choice: ");
    choice = input.nextInt();
    switch(choice)
    {
        case 1: 
            playGame();
            break;
        case 2: 
            loadGame();
            break;
        // your other cases
        // ...
        case 5: 
            System.out.println("End of Game\n Thank you for playing with us!");
            keepGoing = false;
            break;
        default:
            System.out.println("Not a valid choice!\n Please try again...\n");
     }
 }         

Note that instead of an infinite for loop I used a while(boolean), making it easy to exit the loop. Another approach would be using break with labels.

I had a similar problem with a different cause and therefore different solution. In my case, I actually had an error where a singleton object was having a member variable modified in a non-threadsafe way. In this case, following the accepted answers and circumventing the parallel testing would only hide the error that was actually revealed by the test. My solution, of course, is to fix the design so that I don't have this bad behavior in my code.

If you want to use devel or feature branch, or you haven’t published a certain package to the NPM registry, or you can’t because it’s a private module, then you can point to a git:// URI instead of a version number in your package.json:

"dependencies": {
   "public": "git://github.com/user/repo.git#ref",
   "private": "git+ssh://[email protected]:user/repo.git#ref"
}

The #ref portion is optional, and it can be a branch (like master), tag (like 0.0.1) or a partial or full commit id.

To iterate over all the key-value pairs in a table you can use pairs:

for k, v in pairs(arr) do
  print(k, v[1], v[2], v[3])
end

outputs:

pears   2   p   green
apples  0   a   red
oranges 1   o   orange

Edit: Note that Lua doesn't guarantee any iteration order for the associative part of the table. If you want to access the items in a specific order, retrieve the keys from arr and sort it. Then access arr through the sorted keys:

local ordered_keys = {}

for k in pairs(arr) do
    table.insert(ordered_keys, k)
end

table.sort(ordered_keys)
for i = 1, #ordered_keys do
    local k, v = ordered_keys[i], arr[ ordered_keys[i] ]
    print(k, v[1], v[2], v[3])
end

outputs:

  apples  a   red     5
  oranges o   orange  12
  pears   p   green   7

For longitudes use: Decimal(9,6), and latitudes use: Decimal(8,6)

You shouldn't be closing the serial port in Python between writing and reading. There is a chance that the port is still closed when the Arduino responds, in which case the data will be lost.

while running:  
    # Serial write section
    setTempCar1 = 63
    setTempCar2 = 37
    setTemp1 = str(setTempCar1)
    setTemp2 = str(setTempCar2)
    print ("Python value sent: ")
    print (setTemp1)
    ard.write(setTemp1)
    time.sleep(6) # with the port open, the response will be buffered 
                  # so wait a bit longer for response here

    # Serial read section
    msg = ard.read(ard.inWaiting()) # read everything in the input buffer
    print ("Message from arduino: ")
    print (msg)

The Python Serial.read function only returns a single byte by default, so you need to either call it in a loop or wait for the data to be transmitted and then read the whole buffer.

On the Arduino side, you should consider what happens in your loop function when no data is available.

void loop()
{
  // serial read section
  while (Serial.available()) // this will be skipped if no data present, leading to
                             // the code sitting in the delay function below
  {
    delay(30);  //delay to allow buffer to fill 
    if (Serial.available() >0)
    {
      char c = Serial.read();  //gets one byte from serial buffer
      readString += c; //makes the string readString
    }
  }

Instead, wait at the start of the loop function until data arrives:

void loop()
{
  while (!Serial.available()) {} // wait for data to arrive
  // serial read section
  while (Serial.available())
  {
    // continue as before

EDIT 2

Here's what I get when interfacing with your Arduino app from Python:

>>> import serial
>>> s = serial.Serial('/dev/tty.usbmodem1411', 9600, timeout=5)
>>> s.write('2')
1
>>> s.readline()
'Arduino received: 2\r\n'

So that seems to be working fine.

In testing your Python script, it seems the problem is that the Arduino resets when you open the serial port (at least my Uno does), so you need to wait a few seconds for it to start up. You are also only reading a single line for the response, so I've fixed that in the code below also:

#!/usr/bin/python
import serial
import syslog
import time

#The following line is for serial over GPIO
port = '/dev/tty.usbmodem1411' # note I'm using Mac OS-X


ard = serial.Serial(port,9600,timeout=5)
time.sleep(2) # wait for Arduino

i = 0

while (i < 4):
    # Serial write section

    setTempCar1 = 63
    setTempCar2 = 37
    ard.flush()
    setTemp1 = str(setTempCar1)
    setTemp2 = str(setTempCar2)
    print ("Python value sent: ")
    print (setTemp1)
    ard.write(setTemp1)
    time.sleep(1) # I shortened this to match the new value in your Arduino code

    # Serial read section
    msg = ard.read(ard.inWaiting()) # read all characters in buffer
    print ("Message from arduino: ")
    print (msg)
    i = i + 1
else:
    print "Exiting"
exit()

Here's the output of the above now:

$ python ardser.py

63

With regards to operator<< and operator>> there is no good reason to make these operators friends. It is true that they should not be member functions, but they don't need to be friends, either.

The best thing to do is create public print(ostream&) and read(istream&) functions. Then, write the operator<< and operator>> in terms of those functions. This gives the added benefit of allowing you to make those functions virtual, which provides virtual serialization.

The Python documentation provides the perfect solution for this which uses the built-in function dir.

You can just use dir(module_name) and then it will return a list of the functions within that module.

For example, dir(time) will return

['_STRUCT_TM_ITEMS', '__doc__', '__loader__', '__name__', '__package__', '__spec__', 'altzone', 'asctime', 'ctime', 'daylight', 'get_clock_info', 'gmtime', 'localtime', 'mktime', 'monotonic', 'monotonic_ns', 'perf_counter', 'perf_counter_ns', 'process_time', 'process_time_ns', 'sleep', 'strftime', 'strptime', 'struct_time', 'time', 'time_ns', 'timezone', 'tzname', 'tzset']

which is the list of functions the 'time' module contains.

Check out Pathname and in particular Pathname#exist?.

File and its FileTest module are perhaps simpler/more direct, but I find Pathname a nicer interface in general.

Your understanding is mostly correct. You use select_related when the object that you're going to be selecting is a single object, so OneToOneField or a ForeignKey. You use prefetch_related when you're going to get a "set" of things, so ManyToManyFields as you stated or reverse ForeignKeys. Just to clarify what I mean by "reverse ForeignKeys" here's an example:

class ModelA(models.Model):
    pass

class ModelB(models.Model):
    a = ForeignKey(ModelA)

ModelB.objects.select_related('a').all() # Forward ForeignKey relationship
ModelA.objects.prefetch_related('modelb_set').all() # Reverse ForeignKey relationship

The difference is that select_related does an SQL join and therefore gets the results back as part of the table from the SQL server. prefetch_related on the other hand executes another query and therefore reduces the redundant columns in the original object (ModelA in the above example). You may use prefetch_related for anything that you can use select_related for.

The tradeoffs are that prefetch_related has to create and send a list of IDs to select back to the server, this can take a while. I'm not sure if there's a nice way of doing this in a transaction, but my understanding is that Django always just sends a list and says SELECT ... WHERE pk IN (...,...,...) basically. In this case if the prefetched data is sparse (let's say U.S. State objects linked to people's addresses) this can be very good, however if it's closer to one-to-one, this can waste a lot of communications. If in doubt, try both and see which performs better.

Everything discussed above is basically about the communications with the database. On the Python side however prefetch_related has the extra benefit that a single object is used to represent each object in the database. With select_related duplicate objects will be created in Python for each "parent" object. Since objects in Python have a decent bit of memory overhead this can also be a consideration.

You can also make additions to this path with the PYTHONPATH environment variable at runtime, in addition to:

sys.path.append('/home/user/python-libs')

Recursive function :

function getElementInsideElement(baseElement, wantedElementID) {
    var elementToReturn;
    for (var i = 0; i < baseElement.childNodes.length; i++) {
        elementToReturn = baseElement.childNodes[i];
        if (elementToReturn.id == wantedElementID) {
            return elementToReturn;
        } else {
            return getElementInsideElement(elementToReturn, wantedElementID);
        }
    }
}

No, there is no built-in support for building strings. You have to use concatenation instead.

You can, of course, make an array of different parts of your string and then call join() on that array, but it then depends on how the join is implemented in the JavaScript interpreter you are using.

I made an experiment to compare the speed of str1+str2 method versus array.push(str1, str2).join() method. The code was simple:

var iIterations =800000;
var d1 = (new Date()).valueOf();
str1 = "";
for (var i = 0; i<iIterations; i++)
    str1 = str1 + Math.random().toString();
var d2 = (new Date()).valueOf();
log("Time (strings): " + (d2-d1));

var d3 = (new Date()).valueOf();
arr1 = [];
for (var i = 0; i<iIterations; i++)
    arr1.push(Math.random().toString());
var str2 = arr1.join("");
var d4 = (new Date()).valueOf();
log("Time (arrays): " + (d4-d3));

I tested it in Internet Explorer 8 and Firefox 3.5.5, both on a Windows 7 x64.

In the beginning I tested on small number of iterations (some hundred, some thousand items). The results were unpredictable (sometimes string concatenation took 0 milliseconds, sometimes it took 16 milliseconds, the same for array joining).

When I increased the count to 50,000, the results were different in different browsers - in Internet Explorer the string concatenation was faster (94 milliseconds) and join was slower(125 milliseconds), while in Firefox the array join was faster (113 milliseconds) than string joining (117 milliseconds).

Then I increased the count to 500'000. Now the array.join() was slower than string concatenation in both browsers: string concatenation was 937 ms in Internet Explorer, 1155 ms in Firefox, array join 1265 in Internet Explorer, and 1207 ms in Firefox.

The maximum iteration count I could test in Internet Explorer without having "the script is taking too long to execute" was 850,000. Then Internet Explorer was 1593 for string concatenation and 2046 for array join, and Firefox had 2101 for string concatenation and 2249 for array join.

Results - if the number of iterations is small, you can try to use array.join(), as it might be faster in Firefox. When the number increases, the string1+string2 method is faster.

UPDATE

I performed the test on Internet Explorer 6 (Windows XP). The process stopped to respond immediately and never ended, if I tried the test on more than 100,000 iterations. On 40,000 iterations the results were

Time (strings): 59175 ms
Time (arrays): 220 ms

This means - if you need to support Internet Explorer 6, choose array.join() which is way faster than string concatenation.

With SSL the encryption is at the transport level, so it takes place before a request is sent.

So everything in the request is encrypted.

You can do a workaround as below:

Create a shortcut for eclipse and right click on the short cut and go to properties of the shortcut.

In the target box update the string:

-vm "C:\Program Files\Java\jdk1.6.0_07\bin"

the path will change according to your java installed directory.

So after changing the target string will be something like below.

D:\adt-bundle-windows-x86-20131030\eclipse\eclipse.exe -vm "C:\Program Files\Java\jdk1.6.0_07\bin"

Click apply and try clicking the Eclipse shortcut.

Manually adding it as you have done is indeed one way of doing this, but there is a simpler method, and that is by simply telling pycharm that you want to add the src folder as a source root, and then adding the sources root to your python path.

This way, you don't have to hard code things into your interpreter's settings:

• Add src as a source content root:

• Then make sure to add add sources to your PYTHONPATH under:

  Preferences ~ Build, Execution, Deployment ~ Console ~ Python Console
  

• Now imports will be resolved:

This way, you can add whatever you want as a source root, and things will simply work. If you unmarked it as a source root however, you will get an error:

After all this don't forget to restart. In PyCharm menu select: File --> Invalidate Caches / Restart

First of all, you probably want to check for a DBNull not a regular Null.

Or you could look at the IsDBNull method

Actually what made this so confusing is that the Beanstalk people stand behind their very non-standard use of Staging (it comes before development in their diagram, and it's not a mistake!

iOS Status bar has only 2 options (black and white). You can try this in AppDelegate:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
    [[UIApplication sharedApplication] setStatusBarStyle: UIStatusBarStyleLightContent];
}

If at all anyone is looking to convert data in 1 variable that lies in 2 or 3 different lines like below

'Data1

Data2'

And you want to display data as 'Data1 Data2' then use below

select TRANSLATE ('Data1

Data2', ''||CHR(10), ' ') from dual;

it took me hrs to get the right output. Thanks to me I just saved you 1 or 2 hrs :)

If your data has changed every once,you will notice dont tracing the table.for example some table update id ([key]) using tigger.If you tracing ,you will get same id and get the issue.

If you have the proxies set up correctly, and still cannot reach the internet, it could be the DNS resolution. Check /etc/resolve.conf on the host Ubuntu VM. If it contains nameserver 127.0.1.1, that is wrong.

Run these commands on the host Ubuntu VM to fix it:

sudo vi /etc/NetworkManager/NetworkManager.conf
# Comment out the line `dns=dnsmasq` with a `#`

# restart the network manager service
sudo systemctl restart network-manager

cat /etc/resolv.conf

Now /etc/resolv.conf should have a valid value for nameserver, which will be copied by the docker containers.

Hmm, looks a little bizarre, try running it with the following annotation at the top of the class:

@RunWith(SpringJUnit4ClassRunner.class)
public class UserDaoTest {
}

and let me know how you get on with it.

Check that you have build automatically enabled as well. If you want to make sure your test classes are being compiled correctly clear out the Maven target folder (and any bin folder that Eclipse may be using). Are you using m2eclipse as well, as I find it to be a little problematic.

I faced this issue, and resolved this issue using getchar() to catch the ('\n') new char

Try

//adding data to session
//assuming the method below will return list of Products

var products=Db.GetProducts();

//Store the products to a session

Session["products"]=products;

//To get what you have stored to a session

var products=Session["products"] as List<Product>;

//to clear the session value

Session["products"]=null;

In Windows inorder to set

Step 1 : Right Click on MyComputer and click on properties .

Step 2 : Click on Advanced tab

Step 3: Click on Environment Variables

Step 4: Create a new class path for JAVA_HOME

Step 5: Enter the Variable name as JAVA_HOME and the value to your jdk bin path ie c:\Programfiles\Java\jdk-1.6\bin and

NOTE Make sure u start with .; in the Value so that it doesn't corrupt the other environment variables which is already set.

Step 6 : Follow the Above step and edit the Path in System Variables add the following ;c:\Programfiles\Java\jdk-1.6\bin in the value column.

Step 7 :Your are done setting up your environment variables for your Java , In order to test it go to command prompt and type

 java   

who will get a list of help doc

In order make sure whether compiler is setup Type in cmd

  javac

who will get a list related to javac

Hope this Helps !

After configuring this plug-in, running mvn package will produce two jars: one containing just the project classes, and a second fat jar with all dependencies with the suffix "-jar-with-dependencies".

if you want correct classpath setup at runtime then also add following plugin

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <configuration>
        <archive>
            <manifest>

            </manifest>
        </archive>
    </configuration>
</plugin>

For spring boot application use just following plugin (choose appropriate version of it)

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <configuration>
        <fork>true</fork>

First try to understand how Entity Framework Connection string works then you will get idea of what is wrong.

1. You have two different models, Entity and ModEntity
2. This means you have two different contexts, each context has its own Storage Model, Conceptual Model and mapping between both.
3. You have simply combined strings, but how does Entity's context will know that it has to pickup entity.csdl and ModEntity will pickup modentity.csdl? Well someone could write some intelligent code but I dont think that is primary role of EF development team.
4. Also machine.config is bad idea.
5. If web apps are moved to different machine, or to shared hosting environment or for maintenance purpose it can lead to problems.
6. Everybody will be able to access it, you are making it insecure. If anyone can deploy a web app or any .NET app on server, they get full access to your connection string including your sensitive password information.

Another alternative is, you can create your own constructor for your context and pass your own connection string and you can write some if condition etc to load defaults from web.config

Better thing would be to do is, leave connection strings as it is, give your application pool an identity that will have access to your database server and do not include username and password inside connection string.

If you need to create many zero filled arrays of different lengths during the execution of your code, the fastest way I've found to achieve this is to create a zero array once, using one of the methods mentioned on this topic, of a length which you know will never be exceeded, and then slice that array as necessary.

For example (using the function from the chosen answer above to initialize the array), create a zero filled array of length maxLength, as a variable visible to the code that needs zero arrays:

var zero = newFilledArray(maxLength, 0);

Now slice this array everytime you need a zero filled array of length requiredLength < maxLength:

zero.slice(0, requiredLength);

I was creating zero filled arrays thousands of times during execution of my code, this speeded up the process tremendously.

How about some attribute magic?

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, Inherited = true, AllowMultiple = false)]
public class MaxJsonSizeAttribute : ActionFilterAttribute
{
    // Default: 10 MB worth of one byte chars
    private int maxLength = 10 * 1024 * 1024;

    public int MaxLength
    {
        set
        {
            if (value < 0) throw new ArgumentOutOfRangeException("value", "Value must be at least 0.");

            maxLength = value;
        }
        get { return maxLength; }
    }

    public override void OnActionExecuted(ActionExecutedContext filterContext)
    {
        JsonResult json = filterContext.Result as JsonResult;
        if (json != null)
        {
            if (maxLength == 0)
            {
                json.MaxJsonLength = int.MaxValue;
            }
            else
            {
                json.MaxJsonLength = maxLength;
            }
        }
    }
}

Then you could either apply it globally using the global filter configuration or controller/action-wise.

Add your multiple columns with comma separations:

UPDATE settings SET postsPerPage = $postsPerPage, style= $style WHERE id = '1'

However, you're not sanitizing your inputs?? This would mean any random hacker could destroy your database. See this question: What's the best method for sanitizing user input with PHP?

Also, is style a number or a string? I'm assuming a string, so it would need to be quoted.

In jQuery 3 and perhaps earlier versions, the following simpler config also works for individual requests:

$.ajax(
        'https://foo.bar.com,
        {
            dataType: 'json',
            xhrFields: {
                withCredentials: true
            },
            success: successFunc
        }
    );

The full error I was getting in Firefox Dev Tools -> Network tab (in the Security tab for an individual request) was:

An error occurred during a connection to foo.bar.com.SSL peer was unable to negotiate an acceptable set of security parameters.Error code: SSL_ERROR_HANDSHAKE_FAILURE_ALERT

Try below code using RJSONIO in console

library(RJSONIO)
library(RCurl)


json_file = getURL("https://raw.githubusercontent.com/isrini/SI_IS607/master/books.json")

json_file2 = RJSONIO::fromJSON(json_file)

head(json_file2)

you could make them all #'s.

You would then need to add return false; to the end of any function that is called onclick of the anchor to not have the page jump up to the top.

It depends. You could

string.match(/^abc$/)

But that would not match the following string: 'the first 3 letters of the alphabet are abc. not abc123'

I think you would want to use \b (word boundaries):

var str = 'the first 3 letters of the alphabet are abc. not abc123';_x000D_
var pat = /\b(abc)\b/g;_x000D_
console.log(str.match(pat));

Live example: http://jsfiddle.net/uu5VJ/

If the former solution works for you, I would advise against using it.

That means you may have something like the following:

var strs = ['abc', 'abc1', 'abc2']
for (var i = 0; i < strs.length; i++) {
    if (strs[i] == 'abc') {
        //do something 
    }
    else {
        //do something else
    }
}

While you could use

if (str[i].match(/^abc$/g)) {
    //do something 
}

It would be considerably more resource-intensive. For me, a general rule of thumb is for a simple string comparison use a conditional expression, for a more dynamic pattern use a regular expression.

Under Project->Properties->Debug, you should see a box for Command line arguments (This is in C# 2010, but it should basically be the same place)

According to OpenCV cheat-sheet this can be done as follows:

IplImage* oldC0 = cvCreateImage(cvSize(320,240),16,1);
Mat newC = cvarrToMat(oldC0);

The cv::cvarrToMat function takes care of the conversion issues.

1-> Using File Default Config- Angular-cli comes from the ember-cli project. To run the application on specific port, create an .ember-cli file in the project root. Add your JSON config in there:

{ "port": 1337 }

2->Using Command Line Tool Run this command in Angular-Cli

ng serve --port 1234

To change the port number permanently:

Goto

Just one line : Update (thanks to @suther):

$array_without_empty_values = array_filter($array);

While @Eli is quite correct that there usually isn't much of a need to do it, it is possible. savefig takes a bbox_inches argument that can be used to selectively save only a portion of a figure to an image.

Here's a quick example:

import matplotlib.pyplot as plt
import matplotlib as mpl
import numpy as np

# Make an example plot with two subplots...
fig = plt.figure()
ax1 = fig.add_subplot(2,1,1)
ax1.plot(range(10), 'b-')

ax2 = fig.add_subplot(2,1,2)
ax2.plot(range(20), 'r^')

# Save the full figure...
fig.savefig('full_figure.png')

# Save just the portion _inside_ the second axis's boundaries
extent = ax2.get_window_extent().transformed(fig.dpi_scale_trans.inverted())
fig.savefig('ax2_figure.png', bbox_inches=extent)

# Pad the saved area by 10% in the x-direction and 20% in the y-direction
fig.savefig('ax2_figure_expanded.png', bbox_inches=extent.expanded(1.1, 1.2))

The full figure:

Area inside the second subplot:

Area around the second subplot padded by 10% in the x-direction and 20% in the y-direction:

Update will give you better performance with a queryset of more than one object, as it will make one database call per queryset.

However save is useful, as it is easy to override the save method in your model and add extra logic there. In my own application for example, I update a dates when other fields are changed.

Class myModel(models.Model): 
    name = models.CharField()
    date_created = models.DateField()

    def save(self):
        if not self.pk :
           ### we have a newly created object, as the db id is not set
           self.date_created = datetime.datetime.now()
        super(myModel , self).save()

Include Modernizr on your page and set your hover states like this instead:

html.no-touchevents .box:hover {
    background: blue;
}

It is impossible for both (?=foo) and (?=baz) to match at the same time. It would require the next character to be both f and b simultaneously which is impossible.

Perhaps you want this instead:

(?=.*foo)(?=.*baz)

This says that foo must appear anywhere and baz must appear anywhere, not necessarily in that order and possibly overlapping (although overlapping is not possible in this specific case because the letters themselves don't overlap).

I faced the same error with my Visual Studio Team Services account (formerly Visual Studio Online, Team Foundation Service).

I simply entered the credentials using the VS 2013 "Connect to Team Foundation Server" Window, and then connected it to the Visual Studio Team Services Team Project. It worked this way.

I think you need the Web Tools Platform package for this. Not very sure though. You can add it to your current eclipse through Help > install new software.

Then add the software repository site location for WTP for your version of eclipse. This is how you can install plugins in eclipse.

Uninstall:

mysql> uninstall plugin validate_password;

An uninstalled plugin is not displayed by show plugins;

Install:

mysql> install plugin validate_password SONAME 'validate_password.so';

Disabled by configuration:

[mysqld]
validate_password = OFF

A plugin can be disabled by configuration only if installed.

The R file can't be generated if your layout contains errors. If your res folder is empty, then it's safe to assume that there's no res/layout folder with any layouts in it, but your activity is probably calling setContentView and not finding anything -- that qualifies as a problem with your layout.

It's implementation-specific, but in practice the rule (in the absence of #pragma pack or the like) is:

• Struct members are stored in the order they are declared. (This is required by the C99 standard, as mentioned here earlier.)
• If necessary, padding is added before each struct member, to ensure correct alignment.
• Each primitive type T requires an alignment of sizeof(T) bytes.

So, given the following struct:

struct ST
{
   char ch1;
   short s;
   char ch2;
   long long ll;
   int i;
};

• ch1 is at offset 0
• a padding byte is inserted to align...
• s at offset 2
• ch2 is at offset 4, immediately after s
• 3 padding bytes are inserted to align...
• ll at offset 8
• i is at offset 16, right after ll
• 4 padding bytes are added at the end so that the overall struct is a multiple of 8 bytes. I checked this on a 64-bit system: 32-bit systems may allow structs to have 4-byte alignment.

So sizeof(ST) is 24.

It can be reduced to 16 bytes by rearranging the members to avoid padding:

struct ST
{
   long long ll; // @ 0
   int i;        // @ 8
   short s;      // @ 12
   char ch1;     // @ 14
   char ch2;     // @ 15
} ST;

Remove some of your textarea class like

<textarea name="Address" rows="3" class="input-text full-width" placeholder="Your Address" ></textarea>

To

<textarea name="Address" rows="3" class="full-width" placeholder="Your Address" ></textarea>

It's dependent on your template (Purchased Template). The developer has included some JavaScript to get the value from correct object on UI, but class like input-text just finds only $('input[type=text]'), that's why.

@Jacob already showed you how to use the Gaussian filter in Matlab, so I won't repeat that.

I would choose filter size to be about 3*sigma in each direction (round to odd integer). Thus, the filter decays to nearly zero at the edges, and you won't get discontinuities in the filtered image.

The choice of sigma depends a lot on what you want to do. Gaussian smoothing is low-pass filtering, which means that it suppresses high-frequency detail (noise, but also edges), while preserving the low-frequency parts of the image (i.e. those that don't vary so much). In other words, the filter blurs everything that is smaller than the filter.

If you're looking to suppress noise in an image in order to enhance the detection of small features, for example, I suggest to choose a sigma that makes the Gaussian just slightly smaller than the feature.

This error comes when using the following command in Windows. You can simply run the following command by removing the dot '.' and the slash '/'.
