For those who like Debian and prepackaged Java:

sudo mkdir /usr/share/ca-certificates/test/  # don't mess with other certs
sudo cp ~/tmp/test.loc.crt /usr/share/ca-certificates/test/
sudo dpkg-reconfigure --force ca-certificates  # check your cert in curses GUI!
sudo update-ca-certificates --fresh --verbose

Don't forget to check /etc/default/cacerts for:

# enable/disable updates of the keystore /etc/ssl/certs/java/cacerts
cacerts_updates=yes

To remove cert:

sudo rm /usr/share/ca-certificates/test/test.loc.crt
sudo rm /etc/ssl/certs/java/cacerts
sudo update-ca-certificates --fresh --verbose

You want to use the csv module that is part of the python language and you should use Django's get_or_create method

 with open(path) as f:
        reader = csv.reader(f)
        for row in reader:
            _, created = Teacher.objects.get_or_create(
                first_name=row[0],
                last_name=row[1],
                middle_name=row[2],
                )
            # creates a tuple of the new object or
            # current object and a boolean of if it was created

In my example the model teacher has three attributes first_name, last_name and middle_name.

Django documentation of get_or_create method

Use:

$("#id option").each(function()
{
    // Add $(this).val() to your list
});

.each() | jQuery API Documentation

Not exactly. You can't get two Streams out of one; this doesn't make sense -- how would you iterate over one without needing to generate the other at the same time? A stream can only be operated over once.

However, if you want to dump them into a list or something, you could do

stream.forEach((x) -> ((x == 0) ? heads : tails).add(x));

The csv.DictReader object exposes an attribute called fieldnames, and that is what you'd use. Here's example code, followed by input and corresponding output:

import csv
file = "/path/to/file.csv"
with open(file, mode='r', encoding='utf-8') as f:
    reader = csv.DictReader(f, delimiter=',')
    for row in reader:
        print([col + '=' + row[col] for col in reader.fieldnames])

Input file contents:

col0,col1,col2,col3,col4,col5,col6,col7,col8,col9
00,01,02,03,04,05,06,07,08,09

You need to force a clear:both before the #main_content div is closed. I would probably move the <br class="clear" />; into the #main_content div and set the CSS to be:

.clear { clear: both; }

Update: This question still gets a fair amount of traffic, so I wanted to update the answer with a modern alternative using a new layout mode in CSS3 called Flexible boxes or Flexbox:

body {_x000D_
  margin: 0;_x000D_
}_x000D_
_x000D_
.flex-container {_x000D_
  display: flex;_x000D_
  flex-direction: column;_x000D_
  min-height: 100vh;_x000D_
}_x000D_
_x000D_
header {_x000D_
  background-color: #3F51B5;_x000D_
  color: #fff;_x000D_
}_x000D_
_x000D_
section.content {_x000D_
  flex: 1;_x000D_
}_x000D_
_x000D_
footer {_x000D_
  background-color: #FFC107;_x000D_
  color: #333;_x000D_
}

<div class="flex-container">_x000D_
  <header>_x000D_
    <h1>_x000D_
     Header   _x000D_
    </h1>_x000D_
  </header>_x000D_
_x000D_
  <section class="content">_x000D_
    Content_x000D_
  </section>_x000D_
_x000D_
  <footer>_x000D_
    <h4>_x000D_
      Footer_x000D_
    </h4>_x000D_
  </footer>_x000D_
</div>

Most modern browsers currently support Flexbox and viewport units, but if you have to maintain support for older browsers, make sure to check compatibility for the specific browser version.

Try this

var d = new Date();
d.setDate(d.getDate() - 1);

To print the address of a variable, you need to use the %p format. %d is for signed integers. For example:

#include<stdio.h>

void main(void)
{
  int a;

  printf("Address is %p:",&a);
}

To extract only the filename from the path, you can do the following:

varFileName = Mid(fDialog.SelectedItems(1), InStrRev(fDialog.SelectedItems(1), "\") + 1, Len(fDialog.SelectedItems(1)))

Connections have a close method as specified in PEP-249 (Python Database API Specification v2.0):

import pyodbc
conn = pyodbc.connect('DRIVER=MySQL ODBC 5.1 driver;SERVER=localhost;DATABASE=spt;UID=who;PWD=testest') 

csr = conn.cursor()  
csr.close()
conn.close()     #<--- Close the connection

Since the pyodbc connection and cursor are both context managers, nowadays it would be more convenient (and preferable) to write this as:

import pyodbc
conn = pyodbc.connect('DRIVER=MySQL ODBC 5.1 driver;SERVER=localhost;DATABASE=spt;UID=who;PWD=testest') 
with conn:
    crs = conn.cursor()
    do_stuff
    # conn.commit() will automatically be called when Python leaves the outer `with` statement
    # Neither crs.close() nor conn.close() will be called upon leaving the `with` statement!! 

See https://github.com/mkleehammer/pyodbc/issues/43 for an explanation for why conn.close() is not called.

Note that unlike the original code, this causes conn.commit() to be called. Use the outer with statement to control when you want commit to be called.

Also note that regardless of whether or not you use the with statements, per the docs,

Connections are automatically closed when they are deleted (typically when they go out of scope) so you should not normally need to call [conn.close()], but you can explicitly close the connection if you wish.

and similarly for cursors (my emphasis):

Cursors are closed automatically when they are deleted (typically when they go out of scope), so calling [csr.close()] is not usually necessary.

Compare getApplication() and getApplicationContext().

getApplication returns an Application object which will allow you to manage your global application state and respond to some device situations such as onLowMemory() and onConfigurationChanged().

getApplicationContext returns the global application context - the difference from other contexts is that for example, an activity context may be destroyed (or otherwise made unavailable) by Android when your activity ends. The Application context remains available all the while your Application object exists (which is not tied to a specific Activity) so you can use this for things like Notifications that require a context that will be available for longer periods and independent of transient UI objects.

I guess it depends on what your code is doing whether these may or may not be the same - though in normal use, I'd expect them to be different.

you may use this - https://github.com/chanakyachatterjee/JSLightGrid ..JSLightGrid. have a look.. I found this one really very useful. Good performance, very light weight, all important browser friendly and fluid in itself, so you don't really need bootstrap for the grid.

Maybe this was just a fluke but the one time I had this error, I simply had to kill all javaw.exe processes that were running in the background. The executable JAR worked after that.

Here is a way to remove a specific commit id knowing only the commit id you would like to remove.

git rebase --onto commit-id^ commit-id

Note that this actually removes the change that was introduced by the commit.

You can pass the element into the function <input type="button" value="mybutton1" onclick="dosomething(this)">test by passing this. Then in the function you can access the value like this:

function dosomething(element) {
  console.log(element.value);
}

note - lepl is no longer supported, sorry (you're welcome to use it, and i think the code below works, but it's not going to get updates).

rfc 3696 http://www.faqs.org/rfcs/rfc3696.html defines how to do this (for http urls and email). i implemented its recommendations in python using lepl (a parser library). see http://acooke.org/lepl/rfc3696.html

to use:

> easy_install lepl
...
> python
...
>>> from lepl.apps.rfc3696 import HttpUrl
>>> validator = HttpUrl()
>>> validator('google')
False
>>> validator('http://google')
False
>>> validator('http://google.com')
True

you can also use pure js to accomplish this like the old ways with jquery

try this if you want a simple way

 document.getElementById("myID").classList.add("show-example");

I have set up Volley as a separate Project. That way its not tied to any project and exist independently.

I also have a Nexus server (Internal repo) setup so I can access volley as
compile 'com.mycompany.volley:volley:1.0.4' in any project I need.

Any time I update Volley project, I just need to change the version number in other projects.

I feel very comfortable with this approach.

Use \vspace{-\topsep} before \begin{itemize}.

Use \setlength{\parskip}{0pt} \setlength{\itemsep}{0pt plus 1pt} after \begin{itemize}.

And for the space after the list, use \vspace{-\topsep} after \end{itemize}.

\vspace{-\topsep}
\begin{itemize}
  \setlength{\parskip}{0pt}
  \setlength{\itemsep}{0pt plus 1pt}
  \item ...
  \item ...
\end{itemize}
\vspace{-\topsep}

Apart from fixing the imports, do a fresh maven clean compile -U. Note the -U option, that brings in new dependencies which sometimes the editor has hard time with. Let the compilation fail due to un-imported classes, but at least you have an option to import them after the maven command.

Just doing Maven->Reimport from Intellij did not work for me.

Easy and handy commands

To delete all images

docker rmi $(docker images -a)

To delete containers which are in exited state

docker rm $(docker ps -a -f status=exited -q)

To delete containers which are in created state

docker rm $(docker ps -a -f status=created -q)

NOTE: Remove all the containers then remove the images

In Angular / Ionic / VueJS -- I just came up with a simple method of:

stripNaN(txt: any) {
    return txt.toString().replace(/[^a-zA-Z0-9]/g, "");
}

Usage on the view:

<a [href]="'tel:'+stripNaN(single.meta['phone'])" [innerHTML]="stripNaN(single.meta['phone'])"></a>

If you follow your link, it tells you that the error results from the $injector not being able to resolve your dependencies. This is a common issue with angular when the javascript gets minified/uglified/whatever you're doing to it for production.

The issue is when you have e.g. a controller;

angular.module("MyApp").controller("MyCtrl", function($scope, $q) {
  // your code
})

The minification changes $scope and $q into random variables that doesn't tell angular what to inject. The solution is to declare your dependencies like this:

angular.module("MyApp")
  .controller("MyCtrl", ["$scope", "$q", function($scope, $q) {
  // your code
}])

That should fix your problem.

Just to re-iterate, everything I've said is at the link the error message provides to you.

Method #1. Here is the simple function to test if the string contains HTML data:

function isHTML(str) {
  var a = document.createElement('div');
  a.innerHTML = str;

  for (var c = a.childNodes, i = c.length; i--; ) {
    if (c[i].nodeType == 1) return true; 
  }

  return false;
}

The idea is to allow browser DOM parser to decide if provided string looks like an HTML or not. As you can see it simply checks for ELEMENT_NODE (nodeType of 1).

I made a couple of tests and looks like it works:

isHTML('<a>this is a string</a>') // true
isHTML('this is a string')        // false
isHTML('this is a <b>string</b>') // true

This solution will properly detect HTML string, however it has side effect that img/vide/etc. tags will start downloading resource once parsed in innerHTML.

Method #2. Another method uses DOMParser and doesn't have loading resources side effects:

function isHTML(str) {
  var doc = new DOMParser().parseFromString(str, "text/html");
  return Array.from(doc.body.childNodes).some(node => node.nodeType === 1);
}

<sub>Notes:
1. Array.from is ES2015 method, can be replaced with [].slice.call(doc.body.childNodes).
2. Arrow function in some call can be replaced with usual anonymous function.</sub>

socket.disconnect() can be used only on the client side, not on the server side.

Client.emit('disconnect') triggers the disconnection event on the server, but does not effectively disconnect the client. The client is not aware of the disconnection.

So the question remain : how to force a client to disconnect from server side ?

Use delegate and event.target. delegate takes advantage of the event bubbling by letting one element listen for, and handle, events on child elements. target is the jQ-normalized property of the event object representing the object from which the event originated.

$(document).delegate('*', 'click', function (event) {
    // event.target is the element
    // $(event.target).text() gets its text
});

Here's a one-line solution with mapfile:

$ mapfile -d $'\0' -t arr < <(printf '%s\0' "${arr[@]}" | grep -Pzv "<regexp>")

Example:

$ arr=("Adam" "Bob" "Claire"$'\n'"Smith" "David" "Eve" "Fred")

$ echo "Size: ${#arr[*]} Contents: ${arr[*]}"

Size: 6 Contents: Adam Bob Claire
Smith David Eve Fred

$ mapfile -d $'\0' -t arr < <(printf '%s\0' "${arr[@]}" | grep -Pzv "^Claire\nSmith$")

$ echo "Size: ${#arr[*]} Contents: ${arr[*]}"

Size: 5 Contents: Adam Bob David Eve Fred

This method allows for great flexibility by modifying/exchanging the grep command and doesn't leave any empty strings in the array.

The error is coming as your query is getting formed as

SELECT * FROM Employ where number = parseInt(val);

I dont know which DB you are using but no DB will understand parseInt.

What you can do is use a variable say temp and store the value of parseInt(val) in temp variable and make the query as

SELECT * FROM Employ where number = temp;

I think you missed a equal sign at:

Cursor c = ourDatabase.query(DATABASE_TABLE, column, KEY_ROWID + "" + l, null, null, null, null);  

Change to:

Cursor c = ourDatabase.query(DATABASE_TABLE, column, KEY_ROWID + " = " + l, null, null, null, null); 

Update

I just stumbled on this bug report:

https://bugs.launchpad.net/ubuntu/+source/ca-certificates-java/+bug/1396760

It appears to be the cause of our problems here. Something with ca-certificates-java encountering an error and not fully populating cacerts. For me, this started happening after I upgraded to 15.10 and this bug probably occurred during that process.

The workaround is to execute the following command:

sudo /var/lib/dpkg/info/ca-certificates-java.postinst configure

If you check the contents of the keystore (as in my original answer), you'll now see a whole bunch more, including the needed DigiCert Global Root CA.

If you went through the process in my original answer, you can clean up the key we added by running this command (assuming you did not specify a different alias):

sudo keytool -delete -alias mykey -keystore /etc/ssl/certs/java/cacerts

Maven will now work fine.

Original Answer

I'd just like to expand on Andy's answer about adding the certificate and specifying a keystore. That got me started, and combined with information elsewhere I was able to understand the problem and find another (better?) solution.

Andy's answer specifies a new keystore with the Maven cert specifically. Here, I'm going a bit more broad and adding the root certificate to the default java truststore. This allows me to use mvn (and other java stuff) without specifying a keystore.

For reference my OS is Ubuntu 15.10 with Maven 3.3.3.

Basically, the default java truststore in this setup does not trust the root certificate of the Maven repo (DigiCert Global Root CA), so it needs to be added.

I found it here and downloaded:

https://www.digicert.com/digicert-root-certificates.htm

Then I found the default truststore location, which resides here:

/etc/ssl/certs/java/cacerts

You can see what certs are currently in there by running this command:

keytool -list -keystore /etc/ssl/certs/java/cacerts

When prompted, the default keystore password is "changeit" (but nobody ever does).

In my setup, the fingerprint of "DigiCert Global Root CA" did not exist (DigiCert calls it "thumbprint" in the link above). So here's how to add it:

sudo keytool -import -file DigiCertGlobalRootCA.crt -keystore /etc/ssl/certs/java/cacerts

This should prompt if you trust the cert, say yes.

Use keytool -list again to verify that the key exists. I didn't bother to specify an alias (-alias), so it ended up like this:

mykey, Dec 2, 2015, trustedCertEntry, Certificate fingerprint (SHA1): A8:98:5D:3A:65:E5:E5:C4:B2:D7:D6:6D:40:C6:DD:2F:B1:9C:54:36

Then I was able to run mvn commands as normal, no need to specify keystore.

I had this problem because we where using a DNS name from an old server, ponting to a new server. Using the newserver\inst1 address, worked. both newserver\inst1 and oldserver\inst1 pointed to the same IP.

c is a double variable, but the value being assigned to it is an int value because it results from the division of two ints, which gives you "integer division" (dropping the remainder). So what happens in the line c=a/b is

1. a/b is evaluated, creating a temporary of type int
2. the value of the temporary is assigned to c after conversion to type double.

The value of a/b is determined without reference to its context (assignment to double).

It can't parse that string because "UTC" is not a valid time zone designator.

UTC time is denoted by adding a 'Z' to the end of the time string, so your parsing code should look like this:

DateTime.Parse("Tue, 1 Jan 2008 00:00:00Z");

From the Wikipedia article on ISO 8601

If the time is in UTC, add a 'Z' directly after the time without a space. 'Z' is the zone designator for the zero UTC offset. "09:30 UTC" is therefore represented as "09:30Z" or "0930Z". "14:45:15 UTC" would be "14:45:15Z" or "144515Z".

UTC time is also known as 'Zulu' time, since 'Zulu' is the NATO phonetic alphabet word for 'Z'.

I had the same issue , I am using eclipse, just in case others experience the same issue:
In eclipse double click the tomcat server,
stop the server
untick the "server modules without publishing"
start the server.

Use %0A (URL encoding) instead of \n (C encoding).

if you want to get the first N elements and also remove it from the array, you can use array_splice() (note the 'p' in "splice"):

http://docs.php.net/manual/da/function.array-splice.php

use it like so: $array_without_n_elements = array_splice($old_array, 0, N)

If using Visual Code one option is to add this to the settings.json file:

"eslint.options": {
    "useEslintrc": false,
    "parserOptions": {
        "ecmaVersion": 2017
    },
    "env": {
        "es6": true
    }
}

In Sql the with statement specifies a temporary named result set, known as a common table expression (CTE). It can be used for recursive queries, but in this case, it specifies as subset. If mysql allows for subselectes i would try

select t1.* 
from  (
            SELECT  article.*, 
                    userinfo.*, 
                    category.* 
            FROM    question INNER JOIN 
                    userinfo ON userinfo.user_userid=article.article_ownerid INNER JOIN category ON article.article_categoryid=category.catid
            WHERE   article.article_isdeleted = 0
     ) t1
ORDER BY t1.article_date DESC Limit 1, 3

Try the following:

List<Map<String, ArrayList<String>>> mapList = 
    new ArrayList<Map<String, ArrayList<String>>>();
mapList.add(map);

If your list must be of type List<HashMap<String, ArrayList<String>>>, then declare your map variable as a HashMap and not a Map.

The easiest way to do this is:

1. Create an App_GlobalResources system folder and add a resource file to it e.g. Messages.resx
2. Create your entries in the resource file e.g. ErrorMsg = This is an error.
3. Then to access that entry: string errormsg = Resources.Messages.ErrorMsg

Activation by system properties can be done as follows

<activation>
    <property>
        <name>foo</name>
        <value>bar</value>
    </property>
</activation>

And run the mvn build with -D to set system property

mvn clean install -Dfoo=bar

This method also helps select profiles in transitive dependency of project artifacts.

array1.equals(array2) is the same as array1 == array2, i.e. is it the same array. As @alf points out it's not what most people expect.

Arrays.equals(array1, array2) compares the contents of the arrays.

Similarly array.toString() may not be very useful and you need to use Arrays.toString(array).

You can use the following:

import json

 with open('<yourFile>.json', 'r') as JSON:
       json_dict = json.load(JSON)

 # Now you can use it like dictionary
 # For example:

 print(json_dict["username"])

i found something in the browser side itself.

Try this steps. here i have been mentioned the Steps to disable the Header and footer in all the three major browsers.

Chrome Click the Menu icon in the top right corner of the browser. Click Print. Uncheck Headers and Footers under the Options section.

Firefox Click Firefox in the top left corner of the browser. Place your mouse over Print, the click Page Setup. Click the Margins & Header/Footer tab. Change each value under Headers & Footers to --blank--.

Internet Explorer Click the Gear icon in the top right corner of the browser. Place your mouse over Print, then click Page Setup. Change each value under Headers and Footers to -Empty-.

Zookeeper is just a Java process and when you start a Zookeeper instance it runs a org.apache.zookeeper.server.quorum.QuorumPeerMain class. So you can check for a running Zookeeper like this:

jps -l | grep zookeeper

or even like this:

jps | grep Quorum

The first answer is good and gives some structural answers, but another approach is to think about what you're doing. Modules are about providing methods that you can use across multiple classes - think about them as "libraries" (as you would see in a Rails app). Classes are about objects; modules are about functions.

For example, authentication and authorization systems are good examples of modules. Authentication systems work across multiple app-level classes (users are authenticated, sessions manage authentication, lots of other classes will act differently based on the auth state), so authentication systems act as shared APIs.

You might also use a module when you have shared methods across multiple apps (again, the library model is good here).

This is how I understood it:

In Object oriented programming, we have something called classes. What are they for? They are to store some state and to store some methods to change that state i.e., they are encapsulating state and its methods.

It(class) does not care about the visibility of its own or of its contents. If we choose to hide the state or some methods, it is information hiding.

Now, take the scenario of an inheritance. We have a base class and a couple of derived (inherited) classes. So, what is the base class doing here? It is abstracting out some things from the derived classes.

All of them are different, right? But, we mix them up to write good object oriented programs. Hope it helps :)

I've found a solution through configuring the Spring container, but it's still not exactly what I wanted.

I rolled back to Spring 3.0.5, removed and in it's place I changed my config file to:

    <bean
    class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
    <property name="messageConverters">
        <list>
            <bean
                class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
                <property name="objectMapper" ref="jacksonObjectMapper" />
            </bean>
        </list>
    </property>
</bean>


<bean id="jacksonObjectMapper" class="org.codehaus.jackson.map.ObjectMapper" />
<bean id="jacksonSerializationConfig" class="org.codehaus.jackson.map.SerializationConfig"
    factory-bean="jacksonObjectMapper" factory-method="getSerializationConfig" />
<bean
    class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
    <property name="targetObject" ref="jacksonSerializationConfig" />
    <property name="targetMethod" value="setSerializationInclusion" />
    <property name="arguments">
        <list>
            <value type="org.codehaus.jackson.map.annotate.JsonSerialize.Inclusion">NON_NULL</value>
        </list>
    </property>
</bean>

This is of course similar to responses given in other questions e.g.

configuring the jacksonObjectMapper not working in spring mvc 3

The important thing to note is that mvc:annotation-driven and AnnotationMethodHandlerAdapter cannot be used in the same context.

I'm still unable to get it working with Spring 3.1 and mvc:annotation-driven though. A solution that uses mvc:annotation-driven and all the benefits that accompany it would be far better I think. If anyone could show me how to do this, that would be great.

You can use escape sequences, if your terminal supports it. For example:

echo \[\033[32m\]Hello, \[\033[36m\]colourful \[\033[33mworld!\033[0m\]

I think you are forgetting about the border. Having a one-pixel-wide border on the Div will take away two pixels of total length. Therefore it will appear as though the div is two pixels shorter than it actually is.

Convert your x-axis data from text to datetime.datetime, use datetime.strptime:

>>> from datetime import datetime
>>> datetime.strptime("2012-may-31 19:00", "%Y-%b-%d %H:%M")
 datetime.datetime(2012, 5, 31, 19, 0)

This is an example of how to plot data once you have an array of datetimes:

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

x = np.array([datetime.datetime(2013, 9, 28, i, 0) for i in range(24)])
y = np.random.randint(100, size=x.shape)

plt.plot(x,y)
plt.show()

This is how I did it:

curl -v \
  --key ./admin-key.pem \
  --cert ./admin.pem \
  https://xxxx/api/v1/

Just do not do it. Asking for something's type is wrong in itself. Instead use polymorphism. Find or if necessary define by yourself the method that does what you want for any possible type of input and just call it without asking about anything. If you need to work with built-in types or types defined by a third-party library, you can always inherit from them and use your own derivatives instead. Or you can wrap them inside your own class. This is the object-oriented way to resolve such problems.

If you insist on checking exact type and placing some dirty ifs here and there, you can use __class__ property or type function to do it, but soon you will find yourself updating all these ifs with additional cases every two or three commits. Doing it the OO way prevents that and lets you only define a new class for a new type of input instead.

apache commons lang has a class SystemUtils.java you can use :

SystemUtils.IS_OS_LINUX
SystemUtils.IS_OS_WINDOWS

If you are using a JAX-WS implementation for your client, such as Metro Web Services, the following code shows how to pass username and password in the HTTP headers:

 MyService port = new MyService();
 MyServiceWS service = port.getMyServicePort();

 Map<String, List<String>> credentials = new HashMap<String,List<String>>();

 credentials.put("username", Collections.singletonList("username"));
 credentials.put("password", Collections.singletonList("password"));

 ((BindingProvider)service).getRequestContext().put(MessageContext.HTTP_REQUEST_HEADERS, credentials);

Then subsequent calls to the service will be authenticated. Beware that the password is only encoded using Base64, so I encourage you to use other additional mechanism like client certificates to increase security.

I agree with Corey, urllib2 is more complete than urllib and should likely be the module used if you want to do more complex things, but to make the answers more complete, urllib is a simpler module if you want just the basics:

import urllib
response = urllib.urlopen('http://www.example.com/sound.mp3')
mp3 = response.read()

Will work fine. Or, if you don't want to deal with the "response" object you can call read() directly:

import urllib
mp3 = urllib.urlopen('http://www.example.com/sound.mp3').read()

assign is what you are looking for.

assign("x", 5)

x
[1] 5

but buyer beware.

.project

When a project is created in the workspace, a project description file is automatically generated that describes the project. The sole purpose of this file is to make the project self-describing, so that a project that is zipped up or released to a server can be correctly recreated in another workspace.

.classpath

Classpath specifies which Java source files and resource files in a project are considered by the Java builder and specifies how to find types outside of the project. The Java builder compiles the Java source files into the output folder and also copies the resources into it.

If you're on Linux, seriously consider just using the g_file_get_contents function from glib. It handles all the code for loading a file, allocating memory, and handling errors.

Razor is a view engine for ASP.NET MVC, and also a template engine. Razor code and ASP.NET inline code (code mixed with markup) both get compiled first and get turned into a temporary assembly before being executed. Thus, just like C# and VB.NET both compile to IL which makes them interchangable, Razor and Inline code are both interchangable.

Therefore, it's more a matter of style and interest. I'm more comfortable with razor, rather than ASP.NET inline code, that is, I prefer Razor (cshtml) pages to .aspx pages.

Imagine that you want to get a Human class, and render it. In cshtml files you write:

<div>Name is @Model.Name</div>

While in aspx files you write:

<div>Name is <%= Human.Name %></div>

As you can see, @ sign of razor makes mixing code and markup much easier.

Try using this:

$('#searchField').val('');

PS N:\> (measure-command {gdr -psprovider 'filesystem'|%{$_.name}|out-host}).totalmilliseconds

Without filtering properties, on my test system, 4319.4196ms to 1777.7237ms. Unless I need a PS-Drive object returned, I'll stick with WMI.

You have to use the NotifyIcon control from System.Windows.Forms, or alternatively you can use the Notify Icon API provided by Windows API. WPF Provides no such equivalent, and it has been requested on Microsoft Connect several times.

I have code on GitHub which uses System.Windows.Forms NotifyIcon Component from within a WPF application, the code can be viewed at https://github.com/wilson0x4d/Mubox/blob/master/Mubox.QuickLaunch/AppWindow.xaml.cs

Here are the summary bits:

Create a WPF Window with ShowInTaskbar=False, and which is loaded in a non-Visible State.

At class-level:

private System.Windows.Forms.NotifyIcon notifyIcon = null;

During OnInitialize():

notifyIcon = new System.Windows.Forms.NotifyIcon();
notifyIcon.Click += new EventHandler(notifyIcon_Click);
notifyIcon.DoubleClick += new EventHandler(notifyIcon_DoubleClick);
notifyIcon.Icon = IconHandles["QuickLaunch"];

During OnLoaded():

notifyIcon.Visible = true;

And for interaction (shown as notifyIcon.Click and DoubleClick above):

void notifyIcon_Click(object sender, EventArgs e)
{
    ShowQuickLaunchMenu();
}

From here you can resume the use of WPF Controls and APIs such as context menus, pop-up windows, etc.

It's that simple. You don't exactly need a WPF Window to host to the component, it's just the most convenient way to introduce one into a WPF App (as a Window is generally the default entry point defined via App.xaml), likewise, you don't need a WPF Wrapper or 3rd party control, as the SWF component is guaranteed present in any .NET Framework installation which also has WPF support since it's part of the .NET Framework (which all current and future .NET Framework versions build upon.) To date, there is no indication from Microsoft that SWF support will be dropped from the .NET Framework anytime soon.

Hope that helps.

It's a little cheese that you have to use a pre-3.0 Framework Component to get a tray-icon, but understandably as Microsoft has explained it, there is no concept of a System Tray within the scope of WPF. WPF is a presentation technology, and Notification Icons are an Operating System (not a "Presentation") concept.

If you want to use the value of the email input somewhere else on the same page, for example to do some sort of validation, you could use JavaScript. First I would assign an "id" attribute to your email textbox:

<input type="text" name="email" id="email"/>

and then I would retrieve the value with JavaScript:

var email = document.getElementById('email').value;

From there, you can do additional processing on the value of 'email'.

In Java, an initializer with the declaration means the field is always initialized the same way, regardless of which constructor is used (if you have more than one) or the parameters of your constructors (if they have arguments), although a constructor might subsequently change the value (if it is not final). So using an initializer with a declaration suggests to a reader that the initialized value is the value that the field has in all cases, regardless of which constructor is used and regardless of the parameters passed to any constructor. Therefore use an initializer with the declaration only if, and always if, the value for all constructed objects is the same.

You can use the synchronizedCollection/List method in java.util.Collection to get a thread-safe collection from a non-thread-safe one.

SELECT *
FROM
(
SELECT [Period], [Account], [Value]
FROM TableName
) AS source
PIVOT
(
    MAX([Value])
    FOR [Period] IN ([2000], [2001], [2002])
) as pvt

Another way,

SELECT ACCOUNT,
      MAX(CASE WHEN Period = '2000' THEN Value ELSE NULL END) [2000],
      MAX(CASE WHEN Period = '2001' THEN Value ELSE NULL END) [2001],
      MAX(CASE WHEN Period = '2002' THEN Value ELSE NULL END) [2002]
FROM tableName
GROUP BY Account

I had this problem and the problem was bootstrap.js wasn't load in Yii2 framework.First check is jquery loaded in inspect and then check bootstrap.js is loaded?If you used any tooltip Popper.js is needed before bootsrap.js.

Here are the steps to do it correctly:

1. First of all, declare an instance of TextView in your MainActivity.java as follows:

   TextView mTextView;
   

2. Set some text DYNAMICALLY(if you want) as follows:

   mTextView.setText("some_text");
   

3. Now, to set the background color, you need to define your own color in the res->values->colors.xml file as follows:

   <resources>
       <color name="my_color">#000000</color>
   </resources>
   

4. You can now use "my_color" color in your java file to set the background dynamically as follows:

   mTextView.setBackgroundResource(R.color.my_color);
   

In my case, I got the error on the setState line:

increment(){
  this.setState(state => {
    count: state.count + 1
  });
}

I changed it to this, now it works

increment(){
  this.setState(state => {
    const count = state.count + 1

    return {
      count
    };
  });
}

I have these mapped in my .gvimrc to let me hit command-[arrow] to move the height and width of my current window around:

" resize current buffer by +/- 5 
nnoremap <D-left> :vertical resize -5<cr>
nnoremap <D-down> :resize +5<cr>
nnoremap <D-up> :resize -5<cr>
nnoremap <D-right> :vertical resize +5<cr>

For MacVim, you have to put them in your .gvimrc (and not your .vimrc) as they'll otherwise get overwritten by the system .gvimrc

From application perspective, if one needs only to avoid duplicates then HashSet is what you are looking for since it's Lookup, Insert and Remove complexities are O(1) - constant. What this means it does not matter how many elements HashSet has it will take same amount of time to check if there's such element or not, plus since you are inserting elements at O(1) too it makes it perfect for this sort of thing.

void foo(void) is better because it explicitly says: no parameters allowed.

void foo() means you could (under some compilers) send parameters, at least if this is the declaration of your function rather than its definition.

Accessing the files directly on your phone is difficult, but you may be able to copy them to your computer where you can do anything you want with it. Without rooting you have 2 options:

1. If the application is debuggable you can use the run-as command in adb shell

   adb shell
   run-as com.your.packagename 
   cp /data/data/com.your.packagename/
   

2. Alternatively you can use Android's backup function.

   adb backup -noapk com.your.packagename
   

   You will now be prompted to 'unlock your device and confirm the backup operation'. It's best NOT to provide a password, otherwise it becomes more difficult to read the data. Just click on 'backup my data'. The resulting 'backup.ab' file on your computer contains all application data in android backup format. Basically it's a compressed tar file. This page explains how you can use OpenSSL's zlib command to uncompress it. You can use the adb restore backup.db command to restore the backup.

setTimeout(callback,t) is used to run callback after at least t millisecond. The actual delay depends on many external factors like OS timer granularity and system load.

So, there is a possibility that it will be called slightly after the set time, but will never be called before.

A timer can't span more than 24.8 days.

A more elegant way to convert json to csv is to use the map function without any framework:

var json = json3.items
var fields = Object.keys(json[0])
var replacer = function(key, value) { return value === null ? '' : value } 
var csv = json.map(function(row){
  return fields.map(function(fieldName){
    return JSON.stringify(row[fieldName], replacer)
  }).join(',')
})
csv.unshift(fields.join(',')) // add header column
 csv = csv.join('\r\n');
console.log(csv)

Output:

There is this MarkerClusterer client side utility available for google Map as specified here on Google Map developer Articles, here is brief on what's it's usage:

There are many approaches for doing what you asked for:

• Grid based clustering
• Distance based clustering
• Viewport Marker Management
• Fusion Tables
• Marker Clusterer
• MarkerManager

You can read about them on the provided link above.

Marker Clusterer uses Grid Based Clustering to cluster all the marker wishing the grid. Grid-based clustering works by dividing the map into squares of a certain size (the size changes at each zoom) and then grouping the markers into each grid square.

Before Clustering

After Clustering

I hope this is what you were looking for & this will solve your problem :)

If the sites are on separate domains, the calling page can't access the height of the iframe due to cross-browser domain restrictions. If you have access to both sites, you may be able to use the [document domain hack].1 Then anroesti's links should help.

The default return value of methods you haven't stubbed yet is false for boolean methods, an empty collection or map for methods returning collections or maps and null otherwise.

This also applies to method calls within when(...). In you're example when(myService.getListWithData(inputData).get()) will cause a NullPointerException because myService.getListWithData(inputData) is null - it has not been stubbed before.

One option is create mocks for all intermediate return values and stub them before use. For example:

ListWithData listWithData = mock(ListWithData.class);
when(listWithData.get()).thenReturn(item1);
when(myService.getListWithData()).thenReturn(listWithData);

Or alternatively, you can specify a different default answer when creating a mock, to make methods return a new mock instead of null: RETURNS_DEEP_STUBS

SomeService myService = mock(SomeService.class, Mockito.RETURNS_DEEP_STUBS);
when(myService.getListWithData().get()).thenReturn(item1);

You should read the Javadoc of Mockito.RETURNS_DEEP_STUBS which explains this in more detail and also has some warnings about its usage.

I hope this helps. Just note that your example code seems to have more issues, such as missing assert or verify statements and calling setters on mocks (which does not have any effect).

When the user starts making changes to the form, a boolean flag will be set. If the user then tries to navigate away from the page, you check that flag in the window.onunload event. If the flag is set, you show the message by returning it as a string. Returning the message as a string will popup a confirmation dialog containing your message.

If you are using ajax to commit the changes, you can set the flag to false after the changes have been committed (i.e. in the ajax success event).

In C, NAN is declared in <math.h>.

In C++, std::numeric_limits<double>::quiet_NaN() is declared in <limits>.

But for checking whether a value is NaN, you can't compare it with another NaN value. Instead use isnan() from <math.h> in C, or std::isnan() from <cmath> in C++.

my css

TR.gray-t {background:#949494;}
h3{
    padding-top:3px;
    font:bold 12px/2px Arial;
}

my html

<TR class='gray-t'>

I decrease the 2nd size in font.

padding-top is used to fix the size in IE7.

add to your .nav css block the

and it will work

In my case I need to do

sudo npm install  

my project is inside /var/www so I also need to set proper permissions.

$(this).parent().parent().attr('id');

Is how you would get the id of the parent's parent.

EDIT:

$(this).closest('ul').attr('id');

Is a more foolproof solution for your case.

yes, you're on the right track.

yes, square brackets are the usual indicator for optional items.

Typically, as you have sketched out, there is a commandline summary at the top, followed by details, ideally with samples for each option. (Your example shows lines in between each option description, but I assume that is an editing issue, and that your real program outputs indented option listings with no blank lines in between. This would be the standard to follow in any case.)

A newer trend, (maybe there is a POSIX specification that addresses this?), is the elimination of the man page system for documentation, and including all information that would be in a manpage as part of the program --help output. This extra will include longer descriptions, concepts explained, usage samples, known limitations and bugs, how to report a bug, and possibly a 'see also' section for related commands.

I hope this helps.

Thanks good work!

I switch between zsh and bash somewhat frequently. For a while, I used to have to source my bash_profile every switch. Then I found out you can (typically) do

exec bash --login

or just

exec bash -l

Shprink's code helped me the most, but to avoid the dropdown to go off-screen i updated it to:

JS:

$('ul.dropdown-menu [data-toggle=dropdown]').on('click', function(event) {
    // Avoid following the href location when clicking
    event.preventDefault(); 
    // Avoid having the menu to close when clicking
    event.stopPropagation(); 
    // If a menu is already open we close it
    $('ul.dropdown-menu [data-toggle=dropdown]').parent().removeClass('open');
    // opening the one you clicked on
    $(this).parent().addClass('open');

    var menu = $(this).parent().find("ul");
    var menupos = $(menu).offset();

    if (menupos.left + menu.width() > $(window).width()) {
        var newpos = -$(menu).width();
        menu.css({ left: newpos });    
    } else {
        var newpos = $(this).parent().width();
        menu.css({ left: newpos });
    }

});

CSS: FROM background-color: #eeeeee TO background-color: #c5c5c5 - white font & light background wasn't looking good.

.nav .open > a,
.nav .open > a:hover,
.nav .open > a:focus {
  background-color: #c5c5c5;
  border-color: #428bca;
}

I hope this helps people as much as it did for me!

But i hope Bootstrap add the subs feature back ASAP.

Try this:

RetVal = Shell("<full path to python.exe> " & "<full path to your python script>")

Or if the python script is in the same folder as the workbook, then you can try :

RetVal = Shell("<full path to python.exe> " & ActiveWorkBook.Path & "\<python script name>")

All details within <> are to be given. <> - indicates changeable fields

I guess this should work. But then again, if your script is going to call other files which are in different folders, it can cause errors unless your script has properly handled it. Hope it helps.

There is maybe a bit of a gotcha in the phrasing of the original question:

I need to check that two conditions are both true before enabling a button

The first thing to remember that the ng-disabled directive is evaluating a condition under which the button should be, well, disabled, but the original question is referring to the conditions under which it should en enabled. It will be enabled under any circumstances where the ng-disabled expression is not "truthy".

So, the first consideration is how to rephrase the logic of the question to be closer to the logical requirements of ng-disabled. The logical inverse of checking that two conditions are true in order to enable a button is that if either condition is false then the button should be disabled.

Thus, in the case of the original question, the pseudo-expression for ng-disabled is "disable the button if condition1 is false or condition2 is false". Translating into the Javascript-like code snippet required by Angular (https://docs.angularjs.org/guide/expression), we get:

!condition1 || !condition2

Zoomlar has it right!

The === options give me duplicated columns. So I use Seq instead.

val Lead_all = Leads.join(Utm_Master,
    Seq("Utm_Source","Utm_Medium","Utm_Campaign"),"left")

Of course, this only works when the names of the joining columns are the same.

Consider the following scenario:

public class Car {
  @Inject
  private Engine engine;  

  public Car() {
    engine.initialize();  
  }
  ...
}

Since Car has to be instantiated prior to field injection, the injection point engine is still null during the execution of the constructor, resulting in a NullPointerException.

This problem can be solved either by JSR-330 Dependency Injection for Java constructor injection or JSR 250 Common Annotations for the Java @PostConstruct method annotation.

@PostConstruct

JSR-250 defines a common set of annotations which has been included in Java SE 6.

The PostConstruct annotation is used on a method that needs to be executed after dependency injection is done to perform any initialization. This method MUST be invoked before the class is put into service. This annotation MUST be supported on all classes that support dependency injection.

JSR-250 Chap. 2.5 javax.annotation.PostConstruct

The @PostConstruct annotation allows for the definition of methods to be executed after the instance has been instantiated and all injects have been performed.

public class Car {
  @Inject
  private Engine engine;  

  @PostConstruct
  public void postConstruct() {
    engine.initialize();  
  }
  ...
} 

Instead of performing the initialization in the constructor, the code is moved to a method annotated with @PostConstruct.

The processing of post-construct methods is a simple matter of finding all methods annotated with @PostConstruct and invoking them in turn.

private  void processPostConstruct(Class type, T targetInstance) {
  Method[] declaredMethods = type.getDeclaredMethods();

  Arrays.stream(declaredMethods)
      .filter(method -> method.getAnnotation(PostConstruct.class) != null) 
      .forEach(postConstructMethod -> {
         try {
           postConstructMethod.setAccessible(true);
           postConstructMethod.invoke(targetInstance, new Object[]{});
        } catch (IllegalAccessException | IllegalArgumentException | InvocationTargetException ex) {      
          throw new RuntimeException(ex);
        }
      });
}

The processing of post-construct methods has to be performed after instantiation and injection have been completed.

git pull <gitreponame> <branchname>

Usually if you have only repo assigned to your code then the gitreponame would be origin.

If you are working on two repo's like one is local and another one for remote like you can check repo's list from git remote -v. this shows how many repo's are assigned to your current code.

BranchName should exists into corresponding gitreponame.

you can use following two commands to add or remove repo's

git remote add <gitreponame> <repourl>
git remote remove <gitreponame>

With VS 2015 and up, Use the Smart Command Line Arguments extension. This plug-in adds a window that allows you to turn arguments on and off:

The extension additionally stores the arguments in a JSON file, allowing you to commit them to source control. In addition to ensuring you don't have to type in all the arguments every single time, this serves as a useful supplement to your documentation for other developers to discover the available options.

Nothing, they are synonymous (Response.Write is simply a shorter way to express the act of writing to the response output).

If you are curious, the implementation of HttpResponse.Write looks like this:

public void Write(string s)
{
    this._writer.Write(s);
}

And the implementation of HttpResponse.Output is this:

public TextWriter Output
{
    get
    {
        return this._writer;
    }
}

So as you can see, Response.Write and Response.Output.Write are truly synonymous expressions.

If you want to preserve your commit (maybe you already spent some time writing a detailed commit message and don't want to lose it), and you only want to remove the file from the commit, but not from the repository entirely:

git checkout origin/<remote-branch> <filename>
git commit --amend

yes, we can declare an abstract class without any abstract method. the purpose of declaring a class as abstract is not to instantiate the class.

so two cases

1) abstract class with abstract methods.

these type of classes, we must inherit a class from this abstract class and must override the abstract methods in our class, ex: GenricServlet class

2) abstract class without abstract methods.

these type of classes, we must inherit a class from this abstract class, ex: HttpServlet class purpose of doing is although you if you don't implement your logic in child class you can get the parent logic

please check the HttpServlet source code

the issue is that a DataTemplate isn't part of an element its applied to it.

this means if you bind to the template you're binding to something that has no context.

however if you put a element inside the template then when that element is applied to the parent it gains a context and the binding then works

so this will not work

<DataTemplate >
    <DataTemplate.Resources>
        <CollectionViewSource x:Key="projects" Source="{Binding Projects}" >

but this works perfectly

<DataTemplate >
    <GroupBox Header="Projects">
        <GroupBox.Resources>
            <CollectionViewSource x:Key="projects" Source="{Binding Projects}" >

because after the datatemplate is applied the groupbox is placed in the parent and will have access to its Context

so all you have to do is remove the style from the template and move it into an element in the template

note that the context for a itemscontrol is the item not the control ie ComboBoxItem for ComboBox not the ComboBox itself in which case you should use the controls ItemContainerStyle instead

I did a benchmark test to try and answer this question, then found this post so here are my findings (which differ slightly from the other answers)

Here is the benchmark code:

require 'benchmark'

h = { abc: 'hello', 'another_key' => 123, 4567 => 'third' }
a = 1..10
many = 500_000

Benchmark.bm do |b|
  GC.start

  b.report("hash keys collect") do
    many.times do
      h.keys.collect(&:to_s)
    end
  end

  GC.start

  b.report("hash keys map") do
    many.times do
      h.keys.map(&:to_s)
    end
  end

  GC.start

  b.report("array collect") do
    many.times do
      a.collect(&:to_s)
    end
  end

  GC.start

  b.report("array map") do
    many.times do
      a.map(&:to_s)
    end
  end
end

And the results I got were:

                   user     system      total        real
hash keys collect  0.540000   0.000000   0.540000 (  0.570994)
hash keys map      0.500000   0.010000   0.510000 (  0.517126)
array collect      1.670000   0.020000   1.690000 (  1.731233)
array map          1.680000   0.020000   1.700000 (  1.744398) 

Perhaps an alias isn't free?

The label's information is stored in the ViewState input on postback (keep in mind the server knows nothing of the page outside of the form values posted back, which includes your label's text).. you would have to somehow update that on the client side to know what changed in that label, which I'm guessing would not be worth your time.

I'm not entirely sure what problem you're trying to solve here, but this might give you a few ideas of how to go about it:

You could create a hidden field to go along with your label, and anytime you update your label, you'd update that value as well.. then in the code behind set the Text property of the label to be what was in that hidden field.

SELECT COUNT(1) FROM FB 
WHERE Dte > DATE_SUB(now(), INTERVAL 2 MONTH)

I am assuming that you have requested for authorisation and registered your app for notification.

Here is the code to create local notifications

@available(iOS 10.0, *)
    func send_Noti()
    {
        //Create content for your notification 
        let content = UNMutableNotificationContent()
        content.title = "Test"
        content.body = "This is to test triggering of notification"

        //Use it to define trigger condition
        var date = DateComponents()
        date.calendar = Calendar.current
        date.weekday = 5 //5 means Friday
        date.hour = 14 //Hour of the day
        date.minute = 10 //Minute at which it should be sent


        let trigger = UNCalendarNotificationTrigger(dateMatching: date, repeats: true)
        let uuid = UUID().uuidString
        let req = UNNotificationRequest(identifier: uuid, content: content, trigger: trigger)

        let notificationCenter = UNUserNotificationCenter.current()
        notificationCenter.add(req) { (error) in
            print(error)
        }
    }

Standard Subversion layout

Create a git clone of that includes your Subversion trunk, tags, and branches with

git svn clone http://svn.example.com/project -T trunk -b branches -t tags

The --stdlayout option is a nice shortcut if your Subversion repository uses the typical structure:

git svn clone http://svn.example.com/project --stdlayout

Make your git repository ignore everything the subversion repo does:

git svn show-ignore >> .git/info/exclude

You should now be able to see all the Subversion branches on the git side:

git branch -r

Say the name of the branch in Subversion is waldo. On the git side, you'd run

git checkout -b waldo-svn remotes/waldo

The -svn suffix is to avoid warnings of the form

warning: refname 'waldo' is ambiguous.

To update the git branch waldo-svn, run

git checkout waldo-svn
git svn rebase

Starting from a trunk-only checkout

To add a Subversion branch to a trunk-only clone, modify your git repository's .git/config to contain

[svn-remote "svn-mybranch"]
        url = http://svn.example.com/project/branches/mybranch
        fetch = :refs/remotes/mybranch

You'll need to develop the habit of running

git svn fetch --fetch-all

to update all of what git svn thinks are separate remotes. At this point, you can create and track branches as above. For example, to create a git branch that corresponds to mybranch, run

git checkout -b mybranch-svn remotes/mybranch

For the branches from which you intend to git svn dcommit, keep their histories linear!

Solution is to wrap your padded div, with fixed width outer div

HTML

<div class="outer">
    <div class="inner">

        <!-- your content -->

    </div><!-- end .inner -->
</div><!-- end .outer -->

CSS

.outer, .inner {
    display: block;
}

.outer {
    /* specify fixed width */
    width: 300px;
    padding: 0;
}

.inner {
    /* specify padding, can be changed while remaining fixed width of .outer */
    padding: 5px;
}

You can also try using following fragments:

select  * from  Product_sales 
where  From_date  >= '2013-01-03' and game_date  <= '2013-01-09'

There is a documentation in SLf4J site to resolve this. I followed that and added slf4j-simple-1.6.1.jar to my aplication along with slf4j-api-1.6.1.jar which i already had.This solved my problem

slf4j

I got around this with len() and a simple if/else statement.

List elements will come back as an integer when wrapped in len() (1 for present, 0 for absent)

l = []

print(len(l)) # Prints 0

if len(l) == 0:
    print("Element is empty")
else:
    print("Element is NOT empty")

Output:

Element is empty    

I eventually figured it out. Place:

import warnings
warnings.filterwarnings('ignore')

inside ~/.ipython/profile_default/startup/disable-warnings.py. I'm leaving this question and answer for the record in case anyone else comes across the same issue.

Quite often it is useful to see a warning once. This can be set by:

warnings.filterwarnings(action='once')

Move excel variables which are global declare in your form to local like in my form I have:

Dim xls As New MyExcel.Interop.Application  
Dim xlb As MyExcel.Interop.Workbook

above two lines were declare global in my form so i moved these two lines to local function and now tool is working fine.

An update to @rleelr:
It's possible to view proxy settings in Google Chrome:

chrome://net-internals/#http2

Then select

View live HTTP/2 sessions

Then select one of the live sessions (you need to have some tabs open). There you find:

                  --> host = "play.google.com:443"

String rat_values = "Food 1 | Service 3 | Atmosphere 3 | Value for money 1 ";
    String[] value_split = rat_values.split("\\|");
    for (String string : value_split) {

    }

Remember that stringToEdit.replaceAll(String, String) returns the result string. It doesn't modify stringToEdit because Strings are immutable in Java. To get any change to stick, you should use

stringToEdit = stringToEdit.replaceAll("'", "\\'");

<strong> and <em> - unlike <b> and <i> - have clear purpose for web browsers for the blind.

A blind person doesn't browse the web visually, but by sound such as text readers. <strong> and <em>, in addition to encouraging something to be bold or italic, also convey loudness or stressing syllables respectively (OH MY! & Ooooooh Myyyyyyy!). Audio-only browsers are unpredictable when it comes to <b> and <i>... they may make them loud or stress them or they may not... you never can be sure unless you use <strong> and <em>.

Copy the files to the default directory for your other database files. To find out what that is, you can use the sp_helpfile procedure in SSMS. On my machine it is: C:\Program Files\Microsoft SQL Server\MSSQL10_50.SQLEXPRESS\MSSQL\DATA. By copying the files to this directory, they automatically get permissions applied that will allow the attach to succeed.

Here is a very good explanation :

How to open MDF files .

On OpenWRT the only way to reliably do this, at least for me, is by running these commands:

This will show either "link:down" or "link:up" on every port of your switch.

I've faced the exactly same problem but I've fixed it with another approache.

Using Ubuntu 18.04, first disable systemd-resolved service.

sudo systemctl disable systemd-resolved.service

Stop the service

sudo systemctl stop systemd-resolved.service

Then, remove the link to /run/systemd/resolve/stub-resolv.conf in /etc/resolv.conf

sudo rm /etc/resolv.conf

Add a manually created resolv.conf in /etc/

sudo vim /etc/resolv.conf

Add your prefered DNS server there

nameserver 208.67.222.222

I've tested this with success.

ssize_t is used for functions whose return value could either be a valid size, or a negative value to indicate an error. It is guaranteed to be able to store values at least in the range [-1, SSIZE_MAX] (SSIZE_MAX is system-dependent).

So you should use size_t whenever you mean to return a size in bytes, and ssize_t whenever you would return either a size in bytes or a (negative) error value.

See: http://pubs.opengroup.org/onlinepubs/007908775/xsh/systypes.h.html

Another Note: z-index must be considered when looking at children objects relative to other objects.

For example

<div class="container">
    <div class="branch_1">
        <div class="branch_1__child"></div>
    </div>
    <div class="branch_2">
        <div class="branch_2__child"></div>
    </div>
</div>

If you gave branch_1__child a z-index of 99 and you gave branch_2__child a z-index of 1, but you also gave your branch_2 a z-index of 10 and your branch_1 a z-index of 1, your branch_1__child still will not show up in front of your branch_2__child

Anyways, what I'm trying to say is; if a parent of an element you'd like to be placed in front has a lower z-index than its relative, that element will not be placed higher.

The z-index is relative to its containers. A z-index placed on a container farther up in the hierarchy basically starts a new "layer"

Incep[inception]tion

Here's a fiddle to play around:

https://jsfiddle.net/orkLx6o8/

cd /path/to/backupdir/
git clone /path/to/repo
cd /path/to/repo
git remote add backup /path/to/backupdir
git push --set-upstream backup master

this creates a backup and makes the setup, so that you can do a git push to update your backup, what is probably what you want to do. Just make sure, that /path/to/backupdir and /path/to/repo are at least different hard drives, otherwise it doesn't make that much sense to do that.

Use this for example:

cv2.namedWindow('finalImg', cv2.WINDOW_NORMAL)
cv2.imshow("finalImg",finalImg)

Building on Preet Sangha's solution, the following should safely cover the scenario where you're working with a large solution with the potential for several Inner Exceptions.

 try
 {
     object result = processClass.InvokeMethod("Create", methodArgs);
 }
 catch (Exception e)
 {
     // Here I was hoping to get an error code.
     if (ExceptionContainsErrorCode(e, 10004))
     {
         // Execute desired actions
     }
 }

...

private bool ExceptionContainsErrorCode(Exception e, int ErrorCode)
{
    Win32Exception winEx = e as Win32Exception;
    if (winEx != null && ErrorCode == winEx.ErrorCode) 
        return true;

    if (e.InnerException != null) 
        return ExceptionContainsErrorCode(e.InnerException, ErrorCode);

    return false;
}

This code has been unit tested.

I won't harp too much on the need for coming to appreciate and implement good practice when it comes to Exception Handling by managing each expected Exception Type within their own blocks.

If you want to learn about win32, WTL http://wtl.sourceforge.net/ is the pretty lightweight equivalent to MFC, but you have to love template to use it.

If you want something simple MFC is already integrated with VS, also it has a large base of extra code and workarounds of know bugs in the net already.

Also Qt is really great framework it have a nice set of tools, dialog editor, themes, and a lot of other stuff, plus your application will be ready to be cross platform, although it will require some time to get accustomed.

You also have Gtk, wxWindow, and you will have no problems if you have already used it on linux.

Do not create separate lists; create a list of lists:

results = []
with open('inputfile.txt') as inputfile:
    for line in inputfile:
        results.append(line.strip().split(','))

or better still, use the csv module:

import csv

results = []
with open('inputfile.txt', newline='') as inputfile:
    for row in csv.reader(inputfile):
        results.append(row)

Lists or dictionaries are far superiour structures to keep track of an arbitrary number of things read from a file.

Note that either loop also lets you address the rows of data individually without having to read all the contents of the file into memory either; instead of using results.append() just process that line right there.

Just for completeness sake, here's the one-liner compact version to read in a CSV file into a list in one go:

import csv

with open('inputfile.txt', newline='') as inputfile:
    results = list(csv.reader(inputfile))

Your compile SDK version must match the support library major version. This is the solution to your problem. You can check it easily in your Gradle Scripts in build.gradle file. Fx: if your compileSdkVersion is 23 your compile library must start at 23.

  compileSdkVersion 23
    buildToolsVersion "23.0.0"
    defaultConfig {
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 340
        versionName "3.4.0"
    }
dependencies {
    compile 'com.android.support:appcompat-v7:23.1.0'
    compile 'com.android.support:recyclerview-v7:23.0.1'
}

And always check that your Android Studoi has the supported API Level. You can check it in your Android SDK, like this:

ping is available on almost every OS. So you could make a system call and fetch the result.

df = df[[col for col in df.columns if not ('Unnamed' in col)]]

Finally I fixed the problem by modifying build.gradle like this:

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.2"

    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 26
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    implementation 'com.android.support:design:26.1.0'
}

I've removed these lines as these will produce more errors:

testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'

Also I had same problem with migrating an existing project from 2.3 to 3.0.1 and with modifying the project gradle files like this, I came up with a working solution:

build.gradle (module app)

android {
    compileSdkVersion 27
    buildToolsVersion "27.0.1"

    defaultConfig {
        applicationId "com.mobaleghan.tablighcalendar"
        minSdkVersion 16
        targetSdkVersion 27
    }

dependencies {
    implementation 'com.android.support:appcompat-v7:25.1.0'
    implementation 'com.android.support:design:25.1.0'
    implementation 'com.android.support:preference-v7:25.1.0'
    implementation 'com.android.support:recyclerview-v7:25.1.0'
    implementation 'com.android.support:support-annotations:25.1.0'
    implementation 'com.android.support:support-v4:25.1.0'
    implementation 'com.android.support:cardview-v7:25.1.0'
    implementation 'com.google.android.apps.dashclock:dashclock-api:2.0.0'
}

Top level build.gradle

buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

There are 4 versions of the CRT link libraries present in vc\lib:

• libcmt.lib: static CRT link library for a release build (/MT)
• libcmtd.lib: static CRT link library for a debug build (/MTd)
• msvcrt.lib: import library for the release DLL version of the CRT (/MD)
• msvcrtd.lib: import library for the debug DLL version of the CRT (/MDd)

Look at the linker options, Project + Properties, Linker, Command Line. Note how these libraries are not mentioned here. The linker automatically figures out what /M switch was used by the compiler and which .lib should be linked through a #pragma comment directive. Kinda important, you'd get horrible link errors and hard to diagnose runtime errors if there was a mismatch between the /M option and the .lib you link with.

You'll see the error message you quoted when the linker is told both to link to msvcrt.lib and libcmt.lib. Which will happen if you link code that was compiled with /MT with code that was linked with /MD. There can be only one version of the CRT.

/NODEFAULTLIB tells the linker to ignore the #pragma comment directive that was generated from the /MT compiled code. This might work, although a slew of other linker errors is not uncommon. Things like errno, which is a extern int in the static CRT version but macro-ed to a function in the DLL version. Many others like that.

Well, fix this problem the Right Way, find the .obj or .lib file that you are linking that was compiled with the wrong /M option. If you have no clue then you could find it by grepping the .obj/.lib files for "/MT"

Btw: the Windows executables (like version.dll) have their own CRT version to get their job done. It is located in c:\windows\system32, you cannot reliably use it for your own programs, its CRT headers are not available anywhere. The CRT DLL used by your program has a different name (like msvcrt90.dll).

For some reason the round() method doesn't work if you have float numbers with many decimal places, but this will.

decimals = 2    
df['column'] = df['column'].apply(lambda x: round(x, decimals))

Pre C++11:

The function will not return the local variable, but rather a copy of it. Your compiler might however perform an optimization where no actual copy action is made.

See this question & answer for further details.

C++11:

The function will move the value. See this answer for further details.

For me, this works:

function transferAllStyles(elemFrom, elemTo)
{
  var prop;
  for (prop in elemFrom.style)
    if (typeof prop == "string")
      try { elemTo.style[prop] = elemFrom.style[prop]; }
      catch (ex) { /* don't care */ }
}

If you have a Decimal or similar numeric type, you can use:

Math.Round(myNumber, 2)

EDIT: So, in your case, it would be:

Public Class Form1
  Private Sub btncalc_Click(ByVal sender As System.Object,
                            ByVal e As System.EventArgs) Handles btncalc.Click
    txtA.Text = Math.Round((Val(txtD.Text) / Val(txtC.Text) * Val(txtF.Text) / Val(txtE.Text)), 2)
    txtB.Text = Math.Round((Val(txtA.Text) * 1000 / Val(txtG.Text)), 2)
  End Sub
End Class

You have to set both layout_gravity and layout_columntWeight on your columns

<android.support.v7.widget.GridLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <TextView android:text="??? ???"
        app:layout_gravity="fill_horizontal"
        app:layout_columnWeight="1"
        />

    <TextView android:text="??? ???"
        app:layout_gravity="fill_horizontal"
        app:layout_columnWeight="1"
        />

    <TextView android:text="??? ???"
        app:layout_gravity="fill_horizontal"
        app:layout_columnWeight="1"
        />
 </android.support.v7.widget.GridLayout>

One option is to put the subquery in a LEFT JOIN:

select sum ( t.graduates ) - t1.summedGraduates 
from table as t
    left join 
     ( 
        select sum ( graduates ) summedGraduates, id
        from table  
        where group_code not in ('total', 'others' )
        group by id 
    ) t1 on t.id = t1.id
where t.group_code = 'total'
group by t1.summedGraduates 

Perhaps a better option would be to use SUM with CASE:

select sum(case when group_code = 'total' then graduates end) -
    sum(case when group_code not in ('total','others') then graduates end)
from yourtable

One of my websites involves a div whose size is variable and you won't know it ahead of time. it is an outer div with 2 nested divs, the outer div is the same width as the first nested div, which is the content, and the second nested div right below the content is the caption, which must be centered. Because the width is not known, I use jQuery to adjust accordingly.

so my html is this

<div id='outer-container'>
<div id='inner-container'></div>
<div id='captions'></div>
</div>

and then I center the captions in jQuery like this

captionWidth=$("#captions").css("width");
outerWidth=$("#outer-container").css("width");
marginIndent=(outerWidth-captionWidth)/2;
$("#captions").css("margin","0px "+marginIndent+"px");

I had same error, I think the problem is that the error text is confusing, because its giving a false key name.

In your case It should say "There is no ViewData item of type 'IEnumerable' that has the key "Submarkets"".

My error was a misspelling in the view code (your "Submarkets"), but the error text made me go crazy.

I post this answer because I want to say people looking for this error, like I was, that the problem is that its not finding the IENumerable, but in the var that its supposed to look for it ("Submarkets" in this case), not in the one showed in error ("submarket_0").

Accepted answer is very interesting, but as you said the convention is applied if you dont specify the 2nd parameter, in this case it was specified, but the var was not found (in your case because the viewdata had not it, in my case because I misspelled the var name)

Hope this helps!

try like this (no pun intended btw)

script {
  try {
      sh 'do your stuff'
  } catch (Exception e) {
      echo 'Exception occurred: ' + e.toString()
      sh 'Handle the exception!'
  }
}

The key is to put try...catch in a script block in declarative pipeline syntax. Then it will work. This might be useful if you want to say continue pipeline execution despite failure (eg: test failed, still you need reports..)

If you want to do the same thing in C# based on Ciarán Answer

string sSheetName = null;
string sConnection = null;
DataTable dtTablesList = default(DataTable);
OleDbCommand oleExcelCommand = default(OleDbCommand);
OleDbDataReader oleExcelReader = default(OleDbDataReader);
OleDbConnection oleExcelConnection = default(OleDbConnection);

sConnection = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\\Test.xls;Extended Properties=\"Excel 12.0;HDR=No;IMEX=1\"";

oleExcelConnection = new OleDbConnection(sConnection);
oleExcelConnection.Open();

dtTablesList = oleExcelConnection.GetSchema("Tables");

if (dtTablesList.Rows.Count > 0) 
{
    sSheetName = dtTablesList.Rows[0]["TABLE_NAME"].ToString();
}

dtTablesList.Clear();
dtTablesList.Dispose();


if (!string.IsNullOrEmpty(sSheetName)) {
    oleExcelCommand = oleExcelConnection.CreateCommand();
    oleExcelCommand.CommandText = "Select * From [" + sSheetName + "]";
    oleExcelCommand.CommandType = CommandType.Text;
    oleExcelReader = oleExcelCommand.ExecuteReader();
    nOutputRow = 0;

    while (oleExcelReader.Read())
    {
    }
    oleExcelReader.Close();
}
oleExcelConnection.Close();

here is another way read Excel into a DataTable without using OLEDB very quick Keep in mind that the file ext would have to be .CSV for this to work properly

private static DataTable GetDataTabletFromCSVFile(string csv_file_path)
{
    csvData = new DataTable(defaultTableName);
    try
    {
        using (TextFieldParser csvReader = new TextFieldParser(csv_file_path))
        {
            csvReader.SetDelimiters(new string[]
            {
                tableDelim 
            });
            csvReader.HasFieldsEnclosedInQuotes = true;
            string[] colFields = csvReader.ReadFields();
            foreach (string column in colFields)
            {
                DataColumn datecolumn = new DataColumn(column);
                datecolumn.AllowDBNull = true;
                csvData.Columns.Add(datecolumn);
            }

            while (!csvReader.EndOfData)
            {
                string[] fieldData = csvReader.ReadFields();
                //Making empty value as null
                for (int i = 0; i < fieldData.Length; i++)
                {
                    if (fieldData[i] == string.Empty)
                    {
                        fieldData[i] = string.Empty; //fieldData[i] = null
                    }
                    //Skip rows that have any csv header information or blank rows in them
                    if (fieldData[0].Contains("Disclaimer") || string.IsNullOrEmpty(fieldData[0]))
                    {
                        continue;
                    }
                }
                csvData.Rows.Add(fieldData);
            }
        }
    }
    catch (Exception ex)
    {
    }
    return csvData;
}

I like the simplicity of tabulary package:

\usepackage{tabulary}
...
\begin{tabulary}{\linewidth}{LCL}
    \hline
    Short sentences      & \#  & Long sentences                                                 \\
    \hline
    This is short.       & 173 & This is much loooooooonger, because there are many more words.  \\
    This is not shorter. & 317 & This is still loooooooonger, because there are many more words. \\
    \hline
\end{tabulary} 

In the example, you arrange the whole width of the table with respect to \textwidth. E.g 0.4 of it. Then the rest is automatically done by the package.

Most of the example is taken from http://en.wikibooks.org/wiki/LaTeX/Tables .

Make sure that...

• There's an = sign before the formula
• There's no white space before the = sign
• There are no quotes around the formula (must be =A1, instead of "=A1")
• You're not in formula view (hit Ctrl + ` to switch between modes)
• The cell format is set to General instead of Text
• If simply changing the format doesn't work, hit F2, Enter
• Undoing actions (CTRL+Z) back until the value shows again and then simply redoing all those actions with CTRL-Y also worked for some users

You can not alter constraints ever but you can drop them and then recreate.

Have look on this

ALTER TABLE your_table DROP CONSTRAINT ACTIVEPROG_FKEY1;

and then recreate it with ON DELETE CASCADE like this

ALTER TABLE your_table
add CONSTRAINT ACTIVEPROG_FKEY1 FOREIGN KEY(ActiveProgCode) REFERENCES PROGRAM(ActiveProgCode)
    ON DELETE CASCADE;

hope this help

varchar(max) for SQLServer2005

varchar(65535) for MySQL 5.0.3 and later

This will allocate storage as need and shouldn't affect performance.

Well, initially, we should know what caused the error to happen, then the solution will be easy. The reason have already been pointed out by the accepted answer, but it is somehow incomplete (also the solution).

The problem is, one or more files had conflict(s) previously, but Git sees them as unresolved. Yes, you might already edited those files and resolved the conflicts, but Git does not know about that. You should tell Git "Hey, there are no more conflicts from the previous merge!". Note that, the merge is not necessarily caused by a git merge, but also by a git stash pop, for example.

Remember, git status can tell you what Git knows now. If there are some unresolved merge conflicts to Git, then it is shown in a separated Unmerged paths section, with the files marked as both modified (always?). If you have noticed, this section is between two staged and unstaged sections. From this, I personally understand that, "Unmerged paths are those you should either move into staged or unstaged areas, as Git can work only with these two areas".

So, to tell Git the conflicts have been resolved, you should either move these changes to staged or unstaged areas. In recent versions of Git, when you do a git status, it tells you how (woah! You should ask yourself how you haven't seen this yet?):

$ git status
...
Unmerged paths:
  (use "git restore --staged <file>..." to unstage)
  (use "git add <file>..." to mark resolution)
        both modified:   path/to/file.txt
...

So, to stage it (and maybe commit it):

$ git add path/to/file.txt

And to make it unstaged (e.g. you don't want to commit it now):

$ git restore --staged path/to/file.txt

Note: Forgetting to write --staged option possibly could spawn a super-hungry dragon to eat your past two days, in the case of not using a good text-editor or IDE.

Note: While git restore command is experimental yet, it should be stable enough to be used (thanks to a comment by @VonC, refer to it for more details on that).

You can use MySQL's DATE() function:

WHERE DATE(datetime) = '2009-10-20'

You could also try this:

WHERE datetime LIKE '2009-10-20%'

See this answer for info on the performance implications of using LIKE.

In the hypothetical situation where you could perform a potentially expensive non-const operation on an object, returning by const-value prevents you from accidentally calling this operation on a temporary. Imagine that + returned a non-const value, and you could write:

(a + b).expensive();

In the age of C++11, however, it is strongly advised to return values as non-const so that you can take full advantage of rvalue references, which only make sense on non-constant rvalues.

In summary, there is a rationale for this practice, but it is essentially obsolete.

In Ruby and Bash, you can use $ inside parentheses.

/(\S+?)/(\d{4}-\d{2}-\d{2})-(\d+)(/|$)

(This solution is similar to Pete Boughton's, but preserves the usage of $, which means end of line, rather than using \z, which means end of string.)

pymssql is a DB-API Python module, based on FreeTDS. It worked for me. Create some helper functions, if you need, and use it from Python shell.

The usual way is to use zip():

for x, y in zip(a, b):
    # x is from a, y is from b

This will stop when the shorter of the two iterables a and b is exhausted. Also worth noting: itertools.izip() (Python 2 only) and itertools.izip_longest() (itertools.zip_longest() in Python 3).

As Google tells, for now, don't forget to add also readable on external storage in the manifest :

Given the following tables..

Domain Table
dom_id | dom_url

Review Table
rev_id | rev_dom_from | rev_dom_for

Try this sql... (It's pretty much the same thing that Stephen Wrighton wrote above) The trick is that you are basically selecting from the domain table twice in the same query and joining the results.

Select d1.dom_url, d2.dom_id from
review r, domain d1, domain d2
where d1.dom_id = r.rev_dom_from
and d2.dom_id = r.rev_dom_for

If you are still stuck, please be more specific with exactly it is that you don't understand.

Another solution to avoid inserting html into data-title is to create independant div with tooltip html content, and refer to this div when creating your tooltip :

<!-- Tooltip link -->
<p><span class="tip" data-tip="my-tip">Hello world</span></p>

<!-- Tooltip content -->
<div id="my-tip" class="tip-content hidden">
    <h2>Tip title</h2>
    <p>This is my tip content</p>
</div>

<script type="text/javascript">
    $(document).ready(function () {
        // Tooltips
        $('.tip').each(function () {
            $(this).tooltip(
            {
                html: true,
                title: $('#' + $(this).data('tip')).html()
            });
        });
    });
</script>

This way you can create complex readable html content, and activate as many tooltips as you want.

Since Symfony 3.3 you can use binding, like

services:
_defaults:
    autowire: true      
    autoconfigure: true
    bind:
        $kernelProjectDir: '%kernel.project_dir%'

After that you can use parameter $kernelProjectDir in any controller OR service. Just like

class SomeControllerOrService
{
    public function someAction(...., $kernelProjectDir)
    {
          .....

Global.asax is the asp.net application file.

It is an optional file that handles events raised by ASP.NET or by HttpModules. Mostly used for application and session start/end events and for global error handling.

When used, it should be in the root of the website.

You should be able to use the /quiet or /qn options with msiexec to perform a silent install.

MSI packages export public properties, which you can set with the PROPERTY=value syntax on the end of the msiexec parameters.

For example, this command installs a package with no UI and no reboot, with a log and two properties:

msiexec /i c:\path\to\package.msi /quiet /qn /norestart /log c:\path\to\install.log PROPERTY1=value1 PROPERTY2=value2

You can read the options for msiexec by just running it with no options from Start -> Run.

If this is nullable int field then yes.

update TableName
set FiledName = null
where Id = SomeId

You just do CSS changes for parent div

.parent-div { 
        text-align: center;
        display: block;
}

use num_rows to get correct count for queries with conditions

$result = $connect->query("select * from table where id='$iid'");
$count=$result->num_rows;
echo "$count";

To exit your application you can call

System.Windows.Application.Current.Shutdown();

As described in the documentation to the Application.Shutdown method you can also modify the shutdown behavior of your application by specifying a ShutdownMode:

Shutdown is implicitly called by Windows Presentation Foundation (WPF) in the following situations:

• When ShutdownMode is set to OnLastWindowClose.
• When the ShutdownMode is set to OnMainWindowClose.
• When a user ends a session and the SessionEnding event is either unhandled, or handled without cancellation.

Please also note that Application.Current.Shutdown(); may only be called from the thread that created the Application object, i.e. normally the main thread.

You can use requests-html which will download and use chromium underneath.

from requests_html import HTML

html = HTML(html="<a href='http://www.example.com/'>")

script = """
function escramble_758(){
    var a,b,c
    a='+1 '
    b='84-'
    a+='425-'
    b+='7450'
    c='9'
    return a+c+b;
}
"""

val = html.render(script=script, reload=False)
print(val)
# +1 425-984-7450

function chgAction( action_name )
{
    if( action_name=="aaa" ) {
        document.search-theme-form.action = "/AAA";
    }
    else if( action_name=="bbb" ) {
        document.search-theme-form.action = "/BBB";
    }
    else if( action_name=="ccc" ) {
        document.search-theme-form.action = "/CCC";
    }
}

And your form needs to have name in this case:

<form action="/"  accept-charset="UTF-8" method="post" name="search-theme-form" id="search-theme-form">

java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to id.co.bni.switcherservice.model.SwitcherServiceSource

Problem is

(List<SwitcherServiceSource>) LoadSource.list();

This will return a List of Object arrays (Object[]) with scalar values for each column in the SwitcherServiceSource table. Hibernate will use ResultSetMetadata to deduce the actual order and types of the returned scalar values.

Solution

List<Object> result = (List<Object>) LoadSource.list(); 
Iterator itr = result.iterator();
while(itr.hasNext()){
   Object[] obj = (Object[]) itr.next();
   //now you have one array of Object for each row
   String client = String.valueOf(obj[0]); // don't know the type of column CLIENT assuming String 
   Integer service = Integer.parseInt(String.valueOf(obj[1])); //SERVICE assumed as int
   //same way for all obj[2], obj[3], obj[4]
}

Reading this original article on The Code Project will help you a lot: Visual Representation of SQL Joins.

Also check this post: SQL SERVER – Better Performance – LEFT JOIN or NOT IN?.

Find original one at: Difference between JOIN and OUTER JOIN in MySQL.

Check permission issues, mysql config.

Also check if you haven't reached disk space, quota limits.

Note: Some systems are limiting number of files (not just space), deleting some old session files helped fixed the issue in my case.

    <?php
if (isset($_POST['birthdate'])) {
    $timestamp = strtotime($_POST['birthdate']); 
    $date=date('d',$timestamp);
    $month=date('m',$timestamp);
    $year=date('Y',$timestamp);
}
?>  

This one did it for me:

var input = $("<input>")
               .attr("type", "hidden")
               .attr("name", "mydata").val("bla");
$('#form1').append(input);

is based on the Daff's answer, but added the NAME attribute to let it show in the form collection and changed VALUE to VAL Also checked the ID of the FORM (form1 in my case)

used the Firefox firebug to check whether the element was inserted.

Hidden elements do get posted back in the form collection, only read-only fields are discarded.

Epsilon is your "fuzz factor," since doubles may not be exactly equal. Epsilon lets you describe how close they have to be.

If you were expecting 3.14159 but would take anywhere from 3.14059 to 3.14259 (that is, within 0.001), then you should write something like

double myPi = 22.0d / 7.0d; //Don't use this in real life!
assertEquals(3.14159, myPi, 0.001);

(By the way, 22/7 comes out to 3.1428+, and would fail the assertion. This is a good thing.)

As a contemporary alternative, there is a standard now for client side cryptography. This has the advantage of being optimised by the browser itself.

Taken from the example in the documentation:

async function sha256(message) {

    // encode as UTF-8
    const msgBuffer = new TextEncoder('utf-8').encode(message);

    // hash the message
    const hashBuffer = await crypto.subtle.digest('SHA-256', msgBuffer);

    // convert ArrayBuffer to Array
    const hashArray = Array.from(new Uint8Array(hashBuffer));

    // convert bytes to hex string
    const hashHex = hashArray.map(b => ('00' + b.toString(16)).slice(-2)).join('');
    return hashHex;
}

sha256('abc').then(hash => console.log(hash));

(async function() {
    const hash = await sha256('abc');
}());

MD5 is likely unsupported, however the likes of SHA-256, SHA-384, and SHA-512 are.

And those will likely be able to be calculated server side also.

Here's some documentation on usage: https://developer.mozilla.org/en-US/docs/Web/API/SubtleCrypto/digest

And cross browser compatibility: https://caniuse.com/#feat=cryptography

Yet another solution:

I was stumped because I was including boost_regex-vc120-mt-gd-1_58.lib in my Link->Additional Dependencies property, but the link kept telling me it couldn't open libboost_regex-vc120-mt-gd-1_58.lib (note the lib prefix). I didn't specify libboost_regex-vc120-mt-gd-1_58.lib.

I was trying to use (and had built) the boost dynamic libraries (.dlls) but did not have the BOOST_ALL_DYN_LINK macro defined. Apparently there are hints in the compile to include a library, and without BOOST_ALL_DYN_LINK it looks for the static library (with the lib prefix), not the dynamic library (without a lib prefix).

You can also consider contract classes implemented with the NVI (Non Virtual Interface Pattern). For instance:

struct Contract1 : boost::noncopyable
{
    virtual ~Contract1();
    void f(Parameters p) {
        assert(checkFPreconditions(p)&&"Contract1::f, pre-condition failure");
        // + class invariants.
        do_f(p);
        // Check post-conditions + class invariants.
    }
private:
    virtual void do_f(Parameters p) = 0;
};
...
class Concrete : public Contract1, public Contract2
{
private:
    virtual void do_f(Parameters p); // From contract 1.
    virtual void do_g(Parameters p); // From contract 2.
};

Just setting the return value to the function name is still not exactly the same as the Java (or other) return statement, because in java, return exits the function, like this:

public int test(int x) {
    if (x == 1) {
        return 1; // exits immediately
    }

    // still here? return 0 as default.
    return 0;
}

In VB, the exact equivalent takes two lines if you are not setting the return value at the end of your function. So, in VB the exact corollary would look like this:

Public Function test(ByVal x As Integer) As Integer
    If x = 1 Then
        test = 1 ' does not exit immediately. You must manually terminate...
        Exit Function ' to exit
    End If

    ' Still here? return 0 as default.
    test = 0
    ' no need for an Exit Function because we're about to exit anyway.
End Function 

Since this is the case, it's also nice to know that you can use the return variable like any other variable in the method. Like this:

Public Function test(ByVal x As Integer) As Integer

    test = x ' <-- set the return value

    If test <> 1 Then ' Test the currently set return value
        test = 0 ' Reset the return value to a *new* value
    End If

End Function 

Or, the extreme example of how the return variable works (but not necessarily a good example of how you should actually code)—the one that will keep you up at night:

Public Function test(ByVal x As Integer) As Integer

    test = x ' <-- set the return value

    If test > 0 Then

        ' RECURSIVE CALL...WITH THE RETURN VALUE AS AN ARGUMENT,
        ' AND THE RESULT RESETTING THE RETURN VALUE.
        test = test(test - 1)

    End If

End Function

Don't forget to keep the input field on focus for future typing with input.focus(); inside the function.

I had this problem before and I made fallback way for loading. Basically first way work within .jar file and second way works within eclipse or other IDE.

public class MyClass {

    public static InputStream accessFile() {
        String resource = "my-file-located-in-resources.txt";

        // this is the path within the jar file
        InputStream input = MyClass.class.getResourceAsStream("/resources/" + resource);
        if (input == null) {
            // this is how we load file within editor (eg eclipse)
            input = MyClass.class.getClassLoader().getResourceAsStream(resource);
        }

        return input;
    }
}

The Revert command in the context menu ignores your edits and returns the working copy to its previous state. You may also select the desired revision other than the "Head" when you "CheckOut" from the repository.

string[] lines = File.ReadLines("c:\\file.txt").ToArray();

Although one wonders why you'll want to do that when ReadAllLines works just fine.

Or perhaps you just want to enumerate with the return value of File.ReadLines:

var lines = File.ReadAllLines("c:\\file.txt");
foreach (var line in lines)
{
    Console.WriteLine("\t" + line);
}

You can also use defaultdict to address this situation. It goes something like this:

from collections import defaultdict

#initialises the dictionary with values as list
aTargetDictionary = defaultdict(list)

for aKey in aSourceDictionary:
    aTargetDictionary[aKey].append(aSourceDictionary[aKey])

Well pandas use bitwise & | and each condition should be wrapped in a ()

For example following works

data_query = data[(data['year'] >= 2005) & (data['year'] <= 2010)]

But the same query without proper brackets does not

data_query = data[(data['year'] >= 2005 & data['year'] <= 2010)]

It is a hard question in the C/C++ world, with so many elements beyond the standard.

I think header file order is not a serious problem as long as it compiles, like squelart said.

My ideas is: If there is no conflict of symbols in all those headers, any order is OK, and the header dependency issue can be fixed later by adding #include lines to the flawed .h.

The real hassle arises when some header changes its action (by checking #if conditions) according to what headers are above.

For example, in stddef.h in VS2005, there is:

#ifdef  _WIN64
#define offsetof(s,m)   (size_t)( (ptrdiff_t)&(((s *)0)->m) )
#else
#define offsetof(s,m)   (size_t)&(((s *)0)->m)
#endif

Now the problem: If I have a custom header ("custom.h") that needs to be used with many compilers, including some older ones that don't provide offsetof in their system headers, I should write in my header:

#ifndef offsetof
#define offsetof(s,m)   (size_t)&(((s *)0)->m)
#endif

And be sure to tell the user to #include "custom.h" after all system headers, otherwise, the line of offsetof in stddef.h will assert a macro redefinition error.

We pray not to meet any more of such cases in our career.

Either make a Comparator that can compare your objects, or if they are all instances of the same class, you can make that class implement Comparable. You can then use Collections.sort() to do the actual sorting.

Here's the map solution:

#include <iostream>
#include <map>

typedef std::map<char, char> BasePairMap;

int main()
{
    BasePairMap m;
    m['A'] = 'T';
    m['T'] = 'A';
    m['C'] = 'G';
    m['G'] = 'C';

    std::cout << "A:" << m['A'] << std::endl;
    std::cout << "T:" << m['T'] << std::endl;
    std::cout << "C:" << m['C'] << std::endl;
    std::cout << "G:" << m['G'] << std::endl;

    return 0;
}

I'd recommend you go with REST first - if you're using Java look at JAX-RS and the Jersey implementation. REST is much simpler and easy to interop in many languages.

As others have said in this thread, the problem with SOAP is its complexity when the other WS-* specifications come in and there are countless interop issues if you stray into the wrong parts of WSDL, XSDs, SOAP, WS-Addressing etc.

The best way to judge the REST v SOAP debate is look on the internet - pretty much all the big players in the web space, google, amazon, ebay, twitter et al - tend to use and prefer RESTful APIs over the SOAP ones.

The other nice approach to going with REST is that you can reuse lots of code and infratructure between a web application and a REST front end. e.g. rendering HTML versus XML versus JSON of your resources is normally pretty easy with frameworks like JAX-RS and implicit views - plus its easy to work with RESTful resources using a web browser

If you remove the href attribute the anchor will be not focusable and it will look like simple text, but it will still be clickable.

You can use this simple code:

One-liner in Kotlin:

window.statusBarColor = ContextCompat.getColor(this, R.color.colorName)

Original answer with Java & manual version check:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    getWindow().setStatusBarColor(getResources().getColor(R.color.colorAccentDark_light, this.getTheme()));
} else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    getWindow().setStatusBarColor(getResources().getColor(R.color.colorAccentDark_light));
}
