I have tried to recreate the simple pagination example given by piotr-berebecki which was great. But when there will be a lot of pages then the pagination will overflow in the screen. So, I used previous and back button along with forward and backward button to stream back and forth between the pages. And for design part I have used bootstrap 3.

You can customize no of pages to display in pagination using the pagebound values. Make sure to use same value for upperPageBound and pageBound.

You need to do a couple of things to use the library:

1. Make sure that you have both the *.lib and the *.dll from the library you want to use. If you don't have the *.lib, skip #2

2. Put a reference to the *.lib in the project. Right click the project name in the Solution Explorer and then select Configuration Properties->Linker->Input and put the name of the lib in the Additional Dependencies property.

3. You have to make sure that VS can find the lib you just added so you have to go to the Tools menu and select Options... Then under Projects and Solutions select VC++ Directories,edit Library Directory option. From within here you can set the directory that contains your new lib by selecting the 'Library Files' in the 'Show Directories For:' drop down box. Just add the path to your lib file in the list of directories. If you dont have a lib you can omit this, but while your here you will also need to set the directory which contains your header files as well under the 'Include Files'. Do it the same way you added the lib.

After doing this you should be good to go and can use your library. If you dont have a lib file you can still use the dll by importing it yourself. During your applications startup you can explicitly load the dll by calling LoadLibrary (see: http://msdn.microsoft.com/en-us/library/ms684175(VS.85).aspx for more info)

Cheers!

EDIT

Remember to use #include < Foo.h > as opposed to #include "foo.h". The former searches the include path. The latter uses the local project files.

you can as well try:

scanner := bufio.NewScanner(os.Stdin)
for scanner.Scan() {
    fmt.Println(scanner.Text())
}

if scanner.Err() != nil {
    // handle error.
}

I'm using Database First and when this error happened to me my solution was to force ProviderManifestToken="2005" in edmx file (making the models compatible with SQL Server 2005). Don't know if something similar is possible for Code First.

The issue caused by the docker container which exits as soon as the "start" process finishes. i added a command that runs forever and it worked. This issue mentioned here

The second clause does not need a !variable.nil? check—if evaluation reaches that point, variable.nil is guaranteed to be false (because of short-circuiting).

This should be sufficient:

variable = id if variable.nil? || variable.empty?

If you're working with Ruby on Rails, Object.blank? solves this exact problem:

An object is blank if it’s false, empty, or a whitespace string. For example, "", " ", nil, [], and {} are all blank.

I use logback.groovy to configure my logback but you can do it with xml config as well:

import static ch.qos.logback.classic.Level.*
import static ch.qos.logback.core.spi.FilterReply.DENY
import static ch.qos.logback.core.spi.FilterReply.NEUTRAL
import ch.qos.logback.classic.boolex.GEventEvaluator
import ch.qos.logback.classic.encoder.PatternLayoutEncoder
import ch.qos.logback.core.ConsoleAppender
import ch.qos.logback.core.filter.EvaluatorFilter

def patternExpression = "%date{ISO8601} [%5level] %msg%n"

appender("STDERR", ConsoleAppender) {
    filter(EvaluatorFilter) {
      evaluator(GEventEvaluator) {
        expression = 'e.level.toInt() >= WARN.toInt()'
      }
      onMatch = NEUTRAL
      onMismatch = DENY
    }
    encoder(PatternLayoutEncoder) {
      pattern = patternExpression
    }
    target = "System.err"
  }

appender("STDOUT", ConsoleAppender) {
    filter(EvaluatorFilter) {
      evaluator(GEventEvaluator) {
        expression = 'e.level.toInt() < WARN.toInt()'
      }
      onMismatch = DENY
      onMatch = NEUTRAL
    }
    encoder(PatternLayoutEncoder) {
      pattern = patternExpression
    }
    target = "System.out"
}

logger("org.hibernate.type", WARN)
logger("org.hibernate", WARN)
logger("org.springframework", WARN)

root(INFO,["STDERR","STDOUT"])

I think to use GEventEvaluator is simplier because there is no need to create filter classes.
I apologize for my English!

In MVVM (wich makes a lot of things a lot easier - you should try it) you would have two properties in your ViewModel Text that is bound to your TextBox and you would have an ICommand property Apply (or similar) that is bound to the button:

<Button Command="Apply">Apply</Button>

The ICommand interface has a Method CanExecute that is where you return true if (!string.IsNullOrWhiteSpace(this.Text). The rest is done by WPF for you (enabling/disabling, executing the actual command on click).

The linked article explains it in detail.

If you want to add this behaviour to a shorthand animation property definition, the order of sub-properties is as follows

animation-name - default none

animation-duration - default 0s

animation-timing-function - default ease

animation-delay - default 0s

animation-iteration-count - default 1

animation-direction - default normal

animation-fill-mode - you need to set this to forwards

animation-play-state - default running

Therefore in the most common case, the result will be something like this

animation: colorchange 1s ease 0s 1 normal forwards;

My solution to not having sessionStorage transferable over tabs was to create a localProfile and bang off this variable. If this variable is set but my sessionStorage variables arent go ahead and reinitialize them. When user logs out window closes destroy this localStorage variable

A cleaner alternative of putting your config file into a subfolder of src/main/resources would be to enhance your classpath locations. This is extremely easy to do with Maven.

For instance, place your property file in a new folder src/main/config, and add the following to your pom:

 <build>
    <resources>
        <resource>
            <directory>src/main/config</directory>
        </resource>
    </resources>
 </build>

From now, every files files under src/main/config is considered as part of your classpath (note that you can exclude some of them from the final jar if needed: just add in the build section:

    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-jar-plugin</artifactId>
            <configuration>
                <excludes>
                    <exclude>my-config.properties</exclude>
                </excludes>
            </configuration>
        </plugin>
    </plugins>

so that my-config.properties can be found in your classpath when you run your app from your IDE, but will remain external from your jar in your final distribution).

keyCode and which represent the actual keyboard key pressed in the form of a numeric value. The reason both exist is that keyCode is available within Internet Explorer while which is available in W3C browsers like FireFox.

charCode is similar, but in this case you retrieve the Unicode value of the character pressed. For example, the letter "A."

The JavaScript expression:

var keyCode = e.keyCode ? e.keyCode : e.charCode;

Essentially says the following:

If the e.keyCode property exists, set variable keyCode to its value. Otherwise, set variable keyCode to the value of the e.charCode property.

Note that retrieving the keyCode or charCode properties typically involve figuring out differences between the event models in IE and in W3C. Some entails writing code like the following:

/*
 get the event object: either window.event for IE 
 or the parameter e for other browsers
*/
var evt = window.event ? window.event : e;
/*
 get the numeric value of the key pressed: either 
 event.keyCode for IE for e.which for other browsers
*/
var keyCode = evt.keyCode ? evt.keyCode : e.which;

EDIT: Corrections to my explanation of charCode as per Tor Haugen's comments.

2018 already... I've found this fantastic online tool http://mapshaper.org/ to convert from ESRI shapefiles to SVG, TopoJSON, GeoJSON.

Here is the explanation of how to use it https://www.statsilk.com/maps/convert-esri-shapefile-map-geojson-format

Fast and straightforward! :)

You need to do two things:

1. Rename and re-order the factor levels before the plot
2. Rename the title of each legend to the same title

The code:

dtt$model <- factor(dtt$model, levels=c("mb", "ma", "mc"), labels=c("MBB", "MAA", "MCC"))

library(ggplot2)
ggplot(dtt, aes(x=year, y=V, group = model, colour = model, ymin = lower, ymax = upper)) +
  geom_ribbon(alpha = 0.35, linetype=0)+ 
  geom_line(aes(linetype=model), size = 1) +       
  geom_point(aes(shape=model), size=4)  +      
  theme(legend.position=c(.6,0.8)) +
  theme(legend.background = element_rect(colour = 'black', fill = 'grey90', size = 1, linetype='solid')) +
  scale_linetype_discrete("Model 1") +
  scale_shape_discrete("Model 1") +
  scale_colour_discrete("Model 1")

However, I think this is really ugly as well as difficult to interpret. It's far better to use facets:

ggplot(dtt, aes(x=year, y=V, group = model, colour = model, ymin = lower, ymax = upper)) +
  geom_ribbon(alpha=0.2, colour=NA)+ 
  geom_line() +       
  geom_point()  +      
  facet_wrap(~model)

I've solved that like this:

$RootPath = Split-Path (Split-Path $PSScriptRoot -Parent) -Parent

Alternatively you could also position the cursor onto the class name and press alt+enter (Show intention actions and quick fixes). It will suggest to Create Test.

At least works in IDEA version 12.

== is an equality test. It checks whether the right hand side and the left hand side are equal objects (according to their __eq__ or __cmp__ methods.)

is is an identity test. It checks whether the right hand side and the left hand side are the very same object. No methodcalls are done, objects can't influence the is operation.

You use is (and is not) for singletons, like None, where you don't care about objects that might want to pretend to be None or where you want to protect against objects breaking when being compared against None.

Looking at your Erlang implementation. The timing has included the start up of the entire virtual machine, running your program and halting the virtual machine. Am pretty sure that setting up and halting the erlang vm takes some time.

If the timing was done within the erlang virtual machine itself, results would be different as in that case we would have the actual time for only the program in question. Otherwise, i believe that the total time taken by the process of starting and loading of the Erlang Vm plus that of halting it (as you put it in your program) are all included in the total time which the method you are using to time the program is outputting. Consider using the erlang timing itself which we use when we want to time our programs within the virtual machine itself timer:tc/1 or timer:tc/2 or timer:tc/3. In this way, the results from erlang will exclude the time taken to start and stop/kill/halt the virtual machine. That is my reasoning there, think about it, and then try your bench mark again.

I actually suggest that we try to time the program (for languages that have a runtime), within the runtime of those languages in order to get a precise value. C for example has no overhead of starting and shutting down a runtime system as does Erlang, Python and Haskell (98% sure of this - i stand correction). So (based on this reasoning) i conclude by saying that this benchmark wasnot precise /fair enough for languages running on top of a runtime system. Lets do it again with these changes.

EDIT: besides even if all the languages had runtime systems, the overhead of starting each and halting it would differ. so i suggest we time from within the runtime systems (for the languages for which this applies). The Erlang VM is known to have considerable overhead at start up!

This is a very simple way of doing it with no functionality and all visual effect,

Use a grid and just simply customise it.

<Grid Background="DodgerBlue" Height="250" Width="1" VerticalAlignment="Center" Margin="5,0,5,0"/>

Just another way to do it.

Join string1 with string2 and use KMP algorithm to check whether string2 is present in newly formed string. Because time complexity of KMP is lesser than substr.

Try this for SQL Server:

WITH cte AS (
   SELECT home, MAX(year) AS year FROM Table1 GROUP BY home
)
SELECT * FROM Table1 a INNER JOIN cte ON a.home = cte.home AND a.year = cte.year

nor does it appear in the list of environments that can be added when I click the "Add" button. All I see is the J2EE Runtime Library.

Go get "Eclipse for Java EE developers". Note the extra "EE". This includes among others the Web Tools Platform with among others a lot of server plugins with among others the one for Apache Tomcat 5.x. It's also logically; JSP/Servlet is part of the Java EE API.

mod_rewrite can only rewrite/redirect requested URIs. So you would need to request /apple/… to get it rewritten to a corresponding /folder1/….

Try this:

RewriteEngine on
RewriteRule ^apple/(.*) folder1/$1

This rule will rewrite every request that starts with the URI path /apple/… internally to /folder1/….

Edit    As you are actually looking for the other way round:

RewriteCond %{THE_REQUEST} ^GET\ /folder1/
RewriteRule ^folder1/(.*) /apple/$1 [L,R=301]

This rule is designed to work together with the other rule above. Requests of /folder1/… will be redirected externally to /apple/… and requests of /apple/… will then be rewritten internally back to /folder1/….

If the given solutions does not work, create a new project with 'KOTLIN' as the language even if your work is on java. Then replace the 'main' folder of the new project with the 'main' folder of the old.

Rico Mariani, the .NET Performance guru, had an article on this very subject. It's not as simple as one might suspect. The basic advice is this:

If your pattern looks like:

x = f1(...) + f2(...) + f3(...) + f4(...)

that's one concat and it's zippy, StringBuilder probably won't help.

If your pattern looks like:

if (...) x += f1(...)
if (...) x += f2(...)
if (...) x += f3(...)
if (...) x += f4(...)

then you probably want StringBuilder.

Yet another article to support this claim comes from Eric Lippert where he describes the optimizations performed on one line + concatenations in a detailed manner.

Another approach using vim would be:

:g/KEY/join

This applies a join (to the line below it) to all lines that have the word KEY in it. Result:

KEY 4048:1736 string 3
KEY 0:1772 string 1
KEY 4192:1349 string 1
KEY 7329:2407 string 2
KEY 0:1774 string 1

If you've not pushed either commit to your remote repository, you could use interactive rebasing to 'reorder' your commits and stash the (new) most recent commit's changes only.

Assuming you have the tip of your current branch (commit 111 in your example) checked out, execute the following:

git rebase -i HEAD~2

This will open your default editor, listing most recent 2 commits and provide you with some instructions. Be very cautious as to what you do here, as you are going to effectively 'rewrite' the history of your repository, and can potentially lose work if you aren't careful (make a backup of the whole repository first if necessary). I've estimated commit hashes/titles below for example

pick 222 commit to be stashed
pick 111 commit to be pushed to remote

# Rebase 111..222 onto 333
#
# Commands:
#  p, pick = use commit
#  r, reword = use commit, but edit the commit message
#  e, edit = use commit, but stop for amending
#  s, squash = use commit, but meld into previous commit
#  f, fixup = like "squash", but discard this commit's log message
#  x, exec = run command (the rest of the line) using shell
#
# These lines can be re-ordered; they are executed from top to bottom.
#
# If you remove a line here THAT COMMIT WILL BE LOST.
#
# However, if you remove everything, the rebase will be aborted.
#
# Note that empty commits are commented out

Reorder the two commits (they are listed oldest => newest) like this:

pick 111 commit to be pushed to remote
pick 222 commit to be stashed

Save and exit, at which point git will do some processing to rewrite the two commits you have changed. Assuming no issues, you should have reversed the order of your two changesets. This can be confirmed with git log --oneline -5 which will output newest-first.

At this point, you can simply do a soft-reset on the most recent commit, and stash your working changes:

git reset --soft HEAD~1
git stash

It's important to mention that this option is only really viable if you have not previously pushed any of these changes to your remote, otherwise it can cause issues for everyone using the repository.

First of all, move all your PHP code to the top. Without it, my code below wont work.

To do the redirect, use:

header('Location: http://www.example.com/');

Also, please consider my advice. Since it's not the first question today and all your questions are related to basics, you should consider reading some good PHP book to understand how things work.

Here you can find useful links to free books: https://stackoverflow.com/tags/php/info

If you have more numbers or if you intend to add new test numbers for CASE then you can use a more flexible approach:

DECLARE @Numbers TABLE
(
    Number VARCHAR(50) PRIMARY KEY
    ,Class TINYINT NOT NULL
);
INSERT @Numbers
VALUES ('1121231',1);
INSERT @Numbers
VALUES ('31242323',1);
INSERT @Numbers
VALUES ('234523',2);
INSERT @Numbers
VALUES ('2342423',2);

SELECT c.*, n.Class
FROM   tblClient c  
LEFT OUTER JOIN   @Numbers n ON c.Number = n.Number;

Also, instead of table variable you can use a regular table.

Here's an alternative solution using requests:

import requests
wjdata = requests.get('url').json()
print wjdata['data']['current_condition'][0]['temp_C']

Since I just lost two days of my life trying to solve for tryCatch for an irr function, I thought I should share my wisdom (and what is missing). FYI - irr is an actual function from FinCal in this case where got errors in a few cases on a large data set.

1. Set up tryCatch as part of a function. For example:

   irr2 <- function (x) {
     out <- tryCatch(irr(x), error = function(e) NULL)
     return(out)
   }
   

2. For the error (or warning) to work, you actually need to create a function. I originally for error part just wrote error = return(NULL) and ALL values came back null.

3. Remember to create a sub-output (like my "out") and to return(out).

You could probably try this to get file sizes in kB and MB Until the file size in bytes would be upto 7 digits, the outcome would be in kbs. 7 seems to be the magic number here. After which, if the bytes would have 7 to 10 digits, we would have to divide it by 10**3(n) where n is the appending action . This pattern would repeat for every 3 digits added.

let fileSize = myInp.files[0].size.toString();

if(fileSize.length < 7) return `${Math.round(+fileSize/1024).toFixed(2)}kb`
    return `${(Math.round(+fileSize/1024)/1000).toFixed(2)}MB`

Why not try IIF function (requires SQL Server 2012 and later)

IIF(a>b, a, b)

That's it.

(Hint: be careful about either would be null, since the result of a>b will be false whenever either is null. So b will be the result in this case)

<a ngHref="/path/{{obj.val1}}/{{obj.val2}}">{{obj.val1}}, {{obj.val2}}</a>

Here's an example - we recently developed a simulation model to measure the remote transmission response time of a yet-to-be-developed system. An emulation analysis would not have given us the answer in time to upgrade the bandwidth capacity so simulation was our approach. Because we were mostly interested in determining bandwidth needs, we cared primarily about transaction size and volume, not the processing of the system. The simulation model was on a stand-alone piece of software that was designed to model discrete-event processes. To summarize in response to your question, emulation is a type of simulation. But, in this case, simulation was NOT an emulation because it didn't fully represent the new system, only the size and volume of transactions.

Refer to Section 8.3 of this SAML core pdf of oasis SAML specification.

SP and IdP usually communicate each other about a subject. That subject should be identified through a NAME-IDentifier , which should be in some format so that It is easy for the other party to identify it based on the Format.

All these

1.urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified [default]

2.urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress

3.urn:oasis:names:tc:SAML:2.0:nameid-format:persistent

4.urn:oasis:names:tc:SAML:2.0:nameid-format:transient

are format for the Name Identifiers.

The name format for a transient ID in SAML 1 is urn:mace:shibboleth:1.0:nameIdentifier and in SAML 2 is urn:oasis:names:tc:SAML:2.0:nameid-format:transient

Transient is for [section 8.3.8 of SAML Core]

Indicates that the content of the element is an identifier with transient semantics and SHOULD be treated as an opaque and temporary value by the relying party.

Unspecified can be used and it purely depends on the entities implementation on their own wish.

X = np.array([[1., 0.], [2., 1.], [0., 0.]])
y = np.array([0, 1, 2])
from sklearn.utils import shuffle
X, y = shuffle(X, y, random_state=0)

To increase security even more, You can have md5 encryption along with two different salt strings, one static salt defined in php file and then one more randomly generated unique salt for each password record.

Here is how you can generate salt, md5 string and store:

    $unique_salt_string = hash('md5', microtime()); 
    $password = hash('md5', $_POST['password'].'static_salt'.$unique_salt_string);
    $query = "INSERT INTO users (username,password,salt) VALUES('bob','".$password."', '".$unique_salt_string."');

Now you have a static salt, which is valid for all your passwords, that is stored in the .php file. Then, at registration execution, you generate a unique hash for that specific password.

This all ends up with: two passwords that are spelled exactly the same, will have two different hashes. The unique hash is stored in the database along with the current id. If someone grab the database, they will have every single unique salt for every specific password. But what they don't have is your static salt, which make things a lot harder for every "hacker" out there.

This is how you check the validity of your password on login.php for example:

     $user = //username input;
     $db_query = mysql_query("SELECT salt FROM users WHERE username='$user'");
     while($salt = mysql_fetch_array($db_query)) {
            $password = hash('md5',$_POST['userpassword'].'static_salt'.$salt[salt]);
}

This method is very powerful and secure. If you want to use sha512 encryption, just to put that inside the hash function instead of md5 in above code.

I have faced this similar issue and resolved it by using following steps :

1. Open windows command prompt.
2. Login using the command sqlplus "/ as sysdba"
3. Then executed the command alter user HR identified by password account unlock
   
   Please note, the password is the password that I have used.
   
   By using above steps you can connect to Oracle Database as user HR with the password password.

As highlighted in other answer(s) we can simply use command git status and then look for files listed under Unmerged paths:

In case of you decided the debug your apk which is already in market but not assigned to be debuggable and you do not want to publish it again. So follow the below steps;

1. Decompile the Apk with ApkTool(eg. apktool d <APK_PATH>)
2. Open the AndroidManifest.xml from decompiled files
3. Set android:debuggable="true" in application tag
4. Compile the modified source with ApkTool (eg. apktool b <MODIFIED_PATH>)
5. Debuggable apk ready(which unsigned means cannot publish store). You can debug as you wish.

Might sound stupid, But Params doesn't allow multidimensional array. Whereas you can pass a multidimensional array to a function.

class Main {
    public static void main(String args[]) throws Exception {
        ApplicationContext ac = new
          ClassPathXmlApplicationContext("context.xml", Main.class);
        DataSource dataSource = (DataSource) ac.getBean("dataSource");
// DataSource mysqlDataSource = (DataSource) ac.getBean("mysqlDataSource");

        JdbcTemplate jdbcTemplate = new JdbcTemplate(dataSource);

        String prasobhName = 
        jdbcTemplate.query(
           "select first_name from customer where last_name like ?",
            new PreparedStatementSetter() {
              public void setValues(PreparedStatement preparedStatement) throws
                SQLException {
                  preparedStatement.setString(1, "nair%");
              }
            }, 
            new ResultSetExtractor<Long>() {
              public Long extractData(ResultSet resultSet) throws SQLException,
                DataAccessException {
                  if (resultSet.next()) {
                      return resultSet.getLong(1);
                  }
                  return null;
              }
            }
        );
        System.out.println(machaceksName);
    }
}

A one liner that takes into account empty lists would be:

T lastItem = list.size() == 0 ? null : list.get(list.size() - 1);

Or if you don't like null values (and performance isn't an issue):

Optional<T> lastItem = list.stream().reduce((first, second) -> second);

The above answers using layout_didn't work for me, but the following did.

in my own case in django 1.10.1 running on python2.7.11, I was trying to start the server using django-admin runserver instead of manage.py runserver in my project directory.

First check the variables declared using proper Datatypes. I had a same problem then I have checked, by mistake I declared SAPUser as int datatype so that the error occurred. One more thing XML file stores its data using concept like array but its first index starts having +1. e.g. if error is in(7,2) then check for 6th line always.....

Since none of the above solve my issue, I will post my solution

WARNING: if you just installed TensorFlow using conda, you have to restart your command prompt!

Solution: restart terminal ENTIRELY and restart conda environment

Some other service may be using port 80: try to stop the other services: HTTPD, SSL, NGINX, PHP, with the command sudo systemctl stop and then use the command sudo systemctl start httpd

You need to put the format arguments into a tuple (add parentheses):

instr = "'%s', '%s', '%d', '%s', '%s', '%s', '%s'" % (softname, procversion, int(percent), exe, description, company, procurl)

What you currently have is equivalent to the following:

intstr = ("'%s', '%s', '%d', '%s', '%s', '%s', '%s'" % softname), procversion, int(percent), exe, description, company, procurl

Example:

>>> "%s %s" % 'hello', 'world'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: not enough arguments for format string
>>> "%s %s" % ('hello', 'world')
'hello world'

I would first want to know what you are trying to accomplish here to need an argument to be passed to new Runnable() or to run(). The usual way should be to have a Runnable object which passes data(str) to its threads by setting member variables before starting. The run() method then uses these member variable values to do execute someFunc()

Here are some ways to edit the text and the size of the box:

rows="insertNumber"
cols="insertNumber"
style="font-size:12pt"

Example:

<textarea rows="5" cols="30" style="font-size: 12pt" id="myText">Enter 
Text Here</textarea>

You might have a lower project language level than your JDK.

Check if: "Projeckt structure/project/Project-> language level" is lower than your JDK. I had the same problem with JDK 9 and the language level was per default set to 6.

I set the Project Language Level to 9 and everything worked fine after that.

You might have the same issue.

This can be done in a generic way and can be very useful when debugging a complex makefile. Following the same technique as described in another answer, you can insert the following into any makefile:

# if the first command line argument is "print"
ifeq ($(firstword $(MAKECMDGOALS)),print)

  # take the rest of the arguments as variable names
  VAR_NAMES := $(wordlist 2,$(words $(MAKECMDGOALS)),$(MAKECMDGOALS))

  # turn them into do-nothing targets
  $(eval $(VAR_NAMES):;@:))

  # then print them
  .PHONY: print
  print:
          @$(foreach var,$(VAR_NAMES),\
            echo '$(var) = $($(var))';)
endif

Then you can just do "make print" to dump the value of any variable:

$ make print CXXFLAGS
CXXFLAGS = -g -Wall

Use the time.Now() function and the time.Format() method.

t := time.Now()
fmt.Println(t.Format("20060102150405"))

prints out 20110504111515, or at least it did a few minutes ago. (I'm on Eastern Daylight Time.) There are several pre-defined time formats in the constants defined in the time package.

You can use time.Now().UTC() if you'd rather have UTC than your local time zone.

This will list all certificates:

keytool -list -keystore "$JAVA_HOME/jre/lib/security/cacerts"

mydate = datetime.datetime.now()
mydate.strftime("%B") # 'December'
mydate.strftime("%b") # 'dec'

try this

if you don't have bc installed, try

echo $(( $(... | paste -sd+ -) ))

instead of

... | paste -sd+ - | bc

$( ) <-- return the value of executing the command

$(( 1+2 )) <-- return the evaluated results

echo <-- echo it to the screen

In wind32, console-mode applications are a completely different beast from the usual message-queue-receiving applications. They are declared and compile differently. You might create an application which has both a console part and normal window and hide one or the other. But suspect you will find the whole thing a bit more work than you thought.

For .NET 2.0, here's a nice bit of code I wrote that does exactly what you want, and works for any property on a Control:

private delegate void SetControlPropertyThreadSafeDelegate(
    Control control, 
    string propertyName, 
    object propertyValue);

public static void SetControlPropertyThreadSafe(
    Control control, 
    string propertyName, 
    object propertyValue)
{
  if (control.InvokeRequired)
  {
    control.Invoke(new SetControlPropertyThreadSafeDelegate               
    (SetControlPropertyThreadSafe), 
    new object[] { control, propertyName, propertyValue });
  }
  else
  {
    control.GetType().InvokeMember(
        propertyName, 
        BindingFlags.SetProperty, 
        null, 
        control, 
        new object[] { propertyValue });
  }
}

Call it like this:

// thread-safe equivalent of
// myLabel.Text = status;
SetControlPropertyThreadSafe(myLabel, "Text", status);

If you're using .NET 3.0 or above, you could rewrite the above method as an extension method of the Control class, which would then simplify the call to:

myLabel.SetPropertyThreadSafe("Text", status);

UPDATE 05/10/2010:

For .NET 3.0 you should use this code:

private delegate void SetPropertyThreadSafeDelegate<TResult>(
    Control @this, 
    Expression<Func<TResult>> property, 
    TResult value);

public static void SetPropertyThreadSafe<TResult>(
    this Control @this, 
    Expression<Func<TResult>> property, 
    TResult value)
{
  var propertyInfo = (property.Body as MemberExpression).Member 
      as PropertyInfo;

  if (propertyInfo == null ||
      [email protected]().IsSubclassOf(propertyInfo.ReflectedType) ||
      @this.GetType().GetProperty(
          propertyInfo.Name, 
          propertyInfo.PropertyType) == null)
  {
    throw new ArgumentException("The lambda expression 'property' must reference a valid property on this Control.");
  }

  if (@this.InvokeRequired)
  {
      @this.Invoke(new SetPropertyThreadSafeDelegate<TResult> 
      (SetPropertyThreadSafe), 
      new object[] { @this, property, value });
  }
  else
  {
      @this.GetType().InvokeMember(
          propertyInfo.Name, 
          BindingFlags.SetProperty, 
          null, 
          @this, 
          new object[] { value });
  }
}

which uses LINQ and lambda expressions to allow much cleaner, simpler and safer syntax:

myLabel.SetPropertyThreadSafe(() => myLabel.Text, status); // status has to be a string or this will fail to compile

Not only is the property name now checked at compile time, the property's type is as well, so it's impossible to (for example) assign a string value to a boolean property, and hence cause a runtime exception.

Unfortunately this doesn't stop anyone from doing stupid things such as passing in another Control's property and value, so the following will happily compile:

myLabel.SetPropertyThreadSafe(() => aForm.ShowIcon, false);

Hence I added the runtime checks to ensure that the passed-in property does actually belong to the Control that the method's being called on. Not perfect, but still a lot better than the .NET 2.0 version.

If anyone has any further suggestions on how to improve this code for compile-time safety, please comment!

You have #include "fun.cpp" in mainfile.cpp so compiling with:

g++ -o hw1 mainfile.cpp

will work, however if you compile by linking these together like

g++ -g -std=c++11 -Wall -pedantic   -c -o fun.o fun.cpp
g++ -g -std=c++11 -Wall -pedantic   -c -o mainfile.o mainfile.cpp

As they mention above, adding #include "fun.hpp" will need to be done or it won't work. However, your case with the funct() function is slightly different than my problem.

I had this issue when doing a HW assignment and the autograder compiled by the lower bash recipe, yet locally it worked using the upper bash.

$('#mytable tr').each(function() {
  // need this to skip the first row
  if ($(this).find("td:first").length > 0) {
    var cutomerId = $(this).find("td:first").html();
  }
});

I had a directory of files that I wanted to check. I created an Excel macro to determine ANSI vs. UTF-8. This worked for me.

Here is a quick and dirty way to extract the code from V3 or V4 ipynb without using ipython. It does not check cell types, etc.

import sys,json

f = open(sys.argv[1], 'r') #input.ipynb
j = json.load(f)
of = open(sys.argv[2], 'w') #output.py
if j["nbformat"] >=4:
        for i,cell in enumerate(j["cells"]):
                of.write("#cell "+str(i)+"\n")
                for line in cell["source"]:
                        of.write(line)
                of.write('\n\n')
else:
        for i,cell in enumerate(j["worksheets"][0]["cells"]):
                of.write("#cell "+str(i)+"\n")
                for line in cell["input"]:
                        of.write(line)

of.close()

You can convert a datetime object to a date with the date() method of the date time object, as follows:

<datetime_object>.date()

I never understood why this makes a difference for the compiler, but this is sufficient.

{
    public static void Invoke(this Control control, Action action)
    {
        control.Invoke(action);
    }
}

Bonus: add some error handling, because it is likely that, if you are using Control.Invoke from a background thread you are updating the text / progress / enabled state of a control and don't care if the control is already disposed.

public static class ControlExtensions
{
    public static void Invoke(this Control control, Action action)
    {
        try
        {
            if (!control.IsDisposed) control.Invoke(action);
        }
        catch (ObjectDisposedException) { }
    }
}

Old question perhaps here but I had the issue and the solution was easy and simple, I found this http://www.c-sharpcorner.com/UploadFile/mahesh/1220/

It makes use of the databining and works nicely so check it out.

Edit: Other answers are better, see comments.

I solved the same problem this way:

...
render : function () {
  var componentToRender = 'component1Name';
  var componentLookup = {
    component1Name : (<Component1 />),
    component2Name : (<Component2 />),
    ...
  };
  return (<div>
    {componentLookup[componentToRender]}
  </div>);
}
...

I'm really late to party here, but most of the answers seem to be about the whys and whens of using assertions in general, rather than using AssertionError in particular.

assert and throw new AssertionError() are very similar and serve the same conceptual purpose, but there are differences.

1. throw new AssertionError() will throw the exception regardless of whether assertions are enabled for the jvm (i.e., through the -ea switch).
2. The compiler knows that throw new AssertionError() will exit the block, so using it will let you avoid certain compiler errors that assert will not.

For example:

    {
        boolean b = true;
        final int n;
        if ( b ) {
            n = 5;
        } else {
            throw new AssertionError();
        }
        System.out.println("n = " + n);
    }

    {
        boolean b = true;
        final int n;
        if ( b ) {
            n = 5;
        } else {
            assert false;
        }
        System.out.println("n = " + n);
    }

The first block, above, compiles just fine. The second block does not compile, because the compiler cannot guarantee that n has been initialized by the time the code tries to print it out.

Did you tried to just delete the 4.3 SDK from within the Xcode Package?

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs

please also delete the corresponding .dmg file in

~/Library/Caches/com.apple.dt.Xcode/Downloads

to prevent Xcode from re-installing the same package again.

for XCode >= 6 see @praveen-matanam 's answer

const

public const string MyStr;

is a compile time constant (you can use it as the default parameter for a method parameter for example), and it will not be obfuscated if you use such technology

static readonly

public static readonly string MyStr;

is runtime constant. It means that it is evaluated when the application is launched and not before. This is why it can't be used as the default parameter for a method (compilation error) for example. The value stored in it can be obfuscated.

To checkout the branch via Jenkins scripts use:

stage('Checkout SCM') {
    git branch: 'branchName', credentialsId: 'your_credentials', url: "giturlrepo"
}

I have modified one of the answers (by @op1ekun):

123-(apple(?=-)|banana(?=-)|(?!-))-?456

The reason is that the answer from @op1ekun also matches "123-apple456", without the hyphen after apple.

public void ConfigureServices(IServiceCollection services)
{
    services.AddCors(options =>

    services.Configure<MvcOptions>(options => {
        options.Filters.Add(new CorsAuthorizationFilterFactory("AllowAnyOrigin"));
    });

I have done it using the following code,

glBegin(GL.GL_LINE_LOOP);
     for(int i =0; i <= 300; i++){
         double angle = 2 * Math.PI * i / 300;
         double x = Math.cos(angle);
         double y = Math.sin(angle);
         gl.glVertex2d(x,y);
     }
glEnd();

My problem/solution is very embarrassing but who knows... perhaps it happened to someone else:

My solution: Turn off proxy

For the past two hours I've been wondering why my manager would not load. (the root was cached so it loaded). I had set the browser's proxy to proxy traffic to my house. :/

To answer to your second question. You can just hit the IP address of the machine that your flask app is running, e.g. 192.168.1.100 in a browser on different machine on the same network and you are there. Though, you will not be able to access it if you are on a different network. Firewalls or VLans can cause you problems with reaching your application. If that computer has a public IP, then you can hit that IP from anywhere on the planet and you will be able to reach the app. Usually this might impose some configuration, since most of the public servers are behind some sort of router or firewall.

Here is what made the error disappear for me:

Close eclipse, open up a terminal window and run:

$ mvn clean eclipse:clean eclipse:eclipse

Are you using Maven? If so,

1. Right-click on the project, Build Path and go to Configure Build Path
2. Click the libraries tab. If Maven dependencies are not in the list, you need to add it.
3. Close the dialog.

To add it: Right-click on the project, Maven → Disable Maven Nature Right-click on the project, Configure → Convert to Maven Project.

And then clean

Edit 1:

If that doesn't resolve the issue try right-clicking on your project and select properties. Select Java Build Path → Library tab. Look for a JVM. If it's not there, click to add Library and add the default JVM. If VM is there, click edit and select the default JVM. Hopefully, that works.

Edit 2:

You can also try going into the folder where you have all your projects and delete the .metadata for eclipse (be aware that you'll have to re-import all the projects afterwards! Also all the environment settings you've set would also have to be redone). After it was deleted just import the project again, and hopefully, it works.

A parse exception is a checked exception, so you must catch it with a try-catch when working with parsing Strings to Dates, as @miku suggested...

If you are familiar with using System.Windows.Forms class then you can just add a reference of System.Windows.Forms class to your project:

Solution Explorer -> References -> Add References... -> ( Assemblies : Framework ) -> scroll down and check System.Windows.Forms assembly -> OK.

Now you can add using System.Windows.Forms; statement and use screen in your wpf project just like before.

you can do that (work in mysql) probably other SQL too.. just try this:

select * from table where concat(' ',first_name,last_name) 
    like '%$search_term%';

Try adding a reference to the missing dll's from your service/web project directly. Adding the references to a different project didn't work for me.

I only had to do this when publishing my web app because it wasn't copying all the required dll's.

Here are two methods, one sweet and simple(and conceptual), the other more formal and can be extended in a variety of situations, after having read a dataset.

Method 1: Conceptual

X2=[]
X1=[1,2,3]
X2.append(X1)
X3=[4,5,6]
X2.append(X3)
X2 thus has [[1,2,3],[4,5,6]] ie a list of lists. 

Method 2 : Formal and extensible

Another elegant way to store a list as a list of lists of different numbers - which it reads from a file. (The file here has the dataset train) Train is a data-set with say 50 rows and 20 columns. ie. Train[0] gives me the 1st row of a csv file, train[1] gives me the 2nd row and so on. I am interested in separating the dataset with 50 rows as one list, except the column 0 , which is my explained variable here, so must be removed from the orignal train dataset, and then scaling up list after list- ie a list of a list. Here's the code that does that.

Note that I am reading from "1" in the inner loop since I am interested in explanatory variables only. And I re-initialize X1=[] in the other loop, else the X2.append([0:(len(train[0])-1)]) will rewrite X1 over and over again - besides it more memory efficient.

X2=[]
for j in range(0,len(train)):
    X1=[]
    for k in range(1,len(train[0])):
        txt2=train[j][k]
        X1.append(txt2)
    X2.append(X1[0:(len(train[0])-1)])

From the HERE and HERE

public File getFilesDir ()

Returns the absolute path to the directory on the filesystem where files created with openFileOutput(String, int) are stored.

public static File getExternalStorageDirectory ()

Return the primary external storage directory. This directory may not currently be accessible if it has been mounted by the user on their computer, has been removed from the device, or some other problem has happened. You can determine its current state with getExternalStorageState().

Note: don't be confused by the word "external" here. This directory can better be thought as media/shared storage. It is a filesystem that can hold a relatively large amount of data and that is shared across all applications (does not enforce permissions). Traditionally this is an SD card, but it may also be implemented as built-in storage in a device that is distinct from the protected internal storage and can be mounted as a filesystem on a computer.

On devices with multiple users (as described by UserManager), each user has their own isolated external storage. Applications only have access to the external storage for the user they're running as.

If you want to get your application path use getFilesDir() which will give you path /data/data/your package/files

You can get the path using the Environment var of your data/package using the

getExternalFilesDir(Environment.getDataDirectory().getAbsolutePath()).getAbsolutePath(); which will return the path from the root directory of your external storage as /storage/sdcard/Android/data/your pacakge/files/data

To access the external resources you have to provide the permission of WRITE_EXTERNAL_STORAGE and READ_EXTERNAL_STORAGE in your manifest.

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

Check out the Best Documentation to get the paths of direcorty

I'd probably split the long statement up into multiple shorter statements so that the program logic is separated from the definition of the long string:

>>> def fun():
...     format_string = '{0} Here is a really long ' \
...                     'sentence with {1}'
...     print format_string.format(3, 5)

If the string is only just too long and you choose a short variable name then by doing this you might even avoid having to split the string:

>>> def fun():
...     s = '{0} Here is a really long sentence with {1}'
...     print s.format(3, 5)

Here is an iterative solution using object-scan. The advantage is that you can easily do other processing in the filter function and specify the paths in a more readable format. There is a trade-off in introducing a dependency though, so it really depends on your use case.

// const objectScan = require('object-scan');

const search = (haystack, k, v) => objectScan([`list[*].${k}`], {
  rtn: 'parent',
  filterFn: ({ value }) => value === v
})(haystack);

const obj = { list: [ { name: 'my Name', id: 12, type: 'car owner' }, { name: 'my Name2', id: 13, type: 'car owner2' }, { name: 'my Name4', id: 14, type: 'car owner3' }, { name: 'my Name4', id: 15, type: 'car owner5' } ] };

console.log(search(obj, 'name', 'my Name'));
// => [ { name: 'my Name', id: 12, type: 'car owner' } ]

The easiest way is to redirect the output of the echo by >>:

echo 'VNCSERVERARGS[1]="-geometry 1600x1200"' >> /etc/sysconfig/configfile

jQuery .on method is used to bind events even without the presence of element on page load. Here is the link It is used in this way:

 $("#dataTable tbody tr").on("click", function(event){
    alert($(this).text());
 });

Before jquery 1.7, .live() method was used, but it is deprecated now.

1. create table xyz_new as select * from xyz;

-- This will create table and copy all data.

2. delete from xyz_new;

-- This will have same table structure but all data copied will be deleted.

If you want to overcome the limitations specified by answer: How can I create a copy of an Oracle table without copying the data?

For anyone else having the same problem, I figured it out myself.

    <html>_x000D_
      <body>_x000D_
        <form target="_blank" action="https://website.com/action.php" method="POST">_x000D_
          <input type="hidden" name="fullname" value="Sam" />_x000D_
          <input type="hidden" name="city" value="Dubai&#32;" />_x000D_
          <input onclick="window.location.href = 'https://website.com/my-account';" type="submit" value="Submit request" />_x000D_
        </form>_x000D_
      </body>_x000D_
    </html>

All I had to do was add the target="_blank" attribute to inline on form to open the response in a new page and redirect the other page using onclick on the submit button.

Add System.Web.Extensions as a reference to your project

For Ref.

You need to iterate the 2d array in order to get the min value of each row, then you have to push any gotten min value to another array and finally you need to get the min value of the array where each min row value was pushed

def get_min_value(self, table):
    min_values = []
    for i in range(0, len(table)):
        min_value = min(table[i])
        min_values.append(min_value)

    return min(min_values)

function LastRowIndex(byval w as worksheet, byval col as variant) as long
  dim r as range

  set r = application.intersect(w.usedrange, w.columns(col))
  if not r is nothing then
    set r = r.cells(r.cells.count)

    if isempty(r.value) then
      LastRowIndex = r.end(xlup).row
    else
      LastRowIndex = r.row
    end if
  end if
end function

Usage:

? LastRowIndex(ActiveSheet, 5)
? LastRowIndex(ActiveSheet, "AI")

I personally use a tooltip to display additional information, so when someone hovers over the event they can view a longer descriptions. This example uses qTip, but any tooltip implementation would work.

$(document).ready(function() {
    var date = new Date();
    var d = date.getDate();
    var m = date.getMonth();
    var y = date.getFullYear();
    $('#calendar').fullCalendar({
        header: {
            left: 'prev, next today',
            center: 'title',
            right: 'month, basicWeek, basicDay'
        },
        //events: "Calendar.asmx/EventList",
        //defaultView: 'dayView',
        events: [
        {
            title: 'All Day Event',
            start: new Date(y, m, 1),
            description: 'long description',
            id: 1
        },
        {
            title: 'Long Event',
            start: new Date(y, m, d - 5),
            end: new Date(y, m, 1),
            description: 'long description3',
            id: 2
        }],
        eventRender: function(event, element) {
            element.qtip({
                content: event.description + '<br />' + event.start,
                style: {
                    background: 'black',
                    color: '#FFFFFF'
                },
                position: {
                    corner: {
                        target: 'center',
                        tooltip: 'bottomMiddle'
                    }
                }
            });
        }
    });
});

I was/am in the same boat as you for different reasons (partly educational, partly constraints). I had to re-write all the containers of the standard library and the containers had to conform to the standard. That means, if I swap out my container with the stl version, the code would work the same. Which also meant that I had to re-write the iterators.

Anyway, I looked at EASTL. Apart from learning a ton about containers that I never learned all this time using the stl containers or through my undergraduate courses. The main reason is that EASTL is more readable than the stl counterpart (I found this is simply because of the lack of all the macros and straight forward coding style). There are some icky things in there (like #ifdefs for exceptions) but nothing to overwhelm you.

As others mentioned, look at cplusplus.com's reference on iterators and containers.

If you know your way around Java, you can use SvnKit to do browse, search and God knows what with your Subversion server.

After that, you can package your program and invoke it either via an Ant task or a shell script.

It's quite a "brute force" solution, but once you master SvnKit, you can really do lots of cool things.

In addition to Mathias answer.

Although not mentioned in OP, if you also need to see the Powershell specific/related internal variables, you need to use Get-Variable:

$ Get-Variable

?                              True
^                              gci
args                           {}

...

These also include stuff you may have set in your profile startup script.

On ng-build, file not found(404) error occur. So we can use below code

<ng-include src="'views/transaction/test.html'"></ng-include>

insted of,

<div ng-include="'views/transaction/test.html'"></div>

Your interior <div> elements should likely both be float:left. Divs size to 100% the size of their container width automatically. Try using display:inline-block instead of width:auto on the container div. Or possibly float:left the container and also apply overflow:auto. Depends on what you're after exactly.

The problem is that require does not load from the current directory. This is what I thought, too but then I found this thread. For example I tried the following code:

irb> f = File.new('blabla.rb')
=> #<File:blabla.rb>
irb> f.read
=> "class Tokenizer\n    def self.tokenize(string)\n        return string.split(
\" \")\n    end\nend\n"
irb> require f
LoadError: cannot load such file -- blabla.rb
        from D:/dev/Ruby193/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `req
uire'
        from D:/dev/Ruby193/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `req
uire'
        from (irb):24
        from D:/dev/Ruby193/bin/irb:12:in `<main>'

As it can be seen it read the file ok, but I could not require it (the path was not recognized). and here goes code that works:

irb f = File.new('D://blabla.rb')
=> #<File:D://blabla.rb>
irb f.read
=> "class Tokenizer\n    def self.tokenize(string)\n        return string.split(
\" \")\n    end\nend\n"
irb> require f
=> true

As you can see if you specify the full path the file loads correctly.

Here is some documentation that helps.

orphanRemoval has nothing to do with ON DELETE CASCADE.

orphanRemoval is an entirely ORM-specific thing. It marks "child" entity to be removed when it's no longer referenced from the "parent" entity, e.g. when you remove the child entity from the corresponding collection of the parent entity.

ON DELETE CASCADE is a database-specific thing, it deletes the "child" row in the database when the "parent" row is deleted.

Try this:

import React, { useCallback } from "react";
import { Linking } from "react-native";
OpenWEB = () => {
  Linking.openURL(url);
};

const App = () => {
  return <View onPress={() => OpenWeb}>OPEN YOUR WEB</View>;
};

Hope this will solve your problem.

Include a class example with the use keyword from Command Line Interface:

PHP Namespaces don't work on the commandline unless you also include or require the php file. When the php file is sitting in the webspace where it is interpreted by the php daemon then you don't need the require line. All you need is the 'use' line.

1. Create a new directory /home/el/bin

2. Make a new file called namespace_example.php and put this code in there:

   <?php
       require '/home/el/bin/mylib.php';
       use foobarwhatever\dingdong\penguinclass;
   
       $mypenguin = new penguinclass();
       echo $mypenguin->msg();
   ?>
   

3. Make another file called mylib.php and put this code in there:

   <?php
   namespace foobarwhatever\dingdong;
   class penguinclass 
   {
       public function msg() {
           return "It's a beautiful day chris, come out and play! " . 
                  "NO!  *SLAM!*  taka taka taka taka."; 
       }   
   }
   ?>   
   

4. Run it from commandline like this:

   el@apollo:~/bin$ php namespace_example.php 
   

5. Which prints:

   It's a beautiful day chris, come out and play!
   NO!  *SLAM!*  taka taka taka taka

The link below, gives a very good tutorial, about playing mp3 files from a windows form with c#:

http://www.daniweb.com/software-development/csharp/threads/292695/playing-mp3-in-c

This link will lead you to a topic, which contains a lot information about how to play an mp3 song, using Windows forms. It also contains a lot of other projects, trying to achieve the same thing:

http://social.msdn.microsoft.com/forums/en-US/csharpgeneral/thread/3dbfb9a3-4e14-41d1-afbb-1790420706fe

For example use this code for .mp3:

WMPLib.WindowsMediaPlayer wplayer = new WMPLib.WindowsMediaPlayer();

wplayer.URL = "My MP3 file.mp3";
wplayer.Controls.Play();

Then only put the wplayer.Controls.Play(); in the Button_Click event.

For example use this code for .wav:

System.Media.SoundPlayer player = new System.Media.SoundPlayer();

player.SoundLocation = "Sound.wav";
player.Play();

Put the player.Play(); in the Button_Click event, and it will work.

You could use an onclick event handler in order to get the input value for the text field. Make sure you give the field an unique id attribute so you can refer to it safely through document.getElementById():

If you want to dynamically add elements, you should have a container where to place them. For instance, a <div id="container">. Create new elements by means of document.createElement(), and use appendChild() to append each of them to the container. You might be interested in outputting a meaningful name attribute (e.g. name="member"+i for each of the dynamically generated <input>s if they are to be submitted in a form.

Notice you could also create <br/> elements with document.createElement('br'). If you want to just output some text, you can use document.createTextNode() instead.

Also, if you want to clear the container every time it is about to be populated, you could use hasChildNodes() and removeChild() together.

<html>
<head>
    <script type='text/javascript'>
        function addFields(){
            // Number of inputs to create
            var number = document.getElementById("member").value;
            // Container <div> where dynamic content will be placed
            var container = document.getElementById("container");
            // Clear previous contents of the container

                // Append a node with a random text
                container.appendChild(document.createTextNode("Member " + (i+1)));
                // Create an <input> element, set its type and name attributes

                input.name = "member" + i;
                container.appendChild(input);
                // Append a line break

This is how you can create a beautiful button with a bezel and rounded edges:

loginButton = UIButton(frame: CGRectMake(self.view.bounds.origin.x + (self.view.bounds.width * 0.325), self.view.bounds.origin.y + (self.view.bounds.height * 0.8), self.view.bounds.origin.x + (self.view.bounds.width * 0.35), self.view.bounds.origin.y + (self.view.bounds.height * 0.05)))
loginButton.layer.cornerRadius = 18.0
loginButton.layer.borderWidth = 2.0
loginButton.backgroundColor = UIColor.whiteColor()
loginButton.layer.borderColor = UIColor.whiteColor().CGColor
loginButton.setTitle("Login", forState: UIControlState.Normal)
loginButton.setTitleColor(UIColor(red: 24.0/100, green: 116.0/255, blue: 205.0/205, alpha: 1.0), forState: UIControlState.Normal)

Use the title attribute while alt is important for SEO stuff.

Some people may not like it, but this is what I do:

private void StartBackgroundWork() {
    if (Application.RenderWithVisualStyles)
        progressBar.Style = ProgressBarStyle.Marquee;
    else {
        progressBar.Style = ProgressBarStyle.Continuous;
        progressBar.Maximum = 100;
        progressBar.Value = 0;
        timer.Enabled = true;
    }
    backgroundWorker.RunWorkerAsync();
}

private void timer_Tick(object sender, EventArgs e) {
    if (progressBar.Value < progressBar.Maximum)
        progressBar.Increment(5);
    else
        progressBar.Value = progressBar.Minimum;
}

The Marquee style requires VisualStyles to be enabled, but it continuously scrolls on its own without needing to be updated. I use that for database operations that don't report their progress.

I suppose that you are using an array to create your select form input. In that case, use an array:

<?php
    $selected = array( $_REQUEST['yesnofine'] => 'selected="selected"' );
    $fields = array(1 => 'Yes', 2 => 'No', 3 => 'Fine');
 ?>
  <select name=‘yesnofine'>
 <?php foreach ($fields as $k => $v): ?>
  <option value="<?php echo $k;?>" <?php @print($selected[$k]);?>><?php echo $v;?></options>
 <?php endforeach; ?>
 </select>

If not, you may just unroll the above loop, and still use an array.

 <option value="1" <?php @print($selected[$k]);?>>Yes</options>
 <option value="2" <?php @print($selected[$k]);?>>No</options>
 <option value="3" <?php @print($selected[$k]);?>>Fine</options>

Notes that I don't know:

• how you are naming your input, so I made up a name for it.
• which way you are handling your form input on server side, I used $_REQUEST,

You will have to adapt the code to match requirements of the framework you are using, if any.

Also, it is customary in many frameworks to use the alternative syntax in view dedicated scripts.

That defeats the purpose of non-blocking IO -- you're blocking it when it doesn't need blocking :)

You should nest your callbacks instead of forcing node.js to wait, or call another callback inside the callback where you need the result of r.

Chances are, if you need to force blocking, you're thinking about your architecture wrong.

How are you importing ClassA into your AppDelegate Class? Did you include the .h file in the main project? I had this problem for a while because I didn't copy the header file into the main project as well as the normal #include "ClassA.h."

Copying, or creating the .h solved it for me.

Select yesterday to check past days or not with help of moment().subtract(1, "day");

You can do it by controlling the width of a div via css. Something roughly along these lines:

<div id="container" style="width:100%; height:50px; border:1px solid black;">
  <div id="progress-bar" style="width:50%;/*change this width */
       background-image:url(someImage.png);
       height:45px;">
  </div>
</div>

That width value can be sent in from php if you so desire.

This error would happen when the number of guesses (so_far) is less than the length of the word. Did you miss an initialization for the variable so_far somewhere, that sets it to something like

so_far = " " * len(word)

?

Edit:

try something like

print "%d / %d" % (new, so_far)

before the line that throws the error, so you can see exactly what goes wrong. The only thing I can think of is that so_far is in a different scope, and you're not actually using the instance you think.

I also think having a separate "version" for normal execution and as a service is the way to go, but is it really required to dedicate a separate command line switch for that purpose?

Couldn't you just do:

public static int Main(string[] args)
{
  if (!Environment.UserInteractive)
  {
    // Startup as service.
  }
  else
  {
    // Startup as application
  }
}

That would have the "benefit", that you can just start your app via doubleclick (OK, if you really need that) and that you can just hit F5 in Visual Studio (without the need to modify the project settings to include that /console Option).

Technically, the Environment.UserInteractive checks if the WSF_VISIBLE Flag is set for the current window station, but is there any other reason where it would return false, apart from being run as a (non-interactive) service?

You may get ORA-01031: insufficient privileges instead of ORA-00942: table or view does not exist when you have at least one privilege on the table, but not the necessary privilege.

Create schemas

SQL> create user schemaA identified by schemaA;

User created.

SQL> create user schemaB identified by schemaB;

User created.

SQL> create user test_user identified by test_user;

User created.

SQL> grant connect to test_user;

Grant succeeded.

Create objects and privileges

It is unusual, but possible, to grant a schema a privilege like DELETE without granting SELECT.

SQL> create table schemaA.table1(a number);

Table created.

SQL> create table schemaB.table2(a number);

Table created.

SQL> grant delete on schemaB.table2 to test_user;

Grant succeeded.

Connect as TEST_USER and try to query the tables

This shows that having some privilege on the table changes the error message.

SQL> select * from schemaA.table1;
select * from schemaA.table1
                      *

I had the same issue, but in my case chrome previously was installed in user temp folder, after that was reinstalled to Program files. So any of solution provided here was not help me. But if provide path to chrome.exe all works:

chromeOptions.setBinary("C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe");

I hope this helps someone =)

I suggest to use the inherits helper that comes with the standard util module: http://nodejs.org/api/util.html#util_util_inherits_constructor_superconstructor

There is an example of how to use it on the linked page.

Be sure you have C++ Redistributable for Visual Studio 2015 RC. Try to download the last version:

I have the same problem when installing a RaspberryPI TFT from Adafruit with pitft.sh / adafruit-pitft.sh.

I am not happy about coding-styles with errors from somewhere to be interpreted somehow - as could be seen by the previous answers.

Remark: The type error exception of retry.py is obviously a bug, caused by an unappropriate assignement and calculation of an instance of the class Reply to an int with the default value of 10 - somewhere in the code... Should be fixed either by adding an inplace-operator, or fixing the erroneous assignment.

So tried to analyse and patch the error itself first. The actual error in my case case is the same - retry.py called by pip.

The installation script adafruit-pitft.sh / pitft.sh tries to apply urllib3 which itself tries to install nested dependencies by pip, so the same error.

Could not find a version that satisfies the requirement evdev (from versions: )

No matching distribution found for evdev

WARNING : Pip failed to install software!

So in my case actually two things cause the error, this may vary in other environments:

1. Missing evdev => try to install
2. Failed to connect a repo/dist containing evdev in order to download. => finally give it up

My installation environment is offline from an internal debian+raspbian mirror, thus do not want to set the proxy...

So I proceeded by manual installation of the missing component evdev:

1. download evdev from PyPI(or e.g. from github.com):

   https://pypi.org/project/evdev/

   https://files.pythonhosted.org/packages/7e/53/374b82dd2ccec240b7388c65075391147524255466651a14340615aabb5f/evdev-1.1.2.tar.gz

2. Unpack and install manually as root user - for all local accounts, so detected as installed:

   sudo su -

   tar xf evdev-1.1.2.tar.gz

   cd evdev-1.1.2

   python setup.py install

3. Call install script again:

   adafruit-pitft.sh # or pitft.sh

   ...Answer dialogues...

   ...that's it.

If you proceed online by direct PyPI access:

1. check your routing + firewall for access to pypi.org

2. set a proxy if required (http_proxy/https_proxy)

And it works..

Hope this helps in other cases too.

It looks like not.

Put a breakpoint, when it stops switch to the console, try to set the variable. It does not error when you assign it a different value, but if you read it after the assignment, it's unmodified. :-/

If there are multiple white spaces in a string, then replace may not work correctly. For that, the following function should be used.

CREATE FUNCTION RemoveAllSpaces
(
    @InputStr varchar(8000)
)
RETURNS varchar(8000)
AS
BEGIN
declare @ResultStr varchar(8000)
set @ResultStr = @InputStr
while charindex(' ', @ResultStr) > 0
    set @ResultStr = replace(@InputStr, ' ', '')

return @ResultStr
END

Example:

select dbo.RemoveAllSpaces('aa  aaa       aa aa                 a')

Output:

aaaaaaaaaa

    function delimitNumbers(str) {
      return (str + "").replace(/\b(\d+)((\.\d+)*)\b/g, function(a, b, c) {
        return (b.charAt(0) > 0 && !(c || ".").lastIndexOf(".") ? b.replace(/(\d)(?=(\d{3})+$)/g, "$1,") : b) + c;
      });
    }

    alert(delimitNumbers(1234567890));

});

Insert mode

Movement

hjkl

Notwithstanding what Pavel Shved said - that it is probably more advisable to get used to Escaping Insert mode - here is an example set of mappings for quick navigation within Insert mode:

" provide hjkl movements in Insert mode via the <Alt> modifier key
inoremap <A-h> <C-o>h
inoremap <A-j> <C-o>j
inoremap <A-k> <C-o>k
inoremap <A-l> <C-o>l

This will make Alt+h in Insert mode go one character left, Alt+j down and so on, analogously to hjkl in Normal mode.

You have to copy that code into your vimrc file to have it loaded every time you start vim (you can open that by typing :new $myvimrc starting in Normal mode).

Any Normal mode movements

Since the Alt modifier key is not mapped (to something important) by default, you can in the same fashion pull other (or all) functionality from Normal mode to Insert mode. E.g.:
Moving to the beginning of the current word with Alt+b:

inoremap <A-b> <C-o>b
inoremap <A-w> <C-o>w

(Other uses of Alt in Insert mode)

It is worth mentioning that there may be better uses for the Alt key than replicating Normal mode behaviour: e.g. here are mappings for copying from an adjacent line the portion from the current column till the end of the line:

" Insert the rest of the line below the cursor.
" Mnemonic: Elevate characters from below line
inoremap <A-e> 
    \<Esc>
    \jl
        \y$
    \hk
        \p
        \a
" Insert the rest of the line above the cursor.
" Mnemonic: Y depicts a funnel, through which the above line's characters pour onto the current line.
inoremap <A-y> 
    \<Esc>
    \kl
        \y$
    \hj
        \p
        \a

(I used \ line continuation and indentation to increase clarity. The commands are interpreted as if written on a single line.)

Built-in hotkeys for editing

CTRL-H   delete the character  in front of the cursor (same as <Backspace>)
CTRL-W   delete the word       in front of the cursor
CTRL-U   delete all characters in front of the cursor (influenced by the 'backspace' option)

_{(There are no notable built-in hotkeys for movement in Insert mode.)}

Reference: :help insert-index

Command-line mode

This set of mappings makes the upper Alt+hjkl movements available in the Command-line:

" provide hjkl movements in Command-line mode via the <Alt> modifier key
cnoremap <A-h> <Left>
cnoremap <A-j> <Down>
cnoremap <A-k> <Up>
cnoremap <A-l> <Right>

Alternatively, these mappings add the movements both to Insert mode and Command-line mode in one go:

" provide hjkl movements in Insert mode and Command-line mode via the <Alt> modifier key
noremap! <A-h> <Left>
noremap! <A-j> <Down>
noremap! <A-k> <Up>
noremap! <A-l> <Right>

The mapping commands for pulling Normal mode commands to Command-line mode look a bit different from the Insert mode mapping commands (because Command-line mode lacks Insert mode's Ctrl+O):

" Normal mode command(s) go… --v <-- here
cnoremap <expr> <A-h> &cedit. 'h' .'<C-c>'
cnoremap <expr> <A-j> &cedit. 'j' .'<C-c>'
cnoremap <expr> <A-k> &cedit. 'k' .'<C-c>'
cnoremap <expr> <A-l> &cedit. 'l' .'<C-c>'

cnoremap <expr> <A-b> &cedit. 'b' .'<C-c>'
cnoremap <expr> <A-w> &cedit. 'w' .'<C-c>'

Built-in hotkeys for movement and editing

CTRL-B       cursor to beginning of command-line
CTRL-E       cursor to end       of command-line

CTRL-F       opens the command-line window (unless a different key is specified in 'cedit')

CTRL-H       delete the character  in front of the cursor (same as <Backspace>)
CTRL-W       delete the word       in front of the cursor
CTRL-U       delete all characters in front of the cursor

CTRL-P       recall previous command-line from history (that matches pattern in front of the cursor)
CTRL-N       recall next     command-line from history (that matches pattern in front of the cursor)
<Up>         recall previous command-line from history (that matches pattern in front of the cursor)
<Down>       recall next     command-line from history (that matches pattern in front of the cursor)
<S-Up>       recall previous command-line from history
<S-Down>     recall next     command-line from history
<PageUp>     recall previous command-line from history
<PageDown>   recall next     command-line from history

<S-Left>     cursor one word left
<C-Left>     cursor one word left
<S-Right>    cursor one word right
<C-Right>    cursor one word right

<LeftMouse>  cursor at mouse click

You just have to write sudo instead of su.

Then just copy the PHP file to the var/www/ directory.

Then go to the browser, and write local host/test.php or whatever the .php filename is.

Assuming the column is set to support NULL as a value:

UPDATE YOUR_TABLE
   SET column = NULL

Be aware of the database NULL handling - by default in SQL Server, NULL is an INT. So if the column is a different data type you need to CAST/CONVERT NULL to the proper data type:

UPDATE YOUR_TABLE
   SET column = CAST(NULL AS DATETIME)

...assuming column is a DATETIME data type in the example above.

The simplest way to do it is to do a depth first traversal (DFT) of the graph.

If the graph has n vertices, this is a O(n) time complexity algorithm. Since you will possibly have to do a DFT starting from each vertex, the total complexity becomes O(n^2).

You have to maintain a stack containing all vertices in the current depth first traversal, with its first element being the root node. If you come across an element which is already in the stack during the DFT, then you have a cycle.

extension Array where Element: Encodable {
    func asArrayDictionary() throws -> [[String: Any]] {
        var data: [[String: Any]] = []

        for element in self {
            data.append(try element.asDictionary())
        }
        return data
    }
}

extension Encodable {
        func asDictionary() throws -> [String: Any] {
            let data = try JSONEncoder().encode(self)
            guard let dictionary = try JSONSerialization.jsonObject(with: data, options: .allowFragments) as? [String: Any] else {
                throw NSError()
            }
            return dictionary
        }
}

If you're using Codable protocols in your models these extensions might be helpful for getting dictionary representation (Swift 4)

Can't you just try to replace the body content with the document.body handler?

if your page is this:

<html>
<body>
blablabla
<script type="text/javascript">
document.body.innerHTML="hi!";
</script>
</body>
</html>

Just use the document.body to replace the body.

This works for me. All the content of the BODY tag is replaced by the innerHTML you specify. If you need to even change the html tag and all childs you should check out which tags of the 'document.' are capable of doing so.

An example with javascript scripting inside it:

<html>
<body>
blablabla
<script type="text/javascript">
var changeme = "<button onClick=\"document.bgColor = \'#000000\'\">click</button>";
document.body.innerHTML=changeme;
</script>
</body>

This way you can do javascript scripting inside the new content. Don't forget to escape all double and single quotes though, or it won't work. escaping in javascript can be done by traversing your code and putting a backslash in front of all singe and double quotes.

Bare in mind that server side scripting like php doesn't work this way. Since PHP is server-side scripting it has to be processed before a page is loaded. Javascript is a language which works on client-side and thus can not activate the re-processing of php code.

Use:

var x = {
  'key': 1
};

if ('key' in x) {
  console.log('has');
}

The dependencies syntax is located at the Dependency Version Requirement Specification documentation. Here it is is for completeness:

Dependencies' version element define version requirements, used to compute effective dependency version. Version requirements have the following syntax:

• 1.0: "Soft" requirement on 1.0 (just a recommendation, if it matches all other ranges for the dependency)
• [1.0]: "Hard" requirement on 1.0
• (,1.0]: x <= 1.0
• [1.2,1.3]: 1.2 <= x <= 1.3
• [1.0,2.0): 1.0 <= x < 2.0
• [1.5,): x >= 1.5
• (,1.0],[1.2,): x <= 1.0 or x >= 1.2; multiple sets are comma-separated
• (,1.1),(1.1,): this excludes 1.1 (for example if it is known not to work in combination with this library)

In your case, you could do something like <version>[1.2.3,)</version>

You can also specify context location relatively to current classpath, which may be preferable

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath*:applicationContext*.xml</param-value>
</context-param>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

something like this

try 
{
  ...
}
catch (FooException e) 
{
  throw e;
}
catch (Exception e)
{
  ...
}

    if (GridViewSortDirection == SortDirection.Ascending)
    {
        GridViewSortDirection = SortDirection.Descending;
        SortGridView(sortExpression, DESCENDING);
    }
    else
    {
        GridViewSortDirection = SortDirection.Ascending;
        SortGridView(sortExpression, ASCENDING); 
    }   

}

private void SortGridView(string sortExpression,string direction)
{
    //  You can cache the DataTable for improving performance
    DataTable dt = GetData().Tables[0]; 

    DataView dv = new DataView(dt); 
    dv.Sort = sortExpression + direction;         

    GridView1.DataSource = dv;
    GridView1.DataBind();         
}

Why you don't want to use existing sorting functionality? You can always customize it.

What is the formatting I need to use to carry out conversion with Jackson? Is Date a good field type for this?

Date is a fine field type for this. You can make the JSON parse-able pretty easily by using ObjectMapper.setDateFormat:

DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm a z");
myObjectMapper.setDateFormat(df);

In general, is there a way to process the variables before they get mapped to Object members by Jackson? Something like, changing the format, calculations, etc.

Yes. You have a few options, including implementing a custom JsonDeserializer, e.g. extending JsonDeserializer<Date>. This is a good start.

You can try a rebase --interactive session to amend your old commit (provided you did not already push those commits to another repo).

Sometimes the thing fixed in b.2. cannot be amended to the not-quite perfect commit it fixes, because that commit is buried deeply in a patch series.
That is exactly what interactive rebase is for: use it after plenty of "a"s and "b"s, by rearranging and editing commits, and squashing multiple commits into one.

Start it with the last commit you want to retain as-is:

git rebase -i <after-this-commit>

An editor will be fired up with all the commits in your current branch (ignoring merge commits), which come after the given commit.
You can reorder the commits in this list to your heart's content, and you can remove them. The list looks more or less like this:

pick deadbee The oneline of this commit
pick fa1afe1 The oneline of the next commit
...

The oneline descriptions are purely for your pleasure; git rebase will not look at them but at the commit names ("deadbee" and "fa1afe1" in this example), so do not delete or edit the names.

By replacing the command "pick" with the command "edit", you can tell git rebase to stop after applying that commit, so that you can edit the files and/or the commit message, amend the commit, and continue rebasing.

Two options: 1, add css inline like style="background:black" Or 2. In the head include the css as a style tag block.

I might've over-engineered my own solution without realizing that Type.valueOf("enum string") actually existed.

I guess it gives more granular control but I'm not sure it's really necessary.

public enum Type {
    DEBIT,
    CREDIT;

    public static Map<String, Type> typeMapping = Maps.newHashMap();
    static {
        typeMapping.put(DEBIT.name(), DEBIT);
        typeMapping.put(CREDIT.name(), CREDIT);
    }

    public static Type getType(String typeName) {
        if (typeMapping.get(typeName) == null) {
            throw new RuntimeException(String.format("There is no Type mapping with name (%s)"));
        }
        return typeMapping.get(typeName);
    }
}

I guess you're exchanging IllegalArgumentException for RuntimeException (or whatever exception you wish to throw) which could potentially clean up code.

To get left and right tabs (now also with sideways) support for Bootstrap 3, bootstrap-vertical-tabs component can be used.

https://github.com/dbtek/bootstrap-vertical-tabs

Use arguments. You can access it like an array. Use arguments.length for the number of arguments.

Option 1: Put this in your procedure to print 'comment' to stdout when it runs.

SELECT 'Comment';

Option 2: Put this in your procedure to print a variable with it to stdout:

declare myvar INT default 0;
SET myvar = 5;
SELECT concat('myvar is ', myvar);

This prints myvar is 5 to stdout when the procedure runs.

Option 3, Create a table with one text column called tmptable, and push messages to it:

declare myvar INT default 0;
SET myvar = 5;
insert into tmptable select concat('myvar is ', myvar);

You could put the above in a stored procedure, so all you would have to write is this:

CALL log(concat('the value is', myvar));

Which saves a few keystrokes.

Option 4, Log messages to file

select "penguin" as log into outfile '/tmp/result.txt';

There is very heavy restrictions on this command. You can only write the outfile to areas on disk that give the 'others' group create and write permissions. It should work saving it out to /tmp directory.

Also once you write the outfile, you can't overwrite it. This is to prevent crackers from rooting your box just because they have SQL injected your website and can run arbitrary commands in MySQL.

try as below

@ContextConfiguration (locations = "classpath*:/spring/applicationContext*.xml")

this will load all 3 of your application context xml file.

Going forward, for graphical elements that are purely decorative, the best solution is to use:

android:importantForAccessibility="no"

This makes sense if your min SDK version is at least 16, since devices running lower versions will ignore this attribute.

If you're stuck supporting older versions, you should use (like others pointed out already):

android:contentDescription="@null"

Source: https://developer.android.com/guide/topics/ui/accessibility/apps#label-elements

Table setup:

CREATE TABLE dbo.tbl (
    action VARCHAR(20) NOT NULL,
    view_edit VARCHAR(20) NOT NULL
);

INSERT INTO dbo.tbl (action, view_edit)
VALUES ('Action1', 'VIEW'),
       ('Action1', 'EDIT'),
       ('Action2', 'VIEW'),
       ('Action3', 'VIEW'),
       ('Action3', 'EDIT');

Your table: SELECT action, view_edit FROM dbo.tbl

Query without using PIVOT:

SELECT Action, 
[View] = (Select view_edit FROM tbl WHERE t.action = action and view_edit = 'VIEW'),
[Edit] = (Select view_edit FROM tbl WHERE t.action = action and view_edit = 'EDIT')
FROM tbl t
GROUP BY Action

Query using PIVOT:

SELECT [Action], [View], [Edit] FROM
(SELECT [Action], view_edit FROM tbl) AS t1 
PIVOT (MAX(view_edit) FOR view_edit IN ([View], [Edit]) ) AS t2

Both queries result:

You can easily achieve what you want using the appendix package. Here's a sample file that shows you how. The key is the titletoc option when calling the package. It takes whatever value you've defined in \appendixname and the default value is Appendix.

\documentclass{report}
\usepackage[titletoc]{appendix}
\begin{document}
\tableofcontents

\chapter{Lorem ipsum}
\section{Dolor sit amet}
\begin{appendices}
  \chapter{Consectetur adipiscing elit}
  \chapter{Mauris euismod}
\end{appendices}
\end{document}

The output looks like

One advantage is for binding scenarios. Data grids and property grids will pick up the dynamic properties via the TypeDescriptor system. In addition, WPF data binding will understand dynamic properties, so WPF controls can bind to an ExpandoObject more readily than a dictionary.

Interoperability with dynamic languages, which will be expecting DLR properties rather than dictionary entries, may also be a consideration in some scenarios.

In my case setting the referenced object to NULL in my object before the merge o save method solve the problem, in my case the referenced object was catalog, that doesn't need to be saved, because in some cases I don't have it even.

    fisEntryEB.setCatStatesEB(null);

    (fisEntryEB) getSession().merge(fisEntryEB);

Escape it: someString.replace(/\//g, "-");

You can use:

try:
   # get your models
except ObjectDoesNotExist:
   # do something

With the java.time classes built into Java 8 and later:

public static void main(String[] args) {
        LocalDateTime localNow = LocalDateTime.now(TimeZone.getTimeZone("Europe/Madrid").toZoneId());
        System.out.println(localNow);
        // Prints current time of given zone without zone information : 2016-04-28T15:41:17.611
        ZonedDateTime zoneNow = ZonedDateTime.now(TimeZone.getTimeZone("Europe/Madrid").toZoneId());
        System.out.println(zoneNow);
        // Prints current time of given zone with zone information : 2016-04-28T15:41:17.627+02:00[Europe/Madrid]
    }

This is another clean solution:

sub, sup {vertical-align: baseline; position: relative; font-size: 70%;} /* 70% size of its parent element font-size which is good. */
sub {bottom: -0.6em;} /* use em becasue they adapt to parent font-size */
sup {top: -0.6em;} /* use em becasue they adapt to parent font-size */

In this way you can still use sup/sub tags but you fixed their idious behavior to always screw up paragraph line height.

So now you can do:

  <p>This is a line of text.</p>
  <p>This is a line of text, <sub>with sub text.</sub></p>
  <p>This is a line of text, <sup>with sup text.</sup></p>
  <p>This is a line of text.</p>

And your paragraph line height should not get screwed up.

Tested on IE7, IE8, FF3.6, SAFARI4, CHROME5, OPERA9

I tested using a p {line-height: 1.3;} (that is a good line height unless you want your lines to stick too close) and it still works, cause "-0.6em" is such a small amount that also with that line height the sub/sub text will fit and don't go over each other.

Forgot a detail that might be relevant I always use DOCTYPE in the 1st line of my page (specifically I use the HTML 4.01 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">). So I don't know if this solution works well when browser is in quirkmode (or not standard mode) due to lack of DOCTYPE or to a DOCTYPE that does not triggers Standard/Almost Standard mode.

ART

According to the docs: http://web.archive.org/web/20170909233829/https://source.android.com/devices/tech/dalvik/configure an .odex file:

contains AOT compiled code for methods in the APK.

Furthermore, they appear to be regular shared libraries, since if you get any app, and check:

file /data/app/com.android.appname-*/oat/arm64/base.odex

it says:

base.odex: ELF shared object, 64-bit LSB arm64, stripped

and aarch64-linux-gnu-objdump -d base.odex seems to work and give some meaningful disassembly (but also some rubbish sections).

This is occurring due to how PHP treats overloaded properties in that they are not modifiable or passed by reference.

See the manual for more information regarding overloading.

To work around this problem you can either use a __set function or create a createObject method.

Below is a __get and __set that provides a workaround to a similar situation to yours, you can simply modify the __set to suite your needs.

Note the __get never actually returns a variable. and rather once you have set a variable in your object it no longer is overloaded.

/**
 * Get a variable in the event.
 *
 * @param  mixed  $key  Variable name.
 *
 * @return  mixed|null
 */
public function __get($key)
{
    throw new \LogicException(sprintf(
        "Call to undefined event property %s",
        $key
    ));
}

/**
 * Set a variable in the event.
 *
 * @param  string  $key  Name of variable
 *
 * @param  mixed  $value  Value to variable
 *
 * @return  boolean  True
 */
public function __set($key, $value)
{
    if (stripos($key, '_') === 0 && isset($this->$key)) {
        throw new \LogicException(sprintf(
            "%s is a read-only event property", 
            $key
        ));
    }
    $this->$key = $value;
    return true;
}

Which will allow for:

$object = new obj();
$object->a = array();
$object->a[] = "b";
$object->v = new obj();
$object->v->a = "b";

This happened to me and I found a solution, see if this works for you:

Once you have built your project with the hammer icon:

1. select "Run".
2. Run Configurations.
3. Choose "C++ Application".
4. Click on the "New Launch Configuration" icon on the top left of the open window.
5. Select "Browse" under the C/C++ Application.
6. Browse to the folder where you made your project initially.
7. Enter the Debug folder.
8. Click on the binary file with the same name as the project.
9. Select "OK".
10. Click "Apply" to confirm the link you just set.
11. Close that window.

Afterwards you should be able to run the project as much as you'd like.

Hopefully this works for you.

dbms_output.put_line('Hi,');
dbms_output.put_line('good');
dbms_output.put_line('morning');
dbms_output.put_line('friends');

or

DBMS_OUTPUT.PUT_LINE('Hi, ' || CHR(13) || CHR(10) || 
                     'good' || CHR(13) || CHR(10) ||
                     'morning' || CHR(13) || CHR(10) ||
                     'friends' || CHR(13) || CHR(10) ||);

try it.

To further simplify B T's answer: Use refresh tokens when you don't typically want the user to have to type in credentials again, but still want the power to be able to revoke the permissions (by revoking the refresh token)

You cannot revoke an access token, only a refresh token.

In an upvoted comment to the accepted answer, Joe asks:

Is there any way to print to the console AND capture the output so that it shows in the junit report?

In UNIX, this is commonly referred to as teeing. Ideally, teeing rather than capturing would be the py.test default. Non-ideally, neither py.test nor any existing third-party py.test plugin (...that I know of, anyway) supports teeing – despite Python trivially supporting teeing out-of-the-box.

Monkey-patching py.test to do anything unsupported is non-trivial. Why? Because:

• Most py.test functionality is locked behind a private _pytest package not intended to be externally imported. Attempting to do so without knowing what you're doing typically results in the public pytest package raising obscure exceptions at runtime. ^{Thanks alot, py.test. Really robust architecture you got there.}
• Even when you do figure out how to monkey-patch the private _pytest API in a safe manner, you have to do so before running the public pytest package run by the external py.test command. You cannot do this in a plugin (e.g., a top-level conftest module in your test suite). By the time py.test lazily gets around to dynamically importing your plugin, any py.test class you wanted to monkey-patch has long since been instantiated – and you do not have access to that instance. This implies that, if you want your monkey-patch to be meaningfully applied, you can no longer safely run the external py.test command. Instead, you have to wrap the running of that command with a custom setuptools test command that (in order):
  1. Monkey-patches the private _pytest API.
  2. Calls the public pytest.main() function to run the py.test command.

This answer monkey-patches py.test's -s and --capture=no options to capture stderr but not stdout. By default, these options capture neither stderr nor stdout. This isn't quite teeing, of course. But every great journey begins with a tedious prequel everyone forgets in five years.

Why do this? I shall now tell you. My py.test-driven test suite contains slow functional tests. Displaying the stdout of these tests is helpful and reassuring, preventing leycec from reaching for killall -9 py.test when yet another long-running functional test fails to do anything for weeks on end. Displaying the stderr of these tests, however, prevents py.test from reporting exception tracebacks on test failures. Which is completely unhelpful. Hence, we coerce py.test to capture stderr but not stdout.

Before we get to it, this answer assumes you already have a custom setuptools test command invoking py.test. If you don't, see the Manual Integration subsection of py.test's well-written Good Practices page.

Do not install pytest-runner, a third-party setuptools plugin providing a custom setuptools test command also invoking py.test. If pytest-runner is already installed, you'll probably need to uninstall that pip3 package and then adopt the manual approach linked to above.

Assuming you followed the instructions in Manual Integration highlighted above, your codebase should now contain a PyTest.run_tests() method. Modify this method to resemble:

class PyTest(TestCommand):
             .
             .
             .
    def run_tests(self):
        # Import the public "pytest" package *BEFORE* the private "_pytest"
        # package. While importation order is typically ignorable, imports can
        # technically have side effects. Tragicomically, that is the case here.
        # Importing the public "pytest" package establishes runtime
        # configuration required by submodules of the private "_pytest" package.
        # The former *MUST* always be imported before the latter. Failing to do
        # so raises obtuse exceptions at runtime... which is bad.
        import pytest
        from _pytest.capture import CaptureManager, FDCapture, MultiCapture

        # If the private method to be monkey-patched no longer exists, py.test
        # is either broken or unsupported. In either case, raise an exception.
        if not hasattr(CaptureManager, '_getcapture'):
            from distutils.errors import DistutilsClassError
            raise DistutilsClassError(
                'Class "pytest.capture.CaptureManager" method _getcapture() '
                'not found. The current version of py.test is either '
                'broken (unlikely) or unsupported (likely).'
            )

        # Old method to be monkey-patched.
        _getcapture_old = CaptureManager._getcapture

        # New method applying this monkey-patch. Note the use of:
        #
        # * "out=False", *NOT* capturing stdout.
        # * "err=True", capturing stderr.
        def _getcapture_new(self, method):
            if method == "no":
                return MultiCapture(
                    out=False, err=True, in_=False, Capture=FDCapture)
            else:
                return _getcapture_old(self, method)

        # Replace the old with the new method.
        CaptureManager._getcapture = _getcapture_new

        # Run py.test with all passed arguments.
        errno = pytest.main(self.pytest_args)
        sys.exit(errno)

To enable this monkey-patch, run py.test as follows:

python setup.py test -a "-s"

Stderr but not stdout will now be captured. Nifty!

Extending the above monkey-patch to tee stdout and stderr is left as an exercise to the reader with a barrel-full of free time.

re.findall finds all the occurrence of the regex in a string and return in a list. Here, you are using a list of strings, you need this to use re.findall

Note - If the regex fails, an empty list is returned.

import re, sys

f = open('picklee', 'r')
lines = f.readlines()  
regex = re.compile(r'[A-Z]+')
for line in lines:
     print (re.findall(regex, line))

As you need access to your hostname variable in every component, and to change it to localhost while in development mode, or to production hostname when in production mode, you can define this variable in the prototype.

Like this:

Vue.prototype.$hostname = 'http://localhost:3000'

And $hostname will be available in all Vue instances:

new Vue({
  beforeCreate: function () {
    console.log(this.$hostname)
  }
})

In my case, to automatically change from development to production, I've defined the $hostname prototype according to a Vue production tip variable in the file where I instantiated the Vue.

Like this:

Vue.config.productionTip = false
Vue.prototype.$hostname = (Vue.config.productionTip) ? 'https://hostname' : 'http://localhost:3000'

An example can be found in the docs: Documentation on Adding Instance Properties

More about production tip config can be found here:

Vue documentation for production tip

I am sure there is a smarter way for doing what you want but this should work:

- name         : Test var
  hosts        : all
  gather_facts : no
  vars:
    myvariable : false
  tasks:
    - name: param1
      set_fact:
        myvariable: "{{param1}}"
      when: param1 is defined

    - name: param2
      set_fact:
        myvariable: "{{ param2 if not myvariable else myvariable + ',' + param2 }}"
      when: param2 is defined

    - name: param3
      set_fact:
        myvariable: "{{ param3 if not myvariable else myvariable + ',' + param3 }}"
      when: param3 is defined

    - name: default
      set_fact:
        myvariable: "default"
      when: not myvariable

    - debug:
       var=myvariable

Hope that helps. I am not sure if you can construct variables dynamically and do this in an iterator. But you could also write a small python code or any other language and plug it into ansible

Here is how you can do it :

public static void main(String[] args) {
    // TODO Auto-generated method stub
    int x = 3;
    int y = 2;
    Float fX = new Float(x);
    float res = fX.floatValue()/y;
    System.out.println("res = "+res);
}

See you !

Accessible to the classes in the same package only.

For example,

// Saved in file A.java
package pack;

class A{
  void msg(){System.out.println("Hello");}
}

// Saved in file B.java
package mypack;
import pack.*;

class B{
  public static void main(String args[]){
   A obj = new A(); // Compile Time Error
   obj.msg(); // Compile Time Error
  }
}

This access is more restricted than public and protected, but less restricted than private.

2. Public

Can be accessed from anywhere. (Global Access)

For example,

// Saved in file A.java

package pack;
public class A{
  public void msg(){System.out.println("Hello");}
}

// Saved in file B.java

package mypack;
import pack.*;

class B{
  public static void main(String args[]){
    A obj = new A();
    obj.msg();
  }
}

Output:Hello

3. Private

Accessible only inside the same class.

If you try to access private members on one class in another will throw compile error. For example,

class A{
  private int data = 40;
  private void msg(){System.out.println("Hello java");}
}

public class Simple{
  public static void main(String args[]){
    A obj = new A();
    System.out.println(obj.data); // Compile Time Error
    obj.msg(); // Compile Time Error
  }
}

4. Protected

Accessible only to the classes in the same package and to the subclasses

For example,

// Saved in file A.java
package pack;
public class A{
  protected void msg(){System.out.println("Hello");}
}

// Saved in file B.java
package mypack;
import pack.*;

class B extends A{
  public static void main(String args[]){
    B obj = new B();
    obj.msg();
  }
}

Output: Hello

There's no need for LINQ here, just call Sort:

list.Sort();

Example code:

List<int> list = new List<int> { 5, 7, 3 };
list.Sort();
foreach (int x in list)
{
    Console.WriteLine(x);
}

Result:

3
5
7

There have been many valid answers, however, none of them has the same syntax as tail in linux. The following function can be stored in your $Home\Documents\PowerShell\Microsoft.PowerShell_profile.ps1 for persistency (see powershell profiles documentation for more details).

This allows you to call...

tail server.log
tail -n 5 server.log
tail -f server.log
tail -Follow -Lines 5 -Path server.log

which comes quite close to the linux syntax.

function tail {
<#
    .SYNOPSIS
        Get the last n lines of a text file.
    .PARAMETER Follow
        output appended data as the file grows
    .PARAMETER Lines
        output the last N lines (default: 10)
    .PARAMETER Path
        path to the text file
    .INPUTS
        System.Int
        IO.FileInfo
    .OUTPUTS
        System.String
    .EXAMPLE
        PS> tail c:\server.log
    .EXAMPLE
        PS> tail -f -n 20 c:\server.log
#>
    [CmdletBinding()]
    [OutputType('System.String')]
    Param(
        [Alias("f")]
        [parameter(Mandatory=$false)]
        [switch]$Follow,

        [Alias("n")]
        [parameter(Mandatory=$false)]
        [Int]$Lines = 10,

        [parameter(Mandatory=$true, Position=5)]
        [ValidateNotNullOrEmpty()]
        [IO.FileInfo]$Path
    )
    if ($Follow)
    {
        Get-Content -Path $Path -Tail $Lines -Wait
    }
    else
    {
        Get-Content -Path $Path -Tail $Lines
    }
}

I've made this code in VB.NET but you can translate. Well pretend you have the variable Client as a TcpClient

Dim ClientRemoteIP As String = Client.Client.RemoteEndPoint.ToString.Remove(Client.Client.RemoteEndPoint.ToString.IndexOf(":"))

Hope it helps! Cheers.

You can use goto.

while ( ... ) {
   switch( ... ) {
     case ...:
         goto exit_loop;

   }
}
exit_loop: ;

SET NAMES UTF8

This is does the trick

Using Math.Round():

int percentComplete = (int)Math.Round((double)(100 * complete) / total);

or manually rounding:

int percentComplete = (int)(0.5f + ((100f * complete) / total));

You should wrap your elements inside a container, then use new CSS3 features like css grid, free course, and then use grid-gap:value that was created for your specific problem

span{_x000D_
  border:1px solid red;_x000D_
}_x000D_
.inRow{_x000D_
  display:grid;_x000D_
  grid-template-columns:repeat(auto-fill,auto);_x000D_
  grid-gap:10px /*This add space between elements, only works on grid items*/_x000D_
}_x000D_
.inColumn{_x000D_
  display:grid;_x000D_
  grid-template-rows:repeat(auto-fill,auto);_x000D_
  grid-gap:15px;_x000D_
}

<div class="inrow">_x000D_
  <span>1</span>_x000D_
  <span>2</span>_x000D_
  <span>3</span>_x000D_
</div>_x000D_
<div class="inColumn">_x000D_
  <span>4</span>_x000D_
  <span>5</span>_x000D_
  <span>6</span>_x000D_
</div>

Your issue is that your selector is for an anchor element <a>. You are treating the <a> tag as if it represents the page which is not the case.

$('head') will work as long as this selector is being executed by the page that needs the css.

Why not simply add the css file to the page in question. Any particular reason to attempt this dynamically from another page? I am not even familiar with a way to inject css to remote pages like this ... seems like it would be a major security hole.

ADDENDUM to your reasoning:

Then you should simply pass a parameter to the page, read it using javascript, and then do whatever is needed based on the parameter.

Move the session_start(); to top of the page always.

<?php
@ob_start();
session_start();
?>

Actually the enhanced for loop should look like this

for (final Room room : rooms) {
          // Here your room is available
}

Actually an other way to solve this could be, overwriting the CSS with insertRule.

It gives the ability to inject CSS rules to an existing/new stylesheet. In my concrete example it would look like this:

//creates a new `style` element in the document
var sheet = (function(){
  var style = document.createElement("style");
  // WebKit hack :(
  style.appendChild(document.createTextNode(""));
  // Add the <style> element to the page
  document.head.appendChild(style);
  return style.sheet;
})();

//add the actual rules to it
sheet.insertRule(
 "ul#mainFilter a:hover { color: #0000EE }" , 0
);

Demo with my 4 years old original example: http://jsfiddle.net/raPeX/21/

Use Windows Job Objects. Jobs are like process groups and can limit memory usage and process priority.

I had the same problem with JDK6,I changed the JDK to JDK8,the problem solved. Try to use JDK8!!!

If you are trying to do something similar to the Google search page when open in Chrome, (where certain events are triggered when you 'focus' on the page), then the hover() event may help.

$(window).hover(function() {
  // code here...
});

As others already mentioned, you can of course create via some tricks.

But it's not recommended.

Because the type erasure and more importantly the covariance in array which just allows a subtype array can be assigned to a supertype array, which forces you to use explicit type cast when trying to get the value back causing run-time ClassCastException which is one of the main objectives that generics try to eliminate: Stronger type checks at compile time.

Object[] stringArray = { "hi", "me" };
stringArray[1] = 1;
String aString = (String) stringArray[1]; // boom! the TypeCastException

A more direct example can found in Effective Java: Item 25.

covariance: an array of type S[] is a subtype of T[] if S is a subtype of T
