}

and return whatever orientations you want to support for each UIViewController

Anyway, I needed a way to catch the inherited Exception and that solution doesn't satisfy all my needs.

So I ended up changing how he handles OnException and this is my version

public override void OnException(HttpActionExecutedContext actionExecutedContext) {
   if (actionExecutedContext == null || actionExecutedContext.Exception == null) {
      return;
   }

   var type = actionExecutedContext.Exception.GetType();

   Tuple<HttpStatusCode?, Func<Exception, HttpRequestMessage, HttpResponseMessage>> registration = null;

   if (!this.Handlers.TryGetValue(type, out registration)) {
      //tento di vedere se ho registrato qualche eccezione che eredita dal tipo di eccezione sollevata (in ordine di registrazione)
      foreach (var item in this.Handlers.Keys) {
         if (type.IsSubclassOf(item)) {
            registration = this.Handlers[item];
            break;
         }
      }
   }

   //se ho trovato un tipo compatibile, uso la sua gestione
   if (registration != null) {
      var statusCode = registration.Item1;
      var handler = registration.Item2;

      var response = handler(
         actionExecutedContext.Exception.GetBaseException(),
         actionExecutedContext.Request
      );

      // Use registered status code if available
      if (statusCode.HasValue) {
         response.StatusCode = statusCode.Value;
      }

      actionExecutedContext.Response = response;
   }
   else {
      // If no exception handler registered for the exception type, fallback to default handler
      actionExecutedContext.Response = DefaultHandler(actionExecutedContext.Exception.GetBaseException(), actionExecutedContext.Request
      );
   }
}

The core is this loop where I check if the exception type is a subclass of a registered type.

foreach (var item in this.Handlers.Keys) {
    if (type.IsSubclassOf(item)) {
        registration = this.Handlers[item];
        break;
    }
}

COUNTIF function will only count cells that contain numbers in your specified range.

COUNTA(range) will count all values in the list of arguments. Text entries and numbers are counted, even when they contain an empty string of length 0.

Example: Function in A7 =COUNTA(A1:A6)

Range:

A1 a

A2 b

A3 banana

A4 42

A5

A6

A7 4 -> result

The example by user11617 is incorrect; it will report that the file exists even in cases where it does not, but there was an error of some other sort.

The signature should be Exists(string) (bool, error). And then, as it happens, the call sites are no better.

The code he wrote would better as:

func Exists(name string) bool {
    _, err := os.Stat(name)
    return !os.IsNotExist(err)
}

But I suggest this instead:

func Exists(name string) (bool, error) {
  _, err := os.Stat(name)
  if os.IsNotExist(err) {
    return false, nil
  }
  return err != nil, err
}

Both are valid but I normally choose interfaces. A class (abstract or not) is not needed if there is no implementations.

As an advise, try to choose the location of your constants wisely, they are part of your external contract. Do not put every single constant in one file.

For example, if a group of constants is only used in one class or one method put them in that class, the extended class or the implemented interfaces. If you do not take care you could end up with a big dependency mess.

Sometimes an enumeration is a good alternative to constants (Java 5), take look at: http://docs.oracle.com/javase/1.5.0/docs/guide/language/enums.html

POJO stands for Plain Old Java Object, and would be used to describe the same things as a "Normal Class" whereas a JavaBean follows a set of rules. Most commonly Beans use getters and setters to protect their member variables, which are typically set to private and have a no-argument public constructor. Wikipedia has a pretty good rundown of JavaBeans: http://en.wikipedia.org/wiki/JavaBeans

POJO is usually used to describe a class that doesn't need to be a subclass of anything, or implement specific interfaces, or follow a specific pattern.

The os.makedirs function does this. Try the following:

import os
import errno

filename = "/foo/bar/baz.txt"
if not os.path.exists(os.path.dirname(filename)):
    try:
        os.makedirs(os.path.dirname(filename))
    except OSError as exc: # Guard against race condition
        if exc.errno != errno.EEXIST:
            raise

with open(filename, "w") as f:
    f.write("FOOBAR")

The reason to add the try-except block is to handle the case when the directory was created between the os.path.exists and the os.makedirs calls, so that to protect us from race conditions.

In Python 3.2+, there is a more elegant way that avoids the race condition above:

import os

filename = "/foo/bar/baz.txt"
os.makedirs(os.path.dirname(filename), exist_ok=True)
with open(filename, "w") as f:
    f.write("FOOBAR")

Maven remembers when it didn't find something. The key is "resolution will not be reattempted until the update interval of internal has elapsed or updates are forced ->"

The quick solution is to delete your local "repository" subdirectory for the problem artifact - assuming you have fixed the problem with it. :)

mvn -U will force update from remote repository - again, assuming you have now populated remote with said artifact.

The easiest way is

find . -type  f -name '*.extension' 2>/dev/null | xargs grep -i string 

Edit: add 2>/dev/null to kill the error output

To include more file extensions and grep for password throughout the system:

find / -type  f \( -name '*.conf' -o -name "*.log" -o -name "*.bak" \) 2>/dev/null |
xargs grep -i password

TRY THIS

declare 
  a number;
begin
  a := :a;
dbms_output.put_line('Inputed Number is >> '|| a);
end;
/  

OR

declare 
  a number;
begin
  a := :x;
dbms_output.put_line('Inputed Number is >> '|| a);
end;
/

Just change the divider to an absolute number.i.e.

        A          B           C         D
1    25,000      50,000      75,000     200%

2   (25,000)     50,000      25,000     200%

The formula in D2 is: =(C2-A2)/ABS(A2) compare with the all positive row the result is the same (when the absolute base number is the same). Without the ABS in the formula the result will be -200%.

Note that as of Microsoft SQL Server 2016, UTF-8 is supported by bcp, BULK_INSERT, and OPENROWSET.

Addendum 2016-12-21: SQL Server 2016 SP1 now enables Unicode Compression (and most other previously Enterprise-only features) for all versions of MS SQL including Standard and Express. This is not the same as UTF-8 support, but it yields a similar benefit if the goal is disk space reduction for Western alphabets.

Or you can just create your own MediaTypeFormatter. I use this for text/html. If you add text/plain to it, it'll work for you too:

public class TextMediaTypeFormatter : MediaTypeFormatter
{
    public TextMediaTypeFormatter()
    {
        SupportedMediaTypes.Add(new MediaTypeHeaderValue("text/html"));
    }

    public override Task<object> ReadFromStreamAsync(Type type, Stream readStream, HttpContent content, IFormatterLogger formatterLogger)
    {
        return ReadFromStreamAsync(type, readStream, content, formatterLogger, CancellationToken.None);
    }

    public override async Task<object> ReadFromStreamAsync(Type type, Stream readStream, HttpContent content, IFormatterLogger formatterLogger, CancellationToken cancellationToken)
    {
        using (var streamReader = new StreamReader(readStream))
        {
            return await streamReader.ReadToEndAsync();
        }
    }

    public override bool CanReadType(Type type)
    {
        return type == typeof(string);
    }

    public override bool CanWriteType(Type type)
    {
        return false;
    }
}

Finally you have to assign this to the HttpMethodContext.ResponseFormatter property.

Once you read what What Every Computer Scientist Should Know About Floating-Point Arithmetic you could use the .toFixed() function:

var result = parseFloat('2.3') + parseFloat('2.4');
alert(result.toFixed(2));?

The best way is probably trying to open it, using just opendir() for instance.

Note that it's always best to try to use a filesystem resource, and handling any errors occuring because it doesn't exist, rather than just checking and then later trying. There is an obvious race condition in the latter approach.

Pass in the straight XML instead of a dictionary.

Here's a complete answer with Objective C and Swift:

1) Create an IBAction unwind segue in your destination view controller (where you want to segue to). Anywhere in the implementation file.

// Objective C

    - (IBAction)unwindToContainerVC:(UIStoryboardSegue *)segue {

    }

// Swift

 @IBAction func unwindToContainerVC(segue: UIStoryboardSegue) {

    }

2) On the source view controller (the controller you're segueing from), ^ + drag from "Name of activity" to exit. You should see the unwind segue created in step 1 in the popup. (If you don't see it, review step one). Pick unwindToContainerVC: from the popup, or whatever you named your method to connect your source controller to the unwind IBAction.

3) Select the segue in the source view controller's document outline of the storyboard (it will be listed near the bottom), and give it an identifier.

4) Call the unwind segue using this method from source view controller, substituting your unwind segue name.

// Objective C

[self performSegueWithIdentifier:@"unwindToContainerVC" sender:self];

// Swift

self.performSegueWithIdentifier("unwindToContainerVC", sender: self)

NB. Use the sourceViewController property of the segue parameter on the unwind method to access any exposed properties on the source controller. Also, notice that the framework handles dismissing the source controller. If you'd like to confirm this add a dealloc method to the source controller with a log message that should fire once it has been killed. If dealloc doesn't fire you may have a retain cycle.

Prefix URL changes with a hashtag to avoid a redirect.

This redirects

location.href += '&test='true';

This doesn't redirect

location.href += '#&test='true';

I would have to agree with you. There are a lot of possibilities in django but best place to start is reviewing Django's design philosophy.

1. Calling an API from a model property would not be ideal, it seems like it would make more sense to do something like this in the view and possibly create a service layer to keep things dry. If the call to the API is non-blocking and the call is an expensive one, sending the request to a service worker (a worker that consumes from a queue) might make sense.

2. As per Django's design philosophy models encapsulate every aspect of an "object". So all business logic related to that object should live there:

Include all relevant domain logic

Models should encapsulate every aspect of an “object,” following Martin Fowler’s Active Record design pattern.

3. The side effects you describe are apparent, the logic here could be better broken down into Querysets and managers. Here is an example:

   models.py

   import datetime
   
   from djongo import models
   from django.db.models.query import QuerySet
   from django.contrib import admin
   from django.db import transaction
   
   
   class MyUser(models.Model):
   
       present_name = models.TextField(null=False, blank=True)
       status = models.TextField(null=False, blank=True)
       last_active = models.DateTimeField(auto_now=True, editable=False)
   
       # As mentioned you could put this in a template tag to pull it
       # from cache there. Depending on how it is used, it could be
       # retrieved from within the admin view or from a custom view
       # if that is the only place you will use it.
       #def get_present_name(self):
       #    # property became non-deterministic in terms of database
       #    # data is taken from another service by api
       #    return remote_api.request_user_name(self.uid) or 'Anonymous'
   
       # Moved to admin as an action
       # def activate(self):
       #     # method now has a side effect (send message to user)
       #     self.status = 'activated'
       #     self.save()
       #     # send email via email service
       #     #send_mail('Your account is activated!', '…', [self.email])
   
       class Meta:
           ordering = ['-id']  # Needed for DRF pagination
   
       def __unicode__(self):
           return '{}'.format(self.pk)
   
   
   class MyUserRegistrationQuerySet(QuerySet):
   
       def for_inactive_users(self):
           new_date = datetime.datetime.now() - datetime.timedelta(days=3*365)  # 3 Years ago
           return self.filter(last_active__lte=new_date.year)
   
       def by_user_id(self, user_ids):
           return self.filter(id__in=user_ids)
   
   
   class MyUserRegistrationManager(models.Manager):
   
       def get_query_set(self):
           return MyUserRegistrationQuerySet(self.model, using=self._db)
   
       def with_no_activity(self):
           return self.get_query_set().for_inactive_users()
   

   admin.py

   # Then in model admin
   
   class MyUserRegistrationAdmin(admin.ModelAdmin):
       actions = (
           'send_welcome_emails',
       )
   
       def send_activate_emails(self, request, queryset):
           rows_affected = 0
           for obj in queryset:
               with transaction.commit_on_success():
                   # send_email('welcome_email', request, obj) # send email via email service
                   obj.status = 'activated'
                   obj.save()
                   rows_affected += 1
   
           self.message_user(request, 'sent %d' % rows_affected)
   
   admin.site.register(MyUser, MyUserRegistrationAdmin)
   

Below i describe my method. I set event on input in input, to call Masking() method, which will return an formatted string of that we insert in input.

Html:

<input name="phone" pattern="+373 __ ___ ___" class="masked" required>

JQ: Here we set event on input:

$('.masked').on('input', function () {
    var input = $(this);
    input.val(Masking(input.val(), input.attr('pattern')));
});

JS: Function, which will format string by pattern;

function Masking (value, pattern) {
var out = '';
var space = ' ';
var any = '_';

for (var i = 0, j = 0; j < value.length; i++, j++) {
    if (value[j] === pattern[i]) {
        out += value[j];
    }
    else if(pattern[i] === any && value[j] !== space) {
        out += value[j];
    }
    else if(pattern[i] === space && value[j] !== space) {
        out += space;
        j--;
    }
    else if(pattern[i] !== any && pattern[i] !== space) {
        out += pattern[i];
        j--;
    }
}

return out;

An update for Windows 10 Ubuntu Application via Subsystem (also works on standard Ubuntu):

You might have problems finding the package. If you do, never fear! PPA is here!

sudo add-apt-repository ppa:boost-latest/ppa
sudo apt-get update

Then run:

sudo apt-get install libboost-all-dev

You can always use the good old observer pattern if you want to avoid the tyranny and overhead of $watch.

In the service:

factory('aService', function() {
  var observerCallbacks = [];

  //register an observer
  this.registerObserverCallback = function(callback){
    observerCallbacks.push(callback);
  };

  //call this when you know 'foo' has been changed
  var notifyObservers = function(){
    angular.forEach(observerCallbacks, function(callback){
      callback();
    });
  };

  //example of when you may want to notify observers
  this.foo = someNgResource.query().$then(function(){
    notifyObservers();
  });
});

And in the controller:

function FooCtrl($scope, aService){
  var updateFoo = function(){
    $scope.foo = aService.foo;
  };

  aService.registerObserverCallback(updateFoo);
  //service now in control of updating foo
};

In earlier versions of Chrome we could simply select and copy an element (with Ctrl+C or Cmd+C) and then paste it inside an element by selecting it and then paste (with Ctrl+V or Cmd+V). It's not possible in the latest versions though (I'm running Chrome 58.0.3029.110) and it has set me up many times since then.

Instead of using the commands for copy and paste, we now have to right click the element -> Copy -> Copy Element and then right click the element that we want to append the copied element to -> Copy -> Paste Element.

I don't understand why the short commands are deactivated but at least it's still possible to do it in a more inconvenient way.

If you are reading this and you are using Spring Boot, you have 1 more option for this feature

Usually comma separated list are very clumsy for real world use case (And sometime not even feasible, if you want to use commas in your config):

[email protected],[email protected],[email protected],.....

With Spring Boot, you can write it like these (Index start at 0):

email.sendTo[0][email protected]
email.sendTo[1][email protected]
email.sendTo[2][email protected]

And use it like these:

@Component
@ConfigurationProperties("email")
public class EmailProperties {

    private List<String> sendTo;

    public List<String> getSendTo() {
        return sendTo;
    }

    public void setSendTo(List<String> sendTo) {
        this.sendTo = sendTo;
    }

}


@Component
public class EmailModel {

  @Autowired
  private EmailProperties emailProperties;

  //Use the sendTo List by 
  //emailProperties.getSendTo()

}



@Configuration
public class YourConfiguration {
    @Bean
  public EmailProperties emailProperties(){
        return new EmailProperties();
  }

}


#Put this in src/main/resource/META-INF/spring.factories
  org.springframework.boot.autoconfigure.EnableAutoConfiguration=example.compackage.YourConfiguration

I found this code where date is compared in a format to compare with date field in database...may be this might be helpful to you...

When you convert the string to date using simpledateformat, it is hard to compare with the Date field in mysql databases.

So convert the java string date in the format using select STR_to_DATE('yourdate','%m/%d/%Y') --> in this format, then you will get the exact date format of mysql date field.

http://javainfinite.com/java/java-convert-string-to-date-and-compare/

convert a 1-dimensional array into a 2-dimensional array by adding new axis.

a=np.array([10,20,30,40,50,60])

b=a[:,np.newaxis]--it will convert it to two dimension.

in your Oncreate():

`

myTask.execute("url");
String result = "";
try {
      result = myTask.get().toString();
} catch (InterruptedException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
}catch (ExecutionException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();

}`

I figured out that in my case, my database was in different subnet than the subnet from where i was trying to access the db.

Try this:

$mpdf->Output('my_filename.pdf','D'); 

because:

D - means Download
F - means File-save only

I just solved this exact issue for myself; even referenced this question.

I'm assuming you haven't written the "all" rule that Eclipse is complaining about. If this is the case, take these steps:

1. Go to Project Properties > C/C++ Build > Behaviour Tab.
2. Leave Build (Incremental Build) Checked.
3. Remove "all" from the text box next to Build (Incremental Build).
4. Compile away!

This lets Eclipse know you aren't trying to use a make target called "all". For some reason, that is the default.

Declared but did not define a variable or function.

A typical variable declaration is

extern int x;

As this is only a declaration, a single definition is needed. A corresponding definition would be:

int x;

For example, the following would generate an error:

extern int x;
int main()
{
    x = 0;
}
//int x; // uncomment this line for successful definition

Similar remarks apply to functions. Declaring a function without defining it leads to the error:

void foo(); // declaration only
int main()
{
   foo();
}
//void foo() {} //uncomment this line for successful definition

Be careful that the function you implement exactly matches the one you declared. For example, you may have mismatched cv-qualifiers:

void foo(int& x);
int main()
{
   int x;
   foo(x);
}
void foo(const int& x) {} //different function, doesn't provide a definition
                          //for void foo(int& x)
                          

Other examples of mismatches include

• Function/variable declared in one namespace, defined in another.
• Function/variable declared as class member, defined as global (or vice versa).
• Function return type, parameter number and types, and calling convention do not all exactly agree.

The error message from the compiler will often give you the full declaration of the variable or function that was declared but never defined. Compare it closely to the definition you provided. Make sure every detail matches.

It's an old question but i faced a very same scenario, i need to split a string using as demiliter the word "low" the problem for me was that i have in the same string the word below and lower.

I solved it using the re module this way

import re

string = '...below...as higher prices mean lower demand to be expected. Generally, a high reading is seen as negative (or bearish), while a low reading is seen as positive (or bullish) for the Korean Won.'

use re.split with regex to match the exact word

stringafterword = re.split('\\blow\\b',string)[-1]
print(stringafterword)
' reading is seen as positive (or bullish) for the Korean Won.'

the generic code is:

re.split('\\bTHE_WORD_YOU_WANT\\b',string)[-1]

Hope this can help someone!

i did this:

$("#myModal").modal({}).draggable();

and it make my very standard/basic modal draggable.

not sure how/why it worked, but it did.

You can display an image in your own window using Tkinter, w/o depending on image viewers installed in your system:

import Tkinter as tk
from PIL import Image, ImageTk  # Place this at the end (to avoid any conflicts/errors)

window = tk.Tk()
#window.geometry("500x500") # (optional)    
imagefile = {path_to_your_image_file}
img = ImageTk.PhotoImage(Image.open(imagefile))
lbl = tk.Label(window, image = img).pack()
window.mainloop()

For Python 3, replace import Tkinter as tk with import tkinter as tk.

As far as I know there is not an easy way to do this since Javascript/JQuery does not have access to the local filesystem. There are some new features in html 5 that allows you to check certain meta data such as file size but I'm not sure if you can actually get the image dimensions.

Here is an article I found regarding the html 5 features, and a work around for IE that involves using an ActiveX control. http://jquerybyexample.blogspot.com/2012/03/how-to-check-file-size-before-uploading.html

(Can't comment yet with enough reputation , let me add a sidenote)

Just in case your output need to be fixed length of 3-digit , i.e. for number run up to 1000 or more (reserved fixed length), don't forget to add mod 1000 on it .

yourNumber=1001;
yourString= yourNumber.ToString("D3");        // "1001" 
yourString= (yourNumber%1000).ToString("D3"); // "001" truncated to 3-digit as expected

Use the builtin type function to get the type, then you can use the __module__ property to find out where it was defined:

>>> import numpy as np
a = np.array([1, 2, 3])
>>> type(a)
<type 'numpy.ndarray'>
>>> type(a).__module__
'numpy'
>>> type(a).__module__ == np.__name__
True

This will work:

DECLARE @MS INT = 235216
select cast(dateadd(ms, @MS, '00:00:00') AS TIME(3))

(where ms is just a number of seconds not a timeformat)

Try:

throw new Exception("transction: " + transNbr, E); 

The next approach work to me with Visual Studio 2013 Update 4 1- From Solution Explorer right click on References then select add references 2- Assemblies > Framework > System.Data.OracleClient > OK and after that you free to add using System.Data.OracleClient in your application and deal with database like you do with Sql Server database except changing the prefix from Sql to Oracle as in SqlCommand become OracleCommand for example to link to Oracle XE

OracleConnection oraConnection = new OracleConnection(@"Data Source=XE; User ID=system; Password=*myPass*");
public void Open()
{
if (oraConnection.State != ConnectionState.Open)
{
oraConnection.Open();
}
}
public void Close()
{
if (oraConnection.State == ConnectionState.Open)
{
oraConnection.Close();
}}

and to execute some command like INSERT, UPDATE, or DELETE using stored procedure we can use the following method

public void ExecuteCMD(string storedProcedure, OracleParameter[] param)
{
OracleCommand oraCmd = new OracleCommand();
oraCmd,CommandType = CommandType.StoredProcedure;
oraCmd.CommandText = storedProcedure;
oraCmd.Connection = oraConnection;

if(param!=null)
{
oraCmd.Parameters.AddRange(param);
}
try
{
oraCmd.ExecuteNoneQuery();
}
catch (Exception)
{
MessageBox.Show("Sorry We've got Unknown Error","Connection Error",MessageBoxButtons.OK,MessageBoxIcon.Error);
}
}

A quick and easy solution for those who don't have much deviation from default VS settings.

Tools-->Import and Export Settings-->Yes, save my current settings-->Visual C#

I am sure the above solution would work with other default settings too. In my case something messed up with my symbol loading settings but I could not fix it even though I tried quite a few of the suggested solutions.

In the first instance you are trying to create what is called a jagged array.

double[][] ServicePoint = new double[10][9].

The above statement would have worked if it was defined like below.

double[][] ServicePoint = new double[10][]

what this means is you are creating an array of size 10 ,that can store 10 differently sized arrays inside it.In simple terms an Array of arrays.see the below image,which signifies a jagged array.

http://msdn.microsoft.com/en-us/library/2s05feca(v=vs.80).aspx

The second one is basically a two dimensional array and the syntax is correct and acceptable.

  double[,] ServicePoint = new double[10,9];//<-ok (2)

And to access or modify a two dimensional array you have to pass both the dimensions,but in your case you are passing just a single dimension,thats why the error

Correct usage would be

ServicePoint[0][2] ,Refers to an item on the first row ,third column.

Pictorial rep of your two dimensional array

No, there is no built in conversion for this. You'll need to create a constructor, like you mentioned, or some other conversion method.

Also, since BaseClass is not a DerivedClass, myDerivedObject will be null, andd the last line above will throw a null ref exception.

Here's a straightforward way to do this:

First, create a history table for each data table you want to track (example query below). This table will have an entry for each insert, update, and delete query performed on each row in the data table.

The structure of the history table will be the same as the data table it tracks except for three additional columns: a column to store the operation that occured (let's call it 'action'), the date and time of the operation, and a column to store a sequence number ('revision'), which increments per operation and is grouped by the primary key column of the data table.

To do this sequencing behavior a two column (composite) index is created on the primary key column and revision column. Note that you can only do sequencing in this fashion if the engine used by the history table is MyISAM (See 'MyISAM Notes' on this page)

The history table is fairly easy to create. In the ALTER TABLE query below (and in the trigger queries below that), replace 'primary_key_column' with the actual name of that column in your data table.

CREATE TABLE MyDB.data_history LIKE MyDB.data;

ALTER TABLE MyDB.data_history MODIFY COLUMN primary_key_column int(11) NOT NULL, 
   DROP PRIMARY KEY, ENGINE = MyISAM, ADD action VARCHAR(8) DEFAULT 'insert' FIRST, 
   ADD revision INT(6) NOT NULL AUTO_INCREMENT AFTER action,
   ADD dt_datetime DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP AFTER revision,
   ADD PRIMARY KEY (primary_key_column, revision);

And then you create the triggers:

DROP TRIGGER IF EXISTS MyDB.data__ai;
DROP TRIGGER IF EXISTS MyDB.data__au;
DROP TRIGGER IF EXISTS MyDB.data__bd;

CREATE TRIGGER MyDB.data__ai AFTER INSERT ON MyDB.data FOR EACH ROW
    INSERT INTO MyDB.data_history SELECT 'insert', NULL, NOW(), d.* 
    FROM MyDB.data AS d WHERE d.primary_key_column = NEW.primary_key_column;

CREATE TRIGGER MyDB.data__au AFTER UPDATE ON MyDB.data FOR EACH ROW
    INSERT INTO MyDB.data_history SELECT 'update', NULL, NOW(), d.*
    FROM MyDB.data AS d WHERE d.primary_key_column = NEW.primary_key_column;

CREATE TRIGGER MyDB.data__bd BEFORE DELETE ON MyDB.data FOR EACH ROW
    INSERT INTO MyDB.data_history SELECT 'delete', NULL, NOW(), d.* 
    FROM MyDB.data AS d WHERE d.primary_key_column = OLD.primary_key_column;

And you're done. Now, all the inserts, updates and deletes in 'MyDb.data' will be recorded in 'MyDb.data_history', giving you a history table like this (minus the contrived 'data_columns' column)

ID    revision   action    data columns..
1     1         'insert'   ....          initial entry for row where ID = 1
1     2         'update'   ....          changes made to row where ID = 1
2     1         'insert'   ....          initial entry, ID = 2
3     1         'insert'   ....          initial entry, ID = 3 
1     3         'update'   ....          more changes made to row where ID = 1
3     2         'update'   ....          changes made to row where ID = 3
2     2         'delete'   ....          deletion of row where ID = 2 

To display the changes for a given column or columns from update to update, you'll need to join the history table to itself on the primary key and sequence columns. You could create a view for this purpose, for example:

CREATE VIEW data_history_changes AS 
   SELECT t2.dt_datetime, t2.action, t1.primary_key_column as 'row id', 
   IF(t1.a_column = t2.a_column, t1.a_column, CONCAT(t1.a_column, " to ", t2.a_column)) as a_column
   FROM MyDB.data_history as t1 INNER join MyDB.data_history as t2 on t1.primary_key_column = t2.primary_key_column 
   WHERE (t1.revision = 1 AND t2.revision = 1) OR t2.revision = t1.revision+1
   ORDER BY t1.primary_key_column ASC, t2.revision ASC

Edit: Oh wow, people like my history table thing from 6 years ago :P

My implementation of it is still humming along, getting bigger and more unwieldy, I would assume. I wrote views and pretty nice UI to look at the history in this database, but I don't think it was ever used much. So it goes.

To address some comments in no particular order:

• I did my own implementation in PHP that was a little more involved, and avoided some of the problems described in comments (having indexes transferred over, signifcantly. If you transfer over unique indexes to the history table, things will break. There are solutions for this in the comments). Following this post to the letter could be an adventure, depending on how established your database is.

• If the relationship between the primary key and the revision column seems off it usually means the composite key is borked somehow. On a few rare occasions I had this happen and was at a loss to the cause.

• I found this solution to be pretty performant, using triggers as it does. Also, MyISAM is fast at inserts, which is all the triggers do. You can improve this further with smart indexing (or lack of...). Inserting a single row into a MyISAM table with a primary key shouldn't be an operation you need to optimize, really, unless you have significant issues going on elsewhere. In the entire time I was running the MySQL database this history table implementation was on, it was never the cause of any of the (many) performance problems that came up.

• if you're getting repeated inserts, check your software layer for INSERT IGNORE type queries. Hrmm, can't remember now, but I think there are issues with this scheme and transactions which ultimately fail after running multiple DML actions. Something to be aware of, at least.

• It's important that the fields in the history table and the data table match up. Or, rather, that your data table doesn't have MORE columns than the history table. Otherwise, insert/update/del queries on the data table will fail, when the inserts to the history tables put columns in the query that don't exist (due to d.* in the trigger queries), and the trigger fails. t would be awesome if MySQL had something like schema-triggers, where you could alter the history table if columns were added to the data table. Does MySQL have that now? I do React these days :P

I have also used following link as others have suggested you for bluetooth communication.

http://developer.android.com/guide/topics/connectivity/bluetooth.html

The thing is all you need is a class BluetoothChatService.java

this class has following threads:

1. Accept
2. Connecting
3. Connected

Now when you call start function of the BluetoothChatService like:

mChatService.start();

It starts accept thread which means it will start looking for connection.

Now when you call

mChatService.connect(<deviceObject>,false/true);

Here first argument is device object that you can get from paired devices list or when you scan for devices you will get all the devices in range you can pass that object to this function and 2nd argument is a boolean to make secure or insecure connection.

connect function will start connecting thread which will look for any device which is running accept thread.

When such a device is found both accept thread and connecting thread will call connected function in BluetoothChatService:

connected(mmSocket, mmDevice, mSocketType);

this method starts connected thread in both the devices: Using this socket object connected thread obtains the input and output stream to the other device. And calls read function on inputstream in a while loop so that it's always trying read from other device so that whenever other device send a message this read function returns that message.

BluetoothChatService also has a write method which takes byte[] as input and calls write method on connected thread.

mChatService.write("your message".getByte());

write method in connected thread just write this byte data to outputsream of the other device.

public void write(byte[] buffer) {
   try {
       mmOutStream.write(buffer);
    // Share the sent message back to the UI Activity
    // mHandler.obtainMessage(
    // BluetoothGameSetupActivity.MESSAGE_WRITE, -1, -1,
    // buffer).sendToTarget();
    } catch (IOException e) {
    Log.e(TAG, "Exception during write", e);
     }
}

Now to communicate between two devices just call write function on mChatService and handle the message that you will receive on the other device.

In a Nutshell

An unwind segue (sometimes called exit segue) can be used to navigate back through push, modal or popover segues (as if you popped the navigation item from the navigation bar, closed the popover or dismissed the modally presented view controller). On top of that you can actually unwind through not only one but a series of push/modal/popover segues, e.g. "go back" multiple steps in your navigation hierarchy with a single unwind action.

When you perform an unwind segue, you need to specify an action, which is an action method of the view controller you want to unwind to.

Objective-C:

- (IBAction)unwindToThisViewController:(UIStoryboardSegue *)unwindSegue
{
}

Swift:

@IBAction func unwindToThisViewController(segue: UIStoryboardSegue) {
}

The name of this action method is used when you create the unwind segue in the storyboard. Furthermore, this method is called just before the unwind segue is performed. You can get the source view controller from the passed UIStoryboardSegue parameter to interact with the view controller that initiated the segue (e.g. to get the property values of a modal view controller). In this respect, the method has a similar function as the prepareForSegue: method of UIViewController.

iOS 8 update: Unwind segues also work with iOS 8's adaptive segues, such as Show and Show Detail.

An Example

Let us have a storyboard with a navigation controller and three child view controllers:

From Green View Controller you can unwind (navigate back) to Red View Controller. From Blue you can unwind to Green or to Red via Green. To enable unwinding you must add the special action methods to Red and Green, e.g. here is the action method in Red:

Objective-C:

@implementation RedViewController

- (IBAction)unwindToRed:(UIStoryboardSegue *)unwindSegue
{
}

@end

Swift:

@IBAction func unwindToRed(segue: UIStoryboardSegue) {
}

After the action method has been added, you can define the unwind segue in the storyboard by control-dragging to the Exit icon. Here we want to unwind to Red from Green when the button is pressed:

You must select the action which is defined in the view controller you want to unwind to:

You can also unwind to Red from Blue (which is "two steps away" in the navigation stack). The key is selecting the correct unwind action.

Before the the unwind segue is performed, the action method is called. In the example I defined an unwind segue to Red from both Green and Blue. We can access the source of the unwind in the action method via the UIStoryboardSegue parameter:

Objective-C:

- (IBAction)unwindToRed:(UIStoryboardSegue *)unwindSegue
{
    UIViewController* sourceViewController = unwindSegue.sourceViewController;

    if ([sourceViewController isKindOfClass:[BlueViewController class]])
    {
        NSLog(@"Coming from BLUE!");
    }
    else if ([sourceViewController isKindOfClass:[GreenViewController class]])
    {
        NSLog(@"Coming from GREEN!");
    }
}

Swift:

@IBAction func unwindToRed(unwindSegue: UIStoryboardSegue) {
    if let blueViewController = unwindSegue.sourceViewController as? BlueViewController {
        println("Coming from BLUE")
    }
    else if let redViewController = unwindSegue.sourceViewController as? RedViewController {
        println("Coming from RED")
    }
}

Unwinding also works through a combination of push/modal segues. E.g. if I added another Yellow view controller with a modal segue, we could unwind from Yellow all the way back to Red in a single step:

Unwinding from Code

When you define an unwind segue by control-dragging something to the Exit symbol of a view controller, a new segue appears in the Document Outline:

Selecting the segue and going to the Attributes Inspector reveals the "Identifier" property. Use this to give a unique identifier to your segue:

After this, the unwind segue can be performed from code just like any other segue:

Objective-C:

[self performSegueWithIdentifier:@"UnwindToRedSegueID" sender:self];

Swift:

performSegueWithIdentifier("UnwindToRedSegueID", sender: self)

Another easy way is to use the WC_Product_Factory class and then call function get_product(ID)

http://docs.woothemes.com/wc-apidocs/source-class-WC_Product_Factory.html#16-63

sample:

// assuming the list of product IDs is are stored in an array called IDs;
$_pf = new WC_Product_Factory();  
foreach ($IDs as $id) {

    $_product = $_pf->get_product($id);

    // from here $_product will be a fully functional WC Product object, 
    // you can use all functions as listed in their api
}

You can then use all the function calls as listed in their api: http://docs.woothemes.com/wc-apidocs/class-WC_Product.html

Try this to switch to php4:

AddHandler application/x-httpd-php4 .php

Upd. Looks like I didn't understand your question correctly. This will not help if you have only php 4 on your server.

Install ODAC 64 bit driver using CMD after install ODAC 32 bit:

1. Go to ODAC bit folder where install.bat file is located using CMD.

2. Type install.bat all c:/oracle odac command and press Enter.

   Installation file will be located at “c:/oracle” folder.

When installing Oracle 11g client 32 and 64 bit, you must change oracle base path: “c:/oracle”

string uriPath =
    "file:\\C:\\Users\\john\\documents\\visual studio 2010\\Projects\\proj";
string localPath = new Uri(uriPath).LocalPath;

Don't write if statements without a corresponding else. Once you add the else to your fragment you'll see that your true and false are in fact the last expressions of the function.

What you can do to resolve your conflict is

svn resolve --accept working -R <path>

where <path> is where you have your conflict (can be the root of your repo).

Explanations:

• resolve asks svn to resolve the conflict
• accept working specifies to keep your working files
• -R stands for recursive

Hope this helps.

EDIT:

To sum up what was said in the comments below:

• <path> should be the directory in conflict (C:\DevBranch\ in the case of the OP)
• it's likely that the origin of the conflict is
  • either the use of the svn switch command
  • or having checked the Switch working copy to new branch/tag option at branch creation
• more information about conflicts can be found in the dedicated section of Tortoise's documentation.
• to be able to run the command, you should have the CLI tools installed together with Tortoise:

Here's pure javascript example of handling classes during scrolling.

You'd probably want to throttle handling scroll events, more so as handler logic gets more complex, in that case throttle from lodash lib comes in handy.

And if you're doing spa, keep in mind that you need to clear event listeners with removeEventListener once they're not needed (eg during onDestroy lifecycle hook of your component, like destroyed() for Vue, or maybe return function of useEffect hook for React).

const navbar = document.getElementById('navbar')_x000D_
_x000D_
// OnScroll event handler_x000D_
const onScroll = () => {_x000D_
_x000D_
  // Get scroll value_x000D_
  const scroll = document.documentElement.scrollTop_x000D_
_x000D_
  // If scroll value is more than 0 - add class_x000D_
  if (scroll > 0) {_x000D_
    navbar.classList.add("scrolled");_x000D_
  } else {_x000D_
    navbar.classList.remove("scrolled")_x000D_
  }_x000D_
}_x000D_
_x000D_
// Optional - throttling onScroll handler at 100ms with lodash_x000D_
const throttledOnScroll = _.throttle(onScroll, 100, {})_x000D_
_x000D_
// Use either onScroll or throttledOnScroll_x000D_
window.addEventListener('scroll', onScroll)

#navbar {_x000D_
  position: fixed;_x000D_
  top: 0;_x000D_
  left: 0;_x000D_
  right: 0;_x000D_
  width: 100%;_x000D_
  height: 60px;_x000D_
  background-color: #89d0f7;_x000D_
  box-shadow: 0px 5px 0px rgba(0, 0, 0, 0);_x000D_
  transition: box-shadow 500ms;_x000D_
}_x000D_
_x000D_
#navbar.scrolled {_x000D_
  box-shadow: 0px 5px 10px rgba(0, 0, 0, 0.25);_x000D_
}_x000D_
_x000D_
#content {_x000D_
  height: 3000px;_x000D_
  margin-top: 60px;_x000D_
}

<!-- Optional - lodash library, used for throttlin onScroll handler-->_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.15/lodash.js"></script>_x000D_
<header id="navbar"></header>_x000D_
<div id="content"></div>

This can work:

int no=0;
try
{
    no=Integer.parseInt(string);
    if(string.contains("."))
    {
        if(string.contains("f"))
        {
            System.out.println("float");
        }
        else
            System.out.println("double");
    }
}

catch(Exception ex)
{
    Console.WriteLine("not numeric or string");
}

In practice, it is possible, if you use span element instead of font:

<style>
u { color: black; }
.red { color: red }
</style>
<u><span class='red'><br>$username</span></u>

See jsfiddle. Appears to work on Chrome, Safari, Firefox, IE, Opera (tested on Win 7 with newest versions).

The code in the question should work, too, but it does not work for some reason on WebKit browsers (Chrome, Safari).

By the CSS spec: “The color(s) required for the text decoration must be derived from the 'color' property value of the element on which 'text-decoration' is set. The color of decorations must remain the same even if descendant elements have different 'color' values.”

You can think of the modulus operator as giving you a remainder. count % 6 divides 6 out of count as many times as it can and gives you a remainder from 0 to 5 (These are all the possible remainders because you already divided out 6 as many times as you can). The elements of the array are all printed in the for loop, but every time the remainder is 5 (every 6th element), it outputs a newline character. This gives you 6 elements per line. For 5 elements per line, use

if (count % 5 == 4)

Use numpy.

import numpy as np
b = list(np.array(a)**2)

I was looking for a general way of adding a column of numpy.nans to a dataframe without getting the dumb SettingWithCopyWarning.

From the following:

• the answers here
• this question about passing a variable as a keyword argument
• this method for generating a numpy array of NaNs in-line

I came up with this:

col = 'column_name'
df = df.assign(**{col:numpy.full(len(df), numpy.nan)})

Based on L.B.'s answer.

Usage:

var serializer = new DictionarySerializer<string, string>();
serializer.Serialize("dictionary.xml", _dictionary);
_dictionary = _titleDictSerializer.Deserialize("dictionary.xml");

Generic class:

public class DictionarySerializer<TKey, TValue>
{
    [XmlType(TypeName = "Item")]
    public class Item
    {
        [XmlAttribute("key")]
        public TKey Key;
        [XmlAttribute("value")]
        public TValue Value;
    }

    private XmlSerializer _serializer = new XmlSerializer(typeof(Item[]), new XmlRootAttribute("Dictionary"));

    public Dictionary<TKey, TValue> Deserialize(string filename)
    {
        using (FileStream stream = new FileStream(filename, FileMode.Open))
        using (XmlReader reader = XmlReader.Create(stream))
        {
            return ((Item[])_serializer.Deserialize(reader)).ToDictionary(p => p.Key, p => p.Value);
        }
    }

    public void Serialize(string filename, Dictionary<TKey, TValue> dictionary)
    {
        using (var writer = new StreamWriter(filename))
        {
            _serializer.Serialize(writer, dictionary.Select(p => new Item() { Key = p.Key, Value = p.Value }).ToArray());
        }
    }
}

You can simply put javascript expression in ng-model.

If you look in your installation's bin directory you will see catalina.sh or .bat scripts. If you look in these you will see that they run a setenv.sh or setenv.bat script respectively, if it exists, to set environment variables. The relevant environment variables are described in the comments at the top of catalina.sh/bat. To use them create, for example, a file $CATALINA_HOME/bin/setenv.sh with contents

export JAVA_OPTS="-server -Xmx512m"

For Windows you will need, in setenv.bat, something like

set JAVA_OPTS=-server -Xmx768m

Original answer here

After you run startup.bat, you can easily confirm the correct settings have been applied provided you have turned @echo on somewhere in your catatlina.bat file (a good place could be immediately after echo Using CLASSPATH: "%CLASSPATH%"):

Have a look at the WebRequestHandler Class and its ServerCertificateValidationCallback Property:

using (var handler = new WebRequestHandler())
{
    handler.ServerCertificateValidationCallback = ...

    using (var client = new HttpClient(handler))
    {
        ...
    }
}

A one liner with an IP address to country API

echo file_get_contents('https://ipapi.co/8.8.8.8/country_name/');

> United States

Example :

https://ipapi.co/country_name/ - your country

https://ipapi.co/8.8.8.8/country_name/ - country for IP 8.8.8.8

The suggested answer only works for certain versions of ruby. Some commenters suggest using ruby-dev; that didn't work for me either.

sudo apt-get install ruby-all-dev

worked for me.

The SQL WITH clause was introduced by Oracle in the Oracle 9i release 2 database. The SQL WITH clause allows you to give a sub-query block a name (a process also called sub-query refactoring), which can be referenced in several places within the main SQL query. The name assigned to the sub-query is treated as though it was an inline view or table. The SQL WITH clause is basically a drop-in replacement to the normal sub-query.

Syntax For The SQL WITH Clause

The following is the syntax of the SQL WITH clause when using a single sub-query alias.

WITH <alias_name> AS (sql_subquery_statement)
SELECT column_list FROM <alias_name>[,table_name]
[WHERE <join_condition>]

When using multiple sub-query aliases, the syntax is as follows.

WITH <alias_name_A> AS (sql_subquery_statement),
<alias_name_B> AS(sql_subquery_statement_from_alias_name_A
or sql_subquery_statement )
SELECT <column_list>
FROM <alias_name_A>, <alias_name_B> [,table_names]
[WHERE <join_condition>]

In the syntax documentation above, the occurrences of alias_name is a meaningful name you would give to the sub-query after the AS clause. Each sub-query should be separated with a comma Example for WITH statement. The rest of the queries follow the standard formats for simple and complex SQL SELECT queries.

Not the place to give a complete tutorial, but here it is in short;

RewriteCond basically means "execute the next RewriteRule only if this is true". The !-l path is the condition that the request is not for a link (! means not, -l means link)

The RewriteRule basically means that if the request is done that matches ^(.+)$ (matches any URL except the server root), it will be rewritten as index.php?url=$1 which means a request for ollewill be rewritten as index.php?url=olle).

QSA means that if there's a query string passed with the original URL, it will be appended to the rewrite (olle?p=1 will be rewritten as index.php?url=olle&p=1.

L means if the rule matches, don't process any more RewriteRules below this one.

For more complete info on this, follow the links above. The rewrite support can be a bit hard to grasp, but there are quite a few examples on stackoverflow to learn from.

You can always use TO_NUMBER() function in order to remove this error.This can be included as INSERT INTO employees phone_number values(TO_NUMBER('0419 853 694');

Use queue.rear+1 to get the length of the queue

try:
    value = raw_input()
    do_stuff(value) # next line was found 
except (EOFError):
   break #end of file reached

This seems to be proper usage of raw_input when dealing with the end of the stream of input from piped input. [Refer this post][1]

UPDATE:

This answer is outdated.

Like @jack-marchetti stated in his comment, and @devantoine with the link: https://developers.facebook.com/x/bugs/357750474364812/

Facebook has changed how the sharer.php works, as Ibrahim Faour replies to the bug filed with Facebook.

The sharer will no longer accept custom parameters and facebook will pull the information that is being displayed in the preview the same way that it would appear on facebook as a post, from the url OG meta tags.

Try this (via Javascript in this example):

'http://www.facebook.com/sharer.php?s=100&p[title]='+encodeURIComponent('this is a title') + '&p[summary]=' + encodeURIComponent('description here') + '&p[url]=' + encodeURIComponent('http://www.nufc.com') + '&p[images][0]=' + encodeURIComponent('http://www.somedomain.com/image.jpg')

I tried this quickly without the image part and the sharer.php window appears pre-populated, so it looks like a solution.

I found this via this SO article:

Want custom title / image / description in facebook share link from a flash app

and this link contained in an answer from Lelis718:

http://www.daddydesign.com/wordpress/how-to-create-a-custom-facebook-share-button-for-your-iframe-tab/

so all credit to Lelis718 for this answer.

[EDIT 3rd May 2013] - seems like the original URL i had here no longer works for me without also including "s=100" in the query string - no idea why but have updated accordingly

I'm going to expand your question a bit and also include the compile function.

• compile function - use for template DOM manipulation (i.e., manipulation of tElement = template element), hence manipulations that apply to all DOM clones of the template associated with the directive. (If you also need a link function (or pre and post link functions), and you defined a compile function, the compile function must return the link function(s) because the 'link' attribute is ignored if the 'compile' attribute is defined.)

• link function - normally use for registering listener callbacks (i.e., $watch expressions on the scope) as well as updating the DOM (i.e., manipulation of iElement = individual instance element). It is executed after the template has been cloned. E.g., inside an <li ng-repeat...>, the link function is executed after the <li> template (tElement) has been cloned (into an iElement) for that particular <li> element. A $watch allows a directive to be notified of scope property changes (a scope is associated with each instance), which allows the directive to render an updated instance value to the DOM.

• controller function - must be used when another directive needs to interact with this directive. E.g., on the AngularJS home page, the pane directive needs to add itself to the scope maintained by the tabs directive, hence the tabs directive needs to define a controller method (think API) that the pane directive can access/call.
  
  For a more in-depth explanation of the tabs and pane directives, and why the tabs directive creates a function on its controller using this (rather than on $scope), please see 'this' vs $scope in AngularJS controllers.

In general, you can put methods, $watches, etc. into either the directive's controller or link function. The controller will run first, which sometimes matters (see this fiddle which logs when the ctrl and link functions run with two nested directives). As Josh mentioned in a comment, you may want to put scope-manipulation functions inside a controller just for consistency with the rest of the framework.

This solve my problem.

Check this link . You were missing . before myButton. It was a small error. :)

.myButton{

file_get_contents() usually has permission issues. To avoid them, use:

function get_xml_from_url($url){
    $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13');

    $xmlstr = curl_exec($ch);
    curl_close($ch);

    return $xmlstr;
}

Example:

$xmlstr = get_xml_from_url('http://www.camara.gov.br/SitCamaraWS/Deputados.asmx/ObterDeputados');
$xmlobj = new SimpleXMLElement($xmlstr);
$xmlobj = (array)$xmlobj;//optional

Either you can use CSV functions or PHPExcel

or you can try like below

<?php
$file="demo.xls";
$test="<table  ><tr><td>Cell 1</td><td>Cell 2</td></tr></table>";
header("Content-type: application/vnd.ms-excel");
header("Content-Disposition: attachment; filename=$file");
echo $test;
?>

The header for .xlsx files is Content-type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet

There is this, which I credit to this blog:

@media only screen and (min-device-width: 560px) and (max-device-width: 1136px) and (-webkit-min-device-pixel-ratio: 2) {
    /* iPhone 5 only */
}

Keep in mind it reacts the iPhone 5, not to the particular iOS version installed on said device.

To merge with your existing version, you should be able to comma-delimit them:

@media only screen and (max-device-width: 480px), only screen and (min-device-width: 560px) and (max-device-width: 1136px) and (-webkit-min-device-pixel-ratio: 2) {
    /* iPhone only */
}

NB: I haven't tested the above code, but I've tested comma-delimited @media queries before, and they work just fine.

Note that the above may hit some other devices which share similar ratios, such as the Galaxy Nexus. Here is an additional method which will target only devices which have one dimension of 640px (560px due to some weird display-pixel anomalies) and one of between 960px (iPhone <5) and 1136px (iPhone 5).

@media
    only screen and (max-device-width: 1136px) and (min-device-width: 960px) and (max-device-height: 640px) and (min-device-height: 560px),
    only screen and (max-device-height: 1136px) and (min-device-height: 960px) and (max-device-width: 640px) and (min-device-width: 560px) {
    /* iPhone only */
}

I had the same problem and error. In my case it was the https_proxy not set. Setting the https_proxy environment variable fixed the issue.

$ export https_proxy=https://<porxy_addres>:<proxy_port>

Example:

$ export https_proxy=https://my.proxy.company.com:8000

Hope this help somebody.

It's not clear what type of application you're going to develop (desktop, web, console...)

The general answer, if you're developing Windows.Forms application, is use of

System.Windows.Forms.Timer class. The benefit of this is that it runs on UI thread, so it's simple just define it, subscribe to its Tick event and run your code on every 15 second.

If you do something else then windows forms (it's not clear from the question), you can choose System.Timers.Timer, but this one runs on other thread, so if you are going to act on some UI elements from the its Elapsed event, you have to manage it with "invoking" access.

As simple as:

$A="1"
function changeA2 () { $global:A="0"}
changeA2
$A

The internal set of single quotes in your code is killing the string. Whenever you hit a single quote it ends the string and continues processing. You'll want something like:

$thisstring = 'this string is long \' in needs escaped single quotes or nothing will run';

Use (localdb)\MSSQLLocalDB. That is the LocalDB instance intended for applications, independent of Visual Studio version.

Disregard my original answer: "With SQL Server 2014 Express LocalDB, use (localdb)\ProjectsV12. This works in both Visual Studio 2013 and SQL Server 2014 Management Studio." While ProjectsV12 will indeed give you a LocalDB instance, it's the wrong one, intended for use by SQL Server Data Tools.

You can kill two birds with one regex stone:

>>> r = """
... \n\tName: John Smith
... \n\t  Home: Anytown USA
... \n\t    Phone: 555-555-555
... \n\t  Other Home: Somewhere Else
... \n\t Notes: Other data
... \n\tName: Jane Smith
... \n\t  Misc: Data with spaces
... """
>>> import re
>>> print re.findall(r'(\S[^:]+):\s*(.*\S)', r)
[('Name', 'John Smith'), ('Home', 'Anytown USA'), ('Phone', '555-555-555'), ('Other Home', 'Somewhere Else'), ('Notes', 'Other data'), ('Name', 'Jane Smith'), ('Misc', 'Data with spaces')]
>>> 

Most people will tell you to check your proxy settings or delete and re-add artifacts, but I will stay away from that and give another suggestion in case that doesn't turn out to be your problem. It could be your mirror settings.

If you use maven at the office then there's a good chance maven is configured to look for your company's internal maven repository. If you're doing some work from home and you are not connected to the network this could be the problem. An obvious solution might be VPN to the office to get visibility to this repo. Another way around this is to add another mirror site to your /User/.m2/settings.xml file so if it fails to find it on your office network it will try public repo.

<mirror>
    <id>Central</id>
    <url>http://repo1.maven.org/maven2</url>
    <mirrorOf>central</mirrorOf>
    <!-- United States, St. Louis-->
</mirror>

For other maven repositories take a look here: http://docs.codehaus.org/display/MAVENUSER/Mirrors+Repositories

One of the JPA ways for getting only particular columns is to ask for a Tuple object.

In your case you would need to write something like this:

CriteriaQuery<Tuple> cq = builder.createTupleQuery();
// write the Root, Path elements as usual
Root<EntityClazz> root = cq.from(EntityClazz.class);
cq.multiselect(root.get(EntityClazz_.ID), root.get(EntityClazz_.VERSION));  //using metamodel
List<Tuple> tupleResult = em.createQuery(cq).getResultList();
for (Tuple t : tupleResult) {
    Long id = (Long) t.get(0);
    Long version = (Long) t.get(1);
}

Another approach is possible if you have a class representing the result, like T in your case. T doesn't need to be an Entity class. If T has a constructor like:

public T(Long id, Long version)

then you can use T directly in your CriteriaQuery constructor:

CriteriaQuery<T> cq = builder.createQuery(T.class);
// write the Root, Path elements as usual
Root<EntityClazz> root = cq.from(EntityClazz.class);
cq.multiselect(root.get(EntityClazz_.ID), root.get(EntityClazz_.VERSION));  //using metamodel
List<T> result = em.createQuery(cq).getResultList();

ExpressJS is bare-bones web application framework on top of NodeJS.

It can be used to build WebApps, RESTFUL APIs etc quickly.

Supports multiple template engines like Jade, EJS.

ExpressJS keeps only a minimalist functionality as core features and as such there are no ORMs or DBs supported as default. But with a little effort expressjs apps can be integrated with different databases.

For a getting started guide on creating ExpressJS apps, look into the following link:

use async:false attribute along with url and data. this will help to execute ajax call immediately and u can fetch and use data from server.

function functABC(){
    $.ajax({
        url: 'myPage.php',

        async:false
        success: function(data) {
            return data;
        }
    });
}

This is how I usually get current logged in user and their id in my templates.

MYISAM:

1. MYISAM supports Table-level Locking
2. MyISAM designed for need of speed
3. MyISAM does not support foreign keys hence we call MySQL with MYISAM is DBMS
4. MyISAM stores its tables, data and indexes in diskspace using separate three different files. (tablename.FRM, tablename.MYD, tablename.MYI)
5. MYISAM not supports transaction. You cannot commit and rollback with MYISAM. Once you issue a command it’s done.
6. MYISAM supports fulltext search
7. You can use MyISAM, if the table is more static with lots of select and less update and delete.

INNODB:

1. InnoDB supports Row-level Locking
2. InnoDB designed for maximum performance when processing high volume of data
3. InnoDB support foreign keys hence we call MySQL with InnoDB is RDBMS
4. InnoDB stores its tables and indexes in a tablespace
5. InnoDB supports transaction. You can commit and rollback with InnoDB

You do cls.isFilled = True. That overwrites the method called isFilled and replaces it with the value True. That method is now gone and you can't call it anymore. So when you try to call it again you get an error, since it's not there anymore.

The solution is use a different name for the variable than you do for the method.

You can do like this, to get the currently selected value:

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

& to get the currently selected text:

$('#myDropdownID:selected').text();
