iOS 11

Setting a custom button using constraint:

let buttonWidth = CGFloat(30)
let buttonHeight = CGFloat(30)

let button = UIButton(type: .custom)
button.setImage(UIImage(named: "img name"), for: .normal)
button.addTarget(self, action: #selector(buttonTapped(sender:)), for: .touchUpInside)
button.widthAnchor.constraint(equalToConstant: buttonWidth).isActive = true
button.heightAnchor.constraint(equalToConstant: buttonHeight).isActive = true

self.navigationItem.rightBarButtonItem = UIBarButtonItem.init(customView: button)

May this one help a little more

Let suppose if you want to make the bar button in a separate file(for modular approach) and want to give selector back to your viewcontroller, you can do like this :-

your Utility File

class GeneralUtility {

    class func customeNavigationBar(viewController: UIViewController,title:String){
        let add = UIBarButtonItem(title: "Play", style: .plain, target: viewController, action: #selector(SuperViewController.buttonClicked(sender:)));  
      viewController.navigationController?.navigationBar.topItem?.rightBarButtonItems = [add];
    }
}

Then make a SuperviewController class and define the same function on it.

class SuperViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
            // Do any additional setup after loading the view.
    }
    @objc func buttonClicked(sender: UIBarButtonItem) {

    }
}

and In our base viewController(which inherit your SuperviewController class) override the same function

import UIKit

class HomeViewController: SuperViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
    }

    override func viewWillAppear(_ animated: Bool) {
        GeneralUtility.customeNavigationBar(viewController: self,title:"Event");
    }

    @objc override func buttonClicked(sender: UIBarButtonItem) {
      print("button clicked")    
    } 
}

Now just inherit the SuperViewController in whichever class you want this barbutton.

Thanks for the read

I found a complete example of how to get this all to work so that you can always display a popover no matter the device/orientation https://github.com/frogcjn/AdaptivePopover_iOS8_Swift.

The key is to implement UIAdaptivePresentationControllerDelegate

func adaptivePresentationStyleForPresentationController(PC: UIPresentationController!) -> UIModalPresentationStyle {
    // This *forces* a popover to be displayed on the iPhone
    return .None
}

Then extend the example above (from Imagine Digital):

nav.popoverPresentationController!.delegate = implOfUIAPCDelegate

If you are not looking for a BarButtonItem but simple button on navigationBar then below code works:

UIButton *aButton = [UIButton buttonWithType:UIButtonTypeCustom];
[aButton setBackgroundImage:[UIImage imageNamed:@"NavBar.png"] forState:UIControlStateNormal];
[aButton addTarget:self
            action:@selector(showButtonView:)
  forControlEvents:UIControlEventTouchUpInside];
aButton.frame = CGRectMake(260.0, 10.0, 30.0, 30.0);
[self.navigationController.navigationBar addSubview:aButton];

Try adding the button to the navigationItem of the view controller that is going to be pushed onto this PropertyViewController class you have created.

That is:

MainViewController *vc = [[MainViewController alloc] initWithNibName:@"MainViewController" bundle:nil];
UIButton *infoButton = [UIButton buttonWithType:UIButtonTypeInfoLight];
[infoButton addTarget:self action:@selector(showInfo) forControlEvents:UIControlEventTouchUpInside];
vc.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithCustomView:infoButton] autorelease];

PropertyViewController *navController = [[PropertyViewController alloc] initWithRootViewController:vc];

Now, this infoButton that has been created programatically will show up in the navigation bar. The idea is that the navigation controller picks up its display information (title, buttons, etc) from the UIViewController that it is about to display. You don't actually add buttons and such directly to the UINavigationController.

Oracle doesn't have autoincrementing columns. You need a sequence and a trigger. Here's a random blog post that explains how to do it: http://www.lifeaftercoffee.com/2006/02/17/how-to-create-auto-increment-columns-in-oracle/

Are you trying to remove a single value or all matching values?

If you are trying to remove a single value, how do you define the value you wish to remove?

The reason you don't get a key back when querying on values is because the dictionary could contain multiple keys paired with the specified value.

If you wish to remove all matching instances of the same value, you can do this:

foreach(var item in dic.Where(kvp => kvp.Value == value).ToList())
{
    dic.Remove(item.Key);
}

And if you wish to remove the first matching instance, you can query to find the first item and just remove that:

var item = dic.First(kvp => kvp.Value == value);

dic.Remove(item.Key);

Note: The ToList() call is necessary to copy the values to a new collection. If the call is not made, the loop will be modifying the collection it is iterating over, causing an exception to be thrown on the next attempt to iterate after the first value is removed.

Implement the return statement like the example below! You should be good. I hope it helps someone..

class Example(object):
    def the_example(self):
        itsProblem = "problem"
        return itsProblem 


theExample = Example()
print theExample.the_example()

The Facebook API limit isn't really documented, but apparently it's something like: 600 calls per 600 seconds, per token & per IP. As the site is restricted, quoting the relevant part:

After some testing and discussion with the Facebook platform team, there is no official limit I'm aware of or can find in the documentation. However, I've found 600 calls per 600 seconds, per token & per IP to be about where they stop you. I've also seen some application based rate limiting but don't have any numbers.

As a general rule, one call per second should not get rate limited. On the surface this seems very restrictive but remember you can batch certain calls and use the subscription API to get changes.

As you can access the Graph API on the client side via the Javascript SDK; I think if you travel your request for photos from the client, you won't hit any application limit as it's the user (each one with unique id) who's fetching data, not your application server (unique ID).

This may mean a huge refactor if everything you do go through a server. But it seems like the best solution if you have so many request (as it'll give a breath to your server).

Else, you can try batch request, but I guess you're already going this way if you have big traffic.

If nothing of this works, according to the Facebook Platform Policy you should contact them.

If you exceed, or plan to exceed, any of the following thresholds please contact us as you may be subject to additional terms: (>5M MAU) or (>100M API calls per day) or (>50M impressions per day).

Beware of circular references when DOM objects are involved:

Memory leak patterns in JavaScript

Keep in mind that memory can only be reclaimed when there are no active references to the object. This is a common pitfall with closures and event handlers, as some JS engines will not check which variables actually are referenced in inner functions and just keep all local variables of the enclosing functions.

Here's a simple example:

function init() {
    var bigString = new Array(1000).join('xxx');
    var foo = document.getElementById('foo');
    foo.onclick = function() {
        // this might create a closure over `bigString`,
        // even if `bigString` isn't referenced anywhere!
    };
}

A naive JS implementation can't collect bigString as long as the event handler is around. There are several ways to solve this problem, eg setting bigString = null at the end of init() (delete won't work for local variables and function arguments: delete removes properties from objects, and the variable object is inaccessible - ES5 in strict mode will even throw a ReferenceError if you try to delete a local variable!).

I recommend to avoid unnecessary closures as much as possible if you care for memory consumption.

I just stumbled upon this great post. If you are just checking whether the data is of string type then maybe we can skip the loop and use this struct (in my humble opinion)

public static bool IsStringType(object data)
    {
        return (data.GetType().GetProperties().Where(x => x.PropertyType == typeof(string)).FirstOrDefault() != null);
    }

Nick Vogt at H3XED posted this syntax: https://www.youtube.com/v/VIDEOID?version=3&vq=hd1080

Take this link and replace the expression "VIDEOID" with the (shortened/shared) ID of the video.

Exapmple for ID: i3jNECZ3ybk looks like this: ... /v/i3jNECZ3ybk?version=3&vq=hd1080

What you get as a result is the standalone 1080p video but not in the Tube environment.

I also had problem with refused connection on port 80. I didn't use localhost.

curl --data-binary "@/textfile.txt" "http://www.myserver.com/123.php"

Problem was that I had umlauts äåö in my textfile.txt.

If you place image and css folder inside a parent directory suppose assets then the following code works perfectly. Either double quote or without a double quote both work fine.

body{_x000D_
   background: url("../image/bg.jpg");_x000D_
}

In other cases like if you call a class and try to put a background image in a particular location then you must mention height and width as well.

You need

/^[a-zA-Z]+$/

Currently, you are matching a single character at the start of the input. If your goal is to match letter characters (one or more) from start to finish, then you need to repeat the a-z character match (using +) and specify that you want to match all the way to the end (via $)

Suggestions:

• Create a File object that refers to the already existing file on disk.
• Use a FileWriter object, and use the constructor that takes the File object and a boolean, the latter if true would allow appending text into the File if it exists.
• Then initialize a PrintWriter passing in the FileWriter into its constructor.
• Then call println(...) on your PrintWriter, writing your new text into the file.
• As always, close your resources (the PrintWriter) when you are done with it.
• As always, don't ignore exceptions but rather catch and handle them.
• The close() of the PrintWriter should be in the try's finally block.

e.g.,

  PrintWriter pw = null;

  try {
     File file = new File("fubars.txt");
     FileWriter fw = new FileWriter(file, true);
     pw = new PrintWriter(fw);
     pw.println("Fubars rule!");
  } catch (IOException e) {
     e.printStackTrace();
  } finally {
     if (pw != null) {
        pw.close();
     }
  }

Easy, no?

Thanks all. I took bits of each of your solutions and made my own.

The final working solution is:

<script type="text/javascript">
    $(document).ready(function(){
        $.ajax({
            url: '<?php bloginfo('template_url'); ?>/functions/twitter.php',
            data: "tweets=<?php echo $ct_tweets; ?>&account=<?php echo $ct_twitter; ?>",
            success: function(data) {
                $('#twitter-loader').remove();
                $('#twitter-container').html(data);
            }
        });
   });
</script>

Answer by Adamski is a good one and describes the steps in an encoding operation when using the general encode method (that takes a byte buffer as one of the inputs)

However, the method in question (in this discussion) is a variant of encode - encode(CharBuffer in). This is a convenience method that implements the entire encoding operation. (Please see java docs reference in P.S.)

As per the docs, This method should therefore not be invoked if an encoding operation is already in progress (which is what is happening in ZenBlender's code -- using static encoder/decoder in a multi threaded environment).

Personally, I like to use convenience methods (over the more general encode/decode methods) as they take away the burden by performing all the steps under the covers.

ZenBlender and Adamski have already suggested multiple ways options to safely do this in their comments. Listing them all here:

• Create a new encoder/decoder object when needed for each operation (not efficient as it could lead to a large number of objects). OR,
• Use a ThreadLocal to avoid creating new encoder/decoder for each operation. OR,
• Synchronize the entire encoding/decoding operation (this might not be preferred unless sacrificing some concurrency is ok for your program)

P.S.

java docs references:

1. Encode (convenience) method: http://docs.oracle.com/javase/6/docs/api/java/nio/charset/CharsetEncoder.html#encode%28java.nio.CharBuffer%29
2. General encode method: http://docs.oracle.com/javase/6/docs/api/java/nio/charset/CharsetEncoder.html#encode%28java.nio.CharBuffer,%20java.nio.ByteBuffer,%20boolean%29

This is my solution to scroll to the top on a button click.

$(".btn").click(function () {
if ($(this).text() == "Show options") {
$(".tabs").animate(
  {
    scrollTop: $(window).scrollTop(0)
  },
  "slow"
 );
 }
});

select u from UserGroup ug inner join ug.user u 
where ug.group_id = :groupId 
order by u.lastname

As a named query:

@NamedQuery(
  name = "User.findByGroupId",
  query =
    "SELECT u FROM UserGroup ug " +
    "INNER JOIN ug.user u WHERE ug.group_id = :groupId ORDER BY u.lastname"
)

Use paths in the HQL statement, from one entity to the other. See the Hibernate documentation on HQL and joins for details.

This code will help you to make a repeating alarm. The repeating time can set by you.

If you need alarm only for a single time then replace

alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), result , pendingIntent);

with

 alarmManager.set( AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + result , pendingIntent );

You may also try mongoosejs's lean() :

UserModel.find().lean().exec(function (err, users) {
    return res.end(JSON.stringify(users));
}

After taking an interactive tutorial I ended up with a bunch of pods, services, deployments:

me@pooh ~ > kubectl get pods,services

To clean up everything, delete --all worked fine:

pod "kubernetes-bootcamp-5c69669756-v8vd4" deleted
service "kubernetes" deleted
deployment.extensions "kubernetes-bootcamp" deleted

That left me with (what I think is) an empty Kubernetes cluster:

Assuming that the question is asking what's the minimum bits required for you to store

1. 3 digits number

My approach to this question would be:

• what's the maximum number of 3 digits number we need to store? Ans: 999
• what's the minimum amount of bits required for me to store this number?

This problem can be solved this way by dividing 999 by 2 recursively. However, it's simpler to use the power of maths to help us. Essentially, we're solving n for the equation below:

2^n = 999
nlog2 = log999
n ~ 10

You'll need 10 bits to store 3 digit number.

Use similar approach to solve the other subquestions!

Hope this helps!

Surprised no one mentioned a simple if statement can make sure your loop only gets executed once per format (on the first column, of the first row).

    private void dgv_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
    {
        // once per format
        if (e.ColumnIndex == 0 && e.RowIndex == 0)
        {
            foreach (DataGridViewRow row in dgv.Rows)
                if (row != null)
                    row.DefaultCellStyle.BackColor = Color.Red;
        }
    }

Compatibility Guide for JDK 8 says that in Java 8 the command line flag MaxPermSize has been removed. The reason is that the permanent generation was removed from the hotspot heap and was moved to native memory. So in order to remove this message edit MAVEN_OPTS Environment User Variable:

Java 7

MAVEN_OPTS -Xmx512m -XX:MaxPermSize=128m

Java 8

MAVEN_OPTS -Xmx512m

Update your environment variables

Ensure the reference to java/bin is up to date in 'Path'; This may be automatic if you have JAVA_HOME or equivalent set. If JAVA_HOME is set, simply update it to refer to the older JRE installation.

You can use concat:

In [11]: pd.concat([df1['c'], df2['c']], axis=1, keys=['df1', 'df2'])
Out[11]: 
                 df1       df2
2014-01-01       NaN -0.978535

2014-01-07       NaN -0.024608
2014-01-08       NaN -1.791899

[8 rows x 2 columns]

The axis argument determines the way the DataFrames are stacked:

df1 = pd.DataFrame([1, 2, 3])
df2 = pd.DataFrame(['a', 'b', 'c'])

pd.concat([df1, df2], axis=0)
   0
0  1
1  2
2  3
0  a
1  b
2  c

pd.concat([df1, df2], axis=1)

   0  0
0  1  a
1  2  b
2  3  c

This is a really old question but it has a high ranking in Google so I'm going to throw in my method which could work depending on your needs.

In my case, I wanted a thick dashed border that had a minimal break in between dashes. I used a CSS pattern generator (like this one: http://www.patternify.com/) to create a 10px wide by 1px tall pattern. 9px of that is solid dash color, 1px is white.

In my CSS, I included that pattern as the background image, and then scaled it up by using the background-size attribute. I ended up with a 20px by 2px repeated dash, 18px of that being solid line and 2px white. You could scale it up even more for a really thick dashed line.

The nice thing is since the image is encoded as data you don't have the additional outside HTTP request, so there's no performance burden. I stored my image as a SASS variable so I could reuse it in my site.

I thought i'd expand on the above answer by talking about how you'd fit modules together into an application. I'd read about this in the doug crockford book but being new to javascript it was all still a bit mysterious.

I come from a c# background so have added some terminology I find useful from there.

Html

You'll have some kindof top level html file. It helps to think of this as your project file. Every javascript file you add to the project wants to go into this, unfortunately you dont get tool support for this (I'm using IDEA).

You need add files to the project with script tags like this:

        <script type="text/javascript" src="app/native/MasterFile.js" /></script>
        <script type="text/javascript" src="app/native/SomeComponent.js" /></script>

It appears collapsing the tags causes things to fail - whilst it looks like xml it's really something with crazier rules!

Namespace file

MasterFile.js

myAppNamespace = {};

that's it. This is just for adding a single global variable for the rest of our code to live in. You could also declare nested namespaces here (or in their own files).

Module(s)

SomeComponent.js

myAppNamespace.messageCounter= (function(){

    var privateState = 0;

    var incrementCount = function () {
        privateState += 1;
    };

    return function (message) {
        incrementCount();
        //TODO something with the message! 
    }
})();

What we're doing here is assigning a message counter function to a variable in our application. It's a function which returns a function which we immediately execute.

Concepts

I think it helps to think of the top line in SomeComponent as being the namespace where you are declaring something. The only caveat to this is all your namespaces need to appear in some other file first - they are just objects rooted by our application variable.

I've only taken minor steps with this at the moment (i'm refactoring some normal javascript out of an extjs app so I can test it) but it seems quite nice as you can define little functional units whilst avoiding the quagmire of 'this'.

You can also use this style to define constructors by returning a function which returns an object with a collection of functions and not calling it immediately.

As of iOS 10 there is also a new block based Timer factory method which is cleaner than using the selector:

    _ = Timer.scheduledTimer(withTimeInterval: 5, repeats: false) { timer in
        label.isHidden = true
    }

1 - In your podfile, remove the pod that creates a problem, and save the file 2 - Run pod install 3 - Re-add the pod, save the file 4 - Re-run pod install

Problem should be solved.

This works for me in IE 7, FF 3.5, Chrome 3b, Safari 4 (Windows).

Also works in IE 6 if you uncomment the clearer div at the bottom. Edit: as Natalie Downe said, you can simply add width: 100%; to #container instead.

I don't know a CSS way to vertically center the text in the right div if the div isn't of fixed height. If it is, you can set the line-height to the same value as the div height and put an inner div containing your text with display: inline; line-height: 110%.

I have used this:

mongorestore -d databasename -c file.bson fullpath/file.bson

1.copy the file path and file name from properties (try to put all bson files in different folder), 2.use this again and again with changing file name only.

You cannot add default values for function parameters. But you can do this:

function tester(paramA, paramB){
 if (typeof paramA == "undefined"){
   paramA = defaultValue;
 }
 if (typeof paramB == "undefined"){
   paramB = defaultValue;
 }
}

I'm working with zip files which Java's ZipFile class isn't able to handle. Java 8 apparently can't handle compression method 12 (bzip2 I believe). After trying a number of methods including zip4j (which also fails with these particular files due to another issue), I had success with Apache's commons-compress which supports additional compression methods as mentioned here.

Note that the ZipFile class below is not the one from java.util.zip.

It's actually org.apache.commons.compress.archivers.zip.ZipFile so be careful with the imports.

try (ZipFile zipFile = new ZipFile(archiveFile)) {
    Enumeration<ZipArchiveEntry> entries = zipFile.getEntries();
    while (entries.hasMoreElements()) {
        ZipArchiveEntry entry = entries.nextElement();
        File entryDestination = new File(destination, entry.getName());
        if (entry.isDirectory()) {
            entryDestination.mkdirs();
        } else {
            entryDestination.getParentFile().mkdirs();
            try (InputStream in = zipFile.getInputStream(entry); OutputStream out = new FileOutputStream(entryDestination)) {
                IOUtils.copy(in, out);
            }
        }
    }
} catch (IOException ex) {
    log.debug("Error unzipping archive file: " + archiveFile, ex);
}

For Gradle:

compile 'org.apache.commons:commons-compress:1.18'

It comes down to whether the feature is used by one person or if others are working off of it.

You can force the push after the rebase if it's just you:

git push origin feature -f

However, if others are working on it, you should merge and not rebase off of master.

git merge master
git push origin feature

This will ensure that you have a common history with the people you are collaborating with.

On a different level, you should not be doing back-merges. What you are doing is polluting your feature branch's history with other commits that don't belong to the feature, making subsequent work with that branch more difficult - rebasing or not.

This is my article on the subject called branch per feature.

Hope this helps.

Expanding on the answer from Grin/Dan Abramov, this works across multiple input types. Tested in React >= 15.5

const inputTypes = [
    window.HTMLInputElement,
    window.HTMLSelectElement,
    window.HTMLTextAreaElement,
];

export const triggerInputChange = (node, value = '') => {

    // only process the change on elements we know have a value setter in their constructor
    if ( inputTypes.indexOf(node.__proto__.constructor) >-1 ) {

        const setValue = Object.getOwnPropertyDescriptor(node.__proto__, 'value').set;
        const event = new Event('input', { bubbles: true });

        setValue.call(node, value);
        node.dispatchEvent(event);

    }

};

I don't think there is a way to ignore adding DEFINERs to the dump. But there are ways to remove them after the dump file is created.

1. Open the dump file in a text editor and replace all occurrences of DEFINER=root@localhost with an empty string ""

2. Edit the dump (or pipe the output) using perl:

   perl -p -i.bak -e "s/DEFINER=\`\w.*\`@\`\d[0-3].*[0-3]\`//g" mydatabase.sql
   

3. Pipe the output through sed:

   mysqldump ... | sed -e 's/DEFINER[ ]*=[ ]*[^*]*\*/\*/' > triggers_backup.sql
   

Late to the party, but the current answers won't work if you have box-sizing: border-box set (which a lot of people do for form elements these days).

Just reset the box sizing for IE8 to box-sizing: content-box; then use one of the padding / height answer.

I think it's better to round the time to milliseconds before the division.

func makeTimestamp() int64 {
    return time.Now().Round(time.Millisecond).UnixNano() / (int64(time.Millisecond)/int64(time.Nanosecond))
}

Here is an example program:

package main

import (
        "fmt"
        "time"
)

func main() {
        fmt.Println(unixMilli(time.Unix(0, 123400000)))
        fmt.Println(unixMilli(time.Unix(0, 123500000)))
        m := makeTimestampMilli()
        fmt.Println(m)
        fmt.Println(time.Unix(m/1e3, (m%1e3)*int64(time.Millisecond)/int64(time.Nanosecond)))
}

func unixMilli(t time.Time) int64 {
        return t.Round(time.Millisecond).UnixNano() / (int64(time.Millisecond) / int64(time.Nanosecond))
}

func makeTimestampMilli() int64 {
        return unixMilli(time.Now())
}

The above program printed the result below on my machine:

123

System environment variables are globally accessed by all users.
User environment variables are specific only to the currently logged-in user.

you need to create a new ssh key by typing the following - ssh-keygen -t rsa

Then you need to add: - heroku keys:add

Then if you type - heroku open

The problem has been solved.

It worked for me anyway, you could give it a try...

it is just a sample to avoid max recursion error. we have to use option (maxrecursion 365); or option (maxrecursion 0);

DECLARE @STARTDATE datetime; 
DECLARE @EntDt datetime; 
set @STARTDATE = '01/01/2009';  
set @EntDt = '12/31/2009'; 
declare @dcnt int; 
;with DateList as   
 (   
    select @STARTDATE DateValue   
    union all   
    select DateValue + 1 from    DateList      
    where   DateValue + 1 < convert(VARCHAR(15),@EntDt,101)   
 )   
  select count(*) as DayCnt from (   
  select DateValue,DATENAME(WEEKDAY, DateValue ) as WEEKDAY from DateList
  where DATENAME(WEEKDAY, DateValue ) not IN ( 'Saturday','Sunday' )     
  )a
option (maxrecursion 365);

First, you need to understand that you have two documents: The frame and the container (which contains the frame).

The main obstacle with manipulating the frame from the container is that the frame loads asynchronously. You can't simply access it any time, you must know when it has finished loading. So you need a trick. The usual solution is to use window.parent in the frame to get "up" (into the document which contains the iframe tag).

Now you can call any method in the container document. This method can manipulate the frame (for example call some JavaScript in the frame with the parameters you need). To know when to call the method, you have two options:

1. Call it from body.onload of the frame.

2. Put a script element as the last thing into the HTML content of the frame where you call the method of the container (left as an exercise for the reader).

So the frame looks like this:

<script>
function init() { window.parent.setUpFrame(); return true; }
function yourMethod(arg) { ... }
</script>
<body onload="init();">...</body>

And the container like this:

<script>
function setUpFrame() { 
    var frame = window.frames['frame-id'];
    frame.yourMethod('hello');
}
</script>
<body><iframe name="frame-id" src="..."></iframe></body>

There is a special security expression in spring security:

hasAnyRole(list of roles) - true if the user has been granted any of the roles specified (given as a comma-separated list of strings).

I have never used it but I think it is exactly what you are looking for.

Example usage:

<security:authorize access="hasAnyRole('ADMIN', 'DEVELOPER')">
    ...
</security:authorize>

Here is a link to the reference documentation where the standard spring security expressions are described. Also, here is a discussion where I described how to create custom expression if you need it.

From the Java Documentation:

[...] More surprisingly, class Class has been generified. Class literals now function as type tokens, providing both run-time and compile-time type information. This enables a style of static factories exemplified by the getAnnotation method in the new AnnotatedElement interface:

<T extends Annotation> T getAnnotation(Class<T> annotationType); 

This is a generic method. It infers the value of its type parameter T from its argument, and returns an appropriate instance of T, as illustrated by the following snippet:

Author a = Othello.class.getAnnotation(Author.class);

Prior to generics, you would have had to cast the result to Author. Also you would have had no way to make the compiler check that the actual parameter represented a subclass of Annotation. [...]

Well, I never had to use this kind of stuff. Anyone?

Go to the "ProjectName" , click on it , and then go the "Build phases" tab , and then click on the "compile sources" , and then click on "+" button , a window will appear , the choose "MyClass.m" file and then click "add" ,

Build the Project and Run it , the problem will surely get solved out

You can finish the Acivity and recreate it afterwards in this way your activity will be created again and all the views will be created with the new theme.

Thanks all for your help but it is not complicated as it seems; almost everything is handled internally by SpringBoot.

In my case I want to use Mysql and Mongodb and the solution was to use EnableMongoRepositories and EnableJpaRepositories annotations on to my application class.

@SpringBootApplication
@EnableTransactionManagement
@EnableMongoRepositories(includeFilters = @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, value = MongoRepository))
@EnableJpaRepositories(excludeFilters = @ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, value = MongoRepository))
class TestApplication { ...

NB: All mysql entities have to extend JpaRepository and mongo enities have to extend MongoRepository.

The datasource configs are straight forward as presented by spring documentation:

//mysql db config
spring.datasource.url= jdbc:mysql://localhost:3306/tangio
spring.datasource.username=test
spring.datasource.password=test

#mongodb config
spring.data.mongodb.host=localhost
spring.data.mongodb.port=27017
spring.data.mongodb.database=tangio
spring.data.mongodb.username=tangio
spring.data.mongodb.password=tangio
spring.data.mongodb.repositories.enabled=true

CREATE PROCEDURE [dbo].[Usp_GetColumnName]      
        @TableName varchar(50)
AS
BEGIN   
    BEGIN
        SET NOCOUNT ON
        IF (@TableName IS NOT NULL) 
            select ORDINAL_POSITION OrderPosition,COLUMN_NAME ColumnName from information_schema.columns 
             where table_name =@TableName
             order by ORDINAL_POSITION
    END
END

Using def change means you should write migrations that are reversible. And change_column is not reversible. You can go up but you cannot go down, since change_column is irreversible.

Instead, though it may be a couple extra lines, you should use def up and def down

So if you have a column with no default value, then you should do this to add a default value.

def up
  change_column :users, :admin, :boolean, default: false
end

def down
  change_column :users, :admin, :boolean, default: nil
end

Or if you want to change the default value for an existing column.

def up
  change_column :users, :admin, :boolean, default: false
end

def down
  change_column :users, :admin, :boolean, default: true
end

The issue is that a notebooks is not a plain python file. The steps to import the .ipynb file are outlined in the following: Importing notebook

I am pasting the code, so if you need it...you can just do a quick copy and paste. Notice that at the end I have the import primes statement. You'll have to change that of course. The name of my file is primes.ipynb. From this point on you can use the content inside that file as you would do regularly.

Wish there was a simpler method, but this is straight from the docs.

exception.toString does not give you the StackTrace, it only returns

a short description of this throwable. The result is the concatenation of:

Use exception.printStackTrace instead to output the StackTrace.

If you are using Java 6 or higher you can use wildcards of this form:

java -classpath ".;c:\mylibs\*;c:\extlibs\*" MyApp

If you would like to add all subdirectories: lib\a\, lib\b\, lib\c\, there is no mechanism for this in except:

java -classpath ".;c:\lib\a\*;c:\lib\b\*;c:\lib\c\*" MyApp

There is nothing like lib\*\* or lib\** wildcard for the kind of job you want to be done.

If you use UPPER(text), the like '%lah%' will always return zero results. Use '%LAH%'.

You can upgrade to Subversion 1.7. In order to update to Subversion 1.7 you have to launch existing project in Xcode 5 or above. This will prompt an warning ‘The working copy ProjectName should be upgraded to Subversion 1.7’ (shown in below screenshot).

You should select ‘Upgrade’ button to upgrade to Subversion 1.7. This will take a bit of time.

If you are using terminal then you can upgrade to Subversion 1.7 by running below command in your project directory: svn upgrade

Note that once you have upgraded to Subversion 1.7 you cannot go back to Subversion 1.6.

Once I faced with the issue when I did not know which the element currently stored in my variable (svg or html) but I needed to get it width and height. I created this function and want to share it:

function computeDimensions(selection) {
  var dimensions = null;
  var node = selection.node();

  if (node instanceof SVGGraphicsElement) { // check if node is svg element
    dimensions = node.getBBox();
  } else { // else is html element
    dimensions = node.getBoundingClientRect();
  }
  console.log(dimensions);
  return dimensions;
}

Little demo in the hidden snippet below. We handle click on the blue div and on the red svg circle with the same function.

var svg = d3.select('svg')
  .attr('width', 50)
  .attr('height', 50);

function computeDimensions(selection) {
    var dimensions = null;
  var node = selection.node();

  if (node instanceof SVGElement) {
    dimensions = node.getBBox();
  } else {
    dimensions = node.getBoundingClientRect();
  }
  console.clear();
  console.log(dimensions);
  return dimensions;
}

var circle = svg
    .append("circle")
    .attr("r", 20)
    .attr("cx", 30)
    .attr("cy", 30)
    .attr("fill", "red")
    .on("click", function() { computeDimensions(circle); });
    
var div = d3.selectAll("div").on("click", function() { computeDimensions(div) });

In python 3.x. you use

print("Hello, World")

In Python 2.x. you use

print "Hello, World!"

In general, you should favor interfaces over abstract classes. One reason to use an abstract class is if you have common implementation among concrete classes. Of course, you should still declare an interface (IPet) and have an abstract class (PetBase) implement that interface.Using small, distinct interfaces, you can use multiples to further improve flexibility. Interfaces allow the maximum amount of flexibility and portability of types across boundaries. When passing references across boundaries, always pass the interface and not the concrete type. This allows the receiving end to determine concrete implementation and provides maximum flexibility. This is absolutely true when programming in a TDD/BDD fashion.

The Gang of Four stated in their book "Because inheritance exposes a subclass to details of its parent's implementation, it's often said that 'inheritance breaks encapsulation". I believe this to be true.

1. Create a file inside /etc/nginx/sites-available and call it whatever you want, I'll call it django since it's a djanog server

   sudo touch /etc/nginx/sites-available/django
   

2. Then create a symlink that points to it

   sudo ln -s /etc/nginx/sites-available/django /etc/nginx/sites-enabled
   

3. Then edit that file with whatever file editor you use, vim or nano or whatever and create the server inside it

   server {
       # hostname or ip or multiple separated by spaces
       server_name localhost example.com 192.168.1.1; #change to your setting
       location / {
           root /home/techcee/scrapbook/local/lib/python2.7/site-packages/django/__init__.pyc/;
       }
   }
   

4. Restart or reload nginx settings

   sudo service nginx reload
   

Note I believe that your configuration like this probably won't work yet because you need to pass it to a fastcgi server or something, but at least this is how you could create a valid server

I was solving same problem recently. I was designing a write cmdlet for my Subtitle module. I had six different user stories:

• Subtitle only
• Subtitle and path (original file name is used)
• Subtitle and new file name (original path is used)
• Subtitle and name suffix is used (original path and modified name is used).
• Subtile, new path and new file name is is used.
• Subtitle, new path and suffix is used.

I end up in the big frustration because I though that 4 parameters will be enough. Like most of the times, the frustration was pointless because it was my fault. I didn't know enough about parameter sets.

After some research in documentation, I realized where is the problem. With knowledge how the parameter sets should be used, I developed a general and simple approach how to solve this problem. A pencil and a sheet of paper is required but a spreadsheet editor is better:

1. Write down all intended ways how the cmdlet should be used => user stories.
2. Keep adding parameters with meaningful names and mark the use of the parameters until you have a unique collection set => no repetitive combination of parameters.
3. Implement parameter sets into your code.
4. Prepare tests for all possible user stories.
5. Run tests (big surprise, right?). IDEs doesn't checks parameter sets collision, tests could save lots of trouble later one.

Example:

The practical example could be seen over here.

BTW: The parameter uniqueness within parameter sets is the reason why the ParameterSetName property doesn't support [String[]]. It doesn't really make any sense.

I've heard that using sudo with pip is unsafe.

Try adding --user to the end of your command, as mentioned here.

pip install packageName --user

I suspect that installing with this method means the packages are not available to other users.

Set 2 properties below:

1. extendedState = 6
2. resizeable = true

It works for me.

You have to add the following code in the manifest.xml file. The activity for which it should not rotate, in that activity add this element

android:screenOrientation="portrait"

Then it will not rotate.

Use this :

public View getViewByPosition(int pos, ListView listView) {
    final int firstListItemPosition = listView.getFirstVisiblePosition();
    final int lastListItemPosition = firstListItemPosition + listView.getChildCount() - 1;

    if (pos < firstListItemPosition || pos > lastListItemPosition ) {
        return listView.getAdapter().getView(pos, null, listView);
    } else {
        final int childIndex = pos - firstListItemPosition;
        return listView.getChildAt(childIndex);
    }
}

Since java 1.5 you can also pass a java.net.Proxy instance to the openConnection(proxy) method:

//Proxy instance, proxy ip = 10.0.0.1 with port 8080
Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("10.0.0.1", 8080));
conn = new URL(urlString).openConnection(proxy);

If your proxy requires authentication it will give you response 407.

In this case you'll need the following code:

    Authenticator authenticator = new Authenticator() {

        public PasswordAuthentication getPasswordAuthentication() {
            return (new PasswordAuthentication("user",
                    "password".toCharArray()));
        }
    };
    Authenticator.setDefault(authenticator);

Common Causes

The common causes for "Undefined symbols for architecture armv7" are:

1. You import a header and do not link against the correct library. This is common, especially for headers for libraries like QuartzCore since it is not included in projects by default. To resolve:

   • Add the correct libraries in the Link Binary With Libraries section of the Build Phases.

   • If you want to add a library outside of the default search path you can include the path in the Library Search Paths value in the Build Settings and add
     -l{library_name_without_lib_and_suffix} (eg. for libz.a use -lz) to the Other Linker Flags section of Build Settings.
     
     

2. You copy files into your project but forgot to check the target to add the files to. To resolve:

   • Open the Build Phases for the correct target, expand Compile Sources and add the missing .m files. If this is your issue please upvote Cortex's answer below as well.
     
     

3. You include a static library that is built for another architecture like i386, the simulator on your host machine. To resolve:

   • If you have multiple library files from your libraries vendor to include in the project you need to include the one for the simulator (i386) and the one for the device (armv7 for example).

   • Optionally, you could create a fat static library that contains both architectures.

Original Answer:

You have not linked against the correct libz file. If you right click the file and reveal in finder its path should be somewhere in an iOS sdk folder. Here is mine for example

/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk/usr/lib

I recommend removing the reference and then re-adding it back in the Link Binary With Libraries section Build Phases of your target.

Just wanted to say that Bootstrap 3 handles this a bit differently. The event name is "shown.bs.modal".

$('#themodal').on('shown.bs.modal', function () {
   $("#txtname").focus();
});

or put the focus on the first visible input like this:

.modal('show').on('shown.bs.modal', function ()
{
    $('input:visible:first').focus();
})

I also ran across this while trying to use google_play_services_froyo.

I filed this bug: https://code.google.com/p/google-plus-platform/issues/detail?id=734

Here is another answer:

.AddItem "Chinese"
.AddItem "Frites and Meat"
End With 

Source: Show the

You probably want to change the condition to if ($(this).hasClass('active'))

Also, hasClass and addClass take classnames, not selectors.
Therefore, you shouldn't include a ..

to_skip = ("bad", "naughty")
out_handle = open("testout", "w")

with open("testin", "r") as handle:
    for line in handle:
        if set(line.split(" ")).intersection(to_skip):
            continue
        out_handle.write(line)
out_handle.close()

Add reference > Browse > C: > Windows > assembly > GAC > Microsoft.Office.Interop.Excel > 12.0.0.0_wasd.. > Microsoft.Office.Interop.Excel.dll

You have change proper version of the JAVA_HOME and PATH in environmental variables.

TL;DR:

The ActionListeners (there can be multiple) execute in the order they were registered BEFORE the action

Long Answer:

A business action typically invokes an EJB service and if necessary also sets the final result and/or navigates to a different view if that is not what you are doing an actionListener is more appropriate i.e. for when the user interacts with the components, such as h:commandButton or h:link they can be handled by passing the name of the managed bean method in actionListener attribute of a UI Component or to implement an ActionListener interface and pass the implementation class name to actionListener attribute of a UI Component.

Use the util namespace, you will be able to register the list as a bean in your application context. You can then reuse the list to inject it in other bean definitions.

Setting 'checked' or null instead of true or false respectively will do the work.

// checkbox selection
var $chk=$(':checkbox');
$chk.prop('checked',$chk.is(':checked') ? null:'checked');

|| chr(38) ||

This solution is perfect.

I would suggest to use ExpectedConditions and alertIsPresent(). ExpectedConditions is a wrapper class that implements useful conditions defined in ExpectedCondition interface.

WebDriverWait wait = new WebDriverWait(driver, 300 /*timeout in seconds*/);
if(wait.until(ExpectedConditions.alertIsPresent())==null)
    System.out.println("alert was not present");
else
    System.out.println("alert was present");

I've created a tool that generates TypeScript interfaces and a runtime "type map" for performing runtime typechecking against the results of JSON.parse: ts.quicktype.io

For example, given this JSON:

{
  "name": "David",
  "pets": [
    {
      "name": "Smoochie",
      "species": "rhino"
    }
  ]
}

quicktype produces the following TypeScript interface and type map:

export interface Person {
    name: string;
    pets: Pet[];
}

export interface Pet {
    name:    string;
    species: string;
}

const typeMap: any = {
    Person: {
        name: "string",
        pets: array(object("Pet")),
    },
    Pet: {
        name: "string",
        species: "string",
    },
};

Then we check the result of JSON.parse against the type map:

export function fromJson(json: string): Person {
    return cast(JSON.parse(json), object("Person"));
}

I've left out some code, but you can try quicktype for the details.

== and != work on object identity. While the two Strings have the same value, they are actually two different objects.

use !"success".equals(statusCheck) instead.

So there might be a few things wrong here.

First start by reading how to use XMLHttpRequest.open() because there's a third optional parameter for specifying whether to make an asynchronous request, defaulting to true. That means you're making an asynchronous request and need to specify a callback function before you do the send(). Here's an example from MDN:

var oXHR = new XMLHttpRequest();

oXHR.open("GET", "http://www.mozilla.org/", true);

oXHR.onreadystatechange = function (oEvent) {
    if (oXHR.readyState === 4) {
        if (oXHR.status === 200) {
          console.log(oXHR.responseText)
        } else {
           console.log("Error", oXHR.statusText);
        }
    }
};

oXHR.send(null);

Second, since you're getting a 101 error, you might use the wrong URL. So make sure that the URL you're making the request with is correct. Also, make sure that your server is capable of serving your quiz.xml file.

You'll probably have to debug by simplifying/narrowing down where the problem is. So I'd start by making an easy synchronous request so you don't have to worry about the callback function. So here's another example from MDN for making a synchronous request:

var request = new XMLHttpRequest();
request.open('GET', 'file:///home/user/file.json', false); 
request.send(null);

if (request.status == 0)
    console.log(request.responseText);

Also, if you're just starting out with Javascript, you could refer to MDN for Javascript API documentation/examples/tutorials.

AllowOverride AuthConfig

try this. Authentication may be the problem. I was working with a CGI script written in C++, and faced some authentication issues when passed DELETE. The above solution helped me. It may help in your case too.

Also even if you don't get the solution for your problem of PUT and DELETE, do not stop working rather use "CORS". It is a google chrome app, which will help you bypass the problem, but remember it is a temporary solution, so that your work or experiments doesn't remain freeze for long. Obviously, you cannot ask your client to have "CORS" enabled to run your solution, as it may compromise systems security.

Wherein I Answer the Question That Was Asked

Why doesn't Python offer it out of the box?

I suspect that it has to do with the Zen of Python: "There should be one -- and preferably only one -- obvious way to do it." This would create two obvious ways to access values from dictionaries: obj['key'] and obj.key.

Caveats and Pitfalls

These include possible lack of clarity and confusion in the code. i.e., the following could be confusing to someone else who is going in to maintain your code at a later date, or even to you, if you're not going back into it for awhile. Again, from Zen: "Readability counts!"

>>> KEY = 'spam'
>>> d[KEY] = 1
>>> # Several lines of miscellaneous code here...
... assert d.spam == 1

If d is instantiated or KEY is defined or d[KEY] is assigned far away from where d.spam is being used, it can easily lead to confusion about what's being done, since this isn't a commonly-used idiom. I know it would have the potential to confuse me.

Additonally, if you change the value of KEY as follows (but miss changing d.spam), you now get:

>>> KEY = 'foo'
>>> d[KEY] = 1
>>> # Several lines of miscellaneous code here...
... assert d.spam == 1
Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
AttributeError: 'C' object has no attribute 'spam'

IMO, not worth the effort.

Other Items

As others have noted, you can use any hashable object (not just a string) as a dict key. For example,

>>> d = {(2, 3): True,}
>>> assert d[(2, 3)] is True
>>> 

is legal, but

>>> C = type('C', (object,), {(2, 3): True})
>>> d = C()
>>> assert d.(2, 3) is True
  File "<stdin>", line 1
  d.(2, 3)
    ^
SyntaxError: invalid syntax
>>> getattr(d, (2, 3))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: getattr(): attribute name must be string
>>> 

is not. This gives you access to the entire range of printable characters or other hashable objects for your dictionary keys, which you do not have when accessing an object attribute. This makes possible such magic as a cached object metaclass, like the recipe from the Python Cookbook (Ch. 9).

Wherein I Editorialize

I prefer the aesthetics of spam.eggs over spam['eggs'] (I think it looks cleaner), and I really started craving this functionality when I met the namedtuple. But the convenience of being able to do the following trumps it.

>>> KEYS = 'spam eggs ham'
>>> VALS = [1, 2, 3]
>>> d = {k: v for k, v in zip(KEYS.split(' '), VALS)}
>>> assert d == {'spam': 1, 'eggs': 2, 'ham': 3}
>>>

This is a simple example, but I frequently find myself using dicts in different situations than I'd use obj.key notation (i.e., when I need to read prefs in from an XML file). In other cases, where I'm tempted to instantiate a dynamic class and slap some attributes on it for aesthetic reasons, I continue to use a dict for consistency in order to enhance readability.

I'm sure the OP has long-since resolved this to his satisfaction, but if he still wants this functionality, then I suggest he download one of the packages from pypi that provides it:

• Bunch is the one I'm more familiar with. Subclass of dict, so you have all that functionality.
• AttrDict also looks like it's also pretty good, but I'm not as familiar with it and haven't looked through the source in as much detail as I have Bunch.
• Addict Is actively maintained and provides attr-like access and more.
• As noted in the comments by Rotareti, Bunch has been deprecated, but there is an active fork called Munch.

However, in order to improve readability of his code I strongly recommend that he not mix his notation styles. If he prefers this notation then he should simply instantiate a dynamic object, add his desired attributes to it, and call it a day:

>>> C = type('C', (object,), {})
>>> d = C()
>>> d.spam = 1
>>> d.eggs = 2
>>> d.ham = 3
>>> assert d.__dict__ == {'spam': 1, 'eggs': 2, 'ham': 3}

Wherein I Update, to Answer a Follow-Up Question in the Comments

In the comments (below), Elmo asks:

What if you want to go one deeper? ( referring to type(...) )

While I've never used this use case (again, I tend to use nested dict, for consistency), the following code works:

>>> C = type('C', (object,), {})
>>> d = C()
>>> for x in 'spam eggs ham'.split():
...     setattr(d, x, C())
...     i = 1
...     for y in 'one two three'.split():
...         setattr(getattr(d, x), y, i)
...         i += 1
...
>>> assert d.spam.__dict__ == {'one': 1, 'two': 2, 'three': 3}

use this on:

$('body').on('focus',".datumwaehlen", function(){
    $(this).datepicker({
        minDate: -20
    });
});

If you're not using HTML5 this is a pretty basic JavaScript form validation.

Side note - I'd change the value to 0 on the blur event instead of keyup (as a user I think changing the text as I'm typing would be annoying to no end).

While both of the answers above are good, the procedure for extracting parts of objects is more general.

In many cases, functions return lists, and the individual components can be accessed using str() which will print the components along with their names. You can then access them using the $ operator, i.e. myobject$componentname.

In the case of lm objects, there are a number of predefined methods one can use such as coef(), resid(), summary() etc, but you won't always be so lucky.

<a href="#" onclick="SomeFunction()"  class="SomeClass">sth.</a>

this was my anchor tag. so return false on onClick="" event is not usefull here. I just removed href="#" property and it worked for me just like below

<a onclick="SomeFunction()"  class="SomeClass">sth.</a>

and i needed to add this css.

.SomeClass
{
    cursor: pointer;
}

I had the same problem during request to some server. In my case, setting any value to User-Agent in headers in request options helped me.

const httpRequestOptions = {
    hostname: 'site.address.com',
    headers: {
       'User-Agent': 'Chrome/59.0.3071.115'
    }
};

It's not a general case and depends on server settings.

Yes, you should try to serve valid code if possible.

Most browsers will silently correct this error, but there is a problem with relying on the error handling in the browsers. There is no standard for how to handle incorrect code, so it's up to each browser vendor to try to figure out what to do with each error, and the results may vary.

Some examples where browsers are likely to react differently is if you put elements inside a table but outside the table cells, or if you nest links inside each other.

For your specific example it's not likely to cause any problems, but error correction in the browser might for example cause the browser to change from standards compliant mode into quirks mode, which could make your layout break down completely.

So, you should correct errors like this in the code, if not for anything else so to keep the error list in the validator short, so that you can spot more serious problems.

Use the $locationChangeStart or $locationChangeSuccess events, 3rd parameter:

$scope.$on('$locationChangeStart',function(evt, absNewUrl, absOldUrl) {
   console.log('start', evt, absNewUrl, absOldUrl);
});
$scope.$on('$locationChangeSuccess',function(evt, absNewUrl, absOldUrl) {
   console.log('success', evt, absNewUrl, absOldUrl);
});

Check if any service is listening on port 5037, and kill it. You can use lsof for this:

$ lsof -i :5037
$ kill <PID Process>

Then try

$ adb start-server
* daemon not running. starting it now on port 5037 *
* daemon started successfully *

This solved my problem.

I don't believe search and replace will do it for you (doesn't work for me in Excel 2010 Home). Are you sure you want to put "null" in EVERY cell in the sheet? That is millions of cells, in which case there is no way a search and replace would be able to handle it memory-wise (correct me if I am wrong).

In the case I am right and you don't want millions of "null" cells, then here is a macro. It asks you to select the range then put "null" inside every cell that was blank.

Sub FillWithNull()

Dim cell As range
Dim myRange As range

Set myRange = Application.InputBox("Select the range", Type:=8)
Application.ScreenUpdating = False

For Each cell In myRange
    If Len(cell) = 0 Then
        cell.Value = "Null"
    End If
Next

Application.ScreenUpdating = True

End Sub

Little late to the party. But I thought this is more helpful for who would like to learn (or have clarity) on developing Angular JS Custom Services using factory, service and provider methodologies.

I came across this video which explains clearly about factory, service and provider methodologies for developing AngularJS Custom Services:

https://www.youtube.com/watch?v=oUXku28ex-M

Source Code: http://www.techcbt.com/Post/353/Angular-JS-basics/how-to-develop-angularjs-custom-service

Code posted here is copied straight from the above source, to benefit readers.

The code for "factory" based custom service is as follows (which goes with both sync and async versions along with calling http service):

var app = angular.module("app", []);_x000D_
app.controller('emp', ['$scope', 'calcFactory',_x000D_
  function($scope, calcFactory) {_x000D_
    $scope.a = 10;_x000D_
    $scope.b = 20;_x000D_
_x000D_
    $scope.doSum = function() {_x000D_
      //$scope.sum = calcFactory.getSum($scope.a, $scope.b); //synchronous_x000D_
      calcFactory.getSum($scope.a, $scope.b, function(r) { //aynchronous_x000D_
        $scope.sum = r;_x000D_
      });_x000D_
    };_x000D_
_x000D_
  }_x000D_
]);_x000D_
_x000D_
app.factory('calcFactory', ['$http', '$log',_x000D_
  function($http, $log) {_x000D_
    $log.log("instantiating calcFactory..");_x000D_
    var oCalcService = {};_x000D_
_x000D_
    //oCalcService.getSum = function(a,b){_x000D_
    // return parseInt(a) + parseInt(b);_x000D_
    //};_x000D_
_x000D_
    //oCalcService.getSum = function(a, b, cb){_x000D_
    // var s = parseInt(a) + parseInt(b);_x000D_
    // cb(s);_x000D_
    //};_x000D_
_x000D_
    oCalcService.getSum = function(a, b, cb) { //using http service_x000D_
_x000D_
      $http({_x000D_
        url: 'http://localhost:4467/Sum?a=' + a + '&b=' + b,_x000D_
        method: 'GET'_x000D_
      }).then(function(resp) {_x000D_
        $log.log(resp.data);_x000D_
        cb(resp.data);_x000D_
      }, function(resp) {_x000D_
        $log.error("ERROR occurred");_x000D_
      });_x000D_
    };_x000D_
_x000D_
    return oCalcService;_x000D_
  }_x000D_
]);

The code for "service" methodology for Custom Services (this is pretty similar to 'factory', but different from syntax point of view):

var app = angular.module("app", []);_x000D_
app.controller('emp', ['$scope', 'calcService', function($scope, calcService){_x000D_
 $scope.a = 10;_x000D_
 $scope.b = 20;_x000D_
_x000D_
 $scope.doSum = function(){_x000D_
  //$scope.sum = calcService.getSum($scope.a, $scope.b);_x000D_
  _x000D_
  calcService.getSum($scope.a, $scope.b, function(r){_x000D_
   $scope.sum = r;_x000D_
  });  _x000D_
 };_x000D_
_x000D_
}]);_x000D_
_x000D_
app.service('calcService', ['$http', '$log', function($http, $log){_x000D_
 $log.log("instantiating calcService..");_x000D_
 _x000D_
 //this.getSum = function(a,b){_x000D_
 // return parseInt(a) + parseInt(b);_x000D_
 //};_x000D_
_x000D_
 //this.getSum = function(a, b, cb){_x000D_
 // var s = parseInt(a) + parseInt(b);_x000D_
 // cb(s);_x000D_
 //};_x000D_
_x000D_
 this.getSum = function(a, b, cb){_x000D_
  $http({_x000D_
   url: 'http://localhost:4467/Sum?a=' + a + '&b=' + b,_x000D_
   method: 'GET'_x000D_
  }).then(function(resp){_x000D_
   $log.log(resp.data);_x000D_
   cb(resp.data);_x000D_
  },function(resp){_x000D_
   $log.error("ERROR occurred");_x000D_
  });_x000D_
 };_x000D_
_x000D_
}]);

The code for "provider" methodology for Custom Services (this is necessary, if you would like to develop service which could be configured):

var app = angular.module("app", []);_x000D_
app.controller('emp', ['$scope', 'calcService', function($scope, calcService){_x000D_
 $scope.a = 10;_x000D_
 $scope.b = 20;_x000D_
_x000D_
 $scope.doSum = function(){_x000D_
  //$scope.sum = calcService.getSum($scope.a, $scope.b);_x000D_
  _x000D_
  calcService.getSum($scope.a, $scope.b, function(r){_x000D_
   $scope.sum = r;_x000D_
  });  _x000D_
 };_x000D_
_x000D_
}]);_x000D_
_x000D_
app.provider('calcService', function(){_x000D_
_x000D_
 var baseUrl = '';_x000D_
_x000D_
 this.config = function(url){_x000D_
  baseUrl = url;_x000D_
 };_x000D_
_x000D_
 this.$get = ['$log', '$http', function($log, $http){_x000D_
  $log.log("instantiating calcService...")_x000D_
  var oCalcService = {};_x000D_
_x000D_
  //oCalcService.getSum = function(a,b){_x000D_
  // return parseInt(a) + parseInt(b);_x000D_
  //};_x000D_
_x000D_
  //oCalcService.getSum = function(a, b, cb){_x000D_
  // var s = parseInt(a) + parseInt(b);_x000D_
  // cb(s); _x000D_
  //};_x000D_
_x000D_
  oCalcService.getSum = function(a, b, cb){_x000D_
_x000D_
   $http({_x000D_
    url: baseUrl + '/Sum?a=' + a + '&b=' + b,_x000D_
    method: 'GET'_x000D_
   }).then(function(resp){_x000D_
    $log.log(resp.data);_x000D_
    cb(resp.data);_x000D_
   },function(resp){_x000D_
    $log.error("ERROR occurred");_x000D_
   });_x000D_
  };  _x000D_
_x000D_
  return oCalcService;_x000D_
 }];_x000D_
_x000D_
});_x000D_
_x000D_
app.config(['calcServiceProvider', function(calcServiceProvider){_x000D_
 calcServiceProvider.config("http://localhost:4467");_x000D_
}]);

Finally the UI which works with any of the above services:

Best solution for cropping an UIImage in Swift, in term of precision, pixels scaling ...:

private func squareCropImageToSideLength(let sourceImage: UIImage,
    let sideLength: CGFloat) -> UIImage {
        // input size comes from image
        let inputSize: CGSize = sourceImage.size

        // round up side length to avoid fractional output size
        let sideLength: CGFloat = ceil(sideLength)

        // output size has sideLength for both dimensions
        let outputSize: CGSize = CGSizeMake(sideLength, sideLength)

        // calculate scale so that smaller dimension fits sideLength
        let scale: CGFloat = max(sideLength / inputSize.width,
            sideLength / inputSize.height)

        // scaling the image with this scale results in this output size
        let scaledInputSize: CGSize = CGSizeMake(inputSize.width * scale,
            inputSize.height * scale)

        // determine point in center of "canvas"
        let center: CGPoint = CGPointMake(outputSize.width/2.0,
            outputSize.height/2.0)

        // calculate drawing rect relative to output Size
        let outputRect: CGRect = CGRectMake(center.x - scaledInputSize.width/2.0,
            center.y - scaledInputSize.height/2.0,
            scaledInputSize.width,
            scaledInputSize.height)

        // begin a new bitmap context, scale 0 takes display scale
        UIGraphicsBeginImageContextWithOptions(outputSize, true, 0)

        // optional: set the interpolation quality.
        // For this you need to grab the underlying CGContext
        let ctx: CGContextRef = UIGraphicsGetCurrentContext()
        CGContextSetInterpolationQuality(ctx, kCGInterpolationHigh)

        // draw the source image into the calculated rect
        sourceImage.drawInRect(outputRect)

        // create new image from bitmap context
        let outImage: UIImage = UIGraphicsGetImageFromCurrentImageContext()

        // clean up
        UIGraphicsEndImageContext()

        // pass back new image
        return outImage
}

Instructions used to call this function:

let image: UIImage = UIImage(named: "Image.jpg")!
let squareImage: UIImage = self.squareCropImageToSideLength(image, sideLength: 320)
self.myUIImageView.image = squareImage

Note: the initial source code inspiration written in Objective-C has been found on "Cocoanetics" blog.

For your specific case, just use the reduce method of Arrays:

var sumArray = function() {
    // Use one adding function rather than create a new one each
    // time sumArray is called
    function add(a, b) {
        return a + b;
    }

    return function(arr) {
        return arr.reduce(add);
    };
}();

alert( sumArray([2, 3, 4]) );

I think its works for everyone

The reason it is not working is because you are adding an item to the list and then overriding the whole list with a new DataSource which will clear and re-populate your list, losing the first manually added item.

So, you need to do this in reverse like this:

Status status = new Status();
DropDownList1.DataSource = status.getData();
DropDownList1.DataValueField = "ID";
DropDownList1.DataTextField = "Description";
DropDownList1.DataBind();

// Then add your first item
DropDownList1.Items.Insert(0, "Select");

JSONArray has a constructor which takes a String source (presumed to be an array).

So something like this

JSONArray array = new JSONArray(yourJSONArrayAsString);

if you're talking floating point values, you have to be very careful due to the nature of the format.

the best way that i know of doing this is deciding on some epsilon value, say, 0.000001f, and then doing something like this:

boolean nearZero(float f)
{
    return ((-episilon < f) && (f <epsilon)); 
}

then

if(nearZero(z-(int)z))
{ 
    //do stuff
}

essentially you're checking to see if z and the integer case of z have the same magnitude within some tolerance. This is necessary because floating are inherently imprecise.

NOTE, HOWEVER: this will probably break if your floats have magnitude greater than Integer.MAX_VALUE (2147483647), and you should be aware that it is by necessity impossible to check for integral-ness on floats above that value.

SQLFiddle will let you test out your queries, while it doesn't explicitly correct syntax etc. per se it does let you play around with the script and will definitely let you know if things are working or not.

Yes, if you have URL wrappers disabled you should use sockets or, even better, the cURL library.

If it's part of your site then refer to it with the file system path, not the web URL. /var/www/..., rather than http://domain.tld/....

your id attribute is not set. this MAY be due to the fact that the DB field is not set to auto increment? what DB are you using? MySQL? is your field set to AUTO INCREMENT?

I wanted to share the root cause for my issue. I was using High DPI in Windows and this caused JNLP to not launch. I had to turn off High DPI for this to work. Hope this helps.

Here's a solution to the general case that doesn't involve needing to know the length of the array ahead of time, using collect, or using udfs. Unfortunately this only works for spark version 2.1 and above, because it requires the posexplode function.

Suppose you had the following DataFrame:

df = spark.createDataFrame(
    [
        [1, 'A, B, C, D'], 
        [2, 'E, F, G'], 
        [3, 'H, I'], 
        [4, 'J']
    ]
    , ["num", "letters"]
)
df.show()
#+---+----------+
#|num|   letters|
#+---+----------+
#|  1|A, B, C, D|
#|  2|   E, F, G|
#|  3|      H, I|
#|  4|         J|
#+---+----------+

Split the letters column and then use posexplode to explode the resultant array along with the position in the array. Next use pyspark.sql.functions.expr to grab the element at index pos in this array.

import pyspark.sql.functions as f

df.select(
        "num",
        f.split("letters", ", ").alias("letters"),
        f.posexplode(f.split("letters", ", ")).alias("pos", "val")
    )\
    .show()
#+---+------------+---+---+
#|num|     letters|pos|val|
#+---+------------+---+---+
#|  1|[A, B, C, D]|  0|  A|
#|  1|[A, B, C, D]|  1|  B|
#|  1|[A, B, C, D]|  2|  C|
#|  1|[A, B, C, D]|  3|  D|
#|  2|   [E, F, G]|  0|  E|
#|  2|   [E, F, G]|  1|  F|
#|  2|   [E, F, G]|  2|  G|
#|  3|      [H, I]|  0|  H|
#|  3|      [H, I]|  1|  I|
#|  4|         [J]|  0|  J|
#+---+------------+---+---+

Now we create two new columns from this result. First one is the name of our new column, which will be a concatenation of letter and the index in the array. The second column will be the value at the corresponding index in the array. We get the latter by exploiting the functionality of pyspark.sql.functions.expr which allows us use column values as parameters.

df.select(
        "num",
        f.split("letters", ", ").alias("letters"),
        f.posexplode(f.split("letters", ", ")).alias("pos", "val")
    )\
    .drop("val")\
    .select(
        "num",
        f.concat(f.lit("letter"),f.col("pos").cast("string")).alias("name"),
        f.expr("letters[pos]").alias("val")
    )\
    .show()
#+---+-------+---+
#|num|   name|val|
#+---+-------+---+
#|  1|letter0|  A|
#|  1|letter1|  B|
#|  1|letter2|  C|
#|  1|letter3|  D|
#|  2|letter0|  E|
#|  2|letter1|  F|
#|  2|letter2|  G|
#|  3|letter0|  H|
#|  3|letter1|  I|
#|  4|letter0|  J|
#+---+-------+---+

Now we can just groupBy the num and pivot the DataFrame. Putting that all together, we get:

df.select(
        "num",
        f.split("letters", ", ").alias("letters"),
        f.posexplode(f.split("letters", ", ")).alias("pos", "val")
    )\
    .drop("val")\
    .select(
        "num",
        f.concat(f.lit("letter"),f.col("pos").cast("string")).alias("name"),
        f.expr("letters[pos]").alias("val")
    )\
    .groupBy("num").pivot("name").agg(f.first("val"))\
    .show()
#+---+-------+-------+-------+-------+
#|num|letter0|letter1|letter2|letter3|
#+---+-------+-------+-------+-------+
#|  1|      A|      B|      C|      D|
#|  3|      H|      I|   null|   null|
#|  2|      E|      F|      G|   null|
#|  4|      J|   null|   null|   null|
#+---+-------+-------+-------+-------+

Cross browser solution for printing pdf from base64 string:

• Chrome: print window is opened
• FF: new tab with pdf is opened
• IE11: open/save prompt is opened

.

const blobPdfFromBase64String = base64String => {
   const byteArray = Uint8Array.from(
     atob(base64String)
       .split('')
       .map(char => char.charCodeAt(0))
   );
  return new Blob([byteArray], { type: 'application/pdf' });
};

const isIE11 = !!(window.navigator && window.navigator.msSaveOrOpenBlob); // or however you want to check it

const printPDF = blob => {
   try {
     isIE11
       ? window.navigator.msSaveOrOpenBlob(blob, 'documents.pdf')
       : printJS(URL.createObjectURL(blob)); // http://printjs.crabbly.com/
   } catch (e) {
     throw PDFError;
   }
};

printPDF(blobPdfFromBase64String(base64String))

BONUS - Opening blob file in new tab for IE11

If you're able to do some preprocessing of the base64 string on the server you could expose it under some url and use the link in printJS :)

In C, a string, as you know, is a character pointer (char *). If you want to swap two strings, you're swapping two char pointers, i.e. just two addresses. In order to do any swap in a function, you need to give it the addresses of the two things you're swapping. So in the case of swapping two pointers, you need a pointer to a pointer. Much like to swap an int, you just need a pointer to an int.

The reason your last code snippet doesn't work is because you're expecting it to swap two char pointers -- it's actually written to swap two characters!

Edit: In your example above, you're trying to swap two int pointers incorrectly, as R. Martinho Fernandes points out. That will swap the two ints, if you had:

int a, b;
intSwap(&a, &b);

You need to insert the new row and then copy from the source row to the newly inserted row. Excel allows you to paste special just formulas. So in Excel:

• Insert the new row
• Copy the source row
• Select the newly created target row, right click and paste special
• Paste as formulas

VBA if required with Rows("1:1") being source and Rows("2:2") being target:

Rows("2:2").Insert Shift:=xlDown, CopyOrigin:=xlFormatFromLeftOrAbove
Rows("2:2").Clear

Rows("1:1").Copy
Rows("2:2").PasteSpecial Paste:=xlPasteFormulas, Operation:=xlNone

The "manual bootstrap" case can gain access to Angular services by manually creating an injector before bootstrap. This initial injector will stand alone (not be attached to any elements) and include only a subset of the modules that are loaded. If all you need is core Angular services, it's sufficient to just load ng, like this:

angular.element(document).ready(
    function() {
        var initInjector = angular.injector(['ng']);
        var $http = initInjector.get('$http');
        $http.get('/config.json').then(
            function (response) {
               var config = response.data;
               // Add additional services/constants/variables to your app,
               // and then finally bootstrap it:
               angular.bootstrap(document, ['myApp']);
            }
        );
    }
);

You can, for example, use the module.constant mechanism to make data available to your app:

myApp.constant('myAppConfig', data);

This myAppConfig can now be injected just like any other service, and in particular it's available during the configuration phase:

myApp.config(
    function (myAppConfig, someService) {
        someService.config(myAppConfig.someServiceConfig);
    }
);

or, for a smaller app, you could just inject the global config directly into your service, at the expense of spreading knowledge about the configuration format throughout the application.

Of course, since the async operations here will block the bootstrap of the application, and thus block the compilation/linking of the template, it's wise to use the ng-cloak directive to prevent the unparsed template from showing up during the work. You could also provide some sort of loading indication in the DOM , by providing some HTML that gets shown only until AngularJS initializes:

<div ng-if="initialLoad">
    <!-- initialLoad never gets set, so this div vanishes as soon as Angular is done compiling -->
    <p>Loading the app.....</p>
</div>
<div ng-cloak>
    <!-- ng-cloak attribute is removed once the app is done bootstrapping -->
    <p>Done loading the app!</p>
</div>

I created a complete, working example of this approach on Plunker, loading the configuration from a static JSON file as an example.

1. Right click on Project Name.
2. Select Properties and click.
3. Then, select Debugging and provide your enough argument into Command Arguments box.

Note:

• Also, check Configuration type and Platform.

After that, Click Apply and OK.

if you're in a situation like me where procedures and functions are prohibited, and your sql user does not have permissions for insert, therefore insert not allowed, also "set/declare temporary variables like @c is not allowed", but you want to generate a list of dates in a specific period, say current year to do some aggregation, use this

select * from 
(select adddate('1970-01-01',t4*10000 + t3*1000 + t2*100 + t1*10 + t0) gen_date from
 (select 0 t0 union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t0,
 (select 0 t1 union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t1,
 (select 0 t2 union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t2,
 (select 0 t3 union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t3,
 (select 0 t4 union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) t4) v
where gen_date between '2017-01-01' and '2017-12-31'

How about CAST(2229.999 AS DECIMAL(6,2)) to get a decimal with 2 decimal places

This is what I did:

1. Change project and solution name in Visual Studio
2. Close the project and open the folder containing the project (The Visual studio solution name is already changed).
3. Change the old project folder names to the new project name
4. Open the .sln file and the change the project folder names manually from old to new folder names.
5. Save the .sln file in the text editor
6. Open the project again with Visual Studio and the solution is ready to modify

Did find the answer on my own. My problem was, that i use two temporary tables for a join and create the second one out of the first one. But the Index was not copied during creation...

CREATE TEMPORARY TABLE tmpLivecheck (tmpid INTEGER NOT NULL AUTO_INCREMENT, PRIMARY    
KEY(tmpid), INDEX(tmpid))
SELECT * FROM tblLivecheck_copy WHERE tblLivecheck_copy.devId = did;

CREATE TEMPORARY TABLE tmpLiveCheck2 (tmpid INTEGER NOT NULL, PRIMARY KEY(tmpid), 
INDEX(tmpid))  
SELECT * FROM tmpLivecheck;

... solved my problem.

Greetings...

Subversion implicitly has the remote repository associated with it at all times. Git, on the other hand, allows many "remotes", each of which represents a single remote place you can push to or pull from.

You need to add a remote for the GitHub repository to your local repository, then use git push ${remote} or git pull ${remote} to push and pull respectively - or the GUI equivalents.

Pro Git discusses remotes here: http://git-scm.com/book/ch2-5.html

The GitHub help also discusses them in a more "task-focused" way here: http://help.github.com/remotes/

Once you have associated the two you will be able to push or pull branches.

drop table if exists foo;
create table foo
(
id int unsigned not null auto_increment primary key,
val smallint unsigned not null default 0
)
engine=innodb;

drop procedure if exists load_foo_test_data;

delimiter #
create procedure load_foo_test_data()
begin

declare v_max int unsigned default 1000;
declare v_counter int unsigned default 0;

  truncate table foo;
  start transaction;
  while v_counter < v_max do
    insert into foo (val) values ( floor(0 + (rand() * 65535)) );
    set v_counter=v_counter+1;
  end while;
  commit;
end #

delimiter ;

call load_foo_test_data();

select * from foo order by id;

I have a solution below and its works for me:

app.controller('LoginController', ['$http', '$scope', function ($scope, $http) {
$scope.login = function (credentials) {
$http({
        method: 'jsonp',
        url: 'http://mywebservice',
        params: {
            format: 'jsonp',
            callback: 'JSON_CALLBACK'
        }
    }).then(function (response) {
        alert(response.data);
    });
  }
}]);

in 'http://mywebservice' there must be need a callback parameter which return JSON_CALLBACK with data.
There is a sample example below which works perfect

$scope.url = "https://angularjs.org/greet.php";
    $http({
        method: 'jsonp',
        url: $scope.url,
        params: {
            format: 'jsonp',
            name: 'Super Hero',
            callback: 'JSON_CALLBACK'
        }
    }).then(function (response) {
        alert(response.data);
    });

example output:

{"name":"Super Hero","salutation":"Apa khabar","greeting":"Apa khabar Super Hero!"}

Although the earlier answers are OK, here's my contribution.

//returns the size of a character array using a pointer to the first element of the character array
int size(char *ptr)
{
    //variable used to access the subsequent array elements.
    int offset = 0;
    //variable that counts the number of elements in your array
    int count = 0;

    //While loop that tests whether the end of the array has been reached
    while (*(ptr + offset) != '\0')
    {
        //increment the count variable
        ++count;
        //advance to the next element of the array
        ++offset;
    }
    //return the size of the array
    return count;
}

In your main function, you call the size function by passing the address of the first element of your array.

For example:

char myArray[] = {'h', 'e', 'l', 'l', 'o'};
printf("The size of my character array is: %d\n", size(&myArray[0]));

In Java, single quotes can only take one character, with escape if necessary. You need to use full quotation marks as follows for strings:

y = "hello";

You also used

System.out.println(g);

which I assume should be

System.out.println(y);

Note: When making char values (you'll likely use them later) you need single quotes. For example:

char foo='m';

The prevailing thought is that the NOT operator may only be used to remove results from a query - not just exclude things out of the entire dataset. I happen to like the syntax you suggested mausch - thanks!

You can't create tags with Dockerfiles but you can create multiple tags on your images via the command line.

Use this to list your image ids:

$ docker images

Then tag away:

$ docker tag 9f676bd305a4 ubuntu:13.10
$ docker tag 9f676bd305a4 ubuntu:saucy
$ docker tag eb601b8965b8 ubuntu:raring

I found this brilliant solution here, it uses the simple logic NAN!=NAN. https://www.codespeedy.com/check-if-a-given-string-is-nan-in-python/

Using above example you can simply do the following. This should work on different type of objects as it simply utilize the fact that NAN is not equal to NAN.

 import numpy as np
 s = pd.Series(['apple', np.nan, 'banana'])
 s.apply(lambda x: x!=x)
 out[252]
 0    False
 1     True
 2    False
 dtype: bool

It's true that some databases recognize the OUTER keyword. Some do not. Where it is recognized, it is usually an optional keyword. Almost always, FULL JOIN and FULL OUTER JOIN do exactly the same thing. (I can't think of an example where they do not. Can anyone else think of one?)

This may leave you wondering, "Why would it even be a keyword if it has no meaning?" The answer boils down to programming style.

In the old days, programmers strived to make their code as compact as possible. Every character meant longer processing time. We used 1, 2, and 3 letter variables. We used 2 digit years. We eliminated all unnecessary white space. Some people still program that way. It's not about processing time anymore. It's more about fast coding.

Modern programmers are learning to use more descriptive variables and put more remarks and documentation into their code. Using extra words like OUTER make sure that other people who read the code will have an easier time understanding it. There will be less ambiguity. This style is much more readable and kinder to the people in the future who will have to maintain that code.

Why don't you simply move the code you have in the ApiController calls - DocumentsController to a class that you can call from both your HomeController and DocumentController. Pull this out into a class you call from both controllers. This stuff in your question:

// All code to find the files are here and is working perfectly...

It doesn't make sense to call a API Controller from another controller on the same website.

This will also simplify the code when you come back to it in the future you will have one common class for finding the files and doing that logic there...

It's indeed almost a duplicate. I guess the regex you're looking for is

Here is some interesting information about SET / SELECT

• SET is the ANSI standard for variable assignment, SELECT is not.
• SET can only assign one variable at a time, SELECT can make multiple assignments at once.
• If assigning from a query, SET can only assign a scalar value. If the query returns multiple values/rows then SET will raise an error. SELECT will assign one of the values to the variable and hide the fact that multiple values were returned (so you'd likely never know why something was going wrong elsewhere - have fun troubleshooting that one)
• When assigning from a query if there is no value returned then SET will assign NULL, where SELECT will not make the assignment at all (so the variable will not be changed from it's previous value)
• As far as speed differences - there are no direct differences between SET and SELECT. However SELECT's ability to make multiple assignments in one shot does give it a slight speed advantage over SET.

I use the ArrayDebugView add-in for Visual Studio (http://arraydebugview.sourceforge.net/).

It seems to be a long dead project (but one I'm looking at continuing myself) but the add-in still works beautifully for me in VS2010 for both C++ and C#.

It has a few quirks (tab order, modal dialog, no close button) but the ability to plot the contents of an array in a graph more than make up for it.

Edit July 2014: I have finally built a new Visual Studio extension to replace ArrayebugView's functionality. It is available on the VIsual Studio Gallery, search for ArrayPlotter or go to http://visualstudiogallery.msdn.microsoft.com/2fde2c3c-5b83-4d2a-a71e-5fdd83ce6b96?SRC=Home

There is a jquery plugin for this. It scrolls document to a specific element, so that it would be perfectly in the middle of viewport. It also supports animation easings so that the scroll effect would look super smooth. Check out AnimatedScroll.js.

If you just need the name of the device here is a little hack which i wrote in bash. To run it in python you need the following snippet. Just replace $1 and $2 with Bus number and Device number eg 001 or 002.

import os
os.system("lsusb | grep \"Bus $1 Device $2\" | sed 's/\// /' | awk '{for(i=7;i<=NF;++i)print $i}'")

Alternately you can save it as a bash script and run it from there too. Just save it as a bash script like foo.sh make it executable.

#!/bin/bash
myvar=$(lsusb | grep "Bus $1 Device $2" | sed 's/\// /' | awk '{for(i=7;i<=NF;++i)print $i}')
echo $myvar

Then call it in python script as

import os
os.system('foo.sh')

One of the simplest way: use Link as follows:

import { Link } from 'react-router-dom';

<Link to={`your-path`} activeClassName="current">{your-link-name}</Link>

If we want to cover the whole div section as link:

 <div>
     <Card as={Link} to={'path-name'}>
         .... 
           card content here
         ....
     </Card>
 </div>

I have used both JXL (now "JExcel") and Apache POI. At first I used JXL, but now I use Apache POI.

First, here are the things where both APIs have the same end functionality:

• Both are free
• Cell styling: alignment, backgrounds (colors and patterns), borders (types and colors), font support (font names, colors, size, bold, italic, strikeout, underline)
• Formulas
• Hyperlinks
• Merged cell regions
• Size of rows and columns
• Data formatting: Numbers and Dates
• Text wrapping within cells
• Freeze Panes
• Header/Footer support
• Read/Write existing and new spreadsheets
• Both attempt to keep existing objects in spreadsheets they read in intact as far as possible.

However, there are many differences:

• Perhaps the most significant difference is that Java JXL does not support the Excel 2007+ ".xlsx" format; it only supports the old BIFF (binary) ".xls" format. Apache POI supports both with a common design.
• Additionally, the Java portion of the JXL API was last updated in 2009 (3 years, 4 months ago as I write this), although it looks like there is a C# API. Apache POI is actively maintained.
• JXL doesn't support Conditional Formatting, Apache POI does, although this is not that significant, because you can conditionally format cells with your own code.
• JXL doesn't support rich text formatting, i.e. different formatting within a text string; Apache POI does support it.
• JXL only supports certain text rotations: horizontal/vertical, +/- 45 degrees, and stacked; Apache POI supports any integer number of degrees plus stacked.
• JXL doesn't support drawing shapes; Apache POI does.
• JXL supports most Page Setup settings such as Landscape/Portrait, Margins, Paper size, and Zoom. Apache POI supports all of that plus Repeating Rows and Columns.
• JXL doesn't support Split Panes; Apache POI does.
• JXL doesn't support Chart creation or manipulation; that support isn't there yet in Apache POI, but an API is slowly starting to form.
• Apache POI has a more extensive set of documentation and examples available than JXL.

Additionally, POI contains not just the main "usermodel" API, but also an event-based API if all you want to do is read the spreadsheet content.

In conclusion, because of the better documentation, more features, active development, and Excel 2007+ format support, I use Apache POI.

Make sure that you don't declare it as a integer, float, string or boolean before. http://php.net/manual/en/function.is-scalar.php

Hope this's not too late to help!!!

Java is type-safe, meaning that only Objects are able to create instances.

In my case I cannot pass parameters to the createContents method. My solution is using extends unlike the answer below.

private static class SomeContainer<E extends Object> {
    E e;
    E createContents() throws Exception{
        return (E) e.getClass().getDeclaredConstructor().newInstance();
    }
}

This is my example case in which I can't pass parameters.

public class SomeContainer<E extends Object> {
    E object;

    void resetObject throws Exception{
        object = (E) object.getClass().getDeclaredConstructor().newInstance();
    }
}

Using reflection create run time error, if you extends your generic class with none object type. To extends your generic type to object convert this error to compile time error.

With C++17 the standard way to copy a file will be including the <filesystem> header and using:

bool copy_file( const std::filesystem::path& from,
                const std::filesystem::path& to);

bool copy_file( const std::filesystem::path& from,
                const std::filesystem::path& to,
                std::filesystem::copy_options options);

The first form is equivalent to the second one with copy_options::none used as options (see also copy_file).

The filesystem library was originally developed as boost.filesystem and finally merged to ISO C++ as of C++17.

For me after changing information in sql database nothing could refresh list view( to be specific expandable list view) so if notifyDataSetChanged() doesn't help, you can try to clear your list first and add it again after that call notifyDataSetChanged(). For example

private List<List<SomeNewArray>> arrayList;
List<SomeNewArray> array1= getArrayList(...);
List<SomeNewArray> array2= getArrayList(...);
arrayList.clear();
arrayList.add(array1);
arrayList.add(array2);
notifyDataSetChanged();

Hope it makes sense for you.

I think the only way of doing this in SQL-Server 2008R2 is to use a correlated subquery, or an outer apply:

SELECT  datekey,
        COALESCE(RunningTotal, 0) AS RunningTotal,
        COALESCE(RunningCount, 0) AS RunningCount,
        COALESCE(RunningDistinctCount, 0) AS RunningDistinctCount
FROM    document
        OUTER APPLY
        (   SELECT  SUM(Amount) AS RunningTotal,
                    COUNT(1) AS RunningCount,
                    COUNT(DISTINCT d2.dateKey) AS RunningDistinctCount
            FROM    Document d2
            WHERE   d2.DateKey <= document.DateKey
        ) rt;

This can be done in SQL-Server 2012 using the syntax you have suggested:

SELECT  datekey,
        SUM(Amount) OVER(ORDER BY DateKey) AS RunningTotal
FROM    document

However, use of DISTINCT is still not allowed, so if DISTINCT is required and/or if upgrading isn't an option then I think OUTER APPLY is your best option

you try this:

<input type="submit" style="font-face: 'Comic Sans MS'; font-size: larger; color: teal; background-color: #FFFFC0; border: 3pt ridge lightgrey" value=" Send Me! ">

It's not generally correct that you can "remove an item from a database" with both methods. To be precise it is like so:

• ObjectContext.DeleteObject(entity) marks the entity as Deleted in the context. (It's EntityState is Deleted after that.) If you call SaveChanges afterwards EF sends a SQL DELETE statement to the database. If no referential constraints in the database are violated the entity will be deleted, otherwise an exception is thrown.

• EntityCollection.Remove(childEntity) marks the relationship between parent and childEntity as Deleted. If the childEntity itself is deleted from the database and what exactly happens when you call SaveChanges depends on the kind of relationship between the two:

  • If the relationship is optional, i.e. the foreign key that refers from the child to the parent in the database allows NULL values, this foreign will be set to null and if you call SaveChanges this NULL value for the childEntity will be written to the database (i.e. the relationship between the two is removed). This happens with a SQL UPDATE statement. No DELETE statement occurs.

  • If the relationship is required (the FK doesn't allow NULL values) and the relationship is not identifying (which means that the foreign key is not part of the child's (composite) primary key) you have to either add the child to another parent or you have to explicitly delete the child (with DeleteObject then). If you don't do any of these a referential constraint is violated and EF will throw an exception when you call SaveChanges - the infamous "The relationship could not be changed because one or more of the foreign-key properties is non-nullable" exception or similar.

  • If the relationship is identifying (it's necessarily required then because any part of the primary key cannot be NULL) EF will mark the childEntity as Deleted as well. If you call SaveChanges a SQL DELETE statement will be sent to the database. If no other referential constraints in the database are violated the entity will be deleted, otherwise an exception is thrown.

I am actually a bit confused about the Remarks section on the MSDN page you have linked because it says: "If the relationship has a referential integrity constraint, calling the Remove method on a dependent object marks both the relationship and the dependent object for deletion.". This seems unprecise or even wrong to me because all three cases above have a "referential integrity constraint" but only in the last case the child is in fact deleted. (Unless they mean with "dependent object" an object that participates in an identifying relationship which would be an unusual terminology though.)

Switch to the branch from which you created the pull request:

$ git checkout pull-request-branch

Overwrite the modified file(s) with the file in another branch, let's consider it's master:

git checkout origin/master -- src/main/java/HelloWorld.java

Commit and push it to the remote:

git commit -m "Removed a modified file from pull request"
git push origin pull-request-branch

EDIT:

Ok I found why the int.ToString() in LINQtoEF fails, please read this post: Problem with converting int to string in Linq to entities

This works on my side :

        List<string> materialTypes = (from u in result.Users
                                      select u.LastName)
                       .Union(from u in result.Users
                               select SqlFunctions.StringConvert((double) u.UserId)).ToList();

On yours it should be like this:

    IList<String> materialTypes = ((from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select tom.Name)
                                       .Union(from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select SqlFunctions.StringConvert((double)tom.ID))).ToList();

Thanks, i've learnt something today :)

Are you sure it's not a Table-Valued Function?

The reason I ask:

CREATE FUNCTION dbo.chk_mgr(@mgr VARCHAR(50)) 
RETURNS @mgr_table TABLE (mgr_name VARCHAR(50))
AS
BEGIN 
  INSERT @mgr_table (mgr_name) VALUES ('pointy haired boss') 
  RETURN
END 
GO

SELECT dbo.chk_mgr('asdf')
GO

Result:

Msg 4121, Level 16, State 1, Line 1
Cannot find either column "dbo" or the user-defined function 
or aggregate "dbo.chk_mgr", or the name is ambiguous.

However...

SELECT * FROM dbo.chk_mgr('asdf') 

mgr_name

In my case decorating the parameter class with the [JsonObject(MemberSerialization.OptOut)] attribute from Newtonsoft did the trick.

For example:

[HttpPost]
[Route("MyRoute")]
public IHttpActionResult DoWork(MyClass args)
{
   ...
}

[JsonObject(MemberSerialization.OptOut)]
public Class MyClass
{
    ...
}

In fact, the solution is very easy...

Original:

    <form action="product.php" method="get" name="frmProduct" id="frmProduct"
enctype="multipart/form-data">
    <input onclick="submitAction()" id="submit_value" type="button" 
    name="submit_value" value="">
</form>
<script type="text/javascript">
    function submitAction()
    {
        document.frmProduct.submit();
    }
</script>

Solution:

    <form action="product.php" method="get" name="frmProduct" id="frmProduct" 
enctype="multipart/form-data">
</form>

<!-- Place the button here -->
<input onclick="submitAction()" id="submit_value" type="button" 
    name="submit_value" value="">

<script type="text/javascript">
    function submitAction()
    {
        document.frmProduct.submit();
    }
</script>

If you don't mind potentially stale data, you can access the same statistics used by the query optimizer.

Something like:

SELECT relname, n_tup_ins - n_tup_del as rowcount FROM pg_stat_all_tables;

Just in case somebody ist still coming along this question:

There is a body query object in any request. You do not need to parse it yourself.

E.g. if you want to send an accessToken from a client with GET, you could do it like this:

const request = require('superagent');_x000D_
_x000D_
request.get(`http://localhost:3000/download?accessToken=${accessToken}`).end((err, res) => {_x000D_
  if (err) throw new Error(err);_x000D_
  console.log(res);_x000D_
});

The server request object then looks like {request: { ... query: { accessToken: abcfed } ... } }

If you use php5.6 then execute this:

sudo apt-get install php5.6-zip

You can use the get() on each dict. Make sure that you have added the None check for each access.

I know this is really a really old question, but I was trying to do the same thing and I stumbled upon a new formula in excel called "TEXTJOIN".

For the question, the following formula solves the problem

=TEXTJOIN("",TRUE,(a1:a4))

The signature of "TEXTJOIN" is explained as TEXTJOIN(delimiter,ignore_empty,text1,[text2],[text3],...)

I don't know about underline, but for bold and italic there is "bolditalic". There is no mention of underline here: http://developer.android.com/reference/android/widget/TextView.html#attr_android:textStyle

Mind you that to use the mentioned bolditalic you need to, and I quote from that page

Must be one or more (separated by '|') of the following constant values.

so you'd use bold|italic

You could check this question for underline: Can I underline text in an android layout?

The syntaxes

int[]

and

int[X] // Where X is a compile-time positive integer

are exactly the same as

int*

when in a function parameter list (I left out the optional names).

Additionally, an array name decays to a pointer to the first element when passed to a function (and not passed by reference) so both int firstarray[3] and int secondarray[5] decay to int*s.

It also happens that both an array dereference and a pointer dereference with subscript syntax (subscript syntax is x[y]) yield an lvalue to the same element when you use the same index.

These three rules combine to make the code legal and work how you expect; it just passes pointers to the function, along with the length of the arrays which you cannot know after the arrays decay to pointers.

Have you tried using @JsonProperty?

@Entity
public class City {
   @id
   Long id;
   String name;

   @JsonProperty("label")
   public String getName() { return name; }

   public void setName(String name){ this.name = name; }

   @JsonProperty("value")
   public Long getId() { return id; }

   public void setId(Long id){ this.id = id; }
}

For some reasons, Webkit-based browsers don't follow the spec for the dialog box. An almost cross-working example would be close from the below example.

window.addEventListener("beforeunload", function (e) {
  var confirmationMessage = "\o/";

  (e || window.event).returnValue = confirmationMessage; //Gecko + IE
  return confirmationMessage;                            //Webkit, Safari, Chrome
});

This example for handling all browsers.

If you don't want to include any special character, then try this much simple way for checking special characters using RegExp \W Metacharacter.

var iChars = "~`!#$%^&*+=-[]\\\';,/{}|\":<>?";
if(!(iChars.match(/\W/g)) == "") {
    alert ("File name has special characters ~`!#$%^&*+=-[]\\\';,/{}|\":<>? \nThese are not allowed\n");
    return false;
}

In the HKEY_USERS\oneyouwanttoknow\ you can look at \Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders and it will reveal their profile paths. c:\users\whothisis\Desktop, etc.

If you want your form's field clear, you must only add a delay in the onClick event like:

<input name="submit" id="MyButton" type="submit" class="btn-lg" value="ClickMe" onClick="setTimeout('clearform()', 2000 );"

onClick="setTimeout('clearform()', 1500 );" . in 1,5 seconds its clear

document.getElementById("name").value = "";  <<<<<<just correct this
document.getElementById("telephone").value = "";    <<<<<correct this

By clearform(), I mean your clearing-fields function.

I've also found it useful to access object attributes where the attribute names vary by some iterator. For example, I have used the pattern below for a set of time periods: hour, day, month.

$periods=array('hour', 'day', 'month');
foreach ($periods as $period)
{
    $this->{'value_'.$period}=1;
}

This same pattern can also be used to access class methods. Just build up the method name in the same manner, using strings and string variables.

You could easily argue to just use an array for the value storage by period. If this application were PHP only, I would agree. I use this pattern when the class attributes map to fields in a database table. While it is possible to store arrays in a database using serialization, it is inefficient, and pointless if the individual fields must be indexed. I often add an array of the field names, keyed by the iterator, for the best of both worlds.

class timevalues
{
                             // Database table values:
    public $value_hour;      // maps to values.value_hour
    public $value_day;       // maps to values.value_day
    public $value_month;     // maps to values.value_month
    public $values=array();

    public function __construct()
    {
        $this->value_hour=0;
        $this->value_day=0;
        $this->value_month=0;
        $this->values=array(
            'hour'=>$this->value_hour,
            'day'=>$this->value_day,
            'month'=>$this->value_month,
        );
    }
}

You ca set top position in style for display on center, saw that the code:

.ui-dialog{top: 100px !important;}

This style should show dialog box 100px bellow from top.

The connect router has now been removed (https://github.com/senchalabs/connect/issues/262), the author stating that you should use a framework on top of connect (like Express) for routing.

Express currently treats app.get("/foo*") as app.get(/\/foo(.*)/), removing the need for two separate routes. This is in contrast to the previous answer (referring to the now removed connect router) which stated that "* in a path is replaced with .+".

Update: Express now uses the "path-to-regexp" module (since Express 4.0.0) which maintains the same behavior in the version currently referenced. It's unclear to me whether the latest version of that module keeps the behavior, but for now this answer stands.

jsonify prevents you from doing this in Flask 0.10 and lower for security reasons.

To do it anyway, just use json.dumps in the Python standard library.

http://docs.python.org/library/json.html#json.dumps

console.log( 'You are running jQuery version: ' + $.fn.jquery );

In my case, the issue was unrelated to CORS since I was issuing a jQuery POST to the same web server. The data was JSON but I had omitted the dataType: 'json' parameter.

I did not have (nor did I add) a contentType parameter as shown in David Lopes' answer above.

server.port = 0 for random port

server.port = 8080 for custom 8080 port

An easy way to overcome this problem is to use 64 bit type

list = numpy.array(list, dtype=numpy.float64)

A trick I use that works on more than just Mobile Safari is to use HTML escape codes and a little mark-up in the phone number. This makes it more difficult for the browser to "identify" a phone number, i.e.

Phone: 1-8&#48;&#48;<span>-</span>62&#48;<span>-</span>38&#48;3

I had this issue because my website did not have a certificate bound to the SSL port. I thought I'd mention it because I didn't find this answer anywhere in the googleweb and it took me hours to figure it out. Nothing showed up in the event viewer, which was totally awesome for diagnosing it. Hope this saves someone else the pain.

Finally, I've defeated my CiSCO EAP-FAST corporate wifi network, and all our Android devices are now able to connect to it.

The walk-around I've performed in order to gain access to this kind of networks from an Android device are easiest than you can imagine.

There's a Wifi Config Editor in the Google Play Store you can use to "activate" the secondary CISCO Protocols when you are setting up a EAP wifi connection.

Its name is Wifi Config Advanced Editor.

• First, you have to setup your wireless network manually as close as you can to your "official" corporate wifi parameters.

• Save it.

• Go to the WCE and edit the parameters of the network you have created in the previous step.

• There are 3 or 4 series of settings you should activate in order to force the Android device to use them as a way to connect (the main site I think you want to visit is Enterprise Configuration, but don't forget to check all the parameters to change them if needed.
  As a suggestion, even if you have a WPA2 EAP-FAST Cipher, try LEAP in your setup. It worked for me as a charm.

• When you finished to edit the config, go to the main Android wifi controller, and force to connect to this network.

• Do not Edit the network again with the Android wifi interface.

I have tested it on Samsung Galaxy 1 and 2, Note mobile devices, and on a Lenovo Thinkpad Tablet.

git rebase -i HEAD^^^

Now mark the ones you want to amend with edit or e (replace pick). Now save and exit.

Now make your changes, then

git add .
git rebase --continue

If you want to add an extra delete remove the options from the commit command. If you want to adjust the message, omit just the --no-edit option.

You just need to add this line to the window there:

exec (your stored proc name) (and possibly add parameters)

What is your stored proc called, and what parameters does it expect?

Make an jInternalFrame into main frame and make it invisible. Then you can use it for further events.

jInternalFrame.setSize(300,150);
jInternalFrame.setVisible(true);

Please write following code in menu.xml file:

<menu xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:my_menu_tutorial_app="http://schemas.android.com/apk/res-auto"
      xmlns:tools="http://schemas.android.com/tools"
      tools:context="com.example.mymenus.menu_app.MainActivity">
<item android:id="@+id/item_one"
      android:icon="@drawable/menu_icon"
      android:orderInCategory="l01"
      android:title="Item One"
      my_menu_tutorial_app:showAsAction="always">
      <!--sub-menu-->
      <menu>
          <item android:id="@+id/sub_one"
                android:title="Sub-menu item one" />
          <item android:id="@+id/sub_two"
                android:title="Sub-menu item two" />
      </menu>

Also write this java code in activity class file:

public boolean onOptionsItemSelected(MenuItem item)
{
    super.onOptionsItemSelected(item);
    Toast.makeText(this, "Menus item selected: " +
        item.getTitle(), Toast.LENGTH_SHORT).show();
    switch (item.getItemId())
    {
        case R.id.sub_one:
            isItemOneSelected = true;
            supportInvalidateOptionsMenu();
            return true;
        case MENU_ITEM + 1:
            isRemoveItem = true;
            supportInvalidateOptionsMenu();
            return true;
        default:
            return false;
    }
}

This is the easiest way to display menus in action bar.

ReLU(x) also is equal to (x+abs(x))/2

let me make it more clear

function changeStringToVariable(variable, value){
window[variable]=value
}
changeStringToVariable("name", "john doe");
console.log(name);
//this outputs: john doe
let file="newFile";
changeStringToVariable(file, "text file");
console.log(newFile);
//this outputs: text file

get radio value by name

 $('input').on('className', function(event){
        console.log($(this).attr('name'));
        if($(this).attr('name') == "worker")
            {
                resetAll();                 
            }
    });

Because you can't count on a particular font being available, a good approach is to derive a new font from the current font. This gives you the same family, weight, etc. just larger...

Font currentFont = g.getFont();
Font newFont = currentFont.deriveFont(currentFont.getSize() * 1.4F);
g.setFont(newFont);

You can also use TextAttribute.

Map<TextAttribute, Object> attributes = new HashMap<>();

attributes.put(TextAttribute.FAMILY, currentFont.getFamily());
attributes.put(TextAttribute.WEIGHT, TextAttribute.WEIGHT_SEMIBOLD);
attributes.put(TextAttribute.SIZE, (int) (currentFont.getSize() * 1.4));
myFont = Font.getFont(attributes);

g.setFont(myFont);

The TextAttribute method often gives one even greater flexibility. For example, you can set the weight to semi-bold, as in the example above.

One last suggestion... Because the resolution of monitors can be different and continues to increase with technology, avoid adding a specific amount (such as getSize()+2 or getSize()+4) and consider multiplying instead. This way, your new font is consistently proportional to the "current" font (getSize() * 1.4), and you won't be editing your code when you get one of those nice 4K monitors.

Your should really use the INFORMATION_SCHEMA views in your database:

USE <your_database_name>
GO
SELECT * FROM INFORMATION_SCHEMA.TABLES

You can then filter that by table schema and/or table type, e.g.

SELECT * FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_TYPE='BASE TABLE'

Follow,

$: git checkout -f

$: git checkout next_branch

I encountered a similar issue, I created a 'foo' folder and created a "class" inside foo, then I get the aforementioned error. One fix is to add "static" as earlier mentioned to the class which will be "public static class LinqHelper".

My assumption is that when you create a class inside the foo folder it regards it as an extension class, hence the following inter alia rule apply to it:

1) Every extension method must be a static method

WORKAROUND If you don't want static. My workaround was to create a class directly under the namespace and then drag it to the "foo" folder.

Using array_key_exists() on objects is Deprecated in php 7.4

Instead either isset() or property_exists() should be used

STEP1: I created a field of type varbinary in table

STEP2: I created a stored procedure to accept a parameter of type sql_variant

STEP3: In my front end asp.net page, I created a sql data source parameter of object type

        <tr>
        <td>
            UPLOAD DOCUMENT</td>
        <td>
            <asp:FileUpload ID="FileUpload1" runat="server" />
            <asp:Button ID="btnUpload" runat="server" Text="Upload" />
            <asp:SqlDataSource ID="sqldsFileUploadConn" runat="server" 
                ConnectionString="<%$ ConnectionStrings: %>" 
                InsertCommand="ph_SaveDocument"     
               InsertCommandType="StoredProcedure">
                <InsertParameters>
                    <asp:Parameter Name="DocBinaryForm" Type="Object" />
                </InsertParameters>

             </asp:SqlDataSource>
        </td>
        <td>
            &nbsp;</td>
    </tr>

STEP 4: In my code behind, I try to upload the FileBytes from FileUpload Control via this stored procedure call using a sql data source control

      Dim filebytes As Object
      filebytes = FileUpload1.FileBytes()
      sqldsFileUploadConn.InsertParameters("DocBinaryForm").DefaultValue = filebytes.ToString
      Dim uploadstatus As Int16 = sqldsFileUploadConn.Insert()

               ' ... code continues ... '

You can try this script out since you do not want to target the Xoom only. I don't have a Xoom, but should work.

function mobile_detect(mobile,tablet,mobile_redirect,tablet_redirect,debug) {
var ismobile = (/iphone|ipod|android|blackberry|opera|mini|windows\sce|palm|smartphone|iemobile/i.test(navigator.userAgent.toLowerCase()));
var istablet = (/ipad|android|android 3.0|xoom|sch-i800|playbook|tablet|kindle/i.test(navigator.userAgent.toLowerCase()));

if (debug == true) {
    alert(navigator.userAgent);
}

if (ismobile && mobile==true) {
    if (debug == true) {
        alert("Mobile Browser");
    }
    window.location = mobile_redirect;
} else if (istablet && tablet==true) {
    if (debug == true) {
        alert("Tablet Browser");
    }
    window.location = tablet_redirect;
}
}

I created a project on github. Check it out - https://github.com/codefuze/js-mobile-tablet-redirect. Feel free to submit issues if there is anything wrong!

If you don't mind using a library instead of rolling your own implementation, check out https://github.com/jgallen23/querystring.

If the URL is using https instead of http, you need to add the following line:

parsed_url = URI.parse(url)
http = Net::HTTP.new(parsed_url.host, parsed_url.port)
http.use_ssl = true

Note the additional http.use_ssl = true.

And the more appropriate code which would handle both http and https will be similar to the following one.

url = URI.parse(domain)
req = Net::HTTP::Post.new(url.request_uri)
req.set_form_data({'name'=>'Sur Max', 'email'=>'[email protected]'})
http = Net::HTTP.new(url.host, url.port)
http.use_ssl = (url.scheme == "https")
response = http.request(req)

See more in my blog: EOFError: end of file reached issue when post a form with Net::HTTP.

To spool from a BEGIN END block is pretty simple. For example if you need to spool result from two tables into a file, then just use the for loop. Sample code is given below.

BEGIN

FOR x IN 
(
    SELECT COLUMN1,COLUMN2 FROM TABLE1
    UNION ALL
    SELECT COLUMN1,COLUMN2 FROM TABLEB
)    
LOOP
    dbms_output.put_line(x.COLUMN1 || '|' || x.COLUMN2);
END LOOP;

END;
/

None of that stuff worked. Here's a much simpler way .. the label str is the pointer to what IS an array...

String str = String(yourNumber, DEC); // Obviously .. get your int or byte into the string

str = str + '\r' + '\n'; // Add the required carriage return, optional line feed

byte str_len = str.length();

// Get the length of the whole lot .. C will kindly
// place a null at the end of the string which makes
// it by default an array[].
// The [0] element is the highest digit... so we
// have a separate place counter for the array...

byte arrayPointer = 0;

while (str_len)
{
    // I was outputting the digits to the TX buffer

    if ((UCSR0A & (1<<UDRE0))) // Is the TX buffer empty?
    {
        UDR0 = str[arrayPointer];
        --str_len;
        ++arrayPointer;
    }
}

select * from <table>
where <dateValue> between last_day(curdate() - interval 1 month + interval 1 day)
                  and curdate();

I had the same problem and solved with '%' operator:

select 12.54 % 1;

(more of a related suggestion)

I wanted to have a way of letting the programmer know "do not call from child" and to override completely (in my case still offer some default functionality on behalf of the parent when not extended):

typedef void override_void;
typedef id override_id;

@implementation myBaseClass

// some limited default behavior (undesired by subclasses)
- (override_void) doSomething;
- (override_id) makeSomeObject;

// some internally required default behavior
- (void) doesSomethingImportant;

@end

The advantage is that the programmer will SEE the "override" in the declaration and will know they should not be calling [super ..].

Granted, it is ugly having to define individual return types for this, but it serves as a good enough visual hint and you can easily not use the "override_" part in a subclass definition.

Of course a class can still have a default implementation when an extension is optional. But like the other answers say, implement a run-time exception when appropriate, like for abstract (virtual) classes.

It would be nice to have built in compiler hints like this one, even hints for when it is best to pre/post call the super's implement, instead of having to dig through comments/documentation or... assume.

If you want to use the new current standard, you can do so:

sub.emplace_back ("Math", 70, 0);

or

sub.push_back ({"Math", 70, 0});

These don't require default construction of subject.

To make it work in Chrome (and bootply) i had to change code in this way:

<form class="form-horizontal">
  <div class="form-group">
    <label for="name" class="col-xs-2 control-label">Name</label>
    <div class="col-xs-10">
      <input type="text" class="form-control col-sm-10" name="name" placeholder="name" />
    </div>
  </div>

  <div class="form-group">
    <label for="birthday" class="col-xs-2 control-label">Birthday</label>
    <div class="col-xs-10">
      <div class="form-inline">
        <input type="text" class="form-control" placeholder="year" />
        <input type="text" class="form-control" placeholder="month" />
        <input type="text" class="form-control" placeholder="day" />
      </div>
    </div>
  </div>
</form>
