Some special characters give this type of error, so use

$query="INSERT INTO `tablename` (`name`, `email`)
VALUES
('$_POST[name]','$_POST[email]')";

To diagnose this error quickly drop to a terminal or use the terminal built into Android Studio (accessible on in bottom status bar). Change to the main directory for your PROJECT (where settings.gradle is located).

1.) Check to make sure your settings.gradle includes the subproject. Something like this. This ensures your multi-project build knows about your library sub-project.

include ':apps:App1', ':apps:App2', ':library:Lib1'

Where the text between the colons are sub-directories.

2.) Run the following gradle command just see if Gradle can give you a list of tasks for the library. Use the same qualifier in the settings.gradle definition. This will uncover issues with the Library build script in isolation.

./gradlew :library:Lib1:tasks --info

3.) Make sure the output from the last step listed an "assembleDefault" task. If it didn't make sure the Library is including the Android Library plugin in build.gradle. Like this at the very top.

apply plugin: 'com.android.library'

I know the original poster's question was answered but I believe the answer has evolved over the past year and I think there are multiple reasons for the error. I think this resolution flow should assist those who run into the various issues.

FYI: I know this is a bit late but for anyone who is interested. Depends on how RESTful you want to be, you will have to implement your own filtering strategies as the HTTP spec is not very clear on this. I'd like to suggest url-encoding all the filter parameters e.g.

GET api/users?filter=param1%3Dvalue1%26param2%3Dvalue2

I know it's ugly but I think it's the most RESTful way to do it and should be easy to parse on the server side :)

You need to escape backslash with a \

  $str = str_replace ("\\", "/", $str);

Thanks Paul-g for your advise. For my part it was a bit different.

I installed Boost by following the Step 5 of : https://www.boost.org/doc/libs/1_59_0/more/getting_started/unix-variants.html

And then I add PATH directory in the "FindBoos.cmake", located in /usr/local/share/cmake-3.5/Modules :

SET (BOOST_ROOT "../boost_1_60_0")
SET (BOOST_INCLUDEDIR "../boost_1_60_0/boost")
SET (BOOST_LIBRARYDIR "../boost_1_60_0/libs")

SET (BOOST_MIN_VERSION "1.55.0")
set (Boost_NO_BOOST_CMAKE ON)

Basically git commit "records changes to the repository" while git push "updates remote refs along with associated objects". So the first one is used in connection with your local repository, while the latter one is used to interact with a remote repository.

Here is a nice picture from Oliver Steele, that explains the git model and the commands:

I assume you are using windows. Open the command prompt and type ipconfig and find out your local address (on your pc) it should look something like 192.168.1.13 or 192.168.0.5 where the end digit is the one that changes. It should be next to IPv4 Address.

If your WAMP does not use virtual hosts the next step is to enter that IP address on your phones browser ie http://192.168.1.13 If you have a virtual host then you will need root to edit the hosts file.

If you want to test the responsiveness / mobile design of your website you can change your user agent in chrome or other browsers to mimic a mobile.

See http://googlesystem.blogspot.co.uk/2011/12/changing-user-agent-new-google-chrome.html.

Edit: Chrome dev tools now has a mobile debug tool where you can change the size of the viewport, spoof user agents, connections (4G, 3G etc).

If you get forbidden access then see this question WAMP error: Forbidden You don't have permission to access /phpmyadmin/ on this server. Basically, change the occurrances of deny,allow to allow,deny in the httpd.conf file. You can access this by the WAMP menu.

To eliminate possible causes of the issue for now set your config file to

<Directory />
    Options FollowSymLinks
    AllowOverride All
    Order allow,deny
    Allow from all
    <RequireAll>
        Require all granted
    </RequireAll>
</Directory>

As thatis working for my windows PC, if you have the directory config block as well change that also to allow all.

Config file that fixed the problem:

https://gist.github.com/samvaughton/6790739

Problem was that the /www apache directory config block still had deny set as default and only allowed from localhost.

Just type your desired drive initial in the command line and press enter

Like if you want to go L:\\ drive, Just type L: or l:

You have to configure SMTP on your server. You can use G Suite SMTP by Google for free:

<?php

$mail = new PHPMailer(true);

// Send mail using Gmail
if($send_using_gmail){
    $mail->IsSMTP(); // telling the class to use SMTP
    $mail->SMTPAuth = true; // enable SMTP authentication
    $mail->SMTPSecure = "ssl"; // sets the prefix to the servier
    $mail->Host = "smtp.gmail.com"; // sets GMAIL as the SMTP server
    $mail->Port = 465; // set the SMTP port for the GMAIL server
    $mail->Username = "[email protected]"; // GMAIL username
    $mail->Password = "your-gmail-password"; // GMAIL password
}

// Typical mail data
$mail->AddAddress($email, $name);
$mail->SetFrom($email_from, $name_from);
$mail->Subject = "My Subject";
$mail->Body = "Mail contents";

try{
    $mail->Send();
    echo "Success!";
} catch(Exception $e){
    // Something went bad
    echo "Fail :(";
}

?>

This should work:

$('.myClass, .myOtherClass').removeClass('theclass');

You must add the multiple selectors all in the first argument to $(), otherwise you are giving jQuery a context in which to search, which is not what you want.

It's the same as you would do in CSS.

To illustrate Nippysaurus's answer: If you are going to add the new items to the list and want to process the newly added items too during the same enumeration then you can just use for loop instead of foreach loop, problem solved :)

var list = new List<YourData>();
... populate the list ...

//foreach (var entryToProcess in list)
for (int i = 0; i < list.Count; i++)
{
    var entryToProcess = list[i];

    var resultOfProcessing = DoStuffToEntry(entryToProcess);

    if (... condition ...)
        list.Add(new YourData(...));
}

For runnable example:

void Main()
{
    var list = new List<int>();
    for (int i = 0; i < 10; i++)
        list.Add(i);

    //foreach (var entry in list)
    for (int i = 0; i < list.Count; i++)
    {
        var entry = list[i];
        if (entry % 2 == 0)
            list.Add(entry + 1);

        Console.Write(entry + ", ");
    }

    Console.Write(list);
}

Output of last example:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 1, 3, 5, 7, 9,

List (15 items)

Windows 7 requires that you intentionally ask for certain privileges so that a malicious program can't do bad things to you. If the free calculator you downloaded needed to be run as an administrator, you would know something is up. There are OS commands to elevate the privilege of your application (which will request confirmation from the user).

A good description can be found at:

Long story short,
IQueryable is designed to postpone RUN process and firstly build the expression in conjunction with other IQueryable expressions, and then interprets and runs the expression as a whole.
But ToList() method (or a few sort of methods like that), are ment to run the expression instantly "as is".
Your first method (GetAllUrlsAsync), will run imediately, because it is IQueryable followed by ToListAsync() method. hence it runs instantly (asynchronous), and returns a bunch of IEnumerables.
Meanwhile your second method (GetAllUrls), won't get run. Instead, it returns an expression and CALLER of this method is responsible to run the expression.

int newArrayLength = 30; 

int[] newArray = new int[newArrayLength];

System.arrayCopy(oldArray, 0, newArray, 0, newArray.length);

It sounds like the server is having trouble handling POST requests (get and post are verbs). I don't know, how or why someone would configure a server to ignore post requests, but the only solution would be to fix the server, or change your app to use get requests.

You should look into Zip Packages

They are a more structured version of normal ZIP archives, requiring some meta stuff in the root. So other ZIP tools can open a package, but the Sysytem.IO.Packaging API can not open all ZIP files.

Check out my article Protect Your Java Code - Through Obfuscators And Beyond [Archived] for a discussion of obfuscation vs three other ways to make the reverse engineering of your apps more expensive, and a collection of links to tools and further reading materials.

This is the correct and tested solution

Use git clone with the --depth option set to 1 to create a shallow clone with a history truncated to the latest commit.

For example:

git clone --depth 1 https://github.com/user/repo.git

To also initialize and update any nested submodules, also pass --recurse-submodules and to clone them shallowly, also pass --shallow-submodules.

For example:

git clone --depth 1 --recurse-submodules --shallow-submodules https://github.com/user/repo.git

Here is an option if you are using pandas:

import pandas as pd

d = dict.fromkeys(['a', 'b', 'c', 'd'])
d['b'] = 'not null'
d['c'] = ''  # empty string

print(d)

# convert `dict` to `Series` and replace any blank strings with `None`;
# use the `.dropna()` method and
# then convert back to a `dict`
d_ = pd.Series(d).replace('', None).dropna().to_dict()

print(d_)

Lots of answers so far, which are all excellent pointers to API's and tutorials. One thing I'd like to add is that I work out how far the markers are from my location using something like:

float distance = (float) loc.distanceTo(loc2);

Hope this helps refine the detail for your problem. It returns a rough estimate of distance (in m) between points, and is useful for getting rid of POI that might be too far away - good to declutter your map?

a bit late to this, but yes rabbitmq has a build in tracer that allows you to see the incomming messages in a log. When enabled, you can just tail -f /var/tmp/rabbitmq-tracing/.log (on mac) to watch the messages.

the detailed discription is here http://www.mikeobrien.net/blog/tracing-rabbitmq-messages

document.getElementsByClassName("classstringhere").length

The document.getElementsByClassName("classstringhere") method returns an array of all the elements with that class name, so .length gives you the amount of them.

If the author has a GitHub account, just click the author's username from anywhere in the commit history, and the commits you can see will be filtered down to those by that author:

You can also click the 'n commits' link below their name on the repo's "contributors" page:

Alternatively, you can directly append ?author=<theusername> or ?author=<emailaddress> to the URL. For example, https://github.com/jquery/jquery/commits/master?author=dmethvin or https://github.com/jquery/jquery/commits/[email protected] both give me:

For authors without a GitHub account, only filtering by email address will work, and you will need to manually add ?author=<emailaddress> to the URL - the author's name will not be clickable from the commits list.

You can also get the list of commits by a particular author from the command line using

git log --author=[your git name]

Example:

git log --author=Prem

While this does not address the OP's question, I had trouble with my bootstrap rows / columns while trying to use them in conjunction with Kendo ListView (even with the bootstrap-kendo css).

Adding the following css fixed the problem for me:

#myListView.k-widget, #catalog-items.k-widget * {
    -webkit-box-sizing: border-box;
    box-sizing: border-box;
}

In my legacy app Array.from of prototype js was conflicting with angular's Array.from that was causing this problem. I resolved it by saving angular's Array.from version and reassigning it after prototype load.

My solution to hiding a DB-Password in Spring Boot App's application.properties does implemented here.

Scenario: some fake password already reading and saved from application.properties on start, in global Spring object ConfigurableEnvironment will be, in Run-Time replaced programmaticaly, by real DB-Password. The real password will be reading from another config file, saved in safe, project-outer place.

Don't forget: call the the Bean from main class with:

@Autowired
private SchedUtilility utl;

Queue

Queue is a ordered collection of items.

Items are deleted at one end called ‘front’ end of the queue.

Items are inserted at other end called ‘rear’ of the queue.

The first item inserted is the first to be removed (FIFO).

Stack

Stack is a collection of items.

It allows access to only one data item: the last item inserted.

Items are inserted & deleted at one end called ‘Top of the stack’.

It is a dynamic & constantly changing object.

All the data items are put on top of the stack and taken off the top

This structure of accessing is known as Last in First out structure (LIFO)

You can also make a class:

<span class="mychangecolor"> I am in yellow color!!!!!!</span>

then in a css file do:

.mychangecolor{ color:#ff5 /* it changes to yellow */ }

Your Activity is extending ActionBarActivity which requires the AppCompat.theme to be applied. Change from ActionBarActivity to Activity or FragmentActivity, it will solve the problem.

For anyone reading this who is using EclipseLink for JPA 2.0, here are the two annotations I had to use to get JPA to persist data, where "MySequenceGenerator" is whatever name you want to give the generator, "myschema" is the name of the schema in your database that contains the sequence object, and "mysequence" is the name of the sequence object in the database.

@GeneratedValue(strategy= GenerationType.SEQUENCE, generator="MySequenceGenerator")
@SequenceGenerator(allocationSize=1, schema="myschema",  name="MySequenceGenerator", sequenceName = "mysequence")

For those using EclipseLink (and possibly other JPA providers), it is CRITICAL that you set the allocationSize attribute to match the INCREMENT value defined for your sequence in the database. If you don't, you'll get a generic persistence failure, and waste a good deal of time trying to track it down, like I did. Here is the reference page that helped me overcome this challenge:

http://wiki.eclipse.org/EclipseLink/Examples/JPA/PrimaryKey#Using_Sequence_Objects

Also, to give context, here is what we're using:

Java 7 Glassfish 3.1 PostgreSQL 9.1 PrimeFaces 3.2/JSF 2.1

Also, for laziness' sake, I built this in Netbeans with the wizards for generating Entities from DB, Controllers from Entities, and JSF from Entities, and the wizards (obviously) do not know how to deal with sequence-based ID columns, so you'll have to manually add these annotations.

Good Solution is to get Nearest Round Number is

var=2.5
echo $var | awk '{print int($1+0.5)}'

Logic is simple if the var decimal value is less then .5 then closest value taken is integer value. Well if decimal value is more than .5 then next integer value gets added and since awk then takes only integer part. Issue solved

image view add as a sub view to the tableview cell

UIImageView *imgView=[[UIImageView alloc] initWithFrame:CGRectMake(20, 5, 90, 70)];
imgView.backgroundColor=[UIColor clearColor];
[imgView.layer setCornerRadius:8.0f];
[imgView.layer setMasksToBounds:YES];
[imgView setImage:[UIImage imageWithData: imageData]];
[cell.contentView addSubview:imgView];

This might be a little late to answer but most simple and accurate way to compute square root is newton's method.

You have a number which you want to compute its square root (num) and you have a guess of its square root (estimate). Estimate can be any number bigger than 0, but a number that makes sense shortens the recursive call depth significantly.

new_estimate = (estimate + num / estimate) / 2

This line computes a more accurate estimate with those 2 parameters. You can pass new_estimate value to the function and compute another new_estimate which is more accurate than the previous one or you can make a recursive function definition like this.

def newtons_method(num, estimate):
    # Computing a new_estimate
    new_estimate = (estimate + num / estimate) / 2
    print(new_estimate)
    # Base Case: Comparing our estimate with built-in functions value
    if new_estimate == math.sqrt(num):
        return True
    else:
        return newtons_method(num, new_estimate)

For example we need to find 30's square root. We know that the result is between 5 and 6.

newtons_method(30,5)

number is 30 and estimate is 5. The result from each recursive calls are:

5.5
5.477272727272727
5.4772255752546215
5.477225575051661

The last result is the most accurate computation of the square root of number. It is the same value as the built-in function math.sqrt().

I tried the existing answers to this question, and none of them worked on Chrome for me. What did work was slightly different:

$('body, html, #containerDiv').scrollTop(0);

If you dont want to format a separate column with you normal dates pasted to it -- do the following -- add a column to the extreme left of your data and reverve your date ie if the date you had already entered was for example 11.5.16 enter int he new lefthand column 160511 ( notice that there are numbers only and no full stops . When you now sort there will be no mix ups as you have encountered.i have used this method for over 30 years and it never lets me down. And as you have placed the date by year, month and day you neednt include that column if you want or need tu print out your complete list.

var boxSummary = from b in boxes
                 group b by b.Owner into g
                 let nrBoxes = g.Count()
                 let totalWeight = g.Sum(w => w.Weight)
                 let totalVolume = g.Sum(v => v.Volume)
                 select new { Owner = g.Key, Boxes = nrBoxes,
                              TotalWeight = totalWeight,
                              TotalVolume = totalVolume }

You can also use extremely small numbers for your radius'.

<corners 
  android:bottomRightRadius="0.1dp" android:bottomLeftRadius="2dp" 
 android:topLeftRadius="2dp" android:topRightRadius="0.1dp" />

As well as find listed in other answers, better shells allow both recurvsive globs and filtering of glob matches, so in zsh for example...

ls -lad **/*(/)

...lists all directories while keeping all the "-l" details that you want, which you'd otherwise need to recreate using something like...

find . -type d -exec ls -ld {} \;

(not quite as easy as the other answers suggest)

The benefit of find is that it's more independent of the shell - more portable, even for system() calls from within a C/C++ program etc..

Since it hasnt really been confirmed in an answer yet, Underscore's reduce also works for this.

_.reduce({ 
    a: {value:1}, 
    b: {value:2}, 
    c: {value:3} 
}, function(prev, current){
    //prev is either first object or total value
    var total = prev.value || prev

    return total + current.value
})

Note, _.reduce will return the only value (object or otherwise) if the list object only has one item, without calling iterator function.

_.reduce({ 
    a: {value:1} 
}, function(prev, current){
    //not called
})

//returns {value: 1} instead of 1

Follow this :)

1. Open : /etc/systemd/system/tomcat.service

Can you see JAVA_HOME ? : modify it like below

Environment="JAVA_HOME=/usr/lib/jvm/java-1.11.0-openjdk-amd64"

At 1.11.0 - insert your own Jdk version

2. systemctl daemon-reload

3. sudo systemctl start tomcat

Now, in eclipse -> Add Server -> .....

Got struck at tomcat installation directory ??

1. Extract the tomcat tar file you already downloaded.
2. Now go back to eclipse -> add server -> Browse -> Point to extracted file (done in step 1 above :)

Comment if you get struck in somewhere else too )

Instead of inverting, you can achieve the same goal by using a generic IValueConverter implementation that can convert a Boolean value to configurable target values for true and false. Below is one such implementation:

public class BooleanConverter<T> : IValueConverter
{
    public BooleanConverter(T trueValue, T falseValue)
    {
        True = trueValue;
        False = falseValue;
    }

    public T True { get; set; }
    public T False { get; set; }

    public virtual object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        return value is bool && ((bool) value) ? True : False;
    }

    public virtual object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        return value is T && EqualityComparer<T>.Default.Equals((T) value, True);
    }
}

Next, subclass it where T is Visibility:

public sealed class BooleanToVisibilityConverter : BooleanConverter<Visibility>
{
    public BooleanToVisibilityConverter() : 
        base(Visibility.Visible, Visibility.Collapsed) {}
}

Finally, this is how you could use BooleanToVisibilityConverter above in XAML and configure it to, for example, use Collapsed for true and Visible for false:

<Application.Resources>
    <app:BooleanToVisibilityConverter 
        x:Key="BooleanToVisibilityConverter" 
        True="Collapsed" 
        False="Visible" />
</Application.Resources>

This inversion is useful when you want to bind to a Boolean property named IsHidden as opposed IsVisible.

I updated spring tool suits by going help > check for update.

To avoid doing indexing from inside lambda, like:

rval = dict(map(lambda kv : (kv[0], ' '.join(kv[1])), rval.iteritems()))

You can also do:

rval = dict(map(lambda(k,v) : (k, ' '.join(v)), rval.iteritems()))

I have updated my server to GitLab 6.6.4 and finally found the way to get version of GitLab remotely without SSH access to server.

You should be logged in to access the following page: https://your.domain.name/help

It shows something similar to:

GitLab 6.6.4 42e34ae

GitLab is open source software to collaborate on code.

etc.

I experienced this error after a static member variable in my test class called a method to create an object (which was used in test cases throughout the class), and the method caused an exception.

// Object created inside test class by calling a static getter.
// Exception thrown in getter:
private static Object someObject = SomeObject.getObject(...);

// ... <Object later used in class>

Some fixes include recreating the object inside each test case and catching any exceptions accordingly. Or by initializing the object inside an @BeforeTest method and ensuring that it is built properly.

Use the CSS z-index property. Elements with a greater z-index value are positioned in front of elements with smaller z-index values.

Note that for this to work, you also need to set a position style (position:absolute, position:relative, or position:fixed) on both/all of the elements you want to order.

VBScript doesn't have Try/Catch. (VBScript language reference. If it had Try, it would be listed in the Statements section.)

On Error Resume Next is the only error handling in VBScript. Sorry. If you want try/catch, JScript is an option. It's supported everywhere that VBScript is and has the same capabilities.

You can use the GraphRequest class to issue calls to the Facebook Graph API to get user information. See https://developers.facebook.com/docs/android/graph for more info.

First, use git log to see the log, pick the commit you want, note down the sha1 hash that is used to identify the commit. Next, run git checkout hash. After you are done, git checkout original_branch. This has the advantage of not moving the HEAD, it simply switches the working copy to a specific commit.

With Angular 5, I solved a similar problem by ugrading to @angular/cli 1.6.1 from 1.5.5:

"devDependencies": {
  "@angular/cli": "1.6.1"
}

During ng serve the error I got was:

Just to clarify - at least from what we found on our side! It is an issue with the setup of the randomizer for Linux in the JDK distribution - and we found it in Java6, not sure about Java7. The syntax for linux for the randomizer is file:///dev/urandom, but the entry in the file is (probably left/copied from Windows) as file:/dev/urandom. So then Java probably falls back on the default, which happens to be /dev/random. And which doesn't work on a headless machine!!!

You want this method:

boolean isList = List.class.isAssignableFrom(myClass);

where in general, List (above) should be replaced with superclass and myClass should be replaced with subclass

From the JavaDoc:

Determines if the class or interface represented by this Class object is either the same as, or is a superclass or superinterface of, the class or interface represented by the specified Class parameter. It returns true if so; otherwise it returns false. If this Class object represents a primitive type, this method returns true if the specified Class parameter is exactly this Class object; otherwise it returns false.

Reference:

• Class.isAssignableFrom(Class)

Related:

a) Check if an Object is an instance of a Class or Interface (including subclasses) you know at compile time:

boolean isInstance = someObject instanceof SomeTypeOrInterface;

Example:

assertTrue(Arrays.asList("a", "b", "c") instanceof List<?>);

b) Check if an Object is an instance of a Class or Interface (including subclasses) you only know at runtime:

Class<?> typeOrInterface = // acquire class somehow
boolean isInstance = typeOrInterface.isInstance(someObject);

Example:

public boolean checkForType(Object candidate, Class<?> type){
    return type.isInstance(candidate);
}

DECLARE @a int=1000, @b int=1050
SELECT @a-1+ROW_NUMBER() OVER(ORDER BY y.z.value('(/n)[1]', 'int') ) rw
FROM (
SELECT CAST('<m>'+REPLICATE('<n>1</n>', @b-@a+1)+'</m>' AS XML ) x ) t
CROSS APPLY t.x.nodes('//m/n') y(z)

I know this is old, but... Another option may be to use the FileSystemWatcher like so:

void SomeMethod()
{
    System.IO.FileSystemWatcher m_Watcher = new System.IO.FileSystemWatcher();
    m_Watcher.Path = path;
    m_Watcher.Filter = "*.*";
    m_Watcher.NotifyFilter = m_Watcher.NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite | NotifyFilters.FileName | NotifyFilters.DirectoryName;
    m_Watcher.Created += new FileSystemEventHandler(OnChanged);
    m_Watcher.EnableRaisingEvents = true;
}

private void OnChanged(object sender, FileSystemEventArgs e)
    {
        string path = e.FullPath;

        lock (listLock)
        {
            pathsToUpload.Add(path);
        }
    }

This would allow you to watch the directories for file changes with an extremely lightweight process, that you could then use to store the names of the files that changed so that you could back them up at the appropriate time.

Further to what Steve Baker has said, you can find a description of the SIOCGIFCONF ioctl in the netdevice(7) man page.

Once you have the list of all the IP addresses on the host, you will have to use application specific logic to filter out the addresses you do not want and hope you have one IP address left.

For UILable

extension UILabel {
    func underline() {
        if let textString = self.text {
            let attributedString = NSMutableAttributedString(string: textString)
            attributedString.addAttribute(NSAttributedString.Key.underlineStyle,
                                          value: NSUnderlineStyle.single.rawValue,
                                          range: NSRange(location: 0, length: textString.count))
            self.attributedText = attributedString
        }
    }
}

Call for UILabel like below

myLable.underline()

For UIButton

extension UIButton {
    func underline() {
        if let textString = self.titleLabel?.text {

            let attributedString = NSMutableAttributedString(string: textString)
            attributedString.addAttribute(NSAttributedString.Key.underlineStyle,
                                          value: NSUnderlineStyle.single.rawValue,
                                          range: NSRange(location: 0, length: textString.count))
            self.setAttributedTitle(attributedString, for: .normal)
        }

    }
}

Call for UIButton like below

myButton.underline()

I looked into above answers and some of them are force unwrapping text value. I will suggest to get value by safely unwrapping. This will avoid crash in case of nil value. Hope This helps :)

You can use the RTrim function to trim all whitespace from the right. Use LTrim to trim all whitespace from the left. For example

UPDATE Table SET Name = RTrim(Name)

Or for both left and right trim

UPDATE Table SET Name = LTrim(RTrim(Name))

I found this can also occur if the most of the data plotted is outside of the axis limits. In that case, adjust the axis scales accordingly.

In order to change the data source from the ribbon in excel 2007...

Click on your pivot table in the worksheet. Go to the ribbon where it says Pivot Table Tools, Options Tab. Select the Change Data Source button. A dialog box will appear.

To get the right range and avoid an error message... select the contents of the existing field and delete it, then switch to the new data source worksheet and highlight the data area (the dialog box will stay on top of all windows). Once you've selected the new data source correctly, it will fill in the blank field (which you deleted before) in the dialog box. Click OK. Switch back to your pivot table and it should have updated with the new data from the new source.

A CRC is pretty simple; you take a polynomial represented as bits and the data, and divide the polynomial into the data (or you represent the data as a polynomial and do the same thing). The remainder, which is between 0 and the polynomial is the CRC. Your code is a bit hard to understand, partly because it's incomplete: temp and testcrc are not declared, so it's unclear what's being indexed, and how much data is running through the algorithm.

The way to understand CRCs is to try to compute a few using a short piece of data (16 bits or so) with a short polynomial -- 4 bits, perhaps. If you practice this way, you'll really understand how you might go about coding it.

If you're doing it frequently, a CRC is quite slow to compute in software. Hardware computation is much more efficient, and requires just a few gates.

I also had some trouble with my scrollable modals, so I did something like this:

  $('.modal').on('shown.bs.modal', function () {
    $('body').addClass('modal-open');
    // BS adds some padding-right to acomodate the scrollbar at right
    $('body').removeAttr('style');
  })

  $(".modal [data-toggle='modal']").click(function(){
    $(this).closest(".modal").modal('hide');
  });

It will serve for any modal whithin a modal that comes to appear. Note that the first its closed so the second can appear. No changes in the Bootstrap structure.

Callbacks are about signals and "new" is about creating object instances.

In this case it would be even more appropriate to execute just "callback();" than "return new callback()" because you aren't doing anything with a return value anyway.

(And the arguments.length==3 test is really clunky, fwiw, better to check that callback param exists and is a function.)

After installing Free BitDefender AntiVirus the services related to the AntiVirus used about 80 MB of my computer's Memory. I also noticed that after installing BitDefender the service related to windows Presentation Font Cache was also installed: "WPFFontCache_v0300.exe". I disabled the service from stating automatically and now BitDefender Free AntiVirus use only 15-20 MB (!!!) of my computer's Memory! As far as I concern, this service affected negatively the memory usage of my PC inother services. I recommend you to disable it.

This happens if you initialized a new github repo with README and/or LICENSE file

git remote add origin [//your github url]

//pull those changes

git pull origin master 

// or optionally, 'git pull origin master --allow-unrelated-histories' if you have initialized repo in github and also committed locally

//now, push your work to your new repo

git push origin master

Now you will be able to push your repository to github. Basically, you have to merge those new initialized files with your work. git pull fetches and merges for you. You can also fetch and merge if that suits you.

Here is another way of doing this by using es6 template literals dynamically at runtime.

const str = 'My name is ${name} and my age is ${age}.'_x000D_
const obj = {name:'Simon', age:'33'}_x000D_
_x000D_
_x000D_
const result = new Function('const {' + Object.keys(obj).join(',') + '} = this.obj;return `' + str + '`').call({obj})_x000D_
_x000D_
document.body.innerHTML = result

You can use DatePipe for formatting Date in Angular.

In ts if you want to format date then you can inject DatePipe as Service in constructor like this

import { DatePipe } from '@angular/common';

@Component({
    templateUrl: './name.component.html',
    styleUrls: ['./name.component.scss'],
    providers: [DatePipe]
})

myDate = new Date();
constructor(private datePipe: DatePipe){
    this.myDate = this.datePipe.transform(this.myDate, 'yyyy-MM-dd');
}

And if you want to format in html file, 'Shortdate' will return date of type MM/DD/YY

{{myDate | date: 'shortDate' }}

As of Angular 6, this also works,

import {formatDate} from '@angular/common';

formatDate(new Date(), 'yyyy/MM/dd', 'en');

You're using jQuery version 3.1.0 and the load event is deprecated for use since jQuery version 1.8. The load event is removed from jQuery 3.0. Instead you can use on method and bind the JavaScript load event:

 $(window).on('load', function () {
      alert("Window Loaded");
 });

<script type="text/javascript">
window.setTimeout("location=('timeout_session.htm');",900000);
</script>

In the header of every page has been working for me during site tests(the site is not yet in production). The HTML page it falls to ends the session and just informs the user of the need to log in again. This seems an easier way than playing with PHP logic. I'd love some comments on the idea. Any traps I havent seen in it ?

A 32-bit process is still limited to the same constraints in a 64-bit OS. The issue is that memory pointers are only 32-bits wide, so the program can't assign/resolve any memory address larger than 32 bits.

In the Google Maps API v2 Demo there is a MarkerDemoActivity class in which you can see how a custom Image is set to a GoogleMap.

// Uses a custom icon.
mSydney = mMap.addMarker(new MarkerOptions()
    .position(SYDNEY)
    .title("Sydney")
    .snippet("Population: 4,627,300")
    .icon(BitmapDescriptorFactory.fromResource(R.drawable.arrow)));

As this just replaces the marker with an image you might want to use a Canvas to draw more complex and fancier stuff:

Bitmap.Config conf = Bitmap.Config.ARGB_8888;
Bitmap bmp = Bitmap.createBitmap(80, 80, conf);
Canvas canvas1 = new Canvas(bmp);

// paint defines the text color, stroke width and size
Paint color = new Paint();
color.setTextSize(35);
color.setColor(Color.BLACK);

// modify canvas
canvas1.drawBitmap(BitmapFactory.decodeResource(getResources(),
    R.drawable.user_picture_image), 0,0, color);
canvas1.drawText("User Name!", 30, 40, color);

// add marker to Map
mMap.addMarker(new MarkerOptions()
    .position(USER_POSITION)
    .icon(BitmapDescriptorFactory.fromBitmap(bmp))
    // Specifies the anchor to be at a particular point in the marker image.
    .anchor(0.5f, 1));

This draws the Canvas canvas1 onto the GoogleMap mMap. The code should (mostly) speak for itself, there are many tutorials out there how to draw a Canvas. You can start by looking at the Canvas and Drawables from the Android Developer page.

Now you also want to download a picture from an URL.

URL url = new URL(user_image_url);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();   
conn.setDoInput(true);   
conn.connect();     
InputStream is = conn.getInputStream();
bmImg = BitmapFactory.decodeStream(is); 

You must download the image from an background thread (you could use AsyncTask or Volley or RxJava for that).

After that you can replace the BitmapFactory.decodeResource(getResources(), R.drawable.user_picture_image) with your downloaded image bmImg.

I was doing some volume rendering in octave (matlab clone) and building my 3D arrays (ie an array of 2d slices) using

buffer=zeros(1,512*512*512,"uint16");
vol=reshape(buffer,512,512,512);

Memory consumption seemed to be efficient. (can't say the same for the subsequent speed of computations :^)

I would create a user control which holds a Label and a Text Box in it and simply create instances of that user control 'n' times. If you want to know a better way to do it and use properties to get access to the values of Label and Text Box from the user control, please let me know.

Simple way to do it would be:

int n = 4; // Or whatever value - n has to be global so that the event handler can access it

private void btnDisplay_Click(object sender, EventArgs e)
{
    TextBox[] textBoxes = new TextBox[n];
    Label[] labels = new Label[n];

    for (int i = 0; i < n; i++)
    {
        textBoxes[i] = new TextBox();
        // Here you can modify the value of the textbox which is at textBoxes[i]

        labels[i] = new Label();
        // Here you can modify the value of the label which is at labels[i]
    }

    // This adds the controls to the form (you will need to specify thier co-ordinates etc. first)
    for (int i = 0; i < n; i++)
    {
        this.Controls.Add(textBoxes[i]);
        this.Controls.Add(labels[i]);
    }
}

The code above assumes that you have a button btnDisplay and it has a onClick event assigned to btnDisplay_Click event handler. You also need to know the value of n and need a way of figuring out where to place all controls. Controls should have a width and height specified as well.

To do it using a User Control simply do this.

Okay, first of all go and create a new user control and put a text box and label in it.

Lets say they are called txtSomeTextBox and lblSomeLabel. In the code behind add this code:

public string GetTextBoxValue() 
{ 
    return this.txtSomeTextBox.Text; 
} 

public string GetLabelValue() 
{ 
    return this.lblSomeLabel.Text; 
} 

public void SetTextBoxValue(string newText) 
{ 
    this.txtSomeTextBox.Text = newText; 
} 

public void SetLabelValue(string newText) 
{ 
    this.lblSomeLabel.Text = newText; 
}

Now the code to generate the user control will look like this (MyUserControl is the name you have give to your user control):

private void btnDisplay_Click(object sender, EventArgs e)
{
    MyUserControl[] controls = new MyUserControl[n];

    for (int i = 0; i < n; i++)
    {
        controls[i] = new MyUserControl();

        controls[i].setTextBoxValue("some value to display in text");
        controls[i].setLabelValue("some value to display in label");
        // Now if you write controls[i].getTextBoxValue() it will return "some value to display in text" and controls[i].getLabelValue() will return "some value to display in label". These value will also be displayed in the user control.
    }

    // This adds the controls to the form (you will need to specify thier co-ordinates etc. first)
    for (int i = 0; i < n; i++)
    {
        this.Controls.Add(controls[i]);
    }
}

Of course you can create more methods in the usercontrol to access properties and set them. Or simply if you have to access a lot, just put in these two variables and you can access the textbox and label directly:

public TextBox myTextBox;
public Label myLabel;

In the constructor of the user control do this:

myTextBox = this.txtSomeTextBox;
myLabel = this.lblSomeLabel;

Then in your program if you want to modify the text value of either just do this.

control[i].myTextBox.Text = "some random text"; // Same applies to myLabel

Hope it helped :)

I recently moved my local repo from one Windows x64 system to another. The first time I use it half my files appear to be changed. Thanks to Jacek Szybisz for sending me to Configuring Git to handle line endings where I found the following one-liner that removed all the no-change files from Gitkraken's change queue:

git config --global core.autocrlf true

I tried it on XP and it doesn't work if the PC is set to International time yyyy-M-d. Place a breakpoint on the line and before it is processed change the date string to use '-' in place of the '/' and you'll find it works. It makes no difference whether you have the CultureInfo or not. Seems strange to be able specify an expercted format only to have the separator ignored.

I used something like that

$(yourSelector).find('input:checkbox').removeAttr('checked');

Replacing for Removing is not quite logical. String.filter allows to iterate a string char by char and keep only true assertion.

Swift 4 & 5

var aString = "Optional(\"5\")"

aString = aString.filter { $0 != "\"" }

> Optional(5)

Or to extend

var aString = "Optional(\"5\")"

let filteredChars = "\"\n\t"

aString = aString.filter { filteredChars.range(of: String($0)) == nil }

> Optional(5)

Very interesting. I have been able to get my form to work but the resulting email displays:

imageField_x: 80 imageField_y: 17

at the bottom of the email that I get.

Here's my code for the buttons.

    <tr>
      <td><input type="image" src="images/sendmessage.gif" / ></td>
      <td colspan="2"><input type="image" src="images/printmessage.gif"onclick="window.print()"></td>
    </tr>

Maybe this will help you and me as well.

If the user doesn't have Chrome, it will throw an exception like this:

    //chrome.exe http://xxx.xxx.xxx --incognito
    //chrome.exe http://xxx.xxx.xxx -incognito
    //chrome.exe --incognito http://xxx.xxx.xxx
    //chrome.exe -incognito http://xxx.xxx.xxx
    private static void Chrome(string link)
    {
        string url = "";

        if (!string.IsNullOrEmpty(link)) //if empty just run the browser
        {
            if (link.Contains('.')) //check if it's an url or a google search
            {
                url = link;
            }
            else
            {
                url = "https://www.google.com/search?q=" + link.Replace(" ", "+");
            }
        }

        try
        {
            Process.Start("chrome.exe", url + " --incognito");
        }
        catch (System.ComponentModel.Win32Exception e)
        {
            MessageBox.Show("Unable to find Google Chrome...",
                "chrome.exe not found!", MessageBoxButtons.OK, MessageBoxIcon.Error);
        }
    }

Like Jonathan suggested, using textView.setTextTypeface works, I just used it in an app a few seconds ago.

textView.setTypeface(null, Typeface.BOLD); // Typeface.NORMAL, Typeface.ITALIC etc.

I was also in the same problem, check your build path in eclipse by Right Click on Project > build path > configure build path

Now check for Excluded Files, it should not have your file specified there by any means or by regex.

If You want a pythonic way without numpy working in 2.7 this would be my way of doing it

l = [1,2,3,4]
_d={-1:0}
cumsum=[_d.setdefault(idx, _d[idx-1]+item) for idx,item in enumerate(l)]

now let's try it and test it against all other implementations

import timeit, sys
L=list(range(10000))
if sys.version_info >= (3, 0):
    reduce = functools.reduce
    xrange = range


def sum1(l):
    cumsum=[]
    total = 0
    for v in l:
        total += v
        cumsum.append(total)
    return cumsum


def sum2(l):
    import numpy as np
    return list(np.cumsum(l))

def sum3(l):
    return [sum(l[:i+1]) for i in xrange(len(l))]

def sum4(l):
    return reduce(lambda c, x: c + [c[-1] + x], l, [0])[1:]

def this_implementation(l):
    _d={-1:0}
    return [_d.setdefault(idx, _d[idx-1]+item) for idx,item in enumerate(l)]


# sanity check
sum1(L)==sum2(L)==sum3(L)==sum4(L)==this_implementation(L)
>>> True    

# PERFORMANCE TEST
timeit.timeit('sum1(L)','from __main__ import sum1,sum2,sum3,sum4,this_implementation,L', number=100)/100.

To fill a list with seperate instances of a class, you can use a for loop in the declaration of the list. The * multiply will link each copy to the same instance.

instancelist = [ MyClass() for i in range(29)]

and then access the instances through the index of the list.

instancelist[5].attr1 = 'whamma'

You can do:

t1<- t1[-4:-6,-7:-9]

I tried following command and it works fine

conda install -c conda-forge opencv

once you hit the command it will ask for yes or no

If you select yes it will proceed and install all the required packages

A more elegant way I found to achieve this behaviour is simply:

<div id="{{ 'object-' + myScopeObject.index }}"></div>

For my implementation I wanted each input element in a ng-repeat to each have a unique id to associate the label with. So for an array of objects contained inside myScopeObjects one could do this:

<div ng-repeat="object in myScopeObject">
    <input id="{{object.name + 'Checkbox'}}" type="checkbox">
    <label for="{{object.name + 'Checkbox'}}">{{object.name}}</label>
</div>

Being able to generate unique ids on the fly can be pretty useful when dynamically adding content like this.

The data returned by the JSON is in json format : which is simply an arrays of values. Thats why you are seeing [object Object],[object Object],[object Object].

You have to iterate through that values to get actuall value. Like the following

jQuery provides $.each() for iterations, so you could also do this:

$.getJSON("url_with_json_here", function(data){
    $.each(data, function (linktext, link) {
        console.log(linktext);
        console.log(link);
    });
});

Now just create an Hyperlink using that info.

The correct syntax for this is...

Session::set('variableName', $value);

For Laravel 5.4 and later, the correct method to use is put.

Session::put('variableName', $value);

To get the variable, you'd use...

Session::get('variableName');

If you need to set it once, I'd figure out when exactly you want it set and use Events to do it. For example, if you want to set it when someone logs in, you'd use...

Event::listen('auth.login', function()
{
    Session::set('variableName', $value);
});

Per the official guide, use of pylab is no longer recommended. matplotlib.pyplot should be used directly instead.

Globally setting font sizes via rcParams should be done with

import matplotlib.pyplot as plt
plt.rcParams['axes.labelsize'] = 16
plt.rcParams['axes.titlesize'] = 16

# or

params = {'axes.labelsize': 16,
          'axes.titlesize': 16}
plt.rcParams.update(params)

# or

import matplotlib as mpl
mpl.rc('axes', labelsize=16, titlesize=16)

# or 

axes = {'labelsize': 16,
        'titlesize': 16}
mpl.rc('axes', **axes)

The defaults can be restored using

plt.rcParams.update(plt.rcParamsDefault)

You can also do this by creating a style sheet in the stylelib directory under the matplotlib configuration directory (you can get your configuration directory from matplotlib.get_configdir()). The style sheet format is

axes.labelsize: 16
axes.titlesize: 16

If you have a style sheet at /path/to/mpl_configdir/stylelib/mystyle.mplstyle then you can use it via

plt.style.use('mystyle')

# or, for a single section

with plt.style.context('mystyle'):
    # ...

You can also create (or modify) a matplotlibrc file which shares the format

axes.labelsize = 16
axes.titlesize = 16

Depending on which matplotlibrc file you modify these changes will be used for only the current working directory, for all working directories which do not have a matplotlibrc file, or for all working directories which do not have a matplotlibrc file and where no other matplotlibrc file has been specified. See this section of the customizing matplotlib page for more details.

A complete list of the rcParams keys can be retrieved via plt.rcParams.keys(), but for adjusting font sizes you have (italics quoted from here)

• axes.labelsize - Fontsize of the x and y labels
• axes.titlesize - Fontsize of the axes title
• figure.titlesize - Size of the figure title (Figure.suptitle())
• xtick.labelsize - Fontsize of the tick labels
• ytick.labelsize - Fontsize of the tick labels
• legend.fontsize - Fontsize for legends (plt.legend(), fig.legend())
• legend.title_fontsize - Fontsize for legend titles, None sets to the same as the default axes. See this answer for usage example.

all of which accept string sizes {'xx-small', 'x-small', 'smaller', 'small', 'medium', 'large', 'larger', 'x-large', 'xxlarge'} or a float in pt. The string sizes are defined relative to the default font size which is specified by

• font.size - the default font size for text, given in pts. 10 pt is the standard value

Additionally, the weight can be specified (though only for the default it appears) by

• font.weight - The default weight of the font used by text.Text. Accepts {100, 200, 300, 400, 500, 600, 700, 800, 900} or 'normal' (400), 'bold' (700), 'lighter', and 'bolder' (relative with respect to current weight).

You can do that with

find . -mtime 0

From man find:

[The] time since each file was last modified is divided by 24 hours and any remainder is discarded. That means that to match -mtime 0, a file will have to have a modification in the past which is less than 24 hours ago.

I ran into this annoying issue with the Play framework. It would be nice if there was some way of knowing what build errors Eclipse is unhappy about, but it's not going to tell you. With one project, I was able to close the project, rebuild the Eclipse configuration with sbt eclipse, and reopen. With an almost identical project, that didn't work. But deleting the project, rebuilding the Eclipse configuration with sbt eclipse, and importing, did the trick.

I have faced the same issue while fetching elements using jQuery and data-* attribute.

so for your reference the shortest code is here:

This is my HTML Code:

<section data-js="carousel"></section>
<section></section>
<section></section>
<section data-js="carousel"></section>

This is my jQuery selector:

$('section[data-js="carousel"]');
// this will return array of the section elements which has data-js="carousel" attribute.

Not sure if it is a best practice, but when working with large amounts of images in a loop (i.e. creating and disposing a lot of Graphics/Image/Bitmap objects), i regularly let the GC.Collect.

I think I read somewhere that the GC only runs when the program is (mostly) idle, and not in the middle of a intensive loop, so that could look like an area where manual GC could make sense.

A fancy way to solve it is by using twice "rev" and "cut":

find ./ -name "*.txt" | rev | cut -d '/' -f1 | rev

I have created step by step instructions on how to do this as I also was very confused about how to get this working.

How to make a self extracting archive that runs your setup.exe with 7zip -sfx switch

Here are the steps.

Step 1 - Setup your installation folder

To make this easy create a folder c:\Install. This is where we will copy all the required files.

Step 2 - 7Zip your installers

1. Go to the folder that has your .msi and your setup.exe
2. Select both the .msi and the setup.exe
3. Right-Click and choose 7Zip --> "Add to Archive"
4. Name your archive "Installer.7z" (or a name of your choice)
5. Click Ok
6. You should now have "Installer.7z".
7. Copy this .7z file to your c:\Install directory

Step 3 - Get the 7z-Extra sfx extension module

You need to download 7zSD.sfx

1. Download one of the LZMA packages from here
2. Extract the package and find 7zSD.sfx in the bin folder.
3. Copy the file "7zSD.sfx" to c:\Install

Step 4 - Setup your config.txt

I would recommend using NotePad++ to edit this text file as you will need to encode in UTF-8, the following instructions are using notepad++.

1. Using windows explorer go to c:\Install
2. right-click and choose "New Text File" and name it config.txt
3. right-click and choose "Edit with NotePad++
4. Click the "Encoding Menu" and choose "Encode in UTF-8"

5. Enter something like this:

   ;!@Install@!UTF-8!
   Title="SOFTWARE v1.0.0.0"
   BeginPrompt="Do you want to install SOFTWARE v1.0.0.0?"
   RunProgram="setup.exe"
   ;!@InstallEnd@!
   

Edit this replacing [SOFTWARE v1.0.0.0] with your product name. Notes on the parameters and options for the setup file are here.

CheckPoint

You should now have a folder "c:\Install" with the following 3 files:

1. Installer.7z
2. 7zSD.sfx
3. config.txt

Step 5 - Create the archive

These instructions I found on the web but nowhere did it explain any of the 4 steps above.

1. Open a cmd window, Window + R --> cmd --> press enter

2. In the command window type the following

   cd \
   cd Install
   copy /b 7zSD.sfx + config.txt + Installer.7z MyInstaller.exe
   

3. Look in c:\Install and you will now see you have a MyInstaller.exe

You are finished

Run the installer

Double click on MyInstaller.exe and it will prompt with your message. Click OK and the setup.exe will run.

P.S. Note on Automation

Now that you have this working in your c:\Install directory I would create an "Install.bat" file and put the copy script in it.

copy /b 7zSD.sfx + config.txt + Installer.7z MyInstaller.exe

Now you can just edit and run the Install.bat every time you need to rebuild a new version of you deployment package.

You can use exec for that:

>>> foo = "bar"
>>> exec(foo + " = 'something else'")
>>> print bar
something else
>>> 

Read five lines each time, just put your statement in if statement , thats it

        String str1 = @"C:\Users\TEMP\Desktop\StaN.txt";   

        System.IO.StreamReader file = new System.IO.StreamReader(str1);

        line = file.ReadLine();

        Int32 ctn=0;

        try
        {

            while ((line = file.ReadLine()) != null)
            {

                    if (Counter == ctn)
                    {
                        MessageBox.Show("I am here");
                        ctn=ctn+5;
                        continue;
                    }
                    else
                    {
                        Counter++;
                        //MessageBox.Show(Counter.ToString());
                        MessageBox.Show(line.ToString());
                    } 
                }

            file.Close();
        }
        catch (Exception er)
        {

        }

mysqli_select_db() should have 2 parameters, the connection link and the database name -

mysqli_select_db($con, 'phpcadet') or die(mysqli_error($con));

Using mysqli_error in the die statement will tell you exactly what is wrong as opposed to a generic error message.

To get one cell value based on entire row selection:

if (dataGridView1.SelectedRows.Count > 0)
      {
         foreach (DataGridViewRow row in dataGridView1.Rows)
           {
               TextBox1.Text = row.Cells["ColumnName"].Value.ToString();
           }
      }
else
      {
        MessageBox.Show("Please select item!");
      }
     }

Just try this out:

Works perfect for me with zooming and mouse movement.. you can customize it to mouse wheel up & down Njoy!!!

Here is fiddle for this Fiddle

You can use CSS to do it for example

<style>
html{
    width:100%;
    height:100%;
}
body{
    width:100%;
    height:100%;
    background-color:#DDD;
}
</style>

For Scalar Function Syntax is

Select dbo.Function_Name(parameter_name)

Select dbo.Department_Employee_Count('HR')

List the packages by:

adb shell su 0 pm list packages

Review which package you want to uninstall and copy the package name from there. For example:

com.android.calculator2

Lastly type in:

adb uninstall com.android.calculator2 

and you are done.

Remove the project from the server from the Server View. Then run the project under the same server.

The problem is as @BalusC told corrupt of server.xml of tomcat which is configured in the eclipse. So when you do the above process server.xml will be recreated .

The simplest way to remove inner html elements and return only text would the JQuery .text() function.

Example:

var text = $('<p>A nice house was found in <b>Toronto</b></p>');

alert( text.html() );
//Outputs A nice house was found in <b>Toronto</b>

alert( text.text() );
////Outputs A nice house was found in Toronto

jsFiddle Demo

Because of your date format, you can use this code:

if(parseInt(first.replace(/-/g,""),10) > parseInt(second.replace(/-/g,""),10)){
   //...
}

It will check whether 20121121 number is bigger than 20121103 or not.

This function is generic function for every type of info. It counts the occurrence of the elements and then returns array with maximum occurring elements.

function mode () {
  var arr = [].slice.call(arguments);
  if ((args.length == 1) && (typeof args[0] === "object")) {
    args = args[0].mode();
  }

  var obj = {};
  for(var i = 0; i < arr.length; i++) {
    if(obj[arr[i]] === undefined) obj[arr[i]] = 1;
    else obj[arr[i]]++;
  }

  var max = 0;
  for (w in obj) {
    if (obj[w] > max) max = obj[w];
  }

  ret_val = [];
  for (w in obj) {
    if (obj[w] == max) ret_val.push(w);
  }

  return ret_val;
}

you can also use just like this in newer version of sql,

select year('2001-02-16 20:38:40') as year,
month('2001-02-16 20:38:40') as month,
day('2001-02-16 20:38:40') as day,
hour('2001-02-16 20:38:40') as hour,
minute('2001-02-16 20:38:40') as minute

Ok, The Windows 10 BatchFile is done works just like I had hoped. First press the windows key and R. Type mmc and Enter. In File Add SnapIn>Got to a specific Website and add it to the list. Press OK in the tab, and on the left side console root menu double click your site. Once it opens Add it to favourites. That should place it in C:\Users\user\AppData\Roaming\Microsoft\StartMenu\Programs\Windows Administrative Tools. I made a shortcut of this to a folder on the desktop. Right click the Shortcut and view the properties. In the Shortcut tab of the Properties click advanced and check the Run as Administrator. The Start in Location is also on the Shortcuts Tab you can add that to your batch file if you need. The Batch I made is as follows

@echo off
title Manage SiteEnviro
color 0a
:Clock
cls
echo Date:%date% Time:%time%
pause
cls
c:\WINDOWS\System32\netstat
c:\WINDOWS\System32\netstat -an
goto Greeting

:Greeting
cls
echo Open ShellSite
pause
cls
goto Manage SiteEnviro

:Manage SiteEnviro
"C:\Users\user\AppData\Roaming\Microsoft\Start Menu\Programs\Administrative Tools\YourCustomSavedMMC.msc"

You need to make a shortcut when you save this as a bat file and in the properties>shortcuts>advanced enable administrator access, can also set a keybind there and change the icon if you like. I probably did not need :Clock. The netstat commands can change to setting a hosted network or anything you want including nothing. Can Canscade websites in 1 mmc console and have more than 1 favourite added into the batch file.

You can embed HTML in Markdown, so you can do something like this:

<img style="float: right;" src="whatever.jpg">

Continue markdown text...

Simply use

ax.set_xticklabels(label_list, rotation=45)

I know this is an old post but its relevant to what I'm working on currently.

What I'm aiming to do is create next/previous page buttons at the top of a html page, and say I'm on 'book.html', with the current 'display' ID content being 'page-1.html' through ajax, if i click the 'next' button it will load 'page-2.html' through ajax, WITHOUT reloading the page.

How would I go about doing this through AJAX as I have seen many examples but most of them are completely different, and most examples of using AJAX are for WordPress forms and stuff.

Currently using the below line will open the entire page, I want to know the best way to go about using AJAX instead if possible :) window.location(url);

I'm incorportating the below code as an example:

var i = 1;
var url = "pages/page-" + i + ".html";

    function incPage() {
    if (i < 10) {
        i++;
        window.location = url; 
        //load next page in body using AJAX request

    } else if (i = 10) {
        i = 0;
    }
    document.getElementById("display").innerHTML = i;
}

function decPage() {
    if (i > 0) {
        --i;
        window.location = url; 
        //load previous page in body using AJAX request
    } else if (i = 0) {
        i = 10;
    }
    document.getElementById("display").innerHTML = i;
}

The issue is with this line

 xlo.Worksheets(1).Cells(2, 2) = TextBox1.Text

You have the textbox defined at some other location which you are not using here. Excel is unable to find the textbox object in the current sheet while this textbox was defined in xlw.

Hence replace this with

 xlo.Worksheets(1).Cells(2, 2) = worksheets("xlw").TextBox1.Text 

The simple method is to share the mysql unix socket to host machine. Then connect through the socket

Steps:

• Create shared folder for host machine eg: mkdir /host
• Run docker container with volume mount option docker run -it -v /host:/shared <mysql image>.
• Then change mysql configuration file /etc/my.cnf and change socket entry in the file to socket=/shared/mysql.sock
• Restart MySQL service service mysql restart in docker

If you were like me, running maven compile deploy from eclipse's maven run configuration, the issue could be related to eclipse's own embedded maven as described in https://bugs.eclipse.org/bugs/show_bug.cgi?id=562847

The workaround is to run mvn compile deploy from CLI such as bash, or to NOT use embedded maven in the eclipse's maven run configuration, and add an external maven (mine is in /usr/share/mvn), and voila, it'll say BUILD SUCCESS.

The input type=email page of the www.w3.org site notes that an email address is any string which matches the following regular expression:

/^[a-zA-Z0-9.!#$%&’*+/=?^_`{|}~-]+@[a-zA-Z0-9-]+(?:\.[a-zA-Z0-9-]+)*$/

Use the required attribute and a pattern attribute to require the value to match the regex pattern.

<input
    type="text"
    pattern="/^[a-zA-Z0-9.!#$%&’*+/=?^_`{|}~-]+@[a-zA-Z0-9-]+(?:\.[a-zA-Z0-9-]+)*$/"

The padding options padx and pady of the grid and pack methods can take a 2-tuple that represent the left/right and top/bottom padding.

Here's an example:

import tkinter as tk

class MyApp():
    def __init__(self):
        self.root = tk.Tk()
        l1 = tk.Label(self.root, text="Hello")
        l2 = tk.Label(self.root, text="World")
        l1.grid(row=0, column=0, padx=(100, 10))
        l2.grid(row=1, column=0, padx=(10, 100)) 

app = MyApp()
app.root.mainloop()

Using jQuery you can use contents(). For example:

var inside = $('#one').contents();

You're currently trying to remove the exact string [] - two square brackets with nothing between them. Instead, you want to remove all [ and separately remove all ].

Personally I would avoid using replaceAll here as it introduces more confusion due to the regex part - I'd use:

String replaced = original.replace("[", "").replace("]", "");

Only use the methods which take regular expressions if you really want to do full pattern matching. When you just want to replace all occurrences of a fixed string, replace is simpler to read and understand.

(There are alternative approaches which use the regular expression form and really match patterns, but I think the above code is significantly simpler.)

Try this:

public static boolean jsonsEqual(Object obj1, Object obj2) throws JSONException

    {
        if (!obj1.getClass().equals(obj2.getClass()))
        {
            return false;
        }

        if (obj1 instanceof JSONObject)
        {
            JSONObject jsonObj1 = (JSONObject) obj1;

            JSONObject jsonObj2 = (JSONObject) obj2;

            String[] names = JSONObject.getNames(jsonObj1);
            String[] names2 = JSONObject.getNames(jsonObj1);
            if (names.length != names2.length)
            {
                return false;
            }

            for (String fieldName:names)
            {
                Object obj1FieldValue = jsonObj1.get(fieldName);

                Object obj2FieldValue = jsonObj2.get(fieldName);

                if (!jsonsEqual(obj1FieldValue, obj2FieldValue))
                {
                    return false;
                }
            }
        }
        else if (obj1 instanceof JSONArray)
        {
            JSONArray obj1Array = (JSONArray) obj1;
            JSONArray obj2Array = (JSONArray) obj2;

            if (obj1Array.length() != obj2Array.length())
            {
                return false;
            }

            for (int i = 0; i < obj1Array.length(); i++)
            {
                boolean matchFound = false;

                for (int j = 0; j < obj2Array.length(); j++)
                {
                    if (jsonsEqual(obj1Array.get(i), obj2Array.get(j)))
                    {
                        matchFound = true;
                        break;
                    }
                }

                if (!matchFound)
                {
                    return false;
                }
            }
        }
        else
        {
            if (!obj1.equals(obj2))
            {
                return false;
            }
        }

        return true;
    }

I also face this problem recently on chrome. I just give absolute path to my CSS file problem solve.

<link rel="stylesheet" href="<?=SS_URL?>arica/style.css" type="text/css" />

you can use

date -d "30 days ago" +"%d/%m/%Y"

to get the date from 30 days ago, similarly you can replace 30 with x amount of days

Technically, you can use StackTrace, but this is very slow and will not give you the answers you expect a lot of the time. This is because during release builds optimizations can occur that will remove certain method calls. Hence you can't be sure in release whether stacktrace is "correct" or not.

Really, there isn't any foolproof or fast way of doing this in C#. You should really be asking yourself why you need this and how you can architect your application, so you can do what you want without knowing which method called it.

The ENOSPC ("No space left on device") error will be triggered in any situation in which the data or the metadata associated with an I/O operation can't be written down anywhere because of lack of space. This doesn't always mean disk space – it could mean physical disk space, logical space (e.g. maximum file length), space in a certain data structure or address space. For example you can get it if there isn't space in the directory table (vfat) or there aren't any inodes left. It roughly means “I can't find where to write this down”.

Particularly in Python, this can happen on any write I/O operation. It can happen during f.write, but it can also happen on open, on f.flush and even on f.close. Where it happened provides a vital clue for the reason that it did – if it happened on open there wasn't enough space to write the metadata for the entry, if it happened during f.write, f.flush or f.close there wasn't enough disk space left or you've exceeded the maximum file size.

If the filesystem in the given directory is vfat you'd hit the maximum file limit at about the same time that you did. The limit is supposed to be 2^16 directory entries, but if I recall correctly some other factors can affect it (e.g. some files require more than one entry).

It would be best to avoid creating so many files in a directory. Few filesystems handle so many directory entries with ease. Unless you're certain that your filesystem deals well with many files in a directory, you can consider another strategy (e.g. create more directories).

P.S. Also do not trust the remaining disk space – some file systems reserve some space for root and others miscalculate the free space and give you a number that just isn't true.

@Jason is correct in a way but not entirely.

update

Update the registered submodules, i.e. clone missing submodules and checkout the commit specified in the index of the containing repository. This will make the submodules HEAD be detached unless --rebase or --merge is specified or the key submodule.$name.update is set to rebase or merge.

So, git submodule update does checkout, but it is to the commit in the index of the containing repository. It does not yet know of the new commit upstream at all. So go to your submodule, get the commit you want and commit the updated submodule state in the main repository and then do the git submodule update.

Seems like a Permissions Issue. I was facing the same error. But when I ran it from the root account, it worked. So either give the read permission to the file using chmod (in linux) or run your script after logging in as a root user.

On the last entry; this is another trick:

SELECT AUTO_INCREMENT FROM information_schema.tables WHERE table_schema = ... and table_name = ...

String message = "This is testing."
Intent shareText = new Intent(Intent.ACTION_SEND);
shareText .setType("text/plain");
shareText .putExtra(Intent.EXTRA_TEXT, message);

startActivity(Intent.createChooser(shareText , "Title of the dialog the system will open"));

The best solution is to reconfigure the XAMPP Apache server to listen and use different port numbers. Here is how you do it:

1) First, you need to open the Apache “httpd.conf” file and configure it to use/listen on a new port no. To open httpd.conf file, click the “Config” button next to Apache “Start” and “Admin” buttons. In the popup menu that opens, click and open httpd.conf

2) Within the httpd.conf file search for “listen”. You’ll find two rows with something like:

#Listen 12.34.56.78:80
Listen 80

Change the port no to a port no. of your choice (e.g. port 1234) like below

#Listen 12.34.56.78:1234
Listen 1234

3) Next, in the same httpd.conf file look for “ServerName localhost:” Set it to the new port no.

ServerName localhost:1234

4) Save and close the httpd.conf file.

5) Now click the Apache config button again and open the “httpd-ssl.conf” file.

6) In the httpd-ssl.conf file, look for “Listen” again. You may find:

Listen 443

Change it to listen on a new port no of your choice. Say like:

Listen 1443

7) In the same httpd-ssl.conf file find another line that says <VirtualHost _default_:443>. Change this to your new port no. (like 1443)

8) Also in the same httpd-ssl.conf you can find another line defining the port no. For that look for “ServerName”. you might find something like:

ServerName www.example.com:443 or  ServerName localhost:433

Change this ServerName to your new port no.

8) Save and close the httpd-ssl.conf file.

9) Finally, there’s just one more place you should change the port no. For that, click and open the “Config” button of your XAMPP Control Panel. Then click the, “Service and Port Settings” button. Within it, click the “Apache” tab and enter and save the new port nos in the “main port” and “SSL port” boxes. Click save and close the config boxes.

That should do the trick. Now “Start” Apache and if everything goes well, your Apache server should start up.

You will also see the Apache Port/s no in the XAMPP control panel has change to the new port IDs you set.

Just as an alternative that I could wrap my head around much easier:

data = load_iris()
df = pd.DataFrame(data['data'], columns=data['feature_names'])
df['target'] = data['target']
df.head()

Basically instead of concatenating from the get go, just make a data frame with the matrix of features and then just add the target column with data['whatvername'] and grab the target values from the dataset

This is a bug in the npm package regarding dependencies : https://askubuntu.com/questions/1088662/npm-depends-node-gyp-0-10-9-but-it-is-not-going-to-be-installed

Bugs have been reported. The above may not work depending what you have installed already, at least it didn't for me on an up to date Ubuntu 18.04 LTS.

I followed the suggested dependencies and installed them as the above link suggests:

and then

sudo apt-get install npm

1. Make sure session_start(); is called before any sessions are being called. So a safe bet would be to put it at the beginning of your page, immediately after the opening <?php tag before anything else. Also ensure there are no whitespaces/tabs before the opening <?php tag.
2. After the header redirect, end the current script using exit(); (Others have also suggested session_write_close(); and session_regenerate_id(true), you can try those as well, but I'd use exit();).
3. Make sure cookies are enabled in the browser you are using to test it on.
4. Ensure register_globals is off, you can check this on the php.ini file and also using phpinfo(). Refer to this as to how to turn it off.
5. Make sure you didn't delete or empty the session.
6. Make sure the key in your $_SESSION superglobal array is not overwritten anywhere.
7. Make sure you redirect to the same domain. So redirecting from a www.yourdomain.com to yourdomain.com doesn't carry the session forward.
8. Make sure your file extension is .php (it happens!).

Just as an assist if you go with Android Studio 0.4.x offline mode (because this thread is one of the main ones that google throws up when querying this issue).

I solved a similar problem by creating an entirely new project and "Checking out from Version Control" Merging the two projects later was fairly easy.

"... current system status (current CPU, RAM, free disk space, etc.)" And "*nix and Windows platforms" can be a difficult combination to achieve.

The operating systems are fundamentally different in the way they manage these resources. Indeed, they differ in core concepts like defining what counts as system and what counts as application time.

"Free disk space"? What counts as "disk space?" All partitions of all devices? What about foreign partitions in a multi-boot environment?

I don't think there's a clear enough consensus between Windows and *nix that makes this possible. Indeed, there may not even be any consensus between the various operating systems called Windows. Is there a single Windows API that works for both XP and Vista?

if you use the git for mac in GUI you can chose Respository->Pull or the "comm+shift+p" to "git pull" first, then publish the source.

You can use a named function on the constructor.

MyClass1 = function foo(id, member) {
    this.id = id;
    this.member = member;
}

var myobject = new MyClass1("5678999", "text");

console.log( myobject.constructor );

//function foo(id, member) {
//    this.id = id;
//    this.member = member;
//}

You could use a regex to parse out 'foo' from myobject.constructor and use that to get the name.

    void SiftDown(int n)
    {
        var v = heap[n];
        for (var n2 = n * 2; n2 < Count; n = n2, n2 *= 2)

            if (n2 + 1 < Count && comparer.Compare(heap[n2 + 1], heap[n2]) > 0) n2++;
            if (comparer.Compare(v, heap[n2]) >= 0) break;
            heap[n] = heap[n2];
        }
        heap[n] = v;
    }
}

easy.

To do this for oracle sql, the syntax would be:

I ran into this error sporadically and could not understand. Googling did not help.

I finally found out. I run a couple of docker containers, among them NGINX and Apache. The command at hand addresses a specific container, running Apache. As it turned out, I also have a cron job doing some heavy lifting at times running on the same container. Depending on the load this cron job puts on this container, it was not able to answer my command in a timely manner, resulting in error 52 empty reply from server or even 502 Bad Gateway.

I discovered and verified this by plain curl when I noticed that the process I investigated took less than 2 seconds and all of a sudden I got a 52 error and then a 502 error and then again less than 2 seconds - so it was definitely not my code which was unchanged. Using ps aux within the container I saw the other process running and understood.

Actually, I was bothered by 502 Bad Gateway from NGINX with long running jobs and could not fix it with the appropriate parameters, so I finally gave up and switched these things to Apache. That's why I was puzzled even more about these errors.

The remedy is simple. I just fired up some more instances of this container with docker service scale and that was it. docker load balances on its own.

Well, there is more to this as another example showed. This time I did some repetitious jobs.

I found out that after some time I ran out of memory used by PHP which cannot be reclaimed, so the process died.

Why? Having more than a dozen containers on a 8GB RAM machine, I initially thought it would be a good idea to limit RAM usage on PHP containers to 50MB.

Stupid! I forgot about it, but swarmpit gave me a hint. I call ini_set("memory_limit",-1); in the constructor of my class, but that only went as far as those 50MB.

So I removed those restrictions from my compose file. Now those containers may use up to 8GB. The process runs with Apache for hours now and it looks like the problem is solved, memory usage rising to well beyond 100MB.

Another caveat: To easily get and read debug messages, I started said process in Opera under Windows. That is fine with errors appearing soon.

However, if the last one is cared for, quite naturally the process runs and runs and memory usage in the browser builds up, eventually making my local machine unusable. So if that happens, kill this tab and the process keeps running fine.

I think that you should use this code :-)

    // sample string
            const param= "Hi you know anybody like pizaa";

         // You can change limit parameter(up to you)
         const checkTitle = (str, limit = 17) => {
      var newTitle = [];
      if (param.length >= limit) {
        param.split(" ").reduce((acc, cur) => {
          if (acc + cur.length <= limit) {
            newTitle.push(cur);
          }
          return acc + cur.length;
        }, 0);
        return `${newTitle.join(" ")} ...`;
      }
      return param;
    };
    console.log(checkTitle(str));

// result : Hi you know anybody ...

In answer to your first question, it should be as simple as replacing:

   when(LoggerFactory.getLogger(GoodbyeController.class)).thenReturn(loggerMock);

with

   when(LoggerFactory.getLogger(any(Class.class))).thenReturn(loggerMock);

Regarding your second question (and possibly the puzzling behavior with the first), I think the problem is that logger is static. So,

private static Logger logger = LoggerFactory.getLogger(GoodbyeController.class);

is executed when the class is initialized, not the when the object is instantiated. Sometimes this can be at about the same time, so you'll be OK, but it's hard to guarantee that. So you set up LoggerFactory.getLogger to return your mock, but the logger variable may have already been set with a real Logger object by the time your mocks are set up.

You may be able to set the logger explicitly using something like ReflectionTestUtils (I don't know if that works with static fields) or change it from a static field to an instance field. Either way, you don't need to mock LoggerFactory.getLogger because you'll be directly injecting the mock Logger instance.

If you run a the module task with android plugin 1.2.3 in module directory , the problem appears. Try this:

../gradlew -b ../build.gradle  -c ../settings.gradle  :module:xxx

There is no need for that, as you can use css 'writing-mode' with values 'vertical-lr' or 'vertical-rl' as desired.

.item {
  writing-mode: vertical-rl;
}

The correct way of using post variables is

<?php

$department = $_POST['department'];

?>

Use single quotation(')

Original answer

Yes, this is possible:

List<BigDecimal> bdList = new ArrayList<>();
//populate list
BigDecimal result = bdList.stream()
        .reduce(BigDecimal.ZERO, BigDecimal::add);

What it does is:

1. Obtain a List<BigDecimal>.
2. Turn it into a Stream<BigDecimal>

3. Call the reduce method.

   3.1. We supply an identity value for addition, namely BigDecimal.ZERO.

   3.2. We specify the BinaryOperator<BigDecimal>, which adds two BigDecimal's, via a method reference BigDecimal::add.

Updated answer, after edit

I see that you have added new data, therefore the new answer will become:

List<Invoice> invoiceList = new ArrayList<>();
//populate
Function<Invoice, BigDecimal> totalMapper = invoice -> invoice.getUnit_price().multiply(invoice.getQuantity());
BigDecimal result = invoiceList.stream()
        .map(totalMapper)
        .reduce(BigDecimal.ZERO, BigDecimal::add);

It is mostly the same, except that I have added a totalMapper variable, that has a function from Invoice to BigDecimal and returns the total price of that invoice.

Then I obtain a Stream<Invoice>, map it to a Stream<BigDecimal> and then reduce it to a BigDecimal.

Now, from an OOP design point I would advice you to also actually use the total() method, which you have already defined, then it even becomes easier:

List<Invoice> invoiceList = new ArrayList<>();
//populate
BigDecimal result = invoiceList.stream()
        .map(Invoice::total)
        .reduce(BigDecimal.ZERO, BigDecimal::add);

Here we directly use the method reference in the map method.

__repr__ is used by the standalone Python interpreter to display a class in printable format. Example:

~> python3.5
Python 3.5.1 (v3.5.1:37a07cee5969, Dec  5 2015, 21:12:44) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> class StackOverflowDemo:
...     def __init__(self):
...         pass
...     def __repr__(self):
...         return '<StackOverflow demo object __repr__>'
... 
>>> demo = StackOverflowDemo()
>>> demo
<StackOverflow demo object __repr__>

In cases where a __str__ method is not defined in the class, it will call the __repr__ function in an attempt to create a printable representation.

>>> str(demo)
'<StackOverflow demo object __repr__>'

Additionally, print()ing the class will call __str__ by default.

I had this problem because I configured my WCF Service to return a System.Data.DataTable.

It worked fine in my test HTML page, but blew up when I put this in my Windows Form application.

I had to go in and change the Service's Operational Contract signature from DataTable to DataSet and return the data accordingly.

If you have this problem, you may want to add an additional Operational Contract to your Service so you do not have to worry about breaking code that rely on existing Services.

You need to add a '/' after the dir name

Well, I'm not sure that merge would be the way to go. Personally I would build a new data frame by creating an index of the dates and then constructing the columns using list comprehensions. Possibly not the most pythonic way, but it seems to work for me!

import pandas as pd
import numpy as np

df1 = pd.DataFrame(np.random.randn(5,3), index=pd.date_range('01/02/2014',periods=5,freq='D'), columns=['a','b','c'] )

The execution says it's putting the jacoco data in /Users/davea/Dropbox/workspace/myproject/target/jacoco.exec but your maven configuration is looking for the data in ${basedir}/target/coverage-reports/jacoco-unit.exec.

mayby one little change from the top answer, because DB_NAME() returns always content db of execution. so, for me better like below:

sp_MSforeachdb 'select DB_name(db_id(''?'')) as DB, * From ?..sysobjects where xtype in (''U'', ''P'') And name like ''[_]x[_]%'''

In my case I was looking for tables their names started with _x_

You should be able to do the following:

$params = @{"@type"="login";
 "username"="[email protected]";
 "password"="yyy";
}

Invoke-WebRequest -Uri http://foobar.com/endpoint -Method POST -Body $params

This will send the post as the body. However - if you want to post this as a Json you might want to be explicit. To post this as a JSON you can specify the ContentType and convert the body to Json by using

Invoke-WebRequest -Uri http://foobar.com/endpoint -Method POST -Body ($params|ConvertTo-Json) -ContentType "application/json"

Extra: You can also use the Invoke-RestMethod for dealing with JSON and REST apis (which will save you some extra lines for de-serializing)

I advise you to go with Scanner instead of DataInputStream. Scanner is specifically designed for this purpose and introduced in Java 5. See the following links to know how to use Scanner.

• Java Documentation
• Java Tutorial

Example

Scanner s = new Scanner(System.in);
System.out.println(s.nextInt());
System.out.println(s.nextInt());
System.out.println(s.next());
System.out.println(s.next());

You can try the c++ open source project WinRobot @git, a powerful screen capturer

CComPtr<IWinRobotService> pService;
hr = pService.CoCreateInstance(__uuidof(ServiceHost) );

//get active console session
CComPtr<IUnknown> pUnk;
hr = pService->GetActiveConsoleSession(&pUnk);
CComQIPtr<IWinRobotSession> pSession = pUnk;

// capture screen
pUnk = 0;
hr = pSession->CreateScreenCapture(0,0,1280,800,&pUnk);

// get screen image data(with file mapping)
CComQIPtr<IScreenBufferStream> pBuffer = pUnk;

Support :

• UAC Window
• Winlogon
• DirectShowOverlay

I you have the char '9', it will store its ASCII code, so to get the int value, you have 2 ways

char x = '9';
int y = Character.getNumericValue(x);   //use a existing function
System.out.println(y + " " + (y + 1));  // 9  10

or

char x = '9';
int y = x - '0';                        // substract '0' code to get the difference
System.out.println(y + " " + (y + 1));  // 9  10

And it fact, this works also :

char x = 9;
System.out.println(">" + x + "<");     //>  < prints a horizontal tab
int y = (int) x;
System.out.println(y + " " + (y + 1)); //9 10

You store the 9 code, which corresponds to a horizontal tab (you can see when print as String, bu you can also use it as int as you see above

As I mentioned in this answer, if the server runs on a port other than 80 (as might be common on a development/intranet machine) then HTTP_HOST contains the port, while SERVER_NAME does not.

$_SERVER['HTTP_HOST'] == 'localhost:8080'
$_SERVER['SERVER_NAME'] == 'localhost'

(At least that's what I've noticed in Apache port-based virtualhosts)

Note that HTTP_HOST does not contain :443 when running on HTTPS (unless you're running on a non-standard port, which I haven't tested).

As others have noted, the two also differ when using IPv6:

$_SERVER['HTTP_HOST'] == '[::1]'
$_SERVER['SERVER_NAME'] == '::1'

Declare the a element as display: inline-block and drop the width and height from the li element.

Alternatively, apply a float: left to the li element and use display: block on the a element. This is a bit more cross browser compatible, as display: inline-block is not supported in Firefox <= 2 for example.

The first method allows you to have a dynamically centered list if you give the ul element a width of 100% (so that it spans from left to right edge) and then apply text-align: center.

Use line-height to control the text's Y-position inside the element.

You could try csync, it is the sync engine under the hood of owncloud.

You can generate the XML documentation file using either the command-line compiler or through the Visual Studio interface. If you are compiling with the command-line compiler, use options /doc or /doc+. That will generate an XML file by the same name and in the same path as the assembly. To specify a different file name, use /doc:file.

If you are using the Visual Studio interface, there's a setting that controls whether the XML documentation file is generated. To set it, double-click My Project in Solution Explorer to open the Project Designer. Navigate to the Compile tab. Find "Generate XML documentation file" at the bottom of the window, and make sure it is checked. By default this setting is on. It generates an XML file using the same name and path as the assembly.

In the action method of the request to the url "http://localhost:85458/api/ctrl/"

var baseUrl = Request.RequestUri.GetLeftPart(UriPartial.Authority) ;

this will get you http://localhost:85458

All your exercise conditionals are separate and the else is only tied to the last if statement. Use else if to bind them all together in the way I believe you intend.

Make sure the file names do not contain special characters such as ñ for example

This is the best way to get a schema dynamically and add it to the different tables within a database in order to get other information dynamically

exec (@sql)

of course #tables is a dynamic table in the stored procedure

It is a way of making a link do absolutely nothing when clicked (unless Javascript events are bound to it).

It is a way of running Javascript instead of following a link:

<a href="Javascript: doStuff();">link</a>

When there isn't actually javascript to run (like your example) it does nothing.

You need to specify the master for the second button. Otherwise it will get packed onto the first window. This is needed not only for Button, but also for other widgets and non-gui objects such as StringVar.

Quick fix: add the frame new as the first argument to your Button in Demo2.

Possibly better: Currently you have Demo2 inheriting from tk.Frame but I think this makes more sense if you change Demo2 to be something like this,

class Demo2(tk.Toplevel):     
    def __init__(self):
        tk.Toplevel.__init__(self)
        self.title("Demo 2")
        self.button = tk.Button(self, text="Button 2", # specified self as master
                                width=25, command=self.close_window)
        self.button.pack()

    def close_window(self):
        self.destroy()

Just as a suggestion, you should only import tkinter once. Pick one of your first two import statements.

You could also use CSS pseudo elements to pick and display your labels from all your checkbox's value attributes (respectively).
Edit: This will only work with webkit and blink based browsers (Chrome(ium), Safari, Opera....) and thus most mobile browsers. No Firefox or IE support here.
This may only be useful when embedding webkit/blink onto your apps.

<input type="checkbox" value="My checkbox label value" />
<style>
[type=checkbox]:after {
    content: attr(value);
    margin: -3px 15px;
    vertical-align: top;
    white-space:nowrap;
    display: inline-block;
}
</style>

All pseudo element labels will be clickable.

Use jquery animate and give it a long duration say 2000

$("#Friends").animate({ 
        top: "-=30px",
      }, duration );

The -= means that the animation will be relative to the current top position.

Note that the Friends element must have position set to relative in the css:

#Friends{position:relative;}

With JUnit5 I think the best way is to @ExtendWith(MockitoExtension.class) with @Mock in the method parameter or the field.

Short form:

.zip is an archive format using, usually, the Deflate compression method. The .gz gzip format is for single files, also using the Deflate compression method. Often gzip is used in combination with tar to make a compressed archive format, .tar.gz. The zlib library provides Deflate compression and decompression code for use by zip, gzip, png (which uses the zlib wrapper on deflate data), and many other applications.

Long form:

The ZIP format was developed by Phil Katz as an open format with an open specification, where his implementation, PKZIP, was shareware. It is an archive format that stores files and their directory structure, where each file is individually compressed. The file type is .zip. The files, as well as the directory structure, can optionally be encrypted.

The ZIP format supports several compression methods:

    0 - The file is stored (no compression)
    1 - The file is Shrunk
    2 - The file is Reduced with compression factor 1
    3 - The file is Reduced with compression factor 2
    4 - The file is Reduced with compression factor 3
    5 - The file is Reduced with compression factor 4
    6 - The file is Imploded
    7 - Reserved for Tokenizing compression algorithm
    8 - The file is Deflated
    9 - Enhanced Deflating using Deflate64(tm)
   10 - PKWARE Data Compression Library Imploding (old IBM TERSE)
   11 - Reserved by PKWARE
   12 - File is compressed using BZIP2 algorithm
   13 - Reserved by PKWARE
   14 - LZMA
   15 - Reserved by PKWARE
   16 - IBM z/OS CMPSC Compression
   17 - Reserved by PKWARE
   18 - File is compressed using IBM TERSE (new)
   19 - IBM LZ77 z Architecture 
   20 - deprecated (use method 93 for zstd)
   93 - Zstandard (zstd) Compression 
   94 - MP3 Compression 
   95 - XZ Compression 
   96 - JPEG variant
   97 - WavPack compressed data
   98 - PPMd version I, Rev 1
   99 - AE-x encryption marker (see APPENDIX E)

Methods 1 to 7 are historical and are not in use. Methods 9 through 98 are relatively recent additions and are in varying, small amounts of use. The only method in truly widespread use in the ZIP format is method 8, Deflate, and to some smaller extent method 0, which is no compression at all. Virtually every .zip file that you will come across in the wild will use exclusively methods 8 and 0, likely just method 8. (Method 8 also has a means to effectively store the data with no compression and relatively little expansion, and Method 0 cannot be streamed whereas Method 8 can be.)

The ISO/IEC 21320-1:2015 standard for file containers is a restricted zip format, such as used in Java archive files (.jar), Office Open XML files (Microsoft Office .docx, .xlsx, .pptx), Office Document Format files (.odt, .ods, .odp), and EPUB files (.epub). That standard limits the compression methods to 0 and 8, as well as other constraints such as no encryption or signatures.

Around 1990, the Info-ZIP group wrote portable, free, open-source implementations of zip and unzip utilities, supporting compression with the Deflate format, and decompression of that and the earlier formats. This greatly expanded the use of the .zip format.

In the early '90s, the gzip format was developed as a replacement for the Unix compress utility, derived from the Deflate code in the Info-ZIP utilities. Unix compress was designed to compress a single file or stream, appending a .Z to the file name. compress uses the LZW compression algorithm, which at the time was under patent and its free use was in dispute by the patent holders. Though some specific implementations of Deflate were patented by Phil Katz, the format was not, and so it was possible to write a Deflate implementation that did not infringe on any patents. That implementation has not been so challenged in the last 20+ years. The Unix gzip utility was intended as a drop-in replacement for compress, and in fact is able to decompress compress-compressed data (assuming that you were able to parse that sentence). gzip appends a .gz to the file name. gzip uses the Deflate compressed data format, which compresses quite a bit better than Unix compress, has very fast decompression, and adds a CRC-32 as an integrity check for the data. The header format also permits the storage of more information than the compress format allowed, such as the original file name and the file modification time.

Though compress only compresses a single file, it was common to use the tar utility to create an archive of files, their attributes, and their directory structure into a single .tar file, and to then compress it with compress to make a .tar.Z file. In fact, the tar utility had and still has an option to do the compression at the same time, instead of having to pipe the output of tar to compress. This all carried forward to the gzip format, and tar has an option to compress directly to the .tar.gz format. The tar.gz format compresses better than the .zip approach, since the compression of a .tar can take advantage of redundancy across files, especially many small files. .tar.gz is the most common archive format in use on Unix due to its very high portability, but there are more effective compression methods in use as well, so you will often see .tar.bz2 and .tar.xz archives.

Unlike .tar, .zip has a central directory at the end, which provides a list of the contents. That and the separate compression provides random access to the individual entries in a .zip file. A .tar file would have to be decompressed and scanned from start to end in order to build a directory, which is how a .tar file is listed.

Shortly after the introduction of gzip, around the mid-1990s, the same patent dispute called into question the free use of the .gif image format, very widely used on bulletin boards and the World Wide Web (a new thing at the time). So a small group created the PNG losslessly compressed image format, with file type .png, to replace .gif. That format also uses the Deflate format for compression, which is applied after filters on the image data expose more of the redundancy. In order to promote widespread usage of the PNG format, two free code libraries were created. libpng and zlib. libpng handled all of the features of the PNG format, and zlib provided the compression and decompression code for use by libpng, as well as for other applications. zlib was adapted from the gzip code.

All of the mentioned patents have since expired.

The zlib library supports Deflate compression and decompression, and three kinds of wrapping around the deflate streams. Those are: no wrapping at all ("raw" deflate), zlib wrapping, which is used in the PNG format data blocks, and gzip wrapping, to provide gzip routines for the programmer. The main difference between zlib and gzip wrapping is that the zlib wrapping is more compact, six bytes vs. a minimum of 18 bytes for gzip, and the integrity check, Adler-32, runs faster than the CRC-32 that gzip uses. Raw deflate is used by programs that read and write the .zip format, which is another format that wraps around deflate compressed data.

zlib is now in wide use for data transmission and storage. For example, most HTTP transactions by servers and browsers compress and decompress the data using zlib, specifically HTTP header Content-Encoding: deflate means deflate compression method wrapped inside the zlib data format.

Different implementations of deflate can result in different compressed output for the same input data, as evidenced by the existence of selectable compression levels that allow trading off compression effectiveness for CPU time. zlib and PKZIP are not the only implementations of deflate compression and decompression. Both the 7-Zip archiving utility and Google's zopfli library have the ability to use much more CPU time than zlib in order to squeeze out the last few bits possible when using the deflate format, reducing compressed sizes by a few percent as compared to zlib's highest compression level. The pigz utility, a parallel implementation of gzip, includes the option to use zlib (compression levels 1-9) or zopfli (compression level 11), and somewhat mitigates the time impact of using zopfli by splitting the compression of large files over multiple processors and cores.

I had the same problem. I stash my changes with git stash and hard reset the branch in local to a previous commit(I thought it caused that) then did a git pull and I am not getting that head detached now. Dont forget git stash apply to have your changes again.

ul {
    list-style-type: none;    
}

ul li:before {
    content:'*'; /* Change this to unicode as needed*/
    width: 1em !important;
    margin-left: -1em;
    display: inline-block;
}

Use

"$filepath"_newstap.sh

or

${filepath}_newstap.sh

or

$filepath\_newstap.sh

_ is a valid character in identifiers. Dot is not, so the shell tried to interpolate $filepath_newstap.

You can use set -u to make the shell exit with an error when you reference an undefined variable.

The Makefile builds the hello executable if any one of main.cpp, hello.cpp, factorial.cpp changed. The smallest possible Makefile to achieve that specification could have been:

hello: main.cpp hello.cpp factorial.cpp
    g++ -o hello main.cpp hello.cpp factorial.cpp

• pro: very easy to read
• con: maintenance nightmare, duplication of the C++ dependencies
• con: efficiency problem, we recompile all C++ even if only one was changed

To improve on the above, we only compile those C++ files that were edited. Then, we just link the resultant object files together.

OBJECTS=main.o hello.o factorial.o

hello: $(OBJECTS)
    g++ -o hello $(OBJECTS)

main.o: main.cpp
    g++ -c main.cpp

hello.o: hello.cpp
    g++ -c hello.cpp

factorial.o: factorial.cpp
    g++ -c factorial.cpp

• pro: fixes efficiency issue
• con: new maintenance nightmare, potential typo on object files rules

To improve on this, we can replace all object file rules with a single .cpp.o rule:

OBJECTS=main.o hello.o factorial.o

hello: $(OBJECTS)
    g++ -o hello $(OBJECTS)

.cpp.o:
    g++ -c $< -o $@

• pro: back to having a short makefile, somewhat easy to read

Here the .cpp.o rule defines how to build anyfile.o from anyfile.cpp.

• $< matches to first dependency, in this case, anyfile.cpp
• $@ matches the target, in this case, anyfile.o.

The other changes present in the Makefile are:

• Making it easier to changes compilers from g++ to any C++ compiler.
• Making it easier to change the compiler options.
• Making it easier to change the linker options.
• Making it easier to change the C++ source files and output.
• Added a default rule 'all' which acts as a quick check to ensure all your source files are present before an attempt to build your application is made.

the solution here worked for me : https://community.hortonworks.com/articles/4427/fix-under-replicated-blocks-in-hdfs-manually.html

su - <$hdfs_user>

bash-4.1$ hdfs fsck / | grep 'Under replicated' | awk -F':' '{print $1}' >> /tmp/under_replicated_files 

-bash-4.1$ for hdfsfile in `cat /tmp/under_replicated_files`; do echo "Fixing $hdfsfile :" ;  hadoop fs -setrep 3 $hdfsfile; done

In your MakeFile or CMakeLists.txt you can set CMAKE_CXX_FLAGS as below:

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -I/path/to/your/folder")

First add a global variable

Context mContext;

Then change your constructor to this

public FeedAdapter(Context context, List<Post> myDataset) {
    mContext = context;
    mDataset = myDataset;
}

The pass your context when creating the adapter.

FeedAdapter myAdapter = new FeedAdapter(this,myDataset);

Kotlin:

var list=ArrayList<Your class name>()
val listresult: Array<YOUR CLASS NAME> = Gson().fromJson(
                YOUR JSON RESPONSE IN STRING,
                Array<Your class name>:: class.java)

list.addAll(listresult)

Use putty. Put install directory path in environment values (PATH), and restart your PC if required.

Open cmd (command prompt) and type

C:/> pscp "C:\Users/gsjha/Desktop/example.txt" user@host:/home/

It'll be copied to the system.

You can avoid the 100% width issue by specifying a maximum width. The maxWidth option does not seem to work; so set the CSS max-width property on the dialog widget instead.

In case you also want to constrain the maximum height, use the maxHeight option. It will correctly show a scrollbar when necessary.

$(function() {_x000D_
  var $dialog = $("#dialog");_x000D_
  $dialog.dialog({_x000D_
    autoOpen: false,_x000D_
    modal: true,_x000D_
    width: "auto"_x000D_
  });_x000D_
  /*_x000D_
   * max-width should be set on dialog widget because maxWidth option has known issues_x000D_
   * max-height should be set using maxHeight option_x000D_
   */_x000D_
  $dialog.dialog("widget").css("max-width", $(window).width() - 100);_x000D_
  $dialog.dialog("option", "maxHeight", $(window).height() - 100);_x000D_
  $(".test-link").on("click", function(e) {_x000D_
    e.preventDefault();_x000D_
    $dialog.html($(this.hash).html());_x000D_
    // if you change the content of dialog after it is created then reset the left_x000D_
    // coordinate otherwise content only grows up to the right edge of screen_x000D_
    $dialog.dialog("widget").css({ left: 0 });_x000D_
    $dialog.dialog("open");_x000D_
  });_x000D_
});
