As others have stated, you have to dereference the reference. The keys function requires that its argument starts with a %:

My preference:

foreach my $key (keys %{$ad_grp_ref}) {

According to Conway:

foreach my $key (keys %{ $ad_grp_ref }) {

Guess who you should listen to...

You might want to read through the Perl Reference Documentation.

If you find yourself doing a lot of stuff with references to hashes and hashes of lists and lists of hashes, you might want to start thinking about using Object Oriented Perl. There's a lot of nice little tutorials in the Perl documentation.

I think that it is better (for my expirience) to use: :first-of-type, :nth-of-type(), :last-of-type. It can be done whit a little changing of rules, but I was able to do much more than whit *-of-type, than *-child selectors.

Hm, looking at your first set of code, I think you have retrieved (maybe?) the hard drive model. The serial # comes from Win32_PhysicalMedia.

Get Hard Drive model

    ManagementObjectSearcher searcher = new
    ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");

   foreach(ManagementObject wmi_HD in searcher.Get())
   {
    HardDrive hd = new HardDrive();
    hd.Model = wmi_HD["Model"].ToString();
    hd.Type  = wmi_HD["InterfaceType"].ToString(); 
    hdCollection.Add(hd);
   }

Get the Serial Number

 searcher = new
    ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMedia");

   int i = 0;
   foreach(ManagementObject wmi_HD in searcher.Get())
   {
    // get the hard drive from collection
    // using index
    HardDrive hd = (HardDrive)hdCollection[i];

    // get the hardware serial no.
    if (wmi_HD["SerialNumber"] == null)
     hd.SerialNo = "None";
    else
     hd.SerialNo = wmi_HD["SerialNumber"].ToString();

    ++i;
   }

Hope this helps :)

Some points to note when working with foreach():

a) foreach works on the prospected copy of the original array. It means foreach() will have SHARED data storage until or unless a prospected copy is not created foreach Notes/User comments.

b) What triggers a prospected copy? A prospected copy is created based on the policy of copy-on-write, that is, whenever an array passed to foreach() is changed, a clone of the original array is created.

c) The original array and foreach() iterator will have DISTINCT SENTINEL VARIABLES, that is, one for the original array and other for foreach; see the test code below. SPL , Iterators, and Array Iterator.

Stack Overflow question How to make sure the value is reset in a 'foreach' loop in PHP? addresses the cases (3,4,5) of your question.

The following example shows that each() and reset() DOES NOT affect SENTINEL variables (for example, the current index variable) of the foreach() iterator.

$array = array(1, 2, 3, 4, 5);

list($key2, $val2) = each($array);
echo "each() Original (outside): $key2 => $val2<br/>";

foreach($array as $key => $val){
    echo "foreach: $key => $val<br/>";

    list($key2,$val2) = each($array);
    echo "each() Original(inside): $key2 => $val2<br/>";

    echo "--------Iteration--------<br/>";
    if ($key == 3){
        echo "Resetting original array pointer<br/>";
        reset($array);
    }
}

list($key2, $val2) = each($array);
echo "each() Original (outside): $key2 => $val2<br/>";

Output:

each() Original (outside): 0 => 1
foreach: 0 => 1
each() Original(inside): 1 => 2
--------Iteration--------
foreach: 1 => 2
each() Original(inside): 2 => 3
--------Iteration--------
foreach: 2 => 3
each() Original(inside): 3 => 4
--------Iteration--------
foreach: 3 => 4
each() Original(inside): 4 => 5
--------Iteration--------
Resetting original array pointer
foreach: 4 => 5
each() Original(inside): 0=>1
--------Iteration--------
each() Original (outside): 1 => 2

The class static variables can be declared in the header but must be defined in a .cpp file. This is because there can be only one instance of a static variable and the compiler can't decide in which generated object file to put it so you have to make the decision, instead.

To keep the definition of a static value with the declaration in C++11 a nested static structure can be used. In this case the static member is a structure and has to be defined in a .cpp file, but the values are in the header.

class A
{
private:
  static struct _Shapes {
     const std::string RECTANGLE {"rectangle"};
     const std::string CIRCLE {"circle"};
  } shape;
};

Instead of initializing individual members the whole static structure is initialized in .cpp:

A::_Shapes A::shape;

The values are accessed with

A::shape.RECTANGLE;

or -- since the members are private and are meant to be used only from A -- with

shape.RECTANGLE;

Note that this solution still suffers from the problem of the order of initialization of the static variables. When a static value is used to initialize another static variable, the first may not be initialized, yet.

// file.h
class File {
public:
  static struct _Extensions {
    const std::string h{ ".h" };
    const std::string hpp{ ".hpp" };
    const std::string c{ ".c" };
    const std::string cpp{ ".cpp" };
  } extension;
};

// file.cpp
File::_Extensions File::extension;

// module.cpp
static std::set<std::string> headers{ File::extension.h, File::extension.hpp };

In this case the static variable headers will contain either { "" } or { ".h", ".hpp" }, depending on the order of initialization created by the linker.

As mentioned by @abyss.7 you could also use constexpr if the value of the variable can be computed at compile time. But if you declare your strings with static constexpr const char* and your program uses std::string otherwise there will be an overhead because a new std::string object will be created every time you use such a constant:

class A {
public:
   static constexpr const char* STRING = "some value";
};
void foo(const std::string& bar);
int main() {
   foo(A::STRING); // a new std::string is constructed and destroyed.
}

From https://docs.gradle.org/current/userguide/dependency_management.html

If your goal is to have

str = "Hello\nWorld";

and output what it contains in string literal form, you can use JSON.stringify:

console.log(JSON.stringify(str)); // ""Hello\nWorld""

const str = "Hello\nWorld";_x000D_
const json = JSON.stringify(str);_x000D_
console.log(json); // ""Hello\nWorld""_x000D_
for (let i = 0; i < json.length; ++i) {_x000D_
    console.log(`${i}: ${json.charAt(i)}`);_x000D_
}

.as-console-wrapper {_x000D_
    max-height: 100% !important;_x000D_
}

console.log adds the outer quotes (at least in Chrome's implementation), but the content within them is a string literal (yes, that's somewhat confusing).

JSON.stringify takes what you give it (in this case, a string) and returns a string containing valid JSON for that value. So for the above, it returns an opening quote ("), the word Hello, a backslash (\), the letter n, the word World, and the closing quote ("). The linefeed in the string is escaped in the output as a \ and an n because that's how you encode a linefeed in JSON. Other escape sequences are similarly encoded.

Plain typo. hostspath vs hostpath ;)

@echo off 

set `hostspath`=%windir%\System32\drivers\etc\hosts 

echo 62.116.159.4 ns1.intranet.de >> `%hostspath%`   
echo 217.160.113.37 ns2.intranet.de >> `%hostpath%`  
echo 89.146.248.4 ns3.intranet.de >> `%hostpath%`   
echo 74.208.254.4 ns4.intranet.de >> `%hostpath%`   

exit 

In Bash if you export the variable within a subshell, using parentheses as shown, you avoid leaking the exported variables:

#!/bin/bash

TESTVARIABLE=hellohelloheloo
(
export TESTVARIABLE    
source ./test2.sh
)

The advantage here is that after you run the script from the command line, you won't see a $TESTVARIABLE leaked into your environment:

$ ./test.sh
hellohelloheloo
$ echo $TESTVARIABLE
                            #empty! no leak
$

Some time we need to set PATH variable for WINDOWS

%USERPROFILE%\AppData\Roaming\npm

Note: Do not forget to close the command prompt window and reopen it.

Yes, it's possible to use inline if-expressions:

{{ 'Update' if files else 'Continue' }}

One can directly store the returned output of a function in a file.

print(output statement, file=open("filename", "a"))

[Update: 2014-11-26] As Yar summarizes nicely below, before you do anything, make sure you know the URL of the submodule. If unknown, open .git/.gitmodules and examine the keysubmodule.<name>.url.

What worked for me was to remove the old submodule using git submodule deinit <submodule> followed by git rm <submodule-folder>. Then add the submodule again with the new folder name and commit. Checking git status before committing shows the old submodule renamed to the new name and .gitmodule modified.

$ git submodule deinit foo
$ git rm foo
$ git submodule add https://bar.com/foo.git new-foo
$ git status
renamed:    foo -> new-foo
modified:   .gitmodules
$ git commit -am "rename foo submodule to new-foo"

I think Apple are covering their backs a little here for a potentially kludgy piece of API.

  [self dismissViewControllerAnimated:NO completion:nil]

Is actually a bit of a fiddle. Although you can - legitimately - call this on the presented view controller, all it does is forward the message on to the presenting view controller. If you want to do anything over and above just dismissing the VC, you will need to know this, and you need to treat it much the same way as a delegate method - as that's pretty much what it is, a baked-in somewhat inflexible delegate method.

Perhaps they've come across loads of bad code by people not really understanding how this is put together, hence their caution.

But of course, if all you need to do is dismiss the thing, go ahead.

My own approach is a compromise, at least it reminds me what is going on:

  [[self presentingViewController] dismissViewControllerAnimated:NO completion:nil]

[Swift]

  self.presentingViewController?.dismiss(animated: false, completion:nil)

As many wrote earlier, SHOW FULL COLUMNS should be the preferred method to get column information. What's missing is a way to get charset after that without reaching metadata tables directly:

SHOW FULL COLUMNS FROM my_table WHERE Field = 'my_field'
SHOW COLLATION WHERE Collation = 'collation_you_got'

Just wanted to show you a way to save all your Bundle after onConfigurationChanged:

Create new Bundle just after your class:

public class MainActivity extends Activity {
    Bundle newBundy = new Bundle();

Next, after "protected void onCreate" add this:

@Override
public void onConfigurationChanged(Configuration newConfig) {
     super.onConfigurationChanged(newConfig);
     if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
            onSaveInstanceState(newBundy);
        } else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) {
            onSaveInstanceState(newBundy);
        }
}

@Override
public void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    outState.putBundle("newBundy", newBundy);
}

@Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
    super.onRestoreInstanceState(savedInstanceState);
    savedInstanceState.getBundle("newBundy");
}

If you add this all your crated classes into MainActivity will be saved.

But the best way is to add this in your AndroidManifest:

<activity name= ".MainActivity" android:configChanges="orientation|screenSize"/>

Another simple solution could be to use a structure or simple data class that contains the parameters as properties; that way you can have all the default values and behaviors set up ahead of time, passing the "parameter class" in as the single constructor parameter:

public class FooParams
{
    public int Size...
    protected myCustomStruct _ReasonForLife ...
}
public class Foo
{
    private FooParams _myParams;
    public Foo(FooParams myParams)
    {
          _myParams = myParams;
    }
}

This avoids the mess of multiple constructors (sometimes) and gives strong typing, default values, and other benefits not provided by a parameter array. It also makes it easy to carry forward since anything that inherits from Foo can still get to, or even add to, FooParams as needed. You still need to copy the constructor, but you always (most of the time) only (as a general rule) ever (at least, for now) need one constructor.

public class Bar : Foo
{
    public Bar(FooParams myParams) : base(myParams) {}
}

I really like the overloaded Initailize() and Class Factory Pattern approaches better, but sometimes you just need to have a smart constructor. Just a thought.

it sometimes occurs when we use a custom adapter in any activity of fragment . and we return null object i.e null view so the activity gets confused which view to load , so that is why this exception occurs

shows the position where to change the view

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

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

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

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

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

I have had the same problem, and here's how I solved it: I added the plugin "org.eclipse.core.runtime" in the "plugins" section on the "configuration" tab of the .product editor. I set it's start level to default and auto-start to true. I removed other plugins. My reasoning was this: Eclipse is complaining that the org.eclipse.core.runtime isn't started, so let's make sure that it does start, and that it's the only plugin that's starting.

My application ran fine after I did this. I then inspected the config.ini to see what changed, and saw that org.eclipse.core.runtime was now changed to org.eclipse.core.runtime@start. This is consistent with BalusC's suggestion, I just did it from the .product editor.

I just had this issue, it was because the IIS site was pointing at the wrong Application Pool.

Your server's response allows the request to include three specific non-simple headers:

Access-Control-Allow-Headers:origin, x-requested-with, content-type

but your request has a header not allowed by the server's response:

Access-Control-Request-Headers:access-control-allow-origin, content-type

All non-simple headers sent in a CORS request must be explicitly allowed by the Access-Control-Allow-Headers response header. The unnecessary Access-Control-Allow-Origin header sent in your request is not allowed by the server's CORS response. This is exactly what the "...not allowed by Access-Control-Allow-Headers" error message was trying to tell you.

There is no reason for the request to have this header: it does nothing, because Access-Control-Allow-Origin is a response header, not a request header.

Solution: Remove the setRequestHeader call that adds a Access-Control-Allow-Origin header to your request.

Believing this performance evaluation, the switch case is faster.

This is the conclusion:

The results show that the switch statement is faster to execute than the if-else-if ladder. This is due to the compiler's ability to optimise the switch statement. In the case of the if-else-if ladder, the code must process each if statement in the order determined by the programmer. However, because each case within a switch statement does not rely on earlier cases, the compiler is able to re-order the testing in such a way as to provide the fastest execution.

You need to rebuild your workspace using CTRL+B. I a problem where I'd be able to go to the function declarations but for some I wouldn't. After a rebuild, I could do all. I hope that helps.

The regex you're looking for is ^[A-Za-z.\s_-]+$

• ^ asserts that the regular expression must match at the beginning of the subject
• [] is a character class - any character that matches inside this expression is allowed
• A-Z allows a range of uppercase characters
• a-z allows a range of lowercase characters
• . matches a period rather than a range of characters
• \s matches whitespace (spaces and tabs)
• _ matches an underscore
• - matches a dash (hyphen); we have it as the last character in the character class so it doesn't get interpreted as being part of a character range. We could also escape it (\-) instead and put it anywhere in the character class, but that's less clear
• + asserts that the preceding expression (in our case, the character class) must match one or more times
• $ Finally, this asserts that we're now at the end of the subject

When you're testing regular expressions, you'll likely find a tool like regexpal helpful. This allows you to see your regular expression match (or fail to match) your sample data in real time as you write it.

Sometimes in situations like this I miss my youth, when Access was my poison of choice, and I could give each radio button in a group its own value.

My hack in C# is to use the tag to set the value, and when I make a selection from the group, I read the value of the tag of the selected radiobutton. In this example, directionGroup is the group in which I have four five radio buttons with "None" and "NE", "SE", "NW" and "SW" as the tags on the other four radiobuttons.

I proactively used a button to capture the value of the checked button, because because assigning one event handler to all of the buttons' CHeckCHanged event causes EACH button to fire, because changing one changes them all. So the value of sender is always the first RadioButton in the group. Instead, I use this method when I need to find out which one is selected, with the values I want to retrieve in the Tag property of each RadioButton.

  private void ShowSelectedRadioButton()
    {
        List<RadioButton> buttons = new List<RadioButton>();
        string selectedTag = "No selection";
        foreach (Control c in directionGroup.Controls)
        {
            if (c.GetType() == typeof(RadioButton))
            {
                buttons.Add((RadioButton)c);
            }
        }
        var selectedRb = (from rb in buttons where rb.Checked == true select rb).FirstOrDefault();
        if (selectedRb!=null)
        {
             selectedTag = selectedRb.Tag.ToString();
        }

        FormattableString result = $"Selected Radio button tag ={selectedTag}";
        MessageBox.Show(result.ToString());
    }

FYI, I have tested and used this in my work.

If you want to set date on page load then use this:

 $('#datetimepicker1').datetimepicker({
  minDate: new Date()
  });

This will set today's date as start date on page load itself and disable all the previous dates.
But if you want to set date on click of particular text-box instead of setting it on page load then use this: $('#datetimepicker1').datetimepicker(); $("#datetimepicker1").on("click", function (e) { $('#datetimepicker1').data("DateTimePicker").minDate(new Date()); });

In place of new Date(), we can use any string specifying Date in a format specified by us if we don't want to set current date as minimum date. e.g:

$('#datetimepicker1').data("DateTimePicker").minDate("10/15/2018");

You need to say the following (since you befriend a whole template instead of just a specialization of it, in which case you would just need to add a <> after the operator<<):

template<typename T>
friend std::ostream& operator<<(std::ostream& out, const MyClass<T>& classObj);

Actually, there is no need to declare it as a friend unless it accesses private or protected members. Since you just get a warning, it appears your declaration of friendship is not a good idea. If you just want to declare a single specialization of it as a friend, you can do that like shown below, with a forward declaration of the template before your class, so that operator<< is regognized as a template.

// before class definition ...
template <class T>
class MyClass;

// note that this "T" is unrelated to the T of MyClass !
template<typename T>
std::ostream& operator<<(std::ostream& out, const MyClass<T>& classObj);

// in class definition ...
friend std::ostream& operator<< <>(std::ostream& out, const MyClass<T>& classObj);

Both the above and this way declare specializations of it as friends, but the first declares all specializations as friends, while the second only declares the specialization of operator<< as a friend whose T is equal to the T of the class granting friendship.

And in the other case, your declaration looks OK, but note that you cannot += a MyClass<T> to a MyClass<U> when T and U are different type with that declaration (unless you have an implicit conversion between those types). You can make your += a member template

// In MyClass.h
template<typename U>
MyClass<T>& operator+=(const MyClass<U>& classObj);


// In MyClass.cpp
template <class T> template<typename U>
MyClass<T>& MyClass<T>::operator+=(const MyClass<U>& classObj) {
  // ...
  return *this;
}

The code is written quickly and did not refactored, raise the rating of my answer if you want me to improve the code and give ES2015 version (classes).

If your problem is only with function overloading (you need to check if 'parameters' parameter is 'parameters' and not 'callback'), i would recommend you don't bother about argument type and
use this approach. The idea is simple - use literal objects to combine your parameters:

function getData(id, opt){
    var data = voodooMagic(id, opt.parameters);
    if (opt.callback!=undefined)
      opt.callback.call(data);
    return data;         
}

getData(5, {parameters: "1,2,3", callback: 
    function(){for (i=0;i<=1;i--)alert("FAIL!");}
});

just use simple css

.big-checkbox {width: 1.5rem; height: 1.5rem;top:0.5rem}

This should also work (even in SQL-Server 2005):

SELECT *
FROM dbo.MyTable
WHERE Created >= DATEADD(hh,23,DATEADD(day, DATEDIFF(day, 0, Created - 1), 0))
  AND Created <  DATEADD(hh,7,DATEADD(day, DATEDIFF(day, 0, Created), 0))

     this.run=function(){
          if(!document || !document.body || !window[objId]){

The answer is yes, if you write return statement the controls goes back to to the caller method immediately. With an exception of finally block, which gets executed after the return statement.

and finally can also override the value you have returned, if you return inside of finally block. LINK: Try-catch-finally-return clarification

Return Statement definition as per:

Java Docs:

a return statement can be used to branch out of a control flow block and exit the method

MSDN Documentation:

The return statement terminates the execution of a function and returns control to the calling function. Execution resumes in the calling function at the point immediately following the call.

Wikipedia:

A return statement causes execution to leave the current subroutine and resume at the point in the code immediately after where the subroutine was called, known as its return address. The return address is saved, usually on the process's call stack, as part of the operation of making the subroutine call. Return statements in many languages allow a function to specify a return value to be passed back to the code that called the function.

You should have to use DateTime.TryParseExact.

var newDate = DateTime.ParseExact("20111120", 
                                  "yyyyMMdd", 
                                   CultureInfo.InvariantCulture);

OR

string str = "20111021";
string[] format = {"yyyyMMdd"};
DateTime date;

if (DateTime.TryParseExact(str, 
                           format, 
                           System.Globalization.CultureInfo.InvariantCulture,
                           System.Globalization.DateTimeStyles.None, 
                           out date))
{
     //valid
}

I wrote my thoughts of static classes in an earlier Stack Overflow answer: Class with single method -- best approach?

I used to love utility classes filled up with static methods. They made a great consolidation of helper methods that would otherwise lie around causing redundancy and maintenance hell. They're very easy to use, no instantiation, no disposal, just fire'n'forget. I guess this was my first unwitting attempt at creating a service-oriented architecture - lots of stateless services that just did their job and nothing else. As a system grows however, dragons be coming.

Polymorphism

Say we have the method UtilityClass.SomeMethod that happily buzzes along. Suddenly we need to change the functionality slightly. Most of the functionality is the same, but we have to change a couple of parts nonetheless. Had it not been a static method, we could make a derivate class and change the method contents as needed. As it's a static method, we can't. Sure, if we just need to add functionality either before or after the old method, we can create a new class and call the old one inside of it - but that's just gross.

Interface woes

Static methods cannot be defined through interfaces for logic reasons. And since we can't override static methods, static classes are useless when we need to pass them around by their interface. This renders us unable to use static classes as part of a strategy pattern. We might patch some issues up by passing delegates instead of interfaces.

Testing

This basically goes hand in hand with the interface woes mentioned above. As our ability of interchanging implementations is very limited, we'll also have trouble replacing production code with test code. Again, we can wrap them up, but it'll require us to change large parts of our code just to be able to accept wrappers instead of the actual objects.

Fosters blobs

As static methods are usually used as utility methods and utility methods usually will have different purposes, we'll quickly end up with a large class filled up with non-coherent functionality - ideally, each class should have a single purpose within the system. I'd much rather have a five times the classes as long as their purposes are well defined.

Parameter creep

To begin with, that little cute and innocent static method might take a single parameter. As functionality grows, a couple of new parameters are added. Soon further parameters are added that are optional, so we create overloads of the method (or just add default values, in languages that support them). Before long, we have a method that takes 10 parameters. Only the first three are really required, parameters 4-7 are optional. But if parameter 6 is specified, 7-9 are required to be filled in as well... Had we created a class with the single purpose of doing what this static method did, we could solve this by taking in the required parameters in the constructor, and allowing the user to set optional values through properties, or methods to set multiple interdependent values at the same time. Also, if a method has grown to this amount of complexity, it most likely needs to be in its own class anyway.

Demanding consumers to create an instance of classes for no reason

One of the most common arguments is: Why demand that consumers of our class create an instance for invoking this single method, while having no use for the instance afterwards? Creating an instance of a class is a very very cheap operation in most languages, so speed is not an issue. Adding an extra line of code to the consumer is a low cost for laying the foundation of a much more maintainable solution in the future. And finally, if you want to avoid creating instances, simply create a singleton wrapper of your class that allows for easy reuse - although this does make the requirement that your class is stateless. If it's not stateless, you can still create static wrapper methods that handle everything, while still giving you all the benefits in the long run. Finally, you could also make a class that hides the instantiation as if it was a singleton: MyWrapper.Instance is a property that just returns new MyClass();

Only a Sith deals in absolutes

Of course, there are exceptions to my dislike of static methods. True utility classes that do not pose any risk to bloat are excellent cases for static methods - System.Convert as an example. If your project is a one-off with no requirements for future maintenance, the overall architecture really isn't very important - static or non static, doesn't really matter - development speed does, however.

Standards, standards, standards!

Using instance methods does not inhibit you from also using static methods, and vice versa. As long as there's reasoning behind the differentiation and it's standardised. There's nothing worse than looking over a business layer sprawling with different implementation methods.

Two ways to achieve it.

1) Need to start the dialer via code, without user interaction.

You need Action_Dial,

use below code it will open Dialer with number specified

Intent intent = new Intent(Intent.ACTION_DIAL);
intent.setData(Uri.parse("tel:0123456789"));
startActivity(intent); 

The 'tel:' prefix is required, otherwhise the following exception will be thrown: java.lang.IllegalStateException: Could not execute method of the activity.

Action_Dial doesn't require any permission.

If you want to initiate the call directly without user's interaction , You can use action Intent.ACTION_CALL. In this case, you must add the following permission in your AndroidManifest.xml:

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

2) Need user to click on Phone_Number string and start the call.

android:autoLink="phone" 

You need to use TextView with below property.

android:autoLink="phone" android:linksClickable="true" a textView property

You don't need to use intent or to get permission via this way.

Starting with Chrome 38 you can do this without any plugins. Just click inspect element (or F12 hotkey), then click on toggle device mod (the phone button)

and you will see something like this:

Among many other features it allows you to simulate specific internet connection (3G, GPRS)

Using git merge --squash <feature branch> as the accepted answer suggests does the trick but it will not show the merged branch as actually merged.

Therefore an even better solution is to:

• Create a new branch from the latest master, commit in the master branch where the feature branch initiated.
• Merge <feature branch> into the above using git merge --squash
• Merge the newly created branch into master. This way, the feature branch will contain only one commit and the merge will be represented in a short and tidy illustration.

This wiki explains the procedure in detail.

In the following example, the left hand screenshot is the result of qgit and the right hand screenshot is the result of:

git log --graph --decorate --pretty=oneline --abbrev-commit

Both screenshots show the same range of commits in the same repository. Nonetheless, the right one is more compact thanks to --squash.

• Over time, the master branch deviated from db.
• When the db feature was ready, a new branch called tag was created in the same commit of master that db has its root.
• From tag a git merge --squash db was performed and then all changes were staged and committed in a single commit.
• From master, tag got merged: git merge tag.
• The branch search is irrelevant and not merged in any way.

You must to download MySQLConnection NET from here.

Then you need add MySql.Data.DLL to MSVisualStudio like this:

1. Open menu project
2. Add
3. Reference
4. Browse to C:\Program Files (x86)\MySQL\MySQL Connector Net 8.0.12\Assemblies\v4.5.2
5. Add MySql.Data.dll

If you want to know more visit: enter link description here

To use in the code you must import the library:

using MySql.Data.MySqlClient;

An example with connectio to Mysql database (NO SSL MODE) by means of Click event:

using System;
using System.Windows;
using MySql.Data.MySqlClient;


namespace Deportes_WPF
{

public partial class Login : Window
{
    private MySqlConnection connection;
    private string server;
    private string database;
    private string user;
    private string password;
    private string port;
    private string connectionString;
    private string sslM;

    public Login()
    {
        InitializeComponent();

        server = "server_name";
        database = "database_name";
        user = "user_id";
        password = "password";
        port = "3306";
        sslM = "none";

        connectionString = String.Format("server={0};port={1};user id={2}; password={3}; database={4}; SslMode={5}", server, port, user, password, database, sslM);

        connection = new MySqlConnection(connectionString);
    }

    private void conexion()
    {
        try
        {
            connection.Open();

            MessageBox.Show("successful connection");

            connection.Close();
        }
        catch (MySqlException ex)
        {
            MessageBox.Show(ex.Message + connectionString);
        }
    }

    private void btn1_Click(object sender, RoutedEventArgs e)
    {
        conexion();
    }
  }

}

I eventually figured out an easy way to do it:

1. On your Twitter feed, click the date/time of the tweet containing the video. That will open the single tweet view
2. Look for the down-pointing arrow at the top-right corner of the tweet, click it to open drop-down menue
3. Select the "Embed Video" option and copy the HTML embed code and Paste it to Notepad
4. Find the last "t.co" shortened URL inside the HTML code (should be something like this: https://``t.co/tQM43ftXyM). Copy this URL and paste it in a new browser tab.
5. The browser will expand the shortened URL to something which looks like this: https://twitter.com/UserName/status/828267001496784896/video/1

This is the link to the Twitter Card containing the native video. Pasting this link in a new tweet or DM will include the native video in it!

in case someone got stuck with this and none of the answers above worked, below is what worked for me. Hope it helps.

var oldString = "\\r|\\n";

// None of these worked for me
// var newString = oldString(@"\\", @"\");
// var newString = oldString.Replace("\\\\", "\\");
// var newString = oldString.Replace("\\u5b89", "\u5b89");
// var newString = Regex.Replace(oldString , @"\\", @"\");

// This is what worked
var newString = Regex.Unescape(oldString);
// newString is now "\r|\n"

The problem I run into is I have an existing IIS machine. I then deploy a static React app to it. When you use router, the URL that displays is actually virtual, not real. If you hit F5 it goes to IIS, not index.js, and your return will be 404 file not found. How I resolved it was simple. I have a public folder in my react app. In that public folder I created the same folder name as the virtual routing. In this folder, I have an index.html with the following code:

<script>
  {
    localStorage.setItem("redirect", "/ansible/");
    location.href = "/";
  }
</script>

Now what this does is for this session, I'm adding the "routing" path I want it to go. Then inside my App.js I do this (Note ... is other code but too much to put here for a demo):

import React, { Component } from "react";
import { Route, Link } from "react-router-dom";
import { BrowserRouter as Router } from "react-router-dom";
import { Redirect } from 'react-router';
import Ansible from "./Development/Ansible";
import Code from "./Development/Code";
import Wood from "./WoodWorking";
import "./App.css";

class App extends Component {
  render() {
    const redirect = localStorage.getItem("redirect");

    if(redirect) {
      localStorage.removeItem("redirect");
    }

    return (
      <Router>
        {redirect ?<Redirect to={redirect}/> : ""}
        <div className="App">
        ...
          <Link to="/">
            <li>Home</li>
          </Link>
          <Link to="/dev">
            <li>Development</li>
          </Link>
          <Link to="/wood">
            <li>Wood Working</li>
          </Link>
        ...
          <Route
            path="/"
            exact
            render={(props) => (
              <Home {...props} />
            )}
          />
          <Route
            path="/dev"
            render={(props) => (
              <Code {...props} />
            )}
          />
          <Route
            path="/wood"
            render={(props) => (
              <Wood {...props} />
            )}
          />
          <Route
            path="/ansible/"
            exact
            render={(props) => (
              <Ansible {...props} checked={this.state.checked} />
            )}
          />
          ...
      </Router>
    );
  }
}

export default App;

Actual usage: chizl.com

I just needed a simple testing button for react.js. Here is what I did and it worked.

function Testing(){
 var f=function testing(){
         console.log("Testing Mode activated");
         UserData.authenticated=true;
         UserData.userId='123';
       };
 console.log("Testing Mode");

 return (<div><button onClick={f}>testing</button></div>);
}

I really like cottsaks solution and think its very clearly explained. my only addition was to alter step 2 as follows

public abstract class MyController : Controller
{

    #region Http404 handling

    protected override void HandleUnknownAction(string actionName)
    {
        //if controller is ErrorController dont 'nest' exceptions
        if(this.GetType() != typeof(ErrorController))
        this.InvokeHttp404(HttpContext);
    }

    public ActionResult InvokeHttp404(HttpContextBase httpContext)
    {
        IController errorController = ObjectFactory.GetInstance<ErrorController>();
        var errorRoute = new RouteData();
        errorRoute.Values.Add("controller", "Error");
        errorRoute.Values.Add("action", "Http404");
        errorRoute.Values.Add("url", httpContext.Request.Url.OriginalString);
        errorController.Execute(new RequestContext(
             httpContext, errorRoute));

        return new EmptyResult();
    }

    #endregion
}

Basically this stops urls containing invalid actions AND controllers from triggering the exception routine twice. eg for urls such as asdfsdf/dfgdfgd

Three things to note:

1)Working Directory ----- folder where our codes file are present

2)Local Repository ------ This is inside our system. When we first time make COMMIT command then this Local Repository is created. in the same place where is our Working directory ,
Checkit ( .git ) file get created.
After that when ever we do commit , this will store the changes we make in the file of Working Directory to local Repository (.git)

3)Remote Repository ----- This is situated outside our system like on servers located any where in the world . like github. When we make PUSH command then codes from our local repository get stored to this Remote Repository

partition() may be better then split() for this purpose as it has the better predicable results for situations you have no delimiter or more delimiters.

I believe the problem with "go to" packages is that they would work diferently for each language.

If you use Javascript js-hyperclick and hyperclick (since code-links is deprecated) may do what you need.

Use symbols-view package which let your search and jump to functions declaration but just of current opened file. Unfortunately, I don't know of any other language's equivalent.

There is also another package which could be useful for go-to in Python: python-tools

As of May 2016, recent version of Atom now support "Go-To" natively. At the GitHub repo for this module you get a list of the following keys:

• symbols-view:toggle-file-symbols to Show all symbols in current file
• symbols-view:toggle-project-symbols to Show all symbols in the project
• symbols-view:go-to-declaration to Jump to the symbol under the cursor
• symbols-view:return-from-declaration to Return from the jump

I now only have one thing missing with Atom for this: mouse click bindings. There's an open issue on Github if anyone want to follow that feature.

Following Christian Graus' advice in his "Things I Hate about Microsoft" blog titled "Path.Combine is essentially useless.", here is my solution:

public static class Pathy
{
    public static string Combine(string path1, string path2)
    {
        if (path1 == null) return path2
        else if (path2 == null) return path1
        else return path1.Trim().TrimEnd(System.IO.Path.DirectorySeparatorChar)
           + System.IO.Path.DirectorySeparatorChar
           + path2.Trim().TrimStart(System.IO.Path.DirectorySeparatorChar);
    }

    public static string Combine(string path1, string path2, string path3)
    {
        return Combine(Combine(path1, path2), path3);
    }
}

Some advise that the namespaces should collide, ... I went with Pathy, as a slight, and to avoid namespace collision with System.IO.Path.

Edit: Added null parameter checks

Separate your rules with a semi colon in a single declaration:

<span style="color:blue;font-style:italic">Test</span>

I spent most of last week at a university library studying debugging of concurrent code. The central problem is concurrent code is non-deterministic. Typically, academic debugging has fallen into one of three camps here:

1. Event-trace/replay. This requires an event monitor and then reviewing the events that were sent. In a UT framework, this would involve manually sending the events as part of a test, and then doing post-mortem reviews.
2. Scriptable. This is where you interact with the running code with a set of triggers. "On x > foo, baz()". This could be interpreted into a UT framework where you have a run-time system triggering a given test on a certain condition.
3. Interactive. This obviously won't work in an automatic testing situation. ;)

Now, as above commentators have noticed, you can design your concurrent system into a more deterministic state. However, if you don't do that properly, you're just back to designing a sequential system again.

My suggestion would be to focus on having a very strict design protocol about what gets threaded and what doesn't get threaded. If you constrain your interface so that there is minimal dependancies between elements, it is much easier.

Good luck, and keep working on the problem.

You may use the class java.util.Random with method

char c = (char)(rnd.nextInt(128-32))+32 

20x to get Bytes, which you interpret as ASCII. If you're fine with ASCII.

32 is the offset, from where the characters are printable in general.

Edit: I noticed that some people are cutting and pasting the invocation here. The answer I originally gave was relevant for the OP only. Here's a more modern invocation style (including using the more conventional port of 8000):

java -agentlib:jdwp=transport=dt_socket,server=y,address=8000,suspend=n <other arguments>

Original answer follows.

Try this:

java -Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=4000,suspend=n myapp

Two points here:

1. No spaces in the runjdwp option.
2. Options come before the class name. Any arguments you have after the class name are arguments to your program!

Expanding on mVck's answer above, the following logic determines whether "Never ask again" has been checked for a given Permission Request:

bool bStorage = grantResults[0] == Permission.Granted;

        _bStorageRationaleBefore == false && _bStorageRationaleAfter == false

                RequestPermissions(requiredPermissions.ToArray(), requestCode);
                return;
            }
        }
    }            

    OnCreate2(savedInstanceState);
}

The Google Guava library has min and max methods in its Chars, Ints, Longs, etc. classes.

So you can simply use:

Chars.min(myarray)

No conversions are required and presumably it's efficiently implemented.

If you want an ANSI SQL-92 version:

select view_definition from information_schema.views where table_name = 'view_name';

if ( condition ) {
    return;
}

The return exits the function returning undefined.

The exit statement doesn't exist in javascript.

The break statement allows you to exit a loop, not a function. For example:

var i = 0;
while ( i < 10 ) {
    i++;
    if ( i === 5 ) {
        break;
    }
}

This also works with the for and the switch loops.

As previously stated, it's not directly possible, but you can set up Apache or nginx + SSL on a EC2 instance, CNAME your desired domain to that, and reverse-proxy to the (non-custom domain) S3 URLs.

Even though CMD is written down in the Dockerfile, it really is runtime information. Just like EXPOSE, but contrary to e.g. RUN and ADD. By this, I mean that you can override it later, in an extending Dockerfile, or simple in your run command, which is what you are experiencing. At all times, there can be only one CMD.

If you want to run multiple services, I indeed would use supervisor. You can make a supervisor configuration file for each service, ADD these in a directory, and run the supervisor with supervisord -c /etc/supervisor to point to a supervisor configuration file which loads all your services and looks like

[supervisord]
nodaemon=true

[include]
files = /etc/supervisor/conf.d/*.conf

If you would like more details, I wrote a blog on this subject here: http://blog.trifork.com/2014/03/11/using-supervisor-with-docker-to-manage-processes-supporting-image-inheritance/

Today, I would recommend using Task.CompletedTask to accomplish this.

Pre .net 4.6:

Using Task.FromResult(0) or Task.FromResult<object>(null) will incur less overhead than creating a Task with a no-op expression. When creating a Task with a result pre-determined, there is no scheduling overhead involved.

To deal with situations where there are a possibility of multiple values (v in your example), I use PIVOT and LISTAGG:

SELECT * FROM
(
  SELECT id, k, v
  FROM _kv 
)
PIVOT 
(
  LISTAGG(v ,',') 
  WITHIN GROUP (ORDER BY k) 
  FOR k IN ('name', 'age','gender','status')
)
ORDER BY id;

Since you want dynamic values, use dynamic SQL and pass in the values determined by running a select on the table data before calling the pivot statement.

You can try this as well:

from time import perf_counter

t0 = perf_counter()

...

t1 = perf_counter()
time_taken = t1 - t0

If you're going to compile a 64bit version(x86_64) of php use: /usr/lib64/

For architectures (i386 ... i686) use /usr/lib/

I recommend compiling php to the same architecture as apache. As you're using a 64bit linux i asume your apache is also compiled for x86_64.

You can use

<mat-checkbox [attr.checked] = "myCondition ? 'checked' : null">

if the checked attribute is set to null, it gets removed from the html tag

or you can use Vega's anwser which should work too (mine is a completion that can be usefull if you don't want to link it with ngModel)

try the following command to get the root access

$ sudo -i 

It's completely up to you. You can either put them in the header or not, as long as the elements within them are internal navigation elements only (i.e. don't link to external sites such as a twitter or facebook account) then it's fine.

They tend to get placed in a header simply because that's where navigation often goes, but it's not set in stone.

You can read more about it at HTML5 Doctor.

O(n) is big O notation used for writing time complexity of an algorithm. When you add up the number of executions in an algoritm you'll get an expression in result like 2N+2, in this expression N is the dominating term(the term having largest effect on expression if its value increases or decreases). Now O(N) is the time comlexity while N is dominating term. Example

For i= 1 to n;
  j= 0;
while(j<=n);
  j=j+1;

here total number of executions for inner loop are n+1 and total number of executions for outer loop are n(n+1)/2, so total number of executions for whole algorithm are n+1+n(n+1/2) = (n^2+3n)/2. here n^2 is the dominating term so the time complexity for this algorithm is O(n^2)

Update 2019

Remember that whatever CSS overrides you define must be the same CSS specificity or greater in order to properly override Bootstrap's CSS.

Bootstrap 4.1+

The Navbar is transparent by default. If you only want to change the background color, it can be done simply by applying the color to the <navbar class="bg-custom">, but remember that won't change the other colors such as the links, hover and dropdown menu colors.

Here's CSS that will change any relevant Navbar colors in Bootstrap 4...

/* change the background color */
.navbar-custom {
    background-color: #ff5500;
}
/* change the brand and text color */
.navbar-custom .navbar-brand,
.navbar-custom .navbar-text {
    color: rgba(255,255,255,.8);
}
/* change the link color */
.navbar-custom .navbar-nav .nav-link {
    color: rgba(255,255,255,.5);
}
/* change the color of active or hovered links */
.navbar-custom .nav-item.active .nav-link,
.navbar-custom .nav-item:focus .nav-link,
.navbar-custom .nav-item:hover .nav-link {
    color: #ffffff;
}

Demo: http://www.codeply.com/go/U9I2byZ3tS

Override Navbar Light or Dark

If you're using the Bootstrap 4 Navbar navbar-light or navbar-dark classes, then use this in the overrides. For example, changing the Navbar link colors...

.navbar-light .nav-item.active .nav-link,
.navbar-light .nav-item:focus .nav-link,
.navbar-light .nav-item:hover .nav-link {
        color: #ffffff;
}

When making any Bootstrap customizations, you need to understand CSS Specificity. Overrides in your custom CSS need to use selectors that are as specific as the bootstrap.css. Read more

Transparent Navbar

Notice that the Bootstrap 4 Navbar is transparent by default. Use navbar-dark for dark/bold background colors, and use navbar-light if the navbar is a lighter color. This will effect the color of the text and color of the toggler icon as explained here.

Write editTextBackground.xml in drawable folder in resources

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <stroke
        android:width="1dp"
        android:color="@color/borderColor" />
</shape>

don't forget to declare color in resources named borderColor.

and assign this background to the EditText in xml background attribute

<EditText
    android:id="@+id/text"
    android:background="@drawable/editTextBackground"
    />

and it'll set border to EditText.

UPDATE

You can change border of edit text without drawable by using style attribute

style="@style/Widget.AppCompat.EditText"

Method overloading deals with the notion of having two or more methods in the same class with the same name but different arguments.

void foo(int a)
void foo(int a, float b)

Method overriding means having two methods with the same arguments, but different implementations. One of them would exist in the parent class, while another will be in the derived, or child class. The @Override annotation, while not required, can be helpful to enforce proper overriding of a method at compile time.

class Parent {
    void foo(double d) {
        // do something
    }
}

class Child extends Parent {

    @Override
    void foo(double d){
        // this method is overridden.  
    }
}

I couldn't delete the system image (idk why), so I took the approach of deleting all occurrences of g:skin in any xml file since eclipse don't know what that is:

$ find . -type f -name "*.xml" -print0 | xargs -0 sed -i /d:skin/d

On windows you might want to run it within Cygwin or cmder

maybe

var re = /^https?:\/\/[^/]+/i;
window.location.href = re.exec(window.location.href)[0];

is what you're looking for?

Note that the answer from @unutbu will be correct until you want to set the value to something new, then it will not work if your dataframe is a view.

In [4]: df = pd.DataFrame({'foo':list('ABC')}, index=[0,2,1])
In [5]: df['bar'] = 100
In [6]: df['bar'].iloc[0] = 99
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pandas-0.16.0_19_g8d2818e-py2.7-macosx-10.9-x86_64.egg/pandas/core/indexing.py:118: SettingWithCopyWarning:
A value is trying to be set on a copy of a slice from a DataFrame

See the the caveats in the documentation: http://pandas.pydata.org/pandas-docs/stable/indexing.html#indexing-view-versus-copy
  self._setitem_with_indexer(indexer, value)

Another approach that will consistently work with both setting and getting is:

In [7]: df.loc[df.index[0], 'foo']
Out[7]: 'A'
In [8]: df.loc[df.index[0], 'bar'] = 99
In [9]: df
Out[9]:
  foo  bar
0   A   99
2   B  100
1   C  100

It is worth noting that the accepted answer will round small floats down to zero.

>>> import numpy as np 
>>> arr = np.asarray([2.92290007e+00, -1.57376965e-03, 4.82011728e-08, 1.92896977e-12])
>>> print(arr)
[ 2.92290007e+00 -1.57376965e-03  4.82011728e-08  1.92896977e-12]
>>> np.round(arr, 2)
array([ 2.92, -0.  ,  0.  ,  0.  ]) 

You can use set_printoptions and a custom formatter to fix this and get a more numpy-esque printout with fewer decimal places:

>>> np.set_printoptions(formatter={'float': "{0:0.2e}".format})
>>> print(arr)
[2.92e+00 -1.57e-03 4.82e-08 1.93e-12]  

This way, you get the full versatility of format and maintain the full precision of numpy's datatypes.

Also note that this only affects printing, not the actual precision of the stored values used for computation.

The total of 7 numbers in an array can be created as:

import java.util.*;
class Sum
{
   public static void main(String arg[])
   {
     int a[]=new int[7];
     int total=0;
     Scanner n=new Scanner(System.in);
     System.out.println("Enter the no. for total");

     for(int i=0;i<=6;i++) 
     {
       a[i]=n.nextInt();
       total=total+a[i];
      }
       System.out.println("The total is :"+total);
    }
}

Most of my needs were satisfied by this answer https://stackoverflow.com/a/2989277/3001007 by krzysztof. But one issue with that code (i faced was), the binding won't work with multiple controls. So I changed _recursionProtection with a Guid based implementation. So it's working for Multiple controls in same window as well.

 public class RichTextBoxHelper : DependencyObject
    {
        private static List<Guid> _recursionProtection = new List<Guid>();

        public static string GetDocumentXaml(DependencyObject obj)
        {
            return (string)obj.GetValue(DocumentXamlProperty);
        }

        public static void SetDocumentXaml(DependencyObject obj, string value)
        {
            var fw1 = (FrameworkElement)obj;
            if (fw1.Tag == null || (Guid)fw1.Tag == Guid.Empty)
                fw1.Tag = Guid.NewGuid();
            _recursionProtection.Add((Guid)fw1.Tag);
            obj.SetValue(DocumentXamlProperty, value);
            _recursionProtection.Remove((Guid)fw1.Tag);
        }

        public static readonly DependencyProperty DocumentXamlProperty = DependencyProperty.RegisterAttached(
            "DocumentXaml",
            typeof(string),
            typeof(RichTextBoxHelper),
            new FrameworkPropertyMetadata(
                "",
                FrameworkPropertyMetadataOptions.AffectsRender | FrameworkPropertyMetadataOptions.BindsTwoWayByDefault,
                (obj, e) =>
                {
                    var richTextBox = (RichTextBox)obj;
                    if (richTextBox.Tag != null && _recursionProtection.Contains((Guid)richTextBox.Tag))
                        return;


                    // Parse the XAML to a document (or use XamlReader.Parse())

                    try
                    {
                        string docXaml = GetDocumentXaml(richTextBox);
                        var stream = new MemoryStream(Encoding.UTF8.GetBytes(docXaml));
                        FlowDocument doc;
                        if (!string.IsNullOrEmpty(docXaml))
                        {
                            doc = (FlowDocument)XamlReader.Load(stream);
                        }
                        else
                        {
                            doc = new FlowDocument();
                        }

                        // Set the document
                        richTextBox.Document = doc;
                    }
                    catch (Exception)
                    {
                        richTextBox.Document = new FlowDocument();
                    }

                    // When the document changes update the source
                    richTextBox.TextChanged += (obj2, e2) =>
                        {
                            RichTextBox richTextBox2 = obj2 as RichTextBox;
                            if (richTextBox2 != null)
                            {
                                SetDocumentXaml(richTextBox, XamlWriter.Save(richTextBox2.Document));
                            }
                        };
                }
            )
        );
    }

Dictionary keys should be unique !

In my case, I was using a Dictionary, and I found two items in it have accidentally the same key.

Dictionary<string, string> myDictionary = new Dictionary<string, string>() {
            {"KEY1", "V1"},
            {"KEY1", "V2" },
            {"KEY3", "V3"},
        };

Sorting by C and D needs to be put into number form for the corresponding column, ie 3 and 4, respectively. Eg Order By 2 asc")

Based on the error:

Required String parameter 'action' is not present

There needs to be a request parameter named action present in the request for Spring to map the request to your handler handleSave.

The HTML that you pasted shows no such parameter.

Just as a note you can also use this for iPads:

activityViewController.popoverPresentationController?.sourceView = sender

So the popover pops from the sender (the button in that case).

Let me try to answer in few words.

Hadoop is an eco-system which comprises of all other tools. So, you can't compare Hadoop but you can compare MapReduce.

Here are my few cents:

1. Hive: If your need is very SQLish meaning your problem statement can be catered by SQL, then the easiest thing to do would be to use Hive. The other case, when you would use hive is when you want a server to have certain structure of data.
2. Pig: If you are comfortable with Pig Latin and you need is more of the data pipelines. Also, your data lacks structure. In those cases, you could use Pig. Honestly there is not much difference between Hive & Pig with respect to the use cases.
3. MapReduce: If your problem can not be solved by using SQL straight, you first should try to create UDF for Hive & Pig and then if the UDF is not solving the problem then getting it done via MapReduce makes sense.

In ASP.NET, when should I use Session.Clear() rather than Session.Abandon()?

Session.Abandon() destroys the session and the Session_OnEnd event is triggered.

Session.Clear() just removes all values (content) from the Object. The session with the same key is still alive.

So, if you use Session.Abandon(), you lose that specific session and the user will get a new session key. You could use it for example when the user logs out.

Use Session.Clear(), if you want that the user remaining in the same session (if you don't want him to relogin for example) and reset all his session specific data.

What is the difference between Session.Abandon() and Session.Clear()

Clear - Removes all keys and values from the session-state collection.

Abandon - removes all the objects stored in a Session. If you do not call the Abandon method explicitly, the server removes these objects and destroys the session when the session times out. It also raises events like Session_End.

Session.Clear can be compared to removing all books from the shelf, while Session.Abandon is more like throwing away the whole shelf.

...

Generally, in most cases you need to use Session.Clear. You can use Session.Abandon if you are sure the user is going to leave your site.

So back to the differences:

• Abandon raises Session_End request.
• Clear removes items immediately, Abandon does not.
• Abandon releases the SessionState object and its items so it can garbage collected.
• Clear keeps SessionState and resources associated with it.

Session.Clear() or Session.Abandon() ?

You use Session.Clear() when you don't want to end the session but rather just clear all the keys in the session and reinitialize the session.

Session.Clear() will not cause the Session_End eventhandler in your Global.asax file to execute.

But on the other hand Session.Abandon() will remove the session altogether and will execute Session_End eventhandler.

Session.Clear() is like removing books from the bookshelf

Session.Abandon() is like throwing the bookshelf itself.

Question

I check on some sessions if not equal null in the page load. if one of them equal null i wanna to clear all the sessions and redirect to the login page?

Answer

If you want the user to login again, use Session.Abandon.

Try the below JS

$(function() {
    $('#type').change(function(){
        $('#row_dim').hide(); 
        if ($(this).val() == 'parcel')
        {
             $('#row_dim').show();
        }
    });
});

One could argue that the reasoning behind Null Object Pattern is similar to one in favour of returning the empty collection.

Syntax for establishing a raw network connection using telnet is this:

telnet {domain_name} {port_number}

So telnet to your smtp server like

telnet smtp.mydomain.com 25

And copy and paste the below

helo client.mydomain.com
mail from:<[email protected]>
rcpt to:<[email protected]>
data
From: [email protected]
Subject: test mail from command line

this is test number 1
sent from linux box
.
quit

Note : Do not forgot the "." at the end which represents the end of the message. The "quit" line exits ends the session.

A simple possible syntax will be:

<div className={`wrapper searchDiv ${this.state.something}`}>

I tried what Samuel Slade has suggested. Didn't work for me. The PropertyInfo list was coming as empty. So, I tried the following and it worked for me.

    Type type = typeof(Record);
    FieldInfo[] properties = type.GetFields();
    foreach (FieldInfo property in properties) {
       Debug.LogError(property.Name);
    }

I had a case where I was entering text into a field after which the text would be removed automatically. Turned out it was due to some site functionality where you had to press the enter key after entering the text into the field. So, after sending your barcode text with sendKeys method, send 'enter' directly after it. Note that you will have to import the selenium Keys class. See my code below.

import org.openqa.selenium.Keys;

String barcode="0000000047166";
WebElement element_enter = driver.findElement(By.xpath("//*[@id='div-barcode']"));
element_enter.findElement(By.xpath("your xpath")).sendKeys(barcode);

element_enter.sendKeys(Keys.RETURN); // this will result in the return key being pressed upon the text field

I hope it helps..

I wanted something a bit slimmer for RSpec/Ruby so that the custom code only had to live in one place. Here's my solution:

/spec/support/selenium.rb
...
RSpec.configure do |config|
  config.after(:suite) do
    $custom_headers = nil
  end
end

module RequestWithExtraHeaders
  def headers
    $custom_headers.each do |key, value|
      self.set_header "HTTP_#{key}", value
    end if $custom_headers

    super
  end
end
class ActionDispatch::Request
  prepend RequestWithExtraHeaders
end

Then in my specs:

/specs/features/something_spec.rb
...
$custom_headers = {"Referer" => referer_string}

After that, you can update ADT plugin after 20140702 version. This answer was intended for the ones starting from zero.

axios signature for post is axios.post(url[, data[, config]]). So you want to send params object within the third argument:

.post(`/mails/users/sendVerificationMail`, null, { params: {
  mail,
  firstname
}})
.then(response => response.status)
.catch(err => console.warn(err));

This will POST an empty body with the two query params:

POST http://localhost:8000/api/mails/users/sendVerificationMail?mail=lol%40lol.com&firstname=myFirstName

try like this

= IIF( MAX( iif( IsNothing(Fields!.Reading.Value ), -1, Fields!.Reading.Value ) ) = -1, "",  FormatNumber(  MAX( iif( IsNothing(Fields!.Reading.Value ), -1, Fields!.Reading.Value ), "CellReading_Reading"),3)) )

The following code did it for me to make a shadow inset of the right side:

-moz-box-shadow: inset -10px 0px 10px -10px #000;
-webkit-box-shadow: inset -10px 0px 10px -10px #000;
box-shadow: inset -10px 0px 10px -10px #000;

Hope it will help!!!!

apparently it's bound to an int, which is 0x7FFFFFFF (2147483647).

I'll use find command

find / -maxdepth 2 -iname 'tmp' -type d

as non superuser for the demo. It should complain 'Permission denied' when acessing / dir.

#!/bin/bash

echo "terminal:"
{ err="$(find / -maxdepth 2 -iname 'tmp' -type d 2>&1 1>&3 3>&- | tee /dev/stderr)"; } 3>&1 | tee /dev/fd/4 2>&1; out=$(cat /dev/fd/4)
echo "stdout:" && echo "$out"
echo "stderr:" && echo "$err"

that gives output:

terminal:
find: ‘/root’: Permission denied
/tmp
/var/tmp
find: ‘/lost+found’: Permission denied
stdout:
/tmp
/var/tmp
stderr:
find: ‘/root’: Permission denied
find: ‘/lost+found’: Permission denied

The terminal output has also /dev/stderr content the same way as if you were running that find command without any script. $out has /dev/stdout and $err has /dev/stderr content.

use:

#!/bin/bash

echo "terminal:"
{ err="$(find / -maxdepth 2 -iname 'tmp' -type d 2>&1 1>&3 3>&-)"; } 3>&1 | tee /dev/fd/4; out=$(cat /dev/fd/4)
echo "stdout:" && echo "$out"
echo "stderr:" && echo "$err"

if you don't want to see /dev/stderr in the terminal output.

terminal:
/tmp
/var/tmp
stdout:
/tmp
/var/tmp
stderr:
find: ‘/root’: Permission denied
find: ‘/lost+found’: Permission denied

<div style="display: inline">Is this what you meant?</div>

Using a return will stop the function and return undefined, or the value that you specify with the return command.

function myfunction(){
    if(a=="stop"){
        //return undefined;
        return; /** Or return "Hello" or any other value */
    }
}

Controller:

return redirect()->route('subscriptions.index')->withSuccess(['Success Message here!']);

Blade

@if (session()->has('success'))
<div class="alert alert-success">
    @if(is_array(session('success')))
        <ul>
            @foreach (session('success') as $message)
                <li>{{ $message }}</li>
            @endforeach
        </ul>
    @else
        {{ session('success') }}
    @endif
</div>
@endif

You can always save this part as separate blade file and include it easily. fore example:

<div class="row">
        <div class="col-md-6">
            @include('admin.system.success')
            <div class="box box-widget">

Use my example...

 public void createNotification() {
        NotificationManager notificationManager = (NotificationManager) 
              getSystemService(NOTIFICATION_SERVICE);
        Notification notification = new Notification(R.drawable.icon,
            "message", System.currentTimeMillis());
        // Hide the notification after its selected
        notification.flags |= Notification.FLAG_AUTO_CANCEL;
        Vibrator vibrator = (Vibrator)getSystemService(Context.VIBRATOR_SERVICE);
        long[] pattern = { 0, 100, 600, 100, 700};
        vibrator.vibrate(pattern, -1);
     Intent intent = new Intent(this, Main.class);
     PendingIntent activity = PendingIntent.getActivity(this, 0, intent, 0);
     String sms = getSharedPreferences("SMSPREF", MODE_PRIVATE).getString("incoming", "EMPTY");
        notification.setLatestEventInfo(this, "message" ,
            sms, activity);
        notification.number += 1;
        notificationManager.notify(0, notification);

      }

"FirstRow" Is a restriction and therefor it's place in the where clause not in the select clause. And it's called rownum

select * from dual where rownum = 1;

for (Iterator<String> iter = list.listIterator(); iter.hasNext(); ) {
    String a = iter.next();
    if (...) {
        iter.remove();
    }
}

Making an additional assumption that the list is of strings. As already answered, an list.iterator() is needed. The listIterator can do a bit of navigation too.

To specify a directory to search for (binary) libraries, you just use -L:

-L/data[...]/lib

To specify the actual library name, you use -l:

-lfoo  # (links libfoo.a or libfoo.so)

To specify a directory to search for include files (different from libraries!) you use -I:

-I/data[...]/lib

So I think what you want is something like

g++ -g -Wall -I/data[...]/lib testing.cpp fileparameters.cpp main.cpp -o test

These compiler flags (amongst others) can also be found at the GNU GCC Command Options manual:

• 3.16 Options for Directory Search

This is what I was looking for when googling this:

[{a: 1}, {b: 2}].reduce({}) { |h, v| h.merge v } => {:a=>1, :b=>2}

only variable/object declaration statement are written outside of method

public class details{
    public static void main(String arg[]){
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("What is your name?");
        String name = in.readLine(); ;
        System.out.println("Hello " + name);
    }
}

here is example try to learn java book and see the syntax then try to develop the program

If you're treating it as a tuple (see section 3.3.3 of the language spec), then:

var t:[number, string] = [1, "message"]

or

interface NumberStringTuple extends Array<string|number>{0:number; 1:string}
var t:NumberStringTuple = [1, "message"];

The best way is to simply reset the password by connecting with a domain/local admin (so you may need help from your system administrators), but this only works if SQL Server was set up to allow local admins (these are now left off the default admin group during setup).

If you can't use this or other existing methods to recover / reset the SA password, some of which are explained here:

• Disaster Recovery: What to do when the SA account password is lost in SQL Server 2005
• Is there a way I can retrieve sa password in sql server 2005
• How to recover SA password on Microsoft SQL Server 2008 R2

Then you could always backup your important databases, uninstall SQL Server, and install a fresh instance.

You can also search for less scrupulous ways to do it (e.g. there are password crackers that I am not enthusiastic about sharing).

As an aside, the login properties for sa would never say Windows Authentication. This is by design as this is a SQL Authentication account. This does not mean that Windows Authentication is disabled at the instance level (in fact it is not possible to do so), it just doesn't apply for a SQL auth account.

I wrote a tip on using PSExec to connect to an instance using the NT AUTHORITY\SYSTEM account (which works < SQL Server 2012), and a follow-up that shows how to hack the SqlWriter service (which can work on more modern versions):

• Recover access to a SQL Server instance
• More on Recovering Access to a SQL Server Instance

And some other resources:

• Connect to SQL Server When System Administrators Are Locked Out

• Leveraging Service SIDs to Logon to SQL Server Instances with Sysadmin Privileges

The closures are a way to execute code in the context it was created in.

What this means for concurency is that you can define variables, then initiate a nonblocking I/O function, and send it an anonymous function for its callback.

When the task is complete, the callback function will execute in the context with the variables, this is the closure.

The reason closures are so good for writing applications with nonblocking I/O is that it's very easy to manage the context of functions executing asynchronously.

I wanted to return all the states to the previous state (without reloading) including the elements added by jquery. The above implementation not gonna works. and I did as follows.

// Set initial HTML description
var defaultHTML;
function DefaultSave() {
  defaultHTML = document.body.innerHTML;
}
// Restore HTML description to initial state
function HTMLRestore() {
  document.body.innerHTML = defaultHTML;
}



DefaultSave()
<input type="button" value="Restore" onclick="HTMLRestore()">

I just posted this to my brand spanking new blog: http://jasonturim.wordpress.com/2013/09/01/angularjs-drag-and-drop/

Code here: https://github.com/logicbomb/lvlDragDrop

Demo here: http://logicbomb.github.io/ng-directives/drag-drop.html

Here are the directives these rely on a UUID service which I've included below:

var module = angular.module("lvl.directives.dragdrop", ['lvl.services']);

module.directive('lvlDraggable', ['$rootScope', 'uuid', function($rootScope, uuid) {
        return {
            restrict: 'A',
            link: function(scope, el, attrs, controller) {
                console.log("linking draggable element");

                angular.element(el).attr("draggable", "true");
                var id = attrs.id;
                if (!attrs.id) {
                    id = uuid.new()
                    angular.element(el).attr("id", id);
                }

                el.bind("dragstart", function(e) {
                    e.dataTransfer.setData('text', id);

                    $rootScope.$emit("LVL-DRAG-START");
                });

                el.bind("dragend", function(e) {
                    $rootScope.$emit("LVL-DRAG-END");
                });
            }
        }
    }]);

module.directive('lvlDropTarget', ['$rootScope', 'uuid', function($rootScope, uuid) {
        return {
            restrict: 'A',
            scope: {
                onDrop: '&'
            },
            link: function(scope, el, attrs, controller) {
                var id = attrs.id;
                if (!attrs.id) {
                    id = uuid.new()
                    angular.element(el).attr("id", id);
                }

                el.bind("dragover", function(e) {
                  if (e.preventDefault) {
                    e.preventDefault(); // Necessary. Allows us to drop.
                  }

                  e.dataTransfer.dropEffect = 'move';  // See the section on the DataTransfer object.
                  return false;
                });

                el.bind("dragenter", function(e) {
                  // this / e.target is the current hover target.
                  angular.element(e.target).addClass('lvl-over');
                });

                el.bind("dragleave", function(e) {
                  angular.element(e.target).removeClass('lvl-over');  // this / e.target is previous target element.
                });

                el.bind("drop", function(e) {
                  if (e.preventDefault) {
                    e.preventDefault(); // Necessary. Allows us to drop.
                  }

                  if (e.stopPropagation) {
                    e.stopPropagation(); // Necessary. Allows us to drop.
                  }
                    var data = e.dataTransfer.getData("text");
                    var dest = document.getElementById(id);
                    var src = document.getElementById(data);

                    scope.onDrop({dragEl: src, dropEl: dest});
                });

                $rootScope.$on("LVL-DRAG-START", function() {
                    var el = document.getElementById(id);
                    angular.element(el).addClass("lvl-target");
                });

                $rootScope.$on("LVL-DRAG-END", function() {
                    var el = document.getElementById(id);
                    angular.element(el).removeClass("lvl-target");
                    angular.element(el).removeClass("lvl-over");
                });
            }
        }
    }]);

UUID service

angular
.module('lvl.services',[])
.factory('uuid', function() {
    var svc = {
        new: function() {
            function _p8(s) {
                var p = (Math.random().toString(16)+"000000000").substr(2,8);
                return s ? "-" + p.substr(0,4) + "-" + p.substr(4,4) : p ;
            }
            return _p8() + _p8(true) + _p8(true) + _p8();
        },

        empty: function() {
          return '00000000-0000-0000-0000-000000000000';
        }
    };

    return svc;
});

You may have to use urlencode on the string 'http://google.com/?var=234&key=234'

Do I really have to first convert it into an array of arrays of key-value pairs?

No, an iterator of key-value pair arrays is enough. You can use the following to avoid creating the intermediate array:

function* entries(obj) {
    for (let key in obj)
        yield [key, obj[key]];
}

const map = new Map(entries({foo: 'bar'}));
map.get('foo'); // 'bar'

I faced the same issue recently and I created a small github project that contains a new mysql function UNIX_TIMESTAMP_MS() that returns the current timestamp in milliseconds.

Also you can do the following :

SELECT UNIX_TIMESTAMP_MS(NOW(3)) or SELECT UNIX_TIMESTAMP_MS(DateTimeField)

The project is located here : https://github.com/silviucpp/unix_timestamp_ms

To compile you need to Just run make compile in the project root.

Then you need to only copy the shared library in the /usr/lib/mysql/plugin/ (or whatever the plugin folder is on your machine.)

After this just open a mysql console and run :

CREATE FUNCTION UNIX_TIMESTAMP_MS RETURNS INT SONAME 'unix_timestamp_ms.so';

I hope this will help, Silviu

Since Java 8 you can use lambdas and achieve shorter code:

File dir = new File(xmlFilesDirectory);
File[] files = dir.listFiles((d, name) -> name.endsWith(".xml"));

I haven't seen this specific problem, but you may get better results with Eclipse Helios or Indigo. Galileo is getting old and is unlikely to be tested as much as the more recent Eclipse platforms.

I know I'm late to the party but just wanted to mention that the Jumpout II theme really is amazing.. I have a lot of themes and this one really is great for a # of reasons..

1. it handles glare very well (yes even pure black on matte screens can produce glare, unfortunately my new matte monitor - has a more "glary" coating than my old one).. this is a grayish-black background

2. it has enough colors that you can easily see read even dense code - some themes that look nice at first use too much of one color and it makes dense code harder to digest

3. the comments are all gray, this is even better than dark green which is my 2nd favorite choice.. it really helps the code pop out..

so basically this is a great anti-glare, anti-dense-code theme

honorable mentions (I think these all can be found on that same site, although I'm not sure I spelled all of them correctly)

1. Dark Flash Builder (really great but at first the use of red can be confusing, but it is really one of its strengths. I had to modify it to make my error text highlighting different - I settled on some bright red underlined text)
2. Gedit Original Oblivion
3. Leone Dark II
4. Visual Studio 2013
5. Retta (very halloweeny)

and for white / beige / blue (in that order)

1. Oughsumm (wow best white ever, possibly the most legible theme I've ever seen - however, white is too bright for me in my current office situation, although occasionally I do switch to this when I want to quickly review a lot of code before a commit), also it is comfortably legible at 1 point smaller than all dark themes I've used.
2. humane-ist
3. rubyblue

p.s. please note I change the font of all the themes I use to Consolas 11 or 12 depending on the monitor. Consolas I find to be the best programming font out there. It looks great, easy to read and very well suited to LCD anti-aliasing. I tried so many programming fonts but I always come back to this one quickly. And it is not too narrow.. I'm not in the narrow camp, I believe narrow font aficionados don't program with ultra wide monitors - maybe program on a macbook or something just as bad :)

p.p.s I know solarized is supposed to be some kind of ultimate, magical, life-enhancing nirvana-inducing theme but I just don't get it.. I tried but failed to find it anything but annoying

InputStream URLcontent = (InputStream) new URL(url).getContent();
Drawable image = Drawable.createFromStream(URLcontent, "your source link");

this has worked for me

One more alternative is to place one of the subviews inside of an HStack and place a Spacer() after it:

struct ContentView : View {
    var body: some View {
        VStack(alignment: .leading) {

            HStack {
                Text("Title")
                    .font(.title)
                    .background(Color.yellow)
                Spacer()
            }

            Text("Content")
                .lineLimit(nil)
                .font(.body)
                .background(Color.blue)

            Spacer()
            }

            .background(Color.red)
    }
}

resulting in :

You can zip the list with itself sans the first element:

a = [5, 7, 11, 4, 5]

for previous, current in zip(a, a[1:]):
    print(previous, current)

This works even if your list has no elements or only 1 element (in which case zip returns an empty iterable and the code in the for loop never executes). It doesn't work on generators, only sequences (tuple, list, str, etc).

Daniel Imms answer is excellent in regards to applying your CSS rotation to an inner element. However, it is possible to accomplish the end goal in a way that does not require JavaScript and works with longer strings of text.

Typically the whole reason to have vertical text in the first table column is to fit a long line of text in a short horizontal space and to go alongside tall rows of content (as in your example) or multiple rows of content (which I'll use in this example).

By using the ".rotate" class on the parent TD tag, we can not only rotate the inner DIV, but we can also set a few CSS properties on the parent TD tag that will force all of the text to stay on one line and keep the width to 1.5em. Then we can use some negative margins on the inner DIV to make sure that it centers nicely.

One thing to keep in mind with this solution is that it does not work well if the height of the row (or spanned rows) is shorter than the vertical text in the first column. It works best if you're spanning multiple rows or you have a lot of content creating tall rows.

Have fun playing around with this on jsFiddle.

Assuming here you're referring to the javax.inject.Inject annotation. @Inject is part of the Java CDI (Contexts and Dependency Injection) standard introduced in Java EE 6 (JSR-299), read more. Spring has chosen to support using the @Inject annotation synonymously with their own @Autowired annotation.

So, to answer your question, @Autowired is Spring's own annotation. @Inject is part of a Java technology called CDI that defines a standard for dependency injection similar to Spring. In a Spring application, the two annotations works the same way as Spring has decided to support some JSR-299 annotations in addition to their own.

While I myself would be waiting here for an answer, I wonder if it can be done via CSS:

@media only screen and (orientation:portrait){
#wrapper {width:1024px}
}

@media only screen and (orientation:landscape){
#wrapper {width:1024px}
}

Object is a collection of methods and variables.You can't print the variables in object by just cout operation . if you want to show the things inside the object you have to declare either a getter or a display text method in class.

ex

#include <iostream>

using namespace std;

class mystruct

{
private:
    int m_a;
    float m_b;

public:
    mystruct(int x, float y)
    {
            m_a = x;
            m_b = y;
    }
    public:
    void getm_aAndm_b()
    {
        cout<<m_a<<endl;
        cout<<m_b<<endl;
    }



};

int main()
{

    mystruct m = mystruct(5,3.14);

    cout << "my structure " << endl;
    m.getm_aAndm_b();
    return 0;

}

Not that this is just a one way of doing it

I prefer using Simple Storage:

// For document file
val documentFile = DocumentFileCompat.fromUri(context, uri)
val path = documentFile.absolutePath // e.g. /storage/emulated/0/Music/Torisetsu.mp3

// For media file
val mediaFile = MediaFile(context, uri)
val path = mediaFile.absolutePath // e.g. /storage/emulated/0/Music/My Love.mp3

To check whether the URI is media file or document file, use isMediaDocument extension function:

val isMediaFile = uri.isMediaDocument

If you have a fixed height in your container, you can set line-height to be the same as height, and it will center vertically. Then just add text-align to center horizontally.

Here's an example: http://jsfiddle.net/Cthulhu/QHEnL/1/

EDIT

Your code should look like this:

.img_thumb {
    float: left;
    height: 120px;
    margin-bottom: 5px;
    margin-left: 9px;
    position: relative;
    width: 147px;
    background-color: rgba(0, 0, 0, 0.5);
    border-radius: 3px;
    line-height:120px;
    text-align:center;
}

.img_thumb img {
    vertical-align: middle;
}

The images will always be centered horizontally and vertically, no matter what their size is. Here's 2 more examples with images with different dimensions:

UPDATE

It's now 2016 (the future!) and looks like a few things are changing (finally!!).

Back in 2014, Microsoft announced that it will stop supporting IE8 in all versions of Windows and will encourage all users to update to IE11 or Edge. Well, this is supposed to happen next Tuesday (12th January).

Why does this matter? With the announced death of IE8, we can finally start using CSS3 magic.

With that being said, here's an updated way of aligning elements, both horizontally and vertically:

.container {
    position: relative;
}

.container .element {
   position: absolute;
   left: 50%;
   top: 50%;
   transform: translate(-50%, -50%);
}

Using this transform: translate(); method, you don't even need to have a fixed height in your container, it's fully dynamic. Your element has fixed height or width? Your container as well? No? It doesn't matter, it will always be centered because all centering properties are fixed on the child, it's independent from the parent. Thank you CSS3.

If you only need to center in one dimension, you can use translateY or translateX. Just try it for a while and you'll see how it works. Also, try to change the values of the translate, you will find it useful for a bunch of different situations.

Here, have a new fiddle: https://jsfiddle.net/Cthulhu/1xjbhsr4/

For more information on transform, here's a good resource.

Happy coding.

- First to me Iterating and Looping are 2 different things.

Eg: Increment a variable till 5 is Looping.

    int count = 0;

    for (int i=0 ; i<5 ; i++){

        count = count + 1;

   }

Eg: Iterate over the Array to print out its values, is about Iteration

    int[] arr = {5,10,15,20,25};

    for (int i=0 ; i<arr.length ; i++){

        System.out.println(arr[i]);

   }

Now about all the Loops:

- Its always better to use For-Loop when you know the exact nos of time you gonna Loop, and if you are not sure of it go for While-Loop. Yes out there many geniuses can say that it can be done gracefully with both of them and i don't deny with them...but these are few things which makes me execute my program flawlessly...

For Loop :

int sum = 0; 

for (int i = 1; i <= 100; i++) {

  sum += i; 

}

 System.out.println("The sum is " + sum);

The Difference between While and Do-While is as Follows :

- While is a Entry Control Loop, Condition is checked in the Beginning before entering the loop.

- Do-While is a Exit Control Loop, Atleast once the block is always executed then the Condition is checked.

While Loop :

int sum = 0; 
int i = 0;       // i is 0 Here

    while (i<100) {

      sum += i; 
      i++;

    }

  System.out.println("The sum is " + sum);

do-While :

int sum = 0; 
int i = 0;      // i is 0 Here

    do{ 

      sum += i; 
       i++
    }while(i < 100; );

     System.out.println("The sum is " + sum);

From Java 5 we also have For-Each Loop to iterate over the Collections, even its handy with Arrays.

ArrayList<String> arr = new ArrayList<String>();

arr.add("Vivek");
arr.add("Is");
arr.add("Good");
arr.add("Boy");

for (String str : arr){         // str represents the value in each index of arr

    System.out.println(str);     

 }

Checkout intent properties like no history , clear back stack etc ... Intent.setFlags

Intent mStartActivity = new Intent(HomeActivity.this, SplashScreen.class);
int mPendingIntentId = 123456;
PendingIntent mPendingIntent = PendingIntent.getActivity(HomeActivity.this, mPendingIntentId, mStartActivity,
PendingIntent.FLAG_CANCEL_CURRENT);
AlarmManager mgr = (AlarmManager) HomeActivity.this.getSystemService(Context.ALARM_SERVICE);
mgr.set(AlarmManager.RTC, System.currentTimeMillis() + 100, mPendingIntent);
System.exit(0);

CREATE TABLE newTable LIKE oldTable;

Then, to copy the data over

INSERT INTO newTable SELECT * FROM oldTable;

I didn't find here solution for large arrays when flattening is not deep. So, my version:

function flatten(arr){
    result = []
    for (e of arr)
        result.push(...e)
    return result
}

I was playing with this and came up with an alternative.

$ VAR=/home/me/mydir/file.c

$ DIR=`echo $VAR |xargs dirname`

$ echo $DIR
/home/me/mydir

The part I liked is it was easy to extend backup the tree:

$ DIR=`echo $VAR |xargs dirname |xargs dirname |xargs dirname`

$ echo $DIR
/home

I also faced this issue. I was having JDK 1.8.0_121. I upgraded JDK to 1.8.0_181 and it worked like a charm.

Use the not function instead:

var lastOpenSite = $(this).siblings().not('.closedTab');

hasClass only tests whether an element has a class, not will remove elements from the selected set matching the provided selector.

[
      {
           id : '1',
           title: 'sample title',
           ....
      },
      {
           id : '2',
           title: 'sample title',
           ....
     },
      ...
 ]

Check Easy code for this output

 Gson gson=new GsonBuilder().create();
                List<Post> list= Arrays.asList(gson.fromJson(yourResponse.toString,Post[].class));

Here's what I was able to use in a VBscript to detect Office 64bit Outlook:

Dim WshShell, blnOffice64, strOutlookPath
Set WshShell = WScript.CreateObject("WScript.Shell")
blnOffice64=False
strOutlookPath=WshShell.RegRead("HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\outlook.exe\Path")
If WshShell.ExpandEnvironmentStrings("%PROCESSOR_ARCHITECTURE%") = "AMD64" And _
    not instr(strOutlookPath, "x86") > 0 then 
  blnOffice64=True
  wscript.echo "Office 64"
End If

In likeness of how I found this question using Google, I wanted to take it one step further. Lets say I have a string[] states and a db Entity of StateCounties and I just want the states from the list returned and not all of the StateCounties.

I would write:

db.StateCounties.Where(x => states.Any(s => x.State.Equals(s))).ToList();

I found this within the sample of CheckBoxList for nu-get.

Read it and weep!

I figured it out. If you don't throw from the handler, the handler will just continue and so will the exception.

The magic happens when you throw you own exception and handle that.

#include "stdafx.h"
#include <stdio.h>
#include <stdlib.h>
#include <signal.h>
#include <tchar.h>

void SignalHandler(int signal)
{
    printf("Signal %d",signal);
    throw "!Access Violation!";
}

int main()
{
    typedef void (*SignalHandlerPointer)(int);

    SignalHandlerPointer previousHandler;
    previousHandler = signal(SIGSEGV , SignalHandler);
    try{
        *(int *) 0 = 0;// Baaaaaaad thing that should never be caught. You should write good code in the first place.
    }
    catch(char *e)
    {
        printf("Exception Caught: %s\n",e);
    }
    printf("Now we continue, unhindered, like the abomination never happened. (I am an EVIL genius)\n");
    printf("But please kids, DONT TRY THIS AT HOME ;)\n");

}

There is an operator just for this. For example, if I wanted to change a variable i by 3 then:

var someValue = 9;
var Increment  = 3;
for(var i=0;i<someValue;i+=Increment){
//do whatever
}

var someValue = 3;
var Increment  = 3;
for(var i=9;i>someValue;i+=Increment){
//do whatever
}

To do it without using a JavaScript library such as jQuery, you'd do it like this:

var span = document.getElementById("myspan"),
    text = document.createTextNode(''+intValue);
span.innerHTML = ''; // clear existing
span.appendChild(text);

If you do want to use jQuery, it's just this:

$("#myspan").text(''+intValue);

you can use the '{}' to access you property, and then you can do as you wish. Save it or display the content.

    $varName = $xml->{'key'};

From your example her's the code

        $filePath = __DIR__ . 'Your path ';
        $fileName = 'YourFilename.xml';

        if (file_exists($filePath . $fileName)) {
            $xml = simplexml_load_file($filePath . $fileName);
            $mainNode = $xml->{'code'};

            $cityArray = array();

            foreach ($mainNode as $key => $data)        {
               $cityArray[..] = $mainNode[$key]['cityCode'];
               ....

            }     

        }

To concatenate multiple pyspark dataframes into one:

from functools import reduce

reduce(lambda x,y:x.union(y), [df_1,df_2])

And you can replace the list of [df_1, df_2] to a list of any length.

You already have a process bound to the default port (8000). If you already ran the same module before, it is most likely that process still bound to the port. Try and locate the other process first:

$ ps -fA | grep python
  501 81651 12648   0  9:53PM ttys000    0:00.16 python -m SimpleHTTPServer

The command arguments are included, so you can spot the one running SimpleHTTPServer if more than one python process is active. You may want to test if http://localhost:8000/ still shows a directory listing for local files.

The second number is the process number; stop the server by sending it a signal:

kill 81651

This sends a standard SIGTERM signal; if the process is unresponsive you may have to resort to tougher methods like sending a SIGKILL (kill -s KILL <pid> or kill -9 <pid>) signal instead. See Wikipedia for more details.

Alternatively, run the server on a different port, by specifying the alternative port on the command line:

$ python -m SimpleHTTPServer 8910
Serving HTTP on 0.0.0.0 port 8910 ...

then access the server as http://localhost:8910; where 8910 can be any number from 1024 and up, provided the port is not already taken.

a bit more convoluted solution that fully matches your spec

echo `expr $FILENAME : '\(.*\)\.[^.]*'`_`date +%d-%m-%y`.`expr $FILENAME : '.*\.\([^.]*\)'`

where first 'expr' extracts file name without extension, second 'expr' extracts extension

You might just have to install the packages.

yum install php-pdo php-mysqli

After they're installed, restart Apache.

httpd restart

or

apachectl restart

template <class outType, class inType>
outType safe_cast(inType pointer)
{
    void* temp = static_cast<void*>(pointer);
    return static_cast<outType>(temp);
}

I tried to conclude and wrote a simple safe cast using templates. Note that this solution doesn't guarantee to cast pointers on a functions.

Install Postman native app, Chrome extension has been deprecated. (Mine was opening in own window but still ran as Chrome app)

To close a windows form (System.Windows.Forms.Form) when one of its button is clicked: in Visual Studio, open the form in the designer, right click on the button and open its property page, then select the field DialogResult an set it to OK or the appropriate value.

Using code like this in a form I can capture the original source upload filename, copy it to a second simple input field. This is so user can provide an alternate upload filename in submit request since the file upload filename is immutable.

    <input type="file" id="imgup1" name="imagefile">
      onchange="document.getElementsByName('imgfn1')[0].value = document.getElementById('imgup1').value;">
    <input type="text" name="imgfn1" value="">

It looks like you indented so_far = new too much. Try this:

if guess in word:
    print("\nYes!", guess, "is in the word!")

    # Create a new variable (so_far) to contain the guess
    new = ""
    i = 0
    for i in range(len(word)):
        if guess == word[i]:
            new += guess
        else:
            new += so_far[i]
    so_far = new # unindented this

See Microsofts JavaScriptSerializer

The JavaScriptSerializer class is used internally by the asynchronous communication layer to serialize and deserialize the data that is passed between the browser and the Web server. You cannot access that instance of the serializer. However, this class exposes a public API. Therefore, you can use the class when you want to work with JavaScript Object Notation (JSON) in managed code.

Namespace: System.Web.Script.Serialization

Assembly: System.Web.Extensions (in System.Web.Extensions.dll)

You can use an infinite loop to achieve this:

do
  read -p "Enter password" passwd
  case "$passwd" in
    <some good condition> ) break;;
  esac
done

You can have multiple registries for scoped packages in your .npmrc file. For example:

@polymer:registry=<url register A>
registry=http://localhost:4873/

Packages under @polymer scope will be received from https://registry.npmjs.org, but the rest will be received from your local NPM.

React Router 4 includes a withRouter HOC that gives you access to the history object via this.props:

import React, {Component} from 'react'
import {withRouter} from 'react-router-dom'

class Foo extends Component {
  constructor(props) {
    super(props)

    this.goHome = this.goHome.bind(this)
  }

  goHome() {
    this.props.history.push('/')
  }

  render() {
    <div className="foo">
      <button onClick={this.goHome} />
    </div>
  }
}

export default withRouter(Foo)

For those of you who don't want to create a bat file to edit for every project, or dont want to remember all the commands associated with the keytools and jarsigner programs and just want to get it done in one process use this program:

http://lukealderton.com/projects/programs/android-apk-signer-aligner.aspx

I built it because I was fed up with the lengthy process of having to type all the file locations every time.

This program can save your configuration so the next time you start it, you just need to hit Generate an it will handle it for you. That's it.

No install required, it's completely portable and saves its configurations in a CSV in the same folder.

If it's not a local application powered by JavaScript with full access permissions, you can't get the size of any file just from the path name. Web pages running javascript do not have access to the local filesystem for security reasons.

You can use a graceful degrading file uploader like SWFUpload if you want to show a progress bar. HTML5 also has the File API, but that is not widely supported just yet. If a user selects the file for an input[type=file] element, you can get details about the file from the files collection:

alert(myInp.files[0].size);

Why write complicated code when you could make it simple?

Indeed, if you are absolutely going to use the Optional class, the most simple code is what you have already written ...

if (user.isPresent())
{
    doSomethingWithUser(user.get());
}

This code has the advantages of being

1. readable
2. easy to debug (breakpoint)
3. not tricky

Just because Oracle has added the Optional class in Java 8 doesn't mean that this class must be used in all situation.

if a method is not static, that "tells" the compiler that the method requires access to instance-level data in the class, (like a non-static field). This data would not be available unless an instance of the class has been created. So the compiler throws an error if you try to call the method from a static method.. If in fact the method does NOT reference any non-static member of the class, make the method static.

In Resharper, for example, just creating a non-static method that does NOT reference any static member of the class generates a warning message "This method can be made static"

All of the above work, but also have to work around a problem (escapes and special characters) that doesn't need to occur in the first place: Special characters when the variable is expanded by the shell. Just don't do that (variable expansion) in the first place. Use the variable directly, without expansion.

Also, if your variable contains a secret and you want to copy that secret into a file, you might want to not have expansion in the command line as tracing/command echo of the shell commands might reveal the secret. Means, all answers which use $var in the command line may have a potential security risk by exposing the variable contents to tracing and logging of the shell.

Use this:

printenv var >file

That means, in case of the OP question:

printenv var >"$destfile"

Note: variable names are case sensitive.

Quick Command for Finding Date/Time Metadata in Many Video Files

The following command has served me well in finding date/time metadata on various AVI/MP4 videos:

ffmpeg -i /path/to/video.mp4 -dump

Note: as mentioned in other answers, there is no guarantee that such information is available in all video files or available in a specific format.

declare @i int  = (SELECT ISNULL(MAX(interfaceID),0) + 1 FROM prices)


update prices
set interfaceID  = @i , @i = @i + 1
where interfaceID is null

should do the work

Assuming your WebSocket server is listening on the same port as from which the page is being requested, I would suggest:

function createWebSocket(path) {
    var protocolPrefix = (window.location.protocol === 'https:') ? 'wss:' : 'ws:';
    return new WebSocket(protocolPrefix + '//' + location.host + path);
}

Then, for your case, call it as follows:

var socket = createWebSocket(location.pathname + '/to/ws');

Thanks Shuwaiee

I made a slight change though as using it in a Private Sub already.

Dim GetIPAddress()

Dim strHostName As String

Dim strIPAddress As String

strHostName = System.Net.Dns.GetHostName()

strIPAddress = System.Net.Dns.GetHostByName(strHostName).AddressList(0).ToString()

MessageBox.Show("Host Name: " & strHostName & vbCrLf & "IP Address: " & strIPAddress)

But also made a change to the way the details are displayed so that they can show on seperate lines using & vbCrLf &

MessageBox.Show("Host Name: " & strHostName & vbCrLf & "IP Address: " & strIPAddress)

Hope this helps someone.

If you are using this in the Reflection C#, you can get the guid from the property attribute as follows

var propertyAttributes= property.GetCustomAttributes();
foreach(var attribute in propertyAttributes)
{
  var myguid= Guid.Parse(attribute.Id.ToString());
}

Wrap your image with a span element with a black background.

.img-wrapper {
  display: inline-block;
  background: #000;
}

.item-fade {
  vertical-align: top;
  transition: opacity 0.3s;
  -webkit-transition: opacity 0.3s;
  opacity: 1;
}

.item-fade:hover {
  opacity: 0.2;
}

<span class="img-wrapper">
   <img class="item-fade" src="http://placehold.it/100x100/cf5" />
</span>

I believe this regex handles more situations:

/(\b\S+\b)\s+\b\1\b/

A good selection of test strings can be found here: http://callumacrae.github.com/regex-tuesday/challenge1.html

It sounds very much like you're using an array to store different fields. This is definitely a code smell. I'd avoid using arrays as much as possible as they're generally not suitable (or needed) in high-level code.

Switching to a simple Dictionary may be a workable option in the short term. As would using a big property bag class. There are lots of options. The problem you have now is just a symptom of bad design, you should look at fixing the underlying problem rather than just patching the bad design so it kinda, sorta mostly works, for now.

Just a reminder on adding columns. If one of the values is NULL the total of those columns becomes NULL. Thus why some posters have recommended coalesce with the second parameter being 0

I know this was an older posting but wanted to add this for completeness.

You have to pass a function that accepts two parameters, compares them, and returns a number, so assuming you wanted to sort them by ID you would write...

objArray.sort(function(a,b) {
    return a.id-b.id;
});
// objArray is now sorted by Id

You can use jquery-rss or Vanilla RSS, which comes with nice templating and is super easy to use:

// Example for jquery.rss
$("#your-div").rss("https://stackoverflow.com/feeds/question/10943544", {
    limit: 3,
    layoutTemplate: '<ul class="inline">{entries}</ul>',
    entryTemplate: '<li><a href="{url}">[{author}@{date}] {title}</a><br/>{shortBodyPlain}</li>'
})

// Example for Vanilla RSS
const RSS = require('vanilla-rss');
const rss = new RSS(
    document.querySelector("#your-div"),
    "https://stackoverflow.com/feeds/question/10943544",
    { 
      // options go here
    }
);
rss.render().then(() => {
  console.log('Everything is loaded and rendered');
});

See http://jsfiddle.net/sdepold/ozq2dn9e/1/ for a working example.

To print all lines in text file from command line (with delayedExpansion):

set input="path/to/file.txt"

for /f "tokens=* delims=[" %i in ('type "%input%" ^| find /v /n ""') do (
set a=%i
set a=!a:*]=]!
echo:!a:~1!)

Works with leading whitespace, blank lines, whitespace lines.

Tested on Win 10 CMD

INSERT INTO Table2 SELECT DISTINCT ID,Data = STUFF((SELECT ', ' + AA.Data FROM Table1 AS AA WHERE AA.ID = BB.ID FOR XML PATH(''), TYPE).value('.','nvarchar(max)'), 1, 2, '') FROM Table1 AS BB 
GROUP BY ID,Data
ORDER BY ID;

Here is a non-regex heap allocation friendly fast solution which was what I was looking for.

Unsafe edition.

public static unsafe void ToAlphaNumeric(ref string input)
{
    fixed (char* p = input)
    {
        int offset = 0;
        for (int i = 0; i < input.Length; i++)
        {
            if (char.IsLetterOrDigit(p[i]))
            {
                p[offset] = input[i];
                offset++;
            }
        }
        ((int*)p)[-1] = offset; // Changes the length of the string
        p[offset] = '\0';
    }
}

And for those who don't want to use unsafe or don't trust the string length hack.

public static string ToAlphaNumeric(string input)
{
    int j = 0;
    char[] newCharArr = new char[input.Length];

    for (int i = 0; i < input.Length; i++)
    {
        if (char.IsLetterOrDigit(input[i]))
        {
            newCharArr[j] = input[i];
            j++;
        }
    }

    Array.Resize(ref newCharArr, j);

    return new string(newCharArr);
}

I use:

from pathlib import Path
import platform
import tempfile

tempdir = Path("/tmp" if platform.system() == "Darwin" else tempfile.gettempdir())

This is because on MacOS, i.e. Darwin, tempfile.gettempdir() and os.getenv('TMPDIR') return a value such as '/var/folders/nj/269977hs0_96bttwj2gs_jhhp48z54/T'; it is one that I do not always want.

Lots of recommendation for CPAN.pm, which is great, but if you're using Perl 5.10 then you've also got access to CPANPLUS.pm which is like CPAN.pm but better.

And, of course, it's available on CPAN for people still using older versions of Perl. Why not try:

$ cpan CPANPLUS

Status Code 304 Not Modified would also make an acceptable response to a duplicate request. This is similar to processing a header of If-None-Match using an entity tag.

In my opinion, @Piskvor's answer is the more obvious choice to what I perceive is the intent of the original question, but I have an alternative that is also relevant.

If you want to treat a duplicate request as a warning or notification rather than as an error, a response status code of 304 Not Modified and Content-Location header identifying the existing resource would be just as valid. When the intent is merely to ensure that a resource exists, a duplicate request would not be an error but a confirmation. The request is not wrong, but is simply redundant, and the client can refer to the existing resource.

In other words, the request is good, but since the resource already exists, the server does not need to perform any further processing.

Sublime Text 3

Procedure

Run Sublime Text.

Select Preferences ? Package Control.

Or

Use ctrl+shift+p shortcut for (Win, Linux) or cmd+shift+p for (OS X).

Select Remove Package. Package Control: Remove Package

Start typing name of the package you want to remove and select it from the list of installed packages.

Wait for the uninstallation to complete.

You can do it like this:

postData[postData.length] = { name: "variable_name", value: variable_value };

You need to give required = false for name and password request parameters as well. That's because, when you provide just the logout parameter, it actually expects for name and password as well as they are still mandatory.

It worked when you just gave name and password because logout wasn't a mandatory parameter thanks to required = false already given for logout.

Maybe map the share as a network drive and then do

git clone Z:\

Mostly just a guess; I always do this stuff using ssh. Following that suggstion of course will mean that you'll need to have that drive mapped every time you push/pull to/from the laptop. I'm not sure how you rig up ssh to work under windows but if you're going to be doing this a lot it might be worth investigating.

If you need to handle DOM events not already provided by React you have to add DOM listeners after the component is mounted:

Update: Between React 13, 14, and 15 changes were made to the API that affect my answer. Below is the latest way using React 15 and ES7. See answer history for older versions.

class MovieItem extends React.Component {

  componentDidMount() {
    // When the component is mounted, add your DOM listener to the "nv" elem.
    // (The "nv" elem is assigned in the render function.)
    this.nv.addEventListener("nv-enter", this.handleNvEnter);
  }

  componentWillUnmount() {
    // Make sure to remove the DOM listener when the component is unmounted.
    this.nv.removeEventListener("nv-enter", this.handleNvEnter);
  }

  // Use a class arrow function (ES7) for the handler. In ES6 you could bind()
  // a handler in the constructor.
  handleNvEnter = (event) => {
    console.log("Nv Enter:", event);
  }

  render() {
    // Here we render a single <div> and toggle the "aria-nv-el-current" attribute
    // using the attribute spread operator. This way only a single <div>
    // is ever mounted and we don't have to worry about adding/removing
    // a DOM listener every time the current index changes. The attrs 
    // are "spread" onto the <div> in the render function: {...attrs}
    const attrs = this.props.index === 0 ? {"aria-nv-el-current": true} : {};

    // Finally, render the div using a "ref" callback which assigns the mounted 
    // elem to a class property "nv" used to add the DOM listener to.
    return (
      <div ref={elem => this.nv = elem} aria-nv-el {...attrs} className="menu_item nv-default">
        ...
      </div>
    );
  }

}

Example on Codepen.io

I set .navbar-brand { min-height: inherit } which solved the issue for me (thanks @creimers for inspiration).

Applying the full_extent() function in an answer by @Joe 3 years later from here, you can get exactly what the OP was looking for. Alternatively, you can use Axes.get_tightbbox() which gives a little tighter bounding box

import matplotlib.pyplot as plt
import matplotlib as mpl
import numpy as np
from matplotlib.transforms import Bbox

def full_extent(ax, pad=0.0):
    """Get the full extent of an axes, including axes labels, tick labels, and
    titles."""
    # For text objects, we need to draw the figure first, otherwise the extents
    # are undefined.
    ax.figure.canvas.draw()
    items = ax.get_xticklabels() + ax.get_yticklabels() 
#    items += [ax, ax.title, ax.xaxis.label, ax.yaxis.label]
    items += [ax, ax.title]
    bbox = Bbox.union([item.get_window_extent() for item in items])

    return bbox.expanded(1.0 + pad, 1.0 + pad)

# Make an example plot with two subplots...
fig = plt.figure()
ax1 = fig.add_subplot(2,1,1)
ax1.plot(range(10), 'b-')

ax2 = fig.add_subplot(2,1,2)
ax2.plot(range(20), 'r^')

# Save the full figure...
fig.savefig('full_figure.png')

# Save just the portion _inside_ the second axis's boundaries
extent = full_extent(ax2).transformed(fig.dpi_scale_trans.inverted())
# Alternatively,
# extent = ax.get_tightbbox(fig.canvas.renderer).transformed(fig.dpi_scale_trans.inverted())
fig.savefig('ax2_figure.png', bbox_inches=extent)

I resolved exact the problem when the service layer is using Visual Studio IIS Express. Just point to 10.0.2.2:port wont work. Instead of messing around the IIS Express as mentioned by other posts, I just put a proxy in front of the IIS Express. For example, apache or nginx. The nginx.conf will look like

 # Mobile API
 server { 
    listen       8090;
    server_name  default_server;

    location / {
        proxy_pass http://localhost:54722;
    }
  }

Then the android needs to points to my IP address as 192.168.x.x:8090

The technique I use for having percentage width of the parent is adding an extra spacer view in combination with some flexbox. This will not apply to all scenarios but it can be very helpful.

So here we go:

class PercentageWidth extends Component {
    render() {
        return (
            <View style={styles.container}>
                <View style={styles.percentageWidthView}>
                    {/* Some content */}
                </View>

                <View style={styles.spacer}
                </View>
            </View>
        );
    }
}

const styles = StyleSheet.create({
    container: {
        flexDirection: 'row'
    },

    percentageWidthView: {
        flex: 60
    },

    spacer: {
        flex: 40
    }
});

Basically the flex property is the width relative to the "total" flex of all items in the flex container. So if all items sum to 100 you have a percentage. In the example I could have used flex values 6 & 4 for the same result, so it's even more FLEXible.

If you want to center the percentage width view: add two spacers with half the width. So in the example it would be 2-6-2.

Of course adding the extra views is not the nicest thing in the world, but in a real world app I can image the spacer will contain different content.

You need to do:

alert($(this).attr('value'));
