You need to run Set-ExecutionPolicy:

Set-ExecutionPolicy Unrestricted <-- Will allow unsigned PowerShell scripts to run.

Set-ExecutionPolicy Restricted <-- Will not allow unsigned PowerShell scripts to run.

Set-ExecutionPolicy RemoteSigned <-- Will allow only remotely signed PowerShell scripts to run.

Try creating scriptfile as a separate command:

Command myCommand = new Command(scriptfile);

then you can add parameters with

CommandParameter testParam = new CommandParameter("key","value");
myCommand.Parameters.Add(testParam);

and finally

pipeline.Commands.Add(myCommand);

Here is the complete, edited code:

RunspaceConfiguration runspaceConfiguration = RunspaceConfiguration.Create();

Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConfiguration);
runspace.Open();

Pipeline pipeline = runspace.CreatePipeline();

//Here's how you add a new script with arguments
Command myCommand = new Command(scriptfile);
CommandParameter testParam = new CommandParameter("key","value");
myCommand.Parameters.Add(testParam);

pipeline.Commands.Add(myCommand);

// Execute PowerShell script
results = pipeline.Invoke();

The placeholder image you're including has a height of 50px. It is wrapped in an anchor (.navbar-brand) with a padding-top of 15px and a height of 50px. That's why the placeholder logo flows out of the bar. Try including a smaller image or play with the anchor's padding by assigning a class or an id to it wich you can reference in your css.

EDIT Or remove the static height: 50px from .navbar-brand. Your navbar will then take the height of its highest child.

h3 in bootstrap by default has a padding-top of 20px. Again, it is wrapped with that padding-top: 15px anchor. That's why it's not vertically centered like you want it. You could give the h3 a class or and id that resets the margin-top. And the same you could do with the padding of the anchor.

Here's something to play with: http://jsbin.com/jelec/1/edit?html,output

Yeah it suck to get stuck in Scale View.

Host+Home will popup the Virtual machine settings. (by default Host is Right Control)

From there you can change the view settings, as the Menu bar is hidden in Scale View.

Had the same issue, especially when you checked the box not to show the 'Switch to Scale view' dialog.

This you can do while the VM is running.

This answers in an extension to what avs099 has given above, for those who are still having problems:

1.Makesure that you have php_openssl.dll installed(else find it online and install it);

2.Go to your php.ini; find extension=php_openssl.dll enable it/uncomment

3.Go to github and downland the latetest version :6.0 at this time.

4.Extract the master copy into the path that works better for you(I recommend the same directory as the calling file)

Now copy this code into your foo-mailer.php and render it with your gmail stmp authentications.

    require("/PHPMailer-master/src/PHPMailer.php");
    require("/PHPMailer-master/src/SMTP.php");
    require("/PHPMailer-master/src/Exception.php");


    $mail = new PHPMailer\PHPMailer\PHPMailer();
    $mail->IsSMTP(); 

    $mail->CharSet="UTF-8";
    $mail->Host = "smtp.gmail.com";
    $mail->SMTPDebug = 1; 
    $mail->Port = 465 ; //465 or 587

     $mail->SMTPSecure = 'ssl';  
    $mail->SMTPAuth = true; 
    $mail->IsHTML(true);

    //Authentication
    $mail->Username = "[email protected]";

    //Set Params
    $mail->SetFrom("[email protected]");
    $mail->AddAddress("[email protected]");
    $mail->Subject = "Test";
    $mail->Body = "hello";


     if(!$mail->Send()) {
        echo "Mailer Error: " . $mail->ErrorInfo;
     } else {
        echo "Message has been sent";
     }

Disclaimer:The original owner of the code above is avs099 with just my little input.

Take note of the additional:

a) (PHPMailer\PHPMailer) namespace:needed for name conflict resolution.

b) The (require("/PHPMailer-master/src/Exception.php");):It was missing in avs099's code thus the problem encountered by aProgger,you need that line to tell the mailer class where the Exception class is located.

1. Create "root" package (folder) in your project, for example.

   package source; (.../path_to_project/source/)

2. Move YourClass.class into a source folder. (.../path_to_project/source/YourClass.class)

3. Import like this

   import source.YourClass;

ID's should be unique, so you should only use a particular ID once on a page. Classes may be used repeatedly.

No, this seems perfectly reasonable. There is a List<T>.AddRange() method that basically does just this, but requires your collection to be a concrete List<T>.

I ran into this problem as well and the the problem with simply hacking the close-button is that I still need access to the standard bootstrap alert-close events.

My solution was to write a small, customisable, jquery plugin that injects a properly formed Bootstrap 3 alert (with or without close button as you need it) with a minimum of fuss and allows you to easily regenerate it after the box is closed.

See https://github.com/davesag/jquery-bs3Alert for usage, tests, and examples.

In short \r has ASCII value 13 (CR) and \n has ASCII value 10 (LF). Mac uses CR as line delimiter (at least, it did before, I am not sure for modern macs), *nix uses LF and Windows uses both (CRLF).

create a list like :-

this.xyzlist = [
  {
    id: 1,
    value: 'option1'
  },
  {
    id: 2,
    value: 'option2'
  }
];

Html :-

<div class="checkbox" *ngFor="let list of xyzlist">
            <label>
              <input formControlName="interestSectors" type="checkbox" value="{{list.id}}" (change)="onCheckboxChange(list,$event)">{{list.value}}</label>
          </div>

then in it's component ts :-

onCheckboxChange(option, event) {
     if(event.target.checked) {
       this.checkedList.push(option.id);
     } else {
     for(var i=0 ; i < this.xyzlist.length; i++) {
       if(this.checkedList[i] == option.id) {
         this.checkedList.splice(i,1);
      }
    }
  }
  console.log(this.checkedList);
}

function(e){ e.preventDefault();

and its opposite

function(e){ return true; }

Seems to be possible with JQuery's ajax function by specifying

type: "put" or type: "delete"

and is not not supported by all browsers, but most of them.

Check out this question for more info on compatibility:

Are the PUT, DELETE, HEAD, etc methods available in most web browsers?

This method sucks, but I've left it here for reference so others avoid this path:

Using Option 1 from @ninjagecko worked best for me:

Array.prototype.equals = function(array) {
    return array instanceof Array && JSON.stringify(this) === JSON.stringify(array) ;
}

a = [1, [2, 3]]
a.equals([[1, 2], 3]) // false
a.equals([1, [2, 3]]) // true

It will also handle the null and undefined case, since we're adding this to the prototype of array and checking that the other argument is also an array.

Let me try to state the different viable modes of passing pointers around to objects whose memory is managed by an instance of the std::unique_ptr class template; it also applies to the the older std::auto_ptr class template (which I believe allows all uses that unique pointer does, but for which in addition modifiable lvalues will be accepted where rvalues are expected, without having to invoke std::move), and to some extent also to std::shared_ptr.

As a concrete example for the discussion I will consider the following simple list type

struct node;
typedef std::unique_ptr<node> list;
struct node { int entry; list next; }

Instances of such list (which cannot be allowed to share parts with other instances or be circular) are entirely owned by whoever holds the initial list pointer. If client code knows that the list it stores will never be empty, it may also choose to store the first node directly rather than a list. No destructor for node needs to be defined: since the destructors for its fields are automatically called, the whole list will be recursively deleted by the smart pointer destructor once the lifetime of initial pointer or node ends.

This recursive type gives the occasion to discuss some cases that are less visible in the case of a smart pointer to plain data. Also the functions themselves occasionally provide (recursively) an example of client code as well. The typedef for list is of course biased towards unique_ptr, but the definition could be changed to use auto_ptr or shared_ptr instead without much need to change to what is said below (notably concerning exception safety being assured without the need to write destructors).

Modes of passing smart pointers around

Mode 0: pass a pointer or reference argument instead of a smart pointer

If your function is not concerned with ownership, this is the preferred method: don't make it take a smart pointer at all. In this case your function does not need to worry who owns the object pointed to, or by what means that ownership is managed, so passing a raw pointer is both perfectly safe, and the most flexible form, since regardless of ownership a client can always produce a raw pointer (either by calling the get method or from the address-of operator &).

For instance the function to compute the length of such list, should not be give a list argument, but a raw pointer:

size_t length(const node* p)
{ size_t l=0; for ( ; p!=nullptr; p=p->next.get()) ++l; return l; }

A client that holds a variable list head can call this function as length(head.get()), while a client that has chosen instead to store a node n representing a non-empty list can call length(&n).

If the pointer is guaranteed to be non null (which is not the case here since lists may be empty) one might prefer to pass a reference rather than a pointer. It might be a pointer/reference to non-const if the function needs to update the contents of the node(s), without adding or removing any of them (the latter would involve ownership).

An interesting case that falls in the mode 0 category is making a (deep) copy of the list; while a function doing this must of course transfer ownership of the copy it creates, it is not concerned with the ownership of the list it is copying. So it could be defined as follows:

list copy(const node* p)
{ return list( p==nullptr ? nullptr : new node{p->entry,copy(p->next.get())} ); }

This code merits a close look, both for the question as to why it compiles at all (the result of the recursive call to copy in the initialiser list binds to the rvalue reference argument in the move constructor of unique_ptr<node>, a.k.a. list, when initialising the next field of the generated node), and for the question as to why it is exception-safe (if during the recursive allocation process memory runs out and some call of new throws std::bad_alloc, then at that time a pointer to the partly constructed list is held anonymously in a temporary of type list created for the initialiser list, and its destructor will clean up that partial list). By the way one should resist the temptation to replace (as I initially did) the second nullptr by p, which after all is known to be null at that point: one cannot construct a smart pointer from a (raw) pointer to constant, even when it is known to be null.

Mode 1: pass a smart pointer by value

A function that takes a smart pointer value as argument takes possession of the object pointed to right away: the smart pointer that the caller held (whether in a named variable or an anonymous temporary) is copied into the argument value at function entrance and the caller's pointer has become null (in the case of a temporary the copy might have been elided, but in any case the caller has lost access to the pointed to object). I would like to call this mode call by cash: caller pays up front for the service called, and can have no illusions about ownership after the call. To make this clear, the language rules require the caller to wrap the argument in std::move if the smart pointer is held in a variable (technically, if the argument is an lvalue); in this case (but not for mode 3 below) this function does what its name suggests, namely move the value from the variable to a temporary, leaving the variable null.

For cases where the called function unconditionally takes ownership of (pilfers) the pointed-to object, this mode used with std::unique_ptr or std::auto_ptr is a good way of passing a pointer together with its ownership, which avoids any risk of memory leaks. Nonetheless I think that there are only very few situations where mode 3 below is not to be preferred (ever so slightly) over mode 1. For this reason I shall provide no usage examples of this mode. (But see the reversed example of mode 3 below, where it is remarked that mode 1 would do at least as well.) If the function takes more arguments than just this pointer, it may happen that there is in addition a technical reason to avoid mode 1 (with std::unique_ptr or std::auto_ptr): since an actual move operation takes place while passing a pointer variable p by the expression std::move(p), it cannot be assumed that p holds a useful value while evaluating the other arguments (the order of evaluation being unspecified), which could lead to subtle errors; by contrast, using mode 3 assures that no move from p takes place before the function call, so other arguments can safely access a value through p.

When used with std::shared_ptr, this mode is interesting in that with a single function definition it allows the caller to choose whether to keep a sharing copy of the pointer for itself while creating a new sharing copy to be used by the function (this happens when an lvalue argument is provided; the copy constructor for shared pointers used at the call increases the reference count), or to just give the function a copy of the pointer without retaining one or touching the reference count (this happens when a rvalue argument is provided, possibly an lvalue wrapped in a call of std::move). For instance

void f(std::shared_ptr<X> x) // call by shared cash
{ container.insert(std::move(x)); } // store shared pointer in container

void client()
{ std::shared_ptr<X> p = std::make_shared<X>(args);
  f(p); // lvalue argument; store pointer in container but keep a copy
  f(std::make_shared<X>(args)); // prvalue argument; fresh pointer is just stored away
  f(std::move(p)); // xvalue argument; p is transferred to container and left null
}

The same could be achieved by separately defining void f(const std::shared_ptr<X>& x) (for the lvalue case) and void f(std::shared_ptr<X>&& x) (for the rvalue case), with function bodies differing only in that the first version invokes copy semantics (using copy construction/assignment when using x) but the second version move semantics (writing std::move(x) instead, as in the example code). So for shared pointers, mode 1 can be useful to avoid some code duplication.

Mode 2: pass a smart pointer by (modifiable) lvalue reference

Here the function just requires having a modifiable reference to the smart pointer, but gives no indication of what it will do with it. I would like to call this method call by card: caller ensures payment by giving a credit card number. The reference can be used to take ownership of the pointed-to object, but it does not have to. This mode requires providing a modifiable lvalue argument, corresponding to the fact that the desired effect of the function may include leaving a useful value in the argument variable. A caller with an rvalue expression that it wishes to pass to such a function would be forced to store it in a named variable to be able to make the call, since the language only provides implicit conversion to a constant lvalue reference (referring to a temporary) from an rvalue. (Unlike the opposite situation handled by std::move, a cast from Y&& to Y&, with Y the smart pointer type, is not possible; nonetheless this conversion could be obtained by a simple template function if really desired; see https://stackoverflow.com/a/24868376/1436796). For the case where the called function intends to unconditionally take ownership of the object, stealing from the argument, the obligation to provide an lvalue argument is giving the wrong signal: the variable will have no useful value after the call. Therefore mode 3, which gives identical possibilities inside our function but asks callers to provide an rvalue, should be preferred for such usage.

However there is a valid use case for mode 2, namely functions that may modify the pointer, or the object pointed to in a way that involves ownership. For instance, a function that prefixes a node to a list provides an example of such use:

void prepend (int x, list& l) { l = list( new node{ x, std::move(l)} ); }

Clearly it would be undesirable here to force callers to use std::move, since their smart pointer still owns a well defined and non-empty list after the call, though a different one than before.

Again it is interesting to observe what happens if the prepend call fails for lack of free memory. Then the new call will throw std::bad_alloc; at this point in time, since no node could be allocated, it is certain that the passed rvalue reference (mode 3) from std::move(l) cannot yet have been pilfered, as that would be done to construct the next field of the node that failed to be allocated. So the original smart pointer l still holds the original list when the error is thrown; that list will either be properly destroyed by the smart pointer destructor, or in case l should survive thanks to a sufficiently early catch clause, it will still hold the original list.

That was a constructive example; with a wink to this question one can also give the more destructive example of removing the first node containing a given value, if any:

void remove_first(int x, list& l)
{ list* p = &l;
  while ((*p).get()!=nullptr and (*p)->entry!=x)
    p = &(*p)->next;
  if ((*p).get()!=nullptr)
    (*p).reset((*p)->next.release()); // or equivalent: *p = std::move((*p)->next); 
}

Again the correctness is quite subtle here. Notably, in the final statement the pointer (*p)->next held inside the node to be removed is unlinked (by release, which returns the pointer but makes the original null) before reset (implicitly) destroys that node (when it destroys the old value held by p), ensuring that one and only one node is destroyed at that time. (In the alternative form mentioned in the comment, this timing would be left to the internals of the implementation of the move-assignment operator of the std::unique_ptr instance list; the standard says 20.7.1.2.3;2 that this operator should act "as if by calling reset(u.release())", whence the timing should be safe here too.)

Note that prepend and remove_first cannot be called by clients who store a local node variable for an always non-empty list, and rightly so since the implementations given could not work for such cases.

Mode 3: pass a smart pointer by (modifiable) rvalue reference

This is the preferred mode to use when simply taking ownership of the pointer. I would like to call this method call by check: caller must accept relinquishing ownership, as if providing cash, by signing the check, but the actual withdrawal is postponed until the called function actually pilfers the pointer (exactly as it would when using mode 2). The "signing of the check" concretely means callers have to wrap an argument in std::move (as in mode 1) if it is an lvalue (if it is an rvalue, the "giving up ownership" part is obvious and requires no separate code).

Note that technically mode 3 behaves exactly as mode 2, so the called function does not have to assume ownership; however I would insist that if there is any uncertainty about ownership transfer (in normal usage), mode 2 should be preferred to mode 3, so that using mode 3 is implicitly a signal to callers that they are giving up ownership. One might retort that only mode 1 argument passing really signals forced loss of ownership to callers. But if a client has any doubts about intentions of the called function, she is supposed to know the specifications of the function being called, which should remove any doubt.

It is surprisingly difficult to find a typical example involving our list type that uses mode 3 argument passing. Moving a list b to the end of another list a is a typical example; however a (which survives and holds the result of the operation) is better passed using mode 2:

void append (list& a, list&& b)
{ list* p=&a;
  while ((*p).get()!=nullptr) // find end of list a
    p=&(*p)->next;
  *p = std::move(b); // attach b; the variable b relinquishes ownership here
}

A pure example of mode 3 argument passing is the following that takes a list (and its ownership), and returns a list containing the identical nodes in reverse order.

list reversed (list&& l) noexcept // pilfering reversal of list
{ list p(l.release()); // move list into temporary for traversal
  list result(nullptr);
  while (p.get()!=nullptr)
  { // permute: result --> p->next --> p --> (cycle to result)
    result.swap(p->next);
    result.swap(p);
  }
  return result;
}

This function might be called as in l = reversed(std::move(l)); to reverse the list into itself, but the reversed list can also be used differently.

Here the argument is immediately moved to a local variable for efficiency (one could have used the parameter l directly in the place of p, but then accessing it each time would involve an extra level of indirection); hence the difference with mode 1 argument passing is minimal. In fact using that mode, the argument could have served directly as local variable, thus avoiding that initial move; this is just an instance of the general principle that if an argument passed by reference only serves to initialise a local variable, one might just as well pass it by value instead and use the parameter as local variable.

Using mode 3 appears to be advocated by the standard, as witnessed by the fact that all provided library functions that transfer ownership of smart pointers using mode 3. A particular convincing case in point is the constructor std::shared_ptr<T>(auto_ptr<T>&& p). That constructor used (in std::tr1) to take a modifiable lvalue reference (just like the auto_ptr<T>& copy constructor), and could therefore be called with an auto_ptr<T> lvalue p as in std::shared_ptr<T> q(p), after which p has been reset to null. Due to the change from mode 2 to 3 in argument passing, this old code must now be rewritten to std::shared_ptr<T> q(std::move(p)) and will then continue to work. I understand that the committee did not like the mode 2 here, but they had the option of changing to mode 1, by defining std::shared_ptr<T>(auto_ptr<T> p) instead, they could have ensured that old code works without modification, because (unlike unique-pointers) auto-pointers can be silently dereferenced to a value (the pointer object itself being reset to null in the process). Apparently the committee so much preferred advocating mode 3 over mode 1, that they chose to actively break existing code rather than to use mode 1 even for an already deprecated usage.

When to prefer mode 3 over mode 1

Mode 1 is perfectly usable in many cases, and might be preferred over mode 3 in cases where assuming ownership would otherwise takes the form of moving the smart pointer to a local variable as in the reversed example above. However, I can see two reasons to prefer mode 3 in the more general case:

• It is slightly more efficient to pass a reference than to create a temporary and nix the old pointer (handling cash is somewhat laborious); in some scenarios the pointer may be passed several times unchanged to another function before it is actually pilfered. Such passing will generally require writing std::move (unless mode 2 is used), but note that this is just a cast that does not actually do anything (in particular no dereferencing), so it has zero cost attached.

• Should it be conceivable that anything throws an exception between the start of the function call and the point where it (or some contained call) actually moves the pointed-to object into another data structure (and this exception is not already caught inside the function itself), then when using mode 1, the object referred to by the smart pointer will be destroyed before a catch clause can handle the exception (because the function parameter was destructed during stack unwinding), but not so when using mode 3. The latter gives the caller has the option to recover the data of the object in such cases (by catching the exception). Note that mode 1 here does not cause a memory leak, but may lead to an unrecoverable loss of data for the program, which might be undesirable as well.

Returning a smart pointer: always by value

To conclude a word about returning a smart pointer, presumably pointing to an object created for use by the caller. This is not really a case comparable with passing pointers into functions, but for completeness I would like to insist that in such cases always return by value (and don't use std::move in the return statement). Nobody wants to get a reference to a pointer that probably has just been nixed.

Dason K. and I have the pacman package that can do this nicely. The function p_load in the package does this. The first line is just to ensure that pacman is installed.

Actual Answer:

The default deserializer for enums uses .name() to deserialize, so it's not using the @JsonValue. So as @OldCurmudgeon pointed out, you'd need to pass in {"event": "FORGOT_PASSWORD"} to match the .name() value.

An other option (assuming you want the write and read json values to be the same)...

More Info:

There is (yet) another way to manage the serialization and deserialization process with Jackson. You can specify these annotations to use your own custom serializer and deserializer:

@JsonSerialize(using = MySerializer.class)
@JsonDeserialize(using = MyDeserializer.class)
public final class MyClass {
    ...
}

Then you have to write MySerializer and MyDeserializer which look like this:

MySerializer

public final class MySerializer extends JsonSerializer<MyClass>
{
    @Override
    public void serialize(final MyClass yourClassHere, final JsonGenerator gen, final SerializerProvider serializer) throws IOException, JsonProcessingException
    {
        // here you'd write data to the stream with gen.write...() methods
    }

}

MyDeserializer

public final class MyDeserializer extends org.codehaus.jackson.map.JsonDeserializer<MyClass>
{
    @Override
    public MyClass deserialize(final JsonParser parser, final DeserializationContext context) throws IOException, JsonProcessingException
    {
        // then you'd do something like parser.getInt() or whatever to pull data off the parser
        return null;
    }

}

Last little bit, particularly for doing this to an enum JsonEnum that serializes with the method getYourValue(), your serializer and deserializer might look like this:

public void serialize(final JsonEnum enumValue, final JsonGenerator gen, final SerializerProvider serializer) throws IOException, JsonProcessingException
{
    gen.writeString(enumValue.getYourValue());
}

public JsonEnum deserialize(final JsonParser parser, final DeserializationContext context) throws IOException, JsonProcessingException
{
    final String jsonValue = parser.getText();
    for (final JsonEnum enumValue : JsonEnum.values())
    {
        if (enumValue.getYourValue().equals(jsonValue))
        {
            return enumValue;
        }
    }
    return null;
}

I know this is a different twist on the answer, but isn't this more of a concern for a web server? For example, nginx, could help.

The ngx_http_headers_module module allows adding the “Expires” and “Cache-Control” header fields, and arbitrary fields, to a response header

...

location ~ ^<REGXP MATCHING CORS ROUTES> {
    add_header Access-Control-Allow-Methods POST
    ...
}
...

Adding nginx in front of your go service in production seems wise. It provides a lot more feature for authorizing, logging,and modifying requests. Also, it gives the ability to control who has access to your service and not only that but one can specify different behavior for specific locations in your app, as demonstrated above.

I could go on about why to use a web server with your go api, but I think that's a topic for another discussion.

To access the index in this case you access the name attribute:

In [182]:

df = pd.DataFrame([[1,2,3],[4,5,6]], columns=['a','b','c'])
def rowFunc(row):
    return row['a'] + row['b'] * row['c']

def rowIndex(row):
    return row.name
df['d'] = df.apply(rowFunc, axis=1)
df['rowIndex'] = df.apply(rowIndex, axis=1)
df
Out[182]:
   a  b  c   d  rowIndex
0  1  2  3   7         0
1  4  5  6  34         1

Note that if this is really what you are trying to do that the following works and is much faster:

In [198]:

df['d'] = df['a'] + df['b'] * df['c']
df
Out[198]:
   a  b  c   d
0  1  2  3   7
1  4  5  6  34

In [199]:

%timeit df['a'] + df['b'] * df['c']
%timeit df.apply(rowIndex, axis=1)
10000 loops, best of 3: 163 µs per loop
1000 loops, best of 3: 286 µs per loop

Looking at this question 3+ years later, you could just do:

In[15]:
df['d'],df['rowIndex'] = df['a'] + df['b'] * df['c'], df.index
df

Out[15]: 
   a  b  c   d  rowIndex
0  1  2  3   7         0
1  4  5  6  34         1

but assuming it isn't as trivial as this, whatever your rowFunc is really doing, you should look to use the vectorised functions, and then use them against the df index:

In[16]:
df['newCol'] = df['a'] + df['b'] + df['c'] + df.index
df

Out[16]: 
   a  b  c   d  rowIndex  newCol
0  1  2  3   7         0       6
1  4  5  6  34         1      16

You can do like this

var name = "foo";_x000D_
var value = "Hello foos";_x000D_
eval("var "+name+" = '"+value+"';");_x000D_
alert(foo);

Here's a simpler solution using what Akhil Sekharan has provided but with a little change.

var inputs = document.getElementsByTagName('input');

for (var i = 0; i < inputs.length; i += 1) {
if(parseInt(inputs[i].value)){
        inputs[i].value = '';
       }
    }????
document.getElementById('total').value = total;

I'd refrain from using floats for this sort of thing; I'd rather use inline-block.

Some more points to consider:

• Inline styles are bad for maintainability
• You shouldn't have spaces in selector names
• You missed some important HTML tags, like <head> and <body>
• You didn't include a doctype

Here's a better way to format your document:

<!DOCTYPE html>
<html>
<head>
<title>Website Title</title>
<style type="text/css">
* {margin: 0; padding: 0;}
#container {height: 100%; width:100%; font-size: 0;}
#left, #middle, #right {display: inline-block; *display: inline; zoom: 1; vertical-align: top; font-size: 12px;}
#left {width: 25%; background: blue;}
#middle {width: 50%; background: green;}
#right {width: 25%; background: yellow;}
</style>
</head>
<body>
<div id="container">
    <div id="left">Left Side Menu</div>
    <div id="middle">Random Content</div>
    <div id="right">Right Side Menu</div>
</div>
</body>
</html>

Here's a jsFiddle for good measure.

In this case it is just coding style.

Use of var is only necessary when dealing with anonymous types.
In other situations it's a matter of taste.

Use npm ls (there is even json output)

From the script:

test.js:

function npmls(cb) {
  require('child_process').exec('npm ls --json', function(err, stdout, stderr) {
    if (err) return cb(err)
    cb(null, JSON.parse(stdout));
  });
}
npmls(console.log);

run:

> node test.js
null { name: 'x11', version: '0.0.11' }

see if their duplicate jars or dependencies your adding remove it and your error will be gone: Eg: if you add android:supportv4 jar and also dependency you will get the error so remove the jar error will be gone

Here is my little contribution:

function inRange($number) {
  $ranges = [0, 13, 17, 24, 34, 44, 54, 65, 200];
  $n = count($ranges);

  while($n--){
    if( $number > $ranges[$n] )
      return $ranges[$n]+1 .'-'. $ranges[$n + 1];
  }

Neither way is necessarily correct or incorrect, they are just two different kinds of class elements:

• Elements outside the __init__ method are static elements; they belong to the class.
• Elements inside the __init__ method are elements of the object (self); they don't belong to the class.

You'll see it more clearly with some code:

class MyClass:
    static_elem = 123

    def __init__(self):
        self.object_elem = 456

c1 = MyClass()
c2 = MyClass()

# Initial values of both elements
>>> print c1.static_elem, c1.object_elem 
123 456
>>> print c2.static_elem, c2.object_elem
123 456

# Nothing new so far ...

# Let's try changing the static element
MyClass.static_elem = 999

>>> print c1.static_elem, c1.object_elem
999 456
>>> print c2.static_elem, c2.object_elem
999 456

# Now, let's try changing the object element
c1.object_elem = 888

>>> print c1.static_elem, c1.object_elem
999 888
>>> print c2.static_elem, c2.object_elem
999 456

As you can see, when we changed the class element, it changed for both objects. But, when we changed the object element, the other object remained unchanged.

document.getElementById('id_iframe').contentWindow.document.write('content');

I'd thoroughly recommend reading the articles Enough With The Rainbow Tables: What You Need To Know About Secure Password Schemes [dead link, copy at the Internet Archive] and How To Safely Store A Password.

Lots of coders, myself included, think they understand security and hashing. Sadly most of us just don't.

Change build target from 1.5 or 1.6 to 2.2 (API version 8), and check if you have the % character in string.xml. If yes, replace with %%.

The underscore is put there by the compiler and used by the linker. The basic path is:

main.c
test.h ---> [compiler] ---> main.o --+
                                     |
test.c ---> [compiler] ---> test.o --+--> [linker] ---> main.exe

So, your main program should include the header file for the test module which should consist only of declarations, such as the function prototype:

void test(void);

This lets the compiler know that it exists when main.c is being compiled but the actual code is in test.c, then test.o.

It's the linking phase that joins together the two modules.

By including test.c into main.c, you're defining the test() function in main.o. Presumably, you're then linking main.o and test.o, both of which contain the function test().

You can be used this step is very useful:

for i in `ls -l folder1 | grep -v total | awk '{print $ ( ? )}'`
do
   cd folder1
   cp $i folder2/$i.`date +%m%d%Y`
done

String Interpolation

is a concept that languages like Perl have had for quite a while, and now we’ll get this ability in C# as well. In String Interpolation, we simply prefix the string with a $ (much like we use the @ for verbatim strings). Then, we simply surround the expressions we want to interpolate with curly braces (i.e. { and }):

It looks a lot like the String.Format() placeholders, but instead of an index, it is the expression itself inside the curly braces. In fact, it shouldn’t be a surprise that it looks like String.Format() because that’s really all it is – syntactical sugar that the compiler treats like String.Format() behind the scenes.

A great part is, the compiler now maintains the placeholders for you so you don’t have to worry about indexing the right argument because you simply place it right there in the string.

C# string interpolation is a method of concatenating,formatting and manipulating strings. This feature was introduced in C# 6.0. Using string interpolation, we can use objects and expressions as a part of the string interpolation operation.

Syntax of string interpolation starts with a ‘$’ symbol and expressions are defined within a bracket {} using the following syntax.

{<interpolatedExpression>[,<alignment>][:<formatString>]}  

Where:

• interpolatedExpression - The expression that produces a result to be formatted
• alignment - The constant expression whose value defines the minimum number of characters in the string representation of the result of the interpolated expression. If positive, the string representation is right-aligned; if negative, it's left-aligned.
• formatString - A format string that is supported by the type of the expression result.

The following code example concatenates a string where an object, author as a part of the string interpolation.

string author = "Mohit";  
string hello = $"Hello {author} !";  
Console.WriteLine(hello);  // Hello Mohit !

There is an easier solution to this problem.

You just need to add a t to the mode so it becomes wt. This causes Python to open the file as a text file and not binary. Then everything will just work.

The complete program becomes this:

plaintext = input("Please enter the text you want to compress")
filename = input("Please enter the desired filename")
with gzip.open(filename + ".gz", "wt") as outfile:
    outfile.write(plaintext)

As cartman pointed out, you can use any kind of hash value for finding exact duplicates.

One starting point for finding close images could be here. This is a tool used by CG companies to check if revamped images are still showing essentially the same scene.

Taking the knowledge from all the previous answers combined,

this is what I came up with as a solution:

function toFixedWithoutRounding(num, fractionDigits) {
  if ((num > 0 && num < 0.000001) || (num < 0 && num > -0.000001)) {
    // HACK: below this js starts to turn numbers into exponential form like 1e-7.
    // This gives wrong results so we are just changing the original number to 0 here
    // as we don't need such small numbers anyway.
    num = 0;
  }
  const re = new RegExp('^-?\\d+(?:\.\\d{0,' + (fractionDigits || -1) + '})?');
  return Number(num.toString().match(re)[0]).toFixed(fractionDigits);
}

VSCode comes with in-built color themes which can be used to change the colors of the editor and the terminal.

• For changing the color theme press ctrl+k+t in windows/ubuntu or cmd+k+t on mac.
• Alternatively you can open command palette by pressing ctrl+shift+p in windows/ubuntu or cmd+shift+p on mac and type color. Select preferences: color theme from the options, to select your favourite color.
• You can also install more themes from the extensions menu on the left bar. just search category:themes to install your favourite themes. (If you need to sort the themes by installs search category:themes @sort:installs)

Edit - for manually editing colors in terminal

VSCode team have removed customizing colors from user settings page. Currently using the themes is the only way to customize terminal colors in VSCode. For more information check out issue #6766

target isn't valid on an input element.

In this case, though, your redirection is done by Javascript, so you could have your script open up a new window.

You may use @JsonIgnore to break the cycle (reference).

You need to import org.codehaus.jackson.annotate.JsonIgnore (legacy versions) or com.fasterxml.jackson.annotation.JsonIgnore (current versions).

if you are using jquery 1.7

$('html').off('click');

else

$('html').unbind('click');

You should be able to use join, which joins on the index as default. Given your desired result, you must use outer as the join type.

>>> df1.join(df2, how='outer')
            V1  V2
A 1/1/2012  12  15
  2/1/2012  14 NaN
  3/1/2012 NaN  21
B 1/1/2012  15  24
  2/1/2012   8   9
C 1/1/2012  17 NaN
  2/1/2012   9 NaN
D 1/1/2012 NaN   7
  2/1/2012 NaN  16

Signature: _.join(other, on=None, how='left', lsuffix='', rsuffix='', sort=False) Docstring: Join columns with other DataFrame either on index or on a key column. Efficiently Join multiple DataFrame objects by index at once by passing a list.

One problem is that easy_install is set up to download and install .egg files or source distributions (contained within .tgz, .tar, .tar.gz, .tar.bz2, or .zip files). It doesn't know how to deal with the PyWin32 extensions because they are put within a separate installer executable. You will need to download the appropriate PyWin32 installer file (for Python 2.7) and run it yourself. When you run easy_install again (provided you have it installed right, like in Sergio's instructions), you should see that your winpexpect package has been installed correctly.

Since it's Windows and open source we are talking about, it can often be a messy combination of install methods to get things working properly. However, easy_install is still better than hand-editing configuration files, for sure.

Since I found this question not being aware, that mysql always stores time in timestamp fields in UTC but will display (e.g. phpmyadmin) in local time zone I would like to add my findings.

I have an automatically updated last_modified field, defined as:

`last_modified` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP

Looking at it with phpmyadmin, it looks like it is in local time, internally it is UTC

SET time_zone = '+04:00'; // or '+00:00' to display dates in UTC or 'UTC' if time zones are installed.
SELECT last_modified, UNIX_TIMESTAMP(last_modified), from_unixtime(UNIX_TIMESTAMP(last_modified), '%Y-%c-%d %H:%i:%s'), CONVERT_TZ(last_modified,@@session.time_zone,'+00:00') as UTC FROM `table_name`

In any constellation, UNIX_TIMESTAMP and 'as UTC' are always displayed in UTC time.

Run this twice, first without setting the time_zone.

Maybe this will help

awk '$3 ~ /snow|snowman/' dummy_file

Try this (update, not after update)

CREATE TRIGGER [dbo].[xxx_update] ON [dbo].[MYTABLE]
    FOR UPDATE
    AS
    BEGIN

        UPDATE MYTABLE
        SET mytable.CHANGED_ON = GETDATE()
            ,CHANGED_BY = USER_NAME(USER_ID())
        FROM inserted
        WHERE MYTABLE.ID = inserted.ID

    END

Try this:

UPDATE test
SET
   field = 1
WHERE id = 123 and condition

Another addition: be careful when replacing multiples and converting the type of the column back from object to float. If you want to be certain that your None's won't flip back to np.NaN's apply @andy-hayden's suggestion with using pd.where. Illustration of how replace can still go 'wrong':

In [1]: import pandas as pd

In [2]: import numpy as np

In [3]: df = pd.DataFrame({"a": [1, np.NAN, np.inf]})

In [4]: df
Out[4]:
     a
0  1.0
1  NaN
2  inf

In [5]: df.replace({np.NAN: None})
Out[5]:
      a
0     1
1  None
2   inf

In [6]: df.replace({np.NAN: None, np.inf: None})
Out[6]:
     a
0  1.0
1  NaN
2  NaN

In [7]: df.where((pd.notnull(df)), None).replace({np.inf: None})
Out[7]:
     a
0  1.0
1  NaN
2  NaN

yes, %c will print a single char:

printf("%c", 'h');

also, putchar/putc will work too. From "man putchar":

#include <stdio.h>

int fputc(int c, FILE *stream);
int putc(int c, FILE *stream);
int putchar(int c);

* fputc() writes the character c, cast to an unsigned char, to stream.
* putc() is equivalent to fputc() except that it may be implemented as a macro which evaluates stream more than once.
* putchar(c); is equivalent to putc(c,stdout).

EDIT:

Also note, that if you have a string, to output a single char, you need get the character in the string that you want to output. For example:

const char *h = "hello world";
printf("%c\n", h[4]); /* outputs an 'o' character */

At first, I also preferred to pass Optionals as parameter, but if you switch from an API-Designer perspective to a API-User perspective, you see the disadvantages.

For your example, where each parameter is optional, I would suggest to change the calculation method into an own class like follows:

Optional<String> p1 = otherObject.getP1();
Optional<BigInteger> p2 = otherObject.getP2();

MyCalculator mc = new MyCalculator();
p1.map(mc::setP1);
p2.map(mc::setP2);
int result = mc.calculate();

Suppose I have an SVG which looks like this:

And I want to put it in a div and make it fill the div responsively. My way of doing it is as follows:

First I open the SVG file in an application like inkscape. In File->Document Properties I set the width of the document to 800px and and the height to 600px (you can choose other sizes). Then I fit the SVG into this document.

Then I save this file as a new SVG file and get the path data from this file. Now in HTML the code that does the magic is as follows:

<div id="containerId">    
    <svg
    id="svgId" 
    xmlns:svg="http://www.w3.org/2000/svg"
    xmlns="http://www.w3.org/2000/svg"
    version="1.1"
    x="0"
    y="0"
    width="100%"
    height="100%"
    viewBox="0 0 800 600"
    preserveAspectRatio="none">
       <path d="m0 0v600h800v-600h-75.07031l-431 597.9707-292.445315-223.99609 269.548825-373.97461h-271.0332z" fill="#f00"/>
    </svg>
</div>

Note that width and height of SVG are both set to 100%, since we want it to fill the container vertically and horizontally ,but width and height of the viewBox are the same as the width and height of the document in inkscape which is 800px X 600px. The next thing you need to do is set the preserveAspectRatio to "none". If you need to have more information on this attribute here's a good link. And that's all there is to it.

One more thing is that this code works on almost all the major browsers even the old ones but on some versions of android and ios you need to use some javascrip/jQuery code to keep it consistent. I use the following in document ready and resize functions:

$('#svgId').css({
    'width': $('#containerId').width() + 'px',
    'height': $('#containerId').height() + 'px'
});

Hope it helps!

Oldest:

oldest = min(datetimes)

Youngest before now:

now = datetime.datetime.now(pytz.utc)
youngest = max(dt for dt in datetimes if dt < now)

1 gotcha: when you use "p" to put the line, it puts it after the line your cursor is on, so if you want to add the line after the line you're yanking, don't move the cursor down a line before putting the new line.

Add Regular to syntax and use gfn:

set gfn= Monospace\ Regular:h13

string result = DateTime.Now.Date.AddDays(-1).ToString("yyyy-MM-dd");

You also need add these lines in PostgreSQL and restart the server:

log_directory = 'pg_log'                    
log_filename = 'postgresql-dateformat.log'
log_statement = 'all'
logging_collector = on

Just to add something to @Habib's answer, you can also check if given JSON is from a valid type:

public static bool IsValidJson<T>(this string strInput)
{
    if(string.IsNullOrWhiteSpace(strInput)) return false;

    strInput = strInput.Trim();
    if ((strInput.StartsWith("{") && strInput.EndsWith("}")) || //For object
        (strInput.StartsWith("[") && strInput.EndsWith("]"))) //For array
    {
        try
        {
            var obj = JsonConvert.DeserializeObject<T>(strInput);
            return true;
        }
        catch // not valid
        {             
            return false;
        }
    }
    else
    {
        return false;
    }
}

I just timed some functions out of curiosity. In these tests I'm removing non-alphanumeric characters from the string string.printable (part of the built-in string module). The use of compiled '[\W_]+' and pattern.sub('', str) was found to be fastest.

Use these

export class TableColumns<T> {
   constructor(private t: new () => T) {
        var fields: string[] = Object.keys(new t())

        console.log('fields', fields)
        console.log('t', t)

    }
}

Usage

columns_logs = new TableColumns<LogItem>(LogItem);

OK guys I finally overcame this problem. Here is the solution:

1. Download gradle-1.6-bin.zip for offline use.

2. Paste it in the C:\Users\username\.gradle directory.

3. Open Android Studio and click on the "Create New Project" option and you will not get this error any more while offline.

   You might get some other errors like this:

   

   Don't worry, just ignore it. Your project has been created.

4. So now click on "Import Project" and go to the path C:\Users\username\AndroidStudioProjects and open your project and you are done.

1 - right click the highlight whose color you want to change

2 - select "Properties" in the popup menu

3 - choose the new color (as coobird suggested)

This solution is easy because you dont have to search for the highlight by its name ("Ocurrence" or "Write Ocurrence" etc), just right click and the appropriate window is shown.

There is also a convenient shortcut to get all elements of the array starting with specified index. For example "${A[@]:1}" would be the "tail" of the array, that is the array without its first element.

version=4.7.1
A=( ${version//\./ } )
echo "${A[@]}"    # 4 7 1
B=( "${A[@]:1}" )
echo "${B[@]}"    # 7 1

If you are serializing your data object, it will not be a proper json object. Take what you have, and just wrap the data object in a JSON.stringify().

$http({
    url: '/user_to_itsr',
    method: "POST",
    data: JSON.stringify({application:app, from:d1, to:d2}),
    headers: {'Content-Type': 'application/json'}
}).success(function (data, status, headers, config) {
    $scope.users = data.users; // assign  $scope.persons here as promise is resolved here 
}).error(function (data, status, headers, config) {
    $scope.status = status + ' ' + headers;
});

You have to move the portion of the background task that updates the UI onto the main thread. There is a simple piece of code for this:

runOnUiThread(new Runnable() {

    @Override
    public void run() {

        // Stuff that updates the UI

    }
});

Documentation for Activity.runOnUiThread.

Just nest this inside the method that is running in the background, and then copy paste the code that implements any updates in the middle of the block. Include only the smallest amount of code possible, otherwise you start to defeat the purpose of the background thread.

You need to receive the POST data in chunks using request.on('data', function(chunk) {...})

const http = require('http');

http.createServer((req, res) => {
    if (req.method == 'POST') {
        whole = ''
        req.on('data', (chunk) => {
            # consider adding size limit here
            whole += chunk.toString()
        })

        req.on('end', () => {
            console.log(whole)
            res.writeHead(200, 'OK', {'Content-Type': 'text/html'})
            res.end('Data received.')
        })
    }
}).listen(8080)

You should consider adding a size limit at the indicated position as thejh suggested.

JFilter http://code.google.com/p/jfilter/ suites your requirement.

JFilter is a simple and high performance open source library to query collection of Java beans.

Key features

• Support of collection (java.util.Collection, java.util.Map and Array) properties.
• Support of collection inside collection of any depth.
• Support of inner queries.
• Support of parameterized queries.
• Can filter 1 million records in few 100 ms.
• Filter ( query) is given in simple json format, it is like Mangodb queries. Following are some examples.
  • { "id":{"$le":"10"}
    • where object id property is less than equals to 10.
  • { "id": {"$in":["0", "100"]}}
    • where object id property is 0 or 100.
  • {"lineItems":{"lineAmount":"1"}}
    • where lineItems collection property of parameterized type has lineAmount equals to 1.
  • { "$and":[{"id": "0"}, {"billingAddress":{"city":"DEL"}}]}
    • where id property is 0 and billingAddress.city property is DEL.
  • {"lineItems":{"taxes":{ "key":{"code":"GST"}, "value":{"$gt": "1.01"}}}}
    • where lineItems collection property of parameterized type which has taxes map type property of parameteriszed type has code equals to GST value greater than 1.01.
  • {'$or':[{'code':'10'},{'skus': {'$and':[{'price':{'$in':['20', '40']}}, {'code':'RedApple'}]}}]}
    • Select all products where product code is 10 or sku price in 20 and 40 and sku code is "RedApple".

Use the function Contains from the strings package.

import (
    "strings"
)
strings.Contains("something", "some") // true

The Image pull policy will always actually help to pull the image every single time a new pod is created (this can be in any case like scaling the replicas, or pod dies and new pod is created)

But if you want to update the image of the current running pod, deployment is the best way. It leaves you flawless update without any problem (mainly when you have a persistent volume attached to the pod) :)

The answer to the question was already posted by the @latemail in the comments above. You can use regular expressions for the second and subsequent arguments of filter like this:

dplyr::filter(df, !grepl("RTB",TrackingPixel))

Since you have not provided the original data, I will add a toy example using the mtcars data set. Imagine you are only interested in cars produced by Mazda or Toyota.

mtcars$type <- rownames(mtcars)
dplyr::filter(mtcars, grepl('Toyota|Mazda', type))

   mpg cyl  disp  hp drat    wt  qsec vs am gear carb           type
1 21.0   6 160.0 110 3.90 2.620 16.46  0  1    4    4      Mazda RX4
2 21.0   6 160.0 110 3.90 2.875 17.02  0  1    4    4  Mazda RX4 Wag
3 33.9   4  71.1  65 4.22 1.835 19.90  1  1    4    1 Toyota Corolla
4 21.5   4 120.1  97 3.70 2.465 20.01  1  0    3    1  Toyota Corona

If you would like to do it the other way round, namely excluding Toyota and Mazda cars, the filter command looks like this:

dplyr::filter(mtcars, !grepl('Toyota|Mazda', type))

I encountered the same problem:

E/AndroidRuntime: FATAL EXCEPTION: Thread-4

Before: onCreate function

Thread thread = new Thread(new Runnable() {
    @Override
    public void run() {
        Toast.makeText(getBaseContext(), "Thread", Toast.LENGTH_LONG).show();
    }
});
thread.start();

After: onCreate function

runOnUiThread(new Runnable() {
    @Override
    public void run() {
        Toast.makeText(getBaseContext(), "Thread", Toast.LENGTH_LONG).show();
    }
});

it worked.

Url Encoding is easy in .NET. Use:

System.Web.HttpUtility.UrlEncode(string url)

If that'll be decoded to get the folder name, you'll still need to exclude characters that can't be used in folder names (*, ?, /, etc.)

Assuming Nothing Follows Them

If these two div elements are basically your main layout elements, and nothing follows them in the html, then there is a pure HMTL/CSS solution that takes the normal order shown in this fiddle and is able to flip it vertically as shown in this fiddle using one additional wrapper div like so:

HTML

<div class="wrapper flipit">
   <div id="first_div">first div</div>
   <div id="second_div">second div</div>
</div>

CSS

.flipit {
    position: relative;
}
.flipit #first_div {
    position: absolute;
    top: 100%;
    width: 100%;
}

This would not work if elements follow these div's, as this fiddle illustrates the issue if the following elements are not wrapped (they get overlapped by #first_div), and this fiddle illustrates the issue if the following elements are also wrapped (the #first_div changes position with both the #second_div and the following elements). So that is why, depending on your use case, this method may or may not work.

For an overall layout scheme, where all other elements exist inside the two div's, it can work. For other scenarios, it will not.

You need to put the full path in the php ini when loading the mysql dll, i.e :-

extension=c:/php54/ext/php_mbstring.dll
extension=c:/php54/ext/php_mysql.dll

Then you don't need to move them to the windows folder.

It can be done using a single line:

perl -pi.back -e 's/oldString/newString/g;' inputFileName

Pay attention that oldString is processed as a Regular Expression.
In case the string contains any of {}[]()^$.|*+? (The special characters for Regular Expression syntax) make sure to escape them unless you want it to be processed as a regular expression.
Escaping it is done by \, so \[.

You only need to float the div element to the right and give it a margin. Make sure dont use "absolute" for this case.

#date {
  margin-right:5px;
  position:relative;
  float:right;
}

Create a file ~/.curlrc with the following content

cacert=/etc/ssl/certs/ca-certificates.crt

as follows

echo "cacert=/etc/ssl/certs/ca-certificates.crt" >> ~/.curlrc

We did it like this:

from p in Products                         
join bp in BaseProducts on p.BaseProductId equals bp.Id                    
where !string.IsNullOrEmpty(p.SomeId) && p.LastPublished >= lastDate                         
group new { p, bp } by new { p.SomeId } into pg    
let firstproductgroup = pg.FirstOrDefault()
let product = firstproductgroup.p
let baseproduct = firstproductgroup.bp
let minprice = pg.Min(m => m.p.Price)
let maxprice = pg.Max(m => m.p.Price)
select new ProductPriceMinMax
{
SomeId = product.SomeId,
BaseProductName = baseproduct.Name,
CountryCode = product.CountryCode,
MinPrice = minprice, 
MaxPrice = maxprice
};

EDIT: we used the version of AakashM, because it has better performance

If the line before your error contains COMMENT '' either populate the comment in the script or remove the empty comment definition. I've found this in scripts generated by MySQL Workbench.

Here is a list of special characters that you can escape when creating a string literal for JSON:

\b  Backspace (ASCII code 08)
\f  Form feed (ASCII code 0C)
\n  New line
\r  Carriage return
\t  Tab
\v  Vertical tab
\'  Apostrophe or single quote
\"  Double quote
\\  Backslash character

Reference: String literals

Some of these are more optional than others. For instance, your string should be perfectly valid whether you escape the tab character or leave in a tab literal. You should certainly be handling the backslash and quote characters, though.

This is a simple method to export the database to a folder named backup folder you can name it as you want and a simple method to import the database from the same folder a

You can use COM, or P/Invoke from .Net, to open the Winspool.drv driver and send bytes directly to devices. But you don't want to do that; this typically works only for the one device on the one version of the one driver you test with, and breaks on everything else. Take this from long, painful, personal experience.

What you want to do is get a barcode font or library that draws barcodes using plain old GDI or GDI+ commands; there's one for .Net here. This works on all devices, even after Zebra changes the driver.

For updating a record:

 UPDATE Employees SET [Photo] = (SELECT
 MyImage.* from Openrowset(Bulk
 'C:\photo.bmp', Single_Blob) MyImage)
 where Id = 10

Notes:

• Make sure to add the 'BULKADMIN' Role Permissions for the login you are using.
• Paths are not pointing to your computer when using SQL Server Management Studio. If you start SSMS on your local machine and connect to a SQL Server instance on server X, the file C:\photo.bmp will point to hard drive C: on server X, not your machine!

On most UNIX-like systems, you can also run:

expand -t4 oldfilename.py > newfilename.py

from the command line, changing the number if you want to replace tabs with a number of spaces other than 4. You can easily write a shell script to do this with a bunch of files at once, retaining the original file names.

Python 3.3.1 [MSC v.1600 32 bit (Intel)] on win32 14.May.2013

This worked for me, by following the code above

from tkinter import *
from PIL import ImageTk, Image
import os

root = Tk()
img = ImageTk.PhotoImage(Image.open("True1.gif"))
panel = Label(root, image = img)
panel.pack(side = "bottom", fill = "both", expand = "yes")
root.mainloop()

The main function must be declared as a non-member function in the global namespace. This means that it cannot be a static or non-static member function of a class, nor can it be placed in a namespace (even the unnamed namespace).

The name main is not reserved in C++ except as a function in the global namespace. You are free to declare other entities named main, including among other things, classes, variables, enumerations, member functions, and non-member functions not in the global namespace.

You can declare a function named main as a member function or in a namespace, but such a function would not be the main function that designates where the program starts.

The main function cannot be declared as static or inline. It also cannot be overloaded; there can be only one function named main in the global namespace.

The main function cannot be used in your program: you are not allowed to call the main function from anywhere in your code, nor are you allowed to take its address.

The return type of main must be int. No other return type is allowed (this rule is in bold because it is very common to see incorrect programs that declare main with a return type of void; this is probably the most frequently violated rule concerning the main function).

There are two declarations of main that must be allowed:

int main()               // (1)
int main(int, char*[])   // (2)

In (1), there are no parameters.

In (2), there are two parameters and they are conventionally named argc and argv, respectively. argv is a pointer to an array of C strings representing the arguments to the program. argc is the number of arguments in the argv array.

Usually, argv[0] contains the name of the program, but this is not always the case. argv[argc] is guaranteed to be a null pointer.

Note that since an array type argument (like char*[]) is really just a pointer type argument in disguise, the following two are both valid ways to write (2) and they both mean exactly the same thing:

int main(int argc, char* argv[])
int main(int argc, char** argv)

Some implementations may allow other types and numbers of parameters; you'd have to check the documentation of your implementation to see what it supports.

main() is expected to return zero to indicate success and non-zero to indicate failure. You are not required to explicitly write a return statement in main(): if you let main() return without an explicit return statement, it's the same as if you had written return 0;. The following two main() functions have the same behavior:

int main() { }
int main() { return 0; }

There are two macros, EXIT_SUCCESS and EXIT_FAILURE, defined in <cstdlib> that can also be returned from main() to indicate success and failure, respectively.

The value returned by main() is passed to the exit() function, which terminates the program.

Note that all of this applies only when compiling for a hosted environment (informally, an environment where you have a full standard library and there's an OS running your program). It is also possible to compile a C++ program for a freestanding environment (for example, some types of embedded systems), in which case startup and termination are wholly implementation-defined and a main() function may not even be required. If you're writing C++ for a modern desktop OS, though, you're compiling for a hosted environment.

Keep the Screen On

First way:

getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

Second way:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:keepScreenOn="true">
    ...
</RelativeLayout>

Keep the CPU On:

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

and

PowerManager powerManager = (PowerManager) getSystemService(POWER_SERVICE);
WakeLock wakeLock = powerManager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "MyWakelockTag");
wakeLock.acquire();

To release the wake lock, call wakelock.release(). This releases your claim to the CPU. It's important to release a wake lock as soon as your app is finished using it to avoid draining the battery.

Docs here.

Online index rebuilds are less intrusive when it comes to locking tables. Offline rebuilds cause heavy locking of tables which can cause significant blocking issues for things that are trying to access the database while the rebuild takes place.

"Table locks are applied for the duration of the index operation [during an offline rebuild]. An offline index operation that creates, rebuilds, or drops a clustered, spatial, or XML index, or rebuilds or drops a nonclustered index, acquires a Schema modification (Sch-M) lock on the table. This prevents all user access to the underlying table for the duration of the operation. An offline index operation that creates a nonclustered index acquires a Shared (S) lock on the table. This prevents updates to the underlying table but allows read operations, such as SELECT statements."

http://msdn.microsoft.com/en-us/library/ms188388(v=sql.110).aspx

Additionally online index rebuilds are a enterprise (or developer) version only feature.

You can use a class that works much like a builder to contain your optional values like this.

public class Options {
    private String someString = "default value";
    private int someInt= 0;
    public Options setSomeString(String someString) {
        this.someString = someString;
        return this;
    }
    public Options setSomeInt(int someInt) {
        this.someInt = someInt;
        return this;
    }
}

public static void foo(Consumer<Options> consumer) {
    Options options = new Options();
    consumer.accept(options);
    System.out.println("someString = " + options.someString + ", someInt = " + options.someInt);
}

Use like

foo(o -> o.setSomeString("something").setSomeInt(5));

Output is

someString = something, someInt = 5

To skip all the optional values you'd have to call it like foo(o -> {}); or if you prefer, you can create a second foo() method that doesn't take the optional parameters.

Using this approach, you can specify optional values in any order without any ambiguity. You can also have parameters of different classes unlike with varargs. This approach would be even better if you can use annotations and code generation to create the Options class.

You can define a class constant in php. But your class constant would be accessible from any object instance as well. This is php's functionality. However, as of php7.1, you can define your class constants with access modifiers (public, private or protected).

A work around would be to define your constant as private or protected and then make them readable via a static function. This function should only return the constant values if called from the static context.

You can also create this static function in your parent class and simply inherit this parent class on all other classes to make it a default functionality.

You can use contains (this works with an arbitrary sequence):

df.filter($"foo".contains("bar"))

like (SQL like with SQL simple regular expression whith _ matching an arbitrary character and % matching an arbitrary sequence):

df.filter($"foo".like("bar"))

or rlike (like with Java regular expressions):

df.filter($"foo".rlike("bar"))

depending on your requirements. LIKE and RLIKE should work with SQL expressions as well.

SQL Server 2012 and up support LAG / LEAD functions to access the previous or subsequent row. SQL Server 2005 does not support this (in SQL2005 you need a join or something else).

A SQL 2012 example on this data

/* Prepare */
select * into #tmp
from
(
    select 2  as rowint,      23 as Value
    union select 3,       45
    union select 17,      10
    union select 9,       0
) x


/* The SQL 2012 query */
select rowInt, Value, LEAD(value) over (order by rowInt) - Value  
from #tmp

LEAD(value) will return the value of the next row in respect to the given order in "over" clause.

Either use:

pip install xlrd

And if you are using conda, use

conda install -c anaconda xlrd

That's it. good luck.

I'll throw this out there and then duck. The usual reason to check if a file exists is to avoid an error when attempting to open it. How about using the error handler to deal with that:

Function openFileTest(filePathName As String, ByRef wkBook As Workbook, _
                      errorHandlingMethod As Long) As Boolean
'Returns True if filePathName is successfully opened,

   Dim errorNum As Long

'***************************************************************************

   On Error Resume Next:
   Set wkBook = Workbooks.Open(fileName:=filePathName)
   If Err.Number <> 0 Then
      errorNum = Err.Number
      'Error while attempting to open the file. Maybe it doesn't exist?
      If Err.Number = 1004 Then
'***************************************************************************
      'File doesn't exist.
         'Better clear the error and point to the error handler before moving on.
         Err.Clear

         Err.Raise errorNum
      Else
         'No idea what the error is, but it's not due to a non-existant file
         'Invoke the error handler.
         Err.Clear
         On Error GoTo OPENFILETEST_FAIL:
         Err.Raise errorNum
      End If
   End If

   'Either the file was successfully opened or the problem was resolved.
   openFileTest = True
   Exit Function

OPENFILETEST_FAIL:
   errorNum = Err.Number

   'some other error. Not sure what this would be, so...
   If errorHandlingMethod < 2 Then
      'The easy out is to clear the error, reset to the default error handler,
      'and raise the error number again.

Simple answer:A grammar is said to be an LL(1),if the associated LL(1) parsing table has atmost one production in each table entry.

Take the simple grammar A -->Aa|b.[A is non-terminal & a,b are terminals]
   then find the First and follow sets A.
    First{A}={b}.
    Follow{A}={$,a}.

    Parsing table for Our grammar.Terminals as columns and Nonterminal S as a row element.

        a            b                   $
    --------------------------------------------
 S  |               A-->a                      |
    |               A-->Aa.                    |
    -------------------------------------------- 

As [S,b] contains two Productions there is a confusion as to which rule to choose.So it is not LL(1).

Some simple checks to see whether a grammar is LL(1) or not. Check 1: The Grammar should not be left Recursive. Example: E --> E+T. is not LL(1) because it is Left recursive. Check 2: The Grammar should be Left Factored.

Left factoring is required when two or more grammar rule choices share a common prefix string. Example: S-->A+int|A.

Check 3:The Grammar should not be ambiguous.

These are some simple checks.

According to nginx documentation

there is no syntax for NOT matching a regular expression. Instead, match the target regular expression and assign an empty block, then use location / to match anything else

So you could define something like

location ~ (dir1|file2\.php) { 
    # empty
}

location / {
    rewrite ^/(.*) http://example.com/$1 permanent; 
}

use ob_start(); before session_start(); at top of your page like this

<?php
ob_start();
session_start();

Even better, use DEFAULT instead of NULL. You want to store the default value, not a NULL that might trigger a default value.

But you'd better name all columns, with a piece of SQL you can create all the INSERT, UPDATE and DELETE's you need. Just check the information_schema and construct the queries you need. There is no need to do it all by hand, SQL can help you out.

Just escape your tag closures or use ascii code

ie

<\/script>

ie

<&#47;script>

Check out http://www.odata.org/

It defines the MERGE method, so in your case it would be something like this:

MERGE /customer/123

<customer>
   <status>DISABLED</status>
</customer>

Only the status property is updated and the other values are preserved.

The most basic way you can do this in SelectedIndexChanged events of DropDownLists. Check this code..

    <asp:DropDownList ID="DropDownList1" runat="server" onselectedindexchanged="DropDownList1_SelectedIndexChanged" Width="224px"
        AutoPostBack="True" AppendDataBoundItems="true">
    <asp:DropDownList ID="DropDownList2" runat="server"
        onselectedindexchanged="DropDownList2_SelectedIndexChanged">
    </asp:DropDownList> 


protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
    //Load DropDownList2

}
protected void DropDownList2_SelectedIndexChanged(object sender, EventArgs e)
{
    //Load DropDownList3
}

In Chrome, click the 3 dots and click More tools and click developer. On the console, type console.dir(yourObject).Click this link to view an example image

Or get the number of unique values for each column:

df.nunique()

dID    3
hID    5
mID    3
uID    5
dtype: int64

New in pandas 0.20.0 pd.DataFrame.agg

df.agg(['count', 'size', 'nunique'])

         dID  hID  mID  uID
count      8    8    8    8
size       8    8    8    8
nunique    3    5    3    5

You've always been able to do an agg within a groupby. I used stack at the end because I like the presentation better.

df.groupby('mID').agg(['count', 'size', 'nunique']).stack()


             dID  hID  uID
mID                       
A   count      5    5    5
    size       5    5    5
    nunique    3    5    5
B   count      2    2    2
    size       2    2    2
    nunique    2    2    2
C   count      1    1    1
    size       1    1    1
    nunique    1    1    1

I believe you can accomplish it by just having single ng-view. In the main template you can have ng-include sections for sub views, then in the main controller define model properties for each sub template. So that they will bind automatically to ng-include sections. This is same as having multiple ng-view

You can check the example given in ng-include documentation

in the example when you change the template from dropdown list it changes the content. Here assume you have one main ng-view and instead of manually selecting sub content by selecting drop down, you do it as when main view is loaded.

Use [ngClass] and conditionally apply class based on the id.

In your HTML file:

<li>
    <img [ngClass]="{'this-is-a-class': id === 1 }" id="1"  
         src="../../assets/images/1.jpg" (click)="addClass(id=1)"/>
</li>
<li>
    <img [ngClass]="{'this-is-a-class': id === 2 }" id="2"  
         src="../../assets/images/2.png" (click)="addClass(id=2)"/>
</li>

In your TypeScript file:

addClass(id: any) {
    this.id = id;
}

It doesn't inherit from Element because not all event targets are elements.

From MDN:

Element, document, and window are the most common event targets, but other objects can be event targets too, for example XMLHttpRequest, AudioNode, AudioContext, and others.

Even the KeyboardEvent you're trying to use can occur on a DOM element or on the window object (and theoretically on other things), so right there it wouldn't make sense for evt.target to be defined as an Element.

If it is an event on a DOM element, then I would say that you can safely assume evt.target. is an Element. I don't think this is an matter of cross-browser behavior. Merely that EventTarget is a more abstract interface than Element.

Swift 4.1 Updated Xcode 9.2

if let filePath = Bundle.main.path(forResource: "fileName", ofType: "json"), let data = NSData(contentsOfFile: filePath) {

     do {
      let json = try JSONSerialization.jsonObject(with: data as Data, options: JSONSerialization.ReadingOptions.allowFragments)        
        }
     catch {
                //Handle error
           }
 }

In old school JavaScript, you could do this:

document.body.innerHTML = '<p id="foo">Some HTML</p>' + document.body.innerHTML;

In response to your comment:

[...] I was interested in declaring the source of a new element's attributes and events, not the innerHTML of an element.

You need to inject the new HTML into the DOM, though; that's why innerHTML is used in the old school JavaScript example. The innerHTML of the BODY element is prepended with the new HTML. We're not really touching the existing HTML inside the BODY.

I'll rewrite the abovementioned example to clarify this:

var newElement = '<p id="foo">This is some dynamically added HTML. Yay!</p>';
var bodyElement = document.body;
bodyElement.innerHTML = newElement + bodyElement.innerHTML;
// note that += cannot be used here; this would result in 'NaN'

Using a JavaScript framework would make this code much less verbose and improve readability. For example, jQuery allows you to do the following:

$('body').prepend('<p id="foo">Some HTML</p>');

There are four options here:

1. Get virtualenv set up. Each virtual environment you create will automatically have pip.

2. Get pip set up globally.

3. Learn how to install Python packages manually—in most cases it's as simple as download, unzip, python setup.py install, but not always.

4. Use Christoph Gohlke's binary installers.

I have met a similar problem when checking emptiness in a component. In this case, the controller must define a method that actually performs the test and the view uses it:

function FormNumericFieldController(/*$scope, $element, $attrs*/ ) {
    var ctrl = this;

    ctrl.isEmptyObject = function(object) {
        return angular.equals(object, {});
    }
}

<!-- any validation error will trigger an error highlight -->
<span ng-class="{'has-error': !$ctrl.isEmptyObject($ctrl.formFieldErrorRef) }">
    <!-- validated control here -->
</span>

You are getting this error because the value cannot be found in the range. String or integer doesn't matter. Best thing to do in my experience is to do a check first to see if the value exists.

I used CountIf below, but there is lots of different ways to check existence of a value in a range.

Public Sub test()

Dim rng As Range
Dim aNumber As Long

aNumber = 666

Set rng = Sheet5.Range("B16:B615")

    If Application.WorksheetFunction.CountIf(rng, aNumber) > 0 Then

        rowNum = Application.WorksheetFunction.Match(aNumber, rng, 0)

    Else
        MsgBox aNumber & " does not exist in range " & rng.Address
    End If

End Sub

ALTERNATIVE WAY

Public Sub test()
    Dim rng As Range
    Dim aNumber As Variant
    Dim rowNum As Long

    aNumber = "2gg"

    Set rng = Sheet5.Range("B1:B20")

    If Not IsError(Application.Match(aNumber, rng, 0)) Then
        rowNum = Application.Match(aNumber, rng, 0)
        MsgBox rowNum
    Else
        MsgBox "error"
    End If
End Sub

OR

Public Sub test()
    Dim rng As Range
    Dim aNumber As Variant
    Dim rowNum As Variant

    aNumber = "2gg"

    Set rng = Sheet5.Range("B1:B20")

    rowNum = Application.Match(aNumber, rng, 0)

    If Not IsError(rowNum) Then
        MsgBox rowNum
    Else
        MsgBox "error"
    End If
End Sub

I've come across this thread when suffering the same error, after doing some research I can confirm, this is an error that happens when you try to decode a UTF-16 file with UTF-8.

With UTF-16 the first characther (2 bytes in UTF-16) is a Byte Order Mark (BOM), which is used as a decoding hint and doesn't appear as a character in the decoded string. This means the first byte will be either FE or FF and the second, the other.

Heavily edited after I found out the real answer

Try disabling the xcache or apc modules. Seems to cause a problem with some versions are saving objects to a session variable.

You can use this, pithy. :D

TextBox1.Focus();    
TextBox1.Select(0, TextBox1.Text.Length);

/// <summary>

/// </summary>
/// <param name="val"></param>

/// <param name="right"></param>
/// <returns></returns>
 public static string Formating(object val, int count, char space = ' ', bool right = false)
{
    var value = val.ToString();
    for (int i = 0; i < count - value.Length; i++) value = right ? value + space : space + value;
    return value;
}

"How can I directly (without saving the file on 2nd server) download the file from 1st server to client's machine?"

Just use the Client API and get the InputStream from the response

Client client = ClientBuilder.newClient();
String url = "...";
final InputStream responseStream = client.target(url).request().get(InputStream.class);

There are two flavors to get the InputStream. You can also use

Response response = client.target(url).request().get();
InputStream is = (InputStream)response.getEntity();

Which one is the more efficient? I'm not sure, but the returned InputStreams are different classes, so you may want to look into that if you care to.

From 2nd server I can get a ByteArrayOutputStream to get the file from 1st server, can I pass this stream further to the client using the REST service?

So most of the answers you'll see in the link provided by @GradyGCooper seem to favor the use of StreamingOutput. An example implementation might be something like

final InputStream responseStream = client.target(url).request().get(InputStream.class);
System.out.println(responseStream.getClass());
StreamingOutput output = new StreamingOutput() {
    @Override
    public void write(OutputStream out) throws IOException, WebApplicationException {  
        int length;
        byte[] buffer = new byte[1024];
        while((length = responseStream.read(buffer)) != -1) {
            out.write(buffer, 0, length);
        }
        out.flush();
        responseStream.close();
    }   
};
return Response.ok(output).header(
        "Content-Disposition", "attachment, filename=\"...\"").build();

But if we look at the source code for StreamingOutputProvider, you'll see in the writeTo, that it simply writes the data from one stream to another. So with our implementation above, we have to write twice.

How can we get only one write? Simple return the InputStream as the Response

final InputStream responseStream = client.target(url).request().get(InputStream.class);
return Response.ok(responseStream).header(
        "Content-Disposition", "attachment, filename=\"...\"").build();

If we look at the source code for InputStreamProvider, it simply delegates to ReadWriter.writeTo(in, out), which simply does what we did above in the StreamingOutput implementation

 public static void writeTo(InputStream in, OutputStream out) throws IOException {
    int read;
    final byte[] data = new byte[BUFFER_SIZE];
    while ((read = in.read(data)) != -1) {
        out.write(data, 0, read);
    }
}

Asides:

• Client objects are expensive resources. You may want to reuse the same Client for request. You can extract a WebTarget from the client for each request.

  WebTarget target = client.target(url);
  InputStream is = target.request().get(InputStream.class);
  

  I think the WebTarget can even be shared. I can't find anything in the Jersey 2.x documentation (only because it is a larger document, and I'm too lazy to scan through it right now :-), but in the Jersey 1.x documentation, it says the Client and WebResource (which is equivalent to WebTarget in 2.x) can be shared between threads. So I'm guessing Jersey 2.x would be the same. but you may want to confirm for yourself.

• You don't have to make use of the Client API. A download can be easily achieved with the java.net package APIs. But since you're already using Jersey, it doesn't hurt to use its APIs

• The above is assuming Jersey 2.x. For Jersey 1.x, a simple Google search should get you a bunch of hits for working with the API (or the documentation I linked to above)

UPDATE

I'm such a dufus. While the OP and I are contemplating ways to turn a ByteArrayOutputStream to an InputStream, I missed the simplest solution, which is simply to write a MessageBodyWriter for the ByteArrayOutputStream

import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.lang.annotation.Annotation;
import java.lang.reflect.Type;
import javax.ws.rs.WebApplicationException;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.MultivaluedMap;
import javax.ws.rs.ext.MessageBodyWriter;
import javax.ws.rs.ext.Provider;

@Provider
public class OutputStreamWriter implements MessageBodyWriter<ByteArrayOutputStream> {

    @Override
    public boolean isWriteable(Class<?> type, Type genericType,
            Annotation[] annotations, MediaType mediaType) {
        return ByteArrayOutputStream.class == type;
    }

    @Override
    public long getSize(ByteArrayOutputStream t, Class<?> type, Type genericType,
            Annotation[] annotations, MediaType mediaType) {
        return -1;
    }

    @Override
    public void writeTo(ByteArrayOutputStream t, Class<?> type, Type genericType,
            Annotation[] annotations, MediaType mediaType,
            MultivaluedMap<String, Object> httpHeaders, OutputStream entityStream)
            throws IOException, WebApplicationException {
        t.writeTo(entityStream);
    }
}

Then we can simply return the ByteArrayOutputStream in the response

return Response.ok(baos).build();

D'OH!

UPDATE 2

Here are the tests I used (

Resource class

@Path("test")
public class TestResource {

    final String path = "some_150_mb_file";

    @GET
    @Produces(MediaType.APPLICATION_OCTET_STREAM)
    public Response doTest() throws Exception {
        InputStream is = new FileInputStream(path);
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        int len;
        byte[] buffer = new byte[4096];
        while ((len = is.read(buffer, 0, buffer.length)) != -1) {
            baos.write(buffer, 0, len);
        }
        System.out.println("Server size: " + baos.size());
        return Response.ok(baos).build();
    }
}

Client test

public class Main {
    public static void main(String[] args) throws Exception {
        Client client = ClientBuilder.newClient();
        String url = "http://localhost:8080/api/test";
        Response response = client.target(url).request().get();
        String location = "some_location";
        FileOutputStream out = new FileOutputStream(location);
        InputStream is = (InputStream)response.getEntity();
        int len = 0;
        byte[] buffer = new byte[4096];
        while((len = is.read(buffer)) != -1) {
            out.write(buffer, 0, len);
        }
        out.flush();
        out.close();
        is.close();
    }
}

UPDATE 3

So the final solution for this particular use case was for the OP to simply pass the OutputStream from the StreamingOutput's write method. Seems the third-party API, required a OutputStream as an argument.

StreamingOutput output = new StreamingOutput() {
    @Override
    public void write(OutputStream out) {
        thirdPartyApi.downloadFile(.., .., .., out);
    }
}
return Response.ok(output).build();

Not quite sure, but seems the reading/writing within the resource method, using ByteArrayOutputStream`, realized something into memory.

The point of the downloadFile method accepting an OutputStream is so that it can write the result directly to the OutputStream provided. For instance a FileOutputStream, if you wrote it to file, while the download is coming in, it would get directly streamed to the file.

It's not meant for us to keep a reference to the OutputStream, as you were trying to do with the baos, which is where the memory realization comes in.

So with the way that works, we are writing directly to the response stream provided for us. The method write doesn't actually get called until the writeTo method (in the MessageBodyWriter), where the OutputStream is passed to it.

You can get a better picture looking at the MessageBodyWriter I wrote. Basically in the writeTo method, replace the ByteArrayOutputStream with StreamingOutput, then inside the method, call streamingOutput.write(entityStream). You can see the link I provided in the earlier part of the answer, where I link to the StreamingOutputProvider. This is exactly what happens

In case you get an error if myvar points to another variable, try this (suggested by @mherzog)-

 >> my_var = 5
>> my_var_name = [ k for k,v in locals().items() if v is my_var][0]
>> my_var_name 
'my_var'

locals() - Return a dictionary containing the current scope's local variables. by iterating through this dictionary we can check the key which has a value equal to the defined variable, just extracting the key will give us the text of variable in string format.

Implicit and Explicit Waits

Implicit Wait

An implicit wait is to tell WebDriver to poll the DOM for a certain amount of time when trying to find an element or elements if they are not immediately available. The default setting is 0. Once set, the implicit wait is set for the life of the WebDriver object instance.

driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

Explicit Wait + Expected Conditions

An explicit waits is code you define to wait for a certain condition to occur before proceeding further in the code. The worst case of this is Thread.sleep(), which sets the condition to an exact time period to wait. There are some convenience methods provided that help you write code that will wait only as long as required. WebDriverWait in combination with ExpectedCondition is one way this can be accomplished.

WebDriverWait wait = new WebDriverWait(driver, 10);
WebElement element = wait.until(
        ExpectedConditions.visibilityOfElementLocated(By.id("someid")));

Use HttpServerUtility.UrlEncode

The following should do the trick:

btn.Click += btn1_Click;

I think that you can bind the load event of the iframe, the event fires when the iframe content is fully loaded.

At the same time you can start a setTimeout, if the iFrame is loaded clear the timeout alternatively let the timeout fire.

Code:

var iframeError;

function change() {
    var url = $("#addr").val();
    $("#browse").attr("src", url);
    iframeError = setTimeout(error, 5000);
}

function load(e) {
    alert(e);
}

function error() {
    alert('error');
}

$(document).ready(function () {
    $('#browse').on('load', (function () {
        load('ok');
        clearTimeout(iframeError);
    }));

});

Demo: http://jsfiddle.net/IrvinDominin/QXc6P/

Second problem

It is because you miss the parens in the inline function call; try change this:

<iframe id="browse" style="width:100%;height:100%" onload="load" onerror="error"></iframe>

into this:

<iframe id="browse" style="width:100%;height:100%" onload="load('Done func');" onerror="error('failed function');"></iframe>

Demo: http://jsfiddle.net/IrvinDominin/ALBXR/4/

If you are talking about the scrollbar that automatically appears on a div with overflow: scroll (or auto), then no, that's still a native scrollbar rendered by the browser using normal OS widgets, and not something that can be styled(*).

Whilst you can replace it with a proxy made out of stylable divs and JavaScript as suggested by Matt, I wouldn't recommend it for the general case. Script-driven scrollbars never quite behave exactly the same as real OS scrollbars, causing usability and accessibility problems.

(*: Except for the IE colouring styles, which I wouldn't really recommend either. Apart from being IE-only, using them forces IE to fall back from using nice scrollbar images from the current Windows theme to ugly old Win95-style scrollbars.)

Just make sure the label is associated with the input.

  <label for="foo_baz">Baz</label>

After having to tackle this issue myself, I would like to build upon user854301's answer.

Mongoose ^4.13.8 I was able to use a function called toConstructor() which allowed me to avoid building the query multiple times when filters are applied. I know this function is available in older versions too but you'll have to check the Mongoose docs to confirm this.

The following uses Bluebird promises:

let schema = Query.find({ name: 'bloggs', age: { $gt: 30 } });

// save the query as a 'template'
let query = schema.toConstructor();

return Promise.join(
    schema.count().exec(),
    query().limit(limit).skip(skip).exec(),

    function (total, data) {
        return { data: data, total: total }
    }
);

Now the count query will return the total records it matched and the data returned will be a subset of the total records.

Please note the () around query() which constructs the query.

Normal ways would be Integer.toString(i) or String.valueOf(i).

int i = 5;
String strI = String.valueOf(i);

Or

int aInt = 1;    
String aString = Integer.toString(aInt);

Files being different only by a numerical string can be sorted on this number at the condition that it is preceded by a separator.

In this case, the following syntax can be used:

ls -x1 file | sort -t'<char>' -n -k2

Example:

ls -1 TRA*log | sort -t'_' -n -k2

I have written my own that you can use. This one works has sqlite, is thread safe and is in C++ for UNIX.

You should be able to pick it apart and use the C compatible code.

http://code.google.com/p/mountain-cms/

If you have access to your apache install and trust third-party code, you can use the apache upload progress module (if you use apache; there's also a nginx upload progress module).

Otherwise, you'd have to write a script that you can hit out of band to request the status of the file (checking the filesize of the tmp file for instance).

There's some work going on in firefox 3 I believe to add upload progress support to the browser, but that's not going to get into all the browsers and be widely adopted for a while (more's the pity).

In general you can say session.gc_maxlifetime specifies the maximum lifetime since the last change of your session data (not the last time session_start was called!). But PHP’s session handling is a little bit more complicated.

Because the session data is removed by a garbage collector that is only called by session_start with a probability of session.gc_probability devided by session.gc_divisor. The default values are 1 and 100, so the garbage collector is only started in only 1% of all session_start calls. That means even if the the session is already timed out in theory (the session data had been changed more than session.gc_maxlifetime seconds ago), the session data can be used longer than that.

Because of that fact I recommend you to implement your own session timeout mechanism. See my answer to How do I expire a PHP session after 30 minutes? for more details.

I'm on Ubuntu 14.04, with Bash version 4.3.11. However, I still don't have the fun built in string manipulation ${y,,}

This is what I used in my script to force capitalization:

CAPITALIZED=`echo "${y}" | tr '[a-z]' '[A-Z]'`

You can't do this in general, except at the window scope, where you can write window[objname].value = 'value';

I'd do it this way:

grid1.DataContext = dt.AsEnumerable().Where(x => x < 10).AsEnumerable().CopyToDataTable().AsDataView();

and do whatever query i want between the two AsEnumerable(). If you don't need space for query, you can just do directly this:

grid1.DataContext = dt.AsDataView();

Firstly, in histories_T, you are referencing table T_customer (should be T_customers) and secondly, you are missing the FOREIGN KEY clause that REFERENCES orders; which is not being created (or dropped) with the code you provided.

There may be additional errors as well, and I admit Oracle has never been very good at describing the cause of errors - "Mutating Tables" is a case in point.

Let me know if there additional problems you are missing.

I tried the above answer - using page.html#ID_name it gave me a 404 page doesn't exist error.

Then instead of using .html, I simply put a slash / before the # and that worked fine. So my example on the sending page between the link tags looks like:

<a href= "http://my website.com/target-page/#El_Chorro">El Chorro</a>

Just use / instead of .html.

The urllib2.HTTPError exception does not contain a getcode() method. Use the code attribute instead.

That may be overhead but should work.

double yourDouble = 1.05;
string stringForm = yourDouble.ToString();
int dotPosition = stringForm.IndexOf(".");
decimal decimalPart = Decimal.Parse("0" + stringForm.Substring(dotPosition));

Console.WriteLine(decimalPart); // 0.05

This is an extension method. See here for an explanation.

Extension methods allow developers to add new methods to the public contract of an existing CLR type, without having to sub-class it or recompile the original type. Extension Methods help blend the flexibility of "duck typing" support popular within dynamic languages today with the performance and compile-time validation of strongly-typed languages.

Extension Methods enable a variety of useful scenarios, and help make possible the really powerful LINQ query framework... .

it means that you can call

MyClass myClass = new MyClass();
int i = myClass.Foo();

rather than

MyClass myClass = new MyClass();
int i = Foo(myClass);

This allows the construction of fluent interfaces as stated below.

This is pure JavaScript.

There is nothing special about $. It is just a character that may be used in variable names.

var $ = 1;
var $$ = 2;
alert($ + $$);

jQuery just assigns it's core function to a variable called $. The code you have assigns this to a local variable called self and the results of calling jQuery with this as an argument to a global variable called $self.

It's ugly, dirty, confusing, but $, self and $self are all different variables that happen to have similar names.

For people who searched for php multidimensional array get values and actually want to solve problem comes from getting one column value from a 2 dimensinal array (like me!), here's a much elegant way than using foreach, which is array_column

For example, if I only want to get hotel_name from the below array, and form to another array:

$hotels = [
    [
        'hotel_name' => 'Hotel A',
        'info' => 'Hotel A Info',
    ],
    [
        'hotel_name' => 'Hotel B',
        'info' => 'Hotel B Info',
    ]
];

I can do this using array_column:

$hotel_name = array_column($hotels, 'hotel_name');

print_r($hotel_name); // Which will give me ['Hotel A', 'Hotel B']

For the actual answer for this question, it can also be beautified by array_column and call_user_func_array('array_merge', $twoDimensionalArray);

Let's make the data in PHP:

$hotels = [
    [
        'hotel_name' => 'Hotel A',
        'info' => 'Hotel A Info',
        'rooms' => [
            [
                'room_name' => 'Luxury Room',
                'bed' => 2,
                'boards' => [
                    'board_id' => 1,
                    'price' => 200
                ]
            ],
            [
                'room_name' => 'Non Luxy Room',
                'bed' => 4,
                'boards' => [
                    'board_id' => 2,
                    'price' => 150
                ]
            ],
        ]
    ],
    [
        'hotel_name' => 'Hotel B',
        'info' => 'Hotel B Info',
        'rooms' => [
            [
                'room_name' => 'Luxury Room',
                'bed' => 2,
                'boards' => [
                    'board_id' => 3,
                    'price' => 900
                ]
            ],
            [
                'room_name' => 'Non Luxy Room',
                'bed' => 4,
                'boards' => [
                    'board_id' => 4,
                    'price' => 300
                ]
            ],
        ]
    ]
];

And here's the calculation:

$rooms = array_column($hotels, 'rooms');
$rooms = call_user_func_array('array_merge', $rooms);
$boards = array_column($rooms, 'boards');

foreach($boards as $board){
    $board_id = $board['board_id'];
    $price = $board['price'];
    echo "Board ID is: ".$board_id." and price is: ".$price . "<br/>";
}

Which will give you the following result:

Board ID is: 1 and price is: 200
Board ID is: 2 and price is: 150
Board ID is: 3 and price is: 900
Board ID is: 4 and price is: 300

This is overcomplicated. An easier version of:

var rl = require('readline');
rl.createInterface... etc

would be to use

var rl = require('readline-sync');

then it will wait when you use

rl.question('string');

then it is easier to repeat. for example:

var rl = require('readline-sync');
for(let i=0;i<10;i++) {
    var ans = rl.question('What\'s your favourite food?');
    console.log('I like '+ans+' too!');
}

I find that the "solution" of just increasing the timeouts obscures what's really going on here, which is either

1. Your code and/or network calls are way too slow (should be sub 100 ms for a good user experience)
2. The assertions (tests) are failing and something is swallowing the errors before Mocha is able to act on them.

You usually encounter #2 when Mocha doesn't receive assertion errors from a callback. This is caused by some other code swallowing the exception further up the stack. The right way of dealing with this is to fix the code and not swallow the error.

When external code swallows your errors

In case it's a library function that you are unable to modify, you need to catch the assertion error and pass it onto Mocha yourself. You do this by wrapping your assertion callback in a try/catch block and pass any exceptions to the done handler.

it('should not fail', function (done) { // Pass reference here!

  i_swallow_errors(function (err, result) {
    try { // boilerplate to be able to get the assert failures
      assert.ok(true);
      assert.equal(result, 'bar');
      done();
    } catch (error) {
      done(error);
    }
  });
});

This boilerplate can of course be extracted into some utility function to make the test a little more pleasing to the eye:

it('should not fail', function (done) { // Pass reference here!
    i_swallow_errors(handleError(done, function (err, result) {
        assert.equal(result, 'bar');
    }));
});

// reusable boilerplate to be able to get the assert failures
function handleError(done, fn) {
    try { 
        fn();
        done();
    } catch (error) {
        done(error);
    }
}

Speeding up network tests

Other than that I suggest you pick up the advice on starting to use test stubs for network calls to make tests pass without having to rely on a functioning network. Using Mocha, Chai and Sinon the tests might look something like this

describe('api tests normally involving network calls', function() {

    beforeEach: function () {
        this.xhr = sinon.useFakeXMLHttpRequest();
        var requests = this.requests = [];

        this.xhr.onCreate = function (xhr) {
            requests.push(xhr);
        };
    },

    afterEach: function () {
        this.xhr.restore();
    }


    it("should fetch comments from server", function () {
        var callback = sinon.spy();
        myLib.getCommentsFor("/some/article", callback);
        assertEquals(1, this.requests.length);

        this.requests[0].respond(200, { "Content-Type": "application/json" },
                                 '[{ "id": 12, "comment": "Hey there" }]');
        expect(callback.calledWith([{ id: 12, comment: "Hey there" }])).to.be.true;
    });

});

See Sinon's nise docs for more info.

If you are getting back a sun.awt.image.ToolkitImage, you can cast the Image to that, and then use getBufferedImage() to get the BufferedImage.

So instead of your last line of code where you are casting you would just do:

BufferedImage buffered = ((ToolkitImage) image).getBufferedImage();

I think this solution uses less code and is easy to understand even for newbie.

For string field in struct, you can use pointer and reassigning the string to that pointer will be straightforward and simpler.

Define definition of struct:

typedef struct {
  int number;
  char *name;
  char *address;
  char *birthdate;
  char gender;
} Patient;

Initialize variable with type of that struct:

Patient patient;
patient.number = 12345;
patient.address = "123/123 some road Rd.";
patient.birthdate = "2020/12/12";
patient.gender = "M";

It is that simple. Hope this answer helps many developers.

You could also reuse SwingConstants.{LEFT,RIGHT}. They are not enums, but they do already exist and are used in many places.

Now iOS 7 devices – are always returning a MAC address of 02:00:00:00:00:00.

So better use [UIDevice identifierForVendor].

so better to call this method to get app specific unique key

Category will more suitable

import "UIDevice+Identifier.h"

- (NSString *) identifierForVendor1
{
    if ([[UIDevice currentDevice] respondsToSelector:@selector(identifierForVendor)]) {
        return [[[UIDevice currentDevice] identifierForVendor] UUIDString];
    }
    return @"";
}

Now call above method to get unique address

NSString *like_UDID=[NSString stringWithFormat:@"%@",
                [[UIDevice currentDevice] identifierForVendor1]];

NSLog(@"%@",like_UDID);

Element needs to be a variant, so you can't declare it as a string. Your function should accept a variant if it is a string though as long as you pass it ByVal.

Public Sub example()
    Dim sArray(4) As string
    Dim element As variant

    For Each element In sArray
        do_something (element)
    Next element
End Sub


Sub do_something(ByVal e As String)

End Sub

The other option is to convert the variant to a string before passing it.

  do_something CStr(element)

Change the checkboxes so that the name includes the index inside the brackets:

<input type="checkbox" class="checkbox_veh" id="checkbox_addveh<?php echo $i; ?>" <?php if ($vehicle_feature[$i]->check) echo "checked"; ?> name="feature[<?php echo $i; ?>]" value="<?php echo $vehicle_feature[$i]->id; ?>"> 

The checkboxes that aren't checked are never submitted. The boxes that are checked get submitted, but they get numbered consecutively from 0, and won't have the same indexes as the other corresponding input fields.

Andy Lester's response is accurate but I found an important extra step I needed to make to get this to work. In trying to get two profiles set up, one for personal and one for work, my ~/.ssh/config was roughly as follows:

Host me.github.com
    HostName github.com
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/me_rsa

Host work.github.com
    HostName github.com
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/work_rsa

My work profile didn't take until I did a ssh-add ~/.ssh/work_rsa. After that connections to github used the correct profile. Previously they defaulted to the first public key.

For Could not open a connection to your authentication agent when using ssh-add,
check: https://stackoverflow.com/a/17695338/1760313

Use the ternary operator

direction == 1 ? dosomething () : dosomethingelse ();

This is because of implicit conversion. The variables b, c, d are of float type. But the / operator sees two integers it has to divide and hence returns an integer in the result which gets implicitly converted to a float by the addition of a decimal point. If you want float divisions, try making the two operands to the / floats. Like follows.

#include <stdio.h>

int main() {
    int a;
    float b, c, d;
    a = 750;
    b = a / 350.0f;
    c = 750;
    d = c / 350;
    printf("%.2f %.2f", b, d);
    // output: 2.14 2.14
    return 0;
}

There's no need to redirect to a file and delete it later. Try:

Robocopy src dest > null 

Unless you're really worried about older browsers, you could just use the new html5 placeholder attribute like so:

<input type="text" name="email" placeholder="Email address" class="input" />

"create" is like playing GOD by taking things into our own hands. It is good for local debugging when you only want to work with the POD and not care abt Deployment/Replication Controller.

"apply" is playing by the rules. "apply" is like a master tool that helps you create and modify and requires nothing from you to manage the pods.

Try this:

<div class='content'>    
   @Html.Raw(HttpUtility.HtmlDecode(Model.Content))

Methods on a class act on the instance of the class, called the object.

class Example
{
   public int data = 0; // Each instance of Example holds its internal data. This is a "field", or "member variable".

   public void UpdateData() // .. and manipulates it (This is a method by the way)
   {
      data = data + 1;
   }

   public void PrintData() // This is also a method
   {
      Console.WriteLine(data);
   }
}

class Program
{
   public static void Main()
   {
       Example exampleObject1 = new Example();
       Example exampleObject2 = new Example();

       exampleObject1.UpdateData();
       exampleObject1.UpdateData();

       exampleObject2.UpdateData();

       exampleObject1.PrintData(); // Prints "2"
       exampleObject2.PrintData(); // Prints "1"
   }
}

How to generate the JPA Criteria Metamodel

The hibernate-jpamodelgen tool provided by Hibernate ORM can be used to scan the project entities and generate the JPA Criteria Metamodel. All you need to do is add the following annotationProcessorPath to the maven-compiler-plugin in the Maven pom.xml configuration file:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>${maven-compiler-plugin.version}</version>
    <configuration>
        <annotationProcessorPaths>
            <annotationProcessorPath>

Now, when the project is compiled, you can see that in the target folder, the following Java classes are generated:

Tag entity Metamodel

If the Tag entity is mapped as follows:

@Entity
@Table(name = "tag")
public class Tag {

    @Id
    private Long id;

    private String name;

    //Getters and setters omitted for brevity
}

The Tag_ Metamodel class is generated like this:

@Generated(value = "org.hibernate.jpamodelgen.JPAMetaModelEntityProcessor")
@StaticMetamodel(Tag.class)
public abstract class Tag_ {

    public static volatile SingularAttribute<Tag, String> name;
    public static volatile SingularAttribute<Tag, Long> id;

    public static final String NAME = "name";
    public static final String ID = "id";
}

The SingularAttribute is used for the basic id and name Tag JPA entity attributes.

Post entity Metamodel

The Post entity is mapped like this:

@Entity
@Table(name = "post")
public class Post {

    @Id
    private Long id;

    private String title;

    @OneToMany(
        mappedBy = "post",
        cascade = CascadeType.ALL,
        orphanRemoval = true
    )
    private List<PostComment> comments = new ArrayList<>();

    @OneToOne(
        mappedBy = "post",
        cascade = CascadeType.ALL,
        fetch = FetchType.LAZY
    )
    @LazyToOne(LazyToOneOption.NO_PROXY)
    private PostDetails details;

    @ManyToMany
    @JoinTable(
        name = "post_tag",
        joinColumns = @JoinColumn(name = "post_id"),
        inverseJoinColumns = @JoinColumn(name = "tag_id")
    )
    private List<Tag> tags = new ArrayList<>();
    
    //Getters and setters omitted for brevity
}

The Post entity has two basic attributes, id and title, a one-to-many comments collection, a one-to-one details association, and a many-to-many tags collection.

The Post_ Metamodel class is generated as follows:

@Generated(value = "org.hibernate.jpamodelgen.JPAMetaModelEntityProcessor")
@StaticMetamodel(Post.class)
public abstract class Post_ {

    public static volatile ListAttribute<Post, PostComment> comments;
    public static volatile SingularAttribute<Post, PostDetails> details;
    public static volatile SingularAttribute<Post, Long> id;
    public static volatile SingularAttribute<Post, String> title;
    public static volatile ListAttribute<Post, Tag> tags;

    public static final String COMMENTS = "comments";
    public static final String DETAILS = "details";
    public static final String ID = "id";
    public static final String TITLE = "title";
    public static final String TAGS = "tags";
}

The basic id and title attributes, as well as the one-to-one details association, are represented by a SingularAttribute while the comments and tags collections are represented by the JPA ListAttribute.

PostDetails entity Metamodel

The PostDetails entity is mapped like this:

@Entity
@Table(name = "post_details")
public class PostDetails {

    @Id
    @GeneratedValue
    private Long id;

    @Column(name = "created_on")
    private Date createdOn;

    @Column(name = "created_by")
    private String createdBy;

    @OneToOne(fetch = FetchType.LAZY)
    @MapsId
    @JoinColumn(name = "id")
    private Post post;
    
    //Getters and setters omitted for brevity
}

All entity attributes are going to be represented by the JPA SingularAttribute in the associated PostDetails_ Metamodel class:

@Generated(value = "org.hibernate.jpamodelgen.JPAMetaModelEntityProcessor")
@StaticMetamodel(PostDetails.class)
public abstract class PostDetails_ {

    public static volatile SingularAttribute<PostDetails, Post> post;
    public static volatile SingularAttribute<PostDetails, String> createdBy;
    public static volatile SingularAttribute<PostDetails, Long> id;
    public static volatile SingularAttribute<PostDetails, Date> createdOn;

    public static final String POST = "post";
    public static final String CREATED_BY = "createdBy";
    public static final String ID = "id";
    public static final String CREATED_ON = "createdOn";
}

PostComment entity Metamodel

The PostComment is mapped as follows:

@Entity
@Table(name = "post_comment")
public class PostComment {

    @Id
    private Long id;

    @ManyToOne(fetch = FetchType.LAZY)
    private Post post;

    private String review;
    
    //Getters and setters omitted for brevity
}

And, all entity attributes are represented by the JPA SingularAttribute in the associated PostComments_ Metamodel class:

@Generated(value = "org.hibernate.jpamodelgen.JPAMetaModelEntityProcessor")
@StaticMetamodel(PostComment.class)
public abstract class PostComment_ {

    public static volatile SingularAttribute<PostComment, Post> post;
    public static volatile SingularAttribute<PostComment, String> review;
    public static volatile SingularAttribute<PostComment, Long> id;

    public static final String POST = "post";
    public static final String REVIEW = "review";
    public static final String ID = "id";
}

Using the JPA Criteria Metamodel

Without the JPA Metamodel, a Criteria API query that needs to fetch the PostComment entities filtered by their associated Post title would look like this:

CriteriaBuilder builder = entityManager.getCriteriaBuilder();

CriteriaQuery<PostComment> query = builder.createQuery(PostComment.class);
Root<PostComment> postComment = query.from(PostComment.class);

Join<PostComment, Post> post = postComment.join("post");

query.where(
    builder.equal(
        post.get("title"),
        "High-Performance Java Persistence"
    )
);

List<PostComment> comments = entityManager
    .createQuery(query)
    .getResultList();

Notice that we used the post String literal when creating the Join instance, and we used the title String literal when referencing the Post title.

The JPA Metamodel allows us to avoid hard-coding entity attributes, as illustrated by the following example:

CriteriaBuilder builder = entityManager.getCriteriaBuilder();

CriteriaQuery<PostComment> query = builder.createQuery(PostComment.class);
Root<PostComment> postComment = query.from(PostComment.class);

Join<PostComment, Post> post = postComment.join(PostComment_.post);

query.where(
    builder.equal(
        post.get(Post_.title),
        "High-Performance Java Persistence"
    )
);

List<PostComment> comments = entityManager
    .createQuery(query)
    .getResultList();

Or, let's say we want to fetch a DTO projection while filtering the Post title and the PostDetails createdOn attributes.

We can use the Metamodel when creating the join attributes, as well as when building the DTO projection column aliases or when referencing the entity attributes we need to filter:

CriteriaBuilder builder = entityManager.getCriteriaBuilder();

CriteriaQuery<Object[]> query = builder.createQuery(Object[].class);

Root<PostComment> postComment = query.from(PostComment.class);
Join<PostComment, Post> post = postComment.join(PostComment_.post);

query.multiselect(
    postComment.get(PostComment_.id).alias(PostComment_.ID),
    postComment.get(PostComment_.review).alias(PostComment_.REVIEW),
    post.get(Post_.title).alias(Post_.TITLE)
);

query.where(
    builder.and(
        builder.like(
            post.get(Post_.title),
            "%Java Persistence%"
        ),
        builder.equal(
            post.get(Post_.details).get(PostDetails_.CREATED_BY),
            "Vlad Mihalcea"
        )
    )
);

List<PostCommentSummary> comments = entityManager
    .createQuery(query)
    .unwrap(Query.class)
    .setResultTransformer(Transformers.aliasToBean(PostCommentSummary.class))
    .getResultList();

Cool, right?

You can use below script.

var obj={1:"a",2:"b",c:"3"};
for (var x=Object.keys(obj),i=0;i<x.length,key=x[i],value=obj[key];i++){
    console.log(key,value);
}

outputs
1 a
2 b
c 3

You can add super privilege using phpmyadmin:

Go to PHPMYADMIN > privileges > Edit User > Under Administrator tab Click SUPER. > Go

If you want to do it through Console, do like this:

 mysql> GRANT SUPER ON *.* TO user@'localhost' IDENTIFIED BY 'password';

After executing above code, end it with:

mysql> FLUSH PRIVILEGES;

You should do in on *.* because SUPER is not the privilege that applies just to one database, it's global.

Just use this simple code in python.

Works only for windows OS.

from win32com.client import Dispatch

def speak(text):
    speak = Dispatch("SAPI.Spvoice")
    speak.Speak(text)

speak("How are you dugres?")

I personally use this.

I believe this is what you're looking for. It automatically scaled the video to fit the container.

DEMO: http://jsfiddle.net/t8qhgxuy/

Video need to have height and width always set to 100% of the parent.

HTML:

<div class="one"> CONTENT OVER VIDEO
    <video class="video-background" no-controls autoplay src="https://dl.dropboxusercontent.com/u/8974822/cloud-troopers-video.mp4" poster="http://thumb.multicastmedia.com/thumbs/aid/w/h/t1351705158/1571585.jpg"></video>
</div>

<div class="two">
    <video class="video-background" no-controls autoplay src="https://dl.dropboxusercontent.com/u/8974822/cloud-troopers-video.mp4" poster="http://thumb.multicastmedia.com/thumbs/aid/w/h/t1351705158/1571585.jpg"></video> CONTENT OVER VIDEO
</div>

CSS:

body {
    overflow: scroll;
    padding:  60px 20px;
}

.one {
    width: 90%;
    height: 30vw;
    overflow: hidden;
    border: 15px solid red;
    margin-bottom: 40px;
    position: relative;
}

.two{
    width: 30%;
    height: 300px;
    overflow: hidden;
    border: 15px solid blue;
    position: relative;
}

.video-background { /* class name used in javascript too */
    width: 100%; /* width needs to be set to 100% */
    height: 100%; /* height needs to be set to 100% */
    position: absolute;
    left: 0;
    top: 0;
    z-index: -1;
}

JS:

function scaleToFill() {
    $('video.video-background').each(function(index, videoTag) {
       var $video = $(videoTag),
           videoRatio = videoTag.videoWidth / videoTag.videoHeight,
           tagRatio = $video.width() / $video.height(),
           val;

       if (videoRatio < tagRatio) {
           val = tagRatio / videoRatio * 1.02; <!-- size increased by 2% because value is not fine enough and sometimes leaves a couple of white pixels at the edges -->
       } else if (tagRatio < videoRatio) {
           val = videoRatio / tagRatio * 1.02;
       }

       $video.css('transform','scale(' + val  + ',' + val + ')');

    });    
}

$(function () {
    scaleToFill();

    $('.video-background').on('loadeddata', scaleToFill);

    $(window).resize(function() {
        scaleToFill();
    });
});

Paxdiablo's answer is absolutely correct.

To avoid writing the return value 1 twice, I would use this instead:

=IF(OR(ISBLANK(A1),TRIM(A1)=""),1,0)

Well, you can always use window.crypto object available in the recent version of browser.

Just need one line of code to get a random number:

let n = window.crypto.getRandomValues(new Uint32Array(1))[0];

It also helps to encrypt and decrypt data. More information at MDN Web docs - window.crypto.

You can write extention method:

public static async Task<Tout> ReadAsAsync<Tout>(this System.Net.Http.HttpContent content) {
    return Newtonsoft.Json.JsonConvert.DeserializeObject<Tout>(await content.ReadAsStringAsync());
}

My issue was that I had overlapping names in the file paths for different types, like this:

<cache-path
    name="cached_files"
    path="." />
<external-cache-path
    name="cached_files"
    path="." />

After I changed the names ("cached_files") to be unique, I got rid of the error. My guess is that those paths are stored in some HashMap or something which does not allow duplicates.

Your regex ^[0-9] matches anything beginning with a digit, including strings like "1A". To avoid a partial match, append a $ to the end:

^[0-9]*$

This accepts any number of digits, including none. To accept one or more digits, change the * to +. To accept exactly one digit, just remove the *.

UPDATE: You mixed up the arguments to IsMatch. The pattern should be the second argument, not the first:

if (!System.Text.RegularExpressions.Regex.IsMatch(textbox.Text, "^[0-9]*$"))

CAUTION: In JavaScript, \d is equivalent to [0-9], but in .NET, \d by default matches any Unicode decimal digit, including exotic fare like ? (Myanmar 2) and ? (N'Ko 9). Unless your app is prepared to deal with these characters, stick with [0-9] (or supply the RegexOptions.ECMAScript flag).

To expand on previous answers, a function to do this could work like this (changing the time and interval formats however you like them according to this for function.date, and this for DateInterval):

(I've also written an alternate form of the below function here.)

// Return adjusted time.

function addMinutesToTime( $time, $plusMinutes ) {

    $time = DateTime::createFromFormat( 'g:i:s', $time );
    $time->add( new DateInterval( 'PT' . ( (integer) $plusMinutes ) . 'M' ) );
    $newTime = $time->format( 'g:i:s' );

    return $newTime;
}

$adjustedTime = addMinutesToTime( '9:15:00', 15 );

echo '<h1>Adjusted Time: ' . $adjustedTime . '</h1>' . PHP_EOL . PHP_EOL;

Here is my working solution :

// --------------------------
// SOAP Message creation
// --------------------------
SOAPMessage sm = MessageFactory.newInstance().createMessage();
sm.setProperty(SOAPMessage.WRITE_XML_DECLARATION, "true");
sm.setProperty(SOAPMessage.CHARACTER_SET_ENCODING, "UTF-8");

SOAPPart sp = sm.getSOAPPart();
SOAPEnvelope se = sp.getEnvelope();
se.setEncodingStyle("http://schemas.xmlsoap.org/soap/encoding/");
se.setAttribute("xmlns:SOAP-ENC", "http://schemas.xmlsoap.org/soap/encoding/");
se.setAttribute("xmlns:xsd", "http://www.w3.org/2001/XMLSchema");
se.setAttribute("xmlns:xsi", "http://www.w3.org/2001/XMLSchema-instance");

SOAPBody sb = sm.getSOAPBody();
// 
// Add all input fields here ...
// 

SOAPConnection connection = SOAPConnectionFactory.newInstance().createConnection();
// -----------------------------------
// URL creation with TimeOut connexion
// -----------------------------------
URL endpoint = new URL(null,
                      "http://myDomain/myWebService.php",
                    new URLStreamHandler() { // Anonymous (inline) class
                    @Override
                    protected URLConnection openConnection(URL url) throws IOException {
                    URL clone_url = new URL(url.toString());
                    HttpURLConnection clone_urlconnection = (HttpURLConnection) clone_url.openConnection();
                    // TimeOut settings
                    clone_urlconnection.setConnectTimeout(10000);
                    clone_urlconnection.setReadTimeout(10000);
                    return(clone_urlconnection);
                    }
                });


try {
    // -----------------
    // Send SOAP message
    // -----------------
    SOAPMessage retour = connection.call(sm, endpoint);
}
catch(Exception e) {
    if ((e instanceof com.sun.xml.internal.messaging.saaj.SOAPExceptionImpl) && (e.getCause()!=null) && (e.getCause().getCause()!=null) && (e.getCause().getCause().getCause()!=null)) {
        System.err.println("[" + e + "] Error sending SOAP message. Initial error cause = " + e.getCause().getCause().getCause());
    }
    else {
        System.err.println("[" + e + "] Error sending SOAP message.");

    }
}

If you're OK with using a library that writes the SQL for you, then you can use Upsert (currently Ruby and Python only):

Pet.upsert({:name => 'Jerry'}, :breed => 'beagle')
Pet.upsert({:name => 'Jerry'}, :color => 'brown')

That works across MySQL, Postgres, and SQLite3.

It writes a stored procedure or user-defined function (UDF) in MySQL and Postgres. It uses INSERT OR REPLACE in SQLite3.

You will have to access db through the ip of host machine, or if you want to access it via localhost:1521, then run webserver like -

docker run --net=host --name oracle-wls wls-image:latest

See here

Background

Absolute: The browser will always interpret / as the root of the hostname. For example, if my site was http://google.com/ and I specified /css/images.css then it would search for that at http://google.com/css/images.css. If your project root was actually at /myproject/ it would not find the css file. Therefore, you need to determine where your project folder root is relative to the hostname, and specify that in your href notation.

Relative: If you want to reference something you know is in the same path on the url - that is, if it is in the same folder, for example http://mysite.com/myUrlPath/index.html and http://mysite.com/myUrlPath/css/style.css, and you know that it will always be this way, you can go against convention and specify a relative path by not putting a leading / in front of your path, for example, css/style.css.

Filesystem Notations: Additionally, you can use standard filesystem notations like ... If you do http://google.com/images/../images/../images/myImage.png it would be the same as http://google.com/images/myImage.png. If you want to reference something that is one directory up from your file, use ../myFile.css.

Your Specific Case

In your case, you have two options:

• <link rel="stylesheet" type="text/css" href="/ServletApp/css/styles.css"/>
• <link rel="stylesheet" type="text/css" href="css/styles.css"/>

The first will be more concrete and compatible if you move things around, however if you are planning to keep the file in the same location, and you are planning to remove the /ServletApp/ part of the URL, then the second solution is better.

From the official jQuery documentation

• .mouseover()
  Bind an event handler to the "mouseover" JavaScript event, or trigger that event on an element.

• .hover() Bind one or two handlers to the matched elements, to be executed when the mouse pointer enters and leaves the elements.

  Calling $(selector).hover(handlerIn, handlerOut) is shorthand for: $(selector).mouseenter(handlerIn).mouseleave(handlerOut);

• .mouseenter()

  Bind an event handler to be fired when the mouse enters an element, or trigger that handler on an element.

  mouseover fires when the pointer moves into the child element as well, while mouseenter fires only when the pointer moves into the bound element.

What this means

Because of this, .mouseover() is not the same as .hover(), for the same reason .mouseover() is not the same as .mouseenter().

$('selector').mouseover(over_function) // may fire multiple times

// enter and exit functions only called once per element per entry and exit
$('selector').hover(enter_function, exit_function) 

Short answer:

StandardOutput=file:/var/log1.log
StandardError=file:/var/log2.log

If you don't want the files to be cleared every time the service is run, use append instead:

StandardOutput=append:/var/log1.log
StandardError=append:/var/log2.log

The thread's a little old. But from the title I thought it had promise for my needs. Unfortunately, my structure didn't lend itself easily to the nth-of-type solution. Here's a Thymeleaf solution.

}
.back-green {
  background-color:green;
}

I recommended you reading this: Normalization in DOM parsing with java - how does it work?

Example source.

For iOS13

For background pushes in iOS13, you must set below parameters:

apns-priority = 5
apns-push-type = background
//Required for WatchOS
//Highly recommended for Other platforms

Another option that may be useful is a dedicated HTTP debugging tool. There's a few available, I'd suggest HTTP Toolkit: an open-source project I've been working on (yeah, I might be biased) to solve this same problem for myself.

The main difference is usability & power. The Chrome dev tools are good for simple things, and I'd recommend starting there, but if you're struggling to understand the information there, and you need either more explanation or more power then proper focused tools can be useful!

For this case, it'll show you the full POST body you're looking for, with a friendly editor and highlighting (all powered by VS Code) so you can dig around. It'll give you the request & response headers of course, but with extra info like docs from MDN (the Mozilla Developer Network) for every standard header and status code you can see.

A picture is worth a thousand StackOverflow answers:

closest() only looks for parents, I'm guessing what you really want is .find()

$(this).closest('.row').children('.column').find('.inputQty').val();

I tried 228px radius for 1024x1024 and it worked :)

Note: z-index only works on positioned elements (position:absolute, position:relative, or position:fixed). Use one of those.

first of all;

a Fragment must be inside a FragmentActivity, that's the first rule,

a FragmentActivity is quite similar to a standart Activity that you already know, besides having some Fragment oriented methods

second thing about Fragments, is that there is one important method you MUST call, wich is onCreateView, where you inflate your layout, think of it as the setContentLayout

here is an example:

    @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {     mView       = inflater.inflate(R.layout.fragment_layout, container, false);       return mView; } 

and continu your work based on that mView, so to find a View by id, call mView.findViewById(..);

for the FragmentActivity part:

the xml part "must" have a FrameLayout in order to inflate a fragment in it

        <FrameLayout             android:id="@+id/content_frame"             android:layout_width="match_parent"             android:layout_height="match_parent"  >         </FrameLayout> 

as for the inflation part

getSupportFragmentManager().beginTransaction().replace(R.id.content_frame, new YOUR_FRAGMENT, "TAG").commit();

begin with these, as there is tons of other stuf you must know about fragments and fragment activities, start of by reading something about it (like life cycle) at the android developer site

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

• Java Documentation
• Java Tutorial

Example

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

Give the div "runat="server" and an id and you can reference it in your code behind.

<div runat="server" id="theDiv">

In code behind:

{
    theDiv.Visible = false;
}

You can cut using following ,
-d: delimiter ,-f for fields
\t used for tab separated fields

cut -d$'\t' -f 1-3,7-

You can use the parse() function to convert the characters into an expression. You need to specify that the input is text, because parse expects a file by default:

eval(parse(text="5+5"))

What about Transactions? They have the ROLLBACK-Feature.

@see https://dev.mysql.com/doc/refman/5.0/en/commit.html

For example:

START TRANSACTION;
SELECT * FROM nicetable WHERE somthing=1;
UPDATE nicetable SET nicefield='VALUE' WHERE somthing=1;
SELECT * FROM nicetable WHERE somthing=1; #check

COMMIT;
# or if you want to reset changes 
ROLLBACK;

SELECT * FROM nicetable WHERE somthing=1; #should be the old value

Answer on question from @rickozoe below:

In general these lines will not be executed as once. In PHP f.e. you would write something like that (perhaps a little bit cleaner, but wanted to answer quick ;-) ):

$MysqlConnection->query('START TRANSACTION;');
$erg = $MysqlConnection->query('UPDATE MyGuests SET lastname='Doe' WHERE id=2;');
if($erg)
    $MysqlConnection->query('COMMIT;');
else
    $MysqlConnection->query('ROLLBACK;');

Another way would be to use MySQL Variables (see https://dev.mysql.com/doc/refman/5.7/en/user-variables.html and https://stackoverflow.com/a/18499823/1416909 ):

# do some stuff that should be conditionally rollbacked later on

SET @v1 := UPDATE MyGuests SET lastname='Doe' WHERE id=2;
IF(v1 < 1) THEN
    ROLLBACK;
ELSE
    COMMIT;
END IF;

But I would suggest to use the language wrappers available in your favorite programming language.
