URLs use forward slashes (/), not backward ones (as windows). Try:

serverURLS = "https://abc.my.domain.com:55555/update";

The reason why you get the error is that the URL class can't parse the host part of the string and therefore, host is null.

I got the same error message when trying to connect to my SQL DB in Azure (using sql-cli). The simple solution was to escape the password with single quotes like this:

mssql -s server.database.windows.net -u user@server -p 'your_password' -d your_db -e

You can get the parameters you are asking for by typing:

dir /?

For the full list, try:

dir /s /b /a:d

You can use ClientScript.RegisterStartUpScript to inject javascript into the page on Page_Load.

Here's a link to MSDN reference: http://msdn.microsoft.com/en-us/library/asz8zsxy.aspx

Here's the code in Page_Load:

  List<string> tempString = new List<string>();
  tempString.Add("Hello");
  tempString.Add("World");

  StringBuilder sb = new StringBuilder();
  sb.Append("<script>");
  sb.Append("var testArray = new Array;");
  foreach(string str in tempString)
  {
    sb.Append("testArray.push('" + str + "');");
  }
  sb.Append("</script>");

  ClientScript.RegisterStartupScript(this.GetType(), "TestArrayScript", sb.ToString());

Notes: Use StringBuilder to build the script string as it will probably be long.

And here's the Javascript that checks for the injected array "testArray" before you can work with it:

if (testArray)
{
  // do something with testArray
}

There's 2 problems here:

1. Some consider this intrusive for C# to inject Javascript

2. We'll have to declare the array at a global context

If you can't live with that, another way would be to have the C# code save the Array into View State, then have the JavaScript use PageMethods (or web services) to call back to the server to get that View State object as an array. But I think that may be overkill for something like this.

getActionCommand()

Returns the command string associated with this action. This string allows a "modal" component to specify one of several commands, depending on its state. For example, a single button might toggle between "show details" and "hide details". The source object and the event would be the same in each case, but the command string would identify the intended action.

IMO, this is useful in case you a single command-component to fire different commands based on it's state, and using this method your handler can execute the right lines of code.

JTextField has JTextField#setActionCommand(java.lang.String) method that you can use to set the command string used for action events generated by it.

getSource()

Returns: The object on which the Event initially occurred.

We can use getSource() to identify the component and execute corresponding lines of code within an action-listener. So, we don't need to write a separate action-listener for each command-component. And since you have the reference to the component itself, you can if you need to make any changes to the component as a result of the event.

If the event was generated by the JTextField then the ActionEvent#getSource() will give you the reference to the JTextField instance itself.

The answer to this question lies in how C# Controls work

Controls in Windows Forms are bound to a specific thread and are not thread safe. Therefore, if you are calling a control's method from a different thread, you must use one of the control's invoke methods to marshal the call to the proper thread. This property can be used to determine if you must call an invoke method, which can be useful if you do not know what thread owns a control.

From Control.InvokeRequired

Effectively, what Invoke does is ensure that the code you are calling occurs on the thread that the control "lives on" effectively preventing cross threaded exceptions.

From a historical perspective, in .Net 1.1, this was actually allowed. What it meant is that you could try and execute code on the "GUI" thread from any background thread and this would mostly work. Sometimes it would just cause your app to exit because you were effectively interrupting the GUI thread while it was doing something else. This is the Cross Threaded Exception - imagine trying to update a TextBox while the GUI is painting something else.

• Which action takes priority?
• Is it even possible for both to happen at once?
• What happens to all of the other commands the GUI needs to run?

Effectively, you are interrupting a queue, which can have lots of unforeseen consequences. Invoke is effectively the "polite" way of getting what you want to do into that queue, and this rule was enforced from .Net 2.0 onward via a thrown InvalidOperationException.

To understand what is actually going on behind the scenes, and what is meant by "GUI Thread", it's useful to understand what a Message Pump or Message Loop is.

This is actually already answered in the question "What is a Message Pump" and is recommended reading for understanding the actual mechanism that you are tying into when interacting with controls.

Other reading you may find useful includes:

What's up with Begin Invoke

One of the cardinal rules of Windows GUI programming is that only the thread that created a control can access and/or modify its contents (except for a few documented exceptions). Try doing it from any other thread and you'll get unpredictable behavior ranging from deadlock, to exceptions to a half updated UI. The right way then to update a control from another thread is to post an appropriate message to the application message queue. When the message pump gets around to executing that message, the control will get updated, on the same thread that created it (remember, the message pump runs on the main thread).

and, for a more code heavy overview with a representative sample:

Invalid Cross-thread Operations

// the canonical form (C# consumer)

public delegate void ControlStringConsumer(Control control, string text);  // defines a delegate type

public void SetText(Control control, string text) {
    if (control.InvokeRequired) {
        control.Invoke(new ControlStringConsumer(SetText), new object[]{control, text});  // invoking itself
    } else {
        control.Text=text;      // the "functional part", executing only on the main thread
    }
}

Once you have an appreciation for InvokeRequired, you may wish to consider using an extension method for wrapping these calls up. This is ably covered in the Stack Overflow question Cleaning Up Code Littered with Invoke Required.

There is also a further write up of what happened historically that may be of interest.

Button button= (Button)findViewById(R.id.buttonId);
button.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View view) {
    // click handling code
   }
});

If zero doesn't work as the proper default value, you can use the component model to define a workaround for the enum:

[DefaultValue(None)]
public enum Orientation
{
     None = -1,
     North = 0,
     East = 1,
     South = 2,
     West = 3
 }

public static class Utilities
{
    public static TEnum GetDefaultValue<TEnum>() where TEnum : struct
    {
        Type t = typeof(TEnum);
        DefaultValueAttribute[] attributes = (DefaultValueAttribute[])t.GetCustomAttributes(typeof(DefaultValueAttribute), false);
        if (attributes != null &&
            attributes.Length > 0)
        {
            return (TEnum)attributes[0].Value;
        }
        else
        {
            return default(TEnum);
        }
    }
}

and then you can call:

Orientation o = Utilities.GetDefaultValue<Orientation>();
System.Diagnostics.Debug.Print(o.ToString());

Note: you will need to include the following line at the top of the file:

using System.ComponentModel;

This does not change the actual C# language default value of the enum, but gives a way to indicate (and get) the desired default value.

empty is an operator:

The empty operator is a prefix operation that can be used to determine whether a value is null or empty.

<c:if test="${empty myObject.featuresList}">

Consider the signal() function from the C standard:

extern void (*signal(int, void(*)(int)))(int);

Perfectly obscurely obvious - it's a function that takes two arguments, an integer and a pointer to a function that takes an integer as an argument and returns nothing, and it (signal()) returns a pointer to a function that takes an integer as an argument and returns nothing.

If you write:

typedef void (*SignalHandler)(int signum);

then you can instead declare signal() as:

extern  SignalHandler signal(int signum, SignalHandler handler);

This means the same thing, but is usually regarded as somewhat easier to read. It is clearer that the function takes an int and a SignalHandler and returns a SignalHandler.

It takes a bit of getting used to, though. The one thing you can't do, though is write a signal handler function using the SignalHandler typedef in the function definition.

I'm still of the old-school that prefers to invoke a function pointer as:

(*functionpointer)(arg1, arg2, ...);

Modern syntax uses just:

functionpointer(arg1, arg2, ...);

I can see why that works - I just prefer to know that I need to look for where the variable is initialized rather than for a function called functionpointer.

Sam commented:

I have seen this explanation before. And then, as is the case now, I think what I didn't get was the connection between the two statements:

    extern void (*signal(int, void()(int)))(int);  /*and*/

    typedef void (*SignalHandler)(int signum);
    extern SignalHandler signal(int signum, SignalHandler handler);

Or, what I want to ask is, what is the underlying concept that one can use to come up with the second version you have? What is the fundamental that connects "SignalHandler" and the first typedef? I think what needs to be explained here is what is typedef is actually doing here.

Let's try again. The first of these is lifted straight from the C standard - I retyped it, and checked that I had the parentheses right (not until I corrected it - it is a tough cookie to remember).

First of all, remember that typedef introduces an alias for a type. So, the alias is SignalHandler, and its type is:

a pointer to a function that takes an integer as an argument and returns nothing.

The 'returns nothing' part is spelled void; the argument that is an integer is (I trust) self-explanatory. The following notation is simply (or not) how C spells pointer to function taking arguments as specified and returning the given type:

type (*function)(argtypes);

After creating the signal handler type, I can use it to declare variables and so on. For example:

static void alarm_catcher(int signum)
{
    fprintf(stderr, "%s() called (%d)\n", __func__, signum);
}

static void signal_catcher(int signum)
{
    fprintf(stderr, "%s() called (%d) - exiting\n", __func__, signum);
    exit(1);
}

static struct Handlers
{
    int              signum;
    SignalHandler    handler;
} handler[] =
{
    { SIGALRM,   alarm_catcher  },
    { SIGINT,    signal_catcher },
    { SIGQUIT,   signal_catcher },
};

int main(void)
{
    size_t num_handlers = sizeof(handler) / sizeof(handler[0]);
    size_t i;

    for (i = 0; i < num_handlers; i++)
    {
        SignalHandler old_handler = signal(handler[i].signum, SIG_IGN);
        if (old_handler != SIG_IGN)
            old_handler = signal(handler[i].signum, handler[i].handler);
        assert(old_handler == SIG_IGN);
    }

    ...continue with ordinary processing...

    return(EXIT_SUCCESS);
}

^{Please note How to avoid using printf() in a signal handler?}

So, what have we done here - apart from omit 4 standard headers that would be needed to make the code compile cleanly?

The first two functions are functions that take a single integer and return nothing. One of them actually doesn't return at all thanks to the exit(1); but the other does return after printing a message. Be aware that the C standard does not permit you to do very much inside a signal handler; POSIX is a bit more generous in what is allowed, but officially does not sanction calling fprintf(). I also print out the signal number that was received. In the alarm_handler() function, the value will always be SIGALRM as that is the only signal that it is a handler for, but signal_handler() might get SIGINT or SIGQUIT as the signal number because the same function is used for both.

Then I create an array of structures, where each element identifies a signal number and the handler to be installed for that signal. I've chosen to worry about 3 signals; I'd often worry about SIGHUP, SIGPIPE and SIGTERM too and about whether they are defined (#ifdef conditional compilation), but that just complicates things. I'd also probably use POSIX sigaction() instead of signal(), but that is another issue; let's stick with what we started with.

The main() function iterates over the list of handlers to be installed. For each handler, it first calls signal() to find out whether the process is currently ignoring the signal, and while doing so, installs SIG_IGN as the handler, which ensures that the signal stays ignored. If the signal was not previously being ignored, it then calls signal() again, this time to install the preferred signal handler. (The other value is presumably SIG_DFL, the default signal handler for the signal.) Because the first call to 'signal()' set the handler to SIG_IGN and signal() returns the previous error handler, the value of old after the if statement must be SIG_IGN - hence the assertion. (Well, it could be SIG_ERR if something went dramatically wrong - but then I'd learn about that from the assert firing.)

The program then does its stuff and exits normally.

Note that the name of a function can be regarded as a pointer to a function of the appropriate type. When you do not apply the function-call parentheses - as in the initializers, for example - the function name becomes a function pointer. This is also why it is reasonable to invoke functions via the pointertofunction(arg1, arg2) notation; when you see alarm_handler(1), you can consider that alarm_handler is a pointer to the function and therefore alarm_handler(1) is an invocation of a function via a function pointer.

So, thus far, I've shown that a SignalHandler variable is relatively straight-forward to use, as long as you have some of the right type of value to assign to it - which is what the two signal handler functions provide.

Now we get back to the question - how do the two declarations for signal() relate to each other.

Let's review the second declaration:

 extern SignalHandler signal(int signum, SignalHandler handler);

If we changed the function name and the type like this:

 extern double function(int num1, double num2);

you would have no problem interpreting this as a function that takes an int and a double as arguments and returns a double value (would you? maybe you'd better not 'fess up if that is problematic - but maybe you should be cautious about asking questions as hard as this one if it is a problem).

Now, instead of being a double, the signal() function takes a SignalHandler as its second argument, and it returns one as its result.

The mechanics by which that can also be treated as:

extern void (*signal(int signum, void(*handler)(int signum)))(int signum);

are tricky to explain - so I'll probably screw it up. This time I've given the parameters names - though the names aren't critical.

In general, in C, the declaration mechanism is such that if you write:

type var;

then when you write var it represents a value of the given type. For example:

int     i;            // i is an int
int    *ip;           // *ip is an int, so ip is a pointer to an integer
int     abs(int val); // abs(-1) is an int, so abs is a (pointer to a)
                      // function returning an int and taking an int argument

In the standard, typedef is treated as a storage class in the grammar, rather like static and extern are storage classes.

typedef void (*SignalHandler)(int signum);

means that when you see a variable of type SignalHandler (say alarm_handler) invoked as:

(*alarm_handler)(-1);

the result has type void - there is no result. And (*alarm_handler)(-1); is an invocation of alarm_handler() with argument -1.

So, if we declared:

extern SignalHandler alt_signal(void);

it means that:

(*alt_signal)();

represents a void value. And therefore:

extern void (*alt_signal(void))(int signum);

is equivalent. Now, signal() is more complex because it not only returns a SignalHandler, it also accepts both an int and a SignalHandler as arguments:

extern void (*signal(int signum, SignalHandler handler))(int signum);

extern void (*signal(int signum, void (*handler)(int signum)))(int signum);

If that still confuses you, I'm not sure how to help - it is still at some levels mysterious to me, but I've grown used to how it works and can therefore tell you that if you stick with it for another 25 years or so, it will become second nature to you (and maybe even a bit quicker if you are clever).

select * from [Table_Name] limit 5

You can try to load the child component with history. to do so, pass 'history' through props. Something like that:

  return (
  <div>
    <Login history={this.props.history} />
    <br/>
    <Register/>
  </div>
)

You can always just export the registry, change the setting, then export the registry again and do a diff.

An example might help to show how commas can be displayed in a .csv file. Create a simple text file as follows:

Save this text file as a text file with suffix ".csv" and open it with Excel 2000 from Windows 10.

aa,bb,cc,d;d "In the spreadsheet presentation, the below line should look like the above line except the below shows a displayed comma instead of a semicolon between the d's." aa,bb,cc,"d,d", This works even in Excel

aa,bb,cc,"d,d", This works even in Excel 2000 aa,bb,cc,"d ,d", This works even in Excel 2000 aa,bb,cc,"d , d", This works even in Excel 2000

aa,bb,cc, " d,d", This fails in Excel 2000 due to the space belore the 1st quote aa,bb,cc, " d ,d", This fails in Excel 2000 due to the space belore the 1st quote aa,bb,cc, " d , d", This fails in Excel 2000 due to the space belore the 1st quote

aa,bb,cc,"d,d " , This works even in Excel 2000 even with spaces before and after the 2nd quote. aa,bb,cc,"d ,d " , This works even in Excel 2000 even with spaces before and after the 2nd quote. aa,bb,cc,"d , d " , This works even in Excel 2000 even with spaces before and after the 2nd quote.

Rule: If you want to display a comma in a a cell (field) of a .csv file: "Start and end the field with a double quotes, but avoid white space before the 1st quote"

Using val() didn't work for me. I had to use .attr() everywhere. Also I had different types of inputs and had to be pretty explicit in the case of check boxes and select menus.

Update textfield

$('#model_name').attr('value',nameVal);

Update image next to file input

$('#img-avatar').attr('src', avatarThumbUrl);

Update boolean

if (isActive) {
    $('#model_active').attr('checked',"checked");
} else {
    $('#model_active').attr('checked', null) ;
}

Update select (with number or string)

$('#model_framerate').children().each(function(i, el){
    var v = $(el).val();
    if (v === String(framerateVal)) { 
        $(el).attr('selected','selected');
    } else {
        $(el).attr('selected',null);
    }
}

From the matplotlib docs on scatter 1:

cmap is only used if c is an array of floats

So colorlist needs to be a list of floats rather than a list of tuples as you have it now. plt.colorbar() wants a mappable object, like the CircleCollection that plt.scatter() returns. vmin and vmax can then control the limits of your colorbar. Things outside vmin/vmax get the colors of the endpoints.

How does this work for you?

import matplotlib.pyplot as plt
cm = plt.cm.get_cmap('RdYlBu')
xy = range(20)
z = xy
sc = plt.scatter(xy, xy, c=z, vmin=0, vmax=20, s=35, cmap=cm)
plt.colorbar(sc)
plt.show()

If you plan on constructing HashMaps with variable depth, use a recursive data structure.

Below is an implementation providing a sample interface:

class NestedMap<K, V> {

    private final HashMap<K, NestedMap> child;
    private V value;

    public NestedMap() {
        child = new HashMap<>();
        value = null;
    }

    public boolean hasChild(K k) {
        return this.child.containsKey(k);
    }

    public NestedMap<K, V> getChild(K k) {
        return this.child.get(k);
    }

    public void makeChild(K k) {
        this.child.put(k, new NestedMap());
    }

    public V getValue() {
        return value;
    }

    public void setValue(V v) {
        value = v;
    }
}

and example usage:

class NestedMapIllustration {
    public static void main(String[] args) {

        NestedMap<Character, String> m = new NestedMap<>();

        m.makeChild('f');
        m.getChild('f').makeChild('o');
        m.getChild('f').getChild('o').makeChild('o');
        m.getChild('f').getChild('o').getChild('o').setValue("bar");

        System.out.println(
            "nested element at 'f' -> 'o' -> 'o' is " +
            m.getChild('f').getChild('o').getChild('o').getValue());
    }
}

I don't know if this is still going. But something like this is what I ended up using (I keep a session object on each connected socket, which in turn contains the username and other info:

var connectedUsers = Object.keys(io.sockets.connected).map(function(socketId) {
    return io.sockets.connected[socketId].session.username;
});

.extend() is added by many third-party libraries to make it easy to create objects from other objects. See http://api.jquery.com/jQuery.extend/ or http://www.prototypejs.org/api/object/extend for some examples.

.prototype refers to the "template" (if you want to call it that) of an object, so by adding methods to an object's prototype (you see this a lot in libraries to add to String, Date, Math, or even Function) those methods are added to every new instance of that object.

There's several different ways of doing this, with varying efficiency, depending on how good your query optimiser is, and the relative size of your two tables:

This is the shortest statement, and may be quickest if your phone book is very short:

SELECT  *
FROM    Call
WHERE   phone_number NOT IN (SELECT phone_number FROM Phone_book)

alternatively (thanks to Alterlife)

SELECT *
FROM   Call
WHERE  NOT EXISTS
  (SELECT *
   FROM   Phone_book
   WHERE  Phone_book.phone_number = Call.phone_number)

or (thanks to WOPR)

SELECT * 
FROM   Call
LEFT OUTER JOIN Phone_Book
  ON (Call.phone_number = Phone_book.phone_number)
  WHERE Phone_book.phone_number IS NULL

(ignoring that, as others have said, it's normally best to select just the columns you want, not '*')

It is kind of screwy, but in a pinch you can use sed or awk to make small edits or remove text. Be careful with your regex targets of course and be aware that you're likely root on your container and might have to re-adjust permissions.

For example, removing a full line that contains text matching a regex:

awk '!/targetText/' file.txt > temp && mv temp file.txt

(More)

you can set the PictureBox BackColor proprty to Transparent

You can try to use:

where(date: p[:date]..Float::INFINITY)

equivalent in sql

WHERE (`date` >= p[:date])

The result is:

Note.where(user_id: current_user.id, notetype: p[:note_type], date: p[:date]..Float::INFINITY).order(:fecha, :created_at)

And I have changed too

order('date ASC, created_at ASC')

For

order(:fecha, :created_at)

Use a custom comparator:

Collections.sort(nodeList, new Comparator<DataNode>(){
     public int compare(DataNode o1, DataNode o2){
         if(o1.degree == o2.degree)
             return 0;
         return o1.degree < o2.degree ? -1 : 1;
     }
});

attr("dominant-baseline", "central")

Ran into a similar issue, in that creating custom error messages for my custom exceptions make ugly code. This was my solution:

class MyRunTimeException: public std::runtime_error
{
public:
      MyRunTimeException(const std::string &filename):std::runtime_error(GetMessage(filename)) {}
private:
      static std::string GetMessage(const std::string &filename)
     {
           // Do your message formatting here. 
           // The benefit of returning std::string, is that the compiler will make sure the buffer is good for the length of the constructor call
           // You can use a local std::ostringstream here, and return os.str()
           // Without worrying that the memory is out of scope. It'll get copied
           // You also can create multiple GetMessage functions that take all sorts of objects and add multiple constructors for your exception
     }
}

This separates the logic for creating the messages. I had originally thought about overriding what(), but then you have to capture your message somewhere. std::runtime_error already has an internal buffer.

$link = mysqli_connect('127.0.0.1', 'my_user', 'my_pass', 'my_db');
mysqli_query($link, "INSERT INTO mytable (1, 2, 3, 'blah')");
$id = mysqli_insert_id($link);

See mysqli_insert_id().

Whatever you do, don't insert and then do a "SELECT MAX(id) FROM mytable". Like you say, it's a race condition and there's no need. mysqli_insert_id() already has this functionality.

In Ruby 1.9.2 and above they added a .to_date function to DateTime:

http://ruby-doc.org/stdlib-1.9.2/libdoc/date/rdoc/DateTime.html#method-i-to_date

This instance method doesn't appear to be present in earlier versions like 1.8.7.

You can just redirect in your success handler, like this:

window.location.href = "thankyou.php";

Or since you're displaying results, wait a few seconds, for example this would wait 2 seconds:

setTimeout(function() {
  window.location.href = "thankyou.php";
}, 2000);

By default, Valgrind writes its output to stderr. So you need to do something like:

valgrind a.out > log.txt 2>&1

Alternatively, you can tell Valgrind to write somewhere else; see http://valgrind.org/docs/manual/manual-core.html#manual-core.comment (but I've never tried this).

The datetime answer by tzaman is much cleaner, but you can do it with the original python time module:

import time
strings = time.strftime("%Y,%m,%d,%H,%M,%S")
t = strings.split(',')
numbers = [ int(x) for x in t ]
print numbers

Output:

[2016, 3, 11, 8, 29, 47]

I had the same problem: when click on the "Opens the Android SDK Manager", a pop out error message says “Location of the Android SDK has not been setup in the preference”. The delete and add again update address in "install new software" doesn't work for me.

I went to the ../android/android-sdk-windows and click the SDK Manager.exe. This works for me.

So I think after I updated the SDK, the eclipse cannot trigger the SDK Manager currently. But it can run by itself outside of eclipse.

you can just do this:

? ~ sudo docker rmi 4ed13257bb55 -f Deleted: sha256:4ed13257bb5512b975b316ef482592482ca54018a7728ea1fc387e873a68c358 Deleted: sha256:4a478ca02e8d2336595dcbed9c4ce034cd15f01229733e7d93a83fbb3a9026d3 Deleted: sha256:96df41d1ce6065cf75d05873fb1f9ea9fed0ca86addcfcec7722200ed3484c69 Deleted: sha256:d95efe864c7096c38757b80fddad12819fffd68ac3cc73333ebffaa42385fded

Compiling it with gcc requires you to pass a number of command line options. Compile it with g++ instead.

Always : If you always want vertical scrollbar, use overflow-y: scroll;

jsFiddle:

<div style="overflow-y: scroll;">
......
</div>

When needed: If you only want vertical scrollbar when needed, use overflow-y: auto; (You need to specify a height in this case)

jsFiddle:

<div style="overflow-y: auto; height:150px; ">
....
</div>

Since you are using bash, you don't need to create a child process for doing this. Here is one solution which performs it entirely within bash:

[[ $TEST =~ ^(.*):\ +(.*)$ ]] && TEST=${BASH_REMATCH[1]}:${BASH_REMATCH[2]}

Explanation: The groups before and after the sequence "colon and one or more spaces" are stored by the pattern match operator in the BASH_REMATCH array.

As I said in a comment to aqingsao's answer, it doesn't quite work when the textarea has newline characters, at least on Windows.

I've change his answer slightly thus:

$(function() {
    $("textarea[maxlength]").bind('input propertychange', function() {
        var maxLength = $(this).attr('maxlength');
        //I'm guessing JavaScript is treating a newline as one character rather than two so when I try to insert a "max length" string into the database I get an error.
        //Detect how many newlines are in the textarea, then be sure to count them twice as part of the length of the input.
        var newlines = ($(this).val().match(/\n/g) || []).length
        if ($(this).val().length + newlines > maxLength) {
            $(this).val($(this).val().substring(0, maxLength - newlines));
        }
    })
});

Now when I try to paste a lot of data in with newlines, I get exactly the right number of characters.

try

document.getElementsByClassName('myclass').length

let num = document.getElementsByClassName('myclass').length;_x000D_
console.log('Total "myclass" elements: '+num);

.myclass { color: red }

<span class="myclass" >1</span>_x000D_
<span>2</span>_x000D_
<span class="myclass">3</span>_x000D_
<span class="myclass">4</span>

as @MikeMiller pointed out, To exit scale mode: Right Ctrl (Host Key) + C
but for users who DON'T have a Right Ctrl (Host Key)
(such as MS Surface Pro users: we only have a Left Ctrl key), u need to go into Virtualbox>>File>>Preferences>>Input>>VirtualMachine tab>>change Host key Combination to one that works for ya(I used Ctrl+Shift+Alt which doesn't seem to be in use already)

First ensure that hlsearch is enabled by issuing the following command

:set hlsearch

You can also add this to your .vimrc file as set

set hlsearch

now when you use the quick search mechanism in command mode or a regular search command, all results will be highlighted. To move forward between results, press 'n' to move backwards press 'N'

In normal mode, to perform a quick search for the word under the cursor and to jump to the next occurrence in one command press '*', you can also search for the word under the cursor and move to the previous occurrence by pressing '#'

In normal mode, quick search can also be invoked with the

/searchterm<Enter>

to remove highlights on ocuurences use, I have bound this to a shortcut in my .vimrc

:nohl

Have a look at the system.web.script.serialization namespace (i think you will need .Net 3.5)

Just do System.out.println(e.getActionCommand()); inside actionPerformed(ActionEvent e) function. This will tell you which command is just performed.

or

if(e.getActionCommand().equals("Add")){

   System.out.println("Add button pressed");
}

I've just had some of the similar problems with scrollTop described here.

In the end I got around this on Firefox and IE by using the selector $('*').scrollTop(0);

Not perfect if you have elements you don't want to effect but it gets around the Document, Body, HTML and Window disparity. If it helps...

You need to overload operator << for mystruct class

Something like :-

friend ostream& operator << (ostream& os, const mystruct& m)
{
    os << m.m_a <<" " << m.m_b << endl;
    return os ;
}

See here

What might be easier, is to have two buttons and show/hide them in your functions. (ie. display:none|block;) Each button could then have it's own onclick with whatever code you need.

So, at first button1 would be display:block and button2 would be display:none. Then when you click button1 it would switch button2 to be display:block and button1 to be display:none.

Source location should be the URL (relative to the css file or full web location), not a file system full path, for example:

background: url("http://localhost/media/css/static/img/sprites/buttons-v3-10.png");
background: url("static/img/sprites/buttons-v3-10.png");

Alternatively, you can try to use file:/// protocol prefix.

Everything in S3 is an object. To you, it may be files and folders. But to S3, they're just objects.

Objects that end with the delimiter (/ in most cases) are usually perceived as a folder, but it's not always the case. It depends on the application. Again, in your case, you're interpretting it as a folder. S3 is not. It's just another object.

In your case above, the object users/<user-id>/contacts/<contact-id>/ exists in S3 as a distinct object, but the object users/<user-id>/ does not. That's the difference in your responses. Why they're like that, we cannot tell you, but someone made the object in one case, and didn't in the other. You don't see it in the AWS Management Console because the console is interpreting it as a folder and hiding it from you.

Since S3 just sees these things as objects, it won't "exclude" certain things for you. It's up to the client to deal with the objects as they should be dealt with.

Your Solution

Since you're the one that doesn't want the folder objects, you can exclude it yourself by checking the last character for a /. If it is, then ignore the object from the response.

you declare like this

 private boolean isSelectionRight;

write

 out.writeInt(isSelectionRight ? 1 : 0);

read

isSelectionRight  = in.readInt() != 0;

boolean type needs to be converted to something that Parcel supports and so we can convert it to int.

From What's the Difference between WCF and Web Services?

WCF is a replacement for all earlier web service technologies from Microsoft. It also does a lot more than what is traditionally considered as "web services".

WCF "web services" are part of a much broader spectrum of remote communication enabled through WCF. You will get a much higher degree of flexibility and portability doing things in WCF than through traditional ASMX because WCF is designed, from the ground up, to summarize all of the different distributed programming infrastructures offered by Microsoft. An endpoint in WCF can be communicated with just as easily over SOAP/XML as it can over TCP/binary and to change this medium is simply a configuration file mod. In theory, this reduces the amount of new code needed when porting or changing business needs, targets, etc.

ASMX is older than WCF, and anything ASMX can do so can WCF (and more). Basically you can see WCF as trying to logically group together all the different ways of getting two apps to communicate in the world of Microsoft; ASMX was just one of these many ways and so is now grouped under the WCF umbrella of capabilities.

Web Services can be accessed only over HTTP & it works in stateless environment, where WCF is flexible because its services can be hosted in different types of applications. Common scenarios for hosting WCF services are IIS,WAS, Self-hosting, Managed Windows Service.

The major difference is that Web Services Use XmlSerializer. But WCF Uses DataContractSerializer which is better in performance as compared to XmlSerializer.

When you declare a function within a function, the inner functions are only available in the scope in which they are declared, or in your case, the pad2 can only be called in the dmy scope.

All the variables existing in dmy are visible in pad2, but it doesn't happen the other way around :D

You could try passing a callback function to perform the replacement:

var tagsToReplace = {
    '&': '&',
    '<': '&lt;',
    '>': '&gt;'
};

function replaceTag(tag) {
    return tagsToReplace[tag] || tag;
}

function safe_tags_replace(str) {
    return str.replace(/[&<>]/g, replaceTag);
}

Here is a performance test: http://jsperf.com/encode-html-entities to compare with calling the replace function repeatedly, and using the DOM method proposed by Dmitrij.

Your way seems to be faster...

Why do you need it, though?

I might have even a simpler explanation to this question compared to the accepted answer so I'm going to give it a go: Assume this is the structure of the files and directories of a project:

Project root directory:
                       file1.php
                       file3.php
                       dir1/
                            file2.php

(dir1 is a directory and file2.php is inside it)

And this is the content of each of the three files above:

//file1.php:
<?php include "dir1/file2.php"

//file2.php:
<?php include "../file3.php"

//file3.php:
<?php echo "Hello, Test!";

Now run file1.php and try to guess what should happen. You might expect to see "Hello, Test!", however, it won't be shown! What you'll get instead will be an error indicating that the file you have requested(file3.php) does not exist!

The reason is that, inside file1.php when you include file2.php, the content of it is getting copied and then pasted back directly into file1.php which is inside the root directory, thus this part "../file3.php" runs from the root directory and thus goes one directory up the root! (and obviously it won't find the file3.php).

Now, what should we do ?!

Relative paths of course have the problem above, so we have to use absolute paths. However, absolute paths have also one problem. If you (for example) copy the root folder (containing your whole project) and paste it in anywhere else on your computer, the paths will be invalid from that point on! And that'll be a REAL MESS!

So we kind of need paths that are both absolute and dynamic(Each file dynamically finds the absolute path of itself wherever we place it)!

The way we do that is by getting help from PHP, and dirname() is the function to go for, which gives the absolute path to the directory in which a file exists in. And each file name could also be easily accessed using the __FILE__ constant. So dirname(__FILE__) would easily give you the absolute (while dynamic!) path to the file we're typing in the above code. Now move your whole project to a new place, or even a new system, and tada! it works!

So now if we turn the project above to this:

//file1.php:
<?php include(dirname(__FILE__)."/dir1/file2.php");

//file2.php:
<?php include(dirname(__FILE__)."/../file3.php");

//file3.php:
<?php echo "Hello, Test!";

if you run it, you'll see the almighty Hello, Test!! (hopefully, if you've not done anything else wrong).

It's also worth mentioning that from PHP5, a nicer way(with regards to readability and preventing eye boilage!) has been provided by PHP as well which is the constant __DIR__ which does exactly the same thing as dirname(__FILE__)!

Hope that helps.

Dataframes have a sort_index method which returns a copy by default. Pass inplace=True to operate in place.

import pandas as pd
df = pd.DataFrame([1, 2, 3, 4, 5], index=[100, 29, 234, 1, 150], columns=['A'])
df.sort_index(inplace=True)
print(df.to_string())

Gives me:

     A
1    4
29   2
100  1
150  5
234  3

The closed hand cursor is not 16x16. If you would need them in the same dimensions, here you have both of them in 16x16 px

Or if you need original cursors:

The following solution works for ASP.NET 5 (vNext) and it uses QueryHelpers class to build a URI with parameters.

    public Uri GetUri()
    {
        var location = _config.Get("http://iberia.com");
        Dictionary<string, string> values = GetDictionaryParameters();

        var uri = Microsoft.AspNetCore.WebUtilities.QueryHelpers.AddQueryString(location, values);
        return new Uri(uri);
    }

    private Dictionary<string,string> GetDictionaryParameters()
    {
        Dictionary<string, string> values = new Dictionary<string, string>
        {
            { "param1", "value1" },
            { "param2", "value2"},
            { "param3", "value3"}
        };
        return values;
    }

The result URI would have http://iberia.com?param1=value1&param2=value2&param3=value3

In case you actually mean what you seem to ask, I'll provide this alternative answer.

You say you want the dict to return a specified value, you do not say you want to set that value at the same time, like defaultdict does. This will do so:

class DictWithDefault(dict):
    def __init__(self, default, **kwargs):
        self.default = default
        super(DictWithDefault, self).__init__(**kwargs)

    def __getitem__(self, key):
        if key in self:
            return super(DictWithDefault, self).__getitem__(key)
        return self.default

Use like this:

d = DictWIthDefault(99, x=5, y=3)
print d["x"]   # 5
print d[42]    # 99
42 in d        # False
d[42] = 3
42 in d        # True

Alternatively, you can use a standard dict like this:

d = {3: 9, 4: 2}
default = 99
print d.get(3, default)  # 9
print d.get(42, default) # 99

Your Application Pool is in classic mode but your Application need integrated mode to fire. change it to Integrated Mode:

1. Open IIS Manager

2. Application Pool

3. Select pool that your app are run in it

4. In right panel select Basic Setting

5. Manage Pipeline Mode change to Integrated

Try this:

HTML

<div><span>Text</span></div>

CSS

div {
    height: 100px;
}

span {
    height: 100px;
    display: table-cell;
    vertical-align: middle;
}

Another option is to use

#include <process.h>
system("pause");

Though this is not very portable because it will only work on Windows, but it will automatically print

Press any key to continue...

This should work...

var displayDate = new Date().toLocaleDateString();

alert(displayDate);

But I suspect you are trying it on something else, for example:

var displayDate = Date.now.toLocaleDateString(); // No!

alert(displayDate);

That's the way I did it with pure JS:

var files = document.getElementById('filePoster');_x000D_
var submit = document.getElementById('submitFiles');_x000D_
var warning = document.getElementById('warning');_x000D_
files.addEventListener("change", function () {_x000D_
  if (files.files.length > 10) {_x000D_
    submit.disabled = true;_x000D_
    warning.classList += "warn"_x000D_
    return;_x000D_
  }_x000D_
  submit.disabled = false;_x000D_
});

#warning {_x000D_
    text-align: center;_x000D_
}_x000D_
_x000D_
#warning.warn {_x000D_
 color: red;_x000D_
 transform: scale(1.5);_x000D_
 transition: 1s all;_x000D_
}

<section id="shortcode-5" class="shortcode-5 pb-50">_x000D_
    <p id="warning">Please do not upload more than 10 images at once.</p>_x000D_
    <form class="imagePoster" enctype="multipart/form-data" action="/gallery/imagePoster" method="post">_x000D_
        <div class="input-group">_x000D_
       <input id="filePoster" type="file" class="form-control" name="photo" required="required" multiple="multiple" />_x000D_
     <button id="submitFiles" class="btn btn-primary" type="submit" name="button">Submit</button>_x000D_
        </div>_x000D_
    </form>_x000D_
</section>

This was the easier way for me:

pip2 install Name

So if you was using pip, try to use pip3 or pip2

It should solve the problem.

Use this plugin Moment Duration Format.

Example:

moment.duration(123, "minutes").format("h:mm");

Unless the writer of the executable has specifically provided a way for you to display a list of all the command line switches that it offers, then there is no way of doing this.

As Marcin suggests, the typical switches for displaying all of the options are either /? or /help (some applications might prefer the Unix-style syntax, -? and -help, respectively). But those are just a common convention.

If those don't work, you're out of luck. You'll need to check the documentation for the application, or perhaps try decompiling the executable (if you know what you're looking for).

One can think of document.write() (and .innerHTML) as evaluating a source code string. This can be very handy for many applications. For example if you get HTML code as a string from some source, it is handy to just "evaluate" it.

In the context of Lisp, DOM manipulation would be like manipulating a list structure, e.g. create the list (orange) by doing:

(cons 'orange '())

And document.write() would be like evaluating a string, e.g. create a list by evaluating a source code string like this:

(eval-string "(cons 'orange '())")

Lisp also has the very useful ability to create code using list manipulation (like using the "DOM style" to create a JS parse tree). This means you can build up a list structure using the "DOM style", rather than the "string style", and then run that code, e.g. like this:

(eval '(cons 'orange '()))

If you implement coding tools, like simple live editors, it is very handy to have the ability to quickly evaluate a string, for example using document.write() or .innerHTML. Lisp is ideal in this sense, but you can do very cool stuff also in JS, and many people are doing that, like http://jsbin.com/

It's quite unclear how you are computing the size ("the size in debug mode"?").

Use printf():

printf("the size of c is %u\n", (unsigned int) sizeof c);

Normally you'd print a size_t value (which is the type sizeof returns) with %zu, but if you're using a pre-C99 compiler like Visual Studio that won't work.

You need to find the typedef statements in your code that define the custom names like uint8 and so on; those are not standard so nobody here can know how they're defined in your code.

New C code should use <stdint.h> which gives you uint8_t and so on.

It seems you want to save your class instances across sessions, and using pickle is a decent way to do this. However, there's a package called klepto that abstracts the saving of objects to a dictionary interface, so you can choose to pickle objects and save them to a file (as shown below), or pickle the objects and save them to a database, or instead of use pickle use json, or many other options. The nice thing about klepto is that by abstracting to a common interface, it makes it easy so you don't have to remember the low-level details of how to save via pickling to a file, or otherwise.

Note that It works for dynamically added class attributes, which pickle cannot do...

You can do this simply by using pandas drop duplicates function

df.drop_duplicates(['A','B'],keep= 'last')

There is obviously another process listening on the port. You might find out that process by using the following command:

$ lsof -i :8000

or change your tornado app's port. tornado's error info not Explicitly on this.

In my case, the page needed to close, but may have been opened by a link and thus window.close would fail.

The solution I chose is to issue the window.close, followed by a window.setTimeout that redirects to a different page.

That way, if window.close succeeds, execution on that page stops, but if it fails, in a second, it will redirect to a different page.

window.close();
window.setTimeout(function(){location.href = '/some-page.php';},1000);

If you already know the item is a String, I prefer:

String itemText = (String) mySpinner.getSelectedItem();

Calling toString() on an Object that you know is a String seems like a more roundabout path than just casting the Object to String.

d3 also has a built-in range function. See https://github.com/mbostock/d3/wiki/Arrays#d3_range:

d3.range([start, ]stop[, step])

Generates an array containing an arithmetic progression, similar to the Python built-in range. This method is often used to iterate over a sequence of numeric or integer values, such as the indexes into an array. Unlike the Python version, the arguments are not required to be integers, though the results are more predictable if they are due to floating point precision. If step is omitted, it defaults to 1.

Example:

d3.range(10)
// returns [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

It's very easy. Try the below code

$(document).ready(function(){
  var hashValue = location.hash.replace(/^#/, '');  
  //do something with the value here  
});

go to : "C:\workspace.metadata.plugins\org.eclipse.e4.workbench"

if already you save backup file "workbench.xmi" replace it else delete this.

This worked for me:

}

            IsInArray = True
            Exit Function
        End If
    Next i
    IsInArray = False

End Function

Use like

IsInArray("example", Array("example", "someother text", "more things", "and another"))

You just need to have the full expression inside the $. Basically, you need "meters $10^1$". You don't need usetex=True to do this (or most any mathematical formula).

You may also want to use a raw string (e.g. r"\t", vs "\t") to avoid problems with things like \n, \a, \b, \t, \f, etc.

For example:

import matplotlib.pyplot as plt

fig, ax = plt.subplots()
ax.set(title=r'This is an expression $e^{\sin(\omega\phi)}$',
       xlabel='meters $10^1$', ylabel=r'Hertz $(\frac{1}{s})$')
plt.show()

If you don't want the superscripted text to be in a different font than the rest of the text, use \mathregular (or equivalently \mathdefault). Some symbols won't be available, but most will. This is especially useful for simple superscripts like yours, where you want the expression to blend in with the rest of the text.

import matplotlib.pyplot as plt

fig, ax = plt.subplots()
ax.set(title=r'This is an expression $\mathregular{e^{\sin(\omega\phi)}}$',
       xlabel='meters $\mathregular{10^1}$',
       ylabel=r'Hertz $\mathregular{(\frac{1}{s})}$')
plt.show()

For more information (and a general overview of matplotlib's "mathtext"), see: http://matplotlib.org/users/mathtext.html

Use the following jquery to submit a selectbox with out a submit button. Use "change" instead of click as shown above.

$("selectbox").change(function() { 
   document.forms["form"].submit();
});

In Windows 10 you might also want to delete Windows Explorer's override for file extension association:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.ps1\UserChoice

in addition to the HKEY_CLASSES_ROOT\Microsoft.PowerShellScript.1\Shell\open\command change mentioned in other answers.

See https://stackoverflow.com/a/2697804/1360907

I know this post is about adding a single line break but I thought I would mention that you can create multiple line breaks with the backslash (\) character:

Hello
\
\
\
World!

This would result in 3 new lines after "Hello". To clarify, that would mean 2 empty lines between "Hello" and "World!". It would display like this:

World!

Personally I find this cleaner for a large number of line breaks compared to using <br>.

Note that backslashes are not recommended for compatibility reasons. So this may not be supported by your Markdown parser but it's handy when it is.

If it is only to add a new tuple and you are sure that there are no collisions in the inner dictionary, you can do this:

def addNameToDictionary(d, tup):
    if tup[0] not in d:
        d[tup[0]] = {}
    d[tup[0]][tup[1]] = [tup[2]]

I found using css opacity is better for a simple show/hide hover, and you can add css3 transitions to make a nice finished hover effect. The transitions will just be dropped by older IE browsers, so it degrades gracefully to.

JS fiddle Demo

CSS

#stuff {
    opacity: 0.0;
    -webkit-transition: all 500ms ease-in-out;
    -moz-transition: all 500ms ease-in-out;
    -ms-transition: all 500ms ease-in-out;
    -o-transition: all 500ms ease-in-out;
    transition: all 500ms ease-in-out;
}
#hover {
    width:80px;
    height:20px;
    background-color:green;
    margin-bottom:15px;
}
#hover:hover + #stuff {
    opacity: 1.0;
}

HTML

<div id="hover">Hover</div>
<div id="stuff">stuff</div>

Swift 5.0, with generics:

func hideViewWithAnimation<T: UIView>(shouldHidden: Bool, objView: T) {
    if shouldHidden == true {
        UIView.animate(withDuration: 0.3, animations: {
            objView.alpha = 0
        }) { (finished) in
            objView.isHidden = shouldHidden
        }
    } else {
        objView.alpha = 0
        objView.isHidden = shouldHidden
        UIView.animate(withDuration: 0.3) {
            objView.alpha = 1
        }
    }
}   

Use:

hideViewWithAnimation(shouldHidden: shouldHidden, objView: itemCountLabelBGView)
hideViewWithAnimation(shouldHidden: shouldHidden, objView: itemCountLabel)
hideViewWithAnimation(shouldHidden: shouldHidden, objView: itemCountButton)

Here itemCountLabelBGView is a UIView, itemCountLabel is a UILabel & itemCountButton is a UIButton, So it will work for every view object whose parent class is UIView.

Regular expressions don't seem to work with the path() function with the following arguments: path(r'^$', views.index, name="index").

It should be like this: path('', views.index, name="index").

The 1st argument must be blank to enter a regular expression.

From now onwards after API 24, Uri.parse(filePath) won't work. You need to use this

final File videoFile = new File("path to your video file");
Uri fileUri = FileProvider.getUriForFile(mContext, "{yourpackagename}.fileprovider", videoFile);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(fileUri, "video/*");
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);//DO NOT FORGET THIS EVER
startActivity(intent);

But before using this you need to understand how file provider works. Go to official document link to understand file provider better.

You can use conda remove --force.

The documentation says:

--force               Forces removal of a package without removing packages
                      that depend on it. Using this option will usually
                      leave your environment in a broken and inconsistent
                      state

I am sure this can help. Create fileA anywhere in the directory and export all the functions.

export const func1=()=>{
    // do stuff
}
export const func2=()=>{
    // do stuff 
}
export const func3=()=>{
    // do stuff 
}
export const func4=()=>{
    // do stuff 
}
export const func5=()=>{
    // do stuff 
}

Here, in your React component class, you can simply write one import statement.

import React from 'react';
import {func1,func2,func3} from 'path_to_fileA';

class HtmlComponents extends React.Component {
    constructor(props){
        super(props);
        this.rippleClickFunction=this.rippleClickFunction.bind(this);
    }
    rippleClickFunction(){
        //do stuff. 
        // foo==bar
        func1(data);
        func2(data)
    }
   render() {
      return (
         <article>
             <h1>React Components</h1>
             <RippleButton onClick={this.rippleClickFunction}/>
         </article>
      );
   }
}

export default HtmlComponents;

Wrap the xml in another element

<wrapper>

The word "canonical" is just a synonym for "standard" or "usual". It doesn`t have any Java-specific meaning.

Just append a div with that class to body, then remove it when you're done:

// Show the backdrop
$('<div class="modal-backdrop"></div>').appendTo(document.body);

// Remove it (later)
$(".modal-backdrop").remove();

Live Example:

$("input").click(function() {_x000D_
  var bd = $('<div class="modal-backdrop"></div>');_x000D_
  bd.appendTo(document.body);_x000D_
  setTimeout(function() {_x000D_
    bd.remove();_x000D_
  }, 2000);_x000D_
});

<p>Click the button to get the backdrop for two seconds.</p>_x000D_

I know its already answered, but theres a better solution here use this code :

for ( Field f : context.getFields() ) {
     if ( f.getType() == String.class ) || ( f.getType() == String.class ) ) {
           //DO String To JSON
     }
     /// And so on...
}

This way you can access variables from class without manually typing them..

Faster and better .. Hope this helps.

Cheers. :D

You can create a camera intent and call it as startActivityForResult(intent).

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

   // start the image capture Intent
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);

I was working on same. Check below statement. Worked for me!!

SELECT * FROM [Schema].[Table] WHERE [Column] LIKE '%' + @Parameter + '%'

If we need only one column to be numeric

yyz$b <- as.numeric(as.character(yyz$b))

But, if all the columns needs to changed to numeric, use lapply to loop over the columns and convert to numeric by first converting it to character class as the columns were factor.

yyz[] <- lapply(yyz, function(x) as.numeric(as.character(x)))

Both the columns in the OP's post are factor because of the string "n/a". This could be easily avoided while reading the file using na.strings = "n/a" in the read.table/read.csv or if we are using data.frame, we can have character columns with stringsAsFactors=FALSE (the default is stringsAsFactors=TRUE)

Regarding the usage of apply, it converts the dataset to matrix and matrix can hold only a single class. To check the class, we need

lapply(yyz, class)

Or

sapply(yyz, class)

Or check

str(yyz)

• blitwizard
• load81
• egsl

Date.js has a lot of helpful date parsing methods.

require("datejs")

(new Date()).toString("yyyyMMdd")

This really comes down to how much you value your time. As the other posters have mentioned, there are a couple of ways you can build iPhone apps without a Mac. However, you are jumping through serious hoops, and it'll be much more difficult and take longer than it would with the proper development chain.

You can buy a second-hand Mac Mini for a couple of hundred bucks on eBay. If you're serious about doing iPhone development you'll make this back in saved time very quickly.

Access-Engine does not support

SELECT count(DISTINCT....) FROM ...

You have to do it like this:

SELECT count(*) 
FROM
(SELECT DISTINCT Name FROM table1)

Its a little workaround... you're counting a DISTINCT selection.

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

WebDriver driver = new FirefoxDriver();
driver.manage().timeouts().implicitlyWait(30,TimeUnit.SECONDS);
driver.get("http://www.google.com");

OR

import org.openqa.selenium.support.ui.ExpectedConditions;

WebDriverWait wait = new WebDriverWait(driver,30);
driver.get("http://www.google.com");
//hplogo is the id of Google logo on google.com
wait.until(ExpectedConditions.presenceOfElementLocated(By.id("hplogo")));

... Could not load file or assembly 'X' or one of its dependencies ...

Most likely it fails to load another dependency.

you could try to check the dependencies with a dependency walker.

I.e: https://www.dependencywalker.com/

Also check your build configuration (x86 / 64)

Edit: I also had this problem once when I was copying dlls in zip from a "untrusted" network share. The file was locked by Windows and the FileNotFoundException was raised.

See here: Detected DLLs that are from the internet and "blocked" by CASPOL

Wrong path: Project "cashes" the pointers to the images and if you have made name changes to the path for example Refactored package or folders. Then just simply write the R letter again and the editor suggests the right path and it will work. In this case your filenames are right and the content that is referred in the R. pointer is present but the path is wrong, thus clean and build won't work.

I prefer the first version to start a java application just because it has less pitfalls ("welcome to classpath hell"). The second one requires an executable jar file and the classpath for that application has to be defined inside the jar's manifest (all other classpath declaration will be silently ignored...). So with the second version you'd have to look into the jar, read the manifest and try to find out if the classpath entries are valid from where the jar is stored... That's avoidable.

I don't expect any performance advantages or disadvantages for either version. It's just telling the jvm which class to use for the main thread and where it can find the libraries.

I had the same problem when parsing html to string. Removing the last <p></p> (and replacing it with an alternative if desirable, like < /br>) solved it for me.

Inspired by the equation style provided in this answer, a more generic approach (more than one predictor + latex output as option) can be:

print_equation= function(model, latex= FALSE, ...){
    dots <- list(...)
    cc= model$coefficients
    var_sign= as.character(sign(cc[-1]))%>%gsub("1","",.)%>%gsub("-"," - ",.)
    var_sign[var_sign==""]= ' + '

    f_args_abs= f_args= dots
    f_args$x= cc
    f_args_abs$x= abs(cc)
    cc_= do.call(format, args= f_args)
    cc_abs= do.call(format, args= f_args_abs)
    pred_vars=
        cc_abs%>%
        paste(., x_vars, sep= star)%>%
        paste(var_sign,.)%>%paste(., collapse= "")

    if(latex){
        star= " \\cdot "
        y_var= strsplit(as.character(model$call$formula), "~")[[2]]%>%
            paste0("\\hat{",.,"_{i}}")
        x_vars= names(cc_)[-1]%>%paste0(.,"_{i}")
    }else{
        star= " * "
        y_var= strsplit(as.character(model$call$formula), "~")[[2]]        
        x_vars= names(cc_)[-1]
    }

    equ= paste(y_var,"=",cc_[1],pred_vars)
    if(latex){
        equ= paste0(equ," + \\hat{\\varepsilon_{i}} \\quad where \\quad \\varepsilon \\sim \\mathcal{N}(0,",
                    summary(MetamodelKdifEryth)$sigma,")")%>%paste0("$",.,"$")
    }
    cat(equ)
}

The model argument expects an lm object, the latex argument is a boolean to ask for a simple character or a latex-formated equation, and the ... argument pass its values to the format function.

I also added an option to output it as latex so you can use this function in a rmarkdown like this:

```{r echo=FALSE, results='asis'}
print_equation(model = lm_mod, latex = TRUE)
```

Now using it:

df <- data.frame(x = c(1:100))
df$y <- 2 + 3 * df$x + rnorm(100, sd = 40)
df$z <- 8 + 3 * df$x + rnorm(100, sd = 40)
lm_mod= lm(y~x+z, data = df)

print_equation(model = lm_mod, latex = FALSE)

This code yields: y = 11.3382963933174 + 2.5893419 * x + 0.1002227 * z

And if we ask for a latex equation, rounding the parameters to 3 digits:

print_equation(model = lm_mod, latex = TRUE, digits= 3)

This yields:

timestamp=$(awk 'BEGIN {srand(); print srand()}')

srand without a value uses the current timestamp with most Awk implementations.

The following MySQL statement should modify your column to accept NULLs.

ALTER TABLE `MyTable`
ALTER COLUMN `Col3` varchar(20) DEFAULT NULL

Best case for human logic to computer generated bytecode would be to utilize code like the following:

private double translateSlider(int sliderVal) {
  float retval = 1.0;

  switch (sliderVal) {
    case 1: retval = 0.9; break;
    case 2: retval = 0.8; break;
    case 3: retval = 0.7; break;
    case 4: retval = 0.6; break;
    case 0:
    default: break;
  }
  return retval;
}

Thus eliminating multiple exits from the method and utilizing the language logically. (ie while sliderVal is an integer range of 1-4 change float value else if sliderVal is 0 and all other values, retval stays the same float value of 1.0)

However something like this with each integer value of sliderVal being (n-(n/10)) one really could just do a lambda and get a faster results:

private double translateSlider = (int sliderVal) -> (1.0-(siderVal/10));

Edit: A modulus of 4 may be in order to keep logic (ie (n-(n/10))%4))

Two things to keep in mind Content-Type and the Encoding

1) What if the file is css

if (/.(css)$/.test(path)) {
  res.writeHead(200, {'Content-Type': 'text/css'}); 
  res.write(data, 'utf8');
} 

2) What if the file is jpg/png

if (/.(jpg)$/.test(path)) {
  res.writeHead(200, {'Content-Type': 'image/jpg'});
  res.end(data,'Base64');
}

Above one is just a sample code to explain the answer and not the exact code pattern.

I was able to cut and paste your code into a file and it ran correctly. If you execute it like this it should work:

Your "file.sh":

#!/bin/bash
# june 2011

if [ $# -lt 3 -o $# -gt 3 ]; then
   echo "Error... Usage: $0 host database username"
   exit 0
fi

The command:

$ ./file.sh arg1 arg2 arg3

Note that "file.sh" must be executable:

$ chmod +x file.sh

You may be getting that error b/c of how you're doing input (w/ a pipe, carrot, etc.). You could also try splitting the condition into two:

if [ $# -lt 3 ] || [ $# -gt 3 ]; then
   echo "Error... Usage: $0 host database username"
   exit 0
fi

Or, since you're using bash, you could use built-in syntax:

if [[ $# -lt 3 || $# -gt 3 ]]; then
   echo "Error... Usage: $0 host database username"
   exit 0
fi

And, finally, you could of course just check if 3 arguments were given (clean, maintains POSIX shell compatibility):

if [ $# -ne 3 ]; then
   echo "Error... Usage: $0 host database username"
   exit 0
fi

You need to escape it with two backslashes

\\?

See this for more details:

http://www.trans4mind.com/personal_development/JavaScript/Regular%20Expressions%20Simple%20Usage.htm

First of all you should stop using mysql_*. MySQL supports multiple inserting like

INSERT INTO example
VALUES
  (100, 'Name 1', 'Value 1', 'Other 1'),
  (101, 'Name 2', 'Value 2', 'Other 2'),
  (102, 'Name 3', 'Value 3', 'Other 3'),
  (103, 'Name 4', 'Value 4', 'Other 4');

You just have to build one string in your foreach loop which looks like that

$values = "(100, 'Name 1', 'Value 1', 'Other 1'), (100, 'Name 1', 'Value 1', 'Other 1'), (100, 'Name 1', 'Value 1', 'Other 1')";

and then insert it after the loop

$sql = "INSERT INTO email_list (R_ID, EMAIL, NAME) VALUES ".$values;

Another way would be Prepared Statements, which are even more suited for your situation.

Line width in ggplot2 can be changed with argument size= in geom_line().

#sample data
df<-data.frame(x=rnorm(100),y=rnorm(100))
ggplot(df,aes(x=x,y=y))+geom_line(size=2)

As other posters already indicated; your system clock is probably not synchronized up to microseconds to actual world time. Nonetheless are microsecond precision timestamps useful as a hybrid for both indicating current wall time, and measuring/profiling the duration of things.

I label all events/messages written to a log files using timestamps like "2012-10-21 19:13:45.267128". These convey both when it happened ("wall" time), and can also be used to measure the duration between this and the next event in the log file (relative difference in microseconds).

To achieve this, you need to link System.currentTimeMillis() with System.nanoTime() and work exclusively with System.nanoTime() from that moment forward. Example code:

/**
 * Class to generate timestamps with microsecond precision
 * For example: MicroTimestamp.INSTANCE.get() = "2012-10-21 19:13:45.267128"
 */ 
public enum MicroTimestamp 
{  INSTANCE ;

   private long              startDate ;
   private long              startNanoseconds ;
   private SimpleDateFormat  dateFormat ;

   private MicroTimestamp()
   {  this.startDate = System.currentTimeMillis() ;
      this.startNanoseconds = System.nanoTime() ;
      this.dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS") ;
   }

   public String get()
   {  long microSeconds = (System.nanoTime() - this.startNanoseconds) / 1000 ;
      long date = this.startDate + (microSeconds/1000) ;
      return this.dateFormat.format(date) + String.format("%03d", microSeconds % 1000) ;
   }
}

I don't see any mention of flexbox in here, so I will illustrate:

HTML

 <div class="wrapper">
   <div class="main">top</div>
   <div class="footer">bottom</div>
 </div>

CSS

 .wrapper {
   display: flex;
   flex-direction: column;
   min-height: 100vh;
  }
 .main {
   flex: 1;
 }
 .footer {
  flex: 0;
 }

The answer is in this line of the output of readelf -a in the original question

  [Requesting program interpreter: /lib/ld-linux.so.2]

I was missing the /lib/ld-linux.so.2 file, which is needed to run 32-bit apps. The Ubuntu package that has this file is libc6-i386.

These commands will help in overwriting code of demo branch into master

git fetch --all

Pull Your demo branch on local

git pull origin demo

Now checkout to master branch. This branch will be completely changed with the code on demo branch

git checkout master

Stay in the master branch and run this command.

git reset --hard origin/demo

reset means you will be resetting current branch

--hard is a flag that means it will be reset without raising any merge conflict

origin/demo will be the branch that will be considered to be the code that will forcefully overwrite current master branch

The output of the above command will show you your last commit message on origin/demo or demo branch

Then, in the end, force push the code on the master branch to your remote repo.

git push --force

So, not directly related but this is the first question that appears when you try to find how to terminate a process running from a specific folder using Python.

It also answers the question in a way(even though it is an old one with lots of answers).

While creating a faster way to scrape some government sites for data I had an issue where if any of the processes in the pool got stuck they would be skipped but still take up memory from my computer. This is the solution I reached for killing them, if anyone knows a better way to do it please let me know!

import pandas as pd
import wmi
from re import escape
import os

def kill_process(kill_path, execs):
    f = wmi.WMI()
    esc = escape(kill_path)
    temp = {'id':[], 'path':[], 'name':[]}
    for process in f.Win32_Process():
        temp['id'].append(process.ProcessId)
        temp['path'].append(process.ExecutablePath)
        temp['name'].append(process.Name)
    temp = pd.DataFrame(temp)
    temp = temp.dropna(subset=['path']).reset_index().drop(columns=['index'])
    temp = temp.loc[temp['path'].str.contains(esc)].loc[temp.name.isin(execs)].reset_index().drop(columns=['index'])
    [os.system('taskkill /PID {} /f'.format(t)) for t in temp['id']]

My best way to do this is, that i open the Code Definition Window, under View -> Code Definition Window or press Ctrl + W,D .

And then i got it floated and i have the definitions of methods in separate windows.

        if (timer.tick >= timerMaxSeconds) timer.cancel();
      });
    });
  }

  @override
  void initState() {
    startTimeout();
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return Row(
      mainAxisSize: MainAxisSize.min,
      children: <Widget>[
        Icon(Icons.timer),
        SizedBox(
          width: 5,
        ),
        Text(timerText)
      ],
    );
  }
}

You will get something like this

Not sure this is right on but when i copied some code form a paper on using pgmpy and pasted it into the editor under Spyder, i kept getting the "invalid character in identifier" error though it didn't look bad to me. The particular line was grade_cpd = TabularCPD(variable='G',\

For no good reason I replaced the ' with " throughout the code and it worked. Not sure why but it did work

You would have to find the position of the element in the DIV you want to scroll to, and set the scrollTop property.

divElem.scrollTop = 0;

Update:

Sample code to move up or down

  function move_up() {
    document.getElementById('divElem').scrollTop += 10;
  }

  function move_down() {
    document.getElementById('divElem').scrollTop -= 10;
  }

First, select all code using command+a

Second, hold key ctr and then press i

the whole selected code will nicely indent.

I know it's not XAML, but I did the same thing with SizeChanged event of the textbox:

private void TextBlock_SizeChanged(object sender, SizeChangedEventArgs e)
{
   TextBlock textBlock = sender as TextBlock;
   FrameworkElement element = textBlock.Parent as FrameworkElement;
   textBlock.Margin = new Thickness(0, 0, (element.ActualWidth / 100) * 20, 0);
}

The textbox appears to be 80% size of its parent (well right side margin is 20%) and stretches when needed.

I think best way is check if request is of type "OPTIONS" return 200 from middle ware. It worked for me.

express.use('*',(req,res,next) =>{
      if (req.method == "OPTIONS") {
        res.status(200);
        res.send();
      }else{
        next();
      }
    });

you can try this (I don't have sql server here today so I can't verify syntax, sorry)

select attributeName
  from tableName
 where CONVERT(varchar,attributeName,101) BETWEEN '03/01/2009' AND '03/31/2009'
   and CONVERT(varchar, attributeName,108) BETWEEN '06:00:00' AND '22:00:00'
   and DATEPART(day,attributeName) BETWEEN 2 AND 4

Here is a simplified running example of Seattle Ninja's solution.

var slideSource = document.getElementById('slideSource');_x000D_
_x000D_
document.getElementById('handle').onclick = function () {_x000D_
  slideSource.classList.toggle('fade');_x000D_
}

#slideSource {_x000D_
  opacity: 1;_x000D_
  transition: opacity 1s; _x000D_
}_x000D_
_x000D_
#slideSource.fade {_x000D_
  opacity: 0;_x000D_
}

<button id="handle">Fade</button> _x000D_
<div id="slideSource">Whatever you want here - images or text</div>

Yes, something like:

Class<?> clazz = Class.forName(className);
Constructor<?> ctor = clazz.getConstructor(String.class);
Object object = ctor.newInstance(new Object[] { ctorArgument });

That will only work for a single string parameter of course, but you can modify it pretty easily.

Note that the class name has to be a fully-qualified one, i.e. including the namespace. For nested classes, you need to use a dollar (as that's what the compiler uses). For example:

package foo;

public class Outer
{
    public static class Nested {}
}

To obtain the Class object for that, you'd need Class.forName("foo.Outer$Nested").

You are attempting to call wordlists here:

print  wordlists(len(words)) <--- Error here.

Try:

print wordlists[len(words)]

John's answer is correct. When I'm dealing with params I also need URLSearchParams interface:

this.props.history.push({
    pathname: '/client',
    search: "?" + new URLSearchParams({clientId: clientId}).toString()
})

You might also need to wrap your component with a withRouter HOC eg. export default withRouter(YourComponent);.

If you don't want to disable this exception, all you need to do is to let your application pump some messages at least once every 60 seconds. It will prevent this exception to happen. Try calling System.Threading.Thread.CurrentThread.Join(10) once in a while. There are other calls you can do that let the messages pump.

The accepted answer helped me update this both to PHP as well as CORS, so I thought I would include the solution for others:

pure PHP/HTML:

<?php // (the originating page, where you want to show the image)
// set your image location in whatever manner you need
$imageLocation = "http://example.com/exampleImage.png";

// set the location of your 'imageserve' program
$imageserveLocation = "https://example.com/imageserve.php";

// we'll look at the imageLocation and if it is already https, don't do anything, but if it is http, then run it through imageserve.php
$imageURL = (strstr("https://",$imageLocation)?"": $imageserveLocation . "?image=") . $imageLocation;

?>
<!-- this is the HTML image -->
<img src="<?php echo $imageURL ?>" />

javascript/jQuery:

<img id="theImage" src="" />
<script>
    var imageLocation = "http://example.com/exampleImage.png";
    var imageserveLocation = "https://example.com/imageserve.php";
    var imageURL = ((imageLocation.indexOf("https://") !== -1) ? "" : imageserveLocation + "?image=") + imageLocation;
    // I'm using jQuery, but you can use just javascript...        
    $("#theImage").prop('src',imageURL);
</script>

imageserve.php see http://stackoverflow.com/questions/8719276/cors-with-php-headers?noredirect=1&lq=1 for more on CORS

<?php
// set your secure site URL here (where you are showing the images)
$mySecureSite = "https://example.com";

// here, you can set what kinds of images you will accept
$supported_images = array('png','jpeg','jpg','gif','ico');

// this is an ultra-minimal CORS - sending trusted data to yourself 
header("Access-Control-Allow-Origin: $mySecureSite");

$parts = pathinfo($_GET['image']);
$extension = $parts['extension'];
if(in_array($extension,$supported_images)) {
    header("Content-Type: image/$extension");
    $image = file_get_contents($_GET['image']);
    echo $image;
}

Unfortunately, no. This feature is not available for facebook albums.

List list = new ArrayList(coll);
Collections.sort(list);

As Erel Segal Halevi says below, if coll is already a list, you can skip step one. But that would depend on the internals of TreeBidiMap.

List list;
if (coll instanceof List)
  list = (List)coll;
else
  list = new ArrayList(coll);

you can use jquery as follows

SCRIPT

  $('#IDOfyourdropdown').change(function(){
    alert($(this).val());
  });

FIDDLE is here

Yes: replace_all is one of the boost string algorithms:

Although it's not a standard library, it has a few things on the standard library:

1. More natural notation based on ranges rather than iterator pairs. This is nice because you can nest string manipulations (e.g., replace_all nested inside a trim). That's a bit more involved for the standard library functions.
2. Completeness. This isn't hard to be 'better' at; the standard library is fairly spartan. For example, the boost string algorithms give you explicit control over how string manipulations are performed (i.e., in place or through a copy).

This problem can be simply solved by closing Eclipse and restarting it. Eclipse sometimes fails to establish a connection with the Emulator, so this can happen in some cases.

Use data-dismiss="modal". In the version of Bootstrap I am using v3.3.5, when data-dismiss="modal" is added to the desired button like shown below it calls my external Javascript (JQuery) function beautifully and magically closes the modal. Its soo Sweet, I was worried I would have to call some modal hide in another function and chain that to the real working function

 <a href="#" id="btnReleaseAll" class="btn btn-primary btn-default btn-small margin-right pull-right" data-dismiss="modal">Yes</a>

In some external script file, and in my doc ready there is of course a function for the click of that identifier ID

 $("#divExamListHeader").on('click', '#btnReleaseAll', function () {
               // Do DatabaseMagic Here for a call a MVC ActionResult

The setInterval method returns an interval ID that you need to pass to clearInterval in order to clear the interval. You're passing a function, which won't work. Here's an example of a working setInterval/clearInterval

var interval_id = setInterval(myMethod,500);
clearInterval(interval_id);

Here's a quick overview that explains the different build targets.

From my own experience, if you're looking to build a project that will run on both x86 and x64 platforms, and you don't have any specific x64 optimizations, I'd change the build to specifically say "x86."

The reason for this is sometimes you can get some DLL files that collide or some code that winds up crashing WoW in the x64 environment. By specifically specifying x86, the x64 OS will treat the application as a pure x86 application and make sure everything runs smoothly.

Javascript which runs on the client machine can't access the local disk file system due to security restrictions.

If you want to access the client's disk file system then look into an embedded client application which you serve up from your webpage, like an Applet, Silverlight or something like that. If you like to access the server's disk file system, then look for the solution in the server side corner using a server side programming language like Java, PHP, etc, whatever your webserver is currently using/supporting.

One way to do it will be to move all the php code above the HTML, copy the result to a variable and then add the result in the <input> tag.
Try this -

<?php
//Adding the php to the top.
if(isset($_POST['submit']))
{
    $value1=$_POST['value1'];
    $value2=$_POST['value2'];
    $sign=$_POST['sign'];
    ...
        //Adding to $result variable
    if($sign=='-') {
      $result = $value1-$value2;
    }
    //Rest of your code...
}
?>
<html>
<!--Rest of your tags...-->
Result:<br><input type"text" name="result" value = "<?php echo (isset($result))?$result:'';?>">

Just to point out the generic way to iterate over any map:

 private <K, V> void iterateOverMap(Map<K, V> map) {
    for (Map.Entry<K, V> entry : map.entrySet()) {
        System.out.println("key ->" + entry.getKey() + ", value->" + entry.getValue());
    }
    }

Dir.new('/my/dir').each do |name|
  ...
end

by default <UL/> contains default padding

therefore try adding style to padding:0px in css class or inline css

1. Where does user.id go after passport.serializeUser has been called?

The user id (you provide as the second argument of the done function) is saved in the session and is later used to retrieve the whole object via the deserializeUser function.

serializeUser determines which data of the user object should be stored in the session. The result of the serializeUser method is attached to the session as req.session.passport.user = {}. Here for instance, it would be (as we provide the user id as the key) req.session.passport.user = {id: 'xyz'}

2. We are calling passport.deserializeUser right after it where does it fit in the workflow?

The first argument of deserializeUser corresponds to the key of the user object that was given to the done function (see 1.). So your whole object is retrieved with help of that key. That key here is the user id (key can be any key of the user object i.e. name,email etc). In deserializeUser that key is matched with the in memory array / database or any data resource.

The fetched object is attached to the request object as req.user

Visual Flow

passport.serializeUser(function(user, done) {
    done(null, user.id);
});              ¦
                 ¦ 
                 ¦
                 +--------------------? saved to session
                                   ¦    req.session.passport.user = {id: '..'}
                                   ¦
                                   ?           
passport.deserializeUser(function(id, done) {
                   +---------------+
                   ¦
                   ? 
    User.findById(id, function(err, user) {
        done(err, user);
    });            +--------------? user object attaches to the request as req.user   
});

ASCII was indeed originally conceived as a 7-bit code. This was done well before 8-bit bytes became ubiquitous, and even into the 1990s you could find software that assumed it could use the 8th bit of each byte of text for its own purposes ("not 8-bit clean"). Nowadays people think of it as an 8-bit coding in which bytes 0x80 through 0xFF have no defined meaning, but that's a retcon.

There are dozens of text encodings that make use of the 8th bit; they can be classified as ASCII-compatible or not, and fixed- or variable-width. ASCII-compatible means that regardless of context, single bytes with values from 0x00 through 0x7F encode the same characters that they would in ASCII. You don't want to have anything to do with a non-ASCII-compatible text encoding if you can possibly avoid it; naive programs expecting ASCII tend to misinterpret them in catastrophic, often security-breaking fashion. They are so deprecated nowadays that (for instance) HTML5 forbids their use on the public Web, with the unfortunate exception of UTF-16. I'm not going to talk about them any more.

A fixed-width encoding means what it sounds like: all characters are encoded using the same number of bytes. To be ASCII-compatible, a fixed-with encoding must encode all its characters using only one byte, so it can have no more than 256 characters. The most common such encoding nowadays is Windows-1252, an extension of ISO 8859-1.

There's only one variable-width ASCII-compatible encoding worth knowing about nowadays, but it's very important: UTF-8, which packs all of Unicode into an ASCII-compatible encoding. You really want to be using this if you can manage it.

As a final note, "ASCII" nowadays takes its practical definition from Unicode, not its original standard (ANSI X3.4-1968), because historically there were several dozen variations on the ASCII 127-character repertoire -- for instance, some of the punctuation might be replaced with accented letters to facilitate the transmission of French text. Nowadays all of those variations are obsolescent, and when people say "ASCII" they mean that the bytes with value 0x00 through 0x7F encode Unicode codepoints U+0000 through U+007F. This will probably only matter to you if you ever find yourself writing a technical standard.

If you're interested in the history of ASCII and the encodings that preceded it, start with the paper "The Evolution of Character Codes, 1874-1968" (samizdat copy at http://falsedoor.com/doc/ascii_evolution-of-character-codes.pdf) and then chase its references (many of which are not available online and may be hard to find even with access to a university library, I regret to say).

This one works for me

CREATE Function [dbo].[RemoveNumericCharacters](@Temp VarChar(1000))
Returns VarChar(1000)
AS
Begin

    Declare @NumRange as varchar(50) = '%[0-9]%'
    While PatIndex(@NumRange, @Temp) > 0
        Set @Temp = Stuff(@Temp, PatIndex(@NumRange, @Temp), 1, '')

    Return @Temp
End

and you can use it like so

SELECT dbo.[RemoveNumericCharacters](Name) FROM TARGET_TABLE

The CompileSdkVersion is the version of the SDK platform your app works with for compilation, etc DURING the development process (you should always use the latest) This is shipped with the API version you are using

You will see this in your build.gradle file:

targetSdkVersion: contains the info your app ships with AFTER the development process to the app store that allows it to TARGET the SPECIFIED version of the Android platform. Depending on the functionality of your app, it can target API versions lower than the current.For instance, you can target API 18 even if the current version is 23.

Take a good look at this official Google page.

In addition to what Andrew said, it is worth noting that:

• .NET isn't just a library, but also a runtime for executing applications.
• The knowledge of C# implies some knowledge of .NET (because the C# object model corresponds to the .NET object model and you can do something interesting in C# just by using .NET libraries). The opposite isn't necessarily true as you can use other languages to write .NET applications.

The distinction between a language, a runtime, and a library is more strict in .NET/C# than for example in C++, where the language specification also includes some basic library functions. The C# specification says only a very little about the environment (basically, that it should contain some types such as int, but that's more or less all).

1. Open Storage Management

   • Go to ? > About This Mac > Window > Storage Management
   • Or, hit ? + Space to open Spotlight and search for Storage Management.

2. Select Applications on left pane.

3. Right click on Xcode on the right pane and select delete.

This will remove XCode from the installed applications list of your Mac's App Store.

Since it is for Ganymede (eclipse 3.4), I would advise to uncompress the zip in the dropins in the HibernateTools-3.2.4.Beta1-R20081031133 directory created after the name of the archive.

Once it is done, create in the [eclipse\dropins\HibernateTools-3.2.4.Beta1-R20081031133] an 'eclipse' directory, in which you will move the plugins and features directories creating at the extraction of the files of the archive.

Add a .exclipseextension in [eclipse\dropins\HibernateTools-3.2.4.Beta1-R20081031133\eclipse]:

name=QuickRex
id=org.hibernate.eclipse
version=3.2.4b1

So:

eclipse
    dropins
         HibernateTools-3.2.4.Beta1-R20081031133
             eclipse
                 .eclipseextension
                 features
                 plugins

Relaunch eclipse and the plugin Hibernate should be detected.

If you install another eclipse, just copy the content of your dropins directory to the new eclipse\dropins and your set of plugins will be detected again.

One possible solution that I use is to use python3. It seems to solve many utf issues.

Sorry for the late answer, but it may help people in the future.

For example,

#!/usr/bin/env python3
import json
# your code follows

You Can use simply

git checkout  commithash

in this sequence

git clone `URLTORepository`
cd `into your cloned folder`
git checkout commithash

commit hash looks like this "45ef55ac20ce2389c9180658fdba35f4a663d204"

Putting the condition in the join seems "semantically wrong" to me, as that's not what JOINs are "for". But that's very qualitative.

Additional problem: if you decide to switch from an inner join to, say, a right join, having the condition be inside the JOIN could lead to unexpected results.

To avoid multiple formdata sends:

Don't forget to unbind submit event, before the form submited again, User can call sumbit function more than one time, maybe he forgot something, or was a validation error.

 $("#idForm").unbind().submit( function(e) {
  ....

Each cell in the array is treated as unsigned int:

private int unsignedIntFromByteArray(byte[] bytes) {
int res = 0;
if (bytes == null)
    return res;


for (int i=0;i<bytes.length;i++){
    res = res | ((bytes[i] & 0xff) << i*8);
}
return res;
}

You can use monitorEvents function.

Just inspect your element (right mouse click ? Inspect on visible element or go to Elements tab in Chrome Developer Tools and select wanted element) then go to Console tab and write:

monitorEvents($0)

Now when you move mouse over this element, focus or click it, the name of the fired event will be displayed with its data.

To stop getting this data just write this to console:

unmonitorEvents($0)

$0 is just the last DOM element selected by Chrome Developer Tools. You can pass any other DOM object there (for example result of getElementById or querySelector).

You can also specify event "type" as second parameter to narrow monitored events to some predefined set. For example:

monitorEvents(document.body, 'mouse')

List of this available types is here.

I made a small gif that illustrates how this feature works:

Since 2014b, Matlab has these normalization routines embedded natively in the histogram function (see the help file for the 6 routines this function offers). Here is an example using the PDF normalization (the sum of all the bins is 1).

data = 2*randn(5000,1) + 5;             % generate normal random (m=5, std=2)
h = histogram(data,'Normalization','pdf')   % PDF normalization

The corresponding PDF is

Nbins = h.NumBins;
edges = h.BinEdges; 
x = zeros(1,Nbins);
for counter=1:Nbins
    midPointShift = abs(edges(counter)-edges(counter+1))/2;
    x(counter) = edges(counter)+midPointShift;
end

mu = mean(data);
sigma = std(data);

f = exp(-(x-mu).^2./(2*sigma^2))./(sigma*sqrt(2*pi));

The two together gives

hold on;
plot(x,f,'LineWidth',1.5)

An improvement that might very well be due to the success of the actual question and accepted answer!

EDIT - The use of hist and histc is not recommended now, and histogram should be used instead. Beware that none of the 6 ways of creating bins with this new function will produce the bins hist and histc produce. There is a Matlab script to update former code to fit the way histogram is called (bin edges instead of bin centers - link). By doing so, one can compare the pdf normalization methods of @abcd (trapz and sum) and Matlab (pdf).

The 3 pdf normalization method give nearly identical results (within the range of eps).

TEST:

A = randn(10000,1);
centers = -6:0.5:6;
d = diff(centers)/2;
edges = [centers(1)-d(1), centers(1:end-1)+d, centers(end)+d(end)];
edges(2:end) = edges(2:end)+eps(edges(2:end));

figure;
subplot(2,2,1);
hist(A,centers);
title('HIST not normalized');

subplot(2,2,2);
h = histogram(A,edges);
title('HISTOGRAM not normalized');

subplot(2,2,3)
[counts, centers] = hist(A,centers); %get the count with hist
bar(centers,counts/trapz(centers,counts))
title('HIST with PDF normalization');


subplot(2,2,4)
h = histogram(A,edges,'Normalization','pdf')
title('HISTOGRAM with PDF normalization');

dx = diff(centers(1:2))
normalization_difference_trapz = abs(counts/trapz(centers,counts) - h.Values);
normalization_difference_sum = abs(counts/sum(counts*dx) - h.Values);

max(normalization_difference_trapz)
max(normalization_difference_sum)

The maximum difference between the new PDF normalization and the former one is 5.5511e-17.

dict((k, v) for k, v in points.items() if all(x < 5 for x in v))

You could choose to call .iteritems() instead of .items() if you're in Python 2 and points may have a lot of entries.

all(x < 5 for x in v) may be overkill if you know for sure each point will always be 2D only (in that case you might express the same constraint with an and) but it will work fine;-).

In the project right click

-> new -> module
-> import jar/AAR package
-> import select the jar file to import
-> click ok -> done

You can follow the screenshots below:

You will see this:

There's a package that's dedicated to this specifically:

from thesmuggler import smuggle

# À la `import weapons`
weapons = smuggle('weapons.py')

# À la `from contraband import drugs, alcohol`
drugs, alcohol = smuggle('drugs', 'alcohol', source='contraband.py')

# À la `from contraband import drugs as dope, alcohol as booze`
dope, booze = smuggle('drugs', 'alcohol', source='contraband.py')

It's tested across Python versions (Jython and PyPy too), but it might be overkill depending on the size of your project.

** for Hexa to String**

let input  = '32343630';

Note : let output = new Buffer(input, 'hex'); // this is deprecated

let buf = Buffer.from(input, "hex");
let data = buf.toString("utf8");

Hope this will help you .

Here is Html code:-

    <body>
    <div ng-controller="MyController" class="container">
      <h1>Modal example</h1>
      <button ng-click="open()" class="btn btn-primary">Test Modal</button>

      <modal title="Login form" visible="showModal">
        <form role="form">

        </form>
      </modal>
    </div>
</body>

AngularJs code:-

var mymodal = angular.module('mymodal', []);

mymodal.controller('MyController', function ($scope) {
    $scope.showModal = false;
    $scope.open = function(){
    $scope.showModal = !$scope.showModal;
    };
  });

mymodal.directive('modal', function () {
    return {
      template: '<div class="modal fade">' + 
          '<div class="modal-dialog">' + 
            '<div class="modal-content">' +

      }
    };
  });

Check this--jsfiddle

<table style="border: 5px solid black">

This only adds a border around the table.

If you want same border through CSS then add this rule:

table tr td { border: 5px solid black; }

and one thing for HTML table to avoid spaces

<table cellspacing="0" cellpadding="0">

Try this awk

awk -F, '{$0=$3}1' file
column3

• , Divide fields by ,
• $0=$3 Set the line to only field 3
• 1 Print all out. (explained here)

This could also be used:

awk -F, '{print $3}' file

You could use one of the below solutions:

$items = Item::whereIn('id', [1,2,..])->get();

or:

$items = DB::table('items')->whereIn('id',[1,2,..])->get();

If you don't want to wrap a table under any div:

table{
  table-layout: fixed;
}
tbody{
      display: block;
    overflow: auto;
}

Some more details in relation with the response from Cody Gray. As it took me some time to digest it I though it might be usefull to others.

First, some definitions:

1. There are TypeNames, which are string representations of the type of an object, interface, etc. For example, Bar is a TypeName in Public Class Bar, or in Dim Foo as Bar. TypeNames could be seen as "labels" used in the code to tell the compiler which type definition to look for in a dictionary where all available types would be described.
2. There are System.Type objects which contain a value. This value indicates a type; just like a String would take some text or an Int would take a number, except we are storing types instead of text or numbers. Type objects contain the type definitions, as well as its corresponding TypeName.

Second, the theory:

1. Foo.GetType() returns a Type object which contains the type for the variable Foo. In other words, it tells you what Foo is an instance of.
2. GetType(Bar) returns a Type object which contains the type for the TypeName Bar.

3. In some instances, the type an object has been Cast to is different from the type an object was first instantiated from. In the following example, MyObj is an Integer cast into an Object:

   Dim MyVal As Integer = 42 Dim MyObj As Object = CType(MyVal, Object)

So, is MyObj of type Object or of type Integer? MyObj.GetType() will tell you it is an Integer.

4. But here comes the Type Of Foo Is Bar feature, which allows you to ascertain a variable Foo is compatible with a TypeName Bar. Type Of MyObj Is Integer and Type Of MyObj Is Object will both return True. For most cases, TypeOf will indicate a variable is compatible with a TypeName if the variable is of that Type or a Type that derives from it. More info here: https://docs.microsoft.com/en-us/dotnet/visual-basic/language-reference/operators/typeof-operator#remarks

The test below illustrate quite well the behaviour and usage of each of the mentionned keywords and properties.

Public Sub TestMethod1()

    Dim MyValInt As Integer = 42
    Dim MyValDble As Double = CType(MyValInt, Double)
    Dim MyObj As Object = CType(MyValDble, Object)

    Debug.Print(MyValInt.GetType.ToString) 'Returns System.Int32
    Debug.Print(MyValDble.GetType.ToString) 'Returns System.Double
    Debug.Print(MyObj.GetType.ToString) 'Returns System.Double

    Debug.Print(MyValInt.GetType.GetType.ToString) 'Returns System.RuntimeType
    Debug.Print(MyValDble.GetType.GetType.ToString) 'Returns System.RuntimeType
    Debug.Print(MyObj.GetType.GetType.ToString) 'Returns System.RuntimeType

    Debug.Print(GetType(Integer).GetType.ToString) 'Returns System.RuntimeType
    Debug.Print(GetType(Double).GetType.ToString) 'Returns System.RuntimeType
    Debug.Print(GetType(Object).GetType.ToString) 'Returns System.RuntimeType

    Debug.Print(MyValInt.GetType = GetType(Integer)) '# Returns True
    Debug.Print(MyValInt.GetType = GetType(Double)) 'Returns False
    Debug.Print(MyValInt.GetType = GetType(Object)) 'Returns False

    Debug.Print(MyValDble.GetType = GetType(Integer)) 'Returns False
    Debug.Print(MyValDble.GetType = GetType(Double)) '# Returns True
    Debug.Print(MyValDble.GetType = GetType(Object)) 'Returns False

    Debug.Print(MyObj.GetType = GetType(Integer)) 'Returns False
    Debug.Print(MyObj.GetType = GetType(Double)) '# Returns True
    Debug.Print(MyObj.GetType = GetType(Object)) 'Returns False

    Debug.Print(TypeOf MyObj Is Integer) 'Returns False
    Debug.Print(TypeOf MyObj Is Double) '# Returns True
    Debug.Print(TypeOf MyObj Is Object) '# Returns True


End Sub

EDIT

You can also use Information.TypeName(Object) to get the TypeName of a given object. For example,

Dim Foo as Bar
Dim Result as String
Result = TypeName(Foo)
Debug.Print(Result) 'Will display "Bar"

In my case, I had to install the Microsoft.Owin.Host.SystemWeb package.

I was getting the same message as you did, but then noticed I couldn't even hit a breakpoint in Startup.cs which then let me to this SO thread.

Once you have IIS Express installed (the easiest way is through Microsoft Web Platform Installer), you will find the executable file in %PROGRAMFILES%\IIS Express (%PROGRAMFILES(x86)%\IIS Express on x64 architectures) and its called iisexpress.exe.

To see all the possible command-line options, just run:

iisexpress /?

and the program detailed help will show up.

If executed without parameters, all the sites defined in the configuration file and marked to run at startup will be launched. An icon in the system tray will show which sites are running.

There are a couple of useful options once you have some sites created in the configuration file (found in %USERPROFILE%\Documents\IISExpress\config\applicationhost.config): the /site and /siteId.

With the first one, you can launch a specific site by name:

iisexpress /site:SiteName

And with the latter, you can launch by specifying the ID:

iisexpress /siteId:SiteId

With this, if IISExpress is launched from the command-line, a list of all the requests made to the server will be shown, which can be quite useful when debugging.

Finally, a site can be launched by specifying the full directory path. IIS Express will create a virtual configuration file and launch the site (remember to quote the path if it contains spaces):

iisexpress /path:FullSitePath

This covers the basic IISExpress usage from the command line.

You can do something like this:

$("input").change(function() {
  var inputs = $(this).closest('form').find(':input');
  inputs.eq( inputs.index(this)+ 1 ).focus();
});

The other answers posted here may not work for you since they depend on the next input being the very next sibling element, which often isn't the case. This approach goes up to the form and searches for the next input type element.

This is simple css for Sign Mark.

ul li:after{opacity: 1;content: '\2713';right: 20px;position: absolute;font-size: 20px;font-weight: bold;}

You need to use parentheses: myList.insert([1, 2, 3]). When you leave out the parentheses, python thinks you are trying to access myList.insert at position 1, 2, 3, because that's what brackets are used for when they are right next to a variable.

Here's how to do the same with Swift;

var valueToSave = "someValue"
NSUserDefaults.standardUserDefaults().setObject(valueToSave, forKey: "preferenceName")

To get it back later;

if let savedValue = NSUserDefaults.standardUserDefaults().stringForKey("preferenceName") {
    // Do something with savedValue
}

In Swift 3.0

var valueToSave = "someValue"
UserDefaults.standard.set(valueToSave, forKey: "preferenceName")

if let savedValue = UserDefaults.standard.string(forKey: "preferenceName") {

}

I don't think that you really want an iframe, do you?

Unless you're doing something weird, you should be getting your results back as JSON or (in the worst case) XML, right?

For your white box / extra space issue, try

instead of

According to PHPMailer Manual, full answer would be :

$mail->AddEmbeddedImage(filename, cid, name);
//Example
$mail->AddEmbeddedImage('my-photo.jpg', 'my-photo', 'my-photo.jpg '); 

Use Case :

$mail->AddEmbeddedImage("rocks.png", "my-attach", "rocks.png");
$mail->Body = 'Embedded Image: <img alt="PHPMailer" src="cid:my-attach"> Here is an image!';

If you want to display an image with a remote URL :

$mail->addStringAttachment(file_get_contents("url"), "filename");

"Upstream" would refer to the main repo that other people will be pulling from, e.g. your GitHub repo. The -u option automatically sets that upstream for you, linking your repo to a central one. That way, in the future, Git "knows" where you want to push to and where you want to pull from, so you can use git pull or git push without arguments. A little bit down, this article explains and demonstrates this concept.

The official docker answer to Run multiple services in a container.

It explains how you can do it with an init system (systemd, sysvinit, upstart) , a script (CMD ./my_wrapper_script.sh) or a supervisor like supervisord.

The && workaround can work only for services that starts in background (daemons) or that will execute quickly without interaction and release the prompt. Doing this with an interactive service (that keeps the prompt) and only the first service will start.

Add Following Code

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
    case R.id.new_item:
        Intent i = new Intent(this,SecondActivity.class);
            this.startActivity(i);
            return true;
    default:
        return super.onOptionsItemSelected(item);
    }
}

Leave your email.php code the same, but replace this JavaScript code:

 var name = $("#form_name").val();
        var email = $("#form_email").val();
        var text = $("#msg_text").val();
        var dataString = 'name='+ name + '&email=' + email + '&text=' + text;

        $.ajax({
            type: "POST",
            url: "email.php",
            data: dataString,
            success: function(){
            $('.success').fadeIn(1000);
            }
        });

with this:

    $.ajax({
        type: "POST",
        url: "email.php",
        data: $(form).serialize(),
        success: function(){
        $('.success').fadeIn(1000);
        }
    });

So that your form input names match up.

This worked for me on UTC Timestamp (2020-08-19T09:12:57.945888)

for di, i in enumerate(df['YourColumnName']):
    df['YourColumnName'][di] = pd.Timestamp(i)

List<T> equality does not check them element-by-element. You can use LINQ's SequenceEqual method for that:

var a = ints1.SequenceEqual(ints2);

To ignore order, use SetEquals:

var a = new HashSet<int>(ints1).SetEquals(ints2);

This should work, because you are comparing sequences of IDs, which do not contain duplicates. If it does, and you need to take duplicates into account, the way to do it in linear time is to compose a hash-based dictionary of counts, add one for each element of the first sequence, subtract one for each element of the second sequence, and check if the resultant counts are all zeros:

var counts = ints1
    .GroupBy(v => v)
    .ToDictionary(g => g.Key, g => g.Count());
var ok = true;
foreach (var n in ints2) {
    int c;
    if (counts.TryGetValue(n, out c)) {
        counts[n] = c-1;
    } else {
        ok = false;
        break;
    }
}
var res = ok && counts.Values.All(c => c == 0);

Finally, if you are fine with an O(N*LogN) solution, you can sort the two sequences, and compare them for equality using SequenceEqual.

I think you can use keydown too:

$('#fieldID').on('keydown', function (e) {
  //console.log(e.which);
  if (e.which === 8) {
    //do something when pressing delete
    return true;
  } else {
    //do something else
    return false;
  }
});
