It seems to me that everyone answering this question is kind-of missing the one critical issue, except @deceze -- use the right tool for the job. You can force a relational database to store almost any type of data and you can force Mongo to handle relational data, but at what cost? You end up introducing complexity at all levels of development and maintenance, from schema design to application code; not to mention the performance hit.

In 2014 we have access to many database servers that handle specific types of data exceptionally well.

• Mongo (document storage)
• Redis (key-value data storage)
• MySQL/Maria/PostgreSQL/Oracle/etc (relational data)
• CouchDB (JSON)

I'm sure I missed some others, like RabbirMQ and Cassandra. My point is, use the right tool for the data you need to store.

If your application requires storage and retrieval of a variety of data really, really fast, (and who doesn't) don't shy away from using multiple data sources for an application. Most popular web frameworks provide support for multiple data sources (Rails, Django, Grails, Cake, Zend, etc). This strategy limits the complexity to one specific area of the application, the ORM or the application's data source interface.

No. We cannot alter the constraint, only thing we can do is drop and recreate it

ALTER TABLE [TABLENAME] DROP CONSTRAINT [CONSTRAINTNAME]

Foreign Key Constraint

Alter Table Table1 Add Constraint [CONSTRAINTNAME] Foreign Key (Column) References Table2 (Column) On Update Cascade On Delete Cascade

Primary Key constraint

Alter Table Table add constraint [Primary Key] Primary key(Column1,Column2,.....)

I've started using LinqPad. In addition to being more lightweight than SSMS, you can also practice writing LINQ queries- way more fun than boring old TSQL!

You can use this ShellLink.cs class to create the shortcut.

To get the desktop directory, use:

var dir = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory);

or use Environment.SpecialFolder.CommonDesktopDirectory to create it for all users.

Your SVN passwords in Ubuntu (12.04) are in:

~/.subversion/auth/svn.simple/

However in newer versions they are encrypted, as earlier someone mentioned. To find gnome-keyring passwords, I suggest You to use 'gkeyring' program.

To install it on Ubuntu – add repository :

sudo add-apt-repository ppa:kampka/ppa
sudo apt-get update

Install it:

sudo apt-get install gkeyring

And run as following:

gkeyring --id 15 --output=name,secret

Try different key ids to find pair matching what you are looking for. Thanks to kampka for the soft.

check this, its guaranteed and easy !

• add "readonly" attribute to the input field whenever you don't want the keyboard to show

 $("#inputField").attr("readonly","readonly");

• reset when clicking it

     $("#inputField").click(function () {
              $(this).removeAttr("readonly");
              $(this).focus();  
      });

As others has answer, the Request.Files is an HttpFileCollection that contains all the files that were posted, you only need to ask that object for the file like this:

Request.Files["myFile"]

But what happen when there are more than one input mark-up with the same attribute name:

Select file 1 <input type="file" name="myFiles" />
Select file 2 <input type="file" name="myFiles" />

On the server side the previous code Request.Files["myFile"] only return one HttpPostedFile object instead of the two files. I have seen on .net 4.5 an extension method called GetMultiple but for prevoious versions it doesn't exists, for that matter i propose the extension method as:

public static IEnumerable<HttpPostedFile> GetMultiple(this HttpFileCollection pCollection, string pName)
{
        for (int i = 0; i < pCollection.Count; i++)
        {
            if (pCollection.GetKey(i).Equals(pName))
            {
                yield return pCollection.Get(i);
            }
        }
}

This extension method will return all the HttpPostedFile objects that have the name "myFiles" in the HttpFileCollection if any exists.

Here's a method which is similar to Kelly's but will remove any pre-existing script with the same source, and uses jQuery.

<script>
    function reload_js(src) {
        $('script[src="' + src + '"]').remove();
        $('<script>').attr('src', src).appendTo('head');
    }
    reload_js('source_file.js');
</script>

Note that the 'type' attribute is no longer needed for scripts as of HTML5. (http://www.w3.org/html/wg/drafts/html/master/scripting-1.html#the-script-element)

The problem (as KennyTM noted) is that LaTeX won't hyphenate words with dashes in them. Luckily, there's a standard package (part of ncctools) that addresses that very problem, called extdash. This defines new hyphen and dash commands that do not disrupt hyphenation, and which can allow or prevent line breaks at the hyphen/dash. I prefer to use it with the shortcuts option, so I can use, e.g., \-/ rather than \Hyphdash. Here's what you want:

\usepackage[shortcuts]{extdash} ... multi\-/disciplinary

To prevent breaking at that hyphen, use multi\=/disciplinary

(Aside: The Chicago Manual of Style advises dropping the hyphens attaching affixes like 'multi', unless the word is ambiguous or unintelligible without it.)

Check The port 1521 in your server. May be its blocked by firewall. Or disable firewall and try.

A simpler version of your code would be:

dict(zip(names, d.values()))

If you want to keep the same structure, you can change it to:

vlst = list(d.values())
{names[i]: vlst[i] for i in range(len(names))}

(You can just as easily put list(d.values()) inside the comprehension instead of vlst; it's just wasteful to do so since it would be re-generating the list every time).

As an aside, it is always a good practice (and possibly a solution for this type of issue) to delete a large number of rows by using batches:

WHILE EXISTS (SELECT 1 
              FROM   YourTable 
              WHERE  <yourCondition>) 
  DELETE TOP(10000) FROM YourTable 
  WHERE  <yourCondition>

You can use a function like strtol() which will convert a character array to a long.

It has a parameter which is a way to detect the first character that didn't convert properly. If this is anything other than the end of the string, then you have a problem.

See the following program for an example:

#include <stdio.h>
#include <stdlib.h>

int main( int argc, char *argv[]) {
    int i;
    long val;
    char *next;

    // Process each argument given.

    for (i = 1; i < argc; i++) {
        // Get value with failure detection.

        val = strtol (argv[i], &next, 10);

        // Check for empty string and characters left after conversion.

        if ((next == argv[i]) || (*next != '\0')) {
            printf ("'%s' is not valid\n", argv[i]);
        } else {
            printf ("'%s' gives %ld\n", argv[i], val);
        }
    }

    return 0;
}

Running this, you can see it in operation:

pax> testprog hello "" 42 12.2 77x

'hello' is not valid
'' is not valid
'42' gives 42
'12.2' is not valid
'77x' is not valid

Using regexes with "\s" and doing simple string.split()'s will also remove other whitespace - like newlines, carriage returns, tabs. Unless this is desired, to only do multiple spaces, I present these examples.

I used 11 paragraphs, 1000 words, 6665 bytes of Lorem Ipsum to get realistic time tests and used random-length extra spaces throughout:

original_string = ''.join(word + (' ' * random.randint(1, 10)) for word in lorem_ipsum.split(' '))

The one-liner will essentially do a strip of any leading/trailing spaces, and it preserves a leading/trailing space (but only ONE ;-).

# setup = '''

import re

def while_replace(string):
    while '  ' in string:
        string = string.replace('  ', ' ')

    return string

def re_replace(string):
    return re.sub(r' {2,}' , ' ', string)

def proper_join(string):
    split_string = string.split(' ')

    # To account for leading/trailing spaces that would simply be removed
    beg = ' ' if not split_string[ 0] else ''
    end = ' ' if not split_string[-1] else ''

    # versus simply ' '.join(item for item in string.split(' ') if item)
    return beg + ' '.join(item for item in split_string if item) + end

original_string = """Lorem    ipsum        ... no, really, it kept going...          malesuada enim feugiat.         Integer imperdiet    erat."""

assert while_replace(original_string) == re_replace(original_string) == proper_join(original_string)

#'''

# while_replace_test
new_string = original_string[:]

new_string = while_replace(new_string)

assert new_string != original_string

# re_replace_test
new_string = original_string[:]

new_string = re_replace(new_string)

assert new_string != original_string

# proper_join_test
new_string = original_string[:]

new_string = proper_join(new_string)

assert new_string != original_string

NOTE: The "while version" made a copy of the original_string, as I believe once modified on the first run, successive runs would be faster (if only by a bit). As this adds time, I added this string copy to the other two so that the times showed the difference only in the logic. Keep in mind that the main stmt on timeit instances will only be executed once; the original way I did this, the while loop worked on the same label, original_string, thus the second run, there would be nothing to do. The way it's set up now, calling a function, using two different labels, that isn't a problem. I've added assert statements to all the workers to verify we change something every iteration (for those who may be dubious). E.g., change to this and it breaks:

# while_replace_test
new_string = original_string[:]

new_string = while_replace(new_string)

assert new_string != original_string # will break the 2nd iteration

while '  ' in original_string:
    original_string = original_string.replace('  ', ' ')

Tests run on a laptop with an i5 processor running Windows 7 (64-bit).

timeit.Timer(stmt = test, setup = setup).repeat(7, 1000)

For the trivial string, it would seem that a while-loop is the fastest, followed by the Pythonic string-split/join, and regex pulling up the rear.

For non-trivial strings, seems there's a bit more to consider. 32-bit 2.7? It's regex to the rescue! 2.7 64-bit? A while loop is best, by a decent margin. 32-bit 3.2, go with the "proper" join. 64-bit 3.3, go for a while loop. Again.

In the end, one can improve performance if/where/when needed, but it's always best to remember the mantra:

1. Make It Work
2. Make It Right
3. Make It Fast

IANAL, YMMV, Caveat Emptor!

I had this happen to me after an update to a new Xcode. Running

xcode-select --install

fixed it for me.

More generally, you can also convert the new data into an array and use something like concat:

var newData = this.state.data.concat([data]);  
this.setState({data: newData})

This pattern is actually used in Facebook's ToDo demo app (see the section "An Application") at https://facebook.github.io/react/.

After seeing this post I found a useful link:

Here is a stencil example.

We are already in 21st century!! Don't try to implement the already existing data structures. Try to use the existing data structures.

Use STL or Boost library

I hate additional functions so... here is an awesome vue solution without an additional vue methods, only var

1. create html element, set controls and directive

    <p @click="popup = !popup" v-out="popup">

    <div v-if="popup">
       My awesome popup
    </div>

2. create a var in data like

data:{
   popup: false,
}

3. add vue directive. its

Vue.directive('out', {

    bind: function (el, binding, vNode) {
        const handler = (e) => {
            if (!el.contains(e.target) && el !== e.target) {
                //and here is you toggle var. thats it
                vNode.context[binding.expression] = false
            }
        }
        el.out = handler
        document.addEventListener('click', handler)
    },

    unbind: function (el, binding) {
        document.removeEventListener('click', el.out)
        el.out = null
    }
})

From the C++ FAQ Lite:

The members and base classes of a struct are public by default, while in class, they default to private. Note: you should make your base classes explicitly public, private, or protected, rather than relying on the defaults.

struct and class are otherwise functionally equivalent.

OK, enough of that squeaky clean techno talk. Emotionally, most developers make a strong distinction between a class and a struct. A struct simply feels like an open pile of bits with very little in the way of encapsulation or functionality. A class feels like a living and responsible member of society with intelligent services, a strong encapsulation barrier, and a well defined interface. Since that's the connotation most people already have, you should probably use the struct keyword if you have a class that has very few methods and has public data (such things do exist in well designed systems!), but otherwise you should probably use the class keyword.

nil means absence of value while NULL represent No Object,

NSArray *array = @[@"Hello World !", @101,[NSNULL null] ];

Here [NSNULL null] is an object which means no object, at the same time you cannot add nil to indicate absence of object.

you can use both nil and [NSNUll null] for checking too.

This was driving me crazy, but it seems that aularon's edit was missing the colon after "Vary". So changing "Vary Accept-Encoding" to "Vary: Accept-Encoding" fixed the issue for me.

I would have commented below the post, but it doesn't seem like it will let me.

Anyhow, I hope this saves someone the same trouble I was having.

If you would like to filter out duplicate values from an array on a known unique object property, you could use the following snippet:

let arr = [
  { "name": "Joe", "age": 17 },
  { "name": "Bob", "age": 17 },
  { "name": "Carl", "age": 35 },
  { "name": "Carl", "age": 35 }
];

let uniqueValues = [...arr.reduce((map, val) => {
    if (!map.has(val.name)) {
        map.set(val.name, val);
    }
    return map;
}, new Map()).values()]

Make sure that you have write permissions for that directory you were trying to create file by properties

You can add attributes to a function, and use it as a static variable.

def myfunc():
  myfunc.counter += 1
  print myfunc.counter

# attribute must be initialized
myfunc.counter = 0

Alternatively, if you don't want to setup the variable outside the function, you can use hasattr() to avoid an AttributeError exception:

def myfunc():
  if not hasattr(myfunc, "counter"):
     myfunc.counter = 0  # it doesn't exist yet, so initialize it
  myfunc.counter += 1

Anyway static variables are rather rare, and you should find a better place for this variable, most likely inside a class.

Override the onsubmit action of the form to be a call to your function and add return false after it, ie:

<form onsubmit="javascript:myfunc();return false;" >

You may consider 3rd party tool that called Excel Jetcell .NET component for read/write excel files:

C# sample

// Create New Excel Workbook
ExcelWorkbook Wbook = new ExcelWorkbook();
ExcelCellCollection Cells = Wbook.Worksheets.Add("Sheet1").Cells;

Cells["A1"].Value = "Excel writer example (C#)";
Cells["A1"].Style.Font.Bold = true;
Cells["B1"].Value = "=550 + 5";

// Write Excel XLS file
Wbook.WriteXLS("excel_net.xls");

VB.NET sample

' Create New Excel Workbook
Dim Wbook As ExcelWorkbook = New ExcelWorkbook()
Dim Cells As ExcelCellCollection = Wbook.Worksheets.Add("Sheet1").Cells

Cells("A1").Value = "Excel writer example (C#)"
Cells("A1").Style.Font.Bold = True
Cells("B1").Value = "=550 + 5"

' Write Excel XLS file
Wbook.WriteXLS("excel_net.xls")

range step should be -1

   for k in range(10,0,-1):
      print k

Additionally to setting the LINESIZE, as LordScree suggested, you could also specify to output to a file, to overcome the problem with the console width. Here's how I do it:

set linesize 15000;
spool myoutput.txt;
SELECT 
...
spool off;

Override the default input onChange behavior (call the function only when control loss focus and value was change)

NOTE: ngChange is not similar to the classic onChange event it firing the event while the value is changing This directive stores the value of the element when it gets the focus
On blurs it checks whether the new value has changed and if so it fires the event

@param {String} - function name to be invoke when the "onChange" should be fired

@example < input my-on-change="myFunc" ng-model="model">

angular.module('app', []).directive('myOnChange', function () { 
    return {
        restrict: 'A',
        require: 'ngModel',
        scope: {
            myOnChange: '='
        },
        link: function (scope, elm, attr) {
            if (attr.type === 'radio' || attr.type === 'checkbox') {
                return;
            }
            // store value when get focus
            elm.bind('focus', function () {
                scope.value = elm.val();

            });

            // execute the event when loose focus and value was change
            elm.bind('blur', function () {
                var currentValue = elm.val();
                if (scope.value !== currentValue) {
                    if (scope.myOnChange) {
                        scope.myOnChange();
                    }
                }
            });
        }
    };
});

Try this

Dim app As Excel.Application = Nothing
Dim Active_Cell As Excel.Range = Nothing

Try
            app = CType(Marshal.GetActiveObject("Excel.Application"), Excel.Application)
 Active_Cell = app.ActiveCell

Catch ex As Exception
            MsgBox(ex.Message)
            Exit Sub
        End Try

'             .address will return the cell reference :)

For Express 4.0 I found that using application level variables works a little differently & Cory's answer did not work for me.

From the docs: http://expressjs.com/en/api.html#app.locals

I found that you could declare a global variable for the app in

app.locals

e.g

app.locals.baseUrl = "http://www.google.com"

And then in your application you can access these variables & in your express middleware you can access them in the req object as

req.app.locals.baseUrl

e.g.

console.log(req.app.locals.baseUrl)
//prints out http://www.google.com

In Package Manager Console

Install-Package Microsoft.AspNet.WebApi.Core -version 5.2.3

                alert("Data was succesfully captured");
            },
        });

Very useful. I modified it to copy a JavaScript variable value to clipboard:

function copyToClipboard(val){
    var dummy = document.createElement("input");
    dummy.style.display = 'none';
    document.body.appendChild(dummy);

    dummy.setAttribute("id", "dummy_id");
    document.getElementById("dummy_id").value=val;
    dummy.select();
    document.execCommand("copy");
    document.body.removeChild(dummy);
}

http://localhost:8080/web: localhost ( hostname ) is the machine name or IP address of the host server e.g Glassfish, Tomcat. 8080 ( port ) is the address of the port on which the host server is listening for requests.

http://localhost/web: localhost ( hostname ) is the machine name or IP address of the host server e.g Glassfish, Tomcat. host server listening to default port 80.

The second form will be ignored, see the snippet from WebKit for example:

bool HTMLParser::formCreateErrorCheck(Token* t, RefPtr<Node>& result)
{
    // Only create a new form if we're not already inside one.
    // This is consistent with other browsers' behavior.
    if (!m_currentFormElement) {
        m_currentFormElement = new HTMLFormElement(formTag, m_document);
        result = m_currentFormElement;
        pCloserCreateErrorCheck(t, result);
    }
    return false;
}

The error seem to appear when u have more than one reference of the same file. I had 2 files of the same name and got this error. When I delete one of them the error disappear..

Its not possible as you are expecting. But you can do something like this. Pass the your java script value to the servlet/controller, do your processing and then pass this value to the jsp page by putting it into some object's as your requirement. Then you can use this value as you want.

I also got the same problem. And what I simple did is just adding const char* instead of char*. And the problem solved. As others have mentioned above it is a compatible error. C treats strings as char arrays while C++ treat them as const char arrays.

Simplest answer:

function isSafari() {
 if (navigator.vendor.match(/[Aa]+pple/g).length > 0 ) 
   return true; 
 return false;
}

This simple solution posted here Force page refresh on back button worked ...

I've tried to force a page to be downloaded again by browser when user clicks back button, but nothing worked. I appears that modern browsers have separate cache for pages, which stores complete state of a page (including JavaScript generated DOM elements), so when users presses back button, previous page is shown instantly in state the user has left it. If you want to force browser to reload page on back button, add onunload="" to your (X)HTML body element:

<body onunload="">

This disables special cache and forces page reload when user presses back button. Think twice before you use it. Fact of needing such solution is a hint your site navigation concept is flawed.

In C arrays, arr[3] and 3[arr] are the same, and their equivalent pointer notations are *(arr + 3) to *(3 + arr). But on the contrary [arr]3 or [3]arr is not correct and will result into syntax error, as (arr + 3)* and (3 + arr)* are not valid expressions. The reason is dereference operator should be placed before the address yielded by the expression, not after the address.

The simpliest way to wrap a function

    func(*args, **kwargs)

... is to manually write a wrapper that would call func() inside itself:

    def wrapper(*args, **kwargs):
        # do something before
        try:
            return func(*a, **kwargs)
        finally:
            # do something after

In Python function is an object, so you can pass it's name as an argument of another function and return it. You can also write a wrapper generator for any function anyFunc():

    def wrapperGenerator(anyFunc, *args, **kwargs):
        def wrapper(*args, **kwargs):
            try:
                # do something before
                return anyFunc(*args, **kwargs)
            finally:
                #do something after
        return wrapper

Please also note that in Python when you don't know or don't want to name all the arguments of a function, you can refer to a tuple of arguments, which is denoted by its name, preceded by an asterisk in the parentheses after the function name:

    *args

For example you can define a function that would take any number of arguments:

    def testFunc(*args):
        print args    # prints the tuple of arguments

Python provides for even further manipulation on function arguments. You can allow a function to take keyword arguments. Within the function body the keyword arguments are held in a dictionary. In the parentheses after the function name this dictionary is denoted by two asterisks followed by the name of the dictionary:

    **kwargs

A similar example that prints the keyword arguments dictionary:

    def testFunc(**kwargs):
        print kwargs    # prints the dictionary of keyword arguments

This is a good solution to many problems:

function datetotime ($date, $format = 'YYYY-MM-DD') {

    if ($format == 'YYYY-MM-DD') list($year, $month, $day) = explode('-', $date);
    if ($format == 'YYYY/MM/DD') list($year, $month, $day) = explode('/', $date);
    if ($format == 'YYYY.MM.DD') list($year, $month, $day) = explode('.', $date);

    if ($format == 'DD-MM-YYYY') list($day, $month, $year) = explode('-', $date);
    if ($format == 'DD/MM/YYYY') list($day, $month, $year) = explode('/', $date);
    if ($format == 'DD.MM.YYYY') list($day, $month, $year) = explode('.', $date);

    if ($format == 'MM-DD-YYYY') list($month, $day, $year) = explode('-', $date);
    if ($format == 'MM/DD/YYYY') list($month, $day, $year) = explode('/', $date);
    if ($format == 'MM.DD.YYYY') list($month, $day, $year) = explode('.', $date);

    return mktime(0, 0, 0, $month, $day, $year);

}

It is good programming practice to return an empty array [] if the expected return type is an array. This makes sure that the receiver of the json can treat the value as an array immediately without having to first check for null. It's the same way with empty objects using open-closed braces {}.

Strings, Booleans and integers do not have an 'empty' form, so there it is okay to use null values.

This is also addressed in Joshua Blochs excellent book "Effective Java". There he describes some very good generic programming practices (often applicable to other programming langages as well). Returning empty collections instead of nulls is one of them.

Here's a link to that part of his book:

http://jtechies.blogspot.nl/2012/07/item-43-return-empty-arrays-or.html

Handling Commas

For handling commas inside of values when using string.Format(...), the following has worked for me:

var newLine = string.Format("\"{0}\",\"{1}\",\"{2}\"",
                              first,
                              second,
                              third                                    
                              );
csv.AppendLine(newLine);

So to combine it with Johan's answer, it'd look like this:

//before your loop
var csv = new StringBuilder();

//in your loop
  var first = reader[0].ToString();
  var second = image.ToString();
  //Suggestion made by KyleMit
  var newLine = string.Format("\"{0}\",\"{1}\"", first, second);
  csv.AppendLine(newLine);  

//after your loop
File.WriteAllText(filePath, csv.ToString());

Returning CSV File

If you simply wanted to return the file instead of writing it to a location, this is an example of how I accomplished it:

From a Stored Procedure

public FileContentResults DownloadCSV()
{
  // I have a stored procedure that queries the information I need
  SqlConnection thisConnection = new SqlConnection("Data Source=sv12sql;User ID=UI_Readonly;Password=SuperSecure;Initial Catalog=DB_Name;Integrated Security=false");
  SqlCommand queryCommand = new SqlCommand("spc_GetInfoINeed", thisConnection);
  queryCommand.CommandType = CommandType.StoredProcedure;

  StringBuilder sbRtn = new StringBuilder();

  // If you want headers for your file
  var header = string.Format("\"{0}\",\"{1}\",\"{2}\"",
                             "Name",
                             "Address",
                             "Phone Number"
                            );
  sbRtn.AppendLine(header);

  // Open Database Connection
  thisConnection.Open();
  using (SqlDataReader rdr = queryCommand.ExecuteReader())
  {
    while (rdr.Read())
    {
      // rdr["COLUMN NAME"].ToString();
      var queryResults = string.Format("\"{0}\",\"{1}\",\"{2}\"",
                                        rdr["Name"].ToString(),
                                        rdr["Address"}.ToString(),
                                        rdr["Phone Number"].ToString()
                                       );
      sbRtn.AppendLine(queryResults);
    }
  }
  thisConnection.Close();

  return File(new System.Text.UTF8Encoding().GetBytes(sbRtn.ToString()), "text/csv", "FileName.csv");
}

From a List

/* To help illustrate */
public static List<Person> list = new List<Person>();

/* To help illustrate */
public class Person
{
  public string name;
  public string address;
  public string phoneNumber;
}

/* The important part */
public FileContentResults DownloadCSV()
{
  StringBuilder sbRtn = new StringBuilder();

  // If you want headers for your file
  var header = string.Format("\"{0}\",\"{1}\",\"{2}\"",
                             "Name",
                             "Address",
                             "Phone Number"
                            );
  sbRtn.AppendLine(header);

  foreach (var item in list)
  {
      var listResults = string.Format("\"{0}\",\"{1}\",\"{2}\"",
                                        item.name,
                                        item.address,
                                        item.phoneNumber
                                       );
      sbRtn.AppendLine(listResults);
    }
  }

  return File(new System.Text.UTF8Encoding().GetBytes(sbRtn.ToString()), "text/csv", "FileName.csv");
}

Hopefully this is helpful.

I was getting the same issue with a different application,

Faulting application name: javaw.exe, version: 8.0.51.16, time stamp: 0x55763d32
Faulting module name: mscorwks.dll, version: 2.0.50727.5485, time stamp: 0x53a11d6c
Exception code: 0xc0000005
Fault offset: 0x0000000000501090
Faulting process id: 0x2960
Faulting application start time: 0x01d0c39a93c695f2
Faulting application path: C:\Program Files\Java\jre1.8.0_51\bin\javaw.exe
Faulting module path:C:\Windows\Microsoft.NET\Framework64\v2.0.50727\mscorwks.dll

I was using the The Enhanced Mitigation Experience Toolkit (EMET) from Microsoft and I found by disabling the EMET features on javaw.exe in my case as this was the faulting application, it enabled my application to run successfully. Make sure you don't have any similar software with security protections on memory.

// you need to have a list of data that you want the spinner to display
List<String> spinnerArray =  new ArrayList<String>();
spinnerArray.add("item1");
spinnerArray.add("item2");

ArrayAdapter<String> adapter = new ArrayAdapter<String>(
    this, android.R.layout.simple_spinner_item, spinnerArray);

adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
Spinner sItems = (Spinner) findViewById(R.id.spinner1);
sItems.setAdapter(adapter);

also to find out what is selected you could do something like this

String selected = sItems.getSelectedItem().toString();
if (selected.equals("what ever the option was")) {
}

I finally found out how to do this! Basically you need to run adb shell first and then while you're in the shell run su, which will switch the shell to run as root!

$: adb shell
$: su

The one problem I still have is that sqlite3 is not installed so the command is not recognized.

Whatever you do to secure your secret keys is not going to be a real solution. If developer can decompile the application there is no way to secure the key, hiding the key is just security by obscurity and so is code obfuscation. Problem with securing a secret key is that in order to secure it you have to use another key and that key needs to also be secured. Think of a key hidden in a box that is locked with a key. You place a box inside a room and lock the room. You are left with another key to secure. And that key is still going to be hardcoded inside your application.

So unless the user enters a PIN or a phrase there is no way to hide the key. But to do that you would have to have a scheme for managing PINs happening out of band, which means through a different channel. Certainly not practical for securing keys for services like Google APIs.

For anyone experiencing this on windows after an update

What happened was that Windows Defender made some changes. Possibly cause running data extraction scripts, but python.exe got reduced to 0kb for that project. Copying the python.exe from another project and replacing it solved for now.

A jar is merely a container. It is a file archive a la tar. While a jar may have interesting information contained within it's META-INF hierarchy, it has no obligation to specify the vintage of the classes within it's contents. For that, one must examine the class files therein.

As as Peter Lawrey mentioned in comment to the original question, you can't necessarily know which JDK release built a given class file, but you can find out the byte code class version of the class file contained in a jar.

Yes, this kinda sucks, but the first step is to extract one or more classes from the jar. For example:

$ jar xf log4j-1.2.15.jar

On Linux, Mac OS X or Windows with Cygwin installed, the file(1) command knows the class version.

$ file ./org/apache/log4j/Appender.class
./org/apache/log4j/Appender.class: compiled Java class data, version 45.3

Or alternatively, using javap from the JDK as @jikes.thunderbolt aptly points out:

$ javap -v ./org/apache/log4j/Appender.class | grep major
 major version: 45

For Windows environments without either file or grep

> javap -v ./org/apache/log4j/Appender.class | findstr major
 major version: 45

FWIW, I will concur that javap will tell a whole lot more about a given class file than the original question asked.

Anyway, a different class version, for example:

$ file ~/bin/classes/P.class
/home/dave/bin/classes/P.class: compiled Java class data, version 50.0

The class version major number corresponds to the following Java JDK versions:

• 45.3 = Java 1.1
• 46 = Java 1.2
• 47 = Java 1.3
• 48 = Java 1.4
• 49 = Java 5
• 50 = Java 6
• 51 = Java 7
• 52 = Java 8
• 53 = Java 9
• 54 = Java 10
• 55 = Java 11
• 56 = Java 12
• 57 = Java 13
• 58 = Java 14

Additionally to being iterable in a well-defined order, and the ability to use arbitrary values as keys (except -0), maps can be useful because of the following reasons:

• The spec enforces map operations to be sublinear on average.

  Any non-stupid implementation of object will use a hash table or similar, so property lookups will probably be constant on average. Then objects could be even faster than maps. But that is not required by the spec.

• Objects can have nasty unexpected behaviors.

  For example, let's say you didn't set any foo property to a newly created object obj, so you expect obj.foo to return undefined. But foo could be built-in property inherited from Object.prototype. Or you attempt to create obj.foo by using an assignment, but some setter in Object.prototype runs instead of storing your value.

  Maps prevent these kind of things. Well, unless some script messes up with Map.prototype. And Object.create(null) would work too, but then you lose the simple object initializer syntax.

A little late but I believe some further clarification is given below.

You can iterate through a JSON array with a simple loop as well, like:

for(var i = 0; i < jsonArray.length; i++)
{
    console.log(jsonArray[i].attributename);
}

If you have a JSON object and you want to loop through all of its inner objects, then you first need to get all the keys in an array and loop through the keys to retrieve objects using the key names, like:

var keys = Object.keys(jsonObject);
for(var i = 0; i < keys.length; i++) 
{
    var key = keys[i];
    console.log(jsonObject.key.attributename);
}

Single-dimensional arrays

For converting single-dimension arrays, you can cast using (array) or there's get_object_vars, which Benoit mentioned in his answer.

// Cast to an array
$array = (array) $object;

// get_object_vars
$array = get_object_vars($object);

They work slightly different from each other. For example, get_object_vars will return an array with only publicly accessible properties unless it is called from within the scope of the object you're passing (ie in a member function of the object). (array), on the other hand, will cast to an array with all public, private and protected members intact on the array, though all public now, of course.

Multi-dimensional arrays

A somewhat dirty method is to use PHP >= 5.2's native JSON functions to encode to JSON and then decode back to an array. This will not include private and protected members, however, and is not suitable for objects that contain data that cannot be JSON encoded (such as binary data).

// The second parameter of json_decode forces parsing into an associative array
$array = json_decode(json_encode($object), true);

Alternatively, the following function will convert from an object to an array including private and protected members, taken from here and modified to use casting:

function objectToArray ($object) {
    if(!is_object($object) && !is_array($object))
        return $object;

    return array_map('objectToArray', (array) $object);
}

I have a Windows 7 desktop with a Google Nexus 7 connected to that. I also had the 'offline' problem. Mine is resolved by revoking any previous authorization on Nexus. So now I get the prompt to authorize on Nexus--I am not saving the authorization for now at least--and I allow the authorization--and voila!--Android SDK correctly shows the device as 'asus-nexus_7-xxxx'.

Do this:

date('Y-m-d', strtotime('dd/mm/yyyy'));

But make sure 'dd/mm/yyyy' is the actual date.

You link to a local file the same way you link to local images. Here is an example to link to file start_caQtDM_7id.sh in the same directory as the markdown source:

I took a stab at creating a generic copy/clone service that retains types for nested objects. Would love feedback if i'm doing something wrong, but it seems to work so far...

import { Injectable } from '@angular/core';

@Injectable()
export class CopyService {

  public deepCopy<T>(objectToClone: T): T {
    // If it's a simple type or null, just return it.
    if (typeof objectToClone === 'string' ||
      typeof objectToClone === 'number' ||
      typeof objectToClone === 'undefined' ||
      typeof objectToClone === 'symbol' ||
      typeof objectToClone === 'function' ||
      typeof objectToClone === 'boolean' ||
      objectToClone === null
    ) {
      return objectToClone;
    }

    // Otherwise, check if it has a constructor we can use to properly instantiate it...
    let ctor = Object.getPrototypeOf(objectToClone).constructor;
    if (ctor) {
      let clone = new ctor();

      // Once we've instantiated the correct type, assign the child properties with deep copies of the values
      Object.keys(objectToClone).forEach(key => {
        if (Array.isArray(objectToClone[key]))
          clone[key] = objectToClone[key].map(item => this.deepCopy(item));
        else
          clone[key] = this.deepCopy(objectToClone[key]);
      });

      if (JSON.stringify(objectToClone) !== JSON.stringify(clone))
        console.warn('object cloned, but doesnt match exactly...\nobject: ' + JSON.stringify(objectToClone) + "\nclone: " + JSON.stringify(clone))

      // return our cloned object...
      return clone;
    }
    else {
      //not sure this will ever get hit, but figured I'd have a catch call.
      console.log('deep copy found something it didnt know: ' + JSON.stringify(objectToClone));
      return objectToClone;
    }
  }
}

The second thing to learn (one would argue that this should be the first) is the command line interface of your OS and compiler/linker flags and switches.

jQuery's :selected selector is probably what you are looking for.

In my case, I got a huge performance advantage by disabling Rainbow (it's a plugin that is used to color brackets in the code):

Tools -> Options -> Miscellaneous -> Rainbow (uncheck enabled)

Tested on Netbeans 10 with Java 8.

The problem of serious slowdowns occurred exclusively with particularly large Java files (more than 5000 lines of code), while there was no problem with smaller files (within 1000 or 2000 lines of code).

I made other optimizations, but this one was the most relevant, because it drastically reduced the amount of CPU used.

Try out this,

My installation is at D:\xampp\htdocs\advanced

\Yii::$app->basePath will give like D:\xampp\htdocs\advanced\backend.

\Yii::$app->request->BaseUrl will give like localhost\advanced\backend\web\

You may store the image using \Yii::$app->basePath and show it using \Yii::$app->request->BaseUrl

As you can read before, the ?v=1 ensures that your browser gets the version 1 of the file. When you have a new version, you just have to append a different version number and the browser will forget about the old version and loads the new one.

There is a gulp plugin which takes care of version your files during the build phase, so you don't have to do it manually. It's handy and you can easily integrate it in you build process. Here's the link: gulp-annotate

base64.h

#include <string>

std::string base64_encode(unsigned char const* , unsigned int len);
std::string base64_decode(std::string const& s);

Usage

const std::string s = "test";
std::string encoded = base64_encode(reinterpret_cast<const unsigned char*>(s.c_str()), s.length());
  std::string decoded = base64_decode(encoded);

The easiest way is probably to create an std::bitset representing the value, then stream that to cout.

#include <bitset>
...

char a = -58;
std::bitset<8> x(a);
std::cout << x << '\n';

short c = -315;
std::bitset<16> y(c);
std::cout << y << '\n';

JSON itself has no date format, it does not care how anyone stores dates. However, since this question is tagged with javascript, I assume you want to know how to store javascript dates in JSON. You can just pass in a date to the JSON.stringify method, and it will use Date.prototype.toJSON by default, which in turns uses Date.prototype.toISOString (MDN on Date.toJSON):

const json = JSON.stringify(new Date());
const parsed = JSON.parse(json); //2015-10-26T07:46:36.611Z
const date = new Date(parsed); // Back to date object

I also found it useful to use the reviver parameter of JSON.parse (MDN on JSON.parse) to automatically convert ISO strings back to javascript dates whenever I read JSON strings.

const isoDatePattern = new RegExp(/\d{4}-[01]\d-[0-3]\dT[0-2]\d:[0-5]\d:[0-5]\d\.\d+([+-][0-2]\d:[0-5]\d|Z)/);

const obj = {
 a: 'foo',
 b: new Date(1500000000000) // Fri Jul 14 2017, etc...
}
const json = JSON.stringify(obj);

// Convert back, use reviver function:
const parsed = JSON.parse(json, (key, value) => {
    if (typeof value === 'string' &&  value.match(isoDatePattern)){
        return new Date(value); // isostring, so cast to js date
    }
    return value; // leave any other value as-is
});
console.log(parsed.b); // // Fri Jul 14 2017, etc...

Restart Service with docker-compose file

docker-compose -f [COMPOSE_FILE_NAME].yml restart [SERVICE_NAME]

Use Case #1: If the COMPOSE_FILE_NAME is docker-compose.yml and service is worker

docker-compose restart worker

Use Case #2: If the file name is sample.yml and service is worker

docker-compose -f sample.yml restart worker

By default docker-compose looks for the docker-compose.yml if we run the docker-compose command, else we have flag to give specific file name with -f [FILE_NAME].yml

There once existed a plugin called JSEclipse that Adobe has subsequently sucked up and killed by making it available only by purchasing and installing FlexBuilder 3 (please someone prove me wrong). I found it to worked excellent but have since lost it since "upgrading" from Eclipse 3.4 to 3.4.1.

The feature I liked most was Content Outline.

In the Outline window of your Eclipse Screen, JSEclipse lists all classes in the currently opened file. It provides an overview of the class hierarchy and also method and property names. The outline makes heavy use of the code completion engine to find out more about how the code is structured. By clicking on the function entry in the list the cursor will be taken to the function declaration helping you navigate faster in long files with lots of class and method definitions

Use arrows or hjkl to get to one of the bracketing expressions, then v to select visual (i.e. selecting) mode, then % to jump to the other bracket.

For just reading the last element of a slice:

sl[len(sl)-1]

For removing it:

sl = sl[:len(sl)-1]

See this page about slice tricks

Use the DateTime.ToUniversalTime method.

Here's a cool ASP.NET Web control called Multi-Select List Field at http://www.xnodesystems.com/. It's capable of:

(1) Multi-select; (2) Auto-complete; (3) Validation.

In order to unit test code that relies on your database you need to setup a database or mock for each and every test.

1. Having a database (real or mocked) with a single state for all your tests will bite you quickly; you cannot test all records are valid and some aren't from the same data.
2. Setting up an in-memory database in a OneTimeSetup will have issues where the old database is not cleared down before the next test starts up. This will show as tests working when you run them individually, but failing when you run them all.
3. A Unit test should ideally only set what affects the test

I am working in an application that has a lot of tables with a lot of connections and some massive Linq blocks. These need testing. A simple grouping missed, or a join that results in more than 1 row will affect results.

To deal with this I have setup a heavy Unit Test Helper that is a lot of work to setup, but enables us to reliably mock the database in any state, and running 48 tests against 55 interconnected tables, with the entire database setup 48 times takes 4.7 seconds.

Here's how:

1. In the Db context class ensure each table class is set to virtual

   public virtual DbSet<Branch> Branches { get; set; }
   public virtual DbSet<Warehouse> Warehouses { get; set; }
   

2. In a UnitTestHelper class create a method to setup your database. Each table class is an optional parameter. If not supplied, it will be created through a Make method

   internal static Db Bootstrap(bool onlyMockPassedTables = false, List<Branch> branches = null, List<Products> products = null, List<Warehouses> warehouses = null)
   {
       if (onlyMockPassedTables == false) {
           branches ??= new List<Branch> { MakeBranch() };
           warehouses ??= new List<Warehouse>{ MakeWarehouse() };
       }
   

3. For each table class, each object in it is mapped to the other lists

       branches?.ForEach(b => {
           b.Warehouse = warehouses.FirstOrDefault(w => w.ID == b.WarehouseID);
       });
   
       warehouses?.ForEach(w => {
           w.Branches = branches.Where(b => b.WarehouseID == w.ID);
       });
   

4. And add it to the DbContext

        var context = new Db(new DbContextOptionsBuilder<Db>().UseInMemoryDatabase(Guid.NewGuid().ToString()).Options);
        context.Branches.AddRange(branches);
        context.Warehouses.AddRange(warehouses);
        context.SaveChanges();
        return context;
    }
   

5. Define a list of IDs to make is easier to reuse them and make sure joins are valid

    internal const int BranchID = 1;
    internal const int WarehouseID = 2;
   

6. Create a Make for each table to setup the most basic, but connected version it can be

    internal static Branch MakeBranch(int id = BranchID, string code = "The branch", int warehouseId = WarehouseID) => new Branch { ID = id, Code = code, WarehouseID = warehouseId };
    internal static Warehouse MakeWarehouse(int id = WarehouseID, string code = "B", string name = "My Big Warehouse") => new Warehouse { ID = id, Code = code, Name = name };
   

It's a lot of work, but it only needs doing once, and then your tests can be very focused because the rest of the database will be setup for it.

[Test]
[TestCase(new string [] {"ABC", "DEF"}, "ABC", ExpectedResult = 1)]
[TestCase(new string [] {"ABC", "BCD"}, "BC", ExpectedResult = 2)]
[TestCase(new string [] {"ABC"}, "EF", ExpectedResult = 0)]
[TestCase(new string[] { "ABC", "DEF" }, "abc", ExpectedResult = 1)]
public int Given_SearchingForBranchByName_Then_ReturnCount(string[] codesInDatabase, string searchString)
{
    // Arrange
    var branches = codesInDatabase.Select(x => UnitTestHelpers.MakeBranch(code: $"qqqq{x}qqq")).ToList();
    var db = UnitTestHelpers.Bootstrap(branches: branches);
    var service = new BranchService(db);

    // Act
    var result = service.SearchByName(searchString);

    // Assert
    return result.Count();
}

Same principle as the solutions above. But I had issues with Firefox 52.0 (32 bit) where large files (>40 MBytes) are truncated at random positions. Re-scheduling the call of revokeObjectUrl() fixes this issue.

function saveFile(blob, filename) {
  if (window.navigator.msSaveOrOpenBlob) {
    window.navigator.msSaveOrOpenBlob(blob, filename);
  } else {
    const a = document.createElement('a');
    document.body.appendChild(a);
    const url = window.URL.createObjectURL(blob);
    a.href = url;
    a.download = filename;
    a.click();
    setTimeout(() => {
      window.URL.revokeObjectURL(url);
      document.body.removeChild(a);
    }, 0)
  }
}

jsfiddle example

Since you have not mentioned what needs to be copied, I have left that section empty in the code below.

Also you don't need to move the email to the folder first and then run the macro in that folder. You can run the macro on the incoming mail and then move it to the folder at the same time.

This will get you started. I have commented the code so that you will not face any problem understanding it.

First paste the below mentioned code in the outlook module.

Then

1. Click on Tools~~>Rules and Alerts
2. Click on "New Rule"
3. Click on "start from a blank rule"
4. Select "Check messages When they arrive"
5. Under conditions, click on "with specific words in the subject"
6. Click on "specific words" under rules description.
7. Type the word that you want to check in the dialog box that pops up and click on "add".
8. Click "Ok" and click next
9. Select "move it to specified folder" and also select "run a script" in the same box
10. In the box below, specify the specific folder and also the script (the macro that you have in module) to run.
11. Click on finish and you are done.

When the new email arrives not only will the email move to the folder that you specify but data from it will be exported to Excel as well.

FOLLOWUP

To extract the contents from your email body, you can split it using SPLIT() and then parsing out the relevant information from it. See this example

Dim MyAr() As String

MyAr = Split(olMail.body, vbCrLf)

For i = LBound(MyAr) To UBound(MyAr)
    '~~> This will give you the contents of your email
    '~~> on separate lines
    Debug.Print MyAr(i)
Next i

Flat files do not allow providing meta information.

I would suggest writing out a HTML table containing the information you need, and let Excel read it instead. You can then use <b> tags to do what you ask for.

The following works for text entries both with and without spaces:

$("#mySelect1").find("option[text=" + text1 + "]").attr("selected", true);

I would prefer the C++ min/max functions, if you are using C++, because they are type-specific. fmin/fmax will force everything to be converted to/from floating point.

Also, the C++ min/max functions will work with user-defined types as long as you have defined operator< for those types.

HTH

void operator could be used here.
Instead of:

React.useEffect(() => {
    async function fetchData() {
    }
    fetchData();
}, []);

or

React.useEffect(() => {
    (async function fetchData() {
    })()
}, []);

you could write:

React.useEffect(() => {
    void async function fetchData() {
    }();
}, []);

It is a little bit cleaner and prettier.

Async effects could cause memory leaks so it is important to perform cleanup on component unmount. In case of fetch this could look like this:

function App() {
    const [ data, setData ] = React.useState([]);

    React.useEffect(() => {
        const abortController = new AbortController();
        void async function fetchData() {
            try {
                const url = 'https://jsonplaceholder.typicode.com/todos/1';
                const response = await fetch(url, { signal: abortController.signal });
                setData(await response.json());
            } catch (error) {
                console.log('error', error);
            }
        }();
        return () => {
            abortController.abort(); // cancel pending fetch request on component unmount
        };
    }, []);

    return <pre>{JSON.stringify(data, null, 2)}</pre>;
}

As @KaptajnKold had answered

var x = [ 'p0', 'p1', 'p2' ];
call_me.apply(this, x);

And you don't need to define every parameters for call_me function either. You can just use arguments

function call_me () {
    // arguments is a array consisting of params.
    // arguments[0] == 'p0',
    // arguments[1] == 'p1',
    // arguments[2] == 'p2'
}

Maybe this is what you are looking for. To check if a file exist and is not a link.

Try this command:

file="/usr/mda" 
[ -f $file ] && [ ! -L $file ] && echo "$file exists and is not a symlink"

This worked for me Visual C++ Redistributable Packages

The thing of it is there are 2 main protocol versions of WebSockets in use today. The old version which uses the [0x00][message][0xFF] protocol, and then there's the new version using Hybi formatted packets.

The old protocol version is used by Opera and iPod/iPad/iPhones so it's actually important that backward compatibility is implemented in WebSockets servers. With these browsers using the old protocol, I discovered that refreshing the page, or navigating away from the page, or closing the browser, all result in the browser automatically closing the connection. Great!!

However with browsers using the new protocol version (eg. Firefox, Chrome and eventually IE10), only closing the browser will result in the browser automatically closing the connection. That is to say, if you refresh the page, or navigate away from the page, the browser does NOT automatically close the connection. However, what the browser does do, is send a hybi packet to the server with the first byte (the proto ident) being 0x88 (better known as the close data frame). Once the server receives this packet it can forcefully close the connection itself, if you so choose.

One solution would be to auto-fill the inputs with whitespace characters, and have them clear on focus.

Example: http://nfdb.net/autofill.php

<!doctype html>
<html>
    <head>
        <title>Autofill Test</title>
        <script>
            var userfield;

            // After the document has loaded, manipulate DOM elements.
            window.addEventListener('load', function() {

                // Get the username field element.
                userfield = document.getElementById('user');

                // Listen to the 'focus' event on the input element.
                userfield.addEventListener('focus', function() {

                    // Checks if the value is the EM space character,
                    // and removes it when the input is recieves focus.
                    if (this.value == '\u2003') this.value = ''

                }, false);

                // Listen to the 'blur' event on the input element.
                // Triggered when the user focuses on another element or window.
                userfield.addEventListener('blur', function() {

                    // Checks if the value is empty (the user hasn't typed)
                    // and inserts the EM space character if necessary.
                    if (this.value == '') this.value = '\u2003';

                }, false);
            }, false);
        </script>
    </head>
    <body>
        <form method="GET" action="">
            <input id="user" name="username" type="text" value="&#8195;"/><br/>
            <input name="password" type="password" value=""/><br/>
            <input type="submit" value="Login">
        </form>
    </body>
</html>

This should stop the browser from auto-filling the fields, but still allow them to auto-complete.

Here's another example that clears the form inputs after the page loads. The advantage of this method is that the inputs never have any whitespace characters in them, the disadvantage is that there's a small possibility that the auto-filled values may be visible for a few milliseconds.

http://nfdb.net/autofill2.php

<!doctype html>
<html>
    <head>
        <title>Autofill Test</title>
        <script>
            var userfield, passfield;

            // Wait for the document to load, then call the clear function.
            window.addEventListener('load', function() {

                // Get the fields we want to clear.
                userfield = document.getElementById('user');
                passfield = document.getElementById('pass');

                // Clear the fields.
                userfield.value = '';
                passfield.value = '';

                // Clear the fields again after a very short period of time, in case the auto-complete is delayed.
                setTimeout(function() { userfield.value = ''; passfield.value = ''; }, 50);
                setTimeout(function() { userfield.value = ''; passfield.value = ''; }, 100);

            }, false);
        </script>
    </head>
    <body>
        <div>This form has autofill disabled:</div>
        <form name="login" method="GET" action="./autofill2.php">

            <input id="pass" name="password" type="password" value=""/><br/>
            <input type="submit" value="Login">

        <div>This form is untouched:</div>

if you wish to hide URL from the user, Show an AlertDialog as below.

myWebView.setWebChromeClient(new WebChromeClient() {

            @Override
            public boolean onJsAlert(WebView view, String url, String message, JsResult result) {
                Log.d(TAG, "onJsAlert url: " + url + "; message: " + message);
                AlertDialog.Builder builder = new AlertDialog.Builder(
                        mContext);
                builder.setMessage(message)
                        .setNeutralButton("OK", new OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialog, int arg1) {
                                dialog.dismiss();
                            }
                        }).show();
                result.cancel();
                return true;
            }
    }

Try this... it will work ....

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    self.title = ""
}

The above code will hide the text and show only the back arrow on navigation bar.

You can use random.uniform

import random
random.uniform(0, 1)

I'm using Ookii dialogs for a while and it work nice for WPF.

Here's the direct page:

https://github.com/augustoproiete/ookii-dialogs-wpf

Create a default struct as the other answers have mentioned:

struct MyStruct
{
    int flag;
}

MyStruct_default = {3};

However, the above code will not work in a header file - you will get error: multiple definition of 'MyStruct_default'. To solve this problem, use extern instead in the header file:

struct MyStruct
{
    int flag;
};

extern const struct MyStruct MyStruct_default;

And in the c file:

const struct MyStruct MyStruct_default = {3};

Hope this helps anyone having trouble with the header file.

One more thing to try!

When I copied all of my files, opened the project, and renamed it, everything changed to my new project name except for the test target! I got a linker error that said I was missing a file called "myOldProjectname.app". Here's what fixed it:

1. Click on your project settings and select your test target

2. Click on build settings and search for "test host"

3. Check those 2 file paths. Chances are that those 2 paths are still pointing at your old project name.

Hope that helps!

From S. Prakash, found at the MySQL forum:

SELECT table_schema "database name",
    sum( data_length + index_length ) / 1024 / 1024 "database size in MB",
    sum( data_free )/ 1024 / 1024 "free space in MB"
FROM information_schema.TABLES
GROUP BY table_schema; 

Or in a single line for easier copy-pasting:

SELECT table_schema "database name", sum( data_length + index_length ) / 1024 / 1024 "database size in MB", sum( data_free )/ 1024 / 1024 "free space in MB" FROM information_schema.TABLES GROUP BY table_schema; 

I think what you're looking for is not hashing but encryption. With hashing, you will not be able to retrieve the original filename from the "hash" variable. With encryption you can, and it is secure.

See AES in ASP.NET with VB.NET for more information about encryption in .NET.

This is quite a misleading status. It should be called "reading and filtering data".

This means that MySQL has some data stored on the disk (or in memory) which is yet to be read and sent over. It may be the table itself, an index, a temporary table, a sorted output etc.

If you have a 1M records table (without an index) of which you need only one record, MySQL will still output the status as "sending data" while scanning the table, despite the fact it has not sent anything yet.

this did it for me. you can vary the options for the output format to Base64.Default whatsoever.

// encode base64 from image
ByteArrayOutputStream baos = new ByteArrayOutputStream();
imageBitmap.compress(Bitmap.CompressFormat.PNG, 100, baos);
byte[] b = baos.toByteArray();
encodedString = Base64.encodeToString(b, Base64.URL_SAFE | Base64.NO_WRAP);

@Sparr is right, but I guess you expected byte array like byte[] in C#. It's the same solution as Sparr did but instead of HEX you expected int presentation (range from 0 to 255) of each char. You can do as follows:

$byte_array = unpack('C*', 'The quick fox jumped over the lazy brown dog');
var_dump($byte_array);  // $byte_array should be int[] which can be converted
                        // to byte[] in C# since values are range of 0 - 255

By using var_dump you can see that elements are int (not string).

   array(44) {  [1]=>  int(84)  [2]=>  int(104) [3]=>  int(101) [4]=>  int(32)
[5]=> int(113)  [6]=>  int(117) [7]=>  int(105) [8]=>  int(99)  [9]=>  int(107)
[10]=> int(32)  [11]=> int(102) [12]=> int(111) [13]=> int(120) [14]=> int(32)
[15]=> int(106) [16]=> int(117) [17]=> int(109) [18]=> int(112) [19]=> int(101)
[20]=> int(100) [21]=> int(32)  [22]=> int(111) [23]=> int(118) [24]=> int(101)
[25]=> int(114) [26]=> int(32)  [27]=> int(116) [28]=> int(104) [29]=> int(101)
[30]=> int(32)  [31]=> int(108) [32]=> int(97)  [33]=> int(122) [34]=> int(121)
[35]=> int(32)  [36]=> int(98)  [37]=> int(114) [38]=> int(111) [39]=> int(119)
[40]=> int(110) [41]=> int(32)  [42]=> int(100) [43]=> int(111) [44]=> int(103) }

Be careful: the output array is of 1-based index (as it was pointed out in the comment)

This answer improves on @aioobe 's answer. Two bugs in that answer were fixed.
1. n=0 should return -1.
2. nth occurence returned -1, but it worked on n-1th occurences.

Try this !

    public int nthOccurrence(String str, char c, int n) {
    if(n <= 0){
        return -1;
    }
    int pos = str.indexOf(c, 0);
    while (n-- > 1 && pos != -1)
        pos = str.indexOf(c, pos+1);
    return pos;
}

If you dont want to use external libraries, you can use URL and URLConnection classes from standard Java API.

An example looks like this:

String urlString = "http://wherever.com/someAction?param1=value1&param2=value2....";
URL url = new URL(urlString);
URLConnection conn = url.openConnection();
InputStream is = conn.getInputStream();
// Do what you want with that stream

@ECHO OFF
ECHO Welcome to my calculator!
ECHO What is the number you want to insert to find the sum?
SET /P Num1=
ECHO What is the second number? 
SET /P Num2=
SET /A Ans=%Num1%+%Num2%
ECHO The sum is: %Ans%
PAUSE>NUL

Installing a Python package often only includes some pure Python files. If the package includes data, scripts and or executables, these are installed in different directories from the pure Python files.

Assuming your package has no data/scripts/executables, and that you want your Python files to go into /python/packages/package_name (and not some subdirectory a few levels below /python/packages as when using --prefix), you can use the one time command:

pip install --install-option="--install-purelib=/python/packages" package_name

If you want all (or most) of your packages to go there, you can edit your ~/.pip/pip.conf to include:

[install]
install-option=--install-purelib=/python/packages

That way you can't forget about having to specify it again and again.

Any excecutables/data/scripts included in the package will still go to their default places unless you specify addition install options (--prefix/--install-data/--install-scripts, etc., for details look at the custom installation options).

It's hard to tell what you're going for in that example. exports = is about exporting from external modules, but the code sample you linked is an internal module.

Rule of thumb: If you write module foo { ... }, you're writing an internal module; if you write export something something at top-level in a file, you're writing an external module. It's somewhat rare that you'd actually write export module foo at top-level (since then you'd be double-nesting the name), and it's even rarer that you'd write module foo in a file that had a top-level export (since foo would not be externally visible).

The following things make sense (each scenario delineated by a horizontal rule):

// An internal module named SayHi with an exported function 'foo'
module SayHi {
    export function foo() {
       console.log("Hi");
    }

    export class bar { }
}

// N.B. this line could be in another file that has a
// <reference> tag to the file that has 'module SayHi' in it
SayHi.foo();
var b = new SayHi.bar();

file1.ts

// This *file* is an external module because it has a top-level 'export'
export function foo() {
    console.log('hi');
}

export class bar { }

file2.ts

// This file is also an external module because it has an 'import' declaration
import f1 = module('file1');
f1.foo();
var b = new f1.bar();

file1.ts

// This will only work in 0.9.0+. This file is an external
// module because it has a top-level 'export'
function f() { }
function g() { }
export = { alpha: f, beta: g };

file2.ts

// This file is also an external module because it has an 'import' declaration
import f1 = require('file1');
f1.alpha(); // invokes f
f1.beta(); // invokes g

I had same issue with my WPF RSS reader, I originally went with Awesomium (I think version 1.6) Awesomium is great. You get a lot of control for caching (images and HTML content), JavaScript execution, intercepting downloads and so forth. It's also super fast. The process isolation means when browser crashes it does not crash the app.

But it's also heavy, even release build adds about 10-15mb (can't remember exact number) and hence a slight start-up penalty. I then realized, only problem I had with IE browser control was that it would throw the JavaScript errors every now and again. But that was fixed with the following snippet.

I hardly used my app on XP or Vista but on Win 7 and above it never crashed (at least not because I used IE browser control)

IOleServiceProvider sp = browser.Document as IOleServiceProvider;
if (sp != null)
{
    IID_IWebBrowserApp = new Guid("0002DF05-0000-0000-C000-000000000046");
    Guid IID_IWebBrowser2 = new Guid("D30C1661-CDAF-11d0-8A3E-00C04FC9E26E");

    webBrowser;
    sp.QueryService(ref IID_IWebBrowserApp, ref IID_IWebBrowser2, out webBrowser);
    if (webBrowser != null)
    {
        webBrowser.GetType().InvokeMember("Silent", 
                BindingFlags.Instance | BindingFlags.Public | BindingFlags.PutDispProperty, null, webBrowser, new object[] { silent });
    }
}

BlobBuilder is obsolete, use Blob constructor instead:

URL.createObjectURL(new Blob([/*whatever content*/] , {type:'text/plain'}));

This returns a blob URL which you can then use in an anchor's href. You can also modify an anchor's download attribute to manipulate the file name:

<a href="/*assign url here*/" id="link" download="whatever.txt">download me</a>

Fiddled. If I recall correctly, there are arbitrary restrictions on trusted non-user initiated downloads; thus we'll stick with a link clicking which is seen as sufficiently user-initiated :)

Update: it's actually pretty trivial to save current document's html! Whenever our interactive link is clicked, we'll update its href with a relevant blob. After executing the click-bound event, that's the download URL that will be navigated to!

$('#link').on('click', function(e){
  this.href = URL.createObjectURL(
    new Blob([document.documentElement.outerHTML] , {type:'text/html'})
  );
});

Fiddled again.

from command line

python -c help('modules')

can be used to view all modules, and for specific modules

python -c help('os')

For Linux below will work

python -c "help('os')"

You could possibly create a cookie if thats allowed in your requirment. If you choose to take the cookie route then the solution could be as follows. Also the benefit with cookie is after the user closes the Browser and Re-opens, if the cookie has not been deleted the value will be persisted.

Cookie *Create and Store a Cookie:*

function setCookie(c_name,value,exdays)
{
var exdate=new Date();
exdate.setDate(exdate.getDate() + exdays);
var c_value=escape(value) + ((exdays==null) ? "" : "; expires="+exdate.toUTCString());
document.cookie=c_name + "=" + c_value;
}

The function which will return the specified cookie:

function getCookie(c_name)
{
var i,x,y,ARRcookies=document.cookie.split(";");
for (i=0;i<ARRcookies.length;i++)
{
  x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("="));
  y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1);
  x=x.replace(/^\s+|\s+$/g,"");
  if (x==c_name)
    {
    return unescape(y);
    }
  }
}

Display a welcome message if the cookie is set

function checkCookie()
{
var username=getCookie("username");
  if (username!=null && username!="")
  {
  alert("Welcome again " + username);
  }
else 
  {
  username=prompt("Please enter your name:","");
  if (username!=null && username!="")
    {
    setCookie("username",username,365);
    }
  }
}

The above solution is saving the value through cookies. Its a pretty standard way without storing the value on the server side.

Jquery

Set a value to the session storage.

Javascript:

$.sessionStorage( 'foo', {data:'bar'} );

Retrieve the value:

$.sessionStorage( 'foo', {data:'bar'} );

$.sessionStorage( 'foo' );Results:
{data:'bar'}

Local Storage Now lets take a look at Local storage. Lets say for example you have an array of variables that you are wanting to persist. You could do as follows:

var names=[];
names[0]=prompt("New name?");
localStorage['names']=JSON.stringify(names);

//...
var storedNames=JSON.parse(localStorage['names']);

Server Side Example using ASP.NET

Adding to Sesion

Session["FirstName"] = FirstNameTextBox.Text;
Session["LastName"] = LastNameTextBox.Text;

// When retrieving an object from session state, cast it to // the appropriate type.

ArrayList stockPicks = (ArrayList)Session["StockPicks"];

// Write the modified stock picks list back to session state.
Session["StockPicks"] = stockPicks;

I hope that answered your question.

Yes, the Jackson manual parser design is quite different from other libraries. In particular, you will notice that JsonNode has most of the functions that you would typically associate with array nodes from other API's. As such, you do not need to cast to an ArrayNode to use. Here's an example:

JSON:

{
    "objects" : ["One", "Two", "Three"]
}

Code:

final String json = "{\"objects\" : [\"One\", \"Two\", \"Three\"]}";

final JsonNode arrNode = new ObjectMapper().readTree(json).get("objects");
if (arrNode.isArray()) {
    for (final JsonNode objNode : arrNode) {
        System.out.println(objNode);
    }
}

Output:

"One"
"Two"
"Three"

Note the use of isArray to verify that the node is actually an array before iterating. The check is not necessary if you are absolutely confident in your datas structure, but its available should you need it (and this is no different from most other JSON libraries).

I had to combine Maiasaura and Svun answers to get it to work: using setwd and escaping all the slashes and spaces.

setwd('C:\\Users\\firstname\ lastname\\Desktop\\folder1\\folder2\\folder3')
data = read.csv("file.csv")
data

This solved the issue for me.

$(".testClick").click(function () {
         var value = $(this).attr("href");
         alert(value );     
}); 

When you use $(".className") you are getting the set of all elements that have that class. Then when you call attr it simply returns the value of the first item in the collection.

I found that JToken.Parse incorrectly parses invalid JSON such as the following:

{
"Id" : , 
"Status" : 2
}

Paste the JSON string into http://jsonlint.com/ - it is invalid.

So I use:

public static bool IsValidJson(this string input)

• Review the default app manifest file, AndroidManifest.xml, located in <app dir>/android/app/src/main

• Edit the android:label to your desired display name

For C++, there are various type-safe enum techniques available, and some of those (such as the proposed-but-never-submitted Boost.Enum) include support for getting the size of a enum.

The simplest approach, which works in C as well as C++, is to adopt a convention of declaring a ...MAX value for each of your enum types:

enum Folders { FA, FB, FC, Folders_MAX = FC };
ContainerClass *m_containers[Folders_MAX + 1];
....
m_containers[FA] = ...; // etc.

Edit: Regarding { FA, FB, FC, Folders_MAX = FC} versus {FA, FB, FC, Folders_MAX]: I prefer setting the ...MAX value to the last legal value of the enum for a few reasons:

1. The constant's name is technically more accurate (since Folders_MAX gives the maximum possible enum value).
2. Personally, I feel like Folders_MAX = FC stands out from other entries out a bit more (making it a bit harder to accidentally add enum values without updating the max value, a problem Martin York referenced).
3. GCC includes helpful warnings like "enumeration value not included in switch" for code such as the following. Letting Folders_MAX == FC + 1 breaks those warnings, since you end up with a bunch of ...MAX enumeration values that should never be included in switch.

switch (folder) 
{
  case FA: ...;
  case FB: ...;
  // Oops, forgot FC!
}

You could use a radio button/checkbox and set it to hide the button in css and then give it a label with an image.

input[type="radio"] {display: none}
input[type="radio"] + label span {display: block}

Then on the page:

<input type="radio" name="emotion" id="mysubmitradio" />
        <label for="mysubmitradio"><img src="images/f.jpg" />
    <span>if you need it</span></label>

And then set it to submit using javascript:

document.forms["myform"].submit();

Did you try InputMethodManager.SHOW_IMPLICIT in first window.

and for hiding in second window use InputMethodManager.HIDE_IMPLICIT_ONLY

EDIT :

If its still not working then probably you are putting it at the wrong place. Override onFinishInflate() and show/hide there.

@override
public void onFinishInflate() {
     /* code to show keyboard on startup */
    InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.showSoftInput(mUserNameEdit, InputMethodManager.SHOW_IMPLICIT);
}

Just looking at the message it sounds like one or more of the components that you reference, or one or more of their dependencies is not registered properly.

If you know which component it is you can use regsvr32.exe to register it, just open a command prompt, go to the directory where the component is and type regsvr32 filename.dll (assuming it's a dll), if it works, try to run the code again otherwise come back here with the error.

If you don't know which component it is, try re-installing/repairing the GIS software (I assume you've installed some GIS software that includes the component you're trying to use).

IISReset restarts the entire webserver (including all associated sites). If you're just looking to reset a single ASP.NET website, you should just recycle that AppDomain.

The most common way to reset an ASP.NET website is to edit the web.config file, but you can also create an admin page with the following:

public partial class Recycle : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        HttpRuntime.UnloadAppDomain();
    }
}

Here's a blog post I wrote with more info: Avoid IISRESET in ASP.NET Applications

I have a simpler solution. In your destination page (irc_online.php) add an auto-refresh tag in the header.

This is a real universal code, you can create 3 different story board:

Set your project Universal mode, and set your main story iPhone with the iPhone5 storyboard and the ipad main with iPad target storyboard, now add new storyboard target for iphone and modify the resolution for iphone 4s or less now implement your AppDelegate.m

iPhone4/4s (is the same for 3/3Gs) one for iPhone5 and make the project universal, with a new Storyboard target for iPad, now in to AppDelegate.m under the didFinishLaunching add this code:

    if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone){
        UIStoryboard *storyBoard;

        CGSize result = [[UIScreen mainScreen] bounds].size;
        CGFloat scale = [UIScreen mainScreen].scale;
        result = CGSizeMake(result.width *scale, result.height *scale);

//----------------HERE WE SETUP FOR IPHONE4/4s/iPod----------------------

        if(result.height == 960){
            storyBoard = [UIStoryboard storyboardWithName:@"iPhone4_Storyboard" bundle:nil];
            UIViewController *initViewController = [storyBoard instantiateInitialViewController];
            [self.window setRootViewController:initViewController];
        }

//----------------HERE WE SETUP FOR IPHONE3/3s/iPod----------------------

        if(result.height == 480){
            storyBoard = [UIStoryboard storyboardWithName:@"iPhone4_Storyboard" bundle:nil];
            UIViewController *initViewController = [storyBoard instantiateInitialViewController];
            [self.window setRootViewController:initViewController];
        }
    }

        return YES;
 }

So you have created a Universal app for iPhone 3/3Gs/4/4s/5 All gen of iPod, and All type of iPad

Remember to integrate all IMG with myImage.png and [email protected]

use

I had a similar problem, I solved it by explicitly adding the file's directory to the path list:

import os
import sys

file_dir = os.path.dirname(__file__)
sys.path.append(file_dir)

After that, I had no problem importing from the same directory.

Well, even the SELECT COUNT(*) FROM Table will be fairly inefficient, especially on large tables, since SQL Server really can't do anything but do a full table scan (clustered index scan).

Sometimes, it's good enough to know an approximate number of rows from the database, and in such a case, a statement like this might suffice:

SELECT 
    SUM(used_page_count) * 8 AS SizeKB,
    SUM(row_count) AS [RowCount], 
    OBJECT_NAME(OBJECT_ID) AS TableName
FROM 
    sys.dm_db_partition_stats
WHERE 
    OBJECT_ID = OBJECT_ID('YourTableNameHere')
    AND (index_id = 0 OR index_id = 1)
GROUP BY 
    OBJECT_ID

This will inspect the dynamic management view and extract the number of rows and the table size from it, given a specific table. It does so by summing up the entries for the heap (index_id = 0) or the clustered index (index_id = 1).

It's quick, it's easy to use, but it's not guaranteed to be 100% accurate or up to date. But in many cases, this is "good enough" (and put much less burden on the server).

Maybe that would work for you, too? Of course, to use it in EF, you'd have to wrap this up in a stored proc or use a straight "Execute SQL query" call.

Ah-ha! The Lodash Changelog says it all...

"Removed _.pluck in favor of _.map with iteratee shorthand"

var objects = [{ 'a': 1 }, { 'a': 2 }];

// in 3.10.1
_.pluck(objects, 'a'); // ? [1, 2]
_.map(objects, 'a'); // ? [1, 2]

// in 4.0.0
_.map(objects, 'a'); // ? [1, 2]

As of Python3 you no longer need to open devnull and can call subprocess.DEVNULL.

Your code would be updated as such:

import subprocess
text = 'Hello World.'
print(text)
subprocess.call(['espeak', text], stderr=subprocess.DEVNULL)

Nothing above made it work for me. The thing for me is that I was testing a subscription and i forgot SkuType.SUBS, changing it to INAPP for the reserved google test product fixed it.

Easy Java 9 solution with try with resources block

public static void copyInputStreamToFile(InputStream input, File file) {  

    try (OutputStream output = new FileOutputStream(file)) {
        input.transferTo(output);
    } catch (IOException ioException) {
        ioException.printStackTrace();
    }

}

java.io.InputStream#transferTo is available since Java 9.

Another alternative to get the first character after deleting it:

// Example string
let string = 'Example';

// Getting the first character and updtated string
[character, string] = [string[0], string.substr(1)];

console.log(character);
// 'E'

console.log(string);
// 'xample'

This part of the official documentation says clearly that it’s 255 Unicode characters for NTFS, exFAT and FAT32, and 127 Unicode or 254 ASCII characters for UDF.

Apart from that, the maximum path name length is always 32,760 Unicode characters, with each path component no more than 255 characters.

I find this approach a bit more flexible, here you just providing generator function that emits key, value pairs and can be easily extended to also iterate over lists.

def traverse(value, key=None):
    if isinstance(value, dict):
        for k, v in value.items():
            yield from traverse(v, k)
    else:
        yield key, value

Then you can write your own myprint function, then would print those key value pairs.

def myprint(d):
    for k, v in traverse(d):
        print(f"{k} : {v}")

A test:

myprint({
    'xml': {
        'config': {
            'portstatus': {
                'status': 'good',
            },
            'target': '1',
        },
        'port': '11',
    },
})

Output:

status : good
target : 1
port : 11

I tested this on Python 3.6.

I tried all the above and found this secret sauce

1. make sure pom.xml specifies your desired jdk.
2. make sure maven specifies your desired jdk.
3. make sure Projects specifies your desired jdk.
4. make sure Modules specifies your integer jdk AND Dependencies specifies your jdk. hth.

Taking Vaclav's answer and making it more Angular-like:

angular.module('myApp').filter('total', ['$parse', function ($parse) {
    return function (input, property) {
        var i = input instanceof Array ? input.length : 0,
            p = $parse(property);

        if (typeof property === 'undefined' || i === 0) {
            return i;
        } else if (isNaN(p(input[0]))) {
            throw 'filter total can count only numeric values';
        } else {
            var total = 0;
            while (i--)
                total += p(input[i]);
            return total;
        }
    };
}]);

This gives you the benefit of even accessing nested and array data:

{{data | total:'values[0].value'}}

An Ajax alternative is to set an invisible <iframe> as your form's target and read the contents of that <iframe> in its onload handler. But why bother when there's Ajax?

Note: I just wanted to mention this alternative since some of the answers claim that it's impossible to achieve this without Ajax.

You can concat the data in this way:

InfoDF = pd.DataFrame()
tempDF = pd.DataFrame(rows,columns=['id','min_date'])

InfoDF = pd.concat([InfoDF,tempDF])

Another way is to use purrr package

# example data like what is said above

@A Handcart And Mohair

set.seed(1)
m <- data.frame(matrix(sample(100, 20, replace = TRUE), ncol = 4))


library(purrr)
means <- map_dbl(m, mean)

> means
#  X1   X2   X3   X4 
#47.0 64.4 44.8 67.8 

pd.wide_to_long

You can add a prefix to your year columns and then feed directly to pd.wide_to_long. I won't pretend this is efficient, but it may in certain situations be more convenient than pd.melt, e.g. when your columns already have an appropriate prefix.

df.columns = np.hstack((df.columns[:2], df.columns[2:].map(lambda x: f'Value{x}')))

res = pd.wide_to_long(df, stubnames=['Value'], i='name', j='Date').reset_index()\
        .sort_values(['location', 'name'])

print(res)

   name        Date location  Value
0  test    Jan-2010        A     12
2  test    Feb-2010        A     20
4  test  March-2010        A     30
1   foo    Jan-2010        B     18
3   foo    Feb-2010        B     20
5   foo  March-2010        B     25

If you use Python3x then string is not the same type as for Python 2.x, you must cast it to bytes (encode it).

plaintext = input("Please enter the text you want to compress")
filename = input("Please enter the desired filename")
with gzip.open(filename + ".gz", "wb") as outfile:
    outfile.write(bytes(plaintext, 'UTF-8'))

Also do not use variable names like string or file while those are names of module or function.

EDIT @Tom

Yes, non-ASCII text is also compressed/decompressed. I use Polish letters with UTF-8 encoding:

plaintext = 'Polish text: acelnószzACELNÓSZZ'
filename = 'foo.gz'
with gzip.open(filename, 'wb') as outfile:
    outfile.write(bytes(plaintext, 'UTF-8'))
with gzip.open(filename, 'r') as infile:
    outfile_content = infile.read().decode('UTF-8')
print(outfile_content)

You can run javascript code at any time. AFAIK it is executed at the moment the browser reaches the <script> tag where it is in. But you cannot access elements that are not loaded yet.

So if you need access to elements, you should wait until the DOM is loaded (this does not mean the whole page is loaded, including images and stuff. It's only the structure of the document, which is loaded much earlier, so you usually won't notice a delay), using the DOMContentLoaded event or functions like $.ready in jQuery.

The struct module mimics C structures. It takes more CPU cycles for a processor to read a 16-bit word on an odd address or a 32-bit dword on an address not divisible by 4, so structures add "pad bytes" to make structure members fall on natural boundaries. Consider:

struct {                   11
    char a;      012345678901
    short b;     ------------
    char c;      axbbcxxxdddd
    int d;
};

This structure will occupy 12 bytes of memory (x being pad bytes).

Python works similarly (see the struct documentation):

>>> import struct
>>> struct.pack('BHBL',1,2,3,4)
'\x01\x00\x02\x00\x03\x00\x00\x00\x04\x00\x00\x00'
>>> struct.calcsize('BHBL')
12

Compilers usually have a way of eliminating padding. In Python, any of =<>! will eliminate padding:

>>> struct.calcsize('=BHBL')
8
>>> struct.pack('=BHBL',1,2,3,4)
'\x01\x02\x00\x03\x04\x00\x00\x00'

Beware of letting struct handle padding. In C, these structures:

struct A {       struct B {
    short a;         int a;
    char b;          char b;
};               };

are typically 4 and 8 bytes, respectively. The padding occurs at the end of the structure in case the structures are used in an array. This keeps the 'a' members aligned on correct boundaries for structures later in the array. Python's struct module does not pad at the end:

>>> struct.pack('LB',1,2)
'\x01\x00\x00\x00\x02'
>>> struct.pack('LBLB',1,2,3,4)
'\x01\x00\x00\x00\x02\x00\x00\x00\x03\x00\x00\x00\x04'

If you do mind extra spaces and newlines, you can use

conn.exec %w{select attr1, attr2, attr3, attr4, attr5, attr6, attr7
  from table1, table2, table3, etc, etc, etc, etc, etc,
  where etc etc etc etc etc etc etc etc etc etc etc etc etc} * ' '

(use %W for interpolated strings)

Use subDays() method:

$users = Users::where('status_id', 'active')
           ->where( 'created_at', '>', Carbon::now()->subDays(30))
           ->get();

Use mvn -X or mvn --debug to find out from which different locations Maven reads settings.xml. This switch activates debug logging. Just check the first lines of mvn --debug | findstr /i /c:using /c:reading.

Right, Maven uses the Java system property user.home as location for the .m2 folder.

But user.home does not always resolve to %USERPROFILE%\.m2. If you have moved the location of your Desktop folder to another place, user.home might resolve to the parent directory of this new Desktop folder. This happens when using Windows Vista or a more recent Windows together with Java 7 or any older Java version.

The blog post Java’s “user.home” is Wrong on Windows describes it very well and gives links to the official bug reports. The bug is marked as resolved in Java 8. The comment of the blog's visitor Lars proposes a nice workaround.

If the results table of your stored proc is too complicated to type out the "create table" statement by hand, and you can't use OPENQUERY OR OPENROWSET, you can use sp_help to generate the list of columns and data types for you. Once you have the list of columns, it's just a matter of formatting it to suit your needs.

Step 1: Add "into #temp" to the output query (e.g. "select [...] into #temp from [...]").

The easiest way is to edit the output query in the proc directly. if you can't change the stored proc, you can copy the contents into a new query window and modify the query there.

Step 2: Run sp_help on the temp table. (e.g. "exec tempdb..sp_help #temp")

After creating the temp table, run sp_help on the temp table to get a list of the columns and data types including the size of varchar fields.

Step 3: Copy the data columns & types into a create table statement

I have an Excel sheet that I use to format the output of sp_help into a "create table" statement. You don't need anything that fancy, just copy and paste into your SQL editor. Use the column names, sizes, and types to construct a "Create table #x [...]" or "declare @x table [...]" statement which you can use to INSERT the results of the stored procedure.

Step 4: Insert into the newly created table

Now you'll have a query that's like the other solutions described in this thread.

DECLARE @t TABLE 
(
   --these columns were copied from sp_help
   COL1 INT,
   COL2 INT   
)

INSERT INTO @t 
Exec spMyProc 

This technique can also be used to convert a temp table (#temp) to a table variable (@temp). While this may be more steps than just writing the create table statement yourself, it prevents manual error such as typos and data type mismatches in large processes. Debugging a typo can take more time than writing the query in the first place.

The && function is not vectorized. You need the & function:

EUR <- PCs[which(PCs$V13 < 9 & PCs$V13 > 3), ]

If you want to redirect your webpage to another HTML FILE, just use as followed:

<meta http-equiv="refresh" content"2;otherpage.html">

2 being the seconds you want the client to wait before redirecting. Use "url=" only when it's an URL, to redirect to an HTML file just write the name after the ';'

You need to reference the cout's namespace std somehow. For instance, insert

using std::cout;
using std::endl;

on top of your function definition, or the file.

This may be a good explanation example

CREATE TABLE employees (
id INTEGER NOT NULL PRIMARY KEY,
managerId INTEGER REFERENCES employees(id), 
name VARCHAR(30) NOT NULL
);

INSERT INTO employees(id, managerId, name) VALUES(1, NULL, 'John');
INSERT INTO employees(id, managerId, name) VALUES(2, 1, 'Mike');

-- Explanation: -- In this example. -- John is Mike's manager. Mike does not manage anyone. -- Mike is the only employee who does not manage anyone.

_MSC_VER should be defined to a specific version number. You can either #ifdef on it, or you can use the actual define and do a runtime test. (If for some reason you wanted to run different code based on what compiler it was compiled with? Yeah, probably you were looking for the #ifdef. :))

You can find the Team ID via this link: https://developer.apple.com/membercenter/index.action#accountSummary

How about storing it in a variable?

#extraargs=-F
ls -l $extraargs -a /etc

Try:

#your_div_id {
  width: 855px;
  margin:0 auto;
  text-align: center;
}

You can use jquery-disablescroll to solve the problem:

• Disable scrolling: $window.disablescroll();
• Enable scrolling again: $window.disablescroll("undo");

Supports handleWheel, handleScrollbar, handleKeys and scrollEventKeys.

This error happens when you have a ViewBag Non-Existent in your razor code calling a method.

Controller

public ActionResult Accept(int id)
{
    return View();
}

razor:

<div class="form-group">
      @Html.LabelFor(model => model.ToId, "To", htmlAttributes: new { @class = "control-label col-md-2" })
     <div class="col-md-10">
           @Html.Flag(Model.from)
     </div>
</div>
<div class="form-group">
     <div class="col-md-10">
          <input value="@ViewBag.MaximounAmount.ToString()" />@* HERE is the error *@ 
     </div>
</div>

For some reason, the .net aren't able to show the error in the correct line.

Normally this causes a lot of wasted time.

The best way is to use display:

inline-block; 

and

overflow: hidden;

You can use tr to convert from DOS to Unix; however, you can only do this safely if CR appears in your file only as the first byte of a CRLF byte pair. This is usually the case. You then use:

tr -d '\015' <DOS-file >UNIX-file

Note that the name DOS-file is different from the name UNIX-file; if you try to use the same name twice, you will end up with no data in the file.

You can't do it the other way round (with standard 'tr').

If you know how to enter carriage return into a script (control-V, control-M to enter control-M), then:

sed 's/^M$//'     # DOS to Unix
sed 's/$/^M/'     # Unix to DOS

where the '^M' is the control-M character. You can also use the bash ANSI-C Quoting mechanism to specify the carriage return:

sed $'s/\r$//'     # DOS to Unix
sed $'s/$/\r/'     # Unix to DOS

However, if you're going to have to do this very often (more than once, roughly speaking), it is far more sensible to install the conversion programs (e.g. dos2unix and unix2dos, or perhaps dtou and utod) and use them.

If you need to process entire directories and subdirectories, you can use zip:

zip -r -ll zipfile.zip somedir/
unzip zipfile.zip

This will create a zip archive with line endings changed from CRLF to CR. unzip will then put the converted files back in place (and ask you file by file - you can answer: Yes-to-all). Credits to @vmsnomad for pointing this out.

Okay so ideal permissions look like this
For ssh directory (You can get this by typing ls -ld ~/.ssh/)
drwx------ 2 oroborus oroborus 4096 Nov 28 12:05 /home/oroborus/.ssh/

d means directory, rwx means the user oroborus has read write and execute permission. Here oroborus is my computer name, you can find yours by echoing $USER. The second oroborus is actually the group. You can read more about what does each field mean here. It is very important to learn this because if you are working on ubuntu/osx or any Linux distro chances are you will encounter it again.

Now to make your permission look like this, you need to type
sudo chmod 700 ~/.ssh

7 in binary is 111 which means read 1 write 1 and execute 1, you can decode 6 by similar logic means only read-write permissions

You have given your user read write and execute permissions. Make sure your file permissions look like this.

total 20
-rw------- 1 oroborus oroborus  418 Nov  8  2014 authorized_keys
-rw------- 1 oroborus oroborus   34 Oct 19 14:25 config
-rw------- 1 oroborus oroborus 1679 Nov 15  2015 id_rsa
-rw------- 1 oroborus oroborus  418 Nov 15  2015 id_rsa.pub
-rw-r--r-- 1 oroborus root      222 Nov 28 12:12 known_hosts

You have given here read-write permission to your user here for all files. You can see this by typing ls -l ~/.ssh/

This issue occurs because ssh is a program is trying to write to a file called known_hosts in its folder. While writing if it knows that it doesn't have sufficient permissions it will not write in that file and hence fail. This is my understanding of the issue, more knowledgeable people can throw more light in this. Hope it helps

This might me the most simple solution use like any

select *
from jobdetails
where job_no like any ('0711%', '0712%')

In Teradata this works fine.

When you want to copy a sheet named "mySheet" and use .Copy After:=, Excel first names the copied sheet exactly the same and simply adds ' (2)' so that its final name is "mySheet (2)".

Hidden or Not, doesn't matter. It rocks with 2 lines of code, adding the copied sheet at the end of the Workbook!!!

Example:

Sheets("mySheet").Copy After:=Sheets(ThisWorkbook.Sheets.count)
Sheets("mySheet (2)").name = "TheNameYouWant"

Simple no!

I found this worked best for me.

In AndroidManifest.xml <activity> element add android:windowSoftInputMode="stateHidden"

This always hides the keyboard when entering the activity.

Make sure you use the right doctype.

eg.

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">

or just

<!doctype html>

and also read and understand how compatibility modes and developer toolbar for IE work and set modes for IE:

EXPLAIN PLAN FOR

In SQL Developer, you don't have to use EXPLAIN PLAN FOR statement. Press F10 or click the Explain Plan icon.

It will be then displayed in the Explain Plan window.

If you are using SQL*Plus then use DBMS_XPLAN.

For example,

SQL> EXPLAIN PLAN FOR
  2  SELECT * FROM DUAL;

Explained.

SQL> SELECT * FROM TABLE(DBMS_XPLAN.DISPLAY);

I had the same problem, and even with the solutions provided here it did not work. The checkboxes would simply not change, their Value would remain null. It took me ages to realize my dumbness:

Turns out, I called the form1.PopulateDataGridView(my data) on the Form derived class Form1 before I called form1.Show(). When I changed up the order, that is to call Show() first, and then read the data and fill in the checkboxes, the value did not stay null.

cast (field1 as decimal(53,8)
) field 1

The default is: decimal(18,0)

All above not worked for me, but this was: Check that the name of Root element of class is exactly like the one from XML case sensitive.

You need to link with the math library:

gcc -o sphere sphere.c -lm

The error you are seeing: error: ld returned 1 exit status is from the linker ld (part of gcc that combines the object files) because it is unable to find where the function pow is defined.

Including math.h brings in the declaration of the various functions and not their definition. The def is present in the math library libm.a. You need to link your program with this library so that the calls to functions like pow() are resolved.

You can simply add the root directory path in the express app variable and get this path from the app. For this add app.set('rootDirectory', __dirname); in your index.js or app.js file. And use req.app.get('rootDirectory') for getting the root directory path in your code.

we can get the code below the video. In the share option, we will have an option embed. If we click on the embed we will get the code snippet for that video.

which will be similar to the below code

<iframe width="560" height="315" src="https://www.youtube.com/embed/GZh_Kj1rS74" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>

The above code will help you to get the full-screen option.

I see a few answers here, most of them complicated or with some cons (additional divs, text-align doesn't work because of display: inline-block). I think this is the simplest and problem-free solution:

HTML:

<table>
    <!-- Rows -->
    <tr>
        <td>E-MAIL</td>
        <td><input name="email" type="email" /></td>
    </tr>
    <tr>
        <td></td>
        <td><input type="submit" value="Register!" /></td>
    </tr>
</table>

CSS:

table input[type="submit"] {
    display: block;
    margin: 0 auto;
}

One more solution

<a href="javascript:history.go(0)">Reload</a>

Pretty late response but you can do the following in Kotlin:

activity?.applicationContext?.let { SymptomsAdapters(it, param2, param3, ...) }

(?.) is for safe null operation to prevent from the null pointer exception.

You do not want to create a new context as that can lead to memory leaks when interchanging between fragments or when the device changes rotation.

And as someone mentioned above, in Java you can obtain context in a fragment by doing the following:

getActivity().getApplicationContext()

Hi~I found a solution which is much better,from: https://gist.github.com/ikew0ng/8297033

    /**
 * Remove all entries from the backStack of this fragmentManager.
 *
 * @param fragmentManager the fragmentManager to clear.
 */
private void clearBackStack(FragmentManager fragmentManager) {
    if (fragmentManager.getBackStackEntryCount() > 0) {
        FragmentManager.BackStackEntry entry = fragmentManager.getBackStackEntryAt(0);
        fragmentManager.popBackStack(entry.getId(), FragmentManager.POP_BACK_STACK_INCLUSIVE);
    }
}

import requests

print(response)

If this still isn't working try unchecking "Enable Protected Mode" in IE.
Add your site to Local Intranet in Tools -> Internet Option -> Security Tab Then uncheck "Enable Protected Mode" Restart IE

You have to reimplement it using <xsl:choose> tag:

       <xsl:choose>
         <xsl:when test="$CreatedDate > $IDAppendedDate">
           <h2> mooooooooooooo </h2>
         </xsl:when>
         <xsl:otherwise>
          <h2> dooooooooooooo </h2>
         </xsl:otherwise>
       </xsl:choose>

Good question.

True regular languages can not decide arbitrarily deeply nested well-formed parenthesis. If your alphabet contains '(' and ')' the goal is to decide if a string of these has well-formed matching parenthesis. Since this is a necessary requirement for regular expressions the answer is no.

However, if you loosen the requirement and add recursion you can probably do it. The reason is that the recursion can act as a stack letting you "count" the current nesting depth by pushing onto this stack.

Russ Cox wrote "Regular Expression Matching Can Be Simple And Fast" which is a wonderful treatise on regex engine implementation.

From my own experience with webwork, a middleware was stuff between users (the web browser) and the backend database. It was the software that took stuff that users put in (example: orders for iPads, did some magical business logic, i.e. check if there are enough iPads available to fill the order) and updated the backend database to reflect those changes.

Here's a more generic version of the solution above from @herbertD :

private void resizeView(View view, int newWidth, int newHeight) { 
    try { 
        Constructor<? extends LayoutParams> ctor = view.getLayoutParams().getClass().getDeclaredConstructor(int.class, int.class); 
        view.setLayoutParams(ctor.newInstance(newWidth, newHeight));   
    } catch (Exception e) { 
        e.printStackTrace(); 
    }
}

Try these:

1. Set the missing viewbox and fill in the height and width values of the set height and height attributes in the svg tag

2. Then scale the picture simply by setting the height and width to the desired percent values. Good luck.

3. Set a fixed aspect ratio with preserveAspectRatio="X200Y200 meet (e.g. 200px), but it's not necessary

e.g.

 <svg
   xmlns:dc="http://purl.org/dc/elements/1.1/"
   xmlns:cc="http://creativecommons.org/ns#"
   xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"

Perhaps the simplest solution uses one of my favorite little-known functions, strcspn():

buffer[strcspn(buffer, "\n")] = 0;

If you want it to also handle '\r' (say, if the stream is binary):

buffer[strcspn(buffer, "\r\n")] = 0; // works for LF, CR, CRLF, LFCR, ...

The function counts the number of characters until it hits a '\r' or a '\n' (in other words, it finds the first '\r' or '\n'). If it doesn't hit anything, it stops at the '\0' (returning the length of the string).

Note that this works fine even if there is no newline, because strcspn stops at a '\0'. In that case, the entire line is simply replacing '\0' with '\0'.

Simply Abstract Data Type is nothing but a set of operation and set of data is used for storing some other data efficiently in the machine. There is no need of any perticular type declaration. It just require a implementation of ADT.

All of the current answers on this thread must have been a bit dated. As of pandas version 0.24.0, the .to_flat_index() does what you need.

From panda's own documentation:

MultiIndex.to_flat_index()

Convert a MultiIndex to an Index of Tuples containing the level values.

A simple example from its documentation:

import pandas as pd
print(pd.__version__) # '0.23.4'
index = pd.MultiIndex.from_product(
        [['foo', 'bar'], ['baz', 'qux']],
        names=['a', 'b'])

print(index)
# MultiIndex(levels=[['bar', 'foo'], ['baz', 'qux']],
#           codes=[[1, 1, 0, 0], [0, 1, 0, 1]],
#           names=['a', 'b'])

Applying to_flat_index():

index.to_flat_index()
# Index([('foo', 'baz'), ('foo', 'qux'), ('bar', 'baz'), ('bar', 'qux')], dtype='object')

Using it to replace existing pandas column

An example of how you'd use it on dat, which is a DataFrame with a MultiIndex column:

dat = df.loc[:,['name','workshop_period','class_size']].groupby(['name','workshop_period']).describe()
print(dat.columns)
# MultiIndex(levels=[['class_size'], ['count', 'mean', 'std', 'min', '25%', '50%', '75%', 'max']],
#            codes=[[0, 0, 0, 0, 0, 0, 0, 0], [0, 1, 2, 3, 4, 5, 6, 7]])

dat.columns = dat.columns.to_flat_index()
print(dat.columns)
# Index([('class_size', 'count'),  ('class_size', 'mean'),
#     ('class_size', 'std'),   ('class_size', 'min'),
#     ('class_size', '25%'),   ('class_size', '50%'),
#     ('class_size', '75%'),   ('class_size', 'max')],
#  dtype='object')

You should declare the variable in a header file:

extern int x;

and then define it in one C file:

int x;

In C, the difference between a definition and a declaration is that the definition reserves space for the variable, whereas the declaration merely introduces the variable into the symbol table (and will cause the linker to go looking for it when it comes to link time).

Why are these new categories needed? Are the WG21 gods just trying to confuse us mere mortals?

I don't feel that the other answers (good though many of them are) really capture the answer to this particular question. Yes, these categories and such exist to allow move semantics, but the complexity exists for one reason. This is the one inviolate rule of moving stuff in C++11:

Thou shalt move only when it is unquestionably safe to do so.

That is why these categories exist: to be able to talk about values where it is safe to move from them, and to talk about values where it is not.

In the earliest version of r-value references, movement happened easily. Too easily. Easily enough that there was a lot of potential for implicitly moving things when the user didn't really mean to.

Here are the circumstances under which it is safe to move something:

1. When it's a temporary or subobject thereof. (prvalue)
2. When the user has explicitly said to move it.

If you do this:

SomeType &&Func() { ... }

SomeType &&val = Func();
SomeType otherVal{val};

What does this do? In older versions of the spec, before the 5 values came in, this would provoke a move. Of course it does. You passed an rvalue reference to the constructor, and thus it binds to the constructor that takes an rvalue reference. That's obvious.

There's just one problem with this; you didn't ask to move it. Oh, you might say that the && should have been a clue, but that doesn't change the fact that it broke the rule. val isn't a temporary because temporaries don't have names. You may have extended the lifetime of the temporary, but that means it isn't temporary; it's just like any other stack variable.

If it's not a temporary, and you didn't ask to move it, then moving is wrong.

The obvious solution is to make val an lvalue. This means that you can't move from it. OK, fine; it's named, so its an lvalue.

Once you do that, you can no longer say that SomeType&& means the same thing everwhere. You've now made a distinction between named rvalue references and unnamed rvalue references. Well, named rvalue references are lvalues; that was our solution above. So what do we call unnamed rvalue references (the return value from Func above)?

It's not an lvalue, because you can't move from an lvalue. And we need to be able to move by returning a &&; how else could you explicitly say to move something? That is what std::move returns, after all. It's not an rvalue (old-style), because it can be on the left side of an equation (things are actually a bit more complicated, see this question and the comments below). It is neither an lvalue nor an rvalue; it's a new kind of thing.

What we have is a value that you can treat as an lvalue, except that it is implicitly moveable from. We call it an xvalue.

Note that xvalues are what makes us gain the other two categories of values:

• A prvalue is really just the new name for the previous type of rvalue, i.e. they're the rvalues that aren't xvalues.

• Glvalues are the union of xvalues and lvalues in one group, because they do share a lot of properties in common.

So really, it all comes down to xvalues and the need to restrict movement to exactly and only certain places. Those places are defined by the rvalue category; prvalues are the implicit moves, and xvalues are the explicit moves (std::move returns an xvalue).

The attribute mentioned in the other answer is validation mechanism and not a representation of state. Please refer to the http://www.w3.org/TR/xmlschema-1/#xsi_nil

XML Schema: Structures introduces a mechanism for signaling that an element should be accepted as ·valid· when it has no content despite a content type which does not require or even necessarily allow empty content. An element may be ·valid· without content if it has the attribute xsi:nil with the value true. An element so labeled must be empty, but can carry attributes if permitted by the corresponding complex type.

To clarify this answer: Content

  <Book>
    <!--Invalid construct since the element attribute xsi:nil="true" signal that the element must be empty-->
    <BuildAttributes HardCover="true" Glued="true" xsi:nil="true">

Ruby have binary reading

data = IO.binread(path/filaname)

or if less than Ruby 1.9.2

data = IO.read(path/file)

If you want to use it in plain SQL, I would let the store procedure fill a table or temp table with the resulting rows (or go for @Tony Andrews approach).
If you want to use @Thilo's solution, you have to loop the cursor using PL/SQL. Here an example: (I used a procedure instead of a function, like @Thilo did)

create or replace procedure myprocedure(retval in out sys_refcursor) is
begin
  open retval for
    select TABLE_NAME from user_tables;
end myprocedure;

 declare 
   myrefcur sys_refcursor;
   tablename user_tables.TABLE_NAME%type;
 begin
   myprocedure(myrefcur);
   loop
     fetch myrefcur into tablename;
     exit when myrefcur%notfound;
     dbms_output.put_line(tablename);
   end loop;
   close myrefcur;
 end;

I'm using ui-bootstrap-tpls.js and what worked for me is that I searched in the whole project for fade and found 3 places where this was being set in the mentioned file.

I went through the find results and saw that 2 of the changes were being done on the modal and the other one was being set on the tool tip animation. Note the difference in below code

'uib-modal-animation-class': 'fade'
'tooltip-animation-class="fade"'

What I did to solve the issue was to add the show class for the uib-modal

'uib-modal-animation-class': 'fade show'

As indicated by @TerryA, many answers discuss how to find one index.

more_itertools is a third-party library with tools to locate multiple indices within an iterable.

Given

import more_itertools as mit


iterable = ["foo", "bar", "baz", "ham", "foo", "bar", "baz"]

Code

Find indices of multiple observations:

list(mit.locate(iterable, lambda x: x == "bar"))
# [1, 5]

Test multiple items:

list(mit.locate(iterable, lambda x: x in {"bar", "ham"}))
# [1, 3, 5]

See also more options with more_itertools.locate. Install via > pip install more_itertools.

I use the && expression which works perfectly for me.

For example,

<button ng-model="vm.slideOneValid" ng-disabled="!vm.slideOneValid" ng-click="vm.slideOneValid && vm.nextSlide()" class="btn btn-light-green btn-medium pull-right">Next</button>

If vm.slideOneValid is false, the second part of the expression is not fired. I know this is putting logic into the DOM, but it's a quick a dirty way to get ng-disabled and ng-click to place nice.

Just remember to add ng-model to the element to make ng-disabled work.

A pure bash solution:

shopt -s nullglob
dirs=( /path/to/directory/*/ )
echo "There are ${#dirs[@]} (non-hidden) directories"

If you also want to count the hidden directories:

shopt -s nullglob dotglob
dirs=( /path/to/directory/*/ )
echo "There are ${#dirs[@]} directories (including hidden ones)"

Note that this will also count links to directories. If you don't want that, it's a bit more difficult with this method.

Using find:

find /path/to/directory -type d \! -name . -prune -exec printf x \; | wc -c

The trick is to output an x to stdout each time a directory is found, and then use wc to count the number of characters. This will count the number of all directories (including hidden ones), excluding links.

The methods presented here are all safe wrt to funny characters that can appear in file names (spaces, newlines, glob characters, etc.).

Google now has a documentation page dedicated to Maps URLs:

https://developers.google.com/maps/documentation/urls/guide

An API key is not required.

Manipulating one of the examples, I came up with this URL scheme that fits your question:

https://www.google.com/maps/search/<search term>/@<coordinates>,<zoom level>z

A valid example of this would be:

https://www.google.com/maps/search/pizza/@41.089988,-81.542901,12z

This should show you all of the pizza places around Akron, Ohio.

This is only a warning: your code still works, but probably won't work in the future as the method is deprecated. See the relevant source of Chromium and corresponding patch.

This has already been recognised and fixed in jQuery 1.11 (see here and here).

I think you are not configured properly,

if you are using XAMPP then you can easily send mail from localhost.

for example you can configure C:\xampp\php\php.ini and c:\xampp\sendmail\sendmail.ini for gmail to send mail.

in C:\xampp\php\php.ini find extension=php_openssl.dll and remove the semicolon from the beginning of that line to make SSL working for gmail for localhost.

in php.ini file find [mail function] and change

SMTP=smtp.gmail.com
smtp_port=587
sendmail_from = [email protected]
sendmail_path = "C:\xampp\sendmail\sendmail.exe -t"

(use the above send mail path only and it will work)

Now Open C:\xampp\sendmail\sendmail.ini. Replace all the existing code in sendmail.ini with following code

[sendmail]

smtp_server=smtp.gmail.com
smtp_port=587
error_logfile=error.log
debug_logfile=debug.log
[email protected]
auth_password=my-gmail-password
[email protected]

Now you have done!! create php file with mail function and send mail from localhost.

Update

First, make sure you PHP installation has SSL support (look for an "openssl" section in the output from phpinfo()).

You can set the following settings in your PHP.ini:

ini_set("SMTP","ssl://smtp.gmail.com");
ini_set("smtp_port","465");
