Try the following code with an added request property:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;

public class SocketConnection
{
    public static String getURLSource(String url) throws IOException
    {
        URL urlObject = new URL(url);
        URLConnection urlConnection = urlObject.openConnection();
        urlConnection.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.95 Safari/537.11");

        return toString(urlConnection.getInputStream());
    }

    private static String toString(InputStream inputStream) throws IOException
    {
        try (BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8")))
        {
            String inputLine;
            StringBuilder stringBuilder = new StringBuilder();
            while ((inputLine = bufferedReader.readLine()) != null)
            {
                stringBuilder.append(inputLine);
            }

            return stringBuilder.toString();
        }
    }
}

Here is my ES3 commented solution (gory details after the code):

function object_equals( x, y ) {
  if ( x === y ) return true;
    // if both x and y are null or undefined and exactly the same

  if ( ! ( x instanceof Object ) || ! ( y instanceof Object ) ) return false;
    // if they are not strictly equal, they both need to be Objects

  if ( x.constructor !== y.constructor ) return false;
    // they must have the exact same prototype chain, the closest we can do is
    // test there constructor.

  for ( var p in x ) {
    if ( ! x.hasOwnProperty( p ) ) continue;
      // other properties were tested using x.constructor === y.constructor

    if ( ! y.hasOwnProperty( p ) ) return false;
      // allows to compare x[ p ] and y[ p ] when set to undefined

    if ( x[ p ] === y[ p ] ) continue;
      // if they have the same strict value or identity then they are equal

    if ( typeof( x[ p ] ) !== "object" ) return false;
      // Numbers, Strings, Functions, Booleans must be strictly equal

    if ( ! object_equals( x[ p ],  y[ p ] ) ) return false;
      // Objects and Arrays must be tested recursively
  }

  for ( p in y )
    if ( y.hasOwnProperty( p ) && ! x.hasOwnProperty( p ) )
      return false;
        // allows x[ p ] to be set to undefined

  return true;
}

In developing this solution, I took a particular look at corner cases, efficiency, yet trying to yield a simple solution that works, hopefully with some elegance. JavaScript allows both null and undefined properties and objects have prototypes chains that can lead to very different behaviors if not checked.

First I have chosen to not extend Object.prototype, mostly because null could not be one of the objects of the comparison and that I believe that null should be a valid object to compare with another. There are also other legitimate concerns noted by others regarding the extension of Object.prototype regarding possible side effects on other's code.

Special care must taken to deal the possibility that JavaScript allows object properties can be set to undefined, i.e. there exists properties which values are set to undefined. The above solution verifies that both objects have the same properties set to undefined to report equality. This can only be accomplished by checking the existence of properties using Object.hasOwnProperty( property_name ). Also note that JSON.stringify() removes properties that are set to undefined, and that therefore comparisons using this form will ignore properties set to the value undefined.

Functions should be considered equal only if they share the same reference, not just the same code, because this would not take into account these functions prototype. So comparing the code string does not work to guaranty that they have the same prototype object.

The two objects should have the same prototype chain, not just the same properties. This can only be tested cross-browser by comparing the constructor of both objects for strict equality. ECMAScript 5 would allow to test their actual prototype using Object.getPrototypeOf(). Some web browsers also offer a __proto__ property that does the same thing. A possible improvement of the above code would allow to use one of these methods whenever available.

The use of strict comparisons is paramount here because 2 should not be considered equal to "2.0000", nor false should be considered equal to null, undefined, or 0.

Efficiency considerations lead me to compare for equality of properties as soon as possible. Then, only if that failed, look for the typeof these properties. The speed boost could be significant on large objects with lots of scalar properties.

No more that two loops are required, the first to check properties from the left object, the second to check properties from the right and verify only existence (not value), to catch these properties which are defined with the undefined value.

Overall this code handles most corner cases in only 16 lines of code (without comments).

Update (8/13/2015). I have implemented a better version, as the function value_equals() that is faster, handles properly corner cases such as NaN and 0 different than -0, optionally enforcing objects' properties order and testing for cyclic references, backed by more than 100 automated tests as part of the Toubkal project test suite.

Inspired by Johann's table, I've decided to extend the table. I wanted to see which ASCII characters get encoded.

var ascii = " !\"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\\]^_`abcdefghijklmnopqrstuvwxyz{|}~";_x000D_
_x000D_
var encoded = [];_x000D_
_x000D_
ascii.split("").forEach(function (char) {_x000D_
    var obj = { char };_x000D_
    if (char != encodeURI(char))_x000D_
        obj.encodeURI = encodeURI(char);_x000D_
    if (char != encodeURIComponent(char))_x000D_
        obj.encodeURIComponent = encodeURIComponent(char);_x000D_
    if (obj.encodeURI || obj.encodeURIComponent)_x000D_
        encoded.push(obj);_x000D_
});_x000D_
_x000D_
console.table(encoded);

Table shows only the encoded characters. Empty cells mean that the original and the encoded characters are the same.

Just to be extra, I'm adding another table for urlencode() vs rawurlencode(). The only difference seems to be the encoding of space character.

<script>
<?php
$ascii = str_split(" !\"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\\]^_`abcdefghijklmnopqrstuvwxyz{|}~", 1);
$encoded = [];
foreach ($ascii as $char) {
    $obj = ["char" => $char];
    if ($char != urlencode($char))
        $obj["urlencode"] = urlencode($char);
    if ($char != rawurlencode($char))
        $obj["rawurlencode"] = rawurlencode($char);
    if (isset($obj["rawurlencode"]) || isset($obj["rawurlencode"]))
        $encoded[] = $obj;
}
echo "var encoded = " . json_encode($encoded) . ";";
?>
console.table(encoded);
</script>

You can use the condition if x is not null then.... It's not a function. There's also the NVL() function, a good example of usage here: NVL function ref.

findAny & orElse

By using findAny() and orElse():

Person matchingObject = objects.stream().
filter(p -> p.email().equals("testemail")).
findAny().orElse(null);

Stops looking after finding an occurrence.

findAny

Optional<T> findAny()

Returns an Optional describing some element of the stream, or an empty Optional if the stream is empty. This is a short-circuiting terminal operation. The behavior of this operation is explicitly nondeterministic; it is free to select any element in the stream. This is to allow for maximal performance in parallel operations; the cost is that multiple invocations on the same source may not return the same result. (If a stable result is desired, use findFirst() instead.)

I want to point a different view on this general naming convention, e.g.:

see java.util.Set: boolean add?(E e)

where the rationale is:

do some processing then report whether it succeeded or not.

While the return is indeed a boolean the method's name should point the processing to complete instead of the result type (boolean for this example).

Your createFreshSnapshot example seems for me more related to this point of view because seems to mean this: create a fresh-snapshot then report whether the create-operation succeeded. Considering this reasoning the name createFreshSnapshot seems to be the best one for your situation.

In Java, the single operators &, |, ^, ! depend on the operands. If both operands are ints, then a bitwise operation is performed. If both are booleans, a "logical" operation is performed.

If both operands mismatch, a compile time error is thrown.

The double operators &&, || behave similarly to their single counterparts, but both operands must be conditional expressions, for example:

if (( a < 0 ) && ( b < 0 )) { ... } or similarly, if (( a < 0 ) || ( b < 0 )) { ... }

Solution: change the ReuseStrategy to never

Since this problem is very complex and there are so many different factors which can fail I was happy to find this solution in another post: How to solve org.apache.http.NoHttpResponseException

Never reuse connections: configure in org.apache.http.impl.client.AbstractHttpClient:

httpClient.setReuseStrategy(new NoConnectionReuseStrategy());

The same can be configured on a org.apache.http.impl.client.HttpClientBuilder builder:

builder.setConnectionReuseStrategy(new NoConnectionReuseStrategy());

Based on the accepted answer, if an index corresponding to each column is also desired:

for i, column in enumerate(df):
    print i, df[column]

The above df[column] type is Series, which can simply be converted into numpy ndarrays:

for i, column in enumerate(df):
    print i, np.asarray(df[column])

Try this:

   AlertDialog.Builder builder = new AlertDialog.Builder(this);
   AlertDialog OptionDialog = builder.create();
  background.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            SetBackground();
       OptionDialog .dismiss();
        }
    });

The left inset is caused by Toolbar's contentInsetStart which by default is 16dp.

Change this to align to the keyline.

Update for support library v24.0.0:

To match the Material Design spec there's an additional attribute contentInsetStartWithNavigation which by default is 16dp. Change this if you also have a navigation icon.

It turned out that this is part of a new Material Design Specification introduced in version 24 of Design library.

https://material.google.com/patterns/navigation.html

However, it is possible to remove the extra space by adding the following property to Toolbar widget.

app:contentInsetStartWithNavigation="0dp"

It seems Subclipse only allows you to add a top-level folder to ignore list and not any sub folders under it. Not sure why it works this way. However, I found out by trial and error that if you directly add a sub-folder to version control, then it will allow you to add another folder at the same level to the ignore list.

For example, refer fig above, when I wanted to ignore the webapp folder without adding src, subclipse was not allowing me to do so. But when I added the java folder to version control, the "add to svn:ignore..." was enabled for webapp.

Of course, "Fagner Antunes Dornelles" is correct in its answer. But it seems to me that it is worth checking the registry branch itself in addition, or be sure of the part that is exactly there.

For example ("dirty hack"), i need to establish trust in the RMS infrastructure, otherwise when i open Word or Excel documents, i will be prompted for "Active Directory Rights Management Services". Here's how i can add remote trust to me servers in the enterprise infrastructure.

foreach (var strServer in listServer)
{
    try
    {
        RegistryKey regCurrentUser = Registry.CurrentUser.OpenSubKey($"Software\\Classes\\Local Settings\\Software\\Microsoft\\MSIPC\\{strServer}", false);
        if (regCurrentUser == null)
            throw new ApplicationException("Not found registry SubKey ...");
        if (regCurrentUser.GetValueNames().Contains("UserConsent") == false)
            throw new ApplicationException("Not found value in SubKey ...");
    }
    catch (ApplicationException appEx)
    {
        Console.WriteLine(appEx);
        try
        {
            RegistryKey regCurrentUser = Registry.CurrentUser.OpenSubKey($"Software\\Classes\\Local Settings\\Software\\Microsoft\\MSIPC", true);
            RegistryKey newKey = regCurrentUser.CreateSubKey(strServer, true);
            newKey.SetValue("UserConsent", 1, RegistryValueKind.DWord);
        }
        catch(Exception ex)
        {
            Console.WriteLine($"{ex} Pipec kakoito ...");
        }
    }
}

You can also use parse_url() function from Locutus project (former php.js).

Code:

parse_url('http://username:password@hostname/path?arg=value#anchor');

Result:

{
  scheme: 'http',
  host: 'hostname',
  user: 'username',
  pass: 'password',
  path: '/path',
  query: 'arg=value',
  fragment: 'anchor'
}

Use:

git reset HEAD filepath

For example:

git reset HEAD om211/src/META-INF/persistence.xml

After installing the Office PIA (primary interop assemblies), add a reference to your project -> its on the .NET tab - component name "Office"

Suppose you have a tree like this:

dd2e86 - 946992 - 9143a9 - a6fd86 - 5a6057 [master]

First, checkout a temp branch:

git checkout -b temp

On temp branch, reset --hard to a commit that you want to change its message (for example, that commit is 946992):

git reset --hard 946992

Use amend to change the message:

git commit --amend -m "<new_message>"

After that the tree will look like this:

dd2e86 - 946992 - 9143a9 - a6fd86 - 5a6057 [master]
           \
            b886a0 [temp]

Then, cherry-pick all the commit that is ahead of 946992 from master to temp and commit them, use amend if you want to change their messages as well:

git cherry-pick 9143a9
git commit --amend -m "<new_message>
...
git cherry-pick 5a6057
git commit --amend -m "<new_message>

The tree now looks like this:

dd2e86 - 946992 - 9143a9 - a6fd86 - 5a6057 [master]
               \
                b886a0 - 41ab2c - 6c2a3s - 7c88c9 [temp]

Now force push the temp branch to remote:

git push --force origin temp:master

The final step, delete branch master on local, git fetch origin to pull branch master from the server, then switch to branch master and delete branch temp.

Now both your local and remote will have all the messages updated.

Had the same exception. In my case, I had to run Command Prompt with Administrator Rights.

From the Start Menu, right click on Command Prompt, select "Run as administrator".

Give the container class

.container{
    height: 100vh;
    width: 100vw;
    display: flex;
}

Give the div that's inside the container:

align-content: center;

All the content inside this div will show up in the middle of the page.

Parsing is the division of text in to a set of parts or tokens.

You can take all your "selected values" by the name of the checkboxes and present them in a sting separated by ",".

A nice way to do this is to use jQuery's $.map():

var selected_val = $.map($("input[name='d_name']:checked"), function(a)
    {
        return a.value;
    }).join(',');

alert(selected_val);

Although you can "replace" a button with an image using the following CSS...

.className {
   background: url(http://sstatic.net/so/img/logo.png) no-repeat 0 0;
   border: 0;
   height: 61px;
   width: 250px
}

...the best thing to do here is use an ImageButton control because it will allow you to use alternate text (for accessibility).

In recent browsers you can use:

Object.keys(obj.Data).length

See MDN

For older browsers, use the for-in loop in Michael Geary's answer.

You need to add z-index to the divs, with a positive number for the top div and negative for the div below

I've installed and use VB6 for legacy projects many times on Windows 7.

What I have done and never came across any issues, is to install VB6, ignore the errors and then proceed to install the latest service pack, currently SP6.

Download here: http://www.microsoft.com/en-us/download/details.aspx?id=5721

Bonus: Also once you install it and realize that scrolling doesn't work, use the below: http://www.joebott.com/vb6scrollwheel.htm

you must use import android.support.v7.app.ActionBarDrawerToggle;

and use the constructor

public CustomActionBarDrawerToggle(Activity mActivity,DrawerLayout mDrawerLayout)
{
    super(mActivity, mDrawerLayout, R.string.ns_menu_open, R.string.ns_menu_close);
}

and if the drawer toggle button becomes dark then you must use the supportActionBar provided in the support library.

You can implement supportActionbar from this link: http://developer.android.com/training/basics/actionbar/setting-up.html

You can refer to the following code (of course you can customize to get more details of the network response):

try {
    RequestQueue requestQueue = Volley.newRequestQueue(this);
    String URL = "http://...";
    JSONObject jsonBody = new JSONObject();
    jsonBody.put("Title", "Android Volley Demo");
    jsonBody.put("Author", "BNK");
    final String requestBody = jsonBody.toString();

    StringRequest stringRequest = new StringRequest(Request.Method.POST, URL, new Response.Listener<String>() {
        @Override
        public void onResponse(String response) {
            Log.i("VOLLEY", response);
        }
    }, new Response.ErrorListener() {
        @Override

        }
    }) {
        @Override
        public String getBodyContentType() {
            return "application/json; charset=utf-8";
        }

        @Override
        public byte[] getBody() throws AuthFailureError {

                // can get more details such as response.headers
            }
            return Response.success(responseString, HttpHeaderParser.parseCacheHeaders(response));
        }
    };

    requestQueue.add(stringRequest);

df.groupby('Company Name').agg({'Organisation name':'count','Amount':'sum'})\
    .apply(lambda x: x.sort_values(['count','sum'], ascending=False))

To answer a modulo x % y, you ask two questions:

A- How many times y goes in x without remainder ? For 2%4 that's 0.

B- How much do you need to add to get from that back to x ? To get from 0 back to 2 you'll need 2-0, i.e. 2.

These can be summed up in one question like so: How much will you need to add to the integer-ish result of the division of x by y, to get back at x?

By integer-ish it is meant only whole numbers and not fractions whatsoever are of interest.

A fractional division remainder (e.g. .283849) is not of interest in modulo because modulo only deals with integer numbers.

The asterisk (*) means "zero or more of the previous item".

If you want to match any single character use

sed -i 's/string-./string-0/g' file.txt

If you want to match any string (i.e. any single character zero or more times) use

sed -i 's/string-.*/string-0/g' file.txt

As mklement0 points out, a feature for listing all Makefile targets is missing from GNU-make, and his answer and others provides ways to do this.

However, the original post also mentions rake, whose tasks switch does something slightly different than just listing all tasks in the rakefile. Rake will only give you a list of tasks that have associated descriptions. Tasks without descriptions will not be listed. This gives the author the ability to both provide customized help descriptions and also omit help for certain targets.

If you want to emulate rake's behavior, where you provide descriptions for each target, there is a simple technique for doing this: embed descriptions in comments for each target you want listed.

You can either put the description next to the target or, as I often do, next to a PHONY specification above the target, like this:

.PHONY: target1 # Target 1 help text
target1: deps
    [... target 1 build commands]

.PHONY: target2 # Target 2 help text

.PHONY: help # Generate list of targets with descriptions                                                                
help:                                                                                                                    
    @grep '^.PHONY: .* #' Makefile | sed 's/\.PHONY: \(.*\) # \(.*\)/\1 \2/' | expand -t20

Which will yield

$ make help
target1             Target 1 help text
target2             Target 2 help text

...
help                Generate list of targets with descriptions

You can also find a short code example in this gist and here too.

Again, this does not solve the problem of listing all the targets in a Makefile. For example, if you have a big Makefile that was maybe generated or that someone else wrote, and you want a quick way to list its targets without digging through it, this won't help.

However, if you are writing a Makefile, and you want a way to generate help text in a consistent, self-documenting way, this technique may be useful.

Running the risk of getting another Necromancer badge, I would like to add one very good use for uintptr_t (or even intptr_t) and that is writing testable embedded code. I write mostly embedded code targeted at various arm and currently tensilica processors. These have various native bus width and the tensilica is actually a Harvard architecture with separate code and data buses that can be different widths. I use a test driven development style for much of my code which means I do unit tests for all the code units I write. Unit testing on actual target hardware is a hassle so I typically write everything on an Intel based PC either in Windows or Linux using Ceedling and GCC. That being said, a lot of embedded code involves bit twiddling and address manipulations. Most of my Intel machines are 64 bit. So if you are going to test address manipulation code you need a generalized object to do math on. Thus the uintptr_t give you a machine independent way of debugging your code before you try deploying to target hardware. Another issue is for the some machines or even memory models on some compilers, function pointers and data pointers are different widths. On those machines the compiler may not even allow casting between the two classes, but uintptr_t should be able to hold either. -- Edit -- Was pointed out by @chux, this is not part of the standard and functions are not objects in C. However it usually works and since many people don't even know about these types I usually leave a comment explaining the trickery. Other searches in SO on uintptr_t will provide further explanation. Also we do things in unit testing that we would never do in production because breaking things is good.

There's also an open source project (a collection of cross platform [Linux, Mac, Win] scripts) that does all the nitty-gritty details of the repository management with a handful (3-4) of commands.

https://github.com/karalabe/gitbox/wiki

Sample usage is:

$ gitbox create myapp
Creating empty repository...
Initializing new repository...
Repository successfully created.

$ gitbox clone myapp
Cloning repository...
Repository successfully cloned.

After which normal git usage:

$ echo “Some change” > somefile.txt
$ git add somefile.txt
$ git commit –m “Created some file”
$ git push

Check the project wiki and the manuals for full command reference and tutorials.

I assume that you're writing to the file, then close it (so the user can open it in Excel), and then, before re-opening it for append/write operations, you want to check that the file isn't still open in Excel?

This is how you could do that:

while True:   # repeat until the try statement succeeds
    try:
        myfile = open("myfile.csv", "r+") # or "a+", whatever you need
        break                             # exit the loop
    except IOError:
        input("Could not open file! Please close Excel. Press Enter to retry.")
        # restart the loop

with myfile:
    do_stuff()

The query() function returns an object, you'll want fetch a record from what's returned from that function. Look at the examples on this page to learn how to print data from mysql

Firstly, please confirm mysql-server is installed. I have the same error when mysql-server is installed but corrupted somehow. I do the trick by uninstall mysql completely and reinstall it.

sudo apt-get remove --purge mysql*
sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get install mysql-server mysql-client

As far as I know its not possible with javascript.

What you can do for every result create a screenshot, save it somewhere and point the user when clicked on save result. (I guess no of result is only 10 so not a big deal to create 10 jpeg image of results)

Update 2020: It's been 7 years since I wrote this answer. It still seems to be getting a lot of attention. In 2013 Newtonsoft Json.Net was THE answer to this problem. Now it's still a good answer to this problem but it's no longer the the only viable option. To add some up-to-date caveats to this answer:

• .Net Core now has the spookily similar System.Text.Json serialiser (see below)
• The days of the JavaScriptSerializer have thankfully passed and this class isn't even in .Net Core. This invalidates a lot of the comparisons ran by Newtonsoft.
• It's also recently come to my attention, via some vulnerability scanning software we use in work that Json.Net hasn't had an update in some time. Updates in 2020 have dried up and the latest version, 12.0.3, is over a year old.
• The speed tests quoted below are comparing an older version of Json.Nt (version 6.0 and like I said the latest is 12.0.3) with an outdated .Net Framework serialiser.

Are Json.Net's days numbered? It's still used a LOT and it's still used by MS librarties. So probably not. But this does feel like the beginning of the end for this library that may well of just run it's course.

Update since .Net Core 3.0

A new kid on the block since writing this is System.Text.Json which has been added to .Net Core 3.0. Microsoft makes several claims to how this is, now, better than Newtonsoft. Including that it is faster than Newtonsoft. as below, I'd advise you to test this yourself .

I would recommend Json.Net, see example below:

List<data> _data = new List<data>();
_data.Add(new data()
{
    Id = 1,
    SSN = 2,
    Message = "A Message"
});

string json = JsonConvert.SerializeObject(_data.ToArray());

//write string to file
System.IO.File.WriteAllText(@"D:\path.txt", json);

Or the slightly more efficient version of the above code (doesn't use a string as a buffer):

//open file stream
using (StreamWriter file = File.CreateText(@"D:\path.txt"))
{
     JsonSerializer serializer = new JsonSerializer();
     //serialize object directly into file stream
     serializer.Serialize(file, _data);
}

Documentation: Serialize JSON to a file

Why? Here's a feature comparison between common serialisers as well as benchmark tests .

Below is a graph of performance taken from the linked article:

This separate post, states that:

Json.NET has always been memory efficient, streaming the reading and writing large documents rather than loading them entirely into memory, but I was able to find a couple of key places where object allocations could be reduced...... (now) Json.Net (6.0) allocates 8 times less memory than JavaScriptSerializer

^{_{Benchmarks appear to be Json.Net 5, the current version (on writing) is 10. What version of standard .Net serialisers used is not mentioned}}

^{_{These tests are obviously from the developers who maintain the library. I have not verified their claims. If in doubt test them yourself.}}

just put the autoplay="false" on source tag.. :)

EncryptionThe Purpose of encryption is to transform data in order to keep it secret E.g (Sending someone a secret text that they only should able to read,sending passwords through Internet).

Instead of focusing the usability the goal is to ensure the data send can be sent secretly and it can only seen by the user whom you sent.

It Encrypts the data into another format of transforming it into unique pattern it can be encrypt with the secret key and those users who having the secret key can able to see the message by reversible the process. E.g(AES,BLOWFISH,RSA)

The encryption may simply look like this FhQp6U4N28GITVGjdt37hZN

Hashing In technically we can say it as takes a arbitary input and produced a fixed length string.

Most important thing in these is you can't go from the output to the input.It produces the strong output that the given information has not been modified. The process is to take a input and hash it and then send with the sender's private key once the receiver received they can validate it with sender's public key.

If the hash is wrong and did't match with hash we can't see any of the information. E.g(MD5,SHA.....)

To click on a piece of the text (not the whole TextView), you can use Html or Linkify (both create links that open urls, though, not a callback in the app).

Linkify

Use a string resource like:

<string name="links">Here is a link: http://www.stackoverflow.com</string>

Then in a textview:

TextView textView = ...
textView.setText(R.string.links);
Linkify.addLinks(textView, Linkify.ALL);

Html

Using Html.fromHtml:

<string name="html">Here you can put html &lt;a href="http://www.stackoverflow.com"&gt;Link!&lt;/&gt;</string>

Then in your textview:

textView.setText(Html.fromHtml(getString(R.string.html)));

insert into OPT (email, campaign_id) 
select '[email protected]',100
from dual
where not exists(select * 
                 from OPT 
                 where (email ='[email protected]' and campaign_id =100));

Right click on the project in Eclipse -> Android tools -> Export without signed key. Connect your device. Mount it by sdk/tools.

The solutions above are great for interactive use, where you can eyeball the result and weed out false positives that way.

False positives can occur if the executable itself happens to match, or any arguments that are not script names match - the likelihood is greater with scripts that have no filename extensions.

Here's a more robust solution for scripting, using a shell function:

getscript() {
  pgrep -lf ".[ /]$1( |\$)"
}

Example use:

# List instance(s) of script "aa.sh" that are running.
getscript "aa.sh"  # -> (e.g.): 96112 bash /Users/jdoe/aa.sh

# Use in a test:
if getscript "aa.sh" >/dev/null; then
  echo RUNNING
fi

• Matching is case-sensitive (on macOS, you could add -i to the pgrep call to make it case-insensitive; on Linux, that is not an option.)
• The getscript function also works with full or partial paths that include the filename component; partial paths must not start with / and each component specified must be complete. The "fuller" the path specified, the lower the risk of false positives. Caveat: path matching will only work if the script was invoked with a path - this is generally true for scripts in the $PATH that are invoked directly.
• Even this function cannot rule out all false positives, as paths can have embedded spaces, yet neither ps nor pgrep reflect the original quoting applied to the command line. All the function guarantees is that any match is not the first token (which is the interpreter), and that it occurs as a separate word, optionally preceded by a path.
• Another approach to minimizing the risk of false positives could be to match the executable name (i.e., interpreter, such as bash) as well - assuming it is known; e.g.

# List instance(s) of a running *bash* script.
getbashscript() {
  pgrep -lf "(^|/)bash( | .*/)$1( |\$)"
}

If you're willing to make further assumptions - such as script-interpreter paths never containing embedded spaces - the regexes could be made more restrictive and thus further reduce the risk of false positives.

add and remove methods are easier to use. They update the data in the list and call notifyDataSetChanged in background.

Sample code:

adapter.add("your object");
adapter.remove("your object");

The third template parameter must be a class who has operator()(Node,Node) overloaded. So you will have to create a class this way:

class ComparisonClass {
    bool operator() (Node, Node) {
        //comparison code here
    }
};

And then you will use this class as the third template parameter like this:

priority_queue<Node, vector<Node>, ComparisonClass> q;

Seems based on benchmarks at JSPerf that using += is the fastest method, though not necessarily in every browser.

For building strings in the DOM, it seems to be better to concatenate the string first and then add to the DOM, rather then iteratively add it to the dom. You should benchmark your own case though.

(Thanks @zAlbee for correction)

To make it visible between the instances of T1 and T2 you could make the two classes contain a reference to an object that contains the variable.

If the variable is to be modified when the threads are running, you need to consider synchronization. The best approach depends on your exact requirements, but the main options are as follows:

• make the variable volatile;
• turn it into an AtomicBoolean;
• use full-blown synchronization around code that uses it.

By using the Robot class in Java:

import java.awt.Robot;
import java.awt.event.KeyEvent;

public class Test1
{
    public static void main(String[] args) throws Exception
    {
        WebDriver d1 = new FirefoxDriver();
        d1.navigate().to("https://www.youtube.com/");
        Thread.sleep(3000);
        Robot rb = new Robot();
        rb.keyPress(KeyEvent.VK_TAB);
        rb.keyRelease(KeyEvent.VK_TAB);
        rb.keyPress(KeyEvent.VK_TAB);
        rb.keyRelease(KeyEvent.VK_TAB);

        // Perform [Ctrl+A] Operation - it works
        rb.keyPress(KeyEvent.VK_CONTROL);
        rb.keyPress(KeyEvent.VK_A);

        // It needs to release key after pressing
        rb.keyRelease(KeyEvent.VK_A);
        rb.keyRelease(KeyEvent.VK_CONTROL);
        Thread.sleep(3000);
    }
}

Within your <jre location>\lib\security\java.policy try adding:

grant { permission java.security.AllPermission; };

And see if it allows you. If so, you will have to add more granular permissions.

This problem has hounded me for some days now, so on finding the answer that affirmatively works with tvanfosson's answer above, I thought it would be worthwhile to emphasize the core part of the answer, and address some related catch ya's.

The core answer is this, sweet and simple:

filterContext.Result = new HttpUnauthorizedResult();

In my case I inherit from a base controller, so in each controller that inherits from it I override OnAuthorize:

protected override void OnAuthorization(AuthorizationContext filterContext)
{
    base.OnAuthorization(filterContext);
    YourAuth(filterContext); // do your own authorization logic here
}

The problem was that in 'YourAuth', I tried two things that I thought would not only work, but would also immediately terminate the request. Well, that is not how it works. So first, the two things that DO NOT work, unexpectedly:

filterContext.RequestContext.HttpContext.Response.Redirect("/Login"); // doesn't work!
FormsAuthentication.RedirectToLoginPage(); // doesn't work!

Not only do those not work, they don't end the request either. Which means the following:

if (!success) {
    filterContext.Result = new HttpUnauthorizedResult();
}
DoMoreStuffNowThatYouThinkYourAuthorized();

Well, even with the correct answer above, the flow of logic still continues! You will still hit DoMoreStuff... within OnAuthorize. So keep that in mind (DoMore... should be in an else therefore).

But with the correct answer, while OnAuthorize flow of logic continues till the end still, after that you really do get what you expect: a redirect to your login page (if you have one set in Forms auth in your webconfig).

But unexpectedly, 1) Response.Redirect("/Login") does not work: the Action method still gets called, and 2) FormsAuthentication.RedirectToLoginPage(); does the same thing: the Action method still gets called!

Which seems totally wrong to me, particularly with the latter: who would have thought that FormsAuthentication.RedirectToLoginPage does not end the request, or do the equivalant above of what filterContext.Result = new HttpUnauthorizedResult() does?

A segementation fault is an internal error in php (or, less likely, apache). Oftentimes, the segmentation fault is caused by one of the newer and lesser-tested php modules such as imagemagick or subversion.

Try disabling all non-essential modules (in php.ini), and then re-enabling them one-by-one until the error occurs. You may also want to update php and apache.

If that doesn't help, you should report a php bug.

The case values are just codeless "goto" points that can share the same entry point:

case text1:
case text4: 
    //blah
    break;

Note that the braces are redundant.

Use a binding for the value in your template.

value="{{ option.id }}"

should be

[value]="option.id"

And in your selected value use ngModel instead of value.

<mat-select [(value)]="selected2">

should be

<mat-select [(ngModel)]="selected2">

Complete code:

<div>
  <mat-select [(ngModel)]="selected2">
    <mat-option *ngFor="let option of options2" [value]="option.id">{{ option.name }}</mat-option>
  </mat-select>
</div>

On a side note as of version 2.0.0-beta.12 the material select now accepts a mat-form-field element as the parent element so it is consistent with the other material input controls. Replace the div element with mat-form-field element after you upgrade.

<mat-form-field>
  <mat-select [(ngModel)]="selected2">
    <mat-option *ngFor="let option of options2" [value]="option.id">{{ option.name }}</mat-option>
  </mat-select>
</mat-form-field>

xmltodict (full disclosure: I wrote it) does exactly that:

xmltodict.parse("""
<?xml version="1.0" ?>
<person>
  <name>john</name>
  <age>20</age>
</person>""")
# {u'person': {u'age': u'20', u'name': u'john'}}

I suspect that the xcopy command is the magic bullet you're looking for.

It can copy files, directories, and even entire drives while preserving the original directory hierarchy. There are also a handful of additional options available, compared to the basic copy command.

Check out the documentation here.

If your batch file only needs to run on Windows Vista or later, you can use robocopy instead, which is an even more powerful tool than xcopy, and is now built into the operating system. It's documentation is available here.

I know its been a while since the original post but I like using CTE's and this worked for me:

WITH cte_table_a
AS
(
    SELECT [id] [id]
    , MAX([value]) [value]
    FROM table_a
    GROUP BY [id]
)
UPDATE table_b
SET table_b.code = CASE WHEN cte_table_a.[value] IS NOT NULL THEN cte_table_a.[value] ELSE 124 END
FROM table_b
LEFT OUTER JOIN  cte_table_a
ON table_b.id = cte_table_a.id

i also had this issue- very annoying and haven't found a satisfactory sql answer myself yet (aside from long-winded ones involving creating temp tables etc.) and i didn't have time to explore it to the conclusion i'd have liked.

In the end just used SQL Server Management Studio to do it by selecting the table, right-clicking on the column and hitting rename. simples!

obviously i'd rather know how to do it without a gui but sometimes you've just gotta get sh** done!

You have enabled CORS and enabled Access-Control-Allow-Origin : * in the server.If still you get GET method working and POST method is not working then it might be because of the problem of Content-Type and data problem.

First AngularJS transmits data using Content-Type: application/json which is not serialized natively by some of the web servers (notably PHP). For them we have to transmit the data as Content-Type: x-www-form-urlencoded

Example :-

        $scope.formLoginPost = function () {
            $http({
                url: url,
                method: "POST",
                data: $.param({ 'username': $scope.username, 'Password': $scope.Password }),
                headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
            }).then(function (response) {
                // success
                console.log('success');
                console.log("then : " + JSON.stringify(response));
            }, function (response) { // optional
                // failed
                console.log('failed');
                console.log(JSON.stringify(response));
            });
        };

Note : I am using $.params to serialize the data to use Content-Type: x-www-form-urlencoded. Alternatively you can use the following javascript function

function params(obj){
    var str = "";
    for (var key in obj) {
        if (str != "") {
            str += "&";
        }
        str += key + "=" + encodeURIComponent(obj[key]);
    }
    return str;
}

and use params({ 'username': $scope.username, 'Password': $scope.Password }) to serialize it as the Content-Type: x-www-form-urlencoded requests only gets the POST data in username=john&Password=12345 form.

What you are looking for is merging.

git merge master

With pull you fetch changes from a remote repository and merge them into the current branch.

Just use an ALTER TABLE... MODIFY... query and add NOT NULL into your existing column definition. For example:

ALTER TABLE Person MODIFY P_Id INT(11) NOT NULL;

A word of caution: you need to specify the full column definition again when using a MODIFY query. If your column has, for example, a DEFAULT value, or a column comment, you need to specify it in the MODIFY statement along with the data type and the NOT NULL, or it will be lost. The safest practice to guard against such mishaps is to copy the column definition from the output of a SHOW CREATE TABLE YourTable query, modify it to include the NOT NULL constraint, and paste it into your ALTER TABLE... MODIFY... query.

To not worry about using milliseconds or seconds just do:

    public static DateTime _ToDateTime(this long unixEpochTime)
    {
        DateTime epoch = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);
        var date = epoch.AddMilliseconds(unixEpochTime);

        if (date.Year > 1972)
            return date;

        return epoch.AddSeconds(unixEpochTime);
    }

If epoch time is in seconds then there is no way you can pass year 1972 adding milliseconds.

By using the wordwrap function. It splits the texts in multiple lines such that the maximum width is the one you specified, breaking at word boundaries. After splitting, you simply take the first line:

substr($string, 0, strpos(wordwrap($string, $your_desired_width), "\n"));

One thing this oneliner doesn't handle is the case when the text itself is shorter than the desired width. To handle this edge-case, one should do something like:

if (strlen($string) > $your_desired_width) 
{
    $string = wordwrap($string, $your_desired_width);
    $string = substr($string, 0, strpos($string, "\n"));
}

The above solution has the problem of prematurely cutting the text if it contains a newline before the actual cutpoint. Here a version which solves this problem:

function tokenTruncate($string, $your_desired_width) {
  $parts = preg_split('/([\s\n\r]+)/', $string, null, PREG_SPLIT_DELIM_CAPTURE);
  $parts_count = count($parts);

  $length = 0;
  $last_part = 0;
  for (; $last_part < $parts_count; ++$last_part) {
    $length += strlen($parts[$last_part]);
    if ($length > $your_desired_width) { break; }
  }

  return implode(array_slice($parts, 0, $last_part));
}

Also, here is the PHPUnit testclass used to test the implementation:

class TokenTruncateTest extends PHPUnit_Framework_TestCase {
  public function testBasic() {
    $this->assertEquals("1 3 5 7 9 ",
      tokenTruncate("1 3 5 7 9 11 14", 10));
  }

  public function testEmptyString() {
    $this->assertEquals("",
      tokenTruncate("", 10));
  }

  public function testShortString() {
    $this->assertEquals("1 3",
      tokenTruncate("1 3", 10));
  }

  public function testStringTooLong() {
    $this->assertEquals("",
      tokenTruncate("toooooooooooolooooong", 10));
  }

  public function testContainingNewline() {
    $this->assertEquals("1 3\n5 7 9 ",
      tokenTruncate("1 3\n5 7 9 11 14", 10));
  }
}

EDIT :

Special UTF8 characters like 'à' are not handled. Add 'u' at the end of the REGEX to handle it:

$parts = preg_split('/([\s\n\r]+)/u', $string, null, PREG_SPLIT_DELIM_CAPTURE);

location.reload();

See this MDN page for more information.

If you are refreshing after an onclick then you'll need to return false directly after

location.reload();
return false;

The reason is that your rule

%.o: %.cpp
       ...

expects the .cpp file to reside in the same directory as the .o your building. Since test.exe in your case depends on build/widgets/apple.o (etc), make is expecting apple.cpp to be build/widgets/apple.cpp.

You can use VPATH to resolve this:

VPATH = src/widgets

BUILDDIR = build/widgets

$(BUILDDIR)/%.o: %.cpp
      ...

When attempting to build "build/widgets/apple.o", make will search for apple.cpp in VPATH. Note that the build rule has to use special variables in order to access the actual filename make finds:

$(BUILDDIR)/%.o: %.cpp
        $(CC) $< -o $@

Where "$<" expands to the path where make located the first dependency.

Also note that this will build all the .o files in build/widgets. If you want to build the binaries in different directories, you can do something like

build/widgets/%.o: %.cpp
        ....

build/ui/%.o: %.cpp
        ....

build/tests/%.o: %.cpp
        ....

I would recommend that you use "canned command sequences" in order to avoid repeating the actual compiler build rule:

define cc-command
$(CC) $(CFLAGS) $< -o $@
endef

You can then have multiple rules like this:

build1/foo.o build1/bar.o: %.o: %.cpp
    $(cc-command)

build2/frotz.o build2/fie.o: %.o: %.cpp
    $(cc-command)

You can set the following environment variable:

PIP_TARGET=/path/to/pip/dir

https://pip.pypa.io/en/stable/user_guide/#environment-variables

Try this...

 var start = new Date(document.getElementById('Stardate').value);
 var y = start.getFullYear();

Splits an array in multiple arrays with a fixed maximum size.

public static <T extends Object> List<T[]> splitArray(T[] array, int max){

  int x = array.length / max;
  int r = (array.length % max); // remainder

  int lower = 0;
  int upper = 0;

  List<T[]> list = new ArrayList<T[]>();

  int i=0;

  for(i=0; i<x; i++){

    upper += max;

    list.add(Arrays.copyOfRange(array, lower, upper));

    lower = upper;
  }

  if(r > 0){

    list.add(Arrays.copyOfRange(array, lower, (lower + r)));

  }

  return list;
}

Example - an Array of 11 shall be splitted into multiple Arrays not exceeding a size of 5:

// create and populate an array
Integer[] arr = new Integer[11];

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

// split into pieces with a max. size of 5
List<Integer[]> list = ArrayUtil.splitArray(arr, 5);

// check
for(int i=0; i<list.size(); i++){

  System.out.println("Array " + i);

  for(int j=0; j<list.get(i).length; j++){
    System.out.println("  " + list.get(i)[j]);
  }
}

Output:

Array 0
  0
  1
  2

Pre C# 6.0 solution

You can use this to get a name of any provided member:

public static class MemberInfoGetting
{
    public static string GetMemberName<T>(Expression<Func<T>> memberExpression)
    {
        MemberExpression expressionBody = (MemberExpression)memberExpression.Body;
        return expressionBody.Member.Name;
    }
}

To get name of a variable:

string testVariable = "value";
string nameOfTestVariable = MemberInfoGetting.GetMemberName(() => testVariable);

To get name of a parameter:

public class TestClass
{
    public void TestMethod(string param1, string param2)
    {
        string nameOfParam1 = MemberInfoGetting.GetMemberName(() => param1);
    }
}

C# 6.0 and higher solution

You can use the nameof operator for parameters, variables and properties alike:

string testVariable = "value";
string nameOfTestVariable = nameof(testVariable);

One thing you can do is get rid of all those onclick attributes and do it the right way with bootstrap. You don't need to open them manually; you can specify the trigger and even subscribe to events before the modal opens so that you can do your operations and populate data in it.

I am just going to show as a static example which you can accommodate in your real world.

On each of your <tr>'s add a data attribute for id (i.e. data-id) with the corresponding id value and specify a data-target, which is a selector you specify, so that when clicked, bootstrap will select that element as modal dialog and show it. And then you need to add another attribute data-toggle=modal to make this a trigger for modal.

  <tr data-toggle="modal" data-id="1" data-target="#orderModal">
            <td>1</td>
            <td>24234234</td>
            <td>A</td>
  </tr>
  <tr data-toggle="modal" data-id="2" data-target="#orderModal">
            <td>2</td>
            <td>24234234</td>
            <td>A</td>
        </tr>
  <tr data-toggle="modal" data-id="3" data-target="#orderModal">
            <td>3</td>
            <td>24234234</td>
            <td>A</td>
  </tr>

And now in the javascript just set up the modal just once and event listen to its events so you can do your work.

$(function(){
    $('#orderModal').modal({
        keyboard: true,
        backdrop: "static",
        show:false,

    }).on('show', function(){ //subscribe to show method
          var getIdFromRow = $(event.target).closest('tr').data('id'); //get the id from tr
        //make your ajax call populate items or what even you need
        $(this).find('#orderDetails').html($('<b> Order Id selected: ' + getIdFromRow  + '</b>'))
    });
});

Demo

Do not use inline click attributes any more. Use event bindings instead with vanilla js or using jquery.

Alternative ways here:

Demo2 or Demo3

Using C++11:

#include <map>
using namespace std;

map<int, char> m = {{1, 'a'}, {3, 'b'}, {5, 'c'}, {7, 'd'}};

Using Boost.Assign:

#include <map>
#include "boost/assign.hpp"
using namespace std;
using namespace boost::assign;

map<int, char> m = map_list_of (1, 'a') (3, 'b') (5, 'c') (7, 'd');

//String appending
#include <iostream>
using namespace std;

void stringconcat(char *str1, char *str2){
    while (*str1 != '\0'){
        str1++;
    }

    while(*str2 != '\0'){
        *str1 = *str2;
        str1++;
        str2++;
    }
}

int main() {
    char str1[100];
    cin.getline(str1, 100);  
    char str2[100];
    cin.getline(str2, 100);

    stringconcat(str1, str2);

    cout<<str1;
    getchar();
    return 0;
}

The example below seemed to work. Just setting a height on the first element

<ul class="row">
    <li class="span4" style="height: 100px"><h1>1</h1></li>
    <li class="span4"><h1>2</h1></li>
    <li class="span4"><h1>3</h1></li>
    <li class="span4"><h1>4</h1></li>
    <li class="span4"><h1>5</h1></li>
    <li class="span4"><h1>6</h1></li>
    <li class="span4"><h1>7</h1></li>
    <li class="span4"><h1>8</h1></li>
</ul>

I can't help but thinking it's the wrong use of a row though.

Use replace method of string like the following way:

String x="\"abcd";
String z=x.replace("\"", "");
System.out.println(z);

Output:

abcd

Within Crystal, you can do it by creating a formula that uses the ToNumber function. It might be a good idea to code for the possibility that the field might include non-numeric data - like so:

If NumericText ({field}) then ToNumber ({field}) else 0

Alternatively, you might find it easier to convert the field's datatype within the query used in the report.

add your script tag on the bottom of the body tag. so that script loads after html content then you won't get such error and add=

Well, actually I'll have to say David is right with his solution, but there are some topics disturbing me:

1. You should never send your model to the view => This is correct
2. If you create a ViewModel, and include the Model as member in the ViewModel, then you effectively sent your model to the View => this is BAD
3. Using dictionaries to send the options to the view => this not good style

So how can you create a better coupling?

I would use a tool like AutoMapper or ValueInjecter to map between ViewModel and Model. AutoMapper does seem to have the better syntax and feel to it, but the current version lacks a very severe topic: It is not able to perform the mapping from ViewModel to Model (under certain circumstances like flattening, etc., but this is off topic) So at present I prefer to use ValueInjecter.

So you create a ViewModel with the fields you need in the view. You add the SelectList items you need as lookups. And you add them as SelectLists already. So you can query from a LINQ enabled sourc, select the ID and text field and store it as a selectlist: You gain that you do not have to create a new type (dictionary) as lookup and you just move the new SelectList from the view to the controller.

  // StaffTypes is an IEnumerable<StaffType> from dbContext
  // viewModel is the viewModel initialized to copy content of Model Employee  
  // viewModel.StaffTypes is of type SelectList

  viewModel.StaffTypes =
    new SelectList(
        StaffTypes.OrderBy( item => item.Name )
        "StaffTypeID",
        "Type",
        viewModel.StaffTypeID
    );

In the view you just have to call

@Html.DropDownListFor( model => mode.StaffTypeID, model.StaffTypes )

Back in the post element of your method in the controller you have to take a parameter of the type of your ViewModel. You then check for validation. If the validation fails, you have to remember to re-populate the viewModel.StaffTypes SelectList, because this item will be null on entering the post function. So I tend to have those population things separated into a function. You just call back return new View(viewModel) if anything is wrong. Validation errors found by MVC3 will automatically be shown in the view.

If you have your own validation code you can add validation errors by specifying which field they belong to. Check documentation on ModelState to get info on that.

If the viewModel is valid you have to perform the next step:

If it is a create of a new item, you have to populate a model from the viewModel (best suited is ValueInjecter). Then you can add it to the EF collection of that type and commit changes.

If you have an update, you get the current db item first into a model. Then you can copy the values from the viewModel back to the model (again using ValueInjecter gets you do that very quick). After that you can SaveChanges and are done.

Feel free to ask if anything is unclear.

You are mixing the 2 different CASE syntaxes inappropriately.

Use this style (Searched)

  CASE  
  WHEN u.nnmu ='0' THEN mu.naziv_mesta
  WHEN u.nnmu ='1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

Or this style (Simple)

  CASE u.nnmu 
  WHEN '0' THEN mu.naziv_mesta
  WHEN '1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

Not This (Simple but with boolean search predicates)

  CASE u.nnmu 
  WHEN u.nnmu ='0' THEN mu.naziv_mesta
  WHEN u.nnmu ='1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

In MySQL this will end up testing whether u.nnmu is equal to the value of the boolean expression u.nnmu ='0' itself. Regardless of whether u.nnmu is 1 or 0 the result of the case expression itself will be 1

For example if nmu = '0' then (nnmu ='0') evaluates as true (1) and (nnmu ='1') evaluates as false (0). Substituting these into the case expression gives

 SELECT CASE  '0'
  WHEN 1 THEN '0'
  WHEN 0 THEN '1'
 ELSE 'GRESKA'
 END as mesto_utovara

if nmu = '1' then (nnmu ='0') evaluates as false (0) and (nnmu ='1') evaluates as true (1). Substituting these into the case expression gives

 SELECT CASE  '1'
  WHEN 0 THEN '0'
  WHEN 1 THEN '1'
 ELSE 'GRESKA'
 END as mesto_utovara

This may not be exactly what you're looking for (it's not an "easy" solution to send your Tabs to the bottom of the screen) but is nevertheless an interesting alternative solution I would like to flag to you :

ScrollableTabHost is designed to behave like TabHost, but with an additional scrollview to fit more items ...

maybe digging into this open-source project you'll find an answer to your question. If I see anything easier I'll come back to you.

I am using python3 and found out that you need to encode your string before you can pass it into stdin:

p = Popen(['grep', 'f'], stdout=PIPE, stdin=PIPE, stderr=PIPE)
out, err = p.communicate(input='one\ntwo\nthree\nfour\nfive\nsix\n'.encode())
print(out)

Be warned, each time the file is opened with this method the old data in the file is destroyed regardless of 'w+' or just 'w'.

import os

with open("file.txt", 'w+') as f:
    f.write("file is opened for business")

Other languages will use coding conventions, they just tend to be different. C# for example has probably two different styles that people tend to use, either one of the C++ methods (_variable, mVariable or other prefix such as Hungarian notation), or what I refer to as the StyleCop method.

private int privateMember;
public int PublicMember;

public int Function(int parameter)
{
  // StyleCop enforces using this. for class members.
  this.privateMember = parameter;
}

In the end, it becomes what people know, and what looks best. I personally think code is more readable without Hungarian notation, but it can become easier to find a variable with intellisense for example if the Hungarian notation is attached.

In my example above, you don't need an m prefix for member variables because prefixing your usage with this. indicates the same thing in a compiler-enforced method.

This doesn't necessarily mean the other methods are bad, people stick to what works.

try this: "select" / "active" tab

<article id="gtabs">
    <ul>
        <li><a href="#syscfg" id="tab-sys-cfg" class="tabtext">tab One</a></li>
        <li><a href="#ebsconf" id="tab-ebs-trans" class="tabtext">tab Two</a></li>
        <li><a href="#genconfig" id="tab-general-filter-config" class="tabtext">tab Three</a></li>
    </ul>

var index = $('#gtabs a[href="#general-filter-config"]').parent().index();

// `'select' does not support in jquery ui version 1.10.0

$('#gtabs').tabs('select', index);  

alternate solution: use "active":

$('#gtabs').tabs({ active: index });

Other languages have short cuts for ranges of field numbers, but not awk, you'll have to write your code as your fear ;-)

awk -F, 'BEGIN {OFS=","} { print $1, $2, $3, $4 ..... $30, $33}' infile.csv > outfile.csv

There is no direct function in awk to use field names as column specifiers.

I hope this helps.

Pure shell solution:

% rm -f error.flag; echo hello world \
| (cat || echo "First command failed: $?" >> error.flag) \
| (cat || echo "Second command failed: $?" >> error.flag) \
| (cat || echo "Third command failed: $?" >> error.flag) \
; test -s error.flag  && (echo Some command failed: ; cat error.flag)
hello world

And now with the second cat replaced by false:

% rm -f error.flag; echo hello world \
| (cat || echo "First command failed: $?" >> error.flag) \
| (false || echo "Second command failed: $?" >> error.flag) \
| (cat || echo "Third command failed: $?" >> error.flag) \
; test -s error.flag  && (echo Some command failed: ; cat error.flag)
Some command failed:
Second command failed: 1
First command failed: 141

Please note the first cat fails as well, because it's stdout gets closed on it. The order of the failed commands in the log is correct in this example, but don't rely on it.

This method allows for capturing stdout and stderr for the individual commands so you can then dump that as well into a log file if an error occurs, or just delete it if no error (like the output of dd).

You can take keys or values per index:

int value = _dict.Values.ElementAt(5);//ElementAt value should be <= _dict.Count - 1
string key = _dict.Keys.ElementAt(5);//ElementAt value should be  < =_dict.Count - 1

Specifying the columns on your query should do the trick:

select a.col1, b.col2, a.col3, b.col4, a.category_id 
from items_a a, items_b b 
where a.category_id = b.category_id

should do the trick with regards to picking the columns you want.

To get around the fact that some data is only in items_a and some data is only in items_b, you would be able to do:

select 
  coalesce(a.col1, b.col1) as col1, 
  coalesce(a.col2, b.col2) as col2,
  coalesce(a.col3, b.col3) as col3,
  a.category_id
from items_a a, items_b b
where a.category_id = b.category_id

The coalesce function will return the first non-null value, so for each row if col1 is non null, it'll use that, otherwise it'll get the value from col2, etc.

Try to change the FK to INDEX instead of UNIQUE.

I did a script to convert an existing hash encoded in base64 to decimal, it may be useful:

SELECT LOWER(SUBSTRING(CONVERT(NVARCHAR(42), CAST( [COLUMN_NAME] as XML ).value('.','varbinary(max)'), 1), 3, 40)) from TABLE

For mass assignment of values to an ActiveRecord model without saving, use either the assign_attributes or attributes= methods. These methods are available in Rails 3 and newer. However, there are minor differences and version-related gotchas to be aware of.

Both methods follow this usage:

@user.assign_attributes{ model: "Sierra", year: "2012", looks: "Sexy" }

@user.attributes = { model: "Sierra", year: "2012", looks: "Sexy" }

Note that neither method will perform validations or execute callbacks; callbacks and validation will happen when save is called.

Rails 3

attributes= differs slightly from assign_attributes in Rails 3. attributes= will check that the argument passed to it is a Hash, and returns immediately if it is not; assign_attributes has no such Hash check. See the ActiveRecord Attribute Assignment API documentation for attributes=.

The following invalid code will silently fail by simply returning without setting the attributes:

@user.attributes = [ { model: "Sierra" }, { year: "2012" }, { looks: "Sexy" } ]

attributes= will silently behave as though the assignments were made successfully, when really, they were not.

This invalid code will raise an exception when assign_attributes tries to stringify the hash keys of the enclosing array:

@user.assign_attributes([ { model: "Sierra" }, { year: "2012" }, { looks: "Sexy" } ])

assign_attributes will raise a NoMethodError exception for stringify_keys, indicating that the first argument is not a Hash. The exception itself is not very informative about the actual cause, but the fact that an exception does occur is very important.

The only difference between these cases is the method used for mass assignment: attributes= silently succeeds, and assign_attributes raises an exception to inform that an error has occurred.

These examples may seem contrived, and they are to a degree, but this type of error can easily occur when converting data from an API, or even just using a series of data transformation and forgetting to Hash[] the results of the final .map. Maintain some code 50 lines above and 3 functions removed from your attribute assignment, and you've got a recipe for failure.

The lesson with Rails 3 is this: always use assign_attributes instead of attributes=.

Rails 4

In Rails 4, attributes= is simply an alias to assign_attributes. See the ActiveRecord Attribute Assignment API documentation for attributes=.

With Rails 4, either method may be used interchangeably. Failure to pass a Hash as the first argument will result in a very helpful exception: ArgumentError: When assigning attributes, you must pass a hash as an argument.

Validations

If you're pre-flighting assignments in preparation to a save, you might be interested in validating before save, as well. You can use the valid? and invalid? methods for this. Both return boolean values. valid? returns true if the unsaved model passes all validations or false if it does not. invalid? is simply the inverse of valid?

valid? can be used like this:

@user.assign_attributes{ model: "Sierra", year: "2012", looks: "Sexy" }.valid?

This will give you the ability to handle any validations issues in advance of calling save.

Wrote a tutorial so that you can animate your activity's in and out,

Enjoy:

http://blog.blundellapps.com/animate-an-activity/

I am a fan of one-liners (where they work!). Here is what works for me:

$("#dialog").siblings(".ui-dialog-titlebar").find(".ui-dialog-titlebar-close").hide();

Check your WEB-INF/web.xml file for the servlet Mapping.

#include <chrono>
#include <iostream>

int main()
{
    std::time_t ct = std::time(0);
    char* cc = ctime(&ct);

    std::cout << cc << std::endl;
    return 0;
}

Just use:

function getData() {
    $.ajax({
        url : 'example.com',
        type: 'GET',
        success : handleData
    })
}

The success property requires only a reference to a function, and passes the data as parameter to this function.

You can access your handleData function like this because of the way handleData is declared. JavaScript will parse your code for function declarations before running it, so you'll be able to use the function in code that's before the actual declaration. This is known as hoisting.

This doesn't count for functions declared like this, though:

var myfunction = function(){}

Those are only available when the interpreter passed them.

See this question for more information about the 2 ways of declaring functions

Gem::Specification.map {|a| a.name}

However, if your app uses Bundler it will return only list of dependent local gems. To get all installed:

def all_installed_gems
   Gem::Specification.all = nil    
   all = Gem::Specification.map{|a| a.name}  
   Gem::Specification.reset
   all
end

A Python 2+3 compatible solution is:

import sys

if sys.version_info[0] >= 3:
    from urllib.request import urlretrieve
else:
    # Not Python 3 - today, it is most likely to be Python 2
    # But note that this might need an update when Python 4
    # might be around one day
    from urllib import urlretrieve

# Get file from URL like this:
urlretrieve("http://www-scf.usc.edu/~chiso/oldspice/m-b1-hello.mp3")

Try this its worked for me

SELECT * from bookedroom
    WHERE UNIX_TIMESTAMP('2020-8-07 5:31')
        between UNIX_TIMESTAMP('2020-8-07 5:30') and
        UNIX_TIMESTAMP('2020-8-09 5:30')

It's best to use whatever one reads better - there's in all practical effect 0 difference between performance.

In this case I think the last statement reads better than the first if statement, but careful not to overuse the ternary operator - sometimes it can really make things a lot less clear.

Note : This answer is now out-of-date. This changes the theme in "preview" only as @imjohnking and @john-ktejik pointed out. As @Shahzeb mentioned, theme can modified in res>values>styles

Android Studio 0.8.2 provides a slightly easier way to change the theme. In the preview window, you can select the theme of "Holo.Light.DarkActionBar" by clicking on the theme combo box just above the phone.

Or do a ctrl + click on the @style/AppTheme in the Android manifest file. It will open styles.xml file where you can change the parent attribute of the style tag.

• Theme.Holo for a "dark" theme.
• Theme.Holo.Light for a "light" theme.

When using the Support Library, you must instead use the Theme.AppCompat themes:

• Theme.AppCompat for the "dark" theme.
• Theme.AppCompat.Light for the "light" theme.
• Theme.AppCompat.Light.DarkActionBar for the light theme with a dark action bar.

From Wikipedia (granularity):

Granularity is the extent to which a system is broken down into small parts, either the system itself or its description or observation. It is the extent to which a larger entity is subdivided. For example, a yard broken into inches has finer granularity than a yard broken into feet.

Coarse-grained systems consist of fewer, larger components than fine-grained systems; a coarse-grained description of a system regards large subcomponents while a fine-grained description regards smaller components of which the larger ones are composed.

My approach to delete all rows from a table i DynamoDb is just to pull all rows out from the table, using DynamoDbs ScanAsync and then feed the result list to DynamoDbs AddDeleteItems. Below code in C# works fine for me.

        public async Task DeleteAllReadModelEntitiesInTable()
    {
        List<ReadModelEntity> readModels;

        var conditions = new List<ScanCondition>();
        readModels = await _context.ScanAsync<ReadModelEntity>(conditions).GetRemainingAsync();

        var batchWork = _context.CreateBatchWrite<ReadModelEntity>();
        batchWork.AddDeleteItems(readModels);
        await batchWork.ExecuteAsync();
    }

Note: Deleting the table and then recreating it again from the web console may cause problems if using YAML/CloudFormation to create the table.

Explanation: on what's going on here?

If we keep in mind that .replace() is equal with .remove().add() that we know by the documentation:

Replace an existing fragment that was added to a container. This is essentially the same as calling remove(Fragment) for all currently added fragments that were added with the same containerViewId and then add(int, Fragment, String) with the same arguments given here.

then what's happening is like this (I'm adding numbers to the frag to make it more clear):

// transaction.replace(R.id.detailFragment, frag1);
Transaction.remove(null).add(frag1)  // frag1 on view

// transaction.replace(R.id.detailFragment, frag2).addToBackStack(null);
Transaction.remove(frag1).add(frag2).addToBackStack(null)  // frag2 on view

// transaction.replace(R.id.detailFragment, frag3);
Transaction.remove(frag2).add(frag3)  // frag3 on view

^{(here all misleading stuff starts to happen)}

Remember that .addToBackStack() is saving only transaction not the fragment as itself! So now we have frag3 on the layout:

< press back button >
// System pops the back stack and find the following saved back entry to be reversed:
// [Transaction.remove(frag1).add(frag2)]
// so the system makes that transaction backward!!!
// tries to remove frag2 (is not there, so it ignores) and re-add(frag1)
// make notice that system doesn't realise that there's a frag3 and does nothing with it
// so it still there attached to view
Transaction.remove(null).add(frag1) //frag1, frag3 on view (OVERLAPPING)

// transaction.replace(R.id.detailFragment, frag2).addToBackStack(null);
Transaction.remove(frag3).add(frag2).addToBackStack(null)  //frag2 on view

< press back button >
// system makes saved transaction backward
Transaction.remove(frag2).add(frag3) //frag3 on view

< press back button >
// no more entries in BackStack
< app exits >

Possible solution

Consider implementing FragmentManager.BackStackChangedListener to watch for changes in the back stack and apply your logic in onBackStackChanged() methode:

• Trace a count of transaction;
• Check particular transaction by name FragmentTransaction.addToBackStack(String name);
• Etc.

I don't have IE8 to test this out, but I'm pretty sure it should work:

<div class="screen">
   <!-- code -->
   <div class="innerdiv">
      text or other content
   </div>
</div>

and the css:

.screen{
position: relative;
}
.innerdiv {
position: absolute;
bottom: 0;
right: 0;
}

This should place the .innerdiv in the bottom-right corner of the .screen class. I hope this helps :)

To Convert file path in String to NSURL, observe the following code

var filePathUrl = NSURL.fileURLWithPath(path)

FLOAT stores floating point numbers with accuracy up to eight places and has four bytes while DOUBLE stores floating point numbers with accuracy upto 18 places and has eight bytes.

Another possibility is

var res = /!id-[^!]*/.exec("!"+windowArray.join("!"));
return res && res[0].substr(1);

that IMO may make sense if you can have a special char delimiter (here i used "!"), the array is constant or mostly constant (so the join can be computed once or rarely) and the full string isn't much longer than the prefix searched for.

Real problem is when you need draw some tile/sprites intersecting/spanning two or more other tiles.

After 2 (hard) months of personal analisys of problem I finally found and implemented a "correct render drawing" for my new cocos2d-js game. Solution consists in mapping, for each tile (susceptible), which sprites are "front, back, top and behind". Once doing that you can draw them following a "recursive logic".

Was missing the use of calc in the answers, which is a cleaner solution.

#logo {
  position: absolute;
  left: calc(50% - 25px);
  height: 50px;
  width: 50px;
  background: red;
}

Works in most modern browsers: http://caniuse.com/calc

Maybe it's too soon to use it without a fallback, but I thought maybe for future visitors it would be helpful.

That's the compiler that comes with Apple's XCode tools package. They've hacked on it a little, but basically it's just g++.

You can download XCode for free (well, mostly, you do have to sign up to become an ADC member, but that's free too) here: http://developer.apple.com/technology/xcode.html

Edit 2013-01-25: This answer was correct in 2010. It needs an update.

While XCode tools still has a command-line C++ compiler, In recent versions of OS X (I think 10.7 and later) have switched to clang/llvm (mostly because Apple wants all the benefits of Open Source without having to contribute back and clang is BSD licensed). Secondly, I think all you have to do to install XCode is to download it from the App store. I'm pretty sure it's free there.

So, in order to get g++ you'll have to use something like homebrew (seemingly the current way to install Open Source software on the Mac (though homebrew has a lot of caveats surrounding installing gcc using it)), fink (basically Debian's apt system for OS X/Darwin), or MacPorts (Basically, OpenBSDs ports system for OS X/Darwin) to get it.

Fink definitely has the right packages. On 2016-12-26, it had gcc 5 and gcc 6 packages.

I'm less familiar with how MacPorts works, though some initial cursory investigation indicates they have the relevant packages as well.

Install this package in Ubuntu:

apt install sysv-rc-conf

its a substitute for chkconfig cmd.

After install run this cmd:

sysv-rc-conf --list

It'll show all services in all the runlevels. You can also run this:

sysv-rc-conf --level (runlevel number ex:1 2 3 4 5 6 )

Now you can choose which service should be active in boot time.

The / operator can be used for integer division or floating point division. You're giving it two integer operands, so it's doing integer division and then the result is being stored in a double.

i found a way to change format ,its a tricky way, i just changed the appearance of the date input fields using just a CSS code.

Facebook is using LAMP structure. Facebook’s back-end services are written in a variety of different programming languages including C++, Java, Python, and Erlang and they are used according to requirement. With LAMP Facebook uses some technologies ,to support large number of requests, like

1. Memcache - It is a memory caching system that is used to speed up dynamic database-driven websites (like Facebook) by caching data and objects in RAM to reduce reading time. Memcache is Facebook’s primary form of caching and helps alleviate the database load. Having a caching system allows Facebook to be as fast as it is at recalling your data.

2. Thrift (protocol) - It is a lightweight remote procedure call framework for scalable cross-language services development. Thrift supports C++, PHP, Python, Perl, Java, Ruby, Erlang, and others.

3. Cassandra (database) - It is a database management system designed to handle large amounts of data spread out across many servers.

4. HipHop for PHP - It is a source code transformer for PHP script code and was created to save server resources. HipHop transforms PHP source code into optimized C++. After doing this, it uses g++ to compile it to machine code.

If we go into more detail, then answer to this question go longer. We can understand more from following posts:

1. How Does Facebook Work?
2. Data Management, Facebook-style
3. Facebook database design?
4. Facebook wall's database structure
5. Facebook "like" data structure

I guess problem is in width attributes in table and td remove 'px' for example

<table border="0" cellpadding="0" cellspacing="0" width="580px" style="background-color: #0290ba;">

Should be

<table border="0" cellpadding="0" cellspacing="0" width="580" style="background-color: #0290ba;">

If you are not wanting to use async you can add .Result to force the code to execute synchronously:

private string GetResponseString(string text)
{
    var httpClient = new HttpClient();

    var parameters = new Dictionary<string, string>();
    parameters["text"] = text;

    var response = httpClient.PostAsync(BaseUri, new FormUrlEncodedContent(parameters)).Result;
    var contents = response.Content.ReadAsStringAsync().Result;

    return contents;
 }  

This was the solution for me:

-- Check how it is now
select * from patient
select * from patient_address

-- Alter your DB
alter table patient_address nocheck constraint FK__patient_a__id_no__27C3E46E
update patient 
set id_no='7008255601088'
where id_no='8008255601088'

alter table patient_address nocheck constraint FK__patient_a__id_no__27C3E46E
update patient_address 
set id_no='7008255601088'
where id_no='8008255601088'

-- Check how it is now
select * from patient
select * from patient_address

When converting datetime to integers one must keep in mind the tens, hundreds and thousands.... like "2018-11-03" must be like 20181103 in int for that you have to 2018*10000 + 100* 11 + 3

Similarly another example, "2018-11-03 10:02:05" must be like 20181103100205 in int

Explanatory Code

dt = datetime(2018,11,3,10,2,5)
print (dt)

#print (dt.timestamp()) # unix representation ... not useful when converting to int

print (dt.strftime("%Y-%m-%d"))
print (dt.year*10000 + dt.month* 100  + dt.day)
print (int(dt.strftime("%Y%m%d")))

print (dt.strftime("%Y-%m-%d %H:%M:%S"))
print (dt.year*10000000000 + dt.month* 100000000 +dt.day * 1000000 + dt.hour*10000  +  dt.minute*100 + dt.second)
print (int(dt.strftime("%Y%m%d%H%M%S")))

General Function

To avoid that doing manually use below function

def datetime_to_int(dt):
    return int(dt.strftime("%Y%m%d%H%M%S"))

After much searching a way to show a progress bar just to make the most elegant charging could not find any way that would serve my purpose. Check the actual status of the request showed demaziado complex and sometimes snippets not then worked created a very simple way but it gives me the experience seeking (or almost), follows the code:

$.ajax({
    type : 'GET',
    url : url,
    dataType: 'html',
    timeout: 10000,
    beforeSend: function(){
        $('.my-box').html('<div class="progress"><div class="progress-bar progress-bar-success progress-bar-striped active" role="progressbar" aria-valuenow="40" aria-valuemin="0" aria-valuemax="100" style="width: 0%;"></div></div>');
        $('.progress-bar').animate({width: "30%"}, 100);
    },
    success: function(data){  
        if(data == 'Unauthorized.'){
            location.href = 'logout';
        }else{
            $('.progress-bar').animate({width: "100%"}, 100);
            setTimeout(function(){
                $('.progress-bar').css({width: "100%"});
                setTimeout(function(){
                    $('.my-box').html(data);
                }, 100);
            }, 500);
        }
    },
    error: function(request, status, err) {
        alert((status == "timeout") ? "Timeout" : "error: " + request + status + err);
    }
});

Try

ChromeOptions options = new ChromeOptions();
options.addArguments("--start-fullscreen");

I stumbled on this thread while trying to find a Windows alternative for getpid() (defined in unistd.h). It turns out that including process.h does the trick. Maybe this helps people who find this thread in the future.

>>> import string
>>> string.ascii_lowercase
'abcdefghijklmnopqrstuvwxyz'

If you really need a list:

>>> list(string.ascii_lowercase)
['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z']

And to do it with range

>>> list(map(chr, range(97, 123))) #or list(map(chr, range(ord('a'), ord('z')+1)))
['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z']

Other helpful string module features:

>>> help(string) # on Python 3
....

    ascii_letters = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'
    ascii_lowercase = 'abcdefghijklmnopqrstuvwxyz'
    ascii_uppercase = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'
    digits = '0123456789'
    hexdigits = '0123456789abcdefABCDEF'
    octdigits = '01234567'
    printable = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ!"#$%&\'()*+,-./:;<=>?@[\\]^_`{|}~ \t\n\r\x0b\x0c'
    punctuation = '!"#$%&\'()*+,-./:;<=>?@[\\]^_`{|}~'
    whitespace = ' \t\n\r\x0b\x0c'

You can also get through it by the code below:

file=open(completefilepath,'r',encoding='utf8',errors="ignore")
file.read()

Maybe use a combination with strtotime() and date()?

From the man git-stash page:

The modifications stashed away by this command can be listed with git stash list, inspected with git stash show

show [<stash>]
       Show the changes recorded in the stash as a diff between the stashed state and
       its original parent. When no <stash> is given, shows the latest one. By default,
       the command shows the diffstat, but it will accept any format known to git diff
       (e.g., git stash show -p stash@{1} to view the second most recent stash in patch
       form).

To list the stashed modifications

git stash list

To show files changed in the last stash

git stash show

So, to view the content of the most recent stash, run

git stash show -p

To view the content of an arbitrary stash, run something like

git stash show -p stash@{1}

Just default the variable to the expected type:

(number=1) => ...
(number=1.0) => ...
(string='str') ...

An object file is the real output from the compilation phase. It's mostly machine code, but has info that allows a linker to see what symbols are in it as well as symbols it requires in order to work. (For reference, "symbols" are basically names of global objects, functions, etc.)

A linker takes all these object files and combines them to form one executable (assuming that it can, ie: that there aren't any duplicate or undefined symbols). A lot of compilers will do this for you (read: they run the linker on their own) if you don't tell them to "just compile" using command-line options. (-c is a common "just compile; don't link" option.)

Set Background svg with content/cart at center

.login-container {
  justify-content: center;
  align-items: center;
  display: flex;
  height: 100vh; 
  background-image: url(/assets/images/login-bg.svg);
  background-position: center;
  background-repeat: no-repeat;
  background-size: cover;
}

Use .prop instead:

$('#deliveryNext').prop('disabled')

First of all, from __future__ import print_function needs to be the first line of code in your script (aside from some exceptions mentioned below). Second of all, as other answers have said, you have to use print as a function now. That's the whole point of from __future__ import print_function; to bring the print function from Python 3 into Python 2.6+.

from __future__ import print_function

import sys, os, time

for x in range(0,10):
    print(x, sep=' ', end='')  # No need for sep here, but okay :)
    time.sleep(1)

__future__ statements need to be near the top of the file because they change fundamental things about the language, and so the compiler needs to know about them from the beginning. From the documentation:

A future statement is recognized and treated specially at compile time: Changes to the semantics of core constructs are often implemented by generating different code. It may even be the case that a new feature introduces new incompatible syntax (such as a new reserved word), in which case the compiler may need to parse the module differently. Such decisions cannot be pushed off until runtime.

The documentation also mentions that the only things that can precede a __future__ statement are the module docstring, comments, blank lines, and other future statements.

Using <summary> and <details>

Using <summary> and <details> elements is the simplest but see browser support as current IE is not supporting it. You can polyfill though (most are jQuery-based). Do note that unsupported browser will simply show the expanded version of course, so that may be acceptable in some cases.

/* Optional styling */_x000D_
summary::-webkit-details-marker {_x000D_
  color: blue;_x000D_
}_x000D_
summary:focus {_x000D_
  outline-style: none;_x000D_
}

<details>_x000D_
  <summary>Summary, caption, or legend for the content</summary>_x000D_
  Content goes here._x000D_
</details>

See also how to style the <details> element (HTML5 Doctor) (little bit tricky).

Pure CSS3

The :target selector has a pretty good browser support, and it can be used to make a single collapsible element within the frame.

.details,_x000D_
.show,_x000D_
.hide:target {_x000D_
  display: none;_x000D_
}_x000D_
.hide:target + .show,_x000D_
.hide:target ~ .details {_x000D_
  display: block;_x000D_
}

<div>_x000D_
  <a id="hide1" href="#hide1" class="hide">+ Summary goes here</a>_x000D_
  <a id="show1" href="#show1" class="show">- Summary goes here</a>_x000D_
  <div class="details">_x000D_
    Content goes here._x000D_
  </div>_x000D_
</div>_x000D_
<div>_x000D_
  <a id="hide2" href="#hide2" class="hide">+ Summary goes here</a>_x000D_
  <a id="show2" href="#show2" class="show">- Summary goes here</a>_x000D_
  <div class="details">_x000D_
    Content goes here._x000D_
  </div>_x000D_
</div>

I also went through this problem and changed that:

<application  android:debuggable="true" android:icon="@drawable/app_icon" android:label="@string/app_name" android:supportsRtl="true" android:allowBackup="false" android:fullBackupOnly="false" android:theme="@style/UnityThemeSelector">

to

Thanx to @androidbloke,
I have added some library that I know for multiple image picker in swift.
Will update list as I find new ones.
Thank You.

In my case, I tried most of the answers above. I solve this problem by:

• Cleaning all items in the .m2/repository folder
• Uninstall Intellij Ultimate Version
• Install Community Version

It so amazingly worked!

Do ctrl+F5 to compile and run your project without debugging. Look at the output pane (defaults to "Show output from Build"). If it compiled successfully, the path to the .exe file should be there after {projectname}.vcxproj ->

Using Git Bash on Windows 10 and Python36 for Windows I found the virtualenvwrapper.sh in a slightly different place and running this resolved the issue

source virtualenvwrapper.sh 
/c/users/[myUserName]/AppData/Local/Programs/Python36/Scripts

This can't be done with pure HTML.

However if you have access to PHP on the Apache server (you tagged the post "apache") it can be done easilly - se the PHP glob function. If not - you might try Server Side Include - it's an Apache thing, and I don't know much about it.

In Chrome 8 the path is always 'C:\fakepath\' with the correct file name.

tl;dr

OffsetDateTime.parse( "2010-03-01T00:00:00-08:00" )

Details

The answer by BalusC is correct, but now outdated as of Java 8.

java.time

The java.time framework is the successor to both Joda-Time library and the old troublesome date-time classes bundled with the earliest versions of Java (java.util.Date/.Calendar & java.text.SimpleDateFormat).

ISO 8601

Your input data string happens to comply with the ISO 8601 standard.

The java.time classes use ISO 8601 formats by default when parsing/generating textual representations of date-time values. So no need to define a formatting pattern.

OffsetDateTime

The OffsetDateTime class represents a moment on the time line adjusted to some particular offset-from-UTC. In your input, the offset is 8 hours behind UTC, commonly used on much of the west coast of North America.

OffsetDateTime odt = OffsetDateTime.parse( "2010-03-01T00:00:00-08:00" );

You seem to want the date-only, in which case use the LocalDate class. But keep in mind you are discarding data, (a) time-of-day, and (b) the time zone. Really, a date has no meaning without the context of a time zone. For any given moment the date varies around the world. For example, just after midnight in Paris is still “yesterday” in Montréal. So while I suggest sticking with date-time values, you can easily convert to a LocalDate if you insist.

LocalDate localDate = odt.toLocalDate();

Time Zone

If you know the intended time zone, apply it. A time zone is an offset plus the rules to use for handling anomalies such as Daylight Saving Time (DST). Applying a ZoneId gets us a ZonedDateTime object.

ZoneId zoneId = ZoneId.of( "America/Los_Angeles" );
ZonedDateTime zdt = odt.atZoneSameInstant( zoneId );

Generating strings

To generate a string in ISO 8601 format, call toString.

String output = odt.toString();

If you need strings in other formats, search Stack Overflow for use of the java.util.format package.

Converting to java.util.Date

Best to avoid java.util.Date, but if you must, you can convert. Call the new methods added to the old classes such as java.util.Date.from where you pass an Instant. An Instant is a moment on the timeline in UTC. We can extract an Instant from our OffsetDateTime.

java.util.Date utilDate = java.util.Date( odt.toInstant() );

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

From Visual Studio 2015 consider to use out of the box Memory Usage diagnostic tool to collect and analyze memory usage data.

The Memory Usage tool lets you take one or more snapshots of the managed and native memory heap to help understand the memory usage impact of object types.

It depends on what you mean by button. If it is a link:

<%= Html.ActionLink("some text", "actionName", "controllerName") %>

For posting you could use a form:

<% using(Html.BeginForm("actionName", "controllerName")) { %>
    <input type="submit" value="Some text" />
<% } %>

And finally if you have a button:

<input type="button" value="Some text" onclick="window.location.href='<%= Url.Action("actionName", "controllerName") %>';" />

Many of you must be landing here to find a solution for opaque border instead of a transparent one. In that case you can use rgba, where a stands for alpha.

.your_class {
    height: 100px;
    width: 100px;
    margin: 100px;
    border: 10px solid rgba(255,255,255,.5);
}

Demo

Here, you can change the opacity of the border from 0-1

If you simply want a complete transparent border, the best thing to use is transparent, like border: 1px solid transparent;

The following code snippet enables/disables a button depending on whether at least one checkbox on the page has been checked.

$('input[type=checkbox]').change(function () {
    $('#test > tbody  tr').each(function () {
        if ($('input[type=checkbox]').is(':checked')) {
            $('#btnexcellSelect').removeAttr('disabled');
        } else {
            $('#btnexcellSelect').attr('disabled', 'disabled');
        }
        if ($(this).is(':checked')){
            console.log( $(this).attr('id'));
         }else{
             console.log($(this).attr('id'));
         }
     });
});

Here is demo in JSFiddle.

Set<E> and List<E> are both used to store elements of type E. The difference is that Set is stored in unordered way and does not allow duplicate values. List is used to store elements in ordered way and it does allow duplicate values.

Set elements cannot be accessed by an index position, and List elements can be accessed with an index position.

Python has a min() built-in function:

>>> darr = [1, 3.14159, 1e100, -2.71828]
>>> min(darr)
-2.71828

For those looking for answers for SQL Server 2016+. Use the built-in STRING_SPLIT function

Eg:

DECLARE @tags NVARCHAR(400) = 'clothing,road,,touring,bike'  

SELECT value

As it is described at decimal as:

The decimal keyword indicates a 128-bit data type. Compared to floating-point types, the decimal type has more precision and a smaller range, which makes it appropriate for financial and monetary calculations.

You can use a decimal as follows:

decimal myMoney = 300.5m;

Use the Intel x86 Emulator Accelerator

First, install the Intel x86 Emulator Accelerator (HAXM). This can be downloaded directly from Intel or using Android SDK Manager. In the SDK Manager, it's located under Extras.

In the version of Android Studio I used (0.8.9), Android SDK Manager downloads HAXM but doesn't actually run the installer (I assume this will be fixed in later releases). To run the installer I had to go to C:\Program Files (x86)\Android\android-studio\sdk\extras\intel\Hardware_Accelerated_Execution_Manager and manually launch intelhaxm.exe.

HAXM works with Intel devices, so created a new Emulator with Intel CPU.

Create a new AVD using Intel Atom x86

This improved things considerably, but the emulator was still feeling a bit sluggish. The final step was selecting Use Host GPU in Android Virtual Device Manager (AVD).

After these changes, Android Emulator was launching in 5-10 seconds and running without any noticeable lag. Be aware that these features are hardware dependent (CPU/GPU) and may not work on some systems.

TRY THIS Interface used to write a DataFrame to external storage systems (e.g. file systems, key-value stores, etc). Use DataFrame.write() to access this.

New in version 1.4.

csv(path, mode=None, compression=None, sep=None, quote=None, escape=None, header=None, nullValue=None, escapeQuotes=None, quoteAll=None, dateFormat=None, timestampFormat=None) Saves the content of the DataFrame in CSV format at the specified path.

Parameters: path – the path in any Hadoop supported file system mode – specifies the behavior of the save operation when data already exists.

append: Append contents of this DataFrame to existing data. overwrite: Overwrite existing data. ignore: Silently ignore this operation if data already exists. error (default case): Throw an exception if data already exists. compression – compression codec to use when saving to file. This can be one of the known case-insensitive shorten names (none, bzip2, gzip, lz4, snappy and deflate). sep – sets the single character as a separator for each field and value. If None is set, it uses the default value, ,. quote – sets the single character used for escaping quoted values where the separator can be part of the value. If None is set, it uses the default value, ". If you would like to turn off quotations, you need to set an empty string. escape – sets the single character used for escaping quotes inside an already quoted value. If None is set, it uses the default value, \ escapeQuotes – A flag indicating whether values containing quotes should always be enclosed in quotes. If None is set, it uses the default value true, escaping all values containing a quote character. quoteAll – A flag indicating whether all values should always be enclosed in quotes. If None is set, it uses the default value false, only escaping values containing a quote character. header – writes the names of columns as the first line. If None is set, it uses the default value, false. nullValue – sets the string representation of a null value. If None is set, it uses the default value, empty string. dateFormat – sets the string that indicates a date format. Custom date formats follow the formats at java.text.SimpleDateFormat. This applies to date type. If None is set, it uses the default value value, yyyy-MM-dd. timestampFormat – sets the string that indicates a timestamp format. Custom date formats follow the formats at java.text.SimpleDateFormat. This applies to timestamp type. If None is set, it uses the default value value, yyyy-MM-dd'T'HH:mm:ss.SSSZZ.

Try this (faster and simpler):

newData <- data^2

What worked for me in python 3.7 and img2pdf version 0.4.0 was to use something similar to the code given by Syed Shamikh Shabbir but changing the current working directory using OS as Stu suggested in his comment to Syed's solution

import os
import img2pdf

path = './path/to/folder'
os.chdir(path)
images = [i for i in os.listdir(os.getcwd()) if i.endswith(".jpg")]

for image in images:
    with open(image[:-4] + ".pdf", "wb") as f:
        f.write(img2pdf.convert(image))

It is worth mentioning this solution above saves each .jpg separately in one single pdf. If you want all your .jpg files together in only one .pdf you could do:

import os
import img2pdf

path = './path/to/folder'
os.chdir(path)
images = [i for i in os.listdir(os.getcwd()) if i.endswith(".jpg")]

with open("output.pdf", "wb") as f:
    f.write(img2pdf.convert(images))

I used this (need to run it only once); also make sure you have rights to execute:

from PowerShell with elevated rights:

Set-ExecutionPolicy=RemoteSigned

then from a bat file:

-----------------------------------------

 ftype Microsoft.PowerShellScript.1="C:\WINDOWS\system32\windowspowershell\v1.0\powershell.exe" -noexit ^&'%%1'

 assoc .ps1=Microsoft.PowerShellScript.1

-----------------------------------------
auto exit: remove -noexit 

and voila; double-clicking a *.ps1 will execute it.

just insert this jquery code to your HTML's head section:

<!--[if lt IE 9 ]>
     <script>
        $(document).ready(function(){
            $('a > button').click(function(){
                window.location.href = $(this).parent().attr('href');
            });
        });
    </script>
<![endif]-->

To check that the file you're trying to open actually exists, you can change directories in terminal using cd. To change to ~/Desktop/sass/css: cd ~/Desktop/sass/css. To see what files are in the directory: ls.

If you want information about either of those commands, use the man page: man cd or man ls, for example.

Google for "basic unix command line commands" or similar; that will give you numerous examples of moving around, viewing files, etc in the command line.

On Mac OS X, you can also use open to open a finder window: open . will open the current directory in finder. (open ~/Desktop/sass/css will open the ~/Desktop/sass/css).

I'm assuming you want all three of those as part of the selection criteria. You'll need a few statements in your where but they will be similar to the link your question contained.

SELECT *
  FROM MyTable
  WHERE [dateColumn] > '3/1/2009' AND [dateColumn] <= DATEADD(day,1,'3/31/2009') 
        --make it inclusive for a datetime type
    AND DATEPART(hh,[dateColumn]) >= 6 AND DATEPART(hh,[dateColumn]) <= 22 
        -- gets the hour of the day from the datetime
    AND DATEPART(dw,[dateColumn]) >= 3 AND DATEPART(dw,[dateColumn]) <= 5 
        -- gets the day of the week from the datetime

Hope this helps.

"Headers already sent" means that your PHP script already sent the HTTP headers, and as such it can't make modifications to them now.

Check that you don't send ANY content before calling session_start. Better yet, just make session_start the first thing you do in your PHP file (so put it at the absolute beginning, before all HTML etc).

You need not specify receiver. You can use adb instead.

adb shell am broadcast -a com.whereismywifeserver.intent.TEST 
--es sms_body "test from adb"

For more arguments such as integer extras, see the documentation.

(Make sure to install react-router using npm!)

To use react-router, you do the following:

1. Create a file with routes defined using Route, IndexRoute components

2. Inject the Router (with 'r'!) component as the top-level component for your app, passing the routes defined in the routes file and a type of history (hashHistory, browserHistory)

3. Add {this.props.children} to make sure new pages will be rendered there
4. Use the Link component to change pages

Step 1 routes.js

import React from 'react';
import { Route, IndexRoute } from 'react-router';

/**
 * Import all page components here
 */
import App from './components/App';
import MainPage from './components/MainPage';
import SomePage from './components/SomePage';
import SomeOtherPage from './components/SomeOtherPage';

/**
 * All routes go here.
 * Don't forget to import the components above after adding new route.
 */
export default (
  <Route path="/" component={App}>
    <IndexRoute component={MainPage} />
    <Route path="/some/where" component={SomePage} />
    <Route path="/some/otherpage" component={SomeOtherPage} />
  </Route>
);

Step 2 entry point (where you do your DOM injection)

// You can choose your kind of history here (e.g. browserHistory)
import { Router, hashHistory as history } from 'react-router';
// Your routes.js file
import routes from './routes';

ReactDOM.render(
  <Router routes={routes} history={history} />,
  document.getElementById('your-app')
);

Step 3 The App component (props.children)

In the render for your App component, add {this.props.children}:

render() {
  return (
    <div>
      <header>
        This is my website!
      </header>

      <main>
        {this.props.children}
      </main>

      <footer>
        Your copyright message
      </footer>
    </div>
  );
}

Step 4 Use Link for navigation

Anywhere in your component render function's return JSX value, use the Link component:

import { Link } from 'react-router';
(...)
<Link to="/some/where">Click me</Link>

In eclipse Galileo :

• Open the project's properties
• Select Java Build Path
• Select Libraries tab

From there you can Add External Jars

I have used WebLOAD for this kind of project. It's easy to create scripts, and it has built in support for monitoring ASP.NET stats

I don't know that you can do it in Chrome outside of Windows -- some Googling shows that Chrome (and therefore possibly Chromium) might respond well to a certain registry hack.

However, if you're just looking for a simple solution without modifying your code base, have you considered Firefox? In the about:config you can search for "network.http.max" and there are a few values in there that are definitely worth looking at.

Also, for a device that will not be moving (i.e. it is mounted in a fixed location) you should consider not using Wi-Fi (even a Home-Plug would be a step up as far as latency / stability / dropped connections go).

you have to call it like this

SELECT dbo.CheckIfSFExists(23, default)

From Technet:

When a parameter of the function has a default value, the keyword DEFAULT must be specified when the function is called in order to retrieve the default value. This behaviour is different from using parameters with default values in stored procedures in which omitting the parameter also implies the default value. An exception to this behaviour is when invoking a scalar function by using the EXECUTE statement. When using EXECUTE, the DEFAULT keyword is not required.

use of this code you want to download file store automatically in Document Directory in your application

this code 100% Working

A solution very simple, but you have to know the index of the original position and the index of the new position:

list1[index1],list1[index2]=list1[index2],list1[index1]

It's identical to commenting out the block, except with one important difference: Nesting is not a problem. Consider this code:

foo();
bar(x, y); /* x must not be NULL */
baz();

If I want to comment it out, I might try:

/*
foo();
bar(x, y); /* x must not be NULL */
baz();
*/

Bzzt. Syntax error! Why? Because block comments do not nest, and so (as you can see from SO's syntax highlighting) the */ after the word "NULL" terminates the comment, making the baz call not commented out, and the */ after baz a syntax error. On the other hand:

#if 0
foo();
bar(x, y); /* x must not be NULL */
baz();
#endif

Works to comment out the entire thing. And the #if 0s will nest with each other, like so:

#if 0
pre_foo();
#if 0
foo();
bar(x, y); /* x must not be NULL */
baz();
#endif
quux();
#endif

Although of course this can get a bit confusing and become a maintenance headache if not commented properly.

If it is one (single) branch that you need to check, for example if you want that branch 'B' is fully merged into branch 'A', you can simply do the following:

$ git checkout A
$ git branch -d B

git branch -d <branchname> has the safety that "The branch must be fully merged in HEAD."

Caution: this actually deletes the branch B if it is merged into A.

It's simple, whenever Docker build is run, docker wants to know, what's the image name, so we need to pass -t : . Now make sure you are in the same directory where you have your Dockerfile and run

docker build -t <image_name>:<version> . Example docker build -t my_apache:latest . assuming you are in the same directory as your Dockerfile otherwise pass -f flag and the Dockerfile.

docker build -t my_apache:latest -f ~/Users/documents/myapache/Dockerfile

When you set the Drawable of an ImageView by using the setBackgroundDrawable method, the image will always be scaled. Parameters as adjustViewBounds or different ScaleTypes will just be ignored. The only solution to keep the aspect ratio I found, is to resize the ImageView after loading your drawable. Here is the code snippet I used:

// bmp is your Bitmap object
int imgHeight = bmp.getHeight();
int imgWidth = bmp.getWidth();
int containerHeight = imageView.getHeight();
int containerWidth = imageView.getWidth();
boolean ch2cw = containerHeight > containerWidth;
float h2w = (float) imgHeight / (float) imgWidth;
float newContainerHeight, newContainerWidth;

if (h2w > 1) {
    // height is greater than width
    if (ch2cw) {
        newContainerWidth = (float) containerWidth;
        newContainerHeight = newContainerWidth * h2w;
    } else {
        newContainerHeight = (float) containerHeight;
        newContainerWidth = newContainerHeight / h2w;
    }
} else {
    // width is greater than height
    if (ch2cw) {
        newContainerWidth = (float) containerWidth;
        newContainerHeight = newContainerWidth / h2w; 
    } else {
        newContainerWidth = (float) containerHeight;
        newContainerHeight = newContainerWidth * h2w;       
    }
}
Bitmap copy = Bitmap.createScaledBitmap(bmp, (int) newContainerWidth, (int) newContainerHeight, false);
imageView.setBackgroundDrawable(new BitmapDrawable(copy));
LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
imageView.setLayoutParams(params);
imageView.setMaxHeight((int) newContainerHeight);
imageView.setMaxWidth((int) newContainerWidth);

In the code snippet above is bmp the Bitmap object that is to be shown and imageView is the ImageView object

An important thing to note is the change of the layout parameters. This is necessary because setMaxHeight and setMaxWidth will only make a difference if the width and height are defined to wrap the content, not to fill the parent. Fill parent on the other hand is the desired setting at the beginning, because otherwise containerWidth and containerHeight will both have values equal to 0. So, in your layout file you will have something like this for your ImageView:

...
<ImageView android:id="@+id/my_image_view"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"/>
...

Eclipse does not have internal Subversion connectivity. After you've downloaded and unzipped Eclipse, you have to install a Subversion plug-in. Check with the other developers as to which Subversion plug-in you're using. Subclipse is one Subversion plug-in.

After you've installed the Subversion plug-in, you have to give Eclipse the repository information in the SVN Repositories view of the SVN Repositories perspective. One of the other developers should have that information.

Finally, you check out the project from Subversion, by left clicking on the Package Explorer, selecting New -> Project, and in the New Project wizard,left clicking on SVN -> Checkout projects from SVN.

A visual tree with branch names included.

Use this to add it as an alias

git config --global alias.tree "log --oneline --decorate --all --graph"

You call it with

There are excellent answers, but if you want to color your console logs you can use the pattern :

<PatternLayout pattern="%style{%date{DEFAULT}}{yellow}
            [%t] %highlight{%-5level}{FATAL=bg_red, ERROR=red, WARN=yellow, INFO=green} %logger{36} - %message\n"/>

The full log4j2 file is:

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
    <Properties>
        <Property name="APP_LOG_ROOT">/opt/test/log</Property>
    </Properties>
    <Appenders>
        <Console name="ConsoleAppender" target="SYSTEM_OUT">
            <PatternLayout pattern="%style{%date{DEFAULT}}{yellow}
                [%t] %highlight{%-5level}{FATAL=bg_red, ERROR=red, WARN=yellow, INFO=green} %logger{36} - %message\n"/>
        </Console>
        <RollingFile name="XML_ROLLING_FILE_APPENDER"
                     fileName="${APP_LOG_ROOT}/appName.log"
                     filePattern="${APP_LOG_ROOT}/appName-%d{yyyy-MM-dd}-%i.log.gz">
            <PatternLayout pattern="%d{DEFAULT} [%t] %-5level %logger{36} - %msg%n"/>
            <Policies>
                <SizeBasedTriggeringPolicy size="19500KB"/>
            </Policies>
        </RollingFile>
    </Appenders>
    <Loggers>
        <Root level="error">
            <AppenderRef ref="ConsoleAppender"/>
        </Root>
        <Logger name="com.compName.projectName" level="debug">
            <AppenderRef ref="XML_ROLLING_FILE_APPENDER"/>
        </Logger>
    </Loggers>
</Configuration>

And the logs will look like this:

add padding:inherit in your absolute position

.box{_x000D_
  background: red;_x000D_
  position: relative;_x000D_
  padding: 30px;_x000D_
  width:500px;_x000D_
  height:200px;_x000D_
 box-sizing: border-box;_x000D_
 _x000D_
_x000D_
}

<div  class="box">_x000D_
_x000D_
  <div style="position: absolute;left:0;top:0;padding: inherit">top left</div>_x000D_
  <div style="position: absolute;right:0;top:0;padding: inherit">top right</div>_x000D_
  <div style="text-align: center;padding: inherit">center</div>_x000D_
  <div style="position: absolute;left:0;bottom:0;padding: inherit">bottom left</div>_x000D_
  <div style="position: absolute;right:0;bottom:0;padding: inherit">bottom right</div>_x000D_
_x000D_
_x000D_
</div>

You don't need jquery in order to do that.

var placeHolder="name";
var res=name.substr(name.indexOf(placeHolder) + placeHolder.length);

Your code is failing on this line:

var RUnits = Math.abs(document.all.Capacity.RUnits.value);

i tried stepping though it with firebug and it fails there. that should help you figure out the problem.

you have jquery referenced. you might as well use it in all these functions. it'll clean up your code significantly.

Also if a function returns an array, but the function is called without assigning its returned data to any variable like below. Here split() is called, but it is not assigned to any variable. We can access its returned data later through @_:

$str = "Mr.Bond|Chewbaaka|Spider-Man";
split(/\|/, $str);

print @_[0]; # 'Mr.Bond'

This will split the string $str and set the array @_.

Adding another option, if jq is available:

export NAMES="{
  \"Mary\":\"100\",
  \"John\":\"200\",
  \"Mary\":\"50\",
  \"John\":\"300\",
  \"Paul\":\"100\",
  \"Paul\":\"400\",
  \"David\":\"100\"
}"
export NAME=David
echo $NAMES | jq --arg v "$NAME" '.[$v]' | tr -d '"' 

$date = DateTime::createFromFormat('m-d-Y', '04-15-2013');
$date->modify('+1 day');
echo $date->format('m-d-Y');

See it in action

Or in PHP 5.4+

echo (DateTime::createFromFormat('m-d-Y', '04-15-2013'))->modify('+1 day')->format('m-d-Y');

reference

• DateTime::createFromFormat()

(See here also for my C++11 answer)

In order to parse a C++ program, the compiler needs to know whether certain names are types or not. The following example demonstrates that:

t * f;

How should this be parsed? For many languages a compiler doesn't need to know the meaning of a name in order to parse and basically know what action a line of code does. In C++, the above however can yield vastly different interpretations depending on what t means. If it's a type, then it will be a declaration of a pointer f. However if it's not a type, it will be a multiplication. So the C++ Standard says at paragraph (3/7):

Some names denote types or templates. In general, whenever a name is encountered it is necessary to determine whether that name denotes one of these entities before continuing to parse the program that contains it. The process that determines this is called name lookup.

How will the compiler find out what a name t::x refers to, if t refers to a template type parameter? x could be a static int data member that could be multiplied or could equally well be a nested class or typedef that could yield to a declaration. If a name has this property - that it can't be looked up until the actual template arguments are known - then it's called a dependent name (it "depends" on the template parameters).

You might recommend to just wait till the user instantiates the template:

Let's wait until the user instantiates the template, and then later find out the real meaning of t::x * f;.

This will work and actually is allowed by the Standard as a possible implementation approach. These compilers basically copy the template's text into an internal buffer, and only when an instantiation is needed, they parse the template and possibly detect errors in the definition. But instead of bothering the template's users (poor colleagues!) with errors made by a template's author, other implementations choose to check templates early on and give errors in the definition as soon as possible, before an instantiation even takes place.

So there has to be a way to tell the compiler that certain names are types and that certain names aren't.

The "typename" keyword

The answer is: We decide how the compiler should parse this. If t::x is a dependent name, then we need to prefix it by typename to tell the compiler to parse it in a certain way. The Standard says at (14.6/2):

A name used in a template declaration or definition and that is dependent on a template-parameter is assumed not to name a type unless the applicable name lookup finds a type name or the name is qualified by the keyword typename.

There are many names for which typename is not necessary, because the compiler can, with the applicable name lookup in the template definition, figure out how to parse a construct itself - for example with T *f;, when T is a type template parameter. But for t::x * f; to be a declaration, it must be written as typename t::x *f;. If you omit the keyword and the name is taken to be a non-type, but when instantiation finds it denotes a type, the usual error messages are emitted by the compiler. Sometimes, the error consequently is given at definition time:

// t::x is taken as non-type, but as an expression the following misses an
// operator between the two names or a semicolon separating them.
t::x f;

The syntax allows typename only before qualified names - it is therefor taken as granted that unqualified names are always known to refer to types if they do so.

A similar gotcha exists for names that denote templates, as hinted at by the introductory text.

The "template" keyword

Remember the initial quote above and how the Standard requires special handling for templates as well? Let's take the following innocent-looking example:

boost::function< int() > f;

It might look obvious to a human reader. Not so for the compiler. Imagine the following arbitrary definition of boost::function and f:

namespace boost { int function = 0; }
int main() { 
  int f = 0;
  boost::function< int() > f; 
}

That's actually a valid expression! It uses the less-than operator to compare boost::function against zero (int()), and then uses the greater-than operator to compare the resulting bool against f. However as you might well know, boost::function in real life is a template, so the compiler knows (14.2/3):

After name lookup (3.4) finds that a name is a template-name, if this name is followed by a <, the < is always taken as the beginning of a template-argument-list and never as a name followed by the less-than operator.

Now we are back to the same problem as with typename. What if we can't know yet whether the name is a template when parsing the code? We will need to insert template immediately before the template name, as specified by 14.2/4. This looks like:

t::template f<int>(); // call a function template

Template names can not only occur after a :: but also after a -> or . in a class member access. You need to insert the keyword there too:

this->template f<int>(); // call a function template

Dependencies

For the people that have thick Standardese books on their shelf and that want to know what exactly I was talking about, I'll talk a bit about how this is specified in the Standard.

In template declarations some constructs have different meanings depending on what template arguments you use to instantiate the template: Expressions may have different types or values, variables may have different types or function calls might end up calling different functions. Such constructs are generally said to depend on template parameters.

The Standard defines precisely the rules by whether a construct is dependent or not. It separates them into logically different groups: One catches types, another catches expressions. Expressions may depend by their value and/or their type. So we have, with typical examples appended:

• Dependent types (e.g: a type template parameter T)
• Value-dependent expressions (e.g: a non-type template parameter N)
• Type-dependent expressions (e.g: a cast to a type template parameter (T)0)

Most of the rules are intuitive and are built up recursively: For example, a type constructed as T[N] is a dependent type if N is a value-dependent expression or T is a dependent type. The details of this can be read in section (14.6.2/1) for dependent types, (14.6.2.2) for type-dependent expressions and (14.6.2.3) for value-dependent expressions.

Dependent names

The Standard is a bit unclear about what exactly is a dependent name. On a simple read (you know, the principle of least surprise), all it defines as a dependent name is the special case for function names below. But since clearly T::x also needs to be looked up in the instantiation context, it also needs to be a dependent name (fortunately, as of mid C++14 the committee has started to look into how to fix this confusing definition).

To avoid this problem, I have resorted to a simple interpretation of the Standard text. Of all the constructs that denote dependent types or expressions, a subset of them represent names. Those names are therefore "dependent names". A name can take different forms - the Standard says:

A name is a use of an identifier (2.11), operator-function-id (13.5), conversion-function-id (12.3.2), or template-id (14.2) that denotes an entity or label (6.6.4, 6.1)

An identifier is just a plain sequence of characters / digits, while the next two are the operator + and operator type form. The last form is template-name <argument list>. All these are names, and by conventional use in the Standard, a name can also include qualifiers that say what namespace or class a name should be looked up in.

A value dependent expression 1 + N is not a name, but N is. The subset of all dependent constructs that are names is called dependent name. Function names, however, may have different meaning in different instantiations of a template, but unfortunately are not caught by this general rule.

Dependent function names

Not primarily a concern of this article, but still worth mentioning: Function names are an exception that are handled separately. An identifier function name is dependent not by itself, but by the type dependent argument expressions used in a call. In the example f((T)0), f is a dependent name. In the Standard, this is specified at (14.6.2/1).

Additional notes and examples

In enough cases we need both of typename and template. Your code should look like the following

template <typename T, typename Tail>
struct UnionNode : public Tail {
    // ...
    template<typename U> struct inUnion {
        typedef typename Tail::template inUnion<U> dummy;
    };
    // ...
};

The keyword template doesn't always have to appear in the last part of a name. It can appear in the middle before a class name that's used as a scope, like in the following example

typename t::template iterator<int>::value_type v;

In some cases, the keywords are forbidden, as detailed below

• On the name of a dependent base class you are not allowed to write typename. It's assumed that the name given is a class type name. This is true for both names in the base-class list and the constructor initializer list:

   template <typename T>
   struct derive_from_Has_type : /* typename */ SomeBase<T>::type 
   { };
  

• In using-declarations it's not possible to use template after the last ::, and the C++ committee said not to work on a solution.

   template <typename T>
   struct derive_from_Has_type : SomeBase<T> {
      using SomeBase<T>::template type; // error
      using typename SomeBase<T>::type; // typename *is* allowed
   };
  

Your code can get messy fast when dealing with CSS3 transitions. I would recommend using a plugin such as jQuery Transit that handles the complexity of CSS3 animations/transitions.

Moreover, the plugin uses webkit-transform rather than webkit-transition, which allows for mobile devices to use hardware acceleration in order to give your web apps that native look and feel when the animations occur.

JS Fiddle Live Demo

Javascript:

$("#startTransition").on("click", function()
{

    if( $(".boxOne").is(":visible")) 
    {
        $(".boxOne").transition({ x: '-100%', opacity: 0.1 }, function () { $(".boxOne").hide(); });
        $(".boxTwo").css({ x: '100%' });
        $(".boxTwo").show().transition({ x: '0%', opacity: 1.0 });
        return;        
    }

    $(".boxTwo").transition({ x: '-100%', opacity: 0.1 }, function () { $(".boxTwo").hide(); });
    $(".boxOne").css({ x: '100%' });
    $(".boxOne").show().transition({ x: '0%', opacity: 1.0 });

});

Most of the hard work of getting cross-browser compatibility is done for you as well and it works like a charm on mobile devices.

You can do that just combining the script name ($0) with realpath and/or dirname. It works for Bash and Shell.

#!/usr/bin/env bash

RELATIVE_PATH="${0}"
RELATIVE_DIR_PATH="$(dirname "${0}")"
FULL_DIR_PATH="$(realpath "${0}" | xargs dirname)"
FULL_PATH="$(realpath "${0}")"

echo "RELATIVE_PATH->${RELATIVE_PATH}<-"
echo "RELATIVE_DIR_PATH->${RELATIVE_DIR_PATH}<-"
echo "FULL_DIR_PATH->${FULL_DIR_PATH}<-"
echo "FULL_PATH->${FULL_PATH}<-"

The output will be something like this:

# RELATIVE_PATH->./bin/startup.sh<-
# RELATIVE_DIR_PATH->./bin<-
# FULL_DIR_PATH->/opt/my_app/bin<-
# FULL_PATH->/opt/my_app/bin/startup.sh<-

$0 is the name of the script itself

4.4. Special Variable Types

An example: LozanoMatheus/get_script_paths.sh

A slightly different approach is to create your formula from a string. In the formula help page you will find the following example :

## Create a formula for a model with a large number of variables:
xnam <- paste("x", 1:25, sep="")
fmla <- as.formula(paste("y ~ ", paste(xnam, collapse= "+")))

Then if you look at the generated formula, you will get :

R> fmla
y ~ x1 + x2 + x3 + x4 + x5 + x6 + x7 + x8 + x9 + x10 + x11 + 
    x12 + x13 + x14 + x15 + x16 + x17 + x18 + x19 + x20 + x21 + 
    x22 + x23 + x24 + x25

This is working

<form name="myform" ng-submit="create()">
    <input type="number"
           name="price_field"
           ng-model="price"
           require
           ng-pattern="/^\d{0,9}(\.\d{1,9})?$/">
    <span  ng-show="myform.price_field.$error.pattern">Not valid number!</span>
    <input type="submit" class="btn">
 </form>

On Arch, i fix like this:

sudo ln -s /usr/lib/libncursesw.so.6 /usr/lib/libtinfo.so.6

If you are like me and need to change color of text itself also while in the same time filling the background color check my solution.

Steps to create:

1. Have two text, one is static colored in color on hover, and the other one in default state color which you will be moving on hover
2. On hover move wrapper of the not static one text while in the same time move inner text of that wrapper to the opposite direction.
3. Make sure to add overflow hidden where needed

Good thing about this solution:

• Support IE9, uses only transform
• Button (or element you are applying animation) is fluid in width, so no fixed values are being used here

Not so good thing about this solution:

• A really messy markup, could be solved by using pseudo elements and att(data)?
• There is some small glitch in animation when having more then one button next to each other, maybe it could be easily solved but I didn't take much time to investigate yet.

Check the pen ---> https://codepen.io/nikolamitic/pen/vpNoNq

<button class="btn btn--animation-from-right">
  <span class="btn__text-static">Cover left</span>
  <div class="btn__text-dynamic">
    <span class="btn__text-dynamic-inner">Cover left</span>
  </div>
</button>

.btn {
  padding: 10px 20px;
  position: relative;

  border: 2px solid #222;
  color: #fff;
  background-color: #222;
  position: relative;

  overflow: hidden;
  cursor: pointer;

  text-transform: uppercase;
  font-family: monospace;
  letter-spacing: -1px;

  [class^="btn__text"] {
    font-size: 24px;
  }

  .btn__text-dynamic,
  .btn__text-dynamic-inner {    
    display: flex;
    justify-content: center;
    align-items: center;

    position: absolute;
    top:0;
    left:0;
    right:0;
    bottom:0;
    z-index: 2;

    transition: all ease 0.5s;
  }

  .btn__text-dynamic {
    background-color: #fff;
    color: #222;

    overflow: hidden;
  }

  &:hover {
    .btn__text-dynamic {
      transform: translateX(-100%);
    }
    .btn__text-dynamic-inner {
      transform: translateX(100%);
    }
  }
}

.btn--animation-from-right {
    &:hover {
    .btn__text-dynamic {
      transform: translateX(100%);
    }
    .btn__text-dynamic-inner {
      transform: translateX(-100%);
    }
  }
}

You can remove .btn--animation-from-right modifier if you want to animate to the left.

If you have to ask an user to give input and then you have to count how many numbers are there then you can follow this:

count_number = input('Please enter a number\t')

print(len(count_number))

Note: Never take an int as user input.

If we see logically programming language and scripting language so this is 99.09% same . because we use same concept like loop , control condition ,variable and all so we can say yes both are same but there is only one thing is different between them that is in C/C++ and other programming language we compile the code before execution . but in the PHP , JavaScript and other scripting language we don't need to compile we directly execute in the browser.

I created this Function after researching on the internet since I wanted to print an XML string when you select a row from a data grid view.

static void HighlightPhrase(RichTextBox box, string StartTag, string EndTag, string ControlTag, Color color1, Color color2)
{
    int pos = box.SelectionStart;
    string s = box.Text;
    for (int ix = 0; ; )
    {
        int jx = s.IndexOf(StartTag, ix, StringComparison.CurrentCultureIgnoreCase);
        if (jx < 0) break;
        int ex = s.IndexOf(EndTag, ix, StringComparison.CurrentCultureIgnoreCase);
        box.SelectionStart = jx;
        box.SelectionLength = ex - jx + 1;
        box.SelectionColor = color1;
        
        int bx = s.IndexOf(ControlTag, ix, StringComparison.CurrentCultureIgnoreCase);
        int bxtest = s.IndexOf(StartTag, (ex + 1), StringComparison.CurrentCultureIgnoreCase);
        if (bx == bxtest)
        {
            box.SelectionStart = ex + 1;
            box.SelectionLength = bx - ex + 1;
            box.SelectionColor = color2;
        }
        
        ix = ex + 1;
    }
    box.SelectionStart = pos;
    box.SelectionLength = 0;
}

and this is how you call it

   HighlightPhrase(richTextBox1, "<", ">","</", Color.Red, Color.Black);
