If you're brave and willing to roll your own, you could start with a PostScript library and augment it to deal with PDF, taking advantage of Adobe's free online PDF reference.

The following open source tools are available:

• ILSpy from the SharpDevelop team. Thanks to Scott Hanselman's tweet highlighting the tool.
• Dotnet IL Editor (a disassembler)
• IL.View - a .NET Reflector alternative written in Silverlight 4 as an Out-of-Browser Silverlight Application. See this blog post for details.

There is an open source HTML5/javascript reader available called Trapeze though its still in its early stages.

Demo site: https://brendandahl.github.io/trapeze-reader/demos/

You can use jasper report.

iReport is a very effective tool to develop jasper reports.

It supports almost all the facilities provided by crystal report like formatting, grouping, creation of charts etc.

Refer the link for tutorial:

TiCPP is a "more c++" version of TinyXML.

'TiCPP' is short for the official name TinyXML++. It is a completely new interface to TinyXML (http://www.grinninglizard.com/tinyxml/) that uses MANY of the C++ strengths. Templates, exceptions, and much better error handling. It is also fully documented in doxygen. It is really cool because this version let's you interface tiny the exact same way as before or you can choose to use the new 'ticpp' classes. All you need to do is define TIXML_USE_TICPP. It has been tested in VC 6.0, VC 7.0, VC 7.1, VC 8.0, MinGW gcc 3.4.5, and in Linux GNU gcc 3+

You all probably already know that an interesting usage for extension methods is as a kind of mixin. Some extension methods, like the XmlSerializable, pollute almost every class; and it doesn't make sense to most of them, like Thread and SqlConnection.

Some functionality should be explicitly mixed in to the classes that want to have it. I propose a new notation to this kind of type, with the M prefix.

The XmlSerializable then, is this:

public interface MXmlSerializable { }
public static class XmlSerializable {
  public static string ToXml(this MXmlSerializable self) {
    if (self == null) throw new ArgumentNullException();
    var serializer = new XmlSerializer(self.GetType());
    using (var writer = new StringWriter()) {
      serializer.Serialize(writer, self);
      return writer.GetStringBuilder().ToString();
    }
  }
  public static T FromXml<T>(string xml) where T : MXmlSerializable {
    var serializer = new XmlSerializer(typeof(T));
    return (T)serializer.Deserialize(new StringReader(xml));
  }
}

A class then mixes it in:

public class Customer : MXmlSerializable {
  public string Name { get; set; }
  public bool Preferred { get; set; }
}

And the usage is simply:

var customer = new Customer { 
  Name = "Guybrush Threepwood", 
  Preferred = true };
var xml = customer.ToXml();

If you like the idea, you can create a new namespace for useful mixins in the project. What do you think?

Oh, and by the way, I think most extension methods should explicitly test for null.

The DB Designer Fork project claims that it can generate FireBird sql scripts.

I heard of RTM (The RT FAQ Manager). Never used it, however.

"Best" helpdesk system is very subjective, of course, but I recommend Request Tracker (aka RT).

It has a default workflow built in, but is easily configured for alternate workflows using the "Scrips" and templates. Very extensible if you want.

In addition to other answers, I recommend you to look at this list:

14 Great Android apps that are also open source

For me, NewsBlur, Hacker News Reader and Astrid were the most helpful. Still, I don't know whether they are "suitable for basic learning".

Fundamentally if you use it as part of a business then its commercial use - so its not a matter of whether the tools are directly generating income or not rather one of if they are being used in support of income generation directly or indirectly.

To take your specific example, if the purpose of the site is to sell or promote your paid services/product then its a commercial enterprise.

Check if mysqli module is installed for your PHP version

$ ls /etc/php/7.0/mods-available/mysql*
/etc/php/7.0/mods-available/mysqli.ini /etc/php/7.0/mods-available/mysqlnd.ini

Enable the module

$ sudo phpenmod mysqli

Some of these built in functions should work:

I'm posting this because (to my surprise) there was no other place I could find that recommended this.

There's a really easy way to do this, without restricting you to browser-defined input dimensions. Just use the <label> tag around a hidden file upload button. This allows for even more freedom in styling than the styling allowed via webkit's built-in styling^[1].

The label tag was made for the exact purpose of directing any click events on it to the child inputs^[2], so using that, you won't require any JavaScript to direct the click event to the input button for you anymore. You'd to use something like the following:

label.myLabel input[type="file"] {_x000D_
    position:absolute;_x000D_
    top: -1000px;_x000D_
}_x000D_
_x000D_
/***** Example custom styling *****/_x000D_
.myLabel {_x000D_
    border: 2px solid #AAA;_x000D_
    border-radius: 4px;_x000D_
    padding: 2px 5px;_x000D_
    margin: 2px;_x000D_
    background: #DDD;_x000D_
    display: inline-block;_x000D_
}_x000D_
.myLabel:hover {_x000D_
    background: #CCC;_x000D_
}_x000D_
.myLabel:active {_x000D_
    background: #CCF;_x000D_
}_x000D_
.myLabel :invalid + span {_x000D_
    color: #A44;_x000D_
}_x000D_
.myLabel :valid + span {_x000D_
    color: #4A4;_x000D_
}

<label class="myLabel">_x000D_
    <input type="file" required/>_x000D_
    <span>My Label</span>_x000D_
</label>

I've used a fixed position to hide the input, to make it work even in ancient versions of Internet Explorer (emulated IE8- refused to work on a visibility:hidden or display:none file-input). I've tested in emulated IE7 and up, and it worked perfectly.

1. You can't use <button>s inside <label> tags unfortunately, so you'll have to define the styles for the buttons yourself. To me, this is the only downside to this approach.
2. If the for attribute is defined, its value is used to trigger the input with the same id as the for attribute on the <label>.

I would use virtualenv at your HOME directory.

$ sudo easy_install -U virtualenv
$ cd ~
$ virtualenv .
$ bin/pip ...

You could then also alter ~/.(login|profile|bash_profile), whichever is right for your shell to add ~/bin to your PATH and then that pip|python|easy_install would be the one used by default.

The Popup class might be better than the Stage class, depending on what you want. Stage is either modal (you can't click on anything else in your app) or it vanishes if you click elsewhere in your app (because it's a separate window). Popup stays on top but is not modal.

See this Popup Window example.

This doesn't directly answer your question, but it does solve your problem...

What make of router do you have? Your router firmware may allow you to set DNS records for your local network. This is what I do with the Tomato firmware

It's also possible letting a ServletContextListener set the System properties:

import java.util.Enumeration;
import javax.servlet.*;

public class SystemPropertiesHelper implements
        javax.servlet.ServletContextListener {
    private ServletContext context = null;

    public void contextInitialized(ServletContextEvent event) {
        context = event.getServletContext();
        Enumeration<String> params = context.getInitParameterNames();

        while (params.hasMoreElements()) {
          String param = (String) params.nextElement();
          String value = 
            context.getInitParameter(param);
          if (param.startsWith("customPrefix.")) {
              System.setProperty(param, value);
          }
        }
    }

    public void contextDestroyed(ServletContextEvent event) {
    }
}

And then put this into your web.xml (should be possible for context.xml too)

<context-param>
        <param-name>customPrefix.property</param-name>
        <param-value>value</param-value>
        <param-type>java.lang.String</param-type>
</context-param>

<listener>
    <listener-class>servletUtils.SystemPropertiesHelper</listener-class>    
</listener>

It worked for me.

I just click on latest swift convert button and set App target build setting-> Swift language version: swift 4.0,

Hope this will help.

readlink -e [filepath]

seems to be exactly what you're asking for - it accepts an arbirary path, resolves all symlinks, and returns the "real" path - and it's "standard *nix" that likely all systems already have

Try like this as well

covertPostSub("/xyz/test.jsp","?param1=param1&param2=param2","_self","true");

    var Popup = null;
    var form = document.createElement("form");
    form.setAttribute("method", "POST");
    form.setAttribute("id","TheForm");
    form.setAttribute("action", action);
    form.setAttribute("target", targetIframe);
    var params = paramsTosend;
    params = params.substring(1, params.length);
    params = params.split("&");
    for(var key=0; key<params.length; key++) {
        var sa = params[key];
        sa = sa.split("=");
        var xs = (sa[1]);

        if(params.hasOwnProperty(key)) {
            var hiddenField = document.createElement("input");
            hiddenField.setAttribute("type", "hidden");
            hiddenField.setAttribute("name", sa[0]);
            hiddenField.setAttribute("value",xs);

            form.appendChild(hiddenField);
         }
    }
    document.body.appendChild(form);
    form.style.display = "none";
    if(isWindow){
        window.open('', "formpopup","width=900,height=590,toolbar=no,scrollbars=yes,resizable=no,location=0,directories=0,status=1,menubar=0,left=60,top=60");
        form.target = 'formpopup';
        form.submit();
    }else{
        form.submit();
    }

}

In my case the problem was in a child jar which was not rebuilt since I have added a new class, pom.xml of that child jar was not related to my failed pom.xml as child-to-parent relation (using <parent> tag). So I rebuilt the child jar after which the error had gone.

You can use Java 8 streams, for example

set1.stream().filter(s -> set2.contains(s)).collect(Collectors.toSet());

or Sets class from Guava:

Set<String> intersection = Sets.intersection(set1, set2);
Set<String> difference = Sets.difference(set1, set2);
Set<String> symmetricDifference = Sets.symmetricDifference(set1, set2);
Set<String> union = Sets.union(set1, set2);

You can get the maximum key this way:

<?php
$arr = array("a"=>"test", "b"=>"ztest");
$max = max(array_keys($arr));
?>

Click the "Remove all Sessions" button in the toolbar of the "Coverage" view.

There are several detail levels you can get when looking at OpenPGP key data: a basic summary, a machine-readable output of this summary or a detailed (and very technical) list of the individual OpenPGP packets.

Basic Key Information

For a brief peak at an OpenPGP key file, you can simply pass the filename as parameter or pipe in the key data through STDIN. If no command is passed, GnuPG tries to guess what you want to do -- and for key data, this is printing a summary on the key:

Providing -v or -vv will even add some more information. I prefer printing the package details in this case, though (see below).

Machine-Readable Output

GnuPG also has a colon-separated output format, which is easily parsable and has a stable format. The format is documented in GnuPG doc/DETAILS file. The option to receive this format is --with-colons.

Since GnuPG 2.1.23, the gpg: WARNING: no command supplied. Trying to guess what you mean ... warning can be omitted by using the --import-options show-only option together with the --import command (this also works without --with-colons, of course):

$ gpg --with-colons --import-options show-only --import a4ff2279

For older versions: the warning message is printed on STDERR, so you could just read STDIN to split apart the key information from the warning.

Technical Details: Listing OpenPGP Packets

Without installing any further packages, you can use gpg --list-packets [file] to view information on the OpenPGP packets contained in the file.

$ gpg --list-packets a4ff2279.asc

The pgpdump [file] tool works similar to gpg --list-packets and provides a similar output, but resolves all those algorithm identifiers to readable representations. It is available for probably all relevant distributions (on Debian derivatives, the package is called pgpdump like the tool itself).

You can also pipe in the file names which might be useful:

find /path/to/files -name \*.txt | tar -cvf allfiles.tar -T -

To follow unobtrusive JavaScript programming conventions, and depending on how quickly the DOM will load, it may be a good idea to use the following:

<form onsubmit="return false;"></form>

Then wire up events using the onload or DOM ready if you're using a library.

$(function() {_x000D_
    var $form = $('#my-form');_x000D_
    $form.removeAttr('onsubmit');_x000D_
    $form.submit(function(ev) {_x000D_
        // quick validation example..._x000D_
        $form.children('input[type="text"]').each(function(){_x000D_
            if($(this).val().length == 0) {_x000D_
                alert('You are missing a field');_x000D_
                ev.preventDefault();_x000D_
            }_x000D_
        });_x000D_
    });_x000D_
});

label {_x000D_
    display: block;_x000D_
}_x000D_
_x000D_
#my-form > input[type="text"] {_x000D_
    background: cyan;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<form id="my-form" action="http://google.com" method="GET" onsubmit="return false;">_x000D_
    <label>Your first name</label>_x000D_
    <input type="text" name="first-name"/>_x000D_
    <label>Your last name</label>_x000D_
    <input type="text" name="last-name" /> <br />_x000D_
    <input type="submit" />_x000D_
</form>

Also, I would always use the action attribute as some people may have some plugin like NoScript running which would then break the validation. If you're using the action attribute, at the very least your user will get redirected by the server based on the backend validation. If you're using something like window.location, on the other hand, things will be bad.

For Windows, here's a link to an example batch file that only allows changes to the log message (not other properties):

http://ayria.livejournal.com/33438.html

Basically copy the code below into a text file and name it pre-revprop-change.bat and save it in the \hooks subdirectory for your repository.

@ECHO OFF
:: Set all parameters. Even though most are not used, in case you want to add
:: changes that allow, for example, editing of the author or addition of log messages.
set repository=%1
set revision=%2

set action=%5

:: Only allow the log message to be changed, but not author, etc.
if /I not "%propertyName%" == "svn:log" goto ERROR_PROPNAME

:: Only allow modification of a log message, not addition or deletion.
if /I not "%action%" == "M" goto ERROR_ACTION

:: Make sure that the new svn:log message is not empty.
set bIsEmpty=true
for /f "tokens=*" %%g in ('find /V ""') do (
set bIsEmpty=false
)
if "%bIsEmpty%" == "true" goto ERROR_EMPTY

goto :eof

:ERROR_EMPTY
echo Empty svn:log messages are not allowed. >&2
goto ERROR_EXIT

:ERROR_PROPNAME
echo Only changes to svn:log messages are allowed. >&2
goto ERROR_EXIT

:ERROR_ACTION
echo Only modifications to svn:log revision properties are allowed. >&2
goto ERROR_EXIT

:ERROR_EXIT
exit /b 1

You can use the extension method of Request:

Request.GetDisplayUrl()

Just reciprocating Alex's answer but with jQuery:

var e = $('#myFrame');
    e.attr("src", e.attr("src"));

Or you can use small function:

I hope it helps.

If its windows 2003 / IIS 6.0 then check out AspMaxRequestEntityAllowed = "204800" in the file metabase.xml located in folder C:\windows\system32\inetsrv\

The default value of "204800" (~205Kb) is in my opinion too low for most users. Just change the value to what you think should be max.

If you cant save the file after editing it you have to either stop the ISS-server or enable the server to allow editing of the file:

_{(source: itmaskinen.se)}

Edit: I did not read the question correct (how to set the maxrequest in webconfig). But this informatin may be of interrest for other people, many people who move their sites from win2000-server to win2003 and had a working upload-function and suddenly got the Request.BinaryRead Failed error will have use of it. So I leave the answer here.

When i tried the difference between same time stamp it gave 0 Days 5 Hours 30 Minutes

so to get it exactly i have subtracted 5 hours and 30 min

function get_time_diff( datetime )
{
var datetime = typeof datetime !== 'undefined' ? datetime : "2014-01-01 01:02:03.123456";

var datetime = new Date(datetime).getTime();
var now = new Date().getTime();

if( isNaN(datetime) )
{
    return "";
}

console.log( datetime + " " + now);

if (datetime < now) {
    var milisec_diff = now - datetime;
}else{
    var milisec_diff = datetime - now;
}

var days = Math.floor(milisec_diff / 1000 / 60 / (60 * 24));

var date_diff = new Date( milisec_diff );

return days + "d "+ (date_diff.getHours() - 5) + "h " + (date_diff.getMinutes() - 30) + "m";
}

Export whole database select format as SQL. Now, open that SQL file which you have downloaded using notepad, notepad++ or any editor. You will see all the tables and insert queries of your database. All scripts will be available there.

The simple solution, which no one have mentioned yet, is to just ignore the problem. If I try to use an int as a template type in a function template that expects a container class such as vector or list, then I will get a compile error. Crude and simple, but it solves the problem. The compiler will try to use the type you specify, and if that fails, it generates a compile error.

The only problem with that is that the error messages you get are going to be tricky to read. It is nevertheless a very common way to do this. The standard library is full of function or class templates that expect certain behavior from the template type, and do nothing to check that the types used are valid.

If you want nicer error messages (or if you want to catch cases that wouldn't produce a compiler error, but still don't make sense) you can, depending on how complex you want to make it, use either Boost's static assert or the Boost concept_check library.

With an up-to-date compiler you have a built_in static_assert, which could be used instead.

the complete know how, i have included a example of the triggers and sequence

create table temasforo(
idtemasforo NUMBER(5) PRIMARY KEY,
autor       VARCHAR2(50) NOT NULL,
fecha       DATE DEFAULT (sysdate),
asunto      LONG  );

create sequence temasforo_seq
  start with 1
  increment by 1
  nomaxvalue;

create or replace
trigger temasforo_trigger
  before insert on temasforo
  referencing OLD as old NEW as new
  for each row
  begin
      :new.idtemasforo:=temasforo_seq.nextval;
    end;

Button does not have a value attribute. To get the text of button try:

$('.my_button').click(function() {
     alert($(this).html());
});

I can see that you want to write you own short javascript for this, but have you considered to use Frameworks for HTML manipulation instead? jQuery is my prefered tool for such a task, eventhough its an overkill for your current question as it has SO many extra functionalities.

Have a look at jQuery here

It's still not possible.

Are you rebooting the device into the bootloader and entering fastboot USB on the bootloader menu?

Try

adb reboot bootloader

then look for on screen instructions to enter fastboot mode.

I just tested on Laravel Framework 5.7.19 and the following steps work:

Make sure your .babelrc file is in the root folder of your application, and add the following code:

{
  "plugins": ["@babel/plugin-proposal-class-properties"]
}

Run npm install --save-dev @babel/plugin-proposal-class-properties.

Run npm run watch.

You might want to consider also checking if a value is finite via Double.isFinite(value). Since Java 8 there is a new method in Double class where you can check at once if a value is not NaN and infinity.

/**
 * Returns {@code true} if the argument is a finite floating-point
 * value; returns {@code false} otherwise (for NaN and infinity
 * arguments).
 *
 * @param d the {@code double} value to be tested
 * @return {@code true} if the argument is a finite
 * floating-point value, {@code false} otherwise.
 * @since 1.8
 */
public static boolean isFinite(double d)

You need to multiply your Model matrix. Because that is where model position, scaling and rotation should be (that's why it's called the model matrix).

All you need to do is (see here)

Model = glm::rotate(Model, angle_in_radians, glm::vec3(x, y, z)); // where x, y, z is axis of rotation (e.g. 0 1 0)

Note that to convert from degrees to radians, use glm::radians(degrees)

That takes the Model matrix and applies rotation on top of all the operations that are already in there. The other functions translate and scale do the same. That way it's possible to combine many transformations in a single matrix.

note: earlier versions accepted angles in degrees. This is deprecated since 0.9.6

Model = glm::rotate(Model, angle_in_degrees, glm::vec3(x, y, z)); // where x, y, z is axis of rotation (e.g. 0 1 0)

The above answer only deal with DOM parser (that normally reads the entire file in memory and parse it, what for a big file is a problem), you could use a SAX parser that uses less memory and is faster (anyway that depends on your code).

SAX parser callback some functions when it find a start of element, end of element, attribute, text between elements, etc, so it can parse the document and at the same time you get what you need.

Some example code:

Alternatively, you can use the GitHub project ts-deepcopy, which is also available on npm, to clone your object, or just include the code snippet below.

/**
 * Deep copy function for TypeScript.
 * @param T Generic type of target/copied value.
 * @param target Target value to be copied.
 * @see Source project, ts-deepcopy https://github.com/ykdr2017/ts-deepcopy
 * @see Code pen https://codepen.io/erikvullings/pen/ejyBYg
 */
export const deepCopy = <T>(target: T): T => {
  if (target === null) {
    return target;
  }
  if (target instanceof Date) {
    return new Date(target.getTime()) as any;
  }
  if (target instanceof Array) {
    const cp = [] as any[];
    (target as any[]).forEach((v) => { cp.push(v); });
    return cp.map((n: any) => deepCopy<any>(n)) as any;
  }
  if (typeof target === 'object' && target !== {}) {
    const cp = { ...(target as { [key: string]: any }) } as { [key: string]: any };
    Object.keys(cp).forEach(k => {
      cp[k] = deepCopy<any>(cp[k]);
    });
    return cp as T;
  }
  return target;
};

I think you can use db.collection.distinct(fields,query)

You will be able to get the distinct values in your case for NetworkID.

It should be something like this :

Db.collection.distinct('NetworkID')

In general:

Three "default" textSize values:

 - 14sp
 - 18sp
 - 22sp

These values are defined within the following TextAppearances:

 - TextAppearance.Small
 - TextAppearance.Medium
 - TextAppearance.Large

More information about Typography can be found in the design guidelines

Related to your question:

If you don't set a custom textSize or textAppearance, TextAppearance.Small will be used.

Update: Material design:

New guidelines related to font and typefaces. The standard rule of 14sp remains (body).

Examples how to set textappearances

AppCompat version:

android:textAppearance="@style/TextAppearance.AppCompat.Body"

Lollipop and up version:

android:textAppearance="@android:style/TextAppearance.Material.Body"

Chart.js is quite useful, supporting numerous other types of charts as well.

It can be used both with jQuery and without.

You can do this, I am using

DataTable 1.10.5

using this code:

var versionNo = $.fn.dataTable.version;
alert(versionNo);

This is how I insert new record on my DataTable using row.add (My table has 10 columns), which can also includes HTML tag elements:

function fncInsertNew() {
            var table = $('#tblRecord').DataTable();

            table.row.add([
                    "Tiger Nixon",
                    "System Architect",
                    "$3,120",
                    "2011/04/25",
                    "Edinburgh",
                    "5421",
                    "Tiger Nixon",
                    "System Architect",
                    "$3,120",
                    "<p>Hello</p>"
            ]).draw();
        }

For multiple inserts at the same time, use rows.add instead:

var table = $('#tblRecord').DataTable();

table.rows.add( [ {
        "Tiger Nixon",
        "System Architect",
        "$3,120",
        "2011/04/25",
        "Edinburgh",
        "5421"
    }, {
        "Garrett Winters",
        "Director",
        "$5,300",
        "2011/07/25",
        "Edinburgh",
        "8422"
    }]).draw();

You can use <script>'s defer attribute. It specifies that the script will be executed when the page has finished parsing.

<script defer src="path/to/yourscript.js">

A nice article about this: http://davidwalsh.name/script-defer

Browser support seems pretty good: http://caniuse.com/#search=defer

Another great article about loading JS using defer and async: https://flaviocopes.com/javascript-async-defer/

I was experiencing the same problem, and after a bit of experimentation I found a solution. In my click handler, I needed to stop the event from bubbling up, like so:

$("a.close").on("click", function(e){
  $("#modal").modal("hide");
  e.stopPropagation();
});

You don't need to use regex, LIKE is sufficient:

WHERE my_field LIKE '[a-zA-Z][a-zA-Z]%'

Assuming that by "alphabetical" you mean only latin characters, not anything classified as alphabetical in Unicode.

Note - if your collation is case sensitive, it's important to specify the range as [a-zA-Z]. [a-z] may exclude A or Z. [A-Z] may exclude a or z.

Things have changed since this question was posted, now with new Google Services API, you can prompt users to enable GPS:

https://developers.google.com/places/android-api/current-place

You will need to request ACCESS_FINE_LOCATION permission in your manifest:

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

Also watch this video:

If there is any chance that you will need to search for empty strings,

    a['Names'].str.contains('') 

will NOT work, as it will always return True.

Instead, use

    if '' in a["Names"].values

to accurately reflect whether or not a string is in a Series, including the edge case of searching for an empty string.

Use the Activity Monitor. It's the last toolbar in the top bar. It will show you a list of "Recent Expensive Queries". You can double-click them to see the execution plan, etc.

This is how to open any file:

from os import path

filepath = '...' # your path
file = open(filepath, 'r')

You at least need to add the .java extension to the file name in this line:

javac -cp /home/manish.yadav/Desktop/JCuda-All-0.3.2-bin-linux-x86_64 EnumDevices

From the official faq:

Class names, 'HelloWorldApp', are only accepted if annotation processing is explicitly requested

If you receive this error, you forgot to include the .java suffix when compiling the program. Remember, the command is javac HelloWorldApp.java not javac HelloWorldApp.

Also, in your second javac-example, (in which you actually included .java) you need to include the all required .jar-files needed for compilation.

Things have changed in the last years. The answers above are not valid in all cases any more. Apple is pushing disappearing scrollbars everywhere. Safari, Chrome and even Firefox on MacOs (and iOs) only show scrollbars when actually scrolling — I don't know about current Windows/IE. However there are non-standard ways to style scroll bars on Webkit (IE dropped that a long time ago).

As of Git v2.23.0 (August 2019), git switch is preferred over git checkout when you’re simply switching branches/tags. I’m guessing they did this since git checkout had two functions: for switching branches and for restoring files. So in v2.23.0, they added two new commands, git switch, and git restore, to separate those concerns. I would predict at some point in the future, git checkout will be deprecated.

To switch to a normal branch, use git switch <branch-name>. To switch to a commit-like object, including single commits and tags, use git switch --detach <commitish>, where <commitish> is the tag name or commit number.

The --detach option forces you to recognize that you’re in a mode of “inspection and discardable experiments”. To create a new branch from the commitish you’re switching to, use git switch -c <new-branch> <start-point>.

The cast (int) myobject should just work.

If that gives you an invalid cast exception then it is probably because the variant type isn't VT_I4. My bet is that a variant with VT_I4 is converted into a boxed int, VT_I2 into a boxed short, etc.

When doing a cast on a boxed value type it is only valid to cast it to the type boxed. Foe example, if the returned variant is actually a VT_I2 then (int) (short) myObject should work.

Easiest way to find out is to inspect the returned object and take a look at its type in the debugger. Also make sure that in the interop assembly you have the return value marked with MarshalAs(UnmanagedType.Struct)

you have to split the datetime and then store it with your desired format like dd/MM/yyyy. then you can use this query with between but i have objection using this becasue it will search every single data on your database,so i suggest you can use datediff.

        Dim start = txtstartdate.Text.Trim()
        Dim endday = txtenddate.Text.Trim()
        Dim arr()
        arr = Split(start, "/")
        Dim dt As New DateTime
        dt = New Date(Val(arr(2).ToString), Val(arr(1).ToString), Val(arr(0).ToString))
        Dim arry()
        arry = Split(endday, "/")
        Dim dt2 As New DateTime
        dt2 = New Date(Val(arry(2).ToString), Val(arry(1).ToString), Val(arry(0).ToString))

        qry = "SELECT * FROM [calender] WHERE datediff(day,'" & dt & "',[date])>=0 and datediff(day,'" & dt2 & "',[date])<=0 "

here i have used dd/MM/yyyy format.

Sample code you can use to let Tika take care of container files for you. http://wiki.apache.org/tika/RecursiveMetadata

Form what I can tell, the accepted solution will not work for cases where there are nested zip files. Tika, however will take care of such situations as well.

You will need to inspect the DOM to check this works. Jquery is needed.

$(document).ready(function(){
   var el = document.createElement('script');
   el.type = 'application/ld+json';
   el.text = JSON.stringify({ "@context": "http://schema.org",  "@type": "Recipe", "name": "My recipe name" });

   document.querySelector('head').appendChild(el);
});

In addition to @fareed namrouti's answer,

This should be used if the image has to be browsed from a file input element

<input type="file" name="file" id="file-input"><br/>
image after transform: <br/>
<div id="container"></div>

<script>
    document.getElementById('file-input').onchange = function (e) {
        var image = e.target.files[0];
        window.loadImage(image, function (img) {
            if (img.type === "error") {
                console.log("couldn't load image:", img);
            } else {
                window.EXIF.getData(image, function () {
                    console.log("load image done!");
                    var orientation = window.EXIF.getTag(this, "Orientation");
                    var canvas = window.loadImage.scale(img,
                        {orientation: orientation || 0, canvas: true, maxWidth: 200});
                    document.getElementById("container").appendChild(canvas);
                    // or using jquery $("#container").append(canvas);
                });
            }
        });
    };
</script>

It's very simple. Right click inside the internal browser and click "refresh".

The Java-based Oracle SQL Developer has a plugin module that supports SQL Server. I use it regularly on my Mac. It's free, too.

Here's how to install the SQL Server plugin:

• Run SQL Developer
• go to this menu item: Oracle SQL Developer/Preferences/Database/Third-party JDBC Drivers
• Click help.
• It will have pointers to the JAR files for MySQL, SQL Server, etc.
• The SQL Server JAR file is available at http://sourceforge.net/projects/jtds/files/

As of July 2018 this works perfectly with or without the Facebook app on all the devices.

        PackageManager packageManager = getPackageManager();

        if (packageManager != null) {
            Intent activated = packageManager.getLaunchIntentForPackage("com.facebook.katana");

            if (activated != null) {
                int versionCode = packageManager.getPackageInfo("com.facebook.katana", 0).versionCode;

                if (versionCode >= 3002850) {
                    facebookurl = "fb://page/1548219792xxxxxx";
                }
            } else {
                facebookurl = FACEBOOK_URL;

I know it's been a year since this was asked, but just for people that are going to visit this page I am posting my solution.

By using what @Aldi Unanto suggested here is a more complete answer:

  jQuery('.show_hide').click(function(e) {
    e.preventDefault();
    if (jQuery('.slidingDiv').is(":visible") ) {
      jQuery('.slidingDiv').stop(true,true).hide("slide", { direction: "left" }, 200);
    } else {
      jQuery('.slidingDiv').stop(true,true).show("slide", { direction: "left" }, 200);
    }
  });

First I prevent the link from doing anything on click. Then I add a check if the element is visible or not. When visible I hide it. When hidden I show it. You can change direction to left or right and duration from 200 ms to anything you like.

Edit: I have also added

.stop(true,true)

in order to clearQueue and jumpToEnd. Read about jQuery stop here

It's destroy and destroy_all methods, like

user.destroy
User.find(15).destroy
User.destroy(15)
User.where(age: 20).destroy_all
User.destroy_all(age: 20)

Alternatively you can use delete and delete_all which won't enforce :before_destroy and :after_destroy callbacks or any dependent association options.

User.delete_all(condition: 'value') will allow you to delete records without a primary key

Note: from @hammady's comment, user.destroy won't work if User model has no primary key.

Note 2: From @pavel-chuchuva's comment, destroy_all with conditions and delete_all with conditions has been deprecated in Rails 5.1 - see guides.rubyonrails.org/5_1_release_notes.html

According the w3c spec height refers to the height of the viewable area e.g. on a 1280x1024 pixel resolution monitor 100% height = 1024 pixels.

min-height refers to the total height of the page including content so on a page where the content is bigger than 1024px min-height:100% will stretch to include all of the content.

The other problem then is that padding and border are added to the height and width in most modern browsers except ie6(ie6 is actually quite logical but does not conform to the spec). This is called the box model. So if you specify

min-height: 100%;
padding: 5px; 

It will actually give you 100% + 5px + 5px for the height. To get around this you need a wrapper container.

<style>
    .FullHeight { 
       height: auto !important; /* ie 6 will ignore this */
       height: 100%;            /* ie 6 will use this instead of min-height */
       min-height: 100%;        /* ie 6 will ignore this */
    }

    .Padded {
       padding: 5px;
    }
</style>

<div class="FullHeight">
   <div class="Padded">
      Hello i am padded.
   </div
</div>

you can also do this

$model->hidden1 = 'your value';// better put it on controller
$form->field($model, 'hidden1')->hiddenInput()->label(false);

this is a better option if you set value on controller

$model = new SomeModelName();

if ($model->load(Yii::$app->request->post()) && $model->save()) {
    return $this->redirect(['view', 'id' => $model->group_id]);
 } else {
    $model->hidden1 = 'your value';
    return $this->render('create', [
        'model' => $model,
    ]);
 }

Math.Floor() rounds toward negative infinity

Math.Truncate rounds up or down towards zero.

For example:

Math.Floor(-3.4)     = -4
Math.Truncate(-3.4)  = -3

while

Math.Floor(3.4)     = 3
Math.Truncate(3.4)  = 3

I had a similar problem, but I was getting an error message

cannot execute binary file

I discovered that the filename contained non-ASCII characters. When those were fixed, the script ran fine with ./script.sh.

Better to find cells from gridview instead of static/fix index so it will not generate any problem whenever you will add/remove any columns on gridview.

ASPX:

<asp:GridView ID="GridView1" OnRowDataBound="GridView1_RowDataBound" >
    <Columns>
        <asp:BoundField HeaderText="Date" DataField="CreatedDate" />
    </Columns>
</asp:GridView>

CS:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.Header)
    {
        for (int i = 0; i < e.Row.Cells.Count; i++)
        {
            if (string.Compare(e.Row.Cells[i].Text, "Date", true) == 0)
            {
                e.Row.Cells[i].Text = "Created Date";
            }
        }
    }
}

So I was running 300 PHP processes simulatenously and was getting a rate of between 60 - 90 per second (my process involves 3x queries). I upped it to 400 and this fell to about 40-50 per second. I dropped it to 200 and am back to between 60 and 90!

So my advice to anyone with this problem is experiment with running less than more and see if it improves. There will be less memory and CPU being used so the processes that do run will have greater ability and the speed may improve.

It's a bit worse, I use a calling card for international calls, so its local number in the US + account# (6 digits) + pin (4 digits) + "pause" + what you described above.

I suspect there might be other cases

No, there is no "easy" way. Your best bet would be to do a loop where you first check each previous sibling, then move to the parent node and all of its previous siblings.

You'll need to break the selector into two, 1 to check if the current node could be the top level node in your selector, and 1 to check if it's descendants match.

Edit: This might as well be a plugin. You can use this with any selector in any HTML:

(function($) {
    $.fn.closestPrior = function(selector) {
        selector = selector.replace(/^\s+|\s+$/g, "");
        var combinator = selector.search(/[ +~>]|$/);
        var parent = selector.substr(0, combinator);
        var children = selector.substr(combinator);
        var el = this;
        var match = $();
        while (el.length && !match.length) {
            el = el.prev();
            if (!el.length) {
                var par = el.parent();
                // Don't use the parent - you've already checked all of the previous 
                // elements in this parent, move to its previous sibling, if any.
                while (par.length && !par.prev().length) {
                    par = par.parent();
                }
                el = par.prev();
                if (!el.length) {
                    break;
                }
            }
            if (el.is(parent) && el.find(children).length) {
                match = el.find(children).last();
            }
            else if (el.find(selector).length) {
                match = el.find(selector).last();
            }
        }
        return match;
    }
})(jQuery);

I have a far more simple solution, it is working for me; it is also a workaround but might be usable and you dont have to change your settings. I assume you can use value that will never be there, then you use it on your WHERE clause

DELETE FROM MyTable WHERE MyField IS_NOT_EQUAL AnyValueNoItemOnMyFieldWillEverHave

I don't like that solution either too much, that's why I am here, but it works and it seems better than what it has been answered

To check OleDbConnection State use this:

if (oconn.State == ConnectionState.Open)
{
    oconn.Close();
}

State return the ConnectionState

public override ConnectionState State { get; }

Here are the other ConnectionState enum

public enum ConnectionState
    {
        //
        // Summary:
        //     The connection is closed.
        Closed = 0,
        //
        // Summary:
        //     The connection is open.
        Open = 1,
        //
        // Summary:
        //     The connection object is connecting to the data source. (This value is reserved
        //     for future versions of the product.)
        Connecting = 2,
        //
        // Summary:
        //     The connection object is executing a command. (This value is reserved for future
        //     versions of the product.)
        Executing = 4,
        //
        // Summary:
        //     The connection object is retrieving data. (This value is reserved for future
        //     versions of the product.)
        Fetching = 8,
        //
        // Summary:
        //     The connection to the data source is broken. This can occur only after the connection
        //     has been opened. A connection in this state may be closed and then re-opened.
        //     (This value is reserved for future versions of the product.)
        Broken = 16
    }

Using OLE Query, it's quite simple (e.g. sheetName is Sheet1):

DataTable LoadWorksheetInDataTable(string fileName, string sheetName)
{           
    DataTable sheetData = new DataTable();
    using (OleDbConnection conn = this.returnConnection(fileName))
    {
       conn.Open();
       // retrieve the data using data adapter
       OleDbDataAdapter sheetAdapter = new OleDbDataAdapter("select * from [" + sheetName + "$]", conn);
       sheetAdapter.Fill(sheetData);
       conn.Close();
    }                        
    return sheetData;
}

private OleDbConnection returnConnection(string fileName)
{
    return new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fileName + "; Jet OLEDB:Engine Type=5;Extended Properties=\"Excel 8.0;\"");
}

For newer Excel versions:

return new OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + fileName + ";Extended Properties=Excel 12.0;");

You can also use Excel Data Reader an open source project on CodePlex. Its works really well to export data from Excel sheets.

The sample code given on the link specified:

FileStream stream = File.Open(filePath, FileMode.Open, FileAccess.Read);

//1. Reading from a binary Excel file ('97-2003 format; *.xls)
IExcelDataReader excelReader = ExcelReaderFactory.CreateBinaryReader(stream);
//...
//2. Reading from a OpenXml Excel file (2007 format; *.xlsx)
IExcelDataReader excelReader = ExcelReaderFactory.CreateOpenXmlReader(stream);
//...
//3. DataSet - The result of each spreadsheet will be created in the result.Tables
DataSet result = excelReader.AsDataSet();
//...
//4. DataSet - Create column names from first row
excelReader.IsFirstRowAsColumnNames = true;
DataSet result = excelReader.AsDataSet();

//5. Data Reader methods
while (excelReader.Read())
{
//excelReader.GetInt32(0);
}

//6. Free resources (IExcelDataReader is IDisposable)
excelReader.Close();

Reference: How do I import from Excel to a DataSet using Microsoft.Office.Interop.Excel?

there is another way wich you don't have to overwrite uibModal classes and use them if needed : you call $uibModal.open function with your own size type like "xlg" and then you define a class named "modal-xlg" like below :

.modal-xlg{
   width:1200px;
}

call $uibModal.open as :

 var modalInstance = $uibModal.open({
                ...  
                size: "xlg",
            });

and this will work . because whatever string you pass as size bootstrap will cocant it with "modal-" and this will play the role of class for window.

Since String.Length is an integer (that is an alias for Int32), its size is limited to Int32.MaxValue unicode characters. ;-)

Try this:

@echo off
set run=
tasklist /fi "imagename eq notepad.exe" | find ":" > nul
if errorlevel 1 set run=yes
if "%run%"=="yes" echo notepad is running
if "%run%"=="" echo notepad is not running
pause

I have used this command and it worked for me.

import sys
!{sys.executable} -m pip install xgboost

In my case, spring threw this because i forgot to make an inner class static.

When you found that it doesnt help even adding a no-arg constructor, please check your modifier.

I think allow_url_fopen on your apache server is disabled. you need to trun it on.

kindly change allow_url_fopen = 0 to allow_url_fopen = 1

Don't forget to restart your Apache server after changing it.

I had this problem and tried many different solutions. They didn't work for me although I think this error occurs for a couple of different reasons. My solution is in my answer to this question here:

https://stackoverflow.com/a/15785253/2240058

Its worth a try if nothing else is working for you.

I change upload method with images[] according to @Denmark.

    private function upload_files($path, $title, $files)
    {
        $config = array(
            'upload_path'   => $path,
            'allowed_types' => 'jpg|gif|png',
            'overwrite'     => 1,                       
        );

        $this->load->library('upload', $config);

        $images = array();

        foreach ($files['name'] as $key => $image) {
            $_FILES['images[]']['name']= $files['name'][$key];
            $_FILES['images[]']['type']= $files['type'][$key];
            $_FILES['images[]']['tmp_name']= $files['tmp_name'][$key];
            $_FILES['images[]']['error']= $files['error'][$key];
            $_FILES['images[]']['size']= $files['size'][$key];

            $fileName = $title .'_'. $image;

            $images[] = $fileName;

            $config['file_name'] = $fileName;

            $this->upload->initialize($config);

            if ($this->upload->do_upload('images[]')) {
                $this->upload->data();
            } else {
                return false;
            }
        }

        return $images;
    }

A simple way is:

while (<FILE>) { $document .= $_ }

Another way is to change the input record separator "$/". You can do it locally in a bare block to avoid changing the global record separator.

{
    open(F, "filename");
    local $/ = undef;
    $d = <F>;
}

I think [ ]{4} might work in the example where you need to detect 4 spaces. Same with the rest: [ ]{1}, [ ]{2} and [ ]{3}. If you want to detect an empty string in general, ^[ ]*$ will do.

You're trying to pass file objects as filenames. Try using

infile = '110331_HS1A_1_rtTA.result'
outfile = '2.txt'

at the top of your code.

(Not only does the doubled usage of open() cause that problem with trying to open the file again, it also means that infile and outfile are never closed during the course of execution, though they'll probably get closed once the program ends.)

Try

//re:*[. ='match']

Gson is very usefull for this. easier even. here is my example:

public class Bean {
private String nombre="juan";
private String apellido="machado";
private List<InnerBean> datosCriticos;

class InnerBean
{
    private int edad=12;

}
public Bean() {
    datosCriticos = new ArrayList<>();
    datosCriticos.add(new InnerBean());
}

}

    Bean bean = new Bean();
    Gson gson = new Gson();
    String json =gson.toJson(bean);

out.print(json);

{"nombre":"juan","apellido":"machado","datosCriticos":[{"edad":12}]}

Have to say people if yours vars are empty when using gson it wont build the json for you.Just the

{}

alternative solution with awk and double parenthesis:

FILENAME=file.txt
SIZE=$(du -sb $FILENAME | awk '{ print $1 }')

if ((SIZE<90000)) ; then 
    echo "less"; 
else 
    echo "not less"; 
fi

You can also add hash when page is loading:

location.hash = "noBack";

Then just handle location hash change to add another hash:

$(window).on('hashchange', function() {
    location.hash = "noBack";
});

That makes hash always present and back button tries to remove hash at first. Hash is then added again by "hashchange" handler - so page would never actually can be changed to previous one.

You don't specify which shell (there are many), so I am assuming Bourne Shell, that is I think your script starts with:

#!/bin/sh

Please remember to tag future questions with the shell type, as this will help the community answer your question.

You need to define your functions before you call them. Using ():

process_install()
{
    echo "Performing process_install() commands, using arguments [${*}]..."
}

process_exit()
{
    echo "Performing process_exit() commands, using arguments [${*}]..."
}

Then you can call your functions, just as if you were calling any command:

if [ "$choice" = "true" ]
then
    process_install foo bar
elif [ "$choice" = "false" ]
then
    process_exit baz qux

You may also wish to check for invalid choices at this juncture...

else
    echo "Invalid choice [${choice}]..."
fi

See it run with three different values of ${choice}.

Good luck!

Here is a more general solution:

int increment = 3;
for(int i = 0; i < theData.Length; i += increment)
{
   for(int j = 0; j < increment; j++)
   {
      if(i+j < theData.Length) {
         //theData[i + j] for the current index
      }
   }

}

Replace

f = open(D\\python\\HW\\2_1 - Copy.cp,"r");

by

f = open("D:\\python\\HW\\2_1 - Copy.cp", "r")

1. File path needs to be a string (constant)
2. need colon in Windows file path
3. space after comma for better style
4. ; after statement is allowed but fugly.

Twisted has SSH support : http://www.devshed.com/c/a/Python/SSH-with-Twisted/

The twisted.conch package adds SSH support to Twisted. This chapter shows how you can use the modules in twisted.conch to build SSH servers and clients.

Setting Up a Custom SSH Server

The command line is an incredibly efficient interface for certain tasks. System administrators love the ability to manage applications by typing commands without having to click through a graphical user interface. An SSH shell is even better, as it’s accessible from anywhere on the Internet.

You can use twisted.conch to create an SSH server that provides access to a custom shell with commands you define. This shell will even support some extra features like command history, so that you can scroll through the commands you’ve already typed.

How Do I Do That? Write a subclass of twisted.conch.recvline.HistoricRecvLine that implements your shell protocol. HistoricRecvLine is similar to twisted.protocols.basic.LineReceiver , but with higher-level features for controlling the terminal.

Write a subclass of twisted.conch.recvline.HistoricRecvLine that implements your shell protocol. HistoricRecvLine is similar to twisted.protocols.basic.LineReceiver, but with higher-level features for controlling the terminal.

To make your shell available through SSH, you need to implement a few different classes that twisted.conch needs to build an SSH server. First, you need the twisted.cred authentication classes: a portal, credentials checkers, and a realm that returns avatars. Use twisted.conch.avatar.ConchUser as the base class for your avatar. Your avatar class should also implement twisted.conch.interfaces.ISession , which includes an openShell method in which you create a Protocol to manage the user’s interactive session. Finally, create a twisted.conch.ssh.factory.SSHFactory object and set its portal attribute to an instance of your portal.

Example 10-1 demonstrates a custom SSH server that authenticates users by their username and password. It gives each user a shell that provides several commands.

Example 10-1. sshserver.py

$ ssh admin@localhost -p 2222 
admin@localhost’s password: aaa

>>> Welcome to my test SSH server.  
Commands: clear echo help quit whoami
$ whoami
admin
$ help echo
Echo a string. Usage: echo my line of text
$ echo hello SSH world!
hello SSH world!
$ quit

Connection to localhost closed.

You can use two way:

1: You just keep the necessary columns:

drop_column_list = ["drop_column"]
df = df.select([column for column in df.columns if column not in drop_column_list])  

2: This is the more elegant way.

df = df.drop("col_name")

You should avoid the collect() version, because it will send to the master the complete dataset, it will take a big computing effort!

As the other answers have said, Spring just takes care of it, creating the beans and injecting them as required.

One of the consequences is that bean injection / property setting might occur in a different order to what your XML wiring files would seem to imply. So you need to be careful that your property setters don't do initialization that relies on other setters already having been called. The way to deal with this is to declare beans as implementing the InitializingBean interface. This requires you to implement the afterPropertiesSet() method, and this is where you do the critical initialization. (I also include code to check that important properties have actually been set.)

There is some issue with some language display time ago for example in Arabic there 3 needed formats to display date. I use this functions in my projects hopefully they can help someone (any suggestion or improvement I'll be apperciate :) )

/**

    $date1 = date_create($date1);   
    $date2 = date_create($date2);
    $diff = date_diff( $date1, $date2, $absolute );

    $d = [

I just use this to fix my problem

Assuming you have something like so:

public class MyFirstClass {
   ...
   public ArrayList<Integer> myNumbers()    {
    ArrayList<Integer> numbers = new ArrayList<Integer>();
    numbers.add(5);
    numbers.add(11);
    numbers.add(3);
    return(numbers);
   }
   ...
}

You can call that method like so:

public class MySecondClass {
    ...
    MyFirstClass m1 = new MyFirstClass();
    List<Integer> myList = m1.myNumbers();
    ...
}

Since the method you are trying to call is not static, you will have to create an instance of the class which provides this method. Once you create the instance, you will then have access to the method.

Note, that in the code example above, I used this line: List<Integer> myList = m1.myNumbers();. This can be changed by the following: ArrayList<Integer> myList = m1.myNumbers();. However, it is usually recommended to program to an interface, and not to a concrete implementation, so my suggestion for the method you are using would be to do something like so:

public List<Integer> myNumbers()    {
    List<Integer> numbers = new ArrayList<Integer>();
    numbers.add(5);
    numbers.add(11);
    numbers.add(3);
    return(numbers);
   }

This will allow you to assign the contents of that list to whatever implements the List interface.

I don't think you want an OrderedDict. It sounds like you'd prefer a SortedDict, that is a dict that maintains its keys in sorted order. The sortedcontainers module provides just such a data type. It's written in pure-Python, fast-as-C implementations, has 100% coverage and hours of stress.

Installation is easy with pip:

pip install sortedcontainers

Note that if you can't pip install then you can simply pull the source files from the open-source repository.

Then you're code is simply:

from sortedcontainers import SortedDict
myDic = SortedDict({10: 'b', 3:'a', 5:'c'})
sorted_list = list(myDic.keys())

The sortedcontainers module also maintains a performance comparison with other popular implementations.

Most Android and iPhone apps I have seen use an initial screen or dialog box to ask for credentials. I think it is cumbersome for the user to have to re-enter their name/password often, so storing that info makes sense from a usability perspective.

The advice from the (Android dev guide) is:

In general, we recommend minimizing the frequency of asking for user credentials -- to make phishing attacks more conspicuous, and less likely to be successful. Instead use an authorization token and refresh it.

Where possible, username and password should not be stored on the device. Instead, perform initial authentication using the username and password supplied by the user, and then use a short-lived, service-specific authorization token.

Using the AccountManger is the best option for storing credentials. The SampleSyncAdapter provides an example of how to use it.

If this is not an option to you for some reason, you can fall back to persisting credentials using the Preferences mechanism. Other applications won't be able to access your preferences, so the user's information is not easily exposed.

No. This is not possible. Use something like supervisord to get an ssh server if that's needed. Although, I definitely question the need.

You want to use transform this will return a Series with the index aligned to the df so you can then add it as a new column:

In [74]:

df = pd.DataFrame({'Date': ['2015-05-08', '2015-05-07', '2015-05-06', '2015-05-05', '2015-05-08', '2015-05-07', '2015-05-06', '2015-05-05'], 'Sym': ['aapl', 'aapl', 'aapl', 'aapl', 'aaww', 'aaww', 'aaww', 'aaww'], 'Data2': [11, 8, 10, 15, 110, 60, 100, 40],'Data3': [5, 8, 6, 1, 50, 100, 60, 120]})
?
df['Data4'] = df['Data3'].groupby(df['Date']).transform('sum')
df
Out[74]:
   Data2  Data3        Date   Sym  Data4
0     11      5  2015-05-08  aapl     55
1      8      8  2015-05-07  aapl    108
2     10      6  2015-05-06  aapl     66
3     15      1  2015-05-05  aapl    121
4    110     50  2015-05-08  aaww     55
5     60    100  2015-05-07  aaww    108
6    100     60  2015-05-06  aaww     66

Python opens files almost in the same way as in C:

• r+ Open for reading and writing. The stream is positioned at the beginning of the file.

• a+ Open for reading and appending (writing at end of file). The file is created if it does not exist. The initial file position for reading is at the beginning of the file, but output is appended to the end of the file (but in some Unix systems regardless of the current seek position).

Following solution is working fine.

HTML:

<table>
  <tr>
    <td>
      <input type="button" value="Delete Row" onclick="SomeDeleteRowFunction(this);">
    </td>
  </tr>
  <tr>
    <td>
      <input type="button" value="Delete Row" onclick="SomeDeleteRowFunction(this);">
    </td>
  </tr>
  <tr>
    <td>
      <input type="button" value="Delete Row" onclick="SomeDeleteRowFunction(this);">
    </td>
  </tr>
</table>

JQuery:

function SomeDeleteRowFunction(btndel) {
    if (typeof(btndel) == "object") {
        $(btndel).closest("tr").remove();
    } else {
        return false;
    }
}

Put the table in its own filegroup. You can then use regular SQL Server built in backup to backup the filegroup in which in effect backs up the table.

To backup a filegroup see: https://docs.microsoft.com/en-us/sql/relational-databases/backup-restore/back-up-files-and-filegroups-sql-server

To create a table on a non-default filegroup (its easy) see: Create a table on a filegroup other than the default

Generating your own key from a byte array is easy:

byte[] raw = ...; // 32 bytes in size for a 256 bit key
Key skey = new javax.crypto.spec.SecretKeySpec(raw, "AES");

But creating a 256-bit key isn't enough. If the key generator cannot generate 256-bit keys for you, then the Cipher class probably doesn't support AES 256-bit either. You say you have the unlimited jurisdiction patch installed, so the AES-256 cipher should be supported (but then 256-bit keys should be too, so this might be a configuration problem).

Cipher cipher = Cipher.getInstance("AES");
cipher.init(Cipher.ENCRYPT_MODE, skey);
byte[] encrypted = cipher.doFinal(plainText.getBytes());

A workaround for lack of AES-256 support is to take some freely available implementation of AES-256, and use it as a custom provider. This involves creating your own Provider subclass and using it with Cipher.getInstance(String, Provider). But this can be an involved process.

Give the child component a ref and use $refs to call a method on the child component directly.

html:

<div id="app">
  <child-component ref="childComponent"></child-component>
  <button @click="click">Click</button>  
</div>

javascript:

var ChildComponent = {
  template: '<div>{{value}}</div>',
  data: function () {
    return {
      value: 0
    };
  },
  methods: {
    setValue: function(value) {
        this.value = value;
    }
  }
}

new Vue({
  el: '#app',
  components: {
    'child-component': ChildComponent
  },
  methods: {
    click: function() {
        this.$refs.childComponent.setValue(2.0);
    }
  }
})

For more info, see Vue documentation on refs.

They don't exist in MySQL do they? Just use a temp table:

CREATE PROCEDURE my_proc () BEGIN 

CREATE TEMPORARY TABLE TempTable (myid int, myfield varchar(100)); 
INSERT INTO TempTable SELECT tblid, tblfield FROM Table1; 

/* Do some more stuff .... */

From MySQL here

"You can use the TEMPORARY keyword when creating a table. A TEMPORARY table is visible only to the current connection, and is dropped automatically when the connection is closed. This means that two different connections can use the same temporary table name without conflicting with each other or with an existing non-TEMPORARY table of the same name. (The existing table is hidden until the temporary table is dropped.)"

//Suppose function not taking any parameter means just add the GetAlterConfirmation(function(result) {});
GetAlterConfirmation('test','messageText',function(result) {
                        alert(result);
    }); //Function into document load or any other click event.


function GetAlterConfirmation(titleText, messageText, _callback){
         bootbox.confirm({
                    title: titleText,
                    message: messageText,
                    buttons: {
                        cancel: {
                            label: '<i class="fa fa-times"></i> Cancel'
                        },
                        confirm: {
                            label: '<i class="fa fa-check"></i> Confirm'
                        }
                    },
                    callback: function (result) {
                        return _callback(result); 
                    }
                });

This worked for me in Laravel 5.8

return \Redirect::to('https://bla.com/?yken=KuQxIVTNRctA69VAL6lYMRo0');

Or instead of / you can use

use Redirect;

BT version 2.0 or less - You should be able to pair/bond using a standard PIN code, entered programmatically e.g. 1234 or 0000. This is not very secure but many BT devices do this.

BT version 2.1 or greater - Mode 4 Secure Simple Pairing "just works" model can be used. It uses elliptical encryption (whatever that is) and is very secure but is open to Man In The Middle attacks. Compared to the old '0000' pin code approach it is light years ahead. This doesn't require any user input.

This is according to the Bluetooth specs but what you can use depends on what verson of the Bluetooth standard your stack supports and what API you have.

Which SDKs? If you mean the SDK for Cocoa development, you can check in /Developer/SDKs/ to see which ones you have installed.

If you're looking for the Java SDK version, then open up /Applications/Utilities/Java Preferences. The versions of Java that you have installed are listed there.

On Mac OS X 10.6, though, the only Java version is 1.6.

I was facing same issue and I just started app with new port and everything looks good.

ng serve --port 4201

Best way would be

#include <iostream>                        
using namespace std;                       

int main() {                               
    float celsius;                         
    float fahrenheit;

    cout << "Enter Celsius temperature: "; 
    cin >> celsius;
    fahrenheit = (celsius * 1.8) + 32;// removing division for the confusion
    cout << "Fahrenheit = " << fahrenheit << endl;

    return 0;                             
}

:)

Another possibility is to use the options with data attributes, like this(minimum date 1 week before):

<input class='datepicker' data-date-start-date="-1w">

More info: http://bootstrap-datepicker.readthedocs.io/en/latest/options.html

Some advantages to the second option:

1. You can use this inside onclick to reference the anchor itself (doing the same in option 1 will give you window instead).

2. You can set the href to a non-JS compatible URL to support older browsers (or those that have JS disabled); browsers that support JavaScript will execute the function instead (to stay on the page you have to use onclick="return someFunction();" and return false from inside the function or onclick="return someFunction(); return false;" to prevent default action).

3. I've seen weird stuff happen when using href="javascript:someFunction()" and the function returns a value; the whole page would get replaced by just that value.

Pitfalls

Inline code:

1. Runs in document scope as opposed to code defined inside <script> tags which runs in window scope; therefore, symbols may be resolved based on an element's name or id attribute, causing the unintended effect of attempting to treat an element as a function.

2. Is harder to reuse; delicate copy-paste is required to move it from one project to another.

3. Adds weight to your pages, whereas external code files can be cached by the browser.

You could also write your own parser to pull the URL of all the images and then dynamically create new imageviews and pass in the urls.

For Swift 3.1 and above

let url = NSURL (string: "Your Url")
let requestObj = NSURLRequest(url: url as! URL);
YourWebViewName.loadRequest(requestObj as URLRequest)

Depending on what you want to accomplish within the loop, iterate over one of these instead:

• countries.keySet()
• countries.entrySet()
• countries.values()

Type the command mvn -version directly in your maven directory, you probably haven't added it to your PATH. Here are explained details of how to add maven to your PATH variable (I guess you use Windows because you are talking about CMD).

You can use

insert into <table_name> select <fieldlist> from <tables>

My recyclerview was slow in loading so by reading the stackoverflow.com I changed hardwareAccelerated to "false" then the elevation is not showing in the device. The I changed back to true. It works for me.

Also remember that all info(), error(), and debug() logging calls provide internal documentation within any application.

prodigitalson's answer didn't work for me. I got missing fopen in CURLOPT_FILE more details.

This worked for me, including local urls:

function downloadUrlToFile($url, $outFileName)
{   
    if(is_file($url)) {
        copy($url, $outFileName); 
    } else {
        $options = array(
          CURLOPT_FILE    => fopen($outFileName, 'w'),
          CURLOPT_TIMEOUT =>  28800, // set this to 8 hours so we dont timeout on big files
          CURLOPT_URL     => $url
        );

        $ch = curl_init();
        curl_setopt_array($ch, $options);
        curl_exec($ch);
        curl_close($ch);
    }
}

Encryption has not only cpu, but also some network overhead.

All appender names must be reflected in the root section.
In your case the appender name is EventLogAppender but in the <root> <appender-ref .. section it is named as ConsoleAppender. They need to match.

You can add multiple appenders to your log config but you need to register each of them in the <root> section.

<appender-ref ref="ConsoleAppender" />
<appender-ref ref="EventLogAppender" />

You can also refer to the apache documentation on configuring log4net.

The mainstream is, as other answers here already pointed out, probably going with the Sphinx way so that you can use Sphinx to generate those fancy documents later.

That being said, I personally go with inline comment style occasionally.

def complex(  # Form a complex number
        real=0.0,  # the real part (default 0.0)
        imag=0.0  # the imaginary part (default 0.0)
        ):  # Returns a complex number.
    """Form a complex number.

    I may still use the mainstream docstring notation,
    if I foresee a need to use some other tools
    to generate an HTML online doc later
    """
    if imag == 0.0 and real == 0.0:
        return complex_zero
    other_code()

One more example here, with some tiny details documented inline:

def foo(  # Note that how I use the parenthesis rather than backslash "\"
          # to natually break the function definition into multiple lines.
        a_very_long_parameter_name,
            # The "inline" text does not really have to be at same line,
            # when your parameter name is very long.
            # Besides, you can use this way to have multiple lines doc too.
            # The one extra level indentation here natually matches the
            # original Python indentation style.
            #
            # This parameter represents blah blah
            # blah blah
            # blah blah
        param_b,  # Some description about parameter B.
            # Some more description about parameter B.
            # As you probably noticed, the vertical alignment of pound sign
            # is less a concern IMHO, as long as your docs are intuitively
            # readable.
        last_param,  # As a side note, you can use an optional comma for
                     # your last parameter, as you can do in multi-line list
                     # or dict declaration.
        ):  # So this ending parenthesis occupying its own line provides a
            # perfect chance to use inline doc to document the return value,
            # despite of its unhappy face appearance. :)
    pass

The benefits (as @mark-horvath already pointed out in another comment) are:

• Most importantly, parameters and their doc always stay together, which brings the following benefits:
• Less typing (no need to repeat variable name)
• Easier maintenance upon changing/removing variable. There will never be some orphan parameter doc paragraph after you rename some parameter.
• and easier to find missing comment.

Now, some may think this style looks "ugly". But I would say "ugly" is a subjective word. A more neutual way is to say, this style is not mainstream so it may look less familiar to you, thus less comfortable. Again, "comfortable" is also a subjective word. But the point is, all the benefits described above are objective. You can not achieve them if you follow the standard way.

Hopefully some day in the future, there will be a doc generator tool which can also consume such inline style. That will drive the adoption.

PS: This answer is derived from my own preference of using inline comments whenever I see fit. I use the same inline style to document a dictionary too.

You can use:

  const sha1 = require('sha1');
  const crypt = sha1('Text');
  console.log(crypt);

For install:

  sudo npm install -g sha1
  npm install sha1 --save

This seems much more straight forward to me:

import re

s = 'asdf=5;iwantthis123jasd'
x= re.search('iwantthis',s)
print(s[x.start():x.end()])

You need to give relative or absolute or fixed positioning to your container (#shop) and set its zIndex to say 100.

You also need to give say relative positioning to your elements with the class content and lower zIndex say 97.

Do the above-mentioned with your images too and set their zIndex to 91.

And then position your button higher by setting its position to absolute and zIndex to 95

On newer (for example 8.0.0) the simplest solution is (good choice for a scripted start-up for example):

mysqld --port=23306

I use this here:

Last time I was looking for something like this I found it as an answer to this question.

select get_something('NAME', sys.diutil.int_to_bool(1)) from dual;

It could be some un-initialized function pointer, in particular if you have corrupted memory (then the bogus vtable of C++ bad pointers to invalid objects might give that).

BTW gdb watchpoints & tracepoints, and also valgrind might be useful (if available) to debug such issues. Or some address sanitizer.

subscribe() -Invokes an execution of an Observable and registers Observer handlers for notifications it will emit. -Observable- representation of any set of values over any amount of time.

You just need to add this line to the window there:

exec (your stored proc name) (and possibly add parameters)

What is your stored proc called, and what parameters does it expect?

import re
pattern = re.compile("<(\d{4,5})>")

for i, line in enumerate(open('test.txt')):
    for match in re.finditer(pattern, line):
        print 'Found on line %s: %s' % (i+1, match.group())

A couple of notes about the regex:

• You don't need the ? at the end and the outer (...) if you don't want to match the number with the angle brackets, but only want the number itself
• It matches either 4 or 5 digits between the angle brackets

Update: It's important to understand that the match and capture in a regex can be quite different. The regex in my snippet above matches the pattern with angle brackets, but I ask to capture only the internal number, without the angle brackets.

More about regex in python can be found here : Regular Expression HOWTO

For the purpose of comparing two objects, the simplest way to do this would be to add a unique property to one of the objects at the time you need to compare the objects, check if the property exists in the other and then remove it again. This saves overriding prototypes.

function isSameObject(objectA, objectB) {
   unique_ref = "unique_id_" + performance.now();
   objectA[unique_ref] = true;
   isSame = objectB.hasOwnProperty(unique_ref);
   delete objectA[unique_ref];
   return isSame;
}

object1 = {something:true};
object2 = {something:true};
object3 = object1;

console.log(isSameObject(object1, object2)); //false
console.log(isSameObject(object1, object3)); //true

If a tranformation like allCaps is set, speedplane's approach is buggy. I fixed it, resulting in the following code (sorry, my reputation does not allow me to add this as a comment to speedplane's solution):

import android.content.Context;
import android.graphics.Paint;
import android.util.AttributeSet;
import android.util.TypedValue;
import android.widget.TextView;

public class FontFitTextView extends TextView {

    public FontFitTextView(Context context) {
        super(context);
        initialise();
    }

    public FontFitTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
        initialise();
    }

    private void initialise() {
        mTestPaint = new Paint();
        mTestPaint.set(this.getPaint());
        //max size defaults to the initially specified text size unless it is too small
    }

    /* Re size the font so the specified text fits in the text box
     * assuming the text box is the specified width.
     */
    private void refitText(String text, int textWidth) 
    { 
        if (getTransformationMethod() != null) {
            text = getTransformationMethod().getTransformation(text, this).toString();
        }

        if (textWidth <= 0)
            return;
        int targetWidth = textWidth - this.getPaddingLeft() - this.getPaddingRight();
        float hi = 100;
        float lo = 2;
        final float threshold = 0.5f; // How close we have to be

        mTestPaint.set(this.getPaint());

        while((hi - lo) > threshold) {
            float size = (hi+lo)/2;
            if(mTestPaint.measureText(text) >= targetWidth) 
                hi = size; // too big
            else
                lo = size; // too small
        }
        // Use lo so that we undershoot rather than overshoot
        this.setTextSize(TypedValue.COMPLEX_UNIT_PX, lo);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
    {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
        int parentWidth = MeasureSpec.getSize(widthMeasureSpec);
        int height = getMeasuredHeight();
        refitText(this.getText().toString(), parentWidth);
        this.setMeasuredDimension(parentWidth, height);
    }

    @Override
    protected void onTextChanged(final CharSequence text, final int start, final int before, final int after) {
        refitText(text.toString(), this.getWidth());
    }

    @Override
    protected void onSizeChanged (int w, int h, int oldw, int oldh) {
        if (w != oldw) {
            refitText(this.getText().toString(), w);
      }
    }

    //Attributes
    private Paint mTestPaint;
}

You can use Object.defineProperty on the document object for the referrer property:

Object.defineProperty(document, "referrer", {get : function(){ return "my new referrer"; }});

Unfortunately this will not work on any version of safari <=5, Firefox < 4, Chrome < 5 and Internet Explorer < 9 as it doesn't allow defineProperty to be used on dom objects.

The problem is that when we use application/x-www-form-urlencoded, Spring doesn't understand it as a RequestBody. So, if we want to use this we must remove the @RequestBody annotation.

Then try the following:

@RequestMapping(value = "/{email}/authenticate", method = RequestMethod.POST,
        consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE, 
        produces = {MediaType.APPLICATION_ATOM_XML_VALUE, MediaType.APPLICATION_JSON_VALUE})
public @ResponseBody  Representation authenticate(@PathVariable("email") String anEmailAddress, MultiValueMap paramMap) throws Exception {
   if(paramMap == null && paramMap.get("password") == null) {
        throw new IllegalArgumentException("Password not provided");
    }
    return null;
}

Note that removed the annotation @RequestBody

keytool ships with Android Studio as part of the JRE needed to run Android Studio.

On Windows its: C:\Program Files\Android\Android Studio\jre\bin\keytool.exe

On Mac its: /Applications/Android Studio.app/Contents/jre/jdk/Contents/Home/bin/keytool

Add it to your environment variables then run the keytool command again.

in parent.html:

<script type="text/javascript">
    $(document).ready(function () {
        var output = "data";
        var OpenWindow = window.open("child.html", "mywin", '');
        OpenWindow.dataFromParent = output; // dataFromParent is a variable in child.html
        OpenWindow.init();
    });
</script>

in child.html:

<script type="text/javascript">
    var dataFromParent;    
    function init() {
        document.write(dataFromParent);
    }
</script>

(this was probably better as a comment, but got too long)

So, after reading this I was curious if pre-allocating was actually faster, because in theory it should be. However, this blog gave some tips advising against it http://www.html5rocks.com/en/tutorials/speed/v8/.

So still being unsure, I put it to the test. And as it turns out it seems to in fact be slower.

var time = Date.now();
var temp = [];
for(var i=0;i<100000;i++){
    temp[i]=i;
}
console.log(Date.now()-time);


var time = Date.now();
var temp2 = new Array(100000);
for(var i=0;i<100000;i++){
    temp2[i] = i;
}
console.log(Date.now()-time); 

This code yields the following after a few casual runs:

$ node main.js 
9
16
$ node main.js 
8
14
$ node main.js 
7
20
$ node main.js

$ node main.js

For my blog I use http://hilite.me/ to format source code. It supports lots of formats and outputs rather clean html. But if you have lots of code snippets then you have to do a lot of copy paste. For formatting Python code I've also used Pygments (blog post).

You want to use something like this:

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

The issue you are having is that the gcc compiler is not installed on your Mac. It will be installed if you have installed XCode. You will have to download gcc complier and install it manually. Follow the below link and download it -

https://github.com/downloads/kennethreitz/osx-gcc-installer/GCC-10.7-v2.pkg

I once had this problem installing Ruby 1.9 and I had to compile ruby for myself because Mountain Lion wasn't supported at that time. After installing the package, verify the install by the command gcc.

Multiply the number and then divide it by what you multiplied it by before.

For example,

perc = double.Parse("3.555)*1000;
result = perc/1000

In general, I break lines before operators, and indent the subsequent lines:

Map<long parameterization> longMap
    = new HashMap<ditto>();

String longString = "some long text"
                  + " some more long text";

To me, the leading operator clearly conveys that "this line was continued from something else, it doesn't stand on its own." Other people, of course, have different preferences.

you should install a x server such as XMing. and keep the x server is running. config your putty like this :Connection-Data-SSH-X11-Enable X11 forwarding should be checked. and X display location : localhost:0

For those who troubled with charset

I had very special case that the service provider didn't accept charset, and they refuse to change the substructure to allow it... Unfortunately HttpClient was setting the header automatically through StringContent, and no matter if you pass null or Encoding.UTF8, it will always set the charset...

Today i was on the edge to change the sub-system; moving from HttpClient to anything else, that something came to my mind..., why not use reflection to empty out the "charset"? ... And before i even try it, i thought of a way, "maybe I can change it after initialization", and that worked.

Here's how you can set the exact "application/json" header without "; charset=utf-8".

var jsonRequest = JsonSerializeObject(req, options); // Custom function that parse object to string
var stringContent = new StringContent(jsonRequest, Encoding.UTF8, "application/json");
stringContent.Headers.ContentType.CharSet = null;
return stringContent;

Note: The null value in following won't work, and append "; charset=utf-8"

return new StringContent(jsonRequest, null, "application/json");

EDIT

@DesertFoxAZ suggests that also the following code can be used and works fine. (didn't test it myself, if it work's rate and credit him in comments)

stringContent.Headers.ContentType = new MediaTypeHeaderValue("application/json");

I had this similar error when using wget ..., and after much unfruitful searching in the Internet, I discovered that it was happening when hostnames were being resolved to IPv6 addresses. I discovered this by comparing the outputs of wget ... in two machines, one was resolving to IPv4 and it worked there, the other was resolving to IPv6 and it failed there.

So the solution in my case was to run networksetup -setv6off Wi-Fi on macOS High Sierra 10.13.6. (I discovered this command in this page).

Hope this helps you.

Ancient topic, if someone still stumbles over this--another workaround is to convert via .astype(str) to string before grouping. That will conserve the NaN's.

df = pd.DataFrame({'a': ['1', '2', '3'], 'b': ['4', np.NaN, '6']})
df['b'] = df['b'].astype(str)
df.groupby(['b']).sum()

    a
b   
4   1
6   3
nan 2

I think you should be able to use the HTML escape character (&). They can be found at http://www.theukwebdesigncompany.com/articles/entity-escape-characters.php

In the Macros explorer under samples/accessibility there is an IncreaseTextEditorFontSize and a DecreaseTextEditorFontSize. Bind those to some keyboard shortcuts.

In IntelliJ 14.1.2, I did it like following:

Select File->Project Structure->Modules.

Select + and Import Module and select the directory of your project(or directory where pom exists) and click OK.

Follow through the next flow of screens and after you click Finish, you should see the project alongside your existing one.

Add this in your input element

<input
    action="action"
    onclick="window.history.go(-1); return false;"
    type="submit"
    value="Cancel"
/>

There are many problems in your query.
This is a modified version of your code

string connetionString = null;
string sql = null;

// All the info required to reach your db. See connectionstrings.com
connetionString = "Data Source=UMAIR;Initial Catalog=Air; Trusted_Connection=True;" ;

// Prepare a proper parameterized query 
sql = "insert into Main ([Firt Name], [Last Name]) values(@first,@last)";

// Create the connection (and be sure to dispose it at the end)
using(SqlConnection cnn = new SqlConnection(connetionString))
{
    try
    {
       // Open the connection to the database. 
       // This is the first critical step in the process.
       // If we cannot reach the db then we have connectivity problems
       cnn.Open();

       // Prepare the command to be executed on the db
       using(SqlCommand cmd = new SqlCommand(sql, cnn))
       {
           // Create and set the parameters values 
           cmd.Parameters.Add("@first", SqlDbType.NVarChar).Value = textbox2.text;
           cmd.Parameters.Add("@last", SqlDbType.NVarChar).Value = textbox3.text;

           // Let's ask the db to execute the query
           int rowsAdded = cmd.ExecuteNonQuery();
           if(rowsAdded > 0) 
              MessageBox.Show ("Row inserted!!" + );
           else
              // Well this should never really happen
              MessageBox.Show ("No row inserted");

       }
    }
    catch(Exception ex)
    {
        // We should log the error somewhere, 
        // for this example let's just show a message
        MessageBox.Show("ERROR:" + ex.Message);
    }
}

• The column names contain spaces (this should be avoided) thus you need square brackets around them
• You need to use the using statement to be sure that the connection will be closed and resources released
• You put the controls directly in the string, but this don't work
• You need to use a parametrized query to avoid quoting problems and sqlinjiection attacks
• No need to use a DataAdapter for a simple insert query
• Do not use AddWithValue because it could be a source of bugs (See link below)

Apart from this, there are other potential problems. What if the user doesn't input anything in the textbox controls? Do you have done any checking on this before trying to insert? As I have said the fields names contain spaces and this will cause inconveniences in your code. Try to change those field names.

This code assumes that your database columns are of type NVARCHAR, if not, then use the appropriate SqlDbType enum value.

Please plan to switch to a more recent version of NET Framework as soon as possible. The 1.1 is really obsolete now.

And, about AddWithValue problems, this article explain why we should avoid it. Can we stop using AddWithValue() already?

There is this MarkerClusterer client side utility available for google Map as specified here on Google Map developer Articles, here is brief on what's it's usage:

There are many approaches for doing what you asked for:

• Grid based clustering
• Distance based clustering
• Viewport Marker Management
• Fusion Tables
• Marker Clusterer
• MarkerManager

You can read about them on the provided link above.

Marker Clusterer uses Grid Based Clustering to cluster all the marker wishing the grid. Grid-based clustering works by dividing the map into squares of a certain size (the size changes at each zoom) and then grouping the markers into each grid square.

Before Clustering

After Clustering

I hope this is what you were looking for & this will solve your problem :)

When indexed view is not an option, and quick updates are not necessary, you can create a hack cache table:

select * into cachetablename from myviewname
alter table cachetablename add primary key (columns)
-- OR alter table cachetablename add rid bigint identity primary key
create index...

then sp_rename view/table or change any queries or other views that reference it to point to the cache table.

schedule daily/nightly/weekly/whatnot refresh like

begin transaction
truncate table cachetablename
insert into cachetablename select * from viewname
commit transaction

NB: this will eat space, also in your tx logs. Best used for small datasets that are slow to compute. Maybe refactor to eliminate "easy but large" columns first into an outer view.

You may want to look at how you can use the built-in features of .NET to serialize and deserialize an object into XML, rather than creating a ToXML() method on every class that is essentially just a Data Transfer Object.

I have used these techniques successfully on a couple of projects but don’t have the implementation details handy right now. I will try to update my answer with my own examples sometime later.

Here's a couple of examples that Google returned:

XML Serialization in .NET by Venkat Subramaniam http://www.agiledeveloper.com/articles/XMLSerialization.pdf

How to Serialize and Deserialize an object into XML http://www.dotnetfunda.com/articles/article98.aspx

Customize your .NET object XML serialization with .NET XML attributes http://blogs.microsoft.co.il/blogs/rotemb/archive/2008/07/27/customize-your-net-object-xml-serialization-with-net-xml-attributes.aspx

To ensure a field value is unique you can write

@Column(unique=true)
String username;

The @UniqueConstraint annotation is for annotating multiple unique keys at the table level, which is why you get an error when applying it to a field.

References (JPA TopLink):

• @UniqueConstraint
• @Column

You want sessions if you have data you want to have the data held for longer than one page.

$_GET for just one page.

<a href='page.php?var=data'>Data link</a>

on page.php

<?php
echo $_GET['var'];
?>

will output: data

I added this line to the TextView: android:autoLink="web"
Below is an example of usage in a layout file.

layout.xml sample

    <TextView
        android:id="@+id/txtLostpassword"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:autoLink="email"
        android:gravity="center"
        android:padding="20px"
        android:text="@string/lostpassword"
        android:textAppearance="?android:attr/textAppearanceSmall" />

    <TextView
        android:id="@+id/txtDefaultpassword"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:autoLink="web"
        android:gravity="center"
        android:padding="20px"
        android:text="@string/defaultpassword"
        android:textAppearance="?android:attr/textAppearanceSmall" />

string.xml

<string name="lostpassword">If you lost your password please contact <a href="mailto:[email protected]?Subject=Lost%20Password" target="_top">[email protected]</a></string>

<string name="defaultpassword">User Guide <a href="http://www.cleverfinger.com.au/user-guide/">http://www.cleverfinger.com.au/user-guide/</a></string>

Here's what worked for me. Note: Adding the image within a row introduces some space so I've intentionally used only a div to encapsulate the image.

<div class="container-fluid w-100 h-auto m-0 p-0">  

    <img src="someimg.jpg" class="img-fluid w-100 h-auto p-0 m-0" alt="Patience">           

</div>

So it was a simple fix. Just had to move the ng-click to a scope click handler:

<input id="upload"
    type="file"
    ng-file-select="onFileSelect($files)"
    style="display: none;">

<button type="button"
    ng-click="clickUpload()">Upload</button>



$scope.clickUpload = function(){
    angular.element('#upload').trigger('click');
};

    <groupId>org.springframework.boot</groupId>

    </configuration>

Try this.

Today (2.5 years after this answer) you can safely use Array.forEach. As @ricosrealm suggests, decodeURIComponent was used in this function.

function getJsonFromUrl(url) {
  if(!url) url = location.search;
  var query = url.substr(1);
  var result = {};
  query.split("&").forEach(function(part) {
    var item = part.split("=");
    result[item[0]] = decodeURIComponent(item[1]);
  });
  return result;
}

actually it's not that simple, see the peer-review in the comments, especially:

• hash based routing (@cmfolio)
• array parameters (@user2368055)
• proper use of decodeURIComponent and non-encoded = (@AndrewF)
• non-encoded + (added by me)

For further details, see MDN article and RFC 3986.

Maybe this should go to codereview SE, but here is safer and regexp-free code:

function getJsonFromUrl(url) {
  if(!url) url = location.href;
  var question = url.indexOf("?");
  var hash = url.indexOf("#");
  if(hash==-1 && question==-1) return {};
  if(hash==-1) hash = url.length;
  var query = question==-1 || hash==question+1 ? url.substring(hash) : 
  url.substring(question+1,hash);
  var result = {};
  query.split("&").forEach(function(part) {
    if(!part) return;
    part = part.split("+").join(" "); // replace every + with space, regexp-free version
    var eq = part.indexOf("=");
    var key = eq>-1 ? part.substr(0,eq) : part;
    var val = eq>-1 ? decodeURIComponent(part.substr(eq+1)) : "";
    var from = key.indexOf("[");
    if(from==-1) result[decodeURIComponent(key)] = val;
    else {
      var to = key.indexOf("]",from);
      var index = decodeURIComponent(key.substring(from+1,to));
      key = decodeURIComponent(key.substring(0,from));
      if(!result[key]) result[key] = [];
      if(!index) result[key].push(val);
      else result[key][index] = val;
    }
  });
  return result;
}

This function can parse even URLs like

var url = "?foo%20e[]=a%20a&foo+e[%5Bx%5D]=b&foo e[]=c";
// {"foo e": ["a a",  "c",  "[x]":"b"]}

var obj = getJsonFromUrl(url)["foo e"];
for(var key in obj) { // Array.forEach would skip string keys here
  console.log(key,":",obj[key]);
}
/*
  0 : a a
  1 : c
  [x] : b
*/

For numerical data you have the solution. But it is categorical data, you said. Then life gets a bit more complicated...

Well, first : The amount of association between two categorical variables is not measured with a Spearman rank correlation, but with a Chi-square test for example. Which is logic actually. Ranking means there is some order in your data. Now tell me which is larger, yellow or red? I know, sometimes R does perform a spearman rank correlation on categorical data. If I code yellow 1 and red 2, R would consider red larger than yellow.

So, forget about Spearman for categorical data. I'll demonstrate the chisq-test and how to choose columns using combn(). But you would benefit from a bit more time with Agresti's book : http://www.amazon.com/Categorical-Analysis-Wiley-Probability-Statistics/dp/0471360937

set.seed(1234)
X <- rep(c("A","B"),20)
Y <- sample(c("C","D"),40,replace=T)

table(X,Y)
chisq.test(table(X,Y),correct=F)
# I don't use Yates continuity correction

#Let's make a matrix with tons of columns

Data <- as.data.frame(
          matrix(
            sample(letters[1:3],2000,replace=T),
            ncol=25
          )
        )

# You want to select which columns to use
columns <- c(3,7,11,24)
vars <- names(Data)[columns]

# say you need to know which ones are associated with each other.
out <-  apply( combn(columns,2),2,function(x){
          chisq.test(table(Data[,x[1]],Data[,x[2]]),correct=F)$p.value
        })

out <- cbind(as.data.frame(t(combn(vars,2))),out)

Then you should get :

> out
   V1  V2       out
1  V3  V7 0.8116733
2  V3 V11 0.1096903
3  V3 V24 0.1653670
4  V7 V11 0.3629871

Where V1 and V2 indicate between which variables it goes, and "out" gives the p-value for association. Here all variables are independent. Which you would expect, as I created the data at random.

Save function:

$shopOwner->save()

already do what you want...

Laravel code:

    // If the model already exists in the database we can just update our record
    // that is already in this database using the current IDs in this "where"
    // clause to only update this model. Otherwise, we'll just insert them.
    if ($this->exists)
    {
        $saved = $this->performUpdate($query);
    }

    // If the model is brand new, we'll insert it into our database and set the
    // ID attribute on the model to the value of the newly inserted row's ID
    // which is typically an auto-increment value managed by the database.
    else
    {
        $saved = $this->performInsert($query);
    }

p $eax works as of GDB 7.7.1

As of GDB 7.7.1, the command you've tried works:

set $eax = 0
p $eax
# $1 = 0
set $eax = 1
p $eax
# $2 = 1

This syntax can also be used to select between different union members e.g. for ARM floating point registers that can be either floating point or integers:

p $s0.f
p $s0.u

From the docs:

Any name preceded by ‘$’ can be used for a convenience variable, unless it is one of the predefined machine-specific register names.

and:

You can refer to machine register contents, in expressions, as variables with names starting with ‘$’. The names of registers are different for each machine; use info registers to see the names used on your machine.

But I haven't had much luck with control registers so far: OSDev 2012 http://f.osdev.org/viewtopic.php?f=1&t=25968 || 2005 feature request https://www.sourceware.org/ml/gdb/2005-03/msg00158.html || alt.lang.asm 2013 https://groups.google.com/forum/#!topic/alt.lang.asm/JC7YS3Wu31I

ARM floating point registers

In my case the problem was rendering the output.. So I used the default text if the ajax data is not present yet.

  templateSelection: function(data) {
    return data.name || data.element.innerText;
  }

This function will return the byte size of any UTF-8 string you pass to it.

function byteCount(s) {
    return encodeURI(s).split(/%..|./).length - 1;
}

JavaScript engines are free to use UCS-2 or UTF-16 internally. Most engines that I know of use UTF-16, but whatever choice they made, it’s just an implementation detail that won’t affect the language’s characteristics.

The ECMAScript/JavaScript language itself, however, exposes characters according to UCS-2, not UTF-16.

Source

preg_split the variable containing the text, and iterate over the returned array:

foreach(preg_split("/((\r?\n)|(\r\n?))/", $subject) as $line){
    // do stuff with $line
} 

As stated above there is no boolean class just TrueClass and FalseClass however you can use any object as the subject of if/unless and everything is true except instances of FalseClass and nil

Boolean tests return an instance of the FalseClass or TrueClass

(1 > 0).class #TrueClass

The following monkeypatch to Object will tell you whether something is an instance of TrueClass or FalseClass

class Object
  def boolean?
    self.is_a?(TrueClass) || self.is_a?(FalseClass) 
  end
end

Running some tests with irb gives the following results

?> "String".boolean?
=> false
>> 1.boolean?
=> false
>> Time.now.boolean?
=> false
>> nil.boolean?
=> false
>> true.boolean?
=> true
>> false.boolean?
=> true
>> (1 ==1).boolean?
=> true
>> (1 ==2).boolean?
=> true

<div style='width:200px;margin:0 auto;> sometext or image tag</div>

this works horizontally

open looks in the current working directory, which in your case is ~, since you are calling your script from the ~ directory.

You can fix the problem by either

• cding to the directory containing data.csv before executing the script, or

• by using the full path to data.csv in your script, or

• by calling os.chdir(...) to change the current working directory from within your script. Note that all subsequent commands that use the current working directory (e.g. open and os.listdir) may be affected by this.

For a bandpass filter, ws is a tuple containing the lower and upper corner frequencies. These represent the digital frequency where the filter response is 3 dB less than the passband.

wp is a tuple containing the stop band digital frequencies. They represent the location where the maximum attenuation begins.

gpass is the maximum attenutation in the passband in dB while gstop is the attentuation in the stopbands.

Say, for example, you wanted to design a filter for a sampling rate of 8000 samples/sec having corner frequencies of 300 and 3100 Hz. The Nyquist frequency is the sample rate divided by two, or in this example, 4000 Hz. The equivalent digital frequency is 1.0. The two corner frequencies are then 300/4000 and 3100/4000.

Now lets say you wanted the stopbands to be down 30 dB +/- 100 Hz from the corner frequencies. Thus, your stopbands would start at 200 and 3200 Hz resulting in the digital frequencies of 200/4000 and 3200/4000.

To create your filter, you'd call buttord as

fs = 8000.0
fso2 = fs/2
N,wn = scipy.signal.buttord(ws=[300/fso2,3100/fso2], wp=[200/fs02,3200/fs02],
   gpass=0.0, gstop=30.0)

The length of the resulting filter will be dependent upon the depth of the stop bands and the steepness of the response curve which is determined by the difference between the corner frequency and stopband frequency.

I had the same problem and managed to solve, it simply downgrade your gradle version like this:

dependencies {
    classpath 'com.android.tools.build:gradle:YOUR_GRADLE_VERSION'
}

to

dependencies {
    classpath 'com.android.tools.build:gradle:OLDER_GRADLE_VERSION_THAT_YOUR'
}

for example:

YOUR_GRADLE_VERSION = 3.0.0

OLDER_GRADLE_VERSION_THAT_YOUR = 2.3.2

There is one more reason for such failure which I came to know when mine failed

• You might be working with a lot of data and your RAM is full

This might not apply in this case but it also throws the same error and since this question comes up on top for this error, I have added this answer here.

I will soon released a new version of my app to support to galaxy ace.

You can download here: https://play.google.com/store/apps/details?id=droid.pr.coolflashlightfree

In order to solve your problem you should do this:

this._camera = Camera.open();     
this._camera.startPreview();
this._camera.autoFocus(new AutoFocusCallback() {
public void onAutoFocus(boolean success, Camera camera) {
}
});

Parameters params = this._camera.getParameters();
params.setFlashMode(Parameters.FLASH_MODE_ON);
this._camera.setParameters(params);

params = this._camera.getParameters();
params.setFlashMode(Parameters.FLASH_MODE_OFF);
this._camera.setParameters(params);

don't worry about FLASH_MODE_OFF because this will keep the light on, strange but it's true

to turn off the led just release the camera

EDIT: Please check out Andy's answer as his answer came first and this is solely an extension of his

I know this is an old question, but I think it's worth it to include Array.prototype.sort().

Here's an example from MDN along with the link

var numbers = [4, 2, 5, 1, 3];
numbers.sort(function(a, b) {
  return a - b;
});
console.log(numbers);

// [1, 2, 3, 4, 5]

Luckily it doesn't only work with numbers:

arr.sort([compareFunction])

compareFunction

Specifies a function that defines the sort order. If omitted, the array is sorted according to each character's Unicode code point value, according to the string conversion of each element.

I noticed that you're ordering them by first name:

let playlist = [
    {artist:"Herbie Hancock", title:"Thrust"},
    {artist:"Lalo Schifrin", title:"Shifting Gears"},
    {artist:"Faze-O", title:"Riding High"}
];

// sort by name
playlist.sort((a, b) => {
  if(a.artist < b.artist) { return -1; }
  if(a.artist > b.artist) { return  1; }

  // else names must be equal
  return 0;
});

note that if you wanted to order them by last name you would have to either have a key for both first_name & last_name or do some regex magic, which I can't do XD

Hope that helps :)

What you describe for the second method only gives you a 1D array:

int *board = new int[10];

This just allocates an array with 10 elements. Perhaps you meant something like this:

int **board = new int*[4];
for (int i = 0; i < 4; i++) {
  board[i] = new int[10];
}

In this case, we allocate 4 int*s and then make each of those point to a dynamically allocated array of 10 ints.

So now we're comparing that with int* board[4];. The major difference is that when you use an array like this, the number of "rows" must be known at compile-time. That's because arrays must have compile-time fixed sizes. You may also have a problem if you want to perhaps return this array of int*s, as the array will be destroyed at the end of its scope.

The method where both the rows and columns are dynamically allocated does require more complicated measures to avoid memory leaks. You must deallocate the memory like so:

for (int i = 0; i < 4; i++) {
  delete[] board[i];
}
delete[] board;

I must recommend using a standard container instead. You might like to use a std::array<int, std::array<int, 10> 4> or perhaps a std::vector<std::vector<int>> which you initialise to the appropriate size.

You can use this :

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

public class ConnectMSSQLServer
{
   public void dbConnect(String db_connect_string,
            String db_userid,
            String db_password)
   {
      try {
         Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
         Connection conn = DriverManager.getConnection(db_connect_string,
                  db_userid, db_password);
         System.out.println("connected");
         Statement statement = conn.createStatement();
         String queryString = "select * from sysobjects where type='u'";
         ResultSet rs = statement.executeQuery(queryString);
         while (rs.next()) {
            System.out.println(rs.getString(1));
         }
      } catch (Exception e) {
         e.printStackTrace();
      }
   }

   public static void main(String[] args)
   {
      ConnectMSSQLServer connServer = new ConnectMSSQLServer();
      connServer.dbConnect("jdbc:sqlserver://<hostname>", "<user>",
               "<password>");
   }
}

What does your text file look like?? Each line a record?

You'll have to check out the BULK INSERT statement - that should look something like:

BULK INSERT dbo.YourTableName
FROM 'D:\directory\YourFileName.csv'
WITH
(
  CODEPAGE = '1252',
  FIELDTERMINATOR = ';',
  CHECK_CONSTRAINTS
) 

Here, in my case, I'm importing a CSV file - but you should be able to import a text file just as well.

From the MSDN docs - here's a sample that hopefully works for a text file with one field per row:

BULK INSERT dbo.temp 
   FROM 'c:\temp\file.txt'
   WITH 
      (
         ROWTERMINATOR ='\n'
      )

Seems to work just fine in my test environment :-)

A simple keymap in vim would solve this issue. map viq F”lvf”hh This above command maps viq to the keys to search between quotes. Replace " with any character and create your keymaps. Stick this in vimrc during startup and you should be able to use it everytime.

In most cases, List<T> is more useful. LinkedList<T> will have less cost when adding/removing items in the middle of the list, whereas List<T> can only cheaply add/remove at the end of the list.

LinkedList<T> is only at it's most efficient if you are accessing sequential data (either forwards or backwards) - random access is relatively expensive since it must walk the chain each time (hence why it doesn't have an indexer). However, because a List<T> is essentially just an array (with a wrapper) random access is fine.

List<T> also offers a lot of support methods - Find, ToArray, etc; however, these are also available for LinkedList<T> with .NET 3.5/C# 3.0 via extension methods - so that is less of a factor.

In makefile language $@ means "name of the target", so rm -f $@ translates to rm -f clean.

You need to specify to rm what exactly you want to delete, like rm -f *.o code1 code2

This works for me:

        <TextBox                 
            Text="{Binding Path=UserInput, UpdateSourceTrigger=PropertyChanged}">
            <TextBox.InputBindings>
                <KeyBinding Key="Return" 
                            Command="{Binding Ok}"/>
            </TextBox.InputBindings>
        </TextBox>

Sometimes Web.config of the application ends up in an unconsistent state (duplicate declaration of http handlers, etc) To check which line in config is causing the error open IIS Manager and try to edit the handler mappings..it will display you the error line if there is such an error in web config.

Strangely such errors do not get logged in Event viewer or ULS

I would suggest the following:

String[] parsedInput = str.split("\n"); String firstName = parsedInput[0].split(": ")[1]; String lastName = parsedInput[1].split(": ")[1]; myMap.put(firstName,lastName); 

You can do this with git rebase -i, passing in the revision that you want to use as the 'root':

git rebase -i origin/master

will open an editor window showing all of the commits you have made after the last commit in origin/master. You can reject commits, squash commits into a single commit, or edit previous commits.

There are a few resources that can probably explain this in a better way, and show some other examples:

http://book.git-scm.com/4_interactive_rebasing.html

and

http://gitready.com/advanced/2009/02/10/squashing-commits-with-rebase.html

are the first two good pages I could find.
