document.all works in Chrome now (not sure when since), but I've been missing it the last 20 years.... Simply a shorter method name than the clunky document.getElementById. Not sure if it works in Firefox, those guys never had any desire to be compatible with the existing web, always creating new standards instead of embracing the existing web.

Given that what you want makes sense only when debugging, you could start SQLAlchemy with echo=True, to log all SQL queries. For example:

engine = create_engine(
    "mysql://scott:tiger@hostname/dbname",
    encoding="latin1",
    echo=True,
)

This can also be modified for just a single request:

echo=False – if True, the Engine will log all statements as well as a repr() of their parameter lists to the engines logger, which defaults to sys.stdout. The echo attribute of Engine can be modified at any time to turn logging on and off. If set to the string "debug", result rows will be printed to the standard output as well. This flag ultimately controls a Python logger; see Configuring Logging for information on how to configure logging directly.

If used with Flask, you can simply set

app.config["SQLALCHEMY_ECHO"] = True

to get the same behaviour.

...additionally make sure to use:

mongoose.Promise = Promise;

This sets the mongoose promise to the native ES6 promise. Without this addition I got:

DeprecationWarning: Mongoose: mpromise (mongoose's default promise library) is deprecated, plug in your own promise library instead: http://mongoosejs.com/docs/promises.html

Douglas Crockford says:

type="text/javascript"

This attribute is optional. Since Netscape 2, the default programming language in all browsers has been JavaScript. In XHTML, this attribute is required and unnecessary. In HTML, it is better to leave it out. The browser knows what to do.

In HTML 4.01 and XHTML 1(.1), the type attribute for <script> elements is required.

Yes, that is a good example of a useful closure. The call to warnUser creates the calledCount variable in its scope and returns an anonymous function which is stored in the warnForTamper variable. Because there is still a closure making use of the calledCount variable, it isn't deleted upon the function's exit, so each call to the warnForTamper() will increase the scoped variable and alert the value.

The most common issue I see on Stack Overflow is where someone wants to "delay" use of a variable that is increased upon each loop, but because the variable is scoped then each reference to the variable would be after the loop has ended, resulting in the end state of the variable:

for (var i = 0; i < someVar.length; i++)
    window.setTimeout(function () {
        alert("Value of i was "+i+" when this timer was set" )
    }, 10000);

This would result in every alert showing the same value of i, the value it was increased to when the loop ended. The solution is to create a new closure, a separate scope for the variable. This can be done using an instantly executed anonymous function, which receives the variable and stores its state as an argument:

for (var i = 0; i < someVar.length; i++)
    (function (i) {
        window.setTimeout(function () {
            alert("Value of i was " + i + " when this timer was set")
        }, 10000);
    })(i);

This is an old question yet I find that I also need a solution for this from time to time. The previous answers are all good and works well, I just personally prefer using CTE, for example:

DECLARE @T TABLE (ARIDNR INT, LIEFNR varchar(5)) --table variable for loading sample data
INSERT INTO @T (ARIDNR, LIEFNR) VALUES (1,'A'),(2,'A'),(3,'A'),(1,'B'),(2,'B'); --add your sample data to it
WITH duplicates AS --the CTE portion to find the duplicates
(
    SELECT ARIDNR FROM @T GROUP BY ARIDNR HAVING COUNT(*) > 1
)
SELECT t.* FROM @T t --shows results from main table
INNER JOIN duplicates d on t.ARIDNR = d.ARIDNR --where the main table can be joined to the duplicates CTE

Yields the following results:

1|A
1|B
2|B
2|A

Use document.scrollTop to change the position of the document. Set the scrollTop of the document equal to the bottom of the featured section of your site

The soapAction must passed as a http-header parameter - when used, it's not part of the http-body/payload.

Look here for an example with apache httpclient: http://svn.apache.org/repos/asf/httpcomponents/oac.hc3x/trunk/src/examples/PostSOAP.java

Instead of using re.search use re.findall it will return you all matches in a List. Or you could also use re.finditer (which i like most to use) it will return an Iterator Object and you can just use it to iterate over all found matches.

line = 'bla bla bla<form>Form 1</form> some text...<form>Form 2</form> more text?'
for match in re.finditer('<form>(.*?)</form>', line, re.S):
    print match.group(1)

Using jquery you might do something like this:

// To disable 
$('#targetDiv').children().attr('disabled', 'disabled');

// To enable
$('#targetDiv').children().attr('enabled', 'enabled');

Here's a jsFiddle example: http://jsfiddle.net/monknomo/gLukqygq/

You could also select the target div's children and add a "disabled" css class to them with different visual properties as a callout.

//disable by adding disabled class
$('#targetDiv').children().addClass("disabled");

//enable by removing the disabled class
$('#targetDiv').children().removeClass("disabled");

Try adding this to your source:

It works in most, if not all browsers. Just place it somewhere in your code, and it will act like a breakpoint.

Suppose we want to find the string variable needle in the string variable haystack. There are three gotchas:

1. Internationalized applications should avoid string.toUpperCase and string.toLowerCase. Use a regular expression which ignores case instead. For example, var needleRegExp = new RegExp(needle, "i"); followed by needleRegExp.test(haystack).
2. In general, you might not know the value of needle. Be careful that needle does not contain any regular expression special characters. Escape these using needle.replace(/[-[\]{}()*+?.,\\^$|#\s]/g, "\\$&");.
3. In other cases, if you want to precisely match needle and haystack, just ignoring case, make sure to add "^" at the start and "$" at the end of your regular expression constructor.

Taking points (1) and (2) into consideration, an example would be:

var haystack = "A. BAIL. Of. Hay.";
var needle = "bail.";
var needleRegExp = new RegExp(needle.replace(/[-[\]{}()*+?.,\\^$|#\s]/g, "\\$&"), "i");
var result = needleRegExp.test(haystack);
alert(result);

Lazy loading images using above mentioned plugins uses conventional way of attaching listener to scroll events or by making use of setInterval and is highly non-performant as each call to getBoundingClientRect() forces the browser to re-layout the entire page and will introduce considerable jank to your website.

Use Lozad.js (just 569 bytes with no dependencies), which uses InteractionObserver to lazy load images performantly.

NSTimeInterval diff = [date2 timeIntervalSinceDate:date1]; // in seconds

where date1 and date2 are NSDate's.

Also, note the definition of NSTimeInterval:

typedef double NSTimeInterval;

you can try typescript's For :

selectChildren(data , $event){
   let parentChecked : boolean = data.checked;
   for(let o of this.hierarchicalData){
      for(let child of o){
         child.checked = parentChecked;
      }
   }
}

you're better off reading a line and then doing a split.

File file = new File("path/to/file");
String words[]; // I miss C
String line;
HashMap<String, String> hm = new HashMap<>();
try (BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(file), "UTF-8")))
{
    while((line = br.readLine() != null)){
        words = line.split("\\s");
        if (hm.containsKey(words[0])){
                System.out.println("Found duplicate ... handle logic");
        }
        hm.put(words[0],words[1]); //if index==0 is ur key
    }

} catch (FileNotFoundException e) {
        e.printStackTrace();
} catch (IOException e) {
        e.printStackTrace();
}

• Checkout a working copy of the repository (or at least the subdirectory that you want to add the files to): svn checkout https://example.org/path/to/repo/bleh
• Copy the files over there.
• svn add file1 file2...
• svn commit

I am not aware of a quicker option.

Note: if you are on the same machine as your Subversion repository, the URL can use the file: specifier with a path in place of https: in the svn checkout command. For example svn checkout file:///path/to/repo/bleh.

PS. as pointed out in the comments and other answers, you can use something like svn import . <URL> if you want to recursively import everything in the current directory. With this option, however, you can't skip over some of the files; it's all or nothing.

To get selected item, you have to use SELECTEDITEM property of comboBox. And since this is an Object, if you wanna assign it to a string, you have to convert it to string, by using ToString() method:

string myItem = comboBox1.SelectedItem.ToString(); //this does the trick

I like to use:

myString = Regex.Replace(myString, @"\s+", " ");

Since it will catch runs of any kind of whitespace (e.g. tabs, newlines, etc.) and replace them with a single space.

Try this:

<img v-bind:src="'/media/avatars/' + joke.avatar" /> 

Don't forget single quote around your path string. also in your data check you have correctly defined image variable.

joke: {
  avatar: 'image.jpg'
}

If you are attempting to share a static variable for, by example, increasing it across other instances, something like this script works fine:

# -*- coding: utf-8 -*-

        self.name = ''
        self.document = ''
        self.id = Worker.id
        Worker.id += 1

    def __str__(self):
        return u"{}.- {} {}".format(self.id, self.name, self.document).encode('utf8')


class Workers:
    def __init__(self):
        self.list = []

    def add(self, name, doc):
        worker = Worker()
        worker.name = name
        worker.document = doc
        self.list.append(worker)


if __name__ == "__main__":
    workers = Workers()
    for item in (('Fiona', '0009898'), ('Maria', '66328191'), ("Sandra", '2342184'), ('Elvira', '425872')):
        workers.add(item[0], item[1])
    for worker in workers.list:

If you're using Rails and ActiveAdmin, this is going to be your problem: https://github.com/seyhunak/twitter-bootstrap-rails/issues/450 Basically, a conflict with active_admin.js

This is the solution: https://stackoverflow.com/a/11745446/264084 (Karen's answer) tldr: Move active_admin assets into the "vendor" directory.

First use this Namespace:

using System.Drawing;

Add this anywhere on your form:

listBox.DrawMode = DrawMode.OwnerDrawFixed;
listBox.DrawItem += listBox_DrawItem;

Here is the Event Handler:

private void listBox_DrawItem(object sender, DrawItemEventArgs e)
{
     e.DrawBackground();

     Graphics g = e.Graphics;
     g.FillRectangle(new SolidBrush(Color.White), e.Bounds);
     ListBox lb = (ListBox)sender;
     g.DrawString(lb.Items[e.Index].ToString(), e.Font, new SolidBrush(Color.Black), new PointF(e.Bounds.X, e.Bounds.Y));

     e.DrawFocusRectangle();

I was going through same issue in React-Native where API response & reject weren't updating states

apiCall().then(function(resp) { this.setState({data: resp}) // wasn't updating }

I solved the problem by changing function with the arrow function

apiCall().then((resp) => {
    this.setState({data: resp}) // rendering the view as expected
}

For me, it was a binding issue. Using arrow functions solved it because arrow function doesn't create its's own this, its always bounded to its outer context where it comes from

This can happen also because of a change in the password and since Git Credential Manager caches it, so if that's the case 1. Open Credential Manager in Windows 2. Search for your GIT credential and reset it to the new password.

Add a StringBuilder extension method.

    return sb;

then use:

yourStringBuilder.RemoveLast(",");

function setSelectValue (id, val) {
    document.getElementById(id).value = val;

This post is now nearly 5 years old! Python-2.7 will stop receiving official updates from python.org in 2020. Also, Python-3.7 has been released. Check out Python-Future on how to make your Python-2 code compatible with Python-3. For updating conda, the documentation now recommends using conda update --all in each of your conda environments to update all packages and the Python executable for that version. Also, since they changed their name to Anaconda, I don't know if the Windows registry keys are still the same.

There have been no updates to Python(x,y) since June of 2015, so I think it's safe to assume it has been abandoned.

As @cxw comments below, these answers are for the same bit-versions, and by bit-version I mean 64-bit vs. 32-bit. For example, these answers would apply to updating from 64-bit Python-2.7.10 to 64-bit Python-2.7.11, ie: the same bit-version. While it is possible to install two different bit versions of Python together, it would require some hacking, so I'll save that exercise for the reader. If you don't want to hack, I suggest that if switching bit-versions, remove the other bit-version first.

• Anaconda and MiniConda can be used with an existing Python installation by disabling the options to alter the Windows PATH and Registry. After extraction, create a symlink to conda in your bin or install conda from PyPI. Then create another symlink called conda-activate to activate in the Anaconda/Miniconda root bin folder. Now Anaconda/Miniconda is just like Ruby RVM. Just use conda-activate root to enable Anaconda/Miniconda.
• Portable Python is no longer being developed or maintained.

TL;DR

• Using Anaconda or miniconda, then just execute conda update --all to keep each conda environment updated,
• same major version of official Python (e.g. 2.7.5), just install over old (e.g. 2.7.4),
• different major version of official Python (e.g. 3.3), install side-by-side with old, set paths/associations to point to dominant (e.g. 2.7), shortcut to other (e.g. in BASH $ ln /c/Python33/python.exe python3).

The answer depends:

1. If OP has 2.7.x and wants to install newer version of 2.7.x, then

   • if using MSI installer from the official Python website, just install over old version, installer will issue warning that it will remove and replace the older version; looking in "installed programs" in "control panel" before and after confirms that the old version has been replaced by the new version; newer versions of 2.7.x are backwards compatible so this is completely safe and therefore IMHO multiple versions of 2.7.x should never necessary.
   • if building from source, then you should probably build in a fresh, clean directory, and then point your path to the new build once it passes all tests and you are confident that it has been built successfully, but you may wish to keep the old build around because building from source may occasionally have issues. See my guide for building Python x64 on Windows 7 with SDK 7.0.
   • if installing from a distribution such as Python(x,y), see their website. Python(x,y) has been abandoned. I believe that updates can be handled from within Python(x,y) with their package manager, but updates are also included on their website. I could not find a specific reference so perhaps someone else can speak to this. Similar to ActiveState and probably Enthought, Python (x,y) clearly states it is incompatible with other installations of Python:

     It is recommended to uninstall any other Python distribution before installing Python(x,y)

   • Enthought Canopy uses an MSI and will install either into Program Files\Enthought or home\AppData\Local\Enthought\Canopy\App for all users or per user respectively. Newer installations are updated by using the built in update tool. See their documentation.
   • ActiveState also uses an MSI so newer installations can be installed on top of older ones. See their installation notes.

     Other Python 2.7 Installations On Windows, ActivePython 2.7 cannot coexist with other Python 2.7 installations (for example, a Python 2.7 build from python.org). Uninstall any other Python 2.7 installations before installing ActivePython 2.7.

   • Sage recommends that you install it into a virtual machine, and provides a Oracle VirtualBox image file that can be used for this purpose. Upgrades are handled internally by issuing the sage -upgrade command.

   • Anaconda can be updated by using the conda command:

     conda update --all
     

     Anaconda/Miniconda lets users create environments to manage multiple Python versions including Python-2.6, 2.7, 3.3, 3.4 and 3.5. The root Anaconda/Miniconda installations are currently based on either Python-2.7 or Python-3.5.

     Anaconda will likely disrupt any other Python installations. Installation uses MSI installer. [UPDATE: 2016-05-16] Anaconda and Miniconda now use .exe installers and provide options to disable Windows PATH and Registry alterations.

     Therefore Anaconda/Miniconda can be installed without disrupting existing Python installations depending on how it was installed and the options that were selected during installation. If the .exe installer is used and the options to alter Windows PATH and Registry are not disabled, then any previous Python installations will be disabled, but simply uninstalling the Anaconda/Miniconda installation should restore the original Python installation, except maybe the Windows Registry Python\PythonCore keys.

     Anaconda/Miniconda makes the following registry edits regardless of the installation options: HKCU\Software\Python\ContinuumAnalytics\ with the following keys: Help, InstallPath, Modules and PythonPath - official Python registers these keys too, but under Python\PythonCore. Also uninstallation info is registered for Anaconda\Miniconda. Unless you select the "Register with Windows" option during installation, it doesn't create PythonCore, so integrations like Python Tools for Visual Studio do not automatically see Anaconda/Miniconda. If the option to register Anaconda/Miniconda is enabled, then I think your existing Python Windows Registry keys will be altered and uninstallation will probably not restore them.

   • WinPython updates, I think, can be handled through the WinPython Control Panel.
   • PortablePython is no longer being developed. It had no update method. Possibly updates could be unzipped into a fresh directory and then App\lib\site-packages and App\Scripts could be copied to the new installation, but if this didn't work then reinstalling all packages might have been necessary. Use pip list to see what packages were installed and their versions. Some were installed by PortablePython. Use easy_install pip to install pip if it wasn't installed.

2. If OP has 2.7.x and wants to install a different version, e.g. <=2.6.x or >=3.x.x, then installing different versions side-by-side is fine. You must choose which version of Python (if any) to associate with *.py files and which you want on your path, although you should be able to set up shells with different paths if you use BASH. AFAIK 2.7.x is backwards compatible with 2.6.x, so IMHO side-by-side installs is not necessary, however Python-3.x.x is not backwards compatible, so my recommendation would be to put Python-2.7 on your path and have Python-3 be an optional version by creating a shortcut to its executable called python3 (this is a common setup on Linux). The official Python default install path on Windows is

   • C:\Python33 for 3.3.x (latest 2013-07-29)
   • C:\Python32 for 3.2.x
   • &c.
   • C:\Python27 for 2.7.x (latest 2013-07-29)
   • C:\Python26 for 2.6.x
   • &c.

3. If OP is not updating Python, but merely updating packages, they may wish to look into virtualenv to keep the different versions of packages specific to their development projects separate. Pip is also a great tool to update packages. If packages use binary installers I usually uninstall the old package before installing the new one.

I hope this clears up any confusion.

Installing from RPM is generally better, because:

• you can install and uninstall (properly) python3.
• the installation time is way faster. If you work in a cloud environment with multiple VMs, compiling python3 on each VMs is not acceptable.

Solution 1: Red Hat & EPEL repositories

Red Hat has added through the EPEL repository:

• Python 3.4 for CentOS 6
• Python 3.6 for CentOS 7

[EPEL] How to install Python 3.4 on CentOS 6

sudo yum install -y epel-release
sudo yum install -y python34

# Install pip3
sudo yum install -y python34-setuptools  # install easy_install-3.4
sudo easy_install-3.4 pip

You can create your virtualenv using pyvenv:

pyvenv /tmp/foo

[EPEL] How to install Python 3.6 on CentOS 7

With CentOS7, pip3.6 is provided as a package :)

sudo yum install -y epel-release
sudo yum install -y python36 python36-pip

You can create your virtualenv using pyvenv:

python3.6 -m venv /tmp/foo

If you use the pyvenv script, you'll get a WARNING:

$ pyvenv-3.6 /tmp/foo
WARNING: the pyenv script is deprecated in favour of `python3.6 -m venv`

Solution 2: IUS Community repositories

The IUS Community provides some up-to-date packages for RHEL & CentOS. The guys behind are from Rackspace, so I think that they are quite trustworthy...

https://ius.io/

Check the right repo for you here:

You can add super privilege using phpmyadmin:

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

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

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

After executing above code, end it with:

mysql> FLUSH PRIVILEGES;

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

Select web development tools when you install the visual studio 2013. Then it will work properly and show the asp.net web applicaton.

If you are still inside the vi editor, you might be in a different mode from the one you want. Hit ESC a couple of times (until it rings or flashes) and then "i" to enter INSERT mode or "a" to enter APPEND mode (they are the same, just start before or after current character).

If you are back at the command prompt, make sure you can locate the file, then navigate to that directory and perform the mentioned "vi helloWorld.txt". Once you are in the editor, you'll need to check the vi reference to know how to perform the editions you want (you may want to google "vi reference" or "vi cheat sheet").

Once the edition is done, hit ESC again, then type :wq to save your work or :q! to quit without saving.

For quick reference, here you have a text-based cheat sheet.

If you don't know how many columns you are going to have, the declaration

table-layout: fixed

along with not setting any column widths, would imply that browsers divide the total width evenly - no matter what.

That can also be the problem with this approach, if you use this, you should also consider how overflow is to be handled.

When I were trying install librosa package with pip (pip install librosa), this error were appeared:

ERROR: Cannot uninstall 'llvmlite'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

I tried to remove llvmlite, but pip uninstall could not remove it. So, I used capability of ignore of pip by this code:

pip install librosa --ignore-installed llvmlite

Indeed, you can use this rule for ignoring a package you don't want to consider:

pip install {package you want to install} --ignore-installed {installed package you don't want to consider}

When your path starts with a root dir i.e. C:\ in windows or / in Unix or in java resources path, it is considered to be an absolute path. Everything else is relative, so

new File("test.txt") is the same as new File("./test.txt")

new File("test/../test.txt") is the same as new File("./test/../test.txt")

The major difference between getAbsolutePath and getCanonicalPath is that the first one concatenates a parent and a child path, so it may contain dots: .. or .. getCanonicalPath will always return the same path for a particular file.

Note: File.equals uses an abstract form of a path (getAbsolutePath) to compare files, so this means that two File objects for the same might not be equal and Files are unsafe to use in collections like Map or Set.

Your @POST method should be accepting a JSON object instead of a string. Jersey uses JAXB to support marshaling and unmarshaling JSON objects (see the jersey docs for details). Create a class like:

@XmlRootElement
public class MyJaxBean {
    @XmlElement public String param1;
    @XmlElement public String param2;
}

Then your @POST method would look like the following:

@POST @Consumes("application/json")
@Path("/create")
public void create(final MyJaxBean input) {
    System.out.println("param1 = " + input.param1);
    System.out.println("param2 = " + input.param2);
}

This method expects to receive JSON object as the body of the HTTP POST. JAX-RS passes the content body of the HTTP message as an unannotated parameter -- input in this case. The actual message would look something like:

POST /create HTTP/1.1
Content-Type: application/json
Content-Length: 35
Host: www.example.com

{"param1":"hello","param2":"world"}

Using JSON in this way is quite common for obvious reasons. However, if you are generating or consuming it in something other than JavaScript, then you do have to be careful to properly escape the data. In JAX-RS, you would use a MessageBodyReader and MessageBodyWriter to implement this. I believe that Jersey already has implementations for the required types (e.g., Java primitives and JAXB wrapped classes) as well as for JSON. JAX-RS supports a number of other methods for passing data. These don't require the creation of a new class since the data is passed using simple argument passing.

HTML <FORM>

The parameters would be annotated using @FormParam:

@POST
@Path("/create")
public void create(@FormParam("param1") String param1,
                   @FormParam("param2") String param2) {
    ...
}

The browser will encode the form using "application/x-www-form-urlencoded". The JAX-RS runtime will take care of decoding the body and passing it to the method. Here's what you should see on the wire:

POST /create HTTP/1.1
Host: www.example.com
Content-Type: application/x-www-form-urlencoded;charset=UTF-8
Content-Length: 25

param1=hello&param2=world

The content is URL encoded in this case.

If you do not know the names of the FormParam's you can do the following:

@POST @Consumes("application/x-www-form-urlencoded")
@Path("/create")
public void create(final MultivaluedMap<String, String> formParams) {
    ...
}

HTTP Headers

You can using the @HeaderParam annotation if you want to pass parameters via HTTP headers:

@POST
@Path("/create")
public void create(@HeaderParam("param1") String param1,
                   @HeaderParam("param2") String param2) {
    ...
}

Here's what the HTTP message would look like. Note that this POST does not have a body.

POST /create HTTP/1.1
Content-Length: 0
Host: www.example.com
param1: hello
param2: world

I wouldn't use this method for generalized parameter passing. It is really handy if you need to access the value of a particular HTTP header though.

HTTP Query Parameters

This method is primarily used with HTTP GETs but it is equally applicable to POSTs. It uses the @QueryParam annotation.

@POST
@Path("/create")
public void create(@QueryParam("param1") String param1,
                   @QueryParam("param2") String param2) {
    ...
}

Like the previous technique, passing parameters via the query string does not require a message body. Here's the HTTP message:

POST /create?param1=hello&param2=world HTTP/1.1
Content-Length: 0
Host: www.example.com

You do have to be particularly careful to properly encode query parameters on the client side. Using query parameters can be problematic due to URL length restrictions enforced by some proxies as well as problems associated with encoding them.

HTTP Path Parameters

Path parameters are similar to query parameters except that they are embedded in the HTTP resource path. This method seems to be in favor today. There are impacts with respect to HTTP caching since the path is what really defines the HTTP resource. The code looks a little different than the others since the @Path annotation is modified and it uses @PathParam:

@POST
@Path("/create/{param1}/{param2}")
public void create(@PathParam("param1") String param1,
                   @PathParam("param2") String param2) {
    ...
}

The message is similar to the query parameter version except that the names of the parameters are not included anywhere in the message.

POST /create/hello/world HTTP/1.1
Content-Length: 0
Host: www.example.com

This method shares the same encoding woes that the query parameter version. Path segments are encoded differently so you do have to be careful there as well.

As you can see, there are pros and cons to each method. The choice is usually decided by your clients. If you are serving FORM-based HTML pages, then use @FormParam. If your clients are JavaScript+HTML5-based, then you will probably want to use JAXB-based serialization and JSON objects. The MessageBodyReader/Writer implementations should take care of the necessary escaping for you so that is one fewer thing that can go wrong. If your client is Java based but does not have a good XML processor (e.g., Android), then I would probably use FORM encoding since a content body is easier to generate and encode properly than URLs are. Hopefully this mini-wiki entry sheds some light on the various methods that JAX-RS supports.

Note: in the interest of full disclosure, I haven't actually used this feature of Jersey yet. We were tinkering with it since we have a number of JAXB+JAX-RS applications deployed and are moving into the mobile client space. JSON is a much better fit that XML on HTML5 or jQuery-based solutions.

The problem is the padding of the font on the textview. Just add to your textview:

android:includeFontPadding="false"

First, you'll need to add session_start() at the top of any page that you wish to use SESSION variables on.

Also, you should check to make sure the variable is set first before using it:

if(isset($_SESSION['SESS_fname'])){
    echo $_SESSION['SESS_fname'];
}

Or, simply:

echo (isset($_SESSION['SESS_fname']) ? $_SESSION['SESS_fname'] : "Visitor");

If you have two or more selects and use Steve McLenithan's answer, try to replace the first line with:

$('#CHOSENINPUTFIELDID_chosen > div > div input').autocomplete({

not remove suffix: _chosen

If the long string to multiple lines confuses you. Then you may install mz-tools addin which is a freeware and has the utility which splits the line for you.

Download Mz-tools

If your string looks like below

SqlQueryString = "Insert into Employee values(" & txtEmployeeNo.Value & "','" & txtContractStartDate.Value & "','" & txtSeatNo.Value & "','" & txtFloor.Value & "','" & txtLeaves.Value & "')"

Simply select the string > right click on VBA IDE > Select MZ-tools > Split Lines

ROUND(time_to_sec((TIMEDIFF(NOW(), "2015-06-10 20:15:00"))) / 60);

Replace the following code in this path

Path :

App_Start => WebApiConfig.cs

Code:

config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{action}/{id}/{Param}",
            defaults: new { id = RouteParameter.Optional,
                            Param = RouteParameter.Optional }
                          );

Here is Bjarne Stroustrup's wordings,

In C++, the definition of NULL is 0, so there is only an aesthetic difference. I prefer to avoid macros, so I use 0. Another problem with NULL is that people sometimes mistakenly believe that it is different from 0 and/or not an integer. In pre-standard code, NULL was/is sometimes defined to something unsuitable and therefore had/has to be avoided. That's less common these days.

If you have to name the null pointer, call it nullptr; that's what it's called in C++11. Then, "nullptr" will be a keyword.

In case you have one of the following cases:

• error: InvalidArgumentError: input_X:Y is both fed and fetched
• case of multiple inputs

You need to do the following changes:

• add filter out for input layers in outputs variable
• minnor change on functors loop

Minimum example:

from keras.engine.input_layer import InputLayer
inp = model.input
outputs = [layer.output for layer in model.layers if not isinstance(layer, InputLayer)]
functors = [K.function(inp + [K.learning_phase()], [x]) for x in outputs]
layer_outputs = [fun([x1, x2, xn, 1]) for fun in functors]

Use this in web.config:

<sessionState 

  timeout="20" 
/>

All solutions based on array_keys don't work for mixed arrays. Solution is simple:

echo array_search($needle,array_keys($haystack), true);

From php.net: If the third parameter strict is set to TRUE then the array_search() function will search for identical elements in the haystack. This means it will also perform a strict type comparison of the needle in the haystack, and objects must be the same instance.

Originally we used no-cache many years ago and did run into some problems with stale content with certain browsers... Don't remember the specifics unfortunately.

We had since settled on JUST the use of no-store. Have never looked back or had a single issue with stale content by any browser or intermediaries since.

This space is certainly dominated by reality of implementations vs what happens to have been written in various RFCs. Many proxies in particular tend to think they do a better job of "improving performance" by replacing the policy they are supposed to be following with their own.

It's been quite a while, but this may satisfy you :

Public MyVariable as Integer: MyVariable = 123

It's a bit ugly since you have to retype the variable name, but it's on one line.

Object objectToGet = ...
Map<Object, Object> map = new HashMap<Object, Object>(set.size());
for (Object o : set) {
    map.put(o, o);
}
Object objectFromSet = map.get(objectToGet);

If you only do one get this will not be very performing because you will loop over all your elements but when performing multiple retrieves on a big set you will notice the difference.

You can stop a query which is being processed by this

Find the Id of the query process by => show processlist;

Then => kill id;

I think this could be done in a much simpler way:

1. Find the locator for the Month (use Firebug/Firepath)
2. This is probably a Select element, use Selenium to select Month
3. Do the same for Year
4. Click by linkText "31" or whatever date you want to click

So code would look something like this:

WebElement month = driver.findElement(month combo locator);
Select monthCombo = new Select(month);
monthCombo.selectByVisibleText("March");

WebElement year = driver.findElement(year combo locator);
Select yearCombo = new Select(year);
yearCombo.selectByVisibleText("2015");

driver.click(By.linkText("31"));

This won't work if the date picker dropdowns are not Select, but most of the ones I've seen are individual elements (select, links, etc.)

#include <stdlib.h>

int main()
{
    int x;
    x = rand(6);
    printf("%d", x);
}

Especially as a beginner, you should ask your compiler to print every warning about bad code that it can generate. Modern compilers know lots of different warnings which help you to program better. For example, when you compile this program with the GNU C Compiler:

$ gcc -W -Wall rand.c
rand.c: In function `main':
rand.c:5: error: too many arguments to function `rand'
rand.c:6: warning: implicit declaration of function `printf'

You get two warnings here. The first one says that the rand function only takes zero arguments, not one as you tried. To get a random number between 0 and n, you can use the expression rand() % n, which is not perfect but ok for small n. The resulting random numbers are normally not evenly distributed; smaller values are returned more often.

The second warning tells you that you are calling a function that the compiler doesn't know at that point. You have to tell the compiler by saying #include <stdio.h>. Which include files are needed for which functions is not always simple, but asking the Open Group specification for portable operating systems works in many cases: http://www.google.com/search?q=opengroup+rand.

These two warnings tell you much about the history of the C programming language. 40 years back, the definition of a function didn't include the number of parameters or the types of the parameters. It was also ok to call an unknown function, which in most cases worked. If you want to write code today, you should not rely on these old features but instead enable your compiler's warnings, understand the warnings and then fix them properly.

Instagram developer console has provided the solution for it. https://www.instagram.com/developer/endpoints/

To use this in PHP, here is the code snippet,

/**
**
** Add this code snippet after your first curl call
** assume the response of the first call is stored in $userdata
** $access_token have your access token
*/

$maximumNumberOfPost = 33; // it can be 20, depends on your instagram application
$no_of_images = 50 // Enter the number of images you want

if ($no_of_images > $maximumNumberOfPost) {

    $ImageArray = [];
    $next_url = $userdata->pagination->next_url;
    while ($no_of_images > $maximumNumberOfPost) {
           $originalNumbersOfImage = $no_of_images;
           $no_of_images = $no_of_images - $maximumNumberOfPost;
           $next_url = str_replace("count=" . $originalNumbersOfImage, "count=" . $no_of_images, $next_url);
           $chRepeat = curl_init();
           curl_setopt_array($chRepeat, [
                             CURLOPT_URL => $next_url,
                             CURLOPT_HTTPHEADER => [
                                    "Authorization: Bearer $access_token"
                              ],
                              CURLOPT_RETURNTRANSFER => true
                            ]);
            $userRepeatdata = curl_exec($chRepeat);
            curl_close($chRepeat);
            if ($userRepeatdata) {
                      $userRepeatdata = json_decode($userRepeatdata);
                      $next_url = $userRepeatdata->pagination->next_url;
                     if (isset($userRepeatdata->data) && $userRepeatdata->data) {
                          $ImageArray = $userRepeatdata->data;
                   }
           }
    }

}

all i found solution for whatever you all get the exception like.. org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[]]..

the problem with bulid path of the jars..

To over come this problem.. place all jars in "WebContent/lib" whatever you need to in your project. i hope it will useful to you...

The only thing that worked for me is this:

In project.properties, I changed:

cordova.system.library.1=com.android.support:support-v4:+ to cordova.system.library.1=com.android.support:support-v4:20.+

    extension UITableView {
        /// Reloads a table view without losing track of what was selected.
        func reloadDataSavingSelections() {
            let selectedRows = indexPathsForSelectedRows

            reloadData()

            if let selectedRow = selectedRows {
                for indexPath in selectedRow {
                    selectRow(at: indexPath, animated: false, scrollPosition: .none)
                }
            }
        }
    }

tableView.reloadDataSavingSelections()

You'll have to do this in two steps:

1. Give your JAR a groupId, artifactId and version and add it to your repository.

If you don't have an internal repository, and you're just trying to add your JAR to your local repository, you can install it as follows, using any arbitrary groupId/artifactIds:

mvn install:install-file -DgroupId=com.stackoverflow... -DartifactId=yourartifactid... -Dversion=1.0 -Dpackaging=jar -Dfile=/path/to/jarfile

You can also deploy it to your internal repository if you have one, and want to make this available to other developers in your organization. I just use my repository's web based interface to add artifacts, but you should be able to accomplish the same thing using mvn deploy:deploy-file ....

2. Update dependent projects to reference this JAR.

Then update the dependency in the pom.xml of the projects that use the JAR by adding the following to the element:

<dependencies>
    ...
    <dependency>
        <groupId>com.stackoverflow...</groupId>
        <artifactId>artifactId...</artifactId>
        <version>1.0</version>
    </dependency>
    ...
</dependencies>

A header (.h, .hpp, ...) file contains

• Class definitions ( class X { ... }; )
• Inline function definitions ( inline int get_cpus() { ... } )
• Function declarations ( void help(); )
• Object declarations ( extern int debug_enabled; )

A source file (.c, .cpp, .cxx) contains

• Function definitions ( void help() { ... } or void X::f() { ... } )
• Object definitions ( int debug_enabled = 1; )

However, the convention that headers are named with a .h suffix and source files are named with a .cpp suffix is not really required. One can always tell a good compiler how to treat some file, irrespective of its file-name suffix ( -x <file-type> for gcc. Like -x c++ ).

Source files will contain definitions that must be present only once in the whole program. So if you include a source file somewhere and then link the result of compilation of that file and then the one of the source file itself together, then of course you will get linker errors, because you have those definitions now appear twice: Once in the included source file, and then in the file that included it. That's why you had problems with including the .cpp file.

I had the same problem, except I have a table with 2 billion rows, so the log file would grow to no end if I did this, even with the recovery model set to Bulk-Logging:

insert into newtable select * from oldtable

So I operate on blocks of data. This way, if the transfer is interupted, you just restart it. Also, you don't need a log file as big as the table. You also seem to get less tempdb I/O, not sure why.

set identity_insert newtable on
DECLARE @StartID bigint, @LastID bigint, @EndID bigint
select @StartID = isNull(max(id),0) + 1
from newtable

select @LastID = max(ID)
from oldtable

while @StartID < @LastID
begin
    set @EndID = @StartID + 1000000

    insert into newtable (FIELDS,GO,HERE)
    select FIELDS,GO,HERE from oldtable (NOLOCK)
    where id BETWEEN @StartID AND @EndId

    set @StartID = @EndID + 1
end
set identity_insert newtable off
go

You might need to change how you deal with IDs, this works best if your table is clustered by ID.

The problem is the linker is looking for libmagic.so but you only have libmagic.so.1

A quick hack is to symlink libmagic.so.1 to libmagic.so

Apparently match_parent is :

• NOT OK for views directly under ConstraintLayout
• OK for views nested inside of views that are directly under ConstraintLayout

So if you need your views to function as match_parent, then:

1. Direct children of ConstraintLayout should use 0dp
2. Nested elements (eg, grandchild to ConstraintLayout) can use match_parent

Example:

<android.support.constraint.ConstraintLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:paddingBottom="16dp">

    <android.support.design.widget.TextInputLayout
        android:id="@+id/phoneNumberInputLayout"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent">

        <android.support.design.widget.TextInputEditText
            android:id="@+id/phoneNumber"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"/>

    </android.support.design.widget.TextInputLayout>

This Works

function saveBase64AsFile(base64, fileName) {
    var link = document.createElement("a");
    document.body.appendChild(link);
    link.setAttribute("type", "hidden");
    link.href = "data:text/plain;base64," + base64;
    link.download = fileName;
    link.click();  
    document.body.removeChild(link);
}

Based on the answer above but with some changes

So I realize this is kind of old, but after much Googling, I couldn't find an answer I was happy with, so I came up with my own solution for breaking a FOR loop that immediately stops iteration, and thought I'd share it.

It requires the loop to be in a separate file, and exploits a bug in CMD error handling to immediately crash the batch processing of the loop file when redirecting the STDOUT of DIR to STDIN.

MainFile.cmd

ECHO Simple test demonstrating loop breaking.
ECHO.
CMD /C %~dp0\LOOP.cmd
ECHO.
ECHO After LOOP
PAUSE

LOOP.cmd

FOR /L %%A IN (1,1,10) DO (
    ECHO %%A
    IF %%A EQU 3 DIR >&0 2>NUL  )
)

When run, this produces the following output. You'll notice that both iteration and execution of the loop stops when %A = 3.

:>MainFile.cmd

:>ECHO Simple test demonstrating loop breaking.
Simple test demonstrating loop breaking.

:>ECHO.


:>CMD /C Z:\LOOP.cmd

:>FOR /L %A IN (1 1 10) DO (
ECHO %A
 IF %A EQU 3 DIR         1>&0 2>NUL
)

:>(
ECHO 1
 IF 1 EQU 3 DIR          1>&0 2>NUL
)
1

:>(
ECHO 2
 IF 2 EQU 3 DIR          1>&0 2>NUL
)
2

:>(
ECHO 3
 IF 3 EQU 3 DIR          1>&0 2>NUL
)
3

:>ECHO.


:>ECHO After LOOP
After LOOP

:>PAUSE
Press any key to continue . . .

If you need to preserve a single variable from the loop, have the loop ECHO the result of the variable, and use a FOR /F loop in the MainFile.cmd to parse the output of the LOOP.cmd file.

Example (using the same LOOP.cmd file as above):

MainFile.cmd

@ECHO OFF
ECHO.
ECHO Simple test demonstrating loop breaking.
ECHO.
FOR /F "delims=" %%L IN ('CMD /C %~dp0\LOOP.cmd') DO SET VARIABLE=%%L
ECHO After LOOP
ECHO.
ECHO %VARIABLE%
ECHO.
PAUSE

Output:

:>MainFile.cmd

Simple test demonstrating loop breaking.

After LOOP

3

Press any key to continue . . .

If you need to preserve multiple variables, you'll need to redirect them to temporary files as shown below.

MainFile.cmd

@ECHO OFF
ECHO.
ECHO Simple test demonstrating loop breaking.
ECHO.
CMD /C %~dp0\LOOP.cmd
ECHO After LOOP
ECHO.
SET /P VARIABLE1=<%TEMP%\1
SET /P VARIABLE2=<%TEMP%\2
ECHO %VARIABLE1%
ECHO %VARIABLE2%
ECHO.
PAUSE

LOOP.cmd

@ECHO OFF
FOR /L %%A IN (1,1,10) DO (
    IF %%A EQU 1 ECHO ONE >%TEMP%\1
    IF %%A EQU 2 ECHO TWO >%TEMP%\2
    IF %%A EQU 3 DIR >&0 2>NUL
)

Output:

:>MainFile.cmd

Simple test demonstrating loop breaking.

After LOOP

ONE
TWO

Press any key to continue . . .

I hope others find this useful for breaking loops that would otherwise take too long to exit due to continued iteration.

This is what I use in my application:

static void Main()
{
  bool mutexCreated = false;
  System.Threading.Mutex mutex = new System.Threading.Mutex( true, @"Local\slimCODE.slimKEYS.exe", out mutexCreated );

  if( !mutexCreated )
  {
    if( MessageBox.Show(
      "slimKEYS is already running. Hotkeys cannot be shared between different instances. Are you sure you wish to run this second instance?",
      "slimKEYS already running",
      MessageBoxButtons.YesNo,
      MessageBoxIcon.Question ) != DialogResult.Yes )
    {
      mutex.Close();
      return;
    }
  }

  // The usual stuff with Application.Run()

  mutex.Close();
}

I want columns One and Two to shrink/grow to fit rather than being fixed.

Have you tried: flex-basis: auto

or this:

flex: 1 1 auto, which is short for:

• flex-grow: 1 (grow proportionally)
• flex-shrink: 1 (shrink proportionally)
• flex-basis: auto (initial size based on content size)

or this:

main > section:first-child {
    flex: 1 1 auto;
    overflow-y: auto;
}

main > section:nth-child(2) {
    flex: 1 1 auto;
    overflow-y: auto;
}

main > section:last-child {
    flex: 20 1 auto;
    display: flex;
    flex-direction: column;  
}

For any javadoc (not just the ones available for download) you can use the DownThemAll addon for Firefox with a suitable renaming mask, for example:

*subdirs*/*name*.*ext*

https://addons.mozilla.org/en-us/firefox/addon/downthemall/

https://www.downthemall.org/main/install-it/downthemall-3-0-7/

Edit: It's possible to use some older versions of the DownThemAll add-on with Pale Moon browser.

First set position of the parent DIV to relative (specifying the offset, i.e. left, top etc. is not necessary) and then apply position: absolute to the child DIV with the offset you want.
It's simple and should do the trick well.

On HTML5 the scrollamount and the scrolldelay attributes do not work. They are depricated attributes.

you need to place the opening brace after main , not before it

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

int main(void)
{

If you are going to use ps and grep then you should do it this way:

ps aux|grep r[u]by

Those square brackets will cause grep to skip the line for the grep command itself. So to use this in a script do:

output=`ps aux|grep r\[u\]by`
set -- $output
pid=$2
kill $pid
sleep 2
kill -9 $pid >/dev/null 2>&1

The backticks allow you to capture the output of a comand in a shell variable. The set -- parses the ps output into words, and $2 is the second word on the line which happens to be the pid. Then you send a TERM signal, wait a couple of seconds for ruby to to shut itself down, then kill it mercilessly if it still exists, but throw away any output because most of the time kill -9 will complain that the process is already dead.

I know that I have used this without the backslashes before the square brackets but just now I checked it on Ubuntu 12 and it seems to require them. This probably has something to do with bash's many options and the default config on different Linux distros. Hopefully the [ and ] will work anywhere but I no longer have access to the servers where I know that it worked without backslash so I cannot be sure.

One comment suggests grep-v and that is what I used to do, but then when I learned of the [] variant, I decided it was better to spawn one fewer process in the pipeline.

a simple example under a multi-class setting to illustrate

suppose you have 4 classes (onehot encoded) and below is just one prediction

true_label = [0,1,0,0] predicted_label = [0,0,1,0]

when using categorical_crossentropy, the accuracy is just 0 , it only cares about if you get the concerned class right.

however when using binary_crossentropy, the accuracy is calculated for all classes, it would be 50% for this prediction. and the final result will be the mean of the individual accuracies for both cases.

it is recommended to use categorical_crossentropy for multi-class(classes are mutually exclusive) problem but binary_crossentropy for multi-label problem.

Actually these only work when the window isn't scrolled at all from the top left position.
You have to subtract the window scroll values to get an offset that's useful for repositioning elements so they stay on the page:

var offset = $('#whatever').offset();

offset.right = ($(window).width() + $(window).scrollLeft()) - (offset.left + $('#whatever').outerWidth(true));
offset.bottom = ($(window).height() + $(window).scrollTop()) - (offset.top + $('#whatever').outerHeight(true));

This solution might be easier. But it does require a higher API version(23). simply add this code to your toolbar in XML:

<Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:minHeight="?android:attr/actionBarSize"
    android:background="?android:attr/colorPrimary"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    android:popupTheme="@style/ThemeOverlay.AppCompat.Light"
    android:titleTextColor="#ffffffff" />

I think this original question indirectly points to a general recommendation that run-time null-pointer check is still needed, even though @NonNull is used. Refer to the following link:

Java 8's new Type Annotations

In the above blog, it is recommended that:

Optional Type Annotations are not a substitute for runtime validation Before Type Annotations, the primary location for describing things like nullability or ranges was in the javadoc. With Type annotations, this communication comes into the bytecode in a way for compile-time verification. Your code should still perform runtime validation.

What you are looking for is called Geocoding.

Google provides a Geocoding Web Service which should do what you're looking for. You will be able to do geocoding on your server.

JSON Example:

http://maps.google.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA

XML Example:

http://maps.google.com/maps/api/geocode/xml?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA

Edit:

Please note that this is now a deprecated method and you must provide your own Google API key to access this data.

Firstly: The >>> code you see in python examples is a way to indicate that it is Python code. It's used to separate Python code from output. Like this:

>>> 4+5
9

Here we see that the line that starts with >>> is the Python code, and 9 is what it results in. This is exactly how it looks if you start a Python interpreter, which is why it's done like that.

You never enter the >>> part into a .py file.

That takes care of your syntax error.

Secondly, ctypes is just one of several ways of wrapping Python libraries. Other ways are SWIG, which will look at your Python library and generate a Python C extension module that exposes the C API. Another way is to use Cython.

They all have benefits and drawbacks.

SWIG will only expose your C API to Python. That means you don't get any objects or anything, you'll have to make a separate Python file doing that. It is however common to have a module called say "wowza" and a SWIG module called "_wowza" that is the wrapper around the C API. This is a nice and easy way of doing things.

Cython generates a C-Extension file. It has the benefit that all of the Python code you write is made into C, so the objects you write are also in C, which can be a performance improvement. But you'll have to learn how it interfaces with C so it's a little bit extra work to learn how to use it.

ctypes have the benefit that there is no C-code to compile, so it's very nice to use for wrapping standard libraries written by someone else, and already exists in binary versions for Windows and OS X.

I don't agree with the accepted answer that the lack of electron prevents VSC on Android.

Electron is really the desktop equivelent of projects like Apache Cordova or Adobe PhoneGap (but Electron is much less efficient and will presumably give way to solutions much closer to Cordova/PhoneGap when possible - it is already being worked on eg. here.)

API's would need to be mapped from their electron equivelents, and many of the plug-ins will have their own issues (but Android is reasonably flexible about allowing stuff like Python compared to iOS) so it is doable.

On the other hand, the demand for an Android version of VSC probably comes from people using the new Chromebooks that support Android, and there is already a solution for ChromeOS using crouton, available here.

GitHub is svn compatible so you can use svn ls

svn ls https://github.com/user/repository.git/branches/master/

BitBucket supports git archive so you can download tar archive and list archived files. It is not very efficient but works:

git archive [email protected]:repository HEAD directory | tar -t

I had the same problem. To fix it in Jboss 7 AS, I copy the oracle driver jar file to Jboss module folder. Example: ../jboss-as-7.1.1.Final/modules/org/hibernate/main.

You also need to change "module.xml"

<module xmlns="urn:jboss:module:1.1" name="org.hibernate">
<resources>
    <resource-root path="hibernate-core-4.0.1.Final.jar"/>
    <resource-root path="hibernate-commons-annotations-4.0.1.Final.jar"/>
    <resource-root path="hibernate-entitymanager-4.0.1.Final.jar"/>
    <resource-root path="hibernate-infinispan-4.0.1.Final.jar"/>
    <resource-root path="ojdbc6.jar"/>
</resources>

This function creates a temporary form, then send data using jQuery :

function postToIframe(data,url,target){
    $('body').append('<form action="'+url+'" method="post" target="'+target+'" id="postToIframe"></form>');
    $.each(data,function(n,v){
        $('#postToIframe').append('<input type="hidden" name="'+n+'" value="'+v+'" />');
    });
    $('#postToIframe').submit().remove();
}

target is the 'name' attr of the target iFrame, and data is a JS object :

data={last_name:'Smith',first_name:'John'}

a = ['it']
b = ['was']
c = ['annoying']

a.extend(b)
a.extend(c)

# a now equals ['it', 'was', 'annoying']

You can convert a number to ASCII in java. example converting a number 1 (base is 10) to ASCII.

char k = Character.forDigit(1, 10);
System.out.println("Character: " + k);
System.out.println("Character: " + ((int) k));

Output:

Character: 1
Character: 49

You're looking for the <iframe> tag, or, better yet, a server-side templating language.

I was having the same problem but only with a few machines. I found that using Invoke-Command to run the same command on the remote server worked.

So instead of:

Get-WmiObject win32_SystemEnclosure -ComputerName $hostname -Authentication Negotiate

Use this:

Invoke-Command -ComputerName $hostname -Authentication Negotiate -ScriptBlock {Get-WmiObject win32_SystemEnclosure}

Paresh Mayani's answer is mostly correct. Simply use a Broadcast Intent to let the system and all the other apps choose in what way the content is going to be shared.

To share text use the following code:

String message = "Text I want to share.";
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("text/plain");
share.putExtra(Intent.EXTRA_TEXT, message);

startActivity(Intent.createChooser(share, "Title of the dialog the system will open"));

I solved this problem by programmatically creating the Labels and Textfields, and then Command-Dragged from the little empty circles on the left of the code to the components on the Storyboard. To illustrate my point: I wrote @IBOutlet weak var HelloLabel: UILabel!, and then pressed Command and dragged the code into the component on the storyboard.

I was having the issue after select the deny when it asks for permission

After some search I got it fixed by restarting the system.

This problem can occur if a class tries to get value of a non-existent key in web.config.

For example, the class has a static variable ClientID

private static string ClientID = System.Configuration.ConfigurationSettings.AppSettings["GoogleCalendarApplicationClientID"].ToString();

but the web.config doesn't contain the 'GoogleCalendarApplicationClientID' key, then the error will be thrown on any static function call or any class instance creation

InverseProperty in EF Core makes the solution easy and clean.

InverseProperty

So the desired solution would be:

public class Team
{
    [Key]
    public int TeamId { get; set;} 
    public string Name { get; set; }

    [InverseProperty(nameof(Match.HomeTeam))]
    public ICollection<Match> HomeMatches{ get; set; }

    [InverseProperty(nameof(Match.GuestTeam))]
    public ICollection<Match> AwayMatches{ get; set; }
}


public class Match
{
    [Key]
    public int MatchId { get; set; }

    [ForeignKey(nameof(HomeTeam)), Column(Order = 0)]
    public int HomeTeamId { get; set; }
    [ForeignKey(nameof(GuestTeam)), Column(Order = 1)]
    public int GuestTeamId { get; set; }

    public float HomePoints { get; set; }
    public float GuestPoints { get; set; }
    public DateTime Date { get; set; }

    public Team HomeTeam { get; set; }
    public Team GuestTeam { get; set; }
}

SELECT  name
FROM    orders,company
WHERE   orderID = 1
        AND companyID IN (attachedCompanyIDs)

attachedCompanyIDs is a scalar value which is cast into INT (type of companyID).

The cast only returns numbers up to the first non-digit (a comma in your case).

Thus,

companyID IN ('1,2,3') = companyID IN (CAST('1,2,3' AS INT)) = companyID IN (1)

In PostgreSQL, you could cast the string into array (or store it as an array in the first place):

SELECT  name
FROM    orders
JOIN    company
ON      companyID = ANY (('{' | attachedCompanyIDs | '}')::INT[])
WHERE   orderID = 1

and this would even use an index on companyID.

Unfortunately, this does not work in MySQL since the latter does not support arrays.

You may find this article interesting (see #2):

• 10 things in MySQL (that won’t work as expected)

Update:

If there is some reasonable limit on the number of values in the comma separated lists (say, no more than 5), so you can try to use this query:

SELECT  name
FROM    orders
CROSS JOIN
        (
        SELECT  1 AS pos
        UNION ALL
        SELECT  2 AS pos
        UNION ALL
        SELECT  3 AS pos
        UNION ALL
        SELECT  4 AS pos
        UNION ALL
        SELECT  5 AS pos
        ) q
JOIN    company
ON      companyID = CAST(NULLIF(SUBSTRING_INDEX(attachedCompanyIDs, ',', -pos), SUBSTRING_INDEX(attachedCompanyIDs, ',', 1 - pos)) AS UNSIGNED)

You can add properties dynamically using some of the options below:

In you example:

var data = {
    'PropertyA': 1,
    'PropertyB': 2,
    'PropertyC': 3
};

You can define a property with a dynamic value in the next two ways:

data.key = value;

or

data['key'] = value;

Even more..if your key is also dynamic you can define using the Object class with:

Object.defineProperty(data, key, withValue(value));

where data is your object, key is the variable to store the key name and value is the variable to store the value.

I hope this helps!

Yes, but don't - escaping forward slashes is a good thing. When using JSON inside <script> tags it's necessary as a </script> anywhere - even inside a string - will end the script tag.

Depending on where the JSON is used it's not necessary, but it can be safely ignored.

See the query below (assumed @dt1 >= @dt2);

Declare @dt1 datetime = '2013-7-3'
Declare @dt2 datetime = '2013-5-2'

select abs(DATEDIFF(DD, @dt2, @dt1)) Days,
case when @dt1 >= @dt2
    then case when DAY(@dt2)<=DAY(@dt1)
        then Convert(varchar, DATEDIFF(MONTH, @dt2, @dt1)) + CONVERT(varchar, ' Month(s) ') + Convert(varchar, DAY(@dt1)-DAY(@dt2)) + CONVERT(varchar, 'Day(s).')
        else Convert(varchar, DATEDIFF(MONTH, @dt2, @dt1)-1) + CONVERT(varchar, ' Month(s) ') + convert(varchar, abs(DATEDIFF(DD, @dt1, DateAdd(Month, -1, @dt1))) - (DAY(@dt2)-DAY(@dt1))) + CONVERT(varchar, 'Day(s).')
    end
    else 'See asumption: @dt1 must be >= @dt2'
end In_Months_Days

Returns:

Days | In_Months_Days

62   |   2 Month(s) 1Day(s).

According to the documentation, you should be able to switch back and forth like this:

In [2]: %matplotlib inline 
In [3]: plot(...)

In [4]: %matplotlib qt  # wx, gtk, osx, tk, empty uses default
In [5]: plot(...) 

and that will pop up a regular plot window (a restart on the notebook may be necessary).

I hope this helps.

Since the most answer here suggests time_ago_in_words.

Instead of using :

<%= time_ago_in_words(comment.created_at) %>

In Rails, prefer:

<abbr class="timeago" title="<%= comment.created_at.getutc.iso8601 %>">
  <%= comment.created_at.to_s %>
</abbr>

along with a jQuery library http://timeago.yarp.com/, with code:

$("abbr.timeago").timeago();

Main advantage: caching

     if(integer>>31)
     {
     /*CONVERTING 2's complement value to normal value*/    
     integer=~integer+1;

    printf("\n count =%d ascii=%s ",count,ascii);

If you have a checkbox in your html something like:

<input id="conducted" type = "checkbox" name="party" value="0">

and you want to add an EventListener to this checkbox using javascript, in your associated js file, you can do as follows:

checkbox = document.getElementById('conducted');

checkbox.addEventListener('change', e => {

    if(e.target.checked){
        //do something
    }

});

there is component ready to use (rc5 compatible) ng2-steps which uses Compiler to inject component to step container and service for wiring everything together (data sync)

    import { Directive , Input, OnInit, Compiler , ViewContainerRef } from '@angular/core';

import { StepsService } from './ng2-steps';

@Directive({
  selector:'[ng2-step]'
})
export class StepDirective implements OnInit{

  @Input('content') content:any;
  @Input('index') index:string;
  public instance;

  constructor(
    private compiler:Compiler,
    private viewContainerRef:ViewContainerRef,
    private sds:StepsService
  ){}

  ngOnInit(){
    //Magic!
    this.compiler.compileComponentAsync(this.content).then((cmpFactory)=>{
      const injector = this.viewContainerRef.injector;
      this.viewContainerRef.createComponent(cmpFactory, 0,  injector);
    });
  }

}

I faced a similar kind of issue while using a custom object as a key in Treemap. Whenever you are using a custom object as a key in hashmap then you override two function equals and hashcode, However if you are using ContainsKey method of Treemap on this object then you need to override CompareTo method as well otherwise you will be getting this error Someone using a custom object as a key in hashmap in kotlin should do like following

 data class CustomObjectKey(var key1:String = "" , var 
 key2:String = ""):Comparable<CustomObjectKey?>
 {
override fun compareTo(other: CustomObjectKey?): Int {
    if(other == null)
        return -1
   // suppose you want to do comparison based on key 1 
    return this.key1.compareTo((other)key1)
}

override fun equals(other: Any?): Boolean {
    if(other == null)
        return false
    return this.key1 == (other as CustomObjectKey).key1
}

override fun hashCode(): Int {
    return this.key1.hashCode()
} 
}

You can get the user name using System.Security.Principal.WindowsIdentity.GetCurrent() but there is not way to get current user password!

You can try the following:

$group = array();

foreach ( $array as $value ) {
    $group[$value['id']][] = $value;
}

var_dump($group);

Output:

I've had the same problem. It is just a batch-file, working when manually started, but not working as a scheduled task.

there were drive-letters in the batch-file like this:

put z:\folder\file.ext

seems like you should not use drive-letters, they are bound to the user, who created them - for me this little change made it work again:

put \\server\folder\file.ext

I like using RegEx in this occasion:

str = str.replace(/X/g, '');

where g means global so it will go through your whole string and replace all X with ''; if you want to replace both X and x, you simply say:

str = str.replace(/X|x/g, '');

(see my fiddle here: fiddle)

This worked for me, setting up Googles nameserver because no standard nameserver was specified, followed by restarting networking:

sudo echo "dns-nameservers 8.8.8.8" >> /etc/network/interfaces && sudo ifdown venet0:0 && sudo ifup venet0:0

The whole thing to em is, that the size is relative to the base. So I would say you could keep the font sizes by altering the base.

Example: If you base is 16px, and p is .75em (which is 12px) you would have to raise the base to about 20px. In this case p would then equal about 15px which is the minimum I personally require for mobile phones.

push is an Array method, for json object you may need to define it

this should do it:

library[title] = {"foregrounds" : foregrounds,"backgrounds" : backgrounds};

There are several ways to UPDATE using sqlalchemy

1) user.no_of_logins += 1
   session.commit()

2) session.query().\
       filter(User.username == form.username.data).\
       update({"no_of_logins": (User.no_of_logins +1)})
   session.commit()

3) conn = engine.connect()
   stmt = User.update().\
       values(no_of_logins=(User.no_of_logins + 1)).\
       where(User.username == form.username.data)
   conn.execute(stmt)

4) setattr(user, 'no_of_logins', user.no_of_logins+1)
   session.commit()

breast$class <- as.numeric(as.character(breast$class))

If you have many columns to convert to numeric

indx <- sapply(breast, is.factor)
breast[indx] <- lapply(breast[indx], function(x) as.numeric(as.character(x)))

Another option is to use stringsAsFactors=FALSE while reading the file using read.table or read.csv

Just in case, other options to create/change columns

 breast[,'class'] <- as.numeric(as.character(breast[,'class']))

or

 breast <- transform(breast, class=as.numeric(as.character(breast)))

You want getActivity() inside your class. It's better to use

yourclassname.this.getActivity()

Try this. It's helpful for you.

I ran into this issue constantly while packing my projects into nugets via Visual Studio 2019. After looking for a solution for ages I seem to have solved this by following advice in this article

MSBuild & Typescript

especially part about <TypeScriptCompile /> where I included all my .ts resources with the Include operator and excluded others such as node_modules with the Remove operator. I then deleted the tsconfig.json file in each offending project and the nuget packages were generated and no more errors

I have Python 2.7.5, MySQL 5.6 and CentOS 7.1.1503.

For me it worked with the following command:

# pip install mysql-python

Note pre-requisites here:

Install Python pip:

# rpm -iUvh http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm

# yum -y update
Reboot the machine (if kernel is also updated)

# yum -y install python-pip

Install Python devel packages:

# yum install python-devel

Install MySQL devel packages:

# yum install mysql-devel

Blast from the past but I think I found an easy answer to this. The following worked for me. I think it's the equivalent of selecting the cell hitting F2 and then hitting enter, which makes Excel recognize the text as a date.

Columns("A").Select
Selection.Value = Selection.Value

With the latest version of phpmyadmin 5.0.2+ at least

Check that the actual installation was completed correctly,

Mine had been copied over into a sub folder on a linux machine rather that being at the

/usr/share/phpmyadmin/

typeid(T).name() is implementation defined and doesn't guarantee human readable string.

Reading cppreference.com :

Returns an implementation defined null-terminated character string containing the name of the type. No guarantees are given, in particular, the returned string can be identical for several types and change between invocations of the same program.

...

With compilers such as gcc and clang, the returned string can be piped through c++filt -t to be converted to human-readable form.

But in some cases gcc doesn't return right string. For example on my machine I have gcc whith -std=c++11 and inside template function typeid(T).name() returns "j" for "unsigned int". It's so called mangled name. To get real type name, use abi::__cxa_demangle() function (gcc only):

#include <string>
#include <cstdlib>
#include <cxxabi.h>

template<typename T>
std::string type_name()
{
    int status;
    std::string tname = typeid(T).name();
    char *demangled_name = abi::__cxa_demangle(tname.c_str(), NULL, NULL, &status);
    if(status == 0) {
        tname = demangled_name;
        std::free(demangled_name);
    }   
    return tname;
}

Do you want an 'int' that looks like 20110425171213? In which case you'd be better off ToString with the appropriate format (something like 'yyyyMMddHHmmss') and then casting the string to an integer (or a long, unsigned int as it will be way more than 32 bits).

If you want an actual numeric value (the number of seconds since the year 0) then that's a very different calculation, e.g.

result = second
result += minute * 60
result += hour * 60 * 60
result += day * 60 * 60 * 24 

etc.

But you'd be better off using Ticks.

Either your gradle or build need to know where resources are.

Use ClassLoader#getResource() instead if its URI represents a valid local disk file system path.

URL resource = classLoader.getResource("resource.ext");
File file = new File(resource.toURI());
FileInputStream input = new FileInputStream(file);
// ...

If it doesn't (e.g. JAR), then your best bet is to copy it into a temporary file.

Path temp = Files.createTempFile("resource-", ".ext");
Files.copy(classLoader.getResourceAsStream("resource.ext"), temp, StandardCopyOption.REPLACE_EXISTING);
FileInputStream input = new FileInputStream(temp.toFile());
// ...

That said, I really don't see any benefit of doing so, or it must be required by a poor helper class/method which requires FileInputStream instead of InputStream. If you can, just fix the API to ask for an InputStream instead. If it's a 3rd party one, by all means report it as a bug. I'd in this specific case also put question marks around the remainder of that API.

You can use d6tstack which creates the table for you and is faster than pd.to_sql() because it uses native DB import commands. It supports Postgres as well as MYSQL and MS SQL.

import pandas as pd
df = pd.read_csv('table.csv')
uri_psql = 'postgresql+psycopg2://usr:pwd@localhost/db'
d6tstack.utils.pd_to_psql(df, uri_psql, 'table')

It is also useful for importing multiple CSVs, solving data schema changes and/or preprocess with pandas (eg for dates) before writing to db, see further down in examples notebook

d6tstack.combine_csv.CombinerCSV(glob.glob('*.csv'), 
    apply_after_read=apply_fun).to_psql_combine(uri_psql, 'table')

If other whitespace characters are possible, then you'd want:

testString.split("\\s+");

Mike Bethany's answer above worked to set a default value when a new record was being created and still have the value the user selected show in the edit form. However, I added a model validation and it would not let me submit the form. Here's what worked for me to have a model validation on the field and to show a default value as well as the value the user selected when in edit mode.

  <div class="field">
    <%= f.label :project_id, 'my project id', class: "control-label" %><br>
    <% if @work.new_record? %>
      <%= f.select :project_id, options_for_select([['Yes', true], ['No', false]], true), {}, required: true, class: "form-control" %><br>
    <% else %>
      <%= f.select :project_id, options_for_select([['Yes', true], ['No', false]], @work.project_id), {}, required: true, class: "form-control" %><br>
    <% end %>
  </div>

model validation

  validates :project_id, presence: true

My bad, I had missed one part of the question.

Best, cleanest way is to use a UDF. Explanation within the code.

// create some example data...BY DataFrame
// note, third record has an empty string
case class Stuff(a:String,b:Int)
val d= sc.parallelize(Seq( ("a",1),("b",2),
     ("",3) ,("d",4)).map { x => Stuff(x._1,x._2)  }).toDF

// now the good stuff.
import org.apache.spark.sql.functions.udf
// function that returns 0 is string empty 
val func = udf( (s:String) => if(s.isEmpty) 0 else 1 )
// create new dataframe with added column named "notempty"
val r = d.select( $"a", $"b", func($"a").as("notempty") )

    scala> r.show
+---+---+--------+
|  a|  b|notempty|
+---+---+--------+
|  a|  1|    1111|
|  b|  2|    1111|
|   |  3|       0|
|  d|  4|    1111|

Reference here 2.10.2.1 Troubleshooting Problems Starting the MySQL Server.

1.Find the data directory ,it was configured in my.cnf.

[mysqld]
datadir=/var/lib/mysql

2. Check the err file,it log the error message about why mysql server start failed. the name of err file is related with your hostname.

cd /var/lib/mysql
ll
tail (hostname).err

3.If you find some messages like :

InnoDB: Error: log file ./ib_logfile0 is of different size 0 33554432 bytes
InnoDB: than specified in the .cnf file 0 5242880 bytes!
170513 14:25:22 [ERROR] Plugin 'InnoDB' init function returned error.
170513 14:25:22 [ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed.
170513 14:25:22 [ERROR] Unknown/unsupported storage engine: InnoDB
170513 14:25:22 [ERROR] Aborting

then

delete ib_logfile0 and ib_logfile1

, then,

/etc/init.d/mysqld start

You can use this as well

import numpy as np
x=np.array(['1.1', '2.2', '3.3'])
x=np.asfarray(x,float)

Yes, it's

use Illuminate\Support\Facades\Redirect;

return Redirect::to('http://heera.it');

Check the documentation.

Update: Redirect::away('url') (For external link, Laravel Version 4.19):

public function away($path, $status = 302, $headers = array())
{
    return $this->createRedirect($path, $status, $headers);
}

I had the similar issue. I solved it the following way after a number of attempts to follow the pieces of advice in the forums. I am reposting the solution because it could be helpful for others.

I am running Windows 7 (Apache 2.2 & PHP 5.2.17 & MySQL 5.0.51a), the syntax in the file "httpd.conf" (C:\Program Files (x86)\Apache Software Foundation\Apache2.2\conf\httpd.conf) was sensitive to slashes. You can check if "php.ini" is read from the right directory. Just type in your browser "localhost/index.php". The code of index.php is the following:

<?php echo phpinfo(); ?>

There is the row (not far from the top) called "Loaded Configuration File". So, if there is nothing added, then the problem could be that your "php.ini" is not read, even you uncommented (extension=php_mysql.dll and extension=php_mysqli.dll). So, in order to make it work I did the following step. I needed to change from

PHPIniDir 'c:\PHP\'

to

PHPIniDir 'c:\PHP'

Pay the attention that the last slash disturbed everything!

Now the row "Loaded Configuration File" gets "C:\PHP\php.ini" after refreshing "localhost/index.php" (before I restarted Apache2.2) as well as mysql block is there. MySQL and PHP are working together!

By adding the snippet you extend the Date object.

Date.prototype.getWeek = function() {
    var onejan = new Date(this.getFullYear(),0,1);
    return Math.ceil((((this - onejan) / 86400000) + onejan.getDay()+1)/7);
}

If you want to use this in multiple pages you can add this to a seperate js file which must be loaded first before your other scripts executes. With other scripts I mean the scripts which uses the getWeek() method.

Both will work but xhtml standard requires you to specify the type too:

<script type="text/javascript">..</script> 

<!ELEMENT SCRIPT - - %Script;          -- script statements -->
<!ATTLIST SCRIPT
  charset     %Charset;      #IMPLIED  -- char encoding of linked resource --
  type        %ContentType;  #REQUIRED -- content type of script language --
  src         %URI;          #IMPLIED  -- URI for an external script --
  defer       (defer)        #IMPLIED  -- UA may defer execution of script --
  >

type = content-type [CI] This attribute specifies the scripting language of the element's contents and overrides the default scripting language. The scripting language is specified as a content type (e.g., "text/javascript"). Authors must supply a value for this attribute. There is no default value for this attribute.

Notices the emphasis above.

http://www.w3.org/TR/html4/interact/scripts.html

Note: As of HTML5 (far away), the type attribute is not required and is default.

Does anyone know how to get sed to print the position of the illegal byte sequence? Or does anyone know what the illegal byte sequence is?

I got part of the way to answering the above just by using tr.

I have a .csv file that is a credit card statement and I am trying to import it into Gnucash. I am based in Switzerland so I have to deal with words like Zürich. Suspecting Gnucash does not like " " in numeric fields, I decide to simply replace all

; ;

with

;;

Here goes:

$ head -3 Auswertungen.csv | tail -1 | sed -e 's/; ;/;;/g'
sed: RE error: illegal byte sequence

I used od to shed some light: Note the 374 halfway down this od -c output

$ head -3 Auswertungen.csv | tail -1 | od -c
0000000    1   6   8   7       9   6   1   9       7   1   2   2   ;   5

0000060    4   .   0   2   .   2   0   1   9   ;   9   5   5   2       -
0000100        M   i   t   a   r   b   e   i   t   e   r   r   e   s   t
0000120                Z 374   r   i   c   h                            
0000140    C   H   E   ;   R   e   s   t   a   u   r   a   n   t   s   ,
0000160        B   a   r   s   ;   6   .   2   0   ;   C   H   F   ;    
0000200    ;   C   H   F   ;   6   .   2   0   ;       ;   1   5   .   0
0000220    2   .   2   0   1   9  \n                                    
0000227

Then I thought I might try to persuade tr to substitute 374 for whatever the correct byte code is. So first I tried something simple, which didn't work, but had the side effect of showing me where the troublesome byte was:

$ head -3 Auswertungen.csv | tail -1 | tr . .  ; echo
tr: Illegal byte sequence
1687 9619 7122;5468 87XX XXXX 2660;MY NAME ISX;14.02.2019;9552 - Mitarbeiterrest   Z

You can see tr bails at the 374 character.

Using perl seems to avoid this problem

$ head -3 Auswertungen.csv | tail -1 | perl -pne 's/; ;/;;/g'
1687 9619 7122;5468 87XX XXXX 2660;ADAM NEALIS;14.02.2019;9552 - Mitarbeiterrest   Z?rich       CHE;Restaurants, Bars;6.20;CHF;;CHF;6.20;;15.02.2019

The match attribute indicates on which parts the template transformation is going to be applied. In that particular case the "/" means the root of the xml document. The value you have to provide into the match attribute should be XPath expression. XPath is the language you have to use to refer specific parts of the target xml file.

To gain a meaningful understanding of what else you can put into match attribute you need to understand what xpath is and how to use it. I suggest yo look at links I've provided for youat the bottom of the answer.

Could I write "table" or any other html tag instead of "/" ?

Yes you can. But this depends what exactly you are trying to do. if your target xml file contains HMTL elements and you are triyng to apply this xsl:template on them it makes sense to use table, div or anithing else.

Here a few links:

• XSL templates
• XPath
• A good book about XML - Beginning XML

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); 

select 
    status_id, 
    status, 
    null as path, 
    null as Description 
from 
    zmw_t_status

union
select 
    null, 
    null, 
    path as cid, 
    Description from zmw_t_path;

Best is to just Apply margin-top: 2px on the input element.

Bootstrap adds a margin-top: 4px to input element causing radio button to move down than the content.

Not completely sure I understand the question, but do you mean something like this?

$('#something').click(function() { 
    document.location = 'http://somewhere.com/';
} );

Tag ids must be unique. You are updating the span with ID 'ItemCostSpan' of which there are two. Give the span a class and get it using find.

    $("legend").each(function() {
        var SoftwareItem = $(this).text();
        itemCost = GetItemCost(SoftwareItem);
        $("input:checked").each(function() {               
            var Component = $(this).next("label").text();
            itemCost += GetItemCost(Component);
        });            
        $(this).find(".ItemCostSpan").text("Item Cost = $ " + itemCost);
    });

You can use the php serialize function to store array in MySQL.

<?php

$array = array("Name"=>"Shubham","Age"=>"17","website"=>"http://mycodingtricks.com");

$string_array = serialize($array);

echo $string_array;

?>

It’s output will be :

a:3{s:4:"Name";s:7:"Shubham";s:3:"Age";s:2:"17";s:7:"website";s:25:"http://mycodingtricks.com";}

And then you can use the php unserialize function to decode the data.

I think you should visit this page on storing array in mysql.

I'm still experiencing this behavior with jQuery 1.7.2. A simple workaround is to defer the execution of the click handler with setTimeout and let the browser do its magic in the meantime:

$("#myCheckbox").click( function() {
    var that = this;
    setTimeout(function(){
        alert($(that).is(":checked"));
    });
});

A short traverse could be given too using the sub-expression operator $( ), which returns the result of one or more statements.

$hash = @{ a = 1; b = 2; c = 3}

forEach($y in $hash.Keys){
    Write-Host "$y -> $($hash[$y])"
}

Result:

a -> 1
b -> 2
c -> 3

I got this error when I ran react-native run-ios --scheme="customscheme" and the name of customscheme was misspelled.

You dont need both jTDS and JDBC in your classpath. Any one is required. Here you need only sqljdbc.jar.

Also, I would suggest to place sqljdbc.jar at physical location to /WEB-INF/lib directory of your project rather than adding it in the Classpath via IDE. Then Tomcat takes care the rest. And also try restarting Tomcat.

You can download Jar from : www.java2s.com/Code/JarDownload/sqlserverjdbc/sqlserverjdbc.jar.zip

EDIT:

As you are supplying Username and Password when connecting,

You need only jdbc:sqlserver://localhost:1433;databaseName=test, Skip integratedSecurity attribute.

The functions in stdlib.h and stdio.h have implementations in libc.so (or libc.a for static linking), which is linked into your executable by default (as if -lc were specified). GCC can be instructed to avoid this automatic link with the -nostdlib or -nodefaultlibs options.

The math functions in math.h have implementations in libm.so (or libm.a for static linking), and libm is not linked in by default. There are historical reasons for this libm/libc split, none of them very convincing.

Interestingly, the C++ runtime libstdc++ requires libm, so if you compile a C++ program with GCC (g++), you will automatically get libm linked in.

If I don't know the size up front, I use an arraylist instead of an array.

$al = New-Object System.Collections.ArrayList
for($i=0; $i -lt 5; $i++)
{
    $al.Add($i)
}

Just set the width to 100vw like this:

<div id="container" style="width: 100vw">
 <div id="help_panel" style="width: 100%; margin: 0 auto;">
  Content goes here.
 </div> 
</div>

The UUID is used for uniquely identifying information. It identifies a particular service provided by a Bluetooth device. The standard defines a basic BASE_UUID: 00000000-0000-1000-8000-00805F9B34FB.

Devices such as healthcare sensors can provide a service, substituting the first eight digits with a predefined code. For example, a device that offers an RFCOMM connection uses the short code: 0x0003

So, an Android phone can connect to a device and then use the Service Discovery Protocol (SDP) to find out what services it provides (UUID).

In many cases, you don't need to use these fixed UUIDs. In the case your are creating a chat application, for example, one Android phone interacts with another Android phone that uses the same application and hence the same UUID.

So, you can set an arbitrary UUID for your application using, for example, one of the many random UUID generators on the web (for example).

I do not see why clearing data would be better than a script to drop and re-create each table.

That or keep a back up of your empty DB and restore it over old one

If the project came with a Visual Studio project file, then that should already be configured to find the headers for you. If not, you'll have to add the include file directory to the project settings by right-clicking the project and selecting Properties, clicking on "C/C++", and adding the directory containing the include files to the "Additional Include Directories" edit box.

If you have missed to add unique to DB column, just add this validation in model to check if the field is unique:

class Person < ActiveRecord::Base
  validates_uniqueness_of :user_name
end

refer here Above is for testing purpose only, please add index by changing DB column as suggested by @Nate

please refer this with index for more information

If it's a Maven project then Netbeans is running your application using the exec-maven-plugin so you'll need to append your options onto the existing exec.args property found in the Run Maven dialog. This dialog can be accessed from the the Output window by pressing the yellow double arrow icon.

if you what to obtain "ONE" by giving in 100 then

initialize hash map by

hashmap = new HashMap<Object,String>();

haspmap.put(100,"one");

and retrieve value by hashMap.get(100)

hope that helps.

Engine must be before select:

CREATE TEMPORARY TABLE temp1 ENGINE=MEMORY 
as (select * from table1)

UPDATE: I have created a video on sending multipart/form-data requests to explain this better.

Actually, Postman can do this. Here is a screenshot

Newer version : Screenshot captured from postman chrome extension

Another version

Older version

Make sure you check the comment from @maxkoryukov

Be careful with explicit Content-Type header. Better - do not set it's value, the Postman is smart enough to fill this header for you. BUT, if you want to set the Content-Type: multipart/form-data - do not forget about boundary field.

The sort-stream may also be used to ensure specific order of files with gulp.src. Sample code that puts the backbone.js always as the last file to process:

var gulp = require('gulp');
var sort = require('sort-stream');
gulp.task('scripts', function() {
gulp.src(['./source/js/*.js', './source/js/**/*.js'])
  .pipe(sort(function(a, b){
    aScore = a.path.match(/backbone.js$/) ? 1 : 0;
    bScore = b.path.match(/backbone.js$/) ? 1 : 0;
    return aScore - bScore;
  }))
  .pipe(concat('script.js'))
  .pipe(stripDebug())
  .pipe(uglify())
  .pipe(gulp.dest('./build/js/'));
});

If you need that in js code. You can use injected method of angula-filter lib. Like this.

function controller($scope, $http, groupByFilter) {     

   var groupedData = groupByFilter(originalArray, 'groupPropName');

}

https://github.com/a8m/angular-filter/wiki/Common-Questions#inject-filters

This worked for me, it works in firefox, ie and chrome.

    var content = "This is a test Message";

    var contentHtml = [
        '<div><b>',
        'TestReport',
        '<button style="float:right; margin-right:10px;"',
        'id="printButton" onclick="printDocument()">Print</button></div>',
        content
    ].join('');

    var printWindow = window.open();

    printWindow.document.write('<!DOCTYPE HTML><html><head<title>Reports</title>',
        '<script>function printDocument() {',
        'window.focus();',
        'window.print();',
        'window.close();',
        '}',
        '</script>');

    printWindow.document.write("stylesheet link here");

    printWindow.document.write('</head><body>');
    printWindow.document.write(contentHtml);
    printWindow.document.write('</body>');
    printWindow.document.write('</html>');
    printWindow.document.close();

You can use any of these two:

return redirect()->back()->withInput(Input::all())->with('message', 'Some message');

Or,

return redirect('url_goes_here')->withInput(Input::all())->with('message', 'Some message');

Pidfile contains pid of a process. It is a convention allowing long running processes to be more self-aware. Server process can inspect it to stop itself, or have heuristic that its other instance is already running. Pidfiles can also be used to conventiently kill risk manually, e.g. pkill -F <some.pid>

If you have pandas installed, you can convert the ordered dict to a pandas Series. This will allow random access to the dictionary elements.

>>> import collections
>>> import pandas as pd
>>> d = collections.OrderedDict()
>>> d['foo'] = 'python'
>>> d['bar'] = 'spam'

>>> s = pd.Series(d)

>>> s['bar']
spam
>>> s.iloc[1]
spam
>>> s.index[1]
bar

A very, very good resource for these kinds of algorithms is Simmetrics: http://sourceforge.net/projects/simmetrics/

Unfortunately the awesome website containing a lot of the documentation is gone :( In case it comes back up again, its previous address was this: http://www.dcs.shef.ac.uk/~sam/simmetrics.html

Voila (courtesy of "Wayback Machine"): http://web.archive.org/web/20081230184321/http://www.dcs.shef.ac.uk/~sam/simmetrics.html

You can study the code source, there are dozens of algorithms for these kinds of comparisons, each with a different trade-off. The implementations are in Java.

The typical form for dynamically allocating an NxM array of type T is

T **a = malloc(sizeof *a * N);
if (a)
{
  for (i = 0; i < N; i++)
  {
    a[i] = malloc(sizeof *a[i] * M);
  }
}

If each element of the array has a different length, then replace M with the appropriate length for that element; for example

T **a = malloc(sizeof *a * N);
if (a)
{
  for (i = 0; i < N; i++)
  {
    a[i] = malloc(sizeof *a[i] * length_for_this_element);
  }
}

declare @result as smallint
declare @delete as smallint = 2
declare @insert as smallint = 4
declare @update as smallint = 6
SELECT @result = POWER(2*(SELECT count(*) from deleted),1) + POWER(2*(SELECT 
     count(*) from inserted),2)

if (@result & @update = @update) 
BEGIN
  print 'update'
  SET @result=0
END
if (@result & @delete = @delete)
  print 'delete'
if (@result & @insert = @insert)
  print 'insert'

Sometimes we want to catch a SIGSEGV to find out if a pointer is valid, that is, if it references a valid memory address. (Or even check if some arbitrary value may be a pointer.)

One option is to check it with isValidPtr() (worked on Android):

int isValidPtr(const void*p, int len) {
    if (!p) {
    return 0;
    }
    int ret = 1;
    int nullfd = open("/dev/random", O_WRONLY);
    if (write(nullfd, p, len) < 0) {
    ret = 0;
    /* Not OK */
    }
    close(nullfd);
    return ret;
}
int isValidOrNullPtr(const void*p, int len) {
    return !p||isValidPtr(p, len);
}

Another option is to read the memory protection attributes, which is a bit more tricky (worked on Android):

re_mprot.c:

#include <errno.h>
#include <malloc.h>
//#define PAGE_SIZE 4096
#include "dlog.h"
#include "stdlib.h"
#include "re_mprot.h"

struct buffer {
    int pos;
    int size;
    char* mem;
};

char* _buf_reset(struct buffer*b) {
    b->mem[b->pos] = 0;
    b->pos = 0;
    return b->mem;
}

struct buffer* _new_buffer(int length) {
    struct buffer* res = malloc(sizeof(struct buffer)+length+4);

egrep -ir --include=*.{php,html,js} "(document.cookie|setcookie)" .

The r flag means to search recursively (search subdirectories). The i flag means case insensitive.

If you just want file names add the l (lowercase L) flag:

egrep -lir --include=*.{php,html,js} "(document.cookie|setcookie)" .

Take a look in .git/config and make the changes you need.

Alternatively you could use

git remote rm [name of the url you sets on adding]

and

git remote add [name] [URL]

Or just

git remote set-url [URL]

Before you do anything wrong, double check with

git help remote

Here is an example to play with Inline SVG for a list bullet (2020 Browsers)

For the new Criteria since version Hibernate 5.2:

CriteriaBuilder criteriaBuilder = getSession().getCriteriaBuilder();
CriteriaQuery<SomeClass> criteriaQuery = criteriaBuilder.createQuery(SomeClass.class);

Root<SomeClass> root = criteriaQuery.from(SomeClass.class);

Path<Object> expressionA = root.get("A");
Path<Object> expressionB = root.get("B");

Predicate predicateAEqualX = criteriaBuilder.equal(expressionA, "X");
Predicate predicateBInXY = expressionB.in("X",Y);
Predicate predicateLeft = criteriaBuilder.and(predicateAEqualX, predicateBInXY);

Predicate predicateAEqualY = criteriaBuilder.equal(expressionA, Y);
Predicate predicateBEqualZ = criteriaBuilder.equal(expressionB, "Z");
Predicate predicateRight = criteriaBuilder.and(predicateAEqualY, predicateBEqualZ);

Predicate predicateResult = criteriaBuilder.or(predicateLeft, predicateRight);

criteriaQuery
        .select(root)

List<SomeClass> list = getSession()
        .createQuery(criteriaQuery)

TEXT is a data-type for text based input. On the other hand, you have BLOB and CLOB which are more suitable for data storage (images, etc) due to their larger capacity limits (4GB for example).

As for the difference between BLOB and CLOB, I believe CLOB has character encoding associated with it, which implies it can be suited well for very large amounts of text.

BLOB and CLOB data can take a long time to retrieve, relative to how quick data from a TEXT field can be retrieved. So, use only what you need.

Font Squirrel has a wonderful web font generator.

I think you should find what you need here to generate OTF fonts and the needed CSS to use them. It will even support older IE versions.

You can find an example below. Basically you attach a function to window's scroll event and trace scrollTop property and if it's higher than desired threshold you apply position: fixed and some other css properties.

jQuery(function($) {_x000D_
  $(window).scroll(function fix_element() {_x000D_
    $('#target').css(_x000D_
      $(window).scrollTop() > 100_x000D_
        ? { 'position': 'fixed', 'top': '10px' }_x000D_
        : { 'position': 'relative', 'top': 'auto' }_x000D_
    );_x000D_
    return fix_element;_x000D_
  }());_x000D_
});

body {_x000D_
  height: 2000px;_x000D_
  padding-top: 100px;_x000D_
}_x000D_
code {_x000D_
  padding: 5px;_x000D_
  background: #efefef;_x000D_
}_x000D_
#target {_x000D_
  color: #c00;_x000D_
  font: 15px arial;_x000D_
  padding: 10px;_x000D_
  margin: 10px;_x000D_
  border: 1px solid #c00;_x000D_
  width: 200px;_x000D_
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<div id="target">This <code>div</code> is going to be fixed</div>

Only using css techniques this does not seem possible to me. But you could use jqueryui draggable:

$('#drag_me').draggable();

In Bash, test and [ are shell builtins.

The double bracket, which is a shell keyword, enables additional functionality. For example, you can use && and || instead of -a and -o and there's a regular expression matching operator =~.

Also, in a simple test, double square brackets seem to evaluate quite a lot quicker than single ones.

$ time for ((i=0; i<10000000; i++)); do [[ "$i" = 1000 ]]; done

real    0m24.548s
user    0m24.337s
sys 0m0.036s
$ time for ((i=0; i<10000000; i++)); do [ "$i" = 1000 ]; done

real    0m33.478s
user    0m33.478s
sys 0m0.000s

The braces, in addition to delimiting a variable name are used for parameter expansion so you can do things like:

• Truncate the contents of a variable

  $ var="abcde"; echo ${var%d*}
  abc
  

• Make substitutions similar to sed

  $ var="abcde"; echo ${var/de/12}
  abc12
  

• Use a default value

  $ default="hello"; unset var; echo ${var:-$default}
  hello
  

• and several more

Also, brace expansions create lists of strings which are typically iterated over in loops:

$ echo f{oo,ee,a}d
food feed fad

$ mv error.log{,.OLD}
(error.log is renamed to error.log.OLD because the brace expression
expands to "mv error.log error.log.OLD")

$ for num in {000..2}; do echo "$num"; done
000
001
002

$ echo {00..8..2}
00 02 04 06 08

$ echo {D..T..4}
D H L P T

Note that the leading zero and increment features weren't available before Bash 4.

Thanks to gboffi for reminding me about brace expansions.

Double parentheses are used for arithmetic operations:

((a++))

((meaning = 42))

for ((i=0; i<10; i++))

echo $((a + b + (14 * c)))

and they enable you to omit the dollar signs on integer and array variables and include spaces around operators for readability.

Single brackets are also used for array indices:

array[4]="hello"

element=${array[index]}

Curly brace are required for (most/all?) array references on the right hand side.

ephemient's comment reminded me that parentheses are also used for subshells. And that they are used to create arrays.

array=(1 2 3)
echo ${array[1]}
2

For new line characters

UPDATE table_name SET field_name = TRIM(TRAILING '\n' FROM field_name);
UPDATE table_name SET field_name = TRIM(TRAILING '\r' FROM field_name);
UPDATE table_name SET field_name = TRIM(TRAILING '\r\n' FROM field_name);

For all white space characters

UPDATE table_name SET field_name = TRIM(field_name);
UPDATE table_name SET field_name = TRIM(TRAILING '\n' FROM field_name);
UPDATE table_name SET field_name = TRIM(TRAILING '\r' FROM field_name);
UPDATE table_name SET field_name = TRIM(TRAILING '\r\n' FROM field_name);
UPDATE table_name SET field_name = TRIM(TRAILING '\t' FROM field_name);

As @ashishduh mentioned above, using android:autoLink="phone is also a good solution. But this option comes with one drawback, it doesn't work with all phone number lengths. For instance, a phone number of 11 numbers won't work with this option. The solution is to prefix your phone numbers with the country code.

Example:

08034448845 won't work

but +2348034448845 will

Map<String, String> x;
Map<String, Integer> y =
    x.entrySet().stream()
        .collect(Collectors.toMap(
            e -> e.getKey(),
            e -> Integer.parseInt(e.getValue())
        ));

It's not quite as nice as the list code. You can't construct new Map.Entrys in a map() call so the work is mixed into the collect() call.

In case someone is still looking for the answer, this worked for me:

=COUNTIF(A2:A51, "*" & B1 & "*")

B1 containing the iPad string.

No, if you are debugging an app without other users use the Build > Build APK(s) menu in Android Studio or execute it in your device/emulator them the debug release apk will install automatically. If you are debugging an app with others use Build > Generate Signed APK... menu. If you want to publish the beta version use the Google Play Store. Your APK(s) will be in app\build\outputs\apk\debug and app\release folders.

I was just playing a bit to try to make a dict comprehension with reduce, and come up with this one liner hack:

In [1]: from functools import reduce
In [2]: reduce(lambda d, i: (i[0] < 7 and d.__setitem__(*i[::-1]), d)[-1], [{}, *{1:2, 3:4, 5:6, 7:8}.items()])                                                                                                                                                                 
Out[3]: {2: 1, 4: 3, 6: 5}

I was just trying to do the same as what was done in this Javascript dict comprehension: https://stackoverflow.com/a/11068265

There's, however, slight difference among all these options which

I found out that

If you do

    string URL = Server.MapPath("~");

or

    string URL = Server.MapPath("/");

or

    string URL = HttpRuntime.AppDomainAppPath;

your URL will display resources in your link like this:

    "file:///d:/InetPUB/HOME/Index/bin/Resources/HandlerDoc.htm"

But if you want your URL to show only virtual path not the resources location, you should do

    string URL = HttpRuntime.AppDomainAppVirtualPath; 

then, your URL is displaying a virtual path to your resources as below

    "http://HOME/Index/bin/Resources/HandlerDoc.htm"        

if not exists (select * from sysobjects where name='cars' and xtype='U')
    create table cars (
        Name varchar(64) not null
    )
go

The above will create a table called cars if the table does not already exist.

The > is a child selector. So if your HTML looks like this:

<h1 class="hc-reform">
    title
    <p>stuff here</p>
</h1>

... then that's your ticket.

But if your HTML looks like this:

<h1 class="hc-reform">
    title
</h1>
<p>stuff here</p>

Then you want the adjacent selector:

h1.hc-reform + p{
     clear:both;
}
