The IHttpContextAccessor method does work if you wish to go this route.

TLDR;

• Inject the IHttpContextAccessor

• Rewind -- HttpContextAccessor.HttpContext.Request.Body.Seek(0, System.IO.SeekOrigin.Begin);

• Read -- System.IO.StreamReader sr = new System.IO.StreamReader(HttpContextAccessor.HttpContext.Request.Body); JObject asObj = JObject.Parse(sr.ReadToEnd());

More -- An attempt at a concise, non-compiling, example of the items you'll need to ensure are in place in order to get at a useable IHttpContextAccessor. Answers have pointed out correctly that you'll need to seek back to the start when you try to read the request body. The CanSeek, Position properties on the request body stream helpful for verifying this.

.NET Core DI Docs

// First -- Make the accessor DI available
//
// Add an IHttpContextAccessor to your ConfigureServices method, found by default
// in your Startup.cs file:
// Extraneous junk removed for some brevity:
public void ConfigureServices(IServiceCollection services)
{
    // Typical items found in ConfigureServices:
    services.AddMvc(config => { config.Filters.Add(typeof(ExceptionFilterAttribute)); });
    // ...

    // Add or ensure that an IHttpContextAccessor is available within your Dependency Injection container
    services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();
}

// Second -- Inject the accessor
//
// Elsewhere in the constructor of a class in which you want
// to access the incoming Http request, typically 
// in a controller class of yours:
public class MyResourceController : Controller
{
    public ILogger<PricesController> Logger { get; }
    public IHttpContextAccessor HttpContextAccessor { get; }

    public CommandController(
        ILogger<CommandController> logger,
        IHttpContextAccessor httpContextAccessor)
    {
        Logger = logger;
        HttpContextAccessor = httpContextAccessor;
    }

    // ...

    // Lastly -- a typical use 
    [Route("command/resource-a/{id}")]
    [HttpPut]
    public ObjectResult PutUpdate([FromRoute] string id, [FromBody] ModelObject requestModel)
    {
        if (HttpContextAccessor.HttpContext.Request.Body.CanSeek)
        {
            HttpContextAccessor.HttpContext.Request.Body.Seek(0, System.IO.SeekOrigin.Begin);
            System.IO.StreamReader sr = new System.IO.StreamReader(HttpContextAccessor.HttpContext.Request.Body);
            JObject asObj = JObject.Parse(sr.ReadToEnd());

            var keyVal = asObj.ContainsKey("key-a");
        }
    }
}    

1) When the user logs out (Forms signout in Action) I want to redirect to a login page.

public ActionResult Logout() {
    //log out the user
    return RedirectToAction("Login");
}

2) In a Controller or base Controller event eg Initialze, I want to redirect to another page (AbsoluteRootUrl + Controller + Action)

Why would you want to redirect from a controller init?

the routing engine automatically handles requests that come in, if you mean you want to redirect from the index action on a controller simply do:

public ActionResult Index() {
    return RedirectToAction("whateverAction", "whateverController");
}

After writing commit message, just press Esc Button and then write :wq or :wq! and then Enter to close the unix file.

left = None

left is None #evaluates to True

Since the inputs are empty and therefore invalid when instantiated, Angular correctly adds the ng-invalid class.

A CSS rule you might try:

input.ng-dirty.ng-invalid {
  color: red
}

Which basically states when the field has had something entered into it at some point since the page loaded and wasn't reset to pristine by $scope.formName.setPristine(true) and something wasn't yet entered and it's invalid then the text turns red.

Other useful classes for Angular forms (see input for future reference )

ng-valid-maxlength - when ng-maxlength passes
ng-valid-minlength - when ng-minlength passes
ng-valid-pattern - when ng-pattern passes
ng-dirty - when the form has had something entered since the form loaded
ng-pristine - when the form input has had nothing inserted since loaded (or it was reset via setPristine(true) on the form)
ng-invalid - when any validation fails (required, minlength, custom ones, etc)

Likewise there is also ng-invalid-<name> for all these patterns and any custom ones created.

DSO here means Dynamic Shared Object; since the error message says it's missing from the command line, I guess you have to add it to the command line.

That is, try adding -lpthread to your command line.

First: monkey patching is an evil hack (in my opinion).

It is often used to replace a method on the module or class level with a custom implementation.

The most common usecase is adding a workaround for a bug in a module or class when you can't replace the original code. In this case you replace the "wrong" code through monkey patching with an implementation inside your own module/package.

I faced the same problem. I had a zip archive which java.util.zip.ZipFile was not able to handle but WinRar unpacked it just fine. I found article on SDN about compressing and decompressing options in Java. I slightly modified one of example codes to produce method which was finally capable of handling the archive. Trick is in using ZipInputStream instead of ZipFile and in sequential reading of zip archive. This method is also capable of handling empty zip archive. I believe you can adjust the method to suit your needs as all zip classes have equivalent subclasses for .jar archives.

public void unzipFileIntoDirectory(File archive, File destinationDir) 
    throws Exception {
    final int BUFFER_SIZE = 1024;
    BufferedOutputStream dest = null;
    FileInputStream fis = new FileInputStream(archive);
    ZipInputStream zis = new ZipInputStream(new BufferedInputStream(fis));
    ZipEntry entry;
    File destFile;
    while ((entry = zis.getNextEntry()) != null) {
        destFile = FilesystemUtils.combineFileNames(destinationDir, entry.getName());
        if (entry.isDirectory()) {
            destFile.mkdirs();
            continue;
        } else {
            int count;
            byte data[] = new byte[BUFFER_SIZE];
            destFile.getParentFile().mkdirs();
            FileOutputStream fos = new FileOutputStream(destFile);
            dest = new BufferedOutputStream(fos, BUFFER_SIZE);
            while ((count = zis.read(data, 0, BUFFER_SIZE)) != -1) {
                dest.write(data, 0, count);
            }
            dest.flush();
            dest.close();
            fos.close();
        }
    }
    zis.close();
    fis.close();
}

I got this error too but for a different reason. It turns out I had made a typo when I tried to specify the version number as a variable:

dependencies {
    // ...
    implementation "com.google.android.gms:play-services-location:{$playServices}"
    // ...
}

I had defined the variable playServices in gradle.properties in my project's root directory:

playServices=15.0.1

The typo was {$playServices} which should have said ${playServices} like this:

dependencies {
    // ...
    implementation "com.google.android.gms:play-services-location:${playServices}"
    // ...
}

That fixed the problem for me.

If you create a new (not yet implemented) function in NetBeans, then it generates a method body with the following statement:

throw new java.lang.UnsupportedOperationException("Not supported yet.");

Therefore, I recommend to use the UnsupportedOperationException.

How about this: 

select * from fab_scheduler where custid = 1334666058 and eventdate = eventdate + INTERVAL 1 DAY

Save this xml and add as a background for the linear layout....

<shape xmlns:android="http://schemas.android.com/apk/res/android"> 
    <stroke android:width="4dp" android:color="#FF00FF00" /> 
    <solid android:color="#ffffff" /> 
    <padding android:left="7dp" android:top="7dp" 
            android:right="7dp" android:bottom="0dp" /> 
    <corners android:radius="4dp" /> 
</shape>

Hope this helps! :)

If you do not want to use other library, here is a simple function to convert InputStream to OutputStream.

public static void copyStream(InputStream in, OutputStream out) throws IOException {
    byte[] buffer = new byte[1024];
    int read;
    while ((read = in.read(buffer)) != -1) {
        out.write(buffer, 0, read);
    }
}

Now you can easily write an Inputstream into file by using FileOutputStream-

FileOutputStream out = new FileOutputStream(outFile);
copyStream (inputStream, out);
out.close();

make is a GNU command so the only way you can get it on Windows is installing a Windows version like the one provided by GNUWin32. Anyway, there are several options for getting that:

1. Using MinGW, be sure you have C:\MinGW\bin\mingw32-make.exe. Otherwise you're missing the mingw32-make additional utilities. Look for the link at MinGW's HowTo page to get it installed. Once you've got it, you have two choices:

• 1.1 Copy the MinGW make executable to make.exe:

  copy c:\MinGW\bin\mingw32-make.exe c:\MinGW\bin\make.exe
  

• 1.2 Create a link to the actual executable, in your PATH. In this case, if you update MinGW, the link is not deleted:

  mklink c:\bin\make.exe C:\MinGW\bin\mingw32-make.exe
  

2. Other option is using Chocolatey. First you need to install this package manager. Once installed you simlpy need to install make:

   choco install make
   

3. Last option is installing a Windows Subsystem for Linux (WSL), so you'll have a Linux distribution of your choice embedded in Windows 10 where you'll be able to install make, gccand all the tools you need to build C programs.

DAO is an abstraction of data persistence.
Repository is an abstraction of a collection of objects.

DAO would be considered closer to the database, often table-centric.
Repository would be considered closer to the Domain, dealing only in Aggregate Roots.

Repository could be implemented using DAO's, but you wouldn't do the opposite.

Also, a Repository is generally a narrower interface. It should be simply a collection of objects, with a Get(id), Find(ISpecification), Add(Entity).

A method like Update is appropriate on a DAO, but not a Repository - when using a Repository, changes to entities would usually be tracked by separate UnitOfWork.

It does seem common to see implementations called a Repository that is really more of a DAO, and hence I think there is some confusion about the difference between them.

this answer can be confusing

do read the comments attached to this post and make sure this is what you are after

'svn delete' works against repository content, not against the repository itself. for doing repository maintenance (like completely deleting one) you should use svnadmin. However, there's a reason why svnadmin doesn't have a 'delete' subcommand. You can just

rm -rf $REPOS_PATH

on the svn server,

where $REPOS_PATH is the path you used to create your repository with

svnadmin create $REPOS_PATH

You can use the run command and specify your services to run. Be careful, the run command does not expose ports to the host. You should use the flag --service-ports to do that if needed.

docker-compose run --service-ports client server database

This is a good description of its uses and shortcomings. You essentially use it whenever you need to do fast low-level I/O. If you were going to implement a TCP/IP protocol or if you were writing a database (DBMS) this class would come in handy.

If you install MySQL via homebrew on MacOS, you might need to delete your old data directory /usr/local/var/mysql. Otherwise, it will fail during the initialization process with the following error:

Different types to check the values exists

d = {"key1":"value1", "key2":"value2"}
"value10" in d.values() 
>> False

What if list of values

test = {'key1': ['value4', 'value5', 'value6'], 'key2': ['value9'], 'key3': ['value6']}
"value4" in [x for v in test.values() for x in v]
>>True

What if list of values with string values

test = {'key1': ['value4', 'value5', 'value6'], 'key2': ['value9'], 'key3': ['value6'], 'key5':'value10'}
values = test.values()
"value10" in [x for v in test.values() for x in v] or 'value10' in values
>>True

MySQL use HAVING statement for this tasks.

Your query would look like this:

SELECT g.group_id, COUNT(m.member_id) AS members
FROM groups AS g
LEFT JOIN group_members AS m USING(group_id)
GROUP BY g.group_id
HAVING members > 4

example when references have different names

SELECT g.id, COUNT(m.member_id) AS members
FROM groups AS g
LEFT JOIN group_members AS m ON g.id = m.group_id
GROUP BY g.id
HAVING members > 4

Also, make sure that you set indexes inside your database schema for keys you are using in JOINS as it can affect your site performance.

(parseFloat('2.3') + parseFloat('2.4')).toFixed(1);

its going to give you solution i suppose

i had the same issue, my solution:

Before:

CREATE TABLE EMPRES
( NoFilm smallint NOT NULL

  PRIMARY KEY (NoFilm)

  FOREIGN KEY (NoFilm) REFERENCES cassettes

);

Solution:

CREATE TABLE EMPRES
(NoFilm smallint NOT NULL REFERENCES cassettes,

 PRIMARY KEY (NoFilm)

);

I hope it's help ;)

I had faced the same problem a few days ago.

I found the solution.

1. control panel
2. open administrative tool
3. services
4. find mysql80
5. start the service

also, check the username and password.

ES6 way, without mutating original data.

var projects = [
{
    value: "jquery",
    label: "jQuery",
    desc: "the write less, do more, JavaScript library",
    icon: "jquery_32x32.png"
},
{
    value: "jquery-ui",
    label: "jQuery UI",
    desc: "the official user interface library for jQuery",
    icon: "jqueryui_32x32.png"
}];

//find the index of object from array that you want to update
const objIndex = projects.findIndex(obj => obj.value === 'jquery-ui');

// make new object of updated object.   
const updatedObj = { ...projects[objIndex], desc: 'updated desc value'};

// make final new array of objects by combining updated object.
const updatedProjects = [
  ...projects.slice(0, objIndex),
  updatedObj,
  ...projects.slice(objIndex + 1),
];

console.log("original data=", projects);
console.log("updated data=", updatedProjects);

Use the optional font argument to turtle.write(), from the docs:

turtle.write(arg, move=False, align="left", font=("Arial", 8, "normal"))
 Parameters:

• arg – object to be written to the TurtleScreen
• move – True/False
• align – one of the strings “left”, “center” or right”
• font – a triple (fontname, fontsize, fonttype)

So you could do something like turtle.write("messi fan", font=("Arial", 16, "normal")) to change the font size to 16 (default is 8).

For a cell to self-reference itself:

INDIRECT(ADDRESS(ROW(), COLUMN()))

For a cell to self-reference its column:

INDIRECT(ADDRESS(1,COLUMN()) & ":" & ADDRESS(65536, COLUMN()))

For a cell to self-reference its row:

INDIRECT(ADDRESS(ROW(),1) & ":" & ADDRESS(ROW(),256))
or
INDIRECT("A" & ROW() & ":IV" & ROW())

The numbers are for 2003 and earlier, use column:XFD and row:1048576 for 2007+.

Note: The INDIRECT function is volatile and should only be used when needed.

In laymen's terms, if you use the @Transient annotation on an attribute of an entity: this attribute will be singled out and will not be saved to the database. The rest of the attribute of the object within the entity will still be saved.

Im saving the Object to the database using the jpa repository built in save method as so:

userRoleJoinRepository.save(user2);

try to get out grafics with x11() or win.graph() and solve this trouble.

I solved it moving the file spring-context.xml in a src folder. ApplicationContext context = new ClassPathXmlApplicationContext("spring-context.xml");

a <div> can be focused if it has a tabindex attribute. (the value can be set to -1)

For example:

$("#focus_point").attr("tabindex",-1).focus();

In addition, consider setting outline: none !important; so it displayed without a focus rectangle.

var element = $("#focus_point");
element.css('outline', 'none !important')
       .attr("tabindex", -1)
       .focus();

You can see the structure of the object returned by summary() by calling str(summary(fit)). Each piece can be accessed using $. The p-value for the F statistic is more easily had from the object returned by anova.

Concisely, you can do this:

rSquared <- summary(fit)$r.squared
pVal <- anova(fit)$'Pr(>F)'[1]

I use EclipseLink. This JPA allows the following way for the native queries:

Query q = em.createNativeQuery("SELECT * FROM mytable where username = ?username");
q.setParameter("username", "test");
q.getResultList();

How about this? Bootstrap 4

<div class="row justify-content-end">
    <div class="col-3">
        The content is positioned as if there was
        "col-9" classed div appending this one.
    </div>
</div>

You can get good Time Series graphs in Excel, the way you want, but you have to work with a few quirks.

1. Be sure to select "Scatter Graph" (with a line option). This is needed if you have non-uniform time stamps, and will scale the X-axis accordingly.

2. In your data, you need to add a column with the mid-point. Here's what I did with your sample data. (This trick ensures that the data gets plotted at the mid-point, like you desire.)

3. You can format the x-axis options with this menu. (Chart->Design->Layout)

4. Select "Axes" and go to Primary Horizontal Axis, and then select "More Primary Horizontal Axis Options"

5. Set up the options you wish. (Fix the starting and ending points.)

6. And you will get a graph such as the one below.

You can then tweak many of the options, label the axes better etc, but this should get you started.

Hope this helps you move forward.

Sound like you just have an issue with the path. Include the full path, if you use backslashes they need to be escaped: "C:\\folder\\folder\\Desktop\\file.csv" or "C:/folder/folder/Desktop/file.csv".

myfile = read.csv("C:/folder/folder/Desktop/file.csv")  # or read.table()

It may also be wise to avoid spaces and symbols in your file names, though I'm fairly certain spaces are OK.

Replace following

curl_setopt ($setuploginurl, CURLOPT_SSLVERSION, 'CURL_SSLVERSION_TLSv1_2');

With

curl_setopt ($ch, CURLOPT_SSLVERSION, 6);

Should work flawlessly.

There's software for content-based image retrieval, which does (partially) what you need. All references and explanations are linked from the project site and there's also a short text book (Kindle): LIRE

From your question, you are running python2.7 and Cygwin.

Python should be installed for windows, which from your question it seems it is. If "which python" prints out /usr/bin/python , then from the bash prompt you are running the cygwin version.

Set the Python Environmental variables appropriately , for instance in my case:

PY_HOME=C:\opt\Python27
PYTHONPATH=C:\opt\Python27;c:\opt\Python27\Lib

In that case run cygwin setup and uninstall everything python. After that run "which pydoc", if it shows

/usr/bin/pydoc

Replace /usr/bin/pydoc with

#! /bin/bash
 /cygdrive/c/WINDOWS/system32/cmd /c %PYTHONHOME%\Scripts\\pydoc.bat

Then add this to $PY_HOME/Scripts/pydoc.bat

rem wrapper for pydoc on Win32
@python c:\opt\Python27\Lib\pydoc.py %*

Now when you type in the cygwin bash prompt you should see:

$ pydoc
 pydoc - the Python documentation tool

 pydoc.py <name> ...
   Show text documentation on something.  <name> 
   may be the name of a Python keyword, topic,
   function, module, or package, or a dotted
   reference to a class or function within a
   module or module in a package.
...

Keep the secret in firebase database and get from it when app starts , It is far better than calling a web service .

leading 0 means this is octal constant, not the decimal one. and you need an octal to change file mode.

permissions are a bit mask, for example, rwxrwx--- is 111111000 in binary, and it's very easy to group bits by 3 to convert to the octal, than calculate the decimal representation.

0644 (octal) is 0.110.100.100 in binary (i've added dots for readability), or, as you may calculate, 420 in decimal.

Through a combination of the suggestions I got, I came up with this:

    private void DrawLetter()
    {
        Graphics g = this.CreateGraphics();

        float width = ((float)this.ClientRectangle.Width);
        float height = ((float)this.ClientRectangle.Width);

        float emSize = height;

        Font font = new Font(FontFamily.GenericSansSerif, emSize, FontStyle.Regular);

        font = FindBestFitFont(g, letter.ToString(), font, this.ClientRectangle.Size);

        SizeF size = g.MeasureString(letter.ToString(), font);
        g.DrawString(letter, font, new SolidBrush(Color.Black), (width-size.Width)/2, 0);

    }

    private Font FindBestFitFont(Graphics g, String text, Font font, Size proposedSize)
    {
        // Compute actual size, shrink if needed
        while (true)
        {
            SizeF size = g.MeasureString(text, font);

            // It fits, back out
            if (size.Height <= proposedSize.Height &&
                 size.Width <= proposedSize.Width) { return font; }

            // Try a smaller font (90% of old size)
            Font oldFont = font;
            font = new Font(font.Name, (float)(font.Size * .9), font.Style);
            oldFont.Dispose();
        }
    }

So far, this works flawlessly.

The only thing I would change is to move the FindBestFitFont() call to the OnResize() event so that I'm not calling it every time I draw a letter. It only needs to be called when the control size changes. I just included it in the function for completeness.

For those who are interested in Pythonic functional way:

from datetime import date, timedelta
from itertools import count, takewhile

for d in takewhile(lambda x: x<=date(2009,6,9), map(lambda x:date(2009,5,30)+timedelta(days=x), count())):
    print(d)

The text uses combining characters, also known as combining marks. See section 2.11 of Combining Characters in the Unicode Standard (PDF).

In Unicode, character rendering does not use a simple character cell model where each glyph fits into a box with given height. Combining marks may be rendered above, below, or inside a base character

So you can easily construct a character sequence, consisting of a base character and “combining above” marks, of any length, to reach any desired visual height, assuming that the rendering software conforms to the Unicode rendering model. Such a sequence has no meaning of course, and even a monkey could produce it (e.g., given a keyboard with suitable driver).

And you can mix “combining above” and “combining below” marks.

The sample text in the question starts with:

• LATIN CAPITAL LETTER H - H
• COMBINING LATIN SMALL LETTER T - ͭ
• COMBINING GREEK KORONIS - ̓
• COMBINING COMMA ABOVE - ̓
• COMBINING DOT ABOVE - ̇

app = Flask(__name__, static_folder="your path to static")

If you have templates in your root directory, placing the app=Flask(name) will work if the file that contains this also is in the same location, if this file is in another location, you will have to specify the template location to enable Flask to point to the location

Faced the same problem. Probably it could be a solution:

<select id="select-1">
    <option>One</option>
    <option>Two</option>
    <option>Three</option>
</select>
<label for="select-1"></label>

#select-1 {
    ...
}

#select-1 + label:after {
    ...
}

Yes, that is fine. $_POST is just another variable, except it has (super)global scope.

$_POST = array();

...will be quite enough. The loop is useless. It's probably best to keep it as an array rather than unset it, in case other files are attempting to read it and assuming it is an array.

As of Sql Server 2012, you can use the following query:

SELECT SERVERPROPERTY('INSTANCEDEFAULTDATAPATH') as [Default_data_path], SERVERPROPERTY('INSTANCEDEFAULTLOGPATH') as [Default_log_path];

(This was taken from a comment at http://technet.microsoft.com/en-us/library/ms174396.aspx, and tested.)

Actually there is a way to just white-list all nested parameters.

params.require(:widget).permit(:name, :description).tap do |whitelisted|
  whitelisted[:position] = params[:widget][:position]
  whitelisted[:properties] = params[:widget][:properties]
end

This method has advantage over other solutions. It allows to permit deep-nested parameters.

While other solutions like:

params.require(:person).permit(:name, :age, pets_attributes: [:id, :name, :category])

Don't.

Try remove scrollChildLayout from its parent view first?

scrollview.removeView(scrollChildLayout)

Or remove all the child from the parent view, and add them again.

scrollview.removeAllViews()

An easy way is changing the input type and change it back again.

Something like this:

var input = $('#attachments');
input.prop('type', 'text');
input.prop('type', 'file')

You can determine whether a specified file exists using the Exists method of the File class in the System.IO namespace:

bool System.IO.File.Exists(string path)

You can find the documentation here on MSDN.

Example:

using System;
using System.IO;

class Test
{
    public static void Main()
    {
        string resumeFile = @"c:\ResumesArchive\923823.txt";
        string newFile = @"c:\ResumesImport\newResume.txt";

You can set a callback function for the onSubmit event of the form and check the contents of each field. If it contains nothing you can then fill it with the string "empty":

<form name="my_form" action="validate.php" onsubmit="check()">
    <input type="text" name="text1" />
    <input type="submit" value="submit" />
</form>

and in your js:

function check() {
    if(document.forms["my_form"]["text1"].value == "")
        document.forms["my_form"]["text1"].value = "empty";
}

There are several tools which can import Excel to SQL Server.

I am using DbTransfer (http://www.dbtransfer.com/Products/DbTransfer) to do the job. It's primarily focused on transfering data between databases and excel, xml, etc...

I have tried the openrowset method and the SQL Server Import / Export Assitant before. But I found these methods to be unnecessary complicated and error prone in constrast to doing it with one of the available dedicated tools.

On invoking overridable method from constructors

Simply put, this is wrong because it unnecessarily opens up possibilities to MANY bugs. When the @Override is invoked, the state of the object may be inconsistent and/or incomplete.

A quote from Effective Java 2nd Edition, Item 17: Design and document for inheritance, or else prohibit it:

There are a few more restrictions that a class must obey to allow inheritance. Constructors must not invoke overridable methods, directly or indirectly. If you violate this rule, program failure will result. The superclass constructor runs before the subclass constructor, so the overriding method in the subclass will be invoked before the subclass constructor has run. If the overriding method depends on any initialization performed by the subclass constructor, the method will not behave as expected.

Here's an example to illustrate:

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

        abstract class Base {
            Base() {
                overrideMe();
            }
            abstract void overrideMe(); 
        }

        class Child extends Base {

            final int x;

            Child(int x) {
                this.x = x;
            }

            @Override
            void overrideMe() {
                System.out.println(x);
            }
        }
        new Child(42); // prints "0"
    }
}

Here, when Base constructor calls overrideMe, Child has not finished initializing the final int x, and the method gets the wrong value. This will almost certainly lead to bugs and errors.

On object construction with many parameters

Constructors with many parameters can lead to poor readability, and better alternatives exist.

Here's a quote from Effective Java 2nd Edition, Item 2: Consider a builder pattern when faced with many constructor parameters:

Traditionally, programmers have used the telescoping constructor pattern, in which you provide a constructor with only the required parameters, another with a single optional parameters, a third with two optional parameters, and so on...

The telescoping constructor pattern is essentially something like this:

public class Telescope {
    final String name;
    final int levels;
    final boolean isAdjustable;

    public Telescope(String name) {
        this(name, 5);
    }
    public Telescope(String name, int levels) {
        this(name, levels, false);
    }
    public Telescope(String name, int levels, boolean isAdjustable) {       
        this.name = name;
        this.levels = levels;
        this.isAdjustable = isAdjustable;
    }
}

And now you can do any of the following:

new Telescope("X/1999");
new Telescope("X/1999", 13);
new Telescope("X/1999", 13, true);

You can't, however, currently set only the name and isAdjustable, and leaving levels at default. You can provide more constructor overloads, but obviously the number would explode as the number of parameters grow, and you may even have multiple boolean and int arguments, which would really make a mess out of things.

As you can see, this isn't a pleasant pattern to write, and even less pleasant to use (What does "true" mean here? What's 13?).

Bloch recommends using a builder pattern, which would allow you to write something like this instead:

Telescope telly = new Telescope.Builder("X/1999").setAdjustable(true).build();

Note that now the parameters are named, and you can set them in any order you want, and you can skip the ones that you want to keep at default values. This is certainly much better than telescoping constructors, especially when there's a huge number of parameters that belong to many of the same types.

• When would you use the Builder Pattern?
• Is this a well known design pattern? What is its name?

Well it does not work if the XML file (starting by the standard PI:

<?xml-stylesheet type="text/xsl" href="..."?>

for referencing the XSL stylesheet) is served as "application/xml". In that case, Chrome will still download the referenced XSL stylesheet, but nothing will be rendered, as it will silently change the document types from "application/xml" into "Document" (!??) and "text/xsl" into "Stylesheet" (!??), and then will attempt to render the XML document as if it was an HTML(5) document, without running first its XSLT processor. And Nothing at all will be displayed in the screen (whose content will continue to show the previous page from which the XML page was referenced, and will continue spinning the icon, as if the document was never completely loaded.

You can perfectly use the Chrome console, that shows that all resources are loaded, but they are incorrectly interpreted.

So yes, Chrome currently only render XML files (with its optional leading XSL stylesheet declaration), only if it is served as "text/xml", but not as "application/xml" as it should for client-side rendered XML with an XSL declaration.

For XML files served as "text/xml" or "application/xml" and that do not contain an XSL stylesheet declaration, Chrome should still use a default stylesheet to render it as a DOM tree, or at least as its text source. But it does not, and here again it attempts to render it as if it was HTML, and bugs immediately on many scripts (including a default internal one) that attempt to access to "document.body" for handling onLoad events and inject some javascript handler in it.

An example of site that does not work as expected (the Common Lisp documentation) in Chrome, but works in IE which supports client-side XSLT:

http://common-lisp.net/project/bknr/static/lmman/toc.html

This index page above is displayed correctly, but all links will drive to XML documents with a basic XSL declaration to an existing XSL stylesheet document, and you can wait indefinitely, thinking that the chapters have problems to be downloaded. All you can do to read the docuemntation is to open the console and read the source code in the Resources tab.

mysql -h "hostname" -u usr_name -pPASSWD "db_name" < sql_script_file

(use full path for sql_script_file if needed)

If you want to redirect the out put to a file

INSERT INTO exampleTbl VALUES('he doesn''t work for me')

If you're adding a record through ASP.NET, you can use the SqlParameter object to pass in values so you don't have to worry about the apostrophe's that users enter in.

I just stumbled upon this great post. If you are just checking whether the data is of string type then maybe we can skip the loop and use this struct (in my humble opinion)

public static bool IsStringType(object data)
    {
        return (data.GetType().GetProperties().Where(x => x.PropertyType == typeof(string)).FirstOrDefault() != null);
    }

Char or varchar- it is used to enter texual data where the length can be indicated in brackets Eg- name char (20)

MySQL casts to Decimal:

Cast bare integer to decimal:

select cast(9 as decimal(4,2));       //prints 9.00

Cast Integers 8/5 to decimal:

select cast(8/5 as decimal(11,4));    //prints 1.6000

Cast string to decimal:

select cast(".885" as decimal(11,3));   //prints 0.885

Cast two int variables into a decimal

mysql> select 5 into @myvar1;
Query OK, 1 row affected (0.00 sec)

mysql> select 8 into @myvar2;
Query OK, 1 row affected (0.00 sec)

mysql> select @myvar1/@myvar2;   //prints 0.6250

Cast decimal back to string:

select cast(1.552 as char(10));   //shows "1.552"

function getDefaultDate(curDate){
var dt = new Date(curDate);`enter code here`
var date = dt.getDate();
var month = dt.getMonth();
var year = dt.getFullYear();
if (month.toString().length == 1) {
    month = "0" + month
}
if (date.toString().length == 1) {
    date = "0" + date
}
return year.toString() + "-" + month.toString() + "-" + date.toString();
}

In function pass your date string.

None of those worked for me. Try this.

You can force the annotation library in your test using:

androidTestCompile 'com.android.support:support-annotations:23.1.0'

Something like this:

  // Force usage of support annotations in the test app, since it is internally used by the runner module.
  androidTestCompile 'com.android.support:support-annotations:23.1.0'
  androidTestCompile 'com.android.support.test:runner:0.4.1'
  androidTestCompile 'com.android.support.test:rules:0.4.1'
  androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.1'
  androidTestCompile 'com.android.support.test.espresso:espresso-intents:2.2.1'
  androidTestCompile 'com.android.support.test.espresso:espresso-web:2.2.1'

Another solution is to use this in the top level file:

configurations.all {
    resolutionStrategy.force 'com.android.support:support-annotations:23.1.0'
}

MS Expression Encoder can do mp4/h.264. not sure about ogg though.

You must have got the idea why you are getting this problem after going through above answers.

Can JAX-RS do Asynchronous Request like JAX-WS?

Yes, it can surely do use @Async

Can JAX-RS access a web service that is not running on the Java platform, and vice versa?

Yes, it can Do

What does it mean by "REST is particularly useful for limited-profile devices, such as PDAs and mobile phones"?

It is mainly use for public apis it depends on which approach you want to use.

What does it mean by "JAX-RS do not require XML messages or WSDL service–API definitions?

It has its own standards WADL(Web application Development Language) it has http request by which you can access resources they are altogether created by different mindset,In case in Jax-Rs you have to think of exposing resources

The thread you linked to does answer the question for you. You need to target the a elements themselves. E.g.

.nav.navbar-nav.navbar-right a {
    color: blue;
}

If that doesn't work, it just needs to be more specific. E.g.

.nav.navbar-nav.navbar-right li a {
    color: blue;
}

You don't need a batch file, just do this from powershell :

powershell -C "gci | % {rni $_.Name ($_.Name -replace 'Vacation2010', 'December')}"

I noticed that there is no selected feature in datalist. It only gives you choice but can't have a default option. You can't show the selected option on the next page either.

Now in eclipse Neon this feature is present. No need of any special settings or configuation .On Ctrl+Space the code suggestion is available

You have something like this:

URIBuilder builder = new URIBuilder();
builder.setScheme("http").setHost("www.google.com").setPath("/search")
    .setParameter("q", "httpclient")
    .setParameter("btnG", "Google Search")
    .setParameter("aq", "f")
    .setParameter("oq", "");
URI uri = builder.build();
HttpGet httpget = new HttpGet(uri);
System.out.println(httpget.getURI());

Slight tweak to answer from @divbyzero above to fix sonar security warnings

CloseableHttpClient getInsecureHttpClient() throws GeneralSecurityException {
            TrustStrategy trustStrategy = (chain, authType) -> true;

            HostnameVerifier hostnameVerifier = (hostname, session) -> hostname.equalsIgnoreCase(session.getPeerHost());

            return HttpClients.custom()
                    .setSSLSocketFactory(new SSLConnectionSocketFactory(new SSLContextBuilder().loadTrustMaterial(trustStrategy).build(), hostnameVerifier))
                    .build();
        }

The solution for me was to change the .NET framework version in the Application Pools from v4.0 to v2.0 for the Default App Pool:

using (var conn = new SqlConnection(SomeConnectionString))
using (var cmd = conn.CreateCommand())
{
    conn.Open();
    cmd.CommandText = "SELECT * FROM learer WHERE id = @id";
    cmd.Parameters.AddWithValue("@id", index);
    using (var reader = cmd.ExecuteReader())
    {
        if (reader.Read())
        {
            learerLabel.Text = reader.GetString(reader.GetOrdinal("somecolumn"))
        }
    }
}

Let's say, you want to select the first 10 rows. The easiest way to do it would be data[1:10, ].

However, let's say you try to retrieve the first 19 rows and see the what happens - you will have missing values

Inspired in this answer I came up with a bit more object-oriented solution.

This is only valid if you're intending to read characters

You can override BufferedReader and implement something like this:

public class SafeBufferedReader extends BufferedReader{

    private long millisTimeout;

    ( . . . )

    @Override
    public int read(char[] cbuf, int off, int len) throws IOException {
        try {
            waitReady();
        } catch(IllegalThreadStateException e) {
            return 0;
        }
        return super.read(cbuf, off, len);
    }

    protected void waitReady() throws IllegalThreadStateException, IOException {
        if(ready()) return;
        long timeout = System.currentTimeMillis() + millisTimeout;
        while(System.currentTimeMillis() < timeout) {
            if(ready()) return;
            try {
                Thread.sleep(100);
            } catch (InterruptedException e) {
                break; // Should restore flag
            }
        }
        if(ready()) return; // Just in case.
        throw new IllegalThreadStateException("Read timed out");
    }
}

Here's an almost complete example.

I'm returning 0 on some methods, you should change it to -2 to meet your needs, but I think that 0 is more suitable with BufferedReader contract. Nothing wrong happened, it just read 0 chars. readLine method is a horrible performance killer. You should create a entirely new BufferedReader if you actually want to use readLine. Right now, it is not thread safe. If someone invokes an operation while readLines is waiting for a line, it will produce unexpected results

I don't like returning -2 where I am. I'd throw an exception because some people may just be checking if int < 0 to consider EOS. Anyway, those methods claim that "can't block", you should check if that statement is actually true and just don't override'em.

Use RXTX.

On Debian install librxtx-java by typing:

sudo apt-get install librxtx-java

On Fedora or Enterprise Linux install rxtx by typing:

sudo yum install rxtx

json = ( new Function("return " + jsonString) )(); 

try this code it might be useful -

<%# ((DataBinder.Eval(Container.DataItem,"ImageFilename").ToString()=="") ? "" :"<a
 href="+DataBinder.Eval(Container.DataItem, "link")+"><img
 src='/Images/Products/"+DataBinder.Eval(Container.DataItem,
 "ImageFilename")+"' border='0' /></a>")%>

Adding this link in the open

$(this).parent().appendTo($("form:first"));

works perfectly.

You need to access the underlying buffer:

printf("%s\n", someString.c_str());

Or better use cout << someString << endl; (you need to #include <iostream> to use cout)

Additionally you might want to import the std namespace using using namespace std; or prefix both string and cout with std::.

Please make sure your code is fine. I too got stuck in this problem once and tried the solution accepted here but in vain. So I wrote my code again. Apparently I was using a custom array list and adding the values from an array. I tried changing the ArrayList to accept the primitive values only and it worked.

While it may work on some platforms, be aware that platform.architecture is not always a reliable way to determine whether python is running in 32-bit or 64-bit. In particular, on some OS X multi-architecture builds, the same executable file may be capable of running in either mode, as the example below demonstrates. The quickest safe multi-platform approach is to test sys.maxsize on Python 2.6, 2.7, Python 3.x.

$ arch -i386 /usr/local/bin/python2.7
Python 2.7.9 (v2.7.9:648dcafa7e5f, Dec 10 2014, 10:10:46)

>>> import platform, sys
>>> platform.architecture(), sys.maxsize

In my case, I named an Entity of my Core Data Model the same as an Object. So: I defined an object "Event.h" and at the same time I had this entity called "Event". I ended up renaming the entity.

I can handle this way:

select to_number(to_char(sysdate,'MI')) - to_number(to_char(*YOUR_DATA_VALUE*,'MI')),max(exp_time)  from ...

Or if you want to the hour just change the MI;

select to_number(to_char(sysdate,'HH24')) - to_number(to_char(*YOUR_DATA_VALUE*,'HH24')),max(exp_time)  from ...

the others don't work for me. Good luck.

Slight variation, main difference being to set the primary key field ("varname") to null, which produces a warning but works. By setting the primary key to null, the auto-increment works when inserting the record in the last statement.

This code also cleans up previous attempts, and can be run more than once without problems:

DELETE FROM `tbl` WHERE varname="primary key value for new record";
DROP TABLE tmp;
CREATE TEMPORARY TABLE tmp SELECT * FROM `tbl` WHERE varname="primary key value for old record";
UPDATE tmp SET varname=NULL;
INSERT INTO `tbl` SELECT * FROM tmp;

Linux:

mvn validate clean install | egrep -v "(^\[INFO\])"

or

mvn validate clean install | egrep -v "(^\[INFO\]|^\[DEBUG\])"

Windows:

mvn validate clean install | findstr /V /R "^\[INFO\] ^\[DEBUG\]"

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

Hello
\
\
\
World!

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

World!

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

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

To use the strict ISO8601, you can use the s (Sortable) format string:

 myDate.ToString("s"); // example 2009-06-15T13:45:30

It's a short-hand to this custom format string:

myDate.ToString("yyyy'-'MM'-'dd'T'HH':'mm':'ss");

And of course, you can build your own custom format strings.

Yes, a T... is only a syntactic sugar for a T[].

JLS 8.4.1 Format parameters

The last formal parameter in a list is special; it may be a variable arity parameter, indicated by an elipsis following the type.

If the last formal parameter is a variable arity parameter of type T, it is considered to define a formal parameter of type T[]. The method is then a variable arity method. Otherwise, it is a fixed arity method. Invocations of a variable arity method may contain more actual argument expressions than formal parameters. All the actual argument expressions that do not correspond to the formal parameters preceding the variable arity parameter will be evaluated and the results stored into an array that will be passed to the method invocation.

Here's an example to illustrate:

public static String ezFormat(Object... args) {
    String format = new String(new char[args.length])
        .replace("\0", "[ %s ]");
    return String.format(format, args);
}
public static void main(String... args) {
    System.out.println(ezFormat("A", "B", "C"));
    // prints "[ A ][ B ][ C ]"
}

And yes, the above main method is valid, because again, String... is just String[]. Also, because arrays are covariant, a String[] is an Object[], so you can also call ezFormat(args) either way.

Varargs gotchas #1: passing null

How varargs are resolved is quite complicated, and sometimes it does things that may surprise you.

Consider this example:

static void count(Object... objs) {
    System.out.println(objs.length);
}

count(null, null, null); // prints "3"
count(null, null); // prints "2"
count(null); // throws java.lang.NullPointerException!!!

Due to how varargs are resolved, the last statement invokes with objs = null, which of course would cause NullPointerException with objs.length. If you want to give one null argument to a varargs parameter, you can do either of the following:

count(new Object[] { null }); // prints "1"
count((Object) null); // prints "1"

The following is a sample of some of the questions people have asked when dealing with varargs:

• bug with varargs and overloading?

Vararg gotchas #2: adding extra arguments

As you've found out, the following doesn't "work":

    String[] myArgs = { "A", "B", "C" };
    System.out.println(ezFormat(myArgs, "Z"));
    // prints "[ [Ljava.lang.String;@13c5982 ][ Z ]"

Because of the way varargs work, ezFormat actually gets 2 arguments, the first being a String[], the second being a String. If you're passing an array to varargs, and you want its elements to be recognized as individual arguments, and you also need to add an extra argument, then you have no choice but to create another array that accommodates the extra element.

Here are some useful helper methods:

static <T> T[] append(T[] arr, T lastElement) {
    final int N = arr.length;
    arr = java.util.Arrays.copyOf(arr, N+1);
    arr[N] = lastElement;
    return arr;
}
static <T> T[] prepend(T[] arr, T firstElement) {
    final int N = arr.length;
    arr = java.util.Arrays.copyOf(arr, N+1);
    System.arraycopy(arr, 0, arr, 1, N);
    arr[0] = firstElement;
    return arr;
}

Now you can do the following:

    String[] myArgs = { "A", "B", "C" };
    System.out.println(ezFormat(append(myArgs, "Z")));
    // prints "[ A ][ B ][ C ][ Z ]"

    System.out.println(ezFormat(prepend(myArgs, "Z")));
    // prints "[ Z ][ A ][ B ][ C ]"

Varargs gotchas #3: passing an array of primitives

It doesn't "work":

    int[] myNumbers = { 1, 2, 3 };
    System.out.println(ezFormat(myNumbers));
    // prints "[ [I@13c5982 ]"

Varargs only works with reference types. Autoboxing does not apply to array of primitives. The following works:

    Integer[] myNumbers = { 1, 2, 3 };
    System.out.println(ezFormat(myNumbers));
    // prints "[ 1 ][ 2 ][ 3 ]"

You can use Environment.Exit(0) and Application.Exit.

Environment.Exit(): terminates this process and gives the underlying operating system the specified exit code.

This is the complete answer to my question. I had originally marked @Colin Williams' answer as the correct answer, as it helped me get to the complete solution. A community member, @Slipp D. Thompson edited my question, after about 2.5 years of me having asked it, and told me I was abusing SO's Q & A format. He also told me to separately post this as the answer. So here's the complete answer that solved my problem:

@Colin Williams, thank you! Your answer and the article you linked out to gave me a lead to try something with CSS.

So, I was using translate3d before. It produced unwanted results. Basically, it would chop off and NOT RENDER elements that were offscreen, until I interacted with them. So, basically, in landscape orientation, half of my site that was offscreen was not being shown. This is a iPad web app, owing to which I was in a fix.

Applying translate3d to relatively positioned elements solved the problem for those elements, but other elements stopped rendering, once offscreen. The elements that I couldn't interact with (artwork) would never render again, unless I reloaded the page.

The complete solution:

*:not(html) {
    -webkit-transform: translate3d(0, 0, 0);
}

Now, although this might not be the most "efficient" solution, it was the only one that works. Mobile Safari does not render the elements that are offscreen, or sometimes renders erratically, when using -webkit-overflow-scrolling: touch. Unless a translate3d is applied to all other elements that might go offscreen owing to that scroll, those elements will be chopped off after scrolling.

So, thanks again, and hope this helps some other lost soul. This surely helped me big time!

For debugging purpose I use:

console.debug("%o", data);

If anyone find shorter code, and preferably one that is able to perform this for all existing databases, extra kudos.

Using curl:

curl -v \
    -F "r=releases" \
    -F "g=com.acme.widgets" \
    -F "a=widget" \
    -F "v=0.1-1" \
    -F "p=tar.gz" \
    -F "file=@./widget-0.1-1.tar.gz" \
    -u myuser:mypassword \

You can see what the parameters mean here: https://support.sonatype.com/entries/22189106-How-can-I-programatically-upload-an-artifact-into-Nexus-

To make the permissions for this work, I created a new role in the admin GUI and I added two privileges to that role: Artifact Download and Artifact Upload. The standard "Repo: All Maven Repositories (Full Control)"-role is not enough. You won't find this in the REST API documentation that comes bundled with the Nexus server, so these parameters might change in the future.

On a Sonatype JIRA issue, it was mentioned that they "are going to overhaul the REST API (and the way it's documentation is generated) in an upcoming release, most likely later this year".

syslog() generates a log message, which will be distributed by syslogd.

The file to configure syslogd is /etc/syslog.conf. This file will tell your where the messages are logged.

_{All standard references below refers to N4659: March 2017 post-Kona working draft/C++17 DIS.}

Typedef declarations can, whereas alias declarations cannot, be used as initialization statements

But, with the first two non-template examples, are there any other subtle differences in the standard?

• Differences in semantics: none.
• Differences in allowed contexts: some⁽¹⁾.

^{(1) In addition to the examples of alias templates, which has already been mentioned in the original post.}

Same semantics

As governed by [dcl.typedef]/2 [extract, emphasis mine]

[dcl.typedef]/2 A typedef-name can also be introduced by an alias-declaration. The identifier following the using keyword becomes a typedef-name and the optional attribute-specifier-seq following the identifier appertains to that typedef-name. Such a typedef-name has the same semantics as if it were introduced by the typedef specifier. [...]

a typedef-name introduced by an alias-declaration has the same semantics as if it were introduced by the typedef declaration.

Subtle difference in allowed contexts

However, this does not imply that the two variations have the same restrictions with regard to the contexts in which they may be used. And indeed, albeit a corner case, a typedef declaration is an init-statement and may thus be used in contexts which allow initialization statements

// C++11 (C++03) (init. statement in for loop iteration statements).
for(typedef int Foo; Foo{} != 0;) {}

// C++17 (if and switch initialization statements).
if (typedef int Foo; true) { (void)Foo{}; }
//  ^^^^^^^^^^^^^^^ init-statement

switch(typedef int Foo; 0) { case 0: (void)Foo{}; }
//     ^^^^^^^^^^^^^^^ init-statement

// C++20 (range-based for loop initialization statements).
std::vector<int> v{1, 2, 3};
for(typedef int Foo; Foo f : v) { (void)f; }
//  ^^^^^^^^^^^^^^^ init-statement

for(typedef struct { int x; int y;} P;
//  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ init-statement
    auto [x, y] : {P{1, 1}, {1, 2}, {3, 5}}) { (void)x; (void)y; }

whereas an alias-declaration is not an init-statement, and thus may not be used in contexts which allows initialization statements

// C++ 11.
for(using Foo = int; Foo{} != 0;) {}
//  ^^^^^^^^^^^^^^^ error: expected expression

// C++17 (initialization expressions in switch and if statements).
if (using Foo = int; true) { (void)Foo{}; }
//  ^^^^^^^^^^^^^^^ error: expected expression

switch(using Foo = int; 0) { case 0: (void)Foo{}; }
//     ^^^^^^^^^^^^^^^ error: expected expression

// C++20 (range-based for loop initialization statements).
std::vector<int> v{1, 2, 3};
for(using Foo = int; Foo f : v) { (void)f; }
//  ^^^^^^^^^^^^^^^ error: expected expression

First of all, when your first initial window is loaded, it is cached. Therefore, when creating a new window from the first window, the contents of the new window are not loaded from the server, but are loaded from the cache. Consequently, no onload event occurs when you create the new window.

However, in this case, an onpageshow event occurs. It always occurs after the onload event and even when the page is loaded from cache. Plus, it now supported by all major browsers.

 window.popup = window.open($(this).attr('href'), 'Ad', 'left=20,top=20,width=500,height=500,toolbar=1,resizable=0');
 $(window.popup).onpageshow = function() {
     alert("Popup has loaded a page");
 };

The w3school website elaborates more on this:

The onpageshow event is similar to the onload event, except that it occurs after the onload event when the page first loads. Also, the onpageshow event occurs every time the page is loaded, whereas the onload event does not occur when the page is loaded from the cache.

One of the reason may be if any one of table column have an underscore(_) in its name . That is considered as invalid characters by the JDBC . Rename the column by a ALTER Command and change in your code SQL , that will fix .

You can also configure your component like this :

package mypackage;
import org.springframework.context.annotation.Configuration;
   @Configuration
   public class MyConstructorClassConfig {


   @Bean
   public MyConstructorClass myConstructorClass(){
      return new myConstructorClass("foobar");
   }
  }
}

With the Bean annotation, you are telling Spring to register the returned bean in the BeanFactory.

So you can autowire it as you wish.

I just had the same issue and it seems it also shows this message if the resource cannot be found.

In my case I had updated the API, but forgotten to redeploy. The issue was resolved after deploying the updated API to my stage.

In HTML5 there is no scrolling attribute because "its function is better handled by CSS" see http://www.w3.org/TR/html5-diff/ for other changes. Well and the CSS solution:

CSS solution:

HTML4's scrolling="no" is kind of an alias of the CSS's overflow: hidden, to do so it is important to set size attributes width/height:

iframe.noScrolling{
  width: 250px; /*or any other size*/
  height: 300px; /*or any other size*/
  overflow: hidden;
}

Add this class to your iframe and you're done:

<iframe src="http://www.example.com/" class="noScrolling"></iframe>

! IMPORTANT NOTE ! : overflow: hidden for <iframe> is not fully supported by all modern browsers yet(even chrome doesn't support it yet) so for now (2013) it's still better to use Transitional version and use scrolling="no" and overflow:hidden at the same time :)

UPDATE 2020: the above is still true, oveflow for iframes is still not supported by all majors

You can use fiddler as webdebugger http://www.telerik.com/fiddler/web-debugging

Fiddler is a debugging tool from telerik software, which helps you to intercept every request that is initiated from your machine.

Just use a onchnage Event for select box.

<select id="selectbox" name="" onchange="javascript:location.href = this.value;">
    <option value="https://www.yahoo.com/" selected>Option1</option>
    <option value="https://www.google.co.in/">Option2</option>
    <option value="https://www.gmail.com/">Option3</option>

</select>

And if selected option to be loaded at the page load then add some javascript code

<script type="text/javascript">
    window.onload = function(){
        location.href=document.getElementById("selectbox").value;
    }       
</script>

for jQuery: Remove the onchange event from <select> tag

jQuery(function () {
    // remove the below comment in case you need chnage on document ready
    // location.href=jQuery("#selectbox").val(); 
    jQuery("#selectbox").change(function () {
        location.href = jQuery(this).val();
    })
})

If you are writing a scraper and really don't care about the SSL certificate you can set it global:

import ssl

ssl._create_default_https_context = ssl._create_unverified_context

DO NOT USE IN PRODUCTION

This doesn't work and it shouldn't because it would be a giant security hole.

Have a look at the new File System API. It allows you to request access to a virtual, sandboxed filesystem governed by the browser. You will have to request your user to "upload" their file into the sandboxed filesystem once, but afterwards you can work with it very elegantly.

While this definitely is the future, it is still highly experimental and only works in Google Chrome as far as CanIUse knows.

Here is full component example

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

@Component({
  selector: 'app-text-box',
  template: `
        <h1>Text ({{textValue}})</h1>
        <input #textbox type="text" [(ngModel)]="textValue" required>
        <button (click)="logText(textbox.value)">Update Log</button>
        <button (click)="textValue=''">Clear</button>

        <h2>Template Reference Variable</h2>
        Type: '{{textbox.type}}', required: '{{textbox.hasAttribute('required')}}',
        upper: '{{textbox.value.toUpperCase()}}'

        <h2>Log <button (click)="log=''">Clear</button></h2>
        <pre>{{log}}</pre>`
})
export class TextComponent {

  textValue = 'initial value';
  log = '';

  logText(value: string): void {
    this.log += `Text changed to '${value}'\n`;
  }
}

Every webkit based browser should support the properties -webkit-margin-collapse. There are also subproperties to only set it for the top or bottom margin. You can give it the values collapse (default), discard (sets margin to 0 if there is a neighboring margin), and separate (prevents margin collapse).

I've tested that this works on 2014 versions of Chrome and Safari. Unfortunately, I don't think this would be supported in IE because it's not based on webkit.

Read Apple's Safari CSS Reference for a full explanation.

If you check Mozilla's CSS webkit extensions page, they list these properties as proprietary and recommend not to use them. This is because they're likely not going to go into standard CSS anytime soon and only webkit based browsers will support them.

dictc={"stName":"asas"}
keys=dictc.keys()
for key in list(keys):
    dictc[key.upper()] ='New value'
print(str(dictc))

In my case i wasn't exporting the module. module.exports = router;

Another thing to consider is that, since there is no multiple inheritance, if you want a class to be able to implement/inherit from your interface/abstract class, but inherit from another base class, use an interface.

Seaborn takes care of a lot of the manual work and automatically plots a gradient at the side of the chart etc.

import numpy as np
import seaborn as sns
import matplotlib.pylab as plt

uniform_data = np.random.rand(10, 12)
ax = sns.heatmap(uniform_data, linewidth=0.5)
plt.show()

Or, you can even plot upper / lower left / right triangles of square matrices, for example a correlation matrix which is square and is symmetric, so plotting all values would be redundant anyway.

corr = np.corrcoef(np.random.randn(10, 200))
mask = np.zeros_like(corr)
mask[np.triu_indices_from(mask)] = True
with sns.axes_style("white"):
    ax = sns.heatmap(corr, mask=mask, vmax=.3, square=True,  cmap="YlGnBu")
    plt.show()

Found this elsewhere here but this is a simple solution that works:

 WITH cte AS /* Declaring a new table named 'cte' to be a clone of your table */
 (SELECT *, ROW_NUMBER() OVER (PARTITION BY id ORDER BY val1 DESC) AS rn
 FROM MyTable /* Selecting only unique values based on the "id" field */
 )
 SELECT * /* Here you can specify several columns to retrieve */
 FROM cte
 WHERE rn = 1

I use HttpWebRequest to GET from the web service, which returns me a JSON string. It looks something like this for a GET:

// Returns JSON string
string GET(string url) 
{
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
    try {
        WebResponse response = request.GetResponse();
        using (Stream responseStream = response.GetResponseStream()) {
            StreamReader reader = new StreamReader(responseStream, System.Text.Encoding.UTF8);
            return reader.ReadToEnd();
        }
    }
    catch (WebException ex) {
        WebResponse errorResponse = ex.Response;
        using (Stream responseStream = errorResponse.GetResponseStream())
        {
            StreamReader reader = new StreamReader(responseStream, System.Text.Encoding.GetEncoding("utf-8"));
            String errorText = reader.ReadToEnd();
            // log errorText
        }
        throw;
    }
}

I then use JSON.Net to dynamically parse the string. Alternatively, you can generate the C# class statically from sample JSON output using this codeplex tool: http://jsonclassgenerator.codeplex.com/

POST looks like this:

// POST a JSON string
void POST(string url, string jsonContent) 
{
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
    request.Method = "POST";

    System.Text.UTF8Encoding encoding = new System.Text.UTF8Encoding();
    Byte[] byteArray = encoding.GetBytes(jsonContent);

    request.ContentLength = byteArray.Length;
    request.ContentType = @"application/json";

    using (Stream dataStream = request.GetRequestStream()) {
        dataStream.Write(byteArray, 0, byteArray.Length);
    }
    long length = 0;
    try {
        using (HttpWebResponse response = (HttpWebResponse)request.GetResponse()) {
            length = response.ContentLength;
        }
    }
    catch (WebException ex) {
        // Log exception and throw as for GET example above
    }
}

I use code like this in automated tests of our web service.

ant-contrib is evil; write a custom ant task.

ant-contrib is evil because it tries to convert ant from a declarative style to an imperative style. But xml makes a crap programming language.

By contrast a custom ant task allows you to write in a real language (Java), with a real IDE, where you can write unit tests to make sure you have the behavior you want, and then make a clean declaration in your build script about the behavior you want.

This rant only matters if you care about writing maintainable ant scripts. If you don't care about maintainability by all means do whatever works. :)

Jtf

You can create a pre-filled form URL from within the Form Editor, as described in the documentation for Drive Forms. You'll end up with a URL like this, for example:

https://docs.google.com/forms/d/--form-id--/viewform?entry.726721210=Mike+Jones&entry.787184751=1975-05-09&entry.1381372492&entry.960923899

buildUrls()

In this example, question 1, "Name", has an ID of 726721210, while question 2, "Birthday" is 787184751. Questions 3 and 4 are blank.

You could generate the pre-filled URL by adapting the one provided through the UI to be a template, like this:

function buildUrls() {
  var template = "https://docs.google.com/forms/d/--form-id--/viewform?entry.726721210=##Name##&entry.787184751=##Birthday##&entry.1381372492&entry.960923899";
  var ss = SpreadsheetApp.getActive().getSheetByName("Sheet1");  // Email, Name, Birthday
  var data = ss.getDataRange().getValues();

  // Skip headers, then build URLs for each row in Sheet1.
  for (var i = 1; i < data.length; i++ ) {
    var url = template.replace('##Name##',escape(data[i][1]))
                      .replace('##Birthday##',data[i][2].yyyymmdd());  // see yyyymmdd below
    Logger.log(url);  // You could do something more useful here.
  }
};

This is effective enough - you could email the pre-filled URL to each person, and they'd have some questions already filled in.

betterBuildUrls()

Instead of creating our template using brute force, we can piece it together programmatically. This will have the advantage that we can re-use the code without needing to remember to change the template.

Each question in a form is an item. For this example, let's assume the form has only 4 questions, as you've described them. Item [0] is "Name", [1] is "Birthday", and so on.

We can create a form response, which we won't submit - instead, we'll partially complete the form, only to get the pre-filled form URL. Since the Forms API understands the data types of each item, we can avoid manipulating the string format of dates and other types, which simplifies our code somewhat.

(EDIT: There's a more general version of this in How to prefill Google form checkboxes?)

/**
 * Use Form API to generate pre-filled form URLs
 */
function betterBuildUrls() {
  var ss = SpreadsheetApp.getActive();
  var sheet = ss.getSheetByName("Sheet1");
  var data = ss.getDataRange().getValues();  // Data for pre-fill

  var formUrl = ss.getFormUrl();             // Use form attached to sheet
  var form = FormApp.openByUrl(formUrl);
  var items = form.getItems();

  // Skip headers, then build URLs for each row in Sheet1.
  for (var i = 1; i < data.length; i++ ) {
    // Create a form response object, and prefill it
    var formResponse = form.createResponse();

    // Prefill Name
    var formItem = items[0].asTextItem();
    var response = formItem.createResponse(data[i][1]);
    formResponse.withItemResponse(response);

    // Prefill Birthday
    formItem = items[1].asDateItem();
    response = formItem.createResponse(data[i][2]);
    formResponse.withItemResponse(response);

    // Get prefilled form URL
    var url = formResponse.toPrefilledUrl();
    Logger.log(url);  // You could do something more useful here.
  }
};

yymmdd Function

Any date item in the pre-filled form URL is expected to be in this format: yyyy-mm-dd. This helper function extends the Date object with a new method to handle the conversion.

When reading dates from a spreadsheet, you'll end up with a javascript Date object, as long as the format of the data is recognizable as a date. (Your example is not recognizable, so instead of May 9th 1975 you could use 5/9/1975.)

// From http://blog.justin.kelly.org.au/simple-javascript-function-to-format-the-date-as-yyyy-mm-dd/
Date.prototype.yyyymmdd = function() {
  var yyyy = this.getFullYear().toString();                                    
  var mm = (this.getMonth()+1).toString(); // getMonth() is zero-based         
  var dd  = this.getDate().toString();             

  return yyyy + '-' + (mm[1]?mm:"0"+mm[0]) + '-' + (dd[1]?dd:"0"+dd[0]);
};

tony's approach does work for me but when do a console.log, the function getTableHeight get called too many time(sort, menu click...)

I modify it so the height is recalculated only when i add/remove rows. Note: tableData is the array of rows

$scope.getTableHeight = function() {
   var rowHeight = 30; // your row height
   var headerHeight = 30; // your header height
   return {
      height: ($scope.gridData.data.length * rowHeight + headerHeight) + "px"
   };
};

$scope.$watchCollection('tableData', function (newValue, oldValue) {
    angular.element(element[0].querySelector('.grid')).css($scope.getTableHeight());
});

Html

<div id="grid1" ui-grid="gridData" class="grid" ui-grid-auto-resize"></div>

How about the JQuery ScrollTo - see this sample code

Same with something more complex...getting the ec2 instance region from within the instance.

INSTANCE_REGION=$(curl -s 'http://169.254.169.254/latest/dynamic/instance-identity/document' | python -c "import sys, json; print json.load(sys.stdin)['region']")

echo $INSTANCE_REGION

Use:

Array.prototype.contains = function(x){
  var retVal = -1;

  // x is a primitive type
  if(["string","number"].indexOf(typeof x)>=0 ){ retVal = this.indexOf(x);}

  // x is a function
  else if(typeof x =="function") for(var ix in this){
    if((this[ix]+"")==(x+"")) retVal = ix;
  }

  //x is an object...
  else {
    var sx=JSON.stringify(x);
    for(var ix in this){
      if(typeof this[ix] =="object" && JSON.stringify(this[ix])==sx) retVal = ix;
    }
  }

  //Return False if -1 else number if numeric otherwise string
  return (retVal === -1)?false : ( isNaN(+retVal) ? retVal : +retVal);
}

I know it's not the best way to go, but since there is no native IComparable way to interact between objects, I guess this is as close as you can get to compare two entities in an array. Also, extending Array object might not be a wise thing to do, but sometimes it's OK (if you are aware of it and the trade-off).

At runtime, you know what style you want your button to have. So beforehand, in xml in the layout folder, you can have all ready to go buttons with the styles you need. So in the layout folder, you might have a file named: button_style_1.xml. The contents of that file might look like:

<?xml version="1.0" encoding="utf-8"?>
<Button
    android:id="@+id/styleOneButton"
    style="@style/FirstStyle" />

If you are working with fragments, then in onCreateView you inflate that button, like:

Button firstStyleBtn = (Button) inflater.inflate(R.layout.button_style_1, container, false);

where container is the ViewGroup container associated with the onCreateView method you override when creating your fragment.

Need two more such buttons? You create them like this:

Button secondFirstStyleBtn = (Button) inflater.inflate(R.layout.button_style_1, container, false);
Button thirdFirstStyleBtn = (Button) inflater.inflate(R.layout.button_style_1, container, false);

You can customize those buttons:

secondFirstStyleBtn.setText("My Second");
thirdFirstStyleBtn.setText("My Third");

Then you add your customized, stylized buttons to the layout container you also inflated in the onCreateView method:

_stylizedButtonsContainer = (LinearLayout) rootView.findViewById(R.id.stylizedButtonsContainer);

_stylizedButtonsContainer.addView(firstStyleBtn);
_stylizedButtonsContainer.addView(secondFirstStyleBtn);
_stylizedButtonsContainer.addView(thirdFirstStyleBtn);

And that's how you can dynamically work with stylized buttons.

try this:

         TextView calloutContent = new TextView(getApplicationContext());
         calloutContent.setTextColor(Color.BLACK);
         calloutContent.setSingleLine(false);
         calloutContent.setLines(2);
         calloutContent.setText(" line 1" + System.getProperty ("line.separator")+"  line2" );

From a purely "make it fit in the div" perspective, add the following to your table class (jsfiddle):

table-layout: fixed;
width: 100%;

Set your column widths as desired; otherwise, the fixed layout algorithm will distribute the table width evenly across your columns.

For quick reference, here are the table layout algorithms, emphasis mine:

• Fixed (source)

  With this (fast) algorithm, the horizontal layout of the table does not depend on the contents of the cells; it only depends on the table's width, the width of the columns, and borders or cell spacing.

• Automatic (source)

  In this algorithm (which generally requires no more than two passes), the table's width is given by the width of its columns [, as determined by content] (and intervening borders).
  
  [...] This algorithm may be inefficient since it requires the user agent to have access to all the content in the table before determining the final layout and may demand more than one pass.

Click through to the source documentation to see the specifics for each algorithm.

Two possible approaches:

1. I don't think popen() is part of the C++ standard (it's part of POSIX from memory), but it's available on every UNIX I've worked with (and you seem to be targeting UNIX since your command is ./some_command).

2. On the off-chance that there is no popen(), you can use system("./some_command >/tmp/some_command.out");, then use the normal I/O functions to process the output file.

I think this is a simple code in java which will show the string value in CSV after compile this code.

public class CsvWriter {

    public static void main(String args[]) {
        // File input path
        System.out.println("Starting....");
        File file = new File("/home/Desktop/test/output.csv");
        try {
            FileWriter output = new FileWriter(file);
            CSVWriter write = new CSVWriter(output);

            // Header column value
            String[] header = { "ID", "Name", "Address", "Phone Number" };
            write.writeNext(header);
            // Value
            String[] data1 = { "1", "First Name", "Address1", "12345" };
            write.writeNext(data1);
            String[] data2 = { "2", "Second Name", "Address2", "123456" };
            write.writeNext(data2);
            String[] data3 = { "3", "Third Name", "Address3", "1234567" };
            write.writeNext(data3);
            write.close();
        } catch (Exception e) {
            // TODO: handle exception
            e.printStackTrace();

        }

        System.out.println("End.");

    }
}

Read more about Bitwise and Bit Shift Operators

>>      Signed right shift
>>>     Unsigned right shift

The bit pattern is given by the left-hand operand, and the number of positions to shift by the right-hand operand. The unsigned right shift operator >>> shifts a zero into the leftmost position,

while the leftmost position after >> depends on sign extension.

In simple words >>> always shifts a zero into the leftmost position whereas >> shifts based on sign of the number i.e. 1 for negative number and 0 for positive number.

For example try with negative as well as positive numbers.

int c = -153;
System.out.printf("%32s%n",Integer.toBinaryString(c >>= 2));
System.out.printf("%32s%n",Integer.toBinaryString(c <<= 2));
System.out.printf("%32s%n",Integer.toBinaryString(c >>>= 2));
System.out.println(Integer.toBinaryString(c <<= 2));

System.out.println();

c = 153;
System.out.printf("%32s%n",Integer.toBinaryString(c >>= 2));
System.out.printf("%32s%n",Integer.toBinaryString(c <<= 2));
System.out.printf("%32s%n",Integer.toBinaryString(c >>>= 2));
System.out.printf("%32s%n",Integer.toBinaryString(c <<= 2));

output:

getTime() retrieves the milliseconds since Jan 1, 1970 GMT passed to the constructor. It should not be too hard to get the Unix time (same, but in seconds) from that.

The documentation for templating is partial, I watched the source.

The _.template function has 3 arguments:

1. String text : the template string
2. Object data : the evaluation data
3. Object settings : local settings, the _.templateSettings is the global settings object

If no data (or null) given, than a render function will be returned. It has 1 argument:

1. Object data : same as the data above

There are 3 regex patterns and 1 static parameter in the settings:

1. RegExp evaluate : "<%code%>" in template string
2. RegExp interpolate : "<%=code%>" in template string
3. RegExp escape : "<%-code%>"
4. String variable : optional, the name of the data parameter in the template string

The code in an evaluate section will be simply evaluated. You can add string from this section with the __p+="mystring" command to the evaluated template, but this is not recommended (not part of the templating interface), use the interpolate section instead of that. This type of section is for adding blocks like if or for to the template.

The result of the code in the interpolate section will added to the evaluated template. If null given back, then empty string will added.

The escape section escapes html with _.escape on the return value of the given code. So its similar than an _.escape(code) in an interpolate section, but it escapes with \ the whitespace characters like \n before it passes the code to the _.escape. I don't know why is that important, it's in the code, but it works well with the interpolate and _.escape - which doesn't escape the white-space characters - too.

By default the data parameter is passed by a with(data){...} statement, but this kind of evaluating is much slower than the evaluating with named variable. So naming the data with the variable parameter is something good...

For example:

var html = _.template(
    "<pre>The \"<% __p+=_.escape(o.text) %>\" is the same<br />" +
        "as the  \"<%= _.escape(o.text) %>\" and the same<br />" +
        "as the \"<%- o.text %>\"</pre>",
    {
        text: "<b>some text</b> and \n it's a line break"
    },
    {
        variable: "o"
    }
);

$("body").html(html);

results

The "<b>some text</b> and 
 it's a line break" is the same
as the "<b>some text</b> and 
 it's a line break" and the same
as the "<b>some text</b> and 
 it's a line break"

You can find here more examples how to use the template and override the default settings: http://underscorejs.org/#template

By template loading you have many options, but at the end you always have to convert the template into string. You can give it as normal string like the example above, or you can load it from a script tag, and use the .html() function of jquery, or you can load it from a separate file with the tpl plugin of require.js.

Another option to build the dom tree with laconic instead of templating.

Cheaper, Faster, and Idiomatic: str.contains

In recent versions of pandas, you can use string methods on the index and columns. Here, str.startswith seems like a good fit.

To remove all columns starting with a given substring:

df.columns.str.startswith('Test')
# array([ True, False, False, False])

df.loc[:,~df.columns.str.startswith('Test')]

  toto test2 riri
0    x     x    x
1    x     x    x

For case-insensitive matching, you can use regex-based matching with str.contains with an SOL anchor:

df.columns.str.contains('^test', case=False)
# array([ True, False,  True, False])

df.loc[:,~df.columns.str.contains('^test', case=False)] 

  toto riri
0    x    x
1    x    x

if mixed-types is a possibility, specify na=False as well.

This one doesn't alter the original newer branch, and gives you the opportunity to make further modifications before final commit.

git checkout new -b tmp
git merge -s ours old -m 'irrelevant'
git checkout old
git merge --squash tmp
git branch -D tmp
#do any other stuff you want
git add -A; git commit -m 'foo' #commit (or however you like)

You can force gcc to output directly to assembly code by adding the -S switch

gcc -S hello.c

The reason that this is happening is because the stack panel measures every child element with positive infinity as the constraint for the axis that it is stacking elements along. The child controls have to return how big they want to be (positive infinity is not a valid return from the MeasureOverride in either axis) so they return the smallest size where everything will fit. They have no way of knowing how much space they really have to fill.

If your view doesn’t need to have a scrolling feature and the answer above doesn't suit your needs, I would suggest implement your own panel. You can probably derive straight from StackPanel and then all you will need to do is change the ArrangeOverride method so that it divides the remaining space up between its child elements (giving them each the same amount of extra space). Elements should render fine if they are given more space than they wanted, but if you give them less you will start to see glitches.

If you want to be able to scroll the whole thing then I am afraid things will be quite a bit more difficult, because the ScrollViewer gives you an infinite amount of space to work with which will put you in the same position as the child elements were originally. In this situation you might want to create a new property on your new panel which lets you specify the viewport size, you should be able to bind this to the ScrollViewer’s size. Ideally you would implement IScrollInfo, but that starts to get complicated if you are going to implement all of it properly.

Also remember to set the 'Deployment target selection mode' to manual (Debug configurations -> target tab)

You can even use this one. worked well for me

$("#registerform").attr("action", "register.php?btnsubmit=Save") 
$('#registerform').submit();

this will submit btnsubmit =Save as GET value to register.php form.

Yes, you can add a UNIQUE constraint after the fact. However, if you have non-unique entries in your table Postgres will complain about it until you correct them.

In the example code below I use variables just to show how the command could be used for other situations.

FirstCol = 1
LastCol = FirstCol + 5
Range(Columns(FirstCol), Columns(LastCol)).Select

This error means the application pool to which your deployed application belongs is not in Integrated mode.

For powershell in Windows, you can add relative path + filename to --output flag:

While it's true that bool and tinyint(1) are functionally identical, bool should be the preferred option because it carries the semantic meaning of what you're trying to do. Also, many ORMs will convert bool into your programing language's native boolean type.

I have asked this question more than 6 years ago, and any answers I got had some flaws. Later I myself worked out a solution that I have been using for years since then. Now that I came across my own question again and I saw that it has many views, I'd like to share it because I think it may help others.

This problem mainly occurs on Master-Detail type of pages (can be old .master and .aspx pages) or (layout and views in asp.net) or any similar situation maybe on other web development languages, however always there is a master-detail pattern involved.

For the solution, I just add an array at the beginning of my page:

<script>var after = [];</script>

any function that requires jQuery or any other script that would run after this section, instead of running it, I just push it to this array:

after.push(function(){
     // code that requires scripts that will load later,
     //might be for example a jQuery selector or ...
}); 

and then at the very end of the page, right before closing the body tag (of course scripts are loaded by now) I run all the functions inside the (here named) after array:

<script>for(var i=0;i<after.length;i++)after[i]();</script>
</body>

I find this way very easy, simple and flawless.

PySpark provides various filtering options based on arithmetic, logical and other conditions. Presence of NULL values can hamper further processes. Removing them or statistically imputing them could be a choice.

Below set of code can be considered:

# Dataset is df
# Column name is dt_mvmt
# Before filtering make sure you have the right count of the dataset
df.count() # Some number

# Filter here
df = df.filter(df.dt_mvmt.isNotNull())

# Check the count to ensure there are NULL values present (This is important when dealing with large dataset)
df.count() # Count should be reduced if NULL values are present

#warpcontainer  {width:800px; height:auto; border: 1px solid #000; float:left; }
#warpcontainer2 {width:260px; height:auto; border: 1px solid #000; float:left; clear:both; margin-top:10px }

If you're looking to use the standard construct of element = element1 || element2 where JavaScript will return the first one that is truthy, you could do exactly that:

element = $('#someParentElement .somethingToBeFound') || $('#someParentElement .somethingElseToBeFound');

which would return the first element that is actually found. But a better way would probably be to use the jQuery selector comma construct (which returns an array of found elements) in this fashion:

element = $('#someParentElement').find('.somethingToBeFound, .somethingElseToBeFound')[0];

which will return the first found element.

I use that from time to time to find either an active element in a list or some default element if there is no active element. For example:

element = $('ul#someList').find('li.active, li:first')[0] 

which will return any li with a class of active or, should there be none, will just return the last li.

Either will work. There are potential performance penalties, though, as the || will stop processing as soon as it finds something truthy whereas the array approach will try to find all elements even if it has found one already. Then again, using the || construct could potentially have performance issues if it has to go through several selectors before finding the one it will return, because it has to call the main jQuery object for each one (I really don't know if this is a performance hit or not, it just seems logical that it could be). In general, though, I use the array approach when the selector is a rather long string.

Adding to @mob's answer:

Appending %N to date +%s gives us nanosecond accuracy:

start=`date +%s%N`;<command>;end=`date +%s%N`;echo `expr $end - $start`

Among several options for shading and tinting:

• For shades, multiply each component by 1/4, 1/2, 3/4, etc., of its previous value. The smaller the factor, the darker the shade.

• For tints, calculate (255 - previous value), multiply that by 1/4, 1/2, 3/4, etc. (the greater the factor, the lighter the tint), and add that to the previous value (assuming each.component is a 8-bit integer).

Note that color manipulations (such as tints and other shading) should be done in linear RGB. However, RGB colors specified in documents or encoded in images and video are not likely to be in linear RGB, in which case a so-called inverse transfer function needs to be applied to each of the RGB color's components. This function varies with the RGB color space. For example, in the sRGB color space (which can be assumed if the RGB color space is unknown), this function is roughly equivalent to raising each sRGB color component (ranging from 0 through 1) to a power of 2.2. (Note that "linear RGB" is not an RGB color space.)

See also Violet Giraffe's comment about "gamma correction".

In my case, what was causing the problem was an if else statement. After re-writing the conditions, the error 'near done' got away.

have a look at the below code snippet.

@RequestMapping(value = "edit.htm", method = RequestMethod.GET) 
    public ModelAndView edit(@RequestParam("id") String id) throws Exception {
        ModelMap modelMap = new ModelMap();
        modelMap.addAttribute("user", userinfoDao.findById(id));
        return new ModelAndView("edit", modelMap);      
    }

UserInfo Project on GitLab

Using Hibernate 4 and slf4j/log4j2 , I tried adding the following in my log4j2.xml configuration :

<Logger name="org.hibernate.type.descriptor.sql.BasicBinder" level="trace" additivity="false"> 
    <AppenderRef ref="Console"/> 
</Logger> 
<Logger name="org.hibernate.type.EnumType" level="trace" additivity="false"> 
    <AppenderRef ref="Console"/>
</Logger>

But without success.

I found out through this thread that the jboss-logging framework used by hibernate needed to be configured in order to log through slf4j. I added the following argument to the VM arguments of the application:

-Dorg.jboss.logging.provider=slf4j

And it worked like a charm.

Standard Subversion layout

Create a git clone of that includes your Subversion trunk, tags, and branches with

git svn clone http://svn.example.com/project -T trunk -b branches -t tags

The --stdlayout option is a nice shortcut if your Subversion repository uses the typical structure:

git svn clone http://svn.example.com/project --stdlayout

Make your git repository ignore everything the subversion repo does:

git svn show-ignore >> .git/info/exclude

You should now be able to see all the Subversion branches on the git side:

git branch -r

Say the name of the branch in Subversion is waldo. On the git side, you'd run

git checkout -b waldo-svn remotes/waldo

The -svn suffix is to avoid warnings of the form

warning: refname 'waldo' is ambiguous.

To update the git branch waldo-svn, run

git checkout waldo-svn
git svn rebase

Starting from a trunk-only checkout

To add a Subversion branch to a trunk-only clone, modify your git repository's .git/config to contain

[svn-remote "svn-mybranch"]
        url = http://svn.example.com/project/branches/mybranch
        fetch = :refs/remotes/mybranch

You'll need to develop the habit of running

git svn fetch --fetch-all

to update all of what git svn thinks are separate remotes. At this point, you can create and track branches as above. For example, to create a git branch that corresponds to mybranch, run

git checkout -b mybranch-svn remotes/mybranch

For the branches from which you intend to git svn dcommit, keep their histories linear!

Further information

You may also be interested in reading an answer to a related question.

You need to add a directive, like this:

Javascript:

app.directive('myEnter', function () {
    return function (scope, element, attrs) {
        element.bind("keydown keypress", function (event) {
            if(event.which === 13) {
                scope.$apply(function (){
                    scope.$eval(attrs.myEnter);
                });

                event.preventDefault();
            }
        });
    };
});

HTML:

<div ng-app="" ng-controller="MainCtrl">
    <input type="text" my-enter="doSomething()">    
</div>

request.getSession() or request.getSession(true) both will return a current session only . if current session will not exist then it will create a new session.

All file on all same folder

I managed to figure it out in the end, so if anyone is looking for the answer:

 //Firefox
 $('#elem').bind('DOMMouseScroll', function(e){
     if(e.originalEvent.detail > 0) {
         //scroll down
         console.log('Down');
     }else {
         //scroll up
         console.log('Up');
     }

     //prevent page fom scrolling
     return false;
 });

 //IE, Opera, Safari
 $('#elem').bind('mousewheel', function(e){
     if(e.originalEvent.wheelDelta < 0) {
         //scroll down
         console.log('Down');
     }else {
         //scroll up
         console.log('Up');
     }

     //prevent page fom scrolling
     return false;
 });

You can try it by adding  

Try this:

$("input[name='<%=RadioButtonList1.UniqueID %>']:checked").val()

Use chars:

Dim firstChar As char;
firstChar = s.Chars(0);

http://vb.net-informations.com/string/vb.net_String_Chars.htm

The current code will give a list of all files in a folder, assuming it's on the server side you want to list all files:

var fs = require('fs');
var files = fs.readdirSync('/assets/photos/');

just remenber that 'on' is recomended over the 'bind' function, so always try to use a event listener like this:

$("#myTextBox").on("change paste keyup", function() {
   alert($(this).val()); 
});

I was looking for a way to see if the element is going to come into view soon, so by extending the snippets above i managed to do it. thought i would leave this here just in case it will help someone

elm = is the element you want to check is in the view

scrollElement = you can pass window or a parent element that has a scroll

offset = if you want it to fire when the element is 200px away before its in the screen then pass 200

function isScrolledIntoView(elem, scrollElement, offset)_x000D_
        {_x000D_
            var $elem = $(elem);_x000D_
            var $window = $(scrollElement);_x000D_
            var docViewTop = $window.scrollTop();_x000D_
            var docViewBottom = docViewTop + $window.height();_x000D_
            var elemTop = $elem.offset().top;_x000D_
            var elemBottom = elemTop + $elem.height();_x000D_
            _x000D_

Actually Opera doesn't have 5MB limit. It offers to increase limit as applications requires more. User can even choose "Unlimited storage" for a domain.

You can easily test localStorage limits/quota yourself.

Call this in the project:

svn diff -r REVNO:HEAD --summarize

REVNO is the start revision number and HEAD is the end revision number. If HEAD is equal to the last revision number, it can skip it.

The command returns a list with all files that are changed/added/deleted in this revision period.

The command can be called with the URL revision parameter to check changes like this:

svn diff -r REVNO:HEAD --summarize SVN_URL

this is how i do it with xcode 7.3.1

// create function
func sayhi(){
  print("hello")
}

// create the button

let sayinghi = UIAlertAction(title: "More", style: UIAlertActionStyle.Default, handler:  { action in
            self.sayhi()})

// adding the button to the alert control

myAlert.addAction(sayhi);

// the whole code, this code will add 2 buttons

  @IBAction func sayhi(sender: AnyObject) {
        let myAlert = UIAlertController(title: "Alert", message:"sup", preferredStyle: UIAlertControllerStyle.Alert);
        let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.Default, handler:nil)

        let sayhi = UIAlertAction(title: "say hi", style: UIAlertActionStyle.Default, handler:  { action in
            self.sayhi()})

        // this action can add to more button
        myAlert.addAction(okAction);
        myAlert.addAction(sayhi);

        self.presentViewController(myAlert, animated: true, completion: nil)
    }

    func sayhi(){
        // move to tabbarcontroller
     print("hello")
    }

I have found the problem: Don't use CDN (this is causing the problem!), instead save the jquery file locally on your server and then the problem is away.

For those who are still getting the error even though you added proper keys into Info.plist:

Make sure you are adding the key into correct Info.plist. Newer version of xCode, apparently has 3 Info.plist.

One is under folder with your app's name which solved problem for me.

Second is under YourappnameTests and third one is under YourappnameUITests.

Hope it helps.

To remove newlines, use tr:

tr -d '\n'

If you want to replace each newline with a single space:

tr '\n' ' '

The error ba: Event not found is coming from csh, and is due to csh trying to match !ba in your history list. You can escape the ! and write the command:

sed ':a;N;$\!ba;s/\n/ /g'  # Suitable for csh only!!

but sed is the wrong tool for this, and you would be better off using a shell that handles quoted strings more reasonably. That is, stop using csh and start using bash.

How about using inputStreamReader.ready() to find out?

import java.io.InputStreamReader;

/// ...

InputStreamReader reader = new InputStreamReader(inputStream);
if (reader.ready()) {
    // do something
}

Nuget.exe is placed at .nuget folder of your project. It can't be executed directly in Package Manager Console, but is executed by Powershell commands because these commands build custom path for themselves.

My steps to solve are:

• Download NuGet.exe from https://github.com/NuGet/NuGet.Client/releases (give preference for the latest release);
• Place NuGet.exe in C:\Program Files\NuGet\Visual Studio 2012 (or your VS version);
• Add C:\Program Files\NuGet\Visual Studio 2012 (or your VS version) in PATH environment variable (see http://www.itechtalk.com/thread3595.html as a How-to) (instructions here).
• Close and open Visual Studio.

Update

NuGet can be easily installed in your project using the following command:

Install-Package NuGet.CommandLine

Note that all above answers are correct for Apache+mod-php setups. They're less likely to work with more current PHP-FPM setups. Those can typically only be defined in VirtualHost section, not .htaccess.

Again, this highly depends on how your hoster has configured PHP. Each domain/user will typically have it's own running PHP FPM instance. And subsequently a generic …/x-httpd-php52 type will not be recognized.

See ServerFault: Alias a FastCGI proxy protocol handler via Action/ScriptAlias/etc for some overview.

For Apache 2.4.10+/mod-proxy-fcgi configs you might be able to use something like:

 AddHandler "proxy:unix:/var/run/php-fpm-usr123.sock|fcgi://localhost" .php

Or SetHandler with name mapping from your .htaccess. But again, consulting your hoster on the concrete FPM socket is unavoidable. There's no generic answer to this on modern PHP-FPM setups.

You can add hash info in next page url to move browser at specific position(any html element), after page is loaded.

This is can done in this way:

add hash in the url of next_page : example.com#hashkey

$( document ).ready(function() {

  ##get hash code at next page
  var hashcode = window.location.hash;

  ## move page to any specific position of next page(let that is div with id "hashcode")
  $('html,body').animate({scrollTop: $('div#'+hascode).offset().top},'slow');

});

In my case, the message was caused by a synonym which inadvertently included the database name in the "object name". When I restored the database under a new name, the synonym still pointed to the old DB name. Since the user did not have permissions in the old DB, the message appeared. To fix, I dropped and recreated the synonym without qualifying the object name with the database name:

    USE [new_db]
GO

/****** Object:  Synonym [dbo].[synTable]    Script Date: 10/15/2015 9:45:01 AM ******/
DROP SYNONYM [dbo].[synTable]
GO

/****** Object:  Synonym [dbo].[synTable]    Script Date: 10/15/2015 9:45:01 AM ******/
CREATE SYNONYM [dbo].[synTable] FOR [dbo].[tTheRealTable]
GO

This works for me at runtime too:

UltraPictureBox1.Image = My.Resources.MyPicture

No strings involved and if I change the name it is automatically updated by refactoring.

you can of course solve with a .map as suggested by the other answer. If you already use babel, you could think about using jsx-control-statements They require a little of setting, but I think it's worth in terms of readability (especially for non-react developer). If you use a linter, there's also eslint-plugin-jsx-control-statements

Your interior <div> elements should likely both be float:left. Divs size to 100% the size of their container width automatically. Try using display:inline-block instead of width:auto on the container div. Or possibly float:left the container and also apply overflow:auto. Depends on what you're after exactly.

Another way

writeLines(unlist(lapply(mylist, paste, collapse=" ")))

C# 9 (released with .NET 5) includes the logical patterns and, or and not, which allows us to write this more elegantly:

if (child is not IContainer) { ... }

Likewise, this pattern can be used to check for null:

if (child is not null) { ... }

The top answer works in the case that you want to examine the state immediately prior to the failed command.

However, the question asks how to examine the state of the failed container itself. In my situation, the failed command is a build that takes several hours, so rewinding prior to the failed command and running it again takes a long time and is not very helpful.

The solution here is to find the container that failed:

$ docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                          PORTS               NAMES
6934ada98de6        42e0228751b3        "/bin/sh -c './utils/"   24 minutes ago      Exited (1) About a minute ago                       sleepy_bell

Commit it to an image:

$ docker commit 6934ada98de6
sha256:7015687976a478e0e94b60fa496d319cdf4ec847bcd612aecf869a72336e6b83

And then run the image [if necessary, running bash]:

$ docker run -it 7015687976a4 [bash -il]

Now you are actually looking at the state of the build at the time that it failed, instead of at the time before running the command that caused the failure.

You can use the path module to join the path of the directory in which helper1.js lives to the relative path of foobar.json. This will give you the absolute path to foobar.json.

var fs = require('fs');
var path = require('path');

var jsonPath = path.join(__dirname, '..', 'config', 'dev', 'foobar.json');
var jsonString = fs.readFileSync(jsonPath, 'utf8');

This should work on Linux, OSX, and Windows assuming a UTF8 encoding.

I actually found an extension method that will do what I want nicely

public static IEnumerable<T> ForEach<T>(
    this IEnumerable<T> source,
    Action<T> act)
{
    foreach (T element in source) act(element);
    return source;
}

I was brought here for a reason not explicitly mentioned in the answers so far, so to save others the trouble:

The error also occurs if the function arguments have changed order - for the same reason as in the accepted answer: the positional arguments clash with the keyword arguments.

In my case it was because the argument order of the Pandas set_axis function changed between 0.20 and 0.22:

0.20: DataFrame.set_axis(axis, labels)
0.22: DataFrame.set_axis(labels, axis=0, inplace=None)

Using the commonly found examples for set_axis results in this confusing error, since when you call:

df.set_axis(['a', 'b', 'c'], axis=1)

prior to 0.22, ['a', 'b', 'c'] is assigned to axis because it's the first argument, and then the positional argument provides "multiple values".

Very simple code with Bootstrap and JQuery without any additionnal javascript code :

HTML :

<div class="dropdown">
  <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
    Dropdown button
  </button>
  <form class="dropdown-menu" aria-labelledby="dropdownMenuButton">
    <label class="dropdown-item"><input type="checkbox" name="" value="one">First checkbox</label>
    <label class="dropdown-item"><input type="checkbox" name="" value="two">Second checkbox</label>
    <label class="dropdown-item"><input type="checkbox" name="" value="three">Third checkbox</label>
  </form>
</div>

CSS :

.dropdown-menu label {
  display: block;
}

Why not simply use the submit button to run the code you want. If your function returns false, it will cancel the submission.

$("#testForm").submit(function() {
    /* Do Something */
    return false;
});

Have you tried using an iFrame? No ajax, and the original page will not load.

You can display the submit form as a separate page inside the iframe, and when it gets submitted the outer/container page will not reload. This solution will not make use of any kind of ajax.

This was found on Dragon-IT Scripts and Code Repository.

You can do this with the following and stay away from the cscript/wscript differences and allows you to get the same console output that a batch file would have. This can help if your calling VBS from a batch file and need to make it look seamless.

Set fso = CreateObject ("Scripting.FileSystemObject")
Set stdout = fso.GetStandardStream (1)
Set stderr = fso.GetStandardStream (2)
stdout.WriteLine "This will go to standard output."
stderr.WriteLine "This will go to error output."

If the server is writing the file back in the response (including cookies if you use them to determine whether the file download started), Simply create a form with the values and submit it:

function ajaxPostDownload(url, data) {
    var $form;
    if (($form = $('#download_form')).length === 0) {
        $form = $("<form id='download_form'" + " style='display: none; width: 1px; height: 1px; position: absolute; top: -10000px' method='POST' action='" + url + "'></form>");
        $form.appendTo("body");
    }
    //Clear the form fields
    $form.html("");
    //Create new form fields
    Object.keys(data).forEach(function (key) {
        $form.append("<input type='hidden' name='" + key + "' value='" + data[key] + "'>");
    });
    //Submit the form post
    $form.submit();
}

Usage:

ajaxPostDownload('/fileController/ExportFile', {
    DownloadToken: 'newDownloadToken',
    Name: $txtName.val(),
    Type: $txtType.val()
});

Controller Method:

[HttpPost]
public FileResult ExportFile(string DownloadToken, string Name, string Type)
{
    //Set DownloadToken Cookie.
    Response.SetCookie(new HttpCookie("downloadToken", DownloadToken)
    {
        Expires = DateTime.UtcNow.AddDays(1),
        Secure = false
    });

    using (var output = new MemoryStream())
    {
        //get File
        return File(output.ToArray(), "application/vnd.ms-excel", "NewFile.xls");
    }
}

Find *.pem file and place it to the anchors sub-directory or just simply link the *.pem file to there.

yum install -y ca-certificates
update-ca-trust force-enable
sudo ln -s /etc/ssl/your-cert.pem /etc/pki/ca-trust/source/anchors/your-cert.pem
update-ca-trust

This is more robust:

mi = location.href.split(/(\d+)/);
no = mi.length - 2;
os = mi[no];
mi[no]++;
if ((mi[no] + '').length < os.length) mi[no] = os.match(/0+/) + mi[no];
location.href = mi.join('');

When the URL has multiple numbers, it will change the last one:

http://mywebsite.com/8815/1.html

It supports numbers with leading zeros:

http://mywebsite.com/0001.html

Example

Besides just using include() or include_once() to include the header and footer, one thing I have found useful is being able to have a custom page title or custom head tags to be included for each page, yet still have the header in a partial include. I usually accomplish this as follows:

In the site pages:

<?php

$PageTitle="New Page Title";

function customPageHeader(){?>
  <!--Arbitrary HTML Tags-->
<?php }

include_once('header.php');

//body contents go here

include_once('footer.php');
?>

And, in the header.php file:

<!doctype html>
<html>
  <head>
    <meta http-equiv="content-type" content="text/html; charset=UTF-8">
    <title><?= isset($PageTitle) ? $PageTitle : "Default Title"?></title>
    <!-- Additional tags here -->
    <?php if (function_exists('customPageHeader')){
      customPageHeader();
    }?>
  </head>
  <body>

Maybe a bit beyond the scope of your original question, but it is useful to allow a bit more flexibility with the include.

What if you don't want to commit every commit that you make in Git, to the SVN repository? What if you just want to selectively send commits up the pipe? Well, I have a better solution.

I keep one local Git repository where all I ever do is fetch and merge from SVN. That way I can make sure I'm including all the same changes as SVN, but I keep my commit history separate from the SVN entirely.

Then I keep a separate SVN local working copy that is in a separate folder. That's the one I make commits back to SVN from, and I simply use the SVN command line utility for that.

When I'm ready to commit my local Git repository's state to SVN, I simply copy the whole mess of files over into the local SVN working copy and commit it from there using SVN rather than Git.

This way I never have to do any rebasing, because rebasing is like freebasing.
