It affects at least NetBeans versions 7.4 through 8.0.2. It was first reported from version 8.0 and fixed in NetBeans 8.1. It would have had the problem for any tomcat version (confirmed for versions 7.0.56 through 8.0.28).

Specifics are described as Netbeans bug #248182.

This problem is also related to postings mentioning the following error output:

'127.0.0.1*' is not recognized as an internal or external command, operable program or batch file.

For a tomcat installed from the zip file, I fixed it by changing the catalina.bat file in the tomcat bin directory.

Find the bellow configuration in your catalina.bat file.

:noJuliConfig
set "JAVA_OPTS=%JAVA_OPTS% %LOGGING_CONFIG%"

:noJuliManager
set "JAVA_OPTS=%JAVA_OPTS% %LOGGING_MANAGER%"

And change it as in below by removing the double quotes:

:noJuliConfig
set JAVA_OPTS=%JAVA_OPTS% %LOGGING_CONFIG%

:noJuliManager
set JAVA_OPTS=%JAVA_OPTS% %LOGGING_MANAGER%

Now save your changes, and start your tomcat from within NetBeans.

The only thing the eclipse plugin is checking is the tomcat version inside:

catalina.jar!/org/apache/catalina/util/ServerInfo.properties

I replaced the properties file with the one in tomcat7 and that fixed the issue for eclipse

In order to be able to deploy the spring-websockets sample app you need to edit the following file in eclipse:

.settings/org.eclipse.wst.common.project.facet.core.xml

And change the web version to 2.5

<installed facet="jst.web" version="2.5"/>

bw.newLine(); cannot ensure compatibility with all systems.

If you are sure it is going to be opened in windows, you can format it to windows newline.

If you are already using native unix commands, try unix2dos and convert teh already generated file to windows format and then send the mail.

If you are not using unix commands and prefer to do it in java, use ``bw.write("\r\n")` and if it does not complicate your program, have a method that finds out the operating system and writes the appropriate newline.

how about this?

([0-9]{1,3}\.){3}[0-9]{1,3}

In my sample code, I was setting my object to nothing, and I couldn't get the "not" part of the if statement to work with the object. I tried if My_Object is not nothing and also if not My_Object is nothing. It may be just a syntax thing I can't figure out but I didn't have time to mess around, so I did a little workaround like this:

if My_Object is Nothing Then
    'do nothing
Else
    'Do something
End if

I was setting the bearer token

httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);

It was working in one endpoint, but not another. The issue was that I had lower case b on "bearer". After change now it works for both api's I'm hitting. Such an easy thing to miss if you aren't even considering it as one of the haystacks to look in for the needle.

Make sure to have "Bearer" - with capital.

you can also have two classes within an element like this

<div class = "item1 item2 item3"></div

I can't see the value of this, since by the principle of cascading styles, the last one takes precedence. For example, if in my earlier example I changed the HTML to read

 <div class="box1 box2"> Hello what is my color? </div>

the box's border and text would be blue, since .box2's style assigns these values.

Also in my earlier post I should have emphasized that adding selectors as I did is not the same as creating a subclass within a class (the first solution in this thread), though the effect is similar.

I also ran into the same problem, where the initial dtabase size is set to 4Gb and autogrowth is set by 1Mb. The virtual encrypted TrueCrypt drive that the databse was on, seemed to have plenty of space.

I changed a couple of (the above) things:

• I turned the Windows service for Sql Server Express from automatic to manual, so only the 'regular' Sql Server is running. (Even though I am running Sql Server 2008 R2 which should allow 10 GB.)
• I changed the autogrowth from 1 MB to 10%
• I changed the autogrowth increment-size from 10% to 1000 MB
• I defragmented the drive
• I shrank the database:
  • manually DBCC SHRINKDATABASE('...')
  • automatically right click on database | "properties" | "Auto Shrink" | "Truncate log on check point")

All to little avail (I could insert some more records, but soon ran into the same problem). The pagefile mentioned by Tobbi, made me try a larger virtual drive. (Even though my drive should not contain any such system files, since I run without it being mounted a lot of the time.)

• I made a new larger virtual drive with TrueCrypt

When making this, I ran into a TrueCrypt-question, if I am going to store files larger than 4gb (as shown in this SuperUser question).

• I told TrueCrypt I would store files larger than 4 GB

After these last two I was doing fine, and I am assuming this last one did the trick. I think TrueCrypt chooses an exfat file system (as described here), which limits all files to 4GB. (So I probably did not need to enlarge the drive after all, but I did anyway.)

This is probably a very rare border case, but maybe it is of help to somebody.

You're not saying how exactly putdata() is not behaving. I'm assuming you're doing

>>> pic.putdata(a)
Traceback (most recent call last):
  File "...blablabla.../PIL/Image.py", line 1185, in putdata
    self.im.putdata(data, scale, offset)
SystemError: new style getargs format but argument is not a tuple

This is because putdata expects a sequence of tuples and you're giving it a numpy array. This

>>> data = list(tuple(pixel) for pixel in pix)
>>> pic.putdata(data)

will work but it is very slow.

As of PIL 1.1.6, the "proper" way to convert between images and numpy arrays is simply

>>> pix = numpy.array(pic)

although the resulting array is in a different format than yours (3-d array or rows/columns/rgb in this case).

Then, after you make your changes to the array, you should be able to do either pic.putdata(pix) or create a new image with Image.fromarray(pix).

Working Solution :

For Resize image with size lower then 100Kb

WriteableBitmap bitmap = new WriteableBitmap(140,140);
bitmap.SetSource(dlg.File.OpenRead());
image1.Source = bitmap;

Image img = new Image();
img.Source = bitmap;
WriteableBitmap i;

do
{
    ScaleTransform st = new ScaleTransform();
    st.ScaleX = 0.3;
    st.ScaleY = 0.3;
    i = new WriteableBitmap(img, st);
    img.Source = i;
} while (i.Pixels.Length / 1024 > 100);

For PowerShell 3.0 and later, there is one built in :)

foreach ($item in $array) {
    $array.IndexOf($item)
}

or is not exclusive (e.g. xor) so or is the same thing as and/or.

Just for reference as it was something I was looking for, you can test for presence within the values or the index by appending the ".values" method, e.g.

g in df.<your selected field>.values
g in df.index.values

I find that adding the ".values" to get a simple list or ndarray out makes exist or "in" checks run more smoothly with the other python tools. Just thought I'd toss that out there for people.

So I assume your permissions table has a foreign key reference to admin_accounts table. If so because of referential integrity you will only be able to add permissions for account ids exsiting in the admin accounts table. Which also means that you wont be able to enter a user_account_id [assuming there are no duplicates!]

jQuery is just JavaScript, don't think very differently about it! Like you would do in 'normal' JS, you add an event listener to the buttons and change the action attribute of the form. In jQuery this looks something like:

$('#button1').click(function(){
   $('#your_form').attr('action', 'http://uri-for-button1.com');
});

This code is the same for the second button, you only need to change the id of your button and the URI where the form should be submitted to.

There are plenty of good answers given here for loading controllers within controllers, but for me, this contradicts the mvc pattern.

The sentence that worries me is;

(filled with data processed by the product controller)

The models are there for processing and returning data. If you put this logic into your product model then you can call it from any controller you like without having to try to pervert the framework.

Once of the most helpful quotes I read was that the controller was like the 'traffic cop', there to route requests and responses between models and views.

The faster way for your case is:

    jTable.repaint(); // Repaint all the component (all Cells).

The optimized way when one or few cell change:

    ((AbstractTableModel) jTable.getModel()).fireTableCellUpdated(x, 0); // Repaint one cell.

Just the same way as you would do in normal Java code.

for (Map.Entry<String, String> entry : countries.entrySet()) {
    String key = entry.getKey();
    String value = entry.getValue();
    // ...
}

However, scriptlets (raw Java code in JSP files, those <% %> things) are considered a poor practice. I recommend to install JSTL (just drop the JAR file in /WEB-INF/lib and declare the needed taglibs in top of JSP). It has a <c:forEach> tag which can iterate over among others Maps. Every iteration will give you a Map.Entry back which in turn has getKey() and getValue() methods.

Here's a basic example:

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

<c:forEach items="${map}" var="entry">
    Key = ${entry.key}, value = ${entry.value}<br>
</c:forEach>

Thus your particular issue can be solved as follows:

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

<select name="country">
    <c:forEach items="${countries}" var="country">
        <option value="${country.key}">${country.value}</option>
    </c:forEach>
</select>

You need a Servlet or a ServletContextListener to place the ${countries} in the desired scope. If this list is supposed to be request-based, then use the Servlet's doGet():

protected void doGet(HttpServletRequest request, HttpServletResponse response) {
    Map<String, String> countries = MainUtils.getCountries();
    request.setAttribute("countries", countries);
    request.getRequestDispatcher("/WEB-INF/page.jsp").forward(request, response);
}

Or if this list is supposed to be an application-wide constant, then use ServletContextListener's contextInitialized() so that it will be loaded only once and kept in memory:

public void contextInitialized(ServletContextEvent event) {
    Map<String, String> countries = MainUtils.getCountries();
    event.getServletContext().setAttribute("countries", countries);
}

In both cases the countries will be available in EL by ${countries}.

Hope this helps.

First, check the path you get with which emulator and if you get /usr/local/share/android-sdk/tools/emulator then remove or rename that emulator (it's an old one) and instead use /usr/local/share/android-sdk/emulator/emulator which is the new path.

If you're using Homebrew and installed with brew cask install android-sdk android-studio then you need to:

1. Verify your .bashrc or .zshrc that you have the correct paths set:

# Remove $HOME/Library/Android paths
# The new way is to use ANDROID_SDK_ROOT
export ANDROID_SDK_ROOT="/usr/local/share/android-sdk"
# For good measure, add old paths to be backwards compatible with any scripts or 
whatnot. And to hopefully decrease confusion:
export ANDROID_HOME=$ANDROID_SDK_ROOT
export ANDROID_NDK_HOME=$ANDROID_SDK_ROOT/ndk-bundle

2. Then restart your terminal shell, and check your paths are as you expect them:

   set | grep ANDROID

3. Finally, with correct paths set, you typically need to install the ndk and some tools:

   sdkmanager "ndk-bundle" "cmake;3.10.2.4988404" "lldb;3.1"

   and check the list for other pieces like this sdkmanager --list

I also closed Android Studio, removed the old Android/Sdk folder under my $HOME folder, and restarted Studio, and when it asked where my Sdk had gone, I pasted the Sdk path: /usr/local/share/android-sdk

I did this for a <div> on Chrome.

element.scrollTop - is the pixels hidden in top due to the scroll. With no scroll its value is 0.

element.scrollHeight - is the pixels of the whole div.

element.clientHeight - is the pixels that you see in your browser.

var a = element.scrollTop;

will be the position.

var b = element.scrollHeight - element.clientHeight;

will be the maximum value for scrollTop.

var c = a / b;

will be the percent of scroll [from 0 to 1].

Here is a good example of base64 encoding byte arrays. It gets more complicated when you throw unicode characters in the mix to send things like PDF documents. After encoding a byte array the encoded string can be used as a JSON property value.

Apache commons offers good utilities:

 byte[] bytes = getByteArr();
 String base64String = Base64.encodeBase64String(bytes);
 byte[] backToBytes = Base64.decodeBase64(base64String);

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Base64_encoding_and_decoding

Java server side example:

public String getUnsecureContentBase64(String url)
        throws ClientProtocolException, IOException {

            //getUnsecureContent will generate some byte[]
    byte[] result = getUnsecureContent(url);

            // use apache org.apache.commons.codec.binary.Base64
            // if you're sending back as a http request result you may have to
            // org.apache.commons.httpclient.util.URIUtil.encodeQuery
    return Base64.encodeBase64String(result);
}

JavaScript decode:

//decode URL encoding if encoded before returning result
var uriEncodedString = decodeURIComponent(response);

var byteArr = base64DecToArr(uriEncodedString);

//from mozilla
function b64ToUint6 (nChr) {

  return nChr > 64 && nChr < 91 ?
      nChr - 65
    : nChr > 96 && nChr < 123 ?
      nChr - 71
    : nChr > 47 && nChr < 58 ?
      nChr + 4
    : nChr === 43 ?
      62
    : nChr === 47 ?
      63
    :
      0;

}

function base64DecToArr (sBase64, nBlocksSize) {

  var
    sB64Enc = sBase64.replace(/[^A-Za-z0-9\+\/]/g, ""), nInLen = sB64Enc.length,
    nOutLen = nBlocksSize ? Math.ceil((nInLen * 3 + 1 >> 2) / nBlocksSize) * nBlocksSize : nInLen * 3 + 1 >> 2, taBytes = new Uint8Array(nOutLen);

  for (var nMod3, nMod4, nUint24 = 0, nOutIdx = 0, nInIdx = 0; nInIdx < nInLen; nInIdx++) {
    nMod4 = nInIdx & 3;
    nUint24 |= b64ToUint6(sB64Enc.charCodeAt(nInIdx)) << 18 - 6 * nMod4;
    if (nMod4 === 3 || nInLen - nInIdx === 1) {
      for (nMod3 = 0; nMod3 < 3 && nOutIdx < nOutLen; nMod3++, nOutIdx++) {
        taBytes[nOutIdx] = nUint24 >>> (16 >>> nMod3 & 24) & 255;
      }
      nUint24 = 0;

    }
  }

  return taBytes;
}

InputType on the textfield must be text in order for what CommonsWare said to work. Just tried all of this, no inputType before the trial and nothing worked, Enter kept registering as soft enter. After inputType = text, everything including the setImeLabel worked.

Example : android:inputType="text"

Use FLOOR:

SELECT FLOOR(your_field) FROM your_table

Normal text editors are nano, or vi.

For example:

root@user:# nano galfit.feedme

or

root@user:# vi galfit.feedme

Dispose(true);
GC.SuppressFinalize(this);

If object has finalizer, .net put a reference in finalization queue.

Since we have call Dispose(ture), it clear object, so we don't need finalization queue to do this job.

So call GC.SuppressFinalize(this) remove reference in finalization queue.

Feb 3rd 2020:

• Atlassian Bitbucket v5.8.3 local installation.
• I wanted to add a new line around an horizontal line. --- did produce the line, but I could not get new lines to work with suggestions above.
• note: I did not want to use the [space][space] suggestion, since my editor removes trailing spaces on save, and I like this feature on.

I ended up doing this:

TEXT...

TEXT...

Resulting in:

TEXT...
<AN EMPTY LINE>
----------------- AN HORIZONTAL LINE ----------------
<AN EMPTY LINE>
TEXT...

In python, the str() method is similar to the toString() method in other languages. It is called passing the object to convert to a string as a parameter. Internally it calls the __str__() method of the parameter object to get its string representation.

In this case, however, you are comparing a UserProperty author from the database, which is of type users.User with the nickname string. You will want to compare the nickname property of the author instead with todo.author.nickname in your template.

you can use just javascript for it

var total =10.8
(total).toFixed(2); 10.80


alert(total.toFixed(2))); 

With Homebrew installed:

brew install watch

Symfony 2.2

this solution is deprecated since 2.3 and will be removed in 3.0, see documentation

$form->getData();

gives you an array for the form parameters

from symfony2 book page 162 (Chapter 12: Forms)

[...] sometimes, you may just want to use a form without a class, and get back an array of the submitted data. This is actually really easy:

public function contactAction(Request $request) {
  $defaultData = array('message' => 'Type your message here');
  $form = $this->createFormBuilder($defaultData)
  ->add('name', 'text')
  ->add('email', 'email')
  ->add('message', 'textarea')
  ->getForm();
  if ($request->getMethod() == 'POST') {
    $form->bindRequest($request);
    // data is an array with "name", "email", and "message" keys
    $data = $form->getData();
  }
  // ... render the form
}

You can also access POST values (in this case "name") directly through the request object, like so:

$this->get('request')->request->get('name');

Be advised, however, that in most cases using the getData() method is a better choice, since it returns the data (usually an object) after it's been transformed by the form framework.

When you want to access the form token, you have to use the answer of Problematic $postData = $request->request->get('contact'); because the getData() removes the element from the array

Symfony 2.3

since 2.3 you should use handleRequest instead of bindRequest:

 $form->handleRequest($request);

see documentation

I have had the same problem. And it was hard to find. But somewhere in my code was this:

- (NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    return nil;
}

It must be return indexPath, else -tableView:didSelectRowAtIndexPath: is not being called.

I have had this issue, and I use the following :

ls -dl $PWD/* | grep $PWD

It has always got me the listingI have wanted, but your mileage may vary.

How about alias gcc99= gcc -std=c99?

I had this problem with bundles having incorrect path's to images and CssRewriteUrlTransform not resolving relative parent paths .. correctly (there was also problem with external resources like webfonts). That's why I wrote this custom transform (appears to do all of the above correctly):

public class CssRewriteUrlTransform2 : IItemTransform
{
    public string Process(string includedVirtualPath, string input)
    {
        var pathParts = includedVirtualPath.Replace("~/", "/").Split('/');
        pathParts = pathParts.Take(pathParts.Count() - 1).ToArray();
        return Regex.Replace
        (
            input,
            @"(url\(['""]?)((?:\/??\.\.)*)(.*?)(['""]?\))",
            m => 
            {
                // Somehow assigning this to a variable is faster than directly returning the output
                var output =
                (
                    // Check if it's an aboslute url or base64
                    m.Groups[3].Value.IndexOf(':') == -1 ?
                    (
                        m.Groups[1].Value +
                        (
                            (
                                (
                                    m.Groups[2].Value.Length > 0 ||
                                    !m.Groups[3].Value.StartsWith('/')
                                )
                            ) ?
                            string.Join("/", pathParts.Take(pathParts.Count() - m.Groups[2].Value.Count(".."))) :
                            ""
                        ) +
                        (!m.Groups[3].Value.StartsWith('/') ? "/" + m.Groups[3].Value : m.Groups[3].Value) +
                        m.Groups[4].Value
                    ) :
                    m.Groups[0].Value
                );
                return output;
            }
        );
    }
}

Edit: I didn't realize it, but I used some custom extension methods in the code. The source code of those is:

/// <summary>
/// Based on: http://stackoverflow.com/a/11773674
/// </summary>
public static int Count(this string source, string substring)
{
    int count = 0, n = 0;

    while ((n = source.IndexOf(substring, n, StringComparison.InvariantCulture)) != -1)
    {
        n += substring.Length;
        ++count;
    }
    return count;
}

public static bool StartsWith(this string source, char value)
{
    if (source.Length == 0)
    {
        return false;
    }
    return source[0] == value;
}

Of course it should be possible to replace String.StartsWith(char) with String.StartsWith(string).

If you using JavaScript to test your Regex, try \\. instead of \..

It acts on the same way because JS remove first backslash.

This works for modern browsers (2016 at time of edit) as shown in this demo on codepen

.frame {
    height: 25px;
    line-height: 25px;
    width: 160px;
    border: 1px solid #83A7D3;          
}
.frame img {
    background: #3A6F9A;
    display:inline-block;
    vertical-align: middle;
}

It is very important that you either give the images a class or use inheritance to target the images that you need centered. In this example we used .frame img {} so that only images wrapped by a div with a class of .frame would be targeted.

driver.Manage().Window.Maximize();

This works for IE and Firefox. Chrome does not work. There is a bug submitted for this on ChromeDriver project.

Meanwhile, the get around for the chrome is to implement what Joey V. and Coder323 suggested.

ChromeOptions options = new ChromeOptions();
options.addArgument("--start-maximized");
driver = new ChromeDriver(options);

I found this from my friend, very effective if you are looking for all the table's primary keys under particular schema.

SELECT tc.constraint_name AS IndexName,tc.table_name AS TableName,tc.table_schema
AS SchemaName,kc.column_name AS COLUMN_NAME
FROM information_schema.table_constraints tc,information_schema.key_column_usage kc
WHERE tc.constraint_type = 'PRIMARY KEY' AND kc.table_name = tc.table_name AND kc.table_schema = tc.table_schema
AND kc.constraint_name = tc.constraint_name AND tc.table_schema='<SCHEMA_NAME>'

This is a very interesting bug. (In my opinion, it is a bug anyway) Nice find!

Regarding how to set it, I would recommend Camilo Martin's answer. But as to why, I'd like to explain this a bit if you guys don't mind.

In the CSS specs I found:

'padding'
Percentages: refer to width of containing block

… which is weird, but okay.

So, with a parent width: 210px and a child padding-top: 50%, I get a calculated/computed value of padding-top: 96.5px – which is not the expected 105px.

That is because in Windows (I'm not sure about other OSs), the size of common scrollbars is per default 17px × 100% (or 100% × 17px for horizontal bars). Those 17px are substracted before calculating the 50%, hence 50% of 193px = 96.5px.

What do you mean by converting?

• casting*: (int) $float or intval($float)
• truncating: floor($float) (down) or ceil($float) (up)
• rounding: round($float) - has additional modes, see PHP_ROUND_HALF_... constants

*: casting has some chance, that float values cannot be represented in int (too big, or too small), f.ex. in your case.

PHP_INT_MAX: The largest integer supported in this build of PHP. Usually int(2147483647).

But, you could use the BCMath, or the GMP extensions for handling these large numbers. (Both are boundled, you only need to enable these extensions)

I finally figured out the regex to change these all in old Python2 example scripts. Otherwise use 2to3.py.

Try it out on Regexr.com, doesn't work in NP++(?):

find:     (?<=print)( ')(.*)(')
replace: ('$2')

for variables:

(?<=print)( )(.*)(\n)
('$2')\n

for label and variable:

(?<=print)( ')(.*)(',)(.*)(\n)
('$2',$4)\n

A weak entity is one that can only exist when owned by another one. For example: a ROOM can only exist in a BUILDING. On the other hand, a TIRE might be considered as a strong entity because it also can exist without being attached to a CAR.

According to fresh Quirksmode the clientX and clientY methods are supported in all major browsers. So, here it goes - the good, working code that works in a scrolling div on a page with scrollbars:

function getCursorPosition(canvas, event) {
var x, y;

canoffset = $(canvas).offset();
x = event.clientX + document.body.scrollLeft + document.documentElement.scrollLeft - Math.floor(canoffset.left);
y = event.clientY + document.body.scrollTop + document.documentElement.scrollTop - Math.floor(canoffset.top) + 1;

return [x,y];
}

This also requires jQuery for $(canvas).offset().

You can call private methods.

If you encountered the following error:

expect(new FooBar(/*...*/).initFooBar()).toEqual(/*...*/);
// TS2341: Property 'initFooBar' is private and only accessible within class 'FooBar'

just use // @ts-ignore:

// @ts-ignore
expect(new FooBar(/*...*/).initFooBar()).toEqual(/*...*/);

A browser isn't going to show you white space reliably. I recommend the Linux 'od' command to see what's really in there. Comforming XML parsers will respect all of the methods you listed.

I realize this is an old question, but it took me several hours to find a good solution and thought I'd pass on what I learned here and save someone else the trouble. Try, for example,

SELECT * FROM some_table WHERE id_column = ANY(@id_list)

where @id_list is bound to an int[] parameter by way of

command.Parameters.Add("@id_list", NpgsqlDbType.Array | NpgsqlDbType.Integer).Value = my_id_list;

where command is a NpgsqlCommand (using C# and Npgsql in Visual Studio).

Here is how to set it correctly for both iOS 6 and 7.

+ (void)fixNavBarColor:(UINavigationBar*)bar {
    if (iosVersion >= 7) {
        bar.barTintColor = [UIColor redColor];
        bar.translucent = NO;
    }else {
        bar.tintColor = [UIColor redColor];
        bar.opaque = YES;
    }
}

Just read the docs:

This exception is thrown when no initial context implementation can be created. The policy of how an initial context implementation is selected is described in the documentation of the InitialContext class.

This exception can be thrown during any interaction with the InitialContext, not only when the InitialContext is constructed. For example, the implementation of the initial context might lazily retrieve the context only when actual methods are invoked on it. The application should not have any dependency on when the existence of an initial context is determined.

But this is explained much better in the docs for InitialContext

PM2 now supports npm start:

pm2 start npm -- start

To assign a name to the PM2 process, use the --name option:

pm2 start npm --name "app name" -- start

To get the n most frequent values, just subset .value_counts() and grab the index:

# get top 10 most frequent names
n = 10
dataframe['name'].value_counts()[:n].index.tolist()

If you do not want your application to terminate when a JFrame is closed, use: setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE)

instead of: setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

From the documentation:

DO_NOTHING_ON_CLOSE (defined in WindowConstants): Don't do anything; require the program to handle the operation in the windowClosing method of a registered WindowListener object.

HIDE_ON_CLOSE (defined in WindowConstants): Automatically hide the frame after invoking any registered WindowListener objects.

DISPOSE_ON_CLOSE (defined in WindowConstants): Automatically hide and dispose the frame after invoking any registered WindowListener objects.

EXIT_ON_CLOSE (defined in JFrame): Exit the application using the System exit method. Use this only in applications.

might still be useful: You can use setVisible(false) on your JFrame if you want to display the same frame again. Otherwise call dispose() to remove all of the native screen resources.

Using .trigger("chosen:updated"); you can update the options list after appending.

Updating Chosen Dynamically: If you need to update the options in your select field and want Chosen to pick up the changes, you'll need to trigger the "chosen:updated" event on the field. Chosen will re-build itself based on the updated content.

Your code:

$("#refreshgallery").click(function(){
        $('#picturegallery').empty(); //remove all child nodes
        var newOption = $('<option value="1">test</option>');
        $('#picturegallery').append(newOption);
        $('#picturegallery').trigger("chosen:updated");
    });

I'm pretty sure you can't simply add on delete cascade to an existing foreign key constraint. You have to drop the constraint first, then add the correct version. In standard SQL, I believe the easiest way to do this is to

• start a transaction,
• drop the foreign key,
• add a foreign key with on delete cascade, and finally
• commit the transaction

Repeat for each foreign key you want to change.

But PostgreSQL has a non-standard extension that lets you use multiple constraint clauses in a single SQL statement. For example

alter table public.scores
drop constraint scores_gid_fkey,
add constraint scores_gid_fkey
   foreign key (gid)
   references games(gid)
   on delete cascade;

If you don't know the name of the foreign key constraint you want to drop, you can either look it up in pgAdminIII (just click the table name and look at the DDL, or expand the hierarchy until you see "Constraints"), or you can query the information schema.

select *
from information_schema.key_column_usage
where position_in_unique_constraint is not null

• The simple Solution is just uninstall the javaSE and reinstall it to the default location.

• Then copy the installed location probably like C:\Program Files\Java\jdk1.8.0_131\bin.

• After then go to desktop then while selecting right click on My Pc or This pc shortcut the under that select properties >> Advanced system settings >> under Advance tab >> last option Environment Variables..>>path >> edit >> past >> ;(not required if win10)/(required if windows 7)

I had to delete the bin and obj folders from each folder in order to resolve this.

It is important to recognize that the copyright laws have changed and that for non-US sources, especially after the USA joining the Berne Convention on March 1, 1989, copyright registration in not necessary for enforcement of a copyright notice.
Here is a resumé quoted from the Cornell University Law School (copied on March 4, 2015 from https://www.law.cornell.edu/wex/copyright:

"Copyright copyright: an overview

The U.S. Copyright Act, 17 U.S.C. §§ 101 - 810, is Federal legislation enacted by Congress under its Constitutional grant of authority to protect the writings of authors. See U.S. Constitution, Article I, Section 8. Changing technology has led to an ever expanding understanding of the word "writings." The Copyright Act now reaches architectural design, software, the graphic arts, motion pictures, and sound recordings. See § 106. As of January 1, 1978, all works of authorship fixed in a tangible medium of expression and within the subject matter of copyright were deemed to fall within the exclusive jurisdiction of the Copyright Act regardless of whether the work was created before or after that date and whether published or unpublished. See § 301. See also preemption.

The owner of a copyright has the exclusive right to reproduce, distribute, perform, display, license, and to prepare derivative works based on the copyrighted work. See § 106. The exclusive rights of the copyright owner are subject to limitation by the doctrine of "fair use." See § 107. Fair use of a copyrighted work for purposes such as criticism, comment, news reporting, teaching, scholarship, or research is not copyright infringement. To determine whether or not a particular use qualifies as fair use, courts apply a multi-factor balancing test. See § 107.

Copyright protection subsists in original works of authorship fixed in any tangible medium of expression from which they can be perceived, reproduced, or otherwise communicated, either directly or with the aid of a machine or device. See § 102. Copyright protection does not extend to any idea, procedure, process, system, method of operation, concept, principle, or discovery. For example, if a book is written describing a new system of bookkeeping, copyright protection only extends to the author's description of the bookkeeping system; it does not protect the system itself. See Baker v. Selden, 101 U.S. 99 (1879).

According to the Copyright Act of 1976, registration of copyright is voluntary and may take place at any time during the term of protection. See § 408. Although registration of a work with the Copyright Office is not a precondition for protection, an action for copyright infringement may not be commenced until the copyright has been formally registered with the Copyright Office. See § 411.

Deposit of copies with the Copyright Office for use by the Library of Congress is a separate requirement from registration. Failure to comply with the deposit requirement within three months of publication of the protected work may result in a civil fine. See § 407. The Register of Copyrights may exempt certain categories of material from the deposit requirement.

In 1989 the U.S. joined the Berne Convention for the Protection of Literary and Artistic Works. In accordance with the requirements of the Berne Convention, notice is no longer a condition of protection for works published after March 1, 1989. This change to the notice requirement applies only prospectively to copies of works publicly distributed after March 1, 1989.

The Berne Convention also modified the rule making copyright registration a precondition to commencing a lawsuit for infringement. For works originating from a Berne Convention country, an infringement action may be initiated without registering the work with the U.S. Copyright Office. However, for works of U.S. origin, registration prior to filing suit is still required.

The federal agency charged with administering the act is the Copyright Office of the Library of Congress. See § 701 of the act. Its regulations are found in Parts 201 - 204 of title 37 of the Code of Federal Regulations."

You can also use the interface builder to create these effects easily for simple situations. Since the z-values of the views will depend on the order they are listed in the Document Outline, you can drag a UIVisualEffectView onto the document outline before the view you want to blur. This automatically creates a nested UIView, which is the contentView property of the given UIVisualEffectView. Nest things within this view that you want to appear on top of the blur.

You can also easily take advantage of the vibrancy UIVisualEffect, which will automatically create another nested UIVisualEffectView in the document outline with vibrancy enabled by default. You can then add a label or text view to the nested UIView (again, the contentView property of the UIVisualEffectView), to achieve the same effect that the "> slide to unlock" UI element.

Note here i am using custom cell this code is perfectly working for me

 @IBAction func call(sender: UIButton)
    {
        var contentView = sender.superview;
        var cell = contentView?.superview as EmployeeListCustomCell
        if (!(cell.isKindOfClass(EmployeeListCustomCell)))
        {
            cell = (contentView?.superview)?.superview as EmployeeListCustomCell
        }

        let phone = cell.lblDescriptionText.text!
        //let phone = detailObject!.mobile!
        let url:NSURL = NSURL(string:"tel://"+phone)!;
        UIApplication.sharedApplication().openURL(url);
    }

word-wrap: break-word

But it's CSS3 - http://www.css3.com/css-word-wrap/.

That's pretty easy:

class Sample {
    private String message = null;
    private final Object lock = new Object();

    public void newMessage(String x) {
        synchronized (lock) {
            message = x;
        }
    }

    public String getMessage() {
        synchronized (lock) {
            String temp = message;
            message = null;
            return temp;
        }
    }
}

Note that I didn't either make the methods themselves synchronized or synchronize on this. I firmly believe that it's a good idea to only acquire locks on objects which only your code has access to, unless you're deliberately exposing the lock. It makes it a lot easier to reassure yourself that nothing else is going to acquire locks in a different order to your code, etc.

I had this issue too, also running on an emulator.. The same message was showing up on Logcat, but it wasn't affecting the functionality of the app. But it was annoying, and I don't like seeing errors on the log that I don't understand.

Anyway, I got rid of the message by increasing the RAM on the emulator.

You can cast your JToken to a JObject and then use the Properties() method to get a list of the object properties. From there, you can get the names rather easily.

Something like this:

string json =
@"{
    ""ADDRESS_MAP"":{

        ""ADDRESS_LOCATION"":{
            ""type"":""separator"",
            ""name"":""Address"",
            ""value"":"""",
            ""FieldID"":40
        },
        ""LOCATION"":{
            ""type"":""locations"",
            ""name"":""Location"",
            ""keyword"":{
                ""1"":""LOCATION1""
            },
            ""value"":{
                ""1"":""United States""
            },
            ""FieldID"":41
        },
        ""FLOOR_NUMBER"":{
            ""type"":""number"",
            ""name"":""Floor Number"",
            ""value"":""0"",
            ""FieldID"":55
        },
        ""self"":{
            ""id"":""2"",
            ""name"":""Address Map""
        }
    }
}";

JToken outer = JToken.Parse(json);
JObject inner = outer["ADDRESS_MAP"].Value<JObject>();

List<string> keys = inner.Properties().Select(p => p.Name).ToList();

foreach (string k in keys)
{
    Console.WriteLine(k);
}

Output:

ADDRESS_LOCATION
LOCATION
FLOOR_NUMBER

Hope this helps you

If you are trying to generate thumbnails, you must first resize the image using imagecopyresampled();. You must resize the image so that the size of the smaller side of the image is equal to the corresponding side of the thumb.

For example, if your source image is 1280x800px and your thumb is 200x150px, you must resize your image to 240x150px and then crop it to 200x150px. This is so that the aspect ratio of the image won't change.

Here's a general formula for creating thumbnails:

$image = imagecreatefromjpeg($_GET['src']);
$filename = 'images/cropped_whatever.jpg';

$thumb_width = 200;
$thumb_height = 150;

$width = imagesx($image);
$height = imagesy($image);

$original_aspect = $width / $height;
$thumb_aspect = $thumb_width / $thumb_height;

if ( $original_aspect >= $thumb_aspect )
{
   // If image is wider than thumbnail (in aspect ratio sense)
   $new_height = $thumb_height;
   $new_width = $width / ($height / $thumb_height);
}
else
{
   // If the thumbnail is wider than the image
   $new_width = $thumb_width;
   $new_height = $height / ($width / $thumb_width);
}

$thumb = imagecreatetruecolor( $thumb_width, $thumb_height );

// Resize and crop
imagecopyresampled($thumb,
                   $image,
                   0 - ($new_width - $thumb_width) / 2, // Center the image horizontally
                   0 - ($new_height - $thumb_height) / 2, // Center the image vertically
                   0, 0,
                   $new_width, $new_height,
                   $width, $height);
imagejpeg($thumb, $filename, 80);

Haven't tested this but it should work.

EDIT

Now tested and working.

There are a couple of ways:

To delete it directly:

SomeModel.objects.filter(id=id).delete()

To delete it from an instance:

instance1 = SomeModel.objects.get(id=id)
instance1.delete()

// don't use same name

In case anyone still has to support legacy fancybox with jQuery 3.0+ here are some other changes you'll have to make:

.unbind() deprecated

Replace all instances of .unbind with .off

.removeAttribute() is not a function

Change lines 580-581 to use jQuery's .removeAttr() instead:

Old code:

580: content[0].style.removeAttribute('filter');
581: wrap[0].style.removeAttribute('filter');

New code:

580: content.removeAttr('filter');
581: wrap.removeAttr('filter');

This combined with the other patch mentioned above solved my compatibility issues.

function instantiateEmptyObject(obj: object): object {
    if (obj == null) { return {}; }

    const prototype = Object.getPrototypeOf(obj);
    if (!prototype) {
        return {};
    }

    return Object.create(prototype);
}

function quickCopy(src: object, dest: object): object {
    if (dest == null) { return dest; }

    return { ...src, ...dest };
}

quickCopy(src, instantiateEmptyObject(new Customer()));

JohannesD's answer is correct, but I feel it isn't entirely clear on an aspect of the problem.

The example he gives declares and initializes the variable i in case 1, and then tries to use it in case 2. His argument is that if the switch went straight to case 2, i would be used without being initialized, and this is why there's a compilation error. At this point, one could think that there would be no problem if variables declared in a case were never used in other cases. For example:

switch(choice) {
    case 1:
        int i = 10; // i is never used outside of this case
        printf("i = %d\n", i);
        break;
    case 2:
        int j = 20; // j is never used outside of this case
        printf("j = %d\n", j);
        break;
}

One could expect this program to compile, since both i and j are used only inside the cases that declare them. Unfortunately, in C++ it doesn't compile: as Ciro Santilli ???? ???? ??? explained, we simply can't jump to case 2:, because this would skip the declaration with initialization of i, and even though case 2 doesn't use i at all, this is still forbidden in C++.

Interestingly, with some adjustments (an #ifdef to #include the appropriate header, and a semicolon after the labels, because labels can only be followed by statements, and declarations do not count as statements in C), this program does compile as C:

// Disable warning issued by MSVC about scanf being deprecated
#ifdef _MSC_VER
#define _CRT_SECURE_NO_WARNINGS
#endif

#ifdef __cplusplus
#include <cstdio>
#else
#include <stdio.h>
#endif

int main() {

    int choice;
    printf("Please enter 1 or 2: ");
    scanf("%d", &choice);

    switch(choice) {
        case 1:
            ;
            int i = 10; // i is never used outside of this case
            printf("i = %d\n", i);
            break;
        case 2:
            ;
            int j = 20; // j is never used outside of this case
            printf("j = %d\n", j);
            break;
    }
}

Thanks to an online compiler like http://rextester.com you can quickly try to compile it either as C or C++, using MSVC, GCC or Clang. As C it always works (just remember to set STDIN!), as C++ no compiler accepts it.

The only way to get the iOS dictation is to sign up yourself through Nuance: http://dragonmobile.nuancemobiledeveloper.com/ - it's expensive, because it's the best. Presumably, Apple's contract prevents them from exposing an API.

The built in iOS accessibility features allow immobilized users to access dictation (and other keyboard buttons) through tools like VoiceOver and Assistive Touch. It may not be worth reinventing this if your users might be familiar with these tools.

In Java terms, Scala's Seq would be Java's List, and Scala's List would be Java's LinkedList.

Note that Seq is a trait, which is equivalent to Java's interface, but with the equivalent of up-and-coming defender methods. Scala's List is an abstract class that is extended by Nil and ::, which are the concrete implementations of List.

So, where Java's List is an interface, Scala's List is an implementation.

Beyond that, Scala's List is immutable, which is not the case of LinkedList. In fact, Java has no equivalent to immutable collections (the read only thing only guarantees the new object cannot be changed, but you still can change the old one, and, therefore, the "read only" one).

Scala's List is highly optimized by compiler and libraries, and it's a fundamental data type in functional programming. However, it has limitations and it's inadequate for parallel programming. These days, Vector is a better choice than List, but habit is hard to break.

Seq is a good generalization for sequences, so if you program to interfaces, you should use that. Note that there are actually three of them: collection.Seq, collection.mutable.Seq and collection.immutable.Seq, and it is the latter one that is the "default" imported into scope.

There's also GenSeq and ParSeq. The latter methods run in parallel where possible, while the former is parent to both Seq and ParSeq, being a suitable generalization for when parallelism of a code doesn't matter. They are both relatively newly introduced, so people doesn't use them much yet.

You can't call something that doesn't exist. Since you haven't created an object, the non-static method doesn't exist yet. A static method (by definition) always exists.

Even though this is pretty old, I thought I would point out a cool feature I just found for listing tags with commits:

git log --decorate=full

It will show the branches which end/start at a commit, and the tags for commits.

Just proposing a modernized version of @FelipeMiosso's answer:

According to this page, it's ∞.

You need to explicitly ask for the content type.

Add this line:

 request.ContentType = "application/json; charset=utf-8";

Because:

• Sometimes you're writing XML data, and you can't use HTML entities in a XML file.
• Because htmlentities substitutes more characters than htmlspecialchars. This is unnecessary, makes the PHP script less efficient and the resulting HTML code less readable.

htmlentities is only necessary if your pages use encodings such as ASCII or LATIN-1 instead of UTF-8 and you're handling data with an encoding different from the page's.

org.junit.Assert.assertEquals() and org.junit.Assert.assertArrayEquals() do the job.

To avoid next questions: If you want to ignore the order put all elements to set and then compare: Assert.assertEquals(new HashSet<String>(one), new HashSet<String>(two))

If however you just want to ignore duplicates but preserve the order wrap you list with LinkedHashSet.

Yet another tip. The trick Assert.assertEquals(new HashSet<String>(one), new HashSet<String>(two)) works fine until the comparison fails. In this case it shows you error message with to string representations of your sets that can be confusing because the order in set is almost not predictable (at least for complex objects). So, the trick I found is to wrap the collection with sorted set instead of HashSet. You can use TreeSet with custom comparator.

Well I had the same exact requirement, and Robot class is perfectly fine for me. It works on windows 7 and XP (tried java 6 & 7).

public static void click(int x, int y) throws AWTException{
    Robot bot = new Robot();
    bot.mouseMove(x, y);    
    bot.mousePress(InputEvent.BUTTON1_DOWN_MASK);
    bot.mouseRelease(InputEvent.BUTTON1_DOWN_MASK);
}

May be you could share the name of the program that is rejecting your click?

This should do the trick:

ddply(myvec,~name,summarise,number_of_distinct_orders=length(unique(order_no)))

This requires package plyr.

Personally, I have create a file.sh (right 755) in the root directory, file who do this job, on order of the crontab.

Crontab code:

10 2 * * * root /root/backupautomatique.sh

File.sh code:

rm -f /home/mordb-148-251-89-66.sql.gz #(To erase the old one)

mysqldump mor | gzip > /home/mordb-148-251-89-66.sql.gz (what you have done)

scp -P2222 /home/mordb-148-251-89-66.sql.gz root@otherip:/home/mordbexternes/mordb-148-251-89-66.sql.gz

(to send a copy somewhere else if the sending server crashes, because too old, like me ;-))

Your method needs to return a ActionResult type:

public ActionResult Index()
{
    //All we want to do is redirect to the class selection page
    return RedirectToAction("SelectClasses", "Registration");
}

Try:

name = "^aH^ai"
name = name:gsub("%^a", "")

If your dates column does not contain time information, you could get away with:

WHERE dates BETWEEN '20121211' and '20121213'

However, given your dates column is actually datetime, you want this

WHERE dates >= '20121211'
  AND dates < '20121214'  -- i.e. 00:00 of the next day

Another option for SQL Server 2008 onwards that retains SARGability (ability to use index for good performance) is:

WHERE CAST(dates as date) BETWEEN '20121211' and '20121213'

Note: always use ISO-8601 format YYYYMMDD with SQL Server for unambiguous date literals.

There is an error on $.map() invocation, try this:

    function getData(data) {
        this.productID = data.product_id;
        this.productData = data.product_data;
        this.imageID = data.product_data.image_id;
        this.text = data.product_data.text;
        this.link = data.product_data.link;
        this.imageUrl = data.product_data.image_url;
    }

    $.getJSON("json.json?sdfsdfg").done(function (data) {

        var allPosts = $.map(data,function (item) {

            for (var i = 0; i < item.length; i++) {
                new getData(item[i]);
            };

        });

    }); 

The error in your code was that you made return in your AJAX call, so it executed only one time.

What may be happening is that your console is closing before you get a chance to see the output. I would add Console.ReadLine(); after your Console.WriteLine("Hello World"); so your code would look something like this:

static void Main(string[] args)
    {
        Console.WriteLine("Hello World");
        Console.ReadLine();

    }

This way, the console will display "Hello World" and a blinking cursor underneath. The Console.ReadLine(); is the key here, the program waits for the users input before closing the console window.

If you develop in Visual Studio 2013 and 2015 versions, you can use their GPU Usage tool:

• GPU Usage Tool in Visual Studio (video) https://www.youtube.com/watch?v=Gjc5bPXGkTE
• GPU Usage Visual Studio 2015 https://msdn.microsoft.com/en-us/library/mt126195.aspx
• GPU Usage tool in Visual Studio 2013 Update 4 CTP1 (blog) http://blogs.msdn.com/b/vcblog/archive/2014/09/05/gpu-usage-tool-in-visual-studio-2013-update-4-ctp1.aspx
• GPU Usage for DirectX in Visual Studio (blog) http://blogs.msdn.com/b/ianhu/archive/2014/12/16/gpu-usage-for-directx-in-visual-studio.aspx

Screenshot from MSDN:

Moreover, it seems you can diagnose any application with it, not only Visual Studio Projects:

In addition to Visual Studio projects you can also collect GPU usage data on any loose .exe applications that you have sitting around. Just open the executable as a solution in Visual Studio and then start up a diagnostics session and you can target it with GPU usage. This way if you are using some type of engine or alternative development environment you can still collect data on it as long as you end up with an executable.

You can use the parse method from the URL module in the request callback.

var http = require('http');
var url = require('url');

// Configure our HTTP server to respond with Hello World to all requests.
var server = http.createServer(function (request, response) {
  var queryData = url.parse(request.url, true).query;
  response.writeHead(200, {"Content-Type": "text/plain"});

  if (queryData.name) {
    // user told us their name in the GET request, ex: http://host:8000/?name=Tom
    response.end('Hello ' + queryData.name + '\n');

  } else {
    response.end("Hello World\n");
  }
});

// Listen on port 8000, IP defaults to 127.0.0.1
server.listen(8000);

I suggest you read the HTTP module documentation to get an idea of what you get in the createServer callback. You should also take a look at sites like http://howtonode.org/ and checkout the Express framework to get started with Node faster.

Using NewRequest just to create an URL is an overkill. Use the net/url package:

package main

import (
    "fmt"
    "net/url"
)

func main() {
    base, err := url.Parse("http://www.example.com")
    if err != nil {
        return
    }

    // Path params
    base.Path += "this will get automatically encoded"

    // Query params
    params := url.Values{}
    params.Add("q", "this will get encoded as well")
    base.RawQuery = params.Encode() 

    fmt.Printf("Encoded URL is %q\n", base.String())
}

Playground: https://play.golang.org/p/YCTvdluws-r

The rule is as following :

A B 

B as a descendant of A

A > B 

B as a child of A

So

div.dropdown *

and not

div.dropdown > *

You'll want to tackle this a few ways:

1. Look for the favicon.ico at the root of the domain

   www.domain.com/favicon.ico

2. Look for a <link> tag with the rel="shortcut icon" attribute

   <link rel="shortcut icon" href="/favicon.ico" />

3. Look for a <link> tag with the rel="icon" attribute

   <link rel="icon" href="/favicon.png" />

The latter two will usually yield a higher quality image.

Just to cover all of the bases, there are device specific icon files that might yield higher quality images since these devices usually have larger icons on the device than a browser would need:

<link rel="apple-touch-icon" href="images/touch.png" />

<link rel="apple-touch-icon-precomposed" href="images/touch.png" />

And to download the icon without caring what the icon is you can use a utility like http://www.google.com/s2/favicons which will do all of the heavy lifting:

var client = new System.Net.WebClient();

client.DownloadFile(
    @"http://www.google.com/s2/favicons?domain=stackoverflow.com",
    "stackoverflow.com.ico");

Just set the TextBox.PasswordChar property to '*'.

You can easily do that by using lazy loading in react. For that you have to use lazy and suspense from react like that.

import React, { lazy, Suspense } from 'react';

const loadable = (importFunc, { fallback = null } = { fallback: null }) => {
  const LazyComponent = lazy(importFunc);

  return props => (
    <Suspense fallback={fallback}>
      <LazyComponent {...props} />
    </Suspense>
  );
};

export default loadable;

After that export your components like this.

export const TeacherTable = loadable(() =>
  import ('./MainTables/TeacherTable'), {
    fallback: <Loading />,
  });

And then in your routes file use it like this.

 <Route exact path="/app/view/teachers" component={TeacherTable} />

Thats it now you are good to go everytime your DOM is rendering your Loading compnent will be displayed as we have specified in the fallback property above. Just make sure that you do any ajax request only in componentDidMount()

Try passing width=200 as additional paramater when creating the Label.

This should work in creating label with specified width.

If you want to change it later, you can use:

label.config(width=200)

As you want to change the size of font itself you can try:

label.config(font=("Courier", 44))

You can use plain javascript, this will call your_func once, after 5 seconds:

setTimeout(function() { your_func(); }, 5000);

If your function has no parameters and no explicit receiver you can call directly setTimeout(func, 5000)

There is also a plugin I've used once. It has oneTime and everyTime methods.

• jQuery timers plugin

For me how it worked is, I have two executable versions of python so on pip install it was installing in one version but my executable path version is different so it failed, then I changed the path in sys's environment variable and installed in the executable version of python and it was able to identify the package from site-packages

If you are using toolbar from AppCompat (android.support.v7.widget.Toolbar, >= revision 24, June 2016), the padding between the icon and the title can be changed with the following value :

  app:contentInsetStartWithNavigation="0dp"

To improve my answer, you can use it on your toolbar directly inside your activity or you can create a new layout file for your toolbar. In this case, you just have to import your toolbar's @id using the include property on each needed views.

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:elevation="4dp"
    app:contentInsetLeft="0dp"
    app:contentInsetStart="0dp"
    app:contentInsetStartWithNavigation="0dp">
</android.support.v7.widget.Toolbar>

You can then import your layout on your activity.xml

<include
        layout="@layout/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

Because I know it's possible in while conditions, but I'm not sure if I'm doing it wrong for the if-statement or if it's just not possible.

HINT: what type while and if condition should be ??

If it can be done with while, it can be done with if statement as weel, as both of them expect a boolean condition.

First type

 i

to enter the commit message then press ESC then type

 :wq

to save the commit message and to quit. Or type

 :q!

to quit without saving the message.

Others have commented on the (incorrect) use of 2/11 to specify the desired interval.

I personally however prefer writing things like that using ANSI interval literals which makes reading the query much easier:

sysdate - interval '2' hour

It also has the advantage of being portable, many DBMS support this. Plus I don't have to fire up a calculator to find out how many hours the expression means - I'm pretty bad with mental arithmetics ;)

Your class shoud look something like this:

class Something {     int[] array; //global array, replace type of course     void function1() {        array = new int[10]; //let say you declare it here that will be 10 integers in size     }     void function2() {        array[0] = 12; //assing value at index 0 to 12.     } } 

That way you array will be accessible in both functions. However, you must be careful with global stuff, as you can quickly overwrite something.

This is so simple to do on a PC: Windows OS: Send the os a command to change the text: import os

os.system('color a') #green text
print 'I like green' 
raw_input('do you?')

You didn't bind all your bindings here

$sql = "SELECT SQL_CALC_FOUND_ROWS *, UNIX_TIMESTAMP(publicationDate) AS publicationDate     FROM comments WHERE articleid = :art 
ORDER BY " . mysqli_escape_string($order) . " LIMIT :numRows";

$st = $conn->prepare( $sql );
$st->bindValue( ":art", $art, PDO::PARAM_INT );

You've declared a binding called :numRows but you never actually bind anything to it.

UPDATE 2019: I keep getting upvotes on this and that reminded me of another suggestion

Double quotes are string interpolation in PHP, so if you're going to use variables in a double quotes string, it's pointless to use the concat operator. On the flip side, single quotes are not string interpolation, so if you've only got like one variable at the end of a string it can make sense, or just use it for the whole string.

In fact, there's a micro op available here since the interpreter doesn't care about parsing the string for variables. The boost is nearly unnoticable and totally ignorable on a small scale. However, in a very large application, especially good old legacy monoliths, there can be a noticeable performance increase if strings are used like this. (and IMO, it's easier to read anyway)

os.path.getsize(path)

Return the size, in bytes, of path. Raise os.error if the file does not exist or is inaccessible.

on unix vim --version tells you the various locations of the vim config files :

   system vimrc file: "$VIM/vimrc"
     user vimrc file: "$HOME/.vimrc"
 2nd user vimrc file: "~/.vim/vimrc"
      user exrc file: "$HOME/.exrc"
       defaults file: "$VIMRUNTIME/defaults.vim"
  fall-back for $VIM: "/usr/share/vim"

The answer, given by Alexandru is working quite nice. As he said, it is important that this "accessor"-view is added as the last element. Here is some code which did the trick for me:

        ...

        ...

            </LinearLayout>

        </LinearLayout>

    </FrameLayout>

</LinearLayout>

<!-- place a FrameLayout (match_parent) as the last child -->
<FrameLayout
    android:id="@+id/icon_frame_container"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
</FrameLayout>

</TabHost>

in Java:

final MaterialDialog materialDialog = (MaterialDialog) dialogInterface;

FrameLayout frameLayout = (FrameLayout) materialDialog
        .findViewById(R.id.icon_frame_container);

frameLayout.setOnTouchListener(
        new OnSwipeTouchListener(ShowCardActivity.this) {

So, there is no way to 100% be sure they are selecting the same file unless you store each file and compare them programmatically.

The way you interact with files (what JS does when the user 'uploads' a file) is HTML5 File API and JS FileReader.

https://www.html5rocks.com/en/tutorials/file/dndfiles/

https://scotch.io/tutorials/use-the-html5-file-api-to-work-with-files-locally-in-the-browser

These tutorials show you how to capture and read the metadata (stored as js object) when a file is uploaded.

Create a function that fires 'onChange' that will read->store->compare metadata of the current file against the previous files. Then you can trigger your event when the desired file is selected.

This is what a constant expression in Java looks like:

package com.mycompany.mypackage;

public class MyLinks {
  // constant expression
  public static final String GUESTBOOK_URL = "/guestbook";
}

You can use it with annotations as following:

import com.mycompany.mypackage.MyLinks;

@WebServlet(urlPatterns = {MyLinks.GUESTBOOK_URL})
public class GuestbookServlet extends HttpServlet {
  // ...
}

This actually does make a (potentially) huge difference to the optimizer in the compiler. Compilers have actually had this feature for years via the empty throw() statement after a function definition, as well as propriety extensions. I can assure you that modern compilers do take advantage of this knowledge to generate better code.

Almost every optimization in the compiler uses something called a "flow graph" of a function to reason about what is legal. A flow graph consists of what are generally called "blocks" of the function (areas of code that have a single entrance and a single exit) and edges between the blocks to indicate where flow can jump to. Noexcept alters the flow graph.

You asked for a specific example. Consider this code:

void foo(int x) {
    try {
        bar();
        x = 5;
        // Other stuff which doesn't modify x, but might throw
    } catch(...) {
        // Don't modify x
    }

    baz(x); // Or other statement using x
}

The flow graph for this function is different if bar is labeled noexcept (there is no way for execution to jump between the end of bar and the catch statement). When labeled as noexcept, the compiler is certain the value of x is 5 during the baz function - the x=5 block is said to "dominate" the baz(x) block without the edge from bar() to the catch statement.

It can then do something called "constant propagation" to generate more efficient code. Here if baz is inlined, the statements using x might also contain constants and then what used to be a runtime evaluation can be turned into a compile-time evaluation, etc.

Anyway, the short answer: noexcept lets the compiler generate a tighter flow graph, and the flow graph is used to reason about all sorts of common compiler optimizations. To a compiler, user annotations of this nature are awesome. The compiler will try to figure this stuff out, but it usually can't (the function in question might be in another object file not visible to the compiler or transitively use some function which is not visible), or when it does, there is some trivial exception which might be thrown that you're not even aware of, so it can't implicitly label it as noexcept (allocating memory might throw bad_alloc, for example).

Do not forget that you also can pass these use variables by reference.

The use cases are when you need to change the use'd variable from inside of your callback (e.g. produce the new array of different objects from some source array of objects).

$sourcearray = [ (object) ['a' => 1], (object) ['a' => 2]];
$newarray = [];
array_walk($sourcearray, function ($item) use (&$newarray) {
    $newarray[] = (object) ['times2' => $item->a * 2];
});
var_dump($newarray);

Now $newarray will comprise (pseudocode here for brevity) [{times2:2},{times2:4}].

On the contrary, using $newarray with no & modifier would make outer $newarray variable be read-only accessible from within the closure scope. But $newarray within closure scope would be a completelly different newly created variable living only within the closure scope.

Despite both variables' names are the same these would be two different variables. The outer $newarray variable would comprise [] in this case after the code has finishes.

You can directly access BODY.values:

for (var ln = 0; ln < names.length; ln++) {
  var item1 = {
    "person": {
      "_path": "/people/"+names[ln],
    },
  };

  BODY.values.push(item1);
}

The most flexible and elegant answer for Junit 4 I found in the Mkyong blog. It has the flexibility of the try/catch using the @Rule annotation. I like this approach because you can read specific attributes of a customized exception.

package com.mkyong;

import com.mkyong.examples.CustomerService;
import com.mkyong.examples.exception.NameNotFoundException;
import org.junit.Rule;
import org.junit.Test;
import org.junit.rules.ExpectedException;

import static org.hamcrest.CoreMatchers.containsString;
import static org.hamcrest.CoreMatchers.is;
import static org.hamcrest.Matchers.hasProperty;

public class Exception3Test {

    @Rule
    public ExpectedException thrown = ExpectedException.none();

    @Test
    public void testNameNotFoundException() throws NameNotFoundException {

        //test specific type of exception
        thrown.expect(NameNotFoundException.class);

        //test message
        thrown.expectMessage(is("Name is empty!"));

        //test detail
        thrown.expect(hasProperty("errCode"));  //make sure getters n setters are defined.
        thrown.expect(hasProperty("errCode", is(666)));

        CustomerService cust = new CustomerService();
        cust.findByName("");

    }

}

To force LF line endings for all text files, you can create .gitattributes file in top-level of your repository with the following lines (change as desired):

# Ensure all C and PHP files use LF.
*.c         eol=lf
*.php       eol=lf

which ensures that all files that Git considers to be text files have normalized (LF) line endings in the repository (normally core.eol configuration controls which one do you have by default).

Based on the new attribute settings, any text files containing CRLFs should be normalized by Git. If this won't happen automatically, you can refresh a repository manually after changing line endings, so you can re-scan and commit the working directory by the following steps (given clean working directory):

$ echo "* text=auto" >> .gitattributes
$ rm .git/index     # Remove the index to force Git to
$ git reset         # re-scan the working directory
$ git status        # Show files that will be normalized
$ git add -u
$ git add .gitattributes
$ git commit -m "Introduce end-of-line normalization"

or as per GitHub docs:

git add . -u
git commit -m "Saving files before refreshing line endings"
git rm --cached -r . # Remove every file from Git's index.
git reset --hard # Rewrite the Git index to pick up all the new line endings.
git add . # Add all your changed files back, and prepare them for a commit.
git commit -m "Normalize all the line endings" # Commit the changes to your repository.

See also: @Charles Bailey post.

In addition, if you would like to exclude any files to not being treated as a text, unset their text attribute, e.g.

manual.pdf      -text

Or mark it explicitly as binary:

# Denote all files that are truly binary and should not be modified.
*.png binary
*.jpg binary

To see some more advanced git normalization file, check .gitattributes at Drupal core:

# Drupal git normalization
# @see https://www.kernel.org/pub/software/scm/git/docs/gitattributes.html
# @see https://www.drupal.org/node/1542048

# Normally these settings would be done with macro attributes for improved
# readability and easier maintenance. However macros can only be defined at the
# repository root directory. Drupal avoids making any assumptions about where it
# is installed.

# Define text file attributes.
# - Treat them as text.
# - Ensure no CRLF line-endings, neither on checkout nor on checkin.
# - Detect whitespace errors.
#   - Exposed by default in `git diff --color` on the CLI.
#   - Validate with `git diff --check`.
#   - Deny applying with `git apply --whitespace=error-all`.
#   - Fix automatically with `git apply --whitespace=fix`.

Here's a bash script to check the maximum limit of a remote server (uses curl and perl).

You just need some kind of an url that can be extended with 'x' and always return 200 (or adapt it to your needs). At some point it will break and the script will display the max length.

Here's the code:

url='http://someurl/someendpoint?var1=blah&token='
ok=0
times=1

while :; do
    length=$((times+${#url}))
    echo trying with $length
    token=$(perl -le 'print "x"x'$times)
    result=$(curl -sLw '%{http_code}' -o /dev/null "${url}${token}")

    if [[ $result == 200 ]]; then
        if [[ $ok == $times ]]; then
            echo "max length is $length"
            break
        fi
        ok=$times
        times=$((times+1024))
    else
        times=$(((times+ok)/2))
    fi
done

For people wondering, this also works for button click. For example:

private void btn_Click(object sender, EventArgs e)
        {
            MessageBox.Show("Test")
        }

private void txb_KeyPress(object sender, KeyPressEventArgs e)
        {
            if (e.KeyChar == (char)13)
            {
                btn_Click(sender, e);
            }

When pressing Enter in the textfield(txb) in this case it will click the button which will active the MessageBox.

Coarse-grained granularity does not always mean bigger components, if you go by literally meaning of the word coarse, it means harsh, or not appropriate. e.g. In software projects management, if you breakdown a small system into few components, which are equal in size, but varies in complexities and features, this could lead to a coarse-grained granularity. In reverse, for a fine-grained breakdown, you would divide the components based on their cohesiveness of the functionalities each component is providing.

Ken's answer is basically right but I'd like to chime in on the "why would you want to use one over the other?" part of your question.

Basics

The base interface you choose for your repository has two main purposes. First, you allow the Spring Data repository infrastructure to find your interface and trigger the proxy creation so that you inject instances of the interface into clients. The second purpose is to pull in as much functionality as needed into the interface without having to declare extra methods.

The common interfaces

The Spring Data core library ships with two base interfaces that expose a dedicated set of functionalities:

• CrudRepository - CRUD methods
• PagingAndSortingRepository - methods for pagination and sorting (extends CrudRepository)

Store-specific interfaces

The individual store modules (e.g. for JPA or MongoDB) expose store-specific extensions of these base interfaces to allow access to store-specific functionality like flushing or dedicated batching that take some store specifics into account. An example for this is deleteInBatch(…) of JpaRepository which is different from delete(…) as it uses a query to delete the given entities which is more performant but comes with the side effect of not triggering the JPA-defined cascades (as the spec defines it).

We generally recommend not to use these base interfaces as they expose the underlying persistence technology to the clients and thus tighten the coupling between them and the repository. Plus, you get a bit away from the original definition of a repository which is basically "a collection of entities". So if you can, stay with PagingAndSortingRepository.

Custom repository base interfaces

The downside of directly depending on one of the provided base interfaces is two-fold. Both of them might be considered as theoretical but I think they're important to be aware of:

1. Depending on a Spring Data repository interface couples your repository interface to the library. I don't think this is a particular issue as you'll probably use abstractions like Page or Pageable in your code anyway. Spring Data is not any different from any other general purpose library like commons-lang or Guava. As long as it provides reasonable benefit, it's just fine.
2. By extending e.g. CrudRepository, you expose a complete set of persistence method at once. This is probably fine in most circumstances as well but you might run into situations where you'd like to gain more fine-grained control over the methods expose, e.g. to create a ReadOnlyRepository that doesn't include the save(…) and delete(…) methods of CrudRepository.

The solution to both of these downsides is to craft your own base repository interface or even a set of them. In a lot of applications I have seen something like this:

interface ApplicationRepository<T> extends PagingAndSortingRepository<T, Long> { }

interface ReadOnlyRepository<T> extends Repository<T, Long> {

  // Al finder methods go here
}

The first repository interface is some general purpose base interface that actually only fixes point 1 but also ties the ID type to be Long for consistency. The second interface usually has all the find…(…) methods copied from CrudRepository and PagingAndSortingRepository but does not expose the manipulating ones. Read more on that approach in the reference documentation.

Summary - tl;dr

The repository abstraction allows you to pick the base repository totally driven by you architectural and functional needs. Use the ones provided out of the box if they suit, craft your own repository base interfaces if necessary. Stay away from the store specific repository interfaces unless unavoidable.

I think it would be smart to only show the hand/pointer cursor when JavaScript is available. So people will not have the feeling they can click on something that is not clickable.

To achieve that you could use the JavaScript libary jQuery to add the CSS to the element like so

$("li").css({"cursor":"pointer"});

Or chain it directly to the click handler.

Or when modernizer in combination with <html class="no-js"> is used, the CSS would look like this:

.js li { cursor: pointer; }

I came to this question via Google, searching for a way to convert an already loaded image to grayscale.

Here is a way to do it with SciPy:

import scipy.misc
import scipy.ndimage

# Load an example image
# Use scipy.ndimage.imread(file_name, mode='L') if you have your own
img = scipy.misc.face()

# Convert the image
R = img[:, :, 0]
G = img[:, :, 1]
B = img[:, :, 2]
img_gray = R * 299. / 1000 + G * 587. / 1000 + B * 114. / 1000

# Show the image
scipy.misc.imshow(img_gray)

As of MySQL 8.0.18 This works fine for me

This function will inject css whenever you call the function appendStyle like this:
appendStyle('css you want to inject')

This works by injecting a style node into the head of the document. This is a similar technique to what is commonly used to lazy-load JavaScript. It works consistently in most modern browsers.

appendStyle = function (content) {_x000D_
  style = document.createElement('STYLE');_x000D_
  style.type = 'text/css';_x000D_
  style.appendChild(document.createTextNode(content));_x000D_
  document.head.appendChild(style);_x000D_
}

<!DOCTYPE html>_x000D_
<html lang="en">_x000D_
_x000D_

You can also lazy-load external CSS files by using the following snippet:

  link.rel = 'stylesheet';_x000D_
  link.href = content;_x000D_

The below program will be compatible with Java 9+ version only...

To get the CurrentProcess information,

public class CurrentProcess {
    public static void main(String[] args) {
        ProcessHandle handle = ProcessHandle.current();
        System.out.println("Current Running Process Id: "+handle.pid());
        ProcessHandle.Info info = handle.info();
        System.out.println("ProcessHandle.Info : "+info);
    }
}

For all running processes,

import java.util.List;
import java.util.stream.Collectors;

public class AllProcesses {
    public static void main(String[] args) {
        ProcessHandle.allProcesses().forEach(processHandle -> {
            System.out.println(processHandle.pid()+" "+processHandle.info());
        });
    }
}

Go to terminal type:

alias python=python3.x

This will setup default python as python3.x

Here is my demo of modal window that auto-resize to its content and starts scrolling when it does not fit the window.

Modal window demo (see comments in the HTML source code)

All done only with HTML and CSS - no JS required to display and resize the modal window (but you still need it to display the window of course - in new version you don't need JS at all).

Update (more demos):

• Modal window aligned to top

• Centered Modal window

• Old demo that use Javascript

The point is to have outer and inner DIVs where the outer one defines the fixed position and the inner creates the scrolling. (In the demo there are actually more DIVs to make them look like an actual modal window.)

        #modal {
            position: fixed;
            transform: translate(0,0);
            width: auto; left: 0; right: 0;
            height: auto; top: 0; bottom: 0;
            z-index: 990; /* display above everything else */
            padding: 20px; /* create padding for inner window - page under modal window will be still visible */
        }

        #modal .outer {
            box-sizing: border-box; -moz-box-sizing: border-box; -webkit-box-sizing: border-box; -o-box-sizing: border-box;
            width: 100%;
            height: 100%;
            position: relative;
            z-index: 999;
        }

        #modal .inner {
            box-sizing: border-box; -moz-box-sizing: border-box; -webkit-box-sizing: border-box; -o-box-sizing: border-box;
            width: 100%;
            height: auto;       /* allow to fit content (if smaller)... */
            max-height: 100%;   /* ... but make sure it does not overflow browser window */

            /* allow vertical scrolling if required */
            overflow-x: hidden;
            overflow-y: auto;

            /* definition of modal window layout */
            background: #ffffff;
            border: 2px solid #222222;
            border-radius: 16px; /* some nice (modern) round corners */
            padding: 16px;       /* make sure inner elements does not overflow round corners */
        }

Zip your file (.zip) and IE will give the user the option to open or download the file.

I have used in this way. Its Working fine!

$rules = [

            'password' => [

                    'required',

                    'string',

                    'min:6',

                'max:12',             // must be at least 8 characters in length

                ],

            'confirm_password' => 'required|same:password|min:6'

        ];

This worked for me:

echo(header('content-type: text/xml'));

I observed that when I removed SessionMode from the ServiceContract attribute, the issue went away.

Example:

[ServiceContract(SessionMode=SessionMode.Required, CallbackContract=typeof(ICallbacks))]
 public interface IStringReverser
 {
   [OperationContract]
   string ReverseString(string value);
 }

to...

[ServiceContract()]
 public interface IStringReverser
 {
   [OperationContract]
   string ReverseString(string value);
 }

Optimum buffer size is related to a number of things: file system block size, CPU cache size and cache latency.

Most file systems are configured to use block sizes of 4096 or 8192. In theory, if you configure your buffer size so you are reading a few bytes more than the disk block, the operations with the file system can be extremely inefficient (i.e. if you configured your buffer to read 4100 bytes at a time, each read would require 2 block reads by the file system). If the blocks are already in cache, then you wind up paying the price of RAM -> L3/L2 cache latency. If you are unlucky and the blocks are not in cache yet, the you pay the price of the disk->RAM latency as well.

This is why you see most buffers sized as a power of 2, and generally larger than (or equal to) the disk block size. This means that one of your stream reads could result in multiple disk block reads - but those reads will always use a full block - no wasted reads.

Now, this is offset quite a bit in a typical streaming scenario because the block that is read from disk is going to still be in memory when you hit the next read (we are doing sequential reads here, after all) - so you wind up paying the RAM -> L3/L2 cache latency price on the next read, but not the disk->RAM latency. In terms of order of magnitude, disk->RAM latency is so slow that it pretty much swamps any other latency you might be dealing with.

So, I suspect that if you ran a test with different cache sizes (haven't done this myself), you will probably find a big impact of cache size up to the size of the file system block. Above that, I suspect that things would level out pretty quickly.

There are a ton of conditions and exceptions here - the complexities of the system are actually quite staggering (just getting a handle on L3 -> L2 cache transfers is mind bogglingly complex, and it changes with every CPU type).

This leads to the 'real world' answer: If your app is like 99% out there, set the cache size to 8192 and move on (even better, choose encapsulation over performance and use BufferedInputStream to hide the details). If you are in the 1% of apps that are highly dependent on disk throughput, craft your implementation so you can swap out different disk interaction strategies, and provide the knobs and dials to allow your users to test and optimize (or come up with some self optimizing system).

My .zip file was formatted correctly (I think) but it wasn't working. Even unchecking "Group items by category" didn't work

To install it I did so:

• unzip the .zip archive
• Help -> Install New Software...
• Add... -> Archive...
• I selected the "content.jar" file

At this point Eclipse read the plugin correctly, I went ahead, accepted the conditions and then asked me to restart the IDE.

I found the best answer for my purposes was to use:

.topics tr { 
    overflow: hidden;
    height: 14px;
    white-space: nowrap;
}

The white-space: nowrap is important as it prevents your row's cells from breaking across multiple lines.

I personally like to add text-overflow: ellipsis to my th and td elements to make the overflowing text look nicer by adding the trailing fullstops, for example Too long gets dots...

>>> import urlparse
>>> url = 'http://stackoverflow.com/questions/1234567/blah-blah-blah-blah'
>>> urlparse.urljoin(url, '/')
'http://stackoverflow.com/'

Try this

#/bin/bash

read -p "Enter a word: " word
echo "You entered $word"

This will grab records with strings (in the fieldName column) that are 10 characters long:

 select * from table where length(fieldName)=10

If you are just looking to get a single value from the XML you may want to use Java's XPath library. For an example see my answer to a previous question:

• How to use XPath on xml docs having default namespace

It would look something like:

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.xpath.XPath;
import javax.xml.xpath.XPathConstants;
import javax.xml.xpath.XPathFactory;

import org.w3c.dom.Document;
import org.w3c.dom.NodeList;

public class Demo {

    public static void main(String[] args) {
        DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
        try {
            DocumentBuilder builder = domFactory.newDocumentBuilder();
            Document dDoc = builder.parse("E:/test.xml");

            XPath xPath = XPathFactory.newInstance().newXPath();
            Node node = (Node) xPath.evaluate("/Request/@name", dDoc, XPathConstants.NODE);
            System.out.println(node.getNodeValue());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

}

You won't be able to restore from 2012 to 2008. You will be able to use a tool like red-gate SQL compare to copy the schema etc (provided nothing 2012 specific is used). If you have data to copy across too, you can use their Data Compare tool, and I think you get a 14 day free trial.

You can send mail from localhost with sendmail package , sendmail package is inbuild in XAMPP. So if you are using XAMPP then you can easily send mail from localhost.

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

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

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

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

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

[sendmail]

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

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

PS: don't forgot to replace my-gmail-id and my-gmail-password in above code. Also, don't forget to remove duplicate keys if you copied settings from above. For example comment following line if there is another sendmail_path : sendmail_path="C:\xampp\mailtodisk\mailtodisk.exe" in the php.ini file

Also remember to restart the server using the XAMMP control panel so the changes take effect.

For gmail please check https://support.google.com/accounts/answer/6010255 to allow access from less secure apps.

To send email on Linux (with sendmail package) through Gmail from localhost please check PHP+Ubuntu Send email using gmail form localhost.

In your case, if you want to Foo.talk():

function Foo() {};
// But use Foo.talk would be inefficient
Foo.talk = function () {
    alert('hello~\n');
};

Foo.talk(); // 'hello~\n'

But it's an inefficient way to implement, using prototype is better.

Another way, My way is defined as static class:

var Foo = new function() {
  this.talk = function () {
    alert('hello~\n');
    };
};

Foo.talk(); // 'hello~\n'

Above static class doesn't need to use prototype because it will be only constructed once as static usage.

Note that starting Python 3.8, the standard library provides the math.comb function to compute the binomial coefficient:

math.comb(n, k)

which is the number of ways to choose k items from n items without repetition
n! / (k! (n - k)!):

import math
math.comb(10, 5)  # 252
math.comb(10, 10) # 1

Wireshark + OSX + iOS:

Great overview so far, but if you want specifics for Wireshark + OSX + iOS:

• install Wireshark on your computer
• connect iOS device to computer via USB cable
• connect iOS device and computer to the same WiFi network
• run this command in a OSX terminal window: rvictl -s x where x is the UDID of your iOS device. You can find the UDID of your iOS device via iTunes (make sure you are using the UDID and not the serial number).
• goto Wireshark Capture->Options, a dialog box appears, click on the line rvi0 then press the Start button.

Now you will see all network traffic on the iOS device. It can be pretty overwhelming. A couple of pointers:

• don't use iOS with a VPN, you don't be able to make sense of the encrypted traffic
• use simple filters to focus on interesting traffic
• ip.addr==204.144.14.134 views traffic with a source or destination address of 204.144.14.134
• http views only http traffic

Here's a sample window depicting TCP traffic for for pdf download from 204.144.14.134:

I too got the same error, when I did this behind a proxy. But after I exported the following from a terminal and re-tried the same command, the problem got resolved:

export http_proxy="http://username:password@proxy_ip_addr:port/"
export https_proxy="https://username:password@proxy_ip_addr:port/"

Based on my highly scientific and accurate experiment, it tops out on my machine well before 1,000,000,000 characters. (I'm still running the code below to get a better pinpoint).

This fixed my issue AFTER ensuring my ports were all uniquely sorted out.

Use:

ToolTip tip = new ToolTip();
private void richTextBox1_MouseMove(object sender, MouseEventArgs e)
{
    Cursor a = System.Windows.Forms.Cursor.Current;
    if (a == Cursors.Hand)
    {
        Point p = richTextBox1.Location;
        tip.Show(
            GetWord(richTextBox1.Text,
                richTextBox1.GetCharIndexFromPosition(e.Location)),
            this,
            p.X + e.X,
            p.Y + e.Y + 32,
            1000);
    }
}

Use the GetWord function from my other answer to get the hovered word. Use timer logic to disable reshow the tooltip as in prev. example.

In this example right above, the tool tip shows the hovered word by checking the mouse pointer.

If this answer is still not what you are looking fo, please specify the condition that characterizes the word you want to use tooltip on. If you want it for bolded word, please tell me.

http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1230935955 states:

By default, the Arduino IDE and libraries does not use the operator new and operator delete. It does support malloc() and free(). So the solution is to implement new and delete operators for yourself, to use these functions.

Code:

#include <stdlib.h> // for malloc and free
void* operator new(size_t size) { return malloc(size); } 
void operator delete(void* ptr) { free(ptr); }

This let's you create objects, e.g.

C* c; // declare variable
c = new C(); // create instance of class C
c->M(); // call method M
delete(c); // free memory

I haven't used Angular, but reading the link above, it seems that you're trying to code for something that you don't need to handle. You make changes to state in your React component hierarchy (via this.setState()) and React will cause your component to be re-rendered (effectively 'listening' for changes). If you want to 'listen' from another component in your hierarchy then you have two options:

1. Pass handlers down (via props) from a common parent and have them update the parent's state, causing the hierarchy below the parent to be re-rendered.
2. Alternatively, to avoid an explosion of handlers cascading down the hierarchy, you should look at the flux pattern, which moves your state into data stores and allows components to watch them for changes. The Fluxxor plugin is very useful for managing this.

If none of the solutions above worked, try this 10-second fix.

Navigate to the startup project in solution explorer. Right click, properties > Application > Target framework. Change the target framework to anything else. Press Yes for the confirmation dialog. Give the changes a few seconds to take effect, then switch the framework back to what it was before.

The error will hopefully go away for you like it did for me!

For a quick fix to your problem, change your ; to a comma , and eliminate the spaces between email addresses

You need this:

$('.container').each(function(){  
     var $columns = $('.column',this);
     var maxHeight = Math.max.apply(Math, $columns.map(function(){
         return $(this).height();
     }).get());
     $columns.height(maxHeight);
});

Explanation

• The following snippet constructs an array of the heights:

  $columns.map(function(){
      return $(this).height();
  }).get()
  

• Math.max.apply( Math, array ) finds the maximum of array items

• $columns.height(maxHeight); sets all columns' height to maximum height.

The bias helps to get a better equation

Imagine the input and output like a function y = ax + b and you need to put the right line between the input(x) and output(y) to minimise the global error between each point and the line , if you keep the equation like this y = ax , you will have one parameter for adaptation only , even if you find the best a minimising the global error it will be kind of far from the wanted value

You can say the bias makes the equation more flexible to adapt to the best values

For multiple plots in a single pdf file you can use PdfPages

In the plotGraph function you should return the figure and than call savefig of the figure object.

------ plotting module ------

def plotGraph(X,Y):
      fig = plt.figure()
      ### Plotting arrangements ###
      return fig

------ plotting module ------

----- mainModule ----

from matplotlib.backends.backend_pdf import PdfPages

plot1 = plotGraph(tempDLstats, tempDLlabels)
plot2 = plotGraph(tempDLstats_1, tempDLlabels_1)
plot3 = plotGraph(tempDLstats_2, tempDLlabels_2)

pp = PdfPages('foo.pdf')
pp.savefig(plot1)
pp.savefig(plot2)
pp.savefig(plot3)
pp.close()

Just a shot in the dark(since you did not share the compiler initialization code with us): the way you retrieve the compiler causes the issue. Point your JRE to be inside the JDK as unlike jdk, jre does not provide any tools hence, results in NPE.

I'm a new user for Spring. I found a different solution for this. Using reflection and making public necessary fields and assign mock objects.

This is my auth controller and it has some Autowired private properties.

@RestController
public class AuthController {

    @Autowired
    private UsersDAOInterface usersDao;

    @Autowired
    private TokensDAOInterface tokensDao;

    @RequestMapping(path = "/auth/getToken", method = RequestMethod.POST)
    public @ResponseBody Object getToken(@RequestParam String username,
            @RequestParam String password) {
        User user = usersDao.getLoginUser(username, password);

        if (user == null)
            return new ErrorResult("Kullaniciadi veya sifre hatali");

        Token token = new Token();
        token.setTokenId("aergaerg");
        token.setUserId(1);
        token.setInsertDatetime(new Date());
        return token;
    }
}

And this is my Junit test for AuthController. I'm making public needed private properties and assign mock objects to them and rock :)

public class AuthControllerTest {

    @Test
    public void getToken() {
        try {
            UsersDAO mockUsersDao = mock(UsersDAO.class);
            TokensDAO mockTokensDao = mock(TokensDAO.class);

            User dummyUser = new User();
            dummyUser.setId(10);
            dummyUser.setUsername("nixarsoft");
            dummyUser.setTopId(0);

            when(mockUsersDao.getLoginUser(Matchers.anyString(), Matchers.anyString())) //
                    .thenReturn(dummyUser);

            AuthController ctrl = new AuthController();

            Field usersDaoField = ctrl.getClass().getDeclaredField("usersDao");
            usersDaoField.setAccessible(true);
            usersDaoField.set(ctrl, mockUsersDao);

            Field tokensDaoField = ctrl.getClass().getDeclaredField("tokensDao");
            tokensDaoField.setAccessible(true);
            tokensDaoField.set(ctrl, mockTokensDao);

            Token t = (Token) ctrl.getToken("test", "aergaeg");

            Assert.assertNotNull(t);

        } catch (Exception ex) {
            System.out.println(ex);
        }
    }

}

I don't know advantages and disadvantages for this way but this is working. This technic has a little bit more code but these codes can be seperated by different methods etc. There are more good answers for this question but I want to point to different solution. Sorry for my bad english. Have a good java to everybody :)

It would seem that any of the answers which implement an ORDER BY clause in the solution is missing the point, or does not actually understand what TOP returns to you.

TOP returns an unordered query result set which limits the record set to the first N records returned. (From an Oracle perspective, it is akin to adding a where ROWNUM < (N+1).

Any solution which uses an order, may return rows which also are returned by the TOP clause (since that data set was unordered in the first place), depending on what criteria was used in the order by

The usefulness of TOP is that once the dataset reaches a certain size N, it stops fetching rows. You can get a feel for what the data looks like without having to fetch all of it.

To implement BOTTOM accurately, it would need to fetch the entire dataset unordered and then restrict the dataset to the final N records. That will not be particularly effective if you are dealing with huge tables. Nor will it necessarily give you what you think you are asking for. The end of the data set may not necessarily be "the last rows inserted" (and probably won't be for most DML intensive applications).

Similarly, the solutions which implement an ORDER BY are, unfortunately, potentially disastrous when dealing with large data sets. If I have, say, 10 Billion records and want the last 10, it is quite foolish to order 10 Billion records and select the last 10.

The problem here, is that BOTTOM does not have the meaning that we think of when comparing it to TOP.

When records are inserted, deleted, inserted, deleted over and over and over again, some gaps will appear in the storage and later, rows will be slotted in, if possible. But what we often see, when we select TOP, appears to be sorted data, because it may have been inserted early on in the table's existence. If the table does not experience many deletions, it may appear to be ordered. (e.g. creation dates may be as far back in time as the table creation itself). But the reality is, if this is a delete-heavy table, the TOP N rows may not look like that at all.

So -- the bottom line here(pun intended) is that someone who is asking for the BOTTOM N records doesn't actually know what they're asking for. Or, at least, what they're asking for and what BOTTOM actually means are not the same thing.

So -- the solution may meet the actual business need of the requestor...but does not meet the criteria for being the BOTTOM.

if you give a 2D array to the plot function of matplotlib it will assume the columns to be lines:

If x and/or y is 2-dimensional, then the corresponding columns will be plotted.

In your case your shape is not accepted (100, 1, 1, 8000). As so you can using numpy squeeze to solve the problem quickly:

np.squeez doc: Remove single-dimensional entries from the shape of an array.

import numpy as np
import matplotlib.pyplot as plt

data = np.random.randint(3, 7, (10, 1, 1, 80))
newdata = np.squeeze(data) # Shape is now: (10, 80)
plt.plot(newdata) # plotting by columns
plt.show()

But notice that 100 sets of 80 000 points is a lot of data for matplotlib. I would recommend that you look for an alternative. The result of the code example (run in Jupyter) is:

When adding datepicker at runtime generated input textboxes you have to check if it already contains datepicker then first remove class hasDatepicker then apply datePicker to it.

function convertTxtToDate() {
        $('.dateTxt').each(function () {
            if ($(this).hasClass('hasDatepicker')) {
                $(this).removeClass('hasDatepicker');
            } 
             $(this).datepicker();
        });
    } 

Try Html.EditorFor helper method instead of Html.TextBoxFor.

In ruby:

str = "a"
100_000_000.times {puts str.next!}

It is quite fast, but it is going to take some time =). Of course, you can start at "aaaaaaaa" if the short strings aren't interesting to you.

I might have misinterpreted the actual question though - in one of the posts it sounded as if you just needed a bruteforce library of strings, but in the main question it sounds like you need to permutate a particular string.

Your problem is somewhat similar to this one: http://beust.com/weblog/archives/000491.html (list all integers in which none of the digits repeat themselves, which resulted in a whole lot of languages solving it, with the ocaml guy using permutations, and some java guy using yet another solution).

Rookie, if you want to write a file to server by socket, how about using fileoutputstream instead of dataoutputstream? dataoutputstream is more fit for protocol-level read-write. it is not very reasonable for your code in bytes reading and writing. loop to read and write is necessary in java io. and also, you use a buffer way. flush is necessary. here is a code sample: http://www.rgagnon.com/javadetails/java-0542.html

This is known as a line magic in iPython. They are unique in that their arguments only extend to the end of the current line, and magics themselves are really structured for command line development. timeit is used to time the execution of code.

If you wanted to see all of the magics you can use, you could simply type:

%lsmagic

to get a list of both line magics and cell magics.

Some further magic information from documentation here:

IPython has a system of commands we call magics that provide effectively a mini command language that is orthogonal to the syntax of Python and is extensible by the user with new commands. Magics are meant to be typed interactively, so they use command-line conventions, such as using whitespace for separating arguments, dashes for options and other conventions typical of a command-line environment.

Depending on whether you are in line or cell mode, there are two different ways to use %timeit. Your question illustrates the first way:

In [1]: %timeit range(100)

vs.

In [1]: %%timeit 
      : x = range(100)
      :

HTML: Use names as

<input name="levels[level][]">
<input name="levels[build_time][]">

PHP:

$array = filter_input_array(INPUT_POST);
$newArray = array();
foreach (array_keys($array) as $fieldKey) {
    foreach ($array[$fieldKey] as $key=>$value) {
        $newArray[$key][$fieldKey] = $value;
    }
}  

$newArray will hold data as you want

Array ( 
  [0] => Array ( [level] => 1 [build_time] => 123 ) 
  [1] => Array ( [level] => 2 [build_time] => 456 )

                        .icon(BitmapDescriptorFactory.fromResource(R.drawable.markerb)));

                String TotalDistance = gd.getTotalDistanceText(doc);
                String TotalDuration = gd.getTotalDurationText(doc);
            }
        });

        gd.request(start, end, GoogleDirection.MODE_DRIVING);
    }
}

You can use the spread operator to re-assign props with a standard functional component. The thing I like about this approach is that you can mix required props with optional ones that have a default value.

interface MyProps {
   text: string;
   optionalText?: string;
}

const defaultProps = {
   optionalText = "foo";
}

const MyComponent = (props: MyProps) => {
   props = { ...defaultProps, ...props }
}

This works just fine, but instead of

name = input('Enter name of text file: ')+'.txt' 

you should use

name = raw_input('Enter name of text file: ')+'.txt'

along with

open(name,'a') or open(name,'w')

in Javascript already exists constants. You define a constant like this:

const name1 = value;

This cannot change through reassignment.

You can accomplish this using the function FILL to create filled polygons under the sections of your plots. You will want to plot the lines and polygons in the order you want them to be stacked on the screen, starting with the bottom-most one. Here's an example with some sample data:

x = 1:100;             %# X range
y1 = rand(1,100)+1.5;  %# One set of data ranging from 1.5 to 2.5
y2 = rand(1,100)+0.5;  %# Another set of data ranging from 0.5 to 1.5
baseLine = 0.2;        %# Baseline value for filling under the curves
index = 30:70;         %# Indices of points to fill under

plot(x,y1,'b');                              %# Plot the first line
hold on;                                     %# Add to the plot
h1 = fill(x(index([1 1:end end])),...        %# Plot the first filled polygon
          [baseLine y1(index) baseLine],...
          'b','EdgeColor','none');
plot(x,y2,'g');                              %# Plot the second line
h2 = fill(x(index([1 1:end end])),...        %# Plot the second filled polygon
          [baseLine y2(index) baseLine],...
          'g','EdgeColor','none');
plot(x(index),baseLine.*ones(size(index)),'r');  %# Plot the red line

And here's the resulting figure:

You can also change the stacking order of the objects in the figure after you've plotted them by modifying the order of handles in the 'Children' property of the axes object. For example, this code reverses the stacking order, hiding the green polygon behind the blue polygon:

kids = get(gca,'Children');        %# Get the child object handles
set(gca,'Children',flipud(kids));  %# Set them to the reverse order

Finally, if you don't know exactly what order you want to stack your polygons ahead of time (i.e. either one could be the smaller polygon, which you probably want on top), then you could adjust the 'FaceAlpha' property so that one or both polygons will appear partially transparent and show the other beneath it. For example, the following will make the green polygon partially transparent:

set(h2,'FaceAlpha',0.5);

All these answers are partially wrong.

Microsoft has clarified that Community is for ANY USE as long as your revenue is under $1 Million US dollars. That is literally the only difference between Pro and Community. Corporate or free or not, irrelevant.

Even the lack of TFS support is not true. I can verify it is present and works perfectly.

EDIT: Here is an MSDN post regarding the $1M limit: MSDN (hint: it's in the VS 2017 license)

EDIT: Even over the revenue limit, open source is still free.

This is an alternative:

- name: Install this only for local dev machine
  pip: name=pyramid
  delegate_to: localhost

simply "CUT" project folder and move it out of workspace directory and do the following

file=>import=>(select new directory)=> mark (copy to my workspace) checkbox 

and you done !

this is for classes

$('.nameofdiv').val('we are developers');

for ids

$('#nameofdiv').val('we are developers');

now if u have an iput in a form u can use

$("#form li.name input.name_val").val('we are awsome developers');

You can use .indexOf():

if(str.indexOf(substr) > -1) {

}

As of Ansible 2.0 there seems to be an option called strategy on a playbook. When setting the strategy to free, the playbook plays tasks on each host without waiting to the others. See http://docs.ansible.com/ansible/playbooks_strategies.html.

It looks something like this (taken from the above link):

- hosts: all
  strategy: free
  tasks:
  ...

Please note that I didn't check this and I'm very new to Ansible. I was just curious about doing what you described and happened to come acroess this strategy thing.

EDIT:

It seems like this is not exactly what you're trying to do. Maybe "async tasks" is more appropriate as described here: http://docs.ansible.com/ansible/playbooks_async.html.

This includes specifying async and poll on a task. The following is taken from the 2nd link I mentioned:

- name: simulate long running op, allow to run for 45 sec, fire and forget
  command: /bin/sleep 15
  async: 45
  poll: 0

I guess you can specify longer async times if your task is lengthy. You can probably define your three concurrent task this way.

I actually had the same problem with a completely new repository. I had even tried creating one with git checkout -b master, but it would not create the branch. I then realized if I made some changes and committed them, git created my master branch.

The Watcher method fires on every character input. So, I built this code based on onFocusChange method:

public static boolean comS(String s1,String s2){
    if (s1.length()==s2.length()){
        int l=s1.length();
        for (int i=0;i<l;i++){
            if (s1.charAt(i)!=s2.charAt(i))return false;
        }
        return true;
    }
    return false;
}

public void onChange(final EditText EdTe, final Runnable FRun){
    class finalS{String s="";}
    final finalS dat=new finalS();  
    EdTe.setOnFocusChangeListener(new OnFocusChangeListener() {          
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if (hasFocus) {dat.s=""+EdTe.getText();}
            else if (!comS(dat.s,""+EdTe.getText())){(new Handler()).post(FRun);}       
        }
    });
}

To using it, just call like this:

onChange(YourEditText, new Runnable(){public void run(){
    // V  V    YOUR WORK HERE

    }}
);

You can ignore the comS function by replace the !comS(dat.s,""+EdTe.getText()) with !equal function. However the equal function itself some time work not correctly in run time.

The onChange listener will remember old data of EditText when user focus typing, and then compare the new data when user lose focus or jump to other input. If comparing old String not same new String, it fires the work.

If you only have 1 EditText, then u will need to make a ClearFocus function by making an Ultimate Secret Transparent Micro EditText outside the windows and request focus to it, then hide the keyboard via Import Method Manager.

I know this is an old thread, but thought I may add on a little extra. In my case I was wanting to pass on the text, val and some other data attr. In this case its better to store the whole option as a prev value rather than just the val.

Example code below:

var $sel = $('your select');
$sel.data("prevSel", $sel.clone());
$sel.on('change', function () {
    //grab previous select
    var prevSel = $(this).data("prevSel");

    //do what you want with the previous select
    var prevVal = prevSel.val();
    var prevText = prevSel.text();
    alert("option value - " + prevVal + " option text - " + prevText)

    //reset prev val        
    $(this).data("prevSel", $(this).clone());
});

EDIT:

I forgot to add .clone() onto the element. in not doing so when you try to pull back the values you end up pulling in the new copy of the select rather than the previous. Using the clone() method stores a copy of the select instead of an instance of it.

Besides the "accented letters are sorted differently than unaccented ones" in some Western European languages, you must take into account the groups of letters, which sometimes are sorted differently, also.

Traditionally, in Spanish, "ch" was considered a letter in its own right, same with "ll" (both of which represent a single phoneme), so a list would get sorted like this:

• caballo
• cinco
• coche
• charco
• chocolate
• chueco
• dado
• (...)
• lámpara
• luego
• llanta
• lluvia
• madera

Notice all the words starting with single c go together, except words starting with ch which go after them, same with ll-starting words which go after all the words starting with a single l. This is the ordering you'll see in old dictionaries and encyclopedias, sometimes even today by very conservative organizations.

The Royal Academy of the Language changed this to make it easier for Spanish to be accomodated in the computing world. Nevertheless, ñ is still considered a different letter than n and goes after it, and before o. So this is a correctly ordered list:

• Namibia
• número
• ñandú
• ñú
• obra
• ojo

By selecting the correct collation, you get all this done for you, automatically :-)

• In my particular case, the problem looks like a bug in Visual Studio - because the error didn't make any sense! This is what worked for me: perhaps it may work for you as well?

Solution: Try Re-building the solution

• Short cut to re-build: CTRL + SHIFT + B

You can simply add DISTINCT in front.

SELECT GROUP_CONCAT(DISTINCT categories SEPARATOR ' ')

if you want to sort,

SELECT GROUP_CONCAT(DISTINCT categories ORDER BY categories ASC SEPARATOR ' ')

I change the input type on my checkbox, so on my OnCheckedChangeListener i do:

passwordEdit.setInputType(InputType.TYPE_CLASS_TEXT| (isChecked? InputType.TYPE_TEXT_VARIATION_PASSWORD|~InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD : InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD));

And it finally worked.

Seems like a boolean problem with TYPE_TEXT_VARIATION_VISIBLE_PASSWORD. Invert the flag and it should fix the problem.

In your case:

password.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD|~InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD);

A little simpler than Lars' answer:

something_needs_directory_xxx : xxx/..

and generic rule:

%/.. : ;@mkdir -p $(@D)

No touch-files to clean up or make .PRECIOUS :-)

I was using AngularJS and AngularStrap 2.3.7 and trying to catch the 'change' event by listening to a <form> element (not the input itself) and none of the answers here worked for me. I tried to do:

$(form).on('change change.dp dp.change changeDate' function () {...})

And nothing would fire. I ended up listening to the focus and blur events and setting a custom property before/after on the element itself:

// special hack to make bs-datepickers fire change events
// use timeout to make sure they all exist first
$timeout(function () {  
    $('input[bs-datepicker]').on('focus', function (e){
        e.currentTarget.focusValue = e.currentTarget.value;
    });        
    $('input[bs-datepicker]').on('blur', function (e){
        if (e.currentTarget.focusValue !== e.currentTarget.value) {
            var event = new Event('change', { bubbles: true });
            e.currentTarget.dispatchEvent(event);
        }
    });
})

This basically manually checks the value before and after the focus and blur and dispatches a new 'change' event. The { bubbles: true } bit is what got the form to detect the change. If you have any datepicker elements inside of an ng-if you'll need to wrap the listeners in a $timeout to make sure the digest happens first so all of your datepicker elements exist.

Hope this helps someone!

You can get the id of the last transaction by running lastInsertId() method on the connection object($conn).

Like this $lid = $conn->lastInsertId();

Using ASCII(RIGHT(ProductAlternateKey, 1)) you can see that the right most character in row 2 is a Line Feed or Ascii Character 10.

This can not be removed using the standard LTrim RTrim functions.

You could however use (REPLACE(ProductAlternateKey, CHAR(10), '')

You may also want to account for carriage returns and tabs. These three (Line feeds, carriage returns and tabs) are the usual culprits and can be removed with the following :

LTRIM(RTRIM(REPLACE(REPLACE(REPLACE(ProductAlternateKey, CHAR(10), ''), CHAR(13), ''), CHAR(9), '')))

If you encounter any more "white space" characters that can't be removed with the above then try one or all of the below:

--NULL
Replace([YourString],CHAR(0),'');
--Horizontal Tab
Replace([YourString],CHAR(9),'');
--Line Feed
Replace([YourString],CHAR(10),'');
--Vertical Tab
Replace([YourString],CHAR(11),'');
--Form Feed
Replace([YourString],CHAR(12),'');
--Carriage Return
Replace([YourString],CHAR(13),'');
--Column Break
Replace([YourString],CHAR(14),'');
--Non-breaking space
Replace([YourString],CHAR(160),'');

This list of potential white space characters could be used to create a function such as :

Create Function [dbo].[CleanAndTrimString] 
(@MyString as varchar(Max))
Returns varchar(Max)
As
Begin
    --NULL
    Set @MyString = Replace(@MyString,CHAR(0),'');
    --Horizontal Tab
    Set @MyString = Replace(@MyString,CHAR(9),'');
    --Line Feed
    Set @MyString = Replace(@MyString,CHAR(10),'');
    --Vertical Tab
    Set @MyString = Replace(@MyString,CHAR(11),'');
    --Form Feed
    Set @MyString = Replace(@MyString,CHAR(12),'');
    --Carriage Return
    Set @MyString = Replace(@MyString,CHAR(13),'');
    --Column Break
    Set @MyString = Replace(@MyString,CHAR(14),'');
    --Non-breaking space
    Set @MyString = Replace(@MyString,CHAR(160),'');

    Set @MyString = LTRIM(RTRIM(@MyString));
    Return @MyString
End
Go

Which you could then use as follows:

Select 
    dbo.CleanAndTrimString(ProductAlternateKey) As ProductAlternateKey
from DimProducts
