moveToTop is the proper way.

z-Index is not correct. It works initially, but multiple dialogs will continue to float underneath the one you altered with z-index. No good.

Just in case anybody is trying to find if an indexPath is among the selected ones (like in a UICollectionView or UITableView cellForItemAtIndexPath functions):

    var isSelectedItem = false
    if let selectedIndexPaths = collectionView.indexPathsForSelectedItems() as? [NSIndexPath]{
        if contains(selectedIndexPaths, indexPath) {
            isSelectedItem = true
        }
    }

@marioosh added some extra information regarding cipher suite encryption .

A cipher suite is a collection of symmetric and asymmetric encryption algorithms used by hosts to establish a secure communication in Transport Layer Security (TLS) / Secure Sockets Layer (SSL) network protocol.
Ciphers are algorithms, more specifically they’re a set of steps for both performing encryption as well as the corresponding decryption.

A cipher suite specifies one algorithm for each of the following tasks:

• Key exchange
• Bulk encryption
• Message authentication

SocketFactory « Default handshaking protocols « To avoid SSLException use https.protocols system property.
This contains a comma-separated list of protocol suite names specifying which protocol suites to enable on this HttpsURLConnection. See the SSLSocket.setEnabledProtocols(String[]) method.

System.setProperty("https.protocols", "SSLv3");
// (OR)
System.setProperty("https.protocols", "TLSv1");

JAVA8 « TLS 1.1 and TLS 1.2 Enabled by Default: The SunJSSE provider enables the protocols TLS 1.1 and TLS 1.2 on the client by default.

System.setProperty("https.protocols", "TLSv1,TLSv1.1,TLSv1.2");

Example for Java8 Network File:

public class SecureSocket {
    static {
        // System.setProperty("javax.net.debug", "all");
        System.setProperty("https.protocols", "TLSv1,TLSv1.1,TLSv1.2");
    }
    public static void main(String[] args) {
        String GhitHubSSLFile = "https://raw.githubusercontent.com/Yash-777/SeleniumWebDrivers/master/pom.xml";
        try {
            String str = readCloudFileAsString(GhitHubSSLFile);
                    // new String(Files.readAllBytes(Paths.get( "D:/Sample.file" )));

            System.out.println("Cloud File Data : "+ str);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    public static String readCloudFileAsString( String urlStr ) throws java.io.IOException {
        if( urlStr != null && urlStr != "" ) {
            java.io.InputStream s = null;
            String content = null;
            try {
                URL url = new URL( urlStr );
                s = (java.io.InputStream) url.getContent();
                content = IOUtils.toString(s, "UTF-8");
            } finally {
                if (s != null) s.close(); 
            }
            return content.toString();
        }
        return null;
    }
}

System.setProperty("javax.net.debug", "all");

Exception

javax.net.ssl.SSLException: Received fatal alert: protocol_version

If handshaking fails for any reason, the SSLSocket is closed, and no further communications can be done.

The 2nd call to Enable-Migrations is failing because the Configuration.cs file already exists. If you rename that class and file, you should be able to run that 2nd Enable-Migrations, which will create another Configuration.cs.

You will then need to specify which configuration you want to use when updating the databases.

For me the issue got resolved by doing the following:

Navigated to Tool --> Options --> Project and Solutions --> Web Projects

I could find the first check box "Use the 64 bit version of IIS Express of web sites and projects" was unchecked.

Selecting this check box helped me in launching the WCF Client.

A sorting algorithm is said to be stable if two objects with equal keys appear in the same order in sorted output as they appear in the input array to be sorted. Some sorting algorithms are stable by nature like Insertion sort, Merge Sort, Bubble Sort, etc. And some sorting algorithms are not, like Heap Sort, Quick Sort, etc.

Background: a "stable" sorting algorithm keeps the items with the same sorting key in order. Suppose we have a list of 5-letter words:

peach
straw
apple
spork

If we sort the list by just the first letter of each word then a stable-sort would produce:

apple
peach
straw
spork

In an unstable sort algorithm, straw or spork may be interchanged, but in a stable one, they stay in the same relative positions (that is, since straw appears before spork in the input, it also appears before spork in the output).

We could sort the list of words using this algorithm: stable sorting by column 5, then 4, then 3, then 2, then 1. In the end, it will be correctly sorted. Convince yourself of that. (by the way, that algorithm is called radix sort)

Now to answer your question, suppose we have a list of first and last names. We are asked to sort "by last name, then by first". We could first sort (stable or unstable) by the first name, then stable sort by the last name. After these sorts, the list is primarily sorted by the last name. However, where last names are the same, the first names are sorted.

You can't stack unstable sorts in the same fashion.

Complementing the above answers and also "Parroting" from the Windows Dev Center documentation,

The Winsock2.h header file internally includes core elements from the Windows.h header file, so there is not usually an #include line for the Windows.h header file in Winsock applications. If an #include line is needed for the Windows.h header file, this should be preceded with the #define WIN32_LEAN_AND_MEAN macro. For historical reasons, the Windows.h header defaults to including the Winsock.h header file for Windows Sockets 1.1. The declarations in the Winsock.h header file will conflict with the declarations in the Winsock2.h header file required by Windows Sockets 2.0. The WIN32_LEAN_AND_MEAN macro prevents the Winsock.h from being included by the Windows.h header ..

Check these out:

• http://commons.apache.org/cli/
• http://www.martiansoftware.com/jsap/
• http://picocli.info/

Or roll your own:

• http://docs.oracle.com/javase/7/docs/api/java/util/Scanner.html

For instance, this is how you use commons-cli to parse 2 string arguments:

import org.apache.commons.cli.*;

public class Main {


    public static void main(String[] args) throws Exception {

        Options options = new Options();

        Option input = new Option("i", "input", true, "input file path");
        input.setRequired(true);
        options.addOption(input);

        Option output = new Option("o", "output", true, "output file");
        output.setRequired(true);
        options.addOption(output);

        CommandLineParser parser = new DefaultParser();
        HelpFormatter formatter = new HelpFormatter();
        CommandLine cmd;

        try {
            cmd = parser.parse(options, args);
        } catch (ParseException e) {
            System.out.println(e.getMessage());
            formatter.printHelp("utility-name", options);

            System.exit(1);
        }

        String inputFilePath = cmd.getOptionValue("input");
        String outputFilePath = cmd.getOptionValue("output");

        System.out.println(inputFilePath);
        System.out.println(outputFilePath);

    }

}

usage from command line:

$> java -jar target/my-utility.jar -i asd

If the variable ax.xaxis._autolabelpos = True, matplotlib sets the label position in function _update_label_position in axis.py according to (some excerpts):

    bboxes, bboxes2 = self._get_tick_bboxes(ticks_to_draw, renderer)
    bbox = mtransforms.Bbox.union(bboxes)
    bottom = bbox.y0
    x, y = self.label.get_position()
    self.label.set_position((x, bottom - self.labelpad * self.figure.dpi / 72.0))

You can set the label position independently of the ticks by using:

    ax.xaxis.set_label_coords(x0, y0)

that sets _autolabelpos to False or as mentioned above by changing the labelpad parameter.

change Date to Object which is between parenthesis

I am use to read full data:

// inputStream is one instance InputStream
byte[] data = new byte[inputStream.available()];
inputStream.read(data);
String dataString = new String(data);

I was facing the same problem. It works for me. Please check this.

json_encode($array,JSON_UNESCAPED_UNICODE);

You can also use:

your_dataframe.insert(loc=0, value=np.nan, column="")

where loc is your empty row index.

Try the following:

$('select').change(function(){
  alert($(this).children('option:selected').data('id'));
});

Your change subscriber subscribes to the change event of the select, so the this parameter is the select element. You need to find the selected child to get the data-id from.

Inconsolata (http://www.levien.com/type/myfonts/inconsolata.html) is a great monospaced font for programming. Earlier versions tend to act weird on OS X, but the newer versions work out very well.

}

id and class are two Global / Standard HTML attribute (The global attributes below can be used on any HTML element.)

class Specifies one or more classnames for an element (refers to a class in a style sheet)

id Specifies a unique id for an element

The id attributes gives an element document-wide unique identifier where the class attribute provides a way of classifying similar elements.

The id attribute value must be unique across the HTML page where class attribute can be reused where ever you want to apply the same properties

For Spring Boot - React js apps I added @CrssOrigin annotation on the controller and it works:

@CrossOrigin(origins = {"http://localhost:3000"})
@RestController
@RequestMapping("/api")

But take care to add localhost correct => 'http://localhost:3000', not with '/' at the end => 'http://localhost:3000/', this was my problem.

With the expression API, which based on the comments is what this question is asking for, you can use the in_ method of the relevant column.

To query

SELECT id, name FROM user WHERE id in (123,456)

use

myList = [123, 456]
select = sqlalchemy.sql.select([user_table.c.id, user_table.c.name], user_table.c.id.in_(myList))
result = conn.execute(select)
for row in result:
    process(row)

This assumes that user_table and conn have been defined appropriately.

you use that code

ImageView[] ivCard = new ImageView[1];

@override    
protected void onCreate(Bundle savedInstanceState)  

ivCard[0]=(ImageView)findViewById(R.id.imageView1);

First, you should define "doesn't work".
Second, I assume that your table field 'content' is varchar/text, so you need to enclose it in quotes. content = '{$content}'
And last but not least: use echo mysql_error() directly after a query to debug.

grid.Columns[0].HeaderText

or

grid.Columns["columnname"].HeaderText

You can simply do something like...

...
<head>
...
<script>
  window.fbAsyncInit = function() {
    FB.init({
      appId            : 'your-app-id', // you need to create an facebook app
      autoLogAppEvents : true,
      xfbml            : true,
      version          : 'v3.3'
    });
  };
</script>
<script async defer src="https://connect.facebook.net/en_US/sdk.js"></script>
</head>
<body>
...
<button id="share-btn"></button>
<!-- load jquery -->
<script>
    $('#share-btn').on('click', function () {
        FB.ui({
            method: 'share',
            href: location.href, // Current url
        }, function (response) { });
    });
</script>
</body>

Have you set the KeyStore and/or TrustStore System properties?

java -Djavax.net.ssl.keyStore=pathToKeystore -Djavax.net.ssl.keyStorePassword=123456

or from with the code

System.setProperty("javax.net.ssl.keyStore", pathToKeyStore);

Same with javax.net.ssl.trustStore

You can use below link: New line in javascript

  var i;

   var s;
   for(s=0; s<i; s = s+1){

ALT+SHIFT+G will create the auto generated comments for your method (place the cursor at starting position of your method).

Try below code:

$(document).ready(function(){
$('#about').css({'background-color':'black'});

This is the right answer

preg_match("/^[0-9]+$/", $yourstr);

This function return TRUE(1) if it matches or FALSE(0) if it doesn't

Quick Explanation :

'^' : means that it should begin with the following ( in our case is a range of digital numbers [0-9] ) ( to avoid cases like ("abdjdf125") )

'+' : means there should be at least one digit

'$' : means after our pattern the string should end ( to avoid cases like ("125abdjdf") )

Couldn't you just do something simple like this?

For i = LBound(Schedule, 1) To UBound(Schedule, 1)
  If (Schedule(i, 1) < ReferenceDate) Then
     PrevCouponIndex = i
  Else
     DF = Application.Run("SomeFunction"....)
     PV = PV + (DF * Coupon / CouponFrequency)
  End If
Next

With PowerShell 5.1 (PackageManagement module)

Install-Package -Name MyPackage -Source (Get-Location).Path -Destination C:\outputdirectory

Your output is correct. Denote the white characters of " Hello" and " This" at the beginning.

Another issue is with your methodology. Use the Arrays.sort() method:

String[] strings = { " Hello ", " This ", "Is ", "Sorting ", "Example" };
Arrays.sort(strings);

Output:

 Hello
 This
Example
Is
Sorting

Here the third element of the array "is" should be "Is", otherwise it will come in last after sorting. Because the sort method internally uses the ASCII value to sort elements.

I'm using NodeJS and got the same error. Like the other answers, the problem was also because JQuery needed to be loaded before Bootstrap; however, because of the NodeJS characteristics, this change had to be aplied in the pipeline.js file.

The change in pipeline.js was like this:

var jsFilesToInject = [
  // Dependencies like jQuery, or Angular are brought in here
  'js/dependencies/angular.1.3.js',
  'js/dependencies/jquery.js',
  'js/dependencies/bootstrap.js',
  'js/dependencies/**/*.js',
];

I'm also using grunt to help, and it automatically changed the order in the main html page:

<!--SCRIPTS-->
  <script src="/js/dependencies/angular.1.3.js"></script>
  <script src="/js/dependencies/jquery.js"></script>
  <script src="/js/dependencies/bootstrap.js"></script>
  <!-- other dependencies -->
<!--SCRIPTS END-->

Hope it helps! You didn't said what your environment was, so I decided to post this answer.

Read a File from resources folder using NIO, in java8

public static String read(String fileName) {

        Path path;
        StringBuilder data = new StringBuilder();
        Stream<String> lines = null;
        try {
            path = Paths.get(Thread.currentThread().getContextClassLoader().getResource(fileName).toURI());
            lines = Files.lines(path);
        } catch (URISyntaxException | IOException e) {
            logger.error("Error in reading propertied file " + e);
            throw new RuntimeException(e);
        }

        lines.forEach(line -> data.append(line));
        lines.close();
        return data.toString();
    }

Something like this would work

/^\d{2}$/

I was having this problem when running from c#, on Windows 7, the "Interactive Services Detection" service was popping up when running a hidden powershell window as the SYSTEM account.

Using the "CreateNoWindow" parameter prevented the ISD service popping up it's warning.

process.StartInfo = new ProcessStartInfo("powershell.exe",
    String.Format(@" -NoProfile -ExecutionPolicy unrestricted -encodedCommand ""{0}""",encodedCommand))
{
   WorkingDirectory = executablePath,
   UseShellExecute = false,
   CreateNoWindow = true
};

Just had this problem myself and accepted answer didn't help me but I solved it with:

Add reference > Browse > C: > Windows > assembly > GAC > Microsoft.Office.Interop.Excel > 12.0.0.0_etc > Microsoft.Office.Interop.Excel.dll

You can use the IGNORE keyword too, example:

 update IGNORE table set primary_field = 'value'...............

Like the following. It will make the user database owner.

EXEC sp_addrolemember N'db_owner', N'USerNAme'

I think <src> adds some resources to the page and <href> is just for providing a link to a resource(without adding the resource itself to the page).

I've had success with the following personally, but my function should probably be called something like 'ensure this directory exists':

def mkdirRecursive(dirpath):
    import os
    if os.path.isdir(dirpath): return

    h,t = os.path.split(dirpath) # head/tail
    if not os.path.isdir(h):
        mkdirRecursive(h)

    os.mkdir(join(h,t))
# end mkdirRecursive

This will work from anywhere, inside Form(), Form_Load(), or any event handler. I posted before, but I don't see it now?!?

public void exit(int exitCode)
{
    if (System.Windows.Forms.Application.MessageLoop)
    {
       // Use this since we are in a running Form
       System.Windows.Forms.Application.Exit();
       System.Environment.Exit(exitCode);
    }
    else
    {
       // Form ended or never .Run
       System.Environment.Exit(exitCode);
    }
} //* end exit()

On the latest support library none of the solutions discussed here are necessary anymore. You can play with your Activity's fragments as you like using the FragmentTransaction. Just make sure that your fragments can be identified either with an id or tag.

The fragments will be restored automatically as long as you don't try to recreate them on every call to onCreate(). Instead, you should check if savedInstanceState is not null and find the old references to the created fragments in this case.

Here is an example:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    if (savedInstanceState == null) {
        myFragment = MyFragment.newInstance();
        getSupportFragmentManager()
                .beginTransaction()
                .add(R.id.my_container, myFragment, MY_FRAGMENT_TAG)
                .commit();
    } else {
        myFragment = (MyFragment) getSupportFragmentManager()
                .findFragmentByTag(MY_FRAGMENT_TAG);
    }
...
}

Note however that there is currently a bug when restoring the hidden state of a fragment. If you are hiding fragments in your activity, you will need to restore this state manually in this case.

If you are working with ASP.NET 3.5 and lower, and your problem is relatively simple like mine, you can just return a null row from the SQL query.

if not exists (select RepId, startdate,enddate from RepTable where RepID= 10)
     select null RepID,null StartDate,null EndDate
else
     select RepId, startdate,enddate from RepTable where RepID= 10

This solution does not require any C# code or ASP.NET code

1. Make sure you cast the null columns into appropriate names, otherwise it will not work.
2. Else block must be included which is the same query as in if not exists (query part)
3. In my case if I am using @RepID instead of 10. Which is mapped to a DropDownList box outside gridview.

Each time I change the drop down to select a different rep, Gridview is updated. If no record is found, it shows a null row.

Forget aboves for vscode exclude search pattern, try to below pattern it is working for any folder in vscode last version!

!../../../locales/*

for example i have searched like below vscode example clude settings

files to include: *.js

files to exclude: **/node_modules,!../../../locales/,!../../../theme/,!../../admin/client/*

LinkedHashMap will return the elements in the order they were inserted into the map when you iterate over the keySet(), entrySet() or values() of the map.

Map<String, String> map = new LinkedHashMap<String, String>();

map.put("id", "1");
map.put("name", "rohan");
map.put("age", "26");

for (Map.Entry<String, String> entry : map.entrySet()) {
    System.out.println(entry.getKey() + " = " + entry.getValue());
}

This will print the elements in the order they were put into the map:

id = 1
name = rohan 
age = 26 

You can achieve this with a few simple extension methods. The following Date extension method returns just the timezone component in ISO format, then you can define another for the date/time part and combine them for a complete date-time-offset string.

Date.prototype.getISOTimezoneOffset = function () {
    const offset = this.getTimezoneOffset();
    return (offset < 0 ? "+" : "-") + Math.floor(Math.abs(offset / 60)).leftPad(2) + ":" + (Math.abs(offset % 60)).leftPad(2);
}

Date.prototype.toISOLocaleString = function () {
    return this.getFullYear() + "-" + (this.getMonth() + 1).leftPad(2) + "-" +
        this.getDate().leftPad(2) + "T" + this.getHours().leftPad(2) + ":" +
        this.getMinutes().leftPad(2) + ":" + this.getSeconds().leftPad(2) + "." +
        this.getMilliseconds().leftPad(3);
}

Number.prototype.leftPad = function (size) {
    var s = String(this);
    while (s.length < (size || 2)) {
        s = "0" + s;
    }
    return s;
}

Example usage:

var date = new Date();
console.log(date.toISOLocaleString() + date.getISOTimezoneOffset());
// Prints "2020-08-05T16:15:46.525+10:00"

I know it's 2020 and most people are probably using Moment.js by now, but a simple copy & pastable solution is still sometimes handy to have.

(The reason I split the date/time and offset methods is because I'm using an old Datejs library which already provides a flexible toString method with custom format specifiers, but just doesn't include the timezone offset. Hence, I added toISOLocaleString for anyone without said library.)

This is what I quickly wrote for myself:

public static class XmlDocumentExtensions
{
    public static void IterateThroughAllNodes(
        this XmlDocument doc, 
        Action<XmlNode> elementVisitor)
    {
        if (doc != null && elementVisitor != null)
        {
            foreach (XmlNode node in doc.ChildNodes)
            {
                doIterateNode(node, elementVisitor);
            }
        }
    }

    private static void doIterateNode(
        XmlNode node, 
        Action<XmlNode> elementVisitor)
    {
        elementVisitor(node);

        foreach (XmlNode childNode in node.ChildNodes)
        {
            doIterateNode(childNode, elementVisitor);
        }
    }
}

To use it, I've used something like:

var doc = new XmlDocument();
doc.Load(somePath);

doc.IterateThroughAllNodes(
    delegate(XmlNode node)
    {
        // ...Do something with the node...
    });

Maybe it helps someone out there.

I came here from golang, where it's common to see something like

if (err := doSomething(); err != nil) {
    return nil, err
}

In which err is scoped to that if block only. As such, here's what I'm doing in es6, which seems pretty ugly, but doesn't make my rather strict eslint rules whinge, and achieves the same.

{
  const err = doSomething()
  if (err != null) {
    return (null, err)
  }
}

The extra braces define a new, uh, "lexical scope"? Which means I can use const, and err isn't available to the outer block.

Shortest - 18 chars (not confuse += (mention by OP) with = more details here)

test.innerHTML=str

<div id="test"></div>

Update

Not knowing what you are trying to do, I'll share one more suggestion: Preallocate vectors of the type you want for each column, insert values into those vectors, and then, at the end, create your data.frame.

Continuing with Julian's f3 (a preallocated data.frame) as the fastest option so far, defined as:

# pre-allocate space
f3 <- function(n){
  df <- data.frame(x = numeric(n), y = character(n), stringsAsFactors = FALSE)
  for(i in 1:n){
    df$x[i] <- i
    df$y[i] <- toString(i)
  }
  df
}

Here's a similar approach, but one where the data.frame is created as the last step.

# Use preallocated vectors
f4 <- function(n) {
  x <- numeric(n)
  y <- character(n)
  for (i in 1:n) {
    x[i] <- i
    y[i] <- i
  }
  data.frame(x, y, stringsAsFactors=FALSE)
}

microbenchmark from the "microbenchmark" package will give us more comprehensive insight than system.time:

library(microbenchmark)
microbenchmark(f1(1000), f3(1000), f4(1000), times = 5)
# Unit: milliseconds
#      expr         min          lq      median         uq         max neval
#  f1(1000) 1024.539618 1029.693877 1045.972666 1055.25931 1112.769176     5
#  f3(1000)  149.417636  150.529011  150.827393  151.02230  160.637845     5
#  f4(1000)    7.872647    7.892395    7.901151    7.95077    8.049581     5

f1() (the approach below) is incredibly inefficient because of how often it calls data.frame and because growing objects that way is generally slow in R. f3() is much improved due to preallocation, but the data.frame structure itself might be part of the bottleneck here. f4() tries to bypass that bottleneck without compromising the approach you want to take.

Original answer

This is really not a good idea, but if you wanted to do it this way, I guess you can try:

for (i in 1:10) {
  df <- rbind(df, data.frame(x = i, y = toString(i)))
}

Note that in your code, there is one other problem:

• You should use stringsAsFactors if you want the characters to not get converted to factors. Use: df = data.frame(x = numeric(), y = character(), stringsAsFactors = FALSE)

Update

Dav Glass from Yahoo has given a talk at YuiConf2010 in November which is now available in Video from.

He shows to great extend how one can use YUI3 to render out widgets on the server side an make them work with GET requests when JS is disabled, or just make them work normally when it's active.

He also shows examples of how to use server side DOM to apply style sheets before rendering and other cool stuff.

The demos can be found on his GitHub Account.

The part that's missing IMO to make this really awesome, is some kind of underlying storage of the widget state. So that one can visit the page without JavaScript and everything works as expected, then they turn JS on and now the widget have the same state as before but work without page reloading, then throw in some saving to the server + WebSockets to sync between multiple open browser.... and the next generation of unobtrusive and gracefully degrading ARIA's is born.

Original Answer

Well go ahead and built it yourself then.

Seriously, 90% of all WebApps out there work fine with a REST approach, of course you could do magical things like superior user tracking, tracking of downloads in real time, checking which parts of videos are being watched etc.

One problem is scalability, as soon as you have more then 1 Node process, many (but not all) of the benefits of having the data stored between requests go away, so you have to make sure that clients always hit the same process. And even then, bigger things will yet again need a database layer.

Node.js isn't the solution to everything, I'm sure people will build really great stuff in the future, but that needs some time, right now many are just porting stuff over to Node to get things going.

What (IMHO) makes Node.js so great, is the fact that it streamlines the Development process, you have to write less code, it works perfectly with JSON, you loose all that context switching.

I mainly did gaming experiments so far, but I can for sure say that there will be many cool multi player (or even MMO) things in the future, that use both HTML5 and Node.js.

Node.js is still gaining traction, it's not even near to the RoR Hype some years ago (just take a look at the Node.js tag here on SO, hardly 4-5 questions a day).

Rome (or RoR) wasn't built over night, and neither will Node.js be.

Node.js has all the potential it needs, but people are still trying things out, so I'd suggest you to join them :)

printf ("Here are the first 8 chars: %.8s\n", "A string that is more than 8 chars");

%8s would specify a minimum width of 8 characters. You want to truncate at 8, so use %.8s.

If you want to always print exactly 8 characters you could use %8.8s

This is the way I solved my problem:

1. Right click the folder that has uncommitted changes on your local
2. Click Team > Advanced > Assume Unchanged
3. Pull from master.

UPDATE:

As Hugo Zuleta rightly pointed out, you should be careful while applying this. He says that it might end up saying the branch is up to date, but the changes aren't shown, resulting in desync from the branch.

It's an unsigned integer type exactly the size of a pointer. Whenever you need to do something unusual with a pointer - like for example invert all bits (don't ask why) you cast it to uintptr_t and manipulate it as a usual integer number, then cast back.

So I do in Windows 10 and Python 3.7.1 (tested):

import subprocess
Quellpfad = r"C:\Users\MeMySelfAndI\Desktop"
Quelldatei = r"\a.bat"
Quelle = Quellpfad + Quelldatei
print(Quelle)
subprocess.call(Quelle)

Without the use of any other library you can look at the BMP file format. I've implemented it in the past and it can be done without too much work.

Bitmap-File Structures

Each bitmap file contains a bitmap-file header, a bitmap-information header, a color table, and an array of bytes that defines the bitmap bits. The file has the following form:

BITMAPFILEHEADER bmfh;
BITMAPINFOHEADER bmih;
RGBQUAD aColors[];
BYTE aBitmapBits[];

... see the file format for more details

If you want to reset bootstrap page with button click using jQuery :

function resetForm(){
        var validator = $( "#form_ID" ).validate();
        validator.resetForm();
}

Using above code you also have change the field colour as red to normal.

If you want to reset only fielded value then :

$("#form_ID")[0].reset();

When having a column defined with "NOT NULL DEFAULT CURRENT_TIMESTAMP," inserted records will always get set with UTC/GMT time.

Here's what I did to avoid having to include the time in my INSERT/UPDATE statements:

--Create a table having a CURRENT_TIMESTAMP:
CREATE TABLE FOOBAR (
    RECORD_NO INTEGER NOT NULL,
    TO_STORE INTEGER,
    UPC CHAR(30),
    QTY DECIMAL(15,4),
    EID CHAR(16),
    RECORD_TIME NOT NULL DEFAULT CURRENT_TIMESTAMP)

--Create before update and after insert triggers:
CREATE TRIGGER UPDATE_FOOBAR BEFORE UPDATE ON FOOBAR
    BEGIN
       UPDATE FOOBAR SET record_time = datetime('now', 'localtime')
       WHERE rowid = new.rowid;
    END

CREATE TRIGGER INSERT_FOOBAR AFTER INSERT ON FOOBAR
    BEGIN
       UPDATE FOOBAR SET record_time = datetime('now', 'localtime')
       WHERE rowid = new.rowid;
    END

Test to see if it works...

--INSERT a couple records into the table:
INSERT INTO foobar (RECORD_NO, TO_STORE, UPC, PRICE, EID)
    VALUES (0, 1, 'xyz1', 31, '777')

INSERT INTO foobar (RECORD_NO, TO_STORE, UPC, PRICE, EID)
    VALUES (1, 1, 'xyz2', 32, '777')

--UPDATE one of the records:
UPDATE foobar SET price = 29 WHERE upc = 'xyz2'

--Check the results:
SELECT * FROM foobar

Hope that helps.

JSON parsing using NSJSONSerialization

   NSString* path  = [[NSBundle mainBundle] pathForResource:@"data" ofType:@"json"];
   
    //Here you can take JSON string from your URL ,I am using json file
    NSString* jsonString = [[NSString alloc] initWithContentsOfFile:path encoding:NSUTF8StringEncoding error:nil];
    NSData* jsonData = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
    NSError *jsonError;
    NSArray *jsonDataArray = [NSJSONSerialization JSONObjectWithData:[jsonString dataUsingEncoding:NSUTF8StringEncoding] options:kNilOptions error:&jsonError];
  
    NSLog(@"jsonDataArray: %@",jsonDataArray);

    NSDictionary *jsonObject = [NSJSONSerialization JSONObjectWithData:jsonData options:kNilOptions error:&jsonError];
if(jsonObject !=nil){
   // NSString *errorCode=[NSMutableString stringWithFormat:@"%@",[jsonObject objectForKey:@"response"]];
   
        
        if(![[jsonObject objectForKey:@"#data"] isEqual:@""]){
            
            NSMutableArray *array=[jsonObject objectForKey:@"#data"];
             // NSLog(@"array: %@",array);
            NSLog(@"array: %d",array.count);  
            
            int k = 0;
            for(int z = 0; z<array.count;z++){

An Alternative to AsyncTask is robospice. https://github.com/octo-online/robospice.

Some of the features of robospice.

1.executes asynchronously (in a background AndroidService) network requests (ex: REST requests using Spring Android).notify you app, on the UI thread, when result is ready.

2.is strongly typed ! You make your requests using POJOs and you get POJOs as request results.

3.enforce no constraints neither on POJOs used for requests nor on Activity classes you use in your projects.

4.caches results (in Json with both Jackson and Gson, or Xml, or flat text files, or binary files, even using ORM Lite).

5.notifies your activities (or any other context) of the result of the network request if and only if they are still alive

6.no memory leak at all, like Android Loaders, unlike Android AsyncTasks notifies your activities on their UI Thread.

7.uses a simple but robust exception handling model.

This is working for me in Angular 7. It is based on the --main option of the ng command. I am not sure if this option is undocumented and possibly subject to change, but it works for me. I put a line in my package.json file in scripts section. There using the --main option of with the ng test command, I specify the path to the .spec.ts file I want to execute. For example

"test 1": "ng test --main E:/WebRxAngularClient/src/app/test/shared/my-date-utils.spec.ts",

You can run the script as you run any such script. I run it in Webstorm by clicking on "test 1" in the npm section.

Declare them outside the subroutines, like this:

Public wbA as Workbook
Public wbB as Workbook
Sub MySubRoutine()
    Set wbA = Workbooks.Open("C:\file.xlsx")
    Set wbB = Workbooks.Open("C:\file2.xlsx")
    OtherSubRoutine
End Sub
Sub OtherSubRoutine()
    MsgBox wbA.Name, vbInformation
End Sub

Alternately, you can pass variables between subroutines:

Sub MySubRoutine()
Dim wbA as Workbook
Dim wbB as Workbook
    Set wbA = Workbooks.Open("C:\file.xlsx")
    Set wbB = Workbooks.Open("C:\file2.xlsx")
    OtherSubRoutine wbA, wbB
End Sub
Sub OtherSubRoutine(wb1 as Workbook, wb2 as Workbook)
    MsgBox wb1.Name, vbInformation
    MsgBox wb2.Name, vbInformation
End Sub

Or use Functions to return values:

Sub MySubroutine()
    Dim i as Long
    i = MyFunction()
    MsgBox i
End Sub
Function MyFunction()
    'Lots of code that does something
    Dim x As Integer, y as Double
    For x = 1 to 1000
        'Lots of code that does something
    Next
    MyFunction = y
End Function

In the second method, within the scope of OtherSubRoutine you refer to them by their parameter names wb1 and wb2. Passed variables do not need to use the same names, just the same variable types. This allows you some freedom, for example you have a loop over several workbooks, and you can send each workbook to a subroutine to perform some action on that Workbook, without making all (or any) of the variables public in scope.

A Note About User Forms

Personally I would recommend keeping Option Explicit in all of your modules and forms (this prevents you from instantiating variables with typos in their names, like lCoutn when you meant lCount etc., among other reasons).

If you're using Option Explicit (which you should), then you should qualify module-scoped variables for style and to avoid ambiguity, and you must qualify user-form Public scoped variables, as these are not "public" in the same sense. For instance, i is undefined, though it's Public in the scope of UserForm1:

You can refer to it as UserForm1.i to avoid the compile error, or since forms are New-able, you can create a variable object to contain reference to your form, and refer to it that way:

NB: In the above screenshots x is declared Public x as Long in another standard code module, and will not raise the compilation error. It may be preferable to refer to this as Module2.x to avoid ambiguity and possible shadowing in case you re-use variable names...

It depends on the Test Construct around the operator. Your options are double parentheses, double brackets, single brackets, or test.

If you use ((…)), you are testing arithmetic equality with == as in C:

$ (( 1==1 )); echo $?
0
$ (( 1==2 )); echo $?
1

(Note: 0 means true in the Unix sense and a failed test results in a non-zero number.)

Using -eq inside of double parentheses is a syntax error.

If you are using […] (or single brackets) or [[…]] (or double brackets), or test you can use one of -eq, -ne, -lt, -le, -gt, or -ge as an arithmetic comparison.

$ [ 1 -eq 1 ]; echo $?
0
$ [ 1 -eq 2 ]; echo $?
1
$ test 1 -eq 1; echo $?
0

The == inside of single or double brackets (or the test command) is one of the string comparison operators:

$ [[ "abc" == "abc" ]]; echo $?
0
$ [[ "abc" == "ABC" ]]; echo $?
1

As a string operator, = is equivalent to ==. Also, note the whitespace around = or ==: it’s required.

While you can do [[ 1 == 1 ]] or [[ $(( 1+1 )) == 2 ]] it is testing the string equality — not the arithmetic equality.

So -eq produces the result probably expected that the integer value of 1+1 is equal to 2 even though the right-hand side is a string and has a trailing space:

$ [[ $(( 1+1 )) -eq  "2 " ]]; echo $?
0

While a string comparison of the same picks up the trailing space and therefore the string comparison fails:

$ [[ $(( 1+1 )) == "2 " ]]; echo $?
1

And a mistaken string comparison can produce a completely wrong answer. 10 is lexicographically less than 2, so a string comparison returns true or 0. So many are bitten by this bug:

$ [[ 10 < 2 ]]; echo $?
0

The correct test for 10 being arithmetically less than 2 is this:

$ [[ 10 -lt 2 ]]; echo $?
1

In comments, there is a question about the technical reason why using the integer -eq on strings returns true for strings that are not the same:

$ [[ "yes" -eq "no" ]]; echo $?
0

The reason is that Bash is untyped. The -eq causes the strings to be interpreted as integers if possible including base conversion:

$ [[ "0x10" -eq 16 ]]; echo $?
0
$ [[ "010" -eq 8 ]]; echo $?
0
$ [[ "100" -eq 100 ]]; echo $?
0

And 0 if Bash thinks it is just a string:

$ [[ "yes" -eq 0 ]]; echo $?
0
$ [[ "yes" -eq 1 ]]; echo $?
1

So [[ "yes" -eq "no" ]] is equivalent to [[ 0 -eq 0 ]]

Last note: Many of the Bash specific extensions to the Test Constructs are not POSIX and therefore may fail in other shells. Other shells generally do not support [[...]] and ((...)) or ==.

I used couple of hours trying to figure how to remove background from launched modal, so far tried

.modal-backdrop {    background: none; }

Didn't work even I have tried to work with javascript like

 <script type="text/javascript">   
 $('#modal-id').on('shown.bs.modal',  function () {
       $(".modal-backdrop.in").hide();     })
</script>

Also didn't work either. I just added

data-backdrop="false"

to

<div class="modal fade" id="myModal" data-backdrop="false">......</div>

And Applying css CLASS

.modal {     background-color: transparent !important;  }

Now its working like a charm This worked with Bootstrap 3

I've found this to work:

var element1 = document.createElement("input");
element1.type = "hidden";
element1.value = "10";
element1.name = "a";
document.getElementById("chells").appendChild(element1);

It's probably not anywhere approaching a best practice, but I usually call a SIZE on the collection to load the children in the same transaction, like you have suggested. It's clean, immune to any changes in the structure of the child elements, and yields SQL with low overhead.

The Makefile builds the hello executable if any one of main.cpp, hello.cpp, factorial.cpp changed. The smallest possible Makefile to achieve that specification could have been:

hello: main.cpp hello.cpp factorial.cpp
    g++ -o hello main.cpp hello.cpp factorial.cpp

• pro: very easy to read
• con: maintenance nightmare, duplication of the C++ dependencies
• con: efficiency problem, we recompile all C++ even if only one was changed

To improve on the above, we only compile those C++ files that were edited. Then, we just link the resultant object files together.

OBJECTS=main.o hello.o factorial.o

hello: $(OBJECTS)
    g++ -o hello $(OBJECTS)

main.o: main.cpp
    g++ -c main.cpp

hello.o: hello.cpp
    g++ -c hello.cpp

factorial.o: factorial.cpp
    g++ -c factorial.cpp

• pro: fixes efficiency issue
• con: new maintenance nightmare, potential typo on object files rules

To improve on this, we can replace all object file rules with a single .cpp.o rule:

OBJECTS=main.o hello.o factorial.o

hello: $(OBJECTS)
    g++ -o hello $(OBJECTS)

.cpp.o:
    g++ -c $< -o $@

• pro: back to having a short makefile, somewhat easy to read

Here the .cpp.o rule defines how to build anyfile.o from anyfile.cpp.

• $< matches to first dependency, in this case, anyfile.cpp
• $@ matches the target, in this case, anyfile.o.

The other changes present in the Makefile are:

• Making it easier to changes compilers from g++ to any C++ compiler.
• Making it easier to change the compiler options.
• Making it easier to change the linker options.
• Making it easier to change the C++ source files and output.
• Added a default rule 'all' which acts as a quick check to ensure all your source files are present before an attempt to build your application is made.

The solution is

typeid(T).name()

which returns std::type_info.

First, edit NetworkManager.conf file:

vim /etc/NetworkManager/NetworkManager.conf

Comment this line:

#dns=dnsmasq

Finally

sudo service network-manager restart
sudo service docker restart

Since the column may be null in the database, the rs.getString() will throw a NullPointerException()

No.

rs.getString will not throw NullPointer if the column is present in the selected result set (SELECT query columns) For a particular record if value for the 'comumn is null in db, you must do something like this -

String myValue = rs.getString("myColumn");
if (rs.wasNull()) {
    myValue = ""; // set it to empty string as you desire.
}

You may want to refer to wasNull() documentation -

From java.sql.ResultSet
boolean wasNull() throws SQLException;

* Reports whether
* the last column read had a value of SQL <code>NULL</code>.
* Note that you must first call one of the getter methods
* on a column to try to read its value and then call
* the method <code>wasNull</code> to see if the value read was
* SQL <code>NULL</code>.
*
* @return <code>true</code> if the last column value read was SQL
*         <code>NULL</code> and <code>false</code> otherwise
* @exception SQLException if a database access error occurs or this method is 
*            called on a closed result set

Building on some of the responds here, i'd like to add an alternative way. Creating a generic method using reflection, that can map any Stored Procedure response to a List. That is, a List of any type you wish, as long as the given type contains similarly named members to the Stored Procedure columns in the response. Ideally, i'd probably use Dapper for this - but here goes:

private static SqlConnection getConnectionString() // Should be gotten from config in secure storage.
        {
            SqlConnectionStringBuilder builder = new SqlConnectionStringBuilder();
            builder.DataSource = "it.hurts.when.IP";
            builder.UserID = "someDBUser";
            builder.Password = "someDBPassword";
            builder.InitialCatalog = "someDB";
            return new SqlConnection(builder.ConnectionString);
        }

        public static List<T> ExecuteSP<T>(string SPName, List<SqlParameter> Params)
        {
            try
            {
                DataTable dataTable = new DataTable();

                using (SqlConnection Connection = getConnectionString())
                {
                    // Open connection
                    Connection.Open();

                    // Create command from params / SP
                    SqlCommand cmd = new SqlCommand(SPName, Connection);

                    // Add parameters
                    cmd.Parameters.AddRange(Params.ToArray());
                    cmd.CommandType = CommandType.StoredProcedure;

                    // Make datatable for conversion
                    SqlDataAdapter da = new SqlDataAdapter(cmd);
                    da.Fill(dataTable);
                    da.Dispose();

                    // Close connection
                    Connection.Close();
                }

                // Convert to list of T
                var retVal = ConvertToList<T>(dataTable);

                Console.WriteLine("ConvertToList Exception: " + e.ToString());

1. Check for your configuration files by running the aforementioned command: sudo nginx -t.

2. Check for port conflicts. For instance, if apache2 (ps waux | grep apache2) or any other service is using the same ports configured for nginx (say port 80) the service will not start and will fail silently (err... the cousin of my friend had this problem...)

To access the entity body of a POST or PUT request (or any other HTTP method):

$entityBody = file_get_contents('php://input');

Also, the STDIN constant is an already-open stream to php://input, so you can alternatively do:

$entityBody = stream_get_contents(STDIN);

From the PHP manual entry on I/O streams^docs:

php://input is a read-only stream that allows you to read raw data from the request body. In the case of POST requests, it is preferable to use php://input instead of $HTTP_RAW_POST_DATA as it does not depend on special php.ini directives. Moreover, for those cases where $HTTP_RAW_POST_DATA is not populated by default, it is a potentially less memory intensive alternative to activating always_populate_raw_post_data. php://input is not available with enctype="multipart/form-data".

Specifically you'll want to note that the php://input stream, regardless of how you access it in a web SAPI, is not seekable. This means that it can only be read once. If you're working in an environment where large HTTP entity bodies are routinely uploaded you may wish to maintain the input in its stream form (rather than buffering it like the first example above).

To maintain the stream resource something like this can be helpful:

<?php

function detectRequestBody() {
    $rawInput = fopen('php://input', 'r');
    $tempStream = fopen('php://temp', 'r+');
    stream_copy_to_stream($rawInput, $tempStream);
    rewind($tempStream);

    return $tempStream;
}

php://temp allows you to manage memory consumption because it will transparently switch to filesystem storage after a certain amount of data is stored (2M by default). This size can be manipulated in the php.ini file or by appending /maxmemory:NN, where NN is the maximum amount of data to keep in memory before using a temporary file, in bytes.

Of course, unless you have a really good reason for seeking on the input stream, you shouldn't need this functionality in a web application. Reading the HTTP request entity body once is usually enough -- don't keep clients waiting all day while your app figures out what to do.

Note that php://input is not available for requests specifying a Content-Type: multipart/form-data header (enctype="multipart/form-data" in HTML forms). This results from PHP already having parsed the form data into the $_POST superglobal.

I tried @Joanna's method and tested on the following websites and it didn't work.

1. https://regex101.com/
2. https://www.regextester.com/
3. https://regexr.com/

I then modified it to and it worked.

/([\w-]+(?:\.[\w-]+)*)@((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)\S+

It is the equivalent to \n -> LF (Line Feed).

Sometimes it is used in HTML and JavaScript. Otherwise in .NET environments, use Environment.NewLine.

I think you want an additional projection that maps each group to a sorted-version of the group:

.Select(group => group.OrderByDescending(student => student.Grade))

It also appears like you might want another flattening operation after that which will give you a sequence of students instead of a sequence of groups:

.SelectMany(group => group)

You can always collapse both into a single SelectMany call that does the projection and flattening together.

EDIT: As Jon Skeet points out, there are certain inefficiencies in the overall query; the information gained from sorting each group is not being used in the ordering of the groups themselves. By moving the sorting of each group to come before the ordering of the groups themselves, the Max query can be dodged into a simpler First query.

If you want to produce output grouped by section, displaying only the top n records from each section something like this:

SECTION     SUBSECTION

deer        American Elk/Wapiti
deer        Chinese Water Deer
dog         Cocker Spaniel
dog         German Shephard
horse       Appaloosa
horse       Morgan

...then the following should work pretty generically with all SQL databases. If you want the top 10, just change the 2 to a 10 toward the end of the query.

select
    x1.section
    , x1.subsection
from example x1
where
    (
    select count(*)
    from example x2
    where x2.section = x1.section
    and x2.subsection <= x1.subsection
    ) <= 2
order by section, subsection;

To set up:

create table example ( id int, section varchar(25), subsection varchar(25) );

insert into example select 0, 'dog', 'Labrador Retriever';
insert into example select 1, 'deer', 'Whitetail';
insert into example select 2, 'horse', 'Morgan';
insert into example select 3, 'horse', 'Tarpan';
insert into example select 4, 'deer', 'Row';
insert into example select 5, 'horse', 'Appaloosa';
insert into example select 6, 'dog', 'German Shephard';
insert into example select 7, 'horse', 'Thoroughbred';
insert into example select 8, 'dog', 'Mutt';
insert into example select 9, 'horse', 'Welara Pony';
insert into example select 10, 'dog', 'Cocker Spaniel';
insert into example select 11, 'deer', 'American Elk/Wapiti';
insert into example select 12, 'horse', 'Shetland Pony';
insert into example select 13, 'deer', 'Chinese Water Deer';
insert into example select 14, 'deer', 'Fallow';

You can use a defaultdict for this.

from collections import defaultdict
d = defaultdict(list)
d['key'].append('mykey')

This is slightly more efficient than setdefault since you don't end up creating new lists that you don't end up using. Every call to setdefault is going to create a new list, even if the item already exists in the dictionary.

public static void main(String[] args) {
    String start = "THIS_IS_A_TEST";
    StringBuffer sb = new StringBuffer();
    for (String s : start.split("_")) {
        sb.append(Character.toUpperCase(s.charAt(0)));
        if (s.length() > 1) {
            sb.append(s.substring(1, s.length()).toLowerCase());
        }
    }
    System.out.println(sb);
}

It sounds like you are going to be storing the value that input field contains after the form is submitted, which means you are using a scripting language. I would use it instead of JavaScript as most scripting languages have better time/date formatting options. In PHP you could do something like this:

<input id="date" name="date" value="<?php echo date("M j, Y - g:i"); ?>"/>

Which would fill the field with "Jun 16, 2009 - 8:58"

Since there are no events available to signal when the socket is disconnected, you will have to poll it at a frequency that is acceptable to you.

Using this extension method, you can have a reliable method to detect if a socket is disconnected.

static class SocketExtensions
{
  public static bool IsConnected(this Socket socket)
  {
    try
    {
      return !(socket.Poll(1, SelectMode.SelectRead) && socket.Available == 0);
    }
    catch (SocketException) { return false; }
  }
}

Long.toString()

The following should work:

long myLong = 1234567890123L;
String myString = Long.toString(myLong);

You can only have one output path.

from the docs https://github.com/webpack/docs/wiki/configuration#output

Options affecting the output of the compilation. output options tell Webpack how to write the compiled files to disk. Note, that while there can be multiple entry points, only one output configuration is specified.

If you use any hashing ([hash] or [chunkhash]) make sure to have a consistent ordering of modules. Use the OccurenceOrderPlugin or recordsPath.

CASE is an expression - it returns a single scalar value (per row). It can't return a complex part of the parse tree of something else, like an ORDER BY clause of a SELECT statement.

It looks like you just need:

ORDER BY 
CASE WHEN TblList.PinRequestCount <> 0 THEN TblList.PinRequestCount END desc,
CASE WHEN TblList.HighCallAlertCount <> 0 THEN TblList.HighCallAlertCount END desc, 
Case WHEN TblList.HighAlertCount <> 0 THEN TblList.HighAlertCount END DESC,
CASE WHEN TblList.MediumCallAlertCount <> 0 THEN TblList.MediumCallAlertCount END DESC,
Case WHEN TblList.MediumAlertCount <> 0 THEN TblList.MediumAlertCount END DESC,
TblList.LastName ASC, TblList.FirstName ASC, TblList.MiddleName ASC

Or possibly:

ORDER BY 
CASE
   WHEN TblList.PinRequestCount <> 0 THEN TblList.PinRequestCount
   WHEN TblList.HighCallAlertCount <> 0 THEN TblList.HighCallAlertCount
   WHEN TblList.HighAlertCount <> 0 THEN TblList.HighAlertCount
   WHEN TblList.MediumCallAlertCount <> 0 THEN TblList.MediumCallAlertCount
   WHEN TblList.MediumAlertCount <> 0 THEN TblList.MediumAlertCount
END desc,
TblList.LastName ASC, TblList.FirstName ASC, TblList.MiddleName ASC

It's a little tricky to tell which of the above (or something else) is what you're looking for because you've a) not explained what actual sort order you're trying to achieve, and b) not supplied any sample data and expected results, from which we could attempt to deduce the actual sort order you're trying to achieve.

This may be the answer we're looking for:

ORDER BY 
CASE
   WHEN TblList.PinRequestCount <> 0 THEN 5
   WHEN TblList.HighCallAlertCount <> 0 THEN 4
   WHEN TblList.HighAlertCount <> 0 THEN 3
   WHEN TblList.MediumCallAlertCount <> 0 THEN 2
   WHEN TblList.MediumAlertCount <> 0 THEN 1
END desc,
CASE
   WHEN TblList.PinRequestCount <> 0 THEN TblList.PinRequestCount
   WHEN TblList.HighCallAlertCount <> 0 THEN TblList.HighCallAlertCount
   WHEN TblList.HighAlertCount <> 0 THEN TblList.HighAlertCount
   WHEN TblList.MediumCallAlertCount <> 0 THEN TblList.MediumCallAlertCount
   WHEN TblList.MediumAlertCount <> 0 THEN TblList.MediumAlertCount
END desc,
TblList.LastName ASC, TblList.FirstName ASC, TblList.MiddleName ASC

In this case you might want to use the functions np.hstack and np.vstack

arr = np.array([])
arr = np.hstack((arr, np.array([1,2,3])))
# arr is now [1,2,3]

arr = np.vstack((arr, np.array([4,5,6])))
# arr is now [[1,2,3],[4,5,6]]

You also can use the np.concatenate function.

According to the grammar in the CSP spec, you need to specify schemes as scheme:, not just scheme. So, you need to change the image source directive to:

img-src 'self' data:;

json is a built-in module, you don't need to install it with pip.

I had the same question and I finally found the answer:

You need to handle BOTH the SelectionChanged event and the DropDownClosed like this:

In XAML:

<ComboBox Name="cmbSelect" SelectionChanged="ComboBox_SelectionChanged" DropDownClosed="ComboBox_DropDownClosed">
    <ComboBoxItem>1</ComboBoxItem>
    <ComboBoxItem>2</ComboBoxItem>
    <ComboBoxItem>3</ComboBoxItem>
</ComboBox>

In C#:

private bool handle = true;
private void ComboBox_DropDownClosed(object sender, EventArgs e) {
  if(handle)Handle();
  handle = true;
}

private void ComboBox_SelectionChanged(object sender, SelectionChangedEventArgs e) {
  ComboBox cmb = sender as ComboBox;
  handle = !cmb.IsDropDownOpen;
  Handle();
}

private void Handle() {

check if if your artifact Y have packaging set to "jar". If you have defined it as "war" by error or copy paste, it will show this strange "was cached in the local repository, resolution will not be reattempted until the update interval of internal has elapsed or updates are forced". I would expect something like "artifact Y is war, jar type expected".

Just for the record, here is the difference between If and IIf:

IIf(condition, true-part, false-part):

• This is the old VB6/VBA Function
• The function always returns an Object type, so if you want to use the methods or properties of the chosen object, you have to re-cast it with DirectCast or CType or the Convert.* Functions to its original type
• Because of this, if true-part and false-part are of different types there is no matter, the result is just an object anyway

If(condition, true-part, false-part):

• This is the new VB.NET Function
• The result type is the type of the chosen part, true-part or false-part
• This doesn't work, if Strict Mode is switched on and the two parts are of different types. In Strict Mode they have to be of the same type, otherwise you will get an Exception
• If you really need to have two parts of different types, switch off Strict Mode (or use IIf)
• I didn't try so far if Strict Mode allows objects of different type but inherited from the same base or implementing the same Interface. The Microsoft documentation isn't quite helpful about this issue. Maybe somebody here knows it.

For example:

let myString = "Hello World"
let myMatch = myString.match(/H.*/)
console.log(myMatch)

Or

let myString = "Hello World"
let myVariable = "H"
let myReg = new RegExp(myVariable + ".*")
let myMatch = myString.match(myReg)
console.log(myMatch)

You can do this using the splat operator:

some_func(*params)

This causes the function to receive each list item as a separate parameter. There's a description here: http://docs.python.org/tutorial/controlflow.html#unpacking-argument-lists

Actually this is not a duplicate question. And this how i solve my problem after several times :

   int offset = DateTimeZone.forID("anytimezone").getOffset(new DateTime());

This is the way to get offset from desired timezone.

Let's return to our code, we were getting timestamp from a result set of query, and using it with timezone to create our datetime.

   DateTime dt = new DateTime(rs.getTimestamp("anytimestampcolumn"),
                         DateTimeZone.forID("anytimezone"));

Now we will add our offset to the datetime, and get the timestamp from it.

    dt = dt.plusMillis(offset);
    Timestamp ts = new Timestamp(dt.getMillis());

May be this is not the actual way to get it, but it solves my case. I hope it helps anyone who is stuck here.

You can simply add the two.

• if the Time part of your Date column is always zero
• and the Date part of your Time column is also always zero (base date: January 1, 1900)

Adding them returns the correct result.

SELECT Combined = MyDate + MyTime FROM MyTable

Rationale (kudos to ErikE/dnolan)

It works like this due to the way the date is stored as two 4-byte Integers with the left 4-bytes being the date and the right 4-bytes being the time. Its like doing $0001 0000 + $0000 0001 = $0001 0001

Edit regarding new SQL Server 2008 types

Date and Time are types introduced in SQL Server 2008. If you insist on adding, you can use Combined = CAST(MyDate AS DATETIME) + CAST(MyTime AS DATETIME)

Edit2 regarding loss of precision in SQL Server 2008 and up (kudos to Martin Smith)

Have a look at How to combine date and time to datetime2 in SQL Server? to prevent loss of precision using SQL Server 2008 and up.

Try with following:

public DataTable fillDataTable(string table)
    {
        string query = "SELECT * FROM dstut.dbo." +table;

        SqlConnection sqlConn = new SqlConnection(conSTR);
        sqlConn.Open();
        SqlCommand cmd = new SqlCommand(query, sqlConn);
        SqlDataAdapter da=new SqlDataAdapter(cmd);
        DataTable dt = new DataTable();
        da.Fill(dt);
        sqlConn.Close();
        return dt;
    }

Hope it is helpful.

This can have different reasons like:

• You are using an incorrect password
• The MySQL server got an error when trying to resolve the IP address of the client host to a name
• No privileges are granted to the user

You can try one of the following steps:

To reset the password for the remote user by:

SET PASSWORD FOR some_user@ip_addr_of_remote_client=PASSWORD('some_password');

To grant access to the user by:

GRANT SELECT, INSERT, UPDATE, DELETE, LOCK TABLES ON YourDB.* TO user@Host IDENTIFIED by 'password';

Hope this helps you, if not then you will have to go through the documentation

That would run simultaneously yes. what if you wanted to run two animations on the same element simultaneously ?

$(function () {
    $('#first').animate({ width: '200px' }, 200);
    $('#first').animate({ marginTop: '50px' }, 200);
});

This ends up queuing the animations. to get to run them simultaneously you would use only one line.

$(function () {
    $('#first').animate({ width: '200px', marginTop:'50px' }, 200);
});

Is there any other way to run two different animation on the same element simultaneously ?

I would add mnoGoSearch to the list. Extremely performant and flexible solution, which works as Google : indexer fetches data from multiple sites, You could use basic criterias, or invent Your own hooks to have maximal search quality. Also it could fetch the data directly from the database.

The solution is not so known today, but it feets maximum needs. You could compile and install it or on standalone server, or even on Your principal server, it doesn't need so much ressources as Solr, as it's written in C and runs perfectly even on small servers.

In the beginning You need to compile it Yourself, so it requires some knowledge. I made a tiny script for Debian, which could help. Any adjustments are welcome.

As You are using Django framework, You could use or PHP client in the middle, or find a solution in Python, I saw some articles.

And, of course mnoGoSearch is open source, GNU GPL.

Here is a class I use when writing services. I usually have an interactive screen that comes up when the service is not called. From there I use the class as needed. It allows for multiple named instances on the same machine -hence the InstanceID field

Sample Call

  IntegratedServiceInstaller Inst = new IntegratedServiceInstaller();
  Inst.Install("MySvc", "My Sample Service", "Service that executes something",
                    _InstanceID,
// System.ServiceProcess.ServiceAccount.LocalService,      // this is more secure, but only available in XP and above and WS-2003 and above
  System.ServiceProcess.ServiceAccount.LocalSystem,       // this is required for WS-2000
  System.ServiceProcess.ServiceStartMode.Automatic);
  if (controller == null)
  {
    controller = new System.ServiceProcess.ServiceController(String.Format("MySvc_{0}", _InstanceID), ".");
                }
                if (controller.Status == System.ServiceProcess.ServiceControllerStatus.Running)
                {
                    Start_Stop.Text = "Stop Service";
                    Start_Stop_Debugging.Enabled = false;
                }
                else
                {
                    Start_Stop.Text = "Start Service";
                    Start_Stop_Debugging.Enabled = true;

I found this by adapting some tutos. Thanks to google, and to all of you ;)

def findall(L, test):
    i=0
    indices = []
    while(True):
        try:
            # next value in list passing the test
            nextvalue = filter(test, L[i:])[0]

            # add index of this value in the index list,
            # by searching the value in L[i:] 
            indices.append(L.index(nextvalue, i))

            # iterate i, that is the next index from where to search
            i=indices[-1]+1
        #when there is no further "good value", filter returns [],
        # hence there is an out of range exeption
        except IndexError:
            return indices

A very simple use:

a = [0,0,2,1]
ind = findall(a, lambda x:x>0))

Functions are not allowed to have side-effects such as altering table contents.

Stored Procedures are.

If a function called a stored procedure, the function would become able to have side-effects.

So, sorry, but no, you can't call a stored procedure from a function.

please try below command : kubectl patch pod -p '{"metadata":{"finalizers":null}}'

If the children have FKs linking them to the parent, then you can use DELETE CASCADE on the parent.

e.g.

CREATE TABLE supplier 
( supplier_id numeric(10) not null, 
 supplier_name varchar2(50) not null, 
 contact_name varchar2(50),  
 CONSTRAINT supplier_pk PRIMARY KEY (supplier_id) 
); 



CREATE TABLE products 
( product_id numeric(10) not null, 
 supplier_id numeric(10) not null, 
 CONSTRAINT fk_supplier 
   FOREIGN KEY (supplier_id) 
  REFERENCES supplier(supplier_id) 
  ON DELETE CASCADE 
); 

Delete the supplier, and it will delate all products for that supplier

I would apply this rule to all input fields of type text, so it doesn't need to be duplicated later:

input[type=text]::-ms-clear { display: none; }

One can even get less specific by using just:

::-ms-clear { display: none; }

I have used the later even before adding this answer, but thought that most people would prefer to be more specific than that. Both solutions work fine.

I assume we are discussing division of integers.

Consider that I got two number 1502 and 30, and I wanted to calculate 1502/30. This is how we do this:

First we align 30 with 1501 at its most significant figure; 30 becomes 3000. And compare 1501 with 3000, 1501 contains 0 of 3000. Then we compare 1501 with 300, it contains 5 of 300, then compare (1501-5*300) with 30. At so at last we got 5*(10^1) = 50 as the result of this division.

Now convert both 1501 and 30 into binary digits. Then instead of multiplying 30 with (10^x) to align it with 1501, we multiplying (30) in 2 base with 2^n to align. And 2^n can be converted into left shift n positions.

Here is the code:

int divide(int a, int b){
    if (b != 0)
        return;

    //To check if a or b are negative.
    bool neg = false;
    if ((a>0 && b<0)||(a<0 && b>0))
        neg = true;

    //Convert to positive
    unsigned int new_a = (a < 0) ? -a : a;
    unsigned int new_b = (b < 0) ? -b : b;

    //Check the largest n such that b >= 2^n, and assign the n to n_pwr
    int n_pwr = 0;
    for (int i = 0; i < 32; i++)
    {
        if (((1 << i) & new_b) != 0)
            n_pwr = i;
    }

    //So that 'a' could only contain 2^(31-n_pwr) many b's,
    //start from here to try the result
    unsigned int res = 0;
    for (int i = 31 - n_pwr; i >= 0; i--){
        if ((new_b << i) <= new_a){
            res += (1 << i);
            new_a -= (new_b << i);
        }
    }

    return neg ? -res : res;
}

Didn't test it, but you get the idea.

Try this:

Update TableB Set
  Code = Coalesce(
    (Select Max(Value)
    From TableA 
    Where Id = b.Id), 123)
From TableB b

Not using the standard API, no. You can roll your own doing something like this:

class Duration {
    private final TimeUnit unit;
    private final long length;
    // ...
}

Or you can use Joda:

DateTime a = ..., b = ...;
Duration d = new Duration(a, b);

What you can do to resolve your conflict is

svn resolve --accept working -R <path>

where <path> is where you have your conflict (can be the root of your repo).

Explanations:

• resolve asks svn to resolve the conflict
• accept working specifies to keep your working files
• -R stands for recursive

Hope this helps.

EDIT:

To sum up what was said in the comments below:

• <path> should be the directory in conflict (C:\DevBranch\ in the case of the OP)
• it's likely that the origin of the conflict is
  • either the use of the svn switch command
  • or having checked the Switch working copy to new branch/tag option at branch creation
• more information about conflicts can be found in the dedicated section of Tortoise's documentation.
• to be able to run the command, you should have the CLI tools installed together with Tortoise:

You may find an answer with this example : errorbar_demo_features.py

"""
Demo of errorbar function with different ways of specifying error bars.

Errors can be specified as a constant value (as shown in `errorbar_demo.py`),
or as demonstrated in this example, they can be specified by an N x 1 or 2 x N,
where N is the number of data points.

N x 1:
    Error varies for each point, but the error values are symmetric (i.e. the
    lower and upper values are equal).

2 x N:
    Error varies for each point, and the lower and upper limits (in that order)
    are different (asymmetric case)

In addition, this example demonstrates how to use log scale with errorbar.
"""

The most important thing is add tzinfo when you define a datetime object.

from datetime import datetime, timezone
from tzinfo_examples import HOUR, Eastern
u0 = datetime(2016, 3, 13, 5, tzinfo=timezone.utc)
for i in range(4):
     u = u0 + i*HOUR
     t = u.astimezone(Eastern)
     print(u.time(), 'UTC =', t.time(), t.tzname())

A Static method, variable, block or nested class belongs to the entire class rather than an object.

A Method in Java is used to expose the behaviour of an Object / Class. Here, as the method is static (i.e, static method is used to represent the behaviour of a class only.) changing/ overriding the behaviour of entire class will violate the phenomenon of one of the fundamental pillar of Object oriented programming i.e, high cohesion. (remember a constructor is a special kind of method in Java.)

High Cohesion - One class should have only one role. For example: A car class should produce only car objects and not bike, trucks, planes etc. But the Car class may have some features(behaviour) that belongs to itself only.

Therefore, while designing the java programming language. The language designers thought to allow developers to keep some behaviours of a class to itself only by making a method static in nature.

The below piece code tries to override the static method, but will not encounter any compilation error.

public class Vehicle {
static int VIN;

public static int getVehileNumber() {
    return VIN;
}}

class Car extends Vehicle {
static int carNumber;

public static int getVehileNumber() {
    return carNumber;
}}

This is because, here we are not overriding a method but we are just re-declaring it. Java allows re-declaration of a method (static/non-static).

Removing the static keyword from getVehileNumber() method of Car class will result into compilation error, Since, we are trying to change the functionality of static method which belongs to Vehicle class only.

Also, If the getVehileNumber() is declared as final then the code will not compile, Since the final keyword restricts the programmer from re-declaring the method.

public static final int getVehileNumber() {
return VIN;     }

Overall, this is upto software designers for where to use the static methods. I personally prefer to use static methods to perform some actions without creating any instance of a class. Secondly, to hide the behaviour of a class from outside world.

AJAX isn't for downloading files. Pop up a new window with the download link as its address, or do document.location = ....

Well, it's fairly self-explanatory: you've run out of memory.

You may want to try starting it with more memory, using the -Xmx flag, e.g.

java -Xmx2048m [whatever you'd have written before]

This will use up to 2 gigs of memory.

See the non-standard options list for more details.

If your requirements are to have no duplicates, you should be using a HashSet.

HashSet.Add will return false when the item already exists (if that even matters to you).

As of MySQL 5.7.6, use ALTER USER

Example:

ALTER USER 'username' IDENTIFIED BY 'password';

Because:

• SET PASSWORD ... = PASSWORD('auth_string') syntax is deprecated as of MySQL 5.7.6 and will be removed in a future MySQL release.

• SET PASSWORD ... = 'auth_string' syntax is not deprecated, but ALTER USER is now the preferred statement for assigning passwords.

When they say "The bottom of the page" they don't literally mean the bottom: they mean just before the closing </body> tag. Place your scripts there and they will be loaded before the DOMReady event; place them afterwards and the DOM will be ready before they are loaded (because it's complete when the closing </html> tag is parsed), which as you have found will not work.

If you're wondering how I know that this is what they mean: I have worked at Yahoo! and we put our scripts just before the </body> tag :-)

EDIT: also, see T.J. Crowder's reply and make sure you have things in the correct order.

Typical usage might look like:

i=0
echo -e "hello1\nhello2\nhello3" | while read str ; do
    echo "$((++i)): $str"
done

and output

1: hello1
2: hello2
3: hello3

      {"label" : "1", "value" : 12},_x000D_
      {"label" : "1", "value" : 12},_x000D_
      {"label" : "1", "value" : 12},_x000D_
    ];_x000D_
    _x000D_
data = [...data, {"label" : "2", "value" : 14}] _x000D_
console.log(data)

For your case (i know it was in 2011), we can do it with map() & forEach() like below

var lab = ["1","2","3","4"];_x000D_
var val = [42,55,51,22];_x000D_
_x000D_
//Using forEach()_x000D_
var data = [];_x000D_
val.forEach((v,i) => _x000D_
   data= [...data, {"label": lab[i], "value":v}]_x000D_
)_x000D_
_x000D_
//Using map()_x000D_
var dataMap = val.map((v,i) => _x000D_
 ({"label": lab[i], "value":v})_x000D_
)_x000D_
_x000D_
console.log('data: ', data);_x000D_
console.log('dataMap : ', dataMap);

regarding Kevin answer to write in a folder tmp, it should be like this:

with open('./tmp/metadata.pdf', 'wb') as f:
    f.write(response.content)

he forgot . before the address and of-course your folder tmp should have been created already

@Skelly 's answer is correct. It won't let me add a comment (<50 rep)... but to answer your question on his answer: In the example he linked, if you add

col-xs-3 

class to each of the thumbnails, like this:

class="col-md-3 col-xs-3"

then it should stay the way you want it when sized down to phone width.

pow is built into the language(not part of the math library). The problem is that you haven't imported math.

Try this:

import math
math.sqrt(4)

may this post can solve your problem

Simply use Contains method. Note that it works based on the equality function Equals

bool alreadyExist = list.Contains(item);

This is how.

Valid:

...
render() {

  return (
    <p>
       {/* This is a comment, one line */}

       {// This is a block 
        // yoohoo
        // ...
       }

       {/* This is a block 
         yoohoo
         ...
         */
       }
    </p>
  )

}
...

Invalid:

...
render() {

  return (
    <p>
       {// This is not a comment! oops! }

       {//
        Invalid comment
       //}

One thing to watch out for in benchmarks (especially phpbench.com), is even though the numbers are sound, the tests are not. Alot of the tests on phpbench.com are doing things at are trivial and abuse PHP's ability to cache array lookups to skew benchmarks or in the case of iterating over an array doesn't actually test it in real world cases (no one writes empty for loops). I've done my own benchmarks that I've found are fairly reflective of the real world results and they always show the language's native iterating syntax foreach coming out on top (surprise, surprise).

//make a nicely random array
$aHash1 = range( 0, 999999 );
$aHash2 = range( 0, 999999 );
shuffle( $aHash1 );
shuffle( $aHash2 );
$aHash = array_combine( $aHash1, $aHash2 );


$start1 = microtime(true);
foreach($aHash as $key=>$val) $aHash[$key]++;
$end1 = microtime(true);

$start2 = microtime(true);
while(list($key) = each($aHash)) $aHash[$key]++;
$end2 = microtime(true);


$start3 = microtime(true);
$key = array_keys($aHash);
$size = sizeOf($key);
for ($i=0; $i<$size; $i++) $aHash[$key[$i]]++;
$end3 = microtime(true);

$start4 = microtime(true);
foreach($aHash as &$val) $val++;
$end4 = microtime(true);

echo "foreach ".($end1 - $start1)."\n"; //foreach 0.947947025299
echo "while ".($end2 - $start2)."\n"; //while 0.847212076187
echo "for ".($end3 - $start3)."\n"; //for 0.439476966858
echo "foreach ref ".($end4 - $start4)."\n"; //foreach ref 0.0886030197144

//For these tests we MUST do an array lookup,
//since that is normally the *point* of iteration
//i'm also calling noop on it so that PHP doesn't
//optimize out the loopup.
function noop( $value ) {}

//Create an array of increasing indexes, w/ random values
$bHash = range( 0, 999999 );
shuffle( $bHash );

$bstart1 = microtime(true);
for($i = 0; $i < 1000000; ++$i) noop( $bHash[$i] );
$bend1 = microtime(true);

$bstart2 = microtime(true);
$i = 0; while($i < 1000000) { noop( $bHash[$i] ); ++$i; }
$bend2 = microtime(true);


$bstart3 = microtime(true);
foreach( $bHash as $value ) { noop( $value ); }
$bend3 = microtime(true);

echo "for ".($bend1 - $bstart1)."\n"; //for 0.397135972977
echo "while ".($bend2 - $bstart2)."\n"; //while 0.364789962769
echo "foreach ".($bend3 - $bstart3)."\n"; //foreach 0.346374034882

its even simpler than that. Using HTML you can just add this metatag to your page (first thing on the page):

<meta http-equiv="X-UA-Compatible" content="IE=7" />

If you wanted to do it using.net, you just have to send your http request with that meta information in the header. This would require a page refresh to work though.

Also, you can look at a similar question here: Compatibility Mode in IE8 using VBScript

See this question: Converting data.frame to xts order.by requires an appropriate time-based object, which suggests looking at argument to order.by,

Currently acceptable classes include: ‘Date’, ‘POSIXct’, ‘timeDate’, as well as ‘yearmon’ and ‘yearqtr’ where the index values remain unique.

And further suggests an explicit conversion using order.by = as.POSIXct,

df$Date <- as.POSIXct(strptime(df$Date,format),tz="UTC")
xts(df[, -1], order.by=as.POSIXct(df$Date))

Where your format is assigned elswhere,

format <- "%m/%d/%Y" #see strptime for details

Despite Daniel Böhmer's working solution, Ohad Schneider offered a better solution in a comment:

If the file is usually ignored, and you force adding it - it can be accidentally ignored again in the future (like when the file is deleted, then a commit is made and the file is re-created.

You should just un-ignore it in the .gitignore file like that: Unignore subdirectories of ignored directories in Git

I have noticed that XMLSpy(at least 2011 version)needs a targetNameSpace defined if elementFormDefault="qualified" is used. Otherwise won't validate. And also won't generate xmls with namespace prefixes

After that you have to parse the results. Suppose results are in integers, then

int testint1 = Integer.parse(test1);

Similarly others should be parsed. Now the results should be checked for two higher marks in them, by using if statement After that take out the average.

It is not enough in case of PHP fpm. It was one more configuration file which can enable display_error. You should find www.conf. In my case it is in directory /etc/php/7.1/fpm/pool.d/

You should find php_flag[display_errors] = on and disable it, php_flag[display_errors] = off. This should solve the issue.

When you run into a problem where it cats all.txt into all.txt, You can try check all.txt is existing or not, if exists, remove

Like this:

[ -e $"all.txt" ] && rm $"all.txt"

You have to set a minWidth too, otherwise the cursor will disappear if the text is empty.

        <EditText
            android:id="@+id/et_card_view_list_name"
            android:layout_width="wrap_content"

            android:minWidth="30dp"
            android:layout_weight="1"
            android:inputType="text"
            android:text="Name"
            android:background="@android:color/transparent"
            />

If you are doing a presentation, and you don't care about anything lining up, Verdana is a good choice.

If you are going to distribute your presentation, use a font that you know is on everyone's machine, since using something else is going to cause the machine to fall back to one of the common fonts (like Arial or Times) anyway.

If you do care about things lining up, and are not distributing the presentation, consider Consolas:

It is highly legible, reminiscent of Verdana, and is monospaced. The color choices are, of course, a matter of taste.

You can use two s commands

There is a proposal open in GitHub for the C# language about having better support for raw string literals. One valid answer, is to encourage the C# team to add a new feature to the language (such as triple quote - like Python).

see https://github.com/dotnet/csharplang/discussions/89#discussioncomment-257343

I think the problem may be that you are not finding your element because of the "#" in your call to get it:

window.parent.document.getElementById('#target'); 

You only need the # if you are using jquery. Here it should be:

window.parent.document.getElementById('target'); 

With a FrameLayout you can place a text on top of an image view, the frame layout holding both an imageView and a textView.

If that's not enough and you want something more fancy like 'drawing' text, you need to draw text on a canvas - a sample is here: How to draw RTL text (Arabic) onto a Bitmap and have it ordered properly?

data.userID = "10";

The short answer to 2nd part of the question is simply that CString class doesn't provide a direct typecast conversion by design and what you are doing is kind of cheat.

A longer answer is the following:

The reason you can typcast CString to LPCTSTR is because CString provides this facility by overriding operator=. By design it provides conversion to only LPCTSTR pointer so the string value can't be modified with this pointer.

In other words, it simply doesn't provide an overload operator= to convert the CString into LPSTR for the same reason as above. They don't want to allow altering the string value this way.

So essentially, the trick is to use the operator CString provide and get this:

LPTSTR lptstr = (LPCTSTR) string; // CString provide this operator overload

Now LPTSTR can be further type casted to LPSTR :)

dispinfo.item.pszText = LPTSTR( lpfzfd); // accomplish the cheat :P

The correct way to get LPTSTR from 'CString' is this though (complete example):

CString str = _T("Hello");
LPTSTR lpstr = str.GetBuffer(str.GetAllocLength());
str.ReleaseBuffer(); // you must call this function if you change the string above with the pointer

Again because the GetBuffer() returns LPTSTR for that reason that now you can modify :)

You can use Oracle's SQL Developer tool to do that (My Oracle DB version is 11). While creating a table choose Advanced option and click on the Identity Column tab at the bottom and from there choose Column Sequence. This will generate a AUTO_INCREMENT column (Corresponding Trigger and Squence) for you.

Also you can use dirname(__DIR__, $level) for access any folding level without traversing

Did you turn on the "Allow less secure apps" on? go to this link

https://myaccount.google.com/security#connectedapps

Take a look at the Sign-in & security -> Apps with account access menu.

You must turn the option "Allow less secure apps" ON.

If is still doesn't work try one of these:

• Go to https://accounts.google.com/UnlockCaptcha , and click continue and unlock your account for access through other media/sites.

• Use double quote in your password: "your password"

And change your .env file

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
[email protected]
MAIL_PASSWORD=xxxxxx
MAIL_ENCRYPTION=tls

because the one's you have specified in the mail.php will only be used if the value is not available in the .env file.

Test e = static_cast<Test>(1);

Save the count as you go - and use validation to enforce it. I hacked this together - for keeping a count of unique votes and counts which keeps coming up!. But this time I have tested my suggestion! (notwithstanding cut/paste errors!).

The 'trick' here is to use the node priority to as the vote count...

The data is:

vote/$issueBeingVotedOn/user/$uniqueIdOfVoter = thisVotesCount, priority=thisVotesCount vote/$issueBeingVotedOn/count = 'user/'+$idOfLastVoter, priority=CountofLastVote

,"vote": {
  ".read" : true
  ,".write" : true
  ,"$issue" : {
    "user" : {
      "$user" : {
        ".validate" : "!data.exists() && 
             newData.val()==data.parent().parent().child('count').getPriority()+1 &&
             newData.val()==newData.GetPriority()" 

user can only vote once && count must be one higher than current count && data value must be same as priority.

      }
    }
    ,"count" : {
      ".validate" : "data.parent().child(newData.val()).val()==newData.getPriority() &&
             newData.getPriority()==data.getPriority()+1 "
    }

count (last voter really) - vote must exist and its count equal newcount, && newcount (priority) can only go up by one.

  }
}

Test script to add 10 votes by different users (for this example, id's faked, should user auth.uid in production). Count down by (i--) 10 to see validation fail.

<script src='https://cdn.firebase.com/v0/firebase.js'></script>
<script>
  window.fb = new Firebase('https:...vote/iss1/');
  window.fb.child('count').once('value', function (dss) {
    votes = dss.getPriority();
    for (var i=1;i<10;i++) vote(dss,i+votes);
  } );

function vote(dss,count)
{
  var user='user/zz' + count; // replace with auth.id or whatever
  window.fb.child(user).setWithPriority(count,count);
  window.fb.child('count').setWithPriority(user,count);
}
</script>

The 'risk' here is that a vote is cast, but the count not updated (haking or script failure). This is why the votes have a unique 'priority' - the script should really start by ensuring that there is no vote with priority higher than the current count, if there is it should complete that transaction before doing its own - get your clients to clean up for you :)

The count needs to be initialised with a priority before you start - forge doesn't let you do this, so a stub script is needed (before the validation is active!).

1. Edit POM.xml

Add the following property in pom.xml. Make sure you use the fully qualified class name (i.e. with package name) which contains the main method:

<properties>
        <exec.mainClass>fully-qualified-class-name</exec.mainClass>
</properties>

2. Run Command

Now from the terminal, trigger the following command:

mvn clean compile exec:java

NOTE You can pass further arguments via -Dexec.args="xxx" flag.

this points to the object in whose member function it is reffered, so it is optional.

Execute the following commands from command line...

sudo launchctl load -F /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist

sudo launchctl unload -F /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist

and then start the mysql server using

sudo /usr/local/mysql/support-files/mysql.server start

function clearSelection() {

        var sel = window.getSelection();
        sel.removeAllRanges();
    }
}

You can also apply these styles to the span for all non-IE browsers and IE10:

span.no_selection {
    user-select: none; /* standard syntax */
    -webkit-user-select: none; /* webkit (safari, chrome) browsers */
    -moz-user-select: none; /* mozilla browsers */
    -khtml-user-select: none; /* webkit (konqueror) browsers */
    -ms-user-select: none; /* IE10+ */
}

Try the zsh. It supports suffix alias, so you can define X in your .zshrc to be

alias -g X="| cut -d' ' -f2"

then you can do:

cat file X

You can take it one step further and define it for the nth column:

alias -g X2="| cut -d' ' -f2"
alias -g X1="| cut -d' ' -f1"
alias -g X3="| cut -d' ' -f3"

which will output the nth column of file "file". You can do this for grep output or less output, too. This is very handy and a killer feature of the zsh.

You can go one step further and define D to be:

alias -g D="|xargs rm"

Now you can type:

cat file X1 D

to delete all files mentioned in the first column of file "file".

If you know the bash, the zsh is not much of a change except for some new features.

each JSF component renders itself out to HTML and has complete control over what HTML it produces. There are many tricks that can be used by JSF, and exactly which of those tricks will be used depends on the JSF implementation you are using.

• Ensure that every from input has a totaly unique name, so that when the form gets submitted back to to component tree that rendered it, it is easy to tell where each component can read its value form.
• The JSF component can generate javascript that submitts back to the serer, the generated javascript knows where each component is bound too, because it was generated by the component.

• For things like hlink you can include binding information in the url as query params or as part of the url itself or as matrx parameters. for examples.

  http:..../somelink?componentId=123 would allow jsf to look in the component tree to see that link 123 was clicked. or it could e htp:..../jsf;LinkId=123

The easiest way to answer this question is to create a JSF page with only one link, then examine the html output it produces. That way you will know exactly how this happens using the version of JSF that you are using.

HTML:

<div id="something">... content ...</div>

CSS:

#something {
    position: absolute;
    height: 200px;
    width: 400px;
    margin: -100px 0 0 -200px;
    top: 50%;
    left: 50%;
}

The pattern must have delimiters. Delimiters can be a forward slash (/) or any non alphanumeric characters(#,$,*,...). Examples

$pattern = "/My name is '(.*)' and im fine/"; 
$pattern = "#My name is '(.*)' and im fine#";
$pattern = "@My name is '(.*)' and im fine@";  

Wrap your image with a span element with a black background.

.img-wrapper {
  display: inline-block;
  background: #000;
}

.item-fade {
  vertical-align: top;
  transition: opacity 0.3s;
  -webkit-transition: opacity 0.3s;
  opacity: 1;
}

.item-fade:hover {
  opacity: 0.2;
}

<span class="img-wrapper">
   <img class="item-fade" src="http://placehold.it/100x100/cf5" />
</span>

Well, me also I was struggling with this issue: this is how I solved it: apply table-layout: auto; to the <table> element.

See http://git.or.cz/gitwiki/GitTips, section "How to compare two local repositories" in "General".

In short you are using GIT_ALTERNATE_OBJECT_DIRECTORIES environment variable to have access to object database of the other repository, and using git rev-parse with --git-dir / GIT_DIR to convert symbolic name in other repository to SHA-1 identifier.

Modern version would look something like this (assuming that you are in 'repo_a'):

GIT_ALTERNATE_OBJECT_DIRECTORIES=../repo_b/.git/objects \
   git diff $(git --git-dir=../repo_b/.git rev-parse --verify HEAD) HEAD

where ../repo_b/.git is path to object database in repo_b (it would be repo_b.git if it were bare repository). Of course you can compare arbitrary versions, not only HEADs.

Note that if repo_a and repo_b are the same repository, it might make more sense to put both of them in the same repository, either using "git remote add -f ..." to create nickname(s) for repository for repeated updates, or obe off "git fetch ..."; as described in other responses.

There exist many open source projects that handle all the drawing of line charts for you with a couple of lines of code. Here's how you can draw a line chart from data in a couple text (CSV) file with the XChart library. Disclaimer: I'm the lead developer of the project.

In this example, two text files exist in ./CSV/CSVChartRows/. Notice that each row in the files represents a data point to be plotted and that each file represents a different series. series1 contains x, y, and error bar data, whereas series2 contains just x and y, data.

series1.csv

1,12,1.4
2,34,1.12
3,56,1.21
4,47,1.5

series2.csv

1,56
2,34
3,12
4,26

Source Code

public class CSVChartRows {

  public static void main(String[] args) throws Exception {

    // import chart from a folder containing CSV files
    XYChart chart = CSVImporter.getChartFromCSVDir("./CSV/CSVChartRows/", DataOrientation.Rows, 600, 400);

    // Show it
    new SwingWrapper(chart).displayChart();

replug the device, unlock it and accept the new key

Actually there is a way to do this. It has limitation (one), but is 100% standard, not deprecated (like xmp), and works.

And it's trivial. Here it is:

<div id="mydoc-src" style="display: none;">
LlNnlljn77fggggkk77csJJK8bbJBKJBkjjjjbbbJJLJLLJo
<!--
YOUR CODE HERE.
    <script src="WidgetsLib/all.js"></script>
    ^^ This is a text, no side effects trying to load it.
-->
LlNnlljn77fggggkk77csJJK8bbJBKJBkjjjjbbbJJLJLLJo
</div>

Please let me explain. First of all, ordinary HTML comment does the job, to prevent whole block be interpreted. You can easily add in it any tags, all of them will be ignored. Ignored from interpretation, but still available via innerHTML! So what is left, is to get the contents, and filter the preceding and trailing comment tokens.

Except (remember - the limitation) you can't put there HTML comments inside, since (at least in my Chrome) nesting of them is not supported, and very first '-->' will end the show.

Well, it is a nasty little limitation, but in certain cases it's not a problem at all, if your text is free of HTML comments. And, it's easier to escape one construct, then a whole bunch of them.

Now, what is that weird LlNnlljn77fggggkk77csJJK8bbJBKJBkjjjjbbbJJLJLLJo string? It's a random string, like a hash, unlikely to be used in the block, and used for? Here's the context, why I have used it. In my case, I took the contents of one DIV, then processed it with Showdown markdown, and then the output assigned into another div. The idea was, to write markdown inline in the HTML file, and just open in a browser and it would transform on the load on-the-fly. So, in my case, <!-- became transformed to <p><!--</p>, the comment properly escaped. It worked, but polluted the screen. So, to easily remove it with regex, the random string was used. Here's the code:

    var converter = new showdown.Converter();
    converter.setOption('simplifiedAutoLink', true);
    converter.setOption('tables', true);
    converter.setOption('tasklists', true);
    var src = document.getElementById("mydoc-src");
    var res = document.getElementById("mydoc-res");
    res.innerHTML = converter.makeHtml(src.innerHTML)
            .replace(/<p>.{0,10}LlNnlljn77fggggkk77csJJK8bbJBKJBkjjjjbbbJJLJLLJo.{0,10}<\/p>/g, "");
    src.innerHTML = '';

And it works.

If somebody is interested, this article is written using this technique. Feel free to download, and look inside the HTML file.

It depends what you are using it for. Is it user input? Then use <textarea>, and escape everything. In my case, and probably it's your case too, I simply used comments, and it does the job.

If you don't use markdown, and just want to get it as is from a tag, then it's even simpler:

<div id="mydoc-src" style="display: none;">
<!--
YOUR CODE HERE.
    <script src="WidgetsLib/all.js"></script>
    ^^ This is a text, no side effects trying to load it.
-->
</div>

and JavaScript code to get it:

    var src = document.getElementById("mydoc-src");
    var YOUR_CODE = src.innerHTML.replace(/(<!--|-->)/g, "");

Your format specifier is incorrect. From the printf() man page on my machine:

0 A zero '0' character indicating that zero-padding should be used rather than blank-padding. A '-' overrides a '0' if both are used;

Field Width: An optional digit string specifying a field width; if the output string has fewer characters than the field width it will be blank-padded on the left (or right, if the left-adjustment indicator has been given) to make up the field width (note that a leading zero is a flag, but an embedded zero is part of a field width);

Precision: An optional period, '.', followed by an optional digit string giving a precision which specifies the number of digits to appear after the decimal point, for e and f formats, or the maximum number of characters to be printed from a string; if the digit string is missing, the precision is treated as zero;

For your case, your format would be %09.3f:

#include <stdio.h>

int main(int argc, char **argv)
{
  printf("%09.3f\n", 4917.24);
  return 0;
}

Output:

$ make testapp
cc     testapp.c   -o testapp
$ ./testapp 
04917.240

Note that this answer is conditional on your embedded system having a printf() implementation that is standard-compliant for these details - many embedded environments do not have such an implementation.

UsernamePasswordAuthenticationFilter is only used for /login, and latter filters are not?

No, UsernamePasswordAuthenticationFilter extends AbstractAuthenticationProcessingFilter, and this contains a RequestMatcher, that means you can define your own processing url, this filter only handle the RequestMatcher matches the request url, the default processing url is /login.

Later filters can still handle the request, if the UsernamePasswordAuthenticationFilter executes chain.doFilter(request, response);.

More details about core fitlers

Does the form-login namespace element auto-configure these filters?

UsernamePasswordAuthenticationFilter is created by <form-login>, these are Standard Filter Aliases and Ordering

Does every request (authenticated or not) reach FilterSecurityInterceptor for non-login url?

It depends on whether the before fitlers are successful, but FilterSecurityInterceptor is the last fitler normally.

Does configuring two http elements create two springSecurityFitlerChains?

Yes, every fitlerChain has a RequestMatcher, if the RequestMatcher matches the request, the request will be handled by the fitlers in the fitler chain.

The default RequestMatcher matches all request if you don't config the pattern, or you can config the specific url (<http pattern="/rest/**").

If you want to konw more about the fitlers, I think you can check source code in spring security. doFilter(ServletRequest request, ServletResponse response, FilterChain filterChain)

Store the Thread-objects into some collection (like a List or a Set), then loop through the collection once the threads are started and call join() on the Threads.

I just want to expand on queen3's suggestion, applying the following does the trick:

editoptions: { 
              dataInit: function(element) { 
                          $(element).attr("readonly", "readonly"); 
                        } 
             }

Scenario #1:

• Field must be visible in the grid
• Field must be visible in the form
• Field must be read-only

Solution:

colModel:[
        {  name:'providerUserId',
               index:'providerUserId', 
               width:100,editable:true, 
               editrules:{required:true}, 
               editoptions:{ 
                            dataInit: function(element) { 
                                  jq(element).attr("readonly", "readonly"); 
                             } 
                           }
            },
],

The providerUserId is visible in the grid and visible when editing the form. But you cannot edit the contents.

Scenario #2:

• Field must not be visible in the grid
• Field must be visible in the form
• Field must be read-only

Solution:

colModel:[
           {name:'providerUserId',
            index:'providerUserId', 
            width:100,editable:true, 
            editrules:{
                         required:true, 
                         edithidden:true
                      },
            hidden:true, 
            editoptions:{ 
                  dataInit: function(element) {                     
                             jq(element).attr("readonly", "readonly"); 
                          } 
                     }
         },
        ]

Notice in both instances I'm using jq to reference jquery, instead of the usual $. In my HTML I have the following script to modify the variable used by jQuery:

<script type="text/javascript">
    var jq = jQuery.noConflict();
</script>

It depends on what you mean:

• As mentioned String.hashCode() gives you a 32 bit hash code.

• If you want (say) a 64-bit hashcode you can easily implement it yourself.

• If you want a cryptographic hash of a String, the Java crypto libraries include implementations of MD5, SHA-1 and so on. You'll typically need to turn the String into a byte array, and then feed that to the hash generator / digest generator. For example, see @Bryan Kemp's answer.

• If you want a guaranteed unique hash code, you are out of luck. Hashes and hash codes are non-unique.

A Java String of length N has 65536 ^ N possible states, and requires an integer with 16 * N bits to represent all possible values. If you write a hash function that produces integer with a smaller range (e.g. less than 16 * N bits), you will eventually find cases where more than one String hashes to the same integer; i.e. the hash codes cannot be unique. This is called the Pigeonhole Principle, and there is a straight forward mathematical proof. (You can't fight math and win!)

But if "probably unique" with a very small chance of non-uniqueness is acceptable, then crypto hashes are a good answer. The math will tell you how big (i.e. how many bits) the hash has to be to achieve a given (low enough) probability of non-uniqueness.

A (dirty) possible solution is by using patterns,

here is an example with an inside stroked triangle :

https://jsfiddle.net/qr3p7php/5/

<style>
#triangle1{
  fill: #0F0;
  fill-opacity: 0.3;
  stroke: #000;
  stroke-opacity: 0.5;
  stroke-width: 20;
}
#triangle2{
  stroke: #f00;
  stroke-opacity: 1;
  stroke-width: 1;
}    
</style>

<svg height="210" width="400" >
    <pattern id="fagl" patternUnits="objectBoundingBox" width="2" height="1" x="-50%">
        <path id="triangle1" d="M150 0 L75 200 L225 200 Z">
    </pattern>    
    <path id="triangle2" d="M150 0 L75 200 L225 200 Z" fill="url(#fagl)"/>
</svg>

I am new to Angular but have found this to solve my issue:

<i class="icon-download" ng-click="showDetails = ! showDetails" ng-class="{'icon-upload': showDetails}"></i>

This will conditionally apply a class based on a var. It starts off with a icon-download as a default, the using ng-class, I check the status of showDetails if true/false and apply class icon-upload. Its working great.

Hope it helps.

In case of excluding test component or test configuration, Spring Boot 1.4 introduced new testing annotations @TestComponent and @TestConfiguration.

Your regular expression should look like:

/^(?=.*\d)(?=.*[a-z])(?=.*[A-Z])[0-9a-zA-Z]{8,}$/

Here is an explanation:

/^
  (?=.*\d)          // should contain at least one digit
  (?=.*[a-z])       // should contain at least one lower case
  (?=.*[A-Z])       // should contain at least one upper case
  [a-zA-Z0-9]{8,}   // should contain at least 8 from the mentioned characters
$/

For Bootstrap:

<div class="navbar-fixed-bottom row-fluid">
  <div class="navbar-inner">
    <div class="container">
      Text
    </div>
  </div>
</div>

According to http://en.wikipedia.org/wiki/Maximum_segment_size, the default largest size for a IPV4 packet on a network is 536 octets (bytes of size 8 bits). See RFC 879

You are using the wrong iteration counter, replace inp.charAt(i) with inp.charAt(j).

For Angular 2+, in any modern browser having developper tools (F12) you can inspect the top level application tag.

If I understand you correctly, you're talking about doing a

svn merge -rn:n-1

to back out of an earlier commit, in which case, you're probably looking for

git revert

These solutions are working in case when target database is blank. In case when both databases already have some data you need something more complicated http://byalexblog.net/merge-sql-databases

If it's a list of constants then you can use Select Case as follows:

Dim Item$: Item = "A"

Select Case Item
  Case "A", "B", "C"
    ' If 'Item' is in the list then do something.
  Case Else
    ' Otherwise do something else.
End Select
