I hope the following sequence of code will help you:

Bitmap targetBitmap = Bitmap.createBitmap(targetWidth, targetHeight, config);
Canvas canvas = new Canvas(targetBitmap);
Matrix matrix = new Matrix();
matrix.setRotate(mRotation,source.getWidth()/2,source.getHeight()/2);
canvas.drawBitmap(source, matrix, new Paint());

If you check the following method from ~frameworks\base\graphics\java\android\graphics\Bitmap.java

public static Bitmap createBitmap(Bitmap source, int x, int y, int width, int height,
        Matrix m, boolean filter)

this would explain what it does with rotation and translate.

I know this is ancient however when dealing with finicky tools, uses, users or symptoms re: sid & service naming one can add a little flex to your tnsnames entries as like:

mySID, mySID.whereever.com =
(DESCRIPTION =
  (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = TCP)(HOST = myHostname)(PORT = 1521))
  )
  (CONNECT_DATA =
    (SERVICE_NAME = mySID.whereever.com)
    (SID = mySID)
    (SERVER = DEDICATED)
  )
)

I just thought I'd leave this here as it's mildly relevant to the question and can be helpful when attempting to weave around some less than clear idiosyncrasies of oracle networking.

int is a C# keyword and is unambiguous.

Most of the time it doesn't matter but two things that go against Int32:

• You need to have a "using System;" statement. using "int" requires no using statement.
• It is possible to define your own class called Int32 (which would be silly and confusing). int always means int.

The issue is because you have a bean of type SuggestionService created through @Component annotation and also through the XML config . As explained by JB Nizet, this will lead to the creation of a bean with name 'suggestionService' created via @Component and another with name 'SuggestionService' created through XML .

When you refer SuggestionService by @Autowired, in your controller, Spring autowires "by type" by default and find two beans of type 'SuggestionService'

You could do the following

1. Remove @Component from your Service and depend on mapping via XML - Easiest

2. Remove SuggestionService from XML and autowire the dependencies - use util:map to inject the indexSearchers map.

3. Use @Resource instead of @Autowired to pick the bean by its name .

    @Resource(name="suggestionService")
    private SuggestionService service;
   

or

    @Resource(name="SuggestionService")
    private SuggestionService service;

both should work.The third is a dirty fix and it's best to resolve the bean conflict through other ways.

1) Change your .net profile from Client profile to to .Net Framework 4.0 http://msdn.microsoft.com/en-us/library/bb398202.aspx

2) Check your Embed Interop Types flag

I only use MicrosoftAdvertising.Mobile and Microsoft.Advertising.Mobile.UI and I am served ads. The SDK should only add the DLLs not reference itself.

Note: You need to explicitly set width and height Make sure the phone dialer, and web browser capabilities are enabled

Followup note: Make sure that after you've removed the SDK DLL, that the xmlns references are not still pointing to it. The best route to take here is

1. Remove the XAML for the ad
2. Remove the xmlns declaration (usually at the top of the page, but sometimes will be declared in the ad itself)
3. Remove the bad DLL (the one ending in .SDK )
4. Do a Clean and then Build (clean out anything remaining from the DLL)
5. Add the xmlns reference (actual reference is below)
6. Add the ad to the page (example below)

Here is the xmlns reference:

xmlns:AdNamepace="clr-namespace:Microsoft.Advertising.Mobile.UI;assembly=Microsoft.Advertising.Mobile.UI" 

Then the ad itself:

<AdNamespace:AdControl x:Name="myAd" Height="80" Width="480"                    AdUnitId="yourAdUnitIdHere" ApplicationId="yourIdHere"/> 

Cors can be a pain in the ass, but with this simple code you are Cors ONLY!!!! to to specified method

@CrossOrigin(origins="*")// in this line add your url and thats is all for spring boot side
    @GetMapping("/some")
    public String index() {
        return "pawned cors!!!!";
    }

Like a charm in spring boot 2.0.2

In front-end JavaScript/HTML, you can load a binary file as an image, you do not have to convert to base64:

<img src="http://engci.nabisco.com/artifactory/repo/folder/my-image">

my-image is a binary image file. This will load just fine.

You can use the CultureInfo to get the month name. You can even get the short month name as well as other fun things.

I would suggestion you put these into extension methods, which will allow you to write less code later. However you can implement however you like.

Here is an example of how to do it using extension methods:

using System;
using System.Globalization;

class Program
{
    static void Main()
    {

        Console.WriteLine(DateTime.Now.ToMonthName());
        Console.WriteLine(DateTime.Now.ToShortMonthName());
        Console.Read();
    }
}

static class DateTimeExtensions
{
    public static string ToMonthName(this DateTime dateTime)
    {
        return CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(dateTime.Month);
    }

    public static string ToShortMonthName(this DateTime dateTime)
    {
        return CultureInfo.CurrentCulture.DateTimeFormat.GetAbbreviatedMonthName(dateTime.Month);
    }
}

Hope this helps!

To get that information in SQL Management Studio, right click on the database, then select Reports --> Standard Reports --> Disk Usage by Table.

-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=PORT_NUMBER

Here we just use a Socket Attaching Connector, which is enabled by default when the dt_socket transport is configured and the VM is running in the server debugging mode.

The second parameter in Substring is the length of the substring, not the end index.

You should probably include handling to check that it does indeed start with what you expect, end with what you expect, and is at least as long as you expect. And then if it doesn't match, you can either do something else or throw a meaningful error.

Here's some example code that validates that url contains your strings, that also is refactored a bit to make it easier to change the prefix/suffix to strip:

var prefix = "www.example.com/";
var suffix = ".jpg";
string url = "www.example.com/aaa/bbb.jpg";

if (url.StartsWith(prefix) && url.EndsWith(suffix) && url.Length >= (prefix.Length + suffix.Length))
{
    string newString = url.Substring(prefix.Length, url.Length - prefix.Length - suffix.Length);
    Console.WriteLine(newString);
}
else
    //handle invalid state

I'm the author of HPN-SSH and I was asked by a commenter here to weigh in. I'd like to start with a couple of background items. First off, it's important to keep in mind that SSHv2 is a multiplexed protocol - multiple channels over a single TCP connection. As such, the SSH channels are essentially unaware of the underlying flow control algorithm used by TCP. This means that SSHv2 has to implement its own flow control algorithm. The most common implementation basically reimplements sliding windows. The means that you have the SSH sliding window riding on top of the TCP sliding window. The end results is that the effective size of the receive buffer is the minimum of the receive buffers of the two sliding windows. Stock OpenSSH has a maximum receive buffer size of 2MB but this really ends up being closer to ~1.2MB. Most modern OSes have a buffer that can grow (using auto-tuning receive buffers) up to an effective size of 4MB. Why does this matter? If the receive buffer size is less than the bandwidth delay product (BDP) then you will never be able to fully fill the pipe regardless of how fast your system is.

This is complicated by the fact that SFTP adds another layer of flow control onto of the TCP and SSH flow controls. SFTP uses a concept of outstanding messages. Each message may be a command, a result of a command, or bulk data flow. The outstanding messages may be up to a specific datagram size. So you end up with what you might as well think of as yet another receive buffer. The size of this receive buffer is datagram size * maximum outstanding messages (both of which may be set on the command line). The default is 32k * 64 (2MB). So when using SFTP you have to make sure that the TCP receive buffer, the SSH receive buffer, and the SFTP receive buffer are all of sufficient size (without being too large or you can have over buffering problems in interactive sessions).

HPN-SSH directly addresses the SSH buffer problem by having a maximum buffer size of around 16MB. More importantly, the buffer dynamically grows to the proper size by polling the proc entry for the TCP connection's buffer size (basically poking a hole between layers 3 and 4). This avoids overbuffering in almost all situations. In SFTP we raise the maximum number of outstanding requests to 256. At least we should be doing that - it looks like that change didn't propagate as expected to the 6.3 patch set (though it is in 6.2. I'll fix that soon). There isn't a 6.4 version because 6.3 patches cleanly against 6.4 (which is a 1 line security fix from 6.3). You can get the patch set from sourceforge.

I know this sounds odd but right sizing the buffers was the single most important change in terms of performance. In spite of what many people think the encryption is not the real source of poor performance in most cases. You can prove this to yourself by transferring data to sources that are increasingly far away (in terms of RTT). You'll notice that the longer the RTT the lower the throughput. That clearly indicates that this is an RTT dependent performance problem.

Anyway, with this change I started seeing improvements of up to 2 orders of magnitude. If you understand TCP you'll understand why this made such a difference. It's not about the size of the datagram or the number of packets or anything like that. It's entire because in order to make efficient use of the network path you must have a receive buffer equal to the amount of data that can be in transit between the two hosts. This also means that you may not see any improvement whatsoever if the path isn't sufficiently fast and long enough. If the BDP is less than 1.2MB HPN-SSH may be of no value to you.

The parallelized AES-CTR cipher is a performance boost on systems with multiple cores if you need to have full encryption end to end. Usually I suggest people (or have control over both the server and client) to use the NONE cipher switch (encrypted authentication, bulk data passed in clear) as most data isn't all that sensitive. However, this only works in non-interactive sessions like SCP. It doesn't work in SFTP.

There are some other performance improvements as well but nothing as important as the right sizing of the buffers and the encryption work. When I get some free time I'll probably pipeline the HMAC process (currently the biggest drag on performance) and do some more minor optimization work.

So if HPN-SSH is so awesome why hasn't OpenSSH adopted it? That's a long story and people who know the OpenBSD team probably already know the answer. I understand many of their reasons - it's a big patch which would require additional work on their end (and they are a small team), they don't care as much about performance as security (though there is no security implications to HPN-SSH), etc etc etc. However, even though OpenSSH doesn't use HPN-SSH Facebook does. So do Google, Yahoo, Apple, most ever large research data center, NASA, NOAA, the government, the military, and most financial institutions. It's pretty well vetted at this point.

If anyone has any questions feel free to ask but I may not be keeping up to date on this forum. You can always send me mail via the HPN-SSH email address (google it).

The way to do this is to run the following command:

bundle update --source gem-name

for complette URL with protocol, servername and parameters:

 $base_url = ( isset($_SERVER['HTTPS']) && $_SERVER['HTTPS']=='on' ? 'https' : 'http' ) . '://' .  $_SERVER['HTTP_HOST'];
 $url = $base_url . $_SERVER["REQUEST_URI"];

You want to do the check for undefined first. If you do it the other way round, it will generate an error if the array is undefined.

if (array === undefined || array.length == 0) {
    // array empty or does not exist
}

Update

This answer is getting a fair amount of attention, so I'd like to point out that my original answer, more than anything else, addressed the wrong order of the conditions being evaluated in the question. In this sense, it fails to address several scenarios, such as null values, other types of objects with a length property, etc. It is also not very idiomatic JavaScript.

The foolproof approach
Taking some inspiration from the comments, below is what I currently consider to be the foolproof way to check whether an array is empty or does not exist. It also takes into account that the variable might not refer to an array, but to some other type of object with a length property.

if (!Array.isArray(array) || !array.length) {
  // array does not exist, is not an array, or is empty
  // ? do not attempt to process array
}

To break it down:

1. Array.isArray(), unsurprisingly, checks whether its argument is an array. This weeds out values like null, undefined and anything else that is not an array.
   Note that this will also eliminate array-like objects, such as the arguments object and DOM NodeList objects. Depending on your situation, this might not be the behavior you're after.

2. The array.length condition checks whether the variable's length property evaluates to a truthy value. Because the previous condition already established that we are indeed dealing with an array, more strict comparisons like array.length != 0 or array.length !== 0 are not required here.

The pragmatic approach
In a lot of cases, the above might seem like overkill. Maybe you're using a higher order language like TypeScript that does most of the type-checking for you at compile-time, or you really don't care whether the object is actually an array, or just array-like.

In those cases, I tend to go for the following, more idiomatic JavaScript:

if (!array || !array.length) {
    // array or array.length are falsy
    // ? do not attempt to process array
}

Or, more frequently, its inverse:

if (array && array.length) {
    // array and array.length are truthy
    // ? probably OK to process array
}

With the introduction of the optional chaining operator (Elvis operator) in ECMAScript 2020, this can be shortened even further:

if (!array?.length) {
    // array or array.length are falsy
    // ? do not attempt to process array
}

Or the opposite:

if (array?.length) {
    // array and array.length are truthy
    // ? probably OK to process array
}

For example, lets say we want to display only the first 10 items of an array, we could do this using the SlicePipe like so:

<ul>
     <li *ngFor="let item of items | slice:0:10">
      {{ item }}
     </li>
</ul>

You can also change the caracter set in your browser. Just for debug reasons.

It is very inefficient to store all values in memory, so the objects are reused and loaded one at a time. See this other SO question for a good explanation. Summary:

[...] when looping through the Iterable value list, each Object instance is re-used, so it only keeps one instance around at a given time.

The PackageInfo.sharedUserId field will show the user Id assigned in the manifest.

If you want two applications to have the same userId, so they can see each other's data and run in the same process, then assign them the same userId in the manifest:

android:sharedUserId="string"

The two packages with the same sharedUserId need to have the same signature too.

I would also recommend reading here for a nudge in the right direction.

Since all responses to this make use of the now long-deprecated abstract WebMvcConfigurer Adapter instead of the WebMvcInterface (as already noted by @sebdooe), here is a working minimal example for a SpringBoot (2.1.4) application with an Interceptor:

Minimal.java:

@SpringBootApplication
public class Minimal
{
    public static void main(String[] args)
    {
        SpringApplication.run(Minimal.class, args);
    }
}

MinimalController.java:

@RestController
@RequestMapping("/")
public class Controller
{
    @GetMapping("/")
    @ResponseBody
    public ResponseEntity<String> getMinimal()
    {
        System.out.println("MINIMAL: GETMINIMAL()");

        return new ResponseEntity<String>("returnstring", HttpStatus.OK);
    }
}

Config.java:

@Configuration
public class Config implements WebMvcConfigurer
{
    //@Autowired
    //MinimalInterceptor minimalInterceptor;

    @Override
    public void addInterceptors(InterceptorRegistry registry)
    {
        registry.addInterceptor(new MinimalInterceptor());
    }
}

MinimalInterceptor.java:

public class MinimalInterceptor extends HandlerInterceptorAdapter
{
    @Override
    public boolean preHandle(HttpServletRequest requestServlet, HttpServletResponse responseServlet, Object handler) throws Exception
    {
        System.out.println("MINIMAL: INTERCEPTOR PREHANDLE CALLED");

        return true;
    }

    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception
    {
        System.out.println("MINIMAL: INTERCEPTOR POSTHANDLE CALLED");
    }

    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception exception) throws Exception
    {
        System.out.println("MINIMAL: INTERCEPTOR AFTERCOMPLETION CALLED");
    }
}

works as advertised

The output will give you something like:

Some long answers here. The principle is very simple though. I submit the opening statement from wikipedia:

"Loose coupling describes a resilient relationship between two or more systems or organizations with some kind of exchange relationship.

Each end of the transaction makes its requirements explicit and makes few assumptions about the other end."

lapply(your_dataframe, class) gives you something like:

$tikr [1] "factor"

$Date [1] "Date"

$Open [1] "numeric"

$High [1] "numeric"

... etc.

Well, I'd have to agree with the "design" point... but you can probably use a Monitor to let one know when the other is past the critical section...

    public void foo() {
        // Do stuff!

        object syncLock = new object();
        lock (syncLock) {
            // Delayed call to bar() after x number of ms
            ThreadPool.QueueUserWorkItem(delegate {
                lock(syncLock) {
                    bar();
                }
            });

            // Do more Stuff
        } 
        // lock now released, bar can begin            
    }

I find very useful to understand how to organize code in Golang this chapter http://www.golang-book.com/11 of the book written by Caleb Doxsey

If you want to select only one of two nodes with union operator, you can use this solution: (//bookstore/book/title | //bookstore/city/zipcode/title)[1]

Reading quickly through the source it seems that you're not far off. The following link should help (I did something similar but for FTP). For a file send from server to client, you start off with a file instance and an array of bytes. You then read the File into the byte array and write the byte array to the OutputStream which corresponds with the InputStream on the client's side.

Edit: Here's a working ultra-minimalistic file sender and receiver. Make sure you understand what the code is doing on both sides.

Byte array of unknown length in java

Edit: The following could be used to fingerprint small files before and after transfer (use SHA if you feel it's necessary):

public static String md5String(File file) {
    try {
        InputStream fin = new FileInputStream(file);
        java.security.MessageDigest md5er = MessageDigest.getInstance("MD5");
        byte[] buffer = new byte[1024];
        int read;
        do {
            read = fin.read(buffer);
            if (read > 0) {
                md5er.update(buffer, 0, read);
            }
        } while (read != -1);
        fin.close();
        byte[] digest = md5er.digest();
        if (digest == null) {
            return null;
        }
        String strDigest = "0x";
        for (int i = 0; i < digest.length; i++) {
            strDigest += Integer.toString((digest[i] & 0xff)
                    + 0x100, 16).substring(1).toUpperCase();
        }
        return strDigest;
    } catch (Exception e) {
        return null;

This is what it worked for me. The tsconfig.json has an option noImplicitAny that it was set to true, I just simply set it to false and now I can access properties in objects using strings.

MySQL will assume the part before the equals references the columns named in the INSERT INTO clause, and the second part references the SELECT columns.

INSERT INTO lee(exp_id, created_by, location, animal, starttime, endtime, entct, 
                inact, inadur, inadist, 
                smlct, smldur, smldist, 
                larct, lardur, lardist, 
                emptyct, emptydur)
SELECT id, uid, t.location, t.animal, t.starttime, t.endtime, t.entct, 
       t.inact, t.inadur, t.inadist, 
       t.smlct, t.smldur, t.smldist, 
       t.larct, t.lardur, t.lardist, 
       t.emptyct, t.emptydur 
FROM tmp t WHERE uid=x
ON DUPLICATE KEY UPDATE entct=t.entct, inact=t.inact, ...

What type of sql database are using (MSSQL, Oracle etc)? I believe what you have written is correct.

You could also write the first query like this:

SELECT s.sid, s.name
FROM Supplier s
WHERE (SELECT COUNT(DISTINCT pr.jid)
       FROM Supplies su, Projects pr
       WHERE su.sid = s.sid 
           AND pr.jid = su.jid) >= 2

It's a little more readable, and less mind-bending than trying to do it with GROUP BY. Performance may differ though.

Try using batch file

1. Open notepad
2. type php -S localhost:8000
3. save file as .bat extension, server.bat
4. now click on server.bat file your server is ready on http://localhost:8000

Dependency

if you got error php not recognize any internal or external command then goto environment variable and edit path to php.exe "C:\wamp\bin\php\php5.4.3"

No need to use a macro. Supposing your first string is in A1.

=RIGHT(A1, 4)

Drag this down and you will get your four last characters.

Edit: To be sure, if you ever have sequences like 'ABC DEF' and want the last four LETTERS and not CHARACTERS you might want to use trimspaces()

=RIGHT(TRIMSPACES(A1), 4)

Edit: As per brettdj's suggestion, you may want to check that your string is actually 4-character long or more:

=IF(TRIMSPACES(A1)>=4, RIGHT(TRIMSPACES(A1), 4), TRIMSPACES(A1))

You could try adding an<hr>and styling that. Its a minimal markup change but seems to need less css so that might do the trick.

In addition to the above you can use the System.exit() to return an exit code which may be very usuefull specially if your calling the process automatically using the System.exit(code); this can help you determine for example if an error has occured during the run.

Aergistal's answer works, but I found that converting to mp4 can make some m3u8 videos broken. If you are stuck with this problem, try to convert them to mkv, and convert them to mp4 later.

I had the same Issue, I checked the php.net site. And found the right format.
This is my updated code.

$headers = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
$headers .= 'From:  ' . $fromName . ' <' . $fromEmail .'>' . " \r\n" .
            'Reply-To: '.  $fromEmail . "\r\n" .
            'X-Mailer: PHP/' . phpversion();

The \r\n should be in double quotes(") itself, the single quotes(') will not work.

It's good to know that

but also know that math.log takes an optional second argument which allows you to specify the base:

In [22]: import math

In [23]: math.log?
Type:       builtin_function_or_method
Base Class: <type 'builtin_function_or_method'>
String Form:    <built-in function log>
Namespace:  Interactive
Docstring:
    log(x[, base]) -> the logarithm of x to the given base.
    If the base not specified, returns the natural logarithm (base e) of x.


In [25]: math.log(8,2)
Out[25]: 3.0

You are accessing an object that is not defined.

The solution is check for null or undefined (to see whether the object exists) and only then iterate.

Applying the BoxCox transformation to data, without the need of any underlying model, can be done currently using the package geoR. Specifically, you can use the function boxcoxfit() for finding the best parameter and then predict the transformed variables using the function BCtransform().

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();

I believe this should solve your problem. I may be missing a few edge cases, please comment if you notice one.

You need a way to exclude previous substitutions from future patterns, which really means making outputs distinguishable, as well as excluding these outputs from your searches, and finally making outputs indistinguishable again. This is very similar to the quoting/escaping process, so I'll draw from it.

• s/\\/\\\\/g escapes all existing backslashes
• s/ab/\\b\\c/g substitutes raw ab for escaped bc
• s/bc/\\a\\b/g substitutes raw bc for escaped ab
• s/\\\(.\)/\1/g substitutes all escaped X for raw X

I have not accounted for backslashes in ab or bc, but intuitively, I would escape the search and replace terms the same way - \ now matches \\, and substituted \\ will appear as \.

Until now I have been using backslashes as the escape character, but it's not necessarily the best choice. Almost any character should work, but be careful with the characters that need escaping in your environment, sed, etc. depending on how you intend to use the results.

This is a solution that will work for .NET backends out of the box. I have taken the primary answer of this thread and updated it to fit our .NET needs.

function objectToQuerystring(params) {
var result = '';

    function convertJsonToQueryString(data, progress, name) {
        name = name || '';
        progress = progress || '';
        if (typeof data === 'object') {
            Object.keys(data).forEach(function (key) {
                var value = data[key];
                if (name == '') {
                    convertJsonToQueryString(value, progress, key);
                } else {
                    if (isNaN(parseInt(key))) {
                        convertJsonToQueryString(value, progress, name + '.' + key);
                    } else {
                        convertJsonToQueryString(value, progress, name + '[' + key+ ']');
                    }
                }
            })
        } else {
            result = result ? result.concat('&') : result.concat('?');
            result = result.concat(`${name}=${data}`);
        }
    }

    convertJsonToQueryString(params);
    return result;
}

This just requires a small change to my last answer:

my ($guid, $scheme, $star) = $line =~ m{
    The [ ] Scheme [ ] GUID: [ ]
    ([a-zA-Z0-9-]+)          #capture the guid
    [ ]
    \(  (.+)  \)             #capture the scheme 
    (?:
        [ ]
        ([*])                #capture the star 
    )?                       #if it exists
}x;

While searching this very question I discovered this example in the documentation.

QPushButton *quitButton = new QPushButton("Quit");
connect(quitButton, &QPushButton::clicked, &app, &QCoreApplication::quit, Qt::QueuedConnection);

Mutatis mutandis for your particular action of course.

Along with this note.

It's good practice to always connect signals to this slot using a QueuedConnection. If a signal connected (non-queued) to this slot is emitted before control enters the main event loop (such as before "int main" calls exec()), the slot has no effect and the application never exits. Using a queued connection ensures that the slot will not be invoked until after control enters the main event loop.

It's common to connect the QGuiApplication::lastWindowClosed() signal to quit()

You could also just pass an EventEmitter as Input. Not quite sure if this is best practice tho...

CategoryComponent.ts:

categoryIdEvent: EventEmitter<string> = new EventEmitter<>();

- OTHER CODE -

setCategoryId(id) {
 this.category.id = id;
 this.categoryIdEvent.emit(this.category.id);
}

CategoryComponent.html:

<video-list *ngIf="category" [categoryId]="categoryIdEvent"></video-list>

And in VideoListComponent.ts:

@Input() categoryIdEvent: EventEmitter<string>
....
ngOnInit() {
 this.categoryIdEvent.subscribe(newID => {
  this.categoryId = newID;
 }
}

If you have the to your project and the Copy Local flag is in true, the solution should be just the project. That copy the DLL to the bin folder.

Had a similar issue, it turned out the listening port printed was different from what it actually was. Typos in the request string or listening function might make the target server appear to not exist.

Clustered Index

A clustered index determine the physical order of DATA in a table.For this reason a table have only 1 clustered index.

• "dictionary" No need of any other Index, its already Index according to words

Nonclustered Index

A non clustered index is analogous to an index in a Book.The data is stored in one place. The index is storing in another place and the index have pointers to the storage location of the data.For this reason a table have more than 1 Nonclustered index.

• "Chemistry book" at staring there is a separate index to point Chapter location and At the "END" there is another Index pointing the common WORDS location

The most simple and the correct way is to use Record type Record<string, string>

const myVar : Record<string, string> = {
   key1: 'val1',
   key2: 'val2',
}

>>> a = [(1, u'abc'), (2, u'def')]
>>> [i[0] for i in a]
[1, 2]

For those with the same issue as @Ravi Bhanushali, here is a Swift 4 solution:

let storyboard = UIStoryboard(name: "Main", bundle: Bundle.main)

Mostly if you need a concurrent list it is inside a model object (as you should not use abstract data types like a list to represent a node in a application model graph) or it is part of a particular service, you can synchronize the access yourself.

class MyClass {
  List<MyType> myConcurrentList = new ArrayList<>();
  void myMethod() {
    synchronzied(myConcurrentList) {
      doSomethingWithList;
    }
  }
}

Often this is enough to get you going. If you need to iterate, iterate over a copy of the list not the list itself and only synchronize the part where you copy the list not while you are iterating over it.

Also when concurrently working on a list you usually do something more than just adding or removing or copying, meaning that the operation becomes meaningful enough to warrent its own method and the list becomes member of a special class representing just this particular list with thread safe behavior.

Even if I agree that a concurrent list implementation is needed and Vector / Collections.sychronizeList(list) do not do the trick as for sure you need something like compareAndAdd or compareAndRemove or get(..., ifAbsentDo), even if you have a ConcurrentList implementation developers often introduce bugs by not considering what is the true transaction when working with a concurrent lists (and maps).

These scenarios where the transactions are too small for what the intended purpose of the interaction with a concurrent ADT (abstract data type) always lead to me hide the list in a special class and synchronizing access to this class objects method using the synchronized on the method level. Its the only way to be sure that the transactions are correct.

I have seen too many bugs to do it any other way - at least if the code is important and handles something like money or security or guarantees some quality of service measures (e.g sending message at least once and only once).

Just use this this decrypter to decrypt your locally cached username & password.

By default, TortoiseSVN stores your cached credentials inside files in the %APPDATA%\Subversion\auth\svn.simple directory. The passwords are encrypted using the Windows Data Protection API, with a key tied to your user account. This tool reads the files and uses the API to decrypt your passwords

Use "selrow" to get the selected row Id

var myGrid = $('#myGridId');

var selectedRowId = myGrid.jqGrid("getGridParam", 'selrow');

and then use getRowData to get the selected row at index selectedRowId.

var selectedRowData = myGrid.getRowData(selectedRowId);

If the multiselect is set to true on jqGrid, then use "selarrrow" to get list of selected rows:

var selectedRowIds = myGrid.jqGrid("getGridParam", 'selarrrow');

Use loop to iterate the list of selected rows:

var selectedRowData;

for(selectedRowIndex = 0; selectedRowIndex < selectedRowIds .length; selectedRowIds ++) {

   selectedRowData = myGrid.getRowData(selectedRowIds[selectedRowIndex]);

}

Use dispatch group

dispatchGroup.enter()
FirstOperation(completion: { _ in
    dispatchGroup.leave()
})
dispatchGroup.enter()
SecondOperation(completion: { _ in
    dispatchGroup.leave()
})
dispatchGroup.wait() // Waits here on this thread until the two operations complete executing.

Or is || in C#.

You may have a look at this.

The following link seems to work fine -

<a href="whatsapp://send?text=Hello World!&phone=+9198********1">Ping me on WhatsApp</a>

It opens the contact in WhatsApp app, along with the message 'Hello World!' prepopulated in the input text box.

(Tested this with google chrome on an android phone.)

Try this..

Dim S As String
S = "RAJAN"
Dim answer As Char

Even I got the same error, but I solved it, I had used many list in my work so I just restarted my kernel (meaning if you are using a notebook such as Jupyter or Google Colab you can just restart and again run all the cells, by doing this your problem will be solved and the error vanishes.

Thank you.

Thread.sleep(1000);

is the worse: being a static wait, it will make test script slower.

driver.manage().timeouts.implicitlyWait(10,TimeUnit.SECONDS);

this is a dynamic wait

• it is valid till webdriver existence or has a scope till driver lifetime
• we can implicit wait also.

Finally, what I suggest is

WebDriverWait wait = new WebDriverWait(driver,20);
wait.until(ExpectedConditions.<different canned or predefined conditions are there>);

with some predefined conditions:

isAlertPresent();
elementToBeSelected();
visibilityOfElementLocated();
visibilityOfAllElementLocatedBy();
frameToBeAvailableAndSwitchToIt();

• It is also dynamic wait
• in this the wait will only be in seconds
• we have to use explicit wait for a particular web element on which we want to use.

Personally I would go with:

DataTable tbl = Gridview1.DataSource as DataTable;

This would allow you to test for null as this results in either DataTable object or null. Casting it as a DataTable using (DataTable)Gridview1.DataSource would cause a crashing error in case the DataSource is actually a DataSet or even some kind of collection.

There is also someone who managed to modify CR for VS.NET 2010 to install on 2012, using MS ORCA in this thread: http://scn.sap.com/thread/3235515 . I couldn't get it to work myself, though.

I'm also running XP SP2, and this works perfectly (from the command line...):

start control schedtasks

There are a couple of options there. The sample code is in Java, but a port to other languages should be straightforward.

Java:

WebElement myElement = driver.findElement(By.id("myDiv"));
WebElement parent = (WebElement) ((JavascriptExecutor) driver).executeScript(
                                   "return arguments[0].parentNode;", myElement);

XPath:

WebElement myElement = driver.findElement(By.id("myDiv"));
WebElement parent = myElement.findElement(By.xpath("./.."));

Obtaining the driver from the WebElement

Note: As you can see, for the JavaScript version you'll need the driver. If you don't have direct access to it, you can retrieve it from the WebElement using:

WebDriver driver = ((WrapsDriver) myElement).getWrappedDriver();

How about:

firstNonNull = FluentIterable.from(
    Lists.newArrayList( a, b, c, ... ) )
        .firstMatch( Predicates.notNull() )
            .or( someKnownNonNullDefault );

Java ArrayList conveniently allows null entries and this expression is consistent regardless of the number of objects to be considered. (In this form, all the objects considered need to be of the same type.)

Basically, you need to include the Wordpress loop in your search.php template to loop through the search results and show them as part of the template.

                </header><!-- .page-header -->

                <?php shape_content_nav( 'nav-above' ); ?>

                <?php /* Start the Loop */ ?>
                <?php while ( have_posts() ) : the_post(); ?>

                    <?php get_template_part( 'content', 'search' ); ?>

                <?php endwhile; ?>

                <?php shape_content_nav( 'nav-below' ); ?>

            <?php else : ?>

                <?php get_template_part( 'no-results', 'search' ); ?>

Normal money conversions will preserve individual pennies:

SELECT convert(varchar(30), moneyfield, 1)

The last parameter decides what the output format looks like:

0 (default) No commas every three digits to the left of the decimal point, and two digits to the right of the decimal point; for example, 4235.98.

1 Commas every three digits to the left of the decimal point, and two digits to the right of the decimal point; for example, 3,510.92.

2 No commas every three digits to the left of the decimal point, and four digits to the right of the decimal point; for example, 4235.9819.

If you want to truncate the pennies, and count in pounds, you can use rounding to the nearest pound, floor to the lowest whole pound, or ceiling to round up the pounds:

SELECT convert(int, round(moneyfield, 0))
SELECT convert(int, floor(moneyfield))
SELECT convert(int, ceiling(moneyfield))

The error implies that this subquery is returning more than 1 row:

(Select Supplier_Item.Price from Supplier_Item,orderdetails,Supplier where Supplier_Item.SKU=OrderDetails.Sku and Supplier_Item.SupplierId=Supplier.SupplierID )

You probably don't want to include the orderdetails and supplier tables in the subquery, because you want to reference the values selected from those tables in the outer query. So I think you want the subquery to be simply:

(Select Supplier_Item.Price from Supplier_Item where Supplier_Item.SKU=OrderDetails.Sku and Supplier_Item.SupplierId=Supplier.SupplierID )

I suggest you read up on correlated vs. non-correlated subqueries.

I had a similar problem, you gotta make sure you have:

1. oracle instant client
2. cx_Oracle binary( from SourceForge )
3. Python IMPORTANT: Make sure they are ALL either 64-bit or 32-bit, mixing is gonna cause problems

Most of the answers are/were valid. The new JAVA API modification for Date handling made sure that some earlier ambiguity in java date handling is reduced.

You will get a deprecated message for similar calls.

new Date() // deprecated

The above call had the developer to assume that a new Date object will give the Date object with current timestamp. This behavior is not consistent across other Java API classes.

The new way of doing this is using the Calendar Instance.

new SimpleDateFormat("yyyy-MM-dd").format(Calendar.getInstance().getTime()

Here too the naming convention is not perfect but this is much organised. For a person like me who has a hard time mugging up things but would never forget something if it sounds/appears logical, this is a good approach.

This is more synonymous to real life

1. We get a Calendar object and we look for the time in it. ( you must be wondering no body gets time from a Calendar, that is why I said it is not perfect.But that is a different topic altogether)
2. Then we want the date in a simple Text format so we use a SimpleDateFormat utility class which helps us in formatting the Date from Step 1. I have used yyyy, MM ,dd as parameters in the format. Supported date format parameters

One more way to do this is using Joda time API

new DateTime().toString("yyyy-MM-dd")

or the much obvious

new DateTime(Calendar.getInstance().getTime()).toString("yyyy-MM-dd")

both will return the same result.

$update = \DB::table('student') ->where('id', $data['id']) ->limit(1) ->update( [ 'name' => $data['name'], 'address' => $data['address'], 'email' => $data['email'], 'contactno' => $data['contactno'] ]); 

Try this:

<li onclick="getPaging(this.id)" id="1">1</li>
<li onclick="getPaging(this.id)" id="2">2</li>


function getPaging(str)
{
    $("#loading-content").load("dataSearch.php?"+str, hideLoader);
}

Here is a simple one

this.$children[indexOfComponent].childsMethodName();

(function(){
    var i = 0;
    function stop(){
        clearTimeout(i);
    }

    function start(){
        i = setTimeout( timed, 1000 );
    }

    function timed(){
       document.getElementById("input").value++;
       start();
    }

    window.stop = stop;
    window.start = start;
})()

If you use EXIT_SUCCESS, your code will be more portable.

I researched the issue of screen readers and tables a few years ago and came up with information that contradicts what most developers believe:

http://www.webaim.org/techniques/tables/

"You will probably hear some accessibility advocates say that layout tables are a bad idea, and that CSS layout techniques ought to be used instead. There is truth in what they say, but, to be honest, using tables for layout is not the worst thing that you could do in terms of accessibility. People with all kinds of disabilities can easily access tables, as long as the tables are designed with accessibility in mind. "

Laravel Server Requirements mention that BCMath, Ctype, JSON, Mbstring, OpenSSL, PDO, Tokenizer, and XML extensions are required. Most of the extensions are installed and enabled by default.

You can run the following command in Ubuntu to make sure the extensions are installed.

If you need some es6 improvements not supported by Typescript, you can target es6 in your tsconfig and use Babel to convert your files in es5.

Use the variables "$1", "$2", "$3" and so on to access arguments. To access all of them you can use "$@", or to get the count of arguments $# (might be useful to check for too few or too many arguments).

Even icfantv's answer to this question is already perfect, I still have more findings in my test.

As a server socket in listening status, if it only in listening status, and even it accepts request and getting data from the client side, but without any data sending action. We still could restart the server at once after it's stopped. But if any data sending action happens in the server side to the client, the same service(same port) restart will have this error: (Address already in use).

I think this is caused by the TCP/IP design principles. When the server send the data back to client, it must ensure the data sending succeed, in order to do this, the OS(Linux) need monitor the connection even the server application closed this socket. But I still believe kernel socket designer could improve this issue.

Publish / Subscribe With jQuery

June 17th, 2008

With a view to writing a jQuery UI integrated with the offline functionality of Google Gears i’ve been toying with some code to poll for network connection status using jQuery.

The Network Detection Object

The basic premise is very simple. We create an instance of a network detection object which will poll a URL at regular intervals. Should these HTTP requests fail we can assume that network connectivity has been lost, or the server is simply unreachable at the current time.

$.networkDetection = function(url,interval){
    var url = url;
    var interval = interval;
    online = false;
    this.StartPolling = function(){
        this.StopPolling();
        this.timer = setInterval(poll, interval);
    };
    this.StopPolling = function(){
        clearInterval(this.timer);
    };
    this.setPollInterval= function(i) {
        interval = i;
    };
    this.getOnlineStatus = function(){
        return online;
    };
    function poll() {
        $.ajax({
            type: "POST",
            url: url,
            dataType: "text",
            error: function(){
                online = false;
                $(document).trigger('status.networkDetection',[false]);
            },
            success: function(){
                online = true;
                $(document).trigger('status.networkDetection',[true]);
            }
        });
    };
};

You can view the demo here. Set your browser to work offline and see what happens…. no, it’s not very exciting.

Trigger and Bind

What is exciting though (or at least what is exciting me) is the method by which the status gets relayed through the application. I’ve stumbled upon a largely un-discussed method of implementing a pub/sub system using jQuery’s trigger and bind methods.

The demo code is more obtuse than it need to be. The network detection object publishes ’status ‘events to the document which actively listens for them and in turn publishes ‘notify’ events to all subscribers (more on those later). The reasoning behind this is that in a real world application there would probably be some more logic controlling when and how the ‘notify’ events are published.

$(document).bind("status.networkDetection", function(e, status){
    // subscribers can be namespaced with multiple classes
    subscribers = $('.subscriber.networkDetection');
    // publish notify.networkDetection even to subscribers
    subscribers.trigger("notify.networkDetection", [status])
    /*
    other logic based on network connectivity could go here
    use google gears offline storage etc
    maybe trigger some other events
    */
});

Because of jQuery’s DOM centric approach events are published to (triggered on) DOM elements. This can be the window or document object for general events or you can generate a jQuery object using a selector. The approach i’ve taken with the demo is to create an almost namespaced approach to defining subscribers.

DOM elements which are to be subscribers are classed simply with “subscriber” and “networkDetection”. We can then publish events only to these elements (of which there is only one in the demo) by triggering a notify event on $(“.subscriber.networkDetection”)

The #notifier div which is part of the .subscriber.networkDetection group of subscribers then has an anonymous function bound to it, effectively acting as a listener.

$('#notifier').bind("notify.networkDetection",function(e, online){
    // the following simply demonstrates
    notifier = $(this);
    if(online){
        if (!notifier.hasClass("online")){
            $(this)
                .addClass("online")
                .removeClass("offline")
                .text("ONLINE");
        }
    }else{
        if (!notifier.hasClass("offline")){
            $(this)
                .addClass("offline")
                .removeClass("online")
                .text("OFFLINE");
        }
    };
});

So, there you go. It’s all pretty verbose and my example isn’t at all exciting. It also doesn’t showcase anything interesting you could do with these methods, but if anyone’s at all interested to dig through the source feel free. All the code is inline in the head of the demo page

Assuming you have already downloaded Jdk 1.8. You have to make sure your eclipse version supports Jdk 1.8. Click on "Help" tab and then select "Check for Updates". Try again.

Please create a custom TextView and use it :

public class CustomTextView extends TextView {

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

    @Override
    public void setText(CharSequence text, BufferType type) {
        if (text.length() > 0) {
            text = String.valueOf(text.charAt(0)).toUpperCase() + text.subSequence(1, text.length());
        }
        super.setText(text, type);
    }
}

Option 1 allows you to initialize const members. This cannot be done with option 2 (as they are assigned to, not initialized).

Why must const members be intialized in the constructor initializer rather than in its body?

Guard your cast with instanceof

String myString;
if (object instanceof String) {
  myString = (String) object;
}

I Recommend you implement INotifyPropertyChanged and change your databinding code to this:

this.textBox.DataBindings.Add("Text",
                                this.Food,
                                "Name",
                                false,
                                DataSourceUpdateMode.OnPropertyChanged);

That'll fix it.

Note that the default DataSourceUpdateMode is OnValidation, so if you don't specify OnPropertyChanged, the model object won't be updated until after your validations have occurred.

How about this?

JSONObject jsonObject = new JSONObject           (YOUR_JSON_STRING);
JSONObject ipinfo     = jsonObject.getJSONObject ("ipinfo");
String     ip_address = ipinfo.getString         ("ip_address");
JSONObject location   = ipinfo.getJSONObject     ("Location");
String     latitude   = location.getString       ("latitude");
System.out.println (latitude);

This sample code using "org.json.JSONObject"

std::string a = "Hello ";
std::string b = "World ";
std::string c = a;
c.append(b);

Easy way to make a bash script log to syslog. The script output is available both through /var/log/syslog and through stderr. syslog will add useful metadata, including timestamps.

Add this line at the top:

exec &> >(logger -t myscript -s)

Alternatively, send the log to a separate file:

exec &> >(ts |tee -a /tmp/myscript.output >&2 )

This requires moreutils (for the ts command, which adds timestamps).

You can increment like below but you need to check for existence so that a NullPointerException is not thrown

if(!map.containsKey(key)) {
 p.put(key,1);
}
else {
 p.put(key, map.getKey()+1);
}

I found the following solution pretty effective if you need to comment a lot of nested HTML + PHP code.

Wrap all the content in this:

<?php
    if(false){
?>

Here goes your PHP + HTML code

<?php
    }
?>

A wildcard * can be translated as .* or .*? regex pattern.

You might need to use a singleline mode to match newline symbols, and in this case, you can use (?s) as part of the regex pattern.

You can set it for the whole or part of the pattern:

X* = > @"X(?s:.*)"
*X = > @"(?s:.*)X"
*X* = > @"(?s).*X.*"
*X*YZ* = > @"(?s).*X.*YZ.*"
X*YZ*P = > @"(?s:X.*YZ.*P)"

=IIF(Fields!Column.Value = "Approved", "Green", "No Color")

You can do a column transformation by using apply

Define a clean function to remove the dollar and commas and convert your data to float.

def clean(x):
    x = x.replace("$", "").replace(",", "").replace(" ", "")
    return float(x)

Next, call it on your column like this.

data['Revenue'] = data['Revenue'].apply(clean)

Just put your globals in the file you are importing.

Python 3

import openpyxl as xl

wb = xl.load_workbook("Sample.xlsx", enumerate)

#the 2 lines under do the same. 
sheet = wb.get_sheet_by_name('sheet') 
sheet = wb.worksheets[0]

row_count = sheet.max_row
column_count = sheet.max_column

#this works fore me.

You can use like the following

string result = null;
object value = cmd.ExecuteScalar();
 if (value != null)
 {
    result = value.ToString();
 }     
 conn.Close();
return result;

Not really, in the standard. Some implementations have a nonstandard itoa() function, and you could look up Boost's lexical_cast, but if you stick to the standard it's pretty much a choice between stringstream and sprintf() (snprintf() if you've got it).

How about this?

fscanf(file,"%d %d %d %d %d %d %d",&line1_1,&line1_2, &line1_3, &line2_1, &line2_2, &line3_1, &line3_2); 

In this case spaces in fscanf match multiple occurrences of any whitespace until the next token in found.

This, for example, will make files ending in .variables and .overrides being treated just like any other LESS file. In terms of code coloring, in terms of (auto) formatting. Define in user settings or project settings, as you like.

(Semantic UI uses these weird extensions, in case you wonder)

Many tricks work, but the Ajax request split the file name at 19 characters? Look at the output of the ajax request to see that:

The file name is okay to go into the href attribute, but the $(this).attr("href") use the text of the <a href='full/file/name' > Split file name </a>

So the $(data).find("a:contains(.jpg)") is not able to detect the extension.

I hope this is useful

Depends on what you mean by better. This works if your goal is removal of redundancy.

s='foo'
string='%s bar baz %s bar baz %s bar baz' % (3*(s,))

You can specify the orientation of an activity in the manifest. See here.

<activity android:allowTaskReparenting=["true" | "false"]
...
          android:screenOrientation=["unspecified" | "user" | "behind" |
                                     "landscape" | "portrait" |
                                     "sensor" | "nosensor"]
...
                                       "adjustResize", "adjustPan"] >  

If you want to check if some string is present in another string, use something like String.contains

If you want to check if some pattern is present in a string, append and prepend the pattern with '.*'. The result will accept strings that contain the pattern.

Example: Suppose you have some regex a(b|c) that checks if a string matches ab or ac
.*(a(b|c)).* will check if a string contains a ab or ac.

A disadvantage of this method is that it will not give you the location of the match.

It seems in the 2 years since this was asked, the other browsers have caught up (at least on Windows... not sure about others). You can set a "title" attribute on the option tag:

<option value="" title="Tooltip">Some option</option>

This worked in Chrome 20, IE 9 (and its 8 & 7 modes), Firefox 3.6, RockMelt 16 (Chromium based) all on Windows 7

@Andrew and @CZFox

I had the same bug and found the cause to be that parameter one is in fact: http://www.example.com?param1 and not param1 which is what one would expect.

By removing all characters before and including the question mark fixes this problem. So in essence the HttpUtility.ParseQueryString function only requires a valid query string parameter containing only characters after the question mark as in:

HttpUtility.ParseQueryString ( "param1=good&param2=bad" )

My workaround:

string RawUrl = "http://www.example.com?param1=good&param2=bad";
int index = RawUrl.IndexOf ( "?" );
if ( index > 0 )
    RawUrl = RawUrl.Substring ( index ).Remove ( 0, 1 );

Uri myUri = new Uri( RawUrl, UriKind.RelativeOrAbsolute);
string param1 = HttpUtility.ParseQueryString( myUri.Query ).Get( "param1" );`

As Alex says, it works very well. The only tricky part is to remember to make any changes in the cmake files, rather than from within Visual Studio. So on all platforms, the workflow is similar to if you'd used plain old makefiles.

But it's fairly easy to work with, and I've had no issues with cmake generating invalid files or anything like that, so I wouldn't worry too much.

Because on Unix, usually, the current directory is not in $PATH.

When you type a command the shell looks up a list of directories, as specified by the PATH variable. The current directory is not in that list.

The reason for not having the current directory on that list is security.

Let's say you're root and go into another user's directory and type sl instead of ls. If the current directory is in PATH, the shell will try to execute the sl program in that directory (since there is no other sl program). That sl program might be malicious.

It works with ./ because POSIX specifies that a command name that contain a / will be used as a filename directly, suppressing a search in $PATH. You could have used full path for the exact same effect, but ./ is shorter and easier to write.

EDIT

That sl part was just an example. The directories in PATH are searched sequentially and when a match is made that program is executed. So, depending on how PATH looks, typing a normal command may or may not be enough to run the program in the current directory.

Logically speaking Rohit's solution should have worked, but it didn't. I think SQL Management Studio messed up when trying to optimize this.

But by modifying the string before comparing them I was able to get the right results. This worked for me:

SELECT [ExternalId]
FROM [EquipmentSerialsMaster] where LOWER('0'+[ExternalId]) COLLATE Latin1_General_CS_AS != '0'+[ExternalId]

Simplest way is to use the dot operator in place of source, which is the sh equivalent of the bash source command:

Instead of:

RUN source /usr/local/bin/virtualenvwrapper.sh

Use:

RUN . /usr/local/bin/virtualenvwrapper.sh

try this it work out for me perfectly go to project and right click on your java file at the right corner, go to properties, go to run, go to browse, and then select Main class. now you can run your program again.

Try this.

Copy an Array :

const myCopiedArray  = Object.assign([], myArray);

Copy an object :

const myCopiedObject = Object.assign({}, myObject);

Yes, you need to have the header Access-Control-Allow-Origin: http://domain.com:3000 or Access-Control-Allow-Origin: * on both the OPTIONS response and the POST response. You should include the header Access-Control-Allow-Credentials: true on the POST response as well.

Your OPTIONS response should also include the header Access-Control-Allow-Headers: origin, content-type, accept to match the requested header.

java -verbose:class HelloWorld might help you understand which classes are being loaded.

Also, as mentioned before, remember to call the full qualified name (i.e. include package).

Please use !statusCheck.equals("success") instead of !=.

Here are more details.

The answers listed here which guide you to use SOAPHandler are fully correct. The benefit of that approach is that it will work with any JAX-WS implementation, as SOAPHandler is part of the JAX-WS specification. However, the problem with SOAPHandler is that it implicitly attempts to represent the whole XML message in memory. This can lead to huge memory usage. Various implementations of JAX-WS have added their own workarounds for this. If you work with large requests or large responses, then you need to look into one of the proprietary approaches.

Since you ask about "the one included in JDK 1.5 or better" I'll answer with respect to what is formally known as JAX-WS RI (aka Metro) which is what is included with the JDK.

JAX-WS RI has a specific solution for this which is very efficient in terms of memory usage.

See https://javaee.github.io/metro/doc/user-guide/ch02.html#efficient-handlers-in-jax-ws-ri. Unfortunately that link is now broken but you can find it on WayBack Machine. I'll give the highlights below:

The Metro folks back in 2007 introduced an additional handler type, MessageHandler<MessageHandlerContext>, which is proprietary to Metro. It is far more efficient than SOAPHandler<SOAPMessageContext> as it doesn't try to do in-memory DOM representation.

Here's the crucial text from the original blog article:

MessageHandler:

Utilizing the extensible Handler framework provided by JAX-WS Specification and the better Message abstraction in RI, we introduced a new handler called MessageHandler to extend your Web Service applications. MessageHandler is similar to SOAPHandler, except that implementations of it gets access to MessageHandlerContext (an extension of MessageContext). Through MessageHandlerContext one can access the Message and process it using the Message API. As I put in the title of the blog, this handler lets you work on Message, which provides efficient ways to access/process the message not just a DOM based message. The programming model of the handlers is same and the Message handlers can be mixed with standard Logical and SOAP handlers. I have added a sample in JAX-WS RI 2.1.3 showing the use of MessageHandler to log messages and here is a snippet from the sample:

public class LoggingHandler implements MessageHandler<MessageHandlerContext> {
    public boolean handleMessage(MessageHandlerContext mhc) {
        Message m = mhc.getMessage().copy();
        XMLStreamWriter writer = XMLStreamWriterFactory.create(System.out);
        try {
            m.writeTo(writer);
        } catch (XMLStreamException e) {
            e.printStackTrace();
            return false;
        }
        return true;
    }

    public boolean handleFault(MessageHandlerContext mhc) {
        ..... 
        return true;
    }

    public void close(MessageContext messageContext) {    }

    public Set getHeaders() {
        return null;
    }
}

(end quote from 2007 blog post)

Needless to say your custom Handler, LoggingHandler in the example, needs to be added to your Handler Chain to have any effect. This is the same as adding any other Handler, so you can look in the other answers on this page for how to do that.

You can find a full example in the Metro GitHub repo.

$("td:contains('c')").html("new");

or, more precisely $("#table_headers td:contains('c')").html("new");

and maybe for reuse you could create a function to call

function ReplaceCellContent(find, replace)
{
    $("#table_headers td:contains('" + find + "')").html(replace);
}

Be nice if there was a Javascript API version. That way can integrate w/ other AJAX apps or browser extensions/gadgets/widgets.

Right now, current APIs restrict to web app technologies that support Java, .NET, or Python, more for server side, unless may use Google Web Toolkit to translate Java code to Javascript.

Here is some code that will return the installed .NET details:

Generally

Your pkl file is, in fact, a serialized pickle file, which means it has been dumped using Python's pickle module.

To un-pickle the data you can:

import pickle


with open('serialized.pkl', 'rb') as f:
    data = pickle.load(f)

For the MNIST data set

Note gzip is only needed if the file is compressed:

import gzip
import pickle


with gzip.open('mnist.pkl.gz', 'rb') as f:
    train_set, valid_set, test_set = pickle.load(f)

Where each set can be further divided (i.e. for the training set):

train_x, train_y = train_set

Those would be the inputs (digits) and outputs (labels) of your sets.

If you want to display the digits:

import matplotlib.cm as cm
import matplotlib.pyplot as plt


plt.imshow(train_x[0].reshape((28, 28)), cmap=cm.Greys_r)
plt.show()

The other alternative would be to look at the original data:

http://yann.lecun.com/exdb/mnist/

But that will be harder, as you'll need to create a program to read the binary data in those files. So I recommend you to use Python, and load the data with pickle. As you've seen, it's very easy. ;-)

from sklearn import metrics              
import numpy as np
print(np.sqrt(metrics.mean_squared_error(y_test,y_predict)))

Google is my friend and it showed me this page:

Looks like something is messed up with your MySQL installation. The mysql.user table should definitely exist. Try running the command below on your server to create the tables in the database called mysql:

mysql_install_db

If that doesn't work, maybe the permissions on your MySQL data directory are messed up. Look at a "known good" installation as a reference for what the permissions should be.

You could also try re-installing MySQL completely.

Is using System.Threading.Timer mandatory?

If not, System.Timers.Timer has handy Start() and Stop() methods (and an AutoReset property you can set to false, so that the Stop() is not needed and you simply call Start() after executing).

This is one of the way to add google site search to websites:

<form action="https://www.google.com/search" class="searchform" method="get" name="searchform" target="_blank">_x000D_
<input name="sitesearch" type="hidden" value="example.com">_x000D_
<input autocomplete="on" class="form-control search" name="q" placeholder="Search in example.com" required="required"  type="text">_x000D_
<button class="button" type="submit">Search</button>_x000D_
</form>

wstring myString = L"Hello $$ this is an example. By $$.";
wstring search = L"$$";
wstring replace = L"Tom";
for (int i = myString.find(search); i >= 0; i = myString.find(search))
    myString.replace(i, search.size(), replace);

LIKE should work in sqlite:

require(sqldf)
df <- data.frame(name = c('bob','robert','peter'),id=c(1,2,3))
sqldf("select * from df where name LIKE '%er%'")
    name id
1 robert  2
2  peter  3

I know this is an older post but Bootstrap is still alive and kicking!

Slightly different to @Eduardo's post, I had to modify:

#myCarousel.carousel.slide {
    width: 100%; 
    max-width: 400px; !important
}

When I only modified .carousel-inner {}, the actual image was fixed size but the left/right controls were displaying incorrectly off to the side of the div.

Don't double click Project.xcodeproj to start your xcode project. Instead, close your project and open the xcworkspace.

File -> Close Workspace

File -> Open -> Search your project folder for Project.xcworkspace

All my errors are gone.

try using

View view_instance = (View)findViewById(R.id.nutrition_bar_filled);
view_instance.setWidth(10);

use Layoutparams to do so where you can set width and height like below.

LayoutParams lp = new LayoutParams(10,LayoutParams.wrap_content);
View_instance.setLayoutParams(lp);

I added the ISAPI/CGI paths for .Net 4. Which didn't fix the issue. So I then ran a repair on the .Net V4 (Client and Extended) installation. Which asked for a reboot. This fixed it for me.

Python has a built-in datatype for an unordered collection of (hashable) things, called a set. If you convert both lists to sets, the comparison will be unordered.

set(x) == set(y)

Documentation on set

EDIT: @mdwhatcott points out that you want to check for duplicates. set ignores these, so you need a similar data structure that also keeps track of the number of items in each list. This is called a multiset; the best approximation in the standard library is a collections.Counter:

>>> import collections
>>> compare = lambda x, y: collections.Counter(x) == collections.Counter(y)
>>> 
>>> compare([1,2,3], [1,2,3,3])
False
>>> compare([1,2,3], [1,2,3])
True
>>> compare([1,2,3,3], [1,2,2,3])
False
>>> 

What other guys done , in other post is a game of content, what i did is a game of linkedlist, it reverse the LinkedList's member not reverse of a Value of members.

Public LinkedList reverse(LinkedList List)
{
       if(List == null)
               return null;
       if(List.next() == null)
              return List;
       LinkedList temp = this.reverse( List.next() );
       return temp.setNext( List );
}

Just u can do single line .it will be remove element from array

$array=array_diff($array,['strawberry']);

updated() should be what you're looking for:

Called after a data change causes the virtual DOM to be re-rendered and patched.

The component’s DOM will have been updated when this hook is called, so you can perform DOM-dependent operations here.

Non-empty arrays

• var data0 = new int[3]

• var data1 = new int[3] { 1, 2, 3 }

• var data2 = new int[] { 1, 2, 3 }

• var data3 = new[] { 1, 2, 3 }

• var data4 = { 1, 2, 3 } is not compilable. Use int[] data5 = { 1, 2, 3 } instead.

Empty arrays

• var data6 = new int[0]
• var data7 = new int[] { }

• var data8 = new [] { } and int[] data9 = new [] { } are not compilable.

• var data10 = { } is not compilable. Use int[] data11 = { } instead.

As an argument of a method

Only expressions that can be assigned with the var keyword can be passed as arguments.

• Foo(new int[2])
• Foo(new int[2] { 1, 2 })
• Foo(new int[] { 1, 2 })
• Foo(new[] { 1, 2 })
• Foo({ 1, 2 }) is not compilable
• Foo(new int[0])
• Foo(new int[] { })
• Foo({}) is not compilable

Here is an API which was written to smooth over the nasty browser cookie "API"

http://code.google.com/p/cookies/

PATH: Answered long ago, however, it maybe more helpful to think of -p as "Path" (easier to remember), as in this causes mkdir to create every part of the path that isn't already there.

mkdir -p /usr/bin/comm/diff/er/fence

if /usr/bin/comm already exists, it acts like: mkdir /usr/bin/comm/diff mkdir /usr/bin/comm/diff/er mkdir /usr/bin/comm/diff/er/fence

As you can see, it saves you a bit of typing, and thinking, since you don't have to figure out what's already there and what isn't.

I know this is really old post but here is a simple solution to work with dynamic type in c#.

1. can use simple reflection to enumerate direct properties
2. or can use the object extention method
3. or use GetAsOrDefault<int> method to get a new strongly typed object with value if exists or default if not exists.

public static class DynamicHelper
{
    private static void Test( )
    {
        dynamic myobj = new
                        {
                            myInt = 1,
                            myArray = new[ ]
                                      {
                                          1, 2.3
                                      },
                            myDict = new
                                     {
                                         myInt = 1
                                     }
                        };

        var myIntOrZero = myobj.GetAsOrDefault< int >( ( Func< int > )( ( ) => myobj.noExist ) );
        int? myNullableInt = GetAs< int >( myobj, ( Func< int > )( ( ) => myobj.myInt ) );

        if( default( int ) != myIntOrZero )
            Console.WriteLine( $"myInt: '{myIntOrZero}'" );

        if( default( int? ) != myNullableInt )
            Console.WriteLine( $"myInt: '{myNullableInt}'" );

        if( DoesPropertyExist( myobj, "myInt" ) )
            Console.WriteLine( $"myInt exists and it is: '{( int )myobj.myInt}'" );
    }

    public static bool DoesPropertyExist( dynamic dyn, string property )
    {
        var t = ( Type )dyn.GetType( );
        var props = t.GetProperties( );
        return props.Any( p => p.Name.Equals( property ) );
    }

    public static object GetAs< T >( dynamic obj, Func< T > lookup )
    {
        try
        {
            var val = lookup( );
            return ( T )val;
        }
        catch( RuntimeBinderException ) { }

        return null;
    }

    public static T GetAsOrDefault< T >( this object obj, Func< T > test )
    {
        try
        {
            var val = test( );
            return ( T )val;
        }
        catch( RuntimeBinderException ) { }

        return default( T );
    }
}

You are trying to load a XIB named DetailViewController, but no such XIB exists or it's not member of your current target.

Using JSON.decode for this comes with significant drawbacks that you must be aware of:

• You must wrap the string in double quotes
• Many characters are not supported and must be escaped themselves. For example, passing any of the following to JSON.decode (after wrapping them in double quotes) will error even though these are all valid: \\n, \n, \\0, a"a
• It does not support hexadecimal escapes: \\x45
• It does not support Unicode code point sequences: \\u{045}

There are other caveats as well. Essentially, using JSON.decode for this purpose is a hack and doesn't work the way you might always expect. You should stick with using the JSON library to handle JSON, not for string operations.

I recently ran into this issue myself and wanted a robust decoder, so I ended up writing one myself. It's complete and thoroughly tested and is available here: https://github.com/iansan5653/unraw. It mimics the JavaScript standard as closely as possible.

Explanation:

The source is about 250 lines so I won't include it all here, but essentially it uses the following Regex to find all escape sequences and then parses them using parseInt(string, 16) to decode the base-16 numbers and then String.fromCodePoint(number) to get the corresponding character:

/\\(?:(\\)|x([\s\S]{0,2})|u(\{[^}]*\}?)|u([\s\S]{4})\\u([^{][\s\S]{0,3})|u([\s\S]{0,4})|([0-3]?[0-7]{1,2})|([\s\S])|$)/g

Commented (NOTE: This regex matches all escape sequences, including invalid ones. If the string would throw an error in JS, it throws an error in my library [ie, '\x!!' will error]):

/
\\ # All escape sequences start with a backslash
(?: # Starts a group of 'or' statements
(\\) # If a second backslash is encountered, stop there (it's an escaped slash)
| # or
x([\s\S]{0,2}) # Match valid hexadecimal sequences
| # or
u(\{[^}]*\}?) # Match valid code point sequences
| # or
u([\s\S]{4})\\u([^{][\s\S]{0,3}) # Match surrogate code points which get parsed together
| # or
u([\s\S]{0,4}) # Match non-surrogate Unicode sequences
| # or
([0-3]?[0-7]{1,2}) # Match deprecated octal sequences
| # or
([\s\S]) # Match anything else ('.' doesn't match newlines)
| # or
$ # Match the end of the string
) # End the group of 'or' statements
/g # Match as many instances as there are

Example

Using that library:

import unraw from "unraw";

let step1 = unraw('http\\u00253A\\u00252F\\u00252Fexample.com');
// yields "http%3A%2F%2Fexample.com"
// Then you can use decodeURIComponent to further decode it:
let step2 = decodeURIComponent(step1);
// yields http://example.com

Whenever one has a dictionary where the values are integers, the Counter data structure is often a better choice to represent the data than a dictionary.

If you already have a dictionary, a counter can easily be formed by:

c = Counter(d['123'])

as an example from your data.

The most_common function allows easy access to descending order of the items in the counter

The more complete writeup on the Counter data structure is at https://docs.python.org/2/library/collections.html

I realize this question is ancient and there is an accepted and an alternate answer. I also realize that my answer will only answer half of the question, but for anyone wanting to round to the nearest minute and still have a datetime compatible value using only a single function:

CAST(YourValueHere as smalldatetime);

For hours or seconds, use Jeff Ogata's answer (the accepted answer) above.

You can do it in just one line:

DateTime::createFromFormat('!m', $salary->month)->format('F'); //April

First convert the numeric value then add the 'S':

 select convert(varchar(10),StandardCost) +'S'
 from DimProduct where ProductKey = 212

I'm new with Android and the project appcompat_v7 always be created when I create new Android application project makes me so uncomfortable.

This is just a walk around. Choose Project Properties -> Android then at Library box just remove appcompat_v7_x and add appcompat_v7. Now you can delete appcompat_v7_x.

Uncheck Create Activity in create project wizard doesn't work, because when creating activity by wizard the appcompat_v7_x appear again. My ADT's version is v22.6.2-1085508.
I'm sorry if my English is bad.

Just use "Key" and "Value"

I ran into this same problem pulling some data from a sqlite3 database with python. The above answers didn't work for me (not sure why), but this did: line = line.decode('ascii', 'ignore') However, my goal was deleting the \xa0s, rather than replacing them with spaces.

I got this from this super-helpful unicode tutorial by Ned Batchelder.

I haven't had any problems with this code:

private bool IsValidPath(string path, bool exactPath = true)
{
    bool isValid = true;

    try
    {
        string fullPath = Path.GetFullPath(path);

        if (exactPath)
        {
            string root = Path.GetPathRoot(path);
            isValid = string.IsNullOrEmpty(root.Trim(new char[] { '\\', '/' })) == false;
        }
        else
        {
            isValid = Path.IsPathRooted(path);
        }
    }
    catch(Exception ex)
    {
        isValid = false;
    }

    return isValid;
}

For example these would return false:

IsValidPath("C:/abc*d");
IsValidPath("C:/abc?d");
IsValidPath("C:/abc\"d");
IsValidPath("C:/abc<d");
IsValidPath("C:/abc>d");
IsValidPath("C:/abc|d");
IsValidPath("C:/abc:d");
IsValidPath("");
IsValidPath("./abc");
IsValidPath("/abc");
IsValidPath("abc");
IsValidPath("abc", false);

And these would return true:

IsValidPath(@"C:\\abc");
IsValidPath(@"F:\FILES\");
IsValidPath(@"C:\\abc.docx\\defg.docx");
IsValidPath(@"C:/abc/defg");
IsValidPath(@"C:\\\//\/\\/\\\/abc/\/\/\/\///\\\//\defg");
IsValidPath(@"C:/abc/def~`!@#$%^&()_-+={[}];',.g");
IsValidPath(@"C:\\\\\abc////////defg");
IsValidPath(@"/abc", false);

I noticed this question a couple of days late, but I feel that I can add some insight. I hope this can be helpful towards your RESTful venture.

Point 1: Am I understanding it right?

You understood right. That is a correct representation of a RESTful architecture. You may find the following matrix from Wikipedia very helpful in defining your nouns and verbs:

When dealing with a Collection URI like: http://example.com/resources/

• GET: List the members of the collection, complete with their member URIs for further navigation. For example, list all the cars for sale.

• PUT: Meaning defined as "replace the entire collection with another collection".

• POST: Create a new entry in the collection where the ID is assigned automatically by the collection. The ID created is usually included as part of the data returned by this operation.

• DELETE: Meaning defined as "delete the entire collection".

When dealing with a Member URI like: http://example.com/resources/7HOU57Y

• GET: Retrieve a representation of the addressed member of the collection expressed in an appropriate MIME type.

• PUT: Update the addressed member of the collection or create it with the specified ID.

• POST: Treats the addressed member as a collection in its own right and creates a new subordinate of it.

• DELETE: Delete the addressed member of the collection.

Point 2: I need more verbs

In general, when you think you need more verbs, it may actually mean that your resources need to be re-identified. Remember that in REST you are always acting on a resource, or on a collection of resources. What you choose as the resource is quite important for your API definition.

Activate/Deactivate Login: If you are creating a new session, then you may want to consider "the session" as the resource. To create a new session, use POST to http://example.com/sessions/ with the credentials in the body. To expire it use PUT or a DELETE (maybe depending on whether you intend to keep a session history) to http://example.com/sessions/SESSION_ID.

Change Password: This time the resource is "the user". You would need a PUT to http://example.com/users/USER_ID with the old and new passwords in the body. You are acting on "the user" resource, and a change password is simply an update request. It's quite similar to the UPDATE statement in a relational database.

My instinct would be to do a GET call to a URL like /api/users/1/activate_login

This goes against a very core REST principle: The correct usage of HTTP verbs. Any GET request should never leave any side effect.

For example, a GET request should never create a session on the database, return a cookie with a new Session ID, or leave any residue on the server. The GET verb is like the SELECT statement in a database engine. Remember that the response to any request with the GET verb should be cache-able when requested with the same parameters, just like when you request a static web page.

Point 3: How to return error messages and codes

Consider the 4xx or 5xx HTTP status codes as error categories. You can elaborate the error in the body.

Failed to Connect to Database: / Incorrect Database Login: In general you should use a 500 error for these types of errors. This is a server-side error. The client did nothing wrong. 500 errors are normally considered "retryable". i.e. the client can retry the same exact request, and expect it to succeed once the server's troubles are resolved. Specify the details in the body, so that the client will be able to provide some context to us humans.

The other category of errors would be the 4xx family, which in general indicate that the client did something wrong. In particular, this category of errors normally indicate to the client that there is no need to retry the request as it is, because it will continue to fail permanently. i.e. the client needs to change something before retrying this request. For example, "Resource not found" (HTTP 404) or "Malformed Request" (HTTP 400) errors would fall in this category.

Point 4: How to do authentication

As pointed out in point 1, instead of authenticating a user, you may want to think about creating a session. You will be returned a new "Session ID", along with the appropriate HTTP status code (200: Access Granted or 403: Access Denied).

You will then be asking your RESTful server: "Can you GET me the resource for this Session ID?".

There is no authenticated mode - REST is stateless: You create a session, you ask the server to give you resources using this Session ID as a parameter, and on logout you drop or expire the session.

I would argue against using SqlDataReader here; ADO.NET has lots of edge cases and complications, and in my experience most manually written ADO.NET code is broken in at least one way (usually subtle and contextual).

Tools exist to avoid this. For example, in the case here you want to read a column of strings. Dapper makes that completely painless:

var region = ... // some filter
var vals = connection.Query<string>(
    "select Name from Table where Region=@region", // query
    new { region } // parameters
).AsList();

Dapper here is dealing with all the parameterization, execution, and row processing - and a lot of other grungy details of ADO.NET. The <string> can be replaced with <SomeType> to materialize entire rows into objects.

One thing you can do is get rid of all those onclick attributes and do it the right way with bootstrap. You don't need to open them manually; you can specify the trigger and even subscribe to events before the modal opens so that you can do your operations and populate data in it.

I am just going to show as a static example which you can accommodate in your real world.

On each of your <tr>'s add a data attribute for id (i.e. data-id) with the corresponding id value and specify a data-target, which is a selector you specify, so that when clicked, bootstrap will select that element as modal dialog and show it. And then you need to add another attribute data-toggle=modal to make this a trigger for modal.

  <tr data-toggle="modal" data-id="1" data-target="#orderModal">
            <td>1</td>
            <td>24234234</td>
            <td>A</td>
  </tr>
  <tr data-toggle="modal" data-id="2" data-target="#orderModal">
            <td>2</td>
            <td>24234234</td>
            <td>A</td>
        </tr>
  <tr data-toggle="modal" data-id="3" data-target="#orderModal">
            <td>3</td>
            <td>24234234</td>
            <td>A</td>
  </tr>

And now in the javascript just set up the modal just once and event listen to its events so you can do your work.

$(function(){
    $('#orderModal').modal({
        keyboard: true,
        backdrop: "static",
        show:false,

    }).on('show', function(){ //subscribe to show method
          var getIdFromRow = $(event.target).closest('tr').data('id'); //get the id from tr
        //make your ajax call populate items or what even you need
        $(this).find('#orderDetails').html($('<b> Order Id selected: ' + getIdFromRow  + '</b>'))
    });
});

Demo

Do not use inline click attributes any more. Use event bindings instead with vanilla js or using jquery.

Alternative ways here:

Demo2 or Demo3

Just run the following line in your favorite terminal application:

echo export PATH="/usr/local/bin:$PATH" >> ~/.bash_profile

Restart your terminal and run

brew doctor

the issue should be resolved

One more point I haven't found anyone mentioned:

If you have virtual method, each declaration can have its own default value!

It depends on the interface you are calling which value will be used.

Example on ideone

struct iface
{
    virtual void test(int a = 0) { std::cout << a; }
};

struct impl : public iface
{
    virtual void test(int a = 5) override { std::cout << a; }
};

int main()
{
    impl d;
    d.test();
    iface* a = &d;
    a->test();
}

It prints 50

I strongly discourage you to use it like this

<LinearLayout
    android:id="@+id/linear1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:weightSum="9"
    android:orientation="horizontal" >

    <ImageView
        android:id="@+id/ring_oss"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="3"
        android:src="@drawable/ring_oss" />

    <ImageView
        android:id="@+id/maila_oss"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="3"
        android:src="@drawable/maila_oss" />
<EditText
        android:id="@+id/edittxt"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="3"
        android:src="@drawable/maila_oss" />
</LinearLayout>

You can stop the 2-line separation in the output by using

    with open('t.ini') as f:
       for line in f:
           print line.strip()
           if 'str' in line:
              break

A small virtual machine maybe?

Try VirtualBox a freeware program to install virtual machines (a lot of work for what you want to do, but it'll work)

I did want to obmit a old big history and start from a fresh commit i choosed to:

rsync -a --exclude '.git' old-repo/ new-repo/
cd new-repo 
git push 

when now old-repo changes i can apply the patches to the new-repo to rebase them on the new-repo.

Now that the Web Audio API is here and gaining browser support, that could be a more robust option.

Zounds is a primitive wrapper around that API for playing simple one-shot sounds with a minimum of boilerplate at the point of use.

I know this is an old Question

But in case you want to do it programmatically or the java way

For Image Backgrounds; you can use BackgroundImage class

BackgroundImage myBI= new BackgroundImage(new Image("my url",32,32,false,true),
        BackgroundRepeat.REPEAT, BackgroundRepeat.NO_REPEAT, BackgroundPosition.DEFAULT,
          BackgroundSize.DEFAULT);
//then you set to your node
myContainer.setBackground(new Background(myBI));

For Paint or Fill Backgrounds; you can use BackgroundFill class

BackgroundFill myBF = new BackgroundFill(Color.BLUEVIOLET, new CornerRadii(1),
         new Insets(0.0,0.0,0.0,0.0));// or null for the padding
//then you set to your node or container or layout
myContainer.setBackground(new Background(myBF));

Keeps your java alive && your css dead..

Setting app:titleTextColor on my android.support.v7.widget.Toolbar works for me on Android 4.4 and on 6.0 too with com.android.support:appcompat-v7:23.1.0:

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_height="wrap_content"
    android:layout_width="match_parent"
    android:minHeight="?attr/actionBarSize"
    android:background="?attr/colorPrimary"
    app:titleTextColor="@android:color/white" />

You can do it without programming. Just open the web site, right-click and select "view source" to open the HTML code of that site. Then in the text editor search for "favicon" - it will direct you to something looking like

<link rel="icon" href='/SOMERELATIVEPATH/favicon.ico' type="image/x-icon" />

take the string in href and append it to the web site's base URL (let's assume it is "http://WEBSITE/"), so it looks like

http://WEBSITE/SOMERELATIVEPATH/favicon.ico

which is the absolute path to the favicon. If you didn't find it this way, it can be as well in the root in which case the URL is http://WEBSITE/favicon.ico.

Take the URL you determined and insert it into the following code:

<html>
  <head>
   <title>Capture Favicon</title>   
  </head>
  <body>
    <a href='http://WEBSITE/SOMERELATIVEPATH/favicon.ico' alt="Favicon"/>Favicon</a> 
  </body>
</html>

Save this HTML code locally (e.g. on your desktop) as GetFavicon.html and then double-click on it to open it. It will display only a link named Favicon. Right-click on this link and select "Save target as..." to save the Favicon on your local PC - and you're done!

A fast way to convert strings to an integer is to use a bitwise or, like so:

x | 0

While it depends on how it is implemented, in theory it should be relatively fast (at least as fast as +x) since it will first cast x to a number and then perform a very efficient or.

In my case, it was the attachment size limit that causes the issue. Check and increase the size limit of mail worked for me.

Try this code, you can set loading image with it, so the users knows that your app is loading an image from url:

UIImageView *yourImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"loading.png"]];
    [yourImageView setContentMode:UIViewContentModeScaleAspectFit];

    //Request image data from the URL:
    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
        NSData *imgData = [NSData dataWithContentsOfURL:[NSURL URLWithString:@"http://yourdomain.com/yourimg.png"]];

        dispatch_async(dispatch_get_main_queue(), ^{
            if (imgData)
            {
                //Load the data into an UIImage:
                UIImage *image = [UIImage imageWithData:imgData];

                //Check if your image loaded successfully:
                if (image)
                {
                    yourImageView.image = image;
                }
                else
                {
                    //Failed to load the data into an UIImage:
                    yourImageView.image = [UIImage imageNamed:@"no-data-image.png"];
                }
            }
            else
            {
                //Failed to get the image data:
                yourImageView.image = [UIImage imageNamed:@"no-data-image.png"];
            }
        });
    });

Only the OR part is tricky, but with a general boolean expression containing NOT OR AND the only nice solution is this:

REM if A == B OR C == C then yes

(call :strequ A B || call :strequ C C) && echo yes
exit /b

:strequ
if "%1" == "%2" exit /b 0
exit /b 1

I have written a batch file CompileCS.cmd which allows to compile (and optionally run) a C# file, you can find the complete answer including the batch program 'CompileCS' here.

Its usage is simple:

CompileCS /run GetDotNetVersion.cs[arg1] ... [arg9]

will compile and run GetDotNetVersion.cs - if you just want to compile it, omit the /run parameter.

The console application GetDotNetVersion.cs is taken from this answer.

In C#, you can create delegates as function pointers. Check out the following MSDN article for information on usage: http://msdn.microsoft.com/en-us/library/ms173171(VS.80).aspx

    public static void hello()
    {
        Console.Write("hello world");
    }

   /* code snipped */

    public delegate void functionPointer();

    functionPointer foo = hello;
    foo();  // Writes hello world to the console.

Solution:

sort -k 2 -n filename

more verbosely written as:

sort --key 2 --numeric-sort filename

Example:

$ cat filename
A 12
B 48
C 3

$ sort --key 2 --numeric-sort filename 
C 3
A 12
B 48

Explanation:

• -k # - this argument specifies the first column that will be used to sort. (note that column here is defined as a whitespace delimited field; the argument -k5 will sort starting with the fifth field in each line, not the fifth character in each line)

• -n - this option specifies a "numeric sort" meaning that column should be interpreted as a row of numbers, instead of text.

More:

Other common options include:

• -r - this option reverses the sorting order. It can also be written as --reverse.
• -i - This option ignores non-printable characters. It can also be written as --ignore-nonprinting.
• -b - This option ignores leading blank spaces, which is handy as white spaces are used to determine the number of rows. It can also be written as --ignore-leading-blanks.
• -f - This option ignores letter case. "A"=="a". It can also be written as --ignore-case.
• -t [new separator] - This option makes the preprocessing use a operator other than space. It can also be written as --field-separator.

There are other options, but these are the most common and helpful ones, that I use often.

SET A uses short-circuiting boolean operators.

What 'short-circuiting' means in the context of boolean operators is that for a set of booleans b1, b2, ..., bn, the short circuit versions will cease evaluation as soon as the first of these booleans is true (||) or false (&&).

For example:

// 2 == 2 will never get evaluated because it is already clear from evaluating
// 1 != 1 that the result will be false.
(1 != 1) && (2 == 2)

// 2 != 2 will never get evaluated because it is already clear from evaluating
// 1 == 1 that the result will be true.
(1 == 1) || (2 != 2)

Maybe you should have a look at Mapquests Traffic API: http://www.mapquestapi.com/traffic/

The webservice is unfortunately only available for some citys in the US, I think. But probably it solves your problem.

My understanding is if you set controls.Visible = false during initial page load, it doesn't get rendered in the client response. My suggestion to solve your problem is

Don't use placeholder, judging from the scenario, you don't really need a placeholder, unless you need to dynamically add controls on the server side. Use div, without runat=server. You can always controls the visiblity of that div using css. If you need to add controls dynamically later, use placeholder, but don't set visible = false. Placeholder won't have any display anyway, Set the visibility of that placeholder using css. Here's how to do it programmactically :

placeholderId.Attributes["style"] = "display:none";

Anyway, as other have stated, your problems occurs because once you set control.visible = false, it doesn't get rendered in the client response.

The latest plugin is tidy2, which can be installed through Plugins>Plugin Manager>Show Plugin Manager.

I suggest editing config 1 and setting quote-marks: no, especially if you have script that makes use of quotes.

Also, tidying more than once can result in inserting ampersands the first time and then replacing the ampersands the second time. You may want to play with the config to get it to where you need it.

I would combine node-http-proxy and express.

node-http-proxy will support a proxy inside your node.js web server via RoutingProxy (see the example called Proxy requests within another http server).

Inside your custom server logic you can do authentication using express. See the auth sample here for an example.

Combining those two examples should give you what you want.

Try this 100% Working Code

string SQL = "", tableName = "tableName";
for (int i = 0; i < dataGridView1.Rows.Count; i++)
{
    SQL = @"INSERT INTO " + tableName + " VALUES (";
    for (int col = 0; col < dataGridView1.ColumnCount; col++)
    {
        string data = "";
        if (dataGridView1.Rows[i].Cells[col].Value != null)
        {
            data = dataGridView1.Rows[i].Cells[col].Value.ToString();
        }
        SQL += "'" + data.Trim() + "'";
        if (col < dataGridView1.ColumnCount - 1)
        {
            SQL += ",";
        }
    }
    SQL += ")";
    string finalSQL = SQL;
    //INSERT to DB the finalSQL
}

Your Data is ready now Insert the finalSQL in your database with your connection

What's wrong with just simply using a single, simple UPDATE statement??

UPDATE dbo.Coupon
SET NoofUses = (SELECT COUNT(*) FROM dbo.CouponUse WHERE Couponid = dbo.Coupon.ID)

That's all that's needed ! No messy and complicated cursor, no looping, no RBAR (row-by-agonizing-row) processing ..... just a nice, simple, clean set-based SQL statement.

This should do the trick:

image = open("image.png", "wb")
image.write(base64string.decode('base64'))
image.close()

Coffee Cup Just released one. July 6, 2010 http://www.coffeecup.com/html-editor/

They now also have an OS X version in beta — see also this stackoverflow post.

Sometimes you don't want to create a html e-mail. I solved the problem this way :

Replace \n by \t\n

The tab will not be shown, but the newline will work.

in java 7

public class Main {
    public static void main(String[] args) {
        byte b =  -2;
        int i = 0 ;
        i = ( b & 0b1111_1111 ) ;
        System.err.println(i);
    }
}

result : 254

Since the behavior is kind of strange, I have done some testing on the behavior, and here's my result:

TL;DR

If you are:

• In a form, and
• uses onclick="xxx()" on an element
• don't add id="xxx" or name="xxx" to that element
  • (e.g. <form><button id="totalbandwidth" onclick="totalbandwidth()">BAD</button></form> )

Here's are some test and their result:

Control sample (can successfully call function)

function totalbandwidth(){ alert("Total Bandwidth > 9000Mbps"); }

<form onsubmit="return false;">
  <button onclick="totalbandwidth()">SUCCESS</button>
</form>

Add id to button (failed to call function)

function totalbandwidth(){ alert("Total Bandwidth > 9000Mbps"); }

<form onsubmit="return false;">
  <button id="totalbandwidth" onclick="totalbandwidth()">FAILED</button>
</form>

Add name to button (failed to call function)

function totalbandwidth(){ alert("Total Bandwidth > 9000Mbps"); }

<form onsubmit="return false;">
  <button name="totalbandwidth" onclick="totalbandwidth()">FAILED</button>
</form>

Add value to button (can successfully call function)

function totalbandwidth(){ alert("Total Bandwidth > 9000Mbps"); }

<form onsubmit="return false;">
  <input type="button" value="totalbandwidth" onclick="totalbandwidth()" />SUCCESS
</form>

Add id to button, but not in a form (can successfully call function)

function totalbandwidth(){ alert("Total Bandwidth > 9000Mbps"); }

<button id="totalbandwidth" onclick="totalbandwidth()">SUCCESS</button>

Add id to another element inside the form (can successfully call function)

function totalbandwidth(){ alert("The answer is no, the span will not affect button"); }

<form onsubmit="return false;">
<span name="totalbandwidth" >Will this span affect button? </span>
<button onclick="totalbandwidth()">SUCCESS</button>
</form>

[[ There are some good answers here but I find that they still are lacking a bit of information. ]]

return (new StringBuilder("select id1, " + " id2 " + " from " + " table"))
     .toString();

So as you point out, the example you give is a simplistic but let's analyze it anyway. What happens here is the compiler actually does the + work here because "select id1, " + " id2 " + " from " + " table" are all constants. So this turns into:

return new StringBuilder("select id1,  id2  from  table").toString();

In this case, obviously, there is no point in using StringBuilder. You might as well do:

// the compiler combines these constant strings
return "select id1, " + " id2 " + " from " + " table";

However, even if you were appending any fields or other non-constants then the compiler would use an internal StringBuilder -- there's no need for you to define one:

// an internal StringBuilder is used here
return "select id1, " + fieldName + " from " + tableName;

Under the covers, this turns into code that is approximately equivalent to:

StringBuilder sb = new StringBuilder("select id1, ");
sb.append(fieldName).append(" from ").append(tableName);
return sb.toString();

Really the only time you need to use StringBuilder directly is when you have conditional code. For example, code that looks like the following is desperate for a StringBuilder:

// 1 StringBuilder used in this line
String query = "select id1, " + fieldName + " from " + tableName;
if (where != null) {
   // another StringBuilder used here
   query += ' ' + where;
}

The + in the first line uses one StringBuilder instance. Then the += uses another StringBuilder instance. It is more efficient to do:

// choose a good starting size to lower chances of reallocation
StringBuilder sb = new StringBuilder(64);
sb.append("select id1, ").append(fieldName).append(" from ").append(tableName);
// conditional code
if (where != null) {
   sb.append(' ').append(where);
}
return sb.toString();

Another time that I use a StringBuilder is when I'm building a string from a number of method calls. Then I can create methods that take a StringBuilder argument:

private void addWhere(StringBuilder sb) {
   if (where != null) {
      sb.append(' ').append(where);
   }
}

When you are using a StringBuilder, you should watch for any usage of + at the same time:

sb.append("select " + fieldName);

That + will cause another internal StringBuilder to be created. This should of course be:

sb.append("select ").append(fieldName);

Lastly, as @T.J.rowder points out, you should always make a guess at the size of the StringBuilder. This will save on the number of char[] objects created when growing the size of the internal buffer.

The problem is that if you include fun.cpp in two places in your program, you will end up defining it twice, which isn't valid.

You don't want to include cpp files. You want to include header files.

The header file should just have the class definition. The corresponding cpp file, which you will compile separately, will have the function definition.

fun.hpp:

#include <iostream>

class classA {
    friend void funct();
public:
    classA(int a=1,int b=2):propa(a),propb(b){std::cout<<"constructor\n";}
private:
    int propa;
    int propb;
    void outfun(){
        std::cout<<"propa="<<propa<<endl<<"propb="<<propb<< std::endl;
    }
};

fun.cpp:

#include "fun.hpp"

using namespace std;

void funct(){
    cout<<"enter funct"<<endl;
    classA tmp(1,2);
    tmp.outfun();
    cout<<"exit funct"<<endl;
}

mainfile.cpp:

#include <iostream>
#include "fun.hpp"
using namespace std;

int main(int nargin,char* varargin[]) {
    cout<<"call funct"<<endl;
    funct();
    cout<<"exit main"<<endl;
    return 0;
}

Note that it is generally recommended to avoid using namespace std in header files.

You can also use parameter expansion:

$ filename=foo.txt
$ echo "${filename%.*}"
foo

Just be aware that if there is no file extension, it will look further back for dots, e.g.

• If the filename only starts with a dot (e.g. .bashrc) it will remove the whole filename.
• If there's a dot only in the path (e.g. path.to/myfile or ./myfile), then it will trim inside the path.
