This also works to turn []byte into io.Reader

See my code:

            {
                let alert = UIAlertView(title: "Oops! Empty Field", message: "Please enter the amount", delegate: nil, cancelButtonTitle: "OK")

                alert.show()
            }

            else {

            var alertController = UIAlertController(title: "Confirm Bid Amount", message: "Final Bid Amount : "+amountTF.text , preferredStyle: .Alert)
            var okAction = UIAlertAction(title: "Confirm", style: UIAlertActionStyle.Default) {
                UIAlertAction in

                JHProgressHUD.sharedHUD.loaderColor = UIColor.redColor()
                        JHProgressHUD.sharedHUD.showInView(self.view, withHeader: "Amount registering" , andFooter: "Loading")
                }
            var cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel) {

MIME stands for Multipurpose Internet Mail Extensions. It's a way of identifying files on the Internet according to their nature and format.

For example, using the Content-type header value defined in a HTTP response, the browser can open the file with the proper extension/plugin.

Internet Media Type (also Content-type) is the same as a MIME type. MIME types were originally created for emails sent using the SMTP protocol. Nowadays, this standard is used in a lot of other protocols, hence the new naming convention "Internet Media Type".

A MIME type is a string identifier composed of two parts: a type and a subtype.

• The "type" refers to a logical grouping of many MIME types that are closely related to each other; it's no more than a high level category.
• "subtypes" are specific to one file type within the "type".

The x- prefix of a MIME subtype simply means that it's non-standard.
The vnd prefix means that the MIME value is vendor specific.

This link will help you in understanding pass by reference in C#. Basically,when an object of reference type is passed by value to an method, only methods which are available on that object can modify the contents of object.

For example List.sort() method changes List contents but if you assign some other object to same variable, that assignment is local to that method. That is why myList remains unchanged.

If we pass object of reference type by using ref keyword then we can assign some other object to same variable and that changes entire object itself.

(Edit: this is the updated version of the documentation linked above.)

You can. Try something like this:

@Path("/todo/{varX}/{varY}")
@Produces({"application/xml", "application/json"})
public Todo whatEverNameYouLike(@PathParam("varX") String varX,
    @PathParam("varY") String varY) {
        Todo todo = new Todo();
        todo.setSummary(varX);
        todo.setDescription(varY);
        return todo;
}

Then call your service with this URL;

CMake is more like a script language if comparing it with other ways to create Makefile (e.g. make or qmake). It is not very cool like Python, but still.

There are no such thing like a "proper way" if looking in various opensource projects how people include directories. But there are two ways to do it.

1. Crude include_directories will append a directory to the current project and all other descendant projects which you will append via a series of add_subdirectory commands. Sometimes people say that such approach is legacy.

2. A more elegant way is with target_include_directories. It allows to append a directory for a specific project/target without (maybe) unnecessary inheritance or clashing of various include directories. Also allow to perform even a subtle configuration and append one of the following markers for this command.

PRIVATE - use only for this specified build target

PUBLIC - use it for specified target and for targets which links with this project

INTERFACE -- use it only for targets which links with the current project

PS:

1. Both commands allow to mark a directory as SYSTEM to give a hint that it is not your business that specified directories will contain warnings.

2. A similar answer is with other pairs of commands target_compile_definitions/add_definitions, target_compile_options/CMAKE_C_FLAGS

Here is how you do it with some simple Excel formulae, and no fancy VBA needed. The trick is to use the OFFSET formula. Please see this example spreadsheet:

Is there an equivalent to isscalar() in numpy? Yes.

>>> np.isscalar(3.1)
True
>>> np.isscalar([3.1])
False
>>> np.isscalar(False)
True
>>> np.isscalar('abcd')
True

Editing or overriding the row in Twitter bootstrap is a bad idea, because this is a core part of the page scaffolding and you will need rows without a top margin.

To solve this, instead create a new class "top-buffer" that adds the standard margin that you need.

.top-buffer { margin-top:20px; }

And then use it on the row divs where you need a top margin.

<div class="row top-buffer"> ...

I just found this extension called beautify in the Market Place and yes, it's another config\settings file. :)

Beautify javascript, JSON, CSS, Sass, and HTML in Visual Studio Code.

VS Code uses js-beautify internally, but it lacks the ability to modify the style you wish to use. This extension enables running js-beautify in VS Code, AND honouring any .jsbeautifyrc file in the open file's path tree to load your code styling. Run with F1 Beautify (to beautify a selection) or F1 Beautify file.

For help on the settings in the .jsbeautifyrc see Settings.md

As of Java 9 you can use List.of(...), JavaDoc.

This method returns an immutable List and is very efficient.

You don't have to copy everything to C:\dotnet35. Usually all the files are already copied to the folder C:\Windows\WinSxS. Then the command becomes (assuming Windows was installed to C:): "Dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:C:\Windows\WinSxS /LimitAccess" If not you can also point the command to the DVD directly. Then the command becomes (assuming DVD is mounted to D:): "Dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:D:\sources\sxs /LimitAccess".

Recently I had the same problem when using htmlTable() (‘htmlTable’ package) and I found a simpler solution: convert the data frame to a matrix with as.matrix():

htmlTable(as.matrix(df))

And be sure that the rownames are just indices. as.matrix() conservs the same columnames. That's it.

UPDATE

Following the comment of @DMR, I did't notice that htmlTable() has the parameter rnames = FALSE for cases like this. So a better answer would be:

htmlTable(df, rnames = FALSE)

Try to use the rack-cors gem. And add the header field in your Ajax call.

the other answers help to understand how to maintain such a session. Additionally, I want to provide a class which keeps the session maintained over different runs of a script (with a cache file). This means a proper "login" is only performed when required (timout or no session exists in cache). Also it supports proxy settings over subsequent calls to 'get' or 'post'.

A code snippet for using the above class may look like this:

if __name__ == "__main__":
    # proxies = {'https' : 'https://user:pass@server:port',
    #           'http' : 'http://user:pass@server:port'}

    loginData = {'user' : 'usr',
                 'password' :  'pwd'}

    loginUrl = 'https://...'
    loginTestUrl = 'https://...'
    successStr = 'Hello Tom'
    s = MyLoginSession(loginUrl, loginData, loginTestUrl, successStr, 
                       #proxies = proxies
                       )

    res = s.retrieveContent('https://....')
    print(res.text)

    # if, for instance, login via JSON values required try this:
    s = MyLoginSession(loginUrl, None, loginTestUrl, successStr, 
                       #proxies = proxies,
                       json = loginData)

Finally, I get the cell using the following code:

UITableViewCell *cell = (UITableViewCell *)[(UITableView *)self.view cellForRowAtIndexPath:nowIndex];

Because the class is extended UITableViewController:

@interface SearchHotelViewController : UITableViewController

So, the self is "SearchHotelViewController".

Most of the time, in enterprise applications the Java heap given is larger than the ideal size of max 12 to 16 GB. I have found it hard to make the NetBeans profiler work directly on these big java apps.

But usually this is not needed. You can use the jmap utility that comes with the jdk to take a "live" heap dump , that is jmap will dump the heap after running GC. Do some operation on the application, wait till the operation is completed, then take another "live" heap dump. Use tools like Eclipse MAT to load the heapdumps, sort on the histogram, see which objects have increased, or which are the highest, This would give a clue.

su  proceeuser
/bin/jmap -dump:live,format=b,file=/tmp/2930javaheap.hrpof 2930(pid of process)

There is only one problem with this approach; Huge heap dumps, even with the live option, may be too big to transfer out to development lap, and may need a machine with enough memory/RAM to open.

That is where the class histogram comes into picture. You can dump a live class histogram with the jmap tool. This will give only the class histogram of memory usage.Basically it won't have the information to chain the reference. For example it may put char array at the top. And String class somewhere below. You have to draw the connection yourself.

jdk/jdk1.6.0_38/bin/jmap -histo:live 60030 > /tmp/60030istolive1330.txt

Instead of taking two heap dumps, take two class histograms, like as described above; Then compare the class histograms and see the classes that are increasing. See if you can relate the Java classes to your application classes. This will give a pretty good hint. Here is a pythons script that can help you compare two jmap histogram dumps. histogramparser.py

Finally tools like JConolse and VisualVm are essential to see the memory growth over time, and see if there is a memory leak. Finally sometimes your problem may not be a memory leak , but high memory usage.For this enable GC logging;use a more advanced and new compacting GC like G1GC; and you can use jdk tools like jstat to see the GC behaviour live

jstat -gccause pid <optional time interval>

Other referecences to google for -jhat, jmap, Full GC, Humongous allocation, G1GC

RGB values fall nicely on bit boundaries; decimal digits don't. I don't think there's an easy way to do this using bitwise operators at all. You'd need to use decimal operators like modulo 10 (% 10).

The Above error occurs if any wrong import done. For example sometimes Service files may be added in TestBed.configureTestingModule. And also while importing Material component for example import from

import {MatDialogModule} from '@angular/material/dialog'

not from

import {MatDialogModule} from '@angular/material'

Ok, I have searched several hours now to find the problem, and I found it.

None of the changes like fillViewport="true" or android:windowSoftInputMode="adjustResize" helped me.

I use Android 4.4 and this is the big mistake:

android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen"

Somehow, the Fullscreen themes prevent the ScrollViews from scrolling when the SoftKeyboard is visible.

At the moment, I ended up using this instead:

android:theme="@android:style/Theme.Black.NoTitleBar

I don't know how to get rid of the top system bar with time and battery display, but at least I got the problem.

Hope this helps others who have the same problem.

EDIT: I got a little workaround for my case, so I posted it here:

I am not sure if this will work for you, but it will definitely help you in understanding, and clear some things up.

EDIT2: Here is another good topic that will help you to go in the right direction or even solve your problem.

There have been a slew of recent changes in this arena, so I thought a fresh answer would be helpful.

To have a cookie sent by the browser to another site during a request the following criteria must be met:

• The Set-Cookie header from the target site must contain the SameSite=None and Secure labels. If Secure is not used the SameSite header will be ignored.
• The request must be made to a https endpoint, a requirement of the Secure flag.
• The XHRRequest must be made with withCredentials=true. If using $.ajax() this is accomplished with the xhrFields parameter (requiring jQuery=1.5.1+)
• The server must respond with Access-Control-Allow-Origin header that matches the request Origin header. (* will not be respected in this case)

A lot of people find their way to this post trying to do local development against a remote endpoint, which is possible if the above criteria are met.

var e = $('<div style="display:block; id="myid" float:left;width:'+width+'px; height:'+height+'px; margin-top:'+positionY+'px;margin-left:'+positionX+'px;border:1px dashed #CCCCCC;"></div>');
$("#box").html(e);

Edit: Updated css to match with what you have..

You're connecting to the complete event, not the success event - there's a significant difference and that's why your debugging results aren't as expected. Also, I've never made the signature methods match yours, and I've always provided a contentType and dataType. For example:

$.ajax({
        type: "POST",
        url: "Default.aspx/OnSubmit",
        data: dataValue,                
        contentType: 'application/json; charset=utf-8',
        dataType: 'json',
        error: function (XMLHttpRequest, textStatus, errorThrown) {
            alert("Request: " + XMLHttpRequest.toString() + "\n\nStatus: " + textStatus + "\n\nError: " + errorThrown);
        },
        success: function (result) {
            alert("We returned: " + result);
        }
    });

The one you include last will be the one that is used. Note however that if any rules has !important in the first stylesheet they will take priority.

The simplest way is to create a computed column in XLS that would generate the syntax of the insert statement. Then copy these insert into a text file and then execute on the SQL. The other alternatives are to buy database connectivity add-on's for Excel and write VBA code to accomplish the same.

File -> Invalidate Caches/Restart or rebuilding the project did not work wor me.

What worked for my Gradle project was to "Refresh all Gradle projects" from the Gradle tab on top-right corner of IntelliJ v2017, using the yellow marked button shown below:

 <td rowspan="2" style="text-align:left;vertical-align:top;padding:0">Save a lot</td>

That should do it.

With json-loader installed, now you can simply use:

import suburbs from '../suburbs.json';

or, even more simply:

import suburbs from '../suburbs';

I don't know if that answers your question, but yes, you can use angularjs links, such as:

<a ng-href="http://www.gravatar.com/avatar/{{hash}}"/>

There is a good example on the AngularJS website:

http://docs.angularjs.org/api/ng.directive:ngHref

UPDATE: The AngularJS documentation was a bit obscure and it didn't provide a good solution for it. Sorry!

You can find a better solution here: How to handle anchor hash linking in AngularJS

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

When you set maven scope as provided, it means that when the plugin runs, the actual dependencies version used will depend on the version of Apache Maven you have installed.

you can use the download attribute on an a tag ...

<a href="data:image/jpeg;base64,/9j/4AAQSkZ..." download="filename.jpg"></a>

Make another div and add both 'dummy' and 'img-container' inside the div

Do HTML and CSS like follows

html , body {height:100%;}_x000D_
.responsive-container { height:100%; display:table; text-align:center; width:100%;}_x000D_
.inner-container {display:table-cell; vertical-align:middle;}

<div class="responsive-container">_x000D_
    <div class="inner-container">_x000D_
  <div class="dummy">Sample</div>_x000D_
  <div class="img-container">_x000D_
   Image tag_x000D_
  </div>_x000D_
 </div> _x000D_
</div>

Instead of 100% for the 'responsive-container' you can give the height that you want.,

I had a similar issue with Spring Data MongoDB: I had to add the package path to @EnableMongoRepositories

You can also put in a new virtual Host entry in the

c:\xampp\apache\conf\httpd-vhosts.conf

like:

<VirtualHost *:80>
  ServerAdmin [email protected]
  DocumentRoot "C:/xampp/htdocs/myproject/web"
  ServerName localhost
  ErrorLog "logs/dummy-host2.example.com-error.log"
  CustomLog "logs/dummy-host2.example.com-access.log" common
</VirtualHost>

To get the value from the servlet from POST command, you can follow the approach as explained on this post by using request.getParameter(key) format which will return the value you want.

When is the init() function run?

With Go 1.16 (Q1 2021), you will see precisely when it runs, and for how long.

See commit 7c58ef7 from CL (Change List) 254659, fixing issue 41378 .

Runtime: implement GODEBUG=inittrace=1 support

Setting inittrace=1 causes the runtime to emit a single line to standard error for each package with init work, summarizing the execution time and memory allocation.

The emitted debug information for init functions can be used to find bottlenecks or regressions in Go startup performance.

Packages with no init function work (user defined or compiler generated) are omitted.

Tracing plugin inits is not supported as they can execute concurrently. This would make the implementation of tracing more complex while adding support for a very rare use case. Plugin inits can be traced separately by testing a main package importing the plugins package imports explicitly.

$ GODEBUG=inittrace=1 go test
init internal/bytealg @0.008 ms, 0 ms clock, 0 bytes, 0 allocs
init runtime @0.059 ms, 0.026 ms clock, 0 bytes, 0 allocs
init math @0.19 ms, 0.001 ms clock, 0 bytes, 0 allocs
init errors @0.22 ms, 0.004 ms clock, 0 bytes, 0 allocs
init strconv @0.24 ms, 0.002 ms clock, 32 bytes, 2 allocs
init sync @0.28 ms, 0.003 ms clock, 16 bytes, 1 allocs
init unicode @0.44 ms, 0.11 ms clock, 23328 bytes, 24 allocs
...

Inspired by [email protected] who instrumented doInit in a prototype to measure init times with GDB.

I can confirm that my original code seems to work. I was casually sticking to an image with a wrong path.

Facebook is using LAMP structure. Facebook’s back-end services are written in a variety of different programming languages including C++, Java, Python, and Erlang and they are used according to requirement. With LAMP Facebook uses some technologies ,to support large number of requests, like

1. Memcache - It is a memory caching system that is used to speed up dynamic database-driven websites (like Facebook) by caching data and objects in RAM to reduce reading time. Memcache is Facebook’s primary form of caching and helps alleviate the database load. Having a caching system allows Facebook to be as fast as it is at recalling your data.

2. Thrift (protocol) - It is a lightweight remote procedure call framework for scalable cross-language services development. Thrift supports C++, PHP, Python, Perl, Java, Ruby, Erlang, and others.

3. Cassandra (database) - It is a database management system designed to handle large amounts of data spread out across many servers.

4. HipHop for PHP - It is a source code transformer for PHP script code and was created to save server resources. HipHop transforms PHP source code into optimized C++. After doing this, it uses g++ to compile it to machine code.

If we go into more detail, then answer to this question go longer. We can understand more from following posts:

1. How Does Facebook Work?
2. Data Management, Facebook-style
3. Facebook database design?
4. Facebook wall's database structure
5. Facebook "like" data structure

First, add the Material Design dependency.

implementation 'com.google.android.material:material:<version>'

To get the latest material design library version. check the official website github repository.

Current version is 1.2.0.

So, you have to add,

implementation 'com.google.android.material:material:1.2.0'

Then, you need to change the app theme to material theme by adding,

<style name="AppTheme" parent="Theme.MaterialComponents.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

in your style.xml. Dont forget to set the same theme in your application theme in your manifest file.

Based on Tomasz Nurkiewiczs answer, the "problem" is that typescript is typesafe. :) So the document.getElementById() returns the type HTMLElement which does not contain a value property. The subtype HTMLInputElement does however contain the value property.

So a solution is to cast the result of getElementById() to HTMLInputElement like this:

var inputValue = (<HTMLInputElement>document.getElementById(elementId)).value;

<> is the casting operator in typescript. See the question TypeScript: casting HTMLElement.

The resulting javascript from the line above looks like this:

inputValue = (document.getElementById(elementId)).value;

i.e. containing no type information.

I am assuming that you have enough permissions to create this directory.

To fix your problem, you can either ssh to some other location:

ssh [email protected]

and accept new key - it will create directory ~/.ssh and known_hosts underneath, or simply create it manually using

mkdir ~/.ssh
chmod 700 ~/.ssh

Note that chmod 700 is an important step!

After that, ssh-keygen should work without complaints.

Yes, on Arrays.asList, returning a fixed-size list.

Other than using a linked list, simply use addAll method list.

Example:

String idList = "123,222,333,444";

List<String> parentRecepeIdList = new ArrayList<String>();

parentRecepeIdList.addAll(Arrays.asList(idList.split(","))); 

parentRecepeIdList.add("555");

Another library that supports this is jOO?, and its Seq.distinct(Function<T,U>) method:

Seq.seq(persons).distinct(Person::getName).toList();

Under the hood, it does practically the same thing as the accepted answer, though.

checkout this article :http://www.morgantechspace.com/2013/08/convert-object-to-byte-array-and-vice.html

Use the below code

// Convert an object to a byte array
private byte[] ObjectToByteArray(Object obj)
{
    if(obj == null)
        return null;

    BinaryFormatter bf = new BinaryFormatter();
    MemoryStream ms = new MemoryStream();
    bf.Serialize(ms, obj);

    return ms.ToArray();
}

// Convert a byte array to an Object
private Object ByteArrayToObject(byte[] arrBytes)
{
    MemoryStream memStream = new MemoryStream();
    BinaryFormatter binForm = new BinaryFormatter();
    memStream.Write(arrBytes, 0, arrBytes.Length);
    memStream.Seek(0, SeekOrigin.Begin);
    Object obj = (Object) binForm.Deserialize(memStream);

    return obj;
}

Here is a very simple answer to your question. It works.

import java.time.*;
import java.util.*;
import java.time.format.DateTimeFormatter;
import java.time.temporal.ChronoUnit;

public class MyClass {
public static void main(String args[]) {
    DateTimeFormatter T = DateTimeFormatter.ofPattern("dd/MM/yyyy HH:mm");
    Scanner h = new Scanner(System.in);

    System.out.print("Enter date of birth[dd/mm/yyyy hh:mm]: ");
    String b = h.nextLine();

    LocalDateTime bd = LocalDateTime.parse(b,T);
    LocalDateTime cd = LocalDateTime.now();

    long minutes = ChronoUnit.MINUTES.between(bd, cd);
    long hours = ChronoUnit.HOURS.between(bd, cd);

    System.out.print("Age is: "+hours+ " hours, or " +minutes+ " minutes old");
}
}

object-fit, behaves like background-size, solving the issue of scaling images up and down to fit.

The object-fit CSS property specifies how the contents of a replaced element should be fitted to the box established by its used height and width.

https://developer.mozilla.org/en-US/docs/Web/CSS/object-fit

.cover img {
    width: 100%;
    height: 100%;
    object-fit: cover;
    overflow: hidden;
}

Browser Support

There's no IE support, and support in Edge begins at v16, only for img element: https://caniuse.com/#search=object-fit

The bfred-it/object-fit-images polyfill works very well for me in IE11, tested on Browserstack: demo.

Alternative without polyfill using an image in SVG

For Edge pre v16, and ie9, ie10, ie11:

You can crop and scale any image using CSS object-fit and object-position. However, these properties are only supported in the latest version of MS Edge as well as all other modern browsers.

If you need to crop and scale an image in Internet Explorer and provide support back to IE9, you can do that by wrapping the image in an <svg>, and using the viewBox and preserveAspectRatio attributes to do what object-fit and object-position do.

http://www.sarasoueidan.com/blog/svg-object-fit/#summary-recap

(The author explains the technique thoroughly, and duplicating the detail here would be impractical.)

If you want to redirect your webpage to another HTML FILE, just use as followed:

<meta http-equiv="refresh" content"2;otherpage.html">

2 being the seconds you want the client to wait before redirecting. Use "url=" only when it's an URL, to redirect to an HTML file just write the name after the ';'

In my case a misplaced session.clear() was causing this problem.

that evidently powershell's cmdlets such as copy-item, test-path, etc do not support alternate credentials...

It looks like they do here, copy-item certainly includes a -Credential parameter.

PS C:\> gcm -syn copy-item
Copy-Item [-Path] <String[]> [[-Destination] <String>] [-Container] [-Force] [-Filter <String>] [-I
nclude <String[]>] [-Exclude <String[]>] [-Recurse] [-PassThru] [-Credential <PSCredential>] [...]

You can just use:

> names(LIST)
[1] "A" "B"

Obviously the names of the first element is just

> names(LIST)[1]
[1] "A"

@BrainSlugs83

You shouldn't blindly trust everything posted on stackoverflow. The comment in Jens code is incorrect, the parameter doesn't control whether exceptions are thrown or not.

MSDN is very clear what that parameter controls, have you read it? http://msdn.microsoft.com/en-us/library/dd321703(v=vs.110).aspx

If throwOnFirstException is true, an exception will immediately propagate out of the call to Cancel, preventing the remaining callbacks and cancelable operations from being processed. If throwOnFirstException is false, this overload will aggregate any exceptions thrown into an AggregateException, such that one callback throwing an exception will not prevent other registered callbacks from being executed.

The variable name is also wrong because Cancel is called on CancellationTokenSource not the token itself and the source changes state of each token it manages.

Try this

ALTER DATABASE XXXX  SET RECOVERY SIMPLE

use XXXX

declare @log_File_Name varchar(200) 

select @log_File_Name  = name from sysfiles where filename like '%LDF'

declare @i int = FILE_IDEX ( @log_File_Name)

dbcc shrinkfile ( @i , 50) 

Why not use Model.update? After all you're not using the found user for anything else than to update it's properties:

User.update({username: oldUsername}, {
    username: newUser.username, 
    password: newUser.password, 
    rights: newUser.rights
}, function(err, numberAffected, rawResponse) {
   //handle it
})

You can use:

NOW() + INTERVAL 1 DAY

If you are only interested in the date, not the date and time then you can use CURDATE instead of NOW:

CURDATE() + INTERVAL 1 DAY

Please check you are using // not \\ by-mistake , like below

I found a solution that works for me:

$.fn.setCursorPosition = function(position){
    if(this.length == 0) return this;
    return $(this).setSelection(position, position);
}

$.fn.setSelection = function(selectionStart, selectionEnd) {
    if(this.length == 0) return this;
    var input = this[0];

    if (input.createTextRange) {
        var range = input.createTextRange();
        range.collapse(true);
        range.moveEnd('character', selectionEnd);
        range.moveStart('character', selectionStart);
        range.select();
    } else if (input.setSelectionRange) {
        input.focus();
        input.setSelectionRange(selectionStart, selectionEnd);
    }

    return this;
}

$.fn.focusEnd = function(){
    this.setCursorPosition(this.val().length);
            return this;
}

Now you can move the focus to the end of any element by calling:

$(element).focusEnd();

Or you specify the position.

$(element).setCursorPosition(3); // This will focus on the third character.

The socket has been closed by the client (browser).

A bug in your code:

byte[] outputByte=new byte[4096];
while(in.read(outputByte,0,4096)!=-1){
   output.write(outputByte,0,4096);
}

The last packet read, then write may have a length < 4096, so I suggest:

byte[] outputByte=new byte[4096];
int len;
while(( len = in.read(outputByte, 0, 4096 )) > 0 ) {
   output.write( outputByte, 0, len );
}

It's not your question, but it's my answer... ;-)

When you try to merge one commit with a commit that can be reached by following the first commit’s history, Git simplifies things by moving the pointer forward because there is no divergent work to merge together – this is called a “fast-forward.”

For more : http://git-scm.com/book/en/v2/Git-Branching-Basic-Branching-and-Merging

In another way,

If Master has not diverged, instead of creating a new commit, git will just point master to the latest commit of the feature branch. This is a “fast forward.”

There won't be any "merge commit" in fast-forwarding merge.

If you put sys.path.append('dir/to/path') without check it is already added, you could generate a long list in sys.path. For that, I recommend this:

import sys
import os # if you want this directory

try:
    sys.path.index('/dir/path') # Or os.getcwd() for this directory
except ValueError:
    sys.path.append('/dir/path') # Or os.getcwd() for this directory

SELECT * FROM table ORDER BY id DESC LIMIT 50

save resources make one query, there is no need to make nested queries

To patch the built-in open() function with unittest:

This worked for a patch to read a json config.

class ObjectUnderTest:
    def __init__(self, filename: str):
        with open(filename, 'r') as f:
            dict_content = json.load(f)

The mocked object is the io.TextIOWrapper object returned by the open() function

@patch("<src.where.object.is.used>.open",
        return_value=io.TextIOWrapper(io.BufferedReader(io.BytesIO(b'{"test_key": "test_value"}'))))
    def test_object_function_under_test(self, mocker):

Or Select range and Format cells > Custom \"@\"

I'm not sure if this is available on OS X, but on linux I would make use of the module command. See here.

Set up the modulefile correctly, then add something like this to your rc file (e.g. ~/.bashrc):

module load python3.3

This will make it so that your paths get switched around as required when you log in without impacting any system defaults.

This is not as easy as it seems, some core library functions don't work when only str is overwritten (checked with Python 2.7), see this thread for examples How to make a class JSON serializable Also, try this

import json

class A(unicode):
    def __str__(self):
        return 'a'
    def __unicode__(self):
        return u'a'
    def __repr__(self):
        return 'a'

a = A()
json.dumps(a)

produces

'""'

and not

'"a"'

as would be expected.

EDIT: answering mchicago's comment:

unicode does not have any attributes -- it is an immutable string, the value of which is hidden and not available from high-level Python code. The json module uses re for generating the string representation which seems to have access to this internal attribute. Here's a simple example to justify this:

b = A('b') print b

produces

'a'

while

json.dumps({'b': b})

produces

{"b": "b"}

so you see that the internal representation is used by some native libraries, probably for performance reasons.

See also this for more details: http://www.laurentluce.com/posts/python-string-objects-implementation/

Use isinstance, nothing else:

if isinstance(x, pd.DataFrame):
    ... # do something

PEP8 says explicitly that isinstance is the preferred way to check types

No:  type(x) is pd.DataFrame
No:  type(x) == pd.DataFrame
Yes: isinstance(x, pd.DataFrame)

And don't even think about

if obj.__class__.__name__ = 'DataFrame':
    expect_problems_some_day()

isinstance handles inheritance (see What are the differences between type() and isinstance()?). For example, it will tell you if a variable is a string (either str or unicode), because they derive from basestring)

if isinstance(obj, basestring):
    i_am_string(obj)

Specifically for pandas DataFrame objects:

import pandas as pd
isinstance(var, pd.DataFrame)

Apply following line in your EditText in XML.

android:inputType="textCapSentences|textMultiLine"

It will also allow multi-line support.

Here are 3 different methods to check this

<?php
//Method 1
if(!empty($_GET))
echo "exist";
else
echo "do not exist";
//Method 2
echo "<br>";
if($_GET)
echo "exist";
else
echo "do not exist";
//Method 3
if(count($_GET))
echo "exist";
else
echo "do not exist";
?>

Yes, it's possible with a bit of tweak. Unfortunately, you still have to have VS 2010 installed.

1. First, install XNA Game Studio 4.0. The easiest way is to install the Windows Phone SDK 7.1 which contains everything required.

2. Copy the XNA Game Extension from VS 10 to VS 11 by opening a command prompt 'as administrator' and executing the following (may vary if not x64 computer with defaults paths) :

   xcopy /e "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\Extensions\Microsoft\XNA Game Studio 4.0" "C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\Extensions\Microsoft\XNA Game Studio 4.0"

3. Run notepad as administrator then open extension.vsixmanifest in the destination directory just created.

4. Upgrade the Supported product version to match the new version (or duplicate the whole VisualStudio element and change the Version attribute, as @brainslugs83 said in comments):

   <SupportedProducts>
     <VisualStudio Version="11.0">
       <Edition>VSTS</Edition>
       <Edition>VSTD</Edition>
       <Edition>Pro</Edition>
       <Edition>VCSExpress</Edition>
       <Edition>VPDExpress</Edition>
     </VisualStudio>
   </SupportedProducts>
   

5. Don't forget to clear/delete your cache in %localappdata%\Microsoft\VisualStudio\12.0\Extensions.

6. You may have to run the command to tells Visual Studio that new extensions are available. If you see an 'access denied' message, try launching the console as an administrator.

   "C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\devenv.exe" /setup
   

This has been tested for Windows Games, but not WP7 or Xbox games.

[Edit] According Jowsty, this works also for XBox 360 Games.

[Edit for Visual Studio 2013 & Windows 8.1] See here for documentation on installing Windows Phone SDK 7.1 on Windows 8.1. Use VS version number 12.0 in place of 11.0 for all of these steps, and they will still work correctly.

Yes its possible. Return a RedirectToAction() method like this:

return RedirectToAction("ActionOrViewName", "ControllerName");

The answer by waqas716 is good. I created a workaround for a specific case demanding less code and maintenance.

I found a specific work around by having a static method fetch a view from the activity I suspect to be in the foreground. You can iterate through all activities and check if you wish or get the activity name from martin's answer

ActivityManager am = (ActivityManager)context.getSystemService(Context.ACTIVITY_SERVICE);
ComponentName cn = am.getRunningTasks(1).get(0).topActivity; 

I then check if the view is not null and get the context via getContext().

View v = SuspectedActivity.get_view();

If you have installed SQL 2005 express edition and want to install BIDS (Business Intelligence Development Studio) then go to here Microsoft SQL Server 2005 Express Edition Toolkit

This has an option to install BIDS on my machine, and is the only way l could get hold of BIDS for SQL Server 2005 express edition.

Also this package l think has also allowed me to install both BIDS 2005 & 2008 express edition on the same machine.

In my case, the problem was caused by starting my app from a shortcut on the public desktop (windows 7). As a result, as far as I can tell, the temporary files location was set to c:\users\public\etc. This resulted in the unable to write to cache detail. When I reset to defaults in the temporary files control applet, all worked fine.

The basic difference between Servlets and JSP is that in Servlets we write java code and in that we embed HTML code and there is just reverse case with JSP . In JSP we write HTML code and in that we embed java code using tags provided by JSP.

Use seaborn instead i am using distplot of seaborn with mean=5 std=3 of 1000 values

value = np.random.normal(loc=5,scale=3,size=1000)
sns.distplot(value)

You will get a normal distribution curve

If you can modify your stored data, use a sentinel value for missing id. A common use case, inferred by the column name, being that id is an integer, strictly greater than zero, you could use 0 as a sentinel value so that you can write

if row['id']:
   regular_process(row)
else:
   special_process(row)

How about a shorthand notation?

{overflow: auto hidden;}

Use QString::arg() for the same effect.

babel module in python has feature to apply commas depending on the locale provided.

To install babel run the below command.

pip install babel

usage

format_currency(1234567.89, 'USD', locale='en_US')
# Output: $1,234,567.89
format_currency(1234567.89, 'USD', locale='es_CO')
# Output: US$ 1.234.567,89 (raw output US$\xa01.234.567,89)
format_currency(1234567.89, 'INR', locale='en_IN')
# Output: ?12,34,567.89

You can simply declare them as local functions in a razor block (i.e. @{}).

@{
    int Add(int x, int y)
    {
        return x + y;
    }
}

<div class="container">
    <p>
        @Add(2, 5)
    </p>
</div>

this is not a regex solution.

alist={"I love ":""He loves"","Je t'aime ":"Il aime","Ich liebe ":"Er liebt"}
for k in alist.keys():
    if k in statement:
       print alist[k],statement.split(k)[1:]

Thanks to the talk with Sarfraz we could figure out the solution.

The problem was that I was passing an HTML element instead of its value, which is actually what I wanted to do (in fact in my php code I need that value as a foreign key for querying my cities table and filter correct entries).

So, instead of:

var data = {
        'mode': 'filter_city',
        'id_A': e[e.selectedIndex]
};

it should be:

var data = {
        'mode': 'filter_city',
        'id_A': e[e.selectedIndex].value
};

Note: check Jason Kulatunga's answer, it quotes JQuery doc to explain why passing an HTML element was causing troubles.

if both databases are on same server and you want to transfer entire table (make copy of it) then use simple select into statement ...

select * into anotherDatabase..copyOfTable from oneDatabase..tableName

You can then write cursor top of sysobjects and copy entire set of tables that way.

If you want more complex data extraction & transformation, then use SSIS and build appropriate ETL in it.

You can not do that...

via css the URL you put on the background-image is just for the image.

Via HTML you have to add the href for your hyperlink in this way:

<a href="http://home.com" id="logo">Your logo</a>

With text-indent and some other css you can adjust your a element to show just the image and clicking on it you will go to your link.

EDIT:

I'm here again to show you and explain why my solution is much better:

<a href="http://home.com" id="logo">Your logo name</a>

This block of HTML is SEO friendly because you have some text inside your link!

How to style it with css:

#logo {
  background-image: url(images/logo.png);
  display: block;
  margin: 0 auto;
  text-indent: -9999px;
  width: 981px;
  height: 180px;
}

Then if you don't care about SEO good to choose the other answer.

I have achieved this by a http API node request which returns required object from node object for HTML page at client ,

for eg: API: localhost:3000/username

returns logged in user from cache by node App object .

node route file,

app.get('/username', function(req, res) {
    res.json({ udata: req.session.user });
    });

In DB2, using single quotes instead of your double quotes will work. So that could translate the same in Oracle..

SELECT CustomerName AS Customer, '' AS Contact 
FROM Customers;

If you had tried all available answers and still cannot find the answer this might solve issue. If you have different solutions configurations like Debug, Release etc then set project output path to 'bin' and compile project. Revert change after compiling.

VS looks for dlls in bin folder

I think this is what you're looking for.

List<String> columnData = new List<String>();

using(SqlConnection connection = new SqlConnection("conn_string"))
{
    connection.Open();
    string query = "SELECT Column1 FROM Table1";
    using(SqlCommand command = new SqlCommand(query, connection))
    {
        using (SqlDataReader reader = command.ExecuteReader())
        {
            while (reader.Read())
            {
                columnData.Add(reader.GetString(0));
            }         
        }
    }
}

Not tested, but this should work fine.

The simplest one got to be:

def html = "http://google.com".toURL().text

In terms of arbitrary code execution, or undesired user passed names, you could have a list of acceptable function/class names, and if the input matches one in the list, it is eval'd.

PS: I know....kinda late....but it's for anyone else who stumbles across this in the future.

You can use this code to get the next month:

$ts = mktime(0, 0, 0, date("n") + 1, 1);
echo date("Y-m-d H:i:s", $ts);
echo date("n", $ts);

Assuming today is 2013-01-31 01:23:45 the above will return:

2013-02-01 00:00:00

One line solution using Linq...

var obj = new {Property1: 1, Property2: 2};
var property1 = obj.GetType().GetProperties().First(o => o.Name == "Property1").GetValue(obj , null);

Note: I did not manually raise OnCollectionChanged in the base methods because it appears only to be possible to create a CollectionChangedEventArgs using the Reset action. If you try to raise OnCollectionChanged using Reset for a single item change, your items control will appear to flicker, which is something you want to avoid.

Try Amateras. It is a very good plugin for generating UML diagrams including class diagram.

You can set max connections using:

set global max_connections = '1 < your number > 100000';

This will set your number of mysql connection unti (Requires SUPER privileges).

From other forums, I have learned that it is due to the MS Update and that a good fix is to simply delete the file MSForms.exd from any Temp subfolder in the user's profile. For instance:

C:\Users\[user.name]\AppData\Local\Temp\Excel8.0\MSForms.exd

C:\Users\[user.name]\AppData\Local\Temp\VBE\MSForms.exd

C:\Users\[user.name]\AppData\Local\Temp\Word8.0\MSForms.exd

Of course the application (Excel, Word...) must be closed in order to delete this file.

You are asking for the value at key 0 of $votes. It is an array that does not contain that key.

The array $votes is not set, so when PHP is trying to access the key 0 of the array, it encounters an undefined offset for [0] and [1] and throws the error.

If you have an array:

$votes = array('1','2','3');

We can now access:

$votes[0];
$votes[1];
$votes[2];

If we try and access:

$votes[3];

We will get the error "Notice: Undefined offset: 3"

I often use an approach with prototypal inheritance. Overriding toString() gives you the advantage that tools like Firebug will log the actual information instead of [object Object] to the console for uncaught exceptions.

Use instanceof to determine the type of exception.

main.js

// just an exemplary namespace
var ns = ns || {};

// include JavaScript of the following
// source files here (e.g. by concatenation)

var someId = 42;
throw new ns.DuplicateIdException('Another item with ID ' +
    someId + ' has been created');
// Firebug console:
// uncaught exception: [Duplicate ID] Another item with ID 42 has been created

Exception.js

ns.Exception = function() {
}

/**
 * Form a string of relevant information.
 *
 * When providing this method, tools like Firebug show the returned 
 * string instead of [object Object] for uncaught exceptions.
 *
 * @return {String} information about the exception
 */
ns.Exception.prototype.toString = function() {
    var name = this.name || 'unknown';
    var message = this.message || 'no description';
    return '[' + name + '] ' + message;
};

DuplicateIdException.js

ns.DuplicateIdException = function(message) {
    this.name = 'Duplicate ID';
    this.message = message;
};

ns.DuplicateIdException.prototype = new ns.Exception();

Yet another method - create a filter function that returns True for all desired tags:

def my_filter(tag):
    return (tag.name == 'a' and
        tag.parent.name == 'li' and
        'test' in tag.parent['class'])

Then just call find_all with the argument:

for a in soup(my_filter): # or soup.find_all(my_filter)
    print a

From the command prompt run the command adb kill-server. This will shutdown ADB and android studio or Eclipse if you were to use that, would show Waiting for ADB as you said.

Once ADB has shutdown down run adb start-server or run adb devices which will automatically start the adb service and show that your android emulator or development devices has successfully connected.

The simplest solution:

1. Don't add the hash key, implement everything else
2. When facebook login is pressed, you will get an error saying "Invalid key hash. The key hash "xxx" does not match any stored key. ..."
3. Open the facebook app dashboard and add the hash "xxx=" ("xxx" hash from the error + "=" sign)

from the terminal u can simply say

expoort FLASK_APP=app_name.py
export FLASK_ENV=development
flask run

or in ur file

if __name__ == "__main__":
    app.run(debug=True)

I recommend using pyenv to manage your local python versions (both 2.x and 3.x) instead of installing new versions directly with homebrew or building new python versions from source manually. Essentially, pyenv can do two key things for you:

• Install different python versions under some directory. Doing pyenv install 3.8.1 will install python 3.8.1 under ~/.pyenv/versions/3.8.1.
• Modify your shell environment (PATH) with shims so that when you do pyenv local 3.8.1, calling python will invoke the new interpreter instead of your system python.

MacOSX Specific Installation

The pyenv repo is pretty detailed on how to install for different systems and what it's actually doing, but here's the basic steps for mac:

1. Install homebrew if you don't already have it and use it to install pyenv with brew install pyenv
2. Once you have pyenv installed, update your .bash_profile file to include:

if command -v pyenv 1>/dev/null 2>&1; then
    eval "$(pyenv init -)"
fi

Now install some python using pyenv and then switch to it with the pyenv local command (you can see all your versions with pyenv versions).

pyenv install 3.8.1 && pyenv local 3.8.1

Note: you may need to create a new shell or reload your bash_profile in your current shell for the pyenv initialization to do its thing (set up shims).

With this setup, you'll be able to keep your system macosx python and switch to whatever new version of python you want available through pyenv.

Try "py" instead of "python" from command line:

C:\Users\Cpsa>py
Python 3.4.1 (v3.4.1:c0e311e010fc, May 18 2014, 10:38:22) [MSC v.1600 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.

Even though too much of CLOSE_WAIT connections means there is something wrong with your code in the first and this is accepted not good practice.

You might want to check out: https://github.com/rghose/kill-close-wait-connections

What this script does is send out the ACK which the connection was waiting for.

This is what worked for me.

It looks like the return value is in an array? That's somewhat strange... and also be aware that certain browsers will allow that to be parsed from a cross-domain request (which isn't true when you have a top-level JSON object).

Anyway, if that is an array wrapper, you'll want something like this:

$('#my-hidden-field').val(theObject[0].id);

You can later retrieve it through a simple .val() call on the same field. This honestly looks kind of strange though. The hidden field won't persist across page requests, so why don't you just keep it in your own (pseudo-namespaced) value bucket? E.g.,

$MyNamespace = $MyNamespace || {};
$MyNamespace.myKey = theObject;

This will make it available to you from anywhere, without any hacky input field management. It's also a lot more efficient than doing DOM modification for simple value storage.

The getRequestURL() omits the port when it is 80 while the scheme is http, or when it is 443 while the scheme is https.

So, just use getRequestURL() if all you want is obtaining the entire URL. This does however not include the GET query string. You may want to construct it as follows then:

StringBuffer requestURL = request.getRequestURL();
if (request.getQueryString() != null) {
    requestURL.append("?").append(request.getQueryString());
}
String completeURL = requestURL.toString();

They're already ints. Why not just use subtraction?

compare = a - b;

Note that Integer.compareTo() doesn't necessarily return only -1, 0 or 1 either.

x = "my_test"
last_char = x.split('').last

The documentation on split() says:

Splits this string around matches of the given regular expression.

(Emphasis mine.)

A dot is a special character in regular expression syntax. Use Pattern.quote() on the parameter to split() if you want the split to be on a literal string pattern:

String[] words = temp.split(Pattern.quote("."));

On http://www.synalysis.net/ you can get the hex editor I'm developing for the Mac - Synalyze It!. It costs 7 € / 40 € (Pro version) and offers some extra features like histogram, incremental search, support of many text encodings and interactive definition of a "grammar" for your file format.

The grammar helps to interpret the files and colors the hex view for easier analysis.

function sample() {
    alert("This is sample function");
}

$(function() {
    $("#button").click(function() {
        setTimeout(sample, 2000);
    });

});

jsFiddle.

If you want to encapsulate sample() there, wrap the whole thing in a self invoking function (function() { ... })().

I was compiling my application targeting any CPU and main problem turned out that adobe reader was installed older v10.x needs to upgrade v11.x, this is the way how I get to resolve this issue.

I think you can use date() function to achive this

$date = '19:24:15 06/13/2013'; 
echo date('h:i:s a m/d/Y', strtotime($date));

This will output

07:24:15 pm 06/13/2013

Live Sample

h is used for 12 digit time
i stands for minutes
s seconds
a will return am or pm (use in uppercase for AM PM)
m is used for months with digits
d is used for days in digit
Y uppercase is used for 4 digit year (use it lowercase for two digit)

Updated

This is with DateTime

$date = new DateTime('19:24:15 06/13/2013');
echo $date->format('h:i:s a m/d/Y') ;

Live Sample

Inserting date in sql

insert
into tablename (timestamp_value)
values ('dd-mm-yyyy hh-mm-ss AM');

If suppose we wanted to insert system date

insert
into tablename (timestamp_value)
values (sysdate);

As you mentioned - it largely depends upon the compiler and the platform. For this, check the ANSI standard, http://home.att.net/~jackklein/c/inttypes.html

Here is the one for the Microsoft compiler: Data Type Ranges.

That header file is not part of the C++ standard, is therefore non-portable, and should be avoided.

Moreover, even if there were some catch-all header in the standard, you would want to avoid it in lieu of specific headers, since the compiler has to actually read in and parse every included header (including recursively included headers) every single time that translation unit is compiled.

An article at zerokspot entitled Custom filebrowser callbacks in CKEditor 3.0 handles this. The most relevant section is quoted below:

So all you have to do from the file browser when you have a file selected is to call this code with the right callback number (normally 1) and the URL of the selected file:

window.opener.CKEDITOR.tools.callFunction(CKEditorFuncNum,url);

For the quick-uploader the process is quite similar. At first I thought that the editor might be listening for a 200 HTTP return code and perhaps look into some header field or something like that to determine the location of the uploaded file, but then - through some Firebug monitoring - I noticed that all that happens after an upload is the following code:

<script type="text/javascript">
window.parent.CKEDITOR.tools.callFunction(CKEditorFuncNum,url, errorMessage); </script>

If the upload failed, set the errorMessage to some non-zero-length string and empty the url, and vice versa on success.

You have to Import the Scanner and Timer Package Properly using the java.util classes.

import java.util.Scanner;
import java.util.Timer;

ngRoute is a basic routing library, where you can specify just one view and controller for any route.

With ui-router, you can specify multiple views, both parallel and nested. So if your application requires (or may require in future) any kind of complex routing/views, then go ahead with ui-router.

This is best getting started guide for AngularUI Router.

You need to include jQueryUI for the extended easing options.

I think there may be an option to only include the easing in the download, or at least just the base library plus easing.

Just remove the ( and the ) on your SELECT statement:

select Name, Subject, student_id, result

I was following the replies, When editing /etc/group I also deleted this line:

ssl-cert:x:112:postgres

then, when trying to install postgresql, I got this error

Preconfiguring packages ...
dpkg: unrecoverable fatal error, aborting:
 syntax error: unknown group 'ssl-cert' in statoverride file
E: Sub-process /usr/bin/dpkg returned an error code (2)

Putting the "ssl-cert:x:112:postgres" line back in /etc/group seems to fix it (so I was able to install postgresql)

Roughly you can do it like that :

try
{
    //do something
}
catch (Exception ex)
{
    string script = "<script>alert('" + ex.Message + "');</script>";
    if (!Page.IsStartupScriptRegistered("myErrorScript"))
    {
         Page.ClientScript.RegisterStartupScript("myErrorScript", script);
    }
}

But I recommend you to define your custom Exception and throw it anywhere you need. At your page catch this custom exception and register your message box script.

For those migrating from WebStorm/PhpStorm,

You could install IntelliJ IDEA Keybindings to keep using almost all the keyboard shortcuts as you did in Webstorm/Phpstorm.

So,

• Duplicate lines => CTRL + D
• Move a line/selection of code Up/Down => Ctrl + Shift + UP/DOWN

Also, here is a list of recommended VS Code extensions that will make your transition from WebStorm/Phpstorm much easier.

You can use a full path with the fstream classes. The folowing code attempts to open the file demo.txt in the root of the C: drive. Note that as this is an input operation, the file must already exist.

#include <fstream>
#include <iostream>
using namespace std;

int main() {
   ifstream ifs( "c:/demo.txt" );       // note no mode needed
   if ( ! ifs.is_open() ) {                 
      cout <<" Failed to open" << endl;
   }
   else {
      cout <<"Opened OK" << endl;
   }
}

What does this code produce on your system?

I guess it is an error caused by not matching name of project and your registered component.

You have inited project with one name, i.e.

react-native init AwesomeApp

But in your index.ios.js file you register other component

AppRegistry.registerComponent('Bananas', () => Bananas);

When it must be

AppRegistry.registerComponent('AwesomeApp', () => Bananas);

If your component name does match, ensure you don't have any other react-native/node process running in another terminal.

File: logdate.aspx

<%@ Page Language="c#" %>

To get that file use the below code.

include(Mage::getBaseDir('skin').'myfunc.php');

But it is not a correct way. To add your custom functions you can use the below file.

app/code/core/Mage/core/functions.php

Kindly avoid to use the PHP function under skin dir.

Not a direct answer, but here is a function to insert a row with column-value pairs into sqlite table:

def sqlite_insert(conn, table, row):
    cols = ', '.join('"{}"'.format(col) for col in row.keys())
    vals = ', '.join(':{}'.format(col) for col in row.keys())
    sql = 'INSERT INTO "{0}" ({1}) VALUES ({2})'.format(table, cols, vals)
    conn.cursor().execute(sql, row)
    conn.commit()

Example of use:

sqlite_insert(conn, 'stocks', {
        'created_at': '2016-04-17',
        'type': 'BUY',
        'amount': 500,
        'price': 45.00})

Note, that table name and column names should be validated beforehand.

Try It....

UpdateModel(book);

var book = new Model.Book
{
    BookNumber =  _book.BookNumber,
    BookName = _book.BookName,
    BookTitle = _book.BookTitle,
};
using (var db = new MyContextDB())
{
    var result = db.Books.SingleOrDefault(b => b.BookNumber == bookNumber);
    if (result != null)
    {
        try
        {
            UpdateModel(book);
            db.Books.Attach(book);
            db.Entry(book).State = EntityState.Modified;
            db.SaveChanges();
        }
        catch (Exception ex)
        {
            throw;
        }
    }
}

I have tried to use the above suggestions and my program crashed, than I figured out the file I'm trying to identify was used and when trying to use 'os.path.getctime' it crashed. what finally worked for me was:

    files_before = glob.glob(os.path.join(my_path,'*'))
    **code where new file is created**
    new_file = set(files_before).symmetric_difference(set(glob.glob(os.path.join(my_path,'*'))))

this codes gets the uncommon object between the two sets of file lists its not the most elegant, and if multiple files are created at the same time it would probably won't be stable

I had same problem but disk space was okay (only 40% full). Problem were inodes, I had too many small files and my inodes were full.

You can check inode status with df -i

In your .gradle change MinSDK, for example:

• build.gradle (Module: app)
  • before: minSdkVersion 9
  • after: minSdkVersion 14

etc.

You can also try to:

telnet example.com 22

to see if you have connectivity to the server. I saw this message and it ended up being the VPN I was on was blocking access. Disconnected from the VPN and I was good to go.

You could try either of these. They are not giving me errors.

It is also the suggested method from typescript for array declaration.

By using the Array<Thing> it is making use of the generics in typescript. It is similar to asking for a List<T> in c# code.

// Declare with default value
private _possessions: Array<Thing> = new Array<Thing>();
// or
private _possessions: Array<Thing> = [];
// or -> prefered by ts-lint
private _possessions: Thing[] = [];

or

// declare
private _possessions: Array<Thing>;
// or -> preferd by ts-lint
private _possessions: Thing[];

constructor(){
    //assign
    this._possessions = new Array<Thing>();
    //or
    this._possessions = [];
}

The thing here is that you're using a for loop outside of your conditional statement.

After the conditions in your IF statement are met you probably navigate to another page, thus when the for loop attempts to iterate once more, you get the stale element error because you're on a different page.

You can add a break at the end of your if statement, this worked for me.

Taking for granted that the JSON you posted is actually what you are seeing in the browser, then the problem is the JSON itself.

The JSON snippet you have posted is malformed.

You have posted:

[{
        "name" : "shopqwe",
        "mobiles" : [],
        "address" : {
            "town" : "city",
            "street" : "streetqwe",
            "streetNumber" : "59",
            "cordX" : 2.229997,
            "cordY" : 1.002539
        },
        "shoe"[{
                "shoeName" : "addidas",
                "number" : "631744030",
                "producent" : "nike",
                "price" : 999.0,
                "sizes" : [30.0, 35.0, 38.0]
            }]

while the correct JSON would be:

[{
        "name" : "shopqwe",
        "mobiles" : [],
        "address" : {
            "town" : "city",
            "street" : "streetqwe",
            "streetNumber" : "59",
            "cordX" : 2.229997,
            "cordY" : 1.002539
        },
        "shoe" : [{
                "shoeName" : "addidas",
                "number" : "631744030",
                "producent" : "nike",
                "price" : 999.0,
                "sizes" : [30.0, 35.0, 38.0]
            }
        ]
    }
]

You could also create your own conversion function, inside which you can use exception blocks:

CREATE OR REPLACE FUNCTION convert_to_integer(v_input text)
RETURNS INTEGER AS $$
DECLARE v_int_value INTEGER DEFAULT NULL;
BEGIN
    BEGIN
        v_int_value := v_input::INTEGER;
    EXCEPTION WHEN OTHERS THEN
        RAISE NOTICE 'Invalid integer value: "%".  Returning NULL.', v_input;
        RETURN NULL;
    END;
RETURN v_int_value;
END;
$$ LANGUAGE plpgsql;

Testing:

=# select convert_to_integer('1234');
 convert_to_integer 
--------------------
               1234
(1 row)

=# select convert_to_integer('');
NOTICE:  Invalid integer value: "".  Returning NULL.
 convert_to_integer 
--------------------

(1 row)

=# select convert_to_integer('chicken');
NOTICE:  Invalid integer value: "chicken".  Returning NULL.
 convert_to_integer 
--------------------

(1 row)

There is opportunity for several improvements (if you are using DbContext):

Set:

yourContext.Configuration.AutoDetectChangesEnabled = false;
yourContext.Configuration.ValidateOnSaveEnabled = false;

Do SaveChanges() in packages of 100 inserts... or you can try with packages of 1000 items and see the changes in performance.

Since during all this inserts, the context is the same and it is getting bigger, you can rebuild your context object every 1000 inserts. var yourContext = new YourContext(); I think this is the big gain.

Doing this improvements in an importing data process of mine, took it from 7 minutes to 6 seconds.

The actual numbers... could not be 100 or 1000 in your case... try it and tweak it.

You are better off using a native array instead of an object literal with number-like properties, so that numbering (as well as numerous other array functions) are taken care of off-the-shelf.

What you are looking for here is an inline interface definition for your array that defines every element in that array, whether initially present or introduced later:

let userTestStatus: { id: number, name: string }[] = [
    { "id": 0, "name": "Available" },
    { "id": 1, "name": "Ready" },
    { "id": 2, "name": "Started" }
];

userTestStatus[34978].nammme; // Error: Property 'nammme' does not exist on type [...]

If you are initializing your array with values right away, the explicit type definition is not a necessity; TypeScript can automatically infer most element types from the initial assignment:

let userTestStatus = [
    { "id": 0, "name": "Available" },
    ...
];

userTestStatus[34978].nammme; // Error: Property 'nammme' does not exist on type [...]

If you are writing code for Node, using Node modules as described by Ivan is without a doubt the way to go.

However, if you need to load JavaScript that has already been written and isn't aware of node, the vm module is the way to go (and definitely preferable to eval).

For example, here is my execfile module, which evaluates the script at path in either context or the global context:

var vm = require("vm");
var fs = require("fs");
module.exports = function(path, context) {
  var data = fs.readFileSync(path);
  vm.runInNewContext(data, context, path);
}

Also note: modules loaded with require(…) don't have access to the global context.

If you want to combine the two most recent commits and just use the older commit's message, you can automate the process using expect.

I assume:

• You're using vi as your editor
• Your commits are one-line each

I tested with git version 2.14.3 (Apple Git-98).

#!/usr/bin/env expect
spawn git rebase -i HEAD~2

# change the second "pick" to "squash"
# down, delete word, insert 's' (for squash), Escape, save and quit
send "jdwis \033:wq\r"

expect "# This is a"

# skip past first commit message (assumed to be one line), delete rest of file
# down 4, delete remaining lines, save and quit
send "4jdG\r:wq\r"

interact

Imagine that this is your Json response

{"Visit":{"VisitId":8,"Description":"visit8"}}

This is how you parse the response and access the values

    Ext.Ajax.request({
    headers: {
        'Content-Type': 'application/json'
    },
    url: 'api/fullvisit/getfullvisit/' + visitId,
    method: 'GET',
    dataType: 'json',
    success: function (response, request) {
        obj = JSON.parse(response.responseText);
        alert(obj.Visit.VisitId);
    }
});

This will alert the VisitId field

You could use the [DataType] attribute on your view model like this:

public class MyViewModel
{
    [DataType(DataType.MultilineText)]
    public string Text { get; set; }
}

and then you could have a controller:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View(new MyViewModel());
    }
}

and a view which does what you want:

@model AppName.Models.MyViewModel
@using (Html.BeginForm())
{
    @Html.EditorFor(x => x.Text)
    <input type="submit" value="OK" />
}

Most answers above will prevent users from adding new lines in a textarea field. If this is something you want to avoid, you can exclude this particular case by checking which element currently has focus :

var keyCode = e.keyCode || e.which;
if (keyCode === 13 && !$(document.activeElement).is('textarea')) {
  e.preventDefault();
  return false;
}

I had the same problem. Here's what I figured out:

=BDP(A1&"@BGN Corp", "Issuer_parent_eqy_ticker")

A1 being the ISINs. This will return the ticker number. Then just use the ticker number to get the price.

This little function has served me well:

    //goto view:
    //useage -  $scope.gotoView("your/path/here", boolean_open_in_new_window)
    $scope.gotoView = function (st_view, is_newWindow)
    {

        console.log('going to view: ' + '#/' + st_view, $window.location);
        if (is_newWindow)
        {
            $window.open($window.location.origin + $window.location.pathname + '' + '#/' + st_view, '_blank');
        }

You dont need the full path, just the view you are switching to

Based on Ali's and Champitoad's answer:

If you want to try different palettes for the same, you can do this in a few lines:

cmap=plt.cm.get_cmap(plt.cm.viridis,143)

^143 being the number of colours you're sampling

I picked 143 because the entire range of colours on the colormap comes into play here. What you can do is sample the nth colour every iteration to get the colormap effect.

n=20 for i,(x,y) in enumerate(points): plt.scatter(x,y,c=cmap(n*i))

If you're working with bullet points, try this:

<ul>
  <li>Coffee</li>
  <li>Tea
    <ul>
      <li>Black tea</li>
      <li>Green tea</li>
    </ul>
  </li>
  <li>Milk</li>
</ul>

This is the method I use when styling markdown.

This is the code what I used for the set selected value

countryList: any = [{ "value": "AF", "group": "A", "text": "Afghanistan"}, { "value": "AL", "group": "A", "text": "Albania"}, { "value": "DZ", "group": "A", "text": "Algeria"}, { "value": "AD", "group": "A", "text": "Andorra"}, { "value": "AO", "group": "A", "text": "Angola"}, { "value": "AR", "group": "A", "text": "Argentina"}, { "value": "AM", "group": "A", "text": "Armenia"}, { "value": "AW", "group": "A", "text": "Aruba"}, { "value": "AU", "group": "A", "text": "Australia"}, { "value": "AT", "group": "A", "text": "Austria"}, { "value": "AZ", "group": "A", "text": "Azerbaijan"}];_x000D_
 _x000D_
 _x000D_
 for (var j = 0; j < countryList.length; j++) {_x000D_
      //debugger_x000D_
      if (countryList[j].text == "Australia") {_x000D_
          console.log(countryList[j].text); _x000D_
          countryList[j].isSelected = 'selected';_x000D_
      }_x000D_
      }

For a couple of years I was a supporter of using a specific .gitignore for IntelliJ with this suggested configuration.

Not anymore.

IntelliJ is updated quite frequently, internal config file specs change more often than I would like and JetBrains flagship excels at auto-configuring itself based on maven/gradle/etc build files.

So my suggestion would be to leave all editor config files out of project and have users configure editor to their liking. Things like code styling can and should be configured at build level; say using Google Code Style or CheckStyle directly on Maven/Gradle/sbt/etc.

This ensures consistency and leaves editor files out of source code that, in my personal opinion, is where they should be.

Using sets will be screaming fast if you have any volume of data

If you are willing to use sets, you have the isdisjoint() method which will check to see if the intersection between your operator list and your other list is empty.

MyOper = set(['AND', 'OR', 'NOT'])
MyList = set(['c1', 'c2', 'NOT', 'c3'])

while not MyList.isdisjoint(MyOper):
    print "No boolean Operator"

http://docs.python.org/library/stdtypes.html#set.isdisjoint

Wouldn't you just change:

numero = stmt.executeUpdate(query);

to:

numero = stmt.executeUpdate(query, Statement.RETURN_GENERATED_KEYS);

Take a look at the documentation for the JDBC Statement interface.

Update: Apparently there is a lot of confusion about this answer, but my guess is that the people that are confused are not reading it in the context of the question that was asked. If you take the code that the OP provided in his question and replace the single line (line 6) that I am suggesting, everything will work. The numero variable is completely irrelevant and its value is never read after it is set.

In addition to @csgillespie's answer, segments is also vectorised to help with this sort of thing:

plot (x, y, ylim=c(0,6))
segments(x,y-sd,x,y+sd)
epsilon <- 0.02
segments(x-epsilon,y-sd,x+epsilon,y-sd)
segments(x-epsilon,y+sd,x+epsilon,y+sd)

You can install it by first extracting all the files from the ISO and then overwriting those files with the files from the ZIP. Then you can run the batch file as administrator to do the installation. Most of the packages install on windows 7, but I haven't tested yet how well they work.

HTML forms support GET and POST. (HTML5 at one point added PUT/DELETE, but those were dropped.)

XMLHttpRequest supports every method, including CHICKEN, though some method names are matched against case-insensitively (methods are case-sensitive per HTTP) and some method names are not supported at all for security reasons (e.g. CONNECT).

Browsers are slowly converging on the rules specified by XMLHttpRequest, but as the other comment pointed out there are still some differences.

According to the javadoc a Scanner does not seem to be intended for reading single characters. You attach a Scanner to an InputStream (or something else) and it parses the input for you. It also can strip of unwanted characters. So you can read numbers, lines, etc. easily. When you need only the characters from your input, use a InputStreamReader for example.

Build cache is generated on application run time when a temporary file automatically generated in dart-tools folder, android folder and iOS folder. Clear command will delete the build tools and dart directories in flutter project so when we re-compile the project it will start from beginning. This command is mostly used when our project is showing debug error or running related error. In this answer we would Clear Build Cache in Flutter Android iOS App and Rebuild Project structure again.

1. Open your flutter project folder in Command Prompt or Terminal. and type flutter clean command and press enter.

2. After executing flutter clean command we would see that it will delete the dart-tools folder, android folder and iOS folder in our application with debug file. This might take some time depending upon your system speed to clean the project.

For more info, see https://flutter-examples.com/clear-build-cache-in-flutter-app/

You should define the struct out of the class like this:

#include <iostream>
using namespace std;
struct X
{
        int v;
};
class E
{
public: 
      X var;
};

int main(){

E object;
object.var.v=10; 

return 0;
}

Similar to above, using filter from dplyr:

filter(df, fct %in% vc)

real problem is that sort sorts things alphanumerically. So if you have a list ['1', '2', '10', '19'] and run sort you get ['1', '10'. '19', '2']. ie 10 comes before 2 because it looks at the first character and sorts starting from that. It seems most methods in python return things in that order. For example if you have a directory named abc with the files labelled as 1.jpg, 2.jpg etc say up to 15.jpg and you do file_list=os.listdir(abc) the file_list is not ordered as you expect but rather as file_list=['1.jpg', '11.jpg'---'15.jpg', '2.jpg]. If the order in which files are processed is important (presumably that's why you named them numerically) the order is not what you think it will be. You can avoid this by using "zeros" padding. For example if you have a list alist=['01', '03', '05', '10', '02','04', '06] and you run sort on it you get the order you wanted. alist=['01', '02' etc] because the first character is 0 which comes before 1. The amount of zeros padding you need is determined by the largest value in the list.For example if the largest is say between 100 and 1000 you need to pad single digits as 001, 002 ---010,011--100, 101 etc.

I tried joonty's answer, but I also got the

exec: 1: not found

error. This is what works best for me (confirmed to work in zsh also):

#!/bin/bash
LOG_FILE=/tmp/both.log
exec > >(tee ${LOG_FILE}) 2>&1
echo "this is stdout"
chmmm 77 /makeError

The file /tmp/both.log afterwards contains

this is stdout
chmmm command not found 

The /tmp/both.log is appended unless you remove the -a from tee.

Hint: >(...) is a process substitution. It lets the exec to the tee command as if it were a file.
