Programs & Examples On #Table lock

I know its late but may help others.

use this in when document indentation is required.

$('document').ready(function()
{
    $('textarea').each(function(){
            $(this).val($(this).val().trim());
        }
    );
});

UPDATE

Now it's available:

Until now it isn't supported, but you can follow the thread for it: GitHub

if you use localhost:

in Facebook-->Settings-->Basic, in field "App Domains" write "localhost", then click to "+Add Platform" choose "Web Site",

it will create two fields "Mobile Site URL" and "Site URL", in "Site URL" write again "localhost".

works for me.

I found a way to do it (dont know if it is the best but it works)

string oldFile = "oldFile.pdf";
string newFile = "newFile.pdf";

// open the reader
PdfReader reader = new PdfReader(oldFile);
Rectangle size = reader.GetPageSizeWithRotation(1);
Document document = new Document(size);

// open the writer
FileStream fs = new FileStream(newFile, FileMode.Create, FileAccess.Write);
PdfWriter writer = PdfWriter.GetInstance(document, fs);
document.Open();

// the pdf content
PdfContentByte cb = writer.DirectContent;

// select the font properties
BaseFont bf = BaseFont.CreateFont(BaseFont.HELVETICA, BaseFont.CP1252,BaseFont.NOT_EMBEDDED);
cb.SetColorFill(BaseColor.DARK_GRAY);
cb.SetFontAndSize(bf, 8);

// write the text in the pdf content
cb.BeginText();
string text = "Some random blablablabla...";
// put the alignment and coordinates here
cb.ShowTextAligned(1, text, 520, 640, 0);
cb.EndText();
cb.BeginText();
text = "Other random blabla...";
// put the alignment and coordinates here
cb.ShowTextAligned(2, text, 100, 200, 0);
cb.EndText();

// create the new page and add it to the pdf
PdfImportedPage page = writer.GetImportedPage(reader, 1);
cb.AddTemplate(page, 0, 0);

// close the streams and voilá the file should be changed :)
document.Close();
fs.Close();
writer.Close();
reader.Close();

I hope this can be usefull for someone =) (and post here any errors)

Yes! You can Debug Android Application While you are developing them follow these steps.. Make sure that you have PC suite of the mobile manufacturer. For Example:if you are using samsung you should have samsung kies

1.Enable USB debugging on your device:Settings > Applications > Development > USB debugging 2.Enable Unknownresources:Settings>Unknowresoures
3.Connect your device to PC
4.Select your Application Right click it: RunAS>Run configurations>Choose Device>Target Select your device Run.

You can also without using debugging cable.For that you need to install Airdroid in your device.After installing enter the link in your browser and Drag and Drop .apk file.

Happy Coding!

Matt Turner's answer is definitely the right answer. However, in the spirit of Ken Williams' answer, you could also do:

capture.output(cat(sdata, sep="")) 

Another approach suitable for overriding a few properties in your test, if you are using @SpringBootTest annotation:

@SpringBootTest(properties = {"propA=valueA", "propB=valueB"})

Thank you for all answers! I found it! It calls "Column selection (for Sublime)" and "Column Mode Editing (for Notepad++)" https://www.sublimetext.com/docs/3/column_selection.html

GPL-compiled ffmpeg can be used from non-GPL program (commercial project) only if it is invoked in the separate process as command line utility; all wrappers that are linked with ffmpeg library (including Microsoft's FFMpegInterop) can use only LGPL build of ffmpeg.

You may try my .NET wrapper for FFMpeg: Video Converter for .NET (I'm an author of this library). It embeds FFMpeg.exe into the DLL for easy deployment and doesn't break GPL rules (FFMpeg is NOT linked and wrapper invokes it in the separate process with System.Diagnostics.Process).

You can make rounded border with width of border of any control in this way:-

CALayer * l1 = [lblName layer];
[l1 setMasksToBounds:YES];
[l1 setCornerRadius:5.0];

// You can even add a border
[l1 setBorderWidth:5.0];
[l1 setBorderColor:[[UIColor darkGrayColor] CGColor]];

Just replace lblName with your UILabel.

Note:- Don't forget to import <QuartzCore/QuartzCore.h>

Try Tixik.com and their API there. They have a very different data that big players, really good coverage mostly in Europe and good API conditions.

In ruby 1.9.3 there is a chainable method called with_index which can be chained to map.

For example:

array.map.with_index { |item, index| ... }

Perhaps you don't have to include the single quotes:

curl --request POST 'http://localhost/Service' --data "path=/xyz/pqr/test/&fileName=1.doc"

Update: Reading curl's manual, you could actually separate both fields with two --data:

curl --request POST 'http://localhost/Service' --data "path=/xyz/pqr/test/" --data "fileName=1.doc"

You could also try --data-binary:

curl --request POST 'http://localhost/Service' --data-binary "path=/xyz/pqr/test/" --data-binary "fileName=1.doc"

And --data-urlencode:

curl --request POST 'http://localhost/Service' --data-urlencode "path=/xyz/pqr/test/" --data-urlencode "fileName=1.doc"

I was able to duplicate your result when trying to run a remote WMI query. The exception thrown is not caught by the Try/Catch, nor will a Trap catch it, since it is not a "terminating error". In PowerShell, there are terminating errors and non-terminating errors . It appears that Try/Catch/Finally and Trap only works with terminating errors.

It is logged to the $error automatic variable and you can test for these type of non-terminating errors by looking at the $? automatic variable, which will let you know if the last operation succeeded ($true) or failed ($false).

From the appearance of the error generated, it appears that the error is returned and not wrapped in a catchable exception. Below is a trace of the error generated.

A work around for your code could be:

Not sure if this helps anyone, but I had the same issue and could not find the process that was holding me up. I closed SSMS and stopped all the services hitting the local instance. Then once I went back in and ran the exec sp_who2, it showed me the culprit. I killed the process and was able to get the Multi_User to work, then restart the services. We had IIS hitting it every few minutes/seconds looking for certain packages.

You should set android:button="@null" instead of "null".

You were soo close!

onclick="doSomething();doSomethingElse();"

But really, you're better off not using onclick at all and attaching the event handler to the DOM node through your Javascript code. This is known as unobtrusive javascript.

As the others have mentioned, useState works - here is how mobx-react-lite implements updates - you could do something similar.

Define a new hook, useForceUpdate -

import { useState, useCallback } from 'react'

export function useForceUpdate() {
  const [, setTick] = useState(0);
  const update = useCallback(() => {
    setTick(tick => tick + 1);
  }, [])
  return update;
}

and use it in a component -

const forceUpdate = useForceUpdate();
if (...) {
  forceUpdate(); // force re-render
}

See https://github.com/mobxjs/mobx-react-lite/blob/master/src/utils.ts and https://github.com/mobxjs/mobx-react-lite/blob/master/src/useObserver.ts

Why not just doing it this way?

DateTime dt1 = new DateTime(2009, 6, 1);
DateTime dt2 = DateTime.Now;
double totalminutes = (dt2 - dt1).TotalMinutes;

Hope this helps.

Of course. In C++, structs and classes are nearly identical (things like defaulting to public instead of private are among the small differences).

when using String array, you have to give size of array while initializing

eg

String[] str = new String[10];

you can use index 0-9 to store values

str[0] = "value1"
str[1] = "value2"
str[2] = "value3"
str[3] = "value4"
str[4] = "value5"
str[5] = "value6"
str[6] = "value7"
str[7] = "value8"
str[8] = "value9"
str[9] = "value10"

if you are using ArrayList instread of string array, you can use it without initializing size of array ArrayList str = new ArrayList();

you can add value by using add method of Arraylist

str.add("Value1");

get retrieve a value from arraylist, you can use get method

String s = str.get(0);

find total number of items by size method

int nCount = str.size();

Most of the answers here are on the right track. However, a row is not a tuple. Tuples* are unordered sets of known values with names. Thus, the following tuples are the same thing (I'm using an imaginary tuple syntax since a relational tuple is largely a theoretical construct):

(x=1, y=2, z=3)
(z=3, y=2, x=1)
(y=2, z=3, x=1)

...assuming of course that x, y, and z are all integers. Also note that there is no such thing as a "duplicate" tuple. Thus, not only are the above equal, they're the same thing. Lastly, tuples can only contain known values (thus, no nulls).

A row** is an ordered set of known or unknown values with names (although they may be omitted). Therefore, the following comparisons return false in SQL:

(1, 2, 3) = (3, 2, 1)
(3, 1, 2) = (2, 1, 3)

Note that there are ways to "fake it" though. For example, consider this INSERT statement:

INSERT INTO point VALUES (1, 2, 3)

Assuming that x is first, y is second, and z is third, this query may be rewritten like this:

INSERT INTO point (x, y, z) VALUES (1, 2, 3)

Or this:

INSERT INTO point (y, z, x) VALUES (2, 3, 1)

...but all we're really doing is changing the ordering rather than removing it.

And also note that there may be unknown values as well. Thus, you may have rows with unknown values:

(1, 2, NULL) = (1, 2, NULL)

...but note that this comparison will always yield UNKNOWN. After all, how can you know whether two unknown values are equal?

And lastly, rows may be duplicated. In other words, (1, 2) and (1, 2) may compare to be equal, but that doesn't necessarily mean that they're the same thing.

If this is a subject that interests you, I'd highly recommend reading SQL and Relational Theory: How to Write Accurate SQL Code by CJ Date.

* Note that I'm talking about tuples as they exist in the relational model, which is a bit different from mathematics in general.

**And just in case you're wondering, just about everything in SQL is a row or table. Therefore, (1, 2) is a row, while VALUES (1, 2) is a table (with one row).

UPDATE: I've expanded a little bit on this answer in a blog post here.

in.next() will return space-delimited strings. Use in.nextLine() if you want to read the whole line. After reading the string, use question = question.replaceAll("\\s","") to remove spaces.

About this I think you can reference to http://docs.oasis-open.org/security/saml/Post2.0/sstc-saml-tech-overview-2.0.html.

Here're my understandings about this, with the Identity Federation Use Case to give a details for those concepts:

• Persistent identifiers-

IdP provides the Persistent identifiers, they are used for linking to the local accounts in SPs, but they identify as the user profile for the specific service each alone. For example, the persistent identifiers are kind of like : johnForAir, jonhForCar, johnForHotel, they all just for one specified service, since it need to link to its local identity in the service.

• Transient identifiers-

Transient identifiers are what IdP tell the SP that the users in the session have been granted to access the resource on SP, but the identities of users do not offer to SP actually. For example, The assertion just like “Anonymity(Idp doesn’t tell SP who he is) has the permission to access /resource on SP”. SP got it and let browser to access it, but still don’t know Anonymity' real name.

• unspecified identifiers-

The explanation for it in the spec is "The interpretation of the content of the element is left to individual implementations". Which means IdP defines the real format for it, and it assumes that SP knows how to parse the format data respond from IdP. For example, IdP gives a format data "UserName=XXXXX Country=US", SP get the assertion, and can parse it and extract the UserName is "XXXXX".

Currently (Swift 2.1) you can check it using 3 ways:

1. Using respondsToSelector answered by @Erik_at_Digit

2. Using '?' answered by @Sulthan

3. And using as? operator:

   if let delegateMe = self.delegate as? YourCustomViewController
   {
      delegateMe.onSuccess()
   }
   

Basically it depends on what you are trying to achieve:

• If for example your app logic need to perform some action and the delegate isn't set or the pointed delegate didn't implement the onSuccess() method (protocol method) so option 1 and 3 are the best choice, though I'd use option 3 which is Swift way.
• If you don't want to do anything when delegate is nil or method isn't implemented then use option 2.

It works fine if you follow the official documentation:

import setuptools
setuptools.setup(...)

Source: https://packaging.python.org/tutorials/packaging-projects/#creating-setup-py

$(".draggable")
.mousedown(function(e){
    $(this).on("mousemove",function(e){
        var p1 = { x: e.pageX, y: e.pageY };
        var p0 = $(this).data("p0") || p1;
        console.log("dragging from x:" + p0.x + " y:" + p0.y + "to x:" + p1.x + " y:" + p1.y);
        $(this).data("p0", p1);
    });
})
.mouseup(function(){
    $(this).off("mousemove");
});

This solution uses the "on" and "off" functions to bind an unbind a mousemove event (bind and unbind are deprecated). You can also detect the change in mouse x and y positions between two mousemove events.

Typically we would place one of these at or near the top of the script. Scripts that parse their command lines would do the redirection after parsing.

Send stdout to a file

exec > file

with stderr

exec > file                                                                      
exec 2>&1

append both stdout and stderr to file

exec >> file
exec 2>&1

As Jonathan Leffler mentioned in his comment:

exec has two separate jobs. The first one is to replace the currently executing shell (script) with a new program. The other is changing the I/O redirections in the current shell. This is distinguished by having no argument to exec.

    <tr bgcolor="#CCC">

      <td width="170">xxxxxx</td>
      <td width="30">xxxxxx</td>
    </tr>
    <tr bgcolor="#FFFFFF">
      <td><?php                 
            $date = date_create($row_Recordset3['fecha']);

            ?></td>
      <td><?php echo $row_Recordset3['descripcion']; ?></td>
      <td><?php echo $row_Recordset3['producto']; ?></td>
      <td><img src="borrar.png" width="14" height="14" class="clickable" onClick="eliminarSeguimiento(<?php echo $row_Recordset3['idSeguimiento']; ?>)" title="borrar"></td>
    </tr>
  </table>

  <input type="hidden" id="datatodisplay" name="datatodisplay">  
    <input type="submit" value="Export to Excel">

?>

Although it's not a command line solution, it may help macos users:

1. Select your PDF files
2. Right-click on your highlighted files
3. Select Quick actions > Create PDF

Your response should be something like this to be qualified as Json Array.

{
  "songs":[
    {"2562862600": {"id":"2562862600", "pos":1}},  
    {"2562862620": {"id":"2562862620", "pos":1}},  
    {"2562862604": {"id":"2562862604", "pos":1}},  
    {"2573433638": {"id":"2573433638", "pos":1}}
  ]
}

You can parse your response as follows

String resp = ...//String output from your source
JSONObject ob = new JSONObject(resp);  
JSONArray arr = ob.getJSONArray("songs");

for(int i=0; i<arr.length(); i++){   
  JSONObject o = arr.getJSONObject(i);  
  System.out.println(o);  
}

This happens because you're trying to serialize the EF object collection directly. Since department has an association to employee and employee to department, the JSON serializer will loop infinetly reading d.Employee.Departments.Employee.Departments etc...

To fix this right before the serialization create an anonymous type with the props you want

example (psuedo)code:

departments.select(dep => new { 
    dep.Id, 
    Employee = new { 
        dep.Employee.Id, dep.Employee.Name 
    }
});

This may also be because you might have given classname with all letters in lowercase something which groovy (know of version 2.5.0) does not support.

class name - User is accepted but user is not.

There is a performance issue related with the left join as well as full join with large data.

In my opinion this is the best solution:

select [First Name], count(1) e from (select * from [Temp Test Data] union all select * from [Temp Test Data 2]) a group by [First Name] having e = 1

Simply add [] to those names like

 <input type="text" class="form-control" placeholder="Titel" name="levels[level][]">
 <input type="text" class="form-control" placeholder="Titel" name="levels[build_time][]">

Take that template and then you can add those even using a loop.

Then you can add those dynamically as much as you want, without having to provide an index. PHP will pick them up just like your expected scenario example.

Edit

Sorry I had braces in the wrong place, which would make every new value as a new array element. Use the updated code now and this will give you the following array structure

levels > level (Array)
levels > build_time (Array)

Same index on both sub arrays will give you your pair. For example

echo $levels["level"][5];
echo $levels["build_time"][5];

You are right. ArrayList.contains() tests equals(), not object identity:

returns true if and only if this list contains at least one element e such that (o==null ? e==null : o.equals(e))

If you got a NullPointerException, verify that you initialized your list, either in a constructor or the declaration. For example:

private List<String> rssFeedURLs = new ArrayList<String>();

A simple workaround is to use Google Spreadsheet. Paste (values only if you have complex formulas) or import the sheet then download CSV. I just tried a few characters and it works rather well.

NOTE: Google Sheets does have limitations when importing. See here.

NOTE: Be careful of sensitive data with Google Sheets.

EDIT: Another alternative - basically they use VB macro or addins to force the save as UTF8. I have not tried any of these solutions but they sound reasonable.

When creating internet shortcuts in Windows, to create the file name, it skips illegal characters, except for forward slash, which is converted to minus.

Basically the error was because I was using old version of aws-sdk and I updated the version so this error occured.

in my case with node js i was using signatureVersion in parmas object like this :

const AWS_S3 = new AWS.S3({
  params: {
    Bucket: process.env.AWS_S3_BUCKET,
    signatureVersion: 'v4',
    region: process.env.AWS_S3_REGION
  }
});

Then I put signature out of params object and worked like charm :

const AWS_S3 = new AWS.S3({
  params: {
    Bucket: process.env.AWS_S3_BUCKET,
    region: process.env.AWS_S3_REGION
  },
  signatureVersion: 'v4'
});

No, but the 32-bit version runs just fine on 64-bit Windows.

Always remember that in case of checked exception you can catch only after throwing the exception(either you throw or any inbuilt method used in your code can throw) ,but in case of unchecked exception You an catch even when you have not thrown that exception.

Since itunesconnect has been changed i am updating with the new steps here.

You have to follow through these steps

1. Login to itunesconnect
2. Choose your app in My Apps section
3. Under Appstore tab choose "Pricing and Availability"
4. Under Availability section click edit will open a popup listing the territories
5. Uncheck all the territories and click Done

You could also try,

OIFS=$IFS;
IFS="\t";

animals=`cat animals.txt`
animalArray=$animals;

for animal in $animalArray
do
    echo $animal
done

IFS=$OIFS;

Buffering of output depends on how your program /homedir/MyScript is implemented. If you find that output is getting buffered, you have to force it in your implementation. For example, use sys.stdout.flush() if it's a python program or use fflush(stdout) if it's a C program.

For docker-compose up (Docker4Drupal)

docker-compose exec php bash

I use Docker for Drupal on a Linux laptop. After running the container I use 'docker-compose exec php bash' to connect with the container so I can run drush commandos. It works fine for me.

It seems that the shortest way is to combine LINQ and string.Concat:

var input = @"My name @is ,Wan.;'; Wan";
var chrs = new[] {'@', ',', '.', ';', '\''};
var result = string.Concat(input.Where(c => !chrs.Contains(c)));
// => result = "My name is Wan Wan" 

See the C# demo. Note that string.Concat is a shortcut to string.Join("", ...).

Note that using a regex to remove individual known chars is still possible to build dynamically, although it is believed that regex is slower. However, here is a way to build such a dynamic regex (where all you need is a character class):

var pattern = $"[{Regex.Escape(new string(chrs))}]+";
var result = Regex.Replace(input, pattern, string.Empty);

See another C# demo. The regex will look like [@,\.;']+ (matching one or more (+) consecutive occurrences of @, ,, ., ; or ' chars) where the dot does not have to be escaped, but Regex.Escape will be necessary to escape other chars that must be escaped, like \, ^, ] or - whose position inside the character class you cannot predict.

I set it to automatically clean up on check-in, which is usually good enough for me. If something is too ugly, I'll just hit the shortcut (Ctrl-Alt-L, Return). And I see they have an option for auto-formatting pasted code, although I've never used that.

I will add this as a reason to locally host these files.

Recently a node in Southern California on TWC has not been able to resolve the ajax.googleapis.com domain (for users with IPv4) only so we are not getting the external files. This has been intermittant up until yesterday (now it is persistant.) Because it was intermittant, I was having tons of problems troubleshooting SaaS user issues. Spent countless hours trying to track why some users were having no issues with the software, and others were tanking. In my usual debugging process I'm not in the habit of asking a user if they have IPv6 turned off.

I stumbled on the issue because I myself was using this particular "route" to the file and also am using only IPV4. I discovered the issue with developers tools telling me jquery wasn't loading, then started doing traceroutes etc... to find the real issue.

After this, I will most likely never go back to externally hosted files because: google doesn't have to go down for this to become a problem, and... any one of these nodes can be compromised with DNS hijacking and deliver malicious js instead of the actual file. Always thought I was safe in that a google domain would never go down, now I know any node in between a user and the host can be a fail point.

To solve the same problem I did set up a small project: http://code.google.com/p/catch-exception/

Using this little helper you would write

verifyException(foo, IndexOutOfBoundsException.class).doStuff();

This is less verbose than the ExpectedException rule of JUnit 4.7. In comparison to the solution provided by skaffman, you can specify in which line of code you expect the exception. I hope this helps.

maybe

var re = /^https?:\/\/[^/]+/i;
window.location.href = re.exec(window.location.href)[0];

is what you're looking for?

The #include <filename> is used when a system file is being referred to. That is a header file that can be found at system default locations like /usr/include or /usr/local/include. For your own files that needs to be included in another program you have to use the #include "filename" syntax.

To mock an ES6 dependency module default export using Jest:

import myModule from '../myModule';
import dependency from '../dependency';

jest.mock('../dependency');

// If necessary, you can place a mock implementation like this:
dependency.mockImplementation(() => 42);

describe('myModule', () => {
  it('calls the dependency once with double the input', () => {
    myModule(2);

    expect(dependency).toHaveBeenCalledTimes(1);
    expect(dependency).toHaveBeenCalledWith(4);
  });
});

The other options didn't work for my case.

No it doesn't wait and the way you are doing it in that sample is not good practice.

dispatch_async is always asynchronous. It's just that you are enqueueing all the UI blocks to the same queue so the different blocks will run in sequence but parallel with your data processing code.

If you want the update to wait you can use dispatch_sync instead.

// This will wait to finish
dispatch_sync(dispatch_get_main_queue(), ^{
    // Update the UI on the main thread.
});

Another approach would be to nest enqueueing the block. I wouldn't recommend it for multiple levels though.

dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
    // Background work

    dispatch_async(dispatch_get_main_queue(), ^{
        // Update UI

        dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
            // Background work

            dispatch_async(dispatch_get_main_queue(), ^{
                // Update UI
            });
        });
    });
});

If you need the UI updated to wait then you should use the synchronous versions. It's quite okay to have a background thread wait for the main thread. UI updates should be very quick.

There is http://ptsv2.com/

"Here you will find a server which receives any POST you wish to give it and stores the contents for you to review."

If your program doesn't have a event loop already, use the sched module, which implements a general purpose event scheduler.

import sched, time
s = sched.scheduler(time.time, time.sleep)
def do_something(sc): 
    print("Doing stuff...")
    # do your stuff
    s.enter(60, 1, do_something, (sc,))

s.enter(60, 1, do_something, (s,))
s.run()

If you're already using an event loop library like asyncio, trio, tkinter, PyQt5, gobject, kivy, and many others - just schedule the task using your existing event loop library's methods, instead.

I just came across this so I am sharing here. Here is the option

You can use:

df.set_value('Row_index', 'Column_name', value)

set_valye is ~100 times faster than .ix method. It also better then use df['Row_index']['Column_name'] = value.

But since set_value is deprecated now so .iat/.at are good replacements.

For example if we have this data_frame

   A   B   C
0  1   8   4 
1  3   9   6
2  22 33  52

if we want to modify the value of the cell [0,"A"] we can do

df.iat[0,0] = 2

or df.at[0,'A'] = 2

Parsing the output of git branch is not recommended, and not a good answer for future readers on Stack Overflow.

1. git branch is what is known as a porcelain command. Porcelain commands are not designed to be machine parsed and the output may change between different versions of Git.
2. There are user configuration options that change the output of git branch in a way that makes it difficult to parse (for instance, colorization). If a user has set color.branch then you will get control codes in the output, this will lead to error: branch 'foo' not found. if you attempt to pipe it into another command. You can bypass this with the --no-color flag to git branch, but who knows what other user configurations might break things.
3. git branch may do other things that are annoying to parse, like put an asterisk next to the currently checked out branch

The maintainer of git has this to say about scripting around git branch output

To find out what the current branch is, casual/careless users may have scripted around git branch, which is wrong. We actively discourage against use of any Porcelain command, including git branch, in scripts, because the output from the command is subject to change to help human consumption use case.

Answers that suggest manually editing files in the .git directory (like .git/refs/heads) are similarly problematic (refs may be in .git/packed-refs instead, or Git may change their internal layout in the future).

Git provides the for-each-ref command to retrieve a list of branches.

Git 2.7.X will introduce the --merged option to so you could do something like the below to find and delete all branches merged into HEAD

for mergedBranch in $(git for-each-ref --format '%(refname:short)' --merged HEAD refs/heads/)
do
    git branch -d ${mergedBranch}
done

Git 2.6.X and older, you will need to list all local branches and then test them individually to see if they have been merged (which will be significantly slower and slightly more complicated).

for branch in $(git for-each-ref --format '%(refname:short)' refs/heads/)
do
    git merge-base --is-ancestor ${branch} HEAD && git branch -d ${branch}
done

Another user mentioned this in slight detail but I missed it until I came back here about 3 times over 2 days -

There is a section titled EventListener breakpoints that contains a list of other breakpoints that can be set. It happens that I accidentally enabled one of them on DOM Mutation that was letting me know whenever anything to the DOM was overridden. Unfortunately this led to me disabling a bunch of plug-ins and add-ons before I realized it was just my machine. Hope this helps someone else.

I would like to share with codes whatever I understood.

The super keyword in java is a reference variable that is used to refer parent class objects. It is majorly used in the following contexts:-

1. Use of super with variables:

class Vehicle 
{ 
    int maxSpeed = 120; 
} 

/* sub class Car extending vehicle */
class Car extends Vehicle 
{ 
    int maxSpeed = 180; 

    void display() 
    { 
        /* print maxSpeed of base class (vehicle) */
        System.out.println("Maximum Speed: " + super.maxSpeed); 
    } 
} 

/* Driver program to test */
class Test 
{ 
    public static void main(String[] args) 
    { 
        Car small = new Car(); 
        small.display(); 
    } 
} 

Output:-

Maximum Speed: 120

2. Use of super with methods:

/* Base class Person */
class Person 
{ 
    void message() 
    { 
        System.out.println("This is person class"); 
    } 
} 

/* Subclass Student */
class Student extends Person 
{ 
    void message() 
    { 
        System.out.println("This is student class"); 
    } 

    // Note that display() is only in Student class 
    void display() 
    { 
        // will invoke or call current class message() method 
        message(); 

        // will invoke or call parent class message() method 
        super.message(); 
    } 
} 

/* Driver program to test */
class Test 
{ 
    public static void main(String args[]) 
    { 
        Student s = new Student(); 

        // calling display() of Student 
        s.display(); 
    } 
}

Output:-

This is student class
This is person class

3. Use of super with constructors:

class Person 
{ 
    Person() 
    { 
        System.out.println("Person class Constructor"); 
    } 
} 

/* subclass Student extending the Person class */
class Student extends Person 
{ 
    Student() 
    { 
        // invoke or call parent class constructor 
        super(); 

        System.out.println("Student class Constructor"); 
    } 
} 

/* Driver program to test*/
class Test 
{ 
    public static void main(String[] args) 
    { 
        Student s = new Student(); 
    } 
} 

Output:-

Person class Constructor
Student class Constructor

FOR MYSQL:

ALTER TABLE `table_name` CHANGE `old_name` `new_name` VARCHAR(255) NOT NULL;

FOR ORACLE:

ALTER TABLE `table_name` RENAME COLUMN `old_name` TO `new_name`;

Sometimes I prefer dynamic objects:

public JsonResult GetJson()
{
  string res;
  WebClient client = new WebClient();

  // Download string
  string value = client.DownloadString("https://api.instagram.com/v1/users/000000000/media/recent/?client_id=clientId");

  // Write values
  res = value;
  dynamic dyn = JsonConvert.DeserializeObject(res);
  var lstInstagramObjects = new List<InstagramModel>();

  foreach(var obj in dyn.data)
  {
    lstInstagramObjects.Add(new InstagramModel()
    {
      Link = (obj.link != null) ? obj.link.ToString() : "",
      VideoUrl = (obj.videos != null) ? obj.videos.standard_resolution.url.ToString() : "",
      CommentsCount = int.Parse(obj.comments.count.ToString()),
      LikesCount = int.Parse(obj.likes.count.ToString()),
      CreatedTime = new System.DateTime(1970, 1, 1, 0, 0, 0, 0).AddSeconds((double.Parse(obj.created_time.ToString()))),
      ImageUrl = (obj.images != null) ? obj.images.standard_resolution.url.ToString() : "",
      User = new InstagramModel.UserAccount()
             {
               username = obj.user.username,
               website = obj.user.website,
               profile_picture = obj.user.profile_picture,
               full_name = obj.user.full_name,
               bio = obj.user.bio,
               id = obj.user.id
             }
    });
  }

  return Json(lstInstagramObjects, JsonRequestBehavior.AllowGet);
}

You can't do this without JavaScript. Stackoverflow is using the jQuery JavaScript library which attachs functions to HTML elements on page load.

Here's how you could do it with vanilla JavaScript:

<textarea onkeydown="if (event.keyCode == 13) { this.form.submit(); return false; }"></textarea>

Keycode 13 is the enter key.

Here's how you could do it with jQuery like as Stackoverflow does:

<textarea class="commentarea"></textarea>

with

$(document).ready(function() {
    $('.commentarea').keydown(function(event) {
        if (event.which == 13) {
            this.form.submit();
            event.preventDefault();
         }
    });
});

I agree with @toskv: I wouldn't recommend to do that:-)

But if you really want to test your private method, you can be aware that the corresponding code for the TypeScript correspond to a method of the constructor function prototype. This means that it can be used at runtime (whereas you will probably have some compilation errors).

For example:

export class FooBar {
  private _status: number;

  constructor( private foo : Bar ) {
    this.initFooBar({});
  }

  private initFooBar(data){
    this.foo.bar( data );
    this._status = this.foo.foo();
  }
}

will be transpiled into:

(function(System) {(function(__moduleName){System.register([], function(exports_1, context_1) {
  "use strict";
  var __moduleName = context_1 && context_1.id;
  var FooBar;
  return {
    setters:[],
    execute: function() {
      FooBar = (function () {
        function FooBar(foo) {
          this.foo = foo;
          this.initFooBar({});
        }
        FooBar.prototype.initFooBar = function (data) {
          this.foo.bar(data);
          this._status = this.foo.foo();
        };
        return FooBar;
      }());
      exports_1("FooBar", FooBar);
    }
  }
})(System);

If you want to convert an Instant to a Date:

Date myDate = Date.from(instant);

And then you can use SimpleDateFormat for the formatting part of your question:

SimpleDateFormat formatter = new SimpleDateFormat("dd MM yyyy HH:mm:ss");
String formattedDate = formatter.format(myDate);

The best you are going to be able to do for now is create an array with an initial count repeating nil:

var sprites = [SKSpriteNode?](count: 64, repeatedValue: nil)

You can then fill in whatever values you want.

In Swift 3.0 :

var sprites = [SKSpriteNode?](repeating: nil, count: 64)

use the attribute data-rel="back" on the anchor tag instead of the hash navigation, this will take you to the previous page

Look at back linking: Here

You can use ARG - see https://docs.docker.com/engine/reference/builder/#arg

The ARG instruction defines a variable that users can pass at build-time to the builder with the docker build command using the --build-arg <varname>=<value> flag. If a user specifies a build argument that was not defined in the Dockerfile, the build outputs an error.

You might be interested in somethinkg like this:

After reading all of the answers I ended up with this version with + a second function to use parameters as flags

function getURLParameter(name) {
    return decodeURIComponent((new RegExp('[?|&]' + name + '=' + '([^&;]+?)(&|#|;|$)','i').exec(location.search)||[,""])[1].replace(/\+/g, '%20'))||null;
}

function isSetURLParameter(name) {
    return (new RegExp('[?|&]' + name + '(?:[=|&|#|;|]|$)','i').exec(location.search) !== null)
}

I believe the correct way of doing it would be to use query builder expressions:

$now = new DateTimeImmutable();
$thirtyDaysAgo = $now->sub(new \DateInterval("P30D"));
$qb->select('e')
   ->from('Entity','e')
   ->add('where', $qb->expr()->between(
            'e.datefield',
            ':from',
            ':to'
        )
    )
   ->setParameters(array('from' => $thirtyDaysAgo, 'to' => $now));

http://docs.doctrine-project.org/en/latest/reference/query-builder.html#the-expr-class

Edit: The advantage this method has over any of the other answers here is that it's database software independent - you should let Doctrine handle the date type as it has an abstraction layer for dealing with this sort of thing.

If you do something like adding a string variable in the form 'Y-m-d' it will break when it goes to a database platform other than MySQL, for example.

What maven does is, it downloads all your project's dependencies into your local repo (.m2 folder). Because of the internet causing issues with your local repo, you project is facing problems. I am not sure if this will surely help you or not but you can try deleting all the files within the repository folder inside the .m2 folder. Since there would be nothing in the local repo, maven would be forced to download the dependencies again, thus forcing an update. Generally, the .m2 folder is located at c:users:[username]:.m2

With EF or LINQ to SQL:

var item = db.Items.OrderByDescending(i => i.Value).FirstOrDefault();

With LINQ to Objects I suggest to use morelinq extension MaxBy (get morelinq from nuget):

var item = items.MaxBy(i => i.Value);

One reason to use object over iframe is that object re-sizes the embedded content to fit the object dimensions. most notable on safari in iPhone 4s where screen width is 320px and the html from the embedded URL may set dimensions greater.

When using instanceof, you need to know the class of B at compile time. When using isAssignableFrom() it can be dynamic and change during runtime.

WinSQL to get last day of last month (i.e today is 2017-02-09, returns 2017-01-31: Select dateadd(day,-day(today()),today())

This is so common but so profoundly wrong. Protobuf data is not string data. It certainly isn't ASCII. You are using the encoding backwards. A text encoding transfers:

• an arbitrary string to formatted bytes
• formatted bytes to the original string

You do not have "formatted bytes". You have arbitrary bytes. You need to use something like a base-n (commonly: base-64) encode. This transfers

• arbitrary bytes to a formatted string
• a formatted string to the original bytes

look at Convert.ToBase64String and Convert. FromBase64String

Exactly, the package you need to install is python-dev.

I think that depth first search solves it. If an unexplored edge leads to a node visited before, then the graph contains a cycle. This condition also makes it O(n), since you can explore maximum n edges without setting it to true or being left with no unexplored edges.

For Linux to allow the edition of a log comment,

• locate the file pre-revprop-change.tmpl in the hooks directory of your repository
• copy the file to the same directory, renaming it to pre-revprop-change
• give execute permission to the file (for the server user, e.g. www-data)

Edited: (thanks to lindes)

• after that you might have to edit the script to return an exit value of 0 for the kind of edits, that you want to allow.

In Arduino:

//temporarily holds data from vals
char charVal[10];                

//4 is mininum width, 3 is precision; float value is copied onto buff
dtostrf(123.234, 4, 3, charVal);

monitor.print("charVal: ");
monitor.println(charVal);

I suppose because you didn't specify plugin version so it triggers the download of associated metadata in order to get the last one.

Otherwise did you try to force local repo usage using -o ?

You need to use the property /a on the set command.

For example,

set /a "c=%a%+%b%"

This allows you to use arithmetic expressions in the set command, rather than simple concatenation.

Your code would then be:

@set a=3
@set b=4
@set /a "c=%a%+%b%"
echo %c%
@set /a "d=%c%+1"
echo %d%

and would output:

7
8

You can stash (save the changes in temporary box) then, back to master branch HEAD.

$ git add .
$ git stash
$ git checkout master

Jump Over Commits Back and Forth:

• Go to a specific commit-sha.

    $ git checkout <commit-sha>
  

• If you have uncommitted changes here then, you can checkout to a new branch | Add | Commit | Push the current branch to the remote.

    # checkout a new branch, add, commit, push
    $ git checkout -b <branch-name>
    $ git add .
    $ git commit -m 'Commit message'
    $ git push origin HEAD          # push the current branch to remote 
  
    $ git checkout master           # back to master branch now
  

• If you have changes in the specific commit and don't want to keep the changes, you can do stash or reset then checkout to master (or, any other branch).

    # stash
    $ git add -A
    $ git stash
    $ git checkout master
  
    # reset
    $ git reset --hard HEAD
    $ git checkout master
  

• After checking out a specific commit if you have no uncommitted change(s) then, just back to master or other branch.

    $ git status          # see the changes
    $ git checkout master
  
    # or, shortcut
    $ git checkout -      # back to the previous state
  

C is more of a hardware programming language, there are easy GUI builders for C, GTK, Glade, etc. The problem is making a program in C that is the easy part, making a GUI that is a easy part, the hard part is to combine both, to interface between your program and the GUI is a headache, and different GUI use different ways, some threw global variables, some use slots. It would be nice to have a GUI builder that would bind easily your C program variables, and outputs. CLI programming is easy when you overcome memory allocation and pointers, GUI you can use a IDE that uses drag and drop. But all around I think it could be simpler.

My Android Studio was not only slow in general use, but also when building.

Here's what I did:

1. Uninstalled Android Studio (Don't delete, uninstall it and check delete the SDK too). Then delete Android folders located in C:\Users\\ folder namely: .android, AndroidStudioX.X
2. Uninstall the SDKs via the SDK manager, remove everything ( If there is lef SDK folder, delete them )
3. Download and Reinstall the latest build for Android Studio (v2.1.2 as of this writing); Install only the SDK/Emulators you need;

It's fast now.

My Story before that:

My laptop sports an Intel Core i7-3612QM and 8gig of ram. When I builded, all the 4 cores/8 threads were on 100% usage. My entire system froze until the ~10 minute wass done. Gradle took me like ~10 unproductive minutes of slow down. This is very annoying. I am using Android Studio since 1.4. There were also tremendous slow down when I copy paste code to and from, selecting menus, right-click context menus, editing manifest, editing gradle files, opening layout files, rendering in the UI Editor, etc. Its was very unusable most of the time.

Due to frustration, I did the above steps. Its fast now. Very usable just as before. I build for only ~20 seconds compare to ~10minutes before that. Also, Android Studio eats about 6gig with emulator and browser with lots of tab open, unlike before its hovering on 98% RAM usage. Not just that, I even saved 45 gigs of space for whatever reason. I only use couple of SDKs and Emulators when I checked the Android SDK folder, it occupies 45gig of space! I think the IDE is having a hard time accessing/IO on my SDK folder.

If you've tried other given solutions and still experiencing the same issue, it may be time to remove Android IDE/SDKs altogether and start anew (it might take you sometime to setup that newly, but its worth it. Considering I've been suffering this sluggishness for months and cost me my productivity).

I really guess that this might be caused by cumulative patches that has been done since then. Or the 45 gig SDK folder on my poorly defragmented drive. I don't know and I could be wrong.

Thank you! HTH

1. Don't use quotation in a field name or table name inside the query.

2. After fetching an object you need to access object attributes/properties (in your case id) by attributes/properties name.

One note: please use mysqli_* or PDO since mysql_* deprecated. Here it is using mysqli:

session_start();
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$link = new mysqli('localhost', 'username', 'password', 'db_name');
$link->set_charset('utf8mb4'); // always set the charset
$name = $_GET["username"];
$stmt = $link->prepare("SELECT id FROM Users WHERE username=? limit 1");
$stmt->bind_param('s', $name);
$stmt->execute();
$result = $stmt->get_result();
$value = $result->fetch_object();
$_SESSION['myid'] = $value->id;

Bonus tips: Use limit 1 for this type of scenario, it will save execution time :)

Try this code,

Create Array List and put value inside that and return it :

private ArrayList f(Button b, final int a)
{
    final ArrayList al = new ArrayList();
    b.addClickHandler(new ClickHandler() {

         @Override
        public void onClick(ClickEvent event) {
             int b = a*5;
             al.add(b);
        }
    });
    return al;
}

When you write List<String> list = new LinkedList();, compiler produces an "unchecked" warning. You may ignore it, but if you used to ignore these warnings you may also miss a warning that notifies you about a real type safety problem.

So, it's better to write a code that doesn't generate extra warnings, and diamond operator allows you to do it in convenient way without unnecessary repetition.

Start with this:

Set fso = CreateObject("Scripting.FileSystemObject")
If (fso.FileExists(path)) Then
   msg = path & " exists."
Else
   msg = path & " doesn't exist."
End If

Taken from the documentation.

Binds a handler to an event (like click) for all current - and future - matched element. Can also bind custom events.

link text

$(function(){
    $(".myclass").live("click", function() {
        // do something
    });
});

My approach is using the attributes collection to add HTML data- attributes from code behind. This is more inline with jquery and client side scripting.

// This would likely be done with findControl in your grid OnItemCreated handler
LinkButton targetBtn = new LinkButton();


// Add attributes
targetBtn.Attributes.Add("data-{your data name here}", value.ToString() );
targetBtn.Attributes.Add("data-{your data name 2 here}", value2.ToString() );

Then retrieve the values through the attribute collection

string val = targetBtn.Attributes["data-{your data name here}"].ToString();

You can use

<?php the_category(', '); ?>

which would output them in a comma separated list.

You can also do the same for tags as well:

<?php the_tags('<em>:</em>', ', ', ''); ?>

I'd say

concat('This is line 1.', 0xd0a, 'This is line 2.')

or

concat(N'This is line 1.', 0xd000a, N'This is line 2.')

I think there is an error in the trigger code. As you want to delete all rows with the deleted patron ID, you have to use old.id (Otherwise it would delete other IDs)

Try this as the new trigger:

CREATE TRIGGER log_patron_delete AFTER DELETE on patrons
FOR EACH ROW
BEGIN
DELETE FROM patron_info
    WHERE patron_info.pid = old.id;
END

Dont forget the ";" on the delete query. Also if you are entering the TRIGGER code in the console window, make use of the delimiters also.

Bear in mind that it is only worth using anything other than a full table scan to find these values if the number of blocks that contain a row that matches the predicate is significantly smaller than the total number of blocks in the table. That is why Oracle will often decline the use of an index in order to full scan when you use LIKE '%x%' where x is a very small string. For example if the optimizer believes that using an index would still require single-block reads on (say) 20% of the table blocks then a full table scan is probably a better option than an index scan.

Sometimes you know that your predicate is much more selective than the optimizer can estimate. In such a case you can look into supplying an optimizer hint to perform an index fast full scan on the relevant column (particularly if the index is a much smaller segment than the table).

SELECT /*+ index_ffs(users (users.last_name)) */
       * 
FROM   users
WHERE  last_name LIKE "%z%"

The line onclick = writeLED(1,1) means that you want to immediately execute the function writeLED(arg1, arg2) with arguments 1, 1 and assign the return value; you need to instead create a function that will execute with those arguments and assign that. The topmost answer gave one example - another is to use the bind() function like so:

    var writeLEDWithSpecifiedArguments = writeLED.bind(this, 1,1);
    document.getElementById('buttonLED'+id).onclick = writeLEDWithSpecifiedArguments;

Try this

var fd = new FormData();
fd.append('fname', 'test.wav');
fd.append('data', soundBlob);
$.ajax({
    type: 'POST',
    url: '/upload.php',
    data: fd,
    processData: false,
    contentType: false
}).done(function(data) {
       console.log(data);
});

You need to use the FormData API and set the jQuery.ajax's processData and contentType to false.

To use aliases on eloquent models modify your code like this:

Item
    ::from( 'items as items_alias' )
    ->join( 'attachments as att', DB::raw( 'att.item_id' ), '=', DB::raw( 'items_alias.id' ) )
    ->select( DB::raw( 'items_alias.*' ) )
    ->get();

This will automatically add table prefix to table names and returns an instance of Items model. not a bare query result. Adding DB::raw prevents laravel from adding table prefixes to aliases.

You can load an XML document into an XMLType, then query it, e.g.:

DECLARE
  x XMLType := XMLType(
    '<?xml version="1.0" ?> 
<person>
   <row>
       <name>Tom</name>
       <Address>
           <State>California</State>
           <City>Los angeles</City>
       </Address>
   </row>
   <row>
       <name>Jim</name>
       <Address>
           <State>California</State>
           <City>Los angeles</City>
       </Address>
   </row>
</person>');
BEGIN
  FOR r IN (
    SELECT ExtractValue(Value(p),'/row/name/text()') as name
          ,ExtractValue(Value(p),'/row/Address/State/text()') as state
          ,ExtractValue(Value(p),'/row/Address/City/text()') as city
    FROM   TABLE(XMLSequence(Extract(x,'/person/row'))) p
    ) LOOP
    -- do whatever you want with r.name, r.state, r.city
  END LOOP;
END;

If you're sure that the OnClickListener instance is applied to a Button, then you could just cast the received view to a Button and get the text:

public void onClick(View view){
Button b = (Button)view;
String text = b.getText().toString();
}

According to Ruskins answer and the comments here I came up with the following (recursive) solution:

public static T GetParentOfType<T>(this Control control) where T : class
{
    if (control?.Parent == null)
        return null;

    if (control.Parent is T parent)
        return parent;

    return GetParentOfType<T>(control.Parent);
}

This is what do you want? DEMO. Try to shrink the browser's window and you'll see that the elements will be ordered.

What I used? Flexible Box Model or Flexbox.

Just add the follow CSS classes to your container element (in this case div#container):

flex-init-setup and flex-ppal-setup.

Where:

1. flex-init-setup means flexbox init setup; and
2. flex-ppal-setup means flexbox principal setup

Here are the CSS rules:

 .flex-init-setup {
     display: -webkit-box;
     display: -moz-box;
     display: -webkit-flex;
     display: -ms-flexbox;
     display: flex;
 }
 .flex-ppal-setup {
     -webkit-flex-flow: column wrap;
     -moz-flex-flow: column wrap;
     flex-flow: column wrap;
     -webkit-justify-content: center;
     -moz-justify-content: center;
     justify-content: center;
 }

Be good, Leonardo

The proposed solutions are interesting and offer a good reference, however they are only partially satisfying. It is ok to manually add the separator when you have a single specific case or you know the format of the input string, but there can be cases where you want to do it programmatically on generic inputs.

With a bit of experimenting, I believe the criteria is that the path delimiter is not added if the first segment is a drive letter, meaning a single letter followed by a colon, no matter if it corresponds to a real unit.

For example:

import os
testval = ['c:','c:\\','d:','j:','jr:','data:']

for t in testval:
    print ('test value: ',t,', join to "folder"',os.path.join(t,'folder'))

test value:  c: , join to "folder" c:folder
test value:  c:\ , join to "folder" c:\folder
test value:  d: , join to "folder" d:folder
test value:  j: , join to "folder" j:folder
test value:  jr: , join to "folder" jr:\folder
test value:  data: , join to "folder" data:\folder

A convenient way to test for the criteria and apply a path correction can be to use os.path.splitdrive comparing the first returned element to the test value, like t+os.path.sep if os.path.splitdrive(t)[0]==t else t.

Test:

for t in testval:
    corrected = t+os.path.sep if os.path.splitdrive(t)[0]==t else t
    print ('original: %s\tcorrected: %s'%(t,corrected),' join corrected->',os.path.join(corrected,'folder'))

original: c:    corrected: c:\  join corrected-> c:\folder
original: c:\   corrected: c:\  join corrected-> c:\folder
original: d:    corrected: d:\  join corrected-> d:\folder
original: j:    corrected: j:\  join corrected-> j:\folder
original: jr:   corrected: jr:  join corrected-> jr:\folder
original: data: corrected: data:  join corrected-> data:\folder

it can be probably be improved to be more robust for trailing spaces, and I have tested it only on windows, but I hope it gives an idea. See also Os.path : can you explain this behavior? for interesting details on systems other then windows.

The tutorial link you provided seems to suggest that you need to set the layout_width and layout_height properties, of your child elements to match_parent.

<ImageView
    android:layout_width="match_parent"
    android:layout_height="match_parent">

I found out how to do this on the Android emulator itself (Menu, "Settings" App - not the settings of the emulator outside). All you need to do is:

open settings app -> Language & Input -> Go to the "Keyboard & Input Methods -> click Default

This will bring up a Dialog in which case you can then disable the Hardware Keyboard by switching the hardware keyboard from on to off. This will disable the Hardware keyboard and enable the softkeyboard.

In Data Source (on the left of Visual Studio) right click on the database, then Configure Data Source With Wizard. A new window will appear, expand the Connection string, you can find the connection string in there

The code below uses HTTP POST to post NSData to a webserver. You also need minor knowledge of PHP.

NSString *urlString = @"http://yourserver.com/upload.php";
NSString *filename = @"filename";
request= [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:@"POST"];
NSString *boundary = @"---------------------------14737809831466499882746641449";
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];
[request addValue:contentType forHTTPHeaderField: @"Content-Type"];
NSMutableData *postbody = [NSMutableData data];
[postbody appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"userfile\"; filename=\"%@.jpg\"\r\n", filename] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[NSData dataWithData:YOUR_NSDATA_HERE]];
[postbody appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:postbody];

NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(@"%@", returnString);

for anyone who get blank page even after making storage accessible for displaying errors put these two lines at first lines of public/index.php to see what is happening at least. for me this error was there :Class 'PDO' not found in /var/www/***/config/database.php on line 16

error_reporting(E_ALL);
ini_set('display_errors', 1);

@Michael Lockwood - you don't need to use the keyword "CALL" anywhere. You just need to mention the procedure call directly.

That is

Begin
   proc1(input1, input2);
end;
/

instead of

Begin
   call proc1(input1, input2);
end;
/

You want

#content div:first-child {
/*css*/
}

You forgot @Service annotation in your service class.

If the first segment doesn't start with / it is a relative route. router.navigate needs a relativeTo parameter for relative navigation

Either you make the route absolute:

this.router.navigate(['/foo-content', 'bar-contents', 'baz-content', 'page'], this.params.queryParams)

or you pass relativeTo

this.router.navigate(['../foo-content', 'bar-contents', 'baz-content', 'page'], {queryParams: this.params.queryParams, relativeTo: this.currentActivatedRoute})

Label's aren't form elements. They don't have a value. They have innerHTML and textContent.

Thus,

$('#telefon').html() 
// or
$('#telefon').text()

or

var telefon = document.getElementById('telefon');
telefon.innerHTML;

If you are starting with your form element, check out the labels list of it. That is,

var el = $('#myformelement');
var label = $( el.prop('labels') );
// label.html();
// el.val();
// blah blah blah you get the idea

These days, socket.on('connect', ...) is not working for me. I use the below code to check at 1st connecting.

if (socket.connected)
  console.log('socket.io is connected.')

and use this code when reconnected.

socket.on('reconnect', ()=>{
  //Your Code Here
});

Just use:

Focus.of(context).unfocus();

Using AddDays(-1) worked for me until I tried to cross months. When I tried to subtract 2 days from 2017-01-01 the result was 2016-00-30. It could not handle the month change correctly (though the year seemed to be fine).

I used date = Convert.ToDateTime(date).Subtract(TimeSpan.FromDays(2)).ToString("yyyy-mm-dd"); and have no issues.

You are assigning to a function call:

invest(initial_amount,top_company(5,year,year+1)) = subsequent_amount

which is illegal in Python. The question is, what do you want to do? What does invest() do? I suppose it returns a value, namely what you're trying to use as subsequent_amount, right?

If so, then something like this should work:

amount = invest(amount,top_company(5,year,year+1),year)

A little late to the party, but this worked for me. Hopefully someone else finds it useful.

<div ng-repeat="video in videos" ng-if="$index < 3">
    ...
</div>

At first, you must specify your path, the path that your *.csv files are in there

path = 'f:\project\dataset'

You can change it based on your system.

then,

use dir function :

files = dir (strcat(path,'\*.csv'))

L = length (files);

for i=1:L
   image{i}=csvread(strcat(path,'\',file(i).name));   
   % process the image in here
end

pwd also can be used.

Try these to clarify the issue of right alignment in float point printing

printf(" 4|%4.1lf\n", 8.9);
printf("04|%04.1lf\n", 8.9);

the output is

 4| 8.9
04|08.9

No, instead you would need to do something like this depending on your needs:

function myFunction(myDate, myString) {
  if(arguments.length > 1 && typeof(Date.parse(myDate)) == "number" && typeof(myString) == "string") {
    //Code here
  }
}

createOrReplaceTempView creates (or replaces if that view name already exists) a lazily evaluated "view" that you can then use like a hive table in Spark SQL. It does not persist to memory unless you cache the dataset that underpins the view.

scala> val s = Seq(1,2,3).toDF("num")
s: org.apache.spark.sql.DataFrame = [num: int]

scala> s.createOrReplaceTempView("nums")

scala> spark.table("nums")
res22: org.apache.spark.sql.DataFrame = [num: int]

scala> spark.table("nums").cache
res23: org.apache.spark.sql.Dataset[org.apache.spark.sql.Row] = [num: int]

scala> spark.table("nums").count
res24: Long = 3

The data is cached fully only after the .count call. Here's proof it's been cached:

Related SO: spark createOrReplaceTempView vs createGlobalTempView

Relevant quote (comparing to persistent table): "Unlike the createOrReplaceTempView command, saveAsTable will materialize the contents of the DataFrame and create a pointer to the data in the Hive metastore." from https://spark.apache.org/docs/latest/sql-programming-guide.html#saving-to-persistent-tables

Note : createOrReplaceTempView was formerly registerTempTable

Firstly, I highly recommend you do your CSS styling in an external CSS file, rather than doing it inline. It's much easier to maintain and can be more reusable using classes.

Working off Alex's answer (& Garret's clearfix) of "adding an element at the end with clear: both", you can do it like so:

    <div id='outerdiv' style='border: 1px solid black; background-color: black;'>
        <div style='width: 300px; border: red 1px dashed; float: left;'>
            <p>xxxxxxxxxxxxxxxxxxxxxxxxxxxxx</p>
        </div>

        <div style='width: 300px; border: red 1px dashed; float: right;'>
            <p>zzzzzzzzzzzzzzzzzzzzzzzzzzzzz</p>
        </div>
        <div style='clear:both;'></div>
    </div>

This works (but as you can see inline CSS isn't so pretty).

This question has been answered properly, but I would like to add my approach, it's not that different than what the others have mentioned.

I use different layouts pages to call different headers/footers, some call this layout, some call it template etc.

1. Edit core/Loader.php and add your own function to load your layout, I called the function e.g.layout.

2. Create your own template page and make it call header/footer for you, I called it default.php and put in a new directory e.g. view/layout/default.php

3. Call your own view page from your controller as you would normally. But instead of calling $this-load->view use $this->load->layout, layout function will call the default.php and default.php will call your header and footer.

1) In core/Loader.php under view() function I duplicated it and added mine

   public function layout($view, $vars = array(), $return = FALSE)
   {
       $vars["display_page"] = $view;//will be called from the layout page
       $layout               = isset($vars["layout"]) ? $vars["layout"] : "default";
       return $this->_ci_load(array('_ci_view' => "layouts/$layout", '_ci_vars' =>  $this->_ci_object_to_array($vars), '_ci_return' => $return));
   }

2) Create layout folder and put default.php in it in view/layout/default.php

   $this->load->view('parts/header');//or wherever your header is
   $this->load->view($display_page);
   $this->load->view('parts/footer');or wherever your footer is

3) From your controller, call your layout

 $this->load->layout('projects');// will use 'view/layout/default.php' layout which in return will call header and footer as well. 

To use another layout, include the new layout name in your $data array

 $data["layout"] = "full_width";
 $this->load->layout('projects', $data);// will use full_width.php layout

and of course you must have your new layout in the layout directory as in:

view/layout/full_width.php 

!important is a part of CSS1.

Browsers supporting it: IE5.5+, Firefox 1+, Safari 3+, Chrome 1+.

It means, something like:

Use me, if there is nothing important else around!

Cant say it better.

To make it more simple, You can use the below plugin.

             <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                        <configuration>
                            <classifier>spring-boot</classifier>
                            <mainClass>
                                com.nirav.certificate.CertificateUtility
                            </mainClass>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

if you want to set jvm args on eclipse you can use below:

see below two links to accomplish it:

1. eclipse setting to pass jvm args to java
2. eclipse setting to pass jvm args to java and adding to run config on eclipse
   

And for Tomcat you can create a setenv.bat file in bin folder of Tomcat and add below lines to it :

echo "hello im starting setenv"
set CATALINA_OPTS=-DNLP.home=${NLP.home} -Dhostname=${hostname}

I just started learning React today and was facing the same problem. Below is the code I had written.

<script type="text/babel">
    class Hello extends React.Component {
        render(){
            return (
                <div>
                    <h1>Hello World</h1>
                </div>
            )
        }
    }
    ReactDOM.render(
        <Hello/>
        document.getElementById('react-container')
    )


</script>

And as you can see that I had missed a comma (,) after I use <Hello/>. And error itself is saying on which line we need to look.

So once I add a comma before the second parameter for the ReactDOM.render() function, all started working fine.

Just to add something noteworthy here. One can define methods of a templated class just fine in the implementation file when they are not function templates.

myQueue.hpp:

template <class T> 
class QueueA {
    int size;
    ...
public:
    template <class T> T dequeue() {
       // implementation here
    }

    bool isEmpty();

    ...
}    

myQueue.cpp:

// implementation of regular methods goes like this:
template <class T> bool QueueA<T>::isEmpty() {
    return this->size == 0;
}


main()
{
    QueueA<char> Q;

    ...
}

That's basically a set of 2 simultaneous equations:

x*y = a
X+y = b

(using the mathematical convention of x and y for the variables to solve and a and b for arbitrary constants).

But the solution involves a quadratic equation (because of the x*y), so depending on the actual values of a and b, there may not be a solution, or there may be multiple solutions.

One problem with sockets is that they do not have a way to flush the buffer. There is something called the Nagle algorithm which collects all data and flushes it after 40ms. So if it is responsiveness and not bandwidth you might be better off with a pipe.

You can disable the Nagle with the socket option TCP_NODELAY but then the reading end will never receive two short messages in one single read call.

So test it, i ended up with none of this and implemented memory mapped based queues with pthread mutex and semaphore in shared memory, avoiding a lot of kernel system calls (but today they aren't very slow anymore).

A wild idea, try parsing it and catch the exception:

import org.json.*;

public boolean isJSONValid(String test) {
    try {
        new JSONObject(test);
    } catch (JSONException ex) {
        // edited, to include @Arthur's comment
        // e.g. in case JSONArray is valid as well...
        try {
            new JSONArray(test);
        } catch (JSONException ex1) {
            return false;
        }
    }
    return true;
}

This code uses org.json JSON API implementation that is available on github, in maven and partially on Android.

ArrayList<File> directories = new ArrayList<File>(
    Arrays.asList(
        new File("your/path/").listFiles(File::isDirectory)
    )
);

You dont have to compile it. the first you use it (import) it is compiled by the CPython interpreter. But if you really want to compile there are several options.

To compile to exe

• py2exe
• cx_Freeze
• py2app

Or 2 compile just a specific *.py file, you can just use

import py_compile
py_compile.compile("yourpythoncode.py")

This Works on Framework 4.0 or Higher. Supports "GO". Also show the error message, line, and sql command.

using System.Data.SqlClient;

        private bool runSqlScriptFile(string pathStoreProceduresFile, string connectionString)
    {

I had a similar issue not long time ago and this was how I solved it

  border-left-color: transparent;_x000D_

  transform: rotate(-45deg);_x000D_
}

Use self if you want to call a method of a class without creating an object/instance of that class, thus saving RAM (sometimes use self for that purpose). In other words, it is actually calling a method statically. Use this for object perspective.

You can use dot notation or bracket notation ...

var obj = {};
obj = {
  "1": "aa",
  "2": "bb"
};

obj.another = "valuehere";
obj["3"] = "cc";

No import is necessary as long as you declare both a.go and b.go to be in the same package. Then, you can use go run to recognize multiple files with:

$ go run a.go b.go

to convert a file to its binary codes(hexadecimal representation) we say:

xxd filename                                         #

e.g:

xxd hello.c                                          #

to see all the contents and codes in a binary file , we could use commands like readelf and objdump, hexdump ,... .

for example if we want to see all the convert all the contents of a binary file(executable, shared libraries, object files) we say:

hexdump binaryfilename

e.g.

hexdump /bin/bash

but readelf is the best utility for analyzing elf(executable and linking format) files. so if we say:

readelf -a /bin/bash

all the contents in the binary file bash would be shown to us, also we could provide different flags for readelf to see all the sections and headers of an elf file separately, for example if we want to see only the elf header we say:

readelf -h /bin/bash

for reading all the segments of the file:

readelf -l /bin/bash

for reading all the sections of the file:

readelf -S /bin/sh

but again as summary , for reading a normal file like "hello.c" and a binary file like bash in path /bin/bash in linux we say:

xxd hello.c

readelf -a /bin/bash

If you're already running the SQL shell, you can use the source command to import data:

use databasename;
source data.sql;

Use this regular expression if you don't want to start with zero:

^[1-9]([0-9]{1,45}$)

If you don't mind starting with zero, use:

^[0-9]{1,45}$

SELECT * from SOME_TABLE where NAME like '%[^A-Z]%'

Or some other expression instead of A-Z

You need to add following lines into your layout for the textview

android:maxLines="1"
android:ellipsize="end"
android:singleLine="true"

Hope this works for you.

Here's a way to do this using TPL. No need to create/dispose of a timer, etc:

void ScheduleSomething()
{

    var runAt = DateTime.Today + TimeSpan.FromHours(16);

    if (runAt <= DateTime.Now)
    {
        DoSomething();
    }
    else
    {
        var delay = runAt - DateTime.Now;
        System.Threading.Tasks.Task.Delay(delay).ContinueWith(_ => DoSomething());
    }

}

void DoSomething()
{
    // do somethig
}

From a mysql datetime/timestamp format:

var dateStr="2011-08-03 09:15:11"; //returned from mysql timestamp/datetime field
var a=dateStr.split(" ");
var d=a[0].split("-");
var t=a[1].split(":");
var date = new Date(d[0],(d[1]-1),d[2],t[0],t[1],t[2]);

I hope is useful for someone. Works in IE FF Chrome

In my case charset, datatype every thing was correct. After investigation I found that in parent table there was no index on foreign key column. Once added problem got solved.

This worked for me:

Check the current role you are logged into by using: SELECT CURRENT_USER, SESSION_USER;

Note: It must match with Owner of the schema.

Schema | Name | Type | Owner
--------+--------+-------+----------

If the owner is different, then give all the grants to the current user role from the admin role by :

GRANT 'ROLE_OWNER' to 'CURRENT ROLENAME';

Then try to execute the query, it will give the output as it has access to all the relations now.

There is now an import functionality on Android ICS 4.0.4.

First you must save your .vcf file on a storage (USB storage, or SDcard). Android will scan the selected storage to detect any .vcf file and will import it on the selected address book. The functionality is in the option menu of your contact list.

!Note: Be careful while doing this! Android will import EVERYTHING that is a .vcf in your storage. It's all or nothing, and the consequence can be trashing your address book.

I believe that by now the above answers are outdated (or at least unclear) so here's my little go at it. I tried compiling ffmpeg with the option --enable-encoders=libx264 and it will give no error but it won't enable anything (I can't seem to find where I found that suggestion).

Anyways step-by-step, first you must compile libx264 yourself because repository version is outdated:

  wget ftp://ftp.videolan.org/pub/x264/snapshots/last_x264.tar.bz2
  tar --bzip2 -xvf last_x264.tar.bz2
  cd x264-snapshot-XXXXXXXX-XXXX/
  ./configure
  make
  sudo make install

And then get and compile ffmpeg with libx264 enabled. I'm using the latest release which is "Happiness":

wget http://ffmpeg.org/releases/ffmpeg-0.11.2.tar.bz2
tar --bzip2 -xvf ffmpeg-0.11.2.tar.bz2
cd ffmpeg-0.11.2/
./configure --enable-libx264 --enable-gpl
make
sudo install

Now finally you have the libx264 codec to encode, to check it you may run

ffmpeg -codecs | grep h264

and you'll see the options you have were the first D means decoding and the first E means encoding

A simple thing you can do is position your fixed DIV relative to the rest of your page with % values.

Check out this jsfiddle here where the fixed DIV is a sidebar.

div#wrapper {
    margin: auto;
    width: 80%;
}

div#main {
    width: 60%;
}

div#sidebar {
    position: fixed;
    width: 30%;
    left: 60%;
}

And a brief picture below describing the layout above:

Does an implicit conversion occur between Task<> and int?

Nope. This is just part of how async/await works.

Any method declared as async has to have a return type of:

• void (avoid if possible)
• Task (no result beyond notification of completion/failure)
• Task<T> (for a logical result of type T in an async manner)

The compiler does all the appropriate wrapping. The point is that you're asynchronously returning urlContents.Length - you can't make the method just return int, as the actual method will return when it hits the first await expression which hasn't already completed. So instead, it returns a Task<int> which will complete when the async method itself completes.

Note that await does the opposite - it unwraps a Task<T> to a T value, which is how this line works:

string urlContents = await getStringTask;

... but of course it unwraps it asynchronously, whereas just using Result would block until the task had completed. (await can unwrap other types which implement the awaitable pattern, but Task<T> is the one you're likely to use most often.)

This dual wrapping/unwrapping is what allows async to be so composable. For example, I could write another async method which calls yours and doubles the result:

public async Task<int> AccessTheWebAndDoubleAsync()
{
    var task = AccessTheWebAsync();
    int result = await task;
    return result * 2;
}

(Or simply return await AccessTheWebAsync() * 2; of course.)

You can't follow the cursor with a DIV, but you can draw a DIV when moving the cursor!

$(document).on('mousemove', function(e){
    $('#your_div_id').css({
       left:  e.pageX,
       top:   e.pageY
    });
});

That div must be off the float, so position: absolute should be set.

This doesn't quite match the OP requirements, though hopefully it helps. With Laravel you can define your rules in an easy-to-maintain format like so:

    $inputs = [
        'email'    => 'foo',
        'password' => 'bar',
    ];

    $rules = [
        'email'    => 'required|email',
        'password' => [
            'required',
            'string',
            'min:10',             // must be at least 10 characters in length
            'regex:/[a-z]/',      // must contain at least one lowercase letter
            'regex:/[A-Z]/',      // must contain at least one uppercase letter
            'regex:/[0-9]/',      // must contain at least one digit
            'regex:/[@$!%*#?&]/', // must contain a special character
        ],
    ];

    $validation = \Validator::make( $inputs, $rules );

    if ( $validation->fails() ) {
        print_r( $validation->errors()->all() );
    }

Would output:

    [
        'The email must be a valid email address.',
        'The password must be at least 10 characters.',
        'The password format is invalid.',
    ]

(The regex rules share an error message by default—i.e. four failing regex rules result in one error message)

I found a list of Java class file versions on the Wikipedia page that describes the class file format:

http://en.wikipedia.org/wiki/Java_class_file#General_layout

Under byte offset 6 & 7, the versions are listed with which Java VM they correspond to.

well, you can do it a lot of ways... one of them is to create a HttpRequest. I would advise you against calling your own webapi from your own MVC (the idea is redundant...) but, here's a end to end tutorial.

If your application's (or any other application's) current directory is the one you're trying to delete, it will not be an access violation error but a directory is not empty. Make sure it's not your own application by changing the current directory; also, make sure the directory is not open in some other program (e.g. Word, excel, Total Commander, etc.). Most programs will cd to the directory of the last file opened, which would cause that.

This is an Oracle-specific notation for an outer join. It means that it will include all rows from t1, and use NULLS in the t0 columns if there is no corresponding row in t0.

In standard SQL one would write:

SELECT t0.foo, t1.bar
  FROM FIRST_TABLE t0
 RIGHT OUTER JOIN SECOND_TABLE t1;

Oracle recommends not to use those joins anymore if your version supports ANSI joins (LEFT/RIGHT JOIN) :

Oracle recommends that you use the FROM clause OUTER JOIN syntax rather than the Oracle join operator. Outer join queries that use the Oracle join operator (+) are subject to the following rules and restrictions […]

I am getting similar errors recently because recent JDKs (and browsers, and the Linux TLS stack, etc.) refuse to communicate with some servers in my customer's corporate network. The reason of this is that some servers in this network still have SHA-1 certificates.

Please see: https://www.entrust.com/understanding-sha-1-vulnerabilities-ssl-longer-secure/ https://blog.qualys.com/ssllabs/2014/09/09/sha1-deprecation-what-you-need-to-know

If this would be your current case (recent JDK vs deprecated certificate encription) then your best move is to update your network to the proper encription technology.

In case that you should provide a temporal solution for that, please see another answers to have an idea about how to make your JDK trust or distrust certain encription algorithms:

How to force java server to accept only tls 1.2 and reject tls 1.0 and tls 1.1 connections

Anyway I insist that, in case that I have guessed properly your problem, this is not a good solution to the problem and that your network admin should consider removing these deprecated certificates and get a new one.

Set and Map are non-linear data structure. List is linear data structure.

The tree data structure SortedSet and SortedMap interfaces implements TreeSet and TreeMap respectively using used Red-Black tree implementation algorithm. So it ensure that there are no duplicated items (or keys in case of Map).

• List is already maintains an ordered collection and index-based data structure, trees are no index-based data structures.
• Tree by definition cannot contain duplicates.
• In List we can have duplicates, so there is no TreeList(i.e. no SortedList).
• List maintains elements in insertion order. So if we want to sort the list we have to use java.util.Collections.sort(). It sorts the specified list into ascending order, according to the natural ordering of its elements.

According to the android documentation, add this in the gradle file of app module.

android {
    ...
    dexOptions {
    preDexLibraries true
    maxProcessCount 8
    }
}

If you are on SQL Server 2008 you can also use

 CRYPT_GEN_RANDOM(2) % 10000

Which seems somewhat simpler (it is also evaluated once per row as newid is - shown below)

DECLARE @foo TABLE (col1 FLOAT)

INSERT INTO @foo SELECT 1 UNION SELECT 2

UPDATE @foo
SET col1 =  CRYPT_GEN_RANDOM(2) % 10000

SELECT *  FROM @foo

Returns (2 random probably different numbers)

col1
----------------------
9693
8573

Mulling the unexplained downvote the only legitimate reason I can think of is that because the random number generated is between 0-65535 which is not evenly divisible by 10,000 some numbers will be slightly over represented. A way around this would be to wrap it in a scalar UDF that throws away any number over 60,000 and calls itself recursively to get a replacement number.

CREATE FUNCTION dbo.RandomNumber()
RETURNS INT
AS
  BEGIN
      DECLARE @Result INT

      SET @Result = CRYPT_GEN_RANDOM(2)

      RETURN CASE
               WHEN @Result < 60000
                     OR @@NESTLEVEL = 32 THEN @Result % 10000
               ELSE dbo.RandomNumber()
             END
  END  

import pandas as pd

dataset = pd.read_csv("data.csv")

edit:

actually, you can just index the dataset like any old array.

dataset = pd.read_csv("data.csv")
first_value = dataset["column name"][0]

Use DATESTR

>> datestr(40189)
ans =
12-Jan-0110

Unfortunately, Excel starts counting at 1-Jan-1900. Find out how to convert serial dates from Matlab to Excel by using DATENUM

>> datenum(2010,1,11)
ans =
      734149
>> datenum(2010,1,11)-40189
ans =
      693960
>> datestr(40189+693960)
ans =
11-Jan-2010

In other words, to convert any serial Excel date, call

datestr(excelSerialDate + 693960)

EDIT

To get the date in mm/dd/yyyy format, call datestr with the specified format

excelSerialDate = 40189;
datestr(excelSerialDate + 693960,'mm/dd/yyyy')
ans =
01/11/2010

Also, if you want to get rid of the leading zero for the month, you can use REGEXPREP to fix things

excelSerialDate = 40189;
regexprep(datestr(excelSerialDate + 693960,'mm/dd/yyyy'),'^0','')
ans =
1/11/2010

The more secure option would be to add allowedHosts to your Webpack config like this:

module.exports = {
devServer: {
 allowedHosts: [
  'host.com',
  'subdomain.host.com',
  'subdomain2.host.com',
  'host2.com'
   ]
  }
};

The array contains all allowed host, you can also specify subdomians. check out more here

SchemaCrawler for PostgreSQL can generate database diagrams from the command line, with the help of GraphViz. You can use regular expressions to include and exclude tables and columns. It can also infer relationships between tables using common naming conventions, if not foreign keys are defined.

Suppose: SqlConnection connectionObj = new SqlConnection()

for : connectionObj.ConnectionString -> use server name : (localdb)\\MSSQLLocalDB.

Note: Double back slash

for : App.config -> use server name : (localdb)\MSSQLLocalDB

Note: Single back slash

I think to be consistant it's nicer to use @throw with your own class that extends NSException. Then you use the same notations for try catch finally:

@try {
.....
}
@catch{
...
}
@finally{
...
}

Apple explains here how to throw and handle exceptions: Catching Exceptions Throwing Exceptions

Here is my current implementation:

public static class UnicodeStringExtensions
{
    public static string EncodeNonAsciiCharacters(this string value) {
        var bytes = Encoding.Unicode.GetBytes(value);
        var sb = StringBuilderCache.Acquire(value.Length);
        bool encodedsomething = false;
        for (int i = 0; i < bytes.Length; i += 2) {
            var c = BitConverter.ToUInt16(bytes, i);
            if ((c >= 0x20 && c <= 0x7f) || c == 0x0A || c == 0x0D) {
                sb.Append((char) c);
            } else {
                sb.Append($"\\u{c:x4}");
                encodedsomething = true;
            }
        }
        if (!encodedsomething) {
            StringBuilderCache.Release(sb);
            return value;
        }
        return StringBuilderCache.GetStringAndRelease(sb);
    }


    public static string DecodeEncodedNonAsciiCharacters(this string value)
      => Regex.Replace(value,/*language=regexp*/@"(?:\\u[a-fA-F0-9]{4})+", Decode);

    static readonly string[] Splitsequence = new [] { "\\u" };
    private static string Decode(Match m) {
        var bytes = m.Value.Split(Splitsequence, StringSplitOptions.RemoveEmptyEntries)
                .Select(s => ushort.Parse(s, NumberStyles.HexNumber)).SelectMany(BitConverter.GetBytes).ToArray();
        return Encoding.Unicode.GetString(bytes);
    }
}

This passes a test:

public void TestBigUnicode() {
    var s = "\U00020000";
    var encoded = s.EncodeNonAsciiCharacters();
    var decoded = encoded.DecodeEncodedNonAsciiCharacters();
    Assert.Equals(s, decoded);
}

with the encoded value: "\ud840\udc00"

This implementation makes use of a StringBuilderCache (reference source link)

You can also check the default buffer size by calling the read only DEFAULT_BUFFER_SIZE attribute from io module.

import io
print (io.DEFAULT_BUFFER_SIZE)

SELECT * FROM my_table;

where my_table is the name of your table.

EDIT:

psql -c "SELECT * FROM my_table"

or just psql and then type your queries.

Wrap your reader in a BufferedReader, which maintains a buffer allowing for much faster reads overall. You can then use read() to read a single character (which you'll need to cast). You can also use readLine() to fetch an entire line and then break that into individual characters. The BufferedReader also supports marking and returning, so if you need to, you can read a line multiple times.

Generally speaking, you want to use a BufferedReader or BufferedInputStream on top of whatever stream you are actually using since the buffer they maintain will make multiple reads much faster.

@mani's response is now slightly outdated as using catch-all '*' routes is no longer supported when using Vue 3 onward. If this is no longer working for you, try replacing the old catch-all path with

{ path: '/:pathMatch(.*)*', component: PathNotFound },

Essentially, you should be able to replace the '*' path with '/:pathMatch(.*)*' and be good to go!

Reason: Vue Router doesn't use path-to-regexp anymore, instead it implements its own parsing system that allows route ranking and enables dynamic routing. Since we usually add one single catch-all route per project, there is no big benefit in supporting a special syntax for *.

Process.Start("explorer.exe" , @"C:\Users");

I had to use this, the other way of just specifying the tgt dir would shut the explorer window when my application terminated.

Here is the official explanation: https://github.com/golang/go/wiki/InterfaceSlice

}

If I am to define the same proptypes for a particular shape multiple times, I like abstract it out to a proptypes file so that if the shape of the object changes, I only have to change the code in one place. It helps dry up the codebase a bit.

Example:

// Inside my proptypes.js file
import PT from 'prop-types';

export const product = {
  id: PT.number.isRequired,
  title: PT.string.isRequired,
  sku: PT.string.isRequired,
  description: PT.string.isRequired,
};


// Inside my component file
import PT from 'prop-types';
import { product } from './proptypes;


List.propTypes = {
  productList: PT.arrayOf(product)
}

Of the solutions you mentioned, none of them appear to give you direct access to the MapKit framework introduced in OS 3.0.

As the Google Maps HTML widgets aren't nearly as good as MapKit (see Google Latitude for an example), you are probably best off developing a native Cocoa touch application, or choosing a solution you can extend to add MapKit integration. PhoneGap is extensible in this manner (it's open-source so it is by default), and some of the other solutions might be as well.

edit: Titanium now has support for MapKit

I think that the URI class is the one that you are looking for.

WPF doesn't have a built-in property to hide the title bar's Close button, but you can do it with a few lines of P/Invoke.

First, add these declarations to your Window class:

private const int GWL_STYLE = -16;
private const int WS_SYSMENU = 0x80000;
[DllImport("user32.dll", SetLastError = true)]
private static extern int GetWindowLong(IntPtr hWnd, int nIndex);
[DllImport("user32.dll")]
private static extern int SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong);

Then put this code in the Window's Loaded event:

var hwnd = new WindowInteropHelper(this).Handle;
SetWindowLong(hwnd, GWL_STYLE, GetWindowLong(hwnd, GWL_STYLE) & ~WS_SYSMENU);

And there you go: no more Close button. You also won't have a window icon on the left side of the title bar, which means no system menu, even when you right-click the title bar - they all go together.

Important note: all this does is hide the button. The user can still close the window! If the user presses Alt+F4, or closes the app via the taskbar, the window will still close.

If you don't want to allow the window to close before the background thread is done, then you could also override OnClosing and set Cancel to true, as Gabe suggested.

You should use:

protected void btn1_Click(object sender, EventArgs e)
{
    Response.Redirect("otherpage.aspx");
}

Imports System.Data

Imports System.Data.SqlClient

Public Class Form2

Dim myconnection As SqlConnection

Dim mycommand As SqlCommand

Dim dr As SqlDataReader

Dim dr1 As SqlDataReader

Dim ra As Integer


Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click


    myconnection = New SqlConnection("server=localhost;uid=root;pwd=;database=simple")

    'you need to provide password for sql server

    myconnection.Open()

    mycommand = New SqlCommand("insert into tbl_cus([name],[class],[phone],[address]) values ('" & TextBox1.Text & "','" & TextBox2.Text & "','" & TextBox3.Text & "','" & TextBox4.Text & "')", myconnection)

    mycommand.ExecuteNonQuery()

    MessageBox.Show("New Row Inserted" & ra)

    myconnection.Close()

End Sub

End Class

For this specific use-case using try..except..else is the cleanest solution, the else clause will be executed if no exception was raised.

NOTE: The else clause must follow all except clauses

for i in iterator:
    try:
        # Do something.
    except:
        # Handle exception
    else:
        # Continue doing something

Maybe the simplest way is:

public MyFragment getVisibleFragment(){
    FragmentManager fragmentManager = MainActivity.this.getSupportFragmentManager();
    List<Fragment> fragments = fragmentManager.getFragments();
    for(Fragment fragment : fragments){
        if(fragment != null && fragment.getUserVisibleHint())
            return (MyFragment)fragment;
    }
    return null;
}

It worked for me

There is a GUI tool available, ASoft .NET Version Detector, which has always proven highly reliable. It can create XML files by specifying the file name of the XML output on the command line.

You could use this for automation. It is a tiny program, written in a non-.NET dependent language and does not require installation.

You simply need to use simpleCart

It is a free and open-source javascript shopping cart that easily integrates with your current website.

You will get the full source code at github

I think this has turned into more of a question of "why follow the spec when browser's don't care." Here is my generalized answer:

Standards are not a "present" thing. They are a "future" thing. If we, as developers, follow web standards, then browser vendors are more likely to correctly implement those standards, and we move closer to a completely interoperable web, where CSS hacks, feature detection, and browser detection are not necessary. Where we don't have to figure out why our layouts break in a particular browser, or how to work around that.

Specifically, if HTML5 does not require using &amp; in your specific situation, and you're using an HTML5 doctype (and also expecting your users to be using HTML5-compliant browsers), then there is no reason to do it.

defaultMember already is an alias - it doesn't need to be the name of the exported function/thing. Just do

import alias from 'my-module';

Alternatively you can do

import {default as alias} from 'my-module';

but that's rather esoteric.
