What you're seeing is integer division. To get floating point division by default,

from __future__ import division

Or, you could convert 1 or 2 of 1/2 into a floating point value.

sqrt = x**(1.0/2)

Remove your nCount altogether (as there are some roots that this algorithm will take many iterations for).

double SqrtNumber(double num)
{
    double lower_bound=0; 
    double upper_bound=num;
    double temp=0;

    while(fabs(num - (temp * temp)) > SOME_SMALL_VALUE)
    {
           temp = (lower_bound+upper_bound)/2;
           if (temp*temp >= num)
           {
                   upper_bound = temp;
           }
           else
           {
                   lower_bound = temp;
           }
    }
    return temp;
 }

On 12 March 2020, a draft has been added by WICG for Text Fragments, and now you can link to text on a page as if you were searching for it by adding the following to the hash

#:~:text=<Text To Link to>

Working example on Chrome Version 81.0.4044.138:

Click on this link Should reload the page and highlight the link's text

This is the one that worked for my case on my current machine (git bash on windows 7):

find ./ -type f -iname "*.cs" -print0 | xargs -0 grep "content pattern"

I always forget the -print0 and -0 for paths with spaces.

EDIT: My preferred tool is now instead ripgrep: https://github.com/BurntSushi/ripgrep/releases . It's really fast and has better defaults (like recursive by default). Same example as my original answer but using ripgrep: rg -g "*.cs" "content pattern"

In your custom view pager adapter, override those methods in ViewPager.

@Override
public boolean onInterceptTouchEvent(MotionEvent event) {
    // Never allow swiping to switch between pages
    return false;
}

@Override
public boolean onTouchEvent(MotionEvent event) {
    // Never allow swiping to switch between pages
    return false;
}

And to enable, just return each super method:

super.onInterceptTouchEvent(event) and super.onTouchEvent(event).

As of Android P, the support libraries have been moved to AndroidX

Please do a refactor for your libs from this page.

https://developer.android.com/topic/libraries/support-library/refactor

you could also change from the .get() method to the .getJSON() method, jQuery will then parse the string returned as data to a javascript object and/or array that you can then reference like any other javascript object/array.

using your code above, if you changed .get to .getJSON, you should get an alert of [object Object] for each element in the array. If you changed the alert to alert(item.name) you will get the names.

This happens to me when I'm using Jinja2 for templates. The problem can be solved by running the development server using the runserver_plus command from django_extensions.

It uses the werkzeug debugger which also happens to be a lot better and has a very nice interactive debugging console. It does some ajax magic to launch a python shell at any frame (in the call stack) so you can debug.

You can just use Tab and Shift+Tab

 private List<String> FindString(String stringToLookFor, List<String> arrayToSearchIn)
 {
     List<String> ReceptacleOfWordsFound = new ArrayList<String>();

     if(!arrayToSearchIn.isEmpty())
     {
         for(String lCurrentString : arrayToSearchIn)
         {
             if(lCurrentString.toUpperCase().contains(stringToLookFor.toUpperCase())
                 ReceptacleOfWordsFound.add(lCurrentString);
         }
     }
  return ReceptacleOfWordsFound;
 }

Use:

public static class StringExtensions
{
    /// <summary>
    /// Cut End. "12".SubstringFromEnd(1) -> "1"
    /// </summary>
    public static string SubstringFromEnd(this string value, int startindex)
    {
        if (string.IsNullOrEmpty(value)) return value;
        return value.Substring(0, value.Length - startindex);
    }
}

I prefer an extension method here for two reasons:

1. I can chain it with Substring. Example: f1.Substring(directorypathLength).SubstringFromEnd(1)
2. Speed.

Issue

Since you are using WebSocket, spender is correct. After recieving the initial data from the WebSocket, you need to send the handshake message from the C# server before any further information can flow.

HTTP/1.1 101 Web Socket Protocol Handshake
Upgrade: websocket
Connection: Upgrade
WebSocket-Origin: example
WebSocket-Location: something.here
WebSocket-Protocol: 13

Something along those lines.

You can do some more research into how WebSocket works on w3 or google.

With modern Git versions, the command to use would be:

git push -u origin <branch_name_test>

This will automatically set the branch name to track from remote and push in one go.

<% %> and <%- and -%> are for any Ruby code, but doesn't output the results (e.g. if statements). the two are the same.

<%= %> is for outputting the results of Ruby code

<%# %> is an ERB comment

Here's a good guide: http://api.rubyonrails.org/classes/ActionView/Base.html

character varying(n), varchar(n) - (Both the same). value will be truncated to n characters without raising an error.

character(n), char(n) - (Both the same). fixed-length and will pad with blanks till the end of the length.

text - Unlimited length.

Example:

Table test:
   a character(7)
   b varchar(7)

insert "ok    " to a
insert "ok    " to b

We get the results:

a        | (a)char_length | b     | (b)char_length
----------+----------------+-------+----------------
"ok     "| 7              | "ok"  | 2

Kindly check Column ApplicationId datatype in Table aspnet_Users , ApplicationId column datatype should be uniqueidentifier .

*Your parameter order is passed wrongly , Parameter @id should be passed as first argument, but in your script it is placed in second argument..*

So error is raised..

Please refere sample script:

DECLARE @id uniqueidentifier
SET @id = NEWID()
Create Table #temp1(AppId uniqueidentifier)

insert into #temp1 values(@id)

Select * from #temp1

Drop Table #temp1

Here's a simple way to test it:

public class OperatorTest {     
    public static void main(String[] args) {
        boolean a = false;
        a &= b();
    }

    private static boolean b() {
        System.out.println("b() was called");
        return true;
    }
}

The output is b() was called, therefore the right-hand operand is evaluated.

So, as already mentioned by others, a &= b is the same as a = a & b.

You may get day, month and year and may concatenate them or may use MM-dd-yyyy format as given below.

Date date1 = new Date();
String mmddyyyy1 = new SimpleDateFormat("MM-dd-yyyy").format(date1);
System.out.println("Formatted Date 1: " + mmddyyyy1);



Date date2 = new Date();
Calendar calendar1 = new GregorianCalendar();
calendar1.setTime(date2);
int day1   = calendar1.get(Calendar.DAY_OF_MONTH);
int month1 = calendar1.get(Calendar.MONTH) + 1; // {0 - 11}
int year1  = calendar1.get(Calendar.YEAR);
String mmddyyyy2 = ((month1<10)?"0"+month1:month1) + "-" + ((day1<10)?"0"+day1:day1) + "-" + (year1);
System.out.println("Formatted Date 2: " + mmddyyyy2);



LocalDateTime ldt1 = LocalDateTime.now();  
DateTimeFormatter format1 = DateTimeFormatter.ofPattern("MM-dd-yyyy");  
String mmddyyyy3 = ldt1.format(format1);  
System.out.println("Formatted Date 3: " + mmddyyyy3);  



LocalDateTime ldt2 = LocalDateTime.now();
int day2 = ldt2.getDayOfMonth();
int mont2= ldt2.getMonthValue();
int year2= ldt2.getYear();
String mmddyyyy4 = ((mont2<10)?"0"+mont2:mont2) + "-" + ((day2<10)?"0"+day2:day2) + "-" + (year2);
System.out.println("Formatted Date 4: " + mmddyyyy4);



LocalDateTime ldt3 = LocalDateTime.of(2020, 6, 11, 14, 30); // int year, int month, int dayOfMonth, int hour, int minute
DateTimeFormatter format2 = DateTimeFormatter.ofPattern("MM-dd-yyyy");  
String mmddyyyy5 = ldt3.format(format2);   
System.out.println("Formatted Date 5: " + mmddyyyy5); 



Calendar calendar2 = Calendar.getInstance();
calendar2.setTime(new Date());
int day3  = calendar2.get(Calendar.DAY_OF_MONTH); // OR Calendar.DATE
int month3= calendar2.get(Calendar.MONTH) + 1;
int year3 = calendar2.get(Calendar.YEAR);
String mmddyyyy6 = ((month3<10)?"0"+month3:month3) + "-" + ((day3<10)?"0"+day3:day3) + "-" + (year3);
System.out.println("Formatted Date 6: " + mmddyyyy6);



Date date3 = new Date();
LocalDate ld1 = LocalDate.parse(new SimpleDateFormat("yyyy-MM-dd").format(date3)); // Accepts only yyyy-MM-dd
int day4  = ld1.getDayOfMonth();
int month4= ld1.getMonthValue();
int year4 = ld1.getYear();
String mmddyyyy7 = ((month4<10)?"0"+month4:month4) + "-" + ((day4<10)?"0"+day4:day4) + "-" + (year4);
System.out.println("Formatted Date 7: " + mmddyyyy7);



Date date4 = new Date();
int day5   = LocalDate.parse(new SimpleDateFormat("yyyy-MM-dd").format(date4)).getDayOfMonth();
int month5 = LocalDate.parse(new SimpleDateFormat("yyyy-MM-dd").format(date4)).getMonthValue();
int year5  = LocalDate.parse(new SimpleDateFormat("yyyy-MM-dd").format(date4)).getYear();
String mmddyyyy8 = ((month5<10)?"0"+month5:month5) + "-" + ((day5<10)?"0"+day5:day5) + "-" + (year5);
System.out.println("Formatted Date 8: " + mmddyyyy8);



Date date5 = new Date();
int day6   = Integer.parseInt(new SimpleDateFormat("dd").format(date5));
int month6 = Integer.parseInt(new SimpleDateFormat("MM").format(date5));
int year6  = Integer.parseInt(new SimpleDateFormat("yyyy").format(date5));
String mmddyyyy9 = ((month6<10)?"0"+month6:month6) + "-" + ((day6<10)?"0"+day6:day6) + "-" + (year6);`enter code here`
System.out.println("Formatted Date 9: " + mmddyyyy9);

Let's try to take an example and understand:

I have a branch, say master, pointing to X <commit-id>, and I have a new branch pointing to Y <sha1>.

Where Y <commit-id> = <master> branch commits - few commits

Now say for Y branch I have to gap-close the commits between the master branch and the new branch. Below is the procedure we can follow:

Step 1:

git checkout -b local origin/new

where local is the branch name. Any name can be given.

Step 2:

  git merge origin/master --no-ff --stat -v --log=300

Merge the commits from master branch to new branch and also create a merge commit of log message with one-line descriptions from at most <n> actual commits that are being merged.

For more information and parameters about Git merge, please refer to:

git merge --help

Also if you need to merge a specific commit, then you can use:

git cherry-pick <commit-id>

Use Expand-Archive cmdlet with one of parameter set:

Expand-Archive -LiteralPath C:\source\file.Zip -DestinationPath C:\destination

Expand-Archive -Path file.Zip -DestinationPath C:\destination

Use mod_rewrite as instructed in this tutorial from the CI wiki.

Provably you already try it, type "false" as follows:

 rawFile.open("GET", file, false);

What I have done in this situation is that I put in the option elements OnClick event like this:

<option onClick="something();">Option Name</option>

Then just create a script function like this:

function something(){
    alert("Hello"); 
    }

UPDATE: Unfortunately I can't comment so I'm updating here
TrueBlueAussie apparently jsfiddle is having some issues, check here if it works or not: http://js.do/code/klm

Note from the author: This is inefficient. But fun, because monoids are awesome. It's not appropriate for production Python code.

>>> sum(l, [])
[1, 2, 3, 4, 5, 6, 7, 8, 9]

This just sums the elements of iterable passed in the first argument, treating second argument as the initial value of the sum (if not given, 0 is used instead and this case will give you an error).

Because you are summing nested lists, you actually get [1,3]+[2,4] as a result of sum([[1,3],[2,4]],[]), which is equal to [1,3,2,4].

Note that only works on lists of lists. For lists of lists of lists, you'll need another solution.

1.) Storage of database passwords Use some kind of hash with a salt and then alter the hash, obfuscate it, for example add a distinct value for each byte. That way your passwords a super secured against dictionary attacks and rainbow tables.

2.) To check if the password matches, create your hash for the password the user put in. Then perform a query against the database for the username and just check if the two password hashes are identical. If they are, give the user an authentication token.

The query should then look like this:

select hashedPassword from users where username=?

Then compare the password to the input.

Further questions?

Try:

count(a/b[.='tsr']/preceding-sibling::*)+1.

Since this question was asked/last answered, support for non string key types for maps for json Marshal/UnMarshal has been added through the use of TextMarshaler and TextUnmarshaler interfaces here. You could just implement these interfaces for your key types and then json.Marshal would work as expected.

package main

import (
    "encoding/json"
    "fmt"
    "strconv"
)

// Num wraps the int value so that we can implement the TextMarshaler and TextUnmarshaler 
type Num int

func (n *Num) UnmarshalText(text []byte) error {
    i, err := strconv.Atoi(string(text))
    if err != nil {
        return err
    }
    *n = Num(i)
    return nil
}

func (n Num) MarshalText() (text []byte, err error) {
    return []byte(strconv.Itoa(int(n))), nil
}

type Foo struct {
    Number Num    `json:"number"`
    Title  string `json:"title"`
}

func main() {
    datas := make(map[Num]Foo)

    for i := 0; i < 10; i++ {
        datas[Num(i)] = Foo{Number: 1, Title: "test"}
    }

    jsonString, err := json.Marshal(datas)
    if err != nil {
        panic(err)
    }

    fmt.Println(datas)
    fmt.Println(jsonString)

    m := make(map[Num]Foo)
    err = json.Unmarshal(jsonString, &m)
    if err != nil {
        panic(err)
    }

    fmt.Println(m)
}

Output:

If you already have a full backup from your database, fortunately, you have an option in SQL Management Studio. In this case, you can use the following steps:

1. Right click on database -> Tasks -> Restore -> Database.

2. In General tab, click on Timeline -> select Specific date and time option.

3. Move the timeline slider to before update command time -> click OK.

4. In the destination database name, type a new name.

5. In the Files tab, check in Reallocate all files to folder and then select a new path to save your recovered database.

6. In the options tab, check in Overwrite ... and remove Take tail-log... check option.

7. Finally, click on OK and wait until the recovery process is over.

I have used this method myself in an operational database and it was very useful.

Use that code it definitely works and I modified it.

Even if that topic is quite old, I'd like to add something. If you overwrite equals for you classes, so it compares your getId, you can use:

customer = new Customer(id);
customers.get(customers.indexOf(customer));

Of course, you'd have to check for an IndexOutOfBounds-Exception, which oculd be translated into a null pointer or a custom CustomerNotFoundException.

This may help someone:

This is a little different than just a global replace

from the terminal we run
node replace.js

replace.js:

function processFile(inputFile, repString = "../") {
var fs = require('fs'),
    readline = require('readline'),
    instream = fs.createReadStream(inputFile),
    outstream = new (require('stream'))(),
    rl = readline.createInterface(instream, outstream);
    formatted = '';   

const regex = /<xsl:include href="([^"]*)" \/>$/gm;

rl.on('line', function (line) {
    let url = '';
    let m;
    while ((m = regex.exec(line)) !== null) {
        // This is necessary to avoid infinite loops with zero-width matches
        if (m.index === regex.lastIndex) {
            regex.lastIndex++;
        }
        
        url = m[1];
    }

    let re = new RegExp('^.* <xsl:include href="(.*?)" \/>.*$', 'gm');

    formatted += line.replace(re, `\t<xsl:include href="${repString}${url}" />`);
    formatted += "\n";
});

rl.on('close', function (line) {
    fs.writeFile(inputFile, formatted, 'utf8', function (err) {
        if (err) return console.log(err);
    });

});
}


// path is relative to where your running the command from
processFile('build/some.xslt');

This is what this does. We have several file that have xml:includes

However in development we need the path to move down a level.

From this

<xsl:include href="common/some.xslt" />

to this

<xsl:include href="../common/some.xslt" />

So we end up running two regx patterns one to get the href and the other to write there is probably a better way to do this but it work for now.

Thanks

I used this and it worked for me in Laravel 5.3.18:

<?php echo URL::to('resources/assets/css/yourcssfile.css') ?>

IMPORTANT NOTE: This will only work when you have already removed "public" from your URL. To do this, you may check out this helpful tutorial.

If you want to append text or html to span then you can do it as below.

$('p span#add_here').append('text goes here');

append will add text to span tag at the end.

to replace entire text or html inside of span you can use .text() or .html()

Approach: 1

Given original string format: 2019/03/04 00:08:48

you can use

updated_df = df['timestamp'].astype('datetime64[ns]')

The result will be in this datetime format: 2019-03-04 00:08:48

Approach: 2

updated_df = df.astype({'timestamp':'datetime64[ns]'})

All title nodes with zipcode or book node as parent:

Version 1:

//title[parent::zipcode|parent::book]

Version 2:

//bookstore/book/title|//bookstore/city/zipcode/title

Version 3: (results are sorted based on source data rather than the order of book then zipcode)

//title[../../../*[book or magazine] or ../../../../*[city/zipcode]]

or - used within true/false - a Boolean operator in xpath

| - a Union operator in xpath that appends the query to the right of the operator to the result set from the left query.

I've found an solution. I use an solution of Steve Gentile, jQuery and ASP.NET MVC – sending JSON to an Action – Revisited.

My ASP.NET MVC view code looks like:

function getplaceholders() {
        var placeholders = $('.ui-sortable');
        var results = new Array();
        placeholders.each(function() {
            var ph = $(this).attr('id');
            var sections = $(this).find('.sort');
            var section;

            sections.each(function(i, item) {
                var sid = $(item).attr('id');
                var o = { 'SectionId': sid, 'Placeholder': ph, 'Position': i };
                results.push(o);
            });
        });
        var postData = { widgets: results };
        var widgets = results;
        $.ajax({
            url: '/portal/Designer.mvc/SaveOrUpdate',
            type: 'POST',
            dataType: 'json',
            data: $.toJSON(widgets),
            contentType: 'application/json; charset=utf-8',
            success: function(result) {
                alert(result.Result);
            }
        });
    };

and my controller action is decorated with an custom attribute

[JsonFilter(Param = "widgets", JsonDataType = typeof(List<PageDesignWidget>))]
public JsonResult SaveOrUpdate(List<PageDesignWidget> widgets

Code for the custom attribute can be found here (the link is broken now).

Because the link is broken this is the code for the JsonFilterAttribute

public class JsonFilter : ActionFilterAttribute
{
    public string Param { get; set; }
    public Type JsonDataType { get; set; }
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        if (filterContext.HttpContext.Request.ContentType.Contains("application/json"))
        {
            string inputContent;
            using (var sr = new StreamReader(filterContext.HttpContext.Request.InputStream))
            {
                inputContent = sr.ReadToEnd();
            }
            var result = JsonConvert.DeserializeObject(inputContent, JsonDataType);
            filterContext.ActionParameters[Param] = result;
        }
    }
}

JsonConvert.DeserializeObject is from Json.NET

You need to use .change() event as well as using # to target element by id:

$('#EventStartTimeMin').change(function() {
    if($(this).val()===""){ 
        console.log('empty');    
    }
});

Fiddle Demo

Don't use the length parameter as it will not work with all browsers. The best way is to set a style on the input tag.

<input style="width:100px" />

This is for fecha(TEXT) format date YYYY-MM-dd HH:mm:ss for instance I want all the records of Ene-05-2014 (2014-01-05):

SELECT 
 fecha 
FROM 
 Mytable 
WHERE 
 DATE(substr(fecha ,1,4) ||substr(fecha ,6,2)||substr(fecha ,9,2))
BETWEEN 
 DATE(20140105) 
AND 
 DATE(20140105);

You can just add a main function to resolve this problem. Just like:

int main()
{
    return 0;
}

for iOS 8 and above

UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge|UIUserNotificationTypeSound|UIUserNotificationTypeAlert) categories:nil];
[application registerUserNotificationSettings:settings];

You can combine the check and cast into one statement:

let touch = object.anyObject() as UITouch
if let picker = touch.view as? UIPickerView {
    ...
}

Then you can use picker within the if block.

For me, such tags are enabled by default. You can configure which task tags should be used in the workspace options: Java > Compiler > Task tags

Check if they are enabled in this location, and that should be enough to have them appear in the Task list (or the Markers view).

Extra note: reinstalling Eclipse won't change anything most of the time if you work on the same workspace. Most settings used by Eclipse are stored in the .metadata folder, in your workspace folder.

You can find the info here: http://www.php.net/manual/en/language.operators.comparison.php

It's scarce because it wasn't added until PHP4. What you have is fine though, if you know there may be a type difference then it's a much better comparison, since it's testing value and type in the comparison, not just value.

I know this post is old. But after gathering all code from above I made a nice method (solution) to handle ajax running and regular pages. The code is made for C# only (since Selenium is definitely a best fit for C# Visual Studio after a year of messing around).

The method is used as an extension method, which means to put it simple; that you can add more functionality (methods) in this case, to the object IWebDriver. Important is that you have to define: 'this' in the parameters to make use of it.

The timeout variable is the amount of seconds for the webdriver to wait, if the page is not responding. Using 'Selenium' and 'Selenium.Support.UI' namespaces it is possible to execute a piece of javascript that returns a boolean, whether the document is ready (complete) and if jQuery is loaded. If the page does not have jQuery then the method will throw an exception. This exception is 'catched' by error handling. In the catch state the document will only be checked for it's ready state, without checking for jQuery.

public static void WaitUntilDocumentIsReady(this IWebDriver driver, int timeoutInSeconds) {
    var javaScriptExecutor = driver as IJavaScriptExecutor;
    var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(timeoutInSeconds));

    try {
        Func<IWebDriver, bool> readyCondition = webDriver => (bool)javaScriptExecutor.ExecuteScript("return (document.readyState == 'complete' && jQuery.active == 0)");
        wait.Until(readyCondition);
    } catch(InvalidOperationException) {
        wait.Until(wd => javaScriptExecutor.ExecuteScript("return document.readyState").ToString() == "complete");
    }
}

Maybe like that:

[HttpPost]
public ActionResult Register(Member member)
{
    try
    {
       if (!ModelState.IsValid)
       {
          ModelState.AddModelError("keyName", "Form is not valid");
          return View();
       }
       MembersManager.RegisterMember(member);
    }
    catch (Exception ex)
    {
       ModelState.AddModelError("keyName", ex.Message);
       return View(member);
    }
}

And in display add:

<div class="alert alert-danger">
  @Html.ValidationMessage("keyName")
</div>

OR

<div class="alert alert-danger">
  @Html.ValidationSummary(false)
</div>

Existing solution

The shortest and probably the fastest solution is:

from math import factorial
print factorial(1000)

Building your own

You can also build your own solution. Generally you have two approaches. The one that suits me best is:

from itertools import imap
def factorial(x):
    return reduce(long.__mul__, imap(long, xrange(1, x + 1)))

print factorial(1000)

(it works also for bigger numbers, when the result becomes long)

The second way of achieving the same is:

def factorial(x):
    result = 1
    for i in xrange(2, x + 1):
        result *= i
    return result

print factorial(1000)

My solution is trigger from a real touch event in a prior menu. They don't force you to use a specific player interface of course. For my purposes, this works well. If you don't have an existing interface to use, afaik you're buggered. Maybe you could try tilt events or something...

5 Major differences between Kafka and RabbitMQ, customer who are using them:

Which messaging system to choose or should we change our existing messaging system??

There is no one answer to above question. One possible approach to review when you have to decide which messaging system or should you change existing system is to “Evaluate scope and cost?”

select GROUP_CONCAT(stat SEPARATOR ' ') from (select concat('KILL ',id,';') as stat from information_schema.processlist) as stats;

Then copy and paste the result back into the terminal. Something like:

KILL 2871; KILL 2879; KILL 2874; KILL 2872; KILL 2866;

While the accepted and most upvoted answer is great, I additionally find it useful trying to explain the difference only by words:

merge

• “okay, we got two differently developed states of our repository. Let's merge them together. Two parents, one resulting child.”

rebase

• “Give the changes of the main branch (whatever its name) to my feature branch. Do so by pretending my feature work started later, in fact on the current state of the main branch.”
• “Rewrite the history of my changes to reflect that.” (need to force-push them, because normally versioning is all about not tampering with given history)
• “Likely —if the changes I raked in have little to do with my work— history actually won't change much, if I look at my commits diff by diff (you may also think of ‘patches’).“

summary: When possible, rebase is almost always better. Making re-integration into the main branch easier.

Because? ? your feature work can be presented as one big ‘patch file’ (aka diff) in respect to the main branch, not having to ‘explain’ multiple parents: At least two, coming from one merge, but likely many more, if there were several merges. Unlike merges, multiple rebases do not add up. (another big plus)

try this:

Int i = Long.valueOf(L)// L: Long Value

Use pd.concat to merge a list of DataFrame into a single big DataFrame.

appended_data = []
for infile in glob.glob("*.xlsx"):
    data = pandas.read_excel(infile)
    # store DataFrame in list
    appended_data.append(data)
# see pd.concat documentation for more info
appended_data = pd.concat(appended_data)
# write DataFrame to an excel sheet 
appended_data.to_excel('appended.xlsx')

The "\z" COMMAND is also a good way to list tables when inside the interactive psql session.

eg.

# psql -d mcdb -U admin -p 5555
mcdb=# /z
                           Access privileges for database "mcdb"

On Arch Linux you will need to install postgresql-libs:

sudo pacman -Syu postgresql-libs

:: savevars.bat
:: Use $ to prefix any important variable to save it for future runs.

@ECHO OFF
SETLOCAL

REM Load variables
IF EXIST config.txt FOR /F "delims=" %%A IN (config.txt) DO SET "%%A"

REM Change variables
IF NOT DEFINED $RunCount (
    SET $RunCount=1
) ELSE SET /A $RunCount+=1

REM Display variables
SET $

REM Save variables
SET $>config.txt

ENDLOCAL
PAUSE
EXIT /B

Output:

$RunCount=1

$RunCount=2

$RunCount=3

The technique outlined above can also be used to share variables among multiple batch files.

I had the same problem now with testing code. That was caused in spring boot because of the @RunWith annotation. I have used:

@RunWith(SpringRunner.class)

With that annotation there is JUnit Vintage running which can't find any tests and gives you the error. I have removed that and only JUnit Jupiter is running and everything is fine.

Use border-collapse and border-spacing to get spaces between the table cells. I would not recommend using floating cells as suggested by QQping.

JSFiddle

If you dont need the whole Type variable and just want to check the type you can easily create a temp variable and use is operator.

T checkType = default(T);

if (checkType is MyClass)
{}

You can simply add following file to your tests directory, and then python will run it before the tests

__init__.py file

import os
import sys
sys.path.insert(0, os.path.abspath(os.path.join(os.path.dirname(__file__), '..')))

Try this function instead.

string source = "My name is Marco and I'm from Italy";
string[] stringSeparators = new string[] {"is Marco and"};
var result = source.Split(stringSeparators, StringSplitOptions.None);

I solved the problem by uninstalling NodeJs and gulp then re-installing both again.

To install gulp globally I executed the following command

npm install -g gulp

If your python >= 3.6, F-string formatted literal is your new friend.

It's more simple, clean, and better performance.

UILabel *lbl1 = [[UILabel alloc] init];
/*important--------- */lbl1.textColor = [UIColor blackColor];

Primarily what that means is that there are too many concurrent requests and further that they exceed the default 1000 queued requests. That is there are 1000 or more queued requests to your website.

This could happen (assuming there are no faults in your app) if there are long running tasks and as a result the Request queue is backed up.

Depending on how the application pool has been set up you may see this kind of thing. Typically, the app pool's Process Model has an item called Maximum Worker Processes. By default this is 1. If you set it to more than 1 (typically up to a max of the number of cores on the hardware) you may not see this happen.

Just to note that unless the site is extremely busy you should not see this. If you do, it's really pointing to long running tasks

Many ways to do this. ismember is the first that comes to mind, since it is a set membership action you wish to take. Thus

X = primes(20);
ismember([15 17],X)
ans =
      0    1

Since 15 is not prime, but 17 is, ismember has done its job well here.

Of course, find (or any) will also work. But these are not vectorized in the sense that ismember was. We can test to see if 15 is in the set represented by X, but to test both of those numbers will take a loop, or successive tests.

~isempty(find(X == 15))
~isempty(find(X == 17))

or,

any(X == 15)
any(X == 17)

Finally, I would point out that tests for exact values are dangerous if the numbers may be true floats. Tests against integer values as I have shown are easy. But tests against floating point numbers should usually employ a tolerance.

tol = 10*eps;
any(abs(X - 3.1415926535897932384) <= tol)

ALTER IGNORE TABLE test
           ADD UNIQUE INDEX 'test' ('b'); 

@ here 'b' is column name to uniqueness, @ here 'test' is index name.

You need to store the first run time of the program in order to do this. How I'd probably do it is using the built in application settings in visual studio. Make one called InstallDate which is a User Setting and defaults to DateTime.MinValue or something like that (e.g. 1/1/1900).

Then when the program is run the check is simple:

if (appmode == "trial")
{
  // If the FirstRunDate is MinValue, it's the first run, so set this value up
  if (Properties.Settings.Default.FirstRunDate == DateTime.MinValue)
  {
    Properties.Settings.Default.FirstRunDate = DateTime.Now;
    Properties.Settings.Default.Save(); 
  }

  // Now check whether 30 days have passed since the first run date
  if (Properties.Settings.Default.FirstRunDate.AddMonths(1) < DateTime.Now)
  {
    // Do whatever you want to do on expiry (exception message/shut down/etc.)
  }
}

User settings are stored in a pretty weird location (something like C:\Documents and Settings\YourName\Local Settings\Application Data) so it will be pretty hard for average joe to find it anyway. If you want to be paranoid, just encrypt the date before saving it to settings.

EDIT: Sigh, misread the question, not as complex as I thought >.>

(MacOS) I got this issue after getting some malware that was forcing me to use WeKnow as a search engine. To fix this on MacOs I followed these steps

1. Go to System Preferences, then check if there's an icon named Profiles.

2. Remove AdminPrefs profile

3. Change default search engine settings, Restart Chrome

The above partially helped (I still had WeKnow as my home page). After that I followed these steps:

1. Type chrome://policy/ to see the policies. You cannot change them there

2. Copy paste this into your terminal

defaults write com.google.Chrome HomepageIsNewTabPage -bool false

defaults write com.google.Chrome NewTabPageLocation -string "https://www.google.com/"

defaults write com.google.Chrome HomepageLocation -string "https://www.google.com/"

defaults delete com.google.Chrome DefaultSearchProviderSearchURL

defaults delete com.google.Chrome DefaultSearchProviderNewTabURL

defaults delete com.google.Chrome DefaultSearchProviderName

I've also ran a scan of my system with Avast antivirus that has detected some malware

Ensure these two and it should work:-

1. Python, Oracle instantclient and cx_Oracle are 32 bit.
2. Set the environment variables.

Fixes this issue on windows like a charm.

Call HttpURLConnection.setRequestMethod("POST") and HttpURLConnection.setDoOutput(true); Actually only the latter is needed as POST then becomes the default method.

I use something similar, but with opposite logic, in a lot of my functions.

DWORD dwError = ERROR_SUCCESS;

do
{
    if ( (dwError = SomeFunction()) != ERROR_SUCCESS )
    {
         /* handle error */
         continue;
    }

    if ( (dwError = SomeOtherFunction()) != ERROR_SUCCESS )
    {
         /* handle error */
         continue;
    }
}
while ( 0 );

if ( dwError != ERROR_SUCCESS )
{
    /* resource cleanup */
}

String.prototype.match returns an array, we can then check the length,

I find this method to be most descriptive

var str = 'one two three four five';

str.match(/\w+/g).length;

To dynamically change the color of a text box goto properties, goto font/Color and set the following expression

=SWITCH(Fields!CurrentRiskLevel.Value = "Low", "Green",
Fields!CurrentRiskLevel.Value = "Moderate", "Blue",
Fields!CurrentRiskLevel.Value = "Medium", "Yellow",
Fields!CurrentRiskLevel.Value = "High", "Orange",
Fields!CurrentRiskLevel.Value = "Very High", "Red"
)

Same way for tolerance

=SWITCH(Fields!Tolerance.Value = "Low", "Red",
Fields!Tolerance.Value = "Moderate", "Orange",
Fields!Tolerance.Value = "Medium", "Yellow",
Fields!Tolerance.Value = "High", "Blue",
Fields!Tolerance.Value = "Very High", "Green")

UNIVERSAL ADB DRIVER

I have thesame issue before but i solved it easily by just following this steps:

*connect your android phone in a debugging mode (to enable debugging mode goto settings scroll down About Phone scroll down tap seven times Build Number and it will automatically enable developer option turn on developer options and check USB debugging)

download Universal ADB Driver Installer

*choose Adb Driver Installer (Universal)

*install it *it will automatically detect your android device(any kind of brand) *chose the device and install

If the HTML is not XML you can't do it with etree. But even then, you don't have to use an external library for parsing a HTML table. In python 3 you can reach your goal with HTMLParser from html.parser. I've the code of the simple derived HTMLParser class here in a github repo.

You can use that class (here named HTMLTableParser) the following way:

import urllib.request
from html_table_parser import HTMLTableParser

target = 'http://www.twitter.com'

# get website content
req = urllib.request.Request(url=target)
f = urllib.request.urlopen(req)
xhtml = f.read().decode('utf-8')

# instantiate the parser and feed it
p = HTMLTableParser()
p.feed(xhtml)
print(p.tables)

The output of this is a list of 2D-lists representing tables. It looks maybe like this:

[[['   ', ' Anmelden ']],
 [['Land', 'Code', 'Für Kunden von'],
  ['Vereinigte Staaten', '40404', '(beliebig)'],
  ['Kanada', '21212', '(beliebig)'],
  ...
  ['3424486444', 'Vodafone'],
  ['  Zeige SMS-Kurzwahlen für andere Länder ']]]

You're looking for delete:

You should use getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); and getWindow().clearFlags(android.view.WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

The feature is called "code templates" in Eclipse. You can add templates with:

Window->Preferences->Java->Editor->Templates.

Two good articles:

• Don't write the code, generate it
• Custom Templates

Also, this SO question:

• Useful Eclipse Java Code Templates

System.out.println() is already mapped to sysout, so you may save time by learning a few of the existing templates first.

Class.getSimpleName()

Returns the simple name of the underlying class as given in the source code. Returns an empty string if the underlying class is anonymous.

The simple name of an array is the simple name of the component type with "[]" appended. In particular the simple name of an array whose component type is anonymous is "[]".

It is actually stripping the package information from the name, but this is hidden from you.

Look at ?par for the various graphics parameters.

In general cex controls size, col controls colour. If you want to control the colour of a label, the par is col.lab, the colour of the axis annotations col.axis, the colour of the main text, col.main etc. The names are quite intuitive, once you know where to begin.

For example

x <- 1:10
y <- 1:10

plot(x , y,xlab="x axis", ylab="y axis",  pch=19, col.axis = 'blue', col.lab = 'red', cex.axis = 1.5, cex.lab = 2)

If you need to change the colour / style of the surrounding box and axis lines, then look at ?axis or ?box, and you will find that you will be using the same parameter names within calls to box and axis.

You have a lot of control to make things however you wish.

eg

plot(x , y,xlab="x axis", ylab="y axis",  pch=19,  cex.lab = 2, axes = F,col.lab = 'red')
box(col = 'lightblue')
axis(1, col = 'blue', col.axis = 'purple', col.ticks = 'darkred', cex.axis = 1.5, font = 2, family = 'serif')
axis(2, col = 'maroon', col.axis = 'pink', col.ticks = 'limegreen', cex.axis = 0.9, font =3, family = 'mono')

Which is seriously ugly, but shows part of what you can control

You'll want to use a number of layout managers to help you achieve the basic results you want.

Check out A Visual Guide to Layout Managers for a comparision.

You could use a GridBagLayout but that's one of the most complex (and powerful) layout managers available in the JDK.

You could use a series of compound layout managers instead.

I'd place the graphics component and text area on a single JPanel, using a BorderLayout, with the graphics component in the CENTER and the text area in the SOUTH position.

I'd place the text field and button on a separate JPanel using a GridBagLayout (because it's the simplest I can think of to achieve the over result you want)

I'd place these two panels onto a third, master, panel, using a BorderLayout, with the first panel in the CENTER and the second at the SOUTH position.

But that's me

Update: The method mentioned in the original answer is deprecated, we should use the new way instead:

>>> import numpy as np
>>> x = [1,1,1,2,2,2,5,25,1,1]
>>> np.array(np.unique(x, return_counts=True)).T
    array([[ 1,  5],
           [ 2,  3],
           [ 5,  1],
           [25,  1]])

Original answer:

you can use scipy.stats.itemfreq

>>> from scipy.stats import itemfreq
>>> x = [1,1,1,2,2,2,5,25,1,1]
>>> itemfreq(x)
/usr/local/bin/python:1: DeprecationWarning: `itemfreq` is deprecated! `itemfreq` is deprecated and will be removed in a future version. Use instead `np.unique(..., return_counts=True)`
array([[  1.,   5.],
       [  2.,   3.],
       [  5.,   1.],
       [ 25.,   1.]])

From the post of https://github.com/CocoaPods/cocoapods-integration-specs/pull/24/files, that mean swift.dylib need sign but failed. I failed even create a new swift project with cocoapod support.

In my case, I wanted hours and minutes:

var duration = moment.duration(end.diff(startTime));
var hours = duration.hours(); //hours instead of asHours
var minutes = duration.minutes(); //minutes instead of asMinutes

For more info refer to the official docs.

Ok, if it doesn't matter which value in the non-duplicated column you select, this should be pretty easy:

dat <- data.frame(id=c(1,1,3),id2=c(1,1,4),somevalue=c("x","y","z"))
> dat[!duplicated(dat[,c('id','id2')]),]
  id id2 somevalue
1  1   1         x
3  3   4         z

Inside the duplicated call, I'm simply passing only those columns from dat that I don't want duplicates of. This code will automatically always select the first of any ambiguous values. (In this case, x.)

Local variables are automatically freed when the function ends, you don't need to free them by yourself. You only free dynamically allocated memory (e.g using malloc) as it's allocated on the heap:

char *arr = malloc(3 * sizeof(char));
strcpy(arr, "bo");
// ...
free(arr);

After struggling a lot, I finally found a solution, here we go -

Download the file jtds-1.3.1.jar and ntlmauth.dll and save it in Program File -> Java -> JDK -> jre -> bin.

Then use the following code -

String pPSSDBDriverName = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
Class.forName(pPSSDBDriverName);
DriverManager.registerDriver(new com.microsoft.sqlserver.jdbc.SQLServerDriver());
conn = DriverManager.getConnection("jdbc:jtds:sqlserver://<ur_server:port>;UseNTLMv2=true;Domain=AD;Trusted_Connection=yes");
stmt = conn.createStatement();
String sql = " DELETE FROM <data> where <condition>;
stmt.executeUpdate(sql);

Add these two file in your app.module.ts

import { FileTransfer } from '@ionic-native/file-transfer';
import { File } from '@ionic-native/file';

after that declare these to in provider..

providers: [
    Api,
    Items,
    User,
    Camera,
    File,
    FileTransfer];

This is work for me.

ShowMessage('Hello'+Chr(10)+'World');

Use the following code to get Name and Value of a dynamic object's property.

dynamic d = new { Property1= "Value1", Property2= "Value2"};

var properties = d.GetType().GetProperties();
foreach (var property in properties)
{
    var PropertyName=property.Name; 
//You get "Property1" as a result

  var PropetyValue=d.GetType().GetProperty(property.Name).GetValue(d, null); 
//You get "Value1" as a result

// you can use the PropertyName and Value here
 }

Check out the opensource Forge project. It provides a JavaScript TLS implementation, along with some Flash to handle the actual cross-domain requests:

http://github.com/digitalbazaar/forge/blob/master/README

In short, Forge will enable you to make XmlHttpRequests from a web page loaded over http to an https site. You will need to provide a Flash cross-domain policy file via your server to enable the cross-domain requests. Check out the blog posts at the end of the README to get a more in-depth explanation for how it works.

However, I should mention that Forge is better suited for requests between two different https-domains. The reason is that there's a potential MiTM attack. If you load the JavaScript and Flash from a non-secure site it could be compromised. The most secure use is to load it from a secure site and then use it to access other sites (secure or otherwise).

You can do using a simple notepad and save as FILENAME.json

That's all.

Using java 8 Stream API could simplify your job.

public static boolean inArray(int[] array, int check) {
    return Stream.of(array).anyMatch(i -> i == check);
}

It's just you have the overhead of creating a new Stream from Array, but this gives exposure to use other Stream API. In your case you may not want to create new method for one-line operation, unless you wish to use this as utility. Hope this helps!

You can pass it as Action<string> - which means it is a method with a single parameter of type string that doesn't return anything (void) :

public void DoRequest(string request, Action<string> callback)
{
    // do stuff....
    callback("asdf");
}

Using text/csv is the most appropriate type.

You should also consider adding a Content-Disposition header to the response. Often a text/csv will be loaded by a Internet Explorer directly into a hosted instance of Excel. This may or may not be a desirable result.

Response.AddHeader("Content-Disposition", "attachment;filename=myfilename.csv");

The above will cause a file "Save as" dialog to appear which may be what you intend.

I'd advise against using shorttags, see Are PHP short tags acceptable to use? for more information on why.

Personally I don't mind mixing HTML and PHP like so

<a href="<?php echo $link;?>">link description</a>

As long as I have a code-editor with good syntax highlighting, I think this is pretty readable. If you start echoing HTML with PHP then you lose all the advantages of syntax highlighting your HTML. Another disadvantage of echoing HTML is the stuff with the quotes, the following is a lot less readable IMHO.

echo '<a href="'.$link.'">link description</a>';

The biggest advantage for me with simple echoing and simple looping in PHP and doing the rest in HTML is that indentation is consistent, which in the end improves readability/scannability.

uniq has the option you need:

   -u, --unique
          only print unique lines

$ cat file.txt
1
1
2
3
5
5
7
7
$ uniq -u file.txt
2
3

We are running Linux, a mostly POSIX-compliant OS. POSIX standards it should be: Utility Argument Syntax.

• An option is a hyphen followed by a single alphanumeric character, like this: -o.
• An option may require an argument (which must appear immediately after the option); for example, -o argument or -oargument.
• Options that do not require arguments can be grouped after a hyphen, so, for example, -lst is equivalent to -t -l -s.
• Options can appear in any order; thus -lst is equivalent to -tls.
• Options can appear multiple times.
• Options precede other nonoption arguments: -lst nonoption.
• The -- argument terminates options.
• The - option is typically used to represent one of the standard input streams.

You can easily achieve what you want using the appendix package. Here's a sample file that shows you how. The key is the titletoc option when calling the package. It takes whatever value you've defined in \appendixname and the default value is Appendix.

\documentclass{report}
\usepackage[titletoc]{appendix}
\begin{document}
\tableofcontents

\chapter{Lorem ipsum}
\section{Dolor sit amet}
\begin{appendices}
  \chapter{Consectetur adipiscing elit}
  \chapter{Mauris euismod}
\end{appendices}
\end{document}

The output looks like

As you have it, the argument w is expecting a value after -w on the command line. If you are just looking to flip a switch by setting a variable True or False, have a look here (specifically store_true and store_false)

import argparse

parser = argparse.ArgumentParser()
parser.add_argument('-w', action='store_true')

where action='store_true' implies default=False.

Conversely, you could haveaction='store_false', which implies default=True.

I'm surprised no one has suggested this variation:

SELECT SUM(c)
FROM (
  SELECT COUNT(*) AS c FROM foo1 WHERE ID = '00123244552000258'
  UNION ALL
  SELECT COUNT(*) FROM foo2 WHERE ID = '00123244552000258'
  UNION ALL
  SELECT COUNT(*) FROM foo3 WHERE ID = '00123244552000258'
);

re.findall finds all the occurrence of the regex in a string and return in a list. Here, you are using a list of strings, you need this to use re.findall

Note - If the regex fails, an empty list is returned.

import re, sys

f = open('picklee', 'r')
lines = f.readlines()  
regex = re.compile(r'[A-Z]+')
for line in lines:
     print (re.findall(regex, line))

I am using Windows 8 and the above solutions did not work out for me. I downgraded Postgres from 9.4 to 9.3. Man,it worked :)

How to work-it in Tomcat 7

I wanted to support a self signed certificate in a Tomcat App but the following snippet failed to work

import java.io.DataOutputStream;
import java.net.HttpURLConnection;
import java.net.URL;

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

        URL url = new URL("https:// ... .com");
        HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();

        httpURLConnection.setRequestMethod("POST");
        httpURLConnection.setRequestProperty("Accept-Language", "en-US,en;q=0.5");
        httpURLConnection.setDoOutput(true);
        DataOutputStream wr = new DataOutputStream(httpURLConnection.getOutputStream());

        String serializedMessage = "{}";
        wr.writeBytes(serializedMessage);
        wr.flush();
        wr.close();

        int responseCode = httpURLConnection.getResponseCode();
        System.out.println(responseCode);
    }
}

this is what solved my issue:

1) Download the .crt file

echo -n | openssl s_client -connect <your domain>:443 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > ~/<your domain>.crt

• replace <your domain> with your domain (e.g. jossef.com)

2) Apply the .crt file in Java's cacerts certificate store

keytool -import -v -trustcacerts -alias <your domain> -file ~/<your domain>.crt -keystore <JAVA HOME>/jre/lib/security/cacerts -keypass changeit -storepass changeit

• replace <your domain> with your domain (e.g. jossef.com)
• replace <JAVA HOME> with your java home directory

3) Hack it

Even though iv'e installed my certificate in Java's default certificate stores, Tomcat ignores that (seems like it's not configured to use Java's default certificate stores).

To hack this, add the following somewhere in your code:

String certificatesTrustStorePath = "<JAVA HOME>/jre/lib/security/cacerts";
System.setProperty("javax.net.ssl.trustStore", certificatesTrustStorePath);

// ...

I installed the Role plugin under Jenkins-3.5, but it does not show the "Manage Roles" option under "Manage Jenkins", and when one follows the security install page from the wiki, all users are locked out instantly. I had to manually shutdown Jenkins on the server, restore the correct configuration settings (/me is happy to do proper backups) and restart Jenkins.

I didn't have high hopes, as that plugin was last updated in 2011

Exactly what you need:) You can choose callback version or Promise version. Note that promises will work in IE only with Promise polyfill lib.You can put this code once on a page, and this function will appear in all your files.

The loadend event is fired when progress has stopped on the loading of a resource (e.g. after "error", "abort", or "load" have been dispatched)

<input type="file" id="asd" multiple/>

Well, I wrote a piece of code inspired by many of the above answers that should easily work in most scenarios where the server sends a file with a content disposition header, without any third-party installations, except rxjs and angular.

First, how to call the code from your component file

this.httpclient.get(
   `${myBackend}`,
   {
      observe: 'response',
      responseType: 'blob'
   }
).pipe(first())
.subscribe(response => SaveFileResponse(response, 'Custom File Name.extension'));

As you can see, it's basically pretty much the average backend call from angular, with two changes

1. I am observing the response instead of the body
2. I am being explicit about the response being a blob

Once the file is fetched from the server, I am in principle, delegating the entire task of saving the file to the helper function, which I keep in a separate file, and import into whichever component I need to

export const SaveFileResponse = 
(response: HttpResponse<Blob>, 
 filename: string = null) => 
{
    //null-checks, just because :P
    if (response == null || response.body == null)
        return;

    let serverProvidesName: boolean = true;
    if (filename != null)
        serverProvidesName = false;

    //assuming the header is something like
    //content-disposition: attachment; filename=TestDownload.xlsx; filename*=UTF-8''TestDownload.xlsx
    if (serverProvidesName)
        try {
            let f: string = response.headers.get('content-disposition').split(';')[1];
            if (f.includes('filename='))
                filename = f.substring(10);
        }
        catch { }
    SaveFile(response.body, filename);
}

//Create an anchor element, attach file to it, and
//programmatically click it. 
export const SaveFile = (blobfile: Blob, filename: string = null) => {
    const a = document.createElement('a');
    a.href = window.URL.createObjectURL(blobfile);
    a.download = filename;
    a.click();
}

There, no more cryptic GUID filenames! We can use whatever name the server provides, without having to specify it explicitly in the client, or, overwrite the filename provided by the server (as in this example). Also, one can easily, if need be, change the algorithm of extracting the filename from the content-disposition to suit their needs, and everything else will stay unaffected - in case of an error during such extraction, it will just pass 'null' as the filename.

As another answer already pointed out, IE needs some special treatment, as always. But with chromium edge coming in a few months, I wouldn't worry about that while building new apps (hopefully). There is also the matter of revoking the URL, but I'm kinda not-so-sure about that, so if someone could help out with that in the comments, that would be awesome.

Below is code snippet you can use to delete the bucket,

In my case, I stopped my docker hive container and run it again and finally, it worked. Hope it will be useful for someone.

Note: This might be caused because there might be an instance running in the background so stopping the container will stop all background instances.

Now that you have provided your HTML sample, we're able to see that your XPath is slightly wrong. While it's valid XPath, it's logically wrong.

You've got:

//*[contains(@id, 'ctl00_btnAircraftMapCell')]//*[contains(@title, 'Select Seat')]

Which translates into:

Get me all the elements that have an ID that contains ctl00_btnAircraftMapCell. Out of these elements, get any child elements that have a title that contains Select Seat.

What you actually want is:

//a[contains(@id, 'ctl00_btnAircraftMapCell') and contains(@title, 'Select Seat')]

Which translates into:

Get me all the anchor elements that have both: an id that contains ctl00_btnAircraftMapCell and a title that contains Select Seat.

I hate adding function-named classes to my code, so I put this together instead. If I were to stop using smooth scrolling, I'd feel behooved to go through my code, and delete all the class="scroll" stuff. Using this technique, I can comment out 5 lines of JS, and the entire site updates. :)

<a href="/about">Smooth</a><!-- will never trigger the function -->
<a href="#contact">Smooth</a><!-- but he will -->
...
...
<div id="contact">...</div>


<script src="jquery.js" type="text/javascript"></script>
<script type="text/javascript">
    // Smooth scrolling to element IDs
    $('a[href^=#]:not([href=#])').on('click', function () {
        var element = $($(this).attr('href'));
        $('html,body').animate({ scrollTop: element.offset().top },'normal', 'swing');
        return false;
    });
</script>

Requirements:
1. <a> elements must have an href attribute that begin with # and be more than just #
2. An element on the page with a matching id attribute

What it does:
1. The function uses the href value to create the anchorID object
   - In the example, it's $('#contact'), /about starts with /
2. HTML, and BODY are animated to the top offset of anchorID
   - speed = 'normal' ('fast','slow', milliseconds, )
   - easing = 'swing' ('linear',etc ... google easing)
3. return false -- it prevents the browser from showing the hash in the URL
   - the script works without it, but it's not as "smooth".

Using HTML 5,Just make the input email like :

<input type="email"/>

When the user hovers over the input box, they will a tooltip instructing them to enter a valid email. However, Bootstrap forms have a much better Tooltip message to tell the user to enter an email address and it pops up the moment the value entered does not match a valid email.

Edit: added information about ngMessages (>= 1.3.X) below.

Standard form validation messages (1.0.X and above)

Since this is one of the top results if you Google "Angular Form Validation", currently, I want to add another answer to this for anyone coming in from there.

There's a method in FormController.$setValidity but that doesn't look like a public API so I rather not use it.

It's "public", no worries. Use it. That's what it's for. If it weren't meant to be used, the Angular devs would have privatized it in a closure.

To do custom validation, if you don't want to use Angular-UI as the other answer suggested, you can simply roll your own validation directive.

app.directive('blacklist', function (){ 
   return {
      require: 'ngModel',
      link: function(scope, elem, attr, ngModel) {
          var blacklist = attr.blacklist.split(',');

          //For DOM -> model validation
          ngModel.$parsers.unshift(function(value) {
             var valid = blacklist.indexOf(value) === -1;
             ngModel.$setValidity('blacklist', valid);
             return valid ? value : undefined;
          });

          //For model -> DOM validation
          ngModel.$formatters.unshift(function(value) {
             ngModel.$setValidity('blacklist', blacklist.indexOf(value) === -1);
             return value;
          });
      }
   };
});

And here's some example usage:

<form name="myForm" ng-submit="doSomething()">
   <input type="text" name="fruitName" ng-model="data.fruitName" blacklist="coconuts,bananas,pears" required/>
   <span ng-show="myForm.fruitName.$error.blacklist">
      The phrase "{{data.fruitName}}" is blacklisted</span>
   <span ng-show="myForm.fruitName.$error.required">required</span>
   <button type="submit" ng-disabled="myForm.$invalid">Submit</button>
</form>

Note: in 1.2.X it's probably preferrable to substitute ng-if for ng-show above

Here is an obligatory plunker link

Also, I've written a few blog entries about just this subject that goes into a little more detail:

Angular Form Validation

Custom Validation Directives

Edit: using ngMessages in 1.3.X

You can now use the ngMessages module instead of ngShow to show your error messages. It will actually work with anything, it doesn't have to be an error message, but here's the basics:

1. Include <script src="angular-messages.js"></script>

2. Reference ngMessages in your module declaration:

   var app = angular.module('myApp', ['ngMessages']);
   

3. Add the appropriate markup:

   <form name="personForm">
     <input type="email" name="email" ng-model="person.email" required/>
   
     <div ng-messages="personForm.email.$error">
       <div ng-message="required">required</div>
       <div ng-message="email">invalid email</div>
     </div>
   </form>
   

In the above markup, ng-message="personForm.email.$error" basically specifies a context for the ng-message child directives. Then ng-message="required" and ng-message="email" specify properties on that context to watch. Most importantly, they also specify an order to check them in. The first one it finds in the list that is "truthy" wins, and it will show that message and none of the others.

And a plunker for the ngMessages example

I stumbled across this question and developed a more concise version of Elliot BOnneville's answer:

var conceptName = $('#aioConceptName :selected').text();

or generically:

$('#id :pseudoclass')

This saves you an extra jQuery call, selects everything in one shot, and is more clear (my opinion).

In visual studio code i found that simple regex as ^ worked.

If you installed the command line tools separately, delete them using:

sudo rm -rf /Library/Developer/CommandLineTools

Try operator instanceof.

By using this on bootstrap 3:

#carousel-example-generic{
    margin:auto;
}

The best way to achieve what you want is to create your own wpf based control , or use a one that was made by other people
why ? because there will be a noticeable performance impact when using the winforms dialog in a wpf application (for some reason)
i recommend this project
https://opendialog.codeplex.com/
or Nuget :

PM> Install-Package OpenDialog

it's very MVVM friendly and it isn't wraping the winforms dialog

1. Click on settings in top tool bar;

2. Click on debugger;

3. In tree, highlight "gdb/cdb debugger" by clicking it

4. Click "create configuration"

5. Add "gdb.exe" (no quotes) as a configuration

6. Delete default configuration

7. Click on gdb.exe that you created in the tree (it should be the only one) and a dialogue will appear to the right for "executable path" with a button to the right.

8. Click on that button and it will bring up the file that codeblocks is installed in. Just keep clicking until you create the path to the gdb.exe (it sort of finds itself).

You didn't use FROM expression for a table

SELECT DISTINCT Description, Date as treatmentDate
**FROM <A TABLE>**
WHERE doothey.Patient P, doothey.Account A, doothey.AccountLine AL, doothey.Item.I
AND P.PatientID = A.PatientID
AND A.AccountNo = AL.AccountNo
AND AL.ItemNo = I.ItemNo
AND (p.FamilyName = 'Stange' AND p.GivenName = 'Jessie');

I think you should give the data types of the column as NUMERIC or DOUBLE or FLOAT or REAL

Read http://sqlite.org/datatype3.html to more info.

From help(print):

Help on built-in function print in module builtins:

print(...)
    print(value, ..., sep=' ', end='\n', file=sys.stdout)

    Prints the values to a stream, or to sys.stdout by default.
    Optional keyword arguments:
    file: a file-like object (stream); defaults to the current sys.stdout.
    sep:  string inserted between values, default a space.
    end:  string appended after the last value, default a newline.

You can use the end keyword:

>>> for i in range(1, 11):
...     print(i, end='')
... 
12345678910>>> 

Note that you'll have to print() the final newline yourself. BTW, you won't get "12345678910" in Python 2 with the trailing comma, you'll get 1 2 3 4 5 6 7 8 9 10 instead.

I found one way to access the shared folder without giving the username and password.

We need to change the share folder protect settings in the machine where the folder has been shared.

Go to Control Panel > Network and sharing center > Change advanced sharing settings > Enable Turn Off password protect sharing option.

By doing the above settings we can access the shared folder without any username/password.

It will be fixed 64 chars, so use char(64)

If your application often uses http protocol then REST is best because of its light weight, and knowing that your application uses only http protocol choosing SOAP is not so good because it heavy,Better to make decision on web service selection based on the protocols we use in our applications.

The error usually means that the port you are trying to open is being already used by another application. Try using netstat to see which ports are open and then use an available port.

Also check if you are binding to the right ip address (I am assuming it would be localhost)

The verbose option is handy, but if you want to see everything that curl does (including the HTTP body that is transmitted, and not just the headers), I suggest using one of the below options:

• --trace-ascii - # stdout
• --trace-ascii output_file.txt # file

This happens sometimes when I'm trying to open my old projects, what helps me is to change projects target framework. Go to Project -> projectname Properties... and change the Target framework to the one that you have installed.

I have fix for this issue,

example if you are assigning some values to DataFrame

[*] symbol has shown this because of the script running

to see the outout of the script have to mention df like this, output

I have the current latest version of MySQL: 8.0.20

So my table name is visit, my column name is curdate.

alter table visit modify curdate date not null default (current_date);

This writes the default date value with no timestamp.

There are two things

1- If its already a Eclipse Project, then simply go to File->Import->General->Existing Project into Workplace

2- Otherwise define project type e.g. Java, Web etc Create a new project of type you define into your workplace. Copy Paste source , lib and other necessary files. refresh, compile and run project in eclipse.

The answers from @unbeli and @Niklas are good, but @unbeli's answer does not work for all hex strings and it is desirable to do the decoding without importing an extra library (codecs). The following should work (but will not be very efficient for large strings):

>>> result = bytes.fromhex((lambda s: ("%s%s00" * (len(s)//2)) % tuple(s))('4a82fdfeff00')).decode('utf-16-le')
>>> result == '\x4a\x82\xfd\xfe\xff\x00'
True

Basically, it works around having invalid utf-8 bytes by padding with zeros and decoding as utf-16.

In my case it was much easier. I turned off the native windows firewall. Then re-loaded comp launched xampp and started apache again. Then turned the firewall on back.

for /f "tokens=* delims= " %%f in (myfile) do

This reads a file line-by-line, removing leading spaces (thanks, jeb).

set line=%%f

sets then the line variable to the line just read and

call :procesToken

calls a subroutine that does something with the line

:processToken

is the start of the subroutine mentioned above.

for /f "tokens=1* delims=/" %%a in ("%line%") do

will then split the line at /, but stopping tokenization after the first token.

echo Got one token: %%a

will output that first token and

set line=%%b

will set the line variable to the rest of the line.

if not "%line%" == "" goto :processToken

And if line isn't yet empty (i.e. all tokens processed), it returns to the start, continuing with the rest of the line.

It isn't pretty, but it works. If you have access apache commons i would suggest that use that

if (val.length() < 8) {
  for (int i = 0; i < val - 8; i++) {
    val = "0" + val;
  }
}

You can find the target element in event.target:

$(document).click(function(event) {
    console.log($(event.target).text());
});

Most of the roles you see were defined as part of ARIA 1.0, and then later incorporated into HTML via supporting specs like HTML-AAM. Some of the new HTML5 elements (dialog, main, etc.) are even based on the original ARIA roles.

http://www.w3.org/TR/wai-aria/

There are a few primary reasons to use roles in addition to your native semantic element.

Reason #1. Overriding the role where no host language element is appropriate or, for various reasons, a less semantically appropriate element was used.

In this example, a link was used, even though the resulting functionality is more button-like than a navigation link.

<a href="#" role="button" aria-label="Delete item 1">Delete</a>
<!-- Note: href="#" is just a shorthand here, not a recommended technique. Use progressive enhancement when possible. -->

Screen readers users will hear this as a button (as opposed to a link), and you can use a CSS attribute selector to avoid class-itis and div-itis.

[role="button"] {
  /* style these as buttons w/o relying on a .button class */
}

[Update 7 years later: removed the * selector to make some commenters happy, since the old browser quirk that required universal selector on attribute selectors is unnecessary in 2020.]

Reason #2. Backing up a native element's role, to support browsers that implemented the ARIA role but haven't yet implemented the native element's role.

For example, the "main" role has been supported in browsers for many years, but it's a relatively recent addition to HTML5, so many browsers don't yet support the semantic for <main>.

<main role="main">…</main>

This is technically redundant, but helps some users and doesn't harm any. In a few years, this technique will likely become unnecessary for main.

Reason #3. Update 7 years later (2020): As at least one commenter pointed out, this is now very useful for custom elements, and some spec work is underway to define the default accessibility role of a web component. Even if/once that API is standardized, there may be need to override the default role of a component.

Note/Reply

You also wrote:

I see some people make up their own. Is that allowed or a correct use of the role attribute?

That's an allowed use of the attribute unless a real role is not included. Browsers will apply the first recognized role in the token list.

<span role="foo link note bar">...</a>

Out of the list, only link and note are valid roles, and so the link role will be applied in the platform accessibility API because it comes first. If you use custom roles, make sure they don't conflict with any defined role in ARIA or the host language you're using (HTML, SVG, MathML, etc.)

Was facing the same issue and unfortunately nothing here was working. Finally, I came across this link: https://blogs.msdn.microsoft.com/jjameson/2009/11/18/the-copy-local-bug-in-visual-studio/

Turns out the solution is sort of dumb: set copy-local for the microsoft.web.infrastructure dll to False, then set it back to True.

By the way, I think what is happening is that there are two versions of the microsoft.web.infrastructure dll, one that is pre-installed in the GAC, and another one that is now a nuget package. I think one is masking the other, hence causing issues. In my particular case, on my build server, I need it to be copied over to a folder (this folder is then zipped and sent off to deployment). I guess the system had a copy locally and just thought "nah, it'll be fine"

2016 update

With the latest release of Google Play Services, v7.8, you have access to the new Mobile Vision API. That's probably the most convenient way to implement barcode scanning now, and it also works offline.

From the Android Barcode API:

The Barcode API detects barcodes in real-time, on device, in any orientation. It can also detect multiple barcodes at once.

It reads the following barcode formats:

• 1D barcodes: EAN-13, EAN-8, UPC-A, UPC-E, Code-39, Code-93, Code-128, ITF, Codabar
• 2D barcodes: QR Code, Data Matrix, PDF-417, AZTEC

It automatically parses QR Codes, Data Matrix, PDF-417, and Aztec values, for the following supported formats:

• URL
• Contact information (VCARD, etc.)
• Calendar event
• Email
• Phone
• SMS
• ISBN
• WiFi
• Geo-location (latitude and longitude)
• AAMVA driver license/ID

You can simply edit your configuration file in a text editor.

In the ~/.gitconfig you need to put in something like the following:

[user]
        name  = Uzumaki Naruto
        email = [email protected]

[github]
        user = myname
        token = ff44ff8da195fee471eed6543b53f1ff

In the oldrep/.git/config file (in the configuration file of your repository):

[remote "github"]
        url = [email protected]:myname/oldrep.git
        push  = +refs/heads/*:refs/heads/*
        push  = +refs/tags/*:refs/tags/*

If there is a remote section in your repository's configuration file, and the URL matches, you need only to add push configuration. If you use a public URL for fetching, you can put in the URL for pushing as 'pushurl' (warning: this requires the just-released Git version 1.6.4).

CAST both fields to datatype DATE and you can use a minus:

(CAST(MAX(joindate) AS date) - CAST(MIN(joindate) AS date)) as DateDifference

Test case:

SELECT  (CAST(MAX(joindate) AS date) - CAST(MIN(joindate) AS date)) as DateDifference
FROM 
    generate_series('2014-01-01'::timestamp, '2014-02-01'::timestamp, interval '1 hour') g(joindate);

Result: 31

Or create a function datediff():

CREATE OR REPLACE FUNCTION datediff(timestamp, timestamp) 
RETURNS int 
LANGUAGE sql 
AS
$$
    SELECT CAST($1 AS date) - CAST($2 AS date) as DateDifference
$$;

You can split date month year from current date as follows:

DateTime todaysDate = DateTime.Now.Date;

Day:

int day = todaysDate.Day;

Month:

int month = todaysDate.Month;

Year:

int year = todaysDate.Year;

There are a few options available for you depending on the library in question, how it's written, and what level of accuracy you're looking for. Let's review the options, in roughly descending order of desirability.

Maybe It Exists Already

Always check DefinitelyTyped (https://github.com/DefinitelyTyped/DefinitelyTyped) first. This is a community repo full of literally thousands of .d.ts files and it's very likely the thing you're using is already there. You should also check TypeSearch (https://microsoft.github.io/TypeSearch/) which is a search engine for NPM-published .d.ts files; this will have slightly more definitions than DefinitelyTyped. A few modules are also shipping their own definitions as part of their NPM distribution, so also see if that's the case before trying to write your own.

Maybe You Don't Need One

TypeScript now supports the --allowJs flag and will make more JS-based inferences in .js files. You can try including the .js file in your compilation along with the --allowJs setting to see if this gives you good enough type information. TypeScript will recognize things like ES5-style classes and JSDoc comments in these files, but may get tripped up if the library initializes itself in a weird way.

Get Started With --allowJs

If --allowJs gave you decent results and you want to write a better definition file yourself, you can combine --allowJs with --declaration to see TypeScript's "best guess" at the types of the library. This will give you a decent starting point, and may be as good as a hand-authored file if the JSDoc comments are well-written and the compiler was able to find them.

Get Started with dts-gen

If --allowJs didn't work, you might want to use dts-gen (https://github.com/Microsoft/dts-gen) to get a starting point. This tool uses the runtime shape of the object to accurately enumerate all available properties. On the plus side this tends to be very accurate, but the tool does not yet support scraping the JSDoc comments to populate additional types. You run this like so:

npm install -g dts-gen
dts-gen -m <your-module>

This will generate your-module.d.ts in the current folder.

Hit the Snooze Button

If you just want to do it all later and go without types for a while, in TypeScript 2.0 you can now write

declare module "foo";

which will let you import the "foo" module with type any. If you have a global you want to deal with later, just write

declare const foo: any;

which will give you a foo variable.

Here is a tidyverse option that might work depending on the data, and some caveats on its usage:

library(tidyverse)

starting_df %>% 
  rownames_to_column() %>% 
  gather(variable, value, -rowname) %>% 
  spread(rowname, value)

rownames_to_column() is necessary if the original dataframe has meaningful row names, otherwise the new column names in the new transposed dataframe will be integers corresponding to the orignal row number. If there are no meaningful row names you can skip rownames_to_column() and replace rowname with the name of the first column in the dataframe, assuming those values are unique and meaningful. Using the tidyr::smiths sample data would be:

smiths %>% 
    gather(variable, value, -subject) %>% 
    spread(subject, value)

Using the example starting_df with the tidyverse approach will throw a warning message about dropping attributes. This is related to converting columns with different attribute types into a single character column. The smiths data will not give that warning because all columns except for subject are doubles.

The earlier answer using as.data.frame(t()) will convert everything to a factor if there are mixed column types unless stringsAsFactors = FALSE is added, whereas the tidyverse option converts everything to a character by default if there are mixed column types.

In Git 2.x:

• If you are located directly at the working directory, then git add -A and git add . work without the difference.

• If you are in any subdirectory of the working directory, git add -A will add all files from the entire working directory, and git add . will add files from your current directory.

And that's all.

MSDN has provided easy way to debug the stored procedure. Please check this link-
How to: Debug Stored Procedures

Try this:

CREATE TABLE `test_table` (
`id` INT( 10 ) NOT NULL,
`created_at` TIMESTAMP NOT NULL DEFAULT 0,
`updated_at` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
) ENGINE = INNODB;

Use this:

SELECT * 
FROM tablename 
ORDER BY priority desc, FIELD(name, "core")

The task can be solved using the following piece of code, [0:28] being interval where the name is being held, while [29:34] contains the actual pid.

import os

program_pid = 0
program_name = "notepad.exe"

task_manager_lines = os.popen("tasklist").readlines()
for line in task_manager_lines:
    try:
        if str(line[0:28]) == program_name + (28 - len(program_name) * ' ': #so it includes the whitespaces
            program_pid = int(line[29:34])
            break
    except:
        pass

print(program_pid)

Use this ^[a-zA-Z0-9_]*$

See here for more info.

make sure that your path is pointing to .exe file in C:\Program Files\7-Zip (may in bin directory)

Just to add an additional function should you need it. You can include a variable in the named location, for example a date identifier

date <- yyyymmdd
save(city, file=paste0("c:\\myuser\\somelocation\\",date,"_RData.Data")

This was you can always keep a check of when it was run

Short version: it's marking that hash as attached to the current package namespace (so that that package provides its class implementation).

Checkboxes are a control type designed for one purpose: to ensure valid entry of Boolean values.

In Access, there are two types:

1. 2-state -- can be checked or unchecked, but not Null. Values are True (checked) or False (unchecked). In Access and VBA, the value of True is -1 and the value of False is 0. For portability with environments that use 1 for True, you can always test for False or Not False, since False is the value 0 for all environments I know of.

2. 3-state -- like the 2-state, but can be Null. Clicking it cycles through True/False/Null. This is for binding to an integer field that allows Nulls. It is of no use with a Boolean field, since it can never be Null.

Minor quibble with the answers:

There is almost never a need to use the .Value property of an Access control, as it's the default property. These two are equivalent:

  ?Me!MyCheckBox.Value
  ?Me!MyCheckBox

The only gotcha here is that it's important to be careful that you don't create implicit references when testing the value of a checkbox. Instead of this:

  If Me!MyCheckBox Then

...write one of these options:

  If (Me!MyCheckBox) Then  ' forces evaluation of the control

  If Me!MyCheckBox = True Then

  If (Me!MyCheckBox = True) Then

  If (Me!MyCheckBox = Not False) Then

Likewise, when writing subroutines or functions that get values from a Boolean control, always declare your Boolean parameters as ByVal unless you actually want to manipulate the control. In that case, your parameter's data type should be an Access control and not a Boolean value. Anything else runs the risk of implicit references.

Last of all, if you set the value of a checkbox in code, you can actually set it to any number, not just 0 and -1, but any number other than 0 is treated as True (because it's Not False). While you might use that kind of thing in an HTML form, it's not proper UI design for an Access app, as there's no way for the user to be able to see what value is actually be stored in the control, which defeats the purpose of choosing it for editing your data.

http://docs.python.org/howto/unicode.html#the-unicode-type

str = unicode(str, errors='replace')

or

str = unicode(str, errors='ignore')

Note: This will strip out (ignore) the characters in question returning the string without them.

For me this is ideal case since I'm using it as protection against non-ASCII input which is not allowed by my application.

Alternatively: Use the open method from the codecs module to read in the file:

import codecs
with codecs.open(file_name, 'r', encoding='utf-8',
                 errors='ignore') as fdata:

If you have a main activity with many fragments you put in, usually using the navigationDrawer. And you have an array of titles for yours fragments, when you press back, for them to change, put this in the main actity that hold the fragments

@Override
     public void onBackPressed() {

    int T=getSupportFragmentManager().getBackStackEntryCount();
    if(T==1) { finish();}

    if(T>1) {
        int tr = Integer.parseInt(getSupportFragmentManager().getBackStackEntryAt(T-2).getName());
        setTitle(navMenuTitles[tr]);  super.onBackPressed();
      }

}

This assumes that for each fragment you give it a tag, usually somewhere when you add the fragments to the list of navigationDrawer, according to the position pressed on the list. So that position is what i capture on the tag:

    fragmentManager.beginTransaction().
replace(R.id.frame_container, fragment).addToBackStack(position).commit();

Now, the navMenuTitles is something you load on the onCreate

 // load slide menu items
        navMenuTitles = getResources().getStringArray(R.array.nav_drawer_items);

The array xml is an array type string resource on strings.xml

 <!-- Nav Drawer Menu Items -->
    <string-array name="nav_drawer_items">
        <item>Title one</item>
        <item>Title Two</item>
    </string-array>

Incremental development means that different parts of a software project are continuously integrated into the whole, instead of a monolithic approach where all the different parts are assembled in one or a few milestones of the project.

Iterative means that once a first version of a component is complete it is tested, reviewed and the results are almost immediately transformed into a new version (iteration) of this component.

So as a first result: iterative development doesn't need to be incremental and vice versa, but these methods are a good fit.

Agile development aims to reduce massive planing overhead in software projects to allow fast reactions to change e.g. in customer wishes. Incremental and iterative development are almost always part of an agile development strategy. There are several approaches to Agile development (e.g. scrum).

If you are using the glyphicon as the first character of the string, you can use the html char (see https://glyphicons.bootstrapcheatsheets.com/) and then apply the font to the first character of the element:

    option::first-letter{
        font-family: Glyphicons Halflings;
    }

You can use constructor property:

'foo'.constructor == String // returns true
true.constructor == Boolean // returns true

For some unexplained reason this solution doesn't work for me (maybe some incompatibility of types), so I came up with a solution for myself:

HttpResponseMessage response = await client.GetAsync("api/yourcustomobjects");
if (response.IsSuccessStatusCode)
{
    var data = await response.Content.ReadAsStringAsync();
    var product = JsonConvert.DeserializeObject<Product>(data);
}

This way my content is parsed into a JSON string and then I convert it to my object.

How about this:

EXECUTE xp_regread @rootkey='HKEY_LOCAL_MACHINE',
                   @key='SOFTWARE\Microsoft\Microsoft SQL Server\Instance Names\SQl',
                   @value_name='MSSQLSERVER'

This will get the instance name as well. null means default instance:

SELECT SERVERPROPERTY ('InstanceName')

"...by a class and a div."

I assume when you say "div" you mean "id"? Try this:

$('#test2.test1').prop('checked', true);

No need to muck about with your [attributename=value] style selectors because id has its own format as does class, and they're easily combined although given that id is supposed to be unique it should be enough on its own unless your meaning is "select that element only if it currently has the specified class".

Or more generally to select an input where you want to specify a multiple attribute selector:

$('input:radio[class=test1][id=test2]').prop('checked', true);

That is, list each attribute with its own square brackets.

Note that unless you have a pretty old version of jQuery you should use .prop() rather than .attr() for this purpose.

Try remove_missing instead with vars = the_variable. It is very important that you set the vars argument, otherwise remove_missing will remove all rows that contain an NA in any column!! Setting na.rm = TRUE will suppress the warning message.

ggplot(data = remove_missing(MyData, na.rm = TRUE, vars = the_variable),aes(x= the_variable, fill=the_variable, na.rm = TRUE)) + 
       geom_bar(stat="bin") 

I had this error and it was caused by a typo in the connection string in App.config.

#!/bin/bash
ps axho comm| grep $1 > /dev/null
result=$?
echo "exit code: ${result}"
if [ "${result}" -eq "0" ] ; then
echo "`date`: $SERVICE service running, everything is fine"

Something like this

I ran into this having 2 Doctrine DBAL connections, one of those as non-transactional (for important logs), they are intended to run parallel not depending on each other.

CodeExecution(
    TransactionConnectionQuery()
    TransactionlessConnectionQuery()
)

My integration tests were wrapped into transactions for data rollback after very test.

beginTransaction()
CodeExecution(
    TransactionConnectionQuery()
    TransactionlessConnectionQuery() // CONFLICT
)
rollBack()

My solution was to disable the wrapping transaction in those tests and reset the db data in another way.

Client use convert File to ToBase64String, after use Xml to promulgate to Server call, this server use File.WriteAllBytes(path,Convert.FromBase64String(dataFile_Client_sent)).

Good lucky!

This option fixed my issue.

/* Example */_x000D_
var jsonObject = {"name": "John", "age": 30, "car": null};_x000D_
saveAsFile('out.json', JSON.stringify(jsonObject, null, 2));

The function is called like saveAsFile('out.json', jsonString);. It will create a ByteStream immediately recognized by the browser that will download the generated file directly using the File API URL.createObjectURL.

In the else, it is possible to see the same result obtained via the href element plus the Data API, but this has several limitations that the Blob API has not.

I did it in a easier way , setEditable and setFocusable false. but you should check this.

How to replicate android:editable="false" in code?

Try this

cd repo1

This will remove all the directories except the ones mentioned, preserving history only for these directories

git filter-branch --index-filter 'git rm --ignore-unmatch --cached -qr -- . && git reset -q $GIT_COMMIT -- dir1/ dir2/ dir3/ ' --prune-empty -- --all

Now you can add your new repo in your git remote and push it to that

git remote remove origin <old-repo>

git remote add origin <new-repo>

git push origin <current-branch>

add -f to overwrite

No matter what we tried we couldn't manage to get the timeout below 21 seconds when the server we were checking was down.

To work around this we combined a TcpClient check to see if the domain was alive followed by a separate check to see if the URL was active

public static bool IsUrlAlive(string aUrl, int aTimeoutSeconds)
{
    try
    {
        //check the domain first
        if (IsDomainAlive(new Uri(aUrl).Host, aTimeoutSeconds))
        {
            //only now check the url itself
            var request = System.Net.WebRequest.Create(aUrl);
            request.Method = "HEAD";
            request.Timeout = aTimeoutSeconds * 1000;
            var response = (HttpWebResponse)request.GetResponse();
            return response.StatusCode == HttpStatusCode.OK;
        }
    }
    catch
    {
    }
    return false;

}

private static bool IsDomainAlive(string aDomain, int aTimeoutSeconds)
{
    try
    {
        using (TcpClient client = new TcpClient())
        {
            var result = client.BeginConnect(aDomain, 80, null, null);

            var success = result.AsyncWaitHandle.WaitOne(TimeSpan.FromSeconds(aTimeoutSeconds));

            if (!success)
            {
                return false;
            }

            // we have connected
            client.EndConnect(result);
            return true;
        }
    }
    catch
    {

Pinal Dave has a nice article with some examples on how to add trailing 0s to SQL numbers.

One way is using the RIGHT function, which would make the statement something like the following:

SELECT RIGHT('00' + CAST(DATEPART(mm, @date) AS varchar(2)), 2)

I had a similar problem in reading a graph from a file. The processing included the computation of a 200 000x200 000 float matrix (one line at a time) that did not fit into memory. Trying to free the memory between computations using gc.collect() fixed the memory-related aspect of the problem but it resulted in performance issues: I don't know why but even though the amount of used memory remained constant, each new call to gc.collect() took some more time than the previous one. So quite quickly the garbage collecting took most of the computation time.

To fix both the memory and performance issues I switched to the use of a multithreading trick I read once somewhere (I'm sorry, I cannot find the related post anymore). Before I was reading each line of the file in a big for loop, processing it, and running gc.collect() every once and a while to free memory space. Now I call a function that reads and processes a chunk of the file in a new thread. Once the thread ends, the memory is automatically freed without the strange performance issue.

Practically it works like this:

from dask import delayed  # this module wraps the multithreading
def f(storage, index, chunk_size):  # the processing function
    # read the chunk of size chunk_size starting at index in the file
    # process it using data in storage if needed
    # append data needed for further computations  to storage 
    return storage

partial_result = delayed([])  # put into the delayed() the constructor for your data structure
# I personally use "delayed(nx.Graph())" since I am creating a networkx Graph
chunk_size = 100  # ideally you want this as big as possible while still enabling the computations to fit in memory
for index in range(0, len(file), chunk_size):
    # we indicates to dask that we will want to apply f to the parameters partial_result, index, chunk_size
    partial_result = delayed(f)(partial_result, index, chunk_size)

    # no computations are done yet !
    # dask will spawn a thread to run f(partial_result, index, chunk_size) once we call partial_result.compute()
    # passing the previous "partial_result" variable in the parameters assures a chunk will only be processed after the previous one is done
    # it also allows you to use the results of the processing of the previous chunks in the file if needed

# this launches all the computations
result = partial_result.compute()

# one thread is spawned for each "delayed" one at a time to compute its result
# dask then closes the tread, which solves the memory freeing issue
# the strange performance issue with gc.collect() is also avoided

I'm against using when others so I would use (returning an "boolean integer" due to SQL not suppporting booleans)

create or replace function is_number(param in varchar2) return integer
 is
   ret number;
 begin
    ret := to_number(param);
    return 1; --true
 exception
    when invalid_number then return 0;
 end;

In the SQL call you would use something like

select case when ( is_number(myTable.id)=1 and (myTable.id >'0') ) 
            then 'Is a number greater than 0' 
            else 'it is not a number or is not greater than 0' 
       end as valuetype  
  from table myTable

Your question is already answered here :

• Why do we use rt.jar file in java project ?

Basically, rt.jar contains all of the compiled class files for the base Java Runtime ("rt") Environment. Normally, javac should know the path to this file

Also, a good link on what happens if we try to include our class file in rt.jar.

It's possible that you already have the Lombok plugin, and still the generated methods are not recognised by Android Studio. In such case the plugin might be out of date, so the solution is to simply update it.

From Excel Macro Security - www.excelfunctions.net:

Macro Security in Excel 2007, 2010 & 2013:

.....

The different Excel file types provided by the latest versions of Excel make it clear when workbook contains macros, so this in itself is a useful security measure. However, Excel also has optional macro security settings, which are controlled via the options menu. These are :

'Disable all macros without notification'

• This setting does not allow any macros to run. When you open a new Excel workbook, you are not alerted to the fact that it contains macros, so you may not be aware that this is the reason a workbook does not work as expected.

'Disable all macros with notification'

• This setting prevents macros from running. However, if there are macros in a workbook, a pop-up is displayed, to warn you that the macros exist and have been disabled.

'Disable all macros except digitally signed macros'

• This setting only allow macros from trusted sources to run. All other macros do not run. When you open a new Excel workbook, you are not alerted to the fact that it contains macros, so you may not be aware that this is the reason a workbook does not work as expected.

'Enable all macros'

• This setting allows all macros to run. When you open a new Excel workbook, you are not alerted to the fact that it contains macros and may not be aware of macros running while you have the file open.

If you trust the macros and are ok with enabling them, select this option:

'Enable all macros'

and this dialog box should not show up for macros.

As for the dialog for saving, after noting that this was running on Excel for Mac 2011, I came across the following question on SO, StackOverflow - Suppress dialog when using VBA to save a macro containing Excel file (.xlsm) as a non macro containing file (.xlsx). From it, removing the dialog does not seem to be possible, except for possibly by some Keyboard Input simulation. I would post another question to inquire about that. Sorry I could only get you halfway. The other option would be to use a Windows computer with Microsoft Excel, though I'm not sure if that is a option for you in this case.

You'll have to include/require the class anyway, otherwise PHP won't know about the namespace.
You don't necessary have to do it in the same file though. You can do it in a bootstrap file for example. (or use an autoloader, but that's not the topic actually)

The idea of why scroll view is not scrolling because you set the content size for scrolling less than the size of the scroll view, which is wrong. You should set the content size bigger than the size of your scroll view to navigate through it while scrolling.

The same idea with zooming, you set the min and max value for zooming which will applied through zooming action.

welcome :)

Note for anybody who may have had problems with the cvWaitKey( ) function. If you are finding that cvWaitKey(x) is not waiting at all, make sure you actually have a window open (i.e. cvNamedWindow(...)). Put the cvNamedWindow(...) declaration BEFORE any cvWaitKey() function calls.

use Object.keys:

Object.keys(this.formErrors).map(key => {
  this.formErrors[key] = '';
  const control = form.get(key);

  if(control && control.dirty && !control.valid) {
    const messages = this.validationMessages[key];
    Object.keys(control.errors).map(key2 => {
      this.formErrors[key] += messages[key2] + ' ';
    });
  }
});

Just putting it in src/main/resources will bundle it inside the artifact. E.g. if your artifact is a JAR, you will have the log4j.properties file inside it, losing its initial point of making logging configurable.

I usually put it in src/main/resources, and set it to be output to target like so:

<build>
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <targetPath>${project.build.directory}</targetPath>
            <includes>
                <include>log4j.properties</include>
            </includes>
        </resource>
    </resources>
</build>

Additionally, in order for log4j to actually see it, you have to add the output directory to the class path. If your artifact is an executable JAR, you probably used the maven-assembly-plugin to create it. Inside that plugin, you can add the current folder of the JAR to the class path by adding a Class-Path manifest entry like so:

<plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <configuration>
        <archive>
            <manifest>
                <mainClass>com.your-package.Main</mainClass>
            </manifest>
            <manifestEntries>
                <Class-Path>.</Class-Path>
            </manifestEntries>
        </archive>
        <descriptorRefs>
            <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
    </configuration>
    <executions>
        <execution>
            <id>make-assembly</id> <!-- this is used for inheritance merges -->
            <phase>package</phase> <!-- bind to the packaging phase -->
            <goals>
                <goal>single</goal>
            </goals>
        </execution>
    </executions>
</plugin>

Now the log4j.properties file will be right next to your JAR file, independently configurable.

To run your application directly from Eclipse, add the resources directory to your classpath in your run configuration: Run->Run Configurations...->Java Application->New select the Classpath tab, select Advanced and browse to your src/resources directory.

The syntax you are using is new to SQL Server 2008:

INSERT INTO [MyDB].[dbo].[MyTable]
       ([FieldID]
       ,[Description])
 VALUES
       (1000,N'test'),(1001,N'test2')

For SQL Server 2005, you will have to use multiple INSERT statements:

INSERT INTO [MyDB].[dbo].[MyTable]
       ([FieldID]
       ,[Description])
 VALUES
       (1000,N'test')

INSERT INTO [MyDB].[dbo].[MyTable]
       ([FieldID]
       ,[Description])
 VALUES
       (1001,N'test2')

One other option is to use UNION ALL:

INSERT INTO [MyDB].[dbo].[MyTable]
       ([FieldID]
       ,[Description])
SELECT 1000, N'test' UNION ALL
SELECT 1001, N'test2'

Nice answer you can find in book Learning Cocoa with Objective-C (ISBN: 978-1-491-90139-7)

Modules are a new means of including and linking files and libraries into your projects. To understand how modules work and what benefits they have, it is important to look back into the history of Objective-C and the #import statement Whenever you want to include a file for use, you will generally have some code that looks like this:

#import "someFile.h"

Or in the case of frameworks:

#import <SomeLibrary/SomeFile.h>

Because Objective-C is a superset of the C programming language, the #import state- ment is a minor refinement upon C’s #include statement. The #include statement is very simple; it copies everything it finds in the included file into your code during compilation. This can sometimes cause significant problems. For example, imagine you have two header files: SomeFileA.h and SomeFileB.h; SomeFileA.h includes SomeFileB.h, and SomeFileB.h includes SomeFileA.h. This creates a loop, and can confuse the coimpiler. To deal with this, C programmers have to write guards against this type of event from occurring.

When using #import, you don’t need to worry about this issue or write header guards to avoid it. However, #import is still just a glorified copy-and-paste action, causing slow compilation time among a host of other smaller but still very dangerous issues (such as an included file overriding something you have declared elsewhere in your own code.)

Modules are an attempt to get around this. They are no longer a copy-and-paste into source code, but a serialised representation of the included files that can be imported into your source code only when and where they’re needed. By using modules, code will generally compile faster, and be safer than using either #include or #import.

Returning to the previous example of importing a framework:

#import <SomeLibrary/SomeFile.h>

To import this library as a module, the code would be changed to:

@import SomeLibrary;

This has the added bonus of Xcode linking the SomeLibrary framework into the project automatically. Modules also allow you to only include the components you really need into your project. For example, if you want to use the AwesomeObject component in the AwesomeLibrary framework, normally you would have to import everything just to use the one piece. However, using modules, you can just import the specific object you want to use:

@import AwesomeLibrary.AwesomeObject;

For all new projects made in Xcode 5, modules are enabled by default. If you want to use modules in older projects (and you really should) they will have to be enabled in the project’s build settings. Once you do that, you can use both #import and @import statements in your code together without any concern.

XmlDocument doc = new XmlDocument();
doc.LoadXml(str);

Where str is your XML string. See the MSDN article for more info.

If you have only these regular shapes, there is a simple procedure as follows :

1. Find Contours in the image ( image should be binary as given in your question)
2. Approximate each contour using approxPolyDP function.
3. First, check number of elements in the approximated contours of all the shapes. It is to recognize the shape. For eg, square will have 4, pentagon will have 5. Circles will have more, i don't know, so we find it. ( I got 16 for circle and 9 for half-circle.)
4. Now assign the color, run the code for your test image, check its number, fill it with corresponding colors.

Below is my example in Python:

import numpy as np
import cv2

img = cv2.imread('shapes.png')
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

ret,thresh = cv2.threshold(gray,127,255,1)

contours,h = cv2.findContours(thresh,1,2)

for cnt in contours:
    approx = cv2.approxPolyDP(cnt,0.01*cv2.arcLength(cnt,True),True)
    print len(approx)
    if len(approx)==5:
        print "pentagon"
        cv2.drawContours(img,[cnt],0,255,-1)
    elif len(approx)==3:
        print "triangle"
        cv2.drawContours(img,[cnt],0,(0,255,0),-1)
    elif len(approx)==4:
        print "square"
        cv2.drawContours(img,[cnt],0,(0,0,255),-1)
    elif len(approx) == 9:
        print "half-circle"
        cv2.drawContours(img,[cnt],0,(255,255,0),-1)
    elif len(approx) > 15:
        print "circle"
        cv2.drawContours(img,[cnt],0,(0,255,255),-1)

cv2.imshow('img',img)
cv2.waitKey(0)
cv2.destroyAllWindows()

Below is the output:

Remember, it works only for regular shapes.

Alternatively to find circles, you can use houghcircles. You can find a tutorial here.

Regarding iOS, OpenCV devs are developing some iOS samples this summer, So visit their site : www.code.opencv.org and contact them.

You can find slides of their tutorial here : http://code.opencv.org/svn/gsoc2012/ios/trunk/doc/CVPR2012_OpenCV4IOS_Tutorial.pdf
