Remember that in order to query the IEnumerable you need to reference system.linq.
It will give you the extension object needed to do:

CaimsList.FirstOrDefault(x=>x.Type =="variableName").toString();

Maybe you find this simpler

select * from (
    select ssn, sum(time) from downloads
    group by ssn
    order by sum(time) desc
) where rownum <= 10 --top 10 downloaders

p is a pointer variable. Its value is the address of i. When you call f, you pass the value of p, which is the address of i.

I've tried a select statement now with a PreparedStatement, but it turned out that it was not faster than the Jdbc template. Maybe, as mezmo suggested, it automatically creates prepared statements.

Anyway, the reason for my sql SELECTs being so slow was another one. In the WHERE clause I always used the operator LIKE, when all I wanted to do was finding an exact match. As I've found out LIKE searches for a pattern and therefore is pretty slow.

I'm using the operator = now and it's much faster.

You could use my JavaScript hash table implementation, jshashtable. It allows any object to be used as a key, not just strings.

If you wish dialog box to be re-activated for the page you set as prevent dialog box to show.

Chrome: select settings, a google page for chrome will open with all your settings for chrome.

At the very bottom, go to advance settings and at the bottom of the advance settings you may click on Resset Browser Settings... this will make dialog box appear as they should.

It also depends on what you need. For basic SQL transactions you could try doing TSQL transactions by using BEGIN TRANS and COMMIT TRANS in your code. That is the easiest way but it does have complexity and you have to be careful to commit properly (and rollback).

I would use something like

SQLTransaction trans = null;
using(trans = new SqlTransaction)
{
    ...
    Do SQL stuff here passing my trans into my various SQL executers
    ...
    trans.Commit  // May not be quite right
}

Any failure will pop you right out of the using and the transaction will always commit or rollback (depending on what you tell it to do). The biggest problem we faced was making sure it always committed. The using ensures the scope of the transaction is limited.

My SQL supports the function of a substring_Index where it will return the postion of a value in a string for the n occurance. A similar User defined function could be written to achieve this. Example in the link

Alternatively you could use charindex function call it x times to report the location of each _ given a starting postion +1 of the previously found instance. until a 0 is found

Edit: NM Charindex is the correct function

I was having this issue when viewing my website on a phone. While I was trying to close the overlay, I was pretty much clicking on anything under the overlay. A solution that I found working for myself is to just add a tag around the entire overlay

void foo() {
  /* do some stuff */
  if (!condition) {
    return;
  }
}

You can just use the return keyword just like you would in any other function.

In c, you could use fopen, and getch. Usually, if you can't be exactly sure of the length of the longest line, you could allocate a large buffer (e.g. 8kb) and almost be guaranteed of getting all lines.

If there's a chance you may have really really long lines and you have to process line by line, you could malloc a resonable buffer, and use realloc to double it's size each time you get close to filling it.

#include <stdio.h>
#include <stdlib.h>

void handle_line(char *line) {
  printf("%s", line);
}

int main(int argc, char *argv[]) {
    int size = 1024, pos;
    int c;
    char *buffer = (char *)malloc(size);

    FILE *f = fopen("myfile.txt", "r");
    if(f) {
      do { // read all lines in file
        pos = 0;
        do{ // read one line
          c = fgetc(f);
          if(c != EOF) buffer[pos++] = (char)c;
          if(pos >= size - 1) { // increase buffer length - leave room for 0
            size *=2;
            buffer = (char*)realloc(buffer, size);
          }
        }while(c != EOF && c != '\n');
        buffer[pos] = 0;
        // line is now in buffer
        handle_line(buffer);
      } while(c != EOF); 
      fclose(f);           
    }
    free(buffer);
    return 0;
}

You can use something like this:

List<Object[]> list = em.createQuery("SELECT p.field1, p.field2 FROM Entity p").getResultList();

then you can iterate over it:

for (Object[] obj : list){
    System.out.println(obj[0]);
    System.out.println(obj[1]);
}

BUT if you have only one field in query, you get a list of the type not from Object[]

Swift 2.0 Compability

func listWithFilter () {

    let fileManager = NSFileManager.defaultManager()
           // We need just to get the documents folder url
    let documentsUrl = fileManager.URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)[0] as NSURL

    do {
    // if you want to filter the directory contents you can do like this:
    if let directoryUrls = try? NSFileManager.defaultManager().contentsOfDirectoryAtURL(documentsUrl, includingPropertiesForKeys: nil, options: NSDirectoryEnumerationOptions.SkipsSubdirectoryDescendants) {
        print(directoryUrls)
       ........
        }

    }

}

OR

 func listFiles() -> [String] {

    var theError = NSErrorPointer()
    let dirs = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.AllDomainsMask, true) as? [String]
    if dirs != nil {
        let dir = dirs![0]
        do {
        let fileList = try NSFileManager.defaultManager().contentsOfDirectoryAtPath(dir)
        return fileList as [String]
        }catch {

        }

    }else{
        let fileList = [""]
        return fileList
    }
    let fileList = [""]
    return fileList

}

The easiest way is to let NPM do everything for you,

npm --add-python-to-path='true' --debug install --global windows-build-tools

You can only do this if you are connecting to a DNS server for the domain -and- AXFR is enabled for your IP address. This is the mechanism that secondary systems use to load a zone from the primary. In the old days, this was not restricted, but due to security concerns, most primary name servers have a whitelist of: secondary name servers + a couple special systems.

If the nameserver you are using allows this then you can use dig or nslookup.

For example:

#nslookup

>ls domain.com

NOTE: because nslookup is being deprecated for dig and other newere tools, some versions of nslookup do not support "ls", most notably Mac OS X's bundled version.

The --target switch is the thing you're looking for:

pip install --target=d:\somewhere\other\than\the\default package_name

But you still need to add d:\somewhere\other\than\the\default to PYTHONPATH to actually use them from that location.

-t, --target <dir>
Install packages into <dir>. By default this will not replace existing files/folders in <dir>.
Use --upgrade to replace existing packages in <dir> with new versions.

Upgrade pip if target switch is not available:

On Linux or OS X:

pip install -U pip

On Windows (this works around an issue):

python -m pip install -U pip

First of all, a warning: what follows is strictly in the realm of ugly, undocumented hacks. Do not rely on this working - even if it works for you now, it may stop working tomorrow, with any minor or major .NET update.

You can use the information in this article on CLR internals MSDN Magazine Issue 2005 May - Drill Into .NET Framework Internals to See How the CLR Creates Runtime Objects - last I checked, it was still applicable. Here's how this is done (it retrieves the internal "Basic Instance Size" field via TypeHandle of the type).

object obj = new List<int>(); // whatever you want to get the size of
RuntimeTypeHandle th = obj.GetType().TypeHandle;
int size = *(*(int**)&th + 1);
Console.WriteLine(size);

This works on 3.5 SP1 32-bit. I'm not sure if field sizes are the same on 64-bit - you might have to adjust the types and/or offsets if they are not.

This will work for all "normal" types, for which all instances have the same, well-defined types. Those for which this isn't true are arrays and strings for sure, and I believe also StringBuilder. For them you'll have add the size of all contained elements to their base instance size.

I think that this below is accurate and it may help. Feel free to correct it if you find any errors. I'm new at C.

char str[]  

1. array of values of type char, with its own address in memory
2. array of values of type char, with its own address in memory as many consecutive addresses as elements in the array

3. including termination null character '\0' &str, &str[0] and str, all three represent the same location in memory which is address of the first element of the array str

   char *strPtr = &str[0]; //declaration and initialization

alternatively, you can split this in two:

char *strPtr; strPtr = &str[0];

4. strPtr is a pointer to a char
5. strPtr points at array str
6. strPtr is a variable with its own address in memory
7. strPtr is a variable that stores value of address &str[0]
8. strPtr own address in memory is different from the memory address that it stores (address of array in memory a.k.a &str[0])
9. &strPtr represents the address of strPtr itself

I think that you could declare a pointer to a pointer as:

char **vPtr = &strPtr;  

declares and initializes with address of strPtr pointer

Alternatively you could split in two:

char **vPtr;
*vPtr = &strPtr

10. *vPtr points at strPtr pointer
11. *vPtr is a variable with its own address in memory
12. *vPtr is a variable that stores value of address &strPtr
13. final comment: you can not do str++, str address is a const, but you can do strPtr++

This thread helped me create my own solution that I will share here. I was using a GET ajax request at first without issues but it got to a point where the request URL length was exceeded so I had to swith to a POST.

The javascript uses JQuery file download plugin and consists of 2 succeeding calls. One POST (To send params) and one GET to retreive the file.

 function download(result) {
        $.fileDownload(uri + "?guid=" + result,
        {
            successCallback: onSuccess.bind(this),
            failCallback: onFail.bind(this)
        });
    }

    var uri = BASE_EXPORT_METADATA_URL;
    var data = createExportationData.call(this);

    $.ajax({
        url: uri,
        type: 'POST',
        contentType: 'application/json',
        data: JSON.stringify(data),
        success: download.bind(this),
        fail: onFail.bind(this)
    });

Server side

    [HttpPost]
    public string MassExportDocuments(MassExportDocumentsInput input)
    {
        // Save query for file download use
        var guid = Guid.NewGuid();
        HttpContext.Current.Cache.Insert(guid.ToString(), input, null, DateTime.Now.AddMinutes(5), Cache.NoSlidingExpiration);
        return guid.ToString();
    }

   [HttpGet]
    public async Task<HttpResponseMessage> MassExportDocuments([FromUri] Guid guid)
    {
        //Get params from cache, generate and return
        var model = (MassExportDocumentsInput)HttpContext.Current.Cache[guid.ToString()];
          ..... // Document generation

        // to determine when file is downloaded
        HttpContext.Current
                   .Response
                   .SetCookie(new HttpCookie("fileDownload", "true") { Path = "/" });

        return FileResult(memoryStream, "documents.zip", "application/zip");
    }

Surprisingly, readonly can actually result in slower code, as Jon Skeet found when testing his Noda Time library. In this case, a test that ran in 20 seconds took only 4 seconds after removing readonly.

moveBus() is getting called before initialize(). Try putting that line at the end of your initialize() function. Also Lat/Lon 0,0 is off the map (it's coordinates, not pixels), so you can't see it when it moves. Try 54,54. If you want the center of the map to move to the new location, use panTo().

I would say foreach is the standard way, though it obviously depends on what you're looking for

foreach(var kvp in my_dictionary) {
  ...
}

Is that what you're looking for?

As for me, it's a bad and quick solution for your problem :

android { 
  lintOptions { 
    abortOnError false 
  }
}

Better solution is solving problem in your code, because lint tool checks your Android project source files for potential bugs and optimization improvements for correctness, security, performance, usability, accessibility, and internationalization.

This problem most frequently occurring when:

• Layout include unresolved symbols or missing some attribute
• Other structural issues, such as use of deprecated elements or API calls that are not supported by the target API versions, might lead to code failing to run correctly.

Find your bugs by Inspect Code in Android Studio: Improve Your Code with Lint

You can select a code snippet and use right click menu to choose the action "Execute Selection in console".

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

=RIGHT(A1, 4)

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

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

=RIGHT(TRIMSPACES(A1), 4)

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

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

A shorter sample code for Json.Net library

private static string FormatJson(string json)
{
    dynamic parsedJson = JsonConvert.DeserializeObject(json);
    return JsonConvert.SerializeObject(parsedJson, Formatting.Indented);
}

Your javascript is executed before the HTML is generated, so it doesn't "see" the ungenerated INPUT elements. For jQuery, you would either stick the Javascript at the end of the HTML or wrap it like this:

<script type="text/javascript">   $(function() { //jQuery trick to say after all the HTML is parsed.     $("input[type=radio]").click(function() {       var total = 0;       $("input[type=radio]:checked").each(function() {         total += parseFloat($(this).val());       });        $("#totalSum").val(total);     });   }); </script> 

EDIT: This code works for me

<!DOCTYPE html> <html> <head> <meta charset="utf-8"> </head> <body>   <strong>Choose a base package:</strong>   <input id="item_0" type="radio" name="pkg" value="1942" />Base Package 1 - $1942   <input id="item_1" type="radio" name="pkg" value="2313" />Base Package 2 - $2313   <input id="item_2" type="radio" name="pkg" value="2829" />Base Package 3 - $2829   <strong>Choose an add on:</strong>   <input id="item_10" type="radio" name="ext" value="0" />No add-on - +$0   <input id="item_12" type="radio" name="ext" value="2146" />Add-on 1 - (+$2146)   <input id="item_13" type="radio" name="ext" value="2455" />Add-on 2 - (+$2455)   <input id="item_14" type="radio" name="ext" value="2764" />Add-on 3 - (+$2764)   <input id="item_15" type="radio" name="ext" value="3073" />Add-on 4 - (+$3073)   <input id="item_16" type="radio" name="ext" value="3382" />Add-on 5 - (+$3382)   <input id="item_17" type="radio" name="ext" value="3691" />Add-on 6 - (+$3691)   <strong>Your total is:</strong>   <input id="totalSum" type="text" name="totalSum" readonly="readonly" size="5" value="" />   <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>   <script type="text/javascript">       $("input[type=radio]").click(function() {         var total = 0;         $("input[type=radio]:checked").each(function() {           total += parseFloat($(this).val());         });          $("#totalSum").val(total);       });     </script> </body> </html> 

I m not satisfied by the best answer by the Joseph, instead of fixing the correct problem, he told that this is wrong use case. In fact there are many places for example if you are converting an old codebase to ajaxified code and there you NEED it, then you NEED it. In programming there is no excuse because its not only you who is coding its all bad and good developers and you have to work side by side. So if I don't code redirection in ajax my fellow developer can force me to have a solution for it. Just like I like to use all AMD patterned sites or mvc4, and my company can keep me away from it for a year.

So let's talk on the solution now.

I have done hell heck of ajax request and response handling and the simplest way I found out was to send status codes to the client and have one standard javascript function to understand those codes. If i simply send for example code 13 it might meant a redirect.

So a json response like { statusCode: 13, messsage: '/home/logged-in' } of course there are tons of variations proposed like { status: 'success', code: 13, url: '/home/logged-in', message: 'You are logged in now' }

etc , so up to your own choice of standard messages

Usually I Inherit from base Controller class and put my choice of standard responses like this

public JsonResult JsonDataResult(object data, string optionalMessage = "")
    {
        return Json(new { data = data, status = "success", message = optionalMessage }, JsonRequestBehavior.AllowGet);
    }

    public JsonResult JsonSuccessResult(string message)
    {
        return Json(new { data = "", status = "success", message = message }, JsonRequestBehavior.AllowGet);
    }

    public JsonResult JsonErrorResult(string message)
    {
        return Json(new { data = "", status = "error", message = message }, JsonRequestBehavior.AllowGet);
    }

    public JsonResult JsonRawResult(object data)
    {
        return Json(data, JsonRequestBehavior.AllowGet);
    }

About using $.ajax intead of Ajax.BeginForm I would love to use Jquery ajax and I do, but again its not me in the whole world to make decisions I have an application full of Ajax.BeginForm and of course I didnt do that. But i have to live with it.

So There is a success callback in begin form too, you don't need to use jquery ajax to use callbacks Something about it here Ajax.BeginForm, Calls Action, Returns JSON, How do I access JSON object in my OnSuccess JS Function?

Thanks

The following should do what you want:

x <- data.frame(X1=sample(c(1:3,NaN), 200, replace=TRUE), X2=sample(c(4:6,NaN), 200, replace=TRUE))
head(x)
x <- replace(x, is.na(x), 0)
head(x)

I used pychart and thought it was very straightforward.

http://home.gna.org/pychart/

It's all native python and does not have a busload of dependencies. I'm sure matplotlib is lovely but I'd be downloading and installing for days and I just want one measley bar chart!

It doesn't seem to have been updated in a few years but hey it works!

There are jQuery events like keyup and keypress which you can use with input HTML Elements. You could additionally use the blur() event.

It isn't bad practice, but it can make code less readable. One useful refactoring to work around this is to move the loop to a separate method, and then use a return statement instead of a break, for example this (example lifted from @Chris's answer):

String item;

for(int x = 0; x < 10; x++)
{
    // Linear search.
    if(array[x].equals("Item I am looking for"))
    {
        //you've found the item. Let's stop.
        item = array[x];
        break; 
    }
}

can be refactored (using extract method) to this:

public String searchForItem(String itemIamLookingFor)
{
    for(int x = 0; x < 10; x++)
    {
        if(array[x].equals(itemIamLookingFor))
        {
            return array[x];
        }
    }
}

Which when called from the surrounding code can prove to be more readable.

Put your code in a string, iterate, eval, setTimeout and recursion to continue with the remaining lines. No doubt I'll refine this or just throw it out if it doesn't hit the mark. My intention is to use it to simulate really, really basic user testing.

The recursion and setTimeout make it sequential.

Thoughts?

var line_pos = 0;
var string =`
    console.log('123');
    console.log('line pos is '+ line_pos);
SLEEP
    console.log('waited');
    console.log('line pos is '+ line_pos);
SLEEP
SLEEP
    console.log('Did i finish?');
`;

var lines = string.split("\n");
var r = function(line_pos){
    for (i = p; i < lines.length; i++) { 
        if(lines[i] == 'SLEEP'){
            setTimeout(function(){r(line_pos+1)},1500);
            return;
        }
        eval (lines[line_pos]);
    }
    console.log('COMPLETED READING LINES');
    return;
}
console.log('STARTED READING LINES');
r.call(this,line_pos);

OUTPUT

You asked for differences, but you can’t quite compare those two.

Note that <meta http-equiv="content-language" content="es"> is obsolete and removed in HTML5. It was used to specify “a document-wide default language”, with its http-equiv attribute making it a pragma directive (which simulates an HTTP response header like Content-Language that hasn’t been sent from the server, since it cannot override a real one).

Regarding <meta name="language" content="Spanish">, you hardly find any reliable information. It’s non-standard and was probably invented as a SEO makeshift.

However, the HTML5 W3C Recommendation encourages authors to use the lang attribute on html root elements (attribute values must be valid BCP 47 language tags):

<!DOCTYPE html>
<html lang="es-ES">
    <head>
        …

Anyway, if you want to specify the content language to instruct search engine robots, you should consider this quote from Google Search Console Help on multilingual sites:

Google uses only the visible content of your page to determine its language. We don’t use any code-level language information such as lang attributes.

dochoffiday's answer is a great starting point, but for me it did not cut it (the CSS part needed a buff) so I made a modified version with several improvements.

            $this.find("td").addClass("ui-widget-content");
            $this.find("tr:last-child").addClass("last-child");
        });
    };
})(jQuery);

Differences with the original version:

• the default CSS class has been changed to ui-styled-table (it sounds more consistent)
• the .live call was replaced with the recommended .on for jQuery 1.7 upwards
• the explicit conditional has been replaced by .toggleClass (a terser equivalent)
• code that sets the misleadingly-named CSS class first on table cells has been removed
• the code that dynamically adds .last-child to the last table row is necessary to fix a visual glitch on Internet Explorer 7 and Internet Explorer 8; for browsers that support :last-child it is not necessary

CSS

/* Internet Explorer 7: setting "separate" results in bad visuals; all other browsers work fine with either value. */
/* If set to "separate", then this rule is also needed to prevent double vertical borders on hover:
table.ui-styled-table tr * + th, table.ui-styled-table tr * + td  { border-left-width: 0px !important; } */
table.ui-styled-table { border-collapse: collapse; }

/* Undo the "bolding" that jQuery UI theme may cause on hovered elements
/* Internet Explorer 7: does not support "inherit", so use a MS proprietary expression along with an Internet Explorer <= 7 targeting hack
        to make the visuals consistent across all supported browsers */
table.ui-styled-table td.ui-state-hover {
    font-weight: inherit;
    *font-weight: expression(this.parentNode.currentStyle['fontWeight']);
}

/* Initally remove bottom border for all cells. */
table.ui-styled-table th, table.ui-styled-table td { border-bottom-width: 0px !important; }

/* Hovered-row cells should show bottom border (will be highlighted) */
table.ui-styled-table tbody tr:hover th,
table.ui-styled-table tbody tr:hover td
{ border-bottom-width: 1px !important; }

/* Remove top border if the above row is being hovered to prevent double horizontal borders. */
table.ui-styled-table tbody tr:hover + tr th,
table.ui-styled-table tbody tr:hover + tr td
{ border-top-width: 0px !important; }

/* Last-row cells should always show bottom border (not necessarily highlighted if not hovered). */
/* Internet Explorer 7, Internet Explorer 8: selector dependent on CSS classes because of no support for :last-child */
table.ui-styled-table tbody tr.last-child th,
table.ui-styled-table tbody tr.last-child td
{ border-bottom-width: 1px !important; }

/* Last-row cells should always show bottom border (not necessarily highlighted if not hovered). */
/* Internet Explorer 8 BUG: if these (unsupported) selectors are added to a rule, other selectors for that rule will stop working as well! */
/* Internet Explorer 9 and later, Firefox, Chrome: make sure the visuals are working even without the CSS classes crutch. */
table.ui-styled-table tbody tr:last-child th,
table.ui-styled-table tbody tr:last-child td
{ border-bottom-width: 1px !important; }

Notes

I have tested this on Internet Explorer 7 and upwards, Firefox 11 and Google Chrome 18 and confirmed that it works perfectly. I have not tested reasonably earlier versions of Firefox and Chrome or any version of Opera; however, those browsers are well-known for good CSS support and since we are not using any bleeding-edge functionality here I assume it will work just fine there as well.

If you are not interested in Internet Explorer 7 support there is one CSS attribute (introduced with the star hack) that can go.

If you are not interested in Internet Explorer 8 support either, the CSS and JavaScript related to adding and targeting the last-child CSS class can go as well.

If you are using bootstrap-datepicker you may use this style:

$('#datepicker').datepicker('setStartDate', "01-01-1900");

REST stands for REpresentational State Transfer and goes a little something like this:

We have a bunch of uniquely addressable 'entities' that we want made available via a web application. Those entities each have some identifier and can be accessed in various formats. REST defines a bunch of stuff about what GET, POST, etc mean for these purposes.

the basic idea with REST is that you can attach a bunch of 'renderers' to different entities so that they can be available in different formats easily using the same HTTP verbs and url formats.

For more clarification on what RESTful means and how it is used google rails. Rails is a RESTful framework so there's loads of good information available in its docs and associated blog posts. Worth a read even if you arent keen to use the framework. For example: http://www.sitepoint.com/restful-rails-part-i/

RESTless means not restful. If you have a web app that does not adhere to RESTful principles then it is not RESTful

Instead, you can open particular app's general settings with one line

 startActivity(new Intent(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS, Uri.parse("package:" + BuildConfig.APPLICATION_ID)));

You cannot use the Restore menu in MySQL Admin if the backup / dump wasn't created from there. It's worth a shot though. If you choose to "ignore errors" with the checkbox for that, it will say it completed successfully, although it clearly exits with only a fraction of rows imported...this is with a dump, mind you.

if test -e "$file_name";then
 ...
fi

if grep -q "poet" $file_name; then
  ..
fi

I found this article enlightening : Javascript Madness: Query String Parsing

I found it when I was trying to undersand why decodeURIComponent was not decoding '+' correctly. Here is an extract:

String:                         "A + B"
Expected Query String Encoding: "A+%2B+B"
escape("A + B") =               "A%20+%20B"     Wrong!
encodeURI("A + B") =            "A%20+%20B"     Wrong!
encodeURIComponent("A + B") =   "A%20%2B%20B"   Acceptable, but strange

Encoded String:                 "A+%2B+B"
Expected Decoding:              "A + B"
unescape("A+%2B+B") =           "A+++B"       Wrong!
decodeURI("A+%2B+B") =          "A+++B"       Wrong!
decodeURIComponent("A+%2B+B") = "A+++B"       Wrong!

You can additionally implement IDataErrorInfo as follows in the view model. If you implement IDataErrorInfo, you can do the validation in that instead of the setter of a particular property, then whenever there is a error, return an error message so that the text box which has the error gets a red box around it, indicating an error.

class ViewModel : INotifyPropertyChanged, IDataErrorInfo
{
    private string m_Name = "Type Here";
    public ViewModel()
    {
    }

    public string Name
    {
        get
        {
            return m_Name;
        }
        set
        {
            if (m_Name != value)
            {
                m_Name = value;
                OnPropertyChanged("Name");
            }
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;

    protected void OnPropertyChanged(string propertyName)
    {
        if (PropertyChanged != null)
        {
            PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
        }
    }

    public string Error
    {
        get { return "...."; }
    }

    /// <summary>
    /// Will be called for each and every property when ever its value is changed
    /// </summary>
    /// <param name="columnName">Name of the property whose value is changed</param>
    /// <returns></returns>
    public string this[string columnName]
    {
        get 
        {
            return Validate(columnName);
        }
    }

    private string Validate(string propertyName)
    {
        // Return error message if there is error on else return empty or null string
        string validationMessage = string.Empty;
        switch (propertyName)
        {
            case "Name": // property name
                // TODO: Check validiation condition
                validationMessage = "Error";
                break;
        }

        return validationMessage;
    }
}

And you have to set ValidatesOnDataErrors=True in the XAML in order to invoke the methods of IDataErrorInfo as follows:

<TextBox Text="{Binding Name, UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=True}" />

I wanted to use an xml control file based on a class for my VB.net desktop WPF application. The above code to do this all in one is excellent and set me in the right direction. In case anyone is searching for a VB.net solution here is the class I built:

Imports System.IO
Imports System.Xml.Serialization

Public Class XControl

Private _person_ID As Integer
Private _person_UID As Guid

'load from file
Public Function XCRead(filename As String) As XControl
    Using sr As StreamReader = New StreamReader(filename)
        Dim xmls As New XmlSerializer(GetType(XControl))
        Return CType(xmls.Deserialize(sr), XControl)
    End Using
End Function

'save to file
Public Sub XCSave(filename As String)
    Using sw As StreamWriter = New StreamWriter(filename)
        Dim xmls As New XmlSerializer(GetType(XControl))
        xmls.Serialize(sw, Me)
    End Using
End Sub

'all the get/set is below here

Public Property Person_ID() As Integer
    Get
        Return _person_ID
    End Get
    Set(value As Integer)
        _person_ID = value
    End Set
End Property

Public Property Person_UID As Guid
    Get
        Return _person_UID
    End Get
    Set(value As Guid)
        _person_UID = value
    End Set
End Property

End Class

Same problem with Anaconda running on Ubuntu 15.10. I closed the terminal and opened a new window and it worked fine.

Emacs has comment-dwim (Do What I Mean) - just select the block and do a:

M-;

It's a toggle - use it to comment AND uncomment blocks.

If you don't have yaml-mode installed you will need to tell Emacs to use the hash character (#).

In Bash:

if [[ ( $g == 1 && $c == 123 ) || ( $g == 2 && $c == 456 ) ]]

I recently discovered an interesting trick that allows to "Split String With String As Delimiter", so I couldn't resist the temptation to post it here as a new answer. Note that "obviously the question wasn't accurate. Firstly, both string1 and string2 can contain spaces. Secondly, both string1 and string2 can contain ampersands ('&')". This method correctly works with the new specifications (posted as a comment below Stephan's answer).

@echo off
setlocal

set "str=string1&with spaces by string2&with spaces.txt"

set "string1=%str: by =" & set "string2=%"
set "string2=%string2:.txt=%"

echo "%string1%"
echo "%string2%"

For further details on the split method, see this post.

If you're interested in making .xlsx (Office 2007 and beyond) files, you're in luck. Office 2007+ uses OpenXML which for lack of a more apt description is XML files inside of a zip named .xlsx

Take an excel file (2007+) and rename it to .zip, you can open it up and take a look. If you're using .NET 3.5 you can use the System.IO.Packaging library to manipulate the relationships & zipfile itself, and linq to xml to play with the xml (or just DOM if you're more comfortable).

Otherwise id reccomend DotNetZip, a powerfull library for manipulation of zipfiles.

OpenXMLDeveloper has lots of resources about OpenXML and you can find more there.

If you want .xls (2003 and below) you're going to have to look into 3rd party libraries or perhaps learn the file format yourself to achieve this without excel installed.

The python interpreter will handle it for you, you just have to do your operations (+, -, *, /), and it will work as normal.

The int value is unlimited.

Careful when doing division, by default the quotient is turned into float, but float does not support such large numbers. If you get an error message saying float does not support such large numbers, then it means the quotient is too large to be stored in float you’ll have to use floor division (//).

It ignores any decimal that comes after the decimal point, this way, the result will be int, so you can have a large number result.

>>>10//3
3

>>>10//4
2

The above solutions explain clearly what the problem is; when you don't have control over the repo, the best way to submit your code is to create a Fork of the original repo and submit your code to this new repo so later you can push it to the original one.

1. Declare the variable
2. Set it by your command and add dynamic parts like use parameter values of sp(here @IsMonday and @IsTuesday are sp params)

3. execute the command

   declare  @sql varchar (100)
   set @sql ='select * from #td1'
   
   if (@IsMonday+@IsTuesday !='')
   begin
   set @sql= @sql+' where PickupDay in ('''+@IsMonday+''','''+@IsTuesday+''' )'
   end
   exec( @sql)
   

If you want to split a string into words, you can use explode() or str_word_count().

HTML:

<div  ng-repeat="scannedDevice in ScanResult">
        <!--GridStarts-->
          <div >
              <img ng-src={{'./assets/img/PlaceHolder/Test.png'}} 
                   <!--Pass Param-->
                   ng-click="connectDevice(scannedDevice.id)"
                   altSrc="{{'./assets/img/PlaceHolder/user_place_holder.png'}}" 
                   onerror="this.src = $(this).attr('altSrc')">
           </div>    
 </div>

Java Script:

   //Global Variables
    var  ANGULAR_APP = angular.module('TestApp',[]);

    ANGULAR_APP .controller('TestCtrl',['$scope', function($scope) {

      //Variables
      $scope.ScanResult = [];

      //Pass Parameter
      $scope.connectDevice = function(deviceID) {
            alert("Connecting : "+deviceID );
        };
     }]);

That's not a jQuery object, it's just an object.

You can use the hasOwnProperty method to check for a key:

if (obj.hasOwnProperty("key1")) {
  ...
}

You can create an inline view or a temporary table, fill it with you values and issue this:

SELECT  *
FROM    fiberbox f
JOIN    (
        SELECT '%1740%' AS cond
        UNION ALL
        SELECT '%1938%' AS cond
        UNION ALL
        SELECT '%1940%' AS cond
        ) ?
ON      f.fiberBox LIKE cond

This, however, can return you multiple rows for a fiberbox that is something like '1740, 1938', so this query can fit you better:

SELECT  *
FROM    fiberbox f
WHERE   EXISTS
        (
        SELECT  1
        FROM    (
                SELECT '%1740%' AS cond
                UNION ALL
                SELECT '%1938%' AS cond
                UNION ALL
                SELECT '%1940%' AS cond
                ) ?
        WHERE   f.fiberbox LIKE cond
        )

Java Heap Memory is part of memory allocated to JVM by Operating System.

Objects reside in an area called the heap. The heap is created when the JVM starts up and may increase or decrease in size while the application runs. When the heap becomes full, garbage is collected.

You can find more details about Eden Space, Survivor Space, Tenured Space and Permanent Generation in below SE question:

Young , Tenured and Perm generation

PermGen has been replaced with Metaspace since Java 8 release.

Regarding your queries:

1. Eden Space, Survivor Space, Tenured Space are part of heap memory
2. Metaspace and Code Cache are part of non-heap memory.

Codecache: The Java Virtual Machine (JVM) generates native code and stores it in a memory area called the codecache. The JVM generates native code for a variety of reasons, including for the dynamically generated interpreter loop, Java Native Interface (JNI) stubs, and for Java methods that are compiled into native code by the just-in-time (JIT) compiler. The JIT is by far the biggest user of the codecache.

Microsoft provides a walkthrough for creating a Windows Explorer style interface in C#.

There are also several examples on Code Project and other sites. Immediate examples are Explorer Tree, My Explorer, File Browser and Advanced File Explorer but there are others. Explorer Tree seems to look the best from the brief glance I took.

I used the search term windows explorer tree view C# in Google to find these links.

Your equals2() method always will return the same as equals() !!

Your code with my comments:

public boolean equals2(Object object2) {  // equals2 method
    if(a.equals(object2)) { // if equals() method returns true
        return true; // return true
    }
    else return false; // if equals() method returns false, also return false
}

select partition_name,column_name,high_value,partition_position
from ALL_TAB_PARTITIONS a , ALL_PART_KEY_COLUMNS b 
where table_name='YOUR_TABLE' and a.table_name = b.name;

This query lists the column name used as key and the allowed values. make sure, you insert the allowed values(high_value). Else, if default partition is defined, it would go there.

EDIT:

I presume, your TABLE DDL would be like this.

CREATE TABLE HE0_DT_INF_INTERFAZ_MES
  (
    COD_PAIS NUMBER,
    FEC_DATA NUMBER,
    INTERFAZ VARCHAR2(100)
  )
  partition BY RANGE(COD_PAIS, FEC_DATA)
  (
    PARTITION PDIA_98_20091023 VALUES LESS THAN (98,20091024)
  );

Which means I had created a partition with multiple columns which holds value less than the composite range (98,20091024);

That is first COD_PAIS <= 98 and Also FEC_DATA < 20091024

Combinations And Result:

98, 20091024     FAIL
98, 20091023     PASS
99, ********     FAIL
97, ********     PASS
 < 98, ********     PASS

So the below INSERT fails with ORA-14400; because (98,20091024) in INSERT is EQUAL to the one in DDL but NOT less than it.

SQL> INSERT INTO HE0_DT_INF_INTERFAZ_MES(COD_PAIS, FEC_DATA, INTERFAZ)
                                  VALUES(98, 20091024, 'CTA');  2
INSERT INTO HE0_DT_INF_INTERFAZ_MES(COD_PAIS, FEC_DATA, INTERFAZ)
            *
ERROR at line 1:
ORA-14400: inserted partition key does not map to any partition

But, we I attempt (97,20091024), it goes through

SQL> INSERT INTO HE0_DT_INF_INTERFAZ_MES(COD_PAIS, FEC_DATA, INTERFAZ)
  2                                    VALUES(97, 20091024, 'CTA');

1 row created.

Some common easy process from date object can be done by this.

var monthNames = ["January", "February", "March", "April", "May", "June",_x000D_
  "July", "August", "September", "October", "November", "December"_x000D_
];_x000D_
var monthShortNames = ["Jan", "Feb", "Mar", "Apr", "May", "Jun",_x000D_
  "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"_x000D_
];_x000D_
_x000D_
function dateFormat1(d) {_x000D_
  var t = new Date(d);_x000D_
  return t.getDate() + ' ' + monthNames[t.getMonth()] + ', ' + t.getFullYear();_x000D_
}_x000D_
_x000D_
function dateFormat2(d) {_x000D_
  var t = new Date(d);_x000D_
  return t.getDate() + ' ' + monthShortNames[t.getMonth()] + ', ' + t.getFullYear();_x000D_
}_x000D_
_x000D_
console.log(dateFormat1(new Date()))_x000D_
console.log(dateFormat2(new Date()))

Or you can make date prototype like

Date.prototype.getMonthName = function() {_x000D_
  var monthNames = ["January", "February", "March", "April", "May", "June",_x000D_
    "July", "August", "September", "October", "November", "December"_x000D_
  ];_x000D_
  return monthNames[this.getMonth()];_x000D_
}_x000D_
_x000D_
_x000D_
Date.prototype.getFormatDate = function() {_x000D_
  var monthNames = ["January", "February", "March", "April", "May", "June",_x000D_
    "July", "August", "September", "October", "November", "December"_x000D_
  ];_x000D_
  return this.getDate() + ' ' + monthNames[this.getMonth()] + ', ' + this.getFullYear();_x000D_
}_x000D_
_x000D_
_x000D_
console.log(new Date().getMonthName())_x000D_
console.log(new Date().getFormatDate())

Ex:

var dateFormat3 = new Date().getMonthName(); # March

var dateFormat4 = new Date().getFormatDate(); # 16 March, 2017

Navigate the directory where you want to create the application and run the command:

PATH="Path where your node is installed";%PATH%

There seems to be a few details left out of your explanation, but I will do my best...

If these are NUL-terminated strings or the memory is pre-zeroed, you can just iterate down the length of the memory segment until you hit a NUL (0) character or the maximum length (whichever comes first). Use the string constructor, passing the buffer and the size determined in the previous step.

string retrieveString( char* buf, int max ) {

    size_t len = 0;
    while( (len < max) && (buf[ len ] != '\0') ) {
        len++;
    }

    return string( buf, len );

}

If the above is not the case, I'm not sure how you determine where a string ends.

You may consider using configure_file with the COPYONLY option:

configure_file(<input> <output> COPYONLY)

Unlike file(COPY ...) it creates a file-level dependency between input and output, that is:

If the input file is modified the build system will re-run CMake to re-configure the file and generate the build system again.

with Scanner you need to check if there is a next line with hasNextLine()

so the loop becomes

while(sc.hasNextLine()){
    str=sc.nextLine();
    //...
}

it's readers that return null on EOF

ofcourse in this piece of code this is dependent on whether the input is properly formatted

I'd suggest using such extension method:

public static class DataColumnCollectionExtensions
{
    public static IEnumerable<DataColumn> AsEnumerable(this DataColumnCollection source)
    {
        return source.Cast<DataColumn>();
    }
}

And therefore:

string[] columnNames = dataTable.Columns.AsEnumerable().Select(column => column.Name).ToArray();

You may also implement one more extension method for DataTable class to reduce code:

public static class DataTableExtensions
{
    public static IEnumerable<DataColumn> GetColumns(this DataTable source)
    {
        return source.Columns.AsEnumerable();
    }
}

And use it as follows:

string[] columnNames = dataTable.GetColumns().Select(column => column.Name).ToArray();

Most of these answers work only for a simple case when you are not sending attachment. In my case I need sometimes to send attachment (ACTION_SEND) or two attachments (ACTION_SEND_MULTIPLE).

So I took best approaches from this thread and combined them. It's using support library's ShareCompat.IntentBuilder but I show only apps which match the ACTION_SENDTO with "mailto:" uri. This way I get only list of email apps with attachment support:

fun Activity.sendEmail(recipients: List<String>, subject: String, file: Uri, text: String? = null, secondFile: Uri? = null) {
    val originalIntent = createEmailShareIntent(recipients, subject, file, text, secondFile)
    val emailFilterIntent = Intent(Intent.ACTION_SENDTO, Uri.parse("mailto:"))
    val originalIntentResults = packageManager.queryIntentActivities(originalIntent, 0)
    val emailFilterIntentResults = packageManager.queryIntentActivities(emailFilterIntent, 0)
    val targetedIntents = originalIntentResults
            .filter { originalResult -> emailFilterIntentResults.any { originalResult.activityInfo.packageName == it.activityInfo.packageName } }
            .map {
                createEmailShareIntent(recipients, subject, file, text, secondFile).apply { `package` = it.activityInfo.packageName }
            }
            .toMutableList()
    val finalIntent = Intent.createChooser(targetedIntents.removeAt(0), R.string.choose_email_app.toText())
    finalIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, targetedIntents.toTypedArray())
    startActivity(finalIntent)
}

private fun Activity.createEmailShareIntent(recipients: List<String>, subject: String, file: Uri, text: String? = null, secondFile: Uri? = null): Intent {
    val builder = ShareCompat.IntentBuilder.from(this)
            .setType("message/rfc822")
            .setEmailTo(recipients.toTypedArray())
            .setStream(file)
            .setSubject(subject)
    if (secondFile != null) {
        builder.addStream(secondFile)
    }
    if (text != null) {
        builder.setText(text)
    }
    return builder.intent
}

I think this is what you want:

REGEX_DATE='^\d{2}[/-]\d{2}[/-]\d{4}$'

echo "$1" | grep -P -q $REGEX_DATE
echo $?

I've used the -P switch to get perl regex.

Adding to jelovirt's answer, you can use number() to convert the value to a number, then round(), floor(), or ceiling() to get a whole integer.

Example

<xsl:variable name="MyValAsText" select="'5.14'"/>
<xsl:value-of select="number($MyValAsText) * 2"/> <!-- This outputs 10.28 -->
<xsl:value-of select="floor($MyValAsText)"/> <!-- outputs 5 -->
<xsl:value-of select="ceiling($MyValAsText)"/> <!-- outputs 6 -->
<xsl:value-of select="round($MyValAsText)"/> <!-- outputs 5 -->

No! There is no 64-bit version of Visual Studio.

How to know it is not 64-bit: Once you download Visual Studio and click the install button, you will see that the initialization folder it selects automatically is C:\Program Files (x86)\Microsoft Visual Studio 14.0

As per my understanding, all 64-bit programs/applications goes to C:\Program Files and all 32-bit applications goes to C:\Program Files (x86) from Windows 7 onwards.

It depends on the storage duration of the variable. A variable with static storage duration is always implicitly initialized with zero.

As for automatic (local) variables, an uninitialized variable has indeterminate value. Indeterminate value, among other things, mean that whatever "value" you might "see" in that variable is not only unpredictable, it is not even guaranteed to be stable. For example, in practice (i.e. ignoring the UB for a second) this code

int num;
int a = num;
int b = num;

does not guarantee that variables a and b will receive identical values. Interestingly, this is not some pedantic theoretical concept, this readily happens in practice as consequence of optimization.

So in general, the popular answer that "it is initialized with whatever garbage was in memory" is not even remotely correct. Uninitialized variable's behavior is different from that of a variable initialized with garbage.

in swift 3.0 this is how we can convert Int to String and String to Int

//convert Integer to String in Swift 3.0

let theIntegerValue :Int = 123  // this can be var also
let theStringValue :String = String(theIntegerValue)


//convert String to Integere in Swift 3.0


let stringValue : String = "123"
let integerValue : Int = Int(stringValue)!

• All as varchar (they aren't numbers but "collections of digits")
• Country + area + number separately
• Not all countries have area code (eg Malta where I am)
• Some countries drop the leading zero from the area code when dialling internal (eg UK)
• Format in the client code

You can also use Boost.Assignment:

const list<int> primes = list_of(2)(3)(5)(7)(11);

vector<int> v; 
v += 1,2,3,4,5,6,7,8,9;

The escape character in batch scripts is ^. But for double-quoted strings, double up the quotes:

"string with an embedded "" character"

Alternatively, you can bring variables in from the outside scope by using closures with the use keyword.

$myVar = "foo";
$myFunction = function($arg1, $arg2) use ($myVar)
{
 return $arg1 . $myVar . $arg2;
};

I had the same problem, the solution was set JAVA_HOME in environment variables.

The problem is the padding of the font on the textview. Just add to your textview:

android:includeFontPadding="false"

After looking at all the above solutions, the following was the quickest solution for me. If you are using angular-material:

 <md-datepicker ng-model="member.reg_date" md-placeholder="Enter date"></md-datepicker>

To set the format:

app.config(function($mdDateLocaleProvider) {
    $mdDateLocaleProvider.formatDate = function(date) {
        // Requires Moment.js OR enter your own formatting code here....
        return moment(date).format('DD-MM-YYYY');
    };
});

Edit: You also need to set the parseDate for typing in a date (from this answer Change format of md-datepicker in Angular Material)

$mdDateLocaleProvider.parseDate = function(dateString) {
    var m = moment(dateString, 'DD/MM/YYYY', true);
    return m.isValid() ? m.toDate() : new Date(NaN);
};

If you are interested in now only, then simply use:

Date d = new Date();

names=[line.strip() for line in open('names.txt')]

The CLR uses it when it is compiling at runtime. Here is a link to MSDN that explains further.

The Angular6 equivalent code should be:

app.component.html

<div (mouseover)="changeText=true" (mouseout)="changeText=false">
  <span *ngIf="!changeText">Hide</span>
  <span *ngIf="changeText">Show</span>
</div>

app.component.ts

@Component({
   selector: 'app-main',
   templateUrl: './app.component.html'
})
export class AppComponent {
    changeText: boolean;
    constructor() {
       this.changeText = false;
    }
}

Notice that there is no such thing as $scope anymore as it existed in AngularJS. Its been replaced with member variables from the component class. Also, there is no scope resolution algorithm based on prototypical inheritance either - it either resolves to a component class member, or it doesn't.

Written in Vanilla Javascript

     //Get URL
     var loc = window.location.href;
     console.log(loc);
     var index = loc.indexOf("?");
     console.log(loc.substr(index+1));
     var splitted = loc.substr(index+1).split('&');
     console.log(splitted);
     var paramObj = [];
     for(var i=0;i<splitted.length;i++){
         var params = splitted[i].split('=');
         var key = params[0];
         var value = params[1];
         var obj = {
             [key] : value
         };
         paramObj.push(obj);
         }
    console.log(paramObj);
    //Loop through paramObj to get all the params in query string.

The error comes when you try to call sum(x) and x is a factor.

What that means is that one of your columns, though they look like numbers are actually factors (what you are seeing is the text representation)

simple fix, convert to numeric. However, it needs an intermeidate step of converting to character first. Use the following:

family[, 1] <- as.numeric(as.character( family[, 1] ))
family[, 3] <- as.numeric(as.character( family[, 3] ))

For a detailed explanation of why the intermediate as.character step is needed, take a look at this question: How to convert a factor to integer\numeric without loss of information?

declare @testVal varchar(20)

set @testVal = '?t/es?ti/n*g 1*2?3*'

select @testVal = REPLACE(@testVal, item, '') from (select '?' item union select '*' union select '/') list

select @testVal;

Yes, you can use the native javascript Date() object and its methods.

For instance you can create a function like:

function formatDate(date) {
  var hours = date.getHours();
  var minutes = date.getMinutes();
  var ampm = hours >= 12 ? 'pm' : 'am';
  hours = hours % 12;
  hours = hours ? hours : 12; // the hour '0' should be '12'
  minutes = minutes < 10 ? '0'+minutes : minutes;
  var strTime = hours + ':' + minutes + ' ' + ampm;
  return (date.getMonth()+1) + "/" + date.getDate() + "/" + date.getFullYear() + "  " + strTime;
}

var d = new Date();
var e = formatDate(d);

alert(e);

And display also the am / pm and the correct time.

Remember to use getFullYear() method and not getYear() because it has been deprecated.

A static method means that it can be accessed without creating an object of the class, unlike public:

public class MyClass {
   // Static method
   static void myStaticMethod() {
      System.out.println("Static methods can be called without creating objects");
   }

  // Public method
  public void myPublicMethod() {
      System.out.println("Public methods must be called by creating objects");
   }

  // Main method
  public static void main(String[ ] args) {
      myStaticMethod(); // Call the static method
    // myPublicMethod(); This would output an error

    MyClass myObj = new MyClass(); // Create an object of MyClass
    myObj.myPublicMethod(); // Call the public method
  }
}

You have to use v-html directive for displaying html content inside a vue component

<div v-html="html content data property"></div>

update tablename set coldate=DATE_ADD(coldate, INTERVAL 2 DAY)

To avoid the error, use extract string:

<string name="travels_tours_pvt_ltd"><![CDATA[Travels & Tours (Pvt) Ltd.]]></string>

Use File.ReadAllText and File.WriteAllText.

MSDN example excerpt:

// Create a file to write to.
string createText = "Hello and Welcome" + Environment.NewLine;
File.WriteAllText(path, createText);

...

// Open the file to read from.
string readText = File.ReadAllText(path);

Version Code - It's a positive integer that's used for comparison with other version codes. It's not shown to the user, it's just for record-keeping in a way. You can set it to any integer you like but it's suggested that you linearly increment it for successive versions.

Version Name - This is the version string seen by the user. It isn't used for internal comparisons or anything, it's just for users to see.

For example: Say you release an app, its initial versionCode could be 1 and versionName could also be 1. Once you make some small changes to the app and want to publish an update, you would set versionName to "1.1" (since the changes aren't major) while logically your versionCode should be 2 (regardless of size of changes).

Say in another condition you release a completely revamped version of your app, you could set versionCode and versionName to "2".

Hope that helps.

The docs indicate that numpy.correlate is not what you are looking for:

numpy.correlate(a, v, mode='valid', old_behavior=False)[source]
  Cross-correlation of two 1-dimensional sequences.
  This function computes the correlation as generally defined in signal processing texts:
     z[k] = sum_n a[n] * conj(v[n+k])
  with a and v sequences being zero-padded where necessary and conj being the conjugate.

Instead, as the other comments suggested, you are looking for a Pearson correlation coefficient. To do this with scipy try:

from scipy.stats.stats import pearsonr   
a = [1,4,6]
b = [1,2,3]   
print pearsonr(a,b)

This gives

(0.99339926779878274, 0.073186395040328034)

You can also use numpy.corrcoef:

import numpy
print numpy.corrcoef(a,b)

This gives:

[[ 1.          0.99339927]
 [ 0.99339927  1.        ]]

It depends on what function you want to run. If you need something done on server side, like querying a database or setting something in the session or anything that can not be done on client side, you need AJAX, else you can do it on client-side with JavaScript. Don't make the server work when you can do what you need to do on client side.

jQuery provides an easy way to do ajax : http://api.jquery.com/jQuery.ajax/

If you want to stay as close as possible to the brace-expression syntax, try out the range function from bash-tricks' range.bash.

For example, all of the following will do the exact same thing as echo {1..10}:

source range.bash
one=1
ten=10

range {$one..$ten}
range $one $ten
range {1..$ten}
range {1..10}

It tries to support the native bash syntax with as few "gotchas" as possible: not only are variables supported, but the often-undesirable behavior of invalid ranges being supplied as strings (e.g. for i in {1..a}; do echo $i; done) is prevented as well.

The other answers will work in most cases, but they all have at least one of the following drawbacks:

• Many of them use subshells, which can harm performance and may not be possible on some systems.
• Many of them rely on external programs. Even seq is a binary which must be installed to be used, must be loaded by bash, and must contain the program you expect, for it to work in this case. Ubiquitous or not, that's a lot more to rely on than just the Bash language itself.
• Solutions that do use only native Bash functionality, like @ephemient's, will not work on alphabetic ranges, like {a..z}; brace expansion will. The question was about ranges of numbers, though, so this is a quibble.
• Most of them aren't visually similar to the {1..10} brace-expanded range syntax, so programs that use both may be a tiny bit harder to read.
• @bobbogo's answer uses some of the familiar syntax, but does something unexpected if the $END variable is not a valid range "bookend" for the other side of the range. If END=a, for example, an error will not occur and the verbatim value {1..a} will be echoed. This is the default behavior of Bash, as well--it is just often unexpected.

IsEmpty() would be the quickest way to check for that.

IsNull() would seem like a similar solution, but keep in mind Null has to be assigned to the cell; it's not inherently created in the cell.

Also, you can check the cell by:

count()

counta()

Len(range("BCell").Value) = 0

string folderPath = "";
FolderBrowserDialog folderBrowserDialog1 = new FolderBrowserDialog();
if (folderBrowserDialog1.ShowDialog() == DialogResult.OK) {
    folderPath = folderBrowserDialog1.SelectedPath ;
}

This code is correct but if you entered a lot of space (' ') instead of null or empty string return false.

To correct this use regular expresion (this code below check if the variable is null or empty or blank the same as org.apache.commons.lang.StringUtils.isNotBlank) :

<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn" %>
        <c:if test="${not empty description}">
            <c:set var="description" value="${fn:replace(description, ' ', '')}" />
            <c:if test="${not empty description}">
                  The description is not blank.
            </c:if>

I was getting this same error on my DigitalOcean Ubuntu server.

I tried changing the max_allowed_packet and the wait_timeout settings but neither of them fixed it.

It turns out that my server was out of RAM. I added a 1GB swap file and that fixed my problem.

Check your memory with free -h to see if that's what's causing it.

You can easily pick image from asset without UIImage(named: "green-square-Retina").

Instead use the image object directly from bundle.
Start typing the image name and you will get suggestions with actual image from bundle. It is advisable practice and less prone to error.

See this Stackoverflow answer for reference.

If you want to use the font to draw with graphics2d or similar, this works:

InputStream stream = ClassLoader.getSystemClassLoader().getResourceAsStream("roboto-bold.ttf")
Font font = Font.createFont(Font.TRUETYPE_FONT, stream).deriveFont(48f)

s =  "123,456.908"
print float(s.replace(',', ''))

Yet another Swift solution

func topController() -> UIViewController? {

    // recursive follow
    func follow(from:UIViewController?) -> UIViewController? {
        if let to = (from as? UITabBarController)?.selectedViewController {
            return follow(to)
        } else if let to = (from as? UINavigationController)?.visibleViewController {
            return follow(to)
        } else if let to = from?.presentedViewController {
            return follow(to)
        }
        return from
    }

    let root = UIApplication.sharedApplication().keyWindow?.rootViewController

    return follow(root)

}

As an option you can use com.fasterxml.jackson.databind.ObjectMapper to initialize a child class from parent

public class A {
    int x;
    int y;
}

public class B extends A {
    int z;
}

ObjectMapper MAPPER = new ObjectMapper(); //it's configurable
MAPPER.configure( DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false );
MAPPER.configure( SerializationFeature.FAIL_ON_EMPTY_BEANS, false );

//Then wherever you need to initialize child from parent:
A parent = new A(x, y);
B child = MAPPER.convertValue( parent, B.class);
child.setZ(z);

You can still use any lombok annotations on A and B if you need.

Given just the pointer, you can't. You'll have to keep hold of the length you passed to new[] or, better, use std::vector to both keep track of the length, and release the memory when you've finished with it.

_{Note: this answer only addresses C++, not C.}

This version should be linear in length of the string, and should be fine as long as the sequences aren't too repetitive (in which case you can replace the recursion with a while loop).

def find_all(st, substr, start_pos=0, accum=[]):
    ix = st.find(substr, start_pos)
    if ix == -1:
        return accum
    return find_all(st, substr, start_pos=ix + 1, accum=accum + [ix])

bstpierre's list comprehension is a good solution for short sequences, but looks to have quadratic complexity and never finished on a long text I was using.

findall_lc = lambda txt, substr: [n for n in xrange(len(txt))
                                   if txt.find(substr, n) == n]

For a random string of non-trivial length, the two functions give the same result:

import random, string; random.seed(0)
s = ''.join([random.choice(string.ascii_lowercase) for _ in range(100000)])

>>> find_all(s, 'th') == findall_lc(s, 'th')
True
>>> findall_lc(s, 'th')[:4]
[564, 818, 1872, 2470]

But the quadratic version is about 300 times slower

%timeit find_all(s, 'th')
1000 loops, best of 3: 282 µs per loop

%timeit findall_lc(s, 'th')    
10 loops, best of 3: 92.3 ms per loop

Apter tried to change itms-services://?action=download-manifest&url=http://.... to itms-services://?action=download-manifest&url=https://..... It also cannot worked. The alert is cannot connect to my domain. I find out that also need update the webpage too.

The issue isn’t with the main URL being HTTPS but some of the HTML code in a link within the page. You’ll need your developers to update the webpage. I also noticed there isn’t a valid SSL certificate on your staging domain so you’ll need to get one installed or use Dropbox and here is the link maybe helpful for you

You need to delete your old db folder and recreate new one. It will resolve your issue.

Thus, only alphanumerics, the special characters $-_.+!*'(), and reserved characters used for their reserved purposes may be used unencoded within a URL.

Note that if you want to scroll an element instead of the full window, elements don't have the scrollTo and scrollBy methods. You should:

var el = document.getElementById("myel"); // Or whatever method to get the element

// To set the scroll
el.scrollTop = 0;
el.scrollLeft = 0;

// To increment the scroll
el.scrollTop += 100;
el.scrollLeft += 100;

You can also mimic the window.scrollTo and window.scrollBy functions to all the existant HTML elements in the webpage on browsers that don't support it natively:

Object.defineProperty(HTMLElement.prototype, "scrollTo", {
    value: function(x, y) {
        el.scrollTop = y;
        el.scrollLeft = x;
    },
    enumerable: false
});

Object.defineProperty(HTMLElement.prototype, "scrollBy", {
    value: function(x, y) {
        el.scrollTop += y;
        el.scrollLeft += x;
    },
    enumerable: false
});

so you can do:

var el = document.getElementById("myel"); // Or whatever method to get the element, again

// To set the scroll
el.scrollTo(0, 0);

// To increment the scroll
el.scrollBy(100, 100);

NOTE: Object.defineProperty is encouraged, as directly adding properties to the prototype is a breaking bad habit (When you see it :-).

If using Suexec, ensure that the script and its directory are owned by the same user you specified in suexec.

In addition, ensure that the user running the cgi script has permissions execute permissions to the file AND the program specified in the shebang.

For example if my cgi script starts with

#! /usr/bin/cgirunner

Then the user needs permissions to execute /usr/bin/cgirunner.

Thanks Chad! To show all the errors associated with the key, here's what I came up with. For some reason the base Html.ValidationMessage helper only shows the first error associated with the key.

    <%= Html.ShowAllErrors(mykey) %>

HtmlHelper:

    public static String ShowAllErrors(this HtmlHelper helper, String key) {
        StringBuilder sb = new StringBuilder();
        if (helper.ViewData.ModelState[key] != null) {
            foreach (var e in helper.ViewData.ModelState[key].Errors) {
                TagBuilder div = new TagBuilder("div");
                div.MergeAttribute("class", "field-validation-error");
                div.SetInnerText(e.ErrorMessage);
                sb.Append(div.ToString());
            }
        }
        return sb.ToString();
    }

• getParameter() returns http request parameters. Those passed from the client to the server. For example http://example.com/servlet?parameter=1. Can only return String

• getAttribute() is for server-side usage only - you fill the request with attributes that you can use within the same request. For example - you set an attribute in a servlet, and read it from a JSP. Can be used for any object, not just string.

Adding a summary answer as the accepted one is quite long. The terms "row" and "column" are used in the context of CQL, not how Cassandra is actually implemented.

• A primary key uniquely identifies a row.
• A composite key is a key formed from multiple columns.
• A partition key is the primary lookup to find a set of rows, i.e. a partition.
• A clustering key is the part of the primary key that isn't the partition key (and defines the ordering within a partition).

Examples:

• PRIMARY KEY (a): The partition key is a.
• PRIMARY KEY (a, b): The partition key is a, the clustering key is b.
• PRIMARY KEY ((a, b)): The composite partition key is (a, b).
• PRIMARY KEY (a, b, c): The partition key is a, the composite clustering key is (b, c).
• PRIMARY KEY ((a, b), c): The composite partition key is (a, b), the clustering key is c.
• PRIMARY KEY ((a, b), c, d): The composite partition key is (a, b), the composite clustering key is (c, d).

Just for documentation, sometimes you need to run the script as sudo:

sudo Rscript path/to/your/file.R

Both i++ and ++i are short-hand for i = i + 1.

In addition to changing the value of i, they also return the value of i, either before adding one (i++) or after adding one (++i).

In a loop the third component is a piece of code that is executed after each iteration.

for (int i=0; i<10; i++)

The value of that part is not used, so the above is just the same as

for(int i=0; i<10; i = i+1)

or

for(int i=0; i<10; ++i)

Where it makes a difference (between i++ and ++i )is in these cases

while(i++ < 10)

for (int i=0; i++ < 10; )

The best solution I've found for this is to contain them in a parent div, and give that div a font-size of 0.

# To support matches from the beginning, not any matches:

items = ['a', 'ab', 'abc', 'bac']
prefix = 'ab'

filter(lambda x: x.startswith(prefix), items)

This does what you want:

public static void main (String[] args) {
    String a = "\\joe\\jill\\";
    String b = a.replaceAll("\\\\$", "").replaceAll("^\\\\", "");
    System.out.println(b);
}

The $ is used to remove the sequence in the end of string. The ^ is used to remove in the beggining.

As an alternative, you can use the syntax:

String b = a.replaceAll("\\\\$|^\\\\", "");

The | means "or".

In case you want to trim other chars, just adapt the regex:

String b = a.replaceAll("y$|^x", ""); // will remove all the y from the end and x from the beggining

Better example is here

 try {
   myDB = this.openOrCreateDatabase("DatabaseName", MODE_PRIVATE, null);

   /* Create a Table in the Database. */
   myDB.execSQL("CREATE TABLE IF NOT EXISTS "
     + TableName
     + " (Field1 VARCHAR, Field2 INT(3));");

   /* Insert data to a Table*/
   myDB.execSQL("INSERT INTO "
     + TableName
     + " (Field1, Field2)"
     + " VALUES ('Saranga', 22);");

   /*retrieve data from database */
   Cursor c = myDB.rawQuery("SELECT * FROM " + TableName , null);

   int Column1 = c.getColumnIndex("Field1");
   int Column2 = c.getColumnIndex("Field2");

   // Check if our result was valid.
   c.moveToFirst();
   if (c != null) {
    // Loop through all Results
    do {
     String Name = c.getString(Column1);
     int Age = c.getInt(Column2);
     Data =Data +Name+"/"+Age+"\n";
    }while(c.moveToNext());
   }

Yes, struct is exactly like class except the default accessibility is public for struct (while it's private for class).

Using preprocessor directives is considered evil most of the time. Ideally you want to avoid them like the Pest. Remember that making the compiler understand your code is easy, allowing other programmers to understand your code is much harder. A few dozen cases like this here and there makes it very hard to read for yourself later or for others right now.

One way might be to put your parameters together into some sort of argument class. You could then use only a subset of the variables (equivalent to your assigning 0 really) or having different specializations of that argument class for each platform. This might however not be worth it, you need to analyze whether it would fit.

If you can read impossible templates, you might find advanced tips in the "Exceptional C++" book. If the people who would read your code could get their skillset to encompass the crazy stuff taught in that book, then you would have beautiful code which can also be easily read. The compiler would also be well aware of what you are doing (instead of hiding everything by preprocessing)

On Chrome and Firefox 32+, navigator.languages contains an array of locales in order of user preference, and is more accurate than navigator.language, however to make it backwards-compatible (Tested Chrome / IE / Firefox / Safari), then use this:

function getLang()
{
 if (navigator.languages != undefined) 
 return navigator.languages[0]; 
 else 
 return navigator.language;
}

myWindow.Activate();

Attempts to bring the window to the foreground and activates it.

That should do the trick, unless I misunderstood and you want Always on Top behavior. In that case you want:

myWindow.TopMost = true;

If above solutions did not work for you then you may have doing something as following ..

1) installing the app from Appstore.
2) updating it with sign APK with same package name updated version.

So basically there are two kinds if APK's.

1) you uploaded on playstore known as original APK.
2) download from playstore known as derived APK.

In this case basically you are downloading derived apk and updating it with original APK.

For let it work fine uploaded new signed released APK in the internal test mode on the Google Play Store and download the derived APK to check the update scenario.

In direct response to the Question Title...

dplyr definitely does things that data.table can not.

Your point #3

dplyr abstracts (or will) potential DB interactions

is a direct answer to your own question but isn't elevated to a high enough level. dplyr is truly an extendable front-end to multiple data storage mechanisms where as data.table is an extension to a single one.

Look at dplyr as a back-end agnostic interface, with all of the targets using the same grammer, where you can extend the targets and handlers at will. data.table is, from the dplyr perspective, one of those targets.

You will never (I hope) see a day that data.table attempts to translate your queries to create SQL statements that operate with on-disk or networked data stores.

dplyr can possibly do things data.table will not or might not do as well.

Based on the design of working in-memory, data.table could have a much more difficult time extending itself into parallel processing of queries than dplyr.

In response to the in-body questions...

Usage

Are there analytical tasks that are a lot easier to code with one or the other package for people familiar with the packages (i.e. some combination of keystrokes required vs. required level of esotericism, where less of each is a good thing).

This may seem like a punt but the real answer is no. People familiar with tools seem to use the either the one most familiar to them or the one that is actually the right one for the job at hand. With that being said, sometimes you want to present a particular readability, sometimes a level of performance, and when you have need for a high enough level of both you may just need another tool to go along with what you already have to make clearer abstractions.

Performance

Are there analytical tasks that are performed substantially (i.e. more than 2x) more efficiently in one package vs. another.

Again, no. data.table excels at being efficient in everything it does where dplyr gets the burden of being limited in some respects to the underlying data store and registered handlers.

This means when you run into a performance issue with data.table you can be pretty sure it is in your query function and if it is actually a bottleneck with data.table then you've won yourself the joy of filing a report. This is also true when dplyr is using data.table as the back-end; you may see some overhead from dplyr but odds are it is your query.

When dplyr has performance issues with back-ends you can get around them by registering a function for hybrid evaluation or (in the case of databases) manipulating the generated query prior to execution.

Also see the accepted answer to when is plyr better than data.table?

I don't understand why the other friends tell you use HH, But after I test so many time, The correct 24 hour format is :

hh

.

I see it from : http://www.malot.fr/bootstrap-datetimepicker/

I don't know why they don't use the common type HH for 24 hour.....

I hope anyone could tell me if I'm wrong.....

Ruby 2.1.0 introduced a to_h method on Array that does what you require if your original array consists of arrays of key-value pairs: http://www.ruby-doc.org/core-2.1.0/Array.html#method-i-to_h.

[[:foo, :bar], [1, 2]].to_h
# => {:foo => :bar, 1 => 2}

Also do note when specifying DATETIME as DATETIME(3) or like on MySQL 5.7.x, you also have to add the same value for CURRENT_TIMESTAMP(3). If not it will keep throwing 'Invalid default value'.

Open tmux configuration file with the following command:

vim ~/.tmux.conf

In the configuration file add the following line:

set -g history-limit 5000

Log out and log in again, start a new tmux windows and your limit is 5000 now.

All solution mentioned above using that code which are deprecated now!Here is the new solution

1. Add implementation 'com.google.android.gms:play-services-places:15.0.1' dependency in your gradle file

2. Add network permission in your manifest file:

<uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

3. Now use this code to get current location

     FusedLocationProviderClient mFusedLocationClient = LocationServices.getFusedLocationProviderClient(this);
   
     mFusedLocationClient.getLastLocation().addOnSuccessListener(new OnSuccessListener<Location>() {
                   @Override
                   public void onSuccess(Location location) {
                       // GPS location can be null if GPS is switched off
                           currentLat = location.getLatitude();
                           currentLong = location.getLongitude();
                           Toast.makeText(HomeNavigationBarActivtiy.this, "lat " + location.getLatitude() + "\nlong " + location.getLongitude(), Toast.LENGTH_SHORT).show();
                   }
               })
               .addOnFailureListener(new OnFailureListener() {
                   @Override
                   public void onFailure(@NonNull Exception e) {
                       e.printStackTrace();
                   }
               });
   

Add your Maven bin path to the System variable as given below

Go to the

> Enviornment Variables > set Path=D:\apache-maven-3.2.1\bin

or if path is already set than append the path with ";"

restart command and try

Current Example:

You need to define border-width:1px

Your code should read:

$(this).css({"border-color": "#C1E0FF", 
             "border-width":"1px", 
             "border-style":"solid"});

Suggested Example:

You should ideally use a class and addClass/removeClass

$(this).addClass('borderClass'); $(this).removeClass('borderClass');

and in your CSS:

.borderClass{
  border-color: #C1E0FF;
  border-width:1px;
  border-style: solid;
  /** OR USE INLINE
  border: 1px solid #C1E0FF;
  **/
}

jsfiddle working example: http://jsfiddle.net/gorelative/tVbvF/\

jsfiddle with animate: http://jsfiddle.net/gorelative/j9Xxa/ This just gives you an example of how it could work, you should get the idea.. There are better ways of doing this most likely.. like using a toggle()

I think this first failed because you are ordering value which is null. If Delivery is a foreign key associated table then you should include this table first, example below:

var itemList = from t in ctn.Items.Include(x=>x.Delivery)
                    where !t.Items && t.DeliverySelection
                    orderby t.Delivery.SubmissionDate descending
                    select t;

Not Ideal, but try this...

Change the usercontrol to Component class (In the code editor), build the solution and remove all the code with errors (Related to usercontrols but not available in components so the debugger complains about it)

Change the usercontrol back to usercontrol class...

Now it recognises the name and parent property but shows the component as non-visual as it is no longer designable.

Follow these steps if you're on openSuse or SUSE.

Install php7 if it's not already installed.

zypper in php7

If you have php7 installed, update it with:

zypper update php7

Install php7-sockets

I think todays, it is better to use, but only with C++17.

#include <type_traits>

template <typename T>
void foo() {
    if constexpr (std::is_same_v<T, animal>) {
        // use type specific operations... 
    } 
}

If you use some type specific operations in if expression body without constexpr, this code will not compile.

You are using <input name='C[]' in your HTML. This creates an array in PHP when the form is sent.

You are using echo $_POST['C']; to echo that array - this will not work, but instead emit that notice and the word "Array".

Depending on what you did with the rest of the code, you should probably use echo $_POST['C'][0];

in c#.net

this.WindowState = FormWindowState.Minimized

Object.keys(myObj).length === 0;

As there is need to just check if Object is empty it will be better to directly call a native method Object.keys(myObj).length which returns the array of keys by internally iterating with for..in loop.As Object.hasOwnProperty returns a boolean result based on the property present in an object which itself iterates with for..in loop and will have time complexity O(N2).

On the other hand calling a UDF which itself has above two implementations or other will work fine for small object but will block the code which will have severe impact on overall perormance if Object size is large unless nothing else is waiting in the event loop.

This is more a workaround than a real solution. You can create a new object test_data with another column name:

left_join("names<-"(test_data, "name"), kantrowitz, by = "name")

     name gender
1    john      M
2    bill either
3 madison      M
4    abby either
5     zzz   <NA>

Please install at ubuntu openjdk-7-jdk

sudo apt-get install openjdk-7-jdk

on Windows try find find openjdk

If the object you are trying to cast from or to has properties that are also user-defined classes, and you don't want to go through reflection, you can use this.

<?php
declare(strict_types=1);
namespace Your\Namespace\Here
{
  use Zend\Logger; // or your logging mechanism of choice
  final class OopFunctions
  {
    /**
     * @param object $from
     * @param object $to
     * @param Logger $logger
     *
     * @return object
     */
     static function Cast($from, $to, $logger)
    {
      $logger->debug($from);
      $fromSerialized = serialize($from);
      $fromName = get_class($from);
      $toName = get_class($to);
      $toSerialized = str_replace($fromName, $toName, $fromSerialized);
      $toSerialized = preg_replace("/O:\d*:\"([^\"]*)/", "O:" . strlen($toName) . ":\"$1", $toSerialized);
      $toSerialized = preg_replace_callback(
        "/s:\d*:\"[^\"]*\"/", 
        function ($matches)
        {
          $arr = explode(":", $matches[0]);
          $arr[1] = mb_strlen($arr[2]) - 2;
          return implode(":", $arr);
        }, 
        $toSerialized
      );
      $to = unserialize($toSerialized);
      $logger->debug($to);
      return $to;
    }
  }
}

The difference you could see if you had another couple of functions:

var h = document.getElementById('a');
h.onclick = doThing_1;
h.onclick = doThing_2;

h.addEventListener('click', doThing_3);
h.addEventListener('click', doThing_4);

Functions 2, 3 and 4 work, but 1 does not. This is because addEventListener does not overwrite existing event handlers, whereas onclick overrides any existing onclick = fn event handlers.

The other significant difference, of course, is that onclick will always work, whereas addEventListener does not work in Internet Explorer before version 9. You can use the analogous attachEvent (which has slightly different syntax) in IE <9.

If you get a python error like this:

AttributeError: 'str' object has no attribute 'some_method'

You probably poisoned your object accidentally by overwriting your object with a string.

How to reproduce this error in python with a few lines of code:

#!/usr/bin/env python
import json
def foobar(json):
    msg = json.loads(json)

foobar('{"batman": "yes"}')

Run it, which prints:

AttributeError: 'str' object has no attribute 'loads'

But change the name of the variablename, and it works fine:

#!/usr/bin/env python
import json
def foobar(jsonstring):
    msg = json.loads(jsonstring)

foobar('{"batman": "yes"}')

This error is caused when you tried to run a method within a string. String has a few methods, but not the one you are invoking. So stop trying to invoke a method which String does not define and start looking for where you poisoned your object.

I would like to shared with you my implementation for find first responder in anywhere of UIView. I hope it helps and sorry for my english. Thanks

+ (UIView *) findFirstResponder:(UIView *) _view {

    UIView *retorno;

    for (id subView in _view.subviews) {

        if ([subView isFirstResponder])
        return subView;

        if ([subView isKindOfClass:[UIView class]]) {
            UIView *v = subView;

            if ([v.subviews count] > 0) {
                retorno = [self findFirstResponder:v];
                if ([retorno isFirstResponder]) {
                    return retorno;
                }
            }
        }
    }

    return retorno;
}

Better solution: use Javascript's native Array.from() and to convert HTMLCollection object to an array, after which you can use standard array functions.

var t = document.getElementById('mytab1');
if(t) {
    Array.from(t.rows).forEach((tr, row_ind) => {
        Array.from(tr.cells).forEach((cell, col_ind) => {
            console.log('Value at row/col [' + row_ind + ',' + col_ind + '] = ' + cell.textContent);
        });
    });
}

You could also reference tr.rowIndex and cell.colIndex instead of using row_ind and col_ind.

I much prefer this approach over the top 2 highest-voted answers because it does not clutter your code with global variables i, j, row and col, and therefore it delivers clean, modular code that will not have any side effects (or raise lint / compiler warnings)... without other libraries (e.g. jquery).

If you require this to run in an old version (pre-ES2015) of Javascript, Array.from can be polyfilled.

I had this issue too and tried different memory expansion techniques I found on the web but had more troubles with it. I resolved to using the MySQL console source command, and of course you don't have to worry about phpMyAdmin or PHP maximum execution time and limits.

Syntax: source c:\path\to\dump_file.sql

Note: It's better to specify an absolute path to the dump file since the mysql working directory might not be known.

With ES6 you can now do it like this

Use a GET request to download the image and save it to a web accessible directory on your server.

As you are using PHP, you can use curl to download files from the other server.

In ExtJs, you can use

xtype: 'image'

to render a image.

Here is a fiddle showing rendering of binary data with extjs.

atob -- > converts ascii to binary

btoa -- > converts binary to ascii

Ext.application({
    name: 'Fiddle',

    launch: function () {
        var srcBase64 = "data:image/jpeg;base64," + btoa(atob("iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAADUlEQVR42mP8H8hYDwAFegHS8+X7mgAAAABJRU5ErkJggg=="));

        Ext.create("Ext.panel.Panel", {
            title: "Test",
            renderTo: Ext.getBody(),
            height: 400,
            items: [{
                xtype: 'image',
                width: 100,
                height: 100,
                src: srcBase64
            }]
        })
    }
});

https://fiddle.sencha.com/#view/editor&fiddle/28h0

var myobject = new MyClass1("5678999", "text");
var dto = { MyClass1: myobject };
console.log(JSON.stringify(dto));

EDIT:

JSON.stringify will stringify all 'properties' of your class. If you want to persist only some of them, you can specify them individually like this:

var dto = { MyClass1: {
    property1: myobject.property1,
    property2: myobject.property2
}};

document.getElementsByName("name") will get several elements called by same name . document.getElementsByName("name")[Number] will get one of them. document.getElementsByName("name")[Number].value will get the value of paticular element.

The key of this question is this:
The name of elements is not unique, it is usually used for several input elements in the form.
On the other hand, the id of the element is unique, which is the only definition for a particular element in a html file.

please remove " runat="server" " from "form" tag then it will definetly works.

The return type depends on the server, sometimes the response is indeed a JSON array but sent as text/plain

Setting the accept headers in the request should get the correct type:

client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); 

which can then be serialized to a JSON list or array. Thanks for the comment from @svick which made me curious that it should work.

The Exception I got without configuring the accept headers was System.Net.Http.UnsupportedMediaTypeException.

Following code is cleaner and should work (untested, but works in my case):

    var client = new HttpClient();
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
    var response = await client.GetAsync("http://api.usa.gov/jobs/search.json?query=nursing+jobs");
    var model = await response.Content.ReadAsAsync<List<Job>>();

Using a for loop, how do I access the loop index, from 1 to 5 in this case?

Use enumerate to get the index with the element as you iterate:

for index, item in enumerate(items):
    print(index, item)

And note that Python's indexes start at zero, so you would get 0 to 4 with the above. If you want the count, 1 to 5, do this:

for count, item in enumerate(items, start=1):
    print(count, item)

Unidiomatic control flow

What you are asking for is the Pythonic equivalent of the following, which is the algorithm most programmers of lower-level languages would use:

index = 0            # Python's indexing starts at zero
for item in items:   # Python's for loops are a "for each" loop 
    print(index, item)
    index += 1

Or in languages that do not have a for-each loop:

index = 0
while index < len(items):
    print(index, items[index])
    index += 1

or sometimes more commonly (but unidiomatically) found in Python:

for index in range(len(items)):
    print(index, items[index])

Use the Enumerate Function

Python's enumerate function reduces the visual clutter by hiding the accounting for the indexes, and encapsulating the iterable into another iterable (an enumerate object) that yields a two-item tuple of the index and the item that the original iterable would provide. That looks like this:

for index, item in enumerate(items, start=0):   # default is zero
    print(index, item)

This code sample is fairly well the canonical example of the difference between code that is idiomatic of Python and code that is not. Idiomatic code is sophisticated (but not complicated) Python, written in the way that it was intended to be used. Idiomatic code is expected by the designers of the language, which means that usually this code is not just more readable, but also more efficient.

Getting a count

Even if you don't need indexes as you go, but you need a count of the iterations (sometimes desirable) you can start with 1 and the final number will be your count.

for count, item in enumerate(items, start=1):   # default is zero
    print(item)

print('there were {0} items printed'.format(count))

The count seems to be more what you intend to ask for (as opposed to index) when you said you wanted from 1 to 5.

Breaking it down - a step by step explanation

To break these examples down, say we have a list of items that we want to iterate over with an index:

items = ['a', 'b', 'c', 'd', 'e']

Now we pass this iterable to enumerate, creating an enumerate object:

enumerate_object = enumerate(items) # the enumerate object

We can pull the first item out of this iterable that we would get in a loop with the next function:

iteration = next(enumerate_object) # first iteration from enumerate
print(iteration)

And we see we get a tuple of 0, the first index, and 'a', the first item:

(0, 'a')

we can use what is referred to as "sequence unpacking" to extract the elements from this two-tuple:

index, item = iteration
#   0,  'a' = (0, 'a') # essentially this.

and when we inspect index, we find it refers to the first index, 0, and item refers to the first item, 'a'.

>>> print(index)
0
>>> print(item)
a

Conclusion

• Python indexes start at zero
• To get these indexes from an iterable as you iterate over it, use the enumerate function
• Using enumerate in the idiomatic way (along with tuple unpacking) creates code that is more readable and maintainable:

So do this:

for index, item in enumerate(items, start=0):   # Python indexes start at zero
    print(index, item)

If you have format dd-mm-yyyy then in PHP it won't work as expected. In PHP document they have below guideline.

Dates in the m/d/y or d-m-y formats are disambiguated by looking at the separator between the various components: if the separator is a slash (/), then the American m/d/y is assumed; whereas if the separator is a dash (-) or a dot (.), then the European d-m-y format is assumed.

So, you just can't use as you wish. When your try to use dd/mm/yyyy format with this then it will remove FALSE. You can tweak with the following.

$date = "23/02/2013";
$timestamp = strtotime($date);
if ($timestamp === FALSE) {
  $timestamp = strtotime(str_replace('/', '-', $date));
}
echo $timestamp; // prints 1361577600

localStorage is something that is kept on the client side. There is no data transmitted to the server side.

You can only get the data with JavaScript and you can send it to the server side with Ajax.

I Have Use This Idea For Finding If The No. Is Prime or Not:

#include <conio.h> 
#include <iostream>
using namespace std;
int main() {
  int x, a;
  cout << "Enter The No. :";
  cin >> x;
  int prime(unsigned int);
  a = prime(x);
  if (a == 1)
    cout << "It Is A Prime No." << endl;
  else
  if (a == 0)
    cout << "It Is Composite No." << endl;
  getch();
}

int prime(unsigned int x) {
  if (x == 1) {
    cout << "It Is Neither Prime Nor Composite";
    return 2;
  }
  if (x == 2 || x == 3 || x == 5 || x == 7)
    return 1;
  if (x % 2 != 0 && x % 3 != 0 && x % 5 != 0 && x % 7 != 0)
    return 1;
  else
    return 0;
}

I encountered a similar problem when I was using the below to obtain connection factory ConnectionFactory factory = new
ActiveMQConnectionFactory("admin","admin","tcp://:61616");

Its resolved when I changed it to the below

ConnectionFactory factory = new ActiveMQConnectionFactory("tcp://:61616");

The below then showed that my Q size was increasing.. http://:8161/admin/queues.jsp

Two ways to run eclipse in clean mode.

1 ) In Eclipse.ini file

• Open the eclipse.ini file located in the Eclipse installation directory.
  
• Add -clean first line in the file.
  
• Save the file.
  
• Restart Eclipse.

2 ) From Command prompt (cmd/command)

• Go to folder where Eclipse installed.
  
• Take the path of Eclipse
  
• C:..\eclipse\eclipse.exe -clean
  
• press enter button
  

>>> d = {}
>>> D = set()
>>> type(d)
<type 'dict'>
>>> type(D)
<type 'set'>

What you've made is a dictionary and not a Set.

The update method in dictionary is used to update the new dictionary from a previous one, like so,

>>> abc = {1: 2}
>>> d.update(abc)
>>> d
{1: 2}

Whereas in sets, it is used to add elements to the set.

>>> D.update([1, 2])
>>> D
set([1, 2])

Your code looks syntactically correct, but I think your property doesn't exist to create the URL.

I just tested it, and it works fine for me.

Try using category.idCategory instead of category.id, for example…

  <tr th:each="category : ${categories}">
    <td th:text="${category.idCategory}"></td>
    <td th:text="${category.name}"></td>
    <td>
      <a th:href="@{'/category/edit/' + ${category.idCategory}}">view</a>

  </tr>

Try this: for the previous view use this:

navigationController?.popViewController(animated: true)  

pop to root use this code:

navigationController?.popToRootViewController(animated: true)

We should also consider that the SVM system can be applied directly to non-metric spaces, such as the set of labeled graphs or strings. In fact, the internal kernel function can be generalized properly to virtually any kind of input, provided that the positive definiteness requirement of the kernel is satisfied. On the other hand, to be able to use an ANN on a set of labeled graphs, explicit embedding procedures must be considered.

I realize this may be a bit late, but I stumbled upon this and was wondering how to handle situations with multiple identical values, but different keys (as per bigbearzhu's comment).

So I modified Stephan Muller's answer slightly:

A datalist with non-unique values:

<input list="answers" name="answer" id="answerInput">
<datalist id="answers">
  <option value="42">The answer</option>
  <option value="43">The answer</option>
  <option value="44">Another Answer</option>
</datalist>
<input type="hidden" name="answer" id="answerInput-hidden">

When the user selects an option, the browser replaces input.value with the value of the datalist option instead of the innerText.

The following code then checks for an option with that value, pushes that into the hidden field and replaces the input.value with the innerText.

document.querySelector('#answerInput').addEventListener('input', function(e) {
    var input = e.target,   
        list = input.getAttribute('list'),
        options = document.querySelectorAll('#' + list + ' option[value="'+input.value+'"]'),
        hiddenInput = document.getElementById(input.getAttribute('id') + '-hidden');

    if (options.length > 0) {
      hiddenInput.value = input.value;
      input.value = options[0].innerText;
      }

});

As a consequence the user sees whatever the option's innerText says, but the unique id from option.value is available upon form submit. Demo jsFiddle

Java doesn't use includes the way C does. Instead java uses a concept called the classpath, a list of resources containing java classes. The JVM can access any class on the classpath by name so if you can extend classes and refer to types simply by declaring them. The closes thing to an include statement java has is 'import'. Since classes are broken up into namespaces like foo.bar.Baz, if you're in the qux package and you want to use the Baz class without having to use its full name of foo.bar.Baz, then you need to use an import statement at the beginning of your java file like so: import foo.bar.Baz

Taken from the MySQL 8.0 Reference Manual:

• utf8mb4: A UTF-8 encoding of the Unicode character set using one to four bytes per character.

• utf8mb3: A UTF-8 encoding of the Unicode character set using one to three bytes per character.

In MySQL utf8 is currently an alias for utf8mb3 which is deprecated and will be removed in a future MySQL release. At that point utf8 will become a reference to utf8mb4.

So regardless of this alias, you can consciously set yourself an utf8mb4 encoding.

To complete the answer, I'd like to add the @WilliamEntriken's comment below (also taken from the manual):

To avoid ambiguity about the meaning of utf8, consider specifying utf8mb4 explicitly for character set references instead of utf8.

Here's a simplified function that will read in bytes and create a string. It assumes you probably already know what encoding the file is in (and otherwise defaults).

static final int BUFF_SIZE = 2048;
static final String DEFAULT_ENCODING = "utf-8";

public static String readFileToString(String filePath, String encoding) throws IOException {

    if (encoding == null || encoding.length() == 0)
        encoding = DEFAULT_ENCODING;

    StringBuffer content = new StringBuffer();

    FileInputStream fis = new FileInputStream(new File(filePath));
    byte[] buffer = new byte[BUFF_SIZE];

    int bytesRead = 0;
    while ((bytesRead = fis.read(buffer)) != -1)
        content.append(new String(buffer, 0, bytesRead, encoding));

    fis.close();        
    return content.toString();
}

You simply have to do:

INSERT INTO def (catid, title, page, publish) 
SELECT catid, title, 'page','yes' from `abc`

HigLabo.Mail is easy to use. Here is a sample usage:

using (Pop3Client cl = new Pop3Client()) 
{ 
    cl.UserName = "MyUserName"; 
    cl.Password = "MyPassword"; 
    cl.ServerName = "MyServer"; 
    cl.AuthenticateMode = Pop3AuthenticateMode.Pop; 
    cl.Ssl = false; 
    cl.Authenticate(); 
    ///Get first mail of my mailbox 
    Pop3Message mg = cl.GetMessage(1); 
    String MyText = mg.BodyText; 
    ///If the message have one attachment 
    Pop3Content ct = mg.Contents[0];         
    ///you can save it to local disk 
    ct.DecodeData("your file path"); 
} 

you can get it from https://github.com/higty/higlabo or Nuget [HigLabo]

You should use DecimalFormat("0.#")

For 4.3000

Double price = 4.3000;
DecimalFormat format = new DecimalFormat("0.#");
System.out.println(format.format(price));

output is:

4.3

In case of 5.000 we have

Double price = 5.000;
DecimalFormat format = new DecimalFormat("0.#");
System.out.println(format.format(price));

And the output is:

5

For the latest jupyter notebook, (version 5) you can go to the 'help' tab in the top of the notebook and then select the option 'edit keyboard shortcuts' and add in your own customized shortcut for the 'run all' function.

It is a common misconception that time (a measurable 4th dimension) is different over the world. Timestamp as a moment in time is unique. Date however is influenced how we "see" time but actually it is "time of day".

An example: two people look at the clock at the same moment. The timestamp is the same, right? But one of them is in London and sees 12:00 noon (GMT, timezone offset is 0), and the other is in Belgrade and sees 14:00 (CET, Central Europe, daylight saving now, offset is +2).

Their perception is different but the moment is the same.

You can find more details in this answer.

UPDATE

OK, it's not a duplicate of this question but it is pointless since you are confusing the terms "Timestamp = moment in time (objective)" and "Date[Time] = time of day (subjective)".

Let's look at your original question code broken down like this:

// Get the "original" value from database.
Timestamp momentFromDB = rs.getTimestamp("anytimestampcolumn");

// Turn it into a Joda DateTime with time zone.
DateTime dt = new DateTime(momentFromDB, DateTimeZone.forID("anytimezone"));

// And then turn it back into a timestamp but "with time zone".
Timestamp ts = new Timestamp(dt.getMillis());

I haven't run this code but I am certain it will print true and the same number of milliseconds each time:

System.out.println("momentFromDB == dt : " + (momentFromDB.getTime() == dt.getTimeInMillis());
System.out.println("momentFromDB == ts : " + (momentFromDB.getTime() == ts.getTime()));
System.out.println("dt == ts : " + (dt.getTimeInMillis() == ts.getTime()));

System.out.println("momentFromDB [ms] : " + momentFromDB.getTime());
System.out.println("ts [ms] : " + ts.getTime());
System.out.println("dt [ms] : " + dt.getTimeInMillis());

But as you said yourself printing them out as strings will result in "different" time because DateTime applies the time zone. That's why "time" is stored and transferred as Timestamp objects (which basically wraps a long) and displayed or entered as Date[Time].

In your own answer you are artificially adding an offset and creating a "wrong" time. If you use that timestamp to create another DateTime and print it out it will be offset twice.

// Turn it back into a Joda DateTime with time zone.
DateTime dt = new DateTime(ts, DateTimeZone.forID("anytimezone"));

P.S. If you have the time go through the very complex Joda Time source code to see how it holds the time (millis) and how it prints it.

        final String sydneyTime = sydneyFormatTZ.format(milleniumInLondon);

        // WHat do you think, will the test pass?
        assertThat(londonTime, equalTo(Y2K_LONDON));
        assertThat(newYorkTime, equalTo(Y2K_NEW_YORK));
        assertThat(sydneyTime, equalTo(Y2K_SYDNEY));

For anyone still wondering, a more complete answer is available at http://devio.wordpress.com/2009/10/19/get-absolut-url-of-asp-net-application/.

public string FullyQualifiedApplicationPath
{
    get
    {
        //Return variable declaration
        var appPath = string.Empty;

        //Getting the current context of HTTP request
        var context = HttpContext.Current;

        //Checking the current context content
        if (context != null)
        {
            //Formatting the fully qualified website url/name
            appPath = string.Format("{0}://{1}{2}{3}",
                                    context.Request.Url.Scheme,
                                    context.Request.Url.Host,
                                    context.Request.Url.Port == 80
                                        ? string.Empty
                                        : ":" + context.Request.Url.Port,
                                    context.Request.ApplicationPath);
        }

        if (!appPath.EndsWith("/"))
            appPath += "/";

        return appPath;
    }
}

Might not help you right now, but JDK 7 is intended to have glob and regex file name matching as part of "More NIO Features".

Pre C# 6.0 solution

You can use this to get a name of any provided member:

public static class MemberInfoGetting
{
    public static string GetMemberName<T>(Expression<Func<T>> memberExpression)
    {
        MemberExpression expressionBody = (MemberExpression)memberExpression.Body;
        return expressionBody.Member.Name;
    }
}

To get name of a variable:

string testVariable = "value";
string nameOfTestVariable = MemberInfoGetting.GetMemberName(() => testVariable);

To get name of a parameter:

public class TestClass
{
    public void TestMethod(string param1, string param2)
    {
        string nameOfParam1 = MemberInfoGetting.GetMemberName(() => param1);
    }
}

C# 6.0 and higher solution

You can use the nameof operator for parameters, variables and properties alike:

string testVariable = "value";
string nameOfTestVariable = nameof(testVariable);

In case is saves someone else 3 hours... my case was a bit different. My code used DevExpress v11.1 v11.1.4.0. I had it all referenced correctly in my code. But .net memory profiler installed DevExpress v11.1 v11.1.12.0 in the GAC. In fact it wasn't the components I referenced but the ones they referenced internally that failed. Try as I might, the GAC is always checked first. It compiled and ran fine but I couldn't view the win forms designer and the stack trace was no help at all. Finally uninstalled .net memory profiler and all was restored.

I prefer to solve this in the classic way, creating a new array of my desired data type:

List<MyNewType> newArray = new ArrayList<>();
myOldArray.forEach(info -> newArray.add(objectMapper.convertValue(info, MyNewType.class)));

I was facing the same issue, to solve it I have added the below entry in pom.xml and performed a maven update.

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
    <version>1.2</version>
</dependency>

You can use the following code snippet:

myTextBox.SelectionStart = myTextBox.Text.Length;
myTextBox.ScrollToCaret();

which will automatically scroll to the end.

you can do something like that:

where regexp_like(name, 'string$', 'i');

Even i do have core i5 machine and 4GB RAM, i do face the same issue. On clean and rebuild the project gradle build system downloads the files jar/lib fresh files from internet. You need to disable this option available in settings of your Android studio. This will re-use the cached lib/jar files. Also the speed of Android studio depends on speed of your hard disk also. Here is detailed blog-post on how to improve too slow Android studio.

Here's my simple solution to update the query params in the URL without refreshing the page. Make sure it works for your use case.

const query = { ...this.$route.query, someParam: 'some-value' };
this.$router.replace({ query });

here is my implementation

public static byte[] intToByteArray(int a) {
    return BigInteger.valueOf(a).toByteArray();
}

public static int byteArrayToInt(byte[] b) {
    return new BigInteger(b).intValue();
}

Working Query:

SELECT replace(col_name , ' ','') FROM table_name;

While this doesn't :

SELECT trim(col_name) FROM table_name;
