For anyone that finds this question looking for how to access custom properties in ASP.NET Core 2.1 - it's much easier: You'll have a UserManager, e.g. in _LoginPartial.cshtml, and then you can simply do (assuming "ScreenName" is a property that you have added to your own AppUser which inherits from IdentityUser):

@using Microsoft.AspNetCore.Identity

@using <namespaceWhereYouHaveYourAppUser>

@inject SignInManager<AppUser> SignInManager
@inject UserManager<AppUser> UserManager

@if (SignInManager.IsSignedIn(User)) {
    <form asp-area="Identity" asp-page="/Account/Logout" asp-route-returnUrl="@Url.Action("Index", "Home", new { area = "" })" 
          method="post" id="logoutForm" 
          class="form-inline my-2 my-lg-0">

        <ul class="nav navbar-nav ml-auto">
            <li class="nav-item">
                <a class="nav-link" asp-area="Identity" asp-page="/Account/Manage/Index" title="Manage">
                    Hello @((await UserManager.GetUserAsync(User)).ScreenName)!
                    <!-- Original code, shows Email-Address: @UserManager.GetUserName(User)! -->
                </a>
            </li>
            <li class="nav-item">
                <button type="submit" class="btn btn-link nav-item navbar-link nav-link">Logout</button>
            </li>
        </ul>

    </form>
} else {
    <ul class="navbar-nav ml-auto">
        <li class="nav-item"><a class="nav-link" asp-area="Identity" asp-page="/Account/Register">Register</a></li>
        <li class="nav-item"><a class="nav-link" asp-area="Identity" asp-page="/Account/Login">Login</a></li>
    </ul>
}

Not with an iterator.

For org.json.JSONArray, you can do:

for (int i = 0; i < arr.length(); i++) {
  arr.getJSONObject(i);
}

For javax.json.JsonArray, you can do:

for (int i = 0; i < arr.size(); i++) {
  arr.getJsonObject(i);
}

I normally do this in VB and its easier because Excel records macros in VB. So I normally go to Excel and save the macro I want to do.

So that's what I did now and I got this code:

Columns("E:E").ColumnWidth = 17.29;

Range("E3").Interior.Pattern = xlSolid;
Range("E3").Interior.PatternColorIndex = xlAutomatic;
Range("E3").Interior.Color = 65535;
Range("E3").Interior.TintAndShade = 0;
Range("E3").Interior.PatternTintAndShade = 0;

I think you can do something like this:

xlWorkSheet.Columns[5].ColumnWidth = 18;

For your last question what you need to do is loop trough the columns you want to set their width:

for (int i = 1; i <= 10; i++) // this will apply it from col 1 to 10
{
    xlWorkSheet.Columns[i].ColumnWidth = 18;
}

With Z I assume you mean Integers , i.e 3,-5,77 not 3.14, 4.02 etc.

A regular expression may help:

Pattern isInteger = Pattern.compile("\\d+");

Just Restart-Service hns can change the port occupier by Hyper-V. It might release the port you need.

the above query only works if we have created clients table with matching columns of the customer

INSERT INTO clients(c_id,name,address)SELECT c_id,name,address FROM customer

Another similar way to do it by css:

#img:hover {visibility:hidden}_x000D_
#thistext {font-size:22px;color:white }_x000D_
#thistext:hover {color:black;}_x000D_
#hoverme {width:50px;height:50px;}_x000D_

#hoverme:hover { _x000D_

According to the website, sizeof() is an alias of count(), so they should be running the same code. Perhaps sizeof() has a little bit of overhead because it needs to resolve it to count()? It should be very minimal though.

• There is no limit on objects per bucket.
• There is a limit of 100 buckets per account (you need to request amazon if you need more).
• There is no performance drop even if you store millions of objects in a single bucket.

From docs,

There is no limit to the number of objects that can be stored in a bucket and no difference in performance whether you use many buckets or just a few. You can store all of your objects in a single bucket, or you can organize them across several buckets.

It might be better to use communicate:

from subprocess import Popen, PIPE, STDOUT
p = Popen(['myapp'], stdout=PIPE, stdin=PIPE, stderr=PIPE)
stdout_data = p.communicate(input='data_to_write')[0]

"Better", because of this warning:

Use communicate() rather than .stdin.write, .stdout.read or .stderr.read to avoid deadlocks due to any of the other OS pipe buffers filling up and blocking the child process.

under etc/apache2/apache2.conf, you can find one or more blocks that describe the server directories and permissions

As an example, this is the default configuration

<Directory /var/www/>
   Options Indexes FollowSymLinks
   AllowOverride None
   Require all granted
</Directory>

you can replicate this but change the directory path /var/www/ with the new directory.

Finally, you need to restart the apache server, you can do that from a terminal with the command: sudo service apache2 restart

Another alternative is KMP (Knuth–Morris–Pratt).

The KMP algorithm searches for a length-m substring in a length-n string in worst-case O(n+m) time, compared to a worst-case of O(n·m) for the naive algorithm, so using KMP may be reasonable if you care about worst-case time complexity.

Here's a JavaScript implementation by Project Nayuki, taken from https://www.nayuki.io/res/knuth-morris-pratt-string-matching/kmp-string-matcher.js:

// Searches for the given pattern string in the given text string using the Knuth-Morris-Pratt string matching algorithm.
// If the pattern is found, this returns the index of the start of the earliest match in 'text'. Otherwise -1 is returned.

function kmpSearch(pattern, text) {_x000D_
  if (pattern.length == 0)_x000D_
    return 0; // Immediate match_x000D_

My fork of sql.js has now be merged into the original version, on kriken's repo.

The good documentation is also available on the original repo.

Original answer (outdated)

You should use the newer version of sql.js. It is a port of sqlite 3.8, has a good documentation and is actively maintained (by me). It supports prepared statements, and BLOB data type.

This works for me. Returns the number that Excel displays in the bottom status line when a pivot column is filtered and I need the count of the visible cells.

Global Const DashBoardSheet = "DashBoard"
Global Const ProfileColRng = "$L:$L"
.
.
.
Sub MySub()
Dim myreccnt as long
.
.
.
myreccnt = GetFilteredPivotRowCount(DashBoardSheet, ProfileColRng)
.
.
.
End Sub

Function GetFilteredPivotRowCount(sheetname As String, cntrange As String) As long

Dim reccnt As Long

reccnt = Sheets(sheetname).Range(cntrange).SpecialCells(xlCellTypeVisible).SpecialCells(xlCellTypeConstants).Count - 1

GetFilteredPivotRowCount = reccnt

End Function

netstat -b -a lists the ports in use and gives you the executable that's using each one. I believe you need to be in the administrator group to do this, and I don't know what security implications there are on Vista.

I usually add -n as well to make it a little faster, but adding -b can make it quite slow.

Edit: If you need more functionality than netstat provides, vasac suggests that you try TCPView.

[[ is bash's improvement to the [ command. It has several enhancements that make it a better choice if you write scripts that target bash. My favorites are:

1. It is a syntactical feature of the shell, so it has some special behavior that [ doesn't have. You no longer have to quote variables like mad because [[ handles empty strings and strings with whitespace more intuitively. For example, with [ you have to write

   if [ -f "$file" ]
   

   to correctly handle empty strings or file names with spaces in them. With [[ the quotes are unnecessary:

   if [[ -f $file ]]
   

2. Because it is a syntactical feature, it lets you use && and || operators for boolean tests and < and > for string comparisons. [ cannot do this because it is a regular command and &&, ||, <, and > are not passed to regular commands as command-line arguments.

3. It has a wonderful =~ operator for doing regular expression matches. With [ you might write

   if [ "$answer" = y -o "$answer" = yes ]
   

   With [[ you can write this as

   if [[ $answer =~ ^y(es)?$ ]]
   

   It even lets you access the captured groups which it stores in BASH_REMATCH. For instance, ${BASH_REMATCH[1]} would be "es" if you typed a full "yes" above.

4. You get pattern matching aka globbing for free. Maybe you're less strict about how to type yes. Maybe you're okay if the user types y-anything. Got you covered:

   if [[ $ANSWER = y* ]]
   

Keep in mind that it is a bash extension, so if you are writing sh-compatible scripts then you need to stick with [. Make sure you have the #!/bin/bash shebang line for your script if you use double brackets.

Correct ways in jQuery are -

• $('#test').prop('scrollHeight') OR
• $('#test')[0].scrollHeight OR
• $('#test').get(0).scrollHeight

If all your branches make side-effects or are computationally expensive the following would a semantically-preserving refactoring:

index := func() int {
    if val > 0 {
        return printPositiveAndReturn(val)
    } else {
        return slowlyReturn(-val)  // or slowlyNegate(val)
    }
}();  # exactly one branch will be evaluated

with normally no overhead (inlined) and, most importantly, without cluttering your namespace with a helper functions that are only used once (which hampers readability and maintenance). Live Example

Note if you were to naively apply Gustavo's approach:

    index := printPositiveAndReturn(val);
    if val <= 0 {
        index = slowlyReturn(-val);  // or slowlyNegate(val)
    }

you'd get a program with a different behavior; in case val <= 0 program would print a non-positive value while it should not! (Analogously, if you reversed the branches, you would introduce overhead by calling a slow function unnecessarily.)

Use sudo pico /etc/paths inside the terminal window and change the entries to the one you want to remove, then open a new terminal session.

If you're on a Unix-like system, use gettimeofday and convert the result from microseconds to milliseconds.

Switching to the use of https works. First switch to https rather than ssh keys. git remote set-url origin

It will then request for the git username and password.

Add @JsonInclude(JsonInclude.Include.NON_NULL) (forces Jackson to serialize null values) to the class as well as @JsonIgnore to the password field.

You could of course set @JsonIgnore on createdBy and updatedBy as well if you always want to ignore then and not just in this specific case.

UPDATE

In the event that you do not want to add the annotation to the POJO itself, a great option is Jackson's Mixin Annotations. Check out the documentation

A handle is a pointer or index with no visible type attached to it. Usually you see something like:

 typedef void* HANDLE;
 HANDLE myHandleToSomething = CreateSomething();

So in your code you just pass HANDLE around as an opaque value.

In the code that uses the object, it casts the pointer to a real structure type and uses it:

 int doSomething(HANDLE s, int a, int b) {
     Something* something = reinterpret_cast<Something*>(s);
     return something->doit(a, b);
 }

Or it uses it as an index to an array/vector:

 int doSomething(HANDLE s, int a, int b) {
     int index = (int)s;
     try {
         Something& something = vecSomething[index];
         return something.doit(a, b);
     } catch (boundscheck& e) {
         throw SomethingException(INVALID_HANDLE);
     }
 }

It's a good question... I don't want to lead you astray, so I'm open to other people's answers as much as you are. For me, it really comes down to cost of overhead and what the use of the API is. I prefer consuming web services when creating client software, however I don't like the weight of SOAP. REST, I believe, is lighter weight but I don't enjoy working with it from a client perspective nearly as much.

I'm curious as to what others think.

var formValues = {
    firstName: $('#firstName').val(),
    lastName: $('#lastName').val(),
    phone: $('#phoneNumber').val(),
    address: $('#address').val()
};

Note this will contain the values of the elements at the point in time the object literal was interpreted, not when the properties of the object are accessed. You'd need to write a getter for that.

You'll have problems creating lists without commas. It shouldn't be too hard to transform your data so that it uses commas as separating character.

Once you have commas in there, it's a relatively simple list creation operations:

array1 = [1,2,3]
array2 = [4,5,6]

array3 = [array1, array2]

array4 = [7,8,9]
array5 = [10,11,12]

array3 = [array3, [array4, array5]]

When testing we get:

print(array3)

[[[1, 2, 3], [4, 5, 6]], [[7, 8, 9], [10, 11, 12]]]

And if we test with indexing it works correctly reading the matrix as made up of 2 rows and 2 columns:

array3[0][1]
[4, 5, 6]

array3[1][1]
[10, 11, 12]

Hope that helps.

SQL Server was not configured to allow mixed authentication.

Here are steps to fix:

1. Right-click on SQL Server instance at root of Object Explorer, click on Properties
2. Select Security from the left pane.

3. Select the SQL Server and Windows Authentication mode radio button, and click OK.

   

4. Right-click on the SQL Server instance, select Restart (alternatively, open up Services and restart the SQL Server service).

This is also incredibly helpful for IBM Connections users, my wizards were not able to connect until I fxed this setting.

you can write a function which converts from unsigned long to str, similar to ltostr library function.

char *ultostr(unsigned long value, char *ptr, int base)
{
  unsigned long t = 0, res = 0;
  unsigned long tmp = value;
  int count = 0;

  if (NULL == ptr)
  {
    return NULL;
  }

  if (tmp == 0)
  {
    count++;
  }

  while(tmp > 0)
  {
    tmp = tmp/base;
    count++;
  }

  ptr += count;

  *ptr = '\0';

  do
  {
    res = value - base * (t = value / base);
    if (res < 10)
    {
      * -- ptr = '0' + res;
    }
    else if ((res >= 10) && (res < 16))
    {
        * --ptr = 'A' - 10 + res;
    }
  } while ((value = t) != 0);

  return(ptr);
}

you can refer to my blog here which explains implementation and usage with example.

Open up a command prompt and type java -jar jbpm-installer-3.2.7.jar

I have similar scenario where I need to add filters based on the user input and I chain the where clause.

Here is the sample code.

var votes = db.Votes.Where(r => r.SurveyID == surveyId);
if (fromDate != null)
{
    votes = votes.Where(r => r.VoteDate.Value >= fromDate);
}
if (toDate != null)
{
    votes = votes.Where(r => r.VoteDate.Value <= toDate);
}
votes = votes.Take(LimitRows).OrderByDescending(r => r.VoteDate);

You can put this somewhere global in your code:

$.prototype.enable = function () {
    $.each(this, function (index, el) {
        $(el).removeAttr('disabled');
    });
}

$.prototype.disable = function () {
    $.each(this, function (index, el) {
        $(el).attr('disabled', 'disabled');
    });
}

And then you can write stuff like:

$(".myInputs").enable();
$("#otherInput").disable();

[Linqer] is a SQL to LINQ converter tool. It helps you to learn LINQ and convert your existing SQL statements.

Not every SQL statement can be converted to LINQ, but Linqer covers many different types of SQL expressions. Linqer supports both .NET languages - C# and Visual Basic.

Since this question came up again, I think a good clean approach is using assign.

The code is quite expressive and self-describing:

df = df.assign(Value = lambda x: x.Prices * x.Amount * x.Action.replace({'Buy' : 1, 'Sell' : -1}))

In stead of "live" you need to use "on" event, but assign it to the document object:

Use:

$(document).on('hidden.bs.modal', '#Control_id', function (event) {
// code to run on closing
});

Just run mysqld (don't run as root) from your terminal. Your mysql server will restart and reset everything like shown in the picture below:

And use a command like so:

mysql -u root -h 127.0.0.1

I like some of the answers here, but there is a sed command that should do the trick on any platform:

sed 'y/ABCDEFGHIJKLMNOPQRSTUVWXYZ/abcdefghijklmnopqrstuvwxyz/'

Anyway, it's easy to understand. And knowing about the y command can come in handy sometimes.

You can use the following CSS to make a div 100% of the height of the browser window:

display: block;
position: relative;
bottom: 0;
height: 100%;

This can be done with a CSS hack (see the other answers), but it can also be done very easily with JavaScript.

Set the div's width to (for example) 50%, use JavaScript to check its width, and then set the height accordingly. Here's a code example using jQuery:

$(function() {_x000D_
    var div = $('#dynamicheight');_x000D_
    var width = div.width();_x000D_
    _x000D_
    div.css('height', width);_x000D_
});

#dynamicheight_x000D_
{_x000D_
    width: 50%;_x000D_
    _x000D_
    /* Just for looks: */_x000D_
    background-color: cornflowerblue;_x000D_
    margin: 25px;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
_x000D_
<div id="dynamicheight"></div>

If you want the box to scale with the browser window on resize, move the code to a function and call it on the window resize event. Here's a demonstration of that too (view example full screen and resize browser window):

$(window).ready(updateHeight);_x000D_
$(window).resize(updateHeight);_x000D_
_x000D_
function updateHeight()_x000D_
{_x000D_
    var div = $('#dynamicheight');_x000D_
    var width = div.width();_x000D_
    _x000D_
    div.css('height', width);_x000D_
}

#dynamicheight_x000D_
{_x000D_
    width: 50%;_x000D_
    _x000D_
    /* Just for looks: */_x000D_
    background-color: cornflowerblue;_x000D_
    margin: 25px;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
_x000D_
<div id="dynamicheight"></div>

Here's the C# integrated syntax version:

var items =
    from list in listOfList
    from item in list
    select item;

This is no easy feat.

Tested for PHP 5.3

As i see here, Anonymous Function could help you: http://php.net/manual/en/functions.anonymous.php

What you'll probably need and it's not said before it's how to pass a function without wrapping it inside a on-the-fly-created function. As you'll see later, you'll need to pass the function's name written in a string as a parameter, check its "callability" and then call it.

The function to do check:

if( is_callable( $string_function_name ) ){
    /*perform the call*/
}

Then, to call it, use this piece of code (if you need parameters also, put them on an array), seen at : http://php.net/manual/en/function.call-user-func.php

call_user_func_array( "string_holding_the_name_of_your_function", $arrayOfParameters );

as it follows (in a similar, parameterless, way):

    function funToBeCalled(){
        print("----------------------i'm here");
    }
    function wrapCaller($fun){
        if( is_callable($fun)){
            print("called");
            call_user_func($fun);
        }else{
            print($fun." not called");
        }
    }

    wrapCaller("funToBeCalled");
    wrapCaller("cannot call me");

Here's a class explaining how to do something similar :

<?php
class HolderValuesOrFunctionsAsString{
    private $functions = array();
    private $vars = array();

    function __set($name,$data){
        if(is_callable($data))
            $this->functions[$name] = $data;
        else
            $this->vars[$name] = $data;
    }

    function __get($name){
        $t = $this->vars[$name];
        if(isset($t))
            return $t;
        else{
            $t = $this->$functions[$name];
            if( isset($t))
                return $t;
        }
    }

    function __call($method,$args=null){
        $fun = $this->functions[$method];
        if(isset($fun)){
            call_user_func_array($fun,$args);
        } else {
            // error out
            print("ERROR: Funciton not found: ". $method);
        }
    }
}
?>

and an example of usage

<?php
    /*create a sample function*/
    function sayHello($some = "all"){
    ?>
         <br>hello to <?=$some?><br>
    <?php
    }

    $obj = new HolderValuesOrFunctionsAsString;

    /*do the assignement*/
    $obj->justPrintSomething = 'sayHello'; /*note that the given
        "sayHello" it's a string ! */

    /*now call it*/
    $obj->justPrintSomething(); /*will print: "hello to all" and
        a break-line, for html purpose*/

    /*if the string assigned is not denoting a defined method
         , it's treat as a simple value*/
    $obj->justPrintSomething = 'thisFunctionJustNotExistsLOL';

    echo $obj->justPrintSomething; /*what do you expect to print?
        just that string*/
    /*N.B.: "justPrintSomething" is treated as a variable now!
        as the __set 's override specify"*/

    /*after the assignement, the what is the function's destiny assigned before ? It still works, because it's held on a different array*/
     $obj->justPrintSomething("Jack Sparrow");


     /*You can use that "variable", ie "justPrintSomething", in both ways !! so you can call "justPrintSomething" passing itself as a parameter*/

     $obj->justPrintSomething( $obj->justPrintSomething );
         /*prints: "hello to thisFunctionJustNotExistsLOL" and a break-line*/

    /*in fact, "justPrintSomething" it's a name used to identify both
         a value (into the dictionary of values) or a function-name
         (into the dictionary of functions)*/
?>

Using LINQ to xml if you are using framework 3.5

using System.Xml.Linq;

XDocument xmlFile = XDocument.Load("books.xml"); 
var query = from c in xmlFile.Elements("catalog").Elements("book")    
            select c; 
foreach (XElement book in query) 
{
    book.Attribute("attr1").Value = "MyNewValue";
}
xmlFile.Save("books.xml");

Additionally you can use an app like AutoStart if you dont want to modify the code, to launch an android application at startup: AutoStart - No root

I used this method for updating a label but you could easily change it to a textbox:

Class:

public Class1
{
    public Form_Class formToOutput;

    public Class1(Form_Class f){
        formToOutput = f;
    }

    // Then call this method and pass whatever string
    private void Write(string s)
    {
        formToOutput.MethodToBeCalledByClass(s);
    }
}

Form methods that will do the updating:

public Form_Class{

    // Methods that will do the updating
    public void MethodToBeCalledByClass(string messageToSend)
    {
       if (InvokeRequired) { 
           Invoke(new OutputDelegate(UpdateText),messageToSend); 
       }
    }

    public delegate void OutputDelegate(string messageToSend);
    public void UpdateText(string messageToSend)
    {
       label1.Text = messageToSend;
    }
}

Finally

Just pass the form through the constructor:

Class1 c = new Class1(this);

Like others already wrote, in short:

shared project
reuse on the code (file) level, allowing for folder structure and resources as well

pcl
reuse on the assembly level

What was mostly missing from answers here for me is the info on reduced functionality available in a PCL: as an example you have limited file operations (I was missing a lot of File.IO fuctionality in a Xamarin cross-platform project).

In more detail
shared project:
+ Can use #if when targeting multiple platforms (e. g. Xamarin iOS, Android, WinPhone)
+ All framework functionality available for each target project (though has to be conditionally compiled)
o Integrates at compile time
- Slightly larger size of resulting assemblies
- Needs Visual Studio 2013 Update 2 or higher

pcl:
+ generates a shared assembly
+ usable with older versions of Visual Studio (pre-2013 Update 2)
o dynamically linked
- lmited functionality (subset of all projects it is being referenced by)

If you have the choice, I would recommend going for shared project, it is generally more flexible and more powerful. If you know your requirements in advance and a PCL can fulfill them, you might go that route as well. PCL also enforces clearer separation by not allowing you to write platform-specific code (which might not be a good choice to be put into a shared assembly in the first place).

Main focus of both is when you target multiple platforms, else you would normally use just an ordinary library/dll project.

This macro adds a hyperlink to the worksheet with the same name, I also modify the range to be more flexible, just change the first cell in the code. Works like a charm

Sub hyper()
 Dim cl As Range
 Dim nS As String

 Set MyRange = Sheets("Sheet1").Range("B16")
 Set MyRange = Range(MyRange, MyRange.End(xlDown))

 For Each cl In MyRange
  nS = cl.Value
  cl.Hyperlinks.Add Anchor:=cl, Address:="", SubAddress:="'" & nS & "'" & "!B16", TextToDisplay:=nS
 Next
End Sub

This question already has a great answer, but I ran into the same error, in a different scenario: displaying a List in an EditorTemplate.

I have a model like this:

public class Foo
{
    public string FooName { get; set; }
    public List<Bar> Bars { get; set; }
}

public class Bar
{
    public string BarName { get; set; }
}

And this is my main view:

@model Foo

@Html.TextBoxFor(m => m.Name, new { @class = "form-control" })  
@Html.EditorFor(m => m.Bars)

And this is my Bar EditorTemplate (Bar.cshtml)

@model List<Bar>

<div class="some-style">
    @foreach (var item in Model)
    {
        <label>@item.BarName</label>
    }
</div>

And I got this error:

The model item passed into the dictionary is of type 'Bar', but this dictionary requires a model item of type 'System.Collections.Generic.List`1[Bar]

The reason for this error is that EditorFor already iterates the List for you, so if you pass a collection to it, it would display the editor template once for each item in the collection.

This is how I fixed this problem:

Brought the styles outside of the editor template, and into the main view:

@model Foo

@Html.TextBoxFor(m => m.Name, new { @class = "form-control" })  
<div class="some-style">
    @Html.EditorFor(m => m.Bars)
</div>

And changed the EditorTemplate (Bar.cshtml) to this:

@model Bar

<label>@Model.BarName</label>

You can also try executing the 'convert' utility that comes with imagemagick.

exec("convert pdf_doc.pdf image.jpg");
echo 'image-0.jpg';

using(var client = new System.Net.WebClient()) {
    client.UploadData(address,"PUT",data);
}

console.log( String.fromCharCode(event.charCode) );

no need to map character i guess.

This will work from anywhere, inside Form(), Form_Load(), or any event handler. I posted before, but I don't see it now?!?

public void exit(int exitCode)
{
    if (System.Windows.Forms.Application.MessageLoop)
    {
       // Use this since we are in a running Form
       System.Windows.Forms.Application.Exit();
       System.Environment.Exit(exitCode);
    }
    else
    {
       // Form ended or never .Run
       System.Environment.Exit(exitCode);
    }
} //* end exit()

I have been using Inno Setup for an installer. I'm using 64-bit Windows 7 only. I'm finding that registry entries are being written to

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall

I haven't yet figured out how to get this list to be reported by WMI (although the program is listed as installed in Programs and Features). If I figure it out, I'll try to remember to report back here.

UPDATE:

Entries for 32-bit programs installed on a 64-bit machine go in that registry location. There's more written here:

http://mdb-blog.blogspot.com/2010/09/c-check-if-programapplication-is.html

See my comment that describes 32-bit vs 64-bit behavior in that same post here:

http://mdb-blog.blogspot.com/2010/09/c-check-if-programapplication-is.html?showComment=1300402090679#c861009270784046894

Unfortunately, there doesn't seem to be a way to get WMI to list all programs from the add/remove programs list (aka Programs and Features in Windows 7, not sure about Vista). My current code has dropped WMI in favor of using the registry. The code itself to interrogate the registry is even easier than using WMI. Sample code is in the above link.

For me issue got resolved after following steps :

1. Installing python 32 bit version on windows.
2. Add newly installed python and it's script folder(where pip resides in environment variable)

Issue comes when any application you want to run needs python 32 bit variants and you have 64 bit variant

Note : Once you install python 32 bit variant,dont forget to install all required packages using pip of this new python 32 bit variant

Another thing to try and the answer for me was to uncomment the first export in ~/.zshrc

# If you come from bash you might have to change your $PATH. export PATH=$HOME/bin:/usr/local/bin:$PATH

Basic and simple.

In your adapter simply use this.

((YourParentClass) context).functionToRun();

There isn't a direct 1:1 equivalent.

You can password protect a folder or file using file system permissions. If you are using ASP.Net you can also use some of its built in functions to protect various urls.

If you are trying to port .htaccess files used for url rewriting, check out ISAPI Rewrite: http://www.isapirewrite.com/

you can't use input.click() directly, but you can call this in other element click event.

html

<input type="file">
<button>Select file</button>

js

var botton = document.querySelector('button');
var input = document.querySelector('input');
botton.addEventListener('click', function (e) {
    input.click();
});

this tell you Using hidden file input elements using the click() method

Just delete the table and create a new table with a different name. Also Don't delete entire row for that table. It seems when entire row containing table row is delete it damages the DataBodyRange is damaged

results.show(20, False) or results.show(20, false) depending on whether you are running it on Java/Scala/Python

We can do it by using the below code snippet..

Angular Code:

 export class AppComponent {  
    toggleShowHide: string = "visible";  
 }

HTML Template:

  Enter text to hide or show item in bellow: 
  <input type="text" [(ngModel)]="toggleShowHide">
  <br>
  Toggle Show/hide:
  <div [style.visibility]="toggleShowHide">   
     Final Release Angular 2!
  </div>

Check with "uname -a" and/or "lsb_release -a" to see which version of Linux you are actually running on your AWS instance. The default Amazon AMI image uses YUM for its package manager.

The accepted answer is the correct way to do this in most cases. However, there are some situations where you want to set the cookie header manually. Normally if you set a "Cookie" header it is ignored, but that's because HttpClientHandler defaults to using its CookieContainer property for cookies. If you disable that then by setting UseCookies to false you can set cookie headers manually and they will appear in the request, e.g.

var baseAddress = new Uri("http://example.com");
using (var handler = new HttpClientHandler { UseCookies = false })
using (var client = new HttpClient(handler) { BaseAddress = baseAddress })
{
    var message = new HttpRequestMessage(HttpMethod.Get, "/test");
    message.Headers.Add("Cookie", "cookie1=value1; cookie2=value2");
    var result = await client.SendAsync(message);
    result.EnsureSuccessStatusCode();
}

Now with new JavaScript version (ECMAScript 6 http://es6-features.org/#ClassDefinition) there is a better way to submit requests using nodejs and Promise request (http://www.wintellect.com/devcenter/nstieglitz/5-great-features-in-es6-harmony)

Using library: https://github.com/request/request-promise

npm install --save request
npm install --save request-promise

client:

//Sequential execution for node.js using ES6 ECMAScript
var rp = require('request-promise');

rp({
    method: 'POST',
    uri: 'http://localhost:3000/',
    body: {
        val1 : 1,
        val2 : 2
    },
    json: true // Automatically stringifies the body to JSON
}).then(function (parsedBody) {
        console.log(parsedBody);
        // POST succeeded...
    })
    .catch(function (err) {
        console.log(parsedBody);
        // POST failed...
    });

server:

var express = require('express')
    , bodyParser = require('body-parser');

var app = express();

app.use(bodyParser.json());

app.post('/', function(request, response){
    console.log(request.body);      // your JSON

    var jsonRequest = request.body;
    var jsonResponse = {};

    jsonResponse.result = jsonRequest.val1 + jsonRequest.val2;

    response.send(jsonResponse);
});


app.listen(3000);

As already mentioned, Chrome Extensions don't allow to have inline JavaScript due to security reasons so you can try this workaround as well.

HTML file

<!doctype html>
    <html>
        <head>
            <title>
                Getting Started Extension's Popup
            </title>
            <script src="popup.js"></script>
        </head>
        <body>
            <div id="text-holder">ha</div><br />
            <a class="clickableBtn">
                  hyhy
            </a>
        </body>
    </html>
<!doctype html>

popup.js

window.onclick = function(event) {
    var target = event.target ;
    if(target.matches('.clickableBtn')) {
        var clickedEle = document.activeElement.id ;
        var ele = document.getElementById(clickedEle);
        alert(ele.text);
    }
}

Or if you are having a Jquery file included then

window.onclick = function(event) {
    var target = event.target ;
    if(target.matches('.clickableBtn')) {
        alert($(target).text());
    }
}

Even though you may have a head appending it may not work in all browsers. This was the only method I found to work consistently.

<script type="text/javascript">
if (typeof jQuery == 'undefined') {
  document.write('<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"><\/script>');        
  } 
</script>

Adding an approach to this old question just for the fun of it:

$ cat input.file # file containing input that needs to be processed
a;b;c;d;e
1;2;3;4;5
no delimiter here
124;adsf;15454
foo;bar;is;null;info

$ cat tmp.sh # showing off the script to do the job
#!/bin/bash
delim=';'
while read -r line; do  
    while [[ "$line" =~ "$delim" ]]; do
        line=$(cut -d"$delim" -f 2- <<<"$line")
    done
    echo "$line"
done < input.file

$ ./tmp.sh # output of above script/processed input file
e
5
no delimiter here
15454
info

Besides bash, only cut is used. Well, and echo, I guess.

For your last question, why ? I'll try to explain with what I know

A brief explanation of those three status codes in layman's terms.

• 200 - success (browser requests and get file from server)

If caching is enabled in the server

• 200 (from memory cache) - file found in browser, so browser is not going request from server
• 304 - browser request a file but it is rejected by server

For some files browser is deciding to request from server and for some it's deciding to read from stored (cached) files. Why is this ? Every files has an expiry date, so

If a file is not expired then the browser will use from cache (200 cache).

If file is expired, browser requests server for a file. Server check file in both places (browser and server). If same file found, server refuses the request. As per protocol browser uses existing file.

look at this nginx configuration

location / {
    add_header Cache-Control must-revalidate;
    expires     60;
    etag on;

    ...
}

Here the expiry is set to 60 seconds, so all static files are cached for 60 seconds. So if u request a file again within 60 seconds browser will read from memory (200 memory). If u request after 60 seconds browser will request server (304).

I assumed that the file is not changed after 60 seconds, in that case you would get 200 (ie, updated file will be fetched from server).

So, if the servers are configured with different expiring and caching headers (policies), the status may differ.

In your case you are using cdn, the main purpose of cdn is high availability and fast delivery. Therefore they use multiple servers. Even though it seems like files are in same directory, cdn might use multiple servers to provide u content, if those servers have different configurations. Then these status can change. Hope it helps.

I've had the same problem. This is also caused when there is an ambiguity in classes. My program was trying to invoke a method which was present in two JAR files present in the same location / class path. Delete one JAR file or execute your code such that only one JAR file is used. Check that you are not using same JAR or different versions of the same JAR that contain the same class.

DISP_E_EXCEPTION [step] [] [Z-JAVA-105 Java exception java.lang.NoSuchMethodError(com.example.yourmethod)]

I suggest an approach that does not require Typescript 2.1:

class Person {
    public name: string;
    public address?: string;
    public age: number;

    public constructor(init:Person) {
        Object.assign(this, init);
    }

    public someFunc() {
        // todo
    }
}

let person = new Person(<Person>{ age:20, name:"John" });
person.someFunc();

key points:

• Typescript 2.1 not required, Partial<T> not required
• It supports functions (in comparison with simple type assertion which does not support functions)

I suggest you use a wrapper div or paragraph:

<td><p style="width:50%;">Text only allowed to extend 50% of the cell.</p></td>

And you can make a class out of it:

<td class="linebreak"><p>Text only allowed to extend 50% of the cell.</p></td>

td.linebreak p {
    width: 50%;
}

All of this assuming that you meant 50% as in 50% of the cell.

also if you need to select a sibling with a name rather than the class, you could use the following

var $sibling = $(this).siblings('input[name=bidbutton]');

Works both localhost and on live server without issues, and allows you to extend the delimited list of allowed file-extensions:

var folder = "images/";

$.ajax({
    url : folder,
    success: function (data) {
        $(data).find("a").attr("href", function (i, val) {
            if( val.match(/\.(jpe?g|png|gif)$/) ) { 
                $("body").append( "<img src='"+ folder + val +"'>" );
            } 
        });
    }
});

NOTICE

Apache server has Option Indexes turned on by default - if you use another server like i.e. Express for Node you could use this NPM package for the above to work: https://github.com/expressjs/serve-index

If the files you want to get listed are in /images than inside your server.js you could add something like:

const express = require('express');
const app = express();
const path = require('path');

// Allow assets directory listings
const serveIndex = require('serve-index'); 
app.use('/images', serveIndex(path.join(__dirname, '/images')));

why not simply just give the input field where you want to jump to a id and do a simple focus

$("#newListField").focus();

I also wrote a C#/VB.Net "Export to Excel" library, which uses OpenXML and (more importantly) also uses OpenXmlWriter, so you won't run out of memory when writing large files.

Full source code, and a demo, can be downloaded here:

Export to Excel

It's dead easy to use. Just pass it the filename you want to write to, and a DataTable, DataSet or List<>.

CreateExcelFile.CreateExcelDocument(myDataSet, "MyFilename.xlsx");

And if you're calling it from an ASP.Net application, pass it the HttpResponse to write the file out to.

CreateExcelFile.CreateExcelDocument(myDataSet, "MyFilename.xlsx", Response);

It depends what is the character and what encoding it is in:

• An ASCII character in 8-bit ASCII encoding is 8 bits (1 byte), though it can fit in 7 bits.

• An ISO-8895-1 character in ISO-8859-1 encoding is 8 bits (1 byte).

• A Unicode character in UTF-8 encoding is between 8 bits (1 byte) and 32 bits (4 bytes).

• A Unicode character in UTF-16 encoding is between 16 (2 bytes) and 32 bits (4 bytes), though most of the common characters take 16 bits. This is the encoding used by Windows internally.

• A Unicode character in UTF-32 encoding is always 32 bits (4 bytes).

• An ASCII character in UTF-8 is 8 bits (1 byte), and in UTF-16 - 16 bits.

• The additional (non-ASCII) characters in ISO-8895-1 (0xA0-0xFF) would take 16 bits in UTF-8 and UTF-16.

That would mean that there are between 0.03125 and 0.125 characters in a bit.

I like to use this. There is nothing wrong with using the for loop, I just like using the build-in functions. You could even pass in a boolean argument for typecast or non typecast matching, which in that case you would use a for loop (the filter() method/function does typecast matching (===))

Array.prototype.unique =
function()
{
    return this.filter(
        function(val, i, arr)
        {
            return (i <= arr.indexOf(val));
        }
    );
}

The fast way to get the content of a directory using Java 7 NIO :

import java.nio.file.DirectoryStream;
import java.nio.file.Files;
import java.nio.file.FileSystems;
import java.nio.file.Path;

...

Path dir = FileSystems.getDefault().getPath( filePath );
DirectoryStream<Path> stream = Files.newDirectoryStream( dir );
for (Path path : stream) {
   System.out.println( path.getFileName() );
}
stream.close();

To force LF line endings for all text files, you can create .gitattributes file in top-level of your repository with the following lines (change as desired):

# Ensure all C and PHP files use LF.
*.c         eol=lf
*.php       eol=lf

which ensures that all files that Git considers to be text files have normalized (LF) line endings in the repository (normally core.eol configuration controls which one do you have by default).

Based on the new attribute settings, any text files containing CRLFs should be normalized by Git. If this won't happen automatically, you can refresh a repository manually after changing line endings, so you can re-scan and commit the working directory by the following steps (given clean working directory):

$ echo "* text=auto" >> .gitattributes
$ rm .git/index     # Remove the index to force Git to
$ git reset         # re-scan the working directory
$ git status        # Show files that will be normalized
$ git add -u
$ git add .gitattributes
$ git commit -m "Introduce end-of-line normalization"

or as per GitHub docs:

git add . -u
git commit -m "Saving files before refreshing line endings"
git rm --cached -r . # Remove every file from Git's index.
git reset --hard # Rewrite the Git index to pick up all the new line endings.
git add . # Add all your changed files back, and prepare them for a commit.
git commit -m "Normalize all the line endings" # Commit the changes to your repository.

See also: @Charles Bailey post.

In addition, if you would like to exclude any files to not being treated as a text, unset their text attribute, e.g.

manual.pdf      -text

Or mark it explicitly as binary:

# Denote all files that are truly binary and should not be modified.
*.png binary
*.jpg binary

To see some more advanced git normalization file, check .gitattributes at Drupal core:

# Drupal git normalization
# @see https://www.kernel.org/pub/software/scm/git/docs/gitattributes.html
# @see https://www.drupal.org/node/1542048

# Normally these settings would be done with macro attributes for improved
# readability and easier maintenance. However macros can only be defined at the
# repository root directory. Drupal avoids making any assumptions about where it
# is installed.

# Define text file attributes.
# - Treat them as text.
# - Ensure no CRLF line-endings, neither on checkout nor on checkin.
# - Detect whitespace errors.
#   - Exposed by default in `git diff --color` on the CLI.
#   - Validate with `git diff --check`.
#   - Deny applying with `git apply --whitespace=error-all`.
#   - Fix automatically with `git apply --whitespace=fix`.

I added the solution with threading from jcollado to my Python module easyprocess.

Install:

pip install easyprocess

Example:

from easyprocess import Proc

# shell is not supported!
stdout=Proc('ping localhost').call(timeout=1.5).stdout
print stdout

class Clock {  
        String time;  

        void setTime (String t) {  
           time = t;  
        }  

        String getTime() {  
           return time;  
        }  
}  


class ClockTestDrive {  
   public static void main (String [] args) {  
   Clock c = new Clock;  

   c.setTime("12345")  
   String tod = c.getTime();  
   System.out.println(time: " + tod);  
 }
}  

When you run the program, program starts in mains,

1. object c is created
2. function setTime() is called by the object c
3. the variable time is set to the value passed by
4. function getTime() is called by object c
5. the time is returned
6. It will passe to tod and tod get printed out

According to the Class JSONArray specification:

• An extra , (comma) may appear just before the closing bracket.
• The null value will be inserted when there is , (comma) elision.

So, as I understand it, it should be allowed to write:

[0,1,2,3,4,5,]

But it could happen that some parsers will return the 7 as item count (like IE8 as Daniel Earwicker pointed out) instead of the expected 6.

Edited:

I found this JSON Validator that validates a JSON string against RFC 4627 (The application/json media type for JavaScript Object Notation) and against the JavaScript language specification. Actually here an array with a trailing comma is considered valid just for JavaScript and not for the RFC 4627 specification.

However, in the RFC 4627 specification is stated that:

2.3. Arrays

An array structure is represented as square brackets surrounding zero or more values (or elements). Elements are separated by commas.

array = begin-array [ value *( value-separator value ) ] end-array

To me this is again an interpretation problem. If you write that Elements are separated by commas (without stating something about special cases, like the last element), it could be understood in both ways.

P.S. RFC 4627 isn't a standard (as explicitly stated), and is already obsolited by RFC 7159 (which is a proposed standard) RFC 7159

break just breaks the loop & return gets control back to the caller method.

The above didn't actually work for me as I had expected with Visual Studio 2010. It wouldn't let me access Properties.Resources, said it was inaccessible due to permission issues. I ultimately had to change the Persistence settings in the properties of the resource and then I found how to access it via the Resources.Designer.cs file, where it had an automatic getter that let me access the icon, via MyNamespace.Properties.Resources.NameFromAddingTheResource. That returns an object of type Icon, ready to just use.

In SQLDeveloper browse Tools --> Preferences, as shown in below image.



In the Preferences options expand Database --> select Advanced --> under "Tnsnames Directory" --> Browse the directory where tnsnames.ora present.
Then click on Ok.
as shown in below diagram.

You have Done!

Now you can connect via the TNSnames options.

a = ["foo","bar","baz",'bar','any','much']

indexes = [index for index in range(len(a)) if a[index] == 'bar']

In theory, according to RFC 4329, application/javascript.

The reason it is supposed to be application is not anything to do with whether the type is readable or executable. It's because there are custom charset-determination mechanisms laid down by the language/type itself, rather than just the generic charset parameter. A subtype of text should be capable of being transcoded by a proxy to another charset, changing the charset parameter. This is not true of JavaScript because:

a. the RFC says user-agents should be doing BOM-sniffing on the script to determine type (I'm not sure if any browsers actually do this though);

b. browsers use other information—the including page's encoding and in some browsers the script charset attribute—to determine the charset. So any proxy that tried to transcode the resource would break its users. (Of course in reality no-one ever uses transcoding proxies anyway, but that was the intent.)

Therefore the exact bytes of the file must be preserved exactly, which makes it a binary application type and not technically character-based text.

For the same reason, application/xml is officially preferred over text/xml: XML has its own in-band charset signalling mechanisms. And everyone ignores application for XML, too.

text/javascript and text/xml may not be the official Right Thing, but there are what everyone uses today for compatibility reasons, and the reasons why they're not the right thing are practically speaking completely unimportant.

I solved this issue by:

1. Adding a custom header to the response:

   public ActionResult Index(){
       if (!HttpContext.User.Identity.IsAuthenticated)
       {
           HttpContext.Response.AddHeader("REQUIRES_AUTH","1");
       }
       return View();
   }
   

2. Binding a JavaScript function to the ajaxSuccess event and checking to see if the header exists:

   $(document).ajaxSuccess(function(event, request, settings) {
       if (request.getResponseHeader('REQUIRES_AUTH') === '1') {
          window.location = '/';
       }
   });
   

You can use multiple repositories syntax for the registry entry in your .npmrc file:

registry=http://serverA.url/repository-uri/
//serverB.url/repository-uri/
//serverC.url/repository-uri/:_authToken=00000000-0000-0000-0000-0000000000000
//registry.npmjs.org/

That would make your npm look for packages in different servers.

git pull = git fetch + git merge origin/branch

git pull and git pull origin branch only differ in that the latter will only "update" origin/branch and not all origin/* as git pull does.

git pull origin/branch will just not work because it's trying to do a git fetch origin/branch which is invalid.

Question related: git fetch + git merge origin/master vs git pull origin/master

The column name plays an important role in the descending order:

select <COLUMN_NAME1, COLUMN_NAME2> from >TABLENAME> ORDER BY <COLUMN_NAME THAT MENTIONS TIME> DESC LIMIT 1;

For example: The below-mentioned table(user_details) consists of the column name 'created_at' that has timestamp for the table.

SELECT userid, username FROM user_details ORDER BY created_at DESC LIMIT 1;

Depends on your RDBMS

MS SQL Server

SELECT TOP 10 ...

MySQL

SELECT ... LIMIT 10

Sybase

SET ROWCOUNT 10
SELECT ...

Etc.

I had this error message having started up a second Tomcat server on a Linux server.

$CATALINA_PID was set but the specified file does not exist. Is Tomcat running? Stop aborted.

When starting up the 2nd Tomcat I had set CATALINA_PID as asked but my mistake was to set it to a directory (I assumed Tomcat would write a default file name in there with the pid).

The fix was simply to change my CATALINA_PID to add a file name to the end of it (I chose catalina.pid from the above examples). Next I went to the directory and did a simple:

touch catalina.pid

creating an empty file of the correct name. Then when I did my shutdown.sh I got the message back saying:

PID file is empty and has been ignored.
Tomcat stopped.

I didn't have the option to kill Tomcat as the JVM was in use so I was glad I found this.

As has just happened to me - this can also happen when you add a required property to your model without updating your form. In this case the ValidationSummary will not list the error message.

If you want to insert multiple elements into an array at once check out this Stack Overflow answer: A better way to splice an array into an array in javascript

Also here are some functions to illustrate both examples:

function insertAt(array, index) {
    var arrayToInsert = Array.prototype.splice.apply(arguments, [2]);
    return insertArrayAt(array, index, arrayToInsert);
}

function insertArrayAt(array, index, arrayToInsert) {
    Array.prototype.splice.apply(array, [index, 0].concat(arrayToInsert));
    return array;
}

Finally here is a jsFiddle so you can see it for youself: http://jsfiddle.net/luisperezphd/Wc8aS/

And this is how you use the functions:

// if you want to insert specific values whether constants or variables:
insertAt(arr, 1, "x", "y", "z");

// OR if you have an array:
var arrToInsert = ["x", "y", "z"];
insertArrayAt(arr, 1, arrToInsert);

Using advanced wheres:

CabRes::where('m__Id', 46)
      ->where('t_Id', 2)
      ->where(function($q) {
          $q->where('Cab', 2)
            ->orWhere('Cab', 4);
      })
      ->get();

Or, even better, using whereIn():

CabRes::where('m__Id', 46)
      ->where('t_Id', 2)
      ->whereIn('Cab', $cabIds)
      ->get();

The pattern \d might not be supported by your sed. Try [0-9] or [[:digit:]] instead.

To only print the actual match (not the entire matching line), use a substitution.

sed -n 's/.*\([0-9][0-9]*G[0-9][0-9]*\).*/\1/p'

I the following code I had to replace add a GET-parameter to all references to JS-files EXCEPT one.

<link rel="stylesheet" type="text/css" href="/login/css/ABC.css" />
<script type="text/javascript" language="javascript" src="/localization/DEF.js"></script>
<script type="text/javascript" language="javascript" src="/login/jslib/GHI.js"></script>
<script type="text/javascript" language="javascript" src="/login/jslib/md5.js"></script>
sendRequest('/application/srvc/EXCEPTION.js', handleChallengeResponse, null);
sendRequest('/application/srvc/EXCEPTION.js",handleChallengeResponse, null);

This is the Matcher used:

(?<!EXCEPTION)(\.js)

What that does is look for all occurences of ".js" and if they are preceeded by the "EXCEPTION" string, discard that result from the result array. That's called negative lookbehind. Since I spent a day on finding out how to do this I thought I should share.

As Type.GetType(String) need the Type.AssemblyQualifiedName you should use Assembly.CreateQualifiedName(String, String).

string typeName = "MyNamespace.MyClass"; // Type.FullName
string assemblyName = "MyAssemblyName"; // MyAssembly.FullName or MyAssembly.GetName().Name
string assemblyQualifiedName = Assembly.CreateQualifiedName(assemblyName , typeName);
Type myClassType = Type.GetType(assemblyQualifiedName);

The Version, Culture and PublicKeyToken are not required for assemblyName that's why you can use MyAssembly.GetName().Name.

About Type.GetType(String) :

If the type is in the currently executing assembly or in Mscorlib.dll, it is sufficient to supply the type name qualified by its namespace.

With Firefox, Safari (and other Gecko based browsers) you can easily use textarea.selectionStart, but for IE that doesn't work, so you will have to do something like this:

function getCaret(node) {
  if (node.selectionStart) {
    return node.selectionStart;
  } else if (!document.selection) {
    return 0;
  }

  var c = "\001",
      sel = document.selection.createRange(),
      dul = sel.duplicate(),
      len = 0;

  dul.moveToElementText(node);
  sel.text = c;
  len = dul.text.indexOf(c);
  sel.moveStart('character',-1);
  sel.text = "";
  return len;
}

(complete code here)

I also recommend you to check the jQuery FieldSelection Plugin, it allows you to do that and much more...

Edit: I actually re-implemented the above code:

function getCaret(el) { 
  if (el.selectionStart) { 
    return el.selectionStart; 
  } else if (document.selection) { 
    el.focus(); 

    var r = document.selection.createRange(); 
    if (r == null) { 
      return 0; 
    } 

    var re = el.createTextRange(), 
        rc = re.duplicate(); 
    re.moveToBookmark(r.getBookmark()); 
    rc.setEndPoint('EndToStart', re); 

    return rc.text.length; 
  }  
  return 0; 
}

Check an example here.

Currently in 2011, the various browser vendors cannot agree on how to define offline. Some browsers have a Work Offline feature, which they consider separate to a lack of network access, which again is different to internet access. The whole thing is a mess. Some browser vendors update the navigator.onLine flag when actual network access is lost, others don't.

From the spec:

Returns false if the user agent is definitely offline (disconnected from the network). Returns true if the user agent might be online.

The events online and offline are fired when the value of this attribute changes.

The navigator.onLine attribute must return false if the user agent will not contact the network when the user follows links or when a script requests a remote page (or knows that such an attempt would fail), and must return true otherwise.

Finally, the spec notes:

This attribute is inherently unreliable. A computer can be connected to a network without having Internet access.

    <!--[if IE]>
    <style type='text/css'>
    #header ul#h-menu li a{font-weight:normal!important}
    </style>
    <![endif]-->

will apply that style in all versions of IE.

For variable argument functions like printf and scanf, the arguments are promoted, for example, any smaller integer types are promoted to int, float is promoted to double.

scanf takes parameters of pointers, so the promotion rule takes no effect. It must use %f for float* and %lf for double*.

printf will never see a float argument, float is always promoted to double. The format specifier is %f. But C99 also says %lf is the same as %f in printf:

C99 §7.19.6.1 The fprintf function

l (ell) Specifies that a following d, i, o, u, x, or X conversion specifier applies to a long int or unsigned long int argument; that a following n conversion specifier applies to a pointer to a long int argument; that a following c conversion specifier applies to a wint_t argument; that a following s conversion specifier applies to a pointer to a wchar_t argument; or has no effect on a following a, A, e, E, f, F, g, or G conversion specifier.

9 years too late to the party, but a different approach to your problem (that nobody has mentioned?):

The statement-body works fine with Func<> but won't work with Expression<Func<>>. IQueryable.Select wants an Expression<>, because they can be translated for Entity Framework - Func<> can not.

So you either use the AsEnumerable and start working with the data in memory (not recommended, if not really neccessary) or you keep working with the IQueryable<> which is recommended. There is something called linq query which makes some things easier:

IQueryable<Obj> result = from o in objects
                         let someLocalVar = o.someVar
                         select new Obj
                         {
                           Var1 = someLocalVar,
                           Var2 = o.var2
                         };

with let you can define a variable and use it in the select (or where,...) - and you keep working with the IQueryable until you really need to execute and get the objects.

Afterwards you can Obj[] myArray = result.ToArray()

If you are converting string to float:

import re
A1 = [' "29.0" ',' "65.2" ',' "75.2" ']
float_values = [float(re.search(r'\d+.\d+',number).group()) for number in A1]
print(float_values)
>>> [29.0, 65.2, 75.2]

This link just gave me the best answer:

$ wget --no-clobber --convert-links --random-wait -r -p --level 1 -E -e robots=off -U mozilla http://base.site/dir/

Worked like a charm.

This is a very interesting question and I hope my thought below could contribute an way of solution to it. This method do give a flat list without indexing, but it does have list and unlist to avoid the nesting structures. I'm not sure about the speed since I don't know how to benchmark it.

a_list<-list()
for(i in 1:3){
  a_list<-list(unlist(list(unlist(a_list,recursive = FALSE),list(rnorm(2))),recursive = FALSE))
}
a_list

The ToString method of any object is supposed to return a string representation of that object.

int var1 = 2;

string var2 = var1.ToString();

Hi I know this topic is old but there is a much better way to differentiate an Array in Node.js from any other Object have a look at the docs.

var util = require('util');

util.isArray([]); // true
util.isArray({}); // false

var obj = {};
typeof obj === "Object" // true

This is the solution that I've came up with:

<form name = "form1" id = "form1" action = "#" method = "post">
  <select name = "DropDownList1" id = "DropDownList1">
<?php
$arr = array('Yes', 'No', 'Fine' ); // create array so looping is easier
for( $i = 1; $i <= 3; $i++ ) // loop starts at first value and ends at last value
{
  $selected = ''; // keep selected at nothing
  if( isset( $_POST['go'] ) ) // check if form was submitted
  {
    if( $_POST['DropDownList1'] == $i ) // if the value of the dropdownlist is equal to the looped variable
    {
      $selected = 'selected = "selected"'; // if is equal, set selected = "selected"
    }
  }
  // note: if value is not equal, selected stays defaulted to nothing as explained earlier
  echo '<option value = "' . $i . '"' . $selected . '>' . $arr[$i] . '</option>'; // echo the option element to the page using the $selected variable
}
?>
  </select> <!-- finish the form in html -->
  <input type="text" value="" name="name">
  <input type="submit" value="go" name="go">
</form>

The code I have works as long as the values are integers in some numeric order ( ascending or descending ). What it does is starts the dropdownlist in html, and adds each option element in php code. It will not work if you have random values though, i.e: 1, 4, 2, 7, 6. Each value must be unique.

Which Oracle client are you using?

Oracle 64bit 11g client isn't support in PLSQL Developer. Try to install 32bits client.

A lot of these answers won't actually work, having tried them myself. Give this a go:

string filepath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
DirectoryInfo d = new DirectoryInfo(filepath);

foreach (var file in d.GetFiles("*.txt"))
{
      Directory.Move(file.FullName, filepath + "\\TextFiles\\" + file.Name);
}

It will move all .txt files on the desktop to the folder TextFiles.

I had the same problem, to solve it set specific user from domain in iis -> action sidebar->Basic Settings -> Connect as... -> specific user

await new Promise(resolve => setTimeout(resolve, 1000))

This happened to me when my SourceTree application crashed during staging. And on the command line, it seemed like the previous git add had been corrupted. If this is the case, try:

git init
git add -A
git commit -m 'Fix bad repo'
git push

On the last command, you might need to set the branch.

git push --all origin master

Bear in mind that this is enough if you haven't done any branching or any of that sort. In that case, make sure you push to the correct branch like git push origin develop.

I had the same problem, and none of the above solutions worked. Actually, the file include/boost/version.hpp could not be read (by the cmake script launched by jenkins).

I had to manually change the permission of the (boost) library (even though jenkins belongs to the group, but that is another problem linked to jenkins that I could not figure out):

chmod o+wx ${BOOST_ROOT} -R # allow reading/execution on the whole library
#chmod g+wx ${BOOST_ROOT} -R # this did not suffice, strangely, but it is another story I guess

Use flatMap. If a value is present, flatMap returns a sequential Stream containing only that value, otherwise returns an empty Stream. So there is no need to use ifPresent() . Example:

list.stream().map(data -> data.getSomeValue).map(this::getOptinalValue).flatMap(Optional::stream).collect(Collectors.toList());

It is happening Due to:

<p><script>var _nwls=[];if(window.jQuery&&window.jQuery.find){_nwls=jQuery.find(".fw_link_newWindow");}else{if(document.getElementsByClassName){_nwls=document.getElementsByClassName("fw_link_newWindow");}else{if(document.querySelectorAll){_nwls=document.querySelectorAll(".fw_link_newWindow");}else{document.write('<scr'+'ipt src="http://static.websimages.com/static/global/js/sizzle/sizzle.min.js"><\/scr'+'ipt>');if(window.Sizzle){_nwls=Sizzle(".fw_link_newWindow");}}}}var numlinks=_nwls.length;for(var i=0;i<numlinks;i++){_nwls[i].target="_blank";}</script></p>

Remove <p></p> around the script.

You can use the Bean Comparator to sort on any property in your custom class.

If you are beginner, I think this tutorial may give basic idea about What Servlet is ...

Some valuable points are below from the given link.

Servlet technology is used to create web application which resides at server side and generates dynamic web page.

Servlet can be described in many ways, depending on the context.

• Servlet is a technology i.e. used to create web application.
• Servlet is an API that provides many interfaces and classes including documentations.
• Servlet is an interface that must be implemented for creating any servlet.
• Servlet is a class that extend the capabilities of the servers and respond to the incoming request. It can respond to any type of requests.
• Servlet is a web component that is deployed on the server to create dynamic web page. Reference:Here.

I can't find toByteArray() as @atrioom said, so I use StringWriter, please try:

public void writeListToJsonArray() throws IOException {  

    //your list
    final List<Event> list = new ArrayList<Event>(2);
    list.add(new Event("a1","a2"));
    list.add(new Event("b1","b2"));


    final StringWriter sw =new StringWriter();
    final ObjectMapper mapper = new ObjectMapper();
    mapper.writeValue(sw, list);
    System.out.println(sw.toString());//use toString() to convert to JSON

    sw.close(); 
}

Or just use ObjectMapper#writeValueAsString:

    final ObjectMapper mapper = new ObjectMapper();
    System.out.println(mapper.writeValueAsString(list));

There is no such feature in markdown, however you can always use HTML inside markdown:

<a href="http://example.com/" target="_blank">example</a>

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

Use substring

String strOut = "abcdefghijklmnopqrtuvwxyz"
String result = strOut.substring(0, 8) + "...";// count start in 0 and 8 is excluded
System.out.pritnln(result);

Note: substring(int first, int second) takes two parameters. The first is inclusive and the second is exclusive.

Recursively

const toFormData = (f => f(f))(h => f => f(x => h(h)(f)(x)))(f => fd => pk => d => {_x000D_
  if (d instanceof Object) {_x000D_
    Object.keys(d).forEach(k => {_x000D_
      const v = d[k]_x000D_
      if (pk) k = `${pk}[${k}]`_x000D_
      if (v instanceof Object && !(v instanceof Date) && !(v instanceof File)) {_x000D_
        return f(fd)(k)(v)_x000D_
      } else {_x000D_

Latest version of Geany supports it (only on Linux, though)

The Flexible does the trick

new Container(
       child: Row(
         children: <Widget>[
            Flexible(
               child: new Text("A looooooooooooooooooong text"))
                ],
        ));

This is the official doc https://flutter.dev/docs/development/ui/layout#lay-out-multiple-widgets-vertically-and-horizontally on how to arrange widgets.

Remember that Flexible and also Expanded, should only be used within a Column, Row or Flex, because of the Incorrect use of ParentDataWidget.

The solution is not the mere Flexible

Using Regex (from detectmobilebrowsers.com):

Here's a function that uses an insanely long and comprehensive regex which returns a true or false value depending on whether or not the user is browsing with a mobile.

The Original Answer

You can do this by simply running through a list of devices and checking if the useragent matches anything like so:

  function detectMob() {
    const toMatch = [
        /Android/i,
        /webOS/i,
        /iPhone/i,
        /iPad/i,
        /iPod/i,
        /BlackBerry/i,
        /Windows Phone/i
    ];

    return toMatch.some((toMatchItem) => {
        return navigator.userAgent.match(toMatchItem);
    });
}

However since you believe that this method is unreliable, You could assume that any device that had a resolution of 800x600 or less was a mobile device too, narrowing your target even more (although these days many mobile devices have much greater resolutions than this)

i.e

  function detectMob() {
    return ( ( window.innerWidth <= 800 ) && ( window.innerHeight <= 600 ) );
  }

Reference:

Given sheet 2:

ColumnA
-------
apple
orange

You can flag the rows in sheet 1 where a value exists in sheet 2:

ColumnA  ColumnB
-------  --------------
pear     =IF(ISERROR(VLOOKUP(A1,Sheet2!A:A,1,FALSE)),"Keep","Delete")
apple    =IF(ISERROR(VLOOKUP(A2,Sheet2!A:A,1,FALSE)),"Keep","Delete")
cherry   =IF(ISERROR(VLOOKUP(A3,Sheet2!A:A,1,FALSE)),"Keep","Delete")
orange   =IF(ISERROR(VLOOKUP(A4,Sheet2!A:A,1,FALSE)),"Keep","Delete")
plum     =IF(ISERROR(VLOOKUP(A5,Sheet2!A:A,1,FALSE)),"Keep","Delete")

The resulting data looks like this:

ColumnA  ColumnB
-------  --------------
pear     Keep
apple    Delete
cherry   Keep
orange   Delete
plum     Keep

You can then easily filter or sort sheet 1 and delete the rows flagged with 'Delete'.

jQuery takes care of this for you. The first argument to your .each() callback function is the index of the current iteration of the loop. The second being the current matched DOM element So:

$('#list option').each(function(index, element){
  alert("Iteration: " + index)
});

This is not specifically for eclipse, but the way I got around this was by creating a symbolic link to my maven repository and pointing it to something like "C:\R". Then I added the following to my settings.xml file:

<localRepository>C:\R</localRepository>

The maven repository path was contributing to the length problems in my windows machine.

The message is fairly self-explanatory; your working directory should not be the NumPy source directory when you invoke Python; NumPy should be installed and your working directory should be anything but the directory where it lives.

All the above answers are correct. But you can achieve this in just one line. Please try following declaration and you will get all the comma separated values in a String list.

private @Value("#{T(java.util.Arrays).asList(projectProperties['my.list.of.strings'])}") List<String> myList;

And also you need to have the following line defined in your xml configuration.

<util:properties id="projectProperties" location="/project.properties"/>

just replace the path and file name of your properties file. And you are good to go. :)

Hope this helps you. Cheers.

You can use a lambda expression, e.g:

sales['time_hour'] = sales.timestamp.apply(lambda x: x.hour)

It depends on what encoding you use. If you want to convert utf-8 encoded hex to string, use this:

function fromHex(hex,str){
  try{
    str = decodeURIComponent(hex.replace(/(..)/g,'%$1'))
  }
  catch(e){
    str = hex
    console.log('invalid hex input: ' + hex)
  }
  return str
}

For the other direction use this:

function toHex(str,hex){
  try{
    hex = unescape(encodeURIComponent(str))
    .split('').map(function(v){
      return v.charCodeAt(0).toString(16)
    }).join('')
  }
  catch(e){
    hex = str
    console.log('invalid text input: ' + str)
  }
  return hex
}

Use Max-Age=-1 rather than "Expires". It is shorter, less picky about the syntax, and Max-Age takes precedence over Expires anyway.

I messed around with this for awhile. Here was my scenario:

I have two types, metrics1 and metrics2, each with different properties:

type metrics1 = {
    a: number;
    b: number;
    c: number;
}

type metrics2 = {
    d: number;
    e: number;
    f: number;
}

At a point in my code, I created an object that is the intersection of these two types because this object will hold all of their properties:

const myMetrics: metrics1 & metrics2 = {
    a: 10,
    b: 20,
    c: 30,
    d: 40,
    e: 50,
    f: 60
};

Now, I need to dynamically reference the properties of that object. This is where we run into index signature errors. Part of the issue can be broken down based on compile-time checking and runtime checking. If I reference the object using a const, I will not see that error because TypeScript can check if the property exists during compile time:

const myKey = 'a';
console.log(myMetrics[myKey]); // No issues, TypeScript has validated it exists

If, however, I am using a dynamic variable (e.g. let), then TypeScript will not be able to check if the property exists during compile time, and will require additional help during runtime. That is where the following typeguard comes in:

function isValidMetric(prop: string, obj: metrics1 & metrics2): prop is keyof (metrics1 & metrics2) {
    return prop in obj;
}

This reads as,"If the obj has the property prop then let TypeScript know that prop exists in the intersection of metrics1 & metrics2." Note: make sure you surround metrics1 & metrics2 in parentheses after keyof as shown above, or else you will end up with an intersection between the keys of metrics1 and the type of metrics2 (not its keys).

Now, I can use the typeguard and safely access my object during runtime:

let myKey:string = '';
myKey = 'a';
if (isValidMetric(myKey, myMetrics)) {
    console.log(myMetrics[myKey]);
}

As you can see in the generated SQL statements the difference is not the "OR" as some may suspect. It is how the WHERE and JOIN is placed.

Example1 (same joined table) :

(example from https://docs.djangoproject.com/en/dev/topics/db/queries/#spanning-multi-valued-relationships)

Blog.objects.filter(entry__headline__contains='Lennon', entry__pub_date__year=2008)

This will give you all the Blogs that have one entry with both (entry_headline_contains='Lennon') AND (entry__pub_date__year=2008), which is what you would expect from this query. Result: Book with {entry.headline: 'Life of Lennon', entry.pub_date: '2008'}

Example 2 (chained)

Blog.objects.filter(entry__headline__contains='Lennon').filter(entry__pub_date__year=2008)

This will cover all the results from Example 1, but it will generate slightly more result. Because it first filters all the blogs with (entry_headline_contains='Lennon') and then from the result filters (entry__pub_date__year=2008).

The difference is that it will also give you results like: Book with {entry.headline: 'Lennon', entry.pub_date: 2000}, {entry.headline: 'Bill', entry.pub_date: 2008}

In your case

I think it is this one you need:

Book.objects.filter(inventory__user__profile__vacation=False, inventory__user__profile__country='BR')

And if you want to use OR please read: https://docs.djangoproject.com/en/dev/topics/db/queries/#complex-lookups-with-q-objects

The above suggested solution to check for the ANDROID_ID worked for me until I updated today to the latest SDK tools released with Android 2.2.

Therefore I currently switched to the following solution which works so far with the disadvantage however that you need to put the PHONE_STATE read permission (<uses-permission android:name="android.permission.READ_PHONE_STATE"/>)

private void checkForDebugMode() {
    ISDEBUGMODE = false; //(Secure.getString(getApplicationContext().getContentResolver(), Secure.ANDROID_ID) == null);

    TelephonyManager man = (TelephonyManager) getApplicationContext().getSystemService(Context.TELEPHONY_SERVICE);
    if(man != null){
        String devId = man.getDeviceSoftwareVersion();
        ISDEBUGMODE = (devId == null);
    }
} 

Open you working copy folder in console (terminal) and choose commands below. To see last changes: If you have commited last changes use:

svn diff -rPREV

If you left changes in working copy (that's bad practice) than use:

svn diff

To see log of commits: If you're working in branch:

svn log --stop-on-copy 

If you're working with trunk:

svn log | head

or just

svn log

For Objective C Projects created using Xcode 8 and now opening in Xcode 9, it is showing the same error as mentioned in the question.

To fix that, Press the + button in Build Settings and select Add User-Defined Setting as shown in the image below

Then in the new row created add SWIFT_VERSION as key and 3.2 as value like below.

It will fix the error for objective c projects.

Some APIs want you to supply the appropriate "Accept" header in the request to get the wanted response type.

For example if an API can return data in XML and JSON and you want the JSON result, you would need to set the HttpWebRequest.Accept property to "application/json".

HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(requestUri);
httpWebRequest.Method = WebRequestMethods.Http.Get;
httpWebRequest.Accept = "application/json";

Python 3.6 will add literal string interpolation similar to Ruby's string interpolation. Starting with that version of Python (which is scheduled to be released by the end of 2016), you will be able to include expressions in "f-strings", e.g.

name = "Spongebob Squarepants"
print(f"Who lives in a Pineapple under the sea? {name}.")

Prior to 3.6, the closest you can get to this is

name = "Spongebob Squarepants"
print("Who lives in a Pineapple under the sea? %(name)s." % locals())

The % operator can be used for string interpolation in Python. The first operand is the string to be interpolated, the second can have different types including a "mapping", mapping field names to the values to be interpolated. Here I used the dictionary of local variables locals() to map the field name name to its value as a local variable.

The same code using the .format() method of recent Python versions would look like this:

name = "Spongebob Squarepants"
print("Who lives in a Pineapple under the sea? {name!s}.".format(**locals()))

There is also the string.Template class:

tmpl = string.Template("Who lives in a Pineapple under the sea? $name.")
print(tmpl.substitute(name="Spongebob Squarepants"))

numbers = [1, 2, 3]
numsum = sum(list(numbers))
print(numsum)

This would work, if your are trying to Sum up a list.

Select your results by clicking in the top left corner, right click and select "Copy with Headers". Paste in excel. Done!

I think this means that module.exports in your ./app/routes module is not assigned to be a function so therefore require('./app/routes') does not resolve to a function so therefore, you cannot call it as a function like this require('./app/routes')(app, passport).

Show us ./app/routes if you want us to comment further on that.

It should look something like this;

module.exports = function(app, passport) {
    // code here
}

You are exporting a function that can then be called like require('./app/routes')(app, passport).

One other reason a similar error could occur is if you have a circular module dependency where module A is trying to require(B) and module B is trying to require(A). When this happens, it will be detected by the require() sub-system and one of them will come back as null and thus trying to call that as a function will not work. The fix in that case is to remove the circular dependency, usually by breaking common code into a third module that both can separately load though the specifics of fixing a circular dependency are unique for each situation.

You can't always rely on MIME type..

According to: http://filext.com/file-extension/CSV

text/comma-separated-values, text/csv, application/csv, application/excel, application/vnd.ms-excel, application/vnd.msexcel, text/anytext

There are various MIME types for CSV.

Your probably best of checking extension, again not very reliable, but for your application it may be fine.

$info = pathinfo($_FILES['uploadedfile']['tmp_name']);

if($info['extension'] == 'csv'){
 // Good to go
}

Code untested.

Use mysql-connector-python. I prefer to install it with pip from PyPI:

pip install --allow-external mysql-connector-python mysql-connector-python

Have a look at its documentation and examples.

If you are going to use pooling make sure your database has enough connections available as the default settings may not be enough.

The smallest change to fix this would be to change

onClick="document.getElementById("datepicker").click()">

to

onClick="$('#datepicker').click()">

click() is a jQuery method. Also, you had a collision between the double-quotes used for the HTML element attribute and those use for the JavaScript function argument.

String fields with the binary flag set will always be case sensitive. Should you need a case sensitive search for a non binary text field use this: SELECT 'test' REGEXP BINARY 'TEST' AS RESULT;

Try the following parameter:

-nc, --no-clobber: skip downloads that would download to existing files.

Sample usage:

wget -nc http://example.com/pic.png

using _.some from lodash: https://lodash.com/docs/4.17.11#some

const array1AndArray2NotEqual = 
          _.some(array1, (a1, idx) => a1.key1 !== array2[idx].key1 
                                     || a1.key2 !== array2[idx].key2 
                                     || a1.key3 !== array2[idx].key3);

Type "set" and you will get a list of all the current variables. If you want something to persist put it in ~/.bashrc or ~/.bash_profile (if you're using bash)

If your problem is really just this simple, you don't need regex:

s[s.find("(")+1:s.find(")")]

It will impact your script if you work with multi-byte text that you substring from. If this is the case, I higly recommend enabling mb_* functions in your php.ini or do this ini_set("mbstring.func_overload", 2);

$string = "'test1', 'test2', 'test3',";_x000D_
echo mb_substr($string, 0, -1);

select distinct object_name(sc.id)
from syscolumns sc,sysobjects so  
where sc.name like '%col_name%' and so.type='U'

Bash alternative (for Bash scripting):

psql -h localhost -U postgres -tc \
"SELECT 1 FROM pg_user WHERE usename = 'my_user'" \
| grep -q 1 \
|| psql -h localhost -U postgres \
-c "CREATE ROLE my_user LOGIN PASSWORD 'my_password';"

(isn't the answer for the question! it is only for those who may be useful)

The following is a slightly better extension method:

public static string ToEnumString<TEnum>(this int enumValue)
{
    var enumString = enumValue.ToString();
    if (Enum.IsDefined(typeof(TEnum), enumValue))
    {
        enumString = ((TEnum) Enum.ToObject(typeof (TEnum), enumValue)).ToString();
    }
    return enumString;

A semaphore is a way to lock a resource so that it is guaranteed that while a piece of code is executed, only this piece of code has access to that resource. This keeps two threads from concurrently accesing a resource, which can cause problems.

For rails 4, based on this article and this original answer

Person
  .unscoped # See the caution note below. Maybe you want default scope here, in which case just remove this line.
  .where( # Begin a where clause
    where(:name => "John").where(:lastname => "Smith")  # join the scopes to be OR'd
    .where_values  # get an array of arel where clause conditions based on the chain thus far
    .inject(:or)  # inject the OR operator into the arels 
    # ^^ Inject may not work in Rails3. But this should work instead:
    .joins(" OR ")
    # ^^ Remember to only use .inject or .joins, not both
  )  # Resurface the arels inside the overarching query

Note the article's caution at the end:

Rails 4.1+

Rails 4.1 treats default_scope just as a regular scope. The default scope (if you have any) is included in the where_values result and inject(:or) will add or statement between the default scope and your wheres. That's bad.

To solve that, you just need to unscope the query.

Modern Django have self template tag filesizeformat:

Formats the value like a human-readable file size (i.e. '13 KB', '4.1 MB', '102 bytes', etc.).

For example:

{{ value|filesizeformat }}

If value is 123456789, the output would be 117.7 MB.

More info: https://docs.djangoproject.com/en/1.10/ref/templates/builtins/#filesizeformat

Sure, use the .format method. E.g.,

print('{:10s} {:3d}  {:7.2f}'.format('xxx', 123, 98))
print('{:10s} {:3d}  {:7.2f}'.format('yyyy', 3, 1.0))
print('{:10s} {:3d}  {:7.2f}'.format('zz', 42, 123.34))

will print

xxx        123    98.00
yyyy         3     1.00
zz          42   123.34

You can adjust the field sizes as desired. Note that .format works independently of print to format a string. I just used print to display the strings. Brief explanation:

10s format a string with 10 spaces, left justified by default

3d format an integer reserving 3 spaces, right justified by default

7.2f format a float, reserving 7 spaces, 2 after the decimal point, right justfied by default.

There are many additional options to position/format strings (padding, left/right justify etc), String Formatting Operations will provide more information.

Update for f-string mode. E.g.,

text, number, other_number = 'xxx', 123, 98
print(f'{text:10} {number:3d}  {other_number:7.2f}')

For right alignment

print(f'{text:>10} {number:3d}  {other_number:7.2f}')

Edit: it seems nginx now supports error_log stderr; as mentioned in Anon's answer.

You can send the logs to /dev/stdout. In nginx.conf:

daemon off;
error_log /dev/stdout info;

http {
  access_log /dev/stdout;
  ...
}

edit: May need to run ln -sf /proc/self/fd /dev/ if using running certain docker containers, then use /dev/fd/1 or /dev/fd/2

df.loc[df['A'] == df['B'], 'C'] = 0
df.loc[df['A'] > df['B'], 'C'] = 1
df.loc[df['A'] < df['B'], 'C'] = -1

Easy to solve using indexing. The first line of code reads like so, if column A is equal to column B then create and set column C equal to 0.

I used postman chrome extension until it became deprecated. Chrome extension also less usable and powerful then native postman application. So, it became not very convenient to use chrome extension. I have found next approach:

1. copy any request in chrome/any other browser as CURL request (image 1)
2. import to postman copied request (image 2)
3. save imported request in postman's list

A possible pattern for this issue is that you dont have connection to Nexus and basically you want to build the project in offline mode. But when you import the project Idea tries to download Maven dependencies automatically.. and fails. You set Work Offline checkbox in Settings, but its too late: something was already broken during initial download attempt. Neither of the options listed here worked for me to resolve this. Instead I did the following:

1. first created empty Java (not Maven) project
2. checked Work Offline option in Maven settings
3. added my project as a Maven module to this new project

This way it worked.

The answer by @akrun certainly does the trick. For future googlers who want to understand why, here is an explanation...

The new variable needs to be created first.

The variable "valueBin" needs to be already in the df in order for the conditional assignment to work. Essentially, the syntax of the code is correct. Just add one line in front of the code chuck to create this name --

df$newVariableName <- NA

Then you continue with whatever conditional assignment rules you have, like

df$newVariableName[which(df$oldVariableName<=250)] <- "<=250"

I blame whoever wrote that package's error message... The debugging was made especially confusing by that error message. It is irrelevant information that you have two arrays in the df with different lengths. No. Simply create the new column first. For more details, consult this post https://www.r-bloggers.com/translating-weird-r-errors/

In 2014 I still think my point holds:

IMHO, this discussion got blown out of proportion quite a bit. Quoting the aforementioned blog post:

Most JavaScript utility libraries, such as Underscore, Valentine, and wu, rely on the “native-first dual approach.” This approach prefers native implementations, falling back to vanilla JavaScript only if the native equivalent is not supported. But jsPerf revealed an interesting trend: the most efficient way to iterate over an array or array-like collection is to avoid the native implementations entirely, opting for simple loops instead.

As if "simple loops" and "vanilla Javascript" are more native than Array or Object method implementations. Jeez ...

It certainly would be nice to have a single source of truth, but there isn't. Even if you've been told otherwise, there is no Vanilla God, my dear. I'm sorry. The only assumption that really holds is that we are all writing JavaScript code that aims at performing well in all major browsers, knowing that all of them have different implementations of the same things. It's a bitch to cope with, to put it mildly. But that's the premise, whether you like it or not.

Maybe all of you are working on large scale projects that need twitterish performance so that you really see the difference between 850,000 (Underscore.js) vs. 2,500,000 (Lodash) iterations over a list per second right now!

I for one am not. I mean, I worked on projects where I had to address performance issues, but they were never solved or caused by neither Underscore.js nor Lodash. And unless I get hold of the real differences in implementation and performance (we're talking C++ right now) of, let’s say, a loop over an iterable (object or array, sparse or not!), I rather don't get bothered with any claims based on the results of a benchmark platform that is already opinionated.

It only needs one single update of, let’s say, Rhino to set its Array method implementations on fire in a fashion that not a single "medieval loop methods perform better and forever and whatnot" priest can argue his/her way around the simple fact that all of a sudden array methods in Firefox are much faster than his/her opinionated brainfuck. Man, you just can't cheat your runtime environment by cheating your runtime environment! Think about that when promoting ...

your utility belt

... next time.

So to keep it relevant:

• Use Underscore.js if you're into convenience without sacrificing native'ish.
• Use Lodash if you're into convenience and like its extended feature catalogue (deep copy, etc.) and if you're in desperate need of instant performance and most importantly don't mind settling for an alternative as soon as native API's outshine opinionated workarounds. Which is going to happen soon. Period.
• There's even a third solution. DIY! Know your environments. Know about inconsistencies. Read their (John-David's and Jeremy's) code. Don't use this or that without being able to explain why a consistency/compatibility layer is really needed and enhances your workflow or improves the performance of your application. It is very likely that your requirements are satisfied with a simple polyfill that you're perfectly able to write yourself. Both libraries are just plain vanilla with a little bit of sugar. They both just fight over who's serving the sweetest pie. But believe me, in the end both are only cooking with water. There's no Vanilla God so there can't be no Vanilla pope, right?

Choose whatever approach fits your needs the most. As usual. I'd prefer fallbacks on actual implementations over opinionated runtime cheats anytime, but even that seems to be a matter of taste nowadays. Stick to quality resources like http://developer.mozilla.com and http://caniuse.com and you'll be just fine.

What you are looking for is called Model persistence in sklearn words and it is documented in introduction and in model persistence sections.

So you have initialized your classifier and trained it for a long time with

clf = some.classifier()
clf.fit(X, y)

After this you have two options:

1) Using Pickle

import pickle
# now you can save it to a file
with open('filename.pkl', 'wb') as f:
    pickle.dump(clf, f)

# and later you can load it
with open('filename.pkl', 'rb') as f:
    clf = pickle.load(f)

2) Using Joblib

from sklearn.externals import joblib
# now you can save it to a file
joblib.dump(clf, 'filename.pkl') 
# and later you can load it
clf = joblib.load('filename.pkl')

One more time it is helpful to read the above-mentioned links

To understand circular dependencies, you need to remember that Python is essentially a scripting language. Execution of statements outside methods occurs at compile time. Import statements are executed just like method calls, and to understand them you should think about them like method calls.

When you do an import, what happens depends on whether the file you are importing already exists in the module table. If it does, Python uses whatever is currently in the symbol table. If not, Python begins reading the module file, compiling/executing/importing whatever it finds there. Symbols referenced at compile time are found or not, depending on whether they have been seen, or are yet to be seen by the compiler.

Imagine you have two source files:

File X.py

def X1:
    return "x1"

from Y import Y2

def X2:
    return "x2"

File Y.py

def Y1:
    return "y1"

from X import X1

def Y2:
    return "y2"

Now suppose you compile file X.py. The compiler begins by defining the method X1, and then hits the import statement in X.py. This causes the compiler to pause compilation of X.py and begin compiling Y.py. Shortly thereafter the compiler hits the import statement in Y.py. Since X.py is already in the module table, Python uses the existing incomplete X.py symbol table to satisfy any references requested. Any symbols appearing before the import statement in X.py are now in the symbol table, but any symbols after are not. Since X1 now appears before the import statement, it is successfully imported. Python then resumes compiling Y.py. In doing so it defines Y2 and finishes compiling Y.py. It then resumes compilation of X.py, and finds Y2 in the Y.py symbol table. Compilation eventually completes w/o error.

Something very different happens if you attempt to compile Y.py from the command line. While compiling Y.py, the compiler hits the import statement before it defines Y2. Then it starts compiling X.py. Soon it hits the import statement in X.py that requires Y2. But Y2 is undefined, so the compile fails.

Please note that if you modify X.py to import Y1, the compile will always succeed, no matter which file you compile. However if you modify file Y.py to import symbol X2, neither file will compile.

Any time when module X, or any module imported by X might import the current module, do NOT use:

from X import Y

Any time you think there may be a circular import you should also avoid compile time references to variables in other modules. Consider the innocent looking code:

import X
z = X.Y

Suppose module X imports this module before this module imports X. Further suppose Y is defined in X after the import statement. Then Y will not be defined when this module is imported, and you will get a compile error. If this module imports Y first, you can get away with it. But when one of your co-workers innocently changes the order of definitions in a third module, the code will break.

In some cases you can resolve circular dependencies by moving an import statement down below symbol definitions needed by other modules. In the examples above, definitions before the import statement never fail. Definitions after the import statement sometimes fail, depending on the order of compilation. You can even put import statements at the end of a file, so long as none of the imported symbols are needed at compile time.

Note that moving import statements down in a module obscures what you are doing. Compensate for this with a comment at the top of your module something like the following:

#import X   (actual import moved down to avoid circular dependency)

In general this is a bad practice, but sometimes it is difficult to avoid.

Use the DateTime.ToUniversalTime method.

Just type in the following command: taskkill /f /im (program name) To find out the im of your program open task manager and look at the process while your program is running. After the program has run a process will disappear from the task manager; that is your program.

Here is what I use:

function repeat(str, num) {
        var holder = [];
        for(var i=0; i<num; i++) {
            holder.push(str);
        }
        return holder.join('');
    }

In Docker release v1.0, binding a mount of a file or directory on the host machine can be done by the given command:

$ docker run -v /host:/container ...

The above volume could be used as a persistent storage on the host running Docker.

All I know is a Clean does not do what "make clean" used to do - if I Clean a solution I would expect it delete obj and bin files/folders such that it builds like is was a fresh checkout of the source. In my experience though I often find times where a Clean and Build or Rebuild still produces strange errors on source that is known to compile and what is required is a manual deletion of the bin/obj folders, then it will build.

You can't do this without some browser specific code, since they implement text select ranged slightly differently. However, there are plugins that abstract this away. For exactly what you're after, there's the jQuery Caret (jCaret) plugin.

For your code to get the position you could do something like this:

$("#myTextInput").bind("keydown keypress mousemove", function() {
  alert("Current position: " + $(this).caret().start);
});

You can test it here.

I think, below procedure help you to what you are looking for.

 CREATE PROCEDURE [dbo].[FindEmployeeRecord]
        @EmployeeID nvarchar(Max)
    AS
    BEGIN
    DECLARE @sqLQuery VARCHAR(MAX)
    Declare @AnswersTempTable Table
    (  
        EmpId int,         
        EmployeeName nvarchar (250),       
        EmployeeAddress nvarchar (250),  
        PostalCode nvarchar (50),
        TelephoneNo nvarchar (50),
        Email nvarchar (250),
        status nvarchar (50),  
        Sex nvarchar (50) 
    )

    Set @sqlQuery =
    'select e.EmpId,e.EmployeeName,e.Email,e.Sex,ed.EmployeeAddress,ed.PostalCode,ed.TelephoneNo,ed.status
    from Employee e
    join EmployeeDetail ed on e.Empid = ed.iEmpID
    where Convert(nvarchar(Max),e.EmpId) in ('+@EmployeeId+')
    order by EmpId'
    Insert into @AnswersTempTable
    exec (@sqlQuery)
    select * from @AnswersTempTable
    END

The R-inferno, or the basic R-documentation will explain why using df$* is not the best approach here. From the help page for "[" :

"Indexing by [ is similar to atomic vectors and selects a list of the specified element(s). Both [[ and $ select a single element of the list. The main difference is that $ does not allow computed indices, whereas [[ does. x$name is equivalent to x[["name", exact = FALSE]]. Also, the partial matching behavior of [[ can be controlled using the exact argument. "

I recommend using the [row,col] notation instead. Example:

Rgames: foo   
         x    y z  
   [1,] 1e+00 1 0  
   [2,] 2e+00 2 0  
   [3,] 3e+00 1 0  
   [4,] 4e+00 2 0  
   [5,] 5e+00 1 0  
   [6,] 6e+00 2 0  
   [7,] 7e+00 1 0  
   [8,] 8e+00 2 0  
   [9,] 9e+00 1 0  
   [10,] 1e+01 2 0  
Rgames: foo<-as.data.frame(foo)

Rgames: foo[foo$y==2,3]<-foo[foo$y==2,1]
Rgames: foo
       x y     z
1  1e+00 1 0e+00
2  2e+00 2 2e+00
3  3e+00 1 0e+00
4  4e+00 2 4e+00
5  5e+00 1 0e+00
6  6e+00 2 6e+00
7  7e+00 1 0e+00
8  8e+00 2 8e+00
9  9e+00 1 0e+00
10 1e+01 2 1e+01

import psutil

for p in psutil.process_iter(attrs=['pid', 'name']):
    if "itunes.exe" in (p.info['name']).lower():
        print("yes", (p.info['name']).lower())

for python 3.7

import psutil

for p in psutil.process_iter(attrs=['pid', 'name']):
    if p.info['name'] == "itunes.exe":
        print("yes", (p.info['name']))

This works for python 3.8 & psutil 5.7.0, windows

IMHO what the best solution is depends to some extent on how you store time in the rest of the database (and the rest of your application)

Personally I have worked with SQLite and try to always use unix timestamps for storing absolute time, so when dealing with the time of day (like you ask for) I do what Glen Solsberry writes in his answer and store the number of seconds since midnight

When taking this general approach people (including me!) reading the code are less confused if I use the same standard everywhere

I had some production code that could only handle 20 employees at a time, below is the framework for the code. I just copied the production code and removed stuff below.

ALTER procedure GetEmployees
    @ClientId varchar(50)
as
begin
    declare @EEList table (employeeId varchar(50));
    declare @EE20 table (employeeId varchar(50));

    insert into @EEList select employeeId from Employee where (ClientId = @ClientId);

    -- Do 20 at a time
    while (select count(*) from @EEList) > 0
    BEGIN
      insert into @EE20 select top 20 employeeId from @EEList;

      -- Call sp here

      delete @EEList where employeeId in (select employeeId from @EE20)
      delete @EE20;
    END;

  RETURN
end

This appears to be a problem with the way mac is handling reading the /etc/hosts file. See for example http://youtrack.jetbrains.com/issue/IDEA-96865

Adding the hostname to the hosts file as bond described should not be required, but it does solve the problem.

The following query will find the documents with required string case insensitively and with global occurrence also

var name = 'Peter';
    db.User.find({name:{
                         $regex: new RegExp(name, "ig")
                     }
                },function(err, doc) {
                                     //Your code here...
              });

Just change the SqlCommand.CommandText instead of creating a new SqlCommand every time. There is no need to close and reopen the connection.

// Create the first command and execute
var command = new SqlCommand("<SQL Command>", myConnection);
var reader = command.ExecuteReader();

// Change the SQL Command and execute
command.CommandText = "<New SQL Command>";
command.ExecuteNonQuery();

Another way without JavaScript is to use <form autocomplete="off"> to prevent the browser from re-filling the form with the last values.

Tested this only with a single <input type="text"> inside the form, but works fine in current Chrome and Firefox, unfortunately not in IE10.

I would like to give you a background on Universal CRT this would help you in understanding as to why the system should be updated before installing vc_redist.x64.exe.

1. A large portion of the C-runtime moved into the OS in Windows 10 (ucrtbase.dll) and is serviced just like any other OS DLL (e.g. kernel32.dll). It is no longer serviced by Visual Studio directly. MSU packages are the file type for Windows Updates.
2. In order to get the Windows 10 Universal CRT to earlier OSes, Windows Update packages were created to bring this OS component downlevel. KB2999226 brings the Windows 10 RTM Universal CRT to downlevel platforms (Windows Vista through Windows 8.1). KB3118401 brings Windows 10 November Update to the Universal CRT to downlevel platforms.
   • Windows XP (latest SP) is an exception here. Windows Servicing does not provide downlevel packages for that OS, so Visual Studio (Visual C++) provides a mechanism to install the UCRT into System32 via the VCRedist and MSMs.
3. The Windows Universal Runtime is included in the VC Redist exe package as it has dependency on the Windows Universal Runtime (KB2999226).
4. Windows 10 is the only OS that ships the UCRT in-box. All prior OSes obtain the UCRT via Windows Update only. This applies to all Vista->8.1 and associated Server SKUs.

For Windows 7, 8, and 8.1 the Windows Universal Runtime must be installed via KB2999226. However it has a prerequisite update KB2919355 which contains updates that facilitate installing the KB2999226 package.

Why does KB2999226 not always install when the runtime is installed from the redistributable? What could prevent KB2999226 from installing as part of the runtime?

The UCRT MSU included in the VCRedist is installed by making a call into the Windows Update service and the KB can fail to install based upon Windows Update service activity/state:

1. If the machine has not updated to the required servicing baseline, the UCRT MSU will be viewed as being “Not Applicable”. Ensure KB2919355 is installed. Also, there were known issues with KB2919355 so before this the following hotfix should be installed. KB2939087 KB2975061
2. If the Windows Update service is installing other updates when the VCRedist installs, you can either see long delays or errors indicating the machine is busy.
   • This one can be resolved by waiting and trying again later (which may be why installing via Windows Update UI at a later time succeeds).

3. If the Windows Update service is in a non-ready state, you can see errors reflecting that.

   • We recently investigated a failure with an error code indicating the WUSA service was shutting down.

4. To identify if the prerequisite KB2919355 is installed there are 2 options:

   1. Registry key: 64bit hive

      HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing\Packages\Package_for_KB2919355~31bf3856ad364e35~amd64~~6.3.1.14
      CurrentState = 112
      

      32bit hive

      HKLM\SOFTWARE\[WOW6432Node\]Microsoft\Windows\CurrentVersion\Component Based Servicing\Packages\Package_for_KB2919355~31bf3856ad364e35~x86~~6.3.1.14
      CurrentState = 112
      

   2. Or check the file version of:

      C:\Windows\SysWOW64\wuaueng.dll
      C:\Windows\System32\wuaueng.dll
      

      is 7.9.9600.17031 or later

This works:

myElement.className = 'foo bar baz';

You access the property in the wrong way. With the $this->$my_value = .. syntax, you set the property with the name of the value in $my_value. What you want is $this->my_value = ..

$var = "my_value";
$this->$var = "test";

is the same as

$this->my_value = "test";

To fix a few things from your example, the code below is a better aproach

class my_class {

    public  $my_value = array();

    function __construct ($value) {
        $this->my_value[] = $value;
    }

    function set_value ($value) {
        if (!is_array($value)) {
            throw new Exception("Illegal argument");
        }

        $this->my_value = $value;
    }

    function add_value($value) {
        $this->my_value = $value;
    }
}

$a = new my_class ('a');
$a->my_value[] = 'b';
$a->add_value('c');
$a->set_value(array('d'));

This ensures, that my_value won't change it's type to string or something else when you call set_value. But you can still set the value of my_value direct, because it's public. The final step is, to make my_value private and only access my_value over getter/setter methods

<pre>
function sortObjectByVal(obj){  
var keysSorted = Object.keys(obj).sort(function(a,b){return obj[b]-obj[a]});
var newObj = {};
for(var x of keysSorted){
    newObj[x] = obj[x];
}
return newObj;

}
var list = {"you": 100, "me": 75, "foo": 116, "bar": 15};
console.log(sortObjectByVal(list));
</pre>

I had the same problem, then I did this two steps:

• Enable "Allow less secure apps" on your google account security policy.
• Restart your local servers.

It's all about the key bindings which one can simply achieve from .vimrc configurations. As far as clipboard is concerned you can use :set clipboard unnamed and the yank from vim will go to system clipboard. Anyways, whichever one you end up using I suggest using this vimrc config , it contains a whole lot of plugins and bindings which will make your experience smooth.

If it's any help to anyone, give permission to "IIS_IUSRS" group.

Note that if you can't find "IIS_IUSRS", try prepending it with your server's name, like "MySexyServer\IIS_IUSRS".

In regards to your code, see @Coulton. You'll need to use JavaScript.

Checkout either FitText (it does work in IE, they just ballsed their site somehow) or BigText.

FitText will allow you to scale some text in relation to the container it is in, while BigText is more about resizing different sections of text to be the same width within the container.

BigText will set your string to exactly the width of the container, whereas FitText is less pixel perfect. It starts by setting the font-size at 1/10th of the container element's width. It doesn't work very well with all fonts by default, but it has a setting which allows you to decrease or increase the 'power' of the re-size. It also allows you to set a min and max font-size. It will take a bit of fiddling to get working the first time, but does work great.

http://marabeas.io <- playing with it currently here. As far as I understand, BigText wouldn't work in my context at all.

For those of you using Angularjs, here's an Angular version of FitText I've made.

Here's a LESS mixin you can use to make @humanityANDpeace's solution a little more pretty:

@mqIterations: 19;
.fontResize(@i) when (@i > 0) {
    @media all and (min-width: 100px * @i) { body { font-size:0.2em * @i; } }
    .fontResize((@i - 1));
}
.fontResize(@mqIterations);

And an SCSS version thanks to @NIXin!

$mqIterations: 19;
@mixin fontResize($iterations) { 
    $i: 1;
