Programs & Examples On #Getselection

The solution is to set the proxy to "native" as below

Go to "Window-> Preferences -> General -> Network Connection" and change the Settings "Active Provider-> Native". It worked for me.

No need to pass anything in. The function used for addEventListener will automatically have this bound to the current element. Simply use this in your function:

productLineSelect.addEventListener('change', getSelection, false);

function getSelection() {
    var value = this.options[this.selectedIndex].value;
    alert(value);
}

Here's the fiddle: http://jsfiddle.net/dJ4Wm/

If you want to pass arbitrary data to the function, wrap it in your own anonymous function call:

productLineSelect.addEventListener('change', function() {
    foo('bar');
}, false);

function foo(message) {
    alert(message);
}

Here's the fiddle: http://jsfiddle.net/t4Gun/

If you want to set the value of this manually, you can use the call method to call the function:

var self = this;
productLineSelect.addEventListener('change', function() {
    getSelection.call(self);
    // This'll set the `this` value inside of `getSelection` to `self`
}, false);

function getSelection() {
    var value = this.options[this.selectedIndex].value;
    alert(value);
}

I suggest going straight for the model approach in Swing. After you've put the component in the panel and layout manager, don't even bother keeping a specific reference to it.

If you really want the widget, then you can test each with isSelected, or maintain a Map<ButtonModel,JRadioButton>.

I'd like to share a pattern that I've been using to solve these kinds of problems. It works rather well I think. Of course, it only works if you have control over what calls the constructor. Example below

public class MyClass
{
    public static async Task<MyClass> Create()
    {
        var myClass = new MyClass();
        await myClass.Initialize();
        return myClass;
    }

    private MyClass()
    {

    }

    private async Task Initialize()
    {
        await Task.Delay(1000); // Do whatever asynchronous work you need to do
    }
}

Basicly what we do is we make the constructor private and make our own public static async method that is responsible for creating an instance of MyClass. By making the constructor private and keeping the static method within the same class we have made sure that noone could "accidently" create an instance of this class without calling the proper initialization methods. All the logic around the creation of the object is still contained within the class (just within a static method).

var myClass1 = new MyClass() // Cannot be done, the constructor is private
var myClass2 = MyClass.Create() // Returns a Task that promises an instance of MyClass once it's finished
var myClass3 = await MyClass.Create() // asynchronously creates and initializes an instance of MyClass

Implemented on the current scenario it would look something like:

public partial class Page2 : PhoneApplicationPage
{
    public static async Task<Page2> Create()
    {
        var page = new Page2();
        await page.getWritings();
        return page;
    }

    List<Writing> writings;

    private Page2()
    {
        InitializeComponent();
    }

    private async Task getWritings()
    {
        string jsonData = await JsonDataManager.GetJsonAsync("1");
        JObject obj = JObject.Parse(jsonData);
        JArray array = (JArray)obj["posts"];

        for (int i = 0; i < array.Count; i++)
        {
            Writing writing = new Writing();
            writing.content = JsonDataManager.JsonParse(array, i, "content");
            writing.date = JsonDataManager.JsonParse(array, i, "date");
            writing.image = JsonDataManager.JsonParse(array, i, "url");
            writing.summary = JsonDataManager.JsonParse(array, i, "excerpt");
            writing.title = JsonDataManager.JsonParse(array, i, "title");

            writings.Add(writing);
        }

        myLongList.ItemsSource = writings;
    }
}

And instead of doing

var page = new Page2();

You would be doing

var page = await Page2.Create();

The two options I use are:

list1.AddRange(list2);

or

list1.Concat(list2);

However I noticed as I used that when using the AddRange method with a recursive function, that calls itself very often I got an SystemOutOfMemoryException because the maximum number of dimensions was reached.

(Message Google Translated)
The array dimensions exceeded the supported range.

Using Concat solved that issue.

execl("/home/vlc", 
  "/home/vlc", "/home/my movies/the movie i want to see.mkv", 
  (char*) NULL);

You need to specify all arguments, included argv[0] which isn't taken from the executable.

Also make sure the final NULL gets cast to char*.

Playing with above answers, this one works for me

REPLACE(REPLACE(column_name , '\n', ''), '\r', '')

Using map.keySet(), you can get a set of keys. Then convert this set into List by:

List<String> l = new ArrayList<String>(map.keySet());

And then use l.get(int) method to access keys.

If this is a simple project, you should be able to drag the txt file right into the project folder. Specifically, the "project folder" would be the highest level folder. I tried to do this (for a homework project that I'm doing) by putting the txt file in the src folder, but that didn't work. But finally I figured out to put it in the project file.

A good tutorial for this is http://www.vogella.com/articles/JavaIO/article.html. I used this as an intro to i/o and it helped.

Use SpecialCells to delete only the rows that are visible after autofiltering:

ActiveSheet.Range("$A$1:$I$" & lines).SpecialCells _
    (xlCellTypeVisible).EntireRow.Delete

If you have a header row in your range that you don't want to delete, add an offset to the range to exclude it:

ActiveSheet.Range("$A$1:$I$" & lines).Offset(1, 0).SpecialCells _
    (xlCellTypeVisible).EntireRow.Delete

With the recent update to melt.data.table, we can now melt multiple columns. With that, we can do:

require(data.table) ## 1.9.5
melt(setDT(df), id=1:2, measure=patterns("^Q3.2", "^Q3.3"), 
     value.name=c("Q3.2", "Q3.3"), variable.name="loop_number")
 #    id       time loop_number         Q3.2        Q3.3

You can get the development version from here.

The basic setup of decorators is like this:

InputStream fileStream = new FileInputStream(filename);
InputStream gzipStream = new GZIPInputStream(fileStream);
Reader decoder = new InputStreamReader(gzipStream, encoding);
BufferedReader buffered = new BufferedReader(decoder);

The key issue in this snippet is the value of encoding. This is the character encoding of the text in the file. Is it "US-ASCII", "UTF-8", "SHIFT-JIS", "ISO-8859-9", …? there are hundreds of possibilities, and the correct choice usually cannot be determined from the file itself. It must be specified through some out-of-band channel.

For example, maybe it's the platform default. In a networked environment, however, this is extremely fragile. The machine that wrote the file might sit in the neighboring cubicle, but have a different default file encoding.

Most network protocols use a header or other metadata to explicitly note the character encoding.

In this case, it appears from the file extension that the content is XML. XML includes the "encoding" attribute in the XML declaration for this purpose. Furthermore, XML should really be processed with an XML parser, not as text. Reading XML line-by-line seems like a fragile, special case.

Failing to explicitly specify the encoding is against the second commandment. Use the default encoding at your peril!

You can use Thread.getCurrentThread.getId(), but why would you want to do that when LogRecord objects managed by the logger already have the thread Id. I think you are missing a configuration somewhere that logs the thread Ids for your log messages.

Use the ALLOW_PAGE_LOCKS clause of ALTER/CREATE INDEX:

ALTER INDEX indexname ON tablename SET (ALLOW_PAGE_LOCKS = OFF);

Simply type the following command on the command line inside the virtual environment:

deactivate

httpListener.Prefixes.Add("http://*:4444/");

you use "*" so you execute following cmd as admin

netsh http add urlacl url=http://*:4444/ user=username

no use +, must use *, because you spec *:4444~.

<?php
$start = strtotime("12:00");
$end = // Run query to get datetime value from db
$elapsed = $end - $start;
echo date("H:i", $elapsed);
?>

The oddly named "blame" command does this. If you use Tortoise, it gives you a "from revision" dialog, then a file listing with a line by line indicator of Revision number and author next to it.

If you right click on the revision info, you can bring up a "Show log" dialog that gives full checkin information, along with other files that were part of the checkin.

OK, so first of all the http://angular-ui.github.io/bootstrap/ has a <modal> directive and the $dialog service and both of those can be used to open modal windows.

The difference is that with the <modal> directive content of a modal is embedded in a hosting template (one that triggers modal window opening). The $dialog service is far more flexible and allow you to load modal's content from a separate file as well as trigger modal windows from any place in AngularJS code (this being a controller, a service or another directive).

Not sure what you mean exactly by "using JavaScript code" but assuming that you mean any place in AngularJS code the $dialog service is probably a way to go.

It is very easy to use and in its simplest form you could just write:

$dialog.dialog({}).open('modalContent.html');  

To illustrate that it can be really triggered by any JavaScript code here is a version that triggers modal with a timer, 3 seconds after a controller was instantiated:

function DialogDemoCtrl($scope, $timeout, $dialog){
  $timeout(function(){
    $dialog.dialog({}).open('modalContent.html');  
  }, 3000);  
}

This can be seen in action in this plunk: http://plnkr.co/edit/u9HHaRlHnko492WDtmRU?p=preview

Finally, here is the full reference documentation to the $dialog service described here: https://github.com/angular-ui/bootstrap/blob/master/src/dialog/README.md

Found a very easily implemented fix. Set the focus to a text element that has a font size of 50px on completion of the form. It does not seem to work if the text element is hidden but hiding this element is easily done by setting the elements color properties to have no opacity.

It seems that the version "20140702" of the example link in the question was the final version, because I downloaded this file on the 12th November 2014, i.e. the version from the 2nd of July 2014 was still the latest version on 12th of November. When I try manually all the possible versions/dates between today in this date, then I always get a page with error code "404" (file not found), which indicates that no new version was released since the 12th of November.

You simply use the destroy() method to delete the specified widgets like this:

lbl = tk.Label(....)

btn = tk.Button(....., command=lambda: lbl.destroy())

Using this you can completely destroy the specific widgets.

A Pending Intent is a token you give to some app to perform an action on your apps' behalf irrespective of whether your application process is alive or not.

I think the documentation is sufficiently detailed: Pending Intent docs.

Just think of use-cases for Pending Intents like (Broadcasting Intents, scheduling alarms) and the documentation will become clearer and meaningful.

It is impossible to terminate a thread unless the code running in that thread checks for and allows termination.

You said: "Sadly I must kill/restart it ... I don't have complete control over the contents of the thread and for my situation it requires a restart"

If the contents of the thread does not allow for termination of its exectuion then you can not terminate that thread.

In your post you said: "My first attempt was with ExecutorService but I can't seem to find a way for it restart a task. When I use .shutdownnow()..."

If you look at the source of "shutdownnow" it just runs through and interrupts the currently running threads. This will not stop their execution unless the code in those threads checks to see if it has been ineterrupted and, if so, stops execution itself. So shutdownnow is probably not doing what you think.

Let me illustrate what I mean when I say that the contents of the thread must allow for that thread to be terminated:

myExecutor.execute(new Runnable() {
 public void run() {
  while (true) {
    System.out.println("running");
  }
 }
 });
myExecutor.shutdownnow();

That thread will continue to run forever, even though shutdownnow was called, because it never checks to see if it has been terminated or not. This thread, however, will shut down:

myExecutor.execute(new Runnable() {
 public void run() {
  while (!Thread.interrupted()) {
    System.out.println("running");
  }
 }
 });
myExecutor.shutdownnow();

Since this thread checks to see whether or not it has been interrupted / shut down / terminated.

So if you want a thread that you can shut down, you need to make sure it checks to see if it has been interrupted. If you want a thread that you can "shut down" and "restart" you can make a runnable that can take new tasks as was mentioned before.

Why can you not shut down a running thread? Well I actually lied, you can call "yourThread.stop()" but why is this a bad idea? The thread could be in a synchronized (or other critical section, but we will limit ourselves to setions guarded by the syncrhonized key word here) section of code when you stop it. synch blocks are supposed to be executed in their entirity and only by one thread before being accessed by some other thread. If you stop a thread in the middle of a synch block, the protection put into place by the synch block is invalidated and your program will get into an unknown state. Developers make put stuff in synch blocks to keep things in synch, if you use threadInstance.stop() you destroy the meaning of synchronize, what the developer of that code was trying to accomplish and how the developer of that code expected his synchronized blocks to behave.

If you want to convert list into the CSV format .........

List<String> ids = new ArrayList<String>();
ids.add("1");
ids.add("2");
ids.add("3");
ids.add("4");

// CSV format
String csv = ids.toString().replace("[", "").replace("]", "")
            .replace(", ", ",");

// CSV format surrounded by single quote 
// Useful for SQL IN QUERY

String csvWithQuote = ids.toString().replace("[", "'").replace("]", "'")
            .replace(", ", "','");

This issue was driving me crazy as it suddenly happened without doing any changes to the project. I've tried all suggested solutions in this thread (and other related) and none of them solved the problem.

The only thing that differed from my other projects (which compiled fine), was that this project name was containing an accent (a french accent, "é"). I've renamed the project and all related files, and it finally worked !

Maybe this is related to updating to Xcode 10, because this project was working well before...

EDIT : it also seems to failed when using a project with - in project name…

You can do something like this in your click or celldoubleclick event of your grid(if you used one)

if(dgEmp.CurrentRow.Index != -1)
 {
    employ.Id = (Int32)dgEmp.CurrentRow.Cells["Id"].Value;
    //Some other stuff here
 }

Then do something like this in your Delete Button:

using(Context context = new Context())
{
     var entry = context.Entry(employ);
     if(entry.State == EntityState.Detached)
     {
        //Attached it since the record is already being tracked
        context.Employee.Attach(employ);
     }                             
     //Use Remove method to remove it virtually from the memory               
     context.Employee.Remove(employ);
     //Finally, execute SaveChanges method to finalized the delete command 
     //to the actual table
     context.SaveChanges();

     //Some stuff here
}

Alternatively, you can use a LINQ Query instead of using LINQ To Entities Query:

var query = (from emp in db.Employee
where emp.Id == employ.Id
select emp).Single();

employ.Id is used as filtering parameter which was already passed from the CellDoubleClick Event of your DataGridView.

fieldset {
  overflow: hidden
}

.class {
  float: left;
  clear: none;
}

label {
  float: left;
  clear: both;
  display:initial;
}

input[type=radio],input.radio {
  float: left;
  clear: both;     
}

Here are some examples of setdefault to show its usefulness:

"""
d = {}
# To add a key->value pair, do the following:
d.setdefault(key, []).append(value)

# To retrieve a list of the values for a key
list_of_values = d[key]

# To remove a key->value pair is still easy, if
# you don't mind leaving empty lists behind when
# the last value for a given key is removed:
d[key].remove(value)

# Despite the empty lists, it's still possible to 
# test for the existance of values easily:
if d.has_key(key) and d[key]:
    pass # d has some values for key

# Note: Each value can exist multiple times!

print e

I think that the best solution currently for springBoot 2.0 is using profiles

@RunWith(SpringRunner.class)
@SpringBootTest(classes = Application.class, webEnvironment = WebEnvironment.DEFINED_PORT)
@ActiveProfiles("test")
public class ExcludeAutoConfigIntegrationTest {
    // ...
} 

spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration

anyway in the following link give 6 different alternatives to solve this.

I too experienced the same issues with the border formatting not being shown using entrophy's code but a few little fixes and now the table is expandable and displays all css styling rules you may add.

to css add:

#maintable{width: 100%}    

then here is the new javascript:

    function moveScroll(){
    var scroll = $(window).scrollTop();
    var anchor_top = $("#maintable").offset().top;
    var anchor_bottom = $("#bottom_anchor").offset().top;
    if (scroll > anchor_top && scroll < anchor_bottom) {
        clone_table = $("#clone");
        if(clone_table.length === 0) {          
            clone_table = $("#maintable").clone();
            clone_table.attr({id: "clone"})
            .css({
                position: "fixed",
                "pointer-events": "none",
                 top:0
            })
            .width($("#maintable").width());

            $("#table-container").append(clone_table);
            // dont hide the whole table or you lose border style & 
            // actively match the inline width to the #maintable width if the 
            // container holding the table (window, iframe, div) changes width          
            $("#clone").width($("#maintable").width());
            // only the clone thead remains visible
            $("#clone thead").css({
                visibility:"visible"
            });
            // clone tbody is hidden
            $("#clone tbody").css({
                visibility:"hidden"
            });
            // add support for a tfoot element
            // and hide its cloned version too
            var footEl = $("#clone tfoot");
            if(footEl.length){
                footEl.css({
                    visibility:"hidden"
                });
            }
        }
    } 
    else {
        $("#clone").remove();
    }
}
$(window).scroll(moveScroll);

This error happens when the branch you are switching to, has changes that your current branch doesn't have.

If you are seeing this error when you try to switch to a new branch, then your current branch is probably behind one or more commits. If so, run:

git fetch

You should also remove dependencies which may also conflict with the destination branch.

For example, for iOS developers:

pod deintegrate

then try checking out a branch again.

If the desired branch isn't new you can either cherry pick a commit and fix the conflicts or stash the changes and then fix the conflicts.

1. Git Stash (recommended)

git stash
git checkout <desiredBranch>
git stash apply

2. Cherry pick (more work)

git add <your file>
git commit -m "Your message"
git log

Copy the sha of your commit. Then discard unwanted changes:

git checkout .
git checkout -- . 
git clean -f -fd -fx

Make sure your branch is up to date:

git fetch

Then checkout to the desired branch

git checkout <desiredBranch>

Then cherry pick the other commit:

git cherry-pick <theSha>

Now fix the conflict.

3. Otherwise, your other option is to abandon your current branches changes with:

git checkout -f branch

The interface keyword indicates that you are declaring a traditional interface class in Java.
The @interface keyword is used to declare a new annotation type.

See docs.oracle tutorial on annotations for a description of the syntax.
See the JLS if you really want to get into the details of what @interface means.

You can use the text editing controller to manipulate the value inside a textfield.

var textController = new TextEditingController();

Now, create a new textfield and set textController as the controller for the textfield as shown below.

 new TextField(controller: textController)

Now, create a RaisedButton anywhere in your code and set the desired text in the onPressed method of the RaisedButton.

new RaisedButton(
       onPressed: () {
          textController.text = "New text";
       }
    ),

Your code is not doing what I think you think it is doing. The line for item in z: will iterate through z, each time making item equal to one single element of z. The original item list is therefore overwritten before you've done anything with it.

I think you want something like this:

item = [0,1,2,3,4,5,6,7,8,9]

for element in item:
    if element not in z:
        print element

But you could easily do this like:

[x for x in item if x not in z]

or (if you don't mind losing duplicates of non-unique elements):

set(item) - set(z)

You are presumably encountering an exception and the program is exiting because of this (with a traceback). The first thing to do therefore is to catch that exception, before exiting cleanly (maybe with a message, example given).

Try something like this in your main routine:

import sys, traceback

def main():
    try:
        do main program stuff here
        ....
    except KeyboardInterrupt:
        print "Shutdown requested...exiting"
    except Exception:
        traceback.print_exc(file=sys.stdout)
    sys.exit(0)

if __name__ == "__main__":
    main()

You can use all functions from Long, if you put the number into "(" ")". That way you can cast the long to an int:

<c:out value="${map[(1).intValue()]}"/>

You can capture the system environment variables with a vbs script, but you need a bat script to actually change the current environment variables, so this is a combined solution.

Create a file named resetvars.vbs containing this code, and save it on the path:

Set oShell = WScript.CreateObject("WScript.Shell")
filename = oShell.ExpandEnvironmentStrings("%TEMP%\resetvars.bat")
Set objFileSystem = CreateObject("Scripting.fileSystemObject")
Set oFile = objFileSystem.CreateTextFile(filename, TRUE)

set oEnv=oShell.Environment("System")
for each sitem in oEnv 
    oFile.WriteLine("SET " & sitem)
next
path = oEnv("PATH")

set oEnv=oShell.Environment("User")
for each sitem in oEnv 
    oFile.WriteLine("SET " & sitem)
next

path = path & ";" & oEnv("PATH")
oFile.WriteLine("SET PATH=" & path)
oFile.Close

create another file name resetvars.bat containing this code, same location:

@echo off
%~dp0resetvars.vbs
call "%TEMP%\resetvars.bat"

When you want to refresh the environment variables, just run resetvars.bat

Apologetics:

The two main problems I had coming up with this solution were

a. I couldn't find a straightforward way to export environment variables from a vbs script back to the command prompt, and

b. the PATH environment variable is a concatenation of the user and the system PATH variables.

I'm not sure what the general rule is for conflicting variables between user and system, so I elected to make user override system, except in the PATH variable which is handled specifically.

I use the weird vbs+bat+temporary bat mechanism to work around the problem of exporting variables from vbs.

Note: this script does not delete variables.

This can probably be improved.

ADDED

If you need to export the environment from one cmd window to another, use this script (let's call it exportvars.vbs):

Set oShell = WScript.CreateObject("WScript.Shell")
filename = oShell.ExpandEnvironmentStrings("%TEMP%\resetvars.bat")
Set objFileSystem = CreateObject("Scripting.fileSystemObject")
Set oFile = objFileSystem.CreateTextFile(filename, TRUE)

set oEnv=oShell.Environment("Process")
for each sitem in oEnv 
    oFile.WriteLine("SET " & sitem)
next
oFile.Close

Run exportvars.vbs in the window you want to export from, then switch to the window you want to export to, and type:

"%TEMP%\resetvars.bat"

Yes, you can do almost that:

SELECT dbo.GetBusinessDays(a.opendate,a.closedate) as BusinessDays
FROM account a
WHERE...

All the above answers are correct. Just providing with your dataset to find perfect divisor:

#include <stdio.h>

int main() 
{

int arr[7] = {3,5,7,8,9,17,19};
int j = 51;
int i = 0;

for (i=0 ; i < 7; i++) {
    if (j % arr[i] == 0)
        printf("%d is the perfect divisor of %d\n", arr[i], j);
}

return 0;
}

add:

overflow-y: scroll

in your css bud.

You could use very easily reflection to list all properties, methods and values.

For Gecko based browsers you can use the .toSource() method:

var data = new Object();
data["firstname"] = "John";
data["lastname"] = "Smith";
data["age"] = 21;

alert(data.toSource()); //Will return "({firstname:"John", lastname:"Smith", age:21})"

But since you use Firebug, why not just use console.log?

I realize this question was about creating a plugin, but since the new Jenkins 2 Pipeline builds use Groovy, I found myself here while trying to figure out how to read a file from a workspace in a Pipeline build. So maybe I can help someone like me out in the future.

Turns out it's very easy, there is a readfile step, and I should have rtfm:

env.WORKSPACE = pwd()
def version = readFile "${env.WORKSPACE}/version.txt"

Ok so in Windows sourcetree that is simple, on macOS I looked as well for a while..

Click Command + Shift + R while in source tree a hidden popup will be shown that will let you discard individual files OR ALL! Why is this hidden? We will never know.. but it works!

If you are creating a new table, you can use the inline shortcut:

  def change
    create_table :posts do |t|
      t.string :title, null: false, index: { unique: true }
      t.timestamps
    end
  end

If you installed opencv 2.4.2 then you need to change the -lopencv_core240 to -lopencv_core242

I made the same mistake.

I used this config:

<startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v2.0"/>
    <supportedRuntime version="v4.0"/>
</startup>

Worked for me

You can do what I did to inspect such problem:

Study Android source code, Paint.java source, see both measureText and getTextBounds methods. You'd learn that measureText calls native_measureText, and getTextBounds calls nativeGetStringBounds, which are native methods implemented in C++.

So you'd continue to study Paint.cpp, which implements both.

native_measureText -> SkPaintGlue::measureText_CII

nativeGetStringBounds -> SkPaintGlue::getStringBounds

Now your study checks where these methods differ. After some param checks, both call function SkPaint::measureText in Skia Lib (part of Android), but they both call different overloaded form.

Digging further into Skia, I see that both calls result into same computation in same function, only return result differently.

To answer your question: Both your calls do same computation. Possible difference of result lies in fact that getTextBounds returns bounds as integer, while measureText returns float value.

So what you get is rounding error during conversion of float to int, and this happens in Paint.cpp in SkPaintGlue::doTextBounds in call to function SkRect::roundOut.

The difference between computed width of those two calls may be maximally 1.

EDIT 4 Oct 2011

What may be better than visualization. I took the effort, for own exploring, and for deserving bounty :)

This is font size 60, in red is bounds rectangle, in purple is result of measureText.

It's seen that bounds left part starts some pixels from left, and value of measureText is incremented by this value on both left and right. This is something called Glyph's AdvanceX value. (I've discovered this in Skia sources in SkPaint.cpp)

So the outcome of the test is that measureText adds some advance value to the text on both sides, while getTextBounds computes minimal bounds where given text will fit.

Hope this result is useful to you.

Testing code:

  protected void onDraw(Canvas canvas){
     final String s = "Hello. I'm some text!";

     Paint p = new Paint();
     Rect bounds = new Rect();
     p.setTextSize(60);

     p.getTextBounds(s, 0, s.length(), bounds);
     float mt = p.measureText(s);
     int bw = bounds.width();

     Log.i("LCG", String.format(
          "measureText %f, getTextBounds %d (%s)",
          mt,
          bw, bounds.toShortString())
      );
     bounds.offset(0, -bounds.top);
     p.setStyle(Style.STROKE);
     canvas.drawColor(0xff000080);
     p.setColor(0xffff0000);
     canvas.drawRect(bounds, p);
     p.setColor(0xff00ff00);
     canvas.drawText(s, 0, bounds.bottom, p);
  }

You can get the user name using System.Security.Principal.WindowsIdentity.GetCurrent() but there is not way to get current user password!

I have JQuery UI 1.8.11 version and this is my working code. You can also customize its height and width depending on your requirements.

$("#divMain").dialog({
    modal:true,
    autoOpen: false,
    maxWidth: 500,
    maxHeight: 300,
    width: 500,
    height: 300,
    title: "Customize Dialog",
        buttons: {
            "SAVE": function () {
                //Add your functionalities here
            },
            "Cancel": function () {
                $(this).dialog("close");
            }
        },
        close: function () {}
});

I solve this problem in next way:

sudo apt-get install redis-server

then run command to confirm that everything ok:

sudo service redis-server status

And the output will be: redis-server is running - that means that the problem is solved.

I assume you are using windows. Open the command prompt and type ipconfig and find out your local address (on your pc) it should look something like 192.168.1.13 or 192.168.0.5 where the end digit is the one that changes. It should be next to IPv4 Address.

If your WAMP does not use virtual hosts the next step is to enter that IP address on your phones browser ie http://192.168.1.13 If you have a virtual host then you will need root to edit the hosts file.

If you want to test the responsiveness / mobile design of your website you can change your user agent in chrome or other browsers to mimic a mobile.

See http://googlesystem.blogspot.co.uk/2011/12/changing-user-agent-new-google-chrome.html.

Edit: Chrome dev tools now has a mobile debug tool where you can change the size of the viewport, spoof user agents, connections (4G, 3G etc).

If you get forbidden access then see this question WAMP error: Forbidden You don't have permission to access /phpmyadmin/ on this server. Basically, change the occurrances of deny,allow to allow,deny in the httpd.conf file. You can access this by the WAMP menu.

To eliminate possible causes of the issue for now set your config file to

<Directory />
    Options FollowSymLinks
    AllowOverride All
    Order allow,deny
    Allow from all
    <RequireAll>
        Require all granted
    </RequireAll>
</Directory>

As thatis working for my windows PC, if you have the directory config block as well change that also to allow all.

Config file that fixed the problem:

https://gist.github.com/samvaughton/6790739

Problem was that the /www apache directory config block still had deny set as default and only allowed from localhost.

Start in the background:

./long_running_process options &

Python 2.* ints take either 4 or 8 bytes (32 or 64 bits), depending on your Python build. sys.maxint (2**31-1 for 32-bit ints, 2**63-1 for 64-bit ints) will tell you which of the two possibilities obtains.

In Python 3, ints (like longs in Python 2) can take arbitrary sizes up to the amount of available memory; sys.getsizeof gives you a good indication for any given value, although it does also count some fixed overhead:

>>> import sys
>>> sys.getsizeof(0)
12
>>> sys.getsizeof(2**99)
28

If, as other answers suggests, you're thinking about some string representation of the integer value, then just take the len of that representation, be it in base 10 or otherwise!

It can also be as simple as this.

@media (orientation: landscape) {

}

If you're having trouble with paths you can use

require Rails.root + 'db/migrate/20090408054532_add_foos.rb'

You can specify an array in your HTML this way:

<input type="hidden" name="id[]" value="1"/>
<input type="hidden" name="id[]" value="2"/>
<input type="hidden" name="id[]" value="3"/>

This will result in this $_GET array in PHP:

array(
  'id' => array(
    0 => 1,
    1 => 2,
    2 => 3
  )
)

Of course, you can use any sort of HTML input, here. The important thing is that all inputs whose values you want in the 'id' array have the name id[].

Question: sort a string in java

I ran into this issue while opening the Service Fabric GettingStartedApplication in Visual Studio 2015. The original solution was built on .NET Core in VS 2017 and I got the same error when opening in 2015.

Here are the steps I followed to resolve the issue.

• Right click on (load Failed) project and edit in visual studio.

• Saw the following line in the Project tag: <Project Sdk="Microsoft.NET.Sdk.Web" >

• Followed the instruction shown in the error message to add xmlns="http://schemas.microsoft.com/developer/msbuild/2003" to this tag

It should now look like:

<Project Sdk="Microsoft.NET.Sdk.Web" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">

• Reloading the project gave me the next error (yours may be different based on what is included in your project)

• Saw that None element had an update attribute as below:

  <None Update="wwwroot\**\*;Views\**\*;Areas\**\Views">
    <CopyToPublishDirectory>PreserveNewest</CopyToPublishDirectory>
  </None>
  

• Commented that out as below.

  <!--<None Update="wwwroot\**\*;Views\**\*;Areas\**\Views">
    <CopyToPublishDirectory>PreserveNewest</CopyToPublishDirectory>
  </None>-->
  

• Onto the next error: Version in Package Reference is unrecognized

• Saw that Version is there in csproj xml as below (Additional PackageReference lines removed for brevity)

• Stripped the Version attribute

  <PackageReference Include="Microsoft.AspNetCore.Diagnostics" />
  <PackageReference Include="Microsoft.AspNetCore.Mvc" />
  

• I now get the following:

Bingo! The visual Studio One-way upgrade kicked in! Let VS do the magic!

• The Project loaded but with reference lib errors.

• Fixed the reference lib errors individually, by removing and replacing in NuGet to get the project working!

Hope this helps another code traveler :-D

I am a late comer to this question, but I want to mention here that the line "Program to an interface, not an implementation" had some good discussion in the GoF (Gang of Four) Design Patterns book.

It stated, on p. 18:

Program to an interface, not an implementation

Don't declare variables to be instances of particular concrete classes. Instead, commit only to an interface defined by an abstract class. You will find this to be a common theme of the design patterns in this book.

and above that, it began with:

There are two benefits to manipulating objects solely in terms of the interface defined by abstract classes:

1. Clients remain unaware of the specific types of objects they use, as long as the objects adhere to the interface that clients expect.
2. Clients remain unaware of the classes that implement these objects. Clients only know about the abstract class(es) defining the interface.

So in other words, don't write it your classes so that it has a quack() method for ducks, and then a bark() method for dogs, because they are too specific for a particular implementation of a class (or subclass). Instead, write the method using names that are general enough to be used in the base class, such as giveSound() or move(), so that they can be used for ducks, dogs, or even cars, and then the client of your classes can just say .giveSound() rather than thinking about whether to use quack() or bark() or even determine the type before issuing the correct message to be sent to the object.

For all those who came here and did indeed use Date typed Variables, here is the solution I found. It does also apply to TypeScript.

I was facing this error because I tried to compare two dates using the following Method

var res = dat1.getTime() > dat2.getTime(); // or any other comparison operator

However Im sure I used a Date object, because Im using angularjs with typescript, and I got the data from a typed API call.

Im not sure why the error is raised, but I assume that because my Object was created by JSON deserialisation, possibly the getTime() method was simply not added to the prototype.

Solution

In this case, recreating a date-Object based on your dates will fix the issue.

var res = new Date(dat1).getTime() > new Date(dat2).getTime()

Edit:

I was right about this. Types will be cast to the according type but they wont be instanciated. Hence there will be a string cast to a date, which will obviously result in a runtime exception.

The trick is, if you use interfaces with non primitive only data such as dates or functions, you will need to perform a mapping after your http request.

class Details {
    description: string;
    date: Date;
    score: number;
    approved: boolean;

    constructor(data: any) {
      Object.assign(this, data);
    }
}

and to perform the mapping:

public getDetails(id: number): Promise<Details> {
    return this.http
               .get<Details>(`${this.baseUrl}/api/details/${id}`)
               .map(response => new Details(response.json()))
               .toPromise();
}

for arrays use:

public getDetails(): Promise<Details[]> {
    return this.http
               .get<Details>(`${this.baseUrl}/api/details`)
               .map(response => {
                   const array = JSON.parse(response.json()) as any[];
                   const details = array.map(data => new Details(data));
                   return details;
               })
               .toPromise();
}

Error:Execution failed for task com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException:

One reason for this error to occure is that the file path to a resource file is to long:

Error: File path too long on Windows, keep below 240 characters 

Fix: Move your project folder closer to the root of your disk

Don't:// folder/folder/folder/folder/very_long_folder_name/MyProject...

Do://folder/short_name/MyProject

Another reason could be duplicated resources or name spaces

Example:

  <style name="MyButton" parent="android:Widget.Button">
      <item name="android:textColor">@color/accent_color</item>
      <item name="android:textColor">#000000</item>
  </style>

And make sure all file names and extensions are in lowercase

Wrong

myimage.PNG
myImage.png

Correct

my_image.png

Make sure to Clean/Rebuild project

(delete the 'build' folder)

Try that:

if(WIN32)
    set(ADDITIONAL_LIBRARIES wsock32)
else()
    set(ADDITIONAL_LIBRARIES "")
endif()

target_link_libraries(${PROJECT_NAME} bioutils ${ADDITIONAL_LIBRARIES})

You can find other useful variables here.

Declare @variable type(size);

Set @variable = 'String' or Int ;

Example:

 Declare @id int;
 set @id = 10;

 Declare @str char(50);
 set @str='Hello' ; 

ps -ef | grep KEYWORD | grep -v grep | awk '{print $2}'

Christian's answer works well and shows how you can loop through each hash table item using the GetEnumerator method. You can also loop through using the keys property. Here is an example how:

$hash = @{
    a = 1
    b = 2
    c = 3
}
$hash.Keys | % { "key = $_ , value = " + $hash.Item($_) }

Output:

key = c , value = 3
key = a , value = 1
key = b , value = 2

I put commit .gitignore, which is a courtesy to other who may build my project that the following files are derived and should be ignored.

I usually do a hybrid. I like to make makefile generate the .gitignore file since the makefile will know all the files associated with the project -derived or otherwise. Then have a top level project .gitignore that you check in, which would ignore the generated .gitignore files created by the makefile for the various sub directories.

So in my project, I might have a bin sub directory with all the built executables. Then, I'll have my makefile generate a .gitignore for that bin directory. And in the top directory .gitignore that lists bin/.gitignore. The top one is the one I check in.

I have solved this problem, please just make few changes

1- all controller class name should start with capital letter. i mean first letter of class should be capital . eg we have controler with class name Pages

so it should be Pages not pages

2- save the controller class Pages as Pages.php not pages.php

so first letter must be capital

same for model, model class first letter should be capital and also save model class as Pages_model.php not page_model.php

hope this will solve ur problem

you need to return when the readystate==4 e.g.

function httpGet(theUrl)
{
    if (window.XMLHttpRequest)
    {// code for IE7+, Firefox, Chrome, Opera, Safari
        xmlhttp=new XMLHttpRequest();
    }
    else
    {// code for IE6, IE5
        xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
    }
    xmlhttp.onreadystatechange=function()
    {
        if (xmlhttp.readyState==4 && xmlhttp.status==200)
        {
            return xmlhttp.responseText;
        }
    }
    xmlhttp.open("GET", theUrl, false );
    xmlhttp.send();    
}

Change the CorsMapping from registry.addMapping("/*") to registry.addMapping("/**") in addCorsMappings method.

Check out this Spring CORS Documentation .

From the documentation -

Enabling CORS for the whole application is as simple as:

@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {

    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**");
    }
}

You can easily change any properties, as well as only apply this CORS configuration to a specific path pattern:

@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/api/**")
            .allowedOrigins("http://domain2.com")
            .allowedMethods("PUT", "DELETE")
            .allowedHeaders("header1", "header2", "header3")
            .exposedHeaders("header1", "header2")
            .allowCredentials(false).maxAge(3600);
    }
}

Controller method CORS configuration

@RestController
@RequestMapping("/account")
public class AccountController {
  @CrossOrigin
  @RequestMapping("/{id}")
  public Account retrieve(@PathVariable Long id) {
    // ...
  }
}

To enable CORS for the whole controller -

@CrossOrigin(origins = "http://domain2.com", maxAge = 3600)
@RestController
@RequestMapping("/account")
public class AccountController {

    @RequestMapping("/{id}")
    public Account retrieve(@PathVariable Long id) {
        // ...
    }

    @RequestMapping(method = RequestMethod.DELETE, path = "/{id}")
    public void remove(@PathVariable Long id) {
        // ...
    }
}

You can even use both controller-level and method-level CORS configurations; Spring will then combine attributes from both annotations to create merged CORS configuration.

@CrossOrigin(maxAge = 3600)
@RestController
@RequestMapping("/account")
public class AccountController {

    @CrossOrigin("http://domain2.com")
    @RequestMapping("/{id}")
    public Account retrieve(@PathVariable Long id) {
        // ...
    }

    @RequestMapping(method = RequestMethod.DELETE, path = "/{id}")
    public void remove(@PathVariable Long id) {
        // ...
    }
}

Another cause of this can be including a header that depends on windows.h, before including windows.h.

In my case I included xinput.h before windows.h and got this error. Swapping the order solved the problem.

You might also take a look at the Memoize decorator. You could probably get it to do what you want without too much modification.

Change your method to look like this:

String curloc = current.toString();
String itemdesc = item.mDescription;
ArrayList<String> passing = new ArrayList<String>();
passing.add(itemdesc);
passing.add(curloc);
new calc_stanica().execute(passing); //no need to pass in result list

And change your async task implementation

public class calc_stanica extends AsyncTask<ArrayList<String>, Void, ArrayList<String>> {
ProgressDialog dialog;

    @Override
    protected void onPreExecute() {
        dialog = new ProgressDialog(baraj_mapa.this);
        dialog.setTitle("Calculating...");
        dialog.setMessage("Please wait...");
        dialog.setIndeterminate(true);
        dialog.show();
    }

    protected ArrayList<String> doInBackground(ArrayList<String>... passing) {
        ArrayList<String> result = new ArrayList<String>();
        ArrayList<String> passed = passing[0]; //get passed arraylist

        //Some calculations...

        return result; //return result
    }

    protected void onPostExecute(ArrayList<String> result) {
        dialog.dismiss();
        String minim = result.get(0);
        int min = Integer.parseInt(minim);
        String glons = result.get(1);
        String glats = result.get(2);
        double glon = Double.parseDouble(glons);
        double glat = Double.parseDouble(glats);
        GeoPoint g = new GeoPoint(glon, glat);
        String korisni_linii = result.get(3);
    }

UPD:

If you want to have access to the task starting context, the easiest way would be to override onPostExecute in place:

new calc_stanica() {
    protected void onPostExecute(ArrayList<String> result) {
      // here you have access to the context in which execute was called in first place. 
      // You'll have to mark all the local variables final though..
     }
}.execute(passing);

Have you tried JQuery? Vanilla javascript can be tough. Try using this:

$('.container-element').add('<div>Insert Div Content</div>');

.container-element is a JQuery selector that marks the element with the class "container-element" (presumably the parent element in which you want to insert your divs). Then the add() function inserts HTML into the container-element.

You can override a function using a construct like:

function override(f, g) {
    return function() {
        return g(f);
    };
}

For example:

 a = override(a, function(original_a) {
      if (condition) { new_code(); original_a(); }
      else { original_a(); other_new_code(); }
 });

Edit: Fixed a typo.

You should use the filter method rather than map unless you want to mutate the items in the array, in addition to filtering.

eg.

var filteredItems = items.filter(function(item)
{
    return ...some condition...;
});

[Edit: Of course you could always do sourceArray.filter(...).map(...) to both filter and mutate]

Combine Kim's answer with os:

p=Path(os.getcwd())
os.chdir(p.parent)

These work great for reading left / right "n" characters from a string, but, at least with BBC BASIC, the LEFT$() and RIGHT$() functions allowed you to change the left / right "n" characters too...

E.g.:

10 a$="00000"
20 RIGHT$(a$,3)="ABC"
30 PRINT a$

Would produce:

00ABC

Edit : Since writing this, I've come up with my own solution...

def left(s, amount = 1, substring = ""):
    if (substring == ""):
        return s[:amount]
    else:
        if (len(substring) > amount):
            substring = substring[:amount]
        return substring + s[:-amount]

def right(s, amount = 1, substring = ""):
    if (substring == ""):
        return s[-amount:]
    else:
        if (len(substring) > amount):
            substring = substring[:amount]
        return s[:-amount] + substring

To return n characters you'd call

substring = left(string,<n>)

Where defaults to 1 if not supplied. The same is true for right()

To change the left or right n characters of a string you'd call

newstring = left(string,<n>,substring)

This would take the first n characters of substring and overwrite the first n characters of string, returning the result in newstring. The same works for right().

There are (more than) three popular ways to use MySQL from PHP. This outlines some features/differences PHP: Choosing an API:

1. (DEPRECATED) The mysql functions are procedural and use manual escaping.
2. MySQLi is a replacement for the mysql functions, with object-oriented and procedural versions. It has support for prepared statements.
3. PDO (PHP Data Objects) is a general database abstraction layer with support for MySQL among many other databases. It provides prepared statements, and significant flexibility in how data is returned.

I would recommend using PDO with prepared statements. It is a well-designed API and will let you more easily move to another database (including any that supports ODBC) if necessary.

A key is just a normal index. A way over simplification is to think of it like a card catalog at a library. It points MySQL in the right direction.

A unique key is also used for improved searching speed, but it has the constraint that there can be no duplicated items (there are no two x and y where x is not y and x == y).

The manual explains it as follows:

A UNIQUE index creates a constraint such that all values in the index must be distinct. An error occurs if you try to add a new row with a key value that matches an existing row. This constraint does not apply to NULL values except for the BDB storage engine. For other engines, a UNIQUE index permits multiple NULL values for columns that can contain NULL. If you specify a prefix value for a column in a UNIQUE index, the column values must be unique within the prefix.

A primary key is a 'special' unique key. It basically is a unique key, except that it's used to identify something.

The manual explains how indexes are used in general: here.

In MSSQL, the concepts are similar. There are indexes, unique constraints and primary keys.

Untested, but I believe the MSSQL equivalent is:

CREATE TABLE tmp (
  id int NOT NULL PRIMARY KEY IDENTITY,
  uid varchar(255) NOT NULL CONSTRAINT uid_unique UNIQUE,
  name varchar(255) NOT NULL,
  tag int NOT NULL DEFAULT 0,
  description varchar(255),
);

CREATE INDEX idx_name ON tmp (name);
CREATE INDEX idx_tag ON tmp (tag);

Edit: the code above is tested to be correct; however, I suspect that there's a much better syntax for doing it. Been a while since I've used SQL server, and apparently I've forgotten quite a bit :).

Sssuming you have a parent Post entity and a child PostComment as illustrated in the following diagram:

If you call find when you try to set the @ManyToOne post association:

PostComment comment = new PostComment();
comment.setReview("Just awesome!");
 
Post post = entityManager.find(Post.class, 1L);
comment.setPost(post);
 
entityManager.persist(comment);

Hibernate will execute the following statements:

SELECT p.id AS id1_0_0_,
       p.title AS title2_0_0_
FROM   post p
WHERE p.id = 1
 
INSERT INTO post_comment (post_id, review, id)
VALUES (1, 'Just awesome!', 1)

The SELECT query is useless this time because we don’t need the Post entity to be fetched. We only want to set the underlying post_id Foreign Key column.

Now, if you use getReference instead:

PostComment comment = new PostComment();
comment.setReview("Just awesome!");
 
Post post = entityManager.getReference(Post.class, 1L);
comment.setPost(post);
 
entityManager.persist(comment);

This time, Hibernate will issue just the INSERT statement:

INSERT INTO post_comment (post_id, review, id)
VALUES (1, 'Just awesome!', 1)

Unlike find, the getReference only returns an entity Proxy which only has the identifier set. If you access the Proxy, the associated SQL statement will be triggered as long as the EntityManager is still open.

However, in this case, we don’t need to access the entity Proxy. We only want to propagate the Foreign Key to the underlying table record so loading a Proxy is sufficient for this use case.

When loading a Proxy, you need to be aware that a LazyInitializationException can be thrown if you try to access the Proxy reference after the EntityManager is closed.

Above accepted answer is not browser compatible. If some one has compatibility issue try this.

I did some modification to the SMNALLY's code so it can run in Python 3.5.2. This is my result:

#Import the following library to make use of the DispatchEx to run the macro
import win32com.client as wincl

def runMacro():

    if os.path.exists("C:\\Users\\Dev\\Desktop\\Development\\completed_apps\\My_Macr_Generates_Data.xlsm"):

    # DispatchEx is required in the newest versions of Python.
    excel_macro = wincl.DispatchEx("Excel.application")
    excel_path = os.path.expanduser("C:\\Users\\Dev\\Desktop\\Development\\completed_apps\\My_Macr_Generates_Data.xlsm")
    workbook = excel_macro.Workbooks.Open(Filename = excel_path, ReadOnly =1)
    excel_macro.Application.Run\
        ("ThisWorkbook.Template2G")
    #Save the results in case you have generated data
    workbook.Save()
    excel_macro.Application.Quit()  
    del excel_macro

For the first question I think answer would be:

<your DataFrame>.rename(columns={'count':'Total_Numbers'})

or

<your DataFrame>.columns = ['ID', 'Region', 'Total_Numbers']

As for second one I'd say the answer would be no. It's possible to use it like 'df.ID' because of python datamodel:

Attribute references are translated to lookups in this dictionary, e.g., m.x is equivalent to m.dict["x"]

Ok, I think I was able to find a proper solution for that.

Now, instead of sending <Link/> as prop to Document, I send <NextLink/> which is a custom wrapper for the react-router Link. By doing that, I'm able to have the right arrow as part of the Link structure while still avoiding to have routing code inside Document object.

The updated code looks like follows:

//in NextLink.js
var React = require('react');
var Right = require('./Right');

var NextLink = React.createClass({
    propTypes: {
        link: React.PropTypes.node.isRequired
    },

    contextTypes: {
        transitionTo: React.PropTypes.func.isRequired
    },

    _onClickRight: function() {
        this.context.transitionTo(this.props.link.props.to);
    },

    render: function() {
        return (
            <div>
                {this.props.link}
                <Right onClick={this._onClickRight} />
            </div>  
        );
    }
});

module.exports = NextLink;

...
//in MasterPage.js
var sampleLink = <Link to="/sample">Go To Sample</Link>
var nextLink = <NextLink link={sampleLink} />
<Document next={nextLink} />

//in Document.js
...
var Document = React.createClass({
   render: function() {
      return (
         ...
         <div>{this.props.next}</div>
         ...
      );
   }
});
...

P.S: If you are using the latest version of react-router you may need to use this.context.router.transitionTo instead of this.context.transitionTo. This code will work fine for react-router version 0.12.X.

If you use Python 2, don't forget to add the UTF-8 file encoding comment on the first line of your script.

There is also a really simple way to do this with the help of the RecursiveTreeIterator class, answered here: https://stackoverflow.com/a/37548504/2032235

The faster way for your case is:

The optimized way when one or few cell change:

    ((AbstractTableModel) jTable.getModel()).fireTableCellUpdated(x, 0); // Repaint one cell.

You can insert script to HTML like in any other (non-PHP) page, PHP processes it like any other code:

<button id="butt">
  ? Click ME! ?
</button>

<script>
    document.getElementById("butt").onclick = function () {
        alert("Message");
    }
</script>

You can use onSOMETHING attributes:

<button onclick="alert('Message')">Button</button>

To generate message in PHP, use json_encode function (it can convert to JavaScript everything that can be expressed in JSON — arrays, objects, strings, …):

<?php $message = "Your message variable"; ?>

<button onclick="alert(<?=htmlspecialchars(json_encode($message), ENT_QUOTES)?>)">Click me!</button>

If you generate code for <script> tags, do NOT use htmlspecialchars or similar function:

<?php $var = "Test string"; ?>

<button id="butt">Button</button>

<script>
    document.getElementById("butt").onclick = function () {
        alert(<?=json_encode($var)?>);
    }
</script>

You can generate whole JavaScript files, not only JavaScript embedded into HTML. You still have to name them with .php extension (like script.php). Just send the correct header.

script.php – The JavaScript file

<?php header("Content-Type: application/javascript"); /* This meant the file can be used in script tag */ ?>

<?php $var = "Message"; ?>

document.getElementById("butt").onclick = function () {
    alert(<?=json_encode($var)?>);
}

index.html – Example page that uses script.php

<!doctype html>
<html lang=en>
    <head>
        <meta charset="utf-8">
        <title>Page title</title>
    </head>
    <body>
        <button id="butt">
            BUTTON
        </button>

        <script src="script.js"></script>
    </body>
</html>

This error means Java is not properly installed .

Finally copying just means calling COPY and calling another bat file can be done like this:

The easiest way to implement the download is that you direct users to the file location, browsers will do that for you automatically.

You can easily achieve it through:

HttpServletResponse.sendRedirect()

Use a virtual environment:

$ virtualenv myenv
.. some output ..
$ source myenv/bin/activate
(myenv) $ pip install what-i-want

You only use sudo or elevated permissions when you want to install stuff for the global, system-wide Python installation.

It is best to use a virtual environment which isolates packages for you. That way you can play around without polluting the global python install.

As a bonus, virtualenv does not need elevated permissions.

It may be a little late for this question to be answered, but here is what I found.

I don't want to debate on the fact that nodes does that better than php or not, this is not the point.

The solution is : I haven't found any implementation of socket.io for PHP.

But there are some ways to implement WebSockets. There is this jQuery plugin allowing you to use Websockets while gracefully degrading for non-supporting browsers. On the PHP side, there is this class which seems to be the most widely used for PHP WS servers.

Download Json.NET from here http://james.newtonking.com/projects/json-net.aspx

& is bitwise. && is logical.

& evaluates both sides of the operation.
&& evaluates the left side of the operation, if it's true, it continues and evaluates the right side.

Another good way of dealing with Lion's hidden scroll bars is to display a prompt to scroll down. It doesn't work with small scroll areas such as text fields but well with large scroll areas and keeps the overall style of the site. One site doing this is http://versusio.com, just check this example page and wait 1.5 seconds to see the prompt:

http://versusio.com/en/samsung-galaxy-nexus-32gb-vs-apple-iphone-4s-64gb

The implementation isn't hard but you have to take care, that you don't display the prompt when the user has already scrolled.

You need jQuery + Underscore and

$(window).scroll to check if the user already scrolled by himself,

_.delay() to trigger a delay before you display the prompt -- the prompt shouldn't be to obtrusive

$('#prompt_div').fadeIn('slow') to fade in your prompt and of course

$('#prompt_div').fadeOut('slow') to fade out when the user scrolled after he saw the prompt

In addition, you can bind Google Analytics events to track user's scrolling behavior.

There are a variety of tools that you can use to help diagnose this problem. The JDK includes JVisualVM that will allow you to attach to your running process and show what objects might be growing out of control. Netbeans has a wrapper around it that works fairly well. Eclipse has the Eclipse Memory Analyzer which is the one I use most often, just seems to handle large dump files a bit better. There's also a command line option, -XX:+HeapDumpOnOutOfMemoryError that will give you a file that is basically a snapshot of your process memory when your program crashed. You can use any of the above mentioned tools to look at it, it can really help a lot when diagnosing these sort of problems.

Depending on how hard the program is working, it may be a simple case of the JVM not knowing when a good time to garbage collect may be, you might also look into the parallel garbage collection options as well.

Unlike innerText, though, innerHTML lets you work with HTML rich text and doesn't automatically encode and decode text. In other words, innerText retrieves and sets the content of the tag as plain text, whereas innerHTML retrieves and sets the content in HTML format.

from two tables with foreign key you can try this Query:

DELETE T1, T2
FROM T1
INNER JOIN T2 ON T1.key = T2.key
WHERE condition

To prevent that people are mislead by some of the comments to the other answers:

1. If .schema or query from sqlite_master not gives any output, it indicates a non-existent tablename, e.g. this may also be caused by a ; semicolon at the end for .schema, .tables, ... Or just because the table really not exists. That .schema just doesn't work is very unlikely and then a bug report should be filed at the sqlite project.

... .schema can only be used from a command line; the above commands > can be run as a query through a library (Python, C#, etc.). – Mark Rushakoff Jul 25 '10 at 21:09

2. 'can only be used from a command line' may mislead people. Almost any (likely every?) programming language can call other programs/commands. Therefore the quoted comment is unlucky as calling another program, in this case sqlite, is more likely to be supported than that the language provides a wrapper/library for every program (which not only is prone to incompleteness by the very nature of the masses of programs out there, but also is counter acting single-source principle, complicating maintenance, furthering the chaos of data in the world).

These are utf-8 encoded characters. Use utf8_decode() to convert them to normal ISO-8859-1 characters.

I was getting this problem and I'm using Spring's RestTemplate on the client and Spring Web on the server. Both APIs have very poor error reporting, making them extremely difficult to develop with.

After many hours of trying all sorts of experiments I figured out that the issue was being caused by passing in a null reference for the POST body instead of the expected List. I presume that RestTemplate cannot determine the content-type from a null object, but doesn't complain about it. After adding the correct headers, I started getting a different server-side exception in Spring before entering my service method.

The fix was to pass in an empty List from the client instead of null. No headers are required since the default content-type is used for non-null objects.

If you like to use Jackson Databind (which Spring uses by default for its HttpMessageConverters), then you may use the ObjectMapper.readTree(InputStream) API. For example,

ObjectMapper mapper = new ObjectMapper();
JsonNode json = mapper.readTree(myInputStream);

I used the code below, and it works

'PHONE' => 'required|regex:/(0)[0-9]/|not_regex:/[a-z]/|min:9',

Just came across this googling for a solution. Actually, there is one in Ansible 2.5. You can specify your inventory file with --inventory, like this: ansible --inventory configs/hosts --list-hosts all

>>> k = [[1, 2], [4], [5, 6, 2], [1, 2], [3], [4]]
>>> k = sorted(k)
>>> k
[[1, 2], [1, 2], [3], [4], [4], [5, 6, 2]]
>>> dedup = [k[i] for i in range(len(k)) if i == 0 or k[i] != k[i-1]]
>>> dedup
[[1, 2], [3], [4], [5, 6, 2]]

I don't know if it's necessarily faster, but you don't have to use to tuples and sets.

Change the submit button to:

<button type="submit" ng-disabled="loginform.$invalid">Login</button>

copying the jar files will resolve. If by any chance you are copying the code from any tutorials, make sure the class names are spelled in correct case...for example i copied a code from one of the tutorials which had solr in S cap. Eclipse was continiously throwing the error and i also did a bit of googling ...everything was ok and it took 30 mins for me to realise the cap small issue. Am sure this will help someone

It is little tricky when you try to combine optional parameter and default value for that parameter. Like this,

func test(param: Int? = nil)

These two are completely opposite ideas. When you have an optional type parameter but you also provide default value to it, it is no more an optional type now since it has a default value. Even if the default is nil, swift simply removes the optional binding without checking what the default value is.

So it is always better not to use nil as default value.

Merged Chuck Norris's answer w/ Paulo Mendonça's using extensions methods:

/// <summary>
/// Replace a string char at index with another char
/// </summary>
/// <param name="text">string to be replaced</param>
/// <param name="index">position of the char to be replaced</param>
/// <param name="c">replacement char</param>
public static string ReplaceAtIndex(this string text, int index, char c)
{
    var stringBuilder = new StringBuilder(text);
    stringBuilder[index] = c;
    return stringBuilder.ToString();
}

$("input").prop('required',true);

An even simpler solution to the above:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true">
        <color android:color="@color/semitransparent_white" />
    </item>
    <item>
        <color android:color="@color/transparent" />
    </item>
</selector>

Save that in the drawable folder and you're good to go.

As soon as a WHEN statement is true the break is implicit.

You will have to concider which WHEN Expression is the most likely to happen. If you put that WHEN at the end of a long list of WHEN statements, your sql is likely to be slower. So put it up front as the first.

More information here: break in case statement in T-SQL

Here is a function that does this:

function days_between(date1, date2) {

    // The number of milliseconds in one day
    const ONE_DAY = 1000 * 60 * 60 * 24;

    // Calculate the difference in milliseconds
    const differenceMs = Math.abs(date1 - date2);

    // Convert back to days and return
    return Math.round(differenceMs / ONE_DAY);

}

The HTML tags that you want to edit is called the DOM (Document object manipulate), you can edit the DOM with many functions in the document global object.

The best example that would work on almost any browser is the document.getElementById, it's search for html tag with that id set as an attribute.

There is another option which is easier but works only on modern browsers (IE8+), the querySelector function, it's will find the first element with the matched selector (CSS selectors).

Examples for both options:

<script>_x000D_
var name = prompt("What's your name?");_x000D_
var lengthOfName = name.length_x000D_
</script>_x000D_
<body>_x000D_
  <p id="a"></p>_x000D_
  <p id="b"></p>_x000D_
  <script>_x000D_
    document.getElementById('a').innerHTML = name;_x000D_
document.querySelector('#b').innerHTML = name.length;</script>_x000D_
</body>

Not sure what you call FIFO these days since Queue is FILO, but when I was a student we used the Stack<E> with the simple push, pop, and a peek... It is really that simple, no need for complicating further with Queue and whatever the accepted answer suggests.

From official reference

Full-text indexes can be used only with MyISAM tables. (In MySQL 5.6 and up, they can also be used with InnoDB tables.) Full-text indexes can be created only for CHAR, VARCHAR, or TEXT columns.

https://dev.mysql.com/doc/refman/5.5/en/fulltext-search.html

InnoDB with MySQL 5.5 does not support Full-text indexes.

You can easily mock an extension method with JustMock. The API is the same as mocking normal method. Consider the following

public static string Echo(this Foo foo, string strValue) 
{ 
    return strValue; 
}

To arrange and verify this method use the following:

string expected = "World";

var foo = new Foo();
Mock.Arrange(() => foo.Echo(Arg.IsAny<string>())).Returns(expected);

string result = foo.Echo("Hello");

Assert.AreEqual(expected, result);

Here is also a link to the documentation: Extension Methods Mocking

Disclaimer. I am one of the developers responsible for JustMock.

I'm using the solution provided by Arunakiran Nulu in my analysis (see the code). Despite it is able to assign the correct types to the columns, all the values returned are null. Previously, I've tried to the option .option("inferSchema", "true") and it returns the correct values in the dataframe (although different type).

val customSchema = StructType(Array(
    StructField("numicu", StringType, true),
    StructField("fecha_solicitud", TimestampType, true),
    StructField("codtecnica", StringType, true),
    StructField("tecnica", StringType, true),
    StructField("finexploracion", TimestampType, true),
    StructField("ultimavalidacioninforme", TimestampType, true),
    StructField("validador", StringType, true)))

val df_explo = spark.read
        .format("csv")
        .option("header", "true")
        .option("delimiter", "\t")
        .option("timestampFormat", "yyyy/MM/dd HH:mm:ss") 
        .schema(customSchema)
        .load(filename)

The following steps are to reset the password for a user in case you forgot, this would also solve your mentioned error.

First, stop your MySQL:

sudo /etc/init.d/mysql stop

Now start up MySQL in safe mode and skip the privileges table:

sudo mysqld_safe --skip-grant-tables &

Login with root:

mysql -uroot

And assign the DB that needs to be used:

use mysql;

Now all you have to do is reset your root password of the MySQL user and restart the MySQL service:

update user set password=PASSWORD("YOURPASSWORDHERE") where User='root';

flush privileges;

quit and restart MySQL:

quit

sudo /etc/init.d/mysql stop sudo /etc/init.d/mysql start Now your root password should be working with the one you just set, check it with:

mysql -u root -p

One cheeky solution :

  function printDiv(divID) {
        //Get the HTML of div
        var divElements = document.getElementById(divID).innerHTML;
        //Get the HTML of whole page
        var oldPage = document.body.innerHTML;
        //Reset the page's HTML with div's HTML only
        document.body.innerHTML = 
          "<html><head><title></title></head><body>" + 
          divElements + "</body>";
        //Print Page
        window.print();
        //Restore orignal HTML
        document.body.innerHTML = oldPage;

    }

HTML :

<form id="form1" runat="server">
    <div id="printablediv" style="width: 100%; background-color: Blue; height: 200px">
        Print me I am in 1st Div
    </div>
    <div id="donotprintdiv" style="width: 100%; background-color: Gray; height: 200px">
        I am not going to print
    </div>
    <input type="button" value="Print 1st Div" onclick="javascript:printDiv('printablediv')" />
</form>

I'm using this technique to keep the logo as responsive for mobile devices as a simple way. The logo will resize automatically.

Expanding from Andriy M, and yes you can do this from a file, even one with multiple lines

@echo off
setlocal EnableExtensions EnableDelayedExpansion
set "INTEXTFILE=test.txt"
set "OUTTEXTFILE=test_out.txt"
set "SEARCHTEXT=bath"
set "REPLACETEXT=hello"

for /f "delims=" %%A in ('type "%INTEXTFILE%"') do (
    set "string=%%A"
    set "modified=!string:%SEARCHTEXT%=%REPLACETEXT%!"
    echo !modified!>>"%OUTTEXTFILE%"
)

del "%INTEXTFILE%"
rename "%OUTTEXTFILE%" "%INTEXTFILE%"
endlocal

EDIT

Thanks David Nelson, I have updated the script so it doesn't have the hard coded values anymore.

$year = date("Y");   
$month = date("m");   
$filename = "../".$year;   
$filename2 = "../".$year."/".$month;

if(file_exists($filename)){
    if(file_exists($filename2)==false){
        mkdir($filename2,0777);
    }
}else{
    mkdir($filename,0777);
}

If your text is: Joe said, "Fred was here with his "Wife"".
This is saved in a CSV as:
"Joe said, ""Fred was here with his ""Wife""""."
(Rule is double quotes go around the whole field, and double quotes are converted to two double quotes). So a simple Optionally Enclosed By clause is needed but not sufficient. CSVs are tough due to this rule. You can sometimes use a Replace clause in the loader for that field but depending on your data this may not be enough. Often pre-processing of a CSV is needed to load in Oracle. Or save it as an XLS and use Oracle SQL Developer app to import to the table - great for one-time work, not so good for scripting.

As @jethro said, splitext is the neat way to do it. But in this case, it's pretty easy to split it yourself, since the extension must be the part of the filename coming after the final period:

filename = '/home/user/somefile.txt'
print( filename.rsplit( ".", 1 )[ 0 ] )
# '/home/user/somefile'

The rsplit tells Python to perform the string splits starting from the right of the string, and the 1 says to perform at most one split (so that e.g. 'foo.bar.baz' -> [ 'foo.bar', 'baz' ]). Since rsplit will always return a non-empty array, we may safely index 0 into it to get the filename minus the extension.

You could take the average buffer gets per execution during a period of activity of the instance:

SELECT username,
       buffer_gets,
       disk_reads,
       executions,
       buffer_get_per_exec,
       parse_calls,
       sorts,
       rows_processed,
       hit_ratio,
       module,
       sql_text
       -- elapsed_time, cpu_time, user_io_wait_time, ,
  FROM (SELECT sql_text,
               b.username,
               a.disk_reads,
               a.buffer_gets,
               trunc(a.buffer_gets / a.executions) buffer_get_per_exec,
               a.parse_calls,
               a.sorts,
               a.executions,
               a.rows_processed,
               100 - ROUND (100 * a.disk_reads / a.buffer_gets, 2) hit_ratio,
               module
               -- cpu_time, elapsed_time, user_io_wait_time
          FROM v$sqlarea a, dba_users b
         WHERE a.parsing_user_id = b.user_id
           AND b.username NOT IN ('SYS', 'SYSTEM', 'RMAN','SYSMAN')
           AND a.buffer_gets > 10000
         ORDER BY buffer_get_per_exec DESC)
 WHERE ROWNUM <= 20

Left joins in LINQ are possible with the DefaultIfEmpty() method. I don't have the exact syntax for your case though...

Actually I think if you just change pets to pets.DefaultIfEmpty() in the query it might work...

EDIT: I really shouldn't answer things when its late...

It's as simple as the one below, and works like a charm.

My solution perfectly answers your question: How to make JQuery-AJAX request synchronous

Set ajax to synchronous before the ajax call, and then reset it after your ajax call:

$.ajaxSetup({async: false});

$ajax({ajax call....});

$.ajaxSetup({async: true});

In your case it would look like this:

$.ajaxSetup({async: false});

$.ajax({
        type: "POST",
        async: "false",
        url: "checkpass.php",
        data: "password="+password,
        success: function(html) {
            var arr=$.parseJSON(html);
            if(arr == "Successful") {
                return true;
            } else {
                return false;
            }
        }
    });


$.ajaxSetup({async: true});

I hope it helps :)

You shouldn't design your application based on specific lifetimes of access tokens. Just assume they are (very) short lived.

However, after a successful completion of the OAuth2 installed application flow, you will get back a refresh token. This refresh token never expires, and you can use it to exchange it for an access token as needed. Save the refresh tokens, and use them to get access tokens on-demand (which should then immediately be used to get access to user data).

EDIT: My comments above notwithstanding, there are two easy ways to get the access token expiration time:

1. It is a parameter in the response (expires_in)when you exchange your refresh token (using /o/oauth2/token endpoint). More details.

2. There is also an API that returns the remaining lifetime of the access_token:

   https://www.googleapis.com/oauth2/v1/tokeninfo?access_token={accessToken}

   This will return a json array that will contain an expires_in parameter, which is the number of seconds left in the lifetime of the token.

Calling function f with named parameters passed as the object

o = {height: 1, width: 5, ...}

is basically calling its composition f(...g(o)) where I am using the spread syntax and g is a "binding" map connecting the object values with their parameter positions.

The binding map is precisely the missing ingredient, that can be represented by the array of its keys:

// map 'height' to the first and 'width' to the second param
binding = ['height', 'width']

// take binding and arg object and return aray of args
withNamed = (bnd, o) => bnd.map(param => o[param])

// call f with named args via binding
f(...withNamed(binding, {hight: 1, width: 5}))

Note the three decoupled ingredients: the function, the object with named arguments and the binding. This decoupling allows for a lot of flexibility to use this construct, where the binding can be arbitrarily customized in function's definition and arbitrarily extended at the function call time.

For instance, you may want to abbreviate height and width as h and w inside your function's definition, to make it shorter and cleaner, while you still want to call it with full names for clarity:

// use short params
f = (h, w) => ...

// modify f to be called with named args
ff = o => f(...withNamed(['height', 'width'], o))

// now call with real more descriptive names
ff({height: 1, width: 5})

This flexibility is also more useful for functional programming, where functions can be arbitrarily transformed with their original param names getting lost.

I use mobile = /Android|webOS|iPhone|iPad|iPod|BlackBerry/i.test(navigator.userAgent)

Here is the right way to do imports in Java.

import Dan.Vik;
class Kab
{
public static void main(String args[])
{
    Vik Sam = new Vik();
    Sam.disp();
}
}

You don't import methods in java. There is an advanced usage of static imports but basically you just import packages and classes. If the function you are importing is a static function you can do a static import, but I don't think you are looking for static imports here.

If you use Tomcat, add '-Dorg.apache.tomcat.util.buf.UDecoder.ALLOW_ENCODED_SLASH=true' in VM properties.

https://tomcat.apache.org/tomcat-7.0-doc/config/systemprops.html#Security

with small numbers of points you could run a simulation:

from random import random,randint
r = 10
n = 20
best_closest_d = 0
best_points = []
points = [(r,0,0) for i in range(n)]
for simulation in range(10000):
    x = random()*r
    y = random()*r
    z = r-(x**2+y**2)**0.5
    if randint(0,1):
        x = -x
    if randint(0,1):
        y = -y
    if randint(0,1):
        z = -z
    closest_dist = (2*r)**2
    closest_index = None
    for i in range(n):
        for j in range(n):
            if i==j:
                continue
            p1,p2 = points[i],points[j]
            x1,y1,z1 = p1
            x2,y2,z2 = p2
            d = (x1-x2)**2+(y1-y2)**2+(z1-z2)**2
            if d < closest_dist:
                closest_dist = d
                closest_index = i
    if simulation % 100 == 0:
        print simulation,closest_dist
    if closest_dist > best_closest_d:
        best_closest_d = closest_dist
        best_points = points[:]
    points[closest_index]=(x,y,z)


print best_points

@The Thunder Chimp You can split text in such a way that some sections are affected by super(or sub) script and others aren't through the use of *. For your example, with splitting the word "moment" from "4th" -

plot(rnorm(30), xlab = expression('4'^th*'moment'))

If you are using jQuery you can use the extend function to add new items.

var olddata = {"fruit":{"apples":10,"pears":21}};

var newdata = {};
newdata['vegetables'] = {"carrots": 2, "potatoes" : 5};

$.extend(true, olddata, newdata);

This will generate:

{"fruit":{"apples":10,"pears":21}, "vegetables":{"carrots":2,"potatoes":5}};

Write Thread.sleep(1000); it will make the thread sleep for 1000ms

just override the method:

- (void)scrollViewWillEndDragging:(UIScrollView *)scrollView withVelocity:(CGPoint)velocity targetContentOffset:(inout CGPoint *)targetContentOffset {
    *targetContentOffset = scrollView.contentOffset; // set acceleration to 0.0
    float pageWidth = (float)self.articlesCollectionView.bounds.size.width;
    int minSpace = 10;

    int cellToSwipe = (scrollView.contentOffset.x)/(pageWidth + minSpace) + 0.5; // cell width + min spacing for lines
    if (cellToSwipe < 0) {
        cellToSwipe = 0;
    } else if (cellToSwipe >= self.articles.count) {
        cellToSwipe = self.articles.count - 1;
    }
    [self.articlesCollectionView scrollToItemAtIndexPath:[NSIndexPath indexPathForRow:cellToSwipe inSection:0] atScrollPosition:UICollectionViewScrollPositionLeft animated:YES];
}

From the documentation of InetAddress.getByName(String host):

The host name can either be a machine name, such as "java.sun.com", or a textual representation of its IP address. If a literal IP address is supplied, only the validity of the address format is checked.

So you can use it.

You shouldn't need to let the users specify the margin on your website - Let them do it on their computer. Print dialogs usually (Adobe and Preview, at least) give you an option to scale and center the output on the printable area of the page:

Adobe

Preview

Of course, this assumes that you have computer literate users, which may or may not be the case.

create resource file in drawable

This is because label is an inline element, and is therefore only as big as the text it contains.

The possible is to display your label as a block element like this:

#formItem label {
    display: block;
    text-align: center;
    line-height: 150%;
    font-size: .85em;
}

However, if you want to use the label on the same line with other elements, you either need to set display: inline-block; and give it an explicit width (which doesn't work on most browsers), or you need to wrap it inside a div and do the alignment in the div.

A bit late for this, but this thread comes up in Google as a top result when searching for an overlay method.

You could simply use a background-blend-mode

.foo {
    background-image: url(images/image1.png), url(images/image2.png);
    background-color: violet;
    background-blend-mode: screen multiply;
}

What this does is it takes the second image, and it blends it with the background colour by using the multiply blend mode, and then it blends the first image with the second image and the background colour by using the screen blend mode. There are 16 different blend modes that you could use to achieve any overlay.

multiply, screen, overlay, darken, lighten, color-dodge, color-burn, hard-light, soft-light, difference, exclusion, hue, saturation, color and luminosity.

You should use something like this:

SELECT *
FROM (select salary2.*, rownum rnum from
         (select * from salary ORDER BY salary_amount DESC) salary2
  where rownum <= 2 )
WHERE rnum >= 2;

1) local simplest methods

<?php
echo readfile("http://example.com/");   //needs "Allow_url_include" enabled
//OR
echo include("http://example.com/");    //needs "Allow_url_include" enabled
//OR
echo file_get_contents("http://example.com/");
//OR
echo stream_get_contents(fopen('http://example.com/', "rb")); //you may use "r" instead of "rb"  //needs "Allow_url_fopen" enabled
?> 

2) Better Way is CURL:

echo get_remote_data('http://example.com'); // GET request 
echo get_remote_data('http://example.com', "var2=something&var3=blabla" ); // POST request

It automatically handles FOLLOWLOCATION problem + Remote urls:
src="./imageblabla.png" turned into:
src="http://example.com/path/imageblabla.png"

Code : https://github.com/tazotodua/useful-php-scripts/blob/master/get-remote-url-content-data.php

You need to include the appropriate header

#include <stdio.h>

If you're not sure which header a standard function is defined in, the function's man page will state this.

Create the file! try:

mkdir -p .android && touch ~/.android/repositories.cfg

Use Integer.parseInt (see javadoc), that converts your String to int using base two:

int decimalValue = Integer.parseInt(c, 2);

For me perfectly fork this code.

$('#dom_object_id').on('change paste keyup', function(){
    console.log($("#dom_object_id").val().length)
});

Key event for .on() function is "paste" to get changes dynamically

window.location = myUrl;

Anyway, this is not jQuery: it's plain javascript

Petar Ivanov's answer to replace a character at a specific index in a string question

String are immutable in Java. You can't change them.

You need to create a new string with the character replaced.

String myName = "domanokz";
String newName = myName.substring(0,4)+'x'+myName.substring(5);

Or you can use a StringBuilder:

StringBuilder myName = new StringBuilder("domanokz");
myName.setCharAt(4, 'x');

System.out.println(myName);

There are two type of paths: absolute and relative. This is basically the same for files in your hard disc and directories in a URL.

Absolute paths start with a leading slash. They always point to the same location, no matter where you use them:

• /pages/en/faqs/faq-page1.html

Relative paths are the rest (all that do not start with slash). The location they point to depends on where you are using them

• index.html is:
  • /pages/en/faqs/index.html if called from /pages/en/faqs/faq-page1.html
  • /pages/index.html if called from /pages/example.html
  • etc.

There are also two special directory names: . and ..:

• . means "current directory"
• .. means "parent directory"

You can use them to build relative paths:

• ../index.html is /pages/en/index.html if called from /pages/en/faqs/faq-page1.html
• ../../index.html is /pages/index.html if called from /pages/en/faqs/faq-page1.html

Once you're familiar with the terms, it's easy to understand what it's failing and how to fix it. You have two options:

• Use absolute paths
• Fix your relative paths

You can add a DLL (or EXE) to a project only if it is a .NET assembly. If it's not you will see this error message.

regsvr32 also makes certain assumptions about the structure and exported function in the DLL. It has been a while since I used it but it has to do with registering COM servers so certain entry points need to be available. If regsvr32 fails the DLL doesn't provide those entry points and the DLL does not contain a COM component.

You only chance for using the DLL is to import it like any other non-.NET binary, e.g. when you use certain Win32 APIs. There is an old MSDN Magazine Article that might be helpful. See the following update for info where to get the article.

Update 12 March 2018: The link to the MSDN Magazine no longer works as it used to in August 2010. The article by Jason Clark is titled ".NET Column: Calling Win32 DLLs in C# with P/Invoke". It was published in the July 2010 issue of MSDN Magazine. The "Wayback Machine" has the article here at the moment (formatting is limited). The entire MSDN Magazine issue July 2010 is available here (HCM format only, instructions for how to use HCM files here).

You can try OleDB to read data from excel file. Please try as follow..

DataSet ds_Data = new DataSet();
OleDbConnection oleCon = new OleDbConnection();

oleCon.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + strExcelFile + ";Extended Properties=\"Excel 12.0;IMEX=1;HDR=NO;TypeGuessRows=0;ImportMixedTypes=Text\"";;

 string SpreadSheetName = "";

OleDbDataAdapter Adapter = new OleDbDataAdapter();
OleDbConnection conn = new OleDbConnection(sConnectionString);

string strQuery;
conn.Open();

int workSheetNumber = 0;

DataTable ExcelSheets = conn.GetOleDbSchemaTable(System.Data.OleDb.OleDbSchemaGuid.Tables, new object[] { null, null, null, "TABLE" });

SpreadSheetName = ExcelSheets.Rows[workSheetNumber]["TABLE_NAME"].ToString();

strQuery = "select * from [" + SpreadSheetName + "] ";
OleDbCommand cmd = new OleDbCommand(strQuery, conn);
Adapter.SelectCommand = cmd;
DataSet dsExcel = new DataSet();
Adapter.Fill(dsExcel);
conn.Close();

Look into:

mysql_query('DESCRIBE '.$table);

When the directory is deleted, the inode for that directory (and the inodes for its contents) are recycled. The pointer your shell has to that directory's inode (and its contents's inodes) are now no longer valid. When the directory is restored from backup, the old inodes are not (necessarily) reused; the directory and its contents are stored on random inodes. The only thing that stays the same is that the parent directory reuses the same name for the restored directory (because you told it to).

Now if you attempt to access the contents of the directory that your original shell is still pointing to, it communicates that request to the file system as a request for the original inode, which has since been recycled (and may even be in use for something entirely different now). So you get a stale file handle message because you asked for some nonexistent data.

When you perform a cd operation, the shell reevaluates the inode location of whatever destination you give it. Now that your shell knows the new inode for the directory (and the new inodes for its contents), future requests for its contents will be valid.

A good practice can be found here:

There are two simple methods for creating laravel Project

Method 1

composer create-project --prefer-dist laravel/laravel <project-name>

Method 2

laravel new <project-name>

Method 2 might require you to run one extra command

composer global require laravel/installer

if you face 'laravel command not found' error

Let's consider a system where each user is linked to one or more roles and each role is linked to one or more access privileges. This information can be cached for better API performance. But then, there may be changes in the user and role configurations (for e.g. new access may be granted or current access may be revoked) and these should be reflected in the cache.

We can use access and refresh tokens for such purpose. When an API is invoked with access token, the resource server checks the cache for access rights. IF there is any new access grants, it is not reflected immediately. Once the access token expires (say in 30 minutes) and the client uses the refresh token to generate a new access token, the cache can be updated with the updated user access right information from the DB.

In other words, we can move the expensive operations from every API call using access tokens to the event of access token generation using refresh token.

Try command + t. It works for me.

I'm not sure at what level you're asking this question. It sounds as if you've found the formulas online, and are just trying to understand what it does. On that reading of your question I offer:

• Imagine a ray from the viewer (at point V) directly towards the center of the projection plane (call it C).
• Imagine a second ray from the viewer to a point in the image (P) which also intersects the projection plane at some point (Q)
• The viewer and the two points of intersection on the view plane form a triangle (VCQ); the sides are the two rays and the line between the points in the plane.
• The formulas are using this triangle to find the coordinates of Q, which is where the projected pixel will go

As others have suggested that you should look into MERGE statement but nobody provided a solution using it I'm adding my own answer with this particular TSQL construct. I bet you'll like it.

Important note

Your code has a typo in your if statement in not exists(select...) part. Inner select statement has only one where condition while UserName condition is excluded from the not exists due to invalid brace completion. In any case you cave too many closing braces.

I assume this based on the fact that you're using two where conditions in update statement later on in your code.

Let's continue to my answer...

SQL Server 2008+ support MERGE statement

MERGE statement is a beautiful TSQL gem very well suited for "insert or update" situations. In your case it would look similar to the following code. Take into consideration that I'm declaring variables what are likely stored procedure parameters (I suspect).

declare @clockDate date = '08/10/2012';
declare @userName = 'test';

merge Clock as target
using (select @clockDate, @userName) as source (ClockDate, UserName)
on (target.ClockDate = source.ClockDate and target.UserName = source.UserName)
when matched then
    update
    set BreakOut = getdate()
when not matched then
    insert (ClockDate, UserName, BreakOut)
    values (getdate(), source.UserName, getdate());

You can use the ast module and write a NodeVisitor that verifies that the type of each node is part of a whitelist.

import ast, math

locals =  {key: value for (key,value) in vars(math).items() if key[0] != '_'}
locals.update({"abs": abs, "complex": complex, "min": min, "max": max, "pow": pow, "round": round})

class Visitor(ast.NodeVisitor):
    def visit(self, node):
       if not isinstance(node, self.whitelist):
           raise ValueError(node)
       return super().visit(node)

    whitelist = (ast.Module, ast.Expr, ast.Load, ast.Expression, ast.Add, ast.Sub, ast.UnaryOp, ast.Num, ast.BinOp,
            ast.Mult, ast.Div, ast.Pow, ast.BitOr, ast.BitAnd, ast.BitXor, ast.USub, ast.UAdd, ast.FloorDiv, ast.Mod,
            ast.LShift, ast.RShift, ast.Invert, ast.Call, ast.Name)

def evaluate(expr, locals = {}):
    if any(elem in expr for elem in '\n#') : raise ValueError(expr)
    try:
        node = ast.parse(expr.strip(), mode='eval')
        Visitor().visit(node)
        return eval(compile(node, "<string>", "eval"), {'__builtins__': None}, locals)
    except Exception: raise ValueError(expr)

Because it works via a whitelist rather than a blacklist, it is safe. The only functions and variables it can access are those you explicitly give it access to. I populated a dict with math-related functions so you can easily provide access to those if you want, but you have to explicitly use it.

If the string attempts to call functions that haven't been provided, or invoke any methods, an exception will be raised, and it will not be executed.

Because this uses Python's built in parser and evaluator, it also inherits Python's precedence and promotion rules as well.

>>> evaluate("7 + 9 * (2 << 2)")
79
>>> evaluate("6 // 2 + 0.0")
3.0

The above code has only been tested on Python 3.

If desired, you can add a timeout decorator on this function.

A space may only be encoded to "+" in the "application/x-www-form-urlencoded" content-type key-value pairs query part of an URL. In my opinion, this is a MAY, not a MUST. In the rest of URLs, it is encoded as %20.

In my opinion, it's better to always encode spaces as %20, not as "+", even in the query part of an URL, because it is the HTML specification (RFC-1866) that specified that space characters should be encoded as "+" in "application/x-www-form-urlencoded" content-type key-value pairs (see paragraph 8.2.1. subparagraph 1.)

This way of encoding form data is also given in later HTML specifications. For example, look for relevant paragraphs about application/x-www-form-urlencoded in HTML 4.01 Specification, and so on.

Here is a sample string in URL where the HTML specification allows encoding spaces as pluses: "http://example.com/over/there?name=foo+bar". So, only after "?", spaces can be replaced by pluses. In other cases, spaces should be encoded to %20. But since it's hard to correctly determine the context, it's the best practice to never encode spaces as "+".

I would recommend to percent-encode all character except "unreserved" defined in RFC-3986, p.2.3

unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"

The implementation depends on the programming language that you chose.

If your URL contains national characters, first encode them to UTF-8 and then percent-encode the result.

Use brackets to group the OR statements.

mysql_query("SELECT * FROM Drinks WHERE email='$Email' AND (date='$Date_Today' OR date='$Date_Yesterday' OR date='$Date_TwoDaysAgo' OR date='$Date_ThreeDaysAgo' OR date='$Date_FourDaysAgo' OR date='$Date_FiveDaysAgo' OR date='$Date_SixDaysAgo' OR date='$Date_SevenDaysAgo')");

You can also use IN

mysql_query("SELECT * FROM Drinks WHERE email='$Email' AND date IN ('$Date_Today','$Date_Yesterday','$Date_TwoDaysAgo','$Date_ThreeDaysAgo','$Date_FourDaysAgo','$Date_FiveDaysAgo','$Date_SixDaysAgo','$Date_SevenDaysAgo')");

You need to pass an array of element to jsx. The problem is that forEach does not return anything (i.e it returns undefined). So it's better to use map because map returns an array:

class QuestionSet extends Component {
render(){ 
    <div className="container">
       <h1>{this.props.question.text}</h1>
       {this.props.question.answers.map((answer, i) => {     
           console.log("Entered");                 
           // Return the element. Also pass key     
           return (<Answer key={answer} answer={answer} />) 
        })}
}

export default QuestionSet;

Correct answer is:

$.each(lines, function(lineNo, line) {
                    var items = line.split(',');
                    var data = {};
                    $.each(items, function(itemNo, item) {
                        if (itemNo === 0) {
                            data.name = item;
                        } else {
                            data.y = parseFloat(item);
                        }
                    });
                    options.series[0].data.push(data);
                    data = {};
                });

You need to flush the 'data' array.

data = {};

For Linux and MacOS users :

1. First make the repository (Name=RepositoryName) on github.
2. Open the terminal and make the new directory (mkdir NewDirectory).
3. Copy your ProjectFolder to this NewDirectory.
4. Change the present work directory to NewDirectory.
5. Run these commands
   1. git init
   2. git add ProjectFolderName
   3. git commit -m "first commit"
   4. git remote add origin https://github.com/YourGithubUsername/RepositoryName.git
   5. git push -u origin master

For Dot Net Core 3, Microsoft.Data.SqlClient should be used.

The below code doesn't return the correct screen size sometimes:

MediaQuery.of(context).size

I tested on SAMSUNG SM-T580, which returns {width: 685.7, height: 1097.1} instead of the real resolution 1920x1080.

Please use:

import 'dart:ui';

window.physicalSize;

One possible way is to use .map() method:

var all = $(".mbox").map(function() {
    return this.innerHTML;
}).get();

console.log(all.join());

DEMO: http://jsfiddle.net/Y4bHh/

N.B. Please don't use document.write. For testing purposes console.log is the best way to go.

In case you're inside a Sub of Function and you want to exit it, you can use :

Exit Sub

or

Exit Function 

You also need to include the Log4J JAR file in the classpath.

Note that slf4j-log4j12-1.6.4.jar is only an adapter to make it possible to use Log4J via the SLF4J API. It does not contain the actual implementation of Log4J.

I had the same issue. Thanks for the answers above, I solved my issue. If there are people facing the same problem, here is two way to solve it:

• You can use {!! $news->body !!}
• You can use traditional php openning (It is not recommended) like: <?php echo $string ?>

I hope it helps.

std based

#include <iostream>
#include <iomanip>
#include <sstream>
#include <string>

using namespace std;

#include <openssl/sha.h>
string sha256(const string str)
{
    unsigned char hash[SHA256_DIGEST_LENGTH];
    SHA256_CTX sha256;
    SHA256_Init(&sha256);
    SHA256_Update(&sha256, str.c_str(), str.size());
    SHA256_Final(hash, &sha256);
    stringstream ss;
    for(int i = 0; i < SHA256_DIGEST_LENGTH; i++)
    {
        ss << hex << setw(2) << setfill('0') << (int)hash[i];
    }
    return ss.str();
}

int main() {
    cout << sha256("1234567890_1") << endl;
    cout << sha256("1234567890_2") << endl;
    cout << sha256("1234567890_3") << endl;
    cout << sha256("1234567890_4") << endl;
    return 0;
}

After Xcode 6.1 Beta the code below works, slight edit on Tom S code that stopped working with the 6.1 beta (worked with previous beta):

   if UIApplication.sharedApplication().respondsToSelector("registerUserNotificationSettings:") {
        // It's iOS 8
        var types = UIUserNotificationType.Badge | UIUserNotificationType.Sound | UIUserNotificationType.Alert
       var settings = UIUserNotificationSettings(forTypes: types, categories: nil)
       UIApplication.sharedApplication().registerUserNotificationSettings(settings)
    } else {
        // It's older
        var types = UIRemoteNotificationType.Badge | UIRemoteNotificationType.Sound | UIRemoteNotificationType.Alert
        UIApplication.sharedApplication().registerForRemoteNotificationTypes(types)
    }

There is no hard and fast rule.

Here are some rules to make code thread safe in .NET and why these are not good rules:

1. Function and all functions it calls must be pure (no side effects) and use local variables. Although this will make your code thread-safe, there is also very little amount of interesting things you can do with this restriction in .NET.
2. Every function that operates on a common object must lock on a common thing. All locks must be done in same order. This will make the code thread safe, but it will be incredibly slow, and you might as well not use multiple threads.
3. ...

There is no rule that makes the code thread safe, the only thing you can do is make sure that your code will work no matter how many times is it being actively executed, each thread can be interrupted at any point, with each thread being in its own state/location, and this for each function (static or otherwise) that is accessing common objects.

This worked for me:

nltk.set_proxy('http://user:[email protected]:8080')
nltk.download()

I done it, below code is working for me....

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.hello_world, container, false);

        Button newPage = (Button)v.findViewById(R.id.click);
        newPage.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                Intent intent = new Intent(getActivity(), HomeActivity.class);
                startActivity(intent);
            }
        });
        return v;
    }

and Please make sure that your destination activity should be register in Manifest.xml file,

but in my case all tabs are not shown in HomeActivity, is any solution for that ?

You can use selenium and the webdriver for Firefox.

import selenium.webdriver
import selenium.common

options = selenium.webdriver.firefox.options.Options()
# options.headless = True
with selenium.webdriver.Firefox(options=options) as driver:
    driver.get('http://google.com')
    time.sleep(2)
    root=driver.find_element_by_tag_name('html')
    root.screenshot('whole page screenshot.png')

I have found a way to get the desired output. Though it may be somewhat unorthodox way. Anyways here it goes. In the redir.env file I have following code:

#####redir.env#####    
export LOG_FILE=log.txt

      exec 2>>${LOG_FILE}

    function log {
     echo "$1">>${LOG_FILE}
    }

    function message {
     echo "$1"
     echo "$1">>${LOG_FILE}
    }

Then in the actual script I have the following codes:

#!/bin/sh 
. redir.env
echo "Echoed to console only"
log "Written to log file only"
message "To console and log"
echo "This is stderr. Written to log file only" 1>&2

Here echo outputs only to console, log outputs to only log file and message outputs to both the log file and console.

After executing the above script file I have following outputs:

In console

In console
Echoed to console only
To console and log

For the Log file

In Log File Written to log file only
This is stderr. Written to log file only
To console and log

Hope this help.

I was using this line of code:

if (variable.push) {
   // variable is array, since AMAIK only arrays have push() method.
}

A struct (without a typedef) often needs to (or should) be with the keyword struct when used.

struct A;                      // forward declaration
void function( struct A *a );  // using the 'incomplete' type only as pointer

If you typedef your struct you can leave out the struct keyword.

typedef struct A A;          // forward declaration *and* typedef
void function( A *a );

Note that it is legal to reuse the struct name

Try changing the forward declaration to this in your code:

typedef struct context context;

It might be more readable to do add a suffix to indicate struct name and type name:

typedef struct context_s context_t;

table align="center" ... this aligns the table center of page.

Using td align="center" centers the content inside that td, useful for centered aligned text but you will have issues with some email clients centering content in sub level tables so using using td align as a top level method of centering your "container" table on the page is not the way to do it. Use table align instead.

Still use your 100% wrapper table too, purely as a wrapper for the body, as some email clients don't display body background colors but it will show it with the 100% table, so add your body color to both body and the 100% table.

I could go on and on for ages about all the quirks of html email dev. All I can say is test test and test again. Litmus.com is a great tool for testing emails.

The more you do the more you will learn about what works in what email clients.

Hope this helps.

Give an ID to your span and then change the text of target span.

$("#StatusTitle").text("Info");
$("#StatusTitleIcon").removeClass("fa-exclamation").addClass("fa-info-circle"); 

<i id="StatusTitleIcon" class="fa fa-exclamation fa-fw"></i>
<span id="StatusTitle">Error</span>

Here "Error" text will become "Info" and their fontawesome icons will be changed as well.

1. First declare the marker:

this.marker = new google.maps.Marker({
   position: new google.maps.LatLng(12.924640523603115,77.61965398949724),
   map: map
});

2. Call the method to plot the marker on click:

this.placeMarker(coordinates, this.map);

3. Define the function:

placeMarker(location, map) {
    var marker = new google.maps.Marker({
        position: location,
        map: map
    });
    this.markersArray.push(marker);
}

Instead of including locale and all that fancy stuff, if you know for FACT your string is convertible just do this:

#include <iostream>
#include <string>

using namespace std;

int main()
{
  wstring w(L"bla");
  string result;
  for(char x : w)
    result += x;

  cout << result << '\n';
}

Live example here

I think the XML format can be so diverse that it's impossible to write a code that could do this without a very strict defined XML format. Here is what I mean:

<persons>
    <person>
        <name>Koen Bok</name>
        <age>26</age>
    </person>
    <person>
        <name>Plutor Heidepeen</name>
        <age>33</age>
    </person>
</persons>

Would become

{'persons': [
    {'name': 'Koen Bok', 'age': 26},
    {'name': 'Plutor Heidepeen', 'age': 33}]
}

But what would this be:

<persons>
    <person name="Koen Bok">
        <locations name="defaults">
            <location long=123 lat=384 />
        </locations>
    </person>
</persons>

See what I mean?
