Just in case anyone will search for it - I used it on several sites, always the customization and RD possibilities were a perfect fit for what I needed. Simple and it is free to use:

Clickable CSS Maps

One note for more scripts on a site: I had some annoying problems with getting to work a map (that worked as a graphic menu) in Drupal 7. There where many other script used, and after handling them, I got stuck with the map - it still didn't work, although the jquery.cssmap.js, CSS (both local) and the script in the where in the right place. Firebug showed me an error and I suddenly eureka - a simple oversight, I left the script code as it was in the example and there was a conflict. Just change the front function "$" to "jQuery" (or other handler) and it works perfect. :]

Here's what I ment (of course you can put it before instead of the ):

<script type="text/javascript">_x000D_
      jQuery(function($){_x000D_
        $('#map-country').cssMap({'size' : 810});_x000D_
       });_x000D_
    </script>

Working for me (remember to change 3 things in code):

• previousWidth (original size of image)

• map_ID (id of your image map)

• img_ID (id of your image)

HTML:

<div style="width:100%;">
    <img id="img_ID" src="http://www.gravatar.com/avatar/0865e7bad648eab23c7d4a843144de48?s=128&d=identicon&r=PG" usemap="#map" border="0" width="100%" alt="" />
</div>
<map id="map_ID" name="map">
<area shape="poly" coords="48,10,80,10,65,42" href="javascript:;" alt="Bandcamp" title="Bandcamp" />
<area shape="poly" coords="30,50,62,50,46,82" href="javascript:;" alt="Facebook" title="Facebook" />
<area shape="poly" coords="66,50,98,50,82,82" href="javascript:;" alt="Soundcloud" title="Soundcloud" />
</map>

Javascript:

window.onload = function () {
    var ImageMap = function (map, img) {
            var n,
                areas = map.getElementsByTagName('area'),
                len = areas.length,
                coords = [],
                previousWidth = 128;
            for (n = 0; n < len; n++) {
                coords[n] = areas[n].coords.split(',');
            }
            this.resize = function () {
                var n, m, clen,
                    x = img.offsetWidth / previousWidth;
                for (n = 0; n < len; n++) {
                    clen = coords[n].length;
                    for (m = 0; m < clen; m++) {
                        coords[n][m] *= x;
                    }
                    areas[n].coords = coords[n].join(',');
                }
                previousWidth = img.offsetWidth;
                return true;
            };
            window.onresize = this.resize;
        },
        imageMap = new ImageMap(document.getElementById('map_ID'), document.getElementById('img_ID'));
    imageMap.resize();
    return;
}

You should check out this plugin:

and the demo:

http://davidlynch.org/js/maphilight/docs/demo_usa.html

if anything, you might be able to borrow some code from it to fix yours.

This one is in my opinion the best one for online (offline however dreamweaver is best): http://www.maschek.hu/imagemap/imgmap

{
    if (AllDropDownList[i].Text == "nnnnnnnnnnn")
    {
        AllDropDownList[i].Click();
        _browserInstance.ScreenCapture("nnnnnnnnnnnnnnnnnnnnnn");

For an iPhone 7/7 Plus or newer, use these three Haptic feedback APIs.

Available APIs

For notifications:

let generator = UINotificationFeedbackGenerator()
generator.notificationOccured(style: .error)

Available styles are .error, .success, and .warning. Each has its own distinctive feel.
From the docs:

A concrete UIFeedbackGenerator subclass that creates haptics to communicate successes, failures, and warnings.

For simple vibrations:

let generator = UIImpactFeedbackGenerator(style: .medium)
generator.impactOccured()

Available styles are .heavy, .medium, and .light. These are simple vibrations with varying degrees of "hardness".
From the docs:

A concrete UIFeedbackGenerator subclass that creates haptics to simulate physical impacts

For when the user selected an item

let generator = UISelectionFeedbackGenerator()
generator.selectionChanged()

This is the least noticeable of all the haptics, and so is the most suitable for when haptics should not be taking over the app experience.
From the docs:

A concrete UIFeedbackGenerator subclass that creates haptics to indicate a change in selection.

Notes

There are a couple of things worth remembering when using these APIs.

Note A

You do not actually create the haptic. You request the system generate a haptic. The system will decide based on the below:

• If haptics are possible on the device (whether it has a Taptic Engine in this case)
• Whether the app may record audio (haptics do not generate during recording to prevent unwanted interference)
• Whether haptics are enabled in system Settings.

Therefore, the system will silently ignore your request for a haptic if it is not possible. If this is due to an unsupported device, you could try this:

func haptic() {
    // Get whether the device can generate haptics or not
    // If feedbackSupportLevel is nil, will assign 0
    let feedbackSupportLevel = UIDevice.current.value(forKey: "_feedbackSupportLevel") as? Int ?? 0

    switch feedbackSupportLevel { 
    case 2:
        // 2 means the device has a Taptic Engine
        // Put Taptic Engine code here, using the APIs explained above

    case 1: 
    // 1 means no Taptic Engine, but will support AudioToolbox
    // AudioToolbox code from the myriad of other answers!

    default: // 0
        // No haptic support
        // Do something else, like a beeping noise or LED flash instead of haptics
    }

Substitute the comments in the switch-case statements, and this haptic generation code will be portable to other iOS devices. It will generate the highest level of haptic possible.

Note B

• Due to the fact that generating haptics is a hardware-level task, there may be latency between when you call the haptic-generation code, and when it actually happens. For this reason, the Taptic Engine APIs all have a prepare() method, to put it in a state of readiness. Using your Game Over example: You may know that the game is about to end, by the user having very low HP, or a dangerous monster being near them.
• If you don't generate a haptic within a few seconds, the Taptic Engine will go back into an idle state (to save battery life)

In this case, preparing the Taptic Engine would create a higher-quality, more responsive experience.

For example, let's say your app uses a pan gesture recogniser to change the portion of the world visible. You want a haptic to generate when the user 'looks' round 360 degrees. Here is how you could use prepare():

@IBAction func userChangedViewablePortionOfWorld(_ gesture: UIPanGestureRecogniser!) {

    haptic = UIImpactFeedbackGenerator(style: .heavy)

    switch gesture.state {
        case .began:
            // The user started dragging the screen.
            haptic.prepare()

        case .changed:
            // The user trying to 'look' in another direction
            // Code to change viewable portion of the virtual world

            if virtualWorldViewpointDegreeMiddle = 360.0 { 
                haptic.impactOccured()
            }
        
        default:
            break

} 

Despite the danger of stating the obvious: With a unit test you want to test the correct behaviour of the object - and this is defined in terms of its public interface. You are not interested in how the object accomplishes this task - this is an implementation detail and not visible to the outside. This is one of the things why OO was invented: That implementation details are hidden. So there is no point in testing private members. You said you need 100% coverage. If there is a piece of code that cannot be tested by using the public interface of the object, then this piece of code is actually never called and hence not testable. Remove it.

2,147,483,647 bytes, since the value is a signed integer (Int32). That's probably more than you'll need.

Make sure your code is in DOM Ready as pointed by rocket-hazmat

.click()

$('#RootNode').click(function(){
  //do something
});

document.getElementById("RootNode").onclick = function(){//do something}

Use event Delegation/

$(document).on("click", "#RootNode", function(){
   //do something
});

Wrap Code in Dom Ready

$(document).ready(function(){
    $('#RootNode').click(function(){
     //do something
    });
});

The easiest with Java 8 is:

outbound.stream().skip(n % outbound.size()).findFirst().get()

where n is a random integer. Of course it is of less performance than that with the for(elem: Col)

For those using asyncio, an easy way is to use asyncio.wait_for():

async def my_loop():
    res = False
    while not res:
        res = await do_something()

await asyncio.wait_for(my_loop(), 10)

It depends on how you want to use the data in the excel file. If you want to import it into mysql, you could simply save it as a CSV formatted file and then use fgetcsv to parse it.

It depends on when the self executing anonymous function is running. It is possible that it is running before window.document is defined.

In that case, try adding a listener

window.addEventListener('load', yourFunction, false);
// ..... or 
window.addEventListener('DOMContentLoaded', yourFunction, false);

yourFunction () {
  // some ocde

}

Update: (after the update of the question and inclusion of the code)

Read the following about the issues in referencing DOM elements from a JavaScript inserted and run in head element:
- “getElementsByTagName(…)[0]” is undefined?
- Traversing the DOM

Simply use this

echo date('Y-m-d',strtotime("yesterday"));
echo date('Y-m-d',strtotime("tomorrow"));

Use lodash.sortBy, (instructions using commonjs, you can also just put the script include-tag for the cdn at the top of your html)

var sortBy = require('lodash.sortby');
// or
sortBy = require('lodash').sortBy;

Descending order

var descendingOrder = sortBy( homes, 'price' ).reverse();

Ascending order

var ascendingOrder = sortBy( homes, 'price' );

I have tried all the solutions above, but the following solved my problem

chcon -R -t httpd_sys_rw_content_t your_file_directory

You need to understand the different between pass-by-reference and pass-by-value.

Basically, C only support pass-by-value. So you can't reference a variable directly when pass it to a function. If you want to change the variable out a function, which the swap do, you need to use pass-by-reference. To implement pass-by-reference in C, need to use pointer, which can dereference to the value.

The function:

void intSwap(int* a, int* b)

It pass two pointers value to intSwap, and in the function, you swap the values which a/b pointed to, but not the pointer itself. That's why R. Martinho & Dan Fego said it swap two integers, not pointers.

For chars, I think you mean string, are more complicate. String in C is implement as a chars array, which referenced by a char*, a pointer, as the string value. And if you want to pass a char* by pass-by-reference, you need to use the ponter of char*, so you get char**.

Maybe the code below more clearly:

typedef char* str;
void strSwap(str* a, str* b);

The syntax swap(int& a, int& b) is C++, which mean pass-by-reference directly. Maybe some C compiler implement too.

Hope I make it more clearly, not comfuse.

VB.Net code based implementation of kobusb's Border control solution. I used it to populate a ListBox of Button controls. The Button controls are created from MEF extensions. Each extension uses MEF's ExportMetaData attribute for a Description of the extension. The extensions are VisiFire charting objects. The user pushes a button, selected from the list of buttons, to execute the desired chart.

        ' Create a ListBox of Buttons, one button for each MEF charting component. 
    For Each c As Lazy(Of ICharts, IDictionary(Of String, Object)) In ext.ChartDescriptions
        Dim brdr As New Border
        brdr.BorderBrush = Brushes.Black
        brdr.BorderThickness = New Thickness(2, 2, 2, 2)
        brdr.CornerRadius = New CornerRadius(8, 8, 8, 8)
        Dim btn As New Button
        AddHandler btn.Click, AddressOf GenericButtonClick
        brdr.Child = btn
        brdr.Background = btn.Background
        btn.Margin = brdr.BorderThickness
        btn.Width = ChartsLBx.ActualWidth - 22
        btn.BorderThickness = New Thickness(0, 0, 0, 0)
        btn.Height = 22
        btn.Content = c.Metadata("Description")
        btn.Tag = c
        btn.ToolTip = "Push button to see " & c.Metadata("Description").ToString & " chart"
        Dim lbi As New ListBoxItem
        lbi.Content = brdr

You can use some div or span instead of button and then on click call some function which submits form at he end.

<form id="my_form">
   <span onclick="submit()">submit</span>
</form>

<script>
   function submit()
   {   
       //do something
       $("#my_form").submit();
   }
</script>

InetAddress.isReachable() according to javadoc:

".. A typical implementation will use ICMP ECHO REQUESTs if the privilege can be obtained, otherwise it will try to establish a TCP connection on port 7 (Echo) of the destination host..".

Option #1 (ICMP) usually requires administrative (root) rights.

driver = webdriver.Firefox(...)  # Or Chrome(), or Ie(), or Opera()

username = driver.find_element_by_id("username")
password = driver.find_element_by_id("password")

username.send_keys("YourUsername")
password.send_keys("Pa55worD")

driver.find_element_by_name("submit").click()

Notes to your code:

• find_element_by_name('Username'): Username capitalized doesn't match anything.
• Select() is used to act on a Select Element (https://developer.mozilla.org/en-US/docs/Web/HTML/Element/select)

I'm not sure what jQuery api you're looking at, but you should only have to specify id.

$('#thumb').removeAttr('id');

I use this piece of code, its quite nice :)

    <script language="javascript" src="http://code.jquery.com/jquery-1.4.1.js" type="text/javascript"></script>
<script language="javascript">
$(document).ready(function(){
    $(".div_container").mousemove(function(e){
        var parentOffset = $(this).parent().offset();
        var relativeXPosition = (e.pageX - parentOffset.left); //offset -> method allows you to retrieve the current position of an element 'relative' to the document
        var relativeYPosition = (e.pageY - parentOffset.top);
        $("#header2").html("<p><strong>X-Position: </strong>"+relativeXPosition+" | <strong>Y-Position: </strong>"+relativeYPosition+"</p>")
    }).mouseout(function(){
        $("#header2").html("<p><strong>X-Position: </strong>"+relativeXPosition+" | <strong>Y-Position: </strong>"+relativeYPosition+"</p>")
    });
});
</script>

The solucion that work for me is the following

$filter('filter')(data, {'id':10}) 

I would just not add it in the first place:

 var sb = new StringBuilder();

 bool first = true;
 foreach (var foo in items) {
    if (first)
        first = false;
    else
        sb.Append('&');

    // for example:
    var escapedValue = System.Web.HttpUtility.UrlEncode(foo);

    sb.Append(key).Append('=').Append(escapedValue);
 }

 var s = sb.ToString();

In my opinion every programmer has his or her own "words" that is used every time you need an arbitrary word when programming. For some people it's the first words from a childs song, for other it's names and for other its something completely different. Now for the programmer community there are these "words" as well, and these words are 'foo' and 'bar'. The use of this is that if you have to communicate publicly about programming you don't have to say that you would use arbitratry words, you would simply write 'foo' or 'bar' and every programmer knows that this is just arbitrary words.

This is the way I solved my problem:

1. Right click the folder that has uncommitted changes on your local
2. Click Team > Advanced > Assume Unchanged
3. Pull from master.

UPDATE:

As Hugo Zuleta rightly pointed out, you should be careful while applying this. He says that it might end up saying the branch is up to date, but the changes aren't shown, resulting in desync from the branch.

You would use it as the first line of a subclass constructor to call the constructor of its parent class.

For example:

public class TheSuper{
    public TheSuper(){
        eatCake();
    }
}

public class TheSub extends TheSuper{
    public TheSub(){
        super();
        eatMoreCake();
    }
}

Constructing an instance of TheSub would call both eatCake() and eatMoreCake()

Maybe I'm not understanding the question but here is my simple solution that works -

# I want to Display total heads bent this machine so I define a label -
TotalHeadsLabel3 = Label(leftFrame)
TotalHeadsLabel3.config(font=Helv12,fg='blue',text="Total heads " + str(TotalHeads))
TotalHeadsLabel3.pack(side=TOP)

# I update the int variable adding the quantity bent -
TotalHeads = TotalHeads + headQtyBent # update ready to write to file & display
TotalHeadsLabel3.config(text="Total Heads "+str(TotalHeads)) # update label with new qty

I agree that labels are not automatically updated but can easily be updated with the

<label name>.config(text="<new text>" + str(<variable name>))

That just needs to be included in your code after the variable is updated.

try this code I think it is more optimal.

HeaderRow is used to repeat the header of the table for each new page automatically

        BaseFont bfTimes = BaseFont.CreateFont(BaseFont.TIMES_ROMAN, BaseFont.CP1252, false);
        iTextSharp.text.Font times = new iTextSharp.text.Font(bfTimes, 6, iTextSharp.text.Font.NORMAL, iTextSharp.text.BaseColor.BLACK);

        PdfPTable table = new PdfPTable(10) { HorizontalAlignment = Element.ALIGN_CENTER, WidthPercentage = 100, HeaderRows = 2 };
        table.SetWidths(new float[] { 2f, 6f, 6f, 3f, 5f, 8f, 5f, 5f, 5f, 5f });
        table.AddCell(new PdfPCell(new Phrase("SER.\nNO.", times)) { Rowspan = 2, GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("TYPE OF SHIPPING", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("ORDER NO.", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("QTY.", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("DISCHARGE PPORT", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("DESCRIPTION OF GOODS", times)) { Rowspan = 2, GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("LINE DOC. RECL DATE", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("CLEARANCE DATE", times)) { Rowspan = 2, GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("CUSTOM PERMIT NO.", times)) { Rowspan = 2, GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("DISPATCH DATE", times)) { Rowspan = 2, GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("AWB/BL NO.", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("COMPLEX NAME", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("G. W. Kgs.", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("DESTINATION", times)) { GrayFill = 0.95f });
        table.AddCell(new PdfPCell(new Phrase("OWNER DOC. RECL DATE", times)) { GrayFill = 0.95f });

Try this:

SELECT SUM(transaction_amount) FROM TransactionMaster WHERE Card_No ='123' AND CONVERT(VARCHAR(10),GETDATE(),111)

The GETDATE() function returns the current date and time from the SQL Server.

While inspecting HTML with the Browser Development tool you prefer (eg Chrome Devtools) find the <head> element and delete it at all.

Notice that this will also remove js but for me it is the fastest way to get the page naked.

Most likely, the userdata() function is returning an object, not a string. Look into the documentation (or var_dump the return value) to find out which value you need to use.

select min(table.id), table.column1
from table 
group by table.column1

onchange="if(this.selectedIndex < 1){this.options[this.selectedIndex].selected = !1}">

With CSS: table {float:left;}? ?

I've been trying to deploy a simple Angular 7 application, to an Azure Web App. Everything worked fine, until the point where you refreshed the page. Doing so, was presenting me with an 500 error - moved content. I've read both on the Angular docs and in around a good few forums, that I need to add a web.config file to my deployed solution and make sure the rewrite rule fallback to the index.html file. After hours of frustration and trial and error tests, I've found the error was quite simple: adding a tag around my file markup.

A recursive function is a function that calls itself

If the function keeps calling itself, how does it know when to stop? You set up a condition, known as a base case. Base cases tell our recursive call when to stop, otherwise it will loop infinitely.

What was a good learning example for me, since I have a strong background in math, was factorial. By the comments below, it seems the factorial function may be a bit too much, I'll leave it here just in case you wanted it.

function fact($n) {
  if ($n === 0) { // our base case
     return 1;
  }
  else {
     return $n * fact($n-1); // <--calling itself.
  }
}

In regards to using recursive functions in web development, I do not personally resort to using recursive calls. Not that I would consider it bad practice to rely on recursion, but they shouldn't be your first option. They can be deadly if not used properly.

Although I cannot compete with the directory example, I hope this helps somewhat.

(4/20/10) Update:

It would also be helpful to check out this question, where the accepted answer demonstrates in laymen terms how a recursive function works. Even though the OP's question dealt with Java, the concept is the same,

Accepted answer fails to mention how to delete the .swp file.

Hit "D" when the prompt comes up and it will remove it.

In my case, after I hit D it left the latest saved version intact and deleted the .swp which got created because I exited VIM incorrectly

Requirement : Accessing the static Resources (images/videos., etc.,) from outside of WEBROOT directory or from local disk

Step 1 :
Create a folder under webapps of tomcat server., let us say the folder name is myproj

Step 2 :
Under myproj create a WEB-INF folder under this create a simple web.xml

code under web.xml

<web-app>
</web-app>

Directory Structure for the above two steps

c:\programfile\apachesoftwarefoundation\tomcat\...\webapps
                                                            |
                                                            |---myproj
                                                            |   |
                                                            |   |---WEB-INF
                                                                |   |
                                                                    |---web.xml

Step 3:
Now create a xml file with name myproj.xml under the following location

c:\programfile\apachesoftwarefoundation\tomcat\conf\catalina\localhost

CODE in myproj.xml:

<Context path="/myproj/images" docBase="e:/myproj/" crossContext="false" debug="0" reloadable="true" privileged="true" /> 

Step 4:
4 A) Now create a folder with name myproj in E drive of your hard disk and create a new

folder with name images and place some images in images folder (e:myproj\images\)

Let us suppose myfoto.jpg is placed under e:\myproj\images\myfoto.jpg

4 B) Now create a folder with name WEB-INF in e:\myproj\WEB-INF and create a web.xml in WEB-INF folder

Code in web.xml

<web-app>
</web-app>

Step 5:
Now create a .html document with name index.html and place under e:\myproj

CODE under index.html Welcome to Myproj

The Directory Structure for the above Step 4 and Step 5 is as follows

E:\myproj
    |--index.html
    |
    |--images
    |     |----myfoto.jpg
    |
    |--WEB-INF
    |     |--web.xml

Step 6:
Now start the apache tomcat server

Step 7:
open the browser and type the url as follows

http://localhost:8080/myproj    

then u display the content which is provided in index.html

Step 8:
To Access the Images under your local hard disk (outside of webroot)

http://localhost:8080/myproj/images/myfoto.jpg

There is a version conflict between jar/dependency please check all version of spring is same. if you use maven remove version of dependency and use Spring.io dependency.it handle version conflict. Add this in your pom

 <dependency>
            <groupId>io.spring.platform</groupId>
            <artifactId>platform-bom</artifactId>
            <version>2.0.1.RELEASE</version>
            <type>pom</type>
            <scope>import</scope>

Correct solution with "File" class to get the directory - the "path" of the file:

String path = new File("C:\\Temp\\your directory\\yourfile.txt").getParent();

which will return:

path = "C:\\Temp\\your directory"

Adding this because nobody did yet, and this seems to be asked for and implemented a lot with hashes, but it's always done very poorly...

This takes a string input, and a maximum number you want the hash to equal, and produces a unique number based on the string input.

You can use this to produce a unique index into an array of images (If you want to return a specific avatar for a user, chosen at random, but also chosen based on their name, so it will always be assigned to someone with that name).

You can also use this, of course, to return an index into an array of colors, like for generating unique avatar background colors based on someone's name.

function hashInt (str, max = 1000) {
    var hash = 0;
    for (var i = 0; i < str.length; i++) {
      hash = ((hash << 5) - hash) + str.charCodeAt(i);
      hash = hash & hash;
    }
    return Math.round(max * Math.abs(hash) / 2147483648);
}

I found the problem. This code was placed in a separate file that was added with a php include() function. And this include was happening before the Bootstrap files were loaded. So the Bootstrap JS file was not loaded yet, causing this modal to not do anything.

With the above code sample is nothing wrong and works as intended when placed in the body part of a html page.

<script type="text/javascript">
$('#memberModal').modal('show');
</script>

Well to obtain all different values in a Dataframe you can use distinct. As you can see in the documentation that method returns another DataFrame. After that you can create a UDF in order to transform each record.

For example:

val df = sc.parallelize(Array((1, 2), (3, 4), (1, 6))).toDF("age", "salary")

// I obtain all different values. If you show you must see only {1, 3}
val distinctValuesDF = df.select(df("age")).distinct

// Define your udf. In this case I defined a simple function, but they can get complicated.
val myTransformationUDF = udf(value => value / 10)

// Run that transformation "over" your DataFrame
val afterTransformationDF = distinctValuesDF.select(myTransformationUDF(col("age")))

This is how you can use the self inside the block:

//calling of the block

 NSString *returnedText= checkIfOutsideMethodIsCalled(self);

NSString* (^checkIfOutsideMethodIsCalled)(*)=^NSString*(id obj)
{
             [obj MethodNameYouWantToCall]; // this is how it will call the object 
            return @"Called";


};

The current version of AVG Free antivirus is incompatible with Microsoft Visual Studio 2015.

1. It does not allow Visual Studio to be installed on the computer. It gets stuck at "Creating restore point". Visual Studio installs perfectly when AVG is turned off.

2. Any code compiled in "Release" mode targeting x86 platform/environment (in project properties) does not compile. It compiles successfully when AVG is turned off.

I posted the issues in AVG support forum but no one responded.

Highlight both rows in the table design view and click on the key icon, they will now be a composite primary key.

I'm not sure of your question, but only one column per table may be an IDENTITY column, not both.

I think there are two different things here. The first one is that normal SSH authentication requires the user to put the account's password (where the account password will be authenticated against different methods, depending on the sshd configuration).

You can avoid putting that password using certificates. With certificates you still have to put a password, but this time is the password of your private key (that's independent of the account's password).

To do this you can follow the instructions pointed out by steveth45:

With Public Key Authentication.

If you want to avoid putting the certificate's password every time then you can use ssh-agent, as pointed out by DigitalRoss

The exact way you do this depends on Unix vs Windows, but essentially you need to run ssh-agent in the background when you log in, and then the first time you log in, run ssh-add to give the agent your passphrase. All ssh-family commands will then consult the agent and automatically pick up your passphrase.

Start here: man ssh-agent.

The only problem of ssh-agent is that, on *nix at least, you have to put the certificates password on every new shell. And then the certificate is "loaded" and you can use it to authenticate against an ssh server without putting any kind of password. But this is on that particular shell.

With keychain you can do the same thing as ssh-agent but "system-wide". Once you turn on your computer, you open a shell and put the password of the certificate. And then, every other shell will use that "loaded" certificate and your password will never be asked again until you restart your PC.

Gnome has a similar application, called Gnome Keyring that asks for your certificate's password the first time you use it and then it stores it securely so you won't be asked again.

The latest version of core-js lib provides the polyfills from a different path. so use the following in the polyfills.js. And also change the target value to es5 in the tsconfig.base.json

/** IE9, IE10 and IE11 requires all of the following polyfills. **/
import 'core-js/es/symbol';
import 'core-js/es/object';
import 'core-js/es/function';
import 'core-js/es/parse-int';
import 'core-js/es/parse-float';
import 'core-js/es/number';
import 'core-js/es/math';

The RemoveInvalidXmlChars method provided by Irishman does not support surrogate characters. To test it, use the following example:

static void Main()
{
    const string content = "\v\U00010330";

    string newContent = RemoveInvalidXmlChars(content);

    Console.WriteLine(newContent);
}

This returns an empty string but it shouldn't! It should return "\U00010330" because the character U+10330 is a valid XML character.

To support surrogate characters, I suggest using the following method:

public static string RemoveInvalidXmlChars(string text)
{
    if (string.IsNullOrEmpty(text))
        return text;

    int length = text.Length;
    StringBuilder stringBuilder = new StringBuilder(length);

    for (int i = 0; i < length; ++i)
    {
        if (XmlConvert.IsXmlChar(text[i]))
        {
            stringBuilder.Append(text[i]);
        }
        else if (i + 1 < length && XmlConvert.IsXmlSurrogatePair(text[i + 1], text[i]))
        {
            stringBuilder.Append(text[i]);
            stringBuilder.Append(text[i + 1]);
            ++i;
        }
    }

    return stringBuilder.ToString();
}

Also you can use ss utility to dump sockets statistics.

To dump summary:

ss -s

Total: 91 (kernel 0)
TCP:   18 (estab 11, closed 0, orphaned 0, synrecv 0, timewait 0/0), ports 0

Transport Total     IP        IPv6
*         0         -         -        
RAW       0         0         0        
UDP       4         2         2        
TCP       18        16        2        
INET      22        18        4        
FRAG      0         0         0

To display all sockets:

ss -a

To display UDP sockets:

ss -u -a

To display TCP sockets:

ss -t -a

Here you can read ss man: ss

If you use an unchangable variable, then it is better to initialize with by lazy { ... } or val. In this case you can be sure that it will always be initialized when needed and at most 1 time.

If you want a non-null variable, that can change it's value, use lateinit var. In Android development you can later initialize it in such events like onCreate, onResume. Be aware, that if you call REST request and access this variable, it may lead to an exception UninitializedPropertyAccessException: lateinit property yourVariable has not been initialized, because the request can execute faster than that variable could initialize.

This answer might help someone...

All these answers didnt help, then I realised I forgot to check one crucial thing.. The port :)

I have mysql running in a docker container running on a different port. I was pointing to my host machine on port 3306, which I have a mysql server running on. My container exposes the server on port 33060. So all this time, i was looking at the wrong server! doh!

an apache server is an http server which can serve any simple http requests, where tomcat server is actually a servlet container which can serve java servlet requests.

Web server [apache] process web client (web browsers) requests and forwards it to servlet container [tomcat] and container process the requests and sends response which gets forwarded by web server to the web client [browser].

You're missing quotes for $_GET['sel'] - fixing this might help solving your issue sooner :)

A lot has changed in the Spring world since this question was answered. Spring has simplified getting the current user in a controller. For other beans, Spring has adopted the suggestions of the author and simplified the injection of 'SecurityContextHolder'. More details are in the comments.

This is the solution I've ended up going with. Instead of using SecurityContextHolder in my controller, I want to inject something which uses SecurityContextHolder under the hood but abstracts away that singleton-like class from my code. I've found no way to do this other than rolling my own interface, like so:

public interface SecurityContextFacade {

  SecurityContext getContext();

  void setContext(SecurityContext securityContext);

}

Now, my controller (or whatever POJO) would look like this:

public class FooController {

  private final SecurityContextFacade securityContextFacade;

  public FooController(SecurityContextFacade securityContextFacade) {
    this.securityContextFacade = securityContextFacade;
  }

  public void doSomething(){
    SecurityContext context = securityContextFacade.getContext();
    // do something w/ context
  }

}

And, because of the interface being a point of decoupling, unit testing is straightforward. In this example I use Mockito:

public class FooControllerTest {

  private FooController controller;
  private SecurityContextFacade mockSecurityContextFacade;
  private SecurityContext mockSecurityContext;

  @Before
  public void setUp() throws Exception {
    mockSecurityContextFacade = mock(SecurityContextFacade.class);
    mockSecurityContext = mock(SecurityContext.class);
    stub(mockSecurityContextFacade.getContext()).toReturn(mockSecurityContext);
    controller = new FooController(mockSecurityContextFacade);
  }

  @Test
  public void testDoSomething() {
    controller.doSomething();
    verify(mockSecurityContextFacade).getContext();
  }

}

The default implementation of the interface looks like this:

public class SecurityContextHolderFacade implements SecurityContextFacade {

  public SecurityContext getContext() {
    return SecurityContextHolder.getContext();
  }

  public void setContext(SecurityContext securityContext) {
    SecurityContextHolder.setContext(securityContext);
  }

}

And, finally, the production Spring config looks like this:

<bean id="myController" class="com.foo.FooController">
     ...
  <constructor-arg index="1">
    <bean class="com.foo.SecurityContextHolderFacade">
  </constructor-arg>
</bean>

It seems more than a little silly that Spring, a dependency injection container of all things, has not supplied a way to inject something similar. I understand SecurityContextHolder was inherited from acegi, but still. The thing is, they're so close - if only SecurityContextHolder had a getter to get the underlying SecurityContextHolderStrategy instance (which is an interface), you could inject that. In fact, I even opened a Jira issue to that effect.

One last thing - I've just substantially changed the answer I had here before. Check the history if you're curious but, as a coworker pointed out to me, my previous answer would not work in a multi-threaded environment. The underlying SecurityContextHolderStrategy used by SecurityContextHolder is, by default, an instance of ThreadLocalSecurityContextHolderStrategy, which stores SecurityContexts in a ThreadLocal. Therefore, it is not necessarily a good idea to inject the SecurityContext directly into a bean at initialization time - it may need to be retrieved from the ThreadLocal each time, in a multi-threaded environment, so the correct one is retrieved.

just to add to options: <h:outputText value="&amp;nbsp;" escape="false"/> worked

The fields of your object have in turn their fields, some of which do not implement Serializable. In your case the offending class is TransformGroup. How to solve it?

• if the class is yours, make it Serializable
• if the class is 3rd party, but you don't need it in the serialized form, mark the field as transient
• if you need its data and it's third party, consider other means of serialization, like JSON, XML, BSON, MessagePack, etc. where you can get 3rd party objects serialized without modifying their definitions.

Sorting arrays in VBScript has never been easy; that’s because VBScript doesn’t have a sort command of any kind. In turn, that always meant that VBScript scripters were forced to write their own sort routines, be that a bubble sort routine, a heap sort, a quicksort, or some other type of sorting algorithm.

So (using .Net as it is installed on my pc):

Set outputLines = CreateObject("System.Collections.ArrayList")

'add lines
outputLines.Add output
outputLines.Add output

outputLines.Sort()
For Each outputLine in outputLines
    stdout.WriteLine outputLine
Next

nvarchar stores data as Unicode, so, if you're going to store multilingual data (more than one language) in a data column you need the N variant.

HTML5 adds a maxlength attribute to the textarea element, like so:

<!DOCTYPE html>
<html>
    <body>
        <form action="processForm.php" action="post">
            <label for="story">Tell me your story:</label><br>
            <textarea id="story" maxlength="100"></textarea>
            <input type="submit" value="Submit">
        </form>
    </body>
</html>

This is currently supported in Chrome 13, FF 5, and Safari 5. Not surprisingly, this is not supported in IE 9. (Tested on Win 7)

Cell.getCellType() is deprecated in the latest POI API. If you are using POI API version 3.17, use the below code:

if (Cell.getCellTypeEnum() == CellType.BLANK) {
    //do your stuff here
}

If you have a background image then you will want to set this instead:

html{
  height: 100%;
}
body {
  min-height: 100%;
}

This ensures that your body tag is allowed to continue growing when the content is taller than the viewport and that the background image continues to repeat/scroll/whatever when you start scrolling down.

Remember if you have to support IE6 you will need to find a way to wedge in height:100% for body, IE6 treats height like min-height anyway.

Hy there , in my case i am using asp.net development environment, so i was want to upload those data in asynchronus ajax request , in [webMethod] you can not catch the file uploader since it is not static element , so i had to make a turnover for such solution by fixing the path , than convert the wanted image into bytes to save it in DB .

Here is my javascript function , hope it helps you:

function FixPath(Path)
         {
             var HiddenPath = Path.toString();
             alert(HiddenPath.indexOf("FakePath"));

             if (HiddenPath.indexOf("FakePath") > 1)
             {
                 var UnwantedLength = HiddenPath.indexOf("FakePath") + 7;
                 MainStringLength = HiddenPath.length - UnwantedLength;
                 var thisArray =[];
                 var i = 0;
                 var FinalString= "";
                 while (i < MainStringLength)
                 {
                     thisArray[i] = HiddenPath[UnwantedLength + i + 1];
                     i++;
                 }
                 var j = 0;
                 while (j < MainStringLength-1)
                 {
                     if (thisArray[j] != ",")
                     {
                         FinalString += thisArray[j];
                     }
                     j++;
                 }
                 FinalString = "~" + FinalString;
                 alert(FinalString);
                 return FinalString;
             }
             else
             {
                 return HiddenPath;
             }
         }

here only for testing :

 $(document).ready(function () {
             FixPath("hakounaMatata:/7ekmaTa3mahaLaziz/FakePath/EnsaLmadiLiYghiz");
         });
// this will give you : ~/EnsaLmadiLiYghiz

Since it is being passed a duration of 0, I suppose it is in order to remove the code passed to the setTimeout from the flow of execution. So if it's a function that could take a while, it won't prevent the subsequent code from executing.

1. Open Command Prompt/Terminal and type:

   sqlplus / as SYSDBA

2. SQL prompt will turn up. Now type:

   ALTER USER existing_account_name IDENTIFIED BY new_password ACCOUNT UNLOCK;

3. Voila! You've unlocked your account.

If your terminal/command prompt says:

Node Sass could not find a binding 
for your current environment: 
OS X 64-bit with Node 0.10.x

and you have tried the following commands such as:

npm cache clean --force 
rm -rf node modules 
npm install 
npm rebuild node-sass 
npm rebuild node-sass

& still NOTHING works..

Just run this in the terminal manually:

node node_modules/node-sass/scripts/install.js

now run

npm start or yarn start

{
    "presets": [
        "@babel/preset-env",
        "@babel/preset-react"
    ],
    "plugins": [
        [
          "@babel/plugin-proposal-class-properties"
        ]
    ]
}

replace your .babelrc file with above code. it fixed the issue for me.

I am trying to do something similar to this. As commented above, I think you would want to build a new image with a custom Dockerfile (using the image you pulled as a base image), ADD your certificate, then RUN update-ca-certificates. This way you will have a consistent state each time you start a container from this new image.

# Dockerfile
FROM some-base-image:0.1
ADD you_certificate.crt:/container/cert/path
RUN update-ca-certificates

Let's say a docker build against that Dockerfile produced IMAGE_ID. On the next docker run -d [any other options] IMAGE_ID, the container started by that command will have your certificate info. Simple and reproducible.

bool hasErrors =  ViewData.ModelState.Values.Any(x => x.Errors.Count > 1);

or iterate with

    foreach (ModelState state in ViewData.ModelState.Values.Where(x => x.Errors.Count > 0))
    {

    }

I don't know if/where it's published, but you can get the latest release by omitting the minor and build numbers.

Latest 1.8.x:

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8/jquery.min.js"></script>

Latest 1.x:

<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>

However, do keep in mind that these links have a much shorter cache timeout than with the full version number, so your users may be downloading them more than you'd like. See The crucial .0 in Google CDN references to jQuery 1.x.0 for more information.

I'm assuming from your question that you don't want directories names, just files.

Walk function

Credits go to Justin Maier in this gist

If you want just an array of the files paths use return_object: false:

const fs = require('fs').promises;
const path = require('path');

async function walk(dir) {
    let files = await fs.readdir(dir);
    files = await Promise.all(files.map(async file => {
        const filePath = path.join(dir, file);
        const stats = await fs.stat(filePath);
        if (stats.isDirectory()) return walk(filePath);
        else if(stats.isFile()) return filePath;
    }));

    return files.reduce((all, folderContents) => all.concat(folderContents), []);
}

Usage

async function main() {
   console.log(await walk('animals'))
}

Output

[
  "/animals/all.jpg",
  "/animals/mammals/cat.jpg",
  "/animals/mammals/dog.jpg",
  "/animals/insects/bee.jpg"

From here:

Windows

1. Locate the my.ini, which store in the MySQL installation folder.

For Example, C:\Program Files\MySQL\MySQL Server 5.1\my.ini

2. Open the “my.ini” with our favor text editor.

#Path to installation directory. All paths are usually resolved relative to this.
basedir="C:/Program Files/MySQL/MySQL Server 5.1/"
 
#Path to the database root
datadir="C:/Documents and Settings/All Users/Application Data/MySQL/MySQL Server 5.1/Data/"

Find the “datadir”, this is the where does MySQL stored the data in Windows.

Linux

1. Locate the my.cnf with the find / -name my.cnf command.

yongmo@myserver:~$ find / -name my.cnf
find: /home/lost+found: Permission denied
find: /lost+found: Permission denied
/etc/mysql/my.cnf

2. View the my.cnf file like this: cat /etc/mysql/my.cnf

yongmo@myserver:~$ cat /etc/mysql/my.cnf
#
# The MySQL database server configuration file.
#
# You can copy this to one of:
# - "/etc/mysql/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.
# 
[mysqld]
#
# * Basic Settings
#
user   = mysql
pid-file = /var/run/mysqld/mysqld.pid
socket  = /var/run/mysqld/mysqld.sock
port   = 3306
basedir  = /usr
datadir  = /var/lib/mysql
tmpdir  = /tmp
language = /usr/share/mysql/english
skip-external-locking

3. Find the “datadir”, this is where does MySQL stored the data in Linux system.

If you got only one column in the range to clean, just add "(1)" to the end. It indicates in wich column of the range Excel will remove the duplicates. Something like:

 Sub norepeat()

    Range("C8:C16").RemoveDuplicates (1)

End Sub

Simply just go to Values - styles and inside styles and type your color

My problem was that I was looking at it from the long angle:

function new_line() {
    var html= '<div><br><input type="text" value="" id="dateP_'+ i +'"></div>';
    document.getElementById("container").innerHTML += html;

    $('#dateP_'+i).datepicker({
        showOn: 'button',
        buttonImage: 'calendar.gif',
        buttonImageOnly: true
    });
    i++;
}

The guys have given the simple solution, which will do be you should have a look at the help - it's good, looks like a lot in one go but it's actually quick to read:

I had trouble with a .pfx file with openconnect. Renaming didn't solve the problem. I used keytool to convert it to .p12 and it worked.

keytool -importkeystore -destkeystore new.p12 -deststoretype pkcs12 -srckeystore original.pfx

In my case the password for the new file (new.p12) had to be the same as the password for the .pfx file.

Since PyYAML's yaml.load() function parses YAML documents to native Python data structures, you can just access items by key or index. Using the example from the question you linked:

import yaml
with open('tree.yaml', 'r') as f:
    doc = yaml.load(f)

To access branch1 text you would use:

txt = doc["treeroot"]["branch1"]
print txt
"branch1 text"

because, in your YAML document, the value of the branch1 key is under the treeroot key.

Use the % instead of the / when you divide. This will return the remainder for you. So in your case

26 % 7 = 5

This worked for me:

Check field type in table just save time stamp value in datatype like bigint etc.

Not datetime type

You can still use the textmode and force the linefeed-newline with the keyword argument newline

f = open("./foo",'w',newline='\n')

Tested with Python 3.4.2.

Edit: This does not work in Python 2.7.

There is no event raised when a class changes. The alternative is to manually raise an event when you programatically change the class:

$someElement.on('event', function() {
    $('#myDiv').addClass('submission-ok').trigger('classChange');
});

// in another js file, far, far away
$('#myDiv').on('classChange', function() {
     // do stuff
});

UPDATE

This question seems to be gathering some visitors, so here is an update with an approach which can be used without having to modify existing code using the new MutationObserver:

var $div = $("#foo");_x000D_
var observer = new MutationObserver(function(mutations) {_x000D_
  mutations.forEach(function(mutation) {_x000D_
    if (mutation.attributeName === "class") {_x000D_
      var attributeValue = $(mutation.target).prop(mutation.attributeName);_x000D_
      console.log("Class attribute changed to:", attributeValue);_x000D_
    }_x000D_
  });_x000D_
});_x000D_
observer.observe($div[0], {_x000D_
  attributes: true_x000D_
});_x000D_
_x000D_
$div.addClass('red');

.red { color: #C00; }

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="foo" class="bar">#foo.bar</div>

Be aware that the MutationObserver is only available for newer browsers, specifically Chrome 26, FF 14, IE 11, Opera 15 and Safari 6. See MDN for more details. If you need to support legacy browsers then you will need to use the method I outlined in my first example.

This is easy method worked for me.

boston = load_boston()
boston_frame = pd.DataFrame(data=boston.data, columns=boston.feature_names)
boston_frame["target"] = boston.target

But this can applied to load_iris as well.

you could perhaps use:

application/x-binary

what is MIME types

list of mime types

You need to somehow create a table with these values and then use NOT IN. This can be done with a temporary table, a CTE (Common Table Expression) or a Table Values Constructor (available in SQL-Server 2008):

SELECT email
FROM
    ( VALUES 
        ('email1')
      , ('email2')
      , ('email3')
    ) AS Checking (email)
WHERE email NOT IN 
      ( SELECT email 
        FROM Users
      ) 

The second result can be found with a LEFT JOIN or an EXISTS subquery:

SELECT email
     , CASE WHEN EXISTS ( SELECT * 
                          FROM Users u
                          WHERE u.email = Checking.email
                        ) 
            THEN 'Exists'
            ELSE 'Not exists'
       END AS status 
FROM
    ( VALUES 
        ('email1')
      , ('email2')
      , ('email3')
    ) AS Checking (email)

Pages are intended for use in Navigation applications (usually with Back and Forward buttons, e.g. Internet Explorer). Pages must be hosted in a NavigationWindow or a Frame

Windows are just normal WPF application Windows, but can host Pages via a Frame container

Here's my implementation of the $parser solution that @Mark Rajcok recommends as the best method. It's essentially @pkozlowski.opensource's excellent $parser for text answer but rewritten to only allow numerics. All credit goes to him, this is just to save you the 5 minutes of reading that answer and then rewriting your own:

app.directive('numericOnly', function(){
    return {
        require: 'ngModel',
        link: function(scope, element, attrs, modelCtrl) {

            modelCtrl.$parsers.push(function (inputValue) {
                var transformedInput = inputValue ? inputValue.replace(/[^\d.-]/g,'') : null;

                if (transformedInput!=inputValue) {
                    modelCtrl.$setViewValue(transformedInput);
                    modelCtrl.$render();
                }

                return transformedInput;
            });
        }
    };
});

And you'd use it like this:

<input type="text" name="number" ng-model="num_things" numeric-only>

Interestingly, spaces never reach the parser unless surrounded by an alphanumeric, so you'd have to .trim() as needed. Also, this parser does NOT work on <input type="number">. For some reason, non-numerics never make it to the parser where they'd be removed, but they do make it into the input control itself.

I know this is an old post but, I've always used an updater extension method:

      public static void Update<TSource>(this IEnumerable<TSource> outer, Action<TSource> updator)
        {
            foreach (var item in outer)
            {
                updator(item);
            }
        }

list.Where(w => w.Name == "height").ToList().Update(u => u.height = 30);

I know this doesn't really answer your question, but different View Engines have different purposes. The Spark View Engine, for example, aims to rid your views of "tag soup" by trying to make everything fluent and readable.

Your best bet would be to just look at some implementations. If it looks appealing to the intent of your solution, try it out. You can mix and match view engines in MVC, so it shouldn't be an issue if you decide to not go with a specific engine.

JSON.stringify(data).length return string length not Object length, you can use Object.keys.

<% for(var i=0; i < Object.keys(data).length ; i++) {%>

https://stackoverflow.com/a/14379528/3224296

Works fine for me with one change - fourth line should be:

cell.Value = Trim(cell.Value)

Edit: If it appears to be stuck in a loop, I'd add

Debug.Print cell.Address

inside your For ... Next loop to get a bit more info on what's happening.

I also suspect that Trim only strips spaces - are you sure you haven't got some other kind of non-display character in there?

Open a new connection when the Node.js application starts, and reuse the existing db connection object:

/server.js

import express from 'express';
import Promise from 'bluebird';
import logger from 'winston';
import { MongoClient } from 'mongodb';
import config from './config';
import usersRestApi from './api/users';

const app = express();

app.use('/api/users', usersRestApi);

app.get('/', (req, res) => {
  res.send('Hello World');
});

// Create a MongoDB connection pool and start the application
// after the database connection is ready
MongoClient.connect(config.database.url, { promiseLibrary: Promise }, (err, db) => {
  if (err) {
    logger.warn(`Failed to connect to the database. ${err.stack}`);
  }
  app.locals.db = db;
  app.listen(config.port, () => {
    logger.info(`Node.js app is listening at http://localhost:${config.port}`);
  });
});

/api/users.js

import { Router } from 'express';
import { ObjectID } from 'mongodb';

const router = new Router();

router.get('/:id', async (req, res, next) => {
  try {
    const db = req.app.locals.db;
    const id = new ObjectID(req.params.id);
    const user = await db.collection('user').findOne({ _id: id }, {
      email: 1,
      firstName: 1,
      lastName: 1
    });

    if (user) {
      user.id = req.params.id;
      res.send(user);
    } else {
      res.sendStatus(404);
    }
  } catch (err) {
    next(err);
  }
});

export default router;

Just do:

$object = new stdClass();
$object->name = "My name";
$myArray[] = $object;

You need to create the object first (the new line) and then push it onto the end of the array (the [] line).

You can also do this:

$myArray[] = (object) ['name' => 'My name'];

However I would argue that's not as readable, even if it is more succinct.

Or, if you know the width of the two "side" images and don't want to deal with floats:

<div class="container">
    <div class="left-panel"><img src="myleftimage" /></div>
    <div class="center-panel">Content goes here...</div>
    <div class="right-panel"><img src="myrightimage" /></div>
</div>

CSS:

.container {
    position:relative;
    padding-left:50px;
    padding-right:50px;
}

.container .left-panel {
    width: 50px;
    position:absolute;
    left:0px;
    top:0px;
}

.container .right-panel {
    width: 50px;
    position:absolute;
    right:0px;
    top:0px;
}

.container .center-panel {
    background: url('mymiddleimage');
}

Notes:

Position:relative on the parent div is used to make absolutely positioned children position themselves relative to that node.

All these answers and there is STILL just one missing. When you create your auth credential in the Google API section of the dev console, make sure (especially if it is your first one) that you have clicked on the 'consent screen' option. If you don't have the 'title' and any other required field filled out the call will fail with this option.

I agree that in 95% of cases, all you need is sudo yum update openssl

However, if you need a specific version of openssl or specific functionality, which is not in CentOS repository, you probably need to compile from source. The other answers here were incomplete. Below is what worked (CentOS 6.9), although this may introduce incompatibilities with installed software, and will not auto-update the openssl.

Choose openssl version from https://www.openssl.org/source/

• At the time of this writing July 1, 2017, the needed version was dated 2017-May-25 13:09:51, openssl-1.1.0f.tar.gz
• Copy the desired link, and use below, in our case ( https://www.openssl.org/source/openssl-1.1.0f.tar.gz )

Log-in as root:

cd /usr/local/src/

# OPTIONALLY CHANGE openssl-1.1.0f.tar.gz to the version which you want
wget https://www.openssl.org/source/openssl-1.1.0f.tar.gz

sha256sum openssl-1.1.0f.tar.gz  #confirm this matches the published hash

tar -zxf openssl-1.1.0f.tar.gz

cd /usr/local/src/openssl-1.1.0f

./config --prefix=/usr/local --openssldir=/usr/local/openssl
make
make test
make install

export LD_LIBRARY_PATH=/usr/local/lib64

#make export permanent
echo "export LD_LIBRARY_PATH=/usr/local/lib64" > /etc/profile.d/ld_library_path.sh
chmod ugo+x /etc/profile.d/ld_library_path.sh

openssl version  #confirm it works

#recommended reboot here

openssl version  #confirm it works after reboot

UNION ALL also works on more data types as well. For example when trying to union spatial data types. For example:

select a.SHAPE from tableA a
union
select b.SHAPE from tableB b

will throw

The data type geometry cannot be used as an operand to the UNION, INTERSECT or EXCEPT operators because it is not comparable.

However union all will not.

You can not do that directly. You need to use std::remove algorithm to move the element to be erased to the end of the vector and then use erase function. Something like: myVector.erase(std::remove(myVector.begin(), myVector.end(), 8), myVec.end());. See this erasing elements from vector for more details.

The API's will provide full access to LIVE data, and developers can thus provide applications and develop against the API without paying licencing fees. Consumers will pay for any data received from the apps provided by third party developers, and so BB will grow their audience and revenue in that way.

The way I resolved it is by using Fragments. These are backwards compatible until API 4 by using the support library.

You make a "wrapper" layout with a FrameLayout in it.

Example:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="match_parent"
     android:layout_height="match_parent"
     android:orientation="vertical" >

     <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:id="@+id/fragment_container"
          android:layout_width="match_parent"
          android:layout_height="match_parent" />
</LinearLayout>

Then you make a FragmentActivity in wich you can replace the FrameLayout any time you want.

Example:

public class SampleFragmentActivity extends FragmentActivity
{

     @Override
 public void onCreate(Bundle savedInstanceState)
 {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.wrapper);

    // Check that the activity is using the layout version with
    // the fragment_container FrameLayout
    if (findViewById(R.id.fragment_container) != null)
    {

        // However, if we're being restored from a previous state,
        // then we don't need to do anything and should return or else
        // we could end up with overlapping fragments.
        if (savedInstanceState != null)
        {
            return;
        }
        updateLayout();
     }
  }

  private void updateLayout()
  {
     Fragment fragment = new SampleFragment();
     fragment.setArguments(getIntent().getExtras());

     // replace original fragment by new fragment
     getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container, fragment).commit();
  }

In the Fragment you inflate/replace you can use the onStart and onCreateView like you normaly would use the onCreate of an activity.

Example:

public class SampleFragment extends Fragment
{

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
    {
        return inflater.inflate(R.layout.yourActualLayout, container, false);
    }

    @Override
    public void onStart()
    {
        // do something with the components, or not!
        TextView text = (TextView) getActivity().findViewById(R.id.text1);

        super.onStart();
    }
}

It sounds like you're doing property checking on an object! If you want to check a property exists (but can be values such as null or 0 in addition to truthy values), the in operator can make for some nice syntax.

var foo = { bar: 1234, baz: null };
console.log("bar in foo:", "bar" in foo); // true
console.log("baz in foo:", "baz" in foo); // true
console.log("otherProp in foo:", "otherProp" in foo) // false
console.log("__proto__ in foo:", "__proto__" in foo) // true

As you can see, the __proto__ property is going to be thrown here. This is true for all inherited properties. For further reading, I'd recommend the MDN page:

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/in

I suggest:

writeLines(c("Hello","World"), "output.txt")

It is shorter and more direct than the current accepted answer. It is not necessary to do:

fileConn<-file("output.txt")
# writeLines command using fileConn connection
close(fileConn)

Because the documentation for writeLines() says:

If the con is a character string, the function calls file to obtain a file connection which is opened for the duration of the function call.

# default settings for writeLines(): sep = "\n", useBytes = FALSE
# so: sep = "" would join all together e.g.

I had this same issue. It turned out that I was loading the jQuery JavaScript file more than once on the page. This was due to included pages (or JSPs, in my case). Once I removed the duplicate reference to the jQuery js file, this error went away.

Maybe you could find that out by looking at the query log.

Can a relational database input latitudes and longitudes of places and roads, and compute the shortest path between them - no. This is one problem that shows SQL is not Turing complete.

But C++ can do it, and can do any problem. Thus it is.

You can always install Cygwin to run a Unix shell under Windows. I used Cygwin extensively with Window XP.

I have used below code in my custom library
call that from my controller like below,

$config['encrypt_name'] = TRUE;<br />
$config['overwrite'] = FALSE;<br />

// upload multiplefiles<br />
$fileUploadResponse = $this->commonmethods->do_upload_multiple_files('profile_picture', $config);

public function do_upload_multiple_files($fieldName, $options) {

    $response = array();
    $files = $_FILES;
    $cpt = count($_FILES[$fieldName]['name']);
    for($i=0; $i<$cpt; $i++)
    {           
        $_FILES[$fieldName]['name']= $files[$fieldName]['name'][$i];
        $_FILES[$fieldName]['type']= $files[$fieldName]['type'][$i];
        $_FILES[$fieldName]['tmp_name']= $files[$fieldName]['tmp_name'][$i];
        $_FILES[$fieldName]['error']= $files[$fieldName]['error'][$i];
        $_FILES[$fieldName]['size']= $files[$fieldName]['size'][$i];    

        $this->CI->load->library('upload');
        $this->CI->upload->initialize($options);

        //upload the image
        if (!$this->CI->upload->do_upload($fieldName)) {
            $response['erros'][] = $this->CI->upload->display_errors();
        } else {
            $response['result'][] = $this->CI->upload->data();
        }
    }

    return $response;
}

This worked for me.

I use the old PHP way..It unsets all session variables and doesn't require to specify each one of them in an array. And after unsetting the variables we destroy the session.

session_unset();
session_destroy();

Since it's a POD struct, you could always memset it to 0 - this might be the easiest way to get the fields initialized (assuming that is appropriate).

You can't access non-static members from a static method. (Note that Main() is static, which is a requirement of .Net). Just make siprimo and volteado static, by placing the static keyword in front of them. e.g.:

 static private long volteado(long a)

Easy approach:

CREATE TABLE T
(
    C [nvarchar](100) NOT NULL UNIQUE,
);

SET XACT_ABORT ON -- Turns on rollback if T-SQL statement raises a run-time error.
SELECT * FROM T; -- Check before.
BEGIN TRAN
    INSERT INTO T VALUES ('A');
    INSERT INTO T VALUES ('B');
    INSERT INTO T VALUES ('B');
    INSERT INTO T VALUES ('C');
COMMIT TRAN
SELECT * FROM T; -- Check after.
DELETE T;

Use the traceback module:

import sys
import traceback

try:
    assert True
    assert 7 == 7
    assert 1 == 2
    # many more statements like this
except AssertionError:
    _, _, tb = sys.exc_info()
    traceback.print_tb(tb) # Fixed format
    tb_info = traceback.extract_tb(tb)
    filename, line, func, text = tb_info[-1]

    print('An error occurred on line {} in statement {}'.format(line, text))
    exit(1)

For some reason it's preferable to find the MenuItem using the ID's.

drawer.getMenu().findItem(R.id.action_something).setChecked(true);

There are two different ways to implement inserting data from one table to another table.

For Existing Table - INSERT INTO SELECT

This method is used when the table is already created in the database earlier and the data is to be inserted into this table from another table. If columns listed in insert clause and select clause are same, they are not required to list them. It is good practice to always list them for readability and scalability purpose.

----Create testable
CREATE TABLE TestTable (FirstName VARCHAR(100), LastName VARCHAR(100))
----INSERT INTO TestTable using SELECT
INSERT INTO TestTable (FirstName, LastName)
SELECT FirstName, LastName
FROM Person.Contact
WHERE EmailPromotion = 2
----Verify that Data in TestTable
SELECT FirstName, LastName
FROM TestTable
----Clean Up Database
DROP TABLE TestTable

For Non-Existing Table - SELECT INTO

This method is used when the table is not created earlier and needs to be created when data from one table is to be inserted into the newly created table from another table. The new table is created with the same data types as selected columns.

----Create a new table and insert into table using SELECT INSERT
SELECT FirstName, LastName
INTO TestTable
FROM Person.Contact
WHERE EmailPromotion = 2
----Verify that Data in TestTable
SELECT FirstName, LastName
FROM TestTable
----Clean Up Database
DROP TABLE TestTable

Ref 1 2

From MySQL 5.7 onwards, this is possible, but requires first enabling the mdl instrument in the performance_schema.setup_instruments table. You can do this temporarily (until the server is next restarted) by running:

UPDATE performance_schema.setup_instruments
SET enabled = 'YES'
WHERE name = 'wait/lock/metadata/sql/mdl';

Or permanently, by adding the following incantation to the [mysqld] section of your my.cnf file (or whatever config files MySQL reads from on your installation):

[mysqld]
performance_schema_instrument = 'wait/lock/metadata/sql/mdl=ON'

(Naturally, MySQL will need to be restarted to make the config change take effect if you take the latter approach.)

Locks you take out after the mdl instrument has been enabled can be seen by running a SELECT against the performance_schema.metadata_locks table. As noted in the docs, GET_LOCK locks have an OBJECT_TYPE of 'USER LEVEL LOCK', so we can filter our query down to them with a WHERE clause:

mysql> SELECT GET_LOCK('foobarbaz', -1);
+---------------------------+
| GET_LOCK('foobarbaz', -1) |
+---------------------------+
|                         1 |
+---------------------------+
1 row in set (0.00 sec)

mysql> SELECT * FROM performance_schema.metadata_locks 
    -> WHERE OBJECT_TYPE='USER LEVEL LOCK'
    -> \G
*************************** 1. row ***************************
          OBJECT_TYPE: USER LEVEL LOCK
        OBJECT_SCHEMA: NULL
          OBJECT_NAME: foobarbaz
OBJECT_INSTANCE_BEGIN: 139872119610944
            LOCK_TYPE: EXCLUSIVE
        LOCK_DURATION: EXPLICIT
          LOCK_STATUS: GRANTED
               SOURCE: item_func.cc:5482
      OWNER_THREAD_ID: 35
       OWNER_EVENT_ID: 3
1 row in set (0.00 sec)

mysql> 

The meanings of the columns in this result are mostly adequately documented at https://dev.mysql.com/doc/refman/en/metadata-locks-table.html, but one point of confusion is worth noting: the OWNER_THREAD_ID column does not contain the connection ID (like would be shown in the PROCESSLIST or returned by CONNECTION_ID()) of the thread that holds the lock. Confusingly, the term "thread ID" is sometimes used as a synonym of "connection ID" in the MySQL documentation, but this is not one of those times. If you want to determine the connection ID of the connection that holds a lock (for instance, in order to kill that connection with KILL), you'll need to look up the PROCESSLIST_ID that corresponds to the THREAD_ID in the performance_schema.threads table. For instance, to kill the connection that was holding my lock above...

mysql> SELECT OWNER_THREAD_ID FROM performance_schema.metadata_locks
    -> WHERE OBJECT_TYPE='USER LEVEL LOCK'
    -> AND OBJECT_NAME='foobarbaz';
+-----------------+
| OWNER_THREAD_ID |
+-----------------+
|              35 |
+-----------------+
1 row in set (0.00 sec)

mysql> SELECT PROCESSLIST_ID FROM performance_schema.threads
    -> WHERE THREAD_ID=35;
+----------------+
| PROCESSLIST_ID |
+----------------+
|             10 |
+----------------+
1 row in set (0.00 sec)

mysql> KILL 10;
Query OK, 0 rows affected (0.00 sec)

Ignore the files ending with .iws, and the workspace.xml and tasks.xml files in your .gitignore Reference

Things seems a little confused in the code in your question, so I am going to give you an example of what I think you are try to do.

First considerations are about mixing HTML, Javascript and CSS:

Why is using onClick() in HTML a bad practice?

Unobtrusive Javascript

Inline Styles vs Classes

I will be removing inline content and splitting these into their appropriate files.

Next, I am going to go with the "click" event and displose of the "change" event, as it is not clear that you want or need both.

Your function changeBackground sets both the backround color and the text color to the same value (your text will not be seen), so I am caching the color value as we don't need to look it up in the DOM twice.

CSS

#TheForm {
    margin-left: 396px;
}
#submitColor {
    margin-left: 48px;
    margin-top: 5px;
}

HTML

<form id="TheForm">
    <input id="color" type="text" />
    <br/>
    <input id="submitColor" value="Submit" type="button" />
</form>
<span id="coltext">This text should have the same color as you put in the text box</span>

Javascript

function changeBackground() {
    var color = document.getElementById("color").value; // cached

    // The working function for changing background color.
    document.bgColor = color;

    // The code I'd like to use for changing the text simultaneously - however it does not work.
    document.getElementById("coltext").style.color = color;
}

document.getElementById("submitColor").addEventListener("click", changeBackground, false);

Color Values

CSS colors are defined using a hexadecimal (hex) notation for the combination of Red, Green, and Blue color values (RGB). The lowest value that can be given to one of the light sources is 0 (hex 00). The highest value is 255 (hex FF).

Hex values are written as 3 double digit numbers, starting with a # sign.

Update: as pointed out by @Ian

Hex can be either 3 or 6 characters long

Source: W3C

Numerical color values

The format of an RGB value in hexadecimal notation is a ‘#’ immediately followed by either three or six hexadecimal characters. The three-digit RGB notation (#rgb) is converted into six-digit form (#rrggbb) by replicating digits, not by adding zeros. For example, #fb0 expands to #ffbb00. This ensures that white (#ffffff) can be specified with the short notation (#fff) and removes any dependencies on the color depth of the display.

Here is an alternative function that will check that your input is a valid CSS Hex Color, it will set the text color only or throw an alert if it is not valid.

For regex testing, I will use this pattern

/^#(?:[0-9a-f]{3}){1,2}$/i

but if you were regex matching and wanted to break the numbers into groups then you would require a different pattern

function changeBackground() {
    var color = document.getElementById("color").value.trim(),
        rxValidHex = /^#(?:[0-9a-f]{3}){1,2}$/i;

    if (rxValidHex.test(color)) {
        document.getElementById("coltext").style.color = color;
    } else {
        alert("Invalid CSS Hex Color");
    }
}

document.getElementById("submitColor").addEventListener("click", changeBackground, false);

On jsfiddle

Here is a further modification that will allow colours by name along with by hex.

function changeBackground() {
    var names = ["AliceBlue", "AntiqueWhite", "Aqua", "Aquamarine", "Azure", "Beige", "Bisque", "Black", "BlanchedAlmond", "Blue", "BlueViolet", "Brown", "BurlyWood", "CadetBlue", "Chartreuse", "Chocolate", "Coral", "CornflowerBlue", "Cornsilk", "Crimson", "Cyan", "DarkBlue", "DarkCyan", "DarkGoldenRod", "DarkGray", "DarkGrey", "DarkGreen", "DarkKhaki", "DarkMagenta", "DarkOliveGreen", "Darkorange", "DarkOrchid", "DarkRed", "DarkSalmon", "DarkSeaGreen", "DarkSlateBlue", "DarkSlateGray", "DarkSlateGrey", "DarkTurquoise", "DarkViolet", "DeepPink", "DeepSkyBlue", "DimGray", "DimGrey", "DodgerBlue", "FireBrick", "FloralWhite", "ForestGreen", "Fuchsia", "Gainsboro", "GhostWhite", "Gold", "GoldenRod", "Gray", "Grey", "Green", "GreenYellow", "HoneyDew", "HotPink", "IndianRed", "Indigo", "Ivory", "Khaki", "Lavender", "LavenderBlush", "LawnGreen", "LemonChiffon", "LightBlue", "LightCoral", "LightCyan", "LightGoldenRodYellow", "LightGray", "LightGrey", "LightGreen", "LightPink", "LightSalmon", "LightSeaGreen", "LightSkyBlue", "LightSlateGray", "LightSlateGrey", "LightSteelBlue", "LightYellow", "Lime", "LimeGreen", "Linen", "Magenta", "Maroon", "MediumAquaMarine", "MediumBlue", "MediumOrchid", "MediumPurple", "MediumSeaGreen", "MediumSlateBlue", "MediumSpringGreen", "MediumTurquoise", "MediumVioletRed", "MidnightBlue", "MintCream", "MistyRose", "Moccasin", "NavajoWhite", "Navy", "OldLace", "Olive", "OliveDrab", "Orange", "OrangeRed", "Orchid", "PaleGoldenRod", "PaleGreen", "PaleTurquoise", "PaleVioletRed", "PapayaWhip", "PeachPuff", "Peru", "Pink", "Plum", "PowderBlue", "Purple", "Red", "RosyBrown", "RoyalBlue", "SaddleBrown", "Salmon", "SandyBrown", "SeaGreen", "SeaShell", "Sienna", "Silver", "SkyBlue", "SlateBlue", "SlateGray", "SlateGrey", "Snow", "SpringGreen", "SteelBlue", "Tan", "Teal", "Thistle", "Tomato", "Turquoise", "Violet", "Wheat", "White", "WhiteSmoke", "Yellow", "YellowGreen"],
        color = document.getElementById("color").value.trim(),
        rxValidHex = /^#(?:[0-9a-f]{3}){1,2}$/i,
        formattedName = color.charAt(0).toUpperCase() + color.slice(1).toLowerCase();

    if (names.indexOf(formattedName) !== -1 || rxValidHex.test(color)) {
        document.getElementById("coltext").style.color = color;
    } else {
        alert("Invalid CSS Color");
    }

SELECT DATENAME(MONTH, GETDATE()) 
         + RIGHT(CONVERT(VARCHAR(12), GETDATE(), 107), 9) AS [Month DD, YYYY]

OR Date without Comma Between date and year, you can use the following

SELECT DATENAME(MONTH, GETDATE()) + ' ' + CAST(DAY(GETDATE()) AS VARCHAR(2))
           + ' ' + CAST(YEAR(GETDATE()) AS VARCHAR(4)) AS [Month DD YYYY]

Its should work for all version of eclipse even in Spring tool suit(STS). Here is the steps

Go to the URl Follow The link to download or click the bellow link to direct download Click Here to download

Download JD-Eclipse. Download and unzip the JD-Eclipse Update Site,

Launch Eclipse,

Click on "Help > Install New Software...",

Click on button "Add..." to add an new repository,

Enter "JD-Eclipse Update Site" and select the local site directory,

Select extracted folder and give any name. I have given JDA. and click ok.

Check "Java Decompiler Eclipse Plug-in",

Next, next, next... and restart Eclipse.

You can also achieve this through aggregate pipeline.

db.collection.aggregate([{$sort:{age:-1}}, {$limit:1}])

This means that somewhere else in your code, you have something like:

sum = 0

Which shadows the builtin sum (which is callable) with an int (which isn't).

SQL is implemented as if a query was executed in the following order:

1. FROM clause
2. WHERE clause
3. GROUP BY clause
4. HAVING clause
5. SELECT clause
6. ORDER BY clause

For most relational database systems, this order explains which names (columns or aliases) are valid because they must have been introduced in a previous step.

So in Oracle and SQL Server, you cannot use a term in the GROUP BY clause that you define in the SELECT clause because the GROUP BY is executed before the SELECT clause.

There are exceptions though: MySQL and Postgres seem to have additional smartness that allows it.

The problem is that your PATH does not include the location of the node executable.

You can likely run node as "/usr/local/bin/node".

You can add that location to your path by running the following command to add a single line to your bashrc file:

echo 'export PATH=$PATH:/usr/local/bin' >> $HOME/.bashrc

This is the best solution I found so far.

Suppose we have a package called org.mypackage containing the classes:

• HelloWorld (main class)
• SupportClass
• UtilClass

and the files defining this package are stored physically under the directory D:\myprogram (on Windows) or /home/user/myprogram (on Linux).

The file structure will look like this:

When we invoke Java, we specify the name of the application to run: org.mypackage.HelloWorld. However we must also tell Java where to look for the files and directories defining our package. So to launch the program, we have to use the following command:

NOTE: You have to execute the above java command no matter what your current location is. But this is not the case for javac. For compiling you can even directly go into the directory where you have your .java files and directly execute javac ClassName.java.

Looking at this official google link: Youtube Live encoder settings, bitrates and resolutions they have this table:

                   240p       360p        480p        720p        1080p
Resolution      426 x 240   640 x 360   854x480     1280x720    1920x1080
Video Bitrates                   
Maximum         700 Kbps    1000 Kbps   2000 Kbps   4000 Kbps   6000 Kbps
Recommended     400 Kbps    750 Kbps    1000 Kbps   2500 Kbps   4500 Kbps
Minimum         300 Kbps    400 Kbps    500 Kbps    1500 Kbps   3000 Kbps

It would appear as though this is the case, although the numbers dont sync up to the google table above:

// the bitrates, video width and file names for this clip
      bitrates: [
        { url: "bbb-800.mp4", width: 480, bitrate: 800 }, //360p video
        { url: "bbb-1200.mp4", width: 720, bitrate: 1200 }, //480p video
        { url: "bbb-1600.mp4", width: 1080, bitrate: 1600 } //720p video
      ],

In this context components to me sound like isolated runtime portions of an engine that may execute concurrently with other components. If this is the motivation then you might want to look at the actor model and systems that make use of it.

The typical way to send binary in json is to base64 encode it.

Java provides different ways to Base64 encode and decode a byte[]. One of these is DatatypeConverter.

Very simply

byte[] originalBytes = new byte[] { 1, 2, 3, 4, 5};
String base64Encoded = DatatypeConverter.printBase64Binary(originalBytes);
byte[] base64Decoded = DatatypeConverter.parseBase64Binary(base64Encoded);

You'll have to make this conversion depending on the json parser/generator library you use.

i was having the same problem. and the problem was caused because i was listening to port 8080, on 2 listeners.

setMaxListeners() works fine, but i would not recommend it.

the correct way is to, check your code for extra listeners, remove the listener or change the port number on which you are listening, this fixed my problem.

that's my procedure

CREATE PROC sp_count
    @CompanyId sysname,
    @codition sysname
    AS
    SET NOCOUNT ON
    CREATE TABLE #ctr
    ( NumRows int )

    DECLARE @intCount int
         , @vcSQL varchar(255)

    SELECT    @vcSQL = ' INSERT #ctr FROM dbo.Comm_Services 
                       WHERE CompanyId = '+@CompanyId+' and '+@condition+')'
    EXEC      (@vcSQL)

    IF @@ERROR = 0
    BEGIN
         SELECT    @intCount = NumRows
         FROM #ctr

         DROP TABLE #ctr
         RETURN @intCount
    END
    ELSE
    BEGIN
         DROP TABLE #ctr

        }
    });

What you're checking

if(isset($_POST['submit']))

but there's no variable name called "submit". well i want you to understand why it doesn't works. lets imagine if you give your submit button name delete <input type="submit" value="Submit" name="delete" /> and check if(isset($_POST['delete'])) then it works in this code you didn't give any name to submit button and checking its exist or not with isset(); function so php didn't find any variable like "submit" so its not working now try this :

<input type="submit" name="submit" value="Submit" />

If your dictionary isn't too big maybe str + eval can do the work:

dict1 = {'one':1, 'two':2, 'three': {'three.1': 3.1, 'three.2': 3.2 }}
str1 = str(dict1)

dict2 = eval(str1)

print dict1==dict2

You can use ast.literal_eval instead of eval for additional security if the source is untrusted.

let blurEffect = UIBlurEffect(style: UIBlurEffect.Style.dark)
                    let blurEffectView = UIVisualEffectView(effect: blurEffect)
                    blurEffectView.backgroundColor = .black
                    blurEffectView.alpha = 0.5
                    blurEffectView.frame = topView.bounds

                        blurEffectView.frame.origin.x = -topView.frame.width
                    }
                    blurEffectView.frame.origin.x = -topView.frame.width

                        } else {
                            blurEffectView.frame.origin.x = 0
                        }
                        view.addSubview(blurEffectView)
                    } completion: { (status) in
                        
                    }

I solved the problem by saving the fragments in SparceArray:

public abstract class SaveFragmentsPagerAdapter extends FragmentPagerAdapter {

    SparseArray<Fragment> fragments = new SparseArray<>();

    public SaveFragmentsPagerAdapter(FragmentManager fm) {
        super(fm);
    }

    @Override
    public Object instantiateItem(ViewGroup container, int position) {
        Fragment fragment = (Fragment) super.instantiateItem(container, position);
        fragments.append(position, fragment);
        return fragment;
    }

    @Nullable
    public Fragment getFragmentByPosition(int position){
        return fragments.get(position);
    }

}

I would argue instead of testing i less than elements.length - 1 testing i + 1 less than elements.length. You aren't changing the domain of the array that you are looking at (i.e. ignoring the last element), but rather changing the greatest element you are looking at in each iteration.

String[] elements = { "a", "a","a","a" };

for(int i = 0; i + 1 < elements.length; i++) {
    String first = elements[i];
    String second = elements[i+1];
    //do something with the two strings
}

Per zanco's answer, you're not providing a remote command to ssh, given how the shell parses the command line. To solve this problem, change the syntax of your ssh command invocation so that the remote command is comprised of a syntactically correct, multi-line string.

There are a variety of syntaxes that can be used. For example, since commands can be piped into bash and sh, and probably other shells too, the simplest solution is to just combine ssh shell invocation with heredocs:

ssh user@server /bin/bash <<'EOT'
echo "These commands will be run on: $( uname -a )"
echo "They are executed by: $( whoami )"
EOT

Note that executing the above without /bin/bash will result in the warning Pseudo-terminal will not be allocated because stdin is not a terminal. Also note that EOT is surrounded by single-quotes, so that bash recognizes the heredoc as a nowdoc, turning off local variable interpolation so that the command text will be passed as-is to ssh.

If you are a fan of pipes, you can rewrite the above as follows:

cat <<'EOT' | ssh user@server /bin/bash
echo "These commands will be run on: $( uname -a )"
echo "They are executed by: $( whoami )"
EOT

The same caveat about /bin/bash applies to the above.

Another valid approach is to pass the multi-line remote command as a single string, using multiple layers of bash variable interpolation as follows:

ssh user@server "$( cat <<'EOT'
echo "These commands will be run on: $( uname -a )"
echo "They are executed by: $( whoami )"
EOT
)"

The solution above fixes this problem in the following manner:

1. ssh user@server is parsed by bash, and is interpreted to be the ssh command, followed by an argument user@server to be passed to the ssh command

2. " begins an interpolated string, which when completed, will comprise an argument to be passed to the ssh command, which in this case will be interpreted by ssh to be the remote command to execute as user@server

3. $( begins a command to be executed, with the output being captured by the surrounding interpolated string

4. cat is a command to output the contents of whatever file follows. The output of cat will be passed back into the capturing interpolated string

5. << begins a bash heredoc

6. 'EOT' specifies that the name of the heredoc is EOT. The single quotes ' surrounding EOT specifies that the heredoc should be parsed as a nowdoc, which is a special form of heredoc in which the contents do not get interpolated by bash, but rather passed on in literal format

7. Any content that is encountered between <<'EOT' and <newline>EOT<newline> will be appended to the nowdoc output

8. EOT terminates the nowdoc, resulting in a nowdoc temporary file being created and passed back to the calling cat command. cat outputs the nowdoc and passes the output back to the capturing interpolated string

9. ) concludes the command to be executed

10. " concludes the capturing interpolated string. The contents of the interpolated string will be passed back to ssh as a single command line argument, which ssh will interpret as the remote command to execute as user@server

If you need to avoid using external tools like cat, and don't mind having two statements instead of one, use the read built-in with a heredoc to generate the SSH command:

IFS='' read -r -d '' SSH_COMMAND <<'EOT'
echo "These commands will be run on: $( uname -a )"
echo "They are executed by: $( whoami )"
EOT

ssh user@server "${SSH_COMMAND}"

Also, If you are new and you are not using T4MVC, then I would recommend you to use it!

It gives you intellisence for actions,Controllers,views etc (no more magic strings)

You can fetch the URL in your template like this:

<p>URL of this page: {{ request.get_full_path }}</p>

or by

{{ request.path }} if you don't need the extra parameters.

Some precisions and corrections should be brought to hypete's and Igancio's answers, I'll just summarize the whole idea here, for future reference.

If you need the request variable in the template, you must add the 'django.core.context_processors.request' to the TEMPLATE_CONTEXT_PROCESSORS settings, it's not by default (Django 1.4).

You must also not forget the other context processors used by your applications. So, to add the request to the other default processors, you could add this in your settings, to avoid hard-coding the default processor list (that may very well change in later versions):

from django.conf.global_settings import TEMPLATE_CONTEXT_PROCESSORS as TCP

TEMPLATE_CONTEXT_PROCESSORS = TCP + (
    'django.core.context_processors.request',
)

Then, provided you send the request contents in your response, for example as this:

from django.shortcuts import render_to_response
from django.template import RequestContext

def index(request):
    return render_to_response(
        'user/profile.html',
        { 'title': 'User profile' },
        context_instance=RequestContext(request)
    )

I usually do a:

typedef enum {FALSE = 0, TRUE} boolean;

Type "gg" in command mode. This brings the cursor to the first line.

On Gradle 5.x I use:

wrapper {
    gradleVersion = '5.5.1'
}

I feed a 514 dimensional real-valued input to a Sequential model in Keras. My model is constructed in following way :

    predictivemodel = Sequential()
    predictivemodel.add(Dense(514, input_dim=514, W_regularizer=WeightRegularizer(l1=0.000001,l2=0.000001), init='normal'))
    predictivemodel.add(Dense(257, W_regularizer=WeightRegularizer(l1=0.000001,l2=0.000001), init='normal'))
    predictivemodel.compile(loss='mean_squared_error', optimizer='adam', metrics=['accuracy'])

When I print model.summary() I get following result:

Layer (type)    Output Shape  Param #     Connected to                   
================================================================
dense_1 (Dense) (None, 514)   264710      dense_input_1[0][0]              
________________________________________________________________
activation_1    (None, 514)   0           dense_1[0][0]

________________________________________________________________ 

For the dense_1 layer , number of params is 264710. This is obtained as : 514 (input values) * 514 (neurons in the first layer) + 514 (bias values)

For dense_2 layer, number of params is 132355. This is obtained as : 514 (input values) * 257 (neurons in the second layer) + 257 (bias values for neurons in the second layer)

use this : export MYVAR="$(dirname "$(dirname "$(dirname "$(dirname $PWD)")")")" if you want 4th parent directory

export MYVAR="$(dirname "$(dirname "$(dirname $PWD)")")" if you want 3rd parent directory

export MYVAR="$(dirname "$(dirname $PWD)")" if you want 2nd parent directory

Why does not it work? Because the background CSS with background:none!important has one #ID

A CSS selector file that contains an #id will always have a higher value than one .class

If you want to work, you need add #id on your .image-list li like this:

#an-element .image-list li {
    display: inline-block;
    background-image: url("http://placekitten.com/150/50")!important;
    padding: 1em;
    border: 1px solid blue;
}

Probably svn import would be the best option around. Check out Getting Data into Your Repository (in Version Control with Subversion, For Subversion).

The svn import command is a quick way to copy an unversioned tree of files into a repository, creating intermediate directories as necessary. svn import doesn't require a working copy, and your files are immediately committed to the repository. You typically use this when you have an existing tree of files that you want to begin tracking in your Subversion repository. For example:

$ svn import /path/to/mytree \
             http://svn.example.com/svn/repo/some/project \
             -m "Initial import"
Adding         mytree/foo.c
Adding         mytree/bar.c
Adding         mytree/subdir
Adding         mytree/subdir/quux.h

Committed revision 1.
$

The previous example copied the contents of the local directory mytree into the directory some/project in the repository. Note that you didn't have to create that new directory first—svn import does that for you. Immediately after the commit, you can see your data in the repository:

$ svn list http://svn.example.com/svn/repo/some/project
bar.c
foo.c
subdir/
$

Note that after the import is finished, the original local directory is not converted into a working copy. To begin working on that data in a versioned fashion, you still need to create a fresh working copy of that tree.

Note: if you are on the same machine as the Subversion repository you can use the file:// specifier with a path rather than the https:// with a URL specifier.

Immutable means that once the object is created, non of its members will change. String is immutable since you can not change its content. For example:

String s1 = "  abc  ";
String s2 = s1.trim();

In the code above, the string s1 did not change, another object (s2) was created using s1.

I would do it this way if you needed an instance variable of the object to work with:

if @business = Business.where(:user_id => current_user.id).first
  #Do stuff
else
  #Do stuff
end

in case of using cardviewfor rounding imageview and fixed android:layout_height for header this worked for me to load image with Glide

    <?xml version="1.0" encoding="utf-8"?>

Use these:

• username : root
• password : (nothing)

Then you will get the page you want (more options than the admin page) with privileges.

Please refer to the official Advanced Content Filter guide and plugin integration tutorial.

You'll find much more than this about this powerful feature. Also see config.extraAllowedContent that seems suitable for your needs.

If your rows are not equal you can also use map:

>>> uneven = [['a','b','c'],['d','e'],['g','h','i']]
>>> map(None,*uneven)
[('a', 'd', 'g'), ('b', 'e', 'h'), ('c', None, 'i')]

Edit: In Python 3 the functionality of map changed, itertools.zip_longest can be used instead:
Source: What’s New In Python 3.0

>>> import itertools
>>> uneven = [['a','b','c'],['d','e'],['g','h','i']]
>>> list(itertools.zip_longest(*uneven))
[('a', 'd', 'g'), ('b', 'e', 'h'), ('c', None, 'i')]

" ".join(foo.split()) is not quite correct with respect to the question asked because it also entirely removes single leading and/or trailing white spaces. So, if they shall also be replaced by 1 blank, you should do something like the following:

" ".join(('*' + foo + '*').split()) [1:-1]

Of course, it's less elegant.

You could use URL sequence substitution with a dummy query string (if you want to use CURL and save a few keystrokes):

curl http://www.myurl.com/?[1-20]

If you have other query strings in your URL, assign the sequence to a throwaway variable:

curl http://www.myurl.com/?myVar=111&fakeVar=[1-20]

Check out the URL section on the man page: https://curl.haxx.se/docs/manpage.html

Here's a very good explanation taken verbatim from http://www.paulboxley.com/blog/2011/06/git-caret-and-tilde :

ref~ is shorthand for ref~1 and means the commit's first parent. ref~2 means the commit's first parent's first parent. ref~3 means the commit's first parent's first parent's first parent. And so on.

ref^ is shorthand for ref^1 and means the commit's first parent. But where the two differ is that ref^2 means the commit's second parent (remember, commits can have two parents when they are a merge).

The ^ and ~ operators can be combined.

System.Convert.ChangeType(jtoken.ToString(), targetType);

or

JsonConvert.DeserializeObject(jtoken.ToString(), targetType);

Note: "schtasks" (see the other, accepted response) has replaced "at". However, "at" may be of use if the situation calls for compatibility with older versions of Windows that don't have schtasks.

Command-line help for "at":

C:\>at /?
The AT command schedules commands and programs to run on a computer at
a specified time and date. The Schedule service must be running to use
the AT command.

AT [\\computername] [ [id] [/DELETE] | /DELETE [/YES]]
AT [\\computername] time [/INTERACTIVE]
    [ /EVERY:date[,...] | /NEXT:date[,...]] "command"

\\computername     Specifies a remote computer. Commands are scheduled on the
                   local computer if this parameter is omitted.
id                 Is an identification number assigned to a scheduled
                   command.
/delete            Cancels a scheduled command. If id is omitted, all the
                   scheduled commands on the computer are canceled.
/yes               Used with cancel all jobs command when no further
                   confirmation is desired.
time               Specifies the time when command is to run.
/interactive       Allows the job to interact with the desktop of the user
                   who is logged on at the time the job runs.
/every:date[,...]  Runs the command on each specified day(s) of the week or
                   month. If date is omitted, the current day of the month
                   is assumed.
/next:date[,...]   Runs the specified command on the next occurrence of the
                   day (for example, next Thursday).  If date is omitted, the
                   current day of the month is assumed.
"command"          Is the Windows NT command, or batch program to be run.

A lot of these answers have similarities but are all missing the most important part which is in onActivityResult, check if data.getClipData is null before checking data.getData

The code to call the file chooser:

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("image/*"); //allows any image file type. Change * to specific extension to limit it
//**The following line is the important one!
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), SELECT_PICTURES); //SELECT_PICTURES is simply a global int used to check the calling intent in onActivityResult

The code to get all of the images selected:

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if(requestCode == SELECT_PICTURES) {
        if(resultCode == Activity.RESULT_OK) {
            if(data.getClipData() != null) {
                int count = data.getClipData().getItemCount(); //evaluate the count before the for loop --- otherwise, the count is evaluated every loop.
                for(int i = 0; i < count; i++)  
                    Uri imageUri = data.getClipData().getItemAt(i).getUri();
                    //do something with the image (save it to some directory or whatever you need to do with it here) 
                }
            } else if(data.getData() != null) {
                String imagePath = data.getData().getPath();
                //do something with the image (save it to some directory or whatever you need to do with it here)
            }
        }
    }
}

Note that Android's chooser has Photos and Gallery available on some devices. Photos allows multiple images to be selected. Gallery allows just one at a time.

In the C++ standard, cout is defined in the std namespace, so you need to either say std::cout or put

using namespace std;

in your code in order to get at it.

However, this was not always the case, and in the past cout was just in the global namespace (or, later on, in both global and std). I would therefore conclude that your classes used an older C++ compiler.

This is what I used for checking if any checkboxes in a list of checkboxes had changed:

$('input[type="checkbox"]').change(function(){ 

        var itemName = $('select option:selected').text();  

         //Do something.

});     

As a side note processes that uses virtual accounts (NT Service\MyService and IIS AppPool\MyAppPool) are still running under the "NETWORK SERVICE" account as this post suggests http://www.adopenstatic.com/cs/blogs/ken/archive/2008/01/29/15759.aspx. The only difference is that these processes are members of the "NT Service\MyService" or "IIS AppPool\MyAppPool" groups (as these are actually groups and not users). This is also the reason why the processes authenticate at the network as the machine the same way NETWORK SERVICE account does.

The way to secure access is not to depend upon this accounts not having NETWORK SERVICE privileges but to grant more permissions specifically to "NT Service\MyService" or "IIS AppPool\MyAppPool" and to remove permissions for "Users" if necessary.

If anyone has more accurate or contradictional information please post.

One way to do it must be if (typeof myObj.prop1 != "undefined") {...}

There is an issue with iOS not registering click/touch events bound to elements added after DOM loads.

While PPK has this advice: http://www.quirksmode.org/blog/archives/2010/09/click_event_del.html

I've found this the easy fix, simply add this to the css:

cursor: pointer;

For completeness sake, and for those that do not wish to use the Interface Builder, here's a way of creating the same table as in Suragch's answer entirely programatically - albeit with a different size and position.

class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource  {

    var tableView: UITableView = UITableView()
    let animals = ["Horse", "Cow", "Camel", "Sheep", "Goat"]
    let cellReuseIdentifier = "cell"

    override func viewDidLoad() {
        super.viewDidLoad()

        tableView.frame = CGRectMake(0, 50, 320, 200)
        tableView.delegate = self
        tableView.dataSource = self
        tableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: cellReuseIdentifier)

        self.view.addSubview(tableView)
    }

    func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return animals.count
    }

    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        let cell:UITableViewCell = tableView.dequeueReusableCellWithIdentifier(cellReuseIdentifier) as UITableViewCell!

        cell.textLabel?.text = animals[indexPath.row]

        return cell
    }

    func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
        print("You tapped cell number \(indexPath.row).")
    }

}

Make sure you have remembered to import UIKit.

depending on where you got that "5a', you can just append \x to it and pass to printf

$ a=5a
$ a="\x${a}"
$ printf "$a"

In your example, it’s fine as it is: it’s simple and works. The only things I’d suggest are:

1. validating the data POSTed

2. make sure your API is sending the Content-Type header to tell the client to expect a JSON response:

   header('Content-Type: application/json');
   echo json_encode($response);
   

Other than that, an API is something that takes an input and provides an output. It’s possible to “over-engineer” things, in that you make things more complicated that need be.

If you wanted to go down the route of controllers and models, then read up on the MVC pattern and work out how your domain objects fit into it. Looking at the above example, I can see maybe a MathController with an add() action/method.

There are a few starting point projects for RESTful APIs on GitHub that are worth a look.

You don't need the jsp:useBean to set the model if you already have a controller which prepared the model.

Just access it plain by EL:

<p>${Questions.questionPaperID}</p>
<p>${Questions.question}</p>

or by JSTL <c:out> tag if you'd like to HTML-escape the values or when you're still working on legacy Servlet 2.3 containers or older when EL wasn't supported in template text yet:

<p><c:out value="${Questions.questionPaperID}" /></p>
<p><c:out value="${Questions.question}" /></p>

See also:

• Our Servlets wiki page

Unrelated to the problem, the normal practice is by the way to start attribute name with a lowercase, like you do with normal variable names.

session.setAttribute("questions", questions);

and alter EL accordingly to use ${questions}.

Also note that you don't have any JSTL tag in your code. It's all plain JSP.

Windows Users need to set below paths:

• ..\Anaconda3
• ..\Anaconda3\scripts
• ..\Anaconda3\Library\bin

Per user:

1. Open Environment variable
2. Click User Variable
3. Close command prompt if already open and reopen it

System wide (requires restart):

1. Open Environment variable
2. Click System Variable
3. Restart Windows

...is there at least an easy way to check if it has a particular method other than simply checking if an error occurs when the method is called

While "Easier to ask for forgiveness than permission" is certainly the Pythonic way, you may be looking for:

d={'foo':'bar', 'spam':'eggs'}
if 'get' in dir(d):
    d.get('foo')
# OUT: 'bar'

I'm afraid there's not enough information in your question to be certain about what's going on, since you haven't replied to my follow-up question, but this may be of help in any case.

That error means that projectfolder is already staged ("already exists in the index"). To find out what's going on here, try to list everything in the index under that folder with:

git ls-files --stage projectfolder

The first column of that output will tell you what type of object is in the index at projectfolder. (These look like Unix filemodes, but have special meanings in git.)

I suspect that you will see something like:

160000 d00cf29f23627fc54eb992dde6a79112677cd86c 0   projectfolder

(i.e. a line beginning with 160000), in which case the repository in projectfolder has already been added as a "gitlink". If it doesn't appear in the output of git submodule, and you want to re-add it as a submodule, you can do:

git rm --cached projectfolder

... to unstage it, and then:

git submodule add url_to_repo projectfolder

... to add the repository as a submodule.

However, it's also possible that you will see many blobs listed (with file modes 100644 and 100755), which would suggest to me that you didn't properly unstage the files in projectfolder before copying the new repository into place. If that's the case, you can do the following to unstage all of those files:

git rm -r --cached projectfolder

... and then add the submodule with:

git submodule add url_to_repo projectfolder

The best way to do this would be to use the promise returning function as it is, like this

lookupValue(file).then(function(res) {
    // Write the code which depends on the `res.val`, here
});

The function which invokes an asynchronous function cannot wait till the async function returns a value. Because, it just invokes the async function and executes the rest of the code in it. So, when an async function returns a value, it will not be received by the same function which invoked it.

So, the general idea is to write the code which depends on the return value of an async function, in the async function itself.

Try

onsubmit="return checkRegistration()"

Check \httpdocs\bootstrap\cache\config.php file in plesk to see if there are some unwanted paths.

I just found an easy way to understand hard links in a common scenario, software install.

One day I downloaded a software to folder Downloads for install. After I did sudo make install, some executables were cped to local bin folder. Here, cp creates hard link. I was happy with the software but soon realized that Downloads isn't a good place in the long run. So I mved the software folder to source directory. Well, I can still run the software as before without worrying about any target link things, like in Windows. This means hard link finds inode directly and other files around.

I'm using this lib to access nested dict keys

https://github.com/mewwts/addict

 import requests
 from addict import Dict
 r = requests.get('http://api.zippopotam.us/us/ma/belmont')
 j = Dict(r.json())

 print j.state
 print j.places[1]['post code']  # only work with keys without '-', space, or starting with number 

Update in Intent class.

• Use hasExtra() for checking if intent has data on key.
• You can use now getStringExtra() directly.

Pass Data

intent.putExtra(PutExtraConstants.USER_NAME, "user");

Get Data

String userName;
if (getIntent().hasExtra(PutExtraConstants.USER_NAME)) {
    userName = getIntent().getStringExtra(PutExtraConstants.USER_NAME);
}

Always put keys in constants as best practice.

public interface PutExtraConstants {
    String USER_NAME = "USER_NAME";
}

In kotlin :

private fun File.writeBitmap(bitmap: Bitmap, format: Bitmap.CompressFormat, quality: Int) {
    outputStream().use { out ->
        bitmap.compress(format, quality, out)
        out.flush()
    }
}

usage example:

File(exportDir, "map.png").writeBitmap(bitmap, Bitmap.CompressFormat.PNG, 85)

Method overriding is made possible by dynamic dispatching, meaning that the declared type of an object doesn't determine its behavior, but rather its runtime type:

Animal lassie = new Dog();
lassie.speak(); // outputs "woof!"
Animal kermit = new Frog();
kermit.speak(); // outputs "ribbit!"

Even though both lassie and kermit are declared as objects of type Animal, their behavior (method .speak()) varies because dynamic dispatching will only bind the method call .speak() to an implementation at run time - not at compile time.

Now, here's where the static keyword starts to make sense: the word "static" is an antonym for "dynamic". So the reason why you can't override static methods is because there is no dynamic dispatching on static members - because static literally means "not dynamic". If they dispatched dynamically (and thus could be overriden) the static keyword just wouldn't make sense anymore.

If you don't want to use a separate JS library to create a custom control for that, you could use two confirm dialogs to do the checks:

if (confirm("Are you sure you want to quit?") ) {
    if (confirm("Save your work before leaving?") ) {
        // code here for save then leave (Yes)
    } else {
        //code here for no save but leave (No)
    }
} else {
    //code here for don't leave (Cancel)
}

Heres a another take on this problem, using recursion and without using mutable variables. Also, im not using setInterval so theres no cleanup that has to be done.

Having this HTML

<section id="testimonials">
    <h2>My testimonial spinner</h2>
    <div class="testimonial">
      <p>First content</p>
    </div>
    <div class="testimonial">
      <p>Second content</p>
    </div>
    <div class="testimonial">
       <p>Third content</p>
    </div>
</section>

Using ES2016

Here you call the function recursively and update the arguments.

  const testimonials = $('#testimonials')
      .children()
      .filter('div.testimonial');

  const showTestimonial = index => {

    testimonials.hide();
    $(testimonials[index]).fadeIn();

    return index === testimonials.length
      ? showTestimonial(0)
      : setTimeout(() => { showTestimonial(index + 1); }, 10000);
   }

showTestimonial(0); // id of the first element you want to show.

Create a separate ul.nav for just that list item and float that ul right.

jsFiddle

Since the fmt:formatNumber tag doesn't always yield the correct result, here is another JSP-only approach: It just formats the number as string and does the rest of the computation on the string, since that is easier and doesn't involve further floating point arithmetics.

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn" %>

<%
  double[] numbers = { 0.0, 3.25, 3.75, 3.5, 2.5, -1.5, -2.5 };
  pageContext.setAttribute("numbers", numbers);
%>

<html>
  <body>
    <ul>
      <c:forEach var="n" items="${numbers}">
        <li>${n} = ${fn:substringBefore(n, ".")} + ${n - fn:substringBefore(n, ".")}</li>
      </c:forEach>
    </ul>
  </body>
</html>

This is really linked to HotSpot and the default option values (Java HotSpot VM Options) which differ between client and server configuration.

From Chapter 2 of the whitepaper (The Java HotSpot Performance Engine Architecture):

The JDK includes two flavors of the VM -- a client-side offering, and a VM tuned for server applications. These two solutions share the Java HotSpot runtime environment code base, but use different compilers that are suited to the distinctly unique performance characteristics of clients and servers. These differences include the compilation inlining policy and heap defaults.

Although the Server and the Client VMs are similar, the Server VM has been specially tuned to maximize peak operating speed. It is intended for executing long-running server applications, which need the fastest possible operating speed more than a fast start-up time or smaller runtime memory footprint.

The Client VM compiler serves as an upgrade for both the Classic VM and the just-in-time (JIT) compilers used by previous versions of the JDK. The Client VM offers improved run time performance for applications and applets. The Java HotSpot Client VM has been specially tuned to reduce application start-up time and memory footprint, making it particularly well suited for client environments. In general, the client system is better for GUIs.

So the real difference is also on the compiler level:

The Client VM compiler does not try to execute many of the more complex optimizations performed by the compiler in the Server VM, but in exchange, it requires less time to analyze and compile a piece of code. This means the Client VM can start up faster and requires a smaller memory footprint.

The Server VM contains an advanced adaptive compiler that supports many of the same types of optimizations performed by optimizing C++ compilers, as well as some optimizations that cannot be done by traditional compilers, such as aggressive inlining across virtual method invocations. This is a competitive and performance advantage over static compilers. Adaptive optimization technology is very flexible in its approach, and typically outperforms even advanced static analysis and compilation techniques.

Note: The release of jdk6 update 10 (see Update Release Notes:Changes in 1.6.0_10) tried to improve startup time, but for a different reason than the hotspot options, being packaged differently with a much smaller kernel.

G. Demecki points out in the comments that in 64-bit versions of JDK, the -client option is ignored for many years.
See Windows java command:

-client

Selects the Java HotSpot Client VM.
A 64-bit capable JDK currently ignores this option and instead uses the Java Hotspot Server VM.

Here's what I ended up using.

I'm very new to AngularJS, so would love to see better / alternative solutions.

angular.module('formComponents', [])
    .directive('formInput', function() {
        return {
            restrict: 'E',
            scope: {},
            link: function(scope, element, attrs)
            {
                var type = attrs.type || 'text';
                var required = attrs.hasOwnProperty('required') ? "required='required'" : "";
                var htmlText = '<div class="control-group">' +
                    '<label class="control-label" for="' + attrs.formId + '">' + attrs.label + '</label>' +
                        '<div class="controls">' +
                        '<input type="' + type + '" class="input-xlarge" id="' + attrs.formId + '" name="' + attrs.formId + '" ' + required + '>' +
                        '</div>' +
                    '</div>';
                element.html(htmlText);
            }
        }
    })

Example usage:

<form-input label="Application Name" form-id="appName" required/></form-input>
<form-input type="email" label="Email address" form-id="emailAddress" required/></form-input>
<form-input type="password" label="Password" form-id="password" /></form-input>

The problem was the box "open new connection" that was checked. So I couldn't use my temporary table.

Take a look at the FormBorderStyle property

form1.FormBorderStyle = FormBorderStyle.FixedSingle;

You may also want to remove the minimize and maximize buttons:

form1.MaximizeBox = false;
form1.MinimizeBox = false;

If you are using Spring Boot, then add thymeleaf dependency into your pom.xml:

    <dependency>
        <groupId>org.thymeleaf</groupId>
        <artifactId>thymeleaf-spring4</artifactId>
        <version>2.1.6.RELEASE</version>
    </dependency>

You should take it simple here you go :

first you have the initial position of your text or button :

<div style="background-color:green; height:200px; width:400px; margin:0 0 0 35%;">
   <h2> Simple Text </h2>
      <div>
           <button> Simple Button </button>
      </div>
</div>

By adding this css code line to the h2 tag or to the div tag that holds the button tag

style:" text-align:center; "

Finaly The result code will be :

<div style="background-color:green; height:200px; width:400px; margin:0 0 0 35%;">
<h2 style="text-align:center;"> Simple Text </h2> <!-- <<--- here the changes -->

      <div style="text-align:center">        <!-- <<--- here the changes -->
                <button> Simple Button </button>
      </div>
</div>
