new[,2] is a factor, not a numeric vector. Transform it first

new$MY_NEW_COLUMN <-as.numeric(as.character(new[,2])) * 5

Escape sequences must be interpreted by SOMETHING to be converted to color. The standard CMD.EXE used by java when started from the command line, doesn't support this so therefore Java does not.

My solution was to change the run configurations module drop-down list from wearable to android. (This error happened to me when I tried running Google's I/O Sched open-source app.) It would automatically pop up the configurations every time I tried to run until I changed the module to android.

You can access the configurations by going to Run -> Edit Configurations... -> General tab -> Module: [drop-down-list-here]

While all the answers are perfectly fine, I was looking for a way to test if a function raised an exception without relying on unit testing frameworks and having to write test classes.

I ended up writing the following:

def assert_error(e, x):
    try:
        e(x)
    except:
        return
    raise AssertionError()

def failing_function(x):
    raise ValueError()

def dummy_function(x):
    return x

if __name__=="__main__":
    assert_error(failing_function, 0)
    assert_error(dummy_function, 0)

And it fails on the right line :

Traceback (most recent call last):
  File "assert_error.py", line 16, in <module>
    assert_error(dummy_function, 0)
  File "assert_error.py", line 6, in assert_error
    raise AssertionError()
AssertionError

Or you could simply use

View.isShown()

Add the right lines this way and and the horizontal borders using HR or border-bottom or .col-right-line:after. Don't forget media queries to get rid of the lines on small devices.

.col-right-line:before {
  position: absolute;
  content: " ";
  top: 0;
  right: 0;
  height: 100%;
  width: 1px;
  background-color: @color-neutral;
}

Look for a little clipboard icon that pops up at the end of the material you pasted. Click on this and choose "keep text only".

As defer attribute works only with scripts tag with src. Found a way to mimic defer for inline scripts. Use DOMContentLoaded event.

<script defer src="external-script.js"></script>
<script>
document.addEventListener("DOMContentLoaded", function(event) {
    // Your inline scripts which uses methods from external-scripts.
});
</script>

This is because, DOMContentLoaded event fires after defer attributed scripts are completely loaded.

Here's a guy that posted his Eclipse preferences for changing the colors like a theme:

http://blog.codefront.net/2006/09/28/vibrant-ink-textmate-theme-for-eclipse/

And here's more about how to set the colors in the Ganymede Eclipse version (v. 3.4, mid 2008):

http://help.eclipse.org/ganymede/index.jsp?topic=/org.eclipse.platform.doc.user/concepts/accessibility/fontsandcolors.htm

Is this what you are looking for? Here is a fiddle demo.

The layout is based on percentage, colors are for clarity. If the content column overflows, a scrollbar should appear.

body, html, .container-fluid {
  height: 100%;
}

.navbar {
  width:100%;
  background:yellow;
}

.article-tree {
  height:100%;
  width: 25%;
  float:left;
  background: pink;
}

.content-area {
  overflow: auto;
  height: 100%;
  background:orange;
}

.footer {
   background: red;
   width:100%;
   height: 20px;
}

This has been possible since the queryset-refactor branch landed pre-1.0. Ticket 4088 exposed the problem. This should work:

Asset.objects.filter(
    desc__contains=filter,
    project__name__contains="Foo").order_by("desc")

The Django Many-to-one documentation has this and other examples of following Foreign Keys using the Model API.

You can use:

Me.Close

Application.Exit

End

Process immediately terminated in Task Manager Processors!

Just put in some quotes to escape the wildcard:

unzip "*.zip"

It seems as though there are multiple rows in the DATA.Dim_Member table per SUSP.Susp_Visits row.

you must implement IComparer interface.

In this sample I've my custom object JSONReturn, I implement my class like this :

Friend Class JSONReturnComparer
    Implements IComparer(of JSONReturn)

    Public Function Compare(x As JSONReturn, y As JSONReturn) As Integer Implements    IComparer(Of JSONReturn).Compare
        Return String.Compare(x.Name, y.Name)
    End Function

End Class

I call my sort List method like this : alResult.Sort(new JSONReturnComparer())

Maybe it could help you

You can only return one value, but it can be an object that has multiple fields - ie a "value object". Eg

public class MyResult {
    int returnCode;
    String errorMessage;
    // etc
}

public MyResult someMethod() {
    // impl here
}

It is “old-fashioned” way to specify ranges of revisions you wish to merge. With 1.5+ you can use:

svn merge HEAD url/of/trunk path/to/branch/wc

A little googling, gives me these results:

RewriteEngine On
RewriteBase /
RewriteRule ^index.(.*)?$ http://domain.com/subfolder/ [r=301]

This will redirect any attempt to access a file named index.something to your subfolder, whether the file exists or not.

Or try this:

RewriteCond %{HTTP_HOST} !^www.sample.com$ [NC]
RewriteRule ^(.*)$ %{HTTP_HOST}/samlse/$1 [R=301,L]

I haven't done much redirect in the .htaccess file, so I'm not sure if this will work.

This is a checkbox you can't change:

<input type="checkbox" disabled="disabled" checked="checked">

Just add disabled="disabled" as an attribute.

Edit to address the comments:

If you want the data to be posted back, than a simple solutions is to apply the same name to a hidden input:

<input name="myvalue" type="checkbox" disabled="disabled" checked="checked"/>
<input name="myvalue" type="hidden" value="true"/>

This way, when the checkbox is set to 'disabled', it only serves the purpose of a visual representation of the data, instead of actually being 'linked' to the data. In the post back, the value of the hidden input is being sent when the checkbox is disabled.

As suggested in a similar question, use JavaScript to call window.open with the target argument set to _system, as per the InAppBrowser documentation:

<a href="#" onclick="window.open('http://www.kidzout.com', '_system'); return false;">www.kidzout.com</a>

This should work, though a better and more flexible solution would be to intercept all links' click events, and call window.open with arguments read from the link's attributes.

Remember you must install the InAppBrowser plugin for this to work:

cordova plugin add cordova-plugin-inappbrowser

Have you tried what is on the sample. I am new to this but here is the command: puppet --test --trace --debug. I hope this helps.

if you are using inline coding in single page and not using oops than go with this full example, it will sure help

//connect to the db
$dbh = new PDO('mysql:host=localhost;dbname=mydb', dbuser, dbpw); 

//build the query
$query="SELECT field1, field2
FROM ubertable
WHERE field1 > 6969";

//execute the query
$data = $dbh->query($query);
//convert result resource to array
$result = $data->fetchAll(PDO::FETCH_ASSOC);

//view the entire array (for testing)
print_r($result);

//display array elements
foreach($result as $output) {
echo output[field1] . " " . output[field1] . "<br />";
}

What worked for me was echo $testVar | tr "\n" " "

Where testVar contained my variable/script-output

Check the path of the file to be read. My code kept on giving me errors until I changed the path name to present working directory. The error was:

newchars, decodedbytes = self.decode(data, self.errors)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte

A few things:

First, I don't think you really need a validation error for a radio fieldset because you could just have one of the fields checked by default. Most people would rather correct something then provide something. For instance:

   Age: (*) 12 - 18 | () 19 - 30 | 31 - 50 

is more likely to be changed to the right answer as the person DOESN'T want it to go to the default. If they see it blank, they are more likely to think "none of your business" and skip it.

Second, I was able to get the effect I think you are wanting without any positioning properties. You just add padding-right to the form (or the div of the form, whatever) to provide enough room for your error and make sure your error will fit in that area. Then, you have a pre-set up css class called "error" and you set it as having a negative margin-top roughly the height of your input field and a margin-left about the distance from the left to where your padding-right should start. I tried this out, it's not great, but it works with three properties and requires no floats or absolutes:

   <style type="text/css">
    .error {
        width: 13em; /* Ensures that the div won't exceed right padding of form */
        margin-top: -1.5em;  /*Moves the div up to the same level as input */
        margin-left: 11em;   /*Moves div to the right */
        font-size: .9em;     /*Makes sure that the error div is smaller than input */
    }

   <form>
   <label for="name">Name:</label><input id="name" type="textbox" />
   <div class="error"><<< This field is required!</div>
   <label for="numb">Phone:</label><input id="numb" type="textbox" />
   <div class="error"><<< This field is required!</div>
   </form>

I also had this same problem.

I build .apk file of the project and installed it into mobile(android) and got it working

If you code your x axis text categories, list them in a single column, then in adjacent columns list plot points for respective variables against relevant text category code and just leave blank cells against non-relevant text category code, you can scatter plot and get the displayed result. Any questions let me know.

var results = from p in persons
              group p by p.PersonID into g
              select new { PersonID = g.Key,
                           /**/car = g.Select(g=>g.car).FirstOrDefault()/**/}

I had a similar issue with django 3.0, according migrations section in the official documentation, running this was enough to update my table structure:

python manage.py makemigrations
python manage.py migrate

But the output was always the same: 'no change detected' about my models after I executed 'makemigrations' script. I had a syntax error on models.py at the model I wanted to update on db:

field_model : models.CharField(max_length=255, ...)

instead of:

field_model = models.CharField(max_length=255, ...)

Solving this stupid mistake, with those command the migration was done without problems. Maybe this helps someone.

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

In Access, there are two types:

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

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

Minor quibble with the answers:

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

  ?Me!MyCheckBox.Value
  ?Me!MyCheckBox

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

  If Me!MyCheckBox Then

...write one of these options:

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

  If Me!MyCheckBox = True Then

  If (Me!MyCheckBox = True) Then

  If (Me!MyCheckBox = Not False) Then

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

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

In my case the format set in Preferences/Database/NLS was [Date Format] = RRRR-MM-DD HH24:MI:SSXFF but in grid there were seen 8probably default format RRRR/MM/DD (even without time) The format has changed after changing the setting [Date Format] to: RRRR-MM-DD HH24:MI:SS (without 'XFF' at the end).

There were no errors, but format with xff at the end didn't work.

Note: in polish notation RRRR means YYYY

1. right click the highlight whose color you want to change

It seems many users are having issues with this. Here are some fixes:

• Right click on your task > "Properties" > "Actions" > "Edit" | Put ONLY the file name under 'Program/Script', no quotes and ONLY the directory under 'Start in' as described, again no quotes.

• Right click on your task > "Properties" > "General" | Test with any/all of the following:

  1. "Run with highest privileges" (test both options)
  2. "Run wheter user is logged on or not" (test both options)
  3. Check that "Configure for" is set to your machine's OS version
  4. Make sure the user account running the program has the right permissions

function sanitize($string,$dbmin,$dbmax){
$string = preg_replace('#[^a-z0-9]#i', '', $string); //useful for strict cleanse, alphanumeric here
$string = mysqli_real_escape_string($con, $string); //get ready for db
if(strlen($string) > $dbmax || strlen($string) < $dbmin){
    echo "reject_this"; exit();
    }
return $string;
}

.NET List data structure is an Array in a "mutable shell".

So you can use indexes for accessing to it's elements like:

var firstElement = myList[0];
var secondElement = myList[1];

Starting with C# 8.0 you can use Index and Range classes for accessing elements. They provides accessing from the end of sequence or just access a specific part of sequence:

var lastElement = myList[^1]; // Using Index
var fiveElements = myList[2..7]; // Using Range, note that 7 is exclusive

You can combine indexes and ranges together:

var elementsFromThirdToEnd = myList[2..^0]; // Index and Range together

Also you can use LINQ ElementAt method but for 99% of cases this is really not necessary and just slow performance solution.

i use "Versions", quite easy, but not free .

You can get div content using .text() in jquery

var divContent = $('#field-function_purpose').text();
console.log(divContent);

Fiddle

If you are making the boolean column as not null then the default 'default' value is false; you don't have to explicitly specify it.

Which one is faster depends on the number of queries fetched by the inner query:

• When your inner query fetching thousand of rows then EXIST would be better choice
• When your inner query fetching few rows, then IN will be faster

EXIST evaluate on true or false but IN compare multiple value. When you don't know the record is exist or not, your should choose EXIST

I guess the issue here is that you are updating INV_DISCOUNT and the INV_TOTAL uses the INV_DISCOUNT. so that is the issue here. You can use returning clause of update statement to use the new INV_DISCOUNT and use it to update INV_TOTAL.

this is a generic example let me know if this explains the point i mentioned

CREATE OR REPLACE PROCEDURE SingleRowUpdateReturn
IS
    empName VARCHAR2(50);
    empSalary NUMBER(7,2);      
BEGIN
    UPDATE emp
    SET sal = sal + 1000
    WHERE empno = 7499
    RETURNING ename, sal
    INTO empName, empSalary;

    DBMS_OUTPUT.put_line('Name of Employee: ' || empName);
    DBMS_OUTPUT.put_line('New Salary: ' || empSalary);
END;

Say P7 is a Cell then you can use the following Syntex to check the value of the cell and assign appropriate value to another cell based on this following nested if:

=IF(P7=0,200,IF(P7=1,100,IF(P7=2,25,IF(P7=3,10,IF((P7=4),5,0)))))

Here is example code you could run to make such test:

var f = 10000000;
var p = new int[f];

for(int i = 0; i < f; ++i)
{
    p[i] = i % 2;
}

var time = DateTime.Now;
p.Sum();
Console.WriteLine(DateTime.Now - time);

int x = 0;
time = DateTime.Now;
foreach(var item in p){
   x += item;
}
Console.WriteLine(DateTime.Now - time);

x = 0;
time = DateTime.Now;
for(int i = 0, j = f; i < j; ++i){
   x += p[i];
}
Console.WriteLine(DateTime.Now - time);

The same example for complex object is:

void Main()
{
    var f = 10000000;
    var p = new Test[f];

    for(int i = 0; i < f; ++i)
    {
        p[i] = new Test();
        p[i].Property = i % 2;
    }

    var time = DateTime.Now;
    p.Sum(k => k.Property);
    Console.WriteLine(DateTime.Now - time);

    int x = 0;
    time = DateTime.Now;
    foreach(var item in p){
        x += item.Property;
    }
    Console.WriteLine(DateTime.Now - time);

    x = 0;
    time = DateTime.Now;
    for(int i = 0, j = f; i < j; ++i){
        x += p[i].Property;
    }
    Console.WriteLine(DateTime.Now - time);
}

class Test
{
    public int Property { get; set; }
}

My results with compiler optimizations off are:

00:00:00.0570370 : Sum()
00:00:00.0250180 : Foreach()
00:00:00.0430272 : For(...)

and for second test are:

00:00:00.1450955 : Sum()
00:00:00.0650430 : Foreach()
00:00:00.0690510 : For()

it looks like LINQ is generally slower than foreach(...) but what is weird for me is that foreach(...) appears to be faster than for loop.

Faced similar issue with other samples, this Kotlin class worked for me

import okhttp3.Interceptor
import okhttp3.Response

class CustomInterceptor : Interceptor {
    override fun intercept(chain: Interceptor.Chain) : Response {               
        val request = chain.request().newBuilder()
            .header("x-custom-header", "my-value")
            .build()
        return chain.proceed(request)
    }
}

SQL Server requires subqueries that you SELECT FROM or JOIN to have an alias.

Add an alias to your subquery (in this case x):

select COUNT(*) from
(
select m.Company_id
from Monitor as m
    inner join Monitor_Request as mr on mr.Company_ID=m.Company_id
    group by m.Company_id
    having COUNT(m.Monitor_id)>=5)  x

I suggest this discriminative question:

What is the best approach to do this JAVA?

I would personally NOT use Axis 2, even for client side development only. Here is why I stay away from it:

1. I don't like its architecture and hate its counter productive deployment model.
2. I find it to be low quality project.
3. I don't like its performances (see this benchmark against JAX-WS RI).
4. It's always a nightmare to setup dependencies (I use Maven and I always have to fight with the gazillion of dependencies) (see #2)
5. Axis sucked big time and Axis2 isn't better. No, this is not a personal opinion, there is a consensus.
6. I suffered once, never again.

The only reason Axis is still around is IMO because it's used in Eclipse since ages. Thanks god, this has been fixed in Eclipse Helios and I hope Axis2 will finally die. There are just much better stacks.

I read about SAAJ, looks like that will be more granular level of approach?

To do what?

Is there any other way than using the WSDL2Java tool, to generate the code. Maybe wsimport in another option. What are the pros and cons?

Yes! Prefer a JAX-WS stack like CXF or JAX-WS RI (you might also read about Metro, Metro = JAX-WS RI + WSIT), they are just more elegant, simpler, easier to use. In your case, I would just use JAX-WS RI which is included in Java 6 and thus wsimport.

Can someone send the links for some good tutorials on these topics?

That's another pro, there are plenty of (good quality) tutorials for JAX-WS, see for example:

• Developing JAX-WS Web Service Clients (start here)
• Introducing JAX-WS 2.0 With the Java SE 6 Platform, Part 1
• Creating a Simple Web Service and Client with JAX-WS
• Creating a SOAP client with either Apache CXF or GlassFish Metro (Glen Mazza's blog is a great resources)

What are the options we need to use while generating the code using the WSDL2Java?

No options, use wsimport :)

If you scale 1600x900 to 1280x720 you have

scale_x = 1280.0/1600
scale_y = 720.0/900

Then you can use it to find button size, and button position

button_width  = 300 * scale_x
button_height = 300 * scale_y

button_x = 1440 * scale_x
button_y = 860  * scale_y

If you scale 1280x720 to 1600x900 you have

scale_x = 1600.0/1280
scale_y = 900.0/720

and rest is the same.

I add .0 to value to make float - otherwise scale_x, scale_y will be rounded to integer - in this example to 0 (zero) (Python 2.x)

Here is a one line lambda that also works:

df["TrueFalse"] = df['col1'].apply(lambda x: 1 if any(i in x for i in searchfor) else 0)

Input:

searchfor = ['og', 'at']

df = pd.DataFrame([('cat', 1000.0), ('hat', 2000000.0), ('dog', 1000.0), ('fog', 330000.0),('pet', 330000.0)], columns=['col1', 'col2'])

   col1  col2
0   cat 1000.0
1   hat 2000000.0
2   dog 1000.0
3   fog 330000.0
4   pet 330000.0

Apply Lambda:

df["TrueFalse"] = df['col1'].apply(lambda x: 1 if any(i in x for i in searchfor) else 0)

Output:

    col1    col2        TrueFalse
0   cat     1000.0      1
1   hat     2000000.0   1
2   dog     1000.0      1
3   fog     330000.0    1
4   pet     330000.0    0

After the 5.7.18 version of MySQL, it does not provide the default configuration file in support-files directory. So you can create my.cnf file manually in the location where MySQL will read, like /etc/mysql/my.cnf, and add the configuration you want to add in the file.

To cross-correlate 1d arrays use numpy.correlate.

For 2d arrays, use scipy.signal.correlate2d.

There is also scipy.stsci.convolve.correlate2d.

There is also matplotlib.pyplot.xcorr which is based on numpy.correlate.

See this post on the SciPy mailing list for some links to different implementations.

Edit: @user333700 added a link to the SciPy ticket for this issue in a comment.

I don't seem to have enough rep to close this as a duplicate, but it is one if someone else can do that. I posted the same thing over at A more pretty/informative Var_dump alternative in PHP? but for the sake of saving time, I'll copy/paste it here too:

I had to add another answer here because I didn't really want to go through the steps in the other solutions. It is extremely simple and requires no extensions, includes etc and is what I prefer. It's very easy and very fast.

First just json_encode the variable in question:

echo json_encode($theResult);

Copy the result you get into the JSON Editor at http://jsoneditoronline.org/ just copy it into the left side pane, click Copy > and it pretty prints the JSON in a really nice tree format.

To each their own, but hopefully this helps some others have one more nice option! :)

Something like:

function populate(selector) {
  $(selector)
    .append('<option value="foo">foo</option>')
    .append('<option value="bar">bar</option>')
}

populate('#myform .myselect');

Or even:

$.fn.populate = function() {
  $(this)

If you would like to add vector to itself both popular solutions will fail:

std::vector<std::string> v, orig;

orig.push_back("first");
orig.push_back("second");

// BAD:
v = orig;
v.insert(v.end(), v.begin(), v.end());
// Now v contains: { "first", "second", "", "" }

// BAD:
v = orig;
std::copy(v.begin(), v.end(), std::back_inserter(v));
// std::bad_alloc exception is generated

// GOOD, but I can't guarantee it will work with any STL:
v = orig;
v.reserve(v.size()*2);
v.insert(v.end(), v.begin(), v.end());
// Now v contains: { "first", "second", "first", "second" }

// GOOD, but I can't guarantee it will work with any STL:
v = orig;
v.reserve(v.size()*2);
std::copy(v.begin(), v.end(), std::back_inserter(v));
// Now v contains: { "first", "second", "first", "second" }

// GOOD (best):
v = orig;
v.insert(v.end(), orig.begin(), orig.end()); // note: we use different vectors here
// Now v contains: { "first", "second", "first", "second" }

My silly mistake was that I forgot to add /add when requiring the observable.

Was:

import { Observable } from 'rxjs/Observable';
import 'rxjs/observable/of';

Which visually looks OK becasue rxjs/observable/of file, in fact, exists.

Should be:

import { Observable } from 'rxjs/Observable';
import 'rxjs/add/observable/of';

Understand this has been solved, but the solution provided above might not work in all situation.

For my case,

<div style="height: 490px; position:relative; overflow:hidden">
    <div id="map-canvas"></div>
</div>

Create key-value pairs within a foreach like this:

function createOfferUrlArray($Offer) {
    $offerArray = array();

    foreach ($Offer as $key => $value) {
        $offerArray[$key] = $value[4];
    }

    return $offerArray;
}

There is a undocumented timeout between when you first redirect the user to the google authentication page (and get back a code), and when you take the returned code and post it to the token url. It works fine for me with the actual google supplied client_id as opposed to an "undocumented email address". I just needed to start the process again.

I had the same issue. I found that ipython must be running for jupyter notebook to execute. Do the following:

• Go to the folder where you have your ipython notebook(.ipynb)
• Press shift and right click on the empty space then select "open command window here". This will open a command prompt window.
• Type ipython. This will start ipython.
• Open another command prompt window and open jupyter notebook.
• Open your file again and go to cell>>>run cell.

This should work. It worked for me. Cheers!

You have to use Javascript since code behind is server side only. I am pretty sure that this works.

<asp:Button ID="btnNewEntry" runat="Server" CssClass="button" Text="New Entry" OnClick="btnNewEntry_Click" OnClientClick="aspnetForm.target ='_blank';"/>

protected void btnNewEntry_Click(object sender, EventArgs e)
{
  Response.Redirect("New.aspx");
}

I noticed that I was getting this error, because my HTML code did not have <body> tag.

Without a <body>, when document.body.appendChild(form); statement did not have a body object to append.

The money-back guaranteed, reinforced-concrete-solid way to force a view to draw synchronously (before returning to the calling code) is to configure the CALayer's interactions with your UIView subclass.

In your UIView subclass, create a displayNow() method that tells the layer to “set course for display” then to “make it so”:

_Swift

/// Redraws the view's contents immediately.
/// Serves the same purpose as the display method in GLKView.
public func displayNow()
{
    let layer = self.layer
    layer.setNeedsDisplay()
    layer.displayIfNeeded()
}

_Objective-C

/// Redraws the view's contents immediately.
/// Serves the same purpose as the display method in GLKView.
- (void)displayNow
{
    CALayer *layer = self.layer;
    [layer setNeedsDisplay];
    [layer displayIfNeeded];
}

Also implement a draw(_: CALayer, in: CGContext) method that'll call your private/internal drawing method (which works since every UIView is a CALayerDelegate):

_Swift

/// Called by our CALayer when it wants us to draw
///     (in compliance with the CALayerDelegate protocol).
override func draw(_ layer: CALayer, in context: CGContext)
{
    UIGraphicsPushContext(context)
    internalDraw(self.bounds)
    UIGraphicsPopContext()
}

_Objective-C

/// Called by our CALayer when it wants us to draw
///     (in compliance with the CALayerDelegate protocol).
- (void)drawLayer:(CALayer *)layer inContext:(CGContextRef)context
{
    UIGraphicsPushContext(context);
    [self internalDrawWithRect:self.bounds];
    UIGraphicsPopContext();
}

And create your custom internalDraw(_: CGRect) method, along with fail-safe draw(_: CGRect):

_Swift

/// Internal drawing method; naming's up to you.
func internalDraw(_ rect: CGRect)
{
    // @FILLIN: Custom drawing code goes here.
    //  (Use `UIGraphicsGetCurrentContext()` where necessary.)
}

/// For compatibility, if something besides our display method asks for draw.
override func draw(_ rect: CGRect) {
    internalDraw(rect)
}

_Objective-C

/// Internal drawing method; naming's up to you.
- (void)internalDrawWithRect:(CGRect)rect
{
    // @FILLIN: Custom drawing code goes here.
    //  (Use `UIGraphicsGetCurrentContext()` where necessary.)
}

/// For compatibility, if something besides our display method asks for draw.
- (void)drawRect:(CGRect)rect {
    [self internalDrawWithRect:rect];
}

And now just call myView.displayNow() whenever you really-really need it to draw (such as from a CADisplayLink callback).  Our displayNow() method will tell the CALayer to displayIfNeeded(), which will synchronously call back into our draw(_:,in:) and do the drawing in internalDraw(_:), updating the visual with what's drawn into the context before moving on.

This approach is similar to @RobNapier's above, but has the advantage of calling displayIfNeeded() in addition to setNeedsDisplay(), which makes it synchronous.

This is possible because CALayers expose more drawing functionality than UIViews do— layers are lower-level than views and designed explicitly for the purpose of highly-configurable drawing within the layout, and (like many things in Cocoa) are designed to be used flexibly (as a parent class, or as a delegator, or as a bridge to other drawing systems, or just on their own). Proper usage of the CALayerDelegate protocol makes all this possible.

More information about the configurability of CALayers can be found in the Setting Up Layer Objects section of the Core Animation Programming Guide.

If you're using the Prototype JavaScript framework then you can use the focusFirstElement method:

Form.focusFirstElement(document.forms[0]);

session_start();
echo '<pre>';var_dump($_SESSION);echo '</pre>';
// or
echo '<pre>';print_r($_SESSION);echo '</pre>';

NOTE: session_start(); line is must then only you will able to print the value $_SESSION

Besides fall-through, it's also possible to step over by using goto. It's very useful if you want to see the world burn.

<?php

class A_Error extends Exception {}
class B_Error extends Exception {}
class C_Error extends Exception {}

try {
    throw new A_Error();
} 
catch (A_Error $e) { goto abc; }
catch (B_Error $e) { goto abc; }
catch (C_Error $e) {
abc:
    var_dump(get_class($e));
    echo "Gotta Catch 'Em All\n";
}

3v4l.org

this code works and dont throw any exception:

Session.Abandon();  
Session["tempKey1"] = "tempValue1";

It's because when the Abandon method is called, the current Session object is queued for deletion but is not actually deleted until all of the script commands on the current page have been processed. This means that you can access variables stored in the Session object on the same page as the call to the Abandon method but not in any subsequent Web pages.

For example, in the following script, the third line prints the value Mary. This is because the Session object is not destroyed until the server has finished processing the script.

<% 
  Session.Abandon  
  Session("MyName") = "Mary" 
  Reponse.Write(Session("MyName")) 
%>

If you access the variable MyName on a subsequent Web page, it is empty. This is because MyName was destroyed with the previous Session object when the page containing the previous example finished processing.

from MSDN Session.Abandon

Returning the correct format is done by the media-type formatter. As others mentioned, you can do this in the WebApiConfig class:

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        ...

        // Configure Web API to return JSON
        config.Formatters.JsonFormatter
        .SupportedMediaTypes.Add(new System.Net.Http.Headers.MediaTypeHeaderValue("text/html"));

        ...
    }
}

For more, check:

• Media Formatters in ASP.NET Web API 2.
• Content Negotiation in ASP.NET Web API.

In case your actions are returning XML (which is the case by default) and you need just a specific method to return JSON, you can then use an ActionFilterAttribute and apply it to that specific action.

Filter attribute:

public class JsonOutputAttribute : ActionFilterAttribute
{
    public override void OnActionExecuted(HttpActionExecutedContext actionExecutedContext)
    {
        ObjectContent content = actionExecutedContext.Response.Content as ObjectContent;
        var value = content.Value;
        Type targetType = actionExecutedContext.Response.Content.GetType().GetGenericArguments()[0];

        var httpResponseMsg = new HttpResponseMessage
        {
            StatusCode = HttpStatusCode.OK,
            RequestMessage = actionExecutedContext.Request,
            Content = new ObjectContent(targetType, value, new JsonMediaTypeFormatter(), (string)null)
        };

        actionExecutedContext.Response = httpResponseMsg;
        base.OnActionExecuted(actionExecutedContext);
    }
}

Applying to action:

[JsonOutput]
public IEnumerable<Person> GetPersons()
{
    return _repository.AllPersons(); // the returned output will be in JSON
}

Note that you can omit the word Attribute on the action decoration and use just [JsonOutput] instead of [JsonOutputAttribute].

I was looking to do the same thing, but to preserve the list as a just an array of strings so I wrote a new code, which from what I've been reading may not be the most efficient but worked for what i needed to do:

combineListsAsOne <-function(list1, list2){
  n <- c()
  for(x in list1){
    n<-c(n, x)
  }
  for(y in list2){
    n<-c(n, y)
  }
  return(n)
}

It just creates a new list and adds items from two supplied lists to create one.

Just hook up the onclick event:

<input id="button" type="submit" name="button" value="enter" onclick="myFunction();"/>

Here is an updated solution for Java8, using lambdas and streams:

System.out.println(list.stream()
                       .map(Object::toString)
                       .collect(Collectors.joining("\n")));

Or, without joining the list into one large string:

list.stream().forEach(System.out::println);

To find menu items in content page base on roles

 protected void Page_Load(object sender, EventArgs e)
{
   if (Session["AdminSuccess"] != null)
        {
           Menu mainMenu = (Menu)Page.Master.FindControl("NavigationMenu");

    //you must know the index of items to be removed first
    mainMenu.Items.RemoveAt(1);

    //or you try to hide menu and list items inside menu with css 
    // cssclass must be defined in style tag in .aspx page
    mainMenu.CssClass = ".hide";

        }   

}

<style type="text/css">
.hide
    {
        visibility: hidden;
     }
  </style>  

In case your DateTime has also hour:minutes:seconds and you still want to have the number of days..

   /**
     * Returns the total number of days between to DateTimes, 
     * if it is within the same year
     * @param $start
     * @param $end
     */
    public function dateTimesToDays($start,$end){
       return intval($end->format('z')) - intval($start->format('z')) + 1;
    }

It most likely means the hostname can't be resolved.

import socket
socket.getaddrinfo('localhost', 8080)

If it doesn't work there, it's not going to work in the Bottle example. You can try '127.0.0.1' instead of 'localhost' in case that's the problem.

On windows I used the following command

Neither way is necessarily correct or incorrect, they are just two different kinds of class elements:

• Elements outside the __init__ method are static elements; they belong to the class.
• Elements inside the __init__ method are elements of the object (self); they don't belong to the class.

You'll see it more clearly with some code:

class MyClass:
    static_elem = 123

    def __init__(self):
        self.object_elem = 456

c1 = MyClass()
c2 = MyClass()

# Initial values of both elements
>>> print c1.static_elem, c1.object_elem 
123 456
>>> print c2.static_elem, c2.object_elem
123 456

# Nothing new so far ...

# Let's try changing the static element
MyClass.static_elem = 999

>>> print c1.static_elem, c1.object_elem
999 456
>>> print c2.static_elem, c2.object_elem
999 456

# Now, let's try changing the object element
c1.object_elem = 888

>>> print c1.static_elem, c1.object_elem
999 888
>>> print c2.static_elem, c2.object_elem
999 456

As you can see, when we changed the class element, it changed for both objects. But, when we changed the object element, the other object remained unchanged.

You repository is bare, i.e. it does not have a working tree attached to it. You can clone it locally to create a working tree for it, or you could use one of several other options to tell Git where the working tree is, e.g. the --work-tree option for single commands, or the GIT_WORK_TREE environment variable. There is also the core.worktree configuration option but it will not work in a bare repository (check the man page for what it does).

# git --work-tree=/path/to/work/tree checkout master
# GIT_WORK_TREE=/path/to/work/tree git status

b has a capacity of 3, but a size of 0. The fact that ArrayList has some sort of buffer capacity is an implementation detail - it's not part of the List interface, so Collections.copy(List, List) doesn't use it. It would be ugly for it to special-case ArrayList.

As MrWiggles has indicated, using the ArrayList constructor which takes a collection is the way to in the example provided.

For more complicated scenarios (which may well include your real code), you may find the collections within Guava useful.

In addition to the excellent answers above, the following shows how to add text to each page of a multi-page document:

 using (var reader = new PdfReader(@"C:\Input.pdf"))
 {
    using (var fileStream = new FileStream(@"C:\Output.pdf", FileMode.Create, FileAccess.Write))
    {
       var document = new Document(reader.GetPageSizeWithRotation(1));
       var writer = PdfWriter.GetInstance(document, fileStream);

       document.Open();

       for (var i = 1; i <= reader.NumberOfPages; i++)
       {
          document.NewPage();

          var baseFont = BaseFont.CreateFont(BaseFont.HELVETICA_BOLD, BaseFont.CP1252, BaseFont.NOT_EMBEDDED);
          var importedPage = writer.GetImportedPage(reader, i);

          var contentByte = writer.DirectContent;
          contentByte.BeginText();
          contentByte.SetFontAndSize(baseFont, 12);

          var multiLineString = "Hello,\r\nWorld!".Split('\n');

          foreach (var line in multiLineString)
          {
             contentByte.ShowTextAligned(PdfContentByte.ALIGN_LEFT, line, 200, 200, 0);
          }

          contentByte.EndText();
          contentByte.AddTemplate(importedPage, 0, 0);
       }

       document.Close();
       writer.Close();
    }
 }

I was looking for a way to do this in the terminal and filter lines in the normal "grep behaviour". Have your strings in a file strings.txt:

string1
string2
...

Then you can build a regular expression like (string1|string2|...) and use it for filtering:

cmd1 | grep -P "($(cat strings.txt | tr '\n' '|' | head -c -1))" | cmd2

Edit: Above only works if you don't use any regex characters, if escaping is required, it could be done like:

cat strings.txt | python3 -c "import re, sys; [sys.stdout.write(re.escape(line[:-1]) + '\n') for line in sys.stdin]" | ...

In the SceneDelegate:

var window: UIWindow?

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options 
connectionOptions: UIScene.ConnectionOptions) {
    guard let windowScene = (scene as? UIWindowScene) else { return }
    window = UIWindow(windowScene: windowScene)
    let vc = UIViewController() //Instead of UIViewController() we initilise our initial viewController
    window?.rootViewController = vc
    window?.makeKeyAndVisible()
}

 <a href="http://twitter.com/me" class="twitterbird" title="Twitter link"></a>

use a class for the link itself and forget the div

.twitterbird {
 margin-bottom: 10px;
 width: 160px;
 height:160px;
 display:block;
 background:transparent url('twitterbird.png') center top no-repeat;
}

.twitterbird:hover {
   background-image: url('twitterbird_hover.png');

I hope this can help you!

Thank You.

You can do this for free with the following tools. You will need at least one real device (I used an iPhone 5)

Capture the video with the simple, but excellent appshow (note this is a very barebones tool, but it's very easy to learn). This will export at the native device resolution (640x1136).

Resize with ffmpeg. Due to rounding, you can go directly between the resolutions, but you have to oversize and then crop.

ffmpeg -i video.mov -filter:v scale=1084:1924 -c:a copy video_1084.mov
ffmpeg -i video_1084.mov -filter:v "crop=1080:1920:0:0" -c:a copy video_1080.mov

For ipad, you can crop and then add a letterbox. However, cropping like this usually won't yield a video that looks exactly like your app does on the ipad. YMMV.

ffmpeg -i video.mov -filter:v "crop=640:960:0:0" -c:a copy video_640_960.mo
ffmpeg -i video_640_960.mov -filter:v "pad=768:1024:64:32" -c:a copy video_768_1024.mov
ffmpeg -i video_768_1024.mov -filter:v scale=900:1200 -c:a copy video_900_1200.mov

This is a Python solution.

I have struggled with this for a long time, until I came across the cppreference.com explanation of the value categories.

It is actually rather simple, but I find that it is often explained in a way that's hard to memorize. Here it is explained very schematically. I'll quote some parts of the page:

Primary categories

The primary value categories correspond to two properties of expressions:

• has identity: it's possible to determine whether the expression refers to the same entity as another expression, such as by comparing addresses of the objects or the functions they identify (obtained directly or indirectly);

• can be moved from: move constructor, move assignment operator, or another function overload that implements move semantics can bind to the expression.

Expressions that:

• have identity and cannot be moved from are called lvalue expressions;
• have identity and can be moved from are called xvalue expressions;
• do not have identity and can be moved from are called prvalue expressions;
• do not have identity and cannot be moved from are not used.

lvalue

An lvalue ("left value") expression is an expression that has identity and cannot be moved from.

rvalue (until C++11), prvalue (since C++11)

A prvalue ("pure rvalue") expression is an expression that does not have identity and can be moved from.

xvalue

An xvalue ("expiring value") expression is an expression that has identity and can be moved from.

glvalue

A glvalue ("generalized lvalue") expression is an expression that is either an lvalue or an xvalue. It has identity. It may or may not be moved from.

rvalue (since C++11)

An rvalue ("right value") expression is an expression that is either a prvalue or an xvalue. It can be moved from. It may or may not have identity.

in controller just convert json data to object using json_decode php function like this

$member = json_decode($json_string); 

and pass to view in view

return view('page',compact('$member'))

in view blade

Member ID: {{$member->member[0]->id}}
Firstname: {{$member->member[0]->firstname}}
Lastname: {{$member->member[0]->lastname}}
Phone: {{$member->member[0]->phone}}

Owner ID: {{$member->owner[0]->id}}
Firstname: {{$member->owner[0]->firstname}}
Lastname: {{$member->owner[0]->lastname}}

Maybe you have run into this problem: net::ERR_INSECURE_RESPONSE

You need to check the encryption algorithms supported by your server. For example for apache you can configure the cipher suite this way: cipher suite.

Which version of chrome are you running and what is the server serving your APIs?

For the JSON library to be available, you may have to install libjson-ruby from your package manager.

To use the 'json' library:

require 'json'

To convert an object to JSON (these 3 ways are equivalent):

JSON.dump object #returns a JSON string
JSON.generate object #returns a JSON string
object.to_json #returns a JSON string

To convert JSON text to an object (these 2 ways are equivalent):

JSON.load string #returns an object
JSON.parse string #returns an object

It will be a bit more difficult for objects from your own classes. For the following class, to_json will produce something like "\"#<A:0xb76e5728>\"".

class A
    def initialize a=[1,2,3], b='hello'
        @a = a
        @b = b
    end
end

This probably isn't desirable. To effectively serialise your object as JSON, you should create your own to_json method. To go with this, a from_json class method would be useful. You could extend your class like so:

class A
    def to_json
        {'a' => @a, 'b' => @b}.to_json
    end
    def self.from_json string
        data = JSON.load string
        self.new data['a'], data['b']
    end
end

You could automate this by inheriting from a 'JSONable' class:

class JSONable
    def to_json
        hash = {}
        self.instance_variables.each do |var|
            hash[var] = self.instance_variable_get var
        end
        hash.to_json
    end
    def from_json! string
        JSON.load(string).each do |var, val|
            self.instance_variable_set var, val
        end
    end

Then you can use object.to_json to serialise to JSON and object.from_json! string to copy the saved state that was saved as the JSON string to the object.

When using JetBrains IDE's with Git, "stashing and unstashing actions are supported in addition to shelving and unshelving. These features have much in common; the major difference is in the way patches are generated and applied. Shelve can operate with either individual files or bunch of files, while Stash can only operate with a whole bunch of changed files at once. Here are some more details on the differences between them."

list comprehension formula:

[<value_when_condition_true> if <condition> else <value_when_condition_false> for value in list_name]

thus you can do it like this:

[y for y in a if y not in b]

Only for demonstration purpose : [y if y not in b else False for y in a ]

This worked for me (using Guzzle 6)

$client = new Client(); 
$result = $client->post('http://api.example.com', [
            'json' => [
                'value_1' => 'number1',
                'Value_group' =>  
                             array("value_2" => "number2",
                                    "value_3" => "number3")
                    ]
                ]);

echo($result->getBody()->getContents());

1.Create an xml circle_text_bg.xml in your res/drawable folder with the code below

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
     <solid android:color="#fff" />

    <stroke
        android:width="1dp"
        android:color="#98AFC7" />
    <corners
         android:bottomLeftRadius="50dp"
         android:bottomRightRadius="50dp"
         android:topLeftRadius="50dp"
         android:topRightRadius="50dp" />
    <size
         android:height="20dp"
         android:width="20dp" />
</shape>

2.Use circle_text_bg as the background for your textview. NB: In order to get a perfect circle your textview height and width should be the same.Preview of what your textview with text 1, 2, 3 with this background should look like this

I tried the solution by Çagatay Gürtürk but got the same weirdness as Luke the Obscure. Then tried the solution by Asa Kusuma. This works, but I believe it does the Ajax read every time the popover is displayed. The call to unbind('hover') has no effect. That's because delegate is monitoring for events in a specific class -- but that class is unchanged.

Here's my solution, closely based on Asa Kusuma's. Changes:

• Replaced delegate with on to match new JQuery libraries.
• Remove 'withajaxpopover' class rather than unbinding hover event (which was never bound)
• Add "trigger: hover" to the popover so that Bootstrap will handle it completely beginning with the second use.
• My data loading function returns JSon, which makes it easy to specify both the title and the content for the popover.

    /*  Goal: Display a tooltip/popover where the content is fetched from the
              application the first time only.

        How:  Fetch the appropriate content and register the tooltip/popover the first time 
              the mouse enters a DOM element with class "withajaxpopover".  Remove the 
              class from the element so we don't do that the next time the mouse enters.
              However, that doesn't show the tooltip/popover for the first time
              (because the mouse is already entered when the tooltip is registered).
              So we have to show/hide it ourselves.
    */
    $(function() {
      $('body').on('hover', '.withajaxpopover', function(event){
          if (event.type === 'mouseenter') {
              var el=$(this);
              $.get(el.attr('data-load'),function(d){
                  el.removeClass('withajaxpopover')
                  el.popover({trigger: 'hover', 
                              title: d.title, 
                              content: d.content}).popover('show');
              });
          }  else {
              $(this).popover('hide');
          }
      });
    });

Bracket notation can use variables, so it is useful in two instances where dot notation will not work:

1) When the property names are dynamically determined (when the exact names are not known until runtime).

2) When using a for..in loop to go through all the properties of an object.

There is also LibHaru

When it comes to Muhammad Mehdi's answer, it is better to do:

private void salary_texbox_PreviewTextInput(object sender, TextCompositionEventArgs e)
{
     Regex regex = new Regex ( "[^0-9]+" );
     if(regex.IsMatch(e.Text))
     {
         MessageBox.Show("Error");
     }
}

Because when comparing with the TextCompositionEventArgs it gets also the last character, while with the textbox.Text it does not. With textbox, the error will show after next inserted character.

You can't use Microsoft.Office.Interop.Excel without having ms office installed.

Just search in google for some libraries, which allows to modify xls or xlsx:

• http://code.google.com/p/excellibrary/
• http://simpleooxml.codeplex.com/ (only xlsx)

An answer with an important explanation:

There are two parameters of "TestNG" who are supposed to determine the order of execution the tests:

@Test(dependsOnGroups= "someGroup")

And:

@Test(dependsOnMethods= "someMethod")

In both cases these functions will depend on the method or group,

But the differences:

In this case:

@Test(dependsOnGroups= "someGroup")

The method will be dependent on the whole group, so it is not necessarily that immediately after the execution of the dependent function, this method will also be executed, but it may occur later in the run and even after other tests run.

It is important to note that in case and there is more than one use within the same set of tests in this parameter, this is a safe recipe for problems, because the dependent methods of the entire set of tests will run first and only then the methods that depend on them.

However, in this case:

@Test(dependsOnMethods= "someMethod")

Even if this parameter is used more than once within the same set of tests, the dependent method will still be executed after the dependent method is executed immediately.

Hope it's clearly and help.

Check you have:

1- Access to Internet connectivity.

2- The permission for internet is present in the manifest.

3- The url host is valid and registered in a trusted domain name server.

Update: Yes, I understand that this answer does not explain the difference between arm64 and armhf. There is a great answer that does explain that on this page. This answer was intended to help set the asker on the right path, as they clearly had a misunderstanding about the capabilities of the Raspberry Pi at the time of asking.

Where are you seeing that the architecture is armhf? On my Raspberry Pi 3, I get:

$ uname -a
armv7l

Anyway, armv7 indicates that the system architecture is 32-bit. The first ARM architecture offering 64-bit support is armv8. See this table for reference.

You are correct that the CPU in the Raspberry Pi 3 is 64-bit, but the Raspbian OS has not yet been updated for a 64-bit device. 32-bit software can run on a 64-bit system (but not vice versa). This is why you're not seeing the architecture reported as 64-bit.

You can follow the GitHub issue for 64-bit support here, if you're interested.

or

Object and Array in JavaScript are different in terms of usage. Its best if you understand them:

Object vs Array: JavaScript

You have to close that application first. There is no way to delete it, if it's used by some application.

UnLock IT is a neat utility that helps you to take control of any file or folder when it is locked by some application or system. For every locked resource, you get a list of locking processes and can unlock it by terminating those processes. EMCO Unlock IT offers Windows Explorer integration that allows unlocking files and folders by one click in the context menu.

There's also Unlocker (not recommended, see Warning below), which is a free tool which helps locate any file locking handles running, and give you the option to turn it off. Then you can go ahead and do anything you want with those files.

Warning: The installer includes a lot of undesirable stuff. You're almost certainly better off with UnLock IT.

Steve's reply is definitely the correct technique but it should be refactored so that your installpath variable is in a separate environment script where all such declarations are made.

Then all scripts source that script and should installpath change, you only need to change it in one location. Makes things more, er, futureproof. God I hate that word! (-:

BTW You should really refer to the variable using ${installpath} when using it in the way shown in your example:

. ${installpath}/incl.sh

If the braces are left out, some shells will try and expand the variable "installpath/incl.sh"!

len(myList) should do it.

len works with all the collections, and strings too.

on branchB do $git checkout branchA to switch to branch A

on branchA do $git merge branchB

That's all you need.

This is a bit old, but I guess what you want is: ps -o pid -C PROCESS_NAME, for example:

ps -o pid -C bash

EDIT: Dependening on the sort of output you expect, pgrep would be more elegant. This, in my knowledge, is Linux specific and result in similar output as above. For example:

pgrep bash

Select by description for jQuery v1.6+

jQuery versions below 1.6 and greater than or equal to 1.4

var text1 = 'Two';_x000D_
$("select option").filter(function() {_x000D_
  //may want to use $.trim in here_x000D_

UITableView has a property separatorInset. You can use that to set the insets of the table view separators to zero to let them span the full width of the screen.

[tableView setSeparatorInset:UIEdgeInsetsZero];

Note: If your app is also targeting other iOS versions, you should check for the availability of this property before calling it by doing something like this:

if ([tableView respondsToSelector:@selector(setSeparatorInset:)]) {
    [tableView setSeparatorInset:UIEdgeInsetsZero];
}

Below is an complete copy of the simplified script used in my other answer. Beyond additional error checking, there is an alias which allows the user to change the name of an existing alias. The syntax is given below. If the new_alias parameter is omitted, then the alias is removed.

POP UP WINDOWS IN APPLET

hi guys i was searching pop up windows in applet all over the internet but could not find answer for windows.

Although it is simple i am just helping you. Hope you will like it as it is in simpliest form. here's the code :

Filename: PopUpWindow.java for java file and we need html file too.

For applet let us take its popup.html

CODE:

import java.awt.*;

import java.applet.*;

import java.awt.event.*;

public class PopUpWindow extends Applet{

public void init(){

Button open = new Button("open window");

add(open);

Button close = new Button("close window");

add(close);

 Frame f = new Frame("pupup win");

  f.setSize(200,200);




 open.addActionListener(new ActionListener() {

                 public void actionPerformed(ActionEvent e) {
                     if(!f.isShowing()) {
                         f.setVisible(true);
                     }


                 }

              });
 close.addActionListener(new ActionListener() {

                 public void actionPerformed(ActionEvent e) {
                     if(f.isShowing()) {
                        f.setVisible(false);
                     }

                 }

              });

 }

}




/*
<html>

<body>

<APPLET CODE="PopUpWindow" width="" height="">

</APPLET>

</body>

</html>

*/


to run:
$javac PopUpWindow.java && appletviewer popup.html

Building upon the answers of the others, here is a one-liner solution that sets the tag date to when it actually happened, uses annotated tag and requires no git checkout:

tag="v0.1.3" commit="8f33a878" bash -c 'GIT_COMMITTER_DATE="$(git show --format=%aD $commit)" git tag -a $tag -m $tag $commit'
git push --tags origin master

where tag is set to the desired tag string, and commit to the commit hash.

The formula in C1

=IF(A1=1,B1,"")

is either giving an answer of "" (which isn't treated as blank) or the contents of B1.

If you want the formula in D1 to show TRUE if C1 is "" and FALSE if C1 has something else in then use the formula

=IF(C2="",TRUE,FALSE)

instead of ISBLANK

Now Its Updated and very easy to download!

Select your repository from Dashboard or Repository tab.

And then just click on Download tab having icon of download. It will Let you download whole repository in zip format.

You can try to force the soft keyboard to appear, it works for me:

...
dialog.show();
input.requestFocus();
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);

Guava also provides such function which will return an Optional if an enum cannot be found.

Enums.getIfPresent(MyEnum.class, id).toJavaUtil()
            .orElseThrow(()-> new RuntimeException("Invalid enum blah blah blah.....")))

You want to become familiar with parseInt() and toString().

And useful in your toolkit will be to look at a variable to find out what type it is—typeof:

<script type="text/javascript">
    /**
     * print out the value and the type of the variable passed in
     */

    function printWithType(val) {
        document.write('<pre>');
        document.write(val);
        document.write(' ');
        document.writeln(typeof val);
        document.write('</pre>');
    }

    var a = "1", b = "2", c = "3", result;

    // Step (1) Concatenate "1", "2", "3" into "123"
    // - concatenation operator is just "+", as long
    //   as all the items are strings, this works
    result = a + b + c;
    printWithType(result); //123 string

    // - If they were not strings you could do
    result = a.toString() + b.toString() + c.toString();
    printWithType(result); // 123 string

    // Step (2) Convert "123" into 123
    result = parseInt(result,10);
    printWithType(result); // 123 number

    // Step (3) Add 123 + 100 = 223
    result = result + 100;
    printWithType(result); // 223 number

    // Step (4) Convert 223 into "223"
    result = result.toString(); //
    printWithType(result); // 223 string

    // If you concatenate a number with a 
    // blank string, you get a string    
    result = result + "";
    printWithType(result); //223 string
</script>

Normally it is quite good to do:

echo isset($_GET['id']) ? $_GET['id'] : 'wtf';

This is so when assigning the var to other variables you can do defaults all in one breath instead of constantly using if statements to just give them a default value if they are not set.

Just for the reason of documentation:

I have now (2014) observed that from all these valuable and correct approaches only one was successful. I've added a function to the WSDL on the server, and the client wasn't recognizing the new function.

• Adding WSDL_CACHE_NONE to the parameters didn't help.
• Adding the cache-buster didn't help.
• Setting soap.wsdl_cache_enabled to the PHP ini helped.

I am now unsure if it is the combination of all three, or if some features are terribly implemented so they may remain useless randomly, or if there is some hierarchy of features not understood.

So finally, expect that you have to check all three to solve problems like these.

I know this is old question, I used to write my own VB.NET windows service, and it has no issue to start on MS windows 7 and MS windows 10.

I have this issue when I install the windows services on latest MS windows 10 patch. The reason the windows service doesn't run it is because the .NET version that needed for the window services to run is not presented in the installed PC.

After you have installed the windows services. go to the install folder for example C:\Program files (x86)\Service1\Service1.exe and double click to run it. If there is missing .NET framework package, it will prompt the user to download it. Just download and and wait for it to install.

After that restart the windows services in services.msc. Hope this answer will help someone who face the issue. I know issue is caused by .NET framework version.

For reference, a non-CSS solution:

Below is some JS that re-sizes a font depending on the text length within a container.

Codepen with slightly modified code, but same idea as below:

function scaleFontSize(element) {
    var container = document.getElementById(element);

    // Reset font-size to 100% to begin
    container.style.fontSize = "100%";

    // Check if the text is wider than its container,
    // if so then reduce font-size
    if (container.scrollWidth > container.clientWidth) {
        container.style.fontSize = "70%";
    }
}

For me, I call this function when a user makes a selection in a drop-down, and then a div in my menu gets populated (this is where I have dynamic text occurring).

    scaleFontSize("my_container_div");

In addition, I also use CSS ellipses ("...") to truncate yet even longer text too, like so:

#my_container_div {
    width: 200px; /* width required for text-overflow to work */
    white-space: nowrap;
    overflow: hidden;
    text-overflow: ellipsis;
}

So, ultimately:

• Short text: e.g. "APPLES"

  Fully rendered, nice big letters.

• Long text: e.g. "APPLES & ORANGES"

  Gets scaled down 70%, via the above JS scaling function.

• Super long text: e.g. "APPLES & ORANGES & BANAN..."

  Gets scaled down 70% AND gets truncated with a "..." ellipses, via the above JS scaling function together with the CSS rule.

You could also explore playing with CSS letter-spacing to make text narrower while keeping the same font size.

you can use the shell(bash for example)

$ string="12 BBQ ,45 rofl, 89 lol"
$ echo ${string% rofl*}
12 BBQ ,45
$ string=${string% rofl*}
$ echo ${string##*,}
45

I like the Infragistics controls. The WebDropDown has what you need. The only drawback is they can be a bit spendy.

Use the object syntax.

v-bind:class="{'fa-checkbox-marked': content['cravings'],  'fa-checkbox-blank-outline': !content['cravings']}"

When the object gets more complicated, extract it into a method.

v-bind:class="getClass()"

methods:{
    getClass(){
        return {
            'fa-checkbox-marked': this.content['cravings'],  
            'fa-checkbox-blank-outline': !this.content['cravings']}
    }
}

Finally, you could make this work for any content property like this.

v-bind:class="getClass('cravings')"

methods:{
  getClass(property){
    return {
      'fa-checkbox-marked': this.content[property],
      'fa-checkbox-blank-outline': !this.content[property]
    }
  }
}

for a in someList:
    list.append(splitColon.split(a))

You can rewrite the above as:

newlist = [splitColon.split(a) for a in someList]

If I understand what you need, try this:

SELECT id, pass, AVG(val) AS val_1 
FROM data_r1 
GROUP BY id, pass;

Or, if you want just one row for every id, this:

SELECT d1.id,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 1) as val_1,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 2) as val_2,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 3) as val_3,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 4) as val_4,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 5) as val_5,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 6) as val_6,
    (SELECT IFNULL(ROUND(AVG(d2.val), 4) ,0) FROM data_r1 d2 
     WHERE d2.id = d1.id AND pass = 7) as val_7
from data_r1 d1
GROUP BY d1.id

1. Installing OpenCV 2.4.3

First, get OpenCV 2.4.3 from sourceforge.net. Its a self-extracting so just double click to start the installation. Install it in a directory, say C:\.

Wait until all files get extracted. It will create a new directory C:\opencv which contains OpenCV header files, libraries, code samples, etc.

Now you need to add the directory C:\opencv\build\x86\vc10\bin to your system PATH. This directory contains OpenCV DLLs required for running your code.

Open Control Panel → System → Advanced system settings → Advanced Tab → Environment variables...

On the System Variables section, select Path (1), Edit (2), and type C:\opencv\build\x86\vc10\bin; (3), then click Ok.

On some computers, you may need to restart your computer for the system to recognize the environment path variables.

This will completes the OpenCV 2.4.3 installation on your computer.

2. Create a new project and set up Visual C++

Open Visual C++ and select File → New → Project... → Visual C++ → Empty Project. Give a name for your project (e.g: cvtest) and set the project location (e.g: c:\projects).

Click Ok. Visual C++ will create an empty project.

Make sure that "Debug" is selected in the solution configuration combobox. Right-click cvtest and select Properties → VC++ Directories.

Select Include Directories to add a new entry and type C:\opencv\build\include.

Click Ok to close the dialog.

Back to the Property dialog, select Library Directories to add a new entry and type C:\opencv\build\x86\vc10\lib.

Click Ok to close the dialog.

Back to the property dialog, select Linker → Input → Additional Dependencies to add new entries. On the popup dialog, type the files below:

opencv_calib3d243d.lib
opencv_contrib243d.lib
opencv_core243d.lib
opencv_features2d243d.lib
opencv_flann243d.lib
opencv_gpu243d.lib
opencv_haartraining_engined.lib
opencv_highgui243d.lib
opencv_imgproc243d.lib
opencv_legacy243d.lib
opencv_ml243d.lib
opencv_nonfree243d.lib
opencv_objdetect243d.lib
opencv_photo243d.lib
opencv_stitching243d.lib
opencv_ts243d.lib
opencv_video243d.lib
opencv_videostab243d.lib

Note that the filenames end with "d" (for "debug"). Also note that if you have installed another version of OpenCV (say 2.4.9) these filenames will end with 249d instead of 243d (opencv_core249d.lib..etc).

Click Ok to close the dialog. Click Ok on the project properties dialog to save all settings.

NOTE:

These steps will configure Visual C++ for the "Debug" solution. For "Release" solution (optional), you need to repeat adding the OpenCV directories and in Additional Dependencies section, use:

opencv_core243.lib
opencv_imgproc243.lib
...

instead of:

opencv_core243d.lib
opencv_imgproc243d.lib
...

You've done setting up Visual C++, now is the time to write the real code. Right click your project and select Add → New Item... → Visual C++ → C++ File.

Name your file (e.g: loadimg.cpp) and click Ok. Type the code below in the editor:

#include <opencv2/highgui/highgui.hpp>
#include <iostream>

using namespace cv;
using namespace std;

int main()
{
    Mat im = imread("c:/full/path/to/lena.jpg");
    if (im.empty()) 
    {
        cout << "Cannot load image!" << endl;
        return -1;
    }
    imshow("Image", im);
    waitKey(0);

The code above will load c:\full\path\to\lena.jpg and display the image. You can use any image you like, just make sure the path to the image is correct.

Type F5 to compile the code, and it will display the image in a nice window.

And that is your first OpenCV program!

3. Where to go from here?

Now that your OpenCV environment is ready, what's next?

1. Go to the samples dir → c:\opencv\samples\cpp.
2. Read and compile some code.
3. Write your own code.

Bootstrap 5 has changed the ml,mr,pl,pr classes, which no longer work if you're upgrading from a lower version. The l and r have now been replaced with s(...which is confusing) and e(east?) respectively.

From bootstrap website:

Where property is one of:

• m - for classes that set margin
• p - for classes that set padding

Where sides is one of:

• t - for classes that set margin-top or padding-top
• b - for classes that set margin-bottom or padding-bottom
• s - for classes that set margin-left or padding-left in LTR, margin-right or padding-right in RTL
• e - for classes that set margin-right or padding-right in LTR, margin-left or padding-left in RTL
• x - for classes that set both *-left and *-right
• y - for classes that set both *-top and *-bottom blank - for classes that set a margin or padding on all 4 sides of the element Where size is one of:

0 - for classes that eliminate the margin or padding by setting it to 0 1 - (by default) for classes that set the margin or padding to $spacer * .25 2 - (by default) for classes that set the margin or padding to $spacer * .5 3 - (by default) for classes that set the margin or padding to $spacer 4 - (by default) for classes that set the margin or padding to $spacer * 1.5 5 - (by default) for classes that set the margin or padding to $spacer * 3 auto - for classes that set the margin to auto (You can add more sizes by adding entries to the $spacers Sass map variable.)

A nice code for the push_back and emplace_back is shown here.

You can see the move operation on push_back and not on emplace_back.

Let us consider a table which stores the shift details

Please check the SQL queries to generate table and finding the schedule based on an input(time)

Declaring the Table variable

declare @MyShiftTable table(MyShift int,StartTime time,EndTime time)

Adding values to Table variable

insert into @MyShiftTable select 1,'01:17:40.3530000','02:17:40.3530000'
insert into @MyShiftTable select 2,'09:17:40.3530000','03:17:40.3530000'
insert into @MyShiftTable select 3,'10:17:40.3530000','18:17:40.3530000'

Creating another table variable with an additional field named "Flag"

declare @Temp table(MyShift int,StartTime time,EndTime time,Flag int)

Adding values to temporary table with swapping the start and end time

insert into @Temp select MyShift,case when (StartTime>EndTime) then EndTime else StartTime end,case when (StartTime>EndTime) then StartTime else EndTime end,case when (StartTime>EndTime) then 1 else 0 end from @MyShiftTable

Creating input variable to find the Shift

declare @time time=convert(time,'10:12:40.3530000')

Query to find the shift corresponding to the time supplied

select myShift from @Temp where
(@time between StartTime and EndTime and Flag=0) or (@time not between StartTime and EndTime and Flag=1)

Others have answered "how" and quoted spec. Here is the real story of "why no <script/>", after many hours digging into bug reports and mailing lists.

HTML 4

HTML 4 is based on SGML.

SGML has some shorttags, such as <BR//, <B>text</>, <B/text/, or <OL<LI>item</LI</OL>. XML takes the first form, redefines the ending as ">" (SGML is flexible), so that it becomes <BR/>.

However, HTML did not redfine, so <SCRIPT/> should mean <SCRIPT>>.
(Yes, the '>' should be part of content, and the tag is still not closed.)

Obviously, this is incompatible with XHTML and will break many sites (by the time browsers were mature enough to care about this), so nobody implemented shorttags and the specification advises against them.

Effectively, all 'working' self-ended tags are tags with prohibited end tag on technically non-conformant parsers and are in fact invalid. It was W3C which came up with this hack to help transitioning to XHTML by making it HTML-compatible.

And <script>'s end tag is not prohibited.

"Self-ending" tag is a hack in HTML 4 and is meaningless.

HTML 5

HTML5 has five types of tags and only 'void' and 'foreign' tags are allowed to be self-closing.

Because <script> is not void (it may have content) and is not foreign (like MathML or SVG), <script> cannot be self-closed, regardless of how you use it.

But why? Can't they regard it as foreign, make special case, or something?

HTML 5 aims to be backward-compatible with implementations of HTML 4 and XHTML 1. It is not based on SGML or XML; its syntax is mainly concerned with documenting and uniting the implementations. (This is why <br/> <hr/> etc. are valid HTML 5 despite being invalid HTML4.)

Self-closing <script> is one of the tags where implementations used to differ. It used to work in Chrome, Safari, and Opera; to my knowledge it never worked in Internet Explorer or Firefox.

This was discussed when HTML 5 was being drafted and got rejected because it breaks browser compatibility. Webpages that self-close script tag may not render correctly (if at all) in old browsers. There were other proposals, but they can't solve the compatibility problem either.

After the draft was released, WebKit updated the parser to be in conformance.

Self-closing <script> does not happen in HTML 5 because of backward compatibility to HTML 4 and XHTML 1.

XHTML 1 / XHTML 5

When really served as XHTML, <script/> is really closed, as other answers have stated.

Except that the spec says it should have worked when served as HTML:

XHTML Documents ... may be labeled with the Internet Media Type "text/html" [RFC2854], as they are compatible with most HTML browsers.

So, what happened?

People asked Mozilla to let Firefox parse conforming documents as XHTML regardless of the specified content header (known as content sniffing). This would have allowed self-closing scripts, and content sniffing was necessary anyway because web hosters were not mature enough to serve the correct header; IE was good at it.

If the first browser war didn't end with IE 6, XHTML may have been on the list, too. But it did end. And IE 6 has a problem with XHTML. In fact IE did not support the correct MIME type at all, forcing everyone to use text/html for XHTML because IE held major market share for a whole decade.

And also content sniffing can be really bad and people are saying it should be stopped.

Finally, it turns out that the W3C didn't mean XHTML to be sniffable: the document is both, HTML and XHTML, and Content-Type rules. One can say they were standing firm on "just follow our spec" and ignoring what was practical. A mistake that continued into later XHTML versions.

Anyway, this decision settled the matter for Firefox. It was 7 years before Chrome was born; there were no other significant browser. Thus it was decided.

Specifying the doctype alone does not trigger XML parsing because of following specifications.

To add a stacktrace click on the Gradle on the right side of Android project screen;

1. Click on the settings icon; this will open the settings page,

2. Then click on compiler

3. Then add the command --stacktrace or --debug as shown;

   

4. Run the application again to get the gradle report.

This one worked, double quotes when $user and $password are outside single quotes. Single quotes when inside a single quote statement.

Running IIS 7.5, I had luck adding permissions for the local computer user IUSR. The app pool user didn't work.

This will delete the duplicate rows with same values for title, company and site. The first occurrence will be kept and rest all duplicates will be deleted

DELETE t1 FROM tablename t1
INNER JOIN tablename t2 
WHERE

    t1.title = t2.title AND
    t1.company=t2.company AND
    t1.site_ID=t2.site_ID;

The easiest and the simplest way to check system version (and a lot of other versions) in Swift 2 and higher is:

if #available(iOS 9.0, *) { // check for iOS 9.0 and later

}

Also, with #available you can check versions of these:

iOS
iOSApplicationExtension
macOS
macOSApplicationExtension
watchOS
watchOSApplicationExtension
tvOS
tvOSApplicationExtension
swift

Just to complete this with the most stupid method I can come up with: Generate all possible strings of length 1, use equals to compare them to the original string; if they are equal, the string length is 1. If no string matches, generate all possible strings of length 2, compare them, for string length 2. Etc. Continue until you find the string length or the universe ends, whatever happens first.

    EditText ET1 = (EditText) findViewById(R.id.editText1);

    PackageInfo pinfo;
    try {
        pinfo = getPackageManager().getPackageInfo(getPackageName(), 0);
        String versionName = pinfo.versionName;
        ET1.setText(versionName);
        //ET2.setText(versionNumber);
    } catch (NameNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

Assign variable to the blade template, Here are the solutions

We can use <?php ?> tag in blade page

<?php $var = 'test'; ?>
{{ $var }

OR

We can use the blade comment with special syntax

{{--*/ $var = 'test' /*--}}
{{ $var }}

Omit the double quotes from your first query.

... LIKE '%\n%' 

We had the same issue and, in our case, it was resolved by reinstalling the certificate and creating the binding again. What lead us there was the fact that even getting a simple png image file on the site give the same error.

You could try the following

select case when mydatetime IS NULL THEN '' else convert(varchar(20),@mydatetime,120) end as converted_date from sometable

-- Testing it out could do --

declare @mydatetime datetime
set @mydatetime = GETDATE() -- comment out for null value
--set @mydatetime = GETDATE()

select 
case when @mydatetime IS NULL THEN ''
else convert(varchar(20),@mydatetime,120)
end as converted_date

Hope this helps!

If you don't mind using 3rd Party Libraries cyclops-react has an extended Stream type that will allow you to do just that via the append / prepend operators.

Individual values, arrays, iterables, Streams or reactive-streams Publishers can be appended and prepended as instance methods.

Stream stream = ReactiveSeq.of(1,2)
                           .filter(x -> x!=0)
                           .append(ReactiveSeq.of(3,4))
                           .filter(x -> x!=1)
                           .append(5)
                           .filter(x -> x!=2);

 request.headers.add("body", json.encode(map));

I attached the encoded json body data to the header and added to it. It works for me.

For those using NHibernate, this is a port of [ram]'s code

public static string GenerateSQL(ICriteria criteria)
    {
        NHibernate.Impl.CriteriaImpl criteriaImpl = (NHibernate.Impl.CriteriaImpl)criteria;
        NHibernate.Engine.ISessionImplementor session = criteriaImpl.Session;
        NHibernate.Engine.ISessionFactoryImplementor factory = session.Factory;

        NHibernate.Loader.Criteria.CriteriaQueryTranslator translator = 
            new NHibernate.Loader.Criteria.CriteriaQueryTranslator(
                factory, 
                criteriaImpl, 
                criteriaImpl.EntityOrClassName, 
                NHibernate.Loader.Criteria.CriteriaQueryTranslator.RootSqlAlias);

        String[] implementors = factory.GetImplementors(criteriaImpl.EntityOrClassName);

        NHibernate.Loader.Criteria.CriteriaJoinWalker walker = new NHibernate.Loader.Criteria.CriteriaJoinWalker(
            (NHibernate.Persister.Entity.IOuterJoinLoadable)factory.GetEntityPersister(implementors[0]),
                                translator,
                                factory,
                                criteriaImpl,
                                criteriaImpl.EntityOrClassName,
                                session.EnabledFilters);

        return walker.SqlString.ToString();
    }

The bottom statement is equivalent to:

.half {
   flex-grow: 0;
   flex-shrink: 0;
   flex-basis: 50%;
}

Which, in this case, would be equivalent as the box is not allowed to flex and therefore retains the initial width set by flex-basis.

Flex-basis defines the default size of an element before the remaining space is distributed so if the element were allowed to flex (grow/shrink) it may not be 50% of the width of the page.

I've found that I regularly return to https://css-tricks.com/snippets/css/a-guide-to-flexbox/ for help regarding flexbox :)

Add a class:

.com_box:after {
     content: '';
    position: absolute;
    left: 18px;
    top: 50px;
    width: 0;
    height: 0;
    border-left: 20px solid transparent;
    border-right: 20px solid transparent;
    border-top: 20px solid #000;
    clear: both;

}

Use FOR XML PATH('') - which is converting the entries to a comma separated string and STUFF() -which is to trim the first comma- as follows Which gives you the same comma separated result

SELECT  STUFF((SELECT  ',' + INSTITUTIONNAME
            FROM EDUCATION EE
            WHERE  EE.STUDENTNUMBER=E.STUDENTNUMBER
            ORDER BY sortOrder
        FOR XML PATH('')), 1, 1, '') AS listStr

FROM EDUCATION E
GROUP BY E.STUDENTNUMBER

Here is the FIDDLE

Java, unlike languages like C and C++, treats boolean as a completely separate data type which has 2 distinct values: true and false. The values 1 and 0 are of type int and are not implicitly convertible to boolean.

Array functional way:

   array.enumerated().filter { $0.offset < limit }.map { $0.element }

ranged:

 array.enumerated().filter { $0.offset >= minLimit && $0.offset < maxLimit }.map { $0.element }

The advantage of this method is such implementation is safe.

I think this happen because the name of your class is the same name of another class in the JDK . Help eclipse to determine which one you are trying to run by selecting the package your class is in . Go to run configuration select the project and the main class.

When you press the search button to select the main class, you will find options that have the same name but different package, select your class.

both your conditions are the same:

if(s < f) {     calc = f - s;     n = s; }else if(f > s){     calc =  s - f;     n = f;  } 

so

if(s < f)   

and

}else if(f > s){ 

are the same

change to

}else if(f < s){ 

return value.replaceAll("[^A-Za-z0-9 ]", "");

This will leave spaces intact. I assume that's what you want. Otherwise, remove the space from the regex.

You can use the eclipse plugin as suggested by Oscar earlier. Or if you are a command line person, you can use Apache Axis WSDL2Java tool from command prompt. You can find more details here http://axis.apache.org/axis/java/reference.html#WSDL2JavaReference

I think this should be what you want:

System.Reflection.Assembly.GetEntryAssembly().Location

This returns the assembly that was first loaded when the process started up, which would seem to be what you want.

GetCallingAssembly won't necessarily return the assembly you want in the general case, since it returns the assembly containing the method immediately higher in the call stack (i.e. it could be in the same DLL).

Shockingly, the syntax has changed yet again in the latest version of Angular :-) From the Angular 6 docs:

Beginning with Angular 6.0, the preferred way to create a singleton services is to specify on the service that it should be provided in the application root. This is done by setting providedIn to root on the service's @Injectable decorator:

src/app/user.service.0.ts

import { Injectable } from '@angular/core';

@Injectable({
  providedIn: 'root',
})
export class UserService {
}

When nesting repetition operators, make absolutely sure that there is only one way to match the same match.

I just wanted to know if the dictionary i was going to try to pull data from had data in it in the first place, this seems to be simplest way.

d = {}

bool(d)

#should return
False

d = {'hello':'world'}

bool(d)

#should return
True

The solution, if your list items can be display: inline is quite easy:

#footer { text-align: center; }
#footer ul { list-style: none; }
#footer ul li { display: inline; }

However, many times you must use display:block on your <li>s. The following CSS will work, in this case:

#footer { width: 100%; overflow: hidden; }
#footer ul { list-style: none; position: relative; float: left; display: block; left: 50%; }
#footer ul li { position: relative; float: left; display: block; right: 50%; }

If you must, this is how you can do it in a for loop:

mylist = ['first', 'second', 'other']
endstring = ''
for s in mylist:
  endstring += s

but you should consider using join():

''.join(mylist)

the first parameters of function JSON.parse should be a String, and your data is a JavaScript object, so it will convert to a String [object object], you should use JSON.stringify before pass the data

JSON.parse(JSON.stringify(userData))

As you are using SQL Server 2008, go with Martin's answer.

To complement Felix Kling's answer, I was studying a codebase that used to have the following code:

if (is_array($start_vars)) {
    foreach ($start_vars as $var) {
        session_register($var);
    }
} else if (!(empty($start_vars))) {
    session_register($start_vars);
}

In order to not use session_register they made the following adjustments:

if (is_array($start_vars)) {
    foreach ($start_vars as $var) {
        $_SESSION[$var] =  $GLOBALS[$var];
    }
} else if (!(empty($start_vars))) {
    $_SESSION[$start_vars] =  $GLOBALS[$start_vars];
}

In findFileByFilename.ps1 I have:

gci . -recurse -filter $filename -file -ErrorAction SilentlyContinue
# tested works from pwd recursively.

This works great for me. I understand it.

I put it in a folder on my PATH.

I invoke it with:

A .war file has a specific structure in terms of where certain files will be. Other than that, yes, it's just a .jar.

If you want your form's field clear, you must only add a delay in the onClick event like:

<input name="submit" id="MyButton" type="submit" class="btn-lg" value="ClickMe" onClick="setTimeout('clearform()', 2000 );"

onClick="setTimeout('clearform()', 1500 );" . in 1,5 seconds its clear

document.getElementById("name").value = "";  <<<<<<just correct this
document.getElementById("telephone").value = "";    <<<<<correct this

By clearform(), I mean your clearing-fields function.

If you want to completely destroy the target, you have a couple of options. First you can remove the object from the DOM as described above...

console.log($target);   // jQuery object
$target.remove();       // remove target from the DOM
console.log($target);   // $target still exists

Option 1 - Then replace target with an empty jQuery object (jQuery 1.4+)

$target = $();
console.log($target);   // empty jQuery object

Option 2 - Or delete the property entirely (will cause an error if you reference it elsewhere)

delete $target;
console.log($target);   // error: $target is not defined

Since we are doing this one to death - you don't have to specify a year:

select * from demo
where  somedate between to_date('01/01 00:00:00', 'DD/MM HH24:MI:SS')
                and     to_date('31/12 23:59:59', 'DD/MM HH24:MI:SS');

However the accepted answer by FerranB makes more sense if you want to specify all date values that fall within the current year.

I use a simple case statement to render results I can use in technical specification documents. This example does not contain every condition you will run into with a database, but it gives you a good template to work with.

     COLUMN_NAME         AS 'Column Name',
     CASE WHEN DATA_TYPE LIKE '%char'
          THEN DATA_TYPE + '(' + CONVERT(VARCHAR, CHARACTER_MAXIMUM_LENGTH) + ')'
          WHEN DATA_TYPE IN ('bit', 'int', 'smallint', 'date')
          THEN DATA_TYPE

print map { "$_ $h{$_}\n" } keys %h;

or

print "$_ $h{$_}\n" for keys %h;

will do, but if you have a hash that is populated with references you will something that can walk those references and produce a sensible output. This walking of the references is normally called serialization. There are many modules that implement different styles, some of the more popular ones are:

• Data::Dumper
• Data::Dump::Streamer
• YAML::XS
• JSON::XS
• XML::Dumper

Due to the fact that Data::Dumper is part of the core Perl library, it is probably the most popular; however, some of the other modules have very good things to offer.

Use: cast(date_parse(inv.date_created,'%Y-%m-%d %h24:%i:%s') as date)

Input: String timestamp

Output: date format 'yyyy-mm-dd'

step 1 : make a web service on your server

step 2 : make your application make a call to the web service and receive result sets

Lets define the dataframe from your example by

>>> df = pd.DataFrame([[206, 214], [226, 234], [245, 253], [265, 272], [283, 291]], 
    columns=[1, 2])
>>> df
     1    2
0  206  214
1  226  234
2  245  253
3  265  272
4  283  291

Then you could manipulate the index of the second column by

>>> df[2].index = df[2].index+1

and finally re-combine the single columns

>>> pd.concat([df[1], df[2]], axis=1)
       1      2
0  206.0    NaN
1  226.0  214.0
2  245.0  234.0
3  265.0  253.0
4  283.0  272.0
5    NaN  291.0

Perhaps not fast but simple to read. Consider setting variables for the column names and the actual shift required.

Edit: Generally shifting is possible by df[2].shift(1) as already posted however would that cut-off the carryover.

Just for the sake of it, there is of course the possibility to create Void instance using reflection:

interface B<E>{ E method(); }

class A implements B<Void>{

    public Void method(){
        // do something

        try {
            Constructor<Void> voidConstructor = Void.class.getDeclaredConstructor();
            voidConstructor.setAccessible(true);
            return voidConstructor.newInstance();
        } catch (Exception ex) {
            // Rethrow, or return null, or whatever.
        }
    }
}

You probably won't do that in production.

Short answer is no.

XAMPP is normally built around a specific PHP version to ensure plugins and modules are all compatible and working correctly.

If your project specifically needs PHP 5.3 - the cleanest method is simply reinstalling an older version of XAMPP with PHP 5.3 packaged into it.

XAMPP 1.7.7 was their last update before moving off PHP 5.3.

In my case I was using a JDK 8 client and the server was using insecure old ciphers. The server is Apache and I added this line to the Apache config:

SSLCipherSuite ALL:!ADH:RC4+RSA:+HIGH:!MEDIUM:!LOW:!SSLv2:!EXPORT

You should use a tool like this to verify your SSL configuration is currently secure: https://www.ssllabs.com/ssltest/analyze.html

The above works,(having an original document with mixed pages of 11' and 16' wide). However auto rotate needs to be off otherwise landscape pages are saved with page white top and bottom, so dont work in full screen view.

Solution is to re open the new PDF in acrobat and crop the first image (carefully to avoid white border), then select page range i.e. all, this then applies to all pages. job done !

Four (more) Reliable Options.

An unquoted asterisk * will be interpreted as a pattern (glob) by the shell. The shell will use it in pathname expansion. It will then generate a list of filenames that match the pattern.

A simple asterisk will match all filenames in the PWD (present working directory). A more complex pattern as */ will match all filenames that end in /. Thus, all directories. That is why the command:

1.- echo.

echo */
echo ./*/              ### Avoid misinterpreting filenames like "-e dir"

will be expanded (by the shell) to echo all directories in the PWD.

To test this: Create a directory (mkdir) named like test-dir, and cd into it:

mkdir test-dir; cd test-dir

Create some directories:

mkdir {cs,files,masters,draft,static}   # Safe directories.
mkdir {*,-,--,-v\ var,-h,-n,dir\ with\ spaces}  # Some a bit less secure.
touch -- 'file with spaces' '-a' '-l' 'filename'    # And some files:

The command echo ./*/ will remain reliable even with odd named files:

./--/ ./-/ ./*/ ./cs/ ./dir with spaces/ ./draft/ ./files/ ./-h/
./masters/ ./-n/ ./static/ ./-v var/

But the spaces in filenames make reading a bit confusing.

If instead of echo, we use ls. The shell is still what is expanding the list of filenames. The shell is the reason to get a list of directories in the PWD. The -d option to ls makes it list the present directory entry instead of the contents of each directory (as presented by default).

ls -d */

However, this command is (somewhat) less reliable. It will fail with the odd named files listed above. It will choke with several names. You need to erase one by one till you find the ones with problems.

2.- ls

The GNU ls will accept the "end of options" (--) key.

ls -d ./*/                     ### More reliable BSD ls
ls -d -- */                    ### More reliable GNU ls

3.-printf

To list each directory in its own line (in one column, similar to ls -1), use:

$ printf "%s\n" */        ### Correct even with "-", spaces or newlines.

And, even better, we could remove the trailing /:

$ set -- */; printf "%s\n" "${@%/}"        ### Correct with spaces and newlines.

An attempt like

$ for i in $(ls -d */); do echo ${i%%/}; done

will fail on:

• some names (ls -d */) as already shown above.
• will be affected by the value of IFS.
• will split names on spaces and tabs (with default IFS).
• each newline in the name will start a new echo command.

4.- Function

Finally, using the argument list inside a function will not affect the arguments list of the present running shell. Simply

$ listdirs(){ set -- */; printf "%s\n" "${@%/}"; }
$ listdirs

presents this list:

--
-
*
cs
dir with spaces
draft
files
-h
masters
-n
static
-v var

These options are safe with several types of odd filenames.

The best thing to do is to create a "print-only" version of the page.

Oh, wait... this isn't 1999 anymore. Use a print CSS with "display: none".

I tried this and it worked :

git stash && git add . && git stash pop

git stash will only put all modified tracked files into separate stack, then left over files are untracked files. Then by doing git add . will stage all files untracked files, as required. Eventually, to get back all modified files from stack by doing git stash pop

We use a CTE wrapped in Dynamic SQL (because our application requires dynamic sorting of data server side) within a stored procedure. I can provide a basic example if you'd like.

I haven't had a chance to look at the T/SQL that LINQ produces. Can someone post a sample?

We don't use LINQ or straight access to the tables as we require the extra layer of security (granted the dynamic SQL breaks this somewhat).

Something like this should do the trick. You can add in parameterized values for parameters, etc.

exec sp_executesql 'WITH MyCTE AS (
    SELECT TOP (10) ROW_NUMBER () OVER ' + @SortingColumn + ' as RowID, Col1, Col2
    FROM MyTable
    WHERE Col4 = ''Something''
)
SELECT *
FROM MyCTE
WHERE RowID BETWEEN 10 and 20'

If you add the following attribute to your activity's manifest definition, it will completely suppress the keyboard from popping when your activity opens. Hopefully this helps:

(Add to your Activity's manifest definition):

android:windowSoftInputMode="stateHidden"

This here will make the column column_name into a primary key, and in the meantime ignore all errors. So it will delete the rows with a duplicate value for column_name.

ALTER IGNORE TABLE `table_name` ADD PRIMARY KEY (`column_name`);

Like stated in this question: Git: Create a branch from unstagged/uncommited changes on master: stash is not necessary.

Just use:

git checkout -b topic/newbranch

Any uncommitted work will be taken along to the new branch.

If you try to push you will get the following message

fatal: The current branch feature/NEWBRANCH has no upstream branch. To push the current branch and set the remote as upstream, use

git push --set-upstream origin feature/feature/NEWBRANCH

Just do as suggested to create the branch remotely:

git push --set-upstream origin feature/feature/NEWBRANCH

It seems that your eclipse-workspace (or at least your Project) is broken somehow.

Have you moved your android-sdk/Project recently? If it's not an Android Project anymore, try to look at Preferences->Android for a valid android sdk-location.

If this is correct, try to open a complete new Workspace, and import your sources with File->import->Android Project from existing Source.

If this still doesn't help, make a new android Project and copy the sources manually inside your Project from outside Eclipse. Re-open Eclipse after that, and make a Project->clean

Use perl -i, with a command that replaces the beginning of line 1 with what you want to insert (the .bk will have the effect that your original file is backed up):

perl -i.bk -pe 's/^/column1, column2, column3\n/ if($.==1)' testfile.csv  

depending on the cryptography algorithm you are using, you may have to add some padding bytes at the end before encrypting a byte array so that the length of the byte array is multiple of the block size:

Specifically in your case the padding schema you chose is PKCS5 which is described here: http://www.rsa.com/products/bsafe/documentation/cryptoj35html/doc/dev_guide/group_CJ_SYM__PAD.html

(I assume you have the issue when you try to encrypt)

You can choose your padding schema when you instantiate the Cipher object. Supported values depend on the security provider you are using.

By the way are you sure you want to use a symmetric encryption mechanism to encrypt passwords? Wouldn't be a one way hash better? If you really need to be able to decrypt passwords, DES is quite a weak solution, you may be interested in using something stronger like AES if you need to stay with a symmetric algorithm.

You don't need to test if $? is not 0. The shell provides && and || so you can easily branch based on implicit result of that test:

some_command && {
    # executes this block of code,
    # if some_command would result in:  $? -eq 0
} || {
    # executes this block of code,
    # if some_command would result in:  $? -ne 0
}

You can remove either branch, depending on what you want. So if you just want to test for failure (i.e. $? -ne 0):

some_command_returning_nonzero || {
    # executes this block of code when:     $? -ne 0
    # and nothing if the command succeeds:  $? -eq 0
}

However, the code you provided in the question works, as is. I'm confused that you got syntax errors & concluded that $? was a string. It's most likely that the errant code causing the syntax error was not provided with the question. This is especially evident because you claim that no one else's solutions work either. When this happens, you have to re-evaluate your assumptions.

NB: The code above may give confusing results if the code inside the braces returns an error. In that case simply use the if command instead, like this:

if some_command; then
    # executes this block of code,
    # if some_command would result in:  $? -eq 0
else
    # executes this block of code,
    # if some_command would result in:  $? -ne 0
fi

Another way to change the color is remove the default class and replace , in the panel using the classes of bootstrap.

example:

<div class="panel panel-danger">
  <div class="panel-heading">
  </div>
</div>

Probably for the same reason that there is no tree container in boost. There are many ways to implement such a container, and there is no good way to satisfy everyone who would use it.

Some issues to consider:

• Are the number of children for a node fixed or variable?
• How much overhead per node? - ie, do you need parent pointers, sibling pointers, etc.
• What algorithms to provide? - different iterators, search algorithms, etc.

In the end, the problem ends up being that a tree container that would be useful enough to everyone, would be too heavyweight to satisfy most of the people using it. If you are looking for something powerful, Boost Graph Library is essentially a superset of what a tree library could be used for.

Here are some other generic tree implementations:

• Kasper Peeters' tree.hh
• Adobe's forest
• core::tree

I suggest using the Google Charts API because you can specify the text, text color, fill color and outline color, all using hex color codes, e.g. #FF0000 for red. You can call it as follows:

function getIcon(text, fillColor, textColor, outlineColor) {
  if (!text) text = '•'; //generic map dot
  var iconUrl = "http://chart.googleapis.com/chart?cht=d&chdp=mapsapi&chl=pin%27i\\%27[" + text + "%27-2%27f\\hv%27a\\]h\\]o\\" + fillColor + "%27fC\\" + textColor + "%27tC\\" + outlineColor + "%27eC\\Lauto%27f\\&ext=.png";
  return iconUrl;
}

Then, when you create your marker you just set the icon property as such, where the myColor variables are hex values (minus the hash sign):

var marker = new google.maps.Marker({
  position: new google.maps.LatLng(locations[i][1], locations[i][2]),
  animation: google.maps.Animation.DROP,
  map: map,
  icon: getIcon(null, myColor, myColor2, myColor3)
});

You can use http://chart.googleapis.com/chart?chst=d_map_pin_letter&chld=•|FF0000, which is a bit easier to decipher, as an alternate URL if you only need to set text and fill color.

khurram's answer refers to a 3rd party site that redirects to the Google Charts API. This means if that person takes down their server you're hosed. I prefer having the flexibility the Google API offers as well as the reliability of going directly to Google. Just make sure you specify a value for each of the colors or it won't work.

In my case, boolean values in my Python dict were the problem. JSON boolean values are in lowercase ("true", "false") whereas in Python they are in Uppercase ("True", "False"). Couldn't find this solution anywhere online but hope it helps.

This is kind of Flex/BlazeDS specific, but here's the solution I've come up with. Sorry if answering my own question is a faux pas.

    HttpServletRequest request = flex.messaging.FlexContext.getHttpRequest();

    Cookie[] cookies = request.getCookies();

    for (Cookie c:cookies)
    {
        log.debug(String.format("Cookie: %s, %s, domain: %s",c.getName(), c.getValue(),c.getDomain()));
    }

It works, I get the cookies. My problem was looking to Spring - BlazeDS had it. Spring probably does too, but I still don't know how to get to it.

If I know for sure in my application that the object is not used in search in any of the list or hash data structure and not used equals method elsewhere except the one used indirectly in hash data structure while adding. Is it advisable to update the existing object in set in equals method. Refer the below code. If I add the this bean to HashSet, I can do group aggregation on the matching object on key (id). By this way I am able to achieve aggregation functions such as sum, max, min, ... as well. If not advisable, please feel free to share me your thoughts.

public class MyBean {

    String id,
           name;
    double amountSpent;

    @Override
    public int hashCode() {
        return id.hashCode();
    }

    @Override
    public boolean equals(Object obj) {
        if(obj!=null && obj instanceof MyBean ) {
            MyBean tmpObj = (MyBean) obj;
            if(tmpObj.id!=null && tmpObj.id.equals(this.id)) {
                tmpObj.amountSpent += this.amountSpent;
                return true;
            }
        }
        return false;
    }
}
