I've had this error as a result of trying to use a cloned VM that had the same SID as the domain. The two options to fix it were: sysprep (or rebuild) the database server OR dcpromo the DC down and back up to change the domain SID.
I'd refrain from using floats for this sort of thing; I'd rather use inline-block
.
Some more points to consider:
<head>
and <body>
doctype
Here's a better way to format your document:
<!DOCTYPE html>
<html>
<head>
<title>Website Title</title>
<style type="text/css">
* {margin: 0; padding: 0;}
#container {height: 100%; width:100%; font-size: 0;}
#left, #middle, #right {display: inline-block; *display: inline; zoom: 1; vertical-align: top; font-size: 12px;}
#left {width: 25%; background: blue;}
#middle {width: 50%; background: green;}
#right {width: 25%; background: yellow;}
</style>
</head>
<body>
<div id="container">
<div id="left">Left Side Menu</div>
<div id="middle">Random Content</div>
<div id="right">Right Side Menu</div>
</div>
</body>
</html>
Here's a jsFiddle for good measure.
If you use Android default action bar then. If you change from java then some time show previous color.
Example
Then your action bar code inside "app_bar_main". So go inside app_bar_main.xml and just add Background.
Example
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#33691e" <!--use your color -->
app:popupTheme="@style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<include layout="@layout/content_main1" />
<html>
<head>
<title>Login page</title>
</head>
<body>
<h1>Simple Login Page</h1>
<form name="login">
Username<input type="text" name="userid"/>
Password<input type="password" name="pswrd"/>
<input type="button" onclick="check(this.form)" value="Login"/>
<input type="reset" value="Cancel"/>
</form>
<script language="javascript">
function check(form) { /*function to check userid & password*/
/*the following code checkes whether the entered userid and password are matching*/
if(form.userid.value == "myuserid" && form.pswrd.value == "mypswrd") {
window.open('target.html')/*opens the target page while Id & password matches*/
}
else {
alert("Error Password or Username")/*displays error message*/
}
}
</script>

If you can't put value on buttons. I have just a rough solution. Put a hidden field. And when one of the buttons are clicked before submitting, populate the value of hidden field with like say 1 when first button clicked and 2 if second one is clicked. and in submit page check for the value of this hidden field to determine which one is clicked.
I have had the same problem and thanks to the posts here I have solved it. I knew that I have around a hundred files and I needed to run it for *.js files only.
find . -type f -name '*.js' -print0 | xargs -0 dos2unix
Thank you all for your help.
FAT32
along with FAT16
and FAT12
are File System Types, but vfat
along with umsdos
and msdos
are drivers, used to mount the FAT file systems in Linux. The choosing of the driver determines how some of the features are applied to the file system, for example, systems mounted with msdos
driver don't have long filenames (they are 8.3 format). vfat
is the most common driver for mounting FAT32 file systems nowadays.
Source: this wikipedia article
Output of commands like df
and lsblk
indeed show vfat
as the File System Type. But sudo file -sL /dev/<partition>
shows FAT (32 bit)
if a File System is FAT32.
You can confirm vfat
is a module and not a File System Type by running modinfo vfat
.
If you've got the PowerShell-based git installation, you can use the Get-Command object to find git:
Get-Command git.exe | Select-Object -ExpandProperty Definition
For windows you can do it like
"scripts": {
"start:prod" : "SET NODE_ENV=production & nodemon app.js",
"start:dev" : "SET NODE_ENV=development & nodemon app.js"
},
Yes, on the server side $_SERVER['DOCUMENT_ROOT']
is equivalent to /
on the client side.
For example: the value of "{$_SERVER['DOCUMENT_ROOT']}/images/thumbnail.png"
will be the string /var/www/html/images/thumbnail.png
on a server where it's local file at that path can be reached from the client side at the url http://example.com/images/thumbnail.png
No, in other words the value of $_SERVER['DOCUMENT_ROOT']
is not /
rather it is the server's local path to what the server shows the client at example.com/
note: $_SERVER['DOCUMENT_ROOT']
does not include a trailing /
yourItem.style['cssProperty']
this way you can call the property string dynamically
You can specify the color
option as a list directly to the plot
function.
from matplotlib import pyplot as plt
from itertools import cycle, islice
import pandas, numpy as np # I find np.random.randint to be better
# Make the data
x = [{i:np.random.randint(1,5)} for i in range(10)]
df = pandas.DataFrame(x)
# Make a list by cycling through the colors you care about
# to match the length of your data.
my_colors = list(islice(cycle(['b', 'r', 'g', 'y', 'k']), None, len(df)))
# Specify this list of colors as the `color` option to `plot`.
df.plot(kind='bar', stacked=True, color=my_colors)
To define your own custom list, you can do a few of the following, or just look up the Matplotlib techniques for defining a color item by its RGB values, etc. You can get as complicated as you want with this.
my_colors = ['g', 'b']*5 # <-- this concatenates the list to itself 5 times.
my_colors = [(0.5,0.4,0.5), (0.75, 0.75, 0.25)]*5 # <-- make two custom RGBs and repeat/alternate them over all the bar elements.
my_colors = [(x/10.0, x/20.0, 0.75) for x in range(len(df))] # <-- Quick gradient example along the Red/Green dimensions.
The last example yields the follow simple gradient of colors for me:
I didn't play with it long enough to figure out how to force the legend to pick up the defined colors, but I'm sure you can do it.
In general, though, a big piece of advice is to just use the functions from Matplotlib directly. Calling them from Pandas is OK, but I find you get better options and performance calling them straight from Matplotlib.
Actually, all of those examples on the web wherein the common content/file type like "js", "css", "img", etc is been used as library name are misleading.
To start, let's look at how existing JSF implementations like Mojarra and MyFaces and JSF component libraries like PrimeFaces and OmniFaces use it. No one of them use resource libraries this way. They use it (under the covers, by @ResourceDependency
or UIViewRoot#addComponentResource()
) the following way:
<h:outputScript library="javax.faces" name="jsf.js" />
<h:outputScript library="primefaces" name="jquery/jquery.js" />
<h:outputScript library="omnifaces" name="omnifaces.js" />
<h:outputScript library="omnifaces" name="fixviewstate.js" />
<h:outputScript library="omnifaces.combined" name="[dynamicname].js" />
<h:outputStylesheet library="primefaces" name="primefaces.css" />
<h:outputStylesheet library="primefaces-aristo" name="theme.css" />
<h:outputStylesheet library="primefaces-vader" name="theme.css" />
It should become clear that it basically represents the common library/module/theme name where all of those resources commonly belong to.
This way it's so much easier to specify and distinguish where those resources belong to and/or are coming from. Imagine that you happen to have a primefaces.css
resource in your own webapp wherein you're overriding/finetuning some default CSS of PrimeFaces; if PrimeFaces didn't use a library name for its own primefaces.css
, then the PrimeFaces own one wouldn't be loaded, but instead the webapp-supplied one, which would break the look'n'feel.
Also, when you're using a custom ResourceHandler
, you can also apply more finer grained control over resources coming from a specific library when library
is used the right way. If all component libraries would have used "js" for all their JS files, how would the ResourceHandler
ever distinguish if it's coming from a specific component library? Examples are OmniFaces CombinedResourceHandler
and GraphicResourceHandler
; check the createResource()
method wherein the library is checked before delegating to next resource handler in chain. This way they know when to create CombinedResource
or GraphicResource
for the purpose.
Noted should be that RichFaces did it wrong. It didn't use any library
at all and homebrewed another resource handling layer over it and it's therefore impossible to programmatically identify RichFaces resources. That's exactly the reason why OmniFaces CombinedResourceHander
had to introduce a reflection-based hack in order to get it to work anyway with RichFaces resources.
Your own webapp does not necessarily need a resource library. You'd best just omit it.
<h:outputStylesheet name="css/style.css" />
<h:outputScript name="js/script.js" />
<h:graphicImage name="img/logo.png" />
Or, if you really need to have one, you can just give it a more sensible common name, like "default" or some company name.
<h:outputStylesheet library="default" name="css/style.css" />
<h:outputScript library="default" name="js/script.js" />
<h:graphicImage library="default" name="img/logo.png" />
Or, when the resources are specific to some master Facelets template, you could also give it the name of the template, so that it's easier to relate each other. In other words, it's more for self-documentary purposes. E.g. in a /WEB-INF/templates/layout.xhtml
template file:
<h:outputStylesheet library="layout" name="css/style.css" />
<h:outputScript library="layout" name="js/script.js" />
And a /WEB-INF/templates/admin.xhtml
template file:
<h:outputStylesheet library="admin" name="css/style.css" />
<h:outputScript library="admin" name="js/script.js" />
For a real world example, check the OmniFaces showcase source code.
Or, when you'd like to share the same resources over multiple webapps and have created a "common" project for that based on the same example as in this answer which is in turn embedded as JAR in webapp's /WEB-INF/lib
, then also reference it as library (name is free to your choice; component libraries like OmniFaces and PrimeFaces also work that way):
<h:outputStylesheet library="common" name="css/style.css" />
<h:outputScript library="common" name="js/script.js" />
<h:graphicImage library="common" name="img/logo.png" />
Another main advantage is that you can apply resource library versioning the right way on resources provided by your own webapp (this doesn't work for resources embedded in a JAR). You can create a direct child subfolder in the library folder with a name in the \d+(_\d+)*
pattern to denote the resource library version.
WebContent
|-- resources
| `-- default
| `-- 1_0
| |-- css
| | `-- style.css
| |-- img
| | `-- logo.png
| `-- js
| `-- script.js
:
When using this markup:
<h:outputStylesheet library="default" name="css/style.css" />
<h:outputScript library="default" name="js/script.js" />
<h:graphicImage library="default" name="img/logo.png" />
This will generate the following HTML with the library version as v
parameter:
<link rel="stylesheet" type="text/css" href="/contextname/javax.faces.resource/css/style.css.xhtml?ln=default&v=1_0" />
<script type="text/javascript" src="/contextname/javax.faces.resource/js/script.js.xhtml?ln=default&v=1_0"></script>
<img src="/contextname/javax.faces.resource/img/logo.png.xhtml?ln=default&v=1_0" alt="" />
So, if you have edited/updated some resource, then all you need to do is to copy or rename the version folder into a new value. If you have multiple version folders, then the JSF ResourceHandler
will automatically serve the resource from the highest version number, according to numerical ordering rules.
So, when copying/renaming resources/default/1_0/*
folder into resources/default/1_1/*
like follows:
WebContent
|-- resources
| `-- default
| |-- 1_0
| | :
| |
| `-- 1_1
| |-- css
| | `-- style.css
| |-- img
| | `-- logo.png
| `-- js
| `-- script.js
:
Then the last markup example would generate the following HTML:
<link rel="stylesheet" type="text/css" href="/contextname/javax.faces.resource/css/style.css.xhtml?ln=default&v=1_1" />
<script type="text/javascript" src="/contextname/javax.faces.resource/js/script.js.xhtml?ln=default&v=1_1"></script>
<img src="/contextname/javax.faces.resource/img/logo.png.xhtml?ln=default&v=1_1" alt="" />
This will force the webbrowser to request the resource straight from the server instead of showing the one with the same name from the cache, when the URL with the changed parameter is been requested for the first time. This way the endusers aren't required to do a hard refresh (Ctrl+F5 and so on) when they need to retrieve the updated CSS/JS resource.
Please note that library versioning is not possible for resources enclosed in a JAR file. You'd need a custom ResourceHandler
. See also How to use JSF versioning for resources in jar.
<input type="checkbox" value="" ng-model="t.IsPullPoint" onclick="return false;" onkeydown="return false;"><span class="cr"></span></label>
In Angular 7, the following simple example would work (assuming dictionary is in a variable called d
):
my.component.ts:
keys: string[] = []; // declaration of class member 'keys'
// component code ...
this.keys = Object.keys(d);
my.component.html: (will display list of key:value pairs)
<ul *ngFor="let key of keys">
{{key}}: {{d[key]}}
</ul>
As a summary, I would describe the wider impact of the repository pattern. It allows all of your code to use objects without having to know how the objects are persisted. All of the knowledge of persistence, including mapping from tables to objects, is safely contained in the repository.
Very often, you will find SQL queries scattered in the codebase and when you come to add a column to a table you have to search code files to try and find usages of a table. The impact of the change is far-reaching.
With the repository pattern, you would only need to change one object and one repository. The impact is very small.
Perhaps it would help to think about why you would use the repository pattern. Here are some reasons:
You have a single place to make changes to your data access
You have a single place responsible for a set of tables (usually)
It is easy to replace a repository with a fake implementation for testing - so you don't need to have a database available to your unit tests
There are other benefits too, for example, if you were using MySQL and wanted to switch to SQL Server - but I have never actually seen this in practice!
To add useful information to the conversation, I came across 404 errors for my bundles in the deployment (it was fine in the local dev environment).
For the bundle names, I including version numbers like such:
bundles.Add(new ScriptBundle("~/bundles/jquerymobile.1.4.3").Include(
...
);
On a whim, I removed all the dots and all was working magically again:
bundles.Add(new ScriptBundle("~/bundles/jquerymobile143").Include(
...
);
Hope that helps someone save some time and frustration.
Instead of .each, another (perhaps more concise) approach to getting all those prices might be:
var prices = $(products).children("li").map(function() {
return $(this).prop("data-price");
}).get();
additionally you may want to consider filtering the array to get rid of empty or non-numeric array values in case they should exist:
prices = prices.filter(function(n){ return(!isNaN(parseFloat(n))) });
then use Sergey's solution above:
var max = Math.max.apply(Math,prices);
var min = Math.min.apply(Math,prices);
In Groovy, null == null
gets a true
. At runtime, you won't know what happened.
In Java, ==
is comparing two references.
This is a cause of big confusion in basic programming, Whether it is safe to use equals. At runtime, a null.equals will give an exception. You've got a chance to know what went wrong.
Especially, you get two values from keys not exist in map(s), ==
makes them equal.
Try creating new instance of customer every time e.g.
while (rs.next()) {
Customer customer = new Customer();
customer.setId(rs.getInt("id"));
customer.setName(rs.getString("name"));
customer.setAddress(rs.getString("address"));
customer.setPhone(rs.getString("phone"));
customer.setEmail(rs.getString("email"));
customer.setBountPoints(rs.getInt("bonuspoint"));
customer.setTotalsale(rs.getInt("totalsale"));
customers.add(customer);
}
The problem has been resolved by running the following in elevated command prompt:
command :
cd C:\Windows\System32\
regtlib msdatsrc.tlb
or
cd C:\Windows\SysWOW64\
regtlib msdatsrc.tlb
I hope this helps.
The literal answer is:
return (value == 1 ? Periods.VariablePeriods : Periods.FixedPeriods);
Note that the inline if statement, just like an if statement, only checks for true or false. If (value == 1) evaluates to false, it might not necessarily mean that value == 2. Therefore it would be safer like this:
return (value == 1
? Periods.VariablePeriods
: (value == 2
? Periods.FixedPeriods
: Periods.Unknown));
If you add more values an inline if will become unreadable and a switch would be preferred:
switch (value)
{
case 1:
return Periods.VariablePeriods;
case 2:
return Periods.FixedPeriods;
}
The good thing about enums is that they have a value, so you can use the values for the mapping, as user854301 suggested. This way you can prevent unnecessary branches thus making the code more readable and extensible.
One doesn't always know the type into which to deserialize. So it would be handy to be able to take any JSON (that contains some array) and dynamically produce a table from that.
An issue can arise however, where the deserializer doesn't know where to look for the array to tabulate. When this happens, we get an error message similar to the following:
Unexpected JSON token when reading DataTable. Expected StartArray, got StartObject. Path '', line 1, position 1.
Even if we give it come encouragement or prepare our json accordingly, then "object" types within the array can still prevent tabulation from occurring, where the deserializer doesn't know how to represent the objects in terms of rows, etc. In this case, errors similar to the following occur:
Unexpected JSON token when reading DataTable: StartObject. Path '[0].__metadata', line 3, position 19.
The below example JSON includes both of these problematic features:
{
"results":
[
{
"Enabled": true,
"Id": 106,
"Name": "item 1",
},
{
"Enabled": false,
"Id": 107,
"Name": "item 2",
"__metadata": { "Id": 4013 }
}
]
}
So how can we resolve this, and still maintain the flexibility of not knowing the type into which to derialize?
Well here is a simple approach I came up with (assuming you are happy to ignore the object-type properties, such as __metadata in the above example):
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
using System.Data;
using System.Linq;
...
public static DataTable Tabulate(string json)
{
var jsonLinq = JObject.Parse(json);
// Find the first array using Linq
var srcArray = jsonLinq.Descendants().Where(d => d is JArray).First();
var trgArray = new JArray();
foreach (JObject row in srcArray.Children<JObject>())
{
var cleanRow = new JObject();
foreach (JProperty column in row.Properties())
{
// Only include JValue types
if (column.Value is JValue)
{
cleanRow.Add(column.Name, column.Value);
}
}
trgArray.Add(cleanRow);
}
return JsonConvert.DeserializeObject<DataTable>(trgArray.ToString());
}
I know this could be more "LINQy" and has absolutely zero exception handling, but hopefully the concept is conveyed.
We're starting to use more and more services at my work that spit back JSON, so freeing ourselves of strongly-typing everything, is my obvious preference because I'm lazy!
You can throw your own custom errors by extending the Exception class.
class CustomException : Exception {
[string] $additionalData
CustomException($Message, $additionalData) : base($Message) {
$this.additionalData = $additionalData
}
}
try {
throw [CustomException]::new('Error message', 'Extra data')
} catch [CustomException] {
# NOTE: To access your custom exception you must use $_.Exception
Write-Output $_.Exception.additionalData
# This will produce the error message: Didn't catch it the second time
throw [CustomException]::new("Didn't catch it the second time", 'Extra data')
}
As of Bootstrap 3.x, there's an example of this in the docs here: http://getbootstrap.com/components/#input-groups-buttons-dropdowns
<div class="input-group">
<input type="text" class="form-control" aria-label="...">
<div class="input-group-btn">
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-expanded="false">Action <span class="caret"></span></button>
<ul class="dropdown-menu dropdown-menu-right" role="menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</div><!-- /btn-group -->
</div><!-- /input-group -->
If we have a greater number of such svg images we can also take the help of font-files.
Sites like https://glyphter.com/ can get us a font file from our svgs.
E.g.
@font-face {
font-family: 'iconFont';
src: url('iconFont.eot');
}
#target{
color: white;
font-size:96px;
font-family:iconFont;
}
In this article, under the title "Using form input for selecting"
http://www.html5rocks.com/en/tutorials/file/dndfiles/
<input type="file" id="files" name="files[]" multiple />
<script>
function handleFileSelect(evt) {
var files = evt.target.files; // FileList object
// files is a FileList of File objects. List some properties.
var output = [];
for (var i = 0, f; f = files[i]; i++) {
// Code to execute for every file selected
}
// Code to execute after that
}
document.getElementById('files').addEventListener('change',
handleFileSelect,
false);
</script>
It adds an event listener to 'change', but I tested it and it triggers even if you choose the same file and not if you cancel.
#include <iostream>
using namespace std;
template <class T>
void merge_sort(T array[],int beg, int end){
if (beg==end){

}
int mid = (beg+end)/2;
merge_sort(array,beg,mid);
merge_sort(array,mid+1,end);
int i=beg,j=mid+1;
int l=end-beg+1;
T *temp = new T [l];

}
delete temp;
}
int main() {

int l = sizeof(array)/sizeof(array[0]);

}
return 0;
}
When we does not want to own the object:
Ex:
class A
{
shared_ptr<int> sPtr1;
weak_ptr<int> wPtr1;
}
In the above class wPtr1 does not own the resource pointed by wPtr1. If the resource is got deleted then wPtr1 is expired.
To avoid circular dependency:
shard_ptr<A> <----| shared_ptr<B> <------
^ | ^ |
| | | |
| | | |
| | | |
| | | |
class A | class B |
| | | |
| ------------ |
| |
-------------------------------------
Now if we make the shared_ptr of the class B and A, the use_count of the both pointer is two.
When the shared_ptr goes out od scope the count still remains 1 and hence the A and B object does not gets deleted.
class B;
class A
{
shared_ptr<B> sP1; // use weak_ptr instead to avoid CD
public:
A() { cout << "A()" << endl; }
~A() { cout << "~A()" << endl; }
void setShared(shared_ptr<B>& p)
{
sP1 = p;
}
};
class B
{
shared_ptr<A> sP1;
public:
B() { cout << "B()" << endl; }
~B() { cout << "~B()" << endl; }
void setShared(shared_ptr<A>& p)
{
sP1 = p;
}
};
int main()
{
shared_ptr<A> aPtr(new A);
shared_ptr<B> bPtr(new B);
aPtr->setShared(bPtr);
bPtr->setShared(aPtr);
return 0;
}
output:
A()
B()
As we can see from the output that A and B pointer are never deleted and hence memory leak.
To avoid such issue just use weak_ptr in class A instead of shared_ptr which makes more sense.
import datetime
datetime.date.today() # Returns 2018-01-15

Well I feel silly, but my problem was that I was in the Debug perspective and they do not show up in that perspective. Switched back to the Java perspective and viola.
It's calling the files included in that particular bundle which is declared inside the BundleConfig
class in the App_Start
folder.
In that particular case The call to @Styles.Render("~/Content/css")
is calling "~/Content/site.css".
bundles.Add(new StyleBundle("~/Content/css").Include("~/Content/site.css"));
What is your output when you do java -version
? This will tell you what version the running JVM is.
The Unsupported major.minor version 51.0 error could mean:
Either way, uninstall all JVM runtimes including JDK and download latest and re-install. That should fix any Unsupported major.minor
error as you will have the lastest JRE and JDK (Maybe even newer then the one used to compile the Servlet)
See: http://www.java.com/en/download/manual.jsp (7 Update 25 )
and here: http://www.oracle.com/technetwork/java/javase/downloads/index.html (Java Platform (JDK) 7u25)
for the latest version of the JRE and JDK respectively.
EDIT:
Most likely your code was written in Java7 however maybe it was done using Java7update4 and your system is running Java7update3. Thus they both are effectively the same major version but the minor versions differ. Only the larger minor version is backward compatible with the lower minor version.
Edit 2 : If you have more than one jdk installed on your pc. you should check that Apache Tomcat is using the same one (jre) you are compiling your programs with. If you installed a new jdk after installing apache it normally won't select the new version.
There's no need to add space before closing quote if path doesn't contain trailing backslash, so following command should work:
robocopy "C:\Source Path" "C:\Destination Path" /option1 /option2...
But, following will not work:
robocopy "C:\Source Path\" "C:\Destination Path\" /option1 /option2...
This is due to the escaping issue that is described here:
The \ escape can cause problems with quoted directory paths that contain a trailing backslash because the closing quote " at the end of the line will be escaped \".
I came accross the same problem and solved it by checking my #includes. If you use QKeyEvent you have to make sure that you also include it.
I had a class like this and my error appeared when working with "event"in the .cpp file.
myfile.h
#include <QKeyEvent> // adding this import solved the problem.
class MyClass : public QWidget
{
Q_OBJECT
public:
MyClass(QWidget* parent = 0);
virtual ~QmitkHelpOverlay();
protected:
virtual void keyPressEvent(QKeyEvent* event);
};
Using various cheats from the web, I came to this solution:
int[] count = new int[1];
final int CHUNK_SIZE = 500;
Map<Integer, List<Long>> chunkedUsers = users.stream().collect( Collectors.groupingBy(
user -> {
count[0]++;
return Math.floorDiv( count[0], CHUNK_SIZE );
} )
);
We use count to mimic a normal collection index.
Then, we group the collection elements in buckets, using the algebraic quotient as bucket number.
The final map contains as key the bucket number, as value the bucket itself.
You can then easily do an operation on each of the buckets with:
chunkedUsers.values().forEach( ... );
After reading the answers here, this is what I ended up with:
public static function isValidEmail(string $email) : bool
{
if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
return false;
}
//Get host name from email and check if it is valid
$email_host = array_slice(explode("@", $email), -1)[0];
// Check if valid IP (v4 or v6). If it is we can't do a DNS lookup
if (!filter_var($email_host,FILTER_VALIDATE_IP, [
'flags' => FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE,
])) {
//Add a dot to the end of the host name to make a fully qualified domain name
// and get last array element because an escaped @ is allowed in the local part (RFC 5322)
// Then convert to ascii (http://us.php.net/manual/en/function.idn-to-ascii.php)
$email_host = idn_to_ascii($email_host.'.');
//Check for MX pointers in DNS (if there are no MX pointers the domain cannot receive emails)
if (!checkdnsrr($email_host, "MX")) {
return false;
}
}
return true;
}
The command to just stream it to a new container (mp4) needed by some applications like Adobe Premiere Pro without encoding (fast) is:
ffmpeg -i input.mov -qscale 0 output.mp4
Alternative as mentioned in the comments, which re-encodes with best quaility (-qscale 0
):
ffmpeg -i input.mov -q:v 0 output.mp4
try something like this :
$.ajax({
type: 'POST',
url: 'loginCheck',
data: $(formLogin).serialize(),
dataType: 'json',
success: function (textStatus, status) {
console.log(textStatus);
console.log(status);
},
error: function(xhr, textStatus, error) {
console.log(xhr.responseText);
console.log(xhr.statusText);
console.log(textStatus);
console.log(error);
}
});
You can use ImportRow
method to copy Row from DataTable to DataTable with the same schema:
var row = SourceTable.Rows[RowNum];
DestinationTable.ImportRow(row);
Update:
With your new Edit, I believe:
var desRow = dataTable.NewRow();
var sourceRow = dataTable.Rows[rowNum];
desRow.ItemArray = sourceRow.ItemArray.Clone() as object[];
will work
The HTML5 spec does allow accessing the webcamera, but last I checked, it is far from finalized, and has very, very little browser support.
This is a link to get you started: http://www.html5rocks.com/en/tutorials/getusermedia/intro/
You'll probably have to use flash if you want it to work cross-browser.
final Properties properties = new Properties();
try (final InputStream stream =
this.getClass().getResourceAsStream("foo.properties")) {
properties.load(stream);
/* or properties.loadFromXML(...) */
}
No need to pass anything in. The function used for addEventListener
will automatically have this
bound to the current element. Simply use this
in your function:
productLineSelect.addEventListener('change', getSelection, false);
function getSelection() {
var value = this.options[this.selectedIndex].value;
alert(value);
}
Here's the fiddle: http://jsfiddle.net/dJ4Wm/
If you want to pass arbitrary data to the function, wrap it in your own anonymous function call:
productLineSelect.addEventListener('change', function() {
foo('bar');
}, false);
function foo(message) {
alert(message);
}
Here's the fiddle: http://jsfiddle.net/t4Gun/
If you want to set the value of this
manually, you can use the call
method to call the function:
var self = this;
productLineSelect.addEventListener('change', function() {
getSelection.call(self);
// This'll set the `this` value inside of `getSelection` to `self`
}, false);
function getSelection() {
var value = this.options[this.selectedIndex].value;
alert(value);
}
It is changed to : from PIL.Image import core as image
for new versions.
If you would like to query all columns
List<Users> list_users = new List<Users>();
MySqlConnection cn = new MySqlConnection("connection");
MySqlCommand cm = new MySqlCommand("select * from users",cn);
try
{
cn.Open();
MySqlDataReader dr = cm.ExecuteReader();
while (dr.Read())
{
list_users.Add(new Users(dr));
}
}
catch { /* error */ }
finally { cn.Close(); }
The User's constructor would do all the "dr.GetString(i)"
When the normType
is NORM_MINMAX
, cv::normalize
normalizes _src
in such a way that the min value of dst
is alpha
and max value of dst
is beta
. cv::normalize
does its magic using only scales and shifts (i.e. adding constants and multiplying by constants).
CV_8UC1
says how many channels dst
has.
The documentation here is pretty clear: http://docs.opencv.org/modules/core/doc/operations_on_arrays.html#normalize
Create a HttpRequestMessage
, set the Method to GET

Method = HttpMethod.Get,
};
request.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue("text/plain"));

I normally use the 'back tick' feature of bash

Note the 'tick' is the 'back tick' e.g. ` not the normal single quote

I don't know the platform you're doing this on but I assume Windows due to the .bat extension.
Also I don't have a way to check this but this seems like the batch processor skips the If lines due to some errors and then executes the one with -dev.
You could try this by chaning the two jump targets (:yes
and :no
) along with the code. If then the line without -dev is executed you know your If lines are erroneous.
If so, please check if ==
is really the right way to do a comparison in .bat
files.
Also, judging from the way bash does this stuff, %foo=="y"
might evaluate to true only if %foo
includes the quotes. So maybe "%foo"=="y"
is the way to go.

in this, I first string the number str()
, which converts it into an inoperable number. Then, I int()
integerize it, to make it an operable number. I just tested your problem on my IDLE GUI, and it said that 49.8 < 50.
Try this:
public static void arrayContains(){
int myArray[]={2,2,5,4,8};
int length=myArray.length;
int toFind = 5;
boolean found = false;
for(int i = 0; i < length; i++) {
if(myArray[i]==toFind) {
found=true;
}
}
System.out.println(myArray.length);
System.out.println(found);
}
Use and empty()
whit negation (for test if not empty)
if(!empty($_GET['id'])) {
// if get id is not empty
}
The names of the first dataframe do not match the names of the second one. Just as the error message says.
> identical(names(xd.small[[1]]), names(xd.small[[2]]) )
[1] FALSE
If you do not care about the names of the 3rd or 4th columns of the second df, you can coerce them to be the same:
> names(xd.small[[1]]) <- names(xd.small[[2]])
> identical(names(xd.small[[1]]), names(xd.small[[2]]) )
[1] TRUE
Then things should proceed happily.
Yes there is. The preferred syntax is to favor str.format
over the deprecated %
operator.
print "First number is {} and second number is {}".format(first, second)
To add to rcs' answer, if you want to use position_dodge() with geom_bar() when x is a POSIX.ct date, you must multiply the width by 86400, e.g.,
ggplot(data=dat, aes(x=Types, y=Number, fill=sample)) +
geom_bar(position = "dodge", stat = 'identity') +
geom_text(aes(label=Number), position=position_dodge(width=0.9*86400), vjust=-0.25)
Observe that errorLogger is a wrapper around logger.trace. But the level of logger is ERROR so logger.trace will not log its message to logger's appenders.
The fix is to change logger.trace to logger.error in the body of errorLogger.
Using Helper class you can access SQLite Database and can perform the various operations on it by overriding the onCreate() and onUpgrade() methods.

This is a known bug in PHP v 5.2 for Windows, it is present at least to version 5.2.3: https://bugs.php.net/bug.php?id=41615
None of the suggested fixes have helped for us, we're going to have to update PHP.
If you know the order of elements in your Set, you can retrieve them by converting the Set to an Array. Something like this:
Set mySet = MyStorageObject.getMyStringSet();
Object[] myArr = mySet.toArray();
String value1 = myArr[0].toString();
String value2 = myArr[1].toString();
Using jQuery I could load image with the check on it's existence. Added src to a plane base64 hash string with original image height width and then replaced it with the required url.
$('[data-src]').each(function() {
var $image_place_holder_element = $(this);
var image_url = $(this).data('src');
$("<div class='hidden-class' />").load(image_url, function(response, status, xhr) {
if (!(status == "error")) {
$image_place_holder_element.removeClass('image-placeholder');
$image_place_holder_element.attr('src', image_url);
}
}).remove();
});
Of course I used and modified few stack answers. Hope it helps someone.
Here's one aspect that could rule the difference:
If you change an element's style in JavaScript, you are affecting the inline style. If there's already a style there, you overwrite it permanently. But, if the style were defined in an external sheet or in a <style>
tag, then setting the inline one to ""
restores the style from that source.
You can use Package Manager Console with command: Uninstall-Package PackageId
to remove it, or just delete package folder from 'packages' folder under solution folder.
More information about Package Manager Console you can find here: http://docs.nuget.org/docs/reference/package-manager-console-powershell-reference
You could use an input mask on the text box, too. If you set the mask to ##/##/####
it will always be formatted as you type and you don't need to do any coding other than checking to see if what was entered was a true date.
Which just a few easy lines
txtUserName.SetFocus
If IsDate(txtUserName.text) Then
Debug.Print Format(CDate(txtUserName.text), "MM/DD/YYYY")
Else
Debug.Print "Not a real date"
End If
To improve upon @EndUzr's response:
To find a foreign port (IPv4 or IPv6) you can use:
netstat -an | findstr /r /c:":N [^:]*$"
To find a local port (IPv4 or IPv6) you can use:
netstat -an | findstr /r /c:":N *[^ ]*:[^ ]* "
Where N is the port number you are interested in. The "/r" switch tells it to process it as regexp. The "/c" switch allows findstr to include spaces within search strings instead of treating a space as a search string delimiter. This added space prevents longer ports being mistreated - for example, ":80" vs ":8080" and other port munging issues.
To list remote connections to the local RDP server, for example:
netstat -an | findstr /r /c:":3389 *[^ ]*:[^ ]*"
Or to see who is touching your DNS:
netstat -an | findstr /r /c:":53 *[^ ]*:[^ ]*"
If you want to exclude local-only ports you can use a series of exceptions with "/v" and escape characters with a backslash:
netstat -an | findstr /v "0.0.0.0 127.0.0.1 \[::\] \[::1\] \*\:\*" | findstr /r /c:":80 *[^ ]*:[^ ]*"
I think if you closed a program
taskkill /f /im "winamp.exe"
//....(winamp.exe is example)...
end, so if you want to start a program that you can use
start "" /normal winamp.exe
(/norma,/max/min are that process value cpu)
ALSO
if you want command line without openning an new window you write that
/B is Start application without creating a new window. The application has ^C handling ignored. Unless the application enables ^C processing, ^Break is the only way to interrupt the application.
In my case the code to show e-mail client window caused Chrome to stop loading images:
document.location.href = mailToLink;
moving it to $(window).load(function () {...}) instead of $(function () {...}) helped.
There are also some ST2/ST3 Plugins for such tasks. I do like these two:
The first one has two methods for removing empty/unnecessary lines. One of them called Delete Surplus Blank Lines
which is cool. It removes only those lines that are followed by another empty line
--- I know this answer is not for this question, but I want people who reads this question and want to handle Services such as Factories to avoid trouble doing this ----
For this you will need to use a Service or a Factory.
The services are the BEST PRACTICE to share data between not nested controllers.
A very very good annotation on this topic about data sharing is how to declare objects. I was unlucky because I fell in a AngularJS trap before I read about it, and I was very frustrated. So let me help you avoid this trouble.
I read from the "ng-book: The complete book on AngularJS" that AngularJS ng-models that are created in controllers as bare-data are WRONG!
A $scope element should be created like this:
angular.module('myApp', [])
.controller('SomeCtrl', function($scope) {
// best practice, always use a model
$scope.someModel = {
someValue: 'hello computer'
});
And not like this:
angular.module('myApp', [])
.controller('SomeCtrl', function($scope) {
// anti-pattern, bare value
$scope.someBareValue = 'hello computer';
};
});
This is because it is recomended(BEST PRACTICE) for the DOM(html document) to contain the calls as
<div ng-model="someModel.someValue"></div> //NOTICE THE DOT.
This is very helpful for nested controllers if you want your child controller to be able to change an object from the parent controller....
But in your case you don't want nested scopes, but there is a similar aspect to get objects from services to the controllers.
Lets say you have your service 'Factory' and in the return space there is an objectA that contains objectB that contains objectC.
If from your controller you want to GET the objectC into your scope, is a mistake to say:
$scope.neededObjectInController = Factory.objectA.objectB.objectC;
That wont work... Instead use only one dot.
$scope.neededObjectInController = Factory.ObjectA;
Then, in the DOM you can call objectC from objectA. This is a best practice related to factories, and most important, it will help to avoid unexpected and non-catchable errors.
While you can use the condition && if-true-part || if-false-part
-syntax in older versions of angular, the usual ternary operator condition ? true-part : false-part
is available in Angular 1.1.5 and later.
Try to use minus sign for count from backside
<script>
$(document).ready(function () {
$('#example-2').DataTable({
'order':[],
'columnDefs': [{
"targets": [-1],
"orderable": false
}]
});
});
</script>
I have this in most Node.JS apps. It also works in the browser.
function log() {
const now = new Date();
const currentDate = `[${now.toISOString()}]: `;
const args = Array.from(arguments);
args.unshift(currentDate);
console.log.apply(console, args);
}
The following code shows how to read values from an HTML form. As @pimvdb said you need to use the request.on('data'...) to capture the contents of the body.
const http = require('http')
const server = http.createServer(function(request, response) {
console.dir(request.param)
if (request.method == 'POST') {
console.log('POST')
var body = ''
request.on('data', function(data) {
body += data
console.log('Partial body: ' + body)
})
request.on('end', function() {
console.log('Body: ' + body)
response.writeHead(200, {'Content-Type': 'text/html'})
response.end('post received')
})
} else {
console.log('GET')
var html = `
<html>
<body>
<form method="post" action="http://localhost:3000">Name:
<input type="text" name="name" />
<input type="submit" value="Submit" />
</form>
</body>
</html>`
response.writeHead(200, {'Content-Type': 'text/html'})
response.end(html)
}
})
const port = 3000
const host = '127.0.0.1'
server.listen(port, host)
console.log(`Listening at http://${host}:${port}`)
If you use something like Express.js and Bodyparser then it would look like this since Express will handle the request.body concatenation
var express = require('express')
var fs = require('fs')
var app = express()
app.use(express.bodyParser())
app.get('/', function(request, response) {
console.log('GET /')
var html = `
<html>
<body>
<form method="post" action="http://localhost:3000">Name:
<input type="text" name="name" />
<input type="submit" value="Submit" />
</form>
</body>
</html>`
response.writeHead(200, {'Content-Type': 'text/html'})
response.end(html)
})
app.post('/', function(request, response) {
console.log('POST /')
console.dir(request.body)
response.writeHead(200, {'Content-Type': 'text/html'})
response.end('thanks')
})
port = 3000
app.listen(port)
console.log(`Listening at http://localhost:${port}`)
Here's Microsoft's write up on using SET IDENTITY_INSERT, which might be helpful to others seeing this post if they, like me, found this post when trying to recreate deleted records while maintaining the original identity column value.

int
to Hex :
Integer.toHexString(intValue);
Hex to int
:
Integer.valueOf(hexString, 16).intValue();
You may also want to use long
instead of int
(if the value does not fit the int
bounds):
Hex to long
:
Long.valueOf(hexString, 16).longValue()
long
to Hex
Long.toHexString(longValue)
I tried this and worked for me.
https://github.com/sedovsek/DataTables-EU-date-Plug-In
I used the format mode .ToString("dd/MM/yyyy");
then in my jQuery.Datatable works fine.
jQ below
oTable = $('#grid').dataTable({
"sPaginationType": "full_numbers",
"aoColumns": [
{ "sType": "eu_date" },
null
]
});
});
The column you have dates, you should define with the sType like the code above.
Update
I've updated this since my original answer, that got the downvote, so I hope this helps. And if it does, hopefully it will get my vote back.
If the headers aren't being imported, you probably have a conflict in the HEADER_SEARCH_PATHS
. Try and add $(inherited)
to the header search paths in your Build Settings to make sure that it pulls in any search paths included in the .xcconfig file from your CocoaPods.
This should help with any conflicts and get your source imported correctly.

Whenever you're confused, I would suggest consulting the Javadoc as the first place for your clarification.
From the javadoc about System
, here's what the doc says:
public final class System
extends Object
The System class contains several useful class fields and methods. It cannot be instantiated.
Among the facilities provided by the System class are standard input, standard output, and error output streams; access to externally defined properties and environment variables; a means of loading files and libraries; and a utility method for quickly copying a portion of an array.
Since:
JDK1.0
Regarding System.out
public static final PrintStream out
The "standard" output stream. This stream is already open and ready to accept output data. Typically this stream corresponds to display output or another output destination specified by the host environment or user.
For simple stand-alone Java applications, a typical way to write a line of output data is:
System.out.println(data)
The way I got around this issue is by not calling intent within a dialog. **** use syntax applicable to activity or fragment accordingly
@Override
public void onClick(DialogInterface dialog, int which) {
checkvariable= true;
getActivity().finish();
}
@Override
public void onStop() {
super.onStop();
if (checkvariable) {
startActivity(intent);
}
}
Follow these steps:
final ActionBar
actionBar = getActionBar();
actionBar.setDisplayShowHomeEnabled(false);
android:logo=@drawable/logo and android:label="@string/actionbar_text"
I think this will help you
string DemoLimit = "02/28/2018";
string pattern = "MM/dd/yyyy";
CultureInfo enUS = new CultureInfo("en-US");
DateTime.TryParseExact(DemoLimit, pattern, enUS,
DateTimeStyles.AdjustToUniversal, out datelimit);

On Xampp 5.6.3 Windows Path C:\xampp\apache\conf\extra\httpd-xampp.conf comment in this: #Require local
New XAMPP security concept ... #Require local ...
I've resolved this using:
.element:before {
font-family: "Font Awesome 5 Free" , "CircularStd";
content: "\f017" " Date";
}
Using the font family "font awesome 5 free" for the icon, and after, We have to specify the font that we are using again because if we doesn't do this, navigator will use the default font (times new roman or something like this).
clip-path
is now (2020) the best way I have found to achieve box-shadows on specific sides of elements, especially when the required effect is a "clean cut" shadow at particular edges, like this:
.shadow-element {
width: 100px;
height: 100px;
background-color: #FFC300;
box-shadow: 0 0 10px 5px rgba(0,0,0,0.75);
clip-path: inset(0px -15px 0px -15px);
/* position and left properties required to bring element out from edge of parent
so that shadow can be seen; margin-left would also achieve the same thing */
position: relative;
left: 15px;
}
_x000D_
<div class="shadow-element"></div>
_x000D_
...as opposed to an attenuated/reduced/thinning shadow like this:
.shadow-element {
width: 100px;
height: 100px;
background-color: #FFC300;
box-shadow: 15px 0 15px -10px rgba(0,0,0,0.75), -15px 0 15px -10px rgba(0,0,0,0.75);
/* position and left properties required to bring element out from edge of parent
so that shadow can be seen; margin-left would also achieve the same thing */
position: relative;
left: 15px;
}
_x000D_
<div class="shadow-element"></div>
_x000D_
Simply apply the following CSS to the element in question:
box-shadow: 0 0 Xpx Ypx [hex/rgba]; /* note 0 offset values */
clip-path: inset(Apx Bpx Cpx Dpx);
Where:
Apx
sets the shadow visibility for the top edgeBpx
rightCpx
bottomDpx
leftEnter a value of 0 for any edges where the shadow should be hidden and a negative value (the same as the combined result of the blur radius + spread values - Xpx + Ypx
) to any edges where the shadow should be displayed.
it's very easy, you just grant the /tmp folder as 777 permission. just type:
chmod -R 777 /tmp
Add this as a first line in the HEAD section of your HTML template

Note that if you care about speed and do not need to worry about singularities, solve()
should be preferred to ginv()
because it is much faster, as you can check:
require(MASS)
mat <- matrix(rnorm(1e6),nrow=1e3,ncol=1e3)
t0 <- proc.time()
inv0 <- ginv(mat)
proc.time() - t0
t1 <- proc.time()
inv1 <- solve(mat)
proc.time() - t1
Use Ctrl+0 to change focus to the sidebar.
The problem is that you aren't correctly escaping the input string, try:
echo "\"member\":\"time\"" | grep -e "member\""
Alternatively, you can use unescaped double quotes within single quotes:
echo '"member":"time"' | grep -e 'member"'
It's a matter of preference which you find clearer, although the second approach prevents you from nesting your command within another set of single quotes (e.g. ssh 'cmd'
).
As per Basil Bourque's comment, this is the updated answer for this question, taking into account the new API of Java 8:
String myDateString = "13:24:40";
LocalTime localTime = LocalTime.parse(myDateString, DateTimeFormatter.ofPattern("HH:mm:ss"));
int hour = localTime.get(ChronoField.CLOCK_HOUR_OF_DAY);
int minute = localTime.get(ChronoField.MINUTE_OF_HOUR);
int second = localTime.get(ChronoField.SECOND_OF_MINUTE);
//prints "hour: 13, minute: 24, second: 40":
System.out.println(String.format("hour: %d, minute: %d, second: %d", hour, minute, second));
Remarks:
====== Below is the old (original) answer for this question, using pre-Java8 API: =====
I'm sorry if I'm gonna upset anyone with this, but I'm actually gonna answer the question. The Java API's are pretty huge, I think it's normal that someone might miss one now and then.
A SimpleDateFormat might do the trick here:
http://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html
It should be something like:
String myDateString = "13:24:40";
//SimpleDateFormat sdf = new SimpleDateFormat("hh:mm:ss");
//the above commented line was changed to the one below, as per Grodriguez's pertinent comment:
SimpleDateFormat sdf = new SimpleDateFormat("HH:mm:ss");
Date date = sdf.parse(myDateString);
Calendar calendar = GregorianCalendar.getInstance(); // creates a new calendar instance
calendar.setTime(date); // assigns calendar to given date
int hour = calendar.get(Calendar.HOUR);
int minute; /... similar methods for minutes and seconds
The gotchas you should be aware of:
the pattern you pass to SimpleDateFormat might be different then the one in my example depending on what values you have (are the hours in 12 hours format or in 24 hours format, etc). Look at the documentation in the link for details on this
Once you create a Date object out of your String (via SimpleDateFormat), don't be tempted to use Date.getHour(), Date.getMinute() etc. They might appear to work at times, but overall they can give bad results, and as such are now deprecated. Use the calendar instead as in the example above.
I would like to recommend flask-empty at GitHub.
It provides an easy way to understand Blueprints, multiple views and extensions.
The SqlDataReader
is a valid data source for the DataTable
. As such, all you need to do its this:
public DataTable GetData()
{
SqlConnection conn = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["BarManConnectionString"].ConnectionString);
conn.Open();
string query = "SELECT * FROM [EventOne]";
SqlCommand cmd = new SqlCommand(query, conn);
DataTable dt = new DataTable();
dt.Load(cmd.ExecuteReader());
conn.Close();
return dt;
}
Methods and variables that are not declared as static are known as instance methods and instance variables. To refer to instance methods and variables, you must instantiate the class first means you should create an object of that class first.For static you don't need to instantiate the class u can access the methods and variables with the class name using period sign which is in (.)
for example:
Person.staticMethod(); //accessing static method.
for non-static method you must instantiate the class.
Person person1 = new Person(); //instantiating
person1.nonStaticMethod(); //accessing non-static method.
