With the code in the question, you're only dealing interacting with the first of the four entries returned by that selector.
Code below as a fiddle: https://jsfiddle.net/c4nhpqgb/
I want to be overly clear that you have four items that matched that selector, so you need to deal with each explicitly. Using eq()
is a little more explicit making this point than the answers using map
, though map
or each
is what you'd probably use "in real life" (jquery docs for eq
here).

<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js" ></script>

<div class="mbox">Block Two</div>
<div class="mbox">Block Three</div>
<div class="mbox">Block Four</div>
<div id="outige"></div>
<script>
// using the $ prefix to use the "jQuery wrapped var" convention
var i, $mvar = $('.mbox');
// convenience method to display unprocessed html on the same page
function logit( string )
{
var text = document.createTextNode( string );
$('#outige').append(text);
$('#outige').append("<br>");
}
logit($mvar.length);
for (i=0; i<$mvar.length; i++) {
logit($mvar.eq(i).html());
}
</script>

Maybe you'll be able to set the event handlers programmatically, using something like (pseudocode)
sub myhandler(eventsource)
process(eventsource.value)
end sub
for each cell
cell.setEventHandler(myHandler)
But i dont know the syntax for achieving this in VB/VBA, or if is even possible.

Assuming that you have a collection ${roles} of the elements to put in the combo, and ${selected} the selected element, It would go like this:
<select name='role'>
<option value="${selected}" selected>${selected}</option>
<c:forEach items="${roles}" var="role">
<c:if test="${role != selected}">
<option value="${role}">${role}</option>
</c:if>
</c:forEach>
</select>
UPDATE (next question)
You are overwriting the attribute "productSubCategoryName". At the end of the for loop, the last productSubCategoryName.
Because of the limitations of the expression language, I think the best way to deal with this is to use a map:
Map<String,Boolean> map = new HashMap<String,Boolean>();
for(int i=0;i<userProductData.size();i++){
String productSubCategoryName=userProductData.get(i).getProductSubCategory();
System.out.println(productSubCategoryName);
map.put(productSubCategoryName, true);
}
request.setAttribute("productSubCategoryMap", map);
And then in the JSP:
<select multiple="multiple" name="prodSKUs">
<c:forEach items="${productSubCategoryList}" var="productSubCategoryList">
<option value="${productSubCategoryList}" ${not empty productSubCategoryMap[productSubCategoryList] ? 'selected' : ''}>${productSubCategoryList}</option>
</c:forEach>
</select>
It means XML namespace.
Basically, every element (or attribute) in XML belongs to a namespace, a way of "qualifying" the name of the element.
Imagine you and I both invent our own XML. You invent XML to describe people, I invent mine to describe cities. Both of us include an element called name
. Yours refers to the person’s name, and mine to the city name—OK, it’s a little bit contrived.
<person>
<name>Rob</name>
<age>37</age>
<homecity>
<name>London</name>
<lat>123.000</lat>
<long>0.00</long>
</homecity>
</person>
If our two XMLs were combined into a single document, how would we tell the two names apart? As you can see above, there are two name
elements, but they both have different meanings.
The answer is that you and I would both assign a namespace to our XML, which we would make unique:
<personxml:person xmlns:personxml="http://www.your.example.com/xml/person"
xmlns:cityxml="http://www.my.example.com/xml/cities">
<personxml:name>Rob</personxml:name>
<personxml:age>37</personxml:age>
<cityxml:homecity>
<cityxml:name>London</cityxml:name>
<cityxml:lat>123.000</cityxml:lat>
<cityxml:long>0.00</cityxml:long>
</cityxml:homecity>
</personxml:person>
Now we’ve fully qualified our XML, there is no ambiguity as to what each name
element means. All of the tags that start with personxml:
are tags belonging to your XML, all the ones that start with cityxml:
are mine.
There are a few points to note:
If you exclude any namespace declarations, things are considered to be in the default namespace.
If you declare a namespace without the identifier, that is, xmlns="http://somenamespace"
, rather than xmlns:rob="somenamespace"
, it specifies the default namespace for the document.
The actual namespace itself, often a IRI, is of no real consequence. It should be unique, so people tend to choose a IRI/URI that they own, but it has no greater meaning than that. Sometimes people will place the schema (definition) for the XML at the specified IRI, but that is a convention of some people only.
The prefix is of no consequence either. The only thing that matters is what namespace the prefix is defined as. Several tags beginning with different prefixes, all of which map to the same namespace are considered to be the same.
For instance, if the prefixes personxml
and mycityxml
both mapped to the same namespace (as in the snippet below), then it wouldn't matter if you prefixed a given element with personxml
or mycityxml
, they'd both be treated as the same thing by an XML parser. The point is that an XML parser doesn't care what you've chosen as the prefix, only the namespace it maps too. The prefix is just an indirection pointing to the namespace.
<personxml:person
xmlns:personxml="http://example.com/same/url"
xmlns:mycityxml="http://example.com/same/url" />
Attributes can be qualified but are generally not. They also do not inherit their namespace from the element they are on, as opposed to elements (see below).
Also, element namespaces are inherited from the parent element. In other words I could equally have written the above XML as
<person xmlns="http://www.your.example.com/xml/person">
<name>Rob</name>
<age>37</age>
<homecity xmlns="http://www.my.example.com/xml/cities">
<name>London</name>
<lat>123.000</lat>
<long>0.00</long>
</homecity>
</person>
Math.max() is actually as3 code compiled to AVM2 opcodes, and as such is not more "native" than any other as3 code. As a consequence, it is not necessarily the fastest implementation.
Actually, given that it works on Array type, it is slower than carefully written code usign Vector:
I did a quick benchmark comparison of several naive Vector and Array implementations of Math.max, using gskinner's PerformanceTest (Vector and Array being filled with identical random Numbers). The fastest Vector implementation appeared to be more than 3x faster than Math.max with recent AIR SDK/release player (flash player WIN 14,0,0,122 RELEASE, compiled with AIR SDK 14):
average 3.5 ms for 1,000,000 values, compared to Math.max() average of 11ms :
function max(values:Vector.<Number>):Number
{
var max:Number = Number.MIN_VALUE;
var length:uint = values.length;
for (var i:uint = 0; i < length ; ++i)
if (values[i] > max)
max = values[i];
return max;
}
Conclusion is that if you are concerned by performance, you should use Vector over Array anywhere you can in the first place, and not always rely on default implementations, especially when they force the use of Array
PS:same implementation with a for each() loop is 12x slower ...!

In Bootstrap 4, if you want to do something like this:
Mobile | Desktop
-----------------------------
A | A
C | B C
B | D
D |
You need to reverse the order of B then C then apply order-{breakpoint}-first
to B. And apply two different settings, one that will make them share the same cols and other that will make them take the full width of the 12 cols:
Smaller screens: 12 cols to B and 12 cols to C
Larger screens: 12 cols between the sum of them (B + C = 12)
Like this
<div class='row no-gutters'>
<div class='col-12'>
A
</div>
<div class='col-12'>
<div class='row no-gutters'>
<div class='col-12 col-md-6'>
C
</div>
<div class='col-12 col-md-6 order-md-first'>
B
</div>
</div>
</div>
<div class='col-12'>

First of all, it's actually not accurate to say that
x % 2 == x & 1
Simple counterexample: x = -1
. In many languages, including Java, -1 % 2 == -1
. That is, %
is not necessarily the traditional mathematical definition of modulo. Java calls it the "remainder operator", for example.
With regards to bitwise optimization, only modulo powers of two can "easily" be done in bitwise arithmetics. Generally speaking, only modulo powers of base b can "easily" be done with base b representation of numbers.
In base 10, for example, for non-negative N
, N mod 10^k
is just taking the least significant k
digits.
The mipmap folders are for placing your app/launcher icons (which are shown on the homescreen) in only. Any other drawable assets you use should be placed in the relevant drawable folders as before.
According to this Google blogpost:
It’s best practice to place your app icons in mipmap- folders (not the drawable- folders) because they are used at resolutions different from the device’s current density.
When referencing the mipmap- folders ensure you are using the following reference:
android:icon="@mipmap/ic_launcher"
The reason they use a different density is that some launchers actually display the icons larger than they were intended. Because of this, they use the next size up.

According to this website (the second awnser) it suggest that you are trying to execute the query with a missing parameter.
For instance :
exec SomeStoredProcedureThatReturnsASite( :L_kSite );
You are trying to execute the query without the last parameter.
Maybe in SQLPlus
it doesn't have the same requirements, so it might have been a luck that it worked there.
@Entity(name = "someThing") => this name will be used to name the Entity @Table(name = "someThing") => this name will be used to name a table in DB
So, in the first case your table and entity will have the same name, that will allow you to access your table with the same name as the entity while writing HQL or JPQL.
And in second case while writing queries you have to use the name given in @Entity and the name given in @Table will be used to name the table in the DB.
So in HQL your someThing will refer to otherThing in the DB.
HEAD
is not the latest revision, it's the current revision. Usually, it's the latest revision of the current branch, but it doesn't have to be.
master
is a name commonly given to the main branch, but it could be called anything else (or there could be no main branch).
origin
is a name commonly given to the main remote. remote is another repository that you can pull from and push to. Usually it's on some server, like github.
The session.save(object) returns the id of the object, or you could alternatively call the id getter method after performing a save.
Save() return value:
Serializable save(Object object) throws HibernateException
Returns:
the generated identifier
Getter method example:
UserDetails entity:
@Entity
public class UserDetails {
@Id
@GeneratedValue
private int id;
private String name;
// Constructor, Setters & Getters
}
Logic to test the id's :
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
session.getTransaction().begin();
UserDetails user1 = new UserDetails("user1");
UserDetails user2 = new UserDetails("user2");
//int userId = (Integer) session.save(user1); // if you want to save the id to some variable
System.out.println("before save : user id's = "+user1.getId() + " , " + user2.getId());
session.save(user1);
session.save(user2);
System.out.println("after save : user id's = "+user1.getId() + " , " + user2.getId());
session.getTransaction().commit();
Output of this code:
before save : user id's = 0 , 0
after save : user id's = 1 , 2
As per this output, you can see that the id's were not set before we save the UserDetails
entity, once you save the entities then Hibernate set's the id's for your objects - user1
and user2
You can try one even more simple:
<option value="1" ${item.quantity == 1 ? "selected" : ""}>1</option>

Assuming you already know lists are of equal size, the following will guarantee True if and only if two vectors are exactly the same (including order)
functools.reduce(lambda b1,b2: b1 and b2, map(lambda e1,e2: e1==e2, listA, ListB), True)
Example:
>>> from functools import reduce
>>> def compvecs(a,b):
... return reduce(lambda b1,b2: b1 and b2, map(lambda e1,e2: e1==e2, a, b), True)
...
>>> compvecs(a=[1,2,3,4], b=[1,2,4,3])
False
>>> compvecs(a=[1,2,3,4], b=[1,2,3,4])
True
>>> compvecs(a=[1,2,3,4], b=[1,2,4,3])
False
>>> compare_vectors(a=[1,2,3,4], b=[1,2,2,4])
False
>>>
Note that as of Microsoft SQL Server 2016, UTF-8 is supported by bcp
, BULK_INSERT
, and OPENROWSET
.
Addendum 2016-12-21: SQL Server 2016 SP1 now enables Unicode Compression (and most other previously Enterprise-only features) for all versions of MS SQL including Standard and Express. This is not the same as UTF-8 support, but it yields a similar benefit if the goal is disk space reduction for Western alphabets.

R defines a ~
(tilde) operator for use in formulas. Formulas have all sorts of uses, but perhaps the most common is for regression:
library(datasets)
lm( myFormula, data=iris)
help("~")
or help("formula")
will teach you more.
@Spacedman has covered the basics. Let's discuss how it works.
First, being an operator, note that it is essentially a shortcut to a function (with two arguments):
> `~`(lhs,rhs)
lhs ~ rhs
> lhs ~ rhs
lhs ~ rhs
That can be helpful to know for use in e.g. apply
family commands.
Second, you can manipulate the formula as text:
oldform <- as.character(myFormula) # Get components
myFormula <- as.formula( paste( oldform[2], "Sepal.Length", sep="~" ) )
Third, you can manipulate it as a list:
myFormula[[2]]
myFormula[[3]]
Finally, there are some helpful tricks with formulae (see help("formula")
for more):
myFormula <- Species ~ .
For example, the version above is the same as the original version, since the dot means "all variables not yet used." This looks at the data.frame you use in your eventual model call, sees which variables exist in the data.frame but aren't explicitly mentioned in your formula, and replaces the dot with those missing variables.
The Replace
operator means Replace something with something else; do not be confused with removal functionality.
Also you should send the result processed by the operator to a variable or to another operator. Neither .Replace()
, nor -replace
modifies the original variable.
To remove all spaces, use 'Replace any space symbol with empty string'
$string = $string -replace '\s',''
To remove all spaces at the beginning and end of the line, and replace all double-and-more-spaces or tab symbols to spacebar symbol, use
$string = $string -replace '(^\s+|\s+$)','' -replace '\s+',' '
or the more native System.String
method
$string = $string.Trim()
Regexp is preferred, because ' '
means only 'spacebar' symbol, and '\s'
means 'spacebar, tab and other space symbols'. Note that $string.Replace()
does 'Normal' replace, and $string -replace
does RegEx replace, which is more heavy but more functional.
Note that RegEx have some special symbols like dot (.
), braces ([]()
), slashes (\
), hats (^
), mathematical signs (+-
) or dollar signs ($
) that need do be escaped. ( 'my.space.com' -replace '\.','-'
=> 'my-space-com'
. A dollar sign with a number (ex $1
) must be used on a right part with care
'2033' -replace '(\d+)',$( 'Data: $1')
Data: 2033
UPDATE: You can also use $str = $str.Trim()
, along with TrimEnd()
and TrimStart()
. Read more at System.String MSDN page.
You can find <div>

From the documentation:
contentType (default: 'application/x-www-form-urlencoded; charset=UTF-8')
Type: String
When sending data to the server, use this content type. Default is "application/x-www-form-urlencoded; charset=UTF-8", which is fine for most cases. If you explicitly pass in a content-type to $.ajax(), then it'll always be sent to the server (even if no data is sent). If no charset is specified, data will be transmitted to the server using the server's default charset; you must decode this appropriately on the server side.
and:
dataType (default: Intelligent Guess (xml, json, script, or html))
Type: String
The type of data that you're expecting back from the server. If none is specified, jQuery will try to infer it based on the MIME type of the response (an XML MIME type will yield XML, in 1.4 JSON will yield a JavaScript object, in 1.4 script will execute the script, and anything else will be returned as a string).
They're essentially the opposite of what you thought they were.
I think what you're trying to do is wrap loooooooooooooong words or URLs so they don't push the size of the table out. (I've just been trying to do the same thing!)
You can do this easily with a DIV by giving it the style word-wrap: break-word
(and you may need to set its width, too).
div {
word-wrap: break-word; /* All browsers since IE 5.5+ */
overflow-wrap: break-word; /* Renamed property in CSS3 draft spec */
width: 100%;
}
However, for tables, you must either wrap the content in a DIV (or other block tag) or apply: table-layout: fixed
. This means the columns widths are no longer fluid, but are defined based on the widths of the columns in the first row only (or via specified widths). Read more here.
Sample code:
table {
table-layout: fixed;
width: 100%;
}
table td {
word-wrap: break-word; /* All browsers since IE 5.5+ */
overflow-wrap: break-word; /* Renamed property in CSS3 draft spec */
}
Hope that helps somebody.

I use a tool called Prepo to produce all the right image sizes. You simply feed the app you image file and it will spit out each necessary file with an appropriate name.
Once you do this, you can then drag in the appropriate files or simply point to your Prepo exported folder.
To answer people thinking you "have to" use vector
instead of unique_ptr
I have a case in CUDA programming on GPU when you allocate memory in Device you must go for a pointer array (with cudaMalloc
).
Then, when retrieving this data in Host, you must go again for a pointer and unique_ptr
is fine to handle pointer easily.
The extra cost of converting double*
to vector<double>
is unnecessary and leads to a loss of perf.
If you want to test the user agent, the correct way is to, test the user agent, i.e. test navigator.userAgent
.
If the user
fakes this they are not due concern. If you test.isUnix()
you should not subsequently have to worry if the system is Unix.
As a user changing userAgent is also fine, but you don't expect sites to render properly if you do.
If you wish to provide support for Microsoft browsers you should ensure the first few characters of the content includes and test every page you write.
Bottom line... Always code to the standards. Then hack it until it works in the current version of IE & don't expect it to look good. That's what GitHub does, and they just got given 100 million bucks.

and in your root project folder in (hidden) folder: .vs/config/applicationhost.config
you need add row to "site" tag:
<binding protocol="http" bindingInformation="*:8080:192.xxx.xxx.xxx" />
open "internet information services (iis) manager"
(to find it: in search in taskbar write "Turn Window features on or off" and open result and then check the checkbox "internet information service" and install that):

I did not like that it new'd the Include method on bundle, and that it created temporary files in the content directory. (they ended up getting checked in, deployed, then the service wouldn't start!)
So to follow the design of Bundling, I elected to perform essentially the same code, but in an IBundleTransform implementation::
class StyleRelativePathTransform
: IBundleTransform
{
public StyleRelativePathTransform()
{
}
public void Process(BundleContext context, BundleResponse response)
{
response.Content = String.Empty;
Regex pattern = new Regex(@"url\s*\(\s*([""']?)([^:)]+)\1\s*\)", RegexOptions.IgnoreCase);
// open each of the files
foreach (FileInfo cssFileInfo in response.Files)
{
if (cssFileInfo.Exists)
{
// apply the RegEx to the file (to change relative paths)
string contents = File.ReadAllText(cssFileInfo.FullName);
MatchCollection matches = pattern.Matches(contents);
// Ignore the file if no match
if (matches.Count > 0)
{
string cssFilePath = cssFileInfo.DirectoryName;
string cssVirtualPath = context.HttpContext.RelativeFromAbsolutePath(cssFilePath);
foreach (Match match in matches)
{
// this is a path that is relative to the CSS file
string relativeToCSS = match.Groups[2].Value;
// combine the relative path to the cssAbsolute
string absoluteToUrl = Path.GetFullPath(Path.Combine(cssFilePath, relativeToCSS));
// make this server relative
string serverRelativeUrl = context.HttpContext.RelativeFromAbsolutePath(absoluteToUrl);
string quote = match.Groups[1].Value;
string replace = String.Format("url({0}{1}{0})", quote, serverRelativeUrl);
contents = contents.Replace(match.Groups[0].Value, replace);
}
}
// copy the result into the response.
response.Content = String.Format("{0}\r\n{1}", response.Content, contents);
}
}
}
}
And then wrapped this up in a Bundle Implemetation:
public class StyleImagePathBundle
: Bundle
{
public StyleImagePathBundle(string virtualPath)
: base(virtualPath)
{
base.Transforms.Add(new StyleRelativePathTransform());
base.Transforms.Add(new CssMinify());
}
public StyleImagePathBundle(string virtualPath, string cdnPath)
: base(virtualPath, cdnPath)
{
base.Transforms.Add(new StyleRelativePathTransform());
base.Transforms.Add(new CssMinify());
}
}
Sample Usage:
static void RegisterBundles(BundleCollection bundles)
{
...
bundles.Add(new StyleImagePathBundle("~/bundles/Bootstrap")
.Include(
"~/Content/css/bootstrap.css",
"~/Content/css/bootstrap-responsive.css",
"~/Content/css/jquery.fancybox.css",
"~/Content/css/style.css",
"~/Content/css/error.css",
"~/Content/validation.css"
));
Here is my extension method for RelativeFromAbsolutePath:
public static string RelativeFromAbsolutePath(this HttpContextBase context, string path)
{
var request = context.Request;
var applicationPath = request.PhysicalApplicationPath;
var virtualDir = request.ApplicationPath;
virtualDir = virtualDir == "/" ? virtualDir : (virtualDir + "/");
return path.Replace(applicationPath, virtualDir).Replace(@"\", "/");
}
You can try this code for send json string
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:ARRAY_CONTAIN_JSON_STRING options:NSJSONWritin*emphasized text*gPrettyPrinted error:NULL];
NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
NSString *WS_test = [NSString stringWithFormat:@"www.test.com?xyz.php¶m=%@",jsonString];
Use urlencode()
rather than trying to implement your own. Be lazy.
Put your SSH key into your Jenkins profile, then use the declarative linter as follows:
ssh jenkins.hostname.here declarative-linter < Jenkinsfile
This will do a static analysis on your Jenkinsfile. In the editor of your choice, define a keyboard shortcut that runs that command automatically. In Visual Studio Code, which is what I use, go to Tasks > Configure Tasks, then use the following JSON to create a Validate Jenkinsfile command:
{
"version": "2.0.0",
"tasks": [
{
"label": "Validate Jenkinsfile",
"type": "shell",
"command": "ssh jenkins.hostname declarative-linter < ${file}"
}
]
}
string[][] languages = new string[2][];
languages[0] = new string[2];
languages[1] = new string[3];
// inserting data into double dimensional arrays.
for (int i = 0; i < 2; i++)
{
languages[0][i] = "Jagged"+i.ToString();
}
for (int j = 0; j < 3; j++)
{
languages[1][j] = "Jag"+j.ToString();
}
// doing foreach through 2 dimensional arrays.
foreach (string[] s in languages)
{
foreach (string a in s)
{
Console.WriteLine(a);
}
}
You cannot use next() in this scenario, if you look at the documentation it says:
Next() Get the immediately following sibling of each element in the set of matched elements. If a selector is provided, it retrieves the next sibling that matches the selector.
so if the second DIV was in the same TD then you could code:
// Won't work in your case
$(obj).next().filter('.class');
$(obj).parents('table').find('.class')
You can specify minDate as today by adding minDate: 0
to the options.
$("input.DateFrom").datepicker({
minDate: 0,
...
});
If you want to keep only numbers then use /[^0-9]+/
instead of /[^a-zA-Z]+/
I figured out this workaround:
>>> p = subprocess.Popen(['grep','f'],stdout=subprocess.PIPE,stdin=subprocess.PIPE)
>>> p.stdin.write(b'one\ntwo\nthree\nfour\nfive\nsix\n') #expects a bytes type object
>>> p.communicate()[0]
'four\nfive\n'
>>> p.stdin.close()
Is there a better one?
The answer of ADTC works fine, but I've find another solution, so I post it here if someone wants something different.
I think ADTC's solution is better, but mine's also works.
Here is the other solution I found
select p.name
from person p
where instr(p.name,chr(8211)) > 0; --contains the character chr(8211)
--at least 1 time
Thank you.
Based on the given answers and information in the question, this is the code you should use:
public static boolean doesURLExist(URL url) throws IOException
{
// We want to check the current URL
HttpURLConnection.setFollowRedirects(false);
HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
// We don't need to get data
httpURLConnection.setRequestMethod("HEAD");
// Some websites don't like programmatic access so pretend to be a browser
httpURLConnection.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1.2) Gecko/20090729 Firefox/3.5.2 (.NET CLR 3.5.30729)");
int responseCode = httpURLConnection.getResponseCode();
// We only accept response code 200
return responseCode == HttpURLConnection.HTTP_OK;
}
Of course tested and working.
If every input asks the same question, you should use a for
loop and an array of inputs:
Scanner dd = new Scanner(System.in);
int[] vars = new int[3];
for(int i = 0; i < vars.length; i++) {
System.out.println("Enter next var: ");
vars[i] = dd.nextInt();
}
Or as Chip suggested, you can parse the input from one line:
Scanner in = new Scanner(System.in);
int[] vars = new int[3];
System.out.println("Enter "+vars.length+" vars: ");
for(int i = 0; i < vars.length; i++)
vars[i] = in.nextInt();
You were on the right track, and what you did works. This is just a nicer and more flexible way of doing things.

Javascript doesn't have it, as you point out.
A quick search came up with:
function strcmp ( str1, str2 ) {
// http://kevin.vanzonneveld.net
// + original by: Waldo Malqui Silva
// + input by: Steve Hilder
// + improved by: Kevin van Zonneveld (http://kevin.vanzonneveld.net)
// + revised by: gorthaur
// * example 1: strcmp( 'waldo', 'owald' );
// * returns 1: 1
// * example 2: strcmp( 'owald', 'waldo' );
// * returns 2: -1
return ( ( str1 == str2 ) ? 0 : ( ( str1 > str2 ) ? 1 : -1 ) );
}
from http://kevin.vanzonneveld.net/techblog/article/javascript_equivalent_for_phps_strcmp/
Of course, you could just add localeCompare if needed:
if (typeof(String.prototype.localeCompare) === 'undefined') {
String.prototype.localeCompare = function(str, locale, options) {
return ((this == str) ? 0 : ((this > str) ? 1 : -1));
};
}
And use str1.localeCompare(str2)
everywhere, without having to worry wether the local browser has shipped with it. The only problem is that you would have to add support for locales
and options
if you care about that.
Use the replace()
method on string:
>>> stuff = "Big and small"
>>> stuff.replace( " and ", "/" )
'Big/small'
They have semantic difference - a <div>
element is designed to describe a container of data whereas a <p>
element is designed to describe a paragraph of content.
The semantics make all the difference. HTML is a markup language which means that it is designed to "mark up" content in a way that is meaningful to the consumer of the markup. Most developers believe that the semantics of the document are the default styles and rendering that browsers apply to these elements but that is not the case.
The elements that you choose to mark up your content should describe the content. Don't mark up your document based on how it should look - mark it up based on what it is.
If you need a generic container purely for layout purposes then use a <div>
. If you need an element to describe a paragraph of content then use a <p>
.
Note: It is important to understand that both <div>
and <p>
are block-level elements which means that most browsers will treat them in a similar fashion.
Here are two other software packages which can be used for DNS caching on Linux:
After configuring the software for DNS forwarding and caching, you then set the system's DNS resolver to 127.0.0.1 in /etc/resolv.conf.
If your system is using NetworkManager you can either try using the dns=dnsmasq
option in /etc/NetworkManager/NetworkManager.conf
or you can change your connection settings to Automatic (Address Only) and then use a script in the /etc/NetworkManager/dispatcher.d
directory to get the DHCP nameserver, set it as the DNS forwarding server in your DNS cache software and then trigger a configuration reload.
"s" is not a "char*", it's a "char[4]". And so, "&s" is not a "char**", but actually "a pointer to an array of 4 characater". Your compiler may treat "&s" as if you had written "&s[0]", which is roughly the same thing, but is a "char*".
When you write "char** p = &s;" you are trying to say "I want p to be set to the address of the thing which currently points to "asd". But currently there is nothing which points to "asd". There is just an array which holds "asd";
char s[] = "asd";
char *p = &s[0]; // alternately you could use the shorthand char*p = s;
char **pp = &p;
While Building a Project, if in the project properties it shows that it is build under Target.NET Framework 4.5, update it to 4.6 or 4.6.1. Then the build will be able to locate Entity Framework 6.0 in the Web.config file. This approach solved my problem. Selecting Target framework from Project Properties
In addition to the differences mentioned in other answers, there also is a speed difference. d = {} is over twice as fast:
python -m timeit -s "d = {}" "for i in xrange(500000): d.clear()"
10 loops, best of 3: 127 msec per loop
python -m timeit -s "d = {}" "for i in xrange(500000): d = {}"
10 loops, best of 3: 53.6 msec per loop
In many cases, you have an interface and pass along an object that implements it. Dialogs for example have the OnClickListener.
Just as a random example:
// The callback interface
interface MyCallback {
void callbackCall();
}
// The class that takes the callback
class Worker {
MyCallback callback;
void onEvent() {
callback.callbackCall();
}
}
// Option 1:
class Callback implements MyCallback {
void callbackCall() {
// callback code goes here
}
}
worker.callback = new Callback();
// Option 2:
worker.callback = new MyCallback() {
void callbackCall() {
// callback code goes here
}
};
I probably messed up the syntax in option 2. It's early.
I had the same issue. The problem was, the performSegueWithIdentifier was triggered by a notification, as soon as I put the notification on the main thread the warning message was gone.
Your second question is easy, GET has a size limitation of 1-2 kilobytes on both the server and browser side, so any kind of larger amounts of data you'd have to send through POST.
Chaining conditions creates long lines, which are discouraged by pep8. Using the .query method forces to use strings, which is powerful but unpythonic and not very dynamic.
Once each of the filters is in place, one approach is
import numpy as np
import functools
def conjunction(*conditions):
return functools.reduce(np.logical_and, conditions)
c_1 = data.col1 == True
c_2 = data.col2 < 64
c_3 = data.col3 != 4
data_filtered = data[conjunction(c1,c2,c3)]
np.logical operates on and is fast, but does not take more than two arguments, which is handled by functools.reduce.
Note that this still has some redundancies: a) shortcutting does not happen on a global level b) Each of the individual conditions runs on the whole initial data. Still, I expect this to be efficient enough for many applications and it is very readable.
You can also make a disjunction (wherein only one of the conditions needs to be true) by using np.logical_or
instead:
import numpy as np
import functools
def disjunction(*conditions):
return functools.reduce(np.logical_or, conditions)
c_1 = data.col1 == True
c_2 = data.col2 < 64
c_3 = data.col3 != 4
data_filtered = data[disjunction(c1,c2,c3)]
To expand on RiggsFolly’s answer—or for anyone who is facing the same issue but is using Apache 2.2 or below—this format should work well:
Order Deny,Allow
Deny from all
Allow from 127.0.0.1 ::1
Allow from localhost
Allow from 192.168
Allow from 10
Satisfy Any
For more details on the format changes for Apache 2.4, the official Upgrading to 2.2 from 2.4 page is pretty clear & concise. Key point being:
The old access control idioms should be replaced by the new authentication mechanisms, although for compatibility with old configurations, the new module
mod_access_compat
is provided.
Which means, system admins around the world don’t necessarily have to panic about changing Apache 2.2 configs to be 2.4 compliant just yet.
Python3's range is Python2's xrange. There's no need to wrap an iter around it. To get an actual list in Python3, you need to use list(range(...))
If you want something that works with Python2 and Python3, try this
try:
xrange
except NameError:
xrange = range
public static void PrintFileToDefaultPrinter(string FilePath)
{
try
{
var file = File.ReadAllBytes(FilePath);
var printQueue = LocalPrintServer.GetDefaultPrintQueue();
using (var job = printQueue.AddJob())
using (var stream = job.JobStream)
{
stream.Write(file, 0, file.Length);
}
}
catch (Exception)
{
throw;
}
}
This question is already answered and most of the answers here are correct but they don't solve one major issue with config changes. Have a look at this article https://androidresearch.wordpress.com/2013/05/10/dealing-with-asynctask-and-screen-orientation/ if you would like to write a async task in a better way.
None of these answers mention the colClasses
argument which is another way to specify the variable classes in read.csv
.
stuckey <- read.csv("C:/kalle/R/stuckey.csv", colClasses = "numeric") # all variables to numeric
or you can specify which columns to convert:
stuckey <- read.csv("C:/kalle/R/stuckey.csv", colClasses = c("PTS" = "numeric", "MP" = "numeric") # specific columns to numeric
Note that if a variable can't be converted to numeric then it will be converted to factor as default which makes it more difficult to convert to number. Therefore, it can be advisable just to read all variables in as 'character' colClasses = "character"
and then convert the specific columns to numeric once the csv is read in:
stuckey <- read.csv("C:/kalle/R/stuckey.csv", colClasses = "character")
point <- as.numeric(stuckey$PTS)
time <- as.numeric(stuckey$MP)
In your code snippet, you could also resolve this by providing an implementation for the __new__
method in the subclass, likewise:
def G(F):
def __new__(cls):
# do something here
But this is a hack and I advise you against it, unless you know what you are doing. For nearly all cases I advise you to use the abc
module, that others before me have suggested.
Also when you create a new (base) class, make it subclass object
, like this: class MyBaseClass(object):
. I don't know if it is that much significant anymore, but it helps retain style consistency on your code
I was Working with Elastic SQL plugin. Query is done with GET method using cURL as below:
curl -XGET http://localhost:9200/_sql/_explain -H 'Content-Type: application/json' \
-d 'SELECT city.keyword as city FROM routes group by city.keyword order by city'
I exposed a custom port at public server, doing a reverse proxy with Basic Auth set.
This code, works fine plus Basic Auth Header:
$host = 'http://myhost.com:9200';
$uri = "/_sql/_explain";
$auth = "john:doe";
$data = "SELECT city.keyword as city FROM routes group by city.keyword order by city";
function restCurl($host, $uri, $data = null, $auth = null, $method = 'DELETE'){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $host.$uri);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $method);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
if ($method == 'POST')
curl_setopt($ch, CURLOPT_POST, 1);
if ($auth)
curl_setopt($ch, CURLOPT_USERPWD, $auth);
if (strlen($data) > 0)
curl_setopt($ch, CURLOPT_POSTFIELDS,$data);
$resp = curl_exec($ch);
if(!$resp){
$resp = (json_encode(array(array("error" => curl_error($ch), "code" => curl_errno($ch)))));
}
curl_close($ch);
return $resp;
}
$resp = restCurl($host, $uri); //DELETE
$resp = restCurl($host, $uri, $data, $auth, 'GET'); //GET
$resp = restCurl($host, $uri, $data, $auth, 'POST'); //POST
$resp = restCurl($host, $uri, $data, $auth, 'PUT'); //PUT
Your variable declarations and their scope are correct. The problem you are facing is that the first AJAX request may take a little bit time to finish. Therefore, the second URL will be filled with the value of sID
before the its content has been set. You have to remember that AJAX request are normally asynchronous, i.e. the code execution goes on while the data is being fetched in the background.
You have to nest the requests:
$.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.1/summoner/by-name/"+input+"?api_key=API_KEY_HERE" , function(name){ obj = name; // sID is only now available! sID = obj.id; console.log(sID); });
name.id
is sufficient unless you really need the other variables outside the function.$.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.1/summoner/by-name/"+input+"?api_key=API_KEY_HERE" , function(name){ // We don't need sID or obj here - name.id is sufficient console.log(name.id); doSecondRequest(name.id); }); /// TODO Choose a better name function doSecondRequest(sID) { $.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.2/stats/by-summoner/" + sID + "/summary?api_key=API_KEY_HERE", function(stats){ console.log(stats); }); }
Hapy New Year :)
I use the AbsoluteUri and you can get it like this:
string myURI = Request.Url.AbsoluteUri;
if (!WebSecurity.IsAuthenticated) {
Response.Redirect("~/Login?returnUrl="
+ Request.Url.AbsoluteUri );
Then after you login:
var returnUrl = Request.QueryString["returnUrl"];
if(WebSecurity.Login(username,password,true)){
Context.RedirectLocal(returnUrl);
It works well for me.
Try this
using (Image image = Image.FromFile(Path))
{
using (MemoryStream m = new MemoryStream())
{
image.Save(m, image.RawFormat);
byte[] imageBytes = m.ToArray();
// Convert byte[] to Base64 String
string base64String = Convert.ToBase64String(imageBytes);
return base64String;
}
}
You can actually just use the Remove overload that takes one parameter:
str = str.Remove(str.Length - 3);
However, if you're trying to avoid hard coding the length, you can use:
str = str.Remove(str.IndexOf(','));
There is obviously another process listening on the port. You might find out that process by using the following command:
$ lsof -i :8000
or change your tornado app's port. tornado's error info not Explicitly on this.
I can't get that constructor to work either. This however seems to work:
# $temp = Get-ResourceFiles
$resourceFiles = New-Object System.Collections.ArrayList($null)
$resourceFiles.AddRange($temp)
You can also pass an integer in the constructor to set an initial capacity.
What do you mean when you say you want to enumerate the files? Why can't you just filter the wanted values into a fresh array?
Edit:
It seems that you can use the array constructor like this:
$resourceFiles = New-Object System.Collections.ArrayList(,$someArray)
Note the comma. I believe what is happening is that when you call a .NET method, you always pass parameters as an array. PowerShell unpacks that array and passes it to the method as separate parameters. In this case, we don't want PowerShell to unpack the array; we want to pass the array as a single unit. Now, the comma operator creates arrays. So PowerShell unpacks the array, then we create the array again with the comma operator. I think that is what is going on.
I know this is an old question and the answers provided work fine ... but this is a bit shorter and doesn't require any additional libraries ( i.e. JSON ):
function arraysAreEqual(ary1,ary2){
return (ary1.join('') == ary2.join(''));
}

For Ionic users, I had hell with this because .toISOString()
has to be used with the html template.
This will grab the current date, but of course can be added to previous answers for a selected date.
I got it fixed using this:
date = new Date();_x000D_
public currentDate: any = new Date(this.date.getTime() - this.date.getTimezoneOffset()*60000).toISOString();
_x000D_
The *60000 is indicating the UTC -6 which is CST so whatever TimeZone is needed, the number and difference can be changed.
i know this was posted long time back, i would like to share how i solved it.
since i have my office laptop ( VPN and proxy was configured ).
i checked the environment variable NO_PROXY
> echo %NO_PROXY%
it returned with empty values
now i have set the NO_PROXY with localhost and 127.0.0.1
> set NO_PROXY=127.0.0.1,localhost
if you want to append to existing values, then
> set NO_PROXY=%NO_PROXY%,127.0.0.1,localhost
after this , i have restarted zookeeper and kafka
worked like a charm

You should not use those headers, the headers determine what kind of type you are sending, and you are clearly sending an object, which means, JSON.
Instead you should set the option responseType
to text
:
addToCart(productId: number, quantity: number): Observable<any> {
const headers = new HttpHeaders().set('Content-Type', 'text/plain; charset=utf-8');
return this.http.post(
'http://localhost:8080/order/addtocart',
{ dealerId: 13, createdBy: "-1", productId, quantity },
{ headers, responseType: 'text'}
).pipe(catchError(this.errorHandlerService.handleError));
}
In an Object Oriented parking lot, there will be no need for attendants because the cars will "know how to park".
Finding a usable car on the lot will be difficult; the most common models will either have all their moving parts exposed as public member variables, or they will be "fully encapsulated" cars with no windows or doors.
The parking spaces in our OO parking lot will not match the size and shape of the cars (an "impediance mismatch" between the spaces and the cars)
License tags on our lot will have a dot between each letter and digit. Handicaped parking will only be available for licenses beginning with "_", and licenses beginning with "m_" will be towed.
I found the console output of my job in the browser at the following location:
http://[Jenkins URL]/job/[Job Name]/default/[Build Number]/console
Answer provided by user mgaert works for me. I think it should be marked as the right answer.
It works also with complex selectors like in this example:
<!--
selects only direct subdirectories of ${targetdir} if they have a
sub-subdirectory named either sub1 or sub2
-->
<dirset dir="${targetdir}" >
<and>
<depth max="0"/>
<or>
<present targetdir="${targetdir}">
<globmapper from="*" to="*/sub1" />
</present>
<present targetdir="${targetdir}">
<globmapper from="*" to="*/sub2" />
</present>
</or>
</and>
</dirset>
Thus, having a directory structure like this:
targetdir
+-- bar
¦ +-- sub3
+-- baz
¦ +-- sub1
+-- foo
¦ +-- sub2
+-- phoo
¦ +-- sub1
¦ +-- sub2
+-- qux
+-- xyzzy
+-- sub1
the above dirset would contain only
baz foo phoo(
bar
doesn't match because of sub3 while xyzzy
doesn't match because it's not a direct subdirectory of targetdir
)
The documentation reiterates your findings here: https://github.com/angular-ui/ui-router/wiki/URL-Routing#stateparams-service
If my memory serves, $stateParams
was introduced later than the original $state.params
, and seems to be a simple helper injector to avoid continuously writing $state.params
.
I doubt there are any best practice guidelines, but context wins out for me. If you simply want access to the params received into the url, then use $stateParams
. If you want to know something more complex about the state itself, use $state
.
I'm not sure what you're trying to do, but here's something to consider: c();
won't do anything. c
is an instance of the class checkbox
and not a method to be called. So consider this:
public class FirstWindow extends JFrame { public FirstWindow() { checkbox c = new checkbox(); c.yourMethod(yourParameters); // call the method you made in checkbox } } public class checkbox extends JFrame { public checkbox(yourParameters) { // this is the constructor method used to initialize instance variables } public void yourMethod() // doesn't have to be void { // put your code here } }
Some process is using the port 443, so you can change the port that is used by xampp, to be able to use it. For this job you have to do this:
1- Open httpd-ssl.conf in xampp\apache\conf\extra
2- Look for the line containing Listen 443
3- Change port number to anything you want. I use 4430. ex. Listen 4430.
4- Replace every 443 strings in that file with 4430 and save the file.
<head>

import re
def RemoveInList(sub,LinSplitUnOr):
indices = [i for i, x in enumerate(LinSplitUnOr) if re.search(sub, x)]
A = [i for j, i in enumerate(LinSplitUnOr) if j not in indices]
return A
where sub
is a patter that you do not wish to have in a list of lines LinSplitUnOr
for example
A=['Apple.good','Orange.good','Pear.bad','Pear.good','Banana.bad','Potato.bad']
sub = 'good'
A=RemoveInList(sub,A)
Then A

Split your date into year, month, and day components then use Date:
var d = new Date(year, month, day);
d.setMonth(d.getMonth() + 8);
Date will take care of fixing the year.
Like this:
var myString = "19 51 2.108997";
var stringParts = myString.split(" ");
var html = "<span>" + stringParts[0] + " " + stringParts[1] + "</span> <span>" + stringParts[2] + "</span";
Many of these answers do work, but I have found the easiest way by far is to send data through ViewData or ViewBag and let JSON.Net serialize it.
I use this technique when Javascript is needed for HTML generation before the page load or when AJAX overhead needs to be avoided:
In the controller:
public ActionResult MyController()
{
var addresses = myAddressesGetter();
ViewData["addresses"] = addresses ;
return View();
}
In the view:
@section scripts {
<script type="text/javascript">
var MyjavascriptAddresses: @Html.Raw(JsonConvert.SerializeObject(ViewData["addresses"])),
</script>
}
You can always rely on JSON.NET whereas some browsers have poor JSON deserialization support.
Another benefit over some methods in that you can see the Javascript using your browser's View --> Source
, since it is simply text generated server-side.
Note that In most situations, Web API a more elegant way to get JSON to the client.
Make sure that your password doesn't have special characters and just keep a plain password (for ex: 12345), it will work. This is the strangest thing that I have ever seen. I spent about 2 hours to figure this out.
Note: 12345 mentioned below is your plain password
GRANT ALL PRIVILEGES ON dbname.* TO 'yourusername'@'%' IDENTIFIED BY '12345';
For example:
const std::map<LogLevel, const char*> g_log_levels_dsc =
{
{ LogLevel::Disabled, "[---]" },
{ LogLevel::Info, "[inf]" },
{ LogLevel::Warning, "[wrn]" },
{ LogLevel::Error, "[err]" },
{ LogLevel::Debug, "[dbg]" }
};
If map is a data member of a class, you can initialize it directly in header by the following way (since C++17):
// Example
template<>
class StringConverter<CacheMode> final
{
public:
static auto convert(CacheMode mode) -> const std::string&
{
// validate...
return s_modes.at(mode);
}
private:
static inline const std::map<CacheMode, std::string> s_modes =
{
{ CacheMode::All, "All" },
{ CacheMode::Selective, "Selective" },
{ CacheMode::None, "None" }
// etc
};
};
I solved this another way. Let's say you have your dependency.js
export const myFunction = () => { }
I create a depdency.mock.js file besides it with the following content:
export const mockFunction = jest.fn();
jest.mock('dependency.js', () => ({ myFunction: mockFunction }));
And in the test, before I import the file that has the dependency, I use:
import { mockFunction } from 'dependency.mock'
import functionThatCallsDep from './tested-code'
it('my test', () => {
mockFunction.returnValue(false);
functionThatCallsDep();
expect(mockFunction).toHaveBeenCalled();
})
It’s less confusing to always use an escaped hyphen, so that it doesn't have to be positionally dependent. That’s a \-
inside the bracketed character class.
But there’s something else to consider. Some of those enumerated characters should possibly be written differently. In some circumstances, they definitely should.
This comparison of regex flavors says that C? can use some of the simpler Unicode properties. If you’re dealing with Unicode, you should probably use the general category \p{L}
for all possible letters, and maybe \p{Nd}
for decimal numbers. Also, if you want to accomodate all that dash punctuation, not just HYPHEN-MINUS, you should use the \p{Pd}
property. You might also want to write that sequence of whitespace characters simply as \s
, assuming that’s not too general for you.
All together, that works out to apattern of [\p{L}\p{Nd}\p{Pd}!$*]
to match any one character from that set.
I’d likely use that anyway, even if I didn’t plan on dealing with the full Unicode set, because it’s a good habit to get into, and because these things often grow beyond their original parameters. Now when you lift it to use in other code, it will still work correctly. If you hard-code all the characters, it won’t.
How about something like this?
var pathArray = $('input[type=file]').val().split('\\');
alert(pathArray[pathArray.length - 1]);
Ive just been searching for a solution and come across Spreadsheetlight
which looks very promising. Its open source and available as a nuget package.
You can do this
On server.
global.io=require("socket.io")(server);
io.on("connection",function(client){
console.log("client is ",client.id);
//This is handle by current connected client
client.emit('messages',{hello:'world'})
//This is handle by every client
io.sockets.emit("data",{data:"This is handle by every client"})
app1.saveSession(client.id)
client.on("disconnect",function(){
app1.deleteSession(client.id)
console.log("client disconnected",client.id);
})
})
//And this is handle by particular client
var socketId=req.query.id
if(io.sockets.connected[socketId]!=null) {
io.sockets.connected[socketId].emit('particular User', {data: "Event response by particular user "});
}
And on client, it is very easy to handle.
var socket=io.connect("http://localhost:8080/")
socket.on("messages",function(data){
console.log("message is ",data);
//alert(data)
})
socket.on("data",function(data){
console.log("data is ",data);
//alert(data)
})
socket.on("particular User",function(data){
console.log("data from server ",data);
//alert(data)
})
In OSX, you can set the classpath from scratch like this:
export CLASSPATH=/path/to/some.jar:/path/to/some/other.jar
Or you can add to the existing classpath like this:
export CLASSPATH=$CLASSPATH:/path/to/some.jar:/path/to/some/other.jar
This is answering your exact question, I'm not saying it's the right or wrong thing to do; I'll leave that for others to comment upon.
Use .getMinutes()
to get the current minutes, then add 20 and use .setMinutes()
to update the date object.
var twentyMinutesLater = new Date();
twentyMinutesLater.setMinutes(twentyMinutesLater.getMinutes() + 20);
Simple example :
package test;
public class UpperClass {
public static class StaticInnerClass {}
public class InnerClass {}
public static void main(String[] args) {
// works
StaticInnerClass stat = new StaticInnerClass();
// doesn't compile
InnerClass inner = new InnerClass();
}
}
If non-static the class cannot be instantiated exept in an instance of the upper class (so not in the example where main is a static function)
Short answer: yes. You can do with this:
var myArray = ["element1", "element2", "element3", "element4"];
for (i = 0; i < myArray.length; i++) {
console.log(myArray[i]);
}
In a browser console, you can see something like "element1", "element2", etc., printed.
I don't like that much solutions based on multiplying text-shadows, it's not really flexible, it may work for a 2 pixels stroke where directions to add are 8, but with just 3 pixels stroke directions became 16, and so on... Not really confortable to manage.
The right tool exists, it's SVG <text>
The browsers' support problem worth nothing in this case, 'cause the usage of text-shadow has its own support problem too,
filter: progid:DXImageTransform
can be used or IE < 10 but often doesn't work as expected.
To me the best solution remains SVG with a fallback in not-stroked text for older browser:
This kind of approuch works on pratically all versions of Chrome and Firefox, Safari since version 3.04, Opera 8, IE 9
Compared to text-shadow
whose supports are:
Chrome 4.0,
FF 3.5,
IE 10,
Safari 4.0,
Opera 9, it results even more compatible.

Here's my slightly different approach to this, written as an excercise
function addOrChangeParameters( url, params )
{
let splitParams = {};
let splitPath = (/(.*)[?](.*)/).exec(url);
if ( splitPath && splitPath[2] )
splitPath[2].split("&").forEach( k => { let d = k.split("="); splitParams[d[0]] = d[1]; } );
let newParams = Object.assign( splitParams, params );
let finalParams = Object.keys(newParams).map( (a) => a+"="+newParams[a] ).join("&");
return splitPath ? (splitPath[1] + "?" + finalParams) : (url + "?" + finalParams);
}
usage:
const url = "http://testing.com/path?empty&value1=test&id=3";
addOrChangeParameters( url, {value1:1, empty:"empty", new:0} )
"http://testing.com/path?empty=empty&value1=1&id=3&new=0"
That is because you are only checking the current checkbox.
Change it to
function checkUncheck() {
$('.pChk').click(function() {
if ( $('.pChk:checked').length > 0) {
$("#ProjectListButton").show();
} else {
$("#ProjectListButton").hide();
}
});
}
to check if any of the checkboxes is checked (lots of checks in this line..).

If you do not want to install anything at all you can "build your own" batch file that does the job from standard Windows commands. Here are some pointers as to how to do it.
1) Using find /c /v "" yourinput.file, get the number of lines in your input file. The output is something like:
---------- T.TXT: 15
2) Using for /f, parse this output to get the number 15.
3) Using set /a, calculate the number of head lines that needs to be skipped
4) Using for /f "skip=n" skip the head lines and echo/process the tail lines.
If I find the time, I will build such a batch file and post it back here.
tail.bat
REM tail.bat
REM
REM Usage: tail.bat <file> <number-of-lines>
REM
REM Examples: tail.bat myfile.txt 10
REM tail.bat "C:\My File\With\Spaces.txt" 10
@ECHO OFF
for /f "tokens=2-3 delims=:" %%f in ('find /c /v "" %1') do (
for %%F in (%%f %%g) do set nbLines=%%F )
set /a nbSkippedLines=%nbLines%-%2
for /f "usebackq skip=%nbSkippedLines% delims=" %%d in (%1) do echo %%d
Use an input
event.
var button = $("#buttonId");
$("#textareaID").on('input',function(e){
if(e.target.value === ''){
// Textarea has no value
button.hide();
} else {
// Textarea has a value
button.show();
}
});
This might be impossible or at least very hard. The DLL's contents don't depend (a lot) on it being written in C++; it's all machine code. That code might have been optimized so a lot of information that was present in the original source code is simply gone.
That said, here is one article that goes through a lot of material about doing this.
You could set the @Input
on the setter directly, as described below:
_allowDay: boolean;
get allowDay(): boolean {
return this._allowDay;
}
@Input() set allowDay(value: boolean) {
this._allowDay = value;
this.updatePeriodTypes();
}
See this Plunkr: https://plnkr.co/edit/6miSutgTe9sfEMCb8N4p?p=preview.
You should build your own Authorize-filter attribute.
Here's mine to study ;)
Public Class RequiresRoleAttribute : Inherits ActionFilterAttribute
Private _role As String
Public Property Role() As String
Get
Return Me._role
End Get
Set(ByVal value As String)
Me._role = value
End Set
End Property
Public Overrides Sub OnActionExecuting(ByVal filterContext As System.Web.Mvc.ActionExecutingContext)
If Not String.IsNullOrEmpty(Me.Role) Then
If Not filterContext.HttpContext.User.Identity.IsAuthenticated Then
Dim redirectOnSuccess As String = filterContext.HttpContext.Request.Url.AbsolutePath
Dim redirectUrl As String = String.Format("?ReturnUrl={0}", redirectOnSuccess)
Dim loginUrl As String = FormsAuthentication.LoginUrl + redirectUrl
filterContext.HttpContext.Response.Redirect(loginUrl, True)
Else
Dim hasAccess As Boolean = filterContext.HttpContext.User.IsInRole(Me.Role)
If Not hasAccess Then
Throw New UnauthorizedAccessException("You don't have access to this page. Only " & Me.Role & " can view this page.")
End If
End If
Else
Throw New InvalidOperationException("No Role Specified")
End If
End Sub
End Class
Hmm, there are many solution written for php version lower than 7.1.
Here is an other simple one for those who doesn't want catch all exception and can't make common interfaces:
<?php
$ex = NULL
try {
/* ... */
} catch (FirstException $ex) {
// just do nothing here
} catch (SecondException $ex) {
// just do nothing here
}
if ($ex !== NULL) {
// handle those exceptions here!
}
?>
Here is how one can do it. I will give an example with joining so that it becomes super clear to someone.
$products = DB::table('products AS pr')
->leftJoin('product_families AS pf', 'pf.id', '=', 'pr.product_family_id')
->select('pr.id as id', 'pf.name as product_family_name', 'pf.id as product_family_id')
->orderBy('pr.id', 'desc')
->get();
Hope this helps.
In my case I was missing @ at the beginning of the foreach
@foreach (var item in Model)
{
<tr class="clickable-row">
<td class="clickable-field">
@Html.DisplayFor(modelItem => item.Label)
</td>
<td class="clickable-field hidden-xs">
@Html.DisplayFor(modelItem => item.Value)
</td>
</tr>
}
def removeNonAscii(s): return "".join(filter(lambda x: ord(x)<128, s))
edit: my first impulse is always to use a filter, but the generator expression is more memory efficient (and shorter)...
def removeNonAscii(s): return "".join(i for i in s if ord(i)<128)
Keep in mind that this is guaranteed to work with UTF-8 encoding (because all bytes in multi-byte characters have the highest bit set to 1).
Probably a bit late but this is worth a mention:
Environment.GetCommandLineArgs()[0];
Or more correctly to get just the directory path:
System.IO.Path.GetDirectoryName(Environment.GetCommandLineArgs()[0]);
Edit:
Quite a few people have pointed out that GetCommandLineArgs
is not guaranteed to return the program name. See The first word on the command line is the program name only by convention. The article does state that "Although extremely few Windows programs use this quirk (I am not aware of any myself)". So it is possible to 'spoof' GetCommandLineArgs
, but we are talking about a console application. Console apps are usually quick and dirty. So this fits in with my KISS philosophy.

After some fiddling with a script I came to this action. Copy and save it in a .bat file:
FOR /F "usebackq tokens=5" %%i IN (`netstat -aon ^| find "3306"`) DO taskkill /F /PID %%i
Change 'find "3306"' in the port number which needs to be free. Then run the file as administrator. It will kill all the processes running on this port.
I have a related issue which I solved and wanted to let folks know about my solution. Using SQL Developer I exported from one database to csv, then tried to import it into another database. I kept getting an error in my date fields. My date fields were in the Timestamp format:
28-JAN-11 03.25.11.000000000 PM
The above solution (changing the NLS preferences) did not work for me when I imported, but I finally got the following to work:
In the Import Wizard Column Definition screen, I entered "DD-MON-RR HH.MI.SSXFF AM
" in the Format box, and it finally imported successfully. Unfortunately I have dozens of date fields and to my knowledge there is no way to systematically apply this format to all date fields so I had to do it manually....sigh. If anyone knows a better way I'd be happy to hear it!

You might take a look at JavaScience's source for OpenSSLKey
There's code in there that does exactly what you want to do.
In fact, they have a lot of crypto source code available here.
Source code snippet:

public static RSACryptoServiceProvider DecodeRSAPrivateKey(byte[] privkey)
{
byte[] MODULUS, E, D, P, Q, DP, DQ, IQ ;
// --------- Set up stream to decode the asn.1 encoded RSA private key ------

This article helped me a lot in understanding the concept.
In summary,
Some good reading material: conditional probability , Joint PDF
clone()
method can be used for this purpose.With Spring 3.0 you can use the HttpEntity
return object. If you use this, then your controller does not need a HttpServletResponse
object, and therefore it is easier to test.
Except this, this answer is relative equals to the one of Infeligo.
If the return value of your pdf framework is an byte array (read the second part of my answer for other return values) :
@RequestMapping(value = "/files/{fileName}", method = RequestMethod.GET)
public HttpEntity<byte[]> createPdf(
@PathVariable("fileName") String fileName) throws IOException {
byte[] documentBody = this.pdfFramework.createPdf(filename);
HttpHeaders header = new HttpHeaders();
header.setContentType(MediaType.APPLICATION_PDF);
header.set(HttpHeaders.CONTENT_DISPOSITION,
"attachment; filename=" + fileName.replace(" ", "_"));
header.setContentLength(documentBody.length);
return new HttpEntity<byte[]>(documentBody, header);
}
If the return type of your PDF Framework (documentBbody
) is not already a byte array (and also no ByteArrayInputStream
) then it would been wise NOT to make it a byte array first. Instead it is better to use:
InputStreamResource
,PathResource
(since Spring 4.0) orFileSystemResource
, example with FileSystemResource
:
@RequestMapping(value = "/files/{fileName}", method = RequestMethod.GET)
public HttpEntity<byte[]> createPdf(
@PathVariable("fileName") String fileName) throws IOException {
File document = this.pdfFramework.createPdf(filename);
HttpHeaders header = new HttpHeaders();
header.setContentType(MediaType.APPLICATION_PDF);
header.set(HttpHeaders.CONTENT_DISPOSITION,
"attachment; filename=" + fileName.replace(" ", "_"));
header.setContentLength(document.length());
return new HttpEntity<byte[]>(new FileSystemResource(document),
header);
}
Path.GetFullPath(fileUpload.PostedFile.FileName);
Sorry this 'll get your program file directory + your file name.
I use the single line
(cd ${FILENAME%/*}; pwd)
However, this can only be used when $FILENAME
has a leading path of any kind (relative or absolute) that actually exists. If there is no leading path at all, then the answer is simply $PWD
. If the leading path does not exist, then the answer may be indeterminate, otherwise and the answer is simply ${FILENAME%/*}
if the path is absolute.
Putting this all together I would suggest using the following function
function abspath() {
# argument 1: file pathname (relative or absolute)
# returns: file pathname (absolute)
if [ "$1" == "${1##*/}" ]; then # no path at all
echo "$PWD"
elif [ "${1:0:1}" == "/" -a "${1/../}" == "$1" ]; then # strictly absolute path
echo "${1%/*}"
else # relative path (may fail if a needed folder is non-existent)
echo "$(cd ${1%/*}; pwd)"
fi
}
Note also that this only work in bash
and compatible shells. I don't believe the substitutions work in the simple shell sh
.
small_letters = map(chr, range(ord('a'), ord('z')+1))
big_letters = map(chr, range(ord('A'), ord('Z')+1))
digits = map(chr, range(ord('0'), ord('9')+1))
or
import string
string.letters
string.uppercase
string.digits
This solution uses the ASCII table. ord
gets the ascii value from a character and chr
vice versa.
>>> small_letters = map(chr, range(ord('a'), ord('z')+1))
>>> an = small_letters[0:(ord('n')-ord('a')+1)]
>>> print(" ".join(an))
a b c d e f g h i j k l m n
>>> print(" ".join(small_letters[0::2]))
a c e g i k m o q s u w y
>>> s = small_letters[0:(ord('n')-ord('a')+1):2]
>>> print(" ".join(s))
a c e g i k m
>>> urls = ["hello.com/", "hej.com/", "hallo.com/"]
>>> print([x + y for x, y in zip(urls, an)])
['hello.com/a', 'hej.com/b', 'hallo.com/c']
Yes, it's definitely possible, although I am struggling with the same issue at the moment. I've managed to get the cells to hide and everything works ok, but I cannot currently make the thing animate neatly. Here is what I have found:
I am hiding rows based on the state of an ON / OFF switch in the first row of the first section. If the switch is ON there is 1 row beneath it in the same section, otherwise there are 2 different rows.
I have a selector called when the switch is toggled, and I set a variable to indicate which state I am in. Then I call:
[[self tableView] reloadData];
I override the tableView:willDisplayCell:forRowAtIndexPath: function and if the cell is supposed to be hidden I do this:
[cell setHidden:YES];
That hides the cell and its contents, but does not remove the space it occupies.
To remove the space, override the tableView:heightForRowAtIndexPath: function and return 0 for rows that should be hidden.
You also need to override tableView:numberOfRowsInSection: and return the number of rows in that section. You have to do something strange here so that if your table is a grouped style the rounded corners occur on the correct cells. In my static table there is the full set of cells for the section, so there is the first cell containing the option, then 1 cell for the ON state options and 2 more cells for the OFF state options, a total of 4 cells. When the option is ON, I have to return 4, this includes the hidden option so that the last option displayed has a rounded box. When the option is off, the last two options are not displayed so I return 2. This all feels clunky. Sorry if this isn't very clear, its tricky to describe. Just to illustrate the setup, this is the construction of the table section in IB:
So when the option is ON the table reports two rows which are:
When the option is OFF the table reports four rows which are:
This approach doesn't feel correct for several reasons, its just as far as I have got with my experimentation so far, so please let me know if you find a better way. The problems I have observed so far are:
It feels wrong to be telling the table the number of rows is different to what is presumably contained in the underlying data.
I can't seem to animate the change. I've tried using tableView:reloadSections:withRowAnimation: instead of reloadData and the results don't seem to make sense, I'm still trying to get this working. Currently what seems to happen is the tableView does not update the correct rows so one remains hidden that should be displayed and a void is left under the first row. I think this might be related to the first point about the underlying data.
Hopefully someone will be able to suggest alternative methods or perhaps how to extend with animation, but maybe this will get you started. My apologies for the lack of hyperlinks to functions, I put them in but they were rejected by the spam filter because I am a fairly new user.
I think you want something like the following.

Your .flex-item
elements should be block level (div
instead of span
) if you want the height and top/bottom padding to work properly.
Also, on .row
, set the width to auto
instead of 100%
.
Your .flex-container
properties are fine.
If you want the .row
to be centered vertically in the view port, assign 100% height to html
and body
, and also zero out the body
margins.
Note that .flex-container
needs a height to see the vertical alignment effect, otherwise, the container computes the minimum height needed to enclose the content, which is less than the view port height in this example.
Footnote:
The flex-flow
, flex-direction
, flex-wrap
properties could have made this design easier to implement. I think that the .row
container is not needed unless you want to add some styling around the elements (background image, borders and so on).
A useful resource is: http://demo.agektmr.com/flexbox/

You can write a special heap allocator for specific sizes of objects that is very performant. However, the general heap allocator is not particularly performant.
Also I agree with Torbjörn Gyllebring about the expected lifetime of objects. Good point!
You can use a link to invoke history.go(-1)
in Javascript, which is essentially equivalent to clicking the Back button. Ideally, however, it'd be better to just create a link back to the URL from whence the user was posted to the form - that way the proper "flow" of history is preserved and the user doesn't wonder why they have something to click "Forward" to which is actually just submitting the form again.
Check if this port is open. Maybe your SSH demon is not running. See if sshd is running. If not, then start it.
2014 answer: classList.toggle()
is the standard and supported by most browsers.
Older browsers can use use classlist.js for classList.toggle():
var menu = document.querySelector('.menu') // Using a class instead, see note below.
menu.classList.toggle('hidden-phone');
As an aside, you shouldn't be using IDs (they leak globals into the JS window
object).
Try this:
<li onclick="myfunction(this)">
function myfunction(li) {
var TextInsideLi = li.getElementsByTagName('p')[0].innerHTML;
}
I also had the same problem. I added the following. It works for me
Microsoft.EntityFrameworkCore.SqlServer
All those settings are necessary to choose which tags you are interested in, but in order to display these tags in a list, you also need to select the right Eclipse perspective. I finally discovered that the "Markers" tab containing the "Task" list is only available under the "Java EE" perspective... Hope this helps! :-)
Assuming your page is available under "http://example.com"
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
driver = webdriver.Firefox()
driver.get("http://example.com")
Select element by id:
inputElement = driver.find_element_by_id("a1")
inputElement.send_keys('1')
Now you can simulate hitting ENTER:
inputElement.send_keys(Keys.ENTER)
or if it is a form you can submit:
inputElement.submit()
This is the better solution:
verify(mock_contractsDao, times(1)).save(Mockito.eq("Parameter I'm expecting"));
Run this in the command line:
php -r "echo php_ini_loaded_file().PHP_EOL;"
spool "D:\test\test.txt"
select
a.ename
from
employee a
inner join department b
on
(
a.dept_id = b.dept_id
)
;
spool off
This query will spool the sql result in D:\test\test.txt
There's a lot of typedef
going on here. Personally I'm against "hiding the asterisk", i.e. typedef
:ing pointer types into something that doesn't look like a pointer. In C, pointers are quite important and really affect the code, there's a lot of difference between foo
and foo *
.
Many of the answers are also confused about this, I think.
Your allocation of an array of Chess
values, which are pointers to values of type chess
(again, a very confusing nomenclature that I really can't recommend) should be like this:
Chess *array = malloc(n * sizeof *array);
Then, you need to initialize the actual instances, by looping:
for(i = 0; i < n; ++i)
array[i] = NULL;
This assumes you don't want to allocate any memory for the instances, you just want an array of pointers with all pointers initially pointing at nothing.
If you wanted to allocate space, the simplest form would be:
for(i = 0; i < n; ++i)
array[i] = malloc(sizeof *array[i]);
See how the sizeof
usage is 100% consistent, and never starts to mention explicit types. Use the type information inherent in your variables, and let the compiler worry about which type is which. Don't repeat yourself.
Of course, the above does a needlessly large amount of calls to malloc()
; depending on usage patterns it might be possible to do all of the above with just one call to malloc()
, after computing the total size needed. Then you'd still need to go through and initialize the array[i]
pointers to point into the large block, of course.
I personally prefer the simpler syntax of the ~ operator.
SELECT id FROM TAG_TABLE WHERE 'aaaaaaaa' ~ tag_name;
Worth reading through Difference between LIKE and ~ in Postgres to understand the difference. `
Alternative solutions can be helpful...
You can also add a null character to the end of your lines using Perl, then use the -0
option in xargs. Unlike the xargs -d '\n' (in approved answer) - this works everywhere, including OS X.
For example, to recursively list (execute, move, etc.) MPEG3 files which may contain spaces or other funny characters - I'd use:
find . | grep \.mp3 | perl -ne 'chop; print "$_\0"' | xargs -0 ls
(Note: For filtering, I prefer the easier-to-remember "| grep" syntax to "find's" --name arguments.)
We use an EventHook as suggested from Michael Foord in his Event Pattern:
Just add EventHooks to your classes with:
class MyBroadcaster()
def __init__():
self.onChange = EventHook()
theBroadcaster = MyBroadcaster()
# add a listener to the event
theBroadcaster.onChange += myFunction
# remove listener from the event
theBroadcaster.onChange -= myFunction
# fire event
theBroadcaster.onChange.fire()
We add the functionality to remove all listener from an object to Michaels class and ended up with this:
class EventHook(object):
def __init__(self):
self.__handlers = []
def __iadd__(self, handler):
self.__handlers.append(handler)
return self
def __isub__(self, handler):
self.__handlers.remove(handler)
return self
def fire(self, *args, **keywargs):
for handler in self.__handlers:
handler(*args, **keywargs)
def clearObjectHandlers(self, inObject):
for theHandler in self.__handlers:
if theHandler.im_self == inObject:
self -= theHandler
Use test.md
as a example:
? spark-1.6.1 cat test.md
This is the first line;
This is the second line;
This is the last line.
scala> val textFile = sc.textFile("test.md")
scala> textFile.map(line => line.split(" ")).count()
res2: Long = 3
scala> textFile.flatMap(line => line.split(" ")).count()
res3: Long = 15
scala> textFile.map(line => line.split(" ")).collect()
res0: Array[Array[String]] = Array(Array(This, is, the, first, line;), Array(This, is, the, second, line;), Array(This, is, the, last, line.))
scala> textFile.flatMap(line => line.split(" ")).collect()
res1: Array[String] = Array(This, is, the, first, line;, This, is, the, second, line;, This, is, the, last, line.)
If you use map
method, you will get the lines of test.md
, for flatMap
method, you will get the number of words.
The map
method is similar to flatMap
, they are all return a new RDD. map
method often to use return a new RDD, flatMap
method often to use split words.
Something like:
>>> bytes.fromhex('4a4b4c').decode('utf-8')
'JKL'
Just put the actual encoding you are using.
Not that I know of, in pure C++. But a little modification of what you mentioned
string s = string(itoa(a));
should work, and it's pretty short.
Suggestions:
for example,
type
functionname( arguments )
{
if (something)
{
do stuff
}
else
{
do other stuff
}
switch (value)
{
case 'a':
astuff
break;
case 'b':
bstuff
//fallthrough //always comment fallthrough as intentional
case 'c':
break;
default: //always consider default, and handle it explicitly
break;
}
while ( the lights are on )
{
if ( something happened )
{
run around in circles
if ( you are scared ) //yeah, much more than 3-4 levels of indent are too many!
{
scream and shout
}
}
}
return typevalue; //always return something, you'll thank me later
}
Rather than
gb.get_group('foo')
I prefer using gb.groups
df.loc[gb.groups['foo']]
Because in this way you can choose multiple columns as well. for example:
df.loc[gb.groups['foo'],('A','B')]
Here's a simpler version in python. It does use only two pointers slow
& fast
def reverseList(head: ListNode) -> ListNode:
slow = None
fast = head
while fast:
node_next = fast.next
fast.next = slow
slow = fast
fast = node_next
return slow

I think that installation of Windows Driver Development Kit is quite a lengthy process, so I've included the declarations one needs to use DeviceIoControl
for this task.
If you have
<div>
<input type="checkbox" class="check-with-label" id="idinput" />
<label class="label-for-check" for="idinput">My Label</label>
</div>
you can do
.check-with-label:checked + .label-for-check {
font-weight: bold;
}
See this working. Note that this won't work in non-modern browsers.
You can find a list of formatting escapes on this page.
%d
is a signed integer, while %u
is an unsigned integer. Pointers (when treated as numbers) are usually non-negative.
If you actually want to display a pointer, use the %p
format specifier.
Just install this package and your code will work:=> Install-Package Microsoft.Owin.Host.SystemWeb -Version 2.1.0
json_encode() function will help you to encode array to JSON in php.
if you will use just json_encode function directly without any specific option, it will return an array. Like mention above question
$array = array(
2 => array("Afghanistan",32,13),
4 => array("Albania",32,12)
);
$out = array_values($array);
json_encode($out);
// [["Afghanistan",32,13],["Albania",32,12]]
Since you are trying to convert Array to JSON, Then I would suggest to use JSON_FORCE_OBJECT as additional option(parameters) in json_encode, Like below
<?php
$array=['apple','orange','banana','strawberry'];
echo json_encode($array, JSON_FORCE_OBJECT);
// {"0":"apple","1":"orange","2":"banana","3":"strawberry"}
?>

NSUInteger bytesPerPixel = 4;
NSUInteger bytesPerRow = bytesPerPixel * width;

Save below in a test.bat
and It'll work for you:
@echo off
net use Z: \\server\SharedFolderName password /user:domain\Username /persistent:yes
/persistent:yes
flag will tell the computer to automatically reconnect this share on logon. Otherwise, you need to run the script again during each boot to map the drive.

occurs when creating a docker image from base image eg. scratch
. This is because the resulting image does not have a shell to execute the image. If your use:
ENV EXECUTABLE hello
cmd [$EXECUTABLE]
in your docker file, docker uses /bin/sh to parse the input string. and hence the error. Inspecting on the image, your will find:
$docker inspect <image-name>
"Entrypoint": [
"/bin/sh",
"-c",
"[$HM_APP]"
]
This means that the ENTRYPOINT or CMD arguments will be parsed using /bin/sh -c. The solution that worked for me is to parse the command as a JSON array of string e.g.
cmd ["hello"]
and inspecting the image again:
"Entrypoint": [
"hello"
]
This removes the dependence on /bin/sh the docker app can now execute the binary file. Example:
FROM scratch
# Environmental variables
# Copy files
ADD . /
# Home dir
WORKDIR /bin
EXPOSE 8083
ENTRYPOINT ["hospitalms"]
Hope this helps someone in future.
Following code to return data in the json format ,instead of the xml -Web API 2 :-
Put following line in the Global.asax file
GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore;
GlobalConfiguration.Configuration.Formatters.Remove(GlobalConfiguration.Configuration.Formatters.XmlFormatter);
This can be done for a normal subview
inside a larger UIView
, but it doesn't work automatically for headerViews
. The height of a headerView
is determined by what's returned by tableView:heightForHeaderInSection:
so you have to calculate the height
based on the height
of the UILabel
plus space for the UIButton
and any padding
you need. You need to do something like this:
-(CGFloat)tableView:(UITableView *)tableView
heightForHeaderInSection:(NSInteger)section {
NSString *s = self.headeString[indexPath.section];
CGSize size = [s sizeWithFont:[UIFont systemFontOfSize:17]
constrainedToSize:CGSizeMake(281, CGFLOAT_MAX)
lineBreakMode:NSLineBreakByWordWrapping];
return size.height + 60;
}
Here headerString
is whatever string you want to populate the UILabel
, and the 281 number is the width
of the UILabel
(as setup in Interface Builder
)
Although i completely like Marco's Answer i think it is fair to point out that you can also use a publish/subscribe based framework to achieve the same result for example if you go with the event bus you can do the following
fragment :
EventBus.getDefault().post(new DoSomeActionEvent());
Activity:
@Subscribe
onSomeActionEventRecieved(DoSomeActionEvent doSomeActionEvent){
//Do something
}
Its a new operator for combined comparison. Similar to strcmp()
or version_compare() in behavior, but it can be used on all generic PHP values with the same semantics as <
, <=
, ==
, >=
, >
. It returns 0
if both operands are equal, 1
if the left is greater, and -1
if the right is greater. It uses exactly the same comparison rules as used by our existing comparison operators: <
, <=
, ==
, >=
and >
.
dropdowns always show up on top, only solution for this problem is to hide dropdowns when image is displayed (display:block or visibility:visibile) and show them when image hidden (display:none or visibility:hidden)
There is HTML and URI encodings. &
is &
encoded in HTML while %26
is &
in URI encoding.
So before URI encoding your string you might want to HTML decode and then URI encode it :)
var div = document.createElement('div');
div.innerHTML = '&AndOtherHTMLEncodedStuff';
var htmlDecoded = div.firstChild.nodeValue;
var urlEncoded = encodeURIComponent(htmlDecoded);
result %26AndOtherHTMLEncodedStuff
Hope this saves you some time
Actually, we use static properties and methods in a class, when we want to use some part of our program should exists there until our program is running. And we know that, to manipulate static properties, we need static methods as they are not a part of instance variable. And without static methods, to manipulate static properties is time consuming.
Can't test it right now, but:
select * from tablename where date >= dateadd(day, datediff(day, 1, getdate()), 0) and date < dateadd(day, datediff(day, 0, getdate()), 0)
Here is a complete example
#include <thread>
#include <iostream>
class Wrapper {
public:
void member1() {
std::cout << "i am member1" << std::endl;
}
void member2(const char *arg1, unsigned arg2) {
std::cout << "i am member2 and my first arg is (" << arg1 << ") and second arg is (" << arg2 << ")" << std::endl;
}
std::thread member1Thread() {
return std::thread([=] { member1(); });
}
std::thread member2Thread(const char *arg1, unsigned arg2) {
return std::thread([=] { member2(arg1, arg2); });
}
};
int main(int argc, char **argv) {
Wrapper *w = new Wrapper();
std::thread tw1 = w->member1Thread();
std::thread tw2 = w->member2Thread("hello", 100);
tw1.join();
tw2.join();
return 0;
}
Compiling with g++ produces the following result
g++ -Wall -std=c++11 hello.cc -o hello -pthread
i am member1
i am member2 and my first arg is (hello) and second arg is (100)
If your compiler supports (at least part of) C++11 you could do something like:
for (auto& t : myMap)
std::cout << t.first << " "
<< t.second.first << " "
<< t.second.second << "\n";
For C++03 I'd use std::copy
with an insertion operator instead:
typedef std::pair<string, std::pair<string, string> > T;
std::ostream &operator<<(std::ostream &os, T const &t) {
return os << t.first << " " << t.second.first << " " << t.second.second;
}
// ...
std:copy(myMap.begin(), myMap.end(), std::ostream_iterator<T>(std::cout, "\n"));

Install pika package as follows
$ sudo pip install pika==0.9.8
The installation depends on pip and git-core packages, you may need to install them first.
On Ubuntu:
$ sudo apt-get install python-pip git-core
On Debian:
$ sudo apt-get install python-setuptools git-core
$ sudo easy_install pip
On Windows: To install easy_install, run the MS Windows Installer for setuptools
> easy_install pip

You'll have to do 2 things to make a Bootstrap label (or anything really) adjust sizes based on screen size:
.label { font-size: 75% }
. So any extra selector on your CSS rule will make it more specific.Here's an example CSS listing to accomplish what you are asking, using the default 4 sizes in Bootstrap:
@media (max-width: 767) {
/* your custom css class on a parent will increase specificity */
/* so this rule will override Bootstrap's font size setting */
.autosized .label { font-size: 14px; }
}
@media (min-width: 768px) and (max-width: 991px) {
.autosized .label { font-size: 16px; }
}
@media (min-width: 992px) and (max-width: 1199px) {
.autosized .label { font-size: 18px; }
}
@media (min-width: 1200px) {
.autosized .label { font-size: 20px; }
}
Here is how it could be used in the HTML:
<!-- any ancestor could be set to autosized -->
<div class="autosized">
...
...
<span class="label label-primary">Label 1</span>
</div>
Your HTML and the way you call the function from the button look correct.
The problem appears to be in the CapacityCount
function. I'm getting this error in my console on Firefox 3.5: "document.all is undefined" on line 759 of bendelcorp.js.
Edit:
Looks like document.all
is an IE-only thing and is a nonstandard way of accessing the DOM. If you use document.getElementById()
, it should probably work. Example: document.getElementById("RUnits").value
instead of document.all.Capacity.RUnits.value
I found this subject researching. There is a way to copy all this data to an Excel Datasheet. (I have this problem before with a 50 million line CSV file) If there is any format, additional code could be included. Try this.
Sub ReadCSVFiles()
Dim i, j As Double
Dim UserFileName As String
Dim strTextLine As String
Dim iFile As Integer: iFile = FreeFile
UserFileName = Application.GetOpenFilename
Open UserFileName For Input As #iFile
i = 1
j = 1
Check = False
Do Until EOF(1)
Line Input #1, strTextLine
If i >= 1048576 Then
i = 1
j = j + 1
Else
Sheets(1).Cells(i, j) = strTextLine
i = i + 1
End If
Loop
Close #iFile
End Sub

I was able to get a combination of some of the other suggestions here working for me, but only while toggling the plt.interactive(False)
to True
and back again.
plt.interactive(True)
plt.pyplot.show()
This will flash up the my plots. Then setting to False
allowed for viewing.
plt.interactive(False)
plt.pyplot.show()

You can use the button :
1 - make the text empty
2 - set the background for it
+3 - you can use the selector to more useful and nice button
About the imagebutton you can set the image source and the background the same picture and it must be (*.png) when you do it you can make any design for the button
and for more beauty button use the selector //just Google it ;)
if (mysql_query("INSERT INTO PEOPLE (NAME ) VALUES ('COLE')")or die(mysql_error())) {
echo 'Success';
} else {
echo 'Fail';
}
Although since you have or die(mysql_error())
it will show the mysql_error() on the screen when it fails. You should probably remove that if it isnt the desired result
You could create an extension method to add all property values through reflection:
public static DataSet ToDataSet<T>(this IList<T> list)
{
Type elementType = typeof(T);
DataSet ds = new DataSet();
DataTable t = new DataTable();
ds.Tables.Add(t);
//add a column to table for each public property on T
foreach(var propInfo in elementType.GetProperties())
{
t.Columns.Add(propInfo.Name, propInfo.PropertyType);
}
//go through each property on T and add each value to the table
foreach(T item in list)
{
DataRow row = t.NewRow();
foreach(var propInfo in elementType.GetProperties())
{
row[propInfo.Name] = propInfo.GetValue(item, null);
}
}
return ds;
}
Considering that we have Set<String> stringSet
we can use following:
List<String> strList = new ArrayList<>(stringSet);
List<String> strList = Lists.newArrayList(stringSet);
List<String> strList = new ArrayList<>();
CollectionUtils.addAll(strList, stringSet);
List<String> strList = List.copyOf(stringSet);
List<String> strList = stringSet.stream().collect(Collectors.toUnmodifiableList());
import static java.util.stream.Collectors.*;
List<String> stringList1 = stringSet.stream().collect(toList());
As per the doc for the method toList()
There are no guarantees on the type, mutability, serializability, or thread-safety of the List returned; if more control over the returned List is required, use toCollection(Supplier).
So if we need a specific implementation e.g. ArrayList
we can get it this way:
List<String> stringList2 = stringSet.stream().
collect(toCollection(ArrayList::new));
We can make use of Collections::unmodifiableList
method and wrap the list returned in previous examples. We can also write our own custom method as:
class ImmutableCollector {
public static <T> Collector<T, List<T>, List<T>> toImmutableList(Supplier<List<T>> supplier) {
return Collector.of( supplier, List::add, (left, right) -> {
left.addAll(right);
return left;
}, Collections::unmodifiableList);
}
}
And then use it as:
List<String> stringList3 = stringSet.stream()
.collect(ImmutableCollector.toImmutableList(ArrayList::new));
Another possibility is to make use of collectingAndThen
method which allows some final transformation to be done before returning result:
List<String> stringList4 = stringSet.stream().collect(collectingAndThen(
toCollection(ArrayList::new),Collections::unmodifiableList));
One point to note is that the method Collections::unmodifiableList
returns an unmodifiable view of the specified list, as per doc. An unmodifiable view collection is a collection that is unmodifiable and is also a view onto a backing collection. Note that changes to the backing collection might still be possible, and if they occur, they are visible through the unmodifiable view. But the collector method Collectors.unmodifiableList
returns truly immutable list in Java 10.
$(...)[index] // gives you the DOM element at index
$(...).get(index) // gives you the DOM element at index
$(...).eq(index) // gives you the jQuery object of element at index
DOM objects don't have css
function, use the last...
$('ul li').eq(index).css({'background-color':'#343434'});
docs:
.get(index)
Returns: Element
.eq(index)
Returns: jQuery
There are 2 jQuery functions that you'll want to use here.
1) click
. This will take an anonymous function as it's sole parameter, and will execute it when the element is clicked.
2) html
. This will take an html string as it's sole parameter, and will replace the contents of your element with the html provided.
So, in your case, you'll want to do the following:
$('#content-container a').click(function(e){
$(this).parent().html('<a href="#">I\'m a new link</a>');
e.preventDefault();
});
If you only want to add content to your div, rather than replacing everything in it, you should use append
:
$('#content-container a').click(function(e){
$(this).parent().append('<a href="#">I\'m a new link</a>');
e.preventDefault();
});
If you want the new added links to also add new content when clicked, you should use event delegation:
$('#content-container').on('click', 'a', function(e){
$(this).parent().append('<a href="#">I\'m a new link</a>');
e.preventDefault();
});
SELECT text
FROM all_source
where name = 'FGETALGOGROUPKEY'
order by line
alternatively:
select dbms_metadata.get_ddl('FUNCTION', 'FGETALGOGROUPKEY')
from dual;
There is no block comment in VB.NET.
You need to use a '
in front of every line you want to comment out.
In Visual Studio you can use the keyboard shortcuts that will comment/uncomment the selected lines for you:
Ctrl + K, C to comment
Ctrl + K, U to uncomment
Ultimately, this is completely platform-dependent. Unicode-support is, unfortunately, very poor in Standard C++. For GCC, you will have to make it a narrow string, as they use UTF-8, and Windows wants a wide string, and you must output to wcout
.
// GCC
std::cout << "?";
// Windoze
wcout << L"?";
There is no portable way to read raw characters from a Java console.
Some platform-dependent workarounds have been presented above. But to be really portable, you'd have to abandon console mode and use a windowing mode, e.g. AWT or Swing.
Why not simply try this:
var promise = $http.get(url, {
params: query
}).then(function(response) {
console.log('Content-Range: ' + response.headers('Content-Range'));
return response.data;
});
Especially if you want to return the promise
so it could be a part of a promises chain.
You can check /etc/ld.so.preload file content
I fix it by:
echo "" > /etc/ld.so.preload
foreach ($Contents as $index=>$item) {
$item[$index];// if there are 15 $item[number] in this foreach, I want get the value : 15
}
Sign-off is a line at the end of the commit message which certifies who is the author of the commit. Its main purpose is to improve tracking of who did what, especially with patches.
Example commit:
Add tests for the payment processor.
Signed-off-by: Humpty Dumpty <[email protected]>
It should contain the user real name if used for an open-source project.
If branch maintainer need to slightly modify patches in order to merge them, he could ask the submitter to rediff, but it would be counter-productive. He can adjust the code and put his sign-off at the end so the original author still gets credit for the patch.
