Your code doesn't get the UTF-8 into memory as you read it back into a string again, so its no longer in UTF-8, but back in UTF-16 (though ideally its best to consider strings at a higher level than any encoding, except when forced to do so).
To get the actual UTF-8 octets you could use:
var serializer = new XmlSerializer(typeof(SomeSerializableObject));
var memoryStream = new MemoryStream();
var streamWriter = new StreamWriter(memoryStream, System.Text.Encoding.UTF8);
serializer.Serialize(streamWriter, entry);
byte[] utf8EncodedXml = memoryStream.ToArray();
I've left out the same disposal you've left. I slightly favour the following (with normal disposal left in):
var serializer = new XmlSerializer(typeof(SomeSerializableObject));
using(var memStm = new MemoryStream())
using(var xw = XmlWriter.Create(memStm))
{
serializer.Serialize(xw, entry);
var utf8 = memStm.ToArray();
}
Which is much the same amount of complexity, but does show that at every stage there is a reasonable choice to do something else, the most pressing of which is to serialise to somewhere other than to memory, such as to a file, TCP/IP stream, database, etc. All in all, it's not really that verbose.
I managed to get this working. The trick is to calculate: (a) current div user scroll position and (b) div scroll height, both BEFORE appending the new element.
If a === b, we know the user is at the bottom before appending the new element.
let div = document.querySelector('div.scrollableBox');
let span = document.createElement('span');
span.textContent = 'Hello';
let divCurrentUserScrollPosition = div.scrollTop + div.offsetHeight;
let divScrollHeight = div.scrollHeight;
// We have the current scroll positions saved in
// variables, so now we can append the new element.
div.append(span);
if ((divScrollHeight === divCurrentUserScrollPosition)) {
// Scroll to bottom of div
div.scrollTo({ left: 0, top: div.scrollHeight });
}
The above solutions did not work for me because I was testing on an Android device with the latest Google Play Services version which utilizes the FusedLocationProviderClient. After setting the mock location permission in the app manifest and the app as the specified mock location app in the developer settings (as mentioned in the previous answers), I then added the Kotlin code below which successfully mocked the location.
locationProvider = FusedLocationProviderClient(context)
locationProvider.setMockMode(true)
val loc = Location(providerName)
val mockLocation = Location(providerName) // a string
mockLocation.latitude = latitude // double
mockLocation.longitude = longitude
mockLocation.altitude = loc.altitude
mockLocation.time = System.currentTimeMillis()
mockLocation.accuracy = 1f
mockLocation.elapsedRealtimeNanos = SystemClock.elapsedRealtimeNanos()
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
mockLocation.bearingAccuracyDegrees = 0.1f
mockLocation.verticalAccuracyMeters = 0.1f
mockLocation.speedAccuracyMetersPerSecond = 0.01f
}
// locationManager.setTestProviderLocation(providerName, mockLocation)
locationProvider.setMockLocation(mockLocation)
f = open("Path/To/Your/File.txt", "w") # 'r' for reading and 'w' for writing
f.write("Hello World from " + f.name) # Write inside file
f.close() # Close file
# Method 2shush
with open("Path/To/Your/File.txt", "w") as f: # Opens file and casts as f
f.write("Hello World form " + f.name) # Writing
# File closed automatically
Following the currently top voted answer, I've found using a dataset / data attribute works well.
//Javascript
const input1 = document.querySelector("#input1");
input1.value = "0.00";
input1.dataset.value = input1.value;
//dataset.value will set "data-value" on the input1 HTML element
//and will be used by CSS targetting the dataset attribute
document.querySelectorAll("input").forEach((input) => {
input.addEventListener("input", function() {
this.dataset.value = this.value;
console.log(this);
})
})

You can do this after you validate your data.
if myform.is_valid():
data = myform.cleaned_data
field = data['field']
Also, read the django docs. They are perfect.
Move script tag at the end of BODY instead of HEAD because in current code when the script is computed html element doesn't exist in document.
Since you don't want to you jquery. Use window.onload or document.onload to execute the entire piece of code that you have in current script tag. window.onload vs document.onload

For RHEL-based i386 distributions:
yum install ImageMagick.i386
yum install ImageMagick-devel.i386
pecl install imagick
echo "extension=imagick.so" > /etc/php.d/imagick.ini
service httpd restart
This may also work on other i386 distributions using yum package manager. For x86_64, just replace .i386 with .x86_64
Use capitalize
. From the String documentation:
Returns a copy of str with the first character converted to uppercase and the remainder to lowercase.
"hello".capitalize #=> "Hello"
"HELLO".capitalize #=> "Hello"
"123ABC".capitalize #=> "123abc"
I had a problem like this before, it was the gradle.properties file doesn't exist, only the gradle.properties.txt , so i went to my project folder and i copied & pasted the gradle.properties.txt file but without .txt extension then it finally worked.

You may get this error because you namespaced the file. If so you will need to specify that PHPUnit_Framework_TestCase is in the global namespace by preceding it with a backslash:

I submitted a crude PR to start conversation for correcting the documentation.
a[id]::before {
content: '';
display: block;
height: 50px;
margin: -30px 0 0;
}
That will append a pseudo-element before every a-tag with an id. Adjust values to match the height of your header.
This is an old question but here is my solution to the exact problem if you want to use the USB driver you got from the SDK manager, seeing that the documentation @MeowMeow linked is not too current:
Simple...no need for extra software, but you will need to have installed the USB driver from the SDK manager (like the guy who asked the question) before following these steps.
As a side note, I am running win 8..the steps might differ for you :)
Java Language Specification says that
Program Exit
A program terminates all its activity and exits when one of two things happens:
All the threads that are not daemon threads terminate.
Some thread invokes the exit method of class Runtime or class System, and the exit operation is not forbidden by the security manager.
It means that You should use it when You have big program (well, at lest bigger than this one) and want to finish its execution.
I am surprised that no one mentioned onmousedown
instead of onclick
. The
onclick='return false'
does not catch the browser's default behaviour resulting in (sometimes unwanted) text selection occurring for mousedown
but
onmousedown='return false'
does.
In other words, when I click on a button, its text sometimes becomes accidentally selected changing the look of the button, that may be unwanted. That is the default behaviour that we are trying to prevent here. However, the mousedown
event is registered before click
, so if you only prevent that behaviour inside your click
handler, it will not affect the unwanted selection arising from the mousedown
event. So the text still gets selected. However, preventing default for the mousedown
event will do the job.
When I was trying to accomplish something very similar, I ended up doing something along these lines:
wp-content/themes/resources/functions.php
add_action('init', 'my_php_function');
function my_php_function() {
if (stripos($_SERVER['REQUEST_URI'], 'page-with-custom-php') !== false) {
// add desired php code here
}
}
float them all left
make sure a width is specified that they can all fit in their container (either another div or the window), otherwise they will wrap
Based on (dangerouslySetInnerHTML).
It's a prop that does exactly what you want. However they name it to convey that it should be use with caution
It's more standard to use the format yyyy-mm-dd hh:mm:ss (IE: 2009-06-23 19:30:20)
Using that you won't have to worry about the format of the date (MM/DD/YYYY or DD/MM/YYYY). It will work with all of them.
Or you can use initialize list:
revenue.push_back({"string", map[i].second});
I know I come late, but only recently I was able to implement such "addHeader" to the Adapter. In my FlexibleAdapter project you can call setHeader
on a Sectionable item, then you call showAllHeaders
. If you need only 1 header then the first item should have the header. If you delete this item, then the header is automatically linked to the next one.
Unfortunately footers are not covered (yet).
The FlexibleAdapter allows you to do much more than create headers/sections. You really should have a look: https://github.com/davideas/FlexibleAdapter.
Method call setSelectedIndex("item_value");
doesn't work because setSelectedIndex
use sequential index.
Promise:
An Async Event Handler - The Promise object represents the eventual completion (or failure) of an asynchronous operation, and its resulting value.
Syntax: new Promise(executor);
Eg:
var promise_eg = new Promise(function(resolve, reject) {
setTimeout(function() {
resolve('foo');
}, 300);
});
promise_eg.then(function(value) {
console.log(value);
// expected output: "foo"
});
console.log(promise_eg);
About Promise: It has one pipeline so, it will return values only once when its called. its one way handler so once called you may not able to cancel. useful syntax you can play around, when() and then()
Observables:
Observables are lazy collections of multiple values over time. its really a great approach for async operations. it can be done with rxjs which has cross platform support can use with angular/react etc.
its act like stream liner. can be multi pipeline. so once defined you can subscribe to get return results in many places.
Syntax: import * as Rx from "@reactivex/rxjs";
to init:
Rx.Observable.fromEvent(button, "click"),
Rx.Subject()
etc
to subscribe: RxLogger.getInstance();
Eg:
import { range } from 'rxjs';
import { map, filter } from 'rxjs/operators';
range(1, 200).pipe(
filter(x => x % 2 === 1),
map(x => x + x)
).subscribe(x => console.log(x));
since it support multi pipeline you can subscribe result in different location, it has much possibilities than promises.
Usage:
it has more possibilities like map, filter, pipe, map, concatMap etc
You can use React.Children
to iterate over the children, and then clone each element with new props (shallow merged) using React.cloneElement
. For example:
const Child = ({ doSomething, value }) => (
<button onClick={() => doSomething(value)}>Click Me</button>
);
class Parent extends React.Component{
doSomething = value => {
console.log("doSomething called by child with value:", value);
}
render() {
const childrenWithProps = React.Children.map(this.props.children, child => {
// checking isValidElement is the safe way and avoids a typescript error too
if (React.isValidElement(child)) {
return React.cloneElement(child, { doSomething: this.doSomething });
}
return child;
});
return <div>{childrenWithProps}</div>;
}
}
function App() {
return (
<Parent>
<Child value={1} />
<Child value={2} />
</Parent>
);
}
ReactDOM.render(<App />, document.getElementById("container"));

Alternatively, you can pass props to children with render props. In this approach, the children (which can be children
or any other prop name) is a function which can accept any arguments you want to pass and returns the children:
const Child = ({ doSomething, value }) => (
<button onClick={() => doSomething(value)}>Click Me</button>
);
class Parent extends React.Component{
doSomething = value => {
console.log("doSomething called by child with value:", value);
}
render(){
// note that children is called as a function and we can pass args to it
return <div>{this.props.children(this.doSomething)}</div>
}
};
function App(){
return (
<Parent>
{doSomething => (
<React.Fragment>
<Child doSomething={doSomething} value={1} />
<Child doSomething={doSomething} value={2} />
</React.Fragment>
)}
</Parent>
);
}
ReactDOM.render(<App />, document.getElementById("container"));

Instead of <React.Fragment>
or simply <>
you can also return an array if you prefer.
Your regex should work 'as-is'. Assuming that it is doing what you want it to.
wordA(\s*)wordB(?! wordc)
This means match wordA
followed by 0 or more spaces followed by wordB
, but do not match if followed by wordc
. Note the single space between ?!
and wordc
which means that wordA wordB wordc
will not match, but wordA wordB wordc
will.
Here are some example matches and the associated replacement output:
Note that all matches are replaced no matter how many spaces. There are a couple of other points: -
(?! wordc)
is a negative lookahead, so you wont match lines wordA wordB wordc
which is assume is intended (and is why the last line is not matched). Currently you are relying on the space after ?!
to match the whitespace. You may want to be more precise and use (?!\swordc)
. If you want to match against more than one space before wordc you can use (?!\s*wordc)
for 0 or more spaces or (?!\s*+wordc)
for 1 or more spaces depending on what your intention is.
Of course, if you do want to match lines with wordc after wordB then you shouldn't use a negative lookahead.
*
will match 0 or more spaces so it will match wordAwordB. You may want to consider +
if you want at least one space.
(\s*)
- the brackets indicate a capturing group. Are you capturing the whitespace to a group for a reason? If not you could just remove the brackets, i.e. just use \s
.
Update based on comment
Hello the problem is not the expression but the HTML out put that are not considered as whitespace. it's a Joomla website.
Preserving your original regex you can use:
wordA((?:\s| )*)wordB(?!(?:\s| )wordc)
The only difference is that not the regex matches whitespace OR
. I replaced wordc
with \swordc
since that is more explicit. Note as I have already pointed out that the negative lookahead ?!
will not match when wordB is followed by a single whitespace and wordc. If you want to match multiple whitespaces then see my comments above. I also preserved the capture group around the whitespace, if you don't want this then remove the brackets as already described above.
Example matches:
TO ADD: @Christopher's answer does not work on API 7/8 (as per @Jonny's correct comment) IF you are using colours, instead of drawables. (In my testing, using drawables as per Christopher works fine)
Here is the FIX for 2.3 and below when using colours:
As per @Charles Harley, there is a bug in 2.3 and below where filling the list item with a colour causes the colour to flow out over the whole list. His fix is to define a shape
drawable containing the colour you want, and to use that instead of the colour.
I suggest looking at this link if you want to just use a colour as selector, and are targeting Android 2 (or at least allow for Android 2).

I checked all the above solutions, they don't work. The only possible solution is to catch 'onkeydown' event for each input of the form. You need to attach disableAllInputs to onload of the page or via jquery ready()
/*
* Prevents default behavior of pushing enter button. This method doesn't work,
* if bind it to the 'onkeydown' of the document|form, or to the 'onkeypress' of
* the input. So method should be attached directly to the input 'onkeydown'
*/
function preventEnterKey(e) {
// W3C (Chrome|FF) || IE
e = e || window.event;
var keycode = e.which || e.keyCode;
if (keycode == 13) { // Key code of enter button
// Cancel default action
if (e.preventDefault) { // W3C
e.preventDefault();
} else { // IE
e.returnValue = false;
}
// Cancel visible action
if (e.stopPropagation) { // W3C
e.stopPropagation();
} else { // IE
e.cancelBubble = true;
}
// We don't need anything else
return false;
}
}
/* Disable enter key for all inputs of the document */
function disableAllInputs() {
try {
var els = document.getElementsByTagName('input');
if (els) {
for ( var i = 0; i < els.length; i++) {
els[i].onkeydown = preventEnterKey;
}
}
} catch (e) {
}
}
This works: The way it's set up I called it from the immediate pane, but you can easily create a sub() that will call MoveData once for each month, then just invoke the sub.
You may want to add logic to sort your monthly data after it's all been copied
Public Sub MoveData(MonthNumber As Integer, SheetName As String)
Dim sharePoint As Worksheet
Dim Month As Worksheet
Dim spRange As Range
Dim cell As Range
Set sharePoint = Sheets("Sharepoint")
Set Month = Sheets(SheetName)
Set spRange = sharePoint.Range("A2")
Set spRange = sharePoint.Range("A2:" & spRange.End(xlDown).Address)
For Each cell In spRange
If Format(cell.Value, "MM") = MonthNumber Then
copyRowTo sharePoint.Range(cell.Row & ":" & cell.Row), Month
End If
Next cell
End Sub
Sub copyRowTo(rng As Range, ws As Worksheet)
Dim newRange As Range
Set newRange = ws.Range("A1")
If newRange.Offset(1).Value <> "" Then
Set newRange = newRange.End(xlDown).Offset(1)
Else
Set newRange = newRange.Offset(1)
End If
rng.Copy
newRange.PasteSpecial (xlPasteAll)
End Sub
we can use \b as a word boundary and then; \b\d+\b
I just did git reset --hard
and lost all my uncommitted changes. Luckily, I use an editor (IntelliJ) and I was able to recover the changes from the Local History. Eclipse should allow you to do the same.
so I am assuming that this project you are doing in your private eclipse (not company provided eclipse where you work). The same problem I resolved just as below
quick fix : got to .m2 file --> create a backup of settings.xml --> remove settings.xml --> restart your eclipse.
Sure there is. You can for example use the conditional expressions. For example:
<span th:text="${someObject.someProperty != null} ? ${someObject.someProperty} : 'null value!'">someValue</span>
You can even omit the "else" expression:
<span th:text="${someObject.someProperty != null} ? ${someObject.someProperty}">someValue</span>
You can also take a look at the Elvis operator to display default values.
just use a reference:
Vec3b & color = image.at<Vec3b>(y,x);
color[2] = 13;
Path.Combine(AppDomain.CurrentDomain.BaseDirectory, @"JukeboxV2.0\JukeboxV2.0\Datos\ich will.mp3")

As other answer mentioned depcheck
is good for check unused dependecies in your porject. Use npm outdated
command to check the outdated library.
You should never forcibly kill a thread without cooperating with it.
Killing a thread removes any guarantees that try/finally blocks set up so you might leave locks locked, files open, etc.
The only time you can argue that forcibly killing threads is a good idea is to kill a program fast, but never single threads.

At the bottom of this answer is an example of GLSL code which allows to output the full float
value as color, encoding IEEE 754 binary32
. I use it like follows (this snippet gives out yy
component of modelview matrix):
vec4 xAsColor=toColor(gl_ModelViewMatrix[1][1]);
if(bool(1)) // put 0 here to get lowest byte instead of three highest
gl_FrontColor=vec4(xAsColor.rgb,1);
else
gl_FrontColor=vec4(xAsColor.a,0,0,1);
After you get this on screen, you can just take any color picker, format the color as HTML (appending 00
to the rgb
value if you don't need higher precision, and doing a second pass to get the lower byte if you do), and you get the hexadecimal representation of the float
as IEEE 754 binary32
.
Here's the actual implementation of toColor()
:
const int emax=127;
// Input: x>=0
// Output: base 2 exponent of x if (x!=0 && !isnan(x) && !isinf(x))
// -emax if x==0
// emax+1 otherwise
int floorLog2(float x)
{
if(x==0.) return -emax;
// NOTE: there exist values of x, for which floor(log2(x)) will give wrong
// (off by one) result as compared to the one calculated with infinite precision.
// Thus we do it in a brute-force way.
for(int e=emax;e>=1-emax;--e)
if(x>=exp2(float(e))) return e;
// If we are here, x must be infinity or NaN
return emax+1;
}
// Input: any x
// Output: IEEE 754 biased exponent with bias=emax
int biasedExp(float x) { return emax+floorLog2(abs(x)); }
// Input: any x such that (!isnan(x) && !isinf(x))
// Output: significand AKA mantissa of x if !isnan(x) && !isinf(x)
// undefined otherwise
float significand(float x)
{
// converting int to float so that exp2(genType) gets correctly-typed value
float expo=float(floorLog2(abs(x)));
return abs(x)/exp2(expo);
}
// Input: x\in[0,1)
// N>=0
// Output: Nth byte as counted from the highest byte in the fraction
int part(float x,int N)
{
// All comments about exactness here assume that underflow and overflow don't occur
const float byteShift=256.;
// Multiplication is exact since it's just an increase of exponent by 8
for(int n=0;n<N;++n)
x*=byteShift;
// Cut higher bits away.
// $q \in [0,1) \cap \mathbb Q'.$
float q=fract(x);
// Shift and cut lower bits away. Cutting lower bits prevents potentially unexpected
// results of rounding by the GPU later in the pipeline when transforming to TrueColor
// the resulting subpixel value.
// $c \in [0,255] \cap \mathbb Z.$
// Multiplication is exact since it's just and increase of exponent by 8
float c=floor(byteShift*q);
return int(c);
}
// Input: any x acceptable to significand()
// Output: significand of x split to (8,8,8)-bit data vector
ivec3 significandAsIVec3(float x)
{
ivec3 result;
float sig=significand(x)/2.; // shift all bits to fractional part
result.x=part(sig,0);
result.y=part(sig,1);
result.z=part(sig,2);
return result;
}
// Input: any x such that !isnan(x)
// Output: IEEE 754 defined binary32 number, packed as ivec4(byte3,byte2,byte1,byte0)

Try that. Unless you truly need to stick with the type as submit, then what I provided should work. If you are going to stick with submit, then everything mentioned above is correct, it makes no sense.
You can use the bootstrap template from
which includes all the bootstrap .less files. You can then change variables / update the less files as you want and it will automatically compile the css. When deploying compile the less file to css.
I'd prefer to use [:punct:]
for that. Also, a-zA-Z09-9
could be just [:alnum:]
:

If you don't care about the actual key, a concise way to iterate over all the Map's values would be to use its values()
method
Map<String, List<String>> myMap;
for ( List<String> stringList : myMap.values() ) {
for ( String myString : stringList ) {
// process the string here
}
}
The values()
method is part of the Map interface and returns a Collection view of the values in the map.
Important:
I'm sorry to say that the response from "Borealid" is imprecise and somewhat incorrect - firstly there is no relation to statefulness or statelessness to answer this question, and most importantly the definition of the tuple for a socket is incorrect.
First remember below two rules:
Primary key of a socket: A socket is identified by {SRC-IP, SRC-PORT, DEST-IP, DEST-PORT, PROTOCOL}
not by {SRC-IP, SRC-PORT, DEST-IP, DEST-PORT}
- Protocol is an important part of a socket's definition.
OS Process & Socket mapping: A process can be associated with (can open/can listen to) multiple sockets which might be obvious to many readers.
Example 1: Two clients connecting to same server port means: socket1 {SRC-A, 100, DEST-X,80, TCP}
and socket2{SRC-B, 100, DEST-X,80, TCP}
. This means host A connects to server X's port 80 and another host B also connects to same server X to the same port 80. Now, how the server handles these two sockets depends on if the server is single threaded or multiple threaded (I'll explain this later). What is important is that one server can listen to multiple sockets simultaneously.
To answer the original question of the post:
Irrespective of stateful or stateless protocols, two clients can connect to same server port because for each client we can assign a different socket (as client IP will definitely differ). Same client can also have two sockets connecting to same server port - since such sockets differ by SRC-PORT
. With all fairness, "Borealid" essentially mentioned the same correct answer but the reference to state-less/full was kind of unnecessary/confusing.
To answer the second part of the question on how a server knows which socket to answer. First understand that for a single server process that is listening to same port, there could be more than one sockets (may be from same client or from different clients). Now as long as a server knows which request is associated with which socket, it can always respond to appropriate client using the same socket. Thus a server never needs to open another port in its own node than the original one on which client initially tried to connect. If any server allocates different server-ports after a socket is bound, then in my opinion the server is wasting its resource and it must be needing the client to connect again to the new port assigned.
A bit more for completeness:
Example 2: It's a very interesting question: "can two different processes on a server listen to the same port". If you do not consider protocol as one of parameter defining socket then the answer is no. This is so because we can say that in such case, a single client trying to connect to a server-port will not have any mechanism to mention which of the two listening processes the client intends to connect to. This is the same theme asserted by rule (2). However this is WRONG answer because 'protocol' is also a part of the socket definition. Thus two processes in same node can listen to same port only if they are using different protocol. For example two unrelated clients (say one is using TCP and another is using UDP) can connect and communicate to the same server node and to the same port but they must be served by two different server-processes.
Server Types - single & multiple:
When a server's processes listening to a port that means multiple sockets can simultaneously connect and communicate with the same server-process. If a server uses only a single child-process to serve all the sockets then the server is called single-process/threaded and if the server uses many sub-processes to serve each socket by one sub-process then the server is called multi-process/threaded server. Note that irrespective of the server's type a server can/should always uses the same initial socket to respond back (no need to allocate another server-port).
Suggested Books and rest of the two volumes if you can.
A Note on Parent/Child Process (in response to query/comment of 'Ioan Alexandru Cucu')
Wherever I mentioned any concept in relation to two processes say A and B, consider that they are not related by parent child relationship. OS's (especially UNIX) by design allow a child process to inherit all File-descriptors (FD) from parents. Thus all the sockets (in UNIX like OS are also part of FD) that a process A listening to, can be listened by many more processes A1, A2, .. as long as they are related by parent-child relation to A. But an independent process B (i.e. having no parent-child relation to A) cannot listen to same socket. In addition, also note that this rule of disallowing two independent processes to listen to same socket lies on an OS (or its network libraries) and by far it's obeyed by most OS's. However, one can create own OS which can very well violate this restrictions.
Since adjacent string literals are automatically joint into a single string, you can just use the implied line continuation inside parentheses as recommended by PEP 8:
print("Why, hello there wonderful "
"stackoverflow people!")
You'll need to join twice:
SELECT home.*, away.*, g.network, g.date_start
FROM game AS g
INNER JOIN team AS home
ON home.importid = g.home
INNER JOIN team AS away
ON away.importid = g.away
ORDER BY g.date_start DESC
LIMIT 7

NOTE This is a modified version of @elreimundo
C or C++ itself do not define those identifiers. They are compiler extensions and stand for certain calling conventions. That determines where to put arguments, in what order, where the called function will find the return address, and so on. For example, __fastcall means that arguments of functions are passed over registers.
The Wikipedia Article provides an overview of the different calling conventions found out there.
Here's another option using jQuery grep. Pass true
as the third parameter to ensure grep removes items that match your function.
users = $.grep(users, function(el, idx) {return el.field == "money"}, true)
If you're already using jQuery then no shim is required, which is could be useful as opposed to using Array.filter
.
Your JSON sample is:
{
"status": "ok",
"comment": "",
"result": {
"id": 276,
"firstName": "mohamed",
"lastName": "hussien",
"players": [
"player 1",
"player 2",
"player 3",
"player 4",
"player 5"
]
}
so if you want to save arraylist of modules in your SharedPrefrences so :
1- will convert your returned arraylist for json format using this method
public static String toJson(Object jsonObject) {
return new Gson().toJson(jsonObject);
}
2- Save it in shared prefreneces
PreferencesUtils.getInstance(context).setString("players", toJson((.....ArrayList you want to convert.....)));
3- to retrieve it at any time get JsonString from Shared preferences like that
String playersString= PreferencesUtils.getInstance(this).getString("players");
4- convert it again to array list
public static Object fromJson(String jsonString, Type type) {
return new Gson().fromJson(jsonString, type);
}
ArrayList<String> playersList= (ArrayList<String>) fromJson(playersString,
new TypeToken<ArrayList<String>>() {
}.getType());
this solution also doable if you want to parse ArrayList of Objects Hope it's help you by using Gson Library .
add a default value for your Id lets say in your table definition this will solve your problem.
You are testing if the values of the variables error
and Already
are present in RepoOutput[RepoName.index(repo)]
. If these variables don't exist then an undefined object is used.
Both of your if
and elif
tests therefore are false; there is no undefined object in the value of RepoOutput[RepoName.index(repo)].
I think you wanted to test if certain strings are in the value instead:
{% if "error" in RepoOutput[RepoName.index(repo)] %}
<td id="error"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% elif "Already" in RepoOutput[RepoName.index(repo) %}
<td id="good"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% else %}
<td id="error"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% endif %}
</tr>
Other corrections I made:
{% elif ... %}
instead of {$ elif ... %}
.</tr>
tag out of the if
conditional structure, it needs to be there always.id
attributeNote that most likely you want to use a class
attribute instead here, not an id
, the latter must have a value that must be unique across your HTML document.
Personally, I'd set the class value here and reduce the duplication a little:
{% if "Already" in RepoOutput[RepoName.index(repo)] %}
{% set row_class = "good" %}
{% else %}
{% set row_class = "error" %}
{% endif %}
<td class="{{ row_class }}"> {{ RepoOutput[RepoName.index(repo)] }} </td>
One thing I can suggest you is to extend the storage object to handle objects and arrays.
LocalStorage can handle only strings so you can achieve that using these methods
Storage.prototype.setObj = function(key, obj) {
return this.setItem(key, JSON.stringify(obj))
}
Storage.prototype.getObj = function(key) {
return JSON.parse(this.getItem(key))
}
Using it every values will be converted to json string on set and parsed on get
I am talking here from a theoretical point of view; I have not tried BitLocker.
BitLocker uses AES encryption with a 128-bit key. On a Core2 machine, clocked at 2.53 GHz, encryption speed should be about 110 MB/s, using one core. The two cores could process about 220 MB/s, assuming perfect data transfer and core synchronization with no overhead, and that nothing requires the CPU in the same time (that one hell of an assumption, actually). The X25-M G2 is announced at 250 MB/s read bandwidth (that's what the specs say), so, in "ideal" conditions, BitLocker necessarily involves a bit of a slowdown.
However read bandwidth is not that important. It matters when you copy huge files, which is not something that you do very often. In everyday work, access time is much more important: as a developer, you create, write, read and delete many files, but they are all small (most of them are much smaller than one megabyte). This is what makes SSD "snappy". Encryption does not impact access time. So my guess is that any performance degradation will be negligible(*).
(*) Here I assume that Microsoft's developers did their job properly.
There is one other thing you might want to think about, Currently it can only add the warning class if it is empty, how about removing the class again when the form is not empty anymore.
like this:
$('#apply-form input').blur(function()
{
if( !$(this).val() ) {
$(this).parents('p').addClass('warning');
} else if ($(this).val()) {
$(this).parents('p').removeClass('warning');
}
});
We can also solve this utilizing vectors.
Let's define the segments as [start, end]
. Given two such segments [A, B]
and [C, D]
that both have non-zero length, we can choose one of the endpoints to be used as a reference point so that we get three vectors:
x = 0
y = 1
p = A-C = [C[x]-A[x], C[y]-A[y]]
q = B-A = [B[x]-A[x], B[y]-A[y]]
r = D-C = [D[x]-C[x], D[y]-C[y]]
From there, we can look for an intersection by calculating t and u in p + t*r = u*q
. After playing around with the equation a little, we get:
t = (q[y]*p[x] - q[x]*p[y])/(q[x]*r[y] - q[y]*r[x])
u = (p[x] + t*r[x])/q[x]
Thus, the function is:
def intersects(a, b):
p = [b[0][0]-a[0][0], b[0][1]-a[0][1]]
q = [a[1][0]-a[0][0], a[1][1]-a[0][1]]
r = [b[1][0]-b[0][0], b[1][1]-b[0][1]]
t = (q[1]*p[0] - q[0]*p[1])/(q[0]*r[1] - q[1]*r[0]) \
if (q[0]*r[1] - q[1]*r[0]) != 0 \
else (q[1]*p[0] - q[0]*p[1])
u = (p[0] + t*r[0])/q[0] \
if q[0] != 0 \
else (p[1] + t*r[1])/q[1]
return t >= 0 and t <= 1 and u >= 0 and u <= 1
Let:
>>> n = 1000
>>> x = np.arange(n)
>>> reps = 10000
Zero-cost allocations
A view does not take any additional memory. Thus, these declarations are instantaneous:
# New axis
x[np.newaxis, ...]
# Broadcast to specific shape
np.broadcast_to(x, (reps, n))
Forced allocation
If you want force the contents to reside in memory:
>>> %timeit np.array(np.broadcast_to(x, (reps, n)))
10.2 ms ± 62.3 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
>>> %timeit np.repeat(x[np.newaxis, :], reps, axis=0)
9.88 ms ± 52.4 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
>>> %timeit np.tile(x, (reps, 1))
9.97 ms ± 77.3 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
All three methods are roughly the same speed.
Computation
>>> a = np.arange(reps * n).reshape(reps, n)
>>> x_tiled = np.tile(x, (reps, 1))
>>> %timeit np.broadcast_to(x, (reps, n)) * a
17.1 ms ± 284 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
>>> %timeit x[np.newaxis, :] * a
17.5 ms ± 300 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
>>> %timeit x_tiled * a
17.6 ms ± 240 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
All three methods are roughly the same speed.
Conclusion
If you want to replicate before a computation, consider using one of the "zero-cost allocation" methods. You won't suffer the performance penalty of "forced allocation".

Using the Elastic search DSL API, you may hit the same error with
s = Search(using=client, index="my-index") \
.query("match", category.keyword="Musician")
You can solve it by doing:
s = Search(using=client, index="my-index") \
.query({"match": {"category.keyword":"Musician/Band"}})
In my case I edited a project having this in the AndroidManifest.xml file, and which was ginving me the above error, at runtime:
<uses-sdk
android:minSdkVersion="17"
android:targetSdkVersion="17" />
What I did just, was to change minSdkVersion="17", to minSdkVersion="16". My resulting tag was:
<uses-sdk
android:minSdkVersion="16"
android:targetSdkVersion="17" />
Now I'm not getting the error anymore..
Hope this helps
@NoCanDo: You cannot create an array with different data types because java only supports variables with a specific data type or object. When you are creating an array, you are pulling together an assortment of similar variables -- almost like an extended variable. All of the variables must be of the same type therefore. Java cannot differentiate the data type of your variable unless you tell it what it is. Ex: int
tells all your variables declared to it are of data type int
. What you could do is create 3 arrays with corresponding information.
int bookNumber[] = {1, 2, 3, 4, 5};
int bookName[] = {nameOfBook1, nameOfBook2, nameOfBook3, nameOfBook4, nameOfBook5}
// etc.. etc..
Now, a single index number gives you all the info for that book. Ex: All of your arrays with index number 0 ([0]) have information for book 1.
Here is the code to generate random alphanumeric code. First you have to declare a string of allowed characters what you want to include in random number.and also define max length of string
SecureRandom secureRandom = new SecureRandom();
String CHARACTERS = "ABCDEFGHIJKLMNOPQRSTUVWXYZ123456789";
StringBuilder generatedString= new StringBuilder();
for (int i = 0; i < MAXIMUM_LENGTH; i++) {
int randonSequence = secureRandom .nextInt(CHARACTERS.length());
generatedString.append(CHARACTERS.charAt(randonSequence));
}
Use toString() method to get String from StringBuilder
I am a little late to the party but I thought I'd share a way of doing it, if you have identical types of conditions, i.e. checking if all, any or at given amount of A_1=A_2 and B_1=B_2, this can be done in the following way:
cond_list_1=["1","2","3"]
cond_list_2=["3","2","1"]
nr_conds=1
if len([True for i, j in zip(cond_list_1, cond_list_2) if i == j])>=nr_conds:
print("At least " + str(nr_conds) + " conditions are fullfilled")
if len([True for i, j in zip(cond_list_1, cond_list_2) if i == j])==len(cond_list_1):
print("All conditions are fullfilled")
This means you can just change in the two initial lists, at least for me this makes it easier.
I was able to figure it out by following the answer in this thread: https://stackoverflow.com/a/8968495/1543447
Basically, I renamed all values, function names, and element names to different values so they wouldn't conflict - and it worked!
This feature is built into jqGrid.
setup your grid function as follows.
$('#myGrid').jqGrid({
...
colNames: ['Manager', 'Name', 'HiddenSalary'],
colModel: [
{ name: 'Manager', editable: true },
{ name: 'Price', editable: true },
{ name: 'HiddenSalary', hidden: true , editable: true,
editrules: {edithidden:true}
}
],
...
};
There are other editrules that can be applied but this basic setup would hide the manager's salary in the grid view but would allow editing when the edit form was displayed.
I see both some SQL Server specific and some MySQL specific solutions here, so you might want to clarify which database you need. Though if I had to guess I'd say SQL Server since this is trivial in MySQL.
I also see some solutions that won't work because they fail to take into account the possibility for duplicates, so be careful which ones you accept. Finally, I see a few that will work but that will make two complete scans of the table. You want to make sure the 2nd scan is only looking at 2 values.
SQL Server (pre-2012):
SELECT MIN([column]) AS [column]
FROM (
SELECT TOP 2 [column]
FROM [Table]
GROUP BY [column]
ORDER BY [column] DESC
) a
MySQL:
SELECT `column`
FROM `table`
GROUP BY `column`
ORDER BY `column` DESC
LIMIT 1,1
Update:
SQL Server 2012 now supports a much cleaner (and standard) OFFSET/FETCH syntax:
SELECT TOP 2 [column]
FROM [Table]
GROUP BY [column]
ORDER BY [column] DESC
OFFSET 1 ROWS
FETCH NEXT 1 ROWS ONLY;
It's important to have clear definitions of what terms mean. Unfortunately there appears to be multiple definitions of what static and dynamic arrays mean.
Static variables are variables defined using static memory allocation. This is a general concept independent of C/C++. In C/C++ we can create static variables with global, file, or local scope like this:
int x[10]; //static array with global scope
static int y[10]; //static array with file scope
foo() {
static int z[10]; //static array with local scope
Automatic variables are usually implemented using stack-based memory allocation. An automatic array can be created in C/C++ like this:
foo() {
int w[10]; //automatic array
What these arrays , x, y, z
, and w
have in common is that the size for each of them is fixed and is defined at compile time.
One of the reasons that it's important to understand the distinction between an automatic array and a static array is that static storage is usually implemented in the data section (or BSS section) of an object file and the compiler can use absolute addresses to access the arrays which is impossible with stack-based storage.
What's usually meant by a dynamic array is not one that is resizeable but one implemented using dynamic memory allocation with a fixed size determined at run-time. In C++ this is done using the new
operator.
foo() {
int *d = new int[n]; //dynamically allocated array with size n
But it's possible to create an automatic array with a fixes size defined at runtime using alloca
:
foo() {
int *s = (int*)alloca(n*sizeof(int))
For a true dynamic array one should use something like std::vector
in C++ (or a variable length array in C).
What was meant for the assignment in the OP's question? I think it's clear that what was wanted was not a static or automatic array but one that either used dynamic memory allocation using the new
operator or a non-fixed sized array using e.g. std::vector
.

You can give a function expression a name that is actually private and is only visible from inside of the function ifself:
var factorial = function myself (n) {
if (n <= 1) {
return 1;
}
return n * myself(n-1);
}
typeof myself === 'undefined'
Here myself
is visible only inside of the function itself.
You can use this private name to call the function recursively.
See 13. Function Definition
of the ECMAScript 5 spec:
The Identifier in a FunctionExpression can be referenced from inside the FunctionExpression's FunctionBody to allow the function to call itself recursively. However, unlike in a FunctionDeclaration, the Identifier in a FunctionExpression cannot be referenced from and does not affect the scope enclosing the FunctionExpression.
Please note that Internet Explorer up to version 8 doesn't behave correctly as the name is actually visible in the enclosing variable environment, and it references a duplicate of the actual function (see patrick dw's comment below).
Alternatively you could use arguments.callee
to refer to the current function:
var factorial = function (n) {
if (n <= 1) {
return 1;
}
return n * arguments.callee(n-1);
}
The 5th edition of ECMAScript forbids use of arguments.callee() in strict mode, however:
(From MDN): In normal code arguments.callee refers to the enclosing function. This use case is weak: simply name the enclosing function! Moreover, arguments.callee substantially hinders optimizations like inlining functions, because it must be made possible to provide a reference to the un-inlined function if arguments.callee is accessed. arguments.callee for strict mode functions is a non-deletable property which throws when set or retrieved.

You can manipulate not only opacity, but colour, brightness, luminosity and other properties:
What you can do is set specific width and height to your iframe (for example these could be equal to your window dimensions) and then applying a scale transformation to it. The scale value will be the ratio between your window width and the dimension you wanted to set to your iframe.
E.g.
<iframe width="1024" height="768" src="http://www.bbc.com" style="-webkit-transform:scale(0.5);-moz-transform-scale(0.5);"></iframe>

where pdfData is your base64 encoded pdf like "data:application/pdf;base64,JVBERi0xLjQKJcOkw7zDtsOfCjIgMCBvYmoKPDwvTGVuZ3RoIDMgMCBSL0ZpbHRlci9GbGF0ZURlY29kZT4+CnN0cmVhbQp4nO1cyY4ktxG911fUWUC3kjsTaBTQ1Ytg32QN4IPgk23JMDQ2LB/0+2YsZAQzmZk1PSPIEB..."
Your E
class doesn't have a member of type struct X
, you've just defined a nested struct X
in there (i.e. you've defined a new type).
Try:
#include <iostream>
class E
{
public:
struct X { int v; };
X x; // an instance of `struct X`
};
int main(){
E object;
object.x.v = 1;
return 0;
}
The solution of @bunji works for me, but default options don't always give a good result. I added some useful parameter to tweak the appearance of the table.
import pandas as pd
import matplotlib.pyplot as plt
from pandas.tools.plotting import table
import numpy as np
dates = pd.date_range('20130101',periods=6)
df = pd.DataFrame(np.random.randn(6,4),index=dates,columns=list('ABCD'))
df.index = [item.strftime('%Y-%m-%d') for item in df.index] # Format date
fig, ax = plt.subplots(figsize=(12, 2)) # set size frame
ax.xaxis.set_visible(False) # hide the x axis
ax.yaxis.set_visible(False) # hide the y axis
ax.set_frame_on(False) # no visible frame, uncomment if size is ok
tabla = table(ax, df, loc='upper right', colWidths=[0.17]*len(df.columns)) # where df is your data frame
tabla.auto_set_font_size(False) # Activate set fontsize manually
tabla.set_fontsize(12) # if ++fontsize is necessary ++colWidths
tabla.scale(1.2, 1.2) # change size table
plt.savefig('table.png', transparent=True)
It is wrong to have <input> as a direct child of a <form>
And by the way <input /> may fail on some doctype
Check it with http://validator.w3.org/check
document type does not allow element "INPUT" here; missing one of "P", "H1", "H2", "H3", "H4", "H5", "H6", "PRE", "DIV", "ADDRESS" start-tag
<input type="text" />
The mentioned element is not allowed to appear in the context in which you've placed it; the other mentioned elements are the only ones that are both allowed there and can contain the element mentioned. This might mean that you need a containing element, or possibly that you've forgotten to close a previous element.
One possible cause for this message is that you have attempted to put a block-level element (such as "<p>" or "<table>") inside an inline element (such as "<a>", "<span>", or "<font>").
This command should work:
sed "s/\s/,/g" < infile.txt > outfile.txt
Note that you have to redirect the output to a new file. The input file is not changed in place.
Following are the results when we use both [MaxLength]
and [StringLength]
attributes, in EF code first
. If both are used, [MaxLength]
wins the race. See the test result in studentname
column in below class
public class Student
{
public Student () {}
[Key]
[Column(Order=1)]
public int StudentKey { get; set; }
//[MaxLength(50),StringLength(60)] //studentname column will be nvarchar(50)
//[StringLength(60)] //studentname column will be nvarchar(60)
[MaxLength(50)] //studentname column will be nvarchar(50)
public string StudentName { get; set; }
[Timestamp]
public byte[] RowVersion { get; set; }
}
This is a method that I use to update AppSettings, works for both web and desktop applications. If you need to edit connectionStrings you can get that value from System.Configuration.ConnectionStringSettings config = configFile.ConnectionStrings.ConnectionStrings["YourConnectionStringName"];
and then set a new value with config.ConnectionString = "your connection string";
. Note that if you have any comments in the connectionStrings
section in Web.Config
these will be removed.
private void UpdateAppSettings(string key, string value)
{
System.Configuration.Configuration configFile = null;
if (System.Web.HttpContext.Current != null)
{
configFile =
System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~");
}
else
{
configFile =
ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
}
var settings = configFile.AppSettings.Settings;
if (settings[key] == null)
{
settings.Add(key, value);
}
else
{
settings[key].Value = value;
}
configFile.Save(ConfigurationSaveMode.Modified);
ConfigurationManager.RefreshSection(configFile.AppSettings.SectionInformation.Name);
}

Not in the submit event handler itself, no.
But what you can do is add click handlers to each submit which will inform the submit handler as to which was clicked.
Here's a full example (using jQuery for brevity)
<html>
<head>
<title>Test Page</title>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script type="text/javascript">
jQuery(function($) {
var submitActor = null;
var $form = $('#test');
var $submitActors = $form.find('input[type=submit]');
$form.submit(function(event) {
if (null === submitActor) {
// If no actor is explicitly clicked, the browser will
// automatically choose the first in source-order
// so we do the same here
submitActor = $submitActors[0];
}
console.log(submitActor.name);
// alert(submitActor.name);
return false;
});
$submitActors.click(function(event) {
submitActor = this;
});
});
</script>
</head>
<body>
<form id="test">
<input type="text" />
<input type="submit" name="save" value="Save" />
<input type="submit" name="saveAndAdd" value="Save and add another" />
</form>
</body>

In C++, struct
s do not have a comparison operator generated by default. You need to write your own:
bool operator==(const MyStruct1& lhs, const MyStruct1& rhs)
{
return /* your comparison code goes here */
}
According to the galambalazs post I would add support for touch devices, allowing us to touch but no scroll up or down:
function disable_scroll() {
...
document.ontouchmove = function(e){
e.preventDefault();
}
}
function enable_scroll() {
...
document.ontouchmove = function(e){
return true;
}
}
Yes, you can use SQL IN
operator to search multiple absolute values:
SELECT name FROM products WHERE name IN ( 'Value1', 'Value2', ... );
If you want to use LIKE
you will need to use OR
instead:
SELECT name FROM products WHERE name LIKE '%Value1' OR name LIKE '%Value2';
Using AND
(as you tried) requires ALL conditions to be true, using OR
requires at least one to be true.
That's pretty easy:
class Sample {
private String message = null;
private final Object lock = new Object();
public void newMessage(String x) {
synchronized (lock) {
message = x;
}
}
public String getMessage() {
synchronized (lock) {
String temp = message;
message = null;
return temp;
}
}
}
Note that I didn't either make the methods themselves synchronized or synchronize on this
. I firmly believe that it's a good idea to only acquire locks on objects which only your code has access to, unless you're deliberately exposing the lock. It makes it a lot easier to reassure yourself that nothing else is going to acquire locks in a different order to your code, etc.
I know it is an old question, but I just managed to do so without a pseudo child (but a pseudo wrapper).
If you set the parent to be with no pointer-events
, and then a child div
with pointer-events
set to auto
, it works:)
Note that <img>
tag (for example) doesn't do the trick.
Also remember to set pointer-events
to auto
for other children which have their own event listener, or otherwise they will lose their click functionality.
div.parent { _x000D_
pointer-events: none;_x000D_
}_x000D_
_x000D_
div.child {_x000D_
pointer-events: auto;_x000D_
}_x000D_
_x000D_
div.parent:hover {_x000D_
background: yellow;_x000D_
}
_x000D_
<div class="parent">_x000D_
parent - you can hover over here and it won't trigger_x000D_
<div class="child">hover over the child instead!</div>_x000D_
</div>
_x000D_
Edit:
As Shadow Wizard kindly noted: it's worth to mention this won't work for IE10 and below. (Old versions of FF and Chrome too, see here)
Here I came up with universal method to navigate from any place to root.
You create a new Class file with this class, so that it's accessible from anywhere in your project:
import UIKit
class SharedControllers
{
static func navigateToRoot(viewController: UIViewController)
{
var nc = viewController.navigationController
// If this is a normal view with NavigationController, then we just pop to root.
if nc != nil
{
nc?.popToRootViewControllerAnimated(true)
return
}
// Most likely we are in Modal view, so we will need to search for a view with NavigationController.
let vc = viewController.presentingViewController
if nc == nil
{
nc = viewController.presentingViewController?.navigationController
}
if nc == nil
{
nc = viewController.parentViewController?.navigationController
}
if vc is UINavigationController && nc == nil
{
nc = vc as? UINavigationController
}
if nc != nil
{
viewController.dismissViewControllerAnimated(false, completion:
{
nc?.popToRootViewControllerAnimated(true)
})
}
}
}
Usage from anywhere in your project:
{
...
SharedControllers.navigateToRoot(self)
...
}
I know this is an old post. However, I observed another instance where in the project already has Tomcat added but we still get this error. Did this to resolve that:
Alt + Enter
Project Facets
On the right, next to details, is another tab "Runtimes".
The installed tomcat server will be listed there. Select it.
Save the configuration and DONE!
Hope this helps someone.
When you allocate memory for struct Vector
you just allocate memory for pointer x
, i.e. for space, where its value, which contains address, will be placed. So such way you do not allocate memory for the block, on which y.x
will reference.
I see only one case that you would allow exposure to your internal members to another assembly and that is for testing purposes.
Saying that there is a way to allow "Friend" assemblies access to internals:
In the AssemblyInfo.cs file of the project you add a line for each assembly.
[assembly: InternalsVisibleTo("name of assembly here")]
this info is available here.
Hope this helps.

I think architecture is about the interfaces to humans and/or systems. For insance a web service contract, including protocols and so on, is architecture. How a screen is composed, not colors and such but what fields are there, is architecture.
Design is how something is to be built. What frameworks, language, technology etc. This must of course be aligned with enterprise guidelines and restrictions considering platforms, security and so on.
Unfortunately, there is no short form like numbers have increment/decrement:
i++;
I would like to have similar short expression to invert a boolean, dmth like:
isEmpty!;
I solved my background image issue using this code.
import React from 'react';
import { StyleSheet, Text, View,Alert,ImageBackground } from 'react-native';
import { TextInput,Button,IconButton,Colors,Avatar } from 'react-native-paper';
class SignInScreen extends React.Component {
state = {
UsernameOrEmail : '',
Password : '',
}
render() {
return (
<ImageBackground source={require('../assets/icons/background3.jpg')} style {styles.backgroundImage}>
<Text>React Native App</Text>
</ImageBackground>
);
}
}
export default SignInScreen;
const styles = StyleSheet.create({
backgroundImage: {
flex: 1,
resizeMode: 'cover', // or 'stretch'
}
});
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.imageView.image = [UIImage imageNamed:@"your image name here"];
button.titleLabel.text = @"your text here";
but following code will show label above and image in background
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.background.image = [UIImage imageNamed:@"your image name here"];
button.titleLabel.text = @"your text here";
There is no need to use label and button in same control because UIButton has UILabel and UIimageview properties.
If you only need to support Python 2.6 and 2.7 you can use io.open
instead of open
. io
is the new io subsystem for Python 3, and it exists in Python 2,6 ans 2.7 as well. Please be aware that in Python 2.6 (as well as 3.0) it's implemented purely in python and very slow, so if you need speed in reading files, it's not a good option.
If you need speed, and you need to support Python 2.6 or earlier, you can use codecs.open
instead. It also has an encoding parameter, and is quite similar to io.open
except it handles line-endings differently.
open()
style file handler which streams bytestrings:open(filename, 'rb')
Note the 'b', meaning 'binary'.
I think you will need to do this as three separate statements. I've been looking around and everything i've seen seems to suggest you can do it if you are adding a column, but not if you are altering one.
ALTER TABLE dbo.MyTable
ADD CONSTRAINT my_Con DEFAULT GETDATE() for created
UPDATE MyTable SET Created = GetDate() where Created IS NULL
ALTER TABLE dbo.MyTable
ALTER COLUMN Created DATETIME NOT NULL
Here is example of pseudo-random generator when neither $RANDOM nor /dev/urandom is available
echo $(date +%S) | grep -o .$ | sed s/0/10/
One reason why you might prefer to use a JOIN
rather than NOT IN
is that if the Values in the NOT IN
clause contain any NULL
s you will always get back no results. If you do use NOT IN
remember to always consider whether the sub query might bring back a NULL value!
RE: Question in Comments
'x' NOT IN (NULL,'a','b')
= 'x' <> NULL and 'x' <> 'a' and 'x' <> 'b'
= Unknown and True and True
= Unknown
when I use MVC5, and add the claim here.
public async Task<ClaimsIdentity> GenerateUserIdentityAsync(PATAUserManager manager)
{
// Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
// Add custom user claims here
userIdentity.AddClaim(new Claim(ClaimTypes.Role, this.Role));
return userIdentity;
}
when I'm check the claim result in the SignInAsync function,i can't get the role value use anyway. But...
after this request finished, I can access Role in other action(anther request).
var userWithClaims = (ClaimsPrincipal)User;
Claim CRole = userWithClaims.Claims.First(c => c.Type == ClaimTypes.Role);
so, i think maybe asynchronous cause the IEnumerable updated behind the process.
Try this:
require 'open-uri'
open('image.png', 'wb') do |file|
file << open('http://example.com/image.png').read
end
You can use this
string x = "ABCGH"
char[] charX = x.ToCharArray();
Array.Sort(charX);
This will sort your string.
Besides the answer given above, I just want to add that this error can also occur while importing data with incorrect lines terminated character.
For example I save the dump file in csv format in windows. then while importing
LOAD DATA INFILE '/path_to_csv_folder/db.csv' INTO TABLE table1
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
ESCAPED BY '"'
LINES TERMINATED BY '\n'
IGNORE 1 LINES;
Windows saved end of line as \r\n (i.e. CF LF) where as I was using \n. I was getting crazy why phpMyAdmin was able to import the file while I couldn't. Only when I open the file in notepadd++ and saw the end of file then I realized that mysql was unable to find any lines terminated symbol (and I guess it consider all the lines as input to the field; making it complain.)
Anyway after making from \n to \r\n; it work like a charm.
LOAD DATA INFILE '/path_to_csv_folder/db.csv' INTO TABLE table1
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
ESCAPED BY '"'
LINES TERMINATED BY '\r\n'
IGNORE 1 LINES;
An aggregate function requires a GROUP BY in standard SQL
This is "Get minimum date per title" in plain language
SELECT title, MIN(date) FROM table GROUP BY title
Most RDBMS and the standard require that column is either in the GROUP BY or in a functions (MIN, COUNT etc): MySQL is the notable exception with some extensions that give unpredictable behaviour
There is a difference.
When the ^
character appears outside of []
matches the beginning of the line (or string). When the ^
character appears inside the []
, it matches any character not appearing inside the []
.
If you want to use do()
in your main method there are 2 choices because one is static but other (do()) not
new Foo().do();
static do()
methodHave a look at this sun tutorial
first,i used "localhost:port" format met this error.then I changed the address to "ip:port" format and the problem solved.
In C#:
public bool Is64bit() {
return Marshal.SizeOf(typeof(IntPtr)) == 8;
}
In VB.NET:
Public Function Is64bit() As Boolean
If Marshal.SizeOf(GetType(IntPtr)) = 8 Then Return True
Return False
End Function
To avoid double encoding issue described in taras.roshko's answer and to keep possibility to easily work with query parameters, you can use uriBuilder.Uri.ParseQueryString()
instead of HttpUtility.ParseQueryString()
.
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton runat="server" ID="LnKB" Text='edit' OnClick="LnKB_Click" >
</asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
protected void LnKB_Click(object sender, System.EventArgs e)
{
LinkButton lb = sender as LinkButton;
GridViewRow clickedRow = ((LinkButton)sender).NamingContainer as GridViewRow;
int x = clickedRow.RowIndex;
int id = Convert.ToInt32(yourgridviewname.Rows[x].Cells[0].Text);
lbl.Text = yourgridviewname.Rows[x].Cells[2].Text;
}
Now You can access the InputField's state which is the child of FormEditor .
Basically whenever there is a change in the state of the input field(child) we are getting the value from the event object and then passing this value to the Parent where in the state in the Parent is set.
On button click we are just printing the state of the Input fields.
The key point here is that we are using the props to get the Input Field's id/value and also to call the functions which are set as attributes on the Input Field while we generate the reusable child Input fields.
class InputField extends React.Component{
handleChange = (event)=> {
const val = event.target.value;
this.props.onChange(this.props.id , val);
}
render() {
return(
<div>
<input type="text" onChange={this.handleChange} value={this.props.value}/>
<br/><br/>
</div>
);
}
}
class FormEditorParent extends React.Component {
state = {};
handleFieldChange = (inputFieldId , inputFieldValue) => {
this.setState({[inputFieldId]:inputFieldValue});
}
//on Button click simply get the state of the input field
handleClick = ()=>{
console.log(JSON.stringify(this.state));
}
render() {
const fields = this.props.fields.map(field => (
<InputField
key={field}
id={field}
onChange={this.handleFieldChange}
value={this.state[field]}
/>
));
return (
<div>
<div>
<button onClick={this.handleClick}>Click Me</button>
</div>
<div>
{fields}
</div>
</div>
);
}
}
const App = () => {
const fields = ["field1", "field2", "anotherField"];
return <FormEditorParent fields={fields} />;
};
ReactDOM.render(<App/>, mountNode);
As mentioned in other answers, such as @chinto, this happens when the SOAP:Action header element does not match the Endpoint.
You can find the correct URI to use by looking at the server's WSDL. You will see an operation element with an input child that has an "Action" attribute. That is what your SOAP:Action needs to be on the client request.
<wsdl:operation name="MethodName">
<wsdl:input wsaw:Action="http://tempuri.org/IInterface/MethodName" message="tns:IInterface_MethodName_InputMessage"/>
<wsdl:output wsaw:Action="http://tempuri.org/IInterface/MethodNameResponse" message="tns:IInterface_MethodName_OutputMessage"/>
</wsdl:operation>
Normaly you can GET and POST parameters in a servlet the same way:
request.getParameter("cmd");
But only if the POST data is encoded as key-value pairs of content type: "application/x-www-form-urlencoded" like when you use a standard HTML form.
If you use a different encoding schema for your post data, as in your case when you post a json data stream, you need to use a custom decoder that can process the raw datastream from:
BufferedReader reader = request.getReader();
Json post processing example (uses org.json package )
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
StringBuffer jb = new StringBuffer();
String line = null;
try {
BufferedReader reader = request.getReader();
while ((line = reader.readLine()) != null)
jb.append(line);
} catch (Exception e) { /*report an error*/ }
try {
JSONObject jsonObject = HTTP.toJSONObject(jb.toString());
} catch (JSONException e) {
// crash and burn
throw new IOException("Error parsing JSON request string");
}
// Work with the data using methods like...
// int someInt = jsonObject.getInt("intParamName");
// String someString = jsonObject.getString("stringParamName");
// JSONObject nestedObj = jsonObject.getJSONObject("nestedObjName");
// JSONArray arr = jsonObject.getJSONArray("arrayParamName");
// etc...
}
One way for me to understand wildcards is to think that the wildcard isn't specifying the type of the possible objects that given generic reference can "have", but the type of other generic references that it is is compatible with (this may sound confusing...) As such, the first answer is very misleading in it's wording.
In other words, List<? extends Serializable>
means you can assign that reference to other Lists where the type is some unknown type which is or a subclass of Serializable. DO NOT think of it in terms of A SINGLE LIST being able to hold subclasses of Serializable (because that is incorrect semantics and leads to a misunderstanding of Generics).

For me, restarting my phone did the trick.
To see the contents of array you can use.
1) print_r($array);
or if you want nicely formatted array then:
echo '<pre>'; print_r($array); echo '</pre>';
2) use var_dump($array)
to get more information of the content in the array like datatype and length.
3) you can loop the array using php's foreach();
and get the desired output. more info on foreach in php's documentation website:

In order for me to fix the error I had to install the intermediate certificates in the webserver in order to make the error go away. I was using lighttpd, the original certificate was installed on an IIS server. Hope it helps. These were the certificates I had missing on the server.

$url = "http://localhost:82/slimdemo/RESTAPI/" . $api;
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
switch ($method) {
case "GET":
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "GET");
break;
case "POST":
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "POST");
break;
case "PUT":
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "PUT");
break;
case "DELETE":
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "DELETE");
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($data));
break;
}
$response = curl_exec($curl);
$data = json_decode($response);
/* Check for 404 (file not found). */
$httpCode = curl_getinfo($curl, CURLINFO_HTTP_CODE);
// Check the HTTP Status code
switch ($httpCode) {
case 200:
$error_status = "200: Success";
return ($data);
break;
case 404:
$error_status = "404: API Not found";
break;
case 500:
$error_status = "500: servers replied with an error.";
break;
case 502:
$error_status = "502: servers may be down or being upgraded. Hopefully they'll be OK soon!";
break;
case 503:
$error_status = "503: service unavailable. Hopefully they'll be OK soon!";
break;
default:
$error_status = "Undocumented error: " . $httpCode . " : " . curl_error($curl);
break;
}
curl_close($curl);
echo $error_status;
die;
}
CALL Delete Method
$data = array('id'=>$_GET['did']);
$result = CallAPI('DELETE', "DeleteCategory", $data);
CALL Post Method
$data = array('title'=>$_POST['txtcategory'],'description'=>$_POST['txtdesc']);
$result = CallAPI('POST', "InsertCategory", $data);

This is the code to subtract one date from another. This example converts the dates to objects as the getTime() function won't work unless it's an Date object.
var dat1 = document.getElementById('inputDate').value;
var date1 = new Date(dat1)//converts string to date object
alert(date1);
var dat2 = document.getElementById('inputFinishDate').value;
var date2 = new Date(dat2)
alert(date2);
var oneDay = 24 * 60 * 60 * 1000; // hours*minutes*seconds*milliseconds
var diffDays = Math.abs((date1.getTime() - date2.getTime()) / (oneDay));
alert(diffDays);
Edit
For angular 6.1 and newer, use the KeyValuePipe as suggested by Londeren.
For angular 6.0 and older
To make things easier, you can create a pipe.
import {Pipe, PipeTransform} from '@angular/core';
@Pipe({name: 'getValues'})
export class GetValuesPipe implements PipeTransform {
transform(map: Map<any, any>): any[] {
let ret = [];
map.forEach((val, key) => {
ret.push({
key: key,
val: val
});
});
return ret;
}
}
<li *ngFor="let recipient of map |getValues">
As it it pure, it will not be triggered on every change detection, but only if the reference to the map
variable changes
Fixed it by opting out of Ivy as per documentation.
Change tsconfig.app.json to opt out of Ivy.

It doesn't compile because T could be anything, and not everything will have the myvar
field.
You could make myvar
a property on ITest
:
public ITest
{
string myvar{get;}
}
and implement it on the classes as a property:
public class MyClass1 : ITest
{
public string myvar{ get { return "hello 1"; } }
}
and then put a generic constraint on your method:
public void PrintGeneric<T>(T test) where T : ITest
{
Console.WriteLine("Generic : " + test.myvar);
}
but in that case to be honest you are better off just passing in an ITest:
public void PrintGeneric(ITest test)
{
Console.WriteLine("Generic : " + test.myvar);
}
Trim your String value by creating a trim function
var text = " ";
if($.trim(text.length == 0){
console.log("Text is empty");
}
else
{
console.log("Text is not empty");
}

The problem is that the DLL is registered on the 32 bit version of the windows registry, and the application is using the 64 bit version.
Solution: Go into the Project Properties, Compile tab and click "Advanced Compile Options...". Change "Target CPU" to x86, click OK, save and try again.

At Microsoft website, it shows that native OLEDB provider is applied to SQL server directly and another OLEDB provider called OLEDB Provider for ODBC to access other Database, such as Sysbase, DB2 etc. There are different kinds of component under OLEDB Provider.

One of my friends is writing a graphics app using NVIDIA CUDA. Application fits in very nicely with OOP paradigm and the problem can be decomposed into modules neatly. However, to use CUDA you need to use C, which doesn't support inheritance. Therefore, you need to be clever.
a) You devise a clever system which will emulate inheritance to a certain extent. It can be done!
i) You can use a hook system, which expects every child C of parent P to have a certain override for function F. You can make children register their overrides, which will be stored and called when required.
ii) You can use struct memory alignment feature to cast children into parents.
This can be neat but it's not easy to come up with future-proof, reliable solution. You will spend lots of time designing the system and there is no guarantee that you won't run into problems half-way through the project. Implementing multiple inheritance is even harder, if not almost impossible.
b) You can use consistent naming policy and use divide and conquer approach to create a program. It won't have any inheritance but because your functions are small, easy-to-understand and consistently formatted you don't need it. The amount of code you need to write goes up, it's very hard to stay focused and not succumb to easy solutions (hacks). However, this ninja way of coding is the C way of coding. Staying in balance between low-level freedom and writing good code. Good way to achieve this is to write prototypes using a functional language. For example, Haskell is extremely good for prototyping algorithms.
I tend towards approach b. I wrote a possible solution using approach a, and I will be honest, it felt very unnatural using that code.
I usually use *
when I want to get all the strings that contain the wanted characters.
*
used in regex, replaces all characters.
Used in SASS or CSS would be something like [id*="s"]
and it will get all DOM elements with id "s......".
/* add red color to all div with id s .... elements */
div[id^="s"] {
color: red;
}
I think you must firstly add a .wav file to Resources. For example you have sound file named Sound.wav. After you added the Sound.wav file to Resources, you can use this code:
System.Media.SoundPlayer player = new System.Media.SoundPlayer(Properties.Resources.Sound);
player.Play();
This is another way to play sound.
As has already been shown here, there are many ways of declaring multiple
constructors in PHP, but none of them are the correct
way of doing so (since PHP technically doesn't allow it).
But it doesn't stop us from hacking this functionality...
Here's another example:
<?php
class myClass {
public function __construct() {
$get_arguments = func_get_args();
$number_of_arguments = func_num_args();
if (method_exists($this, $method_name = '__construct'.$number_of_arguments)) {
call_user_func_array(array($this, $method_name), $get_arguments);
}
}
public function __construct1($argument1) {
echo 'constructor with 1 parameter ' . $argument1 . "\n";
}
public function __construct2($argument1, $argument2) {
echo 'constructor with 2 parameter ' . $argument1 . ' ' . $argument2 . "\n";
}
public function __construct3($argument1, $argument2, $argument3) {
echo 'constructor with 3 parameter ' . $argument1 . ' ' . $argument2 . ' ' . $argument3 . "\n";
}
}
$object1 = new myClass('BUET');
$object2 = new myClass('BUET', 'is');
$object3 = new myClass('BUET', 'is', 'Best.');

In Bootstrap 4 you can use classes like mt-5
, mb-5
, my-5
, mx-5
(y for both top and bottom, x for both left and right).
According to their site:
The classes are named using the format {property}{sides}-{size} for xs and {property}{sides}-{breakpoint}-{size} for sm, md, lg, and xl.
$('input:radio[name=theme]:checked').val();
Depending on the purpose of setting the display property, you might want to take a look at
$("#yourElementID").show()
and
$("#yourElementID").hide()
You say that you have a list of widgets to change dynamically. Do you want to reuse and reconfigure existing widgets, or create all new widgets and delete the old ones? It affects the answer.
If you want to reuse the existing widgets, just reconfigure them. Or, if you just want to hide some of them temporarily, use the corresponding "forget" method to hide them. If you mapped them with pack()
calls, you would hide with pack_forget()
(or just forget()
) calls. Accordingly, grid_forget()
to hide gridded widgets, and place_forget()
for placed widgets.
If you do not intend to reuse the widgets, you can destroy them with a straight destroy()
call, like widget.destroy()
, to free up resources.
Comparator does everything that comparable does, plus more.
| | Comparable | Comparator ._______________________________________________________________________________ Is used to allow Collections.sort to work | yes | yes Can compare multiple fields | yes | yes Lives inside the class you’re comparing and serves | | as a “default” way to compare | yes | yes Can live outside the class you’re comparing | no | yes Can have multiple instances with different method names | no | yes Input arguments can be a list of | just Object| Any type Can use enums | no | yes
I found the best approach to use comparators as anonymous classes as follows:
private static void sortAccountsByPriority(List<AccountRecord> accounts) {
Collections.sort(accounts, new Comparator<AccountRecord>() {
@Override
public int compare(AccountRecord a1, AccountRecord a2) {
return a1.getRank().compareTo(a2.getRank());
}
});
}
You can create multiple versions of such methods right inside the class you’re planning to sort. So you can have:
sortAccountsByPriorityAndType
etc...
Now, you can use these sort methods anywhere and get code reuse. This gives me everything a comparable would, plus more ... so I don’t see any reason to use comparable at all.
This is what I am doing for my need, Where I need to send the login data to API as form data and the Javascript Object(userData) is getting converted automatically to URL encoded data
var deferred = $q.defer();
$http({
method: 'POST',
url: apiserver + '/authenticate',
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
transformRequest: function (obj) {
var str = [];
for (var p in obj)
str.push(encodeURIComponent(p) + "=" + encodeURIComponent(obj[p]));
return str.join("&");
},
data: userData
}).success(function (response) {
//logics
deferred.resolve(response);
}).error(function (err, status) {
deferred.reject(err);
});
This how my Userdata is
var userData = {
grant_type: 'password',
username: loginData.userName,
password: loginData.password
}
Clearly:
Server side generating a token example
private string GenerateToken(string userName)
{
var someClaims = new Claim[]{
new Claim(JwtRegisteredClaimNames.UniqueName, userName),
new Claim(JwtRegisteredClaimNames.Email, GetEmail(userName)),
new Claim(JwtRegisteredClaimNames.NameId,Guid.NewGuid().ToString())
};
SecurityKey securityKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(_settings.Tokenizer.Key));
var token = new JwtSecurityToken(
issuer: _settings.Tokenizer.Issuer,
audience: _settings.Tokenizer.Audience,
claims: someClaims,
expires: DateTime.Now.AddHours(_settings.Tokenizer.ExpiryHours),
signingCredentials: new SigningCredentials(securityKey, SecurityAlgorithms.HmacSha256)
);
return new JwtSecurityTokenHandler().WriteToken(token);
}
(note: Tokenizer is my helper class that contains Issuer Audience etc..)
Definitely:
Client side getting a token for authentication
public async Task<string> GetToken()
{
string token = "";
var siteSettings = DependencyResolver.Current.GetService<SiteSettings>();
var client = new HttpClient();
client.BaseAddress = new Uri(siteSettings.PopularSearchRequest.StaticApiUrl);
client.DefaultRequestHeaders.Accept.Clear();
//client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
StatisticUserModel user = new StatisticUserModel()
{
Password = siteSettings.PopularSearchRequest.Password,
Username = siteSettings.PopularSearchRequest.Username
};
string jsonUser = JsonConvert.SerializeObject(user, Formatting.Indented);
var stringContent = new StringContent(jsonUser, Encoding.UTF8, "application/json");
var response = await client.PostAsync(siteSettings.PopularSearchRequest.StaticApiUrl + "/api/token/new", stringContent);
token = await response.Content.ReadAsStringAsync();
return token;
}
You can use this token for the authorization (that is in the subsequent requests)
There is a HUGE difference between VARCHAR and TEXT. While VARCHAR fields can be indexed, TEXT fields cannot. VARCHAR type fields are stored inline while TEXT are stored offline, only pointers to TEXT data is actually stored in the records.
If you have to index your field for faster search, update or delete than go for VARCHAR, no matter how big. A VARCHAR(10000000) will never be the same as a TEXT field bacause these two data types are different in nature.
than go for TEXT.
We can break both a $(selector).each()
loop and a $.each()
loop at a particular iteration by making the callback function return false
. Returning non-false
is the same as a continue statement in a for
loop; it will skip immediately to the next iteration.
return false; // this is equivalent of 'break' for jQuery loop
return; // this is equivalent of 'continue' for jQuery loop
Note that $(selector).each()
and $.each()
are different functions.
References:
This doesn't answer your specific question, but it DOES provide you with a solution to your problem: use a for loop to run through the object collection. then you will have the current index you are working on.
// Untested
for (int i = 0; i < collection.Count; i++)
{
Console.WriteLine("My index is " + i);
}
The easiest way is to pickle it using to_pickle
:
df.to_pickle(file_name) # where to save it, usually as a .pkl
Then you can load it back using:
df = pd.read_pickle(file_name)
Note: before 0.11.1 save
and load
were the only way to do this (they are now deprecated in favor of to_pickle
and read_pickle
respectively).
Another popular choice is to use HDF5 (pytables) which offers very fast access times for large datasets:
import pandas as pd
store = pd.HDFStore('store.h5')
store['df'] = df # save it
store['df'] # load it
More advanced strategies are discussed in the cookbook.
Since 0.13 there's also msgpack which may be be better for interoperability, as a faster alternative to JSON, or if you have python object/text-heavy data (see this question).
For an easy fix, you could
echo 1 > /proc/sys/vm/overcommit_memory
if your're sure that your system has enough memory. See Linux over commit heuristic.
Try indextank.
As the case of elastic search, it was conceived to be much easier to use than lucene/solr. It also includes very flexible scoring system that can be tweaked without reindexing.
Shortest solution:
$domain = parse_url('http://google.com', PHP_URL_HOST);
This is @Jason's answer but with simplified output
SELECT name, CASE WHEN value = 1 THEN 'YES' ELSE 'NO' END AS 'Enabled'
FROM sys.configurations WHERE name = 'clr enabled'
The above returns the following:
| name | Enabled |
-------------------------
| clr enabled | YES |

Actually the orderBy
filter can take as a parameter not only a string but also a function. From the orderBy
documentation: https://docs.angularjs.org/api/ng/filter/orderBy):
function: Getter function. The result of this function will be sorted using the <, =, > operator.
So, you could write your own function. For example, if you would like to compare cards based on a sum of opt1 and opt2 (I'm making this up, the point is that you can have any arbitrary function) you would write in your controller:
$scope.myValueFunction = function(card) {
return card.values.opt1 + card.values.opt2;
};
and then, in your template:
ng-repeat="card in cards | orderBy:myValueFunction"
The other thing worth noting is that orderBy
is just one example of AngularJS filters so if you need a very specific ordering behaviour you could write your own filter (although orderBy
should be enough for most uses cases).

There are two different ways to implement inserting data from one table to another table.
This method is used when the table is already created in the database earlier and the data is to be inserted into this table from another table. If columns listed in insert clause and select clause are same, they are not required to list them. It is good practice to always list them for readability and scalability purpose.
----Create testable
CREATE TABLE TestTable (FirstName VARCHAR(100), LastName VARCHAR(100))
----INSERT INTO TestTable using SELECT
INSERT INTO TestTable (FirstName, LastName)
SELECT FirstName, LastName
FROM Person.Contact
WHERE EmailPromotion = 2
----Verify that Data in TestTable
SELECT FirstName, LastName
FROM TestTable
----Clean Up Database
DROP TABLE TestTable
This method is used when the table is not created earlier and needs to be created when data from one table is to be inserted into the newly created table from another table. The new table is created with the same data types as selected columns.
----Create a new table and insert into table using SELECT INSERT
SELECT FirstName, LastName
INTO TestTable
FROM Person.Contact
WHERE EmailPromotion = 2
----Verify that Data in TestTable
SELECT FirstName, LastName
FROM TestTable
----Clean Up Database
DROP TABLE TestTable
For those who are looking for the fastest way to iterate over strings in php, Ive prepared a benchmark testing.
The first method in which you access string characters directly by specifying its position in brackets and treating string like an array:
$string = "a sample string for testing";
$char = $string[4] // equals to m
I myself thought the latter is the fastest method, but I was wrong.
As with the second method (which is used in the accepted answer):
$string = "a sample string for testing";
$string = str_split($string);
$char = $string[4] // equals to m
This method is going to be faster cause we are using a real array and not assuming one to be an array.
Calling the last line of each of the above methods for 1000000
times lead to these benchmarking results:
Using string[i]
0.24960017204285 Seconds
Using str_split
0.18720006942749 Seconds
Which means the second method is way faster.
For Mac Users:
It could be that another instance of eclipse is running in the background. If so, use either Force Quit eclipse or
ps -ef |grep eclipse kill -9 pid
to all the eclipse instances, and start the new workspace
You can do this with a single call, like so:
scanf( "%i %i %i %i", &minx, &maxx, &miny, &maxy);
Here's something along the same lines. Chances are, you'll be using less anyway, so try this:
less -p pattern file
It will highlight the pattern and jump to the first occurrence of it in the file.
You can jump to the next occurence with n
and to the previous occurence with p
. Quit with q
.
Given
std::vector<Rule>& topPriorityRules;
The correct way to remove the first element of the referenced vector is
topPriorityRules.erase(topPriorityRules.begin());
which is exactly what you suggested.
Looks like i need to do iterator overloading.
There is no need to overload an iterator in order to erase first element of std::vector
.
P.S. Vector (dynamic array) is probably a wrong choice of data structure if you intend to erase from the front.
I am working through the same need and I believe your timeframe is incorrect.
Try these:
You should be using 24 hours as your base. The number after -mtime should be relative to 24 hours. Thus -.5 is the equivalent of 12 hours, because 12 hours is half of 24 hours.
Is this what you are after?

Try this:
XmlDocument doc = new XmlDocument();
doc.Load(@"C:\Path\To\Xml\File.xml");
Or alternatively if you have the XML in a string use the LoadXml
method.
Once you have it loaded, you can use SelectNodes
and SelectSingleNode
to query specific values, for example:
XmlNode node = doc.SelectSingleNode("//Company/Email/text()");
// node.Value contains "[email protected]"
Finally, note that your XML is invalid as it doesn't contain a single root node. It must be something like this:
<Data>
<Employee>
<Name>Test</Name>
<ID>123</ID>
</Employee>
<Company>
<Name>ABC</Name>
<Email>[email protected]</Email>
</Company>
</Data>
Maybe try this?
SELECT * INTO tmpFerdeen (
SELECT top(100)*
FROM Customers
UNION All
SELECT top(100)*
FROM CustomerEurope
UNION All
SELECT top(100)*
FROM CustomerAsia
UNION All
SELECT top(100)*
FROM CustomerAmericas)
This way you can set the fontSize and can handle it in just one class

I've had a few cranberry-vodkas tonight so I might be missing something...Is setting the range necessary? Why not use:
Activeworkbook.Sheets("Game").Range("A1").value = "Subtotal"
Does this fail as well?
Looks like you tried something similar:
'Worksheets("Game").Range("A1") = "Asdf"
However, Worksheets is a collection, so you can't reference "Game". I think you need to use the Sheets object instead.
Check if it is null or not e.g
if(Session["mykey"] != null)
{
// Session is not expired
}
else
{
//Session is expired
}
if not exist "%USERPROFILE%\.qgis-custom\" (
mkdir "%USERPROFILE%\.qgis-custom" 2>nul
if not errorlevel 1 (
xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e
)
)
You have it almost done. The logic is correct, just some little changes.
This code checks for the existence of the folder (see the ending backslash, just to differentiate a folder from a file with the same name).
If it does not exist then it is created and creation status is checked. If a file with the same name exists or you have no rights to create the folder, it will fail.
If everyting is ok, files are copied.
All paths are quoted to avoid problems with spaces.
It can be simplified (just less code, it does not mean it is better). Another option is to always try to create the folder. If there are no errors, then copy the files
mkdir "%USERPROFILE%\.qgis-custom" 2>nul
if not errorlevel 1 (
xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e
)
In both code samples, files are not copied if the folder is not being created during the script execution.
EDITED - As dbenham comments, the same code can be written as a single line
md "%USERPROFILE%\.qgis-custom" 2>nul && xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e
The code after the &&
will only be executed if the previous command does not set errorlevel. If mkdir
fails, xcopy
is not executed.

When I saw this question I thought of when I had to generate UUIDs. I can't take credit for the code, as I am sure I found it here on stackoverflow. If you dont want the dashes in your string then take out the dashes. Here is the function:
function generateUUID() {
var d = new Date().getTime();
var uuid = 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g,function(c) {
var r = (d + Math.random()*16)%16 | 0;
d = Math.floor(d/16);
return (c=='x' ? r : (r&0x7|0x8)).toString(16);
});
return uuid.toUpperCase();
}

There is another solution for testing APIs on development server.
HTTP Basic Authentication
only for web routesWeb server configuration for nginx
and Laravel
would be like this:
location /api {
try_files $uri $uri/ /index.php?$query_string;
}
location / {
try_files $uri $uri/ /index.php?$query_string;
auth_basic "Enter password";
auth_basic_user_file /path/to/.htpasswd;
}
Authorization: Bearer
will do the job of defending the development server against web crawlers and other unwanted visitors.
You can also send an array via FormData
this way:
var formData = new FormData;
var arr = ['this', 'is', 'an', 'array'];
for (var i = 0; i < arr.length; i++) {
formData.append('arr[]', arr[i]);
}
So you can write arr[]
the same way as you do it with a simple HTML form. In case of PHP it should work.

I thought I would answer my own question, since I'm taking a different path than suggested in the answers. Nonetheless, thanks to those who answered.
First, a brief synopsis of my experiences with GitPython, PyGit, and Dulwich:
Also, StGit looks interesting, but I would need the functionality extracted into a separate module and do not want wait for that to happen right now.
In (much) less time than I spent trying to get the three modules above working, I managed to get git commands working via the subprocess module, e.g.
def gitAdd(fileName, repoDir):
cmd = ['git', 'add', fileName]
p = subprocess.Popen(cmd, cwd=repoDir)
p.wait()
gitAdd('exampleFile.txt', '/usr/local/example_git_repo_dir')
This isn't fully incorporated into my program yet, but I'm not anticipating a problem, except maybe speed (since I'll be processing hundreds or even thousands of files at times).
Maybe I just didn't have the patience to get things going with Dulwich or GitPython. That said, I'm hopeful the modules will get more development and be more useful soon.
I would end it with NULL
. Why? Because you can't do either of these:
array[index] == '\0'
array[index] == "\0"
The first one is comparing a char *
to a char
, which is not what you want. You would have to do this:
array[index][0] == '\0'
The second one doesn't even work. You're comparing a char *
to a char *
, yes, but this comparison is meaningless. It passes if the two pointers point to the same piece of memory. You can't use ==
to compare two strings, you have to use the strcmp()
function, because C has no built-in support for strings outside of a few (and I mean few) syntactic niceties. Whereas the following:
array[index] == NULL
Works just fine and conveys your point.
If you don't want a separate CSS file, you can use inline CSS:
<h1>This text should be bold, <span style="font-weight:normal">but this text should not</span></h1>
However, as Madara's comment suggests, you might want to consider putting the unbolded part in a different header, depending on the use case involved.
Am I getting it because the act of calling it via e.extractAll("th") also passes in self as an argument?
Yes, that's precisely it. If you like, the first parameter is the object name, e
that you are calling it with.
And if so, by removing the self in the call, would I be making it some kind of class method that can be called like Extractor.extractAll("th")?
Not quite. A classmethod needs the @classmethod
decorator, and that accepts the class as the first paramater (usually referenced as cls
). The only sort of method that is given no automatic parameter at all is known as a staticmethod, and that again needs a decorator (unsurprisingly, it's @staticmethod
). A classmethod is used when it's an operation that needs to refer to the class itself: perhaps instantiating objects of the class; a staticmethod is used when the code belongs in the class logically, but requires no access to class or instance.
But yes, both staticmethods and classmethods can be called by referencing the classname as you describe: Extractor.extractAll("th")
.

To answer the comment of unutbu:
Because the default handlers handle redirects (codes in the 300 range), and codes in the 100-299 range indicate success, you will usually only see error codes in the 400-599 range. Source
I have added app.UseStaticFiles();
this code in my startup.cs than it is fixed
I like to use:
(strlen(string) + 1 ) * sizeof(char)
This will give you the buffer size in bytes. You can use this with snprintf() may help:
const char* message = "%s, World!";
char* string = (char*)malloc((strlen(message)+1))*sizeof(char));
snprintf(string, (strlen(message)+1))*sizeof(char), message, "Hello");
Cheers! Function: size_t strlen (const char *s)
I recommend using glob to accomplish that task.
var glob = require( 'glob' )
, path = require( 'path' );
glob.sync( './routes/**/*.js' ).forEach( function( file ) {
require( path.resolve( file ) );
});
First, it usually does not matter that much in practice. Most hash functions are "good enough".
But if you really care, you should know that it is a research subject by itself. There are thousand of papers about that. You can still get a PhD today by studying & designing hashing algorithms.
Your second hash function might be slightly better, because it probably should separate the string "ab"
from the string "ba"
. On the other hand, it is probably less quick than the first hash function. It may, or may not, be relevant for your application.
I'll guess that hash functions used for genome strings are quite different than those used to hash family names in telephone databases. Perhaps even some string hash functions are better suited for German, than for English or French words.
Many software libraries give you good enough hash functions, e.g. Qt has qhash, and C++11 has std::hash in <functional>
, Glib has several hash functions in C, and POCO has some hash function.
I quite often have hashing functions involving primes (see Bézout's identity) and xor, like e.g.
#define A 54059 /* a prime */
#define B 76963 /* another prime */
#define C 86969 /* yet another prime */
#define FIRSTH 37 /* also prime */
unsigned hash_str(const char* s)
{
unsigned h = FIRSTH;
while (*s) {
h = (h * A) ^ (s[0] * B);
s++;
}
return h; // or return h % C;
}
But I don't claim to be an hash expert. Of course, the values of A
, B
, C
, FIRSTH
should preferably be primes, but you could have chosen other prime numbers.
Look at some MD5 implementation to get a feeling of what hash functions can be.
Most good books on algorithmics have at least a whole chapter dedicated to hashing. Start with wikipages on hash function & hash table.
You could convert it to a string instead of printing the list directly:
print(", ".join(LIST))
If the elements in the list aren't strings, you can convert them to string using either repr
(if you want quotes around strings) or str
(if you don't), like so:
LIST = [1, "foo", 3.5, { "hello": "bye" }]
print( ", ".join( repr(e) for e in LIST ) )
Which gives the output:
1, 'foo', 3.5, {'hello': 'bye'}
Note: this answer was originally written with regard to older versions of SourceTree for Windows, and is now out-of-date.
See my new answer for the current version of SourceTree for Windows, 1.5.2.0. I'm leaving this answer behind for historical purposes.
as I'm on Windows I don't have a command line tool nor do I know how to use one :( Is it the only way to get that sorted out? The GUI doesn't cover all the git's functions? — Original Poster
Regarding Git GUIs, no, they don't cover all of Git's functions. They don't even come close. I suggest you check out one of the answers in How do I edit an incorrect commit message in Git?, Git is flexible enough that there are multiple solutions...from the command line.
SourceTree might actually come with the msysgit bash shell already, or it might be able to use the standard Windows command shell. Either way, you open it up form SourceTree by clicking the Terminal button:
You set which terminal SourceTree uses (bash or Windows) here:
That being said, here's one way you can do it in SourceTree. Since you mentioned in the comments that you don't mind "reverting back to the faulty commit" (by which I assume you actually mean resetting, which is a different operation in Git), then here are the steps:
Reset current branch to this commit
, and selecting the hard reset option from the drop down. Regarding this comment:
if it's not possible because it's already pushed to Bitbucket, I would not mind creating a new repository and starting over.
Does this mean that you're the only person working on the repo? This is important because it's not trivial to change the history of a repo (like by amending a commit) without causing problems for your collaborators. However, assuming that you're the only person working on the repo, then the next thing you would want to do is force push your changed history to the remote.
Be aware, though, that because you did a hard reset to the faulty commit, then force pushing causes you to lose all work that come after it previously. If that's okay, then you might need to use the following command at the command line to do the force push, because I couldn't find an option to do it in SourceTree:
git push remote-repo head -f
This also assumes that BitBucket will allow you to force push to a repo.
You should really learn how to use Git from the command line anyways though, it'll make you more proficient in Git. #ProTip, use msysgit and turn on Quick Edit mode on in the terminal properties, so that you can double click to highlight a line of text, right click to copy, and right click again to paste. It's pretty quick.
