I just implemented this with Swift 2.0 for iOS9 on Xcode 7 (beta 6), works fine here.
override func viewWillAppear(animated: Bool) {
super.viewWillAppear(animated)
registerKeyboardNotifications()
}
func registerKeyboardNotifications() {
NSNotificationCenter.defaultCenter().addObserver(self, selector: "keyboardWillShow:", name: UIKeyboardWillShowNotification, object: nil)
NSNotificationCenter.defaultCenter().addObserver(self, selector: "keyboardWillHide:", name: UIKeyboardWillHideNotification, object: nil)
}
deinit {
NSNotificationCenter.defaultCenter().removeObserver(self)
}
func keyboardWillShow(notification: NSNotification) {
let userInfo: NSDictionary = notification.userInfo!
let keyboardSize = userInfo.objectForKey(UIKeyboardFrameBeginUserInfoKey)!.CGRectValue.size
let contentInsets = UIEdgeInsetsMake(0, 0, keyboardSize.height, 0)
scrollView.contentInset = contentInsets
scrollView.scrollIndicatorInsets = contentInsets
var viewRect = view.frame
viewRect.size.height -= keyboardSize.height
if CGRectContainsPoint(viewRect, textField.frame.origin) {
let scrollPoint = CGPointMake(0, textField.frame.origin.y - keyboardSize.height)
scrollView.setContentOffset(scrollPoint, animated: true)
}
}
func keyboardWillHide(notification: NSNotification) {
scrollView.contentInset = UIEdgeInsetsZero
scrollView.scrollIndicatorInsets = UIEdgeInsetsZero
}
Edited for Swift 3
Seems like you only need to set the contentInset
and scrollIndicatorInset
with Swift 3, the scrolling/contentOffset is done automatically..
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
registerKeyboardNotifications()
}
func registerKeyboardNotifications() {
NotificationCenter.default.addObserver(self,
selector: #selector(keyboardWillShow(notification:)),
name: NSNotification.Name.UIKeyboardWillShow,
object: nil)
NotificationCenter.default.addObserver(self,
selector: #selector(keyboardWillHide(notification:)),
name: NSNotification.Name.UIKeyboardWillHide,
object: nil)
}
deinit {
NotificationCenter.default.removeObserver(self)
}
func keyboardWillShow(notification: NSNotification) {
let userInfo: NSDictionary = notification.userInfo! as NSDictionary
let keyboardInfo = userInfo[UIKeyboardFrameBeginUserInfoKey] as! NSValue
let keyboardSize = keyboardInfo.cgRectValue.size
let contentInsets = UIEdgeInsets(top: 0, left: 0, bottom: keyboardSize.height, right: 0)
scrollView.contentInset = contentInsets
scrollView.scrollIndicatorInsets = contentInsets
}
func keyboardWillHide(notification: NSNotification) {
scrollView.contentInset = .zero
scrollView.scrollIndicatorInsets = .zero
}
I have been using the latter for a lot of nice lightweight animations. You can use it crossfade two views, or fade one in in front of another, or fade it out. You can shoot a view over another like a banner, you can make a view stretch or shrink... I'm getting a lot of mileage out of beginAnimation
/commitAnimations
.
Don't think that all you can do is:
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:myview cache:YES];
Here is a sample:
[UIView beginAnimations:nil context:NULL]; {
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationDuration:1.0];
[UIView setAnimationDelegate:self];
if (movingViewIn) {
// after the animation is over, call afterAnimationProceedWithGame
// to start the game
[UIView setAnimationDidStopSelector:@selector(afterAnimationProceedWithGame)];
// [UIView setAnimationRepeatCount:5.0]; // don't forget you can repeat an animation
// [UIView setAnimationDelay:0.50];
// [UIView setAnimationRepeatAutoreverses:YES];
gameView.alpha = 1.0;
topGameView.alpha = 1.0;
viewrect1.origin.y = selfrect.size.height - (viewrect1.size.height);
viewrect2.origin.y = -20;
topGameView.alpha = 1.0;
}
else {
// call putBackStatusBar after animation to restore the state after this animation
[UIView setAnimationDidStopSelector:@selector(putBackStatusBar)];
gameView.alpha = 0.0;
topGameView.alpha = 0.0;
}
[gameView setFrame:viewrect1];
[topGameView setFrame:viewrect2];
} [UIView commitAnimations];
As you can see, you can play with alpha, frames, and even sizes of a view. Play around. You may be surprised with its capabilities.
CALayer * pLayer = self.layer.presentationLayer;
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView animateWithDuration:0.001 animations:^{
self.frame = pLayer.frame;
}];
In my case, I wanted to add 10 more rows into the tableview (for a "show more results" type of functionality) and I did the following:
NSInteger tempNumber = self.numberOfRows;
self.numberOfRows += 10;
NSMutableArray *arrayOfIndexPaths = [[NSMutableArray alloc] init];
for (NSInteger i = tempNumber; i < self.numberOfRows; i++) {
[arrayOfIndexPaths addObject:[NSIndexPath indexPathForRow:i inSection:0]];
}
[self.tableView beginUpdates];
[self.tableView insertRowsAtIndexPaths:arrayOfIndexPaths withRowAnimation:UITableViewRowAnimationTop];
[self.tableView endUpdates];
In most cases, instead of "self.numberOfRows", you would usually use the count of the array of objects for the tableview. So to make sure this solution works well for you, "arrayOfIndexPaths" needs to be an accurate array of the index paths of the rows being inserted. If the row exists for any of this index paths, the code might crash, so you should use the method "reloadRowsAtIndexPaths:withRowAnimation:" for those index pathds to avoid crashing
If you have more then 1 dimension array
with open("file.txt", 'w') as output:
for row in values:
output.write(str(row) + '\n')
Code to write without '[' and ']'
with open("file.txt", 'w') as file:
for row in values:
s = " ".join(map(str, row))
file.write(s+'\n')
On windows launching default browser with a predefined url:
Tools > Build System > New Build System:

"cmd": ["cmd","/K","start http://localhost/projects/Reminder/"]
}
ctrl + B and voila!
I know its an old post, but just in case anyone is looking here. I added this to my style.xml and it worked for me.

If you're looking for a document-level key event handling, then binding it during componentDidMount
is the best way (as shown by Brad Colthurst's codepen example):
class ActionPanel extends React.Component {
constructor(props){
super(props);
this.escFunction = this.escFunction.bind(this);
}
escFunction(event){
if(event.keyCode === 27) {
//Do whatever when esc is pressed
}
}
componentDidMount(){
document.addEventListener("keydown", this.escFunction, false);
}
componentWillUnmount(){
document.removeEventListener("keydown", this.escFunction, false);
}
render(){
return (
<input/>
)
}
}
Note that you should make sure to remove the key event listener on unmount to prevent potential errors and memory leaks.
EDIT: If you are using hooks, you can use this useEffect
structure to produce a similar effect:
const ActionPanel = (props) => {
const escFunction = useCallback((event) => {
if(event.keyCode === 27) {
//Do whatever when esc is pressed
}
}, []);
useEffect(() => {
document.addEventListener("keydown", escFunction, false);
return () => {
document.removeEventListener("keydown", escFunction, false);
};
}, []);
return (
<input />
)
};
According to many c compilers:
<<
is an arithmetic left shift or bitwise left shift.>>
is an arithmetic right shiftor bitwise right shift.select * from temptable
where rnum --unique key
in
(
SELECT RNUM --unique key
FROM temptable
WHERE ( HistoryStatus
) IN (SELECT HistoryStatus
FROM temptable
GROUP BY
HistoryStatus
HAVING COUNT(*) <= 1));
I have not tested this code. I have used similar code and it works. The syntax is in Oracle.
If you're inserting text from a database or such (which one usually do), convert all "<br />
"'s to &vbCrLf. Works great for me :)
Put that file in assets.
For project created in Android Studio project you need to create assets folder under the main folder.
Read that file as:
public String loadJSONFromAsset(Context context) {
String json = null;
try {
InputStream is = context.getAssets().open("file_name.json");
int size = is.available();
byte[] buffer = new byte[size];
is.read(buffer);
is.close();
json = new String(buffer, "UTF-8");
} catch (IOException ex) {
ex.printStackTrace();
return null;
}
return json;
}
and then you can simply read this string
return by this function as
JSONObject obj = new JSONObject(json_return_by_the_function);
For further details regarding JSON see http://www.vogella.com/articles/AndroidJSON/article.html
Hope you will get what you want.
On *nix, you can use comm. The answer to the question is:
comm -1 -2 file1.sorted file2.sorted
# where file1 and file2 are sorted and piped into *.sorted
Here's the full usage of comm
:
comm [-1] [-2] [-3 ] file1 file2
-1 Suppress the output column of lines unique to file1.
-2 Suppress the output column of lines unique to file2.
-3 Suppress the output column of lines duplicated in file1 and file2.
Also note that it is important to sort the files before using comm, as mentioned in the man pages.
datejs could parse following, you might want to try out.
Date.parse('1997-07-16T19:20:15') // ISO 8601 Formats
Date.parse('1997-07-16T19:20:30+01:00') // ISO 8601 with Timezone offset
Edit: Regex version
x = "2011-01-28T19:30:00EST"
MM = ["January", "February","March","April","May","June","July","August","September","October","November", "December"]
xx = x.replace(
/(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):\d{2}(\w{3})/,
function($0,$1,$2,$3,$4,$5,$6){
return MM[$2-1]+" "+$3+", "+$1+" - "+$4%12+":"+$5+(+$4>12?"PM":"AM")+" "+$6
}
)
Result
January 28, 2011 - 7:30PM EST
Edit2: I changed my timezone to EST and now I got following
x = "2011-01-28T19:30:00-05:00"
MM = {Jan:"January", Feb:"February", Mar:"March", Apr:"April", May:"May", Jun:"June", Jul:"July", Aug:"August", Sep:"September", Oct:"October", Nov:"November", Dec:"December"}
xx = String(new Date(x)).replace(
/\w{3} (\w{3}) (\d{2}) (\d{4}) (\d{2}):(\d{2}):[^(]+\(([A-Z]{3})\)/,
function($0,$1,$2,$3,$4,$5,$6){
return MM[$1]+" "+$2+", "+$3+" - "+$4%12+":"+$5+(+$4>12?"PM":"AM")+" "+$6
}
)
return

If the column is not in the WHERE/JOIN/GROUP BY/ORDER BY
, but only in the column list in the SELECT
clause is where you use INCLUDE
.
The INCLUDE
clause adds the data at the lowest/leaf level, rather than in the index tree.
This makes the index smaller because it's not part of the tree
INCLUDE columns
are not key columns in the index, so they are not ordered.
This means it isn't really useful for predicates, sorting etc as I mentioned above. However, it may be useful if you have a residual lookup in a few rows from the key column(s)
The problem with your code is in the line:
for(i in length(namevector))
You need to ask yourself: what is length(namevector)
? It's one number. So essentially you're saying:
for(i in 11)
df[,i] <- NA
Or more simply:
df[,11] <- NA
That's why you're getting an error. What you want is:
for(i in namevector)
df[,i] <- NA
Or more simply:
df[,namevector] <- NA
I am using a a very simple aproach. After a file has been uploaded, i shortly remove the input control, using *ngIf. That will cause the input field being removed from the dom and re-added, consequencely it is a new control, and therefore it is emply:
showUploader: boolean = true;
async upload($event) {
await dosomethingwiththefile();
this.showUploader = false;
setTimeout(() =>{ this.showUploader = true }, 100);
}
_x000D_
<input type="file" (change)="upload($event)" *ngIf="showUploader">

As an addon to Dima V's answer this is what I did to make this work for me.
// First declare the window global outside the class
declare let window: any;
// Inside the required class method
let globVarName = window.globVarName;
For the record, the spring.jpa.hibernate.ddl-auto
property is Spring Data JPA specific and is their way to specify a value that will eventually be passed to Hibernate under the property it knows, hibernate.hbm2ddl.auto
.
The values create
, create-drop
, validate
, and update
basically influence how the schema tool management will manipulate the database schema at startup.
For example, the update
operation will query the JDBC driver's API to get the database metadata and then Hibernate compares the object model it creates based on reading your annotated classes or HBM XML mappings and will attempt to adjust the schema on-the-fly.
The update
operation for example will attempt to add new columns, constraints, etc but will never remove a column or constraint that may have existed previously but no longer does as part of the object model from a prior run.
Typically in test case scenarios, you'll likely use create-drop
so that you create your schema, your test case adds some mock data, you run your tests, and then during the test case cleanup, the schema objects are dropped, leaving an empty database.
In development, it's often common to see developers use update
to automatically modify the schema to add new additions upon restart. But again understand, this does not remove a column or constraint that may exist from previous executions that is no longer necessary.
In production, it's often highly recommended you use none
or simply don't specify this property. That is because it's common practice for DBAs to review migration scripts for database changes, particularly if your database is shared across multiple services and applications.
i had the same problem and found another little workaround: i have a provisioner script that is added form the docker build environment. In the script i set the environment variable dependent on a ping check:
Dockerfile:
ADD script.sh /tmp/script.sh
RUN /tmp/script.sh
script.sh:
if ping -c 1 ix.de ; then
echo "direct internet doing nothing"
else
echo "proxy environment detected setting proxy"
export http_proxy=<proxy address>
fi
this is still somewhat crude but worked for me
After a little bit of research along with help from some of the answers here:
SELECT 1
SELECT 1 FROM DUAL
SELECT 1 FROM any_existing_table WHERE 1=0
or
SELECT 1 FROM INFORMATION_SCHEMA.SYSTEM_USERS
or
CALL NOW()
HSQLDB (tested with version 1.8.0.10)
Note: I tried using a WHERE 1=0
clause on the second query, but it didn't work as a value for Apache Commons DBCP's validationQuery
, since the query doesn't return any rows
VALUES 1
or SELECT 1 FROM SYSIBM.SYSDUMMY1
SELECT 1 FROM SYSIBM.SYSDUMMY1
select count(*) from systables
You can achieve this with: EventTarget.dispatchEvent(event)
and by passing in a new KeyboardEvent as the event.
For example: element.dispatchEvent(new KeyboardEvent('keypress', {'key': 'a'}))
Working example:
// get the element in question_x000D_
const input = document.getElementsByTagName("input")[0];_x000D_
_x000D_
// focus on the input element_x000D_
input.focus();_x000D_
_x000D_
// add event listeners to the input element_x000D_
input.addEventListener('keypress', (event) => {_x000D_
console.log("You have pressed key: ", event.key);_x000D_
});_x000D_
_x000D_
input.addEventListener('keydown', (event) => {_x000D_
console.log(`key: ${event.key} has been pressed down`);_x000D_
});_x000D_
_x000D_
input.addEventListener('keyup', (event) => {_x000D_
console.log(`key: ${event.key} has been released`);_x000D_
});_x000D_
_x000D_
// dispatch keyboard events_x000D_
input.dispatchEvent(new KeyboardEvent('keypress', {'key':'h'}));_x000D_
input.dispatchEvent(new KeyboardEvent('keydown', {'key':'e'}));_x000D_
input.dispatchEvent(new KeyboardEvent('keyup', {'key':'y'}));
_x000D_
<input type="text" placeholder="foo" />

Here's a pure JavaScript function which will simulate a click (or any mouse event) on a target element:
function simulatedClick(target, options) {
var event = target.ownerDocument.createEvent('MouseEvents'),
options = options || {},
opts = { // These are the default values, set up for un-modified left clicks
type: 'click',
canBubble: true,
cancelable: true,
view: target.ownerDocument.defaultView,
detail: 1,
screenX: 0, //The coordinates within the entire page
screenY: 0,
clientX: 0, //The coordinates within the viewport
clientY: 0,
ctrlKey: false,
altKey: false,
shiftKey: false,
metaKey: false, //I *think* 'meta' is 'Cmd/Apple' on Mac, and 'Windows key' on Win. Not sure, though!
button: 0, //0 = left, 1 = middle, 2 = right
relatedTarget: null,
};
//Merge the options with the defaults
for (var key in options) {
if (options.hasOwnProperty(key)) {
opts[key] = options[key];
}
}
//Pass in the options
event.initMouseEvent(
opts.type,
opts.canBubble,
opts.cancelable,
opts.view,
opts.detail,
opts.screenX,
opts.screenY,
opts.clientX,
opts.clientY,
opts.ctrlKey,
opts.altKey,
opts.shiftKey,
opts.metaKey,
opts.button,
opts.relatedTarget
);
//Fire the event
target.dispatchEvent(event);
}
Here's a working example: http://www.spookandpuff.com/examples/clickSimulation.html
You can simulate a click on any element in the DOM. Something like simulatedClick(document.getElementById('yourButtonId'))
would work.
You can pass in an object into options
to override the defaults (to simulate which mouse button you want, whether Shift/Alt/Ctrl are held, etc. The options it accepts are based on the MouseEvents API.
I've tested in Firefox, Safari and Chrome. Internet Explorer might need special treatment, I'm not sure.
Your use of @PathParam is incorrect. It does not follow these requirements as documented in the javadoc here. I believe you just want to POST the JSON entity. You can fix this in your resource method to accept JSON entity.
@Path("/hello")
public class Hello {
@POST
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public JSONObject sayPlainTextHello(JSONObject inputJsonObj) throws Exception {
String input = (String) inputJsonObj.get("input");
String output = "The input you sent is :" + input;
JSONObject outputJsonObj = new JSONObject();
outputJsonObj.put("output", output);
return outputJsonObj;
}
}
And, your client code should look like this:
ClientConfig config = new DefaultClientConfig();
Client client = Client.create(config);
client.addFilter(new LoggingFilter());
WebResource service = client.resource(getBaseURI());
JSONObject inputJsonObj = new JSONObject();
inputJsonObj.put("input", "Value");
System.out.println(service.path("rest").path("hello").accept(MediaType.APPLICATION_JSON).post(JSONObject.class, inputJsonObj));
GetLogicalDrives() enumerates all mounted disk partitions, not physical drives.
You can enumerate the drive letters with (or without) GetLogicalDrives, then call QueryDosDevice() to find out which physical drive the letter is mapped to.
Alternatively, you can decode the information in the registry at HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices. The binary data encodings there are not obvious, however. If you have a copy of Russinovich and Solomon's book Microsoft Windows Internals, this registry hive is discussed in Chapter 10.

A variant exists in which you can specify a prefix and suffix too.
See here for an implementation using foldLeft, which is much more verbose, but perhaps worth looking at for education's sake.
dict1
is a symbol that references an underlying dictionary object. Assigning dict1
to dict2
merely assigns the same reference. Changing a key's value via the dict2
symbol changes the underlying object, which also affects dict1
. This is confusing.
It is far easier to reason about immutable values than references, so make copies whenever possible:
person = {'name': 'Mary', 'age': 25}
one_year_later = {**person, 'age': 26} # does not mutate person dict
This is syntactically the same as:
one_year_later = dict(person, age=26)
yes you can, but you need to use aux routing. you will need to give a name to your router-outlet:
<router-outlet name="auxPathName"></router-outlet>
and setup your route config:
@RouteConfig([
{path:'/', name: 'RetularPath', component: OneComponent, useAsDefault: true},
{aux:'/auxRoute', name: 'AuxPath', component: SecondComponent}
])
Check out this example, and also this video.
Update for RC.5 Aux routes has changed a bit: in your router outlet use a name:
<router-outlet name="aux">
In your router config:
{path: '/auxRouter', component: secondComponentComponent, outlet: 'aux'}
According to a discussion with Android Developers on Google+, running the new Map API on the emulator is not possible at the moment.
(The comment is from Zhelyazko Atanasov yesterday at 23:18, I don't know how to link directly to it)
Also, you don't see the "(via Bazaar)" part when running from an actual device, and the update button open the Play Store. I am assuming Bazaar is meant to provide Google Play Services on the Android emulator, but it is not ready yet...
Most of the answers forgot about non English characters !!!
strlen
counts BYTES, not characters, that is why it is and it's sibling functions works fine with English characters, because English characters are stored in 1 byte in both UTF-8 and ASCII encodings, you need to use the multibyte string functions mb_*
This will work with any character encoded in UTF-8
// 8 characters in 12 bytes
$string = "abcd????";
$charsCount = mb_strlen($string, 'UTF-8');
for($i = 0; $i < $charsCount; $i++){
$char = mb_substr($string, $i, 1, 'UTF-8');
var_dump($char);
}
This outputs
string(1) "a"
string(1) "b"
string(1) "c"
string(1) "d"
string(2) "?"
string(2) "?"
string(2) "?"
string(2) "?"
If your JSON is without key you can do it like this:
library[library.length] = {"foregrounds" : foregrounds,"backgrounds" : backgrounds};
So, try this:
var library = {[{
"title" : "Gold Rush",
"foregrounds" : ["Slide 1","Slide 2","Slide 3"],
"backgrounds" : ["1.jpg","","2.jpg"]
}, {
"title" : California",
"foregrounds" : ["Slide 1","Slide 2","Slide 3"],
"backgrounds" : ["3.jpg","4.jpg","5.jpg"]
}]
}
Then:
library[library.length] = {"title" : "Gold Rush", "foregrounds" : ["Howdy","Slide 2"], "backgrounds" : ["1.jpg",""]};
You can un-check the build automatically in Project menu and then build by hand by type Ctrl + B, or clicking an icon the appears to the right of the printer icon.

In addition to existing good answers, note that Jackson 1.9 improved handling by adding "property unification", meaning that ALL annotations from difference parts of a logical property are combined, using (hopefully) intuitive precedence.
In Jackson 1.8 and prior, only field and getter annotations were used when determining what and how to serialize (writing JSON); and only and setter annotations for deserialization (reading JSON). This sometimes required addition of "extra" annotations, like annotating both getter and setter.
With Jackson 1.9 and above these extra annotations are NOT needed. It is still possible to add those; and if different names are used, one can create "split" properties (serializing using one name, deserializing using other): this is occasionally useful for sort of renaming.
UPDATE
While these methods work, newer versions of VS Code uses the Ctrl+] shortcut to indent a block of code once, and Ctrl+[ to remove indentation.
This method detects the indentation in a file and indents accordingly.You can change the size of indentation by clicking on the Select Indentation setting in the bottom right of VS Code (looks something like "Spaces: 2"), selecting "Indent using Spaces" from the drop-down menu and then selecting by how many spaces you would like to indent.
Like Seth's answer, but uses Object.keys()
instead:
const varToString = varObj => Object.keys(varObj)[0]_x000D_
_x000D_
const someVar = 42_x000D_
const displayName = varToString({ someVar })_x000D_
console.log(displayName)
_x000D_
I think the default place for access logs is
%SystemDrive%\inetpub\logs\LogFiles
Otherwise, check under IIS Manager, select the computer on the left pane, and in the middle pane, go under "Logging" in the IIS area. There you will se the default location for all sites (this is however overridable on all sites)
You could also look into
%SystemDrive%\Windows\System32\LogFiles\HTTPERR
Which will contain similar log files that only represents errors.
I you just need an array of chars:
arr = list(str)
If you want to split the str by a particular str:
# str = "temp//temps" will will be ['temp', 'temps']
arr = str.split("//")
as.name(char[1])
will work, although I'm not sure why you'd ever really want to do this -- the quotes won't get carried over in a paste
for example:
> paste("I am counting to", char[1], char[2], char[3])
[1] "I am counting to one two three"
Performetrics provides a convenient Stopwatch class, just the way you need. It can measure wall-clock time and more: it also measures CPU time (user time and system time) if you need. It's small, free and you can download from Maven Central. More information and examples can be found here: https://obvj.net/performetrics
Stopwatch sw = new Stopwatch();
sw.start();
// Your code
sw.stop();
sw.printStatistics(System.out);
// Sample output:
// +-----------------+----------------------+--------------+
// | Counter | Elapsed time | Time unit |
// +-----------------+----------------------+--------------+
// | Wall clock time | 85605718 | nanoseconds |
// | CPU time | 78000500 | nanoseconds |
// | User time | 62400400 | nanoseconds |
// | System time | 15600100 | nanoseconds |
// +-----------------+----------------------+--------------+
You can convert the metrics to any time unit (nanoseconds, milliseconds, seconds, etc...)
PS: I am the author of the tool.
Because in Python 3, print statement
has been replaced with a print() function
, with keyword arguments to replace most of the special syntax of the old print statement. So you have to write it as
print("Hello World")
But if you write this in a program and someone using Python 2.x tries to run it, they will get an error. To avoid this, it is a good practice to import print function:
from __future__ import print_function
Now your code works on both 2.x & 3.x.
Check out below examples also to get familiar with print() function.
Old: print "The answer is", 2*2
New: print("The answer is", 2*2)
Old: print x, # Trailing comma suppresses newline
New: print(x, end=" ") # Appends a space instead of a newline
Old: print # Prints a newline
New: print() # You must call the function!
Old: print >>sys.stderr, "fatal error"
New: print("fatal error", file=sys.stderr)
Old: print (x, y) # prints repr((x, y))
New: print((x, y)) # Not the same as print(x, y)!

The problem is that you are not specifying the name of the remote: Instead of
git remote add https://github.com/username/project.git
you should use:
git remote add origin https://github.com/username/project.git
just use android:buttonTint="@color/colorPrimary"
attribute on tag, hope it will help
See here for an example from the OpenJPA docs. CascadeType.ALL
means it will do all actions.
Quote:
CascadeType.PERSIST: When persisting an entity, also persist the entities held in its fields. We suggest a liberal application of this cascade rule, because if the EntityManager finds a field that references a new entity during the flush, and the field does not use CascadeType.PERSIST, it is an error.
CascadeType.REMOVE: When deleting an entity, it also deletes the entities held in this field.
CascadeType.REFRESH: When refreshing an entity, also refresh the entities held in this field.
CascadeType.MERGE: When merging entity state, also merge the entities held in this field.

suppose you have a button:
<button onclick="backBtn();">Back...</button>
Here the code of the backBtn method:
function backBtn(){
parent.history.back();
return false;
}
If you are starting emulator for Flutter applications, then you can run below command -
> flutter emulators --launch [Emulator ID]
In my case, emulator id is Pixel_2_API_29 as i created it with AVD manager in Android studio. so the command in my case is below -
> flutter emulators --launch Pixel_2_API_29

Good that you've managed to get it working with the html5 mode but it is also possible to make it work in the hashbang mode.

I am using this script after I rename my iOS Project. It helps to change the directories name and make the names in sync.
http://github.com/ytbryan/rename
NOTE: you will need to manually change the scheme's name.
I also need the container name or Id which a script requires to attach to the container. took some tweaking but this works perfectly well for me...
export svr=$(docker ps --format "table {{.ID}}"| sed 's/CONTAINER ID//g' | sed '/^[[:space:]]*$/d')
docker exec -it $svr bash
The sed command is needed to get rid of the fact that the words CONTAINER ID gets printed too ... but I just need the actual id stored in a var.
Use this query this will give your output:
select
t.name
,( select
count (*) as num_value
from Table
where num =t.num) cnt
from Table t;
Here is the example i have tried and it is working for me:
Create the XML file SoapRequestFile.xml
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tem="http://tempuri.org/">
<soapenv:Header/>
<soapenv:Body>
<tem:GetConversionRate>
<!--Optional:-->
<tem:CurrencyFrom>USD</tem:CurrencyFrom>
<!--Optional:-->
<tem:CurrencyTo>INR</tem:CurrencyTo>
<tem:RateDate>2018-12-07</tem:RateDate>
</tem:GetConversionRate>
</soapenv:Body>
</soapenv:Envelope>
And here the code in java:
import java.io.File;
import java.io.FileInputStream;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.InputStreamEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;
import org.junit.Assert;
import org.testng.annotations.Test;
import io.restassured.path.json.JsonPath;
import io.restassured.path.xml.XmlPath;
@Test
public void getMethod() throws Exception {
//wsdl file :http://currencyconverter.kowabunga.net/converter.asmx?wsdl
File soapRequestFile = new File(".\\SOAPRequest\\SoapRequestFile.xml");
CloseableHttpClient client = HttpClients.createDefault(); //create client
HttpPost request = new HttpPost("http://currencyconverter.kowabunga.net/converter.asmx"); //Create the request
request.addHeader("Content-Type", "text/xml"); //adding header
request.setEntity(new InputStreamEntity(new FileInputStream(soapRequestFile)));
CloseableHttpResponse response = client.execute(request);//Execute the command
int statusCode=response.getStatusLine().getStatusCode();//Get the status code and assert
System.out.println("Status code: " +statusCode );
Assert.assertEquals(200, statusCode);
String responseString = EntityUtils.toString(response.getEntity(),"UTF-8");//Getting the Response body
System.out.println(responseString);
XmlPath jsXpath= new XmlPath(responseString);//Converting string into xml path to assert
String rate=jsXpath.getString("GetConversionRateResult");
System.out.println("rate returned is: " + rate);
}
Both are the same.
I usually use int[] array = new int[10];
, because of better (contiguous) readability of the type int[]
.
I also faced a similar issue, the problem was the form was inside a folder and the file .aspx.designer.cs
I had the namespace referencing specifically to that directory; which caused the error to appear in several components:
El nombre no existe en el contexto actual
This in your case, a possible solution is to leave the namespace line of the Members_Jobs.aspx.designer.cs
file specified globally, ie change this
namespace stman.Members {
For this
namespace stman {
It's what helped me solve the problem.
I hope to be helpful
Here is my suggestion. If you want to extract text from PDF, you could import the pdf file into Google Docs, then export it to a more friendly format such as .html, .odf, .rtf, .txt, etc. All of this using the Drive API. It is free* and robust. Take a look at:
https://developers.google.com/drive/v2/reference/files/insert https://developers.google.com/drive/v2/reference/files/get
Because it is a rest API, it is compatible with ALL programing languages. The links I posted aboove have working examples for many languages including: Java, .NET, Python, PHP, Ruby, and others.
I hope it helps.
Thanks to marc_s's answer I solved my original problem - inspired to take it a step further and post one approach to transforming a whole table at a time - tsql script to generate the alter column statements:
DECLARE @tableName VARCHAR(MAX)
SET @tableName = 'affiliate'
--EXEC sp_columns @tableName
SELECT 'Alter table ' + @tableName + ' alter column ' + col.name
+ CASE ( col.user_type_id )
WHEN 231
THEN ' nvarchar(' + CAST(col.max_length / 2 AS VARCHAR) + ') '
END + 'collate Latin1_General_CI_AS ' + CASE ( col.is_nullable )
WHEN 0 THEN ' not null'
WHEN 1 THEN ' null'
END
FROM sys.columns col
WHERE object_id = OBJECT_ID(@tableName)
gets: ALTER TABLE Affiliate ALTER COLUMN myTable NVARCHAR(4000) COLLATE Latin1_General_CI_AS NOT NULL
I'll admit to being puzzled by the need to col.max_length / 2 -
To answer your question title, "How to use Rank() in SQL Server," this is how it works:
I will use this set of data as an example:
create table #tmp
(
column1 varchar(3),
column2 varchar(5),
column3 datetime,
column4 int
)
insert into #tmp values ('AAA', 'SKA', '2013-02-01 00:00:00', 10)
insert into #tmp values ('AAA', 'SKA', '2013-01-31 00:00:00', 15)
insert into #tmp values ('AAA', 'SKB', '2013-01-31 00:00:00', 20)
insert into #tmp values ('AAA', 'SKB', '2013-01-15 00:00:00', 5)
insert into #tmp values ('AAA', 'SKC', '2013-02-01 00:00:00', 25)
You have a partition which basically specifies grouping.
In this example, if you partition by column2, the rank function will create ranks for groups of column2 values. There will be different ranks for rows where column2 = 'SKA' than rows where column2 = 'SKB' and so on.
The ranks are decided like this: The rank for every record is one plus the number of ranks that come before it in its partition. The rank will only increment when one of the fields you selected (other than the partitioned field(s)) is different than the ones that come before it. If all of the selected fields are the same, then the ranks will tie and both will be assigned the value, one.
Knowing this, if we only wanted to select one value from each group in column two, we could use this query:
with cte as
(
select *,
rank() over (partition by column2
order by column3) rnk
from t
) select * from cte where rnk = 1 order by column3;
COLUMN1 | COLUMN2 | COLUMN3 |COLUMN4 | RNK
------------------------------------------------------------------------------
AAA | SKB | January, 15 2013 00:00:00+0000 |5 | 1
AAA | SKA | January, 31 2013 00:00:00+0000 |15 | 1
AAA | SKC | February, 01 2013 00:00:00+0000 |25 | 1
your filter would work, but you need to return true on matching objects in the function passed to the filter for it to grab them.
var $previous = $('.navlink').filter(function() {
return $(this).data("selected") == true
});
I am using Jasmine protractor and I was getting errors like
- Expected [ 'rgba(255, 255, 255, 1)' ] to contain '#fff'.
Below function worked fine for me.
function RGBAToHexA(test:string) {
let sep = test.toString().indexOf(",") > -1 ? "," : " ";
const rgba = test.toString().substring(5).split(")")[0].split(sep);
console.log(rgba)
let r = (+rgba[0]).toString(16),
g = (+rgba[1]).toString(16),
b = (+rgba[2]).toString(16),
a = Math.round(+rgba[3] * 255).toString(16);
if (r.length == 1)
r = "0" + r;
if (g.length == 1)
g = "0" + g;
if (b.length == 1)
b = "0" + b;
if (a.length == 1)
a = "0" + a;
return "#" + r + g + b + a;
}
describe('Check CSS', function() {
it('should check css of login page', async function(){
browser.waitForAngularEnabled(true);
browser.actions().mouseMove(element(by.css('.btn-auth, .btn-auth:hover'))).perform(); // mouse hover on button
csspage.Loc_auth_btn.getCssValue('color').then(function(color){
console.log(RGBAToHexA(color))
expect( RGBAToHexA(color)).toContain(cssData.hoverauth.color);
})
Works the best. If you want to use it sitewide, without having to add this syntax to every class or ID, add the following CSS to your css body:
body {
-webkit-font-smoothing: antialiased;
text-shadow: 1px 1px 1px rgba(0,0,0,0.004);
background: url('./images/background.png');
text-align: left;
margin: auto;
}
Although you should not use doubles for precise calculations the following trick helped me if you are rounding the results anyway.
public static int round(Double i) {
return (int) Math.round(i + ((i > 0.0) ? 0.00000001 : -0.00000001));
}
Example:
Double foo = 0.0;
for (int i = 1; i <= 150; i++) {
foo += 0.00010;
}
System.out.println(foo);
System.out.println(Math.round(foo * 100.0) / 100.0);
System.out.println(round(foo*100.0) / 100.0);
Which prints:
0.014999999999999965
0.01
0.02
With the release of Java 5, the product version was made distinct from the developer version as described here
For completeness/interest I'd like to add that matlab does have a function that allows you to operate on data per-row rather than per-element. It is called rowfun
(http://www.mathworks.se/help/matlab/ref/rowfun.html), but the only "problem" is that it operates on tables (http://www.mathworks.se/help/matlab/ref/table.html) rather than matrices.
Here's one view on the singleton methods:
I have found these various "singleton" methods to be useful for passing a single value to an API that requires a collection of that value. Of course, this works best when the code processing the passed-in value does not need to add to the collection.
On windows use the name of the table in quotes:
TABLE "user";
or SELECT * FROM "user";
You could use a labeled BREAK statement:
search:
for (i = 0; i < arrayOfInts.length; i++) {
for (j = 0; j < arrayOfInts[i].length; j++) {
if (arrayOfInts[i][j] == searchfor) {
foundIt = true;
break search;
}
}
}
However, in properly designed code, you shouldn't need GOTO functionality.
I had a similar error, but it was because I had created a has_one
relationship and subsequently deleted the model that it had_one
of. I just forgot to delete the has_one
relationship from the remaining model.
Here is another solution considering all columns (more compact way of J.J's answer);
ar=np.array([[0, 0, 0, 1],
[1, 0, 1, 0],
[0, 1, 0, 0],
[1, 0, 0, 1],
[0, 0, 1, 0],
[1, 1, 0, 0]])
Sort with lexsort,
ar[np.lexsort(([ar[:, i] for i in range(ar.shape[1]-1, -1, -1)]))]
Output:
array([[0, 0, 0, 1],
[0, 0, 1, 0],
[0, 1, 0, 0],
[1, 0, 0, 1],
[1, 0, 1, 0],
[1, 1, 0, 0]])
db:create
- Creates the database for the current RAILS_ENV environment. If RAILS_ENV is not specified it defaults to the development and test databases.
db:create:all
- Creates the database for all environments.
db:drop
- Drops the database for the current RAILS_ENV environment. If RAILS_ENV is not specified it defaults to the development and test databases.
db:drop:all
- Drops the database for all environments.
db:migrate
- Runs migrations for the current environment that have not run yet. By default it will run migrations only in the development environment.
db:migrate:redo
- Runs db:migrate:down and db:migrate:up or db:migrate:rollback and db:migrate:up depending on the specified migration.
db:migrate:up
- Runs the up for the given migration VERSION.
db:migrate:down
- Runs the down for the given migration VERSION.
db:migrate:status
- Displays the current migration status.
db:migrate:rollback
- Rolls back the last migration.
db:version
- Prints the current schema version.
db:forward
- Pushes the schema to the next version.
db:seed
- Runs the db/seeds.rb file.
db:schema:load
Recreates the database from the schema.rb file. Deletes existing data.
db:schema:dump
Dumps the current environment’s schema to db/schema.rb.
db:structure:load
- Recreates the database from the structure.sql file.
db:structure:dump
- Dumps the current environment’s schema to db/structure.sql.
(You can specify another file with SCHEMA=db/my_structure.sql
)
db:setup
Runs db:create, db:schema:load and db:seed.
db:reset
Runs db:drop and db:setup.
db:migrate:reset
- Runs db:drop, db:create and db:migrate.
db:test:prepare
- Check for pending migrations and load the test schema. (If you run rake without any arguments it will do this by default.)
db:test:clone
- Recreate the test database from the current environment’s database schema.
db:test:clone_structure
- Similar to db:test:clone, but it will ensure that your test database has the same structure, including charsets and collations, as your current environment’s database.
db:environment:set
- Set the current RAILS_ENV environment in the ar_internal_metadata table. (Used as part of the protected environment check.)
db:check_protected_environments
- Checks if a destructive action can be performed in the current RAILS_ENV environment. Used internally when running a destructive action such as db:drop or db:schema:load.
In C, it is a common idiom to zero out the memory for a struct
using memset
:
struct x myStruct;
memset(&myStruct, 0, sizeof(myStruct));
Technically speaking, I don't believe that this is portable because it assumes that the NULL
pointer on a machine is represented by the integer value 0, but it's used widely because on most machines this is the case.
If you move from C to C++, be careful not to use this technique on every object. C++ only makes this legal on objects with no member functions and no inheritance.
From the documentation of InetAddress.getByName(String host)
:
The host name can either be a machine name, such as "java.sun.com", or a textual representation of its IP address. If a literal IP address is supplied, only the validity of the address format is checked.
So you can use it.
It's already 2019, I can't believe still no easiest and conveniencest way to convert the most popular Micro$oft Word document to Adobe PDF format in Java world.
I almost tried every method the above answers mentioned, and I found the best and the only way can satisfy my requirement is by using OpenOffice or LibreOffice. Actually I am not exactly know the difference between them, seems both of them provide soffice
command line.
My requirement is:
First thing came in mind is doc-to-pdf-converter
, but it lacks of maintenance, last update happened 4 years ago, I will not use a nobody-maintain-solution. Xdocreport
seems a promising choice, but it can only convert docx
, but not doc
binary file which is mandatory for me. Using Java to call OpenOffice API seems good, but too complicated for such a simple requirement.
Finally I found the best solution: use OpenOffice command line to finish the job:
Runtime.getRuntime().exec("soffice --convert-to pdf -outdir . /path/some.doc");
I always believe the shortest code is the best code (of course it should be understandable), that's it.
Create the hash:
hash = {:item1 => 1}
Add a new item to it:
hash[:item2] = 2
There's a handy .NET method for that:
C:\PS> [io.path]::GetFileNameWithoutExtension("c:\temp\myfile.txt")
myfile
KOTLIN
There is also the possibility to use sufficientlysecure.htmltextview.HtmlTextView
Use like below in gradle files:
Project gradle file:
repositories {
jcenter()
}
App gradle file:
dependencies {
implementation 'org.sufficientlysecure:html-textview:3.9'
}
Inside xml file replace your textView with:
<org.sufficientlysecure.htmltextview.HtmlTextView
android:id="@+id/allNewsBlockTextView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="2dp"
android:textColor="#000"
android:textSize="18sp"
app:htmlToString="@{detailsViewModel.selectedText}" />
Last line above is if you use Binding adapters where the code will be like:
@BindingAdapter("htmlToString")
fun bindTextViewHtml(textView: HtmlTextView, htmlValue: String) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
textView.setHtml(
htmlValue,
HtmlHttpImageGetter(textView, "n", true)
);
} else {
textView.setHtml(
htmlValue,
HtmlHttpImageGetter(textView, "n", true)
);
}
}
More info from github page and a big thank you to the authors!!!!!
Here's how you do it for SQL Server. Someone else can translate it to MySQL. Parsing CSV Values Into Multiple Rows.
SELECT Author,
NullIf(SubString(',' + Phrase + ',' , ID , CharIndex(',' , ',' + Phrase + ',' , ID) - ID) , '') AS Word
FROM Tally, Quotes
WHERE ID <= Len(',' + Phrase + ',') AND SubString(',' + Phrase + ',' , ID - 1, 1) = ','
AND CharIndex(',' , ',' + Phrase + ',' , ID) - ID > 0
The idea is to cross join to a predefined table Tally which contains integer 1 through 8000 (or whatever big enough number) and run SubString
to find the right ,word, position.
Just Download mysqlclient from here https://www.lfd.uci.edu/~gohlke/pythonlibs/ be careful while downloading the right version depending on your your python version installed. Then proceed with the import. It worked for me because in my case the error was telling to install Visual Studio C++ 14.0 something which wasted my time and occupied around 10GB of space in my C drive. So recommending installing mysqlclient using pip install mysqlclient
/* worked for me */

You can use ax.figure.savefig()
:
import pandas as pd
s = pd.Series([0, 1])
ax = s.plot.hist()
ax.figure.savefig('demo-file.pdf')
This has no practical benefit over ax.get_figure().savefig()
as suggested in Philip Cloud's answer, so you can pick the option you find the most aesthetically pleasing. In fact, get_figure()
simply returns self.figure
:
# Source from snippet linked above
def get_figure(self):
"""Return the `.Figure` instance the artist belongs to."""
return self.figure
in build.gradle:
compile 'com.google.maps.android:android-maps-utils:0.4'
and then:
public static Double distanceBetween(LatLng point1, LatLng point2) {
if (point1 == null || point2 == null) {
return null;
}
return SphericalUtil.computeDistanceBetween(point1, point2);
}
This should work:
ax1.plot(xtr, color='r', label='HHZ 1')
ax1.legend(loc="upper right")
ax2.plot(xtr, color='r', label='HHN')
ax2.legend(loc="upper right")
ax3.plot(xtr, color='r', label='HHE')
ax3.legend(loc="upper right")
Note that the if $myVar; then ... ;fi
construct has a security problem you might want to avoid with
case $myvar in
(true) echo "is true";;
(false) echo "is false";;
(rm -rf*) echo "I just dodged a bullet";;
esac
You might also want to rethink why if [ "$myvar" = "true" ]
appears awkward to you. It's a shell string comparison that beats possibly forking a process just to obtain an exit status. A fork is a heavy and expensive operation, while a string comparison is dead cheap. Think a few CPU cycles versus several thousand. My case
solution is also handled without forks.

I will suggest you not to really depend of database for translation it could be really a messy task and could be a extreme problem in case of data encoding.
I had face similar issue while ago and written following class to solve my problem
<?php

geoip
is installed then it will return country code by geoip_country_code_by_name
and if geoip is not installed the fallback to HTTP_ACCEPT_LANGUAGE
headerIn case anyone is looking for a solution without code, I created an example to do this completely in the storyboard, using Auto Layout.
You can get it from github.
Basically, to recreate the example (for vertical scrolling):
UIScrollView
, and set its constraints.UIStackView
to the UIScrollView
Leading
, Trailing
, Top
& Bottom
should be equal to the ones from UIScrollView
Width
constraint between the UIStackView
and UIScrollView
. UIStackView
UIViews
to the UIStackView
Exchange Width
for Height
in step 4, and set Axis
= Horizontal
in step 5, to get a horizontal UIStackView.
The suggestion from @Dawood is good if that works for you.
If you need more fine-tuning than that, one option is to use padding on the text elements, here's an example: http://jsfiddle.net/panchroma/FtBwe/
CSS
p, h2 {
padding-left:10px;
}
Cloudera and Hortonworks are the best tools to start up with the HDFS in Microsoft Windows. You can also use VMWare or VBox to initiate Virtual Machine to establish build to your HDFS and Spark, Hive, HBase, Pig, Hadoop with Scala, R, Java, Python.
Using pathlib you can get the folder in which the current file is located. __file__
is the pathname of the file from which the module was loaded.
Ref: docs
import pathlib
current_dir = pathlib.Path(__file__).parent
current_file = pathlib.Path(__file__)

It's still not going to do what you want; you have more bugs, like trying to unpack a 3-dimensional shape into two target variables in test
.
Sorry to wake the dead, but I thought someone might find this useful for future reference.
Here is how I handle it. It handles floating point numbers, but can easily be modified for integers.
Basically you can only press 0 - 9 and .
You can only have one 0 before the .
All other characters are ignored and the cursor position maintained.
private bool _myTextBoxChanging = false;
private void myTextBox_TextChanged(object sender, EventArgs e)
{
validateText(myTextBox);
}
private void validateText(TextBox box)
{
// stop multiple changes;
if (_myTextBoxChanging)
return;
_myTextBoxChanging = true;
string text = box.Text;
if (text == "")
return;
string validText = "";
bool hasPeriod = false;
int pos = box.SelectionStart;
for (int i = 0; i < text.Length; i++ )
{
bool badChar = false;
char s = text[i];
if (s == '.')
{
if (hasPeriod)
badChar = true;
else
hasPeriod = true;
}
else if (s < '0' || s > '9')
badChar = true;
if (!badChar)
validText += s;
else
{
if (i <= pos)
pos--;
}
}
// trim starting 00s
while (validText.Length >= 2 && validText[0] == '0')
{
if (validText[1] != '.')
{
validText = validText.Substring(1);
if (pos < 2)
pos--;
}
else
break;
}
if (pos > validText.Length)
pos = validText.Length;
box.Text = validText;
box.SelectionStart = pos;
_myTextBoxChanging = false;
}
Here is a quickly modified int version:
private void validateText(TextBox box)
{
// stop multiple changes;
if (_myTextBoxChanging)
return;
_myTextBoxChanging = true;
string text = box.Text;
if (text == "")
return;
string validText = "";
int pos = box.SelectionStart;
for (int i = 0; i < text.Length; i++ )
{
char s = text[i];
if (s < '0' || s > '9')
{
if (i <= pos)
pos--;
}
else
validText += s;
}
// trim starting 00s
while (validText.Length >= 2 && validText.StartsWith("00"))
{
validText = validText.Substring(1);
if (pos < 2)
pos--;
}
if (pos > validText.Length)
pos = validText.Length;
box.Text = validText;
box.SelectionStart = pos;
_myTextBoxChanging = false;
}
If you prefer immutable data objects, or if you just dont want to be destructive to the input list, you can use Guava's predicates.
ImmutableList.copyOf(Iterables.filter(tourists, Predicates.notNull()))
I have a similar table styled like so:
<table style="width:100%; table-layout:fixed">

<td style="width: 150px">Hello, World!</td>
<td>
<div>
<pre style="margin:0; overflow:scroll">My preformatted content</pre>
</div>
</td>
</tr>
</table>
for
-loopA traditional for
-loop has three components :
These three components are seperated from each other by a ;
symbol. Content for each of these three components is optional, which means that the following is the most minimal for
-loop possible :
for (;;) {
// Do stuff
}
Of course, you will need to include an if(condition === true) { break; }
or an if(condition === true) { return; }
somewhere inside that for
-loop to get it to stop running.
Usually, though, the initialization is used to declare an index, the condition is used to compare that index with a minimum or maximum value, and the afterthought is used to increment the index :
for (var i = 0, length = 10; i < length; i++) {
console.log(i);
}
for
-loop to loop through an arrayThe traditional way to loop through an array, is this :
for (var i = 0, length = myArray.length; i < length; i++) {
console.log(myArray[i]);
}
Or, if you prefer to loop backwards, you do this :
for (var i = myArray.length - 1; i > -1; i--) {
console.log(myArray[i]);
}
There are, however, many variations possible, like eg. this one :
for (var key = 0, value = myArray[key], var length = myArray.length; key < length; value = myArray[++key]) {
console.log(value);
}
... or this one ...
var i = 0, length = myArray.length;
for (; i < length;) {
console.log(myArray[i]);
i++;
}
... or this one :
var key = 0, value;
for (; value = myArray[key++];){
console.log(value);
}
Whichever works best is largely a matter of both personal taste and the specific use case you're implementing.
Note :Each of these variations is supported by all browsers, including véry old ones!
while
-loopOne alternative to a for
-loop is a while
-loop. To loop through an array, you could do this :
var key = 0;
while(value = myArray[key++]){
console.log(value);
}
Note :
Like traditional for
-loops, while
-loops are supported by even the oldest of browsers.
Also, every while loop can be rewritten as a for
-loop. For example, the while
-loop hereabove behaves the exact same way as this for
-loop :
for(var key = 0;value = myArray[key++];){
console.log(value);
}
for...in
and for...of
In JavaScript, you can also do this :
for (i in myArray) {
console.log(myArray[i]);
}
This should be used with care, however, as it doesn't behave the same as a traditonal for
-loop in all cases, and there are potential side-effects that need to be considered. See Why is using "for...in" with array iteration a bad idea? for more details.
As an alternative to for...in
, there's now also for for...of
. The following example shows the difference between a for...of
loop and a for...in
loop :
var myArray = [3, 5, 7];
myArray.foo = "hello";
for (var i in myArray) {
console.log(i); // logs 0, 1, 2, "foo"
}
for (var i of myArray) {
console.log(i); // logs 3, 5, 7
}
Note :
You also need to consider that no version of Internet Explorer supports for...of
(Edge 12+ does) and that for...in
requires at least IE10.
Array.prototype.forEach()
An alternative to For
-loops is Array.prototype.forEach()
, which uses the following syntax :
myArray.forEach(function(value, key, myArray) {
console.log(value);
});
Note :
Array.prototype.forEach()
is supported by all modern browsers, as well as IE9+.
jQuery.each()
Additionally to the four other options mentioned, jQuery also had its own foreach
variation.
It uses the following syntax :
$.each(myArray, function(key, value) {
console.log(value);
});
If you don't want to use dangerouslySetInnerHTML then you can use the below mentioned solution
var Iframe = React.createClass({
render: function() {
return(
<div>
<iframe src={this.props.src} height={this.props.height} width={this.props.width}/>
</div>
)
}
});
ReactDOM.render(
<Iframe src="http://plnkr.co/" height="500" width="500"/>,
document.getElementById('example')
);

In CSS2.1, an element can only have at most one of any kind of pseudo-element at any time. (This means an element can have both a :before
and an :after
pseudo-element — it just cannot have more than one of each kind.)
As a result, when you have multiple :before
rules matching the same element, they will all cascade and apply to a single :before
pseudo-element, as with a normal element. In your example, the end result looks like this:
.circle.now:before {
content: "Now";
font-size: 19px;
color: black;
}
As you can see, only the content
declaration that has highest precedence (as mentioned, the one that comes last) will take effect — the rest of the declarations are discarded, as is the case with any other CSS property.
This behavior is described in the Selectors section of CSS2.1:
Pseudo-elements behave just like real elements in CSS with the exceptions described below and elsewhere.
This implies that selectors with pseudo-elements work just like selectors for normal elements. It also means the cascade should work the same way. Strangely, CSS2.1 appears to be the only reference; neither css3-selectors nor css3-cascade mention this at all, and it remains to be seen whether it will be clarified in a future specification.
If an element can match more than one selector with the same pseudo-element, and you want all of them to apply somehow, you will need to create additional CSS rules with combined selectors so that you can specify exactly what the browser should do in those cases. I can't provide a complete example including the content
property here, since it's not clear for instance whether the symbol or the text should come first. But the selector you need for this combined rule is either .circle.now:before
or .now.circle:before
— whichever selector you choose is personal preference as both selectors are equivalent, it's only the value of the content
property that you will need to define yourself.
If you still need a concrete example, see my answer to this similar question.
The legacy css3-content specification contains a section on inserting multiple ::before
and ::after
pseudo-elements using a notation that's compatible with the CSS2.1 cascade, but note that that particular document is obsolete — it hasn't been updated since 2003, and no one has implemented that feature in the past decade. The good news is that the abandoned document is actively undergoing a rewrite in the guise of css-content-3 and css-pseudo-4. The bad news is that the multiple pseudo-elements feature is nowhere to be found in either specification, presumably owing, again, to lack of implementer interest.
wget is capable of doing what you are asking. Just try the following:
wget -p -k http://www.example.com/
The -p
will get you all the required elements to view the site correctly (css, images, etc).
The -k
will change all links (to include those for CSS & images) to allow you to view the page offline as it appeared online.
From the Wget docs:
‘-k’
‘--convert-links’
After the download is complete, convert the links in the document to make them
suitable for local viewing. This affects not only the visible hyperlinks, but
any part of the document that links to external content, such as embedded images,
links to style sheets, hyperlinks to non-html content, etc.
Each link will be changed in one of the two ways:
The links to files that have been downloaded by Wget will be changed to refer
to the file they point to as a relative link.
Example: if the downloaded file /foo/doc.html links to /bar/img.gif, also
downloaded, then the link in doc.html will be modified to point to
‘../bar/img.gif’. This kind of transformation works reliably for arbitrary
combinations of directories.
The links to files that have not been downloaded by Wget will be changed to
include host name and absolute path of the location they point to.
Example: if the downloaded file /foo/doc.html links to /bar/img.gif (or to
../bar/img.gif), then the link in doc.html will be modified to point to
http://hostname/bar/img.gif.
Because of this, local browsing works reliably: if a linked file was downloaded,
the link will refer to its local name; if it was not downloaded, the link will
refer to its full Internet address rather than presenting a broken link. The fact
that the former links are converted to relative links ensures that you can move
the downloaded hierarchy to another directory.
Note that only at the end of the download can Wget know which links have been
downloaded. Because of that, the work done by ‘-k’ will be performed at the end
of all the downloads.
This question is already answered, but for the benefit of others looking at this question I'd like to add the following suggestion: Instead of doing the slicing yourself as suggested above you might also use strptime()
which is (IMHO) easier to read and perhaps the preferred way to do this conversion.
import datetime
s = "20120213"
s_datetime = datetime.datetime.strptime(s, '%Y%m%d')
If you want to escape from Form Freeze and use editing (like text for a button) use this code
Form form = new Form();
Form.Button.Text = "randomText";
System.Windows.Forms.Application.EnableVisualStyles();
System.Windows.Forms.Application.Run(form);
Here's another straightforward alternative.
> which(strsplit(string, "")[[1]]=="2")
[1] 4 24
Can you check value of i
by putting logger or println(). and check with closing db conn at the end. Rest your code looks fine and it should work.
If you want to access the variables some sort of dynamic you may use reflection. However Reflection works not for local variables. It is only applyable for class attributes.
A rough quick and dirty example is this:
public class T {
public Integer n1;
public Integer n2;
public Integer n3;
public void accessAttributes() throws IllegalArgumentException, SecurityException, IllegalAccessException,
NoSuchFieldException {
for (int i = 1; i < 4; i++) {
T.class.getField("n" + i).set(this, 5);
}
}
}
You need to improve this code in various ways it is only an example. This is also not considered to be good code.
extension String {
var lowercased:String {
var result = Array<Character>(self.characters);
if let first = result.first { result[0] = Character(String(first).uppercaseString) }
return String(result)
}
}
Make sure that the column values u added in entity class having get set properties also in the same order which is present in target table.
ExecuteNonQuery method will return number of rows effected with INSERT, DELETE or UPDATE operations. This ExecuteNonQuery method will be used only for insert, update and delete, Create, and SET statements. (Read More)
ExecuteScalar will return single row single column value i.e. single value, on execution of SQL Query or Stored procedure using command object. It’s very fast to retrieve single values from database. (Read More)
ExecuteReader will be used to return the set of rows, on execution of SQL Query or Stored procedure using command object. This one is forward only retrieval of records and it is used to read the table values from first to last. (Read More)
The let
keyword defines a constant:
let theAnswer = 42
The theAnswer
cannot be changed afterwards. This is why anything weak
can't be written using let
. They need to change during runtime and you must be using var
instead.
The var
defines an ordinary variable.
What is interesting:
The value of a constant doesn’t need to be known at compile time, but you must assign the value exactly once.
Another strange feature:
You can use almost any character you like for constant and variable names, including Unicode characters:
let = "dogcow"

You could use flatMap. It can filter and map in one.
$scope.appIds = $scope.applicationsHere.flatMap(obj => obj.selected ? obj.id : [])
I have a feeling that the username and password that you are sending should be part of the Authorization Header. So the code below shows you how to create the Base64 string of the username and password. I also included an example of sending the POST data. In my case it was a phone_number parameter.
string credentials = Convert.ToBase64String(Encoding.ASCII.GetBytes(_username + ":" + _password));
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(Request);
webRequest.Headers.Add("Authorization", string.Format("Basic {0}", credentials));
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.Method = WebRequestMethods.Http.Post;
webRequest.AllowAutoRedirect = true;
webRequest.Proxy = null;
string data = "phone_number=19735559042";
byte[] dataStream = Encoding.UTF8.GetBytes(data);
request.ContentLength = dataStream.Length;
Stream newStream = webRequest.GetRequestStream();
newStream.Write(dataStream, 0, dataStream.Length);
newStream.Close();
HttpWebResponse response = (HttpWebResponse)webRequest.GetResponse();
Stream stream = response.GetResponseStream();
StreamReader streamreader = new StreamReader(stream);
string s = streamreader.ReadToEnd();
truncate without zeroes
function toTrunc(value,n){
return Math.floor(value*Math.pow(10,n))/(Math.pow(10,n));
}
or
function toTrunc(value,n){
x=(value.toString()+".0").split(".");
return parseFloat(x[0]+"."+x[1].substr(0,n));
}
test:
toTrunc(17.4532,2) //17.45
toTrunc(177.4532,1) //177.4
toTrunc(1.4532,1) //1.4
toTrunc(.4,2) //0.4
truncate with zeroes
function toTruncFixed(value,n){
return toTrunc(value,n).toFixed(n);
}
test:
toTrunc(17.4532,2) //17.45
toTrunc(177.4532,1) //177.4
toTrunc(1.4532,1) //1.4
toTrunc(.4,2) //0.40
Make sure that your sas.png
is marked as Build Action: Content
and Copy To Output Directory: Copy Always
in its Visual Studio Properties
...
I think the C# source code goes like this...
Image image = new Image();
image.Source = (new ImageSourceConverter()).ConvertFromString("pack://application:,,,/Bilder/sas.png") as ImageSource;
and XAML should be
<Image Height="200" HorizontalAlignment="Left" Margin="12,12,0,0"
Name="image1" Stretch="Fill" VerticalAlignment="Top"
Source="../Bilder/sas.png"
Width="350" />
EDIT
Dynamically I think XAML would provide best way to load Images ...
<Image Source="{Binding Converter={StaticResource MyImageSourceConverter}}"
x:Name="MyImage"/>
where image.DataContext
is string
path.
MyImage.DataContext = "pack://application:,,,/Bilder/sas.png";
public class MyImageSourceConverter : IValueConverter
{
public object Convert(object value_, Type targetType_,
object parameter_, System.Globalization.CultureInfo culture_)
{
return (new ImageSourceConverter()).ConvertFromString (value.ToString());
}
public object ConvertBack(object value, Type targetType,
object parameter, CultureInfo culture)
{
throw new NotImplementedException();
}
}
Now as you set a different data context, Image
would be automatically loaded at runtime.
For what it's worth, a Dictionary is (conceptually) a hash table.
If you meant "why do we use the Dictionary<TKey, TValue>
class instead of the Hashtable
class?", then it's an easy answer: Dictionary<TKey, TValue>
is a generic type, Hashtable
is not. That means you get type safety with Dictionary<TKey, TValue>
, because you can't insert any random object into it, and you don't have to cast the values you take out.
Interestingly, the Dictionary<TKey, TValue>
implementation in the .NET Framework is based on the Hashtable
, as you can tell from this comment in its source code:
The generic Dictionary was copied from Hashtable's source
in angular2 2.1.1 I was not able to catch the exception using the (data),(error) pattern, so I implemented it using .catch(...).
It's nice because it can be used with all other Observable chained methods like .retry .map etc.
import {Observable} from 'rxjs/Rx';
Http
.put(...)
.catch(err => {
notify('UI error handling');
return Observable.throw(err); // observable needs to be returned or exception raised
})
.subscribe(data => ...) // handle success
from documentation:
Returns
(Observable): An observable sequence containing elements from consecutive source sequences until a source sequence terminates successfully.
In case your appserver is WebLogic (for me it was 10.3.6) then properties responsible for timeouts are:
com.sun.xml.ws.connect.timeout
com.sun.xml.ws.request.timeout
BaileyP's answer is already pretty good, but I would use this condition instead:
if(function_exists('get_magic_quotes_gpc') && get_magic_quotes_gpc() === 1){
$_POST = array_map( 'stripslashes', $_POST );
$_GET = array_map( 'stripslashes', $_GET );
$_COOKIE = array_map( 'stripslashes', $_COOKIE );
}
It is more defensive.
You may want to have a look at https://isocpp.org/wiki/faq/pointers-to-members#fnptr-vs-memfnptr-types, especially [33.1] Is the type of "pointer-to-member-function" different from "pointer-to-function"?
It is highly unlikely that adding NameVirtualHost *:443
is the right solution, because there are a limited number of situations in which it is possible to support name-based virtual hosts over SSL. Read this and this for some details (there may be better docs out there; these were just ones I found that discuss the issue in detail).
If you're running a relatively stock Apache configuration, you probably have this somewhere:
<VirtualHost _default_:443>
Your best bet is to either:
VirtualHost
container, or VirtualHost
block and create a new one. Don't forget to include all the relevant SSL options.In case you already have d3.js as a dependency in your project, or don't mind bringing it in, d3-time (d3.js library is modular as of v4.0.0) has got Intervals.
They might prove useful when setting dates to "default" values, e.g. midnight, 0.00 seconds, the first of the month, etc.
var d = new Date(); // Wed Aug 02 2017 15:01:07 GMT+0200 (CEST)
d3.timeHour(d) // Wed Aug 02 2017 00:00:00 GMT+0200 (CEST)
d3.timeMonth(d) // Tue Aug 01 2017 00:00:00 GMT+0200 (CEST)
With dplyr 0.7.2
, you can use the very useful case_when
function :
x=read.table(
text="V1 V2 V3 V4
1 1 2 3 5
2 2 4 4 1
3 1 4 1 1
4 4 5 1 3
5 5 5 5 4")
x$V5 = case_when(x$V1==1 & x$V2!=4 ~ 1,
x$V2==4 & x$V3!=1 ~ 2,
TRUE ~ 0)
Expressed with dplyr::mutate
, it gives:
x = x %>% mutate(
V5 = case_when(
V1==1 & V2!=4 ~ 1,
V2==4 & V3!=1 ~ 2,
TRUE ~ 0
)
)
Please note that NA
are not treated specially, as it can be misleading. The function will return NA
only when no condition is matched. If you put a line with TRUE ~ ...
, like I did in my example, the return value will then never be NA
.
Therefore, you have to expressively tell case_when
to put NA
where it belongs by adding a statement like is.na(x$V1) | is.na(x$V3) ~ NA_integer_
. Hint: the dplyr::coalesce()
function can be really useful here sometimes!
Moreover, please note that NA
alone will usually not work, you have to put special NA
values : NA_integer_
, NA_character_
or NA_real_
.
Update your remote if you still haven't done so:
$ git remote update
$ git branch -r
I have an utility method to switch to the required window as shown below
public class Utility
{
public static WebDriver getHandleToWindow(String title){
//parentWindowHandle = WebDriverInitialize.getDriver().getWindowHandle(); // save the current window handle.
WebDriver popup = null;
Set<String> windowIterator = WebDriverInitialize.getDriver().getWindowHandles();
System.err.println("No of windows : " + windowIterator.size());
for (String s : windowIterator) {
String windowHandle = s;
popup = WebDriverInitialize.getDriver().switchTo().window(windowHandle);
System.out.println("Window Title : " + popup.getTitle());
System.out.println("Window Url : " + popup.getCurrentUrl());
if (popup.getTitle().equals(title) ){
System.out.println("Selected Window Title : " + popup.getTitle());
return popup;
}
}
System.out.println("Window Title :" + popup.getTitle());
System.out.println();
return popup;
}
}
It will take you to desired window once title of the window is passed as parameter. In your case you can do.
Webdriver childDriver = Utility.getHandleToWindow("titleOfChildWindow");
and then again switch to parent window using the same method
Webdriver parentDriver = Utility.getHandleToWindow("titleOfParentWindow");
This method works effectively when dealing with multiple windows.
Here is the OOP way of adding a colorbar:
fig, ax = plt.subplots()
im = ax.scatter(x, y, c=c)
fig.colorbar(im, ax=ax)
An implementation of left outer join by extension methods could look like
public static IEnumerable<Result> LeftJoin<TOuter, TInner, TKey, Result>(
this IEnumerable<TOuter> outer, IEnumerable<TInner> inner
, Func<TOuter, TKey> outerKeySelector, Func<TInner, TKey> innerKeySelector
, Func<TOuter, TInner, Result> resultSelector, IEqualityComparer<TKey> comparer)
{
if (outer == null)
throw new ArgumentException("outer");
if (inner == null)
throw new ArgumentException("inner");
if (outerKeySelector == null)
throw new ArgumentException("outerKeySelector");
if (innerKeySelector == null)
throw new ArgumentException("innerKeySelector");
if (resultSelector == null)
throw new ArgumentException("resultSelector");
return LeftJoinImpl(outer, inner, outerKeySelector, innerKeySelector, resultSelector, comparer ?? EqualityComparer<TKey>.Default);
}
static IEnumerable<Result> LeftJoinImpl<TOuter, TInner, TKey, Result>(
IEnumerable<TOuter> outer, IEnumerable<TInner> inner
, Func<TOuter, TKey> outerKeySelector, Func<TInner, TKey> innerKeySelector
, Func<TOuter, TInner, Result> resultSelector, IEqualityComparer<TKey> comparer)
{
var innerLookup = inner.ToLookup(innerKeySelector, comparer);
foreach (var outerElment in outer)
{
var outerKey = outerKeySelector(outerElment);
var innerElements = innerLookup[outerKey];
if (innerElements.Any())
foreach (var innerElement in innerElements)
yield return resultSelector(outerElment, innerElement);
else
yield return resultSelector(outerElment, default(TInner));
}
}
The resultselector then has to take care of the null elements. Fx.
static void Main(string[] args)
{
var inner = new[] { Tuple.Create(1, "1"), Tuple.Create(2, "2"), Tuple.Create(3, "3") };
var outer = new[] { Tuple.Create(1, "11"), Tuple.Create(2, "22") };
var res = outer.LeftJoin(inner, item => item.Item1, item => item.Item1, (it1, it2) =>
new { Key = it1.Item1, V1 = it1.Item2, V2 = it2 != null ? it2.Item2 : default(string) });
foreach (var item in res)
Console.WriteLine(string.Format("{0}, {1}, {2}", item.Key, item.V1, item.V2));
}
.NET Core is the current version of .NET that you should be using right now (more features , fixed bugs , etc.)
Xamarin is a platform that provides solutions for cross platform mobile problems coded in C# , so that you don't need to use Swift separately for IOS and the same goes for Android.
If I understood you right, you mean that if you have a function 'func', you want to check for each item in list if func(item) returns true; if you get true for all, then do something.
You can use 'all'.
For example: I want to get all prime numbers in range 0-10 in a list:
from math import sqrt
primes = [x for x in range(10) if x > 2 and all(x % i !=0 for i in range(2, int(sqrt(x)) + 1))]
My solution for changing seconds (number) to string format (for example: 'mm:ss'):
const formattedSeconds = moment().startOf('day').seconds(S).format('mm:ss');
Write your seconds instead 'S' in example. And just use the 'formattedSeconds' where you need.
In my case the problem was that many scikit functions return numpy arrays, which are devoid of pandas index. So there was an index mismatch when I used those numpy arrays to build new DataFrames and then I tried to mix them with the original data.
Vartec's answer with cURL didn't work for me. It did, with a slight improvement due to my specific problem.
e.g.,
When there is a redirect on the server (like when you are trying to save the facebook profile image) you will need following option set:
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
The full solution becomes:
$ch = curl_init('http://example.com/image.php');
$fp = fopen('/my/folder/flower.gif', 'wb');
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_exec($ch);
curl_close($ch);
fclose($fp);
include math.h and compile with gcc test.c -lm
In my case Tomcat was running in a background. I've installed it as a external servlet while using Eclipse.
With a Spring Boot in Intellij it has it own server but cannot start while it's already occupied.
In my case Tomcat starts automatically I turn on my OS, that is why I need to shut down him manualy:
$ sudo service tomcat stop
of course "tomcat" depends what version of tomcat you are using.
Hope it might help to someone.
You get the warning because you did not assign a value to one
, which is a pointer. This is undefined behavior.
You should declare it like this:
Vector* one = malloc(sizeof(Vector));
or like this:
Vector one;
in which case you need to replace ->
operator with .
like this:
one.a = 12;
one.b = 13;
one.c = -11;
Finally, in C99 and later you can use designated initializers:
Vector one = {
.a = 12
, .b = 13
, .c = -11
};
In Apache commons lang, DateUtils class we have a method called parseDate. We can use this for parsing the date.
Also another library Joda-time also have the method to parse the date.
AssemblyVersion
Where other assemblies that reference your assembly will look. If this number changes, other assemblies have to update their references to your assembly! Only update this version, if it breaks backward compatibility. The AssemblyVersion
is required.
I use the format: major.minor. This would result in:
[assembly: AssemblyVersion("1.0")]
If you're following SemVer strictly then this means you only update when the major changes, so 1.0, 2.0, 3.0, etc.
AssemblyFileVersion
Used for deployment. You can increase this number for every deployment. It is used by setup programs. Use it to mark assemblies that have the same AssemblyVersion
, but are generated from different builds.
In Windows, it can be viewed in the file properties.
The AssemblyFileVersion is optional. If not given, the AssemblyVersion is used.
I use the format: major.minor.patch.build, where I follow SemVer for the first three parts and use the buildnumber of the buildserver for the last part (0 for local build). This would result in:
[assembly: AssemblyFileVersion("1.3.2.254")]
Be aware that System.Version names these parts as major.minor.build.revision
!
AssemblyInformationalVersion
The Product version of the assembly. This is the version you would use when talking to customers or for display on your website. This version can be a string, like '1.0 Release Candidate'.
The AssemblyInformationalVersion
is optional. If not given, the AssemblyFileVersion is used.
I use the format: major.minor[.patch] [revision as string]. This would result in:
[assembly: AssemblyInformationalVersion("1.0 RC1")]
I recently had a need to take this one step further, which was to make the property additions in the dynamic object, dynamic themselves, based on user defined entries. The examples here, and from Microsoft's ExpandoObject documentation, do not specifically address adding properties dynamically, but, can be surmised from how you enumerate and delete properties. Anyhow, I thought this might be helpful to someone. Here is an extremely simplified version of how to add truly dynamic properties to an ExpandoObject (ignoring keyword and other handling):
// my pretend dataset
List<string> fields = new List<string>();
// my 'columns'
fields.Add("this_thing");
fields.Add("that_thing");
fields.Add("the_other");
dynamic exo = new System.Dynamic.ExpandoObject();
foreach (string field in fields)
{
((IDictionary<String, Object>)exo).Add(field, field + "_data");
}
// output - from Json.Net NuGet package
textBox1.Text = Newtonsoft.Json.JsonConvert.SerializeObject(exo);
Many frameworks help handle XSS in various ways. When rolling your own or if there's some XSS concern, we can leverage filter_input_array (available in PHP 5 >= 5.2.0, PHP 7.) I typically will add this snippet to my SessionController, because all calls go through there before any other controller interacts with the data. In this manner, all user input gets sanitized in 1 central location. If this is done at the beginning of a project or before your database is poisoned, you shouldn't have any issues at time of output...stops garbage in, garbage out.
/* Prevent XSS input */
$_GET = filter_input_array(INPUT_GET, FILTER_SANITIZE_STRING);
$_POST = filter_input_array(INPUT_POST, FILTER_SANITIZE_STRING);
/* I prefer not to use $_REQUEST...but for those who do: */
$_REQUEST = (array)$_POST + (array)$_GET + (array)$_REQUEST;
The above will remove ALL HTML & script tags. If you need a solution that allows safe tags, based on a whitelist, check out HTML Purifier.
If your database is already poisoned or you want to deal with XSS at time of output, OWASP recommends creating a custom wrapper function for echo
, and using it EVERYWHERE you output user-supplied values:
//xss mitigation functions
function xssafe($data,$encoding='UTF-8')
{
return htmlspecialchars($data,ENT_QUOTES | ENT_HTML401,$encoding);
}
function xecho($data)
{
echo xssafe($data);
}
To remove the blue overlay on mobiles, you can use one of the following:
-webkit-tap-highlight-color: transparent; /* transparent with keyword */
-webkit-tap-highlight-color: rgba(0,0,0,0); /* transparent with rgba */
-webkit-tap-highlight-color: hsla(0,0,0,0); /* transparent with hsla */
-webkit-tap-highlight-color: #00000000; /* transparent with hex with alpha */
-webkit-tap-highlight-color: #0000; /* transparent with short hex with alpha */
However, unlike other properties, you can't use
-webkit-tap-highlight-color: none; /* none keyword */
In DevTools, this will show up as an 'invalid property value' or something.
To remove the blue/black/orange outline when focused, use this:
:focus {
outline: none; /* no outline - for most browsers */
box-shadow: none; /* no box shadow - for some browsers or if you are using Bootstrap */
}
The reason why I removed the box-shadow
is because Bootsrap (and some browsers) sometimes add it to focused elements, so you can remove it using this.
But if anyone is navigating with a keyboard, they will get very confused indeed, because they rely on this outline to navigate. So you can replace it instead
:focus {
outline: 100px dotted #f0f; /* 100px dotted pink outline */
}
You can target taps on mobile using :hover
or :active
, so you could use those to help, possibly. Or it could get confusing.
Full code:
element {
-webkit-tap-highlight-color: transparent; /* remove tap highlight */
}
element:focus {
outline: none; /* remove outline */
box-shadow: none; /* remove box shadow */
}
Other information:
-webkit-tap-highlight-color
then you should set it to a semi-transparent color so the element underneath doesn't get hidden when tapped-webkit-tap-highlight-color
has not got great browser support and is not standard. You can still use it, but watch out!Try adding JSON.stringify(result)
to convert the JS Object into a JSON string.
From your code I can see you are logging the result in error
which is called if the AJAX request fails, so I'm not sure how you'd go about accessing the id/name/etc. then (you are checking for success inside the error condition!).
Note that if you use Chrome's console you should be able to browse through the object without having to stringify the JSON, which makes it easier to debug.
in my case
@JsonInclude(Include.NON_EMPTY)
made it work.
As Edan Maor explained, the quick and dirty way to do it (for [utc-16] encoded .xml files), which you should not do for the resons Edam Maor explained, can done with the following python 2.7 code in case time constraints do not allow you to learn (propper) XML parses.
Assuming you want to:
It worked in python 2.7 modifying an .xml file named "b.xml" located in folder "a", where "a" was located in the "working folder" of python. It outputs the new modified file as "c.xml" in folder "a", without yielding encoding errors (for me) in further use outside of python 2.7.
pattern = '<Author>'
subst = ' <Author>' + domain + '\\' + user_name + '</Author>'
line_index =0 #set line count to 0 before starting
file = io.open('a/b.xml', 'r', encoding='utf-16')
lines = file.readlines()
outFile = open('a/c.xml', 'w')
for line in lines[0:len(lines)]:
line_index =line_index +1
if line_index == len(lines):
#1. & 2. delete last line and adding another line in its place not writing it
outFile.writelines("Write extra line here" + '\n')
# 4. Close root tag:
outFile.writelines("</phonebook>") # as in:
#http://tizag.com/xmlTutorial/xmldocument.php
else:
#3. Substitue a line if it finds the following substring in a line:
pattern = '<Author>'
subst = ' <Author>' + domain + '\\' + user_name + '</Author>'
if pattern in line:
line = subst
print line
outFile.writelines(line)#just writing/copying all the lines from the original xml except for the last.
You are doing it right. The empty code block is what is causing your issue. It's not the condition structure :)
DECLARE @StartDate AS DATETIME

I'll try to answer all your questions by addressing the larger question: How can I sync data between a webserver and an android app?
Syncing data between your webserver and an android app requires a couple of different components on your android device.
This is how your phone actually stores the data it receives from the webserver. One possible method for accomplishing this is writing your own custom ContentProvider backed by a Sqlite database. A decent tutorial for a content provider can be found here: http://thinkandroid.wordpress.com/2010/01/13/writing-your-own-contentprovider/
A ContentProvider defines a consistent interface to interact with your stored data. It could also allow other applications to interact with your data if you wanted. Behind your ContentProvider could be a Sqlite database, a Cache, or any arbitrary storage mechanism.
While I would certainly recommend using a ContentProvider with a Sqlite database you could use any java based storage mechanism you wanted.
This is the format you use to send the data between your webserver and your android app. The two most popular formats these days are XML and JSON. When choosing your format, you should think about what sort of serialization libraries are available. I know off-hand that there's a fantastic library for json serialization called gson: https://github.com/google/gson, although I'm sure similar libraries exist for XML.
You'll want some sort of asynchronous task which can get new data from your server and refresh the mobile content to reflect the content of the server. You'll also want to notify the server whenever you make local changes to content and want to reflect those changes. Android provides the SyncAdapter pattern as a way to easily solve this pattern. You'll need to register user accounts, and then Android will perform lots of magic for you, and allow you to automatically sync. Here's a good tutorial: http://www.c99.org/2010/01/23/writing-an-android-sync-provider-part-1/
As for how you identify if the records are the same, typically you'll create items with a unique id which you store both on the android device and the server. You can use that to make sure you're referring to the same reference. Furthermore, you can store column attributes like "updated_at" to make sure that you're always getting the freshest data, or you don't accidentally write over newly written data.

java -version
If it gives an output everything should be fine. If you want to develop software you might want to set the PATH.
There is no static Equals
method in the Array
class, so what you are using is actually Object.Equals
, which determines if the two object references point to the same object.
If you want to check if the arrays contains the same items in the same order, you can use the SequenceEquals
extension method:
childe1.SequenceEqual(grandFatherNode)
To use SequenceEquals
with multidimensional arrays, you can use an extension to enumerate them. Here is an extension to enumerate a two dimensional array:
public static IEnumerable<T> Flatten<T>(this T[,] items) {
for (int i = 0; i < items.GetLength(0); i++)
for (int j = 0; j < items.GetLength(1); j++)
yield return items[i, j];
}
Usage:
childe1.Flatten().SequenceEqual(grandFatherNode.Flatten())
If your array has more dimensions than two, you would need an extension that supports that number of dimensions. If the number of dimensions varies, you would need a bit more complex code to loop a variable number of dimensions.
You would of course first make sure that the number of dimensions and the size of the dimensions of the arrays match, before comparing the contents of the arrays.
Turns out that you can use the OfType<T>
method to flatten an array, as RobertS pointed out. Naturally that only works if all the items can actually be cast to the same type, but that is usually the case if you can compare them anyway. Example:
childe1.OfType<Person>().SequenceEqual(grandFatherNode.OfType<Person>())
In PowerShell, you could set the http_proxy and https_proxy environment variables like so:
$env:http_proxy="http://proxy:3128"
$env:https_proxy="http://proxy:3128"
In a generic sense an webservice IS a API over HTTP. They often utilize JSON or XML, but there are some other approaches as well.
I think this sample explains the difference between the styles:
james@bodacious-wired:~$cat test.py
#!/usr/bin/env python

element1 = "Hello"
def __init__(self):
self.element2 = "World"
obj = MyClass()
print dir(MyClass)
print "--"
print dir(obj)
print "--"
print obj.element1
print obj.element2
print MyClass.element1 + " " + MyClass.element2
james@bodacious-wired:~$./test.py
['__doc__', '__init__', '__module__', 'element1']
--
['__doc__', '__init__', '__module__', 'element1', 'element2']
--
Hello World
Hello
Traceback (most recent call last):

AttributeError: class MyClass has no attribute 'element2'
element1 is bound to the class, element2 is bound to an instance of the class.
for (char letter = 'A'; letter <= 'Z'; letter++)
{
Debug.WriteLine(letter);
}
So basic idea is to have a div (with display none) containing items to print. Now on click of a button do not print to entire body but just that particular div. Faced lots of issues while printing a div (part of HTML) using window.print(). Used below method and it works seamlessly in edge, chrome and Mozilla for me, let see if it help you too.
function printDiv(id) {
var contents = document.getElementById(id).innerHTML;
var frame1 = document.createElement('iframe');
frame1.name = "frame1";
frame1.style.position = "absolute";
frame1.style.top = "-1000000px";
document.body.appendChild(frame1);
var frameDoc = frame1.contentWindow ? frame1.contentWindow : frame1.contentDocument.document ? frame1.contentDocument.document : frame1.contentDocument;
frameDoc.document.open();
frameDoc.document.write("<html><head>\n\n " +
"<style type=\"text/css\" media=\"print\">\n " +
"@@page\n {\n " +
"size: auto; /* auto is the initial value */\n " +
"margin: 10mm; /* this affects the margin in the printer settings */\n " +
" }\n\n html\n {\n " +
" background-color: #FFFFFF;\n " +
" }\n\n body\n " +
" { font-family:\"Times New Roman\", Times, serif;\n " +
" border: none ;\n " +
" margin: 0; /* margin you want for the content */\n " +
" }\n .table {\n width: 100%;\n " +
" max-width: 100%;\n margin-bottom: 20px;\n " +
" border-collapse: collapse;\n " +
" background-color: transparent;\n display: table;\n " +
" }\n .table-bordered {\n " +
" border: 1px solid #ccc;\n }\n tr {\n " +
" display: table-row;\n vertical-align: inherit;\n " +
" border-color: inherit;\n padding:15px;\n }\n " +
" .table-bordered tr td {border: 1px solid #ccc!important; padding:15px!important;}\n " +
" </style><title></title></head><body>".concat(contents, "</body>"));
frameDoc.document.close();
setTimeout(function () {
window.frames["frame1"].focus();
window.frames["frame1"].print();
document.body.removeChild(frame1);
}, 500);
return false;
}
Call this like
<a href="#" onclick="javascript:printDiv('divwithcontenttoprint')"> Print </a>
The methods are covered pretty well now in npm's install documentation as well as the numerous other answers here.
npm install git+ssh://[email protected]:<githubname>/<githubrepo.git[#<commit-ish>]
npm install git+ssh://[email protected]:<githubname>/<githubrepo.git>[#semver:^x.x]
npm install git+https://[email protected]/<githubname>/<githubrepo.git>
npm install git://github.com/<githubname>/<githubrepo.git>
npm install github:<githubname>/<githubrepo>[#<commit-ish>]
However, something notable that has changed recently is npm adding the prepare
script to replace the prepublish
script. This fixes a longstanding problem where modules installed via git did not run the prepublish
script and thus did not complete the build steps that occur when a module is published to the npm registry. See https://github.com/npm/npm/issues/3055.
Of course, the module authors will need to update their package.json to use the new prepare
directive for this to start working.
Answering my own question for documentation. I'm sure there are other ways to accomplish this, but this works and this code is tested.

You can simulate events using ReactTestUtils but that's designed for unit testing.
I'd recommend not using valueLink for this case and simply listening to change events fired by the plugin and updating the input's state in response. The two-way binding utils more as a demo than anything else; they're included in addons only to emphasize the fact that pure two-way binding isn't appropriate for most applications and that you usually need more application logic to describe the interactions in your app.
I have never seen it done that way in JavaScript. If you want a function with optional parameters that get assigned default values if the parameters are omitted, here's a way to do it:
function(a, b) {
if (typeof a == "undefined") {
a = 10;
}
if (typeof b == "undefined") {
a = 20;
}
alert("a: " + a + " b: " + b);
}
Based on quentinadam's answer
Swift 5.1
// size refers to the width/height of your tile images, by default is 256.0
// Seems to get better results using round()
// frame.width is the width of the MKMapView
let zoom = round(log2(360 * Double(frame.width) / size / region.span.longitudeDelta))
I've made my own utility function to check several strings at once, rather than having an if statement full of if(str != null && !str.isEmpty && str2 != null && !str2.isEmpty)
. This is the function:
public class StringUtils{
public static boolean areSet(String... strings)
{
for(String s : strings)
if(s == null || s.isEmpty)
return false;
return true;
}
}
so I can simply write:
if(!StringUtils.areSet(firstName,lastName,address)
{
//do something
}
Just use look-arounds to solve this:
(?<=^|,)garp(?=$|,)
The difference with look-arounds and just regular groups are that with regular groups the comma would be part of the match, and with look-arounds it wouldn't. In this case it doesn't make a difference though.
Another simple way is to add all elements from the array to a new ArrayList using a for-each loop.
ArrayList<Element> list = new ArrayList<>();
for(Element e : array)
list.add(e);
Try adding "allowSyntheticDefaultImports": true
to your tsconfig.json
.
This basically tells the TypeScript compiler that it's okay to use an ES6 import statement, i. e.
import * as moment from 'moment/moment';
on a CommonJS module like Moment.js which doesn't declare a default export. The flag only affects type checking, not the generated code.
It is necessary if you use SystemJS as your module loader. The flag will be automatically turned on if you tell your TS compiler that you use SystemJS:
"module": "system"
This will also remove any errors thrown by IDEs if they are configured to make use of the tsconfig.json
.
The way I do it is:
in the location I run the spark-submit
script do
$ cp /etc/spark/conf/log4j.properties .
$ nano log4j.properties
change INFO
to what ever level of logging you want and then run your spark-submit

To create your own delegate, first you need to create a protocol and declare the necessary methods, without implementing. And then implement this protocol into your header class where you want to implement the delegate or delegate methods.
A protocol must be declared as below:
@protocol ServiceResponceDelegate <NSObject>
- (void) serviceDidFailWithRequestType:(NSString*)error;
- (void) serviceDidFinishedSucessfully:(NSString*)success;
@end
This is the service class where some task should be done. It shows how to define delegate and how to set the delegate. In the implementation class after the task is completed the delegate's the methods are called.
@interface ServiceClass : NSObject
{
id <ServiceResponceDelegate> _delegate;
}
- (void) setDelegate:(id)delegate;
- (void) someTask;
@end
@implementation ServiceClass
- (void) setDelegate:(id)delegate
{
_delegate = delegate;
}
- (void) someTask
{
/*
perform task
*/
if (!success)
{
[_delegate serviceDidFailWithRequestType:@”task failed”];
}
else
{
[_delegate serviceDidFinishedSucessfully:@”task success”];
}
}
@end
This is the main view class from where the service class is called by setting the delegate to itself. And also the protocol is implemented in the header class.
@interface viewController: UIViewController <ServiceResponceDelegate>
{
ServiceClass* _service;
}
- (void) go;
@end
@implementation viewController
//
//some methods
//
- (void) go
{
_service = [[ServiceClass alloc] init];
[_service setDelegate:self];
[_service someTask];
}
That's it, and by implementing delegate methods in this class, control will come back once the operation/task is done.
First, to describe dynamic cast in C terms, we have to represent classes in C. Classes with virtual functions use a "VTABLE" of pointers to the virtual functions. Comments are C++. Feel free to reformat and fix compile errors...
// class A { public: int data; virtual int GetData(){return data;} };
typedef struct A { void**vtable; int data;} A;
int AGetData(A*this){ return this->data; }
void * Avtable[] = { (void*)AGetData };
A * newA() { A*res = malloc(sizeof(A)); res->vtable = Avtable; return res; }
// class B : public class A { public: int moredata; virtual int GetData(){return data+1;} }
typedef struct B { void**vtable; int data; int moredata; } B;
int BGetData(B*this){ return this->data + 1; }
void * Bvtable[] = { (void*)BGetData };
B * newB() { B*res = malloc(sizeof(B)); res->vtable = Bvtable; return res; }
// int temp = ptr->GetData();
int temp = ((int(*)())ptr->vtable[0])();
Then a dynamic cast is something like:
// A * ptr = new B();
A * ptr = (A*) newB();
// B * aB = dynamic_cast<B>(ptr);
B * aB = ( ptr->vtable == Bvtable ? (B*) aB : (B*) 0 );
If you need something like:
¦ A ¦ B
--+--------------------------------+---
1 ¦ #My comment, something else ¦
2 ¦ 1 ¦ 2
Your CSV may contain the following lines:
"#My comment, something else"
1,2
Pay close attention at the 'quotes' in the first line.
When converting your text to columns using the Excel wizard, remember checking the 'Treat consecutive delimiters as one', setting it to use 'quotes' as delimiter.
Thus, Excel will split the text at the commas, keeping the 'comment' line as a single column value (and it will remove the quotes).
Good explanations for why you can't do what you're trying to do already provided. As a solution, maybe consider:
public class foo
{
static class priceInfo
{
public double lastPrice = 0;
public double price = 0;
public Price priceObject = new Price ();
}
public static void main ( String args[] )
{
int period = 2000;
int delay = 2000;
final priceInfo pi = new priceInfo ();
Timer timer = new Timer ();
timer.scheduleAtFixedRate ( new TimerTask ()
{
public void run ()
{
pi.price = pi.priceObject.getNextPrice ( pi.lastPrice );
System.out.println ();
pi.lastPrice = pi.price;
}
}, delay, period );
}
}
Seems like probably you could do a better design than that, but the idea is that you could group the updated variables inside a class reference that doesn't change.

Violating the Java naming conventions (variable names and method names start with lowercase, class names start with uppercase) is contributing to your confusion.
The variable Random
is only "in scope" inside the main
method. It's not accessible to any methods called by main
. When you return from main
, the variable disappears (it's part of the stack frame).
If you want all of the methods of your class to use the same Random
instance, declare a member variable:
class MyObj {
private final Random random = new Random();
public void compTurn() {
while (true) {
int a = random.nextInt(10);
if (possibles[a] == 1)
break;
}
}
}
To get the count of certain type extensions using LINQ you could use this simple code:
Dim exts() As String = {".docx", ".ppt", ".pdf"}
Dim query = (From f As FileInfo In directory.GetFiles()).Where(Function(f) exts.Contains(f.Extension.ToLower()))
Response.Write(query.Count())
In Oracle, you could do this:
create table D (
ID numeric(1),
CODE varchar(2),
constraint PK_D primary key (ID, CODE)
);
If it's a huuge array and it would take too much memory to serialize it to a string before writing, you can use streams:
var fs = require('fs');
var file = fs.createWriteStream('array.txt');
file.on('error', function(err) { /* error handling */ });
arr.forEach(function(v) { file.write(v.join(', ') + '\n'); });
file.end();
You can use simple Kotlin extension function like this:
fun TextView.setHtmlText(source: String) {
this.text = HtmlCompat.fromHtml(source, HtmlCompat.FROM_HTML_MODE_LEGACY)
}
And usage:
textViewMessage.setHtmlText("Message: <b>Hello World</b>")
Activity.getResources().getConfiguration().orientation
In the current version of Sublime Text 2 (Build: 2139), you can set the syntax for all files of a certain file extension using an option in the menu bar. Open a file with the extension you want to set a default for and navigate through the following menus: View -> Syntax -> Open all with current extension as... ->[your syntax choice]
.
Updated 2012-06-28: Recent builds of Sublime Text 2 (at least since Build 2181) have allowed the syntax to be set by clicking the current syntax type in the lower right corner of the window. This will open the syntax selection menu with the option to Open all with current extension as...
at the top of the menu.
Updated 2016-04-19: As of now, this also works for Sublime Text 3.
The other solutions work but they all make assumptions of for example the number of possible ranks and suits, or what the first and last rank may be. True, the layout of a deck of cards probably isn't going to change much in the foreseeable future. In general, however, it's neater to write code which makes as little assumptions as possible. My solution:
I've added a raw type to the Suit
enum, so I can use Suit(rawValue:)
to access the Suit
cases:
enum Suit: Int {
case Spades = 1
case Hearts, Diamonds, Clubs
func simpleDescription() -> String {
switch self {
case .Spades:
return "spades"
case .Hearts:
return "hearts"
case .Diamonds:
return "diamonds"
case .Clubs:
return "clubs"
}
}
func color() -> String {
switch self {
case .Spades:
return "black"
case .Clubs:
return "black"
case .Diamonds:
return "red"
case .Hearts:
return "red"
}
}
}
enum Rank: Int {
case Ace = 1
case Two, Three, Four, Five, Six, Seven, Eight, Nine, Ten
case Jack, Queen, King
func simpleDescription() -> String {
switch self {
case .Ace:
return "ace"
case .Jack:
return "jack"
case .Queen:
return "queen"
case .King:
return "king"
default:
return String(self.rawValue)
}
}
}
Below the implementation of Card's createDeck()
method. init(rawValue:)
is a failable initializer and returns an optional. By unwrapping and checking its value in both while statements, there's no need to assume the number of Rank
or Suit
cases:
struct Card {
var rank: Rank
var suit: Suit
func simpleDescription() -> String {
return "The \(rank.simpleDescription()) of \(suit.simpleDescription())"
}
func createDeck() -> [Card] {
var n = 1
var deck = [Card]()
while let rank = Rank(rawValue: n) {
var m = 1
while let suit = Suit(rawValue: m) {
deck.append(Card(rank: rank, suit: suit))
m += 1
}
n += 1
}
return deck
}
}
Here is how to call the createDeck
method:
let card = Card(rank: Rank.Ace, suit: Suit.Clubs)
let deck = card.createDeck()
if you use next tool: https://github.com/nomad/shenzhen

ipa build --verbose --scheme "${schemeName}"
You could also Stub Consecutive Calls (#10 in 2.8.9 api). In this case, you would use multiple thenReturn calls or one thenReturn call with multiple parameters (varargs).
import static org.junit.Assert.assertEquals;
import static org.mockito.Mockito.mock;
import static org.mockito.Mockito.when;
import org.junit.Before;
import org.junit.Test;
public class TestClass {
private Foo mockFoo;
@Before
public void setup() {
setupFoo();
}
@Test
public void testFoo() {
TestObject testObj = new TestObject(mockFoo);
assertEquals(0, testObj.bar());
assertEquals(1, testObj.bar());
assertEquals(-1, testObj.bar());
assertEquals(-1, testObj.bar());
}
private void setupFoo() {
mockFoo = mock(Foo.class);
when(mockFoo.someMethod())
.thenReturn(0)
.thenReturn(1)
.thenReturn(-1); //any subsequent call will return -1
// Or a bit shorter with varargs:
when(mockFoo.someMethod())
.thenReturn(0, 1, -1); //any subsequent call will return -1
}
}
string[] lines = text.Split(
Environment.NewLine.ToCharArray(),
StringSplitOptions.RemoveEmptyStrings);
The RemoveEmptyStrings option will make sure you don't have empty entries due to \n following a \r
(Edit to reflect comments:) Note that it will also discard genuine empty lines in the text. This is usually what I want but it might not be your requirement.
You can also use @Captor annotated ArgumentCaptor. For example:
@Mock
List<String> mockedList;
@Captor
ArgumentCaptor<String> argCaptor;
@BeforeTest
public void init() {
//Initialize objects annotated with @Mock, @Captor and @Spy.
MockitoAnnotations.initMocks(this);
}
@Test
public void shouldCallAddMethodTwice() {
mockedList.add("one");
mockedList.add("two");
Mockito.verify(mockedList, times(2)).add(argCaptor.capture());
assertEquals("one", argCaptor.getAllValues().get(0));
assertEquals("two", argCaptor.getAllValues().get(1));
}
One liner explanation
The standard versioning system is major.minor.build (e.g. 2.4.1)
npm checks and fixes the version of a particular package based on these characters
~ : major version is fixed, minor version is fixed, matches any build number
e.g. : ~2.4.1 means it will check for 2.4.x where x is anything
^ : major version is fixed, matches any minor version, matches any build number
e.g. : ^2.4.1 means it will check for 2.x.x where x is anything

You can try the below function to get value from JSON string,
public static String GetJSONValue(String JSONString, String Field)
{
return JSONString.substring(JSONString.indexOf(Field), JSONString.indexOf("\n", JSONString.indexOf(Field))).replace(Field+"\": \"", "").replace("\"", "").replace(",","");
}
I think this is enough to get you on a nice path:
Sub a()
Dim btn As Button
Application.ScreenUpdating = False
ActiveSheet.Buttons.Delete
Dim t As Range
For i = 2 To 6 Step 2
Set t = ActiveSheet.Range(Cells(i, 3), Cells(i, 3))
Set btn = ActiveSheet.Buttons.Add(t.Left, t.Top, t.Width, t.Height)
With btn
.OnAction = "btnS"
.Caption = "Btn " & i
.Name = "Btn" & i
End With
Next i
Application.ScreenUpdating = True
End Sub
Sub btnS()
MsgBox Application.Caller
End Sub
It creates the buttons and binds them to butnS(). In the btnS() sub, you should show your dialog, etc.
Most applications I've worked with use decimal
to represent money. This is based on the assumption that the application will never be concerned with more than one currency.
This assumption may be based on another assumption, that the application will never be used in other countries with different currencies. I've seen cases where that proved to be false.
Now that assumption is being challenged in a new way: New currencies such as Bitcoin are becoming more common, and they aren't specific to any country. It's not unrealistic that an application used in just one country may still need to support multiple currencies.
Some people will say that creating or even using a type just for money is "gold plating," or adding extra complexity beyond the known requirements. I strongly disagree. The more ubiquitous a concept is within your domain, the more important it is to make a reasonable effort to use the correct abstraction up front. If you want to see complexity, try working in an application that used to use decimal
and now there's an additional Currency
property next to every decimal
property.
If you use the wrong abstraction up front, replacing it later will be a hundred times more work. That means potentially introducing defects into existing code, and the best part is that those defects will likely involve amounts of money, transactions with money, or just anything with money.
And it's not that difficult to use something other than decimal. Google "nuget money type" and you'll see that numerous developers have created such abstractions (including me.) It's easy. It's as easy as using DateTime
instead of storing a date in a string
.
To update this, in Swift it can be done easily with:
array.reverse()
you can use use JQuery for deep copying :
var arr =[['abc'],['xyz']];
var newArr = $.extend(true, [], arr);
newArr.shift().shift();
console.log(arr); //arr still has [['abc'],['xyz']]
@Jacob already showed you how to use the Gaussian filter in Matlab, so I won't repeat that.
I would choose filter size to be about 3*sigma in each direction (round to odd integer). Thus, the filter decays to nearly zero at the edges, and you won't get discontinuities in the filtered image.
The choice of sigma depends a lot on what you want to do. Gaussian smoothing is low-pass filtering, which means that it suppresses high-frequency detail (noise, but also edges), while preserving the low-frequency parts of the image (i.e. those that don't vary so much). In other words, the filter blurs everything that is smaller than the filter.
If you're looking to suppress noise in an image in order to enhance the detection of small features, for example, I suggest to choose a sigma that makes the Gaussian just slightly smaller than the feature.
Since version 0.18.1 the .loc
method accepts a callable for selection. Together with lambda functions you can create very flexible chainable filters:
import numpy as np
import pandas as pd
df = pd.DataFrame(np.random.randint(0,100,size=(100, 4)), columns=list('ABCD'))
df.loc[lambda df: df.A == 80] # equivalent to df[df.A == 80] but chainable
df.sort_values('A').loc[lambda df: df.A > 80].loc[lambda df: df.B > df.A]
If all you're doing is filtering, you can also omit the .loc
.
Actually Boost does have such adaptor: boost::adaptors::reverse
.
#include <list>
#include <iostream>
#include <boost/range/adaptor/reversed.hpp>
int main()
{
std::list<int> x { 2, 3, 5, 7, 11, 13, 17, 19 };
for (auto i : boost::adaptors::reverse(x))
std::cout << i << '\n';
for (auto i : x)
std::cout << i << '\n';
}
This is an old question. CSS has evolved. There now is the vh
(viewport height) unit, also new layout options like flexbox
or CSS grid
to achieve classical designs in cleaner ways.
Dynamic programming is a technique used to avoid computing multiple times the same subproblem in a recursive algorithm.
Let's take the simple example of the Fibonacci numbers: finding the n th Fibonacci number defined by
Fn = Fn-1 + Fn-2 and F0 = 0, F1 = 1
The obvious way to do this is recursive:
def fibonacci(n):
if n == 0:
return 0
if n == 1:
return 1
return fibonacci(n - 1) + fibonacci(n - 2)
The recursion does a lot of unnecessary calculations because a given Fibonacci number will be calculated multiple times. An easy way to improve this is to cache the results:
cache = {}
def fibonacci(n):
if n == 0:
return 0
if n == 1:
return 1
if n in cache:
return cache[n]
cache[n] = fibonacci(n - 1) + fibonacci(n - 2)
return cache[n]
A better way to do this is to get rid of the recursion all-together by evaluating the results in the right order:
cache = {}
def fibonacci(n):
cache[0] = 0
cache[1] = 1
for i in range(2, n + 1):
cache[i] = cache[i - 1] + cache[i - 2]
return cache[n]
We can even use constant space and store only the necessary partial results along the way:
def fibonacci(n):
fi_minus_2 = 0
fi_minus_1 = 1
for i in range(2, n + 1):
fi = fi_minus_1 + fi_minus_2
fi_minus_1, fi_minus_2 = fi, fi_minus_1
return fi
How apply dynamic programming?
Dynamic programming generally works for problems that have an inherent left to right order such as strings, trees or integer sequences. If the naive recursive algorithm does not compute the same subproblem multiple times, dynamic programming won't help.
I made a collection of problems to help understand the logic: https://github.com/tristanguigue/dynamic-programing
int64_t
is typedef
you can find that in <stdint.h>
in C
In javascript you have to use \. to match a dot.
Example
"blah.tests.zibri.org".match('test\\..*')
null
and
"blah.test.zibri.org".match('test\\..*')
["test.zibri.org", index: 5, input: "blah.test.zibri.org", groups: undefined]
I do post an answer here for the question here that was closed even though the asnwers here helped, but were not sufficient.
So, this is in order to get a json array to a String[]
using jsonsimple.
According to the (marvelous) decode examples and docs, JSONArrays are java List, so we can access List methods.
From there, is it possible to transform it to a String[]
with the following:
JSONObject assemblingTags = (JSONObject) obj.get("assembling-tags");
JSONArray aTagsList = (JSONArray) assemblingTags.get("list");
String[] tagsList = (String[]) aTagsList.stream().toArray(String[]::new);
Unless the endian header is GCC-only, it provides macros you can use.
#include "endian.h"
...
if (__BYTE_ORDER == __LITTLE_ENDIAN) { ... }
else if (__BYTE_ORDER == __BIG_ENDIAN) { ... }
else { throw std::runtime_error("Sorry, this version does not support PDP Endian!");
...
Use trim($source)
before $s[$source]

This can occur when you are showing the dialog for a context that no longer exists. A common case - if the 'show dialog' operation is after an asynchronous operation, and during that operation the original activity (that is to be the parent of your dialog) is destroyed. For a good description, see this blog post and comments:
http://dimitar.me/android-displaying-dialogs-from-background-threads/
From the stack trace above, it appears that the facebook library spins off the auth operation asynchronously, and you have a Handler - Callback mechanism (onComplete called on a listener) that could easily create this scenario.
When I've seen this reported in my app, its pretty rare and matches the experience in the blog post. Something went wrong for the activity/it was destroyed during the work of the the AsyncTask. I don't know how your modification could result in this every time, but perhaps you are referencing an Activity as the context for the dialog that is always destroyed by the time your code executes?
Also, while I'm not sure if this is the best way to tell if your activity is running, see this answer for one method of doing so:
enum A {a,b,c}
enum B extends A {d}
/*B is {a,b,c,d}*/
can be written as:
public enum All {
a (ClassGroup.A,ClassGroup.B),
b (ClassGroup.A,ClassGroup.B),
c (ClassGroup.A,ClassGroup.B),
d (ClassGroup.B)
...
How it can be useful: Let say we want something like: We have events and we are using enums. Those enums can be grouped by similar processing. If we have operation with many elements, then some events starts operation, some are just step and other end the operation. To gather such operation and avoid long switch case we can group them as in example and use:
if(myEvent.is(State_StatusGroup.START)) makeNewOperationObject()..
if(myEnum.is(State_StatusGroup.STEP)) makeSomeSeriousChanges()..
if(myEnum.is(State_StatusGroup.FINISH)) closeTransactionOrSomething()..
Example:
public enum AtmOperationStatus {
STARTED_BY_SERVER (State_StatusGroup.START),
SUCCESS (State_StatusGroup.FINISH),
FAIL_TOKEN_TIMEOUT (State_StatusGroup.FAIL,
State_StatusGroup.FINISH),
FAIL_NOT_COMPLETE (State_StatusGroup.FAIL,
State_StatusGroup.STEP),
FAIL_UNKNOWN (State_StatusGroup.FAIL,
State_StatusGroup.FINISH),
(...)
private AtmOperationStatus(StatusGroupInterface ... pList){
for (StatusGroupInterface group : pList){
group.addMember(this);
}
}
public boolean is(StatusGroupInterface with){
for (AtmOperationStatus eT : with.getMembers()){
if( eT .equals(this)) return true;
}
return false;
}
// Each group must implement this interface
private interface StatusGroupInterface{
EnumSet<AtmOperationStatus> getMembers();
void addMember(AtmOperationStatus pE);
}
// DEFINING GROUPS
public enum State_StatusGroup implements StatusGroupInterface{
START, STEP, FAIL, FINISH;
private List<AtmOperationStatus> members = new LinkedList<AtmOperationStatus>();
@Override
public EnumSet<AtmOperationStatus> getMembers() {
return EnumSet.copyOf(members);
}
@Override
public void addMember(AtmOperationStatus pE) {
members.add(pE);
}
static { // forcing initiation of dependent enum
try {
Class.forName(AtmOperationStatus.class.getName());
} catch (ClassNotFoundException ex) {
throw new RuntimeException("Class AtmEventType not found", ex);
}
}
}
}
//Some use of upper code:
if (p.getStatus().is(AtmOperationStatus.State_StatusGroup.FINISH)) {
//do something
}else if (p.getStatus().is(AtmOperationStatus.State_StatusGroup.START)) {
//do something
}
Add some more advanced:
public enum AtmEventType {
USER_DEPOSIT (Status_EventsGroup.WITH_STATUS,
Authorization_EventsGroup.USER_AUTHORIZED,
ChangedMoneyAccountState_EventsGroup.CHANGED,
OperationType_EventsGroup.DEPOSIT,
ApplyTo_EventsGroup.CHANNEL),
SERVICE_DEPOSIT (Status_EventsGroup.WITH_STATUS,
Authorization_EventsGroup.TERMINAL_AUTHORIZATION,
ChangedMoneyAccountState_EventsGroup.CHANGED,
OperationType_EventsGroup.DEPOSIT,
ApplyTo_EventsGroup.CHANNEL),
DEVICE_MALFUNCTION (Status_EventsGroup.WITHOUT_STATUS,
Authorization_EventsGroup.TERMINAL_AUTHORIZATION,
ChangedMoneyAccountState_EventsGroup.DID_NOT_CHANGED,
ApplyTo_EventsGroup.DEVICE),
CONFIGURATION_4_C_CHANGED(Status_EventsGroup.WITHOUT_STATUS,
ApplyTo_EventsGroup.TERMINAL,
ChangedMoneyAccountState_EventsGroup.DID_NOT_CHANGED),
(...)
At above if we have some fail (myEvent.is(State_StatusGroup.FAIL)) then iterating by previous events we can easily check if we must revert money transfer by:
if(myEvent2.is(ChangedMoneyAccountState_EventsGroup.CHANGED)) rollBack()..
It can be useful for:
- including explicite meta-data about processing logic, less to remember
- implementing some of multi-inheritance
- we don't want to use class structures, ex. for sending short status messages
All the answers here use JSON objects. This gave us problems with the
$this->input->post()
methods of our Codeigniter controllers. The CI_Controller
cannot read JSON directly.
We used this method to do it WITHOUT JSON
func postRequest() {
// Create url object
guard let url = URL(string: yourURL) else {return}
// Create the session object
let session = URLSession.shared
// Create the URLRequest object using the url object
var request = URLRequest(url: url)
// Set the request method. Important Do not set any other headers, like Content-Type
request.httpMethod = "POST" //set http method as POST
// Set parameters here. Replace with your own.
let postData = "param1_id=param1_value¶m2_id=param2_value".data(using: .utf8)
request.httpBody = postData
// Create a task using the session object, to run and return completion handler
let webTask = session.dataTask(with: request, completionHandler: {data, response, error in
guard error == nil else {
print(error?.localizedDescription ?? "Response Error")
return
}
guard let serverData = data else {
print("server data error")
return
}
do {
if let requestJson = try JSONSerialization.jsonObject(with: serverData, options: .mutableContainers) as? [String: Any]{
print("Response: \(requestJson)")
}
} catch let responseError {
print("Serialisation in error in creating response body: \(responseError.localizedDescription)")
let message = String(bytes: serverData, encoding: .ascii)
print(message as Any)
}
// Run the task
webTask.resume()
}
Now your CI_Controller will be able to get param1
and param2
using $this->input->post('param1')
and $this->input->post('param2')
Be carreful of the know bug with SwitchCompat
It's a bug with corrupt file in drawable-hdpi on AppCompat https://code.google.com/p/android/issues/detail?id=78262
To fix it, juste override it with this 2 files https://github.com/lopespm/quick-fix-switchcompat-resources Add it on your directory drawable-hdpi
XML
<android.support.v7.widget.SwitchCompat
android:id="@+id/dev_switch_show_dev_only"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
And nothing was necessary on Java
