Around 1:51 in the video, notice how she puts a <script>
tag in there? The way it works is like this:
Create an html file (that's just a text file with a .html
ending) somewhere on your computer. In the same folder that you put index.html
, put a javascript file (that's just a textfile with a .js
ending - let's call it game.js
). Then, in your index.html
file, put some html that includes the script tag with game.js
, like Mary did in the video. index.html
should look something like this:
<html>
<head>
<script src="game.js"></script>
</head>
</html>
Now, double click on that file in finder, and it should open it up in your browser. To open up the console to see the output of your javascript code, hit Command-alt-j (those three buttons at the same time).
Good luck on your journey, hope it's as fun for you as it has been for me so far :)
A slight variation on Cocoanuts answer (that helped me solve this) when the button was in the footer of a table (which prevents you from finding the 'clicked cell':
-(IBAction) buttonAction:(id)sender;
{
id parent1 = [sender superview]; // UiTableViewCellContentView
id parent2 = [parent1 superview]; // custom cell containing the content view
id parent3 = [parent2 superview]; // UITableView containing the cell
id parent4 = [parent3 superview]; // UIView containing the table
UIView *myContentView = (UIView *)parent1;
UITableViewCell *myTableCell = (UITableViewCell *)parent2;
UITableView *myTable = (UITableView *)parent3;
UIView *mainView = (UIView *)parent4;
CGRect footerViewRect = myTableCell.frame;
CGRect rect3 = [myTable convertRect:footerViewRect toView:mainView];
[cc doSomethingOnScreenAtY:rect3.origin.y];
}

I had a similar problem. I wanted to move files and folder structures and overwrite existing files, but not delete anything which is in the destination folder structure.
I solved it by using os.walk()
, recursively calling my function and using shutil.move()
on files which I wanted to overwrite and folders which did not exist.
It works like shutil.move()
, but with the benefit that existing files are only overwritten, but not deleted.
import os
import shutil
def moverecursively(source_folder, destination_folder):
basename = os.path.basename(source_folder)
dest_dir = os.path.join(destination_folder, basename)
if not os.path.exists(dest_dir):
shutil.move(source_folder, destination_folder)
else:
dst_path = os.path.join(destination_folder, basename)
for root, dirs, files in os.walk(source_folder):
for item in files:
src_path = os.path.join(root, item)
if os.path.exists(dst_file):
os.remove(dst_file)
shutil.move(src_path, dst_path)
for item in dirs:
src_path = os.path.join(root, item)
moverecursively(src_path, dst_path)
What you could do is cheat a little bit by setting width
and height
to 0 to hide the actual image and apply some CSS to do what you want:
#aks {
width:0px;
height:0px;
background:url('http://dummyimage.com/100x100/000/fff');
padding:50px;
}
#aks:hover {
background: url('http://dummyimage.com/100x100/eb00eb/fff');
}
And the padding making the img
tag the size you want it to have (half the size of your actual image).
var list = new List<string>();
var queryable = list.AsQueryable();
Add a reference to: System.Linq
if (iv_new_pwd.isSelected()) {
iv_new_pwd.setSelected(false);
Log.d("mytag", "in case 1");
edt_new_pwd.setInputType(InputType.TYPE_CLASS_TEXT);
} else {
Log.d("mytag", "in case 1");
iv_new_pwd.setSelected(true);
edt_new_pwd.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
}
Using Bash you may insert a TAB character programmatically like so:
TAB=$'\t'
echo 'line' | sed "s/.*/${TAB}&/g"
echo 'line' | sed 's/.*/'"${TAB}"'&/g' # use of Bash string concatenation
If you are still getting the error after you have done with all above steps, go to your projects bootstrap->cache->config.php
remove the provider & aliases entries from the cached array manually.
All algorithms can be defined recursively. That makes it much, much easier to visualize and prove.
Some algorithms (e.g., the Ackermann Function) cannot (easily) be specified iteratively.
A recursive implementation will use more memory than a loop if tail call optimization can't be performed. While iteration may use less memory than a recursive function that can't be optimized, it has some limitations in its expressive power.
The only way not to capture something is using look-around assertions:
(?<=123-)((apple|banana)(?=-456)|(?=456))
Because even with non-capturing groups (?:…)
the whole regular expression captures their matched contents. But this regular expression matches only apple
or banana
if it’s preceded by 123-
and followed by -456
, or it matches the empty string if it’s preceded by 123-
and followed by 456
.
|Lookaround | Name | What it Does |
-----------------------------------------------------------------------
|(?=foo) | Lookahead | Asserts that what immediately FOLLOWS the |
| | | current position in the string is foo |
-------------------------------------------------------------------------
|(?<=foo) | Lookbehind | Asserts that what immediately PRECEDES the|
| | | current position in the string is foo |
-------------------------------------------------------------------------
|(?!foo) | Negative | Asserts that what immediately FOLLOWS the |
| | Lookahead | current position in the string is NOT foo|
-------------------------------------------------------------------------
|(?<!foo) | Negative | Asserts that what immediately PRECEDES the|
| | Lookbehind | current position in the string is NOT foo|
-------------------------------------------------------------------------
Use https://search.maven.org/ manually with the prefix fc: to search for class names. Both Netbeans and Eclipse seem to be too stupid to use that search interface and the gigabytes of downloaded repository indexes seem to not contain any class information. Total waste of disk space. Those IDE projects are so badly maintained lately, I wish they would move development to GitHub.
If you still want a custom filter you can pass in the search model to the filter:
<article data-ng-repeat="result in results | cartypefilter:search" class="result">
Where definition for the cartypefilter can look like this:
app.filter('cartypefilter', function() {
return function(items, search) {
if (!search) {
return items;
}
var carType = search.carType;
if (!carType || '' === carType) {
return items;
}
return items.filter(function(element, index, array) {
return element.carType.name === search.carType;
});
};
});
The checking of the presence of the member before assigning it is, in my opinion, quite ugly.
Kohana has a useful function to make selecting parameters simple.
You can make your own like so...
function arrayGet($array, $key, $default = NULL)
{
return isset($array[$key]) ? $array[$key] : $default;
}
And then do something like...
$page = arrayGet($_GET, 'p', 1);
In advance of my questions being answered, this is how I'd go about it:
Minimize the number of statements and the work they do issued in relative terms.
All scenarios assume you have a table of IDs (PURGE_IDS
) to delete from TABLE_1
, TABLE_2
, etc.
Consider Using CREATE TABLE AS SELECT for really large deletes
If there's no concurrent activity, and you're deleting 30+ % of the rows in one or more of the tables, don't delete; perform a create table as select
with the rows you wish to keep, and swap the new table out for the old table. INSERT /*+ APPEND */ ... NOLOGGING
is surprisingly cheap if you can afford it. Even if you do have some concurrent activity, you may be able to use Online Table Redefinition to rebuild the table in-place.
Don't run DELETE statements you know won't delete any rows
If an ID value exists in at most one of the six tables, then keep track of which IDs you've deleted - and don't try to delete those IDs from any of the other tables.
CREATE TABLE TABLE1_PURGE NOLOGGING
AS
SELECT ID FROM PURGE_IDS INNER JOIN TABLE_1 ON PURGE_IDS.ID = TABLE_1.ID;
DELETE FROM TABLE1 WHERE ID IN (SELECT ID FROM TABLE1_PURGE);
DELETE FROM PURGE_IDS WHERE ID IN (SELECT ID FROM TABLE1_PURGE);
DROP TABLE TABLE1_PURGE;
and repeat.
Manage Concurrency if you have to
Another way is to use PL/SQL looping over the tables, issuing a rowcount-limited delete statement. This is most likely appropriate if there's significant insert/update/delete concurrent load against the tables you're running the deletes against.
declare
l_sql varchar2(4000);
begin
for i in (select table_name from all_tables
where table_name in ('TABLE_1', 'TABLE_2', ...)
order by table_name);
loop
l_sql := 'delete from ' || i.table_name ||
' where id in (select id from purge_ids) ' ||
' and rownum <= 1000000';
loop
commit;
execute immediate l_sql;
exit when sql%rowcount <> 1000000; -- if we delete less than 1,000,000
end loop; -- no more rows need to be deleted!
end loop;
commit;
end;
Using with Moment.js and Comparison Query Operators
var today = moment().startOf('day');
// "2018-12-05T00:00:00.00
var tomorrow = moment(today).endOf('day');
// ("2018-12-05T23:59:59.999
Example.find(
{
// find in today
created: { '$gte': today, '$lte': tomorrow }
// Or greater than 5 days
// created: { $lt: moment().add(-5, 'days') },
}), function (err, docs) { ... });
var id_tag = [1,2,3,78,5,6,7,8,47,34,90];
var delete_where_id_tag = 90
id_tag =id_tag.filter((x)=> x!=delete_where_id_tag);
You have two options as far as I know:
SaveChanges()
.If you use option 2, you're losing some of the abstraction that the Entity Framework gives you, but if you need to perform a very large update, this might be the best choice for performance reasons.

You are running your HTML from a different host than the host you are requesting. Because of this, you are getting blocked by the same origin policy.
One way around this is to use JSONP. This allows cross-site requests.
In JSON, you are returned:
{a: 5, b: 6}
In JSONP, the JSON is wrapped in a function call, so it becomes a script, and not an object.
callback({a: 5, b: 6})
You need to edit your REST service to accept a parameter called callback
, and then to use the value of that parameter as the function name. You should also change the content-type
to application/javascript
.
For example: http://localhost:8080/restws/json/product/get?callback=process
should output:
process({a: 5, b: 6})
In your JavaScript, you will need to tell jQuery to use JSONP. To do this, you need to append ?callback=?
to the URL.
$.getJSON("http://localhost:8080/restws/json/product/get?callback=?",
function(data) {
alert(data);
});
If you use $.ajax
, it will auto append the ?callback=?
if you tell it to use jsonp
.
$.ajax({
type: "GET",
dataType: "jsonp",
url: "http://localhost:8080/restws/json/product/get",
success: function(data){
alert(data);
}
});
An alternative to other layouts, might be to put your panel with the GridLayout, inside another panel that is a FlowLayout. That way your spacing will be intact but will not expand across the entire available space.
Working with Intellij, because I don't know how to set keyboard shortcut to mvn spring-boot:run -Dspring.profiles.active=dev
, I have to do this:
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<jvmArguments>
-Dspring.profiles.active=dev
</jvmArguments>

You're trying to import all of those modules at once. Even if one of them fails, the rest will not import. For example:
try:
import datetime
import foo
import sys
except ImportError:
pass
Let's say foo
doesn't exist. Then only datetime
will be imported.
What you can do is import the sys module at the beginning of the file, before the try/except statement:
import sys
try:
import numpy as np
import pyfits as pf
import scipy.ndimage as nd
import pylab as pl
import os
import heapq
from scipy.optimize import leastsq
except ImportError:
print "Error: missing one of the libraries (numpy, pyfits, scipy, matplotlib)"
sys.exit()
Ted, as you probably found out, you unfortunately can't do that on Android. Dialogs are modal, but asynchronous, and it will definitely disrupt the sequence you're trying to establish as you would have done on .NET (or Windows for that matter). You will have to twist your code around and break some logic that would have been very easy to follow based on your example.
Another very simple example is to save data in a file, only to find out that the file is already there and asking to overwrite it or not. Instead of displaying a dialog and having an if statement to act upon the result (Yes/No), you will have to use callbacks (called listeners in Java) and split your logic into several functions.
On Windows, when a dialog is shown, the message pump continues in the background (only the current message being processed is on hold), and that works just fine. That allows users to move your app and let is repaint while you're displaying a dialog box for example. WinMo supports synchronous modal dialogs, so does BlackBerry but just not Android.
puts
adds a new line to the end of each argument if there is not one already.
print
does not add a new line.
For example:
puts [[1,2,3], [4,5,nil]]
Would return:
1 2 3 4 5
Whereas print [[1,2,3], [4,5,nil]]
would return:
[[1,2,3], [4,5,nil]]
Notice how puts does not output the nil value whereas print does.
String.Format("{0:#,###.##}", value)
A more complex example from String Formatting in C#:
String.Format("{0:$#,##0.00;($#,##0.00);Zero}", value);
This will output “$1,240.00" if passed 1243.50. It will output the same format but in parentheses if the number is negative, and will output the string “Zero” if the number is zero.
As a workaround a generic "ObjectHolder" can be used. See code example below.
The sample output is:
name: John Doe
dob:1953-12-17
name: Jim Miller
dob:1947-04-18
so the Person parameter has been modified since it's wrapped in the Holder which is passed by value - the generic param inside is a reference where the contents can be modified - so actually a different person is returned and the original stays as is.
/**
* show work around for missing call by reference in java
*/
public class OutparamTest {
/**
* a test class to be used as parameter
*/
public static class Person {
public String name;
public String dob;
public void show() {
System.out.println("name: "+name+"\ndob:"+dob);
}
}
/**
* ObjectHolder (Generic ParameterWrapper)
*/
public static class ObjectHolder<T> {
public ObjectHolder(T param) {
this.param=param;
}
public T param;
}
/**
* ObjectHolder is substitute for missing "out" parameter
*/
public static void setPersonData(ObjectHolder<Person> personHolder,String name,String dob) {
// Holder needs to be dereferenced to get access to content
personHolder.param=new Person();
personHolder.param.name=name;
personHolder.param.dob=dob;
}
/**
* show how it works
*/
public static void main(String args[]) {
Person jim=new Person();
jim.name="Jim Miller";
jim.dob="1947-04-18";
ObjectHolder<Person> testPersonHolder=new ObjectHolder(jim);
// modify the testPersonHolder person content by actually creating and returning
// a new Person in the "out parameter"
setPersonData(testPersonHolder,"John Doe","1953-12-17");
testPersonHolder.param.show();
jim.show();
}
}

For those who don't want to use colored background to beat the selected state
Simply you can beat the problem by using #Selector & if statement to change the UIButton colors for each state individually easily
For Example:
override func viewDidLoad() {
super.viewDidLoad()
self.myButtonOutlet.backgroundColor = UIColor.white //to reset the button color to its original color ( optionally )
}
@IBOutlet weak var myButtonOutlet: UIButton!{
didSet{ // Button selector and image here
self.myButtonOutlet.setImage(UIImage(systemName: ""), for: UIControl.State.normal)
self.myButtonOutlet.setImage(UIImage(systemName: "checkmark"), for: UIControl.State.selected)
self.myButtonOutlet.addTarget(self, action: #selector(tappedButton), for: UIControl.Event.touchUpInside)
}
}
@objc func tappedButton() { // Colors selection is here
if self.myButtonOutlet.isSelected == true {
self.myButtonOutlet.isSelected = false
self.myButtonOutlet.backgroundColor = UIColor.white
} else {
self.myButtonOutlet.isSelected = true
self.myButtonOutlet.backgroundColor = UIColor.black
self.myButtonOutlet.tintColor00 = UIColor.white
}
}
I got this same error when I was trying to import an Eclipse NDK project into Android Studio. It turns out, for NDK support in Android Studio, you need to use a new gradle and android plugin (and gradle version 2.5+ for that matter). This plugin, requires changes in the module's build.gradle file. Specifically the "android{...}" object should be inside "model{...}" object like this:
apply plugin: 'com.android.model.application'
model {
android {
....
}
}
So if you have updated your gradle configuration to use the new gradle plugin, and the new android plugin, but didn't change the module's build.gradle syntax, you could get "Gradle DSL method not found: 'android()'" error.
I prepared a patch file here that has some further explanations in the comments: https://gist.github.com/shumoapp/91d815de6e01f5921d1f These are the changes I had to do after importing the native-audio ndk project into Android Studio.
It appeared quite convenient for me to have a remote tmux session using the tmux new -d <shell cmd>
syntax like this:
ssh someone@elsewhere 'tmux new -d sleep 600'
This will launch new session on elsewhere
host and ssh command on local machine will return to shell almost instantly. You can then ssh to the remote host and tmux attach
to that session. Note that there's nothing about local tmux running, only remote!
Also, if you want your session to persist after the job is done, simply add a shell launcher after your command, but don't forget to enclose in quotes:
ssh someone@elsewhere 'tmux new -d "~/myscript.sh; bash"'
Request and response.
To understand the req
, try out console.log(req);

I ran some other question regarding ARIA. But it's content looks more promising for this question. would like to share them
What is ARIA?
If you put effort into making your website accessible to users with a variety of different browsing habits and physical disabilities, you'll likely recognize the role and aria-* attributes. WAI-ARIA (Accessible Rich Internet Applications) is a method of providing ways to define your dynamic web content and applications so that people with disabilities can identify and successfully interact with it. This is done through roles that define the structure of the document or application, or through aria-* attributes defining a widget-role, relationship, state, or property.
ARIA use is recommended in the specifications to make HTML5 applications more accessible. When using semantic HTML5 elements, you should set their corresponding role.
And see this you tube video for ARIA live.
Instead of initializing the variables with arbitrary values (for example int smallest = 9999, largest = 0
) it is safer to initialize the variables with the largest and smallest values representable by that number type (that is int smallest = Integer.MAX_VALUE, largest = Integer.MIN_VALUE
).
Since your integer array cannot contain a value larger than Integer.MAX_VALUE
and smaller than Integer.MIN_VALUE
your code works across all edge cases.
Inside Eclipse I've used the Clay plugin (ex Clay-Azurri). The free version allows to introspect ("reverse engineer") an existing DB schema (via JDBC) and make a diagram of some selected tables.
This helped me:
<p>Date/Time: <span id="datetime"></span></p><script>var dt = new Date();
document.getElementById("datetime").innerHTML=dt.toLocaleString();</script>
To answer the original question: yes, you can access the index value of a row in apply()
. It is available under the key name
and requires that you specify axis=1
(because the lambda processes the columns of a row and not the rows of a column).
Working example (pandas 0.23.4):
>>> import pandas as pd
>>> df = pd.DataFrame([[1,2,3],[4,5,6]], columns=['a','b','c'])
>>> df.set_index('a', inplace=True)
>>> df
b c
a
1 2 3
4 5 6
>>> df['index_x10'] = df.apply(lambda row: 10*row.name, axis=1)
>>> df
b c index_x10
a
1 2 3 10
4 5 6 40
There is a python package for this Autopy
The bitmap module can to screen grabbing (bitmap.capture_screen) It is multiplateform (Windows, Linux, Osx).
You should add overflow property like following:
.itemconfiguration
{
height: 300px;
overflow-y:auto;
width:215px;
float:left;
position:relative;
margin-left:-5px;
}
You need to specify the -vb option to increase the video bitrate, otherwise you get the default which produces smaller videos but with more artifacts.
Try something like this:
ffmpeg -r 25 -i %4d.png -vb 20M myvideo.mpg
Write a new class that holds all the values that you need and use the new class's object as the value in your HashMap
HashMap<String, MyObject>
class MyObject {
public String value1;
public int value2;
public List<String> value3;
}
@balusC I did as you wrote . In my case , I've added cookie information to be able to reuse the session .
// get the cookie if need
String cookies = conn.getHeaderField("Set-Cookie");
// open the new connnection again
conn = (HttpURLConnection) new URL(newUrl).openConnection();
conn.setRequestProperty("Cookie", cookies);
As others have written, you can use JavaScript to capture the event, prevent the default action (so that the cursor does not shift focus) and insert a tab character.
But, disabling the default behavior makes it impossible to move the focus out of the text area without using a mouse. Blind users interact with web pages using the keyboard and nothing else -- they can't see the mouse pointer to do anything useful with it, so it's keyboard or nothing. The tab key is the primary way to navigate the document, and especially forms. Overriding the default behavior of the tab key will make it impossible for blind users to move the focus to the next form element.
So, if you're writing a web site for a broad audience, I'd recommend against doing this without a compelling reason, and provide some kind of alternative for blind users that doesn't trap them in the textarea.
Sure, using the switch
construct you can simulate goto
in JavaScript. Unfortunately, the language doesn't provide goto
, but this is a good enough of a replacement.
let counter = 10
function goto(newValue) {
counter = newValue
}
while (true) {
switch (counter) {
case 10: alert("RINSE")
case 20: alert("LATHER")
case 30: goto(10); break
}
}
Assuming everything descends from object
(you are on your own if it doesn't), Python computes a method resolution order (MRO) based on your class inheritance tree. The MRO satisfies 3 properties:
If no such ordering exists, Python errors. The inner workings of this is a C3 Linerization of the classes ancestry. Read all about it here: https://www.python.org/download/releases/2.3/mro/
Thus, in both of the examples below, it is:
When a method is called, the first occurrence of that method in the MRO is the one that is called. Any class that doesn't implement that method is skipped. Any call to super
within that method will call the next occurrence of that method in the MRO. Consequently, it matters both what order you place classes in inheritance, and where you put the calls to super
in the methods.

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services
find "Apache2.4" open the folder find the "ImagePath" in the right side, open "ImagePath" under "value Data" put the following path:
"C:\xampp\apache\bin\httpd.exe" -k runservice foe XAMPP for others point to the location where Apache is installed and inside locate the bin folder "C:(Apache installed location)\bin\httpd.exe" -k runservice
I would do
import os
path = os.path.normpath(path)
path.split(os.sep)
First normalize the path string into a proper string for the OS. Then os.sep
must be safe to use as a delimiter in string function split.
The info at http://nelenkov.blogspot.com/2012/05/storing-application-secrets-in-androids.html is a fairly pragmatic, but "uses-hidden-android-apis" based approach. It's something to consider when you really can't get around storing credentials/passwords locally on the device.
I've also created a cleaned up gist of that idea at https://gist.github.com/kbsriram/5503519 which might be helpful.
What if your program does not know upfront how much memory to allocate (hence you cannot use stack variables). Say linked lists, the lists can grow without knowing upfront what is its size. So allocating on a heap makes sense for a linked list when you are not aware of how many elements would be inserted into it.
A simple solution is to create a script start.sh that runs Java through nohup and then stores the PID to a file:
nohup java -jar myapplication.jar > log.txt 2> errors.txt < /dev/null &
PID=$!
echo $PID > pid.txt
Then your stop script stop.sh would read the PID from the file and kill the application:
PID=$(cat pid.txt)
kill $PID
Of course I've left out some details, like checking whether the process exists and removing pid.txt
if you're done.

hashMap.put(2, "Two");
hashMap.put(3, "Three");

You need to use the CONCAT()
function in MySQL for string concatenation:
UPDATE categories SET code = CONCAT(code, '_standard') WHERE id = 1;
Try this:
var request = (HttpWebRequest)WebRequest.Create("http://www.example.com/recepticle.aspx");
var postData = "thing1=hello";
postData += "&thing2=world";
var data = Encoding.ASCII.GetBytes(postData);
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = data.Length;
using (var stream = request.GetRequestStream())
{
stream.Write(data, 0, data.Length);
}
var response = (HttpWebResponse)request.GetResponse();
var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
You can add a wrapper around promise functionality to return an Observable to observer.
import { of, Observable, defer } from 'rxjs';
import { map } from 'rxjs/operators';
function getTodos$(): Observable<any> {
return defer(()=>{
return fetch('https://jsonplaceholder.typicode.com/todos/1')
.then(response => response.json())
.then(json => {
return json;
})
});
}
getTodos$().
subscribe(
(next)=>{
console.log('Data is:', next);
}
)
True
is equal to 1
.
>>> sum([True, True, False, False, False, True])

Use a TreeMap
. This is precisely what it's for.
If this map is passed to you and you cannot determine the type, then you can do the following:
SortedSet<String> keys = new TreeSet<>(map.keySet());
for (String key : keys) {
String value = map.get(key);
// do something
}
This will iterate across the map in natural order of the keys.
Technically, you can use anything that implements SortedMap
, but except for rare cases this amounts to TreeMap
, just as using a Map
implementation typically amounts to HashMap
.
For cases where your keys are a complex type that doesn't implement Comparable or you don't want to use the natural order then TreeMap
and TreeSet
have additional constructors that let you pass in a Comparator
:
// placed inline for the demonstration, but doesn't have to be a lambda expression
Comparator<Foo> comparator = (Foo o1, Foo o2) -> {
...
}
SortedSet<Foo> keys = new TreeSet<>(comparator);
keys.addAll(map.keySet());
Remember when using a TreeMap
or TreeSet
that it will have different performance characteristics than HashMap
or HashSet
. Roughly speaking operations that find or insert an element will go from O(1) to O(Log(N)).
In a HashMap
, moving from 1000 items to 10,000 doesn't really affect your time to lookup an element, but for a TreeMap
the lookup time will be about 3 times slower (assuming Log2). Moving from 1000 to 100,000 will be about 6 times slower for every element lookup.
I know there's an easier way that this, but darned if I can find it...
jcomeau@intrepid:~$ python -c 'import os; print(os.path.abspath("cat.wav"))'

If you want to make a certain set of JAR files (or .class files) available to every Java application on the machine, then your best bet is to add those files to /Library/Java/Extensions
.
Or, if you want to do it for every Java application, but only when your Mac OS X account runs them, then use ~/Library/Java/Extensions
instead.
EDIT: If you want to do this only for a particular application, as Thorbjørn asked, then you will need to tell us more about how the application is packaged.
It's perfectly possible to update multiple columns in the same statement, and in fact your code is doing it. So why does it seem that "INV_TOTAL is not updating, only the inv_discount"?
Because you're updating INV_TOTAL with INV_DISCOUNT, and the database is going to use the existing value of INV_DISCOUNT and not the one you change it to. So I'm afraid what you need to do is this:
UPDATE INVOICE
SET INV_DISCOUNT = DISC1 * INV_SUBTOTAL
, INV_TOTAL = INV_SUBTOTAL - (DISC1 * INV_SUBTOTAL)
WHERE INV_ID = I_INV_ID;
Perhaps that seems a bit clunky to you. It is, but the problem lies in your data model. Storing derivable values in the table, rather than deriving when needed, rarely leads to elegant SQL.
You did it the wrong way around. You are meant to reset first, to unstage the file, then checkout, to revert local changes.
Try this:
$ git reset foo/bar.txt
$ git checkout foo/bar.txt
You can acheive this using window.open()
method, passing _blank
as one of the parameter. You can refer the below links which has more information on this.

Hope this will help you.
I had the same problem and I solved it by reading the full line from the console with one scanner object, and then parsing the resulting string using a second scanner object.
Scanner console = new Scanner(System.in);
System.out.println("Enter input here:");
String inputLine = console.nextLine();
Scanner input = new Scanner(inputLine);
List<String> arg = new ArrayList<>();
while (input.hasNext()) {
arg.add(input.next().toLowerCase());
}
Generically, do
/while
is good for any sort of loop construct where one must execute the loop at least once. It is possible to emulate this sort of looping through either a straight while
or even a for
loop, but often the result is a little less elegant. I'll admit that specific applications of this pattern are fairly rare, but they do exist. One which springs to mind is a menu-based console application:
do {
char c = read_input();
process_input(c);
} while (c != 'Q');
The question is tagged WPF but the answers so far are specific WinForms and Win32.
To do this in WPF, simply construct a KeyEventArgs and call RaiseEvent on the target. For example, to send an Insert key KeyDown event to the currently focused element:
var key = Key.Insert; // Key to send
var target = Keyboard.FocusedElement; // Target element
var routedEvent = Keyboard.KeyDownEvent; // Event to send
target.RaiseEvent(
new KeyEventArgs(
Keyboard.PrimaryDevice,
PresentationSource.FromVisual(target),
0,
key)
{ RoutedEvent=routedEvent }
);
This solution doesn't rely on native calls or Windows internals and should be much more reliable than the others. It also allows you to simulate a keypress on a specific element.
Note that this code is only applicable to PreviewKeyDown, KeyDown, PreviewKeyUp, and KeyUp events. If you want to send TextInput events you'll do this instead:
var text = "Hello";
var target = Keyboard.FocusedElement;
var routedEvent = TextCompositionManager.TextInputEvent;
target.RaiseEvent(
new TextCompositionEventArgs(
InputManager.Current.PrimaryKeyboardDevice,
new TextComposition(InputManager.Current, target, text))
{ RoutedEvent = routedEvent }
);
Also note that:
Controls expect to receive Preview events, for example PreviewKeyDown should precede KeyDown
Using target.RaiseEvent(...) sends the event directly to the target without meta-processing such as accelerators, text composition and IME. This is normally what you want. On the other hand, if you really do what to simulate actual keyboard keys for some reason, you would use InputManager.ProcessInput() instead.

@gaurwraith, install poppler for Windows and use pdftoppm.exe as follows:
Download zip file with Poppler's latest binaries/dlls from http://blog.alivate.com.au/poppler-windows/ and unzip to a new folder in your program files folder. For example: "C:\Program Files (x86)\Poppler".
Add "C:\Program Files (x86)\Poppler\poppler-0.68.0\bin" to your SYSTEM PATH environment variable.
From cmd line install pdf2image module -> "pip install pdf2image".
@vishvAs vAsuki, this code should generate the jpgs you want through the subprocess module for all pages of one or more pdfs in a given folder:
import os, subprocess
pdf_dir = r"C:\yourPDFfolder"
os.chdir(pdf_dir)
pdftoppm_path = r"C:\Program Files (x86)\Poppler\poppler-0.68.0\bin\pdftoppm.exe"
for pdf_file in os.listdir(pdf_dir):
if pdf_file.endswith(".pdf"):
subprocess.Popen('"%s" -jpeg %s out' % (pdftoppm_path, pdf_file))
Or using the pdf2image module:
import os
from pdf2image import convert_from_path
pdf_dir = r"C:\yourPDFfolder"
os.chdir(pdf_dir)
for pdf_file in os.listdir(pdf_dir):
if pdf_file.endswith(".pdf"):
pages = convert_from_path(pdf_file, 300)
pdf_file = pdf_file[:-4]
for page in pages:
page.save("%s-page%d.jpg" % (pdf_file,pages.index(page)), "JPEG")

You can plot the means without resorting to external calculations and additional tables using stat_summary(...)
. In fact, stat_summary(...)
was designed for exactly what you are doing.
library(ggplot2)
library(reshape2) # for melt(...)
gg <- melt(df,id="gender") # df is your original table
ggplot(gg, aes(x=variable, y=value, fill=factor(gender))) +
stat_summary(fun.y=mean, geom="bar",position=position_dodge(1)) +
scale_color_discrete("Gender")
stat_summary(fun.ymin=min,fun.ymax=max,geom="errorbar",
color="grey80",position=position_dodge(1), width=.2)
To add "error bars" you cna also use stat_summary(...)
(here, I'm using the min and max value rather than sd because you have so little data).
ggplot(gg, aes(x=variable, y=value, fill=factor(gender))) +
stat_summary(fun.y=mean, geom="bar",position=position_dodge(1)) +
stat_summary(fun.ymin=min,fun.ymax=max,geom="errorbar",
color="grey40",position=position_dodge(1), width=.2) +

def numeric(equation):
if '+' in equation:
y = equation.split('+')
x = int(y[0])+int(y[1])
elif '-' in equation:
y = equation.split('-')
x = int(y[0])-int(y[1])
return x
When you log in to your developer account, you can find a link at the bottom of the download section for Xcode that says "Looking for an older version of Xcode?". In there you can find download links to older versions of Xcode and other developer tools
So I realize this is kind of old, but after much Googling, I couldn't find an answer I was happy with, so I came up with my own solution for breaking a FOR loop that immediately stops iteration, and thought I'd share it.
It requires the loop to be in a separate file, and exploits a bug in CMD error handling to immediately crash the batch processing of the loop file when redirecting the STDOUT of DIR to STDIN.

ECHO Simple test demonstrating loop breaking.

ECHO After LOOP
PAUSE
LOOP.cmd
FOR /L %%A IN (1,1,10) DO (
ECHO %%A
IF %%A EQU 3 DIR >&0 2>NUL )
)
When run, this produces the following output. You'll notice that both iteration and execution of the loop stops when %A = 3.

Press any key to continue . . .
If you need to preserve a single variable from the loop, have the loop ECHO the result of the variable, and use a FOR /F loop in the MainFile.cmd to parse the output of the LOOP.cmd file.
Example (using the same LOOP.cmd file as above):
MainFile.cmd
@ECHO OFF
ECHO.
ECHO Simple test demonstrating loop breaking.
ECHO.
FOR /F "delims=" %%L IN ('CMD /C %~dp0\LOOP.cmd') DO SET VARIABLE=%%L
ECHO After LOOP
ECHO.
ECHO %VARIABLE%
ECHO.
PAUSE
Output:
:>MainFile.cmd
Simple test demonstrating loop breaking.
After LOOP

Press any key to continue . . .
If you need to preserve multiple variables, you'll need to redirect them to temporary files as shown below.
MainFile.cmd
@ECHO OFF
ECHO.
ECHO Simple test demonstrating loop breaking.
ECHO.
CMD /C %~dp0\LOOP.cmd
ECHO After LOOP
ECHO.
SET /P VARIABLE1=<%TEMP%\1

ECHO %VARIABLE2%
ECHO.
PAUSE

@ECHO OFF
FOR /L %%A IN (1,1,10) DO (
IF %%A EQU 1 ECHO ONE >%TEMP%\1
IF %%A EQU 2 ECHO TWO >%TEMP%\2
IF %%A EQU 3 DIR >&0 2>NUL
)
Output:
:>MainFile.cmd

Press any key to continue . . .
I hope others find this useful for breaking loops that would otherwise take too long to exit due to continued iteration.
I wrote a function wrapper called bar()
for barplot()
to do what you are trying to do here, since I need to do similar things frequently. The Github link to the function is here. After copying and pasting it into R, you do
bar(dv = Species,
factors = c(Category, Reason),
dataframe = Reasonstats,
errbar = FALSE,
ylim=c(0, 140)) #I increased the upper y-limit to accommodate the legend.
The one convenience is that it will put a legend on the plot using the names of the levels in your categorical variable (e.g., "Decline" and "Improved"). If each of your levels has multiple observations, it can also plot the error bars (which does not apply here, hence errbar=FALSE
logrotate -d [your_config_file]
invokes debug mode, giving you a verbose description of what would happen, but leaving the log files untouched.
If you are using following devices:
Samsung S3 GT-I9305 (Android 4.1.2)
Mac OS 10.6.8
Do following:
# echo "0x04e8" >> ~/.android/adb_usb.ini
# adb kill-server
# adb devices
(if you are not using Samsung device, change the Vendor ID "0x04e8" to the correct value of your Vendor)
If still not working, you may want to try following:
(1) On your Samsung device, disable "USB Debugging" and re-enable it again
(and try the adb commands again)
(2) Disconnect the USB cable, and re-connect it again
(3) Uninstall Samsung Kies
(4) Install Android File Transfer
(5) Reboot your Mac and the Samsung device
(6) Use hardware device to test your Android app
After getting the devices connected but you suddenly unplug the USB cable, and suppose now "adb devices" cannot see your device any more, even after "adb kill-server", in this case, you may want to try the following:
(1) power off your Mac
(2) disable "USB debuggine" on your Samsung device
(3) power off your Samsung device
(4) power on your Mac
(5) power on your Samsung device
(6) enable "USB debuggine" on your Samsung device
(7) connect the USB cable
(8) Run "adb devices"
(9) You should see the attached device now
As far as I understand it, the sort function in the collection class can only be used to sort collections implementing the comparable interface.
You are supplying it a array of integers. You should probably wrap this around one of the know Wrapper classes such as Integer. Integer implements comparable.
Its been a long time since I have worked on some serious Java, however reading some matter on the sort function will help.
Just ask it for the objectForKey:@"b"
. If it returns nil
, no object is set at that key.
if ([xyz objectForKey:@"b"]) {
NSLog(@"There's an object set for key @\"b\"!");
} else {
NSLog(@"No object set for key @\"b\"");
}
Edit: As to your edited second question, it's simply NSUInteger mCount = [xyz count];
. Both of these answers are documented well and easily found in the NSDictionary class reference ([1] [2]).
Another approach to addressing the issue of multiple keys with the same min value:
>>> dd = {320:1, 321:0, 322:3, 323:0}
>>>
>>> from itertools import groupby
>>> from operator import itemgetter
>>>
>>> print [v for k,v in groupby(sorted((v,k) for k,v in dd.iteritems()), key=itemgetter(0)).next()[1]]
[321, 323]
If you are simply testing a local dev version of WordPress as I was an hitting timeouts when WordPress tries to update itself you can always disable updates for your local version like so: https://www.wpbeginner.com/wp-tutorials/how-to-disable-automatic-updates-in-wordpress/
Don't do this for a production site!
First of all, Applets are designed to be run from within the context of a browser (or applet viewer), they're not really designed to be added into other containers.
Technically, you can add a applet to a frame like any other component, but personally, I wouldn't. The applet is expecting a lot more information to be available to it in order to allow it to work fully.
Instead, I would move all of the "application" content to a separate component, like a JPanel
for example and simply move this between the applet or frame as required...
ps- You can use f.setLocationRelativeTo(null)
to center the window on the screen ;)
Updated
You need to go back to basics. Unless you absolutely must have one, avoid applets until you understand the basics of Swing, case in point...
Within the constructor of GalzyTable2
you are doing...
JApplet app = new JApplet(); add(app); app.init(); app.start();
...Why are you adding another applet to an applet??
Case in point...
Within the main
method, you are trying to add the instance of JFrame
to itself...
f.getContentPane().add(f, button2);
Instead, create yourself a class that extends from something like JPanel
, add your UI logical to this, using compound components if required.
Then, add this panel to whatever top level container you need.

You also seem to have a lack of understanding about how to use layout managers.
Take the time to read through Creating a GUI with Swing and Laying components out in a container
instead of doing it like that, why not just make the flyout position:fixed, top:0; left:0;
once your window has scrolled pass a certain height:
jQuery
$(window).scroll(function(){
if ($(this).scrollTop() > 135) {
$('#task_flyout').addClass('fixed');
} else {
$('#task_flyout').removeClass('fixed');
}
});

A very simple solution is to search your file(s) for non-ascii characters using a regular expression. This will nicely highlight all the spots where they are found with a border.
Search for [^\x00-\x7F]
and check the box for Regex.
The result will look like this (in dark mode):
Just hit on this when trying to solve this type of thing my self.
I did a selector that deals with the element after being something other than a p.
.here .is.the #selector h4 + * {...}
Hope this helps anyone who finds it :)
You can't select a sheet in a non-active workbook.
You must first activate the workbook, then you can select the sheet.
workbooks("A").activate
workbooks("A").worksheets("B").select
When you use Activate it automatically activates the workbook.
Note you can select >1 sheet in a workbook:
activeworkbook.sheets(array("sheet1","sheet3")).select
but only one sheet can be Active, and if you activate a sheet which is not part of a multi-sheet selection then those other sheets will become un-selected.
There is a built-in library called pickle
. Using pickle
you can dump objects to a file and load them later.
import pickle
f = open('store.pckl', 'wb')
pickle.dump(obj, f)
f.close()
f = open('store.pckl', 'rb')
obj = pickle.load(f)
f.close()
I am not sure if this is what you are looking for
if var<>"" then
dosomething
or
if isempty(thisworkbook.sheets("sheet1").range("a1").value)= false then
the ISEMPTY function can be used as well
SQL Error: ORA-30926: unable to get a stable set of rows in the source tables
30926. 00000 - "unable to get a stable set of rows in the source tables"
*Cause: A stable set of rows could not be got because of large dml
activity or a non-deterministic where clause.
*Action: Remove any non-deterministic where clauses and reissue the dml.
This Error occurred for me because of duplicate records(16K)
I tried with unique it worked .
but again when I tried merge without unique same proble occurred Second time it was due to commit
after merge if commit is not done same Error will be shown.
Without unique, Query will work if commit is given after each merge operation.
A later answer, but because no one gave this solution...
If you do not want to set the header on the HttpClient
instance by adding it to the DefaultRequestHeaders
, you could set headers per request.
But you will be obliged to use the SendAsync()
method.
This is the right solution if you want to reuse the HttpClient
-- which is a good practice for
Use it like this:
using (var requestMessage =
new HttpRequestMessage(HttpMethod.Get, "https://your.site.com"))
{
requestMessage.Headers.Authorization =
new AuthenticationHeaderValue("Bearer", your_token);
httpClient.SendAsync(requestMessage);
}
If the checkbox is created only with React.createElement
then the property
defaultChecked
is used.
React.createElement('input',{type: 'checkbox', defaultChecked: false});

Another method could be to split the string by ":" and then pop off the end.
var newString = string.split(":").pop();
Another way is to make your user a password-less sudo user
.
Type the following on command line:
sudo visudo
Then add the following and replace the <username>
with yours:
<username> ALL=(ALL) NOPASSWD: ALL
This will allow the user to execute sudo
command without having to ask for password (including application launched by the said user. This might be a security risk though
Another alternative of the curl-less method above is to use the native stream functions:
stream_context_create()
:
Creates and returns a stream context with any options supplied in options preset.
stream_get_contents()
:
Identical to
file_get_contents()
, except thatstream_get_contents()
operates on an already open stream resource and returns the remaining contents in a string, up to maxlength bytes and starting at the specified offset.
A POST function with these can simply be like this:
<?php
function post_request($url, array $params) {
$query_content = http_build_query($params);
$fp = fopen($url, 'r', FALSE, // do not use_include_path
stream_context_create([
'http' => [
'header' => [ // header array does not need '\r\n'
'Content-type: application/x-www-form-urlencoded',
'Content-Length: ' . strlen($query_content)
],
'method' => 'POST',
'content' => $query_content
]
]));
if ($fp === FALSE) {
return json_encode(['error' => 'Failed to get contents...']);
}
$result = stream_get_contents($fp); // no maxlength/offset
fclose($fp);
return $result;
}
If you want specifically do something when click on close button exactly like you described:
<a href="#" class="btn close_link" data-dismiss="modal">Close</a>
you need to attach an event using css selector:
$(document).on('click', '[data-dismiss="modal"]', function(){what you want to do})
But if you want to do something when modal close, you can use the already wrote tips
Node has a concept of Local modules & Global modules
Local modules are located within current project directory.
Global Modules are generally located at user's home directory, though we can change the path where global modules resides.
npm list
npm list --global
OR npm list --g
// It will list all the top level modules with its dependenciesnpm list -g --depth=0
Try the Offstage
widget
if attribute offstage:true
the not occupy the physical space and invisible,
if attribute offstage:false
it will occupy the physical space and visible
Offstage(
offstage: true,
child: Text("Visible"),
),
Because another class could extend it, and the child class needs to invoke a superclass constructor.
To add to @adilapapaya's answer. For ember-cli
users specifically, install tether
with
bower install --save tether
and then include it in your ember-cli-build.js
file before bootstrap, like so:
// tether (bootstrap 4 requirement)
app.import('bower_components/tether/dist/js/tether.min.js');
// bootstrap
app.import('bower_components/bootstrap/scss/bootstrap-flex.scss');
app.import('bower_components/bootstrap/dist/js/bootstrap.js');
Below are two methods that are superior to looping. Both handle a "no-find" case.
VLOOKUP
with error-handling if the variable doesn't exist (INDEX/MATCH
may be a better route than VLOOKUP
, ie if your two columns A and B were in reverse order, or were far apart)VBAs FIND
method (matching a whole string in column A given I use the xlWhole
argument)
Sub Method1()
Dim strSearch As String
Dim strOut As String
Dim bFailed As Boolean
strSearch = "trees"
On Error Resume Next
strOut = Application.WorksheetFunction.VLookup(strSearch, Range("A:B"), 2, False)
If Err.Number <> 0 Then bFailed = True
On Error GoTo 0
If Not bFailed Then
MsgBox "corresponding value is " & vbNewLine & strOut
Else
MsgBox strSearch & " not found"
End If
End Sub
Sub Method2()
Dim rng1 As Range
Dim strSearch As String
strSearch = "trees"
Set rng1 = Range("A:A").Find(strSearch, , xlValues, xlWhole)
If Not rng1 Is Nothing Then
MsgBox "Find has matched " & strSearch & vbNewLine & "corresponding cell is " & rng1.Offset(0, 1)
Else
MsgBox strSearch & " not found"
End If
End Sub
If you need to be able to compile code in environments that support the C++11 standard, but also need to be able to compile that same code in environments that don't support it, you could use a function macro to choose between std::round() and a custom function for each system. Just pass -DCPP11
or /DCPP11
to the C++11-compliant compiler (or use its built-in version macros), and make a header like this:
// File: rounding.h
#include <cmath>
#ifdef CPP11
#define ROUND(x) std::round(x)
#else /* CPP11 */
inline double myRound(double x) {
return (x >= 0.0 ? std::floor(x + 0.5) : std::ceil(x - 0.5));
}
#define ROUND(x) myRound(x)
#endif /* CPP11 */
For a quick example, see http://ideone.com/zal709 .
This approximates std::round() in environments that aren't C++11-compliant, including preservation of the sign bit for -0.0. It may cause a slight performance hit, however, and will likely have issues with rounding certain known "problem" floating-point values such as 0.49999999999999994 or similar values.
Alternatively, if you have access to a C++11-compliant compiler, you could just grab std::round() from its <cmath>
header, and use it to make your own header that defines the function if it's not already defined. Note that this may not be an optimal solution, however, especially if you need to compile for multiple platforms.
In my case, since I could not append a cache busting timestamp to the css url it turned out that I had to manually refresh the application pool in IIS 7.5.7600.
Every other avenue was pursued, right down to disabling the caching entirely for the site and also for the local browser (like ENTIRELY disabled for both), still didn't do the trick. Also "restarting" the website did nothing.
Same position as me? [Site Name] > "Application Pool" > "Recycle" is your last resort...
There is a way to get a range of values in a single query, but its a bit slow. It can be sped up by using cache tables.
assume you want a select with a range of all BOOLEAN values:
SELECT 0 as b UNION SELECT 1 as b;
we can make a view
CREATE VIEW ViewBoolean AS SELECT 0 as b UNION SELECT 1 as b;
then you can do a Byte by
CREATE VIEW ViewByteValues AS
SELECT b0.b + b1.b*2 + b2.b*4 + b3.b*8 + b4.b*16 + b5.b*32 + b6.b*64 + b7.b*128 as v FROM
ViewBoolean b0,ViewBoolean b1,ViewBoolean b2,ViewBoolean b3,ViewBoolean b4,ViewBoolean b5,ViewBoolean b6,ViewBoolean b7;
then you can do a
CREATE VIEW ViewInt16 AS
SELECT b0.v + b1.v*256 as v FROM
ViewByteValues b0,ViewByteValues b1;
then you can do a
SELECT v+MIN as x FROM ViewInt16 WHERE v<MAX-MIN;
To speed this up I skipped the auto-calculation of byte values and made myself a
CREATE VIEW ViewByteValues AS
SELECT 0 as v UNION SELECT 1 as v UNION SELECT ...
...
...254 as v UNION SELECT 255 as v;
If you need a range of dates you can do.
SELECT DATE_ADD('start_date',v) as day FROM ViewInt16 WHERE v<NumDays;
or
SELECT DATE_ADD('start_date',v) as day FROM ViewInt16 WHERE day<'end_date';
you might be able to speed this up with the slightly faster MAKEDATE function
SELECT MAKEDATE(start_year,1+v) as day FRON ViewInt16 WHERE day>'start_date' AND day<'end_date';
Please note that this tricks are VERY SLOW and only allow the creation of FINITE sequences in a pre-defined domain (for example int16 = 0...65536 )
I am sure you can modify the queries a bit to speed things up by hinting to MySQL where to stop calculating ;) (using ON clauses instead of WHERE clauses and stuff like that)
For example:
SELECT MIN + (b0.v + b1.v*256 + b2.v*65536 + b3.v*16777216) FROM
ViewByteValues b0,
ViewByteValues b1,
ViewByteValues b2,
ViewByteValues b3
WHERE (b0.v + b1.v*256 + b2.v*65536 + b3.v*16777216) < MAX-MIN;
will keep your SQL server busy for a few hours
However
SELECT MIN + (b0.v + b1.v*256 + b2.v*65536 + b3.v*16777216) FROM
ViewByteValues b0
INNER JOIN ViewByteValues b1 ON (b1.v*256<(MAX-MIN))
INNER JOIN ViewByteValues b2 ON (b2.v*65536<(MAX-MIN))
INNER JOIN ViewByteValues b3 ON (b3.v*16777216<(MAX-MIN)
WHERE (b0.v + b1.v*256 + b2.v*65536 + b3.v*16777216) < (MAX-MIN);
will run reasonably fast - even if MAX-MIN is huge as long as you limit the result with LIMIT 1,30 or something. a COUNT(*) however will take ages and if you make the mistake of adding ORDER BY when MAX-MIN is bigger than say 100k it will again take several seconds to calculate...
It’s easy; just do the following:
rvm implode
or
rm -rf ~/.rvm
And don’t forget to remove the script calls in the following files:
~/.bashrc
~/.bash_profile
~/.profile
And maybe others depending on whatever shell you’re using.
I had to change the import statement:
import org.junit.jupiter.api.Test;
to
import org.junit.Test;
After some trial and error, I found that
$computername = $env:computername
works to get a computer name, but sending $computername
to a file via Add-Content doesn't work.
I also tried $computername.Value
.
Instead, if I use
$computername = get-content env:computername
I can send it to a text file using
$computername | Out-File $file
both would work the same, its just two different methods to call the same function. Try the following:
<a href="javascript:history.back();">[Go Back]</a>
I had the same problem and i fixed by adding the component (MyComponentToUse) in exports array in the module where my component was declared (ModuleLower). Then i import ModuleLower in ModuleHigher, so i can reuse now my component ( MyComponentToUse) in the ModuleLower and the ModuleHigher

declarations: [
MyComponentToUse
],
exports: [
MyComponentToUse
]
})
export class ModuleLower {}
@NgModule({
imports: [
ModuleLower
]
})
export class ModuleHigher {}

After wasting a lot of time in finding its solution, I've found one. For your convenience I've used the complete code that you can replace your whole file with.
This is a general answer. Let's say you want to import a file named testjs.js into your angular 2 component. Create testjs.js in your assets folder:
assets > testjs.js
function test(){
alert('TestingFunction')
}
include testjs.js in your index.html
index.html
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Project1</title>
<base href="/">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="icon" type="image/x-icon" href="favicon.ico">
<script src="./assets/testjs.js"></script>
</head>
<body>
<app-root>Loading...</app-root>
</body>
</html>
In your app.component.ts or in any component.ts file where you want to call this js declare a variable and call the function like below:
app.component.ts
import { Component } from '@angular/core';
declare var test: any;
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
title = 'app works!';
f(){
new test();
}
}
Finally in your app.component.html test the function
app.component.html
<h1>
<button (click)='f()'>Test</button>
</h1>
If you are on a Mac, the Chrome dev team recommend the 'Network Link Conditioner Tool'
Either:

Or if you don't want to install Xcode:
Go to the Apple Download Center and search for Hardware IO Tools
I'f you're suppsed to be able to use it, then 3rd-party library should have a *.lib file as well as a *.dll file. You simply need to add the *.lib to the list of input file in your project's 'Linker' options.
This *.lib file isn't necessarily a 'static' library (which contains code): instead a *.lib can be just a file that links your executable to the DLL.
I maybe very late but you can use "nexe" module that compile nodejs + your script in one executable: https://github.com/crcn/nexe
You are indeed passing the first data item to the each function.
Pass data.programs to the each function instead. Change the code to as below:
<script>
$(document).ready(function() {
var data = { "programs": [ { "name":"zonealarm", "price":"500" }, { "name":"kaspersky", "price":"200" } ] };
$.each(data.programs, function(key,val) {
alert(key+val);
});
});
</script>
if you want php you can count the array and just make an if statement like
if((int)count($_FILES['i_dont_know_whats_coming_next'] > 2)
echo "error message";

//save with the modified palette
// note that wherever we have previously used RED or LIME, the
// new colors magically appear
out = new FileOutputStream("modified_palette.xls");
wb.write(out);
out.close();
XSSF:
XSSFWorkbook wb = new XSSFWorkbook();
XSSFSheet sheet = wb.createSheet();
XSSFRow row = sheet.createRow(0);
XSSFCell cell = row.createCell( 0);
cell.setCellValue("custom XSSF colors");
XSSFCellStyle style1 = wb.createCellStyle();
style1.setFillForegroundColor(new XSSFColor(new java.awt.Color(128, 0, 128)));
style1.setFillPattern(CellStyle.SOLID_FOREGROUND);
jQuery 1.4 has a new feature for doing this, and it rules. I've forgotten what it's called, but you use it like this:
$("a.directions-link").attr("href", function(i, href) {
return href + '?q=testing';
});
That loops over all the elements too, so no need for $.each
For Swift 3.x / Swift 4.0 / Swift 5.0 users with Alamofire >= 5.0
Used request modifier to increase and decrease the timeout interval.
Alamofire's request creation methods offer the most common parameters for customization but sometimes those just aren't enough. The URLRequests created from the passed values can be modified by using a RequestModifier closure when creating requests. For example, to set the URLRequest's timeoutInterval to 120 seconds, modify the request in the closure.
var manager = Session.default
manager.request(urlString, method: method, parameters: dict, headers: headers, requestModifier: { $0.timeoutInterval = 120 }).validate().responseJSON { response in
OR
RequestModifiers also work with trailing closure syntax.
var manager = Session.default
manager.request("https://httpbin.org/get") { urlRequest in
urlRequest.timeoutInterval = 60
urlRequest.allowsConstrainedNetworkAccess = false
}
.response(...)
Try this example
String[] formats = new String[] {
"yyyy-MM-dd",
"yyyy-MM-dd HH:mm",
"yyyy-MM-dd HH:mmZ",
"yyyy-MM-dd HH:mm:ss.SSSZ",
"yyyy-MM-dd'T'HH:mm:ss.SSSZ",
};
for (String format : formats) {
SimpleDateFormat sdf = new SimpleDateFormat(format, Locale.US);
System.err.format("%30s %s\n", format, sdf.format(new Date(0)));
sdf.setTimeZone(TimeZone.getTimeZone("UTC"));
System.err.format("%30s %s\n", format, sdf.format(new Date(0)));

If you use something like Express.js and Bodyparser then it would look like this since Express will handle the request.body concatenation
var express = require('express')
var fs = require('fs')
var app = express()
app.use(express.bodyParser())
app.get('/', function(request, response) {
console.log('GET /')
var html = `
<html>
<body>
<form method="post" action="http://localhost:3000">Name:
<input type="text" name="name" />
<input type="submit" value="Submit" />
</form>
</body>
</html>`
response.writeHead(200, {'Content-Type': 'text/html'})
response.end(html)
})
app.post('/', function(request, response) {
console.log('POST /')
console.dir(request.body)
response.writeHead(200, {'Content-Type': 'text/html'})
response.end('thanks')
})
port = 3000
app.listen(port)
console.log(`Listening at http://localhost:${port}`)
Bootstrap 2
CSS solution:.collapse { transition: height 0.01s; }
NB: setting transition: none
disables the collapse functionnality.
Bootstrap 4
solution:.collapsing {
transition: none !important;

The following code will give you CPU ID:
namespace required System.Management
var mbs = new ManagementObjectSearcher("Select ProcessorId From Win32_processor");
ManagementObjectCollection mbsList = mbs.Get();
string id = "";
foreach (ManagementObject mo in mbsList)
{
id = mo["ProcessorId"].ToString();
break;
}
For Hard disk ID and motherboard id details refer this-link
To speed up this procedure, make sure you don't use SELECT *
, but only select what you really need. Use SELECT *
only during development when you try to find out what you need to use, because then the query will take much longer to complete.
var array = string.split(',')
and good morning, too, since I have to type 30 chars ...
Your query should look like
UPDATE table_name
SET column1=value, column2=value2,...
WHERE some_column=some_value
You can check the below question for help
If you can simply change the href
value, you should use:
<a href="javascript:void(0);">Link Title</a>
Another neat solution I just came up with is to use jQuery to stop the click action from occurring and causing the page to scroll, but only for href="#"
links.
<script type="text/javascript">
/* Stop page jumping when links are pressed */
$('a[href="#"]').live("click", function(e) {
return false; // prevent default click action from happening!
e.preventDefault(); // same thing as above
});
</script>
This works for me:
import com.google.common.base.Strings;
if (!Strings.isNullOrEmpty(myString)) {
return myString;
}
Returns true if the given string is null or is the empty string.
Consider normalizing your string references with nullToEmpty. If you do, you can use String.isEmpty() instead of this method, and you won't need special null-safe forms of methods like String.toUpperCase either. Or, if you'd like to normalize "in the other direction," converting empty strings to null, you can use emptyToNull.
Actually, if you don't know if the subfolders have a git repo or not, the best would be to let find
get the repos for you:
find . -type d -name .git -exec git --git-dir={} --work-tree=$PWD/{}/.. pull origin master \;
The PowerShell equivalent would be:
Get-ChildItem -Recurse -Directory -Hidden -Filter .git | ForEach-Object { & git --git-dir="$($_.FullName)" --work-tree="$(Split-Path $_.FullName -Parent)" pull origin master }
Session in Java servlets is the same as session in other languages such as PHP. It is unique to the user. The server can keep track of it in different ways such as cookies, url rewriting etc. This Java doc article explains it in the context of Java servlets and indicates that exactly how session is maintained is an implementation detail left to the designers of the server. The specification only stipulates that it must be maintained as unique to a user across multiple connections to the server. Check out this article from Oracle for more information about both of your questions.
Edit There is an excellent tutorial here on how to work with session inside of servlets. And here is a chapter from Sun about Java Servlets, what they are and how to use them. Between those two articles, you should be able to answer all of your questions.
Don't forget any?
which is generally !empty?
. In Rails I typically check for the presence of something at the end of a statement with if something
or unless something
then use blank?
where needed since it seems to work everywhere.
If you have vps or dedicated server, You can code your own module using C programming.

All answers are OK, depending on how academic you want to be. If you wish to follow the Java specifications accurately, use the following:
private static final Pattern DOUBLE_PATTERN = Pattern.compile(
"[\\x00-\\x20]*[+-]?(NaN|Infinity|((((\\p{Digit}+)(\\.)?((\\p{Digit}+)?)" +
"([eE][+-]?(\\p{Digit}+))?)|(\\.((\\p{Digit}+))([eE][+-]?(\\p{Digit}+))?)|" +
"(((0[xX](\\p{XDigit}+)(\\.)?)|(0[xX](\\p{XDigit}+)?(\\.)(\\p{XDigit}+)))" +
"[pP][+-]?(\\p{Digit}+)))[fFdD]?))[\\x00-\\x20]*");
public static boolean isFloat(String s)
{
return DOUBLE_PATTERN.matcher(s).matches();
}
This code is based on the JavaDocs at Double.
Official document of Crypto++ AES is a good start. And from my archive, a basic implementation of AES is as follows:
Please refer here with more explanation, I recommend you first understand the algorithm and then try to understand each line step by step.
#include <iostream>
#include <iomanip>
#include "modes.h"
#include "aes.h"
#include "filters.h"
int main(int argc, char* argv[]) {
//Key and IV setup
//AES encryption uses a secret key of a variable length (128-bit, 196-bit or 256-
//bit). This key is secretly exchanged between two parties before communication
//begins. DEFAULT_KEYLENGTH= 16 bytes
CryptoPP::byte key[ CryptoPP::AES::DEFAULT_KEYLENGTH ], iv[ CryptoPP::AES::BLOCKSIZE ];
memset( key, 0x00, CryptoPP::AES::DEFAULT_KEYLENGTH );
memset( iv, 0x00, CryptoPP::AES::BLOCKSIZE );
//

There are few ways to read input string from your console/keyboard. The following sample code shows how to read a string from the console/keyboard by using Java.
public class ConsoleReadingDemo {
public static void main(String[] args) {
// ====
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
System.out.print("Please enter user name : ");
String username = null;
try {
username = reader.readLine();
} catch (IOException e) {
e.printStackTrace();
}
System.out.println("You entered : " + username);
// ===== In Java 5, Java.util,Scanner is used for this purpose.
Scanner in = new Scanner(System.in);
System.out.print("Please enter user name : ");
username = in.nextLine();
System.out.println("You entered : " + username);
// ====== Java 6
Console console = System.console();
username = console.readLine("Please enter user name : ");
System.out.println("You entered : " + username);
}
}
The last part of code used java.io.Console
class. you can not get Console instance from System.console()
when running the demo code through Eclipse. Because eclipse runs your application as a background process and not as a top-level process with a system console.
I had the same problem, but the answer by Aman Aggarwal didn't work for me with a Docker container running mysql 8.X. I loged in the container
docker exec -it CONTAINER_ID bash
then log into mysql as root
mysql --user=root --password
Enter the password for root (Default is 'root') Finally Run:
ALTER USER 'username' IDENTIFIED WITH mysql_native_password BY 'password';
You're all set.
Well! I observer Heroku is famous in budding and newly born developers while AWS has advanced developer persona. DigitalOcean is also a major player in this ground. Cloudways has made it much easy to create Lamp stack in a click on DigitalOcean and AWS. Having all services and packages updates in a click is far better than doing all thing manually.

There is a conflict between your build settings and the default build settings that Cocoapods wants. To see the Cocoapods build settings, view the .xcconfig file(s) in Pods/Target Support Files/Pods-${PROJECTNAME}/ in your project. For me this file contains:
GCC_PREPROCESSOR_DEFINITIONS = $(inherited) COCOAPODS=1
HEADER_SEARCH_PATHS = "${PODS_ROOT}/Headers" "${PODS_ROOT}/Headers/Commando"
OTHER_LDFLAGS = -ObjC -framework Foundation -framework QuartzCore -framework UIKit
PODS_ROOT = ${SRCROOT}/Pods
If you are happy with the Cocoapods settings, then go to Build Settings for your project, find the appropriate setting and hit the Delete key. This will use the setting from Cocoapods.
On the other hand, if you have a custom setting that you need to use, then add $(inherited) to that setting.
Put your class name on the mat-form-field element. This works for all inputs.
I had the same issue today on windows 32 bit,with node 0.10.25, and grunt 0.4.5.
I followed dongho's answer, with just few extra steps. here are the steps I used to solve the error:
1) create your package.json
$ npm init
2) install grunt for this project, this will be installed under node_modules/. --save-dev will add this module to devDependency in your package.json
$ npm install grunt --save-dev
3) then create gruntfile.js
, with a sample code like this:
module.exports = function(grunt) {
grunt.initConfig({
jshint: {
files: ['Gruntfile.js', 'src/**/*.js', 'test/**/*.js'],
options: {
globals: {
jQuery: true
}
}
},
watch: {
files: ['<%= jshint.files %>'],
tasks: ['jshint']
}
});
grunt.loadNpmTasks('grunt-contrib-jshint');
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.registerTask('default', ['jshint']);
};
here, src/**/*.js
and test/**/*.js
should be the paths to actual JS files you are using in your project
4) run npm install grunt-contrib-jshint --save-dev
5) run npm install grunt-contrib-watch --save-dev
6) run $ grunt
Note: when you require common package like concat, uglify etc, you need to add those modules via npm install
, just the way we installed jshint and watch in step 4 & 5
Use java -cp myjar.jar com.mypackage.myClass
.
If the class is not in a package then simply java -cp myjar.jar myClass
.
If you are not within the directory where myJar.jar
is located, then you can do:
On Unix or Linux platforms:
java -cp /location_of_jar/myjar.jar com.mypackage.myClass
On Windows:
java -cp c:\location_of_jar\myjar.jar com.mypackage.myClass
There is no direct format specifier for this in the C language. Although I wrote this quick python snippet to help you understand the process step by step to roll your own.
#!/usr/bin/python
dec = input("Enter a decimal number to convert: ")
base = 2
solution = ""
while dec >= base:
solution = str(dec%base) + solution
dec = dec/base
if dec > 0:
solution = str(dec) + solution
print solution
Explained:
dec = input("Enter a decimal number to convert: ") - prompt the user for numerical input (there are multiple ways to do this in C via scanf for example)
base = 2 - specify our base is 2 (binary)
solution = "" - create an empty string in which we will concatenate our solution
while dec >= base: - while our number is bigger than the base entered
solution = str(dec%base) + solution - get the modulus of the number to the base, and add it to the beginning of our string (we must add numbers right to left using division and remainder method). the str() function converts the result of the operation to a string. You cannot concatenate integers with strings in python without a type conversion.
dec = dec/base - divide the decimal number by the base in preperation to take the next modulo
if dec > 0: solution = str(dec) + solution - if anything is left over, add it to the beginning (this will be 1, if anything)
print solution - print the final number
If the database is installed on a different machine it has probably correct version of pg_dump installed. This means that you can execute pg_dump command remotely with SSH:
ssh username@dbserver pg_dump books > books.out
You can also use public key authentication for passwordless execution. Steps to achieve that:
Sounds like a job for XMLUnit
Example:
public class SomeTest extends XMLTestCase {
@Test
public void test() {
String xml1 = ...
String xml2 = ...
XMLUnit.setIgnoreWhitespace(true); // ignore whitespace differences
// can also compare xml Documents, InputSources, Readers, Diffs
assertXMLEqual(xml1, xml2); // assertXMLEquals comes from XMLTestCase
}
}
Some databases are designed to communicate over the web using ports assigned by the Internet Assigned Number Authority (IANA) and when run on individual PC use the ports with localhost. Some common databases with their default ports (the defualts can usually be overridden):
Port Database
1433 Microsoft SQL Server https://support.microsoft.com/en-us/kb/287932
3306 MySQL https://dev.mysql.com/doc/refman/4.1/en/connecting.html
5432 PostgreSQL
1527 Apache Derby (database)
Some web servers and databases are paired together such as Apache/MySQL (as in LAMP or XXAMP) or MS Internet Information Server (IIS)/MS SQL Server (IIS/SQL Server) in which case you have to be concerned with both the port of the database and the web server -- a common example of this is WordPress which uses Apache/MySQL.
There is a subtle differences between String object and string literal.
String s = "abc"; // creates one String object and one reference variable
In this simple case, "abc" will go in the pool and s will refer to it.
String s = new String("abc"); // creates two objects,and one reference variable
In this case, because we used the new
keyword, Java will create a new String object
in normal (non-pool) memory, and s will refer to it. In addition, the literal "abc" will
be placed in the pool.
For a typical XAMPP install on windows you probably have the php_sockets.dll in your C:\xampp\php\ext directory. All you got to do is go to php.ini in the C:\xampp\php directory and change the ;extension=php_sockets.dll
to extension=php_sockets.dll
.
In Typescript 3.5+:
interface TypographyProps {
variant: string
fontSize: number
}
type TypographyPropsMinusVariant = Omit<TypographyProps, "variant">
You can use a sealed abstract class instead of the enumeration, for example:
sealed abstract class Constraint(val name: String, val verifier: Int => Boolean)
case object NotTooBig extends Constraint("NotTooBig", (_ < 1000))
case object NonZero extends Constraint("NonZero", (_ != 0))
case class NotEquals(x: Int) extends Constraint("NotEquals " + x, (_ != x))
object Main {
def eval(ctrs: Seq[Constraint])(x: Int): Boolean =
(true /: ctrs){ case (accum, ctr) => accum && ctr.verifier(x) }
def main(args: Array[String]) {
val ctrs = NotTooBig :: NotEquals(5) :: Nil
val evaluate = eval(ctrs) _
println(evaluate(3000))
println(evaluate(3))
println(evaluate(5))
}
}
a = [2 3 5];
b = [1 1 0];
c = a+b;
starts = zeros(3,3);
ends = [a;b;c];
quiver3(starts(:,1), starts(:,2), starts(:,3), ends(:,1), ends(:,2), ends(:,3))
axis equal
I had the same problem, Eclipse would not start. Found this link and it worked like a charm:
Can't click Menu Bar Items in Eclipse
Java is messed-up on Maverick, need to download and install from here: http://support.apple.com/kb/DL1572?viewlocale=en_US&locale=en_US
You just use this code

</LinearLayout>
And This is background which i used...
<?xml version="1.0" encoding="utf-8"?><shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners android:radius="5dp" />
<solid android:color="@color/colorwhite" />
In res folder select the XML file in which you want to view your images,
<ImageView
android:id="@+id/image1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/imagep1" />
Try this:
import android.support.v7.app.ActionBar;
import android.support.v7.app.AppCompatActivity;
...
ActionBar actionbar = getSupportActionBar();
actionbar.setDisplayHomeAsUpEnabled(true);
actionbar.setHomeAsUpIndicator(R.drawable.ic_launcher);
so your icon will be used for Home / back
or
import android.support.v7.app.ActionBar;
import android.support.v7.app.AppCompatActivity;
...
ActionBar actionbar = getSupportActionBar();
actionbar.setDisplayShowHomeEnabled(true);
actionbar.setIcon(R.drawable.ic_launcher);
for static icon
If you are using Angular.js then functions imbedded into HTML, such as onclick="function()" or onchange="function()". They will not register. You need to make the change events in the javascript. Such as:
$('#exampleBtn').click(function() {
function();
});
You can do:
\bjack\b.*\bjames\b|\bjames\b.*\bjack\b
>>>list(map(int, str(number))) #number is a given integer
It returns a list of all digits of number.
Turn off the JavaScript Validator in the "Builders" config for your project:
Then either restart your Eclipse or/and rename the .js to something like .js_ then back again.
If you have multiples docker containers launched, use this
$ docker rm $(docker ps -aq)
It will remove all the current dockers listed in the "ps -aq" command.

what do you mean don't want to use sed/awk for speed purposes? sed/awk are faster than the shell's while read loop for processing files.
$ sed 's/[ \t]*\*$//' file
1234567890
1234567891
$ sed 's/..\*$//' file
1234567890
1234567891
with bash shell
while read -r a b
do
echo $a
done <file
This is worked for me
$('<div>We failed</div>')
.dialog(
{
title: 'Error',
close: function(event, ui)
{
$(this).dialog("close");
$(this).remove();
}
});
Cheers!
PS: I had a somewhat similar problem and the above approach solved it.
Typeface.js and Cufon are two other interesting options. They are JavaScript components that render special font data in JSON format (which you can convert from TrueType or OpenType formats on their web sites) via the new <canvas> element in all newer browsers except Internet Explorer and via VML in Internet Explorer.
The main problem with both (as of now) is that selecting text does not work or at least works only quite awkwardly.
Still, it is very nice for headlines. Body text... I don't know.
And it's surprisingly fast.
Try this:
$('#dropDownId option').filter(':selected').text();
$('#dropDownId option').filter(':selected').val();
Stop seeding the generator every time. Pull the srand call out of the loop
"Hard Coding" means something that you want to embeded with your program or any project that can not be changed directly. For example if you are using a database server, then you must hardcode to connect your database with your project and that can not be changed by user. Because you have hard coded.
Try the reges below
new Regex(@"^\d{4}").IsMatch("6") // false
new Regex(@"^\d{4}").IsMatch("68ab") // false
new Regex(@"^\d{4}").IsMatch("1111abcdefg")
new Regex(@"^\d+").IsMatch("6") // true (any length but at least one digit)
Let me answer this question:
First of all, using annotations as our configure method is just a convenient method instead of coping the endless XML configuration file.
The @Id
annotation is inherited from javax.persistence.Id
, indicating the member field below is the primary key of current entity. Hence your Hibernate and spring framework as well as you can do some reflect
works based on this annotation. for details please check javadoc for Id
The @GeneratedValue
annotation is to configure the way of increment of the specified column(field). For example when using Mysql
, you may specify auto_increment
in the definition of table to make it self-incremental, and then use
@GeneratedValue(strategy = GenerationType.IDENTITY)
in the Java code to denote that you also acknowledged to use this database server side strategy. Also, you may change the value in this annotation to fit different requirements.
For instance, Oracle has to use sequence
as increment method, say we create a sequence in Oracle:
create sequence oracle_seq;
Now that we have the sequence in database, but we need to establish the relation between Java and DB, by using @SequenceGenerator
:
@SequenceGenerator(name="seq",sequenceName="oracle_seq")
sequenceName
is the real name of a sequence in Oracle, name
is what you want to call it in Java. You need to specify sequenceName
if it is different from name
, otherwise just use name
. I usually ignore sequenceName
to save my time.
Finally, it is time to make use this sequence in Java. Just add @GeneratedValue
:
@GeneratedValue(strategy=GenerationType.SEQUENCE, generator="seq")
The generator
field refers to which sequence generator you want to use. Notice it is not the real sequence name in DB, but the name you specified in name
field of SequenceGenerator
.
So the complete version should be like this:
public class MyTable
{
@Id
@SequenceGenerator(name="seq",sequenceName="oracle_seq")
@GeneratedValue(strategy=GenerationType.SEQUENCE, generator="seq")
private Integer pid;
}
Now start using these annotations to make your JavaWeb development easier.
FYI, this is not an answer to the post. But it may help future users who may get the error with the message:
TypeError: 'builtin_function_or_method' object is not subscriptable
In my case, it was occurred due to bad indentation.
Just indenting the line of code solved the issue.
You need to install the provisioning profile (drag and drop it into iTunes). Then drag and drop the .ipa. Ensure you device is set to sync apps, and try again.
Return min and max value in tuple:
def side_values(num_list):
results_list = sorted(num_list)
return results_list[0], results_list[-1]
somelist = side_values([1,12,2,53,23,6,17])
print(somelist)
I had the same problem. All I did to fix the issue was to modify my htacces file like this:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /crm/
Options +FollowSymLinks
RewriteCond %{HTTP_HOST} ^mywebsite.com [NC]
RewriteRule ^(.*)$ http://www.mywebsite.com/$1 [L,R=301]
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
RewriteRule ^index.php/(.*)$ [L]
</IfModule>
There's MonoDevelop, which I occasionally use when I want to do some light C# coding when in Linux. It's nothing close to VS.Net, but it works for small projects. I really don't think most of the alternatives people have listed come anywhere close to VS.Net.
When a new view is loaded in AngularJS
, Google Analytics does not count it as a new page load. Fortunately there is a way to manually tell GA to log a url as a new pageview.
_gaq.push(['_trackPageview', '<url>']);
would do the job, but how to bind that with AngularJS?
Here is a service which you could use:
(function(angular) {
angular.module('analytics', ['ng']).service('analytics', [
'$rootScope', '$window', '$location', function($rootScope, $window, $location) {
var track = function() {
$window._gaq.push(['_trackPageview', $location.path()]);
};
$rootScope.$on('$viewContentLoaded', track);
}
]);
}(window.angular));
When you define your angular module, include the analytics module like so:
angular.module('myappname', ['analytics']);
UPDATE:
You should use the new Universal Google Analytics tracking code with:
$window.ga('send', 'pageview', {page: $location.url()});
In the latest release of Google Play, Google removed the need to ask permission for internet as "most apps need it anyways nowadays". However, for users who have older versions, it is still recommended to leave the code below in your manifest
<uses-permission android:name="android.permission.INTERNET" />
Note that if the user may be in multiple zones used in the query, you may probably want to add .distinct()
. Otherwise you get one user multiple times:
users_in_zones = User.objects.filter(zones__in=[zone1, zone2, zone3]).distinct()
Now this answer is for those lost souls that got here with this problem because they force-unmounted the drive but their hard drive is NTFS Formatted. Assuming you have ntfs-3g installed (sudo apt-get install ntfs-3g).
sudo ntfs-3g /dev/hdd /mnt/mount_point -o force
Where hdd is the hard drive in question and the "/mnt/mount_point" directory exists.
NOTES: This fixed the issue on an Ubuntu 18.04 machine using NTFS drives that had their journal files reset through sudo ntfsfix /dev/hdd and unmounted by force using sudo umount -l /mnt/mount_point
Leaving my answer here in case this fix can aid anyone!
from php.net
Warning
The superglobals $_GET
and $_REQUEST
are already decoded. Using urldecode()
on an element in $_GET
or $_REQUEST
could have unexpected and dangerous results.
link: http://php.net/manual/en/function.urldecode.php
be careful.
to answer the second:
make the column unique and catch the exception if it's set to the same value.
Posting a note here for users looking into this into the future. Google's libphonenumber
is what you most likely would want to use. There is wrappers for PHP, node.js, Java, etc. to use the data which Google has been collecting and reduces the requirements for maintaining large arrays of regex patterns to apply.
If I've understood your problem correctly, there are two possible problems here:
resultset
is null
- I assume that this can't be the case as if it was you'd get an exception in your while loop and nothing would be output.resultset.getString(i++)
will get columns 1,2,3 and so on from each subsequent row.I think that the second point is probably your problem here.
Lets say you only had 1 row returned, as follows:
Col 1, Col 2, Col 3
A , B, C
Your code as it stands would only get A - it wouldn't get the rest of the columns.
I suggest you change your code as follows:
ResultSet resultset = ...;
ArrayList<String> arrayList = new ArrayList<String>();
while (resultset.next()) {
int i = 1;
while(i <= numberOfColumns) {
arrayList.add(resultset.getString(i++));
}
System.out.println(resultset.getString("Col 1"));
System.out.println(resultset.getString("Col 2"));
System.out.println(resultset.getString("Col 3"));
System.out.println(resultset.getString("Col n"));
}
Edit:
To get the number of columns:
ResultSetMetaData metadata = resultset.getMetaData();
int numberOfColumns = metadata.getColumnCount();
Because your function is an instance or non-static function you should create an object first.
Program p=new Program();
p.Add(1,1)
