foreach (GridViewRow gvr in gvMyGridView.Rows)
{
string PrimaryKey = gvMyGridView.DataKeys[gvr.RowIndex].Values[0].ToString();
}
You can use this code while doing an iteration with foreach
or for any GridView event like OnRowDataBound
.
Here you can input multiple values for DataKeyNames
by separating with comma ,
. For example, DataKeyNames="ProductID,ItemID,OrderID"
.
You can now access each of DataKeys
by providing its index like below:
string ProductID = gvMyGridView.DataKeys[gvr.RowIndex].Values[0].ToString();
string ItemID = gvMyGridView.DataKeys[gvr.RowIndex].Values[1].ToString();
string OrderID = gvMyGridView.DataKeys[gvr.RowIndex].Values[2].ToString();
You can also use Key Name instead of its index to get the values from DataKeyNames
collection like below:
string ProductID = gvMyGridView.DataKeys[gvr.RowIndex].Values["ProductID"].ToString();
string ItemID = gvMyGridView.DataKeys[gvr.RowIndex].Values["ItemID"].ToString();
string OrderID = gvMyGridView.DataKeys[gvr.RowIndex].Values["OrderID"].ToString();
Could this be a typo? (two Ps in ppasscode, intended?)
$_POST['ppasscode'];
I would make sure and do:
print_r($_POST);
and make sure the data is accurate there, and then echo out what it should look like:
echo hash('sha256', $_POST['ppasscode']);
Compare this output to what you have in the database (manually). By doing this you're exploring your possible points of failure:
You can use an auxiliary array (temp) which in indexes are numbers of main array. So the time complexity will be liner and O(n). As we want to do it without using any library, we define another array (unique) to push non-duplicate elements:
var num = [2,4,9,4,1,2,24,12,4];_x000D_
let temp = [];_x000D_
let unique = [];_x000D_
let j = 0;_x000D_
for (let i = 0; i < num.length; i++){_x000D_
if (temp[num[i]] !== 1){_x000D_
temp[num[i]] = 1;_x000D_
unique[j++] = num[i];_x000D_
}_x000D_
}_x000D_
console.log(unique);
_x000D_
I had the same problem. Microsoft.Owin.Host.SystemWeb package was installed but during the installation NuGet was not able to add the dll as a reference for some reason. Make sure your project has that reference. If not you can try to reinstall:
update-package Microsoft.Owin.Host.SystemWeb -reinstall
I had an error like below on reinstall but somehow it worked:
System call failed. (Exception from HRESULT: 0x80010100 (RPC_E_SYS_CALL_FAILED))
You Can Use
string txt = " i am a string ";
txt = txt.TrimStart().TrimEnd();
Output is "i am a string"
This loops vertically but might work for you.
int rtn = 0;
foreach(int[] L in lists){
for(int i = 0; i<L.Length;i++){
rtn = L[i];
//Do something with rtn
}
}
I faced the same issue below is the working code :
$("#test option").filter(function() {
return $(this).text() =='Ford';
}).prop("selected", true);
The answer of Pascal Thivent helped me out, too.
But if you manage your plugins within the <pluginManagement>

My operating systems course in undergrad had us building a number of subsystems for OS/161, a simple, BSD-like kernel that provides some of the basics while leaving the freedom to explore various design space decisions in implementing higher-level services.
If you are trying to use the null coalescing operator ??
in a version of PHP prior to PHP 7 you will get this error.
<?= $a ?? 2; // works in PHP 7+
<?= (!empty($a)) ? $a : 2; // All versions of PHP
A similar error can occur for nullable types, as in:
function add(?int $sum): ?int {
Which again indicates an outdated PHP version being used (either the CLI version php -v
or the webserver bound one phpinfo();
).
I had tha same problem trying to compile a lib I download from the internet. In my case, there was already a #include <cstdint>
in the code. I solved it adding a:
using std::uint32_t;
Try this one Open your projectname.csproj file its work for me.
<PackageReference Include="System.Data.SqlClient" Version="4.6.0" />
You need to add this Reference "ItemGroup" tag inside.
Normally "app" is the root of your application -- have you tried app/path/to/assets/img.png
?
You can use implicit transactions for this
SET IMPLICIT_TRANSACTIONS ON
update Staff set staff_Name='jas' where staff_id=7
ROLLBACK
As you request-- You can SET this setting ( SET IMPLICIT_TRANSACTIONS ON
) from a stored procedure by setting that stored procedure as the start up procedure.
But SET IMPLICIT TRANSACTION ON
command is connection specific. So any connection other than the one which running the start up stored procedure will not benefit from the setting you set.
Here is what worked for me.
Install the userspace USB programming library development files
sudo apt-get install libusb-1.0-0-dev
sudo updatedb && locate libusb.h
The path should appear as (or similar)
/usr/include/libusb-1.0/libusb.h
Include the header to your C code
#include <libusb-1.0/libusb.h>
Compile your C file
gcc -o example example.c -lusb-1.0
There are ALMOST only two types of JavaScript scopes:
So, any blocks other than functions do not create a new scope. That explains why for-loops overwrite outer scoped variables:
var i = 10, v = 10;
for (var i = 0; i < 5; i++) { var v = 5; }
console.log(i, v);
// output 5 5
Using functions instead:
var i = 10, v = 10;
$.each([0, 1, 2, 3, 4], function(i) { var v = 5; });
console.log(i,v);
// output 10 10
In the first example, there was no block scope, so the initially declared variables were overwritten. In the second example, there was a new scope due to the function, so the initially declared variables were SHADOWED, and not overwritten.
That's almost all you need to know in terms of JavaScript scoping, except:
So you can see JavaScript scoping is actually extremely simple, albeit not always intuitive. A few things to be aware of:
So this code:
var i = 1;
function abc() {
i = 2;
var i = 3;
}
console.log(i); // outputs 1
is equivalent to:
var i = 1;
function abc() {
var i; // var declaration moved to the top of the scope
i = 2;
i = 3; // the assignment stays where it is
}
console.log(i);
This may seem counter intuitive, but it makes sense from the perspective of a imperative language designer.
Angular < 1.6.X

Just a small correction to the first answer in this thread.
Even for Stack, you need to create new object with generics if you are using Stack from java util packages.
Right usage:
Stack<Integer> s = new Stack<Integer>();
Stack<String> s1 = new Stack<String>();
s.push(7);
s.push(50);
s1.push("string");
s1.push("stack");
if used otherwise, as mentioned in above post, which is:
/*
Stack myStack = new Stack();
// add any type of elements (String, int, etc..)
myStack.push("Hello");
myStack.push(1);
*/
Although this code works fine, has unsafe or unchecked operations which results in error.
int scrWidth = getWindowManager().getDefaultDisplay().getWidth();
int scrHeight = getWindowManager().getDefaultDisplay().getHeight();
Since I reached here while searching to join on a specific property of a list of objects (and not the ToString() of it) here's an addition to the accepted answer:
var commaDelimited = string.Join(",", students.Where(i => i.Category == studentCategory)
.Select(i => i.FirstName));
Contrary to some of the answers here, editing the stylesheet itself with Javascript is not only possible, but higher performance. Simply doing $('.myclass').css('color: red')
will end up looping through every item matching the selector and individually setting the style attribute. This is really inefficient and if you have hundreds of elements, it's going to cause problems.
Changing classes on the items is a better idea, but you still suffer from the same problem in that you're changing an attribute on N items, which could be a large number. A better solution might be to change the class on one single parent item or a small number of parents and then hit the target items using the "Cascade" in css. This serves in most situations, but not all.
Sometimes you need to change the CSS of a lot of items to something dynamic, or there's no good way for you to do so by hitting a small number of parents. Changing the stylesheet itself, or adding a small new one to override the existing css is an extremely efficient way to change the display of items. You're only interacting with the DOM in one spot and the browser can handle deploying those changes really efficiently.
jss is one library that helps make it easier to directly edit the stylesheet from javascript.
On Linux Mint 18 the default config file that has the sql-mode
option set is located here :
/usr/my.cnf
And relevant line is:
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
So You can set there.
If not sure what config file has such option You can search for it:
$ sudo find / -iname "*my.cnf*"
And get a list:
/var/lib/dpkg/alternatives/my.cnf
/usr/my.cnf
/etc/alternatives/my.cnf
/etc/mysql/my.cnf.fallback
/etc/mysql/my.cnf
Offline mode could be set in Android Studio and in your project. To verify that gradle won't build your project in offline mode:
You can also get by phpPgAdmin if you are configured it in your system,
Step 1: Select your database
Step 2: Click on find button
Step 3: Change search option to functions then click on Find.
You will get the list of defined functions.You can search functions by name also, hope this answer will help others.
You will first need to create a custom layout xml which will represent a single item in your list. You will add your two buttons to this layout along with any other items you want to display from your list.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="@+id/list_item_string"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_alignParentLeft="true"
android:paddingLeft="8dp"
android:textSize="18sp"
android:textStyle="bold" />
<Button
android:id="@+id/delete_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="5dp"
android:text="Delete" />
<Button
android:id="@+id/add_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toLeftOf="@id/delete_btn"
android:layout_centerVertical="true"
android:layout_marginRight="10dp"
android:text="Add" />
</RelativeLayout>
Next you will need to create a Custom ArrayAdapter Class which you will use to inflate your xml layout, as well as handle your buttons and on click events.
public class MyCustomAdapter extends BaseAdapter implements ListAdapter {
private ArrayList<String> list = new ArrayList<String>();
private Context context;
public MyCustomAdapter(ArrayList<String> list, Context context) {
this.list = list;
this.context = context;
}
@Override
public int getCount() {
return list.size();
}
@Override
public Object getItem(int pos) {
return list.get(pos);
}
@Override
public long getItemId(int pos) {
return list.get(pos).getId();
//just return 0 if your list items do not have an Id variable.
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
View view = convertView;
if (view == null) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.my_custom_list_layout, null);
}
//Handle TextView and display string from your list
TextView listItemText = (TextView)view.findViewById(R.id.list_item_string);
listItemText.setText(list.get(position));
//Handle buttons and add onClickListeners
Button deleteBtn = (Button)view.findViewById(R.id.delete_btn);
Button addBtn = (Button)view.findViewById(R.id.add_btn);
deleteBtn.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
//do something
list.remove(position); //or some other task
notifyDataSetChanged();
}
});
addBtn.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
//do something
notifyDataSetChanged();
}
});
return view;
}
}
Finally, in your activity you can instantiate your custom ArrayAdapter class and set it to your listview.
public class MyActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my_activity);
//generate list
ArrayList<String> list = new ArrayList<String>();
list.add("item1");
list.add("item2");
//instantiate custom adapter
MyCustomAdapter adapter = new MyCustomAdapter(list, this);
//handle listview and assign adapter
ListView lView = (ListView)findViewById(R.id.my_listview);
lView.setAdapter(adapter);
}
Hope this helps!
git log --oneline --decorate --all --graph
A visual tree with branch names included.

Add your image path like fullPathname='assets/images/therealdealportfoliohero.jpg'

If you don't want a timeout happening for some purpose:
<session-config>
<session-timeout>0</session-timeout>
</session-config>
Should result in no timeout at all -> infinite
Hi Just addition to VonC comments. I am using ecj compiler to compile my project. it was throwing expcetion that some of the classes are not found. But the project was bulding fine with javac compiler.
So just I added the classes into the classpath(which we have to pass as argument) and now its working fine... :)

How to do it with Oracle SQL Developer: In the Left pane, under the connections you will find "Sequences", right click and select create a new sequence from the context sensitive pop up. Fill out the details: Schema name, sequence_name, properties(start with value, min value, max value, increment value etc.) and click ok. Assuming that you have a table with a key that uses this auto_increment, while inserting in this table just give "your_sequence_name.nextval" in the field that utilizes this property. I guess this should help! :)
In jQuery just use:
$('#tblOne > tbody > tr').each(function() {...code...});
Using the children selector (>
) you will walk over all the children (and not all descendents), example with three rows:
$('table > tbody > tr').each(function(index, tr) {
console.log(index);
console.log(tr);
});
Result:
0
<tr>
1
<tr>
2
<tr>
In VanillaJS you can use document.querySelectorAll()
and walk over the rows using forEach()
[].forEach.call(document.querySelectorAll('#tblOne > tbody > tr'), function(index, tr) {
/* console.log(index); */
/* console.log(tr); */
});
The most important difference is that robocopy
will (usually) retry when an error occurs, while xcopy
will not. In most cases, that makes robocopy
far more suitable for use in a script.
Addendum: for completeness, there is one known edge case issue with robocopy; it may silently fail to copy files or directories whose names contain invalid UTF-16 sequences. If that's a problem for you, you may need to look at third-party tools, or write your own.
To get more information use this custom TO($someObject) function:
I wrote this simple function which not only displays the methods of a given object, but also shows its properties, encapsulation and some other useful information like release notes if given.
function TO($object){ //Test Object
if(!is_object($object)){
throw new Exception("This is not a Object");
return;
}
if(class_exists(get_class($object), true)) echo "<pre>CLASS NAME = ".get_class($object);
$reflection = new ReflectionClass(get_class($object));
echo "<br />";
echo $reflection->getDocComment();
echo "<br />";
$metody = $reflection->getMethods();
foreach($metody as $key => $value){
echo "<br />". $value;
}
echo "<br />";
$vars = $reflection->getProperties();
foreach($vars as $key => $value){
echo "<br />". $value;
}
echo "</pre>";
}
To show you how it works I will create now some random example class. Lets create class called Person and lets place some release notes just above the class declaration:
/**
* DocNotes - This is description of this class if given else it will display false
*/
class Person{
private $name;
private $dob;
private $height;
private $weight;
private static $num;
function __construct($dbo, $height, $weight, $name) {
$this->dob = $dbo;
$this->height = (integer)$height;
$this->weight = (integer)$weight;
$this->name = $name;
self::$num++;
}
public function eat($var="", $sar=""){
echo $var;
}
public function potrzeba($var =""){
return $var;
}
}
Now lets create a instance of a Person and wrap it with our function.
$Wictor = new Person("27.04.1987", 170, 70, "Wictor");
TO($Wictor);
This will output information about the class name, parameters and methods including encapsulation information and the number of parameters, names of parameters for each method, method location and lines of code where it exists. See the output below:
CLASS NAME = Person
/**
* DocNotes - This is description of this class if given else it will display false
*/

First you need to define a LocationListener
to handle location changes.
private final LocationListener mLocationListener = new LocationListener() {
@Override
public void onLocationChanged(final Location location) {
//your code here
}
};
Then get the LocationManager
and ask for location updates
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mLocationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, LOCATION_REFRESH_TIME,
LOCATION_REFRESH_DISTANCE, mLocationListener);
}
And finally make sure that you have added the permission on the Manifest,
For using only network based location use this one
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
For GPS based location, this one
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
This is a more generic solution, that can be use for any Enum object, so be free of used.
static public List<Object> constFromEnumToList(Class enumType) {
List<Object> nueva = new ArrayList<Object>();
if (enumType.isEnum()) {
try {
Class<?> cls = Class.forName(enumType.getCanonicalName());
Object[] consts = cls.getEnumConstants();
nueva.addAll(Arrays.asList(consts));
} catch (ClassNotFoundException e) {
System.out.println("No se localizo la clase");
}
}
return nueva;
}
Now you must call this way:
constFromEnumToList(MiEnum.class);
based on graycrow's excellent answer...
Here's a more real world example that has two cicular divs with some filler content. I replaced the hard-coded png background with just a hex value, i.e.

BTW, HTTP 1/1 specification (RFC2616) suggests no more than 2 connections per server.
Clients that use persistent connections SHOULD limit the number of simultaneous connections that they maintain to a given server. A single-user client SHOULD NOT maintain more than 2 connections with any server or proxy. A proxy SHOULD use up to 2*N connections to another server or proxy, where N is the number of simultaneously active users. These guidelines are intended to improve HTTP response times and avoid congestion.
First install newtonsoft.json
package to Visual Studio
using NuGet Package Manager
then add the following code:

It allows servlets to have multiple servlet mappings:
<servlet>
<servlet-name>Servlet1</servlet-name>
<servlet-path>foo.Servlet</servlet-path>
</servlet>
<servlet-mapping>
<servlet-name>Servlet1</servlet-name>
<url-pattern>/enroll</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Servlet1</servlet-name>
<url-pattern>/pay</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Servlet1</servlet-name>
<url-pattern>/bill</url-pattern>
</servlet-mapping>
It allows filters to be mapped on the particular servlet:
<filter-mapping>
<filter-name>Filter1</filter-name>
<servlet-name>Servlet1</servlet-name>
</filter-mapping>
Your proposal would support neither of them. Note that the web.xml
is read and parsed only once during application's startup, not on every HTTP request as you seem to think.
Since Servlet 3.0, there's the @WebServlet
annotation which minimizes this boilerplate:
@WebServlet("/enroll")
public class Servlet1 extends HttpServlet {
The best explanation of how core.autocrlf
works is found on the gitattributes man page, in the text
attribute section.
This is how core.autocrlf
appears to work currently (or at least since v1.7.2 from what I am aware):
core.autocrlf = true
LF
characters are normalized to CRLF
in your working tree; files that contain CRLF
in the repository will not be touchedLF
characters in the repository, are normalized from CRLF
to LF
when committed back to the repository. Files that contain CRLF
in the repository will be committed untouched.core.autocrlf = input
CRLF
characters are normalized to LF
when committed back to the repository.core.autocrlf = false
core.eol
dictates EOL characters in the text files of your working tree.core.eol = native
by default, which means Windows EOLs are CRLF
and *nix EOLs are LF
in working trees.gitattributes
settings determines EOL character normalization for commits to the repository (default is normalization to LF
characters).I've only just recently researched this issue and I also find the situation to be very convoluted. The core.eol
setting definitely helped clarify how EOL characters are handled by git.
Based on http://code.msdn.microsoft.com/101-LINQ-Samples-3fb9811b,
EqualAll is the approach that best meets your needs.
public void Linq96()
{
var wordsA = new string[] { "cherry", "apple", "blueberry" };
var wordsB = new string[] { "cherry", "apple", "blueberry" };
bool match = wordsA.SequenceEqual(wordsB);
Console.WriteLine("The sequences match: {0}", match);
}
I've encountered the same problem. Amith GC's answer(the first answer checked as accepted) is right, but sometimes textview.setSelected(true); doesn't work when the text view can't get the focus all the time. So, to ensure TextView Marquee working, I had to use a custom TextView.
public class CustomTextView extends TextView {
public CustomTextView(Context context) {
super(context);
}
public CustomTextView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public CustomTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
@Override
protected void onFocusChanged(boolean focused, int direction, Rect previouslyFocusedRect) {
if(focused)
super.onFocusChanged(focused, direction, previouslyFocusedRect);
}
@Override
public void onWindowFocusChanged(boolean focused) {
if(focused)
super.onWindowFocusChanged(focused);
}
@Override
public boolean isFocused() {
return true;
}
}
And then, you can use the custom TextView as the scrolling text view in your layout .xml file like this:
<com.example.myapplication.CustomTextView
android:id="@+id/tvScrollingMessage"
android:text="@string/scrolling_message_main_wish_list"
android:singleLine="true"
android:ellipsize="marquee"
android:marqueeRepeatLimit ="marquee_forever"
android:focusable="true"
android:focusableInTouchMode="true"
android:scrollHorizontally="true"
android:layout_width="match_parent"
android:layout_height="40dp"
android:background="@color/black"
android:gravity="center"
android:textColor="@color/white"
android:textSize="15dp"
android:freezesText="true"/>
NOTE: in the above code snippet com.example.myapplication is an example package name and should be replaced by your own package name.
Hope this will help you. Cheers!

So, your checkbox changes the testb
inside of the child scope, but not the outer parent scope.
Note, that if you want to modify the data in the parent scope, you'll need to modify the internal properties of an object like in the last div that I added.
Check the below code:
Swift 1.2
let paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as String
let getImagePath = paths.stringByAppendingPathComponent("SavedFile.jpg")
let checkValidation = NSFileManager.defaultManager()
if (checkValidation.fileExistsAtPath(getImagePath))
{
println("FILE AVAILABLE");
}
else
{
println("FILE NOT AVAILABLE");
}
Swift 2.0
let paths = NSURL(fileURLWithPath: NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0])
let getImagePath = paths.URLByAppendingPathComponent("SavedFile.jpg")
let checkValidation = NSFileManager.defaultManager()
if (checkValidation.fileExistsAtPath("\(getImagePath)"))
{
print("FILE AVAILABLE");
}
else
{
print("FILE NOT AVAILABLE");
}
In the real world, scenario its not about calling a simple function but a function with a proper value. So let's dive in. This is the scenario A user has a requirement to fire an event from his own component and also at the end he wants to call a function of another component as well. Let's say the service file is the same for both the components
componentOne.html
<button (click)="savePreviousWorkDetail()" data-dismiss="modal" class="btn submit-but" type="button">
Submit
</button>
When the user clicks on the submit button he needs to call savePreviousWorkDetail() in its own component componentOne.ts and in the end he needs to call a function of another component as well. So to do that a function in a service class can be called from componentOne.ts and when that called, the function from componentTwo will be fired.
componentOne.ts
constructor(private httpservice: CommonServiceClass) {
}
savePreviousWorkDetail() {
// Things to be Executed in this function
this.httpservice.callMyMethod("Niroshan");
}
commontServiceClass.ts
import {Injectable,EventEmitter} from '@angular/core';
@Injectable()
export class CommonServiceClass{
invokeMyMethod = new EventEmitter();
constructor(private http: HttpClient) {
}
callMyMethod(params: any = 'Niroshan') {
this.invokeMyMethod.emit(params);
}
}
And Below is the componentTwo which has the function that needed to be called from componentOne. And in ngOnInit() we have to subscribe for the invoked method so when it triggers methodToBeCalled() will be called
componentTwo.ts
import {Observable,Subscription} from 'rxjs';
export class ComponentTwo implements OnInit {
constructor(private httpservice: CommonServiceClass) {
}
myMethodSubs: Subscription;
ngOnInit() {
this.myMethodSubs = this.httpservice.invokeMyMethod.subscribe(res => {
console.log(res);
this.methodToBeCalled();
});
methodToBeCalled(){
//what needs to done
}
}
}
Maybe you could use your own "today()" method that you will patch where needed. Example with mocking utcnow() can be found here: https://bitbucket.org/k_bx/blog/src/tip/source/en_posts/2012-07-13-double-call-hack.rst?at=default
for FULLSCREEN width table:
table width MUST be 100%
if need N colunms, then THs MUST be N+1

The error you mean is due to missing additional include path. Try adding it with: INCLUDEPATH += C:\path\to\include\files\ Hope it works. Regards.
One other option that hasn't been mentioned yet: use Groovy. Groovy allows you to access private instance variables as a side effect of the design of the language. Whether or not you have a getter for the field, you can just use
def obj = new IWasDesignedPoorly()
def hashTable = obj.getStuffIWant()
To build on AlfredBr's answer, if you hid some of your columns, you can use the following to auto-size all columns and then just have the last visible column fill the empty space:
myDgv.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCells;
myDgv.Columns.GetLastColumn(DataGridViewElementStates.Visible, DataGridViewElementStates.None).AutoSizeMode =
DataGridViewAutoSizeColumnMode.Fill;
You could use something like this:
Private Sub PrintTableOrView(ByVal table As DataTable, ByVal label As String)
Dim sw As System.IO.StringWriter
Dim output As String
Console.WriteLine(label)
' Loop through each row in the table. '
For Each row As DataRow In table.Rows
sw = New System.IO.StringWriter
' Loop through each column. '
For Each col As DataColumn In table.Columns
' Output the value of each column's data.
sw.Write(row(col).ToString() & ", ")
Next
output = sw.ToString
' Trim off the trailing ", ", so the output looks correct. '
If output.Length > 2 Then
output = output.Substring(0, output.Length - 2)
End If
' Display the row in the console window. '
Console.WriteLine(output)
Next
Console.WriteLine()
End Sub
I guess you are looking for brace expansion:
cp /home/ankur/folder/{file1,file2} /home/ankur/dest
take a look here, it would be helpful for you if you want to handle multiple files once :
http://www.tldp.org/LDP/abs/html/globbingref.html
If your function really takes vector<int> *
(a pointer to vector), then you should pass &foo
since that will be a pointer to the vector. Obviously that will not simply solve your problem, but you cannot directly convert an iterator to a vector, since the memory at the address of the iterator will not directly address a valid vector.
You can construct a new vector by calling the vector constructor:
template <class InputIterator> vector(InputIterator, InputIterator)
This constructs a new vector by copying the elements between the two iterators. You would use it roughly like this:
bar(std::vector<int>(foo.begin()+1, foo.end());
var last = objList.LastOrDefault();
foreach (var item in objList)
{
if (item.Equals(last))
{
}
}
If you want to remove only the last newline, pipe through:
sed -z '$ s/\n$//'
sed
won't add a \0
to then end of the stream if the delimiter is set to NUL
via -z
, whereas to create a POSIX text file (defined to end in a \n
), it will always output a final \n
without -z
.
Eg:
$ { echo foo; echo bar; } | sed -z '$ s/\n$//'; echo tender
foo
bartender
And to prove no NUL
added:
$ { echo foo; echo bar; } | sed -z '$ s/\n$//' | xxd
00000000: 666f 6f0a 6261 72 foo.bar
To remove multiple trailing newlines, pipe through:
sed -Ez '$ s/\n+$//'
Necromancing.
I think the answers to date are a little unclear.
Let's make an example:
Supposed you have an array of pixels (array of ARGB int8_t values)
// A RGB image
int8_t* pixels = new int8_t[1024*768*4];
Now you want to generate a PNG. To do so, you call the function toJpeg
bool ok = toJpeg(writeByte, pixels, width, height);
where writeByte is a callback-function
void writeByte(unsigned char oneByte)
{
fputc(oneByte, output);
}
The problem here: FILE* output has to be a global variable.
Very bad if you're in a multithreaded environment (e.g. a http-server).
So you need some way to make output a non-global variable, while retaining the callback signature.
The immediate solution that springs into mind is a closure, which we can emulate using a class with a member function.
class BadIdea {
private:
FILE* m_stream;
public:
BadIdea(FILE* stream) {
this->m_stream = stream;
}
void writeByte(unsigned char oneByte){
fputc(oneByte, this->m_stream);
}
};
And then do
FILE *fp = fopen(filename, "wb");
BadIdea* foobar = new BadIdea(fp);
bool ok = TooJpeg::writeJpeg(foobar->writeByte, image, width, height);
delete foobar;
fflush(fp);
fclose(fp);
However, contrary to expectations, this does not work.
The reason is, C++ member functions are kinda implemented like C# extension functions.
So you have
class/struct BadIdea
{
FILE* m_stream;
}
and
static class BadIdeaExtensions
{
public static writeByte(this BadIdea instance, unsigned char oneByte)
{
fputc(oneByte, instance->m_stream);
}
}
So when you want to call writeByte, you need pass not only the address of writeByte, but also the address of the BadIdea-instance.
So when you have a typedef for the writeByte procedure, and it looks like this
typedef void (*WRITE_ONE_BYTE)(unsigned char);
And you have a writeJpeg signature that looks like this
bool writeJpeg(WRITE_ONE_BYTE output, uint8_t* pixels, uint32_t
width, uint32_t height))
{ ... }
it's fundamentally impossible to pass a two-address member function to a one-address function pointer (without modifying writeJpeg), and there's no way around it.
The next best thing that you can do in C++, is using a lambda-function:
FILE *fp = fopen(filename, "wb");
auto lambda = [fp](unsigned char oneByte) { fputc(oneByte, fp); };
bool ok = TooJpeg::writeJpeg(lambda, image, width, height);
However, because lambda is doing nothing different, than passing an instance to a hidden class (such as the "BadIdea"-class), you need to modify the signature of writeJpeg.
The advantage of lambda over a manual class, is that you just need to change one typedef
typedef void (*WRITE_ONE_BYTE)(unsigned char);
to
using WRITE_ONE_BYTE = std::function<void(unsigned char)>;
And then you can leave everything else untouched.
You could also use std::bind
auto f = std::bind(&BadIdea::writeByte, &foobar);
But this, behind the scene, just creates a lambda function, which then also needs the change in typedef.
So no, there is no way to pass a member function to a method that requires a static function-pointer.
But lambdas are the easy way around, provided that you have control over the source.
Otherwise, you're out of luck.
There's nothing you can do with C++.
Note:
std::function requires #include <functional>
However, since C++ allows you to use C as well, you can do this with libffcall in plain C, if you don't mind linking a dependency.
Download libffcall from GNU (at least on ubuntu, don't use the distro-provided package - it is broken), unzip.
./configure
make
make install
gcc main.c -l:libffcall.a -o ma
main.c:
#include <callback.h>
// this is the closure function to be allocated
void function (void* data, va_alist alist)
{
int abc = va_arg_int(alist);
printf("data: %08p\n", data); // hex 0x14 = 20
printf("abc: %d\n", abc);
// va_start_type(alist[, return_type]);
// arg = va_arg_type(alist[, arg_type]);
// va_return_type(alist[[, return_type], return_value]);
// va_start_int(alist);
// int r = 666;
// va_return_int(alist, r);
}
int main(int argc, char* argv[])
{
int in1 = 10;
void * data = (void*) 20;
void(*incrementer1)(int abc) = (void(*)()) alloc_callback(&function, data);
// void(*incrementer1)() can have unlimited arguments, e.g. incrementer1(123,456);
// void(*incrementer1)(int abc) starts to throw errors...
incrementer1(123);
// free_callback(callback);
return EXIT_SUCCESS;
}
And if you use CMake, add the linker library after add_executable
add_library(libffcall STATIC IMPORTED)
set_target_properties(libffcall PROPERTIES
IMPORTED_LOCATION /usr/local/lib/libffcall.a)
target_link_libraries(BitmapLion libffcall)
or you could just dynamically link libffcall
target_link_libraries(BitmapLion ffcall)
Note:
You might want to include the libffcall headers and libraries, or create a cmake project with the contents of libffcall.
Since you are in a controller, the action method is given a Request
parameter.
You can access all POST data with $request->request->all();
.
This returns a key-value pair array.
When using GET requests you access data using $request->query->all();
corrcoef
returns the normalised covariance matrix.
The covariance matrix is the matrix
Cov( X, X ) Cov( X, Y )
Cov( Y, X ) Cov( Y, Y )
Normalised, this will yield the matrix:
Corr( X, X ) Corr( X, Y )
Corr( Y, X ) Corr( Y, Y )
correlation1[0, 0 ]
is the correlation between Strategy1Returns
and itself, which must be 1. You just want correlation1[ 0, 1 ]
.
You can create a folder with os.makedirs()
and use os.path.exists() to see if it already exists:
newpath = r'C:\Program Files\arbitrary'
if not os.path.exists(newpath):
os.makedirs(newpath)
If you're trying to make an installer: Windows Installer does a lot of work for you.
Got so many errors related to permissions and what not. You may wanna try this :
xcode-select --install
I'm not sure how FWIX.com is doing it specifically, but I'd wager they are using Custom Overlays.
you need to run something like this
GRANT Execute ON [dbo].fnc_whatEver TO [domain\user]
The real solution that I found for this issue was by disabling any XML Format post processors. I have added a post processor called "jp@gc - XML Format Post Processor
" and started noticing the error "Fatal Error :1:1: Content is not allowed in prolog
"
By disabling the post processor had stopped throwing those errors.

Great collection of answers, would like to add that you can also do this using the :placeholder-shown
CSS selector. A little cleaner to use IMO, especially if you're already using jQ and have placeholders on your inputs.
if ($('input#cust-descrip').is(':placeholder-shown')) {_x000D_
console.log('Empty');_x000D_
}_x000D_
_x000D_
$('input#cust-descrip').on('blur', '', function(ev) {_x000D_
if (!$('input#cust-descrip').is(':placeholder-shown')) {_x000D_
console.log('Has Text!');_x000D_
}_x000D_
else {_x000D_
console.log('Empty!');_x000D_
}_x000D_
});
_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
_x000D_
<input type="text" class="form-control" id="cust-descrip" autocomplete="off" placeholder="Description">
_x000D_
You can also make use of the :valid
and :invalid
selectors if you have inputs that are required. You can use these selectors if you are using the required attribute on an input.
In my case the thing that was messing with I would expect was that I was missing this line:
stackView.translatesAutoresizingMaskIntoConstraints = false;
After that no need to set constraints to my arranged subviews whatsoever, the stackview is taking care of that.
The awk is ok. I'm guessing the file is from a windows system and has a CR (^m ascii 0x0d) on the end of the line.
This will cause the cursor to go to the start of the line after $2.
Use dos2unix or vi with :se ff=unix
to get rid of the CRs.

I was getting the above mentioned error message when I tried to push my current branch foobar

It turns out I had two local branches tracking the same remote branch:

foobar -> origin/foo (my current working branch)
It worked for me to push my current branch by using:
git push origin foobar:foo
... and to cleanup with git branch -d
Pecl PDO package is now deprecated. By the way the debian package php5-pgsql now includes both the regular and the PDO driver, so just:
apt-get install php-pgsql
Apache also needs to be restarted before sites can use it:

For Swift 3+ and Xcode 9+ Try using this
extension ViewController: UICollectionViewDelegateFlowLayout {
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
let collectionWidth = collectionView.bounds.width
return CGSize(width: collectionWidth/3, height: collectionWidth/3)
}
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumLineSpacingForSectionAt section: Int) -> CGFloat {
return 0
}
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumInteritemSpacingForSectionAt section: Int) -> CGFloat {
return 0
}
Works that way as well, a bit more tidy.
getQuery()
just returns the underlying builder, which already contains the table reference.
$browser_total_raw = DB::raw('count(*) as total');
$user_info = Usermeta::getQuery()
->select('browser', $browser_total_raw)
->groupBy('browser')
->pluck('total','browser');

C++17 (N4659
) includes a proposal Refining Expression Evaluation Order for Idiomatic C++
which defines a stricter order of expression evaluation.
In particular, the following sentence
8.18 Assignment and compound assignment operators:
....In all cases, the assignment is sequenced after the value computation of the right and left operands, and before the value computation of the assignment expression. The right operand is sequenced before the left operand.
together with the following clarification
An expression X is said to be sequenced before an expression Y if every value computation and every side effect associated with the expression X is sequenced before every value computation and every side effect associated with the expression Y.
make several cases of previously undefined behavior valid, including the one in question:
a[++i] = i;
However several other similar cases still lead to undefined behavior.
In N4140
:
i = i++ + 1; // the behavior is undefined
But in N4659
i = i++ + 1; // the value of i is incremented
i = i++ + i; // the behavior is undefined
Of course, using a C++17 compliant compiler does not necessarily mean that one should start writing such expressions.
As another answer alludes to under newer versions of Windows it seems to be necessary to read the standard output and/or standard error streams otherwise it will stall between commands. A neater way to do that instead of using delays is to use an async callback to consume output from the stream:
static void RunCommands(List<string> cmds, string workingDirectory = "")
{
var process = new Process();
var psi = new ProcessStartInfo();
psi.FileName = "cmd.exe";
psi.RedirectStandardInput = true;
psi.RedirectStandardOutput = true;
psi.RedirectStandardError = true;
psi.UseShellExecute = false;
psi.WorkingDirectory = workingDirectory;
process.StartInfo = psi;
process.Start();
process.OutputDataReceived += (sender, e) => { Console.WriteLine(e.Data); };
process.ErrorDataReceived += (sender, e) => { Console.WriteLine(e.Data); };
process.BeginOutputReadLine();
process.BeginErrorReadLine();
using (StreamWriter sw = process.StandardInput)
{
foreach (var cmd in cmds)
{
sw.WriteLine (cmd);
}
}
process.WaitForExit();
}
You can also use Uploadify, which is a great jQuery upload plugin, it let's you upload multiple files, and also style the file fields easily. http://www.uploadify.com
You are more vulnerable to attacks if using eval
: JSON is a subset of Javascript and json.parse just parses JSON whereas eval
would leave the door open to all JS expressions.
For Python 3xx:
import time
for i in range(10):
time.sleep(0.2)
print ("\r Loading... {}".format(i)+str(i), end="")
You can generate a XmlHttpRequest and request the page,and then use getResponseText() to get the content.
Here are a few resources you might consider: Creating Zip archives in .NET (without an external library like SharpZipLib)
Zip Your Streams with System.IO.Packaging
My recommendation and preference would be to use system.io.packacking. This keeps your dependencies down (just the framework). Jgalloway’s post (the first reference) provides a good example of adding two files to a zip file. Yes, it is more verbose, but you can easily create a façade (to a degree his AddFileToZip does that).

These solutions are pretty good, but they are forgetting that there may be other status codes than 200 OK. This is a solution that I've used on production environments for status monitoring and such.
If there is a url redirect or some other condition on the target page, the return will be true using this method. Also, GetResponse() will throw an exception and hence you will not get a StatusCode for it. You need to trap the exception and check for a ProtocolError.
Any 400 or 500 status code will return false. All others return true. This code is easily modified to suit your needs for specific status codes.
/// <summary>
/// This method will check a url to see that it does not return server or protocol errors
/// </summary>
/// <param name="url">The path to check</param>
/// <returns></returns>

request.Timeout = 5000; //set the timeout to 5 seconds to keep the user from waiting too long for the page to load
request.Method = "HEAD"; //Get only the header information -- no need to download any content
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
int statusCode = (int)response.StatusCode;
if (statusCode >= 100 && statusCode < 400) //Good requests
{
return true;
}
else if (statusCode >= 500 && statusCode <= 510) //Server Errors

//log.Warn(String.Format("The remote server has thrown an internal error. Url is not valid: {0}", url));
Debug.WriteLine(String.Format("The remote server has thrown an internal error. Url is not valid: {0}", url));
return false;

Seeing as everyone seems to get directed here for this issue, I'm adding my answer to a similar question, which contains the same code as this answer but with full background for those who are interested:
IE's document.selection.createRange doesn't include leading or trailing blank lines
To account for trailing line breaks is tricky in IE, and I haven't seen any solution that does this correctly, including any other answers to this question. It is possible, however, using the following function, which will return you the start and end of the selection (which are the same in the case of a caret) within a <textarea>
or text <input>
.
Note that the textarea must have focus for this function to work properly in IE. If in doubt, call the textarea's focus()
method first.
function getInputSelection(el) {
var start = 0, end = 0, normalizedValue, range,
textInputRange, len, endRange;
if (typeof el.selectionStart == "number" && typeof el.selectionEnd == "number") {
start = el.selectionStart;
end = el.selectionEnd;
} else {
range = document.selection.createRange();
if (range && range.parentElement() == el) {
len = el.value.length;
normalizedValue = el.value.replace(/\r\n/g, "\n");
// Create a working TextRange that lives only in the input
textInputRange = el.createTextRange();
textInputRange.moveToBookmark(range.getBookmark());
// Check if the start and end of the selection are at the very end
// of the input, since moveStart/moveEnd doesn't return what we want
// in those cases
endRange = el.createTextRange();
endRange.collapse(false);
if (textInputRange.compareEndPoints("StartToEnd", endRange) > -1) {
start = end = len;
} else {
start = -textInputRange.moveStart("character", -len);
start += normalizedValue.slice(0, start).split("\n").length - 1;
if (textInputRange.compareEndPoints("EndToEnd", endRange) > -1) {
end = len;
} else {
end = -textInputRange.moveEnd("character", -len);
end += normalizedValue.slice(0, end).split("\n").length - 1;
}
}
}
}
return {
start: start,
end: end
};
}
You could change the database structure such that all subject rows become a column variable (like spreadsheet). This makes such analysis much easier
If your text will be consumed by non-browsers then it's safer to type the character with the keyboard-combo option shift right bracket
because ’
will not be transformed into an apostrophe by a regular XML or JSON parser. (e.g. if you are serving this content to native Android/iOS apps).
The class DailyRollingFileAppender
uses the DatePattern option to specify the rolling schedule. This pattern should follow the SimpleDateFormat
conventions from Std. Ed. v1.4.2. So, we have to use E
option (Day in week). For example:
<param name="DatePattern" value="'.'EEE"/>
See more about DailyRollingFileAppender
class from log4j
javadoc here. Unfortunately the Java 1.4.2 documentation is no longer online, but you can download a copy here.
Add
import {withRouter} from 'react-router-dom';
Then change your component export
export default withRouter(ComponentName)
Then you can access the route directly within the component itself (without touching anything else in your project) using:
window.location.pathname
Tested March 2020 with: "version": "5.1.2"
This can be something to start with:
import configparser
config = configparser.ConfigParser()
config.read('FILE.INI')
print(config['DEFAULT']['path']) # -> "/path/name/"
config['DEFAULT']['path'] = '/var/shared/' # update
config['DEFAULT']['default_message'] = 'Hey! help me!!' # create
with open('FILE.INI', 'w') as configfile: # save
config.write(configfile)
You can find more at the official configparser documentation.
function escapeRegExp(string) {
return string.replace(/[.*+?^${}()|[\]\\]/g, '\\$&'); // $& means the whole matched string
}

escapeRegExp("All of these should be escaped: \ ^ $ * + ? . ( ) | { } [ ]");
>>> "All of these should be escaped: \\ \^ \$ \* \+ \? \. \( \) \| \{ \} \[ \] "
(NOTE: the above is not the original answer; it was edited to show the one from MDN. This means it does not match what you will find in the code in the below npm, and does not match what is shown in the below long answer. The comments are also now confusing. My recommendation: use the above, or get it from MDN, and ignore the rest of this answer. -Darren,Nov 2019)

Just make your Add

by adding the static
keyword like this:
public static int Add(int x, int y)
This is an Oracle-specific notation for an outer join. It means that it will include all rows from t1, and use NULLS in the t0 columns if there is no corresponding row in t0.
In standard SQL one would write:
SELECT t0.foo, t1.bar
FROM FIRST_TABLE t0
RIGHT OUTER JOIN SECOND_TABLE t1;
Oracle recommends not to use those joins anymore if your version supports ANSI joins (LEFT/RIGHT JOIN) :
Oracle recommends that you use the FROM clause OUTER JOIN syntax rather than the Oracle join operator. Outer join queries that use the Oracle join operator (+) are subject to the following rules and restrictions […]
Well maybe you forgot to add "$route" when declaring the dependencies of your Controller:
app.controller('NameCtrl', ['$scope','$route', function($scope,$route) {
// $route.reload(); Then this should work fine.
}]);
This is for Mac OS X with the native installation of Apache HTTP and custom installation of MySQL.
The answer is based on @alec-gorge's excellent response, but since I had to google some specific changes to have it configured in my configuration, mostly Mac OS X-specific, I thought I'd add it here for the sake of completeness.
Make sure the PHP5 support is enabled in /etc/apache2/httpd.conf
.
Edit the file with sudo vi /etc/apache2/httpd.conf
(enter the password when asked) and uncomment (remove ;
from the beginning of) the line to load the php5_module module.
LoadModule php5_module libexec/apache2/libphp5.so
Start Apache HTTP with sudo apachectl start
(or restart
if it's already started and needs to be restarted to re-read the configuration file).
Make sure that /var/log/apache2/error_log
contains a line that tells you the php5_module is enabled - you should see PHP/5.3.15
(or similar).
[notice] Apache/2.2.22 (Unix) DAV/2 PHP/5.3.15 with Suhosin-Patch configured -- resuming normal operations
When MySQL is up and running (with ./bin/mysqld_safe
) there should be debug lines printed out to the console that tell you where you can find the log files. Note the hostname in the file name - localhost
in my case - that may be different for your configuration.
The file that comes after Logging to
is important. That's where MySQL logs its work.
130309 12:17:59 mysqld_safe Logging to '/Users/jacek/apps/mysql/data/localhost.err'.
130309 12:17:59 mysqld_safe Starting mysqld daemon with databases from /Users/jacek/apps/mysql/data
Open the localhost.err
file (again, yours might be named differently), i.e. tail -1 /Users/jacek/apps/mysql/data/localhost.err
to find out the socket file's name - it should be the last line.
$ tail -1 /Users/jacek/apps/mysql/data/localhost.err
Version: '5.5.27' socket: '/tmp/mysql.sock' port: 3306 MySQL Community Server (GPL)
Note the socket:
part - that's the socket file you should use in php.ini
.
There's another way (some say an easier way) to determine the location of the socket's file name by logging in to MySQL and running:
show variables like '%socket%';
Speaking of php.ini...
In /etc
directory there's /etc/php.ini.default file. Copy it to /etc/php.ini.
sudo cp /etc/php.ini.default /etc/php.ini
Open /etc/php.ini
and look for mysql.default_socket.
sudo vi /etc/php.ini
The default of mysql.default_socket
is /var/mysql/mysql.sock
. You should change it to the value you have noted earlier - it was /tmp/mysql.sock
in my case.
Replace the /etc/php.ini
file to reflect the socket file's name:
mysql.default_socket = /tmp/mysql.sock
mysqli.default_socket = /tmp/mysql.sock
Restart Apache HTTP.
sudo apachectl restart
Check the logs if there are no error related to PHP5. No errors means you're done and PHP5 with MySQL should work fine. Congrats!
It is called an interface. Many OO languages have this feature. You might want to read through the php explanation here: http://de2.php.net/interface
First of all: AddressOf
just gets the delegate to a function - you cannot specify anything else (i.e. capture any variables).
Now, you can start up a thread in two possible ways.
Action
in the constructor and just Start()
the thread.ParameterizedThreadStart
and forward one extra object argument to the method pointed to when calling .Start(parameter)
I consider the latter option an anachronism from pre-generic, pre-lambda times - which have ended at the latest with VB10.
You could use that crude method and create a list or structure which you pass to your threading code as this single object parameter, but since we now have closures, you can just create the thread on an anonymous Sub
that knows all necessary variables by itself (which is work performed for you by the compiler).
Soo ...

You can use jQuery to do that for you.

Using the Pathlib library's Path.rename instead of os.rename:

new_path = original_path.rename('b.kml')
Node.js does not run in a browser, therefore you will not have a document
object available. Actually, you will not even have a DOM tree at all. If you are a bit confused at this point, I encourage you to read more about it before going further.
There are a few methods you can choose from to do what you want.
Because you wrote about opening the file in the browser, why don't you use a framework that will serve the file directly as an HTTP service, instead of having a two-step process? This way, your code will be more dynamic and easily maintainable (not mentioning your HTML always up-to-date).
There are plenty frameworks out there for that :
The most basic way you could do what you want is this :
var http = require('http');
http.createServer(function (req, res) {
var html = buildHtml(req);
res.writeHead(200, {
'Content-Type': 'text/html',
'Content-Length': html.length,
'Expires': new Date().toUTCString()
});
res.end(html);
}).listen(8080);
function buildHtml(req) {
var header = '';
var body = '';
// concatenate header string
// concatenate body string
return '<!DOCTYPE html>'
+ '<html><head>' + header + '</head><body>' + body + '</body></html>';
};
And access this HTML with http://localhost:8080
from your browser.
(Edit: you could also serve them with a small HTTP server.)
If what you are trying to do is simply generating some HTML files, then go simple. To perform IO access on the file system, Node has an API for that, documented here.
var fs = require('fs');
var fileName = 'path/to/file';
var stream = fs.createWriteStream(fileName);
stream.once('open', function(fd) {
var html = buildHtml();
stream.end(html);
});
Note: The buildHtml
function is exactly the same as in Method 1.
stdout
This is the most basic Node.js implementation and requires the invoking application to handle the output itself. To output something in Node (ie. to stdout), the best way is to use console.log(message)
where message
is any string, or object, etc.
var html = buildHtml();
console.log(html);
Note: The buildHtml
function is exactly the same as in Method 1 (again)
If your script is called html-generator.js
(for example), in Linux/Unix based system, simply do
$ node html-generator.js > path/to/file
Because Node is a modular system, you can even put the buildHtml
function inside it's own module and simply write adapters to handle the HTML however you like. Something like
var htmlBuilder = require('path/to/html-builder-module');
var html = htmlBuilder(options);
...
You have to think "server-side" and not "client-side" when writing JavaScript for Node.js; you are not in a browser and/or limited to a sandbox, other than the V8 engine.
Extra reading, learn about npm. Hope this helps.
Though the solution posted earlier to change the menu item itself, like below, works when the menu is on a small device, it has a side effect when the menu is on full width and expanded, this can result in a horizontal scrollbar sliding over your menu items. The javascript solutions do not have this side-effect.
<li><a href="#one">One</a></li> to
<li><a data-toggle="collapse" data-target=".navbar-collapse" href="#one">One</a></li>

My fix for KOTLIN
I came across the same bug, which i fixed with:
val separator = DecimalFormatSymbols.getInstance().decimalSeparator
mEditText.keyListener = DigitsKeyListener.getInstance("0123456789$separator")
and this works quite fine. !BUT! on Samsung Keyboards, the separator is NOT shown, so you cannot type in decimal numbers.
so i had to fix this issue with checking, if Samsung Keyboard is used:
val x = Settings.Secure.getString(getContentResolver(), Settings.Secure.DEFAULT_INPUT_METHOD);
if (x.toLowerCase().contains("samsung")) {}
But then you still have the "." as decimal separator. Therefore you have to replace the dot with comma, if the separator is comma:
val separator: Char = DecimalFormatSymbols.getInstance().decimalSeparator
if (separator == ',') {
mEditText.addTextChangedListener(object : TextWatcher {
override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) = Unit
override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) = Unit
override fun afterTextChanged(s: Editable?) {
if (!s.isNullOrEmpty()) {
if (s.toString().contains(".")) {
val replaced = s.toString().replace('.', separator)
mEditText.setText(replaced)
mEditText.setSelection(replaced.length)
}
}
}
})
}
But then you have to check that nobody types more "," in the EditTextfield. This can be done with a Regex.
My whole solution:
val x = Settings.Secure.getString(getContentResolver(), Settings.Secure.DEFAULT_INPUT_METHOD);
if (x.toLowerCase().contains("samsung")) {
val Number_REGEX: Pattern = Pattern.compile("^([1-9])*([.,]{1}[0-9]{0,10})?$")
val separator: Char = DecimalFormatSymbols.getInstance().decimalSeparator
if (separator == ',') {
mEditText.addTextChangedListener(object : TextWatcher {
override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) = Unit
override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) = Unit
override fun afterTextChanged(s: Editable?) {
if (!s.isNullOrEmpty()) {
val matcherMail = Number_REGEX.matcher(s.toString())
if (!matcherMail.matches()) {
val length: Int = s.length
s.delete(length - 1, length);
} else {
if (s.toString().contains(".")) {
val replaced = s.toString().replace('.', separator)
mEditText.setText(replaced)
mEditText.setSelection(replaced.length)
}
}
}
}
})
}
} else {
val separator = DecimalFormatSymbols.getInstance().decimalSeparator
mEditText.keyListener = DigitsKeyListener.getInstance("0123456789$separator")
}
xml file:
<com.google.android.material.textfield.TextInputEditText
android:id="@+id/tEditText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Input"
android:inputType="numberDecimal"
android:imeOptions="actionDone"/>
If you want to use the number, make sure to get the right format:
val x = NumberFormat.getInstance().parse(mEditText.text.toString()).toDouble()
You're calling br.readLine()
a second time inside the loop.
Therefore, you end up reading two lines each time you go around.
My handmade solution:
In the layout:
<LinearLayout
android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/dots"
/>
And in the Activity
private final static int NUM_PAGES = 5;
private ViewPager mViewPager;
private List<ImageView> dots;
@Override
protected void onCreate(Bundle savedInstanceState) {
// ...
addDots();
}
public void addDots() {
dots = new ArrayList<>();
LinearLayout dotsLayout = (LinearLayout)findViewById(R.id.dots);
for(int i = 0; i < NUM_PAGES; i++) {
ImageView dot = new ImageView(this);
dot.setImageDrawable(getResources().getDrawable(R.drawable.pager_dot_not_selected));
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT
);
dotsLayout.addView(dot, params);
dots.add(dot);
}
mViewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
}
@Override
public void onPageSelected(int position) {
selectDot(position);
}
@Override
public void onPageScrollStateChanged(int state) {
}
});
}
public void selectDot(int idx) {
Resources res = getResources();
for(int i = 0; i < NUM_PAGES; i++) {
int drawableId = (i==idx)?(R.drawable.pager_dot_selected):(R.drawable.pager_dot_not_selected);
Drawable drawable = res.getDrawable(drawableId);
dots.get(i).setImageDrawable(drawable);
}
}
I made a Method to do this
string test = "Paul";
test = ReplaceAtIndex(0, 'M', test);
(...)
static string ReplaceAtIndex(int i, char value, string word)
{
char[] letters = word.ToCharArray();
letters[i] = value;
return string.Join("", letters);
}
I think you are getting confused about what the a:active
CSS selector does. This will only change the colour of your link when you click it (and only for the duration of the click i.e. how long your mouse button stays down). What you need to do is introduce a new class e.g. .selected
into your CSS and when you select a link, update the selected menu item with new class e.g.
<div class="menuBar">
<ul>
<li class="selected"><a href="index.php">HOME</a></li>
<li><a href="two.php">PORTFOLIO</a></li>
....
</ul>
</div>
// specific CSS for your menu
div.menuBar li.selected a { color: #FF0000; }
// more general CSS
li.selected a { color: #FF0000; }
You will need to update your template page to take in a selectedPage
parameter.
Update: After several attempts, it looks like this may have been fixed in latest Chrome builds (per Paul Irish's comment below). That would suggest we will see this fixed in stable Chrome June-July 2016. Let's see ...
This is a known bug with the official Chromecast JavaScript library. Instead of failing silently, it dumps these error messages in all non-Chrome browsers as well as Chrome browsers where the Chromecast extension isn't present.
The Chromecast team have indicated they won't fix this bug.
If you are a developer shipping with this library, you can't do anything about it according to Chromecast team. You can only inform users to ignore the errors. (I believe Chromecast team is not entirely correct as the library could, at the least, avoid requesting the extension scipt if the browser is not Chrome. And I suspect it could be possible to suppress the error even if it is Chrome, but haven't tried anything.)
If you are a user annoyed by these console messages, you can switch to Chrome if not using it already. Within Chrome, either:
Update [Nov 13, 2014]: The problem has now been acknowledged by Google. A member of the Chromecast team seems to suggest the issue will be bypassed by a change the team is currently working on.
Update 2 [Feb 17, 2015]: The team claim there's nothing they can do to remove the error logs as it's a standard Chrome network error and they are still working on a long-term fix. Public comments on the bug tracker were closed with that update.
Update 3 [Dec 4, 2015]: This has finally been fixed! In the end, Chrome team simply added some code to block out this specific error. Hopefully some combination of devtools and extensions API will be improved in the future to make it possible to fix this kind of problem without patching the browser. Chrome Canary already has the patch, so it should roll out to all users around mid-January. Additionally, the team has confirmed the issue no longer affects other browsers as the SDK was updated to only activate if it's in Chrome.
Update 4 (April 30): Nope, not yet anyway. Thankfully Google's developer relations team are more aware than certain other stakeholders how badly this has affected developer experience. More whitelist updates have recently been made to clobber these log messages. Current status at top of the post.
The HTML specification never specifies any content formats. That's not its job. There's plenty of standards organizations that are more qualified than the W3C to specify video formats.
That's what content negotiation is for.
<img>
element.<style>
element.<script>
element.<object>
and embed
elements.<audio>
element.Why should it specify one for the <video>
element?
Use the following command to increase the timeout period so that you could retype password for a while
git config --global credential.helper 'cache --timeout 3600'
I used it for Bitbucket and GitHub it works for both. The only thing you need to do is
3600
is in seconds. Increase it to whatever extent you want. I changed it to 259200
which is about 30 days. This way I re-enter my password for every 30 days or so.
If you need pure Java without any dependencies, you can use build in Nashorn API from Java 8. It is deprecated in Java 11.
This is working for me:
...
import javax.script.ScriptEngine;
import javax.script.ScriptEngineManager;
import javax.script.ScriptException;
...
public class JsonUtils {
public static Map parseJSON(String json) throws ScriptException {
ScriptEngineManager sem = new ScriptEngineManager();
ScriptEngine engine = sem.getEngineByName("javascript");
String script = "Java.asJSONCompatible(" + json + ")";
Object result = engine.eval(script);
return (Map) result;
}
}
Sample usage
JSON:
{
"data":[
{"id":1,"username":"bruce"},
{"id":2,"username":"clark"},
{"id":3,"username":"diana"}
]
}
Code:
...
import jdk.nashorn.internal.runtime.JSONListAdapter;
...
public static List<String> getUsernamesFromJson(Map json) {
List<String> result = new LinkedList<>();
JSONListAdapter data = (JSONListAdapter) json.get("data");
for(Object obj : data) {
Map map = (Map) obj;
result.add((String) map.get("username"));
}
return result;
}
I think i am understanding your question. This filters things that are in the column labels or the row labels. The last 2 sections of the code is what you want but im pasting everything so that you can see exactly how It runs start to finish with everything thats defined etc. I definitely took some of this code from other sites fyi.
Near the end of the code, the "WardClinic_Category" is a column of my data and in the column label of the pivot table. Same for the IVUDDCIndicator (its a column in my data but in the row label of the pivot table).
Hope this helps others...i found it very difficult to find code that did this the "proper way" rather than using code similar to the macro recorder.

Look into twitter cards.
The trick is not in the button but rather the page you are sharing. Twitter Cards pull the image from the meta tags similar to facebook
sharing.
Example:
<meta name="twitter:card" content="summary_large_image">

In Xcode 4 and possibly before, in the run script build phase there is an option "Show enviroment variables in build phase". If selected this will show then on a olive green background in the build log.
I just ran into this error and it took days to resolve. We were thrown for a loop by the red-herring error message mentioned in the initial question, plus the Windows Event Viewer error log indicated something similar:
Login failed for user '(domain\name-PC)$'. Reason: Could not find a login matching the name provided. [CLIENT: <local machine>]
Neither of these was true, the user had all the necessary permissions in SQL Server.
In our case, the solution was to switch the Application Pool Identity in IIS to NetworkService
.
You can try xml2js. It's a simple XML to JavaScript object converter. It gets your XML converted to a JS object so that you can access its content with ease.
Here are some other options:
I have used xml2js
and it has worked fine for me. The rest you might have to try out for yourself.
Try reducing the range of the for loop to range(len(a)-1)
:
a = [0,1,2,3]
b = []
for i in range(len(a)-1):
b.append(a[i]+a[i+1])
print(b)
This can also be written as a list comprehension:
b = [a[i] + a[i+1] for i in range(len(a)-1)]
print(b)
Another way to accomplish this would be using a linq statement. The recomended answer did not work for me in .NetCore2.0. I was able to figure it out however and below would also work if you are using newer technology.

var listofIDs = collection.ToList().Select(x => x.ToString());
List<Dinner> dinners = new List<Dinner>();
dinners = repository.GetDinners(listofIDs);
return View(dinners);
}
You may use this class to test two accessing threads and one mutating the shared instance of ConcurrentHashMap

In the nav go View => Layout => Columns:2
(alt+shift+2
) and open your file again in the other pane (i.e. click the other pane and use ctrl+p filename.py
)
It appears you can also reopen the file using the command File -> New View into File
which will open the current file in a new tab
An established connection was aborted by the software in your host machine
That is a boiler-plate error message, it comes out of Windows. The underlying error code is WSAECONNABORTED. Which really doesn't mean more than "connection was aborted". You have to be a bit careful about the "your host machine" part of the phrase. In the vast majority of Windows application programs, it is indeed the host that the desktop app is connected to that aborted the connection. Usually a server somewhere else.
The roles are reversed however when you implement your own server. Now you need to read the error message as "aborted by the application at the other end of the wire". Which is of course not uncommon when you implement a server, client programs that use your server are not unlikely to abort a connection for whatever reason. It can mean that a fire-wall or a proxy terminated the connection but that's not very likely since they typically would not allow the connection to be established in the first place.
You don't really know why a connection was aborted unless you have insight what is going on at the other end of the wire. That's of course hard to come by. If your server is reachable through the Internet then don't discount the possibility that you are being probed by a port scanner. Or your customers, looking for a game cheat.
Depends in how you are hiding your div, diplay=none
is different of visibility=hidden
and the opacity=0
Visibility then use ...style.visibility='visible'
Display then use ...style.display='block'
(or others depends how
you setup ur css, inline, inline-block, flex...)
Opacity then use ...style.opacity='1';
You can use array.slice(0,1) // First index is removed and array is returned.
The above code didn't work for me.
So I found a new solution that actually works!
app.use(function(req, res, next) {
res.status(404).send('Unable to find the requested resource!');
});
Or you can even render it to a 404 page.
app.use(function(req, res, next) {
res.status(404).render("404page");
});
Hope this helped you!
The solutions here didn't work for me as I'm styling react components.
What worked though for the sidebar was
.sidebar{
position: sticky;
top: 0;
}
Hope this helps someone.
Here the async version.
public static Task<BitmapSource> ToBitmapSourceAsync(this Bitmap bitmap)
{
return Task.Run(() =>
{
using (System.IO.MemoryStream memory = new System.IO.MemoryStream())
{
bitmap.Save(memory, ImageFormat.Png);
memory.Position = 0;
BitmapImage bitmapImage = new BitmapImage();
bitmapImage.BeginInit();
bitmapImage.StreamSource = memory;
bitmapImage.CacheOption = BitmapCacheOption.OnLoad;
bitmapImage.EndInit();
bitmapImage.Freeze();
return bitmapImage as BitmapSource;
}
});
}
You can write a query as follows:
IF OBJECT_ID('ProcedureName','P') IS NOT NULL
DROP PROC ProcedureName
GO
CREATE PROCEDURE [dbo].[ProcedureName]
...your query here....
To be more specific on the above syntax:
OBJECT_ID is a unique id number for an object within the database, this is used internally by SQL Server. Since we are passing ProcedureName followed by you object type P which tells the SQL Server that you should find the object called ProcedureName which is of type procedure i.e., P
This query will find the procedure and if it is available it will drop it and create new one.
For detailed information about OBJECT_ID and Object types please visit : SYS.Objects
Why do you use new Array();
for hash? You need to use new Object()
instead.
And i think you will get what you want.
If it's a percentage width, then yes, it is respected. As Martin pointed out, things break down when you get to fractional pixels, but if your percentage values yield integer pixel value (e.g. 50.5% of 200px in the example) you'll get sensible, expected behaviour.
Edit: I've updated the example to show what happens to fractional pixels (in Chrome the values are truncated, so 50, 50.5 and 50.6 all show the same width).
Shown below different ways to do that. Please, note that there are a lot of network types in ConnectivityManager class. Also, if API >= 21, you can check the network types in NetworkCapabilities class.
ConnectivityMonitor connectivityMonitor = ConnectivityMonitor.getInstance(this);
boolean isWiFiConnected = connectivityMonitor.isWifiConnection();
boolean isMobileConnected = connectivityMonitor.isConnected(ConnectivityManager.TYPE_MOBILE);
Log.e(TAG, "onCreate: isWiFiConnected " + isWiFiConnected);
Log.e(TAG, "onCreate: isMobileConnected " + isMobileConnected);
ConnectivityMonitor.Listener connectivityListener = new ConnectivityMonitor.Listener() {
@Override
public void onConnectivityChanged(boolean connected, @Nullable NetworkInfo networkInfo) {
Log.e(TAG, "onConnectivityChanged: connected " + connected);
Log.e(TAG, "onConnectivityChanged: networkInfo " + networkInfo);
if (networkInfo != null) {
boolean isWiFiConnected = networkInfo.getType() == NetworkCapabilities.TRANSPORT_WIFI;
boolean isMobileConnected = networkInfo.getType() == NetworkCapabilities.TRANSPORT_CELLULAR;
Log.e(TAG, "onConnectivityChanged: isWiFiConnected " + isWiFiConnected);
Log.e(TAG, "onConnectivityChanged: isMobileConnected " + isMobileConnected);
}
}
};
connectivityMonitor.addListener(connectivityListener);
Hi all I had the same issue that was being caused by a duplicate support version 4 file that I had included while trying to get parse integrated. Deleted the extra inclusion from the libs directory and it works fine now!
Just posting because the root cause for my case has not been described her.
In my case the problem was that "assets/js/fuelux/treeview/fuelux.min.js" was adding a constructor .datepicker(), so that was overriding the assets/js/datetime/bootstrap-datepicker.js
just moving the
to be just before the $('.date-picker') solved my problem.
This is how i implemented strtok, Not that great but after working 2 hr on it finally got it worked. It does support multiple delimiters.
#include "stdafx.h"
#include <iostream>
using namespace std;

for(int j = 0; ptr != '\0'; j++) {
for(int i=0 ; filter[i] != '\0' ; i++) {
if(ptr[j] == '\0') {

If you want to pass in an array of Doctrine entities, try something like this (Symfony 3.0+):
protected $entities;
protected $selectedEntities;
public function __construct($entities = null, $selectedEntities = null)
{
$this->entities = $entities;
$this->selectedEntities = $selectedEntities;
}
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('entities', 'entity', [
'class' => 'MyBundle:MyEntity',
'choices' => $this->entities,
'property' => 'id',
'multiple' => true,
'expanded' => true,
'data' => $this->selectedEntities,
]);
}
you have an unmatched jSon string, if you want to convert into a list, try this
{
"id": "MyID",
"values": [
{
"id": "100",
"diaplayName": "MyValue1",
},
{
"id": "200",
"diaplayName": "MyValue2",
}
]
}
dict = {'name' : 'Fred', 'age' : 100, 'employed' : True }
# Choose key to print (could be a user input)
x = 'name'
if x in dict.keys():
print(x)
Try a clear: left on #inner2. Because they are both being set to float it should cause a line return.
#inner1 {_x000D_
float:left; _x000D_
}_x000D_
_x000D_
#inner2{_x000D_
float:left; _x000D_
clear: left;_x000D_
}

Since no other answer has cited the Java language standard, I have decided to write an answer of my own:
In Java, local variables are not, by default, initialized with a certain value (unlike, for example, the field of classes). From the language specification one (§4.12.5) can read the following:
A local variable (§14.4, §14.14) must be explicitly given a value before it is used, by either initialization (§14.4) or assignment (§15.26), in a way that can be verified using the rules for definite assignment (§16 (Definite Assignment)).
Therefore, since the variables a
and b
are not initialized :
for (int l= 0; l<x.length; l++)
{
if (x[l] == 0)
a++ ;
else if (x[l] == 1)
b++ ;
}
the operations a++;
and b++;
could not produce any meaningful results, anyway. So it is logical for the compiler to notify you about it:
Rand.java:72: variable a might not have been initialized
a++ ;
^
Rand.java:74: variable b might not have been initialized
b++ ;
^
However, one needs to understand that the fact that a++;
and b++;
could not produce any meaningful results has nothing to do with the reason why the compiler displays an error. But rather because it is explicitly set on the Java language specification that
A local variable (§14.4, §14.14) must be explicitly given a value (...)
To showcase the aforementioned point, let us change a bit your code to:
public static Rand searchCount (int[] x)
{
if(x == null || x.length == 0)
return null;
int a ;
int b ;
...
for (int l= 0; l<x.length; l++)
{
if(l == 0)
a = l;
if(l == 1)
b = l;
}
...
}
So even though the code above can be formally proven to be valid (i.e., the variables a
and b
will be always assigned with the value 0
and 1
, respectively) it is not the compiler job to try to analyze your application's logic, and neither does the rules of local variable initialization rely on that. The compiler checks if the variables a
and b
are initialized according to the local variable initialization rules, and reacts accordingly (e.g., displaying a compilation error).
I suppose rgba()
would work here. After all, browser support for both box-shadow
and rgba()
is roughly the same.
/* 50% black box shadow */
box-shadow: 10px 10px 10px rgba(0, 0, 0, 0.5);
div {_x000D_
width: 200px;_x000D_
height: 50px;_x000D_
line-height: 50px;_x000D_
text-align: center;_x000D_
color: white;_x000D_
background-color: red;_x000D_
margin: 10px;_x000D_
}_x000D_
_x000D_
div.a {_x000D_
box-shadow: 10px 10px 10px #000;_x000D_
}_x000D_
_x000D_
div.b {_x000D_
box-shadow: 10px 10px 10px rgba(0, 0, 0, 0.5);_x000D_
}
_x000D_
<div class="a">100% black shadow</div>_x000D_
<div class="b">50% black shadow</div>
_x000D_
Thanks, Rippon! I have finally got this working too, after many struggles, and my solution is very close to what you suggested! The key was to make my own Job to extend QuartzJobBean, and to use the schedulerContextAsMap.
I did get away without specifying the applicationContextSchedulerContextKey property - it worked without it for me.
For the benefit of others, here is the final configuration that has worked for me:
<bean id="quartzScheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="configLocation" value="classpath:spring/quartz.properties"/>
<property name="jobFactory">
<bean class="org.springframework.scheduling.quartz.SpringBeanJobFactory" />
</property>
<property name="schedulerContextAsMap">
<map>
<entry key="mailService" value-ref="mailService" />
</map>
</property>
</bean>
<bean id="jobTriggerFactory"
class="org.springframework.beans.factory.config.ObjectFactoryCreatingFactoryBean">
<property name="targetBeanName">
<idref local="jobTrigger" />
</property>
</bean>
<bean id="jobTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerBean"
scope="prototype">
<property name="group" value="myJobs" />
<property name="description" value="myDescription" />
<property name="repeatCount" value="0" />
</bean>
<bean id="jobDetailFactory"
class="org.springframework.beans.factory.config.ObjectFactoryCreatingFactoryBean">
<property name="targetBeanName">
<idref local="jobDetail" />
</property>
</bean>
<bean id="jobDetail" class="org.springframework.scheduling.quartz.JobDetailBean"
scope="prototype">
<property name="jobClass" value="com.cambridgedata.notifications.EMailJob" />
<property name="volatility" value="false" />
<property name="durability" value="false" />
<property name="requestsRecovery" value="true" />
</bean>
<bean id="notificationScheduler" class="com.cambridgedata.notifications.NotificationScheduler">
<constructor-arg ref="quartzScheduler" />
<constructor-arg ref="jobDetailFactory" />
<constructor-arg ref="jobTriggerFactory" />
</bean>
Notice that the 'mailService" bean is my own service bean, managed by Spring. I was able to access it in my Job as following:
public void executeInternal(JobExecutionContext context)
throws JobExecutionException {
logger.info("EMailJob started ...");
....
SchedulerContext schedulerContext = null;
try {
schedulerContext = context.getScheduler().getContext();
} catch (SchedulerException e1) {
e1.printStackTrace();
}
MailService mailService = (MailService)schedulerContext.get("mailService");
....
And this configuration also allowed me to dynamically scheduler jobs, by using factories to get Triggers and JobDetails and setting required parameters on them programmatically:
public NotificationScheduler(final Scheduler scheduler,
final ObjectFactory<JobDetail> jobDetailFactory,
final ObjectFactory<SimpleTrigger> jobTriggerFactory) {
this.scheduler = scheduler;
this.jobDetailFactory = jobDetailFactory;
this.jobTriggerFactory = jobTriggerFactory;
...
// create a trigger
SimpleTrigger trigger = jobTriggerFactory.getObject();
trigger.setRepeatInterval(0L);
trigger.setStartTime(new Date());
// create job details
JobDetail emailJob = jobDetailFactory.getObject();
emailJob.setName("new name");
emailJob.setGroup("immediateEmailsGroup");
...
Thanks a lot again to everybody who helped,
Marina
This may help you find what you're looking for... Batch script loop
My answer is as follows:
@echo off
:start
set /a var+=1
if %var% EQU 100 goto end
:: Code you want to run goes here
goto start
:end
echo var has reached %var%.
pause
exit
The first set of commands under the start label loops until a variable, %var% reaches 100. Once this happens it will notify you and allow you to exit. This code can be adapted to your needs by changing the 100 to 17 and putting your code or using a call command followed by the batch file's path (Shift+Right Click on file and select "Copy as Path") where the comment is placed.
seq -w
will detect the max input width and normalize the width of the output.
for num in $(seq -w 01 05); do
...
done
At time of writing this didn't work on the newest versions of OSX, so you can either install macports and use its version of seq
, or you can set the format explicitly:
seq -f '%02g' 1 3
01
02
03
But given the ugliness of format specifications for such a simple problem, I prefer the solution Henk and Adrian gave, which just uses Bash. Apple can't screw this up since there's no generic "unix" version of Bash:
echo {01..05}
Or:
for number in {01..05}; do ...; done
Just create a button element with jQuery, and add the event handler when you create it :
var div = $('<div />', {'data-role' : 'fieldcontain'}),
btn = $('<input />', {
type : 'button',
value : 'Dynamic Button',
id : 'btn_a',
on : {
click: function() {
alert ( this.value );
}
}
});
div.append(btn).appendTo( $('#pg_menu_content').empty() );
bool IsPowerOfTwo(ulong x)
{
return x > 0 && (x & (x - 1)) == 0;
}
I wanted the simplest case, finally this is a result:
echo -n 'Tell me the length of this sentence.' | wc -m;
36
You can create variable like this:
x = 10
print(x)
Or this:
globals()['y'] = 100
print(y)
Lets create a new class:
class Foo(object):
def __init__(self):
self.name = 'John'
You can create class instance this way:
instance_name_1 = Foo()
Or this way:
globals()['instance_name_2'] = Foo()
Lets create a function:
def create_new_instance(class_name,instance_name):
globals()[instance_name] = class_name()
print('Class instance '{}' created!'.format(instance_name))
Call a function:
create_new_instance(Foo,'new_instance') #Class instance 'new_instance' created!
print(new_instance.name) #John
Also we can write generator function:
def create_instance(class_name,instance_name):
count = 0
while True:
name = instance_name + str(count)
globals()[name] = class_name()
count += 1
print('Class instance: {}'.format(name))
yield True
generator_instance = create_instance(Foo,'instance_')
for i in range(5):
next(generator_instance)
#out
#Class instance: instance_0
#Class instance: instance_1
#Class instance: instance_2
#Class instance: instance_3
#Class instance: instance_4
print(instance_0.name) #john
print(instance_1.name) #john
print(instance_2.name) #john
print(instance_3.name) #john
print(instance_4.name) #john
#print(instance_5.name) #error.. we only created 5 instances..
next(generator_instance) #Class instance: instance_5
print(instance_5.name) #John Now it works..
You appear to have a heredoc
containing a single SQL*Plus command, though it doesn't look right as noted in the comments. You can either pass a value in the heredoc
:
sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql BUILDING
exit;
EOF
or if BUILDING
is $2
in your script:
sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql $2
exit;
EOF
If your file.sql
had an exit
at the end then it would be even simpler as you wouldn't need the heredoc
:
sqlplus -S user/pass@localhost @/opt/D2RQ/file.sql $2
In your SQL you can then refer to the position parameters using substitution variables:
...
}',SEM_Models('&1'),NULL,
...
The &1
will be replaced with the first value passed to the SQL script, BUILDING
; because that is a string it still needs to be enclosed in quotes. You might want to set verify off
to stop if showing you the substitutions in the output.
You can pass multiple values, and refer to them sequentially just as you would positional parameters in a shell script - the first passed parameter is &1
, the second is &2
, etc. You can use substitution variables anywhere in the SQL script, so they can be used as column aliases with no problem - you just have to be careful adding an extra parameter that you either add it to the end of the list (which makes the numbering out of order in the script, potentially) or adjust everything to match:
sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count BUILDING
exit;
EOF
or:
sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count $2
exit;
EOF
If total_count
is being passed to your shell script then just use its positional parameter, $4
or whatever. And your SQL would then be:
SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
?s rdf:type :ProcessSpec .
?s ?p ?o
}',SEM_Models('&2'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));
If you pass a lot of values you may find it clearer to use the positional parameters to define named parameters, so any ordering issues are all dealt with at the start of the script, where they are easier to maintain:
define MY_ALIAS = &1
define MY_MODEL = &2
SELECT COUNT(*) as &MY_ALIAS
FROM TABLE(SEM_MATCH(
'{
?s rdf:type :ProcessSpec .
?s ?p ?o
}',SEM_Models('&MY_MODEL'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));
From your separate question, maybe you just wanted:
SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
?s rdf:type :ProcessSpec .
?s ?p ?o
}',SEM_Models('&1'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));
... so the alias will be the same value you're querying on (the value in $2
, or BUILDING
in the original part of the answer). You can refer to a substitution variable as many times as you want.
That might not be easy to use if you're running it multiple times, as it will appear as a header above the count value in each bit of output. Maybe this would be more parsable later:
select '&1' as QUERIED_VALUE, COUNT(*) as TOTAL_COUNT
If you set pages 0
and set heading off
, your repeated calls might appear in a neat list. You might also need to set tab off
and possibly use rpad('&1', 20)
or similar to make that column always the same width. Or get the results as CSV with:
select '&1' ||','|| COUNT(*)
Depends what you're using the results for...

For different types of arguments, there is 3-dots :
public void foo(Object... x) {
String myVar1 = x.length > 0 ? (String)x[0] : "Hello";
int myVar2 = x.length > 1 ? Integer.parseInt((String) x[1]) : 888;
}
Then call it
foo("Hii");
foo("Hii", 146);
for security, use like this:
if (!(x[0] instanceof String)) { throw new IllegalArgumentException("..."); }
The main drawback of this approach is that if optional parameters are of different types you lose static type checking. Please, see more variations .

Successfully ran freestyle step: Cloning the repo
On windows, nearly all AMPP (Apache,MySQL,PHP,PHPmyAdmin) packages don't include a mail server (but nearly all naked linuxes do have!). So, when using PHP under windows, you need to setup a mail server!
Imo the best and most simple tool ist this: http://smtp4dev.codeplex.com/
SMTP4Dev is a simple one-file mail server tool that does collect the mails it send (so it does not really sends mail, it just keeps them for development). Perfect tool.
If you want to also allow alphanumeric characters which don't belong to the ascii characters set, like for instance german umlaut's, you can consider using the following solution:
String value = "your value";
// this could be placed as a static final constant, so the compiling is only done once
Pattern pattern = Pattern.compile("[^\\w]", Pattern.UNICODE_CHARACTER_CLASS);
value = pattern.matcher(value).replaceAll("");
Please note that the usage of the UNICODE_CHARACTER_CLASS flag could have an impose on performance penalty (see javadoc of this flag)
Here is a solution to deal with files, which may be used more frequently...
int convert(char *infile, char *outfile) {
char *source = NULL;
FILE *fp = fopen(infile, "r");
long bufsize;
if (fp != NULL) {
/* Go to the end of the file. */
if (fseek(fp, 0L, SEEK_END) == 0) {
/* Get the size of the file. */
bufsize = ftell(fp);
if (bufsize == -1) { /* Error */ }
/* Allocate our buffer to that size. */
source = malloc(sizeof(char) * (bufsize + 1));
/* Go back to the start of the file. */
if (fseek(fp, 0L, SEEK_SET) != 0) { /* Error */ }
/* Read the entire file into memory. */
size_t newLen = fread(source, sizeof(char), bufsize, fp);
if ( ferror( fp ) != 0 ) {
fputs("Error reading file", stderr);
} else {
source[newLen++] = '\0'; /* Just to be safe. */
}
}
fclose(fp);
}
int sourceLen = bufsize - 1;
int destLen = sourceLen/2;
unsigned char* dest = malloc(destLen);
short i;
unsigned char highByte, lowByte;
for (i = 0; i < sourceLen; i += 2)
{
highByte = toupper(source[i]);
lowByte = toupper(source[i + 1]);
if (highByte > 0x39)
highByte -= 0x37;
else
highByte -= 0x30;
if (lowByte > 0x39)
lowByte -= 0x37;
else
lowByte -= 0x30;
dest[i / 2] = (highByte << 4) | lowByte;
}
FILE *fop = fopen(outfile, "w");
if (fop == NULL) return 1;
fwrite(dest, 1, destLen, fop);
fclose(fop);
free(source);
free(dest);
return 0;
}
You need to point to the directory instead. You must not specify the dockerfile.
docker build -t ubuntu-test:latest .
does work.
docker build -t ubuntu-test:latest ./Dockerfile
does not work.
URL url = new URL(yourUrl, "/api/v1/status.xml");
According to the javadocs this constructor just appends whatever resource to the end of your domain, so you would want to create 2 urls:
URL domain = new URL("http://example.com");
URL url = new URL(domain + "/files/resource.xml");

You should have look at http://en.wikipedia.org/wiki/Breadth-first_search first.
Below is a quick implementation, in which I used a list of list to represent the queue of paths.
# graph is in adjacent list representation
graph = {
'1': ['2', '3', '4'],
'2': ['5', '6'],
'5': ['9', '10'],
'4': ['7', '8'],
'7': ['11', '12']
}
def bfs(graph, start, end):
# maintain a queue of paths
queue = []
# push the first path into the queue
queue.append([start])
while queue:
# get the first path from the queue
path = queue.pop(0)
# get the last node from the path
node = path[-1]
# path found
if node == end:
return path
# enumerate all adjacent nodes, construct a new path and push it into the queue
for adjacent in graph.get(node, []):
new_path = list(path)
new_path.append(adjacent)
queue.append(new_path)
print bfs(graph, '1', '11')
Another approach would be maintaining a mapping from each node to its parent, and when inspecting the adjacent node, record its parent. When the search is done, simply backtrace according the parent mapping.
graph = {
'1': ['2', '3', '4'],
'2': ['5', '6'],
'5': ['9', '10'],
'4': ['7', '8'],
'7': ['11', '12']
}
def backtrace(parent, start, end):
path = [end]
while path[-1] != start:
path.append(parent[path[-1]])
path.reverse()
return path
def bfs(graph, start, end):
parent = {}
queue = []
queue.append(start)
while queue:
node = queue.pop(0)
if node == end:
return backtrace(parent, start, end)
for adjacent in graph.get(node, []):
if node not in queue :
parent[adjacent] = node # <<<<< record its parent
queue.append(adjacent)
print bfs(graph, '1', '11')
The above codes are based on the assumption that there's no cycles.
The usual way to do it is as outlined by Guffa, nested elements. It's a bit sad having to add extra markup to get the hooks you need for this, but in practice a wrapper div here or there isn't going to hurt anyone.
If you must do it without extra elements (eg. when you don't have control of the page markup), you can use box-sizing, which has pretty decent but not complete or simple browser support. Likely more fun than having to rely on scripting though.
declare @ids table(idx int identity(1,1), id int)
insert into @ids (id)
select 4 union
select 7 union
select 12 union
select 22 union
select 19
declare @i int
declare @cnt int
select @i = min(idx) - 1, @cnt = max(idx) from @ids
while @i < @cnt
begin
select @i = @i + 1
declare @id = select id from @ids where idx = @i
exec p_MyInnerProcedure @id
end
You can use Kotlin, the Super (cede of) Java for JVM, it has a nice way of interpolating strings like those of ES5, Ruby and Python.
class Client(val firstName: String, val lastName: String) {
val fullName = "$firstName $lastName"
}
You can use fgets
and limit the size of the read string.
char *fgets(char *str, int num, FILE *stream);
You can change the while
in your code to:
while (fgets(str, 100, file)) /* printf("%s", str) */;
i tried the last answer from Sandeep Kumar, and i found way more simple :
<option value="1" <c:if test="${item.key == 1}"> selected </c:if>>
Instead of removing NS you can try removing replicaSet
kubectl get rs --all-namespaces
Then delete the replicaSet
kubectl delete rs your_app_name
That file will allow all crawlers access
User-agent: *
Allow: /
This basically allows all user agents (the *) to all parts of the site (the /).
This is a good way to do it:
<?php
if (!(isset($_SERVER['HTTPS']) && ($_SERVER['HTTPS'] == 'on' ||
$_SERVER['HTTPS'] == 1) ||
isset($_SERVER['HTTP_X_FORWARDED_PROTO']) &&
$_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https'))
{
$redirect = 'https://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
header('HTTP/1.1 301 Moved Permanently');
header('Location: ' . $redirect);
exit();
}
?>
It is varchar

You can create a new dictionary by sorting the current dictionary by key as per your question.
This is your dictionary
d = {2:3, 1:89, 4:5, 3:0}
Create a new dictionary d1 by sorting this d using lambda function
d1 = dict(sorted(d.items(), key = lambda x:x[0]))
d1 should be {1: 89, 2: 3, 3: 0, 4: 5}, sorted based on keys in d.
You could write a Kotlin extension like this:
fun String.isValidEmail() =
isNotEmpty() && android.util.Patterns.EMAIL_ADDRESS.matcher(this).matches()
And then call it like this:
email.isValidEmail()

I was struggling to find a solution for arbitrary length byte sequences that would work under Python 2.x. Finally I wrote this one, it's a bit hacky because it performs a string conversion, but it works.
def signedbytes(data):
"""Convert a bytearray into an integer, considering the first bit as
sign. The data must be big-endian."""
negative = data[0] & 0x80 > 0
if negative:
inverted = bytearray(~d % 256 for d in data)
return -signedbytes(inverted) - 1
encoded = str(data).encode('hex')
return int(encoded, 16)
This function has two requirements:
The input data
needs to be a bytearray
. You may call the function like this:
s = 'y\xcc\xa6\xbb'
n = signedbytes(s)
The data needs to be big-endian. In case you have a little-endian value, you should reverse it first:
n = signedbytes(s[::-1])
Of course, this should be used only if arbitrary length is needed. Otherwise, stick with more standard ways (e.g. struct
).
If you want to remove the default value constraint, you can do:
ALTER TABLE <table> ALTER COLUMN <column> DROP DEFAULT;
When a module is loaded from a file in Python, __file__
is set to its path. You can then use that with other functions to find the directory that the file is located in.
Taking your examples one at a time:
A = os.path.join(os.path.dirname(__file__), '..')
# A is the parent directory of the directory where program resides.
B = os.path.dirname(os.path.realpath(__file__))
# B is the canonicalised (?) directory where the program resides.
C = os.path.abspath(os.path.dirname(__file__))
# C is the absolute path of the directory where the program resides.
You can see the various values returned from these here:
import os
print(__file__)
print(os.path.join(os.path.dirname(__file__), '..'))
print(os.path.dirname(os.path.realpath(__file__)))
print(os.path.abspath(os.path.dirname(__file__)))
and make sure you run it from different locations (such as ./text.py
, ~/python/text.py
and so forth) to see what difference that makes.
I just want to address some confusion first. __file__
is not a wildcard it is an attribute. Double underscore attributes and methods are considered to be "special" by convention and serve a special purpose.
http://docs.python.org/reference/datamodel.html shows many of the special methods and attributes, if not all of them.
In this case __file__
is an attribute of a module (a module object). In Python a .py
file is a module. So import amodule
will have an attribute of __file__
which means different things under difference circumstances.
Taken from the docs:
__file__
is the pathname of the file from which the module was loaded, if it was loaded from a file. The__file__
attribute is not present for C modules that are statically linked into the interpreter; for extension modules loaded dynamically from a shared library, it is the pathname of the shared library file.
In your case the module is accessing it's own __file__
attribute in the global namespace.
To see this in action try:
# file: test.py
print globals()
print __file__
And run:
python test.py
{'__builtins__': <module '__builtin__' (built-in)>, '__name__': '__main__', '__file__':
'test_print__file__.py', '__doc__': None, '__package__': None}
test_print__file__.py
With eval("my script here")
function.
nbconvert is not yet fully replaced by nbconvert2, you can still use it if you wish, otherwise we would have removed the executable. It's just a warning that we do not bugfix nbconvert1 anymore.
The following should work :
./nbconvert.py --format=pdf yourfile.ipynb
If you are on a IPython recent enough version, do not use print view, just use the the normal print dialog. Graph beeing cut in chrome is a known issue (Chrome does not respect some print css), and works much better with firefox, not all versions still.
As for nbconvert2, it still highly dev and docs need to be written.
Nbviewer use nbconvert2 so it's pretty decent with HTML.
List of current available profiles:
$ ls -l1 profile|cut -d. -f1
base_html
blogger_html
full_html
latex_base
latex_sphinx_base
latex_sphinx_howto
latex_sphinx_manual
markdown
python
reveal
rst
Give you the existing profiles.
(You can create your own, cf future doc, ./nbconvert2.py --help-all
should give you some option you can use in your profile.)
then
$ ./nbconvert2.py [profilename] --no-stdout --write=True <yourfile.ipynb>
And it should write your (tex) files as long as extracted figures in cwd. Yes I know this is not obvious, and it will probably change hence no doc...
The reason for that is that nbconvert2 will mainly be a python library where in pseudo code you can do :
MyConverter = NBConverter(config=config)
ipynb = read(ipynb_file)
converted_files = MyConverter.convert(ipynb)
for file in converted_files :
write(file)
Entry point will come later, once the API is stabilized.
I'll just point out that @jdfreder (github profile) is working on tex/pdf/sphinx export and is the expert to generate PDF from ipynb file at the time of this writing.
A simple solution I frequently use:
arr = ['remove me',3,4,2,45]
arr[1..-1]
=> [3,4,2,45]
Look at the DefaultTableModel for a simple model that you can use:
http://java.sun.com/javase/6/docs/api/javax/swing/table/DefaultTableModel.html
This extends the AbstractTableModel, but should be sufficient for basic purposes. You can always extend AbstractTableModel and create your own. Make sure you set it on the JTable as well.
http://java.sun.com/javase/6/docs/api/javax/swing/table/AbstractTableModel.html
Look at the basic Sun tutorial for more information on using the JTable with the table model:
http://java.sun.com/docs/books/tutorial/uiswing/components/table.html#data
queryForList returns a List of LinkedHashMap objects.
You need to cast it first like this:
List list = jdbcTemplate.queryForList(...); for (Object o : list) { Map m = (Map) o; ... }
To read multiple sheets from a workbook, use readxl package as follows:
library(readxl)
library(dplyr)
final_dataFrame <- bind_rows(path_to_workbook %>%
excel_sheets() %>%
set_names() %>%
map(read_excel, path = path_to_workbook))
Here, bind_rows (dplyr
) will put all data rows from all sheets
into one data frame, and path_to_workbook
is the location of your data: "dir/of/the/data/workbook".
For an unmanaged DLL file, you need to first check if it is a 16-bit DLL file (hopefully not).
Then check the IMAGE\_FILE_HEADER.Machine
field.
Someone else took the time to work this out already, so I will just repeat here:
To distinguish between a 32-bit and 64-bit PE file, you should check IMAGE_FILE_HEADER.Machine field. Based on the Microsoft PE and COFF specification below, I have listed out all the possible values for this field: http://download.microsoft.com/download/9/c/5/9c5b2167-8017-4bae-9fde-d599bac8184a/pecoff_v8.doc
IMAGE_FILE_MACHINE_UNKNOWN 0x0 The contents of this field are assumed to be applicable to any machine type
IMAGE_FILE_MACHINE_AM33 0x1d3 Matsushita AM33
IMAGE_FILE_MACHINE_AMD64 0x8664 x64
IMAGE_FILE_MACHINE_ARM 0x1c0 ARM little endian
IMAGE_FILE_MACHINE_EBC 0xebc EFI byte code
IMAGE_FILE_MACHINE_I386 0x14c Intel 386 or later processors and compatible processors
IMAGE_FILE_MACHINE_IA64 0x200 Intel Itanium processor family
IMAGE_FILE_MACHINE_M32R 0x9041 Mitsubishi M32R little endian
IMAGE_FILE_MACHINE_MIPS16 0x266 MIPS16
IMAGE_FILE_MACHINE_MIPSFPU 0x366 MIPS with FPU
IMAGE_FILE_MACHINE_MIPSFPU16 0x466 MIPS16 with FPU
IMAGE_FILE_MACHINE_POWERPC 0x1f0 Power PC little endian
IMAGE_FILE_MACHINE_POWERPCFP 0x1f1 Power PC with floating point support
IMAGE_FILE_MACHINE_R4000 0x166 MIPS little endian
IMAGE_FILE_MACHINE_SH3 0x1a2 Hitachi SH3
IMAGE_FILE_MACHINE_SH3DSP 0x1a3 Hitachi SH3 DSP
IMAGE_FILE_MACHINE_SH4 0x1a6 Hitachi SH4
IMAGE_FILE_MACHINE_SH5 0x1a8 Hitachi SH5
IMAGE_FILE_MACHINE_THUMB 0x1c2 Thumb
IMAGE_FILE_MACHINE_WCEMIPSV2 0x169 MIPS little-endian WCE v2
Yes, you may check IMAGE_FILE_MACHINE_AMD64|IMAGE_FILE_MACHINE_IA64 for 64bit and IMAGE_FILE_MACHINE_I386 for 32bit.
I've got this error working in ASP.net. When I run the application from visual studio it worked all fine, but when I published the project and tested it , I've got that error "Autocomplete is not a function" in chrom Inspect debugger. I found out that the deferences between two environments were caused by a definition in web.config. in compilation tag. if assign debug="false" then all bundel definitions are executed and compilation is done as a release. if debug = true" then compilation is for a debug stage that not include bundeling and minifyning js library. Therefore the deferences between environments.
<system.web>
<compilation debug="false" targetFramework="4.5.1"/>
<httpRuntime targetFramework="4.5.1"/>
</system.web>
In addition, examining those two environments I saw that for debug environment everywhere (_Layout.cshtml) @Scripts.Render("~/bundles/jquery") was in the code, where (under APP_Start) BundleConfig.cs
bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
"~/Static/js/lib/jquery-{version}.js",
"~/Static/js/lib/jquery-ui.js"));
it rended as:
<script src="/Static/js/lib/jquery-1.12.4.js"></script>
<script src="/Static/js/lib/jquery-ui.js"></script>
and the other environment (debug = false)
<script src="/bundles/jquery?v=YOLEkbKJYtNeDq0o56xjzXWKoYzrF5Vkqgyc9Cb0YgI1"></script>
In debug mode it works and the other one got the problem.
Aspecting the js lib I saw two files of jquery-ui:
jquery-ui.js
jquery-ui.min.js
it turns out that both of them come as default from the template of new mvc project. When jquery-ui.min.js was deleted from the library the problem resolved.
I belive that even though jquery-ui.js was defined in BundleConfig.cs, actually jquery-ui.min.js was taken.
By the way, jquery-ui.min.js didn't include autocomple function apposed to jquery-ui.js that included it.
cheers.

"key_b" => "val_b"
}
File.open("public/temp.json","w") do |f|
f.write(tempHash.to_json)
end
Your temp.json file now looks like:
{"key_a":"val_a","key_b":"val_b"}
Realizing the revision of the code I found the cause of why the reading method did not work for me. The problem was that one of the dependencies that my project used jersey 1.x. Update the version, adjust the client and it works.
I use the following maven dependency:
<dependency>
<groupId>org.glassfish.jersey.core</groupId>
<artifactId>jersey-client</artifactId>
<version>2.28</version>

Use the replace
function in js:
var emailAdd = $(this).text().replace(/ /g,'');
That will remove all the spaces
If you want to remove the leading and trailing whitespace only, use the jQuery $.trim method :
var emailAdd = $.trim($(this).text());
A char value in C is implicitly convertible to an int. e.g, char c; ... printf("%d", c)
prints the decimal ASCII value of c
, and int i = c;
puts the ASCII integer value of c
in i
. You can also explicitly convert it with (int)c
. If you mean something else, such as how to convert an ASCII digit to an int, that would be c - '0'
, which implicitly converts c
to an int and then subtracts the ASCII value of '0'
, namely 48 (in C, character constants such as '0'
are of type int, not char, for historical reasons).

I just wanted to comment (I have not enough reps) on xenadu's implementation, because CChar
in OS X is Int8
, and Swift does not like at all when you add to the array when getchar()
returns parts of UTF-8, or anything else above 7 bit.
I am using an array of UInt8
instead, and it works great and String.fromCString
converts the UInt8
into UTF-8 just fine.
However this is how I done it
func readln() -> (str: String?, hadError: Bool) {
var cstr: [UInt8] = []
var c: Int32 = 0
while c != EOF {
c = getchar()
if (c == 10 || c == 13) || c > 255 { break }
cstr.append(UInt8(c))
}
cstr.append(0)
return String.fromCStringRepairingIllFormedUTF8(UnsafePointer<CChar>(cstr))
}
while true {
if let mystring = readln().str {
println(" > \(mystring)")
}
}
Try using:
if(NewType* v = dynamic_cast<NewType*>(old)) {
// old was safely casted to NewType
v->doSomething();
}
This requires your compiler to have rtti support enabled.
EDIT: I've had some good comments on this answer!
Every time you need to use a dynamic_cast (or instanceof) you'd better ask yourself whether it's a necessary thing. It's generally a sign of poor design.
Typical workarounds is putting the special behaviour for the class you are checking for into a virtual function on the base class or perhaps introducing something like a visitor where you can introduce specific behaviour for subclasses without changing the interface (except for adding the visitor acceptance interface of course).
As pointed out dynamic_cast doesn't come for free. A simple and consistently performing hack that handles most (but not all cases) is basically adding an enum representing all the possible types your class can have and check whether you got the right one.
if(old->getType() == BOX) {
Box* box = static_cast<Box*>(old);
// Do something box specific
}
This is not good oo design, but it can be a workaround and its cost is more or less only a virtual function call. It also works regardless of RTTI is enabled or not.
Note that this approach doesn't support multiple levels of inheritance so if you're not careful you might end with code looking like this:
// Here we have a SpecialBox class that inherits Box, since it has its own type
// we must check for both BOX or SPECIAL_BOX
if(old->getType() == BOX || old->getType() == SPECIAL_BOX) {
Box* box = static_cast<Box*>(old);
// Do something box specific
}
You may call U.difference(lists)
method in underscore-java library. I am the maintainer of the project. Live example
import com.github.underscore.U;
import java.util.Arrays;
import java.util.List;
public class Main {
public static void main(String[] args) {
List<Integer> list1 = Arrays.asList(1, 2, 3);
List<Integer> list2 = Arrays.asList(1, 2);
List<Integer> list3 = U.difference(list1, list2);
System.out.println(list3);
// [3]
}
}
Python has a min()
built-in function:
>>> darr = [1, 3.14159, 1e100, -2.71828]
>>> min(darr)
-2.71828
