Just iterate over the elements. Like this:
for (int i = numElements - 1; i >= 0; i--)
cout << array[i];
Note: As Maxim Egorushkin pointed out, this could overflow. See his comment below for a better solution.
You are not creating a separate dictionary for each iframe, you just keep modifying the same dictionary over and over, and you keep adding additional references to that dictionary in your list.
Remember, when you do something like content.append(info)
, you aren't making a copy of the data, you are simply appending a reference to the data.
You need to create a new dictionary for each iframe.
for iframe in soup.find_all('iframe'):
info = {}
...
Even better, you don't need to create an empty dictionary first. Just create it all at once:
for iframe in soup.find_all('iframe'):
info = {
"src": iframe.get('src'),
"height": iframe.get('height'),
"width": iframe.get('width'),
}
content.append(info)
There are other ways to accomplish this, such as iterating over a list of attributes, or using list or dictionary comprehensions, but it's hard to improve upon the clarity of the above code.
range()
can only work with integers, but dividing with the /
operator always results in a float value:
>>> 450 / 10
45.0
>>> range(450 / 10)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'float' object cannot be interpreted as an integer
Make the value an integer again:
for i in range(int(c / 10)):
or use the //
floor division operator:
for i in range(c // 10):
With the help of user=User.query.filter_by(username=form.username.data).first()
statement you will get the specified user in user
variable.
Now you can change the value of the new object variable like user.no_of_logins += 1
and save the changes with the session
's commit method.
You can use this but there remains a security issue
<script type="text/javascript">
function fnc1()
{
var a=window.location.href;
username="p";
password=1234;
window.open(a+'?username='+username+'&password='+password,"");
}
</script>
<input type="button" onclick="fnc1()" />
<input type="text" id="atext" />
You should check the EOF after reading from file.
fscanf_s // read from file
while(condition) // check EOF
{
fscanf_s // read from file
}
In SQL Server 2008 and newer you can cast the DateTime
to a Date
, which removes the time element.
WHERE Orders.OrderStatus = 'Shipped'
AND Orders.ShipDate >= (cast(GETDATE()-6 as date))
In SQL Server 2005 and below you can use:
WHERE Orders.OrderStatus = 'Shipped'
AND Orders.ShipDate >= DateAdd(Day, Datediff(Day,0, GetDate() -6), 0)
You can also use awk
for these purposes, since it allows you to perform more complex checks in a clearer way:
Lines not containing foo
:
awk '!/foo/'
Lines containing neither foo
nor bar
:
awk '!/foo/ && !/bar/'
Lines containing neither foo
nor bar
which contain either foo2
or bar2
:
awk '!/foo/ && !/bar/ && (/foo2/ || /bar2/)'
And so on.

It reads the file character by character, and reads 1 row at a time to a vector (of strings), therefore suitable for very large files.
Usage is
Iterate until an empty row is returned (end of file). A row is a vector where each entry is a CSV column.
read_csv_t csv;
csv.open("../test.csv");
std::vector<std::string> row;
while (true)

A simple representation written by 'Robert Sedgwick' and 'Kevin Wayne' is available at http://algs4.cs.princeton.edu/41graph/Graph.java.html
Explanation copied from the above page.
The Graph class represents an undirected graph of vertices named 0 through V - 1.
It supports the following two primary operations: add an edge to the graph, iterate over all of the vertices adjacent to a vertex. It also provides methods for returning the number of vertices V and the number of edges E. Parallel edges and self-loops are permitted. By convention, a self-loop v-v appears in the adjacency list of v twice and contributes two to the degree of v.
This implementation uses an adjacency-lists representation, which is a vertex-indexed array of Bag objects. All operations take constant time (in the worst case) except iterating over the vertices adjacent to a given vertex, which takes time proportional to the number of such vertices.
You can either do 1 of the following:
Change:
SET @UserId
= 0 to SELECT @UserId
This will return the value in the same way your 2nd part of the IF statement is.
Or, seeing as @UserId is set as an Output, change:
SELECT SCOPE_IDENTITY()
to SET @UserId = SCOPE_IDENTITY()
It depends on how you want to access the data afterwards. If you want the value to be in your result set, use SELECT
. If you want to access the new value of the @UserId parameter afterwards, then use SET @UserId
Seeing as you're accepting the 2nd condition as correct, the query you could write (without having to change anything outside of this query) is:
@EmailAddress varchar(200),
@NickName varchar(100),
@Password varchar(150),
@Sex varchar(50),
@Age int,
@EmailUpdates int,
@UserId int OUTPUT
IF
(SELECT COUNT(UserId) FROM RegUsers WHERE EmailAddress = @EmailAddress) > 0
BEGIN
SELECT 0
END
ELSE
BEGIN
INSERT INTO RegUsers (EmailAddress,NickName,PassWord,Sex,Age,EmailUpdates) VALUES (@EmailAddress,@NickName,@Password,@Sex,@Age,@EmailUpdates)
SELECT SCOPE_IDENTITY()
END
END
If you're using Python, you can define your environment variables in a .env
file and load them from within a Jupyter notebook using python-dotenv.
Install python-dotenv:
pip install python-dotenv
Load the .env
file in a Jupyter notebook:
%load_ext dotenv
%dotenv
Flash still has the ASO file, which is the compiled byte code for your classes. On Windows, you can see the ASO files here:
C:\Documents and Settings\username\Local Settings\Application Data\Adobe\Flash CS4\en\Configuration\Classes\aso
On a Mac, the directory structure is similar in /Users/username/Library/Application Support/
You can remove those files by hand, or in Flash you can select Control->Delete ASO files
to remove them.
@Jason-V, it really help, thanks. then, i found this examples and composed to own snippet.

I got this message while trying to commit a fragment using attach to root to true instead of false, like so:
return inflater.inflate(R.layout.fragment_profile, container, true)
After doing:
return inflater.inflate(R.layout.fragment_profile, container, false)
It worked.
Use this code between two words:
& vbCrLf &
Using this, the next word displays on the next line.
The above solution is good in some scenarios but there is another scenario where this happens when you are unit testing and you try to "Debug Selected Tests" from the Test Explorer when you solution is not set to Debug.
In this case you need to change your solution from Release or whatever it is set to to Debug in this case. If this is the problem then changing "ContextSwitchDeadlock" won't really help you.
I missed this myself because the error message was so nasty I didn't check the obvious thing which was the Debug setting!
this is the simple query .. if u want the second minimum then just change the max to min and change the less than(<) sign to grater than(>).
select max(column_name) from table_name where column_name<(select max(column_name) from table_name)
Patching as well Ralph Bolton's answer. Moving to a class and moving tulp of tulp (intervals) to dictionary. Adding an optional rounded function depending of granularity (enable by default). Ready to translation using gettext (default is disable). This is intend to be load from an module. This is for python3 (tested 3.6 - 3.8)

I have a french translation ready. But it's fast to do the translation ... just few words. Hope this could help as the other answer help me a lot.
JavaScript has a Number
type which is a 64 bit floating point number*.
If you're looking to convert a string to a number, use
parseInt
or parseFloat
. If using parseInt
, I'd recommend always passing the radix too.+
operator e.g. +"123456"
Number
constructor e.g. var n = Number("12343")
*there are situations where the number will internally be held as an integer.
Functionally, you use public/private key encryption to make certain only the receiver can read your message. The message is encrypted using the public key of the receiver and decrypted using the private key of the receiver.
Signing you can use to let the receiver know you created the message and it has not changed during transfer. Message signing is done using your own private key. The receiver can use your public key to check the message has not been tampered.
As for the algorithm used: that involves a one-way function see for example wikipedia. One of the first of such algorithms use large prime-numbers but more one-way functions have been invented since.
Search for 'Bob', 'Alice' and 'Mallory' to find introduction articles on the internet.
The problem appears to be that you are reinitializing the list to an empty list in each iteration:
while choice != 0:
...
a = []
a.append(s)
Try moving the initialization above the loop so that it is executed only once.
a = []
while choice != 0:
...
a.append(s)
Other easyway to do it on mac is :go to Command Palette[ Shift ?+ Command (?)+P] and type :Shell Command: Install 'code' command in PATH
once installed: Shell command 'code' successfully installed in PATH.
Then you can use code from the terminal as well.
Okay this is an example for the new embed code for youtube videos.
<iframe title="YouTube video player" class="youtube-player" type="text/html" width="560" height="345" src="http://www.youtube.com/embed/8v_4O44sfjM" frameborder="0" allowFullScreen></iframe>
if you want to autoplay it, at the src="http://www.youtube.com/embed/8v_4O44sfjM"
add the ?autoplay=1
parameter
So the code will look like this:
<iframe title="YouTube video player" class="youtube-player" type="text/html" width="560" height="345" src="http://www.youtube.com/embed/8v_4O44sfjM?autoplay=1" frameborder="0" allowFullScreen></iframe>

I was wondering what the parseInt() is for there? I've simplified it to this with no problems...
$("input[data-val-length-max]").each(function (index, element) {
element.setAttribute("maxlength", element.getAttribute("data-val-length-max"))
});
I would have commented on Nicks answer but don't have enough rep yet.
$(document).ready(function() {
$('#chkdwn2').click(function() {
if ($('#chkdwn2').prop('checked')) {
$('#dropdown').prop('disabled', true);
} else {
$('#dropdown').prop('disabled', false);
}
});
});
making use of .prop
in the if
statement.
Suppose you want to recover a file called MyFile
, but are uncertain of its path (or its extension, for that matter):
Preliminary: Avoid confusion by stepping to the git root
A nontrivial project may have multiple directories with similar or identical filenames.
> cd <project-root>
Find the full path
git log --diff-filter=D --summary | grep delete | grep MyFile
delete mode 100644 full/path/to/MyFile.js
full/path/to/MyFile.js
is the path & file you're seeking.
Determine all the commits that affected that file
git log --oneline --follow -- full/path/to/MyFile.js
bd8374c Some helpful commit message
ba8d20e Another prior commit message affecting that file
cfea812 The first message for a commit in which that file appeared.
Checkout the file
If you choose the first-listed commit (the last chronologically, here bd8374c), the file will not be found, since it was deleted in that commit.
> git checkout bd8374c -- full/path/to/MyFile.js
`error: pathspec 'full/path/to/MyFile.js' did not match any file(s) known to git.`
Just select the preceding (append a caret) commit:
> git checkout bd8374c^ -- full/path/to/MyFile.js
onLoadImage Full load
private void onLoadImage(final String imagePath) {
ImageSize targetSize = new ImageSize(imageView.getWidth(), imageView.getHeight()); // result Bitmap will be fit to this size
//ImageLoader imageLoader = ImageLoader.getInstance(); // Get singleto
com.nostra13.universalimageloader.core.ImageLoader imageLoader = com.nostra13.universalimageloader.core.ImageLoader.getInstance();
imageLoader.init(ImageLoaderConfiguration.createDefault(getContext()));
imageLoader.loadImage(imagePath, targetSize, new SimpleImageLoadingListener() {
@Override
public void onLoadingStarted(final String imageUri, View view) {
super.onLoadingStarted(imageUri, view);
progress2.setVisibility(View.VISIBLE);
new Handler().post(new Runnable() {
public void run() {
progress2.setColorSchemeResources(android.R.color.holo_green_light, android.R.color.holo_orange_light, android.R.color.holo_red_light);
// Picasso.with(getContext()).load(imagePath).into(imageView);
// Picasso.with(getContext()).load(imagePath) .memoryPolicy(MemoryPolicy.NO_CACHE, MemoryPolicy.NO_STORE).into(imageView);
Glide.with(getContext())
.load(imagePath)
.asBitmap()
.into(imageView);
}
});
}
@Override
public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) {
if (view == null) {
progress2.setVisibility(View.INVISIBLE);
}
// else {
Log.e("onLoadImage", "onLoadingComplete");
// progress2.setVisibility(View.INVISIBLE);
// }
// setLoagingCompileImage();
}
@Override
public void onLoadingFailed(String imageUri, View view, FailReason failReason) {
super.onLoadingFailed(imageUri, view, failReason);
if (view == null) {
progress2.setVisibility(View.INVISIBLE);
}
Log.e("onLoadingFailed", imageUri);
Log.e("onLoadingFailed", failReason.toString());
}
@Override
public void onLoadingCancelled(String imageUri, View view) {
super.onLoadingCancelled(imageUri, view);
if (view == null) {
progress2.setVisibility(View.INVISIBLE);
}
Log.e("onLoadImage", "onLoadingCancelled");

import sys

Change ignore to default when working on the file or adding new functionality to re-enable warnings.
To avoid syntax errors, be sure to always put BEGIN
and END
after an IF
clause, eg:
IF (@A!= @SA)
BEGIN
--do stuff
END
IF (@C!= @SC)
BEGIN
--do stuff
END
... and so on. This should work as expected. Imagine BEGIN
and END
keyword as the opening and closing bracket, respectively.
Using split()
Snippet :
var data =$('#date').text();_x000D_
var arr = data.split('/');_x000D_
$("#date").html("<span>"+arr[0] + "</span></br>" + arr[1]+"/"+arr[2]);
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="date">23/05/2013</div>
_x000D_
When you split this string --->
23/05/2013
on /
var myString = "23/05/2013";
var arr = myString.split('/');
you'll get an array of size 3
arr[0] --> 23
arr[1] --> 05
arr[2] --> 2013
You can read the lines and replace all special characters safely this way.
Keep in mind that if you use \\W
you will not replace underscores.
Scanner scan = new Scanner(System.in);
while(scan.hasNextLine()){
System.out.println(scan.nextLine().replaceAll("[^a-zA-Z0-9]", ""));
}
Alternately, if you are using a Macro Enabled workbook:
Add any control at all from the Developer -> Insert (Probably a button)
When it asks what Macro to assign, choose New. For the code for the generated module enter something like:
Thisworkbook.Sheets("Sheet Name").Activate
However, if you are not using Macros in your work book. Ooo's approach is definitely surperior as hyperlinks will work with no need to trust the document.
I made an adaptation of the Microsoft way, where I override the ListView
control to make a SortableListView
:
public partial class SortableListView : ListView
{
private GridViewColumnHeader lastHeaderClicked = null;
private ListSortDirection lastDirection = ListSortDirection.Ascending;
public void GridViewColumnHeaderClicked(GridViewColumnHeader clickedHeader)
{
ListSortDirection direction;
if (clickedHeader != null)
{
if (clickedHeader.Role != GridViewColumnHeaderRole.Padding)
{
if (clickedHeader != lastHeaderClicked)
{
direction = ListSortDirection.Ascending;
}
else
{
if (lastDirection == ListSortDirection.Ascending)
{
direction = ListSortDirection.Descending;
}
else
{
direction = ListSortDirection.Ascending;
}
}
string sortString = ((Binding)clickedHeader.Column.DisplayMemberBinding).Path.Path;
Sort(sortString, direction);
lastHeaderClicked = clickedHeader;
lastDirection = direction;
}
}
}
private void Sort(string sortBy, ListSortDirection direction)
{
ICollectionView dataView = CollectionViewSource.GetDefaultView(this.ItemsSource != null ? this.ItemsSource : this.Items);
dataView.SortDescriptions.Clear();
SortDescription sD = new SortDescription(sortBy, direction);
dataView.SortDescriptions.Add(sD);
dataView.Refresh();
}
}
The line ((Binding)clickedHeader.Column.DisplayMemberBinding).Path.Path
bit handles the cases where your column names are not the same as their binding paths, which the Microsoft method does not do.
I wanted to intercept the GridViewColumnHeader.Click
event so that I wouldn't have to think about it anymore, but I couldn't find a way to to do. As a result I add the following in XAML for every SortableListView
:
GridViewColumnHeader.Click="SortableListViewColumnHeaderClicked"
And then on any Window
that contains any number of SortableListView
s, just add the following code:
private void SortableListViewColumnHeaderClicked(object sender, RoutedEventArgs e)
{
((Controls.SortableListView)sender).GridViewColumnHeaderClicked(e.OriginalSource as GridViewColumnHeader);
}
Where Controls
is just the XAML ID for the namespace in which you made the SortableListView
control.
So, this does prevent code duplication on the sorting side, you just need to remember to handle the event as above.
As other answers have mentioned, the following calls will compute the hash:
MD5Context md5;
MD5Init(&md5);
MD5Update(&md5, data, datalen);
MD5Final(digest, &md5);
The purpose of splitting it up into that many functions is to let you stream large datasets.
For example, if you're hashing a 10GB file and it doesn't fit into ram, here's how you would go about doing it. You would read the file in smaller chunks and call MD5Update
on them.
MD5Context md5;
MD5Init(&md5);
fread(/* Read a block into data. */)
MD5Update(&md5, data, datalen);
fread(/* Read the next block into data. */)
MD5Update(&md5, data, datalen);
fread(/* Read the next block into data. */)
MD5Update(&md5, data, datalen);
...
// Now finish to get the final hash value.
MD5Final(digest, &md5);
$(":checkbox:checked").each(function () {
this.click();
});
to unchecked checked box, turn your logic around to do opposite
If you want to just compare dates,
yourdatetime.date() < datetime.today().date()
Or, obviously,
yourdatetime.date() == datetime.today().date()
If you want to check that they're the same date.
The documentation is usually helpful. It is also usually the first google result for python thing_i_have_a_question_about
. Unless your question is about a function/module named "snake".
Basically, the datetime
module has three types for storing a point in time:
date
for year, month, day of monthtime
for hours, minutes, seconds, microseconds, time zone infodatetime
combines date and time. It has the methods date()
and time()
to get the corresponding date
and time
objects, and there's a handy combine
function to combine date
and time
into a datetime
.In this instance, your div
elements have been changed from block
level elements to inline
elements. A typical characteristic of inline
elements is that they respect the whitespace in the markup. This explains why a gap of space is generated between the elements. (example)
There are a few solutions that can be used to solve this.
Example 1 - Comment the whitespace out: (example)
<div>text</div><!--
--><div>text</div><!--
--><div>text</div><!--
--><div>text</div><!--
--><div>text</div>
Example 2 - Remove the line breaks: (example)
<div>text</div><div>text</div><div>text</div><div>text</div><div>text</div>
Example 3 - Close part of the tag on the next line (example)
<div>text</div
><div>text</div
><div>text</div
><div>text</div
><div>text</div>
Example 4 - Close the entire tag on the next line: (example)
<div>text
</div><div>text
</div><div>text
</div><div>text
</div><div>text
</div>
font-size
Since the whitespace between the inline
elements is determined by the font-size
, you could simply reset the font-size
to 0
, and thus remove the space between the elements.
Just set font-size: 0
on the parent elements, and then declare a new font-size
for the children elements. This works, as demonstrated here (example)
#parent {
font-size: 0;
}
#child {
font-size: 16px;
}
This method works pretty well, as it doesn't require a change in the markup; however, it doesn't work if the child element's font-size
is declared using em
units. I would therefore recommend removing the whitespace from the markup, or alternatively floating the elements and thus avoiding the space generated by inline
elements.
display: flex
In some cases, you can also set the display
of the parent element to flex
. (example)
This effectively removes the spaces between the elements in supported browsers. Don't forget to add appropriate vendor prefixes for additional support.
.parent {
display: flex;
}
.parent > div {
display: inline-block;
padding: 1em;
border: 2px solid #f00;
}
.parent {_x000D_
display: flex;_x000D_
}_x000D_
.parent > div {_x000D_
display: inline-block;_x000D_
padding: 1em;_x000D_
border: 2px solid #f00;_x000D_
}
_x000D_
<div class="parent">_x000D_
<div>text</div>_x000D_
<div>text</div>_x000D_
<div>text</div>_x000D_
<div>text</div>_x000D_
<div>text</div>_x000D_
</div>
_x000D_
It is incredibly unreliable to use negative margins to remove the space between inline
elements. Please don't use negative margins if there are other, more optimal, solutions.
Give them a trivial pom with these jars listed as dependencies and instructions to run:
mvn dependency:go-offline
This will pull the dependencies to the local repo.
A more direct solution is dependency:get, but it's a lot of arguments to type:
mvn dependency:get -DrepoUrl=something -Dartifact=group:artifact:version
Samuel Yang answer tripped me up, here is my 3 cents worth.
Adrian Hum is right, make sure you put quotes around your filename. Not because it can't handle spaces as zourtney pointed out, but because it will recognize the commas (and possibly other characters) in filenames as separate arguments. So it should look as Adrian Hum suggested.
string argument = "/select, \"" + filePath +"\"";
You have to be very careful about the method names. In this case, the method name is just "lowercaseString
", not "lowercaseString:
" (note the absence of the colon). That's why you're getting NO
returned, because NSString
objects respond to the lowercaseString
message but not the lowercaseString:
message.
How do you know when to add a colon? You add a colon to the message name if you would add a colon when calling it, which happens if it takes one argument. If it takes zero arguments (as is the case with lowercaseString
), then there is no colon. If it takes more than one argument, you have to add the extra argument names along with their colons, as in compare:options:range:locale:
.
You can also look at the documentation and note the presence or absence of a trailing colon.
define a String variable using the JSP tags
<%!
String test = new String();
%>
then refer to that variable in your loop as
<c:forEach items="${myParams.items}" var="currentItem" varStatus="stat">
test+= whaterver_value
</c:forEach>
Are you using JavaScript or jQuery besides the html? If you are, you can do something like:
HTML:
<select id='some_selector'></select>?
jQuery:
var select = '';
for (i=1;i<=100;i++){
select += '<option val=' + i + '>' + i + '</option>';
}
$('#some_selector').html(select);
As you can see here.
Another option for compatible browsers instead of select, you can use is HTML5's input type=number
:
<input type="number" min="1" max="100" value="1">
commit
schedules the transaction, i.e. it doesn't happen straightaway but is scheduled as work on the main thread the next time the main thread is ready.
I'd suggest adding an
onAttach(Activity activity)
method to your Fragment
and putting a break point on it and seeing when it is called relative to your call to asd()
. You'll see that it is called after the method where you make the call to asd()
exits. The onAttach
call is where the Fragment
is attached to its activity and from this point getActivity()
will return non-null (nb there is also an onDetach()
call).
If you already has a repository and just changed the way you do authentication to MFA, u can change your remote origin
HTTP URI to use your new api token as follows:
git remote set-url origin https://oauth2:TOKEN@ANY_GIT_PROVIDER_DOMAIN/YOUR_PROJECT/YOUR_REPO.git
And you wont need to re-clone the repository at all.
@GetMapping
is a composed annotation that acts as a shortcut for @RequestMapping(method = RequestMethod.GET)
.
@GetMapping
is the newer annotaion.
It supports consumes
Consume options are :
consumes = "text/plain"
consumes = {"text/plain", "application/*"}
For Further details see: GetMapping Annotation
or read: request mapping variants
RequestMapping supports consumes as well
GetMapping we can apply only on method level and RequestMapping annotation we can apply on class level and as well as on method level
In addition to SAX and DOM there is STaX parsing available using XMLStreamReader which is an xml pull parser.
This link explains in good manner :
http://www.stevideter.com/2008/12/07/saveorupdate-versus-merge-in-hibernate/
We all have those problems that we encounter just infrequently enough that when we see them again, we know we’ve solved this, but can’t remember how.
The NonUniqueObjectException thrown when using Session.saveOrUpdate() in Hibernate is one of mine. I’ll be adding new functionality to a complex application. All my unit tests work fine. Then in testing the UI, trying to save an object, I start getting an exception with the message “a different object with the same identifier value was already associated with the session.” Here’s some example code from Java Persistence with Hibernate.
Session session = sessionFactory1.openSession();
Transaction tx = session.beginTransaction();
Item item = (Item) session.get(Item.class, new Long(1234));
tx.commit();
session.close(); // end of first session, item is detached
item.getId(); // The database identity is "1234"
item.setDescription("my new description");
Session session2 = sessionFactory.openSession();
Transaction tx2 = session2.beginTransaction();
Item item2 = (Item) session2.get(Item.class, new Long(1234));
session2.update(item); // Throws NonUniqueObjectException
tx2.commit();
session2.close();
To understand the cause of this exception, it’s important to understand detached objects and what happens when you call saveOrUpdate() (or just update()) on a detached object.
When we close an individual Hibernate Session, the persistent objects we are working with are detached. This means the data is still in the application’s memory, but Hibernate is no longer responsible for tracking changes to the objects.
If we then modify our detached object and want to update it, we have to reattach the object. During that reattachment process, Hibernate will check to see if there are any other copies of the same object. If it finds any, it has to tell us it doesn’t know what the “real” copy is any more. Perhaps other changes were made to those other copies that we expect to be saved, but Hibernate doesn’t know about them, because it wasn’t managing them at the time.
Rather than save possibly bad data, Hibernate tells us about the problem via the NonUniqueObjectException.
So what are we to do? In Hibernate 3, we have merge() (in Hibernate 2, use saveOrUpdateCopy()). This method will force Hibernate to copy any changes from other detached instances onto the instance you want to save, and thus merges all the changes in memory before the save.
Session session = sessionFactory1.openSession();
Transaction tx = session.beginTransaction();
Item item = (Item) session.get(Item.class, new Long(1234));
tx.commit();
session.close(); // end of first session, item is detached
item.getId(); // The database identity is "1234"
item.setDescription("my new description");
Session session2 = sessionFactory.openSession();
Transaction tx2 = session2.beginTransaction();
Item item2 = (Item) session2.get(Item.class, new Long(1234));
Item item3 = session2.merge(item); // Success!
tx2.commit();
session2.close();
It’s important to note that merge returns a reference to the newly updated version of the instance. It isn’t reattaching item to the Session. If you test for instance equality (item == item3), you’ll find it returns false in this case. You will probably want to work with item3 from this point forward.
It’s also important to note that the Java Persistence API (JPA) doesn’t have a concept of detached and reattached objects, and uses EntityManager.persist() and EntityManager.merge().
I’ve found in general that when using Hibernate, saveOrUpdate() is usually sufficient for my needs. I usually only need to use merge when I have objects that can have references to objects of the same type. Most recently, the cause of the exception was in the code validating that the reference wasn’t recursive. I was loading the same object into my session as part of the validation, causing the error.
Where have you encountered this problem? Did merge work for you or did you need another solution? Do you prefer to always use merge, or prefer to use it only as needed for specific cases
Try and check of your ServletResponse response
is an instanceof HttpServletResponse
like so:
if (response instanceof HttpServletResponse) {
response.sendRedirect(....);
}
Refer below :-
let arr = Array.apply(null, {length: 1000}).map(Function.call, Math.random)
/* will create array with 1000 elements */
I had the same problem and created 2 functions to create entities and translate them back to normal characters. The following methods translate any string to HTML entities and back on String prototype
/**
* Convert a string to HTML entities
*/
String.prototype.toHtmlEntities = function() {
return this.replace(/./gm, function(s) {
// return "&#" + s.charCodeAt(0) + ";";
return (s.match(/[a-z0-9\s]+/i)) ? s : "&#" + s.charCodeAt(0) + ";";
});
};
/**
* Create string from HTML entities
*/
String.fromHtmlEntities = function(string) {
return (string+"").replace(/&#\d+;/gm,function(s) {
return String.fromCharCode(s.match(/\d+/gm)[0]);
})
};
You can then use it as following:
var str = "Test´†®¥¨©??ø…ˆƒ?÷?™ƒ?æøp£¨ ƒ™en tést".toHtmlEntities();
console.log("Entities:", str);
console.log("String:", String.fromHtmlEntities(str));
Output in console:
Entities: Dit is e´†®¥¨©˙∫ø…ˆƒ∆÷∑™ƒ∆æø𣨠ƒ™en t£eést
String: Dit is e´†®¥¨©??ø…ˆƒ?÷?™ƒ?æøp£¨ ƒ™en t£eést
Use .getAbsolutePath() on your File object.
getClass().getResource("somefile").getFile().getAbsolutePath()
join is not a jQuery function .Its a javascript function.
The join() method joins the elements of an array into a string, and returns the string.The elements will be separated by a specified separator. The default separator is comma (,).
root folder changes for every directory os.walk finds. I solver that checking if root == directory
def _dir_list(self, dir_name, whitelist):
outputList = []
for root, dirs, files in os.walk(dir_name):
if root == dir_name: #This only meet parent folder
for f in files:
if os.path.splitext(f)[1] in whitelist:
outputList.append(os.path.join(root, f))
else:
self._email_to_("ignore")
return outputList
This works:

As Nikola pointed out in the comment below, in case the backup URL is invalid as well, some browsers will trigger the "error" event again which will result in an infinite loop. We can guard against this by simply nullifying the "error" handler via this.onerror=null;
.
I found I had to be logged in as a domain user.
It gave me this error when I was logged in as local machine Administrator and trying to add domain service account.
Logged in as domain user (but admin on machine) and it accepted the credentials.

@James Jithin - such exception can appear also when you have two different versions of beans and security schema in xsi:schemaLocation. It's the case in the snippet you have pasted:
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/security
http://www.springframework.org/schema/security/spring-security-3.1.xsd"
In my case changing them both to 3.1 solved the problem
Maybe this may help you as well. I was having some trouble getting my head wrapped around how socket.io worked, so I tried to boil an example down as much as I could.
I adapted this example from the example posted here: http://socket.io/get-started/chat/
First, start in an empty directory, and create a very simple file called package.json Place the following in it.
{
"dependencies": {}
}
Next, on the command line, use npm to install the dependencies we need for this example
$ npm install --save express socket.io
This may take a few minutes depending on the speed of your network connection / CPU / etc. To check that everything went as planned, you can look at the package.json file again.
$ cat package.json
{
"dependencies": {
"express": "~4.9.8",
"socket.io": "~1.1.0"
}
}
Create a file called server.js This will obviously be our server run by node. Place the following code into it:
var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);
app.get('/', function(req, res){
//send the index.html file for all requests
res.sendFile(__dirname + '/index.html');
});
http.listen(3001, function(){
console.log('listening on *:3001');
});
//for testing, we're just going to send data to the client every second
setInterval( function() {
/*
our message we want to send to the client: in this case it's just a random
number that we generate on the server
*/
var msg = Math.random();
io.emit('message', msg);
console.log (msg);
}, 1000);
Create the last file called index.html and place the following code into it.
<html>
<head></head>
<body>
<div id="message"></div>
<script src="/socket.io/socket.io.js"></script>
<script>
var socket = io();
socket.on('message', function(msg){
console.log(msg);
document.getElementById("message").innerHTML = msg;
});
</script>
</body>
</html>
You can now test this very simple example and see some output similar to the following:
$ node server.js
listening on *:3001
0.9575486415997148
0.7801907607354224
0.665313188219443
0.8101786421611905
0.890920243691653
If you open up a web browser, and point it to the hostname you're running the node process on, you should see the same numbers appear in your browser, along with any other connected browser looking at that same page.
You are getting this error because the value cannot be found in the range. String or integer doesn't matter. Best thing to do in my experience is to do a check first to see if the value exists.
I used CountIf below, but there is lots of different ways to check existence of a value in a range.
Public Sub test()
Dim rng As Range
Dim aNumber As Long
aNumber = 666
Set rng = Sheet5.Range("B16:B615")
If Application.WorksheetFunction.CountIf(rng, aNumber) > 0 Then
rowNum = Application.WorksheetFunction.Match(aNumber, rng, 0)
Else
MsgBox aNumber & " does not exist in range " & rng.Address
End If
End Sub
ALTERNATIVE WAY
Public Sub test()
Dim rng As Range
Dim aNumber As Variant
Dim rowNum As Long
aNumber = "2gg"
Set rng = Sheet5.Range("B1:B20")
If Not IsError(Application.Match(aNumber, rng, 0)) Then
rowNum = Application.Match(aNumber, rng, 0)
MsgBox rowNum
Else
MsgBox "error"
End If
End Sub
OR
Public Sub test()
Dim rng As Range
Dim aNumber As Variant
Dim rowNum As Variant
aNumber = "2gg"
Set rng = Sheet5.Range("B1:B20")
rowNum = Application.Match(aNumber, rng, 0)
If Not IsError(rowNum) Then
MsgBox rowNum
Else
MsgBox "error"
End If
End Sub
For my case, the culprit was the semicolon and double quotes in the password for prod DB. Our IT team use some tool to generate passwords, so it generated one with the semicolon and double quotes Connectionstring looks like

Got the password changed and it worked.
I had this same problem - some users could pull from git and everything ran fine. Some would pull and get a very similar exception:
Could not load file or assembly '..., Version=..., Culture=neutral, PublicKeyToken=...' or one of its dependencies. The system cannot find the file specified.
In my particular case it was AjaxMin, so the actual error looked like this but the details don't matter:
Could not load file or assembly 'AjaxMin, Version=4.95.4924.12383, Culture=neutral, PublicKeyToken=21ef50ce11b5d80f' or one of its dependencies. The system cannot find the file specified.
It turned out to be a result of the following actions on a Solution:
NuGet Package Restore was turned on for the Solution.
A Project was added, and a Nuget package was installed into it (AjaxMin in this case).
The Project was moved to different folder in the Solution.
The Nuget package was updated to a newer version.
And slowly but surely this bug started showing up for some users.
The reason was the Solution-level packages/respositories.config kept the old Project reference, and now had a new, second entry for the moved Project. In other words it had this before the reorg:
<repository path="..\Old\packages.config" />
And this after the reorg:
<repository path="..\Old\packages.config" />
<repository path="..\New\packages.config" />
So the first line now refers to a Project that, while on disk, is no longer part of my Solution.
With Nuget Package Restore on, both packages.config files were being read, which each pointed to their own list of Nuget packages and package versions. Until a Nuget package was updated to a newer version however, there weren't any conflicts.
Once a Nuget package was updated, however, only active Projects had their repositories listings updated. NuGet Package Restore chose to download just one version of the library - the first one it encountered in repositories.config, which was the older one. The compiler and IDE proceeded as though it chose the newer one. The result was a run-time exception saying the DLL was missing.
The answer obviously is to delete any lines from this file that referenced Projects that aren't in your Solution.
String is a reference type, so you don't need to (and cannot) use Nullable<T>
here. Just declare typeOfContract as string and simply check for null after getting it from the query string. Or use String.IsNullOrEmpty if you want to handle empty string values the same as null.
Since PostgreSQL JDBC driver version 8.4-701 the PreparedStatement#getGeneratedKeys()
is finally fully functional. We use it here almost one year in production to our full satisfaction.
In "plain JDBC" the PreparedStatement
needs to be created as follows to make it to return the keys:
statement = connection.prepareStatement(SQL, Statement.RETURN_GENERATED_KEYS);
You can download the current JDBC driver version here (which is at the moment still 8.4-701).
The first form, when used with an API that returns Boolean
and compared against Boolean.FALSE, will never throw a NullPointerException
.
The second form, when used with the java.util.Map
interface, also, will never throw a NullPointerException
because it returns a boolean
and not a Boolean
.
If you aren't concerned about consistent coding idioms, then you can pick the one you like, and in this concrete case it really doesn't matter. If you do care about consistent coding, then consider what you want to do when you check a Boolean
that may be NULL
.
I had a "fatal : bad revision" with Idea / Webstorm because I had a git directory inside another, without using properly submodules or subtrees.
I checked for .git
dirs with :
find ./ -name '.git' -print
For example see https://web.archive.org/web/20080506194329/http://www.arthurkoziel.com/2008/05/02/git-configuration/
The interesting part is
Colorized output:
git config --global color.branch auto git config --global color.diff auto git config --global color.interactive auto git config --global color.status auto
Simply, You can make this method static as below:
public static void startChronometer(){
mChronometer.start();
showElapsedTime();
}
you can call this function in other class as below:
MainActivity.startChronometer();
In market client on phones at least featured apps with high ratings get to display the promotional graphic.
This is the one that shows up on top even before you start searching the market for a specific app.
See this answer from Android market forum.
Edited: One of the google employee gives some clarifications here
Update: Both links above are now broken but the detailed information can be found here
Selected applications have the ability to be featured atop their respective categories. This is not a guaranteed feature, but uploading promotional graphics is something that we recommend.

For me, the main difference is that a script is interpreted, while a program is executed (i.e. the source is first compiled, and the result of that compilation is expected).
Wikipedia seems to agree with me on this :
Script :
"Scripts" are distinct from the core code of the application, which is usually written in a different language, and are often created or at least modified by the end-user.
Scripts are often interpreted from source code or bytecode, whereas the applications they control are traditionally compiled to native machine code.
Program :
The program has an executable form that the computer can use directly to execute the instructions.
The same program in its human-readable source code form, from which executable programs are derived (e.g., compiled)
<input type="text" disabled="disabled" />
See the W3C HTML Specification on the input tag for more information.
I don't know if this is useful for someone, but in my case the problem was that the name had different casing.
V1
in the service configuration - V
capital letter
v1
in Settings -- v
lower case
The only thing I did was to use the same casing and it worked.
Let's answer your questions one by one.
The instance that your base class reference is referring to is not an instance of your child class. There's nothing wrong.
More specifically:
Base derivedInstance = new Derived();
Base baseInstance = new Base();
Derived good = (Derived)derivedInstance; // OK
Derived fail = (Derived)baseInstance; // Throws InvalidCastException
For the cast to be successful, the instance that you're downcasting must be an instance of the class that you're downcasting to (or at least, the class you're downcasting to must be within the instance's class hierarchy), otherwise the cast will fail.
You could use pandas plot as @Bharath suggest:
import seaborn as sns
sns.set()
df.set_index('App').T.plot(kind='bar', stacked=True)
Output:
Updated:
from matplotlib.colors import ListedColormap
df.set_index('App')\
.reindex_axis(df.set_index('App').sum().sort_values().index, axis=1)\
.T.plot(kind='bar', stacked=True,
colormap=ListedColormap(sns.color_palette("GnBu", 10)),
figsize=(12,6))
Updated Pandas 0.21.0+ reindex_axis
is deprecated, use reindex
from matplotlib.colors import ListedColormap
df.set_index('App')\
.reindex(df.set_index('App').sum().sort_values().index, axis=1)\
.T.plot(kind='bar', stacked=True,
colormap=ListedColormap(sns.color_palette("GnBu", 10)),
figsize=(12,6))
Output:
just remove float: left
and replace align with margin: 0 auto
and it will be centered.
You can use console.log()
in Firebug or Chrome to get a good object view here, like this:
$.getJSON('my.json', function(data) {
console.log(data);
});
If you just want to view the string, look at the Resource view in Chrome or the Net view in Firebug to see the actual string response from the server (no need to convert it...you received it this way).
If you want to take that string and break it down for easy viewing, there's an excellent tool here: http://json.parser.online.fr/
Copy and paste this code into your Activity
and when it is executed it will Toast
the device's screen size category.
int screenSize = getResources().getConfiguration().screenLayout &
Configuration.SCREENLAYOUT_SIZE_MASK;

switch(screenSize) {
case Configuration.SCREENLAYOUT_SIZE_LARGE:
toastMsg = "Large screen";
break;
case Configuration.SCREENLAYOUT_SIZE_NORMAL:
toastMsg = "Normal screen";
break;
case Configuration.SCREENLAYOUT_SIZE_SMALL:
toastMsg = "Small screen";
break;
default:
toastMsg = "Screen size is neither large, normal or small";
}
Toast.makeText(this, toastMsg, Toast.LENGTH_LONG).show();
DatePicker selected value change event code below

Suppose you have two commits in local branch:
D---E master
/
A---B---C---F origin/master
After "git pull", will be:
D--------E
/ \
A---B---C---F----G master, origin/master
After "git pull --rebase", there will be no merge point G. Note that D and E become different commits:
A---B---C---F---D'---E' master, origin/master
The selected answer does not work.
declare @str varchar(50)='79D136'
select 1 where @str NOT LIKE '%[^0-9]%'
I don't have a solution but know of this potential pitfall. The same goes if you substitute the letter 'D' for 'E' which is scientific notation.
As others have noted, embedding function pointers directly inside your structure is usually reserved for special purposes, like a callback function.
What you probably want is something more like a virtual method table.
typedef struct client_ops_t client_ops_t;
typedef struct client_t client_t, *pno;
struct client_t {
/* ... */
client_ops_t *ops;
};
struct client_ops_t {
pno (*AddClient)(client_t *);
pno (*RemoveClient)(client_t *);
};
pno AddClient (client_t *client) { return client->ops->AddClient(client); }
pno RemoveClient (client_t *client) { return client->ops->RemoveClient(client); }
Now, adding more operations does not change the size of the client_t
structure. Now, this kind of flexibility is only useful if you need to define many kinds of clients, or want to allow users of your client_t
interface to be able to augment how the operations behave.
This kind of structure does appear in real code. The OpenSSL BIO layer looks similar to this, and also UNIX device driver interfaces have a layer like this.
If you want to examine elements inside a dataframe you should not be using ls()
which only looks at the names of objects in the current workspace (or if used inside a function in the current environment). Rownames or elements inside such objects are not visible to ls()
(unless of course you add an environment argument to the ls(.)
-call). Try using grep()
which is the workhorse function for pattern matching of character vectors:
result <- a[ grep("blue", a$x) , ] # Note need to use `a$` to get at the `x`
If you want to use subset then consider the closely related function grepl()
which returns a vector of logicals can be used in the subset argument:
subset(a, grepl("blue", a$x))
x
2 blue1
3 blue2
Edit: Adding one "proper" use of glob2rx within subset():
result <- subset(a, grepl(glob2rx("blue*") , x) )
result
x
2 blue1
3 blue2
I don't think I actually understood glob2rx
until I came back to this question. (I did understand the scoping issues that were ar the root of the questioner's difficulties. Anybody reading this should now scroll down to Gavin's answer and upvote it.)
You can't do it through jQuery alone; you'll need a combination of Ajax (which you can do with jQuery) and a PHP back-end. A very simple version might look like this:
HTML:
<img class="foo" src="img.jpg" />
<img class="foo" src="img2.jpg" />
<img class="foo" src="img3.jpg" />
Javascript:
$("img.foo").onclick(function()
{
// Get the src of the image
var src = $(this).attr("src");
// Send Ajax request to backend.php, with src set as "img" in the POST data
$.post("/backend.php", {"img": src});
});
PHP (backend.php):
<?php
// do any authentication first, then add POST variable to session
$_SESSION['imgsrc'] = $_POST['img'];
?>
If you are inside the fragment then you write the following line of code inside your on click listener,
getActivity().onBackPressed();
this works perfectly for me.
SQLite has had to sacrifice other characteristics that some people find useful, such as high concurrency, fine-grained access control, a rich set of built-in functions, stored procedures, esoteric SQL language features, XML and/or Java extensions, tera- or peta-byte scalability, and so forth

Forget about finding a IDE to write/run/compile assembler on Mac. But, remember mac is UNIX. See http://asm.sourceforge.net/articles/linasm.html. A decent guide (though short) to running assembler via GCC on Linux. You can mimic this. Macs use Intel chips so you want to look at Intel syntax.

This is because according to CSS 2.1, the effect of position: relative
on table elements is undefined. Illustrative of this, position: relative
has the desired effect on Chrome 13, but not on Firefox 4. Your solution here is to add a div
around your content and put the position: relative
on that div
instead of the td
. The following illustrates the results you get with the position: relative
(1) on a div
good), (2) on a td
(no good), and finally (3) on a div
inside a td
(good again).
<table>_x000D_
<tr>_x000D_
<td>_x000D_
<div style="position:relative;">_x000D_
<span style="position:absolute; left:150px;">_x000D_
Absolute span_x000D_

MacPorts will install ant for you in MacOSX 10.9. Just use

See the Java Persistence book: Identity and Sequencing
The relevant part for your question is the No Primary Key section:
Sometimes your object or table has no primary key. The best solution in this case is normally to add a generated id to the object and table. If you do not have this option, sometimes there is a column or set of columns in the table that make up a unique value. You can use this unique set of columns as your id in JPA. The JPA
Id
does not always have to match the database table primary key constraint, nor is a primary key or a unique constraint required.If your table truly has no unique columns, then use all of the columns as the id. Typically when this occurs the data is read-only, so even if the table allows duplicate rows with the same values, the objects will be the same anyway, so it does not matter that JPA thinks they are the same object. The issue with allowing updates and deletes is that there is no way to uniquely identify the object's row, so all of the matching rows will be updated or deleted.
If your object does not have an id, but its' table does, this is fine. Make the object an
Embeddable
object, embeddable objects do not have ids. You will need aEntity
that contains thisEmbeddable
to persist and query it.

You can basically switch the class using [ngClass]
for example
<button [ngClass]="{'active': selectedItem === 'item1'}" (click)="selectedItem = 'item1'">Button One</button>
<button [ngClass]="{'active': selectedItem === 'item2'}" (click)="selectedItem = 'item2'">Button Two</button>
One notable difference in Python 2 is that if you're using ensure_ascii=False
, dump
will properly write UTF-8 encoded data into the file (unless you used 8-bit strings with extended characters that are not UTF-8):
dumps
on the other hand, with ensure_ascii=False
can produce a str
or unicode
just depending on what types you used for strings:
Serialize obj to a JSON formatted str using this conversion table. If ensure_ascii is False, the result may contain non-ASCII characters and the return value may be a
unicode
instance.
(emphasis mine). Note that it may still be a str
instance as well.
Thus you cannot use its return value to save the structure into file without checking which
format was returned and possibly playing with unicode.encode
.
This of course is not valid concern in Python 3 any more, since there is no more this 8-bit/Unicode confusion.
As for load
vs loads
, load
considers the whole file to be one JSON document, so you cannot use it to read multiple newline limited JSON documents from a single file.
A very pythonic and practical way to do it is by using the string join()
method:
str.join(iterable)
The official Python documentations says:
Return a string which is the concatenation of the strings in iterable... The separator between elements is the string providing this method.
How to use it?
Remember: this is a string method.
This method will be applied to the str
above, which reflects the string that will be used as separator of the items in the iterable.
Let's have some practical example!
iterable = "BINGO"
separator = " " # A whitespace character.
# The string to which the method will be applied
separator.join(iterable)
> 'B I N G O'
In practice you would do it like this:
iterable = "BINGO"
" ".join(iterable)
> 'B I N G O'
But remember that the argument is an iterable, like a string, list, tuple. Although the method returns a string.
iterable = ['B', 'I', 'N', 'G', 'O']
" ".join(iterable)
> 'B I N G O'
What happens if you use a hyphen as a string instead?
iterable = ['B', 'I', 'N', 'G', 'O']
"-".join(iterable)
> 'B-I-N-G-O'
Your key is a string and your value is an int. Your code won't work because it cannot look up the random int you pass. Also, please provide full code
Here is Vishwanath's solution slightly rewritten with comments :
function setStyle(cssRules, aSelector, aStyle){
for(var i = 0; i < cssRules.length; i++) {
if(cssRules[i].selectorText && cssRules[i].selectorText.toLowerCase() == aSelector.toLowerCase()) {
cssRules[i].style.cssText = aStyle;
return true;
}
}
return false;
}
function createCSSSelector(selector, style) {
var doc = document;
var allSS = doc.styleSheets;
if(!allSS) return;
var headElts = doc.getElementsByTagName("head");
if(!headElts.length) return;
var styleSheet, media, iSS = allSS.length; // scope is global in a function
/* 1. search for media == "screen" */
while(iSS){ --iSS;
if(allSS[iSS].disabled) continue; /* dont take into account the disabled stylesheets */
media = allSS[iSS].media;
if(typeof media == "object")
media = media.mediaText;
if(media == "" || media=='all' || media.indexOf("screen") != -1){
styleSheet = allSS[iSS];
iSS = -1; // indication that media=="screen" was found (if not, then iSS==0)
break;
}
}
/* 2. if not found, create one */
if(iSS != -1) {
var styleSheetElement = doc.createElement("style");
styleSheetElement.type = "text/css";
headElts[0].appendChild(styleSheetElement);
styleSheet = doc.styleSheets[allSS.length]; /* take the new stylesheet to add the selector and the style */
}
/* 3. add the selector and style */
switch (typeof styleSheet.media) {
case "string":
if(!setStyle(styleSheet.rules, selector, style));
styleSheet.addRule(selector, style);
break;
case "object":
if(!setStyle(styleSheet.cssRules, selector, style));
styleSheet.insertRule(selector + "{" + style + "}", styleSheet.cssRules.length);
break;
}
Accessing batch parameters can be simple with %1, %2, ... %9 or also %*,
but only if the content is simple.
There is no simple way for complex contents like "&"^&
, as it's not possible to access %1 without producing an error.
set var=%1
set "var=%1"
set var=%~1
set "var=%~1"
The lines expand to
set var="&"&
set "var="&"&"
set var="&"&
set "var="&"&"
And each line fails, as one of the &
is outside of the quotes.
It can be solved with reading from a temporary file a remarked version of the parameter.
@echo off
SETLOCAL DisableDelayedExpansion
SETLOCAL
for %%a in (1) do (
set "prompt="
echo on
for %%b in (1) do rem * #%1#
@echo off
) > param.txt
ENDLOCAL
for /F "delims=" %%L in (param.txt) do (
set "param1=%%L"
)
SETLOCAL EnableDelayedExpansion
set "param1=!param1:*#=!"
set "param1=!param1:~0,-2!"
echo %%1 is '!param1!'
The trick is to enable echo on
and expand the %1 after a rem
statement (works also with %2 .. %*
).
So even "&"&
could be echoed without producing an error, as it is remarked.
But to be able to redirect the output of the echo on
, you need the two for-loops.
The extra characters * #
are used to be safe against contents like /?
(would show the help for REM
).
Or a caret ^ at the line end could work as a multiline character, even in after a rem
.
Then reading the rem parameter output from the file, but carefully.
The FOR /F should work with delayed expansion off, else contents with "!" would be destroyed.
After removing the extra characters in param1
, you got it.
And to use param1
in a safe way, enable the delayed expansion.
I've been in this (Twitter) industry for a long time and witnessed lots of changes in Twitter API and documentation. I would like to clarify one thing to you. There is no way to surpass 3200 tweets limit. Twitter doesn't provide this data even in its new premium API.
The only way someone can surpass this limit is by saving the tweets of an individual Twitter user.
There are tools available which claim to have a wide database and provide more than 3200 tweets. Few of them are followersanalysis.com, keyhole.co which I know of.
The obvious thing to do is read the documentation.
But to help: substr($str, $start, $end);
$str
is your text
$start
is the character index to begin at. In your case, it is likely 0 which means the very beginning.
$end
is where to truncate at. Suppose you wanted to end at 15 characters, for example. You would write it like this:
<?php
$text = "long text that should be truncated";
echo substr($text, 0, 15);
?>
and you would get this:
long text that
makes sense?
EDIT
The link you gave is a function to find the last white space after chopping text to a desired length so you don't cut off in the middle of a word. However, it is missing one important thing - the desired length to be passed to the function instead of always assuming you want it to be 25 characters. So here's the updated version:
function truncate($text, $chars = 25) {
if (strlen($text) <= $chars) {
return $text;
}
$text = $text." ";
$text = substr($text,0,$chars);
$text = substr($text,0,strrpos($text,' '));
$text = $text."...";
return $text;
}
So in your case you would paste this function into the functions.php file and call it like this in your page:
$post = the_post();
echo truncate($post, 100);
This will chop your post down to the last occurrence of a white space before or equal to 100 characters. Obviously you can pass any number instead of 100. Whatever you need.
htaccess files affect the directory they are placed in and all sub-directories, that is an htaccess file located in your root directory (yoursite.com) would affect yoursite.com/content, yoursite.com/content/contents, etc.
Your code isn't working because c:/ or d:/ is totally wrong for linux just use /mnt/c or/mnt/c
From your local windows10-ubuntu bash use this command:

Then type your remote server password if there is need.
for upload: (from d:/ubuntu to remote server ) :

Then type your remote server password if there is need. note: I tested and it worked.

CSS has become a very powerful tool over the years and it has hacks for a lot of things javaScript can do
There is a hack in CSS for using conditional statements/logic.
It involves using the symbol '~'
Let me further illustrate with an example.
Let's say you want a background to slide into the page when a button is clicked. All you need to do is use a radio checkbox. Style the label for the radio underneath the button so that when the button is pressed the checkbox is also pressed.
Then you use the code below
.checkbox:checked ~ .background{
opacity:1
width: 100%
}
This code simply states IF the checkbox is CHECKED then open up the background ELSE leave it as it is.
If I understand your problem correctly, you are calling a method instead of passing it as a parameter. Try the following:
myTimer.Elapsed += PlayMusicEvent;
where
public void PlayMusicEvent(object sender, ElapsedEventArgs e)
{
music.player.Stop();
System.Timers.Timer myTimer = (System.Timers.Timer)sender;
myTimer.Stop();
}
But you need to think about where to store your note.
A great substitute for np.isnan() and pd.isnull() is
for i in range(0,a.shape[0]):
if(a[i]!=a[i]):
//do something here
//a[i] is nan
since only nan is not equal to itself.
What ever instance you are using to call the void method , You can just use ,Verfiy
For Example:
In My case its _Log
is the instance and LogMessage
is the method to be tested:
try
{
this._log.Verify(x => x.LogMessage(Logger.WillisLogLevel.Info, Logger.WillisLogger.Usage, "Created the Student with name as"), "Failure");
}
Catch
{
Assert.IsFalse(ex is Moq.MockException);
}
Is the Verify
throws an exception due to failure of the method the test would Fail ?

print "Process time: " + (time.time() - start)
time.time()
gives you seconds since the epoch. Because this is a standardized time in seconds, you can simply subtract the start time from the end time to get the process time (in seconds). time.clock()
is good for benchmarking, but I have found it kind of useless if you want to know how long your process took. For example, it's much more intuitive to say "my process takes 10 seconds" than it is to say "my process takes 10 processor clock units"
>>> start = time.time(); sum([each**8.3 for each in range(1,100000)]) ; print (time.time() - start)
3.4001404476250935e+45
0.0637760162354
>>> start = time.clock(); sum([each**8.3 for each in range(1,100000)]) ; print (time.clock() - start)
3.4001404476250935e+45
0.05
In the first example above, you are shown a time of 0.05 for time.clock() vs 0.06377 for time.time()
>>> start = time.clock(); time.sleep(1) ; print "process time: " + (time.clock() - start)
process time: 0.0
>>> start = time.time(); time.sleep(1) ; print "process time: " + (time.time() - start)
process time: 1.00111794472
In the second example, somehow the processor time shows "0" even though the process slept for a second. time.time()
correctly shows a little more than 1 second.
Could it be simpler?!
uint8_t hex(char ch) {
uint8_t r = (ch > 57) ? (ch - 55) : (ch - 48);

return count;
*out = (*out << 4) | hex(*in++);

ConfigObj is a good alternative to ConfigParser which offers a lot more flexibility:
It has some draw backs:
=
… (pull request)fuabr =
instead of just fubar
which looks weird and wrong.If you want the accepted answer to work in JQuery 3 change the code like this:
var scrollItems = menuItems.map(function () {
var id = $(this).attr("href");
try {
var item = $(id);
if (item.length) {
return item;
}
} catch {}
});
I also added a try-catch to prevent javascript from crashing if there is no element by that id. Feel free to improve it even more ;)
If you are able to use the bash shell, you can consider simply running the R code from within a bash script and piping the stdout and stderr streams to a file. Here is an example using a heredoc:
File: test.sh
#!/bin/bash
# this is a bash script
echo "Hello World, this is bash"
test1=$(echo "This is a test")
echo "Here is some R code:"
Rscript --slave --no-save --no-restore - "$test1" <<EOF
## R code
cat("\nHello World, this is R\n")
args <- commandArgs(TRUE)
bash_message<-args[1]
cat("\nThis is a message from bash:\n")
cat("\n",paste0(bash_message),"\n")
EOF
# end of script
Then when you run the script with both stderr and stdout piped to a log file:
$ chmod +x test.sh
$ ./test.sh
$ ./test.sh &>test.log
$ cat test.log
Hello World, this is bash
Here is some R code:
Hello World, this is R
This is a message from bash:
This is a test
Other things to look at for this would be to try simply pipping the stdout and stderr right from the R heredoc into a log file; I haven't tried this yet but it will probably work too.
Unload the entire solution and then reload it again. Then Rebuild the solution. This resolved the issue for me.
parseInt(num) === num
when passed a number, parseInt()
just returns the number as int:
parseInt(3.3) === 3.3 // false because 3 !== 3.3
parseInt(3) === 3 // true
Yes:
df -k .
for the current directory.
df -k /some/dir
if you want to check a specific directory.
You might also want to check out the stat(1)
command if your system has it. You can specify output formats to make it easier for your script to parse. Here's a little example:
$ echo $(($(stat -f --format="%a*%S" .)))
If you want to make it in python you need check this code in your workbench. also write like this. we created a popup box with python.
msgBox = QMessageBox()
msgBox.setText("The document has been modified.")
msgBox.setInformativeText("Do you want to save your changes?")
msgBox.setStandardButtons(QMessageBox.Save | QMessageBox.Discard | QMessageBox.Cancel)
msgBox.setDefaultButton(QMessageBox.Save)
ret = msgBox.exec_()
Make sure your config is set to the project -
gcloud config set project [PROJECT_ID]
Run a checklist of the Clusters in the account:
gcloud container clusters list
Check the output :
NAME LOCATION MASTER_VERSION MASTER_IP MACHINE_TYPE NODE_VE. alpha-cluster asia-south1-a 1.9.7-gke.6 35.200.254.78 f1-micro 1.9.7- NUM_NODES STATUS gke.6 3 RUNNING
Run the following cmd to fetch credentials for your running cluster:
gcloud container clusters get-credentials your-cluster-name --zone your-zone --project your-project
Fetching cluster endpoint and auth data. kubeconfig entry generated for alpha-cluster.
kubectl
such as below to list all pods in the current namespace, with more details:$ kubectl get nodes -o wide
Should be good to go.
You cannot do this in any released version of C#, nor in the upcoming C# 4.0. It's not a C# limitation, either - there's no "interface" constraint in the CLR itself.
I know that the question was how to do it with Jquery, but you can achieve the same affect with simple css and just a little jquery...
For example, you have a div with 'box' class, add the following css
.box {
background-color: black;
-webkit-transition: background 0.5s linear;
-moz-transition: background 0.5s linear;
-ms-transition: background 0.5s linear;
-o-transition: background 0.5s linear;
transition: background 0.5s linear;
}
and then use AddClass function to add another class with different background color like 'box highlighted' or something like that with the following css:
.box.highlighted {
background-color: white;
}
I am a beginner and maybe there are some disadvantages of this method but maybe it'll be helpful for somebody
Here's a codepen: https://codepen.io/anon/pen/baaLYB
Yes, you can set cookie in the AJAX request in the server-side code just as you'd do for a normal request since the server cannot differentiate between a normal request or an AJAX request.
AJAX requests are just a special way of requesting to server, the server will need to respond back as in any HTTP request. In the response of the request you can add cookies.
Using $emit and $broadcast, (as mentioned by walv in the comments above)
To fire an event upwards (from child to parent)
$scope.$emit('myTestEvent', 'Data to send');
To fire an event downwards (from parent to child)
$scope.$broadcast('myTestEvent', {
someProp: 'Sending you some data'
});
and finally to listen
$scope.$on('myTestEvent', function (event, data) {
console.log(data);
});

I found the nice resource Standard C++ Containers. Probably this is what you all looking for.
VECTOR
Constructors
vector<T> v; Make an empty vector. O(1)
vector<T> v(n); Make a vector with N elements. O(n)
vector<T> v(n, value); Make a vector with N elements, initialized to value. O(n)
vector<T> v(begin, end); Make a vector and copy the elements from begin to end. O(n)
Accessors
v[i] Return (or set) the I'th element. O(1)
v.at(i) Return (or set) the I'th element, with bounds checking. O(1)
v.size() Return current number of elements. O(1)
v.empty() Return true if vector is empty. O(1)
v.begin() Return random access iterator to start. O(1)
v.end() Return random access iterator to end. O(1)
v.front() Return the first element. O(1)
v.back() Return the last element. O(1)
v.capacity() Return maximum number of elements. O(1)
Modifiers
v.push_back(value) Add value to end. O(1) (amortized)
v.insert(iterator, value) Insert value at the position indexed by iterator. O(n)
v.pop_back() Remove value from end. O(1)
v.assign(begin, end) Clear the container and copy in the elements from begin to end. O(n)
v.erase(iterator) Erase value indexed by iterator. O(n)
v.erase(begin, end) Erase the elements from begin to end. O(n)
For other containers, refer to the page.
yes, using *arg passing args to a function will make python unpack the values in arg and pass it to the function.
so:
>>> def printer(*args):
print args
>>> printer(2,3,4)
(2, 3, 4)
>>> printer(*range(2, 5))
(2, 3, 4)
>>> printer(range(2, 5))
([2, 3, 4],)
>>>
The title
attribute displays a tooltip when the mouse is hovering the element. While this is a great addition, it doesn't help people who cannot use the mouse (due to mobility disabilities) or people who can't see this tooltip (e.g.: people with visual disabilities or people who use a screen reader).
As such, the mindful approach here would be to serve all users. I would add both title
and aria-label
attributes (serving different types of users and different types of usage of the web).
Here's a good article that explains aria-label
in depth
Instead of using a sheet name, in case you don't know or can't open the excel file to check in ubuntu (in my case, Python 3.6.7, ubuntu 18.04), I use the parameter index_col (index_col=0 for the first sheet)
import pandas as pd
file_name = 'some_data_file.xlsx'
df = pd.read_excel(file_name, index_col=0)
print(df.head()) # print the first 5 rows
Complete reference is not available for the mentioned files, as they are extensible by various plug-ins.
Basically, .project files store project-settings, such as builder and project nature settings, while .classpath files define the classpath to use during running. The classpath files contains src and target entries that correspond with folders in the project; the con entries are used to describe some kind of "virtual" entries, such as the JVM libs or in case of eclipse plug-ins dependencies (normal Java project dependencies are displayed differently, using a special src entry).
On Webpack 2 I tried all 12 devtool options. The following options link to the original file in the console and preserve line numbers. See the note below re: lines only.
https://webpack.js.org/configuration/devtool

build rebuild quality look
eval-source-map slow pretty fast original source worst
inline-source-map slow slow original source medium
cheap-module-eval-source-map medium fast original source (lines only) worst
inline-cheap-module-source-map medium pretty slow original source (lines only) best
lines only
Source Maps are simplified to a single mapping per line. This usually means a single mapping per statement (assuming you author is this way). This prevents you from debugging execution on statement level and from settings breakpoints on columns of a line. Combining with minimizing is not possible as minimizers usually only emit a single line.
REVISITING THIS
On a large project I find ... eval-source-map rebuild time is ~3.5s ... inline-source-map rebuild time is ~7s
<div class="d-flex justify-content-start">hello</div>
<div class="d-flex justify-content-end">hello</div>
<div class="d-flex justify-content-center">hello</div>
<div class="d-flex justify-content-between">hello</div>
<div class="d-flex justify-content-around">hello</div>
Put the fields that you want to center, right or left according above division.
You don't need javascript for doing so. Just delete the onClick and write the php Admin.php
file like this:
<!-- HTML STARTS-->
<?php
//If all the required fields are filled
if (!empty($GET_['fullname'])&&!empty($GET_['email'])&&!empty($GET_['name']))
{
function addNewContact()
{
$new = '{';
$new .= '"fullname":"' . $_GET['fullname'] . '",';
$new .= '"email":"' . $_GET['email'] . '",';
$new .= '"phone":"' . $_GET['phone'] . '",';
$new .= '}';
return $new;
}
function saveContact()
{
$datafile = fopen ("data/data.json", "a+");
if(!$datafile){
echo "<script>alert('Data not existed!')</script>";
}
else{
$contact_list = $contact_list . addNewContact();
file_put_contents("data/data.json", $contact_list);
}
fclose($datafile);
}
// Call the function saveContact()
saveContact();
echo "Thank you for joining us";
}
else //If the form is not submited or not all the required fields are filled
{ ?>
<form>
<fieldset>
<legend>Add New Contact</legend>
<input type="text" name="fullname" placeholder="First name and last name" required /> <br />
<input type="email" name="email" placeholder="[email protected]" required /> <br />
<input type="text" name="phone" placeholder="Personal phone number: mobile, home phone etc." required /> <br />
<input type="submit" name="submit" class="button" value="Add Contact"/>
<input type="button" name="cancel" class="button" value="Reset" />
</fieldset>
</form>
<?php }
?>
<!-- HTML ENDS -->
Thought I don't like the PHP bit. Do you REALLY want to create a file for contacts? It'd be MUCH better to use a mysql database. Also, adding some breaks to that file would be nice too...
Other thought, IE doesn't support placeholder.
I found at least three ways of doing this:
public getters
on your entity that you try to serialize;public getters
. This will change the default for Jackson from Visbility=DEFAULT
to @JsonAutoDetect(fieldVisibility = JsonAutoDetect.Visibility.ANY)
where any access modifiers are accepted;ObjectMapper
globally by setting objectMapperInstance.setVisibility(JsonMethod.FIELD, Visibility.ANY);
. This should be avoided if you don't need this functionality globally.Choose based on your needs.
You were on the right track with response.getOutputStream()
, but you're not using its output anywhere in your code. Essentially what you need to do is to stream the PDF file's bytes directly to the output stream and flush the response. In Spring you can do it like this:
@RequestMapping(value="/getpdf", method=RequestMethod.POST)
public ResponseEntity<byte[]> getPDF(@RequestBody String json) {
// convert JSON to Employee
Employee emp = convertSomehow(json);
// generate the file
PdfUtil.showHelp(emp);
// retrieve contents of "C:/tmp/report.pdf" that were written in showHelp
byte[] contents = (...);
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_PDF);
// Here you have to set the actual filename of your pdf
String filename = "output.pdf";
headers.setContentDispositionFormData(filename, filename);
headers.setCacheControl("must-revalidate, post-check=0, pre-check=0");
ResponseEntity<byte[]> response = new ResponseEntity<>(contents, headers, HttpStatus.OK);
return response;
}
Notes:
showHelp
is not a good ideabyte[]
: example hereshowHelp()
to avoid overwriting the file if two users send a request at the same timeUse the Java Calendar
class.
Calendar calendar = Calendar.getInstance();
int day = calendar.get(Calendar.DAY_OF_WEEK);
switch (day) {
case Calendar.SUNDAY:
// Current day is Sunday
break;
case Calendar.MONDAY:
// Current day is Monday
break;
case Calendar.TUESDAY:
// etc.
break;
}
The easiest way is probably to use xvfb-run:
DISPLAY=:1 xvfb-run java -jar selenium-server-standalone-2.0b3.jar
xvfb-run does the whole X authority dance for you, give it a try!
My solution
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(Environment.getExternalStorageDirectory().getPath()+"/your_app_folder/"+"your_picture_saved_name"+".png")), "image/*");
context.startActivity(intent);
git stash save
is deprecated as of 2.15.x/2.16, instead you can use git stash push -m "message"
You can use it like this:
git stash push -m "message"
where "message" is your note for that stash.
In order to retrieve the stash you can use: git stash list
. This will output a list like this, for example:
stash@{0}: On develop: perf-spike
stash@{1}: On develop: node v10
Then you simply use apply
giving it the stash@{index}
:
git stash apply stash@{1}
References git stash man page
ModelName::find($id, ['name', 'surname']);
In PHP, use mysqli_real_escape_string.
Example from the PHP Manual:
<?php
$link = mysqli_connect("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
mysqli_query($link, "CREATE TEMPORARY TABLE myCity LIKE City");
$city = "'s Hertogenbosch";
/* this query will fail, cause we didn't escape $city */
if (!mysqli_query($link, "INSERT into myCity (Name) VALUES ('$city')")) {
printf("Error: %s\n", mysqli_sqlstate($link));
}
$city = mysqli_real_escape_string($link, $city);
/* this query with escaped $city will work */
if (mysqli_query($link, "INSERT into myCity (Name) VALUES ('$city')")) {
printf("%d Row inserted.\n", mysqli_affected_rows($link));
}
mysqli_close($link);
?>
Although ANSI C does not have this mechanism, it is possible to use itoa() as a shortcut:
char buffer [33];
itoa (i,buffer,2);
printf ("binary: %s\n",buffer);
Here's the origin:
It is non-standard C, but K&R mentioned the implementation in the C book, so it should be quite common. It should be in stdlib.h.

The article "Why is my list black? An Android optimization" in the Android Developers Blog has a thorough explanation of why the list background turns black when scrolling. Simple answer: set cacheColorHint on your list to transparent (#00000000).
Copy the contents of the PATH settings to a notepad and check if the location for the 1.4.2 comes before that of the 7. If so, remove the path to 1.4.2 in the PATH setting and save it.
After saving and applying "Environment Variables" close and reopen the cmd line. In XP the path does no get reflected in already running programs.
You may try this one

} else {
textView.setTextAppearance(getActivity(), R.style.Lato_Bold);
}
It's not a jQuery feature but a feature for debugging purposes. You can for instance log something to the console when something happens. For instance:
$('#someButton').click(function() {
console.log('#someButton was clicked');
// do something
});
You'd then see #someButton was clicked
in Firebug’s “Console” tab (or another tool’s console — e.g. Chrome’s Web Inspector) when you would click the button.
For some reasons, the console object could be unavailable. Then you could check if it is - this is useful as you don't have to remove your debugging code when you deploy to production:
if (window.console && window.console.log) {
// console is available
}
This error can be due to many many things.
The key here seems the hint about error reading
. I see you are working on a flash drive or something similar? Try to run the install on a local folder owned by your current user.
You could also try with sudo
, that might solve a permission problem if that's the case.
Another reason why it cannot read could be because it has not downloaded correctly, or saved correctly. A little problem in your network could have caused that, and the cache clean would remove the files and force a refetch but that does not solve your problem. That means it would be more on the save part, maybe it didn't save because of permissions, maybe it didn't not save correctly because it was lacking disk space...
You need to alter your table. Increase the column width using a DDL statement.
please see here
http://dba-oracle.com/t_alter_table_modify_column_syntax_example.htm
You need to read up on event bubbling and for sure remove inline event handling if you have jQuery anyway
Test the click on the div and examine the target
$(".expandable-panel-heading").on("click",function (e) {
if (e.target.id =="ancherComplaint") { // or test the tag
e.preventDefault(); // or e.stopPropagation()
markActiveLink(e.target);
}
else alert('123');
});
function markActiveLink(el) {
alert(el.id);
}
I tried all the above solutions. but it didn't work.
The solution was to restart eclipse !!!!!!!
hope this will help someone :)
From Firefox 34 onwards you now have an option for Storage Inspector, which you can enable it from developer tools settings
Once there, you can enable the Storage
options under Default Firefox Developer tools
Updated 27-3-16
Firefox 48.0a1 now supports Cookies editing.
Updated 3-4-16
Firefox 48.0a1 now supports localStorage and sessionStorage editing.
Updated 02-08-16
Firefox 48 (stable release) and onward supports editing of all storage types, except IndexedDB

List can be instantiated by any class implementing the interface.By this way,Java provides us polymorphic behaviour.See the example below:
List<String> list = new ArrayList<String>();
Instead of instantiating an ArrayList directly,I am using a List to refer to ArrayList object so that we are using only the List interface methods and do not care about its actual implementation.
Examples of classes implementing List are ArrayList,LinkedList,Vector.You probably want to create a List depending upon your requirements.
Example:- a LinkedList is more useful when you hve to do a number of inertion or deletions .Arraylist is more performance intensive as it is backed by a fixed size array and array contents have to be changed by moving or regrowing the array.
Again,using a List we can simply change our object instantiation without changing any code further in your programs.
Suppose we are using ArrayList<String> value = new ArrayList<String>();
we may use a specific method of ArrrayList and out code will not be robust
By using List<String> value = new ArrayList<String>();
we are making sure we are using only List interface methods..and if we want to change it to a LinkedList we simply have to change the code :
List<String> value = new ArrayList<String>();
------ your code uses List interface methods.....
value = new LinkedList<String>();
-----your code still uses List interface methods and we do not have to change anything---- and we dont have to change anything in our code further
By the way a LinkedList also works a Deque which obviously also you cannot instantiate as it is also an interface
There are obviously plenty of answers, but this one answers it very nicely (with source)
#pragma omp for
only delegates portions of the loop for different threads in the current team. A team is the group of threads executing the program. At program start, the team consists only of a single member: the master thread that runs the program.To create a new team of threads, you need to specify the parallel keyword. It can be specified in the surrounding context:
#pragma omp parallel { #pragma omp for for(int n = 0; n < 10; ++n) printf(" %d", n); }
and:
What are: parallel, for and a team
The difference between parallel, parallel for and for is as follows:
A team is the group of threads that execute currently. At the program beginning, the team consists of a single thread. A parallel construct splits the current thread into a new team of threads for the duration of the next block/statement, after which the team merges back into one. for divides the work of the for-loop among the threads of the current team.
It does not create threads, it only divides the work amongst the threads of the currently executing team. parallel for is a shorthand for two commands at once: parallel and for. Parallel creates a new team, and for splits that team to handle different portions of the loop. If your program never contains a parallel construct, there is never more than one thread; the master thread that starts the program and runs it, as in non-threading programs.
The name
attribute is used when sending data in a form submission. Different controls respond differently. For example, you may have several radio buttons with different id
attributes, but the same name
. When submitted, there is just the one value in the response - the radio button you selected.
Of course, there's more to it than that, but it will definitely get you thinking in the right direction.

The issue seems to be resolved in Python version 3.4.2.
testVar = input("Ask user for something.")
Will work fine.
The SQLite documentation is a great reference and the DateAndTimeFunctions page is a good one to bookmark.
It's also helpful to remember that it's pretty easy to play with queries with the sqlite command line utility:
sqlite> select julianday(datetime('now'));
2454788.09219907
sqlite> select datetime(julianday(datetime('now')));

The principal advantage of B+ trees over B trees is they allow you to pack in more pointers to other nodes by removing pointers to data, thus increasing the fanout and potentially decreasing the depth of the tree.
The disadvantage is that there are no early outs when you might have found a match in an internal node. But since both data structures have huge fanouts, the vast majority of your matches will be on leaf nodes anyway, making on average the B+ tree more efficient.
In Windows, you can use any combination of red green and blue on the foreground (text) and the background.
/* you can use these constants
FOREGROUND_BLUE
FOREGROUND_GREEN
FOREGROUND_RED
FOREGROUND_INTENSITY
BACKGROUND_BLUE
BACKGROUND_GREEN
BACKGROUND_RED
BACKGROUND_INTENSITY
*/
HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleTextAttribute(hConsole, FOREGROUND_BLUE | FOREGROUND_GREEN | FOREGROUND_INTENSITY);
std::cout << "I'm cyan! Who are you?" << std::endl;
In the same shell, hold ctrl key and press keys p then q
You can do this:
$("form :input").change(function() {
$(this).closest('form').data('changed', true);
});
$('#mybutton').click(function() {
if($(this).closest('form').data('changed')) {
//do something
}
});
This rigs a change
event handler to inputs in the form, if any of them change it uses .data()
to set a changed
value to true
, then we just check for that value on the click, this assumes that #mybutton
is inside the form (if not just replace $(this).closest('form')
with $('#myForm')
), but you could make it even more generic, like this:
$('.checkChangedbutton').click(function() {
if($(this).closest('form').data('changed')) {
//do something
}
});

According to jQuery this is a filter to select all form controls.
http://api.jquery.com/input-selector/
The :input selector basically selects all form controls.
Use this snippet:
$key = 'gozhi';
$sum = array_sum(array_column($array,$key));
why don't you give a try to inkscape command line, this is my bat file to convert all svg in this dir to png:
FOR %%x IN (*.svg) DO C:\Ink\App\Inkscape\inkscape.exe %%x -z --export-dpi=500 --export-area-drawing --export-png="%%~nx.png"
You can certainly #define a macro as shown below. The compiler will replace "IMAGE_SEGMENT" with its value before compilation. While you will achieve defining a global lookup for your array, it is not the same as a global variable. When the macro is expanded, it works just like inline code and so a new image is created each time. So if you are careful in where you use the macro, then you would have effectively achieved creating a global variable.
#define IMAGE_SEGMENT [[NSImage alloc] initWithContentsOfFile:@"/User/asd.jpg"];
Then use it where you need it as shown below. Each time the below code is executed, a new object is created with a new memory pointer.
imageSegment = IMAGE_SEGMENT
Use DateTime::createFromFormat like this :
$date = DateTime::createFromFormat('m/d/Y H:i:s', $input_string.' 00:00:00');
$mysql_date_string = $date->format('Y-m-d H:i:s');
You can adapt this to any input format, whereas strtotime() will assume you're using the US date format if you use /, even if you're not.
The added 00:00:00 is because createFromFormat will use the current date to fill missing data, ie : it will take the current hour:min:sec and not 00:00:00 if you don't precise it.
you can enter the jdk path required as th full path for java.exe in sql developer for oracle 11g.
I found the jdk at the following path in my system.
c:\app\sony\product\11.0.0\db_1\jdk
Take a look at the "pidstat" command, sounds like exactly what you require.
foreach(Foos foo in Enum.GetValues(typeof(Foos)))
You can create a jQuery object from a JSON object:
$.getJSON(url, data, function(json) {
$(json).each(function() {
/* YOUR CODE HERE */
});
});
The answer is in the current spec:
The section element represents a generic section of a document or application. A section, in this context, is a thematic grouping of content, typically with a heading.
Examples of sections would be chapters, the various tabbed pages in a tabbed dialog box, or the numbered sections of a thesis. A Web site's home page could be split into sections for an introduction, news items, and contact information.
Authors are encouraged to use the article element instead of the section element when it would make sense to syndicate the contents of the element.
The section element is not a generic container element. When an element is needed for styling purposes or as a convenience for scripting, authors are encouraged to use the div element instead. A general rule is that the section element is appropriate only if the element's contents would be listed explicitly in the document's outline.
Reference:
Also see:
It looks like there's been a lot of confusion about this element's purpose, but the one thing that's agreed upon is that it is not a generic wrapper, like <div>
is. It should be used for semantic purposes, and not a CSS or JavaScript hook (although it certainly can be styled or "scripted").
A better example, from my understanding, might look something like this:
<div id="content">
<article>
<h2>How to use the section tag</h2>
<section id="disclaimer">
<h3>Disclaimer</h3>
<p>Don't take my word for it...</p>
</section>
<section id="examples">
<h3>Examples</h3>
<p>But here's how I would do it...</p>
</section>
<section id="closing_notes">
<h3>Closing Notes</h3>
<p>Well that was fun. I wonder if the spec will change next week?</p>
</section>
</article>
</div>
Note that <div>
, being completely non-semantic, can be used anywhere in the document that the HTML spec allows it, but is not necessary.
You can change the labels' text by adorning the property with the DisplayName
attribute.
[DisplayName("Someking Status")]
public string SomekingStatus { get; set; }
Or, you could write the raw HTML explicitly:
<label for="SomekingStatus" class="control-label">Someking Status</label>
A big reason it is handy, is when you need to refresh the data in a multi-million row table, but don't want to rebuild it. "Delete *" would take forever, whereas the perfomance impact of Truncate would be negligible.
As root on CentOS 7:
systemctl start memcached
systemctl stop memcached
systemctl restart memcached
To tell the service to start at reboot (ex chkconfig):
systemctl enable memcached
To tell the service to not start at reboot:
systemctl disable memcached
You need to set storyboard Id from storyboard identity inspector
AddTaskViewController *add=[self.storyboard instantiateViewControllerWithIdentifier:@"storyboard_id"];
[self presentViewController:add animated:YES completion:nil];
You should consider have other php files included if you're going to derive a website from it. Instead of doing all the css/etc in that file, you can do
<head>
<?php include_once('C:\Users\George\Documents\HTML\style.css'); ?>
<title>Title</title>
</hea>
Then you can have a separate CSS file that is just being pulled into your php file. It provides some "neater" coding.
I haven’t actually done anything with font-face
, so take this with a pinch of salt, but I don’t think there’s any way for the browser to definitively tell if a given web font installed on a user’s machine or not.
The user could, for example, have a different font with the same name installed on their machine. The only way to definitively tell would be to compare the font files to see if they’re identical. And the browser couldn’t do that without downloading your web font first.
Does Firefox download the font when you actually use it in a font
declaration? (e.g. h1 { font: 'DejaVu Serif';
)?
For Unit Tests, the System variable is not instantiated yet when I do "mvn clean install" because there is no server running the application. So in order to set the System properties, I need to do it in pom.xml. Like so:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.21.0</version>
<configuration>
<systemPropertyVariables>
<propertyName>propertyValue</propertyName>
<MY_ENV_VAR>newValue</MY_ENV_VAR>
<ENV_TARGET>olqa</ENV_TARGET>
<buildDirectory>${project.build.directory}</buildDirectory>
</systemPropertyVariables>
</configuration>
</plugin>
According to updated Apple document (check my answer date):
"... When using the HTTP/2 provider API, maximum payload size is 4096 bytes. Using the legacy binary interface, maximum payload size is 2048 bytes. Apple Push Notification service (APNs) refuses any notification that exceeds the maximum size."
If the mouse over for all over the component is your option, you can directly is @hostListener
to handle the events to perform the mouse over al below.
import {HostListener} from '@angular/core';
@HostListener('mouseenter') onMouseEnter() {
this.hover = true;
this.elementRef.nativeElement.addClass = 'edit';
}
@HostListener('mouseleave') onMouseLeave() {
this.hover = false;
this.elementRef.nativeElement.addClass = 'un-edit';
}
Its available in @angular/core
. I tested it in angular 4.x.x
As Opera is powered by Blink since Version 15.0 -webkit-font-smoothing: antialiased
does also work on Opera.
Firefox has finally added a property to enable grayscaled antialiasing. After a long discussion it will be available in Version 25 with another syntax, which points out that this property only works on OS X.
-moz-osx-font-smoothing: grayscale;
This should fix blurry icon fonts or light text on dark backgrounds.
.font-smoothing {
-webkit-font-smoothing: antialiased;
-moz-osx-font-smoothing: grayscale;
}
You may read my post about font rendering on OSX which includes a Sass mixin to handle both properties.
Put this on an event
$(function(){
$('.package').click(function(){
var content = $('.container').html();
$(this).html(content);
});
});
You can't move the mouse pointer using javascript, and thus for obvious security reasons. The best way to achieve this effect would be to actually place the control under the mouse pointer.
Before running your app, you can do this in console,
export NODE_ENV=production
Or if you are in windows you could try this:
SET NODE_ENV=production
for PowerShell:
$env:NODE_ENV="production"
or you can run your app like this:
NODE_ENV=production node app.js
You can also set it in your js file:
process.env.NODE_ENV = 'production';
But I don't suggest to do it in your runtime file, since it's not easy to open up VIM in your server and change it to production. You can make a config.json file in your directory and everytime your app runs, it reads from it and sets the configuration.
since you are using jquery
library, i would advise you utilize the reset()
method.
Firstly, add an id attribute to the form tag
<form id='myForm'>
Then on completion, clear your input fields as:
$('#myForm')[0].reset();
