The error is also caused by quirky handling of quotes and single qutoes. To include single quotes inside the query, use doubled single quotes.
This won't work
select dbms_xmlgen.getxml("Select ....") XML from dual;
or this either
select dbms_xmlgen.getxml('Select .. where something='red'..') XML from dual;
but this DOES work
select dbms_xmlgen.getxml('Select .. where something=''red''..') XML from dual;
Pass re.IGNORECASE

Simple and with little changes. And also hide load more when entire list is loaded.
jsFiddle here.
$(document).ready(function () {
// Load the first 3 list items from another HTML file
//$('#myList').load('externalList.html li:lt(3)');
$('#myList li:lt(3)').show();
$('#showLess').hide();
var items = 25;
var shown = 3;
$('#loadMore').click(function () {
$('#showLess').show();
shown = $('#myList li:visible').size()+5;
if(shown< items) {$('#myList li:lt('+shown+')').show();}
else {$('#myList li:lt('+items+')').show();
$('#loadMore').hide();
}
});
$('#showLess').click(function () {
$('#myList li').not(':lt(3)').hide();
});
});
Did the same thing for another quetion here

If you like to get a list of all values of checked checkboxes (e.g. to send them as a list in one AJAX call to the server), you could get that list with:
var list = $("input[name='bla[]']:checked").map(function () {
return this.value;
}).get();
I would use enums as a useful mapping instrument, avoiding multiple if-else
provided that some methods are implemented.
public enum Mapping {
ONE("1"),
TWO("2");
private String label;
private Mapping(String label){
this.label = label;
}
public static Mapping by(String label) {
for(Mapping m: values() {
if(m.label.equals(label)) return m;
}
return null;
}
}
So the method by(String label)
allows you to get the Enumerated value by non-enumerated. Further, one can invent mapping between 2 enums. Could also try '1 to many' or 'many to many' in addition to 'one to one' default relation
In the end, enum
is a Java class. So you can have main
method inside it, which might be useful when needing to do some mapping operations on args
right away.

Tested and worked in IE, Firefox, Chrome, Safari and Opera. I did not test IE6. The outer text-align is needed for IE. Other browsers (and IE9?) will work when you give the DIV margin (left and right) value of auto. Margin "0 auto" is a shorthand for margin "0 auto 0 auto" (top right bottom left).
Note: the text is also centered inside the inner DIV, if you want it to remain on the left side just specify text-align: left; for the inner DIV.
Edit: IE 6, 7, 8 and 9 running on the Standards Mode will work with margins set to auto.
To sign an assembly with a strong name using attributes
Open AssemblyInfo.cs
(in $(SolutionDir)\Properties
)
the AssemblyKeyFileAttribute
or the AssemblyKeyNameAttribute
, specifying the name of the file or container that contains the key pair to use when signing the assembly with a strong name.
add the following code:
[assembly:AssemblyKeyFileAttribute("keyfile.snk")]
WinSCp now supports S3 protocol
First, make sure your AWS user with S3 access permissions has an “Access key ID” created. You also have to know the “Secret access key”. Access keys are created and managed on Users page of IAM Management Console.
Make sure New site node is selected.
On the New site node, select Amazon S3 protocol.
Enter your AWS user Access key ID and Secret access key
Save your site settings using the Save button.
Login using the Login button.
A (partial) practical work-around is to put things into a throw-away function.
Pasting
x = 1
x += 1
print(x)
results in
>>> x = 1
x += 1
print(x)
File "<stdin>", line 1
x += 1
print(x)
^
SyntaxError: multiple statements found while compiling a single statement
>>>
However, pasting
def abc():
x = 1
x += 1
print(x)
works:
>>> def abc():
x = 1
x += 1
print(x)
>>> abc()
2
>>>
Of course, this is OK for a quick one-off, won't work for everything you might want to do, etc. But then, going to ipython
/ jupyter qtconsole
is probably the next simplest option.
I had the same problem and solved it with:
Code:
$.fn.nextNode = function(){
var contents = $(this).parent().contents();
return contents.get(contents.index(this)+1);
}
Usage:
$('#my_id').nextNode();
Is like next()
but also returns the text nodes.
I also got this error .I was using Text inside body after changing to XML(text/xml) , got result as expected.
If your request is XML Request use XML(text/xml).
If your request is JSON Request use JSON(application/json)
I suspect the path is not correct. As mentioned by user7412219 ubuntu and windows deal with path differently. Try to put the image in the same folder as your Notebook and use:
![alt text](Isolated.png "Title")
On windows the desktop should be at: C:\Users\jzhang\Desktop
MySQL will also report "Column count doesn't match value count at row 1" if you try to insert multiple rows without delimiting the row sets in the VALUES section with parentheses, like so:
INSERT INTO `receiving_table`
(id,
first_name,
last_name)
VALUES
(1002,'Charles','Babbage'),
(1003,'George', 'Boole'),
(1001,'Donald','Chamberlin'),
(1004,'Alan','Turing'),
(1005,'My','Widenius');
The easyest way
In your html:
<a id="foo" disabled="true">xxxxx<a>
In your js:
$('#foo').attr("disabled", false);
If you use it as attribute works perfectly
You can get some inspiration by reading an entrypoint.sh
script written by the contributors from MySQL that checks whether the specified variables were set.
As the script shows, you can pipe them with -a
, e.g.:
if [ -z "$MYSQL_ROOT_PASSWORD" -a -z "$MYSQL_ALLOW_EMPTY_PASSWORD" -a -z "$MYSQL_RANDOM_ROOT_PASSWORD" ]; then
...
fi
Probably you haven't injected $http
service to your controller. There are several ways of doing that.
Please read this reference about DI. Then it gets very simple:
function MyController($scope, $http) {
// ... your code
}
If you do not need to add a border on columns, you can also simply add a transparent border on them:
[class*="col-"] {
background-clip: padding-box;
border: 10px solid transparent;
}
This avoids using any sql
using (var context = new MyDbContext())
{
var itemsToDelete = context.Set<MyTable>();
context.MyTables.RemoveRange(itemsToDelete);
context.SaveChanges();
}
You can do this in the storyboard / xib editor as well. Just set Seperator to none.
Just delete module-info.java at your Project Explorer tab.
if you provide a bad path or a broken link, if the compiler cannot find the image, the picture box would display an X icon on its body.
PictureBox picture = new PictureBox
{
Name = "pictureBox",
Size = new Size(100, 50),
Location = new Point(14, 17),
Image = Image.FromFile(@"c:\Images\test.jpg"),
SizeMode = PictureBoxSizeMode.CenterImage
};
p.Controls.Add(picture);
OR
PictureBox picture = new PictureBox
{
Name = "pictureBox",
Size = new Size(100, 50),
Location = new Point(14, 17),
ImageLocation = @"c:\Images\test.jpg",
SizeMode = PictureBoxSizeMode.CenterImage
};
p.Controls.Add(picture);
i'm not sure where you put images in your folder structure but you can find the path as bellow
picture.ImageLocation = Path.Combine(System.Windows.Forms.Application.StartupPath, "Resources\Images\1.jpg");
Other than returning an array or an object as others have recommended, you can also use a collector function (similar to the one found in The Little Schemer):
function a(collector){
collector(12,13);
}
var x,y;
a(function(a,b){
x=a;
y=b;
});
I made a jsperf test to see which one of the three methods is faster. Array is fastest and collector is slowest.
A Protocol?
I found this, it appears to be a local setting for a computer...
Make sure you are using ssh for your repository also

The answer I want to give is "use collections.ChainMap", but I just discovered that it was only added in Python 3.3: https://docs.python.org/3.3/library/collections.html#chainmap-objects
You can try to crib the class from the 3.3 source though: http://hg.python.org/cpython/file/3.3/Lib/collections/init.py#l763
Here is a less feature-full Python 2.x compatible version (same author): http://code.activestate.com/recipes/305268-chained-map-lookups/
Instead of expanding/overwriting one dictionary with another using dict.merge, or creating an additional copy merging both, you create a lookup chain that searches both in order. Because it doesn't duplicate the mappings it wraps ChainMap uses very little memory, and sees later modifications to any sub-mapping. Because order matters you can also use the chain to layer defaults (i.e. user prefs > config > env).

Efran Cobisi's suggestion of using an Auto Mapper is a good one. I have used Auto Mapper for a while and it worked well, until I found the much faster alternative, Mapster.
Given a large list or IEnumerable, Mapster outperforms Auto Mapper. I found a benchmark somewhere that showed Mapster being 6 times as fast, but I could not find it again. You could look it up and then, if it is suits you, use Mapster.

Chrome on Android makes it possible to use the Chrome developer tools on the desktop to inspect the HTML that was loaded from the Chrome application on the Android device.
See: https://developers.google.com/chrome-developer-tools/docs/remote-debugging
There is no .length property in C. The .length property can only be applied to arrays in object oriented programming (OOP) languages. The .length property is inherited from the object class; the class all other classes & objects inherit from in an OOP language. Also, one would use .length-1 to return the number of the last index in an array; using just the .length will return the total length of the array.
I would suggest something like this:
int index;
int jdex;
for( index = 0; index < (sizeof( my_array ) / sizeof( my_array[0] )); index++){
for( jdex = 0; jdex < (sizeof( my_array ) / sizeof( my_array[0] )); jdex++){
printf( "%d", my_array[index][jdex] );
printf( "\n" );
}
}
The line (sizeof( my_array ) / sizeof( my_array[0] )) will give you the size of the array in question. The sizeof property will return the length in bytes, so one must divide the total size of the array in bytes by how many bytes make up each element, each element takes up 4 bytes because each element is of type int, respectively. The array is of total size 16 bytes and each element is of 4 bytes so 16/4 yields 4 the total number of elements in your array because indexing starts at 0 and not 1.
I got in trouble at work one time. I was accused of using "magic numbers" in array declarations.
Like this:
int Marylyn[256], Ann[1024];
The company policy was to avoid these magic numbers because, it was explained to me, that these numbers were not portable; that they impeded easy maintenance. I argued that when I am reading the code, I want to know exactly how big the array is. I lost the argument and so, on a Friday afternoon I replaced the offending "magic numbers" with #defines, like this:
#define TWO_FIFTY_SIX 256
#define TEN_TWENTY_FOUR 1024
int Marylyn[TWO_FIFTY_SIX], Ann[TEN_TWENTY_FOUR];
On the following Monday afternoon I was called in and accused of having passive defiant tendencies.
We had today a problem like this, but we didn't wanted to change the HTML. So we used mouseenter event to achieve that
var doThingsOnClick = function() {
// your click function here
};
$(document).on({
'mouseenter': function () {
$(this).removeAttr('disabled').bind('click', doThingsOnClick);
},
'mouseleave': function () {
$(this).unbind('click', doThingsOnClick).attr('disabled', 'disabled');
},
}, 'input.disabled');
With inspiration from the Bob's answer, these extensions also support null value conversion and all primitive conversion back and fourth.
public static class ConversionExtensions
{
public static object Convert(this object value, Type t)
{
Type underlyingType = Nullable.GetUnderlyingType(t);
if (underlyingType != null && value == null)
{
return null;
}
Type basetype = underlyingType == null ? t : underlyingType;
return System.Convert.ChangeType(value, basetype);
}
public static T Convert<T>(this object value)
{
return (T)value.Convert(typeof(T));
}
}
Examples
string stringValue = null;
int? intResult = stringValue.Convert<int?>();
int? intValue = null;
var strResult = intValue.Convert<string>();
There's a much easier way to do this, using iconv
- from the user notes, this seems to be what you want to do: characters transliteration
// PHP.net User notes
<?php
$string = "?ABBASABAD";
echo iconv('UTF-8', 'ISO-8859-1//TRANSLIT', $string);
// output: [nothing, and you get a notice]
echo iconv('UTF-8', 'ISO-8859-1//IGNORE', $string);
// output: ABBSBD
echo iconv('UTF-8', 'ISO-8859-1//TRANSLIT//IGNORE', $string);
// output: ABBASABAD
// Yay! That's what I wanted!
?>
Be very conscientious with your character encodings, so you are keeping the same encoding at all stages in the process - front end, form submission, encoding of the source files. Default encoding in PHP and in forms is ISO-8859-1, before PHP 5.4 where it changed to be UTF8 (finally!).
There's a couple of functions you can play around with for ideas. First is from CakePHP's inflector class, called slug
:
public static function slug($string, $replacement = '_') {
$quotedReplacement = preg_quote($replacement, '/');
$merge = array(
'/[^\s\p{Ll}\p{Lm}\p{Lo}\p{Lt}\p{Lu}\p{Nd}]/mu' => ' ',
'/\\s+/' => $replacement,
sprintf('/^[%s]+|[%s]+$/', $quotedReplacement, $quotedReplacement) => '',
);
$map = self::$_transliteration + $merge;
return preg_replace(array_keys($map), array_values($map), $string);
}
It depends on a self::$_transliteration
array which is similar to what you were doing in your question - you can see the source for inflector on github.
Another is a function I use personally, which comes from here.
function slugify($text,$strict = false) {
$text = html_entity_decode($text, ENT_QUOTES, 'UTF-8');
// replace non letter or digits by -
$text = preg_replace('~[^\\pL\d.]+~u', '-', $text);
// trim
$text = trim($text, '-');
setlocale(LC_CTYPE, 'en_GB.utf8');
// transliterate
if (function_exists('iconv')) {
$text = iconv('utf-8', 'us-ascii//TRANSLIT', $text);
}
// lowercase
$text = strtolower($text);
// remove unwanted characters
$text = preg_replace('~[^-\w.]+~', '', $text);
if (empty($text)) {
return 'empty_$';
}
if ($strict) {
$text = str_replace(".", "_", $text);
}
return $text;
}
What those functions do is transliterate and create 'slugs' from arbitrary text input, which is a very very useful thing to have in your toolchest when making web apps. Hope this helps!
The main idea is
Stash the changes in a dirty working directory away
So Basicallly Stash command keep your some changes that you don't need them or want them at the moment; but you may need them.
Use git stash when you want to record the current state of the working directory and the index, but want to go back to a clean working directory. The command saves your local modifications away and reverts the working directory to match the HEAD commit.
One way is that In case of Session Expire, in every action you have to check its session and if it is null then redirect to Login page.
But this is very hectic method
To over come this you need to create your own ActionFilterAttribute
which will do this, you just need to add this attribute in every action method.
Here is the Class which overrides ActionFilterAttribute.
public class SessionExpireFilterAttribute : ActionFilterAttribute
{
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
HttpContext ctx = HttpContext.Current;
// check if session is supported
CurrentCustomer objCurrentCustomer = new CurrentCustomer();
objCurrentCustomer = ((CurrentCustomer)SessionStore.GetSessionValue(SessionStore.Customer));
if (objCurrentCustomer == null)
{
// check if a new session id was generated
filterContext.Result = new RedirectResult("~/Users/Login");
return;
}
base.OnActionExecuting(filterContext);
}
}
Then in action just add this attribute like so:
[SessionExpire]
public ActionResult Index()
{
return Index();
}
This will do you work.
I was getting similar errors, turns out that the dataset had blank values which python could not convert to integer.
For some people, the accepted answer is not working, I found this other answer and it is working for me: How can I pass a parameter to a setTimeout() callback?
var hello = "Hello World";
setTimeout(alert, 1000, hello);
'hello' is the parameter being passed, you can pass all the parameters after the timeout time. Thanks to @Fabio Phms for the answer.
Choose Database | Set Datasource Location... Select the database node (yellow-ish cylinder) of the current connection, then select the database node of the desired connection (you may need to authenticate), then click Update.
You will need to do this for the 'Subreports' nodes as well.
FYI, you can also do individual tables by selecting each individually, then choosing Update.
Use defaultValue
to preselect the values for Select.
<Select defaultValue={[{ value: category.published, label: 'Publish' }]} options={statusOptions} onChange={handleStatusChange} />

For Email Address validation try this simple and easy code.

if (!Patterns.EMAIL_ADDRESS.matcher(email).matches())
{
inputEmail.setError("Enter Valid Email Address");
inputEmail.requestFocus();
}
To answer the underlying question of how to use a CASE expression in the WHERE clause:
First remember that the value of a CASE expression has to have a normal data type value, not a boolean value. It has to be a varchar, or an int, or something. It's the same reason you can't say SELECT Name, 76 = Age FROM [...]
and expect to get 'Frank', FALSE
in the result set.
Additionally, all expressions in a WHERE clause need to have a boolean value. They can't have a value of a varchar or an int. You can't say WHERE Name;
or WHERE 'Frank';
. You have to use a comparison operator to make it a boolean expression, so WHERE Name = 'Frank';
That means that the CASE expression must be on one side of a boolean expression. You have to compare the CASE expression to something. It can't stand by itself!
Here:
WHERE
DateDropped = 0
AND CASE
WHEN @JobsOnHold = 1 AND DateAppr >= 0 THEN 'True'
WHEN DateAppr != 0 THEN 'True'
ELSE 'False'
END = 'True'
Notice how in the end the CASE expression on the left will turn the boolean expression into either 'True' = 'True'
or 'False' = 'True'
.
Note that there's nothing special about 'False'
and 'True'
. You can use 0
and 1
if you'd rather, too.
You can typically rewrite the CASE expression into boolean expressions we're more familiar with, and that's generally better for performance. However, sometimes is easier or more maintainable to use an existing expression than it is to convert the logic.
I found that the safest and reliable way to do it is to use FileReader()
.

I'm not sure about your first code sample where you use WebClient.UploadValues, it's not really enough to go on, could you paste more of your surrounding code? Regarding your WebRequest code, there are two things at play here:
You're only requesting the headers of the response**, you never read the body of the response by opening and reading (to its end) the ResponseStream. Because of this, the WebRequest client helpfully leaves the connection open, expecting you to request the body at any moment. Until you either read the response body to completion (which will automatically close the stream for you), clean up and close the stream (or the WebRequest instance) or wait for the GC to do its thing, your connection will remain open.
You have a default maximum amount of active connections to the same host of 2. This means you use up your first two connections and then never dispose of them so your client isn't given the chance to complete the next request before it reaches its timeout (which is milliseconds, btw, so you've set it to 0.2 seconds - the default should be fine).
If you don't want the body of the response (or you've just uploaded or POSTed something and aren't expecting a response), simply close the stream, or the client, which will close the stream for you.
The easiest way to fix this is to make sure you use using blocks on disposable objects:
for (int i = 0; i < ops1; i++)
{
Uri myUri = new Uri(site);
WebRequest myWebRequest = WebRequest.Create(myUri);
//myWebRequest.Timeout = 200;
using (WebResponse myWebResponse = myWebRequest.GetResponse())
{
// Do what you want with myWebResponse.Headers.
} // Your response will be disposed of here
}
Another solution is to allow 200 concurrent connections to the same host. However, unless you're planning to multi-thread this operation so you'd need multiple, concurrent connections, this won't really help you:
ServicePointManager.DefaultConnectionLimit = 200;
When you're getting timeouts within code, the best thing to do is try to recreate that timeout outside of your code. If you can't, the problem probably lies with your code. I usually use cURL for that, or just a web browser if it's a simple GET request.
** In reality, you're actually requesting the first chunk of data from the response, which contains the HTTP headers, and also the start of the body. This is why it's possible to read HTTP header info (such as Content-Encoding, Set-Cookie etc) before reading from the output stream. As you read the stream, further data is retrieved from the server. WebRequest's connection to the server is kept open until you reach the end of this stream (effectively closing it as it's not seekable), manually close it yourself or it is disposed of. There's more about this here.

Use something like this
$.getJSON("../../data/file.json", function(json) {
console.log(json); // this will show the info in firebug console
alert(json);
});
If you run into this problem after having $GOPATH
set up, it may be because you're running it with an unsupported shell. I was using fish
and it did not work, launching it with bash
worked fine.
WITHOUT USING JAVASCRIPT
Just add #t=[(start_time), (end_time)]
to the end of your media URL. The only setback (if you want to see it that way) is you'll need to know how long your video is to indicate the end time.
Example:
<video>
<source src="splash.mp4#t=10,20" type="video/mp4">
</video>
Notes: Not supported in IE
If someone need a solution without an external javascript libraries you could use this example. A group of checkboxes allowing 0..1 values. You may click on the checkbox component or associated label text.
<input id="mygroup1" name="mygroup" type="checkbox" value="1" onclick="toggleRadioCheckbox(this)" /> <label for="mygroup1">Yes</label>
<input id="mygroup0" name="mygroup" type="checkbox" value="0" onclick="toggleRadioCheckbox(this)" /> <label for="mygroup0">No</label>
- - - - - - - -
function toggleRadioCheckbox(sender) {
// RadioCheckbox: 0..1 enabled in a group
if (!sender.checked) return;
var fields = document.getElementsByName(sender.name);
for(var idx=0; idx<fields.length; idx++) {
var field = fields[idx];
if (field.checked && field!=sender)
field.checked=false;
}
}
string[] lines = File.ReadAllLines(txtProxyListPath.Text);
// No need for the list
// List<string> list_lines = new List<string>(lines);
Parallel.ForEach(lines, line =>
{
//My Stuff
});
This will cause the lines to be parsed in parallel, within the loop. If you want a more detailed, less "reference oriented" introduction to the Parallel class, I wrote a series on the TPL which includes a section on Parallel.ForEach.
Andrew White's answer is sufficient to get you moving. Here's a step-by-step for beginners.
A simple get started:
Create test.cpp: (This will be built and run to verify you got things set up right.)
#include <X11/Xlib.h>
#include <unistd.h>
main()
{
// Open a display.
Display *d = XOpenDisplay(0);
if ( d )
{
// Create the window
Window w = XCreateWindow(d, DefaultRootWindow(d), 0, 0, 200,
100, 0, CopyFromParent, CopyFromParent,
CopyFromParent, 0, 0);
// Show the window
XMapWindow(d, w);
XFlush(d);
// Sleep long enough to see the window.
sleep(10);
}
return 0;
}
Try: g++ test.cpp -lX11
If it builds to a.out
, try running it.
If you see a simple window drawn, you have the necessary libraries, and some other root problem is afoot.
If your response is:
test.cpp:1:22: fatal error: X11/Xlib.h: No such file or directory
compilation terminated.
you need to install X11 development libraries.
sudo apt-get install libx11-dev
Retry g++ test.cpp -lX11
If it works, you're golden.
Tested using a fresh install of libX11-dev_2%3a1.5.0-1_i386.deb
split doesn't work that way in groovy. you have to use tokenize...
See the docs:
As a specific instance of one of the two hard things in computing, it’s interesting to see how the answers to this question have changed since this question was originally posted. Thankfully, the powers that be have brought order to the chaos:
In February this year (2017), the W3C published the Standards Track RFC 8081: The "font" Top-Level Media Type which greatly simplifies the appropriate media types for font files:
This memo serves to register and document the "font" top-level media type, under which subtypes for representation formats for fonts may be registered. This document also serves as a registration application for a set of intended subtypes, which are representative of some existing subtypes already in use, and currently registered under the "application" tree by their separate registrations.
It’s quite a readable document and it describes the historical context (lack of “a registration of formats for font”) which gave rise to the confusing mix of media types and sub-types. With the (relatively) recent rise in popularity of downloadable web fonts, the W3C recognised the need for an “intuitive top-level font type”. What they came up with is … font
.
Accordingly, the IANA have since updated their official list of Media types with the font
media type and all its sub-types that they currently recognise:
collection font/collection
otf font/otf
sfnt font/sfnt
ttf font/ttf
woff font/woff
woff2 font/woff2
Here’s hoping this is the last answer this question needs.
To plot just a selection of your columns you can select the columns of interest by passing a list to the subscript operator:
ax = df[['V1','V2']].plot(kind='bar', title ="V comp", figsize=(15, 10), legend=True, fontsize=12)
What you tried was df['V1','V2']
this will raise a KeyError
as correctly no column exists with that label, although it looks funny at first you have to consider that your are passing a list hence the double square brackets [[]]
.
import matplotlib.pyplot as plt
ax = df[['V1','V2']].plot(kind='bar', title ="V comp", figsize=(15, 10), legend=True, fontsize=12)
ax.set_xlabel("Hour", fontsize=12)
ax.set_ylabel("V", fontsize=12)
plt.show()
Use Regex object like this
var regex = new RegExp('"', 'g');
str = str.replace(regex, '\'');
It will replace all occurrence of "
into '
.
You should use overflow:hidden;
or scroll
or with php you could short the long words...
//Parent/Children[@ Attribute='value']/@Attribute
This is the case which can be used where element is having 2 attribute and we can get the one attribute with the help of another one.
this code work fine with IE, Firefox, Opera and Chrome:
$(window).bind('wheel mousewheel', function(event) {
if (event.originalEvent.deltaY >= 0) {
console.log('Scroll down');
}
else {
console.log('Scroll up');
}
});
'wheel mousewheel' and the property deltaY must be use in bind() function.
Remember : You're user must update their system and browsers for security reasons. In 2018, the excuses of "I have IE 7" is a nonsense. We must educate users.
Have a good day :)
May be this way:
<?php
if($_SERVER['REQUEST_METHOD']=="POST") {
echo 'asdasda';
}
?>
<form method="post">
<button type="submit" id="okButton">Order now</button>
</form>
Thanks guys :-) I used the below because I only cared about those two columns and not so much about the rest. Worked great
select email, login_id from table
group by email, login_id
having COUNT(email) > 1
If you're using pure JS you can simply do it like:
var input = document.getElementById('myInput');
if(input.value.length == 0)
input.value = "Empty";
Here's a demo: http://jsfiddle.net/nYtm8/
select * from left table where key field not in (select key field from right table)
You can try Salar.Bois serializer which has a decent performance. Its focus is on payload size but it also offers good performance.
There are benchmarks in the Github page if you wish to see and compare the results by yourself.
I got this exception while coping a object(variable) Matrix Array into Excel sheet. The solution to this is, Matrix array Index(i,j) must start from (0,0) whereas Excel sheet should start with Matrix Array index (i,j) from (1,1) .
I hope you this concept.
You need to use a textarea to get multiline handling.
<textarea name="Text1" cols="40" rows="5"></textarea>
_x000D_
This works for me:
var object = { a: 4, b: 0.5 , c: 0.35, d: 5 };
// Take all value from the object into list
var valueList = $.map(object,function(v){
return v;
});
var max = valueList.reduce(function(a, b) { return Math.max(a, b); });
var min = valueList.reduce(function(a, b) { return Math.min(a, b); });
I have removed JAVA_HOME variable and kept only path and classpath variables by pointing them to jdk and jre respectively. It worked for me.
Some IDEs highlight the code in heredoc strings automatically - which makes using heredoc for XML or HTML visually appealing.
I personally like it for longer parts of i.e. XML since I don't have to care about quoting quote characters and can simply paste the XML.
I spent a lot of time looking for a solution to this problem too. Here's what i've found thus far:
If you want your users to be able to click on a button and copy some text, you may have to use Flash.
If you want your users to press Ctrl+C anywhere on the page, but always copy xyz to the clipboard, I wrote an all-JS solution in YUI3 (although it could easily be ported to other frameworks, or raw JS if you're feeling particularly self-loathing).
It involves creating a textbox off the screen which gets highlighted as soon as the user hits Ctrl/CMD. When they hit 'C' shortly after, they copy the hidden text. If they hit 'V', they get redirected to a container (of your choice) before the paste event fires.
This method can work well, because while you listen for the Ctrl/CMD keydown anywhere in the body, the 'A', 'C' or 'V' keydown listeners only attach to the hidden text box (and not the whole body). It also doesn't have to break the users expectations - you only get redirected to the hidden box if you had nothing selected to copy anyway!
Here's what i've got working on my site, but check http://at.cg/js/clipboard.js for updates if there are any:
YUI.add('clipboard', function(Y) {
// Change this to the id of the text area you would like to always paste in to:
pasteBox = Y.one('#pasteDIV');
// Make a hidden textbox somewhere off the page.
Y.one('body').append('<input id="copyBox" type="text" name="result" style="position:fixed; top:-20%;" onkeyup="pasteBox.focus()">');
copyBox = Y.one('#copyBox');
// Key bindings for Ctrl+A, Ctrl+C, Ctrl+V, etc:
// Catch Ctrl/Window/Apple keydown anywhere on the page.
Y.on('key', function(e) {
copyData();
// Uncomment below alert and remove keyCodes after 'down:' to figure out keyCodes for other buttons.
// alert(e.keyCode);
// }, 'body', 'down:', Y);
}, 'body', 'down:91,224,17', Y);
// Catch V - BUT ONLY WHEN PRESSED IN THE copyBox!!!
Y.on('key', function(e) {
// Oh no! The user wants to paste, but their about to paste into the hidden #copyBox!!
// Luckily, pastes happen on keyPress (which is why if you hold down the V you get lots of pastes), and we caught the V on keyDown (before keyPress).
// Thus, if we're quick, we can redirect the user to the right box and they can unload their paste into the appropriate container. phew.
pasteBox.select();
}, '#copyBox', 'down:86', Y);
// Catch A - BUT ONLY WHEN PRESSED IN THE copyBox!!!
Y.on('key', function(e) {
// User wants to select all - but he/she is in the hidden #copyBox! That wont do.. select the pasteBox instead (which is probably where they wanted to be).
pasteBox.select();
}, '#copyBox', 'down:65', Y);
// What to do when keybindings are fired:
// User has pressed Ctrl/Meta, and is probably about to press A,C or V. If they've got nothing selected, or have selected what you want them to copy, redirect to the hidden copyBox!
function copyData() {
var txt = '';
// props to Sabarinathan Arthanari for sharing with the world how to get the selected text on a page, cheers mate!
if (window.getSelection) { txt = window.getSelection(); }
else if (document.getSelection) { txt = document.getSelection(); }
else if (document.selection) { txt = document.selection.createRange().text; }
else alert('Something went wrong and I have no idea why - please contact me with your browser type (Firefox, Safari, etc) and what you tried to copy and I will fix this immediately!');
// If the user has nothing selected after pressing Ctrl/Meta, they might want to copy what you want them to copy.
if(txt=='') {
copyBox.select();
}
// They also might have manually selected what you wanted them to copy! How unnecessary! Maybe now is the time to tell them how silly they are..?!
else if (txt == copyBox.get('value')) {
alert('This site uses advanced copy/paste technology, possibly from the future.\n \nYou do not need to select things manually - just press Ctrl+C! \n \n(Ctrl+V will always paste to the main box too.)');
copyBox.select();
} else {
// They also might have selected something completely different! If so, let them. It's only fair.
}
}
});
Hope someone else finds this useful :]
Adding the answer for Windows User for the latest postgres version (>10),
Go to your postgres installation location, and search for pg_hba.conf
,
you will find it in ..\postgres\data\pg_hba.conf
Open that file with notepad, find this line,
# TYPE DATABASE USER ADDRESS METHOD
# IPv4 local connections:
host all all 127.0.0.1/32 md5
# IPv6 local connections:
host all all ::1/128 md5
#..
Change the method from md5 to trust,
# TYPE DATABASE USER ADDRESS METHOD
# IPv4 local connections:
host all all 127.0.0.1/32 trust
# IPv6 local connections:
host all all ::1/128 trust
# ...
Now go to your SQL Shell(PSQL) and leave everything blank,
Server [localhost]:
Database [postgres]:
Port [8000]:
Username [postgres]:
It will not ask for password this time, and you will be logged in,
Now run this line,
ALTER USER yourusername WITH SUPERUSER
Now you can leave the shell with \q
Again go to the file pg_hba.conf and change METHOD from trust to md5 again, and save it.
Now login with your new user and password and you can check \du for its attributes.
I wrote a program with wpf
and used Database for showing images and this is my code:
SqlConnection con = new SqlConnection(@"Data Source=HITMAN-PC\MYSQL;
Initial Catalog=Payam;
Integrated Security=True");
SqlDataAdapter da = new SqlDataAdapter("select * from news", con);
DataTable dt = new DataTable();
da.Fill(dt);
string adress = dt.Rows[i]["ImgLink"].ToString();
ImageSource imgsr = new BitmapImage(new Uri(adress));
PnlImg.Source = imgsr;
To change the text AB
into A \r B
in a table cell, put this into the cell position: \makecell{A \\ B}
.
Before doing that, you also need to include package makecell
.
If you're using PostgreSQL 8 or above, you may need to modify the listen_addresses
setting in /etc/postgresql/8.4/main/postgresql.conf
.
Try adding the line:
listen_addresses = *
which will tell PostgreSQL to listen for connections on all network interfaces.
If not explicitly set, this setting defaults to localhost
which means it will only accept connections from the same machine.
If you want programmatic setText without add string to string.xml
see its hexadecimal code here:
http://fortawesome.github.io/Font-Awesome/cheatsheet/
replace  to 0xf066
Typeface typeface = Typeface.createFromAsset(getAssets(), "fontawesome-webfont.ttf");
textView.setTypeface(typeface);
textView.setText(new String(new char[]{0xf006 }));
I am a beginner so here is a beginners answer. The if in the for loop gives i which can then be used however needed such as Numbers[i] in another vector. Most is fluff for examples sake, the for/if really says it all.
int main(){
vector<string>names{"Sara", "Harold", "Frank", "Taylor", "Sasha", "Seymore"};
string req_name;
cout<<"Enter search name: "<<'\n';
cin>>req_name;
for(int i=0; i<=names.size()-1; ++i) {
if(names[i]==req_name){
cout<<"The index number for "<<req_name<<" is "<<i<<'\n';
return 0;
}
else if(names[i]!=req_name && i==names.size()-1) {
cout<<"That name is not an element in this vector"<<'\n';
} else {
continue;
}
}
Yes, you need to make getInstance()
synchronized. If it's not there might arise a situation where multiple instances of the class can be made.
Consider the case where you have two threads that call getInstance()
at the same time. Now imagine T1 executes just past the instance == null
check, and then T2 runs. At this point in time the instance is not created or set, so T2 will pass the check and create the instance. Now imagine that execution switches back to T1. Now the singleton is created, but T1 has already done the check! It will proceed to make the object again! Making getInstance()
synchronized prevents this problem.
There a few ways to make singletons thread-safe, but making getInstance()
synchronized is probably the simplest.
the simplest for me
android:numeric="integer"
although this also more customize
android:digits="0123456789"
It refers to the instance of the current class, as meder said.
See the PHP Docs. It's explained under the first example.
You can use stri_detect_fixed function from stringi
package
stri_detect_fixed(c("REVERSE223","GENJJS"),"REVERSE")
[1] TRUE FALSE
First, keep in mind that, in its precise definition, a module is an object in the memory of a Python interpreter, often created by reading one or more files from disk. While we may informally call a disk file such as a/b/c.py
a "module," it doesn't actually become one until it's combined with information from several other sources (such as sys.path
) to create the module object.
(Note, for example, that two modules with different names can be loaded from the same file, depending on sys.path
and other settings. This is exactly what happens with python -m my.module
followed by an import my.module
in the interpreter; there will be two module objects, __main__
and my.module
, both created from the same file on disk, my/module.py
.)
A package is a module that may have submodules (including subpackages). Not all modules can do this. As an example, create a small module hierarchy:
$ mkdir -p a/b
$ touch a/b/c.py
Ensure that there are no other files under a
. Start a Python 3.4 or later interpreter (e.g., with python3 -i
) and examine the results of the following statements:
import a
a ? <module 'a' (namespace)>
a.b ? AttributeError: module 'a' has no attribute 'b'
import a.b.c
a.b ? <module 'a.b' (namespace)>
a.b.c ? <module 'a.b.c' from '/home/cjs/a/b/c.py'>
Modules a
and a.b
are packages (in fact, a certain kind of package called a "namespace package," though we wont' worry about that here). However, module a.b.c
is not a package. We can demonstrate this by adding another file, a/b.py
to the directory structure above and starting a fresh interpreter:
import a.b.c
? ImportError: No module named 'a.b.c'; 'a.b' is not a package
import a.b
a ? <module 'a' (namespace)>
a.__path__ ? _NamespacePath(['/.../a'])
a.b ? <module 'a.b' from '/home/cjs/tmp/a/b.py'>
a.b.__path__ ? AttributeError: 'module' object has no attribute '__path__'
Python ensures that all parent modules are loaded before a child module is loaded. Above it finds that a/
is a directory, and so creates a namespace package a
, and that a/b.py
is a Python source file which it loads and uses to create a (non-package) module a.b
. At this point you cannot have a module a.b.c
because a.b
is not a package, and thus cannot have submodules.
You can also see here that the package module a
has a __path__
attribute (packages must have this) but the non-package module a.b
does not.
The two queries express the same question. Apparently the query optimizer chooses two different execution plans. My guess would be that the distinct
approach is executed like:
business_key
values to a temporary tableThe group by
could be executed like:
business key
in a hashtableThe first method optimizes for memory usage: it would still perform reasonably well when part of the temporary table has to be swapped out. The second method optimizes for speed, but potentially requires a large amount of memory if there are a lot of different keys.
Since you either have enough memory or few different keys, the second method outperforms the first. It's not unusual to see performance differences of 10x or even 100x between two execution plans.
It's not so difficult.
You can inspect the available functions of the loaded object, and if you find the one you're looking for by name, then snoop its expected parms, if any. If it's the call you're trying to find, then call it using the MethodInfo object's Invoke method.
Another option is to simply build your external objects to an interface, and cast the loaded object to that interface. If successful, call the function natively.
This is pretty simple stuff.

I managed to connect to postgres with SQL Developer. I downloaded postgres jdbc driver and saved it in a folder. I run SQL Developer -> Tools -> Preferences -> Search -> JDBC I defined postgres jdbc driver for the Database and Data Modeler (optional).
This is the trick. When creating new connection define Hostname like localhost/crm? where crm is the database name. Test the connection, works fine.
Use ...from table(... :
create or replace type numbertype
as object
(nr number(20,10) )
/
create or replace type number_table
as table of numbertype
/
create or replace procedure tableselect
( p_numbers in number_table
, p_ref_result out sys_refcursor)
is
begin
open p_ref_result for
select *
from employees , (select /*+ cardinality(tab 10) */ tab.nr from table(p_numbers) tab) tbnrs
where id = tbnrs.nr;
end;
/
This is one of the rare cases where you need a hint, else Oracle will not use the index on column id. One of the advantages of this approach is that Oracle doesn't need to hard parse the query again and again. Using a temporary table is most of the times slower.
edit 1 simplified the procedure (thanks to jimmyorr) + example
create or replace procedure tableselect
( p_numbers in number_table
, p_ref_result out sys_refcursor)
is
begin
open p_ref_result for
select /*+ cardinality(tab 10) */ emp.*
from employees emp
, table(p_numbers) tab
where tab.nr = id;
end;
/
Example:
set serveroutput on
create table employees ( id number(10),name varchar2(100));
insert into employees values (3,'Raymond');
insert into employees values (4,'Hans');
commit;
declare
l_number number_table := number_table();
l_sys_refcursor sys_refcursor;
l_employee employees%rowtype;
begin
l_number.extend;
l_number(1) := numbertype(3);
l_number.extend;
l_number(2) := numbertype(4);
tableselect(l_number, l_sys_refcursor);
loop
fetch l_sys_refcursor into l_employee;
exit when l_sys_refcursor%notfound;
dbms_output.put_line(l_employee.name);
end loop;
close l_sys_refcursor;
end;
/
This will output:

Hans
format
supports a percentage floating point precision type:
>>> print "{0:.0%}".format(1./3)
33%
If you don't want integer division, you can import Python3's division from __future__
:
>>> from __future__ import division
>>> 1 / 3
0.3333333333333333
# The above 33% example would could now be written without the explicit
# float conversion:
>>> print "{0:.0f}%".format(1/3 * 100)
33%
# Or even shorter using the format mini language:
>>> print "{:.0%}".format(1/3)
33%
Borrowing, slightly enhancing and simplifying from this Blog post the following simple SQL statement seems to do the job quite well:
SELECT DISTINCT (:val) "Search Value", TABLE_NAME "Table", COLUMN_NAME "Column"
FROM cols,
TABLE (XMLSEQUENCE (DBMS_XMLGEN.GETXMLTYPE(
'SELECT "' || COLUMN_NAME || '" FROM "' || TABLE_NAME || '" WHERE UPPER("'
|| COLUMN_NAME || '") LIKE UPPER(''%' || :val || '%'')' ).EXTRACT ('ROWSET/ROW/*')))
ORDER BY "Table";
XAML :
<DataGrid x:Name="dgv_Students" AutoGenerateColumns="False" ItemsSource="{Binding People}" Margin="10,20,10,0" Style="{StaticResource AzureDataGrid}" FontFamily="B Yekan" Background="#FFB9D1BA" >
<DataGrid.Columns>
<DataGridTemplateColumn>
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<Button Click="Button_Click_dgvs">Text</Button>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
</DataGrid.Columns>
Code Behind :
private IEnumerable<DataGridRow> GetDataGridRowsForButtons(DataGrid grid)
{ //IQueryable
var itemsSource = grid.ItemsSource as IEnumerable;
if (null == itemsSource) yield return null;
foreach (var item in itemsSource)
{
var row = grid.ItemContainerGenerator.ContainerFromItem(item) as DataGridRow;
if (null != row & row.IsSelected) yield return row;
}
}
void Button_Click_dgvs(object sender, RoutedEventArgs e)
{
for (var vis = sender as Visual; vis != null; vis = VisualTreeHelper.GetParent(vis) as Visual)
if (vis is DataGridRow)
{
// var row = (DataGrid)vis;
var rows = GetDataGridRowsForButtons(dgv_Students);
string id;
foreach (DataGridRow dr in rows)
{
id = (dr.Item as tbl_student).Identification_code;
MessageBox.Show(id);
break;
}
break;
}
}
After clicking on the Button, the ID of that row is returned to you and you can use it for your Button name.

If a function does not return anything, e.g.:
def test():
pass
it has an implicit return value of None
.
Thus, as your pick*
methods do not return anything, e.g.:
def pickEasy():
word = random.choice(easyWords)
word = str(word)
for i in range(1, len(word) + 1):
wordCount.append("_")
the lines that call them, e.g.:
word = pickEasy()
set word
to None
, so wordInput
in getInput
is None
. This means that:
if guess in wordInput:
is the equivalent of:
if guess in None:
and None
is an instance of NoneType
which does not provide iterator/iteration functionality, so you get that type error.
The fix is to add the return type:
def pickEasy():
word = random.choice(easyWords)
word = str(word)
for i in range(1, len(word) + 1):
wordCount.append("_")
return word

Oracle optimizer chooses join order of tables for inner join. Optimizer chooses the join order of tables only in simple FROM clauses . U can check the oracle documentation in their website. And for the left, right outer join the most voted answer is right. The optimizer chooses the optimal join order as well as the optimal index for each table. The join order can affect which index is the best choice. The optimizer can choose an index as the access path for a table if it is the inner table, but not if it is the outer table (and there are no further qualifications).
The optimizer chooses the join order of tables only in simple FROM clauses. Most joins using the JOIN keyword are flattened into simple joins, so the optimizer chooses their join order.
The optimizer does not choose the join order for outer joins; it uses the order specified in the statement.
When selecting a join order, the optimizer takes into account: The size of each table The indexes available on each table Whether an index on a table is useful in a particular join order The number of rows and pages to be scanned for each table in each join order
Your update syntax is incorrect. Please check Update Syntax for the correct syntax.

Well, it's fairly simple to do.
On the window resize event handler, calculate how much the window has grown/shrunk, and use that fraction to adjust 1) Height, 2) Width, 3) Canvas.Top, 4) Canvas.Left properties of all the child controls inside the canvas.
Here's the code:
private void window1_SizeChanged(object sender, SizeChangedEventArgs e)
{
myCanvas.Width = e.NewSize.Width;
myCanvas.Height = e.NewSize.Height;
double xChange = 1, yChange = 1;
if (e.PreviousSize.Width != 0)
xChange = (e.NewSize.Width/e.PreviousSize.Width);
if (e.PreviousSize.Height != 0)
yChange = (e.NewSize.Height / e.PreviousSize.Height);
foreach (FrameworkElement fe in myCanvas.Children )
{
/*because I didn't want to resize the grid I'm having inside the canvas in this particular instance. (doing that from xaml) */
if (fe is Grid == false)
{
fe.Height = fe.ActualHeight * yChange;
fe.Width = fe.ActualWidth * xChange;
Canvas.SetTop(fe, Canvas.GetTop(fe) * yChange);
Canvas.SetLeft(fe, Canvas.GetLeft(fe) * xChange);
}
}
}

By your tags, I'm assuming your using Github. Why not create some branch protection rules for your master branch? That way even if you do try to push to master, it will reject it.
1) Go to the 'Settings' tab of your repo on Github.
2) Click on 'Branches' on the left side-menu.
3) Click 'Add rule'
4) Enter 'master' for a branch pattern.
5) Check off 'Require pull request reviews before merging'
I would also recommend doing the same for your dev branch.
GestureDetector.SimpleOnGestureListener has methods to help in these 3 cases;
GestureDetector gestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {

@Override
public boolean onSingleTapUp(MotionEvent motionEvent) {
return true;
}
//for detecting a press event. Code for drag can be added here.
@Override
public void onShowPress(MotionEvent e) {
View child = recyclerView.findChildViewUnder(e.getX(), e.getY());
ClipboardManager clipboardManager = (ClipboardManager) context.getSystemService(Context.CLIPBOARD_SERVICE);
ClipData clipData = ClipData.newPlainText("..", "...");
clipboardManager.setPrimaryClip(clipData);
ConceptDragShadowBuilder dragShadowBuilder = new CustomDragShadowBuilder(child);
// drag child view.
child.startDrag(clipData, dragShadowBuilder, child, 0);
}
//for detecting longpress event

public void onLongPress(MotionEvent e) {
super.onLongPress(e);
}
});
You can use bit.ly api to create facebook short urls find the documentation here http://api.bitly.com
If a collection is iterable, then it can be iterated using an iterator (and consequently can be used in a for each loop.) The iterator is the actual object that will iterate through the collection.
if (value == "") {
// it is empty
}
If you want to do this kind of testing, you’ll love the UI Automation support in iOS 4. You can write JavaScript to simulate button presses, etc. fairly easily, though the documentation (especially the getting-started part) is a bit sparse.

JavaScript now has equivalents for both the Elvis Operator and the Safe Navigation Operator.
Safe Property Access
The optional chaining operator (?.
) is currently a stage 4 ECMAScript proposal. You can use it today with Babel.
// `undefined` if either `a` or `b` are `null`/`undefined`. `a.b.c` otherwise.
const myVariable = a?.b?.c;
The logical AND operator (&&
) is the "old", more-verbose way to handle this scenario.
const myVariable = a && a.b && a.b.c;
Providing a Default
The nullish coalescing operator (??
) is currently a stage 4 ECMAScript proposal. You can use it today with Babel. It allows you to set a default value if the left-hand side of the operator is a nullary value (null
/undefined
).
const myVariable = a?.b?.c ?? 'Some other value';
// Evaluates to 'Some other value'
const myVariable2 = null ?? 'Some other value';
// Evaluates to ''
const myVariable3 = '' ?? 'Some other value';
The logical OR operator (||
) is an alternative solution with slightly different behavior. It allows you to set a default value if the left-hand side of the operator is falsy. Note that the result of myVariable3
below differs from myVariable3
above.
const myVariable = a?.b?.c || 'Some other value';
// Evaluates to 'Some other value'
const myVariable2 = null || 'Some other value';
// Evaluates to 'Some other value'
const myVariable3 = '' || 'Some other value';
It seems that the accepted answers are no longer the case when using React hooks. You can see in this code sandbox that the class component is rerendered when the state is set to the same value, while in the function component, setting the state to the same value doesn't cause a rerender.
We draw a solid line if and only if we have an ID-dependent relationship; otherwise it would be a dashed line.
Consider a weak but not ID-dependent relationship; We draw a dashed line because it is a weak relationship.
Your code should look like:
<?php
if ( that_happened ) {
header("HTTP/1.0 500 Internal Server Error");
die();
}
if ( something_else_happened ) {
header("HTTP/1.0 500 Internal Server Error");
die();
}
// Your function should return FALSE if something goes wrong
if ( !update_database() ) {
header("HTTP/1.0 500 Internal Server Error");
die();
}
// the script can also fail on the above line
// e.g. a mysql error occurred
header('HTTP/1.1 200 OK');
?>
I assume you stop execution if something goes wrong.
To fix your code you can simply change [Cov]
to Cov.values
, the first parameter of pd.DataFrame
will become a multi-dimensional numpy
array:
Cov = pd.read_csv("path/to/file.txt", sep='\t')
Frame=pd.DataFrame(Cov.values, columns = ["Sequence", "Start", "End", "Coverage"])
Frame.to_csv("path/to/file.txt", sep='\t')
But the smartest solution still is use pd.read_excel
with header=None
and names=columns_list
.
Just try /s
as listed below.
As the last line in the batch file type:

Permissions that Imply Feature Requirements
example, the android.hardware.bluetooth feature was added in Android 2.2 (API level 8), but the bluetooth API that it refers to was added in Android 2.0 (API level 5). Because of this, some apps were able to use the API before they had the ability to declare that they require the API via the system.
To prevent those apps from being made available unintentionally, Google Play assumes that certain hardware-related permissions indicate that the underlying hardware features are required by default. For instance, applications that use Bluetooth must request the BLUETOOTH permission in a element — for legacy apps, Google Play assumes that the permission declaration means that the underlying android.hardware.bluetooth feature is required by the application and sets up filtering based on that feature.
The table below lists permissions that imply feature requirements equivalent to those declared in elements. Note that declarations, including any declared android:required attribute, always take precedence over features implied by the permissions below.
For any of the permissions below, you can disable filtering based on the implied feature by explicitly declaring the implied feature explicitly, in a element, with an android:required="false" attribute. For example, to disable any filtering based on the CAMERA permission, you would add this declaration to the manifest file:
<uses-feature android:name="android.hardware.camera" android:required="false" />
<uses-feature android:name="android.hardware.bluetooth" android:required="false" />
<uses-feature android:name="android.hardware.location" android:required="false" />
<uses-feature android:name="android.hardware.location.gps" android:required="false" />
<uses-feature android:name="android.hardware.telephony" android:required="false" />
<uses-feature android:name="android.hardware.wifi" android:required="false" />
http://developer.android.com/guide/topics/manifest/uses-feature-element.html#permissions
You could use x ** (1. / 3)
to compute the (floating-point) cube root of x
.
The slight subtlety here is that this works differently for negative numbers in Python 2 and 3. The following code, however, handles that:
def is_perfect_cube(x):
x = abs(x)
return int(round(x ** (1. / 3))) ** 3 == x
print(is_perfect_cube(63))
print(is_perfect_cube(64))
print(is_perfect_cube(65))
print(is_perfect_cube(-63))
print(is_perfect_cube(-64))
print(is_perfect_cube(-65))
print(is_perfect_cube(2146689000)) # no other currently posted solution
# handles this correctly
This takes the cube root of x
, rounds it to the nearest integer, raises to the third power, and finally checks whether the result equals x
.
The reason to take the absolute value is to make the code work correctly for negative numbers across Python versions (Python 2 and 3 treat raising negative numbers to fractional powers differently).

I found the following approach to be the most effective for sampling a DataFrame:
print(df[A:B]) ## 'A' and 'B' are the first and last records in range
For example, print(df[10:15])
will print rows 10 through 15 - inclusive - from your data set.
#include <stdio.h>
#include <time.h>
int main ()
{
time_t rawtime;
struct tm * timeinfo;
time ( &rawtime );
timeinfo = localtime ( &rawtime );
printf ( "Current local time and date: %s", asctime (timeinfo) );
return 0;
}
forEach()
can be implemented to be faster than for-each loop, because the iterable knows the best way to iterate its elements, as opposed to the standard iterator way. So the difference is loop internally or loop externally.
For example ArrayList.forEach(action)
may be simply implemented as
for(int i=0; i<size; i++)
action.accept(elements[i])
as opposed to the for-each loop which requires a lot of scaffolding
Iterator iter = list.iterator();
while(iter.hasNext())
Object next = iter.next();
do something with `next`
However, we also need to account for two overhead costs by using forEach()
, one is making the lambda object, the other is invoking the lambda method. They are probably not significant.
see also http://journal.stuffwithstuff.com/2013/01/13/iteration-inside-and-out/ for comparing internal/external iterations for different use cases.

Need not calculate your div height,padding,margin and borders. It will take care.
In addition to CMS´ answer you may want to consider putting the style in an external stylesheet and assign the style to the id, like this:
#divCheckbox {
display: none;
}
If an Object variable is null, one cannot call an equals() method upon it, thus an object reference check of null is proper.

Fromthe Javadoc of Method.invoke():
If the underlying method is static, then the specified obj argument is ignored. It may be null.

p==5 ? true
p=="5" ? true
p==="5" ? false
=== means same type also same value == just same value
Yes, I can give you the outline but my Python is a bit rusty and I'm too busy to explain in detail.
Basically, you need to put a proxy in the method that will call the original, eg:
class fred(object):
def blog(self):
print "We Blog"
class methCallLogger(object):
def __init__(self, meth):
self.meth = meth
def __call__(self, code=None):
self.meth()
# would also log the fact that it invoked the method
#example
f = fred()
f.blog = methCallLogger(f.blog)
This StackOverflow answer about callable may help you understand the above.
In more detail:
Although the answer was accepted, due to the interesting discussion with Glenn and having a few minutes free, I wanted to enlarge on my answer:
# helper class defined elsewhere
class methCallLogger(object):
def __init__(self, meth):
self.meth = meth
self.was_called = False
def __call__(self, code=None):
self.meth()
self.was_called = True
#example
class fred(object):
def blog(self):
print "We Blog"
f = fred()
g = fred()
f.blog = methCallLogger(f.blog)
g.blog = methCallLogger(g.blog)
f.blog()
assert(f.blog.was_called)
assert(not g.blog.was_called)
In order to set the datepicker to a certain default time (the current date in my case) on loading, AND then have the option to choose another date the syntax is :
$(function() {
// initialize the datapicker
$("#date").datepicker();
// set the time
var currentDate = new Date();
$("#date").datepicker("setDate",currentDate);
// set the options for the button
$("#date").datepicker("option",{
dateFormat: 'dd/mm',
showOn: "button",
// whatever option Or event you want
});
});
I had the same issue but I found the solution to it. Basically "origin" is another name from where your project was cloned. Now the error
fatal: remote origin already exists.
LITERALLY means origin already exists. And hence to solve this issue, our goal should be to remove it. For this purpose:
git remote rm origin
Now add it again
git remote add origin https://github.com/__enter your username here__/__your repositoryname.git__
This did fix my issue.
TL;DR ...and late to the party, but that short explanation might help future googlers..
In general that error message means that the replacement doesn't fit into the corresponding column of the dataframe.
A minimal example:
df <- data.frame(a = 1:2); df$a <- 1:3
throws the error
Error in
$<-.data.frame
(*tmp*
, a, value = 1:3) : replacement has 3 rows, data has 2
which is clear, because the vector a
of df
has 2 entries (rows) whilst the vector we try to replace it has 3 entries (rows).
The problem with the two Powershell answers here is that the prefix can end up being duplicated since the script will potentially run over the file both before and after it has been renamed, depending on the directory being resorted as the renaming process runs. To get around this, simply use the -Exclude
option:
Get-ChildItem -Exclude "house chores-*" | rename-item -NewName { "house chores-" + $_.Name }
This will prevent the process from renaming any one file more than once.
I'm using CentOS 7 with virtualmin and three PHP versions. I also have REMI repo enabled. it worked for me:
Just append PHP major version number like this php{version number}-xml
. And run yum install
yum install php70-php-xml
yum install php71-php-xml
yum install php72-php-xml
Don't forget to restart Apache:
service httpd restart
You can simply use shape method
df[df['LastName'] == 'Smith'].shape
Output
(1,1)
Which indicates 1 row and 1 column. This way you can get the idea of whole datasets
Let me explain the above code
DataframeName[DataframeName['Column_name'] == 'Value to match in column']
What happens when you set all of the attributes in one attr()
command like so
$(this).attr({
id : this.id + '_' + new_id,
name: this.name + '_' + new_id,
value: 'test'
});
I am aware this question is a bit dated, but I would like to share the method I normally use to find .c and .h files:
tree -if | grep \\.[ch]\\b | xargs -n 1 grep -H "#include"
or if you need the line number as well:
tree -if | grep \\.[ch]\\b | xargs -n 1 grep -nH "#include"
Your css is fine, but I think it's not applying on divs. Just write simple class name and then try. You can check it at Jsfiddle.

You need to change your text to 'Plain text' before pasting into the HTML document. This looks like an error I've had before by pasting straight from MS word.
MS word and other rich text editors often place hidden or invalid chars into your code. Try using —
for your dashes, or ’
for apostrophes (etc), to eliminate the need for relying on your char encoding.
A very old (ca 1990) trick to get the total size of the environment variables:
set > test
dir test
del test
Greybox cannot handle forms inside it on its own. It requires a forms plugin. No iframes or external html files needed. Don't forget to download the greybox.css file too as the page misses that bit out.
Kiss Jquery UI goodbye and a lightbox hello. You can get it here.
You can use IIF for a similar result.
Note that you can nest the IIF statements to handle multiple cases. There is an example here: http://forums.devshed.com/database-management-46/query-ms-access-iif-statement-multiple-conditions-358130.html
SELECT IIf([Combinaison] = "Mike", 12, IIf([Combinaison] = "Steve", 13)) As Answer

I would do this:
data["list"].append({'b':'2'})
so simply you are adding an object to the list that is present in "data"
Well, you are using both frame.setSize()
and frame.pack()
.
You should use one of them at one time.
Using setSize()
you can give the size of frame you want but if you use pack()
, it will automatically change the size of the frames according to the size of components in it. It will not consider the size you have mentioned earlier.
Try removing frame.pack()
from your code or putting it before setting size and then run it.
sort --random-sort $FILE | head -n 1
(I like the shuf approach above even better though - I didn't even know that existed and I would have never found that tool on my own)

I agree with stephenbayer. But since it is a webservice, it is easier for end-user to use just one form of the webmethod, than using multiple versions of the same method. I think in this situation Nullable Types are perfect for optional parameters.
public void Foo(int a, int b, int? c)
{
if(c.HasValue)
{
// do something with a,b and c
}
else
{
// do something with a and b only
}
}
All standard implementations of java.util.List
already implement java.io.Serializable
.
So even though java.util.List
itself is not a subtype of java.io.Serializable
, it should be safe to cast the list to Serializable
, as long as you know it's one of the standard implementations like ArrayList
or LinkedList
.
If you're not sure, then copy the list first (using something like new ArrayList(myList)
), then you know it's serializable.
An equivalent statement would be
select * from [TableName] limit 5

If you only need it once, it's overkill to load a plugin.
For a date "dd/mm/yyyy", this works for me:
new Date(d.date.substring(6, 10),d.date.substring(3, 5)-1,d.date.substring(0, 2));
Just invert month and day for mm/dd/yyyy, the syntax is
new Date(y,m,d)
Why don't you use spring's TransactionTemplate
to programmatically control transactions? You could also restructure your code so that each "transaction block" has it's own @Transactional
method, but given that it's a test I would opt for programmatic control of your transactions.
Also note that the @Transactional
annotation on your runnable won't work (unless you are using aspectj) as the runnables aren't managed by spring!
@RunWith(SpringJUnit4ClassRunner.class)
//other spring-test annotations; as your database context is dirty due to the committed transaction you might want to consider using @DirtiesContext
public class TransactionTemplateTest {
@Autowired
PlatformTransactionManager platformTransactionManager;
TransactionTemplate transactionTemplate;
@Before
public void setUp() throws Exception {
transactionTemplate = new TransactionTemplate(platformTransactionManager);
}
@Test //note that there is no @Transactional configured for the method
public void test() throws InterruptedException {
final Contract c1 = transactionTemplate.execute(new TransactionCallback<Contract>() {
@Override
public Contract doInTransaction(TransactionStatus status) {
Contract c = contractDOD.getNewTransientContract(15);
contractRepository.save(c);
return c;
}
});
ExecutorService executorService = Executors.newFixedThreadPool(5);
for (int i = 0; i < 5; ++i) {
executorService.execute(new Runnable() {
@Override //note that there is no @Transactional configured for the method
public void run() {
transactionTemplate.execute(new TransactionCallback<Object>() {
@Override
public Object doInTransaction(TransactionStatus status) {
// do whatever you want to do with c1
return null;
}
});
}
});
}
executorService.shutdown();
executorService.awaitTermination(10, TimeUnit.SECONDS);
transactionTemplate.execute(new TransactionCallback<Object>() {
@Override
public Object doInTransaction(TransactionStatus status) {
// validate test results in transaction
return null;
}
});
}
}
The other way to make your submodule to check out the branch is to go the .gitmodules
file in the root folder and add the field branch
in the module configuration as following:
branch = <branch-name-you-want-module-to-checkout>
If the image is part of the layout it might be "View.VISIBLE" but that doesn't mean it's within the confines of the visible screen. If that's what you're after; this will work:
Rect scrollBounds = new Rect();
scrollView.getHitRect(scrollBounds);
if (imageView.getLocalVisibleRect(scrollBounds)) {
// imageView is within the visible window
} else {
// imageView is not within the visible window
}
Do you only want the pixels or the whole image (including headers) as an byte array?
For pixels: Use the CopyPixels
method on Bitmap. Something like:
var bitmap = new BitmapImage(uri);
//Pixel array
byte[] pixels = new byte[width * height * 4]; //account for stride if necessary and whether the image is 32 bit, 16 bit etc.
bitmap.CopyPixels(..size, pixels, fullStride, 0);
You can iterate over the row data
$('#button').click(function () {
var ids = $.map(table.rows('.selected').data(), function (item) {
return item[0]
});
console.log(ids)
alert(table.rows('.selected').data().length + ' row(s) selected');
});
Demo: Fiddle
A column with default value:
CREATE TABLE <TableName>(
...
<ColumnName> <Type> DEFAULT <DefaultValue>
...
)
<DefaultValue>
is a placeholder for a:
(
expression )
Examples:
Count INTEGER DEFAULT 0,
LastSeen TEXT DEFAULT (datetime('now'))
The following commands will return only Java ProcessIDs. These commands are very useful especially whenever you want to feed another process by these return values (java PIDs).
sudo netstat -nlpt | awk '/java/ {print $7}' | tr '/java' ' '
sudo netstat -nlpt | awk '/java/ {print $7}' | sed 's/\/java/ /g'
But if you remove the latest pipe, you will be noticed these are java process
sudo netstat -nlpt | awk '/java/ {print $7}'
sudo netstat -nlpt | awk '/java/ {print $7}'
You have to use parseInt() to convert
For eg.
var z = parseInt(x) + parseInt(y);
use parseFloat() if you want to handle float value.
Right-click on the module, select "Add framework support...", and check the "Maven" technology.
(This also creates a pom.xml
for you to modify.)
If you mean adding source repository elements, I think you need to do that manually–not sure.
Pre-IntelliJ 13 this won't convert the project to the Maven Standard Directory Layout, 13+ it will.

String strDate = "Current Time : " + mdformat.format(calendar.getTime());
Consistency is the key to any naming standard. As long as it's logical and consistent, you're 99% there.
The standard itself is very much personal preference - so if you like your standard, then run with it.
To answer your question outright - no, MySQL doesn't have a preferred naming convention/standard, so rolling your own is fine (and yours seems logical).
NuPKG files are just zip files, so anything that can process a zip file should be able to process a nupkg file, i.e, 7zip.
Use:
string json = "{\r\n \"LOINC_NUM\": \"10362-2\",\r\n}";
var result = JObject.Parse(json.Replace(System.Environment.NewLine, string.Empty));
decimal d = // your number..
decimal t = d - Math.Floor(d);
if(t >= 0.3d && t <= 0.7d)
{
return Math.Floor(d) + 0.5d;
}
else if(t>0.7d)
return Math.Ceil(d);
return Math.Floor(d);

Another option is to use DecimalFormat to format your numeric String. Here is one other way to do the job without having to use String.format if you are stuck in the pre 1.5 world:
static String intToString(int num, int digits) {
assert digits > 0 : "Invalid number of digits";
// create variable length array of zeros
char[] zeros = new char[digits];
Arrays.fill(zeros, '0');
// format number as String
DecimalFormat df = new DecimalFormat(String.valueOf(zeros));
return df.format(num);
}
Any number of files in a directory are a single package; symbols declared in one file are available to the others without any import
s or qualifiers. All of the files do need the same package foo
declaration at the top (or you'll get an error from go build
).
You do need GOPATH
set to the directory where your pkg
, src
, and bin
directories reside. This is just a matter of preference, but it's common to have a single workspace for all your apps (sometimes $HOME
), not one per app.
Normally a Github path would be github.com/username/reponame
(not just github.com/xxxx
). So if you want to have main
and another package, you may end up doing something under workspace/src
like
github.com/
username/
reponame/
main.go // package main, importing "github.com/username/reponame/b"
b/
b.go // package b
Note you always import with the full github.com/...
path: relative imports aren't allowed in a workspace. If you get tired of typing paths, use goimports
. If you were getting by with go run
, it's time to switch to go build
: run
deals poorly with multiple-file main
s and I didn't bother to test but heard (from Dave Cheney here) go run
doesn't rebuild dirty dependencies.
Sounds like you've at least tried to set GOPATH to the right thing, so if you're still stuck, maybe include exactly how you set the environment variable (the command, etc.) and what command you ran and what error happened. Here are instructions on how to set it (and make the setting persistent) under Linux/UNIX and here is the Go team's advice on workspace setup. Maybe neither helps, but take a look and at least point to which part confuses you if you're confused.
Just a different way of listing/reading files from a jar URL and it does it recursively for nested jars
https://gist.github.com/trung/2cd90faab7f75b3bcbaa
URL urlResource = Thead.currentThread().getContextClassLoader().getResource("foo");
JarReader.read(urlResource, new InputStreamCallback() {
@Override
public void onFile(String name, InputStream is) throws IOException {
// got file name and content stream
}
});
While using Google reCaptcha with reCaptcha DLL file, we can validate it in C# as follows :
RecaptchaControl1.Validate();
bool _Varify = RecaptchaControl1.IsValid;
if (_Varify)
{
// Pice of code after validation.
}
Its works for me.

[[1]]
[1] 4 24
attr(,"match.length")
[1] 1 1
attr(,"useBytes")
[1] TRUE
or perhaps str_locate_all
from package stringr
which is a wrapper for gregexpr
stringi::stri_locate_all
(as of stringr
version 1.0)
library(stringr)
str_locate_all(pattern ='2', "the2quickbrownfoxeswere2tired")
[[1]]
start end
[1,] 4 4
[2,] 24 24
note that you could simply use stringi
library(stringi)
stri_locate_all(pattern = '2', "the2quickbrownfoxeswere2tired", fixed = TRUE)
Another option in base R
would be something like
lapply(strsplit(x, ''), function(x) which(x == '2'))
should work (given a character vector x
)
I tried this code working for me,get image directly from url
private class DownloadImageTask extends AsyncTask<String, Void, Bitmap> {
ImageView bmImage;
public DownloadImageTask(ImageView bmImage) {
this.bmImage = bmImage;
}
protected Bitmap doInBackground(String... urls) {
String urldisplay = urls[0];
Bitmap mIcon11 = null;
try {
InputStream in = new java.net.URL(urldisplay).openStream();
mIcon11 = BitmapFactory.decodeStream(in);
} catch (Exception e) {
Log.e("Error", e.getMessage());
e.printStackTrace();
}
return mIcon11;
}
protected void onPostExecute(Bitmap result) {
bmImage.setImageBitmap(result);
}
}
use inside onCreate() method
new DownloadImageTask((ImageView) findViewById(R.id.image)) .execute("http://scoopak.com/wp-content/uploads/2013/06/free-hd-natural-wallpapers-download-for-pc.jpg");
This will help in adjusting the emulator according to the webpage:
WebView wb;
//CALL THIS METHOD
wb.setInitialScale(50);
You can set the intial scale in percentage as shown above.
VC Code Version: 1.22.2 Go to: Code -> Preferences -> Keyboard Shortcuts (cmd + K; cms + S); Change (edit): "Add Selection To Next Find Match": "cmd + what you want" // for me this is "cmd + D" and I pur cmd + F; Go to "Copy Line Down": "cmd + D" //edit this and set cmd + D for example And for me that's all - I use mac;
With ES6: This is now part of the language:
function myFunc(a, b = 0) {
// function body
}
Please keep in mind that ES6 checks the values against undefined
and not against truthy-ness (so only real undefined values get the default value - falsy values like null will not default).
With ES5:
function myFunc(a,b) {
b = b || 0;
// b will be set either to b or to 0.
}
This works as long as all values you explicitly pass in are truthy.
Values that are not truthy as per MiniGod's comment: null, undefined, 0, false, ''
It's pretty common to see JavaScript libraries to do a bunch of checks on optional inputs before the function actually starts.
Add bottom:100%
to your #menu:hover ul li:hover ul
rule
#menu:hover ul li:hover ul {
position: absolute;
margin-top: 1px;
font: 10px;
bottom: 100%; /* added this attribute */
}
Or better yet to prevent the submenus from having the same effect, just add this rule
#menu>ul>li:hover>ul {
bottom:100%;
}
source: http://jsfiddle.net/W5FWW/4/
And to get back the border you can add the following attribute
#menu>ul>li:hover>ul {
bottom:100%;
border-bottom: 1px solid transparent
}
SELECT YEAR(t.summaryDateTime) as yr, GROUP_CONCAT(MONTHNAME(t.summaryDateTime)) AS month
FROM trading_summary t GROUP BY yr
Still you would need to process it in external script to get exactly the structure you're looking for.
For example use PHP's explode to create an array from list of month names and then use json_encode()
