Here's a complete (yet simple) example of redirecting after X seconds, while updating a counter div:
<html>_x000D_
<body>_x000D_
<div id="counter">5</div>_x000D_
<script>_x000D_
setInterval(function() {_x000D_
var div = document.querySelector("#counter");_x000D_
var count = div.textContent * 1 - 1;_x000D_
div.textContent = count;_x000D_
if (count <= 0) {_x000D_
window.location.replace("https://example.com");_x000D_
}_x000D_
}, 1000);_x000D_
</script>_x000D_
</body>_x000D_
</html>
_x000D_
The initial content of the counter
div is the number of seconds to wait.
If your table has no Id such as integer auto-increment, and no timestamp, you can still get the last row of a table with the following query.
select * from <tablename> offset ((select count(*) from <tablename>)-1)
For example, that could allow you to search through an updated flat file, find/confirm where the previous version ended, and copy the remaining lines to your table.
Yes. In Ruby the not equal to operator is:

Either return;
from the method early, or throw
an exception.
There is no other way to prevent further code from being executed short of exiting the process completely.
Yes, it is possible.
try:
...
except FirstException:
handle_first_one()
except SecondException:
handle_second_one()
except (ThirdException, FourthException, FifthException) as e:
handle_either_of_3rd_4th_or_5th()
except Exception:
handle_all_other_exceptions()
See: http://docs.python.org/tutorial/errors.html
The "as" keyword is used to assign the error to a variable so that the error can be investigated more thoroughly later on in the code. Also note that the parentheses for the triple exception case are needed in python 3. This page has more info: Catch multiple exceptions in one line (except block)
It doesn't matter is your app Boot or just raw Spring. There is just enough to inject org.springframework.core.env.Environment
to your bean.

A Minor contribution.
As many of them explain about 'when to use' and 'use with foreach'. I thought of adding Another States Difference here as requested in question about the difference between both IEnumerable an IEnumerator.
I created the below code sample based on the below discussion threads.
IEnumerable , IEnumerator vs foreach, when to use what What is the difference between IEnumerator and IEnumerable?
Enumerator preserves the state (iteration position) between function calls while iterations the other hand Enumerable does not.
Here is the tested example with comments to understand.
Experts please add/correct me.
static void EnumerableVsEnumeratorStateTest()
{
IList<int> numList = new List<int>();
numList.Add(1);
numList.Add(2);
numList.Add(3);
numList.Add(4);
numList.Add(5);
numList.Add(6);
Console.WriteLine("Using Enumerator - Remembers the state");
IterateFrom1to3(numList.GetEnumerator());
Console.WriteLine("Using Enumerable - Does not Remembers the state");
IterateFrom1to3Eb(numList);
Console.WriteLine("Using Enumerable - 2nd functions start from the item 1 in the collection");
}
static void IterateFrom1to3(IEnumerator<int> numColl)
{
while (numColl.MoveNext())
{
Console.WriteLine(numColl.Current.ToString());
if (numColl.Current > 3)
{
// This method called 3 times for 3 items (4,5,6) in the collection.
// It remembers the state and displays the continued values.
IterateFrom3to6(numColl);
}
}
}
static void IterateFrom3to6(IEnumerator<int> numColl)
{
while (numColl.MoveNext())
{
Console.WriteLine(numColl.Current.ToString());
}
}
static void IterateFrom1to3Eb(IEnumerable<int> numColl)
{
foreach (int num in numColl)
{
Console.WriteLine(num.ToString());
if (num>= 5)
{
// The below method invokes for the last 2 items.
//Since it doesnot persists the state it will displays entire collection 2 times.
IterateFrom3to6Eb(numColl);
}
}
}
static void IterateFrom3to6Eb(IEnumerable<int> numColl)
{
Console.WriteLine();
foreach (int num in numColl)
{
Console.WriteLine(num.ToString());
}
}
I've seen this issue when PYTHONPATH
was set to include the built-in site-packages
directory. Since Python looks there automatically it is unnecessary and can be removed.
While looking at the same problem, I found an example
<style type="text/css">
#topright {
position: absolute;
right: 0;
top: 0;
display: block;
height: 125px;
width: 125px;
background: url(TRbanner.gif) no-repeat;
text-indent: -999em;
text-decoration: none;
}
</style>
<a id="topright" href="#" title="TopRight">Top Right Link Text</a>
The trick here is to create a small, (I used GIMP) a PNG (or GIF) that has a transparent background, (and then just delete the opposite bottom corner.)

This is very simple you need to keep different names of every radio input group.

In projects that use the Gradle build system, what you want to change is the applicationId
in the build.gradle file. The build system uses this value to override anything specified by hand in the manifest file when it does the manifest merge and build.
For example, your module's build.gradle file looks something like this:
apply plugin: 'com.android.application'
android {
compileSdkVersion 20
buildToolsVersion "20.0.0"
defaultConfig {
// CHANGE THE APPLICATION ID BELOW
applicationId "com.example.fred.myapplication"
minSdkVersion 10
targetSdkVersion 20
versionCode 1
versionName "1.0"
}
}
applicationId
is the name the build system uses for the property that eventually gets written to the package
attribute of the manifest
tag in the manifest file. It was renamed to prevent confusion with the Java package name (which you have also tried to modify), which has nothing to do with it.

I would say in some cases it's ok to do nothing. Probably not something you should be doing by default, but in case there should be no way for the interrupt to happen, I'm not sure what else to do (probably logging error, but that does not affect program flow).
One case would be in case you have a task (blocking) queue. In case you have a daemon Thread handling these tasks and you do not interrupt the Thread by yourself (to my knowledge the jvm does not interrupt daemon threads on jvm shutdown), I see no way for the interrupt to happen, and therefore it could be just ignored. (I do know that a daemon thread may be killed by the jvm at any time and therefore are unsuitable in some cases).
EDIT: Another case might be guarded blocks, at least based on Oracle's tutorial at: http://docs.oracle.com/javase/tutorial/essential/concurrency/guardmeth.html

I sincerely hope this will help future searchers when googling for this common question.
Wrapping a <a>
around won't work (unless you set the <div>
to display:inline-block;
or display:block;
to the <a>
) because the div is s a block-level element and the <a>
is not.
<a href="http://www.example.com" style="display:block;">
<div>
content
</div>
</a>
<a href="http://www.example.com">
<div style="display:inline-block;">
content
</div>
</a>
<a href="http://www.example.com">
<span>
content
</span >
</a>
<a href="http://www.example.com">
content
</a>
But maybe you should skip the <div>
and choose a <span>
instead, or just the plain <a>
. And if you really want to make the div clickable, you could attach a javascript redirect with a onclick handler, somethign like:
document.getElementById("myId").setAttribute('onclick', 'location.href = "url"');
but I would recommend against that.
Try the below code:
[Route("/test")]
[HttpPost]
public async Task Test()
{
using (var reader = new StreamReader(Request.Body, Encoding.UTF8))
{
var textFromBody = await reader.ReadToEndAsync();
}
}
You can use grep -P
(perl regex) supported negative lookbehind
:
grep -P '(?<!g)loom\b' ~/projects/**/trunk/src/**/*.@(h|cpp)
I added \b
for word boundaries.
You can use parentheses to override rules of precedence.
To make values empty you can do the following:
$("#element").val('');
To get the selected value you can do:
var value = $("#element").val();
Where #element
is the id of the element you wish to select.
This was my solution for evaluating file sizes without using VB/perl/etc. and sticking with native windows shell commands:
FOR /F "tokens=4 delims= " %%i in ('dir /-C %temp% ^| find /i "filename.txt"') do (
IF %%i GTR 1000000 (
echo filename.txt filesize is greater than 1000000
) ELSE (
echo filename.txt filesize is less than 1000000
)
)
Not the cleanest solution, but it gets the job done.
If you want cmd.exe to not close, and able to continue to type, use
cmd /k
Just felt the need to clarify what /k
does (from windows website):
/k
: Carries out the command specified by string and continues.
So cmd /k
without follow up command at the end of bat file will just keep cmd.exe
window open for further use.
On the other hand pause
at the end of a batch file will simply pause the process and terminate cmd.exe
on first button press
Me, I'd do it something like this:
HTML:
onclick="myfunction({path:'/myController/myAction', ok:myfunctionOnOk, okArgs:['/myController2/myAction2','myParameter2'], cancel:myfunctionOnCancel, cancelArgs:['/myController3/myAction3','myParameter3']);"
JS:
function myfunction(params)
{
var path = params.path;
/* do stuff */
// on ok condition
params.ok(params.okArgs);
// on cancel condition
params.cancel(params.cancelArgs);
}
But then I'd also probable be binding a closure to a custom subscribed event. You need to add some detail to the question really, but being first-class functions are easily passable and getting params to them can be done any number of ways. I would avoid passing them as string labels though, the indirection is error prone.

I am late the party, but I wanted to point out one benefit that I found to using a magic square, namely that it can be used to get a reference to the square that would cause the win or loss on the next turn, rather than just being used to calculate when a game is over.
Take this magic square:
4 9 2
3 5 7
8 1 6
First, set up an scores
array that is incremented every time a move is made. See this answer for details. Now if we illegally play X twice in a row at [0,0] and [0,1], then the scores
array looks like this:
[7, 0, 0, 4, 3, 0, 4, 0];
And the board looks like this:
X . .
X . .
. . .
Then, all we have to do in order to get a reference to which square to win/block on is:
get_winning_move = function() {
for (var i = 0, i < scores.length; i++) {
// keep track of the number of times pieces were added to the row
// subtract when the opposite team adds a piece
if (scores[i].inc === 2) {
return 15 - state[i].val; // 8
}
}
}
In reality, the implementation requires a few additional tricks, like handling numbered keys (in JavaScript), but I found it pretty straightforward and enjoyed the recreational math.
You have a couple of things fighting in your strings.
mysql_real_escape_string()
)It's also possible that the single-quoted value is not present in the parameters to the first query. Your example is a proper name, after all, and only the second query seems to be dealing with names.
You'd be surprised to find out that 80/20 is quite a commonly occurring ratio, often referred to as the Pareto principle. It's usually a safe bet if you use that ratio.
However, depending on the training/validation methodology you employ, the ratio may change. For example: if you use 10-fold cross validation, then you would end up with a validation set of 10% at each fold.
There has been some research into what is the proper ratio between the training set and the validation set:
The fraction of patterns reserved for the validation set should be inversely proportional to the square root of the number of free adjustable parameters.
In their conclusion they specify a formula:
Validation set (v) to training set (t) size ratio, v/t, scales like ln(N/h-max), where N is the number of families of recognizers and h-max is the largest complexity of those families.
What they mean by complexity is:
Each family of recognizer is characterized by its complexity, which may or may not be related to the VC-dimension, the description length, the number of adjustable parameters, or other measures of complexity.
Taking the first rule of thumb (i.e.validation set should be inversely proportional to the square root of the number of free adjustable parameters), you can conclude that if you have 32 adjustable parameters, the square root of 32 is ~5.65, the fraction should be 1/5.65 or 0.177 (v/t). Roughly 17.7% should be reserved for validation and 82.3% for training.
I quite like the way the WordPress works with its enqueue and localize functions, so following that model, I wrote a simple class for putting a scripts into page according to the script dependencies, and for making additional data available for the script.
class mHeader {
private $scripts = array();
/**
* @param string $id Unique script identifier
* @param string $src Script src attribute
* @param array $deps An array of dependencies ( script identifiers ).
* @param array $data An array, data that will be json_encoded and available to the script.
*/
function enqueue_script($id, $src, $deps = array(), $data = array()) {
$this->scripts[$id] = array('src' => $src, 'deps' => $deps, 'data' => $data);
}
private function dependencies($script) {
if ($script['deps']) {
return array_map(array($this, 'dependencies'), array_intersect_key($this->scripts, array_flip($script['deps'])));
}
}
private function _unset($key, &$deps, &$out) {
$out[$key] = $this->scripts[$key];
unset($deps[$key]);
}
private function flattern(&$deps, &$out = array()) {
foreach($deps as $key => $value) {
empty($value) ? $this->_unset($key, $deps, $out) : $this->flattern( $deps[$key], $out);
}
}
function print_scripts() {
if (!$this->scripts)
return;
$deps = array_map(array($this, 'dependencies'), $this->scripts);
while ($deps)
$this->flattern($deps, $js);
foreach($js as $key => $script) {
$script['data'] && printf("<script> var %s = %s; </script>" . PHP_EOL, key($script['data']), json_encode(current( $script['data'])));
echo "<script id=\"$key-js\" src=\"$script[src]\" type=\"text/javascript\"></script>" . PHP_EOL;
}
}
}
The call to the enqueue_script()
function is for adding script, setting the source and dependencies on other scripts, and additional data needed for the script.
$header = new mHeader();
$header->enqueue_script('jquery-ui', '//ajax.googleapis.com/ajax/libs/jqueryui/1.10.4/jquery-ui.min.js', array('jquery'));
$header->enqueue_script('jquery', '//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js');
$header->enqueue_script('custom-script', '//custom-script.min.js', array('jquery-ui'), array('mydata' => array('value' => 20)));
$header->print_scripts();
And, print_scripts()
method of the above example will send this output:
<script id="jquery-js" src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js" type="text/javascript"></script>
<script id="jquery-ui-js" src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.4/jquery-ui.min.js" type="text/javascript"></script>
<script> var mydata = {"value":20}; </script>
<script id="custom-script-js" src="//custom-script.min.js" type="text/javascript"></script>
Regardless the fact that the script 'jquery' is enqueued after the 'jquery-ui', it is printed before because it is defined in 'jquery-ui' that it depends on 'jquery'.
Additional data for the 'custom-script' are inside a new script block and are placed in front of it, it contains mydata
object that holds additional data, now available to 'custom-script'.
You can use the mciSendString
API to play an MP3 or a WAV file:

IntPtr hWndCallback
);
mciSendString(@"close temp_alias", null, 0, IntPtr.Zero);
mciSendString(@"open ""music.mp3"" alias temp_alias", null, 0, IntPtr.Zero);
mciSendString("play temp_alias repeat", null, 0, IntPtr.Zero);
var myInt = int.parse('12345');
assert(myInt is int);
print(myInt); // 12345
print(myInt.runtimeType);
var myDouble = double.parse('123.45');
assert(myInt is double);
print(myDouble); // 123.45
print(myDouble.runtimeType);
A simple solution for me was to go to Properties -> Java Build Path -> Order and Export, then check the Apache Tomcat library. This is assumes you've already set Tomcat as your deployment target and are still getting the error.
Use the grepl

Sharing a few functions which I created for dates:
Please note that I wanted to get time for a particular location (not just UTC time). If you want UTC time, just remove loc variable and .In(loc) function call.
func GetTimeStamp() string {
loc, _ := time.LoadLocation("America/Los_Angeles")
t := time.Now().In(loc)
return t.Format("20060102150405")
}
func GetTodaysDate() string {
loc, _ := time.LoadLocation("America/Los_Angeles")
current_time := time.Now().In(loc)
return current_time.Format("2006-01-02")
}
func GetTodaysDateTime() string {
loc, _ := time.LoadLocation("America/Los_Angeles")
current_time := time.Now().In(loc)
return current_time.Format("2006-01-02 15:04:05")
}
func GetTodaysDateTimeFormatted() string {
loc, _ := time.LoadLocation("America/Los_Angeles")
current_time := time.Now().In(loc)
return current_time.Format("Jan 2, 2006 at 3:04 PM")
}
func GetTimeStampFromDate(dtformat string) string {
form := "Jan 2, 2006 at 3:04 PM"
t2, _ := time.Parse(form, dtformat)
return t2.Format("20060102150405")
}
I would suggest using
v = np.diff(t)
this is simple and easy to read.
But if you want v
to have the same length as t
then
v = np.diff([t[0]] + t) # for python 3.x
or
v = np.diff(t + [t[-1]])
FYI: this will only work for lists.
for numpy arrays
v = np.diff(np.append(t[0], t))
This can occur because of you are trying to checking out the repository by accessing it via a proxy server without enabling the proxy server in the place you need to change the settings in TortoiseSvn. So if you are using a proxy server make sure that you put a tick in "Enable Proxy Server" in Settings->Network and give your Server address and Port number in the relevant places. Now try to check out again.
Add the below declarations to your class:
public const SslProtocols _Tls12 = (SslProtocols)0x00000C00;
public const SecurityProtocolType Tls12 = (SecurityProtocolType)_Tls12;
After:
var client = new HttpClient();
And:
ServicePointManager.SecurityProtocol = Tls12;
System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 /*| SecurityProtocolType.Tls */| Tls12;
Happy? :)
You can insert into a varbinary(max) field using T-SQL within SQL Server Management Studio and in particular using the OPENROWSET commmand.
For example:
INSERT Production.ProductPhoto
(
ThumbnailPhoto,
ThumbnailPhotoFilePath,
LargePhoto,
LargePhotoFilePath
)
SELECT ThumbnailPhoto.*, null, null, N'tricycle_pink.gif'
FROM OPENROWSET
(BULK 'c:\images\tricycle.jpg', SINGLE_BLOB) ThumbnailPhoto
Take a look at the following documentation for a good example/walkthrough
Working With Large Value Types
Note that the file path in this case is relative to the targeted SQL server and not your client running this command.
This error may happen when mapping variables you defined in REST definition do not match with @PathVariable names.
Example: Suppose you defined in the REST definition
@GetMapping(value = "/{appId}", produces = "application/json", consumes = "application/json")
Then during the definition of the function, it should be
public ResponseEntity<List> getData(@PathVariable String appId)
This error may occur when you use any other variable other than defined in the REST controller definition with @PathVariable. Like, the below code will raise the error as ID is different than appId variable name:
public ResponseEntity<List> getData(@PathVariable String ID)
If you are looking for a direct approach and using a local
File in that case.
Try
<div
style={{ background-image: 'url(' + Image + ')', background-size: 'auto' }}
/>
This is the case of JS
with inline styling where Image
is a local file that you must have imported with a path.
You don't. The server you are making the request to has to implement CORS to grant JavaScript from your website access. Your JavaScript can't grant itself permission to access another website.
You can create several divs and do that:
<div style="width:100px; height:100px;">
<div style="position:relative; top:0px; left:0px; width:100px; height:100px; opacity:0.3;"><img src="urltoimage" alt=" " /></div>
<div style="position:relative; top:0px; left:0px; width:100px; height:100px;"> DIV with no opacity </div>
</div>
I did that couple times... Simple, yet effective...
It works like this:
<ScrollViewer VerticalScrollBarVisibility="Visible" HorizontalScrollBarVisibility="Disabled" Width="340" HorizontalAlignment="Left" Margin="12,0,0,0">
<StackPanel Name="stackPanel1" Width="311">
</StackPanel>
</ScrollViewer>
TextBox tb = new TextBox();
tb.TextChanged += new TextChangedEventHandler(TextBox_TextChanged);
stackPanel1.Children.Add(tb);
Every InvoiceItem
must have an Invoice
attached to it because of the not-null="true"
in the many-to-one mapping.
So the basic idea is you need to set up that explicit relationship in code. There are many ways to do that. On your class I see a setItems
method. I do NOT see an addInvoiceItem
method. When you set items, you need to loop through the set and call item.setInvoice(this)
on all of the items. If you implement an addItem
method, you need to do the same thing. Or you need to otherwise set the Invoice of every InvoiceItem
in the collection.
From my recent experience, JsonReader#setLenient
basically makes the parser very tolerant, even to allow malformed JSON data.
But for certain data retrieved from your trusted RESTful API(s), this error might be caused by trailing white spaces. In such cases, simply trim
the data would avoid the error:
String trimmed = result1.trim();
Then gson.fromJson(trimmed, T)
might work. Surely this only covers a special case, so YMMV.
The simplest way is this:
$my_array = array(
0 => array(
"name" => "john",
"id" => 4
),
1 => array(
"name" => "mark",
"id" => 152
),
2 => array(
"name" => "Eduard",
"id" => 152
)
);
if (array_search(152, array_column($my_array, 'id')) !== FALSE)
echo 'FOUND!';
else
echo 'NOT FOUND!';
You can define the variable in General Declarations and then initialise it in the first event that fires in your environment.
Alternatively, you could create yourself a class with the relevant properties and initialise them in the Initialise method
Assuming you have GNU find:
find . -size +10000k -printf '%s %f\n'
If you want a constant width for the size field, you can do something like:
find . -size +10000k -printf '%10s %f\n'
Note that -size +1000k
selects files of at least 10,240,000 bytes (k
is 1024, not 1000). You said in a comment that you want files bigger than 1M; if that's 1024*1024 bytes, then this:
find . -size +1M ...
will do the trick -- except that it will also print the size and name of files that are exactly 1024*1024 bytes. If that matters, you could use:
find . -size +1048575c ...
You need to decide just what criterion you want.
First you should ask yourself the following question: Do you really need an int?
The purpose of enums is to have a collection of items (constants), that have a meaning in the code without relying on an external value (like an int). Enums in Java can be used as an argument on switch statments and they can safely be compared using "==" equality operator (among others).
Proposal 1 (no int needed) :
Often there is no need for an integer behind it, then simply use this:
private enum DownloadType{
AUDIO, VIDEO, AUDIO_AND_VIDEO
}
Usage:
DownloadType downloadType = MyObj.getDownloadType();
if (downloadType == DownloadType.AUDIO) {
//...
}
//or
switch (downloadType) {
case AUDIO: //...
break;
case VIDEO: //...
break;
case AUDIO_AND_VIDEO: //...
break;
}
Proposal 2 (int needed) :
Nevertheless, sometimes it may be useful to convert an enum to an int (for instance if an external API expects int values). In this case I would advise to mark the methods as conversion methods using the toXxx()
-Style. For printing override toString()
.

Summary
ordinal()
for getting an integer of an enum, because this value may change, if you change the order (for example by inserting a value). If you are considering to use ordinal()
it might be better to use proposal 1.Something like this should do the trick (However, read after the snippet for more info)
CREATE PROCEDURE GetFilteredData()
BEGIN
DECLARE bDone INT;
DECLARE var1 CHAR(16); -- or approriate type
DECLARE Var2 INT;
DECLARE Var3 VARCHAR(50);
DECLARE curs CURSOR FOR SELECT something FROM somewhere WHERE some stuff;
DECLARE CONTINUE HANDLER FOR NOT FOUND SET bDone = 1;
DROP TEMPORARY TABLE IF EXISTS tblResults;
CREATE TEMPORARY TABLE IF NOT EXISTS tblResults (
--Fld1 type,
--Fld2 type,
--...
);
OPEN curs;
SET bDone = 0;
REPEAT
FETCH curs INTO var1,, b;

-- here for whatever_transformation_may_be_desired
INSERT INTO tblResults VALUES (var1, var2, var3 ...);
END IF;
UNTIL bDone END REPEAT;
CLOSE curs;
SELECT * FROM tblResults;
END
A few things to consider...
Concerning the snippet above:
More generally: trying to avoid needing a cursor.
I purposely named the cursor variable curs[e], because cursors are a mixed blessing. They can help us implement complicated business rules that may be difficult to express in the declarative form of SQL, but it then brings us to use the procedural (imperative) form of SQL, which is a general feature of SQL which is neither very friendly/expressive, programming-wise, and often less efficient performance-wise.
Maybe you can look into expressing the transformation and filtering desired in the context of a "plain" (declarative) SQL query.
If you want to take advantage of recent Python versions' async features, you can use aioftp (from the same family of libraries and developers as the more popular aiohttp library). Here is a code example taken from their client tutorial:
client = aioftp.Client()
await client.connect("ftp.server.com")
await client.login("user", "pass")
await client.download("tmp/test.py", "foo.py", write_into=True)
If you don't have to worry about any other changes you made and you just want to go back to the last commit, then you can do:
git reset .
git checkout .
git clean -f

A simple utility function I wrote that makes use of os.scandir()
instead of os.listdir()
.
import os
def count_files_in_dir(path: str) -> int:
file_entries = [entry for entry in os.scandir(path) if entry.is_file()]
return len(file_entries)
The main benefit is that, the need for os.path.is_file()
is eliminated and replaced with os.DirEntry
instance's is_file()
which also removes the need for os.path.join(DIR, file_name)
as shown in other answers.

I recommend the answer posted by Martin.
But you seem to be concerned about your queries getting too complex:
To create localized table for every table is making design and querying complex...
So you might be thinking, that instead of writing simple queries like this:
SELECT price, name, description FROM Products WHERE price < 100
...you would need to start writing queries like that:
SELECT
p.price, pt.name, pt.description
FROM
Products p JOIN ProductTranslations pt
ON (p.id = pt.id AND pt.lang = "en")
WHERE
price < 100
Not a very pretty perspective.
But instead of doing it manually you should develop your own database access class, that pre-parses the SQL that contains your special localization markup and converts it to the actual SQL you will need to send to the database.
Using that system might look something like this:
db.setLocale("en");
db.query("SELECT p.price, _(p.name), _(p.description)
FROM _(Products p) WHERE price < 100");
And I'm sure you can do even better that that.
The key is to have your tables and fields named in uniform way.
My setup was a little different using XAMPP. in httpd-xampp.conf I had to make the following change.
Alias /phpmyadmin "C:/xampp/phpMyAdmin/"
<Directory "C:/xampp/phpMyAdmin">
AllowOverride AuthConfig
Require local
ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
</Directory>
change to
Alias /phpmyadmin "C:/xampp/phpMyAdmin/"
<Directory "C:/xampp/phpMyAdmin">
AllowOverride AuthConfig
#makes it so I can config the database from anywhere
#change the line below
Require all granted
ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
</Directory>
I need to state that I'm brand new at this so I'm just hacking around but this is how I got it working.
If you've set the correct code signing certificate under Build Settings->Code Signing, then make sure you are also using the correct provisioning profile for Debug/Release mode as well.
I was having this issue because I was using an Ad-Hoc provisioning profile for both Debug/Release modes, which doesn't allow for a development profile to be used when doing a debug build.
If using Vagrant try reloading your box. This solved my issue.

There is nothing particularly tricky about the example you posted.
In a ternary operator, the first argument (the conditional) is evaluated and if the result is true
, the second argument is evaluated and returned, otherwise, the third is evaluated and returned. Each of those arguments can be any valid code block, including function calls.
Think of it this way:
var x = (1 < 2) ? true : false;
Could also be written as:
var x = (1 < 2) ? getTrueValue() : getFalseValue();
This is perfectly valid, and those functions can contain any arbitrary code, whether it is related to returning a value or not. Additionally, the results of the ternary operation don't have to be assigned to anything, just as function results do not have to be assigned to anything:
(1 < 2) ? getTrueValue() : getFalseValue();
Now simply replace those with any arbitrary functions, and you are left with something like your example:
(1 < 2) ? removeItem($this) : addItem($this);
Now your last example really doesn't need a ternary at all, as it can be written like this:
x = (1 < 2); // x will be set to "true"

This is a very old thread, but I am missing another in my opinion convenient solution:
I never revert a merge. I just create another branch from the revision where everything was ok and then cherry pick everything that needs to picked from the old branch which was added in between.
So, if the GIT history is like this:
I create a new branch from a, cherry pick c and d and then the new branch is clear from b. I can ever decide to do the merge of "b" in my new branch again. The old branch becomes deprecated and will be deleted if "b" is not necessary anymore or still in another (feature/hotfix) branch.
The only problem is now one of the very hardest things in computer science: How do you name the new branch? ;)
Ok, if you failed esp. in devel, you create newdevel as mentioned above, delete old devel and rename newdevel to devel. Mission accomplished. You can now merge the changes again when you want. It is like never merged before....

You can achieve the opening/closing of a tab by the combination of keys COMMAND + T or COMMAND + W (OSX). On other OSs you can use CONTROL + T / CONTROL + W.
In selenium you can emulate such behavior. You will need to create one webdriver and as many tabs as the tests you need.
Here it is the code.
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
driver = webdriver.Firefox()
driver.get("http://www.google.com/")
#open tab
driver.find_element_by_tag_name('body').send_keys(Keys.COMMAND + 't')
# You can use (Keys.CONTROL + 't') on other OSs
# Load a page
driver.get('http://stackoverflow.com/')
# Make the tests...
# close the tab
# (Keys.CONTROL + 'w') on other OSs.
driver.find_element_by_tag_name('body').send_keys(Keys.COMMAND + 'w')
driver.close()

First, we have to fetch all of the remote branches and tags from the existing repository to our local index:
git fetch origin
We can check for any missing branches that we need to create a local copy of:
git branch -a
Let’s use the SSH-cloned URL of our new repository to create a new remote in our existing local repository:
git remote add new-origin [email protected]:manakor/manascope.git
Now we are ready to push all local branches and tags to the new remote named new-origin:
git push --all new-origin
git push --tags new-origin
Let’s make new-origin the default remote:
git remote rm origin
Rename new-origin to just origin, so that it becomes the default remote:
git remote rename new-origin origin

As i've mentioned in other, similar questions, you may want to consider compressing the data as the default java serialization is a bit verbose. you do this by putting a GZIPInput/OutputStream between the Object streams and the Byte streams.
Good question. :) I don't have a complete answer...
That said, you can get a list of remote tags via git ls-remote
. To list the tags in the repository referenced by origin
, you'd run:
git ls-remote --tags origin
That returns a list of hashes and friendly tag names, like:
94bf6de8315d9a7b22385e86e1f5add9183bcb3c refs/tags/v0.1.3
cc047da6604bdd9a0e5ecbba3375ba6f09eed09d refs/tags/v0.1.4
...
2f2e45bedf67dedb8d1dc0d02612345ee5c893f2 refs/tags/v0.5.4
You could certainly put together a bash script to compare the tags generated by this list with the tags you have locally. Take a look at git show-ref --tags
, which generates the tag names in the same form as git ls-remote
).
As an aside, git show-ref
has an option that does the opposite of what you'd like. The following command would list all the tags on the remote branch that you don't have locally:
git ls-remote --tags origin | git show-ref --tags --exclude-existing
Was updating an old website using nuget (including .Net update and MVC update).
I deleted the System.Net.HTTP reference in VS2017 (it was to version 2.0.0.0) and re-added the reference, which then showed 4.2.0.0.
I then updated a ton of 'packages' using nuget and got the error message, then noticed something had reset the reference to 2.0.0.0, so I removed and re-added again and it works fine... bizarre.
I believe if you have 2 arrays of the same type that you want to combine into a third array, there's a very simple way to do that.
here's the code:
String[] theHTMLFiles = Directory.GetFiles(basePath, "*.html");
String[] thexmlFiles = Directory.GetFiles(basePath, "*.xml");
List<String> finalList = new List<String>(theHTMLFiles.Concat<string>(thexmlFiles));
String[] finalArray = finalList.ToArray();
#here is my answer using two function one for merge and another for divide and

print('list before sorting is',c)
def mergesort1(c,l,r):
i,j,k=0,0,0
while (i<len(l))&(j<len(r)):
if l[i]<r[j]:
c[k]=l[i]
i +=1
else:
c[k]=r[j]
j +=1
k +=1
while i<len(l):
c[k]=l[i]
i+=1
k+=1
while j<len(r):
c[k]=r[j]
j+=1
k+=1
return c
def mergesort(c):
if len(c)<2:
return c
else:
l=c[0:(len(c)//2)]
r=c[len(c)//2:len(c)]
mergesort(l)
mergesort(r)
return mergesort1(c,l,r)
An alternative way to go around the problem, is to make the name of the session cookie be port related. For example:
Your code could access the webserver configuration to find out which port your server uses, and name the cookie accordingly.
Keep in mind that your application will receive both cookies, and you need to request the one that corresponds to your port.
There is no need to have the exact port number in the cookie name, but this is more convenient.
In general, the cookie name could encode any other parameter specific to the server instance you use, so it can be decoded by the right context.
git remote manpage is pretty straightforward:
Use
Older (backwards-compatible) syntax:
$ git remote rm upstream
Newer syntax for newer git versions: (* see below)
$ git remote remove upstream
Then do:
$ git remote add upstream https://github.com/Foo/repos.git
or just update the URL directly:
$ git remote set-url upstream https://github.com/Foo/repos.git
or if you are comfortable with it, just update the .git/config directly - you can probably figure out what you need to change (left as exercise for the reader).
...
[remote "upstream"]
fetch = +refs/heads/*:refs/remotes/upstream/*
url = https://github.com/foo/repos.git
...

* Regarding 'git remote rm' vs 'git remote remove' - this changed around git 1.7.10.3 / 1.7.12 2 - see
Log message
remote: prefer subcommand name 'remove' to 'rm'
All remote subcommands are spelled out words except 'rm'. 'rm', being a
popular UNIX command name, may mislead users that there are also 'ls' or
'mv'. Use 'remove' to fit with the rest of subcommands.
'rm' is still supported and used in the test suite. It's just not
widely advertised.
Try:
mmatrix = np.zeros((nrows, ncols))
Since the shape parameter has to be an int or sequence of ints
http://docs.scipy.org/doc/numpy/reference/generated/numpy.zeros.html
Otherwise you are passing ncols
to np.zeros
as the dtype.
Simply copy this code and hope this works fine for you.

While you can't define a constructor signature in an interface, I feel it's worth mentioning that this may be a spot to consider an abstract class. Abstract classes can define unimplemented (abstract) method signatures in the same way as an interface, but can also have implemented (concrete) methods and constructors.
The downside is that, because it is a type of class, it cannot be used for any of the multiple inheritance type scenarios that an interface can.
I don't know an easy method to convert a date object to any time zone, but if you want to convert it to the local time zone, you can just convert it with Date.prototype.getTime()
to the corresponding number of milliseconds, and back again.
date = new Date('2016-05-24T13:07:20');
date = new Date(date.getTime());
For example, date.getHours()
will now return 15
instead of 13
if you are, like me, in Austria (and it's summer).
I've read that the various datetime functions may exhibit non-standard behaviour in some browsers, so test this first. I can confirm that it works in Chrome.
folks, I got this Bootstrap dropdown working. I modified the click event slightly in order to keep the currently-selected image. And as you see, the USD currency is the default selected :

<a class="btn btn-primary dropdown-toggle" data-toggle="dropdown" href="#"><img src="../../Images/flag-usd-small.png"> USD <span class="caret"></span></a>
<ul class="dropdown-menu">

Let me present to you a glorious but terrifying hack:
import types
def _obj():
return lambda: None
def LET(bindings, body, env=None):
'''Introduce local bindings.
ex: LET(('a', 1,
'b', 2),
lambda o: [o.a, o.b])
gives: [1, 2]
Bindings down the chain can depend on
the ones above them through a lambda.
ex: LET(('a', 1,
'b', lambda o: o.a + 1),
lambda o: o.b)
gives: 2
'''
if len(bindings) == 0:
return body(env)
env = env or _obj()
k, v = bindings[:2]
if isinstance(v, types.FunctionType):
v = v(env)
setattr(env, k, v)
return LET(bindings[2:], body, env)
You can now use this LET
form as such:
map(lambda x: LET(('y', x + 1,
'z', x - 1),
lambda o: o.y * o.z),
[1, 2, 3])
which gives: [0, 3, 8]
An instance method applies to an instance of the class (i.e. an object) whereas a class method applies to the class itself.
In C# a class method is marked static. Methods and properties not marked static are instance methods.
class Foo {
public static void ClassMethod() { ... }
public void InstanceMethod() { ... }
}
The string
class has a constructor that takes a NULL-terminated C-string:
char arr[ ] = "This is a test";
string str(arr);
// You can also assign directly to a string.
str = "This is another string";
// or
str = arr;
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.
mkdirs()
also creates parent directories in the path this File
represents.
javadocs for mkdirs()
:
Creates the directory named by this abstract pathname, including any necessary but nonexistent parent directories. Note that if this operation fails it may have succeeded in creating some of the necessary parent directories.
javadocs for mkdir()
:
Creates the directory named by this abstract pathname.
Example:
File f = new File("non_existing_dir/someDir");
System.out.println(f.mkdir());
System.out.println(f.mkdirs());
will yield false
for the first [and no dir will be created], and true
for the second, and you will have created non_existing_dir/someDir

Important: If you use the button element in an HTML form, different browsers will submit different values. Internet Explorer will submit the text between the
<button>
and</button>
tags, while other browsers will submit the content of the value attribute. Use the input element to create buttons in an HTML form.
From : http://www.w3schools.com/tags/tag_button.asp
If I understand correctly, the answer is compatibility and input consistency from browser to browser
Hypothetically, if search landed you on this question then you probably want this:
doReturn(someReturn).when(someObject).doSomething(argThat(argument -> argument.getName().equals("Bob")));
Why? Because like me you value time and you are not going to implement .equals
just for the sake of the single test scenario.
And 99 % of tests fall apart with null returned from Mock and in a reasonable design you would avoid return null
at all costs, use Optional
or move to Kotlin. This implies that verify
does not need to be used that often and ArgumentCaptors are just too tedious to write.

You can connect two iPhones and transfer data via Bluetooth using either the high-level GameKit framework or the lower-level (but still easy to work with) Bonjour discovery mechanisms. Bonjour also works transparently between Bluetooth and WiFi on the iPhone under 3.0, so it's a good choice if you would like to support iPhone-to-iPhone data transfers on those two types of networks.
For more information, you can also look at the responses to these questions:
From the python docs on os.walk()
:
# Delete everything reachable from the directory named in 'top',
# assuming there are no symbolic links.
# CAUTION: This is dangerous! For example, if top == '/', it
# could delete all your disk files.
import os
for root, dirs, files in os.walk(top, topdown=False):
for name in files:
os.remove(os.path.join(root, name))
for name in dirs:
os.rmdir(os.path.join(root, name))
You can also use sqlcmd
mode for this (enable this on the "Query" menu in Management Studio).
:setvar dbname "TEST"
CREATE DATABASE $(dbname)
GO
ALTER DATABASE $(dbname) SET COMPATIBILITY_LEVEL = 90
GO
ALTER DATABASE $(dbname) SET RECOVERY SIMPLE
GO
EDIT:
Check this MSDN article to set parameters via the SQLCMD tool.
Dynamic HTML element functionThe code in here with a little bit of modification and simplification:
<input disabled maxlength="3" size="3" value="10" id="counter">
<textarea onkeyup="textCounter(this,'counter',10);" id="message">
</textarea>
<script>
function textCounter(field,field2,maxlimit)
{
var countfield = document.getElementById(field2);
if ( field.value.length > maxlimit ) {
field.value = field.value.substring( 0, maxlimit );
return false;
} else {
countfield.value = maxlimit - field.value.length;
}
}
</script>
Hope this helps!
tip:
When merging the codes with your page, make sure the HTML elements(textarea
, input
) are loaded first before the scripts (Javascript functions)
The bash script runs in a separate subshell. In order to make this work you will need to source this other script as well.
string
is a string, and string[]
is an array of strings
Adding a PATH definition into the user crontab with correct values will help... I've filled mine with this line on top (after comments, and before cron jobs):
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
And it's enough to get all my scripts working... Include any custom path there if you need to.
You can check if you have any jumper wires plugged into pin 0 and 1. Those pins are used for serial communication and plugged wires can prevent the code from being uploaded on the board.
If nothing is plugged, it might be a bug with AVRDUDE, you can try updating it.
After trying several things, this worked for me:
With addresses other than 0.0.0.0
I had no success.
You should design your table WITHOUT considering the views.
Apart from saving joins and conditions, Views do have a performance advantage: SQL Server may calculate and save its execution plan in the view, and therefore make it faster than "on the fly" SQL statements.
View may also ease your work regarding user access at field level.
It happened to me, and turned out it was because of Charles Proxy.
Charles Proxy is a HTTP debugging proxy server application
Solution (only if you have Charles Proxy installed):
if you are allowed to do it globally then you can set the session time out in

I am using DBLINK to connect internal database for cross database queries.
Reference taken from this article.
Install DbLink extension.
CREATE EXTENSION dblink;
Verify DbLink:
SELECT pg_namespace.nspname, pg_proc.proname
FROM pg_proc, pg_namespace
WHERE pg_proc.pronamespace=pg_namespace.oid
AND pg_proc.proname LIKE '%dblink%';
Test connection of database:
SELECT dblink_connect('host=localhost user=postgres password=enjoy dbname=postgres');
I had this same issue.
The solution for me was found in the Microsoft KB Article 2452723:
Basically, edit your scheduled task and take the Quotes out of the Start In field:
To get the relevant error message:
1) Convert 2147942667 to hex: 8007010B
2) Take last 4 digits (010B) and convert to decimal: 267
3) Run: net helpmsg 267
4) Result: "The directory name is invalid."
I think it's all personal preference. My preferences come from using NHibernate, in .NET, with SQL Server, so they probably differ from what others use.
Honestly, it doesn't matter too much, as long as it's consistent for the project. Just get to work and don't sweat the details :P
Setting the Content-Type header will affect how a web browser treats your content. When most mainstream web browsers encounter a Content-Type of text/plain, they'll render the raw text source in the browser window (as opposed to the source rendered at HTML). It's the difference between seeing
<b>foo</b>
or
foo
Additionally, when using the XMLHttpRequest
object, your Content-Type header will affect how the browser serializes the returned results. Prior to the takeover of AJAX frameworks like jQuery and Prototype, a common problem with AJAX responses was a Content-Type set to text/html instead of text/xml. Similar problems would likely occur if the Content-Type was text/plain.
You can try and define the following macro:
#define for_range(_type, _param, _A1, _B1) for (bool _ok = true; _ok;)\
for (_type _start = _A1, _finish = _B1; _ok;)\
for (int _step = 2*(((int)_finish)>(int)_start)-1;_ok;)\
for (_type _param = _start; _ok ; \
(_param != _finish ? \
_param = static_cast<_type>(((int)_param)+_step) : _ok = false))
Now you can use it:
enum Count { zero, one, two, three };
for_range (Count, c, zero, three)
{
cout << "forward: " << c << endl;
}
It can be used to iterate backwards and forwards through unsigned, integers, enums and chars:
for_range (unsigned, i, 10,0)
{
cout << "backwards i: " << i << endl;
}
for_range (char, c, 'z','a')
{
cout << c << endl;
}
Despite its awkward definition it is optimized very well. I looked at disassembler in VC++. The code is extremely efficient. Don't be put off but the three for statements: the compiler will produce only one loop after optimization! You can even define enclosed loops:
unsigned p[4][5];
for_range (Count, i, zero,three)
for_range(unsigned int, j, 4, 0)
{
p[i][j] = static_cast<unsigned>(i)+j;
}
You obviously cannot iterate through enumerated types with gaps.
The Korn shell, ksh
, offers the whence
built-in, which identifies other shell built-ins, macros, etc. The which
command is more portable, however.
Sorry I've not tested this but I think it's done like this:
var filemap = new System.Configuration.ExeConfigurationFileMap();
System.Configuration.Configuration config = System.Configuration.ConfigurationManager.OpenMappedExeConfiguration(filemap, System.Configuration.ConfigurationUserLevel.None);
//usage: config.AppSettings["xxx"]
This should work:
.panel > .panel-heading {
background-image: none;
background-color: red;
color: white;
}
If your <td>
is not empty, one popular trick is to insert a non breaking space
in it, such that:
<td id="td1"> </td>
Then you will be able to use:
document.getElementById('td1').firstChild.data = 'New Value';
Otherwise, if you do not fancy adding the meaningless  
you can use the solution that Jonathan Fingland described in the other answer.
C++20 offers a new way to achieve this by using std::source_location. This is currently accessible in gcc an clang as std::experimental::source_location
with #include <experimental/source_location>
.
The problem with macros like __LINE__
is that if you want to create for example a logging function that outputs the current line number along with a message, you always have to pass __LINE__
as a function argument, because it is expanded at the call site.
Something like this:
void log(const std::string msg) {
std::cout << __LINE__ << " " << msg << std::endl;
}
Will always output the line of the function declaration and not the line where log
was actually called from.
On the other hand, with std::source_location
you can write something like this:
#include <experimental/source_location>
using std::experimental::source_location;
void log(const std::string msg, const source_location loc = source_location::current())
{
std::cout << loc.line() << " " << msg << std::endl;
}
Here, loc
is initialized with the line number pointing to the location where log
was called.
You can try it online here.
Create the macro as here:
On the Tools menu in Microsoft Excel, point to Macro, and then click Visual Basic Editor. On the Insert menu, click Module. Copy and paste this code into the code window of the module. It will automatically name itself HyperAdd.
Sub HyperAdd()
'Converts each text hyperlink selected into a working hyperlink
For Each xCell In Selection
ActiveSheet.Hyperlinks.Add Anchor:=xCell, Address:=xCell.Formula
Next xCell
End Sub
When you're finished pasting your macro, click Close and Return to Microsoft Excel on the File menu.
Then select the required cells and click macro and click run.
NOTE Do NOT select the whole column! Select ONLY the cells you wish to be changed to clickable links else you will end up in a neverending loop and have to restart Excel! Done!
With postgres 9.3 use -> for object access. 4 example
seed.rb
se = SmartElement.new

SELECT data->'params'->0 as data FROM smart_elements;
returns

(1 row)
You can continue nesting
SELECT data->'params'->0->'type' as data FROM smart_elements;
return

I think another place to look is /var/lib
.
If you go there you can see three mysql folders with 'interesting' permissions:
user group
mysql mysql
Here is what I did to solve my problem with root password:
after running
sudo apt-get purge mysql*
sudo rm -rf /etc/mysql
I also ran the following (instead of my_username put yours):
cd /var/lib
sudo chown --from=mysql <my_username> mysql* -R
sudo rm -rf mysql*
And then:
sudo apt-get install mysql-server
which prompted me to select a new root password. I hope it helps
You could use the map and reduce functions
const arr = [{x:1},{x:2},{x:4}];
const sum = arr.map(n => n.x).reduce((a, b) => a + b, 0);
You could have an extension of this problem in case of your initial text was set into a string type variable, for example:
function status(){
if [ $1 != "stopped" ]; then
artist="ABC";
track="CDE";
album="DEF";
status_message="The current track is $track at $album by $artist";
echo $status_message;
read_status $1 "$status_message";
fi
}
function read_status(){
if [ $1 != "playing" ]; then
echo $2
fi
}
In this case if you don't pass the status_message variable forward as string (surrounded by "") it will be split in a mount of different arguments.
"$variable": The current track is CDE at DEF by ABC
$variable: The
BOOTSTRAP 2 (source)
The problem is that there is no width set on the buttons. Try this:
.btn {width:20%;}
EDIT:
By default the buttons take an auto width of its text length plus some padding, so I guess for your example it is probably more like 14.5% for 5 buttons (to compensate for the padding).
Note:
If you don't want to try and compensate for padding you can use box-sizing:border-box;
You simply have to do:
INSERT INTO def (catid, title, page, publish)
SELECT catid, title, 'page','yes' from `abc`
Here is what I came up with ( and like all Date Time conundrums it is probably going to be disproved based on some weird timezone-leapyear-daylight adjustment :D )
Date
<<->> LocalDateTime
Given: Date date = [some date]
(1) LocalDateTime
<< Instant
<< Date
Instant instant = Instant.ofEpochMilli(date.getTime());
LocalDateTime ldt = LocalDateTime.ofInstant(instant, ZoneOffset.UTC);
(2) Date
<< Instant
<< LocalDateTime
Instant instant = ldt.toInstant(ZoneOffset.UTC);
Date date = Date.from(instant);
Example:
Date date = new Date();
System.out.println(date + " long: " + date.getTime());
LocalDateTime
<< Instant
<< Date
:Create Instant
from Date
:
Instant instant = Instant.ofEpochMilli(date.getTime());
System.out.println("Instant from Date:\n" + instant);
Create Date
from Instant
(not necessary,but for illustration):
date = Date.from(instant);
System.out.println("Date from Instant:\n" + date + " long: " + date.getTime());
Create LocalDateTime
from Instant
LocalDateTime ldt = LocalDateTime.ofInstant(instant, ZoneOffset.UTC);
System.out.println("LocalDateTime from Instant:\n" + ldt);
Date
<< Instant
<< LocalDateTime
Create Instant
from LocalDateTime
:
instant = ldt.toInstant(ZoneOffset.UTC);
System.out.println("Instant from LocalDateTime:\n" + instant);
Create Date
from Instant
:
date = Date.from(instant);
System.out.println("Date from Instant:\n" + date + " long: " + date.getTime());

Man, try the min-height.
.div1 {
float: left;
height: 100%;
min-height: 100%;
width: 25%;
}
.div2 {
float: left;
height: 100%;
min-height: 100%;
width: 75%;
}
you can use CSharpProvider:
var code = @"
public class Abc {
public string Get() { return ""abc""; }
}
";
var options = new CompilerParameters();
options.GenerateExecutable = false;
options.GenerateInMemory = false;
var provider = new CSharpCodeProvider();
var compile = provider.CompileAssemblyFromSource(options, code);
var type = compile.CompiledAssembly.GetType("Abc");
var abc = Activator.CreateInstance(type);
var method = type.GetMethod("Get");
var result = method.Invoke(abc, null);
Console.WriteLine(result); //output: abc
You may be able to adapt a version of the C++ virtual constructor idiom. As far as I know, C# doesn't support covariant return types. I believe that's on many peoples' wish lists.
set the first element to NULL. printing the char array will give you nothing back.
for Google Maps v3, you need to trigger the resize event differently:
google.maps.event.trigger(map, "resize");
See the documentation for the resize event (you'll need to search for the word 'resize'): http://code.google.com/apis/maps/documentation/v3/reference.html#event
Update
This answer has been here a long time, so a little demo might be worthwhile & although it uses jQuery, there's no real need to do so.
$(function() {
var mapOptions = {
zoom: 8,
center: new google.maps.LatLng(-34.397, 150.644)
};
var map = new google.maps.Map($("#map-canvas")[0], mapOptions);
// listen for the window resize event & trigger Google Maps to update too
$(window).resize(function() {
// (the 'map' here is the result of the created 'var map = ...' above)
google.maps.event.trigger(map, "resize");
});
});

UPDATE 2018-05-22
With a new renderer release in version 3.32 of Maps JavaScript API the resize event is no longer a part of Map
class.
The documentation states
When the map is resized, the map center is fixed
The full-screen control now preserves center.
There is no longer any need to trigger the resize event manually.
source: https://developers.google.com/maps/documentation/javascript/new-renderer
google.maps.event.trigger(map, "resize");
doesn't have any effect starting from version 3.32
I had a similar bug, but while using a fixed number for height and not a percentage. It was also a flex container within the body (which has no specified height). It appeared that on Safari, my flex container had a height of 9px for some reason, but in all other browsers it displayed the correct 100px height specified in the stylesheet.
I managed to get it to work by adding both the height
and min-height
properties to the CSS class.
The following worked for me on both Safari 13.0.4 and Chrome 79.0.3945.130:
.flex-container {
display: flex;
flex-direction: column;
min-height: 100px;
height: 100px;
}
Hope this helps!
I did this once in a postgres app by running:
EXPLAIN SELECT * FROM foo;
Then examining the output with a regex, or similar logic. For a simple SELECT *, the first line of output should look something like this:
Seq Scan on uids (cost=0.00..1.21 rows=8 width=75)
You can use the rows=(\d+)
value as a rough estimate of the number of rows that would be returned, then only do the actual SELECT COUNT(*)
if the estimate is, say, less than 1.5x your threshold (or whatever number you deem makes sense for your application).
Depending on the complexity of your query, this number may become less and less accurate. In fact, in my application, as we added joins and complex conditions, it became so inaccurate it was completely worthless, even to know how within a power of 100 how many rows we'd have returned, so we had to abandon that strategy.
But if your query is simple enough that Pg can predict within some reasonable margin of error how many rows it will return, it may work for you.
To run multiple commands just add &&
between two commands like this: command1 && command2
And if you want to run them in two different terminals then you do it like this:
gnome-terminal -e "command1" && gnome-terminal -e "command2"
This will open 2 terminals with command1
and command2
executing in them.
Hope this helps you.
First up, you seem to be mixing table variables and tables.
Either way, You can't pass in the table's name like that. You would have to use dynamic TSQL to do that.
If you just want to declare a table variable:
CREATE PROC sp_createATable
@name VARCHAR(10),
@properties VARCHAR(500)
AS
declare @tablename TABLE
(
id CHAR(10) PRIMARY KEY
);
The fact that you want to create a stored procedure to dynamically create tables might suggest your design is wrong.
git show somebranch:path/to/your/file
you can also do multiple files and have them concatenated:
git show branchA~10:fileA branchB^^:fileB
You do not have to provide the full path to the file, relative paths are acceptable e.g.:
git show branchA~10:../src/hello.c
If you want to get the file in the local directory (revert just one file) you can checkout:
git checkout somebranch^^^ -- path/to/file
When I tried to create something simillar to inbox floating action button i thought about creating own custom component.
It would be simple frame layout with fixed height (to contain expanded menu) containing FAB button and 3 more placed under the FAB. when you click on FAB you just simply animate other buttons to translate up from under the FAB.
There are some libraries which do that (for example https://github.com/futuresimple/android-floating-action-button), but it's always more fun if you create it by yourself :)
I think you could call the id, like this
{% for days in days_list %}
<h2># Day {{ days.id }} - From {{ days.from_location }} to {{ days.to_location }}</h2>
{% endfor %}
PYTHONPATH ends up in sys.path, which you can modify at runtime.
import sys
sys.path += ["whatever"]
In the new alpha versions they've introduced utility spacing classes. The structure can then be tweaked if you use them in a clever way.
Spacing utility classes
<div class="container-fluid">
<div class="row">
<div class="col-sm-4 col-md-3 pl-0">…</div>
<div class="col-sm-4 col-md-3">…</div>
<div class="col-sm-4 col-md-3">…</div>
<div class="col-sm-4 col-md-3 pr-0">…</div>
</div>
</div>
pl-0
and pr-0
will remove leading and trailing padding from the columns.
One issue left is the embedded rows of a column, as they still have negative margin. In this case:
<div class="col-sm-12 col-md-6 pl-0">
<div class="row ml-0">
</div>
Version differences
Also note the utility spacing classes were changed since version 4.0.0-alpha.4
.
Before they were separated by 2 dashes e.g. => p-x-0
and p-l-0
and so on ...
To stay on topic for the version 3: This is what I use on Bootstrap 3 projects and include the compass setup, for this particular spacing utility, into bootstrap-sass
(version 3) or bootstrap
(version 4.0.0-alpha.3) with double dashes or bootstrap
(version 4.0.0-alpha.4 and up) with single dashes.
Also, latest version(s) go up 'till 5 times a ratio (ex: pt-5
padding-top 5) instead of only 3.
Compass
$grid-breakpoints: (xs: 0, sm: 576px, md: 768px, lg: 992px, xl: 1200px) !default;
@import "../scss/mixins/breakpoints"; // media-breakpoint-up, breakpoint-infix
@import "../scss/utilities/_spacing.scss";
CSS output
You can ofcourse always copy/paste the padding spacing classes only from a generated css file.

You can't specify the size of the array within the generic parameter, only add arrays of specific size to the list later. This also means that the compiler can't guarantee that all sub-arrays be of the same size, it must be ensured by you.
A better solution might be to encapsulate this within a class, where you can ensure the uniform size of the arrays as a type invariant.
I think that concat
method and +
should be mentioned here as well:
assert_eq!(
("My".to_owned() + " " + "string"),
["My", " ", "string"].concat()
);
and there is also concat!
macro but only for literals:
let s = concat!("test", 10, 'b', true);
assert_eq!(s, "test10btrue");
Give this a try:
PS> $nl = [Environment]::NewLine
PS> gci hklm:\software\microsoft\windows\currentversion\uninstall |
ForEach { $_.GetValue("DisplayName") } | Where {$_} | Sort |
Foreach {"$_$nl"} | Out-File addrem.txt -Enc ascii
It yields the following text in my addrem.txt file:
Adobe AIR
Adobe Flash Player 10 ActiveX
...
Note: on my system, GetValue("DisplayName") returns null for some entries, so I filter those out. BTW, you were close with this:
ForEach-Object -Process { "$_.GetValue("DisplayName") `n" }
Except that within a string, if you need to access a property of a variable, that is, "evaluate an expression", then you need to use subexpression syntax like so:
Foreach-Object -Process { "$($_.GetValue('DisplayName'))`r`n" }
Essentially within a double quoted string PowerShell will expand variables like $_
, but it won't evaluate expressions unless you put the expression within a subexpression using this syntax:
$(`<Multiple statements can go in here`>).
You can use str()
to cast it, or formatters:
"ME%d.txt" % (num,)
This is my working code. you may try with this.

For number input or numeric keyboard you can use keyboardType: TextInputType.number
TextFormField(
decoration: InputDecoration(labelText:'Amount'),
controller: TextEditingController(
),
validator: (value) {
if (value.isEmpty) {
return 'Enter Amount';
}
},
keyboardType: TextInputType.number
)
No, there is no way to access the element by index in JavaScript objects.
One solution to this if you have access to the source of this JSON, would be to change each element to a JSON object and stick the key inside of that object like this:
var obj = [
{"key":"set1", "data":[1, 2, 3]},
{"key":"set2", "data":[4, 5, 6, 7, 8]},
{"key":"set3", "data":[9, 10, 11, 12]}
];
You would then be able to access the elements numerically:
for(var i = 0; i < obj.length; i++) {
var k = obj[i]['key'];
var data = obj[i]['data'];
//do something with k or data...
}

we can use Model.last(5)
or Model.limit(5).order(id: :desc)

cbar.ax.set_ylabel('# of contacts', rotation=270)
# put the major ticks at the middle of each cell
ax.set_xticks(np.arange(data.shape[1]) + 0.5, minor=False)

You were very close. Once you have a reference to the color bar axis, you can do what ever you want to it, including putting text labels in the middle. You might want to play with the formatting to make it more visible.
Simply do this
var key = "keyOne";
var obj = {};
obj[key] = someValue;
If you are looking for a method to filter an array by a string occurring in keys, you can use:
$mArray=array('foo'=>'bar','foo2'=>'bar2','fooToo'=>'bar3','baz'=>'nope');
$mSearch='foo';
$allowed=array_filter(
array_keys($mArray),
function($key) use ($mSearch){
return stristr($key,$mSearch);
});
$mResult=array_intersect_key($mArray,array_flip($allowed));
The result of print_r($mResult)
is
Array ( [foo] => bar [foo2] => bar2 [fooToo] => bar3 )
An adaption of this answer that supports regular expressions
function array_preg_filter_keys($arr, $regexp) {
$keys = array_keys($arr);
$match = array_filter($keys, function($k) use($regexp) {
return preg_match($regexp, $k) === 1;
});
return array_intersect_key($arr, array_flip($match));
}
$mArray = array('foo'=>'yes', 'foo2'=>'yes', 'FooToo'=>'yes', 'baz'=>'nope');
print_r(array_preg_filter_keys($mArray, "/^foo/i"));
Output
Array
(
[foo] => yes
[foo2] => yes
[FooToo] => yes
)
Use This its is very useful for your solution:
Yes you can do this. RelativeLayout, LinearLayout, etc are Views so a custom layout is a custom view. Just something to consider because if you wanted to create a custom layout you could.
What you want to do is create a Compound Control. You'll create a subclass of RelativeLayout, add all our your components in code (TextView, etc), and in your constructor you can read the attributes passed in from the XML. You can then pass that attribute to your title TextView.
http://developer.android.com/guide/topics/ui/custom-components.html
using (DataContext dc = new DataContext())
{
var q = from t in dc.TableTests
group t by t.SerialNumber
into g
select new
{
SerialNumber = g.Key,
uid = (from t2 in g select t2.uid).Max()
};
}
Say this is your xml with spinner entries (ie. titles) and values:
<resources>
<string-array name="size_entries">
<item>Small</item>
<item>Medium</item>
<item>Large</item>
</string-array>
<string-array name="size_values">
<item>12</item>
<item>16</item>
<item>20</item>
</string-array>
</resources>
and this is your spinner:
<Spinner
android:id="@+id/size_spinner"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:entries="@array/size_entries" />
Then in your code to get the entries:
Spinner spinner = (Spinner) findViewById(R.id.size_spinner);
String size = spinner.getSelectedItem().toString(); // Small, Medium, Large
and to get the values:
int spinner_pos = spinner.getSelectedItemPosition();
String[] size_values = getResources().getStringArray(R.array.size_values);
int size = Integer.valueOf(size_values[spinner_pos]); // 12, 16, 20
Update: you can read the more complex answer, which contains more methods and information.
There exists a couple of scripts, which can be used as simple package managers. But as far as I know, none of them allows you to upgrade packages, because it’s not an easy task on Windows since there is not possible to overwrite files in use. So you have to close all Cygwin instances first and then you can use Cygwin’s native setup.exe (which itself does the upgrade via “replace after reboot” method, when files are in use).
The best one for me. Simply because it’s one of the most recent. It works correctly for both platforms - x86 and x86_64. There exists a lot of forks with some additional features. For example the kou1okada fork is one of improved versions.
It has also command line mode. Moreover it allows you to upgrade all installed packages at once.
setup.exe-x86_64.exe -q --packages=bash,vim
Example use:
setup.exe-x86_64.exe -q --packages="bash,vim"
You can create an alias for easier use, for example:
alias cyg-get="/cygdrive/d/path/to/cygwin/setup-x86_64.exe -q -P"
Then you can for example install the Vim package with:
cyg-get vim
These days, you can leverage the .NET library from VBA. The following works for me in Excel 2016. Returns the hash as uppercase hex.
Public Function SHA1(ByVal s As String) As String
Dim Enc As Object, Prov As Object
Dim Hash() As Byte, i As Integer
Set Enc = CreateObject("System.Text.UTF8Encoding")
Set Prov = CreateObject("System.Security.Cryptography.SHA1CryptoServiceProvider")
Hash = Prov.ComputeHash_2(Enc.GetBytes_4(s))
SHA1 = ""
For i = LBound(Hash) To UBound(Hash)
SHA1 = SHA1 & Hex(Hash(i) \ 16) & Hex(Hash(i) Mod 16)
Next
End Function

I think the easiest way to do such thing is to resolve the routes later, you could ask the routes via json, for example. Check out that I make a factory out of the $routeProvider during config phase, via $provide, so I can keep using the $routeProvider object in the run phase, and even in controllers.
'use strict';
angular.module('myapp', []).config(function($provide, $routeProvider) {
$provide.factory('$routeProvider', function () {
return $routeProvider;
});
}).run(function($routeProvider, $http) {
$routeProvider.when('/', {
templateUrl: 'views/main.html',
controller: 'MainCtrl'
}).otherwise({
redirectTo: '/'
});
$http.get('/dynamic-routes.json').success(function(data) {
$routeProvider.when('/', {
templateUrl: 'views/main.html',
controller: 'MainCtrl'
});
// you might need to call $route.reload() if the route changed
$route.reload();
});
});
You need some sort of Inter Process Communication. Use a pipe or a shared buffer.
In general you just have to define a slightly transparent color when creating the shape.
You can achieve that by setting the colors alpha channel.
#FF000000
will get you a solid black whereas #00000000
will get you a 100% transparent black (well it isn't black anymore obviously).
The color scheme is like this #AARRGGBB
there A stands for alpha channel, R stands for red, G for green and B for blue.
The same thing applies if you set the color in Java. There it will only look like 0xFF000000
.
UPDATE
In your case you'd have to add a solid
node. Like below.
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/shape_my">
<stroke android:width="4dp" android:color="#636161" />
<padding android:left="20dp"
android:top="20dp"
android:right="20dp"
android:bottom="20dp" />
<corners android:radius="24dp" />
<solid android:color="#88000000" />
</shape>
The color here is a half transparent black.
For Windows, javac
should be a command that you can run from anywhere. If it isn't (which is strange in and of itself), you need to run javac
from where it's located, but navigate to the exact location of your Java class file in order to compile it successfully.
By default, javac
will compile a file name relative to the current path, and if it can't find the file, it won't compile it.
Please note: You would only be able to use jdk1.8.0 to actually compile, since that would be the only library set that has javac
contained in it. Remember: the Java Runtime Environment runs Java classes; the Java Development Kit compiles them.
Check with following css. Demo
.circle {
width: 140px;
height: 140px;
background: red;
-moz-border-radius: 70px;
-webkit-border-radius: 70px;
border-radius: 70px;
}
For more shapes you can follow following urls:
You should really use for()
instead of foreach()
in this case.
In my case, the problem turned out to be that the keyfile was behind a 301 Moved Permanently redirect, which the curl command failed to follow. I fixed it by using wget
instead:
wget URL
sudo apt-key add FILENAME
...where FILENAME is the file name that wget
outputs after it downloads the file.
Update: Alternatively, you can use curl -L
to make curl follow redirects.
If you would want to change the logging level of all the loggers use the below method. This will enumerate over all the loggers and change the logging level to given level. Please make sure that you DO NOT have log4j.appender.loggerName.Threshold=DEBUG
property set in your log4j.properties
file.
public static void changeLogLevel(Level level) {
Enumeration<?> loggers = LogManager.getCurrentLoggers();
while(loggers.hasMoreElements()) {
Logger logger = (Logger) loggers.nextElement();
logger.setLevel(level);
}
}
Interesting enough, this error also occurs, at time of opening when the .XLS?
file is incorrectly formed or require repairs.
A hard to find error is to many rows on a .xls (old excel) file.
Test it: manually open the affected file with excel desktop .
I use automation to process a few hundred files daily, when this error show up, I notify the owner via mail and save the unprocessed file on a temporary location.
input_str = "ABC"
[bin(byte) for byte in bytes(input_str, "utf-8")]
Will give:
['0b1000001', '0b1000010', '0b1000011']
The pseudo-elements generated by ::before and ::after are contained by the element's formatting box, and thus don't apply to replaced elements such as img, or to br elements.

You probably didn't declare your module correctly, or you put the function before the module is declared (safe rule is to put angular module after the body, once all the page is loaded). Since you're using angularjs, then you should use $interval (angularjs equivalence to setInterval which is a windows service).
Here is a working solution:
angular.module('count', [])_x000D_
.controller('countController', function($scope, $interval) {_x000D_
$scope.countDown = 10;_x000D_
$interval(function() {_x000D_
console.log($scope.countDown--);_x000D_
}, 1000, $scope.countDown);_x000D_
});
_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.7.1/angular.min.js"></script>_x000D_
_x000D_
_x000D_
<body>_x000D_
<div ng-app="count" ng-controller="countController"> {{countDown}} </div>_x000D_
</body>
_x000D_
Note: it stops at 0 in the html view, but at 1 in the console.log, can you figure out why? ;)
You are probably connecting fine but don't have sufficient privileges to run show dbs
.
You don't need to run the db.auth if you pass the auth in the command line:
mongo somewhere.mongolayer.com:10011/my_database -u username -p password
Once you connect are you able to see collections?
> show collections
If so all is well and you just don't have admin privileges to the database and can't run the show dbs
You could also use Hex Color Code,
Name Hex Color Code RGB Color Code
Red #FF0000 rgb(255, 0, 0)
Maroon #800000 rgb(128, 0, 0)
Yellow #FFFF00 rgb(255, 255, 0)
Olive #808000 rgb(128, 128, 0)
For example
import matplotlib.pyplot as plt
import random
number_of_colors = 8
color = ["#"+''.join([random.choice('0123456789ABCDEF') for j in range(6)])
for i in range(number_of_colors)]
print(color)
['#C7980A', '#F4651F', '#82D8A7', '#CC3A05', '#575E76', '#156943', '#0BD055', '#ACD338']
Lets try plotting them in a scatter plot
for i in range(number_of_colors):
plt.scatter(random.randint(0, 10), random.randint(0,10), c=color[i], s=200)
plt.show()

start_time = time.time()

PROF_DATA = {}
def profile(fn):
@wraps(fn)
def with_profiling(*args, **kwargs):
start_time = time.time()
ret = fn(*args, **kwargs)
elapsed_time = time.time() - start_time
if fn.__name__ not in PROF_DATA:
PROF_DATA[fn.__name__] = [0, []]
PROF_DATA[fn.__name__][0] += 1
PROF_DATA[fn.__name__][1].append(elapsed_time)
return ret
return with_profiling
def print_prof_data():
for fname, data in PROF_DATA.items():
max_time = max(data[1])
avg_time = sum(data[1]) / len(data[1])

If you are doing a lot of functionality based on scroll position, Scroll magic (http://scrollmagic.io/) is built entirely for this purpose.
It makes it easy to trigger JS based on when the user reaches certain elements when scrolling. It also integrates with the GSAP animation engine (https://greensock.com/) which is great for parallax scrolling websites
jQuery
if( ['class', 'class2'].some(c => [...element[0].classList].includes(c)) )
Vanilla JS
if( ['class', 'class2'].some(c => [...element.classList].includes(c)) )
I finally went for a similar solution to the one that Sascha provided, however with some little adjusting, since I'm setting the cookies explicitly in PHP:
// excecute this code if user has not authorized the application yet
// $facebook object must have been created before
$accessToken = $_COOKIE['access_token']
if ( empty($accessToken) && strpos($_SERVER['HTTP_USER_AGENT'], 'Safari') ) {
$accessToken = $facebook->getAccessToken();
$redirectUri = 'https://URL_WHERE_APP_IS_LOCATED?access_token=' . $accessToken;
} else {
$redirectUri = 'https://apps.facebook.com/APP_NAMESPACE/';
}
// generate link to auth dialog
$linkToOauthDialog = $facebook->getLoginUrl(
array(
'scope' => SCOPE_PARAMS,
'redirect_uri' => $redirectUri
)
);
echo '<script>window.top.location.href="' . $linkToOauthDialog . '";</script>';
What this does is check if the cookie is available when the browser is safari. In the next step, we are on the application domain, namely the URI provided as URL_WHERE_APP_IS_LOCATED above.
if (isset($_GET['accessToken'])) {
// cookie has a lifetime of only 10 seconds, so that after
// authorization it will disappear
setcookie("access_token", $_GET['accessToken'], 10);
} else {
// depending on your application specific requirements
// redirect, call or execute authorization code again
// with the cookie now set, this should return FB Graph results
}
So after being redirecting to the application domain, a cookie is set explicitly, and I redirect the user to the authorization process.
In my case (since I'm using CakePHP but it should work fine with any other MVC framework) I'm calling the login action again where the FB authorization is executed another time, and this time it succeeds due to the existing cookie.
After having authorized the app once, I didn't have any more problems using the app with Safari (5.1.6)
Hope that might help anyone.
With ES6 you can do it very short:
options.filter(opt => !opt.assigned).map(opt => someNewObject)
If you want just a first selected row, you can:
select fname from MyTbl where rownum = 1
You can also use analytic functions to order and take the top x:
select max(fname) over (rank() order by some_factor) from MyTbl
@Override
public boolean onTouch(View v, MotionEvent event) {
float x = event.getX();
float y = event.getY();
return true;
}
Robocopy, or "Robust File Copy", is a command-line directory and/or file replication command. Robocopy functionally replaces Xcopy, with more options. It has been available as part of the Windows Resource Kit starting with Windows NT 4.0, and was first introduced as a standard feature in Windows Vista and Windows Server 2008. The command is
robocopy
...
You can use the HttpWebRequest class to do so.
Example here:
using System;
using System.Net;
using System.Text;
using System.IO;
public class Test
{
// Specify the URL to receive the request.
public static void Main (string[] args)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create (args[0]);
// Set some reasonable limits on resources used by this request
request.MaximumAutomaticRedirections = 4;
request.MaximumResponseHeadersLength = 4;
// Set credentials to use for this request.
request.Credentials = CredentialCache.DefaultCredentials;
HttpWebResponse response = (HttpWebResponse)request.GetResponse ();
Console.WriteLine ("Content length is {0}", response.ContentLength);
Console.WriteLine ("Content type is {0}", response.ContentType);
// Get the stream associated with the response.
Stream receiveStream = response.GetResponseStream ();
// Pipes the stream to a higher level stream reader with the required encoding format.
StreamReader readStream = new StreamReader (receiveStream, Encoding.UTF8);
Console.WriteLine ("Response stream received.");
Console.WriteLine (readStream.ReadToEnd ());
response.Close ();
readStream.Close ();
}
}
/*
The output from this example will vary depending on the value passed into Main
but will be similar to the following:
Content length is 1542
Content type is text/html; charset=utf-8
Response stream received.
<html>
...
</html>

METHOD 1: I deleted the androidTestCompile on espresso-core line which was automatically included in a new project. Then my Android Studio compiles clean.
The androidTestCompile is in "build.gradle (Module:app)":
dependencies {
...
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
...
}
I don't know whether this deletion will have any problem down the road, but it surely works for my current project now.
METHOD 2: Adding an exclude on findbugs works too:
dependencies {
...
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
exclude group: 'com.google.code.findbugs'
})
...
}
METHOD 3: Forcing compiling with a specific version:
(In the following I force it to compile with the higher version.)
dependencies {
...
androidTestCompile 'com.google.code.findbugs:jsr305:3.0.0'
...
}
You can try Dummynet, it can simulates queue and bandwidth limitations, delays, packet losses, and multipath effects
For some databases, you can just explicitly insert a NULL
into the auto_increment
column:
INSERT INTO table_name VALUES (NULL, 'my name', 'my group')
There are two properties in a TabControl control that manages which tab page is selected.
SelectedIndex which offer the possibility to select it by index (an integer starting from 0 to the number of tabs you have minus one).
SelectedTab which offer the possibility to selected the tab object itself to select.
Setting either of these property will change the currently displayed tab.
Alternatively you can also use the Select method. It comes in three flavour, one where you pass the index of the tab, another the TabPage object itself and the last one a string representing the tab's name.
A postback is the process of re-loading a page, so if you want the page to close after the postback then you need to set your window.close() javascript to run with the browser's onload event during that postback, normally done using the ClientScript.RegisterStartupScript()
function.
But are you sure this is what you want to do? Closing pages tends to piss off users.
because you have set index is 0 it shows always 1st value from combobox as input.
Try this :
With Me.ComboBox1
.DropDownStyle = ComboBoxStyle.DropDown
.Text = " "
End With
it just simple :import this directory
import {Component, Directive, Input, ViewChild} from '@angular/core';
Try this code
Bitmap bmp = new Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height);
Graphics gr = Graphics.FromImage(bmp);
gr.CopyFromScreen(0, 0, 0, 0, bmp.Size);
pictureBox1.Image = bmp;
bmp.Save("img.png",System.Drawing.Imaging.ImageFormat.Png);
Don't forget that all your old console utilities work just fine in PowerShell:
PS> hostname
KEITH1
In case you don't have Linq, I solved it the following way:
private T[] GetArray<T>(IList<T> iList) where T: new()
{
var result = new T[iList.Count];
iList.CopyTo(result, 0);
return result;
}
Hope it helps
The code should instead be something like this:
TextView text = (TextView) findViewById(R.id.this_is_the_id_of_textview);
text.setText("test");

Angular CLI 1.7 introduced ng update
.
ng update
A new Angular CLI command to help simplify keeping your projects up to date with the latest versions. Packages can define logic which will be applied to your projects to ensure usage of latest features as well as making changes to reduce or eliminate the impact related to breaking changes.
Configuration information for ng update can be found here
1.7 to 6 update
CLI 1.7 does not support an automatic v6 update. Manually install @angular/cli via your package manager, then run the update migration schematic to finish the process.
npm install @angular/cli@^6.0.0
ng update @angular/cli --migrate-only --from=1
UPDATED 30/04/2017:
1.0 Update
You should now follow the Angular CLI migration guide
UPDATED 04/03/2017:
RC Update
You should follow the Angular CLI RC migration guide
UPDATED 20/02/2017:
Please be aware 1.0.0-beta.32 has breaking changes and has removed ng init and ng update
The pull request here states the following:
BREAKING CHANGE: Removing the ng init & ng update commands because their current implementation causes more problems than it solves. Update functionality will return to the CLI, until then manual updates of applications will need done.
The angular-cli CHANGELOG.md states the following:
BREAKING CHANGES - @angular/cli: Removing the ng init & ng update commands because their current implementation causes more problems than it solves. Once RC is released, we won't need to use those to update anymore as the step will be as simple as installing the latest version of the CLI.
UPDATED 17/02/2017:
Angular-cli has now been added to the NPM @angular package. You should now replace the above command with the following -
Global package:
npm uninstall -g angular-cli @angular/cli
npm cache clean
npm install -g @angular/cli@latest
Local project package:
rm -rf node_modules dist # On Windows use rmdir /s /q node_modules dist
npm install --save-dev @angular/cli@latest
npm install
ng init
ORIGINAL ANSWER
You should follow the steps from the README.md on GitHub for updating angular via the angular-cli.
Here they are:
Updating angular-cli
To update angular-cli to a new version, you must update both the global package and your project's local package.
Global package:
npm uninstall -g angular-cli
npm cache clean
npm install -g angular-cli@latest
Local project package:
rm -rf node_modules dist tmp # On Windows use rmdir /s /q node_modules dist tmp
npm install --save-dev angular-cli@latest
npm install
ng init
Running ng init
will check for changes in all the auto-generated files created by ng new and allow you to update yours. You are offered four choices for each changed file: y (overwrite), n (don't overwrite), d (show diff between your file and the updated file) and h (help).
Carefully read the diffs for each code file, and either accept the changes or incorporate them manually after ng init finishes.
