Just Run MySQL Server Installer and Reconfigure the My SQL Server...This worked for me.
Simple Steps
Microsoft recently open sourced their jdbc driver.
You can now find the driver on maven central:
<!-- https://mvnrepository.com/artifact/com.microsoft.sqlserver/mssql-jdbc -->
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>mssql-jdbc</artifactId>
<version>6.1.0.jre8</version>
</dependency>
or for java 7:
<!-- https://mvnrepository.com/artifact/com.microsoft.sqlserver/mssql-jdbc -->
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>mssql-jdbc</artifactId>
<version>6.1.0.jre7</version>
</dependency>
Right click your project--->Build path---->configure Build path----> Libraries Tab--->Add External jars--->(Navigate to the location where you have kept the sql driver jar)--->ok
You need to set a -D system property called java.library.path
that points at the directory containing the sqljdbc_auth.dll
.
The javax.servlet dependency is missing in your pom.xml. Add the following to the dependencies-Node:
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.0.1</version>
<scope>provided</scope>
</dependency>
I've just encountered the same problem but within my own application. I didn't like the solution with copying the dll since it's not very convenient so I did some research and came up with the following programmatic solution.
Basically, before doing any connections to SQL server, you have to add the sqljdbc_auth.dll
to path.. which is easy to say:
PathHelper.appendToPath("C:\\sqljdbc_6.2\\enu\\auth\\x64");
once you know how to do it:
import java.lang.reflect.Field;
public class PathHelper {
public static void appendToPath(String dir){
String path = System.getProperty("java.library.path");
path = dir + ";" + path;
System.setProperty("java.library.path", path);
try {
final Field sysPathsField = ClassLoader.class.getDeclaredField("sys_paths");
sysPathsField.setAccessible(true);
sysPathsField.set(null, null);
}
catch (Exception ex){
throw new RuntimeException(ex);
}
}
}
Now integration authentication works like a charm :).
Credits to https://stackoverflow.com/a/21730111/1734640 for letting me figure this out.
Your URL should be jdbc:sqlserver://server:port;DatabaseName=dbname
and Class name should be like com.microsoft.sqlserver.jdbc.SQLServerDriver
Use MicrosoftSQL Server JDBC Driver 2.0
Indeed. The thing is that the 2008 R2 version is very tricky. The JTDs driver seems to work on some cases. In a certain server, the jTDS worked fine for an 2008 R2 instance. In another server, though, I had to use Microsoft's JBDC driver sqljdbc4.jar. But then, it would only work after setting the JRE environment to 1.6(or higher).
I used 1.5 for the other server, so I waisted a lot of time on this.
Tricky issue.
You can try the following. Works fine in my case:
Hope that helps.

Create a file, date.bat
:
@echo off
For /f "tokens=2-4 delims=/ " %%a in ('date /t') do (set mydate=%%c-%%a-%%b)
For /f "tokens=1-3 delims=/:/ " %%a in ('time /t') do (set mytime=%%a-%%b-%%c)
set mytime=%mytime: =%
echo %mydate%_%mytime%
Run date.bat

UPDATE:
You can also do it with one line like this:
for /f "tokens=2-8 delims=.:/ " %%a in ("%date% %time%") do set DateNtime=%%c-%%a-%%b_%%d-%%e-%%f.%%g
here another option:

PS II> $f.split('\')[-1] -replace '\.\w+$'
PS II> $f.Substring(0,$f.LastIndexOf('.')).split('\')[-1]
Makefile.am
is a programmer-defined file and is used by automake
to generate the Makefile.in
file (the .am
stands for automake).
The configure
script typically seen in source tarballs will use the Makefile.in
to generate a Makefile
.
The configure
script itself is generated from a programmer-defined file named either configure.ac
or configure.in
(deprecated). I prefer .ac
(for autoconf) since it differentiates it from the generated Makefile.in
files and that way I can have rules such as make dist-clean
which runs rm -f *.in
. Since it is a generated file, it is not typically stored in a revision system such as Git, SVN, Mercurial or CVS, rather the .ac
file would be.

Read about make
and Makefile
first, then learn about automake
, autoconf
, libtool
, etc.

It looks like the Django REST framework uses the HTTP accept header in a Request in order to automatically determine which renderer to use:
http://www.django-rest-framework.org/api-guide/renderers/
Using the HTTP accept header may provide an alternative source for your "if something".
From the documentation:
Warning: Starting from Android Build.VERSION_CODES#R, for apps targeting API level Build.VERSION_CODES#R or higher, this method (setGravity) is a no-op when called on text toasts.
Which means that setGravity
can no longer be used in API 30+ and will have to find another to achieve the required behaviour.
I wrote a tool to capture images from a webcam entirely in Python, based on DirectShow. You can find it here: https://github.com/andreaschiavinato/python_grabber.
You can use the whole application or just the class FilterGraph in dshow_graph.py in the following way:
from pygrabber.dshow_graph import FilterGraph
import numpy as np
from matplotlib.image import imsave
graph = FilterGraph()
print(graph.get_input_devices())
device_index = input("Enter device number: ")
graph.add_input_device(int(device_index))
graph.display_format_dialog()
filename = r"c:\temp\imm.png"
# np.flip(image, axis=2) required to convert image from BGR to RGB
graph.add_sample_grabber(lambda image : imsave(filename, np.flip(image, axis=2)))
graph.add_null_render()
graph.prepare()
graph.run()
x = input("Press key to grab photo")
graph.grab_frame()
x = input(f"File {filename} saved. Press key to end")
graph.stop()
If is ok for you to index the array you can do this:
<form>
<input type="text" class="form-control" placeholder="Titel" name="levels[0][level]">
<input type="text" class="form-control" placeholder="Titel" name="levels[0][build_time]">
<input type="text" class="form-control" placeholder="Titel" name="levels[1][level]">
<input type="text" class="form-control" placeholder="Titel" name="levels[1][build_time]">
<input type="text" class="form-control" placeholder="Titel" name="levels[2][level]">
<input type="text" class="form-control" placeholder="Titel" name="levels[2][build_time]">
</form>
... to achieve that:
[levels] => Array (
[0] => Array (
[level] => 1
[build_time] => 2
)
[1] => Array (
[level] => 234
[build_time] => 456
)
[2] => Array (
[level] => 111
[build_time] => 222
)
)
But if you remove one pair of inputs (dynamically, I suppose) from the middle of the form then you'll get holes in your array, unless you update the input names...
This should do it:
private enum Alignment { LEFT, RIGHT };
String drawCellValue (int maxCellLength, String cellValue, Alignment align){
if (align == Alignment.LEFT)
{
//Process it...
}
}
Another approach is to not have the secret on the device in the first place! See Mobile API Security Techniques (especially part 3).
Using the time honored tradition of indirection, share the secret between your API endpoint and an app authentication service.
When your client wants to make an API call, it asks the app auth service to authenticate it (using strong remote attestation techniques), and it receives a time limited (usually JWT) token signed by the secret.
The token is sent with each API call where the endpoint can verify its signature before acting on the request.
The actual secret is never present on the device; in fact, the app never has any idea if it is valid or not, it juts requests authentication and passes on the resulting token. As a nice benefit from indirection, if you ever want to change the secret, you can do so without requiring users to update their installed apps.
So if you want to protect your secret, not having it in your app in the first place is a pretty good way to go.
Avoid non-standard compiler extensions and implement it as a completely type-safe macro in pure standard C (ISO 9899:2011).
Solution
#define GENERIC_MAX(x, y) ((x) > (y) ? (x) : (y))
#define ENSURE_int(i) _Generic((i), int: (i))
#define ENSURE_float(f) _Generic((f), float: (f))
#define MAX(type, x, y) \
(type)GENERIC_MAX(ENSURE_##type(x), ENSURE_##type(y))
Usage
MAX(int, 2, 3)
Explanation
The macro MAX creates another macro based on the type
parameter. This control macro, if implemented for the given type, is used to check that both parameters are of the correct type. If the type
is not supported, there will be a compiler error.
If either x or y is not of the correct type, there will be a compiler error in the ENSURE_
macros. More such macros can be added if more types are supported. I've assumed that only arithmetic types (integers, floats, pointers etc) will be used and not structs or arrays etc.
If all types are correct, the GENERIC_MAX macro will be called. Extra parenthesis are needed around each macro parameter, as the usual standard precaution when writing C macros.
Then there's the usual problems with implicit type promotions in C. The ?:
operator balances the 2nd and 3rd operand against each other. For example, the result of GENERIC_MAX(my_char1, my_char2)
would be an int
. To prevent the macro from doing such potentially dangerous type promotions, a final type cast to the intended type was used.
Rationale
We want both parameters to the macro to be of the same type. If one of them is of a different type, the macro is no longer type safe, because an operator like ?:
will yield implicit type promotions. And because it does, we also always need to cast the final result back to the intended type as explained above.
A macro with just one parameter could have been written in a much simpler way. But with 2 or more parameters, there is a need to include an extra type parameter. Because something like this is unfortunately impossible:
// this won't work
#define MAX(x, y) \
_Generic((x), \
int: GENERIC_MAX(x, ENSURE_int(y)) \
float: GENERIC_MAX(x, ENSURE_float(y)) \
)
The problem is that if the above macro is called as MAX(1, 2)
with two int
, it will still try to macro-expand all possible scenarios of the _Generic
association list. So the ENSURE_float
macro will get expanded too, even though it isn't relevant for int
. And since that macro intentionally only contains the float
type, the code won't compile.
To solve this, I created the macro name during the pre-processor phase instead, with the ## operator, so that no macro gets accidentally expanded.
Examples
#include <stdio.h>
#define GENERIC_MAX(x, y) ((x) > (y) ? (x) : (y))
#define ENSURE_int(i) _Generic((i), int: (i))
#define ENSURE_float(f) _Generic((f), float: (f))
#define MAX(type, x, y) \
(type)GENERIC_MAX(ENSURE_##type(x), ENSURE_##type(y))
int main (void)
{
int ia = 1, ib = 2;
float fa = 3.0f, fb = 4.0f;
double da = 5.0, db = 6.0;
printf("%d\n", MAX(int, ia, ib)); // ok
printf("%f\n", MAX(float, fa, fb)); // ok
//printf("%d\n", MAX(int, ia, fa)); compiler error, one of the types is wrong
//printf("%f\n", MAX(float, fa, ib)); compiler error, one of the types is wrong
//printf("%f\n", MAX(double, fa, fb)); compiler error, the specified type is wrong
//printf("%f\n", MAX(float, da, db)); compiler error, one of the types is wrong
//printf("%d\n", MAX(unsigned int, ia, ib)); // wont get away with this either
//printf("%d\n", MAX(int32_t, ia, ib)); // wont get away with this either
return 0;
}
Finally I've got the solution for this issue.
This issue occurs only when the app is not at all running. (neither in the background nor in the foreground). When the app runs on either foreground or background the notification icon is displayed properly.(not the white square)
So what we've to set is the same configuration for notification icon in Backend APIs as that of Frontend.
In the frontend we've used React Native and for push notification we've used react-native-fcm npm package.
FCM.on("notification", notif => {
FCM.presentLocalNotification({
body: notif.fcm.body,
title: notif.fcm.title,
big_text: notif.fcm.body,
priority: "high",
large_icon: "notification_icon", // notification icon
icon: "notification_icon",
show_in_foreground: true,
color: '#8bc34b',
vibrate: 300,
lights: true,
status: notif.status
});
});
We've used fcm-push npm package using Node.js as a backend for push notification and set the payload structure as follows.
{
to: '/topics/user', // required
data: {
id:212,
message: 'test message',
title: 'test title'
},
notification: {
title: 'test title',
body: 'test message',
icon : 'notification_icon', // same name as mentioned in the front end
color : '#8bc34b',
click_action : "BROADCAST"
}
}
What it basically searches for the notification_icon image stored locally in our Android system.
bool is a fundamental datatype in C++. Converting true
to an integer type will yield 1, and converting false
will yield 0 (4.5/4 and 4.7/4). In C, until C99, there was no bool datatype, and people did stuff like
enum bool {
false, true
};
So did the Windows API. Starting with C99, we have _Bool
as a basic data type. Including stdbool.h
will typedef #define
that to bool
and provide the constants true
and false
. They didn't make bool a basic data-type (and thus a keyword) because of compatibility issues with existing code.
A generic solution that doesn't limit you to "this image" and "that image" only may be to add the 'onmouseover' and 'onmouseout' tags to the HTML code itself.
HTML
<img src="img1.jpg" onmouseover="swap('img2.jpg')" onmouseout="swap('img1.jpg')" />
JavaScript
function swap(newImg){
this.src = newImg;
}
Depending on your setup, maybe something like this would work better (and requires less HTML modification).
HTML
<img src="img1.jpg" id="ref1" />
<img src="img3.jpg" id="ref2" />
<img src="img5.jpg" id="ref3" />
JavaScript / jQuery
// Declare Arrays
imgList = new Array();
imgList["ref1"] = new Array();
imgList["ref2"] = new Array();
imgList["ref3"] = new Array();
//Set values for each mouse state
imgList["ref1"]["out"] = "img1.jpg";
imgList["ref1"]["over"] = "img2.jpg";
imgList["ref2"]["out"] = "img3.jpg";
imgList["ref2"]["over"] = "img4.jpg";
imgList["ref3"]["out"] = "img5.jpg";
imgList["ref3"]["over"] = "img6.jpg";
//Add the swapping functions
$("img").mouseover(function(){
$(this).attr("src", imgList[ $(this).attr("id") ]["over"]);
}
$("img").mouseout(function(){
$(this).attr("src", imgList[ $(this).attr("id") ]["out"]);
}

In Windows, if you have mapped network drives and you don't know the UNC path for them, you can start a command prompt (Start ? Run ? cmd.exe) and use the net use
command to list your mapped drives and their UNC paths:
C:\>net use
New connections will be remembered.
Status Local Remote Network
-------------------------------------------------------------------------------
OK Q: \\server1\foo Microsoft Windows Network
OK X: \\server2\bar Microsoft Windows Network
The command completed successfully.
Note that this shows the list of mapped and connected network file shares for the user context the command is run under. If you run cmd.exe
under your own user account, the results shown are the network file shares for yourself. If you run cmd.exe
under another user account, such as the local Administrator, you will instead see the network file shares for that user.
I've found that you can use any subset condition for a given column by wrapping it in []. For instance, you have a df with columns ['Product','Time', 'Year', 'Color']
And let's say you want to include products made before 2014. You could write,
df[df['Year'] < 2014]
To return all the rows where this is the case. You can add different conditions.
df[df['Year'] < 2014][df['Color' == 'Red']
Then just choose the columns you want as directed above. For instance, the product color and key for the df above,
df[df['Year'] < 2014][df['Color'] == 'Red'][['Product','Color']]

//in preperation for ES6
String.prototype.lpad || (String.prototype.lpad = function( length, charOptional )
{
if (length <= this.length) return this;
return ( new Array((length||0)+1).join(String(charOptional)||' ') + (this||'') ).slice( -(length||0) );
});
'abc'.lpad(5,'.') == '..abc'
String(5679).lpad(10,0) == '0000005679'
String().lpad(4,'-') == '----' // repeat string
There is a simple solution for you called unique_together which does exactly what you want.
For example:
class MyModel(models.Model):
field1 = models.CharField(max_length=50)
field2 = models.CharField(max_length=50)
class Meta:
unique_together = ('field1', 'field2',)
And in your case:
class Volume(models.Model):
id = models.AutoField(primary_key=True)
journal_id = models.ForeignKey(Journals, db_column='jid', null=True, verbose_name = "Journal")
volume_number = models.CharField('Volume Number', max_length=100)
comments = models.TextField('Comments', max_length=4000, blank=True)
class Meta:
unique_together = ('journal_id', 'volume_number',)
You can access the full uri/url with 'document.referrer'
Check https://developer.mozilla.org/en-US/docs/Web/API/Document/referrer
Try this:
#signin input {
background-color:#FFF;
height: 1.5em;
/* or */
line-height: 1.5em;
}
From the manual, pathinfo:
<?php
$path_parts = pathinfo('/www/htdocs/index.html');
echo $path_parts['dirname'], "\n";
echo $path_parts['basename'], "\n";
echo $path_parts['extension'], "\n";
echo $path_parts['filename'], "\n"; // Since PHP 5.2.0
?>
It doesn't have to be a complete path to operate properly. It will just as happily parse file.jpg
as /path/to/my/file.jpg
.
On client:
axios.get('/api', {
params: {
foo: 'bar'
}
});
On server:
function get(req, res, next) {
let param = req.query.foo
.....
}
If you want to find one element or None
use default in next
, it won't raise StopIteration
if the item was not found in the list:
first_or_default = next((x for x in lst if ...), None)
-m
means the parent number.
From the git doc:
Usually you cannot cherry-pick a merge because you do not know which side of the merge should be considered the mainline. This option specifies the parent number (starting from 1) of the mainline and allows cherry-pick to replay the change relative to the specified parent.
For example, if your commit tree is like below:
- A - D - E - F - master
\ /
B - C branch one
then git cherry-pick E
will produce the issue you faced.
git cherry-pick E -m 1
means using D-E
, while git cherry-pick E -m 2
means using B-C-E
.
SuppressFinalize
should only be called by a class that has a finalizer. It's informing the Garbage Collector (GC) that this
object was cleaned up fully.
The recommended IDisposable
pattern when you have a finalizer is:
public class MyClass : IDisposable
{
private bool disposed = false;
protected virtual void Dispose(bool disposing)
{
if (!disposed)
{
if (disposing)
{
// called via myClass.Dispose().
// OK to use any private object references
}
// Release unmanaged resources.
// Set large fields to null.
disposed = true;
}
}
public void Dispose() // Implement IDisposable
{
Dispose(true);
GC.SuppressFinalize(this);
}
~MyClass() // the finalizer
{
Dispose(false);
}
}
Normally, the CLR keeps tabs on objects with a finalizer when they are created (making them more expensive to create). SuppressFinalize
tells the GC that the object was cleaned up properly and doesn't need to go onto the finalizer queue. It looks like a C++ destructor, but doesn't act anything like one.
The SuppressFinalize
optimization is not trivial, as your objects can live a long time waiting on the finalizer queue. Don't be tempted to call SuppressFinalize
on other objects mind you. That's a serious defect waiting to happen.
Design guidelines inform us that a finalizer isn't necessary if your object implements IDisposable
, but if you have a finalizer you should implement IDisposable
to allow deterministic cleanup of your class.
Most of the time you should be able to get away with IDisposable
to clean up resources. You should only need a finalizer when your object holds onto unmanaged resources and you need to guarantee those resources are cleaned up.
Note: Sometimes coders will add a finalizer to debug builds of their own IDisposable
classes in order to test that code has disposed their IDisposable
object properly.
public void Dispose() // Implement IDisposable
{
Dispose(true);
#if DEBUG
GC.SuppressFinalize(this);
#endif
}
#if DEBUG
~MyClass() // the finalizer
{
Dispose(false);
}
#endif
Python sort function sorts tuples correctly (i.e. using the familiar lexicographical order):
a = [(2, "b"), (1, "a"), (2, "a"), (3, "c")]
print sorted(a)
#[(1, 'a'), (2, 'a'), (2, 'b'), (3, 'c')]
Useful if you want to sort a list of persons after age and then name.
The angular-split
component is not supported in Angular 6, so to make it compatible with Angular 6 install following dependency in your application
To get this working until it's updated use:
"dependencies": {
"angular-split": "1.0.0-rc.3",
"rxjs": "^6.2.2",
"rxjs-compat": "^6.2.2",
}
Do you have something against splitting it up?
...FROM <blah>
WHERE
(fieldA LIKE '%THIS%' OR fieldA LIKE '%THAT%')
AND something = else
80 % of the times, this would due to wrong input by in soapRequest.xml file
mcilist = (from mci in mcilist select mci).Distinct().ToList();
Do it like this :
<div id="footer">
<ul>
<li><a href="/1.html">Link 1</a></li>
<li><a href="/2.html">Link 2</a></li>
<li><a href="/3.html">Link 3</a></li>
<li><a href="/4.html">Link 4</a></li>
<li><a href="/5.html">Link 5</a></li>
</ul>
</div>
And the CSS:
#footer {
background-color:#ccc;
height:39px;
line-height:36px;
margin:0 auto;
text-align:center;
width:950px;
}
#footer ul li {
display:inline;
font-family:Arial,sans-serif;
font-size:1em;
padding:0 2px;
text-decoration:none;
}
You should bind a function to keyup event
textarea.keyup = function(){
textarea.value.length....
}
with jquery
$('textarea').keyup(function(){
var length = $(this).val().length;
});

1 is most readable not compatible with all compilers.
No ISO C compiler has a built in type called bool
. ISO C99 compilers have a type _Bool
, and a header which typedef's bool
. So compatability is simply a case of providing your own header if the compiler is not C99 compliant (VC++ for example).
Of course a simpler approach is to compile your C code as C++.
You can't access an <iframe>
with different origin using JavaScript, it would be a huge security flaw if you could do it. For the same-origin policy browsers block scripts trying to access a frame with a different origin.
Origin is considered different if at least one of the following parts of the address isn't maintained:
protocol://hostname:port/...
Protocol, hostname and port must be the same of your domain if you want to access a frame.
NOTE: Internet Explorer is known to not strictly follow this rule, see here for details.
Here's what would happen trying to access the following URLs from http://www.example.com/home/index.html
URL RESULT
http://www.example.com/home/other.html -> Success
http://www.example.com/dir/inner/another.php -> Success
http://www.example.com:80 -> Success (default port for HTTP)
http://www.example.com:2251 -> Failure: different port
http://data.example.com/dir/other.html -> Failure: different hostname
https://www.example.com/home/index.html:80 -> Failure: different protocol
ftp://www.example.com:21 -> Failure: different protocol & port
https://google.com/search?q=james+bond -> Failure: different protocol, port & hostname
Even though same-origin policy blocks scripts from accessing the content of sites with a different origin, if you own both the pages, you can work around this problem using window.postMessage
and its relative message
event to send messages between the two pages, like this:
In your main page:
const frame = document.getElementById('your-frame-id');
frame.contentWindow.postMessage(/*any variable or object here*/, 'http://your-second-site.com');
The second argument to postMessage()
can be '*'
to indicate no preference about the origin of the destination. A target origin should always be provided when possible, to avoid disclosing the data you send to any other site.
In your <iframe>
(contained in the main page):
window.addEventListener('message', event => {
// IMPORTANT: check the origin of the data!
if (event.origin.startsWith('http://your-first-site.com')) {
// The data was sent from your site.
// Data sent with postMessage is stored in event.data:
console.log(event.data);
} else {
// The data was NOT sent from your site!
// Be careful! Do not use it. This else branch is
// here just for clarity, you usually shouldn't need it.
return;
}
});
This method can be applied in both directions, creating a listener in the main page too, and receiving responses from the frame. The same logic can also be implemented in pop-ups and basically any new window generated by the main page (e.g. using window.open()
) as well, without any difference.
There already are some good answers about this topic (I just found them googling), so, for the browsers where this is possible, I'll link the relative answer. However, please remember that disabling the same-origin policy will only affect your browser. Also, running a browser with same-origin security settings disabled grants any website access to cross-origin resources, so it's very unsafe and should NEVER be done if you do not know exactly what you are doing (e.g. development purposes).
Make the member private and add a setter/getter pair. In your setter, if null, then set default value instead. Additionally, I have shown the snippet with the getter also returning a default when internal value is null.
class JavaObject {
private static final String DEFAULT="Default Value";
public JavaObject() {
}
@NotNull
private String notNullMember;
public void setNotNullMember(String value){
if (value==null) { notNullMember=DEFAULT; return; }
notNullMember=value;
return;
}
public String getNotNullMember(){
if (notNullMember==null) { return DEFAULT;}
return notNullMember;
}
public String optionalMember;
}
When you have multiple files, an idea is to show only the first file and the number of the hidden file names.
$('.custom-file input').change(function() {
var $el = $(this),
files = $el[0].files,
label = files[0].name;
if (files.length > 1) {
label = label + " and " + String(files.length - 1) + " more files"
}
$el.next('.custom-file-label').html(label);
});
This would work fine.
Push-Location $PSScriptRoot
Write-Host CurrentDirectory $CurDir
Declare object of EditText on top of class:
EditText myEditText;
Find EditText in onCreate Function and setOnFocusChangeListener of EditText:
myEditText = findViewById(R.id.yourEditTextNameInxml);
myEditText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View view, boolean hasFocus) {
if (!hasFocus) {
Toast.makeText(this, "Focus Lose", Toast.LENGTH_SHORT).show();
}else{
Toast.makeText(this, "Get Focus", Toast.LENGTH_SHORT).show();
}
}
});
It works fine.
It is possible to use patterns in a .gitignore
file. See the gitignore man page. The pattern */target/*
should ignore any directory named target and anything under it. Or you may try */target/**
to ignore everything under target.
This solution did the trick for me
<a ng-style="{true: {paddingLeft: '25px'}, false: {}}[deleteTriggered]">...</a>
This is a late contribution, but there is a valid case for casting json_decode
with (array)
.
Consider the following:
$jsondata = '';
$arr = json_decode($jsondata, true);
foreach ($arr as $k=>$v){
echo $v; // etc.
}
If $jsondata
is ever returned as an empty string (as in my experience it often is), json_decode
will return NULL
, resulting in the error Warning: Invalid argument supplied for foreach() on line 3. You could add a line of if/then code or a ternary operator, but IMO it's cleaner to simply change line 2 to ...
$arr = (array) json_decode($jsondata,true);
... unless you are json_decode
ing millions of large arrays at once, in which case as @TCB13 points out, performance could be negatively effected.
How about this
var parsed = new Function('return ' + stringifiedJSON )();
This is a safer alternative for eval
.
var stringifiedJSON = '{"hello":"world"}';_x000D_
var parsed = new Function('return ' + stringifiedJSON)();_x000D_
alert(parsed.hello);

A bit late, but to anyone who is wondering why they are getting the "Warning: Cannot use a scalar value as an array" message;
the reason is because somewhere you have first declared your variable with a normal integer or string and then later you are trying to turn it into an array.
hope that helps
Funny, I was just researching this yesterday!
I personally use Monaco 10 or 11 for the Mac, but a good cross platform font would have to be Droid Sans Mono: http://damieng.com/blog/2007/11/14/droid-sans-mono-great-coding-font Or DejaVu sans mono is another great one (goes under a lot of different names, will be Menlo on SNow leopard and is really just a repackaged Prima/Vera) check it out here: Prima/Vera...

There is no built in function with this capability. The close would be to save the file in a folder named for the current date and use the =INFO("directory") function.
My personal experience was that I had installed the Team Foundation Server client for 2017 first (was using it as a Proof of Concept for our QA team, while I was still using VS2015), then followed it up with Installing Visual Studio 2017 later to begin development.
What I ended up with on my Start Menu was a Visual Studio 2017 and a Visual Studio 2017 (2). The Visual Studio 2017 (2) had all the templates I was missing. Following the steps found in the First answer to this question (which were clear and easy to follow) did not fix my issue. I had thought that launching the client would upgrade to the Development Client, but it did not. I renamed it to Visual Studio Professional, and now have everything I need. Not sure if this happens to anyone else, but it was what happened to me, so I hope this helps someone.
A java program to set AWS environment vairiable.
Map<String, String> environment = new HashMap<String, String>();
environment.put("AWS_ACCESS_KEY_ID", "*****************");
environment.put("AWS_SECRET_KEY", "*************************");
private static void setEnv(Map<String, String> newenv) throws Exception {

I just resolved this problem with a little hack:
static int s_CellHeight = 30;
static int s_CellHeightEditing = 60;
- (void)onTimer {
cellHeight++;
[tableView reloadData];
if (cellHeight < s_CellHeightEditing)
heightAnimationTimer = [[NSTimer scheduledTimerWithTimeInterval:0.001 target:self selector:@selector(onTimer) userInfo:nil repeats:NO] retain];
}
- (CGFloat)tableView:(UITableView *)_tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (isInEdit) {
return cellHeight;
}
cellHeight = s_CellHeight;
return s_CellHeight;
}
When I need to expand the cell height I set isInEdit = YES
and call the method [self onTimer]
and it animates the cell growth until it reach the s_CellHeightEditing value :-)
you can do like this:
if("merchant_id" in thisSession){ /** will return true if exist */
console.log('Exist!');
}
or
if(thisSession["merchant_id"]){ /** will return its value if exist */
console.log('Exist!');
}
You could also use strdup
:
The strdup() function returns a pointer to a new string which is a duplicate of the string s.
Memory for the new string is obtained with malloc(3), and can be freed with free(3).
For you example:
char *a = strdup("stack overflow");
For my case, the issue was with using Lombok's experimental feature @UtilityClass in my java project in Intellij Idea, to annotate a class methods as "static". When I explicitly made each method of the class as "static" instead of using the annotation, all the compilation issues disappeared.
I thinks it is vary helpful way.

Try to download binary zip (for ex. Maven 3.0.5 (Binary zip)) instead of complete source in official maven site. Also make sure that command line recognizes java and javac commands. I noticed that Maven Source zip didn't include any libraries at lib folder however Binary zip had them + in boot folder it had plexus-classworlds-2.4.jar. Perhaps the problem was with the absence of these libraries. Anyway it helped me so my M2_HOME is: C:\Program Files\Java\apache-maven-3.0.5 and at PATH I put: C:\Program Files\Java\apache-maven-3.0.5\bin.
It exits the function and returns nothing.
Something like return 1;
would be incorrect since it returns integer 1.

The problem here seems to be that you're reassigning $today
by assigning a string to it:
$today = $dd+'/'+$mm+'/'+$yyyy;
Strings don't have getDate
.
Also, $today.getDate()-1
just gives you the day of the month minus one; it doesn't give you the full date of 'yesterday'. Try this:
$today = new Date();
$yesterday = new Date($today);
$yesterday.setDate($today.getDate() - 1); //setDate also supports negative values, which cause the month to rollover.
Then just apply the formatting code you wrote:
var $dd = $yesterday.getDate();
var $mm = $yesterday.getMonth()+1; //January is 0!
var $yyyy = $yesterday.getFullYear();
if($dd<10){$dd='0'+$dd} if($mm<10){$mm='0'+$mm} $yesterday = $dd+'/'+$mm+'/'+$yyyy;
Because of the last statement, $yesterday
is now a String
(not a Date
) containing the formatted date.
No way what is suggested here works - the error "bitmap xxx not defined" is ever present. And yes, I set the correct path to it.
What it did work is this:
imgicon = PhotoImage(file=os.path.join(sp,'myicon.gif'))
root.tk.call('wm', 'iconphoto', root._w, imgicon)
where sp
is the script path, and root
the Tk root window.
It's hard to understand how it does work (I shamelessly copied it from fedoraforums) but it works
Your html should be like this:
<button onclick="doSomething" id="id_button">action</button>
And renaming your input-paramter to event like this
function doSomething(event){
var source = event.target || event.srcElement;
console.log(source);
}
would solve your problem.
As a side note, I'd suggest taking a look at jQuery and unobtrusive javascript

Here is jsFiddle with example you can edit
If you don't wish to use 3rd party classes then the following is how you set the post body...
NSURL *aUrl = [NSURL URLWithString:@"http://www.apple.com/"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:aUrl
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:60.0];
[request setHTTPMethod:@"POST"];
NSString *postString = @"company=Locassa&quality=AWESOME!";
[request setHTTPBody:[postString dataUsingEncoding:NSUTF8StringEncoding]];
NSURLConnection *connection= [[NSURLConnection alloc] initWithRequest:request
delegate:self];
Simply append your key/value pair to the post string
Undefined offset means there's an empty array key for example:
$a = array('Felix','Jon','Java');
// This will result in an "Undefined offset" because the size of the array
// is three (3), thus, 0,1,2 without 3
echo $a[3];
You can solve the problem using a loop (while):
$i = 0;
while ($row = mysqli_fetch_assoc($result)) {
// Increase count by 1, thus, $i=1
$i++;
$groupname[$i] = base64_decode(base64_decode($row['groupname']));
// Set the first position of the array to null or empty
$groupname[0] = "";
}
My 5 cents:
async/await
if and only if you do an IO operation, like DB or external service webservice.P.S. There are exceptional cases for point 1, but you need to have a good understanding of async internals for this.
As an additional advantage, you can do few IO calls in parallel if needed:
Task task1 = FooAsync(); // launch it, but don't wait for result
Task task2 = BarAsync(); // launch bar; now both foo and bar are running
await Task.WhenAll(task1, task2); // this is better in regard to exception handling
// use task1.Result, task2.Result
Since PostgreSQL 9.1 there is the convenient FOREACH
:
DO
$do$
DECLARE
m varchar[];
arr varchar[] := array[['key1','val1'],['key2','val2']];
BEGIN
FOREACH m SLICE 1 IN ARRAY arr
LOOP
RAISE NOTICE 'another_func(%,%)',m[1], m[2];
END LOOP;
END
$do$
Solution for older versions:
DO
$do$
DECLARE
arr varchar[] := '{{key1,val1},{key2,val2}}';
BEGIN
FOR i IN array_lower(arr, 1) .. array_upper(arr, 1)
LOOP
RAISE NOTICE 'another_func(%,%)',arr[i][1], arr[i][2];
END LOOP;
END
$do$
Also, there is no difference between varchar[]
and varchar[][]
for the PostgreSQL type system. I explain in more detail here.
The DO
statement requires at least PostgreSQL 9.0, and LANGUAGE plpgsql
is the default (so you can omit the declaration).
List<String> list = new ArrayList<>();
list.add("Hello");
list.add("Hello");
list.add("World");
Map<String, List<String>> collect = list.stream()
.collect(Collectors.groupingBy(o -> o));
collect.entrySet()
.forEach(e -> System.out.println(e.getKey() + " - " + e.getValue().size()));
In preparation before working offline just run

You could always use a subquery so you can use the alias; Of course, check the performance (Possible the db server will run both the same, but never hurts to verify):
SELECT ItemName, FirstLetter, COUNT(ItemName)
FROM (
SELECT ItemName, SUBSTRING(ItemName, 1, 1) AS FirstLetter
FROM table1
) ItemNames
GROUP BY ItemName, FirstLetter
Install firebug: http://getfirebug.com/logging . You can use its console to test Javascript code. Google Chrome comes with Web Inspector in which you can do the same. IE and Safari also have Web Developer tools in which you can test Javascript.
If nothing else works, open debug perspective, clear all existing breakpoints and then set them back again.
Another easy way is to use 2 premade sizes and pass them as parameter when calling the function in your html. use: 'lg' for large modals with width 900px 'sm' for small modals with width 300px or passing no parameter you use the default size which is 600px.
example code:
$scope.openModal = function (size) {
var modal = $modal.open({
templateUrl: "/partials/welcome",
controller: "welcomeCtrl",
backdrop: "static",
scope: $scope,
size: size,
});
modal.result.then(
//close
function (result) {
var a = result;
},
//dismiss
function (result) {
var a = result;
});
};
and in the html I would use something like the following:
<button ng-click="openModal('lg')">open Modal</button>
As other answers pointed out, it is most likely generated by some tool.
But if I were the original author of the file, my answer would be: Consistency.
If I am not allowed to put double quotes in my attributes, why put them in the element's content ? Why do these specs always have these exceptional cases ..
If I had to write the HTML spec, I would say All double quotes need to be encoded
. Done.
Today it is like In attribute values we need to encode double quotes, except when the attribute value itself is defined by single quotes. In the content of elements, double quotes can be, but are not required to be, encoded.
(And I am surely forgetting some cases here).
Double quotes are a keyword of the spec, encode them. Lesser/greater than are a keyword of the spec, encode them. etc..
I don't think that given answers are responding to the question, I think this following should answer to the first part :
const arr = [
{ Phase: "Phase 1", Step: "Step 1", Task: "Task 1", Value: "5" },
{ Phase: "Phase 1", Step: "Step 1", Task: "Task 2", Value: "10" },
{ Phase: "Phase 1", Step: "Step 2", Task: "Task 1", Value: "15" },
{ Phase: "Phase 1", Step: "Step 2", Task: "Task 2", Value: "20" },
{ Phase: "Phase 2", Step: "Step 1", Task: "Task 1", Value: "25" },
{ Phase: "Phase 2", Step: "Step 1", Task: "Task 2", Value: "30" },
{ Phase: "Phase 2", Step: "Step 2", Task: "Task 1", Value: "35" },
{ Phase: "Phase 2", Step: "Step 2", Task: "Task 2", Value: "40" }
]
const groupBy = (key) => arr.reduce((total, currentValue) => {
const newTotal = total;
if (
total.length &&
total[total.length - 1][key] === currentValue[key]
)
newTotal[total.length - 1] = {
...total[total.length - 1],
...currentValue,
Value: parseInt(total[total.length - 1].Value) + parseInt(currentValue.Value),
};
else newTotal[total.length] = currentValue;
return newTotal;
}, []);
console.log(groupBy('Phase'));
// => [{ Phase: "Phase 1", Value: 50 },{ Phase: "Phase 2", Value: 130 }]

No file will be create when you make a File object, it is only an interface.
To make working with files easier, there is an existing .toFile
function on Uri
You can also add an extension property on File and/or Uri, to simplify usage further.
val File?.exists get() = this?.exists() ?: false
val Uri?.exists get() = File(this.toString).exists()
Then just use uri.exists
or file.exists
to check.
You should initialize your variables outside the while loop. Outside the while loop, they currently have no scope. You are just relying on the good graces of php to let the values carry over outside the loop
$hn = "";
$pid = "";
$datereg = "";
$prefix = "";
$fname = "";
$lname = "";
$age = "";
$sex = "";
while (...){}
alternatively, it looks like you are just expecting a single row back. so you could just say
$row = pg_fetch_array($result);
if(!row) {
return array();
}
$hn = $row["patient_hn"];
$pid = $row["patient_id"];
$datereg = $row["patient_date_register"];
$prefix = $row["patient_prefix"];
$fname = $row["patient_fname"];
$lname = $row["patient_lname"];
$age = $row["patient_age"];
$sex = $row["patient_sex"];
return array($hn,$pid,$datereg,$prefix,$fname,$lname,$age,$sex) ;
Why not this:
CREATE PROCEDURE SP_Reporting(IN tablename VARCHAR(20))
BEGIN
IF tablename IS NOT NULL THEN
#proceed the code
END IF;
# Do nothing otherwise
END;
Late to the game but here a handy little category I use that accounts for decimal places and the local symbol used for it. link to its gist here
@interface NSString (Extension)
- (BOOL) isAnEmail;
- (BOOL) isNumeric;
@end
@implementation NSString (Extension)
/**
* Determines if the current string is a valid email address.
*
* @return BOOL - True if the string is a valid email address.
*/
- (BOOL) isAnEmail
{
NSString *emailRegex = @"[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,4}";
NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
return [emailTest evaluateWithObject:self];
}
/**
* Determines if the current NSString is numeric or not. It also accounts for the localised (Germany for example use "," instead of ".") decimal point and includes these as a valid number.

The documentation for Platform
width()
and height()
, it's stated that these methods use window.innerWidth
and window.innerHeight
respectively. But using the methods are preferred since the dimensions are cached values, which reduces the chance of multiple and expensive DOM reads.
import { Platform } from 'ionic-angular';
...
private width:number;
private height:number;
constructor(private platform: Platform){
platform.ready().then(() => {
this.width = platform.width();
this.height = platform.height();
});
}
Try using this:
If you specify
ON DUPLICATE KEY UPDATE
, and a row is inserted that would cause a duplicate value in aUNIQUE index or
PRIMARY KEY, MySQL performs an [
UPDATE`](http://dev.mysql.com/doc/refman/5.7/en/update.html) of the old row...The
ON DUPLICATE KEY UPDATE
clause can contain multiple column assignments, separated by commas.With
ON DUPLICATE KEY UPDATE
, the affected-rows value per row is 1 if the row is inserted as a new row, 2 if an existing row is updated, and 0 if an existing row is set to its current values. If you specify theCLIENT_FOUND_ROWS
flag tomysql_real_connect()
when connecting to mysqld, the affected-rows value is 1 (not 0) if an existing row is set to its current values...
Starting with Go 1.16, you can use the os.ReadDir function.
func ReadDir(name string) ([]DirEntry, error)
It reads a given directory and returns a DirEntry
slice that contains the directory entries sorted by filename.
It's an optimistic function, so that, when an error occurs while reading the directory entries, it tries to return you a slice with the filenames up to the point before the error.
package main
import (
"fmt"
"log"
"os"
)
func main() {
files, err := os.ReadDir(".")
if err != nil {
log.Fatal(err)
}
for _, file := range files {
fmt.Println(file.Name())
}
}
Go 1.16 (Q1 2021) will propose, with CL 243908 and CL 243914 , the ReadDir
function, based on the FS
interface:
// An FS provides access to a hierarchical file system.
//
// The FS interface is the minimum implementation required of the file system.
// A file system may implement additional interfaces,
// such as fsutil.ReadFileFS, to provide additional or optimized functionality.
// See io/fsutil for details.
type FS interface {
// Open opens the named file.
//
// When Open returns an error, it should be of type *PathError
// with the Op field set to "open", the Path field set to name,
// and the Err field describing the problem.
//
// Open should reject attempts to open names that do not satisfy
// ValidPath(name), returning a *PathError with Err set to
// ErrInvalid or ErrNotExist.
Open(name string) (File, error)
}
That allows for "os: add ReadDir
method for lightweight directory reading":
See commit a4ede9f:
// ReadDir reads the contents of the directory associated with the file f
// and returns a slice of DirEntry values in directory order.
// Subsequent calls on the same file will yield later DirEntry records in the directory.
//
// If n > 0, ReadDir returns at most n DirEntry records.
// In this case, if ReadDir returns an empty slice, it will return an error explaining why.
// At the end of a directory, the error is io.EOF.
//
// If n <= 0, ReadDir returns all the DirEntry records remaining in the directory.
// When it succeeds, it returns a nil error (not io.EOF).
func (f *File) ReadDir(n int) ([]DirEntry, error)
// A DirEntry is an entry read from a directory (using the ReadDir method).
type DirEntry interface {
// Name returns the name of the file (or subdirectory) described by the entry.
// This name is only the final element of the path, not the entire path.
// For example, Name would return "hello.go" not "/home/gopher/hello.go".
Name() string
// IsDir reports whether the entry describes a subdirectory.
IsDir() bool
// Type returns the type bits for the entry.
// The type bits are a subset of the usual FileMode bits, those returned by the FileMode.Type method.
Type() os.FileMode
// Info returns the FileInfo for the file or subdirectory described by the entry.
// The returned FileInfo may be from the time of the original directory read
// or from the time of the call to Info. If the file has been removed or renamed
// since the directory read, Info may return an error satisfying errors.Is(err, ErrNotExist).
// If the entry denotes a symbolic link, Info reports the information about the link itself,
// not the link's target.
Info() (FileInfo, error)
}
src/os/os_test.go#testReadDir()
illustrates its usage:
file, err := Open(dir)
if err != nil {
t.Fatalf("open %q failed: %v", dir, err)
}
defer file.Close()
s, err2 := file.ReadDir(-1)
if err2 != nil {
t.Fatalf("ReadDir %q failed: %v", dir, err2)
}
Ben Hoyt points out in the comments to Go 1.16 os.ReadDir
:
os.ReadDir(path string) ([]os.DirEntry, error)
, which you'll be able to call directly without theOpen
dance.
So you can probably shorten this to justos.ReadDir
, as that's the concrete function most people will call.
See commit 3d913a9 (Dec. 2020):
os
: addReadFile
,WriteFile
,CreateTemp
(wasTempFile
),MkdirTemp
(wasTempDir
) fromio/ioutil
io/ioutil
was a poorly defined collection of helpers.Proposal #40025 moved out the generic I/O helpers to io. This CL for proposal #42026 moves the OS-specific helpers to
os
, making the entireio/ioutil
package deprecated.
os.ReadDir
returns[]DirEntry
, in contrast toioutil.ReadDir
's[]FileInfo
.
(Providing a helper that returns[]DirEntry
is one of the primary motivations for this change.)
Short answer: AngularJS ("jqlite") doesn't support this. Include jQuery on your page (before including Angular), and it should work. See https://groups.google.com/d/topic/angular/H4haaMePJU0/discussion
Here's my really quick-n-dirty one:
<!-- HTML file -->
<html ng-app="num">
<head></head>
<body ng-controller="numCtrl">
<form class="digits" name="digits" ng-submit="getGrades()" novalidate >
<input type="text" placeholder="digits here plz" name="nums" ng-model="nums" required ng-pattern="/^(\d)+$/" />
<p class="alert" ng-show="digits.nums.$error.pattern">Numbers only, please.</p>
<br>
<input type="text" placeholder="txt here plz" name="alpha" ng-model="alpha" required ng-pattern="/^(\D)+$/" />
<p class="alert" ng-show="digits.alpha.$error.pattern">Text only, please.</p>
<br>
<input class="btn" type="submit" value="Do it!" ng-disabled="!digits.$valid" />
</form>
</body>
</html>
// Javascript file
var app = angular.module('num', ['ngResource']);
app.controller('numCtrl', function($scope, $http){
$scope.digits = {};
});
This requires you include the angular-resource library for persistent bindings to the fields for validation purposes.
Works like a champ in 1.2.0-rc.3+. Modify the regex and you should be all set. Perhaps something like /^(\d|\.)+$/
? As always, validate server-side when you're done.
According to Windows Dev Center:
TextBlock.IsTextSelectionEnabled property
[ Updated for UWP apps on Windows 10. For Windows 8.x articles, see the archive ]
Gets or sets a value that indicates whether text selection is enabled in the TextBlock, either through user action or calling selection-related API.
Thank you Felix Kling, but his answer need a little change:
var MySelect = React.createClass({
getInitialState: function() {
return {
value: 'select'
}
},
change: function(event){
this.setState({value: event.target.value});
},
render: function(){
return(
<div>
<select id="lang" onChange={this.change.bind(this)} value={this.state.value}>
<option value="select">Select</option>
<option value="Java">Java</option>
<option value="C++">C++</option>
</select>
<p></p>
<p>{this.state.value}</p>
</div>
);
}
});
React.render(<MySelect />, document.body);
One thing to be wary of is how to exit from the Generic .ForEach method - see this discussion. Although the link seems to say that this way is the fastest. Not sure why - you'd think they would be equivalent once compiled...
FWIW., the latest version of brew is at protobuf 3.0, and doesn't include any formulae for the older versions. This is somewhat "inconvenient".
While protobuf may be compatible at the wire level, it is absolutely not compatible at the level of generated java classes: you can't use .class files generated with protoc 2.4 with the protobuf-2.5 JAR, etc. etc. This is why updating protobuf versions is such a sensitive topic in the Hadoop stack: it invariably requires coordination across different projects, and is traumatic enough that nobody likes to do it.
perhaps, you can first determine if the DOM does really exists,
function walkmydog() {
//when the user starts entering
var dom = document.getElementById('WallSearch');
if(dom == null){
alert('sorry, WallSearch DOM cannot be found');
return false;
}
if(dom.value.length == 0){
alert("nothing");
}
}
if (document.addEventListener){
document.addEventListener("DOMContentLoaded", walkmydog, false);
}
using System.Windows.Forms;
public class message
{
static void Main()
{
MessageBox.Show("Hello World!");
}
}
You can also do it on the worksheet level captured in the worksheet's change event. If that suites your needs better. Allows for dynamic locking based on values, criteria, ect...
Private Sub Worksheet_Change(ByVal Target As Range)
'set your criteria here
If Target.Column = 1 Then
'must disable events if you change the sheet as it will
'continually trigger the change event
Application.EnableEvents = False
Application.Undo
Application.EnableEvents = True
MsgBox "You cannot do that!"
End If
End Sub

I also had this problem on Ubuntu 16.04.
Fixed by running sudo apt-get install graphviz
in addition to the pip install I had already performed.
First off, this has nothing to do with php. This is a unix permission issue. You need to login as a superuser ( sudo/su ) and type your password, then try that command.
$ su
(type password )
\# your command
$ sudo command
$ (type password)
It might also help if you actually specified the operating system you use.
Bower uses semver syntax, but here are a few quick examples:
You can install a specific version:
$ bower install jquery#1.11.1
You can use ~ to specify 'any version that starts with this':
$ bower install jquery#~1.11
You can specify multiple version requirements together:
$ bower install "jquery#<2.0 >1.10"
On top of the setting :set clipboard=unnamed
, you should use mvim -v
which you can get with brew install macvim
if you're using vim on Terminal.app on Mac OS X 10.9. Default vim does not support clipboard option.
Give 0777 to all files and directories starting from the current path :
chmod -R 0777 ./
The dot operator .
does not need to be escaped inside of a character class []
.
This is an expansion of @Dathan's answer, using html2canvas and FileSaver.js.
$(function() {
$("#btnSave").click(function() {
html2canvas($("#widget"), {
onrendered: function(canvas) {
theCanvas = canvas;
canvas.toBlob(function(blob) {
saveAs(blob, "Dashboard.png");
});
}
});
});
});
This code block waits for the button with the id btnSave
to be clicked. When it is, it converts the widget
div to a canvas element and then uses the saveAs() FileSaver interface (via FileSaver.js in browsers that don't support it natively) to save the div as an image named "Dashboard.png".
An example of this working is available at this fiddle.
You can use standard directory functions
$dir = opendir('/tmp');
while ($file = readdir($dir)) {
if ($file == '.' || $file == '..') {
continue;
}
echo $file;
}
closedir($dir);
Does not seem so. Quote from ECMAScript 6 modules: the final syntax:
You may be wondering – why do we need named exports if we could simply default-export objects (like CommonJS)? The answer is that you can’t enforce a static structure via objects and lose all of the associated advantages (described in the next section).
I suggest to use autotools
:
//##
Place generated object files (.o) into the same directory as their source files, in order to avoid collisions when non-recursive make is used.
AUTOMAKE_OPTIONS = subdir-objects
just including it in Makefile.am
with the other quite simple stuff.
Here is the tutorial.
The centos dockerfile has a default command bash
.
That means, when run in background (-d
), the shell exits immediately.
Update 2017
More recent versions of docker authorize to run a container both in detached mode and in foreground mode (-t
, -i
or -it
)
In that case, you don't need any additional command and this is enough:
docker run -t -d centos
The bash will wait in the background.
That was initially reported in kalyani-chaudhari's answer and detailed in jersey bean's answer.
vonc@voncvb:~$ d ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
4a50fd9e9189 centos "/bin/bash" 8 seconds ago Up 2 seconds wonderful_wright
Note that for alpine, Marinos An reports in the comments:
docker run -t -d alpine/git
does not keep the process up.
Had to do:docker run --entrypoint "/bin/sh" -it alpine/git
Original answer (2015)
As mentioned in this article:
Instead of running with
docker run -i -t image your-command
, using-d
is recommended because you can run your container with just one command and you don’t need to detach terminal of container by hitting Ctrl + P + Q.
However, there is a problem with
-d
option. Your container immediately stops unless the commands keep running in foreground.
Docker requires your command to keep running in the foreground. Otherwise, it thinks that your applications stops and shutdown the container.
The problem is that some application does not run in the foreground. How can we make it easier?
In this situation, you can add
tail -f /dev/null
to your command.
By doing this, even if your main command runs in the background, your container doesn’t stop because tail is keep running in the foreground.
So this would work:
docker run -d centos tail -f /dev/null
A docker ps
would show the centos container still running.
From there, you can attach to it or detach from it (or docker exec
some commands).
@xtrem's answer is good, but I think the toFixed
and the makePercentage
are common use. Define two functions, and we can use that at everywhere.
const R = require('ramda')
const RA = require('ramda-adjunct')
const fix = R.invoker(1, 'toFixed')(2)
const makePercentage = R.when(
RA.isNotNil,
R.compose(R.flip(R.concat)('%'), fix, R.multiply(100)),
)
let a = 0.9988
let b = null
makePercentage(b) // -> null
makePercentage(a) // -> ?????99.88%?????
Your program has to run with Administrative Rights. You can't do this automatically with code, but you can request the user (in code) to elevate the rights of your program while it's running. There's a wiki on how to do this. Alternatively, any program can be run as administrator by right-clicking its icon and clicking "Run as administrator".
However, I wouldn't suggest doing this. It would be better to use something like this:
Environment.GetFolderPath(SpecialFolder.ApplicationData);
to get the AppData Folder path and create a folder there for your app. Then put the temp files there.
public static byte[][] arrayCopy(byte[][] arr){
if(arr!=null){
int[][] arrCopy = new int[arr.length][] ;
System.arraycopy(arr, 0, arrCopy, 0, arr.length);
return arrCopy;
}else { return new int[][]{};}
}
size_t should be defined in your standard library's headers. In my experience, it usually is simply a typedef to unsigned int. The point, though, is that it doesn't have to be. Types like size_t allow the standard library vendor the freedom to change its underlying data types if appropriate for the platform. If you assume size_t is always unsigned int (via casting, etc), you could run into problems in the future if your vendor changes size_t to be e.g. a 64-bit type. It is dangerous to assume anything about this or any other library type for this reason.
You are replacing the starting tag and then putting that back in innerHTML
, so the code will be invalid. Make all the replacements before you put the code back in the element:
var html = strMessage1.innerHTML;
html = html.replace( /aaaaaa./g,'<a href=\"http://www.google.com/');
html = html.replace( /.bbbbbb/g,'/world\">Helloworld</a>');
strMessage1.innerHTML = html;
You can use a deferred object to make a fluid design that works well in webkit browsers. Webkit browsers will fire resize event for each pixel the window is resized, unlike FF and IE which fire the event only once for each resize. As a result, you have no control over the order in which the functions bound to your window resize event will execute. Something like this solves the problem:
var resizeQueue = new $.Deferred(); //new is optional but it sure is descriptive
resizeQueue.resolve();
function resizeAlgorithm() {
//some resize code here
}
$(window).resize(function() {
resizeQueue.done(resizeAlgorithm);
});
This will serialize the execution of your code so that it executes as you intended it to. Beware of pitfalls when passing object methods as callbacks to a deferred. Once such method is executed as a callback to deferred, the 'this' reference will be overwritten with reference to the deferred object and will no longer refer to the object the method belongs to.
In my case I was trying to delete entries that were saved in .git/packed-refs
. You can edit this plain text file and delete entries from it that git br -D
doesn't know how to touch (At least in ver 1.7.9.5).
I found this solution here: https://stackoverflow.com/a/11050880/1695680
You can refine your search to only find those divs with a given class using BS3:
mydivs = soup.find_all("div", {"class": "stylelistrow"})
I liked the accepted answer, but thought it would be neat to enable it to take arrays as well, so I expanded it to this:
Object.prototype.isin = function() {
for(var i = arguments.length; i--;) {
var a = arguments[i];
if(a.constructor === Array) {
for(var j = a.length; j--;)
if(a[j] == this) return true;
}
else if(a == this) return true;
}
return false;
}
var lucky = 7,
more = [7, 11, 42];
lucky.isin(2, 3, 5, 8, more) //true
You can remove type coercion by changing ==
to ===
.
This is sort of an indirect approach, but you could see if a website loads on your web browser of choice from whatever is running on port 80. Or you could telnet to port 80 and see if you get a response that gives you a clue as to what is running on that port and you can go shut it down. Since port 80 is the default port for http traffic chances are there is some sort of http server running there by default, but there's no guarantee.
Here is how I would do it, its an idea not bulletproof design, you need to modify it
In Mark's solution, you will return array([0]=> int 0)
if you try to parse a string such as "test".
$integerIDs = array_map( 'intval', array_filter( explode(',', $string), 'is_numeric' ) );
I once wrote an unround tool, to find the minimal perturbation to a set of numbers to match a goal. It was a different problem, but one could in theory use a similar idea here. In this case, we have a set of choices.
Thus for the first element, we can either round it up to 14, or down to 13. The cost (in a binary integer programming sense) of doing so is less for the round up than the round down, because the round down requires we move that value a larger distance. Similarly, we can round each number up or down, so there are a total of 16 choices we must choose from.
13.626332
47.989636
9.596008
+ 28.788024
-----------
100.000000
I'd normally solve the general problem in MATLAB, here using bintprog, a binary integer programming tool, but there are only a few choices to be tested, so it is easy enough with simple loops to test out each of the 16 alternatives. For example, suppose we were to round this set as:
Original Rounded Absolute error
13.626 13 0.62633
47.99 48 0.01036
9.596 10 0.40399
+ 28.788 29 0.21198
---------------------------------------
100.000 100 1.25266
The total absolute error made is 1.25266. It can be reduced slightly by the following alternative rounding:
Original Rounded Absolute error
13.626 14 0.37367
47.99 48 0.01036
9.596 9 0.59601
+ 28.788 29 0.21198
---------------------------------------
100.000 100 1.19202
In fact, this will be the optimal solution in terms of the absolute error. Of course, if there were 20 terms, the search space will be of size 2^20 = 1048576. For 30 or 40 terms, that space will be of significant size. In that case, you would need to use a tool that can efficiently search the space, perhaps using a branch and bound scheme.
Try what @iFreilicht suggested above. If that didn't work after you've installed webpack and all, you may have just copied a webpack configuration from somewhere online and configured there that you want the output to support CommonJS by mistake. Make sure this isn't the case in webpack.config.js

To expand a little more, there are two kinds of constructors: instance initializers (.ctor), type initializers (.cctor). Build the code below, and explore the IL code in ildasm.exe. You will notice that the static field 'b' will be initialized through .cctor() whereas the instance field will be initialized through .ctor()

You can use the NotMapped
attribute data annotation to instruct Code-First to exclude a particular property
public class Customer
{
public int CustomerID { set; get; }
public string FirstName { set; get; }
public string LastName{ set; get; }
[NotMapped]
public int Age { set; get; }
}
[NotMapped]
attribute is included in the System.ComponentModel.DataAnnotations
namespace.
You can alternatively do this with Fluent API
overriding OnModelCreating
function in your DBContext
class:
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Entity<Customer>().Ignore(t => t.LastName);
base.OnModelCreating(modelBuilder);
}
http://msdn.microsoft.com/en-us/library/hh295847(v=vs.103).aspx
The version I checked is EF 4.3
, which is the latest stable version available when you use NuGet.
Edit : SEP 2017
Data annotation
If you are using asp.net core (2.0 at the time of this writing), The [NotMapped]
attribute can be used on the property level.
public class Customer
{
public int Id { set; get; }
public string FirstName { set; get; }
public string LastName { set; get; }
[NotMapped]
public int FullName { set; get; }
}
Fluent API
public class SchoolContext : DbContext
{
public SchoolContext(DbContextOptions<SchoolContext> options) : base(options)
{
}
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
modelBuilder.Entity<Customer>().Ignore(t => t.FullName);
base.OnModelCreating(modelBuilder);
}
public DbSet<Customer> Customers { get; set; }
}
If you already have the int typed as an Integer you can do this:
Integer y = 1;
long x = y.longValue();
If the open fails, an error of level E_WARNING is generated. You may use @ to suppress this warning.
a.h:
#ifndef A_H
#define A_H
struct a {
int i;
struct b {
int j;
}
};
#endif
there you go, now you just need to include a.h to the files where you want to use this structure.

Employees.objects.values_list('eng_name', flat=True)
That creates a flat list of all eng_name

You need to create a file named org.apache.cxf.Logger
(that is: org.apache.cxf
file with Logger
extension) under /META-INF/cxf/
with the following contents:
org.apache.cxf.common.logging.Log4jLogger
Reference: Using Log4j Instead of java.util.logging.
Also if you replace standard:
<cxf:bus>
<cxf:features>
<cxf:logging/>
</cxf:features>
</cxf:bus>
with much more verbose:
<bean id="abstractLoggingInterceptor" abstract="true">

Apache CXF will pretty print XML messages formatting them with proper indentation and line breaks. Very useful. More about it here.

use App\Post;
and use the model class like this.
Route::get('/posts', function() {
$results = Post::all();
return $results; });
First you need to get a token from android and then you can call this php code and you can even send data for further actions in your app.
<?php
// Call .php?Action=M&t=title&m=message&r=token
$action=$_GET["Action"];
switch ($action) {
Case "M":
$r=$_GET["r"];
$t=$_GET["t"];
$m=$_GET["m"];
$j=json_decode(notify($r, $t, $m));
$succ=0;
$fail=0;
$succ=$j->{'success'};
$fail=$j->{'failure'};
print "Success: " . $succ . "<br>";
print "Fail : " . $fail . "<br>";
break;
default:
print json_encode ("Error: Function not defined ->" . $action);
}
function notify ($r, $t, $m)
{
// API access key from Google API's Console
if (!defined('API_ACCESS_KEY')) define( 'API_ACCESS_KEY', 'Insert here' );
$tokenarray = array($r);
// prep the bundle
$msg = array
(
'title' => $t,
'message' => $m,
'MyKey1' => 'MyData1',
'MyKey2' => 'MyData2',
);
$fields = array
(
'registration_ids' => $tokenarray,
'data' => $msg
);
$headers = array
(
'Authorization: key=' . API_ACCESS_KEY,
'Content-Type: application/json'
);
$ch = curl_init();
curl_setopt( $ch,CURLOPT_URL, 'fcm.googleapis.com/fcm/send' );
curl_setopt( $ch,CURLOPT_POST, true );
curl_setopt( $ch,CURLOPT_HTTPHEADER, $headers );
curl_setopt( $ch,CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch,CURLOPT_SSL_VERIFYPEER, false );
curl_setopt( $ch,CURLOPT_POSTFIELDS, json_encode( $fields ) );
$result = curl_exec($ch );
curl_close( $ch );
return $result;

There's no such concept as an integer with padding. How many legs do you have - 2, 02 or 002? They're the same number. Indeed, even the "2" part isn't really part of the number, it's only relevant in the decimal representation.
If you need padding, that suggests you're talking about the textual representation of a number... i.e. a string.
You can achieve that using string formatting options, e.g.
string text = value.ToString("0000000");
or
string text = value.ToString("D7");
HTTP is a connectionless and this is a direct result that HTTP is a stateless protocol. The server and client are aware of each other only during a current request. Afterwards, both of them forget about each other. Due to this nature of the protocol, neither the client nor the browser can retain information between different request across the web pages.
Perl Code for Unix systems:
# Capture date from shell
my $current_date = `date +"%m/%d/%Y"`;
# Remove newline character
$current_date = substr($current_date,0,-1);
print $current_date, "\n";
I've a solution for bash purists.
The function 'define' helps us to assign a multiline value to a variable. This one takes one positional parameter: the variable name to assign the value.
In the heredoc, optionally there're parameter expansions too!

php artisan migrate:fresh
Should do the job, if you are in development and the desired outcome is to start all over.
In production, that maybe not the desired thing, so you should be adverted. (The migrate:fresh command will drop all tables from the database and then execute the migrate command).
The FileUpload.AllowMultiple
property in .NET 4.5 and higher will allow you the control to select multiple files.
<asp:FileUpload ID="fileImages" AllowMultiple="true" runat="server" />
.NET 4 and below
<asp:FileUpload ID="fileImages" Multiple="Multiple" runat="server" />
On the post-back, you can then:
Dim flImages As HttpFileCollection = Request.Files
For Each key As String In flImages.Keys
Dim flfile As HttpPostedFile = flImages(key)
flfile.SaveAs(yourpath & flfile.FileName)
Next
the safest way is to put the ! for the regex negation within the [[ ]]
like this:
if [[ ! ${STR} =~ YOUR_REGEX ]]; then
otherwise it might fail on certain systems.
You can use a tool like the TrIDNet - File Identifier to look for the Magic Number and other telltales, if the file format is in it's database it may tell you what it is for.
However searching the definitions did not turn up anything for the string "FLDB", but it checks more than magic numbers so it is worth a try.
If you are using Linux File is a command that will do a similar task.
The other thing to try is if you have access to the program that generated this file, there may be DLL's or EXE's from the database software that may contain meta information about the dll's creator which could give you a starting point for looking for software that can read the file outside of the program that originally created the .db
file.
The root cause of this problem has to do with user authentication versions. For each database user, multiple password verifiers are kept in the database. Typically when you upgrade your database, a new password verifier will be added to the list, a stronger one. The following query shows the password verifier versions that are available for each user. For example:
SQL> SELECT PASSWORD_VERSIONS FROM DBA_USERS WHERE USERNAME='SCOTT';
PASSWORD_VERSIONS
-----------------
11G 12C
When upgrading to a newer driver you can use a newer version of the verifier because the driver and server negotiate the strongest possible verifier to to be used. This newer version of the verifier will be more secure and will involve generating larger random numbers or using more complex hashing functions which can explain why you see issues while establishing JDBC connections. As mentioned by other responses using /dev/urandom
normally resolves these issues. You can also decide to downgrade your password verifier and make the newer driver use the same older password verifier that your previous driver was using. For example if you want to use the 10G password verifier (for testing purposes only), first you need to make sure it's available for your user.
Set SQLNET.ALLOWED_LOGON_VERSION_SERVER=8
in sqlnet.ora on the server. Then:
SQL> alter user scott identified by "tiger";
User altered.
SQL> SELECT PASSWORD_VERSIONS FROM DBA_USERS WHERE USERNAME='SCOTT';
PASSWORD_VERSIONS
-----------------
10G 11G 12C
Then you can force the JDBC thin driver to use the 10G verifier by setting this JDBC property oracle.jdbc.thinLogonCapability="o3"
. If you run into the error "ORA-28040: No matching authentication protocol"
then that means your server is not allowing the 10G verifier to be used. If that's the case then you need to check your configuration again.
Well, since you asked for R equivalent to other languages, I tried to do this. Seems to work though I haven't really looked at which technique is more efficient in R.

For the categorical columns though, it would fetch you a Data Frame which you could typecast using as.character() if needed.
If you only need the index of a character the most simple, quick solution (as already pointed out by Pascal) is:
let index = string.characters.index(of: ".")
let intIndex = string.distance(from: string.startIndex, to: index)
Using sed:
T=$(printf "\t")
sed "s/[[:blank:]]\+/$T/g"
or
sed "s/[[:space:]]\+/$T/g"

Double click behaves as one single click
"It is inadvisable to bind handlers to both the click and dblclick events for the same element. The sequence of events triggered varies from browser to browser, with some receiving two click events before the dblclick and others only one. Double-click sensitivity (maximum time between clicks that is detected as a double click) can vary by operating system and browser, and is often user-configurable."
That way we have to check what is the event that is being executed at any sequence.

Gotta love those six different caught exceptions :). There are certainly some refactoring to simplify the code a bit. But, I like delfuego's -D options on the VM. I wish there was a javax.net.ssl.trustStore static property that I could just set. Just two lines of code and done. Anyone know where that would be?
This may be too much to ask, but, ideally the keytool would not be used. Instead, the trustedStore would be created dynamically by the code and the cert is added at runtime.
There must be a better answer.
You have at least two issues in your code:
ng-change="getScoreData(Score)
Angular doesn't see getScoreData
method that refers to defined service
getScoreData: function (Score, callback)
We don't need to use callback since GET
returns promise. Use then
instead.
Here is a working example (I used random address only for simulation):
HTML
<select ng-model="score"
ng-change="getScoreData(score)"
ng-options="score as score.name for score in scores"></select>
<pre>{{ScoreData|json}}</pre>
JS
var fessmodule = angular.module('myModule', ['ngResource']);
fessmodule.controller('fessCntrl', function($scope, ScoreDataService) {
$scope.scores = [{
name: 'Bukit Batok Street 1',
URL: 'http://maps.googleapis.com/maps/api/geocode/json?address=Singapore, SG, Singapore, 153 Bukit Batok Street 1&sensor=true'
}, {
name: 'London 8',
URL: 'http://maps.googleapis.com/maps/api/geocode/json?address=Singapore, SG, Singapore, London 8&sensor=true'
}];
$scope.getScoreData = function(score) {
ScoreDataService.getScoreData(score).then(function(result) {
$scope.ScoreData = result;
}, function(result) {
alert("Error: No data returned");
});
};
});
fessmodule.$inject = ['$scope', 'ScoreDataService'];
fessmodule.factory('ScoreDataService', ['$http', '$q', function($http) {
var factory = {
getScoreData: function(score) {
console.log(score);
var data = $http({
method: 'GET',
url: score.URL
});
return data;
}
}
return factory;
}]);

If I understand the question, then it seems to me that the questioner is really asking "OK, so 3-tier is well understood, but it seems that there's a mix of hype, confusion, and uncertainty around what 4-tier, or to generalize, N-tier architectures mean. So...what's a definition of N-tier that is widely understood and agreed upon?"
It's actually a fairly deep question, and to explain why, I need to go a little deeper. Bear with me.
The classic 3-tier architecture: database, "business logic" and presentation, is a good way to clarify how to honor the principle of separation of concerns. Which is to say, if I want to change how "the business" wants to service customers, I should not have to look through the entire system to figure out how to do this, and in particular, decisions business issues shouldn't be scattered willy-nilly through the code.
Now, this model served well for decades, and it is the classic 'client-server' model. Fast forward to cloud offerings, where web browsers are the user interface for a broad and physically distributed set of users, and one typically ends up having to add content distribution services, which aren't a part of the classic 3-tier architecture (and which need to be managed in their own right).
The concept generalizes when it comes to services, micro-services, how data and computation are distributed and so on. Whether or not something is a 'tier' largely comes down to whether or not the tier provides an interface and deployment model to services that are behind (or beneath) the tier. So a content distribution network would be a tier, but an authentication service would not be.
Now, go and read other descriptions of examples of N-tier architectures with this concept in mind, and you will begin to understand the issue. Other perspectives include vendor-based approaches (e.g. NGINX), content-aware load balancers, data isolation and security services (e.g. IBM Datapower), all of which may or may not add value to a given architecture, deployment, and use cases.

I just got this error again today as I updated my machine (with updates for PHP) running Ubuntu 14.04. The distribution config file /etc/php5/fpm/pool.d/www.conf
is fine and doesn't require any changes currently.
I found the following errors:

The strange thing was that I have 2 sites running that utilize PHP-FPM on this machine one was running fine and the other (a Tiny Tiny RSS installation) gave me a 502, where both have been running fine before.
I compared both configuration files and found that fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
was missing for the affected site.
Both configuration files now contain the following block and are running fine again:

Generally building with the NDK is as simple as correctly specifying an ndkBuild path to Android.mk or cmake path to CMakeLists.txt. I recommend CMake over the older Android.mk because Android Studio's C/C++ support is based upon CLion and it uses CMake as its project format. This in my experience has tended to make the IDE more responsive on larger projects. Everything compiled in your project will be built and copied into the APK automatically.
apply plugin: 'com.android.library'
android {
compileSdkVersion 19
buildToolsVersion "25.0.2"
defaultConfig {
minSdkVersion 19

// 64-bit support requires an Android API level higher than 19; Namely 21 and higher
//abiFilters 'armeabi', 'armeabi-v7a', 'arm64-v8a', 'x86', 'x86_64'

Static libraries (.a) in your NDK build will automatically be included, but prebuilt dynamic libraries (.so) will need to be placed in jniLibs
. This can be configured using sourceSets
, but you should adopt the standard. You DO NOT NEED any additional commands in build.gradle
when including prebuilt libraries.
jniLibs
You can find more information about the structure in the Android Gradle Plugin User Guide.
|--app: |--|--build.gradle |--|--src: |--|--|--main |--|--|--|--java |--|--|--|--jni |--|--|--|--|--CMakeLists.txt |--|--|--|--jniLibs |--|--|--|--|--armeabi |--|--|--|--|--|--.so Files |--|--|--|--|--armeabi-v7a |--|--|--|--|--|--.so Files |--|--|--|--|--x86 |--|--|--|--|--|--.so Files
You can then validate the resulting APK contains your .so files, typically under build/outputs/apk/
, using unzip -l myApp.apk
to list the contents.
If you're building a shared library in the NDK you do not need to do anything further. It will be correctly bundled in the APK.
Here is a solution handling all Unicode code points include upper (4 byte) values and supported by all modern browsers (IE and others > 5.5). It uses decodeURIComponent(), but NOT the deprecated escape/unescape functions:
function utf8_to_str(a) {
for(var i=0, s=''; i<a.length; i++) {
var h = a[i].toString(16)
if(h.length < 2) h = '0' + h
s += '%' + h
}
return decodeURIComponent(s)
}
Tested and available on GitHub
To create UTF-8 from a string:
function utf8_from_str(s) {
for(var i=0, enc = encodeURIComponent(s), a = []; i < enc.length;) {
if(enc[i] === '%') {
a.push(parseInt(enc.substr(i+1, 2), 16))
i += 3
} else {
a.push(enc.charCodeAt(i++))
}
}
return a

Since it is the sim code it also should not change when traveling to other countries.

var wysiwyg_clean = wysiwyg.replace('&', '%26');
As Wolfram points out, this is nicely handled (along with all the other special characters) by encodeURIComponent.
You will figure out that setOnPageChangeListener is deprecated, use addOnPageChangeListener, as below:
ViewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
}
@Override
public void onPageSelected(int position) {
if(position == 1){ // if you want the second page, for example
//Your code here
}
}
@Override
public void onPageScrollStateChanged(int state) {
}
});
It's perfectly possible to use both a color and an image as background for an element.
You set the background-color
and background-image
styles. If the image is smaller than the element, you need to use the background-position
style to place it to the right, and to keep it from repeating and covering the entire background you use the background-repeat
style:
background-color: green;
background-image: url(images/shadow.gif);
background-position: right;
background-repeat: no-repeat;
Or using the composite style background
:
background: green url(images/shadow.gif) right no-repeat;
If you use the composite style background
to set both separately, only the last one will be used, that's one possible reason why your color is not visible:
background: green; /* will be ignored */
background: url(images/shadow.gif) right no-repeat;
There is no way to specifically limit the background image to cover only part of the element, so you have to make sure that the image is smaller than the element, or that it has any transparent areas, for the background color to be visible.
Using HttpClient (Http's replacement) in Angular 4.3+, the entire mapping/casting process is made simpler/eliminated.
Using your CountryData class, you would define a service method like this:
getCountries() {
return this.httpClient.get<CountryData[]>('http://theUrl.com/all');
}
Then when you need it, define an array like this:
countries:CountryData[] = [];
and subscribe to it like this:
this.countryService.getCountries().subscribe(countries => this.countries = countries);
A complete setup answer is posted here also.
complete.cases
gives TRUE
when all values in a row are not NA

We use a script which checks if a running container is started with the latest image. We also use upstart init scripts for starting the docker image.
#!/usr/bin/env bash
set -e
BASE_IMAGE="registry"
REGISTRY="registry.hub.docker.com"
IMAGE="$REGISTRY/$BASE_IMAGE"
CID=$(docker ps | grep $IMAGE | awk '{print $1}')
docker pull $IMAGE
for im in $CID
do
LATEST=`docker inspect --format "{{.Id}}" $IMAGE`
RUNNING=`docker inspect --format "{{.Image}}" $im`
NAME=`docker inspect --format '{{.Name}}' $im | sed "s/\///g"`
echo "Latest:" $LATEST
echo "Running:" $RUNNING
if [ "$RUNNING" != "$LATEST" ];then
echo "upgrading $NAME"
stop docker-$NAME
docker rm -f $NAME
start docker-$NAME
else
echo "$NAME up to date"
fi
done
And init looks like
docker run -t -i --name $NAME $im /bin/bash
The thing about collations is that although the database has its own collation, every table, and every column can have its own collation. If not specified it takes the default of its parent object, but can be different.
When you change collation of the database, it will be the new default for all new tables and columns, but it doesn't change the collation of existing objects inside the database. You have to go and change manually the collation of every table and column.
Luckily there are scripts available on the internet that can do the job. I am not going to recommend any as I haven't tried them but here are few links:
http://www.codeproject.com/Articles/302405/The-Easy-way-of-changing-Collation-of-all-Database
Update Collation of all fields in database on the fly
http://www.sqlservercentral.com/Forums/Topic820675-146-1.aspx
If you need to have different collation on two objects or can't change collations - you can still JOIN
between them using COLLATE
command, and choosing the collation you want for join.
SELECT * FROM A JOIN B ON A.Text = B.Text COLLATE Latin1_General_CI_AS
or using default database collation:
SELECT * FROM A JOIN B ON A.Text = B.Text COLLATE DATABASE_DEFAULT
To let MySql generate sequence numbers for an AUTO_INCREMENT
field you have three options:
...No value was specified for the AUTO_INCREMENT column, so MySQL assigned sequence numbers automatically. You can also explicitly assign NULL or 0 to the column to generate sequence numbers.
These three statements will produce the same result:
$insertQuery = "INSERT INTO workorders (`priority`, `request_type`) VALUES('$priority', '$requestType', ...)";
$insertQuery = "INSERT INTO workorders VALUES(NULL, '$priority', ...)";
$insertQuery = "INSERT INTO workorders VALUES(0, '$priority', ...";
"I tried to figure out, why exactly we need Observer and Observable"
As previous answers already stated, they provide means of subscribing an observer to receive automatic notifications of an observable.
One example application where this may be useful is in data binding, let's say you have some UI that edits some data, and you want the UI to react when the data is updated, you can make your data observable, and subscribe your UI components to the data
Knockout.js is a MVVM javascript framework that has a great getting started tutorial, to see more observables in action I really recommend going through the tutorial. http://learn.knockoutjs.com/
I also found this article in Visual Studio 2008 start page (The Observer Pattern is the foundation of Model View Controller (MVC) development) http://visualstudiomagazine.com/articles/2013/08/14/the-observer-pattern-in-net.aspx
Try using qx{command}
rather than backticks. To me, it's a bit better because: you can do SQL with it and not worry about escaping quotes and such. Depending on the editor and screen, my old eyes tend to miss the tiny back ticks, and it shouldn't ever have an issue with being overloaded like using angle brackets versus glob.
Simple Get Request using HttpClient Class

var result = httpClient.GetAsync("https://www.google.com").Result;
}
}
Hi url should be calling a function which in return will give response
$.ajax({

try using/calling API facebook method
Easy way for older C++, or C:
#include <time.h> // includes clock_t and CLOCKS_PER_SEC
int main() {
clock_t start, end;
start = clock();
// ...code to measure...
end = clock();
double duration_sec = double(end-start)/CLOCKS_PER_SEC;
return 0;
}
Timing precision in seconds is 1.0/CLOCKS_PER_SEC
Not sure if this is still an issue for people, however... Using SystemJS and MomentJS as library, this solved it for me
/*
* Import Custom Components
*/
import * as moment from 'moment/moment'; // please use path to moment.js file, extension is set in system.config
// under systemjs, moment is actually exported as the default export, so we account for that
const momentConstructor: (value?: any) => moment.Moment = (<any>moment).default || moment;
Works fine from there for me.
I think this question is still relevant today. Using the C++11 standard you are now able to implement a instanceof
function without using dynamic_cast
like this:
if (dynamic_cast<B*>(aPtr) != nullptr) {
// aPtr is instance of B
} else {
// aPtr is NOT instance of B
}
But you're still reliant on RTTI
support. So here is my solution for this problem depending on some Macros and Metaprogramming Magic. The only drawback imho is that this approach does not work for multiple inheritance.
InstanceOfMacros.h
#include <set>
#include <tuple>
#include <typeindex>
#define _EMPTY_BASE_TYPE_DECL() using BaseTypes = std::tuple<>;
#define _BASE_TYPE_DECL(Class, BaseClass) \
using BaseTypes = decltype(std::tuple_cat(std::tuple<BaseClass>(), Class::BaseTypes()));
#define _INSTANCE_OF_DECL_BODY(Class) \
static const std::set<std::type_index> baseTypeContainer; \
virtual bool instanceOfHelper(const std::type_index &_tidx) { \
if (std::type_index(typeid(ThisType)) == _tidx) return true; \
if (std::tuple_size<BaseTypes>::value == 0) return false; \
return baseTypeContainer.find(_tidx) != baseTypeContainer.end(); \
} \
template <typename... T> \
static std::set<std::type_index> getTypeIndexes(std::tuple<T...>) { \
return std::set<std::type_index>{std::type_index(typeid(T))...}; \
}
#define INSTANCE_OF_SUB_DECL(Class, BaseClass) \
protected: \
using ThisType = Class; \
_BASE_TYPE_DECL(Class, BaseClass) \
_INSTANCE_OF_DECL_BODY(Class)
#define INSTANCE_OF_BASE_DECL(Class) \
protected: \
using ThisType = Class; \
_EMPTY_BASE_TYPE_DECL() \
_INSTANCE_OF_DECL_BODY(Class) \
public: \
template <typename Of> \
typename std::enable_if<std::is_base_of<Class, Of>::value, bool>::type instanceOf() { \
return instanceOfHelper(std::type_index(typeid(Of))); \
}
#define INSTANCE_OF_IMPL(Class) \
const std::set<std::type_index> Class::baseTypeContainer = Class::getTypeIndexes(Class::BaseTypes());
You can then use this stuff (with caution) as follows:
DemoClassHierarchy.hpp*
#include "InstanceOfMacros.h"
struct A {
virtual ~A() {}
INSTANCE_OF_BASE_DECL(A)
};
INSTANCE_OF_IMPL(A)
struct B : public A {
virtual ~B() {}
INSTANCE_OF_SUB_DECL(B, A)
};
INSTANCE_OF_IMPL(B)
struct C : public A {
virtual ~C() {}
INSTANCE_OF_SUB_DECL(C, A)
};
INSTANCE_OF_IMPL(C)
struct D : public C {
virtual ~D() {}
INSTANCE_OF_SUB_DECL(D, C)
};
INSTANCE_OF_IMPL(D)
The following code presents a small demo to verify rudimentary the correct behavior.
InstanceOfDemo.cpp
#include <iostream>
#include <memory>
#include "DemoClassHierarchy.hpp"
int main() {
A *a2aPtr = new A;
A *a2bPtr = new B;
std::shared_ptr<A> a2cPtr(new C);
C *c2dPtr = new D;
std::unique_ptr<A> a2dPtr(new D);
std::cout << "a2aPtr->instanceOf<A>(): expected=1, value=" << a2aPtr->instanceOf<A>() << std::endl;

delete a2aPtr;
delete a2bPtr;
delete c2dPtr;
return 0;
}
Output:

The most interesting question which now arises is, if this evil stuff is more efficient than the usage of dynamic_cast
. Therefore I've written a very basic performance measurement app.
InstanceOfPerformance.cpp
#include <chrono>
#include <iostream>
#include <string>
#include "DemoClassHierarchy.hpp"
template <typename Base, typename Derived, typename Duration>
Duration instanceOfMeasurement(unsigned _loopCycles) {
auto start = std::chrono::high_resolution_clock::now();
volatile bool isInstanceOf = false;
for (unsigned i = 0; i < _loopCycles; ++i) {
Base *ptr = new Derived;
isInstanceOf = ptr->template instanceOf<Derived>();
delete ptr;
}
auto end = std::chrono::high_resolution_clock::now();
return std::chrono::duration_cast<Duration>(end - start);
}
template <typename Base, typename Derived, typename Duration>
Duration dynamicCastMeasurement(unsigned _loopCycles) {
auto start = std::chrono::high_resolution_clock::now();
volatile bool isInstanceOf = false;
for (unsigned i = 0; i < _loopCycles; ++i) {
Base *ptr = new Derived;
isInstanceOf = dynamic_cast<Derived *>(ptr) != nullptr;
delete ptr;
}
auto end = std::chrono::high_resolution_clock::now();
return std::chrono::duration_cast<Duration>(end - start);
}
int main() {
unsigned testCycles = 10000000;
std::string unit = " us";
using DType = std::chrono::microseconds;
std::cout << "InstanceOf performance(A->D) : " << instanceOfMeasurement<A, D, DType>(testCycles).count() << unit
<< std::endl;
std::cout << "InstanceOf performance(A->C) : " << instanceOfMeasurement<A, C, DType>(testCycles).count() << unit
<< std::endl;
std::cout << "InstanceOf performance(A->B) : " << instanceOfMeasurement<A, B, DType>(testCycles).count() << unit
<< std::endl;
std::cout << "InstanceOf performance(A->A) : " << instanceOfMeasurement<A, A, DType>(testCycles).count() << unit
<< "\n"
<< std::endl;
std::cout << "DynamicCast performance(A->D) : " << dynamicCastMeasurement<A, D, DType>(testCycles).count() << unit
<< std::endl;
std::cout << "DynamicCast performance(A->C) : " << dynamicCastMeasurement<A, C, DType>(testCycles).count() << unit
<< std::endl;
std::cout << "DynamicCast performance(A->B) : " << dynamicCastMeasurement<A, B, DType>(testCycles).count() << unit
<< std::endl;
std::cout << "DynamicCast performance(A->A) : " << dynamicCastMeasurement<A, A, DType>(testCycles).count() << unit
<< "\n"
<< std::endl;
return 0;
}
The results vary and are essentially based on the degree of compiler optimization. Compiling the performance measurement program using g++ -std=c++11 -O0 -o instanceof-performance InstanceOfPerformance.cpp
the output on my local machine was:
InstanceOf performance(A->D) : 699638 us
InstanceOf performance(A->C) : 642157 us
InstanceOf performance(A->B) : 671399 us
InstanceOf performance(A->A) : 626193 us
DynamicCast performance(A->D) : 754937 us
DynamicCast performance(A->C) : 706766 us
DynamicCast performance(A->B) : 751353 us
DynamicCast performance(A->A) : 676853 us
Mhm, this result was very sobering, because the timings demonstrates that the new approach is not much faster compared to the dynamic_cast
approach. It is even less efficient for the special test case which tests if a pointer of A
is an instance ofA
. BUT the tide turns by tuning our binary using compiler otpimization. The respective compiler command is g++ -std=c++11 -O3 -o instanceof-performance InstanceOfPerformance.cpp
. The result on my local machine was amazing:
InstanceOf performance(A->D) : 3035 us
InstanceOf performance(A->C) : 5030 us
InstanceOf performance(A->B) : 5250 us
InstanceOf performance(A->A) : 3021 us
DynamicCast performance(A->D) : 666903 us
DynamicCast performance(A->C) : 698567 us
DynamicCast performance(A->B) : 727368 us
DynamicCast performance(A->A) : 3098 us
If you are not reliant on multiple inheritance, are no opponent of good old C macros, RTTI and template metaprogramming and are not too lazy to add some small instructions to the classes of your class hierarchy, then this approach can boost your application a little bit with respect to its performance, if you often end up with checking the instance of a pointer. But use it with caution. There is no warranty for the correctness of this approach.
Note: All demos were compiled using clang (Apple LLVM version 9.0.0 (clang-900.0.39.2))
under macOS Sierra on a MacBook Pro Mid 2012.
Edit:
I've also tested the performance on a Linux machine using gcc (Ubuntu 5.4.0-6ubuntu1~16.04.9) 5.4.0 20160609
. On this platform the perfomance benefit was not so significant as on macOs with clang.
Output (without compiler optimization):
InstanceOf performance(A->D) : 390768 us
InstanceOf performance(A->C) : 333994 us
InstanceOf performance(A->B) : 334596 us
InstanceOf performance(A->A) : 300959 us
DynamicCast performance(A->D) : 331942 us
DynamicCast performance(A->C) : 303715 us

Oleg's answer https://stackoverflow.com/a/42994192/9921853 is the best there. It allows to apply the tooltip styles to the dynamically created elements. However it doesn't work for Bootstrap 4. It should be slightly modified:
Bootstrap 3:
$(document).on('inserted.bs.tooltip', function(e) {
var tooltip = $(e.target).data('bs.tooltip');
tooltip.$tip.addClass($(e.target).data('tooltip-custom-class'));
});

As the messages above indicate, the List cannot be differentiated between a List<Object>
and a List<String>
or List<Integer>
.
I've solved this error message for a similar problem:
List<String> strList = (List<String>) someFunction();
String s = strList.get(0);
with the following:
List<?> strList = (List<?>) someFunction();
String s = (String) strList.get(0);
Explanation: The first type conversion verifies that the object is a List without caring about the types held within (since we cannot verify the internal types at the List level). The second conversion is now required because the compiler only knows the List contains some sort of objects. This verifies the type of each object in the List as it is accessed.

Bootstrap 4 (update 2019)
A multi-item carousel can be accomplished in several ways as explained here. Another option is to use separate thumbnails to navigate the carousel slides.
Bootstrap 3 (original answer)
This can be done using the grid inside each carousel item.
<div id="myCarousel" class="carousel slide">
<div class="carousel-inner">
<div class="item active">
<div class="row">
<div class="col-sm-3">..
</div>
<div class="col-sm-3">..
</div>
<div class="col-sm-3">..
</div>
<div class="col-sm-3">..
</div>
</div>
<!--/row-->
</div>
...add more item(s)
</div>
</div>
Demo example thumbnail slider using the carousel:

Another example with carousel indicators as thumbnails: http://www.bootply.com/79859
You should just use something like:
YourModel.update_all(
ActiveRecord::Base.send(:sanitize_sql_for_assignment, {:value => "'wow'"})
)
That would do the trick. Using the ActiveRecord::Base#send method to invoke the sanitize_sql_for_assignment makes the Ruby (at least the 1.8.7 version) skip the fact that the sanitize_sql_for_assignment is actually a protected method.
Style rules can be attached using:
Generally, I prefer to use linked style sheets because they:
However, your question is asking specifically about the style
tag versus inline styles. Prefer to use the style
tag, in this case, because it:
Inline elements only affect their respective element.
An important difference between the style
tag and the inline attribute is specificity. Specificity determines when one style overrides another. Generally, inline styles have a higher specificity.
Read CSS: Specificity Wars for an entertaining look at this subject.

More on Windows... variable java.home is not always the same location as the binary that is run.
As Denis The Menace says, the installer puts Java files into Program Files, but also java.exe into System32. With nothing Java related on the path java -version can still work. However when PeterMmm's program is run it reports the value of Program Files as java.home, this is not wrong (Java is installed there) but the actual binary being run is located in System32.
One way to hunt down the location of the java.exe binary, add the following line to PeterMmm's code to keep the program running a while longer:
try{Thread.sleep(60000);}catch(Exception e) {}
Compile and run it, then hunt down the location of the java.exe image. E.g. in Windows 7 open the task manager, find the java.exe entry, right click and select 'open file location', this opens the exact location of the Java binary. In this case it would be System32.
If you are happy to use a 3rd party library, you can do this with Pandas. The benefits include seamless access to specialized methods and row / column labeling:
import pandas as pd
list1 = [1, 2, 3]
list2 = [4, 5, 6]
list3 = [7, 8, 9]
df = pd.DataFrame(list(zip(*[list1, list2, list3]))).add_prefix('Col')
df.to_csv('file.csv', index=False)
print(df)
Col0 Col1 Col2
0 1 4 7
1 2 5 8
2 3 6 9
This will let you choose from email, whatsapp or whatever.
