In eclipse, Go to Project->Properties->Java build Path->Order and Export. If you are using multiple JREs, try like jdk and ibm. Order should start with jdk and then IBM. This is how my issue was resolved.
UPDATE January, 2017:
According to Can I use, the user-select
is currently supported in all browsers except Internet Explorer 9 and earlier versions (but sadly still needs a vendor prefix).
All of the correct CSS variations are:
.noselect {_x000D_
-webkit-touch-callout: none; /* iOS Safari */_x000D_
-webkit-user-select: none; /* Safari */_x000D_
-khtml-user-select: none; /* Konqueror HTML */_x000D_
-moz-user-select: none; /* Firefox */_x000D_
-ms-user-select: none; /* Internet Explorer/Edge */_x000D_
user-select: none; /* Non-prefixed version, currently_x000D_
supported by Chrome and Opera */_x000D_
}
_x000D_
<p>_x000D_
Selectable text._x000D_
</p>_x000D_
<p class="noselect">_x000D_
Unselectable text._x000D_
</p>
_x000D_
Note that it's a non-standard feature (i.e. not a part of any specification). It is not guaranteed to work everywhere, and there might be differences in implementation among browsers and in the future browsers can drop support for it.

From your IDE, create a remote debug configuration, configure it for the default JPDA Tomcat port which is port 8000.
From the command line:
Linux:
cd apache-tomcat/bin
export JPDA_SUSPEND=y
./catalina.sh jpda run
Windows:
cd apache-tomcat\bin
set JPDA_SUSPEND=y
catalina.bat jpda run
Execute the remote debug configuration from your IDE, and Tomcat will start running and you are now able to set breakpoints in the IDE.
Note:
The JPDA_SUSPEND=y
line is optional, it is useful if you want that Apache Tomcat doesn't start its execution until step 3 is completed, useful if you want to troubleshoot application initialization issues.
You can set the margin and padding of either an ol

I haven’t actually done anything with font-face
, so take this with a pinch of salt, but I don’t think there’s any way for the browser to definitively tell if a given web font installed on a user’s machine or not.
The user could, for example, have a different font with the same name installed on their machine. The only way to definitively tell would be to compare the font files to see if they’re identical. And the browser couldn’t do that without downloading your web font first.
Does Firefox download the font when you actually use it in a font
declaration? (e.g. h1 { font: 'DejaVu Serif';
)?
WITH NOCHECK
is used as well when one has existing data in a table that doesn't conform to the constraint as defined and you don't want it to run afoul of the new constraint that you're implementing...
I used this code to show the dialog at the bottom of the screen:
Dialog dlg = <code to create custom dialog>;
Window window = dlg.getWindow();
WindowManager.LayoutParams wlp = window.getAttributes();
wlp.gravity = Gravity.BOTTOM;
wlp.flags &= ~WindowManager.LayoutParams.FLAG_DIM_BEHIND;
window.setAttributes(wlp);
This code also prevents android from dimming the background of the dialog, if you need it. You should be able to change the gravity parameter to move the dialog about
private void showPictureialog() {
final Dialog dialog = new Dialog(this,
android.R.style.Theme_Translucent_NoTitleBar);
// Setting dialogview
Window window = dialog.getWindow();
window.setGravity(Gravity.CENTER);
window.setLayout(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
dialog.setTitle(null);
dialog.setContentView(R.layout.selectpic_dialog);
dialog.setCancelable(true);
dialog.show();
}
you can customize you dialog based on gravity and layout parameters change gravity and layout parameter on the basis of your requirenment
I just unchecked all, applied, checked all again, applied and it worked :) hopefully helps others.
If the service is running via brew, you can stop it using the following command:
brew services stop mongodb
I may be missing the point of your question here, and if so I apologize. But, if you're not going to be deleting any items only adding them, why not simply assign a variable to the next empty slot? Every time you add a new value to the array, just increment the value to point to the next one.
In C++ a better solution is to use the standard library type std::list< type >
, which also allows the array to grow dynamically, e.g.:
#include <list>
std::list<int> arr;
for (int i = 0; i < 10; i++)
{
// add new value from 0 to 9 to next slot
arr.push_back(i);
}
// add arbitrary value to the next free slot
arr.push_back(22);
You can also use "bold" and "italic" instead of "normal" here. "Verdana" can be used for fontname..
But another question is this: How do you set the color of the text You write?
Answer: You use the turtle.color() method or turtle.fillcolor(), like this:
turtle.fillcolor("blue")
or just:
turtle.color("orange")
These calls must come before the turtle.write() command..
there are two ways of doing it either you can use XML or Java for it. If it's static and requires no changes then you can initialize in XML.
android:drawableLeft="@drawable/cloud_up"
android:drawablePadding="5sp"
Now if you need to change the icons dynamically then you can do it by calling the icons based on the events
textViewContext.setText("File Uploaded");
textViewContext.setCompoundDrawablesWithIntrinsicBounds(R.drawable.uploaded, 0, 0, 0);
I had drawn a splash screen (32bpp BGRA) with "transparent" background color in VS2013 and put a pictureBox in a form for display. For me a combination of above answers worked:
public Form1()
{
InitializeComponent();
SetStyle(ControlStyles.SupportsTransparentBackColor, true);
this.BackColor = this.pictureBox1.BackColor;
this.TransparencyKey = this.pictureBox1.BackColor;
}
So make sure you use the same BackColor everywhere and set that color as the TransparencyKey.
The getChars
string method does not return a value, instead it dumps its result into your buffer (or destination) array. The index parameter describes the start offset in your destination array.
Try this link for a more verbose description of the getChars
method.
I agree with the others on this, I think substring would be a better way to handle what you're trying to accomplish.
Synchronized HashMap
:
Each method is synchronized using an object level lock. So the get and put methods on synchMap acquire a lock.
Locking the entire collection is a performance overhead. While one thread holds on to the lock, no other thread can use the collection.
ConcurrentHashMap
was introduced in JDK 5.
There is no locking at the object level,The locking is at a much finer granularity. For a ConcurrentHashMap
, the locks may be at a hashmap bucket level.
The effect of lower level locking is that you can have concurrent readers and writers which is not possible for synchronized collections. This leads to much more scalability.
ConcurrentHashMap
does not throw a ConcurrentModificationException
if one thread tries to modify it while another is iterating over it.
This article Java 7: HashMap vs ConcurrentHashMap is a very good read. Highly recommended.
a bit late to the party but here's my solution:
<td style="padding: 0; position: relative;">
<div style="width: 100%; height: 100%; position: absolute; overflow: auto;">
AaaaaaaaaaaaaaaaaaBBBBBBBbbbbbbbCCCCCCCCCccccc<br>
DDDDDDDddddEEEEEEEEdddfffffffffgggggggggggggggggggg
</div>
</td>
There is a rather clever solution:
#define MACRO(X,Y) \
do { \
cout << "1st arg is:" << (X) << endl; \
cout << "2nd arg is:" << (Y) << endl; \
cout << "Sum is:" << ((X)+(Y)) << endl; \
} while (0)
Now you have a single block-level statement, which must be followed by a semicolon. This behaves as expected and desired in all three examples.
I had the exact same problem when I tried to compile OpenCV with Qt Creator (MinGW) to build the .a static library files.
For those that installed Qt 5.2.1 for Windows 32-bit (MinGW 4.8, OpenGL, 634 MB), this problem can be fixed if you add the following to the system's environment variable Path
:
C:\Qt\Qt5.2.0\Tools\mingw48_32\bin
Sometime only this helps:
View child = parent.findViewById(R.id.btnMoreText);
child.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
View parent = (View) v.getParent();
parent.performClick();
}
});
Another variant, works not always:
child.setOnClickListener(null);
do like this :
child{
position:absolute;
margin: auto;
top: 0;
bottom: 0;
left: 0;
right: 0;
}
extension String {
func firstCharacterUpperCase() -> String? {

}
}
let x = "heLLo"
let m = x.firstCharacterUpperCase()
For Swift 5:
extension String {
func firstCharacterUpperCase() -> String? {
guard !isEmpty else { return nil }
let lowerCasedString = self.lowercased()
return lowerCasedString.replacingCharacters(in: lowerCasedString.startIndex...lowerCasedString.startIndex, with: String(lowerCasedString[lowerCasedString.startIndex]).uppercased())

I don't see what the problem with the timeit
module is. This is probably the simplest way to do it.
import timeit
timeit.timeit(a, number=1)
Its also possible to send arguments to the functions. All you need is to wrap your function up using decorators. More explanation here: http://www.pythoncentral.io/time-a-python-function/
The only case where you might be interested in writing your own timing statements is if you want to run a function only once and are also want to obtain its return value.
The advantage of using the timeit
module is that it lets you repeat the number of executions. This might be necessary because other processes might interfere with your timing accuracy. So, you should run it multiple times and look at the lowest value.
If you want to reassign an element in an array, you can do the following:
var blah = ['Jan', 'Fed', 'Apr'];
console.log(blah);
function reassign(array, index, newValue) {
array[index] = newValue;
return array;
}
reassign(blah, [2], 'Mar');
If you are using Spring4/SpringBoot 1.x, then it's worth mentioning that you can add "text" (json) parts as well . This can be done via MockMvcRequestBuilders.fileUpload().file(MockMultipartFile file) (which is needed as method .multipart()
is not available in this version):
@Test
public void test() throws Exception {
mockMvc.perform(
MockMvcRequestBuilders.fileUpload("/files")
// file-part
.file(makeMultipartFile( "file-part" "some/path/to/file.bin", "application/octet-stream"))
// text part
.file(makeMultipartTextPart("json-part", "{ \"foo\" : \"bar\" }", "application/json"))
.andExpect(status().isOk())));
}
private MockMultipartFile(String requestPartName, String filename,
String contentType, String pathOnClassPath) {
return new MockMultipartFile(requestPartName, filename,
contentType, readResourceFile(pathOnClasspath);
}
// make text-part using MockMultipartFile
private MockMultipartFile makeMultipartTextPart(String requestPartName,
String value, String contentType) throws Exception {
return new MockMultipartFile(requestPartName, "", contentType,
value.getBytes(Charset.forName("UTF-8")));
}
private byte[] readResourceFile(String pathOnClassPath) throws Exception {
return Files.readAllBytes(Paths.get(Thread.currentThread().getContextClassLoader()
.getResource(pathOnClassPath).toUri()));
}
}

If you don't want to use regular expressions, you can try this:
$str = 'domain-name';
if (ctype_alnum(str_replace('-', '', $str)) && $str[0] != '-' && $str[strlen($str) - 1] != '-') {
echo "Valid domain\n";
} else {
echo "Invalid domain\n";
}
but as said regexp are the best tool for this.
Actually in case if you have any file that has key value pairs like this:
someKey=someValue
someOtherKey=someOtherValue
You can import that into webpack by a npm module called properties-reader
I found this really helpful since I'm integrating react with Java Spring framework where there is already an application.properties file. This helps me to keep all config together in one place.
"properties-reader": "0.0.16"
const PropertiesReader = require('properties-reader');
const appProperties = PropertiesReader('Path/to/your/properties.file')._properties;
externals: {
'Config': JSON.stringify(appProperties)
}
var Config = require('Config')
fetchData(Config.serverUrl + '/Enterprises/...')
#include <stdio.h>
#include <string.h>
int main() {
char src[] = "SexDrugsRocknroll";
char dest[5] = { 0 }; // 4 chars + terminator */
int len = strlen(src);
int i = 0;
while (i*4 < len) {
strncpy(dest, src+(i*4), 4);
i++;
printf("loop %d : %s\n", i, dest);
}
}
This refers to the object you’re “in” right now. In other words,this refers to the receiving object. You use this to clarify which variable you’re referring to.Java_whitepaper page :37
class Point extends Object
{
public double x;
public double y;
Point()
{
x = 0.0;
y = 0.0;
}
Point(double x, double y)
{
this.x = x;
this.y = y;
}
}
In the above example code this.x/this.y refers to current class that is Point class x and y variables where (double x,double y) are double values passed from different class to assign values to current class .
I think you are looking for $evalAsync http://docs.angularjs.org/api/ng.$rootScope.Scope#$evalAsync
Despite that the other answers are correct and thoroughly explained, I found some difficulties understanding them. Here is the method I used (Taken from here):
openssl pkcs12 -in filename.pfx -out cert.pem -nodes
Extracts the private key form a PFX to a PEM file:
openssl pkcs12 -in filename.pfx -nocerts -out key.pem
Exports the certificate (includes the public key only):
openssl pkcs12 -in filename.pfx -clcerts -nokeys -out cert.pem
Removes the password (paraphrase) from the extracted private key (optional):
openssl rsa -in key.pem -out server.key
Is there a step missing?
Yes. You need to create the directory:
mkdir ${HOME}/.ssh
Additionally, SSH requires you to set the permissions so that only you (the owner) can access anything in ~/.ssh:
% chmod 700 ~/.ssh
Should the
.ssh
dir be generated when I use thessh-keygen
command?
No. This command generates an SSH key pair but will fail if it cannot write to the required directory:
% ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/xxx/.ssh/id_rsa): /Users/tmp/does_not_exist
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
open /Users/tmp/does_not_exist failed: No such file or directory.
Saving the key failed: /Users/tmp/does_not_exist.
Once you've created your keys, you should also restrict who can read those key files to just yourself:
% chmod -R go-wrx ~/.ssh/*
The following is a hybrid jQuery solution that formats each data "record" into an HTML element and uses the data's properties as HTML attribute values.
The jquery each
runs the inner loop; I needed the regular JavaScript for
on the outer loop to be able to grab the property name (instead of value) for display as the heading. According to taste it can be modified for slightly different behaviour.
This is only 5 main lines of code but wrapped onto multiple lines for display:
$.get("data.php", function(data){
for (var propTitle in data) {
$('<div></div>')
.addClass('heading')
.insertBefore('#contentHere')
.text(propTitle);
$(data[propTitle]).each(function(iRec, oRec) {
$('<div></div>')
.addClass(oRec.textType)
.attr('id', 'T'+oRec.textId)
.insertBefore('#contentHere')
.text(oRec.text);
});
}
});
Produces the output
(Note: I modified the JSON data text values by prepending a number to ensure I was displaying the proper records in the proper sequence - while "debugging")
<div class="heading">

More Info
The JSON data was used in the following way:
for each category (key name the array is held under):
for each object held inside an array:
Give the #under
a negative z-index
, e.g. -1
This happens because the z-index
property is ignored in position: static;
, which happens to be the default value; so in the CSS code you wrote, z-index
is 1
for both elements no matter how high you set it in #over
.
By giving #under
a negative value, it will be behind any z-index: 1;
element, i.e. #over
.
This fixed the problem by having it as the first two lines of the script:
!pip install opencv-python
!apt update && apt install -y libsm6 libxext6
!apt-get install -y libxrender-dev
Go to "%TOMCAT_FOLDER%/conf/tomcat-users.xml" and configure the following :
<tomcat-users>
<role rolename="manager-gui"/>
<role rolename="manager-script"/>
<role rolename="manager-jmx"/>
<role rolename="manager-status"/>
<role rolename="admin"/>
<user username="admin" password="admin" roles="admin,manager-gui,manager-script"/>
</tomcat-users>
Hence, the username is "admin" and password is "admin"
Use:
netstat -a -o
This shows the PID of the process running on a particular port.
Keep in mind the process ID and go to Task Manager and services or details tab and end the process which has the same PID.
Thus you can kill a process running on a particular port in Windows.
The idea is that the response body gives you a page that links you to the thing:
201 Created
The 201 (Created) status code indicates that the request has been fulfilled and has resulted in one or more new resources being created. The primary resource created by the request is identified by either a Location header field in the response or, if no Location field is received, by the effective request URI.
This means that you would include a Location
in the response header that gives the URL of where you can find the newly created thing:
HTTP/1.1 201 Created
Date: Sat, 02 Apr 2016 12:22:40 GMT
Location: http://stackoverflow.com/a/36373586/12597
They then go on to mention what you should include in the response body:
The 201 response payload typically describes and links to the resource(s) created.
For the human using the browser, you give them something they can look at, and click, to get to their newly created resource:

The response is entirely up to you; it's arbitrarily what you'd like.
Finally there's the optimization that I can pre-cache the created resource (because I already have the content; I just uploaded it). The server can return a date or ETag which I can store with the content I just uploaded:
See Section 7.2 for a discussion of the meaning and purpose of validator header fields, such as ETag and Last-Modified, in a 201 response.

And ETag
s are purely arbitrary values. Having them be different when a resource changes (and caches need to be updated) is all that matters. The ETag is usually a hash (e.g. SHA2). But it can be a database rowversion
, or an incrementing revision number. Anything that will change when the thing changes.
They are as they were. That one key is JUST DELETED
One other way, using the splat operator:
*a, last = [1, 3, 4, 5]
STDOUT:
a: [1, 3, 4]
last: 5
Correct rounding is likely desired.
Therefore math.Round() is your quick(!) friend. Approaches with fmt.Sprintf and strconv.Atois() were 2 orders of magnitude slower according to my tests with a matrix of float64 values that were intended to become correctly rounded int values.
package main
import (
"fmt"
"math"
)
func main() {
var x float64 = 5.51
var y float64 = 5.50
var z float64 = 5.49
fmt.Println(int(math.Round(x))) // outputs "6"
fmt.Println(int(math.Round(y))) // outputs "6"
fmt.Println(int(math.Round(z))) // outputs "5"
}
math.Round() does return a float64 value but with int() applied afterwards, I couldn't find any mismatches so far.
There are several good points made here, but multiple return points can be unreadable as well, if the method is very lengthy. That being said, if you're going to use multiple return points just make sure that your method is short, otherwise the readability bonus of multiple return points may be lost.
This started as a comment on RGB's solution but I could not fit it in so have converted it to an answer. The inspiration for which is entirely RGB's.
RGB's solution worked for me. However, I wished to note a couple of points which may help others arriving at this post (like me) who are not that familiar which SVG and who may very well have generated their SVG file from a graphics package (as I had).
So to apply RGB's solutions I used:
The CSS
<style>
rect.btn {
stroke:#fff;
fill:#fff;
fill-opacity:0;
stroke-opacity:0;
}
</style>
The jquery script
<script type="text/javascript" src="../_public/_jquery/jquery-1.7.1.js"></script>
<script type="text/javascript">
$("document").ready(function(){
$(".btn").bind("click", function(event){alert("clicked svg")});
});
</script>
The HTML to code the inclusion of your pre-existing SVG file in the group tag inside the SVG code.
<div>
<svg xmlns="http://www.w3.org/2000/svg" version="1.1">
<g>
<image x="0" y="0" width="10" height="10"
xlink:href="../_public/_icons/booked.svg" width="10px"/>
<rect class="btn" x="0" y="0" width="10" height="10"/>
</g>
</svg>
</div>
However, in my case I have several SVG icons which I wish to be clickable and incorporating each of these into the SVG tag was starting to become cumbersome.
So as an alternative approach where I could employ Classes I used jquery.svg. This is probably a shameful application of this plugin which can do all sorts of stuff with SVG's. But it worked using the following code:
<script type="text/javascript" src="../_public/_jquery/jquery-1.7.1.js"></script>
<script type="text/javascript" src="jquery.svg.min.js"></script>
<script type="text/javascript">
$("document").ready(function(){
$(".svgload").bind("click", function(event){alert("clicked svg")});
for (var i=0; i < 99; i++) {
$(".svgload:eq(" + i + ")").svg({
onLoad: function(){
var svg = $(".svgload:eq(" + i + ")").svg('get');
svg.load("../_public/_icons/booked.svg", {addTo: true, changeSize: false});
},
settings: {}}
);
}
});
</script>
where HTML
<div class="svgload" style="width: 10px; height: 10px;"></div>
The advantage to my thinking is that I can use the appropriate class where ever the icons are needed and avoid quite a lot of code in the body of the HTML which aids readability. And I only need to incorporate the pre-existing SVG file once.
Edit: Here is a neater version of the script courtesy of Keith Wood: using .svg's load URL setting.
<script type="text/javascript" src="../_public/_jquery/jquery-1.7.1.js"></script>
<script type="text/javascript" src="jquery.svg.min.js"></script>
<script type="text/javascript">
$("document").ready(function(){
$('.svgload').on('click', function() {
alert('clicked svg new');
}).svg({loadURL: '../_public/_icons/booked.svg'});
});
</script>
class Tree(dict):
"""A tree implementation using python's autovivification feature."""
def __missing__(self, key):
value = self[key] = type(self)()
return value
#cast a (nested) dict to a (nested) Tree class
def __init__(self, data={}):
for k, data in data.items():
if isinstance(data, dict):
self[k] = type(self)(data)
else:
self[k] = data
works as a dictionary, but provides as many nested dicts you want. Try the following:
your_tree = Tree()
your_tree['a']['1']['x'] = '@'
your_tree['a']['1']['y'] = '#'
your_tree['a']['2']['x'] = '$'
your_tree['a']['3'] = '%'
your_tree['b'] = '*'
will deliver a nested dict ... which works as a tree indeed.
{'a': {'1': {'x': '@', 'y': '#'}, '2': {'x': '$'}, '3': '%'}, 'b': '*'}
... If you have already a dict, it will cast each level to a tree:
d = {'foo': {'amy': {'what': 'runs'} } }
tree = Tree(d)
print(d['foo']['amy']['what']) # returns 'runs'
d['foo']['amy']['when'] = 'now' # add new branch
In this way, you can keep edit/add/remove each dict level as you wish. All the dict methods for traversal etc, still apply.
You may try this:
Cookie::queue($name, $value, $minutes);
This will queue the cookie to use it later and later it will be added with the response when response is ready to be sent. You may check the documentation on Laravel
website.
Update (Retrieving A Cookie Value
):
$value = Cookie::get('name');
Note: If you set a cookie in the current request then you'll be able to retrieve it on the next subsequent request.
I find using pandas MultiIndex to be the best tool for the job. If you have a list of lists lists_list
, call pd.MultiIndex.from_product(lists_list)
and iterate over the result (or use it in DataFrame index).
Try this code refer from here
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js">
</script>
<script type="text/javascript" src="//cdnjs.cloudflare.com/ajax/libs/jstimezonedetect/1.0.4/jstz.min.js">

<script type="text/javascript">
$(document).ready(function(){
var tz = jstz.determine(); // Determines the time zone of the browser client
var timezone = tz.name(); //'Asia/Kolhata' for Indian Time.
alert(timezone);
});
</script>
Try this
function removeElements(){
$('#models').html("");
}
Yea, as everyone else wrote, you cannot do multiple inheritance in Java.
If you have two classes from which you'd like to use code, you'd typically just subclass one (say class A
). For class B
, you abstract the important methods of it to an interface BInterface
(ugly name, but you get the idea), then say Main extends A implements BInterface
. Inside, you can instantiate an object of class B
and implement all methods of BInterface
by calling the corresponding functions of B
.
This changes the "is-a" relationship to a "has-a" relationship as your Main
now is an A
, but has a B
. Depending on your use case, you might even make that change explicit by removing the BInterface
from your A
class and instead provide a method to access your B object directly.
You need to add:
#include <cstdlib>
in order for the compiler to see the prototype for system()
.
Error:Execution failed for task com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException:
finished with non-zero exit value 1
One reason for this error to occure is that the file path to a resource file is to long:
Error: File path too long on Windows, keep below 240 characters
Fix: Move your project folder closer to the root of your disk
Don't:// folder/folder/folder/folder/very_long_folder_name/MyProject...
Do://folder/short_name/MyProject
Another reason could be duplicated resources or name spaces
Example:
<style name="MyButton" parent="android:Widget.Button">
<item name="android:textColor">@color/accent_color</item>
<item name="android:textColor">#000000</item>
</style>
And make sure all file names and extensions are in lowercase

I am generally a proponent of putting everything in stored procedures, for all of the reasons DBAs have been harping on for years. In the case of Linq, it is true that there will be no performance difference with simple CRUD queries.
But keep a few things in mind when making this decision: using any ORM couples you tightly to your data model. A DBA has no freedom to make changes to the data model without forcing you to change your compiled code. With stored procedures, you can hide these sorts of changes to an extent, since the parameter list and results set(s) returned from a procedure represent its contract, and the innards can be changed around, just so long as that contract is still met.
And also, if Linq is used for more complex queries, tuning the database becomes a much more difficult task. When a stored procedure is running slow, the DBA can totally focus on the code in isolation, and has lots of options, just so that contract is still satisfied when he/she is done.
I have seen many, many cases where serious problems in an application were addressed by changes to the schema and code in stored procedures without any change to deployed, compiled code.
Perhaps a hybird approach would be nice with Linq? Linq can, of course, be used to call stored procedures.
You may define your enum
like so and use cast where needed
public enum MyEnum
{
VariablePeriods = 1,
FixedPeriods = 2
}
Usage
public class Entity
{
public MyEnum Property { get; set; }
}
var returnedFromDB = 1;
var entity = new Entity();
entity.Property = (MyEnum)returnedFromDB;
Add this class to your project
import android.content.Context;
import android.provider.Settings;
import android.text.TextUtils;
import com.google.android.gms.ads.AdRequest;
import java.io.UnsupportedEncodingException;
public class AdsHelper {

AdRequest.Builder adRequest = new AdRequest.Builder();
adRequest.addTestDevice(AdRequest.DEVICE_ID_EMULATOR);
if (BuildConfig.DEBUG) {
String deviceId = MD5(getDeviceId(context));
if (!TextUtils.isEmpty(deviceId)) {
adRequest.addTestDevice(deviceId.toUpperCase());
}
}
return adRequest.build();
}
private static String MD5(String md5) {
if (TextUtils.isEmpty(md5)) return null;
try {
java.security.MessageDigest md = java.security.MessageDigest.getInstance("MD5");
byte[] array = md.digest(md5.getBytes("UTF-8"));
StringBuilder sb = new StringBuilder();

}
private static String getDeviceId(Context context) {
try {
return Settings.Secure.getString(context.getContentResolver(), Settings.Secure.ANDROID_ID);
} catch (Exception e) {

See my answer to "What is a monad?"
It begins with a motivating example, works through the example, derives an example of a monad, and formally defines "monad".
It assumes no knowledge of functional programming and it uses pseudocode with function(argument) := expression
syntax with the simplest possible expressions.
This C++ program is an implementation of the pseudocode monad. (For reference: M
is the type constructor, feed
is the "bind" operation, and wrap
is the "return" operation.)
#include <iostream>
#include <string>
template <class A> class M
{
public:
A val;
std::string messages;
};
template <class A, class B>
M<B> feed(M<B> (*f)(A), M<A> x)
{
M<B> m = f(x.val);
m.messages = x.messages + m.messages;
return m;
}
template <class A>
M<A> wrap(A x)
{
M<A> m;
m.val = x;
m.messages = "";
return m;
}
class T {};
class U {};
class V {};
M<U> g(V x)
{
M<U> m;
m.messages = "called g.\n";
return m;
}
M<T> f(U x)
{
M<T> m;
m.messages = "called f.\n";
return m;
}
int main()
{
V x;
M<T> m = feed(f, feed(g, wrap(x)));
std::cout << m.messages;
}
One equivalent of lsof could be combined output from Sysinternals' handle and listdlls, i.e.:
c:\SysInternals>handle
[...]
------------------------------------------------------------------------------
gvim.exe pid: 5380 FOO\alois.mahdal
10: File (RW-) C:\Windows
1C: File (RW-) D:\some\locked\path\OpenFile.txt
[...]
c:\SysInternals>listdlls
[...]
------------------------------------------------------------------------------
Listdlls.exe pid: 6840
Command line: listdlls
Base Size Version Path

c:\SysInternals>listdlls
Unfortunately, you have to "run as Administrator" to be able to use them.
Also listdlls and handle do not produce continuous table-like form so filtering filename would hide PID. findstr /c:pid: /c:<filename>
should get you very close with both utilities, though
c:\SysinternalsSuite>handle | findstr /c:pid: /c:Driver.pm
System pid: 4 \<unable to open process>
smss.exe pid: 308 NT AUTHORITY\SYSTEM
avgrsa.exe pid: 384 NT AUTHORITY\SYSTEM

cmd.exe pid: 7140 FOO\alois.mahdal
conhost.exe pid: 1212 FOO\alois.mahdal
gvim.exe pid: 3408 FOO\alois.mahdal
188: File (RW-) D:\some\locked\path\OpenFile.txt
taskmgr.exe pid: 6016 FOO\alois.mahdal

Here we can see that gvim.exe is the one having this file open.
You can try ng-file-upload angularjs plugin (instead of ng-upload).
It's fairly easy to setup and deal with angularjs specifics. It also supports progress, cancel, drag and drop and is cross browser.

<script src="ng-file-upload.min.js"></script>
<div ng-controller="MyCtrl">
<input type="file" ngf-select="onFileSelect($files)" multiple>
</div>
JS:
//inject angular file upload directives and service.
angular.module('myApp', ['ngFileUpload']);
var MyCtrl = [ '$scope', '$upload', function($scope, $upload) {
$scope.onFileSelect = function($files) {
//$files: an array of files selected, each file has name, size, and type.
for (var i = 0; i < $files.length; i++) {
var file = $files[i];
$scope.upload = $upload.upload({

Mark Cidade's answer is right - you need to supply a tuple.
However from Python 2.6 onwards you can use format
instead of %
:
'{0} in {1}'.format(unicode(self.author,'utf-8'), unicode(self.publication,'utf-8'))
Usage of %
for formatting strings is no longer encouraged.
This method of string formatting is the new standard in Python 3.0, and should be preferred to the % formatting described in String Formatting Operations in new code.
There is no way to display interactive elements on the lockscreen or wallpaper with a non jailbroken iPhone.
I would recommend Countdown Widget it's free an you can display countdowns in the notification center which you can also access from your lockscreen.
I wrote a package (https://github.com/alexsanjoseph/compareDF) since I had the same issue.

qsec = c(16.46, 17.02, 33.00, 19.44, 15.84, 20.00))
df2 = data.frame(id1 = c("Mazda RX4", "Mazda RX4 Wag", "Datsun 710",
"Hornet 4 Drive", " Hornet Sportabout", "Valiant"),
id2 = c("Maz", "Maz", "Dat", "Hor", "Dus", "Val"),

volatile
[About] => synchronized
synchronized
block in Java is a monitor in multithreading. synchronized
block with the same object/class can be executed by only single thread, all others are waiting. It can help with race condition
situation when several threads try to update the same variable.
Java 5
extended synchronized
by supporting happens-before
[About]
An unlock (synchronized block or method exit) of a monitor happens-before every subsequent lock (synchronized block or method entry) of that same monitor.
The next step is java.util.concurrent
AtomicBoolean
The succinct Answer by NPE sums up your three options. I'll add some example code for the second item listed there: AtomicBoolean
.
You can think of the AtomicBoolean
class as providing some thread-safety wrapping around a boolean
value.
If you instantiate the AtomicBoolean
only once, then you need not worry about the visibility issue in the Java Memory Model that requires volatile
as a solution (the first item in that other Answer). Also, you need not concern yourself with synchronization (the third item in that other Answer) because AtomicBoolean
performs that function of protecting multi-threaded access to its internal boolean value.
Let's look at some example code.
Firstly, in modern Java we generally do not address the Thread
class directly. We now have the Executors framework to simplify handling of threads.
This code below is using Project Loom technology, coming to a future version of Java. Preliminary builds available now, built on early-access Java 16. This makes for simpler coding, with ExecutorService
being AutoCloseable
for convenient use with try-with-resources syntax. But Project Loom is not related to the point of this Answer; it just makes for simpler code that is easier to understand as “structured concurrency”.
The idea here is that we have three threads: the original thread, plus a ExecutorService
that will create two more threads. The two new threads both report the value of our AtomicBoolean
. The first new thread does so immediately, while the other waits 10 seconds before reporting. Meanwhile, our main thread sleeps for 5 seconds, wakes, changes the AtomicBoolean
object’s contained value, and then waits for that second thread to wake and complete its work the report on the now-altered AtomicBoolean
contained value. While we are installing seconds between each event, this is merely for dramatic demonstration. The real point is that these threads could coincidently try to access the AtomicBoolean
simultaneously, but that object will protect access to its internal boolean value in a thread-safe manner. Protecting against simultaneous access is the job of the Atomic…
classes.
try (
ExecutorService executorService = Executors.newVirtualThreadExecutor() ;
)
{
AtomicBoolean flag = new AtomicBoolean( true );
// This task, when run, will immediately report the flag.
Runnable task1 = ( ) -> System.out.println( "First task reporting flag = " + flag.get() + ". " + Instant.now() );
// This task, when run, will wait several seconds, then report the flag. Meanwhile, code below waits a shorter time before *changing* the flag.
Runnable task2 = ( ) -> {
try { Thread.sleep( Duration.ofSeconds( 10 ) ); } catch ( InterruptedException e ) { e.printStackTrace(); }
System.out.println( "Second task reporting flag = " + flag.get() + ". " + Instant.now() );
};
executorService.submit( task1 );
executorService.submit( task2 );
// Wait for first task to complete, so sleep here briefly. But wake before the sleeping second task awakens.
try { Thread.sleep( Duration.ofSeconds( 5 ) ); } catch ( InterruptedException e ) { e.printStackTrace(); }
System.out.println( "INFO - Original thread waking up, and setting flag to false. " + Instant.now() );
flag.set( false );
}
// At this point, with Project Loom technology, the flow-of-control blocks until the submitted tasks are done.
// Also, the `ExecutorService` is automatically closed/shutdown by this point, via try-with-resources syntax.
System.out.println( "INFO - Tasks on background threads are done. The `AtomicBoolean` and threads are gone." + Instant.now() );
Methods such as AtomicBoolean#get
and AtomicBoolean#set
are built to be thread-safe, to internally protect access to the boolean value nested within. Read up on the various other methods as well.
When run:
First task reporting flag = true. 2021-01-05T06:42:17.367337Z
INFO - Original thread waking up, and setting flag to false. 2021-01-05T06:42:22.367456Z
Second task reporting flag = false. 2021-01-05T06:42:27.369782Z
INFO - Tasks on background threads are done. The `AtomicBoolean` and threads are gone.2021-01-05T06:42:27.372597Z
Pro Tip: When engaging in threaded code in Java, always study the excellent book, Java Concurrency in Practice by Brian Goetz et al.
What you are after is called partial function application.
Don't be fooled by those that don't understand the subtle difference between that and currying, they are different.
Partial function application can be used to implement, but is not currying. Here is a quote from a blog post on the difference:
Where partial application takes a function and from it builds a function which takes fewer arguments, currying builds functions which take multiple arguments by composition of functions which each take a single argument.
This has already been answered, see this question for your answer: How can I pre-set arguments in JavaScript function call?
Example:
var fr = partial(f, 1, 2, 3);
// now, when you invoke fr() it will invoke f(1,2,3)
fr();
Again, see that question for the details.

I foolishly had a wrapper div which had a width measured in pixels. The other browsers seemed to be intelligent enough to deal with this. Once I had converted the width to a percentage value, it worked fine on Safari mobile as well. Very annoying.

x ~= 0 or 1
is the same as ((x ~= 0) or 1)
x ~=(0 or 1)
is the same as (x ~= 0)
.
try something like this instead.
function isNot0Or1(x)
return (x ~= 0 and x ~= 1)
end
print( isNot0Or1(-1) == true )
print( isNot0Or1(0) == false )
print( isNot0Or1(1) == false )
Your string is invalid, but assuming it was valid, you'd have to do:
var finalData = str.replace(/\\/g, "");
When you want to replace all the occurences with .replace
, the first parameter must be a regex, if you supply a string, only the first occurrence will be replaced, that's why your replace wouldn't work.

The only solution you have right now is to parse the HTML, build up some nodes with given point/font/etc attributes, then combine them together into an NSAttributedString. It's a lot of work, but if done correctly, can be reusable in the future.

General opinion seems to be that you should use whatever you're comfortable with.
Pretty sure pk_OrderID is the PK of AC_Shipping_Addresses
And you are trying to insert a duplicate via the _Order.OrderNumber
Do a
select * from AC_Shipping_Addresses where pk_OrderID = 165863;
or select count(*) ....
Pretty sure you will get a row returned.
What it is telling you is you are already using pk_OrderID = 165863 and cannot have another row with that value.
if you want to not insert if there is a row
insert into table (pk, value)
select 11 as pk, 'val' as value
where not exists (select 1 from table where pk = 11)

In python the with
keyword is used when working with unmanaged resources (like file streams). It is similar to the using
statement in VB.NET and C#. It allows you to ensure that a resource is "cleaned up" when the code that uses it finishes running, even if exceptions are thrown. It provides 'syntactic sugar' for try/finally
blocks.
From Python Docs:
The
with
statement clarifies code that previously would usetry...finally
blocks to ensure that clean-up code is executed. In this section, I’ll discuss the statement as it will commonly be used. In the next section, I’ll examine the implementation details and show how to write objects for use with this statement.The
with
statement is a control-flow structure whose basic structure is:with expression [as variable]: with-block
The expression is evaluated, and it should result in an object that supports the context management protocol (that is, has
__enter__()
and__exit__()
methods).
Update fixed VB callout per Scott Wisniewski's comment. I was indeed confusing with

The two queries express the same question. Apparently the query optimizer chooses two different execution plans. My guess would be that the distinct
approach is executed like:
business_key
values to a temporary tableThe group by
could be executed like:
business key
in a hashtableThe first method optimizes for memory usage: it would still perform reasonably well when part of the temporary table has to be swapped out. The second method optimizes for speed, but potentially requires a large amount of memory if there are a lot of different keys.
Since you either have enough memory or few different keys, the second method outperforms the first. It's not unusual to see performance differences of 10x or even 100x between two execution plans.
You can try
echo implode(', ', (array)$ret);
If you're into libraries, why not MyLibrary and getStyle.
The jQuery css method is misnamed, CSS is just one way of setting styles and doesn't necessarily represent the actual values of an element's style properties.
Put the div in another div and set the parent div's style to position:relative;
Then on the child div set the following CSS properties: position:absolute; bottom:0;
Similar situation. It was working. Then, I started to include pytables. At first view, no reason to errors. I decided to use another function, that has a domain constraint (elipse) and received the following error:
TypeError: 'numpy.float64' object cannot be interpreted as an integer
or
TypeError: 'numpy.float64' object is not iterable
The crazy thing: the previous function I was using, no code changed, started to return the same error. My intermediary function, already used was:
def MinMax(x, mini=0, maxi=1)
return max(min(x,mini), maxi)
The solution was avoid numpy
or math
:
def MinMax(x, mini=0, maxi=1)
x = [x_aux if x_aux > mini else mini for x_aux in x]
x = [x_aux if x_aux < maxi else maxi for x_aux in x]
return max(min(x,mini), maxi)
Then, everything calm again. It was like one library possessed max
and min
!
I have also tried some things using the asynchronous methods in python, how ever I have had much better luck using twisted for asynchronous programming. It has fewer problems and is well documented. Here is a link of something simmilar to what you are trying in twisted.

This will delete all content from current line to end of the file. This is very useful when you're dealing with test vector generation or stripping.
This is most definitely a programming problem. The problem is that it cannot be programmed, per se. When P is actually zero then the concept of percentage change has no meaning. Zero to anything cannot be expressed as a rate as it is outside the definition boundary of rate. Going from 'not being' into 'being' is not a change of being, it is instead creation of being.
You can do something like this to extract the value you want from JavaScript instead of an attribute:
<a href='#' class='click'>
<span style='display:none;'>value for JavaScript</span>some text
</a>
I would suggest you to use a simple and easy plugin called as Quokka which is very popular these days and helps you debug your code on the go. Quokka.js. One biggest advantage in using this plugin is that you save a lot of time to go on web browser and evaluate your code, with help of this you can see everything happening in VS code, which saves a lot of time.
I think you are putting one too many curly brackets. Try this
@if($user->status=='waiting')
<td><a href="#" class="viewPopLink btn btn-default1" role="button" data-id="{!! $user->travel_id !!}" data-toggle="modal" data-target="#myModal">Approve/Reject</a> </td>
@else
<td>{!! $user->status !!}</td>
@endif
IF EXISTS (SELECT 1 FROM Table WHERE FieldValue='')
BEGIN
SELECT TableID FROM Table WHERE FieldValue=''
END
ELSE
BEGIN
INSERT INTO TABLE(FieldValue) VALUES('')
SELECT SCOPE_IDENTITY() AS TableID
END
See here for more information on IF ELSE
Note: written without a SQL Server install handy to double check this but I think it is correct
Also, I've changed the EXISTS bit to do SELECT 1 rather than SELECT * as you don't care what is returned within an EXISTS, as long as something is I've also changed the SCOPE_IDENTITY() bit to return just the identity assuming that TableID is the identity column
I'm a bit late in answering this question, but had the same problem recently (people cut and paste all sorts of stuff into a string and we don't always know what it is). The following is a simple character whitelist approach:
SELECT est.clients_ref
,TRANSLATE (
est.clients_ref
, 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890#$%^&*()_+-={}|[]:";<>?,./'
|| REPLACE (
TRANSLATE (
est.clients_ref
,'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890#$%^&*()_+-={}|[]:";<>?,./'
,'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~'
)
,'~'
)
,'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890#$%^&*()_+-={}|[]:";<>?,./'
)

Change return false;
to return true;
in longClickListener
You long click the button, if it returns true then it does the work. If it returns false then it does it's work and also calls the short click and then the onClick also works.
Use the FileSystemObject
object, namely, its CreateFolder
and CopyFile
methods. Basically, this is what your script will look like:
Dim oFSO
Set oFSO = CreateObject("Scripting.FileSystemObject")
' Create a new folder
oFSO.CreateFolder "C:\MyFolder"
' Copy a file into the new folder
' Note that the destination folder path must end with a path separator (\)
oFSO.CopyFile "\\server\folder\file.ext", "C:\MyFolder\"
You may also want to add additional logic, like checking whether the folder you want to create already exists (because CreateFolder
raises an error in this case) or specifying whether or not to overwrite the file being copied. So, you can end up with this:
Const strFolder = "C:\MyFolder\", strFile = "\\server\folder\file.ext"
Const Overwrite = True
Dim oFSO
Set oFSO = CreateObject("Scripting.FileSystemObject")
If Not oFSO.FolderExists(strFolder) Then
oFSO.CreateFolder strFolder
End If
oFSO.CopyFile strFile, strFolder, Overwrite
use ng-intl-tel-input to validate mobile numbers for all countries. you can set default country also. on npm: https://www.npmjs.com/package/ng-intl-tel-input
more details: https://techpituwa.wordpress.com/2017/03/29/angular-js-phone-number-validation-with-ng-intl-tel-input/
Since I actually really needed this solution, and the typical baseline solution (focus the input - then set the value equal to itself) doesn't work cross-browser, I spent some time tweaking and editing everything to get it working. Building upon @kd7's code here's what I've come up with.
Enjoy! Works in IE6+, Firefox, Chrome, Safari, Opera
Cross-browser caret positioning technique (example: moving the cursor to the END)
// ** USEAGE ** (returns a boolean true/false if it worked or not)
// Parameters ( Id_of_element, caretPosition_you_want)
setCaretPosition('IDHERE', 10); // example
The meat and potatoes is basically @kd7's setCaretPosition, with the biggest tweak being if (el.selectionStart || el.selectionStart === 0)
, in firefox the selectionStart is starting at 0, which in boolean of course is turning to False, so it was breaking there.
In chrome the biggest issue was that just giving it .focus()
wasn't enough (it kept selecting ALL of the text!) Hence, we set the value of itself, to itself el.value = el.value;
before calling our function, and now it has a grasp & position with the input to use selectionStart.
function setCaretPosition(elemId, caretPos) {
var el = document.getElementById(elemId);
el.value = el.value;
// ^ this is used to not only get "focus", but
// to make sure we don't have it everything -selected-
// (it causes an issue in chrome, and having it doesn't hurt any other browser)
if (el !== null) {
if (el.createTextRange) {
var range = el.createTextRange();
range.move('character', caretPos);
range.select();
return true;
}
else {
// (el.selectionStart === 0 added for Firefox bug)
if (el.selectionStart || el.selectionStart === 0) {
el.focus();
el.setSelectionRange(caretPos, caretPos);
return true;
}
else { // fail city, fortunately this never happens (as far as I've tested) :)
el.focus();
return false;
}
}
}
}
Your installation is missing some php modules, there should be a list of required modules in the phpmyadmin readme. If you recently enabled the modules, try restarting the apache service / daemon.
Edit: As it seems, there is no single "enable these modules" in the docs, so enable either mysql
or mysqli
in your php.ini (you might need to install it first).
The two messages are not important if you do not intend to upload or download compressed file within phpMyAdmin. If you do, enable the zlib
and / or bz2
modules.
If your text contains only one individual:
import re
# creation
with open('pers.txt','wb') as g:
g.write('Dan \n Warrior \n 500 \r\n 1 \r 0 ')
with open('pers.txt','rb') as h:
print 'exact content of pers.txt before treatment:\n',repr(h.read())
with open('pers.txt','rU') as h:
print '\nrU-display of pers.txt before treatment:\n',h.read()
# treatment
def roplo(file_name,what):
patR = re.compile('^([^\r\n]+[\r\n]+)[^\r\n]+')
with open(file_name,'rb+') as f:
ch = f.read()
f.seek(0)
f.write(patR.sub('\\1'+what,ch))
roplo('pers.txt','Mage')

with open('pers.txt','rb') as h:
print '\nexact content of pers.txt after treatment:\n',repr(h.read())
with open('pers.txt','rU') as h:
print '\nrU-display of pers.txt after treatment:\n',h.read()
If your text contains several individuals:
import re

with open('pers.txt','wb') as g:
g.write('Dan \n Warrior \n 500 \r\n 1 \r 0 \n Jim \n dragonfly\r300\r2\n10\r\nSomo\ncosmonaut\n490\r\n3\r65')

If the “job“ of an individual was of a constant length in the texte, you could change only the portion of texte corresponding to the “job“ the desired individual: that’s the same idea as senderle’s one.
But according to me, better would be to put the characteristics of individuals in a dictionnary recorded in file with cPickle:
from cPickle import dump, load
with open('cards','wb') as f:
dump({'Dan':['Warrior',500,1,0],'Jim':['dragonfly',300,2,10],'Somo':['cosmonaut',490,3,65]},f)
with open('cards','rb') as g:
id_cards = load(g)
print 'id_cards before change==',id_cards
id_cards['Jim'][0] = 'Wizard'
with open('cards','w') as h:
dump(id_cards,h)
with open('cards') as e:
id_cards = load(e)
print '\nid_cards after change==',id_cards
As other answers point out, there are many and good reasons why this class
was made generic. However there are plenty of times that you don't have any way of knowing the generic type to use with Class<T>
. In these cases, you can simply ignore the yellow eclipse warnings or you can use Class<?>
... That's how I do it ;)
Most of answers here are rather complex, but isn't logic behind this quite simple?
const getArraysDifference = (longerArray, array2) => {
const difference = [];
longerArray.forEach(el1 => { /*1*/
el1IsPresentInArr2 = array2.some(el2 => el2.value === el1.value); /*2*/
if (!el1IsPresentInArr2) { /*3*/
difference.push(el1); /*4*/
}
});
return difference;
}
O(n^2) complexity.
I had the same problem.
I wanted to view my diagram, which I created the same day at work, at home. But I couldn't because of this message.
I found out that the owner of the database was the user of my computer -as expected. but since the computer is in the company's domain, and I am not connected to the company's network, the database couldn't resolve the owner.
So what I did is change the owner to a local user and it worked!!
Hope this helps someone.
You change the user by right-click on the database, properties, files, owner
It happens that /etc/hosts
file doesn't support wild card entries.
You'll have to use other services like dnsmasq. To enable it in dnsmasq, just edit dnsmasq.conf
and add the following line:
address=/example.com/127.0.0.1
I don't see any margin
or margin-left
declarations for #footer-wrap li
.
This ought to do the trick:
#footer-wrap ul,
#footer-wrap li {
margin-left: 0;
list-style-type: none;
}
To use unsafe code blocks, the project has to be compiled with the /unsafe switch on.
Open the properties for the project, go to the Build
tab and check the Allow unsafe code
checkbox.
You should check that what you are passing to foreach
is an array by using the is_array function
If you are not sure it's going to be an array you can always check using the following PHP example code:
if (is_array($variable)) {
foreach ($variable as $item) {
//do something
}
}
columnDefinition will override the sql DDL generated by hibernate for this particular column, it is non portable and depends on what database you are using. You can use it to specify nullable, length, precision, scale... ect.
Simple way in Java
public void resize(String inputImagePath,
String outputImagePath, int scaledWidth, int scaledHeight)
throws IOException {
// reads input image
File inputFile = new File(inputImagePath);
BufferedImage inputImage = ImageIO.read(inputFile);
// creates output image
BufferedImage outputImage = new BufferedImage(scaledWidth,
scaledHeight, inputImage.getType());
// scales the input image to the output image
Graphics2D g2d = outputImage.createGraphics();
g2d.drawImage(inputImage, 0, 0, scaledWidth, scaledHeight, null);
g2d.dispose();
// extracts extension of output file
String formatName = outputImagePath.substring(outputImagePath
.lastIndexOf(".") + 1);
// writes to output file
ImageIO.write(outputImage, formatName, new File(outputImagePath));
}
As an important issue, when you want to utilize shell to delete .svn folders You need -depth argument to prevent find command entering the directory that was just deleted and showing error messages like e.g.
"find: ./.svn: No such file or directory"
As a result, You can use find command like below:
cd [dir_to_delete_svn_folders]
find . -depth -name .svn -exec rm -fr {} \;
You should be able to just run select * from information_schema.tables
to get a listing of every table being managed by Postgres for a particular database.
You can also add a where table_schema = 'information_schema'
to see just the tables in the information schema.

First of all open visual studio code settings in json and add following arguments after "[python]":{}
"python.linting.pylintArgs": ["--rep[![enter image description here][1]][1]orts", "12", "--disable", "I0011"], "python.linting.flake8Args": ["--ignore=E24,W504", "--verbose"] "python.linting.pydocstyleArgs": ["--ignore=D400", "--ignore=D4"]
This has solved my issue with pylint
This usually happens when the repo contains some items that are not there locally. So in order to push our changes, in this case we need to integrate the remote changes and then push.
So create a pull from remote
git pull origin master
Then push changes to that remote
git push origin master
You must have either disabled
, froze
or uninstalled
FaceProvider in settings>applications>all
This will only happen if it's frozen
, either uninstall
it, or enable
it.
This usually works as well :)
navigateUpTo(new Intent(getBaseContext(), MainActivity.class));
It doesn't - the C# compiler does :)
So this code:
string x = "hello";
string y = "there";
string z = "chaps";
string all = x + y + z;
actually gets compiled as:
string x = "hello";
string y = "there";
string z = "chaps";
string all = string.Concat(x, y, z);
(Gah - intervening edit removed other bits accidentally.)
The benefit of the C# compiler noticing that there are multiple string concatenations here is that you don't end up creating an intermediate string of x + y
which then needs to be copied again as part of the concatenation of (x + y)
and z
. Instead, we get it all done in one go.
EDIT: Note that the compiler can't do anything if you concatenate in a loop. For example, this code:
string x = "";
foreach (string y in strings)
{
x += y;
}
just ends up as equivalent to:
string x = "";
foreach (string y in strings)
{
x = string.Concat(x, y);
}
... so this does generate a lot of garbage, and it's why you should use a StringBuilder
for such cases. I have an article going into more details about the two which will hopefully answer further questions.

What version of SQL Server are you using? In SQL Server 2008 you can use Table Parameters and Table Types.
An alternative approach is to return a table variable from a user defined function but I am not a big fan of this method.
You can find an example here
Wow, you have a huge misunderstanding how asp.net works.
This line of code
System.Diagnostics.Process.Start("help/AdminTutorial.html");
Will not redirect a admin user to a new site, but start a new process on the server (usually a browser, IE) and load the site. That is for sure not what you want.
A very easy solution would be to change the href attribute of the link in you page_load method.
Your aspx code:
<a href="#" runat="server" id="myLink">Tutorial</a>
Your codebehind / cs code of page_load:
...
if (userinfo.user == "Admin")
{
myLink.Attributes["href"] = "help/AdminTutorial.html";
}
else
{
myLink.Attributes["href"] = "help/otherSite.html";
}
...
Don't forget to check the Admin rights again on "AdminTutorial.html" to "prevent" hacking.
Don't forget to have the standard css declarations above the media query or the query won't work either.

To find all tables containing a particular foreign key such as employee_id
SELECT DISTINCT TABLE_NAME
FROM INFORMATION_SCHEMA.COLUMNS
WHERE COLUMN_NAME IN ('employee_id')
AND TABLE_SCHEMA='table_name';
you can format date just making this type of the code.In javascript.
// for eg.
var inputdate=document.getElementById("getdate").value);
var datecomp= inputdate.split('.');
Var Date= new Date(datecomp[2], datecomp[1]-1, datecomp[0]);
//new date( Year,Month,Date)
This is in answer to your question...
I'd also like to know how to make it open up in Sublime Text 2 instead
For Windows:
git config --global core.editor "'C:/Program Files/Sublime Text 2/sublime_text.exe'"
Check that the path for sublime_text.exe
is correct and adjust if needed.
For Mac/Linux:
git config --global core.editor "subl -n -w"
If you get an error message such as:
error: There was a problem with the editor 'subl -n -w'.
Create the alias for subl
sudo ln -s /Applications/Sublime\ Text.app/Contents/SharedSupport/bin/subl /usr/local/bin/subl
Again check that the path matches for your machine.
For Sublime Text simply save cmd S
and close the window cmd W
to return to git.
Besides the mentioned fact that JSX tags are not standard javascript, the reason I use .jsx extension is because with it Emmet still works in the editor - you know, that useful plugin that expands html code, for example ul>li into
<ul>
<li></li>
</ul>

I was also stuck on the same kind of problem and I followed the simple steps below.
Just get the exact url of the file to which you want to copy, for example:
http://www.test.com/test.txt (file to copy)
Then pass the exact absolute folder path with filename where you do want to write that file.
If you are on a Windows machine then
d:/xampp/htdocs/upload/test.txt
If you are on a Linux machine then
/var/www/html/upload/test.txt
You can get the document root with the PHP function $_SERVER['DOCUMENT_ROOT']
.
Use
echo "your sql script;" | mysql -u -p -h db_name
after you have pulled and updated your workspace do a thg and right click on the change set you want to get rid of and then click modify history -> strip, it will remove the change set and you will point to default tip.
There are several methods, two of which are as follows. Provide a custom installer or a setup project.
Here is how to create a custom installer
[RunInstaller(true)]
public class MyInstaller : Installer
{
public HelloInstaller()
: base()
{
}
public override void Commit(IDictionary mySavedState)
{
base.Commit(mySavedState);
System.IO.File.CreateText("Commit.txt");
}
public override void Install(IDictionary stateSaver)
{
base.Install(stateSaver);
System.IO.File.CreateText("Install.txt");
}
public override void Uninstall(IDictionary savedState)
{
base.Uninstall(savedState);
File.Delete("Commit.txt");
File.Delete("Install.txt");
}
public override void Rollback(IDictionary savedState)
{
base.Rollback(savedState);
File.Delete("Install.txt");
}
}
To add a setup project
Menu file -> New -> Project --> Other Projects Types --> Setup and Deployment
Set properties of the project, using the properties window
The article How to create a Setup package by using Visual Studio .NET provides the details.
WinSCP has the command line functionality:

FileZilla does have a command line but it is limited to only opening the GUI with a pre-defined server that is in the Site Manager.
Use this:

If you start out with:
let array = [
{name: "malcom", dogType: "four-legged"},
{name: "peabody", dogType: "three-legged"},
{name: "pablo", dogType: "two-legged"}
];
And you want a set of, say, names, you would do:
let namesSet = new Set(array.map(item => item.name));
The below code works for me -:
jQuery('[id^=select_] > option').each(function(){
if (this.text.toLowerCase()=='text'){

}
});
jQuery('[id^=select_]') - This allows you to select drop down where ID of the drop down starts from select_

getClientRects
return the client rects like this and if you want to get the lines, use the follow function like this
function getRowRects(element) {

clientRect, top, rectsLen, rect, i;
for(i=0; i<len; i++) {

rect = rects[rectsLen];
if (rect.top == top) {
has = true;
break;
}
}
if(has) {
rect.right = rect.right > clientRect.right ? rect.right : clientRect.right;
rect.width = rect.right - rect.left;
}

>>> from itertools import compress
>>> list(compress(xrange(len(t)), t))
[4, 5, 7]
>>> t = t*1000
>>> %timeit [i for i, x in enumerate(t) if x]
100 loops, best of 3: 2.55 ms per loop
>>> %timeit list(compress(xrange(len(t)), t))
1000 loops, best of 3: 696 µs per loop
Step 1 extract the contents of dex2jar.*.*.zip file Step 2 copy your .dex file to the extracted directory Step 3 execute dex2jar.bat <.dex filename> on windows, or ./dex2jar.sh <.dex filename> on linux
As a general advice, I would recommend not stealing the focus from the address bar. (Jeff already talked about that.)
Web page can take some time to load, which means that your focus change can occur some long time after the user typed the pae URL. Then he could have changed his mind and be back to url typing while you will be loading your page and stealing the focus to put it in your textbox.
That's the one and only reason that made me remove Google as my start page.
Of course, if you control the network (local network) or if the focus change is to solve an important usability issue, forget all I just said :)
C# 8 now (since 2019) supports Ranges which allows you to achieve Slice much easier (similar to JS syntax):
var array = new int[] { 1, 2, 3, 4, 5 };
var slice1 = array[2..^3]; // array[new Range(2, new Index(3, fromEnd: true))]
var slice2 = array[..^3]; // array[Range.EndAt(new Index(3, fromEnd: true))]
var slice3 = array[2..]; // array[Range.StartAt(2)]
var slice4 = array[..]; // array[Range.All]
You can use ranges instead of the well known LINQ functions: Skip(), Take(), Count().
You can use "system.properties.os", for example:
public class GetOs {
public static void main (String[] args) {
String s =
"name: " + System.getProperty ("os.name");
s += ", version: " + System.getProperty ("os.version");
s += ", arch: " + System.getProperty ("os.arch");
System.out.println ("OS=" + s);
}
}
// EXAMPLE OUTPUT: OS=name: Windows 7, version: 6.1, arch: amd64
Here are more details:
Solution with LOCALE_ID is great if you want to set the language for your app once. But it doesn’t work, if you want to change the language during runtime. For this case you can implement custom date pipe.
import { DatePipe } from '@angular/common';
import { Pipe, PipeTransform } from '@angular/core';
import { TranslateService } from '@ngx-translate/core';
@Pipe({
name: 'localizedDate',
pure: false
})
export class LocalizedDatePipe implements PipeTransform {
constructor(private translateService: TranslateService) {
}
transform(value: any, pattern: string = 'mediumDate'): any {
const datePipe: DatePipe = new DatePipe(this.translateService.currentLang);
return datePipe.transform(value, pattern);
}
}
Now if you change the app display language using TranslateService (see ngx-translate)
this.translateService.use('en');
the formats within your app should automatically being updated.
Example of use:
<p>{{ 'note.created-at' | translate:{date: note.createdAt | localizedDate} }}</p>
<p>{{ 'note.updated-at' | translate:{date: note.updatedAt | localizedDate:'fullDate'} }}</p>
or check my simple "Notes" project here.
You can read it by chunks (byte buffer[] = new byte[2048]
) and write the chunks to a ByteArrayOutputStream. From the ByteArrayOutputStream you can retrieve the contents as a byte[], without needing to determine its size beforehand.
I had a similar issue and solved with the following steps after connecting the device via USB:
Now we can see attached devices.

Just copy war file to standalone/deployments/ folder, it should deploy it automatically. It'll also create your_app_name.deployed file, when your application is deployed. Also be sure that you start server with bin/standalone.sh script.
A interesting writeup on the logical differences: SQL Server: JOIN vs IN vs EXISTS - the logical difference
I am pretty sure that assuming that the relations and indexes are maintained a Join will perform better overall (more effort goes into working with that operation then others). If you think about it conceptually then its the difference between 2 queries and 1 query.
You need to hook it up to the Query Analyzer and try it and see the difference. Also look at the Query Execution Plan and try to minimize steps.
Send XML requests with the raw
data type, then set the Content-Type to text/xml
.
After creating a request, use the dropdown to change the request type to POST.
Open the Body tab and check the data type for raw.
Open the Content-Type selection box that appears to the right and select either XML (application/xml) or XML (text/xml)
Enter your raw XML data into the input field below
Click Send to submit your XML Request to the specified server.
**Different way to Find Element:**
IEDriver.findElement(By.id("id"));
IEDriver.findElement(By.linkText("linkText"));
IEDriver.findElement(By.xpath("xpath"));
IEDriver.findElement(By.xpath(".//*[@id='id']"));
IEDriver.findElement(By.xpath("//button[contains(.,'button name')]"));
IEDriver.findElement(By.xpath("//a[contains(.,'text name')]"));
IEDriver.findElement(By.xpath("//label[contains(.,'label name')]"));
IEDriver.findElement(By.xpath("//*[contains(text(), 'your text')]");
Check Case Sensitive:
IEDriver.findElement(By.xpath("//*[contains(lower-case(text()),'your text')]");
For exact match:
IEDriver.findElement(By.xpath("//button[text()='your text']");
**Find NG-Element:**
Xpath == //td[contains(@ng-show,'childsegment.AddLocation')]
CssSelector == .sprite.icon-cancel
A multiple select is really just a select with a multiple
attribute. With that in mind, it should be as easy as...
Form::select('sports[]', $sports, null, array('multiple'))
The first parameter is just the name, but post-fixing it with the []
will return it as an array when you use Input::get('sports')
.
The second parameter is an array of selectable options.
The third parameter is an array of options you want pre-selected.
The fourth parameter is actually setting this up as a multiple select dropdown by adding the multiple
property to the actual select element..
Selected date at the example is interesting. Example code block is:
Calendar c1 = GregorianCalendar.getInstance();
c1.set(2000, 1, 30); //January 30th 2000
Date sDate = c1.getTime();
System.out.println(sDate);
and output Wed Mar 01 19:32:21 JST 2000
.
When I first read the example i think that output is wrong but it is true:)
Calendar.Month
is starting from 0 so 1 means February.What I did to make one of my projects to check out properly is by
1) Import your project from svn
file-->import-->SVN-Checkout Projects From SVN
2) Find your Project and then in the "Check Out As" dialogue make sure you have the radio button selected "Check out as a project configured using the New Project Wizard"
3) Go through regular steps.
The wizard pulls the project properly and then setups your eclipse....
without using the wizard I find that all hell breaks loose.....
Hope this helps...
You also can try out this
final WebView webView = new WebView(this);
webView.loadDataWithBaseURL(null, content, "text/html", "UTF-8", null);
You don't mention what language you want to track these in, but I found two for javascript:
Layers are conceptual entities, and are used to separate the functionality of software system from a logical point of view; when you implement the system you organize these layers using different methods; in this condition we refer to them not as layers but as tiers.
Both values can be easily distinguished by using the strict comparison operator:
Working example at:
http://www.thesstech.com/tryme?filename=nullandundefined
Sample Code:
function compare(){
var a = null; //variable assigned null value
var b; // undefined
if (a === b){
document.write("a and b have same datatype.");
}
else{
document.write("a and b have different datatype.");
}
}
you might use
a.view(1,5)
Out:
1 2 3 4 5
[torch.FloatTensor of size 1x5]

First understand that you have three languages working together.
PHP: Is only run by the server and responds to requests like clicking on a link (GET) or submitting a form (POST). HTML & Javascript: Is only run in someone's browser (excluding NodeJS) I'm assuming your file looks something like:
<?php
function the_function() {
echo 'I just ran a php function';
}
if (isset($_GET['hello'])) {
the_function();
}
?>
<html>
<a href='the_script.php?hello=true'>Run PHP Function</a>
</html>
Because PHP only responds to requests (GET, POST, PUT, PATCH, and DELETE via $_REQUEST) this is how you have to run a php function even though their in the same file. This gives you a level of security, "Should I run this script for this user or not?".
If you don't want to refresh the page you can make a request to PHP without refreshing via a method called Asynchronous Javascript and XML (AJAX).
If you're storing the object as type object
, you need to use reflection. This is true of any object type, anonymous or otherwise. On an object o, you can get its type:
Type t = o.GetType();
Then from that you look up a property:
PropertyInfo p = t.GetProperty("Foo");
Then from that you can get a value:
object v = p.GetValue(o, null);
This answer is long overdue for an update for C# 4:
dynamic d = o;
object v = d.Foo;
And now another alternative in C# 6:
object v = o?.GetType().GetProperty("Foo")?.GetValue(o, null);
Note that by using ?.
we cause the resulting v
to be null
in three different situations!
o
is null
, so there is no object at allo
is non-null
but doesn't have a property Foo
o
has a property Foo
but its real value happens to be null
.So this is not equivalent to the earlier examples, but may make sense if you want to treat all three cases the same.
I had the same error message and after lots of trial and error found out that it was caused by an advanced filter which was set on the ListObject. After clearing the advanced filter .listrows.add worked fine again. To clear the filter I use this - no idea how one could clear the filter only for the specific listobject instead of the complete worksheet.
Worksheets("mysheet").ShowAllData
If your path contains space then try using %~s1
. This will remove the space and appends ~1
to your path and more importantly it refers to the absolute path of your file. Try using it.
You need to close the connection before you can use the output parameters. Something like this
con.Close();
MessageBox.Show(cmd.Parameters["@code"].Value.ToString());
For read-only controls they are the same. For 2 way databinding, using a datasource in which you want to update, insert, etc with declarative databinding, you'll need to use Bind
.
Imagine for example a GridView with a ItemTemplate
and EditItemTemplate
. If you use Bind
or Eval
in the ItemTemplate
, there will be no difference. If you use Eval
in the EditItemTemplate
, the value will not be able to be passed to the Update
method of the DataSource
that the grid is bound to.
UPDATE: I've come up with this example:
<%@ Page Language="C#" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<EditItemTemplate>

</asp:GridView>
</form>
<asp:ObjectDataSource
ID="mySource"
runat="server"
SelectMethod="Select"
UpdateMethod="Update"
TypeName="MyCompany.CustomDataSource" />
</body>
</html>
And here's the definition of a custom class that serves as object data source:
public class CustomDataSource
{
public class Model
{
public string Name { get; set; }
}
public IEnumerable<Model> Select()
{
return new[]
{
new Model { Name = "some value" }
};
}
public void Update(string Name)
{
// This method will be called if you used Bind for the TextBox
// and you will be able to get the new name and update the
// data source accordingly
}
public void Update()
{
// This method will be called if you used Eval for the TextBox
// and you will not be able to get the new name that the user
// entered
}
}
For me the issue was different: Angular-cli was not installed (I installed a new Node version using NVM and simply forgot to reinstall angular cli)
You can check running "ng version".
If you don't have it just run "npm install -g @angular/cli"

This is my running one https://github.com/surya4/jquery-json.
The answers mentioned here is quite elegant https://stackoverflow.com/a/6095776/1869562 but upon testing, I realize it only returns the last name. What if you want to return the entire record itself ? Do this (For Mysql)
SELECT *
FROM `beneficiary`
WHERE `lastname`
IN (
SELECT `lastname`
FROM `beneficiary`
GROUP BY `lastname`
HAVING COUNT( `lastname` ) >1
)
I don't think there's a builtin function in angular for doing this, but you can do this by creating a separate scope property containing all the header names, and you can fill this property automatically like this:
var data = {
foo: 'a',
bar: 'b'
};
$scope.objectHeaders = [];
for ( property in data ) {
$scope.objectHeaders.push(property);
}
// Output: [ 'foo', 'bar' ]
I had this same error while trying to include a PHP file in my Wordpress theme. I was able to get around it by referencing the file name using dirname(__FILE__)
. I couldn't use relative paths since my file was going to be included in different places throughout the theme, so something like require_once '../path-to/my-file'
wouldn't work.
Replacing require_once get_template_directory_uri() . '/path-to/my-file'
with require_once dirname( __FILE__ ) . '/path-to/my-file'
did the trick.
Write a new class that holds all the values that you need and use the new class's object as the value in your HashMap
HashMap<String, MyObject>
class MyObject {
public String value1;
public int value2;
public List<String> value3;
}
I think this is what you want:
document.getElementById('tag-id').innerHTML = '<ol><li>html data</li></ol>';
Keep in mind that innerHTML is not accessible for all types of tags when using IE. (table elements for example)
Usually what you choose will depend on which methods you need access to. In general - IEnumerable<>
(MSDN: http://msdn.microsoft.com/en-us/library/system.collections.ienumerable.aspx) for a list of objects that only needs to be iterated through, ICollection<>
(MSDN: http://msdn.microsoft.com/en-us/library/92t2ye13.aspx) for a list of objects that needs to be iterated through and modified, List<>
for a list of objects that needs to be iterated through, modified, sorted, etc (See here for a full list: http://msdn.microsoft.com/en-us/library/6sh2ey19.aspx).
From a more specific standpoint, lazy loading comes in to play with choosing the type. By default, navigation properties in Entity Framework come with change tracking and are proxies. In order for the dynamic proxy to be created as a navigation property, the virtual type must implement ICollection
.
A navigation property that represents the "many" end of a relationship must return a type that implements ICollection, where T is the type of the object at the other end of the relationship. -Requirements for Creating POCO ProxiesMSDN
function htmlDecode(t){
if (t) return $('<div />').html(t).text();
}

You need to use the Scatter chart type instead of Line. That will allow you to define separate X values for each series.
Use the left
function:
QString yourString = "This is a string";
QString leftSide = yourString.left(5);
qDebug() << leftSide; // output "This "
Also have a look at mid()
if you want more control.
Delete your .git folder, and reinitialize the git with git init, in my case that's work , because git add command staging the folder and the files in .git folder, if you close CLI after the commit , there will be double folder in staging area that make git system throw this issue.
To understand the nouns, let's focus on the verbs first.
declare - to announce officially; proclaim
define - to show or describe (someone or something) clearly and completely
So, when you declare something, you just tell what it is.
// declaration
int sum(int, int);
This line declares a C function called sum
that takes two arguments of type int
and returns an int
. However, you can't use it yet.
When you provide how it actually works, that's the definition of it.
// definition
int sum(int x, int y)
{
return x + y;
}
=
can be used when the subquery returns only 1 value.
When subquery returns more than 1 value, you will have to use IN
:
select *
from table
where id IN (multiple row query);
For example:
SELECT *
FROM Students
WHERE Marks = (SELECT MAX(Marks) FROM Students) --Subquery returns only 1 value
SELECT *
FROM Students
WHERE Marks IN
(SELECT Marks
FROM Students
ORDER BY Marks DESC
LIMIT 10) --Subquery returns 10 values
You can just add a new submodule and remove the old submodule using standard commands. (should prevent any accidental errors inside of .git)
Example setup:
mkdir foo; cd foo; git init;
echo "readme" > README.md; git add README.md; git commit -m "First"
## add submodule
git submodule add git://github.com/jquery/jquery.git
git commit -m "Added jquery"
## </setup example>
Examle move 'jquery' to 'vendor/jquery/jquery' :
oldPath="jquery"
newPath="vendor/jquery/jquery"
orginUrl=`git config --local --get submodule.${oldPath}.url`
## add new submodule
mkdir -p `dirname "${newPath}"`
git submodule add -- "${orginUrl}" "${newPath}"
## remove old submodule
git config -f .git/config --remove-section "submodule.${oldPath}"
git config -f .gitmodules --remove-section "submodule.${oldPath}"
git rm --cached "${oldPath}"
rm -rf "${oldPath}" ## remove old src
rm -rf ".git/modules/${oldPath}" ## cleanup gitdir (housekeeping)
## commit
git add .gitmodules
git commit -m "Renamed ${oldPath} to ${newPath}"
Bonus method for large submodules:
If the submodule is large and you prefer not to wait for the clone, you can create the new submodule using the old as origin, and then switch the origin.
Example (use same example setup)
oldPath="jquery"
newPath="vendor/jquery/jquery"
baseDir=`pwd`
orginUrl=`git config --local --get submodule.${oldPath}.url`
# add new submodule using old submodule as origin
mkdir -p `dirname "${newPath}"`
git submodule add -- "file://${baseDir}/${oldPath}" "${newPath}"
## change origin back to original
git config -f .gitmodules submodule."${newPath}".url "${orginUrl}"
git submodule sync -- "${newPath}"
## remove old submodule
...
You need to give required = false
for name
and password
request parameters as well. That's because, when you provide just the logout
parameter, it actually expects for name
and password
as well as they are still mandatory.
It worked when you just gave name
and password
because logout
wasn't a mandatory parameter thanks to required = false
already given for logout
.
Angular Concepts
imports
makes the exported declarations of other modules available in the current moduledeclarations
are to make directives (including components and pipes) from the current module available to other directives in the current module. Selectors of directives, components or pipes are only matched against the HTML if they are declared or imported.providers
are to make services and values known to DI (dependency injection). They are added to the root scope and they are injected to other services or directives that have them as dependency.A special case for providers
are lazy loaded modules that get their own child injector. providers
of a lazy loaded module are only provided to this lazy loaded module by default (not the whole application as it is with other modules).
For more details about modules see also https://angular.io/docs/ts/latest/guide/ngmodule.html
exports
makes the components, directives, and pipes available in modules that add this module to imports
. exports
can also be used to re-export modules such as CommonModule and FormsModule, which is often done in shared modules.
entryComponents
registers components for offline compilation so that they can be used with ViewContainerRef.createComponent()
. Components used in router configurations are added implicitly.
TypeScript (ES2015) imports
import ... from 'foo/bar'
(which may resolve to an index.ts
) are for TypeScript imports. You need these whenever you use an identifier in a typescript file that is declared in another typescript file.
Angular's @NgModule()
imports
and TypeScript import
are entirely different concepts.
See also jDriven - TypeScript and ES6 import syntax
Most of them are actually plain ECMAScript 2015 (ES6) module syntax that TypeScript uses as well.
You need to apply
the event handler in the context of that element:
var elem = document.getElementById("linkid");
if (typeof elem.onclick == "function") {
elem.onclick.apply(elem);
}
Otherwise this
would reference the context the above code is executed in.

"This method uses the browser's innerHTML property." - jQuery API

From PEP 249, which is usually implemented by Python database APIs:
Cursor Objects should respond to the following methods and attributes:
[…]
.rowcount
This read-only attribute specifies the number of rows that the last .execute*() produced (for DQL statements like 'select') or affected (for DML statements like 'update' or 'insert').
But be careful—it goes on to say:
The attribute is -1 in case no
.execute*()
has been performed on the cursor or the rowcount of the last operation is cannot be determined by the interface. [7]Note:
Future versions of the DB API specification could redefine the latter case to have the object returnNone
instead of -1.
So if you've executed your statement, and it works, and you're certain your code will always be run against the same version of the same DBMS, this is a reasonable solution.
