The shorter ones are vectorized, meaning they can return a vector, like this:
((-2:2) >= 0) & ((-2:2) <= 0)
# [1] FALSE FALSE TRUE FALSE FALSE
The longer form evaluates left to right examining only the first element of each vector, so the above gives
((-2:2) >= 0) && ((-2:2) <= 0)
# [1] FALSE
As the help page says, this makes the longer form "appropriate for programming control-flow and [is] typically preferred in if clauses."
So you want to use the long forms only when you are certain the vectors are length one.
You should be absolutely certain your vectors are only length 1, such as in cases where they are functions that return only length 1 booleans. You want to use the short forms if the vectors are length possibly >1. So if you're not absolutely sure, you should either check first, or use the short form and then use all
and any
to reduce it to length one for use in control flow statements, like if
.
The functions all
and any
are often used on the result of a vectorized comparison to see if all or any of the comparisons are true, respectively. The results from these functions are sure to be length 1 so they are appropriate for use in if clauses, while the results from the vectorized comparison are not. (Though those results would be appropriate for use in ifelse
.
One final difference: the &&
and ||
only evaluate as many terms as they need to (which seems to be what is meant by short-circuiting). For example, here's a comparison using an undefined value a
; if it didn't short-circuit, as &
and |
don't, it would give an error.
a
# Error: object 'a' not found
TRUE || a
# [1] TRUE
FALSE && a
# [1] FALSE
TRUE | a
# Error: object 'a' not found
FALSE & a
# Error: object 'a' not found
Finally, see section 8.2.17 in The R Inferno, titled "and and andand".
Here's a compact way to do something different in all four cases:
if(empty($youtube)) {
if(empty($link)) {
# both empty
} else {
# only $youtube not empty
}
} else {
if(empty($link)) {
# only $link empty
} else {
# both not empty
}
}
If you want to use an expression instead, you can use ?:
instead:
echo empty($youtube) ? ( empty($link) ? 'both empty' : 'only $youtube not empty' )
: ( empty($link) ? 'only $link empty' : 'both not empty' );
Maybe you are looking for something like this. If you want to select the complete line when it contains both "foo" and "baz" at the same time, this RegEx will comply that:
.*(foo)+.*(baz)+|.*(baz)+.*(foo)+.*
You would want and
instead of &&
.
This problem will occurred due to some unnecessary changes made in my.cnf file.
Try to diff /etc/mysql/my.cnf
with one of working mysql servers my.cnf file.
I just replaced /etc/mysql/my.cnf
file with new my.cnf file and this works for me.
30x30 is points, which means 30px @1x, 60px @2x, not somewhere in-between. Also, it's not a great idea to embed the title of the tab into the image—you're going to have pretty poor accessibility and localization results like that.
When I use a non-default modules in my scripts I call the function below. Beside the module name you can provide a minimum version.
# See https://www.powershellgallery.com/ for module and version info

Here is code to do it directly with JavaScript. But, as previously mentioned, you'd be much better off with a JavaScript library. My favorite is jQuery.
In the case below, an ASPX page (that's servicing as a poor man's REST service) is being called to return a JavaScript JSON object.
var xmlHttp = null;
function GetCustomerInfo()
{
var CustomerNumber = document.getElementById( "TextBoxCustomerNumber" ).value;
var Url = "GetCustomerInfoAsJson.aspx?number=" + CustomerNumber;
xmlHttp = new XMLHttpRequest();
xmlHttp.onreadystatechange = ProcessRequest;
xmlHttp.open( "GET", Url, true );
xmlHttp.send( null );
}
function ProcessRequest()
{
if ( xmlHttp.readyState == 4 && xmlHttp.status == 200 )
{
if ( xmlHttp.responseText == "Not found" )
{
document.getElementById( "TextBoxCustomerName" ).value = "Not found";
document.getElementById( "TextBoxCustomerAddress" ).value = "";
}
else
{
var info = eval ( "(" + xmlHttp.responseText + ")" );
// No parsing necessary with JSON!
document.getElementById( "TextBoxCustomerName" ).value = info.jsonData[ 0 ].cmname;
document.getElementById( "TextBoxCustomerAddress" ).value = info.jsonData[ 0 ].cmaddr1;
}
}
}
When there is no records returned from Database for a particular condition and When I tried to access the rs.getString(1); I got this error "exhausted resultset".
Before the issue, my code was:
rs.next();
sNr= rs.getString(1);
After the fix:
while (rs.next()) {
sNr = rs.getString(1);
}
Just add position:absolute; top:0; right:0;
to the CSS for your button.
#button {
line-height: 12px;
width: 18px;
font-size: 8pt;
font-family: tahoma;
margin-top: 1px;
margin-right: 2px;
position:absolute;
top:0;
right:0;
}
for me deleting package-lock.json
fixed my problem,
turns out Heroku accepts only one package.json file :p
Remove display: block;
in the div #tfl
style property
<div id="tfl" style="display: block; width: 187px; height: 260px;
Inline style take priority then css file
EDIT 2017-04-29: As pointed to by some of the commenters, the JoinTable
example does not need the mappedBy
annotation attribute. In fact, recent versions of Hibernate refuse to start up by printing the following error:
org.hibernate.AnnotationException:
Associations marked as mappedBy must not define database mappings
like @JoinTable or @JoinColumn
Let's pretend that you have an entity named Project
and another entity named Task
and each project can have many tasks.
You can design the database schema for this scenario in two ways.
The first solution is to create a table named Project
and another table named Task
and add a foreign key column to the task table named project_id
:
Project Task
------- ----
id id
name name
project_id
This way, it will be possible to determine the project for each row in the task table. If you use this approach, in your entity classes you won't need a join table:
@Entity
public class Project {
@OneToMany(mappedBy = "project")
private Collection<Task> tasks;
}
@Entity
public class Task {
@ManyToOne
private Project project;
}
The other solution is to use a third table, e.g. Project_Tasks
, and store the relationship between projects and tasks in that table:
Project Task Project_Tasks
------- ---- -------------
id id project_id
name name task_id
The Project_Tasks
table is called a "Join Table". To implement this second solution in JPA you need to use the @JoinTable
annotation. For example, in order to implement a uni-directional one-to-many association, we can define our entities as such:
Project
entity:
@Entity
public class Project {
@Id
@GeneratedValue
private Long pid;
private String name;
@JoinTable
@OneToMany
private List<Task> tasks;
public Long getPid() {
return pid;
}
public void setPid(Long pid) {
this.pid = pid;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public List<Task> getTasks() {
return tasks;
}
public void setTasks(List<Task> tasks) {
this.tasks = tasks;
}
}
Task
entity:
@Entity
public class Task {
@Id
@GeneratedValue
private Long tid;
private String name;
public Long getTid() {
return tid;
}
public void setTid(Long tid) {
this.tid = tid;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
This will create the following database structure:
The @JoinTable
annotation also lets you customize various aspects of the join table. For example, had we annotated the tasks
property like this:
@JoinTable(
name = "MY_JT",
joinColumns = @JoinColumn(
name = "PROJ_ID",
referencedColumnName = "PID"
),
inverseJoinColumns = @JoinColumn(
name = "TASK_ID",
referencedColumnName = "TID"
)
)
@OneToMany
private List<Task> tasks;
The resulting database would have become:
Finally, if you want to create a schema for a many-to-many association, using a join table is the only available solution.
>>> for i in range(1, 11):
... print(i, end=' ')
... if i==len(range(1, 11)): print()
...
1 2 3 4 5 6 7 8 9 10
>>>
This is how to do it so that the printing does not run behind the prompt on the next line.
Using ==
to compare two enum values works, because there is only one object for each enum constant.
On a side note, there is actually no need to use ==
to write null-safe code, if you write your equals()
like this:
public useEnums(final SomeEnum a) {
if (SomeEnum.SOME_ENUM_VALUE.equals(a)) {
…
}
…
}
This is a best practice known as Compare Constants From The Left that you definitely should follow.
Autobahn has a good websocket client implementation for Python as well as some good examples. I tested the following with a Tornado WebSocket server and it worked.
from twisted.internet import reactor
from autobahn.websocket import WebSocketClientFactory, WebSocketClientProtocol, connectWS
class EchoClientProtocol(WebSocketClientProtocol):
def sendHello(self):
self.sendMessage("Hello, world!")
def onOpen(self):
self.sendHello()
def onMessage(self, msg, binary):
print "Got echo: " + msg
reactor.callLater(1, self.sendHello)
if __name__ == '__main__':
factory = WebSocketClientFactory("ws://localhost:9000")
factory.protocol = EchoClientProtocol
connectWS(factory)
reactor.run()
Add this to build.gradle
to stop gradle from swallowing stdout and stderr.
test {
testLogging.showStandardStreams = true
}
It's documented here.
MAX_EXECUTION_TIME is also an important parameter for long running queries.Will work for MySQL 5.7 or later.
Check the current value
SELECT @@GLOBAL.MAX_EXECUTION_TIME, @@SESSION.MAX_EXECUTION_TIME;
Then set it according to your needs.
SET SESSION MAX_EXECUTION_TIME=2000;
SET GLOBAL MAX_EXECUTION_TIME=2000;
I was having similar issues in my IntelliJ mvn project. Pom.xml was not recognized. What worked for me was right click on the pom.xml and then add as a maven project.
Use:
window.location.replace(...)
See this Stack Overflow question for more information:
How do I redirect to another webpage?
Or perhaps it was this you remember:
var url = "http://stackoverflow.com";
$(location).attr('href',url);
To answer your first question, the way you load a module is depending on the module entry point and the main parameter of the package.json.
Let's say you have the following file structure:
my-npm-module
|-- lib
| |-- module.js
|-- package.json
Without main parameter in the package.json, you have to load the module by giving the module entry point: require('my-npm-module/lib/module.js')
.
If you set the package.json main parameter as follows "main": "lib/module.js"
, you will be able to load the module this way: require('my-npm-module')
.
From Increase MySQL connection limit:-
MySQL’s default configuration sets the maximum simultaneous connections to 100. If you need to increase it, you can do it fairly easily:
For MySQL 3.x:
# vi /etc/my.cnf
set-variable = max_connections = 250
For MySQL 4.x and 5.x:
# vi /etc/my.cnf
max_connections = 250
Restart MySQL once you’ve made the changes and verify with:
echo "show variables like 'max_connections';" | mysql
EDIT:-(From comments)
The maximum concurrent connection can be maximum range: 4,294,967,295. Check MYSQL docs
This should do it:
private enum Alignment { LEFT, RIGHT };
String drawCellValue (int maxCellLength, String cellValue, Alignment align){
if (align == Alignment.LEFT)
{
//Process it...
}
}
Use the BEGIN TRANSACTION
command before starting queries. So that you can ROLLBACK
things at any point of time.
FOR EXAMPLE:
Django's contributed humanize application does this:
{% load humanize %}
{{ my_num|intcomma }}
Be sure to add 'django.contrib.humanize'
to your INSTALLED_APPS
list in the settings.py
file.
Perform a hard reboot of your phone. The easiest way to do this is to remove the phone's battery. Wait for at least 30 seconds, then replace the battery. The phone will reboot, and upon completing its restart will have an empty DNS cache.

Disclaimer: I am from 42matters, who provides this data already on https://42matters.com/api , feel free to check it out or drop us a line.
As lenik mentioned there are open-source libraries that already help with obtaining some data from GPlay. If you want to build one yourself you can try to parse the Google Play App page, but you should pay attention to the following:
So that in mind getting one page metadata is a matter of fetching the page html and parsing it properly. With JSoup you can try:
HttpClient httpClient = HttpClientBuilder.create().build();
HttpGet request = new HttpGet(crawlUrl);
HttpResponse rsp = httpClient.execute(request);
int statusCode = rsp.getStatusLine().getStatusCode();
if (statusCode == 200) {
String content = EntityUtils.toString(rsp.getEntity());
Document doc = Jsoup.parse(content);
//parse content, whatever you need
Element price = doc.select("[itemprop=price]").first();
}
For that very simple use case that should get you started. However, the moment you want to do more interesting stuff, things get complicated:
The list goes on. If you don't want to do all this by yourself, you can consider 42matters API, which supports lookup and search, top google charts, advanced queries and filters. And this for 35 languages and more than 50 countries.

add delim_whitespace=True
argument, it's faster than regex.
if (myReader.HasRows) //The key Word is **.HasRows**

ltlAdditional.Text = "Is null Or Empty";
}
Step 1: open your mysql workbench application select table. choose image cell right click select "Open value in Editor"
Step 2: click on the load button and choose image file
Step 3:then click apply button
Step 4: Then apply the query to save the image .Don't forgot image data type is "BLOB". Step 5: You can can check uploaded image
You can use a regular expression or some manual string fiddling, but I think I prefer:
date("d/m/Y", strtotime($str));
Use
git cherry-pick <commit-hash>
So this will pick your behind commit to git location you are on.
If you need more fine-grade control, you can also go the fork
pipe
exec
route. This will allow your application to retrieve the data outputted from the shell script.
set -x
is fine.
Another way to print each executed command is to use trap
with DEBUG
.
Put this line at the beginning of your script :
trap 'echo "# $BASH_COMMAND"' DEBUG
You can find a lot of other trap
usages here.
Another way is to use the -t
switch to ssh
:
ssh -t user@server "sudo script"
See man ssh
:
-t Force pseudo-tty allocation. This can be used to execute arbi-
trary screen-based programs on a remote machine, which can be
very useful, e.g., when implementing menu services. Multiple -t
options force tty allocation, even if ssh has no local tty.
It seems everybody is throwing their own version of the unique
filter into the ring, so I'll do the same. Critique is very welcome.
angular.module('myFilters', [])
.filter('unique', function () {
return function (items, attr) {
var seen = {};
return items.filter(function (item) {
return (angular.isUndefined(attr) || !item.hasOwnProperty(attr))
? true
: seen[item[attr]] = !seen[item[attr]];
});
};
});
You should be referencing it as localhost
. Like this:
<img src="http:\\localhost\site\img\mypicture.jpg"/>
Once focus of edit text is removed, it would not allow you to type even if you set it to focusable again.
Here is a way around it
if (someCondition)
editTextField.setFocusable(false);
else
editTextField.setFocusableInTouchMode(true);
Setting it true in setFocusableInTouchMode()
seems to do the trick.
None of above methods worked in my case i.e. changing port number in run configuration, machine restart, invalidate cache in IntelliJ, killing process shown in netstat (nestat -anob | findstr <port-number>
and then tskill <pid>
). The only thing that finally helped was starting and shutting down tomcat manually via startup.bat
and shutdown.bat
(you should use correspondig .sh
files on linux and macOS).
If you downloaded mySQL using a DMG (easiest way to download found here http://dev.mysql.com/downloads/mysql/) in Terminal try: cd /usr/local/
When you type ls
you should see mysql-YOUR-VERSION. You will also see mysql which is the installation directory.
Some of you might find this useful. Just copy paste it to your page and you will get a sequence in which events are fired in the Chrome console (Ctrl + Shift + I).
$(document).on('pagebeforecreate',function(){console.log('pagebeforecreate');});
$(document).on('pagecreate',function(){console.log('pagecreate');});
$(document).on('pageinit',function(){console.log('pageinit');});
$(document).on('pagebeforehide',function(){console.log('pagebeforehide');});
$(document).on('pagebeforeshow',function(){console.log('pagebeforeshow');});
$(document).on('pageremove',function(){console.log('pageremove');});
$(document).on('pageshow',function(){console.log('pageshow');});
$(document).on('pagehide',function(){console.log('pagehide');});
$(window).load(function () {console.log("window loaded");});
$(window).unload(function () {console.log("window unloaded");});
$(function () {console.log('document ready');});
You are not going see unload in the console as it is fired when the page is being unloaded (when you move away from the page). Use it like this:
$(window).unload(function () { debugger; console.log("window unloaded");});
And you will see what I mean.
also you can use this code (pure python by 3 byte of header file):
full_path = os.path.join(MEDIA_ROOT, pathfile)
try:
image_data = open(full_path, "rb").read()
except IOError:
return "Incorrect Request :( !!!"
header_byte = image_data[0:3].encode("hex").lower()
if header_byte == '474946':
return "image/gif"
elif header_byte == '89504e':
return "image/png"
elif header_byte == 'ffd8ff':
return "image/jpeg"
else:
return "binary file"
without any package install [and update version]
You can use the following:
/// <summary>
/// Serializes an object.

/// <param name="serializableObject"></param>
/// <param name="fileName"></param>
public void SerializeObject<T>(T serializableObject, string fileName)
{
if (serializableObject == null) { return; }
try
{
XmlDocument xmlDocument = new XmlDocument();
XmlSerializer serializer = new XmlSerializer(serializableObject.GetType());
using (MemoryStream stream = new MemoryStream())
{
serializer.Serialize(stream, serializableObject);
stream.Position = 0;
xmlDocument.Load(stream);
xmlDocument.Save(fileName);
}
}
catch (Exception ex)
{
//Log exception here
}
}
/// <summary>

public T DeSerializeObject<T>(string fileName)
{
if (string.IsNullOrEmpty(fileName)) { return default(T); }
T objectOut = default(T);
try
{
XmlDocument xmlDocument = new XmlDocument();
xmlDocument.Load(fileName);
string xmlString = xmlDocument.OuterXml;
using (StringReader read = new StringReader(xmlString))
{
Type outType = typeof(T);
XmlSerializer serializer = new XmlSerializer(outType);
using (XmlReader reader = new XmlTextReader(read))
{
objectOut = (T)serializer.Deserialize(reader);
}
}
}
catch (Exception ex)
{
//Log exception here
}
return objectOut;
}
Using the Promise pattern:
function getImage(url){
return new Promise(function(resolve, reject){
var img = new Image()
img.onload = function(){
resolve(url)
}
img.onerror = function(){
reject(url)
}
img.src = url
})
}
And when calling the function we can handle its response or error quite neatly.
getImage('imgUrl').then(function(successUrl){
//do stufff
}).catch(function(errorUrl){
//do stuff
})
Here's something I use to convert excel column letters to numbers (so a limit of 3 letters but it's pretty easy to extend this out if you need more). Probably not the best way but it works for what I need it for.
def letter_to_number(letters):
letters = letters.lower()
dictionary = {'a':1,'b':2,'c':3,'d':4,'e':5,'f':6,'g':7,'h':8,'i':9,'j':10,'k':11,'l':12,'m':13,'n':14,'o':15,'p':16,'q':17,'r':18,'s':19,'t':20,'u':21,'v':22,'w':23,'x':24,'y':25,'z':26}
strlen = len(letters)
if strlen == 1:
number = dictionary[letters]
elif strlen == 2:
first_letter = letters[0]
first_number = dictionary[first_letter]
second_letter = letters[1]
second_number = dictionary[second_letter]
number = (first_number * 26) + second_number
elif strlen == 3:
first_letter = letters[0]
first_number = dictionary[first_letter]
second_letter = letters[1]
second_number = dictionary[second_letter]
third_letter = letters[2]
third_number = dictionary[third_letter]
number = (first_number * 26 * 26) + (second_number * 26) + third_number
return number

I would like to improve Evan Knowles answer: https://stackoverflow.com/a/30796829/2628125
In my case I had class with handlers for UI Component part. Initialization:
this.dataText.textProperty().addListener((observable, oldValue, newValue) -> this.numericSanitization(observable, oldValue, newValue));
And the numbericSanitization method:
private synchronized void numericSanitization(ObservableValue<? extends String> observable, String oldValue, String newValue) {
final String allowedPattern = "\\d*";
if (!newValue.matches(allowedPattern)) {
this.dataText.setText(oldValue);
}
}
Keyword synchronized is added to prevent possible render lock issue in javafx if setText will be called before old one is finished execution. It is easy to reproduce if you will start typing wrong chars really fast.
Another advantage is that you keep only one pattern to match and just do rollback. It is better because you can easily abstragate solution for different sanitization patterns.
Don't use array_values
on your $row
$res_arr_values = array();
while ($row = mysql_fetch_array($result, MYSQL_ASSOC))
{
array_push($res_arr_values, $row);
}
Also, the preferred way to add a value to an array is writing $array[] = $value;
, not using array_push
$res_arr_values = array();
while ($row = mysql_fetch_array($result, MYSQL_ASSOC))
{
$res_arr_values[] = $row;
}
And a further optimization is not to call mysql_fetch_array($result, MYSQL_ASSOC)
but to use mysql_fetch_assoc($result)
directly.
$res_arr_values = array();
while ($row = mysql_fetch_assoc($result))
{
$res_arr_values[] = $row;
}
For nested JSON plain text
db.model.findAll({

nest : true
})
$(".clscss-row").each(function () {

} });
Use this syntax:
obj[name]
Note that obj.x
is the same as obj["x"]
for all valid JS identifiers, but the latter form accepts all string as keys (not just valid identifiers).
obj["Hey, this is ... neat?"] = 42
There is no way to do it in JavaScript natively. (See Riccardo Galli's answer for a modern approach.)
For historical reference or where TextEncoder APIs are still unavailable.
If you know the character encoding, you can calculate it yourself though.
encodeURIComponent
assumes UTF-8 as the character encoding, so if you need that encoding, you can do,
function lengthInUtf8Bytes(str) {
// Matches only the 10.. bytes that are non-initial characters in a multi-byte sequence.
var m = encodeURIComponent(str).match(/%[89ABab]/g);
return str.length + (m ? m.length : 0);
}
This should work because of the way UTF-8 encodes multi-byte sequences. The first encoded byte always starts with either a high bit of zero for a single byte sequence, or a byte whose first hex digit is C, D, E, or F. The second and subsequent bytes are the ones whose first two bits are 10. Those are the extra bytes you want to count in UTF-8.
The table in wikipedia makes it clearer
Bits Last code point Byte 1 Byte 2 Byte 3
7 U+007F 0xxxxxxx
11 U+07FF 110xxxxx 10xxxxxx
16 U+FFFF 1110xxxx 10xxxxxx 10xxxxxx
...
If instead you need to understand the page encoding, you can use this trick:
function lengthInPageEncoding(s) {
var a = document.createElement('A');
a.href = '#' + s;
var sEncoded = a.href;
sEncoded = sEncoded.substring(sEncoded.indexOf('#') + 1);
var m = sEncoded.match(/%[0-9a-f]{2}/g);
return sEncoded.length - (m ? m.length * 2 : 0);
}
Create Function
function toggleFullScreen() {
if ((document.fullScreenElement && document.fullScreenElement !== null) ||
(!document.mozFullScreen && !document.webkitIsFullScreen)) {
$scope.topMenuData.showSmall = true;
if (document.documentElement.requestFullScreen) {
document.documentElement.requestFullScreen();
} else if (document.documentElement.mozRequestFullScreen) {
document.documentElement.mozRequestFullScreen();
} else if (document.documentElement.webkitRequestFullScreen) {
document.documentElement.webkitRequestFullScreen(Element.ALLOW_KEYBOARD_INPUT);
}
} else {
$scope.topMenuData.showSmall = false;
if (document.cancelFullScreen) {
document.cancelFullScreen();
} else if (document.mozCancelFullScreen) {
document.mozCancelFullScreen();
} else if (document.webkitCancelFullScreen) {
document.webkitCancelFullScreen();
}
}
}
In Html Put Code like
<ul class="unstyled-list fg-white">
<li class="place-right" data-ng-if="!topMenuData.showSmall" data-ng-click="toggleFullScreen()">Full Screen</li>
<li class="place-right" data-ng-if="topMenuData.showSmall" data-ng-click="toggleFullScreen()">Back</li>
</ul>
Since Oracle 9i there are two ways or declaring a directory for use with UTL_FILE.
The older way is to set the INIT.ORA parameter UTL_FILE_DIR. We have to restart the database for a change to take affect. The value can like any other PATH variable; it accepts wildcards. Using this approach means passing the directory path...
UTL_FILE.FOPEN('c:\temp', 'vineet.txt', 'W');
The alternative approach is to declare a directory object.
create or replace directory temp_dir as 'C:\temp'
/
grant read, write on directory temp_dir to vineet
/
Directory objects require the exact file path, and don't accept wildcards. In this approach we pass the directory object name...
UTL_FILE.FOPEN('TEMP_DIR', 'vineet.txt', 'W');
The UTL_FILE_DIR is deprecated because it is inherently insecure - all users have access to all the OS directories specified in the path, whereas read and write privileges can de granted discretely to individual users. Also, with Directory objects we can be add, remove or change directories without bouncing the database.
In either case, the oracle
OS user must have read and/or write privileges on the OS directory. In case it isn't obvious, this means the directory must be visible from the database server. So we cannot use either approach to expose a directory on our local PC to a process running on a remote database server. Files must be uploaded to the database server, or a shared network drive.
If the oracle
OS user does not have the appropriate privileges on the OS directory, or if the path specified in the database does not match to an actual path, the program will hurl this exception:
ORA-29283: invalid file operation
ORA-06512: at "SYS.UTL_FILE", line 536
ORA-29283: invalid file operation
ORA-06512: at line 7
The OERR text for this error is pretty clear:
29283 - "invalid file operation"
*Cause: An attempt was made to read from a file or directory that does
not exist, or file or directory access was denied by the
operating system.
*Action: Verify file and directory access privileges on the file system,
and if reading, verify that the file exists.
This is a common function of Adorners in WPF. Adorners typically appear above all other controls, but the other answers that mention z-order may fit your case better.
Make sure the hamcrest jar is higher on the import order than your JUnit jar.
JUnit comes with its own org.hamcrest.Matcher
class that is probably being used instead.
You can also download and use the junit-dep-4.10.jar instead which is JUnit without the hamcrest classes.
mockito also has the hamcrest classes in it as well, so you may need to move\reorder it as well
I actually just found that if you want to add multiple rows below the selection in your table
Selection.ListObject.ListRows.Add AlwaysInsert:=True
works really well. I just duplicated the code five times to add five rows to my table
in the first you should make form like this :
<form method="post" enctype="multipart/form-data" >
<input type="file" name="file[]" multiple id="file"/>
<input type="submit" name="ok" />
</form>
that is right . now add this code under your form code or on the any page you like
<?php
if(isset($_POST['ok']))
foreach ($_FILES['file']['name'] as $filename) {
echo $filename.'<br/>';
}
?>
it's easy... finish
Possibilities:
Use String.equals()
:
if (some_string.equals("john") ||
some_string.equals("mary") ||
some_string.equals("peter"))
{
}
Use a regular expression:
if (some_string.matches("john|mary|peter"))
{
}
Store a list of strings to be matched against in a Collection and search the collection:
Set<String> names = new HashSet<String>();
names.add("john");
names.add("mary");
names.add("peter");
if (names.contains(some_string))
{
}
I might argue that the answer here generally is "don't". Unless you absolutely need all the data at once, consider using a Stream
-based API (or some variant of reader / iterator). That is especially important when you have multiple parallel operations (as suggested by the question) to minimise system load and maximise throughput.
For example, if you are streaming data to a caller:
Stream dest = ...
using(Stream source = File.OpenRead(path)) {
byte[] buffer = new byte[2048];
int bytesRead;
while((bytesRead = source.Read(buffer, 0, buffer.Length)) > 0) {
dest.Write(buffer, 0, bytesRead);
}
}
I always set the max like this:
<EditText
android:id="@+id/edit_blaze_it
android:layout_width="0dp"
android:layout_height="@dimen/too_high"
<!-- This is the line you need to write to set the max-->
android:maxLength="420"
/>
If using MS Access (especially older versions like 2003) you are forced to use TEXT
datatype on SQL Server as MS Access does not recognize nvarchar(MAX)
as a Memo field in Access, whereas TEXT
is recognized as a Memo-field.
Currently, there is no C# class that correctly handles ISO 8601week numbers. Even though you can instantiate a culture, look for the closest thing and correct that, I think it is better to do the complete calculation yourself:
/// <summary>
/// Converts a date to a week number.
/// ISO 8601 week 1 is the week that contains the first Thursday that year.
/// </summary>
public static int ToIso8601Weeknumber(this DateTime date)
{
var thursday = date.AddDays(3 - date.DayOfWeek.DayOffset());
return (thursday.DayOfYear - 1) / 7 + 1;
}
/// <summary>
/// Converts a week number to a date.
/// Note: Week 1 of a year may start in the previous year.
/// ISO 8601 week 1 is the week that contains the first Thursday that year, so
/// if December 28 is a Monday, December 31 is a Thursday,
/// and week 1 starts January 4.
/// If December 28 is a later day in the week, week 1 starts earlier.
/// If December 28 is a Sunday, it is in the same week as Thursday January 1.
/// </summary>
public static DateTime FromIso8601Weeknumber(int weekNumber, int? year = null, DayOfWeek day = DayOfWeek.Monday)
{
var dec28 = new DateTime((year ?? DateTime.Today.Year) - 1, 12, 28);
var monday = dec28.AddDays(7 * weekNumber - dec28.DayOfWeek.DayOffset());
return monday.AddDays(day.DayOffset());
}
/// <summary>
/// Iso8601 weeks start on Monday. This returns 0 for Monday.
/// </summary>
private static int DayOffset(this DayOfWeek weekDay)
{
return ((int)weekDay + 6) % 7;
}

I've made very simple function for marquee. See: http://jsfiddle.net/vivekw/pHNpk/2/ It pauses on mouseover & resumes on mouseleave. Speed can be varied. Easy to understand.
function marquee(a, b) {
var width = b.width();
var start_pos = a.width();
var end_pos = -width;
function scroll() {
if (b.position().left <= -width) {
b.css('left', start_pos);
scroll();
}
else {
time = (parseInt(b.position().left, 10) - end_pos) *
(10000 / (start_pos - end_pos)); // Increase or decrease speed by changing value 10000
b.animate({
'left': -width
}, time, 'linear', function() {
scroll();
});
}
}
b.css({
'width': width,
'left': start_pos
});
scroll(a, b);
b.mouseenter(function() { // Remove these lines
b.stop(); //
b.clearQueue(); // if you don't want
}); //
b.mouseleave(function() { // marquee to pause
scroll(a, b); //
}); // on mouse over
}
$(document).ready(function() {
marquee($('#display'), $('#text')); //Enter name of container element & marquee element
});
All tables within the bootstrap stretch according to their container, which you can easily do by placing your table inside a .span*
grid element of your choice. If you wish to remove this property you can create your own table class and simply add it to the table you want to expand with the content within:
.table-nonfluid {
width: auto !important;
}
You can add this class inside your own stylesheet and simply add it to the container of your table like so:
<table class="table table-nonfluid"> ... </table>
This way your change won't affect the bootstrap stylesheet itself (you might want to have a fluid table somewhere else in your document).
In my case even though I used all the solutions mentioned above but nothing worked for me. So I decided to uninstall docker and install it again.
Now in the process, I have noticed that I did not check Use Windows containers instead of Linux containers (this can be changed after installation)
in my previous installation, and that is why I got the problem above and the solutions still did not fix it. So ensure to check it before you run desktop docker or uninstall it and install it again by checking this option.
The accepted answer calls the draw
function twice. I can't see why that would be needed. In fact, if your new data has the same columns as the old data, you can accomplish this in one line:
datatable.clear().rows.add(newData).draw();
//user113716 code is working but i altered as below. it will work if your URL contain "?" mark or not
//replace URL in browser
if(window.location.href.indexOf("?") > -1) {
var newUrl = refineUrl();
window.history.pushState("object or string", "Title", "/"+newUrl );
}
function refineUrl()
{
//get full url
var url = window.location.href;
//get url after/
var value = url = url.slice( 0, url.indexOf('?') );
//get the part after before ?
value = value.replace('@System.Web.Configuration.WebConfigurationManager.AppSettings["BaseURL"]','');
return value;
}
For input you must have used value
to grab its text but for td, you should use innerHTML
to get its html/value. Example:
alert(document.getElementById("td_id_here").innerHTML);
To get its text though, use:
alert(document.getElementById("td_id_here").innerText);
df.loc[df['A'] == df['B'], 'C'] = 0
df.loc[df['A'] > df['B'], 'C'] = 1
df.loc[df['A'] < df['B'], 'C'] = -1
Easy to solve using indexing. The first line of code reads like so, if column A
is equal to column B
then create and set column C
equal to 0.
It took me a little while but finally figured out. Custom xpath that contains some text below worked perfectly for me.
//a[contains(text(),'JB-')]
I'm still working on a better solution but using MOXy JAXB, I've been able to handle the following XML:
<?xml version="1.0" encoding="UTF-8"?>
<root>
<mapProperty>
<map>
<key>value</key>
<key2>value2</key2>
</map>
</mapProperty>
</root>
You need to use an @XmlJavaTypeAdapter on your Map property:
import java.util.HashMap;
import java.util.Map;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.adapters.XmlJavaTypeAdapter;
@XmlRootElement
public class Root {
private Map<String, String> mapProperty;
public Root() {
mapProperty = new HashMap<String, String>();
}
@XmlJavaTypeAdapter(MapAdapter.class)
public Map<String, String> getMapProperty() {
return mapProperty;
}
public void setMapProperty(Map<String, String> map) {
this.mapProperty = map;
}
}
The implementation of the XmlAdapter is as follows:
import java.util.HashMap;
import java.util.Map;
import java.util.Map.Entry;
import javax.xml.bind.annotation.adapters.XmlAdapter;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;
public class MapAdapter extends XmlAdapter<AdaptedMap, Map<String, String>> {
@Override
public AdaptedMap marshal(Map<String, String> map) throws Exception {
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document document = db.newDocument();
Element rootElement = document.createElement("map");
document.appendChild(rootElement);
for(Entry<String,String> entry : map.entrySet()) {
Element mapElement = document.createElement(entry.getKey());
mapElement.setTextContent(entry.getValue());
rootElement.appendChild(mapElement);
}
AdaptedMap adaptedMap = new AdaptedMap();
adaptedMap.setValue(document);
return adaptedMap;
}
@Override
public Map<String, String> unmarshal(AdaptedMap adaptedMap) throws Exception {
Map<String, String> map = new HashMap<String, String>();
Element rootElement = (Element) adaptedMap.getValue();
NodeList childNodes = rootElement.getChildNodes();
for(int x=0,size=childNodes.getLength(); x<size; x++) {
Node childNode = childNodes.item(x);
if(childNode.getNodeType() == Node.ELEMENT_NODE) {
map.put(childNode.getLocalName(), childNode.getTextContent());
}
}
return map;
}
}
The AdpatedMap class is where all the magic happens, we will use a DOM to represent the content. We will trick JAXB intro dealing with a DOM through the combination of @XmlAnyElement and a property of type Object:
import javax.xml.bind.annotation.XmlAnyElement;
public class AdaptedMap {
private Object value;
@XmlAnyElement
public Object getValue() {
return value;
}
public void setValue(Object value) {
this.value = value;
}
}
This solution requires the MOXy JAXB implementation. You can configure the JAXB runtime to use the MOXy implementation by adding a file named jaxb.properties in with your model classes with the following entry:
javax.xml.bind.context.factory=org.eclipse.persistence.jaxb.JAXBContextFactory
The following demo code can be used to verify the code:
import java.io.File;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.Marshaller;
import javax.xml.bind.Unmarshaller;
public class Demo {
public static void main(String[] args) throws Exception {
JAXBContext jc = JAXBContext.newInstance(Root.class);
Unmarshaller unmarshaller = jc.createUnmarshaller();
Root root = (Root) unmarshaller.unmarshal(new File("src/forum74/input.xml"));
Marshaller marshaller = jc.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
marshaller.marshal(root, System.out);
}
}
Try use absolute path:
exclude:path.resolve(__dirname, "node_modules")
The problem is due to having jQuery instances more than one time. Take care if you are using many files with multiples instance of jQuery. Just leave 1 instance of jQuery and your code will work.
<script type="text/javascript" src="https://code.jquery.com/jquery-2.1.4.min.js"></script>
the way I use jsonp like below:
function jsonp(uri) {
return new Promise(function(resolve, reject) {
var id = '_' + Math.round(10000 * Math.random());
var callbackName = 'jsonp_callback_' + id;
window[callbackName] = function(data) {
delete window[callbackName];
var ele = document.getElementById(id);
ele.parentNode.removeChild(ele);
resolve(data);
}
var src = uri + '&callback=' + callbackName;
var script = document.createElement('script');
script.src = src;
script.id = id;
script.addEventListener('error', reject);
(document.getElementsByTagName('head')[0] || document.body || document.documentElement).appendChild(script)
});
}
then use 'jsonp' method like this:
jsonp('http://xxx/cors').then(function(data){
console.log(data);
});

Console
outputs to the console window and Winforms applications do not show the console window. You should be able to use System.Diagnostics.Debug.WriteLine
to send output to the output window in your IDE.
Edit: In regards to the problem, have you verified your mainForm_Load
is actually being called? You could place a breakpoint at the beginning of mainForm_Load
to see. If it is not being called, I suspect that mainForm_Load
is not hooked up to the Load
event.
Also, it is more efficient and generally better to override On{EventName}
instead of subscribing to {EventName}
from within derived classes (in your case overriding OnLoad
instead of Load
).
Here is what I use.
Write-Host -NoNewLine 'Press any key to continue...';
$null = $Host.UI.RawUI.ReadKey('NoEcho,IncludeKeyDown');
I know it's not an answer to the exact question asked, but I found this question looking to diff a file in a branch and a local uncommitted file and I figured I would share
Syntax:
git diff <commit-ish>:./ -- <path>
Examples:
git diff origin/master:./ -- README.md
git diff HEAD^:./ -- README.md
git diff stash@{0}:./ -- README.md
git diff 1A2B3C4D:./ -- README.md
(Thanks Eric Boehs for a way to not have to type the filename twice)
I am not sure if this will work for your situation, but often [map][1] is a good answer.
If this was your code with the for
loop:
<tbody>
for (var i=0; i < objects.length; i++) {
<ObjectRow obj={objects[i]} key={i}>
}
</tbody>
You could write it like this with the map
function:
<tbody>
{objects.map(function(object, i){
return <ObjectRow obj={object} key={i} />;
})}
</tbody>
objects.map
is the best way to do a loop, and objects.filter
is the best way to filter the required data. The filtered data will form a new array, and objects.some
is the best way to check whether the array satisfies the given condition (it returns Boolean).
The selected answer would work for as long as you know the key itself that you want to delete but if it should be truly dynamic you would need to use the [] notation instead of the dot notation.
For example:
var keyToDelete = "key1";
var myObj = {"test": {"key1": "value", "key2": "value"}}
//that will not work.
delete myObj.test.keyToDelete
instead you would need to use:
delete myObj.test[keyToDelete];
Substitute the dot notation with [] notation for those values that you want evaluated before being deleted.
First, you need to create selfsigned.key and selfsigned.crt files. Go to Create a Self-Signed SSL Certificate Or do following steps.
Go to the terminal and run the following command.
sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout ./selfsigned.key -out selfsigned.crt
After creation adds key & cert file in your code, and pass the options to the server.
const express = require('express');
const https = require('https');
const fs = require('fs');
const port = 3000;
var key = fs.readFileSync(__dirname + '/../certs/selfsigned.key');
var cert = fs.readFileSync(__dirname + '/../certs/selfsigned.crt');
var options = {
key: key,
cert: cert
};
app = express()
app.get('/', (req, res) => {
res.send('Now using https..');
});
var server = https.createServer(options, app);
server.listen(port, () => {
console.log("server starting on port : " + port)
});

Here's a question and answer for this: Difference between screen.availHeight and window.height()
Has pics too, so you can actually see the differences. Hope this helps.
Basically, $(window).height()
give you the maximum height inside of the browser window (viewport), and$(document).height()
gives you the height of the document inside of the browser. Most of the time, they will be exactly the same, even with scrollbars.
To fix your code you can simply change [Cov]
to Cov.values
, the first parameter of pd.DataFrame
will become a multi-dimensional numpy
array:
Cov = pd.read_csv("path/to/file.txt", sep='\t')
Frame=pd.DataFrame(Cov.values, columns = ["Sequence", "Start", "End", "Coverage"])
Frame.to_csv("path/to/file.txt", sep='\t')
But the smartest solution still is use pd.read_excel
with header=None
and names=columns_list
.
With SQL Server 2012 and onward you can use the FORMAT
function
SELECT FORMAT(GETDATE(), 'dddd')
You can use Linq to XML to do this:
XDocument doc = XDocument.Load("input.xml");
var q = from node in doc.Descendants("Setting")
let attr = node.Attribute("name")
where attr != null && attr.Value == "File1"
select node;
q.ToList().ForEach(x => x.Remove());
doc.Save("output.xml");
Test empty or blank string (shorter way):
if myString.strip():
print("it's not an empty or blank string")
else:
print("it's an empty or blank string")
You can change the matplotlib using backend using the from agg
to Tkinter TKAgg
using command
matplotlib.use('TKAgg',warn=False, force=True)
git rev-list --all | (
while read revision; do
git grep -F 'password' $revision
done
)
Should be .\SQLExpress
or localhost\SQLExpress

In case this is useful to anyone I had this same issue. I was bringing in a footer into a web page via jQuery. Inside that footer were some Google scripts for ads and retargeting. I had to move those scripts from the footer and place them directly in the page and that eliminated the notice.
After using session_destroy()
, the session is destroyed behind the scenes. For some reason this doesn't affect the values in $_SESSION
, which was already populated for this request, but it will be empty in future requests.
You can manually clear $_SESSION
if you so desire ($_SESSION = [];
).
I can't imagine how you've gone this long without using a do...while
loop.
There's one on another monitor right now and there are multiple such loops in that program. They're all of the form:
do
{
GetProspectiveResult();
}
while (!ProspectIsGood());
To read from relative path on the system use System.getProperty method to get current directory and further uses to load the file using relative path.
scala> val path = System.getProperty("user.dir").concat("/../2015-summary.csv")
scala> val csvDf = spark.read.option("inferSchema","true").option("header", "true").csv(path)
scala> csvDf.take(3)
spark:2.4.4 scala:2.11.12
First set position
of the parent DIV to relative
(specifying the offset, i.e. left
, top
etc. is not necessary) and then apply position: absolute
to the child DIV with the offset you want.
It's simple and should do the trick well.
The quick and dirty way to check what string you need it to look at the generated .resources files.
Your .resources are generated in the resources projects obj/Debug directory. (if not right click on .resx file in solution explorer and hit 'Run Custom Tool' to generate the .resources files)
Navigate to this directory and have a look at the filenames. You should see a file ending in XYZ.resources. Copy that filename and remove the trailing .resources and that is the file you should be loading.
For example in my obj/Bin directory I have the file:
MyLocalisation.Properties.Resources.resources
If the resource files are in the same Class library/Application I would use the following C#
ResourceManager RM = new ResourceManager("MyLocalisation.Properties.Resources", Assembly.GetExecutingAssembly());
However, as it sounds like you are using the resources file from a separate Class library/Application you probably want
Assembly localisationAssembly = Assembly.Load("MyLocalisation");
ResourceManager RM = new ResourceManager("MyLocalisation.Properties.Resources", localisationAssembly);
Here's a trick that worked for me:
handleClick = e => {
if (e.target === e.currentTarget) {
// do something
} else {
// do something else
}
}
Explanation: I attached handleClick
to a backdrop of a modal window, but it also fired on every click inside of a modal window (because it was IN the backdrop div). So I added the condition (e.target === e.currentTarget)
, which is only fulfilled when a backdrop is clicked.
I think you were planning to use Angular template reference variable based on your html template.
// in html
<input #nameInput type="text" class="form-control" placeholder=''/>
// in add-player.ts file
import { OnInit, ViewChild, ElementRef } from '@angular/core';
export class AddPlayerComponent implements OnInit {
@ViewChild('nameInput') nameInput: ElementRef;
constructor() { }
ngOnInit() { }
addPlayer() {
// you can access the input value via the following syntax.
console.log('player name: ', this.nameInput.nativeElement.value);
}
}

I am not sure whether anyone faced issues with getting the whole string "test from adb". Using the escape character in front of the space worked for me.
adb shell am broadcast -a com.whereismywifeserver.intent.TEST --es sms_body "test\ from\ adb" -n com.whereismywifeserver/.IntentReceiver
Personally, I do not accept a whitespace ($STR3) as being 'not empty'.
When a variable that only contains whitespaces is passed onto a parameter, it will often error that the parameters value may not be '$null', instead of saying it may not be a whitespace, some remove commands might remove a root folder instead of a subfolder if the subfolder name is a "white space", all the reason not to accept a string containing whitespaces in many cases.
I find this is the best way to accomplish it:
$STR1 = $null
IF ([string]::IsNullOrWhitespace($STR1)){'empty'} else {'not empty'}
Empty
$STR2 = ""
IF ([string]::IsNullOrWhitespace($STR2)){'empty'} else {'not empty'}
Empty
$STR3 = " "
IF ([string]::IsNullOrWhitespace($STR3)){'empty !! :-)'} else {'not Empty :-('}
Empty!! :-)
$STR4 = "Nico"
IF ([string]::IsNullOrWhitespace($STR4)){'empty'} else {'not empty'}
Not empty
Thanks for the clues provided by you guys, especially @SmartLemon, I got the solution. In case someone else need it, I put my final solution here( to find the first listed external SD card ):
public File getExternalSDCardDirectory()
{
File innerDir = Environment.getExternalStorageDirectory();
File rootDir = innerDir.getParentFile();
File firstExtSdCard = innerDir ;
File[] files = rootDir.listFiles();
for (File file : files) {
if (file.compareTo(innerDir) != 0) {
firstExtSdCard = file;
break;
}
}
//Log.i("2", firstExtSdCard.getAbsolutePath().toString());
return firstExtSdCard;
}
If no external SD card there, then it returns the on board storage. I will use it if the sdcard is not exist, you may need to change it.
You can alternatively use recv(x_bytes, socket.MSG_WAITALL)
, which seems to work only on Unix, and will return exactly x_bytes
.

List<EmailData> lstemail = new List<EmailData>();

I got similar results:

In Year 2019, we can use Javascript's ES6 Spread syntax to do it concisely and efficiently
data = [...data, {"label": 2, "value": 13}]
Examples
var data = [_x000D_
{"label" : "1", "value" : 12},_x000D_
{"label" : "1", "value" : 12},_x000D_
{"label" : "1", "value" : 12},_x000D_
];_x000D_
_x000D_
data = [...data, {"label" : "2", "value" : 14}] _x000D_
console.log(data)
_x000D_
For your case (i know it was in 2011), we can do it with map() & forEach() like below
var lab = ["1","2","3","4"];_x000D_
var val = [42,55,51,22];_x000D_
_x000D_
//Using forEach()_x000D_
var data = [];_x000D_
val.forEach((v,i) => _x000D_
data= [...data, {"label": lab[i], "value":v}]_x000D_
)_x000D_
_x000D_
//Using map()_x000D_
var dataMap = val.map((v,i) => _x000D_
({"label": lab[i], "value":v})_x000D_

Lots of people have mentioned Functional Languages.
But some of the Most commonly used Functional Languages in use today besides Javascript.
Excel, SQL, XSLT, XQuery, J and K are used in financial realm.
Of course Erlang.
So I would say that from that list that Functional Programming techniques are used in mainstream every day.
To find a very long list of words in big files, it can be more efficient to use egrep:
remove the last \n of A
$ tr '\n' '|' < A > A_regex
$ egrep -f A_regex B
If the column is not in the WHERE/JOIN/GROUP BY/ORDER BY
, but only in the column list in the SELECT
clause is where you use INCLUDE
.
The INCLUDE
clause adds the data at the lowest/leaf level, rather than in the index tree.
This makes the index smaller because it's not part of the tree
INCLUDE columns
are not key columns in the index, so they are not ordered.
This means it isn't really useful for predicates, sorting etc as I mentioned above. However, it may be useful if you have a residual lookup in a few rows from the key column(s)
What you want to do is referred to as "squashing" in git. There are lots of options when you're doing this (too many?) but if you just want to merge all of your unpushed commits into a single commit, do this:
git rebase -i origin/master
This will bring up your text editor (-i
is for "interactive") with a file that looks like this:
pick 16b5fcc Code in, tests not passing
pick c964dea Getting closer
pick 06cf8ee Something changed
pick 396b4a3 Tests pass
pick 9be7fdb Better comments
pick 7dba9cb All done
Change all the pick
to squash
(or s
) except the first one:
pick 16b5fcc Code in, tests not passing
squash c964dea Getting closer
squash 06cf8ee Something changed
squash 396b4a3 Tests pass
squash 9be7fdb Better comments
squash 7dba9cb All done
Save your file and exit your editor. Then another text editor will open to let you combine the commit messages from all of the commits into one big commit message.
Voila! Googling "git squashing" will give you explanations of all the other options available.
If you never want to have duplicates, you should declare this as a table constraint:
CREATE TABLE bookmarks(
users_id INTEGER,
lessoninfo_id INTEGER,
UNIQUE(users_id, lessoninfo_id)
);
(A primary key over both columns would have the same effect.)
It is then possible to tell the database that you want to silently ignore records that would violate such a constraint:
INSERT OR IGNORE INTO bookmarks(users_id, lessoninfo_id) VALUES(123, 456)
Every object of the Class BigDecimal
has a method compareTo
you can use to compare it to another BigDecimal. The result of compareTo
is then compared > 0
, == 0
or < 0
depending on what you need. Read the documentation and you will find out.
The operators ==
, <
, >
and so on can only be used on primitive data types like int
, long
, double
or their wrapper classes like Integer
and Double
.
From the documentation of compareTo
:
Compares this
BigDecimal
with the specifiedBigDecimal
.Two
BigDecimal
objects that are equal in value but have a different scale (like 2.0 and 2.00) are considered equal by this method. This method is provided in preference to individual methods for each of the six boolean comparison operators (<, ==, >, >=, !=, <=). The suggested idiom for performing these comparisons is:(x.compareTo(y) <op> 0)
, where<op>
is one of the six comparison operators.Returns: -1, 0, or 1 as this BigDecimal is numerically less than, equal to, or greater than val.
Instead of using an enum use a static class.
replace
private enum PublishStatuses{
NotCompleted,
Completed,
Error
};
with
private static class PublishStatuses{
public static readonly string NotCompleted = "Not Completed";
public static readonly string Completed = "Completed";
public static readonly string Error = "Error";
};
it will be used like this
PublishStatuses.NotCompleted; // "Not Completed"
Issue using the top "extension method" solutions:
A private enum is often used inside another class. The extension method solution is not valid there since it must be in it's own class. This solution can be private and embedded in another class.
Here the defination of Rendersection from MSDN
In layout pages, renders the content of a named section.MSDN
In _layout.cs page put
@RenderSection("Bottom",false)
Here render the content of bootom section and specifies false
boolean property to specify whether the section is required or not.
@section Bottom{
This message form bottom.
}
That meaning if you want to bottom section in all pages, then you must use false as the second parameter at Rendersection method.
You can see all the version of a module with npm view
.
eg: To list all versions of bootstrap including beta.
npm view bootstrap versions
But if the version list is very big it will truncate. An --json
option will print all version including beta versions as well.
npm view bootstrap versions --json
If you want to list only the stable versions not the beta then use singular version
npm view bootstrap@* versions
Or
npm view bootstrap@* versions --json
And, if you want to see only latest version then here you go.
npm view bootstrap version
You don't mention if this is an anonymous PL/SQL block or a declarative one ie. Package, Procedure or Function. However, in PL/SQL a COMMIT must be explicitly made to save your transaction(s) to the database. The COMMIT actually saves all unsaved transactions to the database from your current user's session.
If an error occurs the transaction implicitly does a ROLLBACK.
This is the default behaviour for PL/SQL.
Important benefit of the dynamic resources
if application startup takes extremely long time, you must use dynamic resources, because static resources are always loaded when the window or app is created, while dynamic resources are loaded when they’re first used.
However, you won’t see any benefit unless your resource is extremely large and complex.
We can create alternative of implode of in javascript:
function my_implode_js(separator,array){
var temp = '';
for(var i=0;i<array.length;i++){
temp += array[i]
if(i!=array.length-1){
temp += separator ;
}
}//end of the for loop
return temp;
}//end of the function
var array = new Array("One", "Two", "Three");
var str = my_implode_js('-',array);
alert(str);
try using INSTALL_ROOT.
make install INSTALL_ROOT=$INSTALL_DIRECTORY
Sure, just add &
after the command:
read_cfg cfgA &
read_cfg cfgB &
read_cfg cfgC &
wait
all those jobs will then run in the background simultaneously. The optional wait
command will then wait for all the jobs to finish.
Each command will run in a separate process, so it's technically not "multithreading", but I believe it solves your problem.

I think the simplest way is that:
type InputEvent = React.ChangeEvent<HTMLInputElement>;
type ButtonEvent = React.MouseEvent<HTMLButtonElement>;
update = (e: InputEvent): void => this.props.login[e.target.name] = e.target.value;
submit = (e: ButtonEvent): void => {
this.props.login.logIn();
e.preventDefault();
}

To see exactly what is happening, use nc -l
and an user agent like a browser or cURL.
Save the form to an .html
file:
<form action="http://localhost:8000" method="post" enctype="multipart/form-data">
<p><input type="text" name="text" value="text default">
<p><input type="file" name="file1">
<p><input type="file" name="file2">
<p><button type="submit">Submit</button>
</form>
Create files to upload:
echo 'Content of a.txt.' > a.txt
echo '<!DOCTYPE html><title>Content of a.html.</title>' > a.html
Run:
nc -l localhost 8000
Open the HTML on your browser, select the files and click on submit and check the terminal.
nc

Just before I go into detail about how you can access the state of a child component, please make sure to read Markus-ipse's answer regarding a better solution to handle this particular scenario.
If you do indeed wish to access the state of a component's children, you can assign a property called ref
to each child. There are now two ways to implement references: Using React.createRef()
and callback refs.
React.createRef()
This is currently the recommended way to use references as of React 16.3 (See the docs for more info). If you're using an earlier version then see below regarding callback references.
You'll need to create a new reference in the constructor of your parent component and then assign it to a child via the ref
attribute.
class FormEditor extends React.Component {
constructor(props) {
super(props);
this.FieldEditor1 = React.createRef();
}
render() {
return <FieldEditor ref={this.FieldEditor1} />;
}
}
In order to access this kind of ref, you'll need to use:
const currentFieldEditor1 = this.FieldEditor1.current;
This will return an instance of the mounted component so you can then use currentFieldEditor1.state
to access the state.
Just a quick note to say that if you use these references on a DOM node instead of a component (e.g. <div ref={this.divRef} />
) then this.divRef.current
will return the underlying DOM element instead of a component instance.
This property takes a callback function that is passed a reference to the attached component. This callback is executed immediately after the component is mounted or unmounted.
For example:
<FieldEditor
ref={(fieldEditor1) => {this.fieldEditor1 = fieldEditor1;}
{...props}
/>
In these examples the reference is stored on the parent component. To call this component in your code, you can use:
this.fieldEditor1
and then use this.fieldEditor1.state
to get the state.
One thing to note, make sure your child component has rendered before you try to access it ^_^
As above, if you use these references on a DOM node instead of a component (e.g. <div ref={(divRef) => {this.myDiv = divRef;}} />
) then this.divRef
will return the underlying DOM element instead of a component instance.
If you want to read more about React's ref property, check out this page from Facebook.
Make sure you read the "Don't Overuse Refs" section that says that you shouldn't use the child's state
to "make things happen".
Hope this helps ^_^
Edit: Added React.createRef()
method for creating refs. Removed ES5 code.
Have you ever tried to require
a module? What were the results? Just try:
MyModule = Module.new
require MyModule # see what happens
Modules cannot be required, only included!
In the early days of SQL, it was chosen as the solution to the problem of how to deal with duplicate column names (see below note).
To borrow a query from another answer:
SELECT P.ProductName,
P.ProductRetailPrice,
O.Quantity
FROM Products AS P
INNER JOIN Orders AS O ON O.ProductID = P.ProductID
WHERE O.OrderID = 123456
The column ProductID
(and possibly others) is common to both tables and since the join condition syntax requires reference to both, the 'dot qualification' provides disambiguation.
Of course, the better solution was to never have allowed duplicate column names in the first place! Happily, if you use the newer NATURAL JOIN
syntax, the need for the range variables P
and O
goes away:
SELECT ProductName, ProductRetailPrice, Quantity
FROM Products NATURAL JOIN Orders
WHERE OrderID = 123456
But why is the AS
keyword optional? My recollection from a personal discussion with a member of the SQL standard committee (either Joe Celko or Hugh Darwen) was that their recollection was that, at the time of defining the standard, one vendor's product (Microsoft's?) required its inclusion and another vendor's product (Oracle's?) required its omission, so the compromise chosen was to make it optional. I have no citation for this, you either believe me or not!
In the early days of the relational model, the cross product (or theta-join or equi-join) of relations whose headings are not disjoint appeared to produce a relation with two attributes of the same name; Codd's solution to this problem in his relational calculus was the use of dot qualification, which was later emulated in SQL (it was later realised that so-called natural join was primitive without loss; that is, natural join can replace all theta-joins and even cross product.)
I guess this is what you want, it does exactly what you specified.
#include<stdio.h>
#include<stdlib.h>
int main(int argc, char** argv) {
int age;
char* buffer;
buffer = malloc(200 * sizeof(char));
sscanf("19 cool kid", "%d cool %s", &age, buffer);
printf("cool %s is %d years old\n", buffer, age);
return 0;
}
The format expects: first a number (and puts it at where &age points to), then whitespace (zero or more), then the literal string "cool", then whitespace (zero or more) again, and then finally a string (and put that at whatever buffer points to). You forgot the "cool" part in your format string, so the format then just assumes that is the string you were wanting to assign to buffer. But you don't want to assign that string, only skip it.
Alternative, you could also have a format string like: "%d %s %s", but then you must assign another buffer for it (with a different name), and print it as: "%s %s is %d years old\n".
$data = $this->db->get_where('columnname',array('code' => 'B'));
$this->db->where_in('columnname',$data);
$this->db->where('code !=','B');
$query = $this->db->get();
return $query->result_array();
On top of what the others have already stated, some sort of server-side scripting is necessary in order for the server to read and save the file.
Using PHP might be a good choice, but you're free to use any server-side scripting language. http://www.w3schools.com/php/php_file_upload.asp may be of use on that end.
I know this is old and there are several good solutions already posted, but a simple solution that worked for me is the following CSS
<style>
.divider{
margin: 0cm 0cm .5cm 0cm;
}
</style>
and then create a div in your html
<div class="divider"></div>
Life is simple if you get a good web framework. Web services in Django are easy. Define your model, write view functions that return your CSV documents. Skip the templates.
This is not what you exactly want but for sure will help you out
I'm surprised there's not more information out there about component communication <=> consider this tutorial by angualr2
For sibling components communication, I'd suggest to go with sharedService
. There are also other options available though.
import {Component,bind} from 'angular2/core';
import {bootstrap} from 'angular2/platform/browser';
import {HTTP_PROVIDERS} from 'angular2/http';
import {NameService} from 'src/nameService';
import {TheContent} from 'src/content';
import {Navbar} from 'src/nav';
@Component({
selector: 'app',
directives: [TheContent,Navbar],
providers: [NameService],
template: '<navbar></navbar><thecontent></thecontent>'
})
export class App {
constructor() {
console.log('App started');
}
}
bootstrap(App,[]);
Please refer to link at top for more code.
Edit: This is a very small demo. You have already mention that you have already tried with sharedService
. So please consider this tutorial by angualr2 for more information.

These are the two options I managed to build, not having the luxury of working with var
type, nor with additional variables on the line:
string f = "aS.".Substring(0, "aS.".IndexOf("S"));
Console.WriteLine(f);
string s = "aS.".Split("S".ToCharArray(),StringSplitOptions.RemoveEmptyEntries)[0];
Console.WriteLine(s);
This is what it gets:
I strongly advocate for PostGis. It's specific for that kind of datatype and it has out of the box methods to calculate distance between points, among other GIS operations that you can find useful in the future
If you want to move from c:\

, write on console: c:\Documents\[space]+tab
and cygwin will autocomplete it as c:\Documents\ and\ settings/
you could use display: inline-block;
hope it is useful.

If you don't want manually set each field.
You can override any built-in function by just re-declaring it.
parseFloat = function(a){
alert(a)

Now parseFloat(3)
will alert 3.
Here is a generic function for it. Keep the RNG creation outside the high frequency code.
public static Random RNG = new Random();
public static T RandomEnum<T>()
{
Type type = typeof(T);
Array values = Enum.GetValues(type);
lock(RNG)
{
object value= values.GetValue(RNG.Next(values.Length));
return (T)Convert.ChangeType(value, type);
}
}
Usage example:
System.Windows.Forms.Keys randomKey = RandomEnum<System.Windows.Forms.Keys>();
Just assign it to it's own first element:
$array = $array[0];
Firebug + console.log(myObjectInstance)

Revised Answer
If you're not calling this code from another program, an option is to skip PL/SQL and do it strictly in SQL using bind variables:
var myname varchar2(20);
exec :myname := 'Tom';
SELECT *
FROM Customers
WHERE Name = :myname;
In many tools (such as Toad and SQL Developer), omitting the var
and exec
statements will cause the program to prompt you for the value.
Original Answer
A big difference between T-SQL and PL/SQL is that Oracle doesn't let you implicitly return the result of a query. The result always has to be explicitly returned in some fashion. The simplest way is to use DBMS_OUTPUT
(roughly equivalent to print
) to output the variable:
DECLARE
myname varchar2(20);
BEGIN
myname := 'Tom';
dbms_output.print_line(myname);
END;
This isn't terribly helpful if you're trying to return a result set, however. In that case, you'll either want to return a collection or a refcursor. However, using either of those solutions would require wrapping your code in a function or procedure and running the function/procedure from something that's capable of consuming the results. A function that worked in this way might look something like this:
CREATE FUNCTION my_function (myname in varchar2)
my_refcursor out sys_refcursor
BEGIN
open my_refcursor for
SELECT *
FROM Customers
WHERE Name = myname;
return my_refcursor;
END my_function;
It's not officially supported yet.
Edit: It's now supported in modern versions of Android Studio, at least on some platforms.
If you're using an old version of Android Studio which doesn't support the Google Play Store, and you refuse to upgrade, here are two possible workarounds:
Ask your favorite app's maintainers to upload a copy of their app into the Amazon Appstore. Next, install the Appstore onto your Android device. Finally, use the Appstore to install your favorite app.
Or: Do a Web search to find a .apk file for the software you want. For example, if you want to install SleepBot in your Android emulator, you can do a Google Web search for [ SleepBot apk
]. Then use adb install
to install the .apk file.
I wanted to do this with a Google Maps API custom overlay. Their sample code simply uses JS to insert IMG elements and the image placeholder box is displayed until the image is loaded. I found an answer here that worked for me : https://stackoverflow.com/a/10863680/2095698 .
$('<img src="'+ imgPaht +'">').load(function() {
$(this).width(some).height(some).appendTo('#some_target');
});
This preloads an image as suggested before, and then uses the handler to append the img object after the img URL is loaded. jQuery's documentation warns that cached images don't work well with this eventing/handler code, but it's working for me in FireFox and Chrome, and I don't have to worry about IE.

To achieve this use following html:

<script>
function make(e) {
// ... your function code
// e.preventDefault(); // use this to NOT go to href site
}
</script>
Here is working example.
function GetDirectorySize($path){
$bytestotal = 0;
$path = realpath($path);
if($path!==false && $path!='' && file_exists($path)){
foreach(new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path, FilesystemIterator::SKIP_DOTS)) as $object){
$bytestotal += $object->getSize();
}
}
return $bytestotal;
}
The same idea as Janith Chinthana suggested. With a few fixes:
$path
to realpath.
and ..
filesDon't use exceptions for flow control. Use DateTime.TryParse and DateTime.TryParseExact. Personally I prefer TryParseExact with a specific format, but I guess there are times when TryParse is better. Example use based on your original code:
DateTime value;
if (!DateTime.TryParse(startDateTextBox.Text, out value))
{
startDateTextox.Text = DateTime.Today.ToShortDateString();
}
Reasons for preferring this approach:
One way is to just leave merged feature branches open (and inactive):
$ hg up default
$ hg merge feature-x
$ hg ci -m merge
$ hg heads
(1 head)
$ hg branches
default 43:...
feature-x 41:...
(2 branches)
$ hg branches -a
default 43:...
(1 branch)
Another way is to close a feature branch before merging using an extra commit:
$ hg up feature-x
$ hg ci -m 'Closed branch feature-x' --close-branch
$ hg up default
$ hg merge feature-x
$ hg ci -m merge
$ hg heads
(1 head)
$ hg branches
default 43:...
(1 branch)
The first one is simpler, but it leaves an open branch. The second one leaves no open heads/branches, but it requires one more auxiliary commit. One may combine the last actual commit to the feature branch with this extra commit using --close-branch
, but one should know in advance which commit will be the last one.
Update: Since Mercurial 1.5 you can close the branch at any time so it will not appear in both hg branches
and hg heads
anymore. The only thing that could possibly annoy you is that technically the revision graph will still have one more revision without childen.
Update 2: Since Mercurial 1.8 bookmarks have become a core feature of Mercurial. Bookmarks are more convenient for branching than named branches. See also this question:
Since it takes 2 mins to respond, you can increase the timeout to 3 mins by adding the below code
scGetruntotals.CommandTimeout = 180;
Note : the parameter value is in seconds.
if you are on ubuntu u can try these commands:
sudo apt install npm
npm install && npm run dev
public void run() {
byte[] buffer = new byte[256];
int bytes;
while (true) {
try {
bytes = mmInStream.read(buffer);
mHandler.obtainMessage(RECIEVE_MESSAGE, bytes, -1, buffer).sendToTarget();
} catch (IOException e) {
break;
}
}
}
It would make for a handy function. Also, note I'm using STUFF instead of SUBSTRING.
create function str2uniq(@s varchar(50)) returns uniqueidentifier as begin
-- just in case it came in with 0x prefix or dashes...
set @s = replace(replace(@s,'0x',''),'-','')
-- inject dashes in the right places
set @s = stuff(stuff(stuff(stuff(@s,21,0,'-'),17,0,'-'),13,0,'-'),9,0,'-')
return cast(@s as uniqueidentifier)
end
Have you tried actually adding the Access-Control-Allow-Origin header to the response sent from your server? Like, Access-Control-Allow-Origin: *
?
Perhaps use plt.annotate:
import numpy as np
import matplotlib.pyplot as plt
N = 10
data = np.random.random((N, 4))
labels = ['point{0}'.format(i) for i in range(N)]
plt.subplots_adjust(bottom = 0.1)
plt.scatter(
data[:, 0], data[:, 1], marker='o', c=data[:, 2], s=data[:, 3] * 1500,
cmap=plt.get_cmap('Spectral'))
for label, x, y in zip(labels, data[:, 0], data[:, 1]):
plt.annotate(
label,
xy=(x, y), xytext=(-20, 20),
textcoords='offset points', ha='right', va='bottom',
bbox=dict(boxstyle='round,pad=0.5', fc='yellow', alpha=0.5),
arrowprops=dict(arrowstyle = '->', connectionstyle='arc3,rad=0'))
plt.show()
Try this; bear in mind that JavaScript months are 0-indexed, whilst days are 1-indexed.
var date = new Date('2010-10-11T00:00:00+05:30');_x000D_
alert(((date.getMonth() > 8) ? (date.getMonth() + 1) : ('0' + (date.getMonth() + 1))) + '/' + ((date.getDate() > 9) ? date.getDate() : ('0' + date.getDate())) + '/' + date.getFullYear());

user225312's answer is correct:
A. To count number of characters in str
object, you can use len()
function:
>>> print(len('please anwser my question'))
25
B. To get memory size in bytes allocated to store str
object, you can use sys.getsizeof()
function
>>> from sys import getsizeof
>>> print(getsizeof('please anwser my question'))
50
It gets complicated for Python 2.
A. The len()
function in Python 2 returns count of bytes allocated to store encoded characters in a str
object.
Sometimes it will be equal to character count:
>>> print(len('abc'))
3
But sometimes, it won't:
>>> print(len('???')) # String contains Cyrillic symbols
6
That's because str
can use variable-length encoding internally. So, to count characters in str
you should know which encoding your str
object is using. Then you can convert it to unicode
object and get character count:
>>> print(len('???'.decode('utf8'))) #String contains Cyrillic symbols
3
B. The sys.getsizeof()
function does the same thing as in Python 3 - it returns count of bytes allocated to store the whole string object
>>> print(getsizeof('???'))
27
>>> print(getsizeof('???'.decode('utf8')))
32
You were on the right track with response.getOutputStream()
, but you're not using its output anywhere in your code. Essentially what you need to do is to stream the PDF file's bytes directly to the output stream and flush the response. In Spring you can do it like this:
@RequestMapping(value="/getpdf", method=RequestMethod.POST)
public ResponseEntity<byte[]> getPDF(@RequestBody String json) {
// convert JSON to Employee
Employee emp = convertSomehow(json);
// generate the file
PdfUtil.showHelp(emp);
// retrieve contents of "C:/tmp/report.pdf" that were written in showHelp
byte[] contents = (...);
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_PDF);
// Here you have to set the actual filename of your pdf
String filename = "output.pdf";
headers.setContentDispositionFormData(filename, filename);
headers.setCacheControl("must-revalidate, post-check=0, pre-check=0");
ResponseEntity<byte[]> response = new ResponseEntity<>(contents, headers, HttpStatus.OK);
return response;
}
Notes:
showHelp
is not a good ideabyte[]
: example hereshowHelp()
to avoid overwriting the file if two users send a request at the same time<div id="ABLAHALAHOO">8008</div>
<div id="WABOOLAWADO">1110</div>
parseInt( $( '#ABLAHALAHOO' ).text()) > parseInt( $( '#WABOOLAWADO ).text()) ? alert( 'Eat potato' ) : alert( 'You starve' );
The only solution here that worked for me in 5.6.5 was bigstone1998's regex answer. I'd prefer not to use a regex search though for performance reasons. I believe the reason the other solutions don't work is because a standard field will be analyzed and as a result have no empty string token to negate against. The exists query won't help on it's own either since an empty string is considered non-null.
If you can't change the index the regex approach may be your only option, but if you can change the index then adding a keyword subfield will solve the problem.
In the mappings for the index:
"myfield": {
"type": "text",
"fields": {
"keyword": {
"ignore_above": 256,
"type": "keyword"
}
}
}
Then you can simply use the query:
{
"query": {
"bool": {
"must": {
"exists": {
"field": "myfield"
}
},
"must_not": {
"term": {
"myfield.keyword": ""
}
}
}
}
}
Note the .keyword
in the must_not component.
You should not place an using
directive in an header file, it creates unnecessary headaches.
Also you need an include guard in your header.
EDIT: of course, after having fixed the include guard issue, you also need a complete declaration of student in the header file. As pointed out by others the forward declaration is not sufficient in your case.
One Line:
ALTER TABLE `user_customer_permission` DROP PRIMARY KEY , ADD PRIMARY KEY ( `id` )
You will also not lose the auto-increment and have to re-add it which could have side-effects.
It will delete a folder recursively
public static void folderdel(String path){
File f= new File(path);
if(f.exists()){
String[] list= f.list();
if(list.length==0){
if(f.delete()){
System.out.println("folder deleted");
return;
}
}
else {
for(int i=0; i<list.length ;i++){
File f1= new File(path+"\\"+list[i]);
if(f1.isFile()&& f1.exists()){
f1.delete();
}
if(f1.isDirectory()){
folderdel(""+f1);
}
}
folderdel(path);
}
}
}
You have to give the values between 0 and 1.0. So divide the RGB values by 255.
myLabel.textColor= [UIColor colorWithRed:(160/255.0) green:(97/255.0) blue:(5/255.0) alpha:1] ;
Update:
You can also use this macro
#define Rgb2UIColor(r, g, b) [UIColor colorWithRed:((r) / 255.0) green:((g) / 255.0) blue:((b) / 255.0) alpha:1.0]
and you can call in any of your class like this
myLabel.textColor = Rgb2UIColor(160, 97, 5);
This is the normal color synax
myLabel.textColor = UIColor(red: (160/255.0), green: (97/255.0), blue: (5/255.0), alpha: 1.0)
//The values should be between 0 to 1
Swift is not much friendly with macros
Complex macros are used in C and Objective-C but have no counterpart in Swift. Complex macros are macros that do not define constants, including parenthesized, function-like macros. You use complex macros in C and Objective-C to avoid type-checking constraints or to avoid retyping large amounts of boilerplate code. However, macros can make debugging and refactoring difficult. In Swift, you can use functions and generics to achieve the same results without any compromises. Therefore, the complex macros that are in C and Objective-C source files are not made available to your Swift code.
So we use extension for this
extension UIColor {
convenience init(_ r: Double,_ g: Double,_ b: Double,_ a: Double) {
self.init(red: r/255, green: g/255, blue: b/255, alpha: a)
}
}
You can use it like
myLabel.textColor = UIColor(160.0, 97.0, 5.0, 1.0)
Sometimes the value needs to be trimmed of whitespace or it won't be matched, in such case this additional step can be used (source):
if(((DropDownList) myControl1).Items.Cast<ListItem>().Select(i => i.Value.Trim() == ctrl.value.Trim()).FirstOrDefault() != null){}
Using Guava's ByteStreams.copy()
:
ByteStreams.copy(inputStream, outputStream);
Try this solution.
$mainModelData = mainModel::where('column', $value)
->join('relationModal', 'main_table_name.relation_table_column', '=', 'relation_table.id')
->orderBy('relation_table.title', 'ASC')
->with(['relationModal' => function ($q) {
$q->where('column', 'value');
}])->get();
Example:
$user = User::where('city', 'kullu')
->join('salaries', 'users.id', '=', 'salaries.user_id')
->orderBy('salaries.amount', 'ASC')
->with(['salaries' => function ($q) {
$q->where('amount', '>', '500000');
}])->get();
You can change the column name in join()
as per your database structure.

Happy Knowledge Sharing
Python for whatever reason does not come with a built-in way to have natural sorting (meaning 1, 2, 10 instead of 1, 10, 2), so you have to write it yourself:
import re
def sorted_alphanumeric(data):
convert = lambda text: int(text) if text.isdigit() else text.lower()
alphanum_key = lambda key: [ convert(c) for c in re.split('([0-9]+)', key) ]
return sorted(data, key=alphanum_key)
You can now use this function to sort a list:
dirlist = sorted_alphanumeric(os.listdir(...))
PROBLEMS:
In case you use the above function to sort strings (for example folder names) and want them sorted like Windows Explorer does, it will not work properly in some edge cases.
This sorting function will return incorrect results on Windows, if you have folder names with certain 'special' characters in them. For example this function will sort 1, !1, !a, a
, whereas Windows Explorer would sort !1, 1, !a, a
.
So if you want to sort exactly like Windows Explorer does in Python you have to use the Windows built-in function StrCmpLogicalW via ctypes (this of course won't work on Unix):
from ctypes import wintypes, windll
from functools import cmp_to_key
def winsort(data):
_StrCmpLogicalW = windll.Shlwapi.StrCmpLogicalW
_StrCmpLogicalW.argtypes = [wintypes.LPWSTR, wintypes.LPWSTR]
_StrCmpLogicalW.restype = wintypes.INT
cmp_fnc = lambda psz1, psz2: _StrCmpLogicalW(psz1, psz2)
return sorted(data, key=cmp_to_key(cmp_fnc))
This function is slightly slower than sorted_alphanumeric()
.
Bonus: winsort
can also sort full paths on Windows.
Alternatively, especially if you use Unix, you can use the natsort
library (pip install natsort
) to sort by full paths in a correct way (meaning subfolders at the correct position).
You can use it like this to sort full paths:
from natsort import natsorted, ns
dirlist = natsorted(dirlist, alg=ns.PATH | ns.IGNORECASE)
Starting with version 7.1.0 natsort supports os_sorted
which internally uses either the beforementioned Windows API or Linux sorting and should be used instead of natsorted()
.

Try disable proguard, if it manage to compile without issue then you will need to figure out which library caused it and add it to proguard-rules.pro
file
In my case this issue occur when I updated compile 'com.google.android.gms:play-services-ads:8.3.0'
to compile 'com.google.android.gms:play-services-ads:8.4.0'
One of the workaround is I added this to proguard-rules.pro
file
## Google AdMob specific rules ##
## https://developers.google.com/admob/android/quick-start ##
-keep public class com.google.ads.** {

}
choices = {'key1':'val1', 'key2':'val2'}
Here's the template:
<ul>
{% for key, value in choices.items %}
<li>{{key}} - {{value}}</li>
{% endfor %}
</ul>
Basically, .items
is a Django keyword that splits a dictionary into a list of (key, value)
pairs, much like the Python method .items()
. This enables iteration over a dictionary in a Django template.
I have not tested this, but a multi statement function caches the result set. There may be cases where there is too much going on for the optimizer to inline the function. For example suppose you have a function that returns a result from different databases depending on what you pass as a "Company Number". Normally, you could create a view with a union all then filter by company number but I found that sometimes sql server pulls back the entire union and is not smart enough to call the one select. A table function can have logic to choose the source.
To add to tacaswell's answer, the colorbar()
function has an optional cax
input you can use to pass an axis on which the colorbar should be drawn. If you are using that input, you can directly set a label using that axis.
import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable
fig, ax = plt.subplots()
heatmap = ax.imshow(data)
divider = make_axes_locatable(ax)
cax = divider.append_axes('bottom', size='10%', pad=0.6)
cb = fig.colorbar(heatmap, cax=cax, orientation='horizontal')
cax.set_xlabel('data label') # cax == cb.ax
a=[1,2,3]
b=[str(x) for x in a]
print b
above method is the easiest and most general way to convert list into string. another short method is-
a=[1,2,3]
b=map(str,a)
print b

Actually, the jQuery documentation has a more simple approach than the chained examples shown above (although they'll work just fine):
$("#myElement").unbind('mouseenter mouseleave');
As of jQuery 1.7, you are also able use $.on()
and $.off()
for event binding, so to unbind the hover event, you would use the simpler and tidier:
$('#myElement').off('hover');
The pseudo-event-name "hover" is used as a shorthand for "mouseenter mouseleave" but was handled differently in earlier jQuery versions; requiring you to expressly remove each of the literal event names. Using $.off()
now allows you to drop both mouse events using the same shorthand.
Edit 2016:
Still a popular question so it's worth drawing attention to @Dennis98's point in the comments below that in jQuery 1.9+, the "hover" event was deprecated in favour of the standard "mouseenter mouseleave" calls. So your event binding declaration should now look like this:
$('#myElement').off('mouseenter mouseleave');
if your requirement is like parsing an replacing multiple variable and then use it as a hash/or anything then you can do something like this
require 'yaml'
require 'json'
yaml = YAML.load_file("xxxx.yaml")
blueprint = yaml.to_json % { var_a: "xxxx", var_b: "xxxx"}
hash = JSON.parse(blueprint)
inside the yaml just put variables like this
"%{var_a}"
UPDATE: As Joel Coehoorn and others suggest, starting at .NET Framework 4.0, you can just check Environment.Is64BitOperatingSystem
.
IntPtr.Size won't return the correct value if running in 32-bit .NET Framework 2.0 on 64-bit Windows (it would return 32-bit).
As Microsoft's Raymond Chen describes, you have to first check if running in a 64-bit process (I think in .NET you can do so by checking IntPtr.Size), and if you are running in a 32-bit process, you still have to call the Win API function IsWow64Process. If this returns true, you are running in a 32-bit process on 64-bit Windows.
Microsoft's Raymond Chen: How to detect programmatically whether you are running on 64-bit Windows
My solution:
static bool is64BitProcess = (IntPtr.Size == 8);
static bool is64BitOperatingSystem = is64BitProcess || InternalCheckIsWow64();
[DllImport("kernel32.dll", SetLastError = true, CallingConvention = CallingConvention.Winapi)]
[return: MarshalAs(UnmanagedType.Bool)]
private static extern bool IsWow64Process(
[In] IntPtr hProcess,
[Out] out bool wow64Process
);
public static bool InternalCheckIsWow64()
{
if ((Environment.OSVersion.Version.Major == 5 && Environment.OSVersion.Version.Minor >= 1) ||
Environment.OSVersion.Version.Major >= 6)
{
using (Process p = Process.GetCurrentProcess())
{
bool retVal;
if (!IsWow64Process(p.Handle, out retVal))
{
return false;
}
return retVal;
}
}
else
{
return false;
}
}
This issue is probably because of the earlier versions of Java installed in your System. First check your Environment Variables Carefully and remove all the Environment Variables related to the previous versions of JAVA and replace those paths to
C:\Program Files\Java\<your new jdk version>\bin
This is solved for me when I update maven and check the option "Force update of Snapshots/Releases" in Eclipse. this clears all errors. So right click on project -> Maven -> update project, then check the above option -> Ok. Hope this helps you.

If you want to right-align in a form, you can try:
| Option | Description |
| ------:| -----------:|
| data | path to data files to supply the data that will be passed into templates. |
| engine | engine to be used for processing templates. Handlebars is the default. |
| ext | extension to be used for dest files. |

The debugger is making it simpler, because you don't want to step through the actual code that the compiler creates.
If the switch contains more than five items, it's implemented using a lookup table or hash table, otherwise it's implemeneted using an if..else.
See the closely related question is “else if” faster than “switch() case” ?.
Other languages than C# will of course implement it more or less differently, but a switch is generally more efficient.

The problem is that readlines
is a list of strings, each of which is a line of filename
. Perhaps you meant:
for line in readlines:
Type = line.split(",")
x = Type[1]
y = Type[2]
print(x,y)
Here you have not specified class name to be imported from Map.js file. If Map is class exportable class name exist in the Map.js file, your code should be as follow.
import React, { Component } from 'react';
import Map from './Map';
class App extends Component {
render() {
return (
<div className="App">
<Map/>
</div>
);
}
}
export default App;
Here's the GNU version of printf
... you can see it passing in stdout
to vfprintf
:
__printf (const char *format, ...)
{
va_list arg;
int done;
va_start (arg, format);
done = vfprintf (stdout, format, arg);
va_end (arg);
return done;
}
Here's a link to vfprintf
... all the formatting 'magic' happens here.
The only thing that's truly 'different' about these functions is that they use varargs to get at arguments in a variable length argument list. Other than that, they're just traditional C. (This is in contrast to Pascal's printf
equivalent, which is implemented with specific support in the compiler... at least it was back in the day.)
If you want to do this in jQuery instead of CSS, you basically follow the same process.
Assuming you have some <div id="target"></div>
, you can use the following code:
$("#target").hover(function() {
$(this).css('cursor','pointer');
}, function() {
$(this).css('cursor','auto');
});
and that should do it.
