You could try a for loop
for func,args,kwargs in zip([a,b,c,d],
[args_a,args_b,args_c,args_d],
[kw_a,kw_b,kw_c,kw_d]):
try:
func(*args, **kwargs)
break
except:
pass
This way you can loop as many functions as you want without making the code look ugly
There are some cases where you can use the e.message or e.messages.. But it does not work in all cases. Anyway the more safe is to use the str(e)
try:
...
except Exception as e:
print(e.message)
Building up on Yoav's answer, an even safer approach:
def deep_get(dictionary, *keys):
return reduce(lambda d, key: d.get(key, None) if isinstance(d, dict) else None, keys, dictionary)
If you don't want to handle error just NoneType
and use get()
e.g.:
manager.connect.get("")
In short: this happens likely when you are hot-deploying webapps. For instance, your ide+development server hot-deploys a war again. Threads, that have been created previously are still running. But meanwhile their classloader/context is invalid and faces the IllegalAccessException / IllegalStateException becouse its orgininating webapp (the former runtime-environment) has been redeployed.
So, as states here, a restart does not permanently resolve this issue. Instead, it is better to find/implement a managed Thread Pool, s.th. like this to handle the termination of threads appropriately. In JavaEE you will use these ManagedThreadExeuctorServices. A similar opinion and reference here.
Examples for this are the EvictorThread of Apache Commons Pool, that "cleans" pooled instances according to the pool's configuration (max idle etc.).

I would strongly recommend field access and NOT annotations on the getters (property access) if you want to do anything more in the setters than just setting the value (e.g. Encryption or calculation).
The problem with the property access is that the setters are also called when the object is loaded. This has worked for me fine for many month until we wanted to introduce encryption. In our use case we wanted to encrypt a field in the setter and decrypt it in the getter. The problem now with property access was that when Hibernate loaded the object it was also calling the setter to populate the field and thus was encrypting the encrypted value again. This post also mentions this: Java Hibernate: Different property set function behavior depending on who is calling it
This has cause me headaches until I remembered the difference between field access and property access. Now I have moved all my annotations from property access to field access and it works fine now.
A simple solution by leveraging language's dynamic type checking:
function isNumber (string) {
//it has whitespace
if(string.trim() === ''){
return false
}
return string - 0 === string * 1
}
see test cases below
function isNumber (str) {
if(str.trim() === ''){
return false
}
return str - 0 === str * 1
}
console.log('-1' + ' ? ' + isNumber ('-1'))
console.log('-1.5' + ' ? ' + isNumber ('-1.5'))
console.log('0' + ' ? ' + isNumber ('0'))
console.log(', ,' + ' ? ' + isNumber (', ,'))
console.log('0.42' + ' ? ' + isNumber ('0.42'))
console.log('.42' + ' ? ' + isNumber ('.42'))
console.log('#abcdef' + ' ? ' + isNumber ('#abcdef'))
console.log('1.2.3' + ' ? ' + isNumber ('1.2.3'))
console.log('' + ' ? ' + isNumber (''))
console.log('blah' + ' ? ' + isNumber ('blah'))

Here is a solution for n-calls (recursive function). https://jsfiddle.net/mathew11/5f3mu0f4/7/
function myFunction(array){
var r = $.Deferred();
if(array.length == 0){
r.resolve();
return r;
}
var element = array.shift();
// async task
timer = setTimeout(function(){
$("a").text($("a").text()+ " " + element);
var resolving = function(){
r.resolve();
}
myFunction(array).done(resolving);
}, 500);
return r;
}
//Starting the function
var myArray = ["Hi", "that's", "just", "a", "test"];
var alerting = function (){window.alert("finished!")};
myFunction(myArray).done(alerting);
You don't say if this is a desktop or web app. I would use the getResourceAsStream()
method from an appropriate ClassLoader if it's a desktop or the Context if it's a web app.
You might want to do this.
input[type=checkbox] {
-ms-transform: scale(2); /* IE */
-moz-transform: scale(2); /* FF */
-webkit-transform: scale(2); /* Safari and Chrome */
-o-transform: scale(2); /* Opera */
padding: 10px;
}
A simple function using preg_match in php
<?php
function name_validation($name) {
if (!preg_match("/^[a-zA-Z ]*$/", $name) === false) {
echo "$name is a valid name";
} else {
echo "$name is not a valid name";
}
}
//Test
name_validation('89name');
?>
You cannot do it because you are already looping on it.
Inorder to avoid this situation use Iterator,which guarentees you to remove the element from list safely ...
List<Object> objs;
Iterator<Object> i = objs.iterator();
while (i.hasNext()) {
Object o = i.next();
//some condition
i.remove();
}
Buttons can be added to frozen rows as images. Assigning a function within the attached script to the button makes it possible to run the function. The comment which says you can not is of course a very old comment, possibly things have changed now.
I end up with this solutions. As we tap back button viewDidDisappear method called. we can check by calling isMovingFromParentViewController selector which return true. we can pass data back (Using Delegate).hope this help someone.
-(void)viewDidDisappear:(BOOL)animated{
if (self.isMovingToParentViewController) {
}
if (self.isMovingFromParentViewController) {
//moving back
//pass to viewCollection delegate and update UI
[self.delegateObject passBackSavedData:self.dataModel];
}
}
You can use this code
<script>
// Replace the <textarea id="editor"> with a CKEditor
// instance, using default configuration.
CKEDITOR.config.filebrowserImageBrowseUrl = '/admin/laravel-filemanager?type=Files';
CKEDITOR.config.filebrowserImageUploadUrl = '/admin/laravel-filemanager/upload?type=Images&_token=';
CKEDITOR.config.filebrowserBrowseUrl = '/admin/laravel-filemanager?type=Files';
CKEDITOR.config.filebrowserUploadUrl = '/admin/laravel-filemanager/upload?type=Files&_token=';
CKEDITOR.replaceAll( 'editor');
</script>
If you use Shouldly, you can use ShouldAllBe with Contains.
collection1 = {1, 2, 3, 4};
collection2 = {2, 4, 1, 3};
collection1.ShouldAllBe(item=>collection2.Contains(item)); // true
And finally, you can write an extension.
public static class ShouldlyIEnumerableExtensions
{
public static void ShouldEquivalentTo<T>(this IEnumerable<T> list, IEnumerable<T> equivalent)
{
list.ShouldAllBe(l => equivalent.Contains(l));
}
}
UPDATE
A optional parameter exists on ShouldBe method.
collection1.ShouldBe(collection2, ignoreOrder: true); // true
What solved the problem for me was - create a folder "drawable" in "..platforms/android/res/" and put "icon.png" in it.
I just wanted to add that "Include" is part of eager loading. It is described in Entity Framework 6 tutorial by Microsoft. Here is the link: https://docs.microsoft.com/en-us/aspnet/mvc/overview/getting-started/getting-started-with-ef-using-mvc/reading-related-data-with-the-entity-framework-in-an-asp-net-mvc-application
Excerpt from the linked page:
Here are several ways that the Entity Framework can load related data into the navigation properties of an entity:
Lazy loading. When the entity is first read, related data isn't retrieved. However, the first time you attempt to access a navigation property, the data required for that navigation property is automatically retrieved. This results in multiple queries sent to the database — one for the entity itself and one each time that related data for the entity must be retrieved. The DbContext class enables lazy loading by default.
Eager loading. When the entity is read, related data is retrieved along with it. This typically results in a single join query that retrieves all of the data that's needed. You specify eager loading by using the
Include
method.Explicit loading. This is similar to lazy loading, except that you explicitly retrieve the related data in code; it doesn't happen automatically when you access a navigation property. You load related data manually by getting the object state manager entry for an entity and calling the Collection.Load method for collections or the Reference.Load method for properties that hold a single entity. (In the following example, if you wanted to load the Administrator navigation property, you'd replace
Collection(x => x.Courses)
withReference(x => x.Administrator)
.) Typically you'd use explicit loading only when you've turned lazy loading off.Because they don't immediately retrieve the property values, lazy loading and explicit loading are also both known as deferred loading.
You can pass it as a normal prop: foo={<ComponentOne />}
For example:
const ComponentOne = () => <div>Hello world!</div>
const ComponentTwo = () => (
<div>
<div>Hola el mundo!</div>
<ComponentThree foo={<ComponentOne />} />
</div>
)
const ComponentThree = ({ foo }) => <div>{foo}</div>
<div class="container-fluid">
<div class="row">
<h3 class="one">Text</h3>
<button class="btn btn-secondary ml-auto">Button</button>
</div>
</div>
.ml-auto
is Bootstraph 4's non-flexbox way of aligning things.
The same problem can occur if you have downloaded JUnit jar from the JUnit website, but forgotten to download the Hamcrest jar - both are required (the instructions say to download both, but I skipped ahead! Oops)
I have a simple example here to display date and time with Millisecond......
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
public class MyClass{
public static void main(String[]args){
LocalDateTime myObj = LocalDateTime.now();
DateTimeFormatter myFormat = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS);
String forDate = myObj.format(myFormat);
System.out.println("The Date and Time are: " + forDate);
}
}
strtotime returns the current timestamp and date is to format timestamp
$date=strtotime(date("h:i:sa"))+900;//15*60=900 seconds
$date=date("h:i:sa",$date);
This will add 15 mins to the current time
For the given json format as in file ~/my-app/src/db/abc.json:
[
{
"name":"Ankit",
"id":1
},
{
"name":"Aditi",
"id":2
},
{
"name":"Avani",
"id":3
}
]
inorder to import to .js file like ~/my-app/src/app.js:
const json = require("./db/abc.json");
class Arena extends React.Component{
render(){
return(
json.map((user)=>
{
return(
<div>{user.name}</div>
)
}
)
}
);
}
}
export default Arena;
Output:
Ankit Aditi Avani
The main difference between Web server and application server is that web server is meant to serve static pages e.g. HTML and CSS, while Application Server is responsible for generating dynamic content by executing server side code e.g. JSP, Servlet or EJB.
Which one should i use?
Once you know the difference between web and application server and web containers, it's easy to figure out when to use them.
You need a web server
like Apache HTTPD if you are serving static web pages. If you have a Java application with just JSP and Servlet to generate dynamic content then you need web containers
like Tomcat or Jetty. While, if you have Java EE application using EJB, distributed transaction, messaging and other fancy features than you need a full fledged application server
like JBoss, WebSphere or Oracle's WebLogic.
Web container is a part of Web Server and the Web Server is a part of Application Server.
Web Server is composed of web container, while Application Server is composed of web container as well as EJB container.
The reason it is throwing that exception is because you have the argument rb
, which opens the file in binary mode. Change that to r
, which will by default open the file in text mode.
Your code:
import csv
ifile = open('sample.csv', "rb")
read = csv.reader(ifile)
for row in read :
print (row)
New code:
import csv
ifile = open('sample.csv', "r")
read = csv.reader(ifile)
for row in read :
print (row)
iPhone format strings are in Unicode format. Behind the link is a table explaining what all the letters above mean so you can build your own.
And of course don't forget to release your date formatters when you're done with them. The above code leaks format
, now
, and inFormat
.
It is worth mentioning here. You can respond to the multiple combinations (Exception error and exception.message).
I ran into a use case scenario when trying to cast control object in a datagrid, with either content as TextBox, TextBlock or CheckBox. In this case the returned Exception was the same, but the message varied.
try
{
//do something
}
catch (Exception ex) when (ex.Message.Equals("the_error_message1_here"))
{
//do whatever you like
}
catch (Exception ex) when (ex.Message.Equals("the_error_message2_here"))
{
//do whatever you like
}
One easy way is to drag and drop. It will copy files to /sdcard/Download. You can copy whole folders or multiple files. Make sure that "Enable Clipboard Sharing" is enabled. (under ...->Settings)
Personally i prefer the format function, allows you to simply change the date part very easily.
declare @format varchar(100) = 'yyyy/MM/dd'
select
format(the_date,@format),
sum(myfield)
from mytable
group by format(the_date,@format)
order by format(the_date,@format) desc;
How about this...?
TextReader tr = new StringReader("<Root>Content</Root>");
XDocument doc = XDocument.Load(tr);
Console.WriteLine(doc);
This was taken from the MSDN docs for XDocument.Load, found here...
If you wrote the console application you can make it hidden by default.
Create a new console app then then change the "Output Type" type to "Windows Application" (done in the project properties)
In case you need it as a Class, you can extend it with dict and use update method:
Class a(dict):
# some stuff
self.update(b)
A switch
statement can only be used for integral values, not for values of user-defined type. And even if it could, your input operation doesn't work, either.
You might want this:
#include <string>
#include <iostream>
std::string input;
if (!std::getline(std::cin, input)) { /* error, abort! */ }
if (input == "Option 1")
{
// ...
}
else if (input == "Option 2")
{
// ...
}
// etc.
In some use cases, 307 redirects might be abused by an attacker to learn the victim's credentials.
Further information can be found in section 3.1 of A Comprehensive Formal Security Analysis of OAuth 2.0.
The authors of the above paper suggest the following:
Fix. Contrary to the current wording in the OAuth standard, the exact method of the redirect is not an implementation detail but essential for the security of OAuth. In the HTTP standard (RFC 7231), only the 303 redirect is defined unambigiously to drop the body of an HTTP POST request. All other HTTP redirection status codes, including the most commonly used 302, leave the browser the option to preserve the POST request and the form data. In practice, browsers typically rewrite to a GET request, thereby dropping the form data, except for 307 redirects. Therefore, the OAuth standard should require 303 redirects for the steps mentioned above in order to fix this problem.
In case you have a multi-module project :
let us say your module structure is
root-module
-> a-module
-> b-module
and the test(testToRun) you are looking to run is in b-module, with full path : com.xyz.b.module.TestClass.testToRun
As here you are interested to run the test in b-module, so you should see the tasks available for b-module.
./gradlew :b-module:tasks
The above command will list all tasks in b-module with description. And in ideal case, you will have a task named test to run the unit tests in that module.
./gradlew :b-module:test
Now, you have reached the point for running all the tests in b-module, finally you can pass a parameter to the above task to run tests which matches the certain path pattern
./gradlew :b-module:test --tests "com.xyz.b.module.TestClass.testToRun"
Now, instead of this if you run
./gradlew test --tests "com.xyz.b.module.TestClass.testToRun"
It will run the test task for both module a and b, which might result in failure as there is nothing matching the above pattern in a-module.
Create the user with a password :
http://www.postgresql.org/docs/current/static/sql-createuser.html
CREATE USER name [ [ WITH ] option [ ... ] ]
where option can be:
SUPERUSER | NOSUPERUSER
| CREATEDB | NOCREATEDB
| CREATEROLE | NOCREATEROLE
| CREATEUSER | NOCREATEUSER
| INHERIT | NOINHERIT
| LOGIN | NOLOGIN
| REPLICATION | NOREPLICATION
| CONNECTION LIMIT connlimit
| [ ENCRYPTED | UNENCRYPTED ] PASSWORD 'password'
| VALID UNTIL 'timestamp'
| IN ROLE role_name [, ...]
| IN GROUP role_name [, ...]
| ROLE role_name [, ...]
| ADMIN role_name [, ...]
| USER role_name [, ...]
| SYSID uid
Then grant the user rights on a specific database :
http://www.postgresql.org/docs/current/static/sql-grant.html
Example :
grant all privileges on database db_name to someuser;
Based on the above post i tried this and this worked fine I wanted to use the value of Map B as keys for Map A:
<c:if test="${not empty activityCodeMap and not empty activityDescMap}">
<c:forEach var="valueMap" items="${auditMap}">
<tr>
<td class="activity_white"><c:out value="${activityCodeMap[valueMap.value.activityCode]}"/></td>
<td class="activity_white"><c:out value="${activityDescMap[valueMap.value.activityDescCode]}"/></td>
<td class="activity_white">${valueMap.value.dateTime}</td>
</tr>
</c:forEach>
</c:if>
elementFormDefault="qualified" is used to control the usage of namespaces in XML instance documents (.xml file), rather than namespaces in the schema document itself (.xsd file).
By specifying elementFormDefault="qualified" we enforce namespace declaration to be used in documents validated with this schema.
It is common practice to specify this value to declare that the elements should be qualified rather than unqualified. However, since attributeFormDefault="unqualified" is the default value, it doesn't need to be specified in the schema document, if one does not want to qualify the namespaces.
Keep in mind that SQL strings can not be larger than 4000 bytes, while Pl/SQL can have strings as large as 32767 bytes. see below for an example of inserting a large string via an anonymous block which I believe will do everything you need it to do.

I want to note that you can just make all the console writelines comment code, but i thought it would be nice for you to test it. If you display all these after each other you get the same list as waruna majuna

You can load an assembly using *Assembly.Load** methods. Using Activator.CreateInstance you can create new instances of the type you want. Keep in mind that you have to use the full type name of the class you want to load (for example Namespace.SubNamespace.ClassName). Using the method InvokeMember of the Type class you can invoke methods on the type.
Also, take into account that once loaded, an assembly cannot be unloaded until the whole AppDomain is unloaded too (this is basically a memory leak).
Yes, it's true. Why do you doubt the php faq on the function? :)
The result of running password_hash()
has has four parts:
So as you can see, the hash is a part of it.
Sure, you could have an additional salt for an added layer of security, but I honestly think that's overkill in a regular php application. The default bcrypt algorithm is good, and the optional blowfish one is arguably even better.
None of the answers above pointed out why you might not see some of your prints. This is also because here you are dealing with streams (I didn't know this) and stream has something called orientation. Let me cite something from this source:
Narrow and wide orientation
A newly opened stream has no orientation. The first call to any I/O function establishes the orientation.
A wide I/O function makes the stream wide-oriented, a narrow I/O function makes the stream narrow-oriented. Once set, the orientation can only be changed with freopen.
Narrow I/O functions cannot be called on a wide-oriented stream; wide I/O functions cannot be called on a narrow-oriented stream. Wide I/O functions convert between wide and multibyte characters as if by calling mbrtowc and wcrtomb. Unlike the multibyte character strings that are valid in a program, multibyte character sequences in the file may contain embedded nulls and do not have to begin or end in the initial shift state.
So once you use printf()
your orientation becomes narrow and from this point on you can't get anything out of wprintf()
and you realy don't. Unless you use freeopen()
which is intended to be used on files.
As it turns out you can use freeopen()
like this:
freopen(NULL, "w", stdout);
To make stream "not defined" again. Try this example:
#include <stdio.h>
#include <wchar.h>

wprintf(L"%ls\n", y); // Conversion specifier %s with length modifier %l is

// At this point curent orientation of the stream is wide and this is why folowing

printf("1\n"); // Print narrow string of characters with a narrow function
printf("%s\n", "2"); // Print narrow string of characters with a narrow function
printf("%ls\n",L"3"); // Print wide string of characters with a narrow function

You also can do this very easily with awk
, if you're willing to consider a different tool:
echo "UPPER" | awk '{print tolower($0)}'
var now = DateTime.Now;
var first = new DateTime(now.Year, now.Month, 1);
var last = first.AddMonths(1).AddDays(-1);
You could also use DateTime.DaysInMonth
method:
var last = new DateTime(now.Year, now.Month, DateTime.DaysInMonth(now.Year, now.Month));
char*
and char[]
are different types, but it's not immediately apparent in all cases. This is because arrays decay into pointers, meaning that if an expression of type char[]
is provided where one of type char*
is expected, the compiler automatically converts the array into a pointer to its first element.
Your example function printSomething
expects a pointer, so if you try to pass an array to it like this:
char s[10] = "hello";
printSomething(s);
The compiler pretends that you wrote this:
char s[10] = "hello";
printSomething(&s[0]);
The solution I've come up with is:
isinstance(y, (np.ndarray, np.generic) )
However, it's not 100% clear that all numpy types are guaranteed to be either np.ndarray
or np.generic
, and this probably isn't version robust.
For people with a similar question and find this post (like I did); you can do this even without lastrow if your dataset is formatted as a table.
Range("tablename[columnname]").Formula = "=G3&"",""&L3"
Making it a true one liner. Hope it helps someone!
I just found the solution, kind of answering to my own question in case anyone else stumbles upon it.

You wanted to change the layout at runtime on button click. But that is not possible and as it has been rightly stated above, you need to restart the activity. You will come across a similar problem when u plan on changing the theme based on user's selection but it will not reflect in runtime. You will have to restart the activity.
import pandas as pd
import numpy as np
print(pd.Series(name_of_array).value_counts())
if you want to delete the whole table, you must follow the next SQL instruction
Delete FROM TABLE Where PRIMARY_KEY_ is Not NULL;
You probably want something like this:
Collections.sort(students, new Comparator<Student>() {
public int compare(Student s1, Student s2) {
if(s1.getName() != null && s2.getName() != null && s1.getName().comareTo(s1.getName()) != 0) {
return s1.getName().compareTo(s2.getName());
} else {
return s1.getAge().compareTo(s2.getAge());
}
}
);
This sorts the students first by name. If a name is missing, or two students have the same name, they are sorted by their age.
Based on the work of Bas Brekelmans above, I have also created two derivations -> "input" dialogs that allow you to receive from the user both a text value and a boolean (TextBox and CheckBox):
public static class PromptForTextAndBoolean
{
public static string ShowDialog(string caption, string text, string boolStr)
{
Form prompt = new Form();
prompt.Width = 280;
prompt.Height = 160;
prompt.Text = caption;
Label textLabel = new Label() { Left = 16, Top = 20, Width = 240, Text = text };
TextBox textBox = new TextBox() { Left = 16, Top = 40, Width = 240, TabIndex = 0, TabStop = true };
CheckBox ckbx = new CheckBox() { Left = 16, Top = 60, Width = 240, Text = boolStr };
Button confirmation = new Button() { Text = "Okay!", Left = 16, Width = 80, Top = 88, TabIndex = 1, TabStop = true };
confirmation.Click += (sender, e) => { prompt.Close(); };
prompt.Controls.Add(textLabel);
prompt.Controls.Add(textBox);
prompt.Controls.Add(ckbx);
prompt.Controls.Add(confirmation);
prompt.AcceptButton = confirmation;
prompt.StartPosition = FormStartPosition.CenterScreen;
prompt.ShowDialog();
return string.Format("{0};{1}", textBox.Text, ckbx.Checked.ToString());
}
}
...and text along with a selection of one of multiple options (TextBox and ComboBox):
public static class PromptForTextAndSelection
{
public static string ShowDialog(string caption, string text, string selStr)
{
Form prompt = new Form();
prompt.Width = 280;
prompt.Height = 160;
prompt.Text = caption;
Label textLabel = new Label() { Left = 16, Top = 20, Width = 240, Text = text };
TextBox textBox = new TextBox() { Left = 16, Top = 40, Width = 240, TabIndex = 0, TabStop = true };
Label selLabel = new Label() { Left = 16, Top = 66, Width = 88, Text = selStr };
ComboBox cmbx = new ComboBox() { Left = 112, Top = 64, Width = 144 };
cmbx.Items.Add("Dark Grey");
cmbx.Items.Add("Orange");
cmbx.Items.Add("None");
Button confirmation = new Button() { Text = "In Ordnung!", Left = 16, Width = 80, Top = 88, TabIndex = 1, TabStop = true };
confirmation.Click += (sender, e) => { prompt.Close(); };
prompt.Controls.Add(textLabel);
prompt.Controls.Add(textBox);
prompt.Controls.Add(selLabel);
prompt.Controls.Add(cmbx);
prompt.Controls.Add(confirmation);
prompt.AcceptButton = confirmation;
prompt.StartPosition = FormStartPosition.CenterScreen;
prompt.ShowDialog();
return string.Format("{0};{1}", textBox.Text, cmbx.SelectedItem.ToString());
}
}
Both require the same usings:
using System;
using System.Windows.Forms;
Call them like so:
Call them like so:
PromptForTextAndBoolean.ShowDialog("Jazz", "What text should accompany the checkbox?", "Allow Scat Singing");
PromptForTextAndSelection.ShowDialog("Rock", "What should the name of the band be?", "Beret color to wear");
This is very simple and easily manage.

Curly braces are always needed for accessing array elements and carrying out brace expansion.
It's good to be not over-cautious and use {}
for shell variable expansion even when there is no scope for ambiguity.
For example:
dir=log
prog=foo
path=/var/${dir}/${prog} # excessive use of {}, not needed since / can't be a part of a shell variable name
logfile=${path}/${prog}.log # same as above, . can't be a part of a shell variable name
path_copy=${path} # {} is totally unnecessary
archive=${logfile}_arch # {} is needed since _ can be a part of shell variable name
So, it is better to write the three lines as:
path=/var/$dir/$prog
logfile=$path/$prog.log
path_copy=$path
which is definitely more readable.
Since a variable name can't start with a digit, shell doesn't need {}
around numbered variables (like $1
, $2
etc.) unless such expansion is followed by a digit. That's too subtle and it does make to explicitly use {}
in such contexts:
set app # set $1 to app
fruit=$1le # sets fruit to apple, but confusing
fruit=${1}le # sets fruit to apple, makes the intention clear
See:
I find it easier to remember to just read it and then write it.
For example:
with open('file') as f:
data = f.read()
with open('file', 'w') as f:
f.write('hello')
For those people with (cannot connect to localhost:5555: No connection could be made because the target machine actively refused it. (10061)
:
Blustacks is listening at IPv4-Localhost-TCP-5555
(not IPv6). Most of the time Windows has IPv6 enabled by default and Localhost is solving ::1:
If the client (ADB) tries to connect a server using localhost and IPv6 is enabled on the main network adapter, ADB will not connect to the server.
So, you have two options :
1- Change your ADB client TCP connection string to localhost IPV4 : adb connect 127.0.0.1
OR :
2-Disable IPV6 protocol from the main network adapter.
You need to that in two steps, at least.
First, click on the ¶ symbol in the toolbar: you can see if you have CRLF
line endings or just LF
.
Click on the Replace button, and put \r\n
or \n
, depending on the kind of line ending. In the Search Mode section of the dialog, check Extended radio button (interpret \n
and such).
Then replace all occurrences with nothing (empty string).
You end with a big line...
Next, in the same Replace dialog, put your delimiter (</Row>
) for example and in the Replace With field, put the same with a line ending (</Row>\r\n
). Replace All, and you are done.
Judging from my own experience, asmcrypto.js provides the fastest AES implementation in JavaScript (especially in Firefox since it can fully leverage asm.js there).
From the readme:
Chrome/31.0 SHA256: 51 MiB/s (9 times faster than SJCL and CryptoJS) AES-CBC: 47 MiB/s (13 times faster than CryptoJS and 20 times faster than SJCL) Firefox/26.0 SHA256: 144 MiB/s (5 times faster than CryptoJS and 20 times faster than SJCL) AES-CBC: 81 MiB/s (3 times faster than CryptoJS and 8 times faster than SJCL)
Edit: The Web Cryptography API is now implemented in most browsers and should be used as the primary solution if you care about performance. Be aware that IE11 implemented an earlier draft version of the standard which did not use promises.

Think this is, what you are searching for: Allow access to specific projects for Users
Short description without screenshots:
Use Jenkins "Project-based Matrix Authorization Strategy" under "Manage Jenkins" => "Configure System". On the configuration page of each project, you now have "Enable project-based security". Now add each user you want to authorize.
It is standard matplotlib.pyplot:
...
import matplotlib.pyplot as plt
plt.ylim(10, 40)
Or simpler, as mwaskom comments below:

Just to add to Ned's answer above: you can use this to redirect output to any object that implements a write(str) method.
This can be used to good effect to "catch" stdout output in a GUI application.
Here's a silly example in PyQt:
import sys
from PyQt4 import QtGui
class OutputWindow(QtGui.QPlainTextEdit):
def write(self, txt):
self.appendPlainText(str(txt))
app = QtGui.QApplication(sys.argv)
out = OutputWindow()
sys.stdout=out
out.show()
print "hello world !"
To use the least amount of space you should use a CHAR field constrained to 'Y' or 'N'. Oracle doesn't support BOOLEAN, BIT, or TINYINT data types, so CHAR's one byte is as small as you can get.
For more modularity and in case you have many background images that you want to incorporate wherever you want you can for each image create a class :
.background-image1
{
background: url(image1.jpg);
}
.background-image2
{
background: url(image2.jpg);
}
and then insert the image wherever you want by adding a div
<div class='background-image1'>
<div class="page-header text-center", style='margin: 20px 0 0px;'>
<h1>blabaaboabaon</h1>
</div>
</div>
This is a follow up to my previous answer and contains C++11 related material..
Pre-requisites : An elementary knowledge of Relations (Mathematics).
Yes! This is very true.
Sequence Points have been replaced by Sequenced Before and Sequenced After (and Unsequenced and Indeterminately Sequenced) relations in C++11.
Sequenced Before(§1.9/13) is a relation which is:
between evaluations executed by a single thread and induces a strict partial order1
Formally it means given any two evaluations(See below) A
and B
, if A
is sequenced before B
, then the execution of A
shall precede the execution of B
. If A
is not sequenced before B
and B
is not sequenced before A
, then A
and B
are unsequenced 2.
Evaluations A
and B
are indeterminately sequenced when either A
is sequenced before B
or B
is sequenced before A
, but it is unspecified which3.
[NOTES]
1 : A strict partial order is a binary relation "<"
over a set P
which is asymmetric
, and transitive
, i.e., for all a
, b
, and c
in P
, we have that:
........(i). if a < b then ¬ (b < a) (asymmetry
);
........(ii). if a < b and b < c then a < c (transitivity
).
2 : The execution of unsequenced evaluations can overlap.
3 : Indeterminately sequenced evaluations cannot overlap, but either could be executed first.
In C++11, evaluation of an expression (or a sub-expression) in general includes:
value computations (including determining the identity of an object for glvalue evaluation and fetching a value previously assigned to an object for prvalue evaluation) and
initiation of side effects.
Now (§1.9/14) says:
Every value computation and side effect associated with a full-expression is sequenced before every value computation and side effect associated with the next full-expression to be evaluated.
Trivial example:
int x;
x = 10;
++x;
Value computation and side effect associated with ++x
is sequenced after the value computation and side effect of x = 10;
Yes! Right.
In (§1.9/15) it has been mentioned that
Except where noted, evaluations of operands of individual operators and of subexpressions of individual expressions are unsequenced4.
For example :
int main()
{
int num = 19 ;
num = (num << 3) + (num >> 3);
}
+
operator are unsequenced relative to each other.<<
and >>
operators are unsequenced relative to each other.4: In an expression that is evaluated more than once during the execution of a program, unsequenced and indeterminately sequenced evaluations of its subexpressions need not be performed consistently in different evaluations.
(§1.9/15) The value computations of the operands of an operator are sequenced before the value computation of the result of the operator.
That means in x + y
the value computation of x
and y
are sequenced before the value computation of (x + y)
.
More importantly
(§1.9/15) If a side effect on a scalar object is unsequenced relative to either
(a) another side effect on the same scalar object
or
(b) a value computation using the value of the same scalar object.
the behaviour is undefined.
Examples:
int i = 5, v[10] = { };
void f(int, int);
i = i++ * ++i; // Undefined Behaviour
i = ++i + i++; // Undefined Behaviour
i = ++i + ++i; // Undefined Behaviour
i = v[i++]; // Undefined Behaviour
i = v[++i]: // Well-defined Behavior
i = i++ + 1; // Undefined Behaviour
i = ++i + 1; // Well-defined Behaviour
++++i; // Well-defined Behaviour
f(i = -1, i = -1); // Undefined Behaviour (see below)
When calling a function (whether or not the function is inline), every value computation and side effect associated with any argument expression, or with the postfix expression designating the called function, is sequenced before execution of every expression or statement in the body of the called function. [Note: Value computations and side effects associated with different argument expressions are unsequenced. — end note]
Expressions (5)
, (7)
and (8)
do not invoke undefined behaviour. Check out the following answers for a more detailed explanation.

Seems like the order of the linking flags was not an issue in older versions of gcc. Eg gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-16)
comes with Centos-6.7 happy with linker option before inputfile; but gcc with ubuntu 16.04 gcc (Ubuntu 5.3.1-14ubuntu2.1) 5.3.1 20160413
does not allow.
Its not the gcc version alone, I has got something to with the distros
I had the same issue as OP (I think!), but I couldn't get it to work in the way that Lastalda specified. I don't know if I have interpreted the question properly, but I have found another solution (it probably is a really bad way of doing it though).
This was the way that I did it:
plt.hist([1,11,21,31,41], bins=[0,10,20,30,40,50], weights=[10,1,40,33,6]);
Which creates this:
So the first parameter basically 'initialises' the bin - I'm specifically creating a number that is in between the range I set in the bins parameter.
To demonstrate this, look at the array in the first parameter ([1,11,21,31,41]) and the 'bins' array in the second parameter ([0,10,20,30,40,50]):
Then I'm using the 'weights' parameter to define the size of each bin. This is the array used for the weights parameter: [10,1,40,33,6].
So the 0 to 10 bin is given the value 10, the 11 to 20 bin is given the value of 1, the 21 to 30 bin is given the value of 40, etc.
Add:
DELIMITER
at the beginning and end of the SP.validar_egreso
; at the beginning@variableName
.This works for me. (I modified some part of your script so ANYONE can run it with out having your tables).
DROP PROCEDURE IF EXISTS `validar_egreso`;
DELIMITER $$
CREATE DEFINER='root'@'localhost' PROCEDURE `validar_egreso` (
IN codigo_producto VARCHAR(100),
IN cantidad INT,
OUT valido INT(11)
)
BEGIN
DECLARE resta INT;
SET resta = 0;
SELECT (codigo_producto - cantidad) INTO resta;
IF(resta > 1) THEN
SET valido = 1;
ELSE
SET valido = -1;
END IF;
SELECT valido;
END $$
DELIMITER ;
-- execute the stored procedure
CALL validar_egreso(4, 1, @val);
-- display the result
select @val;
Because git has the cool ability to push/pull different branches to different "upstream" repositories. You could even use separate repositories for pushing and pulling - on the same branch. This can create a distributed, multi-level flow, I can see this being useful on project such as the Linux kernel. Git was originally built to be used on that project.
As a consequence, it does not make assumption about which repo your branch should be tracking.
On the other hand, most people do not use git in this way, so it might make a good case for a default option.
Git is generally pretty low-level and it can be frustrating. Yet there are GUIs and it should be easy to write helper scripts if you still want to use it from the shell.
They are equivalent, from the standard (emphasis mine) (7.1.3.2):
A typedef-name can also be introduced by an alias-declaration. The identifier following the using keyword becomes a typedef-name and the optional attribute-specifier-seq following the identifier appertains to that typedef-name. It has the same semantics as if it were introduced by the typedef specifier. In particular, it does not define a new type and it shall not appear in the type-id.
The beauty of *nix tools is you can combine them:
ls -l | sort -k9,9
The output of ls -l
will look like this
-rw-rw-r-- 1 luckydonald luckydonald 532 Feb 21 2017 Makefile
-rwxrwxrwx 1 luckydonald luckydonald 4096 Nov 17 23:47 file.txt
So with 9,9
you sort column 9
up to the column 9
, being the file names. You have to provide where to stop, which is the same column in this case. The columns start with 1
.
Also, if you want to ignore upper/lower case, add --ignore-case
to the sort command.
An array in PHP is a map of keys to values:
$array = array();
$array["yellow"] = 3;
$array["green"] = 4;
If you want to do something with each key-value-pair in your array, you can use the foreach
control structure:
foreach ($array as $key => $value)
The $array variable is the array you will be using. The $key and $value variables will contain a key-value-pair in every iteration of the foreach
loop. In this example, they will first contain "yellow" and 3, then "green" and 4.
You can use an alternative notation if you don't care about the keys:
foreach ($array as $value)
Amazon EC2 instances are just virtual machines so you would setup SSL the same way you would set it up on any server.
You don't mention what platform you are on, so it difficult to give any more information.
To add to svick's answer, the -m
option simply adds a message to your stash, and is entirely optional. Thus, the command
git stash push [paths you wish to stash]
is perfectly valid. So for instance, if I want to only stash changes in the src/
directory, I can just run
git stash push src/
I agree with chrylis: you believe you changed your project's compliance settings but probably you didnt.
Right click on your project and:
By the way you can "tell" eclipse that jre8 is 1.6 compliance clicking on Window/Preferences/Java/Installed JREs/Execution Environment and selecting in the left panel, Execution Environments, JavaSE-1.6 and in the Compatible JRE's panel, jre8

Basically $(this).fadeOut().next().fadeIn();
is what you require
You can also cheat in some way by hidding a submit button on your form and triggering it when you click on your modal button.
Try the following:
var filteredFileSet = fileList.Where(item => filterList.Contains(item));
When you iterate over filteredFileSet (See LINQ Execution) it will consist of a set of IEnumberable values. This is based on the Where Operator checking to ensure that items within the fileList data set are contained within the filterList set.
As fileList is an IEnumerable set of string values, you can pass the 'item' value directly into the Contains method.
To get the absolute position of an UI element within the window you can use:
Point position = desiredElement.PointToScreen(new Point(0d, 0d));
If you are within an User Control, and simply want relative position of the UI element within that control, simply use:
Point position = desiredElement.PointToScreen(new Point(0d, 0d)),
controlPosition = this.PointToScreen(new Point(0d, 0d));
position.X -= controlPosition.X;
position.Y -= controlPosition.Y;

In a query you can just do something like:
SELECT ColumnA * ColumnB FROM table
or
SELECT ColumnA - ColumnB FROM table
You can also create computed columns in your table where you can permanently use your formula.
Just add this and all works well:
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0">
Just with bash:
convert_date () {
local months=( JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC )
local i
for (( i=0; i<11; i++ )); do
[[ $2 = ${months[$i]} ]] && break
done
printf "%4d%02d%02d\n" $3 $(( i+1 )) $1
}
And invoke it like this
d=$( convert_date 27 JUN 2011 )
Or if the "old" date string is stored in a variable
d_old="27 JUN 2011"
d=$( convert_date $d_old ) # not quoted
You can use Chr(13). Then just wrap the whole thing in Chr(34). Chr(34) is double quotes.

In the endpoint tag you need to include the property address=""
<endpoint address="" binding="webHttpBinding" bindingConfiguration="SecureBasicRest" behaviorConfiguration="svcEndpoint" name="webHttp" contract="SvcContract.Authenticate" />
I guess you want to do this in i line. It is possible (a bit of juggling though =^)
new StringBuilder(new StringBuilder("Düsseldorf - Zentrum - Günnewig Uebachs").reverse().toString().split(" - ")[0]).reverse()
tadaa, one line -> the result you want (if you split on " - " (space minus space) instead of only "-" (minus) you will loose the annoying space before the partition too =^) so "Günnewig Uebachs" instead of " Günnewig Uebachs" (with a space as first character)
Nice extra -> no need for extra JAR files in the lib folder so you can keep your application light weight.
Even in base Python you can do the computation in generic form
result = sum(x**2 for x in some_vector) ** 0.5
x ** 2
is surely not an hack and the computation performed is the same (I checked with cpython source code). I actually find it more readable (and readability counts).
Using instead x ** 0.5
to take the square root doesn't do the exact same computations as math.sqrt
as the former (probably) is computed using logarithms and the latter (probably) using the specific numeric instruction of the math processor.
I often use x ** 0.5
simply because I don't want to add math
just for that. I'd expect however a specific instruction for the square root to work better (more accurately) than a multi-step operation with logarithms.
I disagree with the recommendation to create separate CSS files for non-editorial images.
Assuming the images are for UI purposes, it's presentation layer styling, and as mentioned above, if you're doing mobile UI's its definitely a good idea to keep all styling in a single file so it can be cached once.
The "||" or the "??" comes in handy here
Best choice and IE compatible is the ||
for (Object object : someList || []) {
// undefined and null gets defaulted to an empty array []
}
Nullish coalescing operator: Not IE compatible
for (Object object : someList ?? []) {
// undefined and null gets defaulted to an empty array []
}
If it still actual for someone, my solution was as follows:
.container{
overflow: hidden;
overflow-y: auto;
}
If you don't know how many columns you are going to have, the declaration
table-layout: fixed
along with not setting any column widths, would imply that browsers divide the total width evenly - no matter what.
That can also be the problem with this approach, if you use this, you should also consider how overflow is to be handled.
Changing the web.config generally causes an application restart.
If you really need your application to edit its own settings, then you should consider a different approach such as databasing the settings or creating an xml file with the editable settings.
I still remember the first weeks of my programming courses and I totally understand how you feel. Here is the code that solves your problem. In order to learn from this answer, try to run it adding several 'print' in the loop, so you can see the progress of the variables.
import java.util.*;
import java.lang.*;
public class foo
{
public static void main(String[] args)
{
double[] alpha = new double[50];
int count = 0;
for (int i=0; i<50; i++)
{
// System.out.print("variable i = " + i + "\n");
if (i < 25)
{
alpha[i] = i*i;
}
else {
alpha[i] = 3*i;
}
if (count < 10)
{
System.out.print(alpha[i]+ " ");
}
else {
System.out.print("\n");
System.out.print(alpha[i]+ " ");
count = 0;
}
count++;
}
System.out.print("\n");
}
}
Have you considered simply using System.Drawing namespace? For example:
System.Drawing.Color color = System.Drawing.Color.FromArgb(red, green, blue);
float hue = color.GetHue();
float saturation = color.GetSaturation();
float lightness = color.GetBrightness();
Note that it's not exactly what you've asked for (see differences between HSL and HSV and the Color class does not have a conversion back from HSL/HSV but the latter is reasonably easy to add.
document.getElementById("fname").style.borderTopColor = 'red';
document.getElementById("fname").style.borderBottomColor = 'red';
I had the same problem, so I wrote a Ruby gem called Twig. It lists branches in chronological order (newest first), and can also let you set a max age so that you don't list all branches (if you have a lot of them). For example:
$ twig
issue status todo branch
----- ------ ---- ------
2013-01-26 18:00:21 (7m ago) 486 In progress Rebase optimize-all-the-things
2013-01-26 16:49:21 (2h ago) 268 In progress - whitespace-all-the-things

2013-01-20 19:45:42 (6d ago) - - - master
It also lets you store custom properties for each branch, e.g., ticket id, status, todos, and filter the list of branches according to these properties. More info: http://rondevera.github.io/twig/
Two ways
window.frames['myIFrame'].contentDocument.getElementById('myIFrameElemId')
OR
window.frames['myIFrame'].contentWindow.document.getElementById('myIFrameElemId')
The accepted answer by Aristotle will show all reachable commits, including non-stash-like commits. To filter out the noise:
git fsck --no-reflog | \
awk '/dangling commit/ {print $3}' | \
xargs git log --no-walk --format="%H" \
--grep="WIP on" --min-parents=3 --max-parents=3
This will only include commits which have exactly 3 parent commits (which a stash will have), and whose message includes "WIP on".
Keep in mind, that if you saved your stash with a message (e.g. git stash save "My newly created stash"
), this will override the default "WIP on..." message.
You can display more information about each commit, e.g. display the commit message, or pass it to git stash show
:
git fsck --no-reflog | \
awk '/dangling commit/ {print $3}' | \
xargs git log --no-walk --format="%H" \
--grep="WIP on" --min-parents=3 --max-parents=3 | \
xargs -n1 -I '{}' bash -c "\
git log -1 --format=medium --color=always '{}'; echo; \
git stash show --color=always '{}'; echo; echo" | \
less -R
To directly answer your question, yes, you can mock some methods without mocking others. This is called a partial mock. See the Mockito documentation on partial mocks for more information.
For your example, you can do something like the following, in your test:
Stock stock = mock(Stock.class);
when(stock.getPrice()).thenReturn(100.00); // Mock implementation
when(stock.getQuantity()).thenReturn(200); // Mock implementation
when(stock.getValue()).thenCallRealMethod(); // Real implementation
In that case, each method implementation is mocked, unless specify thenCallRealMethod()
in the when(..)
clause.
There is also a possibility the other way around with spy instead of mock:
Stock stock = spy(Stock.class);
when(stock.getPrice()).thenReturn(100.00); // Mock implementation
when(stock.getQuantity()).thenReturn(200); // Mock implementation
// All other method call will use the real implementations
In that case, all method implementation are the real one, except if you have defined a mocked behaviour with when(..)
.
There is one important pitfall when you use when(Object)
with spy like in the previous example. The real method will be called (because stock.getPrice()
is evaluated before when(..)
at runtime). This can be a problem if your method contains logic that should not be called. You can write the previous example like this:
Stock stock = spy(Stock.class);
doReturn(100.00).when(stock).getPrice(); // Mock implementation
doReturn(200).when(stock).getQuantity(); // Mock implementation
// All other method call will use the real implementations
Another possibility may be to use org.mockito.Mockito.CALLS_REAL_METHODS
, such as:
Stock MOCK_STOCK = Mockito.mock( Stock.class, CALLS_REAL_METHODS );
This delegates unstubbed calls to real implementations.
However, with your example, I believe it will still fail, since the implementation of getValue()
relies on quantity
and price
, rather than getQuantity()
and getPrice()
, which is what you've mocked.
Another possibility is to avoid mocks altogether:
@Test
public void getValueTest() {
Stock stock = new Stock(100.00, 200);
double value = stock.getValue();
assertEquals("Stock value not correct", 100.00*200, value, .00001);
}
How about:
echo "hello" >> <filename>
Using the >>
operator will append data at the end of the file, while using the >
will overwrite the contents of the file if already existing.
You could also use printf
in the same way:
printf "hello" >> <filename>
Note that it can be dangerous to use the above. For instance if you already have a file and you need to append data to the end of the file and you forget to add the last >
all data in the file will be destroyed. You can change this behavior by setting the noclobber
variable in your .bashrc
:
set -o noclobber
Now when you try to do echo "hello" > file.txt
you will get a warning saying cannot overwrite existing file
.
To force writing to the file you must now use the special syntax:
echo "hello" >| <filename>
You should also know that by default echo
adds a trailing new-line character which can be suppressed by using the -n
flag:
echo -n "hello" >> <filename>

To clarify, a database created under SQL Server 2008 R2 was being opened in an instance of SQL Server 2008 (the version prior to R2). The solution for me was to simply perform an upgrade installation of SQL Server 2008 R2. I can only speak for the Express edition, but it worked.
Oddly, though, the Web Platform Installer indicated that I had Express R2 installed. The better way to tell is to ask the database server itself:
SELECT @@VERSION
Like this:
>>>mystr = "abcdefghijkl"
>>>mystr[-4:]
'ijkl'
This slices the string's last 4 characters. The -4 starts the range from the string's end. A modified expression with [:-4]
removes the same 4 characters from the end of the string:
>>>mystr[:-4]
'abcdefgh'
For more information on slicing see this Stack Overflow answer.
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.
It sounds less like a Java synchronization issue and more like a database locking problem.
I don't know if adding a version to all your persistent classes will sort it out, but that's one way that Hibernate can provide exclusive access to rows in a table.
Could be that isolation level needs to be higher. If you allow "dirty reads", maybe you need to bump up to serializable.
It happens because you call it before DOM has loaded. Firstly, create the element and add atrributes to it, then after DOM has loaded call it. In your case it should look like that:
var canvas = document.createElement('canvas');
canvas.id = "CursorLayer";
canvas.width = 1224;
canvas.height = 768;
canvas.style.zIndex = 8;
canvas.style.position = "absolute";
canvas.style.border = "1px solid";
window.onload = function() {
document.getElementById("CursorLayer");
}
I would use math
package for getting the maximal value and minimal value :
func printMinMaxValue() {
// integer max
fmt.Printf("max int64 = %+v\n", math.MaxInt64)
fmt.Printf("max int32 = %+v\n", math.MaxInt32)
fmt.Printf("max int16 = %+v\n", math.MaxInt16)
// integer min
fmt.Printf("min int64 = %+v\n", math.MinInt64)
fmt.Printf("min int32 = %+v\n", math.MinInt32)
fmt.Printf("max flloat64= %+v\n", math.MaxFloat64)
fmt.Printf("max float32= %+v\n", math.MaxFloat32)
// etc you can see more int the `math`package
}
Ouput :
max int64 = 9223372036854775807
max int32 = 2147483647
max int16 = 32767
min int64 = -9223372036854775808
min int32 = -2147483648
max flloat64= 1.7976931348623157e+308
max float32= 3.4028234663852886e+38
The final outcome of the conversion is that the number of elements in the final array is same as that of the initial array or data frame.
-1 corresponds to the unknown count of the row or column.
We can think of it as x
(unknown). x
is obtained by dividing the number of elements in the original array by the other value of the ordered pair with -1.
Examples:
12 elements with reshape(-1,1)
corresponds to an array with x
=12/1=12 rows and 1 column.
12 elements with reshape(1,-1)
corresponds to an array with 1 row and x
=12/1=12 columns.

You're declaring everything in the parent page. So the references to window
and document
are to the parent page's. If you want to do stuff to the iframe
's, use iframe || iframe.contentWindow
to access its window
, and iframe.contentDocument || iframe.contentWindow.document
to access its document
.
There's a word for what's happening, possibly "lexical scope": What is lexical scope?
The only context of a scope is this. And in your example, the owner of the method is doc
, which is the iframe
's document
. Other than that, anything that's accessed in this function that uses known objects are the parent's (if not declared in the function). It would be a different story if the function were declared in a different place, but it's declared in the parent page.
This is how I would write it:
(function () {
var dom, win, doc, where, iframe;
iframe = document.createElement('iframe');
iframe.src = "javascript:false";
where = document.getElementsByTagName('script')[0];
where.parentNode.insertBefore(iframe, where);
win = iframe.contentWindow || iframe;
doc = iframe.contentDocument || iframe.contentWindow.document;
doc.open();
doc._l = (function (w, d) {
return function () {
w.vanishing_global = new Date().getTime();
var js = d.createElement("script");
js.src = 'test-vanishing-global.js?' + w.vanishing_global;
w.name = "foobar";
d.foobar = "foobar:" + Math.random();
d.foobar = "barfoo:" + Math.random();
d.body.appendChild(js);
};
})(win, doc);
doc.write('<body onload="document._l();"></body>');
doc.close();
})();
The aliasing of win
and doc
as w
and d
aren't necessary, it just might make it less confusing because of the misunderstanding of scopes. This way, they are parameters and you have to reference them to access the iframe
's stuff. If you want to access the parent's, you still use window
and document
.
I'm not sure what the implications are of adding methods to a document
(doc
in this case), but it might make more sense to set the _l
method on win
. That way, things can be run without a prefix...such as <body onload="_l();"></body>
This is more robust:
mi = location.href.split(/(\d+)/);
no = mi.length - 2;
os = mi[no];
mi[no]++;
if ((mi[no] + '').length < os.length) mi[no] = os.match(/0+/) + mi[no];
location.href = mi.join('');
When the URL has multiple numbers, it will change the last one:
http://mywebsite.com/8815/1.html
It supports numbers with leading zeros:
http://mywebsite.com/0001.html

You want to use single quotes:
if(c=='\0')
Double quotes (") are for strings, which are sequences of characters. Single quotes (') are for individual characters.
However, the end-of-line is represented by the newline character, which is '\n'.
Note that in both cases, the backslash is not part of the character, but just a way you represent special characters. Using backslashes you can represent various unprintable characters and also characters which would otherwise confuse the compiler.
Also, in your html, remember to delete all blanks / line feeds / tabs between the closing tag and the opening tag.
<img src='a.png' /> <img src='b.png' />
will always display a space between the images even if the border attribute is set to 0, whereas <img src='a.png' /><img src='b.png' />
will not.
I recently encountered this problem while working on a contract project(deemed classified). The system in which I had to run the code did not have internet access, for security purposes of course, and so installing dependencies, using composer and npm, was becoming huge pain.
After much deliberation with my colleague, we decided to just wing it and copy paste our dependencies rather than doing composer install or npm install.
This led us to NOT add vendors and npm_modules in gitignore. This is when I encountered this problem.
Changed but not updated:
modified: vendor/plugins/open_flash_chart_2 (modified content, untracked content)
I googled this a bit and found this helpful thread on SO. Not being too much of a pro in Git, and being a little intoxicated while working on it, I just searched for all the submodules in the vendors folder
find . -name ".git"
This gave me some 4-5 dependencies that had git on them. I removed all these .git folders and voila, it worked. I knows it's hack, and not a very geeky one anyways. O Gods of SO, please forgive me! Next time I promise to read up on gitlinks and obey O mighty Linus Tovalds.
The answer is in here :
To declare a bounded type parameter, list the type parameter's name, followed by the
extends
keyword, followed by its upper bound […]. Note that, in this context, extends is used in a general sense to mean eitherextends
(as in classes) orimplements
(as in interfaces).
So there you have it, it's a bit confusing, and Oracle knows it.
As the error message states, jQuery does not include a :unchecked
selector.
Instead, you need to invert the :checked
selector:
$("input:checkbox:not(:checked)")
You can find the headers option in the Network tab in Developer's console in Chrome:
Also, in my version of Chrome (50.0.2661.102), it gives an extension named LIVE HTTP Headers which gives information about the request headers for all the HTTP requests.
update: added image
We also had this problem. My colleague found a solution. It turned up to be a redefinition of "main" in a third party library header:
#define main SDL_main
So the solution was to add:
#undef main
before our main function.
This is clearly a stupidity!
SQLDataReaders are forward-only. You're essentially doing this:
count++; // initially 1
.DataBind(); //consuming all the records
//next iteration on
.Read()
//we've now come to end of resultset, thanks to the DataBind()
//count is still 1
You could do this instead:
if (reader.HasRows)
{
rep.DataSource = reader;
rep.DataBind();
}
int count = rep.Items.Count; //somehow count the num rows/items `rep` has.

You don't need to write js to do that, simply use:
<a href="path_to/image.jpg" alt="something">Download image</a>
And the browser itself will automatically download the image.
If for some reason it doesn't work add the download attribute. With this attribute you can set a name for the downloadable file:
<a href="path_to/image.jpg" download="myImage">Download image</a>
To support delta
const range = (start, end, delta) => {
return Array.from(
{length: (end - start) / delta}, (v, k) => (k * delta) + start
)
};
This is what may be happening, if the value of item.photo
is undefined then item.photo != ''
will always show as true. And if you think logically it actually makes sense, item.photo
is not an empty string (so this condition comes true) since it is undefined
.
Now for people who are trying to check if the value of input is empty or not in Angular 6, can go by this approach.
Lets say this is the input field -
<input type="number" id="myTextBox" name="myTextBox"_x000D_
[(ngModel)]="response.myTextBox"_x000D_
#myTextBox="ngModel">
_x000D_
To check if the field is empty or not this should be the script.
<div *ngIf="!myTextBox.value" style="color:red;">_x000D_
Your field is empty_x000D_
</div>
_x000D_
Do note the subtle difference between the above answer and this answer. I have added an additional attribute .value
after my input name myTextBox
.
I don't know if the above answer worked for above version of Angular, but for Angular 6 this is how it should be done.

It says that it should be a 64-bit JDK. I have a feeling that you installed (at a previous time) a 32-bit version of Java. The path for all 32-bit applications in Windows 7 and Vista is:
C:\Program Files (x86)\
You were setting the JAVA_HOME
variable to the 32-bit version of Java. Set your JAVA_HOME
variable to the following:
C:\Program Files\Java\jdk1.7.0_45
If that does not work, check that the JDK version is 1.7.0_45. If not, change the JAVA_HOME
variable to (with JAVAVERSION
as the Java version number:
C:\Program Files\Java\jdkJAVAVERSION

This answer is for anyone encountering pdfs with images and needing to use OCR. I could not find a workable off-the-shelf solution; nothing that gave me the accuracy I needed.
Here are the steps I found to work.
Use pdfimages
from https://poppler.freedesktop.org/ to turn the pages of the pdf into images.
Use Tesseract to detect rotation and ImageMagick mogrify
to fix it.
Use OpenCV to find and extract tables.
Use OpenCV to find and extract each cell from the table.
Use OpenCV to crop and clean up each cell so that there is no noise that will confuse OCR software.
Use Tesseract to OCR each cell.
Combine the extracted text of each cell into the format you need.
I wrote a python package with modules that can help with those steps.
Repo: https://github.com/eihli/image-table-ocr
Docs & Source: https://eihli.github.io/image-table-ocr/pdf_table_extraction_and_ocr.html
Some of the steps don't require code, they take advantage of external tools like pdfimages
and tesseract
. I'll provide some brief examples for a couple of the steps that do require code.

# Leaving that step as a future TODO if it is ever necessary.
images = [image[y:y+h, x:x+w] for x, y, w, h in bounding_rects]
return images
This is very similar to 2, so I won't include all the code. The part I will reference will be in sorting the cells.
We want to identify the cells from left-to-right, top-to-bottom.
We’ll find the rectangle with the most top-left corner. Then we’ll find all of the rectangles that have a center that is within the top-y and bottom-y values of that top-left rectangle. Then we’ll sort those rectangles by the x value of their center. We’ll remove those rectangles from the list and repeat.
def cell_in_same_row(c1, c2):
c1_center = c1[1] + c1[3] - c1[3] / 2
c2_bottom = c2[1] + c2[3]
c2_top = c2[1]
return c2_top < c1_center < c2_bottom
orig_cells = [c for c in cells]
rows = []
while cells:
first = cells[0]
rest = cells[1:]
cells_in_same_row = sorted(
[
c for c in rest
if cell_in_same_row(c, first)
],
key=lambda c: c[0]
)
row_cells = sorted([first] + cells_in_same_row, key=lambda c: c[0])
rows.append(row_cells)
cells = [
c for c in rest
if not cell_in_same_row(c, first)
]
# Sort rows by average height of their center.
def avg_height_of_center(row):
centers = [y + h - h / 2 for x, y, w, h in row]
return sum(centers) / len(centers)
rows.sort(key=avg_height_of_center)
There's interesting stuff on the performance aspects in this question
However I personally would still recommend string.Format
unless performance is critical for readability reasons.
string.Format("{0}: {1}", key, value);
Is more readable than
key + ": " + value
For instance. Also provides a nice separation of concerns. Means you can have
string.Format(GetConfigValue("KeyValueFormat"), key, value);
And then changing your key value format from "{0}: {1}"
to "{0} - {1}"
becomes a config change rather than a code change.
string.Format
also has a bunch of format provision built into it, integers, date formatting, etc.
$cookie_name = "my cookie";
$cookie_value = "my value";
$cookie_new_value = "my new value";
// Create a cookie,
setcookie($cookie_name, $cookie_value , time() + (86400 * 30), "/"); //86400 = 24 hours in seconds
// Get value in a cookie,
$cookie_value = $_COOKIE[$cookie_name];
// Update a cookie,
setcookie($cookie_name, $cookie_new_value , time() + (86400 * 30), "/");
// Delete a cookie,
setcookie($cookie_name, '' , time() - 3600, "/"); // time() - 3600 means, set the cookie expiration date to the past hour.
The Access denied is because Windows doesn't give the default write and modify permission to the files in its install drive viz. c: To resolve this issue I usually use a separate drive or in your case, you need to set the access rights to the specific folder in the options right click -> options > security -> edit
I had the same problem, ruby-1.8.7-p357, and tried loads of things in vain...
I finally realised that it happens only on multiple calls using the same XMLRPC::Client instance!
So now I'm re-instantiating my client at each call and it just works:|
You could have is_hammer
in terms of row["Open"]
etc. as follows
def is_hammer(rOpen,rLow,rClose,rHigh):
return lower_wick_at_least_twice_real_body(rOpen,rLow,rClose) \
and closed_in_top_half_of_range(rHigh,rLow,rClose)
Then you can use map:
df["isHammer"] = map(is_hammer, df["Open"], df["Low"], df["Close"], df["High"])
DocumentFilter ? It gives you the ability to manipulate.

Older versions of JSP did not support the second syntax.
Tried following code
$db = new PDO("mysql:host={$dbhost};dbname={$dbname};charset=utf8", $dbuser, $dbpass, array(PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION));
Then
try {
$db->query('SET NAMES gbk');
$stmt = $db->prepare('SELECT * FROM 2_1_paidused WHERE NumberRenamed = ? LIMIT 1');
$stmt->execute(array("\xbf\x27 OR 1=1 /*"));
}
catch (PDOException $e){
echo "DataBase Errorz: " .$e->getMessage() .'<br>';
}
catch (Exception $e) {
echo "General Errorz: ".$e->getMessage() .'<br>';
}
And got
DataBase Errorz: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '/*' LIMIT 1' at line 1
If added $db->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
after $db = ...
Then got blank page
If instead SELECT
tried DELETE
, then in both cases got error like
DataBase Errorz: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '* FROM 2_1_paidused WHERE NumberRenamed = '¿\' OR 1=1 /*' LIMIT 1' at line 1
So my conclusion that no injection possible...
With newer versions of excel come new functions and thus new methods. Though it's replicable in older versions (yet I have not seen it before), when one has Excel O365 one can use:
=MATCH(2,1/(MID(A1,SEQUENCE(LEN(A1)),1)="Y"))
This can also be used to retrieve the last position of (overlapping) substrings:
=MATCH(2,1/(MID(A1,SEQUENCE(LEN(A1)),2)="YY"))
| Value | Pattern | Formula | Position |
|--------|---------|------------------------------------------------|----------|
| XYYZ | Y | =MATCH(2,1/(MID(A2,SEQUENCE(LEN(A2)),1)="Y")) | 3 |
| XYYYZ | YY | =MATCH(2,1/(MID(A3,SEQUENCE(LEN(A3)),2)="YY")) | 3 |
| XYYYYZ | YY | =MATCH(2,1/(MID(A4,SEQUENCE(LEN(A4)),2)="YY")) | 4 |
Whilst this both allows us to no longer use an arbitrary replacement character and it allows overlapping patterns, the "downside" is the useage of an array.
Note: You can force the same behaviour in older Excel versions through either
=MATCH(2,1/(MID(A2,ROW(A1:INDEX(A:A,LEN(A2))),1)="Y"))
Entered through CtrlShiftEnter, or using an inline INDEX
to get rid of implicit intersection:
=MATCH(2,INDEX(1/(MID(A2,ROW(A1:INDEX(A:A,LEN(A2))),1)="Y"),))
I think Sanjay's answer was almost there but i used it this way
NSArray *myArray = [[NSArray alloc] initWithObjects:@"Hello",@"World", nil];
NSString *greeting = [myArray componentsJoinedByString:@" "];
NSLog(@"%@",greeting);
Output :
2015-01-25 08:47:14.830 StringTest[11639:394302] Hello World
As Sanjay had hinted - I used method componentsJoinedByString from NSArray that does joining and gives you back NSString
BTW NSString has reverse method componentsSeparatedByString that does the splitting and gives you NSArray back .
You can use:
public YourClass[] AllProducts()
{
try
{
using (UserDataDataContext db = new UserDataDataContext())
{
return db.mrobProducts.Where(x => x.Status == 1)
.OrderBy(x => x.ID)
.Select(x => new YourClass { ID = x.ID, Name = x.Name, Price = x.Price})
.ToArray();
}
}
catch
{
return null;
}
}
And here is YourClass
implementation:
public class YourClass
{
public string Name {get; set;}
public int ID {get; set;}
public int Price {get; set;}
}
And your AllProducts
method's return type must be YourClass[]
.
It appears statics are deprecated, and the other methods of exposing some functions with render
seem convoluted. Meanwhile, this Stack Overflow answer about debugging React, while seeming hack-y, did the job for me.
you can apply two commands
git diff --patch > mypatch.patch // to generate the patch
git apply mypatch.patch // to apply the patch
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')
.
$("#radio1").attr('checked', true).trigger('click');
This answer is similar to some answers above. However, I feel that it would be beneficial because, unlike other answers, this will remove any extra commas or whitespace and handles abbreviation.
/**

*/
public static String millisToString(long millis, boolean longFormat) {
if (millis < 1000) {
return String.format("0 %s", longFormat ? "seconds" : "secs");
}
String[] units = {
"day", "hour", longFormat ? "minute" : "min", longFormat ? "second" : "sec"
};
long[] times = new long[4];
times[0] = TimeUnit.DAYS.convert(millis, TimeUnit.MILLISECONDS);
millis -= TimeUnit.MILLISECONDS.convert(times[0], TimeUnit.DAYS);
times[1] = TimeUnit.HOURS.convert(millis, TimeUnit.MILLISECONDS);

StringBuilder s = new StringBuilder();
for (int i = 0; i < 4; i++) {
if (times[i] > 0) {
s.append(String.format("%d %s%s, ", times[i], units[i], times[i] == 1 ? "" : "s"));
}
}
return s.toString().substring(0, s.length() - 2);
}

public static String millisToString(long millis) {
return millisToString(millis, false);
}
You can also use eval()
to do the same thing.
//A function to call
function needToBeCalled(p1, p2)
{
alert(p1+"="+p2);
}
//A function where needToBeCalled passed as an argument with necessary params
//Here params is comma separated string
function callAnotherFunction(aFunction, params)
{
eval(aFunction + "("+params+")");
}
//A function Call
callAnotherFunction("needToBeCalled", "10,20");
That's it. I was also looking for this solution and tried solutions provided in other answers but finally got it work from above example.
In simplest words :P If it is safe to execute multiple threads on a block of code it is thread safe*
*conditions apply
Conditions are mentioned by other answeres like 1. The result should be same if you execute one thread or multiple threads over it etc.
#Forwarding Pattern => the best practice on JS overloading Forward to another function which name is built from the 3rd & 4th points :
- Using number of arguments
- Checking types of arguments
window['foo_'+arguments.length+'_'+Array.from(arguments).map((arg)=>typeof arg).join('_')](...arguments)
#Application on your case :
function foo(...args){
return window['foo_' + args.length+'_'+Array.from(args).map((arg)=>typeof arg).join('_')](...args);
}
//------Assuming that `x` , `y` and `z` are String when calling `foo` .

}
#Other Complex Sample :
function foo(...args){

OK, finally I found a good solution for my bill printing task and it is working properly for me.
This class provides the print service
public class PrinterService {
public PrintService getCheckPrintService(String printerName) {
PrintService ps = null;
DocFlavor doc_flavor = DocFlavor.STRING.TEXT_PLAIN;
PrintRequestAttributeSet attr_set =
new HashPrintRequestAttributeSet();
attr_set.add(new Copies(1));
attr_set.add(Sides.ONE_SIDED);
PrintService[] service = PrintServiceLookup.lookupPrintServices(doc_flavor, attr_set);
for (int i = 0; i < service.length; i++) {
System.out.println(service[i].getName());
if (service[i].getName().equals(printerName)) {
ps = service[i];
}
}
return ps;
}
}
This class demonstrates the bill printing task,
public class HelloWorldPrinter implements Printable {
@Override
public int print(Graphics graphics, PageFormat pageFormat, int pageIndex) throws PrinterException {
if (pageIndex > 0) { /* We have only one page, and 'page' is zero-based */
return NO_SUCH_PAGE;
}
Graphics2D g2d = (Graphics2D) graphics;
g2d.translate(pageFormat.getImageableX(), pageFormat.getImageableY());
//the String to print in multiple lines
//writing a semicolon (;) at the end of each sentence
String mText = "SHOP MA;"
+ "Pannampitiya;"
+ "----------------------------;"
+ "09-10-2012 harsha no: 001 ;"
+ "No Item Qty Price Amount ;"
+ "----------------------------;"
+ "1 Bread 1 50.00 50.00 ;"
+ "----------------------------;";
//Prepare the rendering
//split the String by the semicolon character
String[] bill = mText.split(";");
int y = 15;
Font f = new Font(Font.SANS_SERIF, Font.PLAIN, 8);
graphics.setFont(f);
//draw each String in a separate line
for (int i = 0; i < bill.length; i++) {
graphics.drawString(bill[i], 5, y);
y = y + 15;
}
/* tell the caller that this page is part of the printed document */
return PAGE_EXISTS;
}
public void pp() throws PrinterException {
PrinterService ps = new PrinterService();
//get the printer service by printer name
PrintService pss = ps.getCheckPrintService("Deskjet-1000-J110-series-2");
PrinterJob job = PrinterJob.getPrinterJob();
job.setPrintService(pss);
job.setPrintable(this);
try {
job.print();
} catch (PrinterException ex) {
ex.printStackTrace();
}
}
public static void main(String[] args) {
HelloWorldPrinter hwp = new HelloWorldPrinter();
try {
hwp.pp();
} catch (Exception e) {
e.printStackTrace();
}
}
}
Yes, just open the "Source" Tab in the dev-tools and navigate to the script you want to change . Make your adjustments directly in the dev tools window and then hit ctrl+s to save the script - know the new js will be used until you refresh the whole page.
Without favouring any particular naming choice, remember that a git repo can be cloned into any root directory of your choice:
git clone https://github.com/user/repo.git myDir
Here repo.git
would be cloned into the myDir
directory.
So even if your naming convention for a public repo ended up to be slightly incorrect, it would still be possible to fix it on the client side.
That is why, in a distributed environment where any client can do whatever he/she wants, there isn't really a naming convention for Git repo.
(except to reserve "xxx.git
" for bare form of the repo 'xxx
')
There might be naming convention for REST service (similar to "Are there any naming convention guidelines for REST APIs?"), but that is a separate issue.
I'm assuming what you want to do is run a command without an interface (possibly automatically?). On windows there are a number of options for what you are looking for:
Best: write your program as a windows service. These will start when no one logs into the server. They let you select the user account (which can be different than your own) and they will restart if they fail. These run all the time so you can automate tasks at specific times or on a regular schedule from within them. For more information on how to write a windows service you can read a tutorial online such as (http://msdn.microsoft.com/en-us/library/zt39148a(v=vs.110).aspx).
Better: Start the command and hide the window. Assuming the command is a DOS command you can use a VB or C# script for this. See here for more information. An example is:
Set objShell = WScript.CreateObject("WScript.Shell")
objShell.Run("C:\yourbatch.bat"), 0, True
You are still going to have to start the command manually or write a task to start the command. This is one of the biggest down falls of this strategy.
Hope that helps some!
You're almost there: it's NOW() - INTERVAL 1 DAY
In case if you are using node js, then this could be the possible solution
const express = require("express");
const app = express();
const server = app.listen(8080);
server.keepAliveTimeout = 61 * 1000;
There are various ways to achieve this. Here are three.
Map<String, String> map = new HashMap<String, String>();
map.put("key1", "value1");
map.put("key2", "value2");
map.put("key3", "value3");
System.out.println("using entrySet and toString");
for (Entry<String, String> entry : map.entrySet()) {
System.out.println(entry);
}
System.out.println();
System.out.println("using entrySet and manual string creation");
for (Entry<String, String> entry : map.entrySet()) {
System.out.println(entry.getKey() + "=" + entry.getValue());
}
System.out.println();
System.out.println("using keySet");
for (String key : map.keySet()) {
System.out.println(key + "=" + map.get(key));
}
System.out.println();
using entrySet and toString
key1=value1
key2=value2
key3=value3
using entrySet and manual string creation
key1=value1
key2=value2
key3=value3
using keySet
key1=value1
key2=value2
key3=value3
You can download image by Asyn task
use this class:
public class ImageDownloaderTask extends AsyncTask<String, Void, Bitmap> {
private final WeakReference<ImageView> imageViewReference;
private final MemoryCache memoryCache;
private final BrandItem brandCatogiriesItem;
private Context context;
private String url;
public ImageDownloaderTask(ImageView imageView, String url, Context context) {
imageViewReference = new WeakReference<ImageView>(imageView);
memoryCache = new MemoryCache();
brandCatogiriesItem = new BrandItem();
this.url = url;
this.context = context;
}
@Override
protected Bitmap doInBackground(String... params) {
return downloadBitmap(params[0]);
}
@Override
protected void onPostExecute(Bitmap bitmap) {
if (isCancelled()) {
bitmap = null;
}
if (imageViewReference != null) {
ImageView imageView = imageViewReference.get();
if (imageView != null) {
if (bitmap != null) {
memoryCache.put("1", bitmap);
brandCatogiriesItem.setUrl(url);
brandCatogiriesItem.setThumb(bitmap);
// BrandCatogiriesItem.saveLocalBrandOrCatogiries(context, brandCatogiriesItem);
imageView.setImageBitmap(bitmap);
} else {
Drawable placeholder = imageView.getContext().getResources().getDrawable(R.drawable.placeholder);
imageView.setImageDrawable(placeholder);
}
}
}
}
private Bitmap downloadBitmap(String url) {
HttpURLConnection urlConnection = null;
try {
URL uri = new URL(url);
urlConnection = (HttpURLConnection) uri.openConnection();
int statusCode = urlConnection.getResponseCode();
if (statusCode != HttpStatus.SC_OK) {
return null;
}
InputStream inputStream = urlConnection.getInputStream();
if (inputStream != null) {
Bitmap bitmap = BitmapFactory.decodeStream(inputStream);
return bitmap;
}
} catch (Exception e) {
Log.d("URLCONNECTIONERROR", e.toString());
if (urlConnection != null) {
urlConnection.disconnect();
}
Log.w("ImageDownloader", "Error downloading image from " + url);
} finally {
if (urlConnection != null) {
urlConnection.disconnect();
}
}
return null;
}
}
And call this like:
new ImageDownloaderTask(thumbImage, item.thumbnail, context).execute(item.thumbnail);
A simple way to achieve what you want:
import cv2
s_img = cv2.imread("smaller_image.png")
l_img = cv2.imread("larger_image.jpg")
x_offset=y_offset=50
l_img[y_offset:y_offset+s_img.shape[0], x_offset:x_offset+s_img.shape[1]] = s_img
I suppose you want to take care of the alpha channel too. Here is a quick and dirty way of doing so:
s_img = cv2.imread("smaller_image.png", -1)
y1, y2 = y_offset, y_offset + s_img.shape[0]
x1, x2 = x_offset, x_offset + s_img.shape[1]
alpha_s = s_img[:, :, 3] / 255.0
alpha_l = 1.0 - alpha_s
for c in range(0, 3):
l_img[y1:y2, x1:x2, c] = (alpha_s * s_img[:, :, c] +
alpha_l * l_img[y1:y2, x1:x2, c])
Use calc
:
.leftSide {_x000D_
float: left;_x000D_
width: 50px;_x000D_
background-color: green;_x000D_
}_x000D_
.rightSide {_x000D_
float: left;_x000D_
width: calc(100% - 50px);_x000D_
background-color: red;_x000D_
}
_x000D_
<div style="width:200px">_x000D_
<div class="leftSide">a</div>_x000D_
<div class="rightSide">b</div>_x000D_
</div>
_x000D_
The problem with this is that all widths must be explicitly defined, either as a value(px and em work fine), or as a percent of something explicitly defined itself.
When using JBOSS Server, double click on the server:
Go to "Open Launch Configuration"
Then change min and max memory sizes (like 1G, 1m):
The Set statement is only used for object variables (like Range
, Cell
or Worksheet
in Excel), while the simple equal sign '=' is used for elementary datatypes like Integer
. You can find a good explanation for when to use set here.
The other problem is, that your variable g1val
isn't actually declared as Integer
, but has the type Variant
. This is because the Dim statement doesn't work the way you would expect it, here (see example below). The variable has to be followed by its type right away, otherwise its type will default to Variant
. You can only shorten your Dim statement this way:
Dim intColumn As Integer, intRow As Integer 'This creates two integers
For this reason, you will see the "Empty" instead of the expected "0" in the Watches window.
Try this example to understand the difference:
Sub Dimming()
Dim thisBecomesVariant, thisIsAnInteger As Integer
Dim integerOne As Integer, integerTwo As Integer
MsgBox TypeName(thisBecomesVariant) 'Will display "Empty"
MsgBox TypeName(thisIsAnInteger ) 'Will display "Integer"
MsgBox TypeName(integerOne ) 'Will display "Integer"
MsgBox TypeName(integerTwo ) 'Will display "Integer"
'By assigning an Integer value to a Variant it becomes Integer, too
thisBecomesVariant = 0
MsgBox TypeName(thisBecomesVariant) 'Will display "Integer"
End Sub
Two further notices on your code:
First remark: Instead of writing
'If g1val is bigger than the value in the current cell
If g1val > Cells(33, i).Value Then
g1val = g1val 'Don't change g1val
Else
g1val = Cells(33, i).Value 'Otherwise set g1val to the cell's value
End If
you could simply write
'If g1val is smaller or equal than the value in the current cell
If g1val <= Cells(33, i).Value Then
g1val = Cells(33, i).Value 'Set g1val to the cell's value
End If
Since you don't want to change g1val
in the other case.
Second remark: I encourage you to use Option Explicit when programming, to prevent typos in your program. You will then have to declare all variables and the compiler will give you a warning if a variable is unknown.
Stealing from Philip Roberts here:
Two examples:
1. Doubling all numbers in an array
Imperatively:
var numbers = [1,2,3,4,5]
var doubled = []
for(var i = 0; i < numbers.length; i++) {
var newNumber = numbers[i] * 2
doubled.push(newNumber)
}
console.log(doubled) //=> [2,4,6,8,10]
Declaratively:
var numbers = [1,2,3,4,5]
var doubled = numbers.map(function(n) {
return n * 2
})
console.log(doubled) //=> [2,4,6,8,10]
2. Summing all items in a list
Imperatively
var numbers = [1,2,3,4,5]
var total = 0
for(var i = 0; i < numbers.length; i++) {
total += numbers[i]
}
console.log(total) //=> 15
Declaratively
var numbers = [1,2,3,4,5]
var total = numbers.reduce(function(sum, n) {
return sum + n
});
console.log(total) //=> 15
Note how the imperative examples involve creating a new variable, mutating it, and returning that new value (i.e., how to make something happen), whereas the declarative examples execute on a given input and return the new value based on the initial input (i.e., what we want to happen).
Just for the record: for me it turned out that it was the gem called 'mysql' ... obviously this is working with US-ASCII 8 bit by default. So changing it to the gem called mysql2 (the 2 is the important point here) solved all of my issues.
I looked @ the gem list posted above - Michael Koper has obviously mysql2 installed but I posted this in case someone has this issue as well .. (took me some time to figure out).
If you dislike this answer please comment and I will delete it.
P.S: German umlauts (ä,ö and ü) screwed it out with mysql
My path of -javaagent argument was having Spacial characters like '&'. I placed the Lambok jar in different place and gave the path to that place. It worked for me.
previously it was
-javaagent:C:\Software & Tool\lambok.jar
i changed it to
-javaagent:C:\Labmok\lambok.jar
[Update: Although I discovered this trick independently, I’ve since learned that Thierry Koblentz beat me to it. You can find his 2009 article on A List Apart. Credit where credit is due.]
I know this is an old question, but I encountered a similar problem that I did solve only with CSS. Here is my blog post that discusses the solution. Included in the post is a live example. Code is reposted below.
#container {
display: inline-block;
position: relative;
width: 50%;
}
#dummy {
margin-top: 75%;
/* 4:3 aspect ratio */
}
#element {
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
background-color: silver/* show me! */
}
_x000D_
<div id="container">
<div id="dummy"></div>
<div id="element">
some text
</div>
</div>
_x000D_
using uncontrolled fields:
export default class MyComponent extends React.Component {
onSubmit(e) {
e.preventDefault();
console.log(e.target.neededField.value);
}
render(){
return (
...
<form onSubmit={this.onSubmit} className="form-horizontal">
...
<input type="text" name="neededField" className="form-control" ref={(c) => this.title = c} name="title" />
...
</form>
...
<button type="button" className="btn">Save</button>
...
);
}
};
I assume your talking about windows forms:
To display your form use the Show() method:
Form form2 = new Form();
form2.Show();
to close the form use Close():
form2.Close();
Create a page which contains two links- one at the top and one at the bottom. On clicking the top link, the page has to scroll down to the bottom of the page where bottom link is present. On clicking the bottom link, the page has to scroll up to the top of the page.
MySQL, SQL Server, PostgreSQL, SQLite support using the percent sign as the modulus:
WHERE column % 2 = 1
For Oracle, you have to use the MOD function:
WHERE MOD(column, 2) = 1
you could try in this way: get the integer value of the double, subtract this from the original double value, define a rounding range and tests if the absolute number of the new double value(without the integer part) is larger or smaller than your defined range. if it is smaller you can intend it it is an integer value. Example:
public final double testRange = 0.2;
public static boolean doubleIsInteger(double d){
int i = (int)d;
double abs = Math.abs(d-i);
return abs <= testRange;
}
If you assign to d the value 33.15 the method return true. To have better results you can assign lower values to testRange (as 0.0002) at your discretion.
Unless I'm badly mistaken libmagic
or -lmagic
is not the same library as ImageMagick. You state that you want ImageMagick.
ImageMagick comes with a utility to supply all appropriate options to the compiler.
Ex:
g++ program.cpp `Magick++-config --cppflags --cxxflags --ldflags --libs` -o "prog"

$('.options').not(elem).hide('fast');
$('.SettingsTitle').not($(this)).parent().children("h3").children("a.toggle").children("img").attr('src', closeMenuImg);
elem.toggle('fast');
var targetImg = $(this).parent().children("h3").children("a.toggle").children("img").attr('src') === closeMenuImg ? openMenuImg : closeMenuImg;
$(this).parent().children("h3").children("a.toggle").children("img").attr('src', targetImg);
});
});
Without jQuery updated
document.querySelectorAll('.testimonial').forEach(function (element, index) {_x000D_

To change the color via:
Put these styles in your stylesheet after the bootstrap styles:
.modal-backdrop {
background-color: red;
}
Changes the bootstrap-variables to:
@modal-backdrop-bg: red;
Changes the bootstrap-variables to:
$modal-backdrop-bg: red;
Change @modal-backdrop-bg
to your desired color:
You can also remove the backdrop via Javascript or by setting the color to transparent

You can functionalize this however you like.
In Loops, I always prefer to use the Cells
class, using the R1C1 reference method, like this:
Cells(rr, col).Formula = ...
This allows me to quickly and easily loop over a Range of cells easily:
Dim r As Long
Dim c As Long
c = GetTargetColumn() ' Or you could just set this manually, like: c = 1
With Sheet1 ' <-- You should always qualify a range with a sheet!
For r = 1 To 10 ' Or 1 To (Ubound(MyListOfStuff) + 1)
' Here we're looping over all the cells in rows 1 to 10, in Column "c"
.Cells(r, c).Value = MyListOfStuff(r)
'---- or ----
'...to easily copy from one place to another (even with an offset of rows and columns)
.Cells(r, c).Value = Sheet2.Cells(r + 3, 17).Value
Next r
End With
What about
Game.status[0][0] or Game.status[0]["0"] ?
Does one of these work?
PS: What you have in your question is a Javascript Object, not JSON. JSON is the 'string' version of a Javascript Object.
There's no difference between list implementations in both of your examples. There's however a difference in a way you can further use variable myList in your code.
When you define your list as:
List myList = new ArrayList();
you can only call methods and reference members that are defined in the List interface. If you define it as:
ArrayList myList = new ArrayList();
you'll be able to invoke ArrayList-specific methods and use ArrayList-specific members in addition to those whose definitions are inherited from List.
Nevertheless, when you call a method of a List interface in the first example, which was implemented in ArrayList, the method from ArrayList will be called (because the List interface doesn't implement any methods).
That's called polymorphism. You can read up on it.
I have the same issue, I solved the problem, just disabled
"BranchCache Service" in services.
Somehow windows updates, this service is triggered in startup, and uses 80 ports. When you check via netstat you could see the system is used this but couldnt understand which service is used.
based on examples above and examples found on other sites, I created a generic procedure and some examples.

How to show uncommitted changes in Git
The command you are looking for is git diff
.
git diff
- Show changes between commits, commit and working tree, etc
Here are some of the options it expose which you can use
git diff
(no parameters)
Print out differences between your working directory and the index.
git diff --cached
:
Print out differences between the index and HEAD (current commit).
git diff HEAD
:
Print out differences between your working directory and the HEAD.
git diff --name-only
Show only names of changed files.
git diff --name-status
Show only names and status of changed files.
git diff --color-words
Word by word diff instead of line by line.
Here is a sample of the output for git diff --color-words
:
Like others have already said, it's not immediately obvious what you're asking. I'm going to assume that you want to start a process and then perform another action when the process "is ready".
Of course, the "is ready" is the tricky bit. Depending on what you're needs are, you may find that simply waiting is sufficient. However, if you need a more robust solution, you can consider using a named Mutex to control the control flow between your two processes.
For example, in your main process, you might create a named mutex and start a thread or task which will wait. Then, you can start the 2nd process. When that process decides that "it is ready", it can open the named mutex (you have to use the same name, of course) and signal to the first process.
EDIT: Please check out Andy's answer as his answer came first and this is solely an extension of his
I know this is an old question, but I think it's worth it to include Array.prototype.sort()
.
Here's an example from MDN along with the link
var numbers = [4, 2, 5, 1, 3];
numbers.sort(function(a, b) {
return a - b;
});
console.log(numbers);
// [1, 2, 3, 4, 5]
Luckily it doesn't only work with numbers:
arr.sort([compareFunction])
compareFunction
Specifies a function that defines the sort order. If omitted, the array is sorted according to each character's Unicode code point value, according to the string conversion of each element.
I noticed that you're ordering them by first name:
let playlist = [
{artist:"Herbie Hancock", title:"Thrust"},
{artist:"Lalo Schifrin", title:"Shifting Gears"},
{artist:"Faze-O", title:"Riding High"}
];
// sort by name
playlist.sort((a, b) => {
if(a.artist < b.artist) { return -1; }
if(a.artist > b.artist) { return 1; }
// else names must be equal
return 0;
});
note that if you wanted to order them by last name you would have to either have a key for both first_name
& last_name
or do some regex magic, which I can't do XD
Hope that helps :)
Playing with JavaScript in an HTA I had no luck with a driver={SQL Server};...
connection string, but a named DSN was OK :
I set up TestDSN and it tested OK, and then var strConn= "DSN=TestDSN";
worked, so I carried on experimenting for my in-house testing and learning purposes.
Our server has several instances running, e.g. server1\dev and server1\Test which made things slightly more tricky as I managed to waste some time forgetting to escape the \
as \\
:)
After some dead-ends with server=server1;instanceName=dev
in the connection strings, I eventually got this one to work :
var strConn= "Provider=SQLOLEDB;Data Source=server1\\dev;Trusted_Connection=Yes;Initial Catalog=MyDatabase;"
Using Windows credentials rather than supplying a user/pwd, I found an interesting diversion was discovering the subtleties of Integrated Security = true
v Integrated Security = SSPI
v Trusted_Connection=Yes
- see Difference between Integrated Security = True and Integrated Security = SSPI
Beware that RecordCount will come back as -1
if using the default adOpenForwardOnly type. If you're working with small result sets and/or don't mind the whole lot in memory at once, use rs.Open(strQuery, objConnection, 3);
(3=adOpenStatic) and this gives a valid rs.RecordCount
You can use dev tools profiler.
console.time('Timer name');
//do critical time stuff
console.timeEnd('Timer name');
"Timer name" must be the same. You can use multiple instances of timer with different names.
One more possibility --
Make sure you're trying to open the same IP address as where you're listening. My server app was listening to the host machine's IP address using IPv6, but the client was attempting to connect on the host machine's IPv4 address.
You can use the input
Javascript event in jQuery like this:
$('#inputDatabaseName').on('input',function(e){
alert('Changed!')
});
In pure JavaScript:
document.querySelector("input").addEventListener("change",function () {
alert("Input Changed");
})
Or like this:
<input id="inputDatabaseName" onchange="youFunction();"
onkeyup="this.onchange();" onpaste="this.onchange();" oninput="this.onchange();"/>
