I had the same problem as Andre. There does not seem to be a direct solution, but a CAST in the query that generates the data fixes the problem as long as you can live within the restrictions of SMALLDATETIME. In the following query, the first column does not format correctly in Excel, the second does.
SELECT GETDATE(), CAST(GETDATE() AS SMALLDATETIME)
Perhaps the fractional part of the seconds in DATETIME and DATETIME2 confuses Excel.
You don't need JavaScript for this.
Some CSS would do it. Here is an example:
<html>_x000D_
<style type="text/css">_x000D_
.section { background:#ccc; }_x000D_
.layer { background:#ddd; }_x000D_
.section:hover img { border:2px solid #333; }_x000D_
.section:hover .layer { border:2px solid #F90; }_x000D_
</style>_x000D_
</head>_x000D_
<body>_x000D_
<div class="section">_x000D_
<img src="myImage.jpg" />_x000D_
<div class="layer">Lorem Ipsum</div>_x000D_
</div>_x000D_
</body>_x000D_
</html>
_x000D_
All I know is I wanted the IP address beginning with 192.168.
. This code will give you that:
function getLocalIp() {
const os = require('os');
for(let addresses of Object.values(os.networkInterfaces())) {
for(let add of addresses) {
if(add.address.startsWith('192.168.')) {
return add.address;
}
}
}
}
Of course you can just change the numbers if you're looking for a different one.
You have by default the static
endpoint for static files. Also Flask
application has the following arguments:
static_url_path
: can be used to specify a different path for the static files on the web. Defaults to the name of the static_folder
folder.
static_folder
: the folder with static files that should be served at static_url_path
. Defaults to the 'static' folder in the root path of the application.
It means that the filename
argument will take a relative path to your file in static_folder
and convert it to a relative path combined with static_url_default
:
url_for('static', filename='path/to/file')
will convert the file path from static_folder/path/to/file
to the url path static_url_default/path/to/file
.
So if you want to get files from the static/bootstrap
folder you use this code:
<link rel="stylesheet" type="text/css" href="{{ url_for('static', filename='bootstrap/bootstrap.min.css') }}">
Which will be converted to (using default settings):
<link rel="stylesheet" type="text/css" href="static/bootstrap/bootstrap.min.css">
Also look at url_for
documentation.
Spring security's @WithMockUser
and hamcrest's containsString
matcher makes for a simple and elegant solution:
@Test
@WithMockUser(roles = "USER")
public void loginWithRoleUserThenExpectUserSpecificContent() throws Exception {
mockMvc.perform(get("/index"))
.andExpect(status().isOk())
.andExpect(content().string(containsString("This content is only shown to users.")));
}
The most important one is that importing java.awt.*
can make your program incompatible with a future Java version:
Suppose that you have a class named "ABC", you're using JDK 8 and you import java.util.*
. Now, suppose that Java 9 comes out, and it has a new class in package java.util
that by coincidence also happens to be called "ABC". Your program now will not compile on Java 9, because the compiler doesn't know if with the name "ABC" you mean your own class or the new class in java.awt
.
You won't have that problem when you import only those classes explicitly from java.awt
that you actually use.

This works reliably for me. Cell borders and height added for effect and clarity:
<table>_x000D_
<tr>_x000D_
<td style="text-align:right; border: thin solid; height:50px">Some label:</td>_x000D_
<td style="border: thin solid;">_x000D_

You could look at "XpathNavigator.Evaluate" I have used this to process mathematical expressions for my GridView and it works fine for me.
Here is the code I used for my program:
public static double Evaluate(string expression)
{
return (double)new System.Xml.XPath.XPathDocument
(new StringReader("<r/>")).CreateNavigator().Evaluate
(string.Format("number({0})", new
System.Text.RegularExpressions.Regex(@"([\+\-\*])")
.Replace(expression, " ${1} ")
.Replace("/", " div ")
.Replace("%", " mod ")));
}
I am doing some large calculations which involves the mysql connection to stay long time and with heavy data. i was facing this "Mysql go away issue". So i tried t optimize the queries but that doen't helped me then i increased the mysql variables limit which is set to a lower value by default.
wait_timeout max_allowed_packet
To the limit what ever suits to you it should be the Any Number * 1024(Bytes). you can login to terminal using 'mysql -u username - p' command and can check and change for these variable limits.
The xlsxwriter
library is great for creating .xlsx
files. The following snippet generates an .xlsx
file from a list of dicts while stating the order and the displayed names:
from xlsxwriter import Workbook
def create_xlsx_file(file_path: str, headers: dict, items: list):
with Workbook(file_path) as workbook:
worksheet = workbook.add_worksheet()
worksheet.write_row(row=0, col=0, data=headers.values())
header_keys = list(headers.keys())
for index, item in enumerate(items):
row = map(lambda field_id: item.get(field_id, ''), header_keys)
worksheet.write_row(row=index + 1, col=0, data=row)
headers = {
'id': 'User Id',
'name': 'Full Name',
'rating': 'Rating',
}
items = [
{'id': 1, 'name': "Ilir Meta", 'rating': 0.06},
{'id': 2, 'name': "Abdelmadjid Tebboune", 'rating': 4.0},
{'id': 3, 'name': "Alexander Lukashenko", 'rating': 3.1},
{'id': 4, 'name': "Miguel Díaz-Canel", 'rating': 0.32}
]
create_xlsx_file("my-xlsx-file.xlsx", headers, items)
Note 1 - I'm purposely not answering to the exact case the OP presented. Instead, I'm presenting a more generic solution IMHO most visitors seek. This question's title is well-indexed in search engines and tracks lots of traffic
Note 2 - If you're not using Python3.6 or newer, consider using
OrderedDict
inheaders
. Before Python3.6 the order indict
was not preserved.
For TypeScript 2.0 it would look like this:
MyStore.ts
export namespace Store {
export type Login = { isLoggedIn: boolean }
export type All = {
login: Login
}
}
import { reducers } from '../Reducers'
import * as Redux from 'redux'
const reduxStore: Redux.Store<Store.All> = Redux.createStore(reducers)
export default reduxStore;
MyClient.tsx
import reduxStore from "../Store";
{reduxStore.dispatch(...)}
int[] numbers = {1,2,3,4,5,3,6,4,7,8,9,1,0 };
var nonRepeats = (from n in numbers select n).Distinct();
foreach (var d in nonRepeats)
{
Response.Write(d);
}
OUTPUT
1234567890
If you're going to have a lot of inheritence (that's the case here) I suggest you to pass all parameters using **kwargs
, and then pop
them right after you use them (unless you need them in upper classes).
class First(object):
def __init__(self, *args, **kwargs):
self.first_arg = kwargs.pop('first_arg')
super(First, self).__init__(*args, **kwargs)
class Second(First):
def __init__(self, *args, **kwargs):
self.second_arg = kwargs.pop('second_arg')
super(Second, self).__init__(*args, **kwargs)
class Third(Second):
def __init__(self, *args, **kwargs):
self.third_arg = kwargs.pop('third_arg')
super(Third, self).__init__(*args, **kwargs)
This is the simplest way to solve those kind of problems.
third = Third(first_arg=1, second_arg=2, third_arg=3)
You can use the strip()
function to remove trailing (and leading) whitespace; passing it an argument will let you specify which whitespace:
for i in range(len(lists)):
grades.append(lists[i].strip('\n'))
It looks like you can just simplify the whole block though, since if your file stores one ID per line grades
is just lists
with newlines stripped:
lists = files.readlines()
grades = []
for i in range(len(lists)):
grades.append(lists[i].split(","))
grades = [x.strip() for x in files.readlines()]
(the above is a list comprehension)
Finally, you can loop over a list directly, instead of using an index:
for i in range(len(grades)):
# do something with grades[i]
for thisGrade in grades:
# do something with thisGrade
I would like to add that there is a Parallel class with ForEach function built in that can be used for this purpose.
I always use the time-stamp - so its not possible, that the file exists already:
import os
import shutil
import datetime
now = str(datetime.datetime.now())[:19]
now = now.replace(":","_")
src_dir="C:\\Users\\Asus\\Desktop\\Versand Verwaltung\\Versand.xlsx"
dst_dir="C:\\Users\\Asus\\Desktop\\Versand Verwaltung\\Versand_"+str(now)+".xlsx"
shutil.copy(src_dir,dst_dir)

Check your build types of each project under project properties - I bet one or the other will be set to build against .NET XX - Client Profile
.
With inconsistent versions, specifically with one being Client Profile
and the other not, then it works at design time but fails at compile time. A real gotcha.
There is something funny going on in Visual Studio 2010 for me, which keeps setting projects seemingly randomly to Client Profile
, sometimes when I create a project, and sometimes a few days later. Probably some keyboard shortcut I'm accidentally hitting...
Give your input an ID and use the attr
method:
var name = $("#id").attr("name");
I had a similar problem to the OP. Then I saw the answer from @Urs Marian which helped a lot. But additionally what I was looking for is, when there are multiple values in a column and they will be grouped, how I can get the last submitted value (e.g. ordered by a date/id column).
Example:
We have following table structure:
CREATE TABLE tablename(
[msgid] [int] NOT NULL,
[userid] [int] NOT NULL,
[username] [varchar](70) NOT NULL,
[message] [varchar](5000) NOT NULL
)
Now there are at least two datasets in the table:
+-------+--------+----------+---------+
| msgid | userid | username | message |
+-------+--------+----------+---------+
| 1 | 1 | userA | hello |
| 2 | 1 | userB | world |
+-------+--------+----------+---------+
Therefore following SQL script does work (checked on MSSQL) to group it, also if the same userid has different username values. In the example below, the username with the highest msgid will be shown:
SELECT m.userid,
(select top 1 username from table where userid = m.userid order by msgid desc) as username,
count(*) as messages
FROM tablename m
GROUP BY m.userid
ORDER BY count(*) DESC
Another approach that may be more readable is simple type conversion. I've added a replacement function to cover instances where people may enter European decimals:
>>> for possibility in "Current Level: -13.2 db or 14,2 or 3".split():
... try:
... str(float(possibility.replace(',', '.')))
... except ValueError:
... pass
'-13.2'
'14.2'
'3.0'
This has disadvantages too however. If someone types in "1,000", this will be converted to 1. Also, it assumes that people will be inputting with whitespace between words. This is not the case with other languages, such as Chinese.
your sql Statement creating code may be like
statement = connection.createStatement();
To solve "com.microsoft.sqlserver.jdbc.SQLServerException: The requested operation is not supported on forward only result sets" exception change above code with
statement = connection.createStatement(
ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_READ_ONLY);
After above change you can use
int size = 0;
try {
resultSet.last();
size = resultSet.getRow();
resultSet.beforeFirst();
}
catch(Exception ex) {
return 0;
}
return size;
to get row count
This works and I need to set the token only once in my app.js
:
axios.defaults.headers.common = {
'Authorization': 'Bearer ' + token
};
Then I can make requests in my components without setting the header again.
"axios": "^0.19.0",
Now there is special method - get_fields()
>>> from django.contrib.auth.models import User
>>> User._meta.get_fields()
It accepts two parameters that can be used to control which fields are returned:
include_parents
True by default. Recursively includes fields defined on parent classes. If set to False, get_fields() will only search for fields declared directly on the current model. Fields from models that directly inherit from abstract models or proxy classes are considered to be local, not on the parent.
include_hidden
False by default. If set to True, get_fields() will include fields that are used to back other field’s functionality. This will also include any fields that have a related_name (such as ManyToManyField, or ForeignKey) that start with a “+”
This below code just show the very basic use of delegate concept .. you name the variable and class as per your requirement.
First you need to declare a protocol:
Let's call it MyFirstControllerDelegate.h
@protocol MyFirstControllerDelegate
- (void) FunctionOne: (MyDataOne*) dataOne;
- (void) FunctionTwo: (MyDatatwo*) dataTwo;
@end
Import MyFirstControllerDelegate.h file and confirm your FirstController with protocol MyFirstControllerDelegate
#import "MyFirstControllerDelegate.h"
@interface FirstController : UIViewController<MyFirstControllerDelegate>
{
}
@end
In the implementation file, you need to implement both functions of protocol:
@implementation FirstController
- (void) FunctionOne: (MyDataOne*) dataOne
{
//Put your finction code here
}
- (void) FunctionTwo: (MyDatatwo*) dataTwo
{
//Put your finction code here
}
//Call below function from your code
-(void) CreateSecondController
{
SecondController *mySecondController = [SecondController alloc] initWithSomeData:.];
//..... push second controller into navigation stack
mySecondController.delegate = self ;
[mySecondController release];
}
@end
in your SecondController:
@interface SecondController:<UIViewController>
{
id <MyFirstControllerDelegate> delegate;
}
@property (nonatomic,assign) id <MyFirstControllerDelegate> delegate;
@end
In the implementation file of SecondController.
@implementation SecondController
@synthesize delegate;
//Call below two function on self.
-(void) SendOneDataToFirstController
{
[delegate FunctionOne:myDataOne];
}
-(void) SendSecondDataToFirstController
{
[delegate FunctionTwo:myDataSecond];
}
@end
Here is the wiki article on delegate.
You have to create a new customer object in every iteration and then add that newly created object into the ArrayList at the lase of your iteration.
My answer will scroll even when overflow:hidden;
, using jQuery:
For example, scroll horizontally with the mouse wheel:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script type='text/javascript' src='/js/jquery.mousewheel.min.js'></script>
<script type="text/javascript">
$(function() {
$("YourSelector").mousewheel(function(event, delta) {
this.scrollLeft -= (delta * 30);
event.preventDefault();
});
});
</script>
Replace Your onOptionsItemSelected
as:
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case OK_MENU_ITEM:
startActivity(new Intent(DashboardActivity.this, SettingActivity.class));
break;
// You can handle other cases Here.
default:
super.onOptionsItemSelected(item);
}
}
Here, I want to navigate from DashboardActivity
to SettingActivity
.
For a virtual function you need to provide implementation in the base class. However derived class can override this implementation with its own implementation. Normally , for pure virtual functions implementation is not provided. You can make a function pure virtual with =0
at the end of function declaration. Also, a class containing a pure virtual function is abstract i.e. you can not create a object of this class.
Since you are in a controller, the action method is given a Request
parameter.
You can access all POST data with $request->request->all();
.
This returns a key-value pair array.
When using GET requests you access data using $request->query->all();
Wrong method was used for errors, here is the working code:
BufferedReader br = null;
if (100 <= conn.getResponseCode() && conn.getResponseCode() <= 399) {
br = new BufferedReader(new InputStreamReader(conn.getInputStream()));
} else {
br = new BufferedReader(new InputStreamReader(conn.getErrorStream()));
}
git log -n 1 [branch_name]
branch_name
(may be remote or local branch) is optional. Without branch_name
, it will show the latest commit on the current branch.
For example:
git log -n 1
git log -n 1 origin/master
git log -n 1 some_local_branch
git log -n 1 --pretty=format:"%H" #To get only hash value of commit
The obvious thing to do is read the documentation.
But to help: substr($str, $start, $end);
$str
is your text
$start
is the character index to begin at. In your case, it is likely 0 which means the very beginning.
$end
is where to truncate at. Suppose you wanted to end at 15 characters, for example. You would write it like this:
<?php
$text = "long text that should be truncated";
echo substr($text, 0, 15);
?>
and you would get this:
long text that
makes sense?
EDIT
The link you gave is a function to find the last white space after chopping text to a desired length so you don't cut off in the middle of a word. However, it is missing one important thing - the desired length to be passed to the function instead of always assuming you want it to be 25 characters. So here's the updated version:
function truncate($text, $chars = 25) {
if (strlen($text) <= $chars) {
return $text;
}
$text = $text." ";
$text = substr($text,0,$chars);
$text = substr($text,0,strrpos($text,' '));
$text = $text."...";
return $text;
}
So in your case you would paste this function into the functions.php file and call it like this in your page:
$post = the_post();
echo truncate($post, 100);
This will chop your post down to the last occurrence of a white space before or equal to 100 characters. Obviously you can pass any number instead of 100. Whatever you need.
In your example, you prepended your source string with AccountKey=
but not your target string.
$c = $c -replace 'AccountKey=eKkij32jGEIYIEqAR5RjkKgf4OTiMO6SAyF68HsR/Zd/KXoKvSdjlUiiWyVV2+OUFOrVsd7jrzhldJPmfBBpQA==','AccountKey=DdOegAhDmLdsou6Ms6nPtP37bdw6EcXucuT47lf9kfClA6PjGTe3CfN+WVBJNWzqcQpWtZf10tgFhKrnN48lXA=='
By not including that in the target string, the resulting string will remove AccountKey=
instead of replacing it. You correctly do this with the AccountName=
example, which seems to support this conclusion since it is not giving you any problems. If you really mean to have that prepended, then this may resolve your issue.
If you have some process listening on port 8080 then you can always configure tomcat to listen on a different port. To change the listener port by editing your server.xml
located under tomcat server conf
directory.
Search for Connector port="8080"
in server.xml and change the port number to some other port.
Here is how a UTF8 text file can be read from a zip archive into a string variable (.NET Framework 4.5 and up):
string zipFileFullPath = "{{TypeYourZipFileFullPathHere}}";
string targetFileName = "{{TypeYourTargetFileNameHere}}";
string text = new string(
(new System.IO.StreamReader(
System.IO.Compression.ZipFile.OpenRead(zipFileFullPath)
.Entries.Where(x => x.Name.Equals(targetFileName,
StringComparison.InvariantCulture))
.FirstOrDefault()
.Open(), Encoding.UTF8)
.ReadToEnd())
.ToArray());
check that if file is selected or not
if (document.myform.elements["filefield"].value == "")
{
alert("You forgot to attach file!");
document.myform.elements["filefield"].focus();
return false;
}
check the file extension
var res_field = document.myform.elements["filefield"].value;
var extension = res_field.substr(res_field.lastIndexOf('.') + 1).toLowerCase();
var allowedExtensions = ['doc', 'docx', 'txt', 'pdf', 'rtf'];
if (res_field.length > 0)
{
if (allowedExtensions.indexOf(extension) === -1)
{
alert('Invalid file Format. Only ' + allowedExtensions.join(', ') + ' are allowed.');
return false;
}
}
From jQuery:
Set the date to highlight on first opening if the field is blank. Specify either an actual date via a Date object or as a string in the current dateFormat, or a number of days from today (e.g. +7) or a string of values and periods ('y' for years, 'm' for months, 'w' for weeks, 'd' for days, e.g. '+1m +7d'), or null for today.
Code examples
Initialize a datepicker with the defaultDate option specified.
$(".selector").datepicker({ defaultDate: +7 });
Get or set the defaultDate option, after init.
//getter
var defaultDate = $(".selector").datepicker("option", "defaultDate");
//setter
$(".selector").datepicker("option", "defaultDate", +7);
After the datepicker is intialized you should also be able to set the date with:
$(/*selector*/).datepicker("setDate" , date)
Are you using php 5.4 on your local? the render line is using the new way of initializing arrays. Try replacing ["title" => "Welcome "]
with array("title" => "Welcome ")
<form name="loginform" onsubmit="validateForm()">
instead of putting the onsubmit on the actual input button
@Transactional =javax.transaction.Transactional
. Put it just beside @Repository
.
its better to use the Dependency than to attache it to the class.
public function add_question(Request $request)
{
return Request::all();
}
or if you prefer using input variable use
public function add_question(Request $input)
{
return $input::all();
}
you can now use the global request method provided by laravel
request()
for example to get the first_name of a form input.
request()->first_name
// or
request('first_name')
Location permission privacy change in Android 10 or Android Q.
We have to define additional ACCESS_BACKGROUND_LOCATION
permission if user wants to access their current location in background so user needs to granted permission runtime also in requestPermission()
If we are using lower than Android 10 device then ACCESS_BACKGROUND_LOCATION
permission allow automatically with ACCESS_FINE_LOCATION
or ACCESS_COARSE_LOCATION
permission
This tabular format might be easy to understand what if we don't specify ACCESS_BACKGROUND_LOCATION
in manifest file.

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

This post is high up when you google that error message, which I got when installing security patch KB4505224 on SQL Server 2017 Express i.e. None of the above worked for me, but did consume several hours trying.

And all was well.
Since the image is a linux, one thing to check is to make sure any shell scripts used in the container have unix line endings. If they have a ^M at the end then they are windows line endings. One way to fix them is with dos2unix on /usr/local/start-all.sh to convert them from windows to unix. Running the docker in interactive mode can help figure out other problems. You could have a file name typo or something. see https://en.wikipedia.org/wiki/Newline
Another way is to use the object tag. This works on Chrome, IE, Firefox, Safari and Opera.
<object data="html/stuff_to_include.html">
Your browser doesn’t support the object tag.
</object>

To my knowledge, no.
Circumstantial indications from $LC_CTYPE
, locale
and such might seem alluring, but these are completely separated from the encoding the terminal application (actually an emulator) happens to be using when displaying characters on the screen.
They only way to detect encoding for sure is to output something only present in the encoding, e.g. ä
, take a screenshot, analyze that image and check if the output character is correct.
So no, it's not possible, sadly.
SQL: show full processlist;
This is what the MySQL Workbench does.
set(A)-set(subset_of_A)
gives your the intended result set, but it won't retain the original order. The following is order preserving:
[a for a in A if not a in subset_of_A]
I was looking for something similar, and here's what I came up with:
My situation is one where I have an active web tree and I was trying to create a remote repository for it without moving any of the files in the current web tree. Here's what I did:
git init
git clone --bare /path/to/web/repo
[remote "origin"]
section.[remote "origin"]
section to .git/config in the web tree pointing to the new remote repo.Very informative answer from @stej, but here is a short answer: Among other options, you have 3 simple options to format [System.DateTime] stored in a variable:
Pass the variable to the Get-Date cmdlet:
Get-Date -Format "HH:mm" $date
Use toString() method:
$date.ToString("HH:mm")
Use Composite formatting:
"{0:HH:mm}" -f $date
In my case, this was caused by custom manifest entries added by the maven-jar-plugin.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.6</version>
<configuration>
<archive>
<index>true</index>

</manifest>
<manifestEntries>
<git>${buildNumber}</git>
<build-time>${timestamp}</build-time>
</manifestEntries>
</archive>
</configuration>
</plugin>
Removing the following entries fixed the problem
<index>true</index>

<addClasspath>true</addClasspath>

You are using two WHERE
clauses but only one is allowed. Use it like this:
SELECT table1.f_id FROM table1
INNER JOIN table2 ON table2.f_id = table1.f_id
WHERE
table1.f_com_id = '430'
AND table1.f_status = 'Submitted'
AND table2.f_type = 'InProcess'
ChronoUnit.between
Use instances of ChronoUnit
to calculate amount of time in different units (days,months, seconds).
For Example:
ChronoUnit.DAYS.between(startDate,endDate)
You could do something like this
public abstract MyAbstractClass {
@Autowire
private MyMock myMock;
protected String sayHello() {
return myMock.getHello() + ", " + getName();
}
public abstract String getName();
}
// this is your JUnit test
public class MyAbstractClassTest extends MyAbstractClass {
@Mock
private MyMock myMock;
@InjectMocks
private MyAbstractClass thiz = this;
private String myName = null;
@Override
public String getName() {
return myName;
}
@Test
public void testSayHello() {
myName = "Johnny"
when(myMock.getHello()).thenReturn("Hello");
String result = sayHello();
assertEquals("Hello, Johnny", result);
}
}
You don't need any plugin to do so. For instance, if you code JAVA, you can erase trailing whitespaces configuring save actions:
Eclipse 3.6
Preferences -> Java -> Editors -> Save Actions -> Check Perform the selected actions on save -> Check Additional actions -> Click the Configure.. button.
In the Code organizing tab, check Remove trailing whitespace
replace operates on a specific string, so you need to call it like this
removeSpecialChars = z.replace("!@#$%^&*()[]{};:,./<>?\|`~-=_+", " ")
but this is probably not what you need, since this will look for a single string containing all that characters in the same order. you can do it with a regexp, as Danny Michaud pointed out.
as a side note, you might want to look for BeautifulSoup, which is a library for parsing messy HTML formatted text like what you usually get from scaping websites.
git log --numstat just gives you only the numbers
There is a method public void setOnScrollListener (RecyclerView.OnScrollListener listener)
in https://developer.android.com/reference/android/support/v7/widget/RecyclerView.html#setOnScrollListener%28android.support.v7.widget.RecyclerView.OnScrollListener%29. Use that
EDIT:
Override onScrollStateChanged
method inside the onScrollListener
and do this
boolean loadMore = firstVisibleItem + visibleItemCount >= totalItemCount;
//loading is used to see if its already loading, you have to manually manipulate this boolean variable
if (loadMore && !loading) {

I had the same error and the problem is that I had not correctly installed Composer.

You can use the Attribute.IsDefined method
https://msdn.microsoft.com/en-us/library/system.attribute.isdefined(v=vs.110).aspx
if(Attribute.IsDefined(YourProperty,typeof(YourAttribute)))
{
//Conditional execution...
}
You could provide the property you're specifically looking for or you could iterate through all of them using reflection, something like:
PropertyInfo[] props = typeof(YourClass).GetProperties();
Another, unfortunately highly OS-dependent, solution is memory mapping the file. The benefits generally include performance of the read, and reduced memory use as the applications view and operating systems file cache can actually share the physical memory.
POSIX code would look like this:
int fd = open("filename", O_RDONLY);
int len = lseek(fd, 0, SEEK_END);
void *data = mmap(0, len, PROT_READ, MAP_PRIVATE, fd, 0);
Windows on the other hand is little more tricky, and unfortunately I don't have a compiler in front of me to test, but the functionality is provided by CreateFileMapping()
and MapViewOfFile()
.
The question is how to call a C function from Python, if I understood correctly. Then the best bet are Ctypes (BTW portable across all variants of Python).
>>> from ctypes import *
>>> libc = cdll.msvcrt
>>> print libc.time(None)
1438069008
>>> printf = libc.printf
>>> printf("Hello, %s\n", "World!")
Hello, World!
14
>>> printf("%d bottles of beer\n", 42)
42 bottles of beer

There isn't, where would it go?
Use CSS to put a border-right on an element if you want something like that.
During the focus event you can scroll past the document height and magically the window.innerHeight is reduced by the height of the virtual keyboard. Note that the size of the virtual keyboard is different for landscape vs. portrait orientations so you'll need to redetect it when it changes. I would advise against remembering these values as the user could connect/disconnect a bluetooth keyboard at any time.
var element = document.getElementById("element"); // the input field
var focused = false;
var virtualKeyboardHeight = function () {
var sx = document.body.scrollLeft, sy = document.body.scrollTop;
var naturalHeight = window.innerHeight;
window.scrollTo(sx, document.body.scrollHeight);
var keyboardHeight = naturalHeight - window.innerHeight;
window.scrollTo(sx, sy);
return keyboardHeight;
};
element.onfocus = function () {
focused = true;
setTimeout(function() {
element.value = "keyboardHeight = " + virtualKeyboardHeight()
}, 1); // to allow for orientation scrolling
};
window.onresize = function () {
if (focused) {
element.value = "keyboardHeight = " + virtualKeyboardHeight();
}
};
element.onblur = function () {
focused = false;
};
Note that when the user is using a bluetooth keyboard, the keyboardHeight is 44 which is the height of the [previous][next] toolbar.
There is a tiny bit of flicker when you do this detection, but it doesn't seem possible to avoid it.
I'm adding this answer because after researching the web, I ended up at this answer but still didn't know which subfolder of the IIS logs folder to look in.
If your server has multiple websites, you will need to know the IIS ID for the site. An easy way to get this in IIS is to simply click on the Sites folder in the left panel. The ID for each site is shown in the right panel.
Once you know the ID, let's call it n, the corresponding logs are in the W3SVCn subfolder of the IIS logs folder. So, if your website ID is 4, say, and the IIS logs are in the default location, then the logs are in this folder:
%SystemDrive%\inetpub\logs\LogFiles\W3SVC4

You can use ORDER BY ID DESC
, but it's WAY faster if you go that way:
SELECT * FROM bugs WHERE ID = (SELECT MAX(ID) FROM bugs WHERE user = 'me')
In case that you have a huge table, it could make a significant difference.
EDIT
You can even set a variable in case you need it more than once (or if you think it is easier to read).
SELECT @bug_id := MAX(ID) FROM bugs WHERE user = 'me';
SELECT * FROM bugs WHERE ID = @bug_id;
best way for Python 3 is:
pip3 freeze > requirements.txt
it worked for me...
I would use EHP
Here it is:
from ehp import *
doc = '''<html>
<head>Heading</head>
<body attr1='val1'>
<div class='container'>
<div id='class'>Something here</div>
<div>Something else</div>
</div>
</body>
</html>
'''
html = Html()
dom = html.feed(doc)
for ind in dom.find('div', ('class', 'container')):
print ind.text()
Output:
Something here
Something else
Honestly, I'd recommend using phpseclib, a pure PHP SSH2 implementation. Example:
<?php
include('Net/SSH2.php');
$ssh = new Net_SSH2('www.domain.tld');
if (!$ssh->login('username', 'password')) {
exit('Login Failed');
}
echo $ssh->exec('pwd');
echo $ssh->exec('ls -la');
?>
It's a ton more portable, easier to use and more feature packed too.
VB 6 provides a Clipboard
object that makes all of this extremely simple and convenient, but unfortunately that's not available from VBA.
If it were me, I'd go the API route. There's no reason to be scared of calling native APIs; the language provides you with the ability to do that for a reason.
However, a simpler alternative is to use the DataObject
class, which is part of the Forms library. I would only recommend going this route if you are already using functionality from the Forms library in your app. Adding a reference to this library only to use the clipboard seems a bit silly.
For example, to place some text on the clipboard, you could use the following code:
Dim clipboard As MSForms.DataObject
Set clipboard = New MSForms.DataObject
clipboard.SetText "A string value"
clipboard.PutInClipboard
Or, to copy text from the clipboard into a string variable:
Dim clipboard As MSForms.DataObject
Dim strContents As String
Set clipboard = New MSForms.DataObject
clipboard.GetFromClipboard
strContents = clipboard.GetText
according to mysql documentation none of these works! People pay attention! so we will upload test.sql into the test_db type this into the shell:
mysql --user=user_name --password=yourpassword test_db < d:/test.sql
Ok after having sunk way to much time into this problem this is the way I managed to get the appearance I was hoping for. I'm making it a separate answer so I can get everything in one place.
It's a combination of factors.
Firstly, don't try to get the toolbars to play nice through just themes. It seems to be impossible.
So apply themes explicitly to your Toolbars like in oRRs answer
layout/toolbar.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_alignParentTop="true"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:theme="@style/Dark.Overlay"
app:popupTheme="@style/Dark.Overlay.LightPopup" />
However this is the magic sauce. In order to actually get the background colors I was hoping for you have to override the background
attribute in your Toolbar themes
values/styles.xml:
<!--
I expected android:colorBackground to be what I was looking for but
it seems you have to override android:background
-->
<style name="Dark.Overlay" parent="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
<item name="android:background">?attr/colorPrimary</item>
</style>
<style name="Dark.Overlay.LightPopup" parent="ThemeOverlay.AppCompat.Light">
<item name="android:background">@color/material_grey_200</item>
</style>
then just include your toolbar layout in your other layouts
<include android:id="@+id/mytoolbar" layout="@layout/toolbar" />
and you're good to go.
Hope this helps someone else so you don't have to spend as much time on this as I have.
(if anyone can figure out how to make this work using just themes, ie not having to apply the themes explicitly in the layout files I'll gladly support their answer instead)
EDIT:
So apparently posting a more complete answer was a downvote magnet so I'll just accept the imcomplete answer above but leave this answer here in case someone actually needs it. Feel free to keep downvoting if it makes you happy though.
You can access capturing groups like this:
var myString = "something format_abc";_x000D_
var myRegexp = /(?:^|\s)format_(.*?)(?:\s|$)/g;_x000D_
var match = myRegexp.exec(myString);_x000D_
console.log(match[1]); // abc
_x000D_
And if there are multiple matches you can iterate over them:
var myString = "something format_abc";_x000D_
var myRegexp = /(?:^|\s)format_(.*?)(?:\s|$)/g;_x000D_
match = myRegexp.exec(myString);_x000D_
while (match != null) {_x000D_
// matched text: match[0]_x000D_
// match start: match.index_x000D_
// capturing group n: match[n]_x000D_
console.log(match[0])_x000D_
match = myRegexp.exec(myString);_x000D_
}
_x000D_
As you can see the way to iterate over multiple matches was not very intuitive. This lead to the proposal of the String.prototype.matchAll
method. This new method is expected to ship in the ECMAScript 2020 specification. It gives us a clean API and solves multiple problems. It has been started to land on major browsers and JS engines as Chrome 73+ / Node 12+ and Firefox 67+.
The method returns an iterator and is used as follows:
const string = "something format_abc";_x000D_
const regexp = /(?:^|\s)format_(.*?)(?:\s|$)/g;_x000D_
const matches = string.matchAll(regexp);_x000D_
_x000D_
for (const match of matches) {_x000D_
console.log(match);_x000D_
console.log(match.index)_x000D_
}
_x000D_
As it returns an iterator, we can say it's lazy, this is useful when handling particularly large numbers of capturing groups, or very large strings. But if you need, the result can be easily transformed into an Array by using the spread syntax or the Array.from
method:
function getFirstGroup(regexp, str) {
const array = [...str.matchAll(regexp)];
return array.map(m => m[1]);
}
// or:
function getFirstGroup(regexp, str) {
return Array.from(str.matchAll(regexp), m => m[1]);
}
In the meantime, while this proposal gets more wide support, you can use the official shim package.
Also, the internal workings of the method are simple. An equivalent implementation using a generator function would be as follows:
function* matchAll(str, regexp) {
const flags = regexp.global ? regexp.flags : regexp.flags + "g";
const re = new RegExp(regexp, flags);
let match;
while (match = re.exec(str)) {
yield match;
}
}
A copy of the original regexp is created; this is to avoid side-effects due to the mutation of the lastIndex
property when going through the multple matches.
Also, we need to ensure the regexp has the global flag to avoid an infinite loop.
I'm also happy to see that even this StackOverflow question was referenced in the discussions of the proposal.
Two steps worked for me:
gem install bundler
bundle install --redownload # Forces a redownload of all gems on the gemfile, assigning them to the new bundler

Creating a custom filter might be overkill here, you can just pass in a custom comparator, if you have the multiples values like:
$scope.selectedGenres = "Action, Drama";
$scope.containsComparator = function(expected, actual){
return actual.indexOf(expected) > -1;
};
then in the filter:
filter:{name:selectedGenres}:containsComparator
I was also facing the error "Error preloading the connection pool" while using Oracle 10g Express Edition with my Spring and CAS based application during login.

HttpURLConnection
has a setConnectTimeout method.
Just set the timeout to 5000 milliseconds, and then catch java.net.SocketTimeoutException
Your code should look something like this:
try {
HttpURLConnection.setFollowRedirects(false);
HttpURLConnection con = (HttpURLConnection) new URL(url).openConnection();
con.setRequestMethod("HEAD");
con.setConnectTimeout(5000); //set timeout to 5 seconds
return (con.getResponseCode() == HttpURLConnection.HTTP_OK);
} catch (java.net.SocketTimeoutException e) {
return false;
} catch (java.io.IOException e) {
return false;
}
Streams are often accessed by threads that periodically empty their content and, for example, display it on the screen, send it to a socket or write it to a file. This is done for performance reasons. Flushing an output stream means that you want to stop, wait for the content of the stream to be completely transferred to its destination, and then resume execution with the stream empty and the content sent.
I'll just add that Xcode 4.5 includes the new dequeueReusableCellWithIdentifier:forIndexPath:
in its default template code - a potential gotcha for developers expecting the older dequeueReusableCellWithIdentifier:
method.
Whenever one has a dictionary where the values are integers, the Counter data structure is often a better choice to represent the data than a dictionary.
If you already have a dictionary, a counter can easily be formed by:
c = Counter(d['123'])
as an example from your data.
The most_common
function allows easy access to descending order of the items in the counter
The more complete writeup on the Counter data structure is at https://docs.python.org/2/library/collections.html
If you just want to remove the first two characters and the last two, then you can use negative indexes on the string:
s = "((String1))"
s = s[2...-2]
p s # => "String1"
If you want to remove all parentheses from the string you can use the delete method on the string class:
s = "((String1))"
s.delete! '()'
p s # => "String1"
package com;
import java.io.File;
public class Delete {
public static void main(String[] args) {
String files;
File file = new File("D:\\del\\yc\\gh");
File[] listOfFiles = file.listFiles();
for (int i = 0; i < listOfFiles.length; i++)
{
if (listOfFiles[i].isFile())
{
files = listOfFiles[i].getName();
System.out.println(files);
if(!files.equalsIgnoreCase("Scan.pdf"))
{
boolean issuccess=new File(listOfFiles[i].toString()).delete();
System.err.println("Deletion Success "+issuccess);
}
}
}
}
}
If you want to delete all files remove
if(!files.equalsIgnoreCase("Scan.pdf"))
statement it will work.
You can also try out cliqr
. Its pretty new and in active development. But there are stable releases ready to be used. Here is the git repo: https://github.com/anshulverma/cliqr
Look into the example folder to get an idea on how it can be used.
Depending on how you are running the command, you can put /k
after cmd
to keep the window open.
cmd /k my_script.bat
Simply adding cmd /k
to the end of your batch file will work too. Credit to Luigi D'Amico who posted about this in the comments below.
The equivalent JPA mapping for the DDL ON DELETE CASCADE
is cascade=CascadeType.REMOVE
. Orphan removal means that dependent entities are removed when the relationship to their "parent" entity is destroyed. For example if a child is removed from a @OneToMany
relationship without explicitely removing it in the entity manager.
If openssl installation was successfull, search for "OPENSSL" in c drive to locate the config file and set the path.
set OPENSSL_CONF=<location where cnf is available>/openssl.cnf
It worked out for me.
First of all you can use the short notation @click
instead of v-on:click
for readability purposes.
Second You can use a click event handler that calls other functions/methods as @Tushar mentioned in his comment above, so you end up with something like this :
<div id="app">
<div @click="handler('foo','bar')">
Hi, click me!
</div>
</div>

There are several reasons to want to know what the device is.
You can check the device height (and width). This is useful for layout, but you usually don't want to do that if you want to know the exact device.
For layout purposes, you can also use UIView.safeAreaInsets
.
If you want to display the device name, for example, to be included in a email for diagnostic purposes, after retrieving the device model using sysctl ()
, you can use the equivalent of this to figure the name:
$ curl http://appledevicenames.com/devices/iPhone10,6
iPhone X
In Chrome, go to options (Customize and Control, the 3 dots/bars at top right) ---> More Tools ---> save page as
save page as
filename : any_name.html
save as type : webpage complete.
Then you will get any_name.html
and any_name folder
.
Because comparaison method have to be done based on type int (x==y) or class Integer (x.equals(y)) with right operator
public class Example {
public static void main(String[] args) {
int[] arr = {-32735, -32735, -32700, -32645, -32645, -32560, -32560};
for(int j=1; j<arr.length-1; j++)
if((arr[j-1]!=arr[j]) && (arr[j]!=arr[j+1]))
System.out.println("int>"+arr[j]);
Integer[] I_arr = {-32735, -32735, -32700, -32645, -32645, -32560, -32560};
for(int j=1; j<I_arr.length-1; j++)
if((!I_arr[j-1].equals(I_arr[j])) && (!I_arr[j].equals(I_arr[j+1])))
System.out.println("Interger>"+I_arr[j]);
}
}
Use parseJSON
. Look at the doc
var obj = $.parseJSON(data);
Something like this:
$.ajax({
type: "POST",
url: '/admin/systemgoalssystemgoalupdate?format=html',
data: formdata,
success: function (data) {
console.log($.parseJSON(data)); //will log Object
}
});
I came here hoping to find a way to get the sum across all columns in a data table and run into issues implementing the above solutions. A way to add a column with the sum across all columns uses the cbind
function:
cbind(data, total = rowSums(data))
This method adds a total
column to the data and avoids the alignment issue yielded when trying to sum across ALL columns using the above solutions (see the post below for a discussion of this issue).
<html>
<head>
<script>
function frameSize(id){
var frameHeight;

}
document.getElementById(id).height= (frameHeight) + "px";

See the documentation for the print function: print()
The content of end
is printed after the thing you want to print. By default it contains a newline ("\n"
) but it can be changed to something else, like an empty string.
Sometimes, the database will not be mounted correctly, so we need to mount it manually. For that, shut it down and start it up then mount. Log in as oracle user, then run the following commands:
sqlplus / as sysdba;
shutdown immediate;
startup nomount;
alter database mount;
alter database open;
To break a loop, use break
instead of return
.
Or put the loop or control construct into a function, only functions can return values.
Both files define variable k
as an integer (int
).
As a result, the linker sees two variables with the same name, and is unsure which one it should use if you ever refer to k
.
To fix this, change one of the declarations to:
extern int k;
That means: "k is an integer, declared here, but defined externally (ie. the other file)."
Now there is only one variable k
, that can be properly referred to by two different files.
For current datetime, you can use now() function in postgresql insert query.
You can also refer following link.

$type=12 //it's integer
mysql_query("INSERT INTO contents (type, reporter, description) VALUES($type, 'john', 'whatever')");//at that time u can use $type

If your InputStream is backed by a Socket, you can set a Socket timeout (in milliseconds) using setSoTimeout. If the read() call doesn't unblock within the timeout specified, it will throw a SocketTimeoutException.
Just make sure that you call setSoTimeout on the Socket before making the read() call.
If you are having similar issues with pure components or classes, ensure you are using .js
extension instead of .jsx
.
Primary Key and Unique Key are Entity integrity constraints
Primary key allows each row in a table to be uniquely identified and ensures that no duplicate rows exist and no null values are entered.
Unique key constraint is used to prevent the duplication of key values within the rows of a table and allow null values. (In oracle one null is not equal to another null).
see Differences between INDEX, PRIMARY, UNIQUE, FULLTEXT in MySQL?
to pass many options you can pass a object to a @Input decorator with custom data in a single line.
In the template
<li *ngFor = 'let opt of currentQuestion.options'
[selectable] = 'opt'
[myOptions] ="{first: opt.val1, second: opt.val2}" // these are your multiple parameters
(selectedOption) = 'onOptionSelection($event)' >
{{opt.option}}
</li>
so in Directive class
@Directive({
selector: '[selectable]'
})
export class SelectableDirective{
private el: HTMLElement;
@Input('selectable') option:any;
@Input('myOptions') data;
//do something with data.first
...
// do something with data.second
}

There are few answers here indicating both strategies for 2 different versions of Jackson library below:
For Jackson 2.6.*
ObjectMapper objMapper = new ObjectMapper(new JsonFactory()); // or YAMLFactory()
objMapper.setNamingStrategy(
PropertyNamingStrategy.CAMEL_CASE_TO_LOWER_CASE_WITH_UNDERSCORES);
For Jackson 2.7.*
ObjectMapper objMapper = new ObjectMapper(new JsonFactory()); // or YAMLFactory()
objMapper.setNamingStrategy(
PropertyNamingStrategy.SNAKE_CASE);
Simplest way to throw an Exception in C++:
#include <iostream>
using namespace std;
void purturb(){
throw "Cannot purturb at this time.";
}
int main() {
try{
purturb();
}
catch(const char* msg){
cout << "We caught a message: " << msg << endl;
}
cout << "done";
return 0;
}
This prints:
We caught a message: Cannot purturb at this time.
done
If you catch the thrown exception, the exception is contained and the program will ontinue. If you do not catch the exception, then the program exists and prints:
This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information.

To disable a submit button, you just need to add a disabled attribute to the submit button.
$("#btnSubmit").attr("disabled", true);
To enable a disabled button, set the disabled attribute to false, or remove the disabled attribute.
$('#btnSubmit').attr("disabled", false);
or
$('#btnSubmit').removeAttr("disabled");
Have a look at the Requests exception docs. In short:
In the event of a network problem (e.g. DNS failure, refused connection, etc), Requests will raise a
ConnectionError
exception.In the event of the rare invalid HTTP response, Requests will raise an
HTTPError
exception.If a request times out, a
Timeout
exception is raised.If a request exceeds the configured number of maximum redirections, a
TooManyRedirects
exception is raised.All exceptions that Requests explicitly raises inherit from
requests.exceptions.RequestException
.
To answer your question, what you show will not cover all of your bases. You'll only catch connection-related errors, not ones that time out.
What to do when you catch the exception is really up to the design of your script/program. Is it acceptable to exit? Can you go on and try again? If the error is catastrophic and you can't go on, then yes, you may abort your program by raising SystemExit (a nice way to both print an error and call sys.exit
).
You can either catch the base-class exception, which will handle all cases:
try:
r = requests.get(url, params={'s': thing})
except requests.exceptions.RequestException as e: # This is the correct syntax
raise SystemExit(e)
Or you can catch them separately and do different things.
try:
r = requests.get(url, params={'s': thing})
except requests.exceptions.Timeout:
# Maybe set up for a retry, or continue in a retry loop
except requests.exceptions.TooManyRedirects:
# Tell the user their URL was bad and try a different one
except requests.exceptions.RequestException as e:
# catastrophic error. bail.
raise SystemExit(e)
As Christian pointed out:
If you want http errors (e.g. 401 Unauthorized) to raise exceptions, you can call
Response.raise_for_status
. That will raise anHTTPError
, if the response was an http error.
An example:
try:
r = requests.get('http://www.google.com/nothere')
r.raise_for_status()
except requests.exceptions.HTTPError as err:
raise SystemExit(err)
Will print:
404 Client Error: Not Found for url: http://www.google.com/nothere

You could use a Common Table Expression to create the SUM first, join it to the table, and then use the WHEN to to get the value from the CTE or the original table as necessary.
WITH PercentageOfTotal (Id, Percentage)
AS
(
SELECT Id, (cnt / SUM(AreaId)) FROM dbo.MyTable GROUP BY Id
)
SELECT
CASE
WHEN o.TotalType = 'Average' THEN r.avgscore
WHEN o.TotalType = 'PercentOfTot' THEN pt.Percentage
ELSE o.cnt
END AS [displayscore]
FROM PercentageOfTotal pt
JOIN dbo.MyTable t ON pt.Id = t.Id

Dupx
Dupx is a simple *nix utility to redirect standard output/input/error of an already running process.
Motivation
I've often found myself in a situation where a process I started on a remote system via SSH takes much longer than I had anticipated. I need to break the SSH connection, but if I do so, the process will die if it tries to write something on stdout/error of a broken pipe. I wish I could suspend the process with ^Z and then do a
bg %1 >/tmp/stdout 2>/tmp/stderr
Unfortunately this will not work (in shells I know).
In windows server 2012, even after installing asp.net you might run into this issue.
Check for "Http activation" feature. This feature is present under Web services as well.
Make sure you add the above and everything should be awesome for you !!!
Those who prefer to use laravel helpers they can check if a request is ajax using laravel request()
helper.

For z-index to work, you also need to give it a position:
header {
width: 100%;
height: 100px;
background: url(../img/top.png) repeat-x;
z-index: 110;
position: relative;
}

Less common cases, but keep in mind that according to DOC https://dev.mysql.com/doc/refman/5.6/en/innodb-online-ddl-limitations.html
When running an online ALTER TABLE operation, the thread that runs the ALTER TABLE operation will apply an “online log” of DML operations that were run concurrently on the same table from other connection threads. When the DML operations are applied, it is possible to encounter a duplicate key entry error (ERROR 1062 (23000): Duplicate entry), even if the duplicate entry is only temporary and would be reverted by a later entry in the “online log”. This is similar to the idea of a foreign key constraint check in InnoDB in which constraints must hold during a transaction.
Here's an example of a person who wants to convert a blob to char(1000) with UTF-8 encoding:
CAST(a.ar_options AS CHAR(10000) CHARACTER SET utf8)
This is his answer. There is probably much more you can read about CAST right here. I hope it helps some.
Yes, using ++X, X+1 will be used in the expression. Using X++, X will be used in the expression and X will only be increased after the expression has been evaluated.
So if X = 9, using ++X, the value 10 will be used, else, the value 9.
This is one of the method to overcome this issue.

Element
objects have no .getroot()
method. Drop that call, and the .tostring()
call works:
xmlstr = ElementTree.tostring(et, encoding='utf8', method='xml')
You only need to use .getroot()
if you have an ElementTree
instance.
Other notes:
This produces a bytestring, which in Python 3 is the bytes
type.
If you must have a str
object, you have two options:
Decode the resulting bytes value, from UTF-8: xmlstr.decode("utf8")
Use encoding='unicode'
; this avoids an encode / decode cycle:
xmlstr = ElementTree.tostring(et, encoding='unicode', method='xml')
If you wanted the UTF-8 encoded bytestring value or are using Python 2, take into account that ElementTree doesn't properly detect utf8
as the standard XML encoding, so it'll add a <?xml version='1.0' encoding='utf8'?>
declaration. Use utf-8
or UTF-8
(with a dash) if you want to prevent this. When using encoding="unicode"
no declaration header is added.
Matching any text but those matching a pattern is usually achieved with splitting the string with the regex pattern.
Examples:
Regex.Split(text, @"red|green|blue")
or, to get rid of empty values, Regex.Split(text, @"red|green|blue").Where(x => !string.IsNullOrEmpty(x))
(see demo)Regex.Split(text, "red|green|blue")
or, to remove empty items, Regex.Split(text, "red|green|blue").Where(Function(s) Not String.IsNullOrWhitespace(s))
(see demo, or this demo where LINQ is supported)text.split(/red|green|blue/)
(no need to use g
modifier here!) (to get rid of empty values, use text.split(/red|green|blue/).filter(Boolean)
), see demotext.split("red|green|blue")
, or - to keep all trailing empty items - use text.split("red|green|blue", -1)
, or to remove all empty items use more code to remove them (see demo)text.split(/red|green|blue/)
, to get all trailing items use text.split(/red|green|blue/, -1)
and to remove all empty items use text.split(/red|green|blue/).findAll {it != ""})
(see demo)text.split(Regex("red|green|blue"))
or, to remove blank items, use text.split(Regex("red|green|blue")).filter{ !it.isBlank() }
, see demotext.split("red|green|blue")
, or to keep all trailing empty items, use text.split("red|green|blue", -1)
and to remove all empty items, use text.split("red|green|blue").filter(_.nonEmpty)
(see demo)text.split(/red|green|blue/)
, to get rid of empty values use .split(/red|green|blue/).reject(&:empty?)
(and to get both leading and trailing empty items, use -1
as the second argument, .split(/red|green|blue/, -1)
) (see demo)my @result1 = split /red|green|blue/, $text;
, or with all trailing empty items, my @result2 = split /red|green|blue/, $text, -1;
, or without any empty items, my @result3 = grep { /\S/ } split /red|green|blue/, $text;
(see demo)preg_split('~red|green|blue~', $text)
or preg_split('~red|green|blue~', $text, -1, PREG_SPLIT_NO_EMPTY)
to output no empty items (see demo)re.split(r'red|green|blue', text)
or, to remove empty items, list(filter(None, re.split(r'red|green|blue', text)))
(see demo)regexp.MustCompile("red|green|blue").Split(text, -1)
, and if you need to remove empty items, use this code. See Go demo.NOTE: If you patterns contain capturing groups, regex split functions/methods may behave differently, also depending on additional options. Please refer to the appropriate split method documentation then.
Since this is caused by a misconfiguration of the network you are operating on just setup your smartphone to share its internet connection using USB tethering and use it to download the missing packages.

In Google's closure library project , there is a module which has do the job , below is the API and source code.
Basically you need following things to make location detector android app
Now if you write each of these module yourself then it needs much time and efforts. So it would be better to use ready resources that are being maintained already.
Using all these resources, you will be able to create an flawless android location detection app.
You will first need to listen for current location of user. You can use any of below libraries to quick start.
This library provide last known location, location updates
With this library you just need to provide a Configuration object with your requirements, and you will receive a location or a fail reason with all the stuff are described above handled.
Use this open source repo of the Hypertrack Live app to build live location sharing experience within your app within a few hours. HyperTrack Live app helps you share your Live Location with friends and family through your favorite messaging app when you are on the way to meet up. HyperTrack Live uses HyperTrack APIs and SDKs.
Google Maps Android API utility library
If you want to add route maps feature in your apps you can use DrawRouteMaps to make you work more easier. This is lib will help you to draw route maps between two point LatLng.
Simple, smooth animation for route / polylines on google maps using projections. (WIP)
This project allows you to calculate the direction between two locations and display the route on a Google Map using the Google Directions API.
Try modifying the "style" attribute:
$('myObject').attr('style', 'background-image: url("' + imageUrl +'")');
I was also having the problem while running the carthage script in the build phase. (Xcode 9) I get that dialog for each and every framework I had added plus the app itself. You can see a very dark shadow growing. I could bypass it by entering the password every time and hitting "Always Allow".
For IntelliJ IDEA 2017.2 I did the following to fix this issue: Go to your project structure Now go to SDKs under platform settings and click the green add button. Add your JDK path. In my case it was this path C:\Program Files\Java\jdk1.8.0_144 Now Just go Project under Project settings and select the project SDK.
Converting Current DateTime in UTC:
DateTimeFormatter formatter = DateTimeFormat.forPattern("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
DateTimeZone dateTimeZone = DateTimeZone.getDefault(); //Default Time Zone
DateTime currDateTime = new DateTime(); //Current DateTime
long utcTime = dateTimeZone.convertLocalToUTC(currDateTime .getMillis(), false);
String currTime = formatter.print(utcTime); //UTC time converted to string from long in format of formatter
currDateTime = formatter.parseDateTime(currTime); //Converted to DateTime in UTC
It only safer as long as you don't build with -Wno-narrowing like say Google does in Chromium. If you do, then it is LESS safe. Without that flag the only unsafe cases will be fixed by C++20 though.
Note: A) Curly brackets are safer because they don't allow narrowing. B) Curly brackers are less safe because they can bypass private or deleted constructors, and call explicit marked constructors implicitly.
Those two combined means they are safer if what is inside is primitive constants, but less safe if they are objects (though fixed in C++20)
Might be useful. I needed the action in the constructor of the controller, and it appears at this point of the MVC lifecycle, this
hasn't initialized, and ControllerContext = null
. Instead of delving into the MVC lifecycle and finding the appropriate function name to override, I just found the action in the RequestContext.RouteData
.
But in order to do so, as with any HttpContext
related uses in the constructor, you have to specify the full namespace, because this.HttpContext
also hasn't been initialized. Luckily, it appears System.Web.HttpContext.Current
is static.
// controller constructor
public MyController() {
// grab action from RequestContext
string action = System.Web.HttpContext.Current.Request.RequestContext.RouteData.GetRequiredString("action");
// grab session (another example of using System.Web.HttpContext static reference)
string sessionTest = System.Web.HttpContext.Current.Session["test"] as string
}
NOTE: likely not the most supported way to access all properties in HttpContext, but for RequestContext and Session it appears to work fine in my application.
If I could suggest setting up your dataframes like this (auto-indexing):
df = pd.DataFrame({'a':[np.nan, 1, 2], 'b':[4, 5, 6]})
then you can set up your s1 and s2 values thus (using shape() to return the number of rows from df):
s = pd.DataFrame({'s1':[5]*df.shape[0], 's2':[6]*df.shape[0]})
then the result you want is easy:
display (df.merge(s, left_index=True, right_index=True))
Alternatively, just add the new values to your dataframe df:
df = pd.DataFrame({'a':[nan, 1, 2], 'b':[4, 5, 6]})
df['s1']=5
df['s2']=6
display(df)
Both return:
a b s1 s2
0 NaN 4 5 6
1 1.0 5 5 6
2 2.0 6 5 6
If you have another list of data (instead of just a single value to apply), and you know it is in the same sequence as df, eg:
s1=['a','b','c']
then you can attach this in the same way:
df['s1']=s1
returns:
a b s1
0 NaN 4 a
1 1.0 5 b
2 2.0 6 c
I'm probably going a million miles in the wrong direct (but i'm only young :P ). but couldn't you add the graphic to a panel and then a mouselistener to the graphic object so that when the user on the graphic your action is preformed.
Following is the way to change the color of the left icon in edit text and set it in left side.
Drawable img = getResources().getDrawable( R.drawable.user );
img.setBounds( 0, 0, 60, 60 );
mNameEditText.setCompoundDrawables(img,null, null, null);
int color = ContextCompat.getColor(this, R.color.blackColor);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
DrawableCompat.setTint(img, color);
} else {
img.mutate().setColorFilter(color, PorterDuff.Mode.SRC_IN);
}
Anyway the "Block" method is preffered now-a-days. I will explain the simple block below.
Consider the snipped below. bug2 and bug 3 are imageViews. The below animation describes an animation with 1 second duration after a delay of 1 second. The bug3 is moved from its center to bug2's center. Once the animation is completed it will be logged "Center Animation Done!".
-(void)centerAnimation:(id)sender
{
NSLog(@"Center animation triggered!");
CGPoint bug2Center = bug2.center;
[UIView animateWithDuration:1
delay:1.0
options: UIViewAnimationCurveEaseOut
animations:^{
bug3.center = bug2Center;
}
completion:^(BOOL finished){
NSLog(@"Center Animation Done!");
}];
}
Hope that's clean!!!
Since you're using Tortoise you may want to check out this link on LosTechies. It should be almost exactly what you are looking for.
This resource(broken link) is also worth considering - some very tidy code that uses GD. However, I modified their final code snippet to create this function which meets the OPs requirements...
function store_uploaded_image($html_element_name, $new_img_width, $new_img_height) {
$target_dir = "your-uploaded-images-folder/";
$target_file = $target_dir . basename($_FILES[$html_element_name]["name"]);
$image = new SimpleImage();
$image->load($_FILES[$html_element_name]['tmp_name']);
$image->resize($new_img_width, $new_img_height);
$image->save($target_file);
return $target_file; //return name of saved file in case you want to store it in you database or show confirmation message to user
}
You will also need to include this PHP file...

You could ask your colleague to create a patch, which will collapse all the changes that have been made into a single file that you can apply to your own check out. This will update all of your files appropriately and then you can revert the changes on his side and check yours in.
Consider both at the same time:
Furthermore, I suggest that you expand your Context to include not only access to singleton objects but some functionalities that need to be accessed globally, like for example: context.logOffUser(), context.readSavedData(), etc. Probably renaming the Context to Facade would make sense then.

Though weirdly named, you can use the getimagesize()
function. This will also give you mime information:
Array
(
[0] => 295 // width
[1] => 295 // height
[2] => 3 // http://php.net/manual/en/image.constants.php
[3] => width="295" height="295" // width and height as attr's
[bits] => 8
[mime] => image/png
)
There is always this of course:
(async () => {
await ...
// all of the script....
})();
// nothing else
This makes a quick function with async where you can use await. It saves you the need to make an async function which is great! //credits Silve2611
I Found that removing the references to Entity Framework and installing the latest version of Entity Framework from NuGet fixed the issue. It recreates all the required entries for you during install.

It's nano seconds, what are the chances of getting the same seed twice.
Anyway, thanks for the help, here is my end solution based on all the input.
package main
import (
"math/rand"
"time"
)
func init() {
rand.Seed(time.Now().UTC().UnixNano())
}
// generates a random string
func srand(min, max int, readable bool) string {
var length int
var char string
if min < max {
length = min + rand.Intn(max-min)
} else {
length = min
}
if readable == false {
char = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789"
} else {
char = "ABCDEFHJLMNQRTUVWXYZabcefghijkmnopqrtuvwxyz23479"
}
buf := make([]byte, length)
for i := 0; i < length; i++ {
buf[i] = char[rand.Intn(len(char)-1)]
}
return string(buf)
}
// For testing only
func main() {
println(srand(5, 5, true))
println(srand(5, 5, true))
println(srand(5, 5, true))
println(srand(5, 5, false))

Without over-complicating the problem, to grant the EXECUTE on chosen database:
USE [DB]
GRANT EXEC TO [User_Name];
It is good practice to make sure the callback is an actual function before attempting to execute it:
if (callback && typeof(callback) === "function") {
callback();
}
Interesting that I didn't see a mention of UTM coordinates.
https://en.wikipedia.org/wiki/Universal_Transverse_Mercator_coordinate_system.
At least if you want to add km to the same zone, it should be straightforward (in Python : https://pypi.org/project/utm/ )
utm.from_latlon and utm.to_latlon.
All your controls are belong to us!
Fionnuala answered this correctly but skimmers like me would find it easy to miss the point.
You don't refresh the subFORM you refresh the subform CONTROL. In fact, if you check with allforms() the subForm isn't even loaded as far as access is concerned.
On the main form look at the label the subform wizard provided or select the subform by clicking once or on the border around it and look at the "caption" in the "Other" tab in properties. That's the name you use for requerying, not the name of the form that appears in the navigation panel.
In my case I had a subform called frmInvProdSub and I tried for many hours to figure out why Access didn't think it existed. I gave up, deleted the form and re-created it. The very last step is telling it what you want to call the control so I called it frmInvProdSub and finished the wizard. Then I tried and voila, it worked!
When I looked at the form name in the navigation window I realized I'd forgotten to put "Sub" in the name! That's when it clicked. The CONTROL is called frmInvProdSub, not the form and using the control name works.
Of course if both names are identical then you didn't have this problem lol.
If all of these rows are related and you need to alter the tabular data ... why not just wrap the entire table in a form, and change GET
to POST
(unless you know that you're not going to be sending more than the max amount of data a GET
request can send).
(That's assuming, of course, that all of the data is going to the same place.)
<form method="POST" action="your_action">
<table>
<tr>
<td><input type="text" name="r1c1" value="" /></td>
<!-- ... snip ... -->
</tr>
<!-- ... repeat as needed ... -->
</table>
</form>
We face this error when permanent generation heap is full and some of us we use command prompt to build our maven project in windows. since we need to increase heap size, we could set our environment variable @ControlPanel/System and Security/System and there you click on Change setting and select Advanced and set Environment variable as below
find
supports -delete
operation, so:
find /base/dir/* -ctime +10 -delete;
I think there's a catch that the files need to be 10+ days older too. Haven't tried, someone may confirm in comments.
The most voted solution here is missing -maxdepth 0
so it will call rm -rf
for every subdirectory, after deleting it. That doesn't make sense, so I suggest:
find /base/dir/* -maxdepth 0 -type d -ctime +10 -exec rm -rf {} \;
The -delete
solution above doesn't use -maxdepth 0
because find
would complain the dir is not empty. Instead, it implies -depth
and deletes from the bottom up.
I found this question after seeing the 'more than one device' error, with 2 offline phones showing:
C:\Program Files (x86)\Android\android-sdk\android-tools>adb devices
List of devices attached
SH436WM01785 offline
SH436WM01785 offline
SH436WM01785 sideload
If you only have one device connected, run the following commands to get rid of the offline connections:
adb kill-server
adb devices
Something like this should suffice, to do what your batch file was doing (dumping the result set as semi-colon delimited text to the console):

if ( dt.Rows.Count == 0 )
{
// query returned no rows
}
else
{
//write semicolon-delimited header
string[] columnNames = dt.Columns
.Cast<DataColumn>()
.Select( c => c.ColumnName )
.ToArray()
;
string header = string.Join("," , columnNames) ;
Console.WriteLine(header) ;
// write each row
foreach ( DataRow dr in dt.Rows )
{
// get each rows columns as a string (casting null into the nil (empty) string
string[] values = new string[dt.Columns.Count];
for ( int i = 0 ; i < dt.Columns.Count ; ++i )
{
values[i] = ((string) dr[i]) ?? "" ; // we'll treat nulls as the nil string for the nonce

// construct the string to be dumped, quoting each value and doubling any embedded quotes.
string data = string.Join( ";" , values.Select( s => "\""+s.Replace("\"","\"\"")+"\"") ) ;

The following example turns an Iron Python Notebook called a_notebook.ipynb
into a python script called a_python_script.py
leaving out the cells tagged with the keyword remove
, which I add manually to the cells that I don't want to end up in the script, leaving out visualizations and other steps that once I am done with the notebook I don't need to be executed by the script.
import nbformat as nbf
from nbconvert.exporters import PythonExporter
from nbconvert.preprocessors import TagRemovePreprocessor
with open("a_notebook.ipynb", 'r', encoding='utf-8') as f:
the_notebook_nodes = nbf.read(f, as_version = 4)
trp = TagRemovePreprocessor()
trp.remove_cell_tags = ("remove",)
pexp = PythonExporter()
pexp.register_preprocessor(trp, enabled= True)
the_python_script, meta = pexp.from_notebook_node(the_notebook_nodes)
with open("a_python_script.py", 'w') as f:
f.writelines(the_python_script)

You can use the -Q --help=target
options:
gcc -march=native -Q --help=target ...
The -v
option may also be of use.
You can see the documentation on the --help
option here.
EDIT: Maybe your class for sending emails has an option for HTML emails and then you can use <br />
1) Double-quotes
$output = "Good news! The item# $item_number on which you placed a bid of \$ $bid_price is now available for purchase at your bid price.\nThe seller, $bid_user is making this offer.\n\nItem Title : $title\n\nAll the best,\n $bid_user\n$email\n";
If you use double-quotes then \n will work (there will be no newline in browser but see the source code in your browser - the \n characters will be replaced for newlines)
2) Single quotes doesn't have the effect as the double-quotes above:
$output = 'Good news! The item# $item_number on which you placed a bid of \$ $bid_price is now available for purchase at your bid price.\nThe seller, $bid_user is making this offer.\n\nItem Title : $title\n\nAll the best,\n $bid_user\n$email\n';
all characters will be printed as is (even variables!)
3) Line breaks in HTML
$html_output = "Good news! The item# $item_number on which you placed a bid of <br />$ $bid_price is now available for purchase at your bid price.<br />The seller, $bid_user is making this offer.<br /><br />Item Title : $title<br /><br />All the best,<br /> $bid_user<br />$email<br />";
Here's one method you can use. This is the answer for one of FreeCodeCamp Challenges:
function truncateString(str, num) {
if (str.length > num) {
return str.slice(0, num) + "...";
} else {
return str;
}
}
This can be done with MySQL, although it's highly unintuitive:
CREATE PROCEDURE p25 (OUT return_val INT)
BEGIN
DECLARE a,b INT;
DECLARE cur_1 CURSOR FOR SELECT s1 FROM t;
DECLARE CONTINUE HANDLER FOR NOT FOUND
SET b = 1;
OPEN cur_1;
REPEAT
FETCH cur_1 INTO a;
UNTIL b = 1
END REPEAT;
CLOSE cur_1;
SET return_val = a;
END;//

You can use $anchorScroll
.
Just inject $anchorScroll
as a dependency, and call $anchorScroll()
whenever you want to scroll to top.
You can't. The -c switch tells you when the permissions were last changed, -a tests the most recent access time, and -m tests the modification time. The filesystem used by most flavors of Linux (ext3) doesn't support a "creation time" record. Sorry!
You can just simply add the following code;
<a class="btn btn-primary" href="http://localhost:8080/Home" role="button">Home Page</a>
The best practice to download an image from Server or from Website and store it locally.
WebClient client=new Webclient();
client.DownloadFile("WebSite URL","C:\\....image.jpg");
client.Dispose();
In response to jt. You are correct, the HTML with just the password is susceptible to the Man in the middle attack. However, you can seed it with a GUID from the server ...
$.post(
'includes/login.php',
{ user: username, pass: $.md5(password + GUID) },
onLogin,
'json' );
This would defeat the Man-In-The middle ... in that the server would generate a new GUID for each attempt.
I had a similar requirement when running test locally instead of in docker. Basically I only wanted to install any .deb files found if they weren't already installed.
# If there are .deb files in the folder, then install them
if [ `ls -1 *.deb 2> /dev/null | wc -l` -gt 0 ]; then
for file in *.deb; do
# Only install if not already installed (non-zero exit code)
dpkg -I ${file} | grep Package: | sed -r 's/ Package:\s+(.*)/\1/g' | xargs dpkg -s
if [ $? != 0 ]; then
dpkg -i ${file}
fi;
done;
else
err "No .deb files found in '$PWD'"
fi
I guess they only problem I can see is that it doesn't check the version number of the package so if .deb file is a newer version, then this wouldn't overwrite the currently installed package.
Here's what I came up with:
std::stringstream trimmer;
trimmer << str;
trimmer >> str;
Stream extraction eliminates whitespace automatically, so this works like a charm.
Pretty clean and elegant too, if I do say so myself. ;)
TLDR: You need to stop the server Ctrl + c and start again using php artisan serve
If you are using Laravel, and have started local dev server already by php artisan serve
And after having above server already running, you change your database server related stuff in .env file. Like moving from MySQL to SQLite or something. You need to make sure that you stop above process i.e. Ctrcl C
or anything which stop the process. And then restart Artisan Serve again i.e. y php artisan serve
and refresh your browser and your issue related to database will be fixed. This is what worked for me for Laravel 5.3
Try adding LayoutParams
and MaxWidth
and MaxHeight
to the TextView
. It will force the layout to respect the parent container and not overflow.
textview.setLayoutParams(new LayoutParams(LinearLayout.MATCH_PARENT,LinearLayout.WRAP_CONTENT));
int GeneralApproxWidthOfContainer = 400;
int GeneralApproxHeightOfContainer = 600;
textview.setMaxWidth(400);
textview.setMaxHeight(600);`
I got this error when I tried to write to a database on an Android system.
Apparently sqlite3 not only needs write permissions to the database file and the containing directory (as @austin-hyde already said in his answer) but also the environment variable TMPDIR
has to point to a (possibly writable) directory.
On my Android system I set it to TMPDIR="/data/local/tmp"
and now my script runs as expected :)
Edit:
If you can't set environment variables you can use one of the other methods listed here: https://www.sqlite.org/tempfiles.html#temporary_file_storage_locations
like PRAGMA temp_store_directory = 'directory-name';
