I help develop the Colectica for Excel addin, which opens SPSS and Stata data files in Excel. This does not require ODBC configuration; it reads the file and then inserts the data and metadata into your worksheet.
The addin is downloadable from http://www.colectica.com/software/colecticaforexcel
Paramiko supports SFTP. I've used it, and I've used Twisted. Both have their place, but you might find it easier to start with Paramiko.

$(".item").mouseover(function(){
$('.info').animate({ marginTop: '-50px' , opacity: 0.5 }, 1000);
});
In JUnit 5 you can inject TestInfo
which simplifies test meta data providing to test methods. For example:
@Test
@DisplayName("This is my test")
@Tag("It is my tag")
void test1(TestInfo testInfo) {
assertEquals("This is my test", testInfo.getDisplayName());
assertTrue(testInfo.getTags().contains("It is my tag"));
}
See more: JUnit 5 User guide, TestInfo javadoc.
It looks like most of post here described what you need here. However - something you might need more complex behavior - depending on what you're parsing. In your case it might be so that you won't need more complex parsing - but it depends what information you're extracting.
You can use regex groups as field name in class, after which could be written for example like this:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Reflection;
using System.Text.RegularExpressions;
public class Info
{
public String Identifier;
public char nextChar;
};
class testRegex {
const string input = "Lorem ipsum dolor sit %download%#456 amet, consectetur adipiscing %download%#3434 elit. " +
"Duis non nunc nec mauris feugiat porttitor. Sed tincidunt blandit dui a viverra%download%#298. Aenean dapibus nisl %download%#893434 id nibh auctor vel tempor velit blandit.";
static void Main(string[] args)
{
Regex regex = new Regex(@"%download%#(?<Identifier>[0-9]*)(?<nextChar>.)(?<thisCharIsNotNeeded>.)");
List<Info> infos = new List<Info>();
foreach (Match match in regex.Matches(input))
{
Info info = new Info();
for( int i = 1; i < regex.GetGroupNames().Length; i++ )
{
String groupName = regex.GetGroupNames()[i];
FieldInfo fi = info.GetType().GetField(regex.GetGroupNames()[i]);
if( fi != null ) // Field is non-public or does not exists.
fi.SetValue( info, Convert.ChangeType( match.Groups[groupName].Value, fi.FieldType));
}
infos.Add(info);
}
foreach ( var info in infos )
{
Console.WriteLine(info.Identifier + " followed by '" + info.nextChar.ToString() + "'");
}
}
};
This mechanism uses C# reflection to set value to class. group name is matched against field name in class instance. Please note that Convert.ChangeType won't accept any kind of garbage.
If you want to add tracking of line / column - you can add extra Regex split for lines, but in order to keep for loop intact - all match patterns must have named groups. (Otherwise column index will be calculated incorrectly)
This will results in following output:
456 followed by ' '
3434 followed by ' '
298 followed by '.'
893434 followed by ' '
Try change update="insTable:display"
to update="display"
. I believe you cannot prefix the id with the form ID like that.

NP-Complete means something very specific and you have to be careful or you will get the definition wrong. First, an NP problem is a yes/no problem such that
A problem X is NP-Complete if
If X is NP-complete and a deterministic, polynomial-time algorithm exists that can solve all instances of X correctly (0% false-positives, 0% false-negatives), then any problem in NP can be solved in deterministic-polynomial-time (by reduction to X).
So far, nobody has come up with such a deterministic polynomial-time algorithm, but nobody has proven one doesn't exist (there's a million bucks for anyone who can do either: the is the P = NP problem). That doesn't mean that you can't solve a particular instance of an NP-Complete (or NP-Hard) problem. It just means you can't have something that will work reliably on all instances of a problem the same way you could reliably sort a list of integers. You might very well be able to come up with an algorithm that will work very well on all practical instances of a NP-Hard problem.
You should move your switch into the template by using the 'ng-switch' directive:
module.directive('testForm', function() {
return {
restrict: 'E',
controllerAs: 'form',
controller: function ($scope) {
console.log("Form controller initialization");
var self = this;
this.fields = {};
this.addField = function(field) {
console.log("New field: ", field);
self.fields[field.name] = field;
};
}
}
});
module.directive('formField', function () {
return {
require: "^testForm",
template:
'<div ng-switch="field.fieldType">' +
' <span>{{title}}:</span>' +
' <input' +
' ng-switch-when="text"' +
' name="{{field.name}}"' +
' type="text"' +
' ng-model="field.value"' +
' />' +
' <select' +
' ng-switch-when="select"' +
' name="{{field.name}}"' +
' ng-model="field.value"' +
' ng-options="option for option in options">' +
' <option value=""></option>' +
' </select>' +
'</div>',
restrict: 'E',
replace: true,
scope: {
fieldType: "@",
title: "@",
name: "@",
value: "@",
options: "=",
},
link: function($scope, $element, $attrs, form) {
$scope.field = $scope;
form.addField($scope);
}
};
});
It can be use like this:
<test-form>
<div>
User '{{!form.fields.email.value}}' will be a {{!form.fields.role.value}}
</div>
<form-field title="Email" name="email" field-type="text" value="[email protected]"></form-field>
<form-field title="Role" name="role" field-type="select" options="['Cook', 'Eater']"></form-field>
<form-field title="Sex" name="sex" field-type="select" options="['Awesome', 'So-so', 'awful']"></form-field>
</test-form>
As mentioned in this tutorial, it's as simple as:
To install
brew install gradle
To upgrade
brew upgrade gradle
(using Homebrew of course)
Also see (finally) updated docs.
Cheers :)!
Set id in form when you submitting form
<form action="" id="cform">
<input type="submit" name="">
</form>
set in jquery
document.getElementById("cform").reset();
Just use the ID instead of the class?? I dont really understand why you would ask though when it looks like you know Jquery ?
$('#passwordsNoMatchRegister').show();
$('#passwordsNoMatchRegister').hide();
Give the child component a ref
and use $refs
to call a method on the child component directly.
html:
<div id="app">
<child-component ref="childComponent"></child-component>
<button @click="click">Click</button>
</div>
javascript:
var ChildComponent = {
template: '<div>{{value}}</div>',
data: function () {
return {
value: 0
};
},
methods: {
setValue: function(value) {
this.value = value;
}
}
}
new Vue({
el: '#app',
components: {
'child-component': ChildComponent
},
methods: {
click: function() {
this.$refs.childComponent.setValue(2.0);
}
}
})
For more info, see Vue documentation on refs.
you can also go for this.... this will only show the HTML section once javascript has loaded.
<!-- Adds the hidden style and removes it when javascript has loaded -->
<style type="text/css">
.hideAll {
visibility:hidden;
}
</style>
<script type="text/javascript">
$(window).load(function () {
$("#tabs").removeClass("hideAll");
});
</script>
<div id="tabs" class="hideAll">
##Content##
</div>
Ok guys I finally found out a good solution.
In your onCreate() in your activity housing your fragments add a backstack change listener like so:
fragmentManager.addOnBackStackChangedListener(new FragmentManager.OnBackStackChangedListener() {
@Override
public void onBackStackChanged() {
List<Fragment> f = fragmentManager.getFragments();
//List<Fragment> f only returns one value
Fragment frag = f.get(0);
currentFragment = frag.getClass().getSimpleName();
}
});
(Also adding my fragmenManager is declared in the activities O Now every time you change fragment the current fragment String will become the name of the current fragment. Then in the activities onBackPressed() you can control the actions of your back button as so:
@Override
public void onBackPressed() {
switch (currentFragment) {
case "FragmentOne":
// your code here
return;
case "FragmentTwo":
// your code here
return;
default:
fragmentManager.popBackStack();
// default action for any other fragment (return to previous)
}
}
I can confirm that this method works for me.
You mean something like this?
<?php
$jsonurl = "http://search.twitter.com/trends.json";
$json = file_get_contents($jsonurl,0,null,null);
$json_output = json_decode($json);
foreach ( $json_output->trends as $trend )
{
echo "{$trend->name}\n";
}
For anyone else that may encounter this problem and it is not solved by either of the options above, this is what worked for me.
1. Click on the website in IIS
2. Double Click on Authentication under IIS
3. Enable Anonymous Authentication
I had disabled this because we were using our own Auth, but that lead to this same problem and the accepted answer did not help in any way.
You can use the Unix-style -l
switch – typically terse and cryptic – or the equivalent --files-with-matches
– longer and more readable.
The output of grep --help
is not easy to read, but it's there:
-l, --files-with-matches print only names of FILEs containing matches
I do think requests
is the best option. Also note the possibility of setting encoding manually.
import requests
response = requests.get("http://www.gutenberg.org/files/10/10-0.txt")
# response.encoding = "utf-8"
hehe = response.text
function htmlEntities(str) {
return String(str).replace(/&/g, '&').replace(/</g, '<').replace(/>/g, '>').replace(/"/g, '"');
}
So then with var unsafestring = "<oohlook&atme>";
you would use htmlEntities(unsafestring);
Some interesting excerpts from the bash manpage:
When bash is invoked as an interactive login shell, or as a non-interactive shell with the
--login
option, it first reads and executes commands from the file/etc/profile
, if that file exists. After reading that file, it looks for~/.bash_profile
,~/.bash_login
, and~/.profile
, in that order, and reads and executes commands from the first one that exists and is readable. The--noprofile
option may be used when the shell is started to inhibit this behavior.
...
When an interactive shell that is not a login shell is started, bash reads and executes commands from/etc/bash.bashrc
and~/.bashrc
, if these files exist. This may be inhibited by using the--norc
option. The--rcfile
file option will force bash to read and execute commands from file instead of/etc/bash.bashrc
and~/.bashrc
.
So have a look at /etc/profile
or /etc/bash.bashrc
, these files are the right places for global settings. Put something like this in them to set up an environement variable:
export MY_VAR=xxx
Yes - different
chmod a+x
will add the exec bits to the file but will not touch other bits. For example file might be still unreadable to others
and group
.
chmod 755
will always make the file with perms 755
no matter what initial permissions were.
This may or may not matter for your script.
You can access the Image File and data from a form using MULTIPART FORM DATA By using the below code.
@POST
@Path("/UpdateProfile")
@Consumes(value={MediaType.APPLICATION_JSON,MediaType.MULTIPART_FORM_DATA})
@Produces(value={MediaType.APPLICATION_JSON,MediaType.APPLICATION_XML})
public Response updateProfile(
@FormDataParam("file") InputStream fileInputStream,
@FormDataParam("file") FormDataContentDisposition contentDispositionHeader,
@FormDataParam("ProfileInfo") String ProfileInfo,
@FormDataParam("registrationId") String registrationId) {
String filePath= "/filepath/"+contentDispositionHeader.getFileName();
OutputStream outputStream = null;
try {
int read = 0;
byte[] bytes = new byte[1024];
outputStream = new FileOutputStream(new File(filePath));
while ((read = fileInputStream.read(bytes)) != -1) {
outputStream.write(bytes, 0, read);
}
outputStream.flush();
outputStream.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
if (outputStream != null) {
try {
outputStream.close();
} catch(Exception ex) {}
}
}
}
You are exceeding the length of int datatype. You can use UNSIGNED attribute to support that value.
SIGNED INT can support till 2147483647 and with UNSIGNED INT allows double than this. After this you still want to save data than use CHAR or VARCHAR with length 10
I assume you mean list
and not array
? There is such a thing as an array in Python, but more often than not you want a list instead of an array.
The way to check if a list contains a value is to use in
:
if paid[j] in d:
# ...
How I did it:
final int numberOfSpaces = 22;
final char[] spaceArray = new char[numberOfSpaces];
Arrays.fill(spaces, ' ');
Now add it to your StringBuilder
stringBuilder.append(spaceArray);
or String
final String spaces = String.valueOf(spaceArray);
I recently discovered that using strtolower()
can cause issues where the data is truncated after a special character.
The solution was to use
mb_strtolower($string, 'UTF-8');
mb_ uses MultiByte. It supports more characters but in general is a little slower.
"toString()" is Very useful method which returns a string representation of an object. The "toString()" method returns a string reperentation an object.It is recommended that all subclasses override this method.
Declaration: java.lang.Object.toString()
Since, you have not mentioned which object you want to convert, so I am just using any object in sample code.
Integer integerObject = 5;
String convertedStringObject = integerObject .toString();
System.out.println(convertedStringObject );
You can find the complete code here. You can test the code here.
The shell provides some nice but hidden features because it's an interactive environment.
When you run commands from a javascript file via mongo commands.js you won't get quite identical behavior.
There are two ways around this.
(1) fake out the shell and make it think you are in interactive mode
$ mongo dbname << EOF > output.json
db.collection.find().pretty()
EOF
or
(2) use Javascript to translate the result of a find()
into a printable JSON
mongo dbname command.js > output.json
where command.js contains this (or its equivalent):
printjson( db.collection.find().toArray() )
This will pretty print the array of results, including [ ]
- if you don't want that you can iterate over the array and printjson()
each element.
By the way if you are running just a single Javascript statement you don't have to put it in a file and instead you can use:
$ mongo --quiet dbname --eval 'printjson(db.collection.find().toArray())' > output.json
Please run this below command from the console to skip the user table verification while launching mysql database from command prompt
mysqld -skip-grant-tables
Unicode escapes only work in unicode strings, so this
a="\u2026"
is actually a string of 6 characters: '\', 'u', '2', '0', '2', '6'.
To make unicode out of this, use decode('unicode-escape')
:
a="\u2026"
print repr(a)
print repr(a.decode('unicode-escape'))
## '\\u2026'
## u'\u2026'
We managed to get this working exactly as described in the OP, and hopefully someone else can make use of the solution. Here's what we did:
Set up the security context like so:
<security:http realm="Protected API" use-expressions="true" auto-config="false" create-session="stateless" entry-point-ref="CustomAuthenticationEntryPoint">
<security:custom-filter ref="authenticationTokenProcessingFilter" position="FORM_LOGIN_FILTER" />
<security:intercept-url pattern="/authenticate" access="permitAll"/>
<security:intercept-url pattern="/**" access="isAuthenticated()" />
</security:http>
<bean id="CustomAuthenticationEntryPoint"
class="com.demo.api.support.spring.CustomAuthenticationEntryPoint" />
<bean id="authenticationTokenProcessingFilter"
class="com.demo.api.support.spring.AuthenticationTokenProcessingFilter" >
<constructor-arg ref="authenticationManager" />
</bean>
As you can see, we've created a custom AuthenticationEntryPoint
, which basically just returns a 401 Unauthorized
if the request wasn't authenticated in the filter chain by our AuthenticationTokenProcessingFilter
.
CustomAuthenticationEntryPoint:
public class CustomAuthenticationEntryPoint implements AuthenticationEntryPoint {
@Override
public void commence(HttpServletRequest request, HttpServletResponse response,
AuthenticationException authException) throws IOException, ServletException {
response.sendError( HttpServletResponse.SC_UNAUTHORIZED, "Unauthorized: Authentication token was either missing or invalid." );
}
}
AuthenticationTokenProcessingFilter:
public class AuthenticationTokenProcessingFilter extends GenericFilterBean {
@Autowired UserService userService;
@Autowired TokenUtils tokenUtils;
AuthenticationManager authManager;
public AuthenticationTokenProcessingFilter(AuthenticationManager authManager) {
this.authManager = authManager;
}
@Override
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
@SuppressWarnings("unchecked")
Map<String, String[]> parms = request.getParameterMap();
if(parms.containsKey("token")) {
String token = parms.get("token")[0]; // grab the first "token" parameter
// validate the token
if (tokenUtils.validate(token)) {
// determine the user based on the (already validated) token
UserDetails userDetails = tokenUtils.getUserFromToken(token);
// build an Authentication object with the user's info
UsernamePasswordAuthenticationToken authentication =
new UsernamePasswordAuthenticationToken(userDetails.getUsername(), userDetails.getPassword());
authentication.setDetails(new WebAuthenticationDetailsSource().buildDetails((HttpServletRequest) request));
// set the authentication into the SecurityContext
SecurityContextHolder.getContext().setAuthentication(authManager.authenticate(authentication));
}
}
// continue thru the filter chain
chain.doFilter(request, response);
}
}
Obviously, TokenUtils
contains some privy (and very case-specific) code and can't be readily shared. Here's its interface:
public interface TokenUtils {
String getToken(UserDetails userDetails);
String getToken(UserDetails userDetails, Long expiration);
boolean validate(String token);
UserDetails getUserFromToken(String token);
}
That ought to get you off to a good start. Happy coding. :)
you need length() function
select length(customer_name) from ar.ra_customers
tl;dr: use OSX's native process launcher and manager, launchd
.
To do so, make a launchctl
daemon. You'll have full control over all aspects of the script. You can run once or keep alive as a daemon. In most cases, this is the way to go.
.plist
file according to the instructions in the Apple Dev docs here or more detail below.~/Library/LaunchAgents
launchctl load [filename.plist]
)For more on launchd
, the wikipedia article is quite good and describes the system and its advantages over other older systems.
Here's the specific plist file to run a script at login.
Updated 2017/09/25 for OSX El Capitan and newer (credit to José Messias Jr):
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Label</key>
<string>com.user.loginscript</string>
<key>ProgramArguments</key>
<array><string>/path/to/executable/script.sh</string></array>
<key>RunAtLoad</key>
<true/>
</dict>
</plist>
Replace the <string>
after the Program key with your desired command (note that any script referenced by that command must be executable: chmod a+x /path/to/executable/script.sh
to ensure it is for all users).
Save as ~/Library/LaunchAgents/com.user.loginscript.plist
Run launchctl load ~/Library/LaunchAgents/com.user.loginscript.plist
and log out/in to test (or to test directly, run launchctl start com.user.loginscript
)
Tail /var/log/system.log
for error messages.
The key is that this is a User-specific launchd entry, so it will be run on login for the given user. System-specific launch daemons (placed in /Library/LaunchDaemons
) are run on boot.
If you want a script to run on login for all users, I believe LoginHook is your only option, and that's probably the reason it exists.
If you want to initialize an array in a constructor, you can't use those array initializer like.
data= {10,20,30,40,50,60,71,80,90,91};
Just change it to
data = new int[] {10,20,30,40,50,60,71,80,90,91};
You don't have to specify the size with data[10] = new int[] { 10,...,91}
Just declare the property / field with int[] data;
and initialize it like above.
The corrected version of your code would look like the following:
public class Array {
int[] data;
public Array() {
data = new int[] {10,20,30,40,50,60,71,80,90,91};
}
}
As you see the bracket are empty. There isn't any need to tell the size between the brackets, because the initialization and its size are specified by the count of the elements between the curly brackets.
Sounds like you want to catch the DocumentCompleted event of your webbrowser control.
MSDN has a couple of good articles about the webbrowser control - WebBrowser Class has lots of examples, and How to: Add Web Browser Capabilities to a Windows Forms Application
And here is the non jQuery answer.
Fiddle: http://jsfiddle.net/J7m7m/7/
function changeText(value) {
document.getElementById('count').value = 500 * value;
}
HTML slight modification:
Product price: $500
<br>
Total price: $500
<br>
<input type="button" onclick="changeText(2)" value="2
Qty">
<input type="button" class="mnozstvi_sleva" value="4
Qty" onClick="changeText(4)">
<br>
Total <input type="text" id="count" value="1"/>
EDIT: It is very clear that this is a non-desired way as pointed out below (I had it coming). So in essence, this is how you would do it in plain old javascript. Most people would suggest you to use jQuery (other answer has the jQuery version) for good reason.
I faced the same challenge myself and found these 2 answers using flex
properties.

.container {
display: flex;
flex-direction: column;

}
i think i found what i need. maybe you can use charles proxy or slowy. hope it helps.
this is how to print whitespaces in python.
import string
string.whitespace
'\t\n\x0b\x0c\r '
i.e .
print "hello world"
print "Hello%sworld"%' '
print "hello", "world"
print "Hello "+"world
Just a small remark:
some Safari browsers do not seem to respect neither the "hidden" attribute nor the style setting "display:none" (tested with Safari 12.1 under MacOS 10.12.6). Without an explicit placeholder text, these browsers simply show an empty first line in the list of options. It may therefore be useful to always provide some explanatory text for this "dummy" entry:
<option hidden disabled selected value>(select an option)</option>
Thanks to the "disabled" attribute, it won't be actively selected anyway.
try ppretty:
from ppretty import ppretty
class Animal(object):
def __init__(self):
self.legs = 2
self.name = 'Dog'
self.color= 'Spotted'
self.smell= 'Alot'
self.age = 10
self.kids = 0
print ppretty(Animal(), seq_length=10)
Output:
__main__.Animal(age = 10, color = 'Spotted', kids = 0, legs = 2, name = 'Dog', smell = 'Alot')
You can use the following if you want to specify tricky formats:
df['date_col'] = pd.to_datetime(df['date_col'], format='%d/%m/%Y')
More details on format
here:
StringUtils.substringAfterLast("abcd: efg: 1006746", ": ") = "1006746";
As long as the format of the string is fixed you can use substringAfterLast.
<input onchange="readURL(this);" type="file" name="userfile" />
<img src="" id="viewImage"/>
<script>
function readURL(fileName) {
if (fileName.files && fileName.files[0]) {
var reader = new FileReader();
reader.onload = function (e) {
$('#viewImage')
.attr('src', e.target.result)
.width(150).height(200);
};
reader.readAsDataURL(fileName.files[0]);
}
}
</script>
This is the simple solution. This works for me.You can use the javascript print concept and simple save this as pdf.
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script type="text/javascript">
$("#btnPrint").live("click", function () {
var divContents = $("#dvContainer").html();
var printWindow = window.open('', '', 'height=400,width=800');
printWindow.document.write('<html><head><title>DIV Contents</title>');
printWindow.document.write('</head><body >');
printWindow.document.write(divContents);
printWindow.document.write('</body></html>');
printWindow.document.close();
printWindow.print();
});
</script>
</head>
<body>
<form id="form1">
<div id="dvContainer">
This content needs to be printed.
</div>
<input type="button" value="Print Div Contents" id="btnPrint" />
</form>
</body>
</html>
My case was that the server didn't accept the connection from this IP. The server is a SQL server from Google Apps Engine, and you have to configure allowed remote hosts that can connect to the server.
Adding the (new) host to the GAE admin page solved the issue.
You can use text
method:
$(function(){
$(".pushme").click(function () {
$(this).text(function(i, text){
return text === "PUSH ME" ? "DON'T PUSH ME" : "PUSH ME";
})
});
})
After many hours troubleshooting this stuff... Here are some quick highlights that helped us from the X-UA-Compatible
docs: http://msdn.microsoft.com/en-us/library/cc288325(VS.85).aspx#ctl00_contentContainer_ctl16
Using <meta http-equiv="X-UA-Compatible" content=" _______ " />
The Standard User Agent modes (the non-emulate ones) ignore <!DOCTYPE>
directives in your page and render based on the standards supported by that version of IE (e.g., IE=8
will better obey table border spacing and some pseudo selectors than IE=7
).
Whereas, the Emulate modes tell IE to follow any <!DOCTYPE>
directives in your page, rendering standards mode based the version you choose and quirks mode based on IE=5
Possible values for the content
attribute are:
content="IE=5"
content="IE=7"
content="IE=EmulateIE7"
content="IE=8"
content="IE=EmulateIE8"
content="IE=9"
content="IE=EmulateIE9"
content="IE=edge"
The easiest and purest method without relying on C headers is PyYaml (documentation), which can be installed via pip install pyyaml
:
#!/usr/bin/env python
import yaml
with open("example.yaml", 'r') as stream:
try:
print(yaml.safe_load(stream))
except yaml.YAMLError as exc:
print(exc)
And that's it. A plain yaml.load()
function also exists, but yaml.safe_load()
should always be preferred unless you explicitly need the arbitrary object serialization/deserialization provided in order to avoid introducing the possibility for arbitrary code execution.
Note the PyYaml project supports versions up through the YAML 1.1 specification. If YAML 1.2 specification support is needed, see ruamel.yaml as noted in this answer.
Quite old post, but it might help somebody new into git.

I've put this answer on a similar question that was marked as a duplicate of this question. The answer has helped a decent amount of people so I thought I'd add it here too in just in case.
This doesn't exactly answer the question but for anyone using AngularJS trying to achieve this, the answer is slightly different. And actually the normal answer won't work (at least it didn't for me).
Your html will look pretty similar to the normal radio button:
<input type='radio' name='group' ng-model='mValue' value='first' />First
<input type='radio' name='group' ng-model='mValue' value='second' /> Second
In your controller you'll have declared the mValue
that is associated with the radio buttons. To have one of these radio buttons preselected, assign the $scope
variable associated with the group to the desired input's value:
$scope.mValue="second"
This makes the "second" radio button selected on loading the page.
You were on the right track. IrfanView sets the background for transparency the same as the viewing color around the image.
You just need to re-open the image with IrfanView after changing the view color to white.
To change the viewing color in Irfanview go to:
Options > Properties/Settings > Viewing > Main window color
Airdroid , android market install the app on android then go onto the computer type in the address given, type in the password given (or scan the QR code). Go to settings and under security (if your running the new ICS or Jellybean) or go to settings->apps->managment and select unknown sources(for gingerbread) then click on (I think) speed install, or something along those lines. it will be on the top of the page slightly towards the left. drag and drop as many .apks as you want then on you android just tap the install buttons that appear. Airdroid is wonderful and does a lot more than just apks.

Use Swift closures :

var tapCallback: (() -> Void)?
@IBAction func didTap(_ sender: Any) {
tapCallback?()
}
}

let cell = tableView.dequeueReusableCell(withIdentifier: TheCell.identifier, for: indexPath) as! TheCell {
cell.tapCallback = {
//do stuff
}
return cell

}
I used interop to open Excel and to modify the column widths once the data was done. If you use interop to spit the data into a new Excel workbook (if this is what you want), it will be terribly slow. Instead, I generated a .CSV
, then opened the .CSV
in Excel. This has its own problems, but I've found this the quickest method.
First, convert the .CSV
:
// Convert array data into CSV format.
// Modified from http://csharphelper.com/blog/2018/04/write-a-csv-file-from-an-array-in-c/.
private string GetCSV(List<string> Headers, List<List<double>> Data)
{
// Get the bounds.
var rows = Data[0].Count;
var cols = Data.Count;
var row = 0;
// Convert the array into a CSV string.
StringBuilder sb = new StringBuilder();
// Add the first field in this row.
sb.Append(Headers[0]);
// Add the other fields in this row separated by commas.
for (int col = 1; col < cols; col++)
sb.Append("," + Headers[col]);
// Move to the next line.
sb.AppendLine();
for (row = 0; row < rows; row++)
{
// Add the first field in this row.
sb.Append(Data[0][row]);
// Add the other fields in this row separated by commas.
for (int col = 1; col < cols; col++)
sb.Append("," + Data[col][row]);
// Move to the next line.
sb.AppendLine();
}
// Return the CSV format string.
return sb.ToString();
}
Then, export it to Excel:
public void ExportToExcel()
{
// Initialize app and pop Excel on the screen.
var excelApp = new Excel.Application { Visible = true };
// I use unix time to give the files a unique name that's almost somewhat useful.
DateTime dateTime = DateTime.UtcNow;
long unixTime = ((DateTimeOffset)dateTime).ToUnixTimeSeconds();
var path = @"C:\Users\my\path\here + unixTime + ".csv";
var csv = GetCSV();
File.WriteAllText(path, csv);
// Create a new workbook and get its active sheet.
excelApp.Workbooks.Open(path);
var workSheet = (Excel.Worksheet)excelApp.ActiveSheet;
// iterate over each value and throw it in the chart
for (var column = 0; column < Data.Count; column++)
{
((Excel.Range)workSheet.Columns[column + 1]).AutoFit();
}
currentSheet = workSheet;
}
You'll have to install some stuff, too...
Right click on the solution from solution explorer and select "Manage NuGet Packages." - add Microsoft.Office.Interop.Excel
It might actually work right now if you created the project the way interop wants you to. If it still doesn't work, I had to create a new project in a different category. Under New > Project, select Visual C# > Windows Desktop > Console App. Otherwise, the interop tools won't work.
In case I forgot anything, here's my 'using' statements:
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using Excel = Microsoft.Office.Interop.Excel;
Private: It is an access specifier. By default the instance (member) variables or the methods of a class in c++/java are private. During inheritance, the code and the data are always inherited but is not accessible outside the class. We can declare our data members as private so that no one can make direct changes to our member variables and we can provide public getters and setters in order to change our private members. And this concept is always applied in the business rule.
Protected: It is also an access specifier. In C++, the protected members are accessible within the class and to the inherited class but not outside the class. In Java, the protected members are accessible within the class, to the inherited class as well as to all the classes within the same package.
You can install vim/vi for windows and set windows PATH variable and open it in command line.
I solved the problem by cat'ing all the pems together:
cat cert.pem chain.pem fullchain.pem >all.pem
openssl pkcs12 -export -in all.pem -inkey privkey.pem -out cert_and_key.p12 -name tomcat -CAfile chain.pem -caname root -password MYPASSWORD
keytool -importkeystore -deststorepass MYPASSWORD -destkeypass MYPASSWORD -destkeystore MyDSKeyStore.jks -srckeystore cert_and_key.p12 -srcstoretype PKCS12 -srcstorepass MYPASSWORD -alias tomcat
keytool -import -trustcacerts -alias root -file chain.pem -keystore MyDSKeyStore.jks -storepass MYPASSWORD
(keytool didn't know what to do with a PKCS7 formatted key)
I got all the pems from letsencrypt
header( "refresh:5;url=wherever.php" );
indeed you can use this code as teneff said, but you don't have to necessarily put the header before any sent output (this would output a "cannot relocate header.... :3 error").
To solve this use the php function ob_start();
before any html is outputed.
To terminate the ob just put ob_end_flush();
after you don't have any html output.
cheers!
The proper function is int fileno(FILE *stream)
. It can be found in <stdio.h>
, and is a POSIX standard but not standard C.
blog_development doesn't exist
You can see this in sql by the 0 rows affected
message
create it in mysql with
mysql> create database blog_development
However as you are using rails you should get used to using
$ rake db:create
to do the same task. It will use your database.yml file settings, which should include something like:
development:
adapter: mysql2
database: blog_development
pool: 5
Also become familiar with:
$ rake db:migrate # Run the database migration
$ rake db:seed # Run thew seeds file create statements
$ rake db:drop # Drop the database

Answer from italo is very good! However let me refine it a little:
function isEllipsisActive(e) {
var tolerance = 2; // In px. Depends on the font you are using
return e.offsetWidth + tolerance < e.scrollWidth;
}
If, in fact, you try the above code and use console.log
to print out the values of e.offsetWidth
and e.scrollWidth
, you will notice, on IE, that, even when you have no text truncation, a value difference of 1px
or 2px
is experienced.
So, depending on the font size you use, allow a certain tolerance!
I have a hunch that you have two ruby versions. Please paste the output of following command:
$ which -a ruby
updated regarding to the comment:
Nuke one version and leave only one. I had same problem with two versions looking at different locations for gems. Had me going crazy for few weeks. Put up a bounty here at SO got me same answer I'm giving to you.
All I did was nuke one installation of ruby and left the one managable via ports. I'd suggest doing this:
/usr
instead of /usr/local

Never parallelize an infinite stream with a limit. Here is what happens:
public static void main(String[] args) {
// let's count to 1 in parallel
System.out.println(
IntStream.iterate(0, i -> i + 1)
.parallel()
.skip(1)
.findFirst()
.getAsInt());
}
Result
Exception in thread "main" java.lang.OutOfMemoryError
at ...
at java.base/java.util.stream.IntPipeline.findFirst(IntPipeline.java:528)
at InfiniteTest.main(InfiniteTest.java:24)
Caused by: java.lang.OutOfMemoryError: Java heap space
at java.base/java.util.stream.SpinedBuffer$OfInt.newArray(SpinedBuffer.java:750)
at ...
Same if you use .limit(...)
Explanation here: Java 8, using .parallel in a stream causes OOM error
Similarly, don't use parallel if the stream is ordered and has much more elements than you want to process, e.g.
public static void main(String[] args) {
// let's count to 1 in parallel
System.out.println(
IntStream.range(1, 1000_000_000)
.parallel()
.skip(100)
.findFirst()
.getAsInt());
}
This may run much longer because the parallel threads may work on plenty of number ranges instead of the crucial one 0-100, causing this to take very long time.
What about this:
with open("your_csv_file.csv", "w") as f:
f.write("\n".join(text))
str.join() Return a string which is the concatenation of the strings in iterable. The separator between elements is the string providing this method.
if {le_gur_bond.gur1}="" or IsNull({le_gur_bond.gur1}) Then
""
else
"and " + {le_gur_bond.gur2} + " of "+ {le_gur_bond.grr_2_address2}
I implemented "ping" in pure Android Java and hosted it on gitlab. It does the same thing as the ping executable, but is much easier to configure. It's has a couple useful features like being able to bind to a given Network.
Or.. Pattern#quote
:
String[] value_split = rat_values.split(Pattern.quote("|"));
This is happening because String#split
accepts a regex:
|
has a special meaning in regex.
quote
will return a String representation for the regex.
You need to use javascript for this.
<form id="form1" action="showMessage.jsp" method="post">
<a href="javascript:;" onclick="document.getElementById('form1').submit();"><%=n%></a>
<input type="hidden" name="mess" value=<%=n%>/>

I suggest to use autotools
:
//##
Place generated object files (.o) into the same directory as their source files, in order to avoid collisions when non-recursive make is used.
AUTOMAKE_OPTIONS = subdir-objects
just including it in Makefile.am
with the other quite simple stuff.
Here is the tutorial.
You should to use: ConfigurableApplicationContext instead of for ApplicationContext
In case someone else runs accross this and wants to just disable all path variable changing for all users.
Access your sudoers file by using the command:visudo
. You should see the following line somewhere:
Defaults env_reset
which you should add the following on the next line
Defaults !secure_path
secure_path is enabled by default. This option specifies what to make $PATH when sudoing. The exclamation mark disables the feature.
IF EXISTS()
is semantically incorrect. EXISTS
condition can be used only inside a SQL statement. So you might rewrite your pl/sql block as follows:
declare
l_exst number(1);
begin
select case
when exists(select ce.s_regno
from courseoffering co
join co_enrolment ce
on ce.co_id = co.co_id
where ce.s_regno=403
and ce.coe_completionstatus = 'C'
and ce.c_id = 803
and rownum = 1
)
then 1
else 0
end into l_exst
from dual;
if l_exst = 1
then
DBMS_OUTPUT.put_line('YES YOU CAN');
else
DBMS_OUTPUT.put_line('YOU CANNOT');
end if;
end;
Or you can simply use count
function do determine the number of rows returned by the query, and rownum=1
predicate - you only need to know if a record exists:
declare
l_exst number;
begin
select count(*)
into l_exst
from courseoffering co
join co_enrolment ce
on ce.co_id = co.co_id
where ce.s_regno=403
and ce.coe_completionstatus = 'C'
and ce.c_id = 803
and rownum = 1;
if l_exst = 0
then
DBMS_OUTPUT.put_line('YOU CANNOT');
else
DBMS_OUTPUT.put_line('YES YOU CAN');
end if;
end;
You must set your query base to the DN of the user in question, then set your filter to the DN of the group you're wondering if they're a member of. To see if jdoe is a member of the office group then your query will look something like this:
ldapsearch -x -D "ldap_user" -w "user_passwd" -b "cn=jdoe,dc=example,dc=local" -h ldap_host '(memberof=cn=officegroup,dc=example,dc=local)'
If you want to see ALL the groups he's a member of, just request only the 'memberof' attribute in your search, like this:
ldapsearch -x -D "ldap_user" -w "user_passwd" -b "cn=jdoe,dc=example,dc=local" -h ldap_host **memberof**
From the side of ZIP archive structure - you can update zip file without recompressing it, you will just need to skip all files which are prior of the file you need to replace, then put your updated file, and then the rest of the files. And finally you'll need to put the updated centeral directory structure. However, I doubt that most common tools would allow you to make this.
Use the wildcard "#" but beware that at some point you will have to somehow understand the data passing through the bus!
You need to create the project on GitHub first. After that go to the project directory and run in terminal:
git init
git remote add origin https://github.com/xxx/yyy.git
git add .
git commit -m "first commit"
git push -u origin master
Ken has the right solution, but you don't want to add the picturebox.Image.Load() member method.
If you do it with a Load and the ImageLocation is not set, it will fail with a "Image Location must be set" exception. If you use the picturebox.Refresh() member method, it works without the exception.
Completed code below:
public void showAnimatedPictureBox(PictureBox thePicture)
{
thePicture.Image = Properties.Resources.hamster;
thePicture.Refresh();
thePicture.Visible = true;
}
It is invoked as: showAnimatedPictureBox( myPictureBox );

Replace:
myBinding.Source = ViewModel.SomeString;
with:
myBinding.Source = ViewModel;
Example:
Binding myBinding = new Binding();
myBinding.Source = ViewModel;
myBinding.Path = new PropertyPath("SomeString");
myBinding.Mode = BindingMode.TwoWay;
myBinding.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged;
BindingOperations.SetBinding(txtText, TextBox.TextProperty, myBinding);
Your source should be just ViewModel
, the .SomeString
part is evaluated from the Path
(the Path
can be set by the constructor or by the Path
property).
There are certain scenarios in which you can follow the steps suggested in the other answers, verify that Execution Policy is set correctly, and still have your scripts fail. If this happens to you, you are probably on a 64-bit machine with both 32-bit and 64-bit versions of PowerShell, and the failure is happening on the version that doesn't have Execution Policy set. The setting does not apply to both versions, so you have to explicitly set it twice.
Look in your Windows directory for System32 and SysWOW64.
Repeat these steps for each directory:
Check the current setting for ExecutionPolicy:
Get-ExecutionPolicy -List
Set the ExecutionPolicy for the level and scope you want, for example:
Set-ExecutionPolicy -Scope LocalMachine Unrestricted
Note that you may need to run PowerShell as administrator depending on the scope you are trying to set the policy for.
You can read a lot more here: Running Windows PowerShell Scripts
As far as I can see everything is right with your code. Your error is:
SMTP Error: Could not authenticate.
Which means that the credentials you've sending are rejected by the SMTP server. Make sure the host, port, username and password are good.
If you want to use STARTTLS, try adding:
$mail->SMTPSecure = 'tls';
If you want to use SMTPS (SSL), try adding:
$mail->SMTPSecure = 'ssl';
Keep in mind that:
Maybe this example can help (GMail secure SMTP).

Unlike C, Java allows using the % for both integer and floating point and (unlike C89 and C++) it is well-defined for all inputs (including negatives):
From JLS §15.17.3:
The result of a floating-point remainder operation is determined by the rules of IEEE arithmetic:
- If either operand is NaN, the result is NaN.
- If the result is not NaN, the sign of the result equals the sign of the dividend.
- If the dividend is an infinity, or the divisor is a zero, or both, the result is NaN.
- If the dividend is finite and the divisor is an infinity, the result equals the dividend.
- If the dividend is a zero and the divisor is finite, the result equals the dividend.
- In the remaining cases, where neither an infinity, nor a zero, nor NaN is involved, the floating-point remainder r from the division of a dividend n by a divisor d is defined by the mathematical relation r=n-(d·q) where q is an integer that is negative only if n/d is negative and positive only if n/d is positive, and whose magnitude is as large as possible without exceeding the magnitude of the true mathematical quotient of n and d.
So for your example, 0.5/0.3 = 1.6... . q has the same sign (positive) as 0.5 (the dividend), and the magnitude is 1 (integer with largest magnitude not exceeding magnitude of 1.6...), and r = 0.5 - (0.3 * 1) = 0.2

According to bootstrap's documentation, the class is used to hide information intended only for screen readers from the layout of the rendered page.
Screen readers will have trouble with your forms if you don't include a label for every input. For these inline forms, you can hide the labels using the .sr-only class.
Here is an example styling used:
.sr-only {
position: absolute;
width: 1px;
height: 1px;
padding: 0;
margin: -1px;
overflow: hidden;
clip: rect(0,0,0,0);
border: 0;
}
Is it important or can I remove it? Works fine without.
It's important, don't remove it.
You should always consider screen readers for accessibility purposes. Usage of the class will hide the element anyways, therefore you shouldn't see a visual difference.
If you're interested in reading about accessibility:
If you don't insist on using pure Javascript, you can build a sequential code in Livescript and it looks pretty good. You might want to take a look at this example:
# application
do
i = 3
console.log td!, "start"
<- :lo(op) ->
console.log td!, "hi #{i}"
i--
<- wait-for \something
if i is 0
return op! # break
lo(op)
<- sleep 1500ms
<- :lo(op) ->
console.log td!, "hello #{i}"
i++
if i is 3
return op! # break
<- sleep 1000ms
lo(op)
<- sleep 0
console.log td!, "heyy"
do
a = 8
<- :lo(op) ->
console.log td!, "this runs in parallel!", a
a--
go \something
if a is 0
return op! # break
<- sleep 500ms
lo(op)
Output:
0ms : start
2ms : hi 3
3ms : this runs in parallel! 8
3ms : hi 2
505ms : this runs in parallel! 7
505ms : hi 1

Instead of doing a chmod
to your user, it gives the admin
group (to which you presumably belong) write access to the specific directories in /usr/local
that homebrew uses. It also tells you exactly what it intends to do before doing it.
Here is the documentation. That should tell you what it means and what to do with them. You should avoid using the numeric value and use the constants listed there as well, as the number may change between different systems.
I'm running tomcat7 on CentOS 6.6. I tried creating a new /usr/share/tomcat/bin/setenv.sh file and setting both JAVA_OPTS
and CATALINA_OPTS
. But tomcat wouldn't pick up the values on restart. When I put the following line into /etc/tomcat/tomcat.conf:
CATALINA_OPTS="-Xms128m -Xmx1024m -XX:MaxPermSize=1024m"
tomcat did pick up the new environment variable. I verified this by running
ps aux | grep tomcat
and seeing the new settings in the output. This took a long time to diagnose and I didn't see anyone else suggesting this, so I thought I'd throw it out to the internet community.
You may try this example:
<form>_x000D_
<h1>Hello! I'm duke! What's you name?</h1>_x000D_
<input type="text" name="user">_x000D_
<br>_x000D_
<br>_x000D_
<input type="submit" value="submit"> _x000D_
<input type="reset">_x000D_
</form>_x000D_
<h1>Hello ${param.user}</h1> _x000D_
<!-- its Expression Language -->
_x000D_
The parenthesis are superfluous in your example. The pointer doesn't care whether there's an array involved - it only knows that its pointing to an int
int g[] = {9,8};
int (*j) = g;
could also be rewritten as
int g[] = {9,8};
int *j = g;
which could also be rewritten as
int g[] = {9,8};
int *j = &g[0];
a pointer-to-an-array would look like
int g[] = {9,8};
int (*j)[2] = &g;
//Dereference 'j' and access array element zero
int n = (*j)[0];
There's a good read on pointer declarations (and how to grok them) at this link here: http://www.codeproject.com/Articles/7042/How-to-interpret-complex-C-C-declarations

When you add an object to $stateProvider.state
that object is then passed with the state. So you can add additional properties which you can read later on when needed.
Example route configuration
$stateProvider
.state('public', {
abstract: true,
module: 'public'
})
.state('public.login', {
url: '/login',
module: 'public'
})
.state('tool', {
abstract: true,
module: 'private'
})
.state('tool.suggestions', {
url: '/suggestions',
module: 'private'
});
The $stateChangeStart
event gives you acces to the toState
and fromState
objects. These state objects will contain the configuration properties.
Example check for the custom module property
$rootScope.$on('$stateChangeStart', function(e, toState, toParams, fromState, fromParams) {
if (toState.module === 'private' && !$cookies.Session) {
// If logged out and transitioning to a logged in page:
e.preventDefault();
$state.go('public.login');
} else if (toState.module === 'public' && $cookies.Session) {
// If logged in and transitioning to a logged out page:
e.preventDefault();
$state.go('tool.suggestions');
};
});
I didn't change the logic of the cookies because I think that is out of scope for your question.
You can create a Helper to get you this to work more modular.
Value publicStates
myApp.value('publicStates', function(){
return {
module: 'public',
routes: [{
name: 'login',
config: {
url: '/login'
}
}]
};
});
Value privateStates
myApp.value('privateStates', function(){
return {
module: 'private',
routes: [{
name: 'suggestions',
config: {
url: '/suggestions'
}
}]
};
});
The Helper
myApp.provider('stateshelperConfig', function () {
this.config = {
// These are the properties we need to set
// $stateProvider: undefined
process: function (stateConfigs){
var module = stateConfigs.module;
$stateProvider = this.$stateProvider;
$stateProvider.state(module, {
abstract: true,
module: module
});
angular.forEach(stateConfigs, function (route){
route.config.module = module;
$stateProvider.state(module + route.name, route.config);
});
}
};
this.$get = function () {
return {
config: this.config
};
};
});
Now you can use the helper to add the state configuration to your state configuration.
myApp.config(['$stateProvider', '$urlRouterProvider',
'stateshelperConfigProvider', 'publicStates', 'privateStates',
function ($stateProvider, $urlRouterProvider, helper, publicStates, privateStates) {
helper.config.$stateProvider = $stateProvider;
helper.process(publicStates);
helper.process(privateStates);
}]);
This way you can abstract the repeated code, and come up with a more modular solution.
Note: the code above isn't tested
In Java, classes you write are Objects. Constructors construct those objects. For example if I have an Apple.class
like so:
public class Apple {
//instance variables
String type; // macintosh, green, red, ...
/**
* This is the default constructor that gets called when you use
* Apple a = new Apple(); which creates an Apple object named a.
*/
public Apple() {
// in here you initialize instance variables, and sometimes but rarely
// do other functionality (at least with basic objects)
this.type = "macintosh"; // the 'this' keyword refers to 'this' object. so this.type refers to Apple's 'type' instance variable.
}
/**
* this is another constructor with a parameter. You can have more than one
* constructor as long as they have different parameters. It creates an Apple
* object when called using Apple a = new Apple("someAppleType");
*/
public Apple(String t) {
// when the constructor is called (i.e new Apple() ) this code is executed
this.type = t;
}
/**
* methods in a class are functions. They are whatever functionality needed
* for the object
*/
public String someAppleRelatedMethod(){
return "hello, Apple class!";
}
public static void main(String[] args) {
// construct an apple
Apple a = new Apple("green");
// 'a' is now an Apple object and has all the methods and
// variables of the Apple class.
// To use a method from 'a':
String temp = a.someAppleRelatedMethod();
System.out.println(temp);
System.out.println("a's type is " + a.type);
}
}
Hopefully I explained everything in the comments of the code, but here is a summary: Constructors 'construct' an object of type of the class. The constructor must be named the same thing as the class. They are mostly used for initializing instance varibales Methods are functionality of the objects.
And there it is... right under my nose:
From the react docs themselves: https://facebook.github.io/react/docs/reusable-components.html
// An array of a certain type
optionalArrayOf: React.PropTypes.arrayOf(React.PropTypes.number),
Simply use bootstrap-multiselect where you can populate dropdown with multiselect option and many more feaatures.
For doc and tutorials you may visit below link
final
can be used to mark a variable "unchangeable"
private final String name = "foo"; //the reference name can never change
final
can also make a method not "overrideable"
public final String toString() { return "NULL"; }
final
can also make a class not "inheritable". i.e. the class can not be subclassed.
public final class finalClass {...}
public class classNotAllowed extends finalClass {...} // Not allowed
finally
is used in a try/catch statement to execute code "always"
lock.lock();
try {
//do stuff
} catch (SomeException se) {
//handle se
} finally {
lock.unlock(); //always executed, even if Exception or Error or se
}
Java 7 has a new try with resources statement that you can use to automatically close resources that explicitly or implicitly implement java.io.Closeable or java.lang.AutoCloseable
finalize
is called when an object is garbage collected. You rarely need to override it. An example:
protected void finalize() {
//free resources (e.g. unallocate memory)
super.finalize();
}
Usually before installing a package one has to know its exact name:
# define a string to search
export to_srch=perl
# get html output of search and pick only the cygwin package names
wget -qO- "https://cygwin.com/cgi-bin2/package-grep.cgi?grep=$to_srch&arch=x86_64" | \
perl -l -ne 'm!(.*?)<\/a>\s+\-(.*?)\:(.*?)<\/li>!;print $2'
# and install
# install multiple packages at once, note the
setup-x86_64.exe -q -s http://cygwin.mirror.constant.com -P "<<chosen_package_name>>"
You can use indexOf(). Like:
var Color = ["blue", "black", "brown", "gold"];
var a = Color.indexOf("brown");
alert(a);
The indexOf() method searches the array for the specified item, and returns its position. And return -1 if the item is not found.
If you want to search from end to start, use the lastIndexOf() method:
var Color = ["blue", "black", "brown", "gold"];
var a = Color.lastIndexOf("brown");
alert(a);
The search will start at the specified position, or at the end if no start position is specified, and end the search at the beginning of the array.
Returns -1 if the item is not found.
It's also possible to get this error if you are running the test project using JUnit instead of Android JUnit. Naturally, the solution is just to change how you run it.
SqlCommand yourCommand = new SqlCommand();
yourCommand.Connection = yourSqlConn;
yourCommand.Parameters.Add("@yourParam");
yourCommand.Parameters["@yourParam"].Direction = ParameterDirection.Output;
// execute your query successfully
int yourResult = yourCommand.Parameters["@yourParam"].Value;
This is where the window function row_number()
comes in handy:
SELECT s.siteName, s.siteIP, h.date
FROM sites s INNER JOIN
(select h.*, row_number() over (partition by siteName order by date desc) as seqnum
from history h
) h
ON s.siteName = h.siteName and seqnum = 1
ORDER BY s.siteName, h.date
For those who are still coming for solution here, the easiest solution would be to use <wsdlLocation>
, without changing any code. Working steps are given below:
src/main/resource
In pom file, add both wsdlDirectory and wsdlLocation(don't miss / at the beginning of wsdlLocation), like below. While wsdlDirectory is used to generate code and wsdlLocation is used at runtime to create dynamic proxy.
<wsdlDirectory>src/main/resources/mydir</wsdlDirectory>
<wsdlLocation>/mydir/my.wsdl</wsdlLocation>
Then in your java code(with no-arg constructor):
MyPort myPort = new MyPortService().getMyPort();

The List
interface supports random access via the get
method - to get line 0, use list.get(0)
. You'll need to use array access on that, ie, lines.get(0)[0]
is the first element of the first line.
See the javadoc here.
Note that Git 1.9/2.0 (Q1 2014) has removed that limitation.
See commit 82fba2b, from Nguy?n Thái Ng?c Duy (pclouds
):
Now that git supports data transfer from or to a shallow clone, these limitations are not true anymore.
--depth <depth>::
Create a 'shallow' clone with a history truncated to the specified number of revisions.
That stems from commits like 0d7d285, f2c681c, and c29a7b8 which support clone, send-pack /receive-pack with/from shallow clones.
smart-http now supports shallow fetch/clone too.
All the details are in "shallow.c
: the 8 steps to select new commits for .git/shallow
".
Update June 2015: Git 2.5 will even allow for fetching a single commit!
(Ultimate shallow case)
Update January 2016: Git 2.8 (Mach 2016) now documents officially the practice of getting a minimal history.
See commit 99487cf, commit 9cfde9e (30 Dec 2015), commit 9cfde9e (30 Dec 2015), commit bac5874 (29 Dec 2015), and commit 1de2e44 (28 Dec 2015) by Stephen P. Smith (``).
(Merged by Junio C Hamano -- gitster
-- in commit 7e3e80a, 20 Jan 2016)
This is "Documentation/user-manual.txt
"
A
<<def_shallow_clone,shallow clone>>
is created by specifying thegit-clone --depth
switch.
The depth can later be changed with thegit-fetch --depth
switch, or full history restored with--unshallow
.Merging inside a
<<def_shallow_clone,shallow clone>>
will work as long as a merge base is in the recent history.
Otherwise, it will be like merging unrelated histories and may have to result in huge conflicts.
This limitation may make such a repository unsuitable to be used in merge based workflows.
Update 2020:
git fetch --shallow-exclude=
to prevent fetching all historygit fetch --shallow-since=
to prevent fetching old commits.For more on the shallow clone update process, see "How to update a git shallow clone?".
As commented by Richard Michael:
to backfill history:
git pull --unshallow
And Olle Härstedt adds in the comments:
To backfill part of the history:
git fetch --depth=100
.
I had this issue today on a repo.
It wasn't the +refs/heads/*:refs/remotes/origin/*
issue as per top solution.
Symptom was simply that git fetch origin
or git fetch
just didn't appear to do anything, although there were remote branches to fetch.
After trying lots of things, I removed the origin remote, and recreated it. That seems to have fixed it. Don't know why.
remove with:
git remote rm origin
and recreate with:
git remote add origin <git uri>
If you are using Docker toolkit on window 10 home you will need to access the webpage through docker-machine ip command. It is generally 192.168.99.100:
It is assumed that you are running with publish command like below.
docker run -it -p 8080:8080 demo
With Window 10 pro version you can access with localhost or corresponding loopback 127.0.0.1:8080 etc (Tomcat or whatever you wish). This is because you don't have a virtual box there and docker is running directly on Window Hyper V and loopback is directly accessible.
Verify the hosts file in window for any digression. It should have 127.0.0.1 mapped to localhost
Suppose you have two lists:
Id Value
1 A
2 B
3 C
Id ChildValue
1 a1
1 a2
1 a3
2 b1
2 b2
When you Join
the two lists on the Id
field the result will be:
Value ChildValue
A a1
A a2
A a3
B b1
B b2
When you GroupJoin
the two lists on the Id
field the result will be:
Value ChildValues
A [a1, a2, a3]
B [b1, b2]
C []
So Join
produces a flat (tabular) result of parent and child values.
GroupJoin
produces a list of entries in the first list, each with a group of joined entries in the second list.
That's why Join
is the equivalent of INNER JOIN
in SQL: there are no entries for C
. While GroupJoin
is the equivalent of OUTER JOIN
: C
is in the result set, but with an empty list of related entries (in an SQL result set there would be a row C - null
).
So let the two lists be IEnumerable<Parent>
and IEnumerable<Child>
respectively. (In case of Linq to Entities: IQueryable<T>
).
Join
syntax would be
from p in Parent
join c in Child on p.Id equals c.Id
select new { p.Value, c.ChildValue }
returning an IEnumerable<X>
where X is an anonymous type with two properties, Value
and ChildValue
. This query syntax uses the Join
method under the hood.
GroupJoin
syntax would be
from p in Parent
join c in Child on p.Id equals c.Id into g
select new { Parent = p, Children = g }
returning an IEnumerable<Y>
where Y is an anonymous type consisting of one property of type Parent
and a property of type IEnumerable<Child>
. This query syntax uses the GroupJoin
method under the hood.
We could just do select g
in the latter query, which would select an IEnumerable<IEnumerable<Child>>
, say a list of lists. In many cases the select with the parent included is more useful.
As said, the statement ...
from p in Parent
join c in Child on p.Id equals c.Id into g
select new { Parent = p, Children = g }
... produces a list of parents with child groups. This can be turned into a flat list of parent-child pairs by two small additions:
from p in parents
join c in children on p.Id equals c.Id into g // <= into
from c in g.DefaultIfEmpty() // <= flattens the groups
select new { Parent = p.Value, Child = c?.ChildValue }
The result is similar to
Value Child
A a1
A a2
A a3
B b1
B b2
C (null)
Note that the range variable c
is reused in the above statement. Doing this, any join
statement can simply be converted to an outer join
by adding the equivalent of into g from c in g.DefaultIfEmpty()
to an existing join
statement.
This is where query (or comprehensive) syntax shines. Method (or fluent) syntax shows what really happens, but it's hard to write:
parents.GroupJoin(children, p => p.Id, c => c.Id, (p, c) => new { p, c })
.SelectMany(x => x.c.DefaultIfEmpty(), (x,c) => new { x.p.Value, c?.ChildValue } )
So a flat outer join
in LINQ is a GroupJoin
, flattened by SelectMany
.
Suppose the list of parents is a bit longer. Some UI produces a list of selected parents as Id
values in a fixed order. Let's use:
var ids = new[] { 3,7,2,4 };
Now the selected parents must be filtered from the parents list in this exact order.
If we do ...
var result = parents.Where(p => ids.Contains(p.Id));
... the order of parents
will determine the result. If the parents are ordered by Id
, the result will be parents 2, 3, 4, 7. Not good. However, we can also use join
to filter the list. And by using ids
as first list, the order will be preserved:
from id in ids
join p in parents on id equals p.Id
select p
The result is parents 3, 7, 2, 4.
Why not consider creating your data class(es) as just a subclassed XmlDocument, then you get all of that for free. You don't need to serialize or create any off-doc nodes at all, and you get structure you want.
If you want to make it more sophisticated, write a base class that is a subclass of XmlDocument, then give it basic accessors, and you're set.

When attempting to export data using the accepted answer I got an error:
ERROR 1235 (42000) at line 3367: This version of MySQL doesn't yet support 'multiple triggers with the same action time and event for one table'
As mentioned above:
mysqldump --no-create-info
Will export the data but it will also export the create trigger statements. If like me your outputting database structure (which also includes triggers) with one command and then using the above command to get the data you should also use '--skip-triggers'.
So if you want JUST the data:
mysqldump --no-create-info --skip-triggers

Can't hurt to post another view since there's still not an official way to do this. Wrote a lightweight jQuery plugin with which you can define a background radial gradient and a transition speed. This basic usage will then let it fade in, optimised with requestAnimationFrame (very smooth) :
$('#element').gradientFade({
duration: 2000,
from: '(20,20,20,1)',
to: '(120,120,120,0)'
});

Keeps original background and all properties intact. Also has highlight tracking as a setting :

You can use normal CSS selectors to select an element by name using jquery. Like this:
Button Code
<button type="button" name="mybutton">Click Me!</button>
Selector & Event Bind Code
$("button[name='mybutton']").click(function() {});

It's the same. Your international format is already correct, and is recommended for use in all cases, where possible.
Instead of parsing it manually it's better to use pathinfo function:
$path_parts = pathinfo($value);
$extension = strtolower($path_parts['extension']);
$fileName = $path_parts['filename'];
Run SHOW CREATE TABLE <table name>
query.
I suggest going straight for the model approach in Swing. After you've put the component in the panel and layout manager, don't even bother keeping a specific reference to it.
If you really want the widget, then you can test each with isSelected
, or maintain a Map<ButtonModel,JRadioButton>
.
A major practical difference is its use:
in security scenario
where we always needed a new session, we should use request.getSession(true)
.
request.getSession(false): will return null if no session found.
C# equivalent of your code is
class Imagedata : PDFStreamEngine
{
// C# uses "base" keyword whenever Java uses "super"
// so instead of super(...) in Java we should call its C# equivalent (base):
public Imagedata()
: base(ResourceLoader.loadProperties("org/apache/pdfbox/resources/PDFTextStripper.properties", true))
{ }
// Java methods are virtual by default, when C# methods aren't.
// So we should be sure that processOperator method in base class
// (that is PDFStreamEngine)
// declared as "virtual"
protected override void processOperator(PDFOperator operations, List arguments)
{
base.processOperator(operations, arguments);
}
}
this worked for me on Ubuntu 20.04 with mysql 8, the weird hashing thing is because the native PASSWORD() function was removed in mysql 8 (or earlier?)
UPDATE mysql.user SET
plugin = 'mysql_native_password',
Host = '%',
authentication_string = CONCAT('*', UPPER(SHA1(UNHEX(SHA1('insert password here')))))
WHERE User = 'root';

For OpenGL rendering with the Nvidia driver, use the following image:

For other OpenGL implementations, make sure the image has the same implementation as the host.
You might consider this Open Source tool, matiri, https://github.com/AAFC-MBB/matiri which is a concurrent mysql backup script with metadata in Sqlite3. Features:

Do you mean something like this:

If you are looking for a hard limit across all uploads on the site, you can limit these in php.ini by setting the following:
`upload_max_filesize = 2M` `post_max_size = 2M`
that will set the maximum upload limit to 2 MB
I spent a day messing with CSS before I found anataliocs tip. Add wmode=transparent
as a parameter to the YouTube URL:
<iframe title=<your frame title goes here>
src="http://www.youtube.com/embed/K3j9taoTd0E?wmode=transparent"
scrolling="no"
frameborder="0"
width="640"
height="390"
style="border:none;">
</iframe>
This allows the iframe to inherit the z-index of its container so your opaque <div>
would be in front of the iframe.
If you want to easily connect your device to run, debug or deploy your Android apps over WiFi you can use an open source IntelliJ Plugin I've developed. Here is the code and here the plugin ready to be used.
The usage is quite simple. Here you have a gif:
Completely Transparent StatusBar and NavigationBar
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
transparentStatusAndNavigation();
}
private void transparentStatusAndNavigation() {
//make full transparent statusBar
if (Build.VERSION.SDK_INT >= 19 && Build.VERSION.SDK_INT < 21) {
setWindowFlag(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS
| WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION, true);
}
if (Build.VERSION.SDK_INT >= 19) {
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
);
}
if (Build.VERSION.SDK_INT >= 21) {
setWindowFlag(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS
| WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION, false);
getWindow().setStatusBarColor(Color.TRANSPARENT);
getWindow().setNavigationBarColor(Color.TRANSPARENT);
}
}
private void setWindowFlag(final int bits, boolean on) {
Window win = getWindow();
WindowManager.LayoutParams winParams = win.getAttributes();
if (on) {
winParams.flags |= bits;
} else {
winParams.flags &= ~bits;
}
win.setAttributes(winParams);
}
Also, this error gets fixed if the package you're trying to use has it's own type file(s) and it's listed it in the package.json typings
attribute
Like so:
{
"name": "some-package",
"version": "X.Y.Z",
"description": "Yada yada yada",
"main": "./index.js",
"typings": "./index.d.ts",
"repository": "https://github.com/yadayada.git",
"author": "John Doe",
"license": "MIT",
"private": true
}
For starters you aren't iterating over the result list properly, you are not using the index i at all. Try something like this:
List<Object> list = getHouseInfo();
for (int i=0; i<list.size; i++){
System.out.println("Element "+i+list.get(i));
}
It looks like the query reutrns a List of Arrays of Objects, because Arrays are not proper objects that override toString you need to do a cast first and then use Arrays.toString().
List<Object> list = getHouseInfo();
for (int i=0; i<list.size; i++){
Object[] row = (Object[]) list.get(i);
System.out.println("Element "+i+Arrays.toString(row));
}
This is because, the amount of memory you wish to assign for JVM is not available or may be you are assigning more than available memory. Try small size then u can see the difference.
Try:
set JAVA_OPTS=-Xms128m -Xmx512m -XX:PermSize=128m
I had the same problem and it was related to the .gitattributes
file.
However the file type that caused the problem was not specified in the .gitattributes
.
I was able to solve the issue by simply running
git rm .gitattributes
git add -A
git reset --hard
In my case, the problem was I didn't had a Tomcat server separately installed in my eclipse. I assumed my Springboot will start the server automatically within itself.
Since my main class extends SpringBootServletInitializer
and override configure
method, I definitely need a Tomcat server installed in my IDE.
To install, first download Apachce Tomcat (version 9 in my case) and create server using Servers tab.
After installation, run the main class on server.
Run As -> Run on Server
Try this:
select * from your_table
where date >= '2020-10-01'
Based on the answers already provided here, this is the way I implemented it:
JFrame frame= new JFrame()
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
// frame stuffs here ...
frame.dispatchEvent(new WindowEvent(frame, WindowEvent.WINDOW_CLOSING));
The JFrame gets the event to close and upon closing, exits.
Today I found another situation when this problem occures - when you have several JDK, defined in JAVA_PATH. I have:
JAVA_HOME = C:\JAVA\JDK\jdk1.6.0_38;C:\JAVA\JDK\jdk1.7.0_10
So I received this problem with Android Studio setup
But when I've removed one of JDK - problem has been solved:
JAVA_HOME = C:\JAVA\JDK\jdk1.7.0_10
Installation wisard found my jdk and i had a nice night to study studio.
But unfortunatelly even installed studio doesn't work with several jdk. Does anybody know how to fix it?
I hope I've helped someone
You can revert a commit using git revert HEAD^
for reverting to the next-to-last commit. You can also specify the commit to revert using the id instead of HEAD^
does anyone have a better way?
I think just adding the script to the body would be easier then adding it to the last node on the page. How about this:
function include(url) {
var s = document.createElement("script");
s.setAttribute("type", "text/javascript");
s.setAttribute("src", url);
document.body.appendChild(s);
}
I resorted to creating 2 style cascades using inline-block for input that pretty much override the field:
.input-sm {
height: 2.1em;
display: inline-block;
}
and a series of fixed sizes as opposed to %
.input-10 {
width: 10em;
}
.input-32 {
width: 32em;
}
They are used for formatting strings. %s
acts a placeholder for a string while %d
acts as a placeholder for a number. Their associated values are passed in via a tuple using the %
operator.
name = 'marcog'
number = 42
print '%s %d' % (name, number)
will print marcog 42
. Note that name is a string (%s) and number is an integer (%d for decimal).
See https://docs.python.org/3/library/stdtypes.html#printf-style-string-formatting for details.
In Python 3 the example would be:
print('%s %d' % (name, number))
Well According to a comment on the shuf answer he shuffed 78 000 000 000 lines in under a minute.
Challenge accepted...
EDIT: I beat my own record
$ time ./powershuf.py -n 10 --file lines_78000000000.txt > /dev/null
./powershuf.py -n 10 --file lines_78000000000.txt > /dev/null 0.02s user 0.01s system 80% cpu 0.047 total
The reason it is so fast, well I don't read the whole file and just move the file pointer 10 times and print the line after the pointer.
First I needed a file of 78.000.000.000 lines:
seq 1 78 | xargs -n 1 -P 16 -I% seq 1 1000 | xargs -n 1 -P 16 -I% echo "" > lines_78000.txt
seq 1 1000 | xargs -n 1 -P 16 -I% cat lines_78000.txt > lines_78000000.txt
seq 1 1000 | xargs -n 1 -P 16 -I% cat lines_78000000.txt > lines_78000000000.txt
This gives me a a file with 78 Billion newlines ;-)
Now for the shuf part:
$ time shuf -n 10 lines_78000000000.txt
shuf -n 10 lines_78000000000.txt 2171.20s user 22.17s system 99% cpu 36:35.80 total
The bottleneck was CPU and not using multiple threads, it pinned 1 core at 100% the other 15 were not used.
Python is what I regularly use so that's what I'll use to make this faster:
#!/bin/python3
import random
f = open("lines_78000000000.txt", "rt")
count = 0
while 1:
buffer = f.read(65536)
if not buffer: break
count += buffer.count('\n')
for i in range(10):
f.readline(random.randint(1, count))
This got me just under a minute:
$ time ./shuf.py
./shuf.py 42.57s user 16.19s system 98% cpu 59.752 total
I did this on a Lenovo X1 extreme 2nd gen with the i9 and Samsung NVMe which gives me plenty read and write speed.
I know it can get faster but I'll leave some room to give others a try.

I needed to solve this in VB.NET. Here's what I've got that seems to work:
Private Sub ComboBox1_SelectionChanged(ByVal sender As System.Object, ByVal e As System.Windows.Controls.SelectionChangedEventArgs) Handles ComboBox_AllSites.SelectionChanged
Dim cr As System.Windows.Controls.ComboBoxItem = ComboBox1.SelectedValue
Dim currentText = cr.Content
MessageBox.Show(currentText)
End Sub
How to use index in select statement?
this way:
SELECT * FROM table1 USE INDEX (col1_index,col2_index)
WHERE col1=1 AND col2=2 AND col3=3;
SELECT * FROM table1 IGNORE INDEX (col3_index)
WHERE col1=1 AND col2=2 AND col3=3;
SELECT * FROM t1 USE INDEX (i1) IGNORE INDEX (i2) USE INDEX (i2);
And many more ways check this
Do I need to explicitly specify?
In PHP, by default, objects are passed as reference to a new object.
See this example:
class X {
var $abc = 10;
}
class Y {
var $abc = 20;
function changeValue($obj)
{
$obj->abc = 30;
}
}
$x = new X();
$y = new Y();
echo $x->abc; //outputs 10
$y->changeValue($x);
echo $x->abc; //outputs 30
Now see this:
class X {
var $abc = 10;
}
class Y {
var $abc = 20;
function changeValue($obj)
{
$obj = new Y();
}
}
$x = new X();
$y = new Y();
echo $x->abc; //outputs 10
$y->changeValue($x);
echo $x->abc; //outputs 10 not 20 same as java does.
Now see this:
class X {
var $abc = 10;
}
class Y {
var $abc = 20;
function changeValue(&$obj)
{
$obj = new Y();
}
}
$x = new X();
$y = new Y();
echo $x->abc; //outputs 10
$y->changeValue($x);
echo $x->abc; //outputs 20 not possible in java.
I hope you can understand this.
The following works on Java 7 and up (see here for documentation).
import java.nio.file.Paths;
Paths.get(".").toAbsolutePath().normalize().toString();

For those using EF Core with ASP.NET Core v1.0.0 I had a similar problem and used the following commands to correct it (@DavidSopko's post pointed me in the right direction, but the details are slightly different for EF Core):
Update-Database <Name of last good migration>
Remove-Migration
For example, in my current development the command became
PM> Update-Database CreateInitialDatabase
Done.
PM> Remove-Migration
Done.
PM>
The Remove-Migration will remove the last migration you applied. If you have a more complex scenario with multiple migrations to remove (I only had 2, the initial and the bad one), I suggest you test the steps in a dummy project.
There doesn't currently appear to be a Get-Migrations command in EF Core (v1.0.0) so you must look in your migrations folder and be familiar with what you have done. However, there is a nice help command:
PM> get-help entityframework
Refreshing dastabase in VS2015 SQL Server Object Explorer, all of my data was preserved and the migration that I wanted to revert was gone :)
Initially I tried Remove-Migration by itself and found the error command confusing:
System.InvalidOperationException: The migration '...' has already been applied to the database. Unapply it and try again. If the migration has been applied to other databases, consider reverting its changes using a new migration.
There are already suggestions on improving this wording, but I'd like the error to say something like this:
Run Update-Database (last good migration name) to revert the database schema back to to that state. This command will unapply all migrations that occurred after the migration specified to Update-Database. You may then run Remove-Migration (migration name to remove)
Output from the EF Core help command follows:
PM> get-help entityframework

it could be not the answer for this case, but as I had the same error-message with .to_csv
I tried .toCSV('name.csv')
and the error-message was different ("SparseDataFrame' object has no attribute 'toCSV'
). So the problem was solved by turning dataframe to dense dataframe
df.to_dense().to_csv("submission.csv", index = False, sep=',', encoding='utf-8')
For Windows:
Method 1 (Two keys pressed at a time)
Method 2 (3 keys pressed at a time)
Please note: If you press and hold Ctrl+K for more than two seconds it will start deleting text so try to be quick with it.
I use the above shortcuts, and they work on my Windows system.
Robby provides a great answer, though I can see you still looking for more information. I implemented REST api calls the easy BUT wrong way. It wasn't until watching this Google I/O video that I understood where I went wrong. It's not as simple as putting together an AsyncTask with a HttpUrlConnection get/put call.
In the Fish Shell the length of an array can be found with:
$ set a 1 2 3 4
$ count $a
4
Say that we want to assign a 10px "cellpadding" and a 15px "cellspacing" to our table, in a HTML5-compliant way. I will show here two methods giving really similar outputs.
Two different sets of CSS properties apply to the same HTML markup for the table, but with opposite concepts:
the first one uses the default value for border-collapse
(separate
) and uses border-spacing
to provide the cellspacing,
the second one switches border-collapse
to collapse
and uses the border
property as the cellspacing.
In both cases, the cellpadding is achieved by assigning padding:10px
to the td
s and, in both cases, the background-color
assigned to them is only for the sake of a clearer demo.
First method:
table{border-spacing:15px}
td{background-color:#00eb55;padding:10px;border:0}
_x000D_
<table>
<tr>
<td>Header 1</td><td>Header 2</td>
</tr>
<tr>
<td>1</td><td>2</td>
</tr>
<tr>
<td>3</td><td>4</td>
</tr>
</table>
_x000D_
Second method:
table{border-collapse:collapse}
td{background-color:#00eb55;padding:10px;border:15px solid #fff}
_x000D_
<table>
<tr>
<td>Header 1</td><td>Header 2</td>
</tr>
<tr>
<td>1</td><td>2</td>
</tr>
<tr>
<td>3</td><td>4</td>
</tr>
</table>
_x000D_
Working my way through Fluent Python (Ramalho) - highly recommended. List comprehension one-ish-liners inspired by Chapter 2:
onlyascii = ''.join([s for s in data if ord(s) < 127])
onlymatch = ''.join([s for s in data if s in
'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'])
Make sure the scp command is available on both sides - both on the client and on the server.
BOTH Server and Client, otherwise you will encounter this kind of (weird)error message on your client: scp: command not found
or something similar even though though you have it all configured locally.
The plugin that @DarinDimitrov posted, jquery-mousewheel
, is broken with jQuery 3+. It would be more advisable to use jquery-wheel
which works with jQuery 3+.
If you don't want to go the jQuery route, MDN highly cautions using the mousewheel
event as it's nonstandard and unsupported in many places. It instead says that you should use the wheel
event as you get much more specificity over exactly what the values you're getting mean. It's supported by most major browsers.
Take a look on pprint, The pprint module provides a capability to “pretty-print” arbitrary Python data structures in a form which can be used as input to the interpreter. If the formatted structures include objects which are not fundamental Python types, the representation may not be loadable. This may be the case if objects such as files, sockets or classes are included, as well as many other objects which are not representable as Python literals.
>>> import pprint
>>> stuff = ['spam', 'eggs', 'lumberjack', 'knights', 'ni']
>>> stuff.insert(0, stuff[:])
>>> pp = pprint.PrettyPrinter(indent=4)
>>> pp.pprint(stuff)
[ ['spam', 'eggs', 'lumberjack', 'knights', 'ni'],
'spam',
'eggs',
'lumberjack',
'knights',
'ni']
>>> pp = pprint.PrettyPrinter(width=41, compact=True)
>>> pp.pprint(stuff)
[['spam', 'eggs', 'lumberjack',
'knights', 'ni'],
'spam', 'eggs', 'lumberjack', 'knights',
'ni']
>>> tup = ('spam', ('eggs', ('lumberjack', ('knights', ('ni', ('dead',
... ('parrot', ('fresh fruit',))))))))
>>> pp = pprint.PrettyPrinter(depth=6)
>>> pp.pprint(tup)
('spam', ('eggs', ('lumberjack', ('knights', ('ni', ('dead', (...)))))))
You can also put the item with the default value selected out of the ng-repeat like follow :
<div ng-app="app" ng-controller="myCtrl">
<select class="form-control" ng-change="unitChanged()" ng-model="data.unit">
<option value="yourDefaultValue">Default one</option>
<option ng-selected="data.unit == item.id" ng-repeat="item in units" ng-value="item.id">{{item.label}}</option>
</select>
</div>
and don't forget the value atribute if you leave it blank you will have the same issue.
On Windows with the ActiveState distribution of Perl, use the ppm command.
Here is a sample for ISO-8859-9;
protected void btnKaydet_Click(object sender, EventArgs e)
{
Response.Clear();
Response.Buffer = true;
Response.ContentType = "application/vnd.openxmlformatsofficedocument.wordprocessingml.documet";
Response.AddHeader("Content-Disposition", "attachment; filename=XXXX.doc");
Response.ContentEncoding = Encoding.GetEncoding("ISO-8859-9");
Response.Charset = "ISO-8859-9";
EnableViewState = false;
StringWriter writer = new StringWriter();
HtmlTextWriter html = new HtmlTextWriter(writer);
form1.RenderControl(html);
byte[] bytesInStream = Encoding.GetEncoding("iso-8859-9").GetBytes(writer.ToString());
MemoryStream memoryStream = new MemoryStream(bytesInStream);
string msgBody = "";
string Email = "[email protected]";
SmtpClient client = new SmtpClient("mail.xxxxx.org");
MailMessage message = new MailMessage(Email, "[email protected]", "ONLINE APP FORM WITH WORD DOC", msgBody);
Attachment att = new Attachment(memoryStream, "XXXX.doc", "application/vnd.openxmlformatsofficedocument.wordprocessingml.documet");
message.Attachments.Add(att);
message.BodyEncoding = System.Text.Encoding.UTF8;
message.IsBodyHtml = true;
client.Send(message);}
Take a look at this page for general Boostrap layout information http://getbootstrap.com/css/#grid-offsetting
Try this:
<div class="col-xs-2" id="p1">One</div>
<div class="col-xs-3">
<div class="col-xs-8 col-xs-offset-2" id="p2">Two</div>
</div>
<div class="col-xs-2" id="p3">Three</div>
<div class="col-xs-3">
<div class="col-xs-8 col-xs-offset-2" id="p4">Four</div>
</div>
<div class="col-xs-2" id="p5">Five</div>
I've split the width into 5 uneven div
with col-xs- 2,3,2,3,2
respectively. The two div
with col-xs-3
are 1.5x the size of the col-xs-2 div
, so the column width needs to be 2/3x (1.5 x 2/3 = 1
) the col-xs-3
widths to match the rest.
This worked for me in Swift 5.0. Set the Storyboard Id in the identity inspector as "destinationVC".
@IBAction func buttonTapped(_ sender: Any) {
let storyboard: UIStoryboard = UIStoryboard(name: "Main", bundle: Bundle.main)
let destVC = storyboard.instantiateViewController(withIdentifier: "destinationVC") as! MyViewController
destVC.modalPresentationStyle = UIModalPresentationStyle.overCurrentContext
destVC.modalTransitionStyle = UIModalTransitionStyle.crossDissolve
self.present(destVC, animated: true, completion: nil)
}
A few solutions to choose from:
json_pp: command utility available in Linux systems for JSON decoding/encoding
echo '{"type":"Bar","id":"1","title":"Foo"}' | json_pp -json_opt pretty,canonical
{
"id" : "1",
"title" : "Foo",
"type" : "Bar"
}
You may want to keep the -json_opt pretty,canonical
argument for predictable ordering.
jq: lightweight and flexible command-line JSON processor. It is written in portable C, and it has zero runtime dependencies.
echo '{"type":"Bar","id":"1","title":"Foo"}' | jq '.'
{
"type": "Bar",
"id": "1",
"title": "Foo"
}
The simplest jq
program is the expression .
, which takes the input and produces it unchanged as output.
For additinal jq
options check the manual
with python:
echo '{"type":"Bar","id":"1","title":"Foo"}' | python -m json.tool
{
"id": "1",
"title": "Foo",

all of the above are correct. Please be sure before that this is a number in a string by doing "typeot x === 'number'" other wise it will return NaN
var num = "fsdfsdf242342";
typeof num => 'string';
var num1 = "12423";
typeof num1 => 'number';
+num1 = > 12423`
You don't want to stretch the span in height?
You have the possiblity to affect one or more flex-items to don't stretch the full height of the container.
To affect all flex-items of the container, choose this:
You have to set align-items: flex-start;
to div
and all flex-items of this container get the height of their content.
div {_x000D_
align-items: flex-start;_x000D_
background: tan;_x000D_
display: flex;_x000D_
height: 200px;_x000D_
}_x000D_
span {_x000D_
background: red;_x000D_
}
_x000D_
<div>_x000D_
<span>This is some text.</span>_x000D_
</div>
_x000D_
To affect only a single flex-item, choose this:
If you want to unstretch a single flex-item on the container, you have to set align-self: flex-start;
to this flex-item. All other flex-items of the container aren't affected.
div {_x000D_
display: flex;_x000D_
height: 200px;_x000D_
background: tan;_x000D_
}_x000D_
span.only {_x000D_
background: red;_x000D_
align-self:flex-start;_x000D_
}_x000D_
span {_x000D_
background:green;_x000D_
}
_x000D_
<div>_x000D_
<span class="only">This is some text.</span>_x000D_
<span>This is more text.</span>_x000D_
</div>
_x000D_
Why is this happening to the span
?
The default value of the property align-items
is stretch
. This is the reason why the span
fill the height of the div
.
Difference between baseline
and flex-start
?
If you have some text on the flex-items, with different font-sizes, you can use the baseline of the first line to place the flex-item vertically. A flex-item with a smaller font-size have some space between the container and itself at top. With flex-start
the flex-item will be set to the top of the container (without space).
div {_x000D_
align-items: baseline;_x000D_
background: tan;_x000D_
display: flex;_x000D_
height: 200px;_x000D_
}_x000D_
span {_x000D_
background: red;_x000D_
}_x000D_
span.fontsize {_x000D_
font-size:2em;_x000D_
}
_x000D_
<div>_x000D_
<span class="fontsize">This is some text.</span>_x000D_
<span>This is more text.</span>_x000D_
</div>
_x000D_
You can find more information about the difference between
baseline
andflex-start
here:
What's the difference between flex-start and baseline?
Something like this:
$.getJSON("http://mywebsite.com/json/get.php?cid=15",
function(data){
$.each(data.products, function(i,product){
content = '<p>' + product.product_title + '</p>';
content += '<p>' + product.product_short_description + '</p>';
content += '<img src="' + product.product_thumbnail_src + '"/>';
content += '<br/>';
$(content).appendTo("#product_list");
});
});
Would take a json object made from a PHP array returned with the key of products. e.g:
Array('products' => Array(0 => Array('product_title' => 'Product 1',
'product_short_description' => 'Product 1 is a useful product',
'product_thumbnail_src' => '/images/15/1.jpg'
)
1 => Array('product_title' => 'Product 2',
'product_short_description' => 'Product 2 is a not so useful product',
'product_thumbnail_src' => '/images/15/2.jpg'
)
)
)
To reload the list you would simply do:
$("#product_list").empty();
And then call getJSON again with new parameters.
I think you can also call Refresh()
.
The hyphen is usually a normal character in regular expressions. Only if it’s in a character class and between two other characters does it take a special meaning.
Thus:
[-]
matches a hyphen.[abc-]
matches a
, b
, c
or a hyphen.[-abc]
matches a
, b
, c
or a hyphen.[ab-d]
matches a
, b
, c
or d
(only here the hyphen denotes a character range).Since your desired output is sorted, you also need to sort it:
>>> j=[4, 5, 6, 7, 1, 3, 7, 5]
>>> sorted(x for x in j if x >= 5)
[5, 5, 6, 7, 7]
They are extension methods. Welcome to a whole new fluent world. :)
If you try to decrypt PKCS5-padded data with the wrong key, and then unpad it (which is done by the Cipher class automatically), you most likely will get the BadPaddingException (with probably of slightly less than 255/256, around 99.61%), because the padding has a special structure which is validated during unpad and very few keys would produce a valid padding.
So, if you get this exception, catch it and treat it as "wrong key".
This also can happen when you provide a wrong password, which then is used to get the key from a keystore, or which is converted into a key using a key generation function.
Of course, bad padding can also happen if your data is corrupted in transport.
That said, there are some security remarks about your scheme:
For password-based encryption, you should use a SecretKeyFactory and PBEKeySpec instead of using a SecureRandom with KeyGenerator. The reason is that the SecureRandom could be a different algorithm on each Java implementation, giving you a different key. The SecretKeyFactory does the key derivation in a defined manner (and a manner which is deemed secure, if you select the right algorithm).
Don't use ECB-mode. It encrypts each block independently, which means that identical plain text blocks also give always identical ciphertext blocks.
Preferably use a secure mode of operation, like CBC (Cipher block chaining) or CTR (Counter). Alternatively, use a mode which also includes authentication, like GCM (Galois-Counter mode) or CCM (Counter with CBC-MAC), see next point.
You normally don't want only confidentiality, but also authentication, which makes sure the message is not tampered with. (This also prevents chosen-ciphertext attacks on your cipher, i.e. helps for confidentiality.) So, add a MAC (message authentication code) to your message, or use a cipher mode which includes authentication (see previous point).
DES has an effective key size of only 56 bits. This key space is quite small, it can be brute-forced in some hours by a dedicated attacker. If you generate your key by a password, this will get even faster. Also, DES has a block size of only 64 bits, which adds some more weaknesses in chaining modes. Use a modern algorithm like AES instead, which has a block size of 128 bits, and a key size of 128 bits (for the standard variant).
Finally, the wait is over with SQL Server 2016. They have introduced the Split string function, STRING_SPLIT
:
select OtherID, cs.Value --SplitData
from yourtable
cross apply STRING_SPLIT (Data, ',') cs
All the other methods to split string like XML, Tally table, while loop, etc.. have been blown away by this STRING_SPLIT
function.
Here is an excellent article with performance comparison: Performance Surprises and Assumptions: STRING_SPLIT.
For older versions, using tally table here is one split string function(best possible approach)
CREATE FUNCTION [dbo].[DelimitedSplit8K]

If you restructured your date format into YYYY/MM/DD then you can use this simple string ordering to achieve the formating you need.
Alternatively, using the SUBSTR(store_name,start,length) command you should be able to restructure the sorting term into the above format
perhaps using the following
SELECT *
FROM vw_view
ORDER BY SUBSTR(EventDate,6,4) + SUBSTR(EventDate, 0, 5) DESC
Authentication is done via a simple ldap_bind command that takes the users DN and the password. The user is authenticated when the bind is successfull. Usually you would get the users DN via an ldap_search based on the users uid or email-address.
Getting the users roles is something different as it is an ldap_search and depends on where and how the roles are stored in the ldap. But you might be able to retrieve the roles during the lap_search used to find the users DN.
My favourite is to extend jQuery with this tiny convenience:
$.fn.exists = function () {
return this.length !== 0;
}
Used like:
$("#notAnElement").exists();
More explicit than using length.
Use RC addressing. So, if I want the background color of Col B to depend upon the value in Col C and apply that from Rows 2 though 20:
Steps:
Select R2C2 to R20C2
Click on Conditional Formatting
Select "Use a formula to determine what cells to format"
Type in the formula: =RC[1] > 25
Create the formatting you want (i.e. background color "yellow")
Applies to: Make sure it says: =R2C2:R20C2
** Note that the "magic" takes place in step 4 ... using RC addressing to look at the value one column to the right of the cell being formatted. In this example, I am checking to see if the value of the cell one column to the right of the cell being formatting contains a value greater than 25 (note that you can put pretty much any formula here that returns a T/F value)
MultipartFile.transferTo(File) is nice, but don't forget to clean the temp file after all.
// ask JVM to ask operating system to create temp file
File tempFile = File.createTempFile(TEMP_FILE_PREFIX, TEMP_FILE_POSTFIX);
// ask JVM to delete it upon JVM exit if you forgot / can't delete due exception
tempFile.deleteOnExit();
// transfer MultipartFile to File
multipartFile.transferTo(tempFile);
// do business logic here
result = businessLogic(tempFile);
// tidy up
tempFile.delete();
Check out Razzlero's comment about File.deleteOnExit() executed upon JVM exit (which may be extremely rare) details below.
Welcome to the fickle world of SQL Server log management.
SOMETHING is wrong, though I don't think anyone will be able to tell you more than that without some additional information. For example, has this database ever been used for Transactional SQL Server replication? This can cause issues like this if a transaction hasn't been replicated to a subscriber.
In the interim, this should at least allow you to kill the log file:
You should now be able to shrink the files (if performing the backup didn't do that for you).
Good luck!
The 1st one is default, when there is nothing special to return or write. 2nd and 3rd are basically the same where 3rd is a bit more expanded version of 2nd
Have a look at
https://developer.mozilla.org/En/Core_JavaScript_1.5_Reference/Global_Objects/Array
for documentation on JavaScript Arrays.
jQuery is a library which adds some magic to JavaScript which is a capable and featurefull scripting language. The libraries just fill in the gaps - get to know the core!
You may be able to adapt a version of the C++ virtual constructor idiom. As far as I know, C# doesn't support covariant return types. I believe that's on many peoples' wish lists.
Installing git and running npm install from git-bash worked for me. Make sure you are in the correct directory.
I wanted to achieve the same goal as you, so I wrote the following method which does exactly that if you pass it an ImageView and a list of references to image drawables.
ImageView demoImage = (ImageView) findViewById(R.id.DemoImage);
int imagesToShow[] = { R.drawable.image1, R.drawable.image2,R.drawable.image3 };
animate(demoImage, imagesToShow, 0,false);
private void animate(final ImageView imageView, final int images[], final int imageIndex, final boolean forever) {
//imageView <-- The View which displays the images
//images[] <-- Holds R references to the images to display
//imageIndex <-- index of the first image to show in images[]
//forever <-- If equals true then after the last image it starts all over again with the first image resulting in an infinite loop. You have been warned.
int fadeInDuration = 500; // Configure time values here
int timeBetween = 3000;
int fadeOutDuration = 1000;
imageView.setVisibility(View.INVISIBLE); //Visible or invisible by default - this will apply when the animation ends
imageView.setImageResource(images[imageIndex]);
Animation fadeIn = new AlphaAnimation(0, 1);
fadeIn.setInterpolator(new DecelerateInterpolator()); // add this
fadeIn.setDuration(fadeInDuration);
Animation fadeOut = new AlphaAnimation(1, 0);
fadeOut.setInterpolator(new AccelerateInterpolator()); // and this
fadeOut.setStartOffset(fadeInDuration + timeBetween);
fadeOut.setDuration(fadeOutDuration);
AnimationSet animation = new AnimationSet(false); // change to false
animation.addAnimation(fadeIn);
animation.addAnimation(fadeOut);
animation.setRepeatCount(1);
imageView.setAnimation(animation);
animation.setAnimationListener(new AnimationListener() {
public void onAnimationEnd(Animation animation) {
if (images.length - 1 > imageIndex) {
animate(imageView, images, imageIndex + 1,forever); //Calls itself until it gets to the end of the array
}
else {
if (forever){
animate(imageView, images, 0,forever); //Calls itself to start the animation all over again in a loop if forever = true
}
}
}
public void onAnimationRepeat(Animation animation) {
// TODO Auto-generated method stub
}
public void onAnimationStart(Animation animation) {
// TODO Auto-generated method stub
}
});
}
Use:
echo %time% & dir & echo %time%
This is, from memory, equivalent to the semi-colon separator in bash
and other UNIXy shells.
There's also &&
(or ||
) which only executes the second command if the first succeeded (or failed), but the single ampersand &
is what you're looking for here.
That's likely to give you the same time however since environment variables tend to be evaluated on read rather than execute.
You can get round this by turning on delayed expansion:
pax> cmd /v:on /c "echo !time! & ping 127.0.0.1 >nul: & echo !time!"
15:23:36.77
15:23:39.85
That's needed from the command line. If you're doing this inside a script, you can just use setlocal
:
@setlocal enableextensions enabledelayedexpansion
@echo off
echo !time! & ping 127.0.0.1 >nul: & echo !time!
endlocal
Just use substring: "apple".substring(3);
will return le
in sql... we use it for "not equals"... I am guessing, its the same in VB aswell.
I really love var_export(). If you like copy/paste-able code, try:
echo '<pre>' . var_export($data, true) . '</pre>';
Or even something like this for color syntax highlighting:
highlight_string("<?php\n\$data =\n" . var_export($data, true) . ";\n?>");
Sometime we might don't want to apply ordering on our result set to add serial number. But if we are going to use ROW_NUMBER()
then we have to have a ORDER BY
clause. So, for that we can simply apply a tricks to avoid any ordering on the result set.
SELECT ROW_NUMBER() OVER(ORDER BY (SELECT 1)) AS ItemNo, ItemName FROM ItemMastetr
For that we don't need to apply order by on our result set. We'll just add ItemNo
on our given result set.
Unless you are already using CollectionUtils I would go for List.isEmpty()
, less dependencies.
Performance wise CollectionUtils will be a tad slower. Because it basically follows the same logic but has additional overhead.
So it would be readability vs. performance vs. dependencies. Not much of a big difference though.
