You've Ruby 1.8 so you need to upgrade to at least 1.9 to make it working.
If so, then check How to install a specific version of a ruby gem?
If this won't help, then reinstalling ruby-dev
again.
Type :set number
(for numbered lines).
Your ProfileDto
class is not referenced in SearchResultDto
. Try adding @XmlSeeAlso(ProfileDto.class)
to SearchResultDto
.
This will surely work:
UPDATE table1
SET table1.price=(SELECT table2.price
FROM table2
WHERE table2.id=table1.id AND table2.item=table1.item);
Yeah, as others have suggested, this error seems to mean that ssh-agent is installed but its service (on windows) hasn't been started.
You can check this by running in Windows PowerShell:
> Get-Service ssh-agent
And then check the output of status is not running.
Status Name DisplayName
------ ---- -----------
Stopped ssh-agent OpenSSH Authentication Agent
Then check that the service has been disabled by running
> Get-Service ssh-agent | Select StartType
StartType
---------
Disabled
I suggest setting the service to start manually. This means that as soon as you run ssh-agent, it'll start the service. You can do this through the Services GUI or you can run the command in admin mode:
> Get-Service -Name ssh-agent | Set-Service -StartupType Manual
Alternatively, you can set it through the GUI if you prefer.
You are trying to link objects compiled by different versions of the compiler. That's not supported in modern versions of VS, at least not if you are using the C++ standard library. Different versions of the standard library are binary incompatible and so you need all the inputs to the linker to be compiled with the same version. Make sure you re-compile all the objects that are to be linked.
The compiler error names the objects involved so the information the the question already has the answer you are looking for. Specifically it seems that the static library that you are linking needs to be re-compiled.
So the solution is to recompile Projectname1.lib with VS2012.
I would use a two file setup like this:
index.php
<?php
session_start();
define('DS', TRUE); // used to protect includes
define('USERNAME', $_SESSION['username']);
define('SELF', $_SERVER['PHP_SELF'] );
if (!USERNAME or isset($_GET['logout']))
include('login.php');
// everything below will show after correct login
?>
login.php
<?php defined('DS') OR die('No direct access allowed.');
$users = array(
"user" => "userpass"
);
if(isset($_GET['logout'])) {
$_SESSION['username'] = '';
header('Location: ' . $_SERVER['PHP_SELF']);
}
if(isset($_POST['username'])) {
if($users[$_POST['username']] !== NULL && $users[$_POST['username']] == $_POST['password']) {
$_SESSION['username'] = $_POST['username'];
header('Location: ' . $_SERVER['PHP_SELF']);
}else {
//invalid login
echo "<p>error logging in</p>";
}
}
echo '<form method="post" action="'.SELF.'">
<h2>Login</h2>
<p><label for="username">Username</label> <input type="text" id="username" name="username" value="" /></p>
<p><label for="password">Password</label> <input type="password" id="password" name="password" value="" /></p>
<p><input type="submit" name="submit" value="Login" class="button"/></p>
</form>';
exit;
?>
No need for array. Just use something like this:
Sub ARRAYER()
Dim Rng As Range
Dim Number_of_Sims As Long
Dim i As Long
Number_of_Sims = 10
Set Rng = Range("C4:G4")
For i = 1 To Number_of_Sims
Rng.Offset(i, 0).Value = Rng.Value
Worksheets("Sheetname").Calculate 'replacing Sheetname with name of your sheet
Next
End Sub
Assuming you have a JSON hash hanging around somewhere, to automatically convert it into something like WarHog's version, wrap your JSON hash contents in %q{hsh}
tags.
This seems to automatically add all the necessary escaped text like in WarHog's answer.
In Mvc You can do it by opening Web.config file it comes under bottom of your project file
Also you can use ui-sref-active directive:
<ul>
<li ui-sref-active="active" class="item">
<a href ui-sref="app.user({user: 'bilbobaggins'})">@bilbobaggins</a>
</li>
<!-- ... -->
</ul>
Or filters:
"stateName" | isState
& "stateName" | includedByState
in case if your table has tbody
let tbl = document.getElementById("tbl").getElementsByTagName('tbody')[0];
console.log(tbl.rows[0].cells[0].innerHTML)
{ }
-->
defines scope, so if(a==1) { int b = 10; }
says, you are defining int b, for {}- this scope. For
if(a==1)
int b =10;
there is no scope. And you will not be able to use b
anywhere.
Very close! In your select
expression, you have to use a pipe (|
) before contains
.
This filter produces the expected output.
. - map(select(.Names[] | contains ("data"))) | .[] .Id
The jq Cookbook has an example of the syntax.
Filter objects based on the contents of a key
E.g., I only want objects whose genre key contains "house".
$ json='[{"genre":"deep house"}, {"genre": "progressive house"}, {"genre": "dubstep"}]' $ echo "$json" | jq -c '.[] | select(.genre | contains("house"))' {"genre":"deep house"} {"genre":"progressive house"}
Colin D asks how to preserve the JSON structure of the array, so that the final output is a single JSON array rather than a stream of JSON objects.
The simplest way is to wrap the whole expression in an array constructor:
$ echo "$json" | jq -c '[ .[] | select( .genre | contains("house")) ]'
[{"genre":"deep house"},{"genre":"progressive house"}]
You can also use the map function:
$ echo "$json" | jq -c 'map(select(.genre | contains("house")))'
[{"genre":"deep house"},{"genre":"progressive house"}]
map unpacks the input array, applies the filter to every element, and creates a new array. In other words, map(f)
is equivalent to [.[]|f]
.
The functions with an s
take string parameters. The others take file
streams.
Depends on the RDBMS or even the JDBC driver.
Most of the times you can use java.sql.Timestamp most of the times along with a prepared statement:
pstmt.setTimestamp( index, new Timestamp( yourJavaUtilDateInstance.getTime() );

If one wants to follow a more Reactive oriented style of programming, then definitely the concept of "Everything is a stream" comes into picture and hence, use Observables to deal with these streams as often as possible.
You need to decide whether the array elements will be stored in row order or column order and then be consistent about it. http://en.wikipedia.org/wiki/Row-major_order
The C language uses row order for Multidimensional arrays
To simulate this with a single dimensional array, you multiply the row index by the width, and add the column index thus:
int array[width * height];
int SetElement(int row, int col, int value)
{
array[width * row + col] = value;
}
type log.txt
But that will give you the whole file. You could change it to:
echo %date%, %time% >> log.txt
echo %date%, %time% > log_last.txt
...
type log_last.txt
to get only the last one.
Matlab allows you to return multiple values as well as receive them inline.
When you call it, receive individual variables inline:
[array, listp, freep] = initialize(size)
When you want to show an URL of remote branches, try:
git remote -v
To call ruby file use : ruby your_program.rb
To execute your ruby file as script:
start your program with #!/usr/bin/env ruby
run that script using ./your_program.rb param
This thread seems to be quite old. If anyone's still looking, the steps mentioned here : https://github.com/burnash/gspread work very well.
import gspread
from oauth2client.service_account import ServiceAccountCredentials
import os
os.chdir(r'your_path')
scope = ['https://spreadsheets.google.com/feeds',
'https://www.googleapis.com/auth/drive']
creds = ServiceAccountCredentials.from_json_keyfile_name('client_secret.json', scope)
gc = gspread.authorize(creds)
wks = gc.open("Trial_Sheet").sheet1
wks.update_acell('H3', "I'm here!")
Make sure to drop your credentials json file in your current directory. Rename it as client_secret.json.
You might run into errors if you don't enable Google Sheet API with your current credentials.
I ended up using the httpclient-4.3.6:
import org.apache.http.client.utils.URIBuilder;
public static void main (String [] args) {
URIBuilder uri = new URIBuilder();
uri.setScheme("http")
.setHost("www.example.com")
.setPath("/somepage.php")
.setParameter("username", "Hello Günter")
.setParameter("p1", "parameter 1");
System.out.println(uri.toString());
}
Output will be:
http://www.example.com/somepage.php?username=Hello+G%C3%BCnter&p1=paramter+1
Mark F's solution is awesome but it's not supported by old browsers. Kennebec's solution is awesome and supported by old browsers but doesn't support regex.
So, if you're looking for a solution that splits your string only once, that is supported by old browsers and supports regex, here's my solution:
String.prototype.splitOnce = function(regex)_x000D_
{_x000D_
var match = this.match(regex);_x000D_
if(match)_x000D_
{_x000D_
var match_i = this.indexOf(match[0]);_x000D_
_x000D_
return [this.substring(0, match_i),_x000D_
this.substring(match_i + match[0].length)];_x000D_
}_x000D_
else_x000D_
{ return [this, ""]; }_x000D_
}_x000D_
_x000D_
var str = "something/////another thing///again";_x000D_
_x000D_
alert(str.splitOnce(/\/+/)[1]);

If some one working on monorepo following react-native-web-monorepo than you need to config-overrides.js

I know Mickey S. solved his issue with Java 8, but Pavel S. was on to something. If you're working locally with an applet, setting your Intranet Zone to Low security and then setting Java security in Control Panel -> Java -> Security setting to Medium from High does solve the problem of running local applets with Java 7u51 (and u55) on Win 7 with IE 11.
(Specifically, I have a little test tool for barcode generation from IDAutomation that is crafted as an applet which wouldn't work on the above config, until I performed the listed steps.)
This is not intended to be "the good answer", as this question ask explicitly for ObjectiveC. As Apple introduced Swift at the WWDC14, I'd like to share the different ways to use block (or closures) in Swift.
You have many ways offered to pass a block equivalent to function in Swift.
I found three.
To understand this I suggest you to test in playground this little piece of code.
func test(function:String -> String) -> String
{
return function("test")
}
func funcStyle(s:String) -> String
{
return "FUNC__" + s + "__FUNC"
}
let resultFunc = test(funcStyle)
let blockStyle:(String) -> String = {s in return "BLOCK__" + s + "__BLOCK"}
let resultBlock = test(blockStyle)
let resultAnon = test({(s:String) -> String in return "ANON_" + s + "__ANON" })
println(resultFunc)
println(resultBlock)
println(resultAnon)
As Swift is optimized for asynchronous development, Apple worked more on closures. The first is that function signature can be inferred so you don't have to rewrite it.
let resultShortAnon = test({return "ANON_" + $0 + "__ANON" })
let resultShortAnon2 = test({myParam in return "ANON_" + myParam + "__ANON" })
This special case works only if the block is the last argument, it's called trailing closure
Here is an example (merged with inferred signature to show Swift power)
let resultTrailingClosure = test { return "TRAILCLOS_" + $0 + "__TRAILCLOS" }
Finally:
Using all this power what I'd do is mixing trailing closure and type inference (with naming for readability)
PFFacebookUtils.logInWithPermissions(permissions) {
user, error in
if (!user) {
println("Uh oh. The user cancelled the Facebook login.")
} else if (user.isNew) {
println("User signed up and logged in through Facebook!")
} else {
println("User logged in through Facebook!")
}
}
You can send email natively from within SQL Server using Database Mail. This is a great tool for notifying sysadmins about errors or other database events. You could also use it to send a report or an email message to an end user. The basic syntax for this is:
EXEC msdb.dbo.sp_send_dbmail
@recipients='[email protected]',
@subject='Testing Email from SQL Server',
@body='<p>It Worked!</p><p>Email sent successfully</p>',
@body_format='HTML',
@from_address='Sender Name <[email protected]>',
@reply_to='[email protected]'
Before use, Database Mail must be enabled using the Database Mail Configuration Wizard, or sp_configure. A database or Exchange admin might need to help you configure this. See http://msdn.microsoft.com/en-us/library/ms190307.aspx and http://www.codeproject.com/Articles/485124/Configuring-Database-Mail-in-SQL-Server for more information.
With a regular expression and the function gsub()
:
group <- c("12357e", "12575e", "197e18", "e18947")
group
[1] "12357e" "12575e" "197e18" "e18947"
gsub("e", "", group)
[1] "12357" "12575" "19718" "18947"
What gsub
does here is to replace each occurrence of "e"
with an empty string ""
.

Here's the quote on AssemblyInfo.cs from MSDN:
You can specify all the values or you can accept the default build number, revision number, or both by using an asterisk (). For example, [assembly:AssemblyVersion("2.3.25.1")] indicates 2 as the major version, 3 as the minor version, 25 as the build number, and 1 as the revision number. A version number such as [assembly:AssemblyVersion("1.2.")] specifies 1 as the major version, 2 as the minor version, and accepts the default build and revision numbers. A version number such as [assembly:AssemblyVersion("1.2.15.*")] specifies 1 as the major version, 2 as the minor version, 15 as the build number, and accepts the default revision number. The default build number increments daily. The default revision number is random
This effectively says, if you put a 1.1.* into assembly info, only build number will autoincrement, and it will happen not after every build, but daily. Revision number will change every build, but randomly, rather than in an incrementing fashion.
This is probably enough for most use cases. If that's not what you're looking for, you're stuck with having to write a script which will autoincrement version # on pre-build step
FMJ can do this, as can the supporting library it uses, LTI-CIVIL. Both are on sourceforge.
I realize this is an old post but I find myself coming back to this thread a lot as it is one of the top search results when searching for this topic. However, I always leave more confused then when I came due to the conflicting information. Ultimately I always have to perform my own tests to figure it out. So this time I will post my findings.
TL;DR Most people will want to use Exit
to terminate a running scripts. However, if your script is merely declaring functions to later be used in a shell, then you will want to use Return
in the definitions of said functions.
Exit: This will "exit" the currently running context. If you call this command from a script it will exit the script. If you call this command from the shell it will exit the shell.
If a function calls the Exit command it will exit what ever context it is running in. So if that function is only called from within a running script it will exit that script. However, if your script merely declares the function so that it can be used from the current shell and you run that function from the shell, it will exit the shell because the shell is the context in which the function contianing the Exit
command is running.
Note: By default if you right click on a script to run it in PowerShell, once the script is done running, PowerShell will close automatically. This has nothing to do with the Exit
command or anything else in your script. It is just a default PowerShell behavior for scripts being ran using this specific method of running a script. The same is true for batch files and the Command Line window.
Return: This will return to the previous call point. If you call this command from a script (outside any functions) it will return to the shell. If you call this command from the shell it will return to the shell (which is the previous call point for a single command ran from the shell). If you call this command from a function it will return to where ever the function was called from.
Execution of any commands after the call point that it is returned to will continue from that point. If a script is called from the shell and it contains the Return
command outside any functions then when it returns to the shell there are no more commands to run thus making a Return
used in this way essentially the same as Exit
.
Break: This will break out of loops and switch cases. If you call this command while not in a loop or switch case it will break out of the script. If you call Break
inside a loop that is nested inside a loop it will only break out of the loop it was called in.
There is also an interesting feature of Break
where you can prefix a loop with a label and then you can break out of that labeled loop even if the Break
command is called within several nested groups within that labeled loop.
While ($true) {
# Code here will run
:myLabel While ($true) {
# Code here will run
While ($true) {
# Code here will run
While ($true) {
# Code here will run
Break myLabel
# Code here will not run
}
# Code here will not run
}
# Code here will not run
}
# Code here will run
}
I wrote a (recursive) function to delete any row based on its primary key. I wrote this because I did not want to create my constraints as "on delete cascade". I wanted to be able to delete complex sets of data (as a DBA) but not allow my programmers to be able to cascade delete without thinking through all of the repercussions.
I'm still testing out this function, so there may be bugs in it -- but please don't try it if your DB has multi column primary (and thus foreign) keys. Also, the keys all have to be able to be represented in string form, but it could be written in a way that doesn't have that restriction. I use this function VERY SPARINGLY anyway, I value my data too much to enable the cascading constraints on everything.
Basically this function is passed in the schema, table name, and primary value (in string form), and it will start by finding any foreign keys on that table and makes sure data doesn't exist-- if it does, it recursively calls itsself on the found data. It uses an array of data already marked for deletion to prevent infinite loops. Please test it out and let me know how it works for you. Note: It's a little slow.
I call it like so:
select delete_cascade('public','my_table','1');
create or replace function delete_cascade(p_schema varchar, p_table varchar, p_key varchar, p_recursion varchar[] default null)

What I can do to fix this (other than installing a real SSL certificate).
You can't.
On an https webpage you can only make AJAX request to https webpage (With a certificate trusted by the browser, if you use a self-signed one, it will not work for your visitors)
This should also work:
ArrayList<String> orig = new ArrayList<String>();
ArrayList<String> copy = (ArrayList<String>) orig.clone()
The first constructor in the header should not end with a semicolon. #include <string>
is missing in the header. string
is not qualified with std::
in the .cpp file. Those are all simple syntax errors. More importantly: you are not using references, when you should. Also the way you use the ifstream
is broken. I suggest learning C++ before trying to use it.
Let's fix this up:
//polygone.h
# if !defined(__POLYGONE_H__)
# define __POLYGONE_H__
#include <iostream>
#include <string>
class Polygone {
public:
// declarations have to end with a semicolon, definitions do not
Polygone(){} // why would we needs this?
Polygone(const std::string& fichier);
};
# endif
and
//polygone.cc
// no need to include things twice
#include "polygone.h"
#include <fstream>
Polygone::Polygone(const std::string& nom)
{
std::ifstream fichier (nom, ios::in);
if (fichier.is_open())
{
// keep the scope as tiny as possible
std::string line;
// getline returns the stream and streams convert to booleans
while ( std::getline(fichier, line) )
{
std::cout << line << std::endl;
}
}
else
{
std::cerr << "Erreur a l'ouverture du fichier" << std::endl;
}
}
For example, you have a repo like the following:

text.md
subpro/
subtext.md
subsubpro/
subsubtext.md
subsubpro2/
subsubtext2.md
The relative link to subtext.md
in text.md
might look like this:
[this subtext](subpro/subtext.md)
The relative link to subsubtext.md
in text.md
might look like this:

The relative link to subtext.md
in subsubtext.md
might look like this:

The relative link to subsubtext2.md
in subsubtext.md
might look like this:
[this subsubtext2](../subsubpro2/subsubtext2.md)
The relative link to text.md

I had the same issue in a Windows Service. All keys where in the right place in the registry. The build of the service was done for x86 and I still got the exception. I found out about CorFlags.exe
Run this on your service.exe
without flags to verify if you run under 32 bit. If not run it with the flag /32BIT+ /Force
(Force only for signed assemblies)
If you have UAC turned you can get the following error: corflags : error CF001 : Could not open file for writing
Give the user full control on the assemblies.
try this function
function navigate(divId) {
$j('html, body').animate({ scrollTop: $j("#"+divId).offset().top }, 1500);
}
Pass the div id as parameter it will work I am using it already
You can always try doing it manually from the command prompt. Navigate to the path of the file and type:
gcc filename.c -o filename
I stumbled on this question trying to get the organization/repo
string from a git host like github or gitlab.
This is working for me:
git config --get remote.origin.url | sed -e 's/^git@.*:\([[:graph:]]*\).git/\1/'
It uses sed
to replace the output of the git config
command with just the organization and repo name.
Something like github/scientist
would be matched by the character class [[:graph:]]
in the regular expression.
The \1
tells sed to replace everything with just the matched characters.
You can simply write :
class A(object):
def __init__(self):
print "Initialiser A was called"
class B(A):
def __init__(self):
A.__init__(self)
# A.__init__(self,<parameters>) if you want to call with parameters
print "Initialiser B was called"
class C(B):
def __init__(self):
# A.__init__(self) # if you want to call most super class...
B.__init__(self)
print "Initialiser C was called"
Obviously an old post, but this seems to be working for me....
Application.Wait (Now + TimeValue("0:00:01") / 1000)
Divide by whatever you need. A tenth, a hundredth, etc. all seem to work. By removing the "divide by" portion, the macro does take longer to run, so therefore, with no errors present, I have to believe it works.
Dominc has the right idea, but put the calculation on the other side of the expression.
SELECT * FROM my_table WHERE endTime < DATE_SUB(CONVERT_TZ(NOW(), @@global.time_zone, 'GMT'), INTERVAL 30 MINUTE)
This has the advantage that you're doing the 30 minute calculation once instead of on every row. That also means MySQL can use the index on that column. Both of thse give you a speedup.
The DBHelper class is what handles the opening and closing of sqlite databases as well sa creation and updating, and a decent article on how it all works is here. When I started android it was very useful (however I've been objective-c lately, and forgotten most of it to be any use.
I was trying to organize my vue app code, and came across this question , since I have a lot of logic in my component and can not use other sub-coponents , it makes sense to use many functions in a separate js file and call them in the vue file, so here is my attempt
1)The Component (.vue file)
//MyComponent.vue file
<template>
<div>
<div>Hello {{name}}</div>
<button @click="function_A">Read Name</button>
<button @click="function_B">Write Name</button>
<button @click="function_C">Reset</button>
<div>{{message}}</div>
</div>
</template>
<script>
import Mylib from "./Mylib"; // <-- import
export default {
name: "MyComponent",
data() {
return {
name: "Bob",
message: "click on the buttons"
};
},
methods: {
function_A() {
Mylib.myfuncA(this); // <---read data
},
function_B() {
Mylib.myfuncB(this); // <---write data
},
function_C() {
Mylib.myfuncC(this); // <---write data
}
}
};
</script>
2)The External js file
//Mylib.js
let exports = {};
// this (vue instance) is passed as that , so we
// can read and write data from and to it as we please :)
exports.myfuncA = (that) => {
that.message =
"you hit ''myfuncA'' function that is located in Mylib.js and data.name = " +
that.name;
};
exports.myfuncB = (that) => {
that.message =
"you hit ''myfuncB'' function that is located in Mylib.js and now I will change the name to Nassim";
that.name = "Nassim"; // <-- change name to Nassim
};
exports.myfuncC = (that) => {
that.message =
"you hit ''myfuncC'' function that is located in Mylib.js and now I will change the name back to Bob";
that.name = "Bob"; // <-- change name to Bob
};
export default exports;
3)see it in action : https://codesandbox.io/s/distracted-pare-vuw7i?file=/src/components/MyComponent.vue
after getting more experience with Vue , I found out that you could use mixins too to split your code into different files and make it easier to code and maintain see https://vuejs.org/v2/guide/mixins.html
There is no documented LEFT() function in Oracle. Find the full set here.
Probably what you have is a user-defined function. You can check that easily enough by querying the data dictionary:
select * from all_objects
where object_name = 'LEFT'
But there is the question of why the stored procedure works and the query doesn't. One possible solution is that the stored procedure is owned by another schema, which also owns the LEFT() function. They have granted rights on the procedure but not its dependencies. This works because stored procedures run with DEFINER privileges by default, so you run the stored procedure as if you were its owner.
If this is so then the data dictionary query I listed above won't help you: it will only return rows for objects you have rights on. In which case you will need to run the query as the stored procedure's owner or connect as a user with the rights to query DBA_OBJECTS instead.
Some cron implementations support the "L" flag to represent the last day of the month.
If you're lucky to be using one of those implementations, it's as simple as:
0 55 23 L * ?
That will run at 11:55 pm on the last day of every month.

You can try that too, for solve timeout problem:
If you didn't add httpRuntime to your webconfig, add that in <system.web>
tag
<sytem.web>
<httpRuntime maxRequestLength="20000" executionTimeout="999999"/>
</system.web>
and
Modify your connection string like this;
<add name="connstring" connectionString="Data Source=DSourceName;Initial Catalog=DBName;Integrated Security=True;Max Pool Size=50000;Pooling=True;" providerName="System.Data.SqlClient" />
At last use
try
{...}
catch
{...}
finaly
{
connection.close();
}
I would do something like this:
HTML:
<div class="wrapper">
<div class="side">sidebar here</div>
<div class="main">
<textarea class="taclass"></textarea>
</div>
</div><!--/ wrapper -->
CSS:
.wrapper{
display: block;
width: 100%;
overflow: hidden;
}
.side{
float:left;
width:20%;
}
.main{
float:right;
width:80%;
}
.taclass{
display:block;
width:100%;
padding:2%;
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;
}
If possible, you'd be better off handling the load
event within the iframe's document and calling out to a function in the containing document. This has the advantage of working in all browsers and only running once.
In the main document:
function iframeLoaded() {
alert("Iframe loaded!");
}
In the iframe document:
window.onload = function() {
parent.iframeLoaded();
}
This is the simple example to use both of them:
import {
Directive, HostListener, HostBinding
}
from '@angular/core';
@Directive({
selector: '[Highlight]'
})
export class HighlightDirective {
@HostListener('mouseenter') mouseover() {
this.backgroundColor = 'green';
};
@HostListener('mouseleave') mouseleave() {
this.backgroundColor = 'white';
}
@HostBinding('style.backgroundColor') get setColor() {
return this.backgroundColor;
};
private backgroundColor = 'white';
constructor() {}
}
Introduction:
HostListener can bind an event to the element.
HostBinding can bind a style to the element.
this is directive, so we can use it for
Some TextSo according to the debug, we can find that this div has been binded style = "background-color:white"
Some Textwe also can find that EventListener of this div has two event: mouseenter
and mouseleave
. So when we move the mouse into the div, the colour will become green, mouse leave, the colour will become white.
Another method (which it appears no-one has mentioned thus far), is to add an additional KeyValue pair to the element's Style array. i.e
Div.Style.Add("display", "none");
This has the added benefit of merely hiding the element, rather than preventing it from being written to the DOM to begin with - unlike the "Visible" property. i.e.
Div.Visible = false
results in the div never being written to the DOM.
Edit: This should be done in the 'code-behind', I.e. The *.aspx.cs file.
@GianCarlo: You can try calling System property user.dir that will give you root of your java project and then do append this path to your relative path for example:
String root = System.getProperty("user.dir");
String filepath = "/path/to/yourfile.txt"; // in case of Windows: "\\path \\to\\yourfile.txt
String abspath = root+filepath;
// using above path read your file into byte []
File file = new File(abspath);
FileInputStream fis = new FileInputStream(file);
byte []filebytes = new byte[(int)file.length()];
fis.read(filebytes);
A other users suggested,
.empty()
is good enought, because it removes all descendant nodes (both tag-nodes and text-nodes) AND all kind of data stored inside those nodes. See the JQuery's API empty documentation.
If you wish to keep data, like event handlers for example, you should use
.detach()
as described on the JQuery's API detach documentation.
The method .remove() could be usefull for similar purposes.

I had the same error here MacOSX 10.6.8 - it seems ruby checks to see if any directory (including the parents) in the path are world writable. In my case there wasn't a /usr/local/bin present as nothing had created it.
so I had to do
sudo chmod 775 /usr/local
to get rid of the warning.
A question here is does any non root:wheel process in MacOS need to create anything in /usr/local ?
This is a very bothersome question, and I feel contributes to many being opposed to Java despite how useful of a language it is.
The fact that you can't trust "System.gc" to do anything is incredibly daunting and can easily invoke "Fear, Uncertainty, Doubt" feel to the language.
In many cases, it is nice to deal with memory spikes that you cause on purpose before an important event occurs, which would cause users to think your program is badly designed/unresponsive.
Having ability to control the garbage collection would be very a great education tool, in turn improving people's understanding how the garbage collection works and how to make programs exploit it's default behavior as well as controlled behavior.
Let me review the arguments of this thread.
Often, the program may not be doing anything and you know it's not doing anything because of the way it was designed. For instance, it might be doing some kind of long wait with a large wait message box, and at the end it may as well add a call to collect garbage because the time to run it will take a really small fraction of the time of the long wait but will avoid gc from acting up in the middle of a more important operation.
I disagree, it doesn't matter what garbage collector you have. Its' job is to track garbage and clean it.
By calling the gc during times where usage is less critical, you reduce odds of it running when your life relies on the specific code being run but instead it decides to collect garbage.
Sure, it might not behave the way you want or expect, but when you do want to call it, you know nothing is happening, and user is willing to tolerate slowness/downtime. If the System.gc works, great! If it doesn't, at least you tried. There's simply no down side unless the garbage collector has inherent side effects that do something horribly unexpected to how a garbage collector is suppose to behave if invoked manually, and this by itself causes distrust.
It is a use case that cannot be achieved reliably, but could be if the system was designed that way. It's like making a traffic light and making it so that some/all of the traffic lights' buttons don't do anything, it makes you question why the button is there to begin with, javascript doesn't have garbage collection function so we don't scrutinize it as much for it.
what is a "hint"? what is "ignore"? a computer cannot simply take hints or ignore something, there are strict behavior paths it takes that may be dynamic that are guided by the intent of the system. A proper answer would include what the garbage collector is actually doing, at implementation level, that causes it to not perform collection when you request it. Is the feature simply a nop? Is there some kind of conditions that must me met? What are these conditions?
As it stands, Java's GC often seems like a monster that you just don't trust. You don't know when it's going to come or go, you don't know what it's going to do, how it's going to do it. I can imagine some experts having better idea of how their Garbage Collection works on per-instruction basis, but vast majority simply hopes it "just works", and having to trust an opaque-seeming algorithm to do work for you is frustrating.
There is a big gap between reading about something or being taught something, and actually seeing the implementation of it, the differences across systems, and being able to play with it without having to look at the source code. This creates confidence and feeling of mastery/understanding/control.
To summarize, there is an inherent problem with the answers "this feature might not do anything, and I won't go into details how to tell when it does do something and when it doesn't and why it won't or will, often implying that it is simply against the philosophy to try to do it, even if the intent behind it is reasonable".
It might be okay for Java GC to behave the way it does, or it might not, but to understand it, it is difficult to truly follow in which direction to go to get a comprehensive overview of what you can trust the GC to do and not to do, so it's too easy simply distrust the language, because the purpose of a language is to have controlled behavior up to philosophical extent(it's easy for a programmer, especially novices to fall into existential crisis from certain system/language behaviors) you are capable of tolerating(and if you can't, you just won't use the language until you have to), and more things you can't control for no known reason why you can't control them is inherently harmful.

You could use tr
, like this:
tr " " .
Example:

Specify a size for the item and warehouse like in the [dbo].[testing1] FUNCTION
@trackingItems1 TABLE (
item nvarchar(25) NULL, -- 25 OR equal size of your item column
warehouse nvarchar(25) NULL, -- same as above
price int NULL
)
Since in MSSQL only saying only nvarchar is equal to nvarchar(1) hence the values of the column from the stock table are truncated
While Python's default glob doesn't really follow after Bash's glob, you can do this with other libraries. We can enable braces in wcmatch's glob.
>>> from wcmatch import glob
>>> glob.glob('*.{md,ini}', flags=glob.BRACE)
['LICENSE.md', 'README.md', 'tox.ini']
You can even use extended glob patterns if that is your preference:
from wcmatch import glob
>>> glob.glob('*.@(md|ini)', flags=glob.EXTGLOB)
['LICENSE.md', 'README.md', 'tox.ini']
I had a similar issue uploading to an S3 bucket protected with KWS encryption. I have a minimal policy that allows the addition of objects under a specific s3 key.
I needed to add the following KMS permissions to my policy to allow the role to put objects in the bucket. (Might be slightly more than are strictly required)

There are two things I think you could try to develop iPhone applications.
You can try the Aptana mobile wep app plugin for eclipse which is nice, although still in early stage. It comes with a emulator for running the applications so this could be helpful
You can try cocoa

Sounds like you don't want to resolve dns yourself (this might be the wrong nomenclature) dnspython appears to be a standalone dns client that will understandably ignore your operating system because its bypassing the operating system's utillities.
We can look at a shell utility named getent
to understand how the (debian 11 alike) operating system resolves dns for programs, this is likely the standard for all *nix like systems that use a socket implementation.
see man getent
's "hosts" section, which mentions the use of getaddrinfo
, which we can see as man getaddrinfo
and to use it in python, we have to extract some info from the data structures
.
import socket
def get_ipv4_by_hostname(hostname):
# see `man getent` `/ hosts `
# see `man getaddrinfo`
return list(
i # raw socket structure
[4] # internet protocol info
[0] # address
for i in
socket.getaddrinfo(
hostname,
0 # port, required
)
if i[0] is socket.AddressFamily.AF_INET # ipv4
# ignore duplicate addresses with other socket types
and i[1] is socket.SocketKind.SOCK_RAW
)
print(get_ipv4_by_hostname('localhost'))
print(get_ipv4_by_hostname('google.com'))
The read_sql
docs say this params
argument can be a list, tuple or dict (see docs).
To pass the values in the sql query, there are different syntaxes possible: ?
, :1
, :name
, %s
, %(name)s
(see PEP249).
But not all of these possibilities are supported by all database drivers, which syntax is supported depends on the driver you are using (psycopg2
in your case I suppose).
In your second case, when using a dict, you are using 'named arguments', and according to the psycopg2
documentation, they support the %(name)s
style (and so not the :name
I suppose), see http://initd.org/psycopg/docs/usage.html#query-parameters.
So using that style should work:
df = psql.read_sql(('select "Timestamp","Value" from "MyTable" '
'where "Timestamp" BETWEEN %(dstart)s AND %(dfinish)s'),
db,params={"dstart":datetime(2014,6,24,16,0),"dfinish":datetime(2014,6,24,17,0)},
index_col=['Timestamp'])
For anyone still looking to do this in 2020. So long as you are purely using it for development purposes you can download a full featured version of SQL Server directly from Microsoft at https://www.microsoft.com/en-us/sql-server/sql-server-downloads.
Update to Swift 3
let image = UIImage(named: "name")

button.addTarget(self, action: #selector(self.btnAbsRetClicked(_:)), for:.touchUpInside)

Well if you are new to C# with cmd-line exp. you can use online sites like "https://curl.olsh.me/" or search curl to C# converter will returns site that could do that for you.
or if you are using postman you can use Generate Code Snippet only problem with Postman code generator is the dependency on RestSharp library.
I dont know if this useful for you when you resize your page:
$(window).resize(function() {
if(screen.width == window.innerWidth){
alert("you are on normal page with 100% zoom");
} else if(screen.width > window.innerWidth){
alert("you have zoomed in the page i.e more than 100%");
} else {
alert("you have zoomed out i.e less than 100%");
}
});
You can copy the contents of the export_graphviz file and you can paste the same in the webgraphviz.com site.
You can check out the article on How to visualize the decision tree in Python with graphviz for more information.
Use replace
method of strings not strip
:
s = s.replace(',','')
An example:
>>> s = 'Foo, bar'
>>> s.replace(',',' ')
'Foo bar'
>>> s.replace(',','')
'Foo bar'
>>> s.strip(',') # clears the ','s at the start and end of the string which there are none
'Foo, bar'
>>> s.strip(',') == s
True
class Test extends Thread
{
public void run(){
try{
Thread.sleep(10000);
}catch(InterruptedException e){
System.out.println("test1");
throw new RuntimeException("Thread interrupted..."+e);
}
}
public static void main(String args[]){
Test t1=new Test1();
t1.start();
try{
t1.interrupt();
}catch(Exception e){
System.out.println("test2");
System.out.println("Exception handled "+e);
}
}
}
Its output doesn't contain test2 , so its not handling runtime exception. @jon skeet, @Jan Zyka
For my project's setup, "${pageContext.request.contextPath}"= refers to "src/main/webapp". Another way to tell is by right clicking on your project in Eclipse and then going to Properties:
Edit: You should use the json2.js library from Douglas Crockford instead of implementing the code below. It provides some extra features and better/older browser support.
Grab the json2.js file from: https://github.com/douglascrockford/JSON-js
// implement JSON.stringify serialization
JSON.stringify = JSON.stringify || function (obj) {
var t = typeof (obj);
if (t != "object" || obj === null) {
// simple data type
if (t == "string") obj = '"'+obj+'"';
return String(obj);
}
else {
// recurse array or object
var n, v, json = [], arr = (obj && obj.constructor == Array);
for (n in obj) {
v = obj[n]; t = typeof(v);
if (t == "string") v = '"'+v+'"';
else if (t == "object" && v !== null) v = JSON.stringify(v);
json.push((arr ? "" : '"' + n + '":') + String(v));
}
return (arr ? "[" : "{") + String(json) + (arr ? "]" : "}");
}
};
var tmp = {one: 1, two: "2"};
JSON.stringify(tmp); // '{"one":1,"two":"2"}'
Code from: http://www.sitepoint.com/blogs/2009/08/19/javascript-json-serialization/
Eclipse likes lots of RAM. Use at least -Xmx512M. More if available.
You can use the ParallelForEachAsync
extension method from AsyncEnumerator NuGet Package:
using Dasync.Collections;
var bag = new ConcurrentBag<object>();
await myCollection.ParallelForEachAsync(async item =>
{
// some pre stuff
var response = await GetData(item);
bag.Add(response);
// some post stuff
}, maxDegreeOfParallelism: 10);
var count = bag.Count;
Instead of using $http.get('abc/xyz/getSomething') try to use $http.jsonp('abc/xyz/getSomething')
return{
getList:function(){
return $http.jsonp('http://localhost:8080/getNames');
}
}
Using Value2
gives a performance benefit. As per Charles Williams blog
Range.Value2 works the same way as Range.Value, except that it does not check the cell format and convert to Date or Currency. And thats probably why its faster than .Value when retrieving numbers.
So
DirArray = [a1:a5].Value2
To display the item number on the repeater you can use the Container.ItemIndex
property.
<asp:repeater id="rptRepeater" runat="server">
<itemtemplate>
Item <%# Container.ItemIndex + 1 %>| <%# Eval("Column1") %>
</itemtemplate>
<separatortemplate>
<br />
</separatortemplate>
</asp:repeater>
Swift 4.0
Store:
let arrayFruit = ["Apple","Banana","Orange","Grapes","Watermelon"]
//store in user default
UserDefaults.standard.set(arrayFruit, forKey: "arrayFruit")
Fetch:
if let arr = UserDefaults.standard.array(forKey: "arrayFruit") as? [String]{
print(arr)
}
Something like this should do the trick (However, read after the snippet for more info)
CREATE PROCEDURE GetFilteredData()
BEGIN
DECLARE bDone INT;
DECLARE var1 CHAR(16); -- or approriate type
DECLARE Var2 INT;
DECLARE Var3 VARCHAR(50);
DECLARE curs CURSOR FOR SELECT something FROM somewhere WHERE some stuff;
DECLARE CONTINUE HANDLER FOR NOT FOUND SET bDone = 1;
DROP TEMPORARY TABLE IF EXISTS tblResults;
CREATE TEMPORARY TABLE IF NOT EXISTS tblResults (
--Fld1 type,
--Fld2 type,
--...
);
OPEN curs;
SET bDone = 0;
REPEAT
FETCH curs INTO var1,, b;
IF whatever_filtering_desired
-- here for whatever_transformation_may_be_desired
INSERT INTO tblResults VALUES (var1, var2, var3 ...);
END IF;
UNTIL bDone END REPEAT;
CLOSE curs;
SELECT * FROM tblResults;
END
A few things to consider...
Concerning the snippet above:
More generally: trying to avoid needing a cursor.
I purposely named the cursor variable curs[e], because cursors are a mixed blessing. They can help us implement complicated business rules that may be difficult to express in the declarative form of SQL, but it then brings us to use the procedural (imperative) form of SQL, which is a general feature of SQL which is neither very friendly/expressive, programming-wise, and often less efficient performance-wise.
Maybe you can look into expressing the transformation and filtering desired in the context of a "plain" (declarative) SQL query.
The latest JDBC MSSQL connectivity driver can be found on JDBC 4.0
The class file should be in the classpath. If you are using eclipse you can easily do the same by doing the following -->
Right Click Project Name --> Properties --> Java Build Path --> Libraries --> Add External Jars
Also as already been pointed out by @Cheeso the correct way to access is jdbc:sqlserver://server:port;DatabaseName=dbname
Meanwhile please find a sample class for accessing MSSQL DB (2008 in my case).
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;
public class ConnectMSSQLServer
{
public void dbConnect(String db_connect_string,
String db_userid,
String db_password)
{
try {
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
Connection conn = DriverManager.getConnection(db_connect_string,
db_userid, db_password);
System.out.println("connected");
Statement statement = conn.createStatement();
String queryString = "select * from SampleTable";
ResultSet rs = statement.executeQuery(queryString);
while (rs.next()) {
System.out.println(rs.getString(1));
}
conn.close();
} catch (Exception e) {
e.printStackTrace();
}
}
public static void main(String[] args)
{
ConnectMSSQLServer connServer = new ConnectMSSQLServer();
connServer.dbConnect("jdbc:sqlserver://xx.xx.xx.xxxx:1433;databaseName=MyDBName", "DB_USER","DB_PASSWORD");
}
}
Hope this helps.
Set and Get methods are a pattern of data encapsulation. Instead of accessing class member variables directly, you define get
methods to access these variables, and set
methods to modify them. By encapsulating them in this manner, you have control over the public interface, should you need to change the inner workings of the class in the future.
For example, for a member variable:
Integer x;
You might have methods:
Integer getX(){ return x; }
void setX(Integer x){ this.x = x; }
chiccodoro also mentioned an important point. If you only want to allow read access to the field for any foreign classes, you can do that by only providing a public get
method and keeping the set
private or not providing a set
at all.
It seems that you want to use step parameter of range function. From documentation:
range(start, stop[, step]) This is a versatile function to create lists containing arithmetic progressions. It is most often used in for loops. The arguments must be plain integers. If the step argument is omitted, it defaults to 1. If the start argument is omitted, it defaults to 0. The full form returns a list of plain integers [start, start + step, start + 2 * step, ...]. If step is positive, the last element is the largest start + i * step less than stop; if step is negative, the last element is the smallest start + i * step greater than stop. step must not be zero (or else ValueError is raised). Example:
>>> range(10) [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
>>> range(1, 11) [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
>>> range(0, 30, 5) [0, 5, 10, 15, 20, 25]
>>> range(0, 10, 3) [0, 3, 6, 9]
>>> range(0, -10, -1) [0, -1, -2, -3, -4, -5, -6, -7, -8, -9]
>>> range(0) []
>>> range(1, 0) []
In your case to get [0,2,4] you can use:
range(0,6,2)
OR in your case when is a var:
idx = None
for i in range(len(str1)):
if idx and i < idx:
continue
for j in range(len(str2)):
if str1[i+j] != str2[j]:
break
else:
idx = i+j
You can create a directory with PHP using the mkdir() function.
mkdir("/path/to/my/dir", 0700);
You can use fopen() to create a file inside that directory with the use of the mode w
.
fopen('myfile.txt', 'w');
w : Open for writing only; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.
try this : here select is your select element
let select = document.getElementsByClassName('lstSelected')[0],
options = select.options,
len = options.length,
data='',
i=0;
while (i<len){
if (options[i].selected)
data+= "&" + select.name + '=' + options[i].value;
i++;
}
return data;
Data is in the form of query string i.e.name=value&name=anotherValue
I would first create a DataTable
with the columns that you require, then populate it via Linq-to-XML.
You could use a Select query to create an object that represents each row, then use the standard approach for creating DataRows for each item ...
class Quest
{
public string Answer1;
public string Answer2;
public string Answer3;
public string Answer4;
}
public static void Main()
{
var doc = XDocument.Load("filename.xml");
var rows = doc.Descendants("QuestId").Select(el => new Quest
{
Answer1 = el.Element("Answer1").Value,
Answer2 = el.Element("Answer2").Value,
Answer3 = el.Element("Answer3").Value,
Answer4 = el.Element("Answer4").Value,
});
// iterate over the rows and add to DataTable ...
}
If you have control over class loading, you can do static initializing from there.
Example:
class MyClass { public static function static_init() { } }
in your class loader, do the following:
include($path . $klass . PHP_EXT);
if(method_exists($klass, 'static_init')) { $klass::staticInit() }
A more heavy weight solution would be to use an interface with ReflectionClass:
interface StaticInit { public static function staticInit() { } }
class MyClass implements StaticInit { public static function staticInit() { } }
in your class loader, do the following:
$rc = new ReflectionClass($klass);
if(in_array('StaticInit', $rc->getInterfaceNames())) { $klass::staticInit() }
I know this was posted a while ago, but in case anyone is searching for an answer and really wants to use a button element instead of an input element...
You can not use .attr('value')
or .val()
with a button in IE. IE reports both the .val() and .attr("value") as being the text label (content) of the button element instead of the actual value of the value attribute.
You can work around it by temporarily removing the button's label:
var getButtonValue = function($button) {
var label = $button.text();
$button.text('');
var buttonValue = $button.val();
$button.text(label);
return buttonValue;
}
There are a few other quirks with buttons in IE. I have posted a fix for the two most common issues here.
You can place your tables in a div and add style to your table "float: left"
<div>
<table style="float: left">
<tr>
<td>..</td>
</tr>
</table>
<table style="float: left">
<tr>
<td>..</td>
</tr>
</table>
</div>
or simply use css:
div>table {
float: left
}
Final answer was a combination of two of the above (I've upvoted both to show my appreciation!):
select case
when exists (
SELECT 1
FROM Sys.columns c
WHERE c.[object_id] = OBJECT_ID('dbo.Tags')
AND c.name = 'ModifiedByUserId'
)
then 1
else 0
end
Quoting API on referencedColumnName:
The name of the column referenced by this foreign key column.
Default (only applies if single join column is being used): The same name as the primary key column of the referenced table.
Where this would be used?
When there is a composite PK in referenced table, then you need to specify column name you are referencing.
Another base R solution would be to split
the data frame per cat
, after that using lapply
: add a column with number 1:nrow(x)
. The last step is to have your final data frame back with do.call
, that is:
df_split <- split(df, df$cat)
df_lapply <- lapply(df_split, function(x) {
x$num <- seq_len(nrow(x))
return(x)
})
df <- do.call(rbind, df_lapply)
I would go with Larry K's solution, but you can also set the display to inline-block if you want the benefits of both block and inline elements.
You can do this in the div tag by inserting:
style="display:inline-block;"
Or in a CSS stylesheet with this method:
div { display:inline-block; }
Hope it helps, but as earlier mentioned, I would personally go for Larry K's solution ;-)
<!--[if lt IE 8]><![endif]-->
The lt in the above statement means less than, so 'if less than IE 8'.
For all versions of IE you can just use
<!--[if IE]><![endif]-->
or for all versions above ie 6 for example.
<!--[if gt IE 6]><![endif]-->
Where gt is 'greater than'
If you would like to write specific styles for versions below and including IE8 you can write
<!--[if lte IE 8]><![endif]-->
where lte is 'less than and equal' to
You can get all checked checkboxes like this:
var boxes = $(":checkbox:checked");
And all non-checked like this:
var nboxes = $(":checkbox:not(:checked)");
You could merely cycle through either one of these collections, and store those names. If anything is absent, you know it either was or wasn't checked. In PHP, if you had an array of names which were checked, you could simply do an in_array()
request to know whether or not any particular box should be checked at a later date.
jQuery also has a serialize method that will maintain the state of your form controls. For instance, the example provided on jQuery's website follows:
single=Single2&multiple=Multiple&multiple=Multiple3&check=check2&radio=radio2
This will enable you to keep the information for which elements were checked as well.
This works even if you are on 32-bit PHP:
list($msec, $sec) = explode(' ', microtime());
$time_milli = $sec.substr($msec, 2, 3); // '1491536422147'
$time_micro = $sec.substr($msec, 2, 6); // '1491536422147300'
Note this doesn't give you integers, but strings. However this works fine in many cases, for example when building URLs for REST requests.
If you need integers, 64-bit PHP is mandatory.
Then you can reuse the above code and cast to (int):
list($msec, $sec) = explode(' ', microtime());
// these parentheses are mandatory otherwise the precedence is wrong!
// ? ?
$time_milli = (int) ($sec.substr($msec, 2, 3)); // 1491536422147
$time_micro = (int) ($sec.substr($msec, 2, 6)); // 1491536422147300
Or you can use the good ol' one-liners:
$time_milli = (int) round(microtime(true) * 1000); // 1491536422147
$time_micro = (int) round(microtime(true) * 1000000); // 1491536422147300
Below are some notes which i pulled from this codeproject article on C# Out Vs Ref
If you are a visual person then please see this yourtube video which demonstrates the difference practically https://www.youtube.com/watch?v=lYdcY5zulXA
Below image shows the differences more visually
To enable GZIP compression, you need to modify the configuration of the embedded Tomcat instance. To do so, you declare a EmbeddedServletContainerCustomizer
bean in your Java configuration and then register a TomcatConnectorCustomizer
with it.
For example:
@Bean
public EmbeddedServletContainerCustomizer servletContainerCustomizer() {
return new EmbeddedServletContainerCustomizer() {
@Override
public void customize(ConfigurableEmbeddedServletContainerFactory factory) {
((TomcatEmbeddedServletContainerFactory) factory).addConnectorCustomizers(new TomcatConnectorCustomizer() {
@Override
public void customize(Connector connector) {
AbstractHttp11Protocol httpProtocol = (AbstractHttp11Protocol) connector.getProtocolHandler();
httpProtocol.setCompression("on");
httpProtocol.setCompressionMinSize(64);
}
});
}
};
}
See the Tomcat documentation for more details on the various compression configuration options that are available.
You say that you want to selectively enable compression. Depending on your selection criteria, then the above approach may be sufficient. It enables you to control compression by the request's user-agent, the response's size, and the response's mime type.
If this doesn't meet your needs then I believe you will have to perform the compression in your controller and return a byte[] response with a gzip content-encoding header.
if you have added a new line, Make sure you have added next line syntax in previous line. typically if "\" is missing in your previous line of changes, you will get this error.

(months later) a tiny real example where lambda is useful, partial not:
say you want various 1-dimensional cross-sections through a 2-dimensional function,
like slices through a row of hills.
quadf( x, f )
takes a 1-d f
and calls it for various x
.
To call it for vertical cuts at y = -1 0 1 and horizontal cuts at x = -1 0 1,
fx1 = quadf( x, lambda x: f( x, 1 ))
fx0 = quadf( x, lambda x: f( x, 0 ))
fx_1 = quadf( x, lambda x: f( x, -1 ))
fxy = parabola( y, fx_1, fx0, fx1 )
f_1y = quadf( y, lambda y: f( -1, y ))
f0y = quadf( y, lambda y: f( 0, y ))
f1y = quadf( y, lambda y: f( 1, y ))
fyx = parabola( x, f_1y, f0y, f1y )
As far as I know, partial
can't do this --
quadf( y, partial( f, x=1 ))
TypeError: f() got multiple values for keyword argument 'x'
(How to add tags numpy, partial, lambda to this ?)
A handle is a unique identifier for an object managed by Windows. It's like a pointer, but not a pointer in the sence that it's not an address that could be dereferenced by user code to gain access to some data. Instead a handle is to be passed to a set of functions that can perform actions on the object the handle identifies.
If you're inserting text content in your document in a location where text content is expected1, you typically only need to escape the same characters as you would in XML. Inside of an element, this just includes the entity escape ampersand &
and the element delimiter less-than and greater-than signs <
>
:
& becomes &
< becomes <
> becomes >
Inside of attribute values you must also escape the quote character you're using:
" becomes "
' becomes '
In some cases it may be safe to skip escaping some of these characters, but I encourage you to escape all five in all cases to reduce the chance of making a mistake.
If your document encoding does not support all of the characters that you're using, such as if you're trying to use emoji in an ASCII-encoded document, you also need to escape those. Most documents these days are encoded using the fully Unicode-supporting UTF-8 encoding where this won't be necessary.
In general, you should not escape spaces as
.
is not a normal space, it's a non-breaking space. You can use these instead of normal spaces to prevent a line break from being inserted between two words, or to insert extra space without it being automatically collapsed, but this is usually a rare case. Don't do this unless you have a design constraint that requires it.
1 By "a location where text content is expected", I mean inside of an element or quoted attribute value where normal parsing rules apply. For example: <p>HERE</p>
or <p title="HERE">...</p>
. What I wrote above does not apply to content that has special parsing rules or meaning, such as inside of a script or style tag, or as an element or attribute name. For example: <NOT-HERE>...</NOT-HERE>
, <script>NOT-HERE</script>
, <style>NOT-HERE</style>
, or <p NOT-HERE="...">...</p>
.
In these contexts, the rules are more complicated and it's much easier to introduce a security vulnerability. I strongly discourage you from ever inserting dynamic content in any of these locations. I have seen teams of competent security-aware developers introduce vulnerabilities by assuming that they had encoded these values correctly, but missing an edge case. There's usually a safer alternative, such as putting the dynamic value in an attribute and then handling it with JavaScript.
If you must, please read the Open Web Application Security Project's XSS Prevention Rules to help understand some of the concerns you will need to keep in mind.
If you're using a standard POSIX OS, you use cron.
If you're using Windows, you use at.
Write a Django management command to
Figure out what platform they're on.
Either execute the appropriate "AT" command for your users, or update the crontab for your users.
If your input
is in a form
and you want to get value after submit you can do like
<form onsubmit="submitLoginForm(event)">
<input type="text" name="name">
<input type="password" name="password">
<input type="submit" value="Login">
</form>
<script type="text/javascript">
function submitLoginForm(event){
event.preventDefault();
console.log(event.target['name'].value);
console.log(event.target['password'].value);
}
</script>
Benefit of this way: Example your page have 2 form
for input sender
and receiver
information.
If you don't use form
for get value then
- You can set 2 different id
(or tag
or name
...) for each field like sender-name
and receiver-name
, sender-address
and receiver-address
, ...
- If you set same value for 2 input, then after getElementsByName
(or getElementsByTagName
...) you need to remember 0 or 1 is sender
or receiver
. Later if you change the order of 2 form
in html, you need to check this code again
If you use form
, then you can use name
, address
, ...
Or, if you want to avoid the use of a global variable you could use the rarely used .Tag
property of the userform:
Private Sub CommandButton1_Click()
Me.CommandButton1.Enabled = False 'Disabling button so user cannot push it
'multiple times
Me.CommandButton1.caption = "Wait..." 'Jamie's suggestion
Me.Tag = "Cancel"
End Sub
Private Sub SomeVBASub
If LCase(UserForm1.Tag) = "cancel" Then
GoTo StopProcess
Else
'DoStuff
End If
Exit Sub
StopProcess:
'Here you can do some steps to be able to cancel process adequately
'i.e. setting collections to "Nothing" deleting some files...
End Sub
You are getting that error because the keytool
executable is under the bin
directory, not the lib
directory in your example. And you will need to add the location of your keystore
as well in the command line. There is a pretty good reference to all of this here - Jrun Help / Import certificates | Certificate stores | ColdFusion
The default truststore is the JRE's cacerts file. This file is typically located in the following places:
Server Configuration:
cf_root/runtime/jre/lib/security/cacerts
Multiserver/J2EE on JRun 4 Configuration:
jrun_root/jre/lib/security/cacerts
Sun JDK installation:
jdk_root/jre/lib/security/cacerts
Consult documentation for other J2EE application servers and JVMs
The keytool is part of the Java SDK and can be found in the following places:
Server Configuration:
cf_root/runtime/bin/keytool
Multiserver/J2EE on JRun 4 Configuration:
jrun_root/jre/bin/keytool
Sun JDK installation:
jdk_root/bin/keytool
Consult documentation for other J2EE application servers and JVMs
So if you navigate to the directory where the keytool
executable is located your command line would look something like this:
keytool -list -v -keystore JAVA_HOME\jre\lib\security\cacert -storepass changeit
You will need to supply pathing information depending on where you run the keytool command from and where your certificate file resides.
Also, be sure you are updating the correct cacerts file that ColdFusion is using. In case you have more than one JRE installed on that server. You can verify the JRE ColdFusion is using from the administrator under the 'System Information'. Look for the Java Home line.
You can use #
at the beginning of a line to start a comment (whitespaces before #
are allowed):
# do some stuff
RUN apt-get update \
# install some packages
apt-get install -y cron
#
's in the middle of a string are passed to the command itself, e.g.:
RUN echo 'we are running some # of cool things'
use the limit clausule, with the offset to choose the row number -1 so if u wanna get the number 8 row so use:
limit 1 offset 7
try:
git ls-files --error-unmatch <file name>
will exit with 1 if file is not tracked
For Angular you should simply use formatDate
instead of the DatePipe
.
import {formatDate} from '@angular/common';

this.dateString = formatDate(Date.now(),'yyyy-MM-dd',this.locale);
}
Let's create one module with 2 ways:
One way
var aa = {
a: () => {return 'a'},
b: () => {return 'b'}
}
module.exports = aa;
Second way
exports.a = () => {return 'a';}
exports.b = () => {return 'b';}
And this is how require() will integrate module.
First way:
function require(){
module.exports = {};
var exports = module.exports;
var aa = {
a: () => {return 'a'},
b: () => {return 'b'}
}
module.exports = aa;
return module.exports;
}
Second way
function require(){
module.exports = {};
var exports = module.exports;
exports.a = () => {return 'a';}
exports.b = () => {return 'b';}
return module.exports;
}
The jQuery Audit plugin plugin should let you do this through the normal Chrome Dev Tools. It's not perfect, but it should let you see the actual handler bound to the element/event and not just the generic jQuery handler.
Try one of the following, depending on your image format:
UIImageJPEGRepresentation
Returns the data for the specified image in JPEG format.
NSData * UIImageJPEGRepresentation (
UIImage *image,
CGFloat compressionQuality
);
UIImagePNGRepresentation
Returns the data for the specified image in PNG format
NSData * UIImagePNGRepresentation (
UIImage *image
);
EDIT:
if you want to access the raw bytes that make up the UIImage, you could use this approach:
CGDataProviderRef provider = CGImageGetDataProvider(image.CGImage);
NSData* data = (id)CFBridgingRelease(CGDataProviderCopyData(provider));
const uint8_t* bytes = [data bytes];
This will give you the low-level representation of the image RGB pixels.
(Omit the CFBridgingRelease
bit if you are not using ARC).
I would use buildAndExpand
from UriComponentsBuilder
to pass all types of URI parameters.
For example:
String url = "http://test.com/solarSystem/planets/{planet}/moons/{moon}";
// URI (URL) parameters
Map<String, String> urlParams = new HashMap<>();
urlParams.put("planets", "Mars");
urlParams.put("moons", "Phobos");
// Query parameters
UriComponentsBuilder builder = UriComponentsBuilder.fromUriString(url)
// Add query parameter
.queryParam("firstName", "Mark")
.queryParam("lastName", "Watney");
System.out.println(builder.buildAndExpand(urlParams).toUri());
/**
* Console output:
* http://test.com/solarSystem/planets/Mars/moons/Phobos?firstName=Mark&lastName=Watney
*/
restTemplate.exchange(builder.buildAndExpand(urlParams).toUri() , HttpMethod.PUT,
requestEntity, class_p);
/**
* Log entry:
* org.springframework.web.client.RestTemplate Created PUT request for "http://test.com/solarSystem/planets/Mars/moons/Phobos?firstName=Mark&lastName=Watney"

If you have trouble viewing the .env file or it is not showing up in the project just do this: ls -a

This allows to see the hidden files in Linux. You can also open the folder with Visual Studio Code and you will see the files and be able to modify them.
Try mpstat
from the sysstat

or grep
to parse the info you need:
mpstat | grep -A 5 "%idle" | tail -n 1 | awk -F " " '{print 100 - $ 12}'a

I don't see any mention of flexbox in here, so I will illustrate:
HTML
<div class="wrapper">
<div class="main">top</div>
<div class="footer">bottom</div>
</div>
CSS
.wrapper {
display: flex;
flex-direction: column;
min-height: 100vh;
}
.main {
flex: 1;
}
.footer {
flex: 0;
}
why not simply
public Date(){
data = new int[]{0,0,0};
}
the reason you got the error is because int[] data = ...
declares a new variable and hides the field data
however it should be noted that the contents of the array are already initialized to 0 (the default value of int
)
You can do it by using window_handles
and switch_to_window
method.
Before clicking the link first store the window handle as
window_before = driver.window_handles[0]
after clicking the link store the window handle of newly opened window as
window_after = driver.window_handles[1]
then execute the switch to window method to move to newly opened window
driver.switch_to_window(window_after)
and similarly you can switch between old and new window. Following is the code example
import unittest
from selenium import webdriver
class GoogleOrgSearch(unittest.TestCase):
def setUp(self):
self.driver = webdriver.Firefox()
def test_google_search_page(self):
driver = self.driver
driver.get("http://www.cdot.in")
window_before = driver.window_handles[0]
print window_before
driver.find_element_by_xpath("//a[@href='http://www.cdot.in/home.htm']").click()
window_after = driver.window_handles[1]
driver.switch_to_window(window_after)
print window_after
driver.find_element_by_link_text("ATM").click()
driver.switch_to_window(window_before)
def tearDown(self):
self.driver.close()
if __name__ == "__main__":
unittest.main()
You can use with reduce
:
let randomNumbers = [4, 7, 1, 9, 6, 5, 6, 9]
let maxNumber = randomNumbers.reduce(randomNumbers[0]) { $0 > $1 ? $0 : $1 } //result is 9
I ran into the same issue today when trying to use a pod written in Objective-C in my Swift project, none of the above solutions seemed to work.
In the podfile I had use_frameworks!

This is how I did this so that only one progress dialog can be open at a time. Based off of the answer from Suraj Bajaj
private ProgressDialog progress;
public void showLoadingDialog() {
if (progress == null) {
progress = new ProgressDialog(this);
progress.setTitle(getString(R.string.loading_title));
progress.setMessage(getString(R.string.loading_message));
}
progress.show();
}
public void dismissLoadingDialog() {
if (progress != null && progress.isShowing()) {
progress.dismiss();
}
}
I also had to use
protected void onResume() {
dismissLoadingDialog();
super.onResume();
}
max_connections
You can change max_connections
while MySQL is running via SET
:
mysql> SET GLOBAL max_connections = 5000;
Query OK, 0 rows affected (0.00 sec)
mysql> SHOW VARIABLES LIKE "max_connections";
+-----------------+-------+
| Variable_name | Value |
+-----------------+-------+
| max_connections | 5000 |
+-----------------+-------+
1 row in set (0.00 sec)
timeout
relatedI had never seen your error message before, so I googled. probably, you are using Connector/Net. Connector/Net Manual says there is max connection pool size. (default is 100) see table 22.21.
I suggest that you increase this value to 100k or disable connection pooling Pooling=false
he has two questions.
Q1 - what happens if I disable pooling
Slow down making DB connection. connection pooling
is a mechanism that use already made DB connection. cost of Making new connection is high. http://en.wikipedia.org/wiki/Connection_pool
Q2 - Can the value of pooling be increased or the maximum is 100?
you can increase but I'm sure what is MAX value, maybe max_connections
in my.cnf
My suggestion is that do not turn off Pooling, increase value by 100 until there is no connection error.
If you have Stress Test tool like JMeter
you can test youself.
If you use Modernizr, it is very easy to use Modernizr.touch
as mentioned earlier.
However, I prefer using a combination of Modernizr.touch
and user agent testing, just to be safe.
var deviceAgent = navigator.userAgent.toLowerCase();
var isTouchDevice = Modernizr.touch ||
(deviceAgent.match(/(iphone|ipod|ipad)/) ||
deviceAgent.match(/(android)/) ||
deviceAgent.match(/(iemobile)/) ||
deviceAgent.match(/iphone/i) ||
deviceAgent.match(/ipad/i) ||
deviceAgent.match(/ipod/i) ||
deviceAgent.match(/blackberry/i) ||
deviceAgent.match(/bada/i));
if (isTouchDevice) {
//Do something touchy
} else {
//Can't touch this
}
If you don't use Modernizr, you can simply replace the Modernizr.touch
function above with ('ontouchstart' in document.documentElement)
Also note that testing the user agent iemobile
will give you broader range of detected Microsoft mobile devices than Windows Phone
.
People are confusing about what closure is. Closure is not the inner function. the meaning of closure is act of closing. So inner function is closing over a nonlocal variable which is called free variable.
def counter_in(initial_value=0):
# initial_value is the free variable
def inc(increment=1):
nonlocal initial_value
initial_value += increment
return print(initial_value)
return inc
when you call counter_in()
this will return inc
function which has a free variable initial_value
. So we created a CLOSURE. people call inc
as closure function and I think this is confusing people, people think "ok inner functions are closures". in reality inc
is not a closure, since it is part of the closure, to make life easy, they call it closure function.
myClosingOverFunc=counter_in(2)
this returns inc
function which is closing over the free variable initial_value
. when you invoke myClosingOverFunc
myClosingOverFunc()
it will print 2.
when python sees that a closure sytem exists, it creates a new obj called CELL. this will store only the name of the free variable which is initial_value
in this case. This Cell obj will point to another object which stores the value of the initial_value
.
in our example, initial_value
in outer function and inner function will point to this cell object, and this cell object will be point to the value of the initial_value
.
variable initial_value =====>> CELL ==========>> value of initial_value
So when you call counter_in
its scope is gone, but it does not matter. because variable initial_value
is directly referencing the CELL Obj. and it indirectly references the value of initial_value
. That is why even though scope of outer function is gone, inner function will still have access to the free variable
let's say I want to write a function, which takes in a function as an arg and returns how many times this function is called.
def counter(fn):
# since cnt is a free var, python will create a cell and this cell will point to the value of cnt
# every time cnt changes, cell will be pointing to the new value
cnt = 0
def inner(*args, **kwargs):
# we cannot modidy cnt with out nonlocal
nonlocal cnt
cnt += 1
print(f'{fn.__name__} has been called {cnt} times')
# we are calling fn indirectly via the closue inner
return fn(*args, **kwargs)
return inner
in this example cnt
is our free variable and inner
+ cnt
create CLOSURE. when python sees this it will create a CELL Obj and cnt
will always directly reference this cell obj and CELL will reference the another obj in the memory which stores the value of cnt
. initially cnt=0.
cnt ======>>>> CELL =============> 0
when you invoke the inner function wih passing a parameter counter(myFunc)()
this will increase the cnt by 1. so our referencing schema will change as follow:
cnt ======>>>> CELL =============> 1 #first counter(myFunc)()
cnt ======>>>> CELL =============> 2 #second counter(myFunc)()
cnt ======>>>> CELL =============> 3 #third counter(myFunc)()
this is only one instance of closure. You can create multiple instances of closure with passing another function
counter(differentFunc)()
this will create a different CELL obj from the above. We just have created another closure instance.
cnt ======>> difCELL ========> 1 #first counter(differentFunc)()
cnt ======>> difCELL ========> 2 #secon counter(differentFunc)()
cnt ======>> difCELL ========> 3 #third counter(differentFunc)()
You can do something like this:
<%!
String myMethod(String input) {
return "test " + input;
}
%>
<%= myMethod("1 2 3") %>
This will output test 1 2 3
to the page.
oracleserviceorcl
service. (From services in Task Manager)ORACLE_SID
variable with orcl
value. (In environment variables)You'll need to run this command from the MySQL prompt:
REPAIR TABLE tbl_name USE_FRM;
From MySQL's documentation on the Repair command:
The USE_FRM option is available for use if the .MYI index file is missing or if its header is corrupted. This option tells MySQL not to trust the information in the .MYI file header and to re-create it using information from the .frm file. This kind of repair cannot be done with myisamchk.
Just add the following line in your build.sbt
PlayKeys.devSettings := Seq("play.server.http.port" -> "8080")
There are several options, including using the method you demonstrate, With, and using a variable.
My preference is option 4 below: Dim
a variable of type Worksheet
and store the worksheet and call the methods on the variable or pass it to functions, however any of the options work.
Sub Test()
Dim SheetName As String
Dim SearchText As String
Dim FoundRange As Range
SheetName = "test"
SearchText = "abc"
' 0. If you know the sheet is the ActiveSheet, you can use if directly.
Set FoundRange = ActiveSheet.UsedRange.Find(What:=SearchText)
' Since I usually have a lot of Subs/Functions, I don't use this method often.
' If I do, I store it in a variable to make it easy to change in the future or
' to pass to functions, e.g.: Set MySheet = ActiveSheet
' If your methods need to work with multiple worksheets at the same time, using
' ActiveSheet probably isn't a good idea and you should just specify the sheets.
' 1. Using Sheets or Worksheets (Least efficient if repeating or calling multiple times)
Set FoundRange = Sheets(SheetName).UsedRange.Find(What:=SearchText)
Set FoundRange = Worksheets(SheetName).UsedRange.Find(What:=SearchText)
' 2. Using Named Sheet, i.e. Sheet1 (if Worksheet is named "Sheet1"). The
' sheet names use the title/name of the worksheet, however the name must
' be a valid VBA identifier (no spaces or special characters. Use the Object
' Browser to find the sheet names if it isn't obvious. (More efficient than #1)
Set FoundRange = Sheet1.UsedRange.Find(What:=SearchText)
' 3. Using "With" (more efficient than #1)
With Sheets(SheetName)
Set FoundRange = .UsedRange.Find(What:=SearchText)
End With
' or possibly...
With Sheets(SheetName).UsedRange
Set FoundRange = .Find(What:=SearchText)
End With
' 4. Using Worksheet variable (more efficient than 1)
Dim MySheet As Worksheet
Set MySheet = Worksheets(SheetName)
Set FoundRange = MySheet.UsedRange.Find(What:=SearchText)
' Calling a Function/Sub
Test2 Sheets(SheetName) ' Option 1
Test2 Sheet1 ' Option 2
Test2 MySheet ' Option 4
End Sub
Sub Test2(TestSheet As Worksheet)
Dim RowIndex As Long
For RowIndex = 1 To TestSheet.UsedRange.Rows.Count
If TestSheet.Cells(RowIndex, 1).Value = "SomeValue" Then
' Do something
End If
Next RowIndex
End Sub
SQL doesn't return any ordering by default because it's faster this way. It doesn't have to go through your data first and then decide what to do.
You need to add an order by clause, and probably order by which ever ID you expect. (There's a duplicate of names, thus I'd assume you want One.ID)
select * From one
inner join two
ON one.one_name = two.one_name
ORDER BY one.ID
Hold down the Alt key and drag the pictures to snap to the upper left corner of the cell.
Format the picture and in the Properties tab select "Move but don't size with cells"
Now you can sort the data table by any column and the pictures will stay with the respective data.
This post at SuperUser has a bit more background and screenshots: https://superuser.com/questions/712622/put-an-equation-object-in-an-excel-cell/712627#712627
In addition to the solution with 'aaaaaaaa' LIKE '%' || tag_name || '%'
there
are position
(reversed order of args) and strpos
.
SELECT id FROM TAG_TABLE WHERE strpos('aaaaaaaa', tag_name) > 0
Besides what is more efficient (LIKE looks less efficient, but an index might change things), there is a very minor issue with LIKE: tag_name of course should not contain %
and especially _
(single char wildcard), to give no false positives.
The simplest way to get images, videos, etc onto the simulator is to drag and drop them from your computer onto the simulator. This will cause the Simulator to open the Photos app and start populating the library.
If you want a scriptable method, read on.
Note - while this is valid, and works, I think Koen's solution below is now a better one, since it does not require rebooting the simulator.
Identify your simulator by going to xCode->Devices, selecting your simulator, and checking the Identifier value. Or you can ensure the simulator is running and run the following to get the device ID xcrun simctl list | grep Booted
Go to
~/Library/Developer/CoreSimulator/Devices/[Simulator Identifier]/data/Media/DCIM/100APPLE
and add IMG_nnnn.THM and IMG_nnnn.JPG. You will then need to reset your simulator (Hardware->Reboot) to allow it to notice the new changes. It doesn't matter if they are not JPEGs - they can both be PNGs, but it appears that both of them must be present for it to work. You may need to create DCIM if it doesn't already exist, and in that case you should start nnnn from 0001. The JPG files are the fullsize version, while the THM files are the thumbnail, and are 75x75 pixels in size. I wrote a script to do this, but there's a better documented one over here(-link no longer work).
You can also add photos from safari in the simulator, by Tapping and Holding on the image. If you drag an image (or any other file, like a PDF) to the simulator, it will immediately open Safari and display the image, so this is quite an easy way of getting images to it.
You're talking about histograms, but this doesn't quite make sense. Histograms and bar charts are different things. An histogram would be a bar chart representing the sum of values per year, for example. Here, you just seem to be after bars.
Here is a complete example from your data that shows a bar of for each required value at each date:
import pylab as pl
import datetime
data = """0 14-11-2003
1 15-03-1999
12 04-12-2012
33 09-05-2007
44 16-08-1998
55 25-07-2001
76 31-12-2011
87 25-06-1993
118 16-02-1995
119 10-02-1981
145 03-05-2014"""
values = []
dates = []
for line in data.split("\n"):
x, y = line.split()
values.append(int(x))
dates.append(datetime.datetime.strptime(y, "%d-%m-%Y").date())
fig = pl.figure()
ax = pl.subplot(111)
ax.bar(dates, values, width=100)
ax.xaxis_date()
You need to parse the date with strptime
and set the x-axis to use dates (as described in this answer).
If you're not interested in having the x-axis show a linear time scale, but just want bars with labels, you can do this instead:
fig = pl.figure()
ax = pl.subplot(111)
ax.bar(range(len(dates)), values)
EDIT: Following comments, for all the ticks, and for them to be centred, pass the range to set_ticks
(and move them by half the bar width):
fig = pl.figure()
ax = pl.subplot(111)
width=0.8
ax.bar(range(len(dates)), values, width=width)
ax.set_xticks(np.arange(len(dates)) + width/2)
ax.set_xticklabels(dates, rotation=90)
You can use any of the following:
\b #A word break and will work for both spaces and end of lines.
(^|\s) #the | means or. () is a capturing group.
/\b(stackoverflow)\b/
Also, if you don't want to include the space in your match, you can use lookbehind/aheads.
(?<=\s|^) #to look behind the match
(stackoverflow) #the string you want. () optional
(?=\s|$) #to look ahead.
I ran into this problem debugging play framework version 2.x, turned out the server hadn't been started even though the play debug run command was issued. After a first request to the webserver which caused the play framework to really start the application at port 9000, I was able to connect properly to the debug port 9999 from eclipse.
[info] play - Application started (Dev)
The text above was shown in the console when the message above appeared, indicating why eclipse couldn't connect before first http request.
Use the UNC path rather than HTTP. This code works:
Public Sub ListFiles()
Dim folder As folder
Dim f As File
Dim fs As New FileSystemObject
Dim RowCtr As Integer
RowCtr = 1
Set folder = fs.GetFolder("\\SharePointServer\Path\MorePath\DocumentLibrary\Folder")
For Each f In folder.Files
Cells(RowCtr, 1).Value = f.Name
RowCtr = RowCtr + 1
Next f
End Sub
To get the UNC path to use, go into the folder in the document library, drop down the Actions menu and choose Open in Windows Explorer. Copy the path you see there and use that.
You can use a combination of JSON.stringify
, its replacer parameter, and JSON.parse
to turn it back into an object. Using this method also means the replacement is done to all nested keys within nested objects.
Example Object
var exampleObject = {
string: 'value',
emptyString: '',
integer: 0,
nullValue: null,
array: [1, 2, 3],
object: {
string: 'value',
emptyString: '',
integer: 0,
nullValue: null,
array: [1, 2, 3]
},
arrayOfObjects: [
{
string: 'value',
emptyString: '',
integer: 0,
nullValue: null,
array: [1, 2, 3]
},
{
string: 'value',
emptyString: '',
integer: 0,
nullValue: null,
array: [1, 2, 3]
}
]
};
Replacer Function
function replaceUndefinedOrNull(key, value) {
if (value === null || value === undefined) {
return undefined;
}
return value;
}
Clean the Object
exampleObject = JSON.stringify(exampleObject, replaceUndefinedOrNull);
exampleObject = JSON.parse(exampleObject);
As others have said, it is not possible to directly lookup a parent from a nested child. All of the proposed solutions advise various different ways of referring back to the parent object or parent scope through an explicit variable name.
However, directly traversing up to the the parent object is possible if you employ recursive ES6 Proxies on the parent object.
I've written a library called ObservableSlim that, among other things, allows you to traverse up from a child object to the parent.
Here's a simple example (jsFiddle demo):
var test = {"hello":{"foo":{"bar":"world"}}};
var proxy = ObservableSlim.create(test, true, function() { return false });
function traverseUp(childObj) {
console.log(JSON.stringify(childObj.__getParent())); // returns test.hello: {"foo":{"bar":"world"}}
console.log(childObj.__getParent(2)); // attempts to traverse up two levels, returns undefined because test.hello does not have a parent object
};
traverseUp(proxy.hello.foo);
I've done it this way in the past, JsFiddle:
CSS:
.radio-option {
cursor: pointer;
height: 23px;
width: 23px;
background: url(../images/checkbox2.png) no-repeat 0px 0px;
}
.radio-option.click {
background: url(../images/checkbox1.png) no-repeat 0px 0px;
}
HTML:
<li><div class="radio-option"></div></li>
<li><div class="radio-option"></div></li>
<li><div class="radio-option"></div></li>
<li><div class="radio-option"></div></li>
<li><div class="radio-option"></div></li>
jQuery:
<script>
$(document).ready(function() {
$('.radio-option').click(function () {
$(this).not(this).removeClass('click');
$(this).toggleClass("click");
});
});
</script>
I have found that you can edit the size of the UIPickerView - just not with interface builder. open the .xib file with a text editor and set the size of the picker view to whatever you want. Interface builder does not reset the size and it seems to work. I'm sure apple locked the size for a reason so you'll have to experiment with different sizes to see what works.
You can try export http_proxy=http://your_proxy:your_port
Check and try below things. Issue should be resolved.
First of all check your log from bottom of the build window whether any error related to project showing or not. If error showing then fix all of those. Now build and run again fix all of the error comes up. It will eliminate aapt2 issue without changing android gradle plugin to 3.2.0.
Secondly if there is not any project related error showing in the build log but still showing aapt2 error then you can fix it by following below steps.
Update your android gradle plugin in your project level build.gradle
file like below:
classpath 'com.android.tools.build:gradle:3.2.0-alpha13'
Now update android.enableAapt2=true
. Then check and build your project.
Any of these steps should work to fix aapt related issues.
The previous version, xlrd 1.2.0, may appear to work, but it could also expose you to potential security vulnerabilities. With that warning out of the way, if you still want to give it a go, type the following command:
pip install xlrd==1.2.0
Can't you get a free version of Visual Studio Student Addition from your school? Most Universities have programs to give free software to students.
A JAR is basically a ZIP file so treat it as such. Below contains an example on how to extract one file from a WAR file (also treat it as a ZIP file) and outputs the string contents. For binary you'll need to modify the extraction process, but there are plenty of examples out there for that.
public static void main(String args[]) {
String relativeFilePath = "style/someCSSFile.css";
String zipFilePath = "/someDirectory/someWarFile.war";
String contents = readZipFile(zipFilePath,relativeFilePath);
System.out.println(contents);
}
public static String readZipFile(String zipFilePath, String relativeFilePath) {
try {
ZipFile zipFile = new ZipFile(zipFilePath);
Enumeration<? extends ZipEntry> e = zipFile.entries();
while (e.hasMoreElements()) {
ZipEntry entry = (ZipEntry) e.nextElement();
// if the entry is not directory and matches relative file then extract it
if (!entry.isDirectory() && entry.getName().equals(relativeFilePath)) {
BufferedInputStream bis = new BufferedInputStream(
zipFile.getInputStream(entry));
// Read the file
// With Apache Commons I/O
String fileContentsStr = IOUtils.toString(bis, "UTF-8");
// With Guava
//String fileContentsStr = new String(ByteStreams.toByteArray(bis),Charsets.UTF_8);
// close the input stream.
bis.close();
return fileContentsStr;
} else {
continue;
}
}
} catch (IOException e) {
logger.error("IOError :" + e);
e.printStackTrace();
}
return null;
}
In this example I'm using Apache Commons I/O and if you are using Maven here is the dependency:
<dependency>
<groupId>commons-io</groupId>
<artifactId>commons-io</artifactId>
<version>2.4</version>
</dependency>
Using table
:

# 1 Amy 2
# 2 Dave 1
# 3 Jack 3
# 4 Larry 1
# 5 Tom 2
This error occurs when the client URL and server URL don't match, including the port number. In this case you need to enable your service for CORS which is cross origin resource sharing.
If you are hosting a Spring REST service then you can find it in the blog post CORS support in Spring Framework.
If you are hosting a service using a Node.js server then
npm install cors --save
Add following lines to your server.js
var cors = require('cors')
app.use(cors()) // Use this after the variable declaration
Call Path.GetFullPath
; it will throw exceptions if the path is invalid.
To disallow relative paths (such as Word
), call Path.IsPathRooted
.
I had this problem working with pycurl and I solved it using
c.setopt(pycurl.HTTP_VERSION, pycurl.CURL_HTTP_VERSION_1_0)
like Eric Caron says.
Swift 5 You can use a UIView extension so that you can add bottom border to any view:
extension UIView {
func addBottomLine(width: CGFloat, color: UIColor) {
let lineView: UIView = {
let view = UIView()
view.translatesAutoresizingMaskIntoConstraints = false
view.backgroundColor = color
return view
}()
addSubview(lineView)
NSLayoutConstraint.activate([
lineView.heightAnchor.constraint(equalToConstant: width),
lineView.leadingAnchor.constraint(equalTo: leadingAnchor),
lineView.trailingAnchor.constraint(equalTo: trailingAnchor),
lineView.bottomAnchor.constraint(equalTo: bottomAnchor)
])
}
}
You can do Server side validation and send back a JSON object with the validation results for each field, keeping client Javascript to a minimum (just displaying results) and still having a user friendly experience without having to repeat yourself on both client and server.
Hiding modal backdrop works but then any subsequent opening of the modal and the backdrop doesn't hide like it should. I found this works consistently:
// SHOW
$('#myModal').modal('show')
$('.modal-backdrop').show();
// HIDE
$('#myModal').modal('hide');
$('.modal-backdrop').hide();
You could use crypto-js.
I would also recommend using SHA256, rather than MD5.
To install crypto-js via NPM:
npm install crypto-js
Alternatively you can use a CDN and reference the JS file.
Then to display a MD5 and SHA256 hash, you can do the following:
<script type="text/javascript">
var md5Hash = CryptoJS.MD5("Test");
var sha256Hash = CryptoJS.SHA256("Test1");
console.log(md5Hash.toString());
console.log(sha256Hash.toString());
</script>
Working example located here, JSFiddle
There are also other JS functions that will generate an MD5
hash, outlined below.

In Notepad++, you can use the Mark tab in the Find dialogue to Bookmark all lines matching your query which can be regex or normal (wildcard).
Then use Search > Bookmark > Remove Bookmarked Lines.
It is not htop-like, but you could use atop. However, to display disk activity per process, it needs a kernel patch (available from the site). These kernel patches are now obsoleted, only to show per-process network activity an optional module is provided.
Use Object.keys()
or shim it in older browsers...
const keys = Object.keys(driversCounter);
If you wanted values, there is Object.values()
and if you want key and value, you can use Object.entries()
, often paired with Array.prototype.forEach()
like this...
Object.entries(driversCounter).forEach(([key, value]) => {
console.log(key, value);
});
Alternatively, considering your use case, maybe this will do it...
var selectBox, option, prop;
selectBox = document.getElementById("drivers");
for (prop in driversCounter) {
option = document.createElement("option");
option.textContent = prop;
option.value = driversCounter[prop];
selectBox.add(option);
}
You can use insert
to specify where you want to new column to be. In this case, I use 0
to place the new column at the left.
df.insert(0, 'Name', 'abc')
Name Date Open High Low Close
0 abc 01-01-2015 565 600 400 450
The following seems to be like the first suggested query above but sometime you have to specify the database to get it to work. Note that the query should also work without specifying the TABLE_SCHEMA:
SELECT COLUMN_NAME
FROM YOUR_DB_NAME.INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'YOUR_TABLE_NAME' AND TABLE_SCHEMA = 'YOUR_DB_NAME'
If you're looking for something as nice as Python's x[-1] notation, I think you're out of luck. The standard idiom is
x[length(x)]
but it's easy enough to write a function to do this:
last <- function(x) { return( x[length(x)] ) }
This missing feature in R annoys me too!
Are you specifically trying to rotate the links only? Because doing it on the LI tags seems to work fine.
According to Snook transforms require the elements affected be block. He's also got some code there to make this work for IE using filters, if you care to add it on(though there appears to be some limitation on values).
You can also get the last command from history and subtract its EndExecutionTime
from its StartExecutionTime
.
.\do_something.ps1
$command = Get-History -Count 1
$command.EndExecutionTime - $command.StartExecutionTime
I had the same problem, I'm using a AfterViewChecked
and @ViewChild
combination (Angular2 beta.3).
The Component:
import {..., AfterViewChecked, ElementRef, ViewChild, OnInit} from 'angular2/core'
@Component({
...
})
export class ChannelComponent implements OnInit, AfterViewChecked {
@ViewChild('scrollMe') private myScrollContainer: ElementRef;
ngOnInit() {
this.scrollToBottom();
}
ngAfterViewChecked() {
this.scrollToBottom();
}
scrollToBottom(): void {
try {
this.myScrollContainer.nativeElement.scrollTop = this.myScrollContainer.nativeElement.scrollHeight;
} catch(err) { }
}
}
The Template:
<div #scrollMe style="overflow: scroll; height: xyz;">
<div class="..."
*ngFor="..."
...>
</div>
</div>
Of course this is pretty basic. The AfterViewChecked
triggers every time the view was checked:
Implement this interface to get notified after every check of your component's view.
If you have an input-field for sending messages for instance this event is fired after each keyup (just to give an example). But if you save whether the user scrolled manually and then skip the scrollToBottom()
you should be fine.
Adding class using element's classList property:
element.classList.add('my-class-name');
Removing:
element.classList.remove('my-class-name');
In most cases, this error is the result of code which tries to instantiate a COM object. For example, here is a piece of code starting up Excel:
Excel.ApplicationClass xlapp = new Excel.ApplicationClass();
Typically, in .NET 4 you just need to remove the 'Class' suffix and compile the code:
Excel.Application xlapp = new Excel.Application();
An MSDN explanation is here.
vertical-align
applies to the elements being aligned, not their parent element. To vertically align the div's children, do this instead:
div > * {
vertical-align:middle; // Align children to middle of line
}
See: http://jsfiddle.net/dfmx123/TFPx8/1186/
NOTE: vertical-align
is relative to the current text line, not the full height of the parent div
. If you wanted the parent div
to be taller and still have the elements vertically centered, set the div
's line-height
property instead of its height
. Follow jsfiddle link above for an example.
If this error arises when manipulating a file that was just opened, check to see if you opened it in 'rb'
mode
Try this
-moz-box-shadow:0 5px 5px rgba(182, 182, 182, 0.75);
-webkit-box-shadow: 0 5px 5px rgba(182, 182, 182, 0.75);
box-shadow: 0 5px 5px rgba(182, 182, 182, 0.75);

Use these commands :-
mysqldump <other mysqldump options> --routines > outputfile.sql
If we want to backup ONLY the stored procedures and triggers and not the mysql tables and data then we should run something like:
mysqldump --routines --no-create-info --no-data --no-create-db --skip-opt <database> > outputfile.sql
If you need to import them to another db/server you will have to run something like:
mysql <database> < outputfile.sql
OK, so I found the answer from http://binglongx.wordpress.com/2009/01/26/visual-c-does-not-generate-lib-file-for-a-dll-project/ says that this problem was caused by not exporting any symbols and further instructs on how to export symbols to create the lib file. To do so, add the following code to your .h file for your DLL.
#ifdef BARNABY_EXPORTS
#define BARNABY_API __declspec(dllexport)
#else
#define BARNABY_API __declspec(dllimport)
#endif
Where BARNABY_EXPORTS and BARNABY_API are unique definitions for your project. Then, each function you export you simply precede by:
BARNABY_API int add(){
}
This problem could have been prevented either by clicking the Export Symbols box on the new project DLL Wizard or by voting yes for lobotomies for computer programmers.
A predicate is a function that returns a true/false (i.e. boolean) value, as opposed to a proposition which is a true/false (i.e. boolean) value. In Java, one cannot have standalone functions, and so one creates a predicate by creating an interface for an object that represents a predicate and then one provides a class that implements that interface. An example of an interface for a predicate might be:
public interface Predicate<ARGTYPE>
{
public boolean evaluate(ARGTYPE arg);
}
And then you might have an implementation such as:
public class Tautology<E> implements Predicate<E>
{
public boolean evaluate(E arg){
return true;
}
}
To get a better conceptual understanding, you might want to read about first-order logic.
Edit
There is a standard Predicate interface (java.util.function.Predicate) defined in the Java API as of Java 8. Prior to Java 8, you may find it convenient to reuse the com.google.common.base.Predicate interface from Guava.
Also, note that as of Java 8, it is much simpler to write predicates by using lambdas. For example, in Java 8 and higher, one can pass p -> true
to a function instead of defining a named Tautology subclass like the above.
I can only assume that your ${project.server.config} property is something custom defined and is outside of the standard directory layout.
If so, then I'd use the copy task.
Another approach could be:
let myList = [{id:'aaa1', name: 'aaa'}, {id:'bbb2', name: 'bbb'}, {id:'ccc3', name: 'ccc'}];
let itemUpdated = {id: 'aaa1', name: 'Another approach'};
myList.find(item => item.id == itemUpdated.id).name = itemUpdated.name;
You can use this, just think Job is the name of the model to which you are adding index cader_id:
class AddCaderIdToJob < ActiveRecord::Migration[5.2]
def change
change_table :jobs do |t|
t.integer :cader_id
t.index :cader_id
end
end
end
SelectionChange is the event built into the Excel Object model for this. It should do exactly as you want, firing any time the user clicks anywhere...
I'm not sure that I understand your objections to global variables here, you would only need 1 if you use the Application.SelectionChange event. However, you wouldn't need any if you utilize the Workbook class code behind (to trap the Workbook.SelectionChange event) or the Worksheet class code behind (to trap the Worksheet.SelectionChange) event. (Unless your issue is the "global variable reset" problem in VBA, for which there is only one solution: error handling everywhere. Do not allow any unhandled errors, instead log them and/or "soft-report" an error as a message box to the user.)
You might also need to trap the Worksheet.Activate() and Worksheet.Deactivate() events (or the equivalent in the Workbook class) and/or the Workbook.Activate and Workbook.Deactivate() events so that you know when the user has switched worksheets and/or workbooks. The Window activate and deactivate events should make this approach complete. They could all call the same exact procedure, however, they all denote the same thing: the user changed the "focus", if you will.
If you don't like VBA, btw, you can do the same using VB.NET or C#.
[Edit: Dbb makes a very good point about the SelectionChange event not picking up a click when the user clicks within the currently selected cell. If you need to pick that up, then you would need to use subclassing.]
How about something like this?
val newDF = df.filter($"B" === "").take(1) match {
case Array() => df
case _ => df.withColumn("D", $"B" === "")
}
Using take(1)
should have a minimal hit

With your private key and public certificate, you need to create a PKCS12 keystore first, then convert it into a JKS.
# Create PKCS12 keystore from private key and public certificate.
openssl pkcs12 -export -name myservercert -in selfsigned.crt -inkey server.key -out keystore.p12
# Convert PKCS12 keystore into a JKS keystore
keytool -importkeystore -destkeystore mykeystore.jks -srckeystore keystore.p12 -srcstoretype pkcs12 -alias myservercert
To verify the contents of the JKS, you can use this command:
keytool -list -v -keystore mykeystore.jks
If this was not a self-signed certificate, you would probably want to follow this step with importing the certificate chain leading up to the trusted CA cert.
React uses the className
attribute, like the DOM.
If you use the development build, and look at the console, there's a warning. You can see this on the jsfiddle.

Any changes you commit, like deleting all your project files, will still be in place after a pull. All a pull does is merge the latest changes from somewhere else into your own branch, and if your branch has deleted everything, then at best you'll get merge conflicts when upstream changes affect files you've deleted. So, in short, yes everything is up to date.
If you describe what outcome you'd like to have instead of "all files deleted", maybe someone can suggest an appropriate course of action.
Update:
GET THE MOST RECENT OF THE CODE ON MY SYSTEM
What you don't seem to understand is that you already have the most recent code, which is yours. If what you really want is to see the most recent of someone else's work that's on the master branch, just do:
git fetch upstream
git checkout upstream/master
Note that this won't leave you in a position to immediately (re)start your own work. If you need to know how to undo something you've done or otherwise revert changes you or someone else have made, then please provide details. Also, consider reading up on what version control is for, since you seem to misunderstand its basic purpose.
