Logical address:- Logical address generated by the CPU . when we are give the problem to the computer then our computer pass the problem to the processor through logical address , which we are not seen this address called logical address .
Physical address :- when our processor create process and solve our problem then we store data in secondary memory through address called physical address
For Angular version 4+, you don't need to use any complex solution. You can simply use [routerLinkActive]="'is-active'"
.
For an example with bootstrap 4 nav link:
<ul class="navbar-nav mr-auto">
<li class="nav-item" routerLinkActive="active">
<a class="nav-link" routerLink="/home">Home</a>
</li>
<li class="nav-item" routerLinkActive="active">
<a class="nav-link" routerLink="/about-us">About Us</a>
</li>
<li class="nav-item" routerLinkActive="active">
<a class="nav-link " routerLink="/contact-us">Contact</a>
</li>
</ul>
My code to convert array to Json
Code
List<String>a = new ArrayList<String>();
a.add("so 1");
a.add("so 2");
a.add("so 3");
JSONArray jray = new JSONArray(a);
System.out.println(jray.toString());
output
["so 1","so 2","so 3"]
when you bind localhost
or 127.0.0.1
, it means you can only connect to your service from local.
you cannot bind 10.0.0.1
because it not belong to you, you can only bind ip owned by your computer
you can bind 0.0.0.0
because it means all ip on your computer, so any ip can connect to your service if they can connect to any of your ip
Your command is completely incorrect. The output format is not rawvideo
and you don't need the bitstream filter h264_mp4toannexb
which is used when you want to convert the h264
contained in an mp4
to the Annex B
format used by MPEG-TS
for example. What you want to use instead is the aac_adtstoasc
for the AAC
streams.
ffmpeg -i http://.../playlist.m3u8 -c copy -bsf:a aac_adtstoasc output.mp4
layout works the same as an master page. any css reference that layout has, any child pages will have.
Here is a simpler method (hack) that gives you back the setdefaultencoding()
function that was deleted from sys
:
import sys
# sys.setdefaultencoding() does not exist, here!
reload(sys) # Reload does the trick!
sys.setdefaultencoding('UTF8')
(Note for Python 3.4+: reload()
is in the importlib
library.)
This is not a safe thing to do, though: this is obviously a hack, since sys.setdefaultencoding()
is purposely removed from sys
when Python starts. Reenabling it and changing the default encoding can break code that relies on ASCII being the default (this code can be third-party, which would generally make fixing it impossible or dangerous).
If the function you called returns null, it means your phone number is not registered in your contact list.
If instead of the phone number you just need an unique number, you may use the sim card's serial number:
TelephonyManager telemamanger = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
String getSimSerialNumber = telemamanger.getSimSerialNumber();
It's very easy:
numb = raw_input('Input Line: ')
fiIn = open('file.txt').readlines()
for lines in fiIn:
if numb == lines[0]:
print lines
For positive numbers
unsigned int x, y, q;
To round up ...
q = (x + y - 1) / y;
or (avoiding overflow in x+y)
q = 1 + ((x - 1) / y); // if x != 0
An XML declaration is not required in all XML documents; however XHTML document authors are strongly encouraged to use XML declarations in all their documents. Such a declaration is required when the character encoding of the document is other than the default UTF-8 or UTF-16 and no encoding was determined by a higher-level protocol. Here is an example of an XHTML document. In this example, the XML declaration is included.
<?xml version="1.0" encoding="UTF-8"?>

Like that, both of the sentences will be executed even before the page has finished loading.
Here is your error, you are missing a ';' Change:
echo 'alert("review your answer")';
echo 'window.location= "index.php"';
To:
echo 'alert("review your answer");';
echo 'window.location= "index.php";';
Then a suggestion: You really should trigger that logic after some event. So, for instance:
document.getElementById("myBtn").onclick=function(){
alert("review your answer");
window.location= "index.php";
};
Another suggestion, use jQuery
You could also do:
SELECT EMP_NAME, DEPT
FROM EMPLOYEE
WHERE TRUNC(TIME_CREATED) = DATE '2011-01-26'
@Cort3z: if the problem is still present, this hotfix: https://support.microsoft.com/en-us/kb/2891362 should solve it (from win7 sp1 to 8.1)
Colin's example for me clashed with the like button. So I adapted it to only target the Like Box.
.fb-like-box, .fb-like-box span, .fb-like-box span iframe[style] { width: 100% !important; }
Tested in most modern browsers.
The link has a fairly good example of when and why you may need to escape &
to &
https://jsfiddle.net/vh2h7usk/1/
Interestingly, I had to escape the character in order to represent it properly in my answer here. If I were to use the built-in code sample option (from the answer panel), I can just type in &
and it appears as it should. But if I were to manually use the <code></code>
element, then I have to escape in order to represent it correctly :)
There is a built in function to compare lists:
Following is the syntax for cmp() method -
cmp(list1, list2)
#!/usr/bin/python
list1, list2 = [123, 'xyz'], [123, 'xyz']
print cmp(list1,list2)
When we run above program, it produces following result -
0
If the result is a tie, meaning that 0 is returned
For input 1,2,3,4,5
the input is of length 9. 9/2 = 4
in integer math, so you're only storing the first four variables, not all 5.
Even if you fixed that, it would break horribly if you passed in an input of 10,11,12,13
It would work (by chance) if you used 1,2,3,4,50
for an input, strangely enough :-)
You would be much better off doing something like this
String[] strArray = input.split(",");
int[] intArray = new int[strArray.length];
for(int i = 0; i < strArray.length; i++) {
intArray[i] = Integer.parseInt(strArray[i]);
}
For future reference, when you get an error, I highly recommend posting it with the code. You might not have someone with a jdk readily available to compile the code to debug it! :)
What you are trying to do is not possible. The reason for this is that in a POSIX system (Linux, OSX, etc), a child process cannot modify the environment of a parent process. This includes modifying the parent process's working directory and environment variables.
When you are on the commandline and you go to execute your Node script, your current process (bash
, zsh
, whatever) spawns a new process which has it's own environment, typically a copy of your current environment (it is possible to change this via system calls; but that's beyond the scope of this reply), allowing that process to do whatever it needs to do in complete isolation. When the subprocess exits, control is handed back to your shell's process, where the environment hasn't been affected.
There are a lot of reasons for this, but for one, imagine that you executed a script in the background (via ./foo.js &
) and as it ran, it started changing your working directory or overriding your PATH
. That would be a nightmare.
If you need to perform some actions that require changing your working directory of your shell, you'll need to write a function in your shell. For example, if you're running Bash, you could put this in your ~/.bash_profile
:
do_cool_thing() {
cd "/Users"
echo "Hey, I'm in $PWD"
}
and then this cool thing is doable:
$ pwd
/Users/spike
$ do_cool_thing
Hey, I'm in /Users
$ pwd
/Users
If you need to do more complex things in addition, you could always call out to your nodejs script from that function.
This is the only way you can accomplish what you're trying to do.
You can use -webkit-border-radius: 0;
. Like this:-
-webkit-border-radius: 0;
border: 0;
outline: 1px solid grey;
outline-offset: -1px;
This will give square corners as well as dropdown arrows. Using -webkit-appearance: none;
is not recommended as it will turn off all the styling done by Chrome.
You can use the already mentioned built in Responsive Design Mode (via dev tools) for setting customised screen sizes together with the Random Agent Spoofer Plugin to modify your headers to simulate you are using Mobile, Tablet etc. Many websites specify their content according to these identified headers.
As dev tools you can use the built in Developer Tools (Ctrl + Shift + I or Cmd + Shift + I for Mac) which have become quite similar to Chrome dev tools by now.
Update: As of July 2013 this project is no longer maintained. The author suggests using pyenv. (pyenv does not have built-in support for virtualenv, but plays nice with it.)
Pythonbrew is a version manager for python and comes with support for virtualenv.
After installing pythonbrew and a python-version using venvs is really easy:
# Initializes the virtualenv
pythonbrew venv init
# Create a virtual/sandboxed environment
pythonbrew venv create mycoolbundle
# Use it
pythonbrew venv use mycoolbundle
In python 3 T
kinter renamed t
kinter
Your formula should be of the form =IF(X2 >= 85,0.559,IF(X2 >= 80,0.327,IF(X2 >=75,0.255,0)))
. This simulates the ELSE-IF
operand Excel lacks. Your formulas were using two conditions in each, but the second parameter of the IF
formula is the value to use if the condition evaluates to true
. You can't chain conditions in that manner.
The base-class constructor is already automatically called by your derived-class constructor. In C++, if the base class has a default constructor (takes no arguments, can be auto-generated by the compiler!), and the derived-class constructor does not invoke another base-class constructor in its initialisation list, the default constructor will be called. I.e. your code is equivalent to:
class PetStore: public Farm
{
public :
PetStore()
: Farm() // <---- Call base-class constructor in initialision list
{
idF=0;
};
private:
int idF;
string nameF;
}
This exception only happens if you are parsing an empty String/empty byte array.
below is a snippet on how to reproduce it:
String xml = ""; // <-- deliberately an empty string.
ByteArrayInputStream xmlStream = new java.io.ByteArrayInputStream(xml.getBytes());
Unmarshaller u = JAXBContext.newInstance(...)
u.setSchema(...);
u.unmarshal( xmlStream ); // <-- here it will fail

In IIS you can declare the mime type for WOFF2 font files by adding the following to your project's web.config:
<system.webServer>
<staticContent>
<remove fileExtension=".woff2" />
<mimeMap fileExtension=".woff2" mimeType="font/woff2" />
</staticContent>
</system.webServer>
Update:
The mime type may be changing according to the latest W3C Editor's Draft WOFF2 spec. See Appendix A: Internet Media Type Registration section 6.5. WOFF 2.0 which states the latest proposed format is font/woff2
MemoryStream ms = new MemoryStream();
yourBitmap.Save(ms, ImageFormat.Bmp);
byte[] bitmapData = ms.ToArray();
You can use setCompoundDrawablesWithIntrinsicBounds(int left, int top, int right, int bottom)
set 0 where you don't want images
Example for Drawable on the left:
TextView textView = (TextView) findViewById(R.id.myTxtView);
textView.setCompoundDrawablesWithIntrinsicBounds(R.drawable.icon, 0, 0, 0);
Alternatively, you can use setCompoundDrawablesRelativeWithIntrinsicBounds to respect RTL/LTR layouts.
Tip: Whenever you know any XML attribute but don't have clue about how to use it at runtime. just go to the description of that property in developer doc. There you will find Related Methods if it's supported at runtime . i.e. For DrawableLeft
The error you get if because you need to escape the quotes (like other answers said).
To avoid that, you can use an alternative syntax for you strings declarations, called "Heredoc"
With this syntax, you can declare a long string, even containing single-quotes and/or double-quotes, whithout having to escape thoses ; it will make your Javascript code easier to write, modify, and understand -- which is always a good thing.
As an example, your code could become :
$str = <<<MY_MARKER
<script type="text/javascript">
document.write("Hello World!");
</script>
MY_MARKER;
echo $str;
Note that with Heredoc syntax (as with string delimited by double-quotes), variables are interpolated.
You can use CSS Flexbox instead another display value, The Flexbox Layout (Flexible Box) module aims at providing a more efficient way to lay out, align and distribute space among items in a container, even when their size is unknown and/or dynamic.
Example
/* CONTAINER */
#wrapper
{
width:300px;
height:300px;
display: -webkit-box; /* OLD - iOS 6-, Safari 3.1-6 */
display: -moz-box; /* OLD - Firefox 19- (buggy but mostly works) */
display: -ms-flexbox; /* TWEENER - IE 10 */
display: -webkit-flex; /* NEW - Chrome */
display: flex; /* NEW, Spec - Opera 12.1, Firefox 20+ */
-ms-flex-direction: column;
-moz-flex-direction: column;
-webkit-flex-direction: column;
flex-direction: column;
}
/* SOME ITEM CHILD ELEMENTS */
#first
{
width:300px;
height: 200px;
background-color:#F5DEB3;
}
#second
{
width:300px;
background-color: #9ACD32;
-webkit-box-flex: 1; /* OLD - iOS 6-, Safari 3.1-6 */
-moz-box-flex: 1; /* OLD - Firefox 19- */
-webkit-flex: 1; /* Chrome */
-ms-flex: 1; /* IE 10 */
flex: 1; /* NEW, */
}
If you want to have full support for old browsers like IE9 or below, you will have to use a polyfills like flexy, this polyfill enable support for Flexbox model but only for 2012 spec of flexbox model.
Recently I found another polyfill to help you with Internet Explorer 8 & 9 or any older browser that not have support for flexbox model, I still have not tried it but I leave the link here
You can find a usefull and complete Guide to Flexbox model by Chris Coyer here
You don't need an index match formula. You can use this array formula. You have to press CTL + SHIFT + ENTER after you enter the formula.
=MAX(IF((A1:A6=A10)*(B1:B6=B10),C1:F6))
SNAPSHOT
If you still want to specify your colors in your XML file:
<color name="errorColor">#f00</color>
Then reference it in your code with one of these two methods:
textView.setTextColor(getResources().getColor(R.color.errorColor, getResources().newTheme()));
or
textView.setTextColor(getResources().getColor(R.color.errorColor, null));
The first is probably preferable if you're compiling against Android M, however the theme you pass in can be null, so maybe that's easier for you?
And if you're using the Compat library you can do something like this
textView.setTextColor(ContextCompat.getColor(context, R.color.errorColor));
file_get_contents()
usually has permission issues. To avoid them, use:
function get_xml_from_url($url){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13');
$xmlstr = curl_exec($ch);
curl_close($ch);
return $xmlstr;
}
Example:
$xmlstr = get_xml_from_url('http://www.camara.gov.br/SitCamaraWS/Deputados.asmx/ObterDeputados');
$xmlobj = new SimpleXMLElement($xmlstr);
$xmlobj = (array)$xmlobj;//optional
Somewhere, you need to tell Apache that people are allowed to see contents of this directory.
<Directory "F:/bar/public">
Order Allow,Deny
Allow from All
# Any other directory-specific stuff
</Directory>
Adding another version based on example above by @ricky89 and @mklement0 with few improvements:
Script to process:
LF-to-CRLF.ps1:
# get current dir
$currentDirectory = Split-Path $MyInvocation.MyCommand.Path -Parent
# create subdir CR-to-CRLF for new files
$outDir = $(Join-Path $currentDirectory "CR-to-CRLF")
New-Item -ItemType Directory -Force -Path $outDir | Out-Null
# get all .txt files
Get-ChildItem $currentDirectory -Force | Where-Object {$_.extension -eq ".txt"} | ForEach-Object {
$file = New-Object System.IO.StreamReader -Arg $_.FullName
# Resulting file will be in CR-to-CRLF subdir
$outstream = [System.IO.StreamWriter] $(Join-Path $outDir $($_.BaseName + $_.Extension))
$count = 0
# read line by line, replace CR with CRLF in each by saving it with $outstream.WriteLine
while ($line = $file.ReadLine()) {
$count += 1
$outstream.WriteLine($line)
}
$file.close()
$outstream.close()
Write-Host ("$_`: " + $count + ' lines processed.')
}
I think you should understand what delayed expansion is. The existing answers don't explain it (sufficiently) IMHO.
Typing SET /?
explains the thing reasonably well:
Delayed environment variable expansion is useful for getting around the limitations of the current expansion which happens when a line of text is read, not when it is executed. The following example demonstrates the problem with immediate variable expansion:
set VAR=before if "%VAR%" == "before" ( set VAR=after if "%VAR%" == "after" @echo If you see this, it worked )
would never display the message, since the %VAR% in BOTH IF statements is substituted when the first IF statement is read, since it logically includes the body of the IF, which is a compound statement. So the IF inside the compound statement is really comparing "before" with "after" which will never be equal. Similarly, the following example will not work as expected:
set LIST= for %i in (*) do set LIST=%LIST% %i echo %LIST%
in that it will NOT build up a list of files in the current directory, but instead will just set the LIST variable to the last file found. Again, this is because the %LIST% is expanded just once when the FOR statement is read, and at that time the LIST variable is empty. So the actual FOR loop we are executing is:
for %i in (*) do set LIST= %i
which just keeps setting LIST to the last file found.
Delayed environment variable expansion allows you to use a different character (the exclamation mark) to expand environment variables at execution time. If delayed variable expansion is enabled, the above examples could be written as follows to work as intended:
set VAR=before if "%VAR%" == "before" ( set VAR=after if "!VAR!" == "after" @echo If you see this, it worked ) set LIST= for %i in (*) do set LIST=!LIST! %i echo %LIST%
Another example is this batch file:
@echo off
setlocal enabledelayedexpansion
set b=z1
for %%a in (x1 y1) do (
set b=%%a
echo !b:1=2!
)
This prints x2
and y2
: every 1 gets replaced by a 2.
Without setlocal enabledelayedexpansion
, exclamation marks are just that, so it will echo !b:1=2!
twice.
Because normal environment variables are expanded when a (block) statement is read, expanding %b:1=2%
uses the value b
has before the loop: z2
(but y2
when not set).
Yes, you will have to implement the constructors that make sense for each derivation and then use the base
keyword to direct that constructor to the appropriate base class or the this
keyword to direct a constructor to another constructor in the same class.
If the compiler made assumptions about inheriting constructors, we wouldn't be able to properly determine how our objects were instantiated. In the most part, you should consider why you have so many constructors and consider reducing them to only one or two in the base class. The derived classes can then mask out some of them using constant values like null
and only expose the necessary ones through their constructors.
In C#4 you could specify default parameter values and use named parameters to make a single constructor support multiple argument configurations rather than having one constructor per configuration.
select persons.personsid,name,info.id,address
-> from persons
-> inner join persons on info.infoid = info.info.id;
I invite you to try out BoneCP -- it's free, open source, and faster than the available alternatives (see benchmark section).
Disclaimer: I'm the author so you could say I'm biased :-)
UPDATE: As of March 2010, still around 35% faster than the new rewritten Apache DBCP ("tomcat jdbc") pool. See dynamic benchmark link in benchmark section.
Update #2: (Dec '13) After 4 years at the top, there's now a much faster competitor : https://github.com/brettwooldridge/HikariCP
Update #3: (Sep '14) Please consider BoneCP to be deprecated at this point, recommend switching to HikariCP.
Update #4: (April '15) -- I no longer own the domain jolbox.com
I had a similar problem with gitlab. It turns out I had restricted the users that are allowed to login via ssh. This won't affect github users, but in case people end up here for gitlab (and the like) issues, ensure you add git
to the AllowUsers
setting in /etc/ssh/sshd_config
:
# Authentication:
LoginGraceTime 120
PermitRootLogin no
StrictModes yes

//closure for "on" statement
function ($join) {
$join->on('users.id', '=', 'comments_by_user.user_id');

Just cast one to int and then cast it to the other enum (considering that you want the mapping done based on value):
Gender2 gender2 = (Gender2)((int)gender1);
I hope this could be helpful for whom has similar problem .
In ObjectExplorer
window, select your database=> Tables,=> your table=> Constraints. If the customer is defined on create column time, you can see the default name of constraint including the column name.
then use:
ALTER TABLE yourTableName DROP CONSTRAINT DF__YourTa__NewCo__47127295;
(the constraint name is just an example)
What solved it for me was using :
regasm.exe 'xx.dll' /tlb /codebase /register
It is however, important to understand the difference between regasm.exe and regsvr.exe:
What is difference between RegAsm.exe and regsvr32? How to generate a tlb file using regsvr32?
Old question, but apparently Google likes it so I thought I put an answer down here after some research about this problem.
If you create a figure from scratch you can give it a size option while creation:
import matplotlib.pyplot as plt
fig = plt.figure(figsize=(3, 6))
plt.plot(range(10)) #plot example
plt.show() #for control
fig.savefig('temp.png', dpi=fig.dpi)
figsize(width,height) adjusts the absolute dimension of your plot and helps to make sure both plots look the same.
As stated in another answer the dpi option affects the relative size of the text and width of the stroke on lines, etc. Using the option dpi=fig.dpi makes sure the relative size of those are the same both for show() and savefig().
Alternatively the figure size can be changed after creation with:
fig.set_size_inches(3, 6, forward=True)
forward allows to change the size on the fly.
If you have trouble with too large borders in the created image you can adjust those either with:
plt.tight_layout()
#or:
plt.tight_layout(pad=2)
or:
fig.savefig('temp.png', dpi=fig.dpi, bbox_inches='tight')
#or:
fig.savefig('temp.png', dpi=fig.dpi, bbox_inches='tight', pad_inches=0.5)
The first option just minimizes the layout and borders and the second option allows to manually adjust the borders a bit. These tips helped at least me to solve my problem of different savefig() and show() images.
I think the best approach is to use OAuth2. Google it and you will find a lot of useful posts to help you set it up.
It will make easier to develop client applications for your API from a web app or a mobile one.
Hope it helps you.
The best way to do it now is:

use now() in any cell. then use that cell as a "dummy" parameter in a function. when now() changes every minute the formula recalculates. example: someFunction(a1,b1,c1) * (cell with now() / cell with now())
Yes.
I use uncompyle6 decompile (even support latest Python 3.8.0):
uncompyle6 utils.cpython-38.pyc > utils.py
and the origin python and decompiled python comparing look like this:
so you can see, ALMOST same, decompile effect is VERY GOOD.

Follow the instruction from RishiKesh Pathak above, you can even short the push command by inserting this command line one time only:
git config --global push.default simple
So next time instead of using git push origin master
you just need:
git push
See details here.
Ran into something like this recently - for future reference
import chardet
encoding = chardet.detect(string)
if encoding['encoding'] == 'ascii':
print 'string is in ascii'
which you could use with:
string_ascii = string.decode(encoding['encoding']).encode('ascii')
var value = CKEDITOR.instances['YourInstanceName'].getData()
alert( value);
Replace YourInstanceName
with the name of your instance and you will get the desired results.

To finish the set off (with what has already been suggested):
SELECT * FROM sys.views
This gives extra properties on each view, not available from sys.objects (which contains properties common to all types of object) or INFORMATION_SCHEMA.VIEWS. Though INFORMATION_SCHEMA approach does provide the view definition out-of-the-box.
almost there, just change outerWidth: 100%;
to width: auto;
(outerWidth is not a CSS property)
alternatively, apply the following styles to bar:
width: auto;
display: block;
It looks like the latest version of anaconda forces install of pyqt5.6 over any pyqt build, which will be fatal for your applications. In a terminal, Try:
conda install -c anaconda pyqt=4.11.4
It will prompt to downgrade conda client. After that, it should be good.
UPDATE: If you want to know what pyqt versions are available for install, try:
conda search pyqt
UPDATE: The most recent version of conda installs anaconda-navigator. This depends on qt5, and should first be removed:
conda uninstall anaconda-navigator
Then install "newest" qt4:
conda install qt=4
Not an official answer by any means (just a guess based on using the language), but Python allows you to use lists as stacks (e.g., section 5.1.1 of the tutorial). However, a list is still first of all a list, so the operations that are common to both use list terms (i.e., append) rather than stack terms (i.e., push). Since a pop operation isn't that common in lists (though 'removeLast' could have been used), they defined a pop() but not a push().
Real VNC Viewer (5.0.3) - Free :

It can, because a
is a variable allocated temporarily for the lifetime of its scope (foo
function). After you return from foo
the memory is free and can be overwritten.
What you're doing is described as undefined behavior. The result cannot be predicted.
In the following line.
temp.Response = db.Responses.Where(y => y.ResponseId.Equals(item.ResponseId)).First();
You are calling First but the collection returned from db.Responses.Where is empty.
var data = JSON.stringify
({
'StrContactDetails': Details,
'IsPrimary': true
})
Use it like this, should work:
<a routerLink="/Service/Sign_in"><button class="btn btn-success pull-right" > Add Customer</button></a>
You can also use router.navigateByUrl('..')
like this:
<button type="button" class="btn btn-primary-outline pull-right" (click)="btnClick();"><i class="fa fa-plus"></i> Add</button>
import { Router } from '@angular/router';
btnClick= function () {
this.router.navigateByUrl('/user');
};
You have to inject Router
in the constructor like this:
constructor(private router: Router) { }
only then you are able to use this.router
. Remember also to import RouterModule
in your module.
Now, After Angular v4 you can directly add routerLink
attribute on the button (As mentioned by @mark in comment section) like below (No "'/url?" since Angular 6, when a Route in RouterModule exists) -
<button [routerLink]="'url'"> Button Label</button>
UIButton *custombutton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[custombutton addTarget:self
action:@selector(aMethod:)
forControlEvents:UIControlEventTouchUpInside];
[custombutton setTitle:@"Click" forState:UIControlStateNormal];
custombutton.frame = CGRectMake(80.0, 110.0, 160.0, 40.0);
custombutton.titleLabel.textColor = [UIColor colorWithRed: 2.0f/255.0f green: 155.0f/255.0f blue: 213.0f/255.0f alpha:1];
[custombutton setImage:[UIImage imageNamed:@"hh.png"] forState:UIControlStateNormal];
[view addSubview:custombutton];
The best way I found is using keydown
( the keyup
doesn't work well for me).
Note: I also disabled the form submit because usually when you like to do some actions when pressing Enter Key the only think you do not like is to submit the form :)
$('input').keydown( function( event ) {
if ( event.which === 13 ) {
// Do something
// Disable sending the related form
event.preventDefault();
return false;
}
});
If you are using auto-generated Mongo Object Ids in your document, it contains timestamp in it as first 4 bytes using which latest doc inserted into the collection could be found out. I understand this is an old question, but if someone is still ending up here looking for one more alternative.
db.collectionName.aggregate(
[{$group: {_id: null, latestDocId: { $max: "$_id"}}}, {$project: {_id: 0, latestDocId: 1}}])
Above query would give the _id for the latest doc inserted into the collection
Unless I misunderstand your question, you can just open a file read only. Here is a simply example, without any checks.
To get the file path from the user use this function:
Private Function get_user_specified_filepath() As String
'or use the other code example here.
Dim fd As Office.FileDialog
Set fd = Application.FileDialog(msoFileDialogFilePicker)
fd.AllowMultiSelect = False
fd.Title = "Please select the file."
get_user_specified_filepath = fd.SelectedItems(1)
End Function
Then just open the file read only and assign it to a variable:
dim wb as workbook
set wb = Workbooks.Open(get_user_specified_filepath(), ReadOnly:=True)
First open a console then cd to where you've downloaded your file like some-package.whl and use
pip install some-package.whl
Note: if pip.exe is not recognized, you may find it in the "Scripts" directory from where python has been installed. I have multiple Python installations, and needed to use the pip associated with Python 3 to install a version 3 wheel.

I have a Range
class in MiscUtil which you could find useful. Combined with the various extension methods, you could do:
foreach (DateTime date in StartDate.To(EndDate).ExcludeEnd()
.Step(DayInterval.Days())
{
// Do something with the date
}
(You may or may not want to exclude the end - I just thought I'd provide it as an example.)
This is basically a ready-rolled (and more general-purpose) form of mquander's solution.
The only way I able to get this to work was by doing this on the presenting view controller:
func didTapButton() {
self.definesPresentationContext = true
self.modalTransitionStyle = .crossDissolve
let yourVC = self.storyboard?.instantiateViewController(withIdentifier: "YourViewController") as! YourViewController
let navController = UINavigationController(rootViewController: yourVC)
navController.modalPresentationStyle = .overCurrentContext
navController.modalTransitionStyle = .crossDissolve
self.present(navController, animated: true, completion: nil)
}
Just to clear some things up here. The answer that was accepted does not do the same as PHP in_array.
To do the same as PHP in_array use following expression:
{% if myVar in myArray %}
If you want to negate this you should use this:
{% if myVar not in myArray %}
The VH
unit can be used to fill the background of the viewport, aka the browser window.

html{

.body {
background: url(image.jpg) no-repeat center top;
background-size: cover;
height:100vh;

I simplified Lasnv's answer a bit.
It also fixes the bug that WebDeb describes.
Here it is:
var regExp = /^.*(youtu\.be\/|v\/|u\/\w\/|embed\/|watch\?v=|\&v=)([^#\&\?]*).*/;
var match = url.match(regExp);
if (match && match[2].length == 11) {
return match[2];
} else {
//error
}
Here is a regexer link to play with: http://regexr.com/3dnqv
Try following these steps:
You can not run/execute an .exe file that is in the users local machine or through a site. The user must first download the exe file and then run the executable file.
So there is no possible way
The following code works only when the EXE is Present in the User's Machine.
<a href = "C:\folder_name\program.exe">
Try any of these
RENAME TABLE `group` TO `member`;
or
ALTER TABLE `group` RENAME `member`;

As we see from the javaDoc, BigInteger
is not a subclass of Integer
:
java.lang.Object java.lang.Object
java.lang.Number java.lang.Number
java.math.BigInteger java.lang.Integer
And that's the reason why casting from BigInteger
to Integer
is impossible.
Casting of java primitives will do some conversion (like casting from double
to int
) while casting of types will never transform classes.
Assuming you want to do it yourself and not rely upon other providers, IP2Nation provides a MySQL database of the mappings which are updated as the regional registries change things around.

The best way to solve this problem "X-CSRF-TOKEN" is to add the following code to your main layout, and continue making your ajax calls normally:
In header
<meta name="csrf-token" content="{{ csrf_token() }}" />
In script
<script type="text/javascript">
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
</script>
If you need the functionality if a index for a column exists (here at first place in sequence) as a database function you can use/adopt this code. If you want to check if an index exists at all regardless of the position in a multi-column-index, then just delete the part "AND SEQ_IN_INDEX = 1".

you can use concat([df1, df2, ...], axis=1) in order to concatenate two or more DFs aligned by indexes:
pd.concat([df1, df2, df3, ...], axis=1)
or merge for concatenating by custom fields / indexes:
# join by _common_ columns: `col1`, `col3`
pd.merge(df1, df2, on=['col1','col3'])
# join by: `df1.col1 == df2.index`
pd.merge(df1, df2, left_on='col1' right_index=True)
or join for joining by index:
df1.join(df2)

Flag operators on integral type just works.
Better approach may be a polyfill like this
jQuery.fn.load = function(callback){ $(window).on("load", callback) };
With this you can leave the legacy code untouched. If you use webpack be sure to use script-loader.
First step would be making the function object, then applying it. If you want a matrix object that has the same number of rows, you can predefine it and use the object[] form as illustrated (otherwise the returned value will be simplified to a vector):
bvnormdens <- function(x=c(0,0),mu=c(0,0), sigma=c(1,1), rho=0){
exp(-1/(2*(1-rho^2))*(x[1]^2/sigma[1]^2+
x[2]^2/sigma[2]^2-
2*rho*x[1]*x[2]/(sigma[1]*sigma[2]))) *
1/(2*pi*sigma[1]*sigma[2]*sqrt(1-rho^2))
}
out=rbind(c(1,2),c(3,4),c(5,6));
bvout<-matrix(NA, ncol=1, nrow=3)
bvout[] <-apply(out, 1, bvnormdens)
bvout
[,1]
[1,] 1.306423e-02
[2,] 5.931153e-07
[3,] 9.033134e-15
If you wanted to use other than your default parameters then the call should include named arguments after the function:
bvout[] <-apply(out, 1, FUN=bvnormdens, mu=c(-1,1), rho=0.6)
apply() can also be used on higher dimensional arrays and the MARGIN argument can be a vector as well as a single integer.
You can enable NuGet packages and update you dlls. so that it work. or you can update the package manually by going through the package manager in your vs if u know which version you require for your solution.
If you want to get rid of the extra xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
and xmlns:xsd="http://www.w3.org/2001/XMLSchema"
, but still keep your own namespace xmlns="http://schemas.YourCompany.com/YourSchema/"
, you use the same code as above except for this simple change:
// Add lib namespace with empty prefix
ns.Add("", "http://schemas.YourCompany.com/YourSchema/");
I think what you are looking for is:
startDate.setDate(startDate.getDate() + 1);
Also, you can have a look at Moment.js
A javascript date library for parsing, validating, manipulating, and formatting dates.
Just do what the message is asking for, create the user pma@localhost in the phpMyAdmin panel with no password
Create a stored procedure that does something like the following:
declare @startDate date;
declare @endDate date;
select @startDate = '20150528';
select @endDate = '20150531';
with dateRange as
(
select dt = dateadd(dd, 1, @startDate)
where dateadd(dd, 1, @startDate) < @endDate
union all
select dateadd(dd, 1, dt)
from dateRange
where dateadd(dd, 1, dt) < @endDate
)
select *
from dateRange
Or better still create a calendar table and just select from that.
In Access 2013 I've just tested this:
While ComboBox1.ListCount > 0

Interestingly, if you set the item list in Properties, this is not lost when you exit Form View and go back to Design View.
My experience:
var text = $('#myInputField');
var myObj = {title: 'Some title', content: text};
$.post(myUrl, myObj, callback);
The problem is that I forgot to add .val() to the end of $('#myInputField'); this action makes me waste time trying to figure out what was wrong, causing Illegal Invocation Error, since $('#myInputField') was in a different file than that system pointed out incorrect code. Hope this answer help fellows in the same mistake to avoid to loose time.
If you want to pass a pointer-to-int into your function,
Declaration of function (if you need it):
void Fun(int *ptr);
Definition of function:
void Fun(int *ptr) {
int *other_pointer = ptr; // other_pointer points to the same thing as ptr
*other_ptr = 3; // manipulate the thing they both point to
}
Use of function:
int main() {
int x = 2;
printf("%d\n", x);
Fun(&x);
printf("%d\n", x);
}
Note as a general rule, that variables called Ptr
or Pointer
should never have type int
, which is what you have then in your code. A pointer-to-int has type int *
.
If I have a second pointer (int *oof), then:
bar = oof means: bar points to the oof pointer
It means "make bar point to the same thing oof points to".
bar = *oof means: bar points to the value that oof points to, but not to the oof pointer itself
That doesn't mean anything, it's invalid. bar
is a pointer *oof
is an int. You can't assign one to the other.
*bar = *oof means: change the value that bar points to to the value that oof points to
Yes.
&bar = &oof means: change the memory address that bar points to be the same as the memory address that oof points to
Nope, that's invalid again. &bar
is a pointer to the bar
variable, but it is what's called an "rvalue", or "temporary", and it cannot be assigned to. It's like the result of an arithmetic calculation. You can't write x + 1 = 5
.
It might help you to think of pointers as addresses. bar = oof
means "make bar, which is an address, equal to oof, which is also an address". bar = &foo
means "make bar, which is an address, equal to the address of foo". If bar = *oof
meant anything, it would mean "make bar, which is an address, equal to *oof
, which is an int". You can't.
Then, &
is the address-of operator. It means "the address of the operand", so &foo
is the address of foo (i.e, a pointer to foo). *
is the dereference operator. It means "the thing at the address given by the operand". So having done bar = &foo
, *bar
is foo
.
ASCII is in range of 0 to 127, so:
str.replace(/[^\x00-\x7F]/g, "");
I used following logic and it worked for me like marvel:
CONVERT(TIME, DATEADD(MINUTE, DATEDIFF(MINUTE, AP.Time_IN, AP.Time_OUT), 0))
If you want "To get all tables only", Then use this query:
SELECT TABLE_NAME
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_NAME like '%'
and TABLE_SCHEMA = 'tresbu_lk'
If you want "To get all tables with Columns", Then use this query:
SELECT DISTINCT TABLE_NAME, COLUMN_NAME
FROM INFORMATION_SCHEMA.COLUMNS
WHERE column_name LIKE '%'
AND TABLE_SCHEMA='tresbu_lk'

I have the same issue with the ".index()" method on lists. I have no issue with the fact that it throws an exception but I strongly disagree with the fact that it's a non-descriptive ValueError. I could understand if it would've been an IndexError, though.
I can see why returning "-1" would be an issue too because it's a valid index in Python. But realistically, I never expect a ".index()" method to return a negative number.
Here goes a one liner (ok, it's a rather long line ...), goes through the list exactly once and returns "None" if the item isn't found. It would be trivial to rewrite it to return -1, should you so desire.
indexOf = lambda list, thing: \
reduce(lambda acc, (idx, elem): \
idx if (acc is None) and elem == thing else acc, list, None)
How to use:
>>> indexOf([1,2,3], 4)
>>>
>>> indexOf([1,2,3], 1)
0
>>>
I had an inversion problem, but a neat solution.
Motivation was that the XAML designer would show an empty control e.g. when there was no datacontext / no MyValues
(itemssource).
Initial code: hide control when MyValues
is empty.
Improved code: show control when MyValues
is NOT null or empty.
Ofcourse the problem is how to express '1 or more items', which is the opposite of 0 items.
<ListBox ItemsSource={Binding MyValues}">
<ListBox.Style x:Uid="F404D7B2-B7D3-11E7-A5A7-97680265A416">
<Style TargetType="{x:Type ListBox}">
<Style.Triggers>
<DataTrigger Binding="{Binding MyValues.Count}">
<Setter Property="Visibility" Value="Collapsed"/>
</DataTrigger>
</Style.Triggers>
</Style>
</ListBox.Style>
</ListBox>
I solved it by adding:
<DataTrigger Binding="{Binding MyValues.Count, FallbackValue=0, TargetNullValue=0}">
Ergo setting the default for the binding. Ofcourse this doesn't work for all kinds of inverse problems, but helped me out with clean code.
Check this:
hello.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View paramView) {
text.setText("hello");
}
});
Close: first you call ExcelFile
, but then you call the .parse
method and pass it the sheet name.
>>> xl = pd.ExcelFile("dummydata.xlsx")
>>> xl.sheet_names
[u'Sheet1', u'Sheet2', u'Sheet3']
>>> df = xl.parse("Sheet1")
>>> df.head()

4 0.595100 0 6.350000 3.974442
What you're doing is calling the method which lives on the class itself, rather than the instance, which is okay (although not very idiomatic), but if you're doing that you would also need to pass the sheet name:
>>> parsed = pd.io.parsers.ExcelFile.parse(xl, "Sheet1")
>>> parsed.columns
Index([u'Tid', u'dummy1', u'dummy2', u'dummy3', u'dummy4', u'dummy5', u'dummy6', u'dummy7', u'dummy8', u'dummy9'], dtype=object)
Like you say, os.path.join
joins paths based on the current os. posixpath
is the underlying module that is used on posix systems under the namespace os.path
:
>>> os.path.join is posixpath.join
True
>>> posixpath.join('/media/', 'js/foo.js')
'/media/js/foo.js'
So you can just import and use posixpath.join
instead for urls, which is available and will work on any platform.
Edit: @Pete's suggestion is a good one, you can alias the import for increased readability
from posixpath import join as urljoin
Edit: I think this is made clearer, or at least helped me understand, if you look into the source of os.py
(the code here is from Python 2.7.11, plus I've trimmed some bits). There's conditional imports in os.py
that picks which path module to use in the namespace os.path
. All the underlying modules (posixpath
, ntpath
, os2emxpath
, riscospath
) that may be imported in os.py
, aliased as path
, are there and exist to be used on all systems. os.py
is just picking one of the modules to use in the namespace os.path
at run time based on the current OS.
# os.py
import sys, errno
_names = sys.builtin_module_names
if 'posix' in _names:
# ...

Sometimes two classes may have some parameter names in common. In that case, you can't pop the key-value pairs off of **kwargs
or remove them from *args
. Instead, you can define a Base
class which unlike object
, absorbs/ignores arguments:
class Base(object):
def __init__(self, *args, **kwargs): pass
class A(Base):
def __init__(self, *args, **kwargs):
print "A"
super(A, self).__init__(*args, **kwargs)
class B(Base):
def __init__(self, *args, **kwargs):
print "B"
super(B, self).__init__(*args, **kwargs)
class C(A):
def __init__(self, arg, *args, **kwargs):
print "C","arg=",arg
super(C, self).__init__(arg, *args, **kwargs)
class D(B):
def __init__(self, arg, *args, **kwargs):
print "D", "arg=",arg
super(D, self).__init__(arg, *args, **kwargs)
class E(C,D):
def __init__(self, arg, *args, **kwargs):
print "E", "arg=",arg
super(E, self).__init__(arg, *args, **kwargs)
print "MRO:", [x.__name__ for x in E.__mro__]
E(10)
yields
MRO: ['E', 'C', 'A', 'D', 'B', 'Base', 'object']
E arg= 10
C arg= 10
A
D arg= 10
B
Note that for this to work, Base
must be the penultimate class in the MRO.
What I know is one reason when “GC overhead limit exceeded” error is thrown when 2% of the memory is freed after several GC cycles
By this error your JVM is signalling that your application is spending too much time in garbage collection. so the little amount GC was able to clean will be quickly filled again thus forcing GC to restart the cleaning process again.
You should try changing the value of -Xmx
and -Xms
.
If you don't need the leading and trailing spaces :
str.Trim().Length
You could encapsulate the string in a struct that implements IFormattable
public struct PaddedString : IFormattable
{
private string value;
public PaddedString(string value) { this.value = value; }
public string ToString(string format, IFormatProvider formatProvider)
{
//... use the format to pad value
}
public static explicit operator PaddedString(string value)
{
return new PaddedString(value);
}
}
Then use this like that :
string.Format("->{0:x20}<-", (PaddedString)"Hello");
result:
"->xxxxxxxxxxxxxxxHello<-"
problem is that the collapse item (div) is nested in the table elements. The div is hidden, the tr and td of the table are still visible and some css-styles are applied to them (border and padding).
Why are you using tables? Is there a reason for? When you dont´t have to use them, dont´use them :-)
After installation, you need the following configuration to properly send mail from wampserver:
1) When you first open hMailServer Administrator, you need to add a new domain.
2) Click on the "Add Domain ..." button at the Welcome page.
3) Under the domain text field, enter your computer's IP, in this case it should be 127.0.0.1.
4) Click on the Save button.
5) Go to Settings>Protocols>SMTP and select "Delivery of Email" tab
6) Enter "localhost" in the localhost name field.
7) Click on the Save button.
If you need to send mail using a FROM addressee of another computer, you need to allow deliveries from External to External accounts. To do that, follow these steps:
1) Go to Settings>Advanced>IP Ranges and double click on "My Computer" which should have IP address of 127.0.0.1
2) Check the Allow Deliveries from External to External accounts checkbox.
3) Save settings using Save button.
(However, Windows Live/Hotmail has denied all emails coming from dynamic IPs, which most residential computers are using. The workaround is to use Gmail account )
1) Go to Settings>Protocols>SMTP and select "Delivery of Email" tab
2) Enter "smtp.gmail.com" in the Remote Host name field.
3) Enter "465" as the port number
4) Check "Server requires authentication"
5) Enter gmail address in the Username
6) Enter gmail password in the password
7) Check "Use SSL"
(Note, From field doesnt function with gmail)
*p.s. For some people it might also be needed to untick everything under require SMTP authentication
in :
You can use SendMail installation.
Use any of these methods.
If you have names of the element and not id we can achieve the undefined check on all text elements (for example) as below and fill them with a default value say 0.0:
var aFieldsCannotBeNull=['ast_chkacc_bwr','ast_savacc_bwr'];
jQuery.each(aFieldsCannotBeNull,function(nShowIndex,sShowKey) {
var $_oField = jQuery("input[name='"+sShowKey+"']");
if($_oField.val().trim().length === 0){
$_oField.val('0.0')
}
})
using pip:
pip install mechanize
or download the mechanize distribution archive, open it, and run:
python setup.py install
Another option is to split off the textarea in the Site.css as follows:
/* Set width on the form input elements since they're 100% wide by default */
input,
select {
max-width: 280px;
}
textarea {
/*max-width: 280px;*/
max-width: 500px;
width: 280px;
height: 200px;
}
also (in my MVC 5) add ref to textarea:
@Html.TextAreaFor(model => ................... @class = "form-control", @id="textarea"............
It worked for me
If you need to manually read a properties file without using @Value.

If you rotate bitmap, 90 180 270 360 is ok but for other degrees canvas will draw bitmap with different size.
So,the best way is
canvas.rotate(degree,rotateCenterPoint.x,rotateCenterPoint.y);
canvas.drawBitmap(...);

DOUBLE(10) precision definitions need a total number of digits, as well as a total number of digits after the decimal:
DOUBLE(10,8) would make be ten total digits, with 8 allowed after the decimal.
Also, you'll need to specify your id column as a key :
CREATE TABLE transactions(
id int NOT NULL AUTO_INCREMENT,
location varchar(50) NOT NULL,
description varchar(50) NOT NULL,
category varchar(50) NOT NULL,
amount double(10,9) NOT NULL,
type varchar(6) NOT NULL,
notes varchar(512),
receipt int(10),
PRIMARY KEY(id) );
I got the answer to my own question, ant this is:
select reverse(stuff(reverse('a,b,c,d,'), 1, N, ''))
Where N is the number of characters to remove. This avoids to write the complex column/string twice

Programmers from structural programming language background know it as a function while in OOPS it's called a method.
But there's not any difference between the two.
In the old days, methods did not return values and functions did. Now they both are used interchangeably.
This syntax worked for me in MVC 3 with Razor:
@Html.ActionLink("Delete", "DeleteList", "List", new { ID = item.ID, ListID = item.id }, new {@class= "delete"})
With <button>
, you can use img tags, etc. where text is
<button type='submit'> text -- can be img etc. </button>
with <input>
type, you are limited to text
I just posted a simple solution that takes 5 seconds here on a related post here - Facebook debugger: Clear whole site cache
short answer... change your permalinks on a worpdress site in the permalinks settings to a custom one. I just added an underscore.
/_%postname%/
then facebook scrapes them all as new urls, new posts.
You will need to convert your response
to json
before you can access response.body
From the docs
fetch(url)
.then(response => response.json())
.then(json => {
console.log('parsed json', json) // access json.body here
})

I had the exact same issue and i just needed to set the SDK for the library project of the MapsApiV2 to Android 2.3.3 (API lvl 10)
Few ideas, in my opinion only first one gives some guarantee:
Keep your secrets on some server on internet, and when needed just grab them and use. If user is about to use dropbox then nothing stops you from making request to your site and get your secret key.
Put your secrets in jni code, add some variable code to make your libraries bigger and more difficult to decompile. You might also split key string in few parts and keep them in various places.
use obfuscator, also put in code hashed secret and later on unhash it when needed to use.
Put your secret key as last pixels of one of your image in assets. Then when needed read it in your code. Obfuscating your code should help hide code that will read it.

This answer simply handle the case of direct parent-child relationship. When parent and child have potentially a lot of intermediaries, check this answer.
While they still work fine, other answers are missing something very important.
Is there not a simple way to pass a child's props to its parent using events, in React.js?
The parent already has that child prop!: if the child has a prop, then it is because its parent provided that prop to the child! Why do you want the child to pass back the prop to the parent, while the parent obviously already has that prop?
Child: it really does not have to be more complicated than that.
var Child = React.createClass({
render: function () {
return <button onClick={this.props.onClick}>{this.props.text}</button>;
},
});
Parent with single child: using the value it passes to the child
var Parent = React.createClass({
getInitialState: function() {
return {childText: "Click me! (parent prop)"};
},
render: function () {
return (
<Child onClick={this.handleChildClick} text={this.state.childText}/>
);
},
handleChildClick: function(event) {
// You can access the prop you pass to the children
// because you already have it!
// Here you have it in state but it could also be
// in props, coming from another parent.
alert("The Child button text is: " + this.state.childText);
// You can also access the target of the click here
// if you want to do some magic stuff
alert("The Child HTML is: " + event.target.outerHTML);
}
});
Parent with list of children: you still have everything you need on the parent and don't need to make the child more complicated.
var Parent = React.createClass({
getInitialState: function() {
return {childrenData: [
{childText: "Click me 1!", childNumber: 1},
{childText: "Click me 2!", childNumber: 2}
]};
},
render: function () {
var children = this.state.childrenData.map(function(childData,childIndex) {
return <Child onClick={this.handleChildClick.bind(null,childData)} text={childData.childText}/>;
}.bind(this));
return <div>{children}</div>;
},
handleChildClick: function(childData,event) {
alert("The Child button data is: " + childData.childText + " - " + childData.childNumber);
alert("The Child HTML is: " + event.target.outerHTML);
}
});
It is also possible to use this.handleChildClick.bind(null,childIndex)
and then use this.state.childrenData[childIndex]
Note we are binding with a null
context because otherwise React issues a warning related to its autobinding system. Using null means you don't want to change the function context. See also.
This is for me a bad idea in term of coupling and encapsulation:
var Parent = React.createClass({
handleClick: function(childComponent) {
// using childComponent.props
// using childComponent.refs.button
// or anything else using childComponent
},
render: function() {
<Child onClick={this.handleClick} />
}
});
Using props: As I explained above, you already have the props in the parent so it's useless to pass the whole child component to access props.
Using refs: You already have the click target in the event, and in most case this is enough. Additionnally, you could have used a ref directly on the child:
<Child ref="theChild" .../>
And access the DOM node in the parent with
React.findDOMNode(this.refs.theChild)
For more advanced cases where you want to access multiple refs of the child in the parent, the child could pass all the dom nodes directly in the callback.
The component has an interface (props) and the parent should not assume anything about the inner working of the child, including its inner DOM structure or which DOM nodes it declares refs for. A parent using a ref of a child means that you tightly couple the 2 components.
To illustrate the issue, I'll take this quote about the Shadow DOM, that is used inside browsers to render things like sliders, scrollbars, video players...:
They created a boundary between what you, the Web developer can reach and what’s considered implementation details, thus inaccessible to you. The browser however, can traipse across this boundary at will. With this boundary in place, they were able to build all HTML elements using the same good-old Web technologies, out of the divs and spans just like you would.
The problem is that if you let the child implementation details leak into the parent, you make it very hard to refactor the child without affecting the parent. This means as a library author (or as a browser editor with Shadow DOM) this is very dangerous because you let the client access too much, making it very hard to upgrade code without breaking retrocompatibility.
If Chrome had implemented its scrollbar letting the client access the inner dom nodes of that scrollbar, this means that the client may have the possibility to simply break that scrollbar, and that apps would break more easily when Chrome perform its auto-update after refactoring the scrollbar... Instead, they only give access to some safe things like customizing some parts of the scrollbar with CSS.
About using anything else
Passing the whole component in the callback is dangerous and may lead novice developers to do very weird things like calling childComponent.setState(...)
or childComponent.forceUpdate()
, or assigning it new variables, inside the parent, making the whole app much harder to reason about.
Edit: ES6 examples
As many people now use ES6, here are the same examples for ES6 syntax
The child can be very simple:
const Child = ({
onClick,
text
}) => (
<button onClick={onClick}>
{text}
</button>
)
The parent can be either a class (and it can eventually manage the state itself, but I'm passing it as props here:
class Parent1 extends React.Component {
handleChildClick(childData,event) {
alert("The Child button data is: " + childData.childText + " - " + childData.childNumber);
alert("The Child HTML is: " + event.target.outerHTML);
}
render() {
return (
<div>
{this.props.childrenData.map(child => (
<Child
key={child.childNumber}
text={child.childText}
onClick={e => this.handleChildClick(child,e)}
/>
))}
</div>
);
}
}
But it can also be simplified if it does not need to manage state:
const Parent2 = ({childrenData}) => (
<div>
{childrenData.map(child => (
<Child
key={child.childNumber}
text={child.childText}
onClick={e => {
alert("The Child button data is: " + child.childText + " - " + child.childNumber);
alert("The Child HTML is: " + e.target.outerHTML);
}}
/>
))}
</div>
)
PERF WARNING (apply to ES5/ES6): if you are using PureComponent
or shouldComponentUpdate
, the above implementations will not be optimized by default because using onClick={e => doSomething()}
, or binding directly during the render phase, because it will create a new function everytime the parent renders. If this is a perf bottleneck in your app, you can pass the data to the children, and reinject it inside "stable" callback (set on the parent class, and binded to this
in class constructor) so that PureComponent
optimization can kick in, or you can implement your own shouldComponentUpdate
and ignore the callback in the props comparison check.
You can also use Recompose library, which provide higher order components to achieve fine-tuned optimisations:
// A component that is expensive to render
const ExpensiveComponent = ({ propA, propB }) => {...}
// Optimized version of same component, using shallow comparison of props
// Same effect as React's PureRenderMixin
const OptimizedComponent = pure(ExpensiveComponent)
// Even more optimized: only updates if specific prop keys have changed
const HyperOptimizedComponent = onlyUpdateForKeys(['propA', 'propB'])(ExpensiveComponent)
In this case you could optimize the Child component by using:
const OptimizedChild = onlyUpdateForKeys(['text'])(Child)
Proxies are classes that are created and loaded at runtime. There is no source code for these classes. I know that you are wondering how you can make them do something if there is no code for them. The answer is that when you create them, you specify an object that implements InvocationHandler
, which defines a method that is invoked when a proxy method is invoked.
You create them by using the call
Proxy.newProxyInstance(classLoader, interfaces, invocationHandler)
The arguments are:
classLoader
. Once the class is generated, it is loaded with this class loader.interfaces
. An array of class objects that must all be interfaces. The resulting proxy implements all of these interfaces.invocationHandler
. This is how your proxy knows what to do when a method is invoked. It is an object that implements InvocationHandler
. When a method from any of the supported interfaces, or hashCode
, equals
, or toString
, is invoked, the method invoke
is invoked on the handler, passing the Method
object for the method to be invoked and the arguments passed.For more on this, see the documentation for the Proxy
class.
Every implementation of a JVM after version 1.3 must support these. They are loaded into the internal data structures of the JVM in an implementation-specific way, but it is guaranteed to work.
if you put the alter into a transaction the table should not be locked:
BEGIN;
ALTER TABLE "public"."mytable" ALTER COLUMN "mycolumn" TYPE varchar(40);
COMMIT;
this worked for me blazing fast, few seconds on a table with more than 400k rows.
In Jackson 2.0 and later you can simply use:
import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
...
ObjectMapper mapper = new ObjectMapper();
mapper.setVisibility(PropertyAccessor.ALL, Visibility.NONE);
mapper.setVisibility(PropertyAccessor.FIELD, Visibility.ANY);
to turn off autodetection.
If you used maxLength = 6
, some times what you are entering those characters are added in top of the keyboard called suggestions. So when you deleting entered letters that time it will delete suggestions first and then actual text inside EditText
. For that you need to remove the suggestions.just add
android:inputType="textNoSuggestions"`
or
android:inputType="textFilter"
It will remove those suggestions.
Don't get the request stream, quite simply. GET requests don't usually have bodies (even though it's not technically prohibited by HTTP) and WebRequest
doesn't support it - but that's what calling GetRequestStream
is for, providing body data for the request.
Given that you're trying to read from the stream, it looks to me like you actually want to get the response and read the response stream from that:
WebRequest request = WebRequest.Create(get.AbsoluteUri + args);
request.Method = "GET";
using (WebResponse response = request.GetResponse())
{
using (Stream stream = response.GetResponseStream())
{
XmlTextReader reader = new XmlTextReader(stream);
...
}
}
I faced this same issue (after setting focus through RJS/prototype) in IE. Firefox was already leaving the cursor at the end when there is already a value for the field. IE was forcing the cursor to the beginning of the text.
The solution I arrived at is as follows:
<input id="search" type="text" value="mycurrtext" size="30"
onfocus="this.value = this.value;" name="search"/>
This works in both IE7 and FF3
I like the :FuzzyFinderTextMate (or Ctrl + F) on my setup. See http://weblog.jamisbuck.org/2008/10/10/coming-home-to-vim
An answer without jQuery, with HTML elements as parameters:
This is a better approach that checks the real position of the elements as they are being shown on the viewport, even if they're absolute, relative or have been manipulated via transformations:
function isCollide(a, b) {
var aRect = a.getBoundingClientRect();
var bRect = b.getBoundingClientRect();
return !(
((aRect.top + aRect.height) < (bRect.top)) ||
(aRect.top > (bRect.top + bRect.height)) ||
((aRect.left + aRect.width) < bRect.left) ||
(aRect.left > (bRect.left + bRect.width))
);
}
The way you're writing it is equivalent to
HashMap<Object, Object> map = new HashMap<Object, Object>();
What goes inside the brackets is you communicating to the compiler what you're going to put in the HashMap so that it can do error checking for you. If Object, Object is what you actually want (probably not) you should explicitly declare it. In general you should be as explicit as you can with the declaration to facilitate error checking by the compiler. What you've described should probably be declared like this:
HashMap<String, Object> map = new HashMap<String, Object>();
That way you at least declare that your keys are going to be strings, but your values can be anything. Just remember to use a cast when you get a value back out.
If you're using phpbrew try to install json extension to fix error with undefined function json_decode():
phpbrew ext install json
You separate the values you want to return by commas:
def get_name():
# you code
return first_name, last_name
The commas indicate it's a tuple, so you could wrap your values by parentheses:
return (first_name, last_name)
Then when you call the function you a) save all values to one variable as a tuple, or b) separate your variable names by commas
name = get_name() # this is a tuple
first_name, last_name = get_name()
(first_name, last_name) = get_name() # You can put parentheses, but I find it ugly
It's pretty simple :
public function myAction()
{
$url = $this->generateUrl('blog_show', array('slug' => 'my-blog-post'));
}
Inside an action, $this->generateUrl is an alias that will use the router to get the wanted route, also you could do this that is the same :
$this->get('router')->generate('blog_show', array('slug' => 'my-blog-post'));
As the other answers have said, Spring just takes care of it, creating the beans and injecting them as required.
One of the consequences is that bean injection / property setting might occur in a different order to what your XML wiring files would seem to imply. So you need to be careful that your property setters don't do initialization that relies on other setters already having been called. The way to deal with this is to declare beans as implementing the InitializingBean
interface. This requires you to implement the afterPropertiesSet()
method, and this is where you do the critical initialization. (I also include code to check that important properties have actually been set.)
Alternatively you can use the following methods in JunitCore class http://junit.sourceforge.net/javadoc/org/junit/runner/JUnitCore.html
run (with Request , Class classes and Runner) or runClasses from your java file.
On Windows 2008 R2, I have seen application crash dumps under either

One possibility is to delete to cookie you are looking for the expiration date from and rewrite it. Then you'll know the expiration date.

See the thumbnail function of PIL's Image Module. You can use it to save smaller versions of files as various filetypes and if you're wanting to preserve as much quality as you can, consider using the ANTIALIAS
filter when you do.
Other than that, I'm not sure if there's a way to specify a maximum desired size. You could, of course, write a function that might try saving multiple versions of the file at varying qualities until a certain size is met, discarding the rest and giving you the image you wanted.

If you have multiple files and you don't want to have to type each file, I would recommend that you follow these simple steps (I am using clang-3.8
but you can use any other version):
generate all .ll
files
clang-3.8 -S -emit-llvm *.c
link them into a single one
llvm-link-3.8 -S -v -o single.ll *.ll
(Optional) Optimise your code (maybe some alias analysis)
opt-3.8 -S -O3 -aa -basicaaa -tbaa -licm single.ll -o optimised.ll
Generate assembly (generates a optimised.s
file)
llc-3.8 optimised.ll
Create executable (named a.out
)
clang-3.8 optimised.s
cdecl
is a great tool for deciphering weird syntax like function pointer declarations. You can use it to generate them as well.
As far as tips for making complicated declarations easier to parse for future maintenance (by yourself or others), I recommend making typedef
s of small chunks and using those small pieces as building blocks for larger and more complicated expressions. For example:
typedef int (*FUNC_TYPE_1)(void);
typedef double (*FUNC_TYPE_2)(void);
typedef FUNC_TYPE_1 (*FUNC_TYPE_3)(FUNC_TYPE_2);
rather than:
typedef int (*(*FUNC_TYPE_3)(double (*)(void)))(void);
cdecl
can help you out with this stuff:
cdecl> explain int (*FUNC_TYPE_1)(void)
declare FUNC_TYPE_1 as pointer to function (void) returning int
cdecl> explain double (*FUNC_TYPE_2)(void)
declare FUNC_TYPE_2 as pointer to function (void) returning double
cdecl> declare FUNC_TYPE_3 as pointer to function (pointer to function (void) returning double) returning pointer to function (void) returning int
int (*(*FUNC_TYPE_3)(double (*)(void )))(void )
And is (in fact) exactly how I generated that crazy mess above.
Also worth noting is that with update_attribute
, the desired attribute to be updated doesn't need to be white listed with attr_accessible
to update it as opposed to the mass assignment method update_attributes
which will only update attr_accessible
specified attributes.
Check the image above I hope it will help someone.

Its handy to locate the file in the finder and drag and drop that into the terminal window so you can be sure the path is the correct one, I'm not a huge terminal user so this was more comfortable for me. then you can go to the start of the path and start adding in the other parts like the shorthand UNIX commands.

As you can see additional styling rules have been added to account for some oddities in Stackoverflows preview box.
You should be able to safely ignore those rules in your project.
As of v4.0.0 this seems to be the official way to do it.
EDIT: I modified the Post to include a dropdown placed on the right side of the navbar as suggested by @Bruno. It needs its left
and right
attributes to be inverted. I added an extra snippet of css to the beginning of the example code.
Please note, that the example shows the mobile version when you click the Run code snippet
button. To view the desktop version you must click the Expand snippet
button.
.ml-auto .dropdown-menu {
left: auto !important;
right: 0px;
}
Including this in your stylesheet should do the trick.
Lets consider this situation
class Animal {
void eat() {
System.out.println("animal : eat");
}
}
class Dog extends Animal {
void eat() {
System.out.println("dog : eat");
}
void anotherEat() {
super.eat();
}
}
public class Test {
public static void main(String[] args) {
Animal a = new Animal();
a.eat();
Dog d = new Dog();
d.eat();
d.anotherEat();
}
}
The output is going to be
animal : eat
dog : eat
animal : eat
The third line is printing "animal:eat" because we are calling super.eat()
. If we called this.eat()
, it would have printed as "dog:eat".
You can use Apache commons-io for this task:
Refer to this method:
public static byte[] readFileToByteArray(File file) throws IOException
Update:
Java 7 way:
byte[] bytes = Files.readAllBytes(Paths.get(filename));
and if it is a text file and you want to convert it to String (change encoding as needed):
StandardCharsets.UTF_8.decode(ByteBuffer.wrap(bytes)).toString()
Please note instead of
public TomcatEmbeddedServletContainerFactory tomcatFactory()
I had to use the following method signature
public EmbeddedServletContainerFactory embeddedServletContainerFactory()
You could count with sql and retrieve the answer from the resultset like so:
Statment stmt = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_READ_ONLY);
ResultSet ct = stmt.executeQuery("SELECT COUNT(*) FROM [table_name]");
if(ct.next()){
td.setTotalNumRows(ct.getInt(1));
}
Here I'm counting everything but you can easily modify the SQL to count based on a criteria.
From .NET 4.5 on, there is the Stream.CopyToAsync
method
input.CopyToAsync(output);
This will return a Task
that can be continued on when completed, like so:
await input.CopyToAsync(output)
// Code from here on will be run in a continuation.
Note that depending on where the call to CopyToAsync
is made, the code that follows may or may not continue on the same thread that called it.
The SynchronizationContext
that was captured when calling await
will determine what thread the continuation will be executed on.
Additionally, this call (and this is an implementation detail subject to change) still sequences reads and writes (it just doesn't waste a threads blocking on I/O completion).
From .NET 4.0 on, there's is the Stream.CopyTo
method
input.CopyTo(output);
For .NET 3.5 and before
There isn't anything baked into the framework to assist with this; you have to copy the content manually, like so:
public static void CopyStream(Stream input, Stream output)
{
byte[] buffer = new byte[32768];
int read;
while ((read = input.Read(buffer, 0, buffer.Length)) > 0)
{
output.Write (buffer, 0, read);
}
}
Note 1: This method will allow you to report on progress (x bytes read so far ...)
Note 2: Why use a fixed buffer size and not input.Length
? Because that Length may not be available! From the docs:
If a class derived from Stream does not support seeking, calls to Length, SetLength, Position, and Seek throw a NotSupportedException.
create attribute name is "price_screen_tab_name
". and access using this simple formula.
<?php $_product = $this->getProduct(); ?>
<?php echo $_product->getData('price_screen_tab_name');?>
String element = "el5";
int x = element.charAt(2) - 48;
Subtracting ascii value of '0' = 48 from char
You can use the HTML5 pattern attribute or use JavaScript.
The pattern could look for example like this:
<input id="groupidtext" type="text" pattern="(.){6,6}" style="width: 100px;" maxlength="6" />
But the pattern attribute will only work with HTML5 browsers. For old browsers you'll need JavaScript.
As suggested in the comments to add, this will only work as soon as a form is about to be submitted. If this input is not in a form and you need validation as a user types, use JavaScript.
Override the onBackPressed()
method as per the example by codeMagic, and remove the call to super.onBackPressed();
if you do not want the default action (finishing the current activity) to be executed.
There is no built-in formula in excel, you have to add a vb script and permanently save it with your MS. Excel's installation as Add-In.

After this, From File Menu select Save Book ,from next menu select "Excel 97-2003 Add-In (*.xla)
It will save as Excel Add-In. that will be available till the Ms.Office Installation to that machine.
Now Open any Excel File in any Cell type =WordNum(<your numeric value or cell reference>)
you will see a Words equivalent of the numeric value.

Newtang's observation about the security rules aside, how are you going to know that anyone who views your page will have the correct images at c:\localfile.jpg
? You can't. Even if you think you can, you can't. It presupposes a windows environment, for one thing.
My regular question is rather "anything new or changed in repo" so whatchanged comes handy. Found it here.

var BrowserDetect;
BrowserDetect = {...};// get BrowserDetect Object from the link referenced in this answer
BrowserDetect.init();
// On page load, detect browser (with jQuery or vanilla)
if (BrowserDetect.browser === 'Explorer') {
// Add 'ie' class on every element on the page.
$('*').addClass('ie');
}
</script>
<!-- ENSURE IE STYLES ARE AVAILABLE -->
<style>
div.ie {
// do something special for div on IE browser.
}
h1.ie {
// do something special for h1 on IE browser.
}
</style>
The Object
BrowserDetect also provides version
info so we can add specific classes - for ex. $('*').addClass('ie9');
if (BrowserDetect.version == 9)
.
Good Luck....
You could also turn on autoextend for the whole database using this command:
ALTER DATABASE DATAFILE 'C:\ORACLEXE\APP\ORACLE\ORADATA\XE\SYSTEM.DBF'
AUTOEXTEND ON NEXT 1M MAXSIZE 1024M;
Just change the filepath to point to your system.dbf file.

Short answer: You can't. rm
removes files blindly, with no concept of 'trash'.
Some Unix and Linux systems try to limit its destructive ability by aliasing it to rm -i
by default, but not all do.
Long answer: Depending on your filesystem, disk activity, and how long ago the deletion occured, you may be able to recover some or all of what you deleted. If you're using an EXT3 or EXT4 formatted drive, you can check out extundelete
.
In the future, use rm
with caution. Either create a del
alias that provides interactivity, or use a file manager.
In python 2.7, the /
operator is integer division if inputs are integers.
If you want float division (which is something I always prefer), just use this special import:
from __future__ import division
See it here:
>>> 7 / 2
3
>>> from __future__ import division
>>> 7 / 2
3.5
>>>
Integer division is achieved by using //
, and modulo by using %
>>> 7 % 2
1
>>> 7 // 2
3
>>>
EDIT
As commented by user2357112
, this import has to be done before any other normal import.
You can use TypeScript's native string interpolation in case if your only goal to eliminate ugly string concatenations and boring string conversions:
var yourMessage = `Your text ${yourVariable} your text continued ${yourExpression} and so on.`
NOTE:
At the right side of the assignment statement the delimiters are neither single or double quotes, instead a special char called backtick or grave accent.
The TypeScript compiler will translate your right side special literal to a string concatenation expression. With other words this syntax is not relies the ECMAScript 6 feature instead a native TypeScript feature. Your generated javascript code remains compatible.

Not exactly, but you can say List<object>
and things will work. However, list[0].Id
won't work.
This will work at runtime in C# 4.0 by having a List<dynamic>
, that is you won't get IntelliSense.
You can check whether the variable is a number like this: $val -is [int]
This will work for numeric values, but not if the number is wrapped in quotes:
1 -is [int]
True
"1" -is [int]
False
try this formula in column E:
=IF( AND( ISNUMBER(D2), D2=G2), H2, "")
your error is the number test, ISNUMBER( ISMATCH(D2,G:G,0) )
you do check if ismatch is-a-number, (i.e. isNumber("true") or isNumber("false"), which is not!.
I hope you understand my explanation.
$('.page-address-edit').addClass('test1 test2 test3');
You could also do something like:
String str = "a + b - c * d / e < f > g >= h <= i == j";
String[] arr = str.split("(?<=\\G(\\w+(?!\\w+)|==|<=|>=|\\+|/|\\*|-|(<|>)(?!=)))\\s*");
It handles white spaces and words of variable length and produces the array:
[a, +, b, -, c, *, d, /, e, <, f, >, g, >=, h, <=, i, ==, j]
sample code:
<em><b>
<h2>Upload,Save and Download video </h2>
<form method="POST" action="" enctype="multipart/form-data">
<input type="file" name="video"/>
<input type="submit" name="submit" value="Upload"/></b>

<?php>
include("connect.php");
$errors=1;
//Targeting Folder
$target="videos/";
if(isset($_POST['submit'])){
//Targeting Folder
$target=$target.basename($_FILES['video']['name']);
//Getting Selected video Type
$type=pathinfo($target,PATHINFO_EXTENSION);
//Allow Certain File Format To Upload
if($type!='mp4' && $type!='3gp' && $type!='avi'){
echo "Only mp4,3gp,avi file format are allowed to Upload";
$errors=0;
}
//checking for Exsisting video Files
if(file_exists($target)){
echo "File Exist";
$errors=0;
}
$filesize=$_FILES['video']['size'];
if($filesize>250*2000000){
echo 'You Can not Upload Large File(more than 500MB) by Default ini setting..<a href="http://www.codenair.com/2018/03/how-to-upload-large-file-in-php.html">How to upload large file in php</a>';

One way of doing it is to use the ClientScriptManager
:
Page.ClientScript.RegisterStartupScript(
GetType(),
"MyKey",
"Myfunction();",
true);
I've copy/pasted the answer from this question here, and changed the names and spelling to fit this question.
Here is code to measure what is being asked:
#include <iostream>
struct string
{
string() {}
string(const string&) {std::cout << "string(const string&)\n";}
string& operator=(const string&) {std::cout << "string& operator=(const string&)\n";return *this;}
#if (__has_feature(cxx_rvalue_references))
string(string&&) {std::cout << "string(string&&)\n";}
string& operator=(string&&) {std::cout << "string& operator=(string&&)\n";return *this;}
#endif
};
#if PROCESS == 1
string
do_something(string inval)
{
// do stuff
return inval;
}
#elif PROCESS == 2
string
do_something(const string& inval)
{
string return_val = inval;
// do stuff
return return_val;
}
#if (__has_feature(cxx_rvalue_references))
string
do_something(string&& inval)
{
// do stuff
return std::move(inval);
}
#endif
#endif
string source() {return string();}
int main()
{
std::cout << "do_something with lvalue:\n\n";
string x;
string t = do_something(x);
#if (__has_feature(cxx_rvalue_references))
std::cout << "\ndo_something with xvalue:\n\n";
string u = do_something(std::move(x));
#endif
std::cout << "\ndo_something with prvalue:\n\n";
string v = do_something(source());
}
For me this outputs:
$ clang++ -std=c++11 -stdlib=libc++ -DPROCESS=1 test.cpp
$ a.out
do_something with lvalue:
string(const string&)
string(string&&)
do_something with xvalue:
string(string&&)
string(string&&)
do_something with prvalue:
string(string&&)
$ clang++ -std=c++11 -stdlib=libc++ -DPROCESS=2 test.cpp
$ a.out
do_something with lvalue:
string(const string&)
do_something with xvalue:
string(string&&)
do_something with prvalue:
string(string&&)
The table below summarizes my results (using clang -std=c++11). The first number is the number of copy constructions and the second number is the number of move constructions:
+----+--------+--------+---------+
| | lvalue | xvalue | prvalue |
+----+--------+--------+---------+
| p1 | 1/1 | 0/2 | 0/1 |
+----+--------+--------+---------+
| p2 | 1/0 | 0/1 | 0/1 |
+----+--------+--------+---------+
The pass-by-value solution requires only one overload but costs an extra move construction when passing lvalues and xvalues. This may or may not be acceptable for any given situation. Both solutions have advantages and disadvantages.
