The final keyword is used to declare constants.
final int FILE_TYPE = 3;
The finally keyword is used in a try catch statement to specify a block of code to execute regardless of thrown exceptions.
try
{
//stuff
}
catch(Exception e)
{
//do stuff
}
finally
{
//this is always run
}
And finally (haha), finalize im not entirely sure is a keyword, but there is a finalize() function in the Object class.
finalize will print out the count for class creation.
protected void finalize() throws Throwable {
System.out.println("Run F" );
if ( checkedOut)
System.out.println("Error: Checked out");
System.out.println("Class Create Count: " + classCreate);
}
main
while ( true) {
Book novel=new Book(true);
//System.out.println(novel.checkedOut);
//Runtime.getRuntime().runFinalization();
novel.checkIn();
new Book(true);
//System.runFinalization();
System.gc();
As you can see. The following out put show the gc got executed first time when the class count is 36.
C:\javaCode\firstClass>java TerminationCondition
Run F
Error: Checked out
Class Create Count: 36
Run F
Error: Checked out
Class Create Count: 48
Run F
Set to null. Then there are no references anymore and the object will become eligible for Garbage Collection. GC will automatically remove the object from the heap.
.NET has some handy utility methods for this sort of thing in System.Array:
PS> $a = 'a','b','c'
PS> [array]::IndexOf($a, 'b')
1
PS> [array]::IndexOf($a, 'c')
2
Good points on the above approach in the comments. Besides "just" finding an index of an item in an array, given the context of the problem, this is probably more suitable:
$letters = { 'A', 'B', 'C' }
$letters | % {$i=0} {"Value:$_ Index:$i"; $i++}
Foreach (%) can have a Begin sciptblock that executes once. We set an index variable there and then we can reference it in the process scripblock where it gets incremented before exiting the scriptblock.
Using dt.weekday_name
is deprecated since pandas 0.23.0
, instead, use dt.day_name()
:
df = pd.DataFrame({'my_dates':['2015-01-01','2015-01-02','2015-01-03'],'myvals':[1,2,3]})
df['my_dates'] = pd.to_datetime(df['my_dates'])
df['my_dates'].dt.day_name()

This article can help you Configuring PHP with MySQL for Apache 2 or IIS in Windows. Look at the section "Configure PHP and MySQL under Apache 2", point 3:
extension_dir = "c:\php\extensions" ; FOR PHP 4 ONLY
extension_dir = "c:\php\ext" ; FOR PHP 5 ONLY
You must uncomment extension_dir param line and set it to absolute path to the PHP extensions directory.
I would use the yattag library. I think it's the most pythonic way:
from yattag import Doc
doc, tag, text = Doc().tagtext()
with tag('food'):
with tag('name'):
text('French Breakfast')
with tag('price', currency='USD'):
text('6.95')
with tag('ingredients'):
for ingredient in ('baguettes', 'jam', 'butter', 'croissants'):
with tag('ingredient'):
text(ingredient)
print(doc.getvalue())
To summarize what was mentioned by Breno above
Say you have a variable with a path to a file
path = '/home/User/Desktop/myfile.py'
os.path.basename(path)
returns the string 'myfile.py'
and
os.path.dirname(path)
returns the string '/home/User/Desktop'
(without a trailing slash '/')
These functions are used when you have to get the filename/directory name given a full path name.
In case the file path is just the file name (e.g. instead of path = '/home/User/Desktop/myfile.py'
you just have myfile.py
), os.path.dirname(path)
returns an empty string.

System.out.println("----------"+s);
char ch[]=s.toCharArray();
System.out.println(" ----word is found at ");
int j=0,noc=0;
for(int i=0;i<ch.length;i++)
{
j=i;
if(ch[i]=='i' && ch[j+1]=='s')
{
System.out.println(" index "+i);
noc++;
}
}
System.out.println("----- no of occurences are "+noc);
}
}

This is not my code, I'm just pointing you to a useful resource.
I think, from my own experience on problems with more advanced data structures, that the most important thing you can do here, is to get a good knowledge on the general concept of tress as data structures. If you understand the basic mechanism behind the concept it will be quite easy to implement the solution that fits your problem. There are a lot of good sources out there describing the concept. What "saved" me years ago on this particular problem was section 2.3 in "The Art of Computer Programming".
As of Jackson 2.0, @JsonSerialize(include = xxx)
has been deprecated in favour of @JsonInclude
you could also save a reference to this
before you invoke the api
method:
componentDidMount:function(){
var that = this;
VK.init(function(){
console.info("API initialisation successful");
VK.api('users.get',{fields: 'photo_50'},function(data){
if(data.response){
that.setState({ //the error happens here
FirstName: data.response[0].first_name
});
console.info(that.state.FirstName);
}
});
}, function(){
console.info("API initialisation failed");
}, '5.34');
},
It's a "precompiled header file" -- any headers you include in stdafx.h are pre-processed to save time during subsequent compilations. You can read more about it here on MSDN.
If you're building a cross-platform application, check "Empty project" when creating your project and Visual Studio won't put any files at all in your project.
I got Jupyter notebook running in Windows 10. I found the easiest way to accomplish this task without relying upon a distro like Anaconda was to use Cygwin.
In Cygwin install python2, python2-devel, python2-numpy, python2-pip, tcl, tcl-devel, (I have included a image below of all packages I installed) and any other python packages you want that are available. This is by far the easiest option.
Then run this command to just install jupyter notebook:
python -m pip install jupyter
Below is the actual commands I ran to add more libraries just in case others need this list too:
python -m pip install scipy
python -m pip install scikit-learn
python -m pip install sklearn
python -m pip install pandas
python -m pip install matplotlib
python -m pip install jupyter
If any of the above commands fail do not worry the solution is pretty simple most of the time. What you do is look at the build failure for whatever missing package / library.
Say it is showing a missing pyzmq then close Cygwin, re-open the installer, get to the package list screen, show "full" for all, then search for the name like zmq and install those libraries and re-try the above commands.
Using this approach it was fairly simple to eventually work through all the missing dependencies successfully.
Once everything is installed then run in Cygwin goto the folder you want to be the "root" for the notebook ui tree and type:
jupyter notebook
This will start up the notebook and show some output like below:
$ jupyter notebook
[I 19:05:30.459 NotebookApp] Serving notebooks from local directory:
[I 19:05:30.459 NotebookApp] 0 active kernels
[I 19:05:30.459 NotebookApp] The Jupyter Notebook is running at:
[I 19:05:30.459 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
Copy/paste this URL into your browser when you connect for the first time, to login with a token:
http://localhost:8888/?token=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
If you are using MySql Wamp. This code work.
string con="SERVER=localhost; user id=root; password=; database=dbname";
public void delete()
{
try
{
MySqlConnection connect = new MySqlConnection(con);
MySqlDataAdapter da = new MySqlDataAdapter();
connect.Open();
da.DeleteCommand = new MySqlCommand("DELETE FROM table WHERE ID='" + ID.Text + "'", connect);
da.DeleteCommand.ExecuteNonQuery();
MessageBox.Show("Successfully Deleted");
}
catch(Exception e)
{
MessageBox.Show(e.Message);
}
}
I don't exactly understand what's the problem. Incomplete type is not the type that's "missing". Incompete type is a type that is declared but not defined (in case of struct types). To find the non-defining declaration is easy. As for the finding the missing definition... the compiler won't help you here, since that is what caused the error in the first place.
A major reason for incomplete type errors in C are typos in type names, which prevent the compiler from matching one name to the other (like in matching the declaration to the definition). But again, the compiler cannot help you here. Compiler don't make guesses about typos.
SQL Server doesn't have regular expressions. It uses the LIKE pattern matching syntax which isn't the same.
As it happens, you are close. Just need leading+trailing wildcards and move the NOT
WHERE whatever NOT LIKE '%[a-z0-9]%'

Follow this link for new updates. Use Java 8 language features
Old Answer
As of Android N preview release Android support limited features of Java 8 see Java 8 Language Features
To start using these features, you need to download and set up Android Studio 2.1 and the Android N Preview SDK, which includes the required Jack toolchain and updated Android Plugin for Gradle. If you haven't yet installed the Android N Preview SDK, see Set Up to Develop for Android N.
Supported Java 8 Language Features and APIs
Android does not currently support all Java 8 language features. However, the following features are now available when developing apps targeting the Android N Preview:
Default and static interface methods
Lambda expressions (also available on API level 23 and lower)
Method References (also available on API level 23 and lower)
There are some additional Java 8 features which Android support, you can see complete detail from Java 8 Language Features
Update
Note: The Android N bases its implementation of lambda expressions on anonymous classes. This approach allows them to be backwards compatible and executable on earlier versions of Android. To test lambda expressions on earlier versions, remember to go to your build.gradle file, and set compileSdkVersion and targetSdkVersion to 23 or lower.
Update 2
Now Android studio 3.0 stable release support Java 8 libraries and Java 8 language features (without the Jack compiler).
We had a situation where we needed to persist the URL hash across ASP.Net post backs. As the browser does not send the hash to the server by default, the only way to do it is to use some Javascript:
When the form submits, grab the hash (window.location.hash
) and store it in a server-side hidden input field Put this in a DIV with an id of "urlhash
" so we can find it easily later.
On the server you can use this value if you need to do something with it. You can even change it if you need to.
On page load on the client, check the value of this this hidden field. You will want to find it by the DIV it is contained in as the auto-generated ID won't be known. Yes, you could do some trickery here with .ClientID but we found it simpler to just use the wrapper DIV as it allows all this Javascript to live in an external file and be used in a generic fashion.
If the hidden input field has a valid value, set that as the URL hash (window.location.hash again
) and/or perform other actions.
We used jQuery to simplify the selecting of the field, etc ... all in all it ends up being a few jQuery calls, one to save the value, and another to restore it.
Before submit:
$("form").submit(function() {
$("input", "#urlhash").val(window.location.hash);
});
On page load:
var hashVal = $("input", "#urlhash").val();
if (IsHashValid(hashVal)) {
window.location.hash = hashVal;
}
IsHashValid()
can check for "undefined
" or other things you don't want to handle.
Also, make sure you use $(document).ready()
appropriately, of course.
All of this can be very confusing for an app developer that's simply using TLS to connect to their own web servers. Because ATS (App Transport Security) is becoming more important and we are encouraged to convert everything to https - I think more developers are going to encounter this issue.
My app simply exchanges data between our server and the user using the https protocol. Seeing the words "USES ENCRYPTION" in the disclaimers is a bit scary so I gave the US government office a call at their office and spoke to a representative of the Bureau of Industry and Security (BIS) http://www.bis.doc.gov/index.php/about-bis/contact-bis.
The representative asked me about my app and since it passed the "primary function test" in that it had nothing to do with security/communications and simply uses https as a channel for connecting my customer data to our servers - it fell in the EAR99 category which means it's exempt from getting government permission (see https://www.bis.doc.gov/index.php/licensing/commerce-control-list-classification/export-control-classification-number-eccn)
I hope this helps other app developers.
const regex = /myRegexp/
console.log('Hello myRegexp!'.replace(regex, 'World')) // = Hello World!
_x000D_
The Regex literal notation is commonly used to create new instances of RegExp
regex needs no additional escaping
v
/ regex / gm
^ ^ ^
start end optional modifiers
As others sugguested, you can also use the new RegExp('myRegex')
constructor.
But you will have to be especially careful with escaping:
regex: 12\d45
matches: 12345
const regex = new RegExp('12\\d45')
const equalRegex = /12\d45/
You probably need to specify which rows you want to update...
UPDATE

SET
column1 = value1,
column2 = value2
WHERE
key_value = some_value;
AndroidX is the open-source project that the Android team uses to develop, test, package, version and release libraries within Jetpack.
AndroidX is a major improvement to the original Android Support Library. Like the Support Library, AndroidX ships separately from the Android OS and provides backward-compatibility across Android releases. AndroidX fully replaces the Support Library by providing feature parity and new libraries.
AndroidX includes the following features:
All packages in AndroidX live in a consistent namespace starting with the string androidx. The Support Library packages have been mapped into the corresponding androidx.* packages. For a full mapping of all the old classes and build artifacts to the new ones, see the Package Refactoring page.
Unlike the Support Library, AndroidX packages are separately maintained and updated. The androidx packages use strict Semantic Versioning
starting with version 1.0.0. You can update AndroidX
libraries in your project independently.
All new Support Library development will occur in the AndroidX library. This includes maintenance of the original Support Library artifacts and introduction of new Jetpack components.
Using AndroidX
See Migrating to AndroidX to learn how to migrate an existing project.
If you want to use AndroidX in a new project, you need to set the compile SDK to Android 9.0 (API level 28) or higher and set both of the following Android Gradle plugin flags to true in your gradle.properties
file.
android.useAndroidX
: When set to true, the Android plugin uses the appropriate AndroidX library instead of a Support Library. The flag
is false by default if it is not specified.
android.enableJetifier
: When set to true, the Android plugin automatically migrates existing third-party libraries to use AndroidX by rewriting their binaries. The flag is false by default if it is
not specified.
For Artifact mappings see this
As far as a clean process is concerned you can use ByteArrayOutputStream object...
ByteArrayOutputStream bObj = new ByteArrayOutputStream();
bObj.reset();
//write all the values to bObj one by one using
bObj.write(byte value)
// when done you can get the byte[] using
CDRIVES = bObj.toByteArray();
//than you can repeat the similar process for CMYDOCS and IEFRAME as well,
NOTE This is not an efficient solution if you really have small array.
For installation in Windows : Download and extract to any directory (lets say c drive)
Then double click on the extracted ngrok.exe
file and you'll be able to see the command prompt
.
And just type ngrok http 4040 // here I am exposing [port 4040]
Node is able to concatenate buffers on its own now.
var newBuffer = Buffer.concat([buffer1, buffer2]);
I use a module to add a .concat
function, among others:
https://github.com/coolaj86/node-bufferjs
I know it isn't a "pure" solution, but it works very well for my purposes.
I think the easiest way would be
var items = $('img, style, ...'), itemslen = items.length;
items.bind('load', function(){
itemslen--;
if (!itemlen) // Do stuff here
});
EDIT, to be a little crazy:
var items = $('a, abbr, acronym, address, applet, area, audio, b, base, ' +
'basefont, bdo, bgsound, big, body, blockquote, br, button, canvas, ' +
'caption, center, cite, code, col, colgroup, comment, custom, dd, del, ' +
'dfn, dir, div, dl, document, dt, em, embed, fieldset, font, form, frame, ' +
'frameset, head, hn, hr, html, i, iframe, img, input, ins, isindex, kbd, ' +
'label, legend, li, link, listing, map, marquee, media, menu, meta, ' +
'nextid, nobr, noframes, noscript, object, ol, optgroup, option, p, ' +
'param, plaintext, pre, q, rt, ruby, s, samp, script, select, small, ' +
'source, span, strike, strong, style, sub, sup, table, tbody, td, ' +
'textarea, tfoot, th, thead, title, tr, tt, u, ul, var, wbr, video, ' +
'window, xmp'), itemslen = items.length;
items.bind('load', function(){
itemslen--;
if (!itemlen) // Do stuff here
});
I have routine in VB ..
but you should have 2 pictureboxes .. 1 for frame .. 1 for the image .. and it make keep the picture's size ratio
Assumed picFrame is the image frame and picImg is the image
Sub InsertPicture(ByVal oImg As Image)
Dim oFoto As Image
Dim x, y As Integer
oFoto = oImg
picImg.Visible = False
picImg.Width = picFrame.Width - 2
picImg.Height = picFrame.Height - 2
picImg.Location = New Point(1, 1)
SetPicture(picPreview, oFoto)
x = (picImg.Width - picFrame.Width) / 2
y = (picImg.Height - picFrame.Height) / 2
picImg.Location = New Point(x, y)
picImg.Visible = True
End Sub
I'm sure you can make it as C# ....
I agree with Thomas and I would choose the DECIMAL(5,4) solution at least for WPF applications.
Have a look to the MSDN Numeric Format String to know why : http://msdn.microsoft.com/en-us/library/dwhawy9k#PFormatString
The percent ("P") format specifier multiplies a number by 100 and converts it to a string that represents a percentage.
Then you would be able to use this in your XAML code:
DataFormatString="{}{0:P}"
Starting git 1.8.5 (Q4 2013), you will be able to "use a Git command, but without having to change directories".
Just like "
make -C <directory>
", "git -C <directory> ...
" tells Git to go there before doing anything else.
See commit 44e1e4 by Nazri Ramliy:
It takes more keypresses to invoke Git command in a different directory without leaving the current directory:
(cd ~/foo && git status)
git --git-dir=~/foo/.git --work-tree=~/foo status
GIT_DIR=~/foo/.git GIT_WORK_TREE=~/foo git status(cd ../..; git grep foo)
for d in d1 d2 d3; do (cd $d && git svn rebase); done
The methods shown above are acceptable for scripting but are too cumbersome for quick command line invocations.
With this new option, the above can be done with fewer keystrokes:
git -C ~/foo status
git -C ../.. grep foo
for d in d1 d2 d3; do git -C $d svn rebase; done
Since Git 2.3.4 (March 2015), and commit 6a536e2 by Karthik Nayak (KarthikNayak
), git
will treat "git -C '<path>'
" as a no-op when <path>
is empty.
'
git -C ""
' unhelpfully dies with error "Cannot change to ''
", whereas the shell treats cd ""' as a no-op.
Taking the shell's behavior as a precedent, teachgit
to treat -C ""' as a no-op, as well.
4 years later, Git 2.23 (Q3 2019) documents that 'git -C ""
' works and doesn't change directory
It's been behaving so since 6a536e2 (
git
: treat "git -C '<path>'
" as a no-op when<path>
is empty, 2015-03-06, Git v2.3.4).
That means the documentation now (finally) includes:
If '
<path>
' is present but empty, e.g.-C ""
, then the current working directory is left unchanged.
You can see git -C
used with Git 2.26 (Q1 2020), as an example.
See commit b441717, commit 9291e63, commit 5236fce, commit 10812c2, commit 62d58cd, commit b87b02c, commit 9b92070, commit 3595d10, commit f511bc0, commit f6041ab, commit f46c243, commit 99c049b, commit 3738439, commit 7717242, commit b8afb90 (20 Dec 2019) by Denton Liu (Denton-L

: inlinefull_name()
Signed-off-by: Denton Liu
Before, we were running
test_must_fail full_name
. However,test_must_fail
should only be used on git commands.
Inlinefull_name()
so that we can usetest_must_fail
on thegit
command directly.When
full_name()
was introduced in 28fb84382b ("Introduce<branch>@{upstream}
notation", 2009-09-10, Git v1.7.0-rc0 -- merge), thegit -C
option wasn't available yet (since it was introduced in 44e1e4d67d ("git
: run in a directory given with -C option", 2013-09-09, Git v1.8.5-rc0 -- merge listed in batch #5)).
As a result, the helper function removed the need to manuallycd
each time. However, sincegit -C
is available now, we can just use that instead and inlinefull_name()
.
You need to use the val()
function to get the textbox value. text
does not exist as a property only as a function and even then its not the correct function to use in this situation.
var from = $("input#fromAddress").val()
val()
is the standard function for getting the value of an input.
If anybody is looking for an option which handles nested variables, there are several such options in this github issue.
In short, you need to use "default" filter for every level of nested vars. For a variable "a.nested.var" it would look like:
- hosts: 'localhost'
tasks:
- debug:
msg: "{{ ((a | default({})).nested | default({}) ).var | default('bar') }}"
or you could set default values of empty dicts for each level of vars, maybe using "combine" filter. Or use "json_query" filter. But the option I chose seems simpler to me if you have only one level of nesting.
I tried git pull --allow-unrelated-histories
didn't work, but what solves this issue for me was:
I copied all the files on my desktop repository to another folder and then deleted the folder.
Then I clone the repo again because it is a new project.
When I copied my files again and push it worked like charm.

Well... I see that an answer was already accepted... but I think you should see another solutions anyway:
/* EXAMPLE */
DECLARE @UserAliases TABLE(UserId INT , Alias VARCHAR(10))
INSERT INTO @UserAliases (UserId,Alias) SELECT 1,'MrX'
UNION ALL SELECT 1,'MrY' UNION ALL SELECT 1,'MrA'
UNION ALL SELECT 2,'Abc' UNION ALL SELECT 2,'Xyz'
/* QUERY */
;WITH tmp AS ( SELECT DISTINCT UserId FROM @UserAliases )
SELECT
LEFT(tmp.UserId, 10) +
'/ ' +
STUFF(
( SELECT ', '+Alias
FROM @UserAliases
WHERE UserId = tmp.UserId
FOR XML PATH('')
)
, 1, 2, ''
) AS [UserId/Alias]
FROM tmp
/* -- OUTPUT

2/ Abc, Xyz

With GNU sed
:
sed 's#[^^]#[&]#g;s#\^#\\^#g;s#^#/^#;s#$#$/d#' file1 | sed -f- file2
How it works:
The first sed
produces an output like this:
/^[d][s][f]$/d
/^[s][d][f][s][d]$/d
/^[d][s][f][s][d][f]$/d
Then it is used as a sed
script by the second sed
.
Anyone can use underscore _ (its Okay)
No one should use hypen - (its Bad practice)
No one should use capital letters inside package names (Bad practice)
NOTE: Here "Bad Practice" is meant for technically you are allowed to use that, but conventionally its not in good manners to write.

You can create your own custom auth schemas that use the Authorization:
header - for example, this is how OAuth works.
As a general rule, if servers or proxies don't understand the values of standard headers, they will leave them alone and ignore them. It is creating your own header keys that can often produce unexpected results - many proxies will strip headers with names they don't recognise.
Having said that, it is possibly a better idea to use cookies to transmit the token, rather than the Authorization:
header, for the simple reason that cookies were explicitly designed to carry custom values, whereas the specification for HTTP's built in auth methods does not really say either way - if you want to see exactly what it does say, have a look here.
The other point about this is that many HTTP client libraries have built-in support for Digest and Basic auth but may make life more difficult when trying to set a raw value in the header field, whereas they will all provide easy support for cookies and will allow more or less any value within them.
Another way:
x=$'Some\nstring'
readarray -t y <<<"$x"
Or, if you don't have bash 4, the bash 3.2 equivalent:
IFS=$'\n' read -rd '' -a y <<<"$x"
You can also do it the way you were initially trying to use:
y=(${x//$'\n'/ })
This, however, will not function correctly if your string already contains spaces, such as 'line 1\nline 2'
. To make it work, you need to restrict the word separator before parsing it:
IFS=$'\n' y=(${x//$'\n'/ })
...and then, since you are changing the separator, you don't need to convert the \n
to space
anymore, so you can simplify it to:
IFS=$'\n' y=($x)
This approach will function unless $x
contains a matching globbing pattern (such as "*
") - in which case it will be replaced by the matched file name(s). The read
/readarray
methods require newer bash versions, but work in all cases.
you can also use gcc -v
command that works like gcc --version
and if you would like to now where gcc
is you can use whereis gcc
command
I hope it'll be usefull
The JPA specification says the following about persist()
.
If X is a detached object, the
EntityExistsException
may be thrown when the persist operation is invoked, or theEntityExistsException
or anotherPersistenceException
may be thrown at flush or commit time.
So using persist()
would be suitable when the object ought not to be a detached object. You might prefer to have the code throw the PersistenceException
so it fails fast.
Although the specification is unclear, persist()
might set the @GeneratedValue
@Id
for an object. merge()
however must have an object with the @Id
already generated.
Try this
subset(data, !(v1 %in% c("b","d","e")))
It is not good to manipulate with DOM (including checking of attributes) in any place except directives. You can add into scope some value indicating if link should be disabled.
But other problem is that ngDisabled does not work on anything except form controls, so you can't use it with <a>, but you can use it with <button> and style it as link.
Another way is to use lazy evaluation of expressions like isDisabled || action()
so action wouold not be called if isDisabled
is true.

@paweloque For Comparing two Map Objects in java, you can add the keys of a map to list and with those 2 lists you can use the methods retainAll() and removeAll() and add them to another common keys list and different keys list. Using the keys of the common list and different list you can iterate through map, using equals you can compare the maps.
The below code will give output like this:
Before {zoo=barbar, foo=barbar}
After {zoo=barbar, foo=barbar}
Equal: Before- barbar After- barbar
Equal: Before- barbar After- barbar

You can use the expression pipeline to achieve this:
public static Func<object, object> Caster(Type type)
{
var inputObject = Expression.Parameter(typeof(object));
return Expression.Lambda<Func<object,object>>(Expression.Convert(inputObject, type), inputPara).Compile();
}
which you can invoke like:
object objAsDesiredType = Caster(desiredType)(obj);
Drawbacks: The compilation of this lambda is slower than nearly all other methods mentioned already
Advantages: You can cache the lambda, then this should be actually the fastest method, it is identical to handwritten code at compile time
I have created a data frame in a for loop with the help of a temporary empty data frame. Because for every iteration of for loop, a new data frame will be created thereby overwriting the contents of previous iteration.
Hence I need to move the contents of the data frame to the empty data frame that was created already. It's as simple as that. We just need to use .append function as shown below :
temp_df = pd.DataFrame() #Temporary empty dataframe
for sent in Sentences:
New_df = pd.DataFrame({'words': sent.words}) #Creates a new dataframe and contains tokenized words of input sentences
temp_df = temp_df.append(New_df, ignore_index=True) #Moving the contents of newly created dataframe to the temporary dataframe
Outside the for loop, you can copy the contents of the temporary data frame into the master data frame and then delete the temporary data frame if you don't need it
Here is a function that works with jQuery (for height only, not width):
function setHeight(jq_in){
jq_in.each(function(index, elem){
// This line will work with pure Javascript (taken from NicB's answer):
elem.style.height = elem.scrollHeight+'px';
});
}
setHeight($('<put selector here>'));
Note: The op asked for a solution that does not use Javascript, however this should be helpful to many people who come across this question.
Syntax errors is not checked easily in external servers, just runtime errors.
What I do? Just like you, I use
ini_set('display_errors', 'On');
error_reporting(E_ALL);
However, before run I check syntax errors in a PHP file using an online PHP syntax checker.
The best, IMHO is PHP Code Checker
I copy all the source code, paste inside the main box and click the Analyze

You will have to hand code it, SQL Profiler reveals the following.
SMSE executes quite a long string of queries when it generates the statement.
The following query (or something along its lines) is used to extract the text:
SELECT
NULL AS [Text],
ISNULL(smsp.definition, ssmsp.definition) AS [Definition]
FROM
sys.all_objects AS sp
LEFT OUTER JOIN sys.sql_modules AS smsp ON smsp.object_id = sp.object_id
LEFT OUTER JOIN sys.system_sql_modules AS ssmsp ON ssmsp.object_id = sp.object_id
WHERE
(sp.type = N'P' OR sp.type = N'RF' OR sp.type='PC')and(sp.name=N'#test___________________________________________________________________________________________________________________00003EE1' and SCHEMA_NAME(sp.schema_id)=N'dbo')
It returns the pure CREATE which is then substituted with ALTER in code somewhere.
The SET ANSI NULL stuff and the GO statements and dates are all prepended to this.
Go with sp_helptext, its simpler ...
Nobody has mentioned the index order to access the elements of the initialized array. My example code will give an illustrative example to it.
#include <iostream>
void PrintArray(int a[3][3])
{
std::cout << "a11 = " << a[0][0] << "\t\t" << "a12 = " << a[0][1] << "\t\t" << "a13 = " << a[0][2] << std::endl;
std::cout << "a21 = " << a[1][0] << "\t\t" << "a22 = " << a[1][1] << "\t\t" << "a23 = " << a[1][2] << std::endl;
std::cout << "a31 = " << a[2][0] << "\t\t" << "a32 = " << a[2][1] << "\t\t" << "a33 = " << a[2][2] << std::endl;
std::cout << std::endl;
}
int wmain(int argc, wchar_t * argv[])
{
int a1[3][3] = { 11, 12, 13, // The most
21, 22, 23, // basic
31, 32, 33 }; // format.
int a2[][3] = { 11, 12, 13, // The first (outer) dimension
21, 22, 23, // may be omitted. The compiler
31, 32, 33 }; // will automatically deduce it.
int a3[3][3] = { {11, 12, 13}, // The elements of each
{21, 22, 23}, // second (inner) dimension
{31, 32, 33} }; // can be grouped together.
int a4[][3] = { {11, 12, 13}, // Again, the first dimension
{21, 22, 23}, // can be omitted when the
{31, 32, 33} }; // inner elements are grouped.
PrintArray(a1);
PrintArray(a2);
PrintArray(a3);
PrintArray(a4);
// This part shows in which order the elements are stored in the memory.
int * b = (int *) a1; // The output is the same for the all four arrays.
for (int i=0; i<9; i++)
{
std::cout << b[i] << '\t';
}
return 0;
}
The output is:
a11 = 11 a12 = 12 a13 = 13
a21 = 21 a22 = 22 a23 = 23
a31 = 31 a32 = 32 a33 = 33
a11 = 11 a12 = 12 a13 = 13
a21 = 21 a22 = 22 a23 = 23
a31 = 31 a32 = 32 a33 = 33
a11 = 11 a12 = 12 a13 = 13
a21 = 21 a22 = 22 a23 = 23
a31 = 31 a32 = 32 a33 = 33
a11 = 11 a12 = 12 a13 = 13
a21 = 21 a22 = 22 a23 = 23
a31 = 31 a32 = 32 a33 = 33
11 12 13 21 22 23 31 32 33
You can do this by setting the date of expiry to yesterday.
Setting it to "-1" doesn't work. That marks a cookie as a Sessioncookie.
You can also do this without a marker file.
The %s format to date is seconds since the epoch. find's -mmin flag takes an argument in minutes, so divide the difference in seconds by 60. And the "-" in front of age means find files whose last modification is less than age.
time=1312603983
now=$(date +'%s')
((age = (now - time) / 60))
find . -type f -mmin -$age
With newer versions of gnu find you can use -newermt, which makes it trivial.
I know basic use of abstract classes is to create templates for future classes. But are there any more uses of them?
Not only can you define a template for children, but Abstract Classes offer the added benefit of letting you define functionality that your child classes can utilize later.
You could not provide a default method implementation in an Interface prior to Java 8.
When should you prefer them over interfaces and when not?
Abstract Classes are a good fit if you want to provide implementation details to your children but don't want to allow an instance of your class to be directly instantiated (which allows you to partially define a class).
If you want to simply define a contract for Objects to follow, then use an Interface.
Also when are abstract methods useful?
Abstract methods are useful in the same way that defining methods in an Interface is useful. It's a way for the designer of the Abstract class to say "any child of mine MUST implement this method".
I finished my work on this stuff - that is, iOS 4 + iTunes 9.2 update of my backup decoder library for Python - http://www.iki.fi/fingon/iphonebackupdb.py

(Seems to work fine with my backups at least.)
Yes since there are 2 distinct Global Assembly Cache (GAC), you will have to manage each of them individually.
In .NET Framework 4.0, the GAC went through a few changes. The GAC was split into two, one for each CLR.
The CLR version used for both .NET Framework 2.0 and .NET Framework 3.5 is CLR 2.0. There was no need in the previous two framework releases to split GAC. The problem of breaking older applications in Net Framework 4.0.
To avoid issues between CLR 2.0 and CLR 4.0 , the GAC is now split into private GAC’s for each runtime.The main change is that CLR v2.0 applications now cannot see CLR v4.0 assemblies in the GAC.
Why?
It seems to be because there was a CLR change in .NET 4.0 but not in 2.0 to 3.5. The same thing happened with 1.1 to 2.0 CLR. It seems that the GAC has the ability to store different versions of assemblies as long as they are from the same CLR. They do not want to break old applications.
See the following information in MSDN about the GAC changes in 4.0.
For example, if both .NET 1.1 and .NET 2.0 shared the same GAC, then a .NET 1.1 application, loading an assembly from this shared GAC, could get .NET 2.0 assemblies, thereby breaking the .NET 1.1 application
The CLR version used for both .NET Framework 2.0 and .NET Framework 3.5 is CLR 2.0. As a result of this, there was no need in the previous two framework releases to split the GAC. The problem of breaking older (in this case, .NET 2.0) applications resurfaces in Net Framework 4.0 at which point CLR 4.0 released. Hence, to avoid interference issues between CLR 2.0 and CLR 4.0, the GAC is now split into private GACs for each runtime.
As the CLR is updated in future versions you can expect the same thing. If only the language changes then you can use the same GAC.
Try this regex:
^(\+?\d{1,4}[\s-])?(?!0+\s+,?$)\d{10}\s*,?$
Explanation of the regex using Perl's YAPE is as below:
NODE EXPLANATION
----------------------------------------------------------------------
(?-imsx: group, but do not capture (case-sensitive)
(with ^ and $ matching normally) (with . not
matching \n) (matching whitespace and #
normally):
----------------------------------------------------------------------
^ the beginning of the string
----------------------------------------------------------------------
( group and capture to \1 (optional
(matching the most amount possible)):
----------------------------------------------------------------------
\+? '+' (optional (matching the most amount
possible))
----------------------------------------------------------------------
\d{1,4} digits (0-9) (between 1 and 4 times
(matching the most amount possible))
----------------------------------------------------------------------
[\s-] any character of: whitespace (\n, \r,
\t, \f, and " "), '-'
----------------------------------------------------------------------
)? end of \1 (NOTE: because you are using a
quantifier on this capture, only the LAST
repetition of the captured pattern will be
stored in \1)
----------------------------------------------------------------------
(?! look ahead to see if there is not:
----------------------------------------------------------------------
0+ '0' (1 or more times (matching the most
amount possible))
----------------------------------------------------------------------
\s+ whitespace (\n, \r, \t, \f, and " ") (1
or more times (matching the most amount
possible))
----------------------------------------------------------------------
,? ',' (optional (matching the most amount
possible))
----------------------------------------------------------------------
$ before an optional \n, and the end of
the string
----------------------------------------------------------------------
) end of look-ahead
----------------------------------------------------------------------
\d{10} digits (0-9) (10 times)

To avoid SQL injection the insert statement with be
$type = 'testing';
$name = 'john';
$description = 'whatever';
$stmt = $con->prepare("INSERT INTO contents (type, reporter, description) VALUES (?, ?, ?)");
$stmt->bind_param("sss", $type , $name, $description);
$stmt->execute();
I would use underscore for this, but if that isn't available then I would drop down to using reduce with an initial value of empty object {}
>>> ['a', 'b', 'c'].reduce(function(p, c, i) {p[i] = c; return p}, {})
Object { 0="a", 1="b", 2="c"}
reduce should be widely available in most browsers today, see MDN
I think you lack to pass Connection
object to your command
object. and it is much better if you will use command
and parameters
for that.
using (SqlConnection connection = new SqlConnection("ConnectionStringHere"))
{
using (SqlCommand command = new SqlCommand())
{
command.Connection = connection; // <== lacking
command.CommandType = CommandType.Text;
command.CommandText = "INSERT into tbl_staff (staffName, userID, idDepartment) VALUES (@staffName, @userID, @idDepart)";
command.Parameters.AddWithValue("@staffName", name);
command.Parameters.AddWithValue("@userID", userId);
command.Parameters.AddWithValue("@idDepart", idDepart);
try
{
connection.Open();
int recordsAffected = command.ExecuteNonQuery();
}
catch(SqlException)
{
// error here
}
finally
{
connection.Close();
}
}
}
This should work fine everywhere templates are supported. Explicit template instantiation is part of the C++ standard.
The bottom is the top
+ the outerHeight
, not the height
, as it wouldn't include the margin or padding.
var $bot,
top,
bottom;
$bot = $('#bottom');
top = $bot.position().top;
bottom = top + $bot.outerHeight(true); //true is necessary to include the margins
$ipaddress = '';
if ($_SERVER['HTTP_CLIENT_IP'] != '127.0.0.1')
$ipaddress = $_SERVER['HTTP_CLIENT_IP'];
else if ($_SERVER['HTTP_X_FORWARDED_FOR'] != '127.0.0.1')
$ipaddress = $_SERVER['HTTP_X_FORWARDED_FOR'];
else if ($_SERVER['HTTP_X_FORWARDED'] != '127.0.0.1')
$ipaddress = $_SERVER['HTTP_X_FORWARDED'];
else if ($_SERVER['HTTP_FORWARDED_FOR'] != '127.0.0.1')
$ipaddress = $_SERVER['HTTP_FORWARDED_FOR'];
else if ($_SERVER['HTTP_FORWARDED'] != '127.0.0.1')
$ipaddress = $_SERVER['HTTP_FORWARDED'];
else if ($_SERVER['REMOTE_ADDR'] != '127.0.0.1')
$ipaddress = $_SERVER['REMOTE_ADDR'];
else
$ipaddress = 'UNKNOWN';
Just to top this up to the new Java 8 API:
DateTimeFormatter formatter = new DateTimeFormatterBuilder().appendPattern("MMMM dd, yyyy").toFormatter();
TemporalAccessor ta = formatter.parse("June 27, 2007");
Instant instant = LocalDate.from(ta).atStartOfDay().atZone(ZoneId.systemDefault()).toInstant();
Date d = Date.from(instant);
assertThat(d.getYear(), is(107));
assertThat(d.getMonth(), is(5));
A bit more verbose but you also see that the methods of Date used are deprecated ;-) Time to move on.
What about something like this.
<div id="movie_item">
<div class="movie_item_poster">
<img src="..." style="max-width: 100%; max-height: 100%;">
</div>
<div id="movie_item_content">
<div class="movie_item_content_year">year</div>
<div class="movie_item_content_title">title</div>
<div class="movie_item_content_plot">plot</div>
</div>
<div class="movie_item_toolbar">
Lorem Ipsum...
</div>
</div>
You don't have to float both movie_item_poster
AND movie_item_content
. Just float one of them...
#movie_item {
position: relative;
margin-top: 10px;
height: 175px;
}
.movie_item_poster {
float: left;
height: 150px;
width: 100px;
}
.movie_item_content {
position: relative;
}
.movie_item_content_title {
}
.movie_item_content_year {
float: right;
}
.movie_item_content_plot {
}
.movie_item_toolbar {
clear: both;
vertical-align: bottom;
width: 100%;
height: 25px;
}
I know you said that you couldn't install any software, but I'm not sure how tight that restriction is. Anyway, I had the same issue (trying to concatenate two files with presumably the same headers) and I thought I'd provide an alternative answer for others who arrive at this page, since it worked just great for me.
After trying a whole bunch of commands in windows and being severely frustrated, and also trying all sorts of graphical editors that promised to be able to open large files, but then couldn't, I finally got back to my Linux roots and opened my Cygwin prompt. Two commands:
cp file1.csv out.csv
tail -n+2 file2.csv >> out.csv
For file1.csv
800MB and file2.csv
400MB, those two commands took under 5 seconds on my machine. In a Cygwin prompt, no less. I thought Linux commands were supposed to be slow in Cygwin but that approach took far less effort and was way easier than any windows approach I could find.
The popstate event is fired when the active history entry changes. [...] The popstate event is only triggered by doing a browser action such as a click on the back button (or calling history.back() in JavaScript)
So, listening to popstate
event and sending a popstate
event when using history.pushState()
should be enough to take action on href
change:
window.addEventListener('popstate', listener);
const pushUrl = (href) => {
history.pushState({}, '', href);
window.dispatchEvent(new Event('popstate'));
};
Here is an example of passing mode as optional parameter
void myfunc(int blah, int mode = 0)
{
if (mode == 0)
do_something();
else
do_something_else();
}
you can call myfunc in both ways and both are valid
myfunc(10); // Mode will be set to default 0
myfunc(10, 1); // Mode will be set to 1
~ For those using custom input box
Private Sub CommandButton1_Click()
DoCmd.Close acForm, Me.Name
End
End Sub
The official answer from Facebook (http://developers.facebook.com/bugs/282710765082535):
Mikhail,
The facebook android sdk no longer supports android 1.5 and 1.6. Please upgrade to the next api version.
Good luck with your implementation.
This is a shortcut for $(document).ready()
, which is executed when the browser has finished loading the page (meaning here, "when the DOM is available"). See http://www.learningjquery.com/2006/09/introducing-document-ready. If you are trying to call example()
before the browser has finished loading the page, it may not work.
Your model is @Messages
, change it to @message
.
To change it like you should use migration:
def change rename_table :old_table_name, :new_table_name end
Of course do not create that file by hand but use rails generator:
rails g migration ChangeMessagesToMessage
That will generate new file with proper timestamp in name in 'db
dir. Then run:
rake db:migrate
And your app should be fine since then.
If you're using DecimalFormat
to convert double
to String
, it's very straightforward:
DecimalFormat formatter = new DecimalFormat("0.0##");
formatter.setRoundingMode(RoundingMode.HALF_UP);
double num = 1.234567;
return formatter.format(num);
There are several RoundingMode
enum values to select from, depending upon the behaviour you require.
You cannot return anonymous types. Can you create a model that can be returned? Otherwise, you must use an object
.
Here is an article written by Jon Skeet on the subject
Code from the article:
using System;
static class GrottyHacks
{
internal static T Cast<T>(object target, T example)
{
return (T) target;
}
}
class CheesecakeFactory
{
static object CreateCheesecake()
{
return new { Fruit="Strawberry", Topping="Chocolate" };
}
static void Main()
{
object weaklyTyped = CreateCheesecake();
var stronglyTyped = GrottyHacks.Cast(weaklyTyped,
new { Fruit="", Topping="" });
Console.WriteLine("Cheesecake: {0} ({1})",
stronglyTyped.Fruit, stronglyTyped.Topping);
}
}
Or, here is another similar article
Or, as others are commenting, you could use dynamic
If you want to specifically use java ArrayList then you can do something like this:
fun initList(){
val list: ArrayList<String> = ArrayList()
list.add("text")
println(list)
}
Otherwise @guenhter answer is the one you are looking for.
I know this is old but this seems to work well for me in 2020...
Using the border-image CSS property I was able to quickly manipulate the borders for this fading purpose.
Note: I don't think border-image
works well with border-radius
... I seen someone saying that somewhere but for this purpose it works well.
1 Liner:
CSS
.bbdr_rfade_1 { border: 4px solid; border-image: linear-gradient(90deg, rgba(60,74,83,0.90), rgba(60,74,83,.00)) 1; border-left:none; border-top:none; border-right:none; }
HTML
<div class = 'bbdr_rfade_1'>Oh I am so going to not up-vote this guy...</div>
Although I already wrote an overview of different kinds of popups, most people just need an Alert.
class ViewController: UIViewController {
@IBAction func showAlertButtonTapped(_ sender: UIButton) {
// create the alert
let alert = UIAlertController(title: "My Title", message: "This is my message.", preferredStyle: UIAlertController.Style.alert)
// add an action (button)
alert.addAction(UIAlertAction(title: "OK", style: UIAlertAction.Style.default, handler: nil))
// show the alert
self.present(alert, animated: true, completion: nil)
}
}
My fuller answer is here.
You can pass the struct pointer to function as function argument. It called pass by reference.
If you modify something inside that pointer, the others will be updated to. Try like this:
typedef struct client_t client_t, *pno;
struct client_t
{
pid_t pid;
char password[TAM_MAX]; // -> 50 chars
pno next;
};
pno AddClient(client_t *client)
{
/* this will change the original client value */
client.password = "secret";
}
int main()
{
client_t client;
//code ..
AddClient(&client);
}
Here's how I solved the problem today after hours of trying all of these different solutions - (for anyone looking for another way still).
Open 2 instances of cmd at your quickstart dir:
window #1:
npm run build:watch
then...
window #2:
npm run serve
It will then open in the browser and work as expected
import sys
sys.modules.keys()
An approximation of getting all imports for the current module only would be to inspect globals()
for modules:
import types
def imports():
for name, val in globals().items():
if isinstance(val, types.ModuleType):
yield val.__name__
This won't return local imports, or non-module imports like from x import y
. Note that this returns val.__name__
so you get the original module name if you used import module as alias
; yield name instead if you want the alias.
Assuming two apps TestA and TestB. TestB wants to query if TestA is installed. "TestA" defines the following URL scheme in its info.plist file:
<key>CFBundleURLTypes</key>
<array>
<dict>
<key>CFBundleURLSchemes</key>
<array>
<string>testA</string>
</array>
</dict>
</array>
The second app "TestB" tries to find out if "TestA" is installed by calling:
[[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"TestA://"]];
But this will normally return NO in iOS9 because "TestA" needs to be added to the LSApplicationQueriesSchemes entry in TestB's info.plist file. This is done by adding the following code to TestB's info.plist file:
<key>LSApplicationQueriesSchemes</key>
<array>

You can create TIMESTAMP field in table on the SQLite, see this:
CREATE TABLE my_table (
id INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL,
name VARCHAR(64),
sqltime TIMESTAMP DEFAULT CURRENT_TIMESTAMP NOT NULL
);
INSERT INTO my_table(name, sqltime) VALUES('test1', '2010-05-28T15:36:56.200');
INSERT INTO my_table(name, sqltime) VALUES('test2', '2010-08-28T13:40:02.200');
INSERT INTO my_table(name) VALUES('test3');
This is the result:
SELECT * FROM my_table;
This is my simplified example of how to run RAW SELECT, get result and access the values.
$res = DB::select('
select count(id) as c
from prices p
where p.type in (2,3)
');
if ($res[0]->c > 10)
{
throw new Exception('WOW');
}
If you want only run sql script with no return resutl use this
DB::statement('ALTER TABLE products MODIFY COLUMN physical tinyint(1) AFTER points;');
Tested in laravel 5.1
in the config.inc.php, remove all lines with "$cfg['Servers']" , and keep ONLY the "$cfg['Servers'][$i]['host']"
This question is very, very, very old, but as a trick in the future, I recommend something like this:
.element{
box-shadow: 0px 0px 10px #232931;
}
.container{
height: 100px;
width: 100px;
overflow: hidden;
}
Basically, you have a box shadow and then wrapping the element in a div with its overflow set to hidden. You'll need to adjust the height, width, and even padding of the div to only show the left box shadow, but it works. See here for an example If you look at the example, you can see how there's no other shadows, but only a black left shadow. Edit: this is a retake of the same screen shot, in case some one thinks that I just cropped out the right. You can find it here
Solution provide in the questions which you linked is correct. Problem with your implementation is that You have not specified the ID of element correctly.
Secondly you need to use load
event to execute your code. Currently DOM is not loaded hence element is not found thus you are getting error.
HTML
<div id="YourElementId" ng-app='MyModule' ng-controller="MyController">
Hi
</div>
JS Code
angular.module('MyModule', [])
.controller('MyController', function ($scope) {
$scope.myfunction = function (data) {
alert("---" + data);
};
});
window.onload = function () {
angular.element(document.getElementById('YourElementId')).scope().myfunction('test');
}
Zsh comes with colored prompts builtin. Try
autoload -U promptinit && promptinit
and then prompt -l
lists available prompts, -p fire
previews the "fire" prompt, -s fire
sets it.
When you are ready to add a prompt add something like this below the autoload line above:
prompt fade red
Ah, that would be because RegExp is not jQuery. :)
Try this page. jQuery.attr
doesn't return a String so that would certainly cause in this regard. Fortunately I believe you can just use .text()
to return the String representation.
Something like:
$("li").val("title").search(/sometext/i));
For that particular case there is file.path
:
File <- file.path("~",
"a",
"very",
"long",
"path",
"here",
"that",
"goes",
"beyond",
"80",
"characters",
"and",
"then",
"some",
"more")
setwd(File)
You can do this:
IEnumerable<object> list = new List<object>(){1, 4, 5}.AsEnumerable();
CallFunction(list);
Another way would be to encode the quotes using htmlspecialchars:
$json_array = array(
'title' => 'Example string\'s with "special" characters'
);
$json_decode = htmlspecialchars(json_encode($json_array), ENT_QUOTES, 'UTF-8');
The ally.js accessibility library provides an unofficial, test-based list here:

(NB: Their page doesn't say how often tests were performed.)
With the build 17063 of windows 10 the CURL utility was added. To download a file you can use:
curl "https://download.sysinternals.com/files/PSTools.zip" --output pstools.zip
It can be easier to use bitsadmin with a macro:
set "download=bitsadmin /transfer myDownloadJob /download /priority normal"
%download% "https://download.sysinternals.com/files/PSTools.zip" %cd%\pstools.zip
For backward compatibility you can use winhttpjs.bat (with this you can perform also POST,DELETE and the others http methods):
call winhhtpjs.bat "https://example.com/files/some.zip" -saveTo "c:\somezip.zip"
Set style= "display:none;"
. By setting visible=false
, it will not render button in the browser. Thus,client side script wont execute.
<asp:Button ID="savebtn" runat="server" OnClick="savebtn_Click" style="display:none" />
html markup should be
<button id="btnsave" onclick="fncsave()">Save</button>
Change javascript to
<script type="text/javascript">
function fncsave()
{
document.getElementById('<%= savebtn.ClientID %>').click();
}
</script>
You can insert arbitrary PowerShell script code in a double-quoted string by using a subexpression, for example, $() like so:
"C:\temp\mybackup $(get-date -f yyyy-MM-dd).zip"
And if you are getting the path from somewhere else - already as a string:
$dirName = [io.path]::GetDirectoryName($path)
$filename = [io.path]::GetFileNameWithoutExtension($path)
$ext = [io.path]::GetExtension($path)
$newPath = "$dirName\$filename $(get-date -f yyyy-MM-dd)$ext"
And if the path happens to be coming from the output of Get-ChildItem:
Get-ChildItem *.zip | Foreach {
"$($_.DirectoryName)\$($_.BaseName) $(get-date -f yyyy-MM-dd)$($_.extension)"}
None of the solutions above work perfectly.They either loses CSS or have to include/edit external CSS file. I found a perfect solution that will not lose your CSS nor you have to edit/add external CSS.
HTML:
<div id='printarea'>
<p>This is a sample text for printing purpose.</p>
<input type='button' id='btn' value='Print' onclick='printFunc();'>
</div>
<p>Do not print.</p
JQuery:
function printFunc() {
var divToPrint = document.getElementById('printarea');
var htmlToPrint = '' +
'<style type="text/css">' +
'table th, table td {' +
'border:1px solid #000;' +
'padding;0.5em;' +
'}' +
'</style>';
htmlToPrint += divToPrint.outerHTML;
newWin = window.open("");
newWin.document.write("<h3 align='center'>Print Page</h3>");
newWin.document.write(htmlToPrint);
newWin.print();
newWin.close();
}
This code will work for you, because i had a simmilar problem and this worked for me. :)
1- Override Onstart() method in your fragment-dialog class.
@Override
public void onStart() {
super.onStart();
final AlertDialog D = (AlertDialog) getDialog();
if (D != null) {
Button positive = (Button) D.getButton(Dialog.BUTTON_POSITIVE);
positive.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
if (edittext.equals("")) {
Toast.makeText(getActivity(), "EditText empty",Toast.LENGTH_SHORT).show();
} else {
D.dismiss(); //dissmiss dialog
}
}
});
}
}
DROP and TRUNC do different things:
TRUNCATE TABLE
Removes all rows from a table without logging the individual row deletions. TRUNCATE TABLE is similar to the DELETE statement with no WHERE clause; however, TRUNCATE TABLE is faster and uses fewer system and transaction log resources.
DROP TABLE
Removes one or more table definitions and all data, indexes, triggers, constraints, and permission specifications for those tables.
As far as speed is concerned the difference should be small. And anyway if you don't need the table structure at all, certainly use DROP.
NSLocale* currentLocale = [NSLocale currentLocale];
[[NSDate date] descriptionWithLocale:currentLocale];
or use
NSDateFormatter *dateFormatter=[[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
// or @"yyyy-MM-dd hh:mm:ss a" if you prefer the time with AM/PM
NSLog(@"%@",[dateFormatter stringFromDate:[NSDate date]]);
It's pretty pointless to return a const
value from a function.
It's difficult to get it to have any effect on your code:
const int foo() {
return 3;
}
int main() {
int x = foo(); // copies happily
x = 4;
}
and:
const int foo() {
return 3;
}
int main() {
foo() = 4; // not valid anyway for built-in types
}
// error: lvalue required as left operand of assignment
Though you can notice if the return type is a user-defined type:
struct T {};
const T foo() {
return T();
}
int main() {
foo() = T();
}
// error: passing ‘const T’ as ‘this’ argument of ‘T& T::operator=(const T&)’ discards qualifiers
it's questionable whether this is of any benefit to anyone.
Returning a reference is different, but unless Object
is some template parameter, you're not doing that.
You need to put the directory that has php.exe
in you WAMP
installation into your PATH
. It is usually something like C:\wamp\xampp\php

Trying to make the same code work for desktop and iPhone. The problem was that if the first option is used and you click it from a desktop browser it gives an error message, and if the second one is used it disables the tab-to-call functionality on iPhone iOS5.
So I tried and tried and it turned out that iPhone treats the phone number as a special type of link that can be formatted with CSS as one. I wrapped the number in an address tag (it would work with any other HTML tag, just try avoiding <a>
tag) and styled it in CSS as
.myDiv address a {color:#FFF; font-style: normal; text-decoration:none;}
and it worked - in a desktop browser showed a plain text and in a Safari mobile showed as a link with the Call/Cancel window popping up on tab and without the default blue color and underlining.
Just be careful with the css rules applied to the number especially when using padding/margin.
Here's the briefest explanation:
A Turing Complete system means a system in which a program can be written that will find an answer (although with no guarantees regarding runtime or memory).
So, if somebody says "my new thing is Turing Complete" that means in principle (although often not in practice) it could be used to solve any computation problem.
Sometimes it's a joke... a guy wrote a Turing Machine simulator in vi, so it's possible to say that vi is the only computational engine ever needed in the world.
You should write in file:
<script>
//write your JavaScript code here
</script>
save it with .html extension and open with browser.
For example:
// this is test.html
<script>
alert("Hello");
var a = 5;
function incr(arg){
arg++;
return arg;
}
alert(a);
</script>
As an alternative to mentioned above. Call after data load:
Swift
collectionView.reloadData()
collectionView.layoutIfNeeded()
collectionView.selectItem(at: indexPath, animated: true, scrollPosition: .right)
Still amazed that none recommended the guava library for this.
//Sample taken from a current working project of mine just to illustrate the idea
@Override
public int hashCode(){
return Objects.hashCode(this.getDate(), this.datePattern);
}
@Override
public boolean equals(Object obj){
if ( ! obj instanceof DateAndPattern ) {
return false;
}
return Objects.equal(((DateAndPattern)obj).getDate(), this.getDate())
&& Objects.equal(((DateAndPattern)obj).getDate(), this.getDatePattern());
}
I think it depends on how light/heavy the target method is. if the target method is very light(e.g. getter/setter), It could be 1 ~ 3 times slower. if the target method takes about 1 millisecond or above, then the performance will be very close. here is the test I did with Java 8 and reflectasm :
public class ReflectionTest extends TestCase {
@Test
public void test_perf() {
Profiler.run(3, 100000, 3, "m_01 by refelct", () -> Reflection.on(X.class)._new().invoke("m_01")).printResult();
Profiler.run(3, 100000, 3, "m_01 direct call", () -> new X().m_01()).printResult();
Profiler.run(3, 100000, 3, "m_02 by refelct", () -> Reflection.on(X.class)._new().invoke("m_02")).printResult();
Profiler.run(3, 100000, 3, "m_02 direct call", () -> new X().m_02()).printResult();
Profiler.run(3, 100000, 3, "m_11 by refelct", () -> Reflection.on(X.class)._new().invoke("m_11")).printResult();
Profiler.run(3, 100000, 3, "m_11 direct call", () -> X.m_11()).printResult();
Profiler.run(3, 100000, 3, "m_12 by refelct", () -> Reflection.on(X.class)._new().invoke("m_12")).printResult();
Profiler.run(3, 100000, 3, "m_12 direct call", () -> X.m_12()).printResult();
}
public static class X {
public long m_01() {
return m_11();
}
public long m_02() {
return m_12();
}
public static long m_11() {
long sum = IntStream.range(0, 10).sum();
assertEquals(45, sum);
return sum;
}
public static long m_12() {
long sum = IntStream.range(0, 10000).sum();
assertEquals(49995000, sum);
return sum;
}
}
}

You might want to try the contains
selector:
if ($("#field > div.field-item:contains('someText')").length) {
$("#somediv").addClass("thisClass");
}
Also, as other mentioned, you must use == or === rather than =.
My suggested name for this technique (including multiple top-level classes in a single source file) would be "mess". Seriously, I don't think it's a good idea - I'd use a nested type in this situation instead. Then it's still easy to predict which source file it's in. I don't believe there's an official term for this approach though.
As for whether this actually changes between implementations - I highly doubt it, but if you avoid doing it in the first place, you'll never need to care :)
Assume you wanna create folder abc/123/ in your bucket, it's a piece of cake with Boto
k = bucket.new_key('abc/123/')
k.set_contents_from_string('')
Or use the console
Include the following code in your class code.
def __iter__(self):
for x in self.iterable:
yield x
Make sure that you replace self.iterable
with the iterable which you iterate through.
Here's an example code
class someClass:
def __init__(self,list):
self.list = list
def __iter__(self):
for x in self.list:
yield x
var = someClass([1,2,3,4,5])
for num in var:
print(num)
Output
1
2
3
4
5
Note: Since strings are also iterable, they can also be used as an argument for the class
foo = someClass("Python")
for x in foo:
print(x)
Output
P
y
t
h
o
n
Following the example of the Andrzej Doyle's answer, I think the better solution is to use org.apache.commons.lang3.StringUtils.stripAccents()
:
package bla.bla.utility;
import org.apache.commons.lang3.StringUtils;
public class UriUtility {
public static String normalizeUri(String s) {
String r = StringUtils.stripAccents(s);
r = r.replace(" ", "_");
r = r.replaceAll("[^\\.A-Za-z0-9_]", "");
return r;
}
}
I would bet most users aren't the type of user that use the keyboard as a navigation control. Is it then acceptable to annoy the majority of your users for a small group that prefers to use keyboard navigation? Short answer — depends on who your users are.
Also, I don't see this experience in the same way in Firefox and Safari. So this argument seems to be mostly for IE. It all really depends on your user base and their level of knowledge — how they use the site.
If you really want to know where you are and you are a keyboard user, you can always look at the status bar as you key through the site.
[u'{email:[email protected],gem:0}', u'{email:test,gem:0}', u'{email:test,gem:0}', u'{email:test,gem:0}', u'{email:test,gem:0}', u'{email:test1,gem:0}']
'u' denotes unicode characters. We can easily remove this with map function on the final list element
map(str, test)
Another way is when you are appending it to the list
test.append(str(a))
Quite similar approve as already posted above. However it's easier to read.
/**
* Remove all empty spaces from array a string array
* @param arr array
* @return array without ""
*/
public static String[] removeAllEmpty(String[] arr) {
if (arr == null)
return arr;
String[] result = new String[arr.length];
int amountOfValidStrings = 0;
for (int i = 0; i < arr.length; i++) {
if (!arr[i].equals(""))
result[amountOfValidStrings++] = arr[i];
}
result = Arrays.copyOf(result, amountOfValidStrings);
return result;
}
I had this issue on a server of mine that was set up with it's regular IP and a failover IP. The failover IP did not point to the server at this time. I had to remove the failover IP from the server configuration in /etc/netplan/01-netcfg.yaml
. Pointing the failover IP to that server would have probably solved the issue as well.
I recently had a similar problem and I found that I need to decrease the list index by one.
So instead of:
if l[i]==0:
You can try:
if l[i-1]==0:
Because the list indices start at 0 and your range will go just one above that.
I think you can use:
pygame.time.delay(delayTime)
in which delayTime
is in milliseconds.
Put it before events.
You'll have to style your printout with @media print {}
in the CSS but the simple code is:
export default class Component extends Component {
print(){
window.print();
}
render() {
...
<span className="print"
onClick={this.print}>
PRINT
</span>
}
}
Hope that's helpful!
instead of
self.theTable.tableFooterView = tableFooter;
try
[self.theTable.tableFooterView addSubview:tableFooter];
The EntityManager.flush()
operation can be used the write all changes to the database before the transaction is committed. By default JPA does not normally write changes to the database until the transaction is committed. This is normally desirable as it avoids database access, resources and locks until required. It also allows database writes to be ordered, and batched for optimal database access, and to maintain integrity constraints and avoid deadlocks. This means that when you call persist, merge, or remove the database DML INSERT
, UPDATE
, DELETE
is not executed, until commit, or until a flush is triggered.
I know this is old, and using SPL iterator maybe just an overkill, but anyway, another solution here:
$ary = array(1, 2, 3, 4, 'last');
$ary = new ArrayIterator($ary);
$ary = new CachingIterator($ary);
foreach ($ary as $each) {
if (!$ary->hasNext()) { // we chain ArrayIterator and CachingIterator
// just to use this `hasNext()` method to see
// if this is the last element
echo $each;
}
}
The oldest but fastest way you can use is:
$cat_id = get_query_var('cat');
In App.js
import {useHistory } from "react-router-dom";
const TheContext = React.createContext(null);
const App = () => {
const history = useHistory();
<TheContext.Provider value={{ history, user }}>
<Switch>
<Route exact path="/" render={(props) => <Home {...props} />} />
<Route
exact
path="/sign-up"
render={(props) => <SignUp {...props} setUser={setUser} />}
/> ...
Then in a child component :
const Welcome = () => {
const {user, history} = React.useContext(TheContext);
....
Instead of using background-image
you can use img
directly and to get the image to spread all the width of the viewport try using max-width:100%;
and please remember don't apply any padding or margin to your main container div as they will increase the total width of the container. Using this rule you can have a image width equal to the width of the browser and the height will also change according to the aspect ratio. Thanks.
Edit: Changing the image on different size of the window
$(window).resize(function(){_x000D_
var windowWidth = $(window).width();_x000D_
var imgSrc = $('#image');_x000D_
if(windowWidth <= 400){ _x000D_
imgSrc.attr('src','http://cdn.sstatic.net/Sites/stackoverflow/company/img/logos/so/so-icon.png?v=c78bd457575a');_x000D_
}_x000D_
else if(windowWidth > 400){_x000D_
imgSrc.attr('src','http://i.stack.imgur.com/oURrw.png');_x000D_
}_x000D_
});
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="image-container">_x000D_
<img id="image" src="http://cdn.sstatic.net/Sites/stackoverflow/company/img/logos/so/so-icon.png?v=c78bd457575a" alt=""/>_x000D_
</div>
_x000D_
In this way you change your image in different size of the browser.
@Mike On Mac, type this in Terminal:
open -b com.google.chrome --args --disable-web-security
If you are calling from within Stored Procedure don't use @. In my case it returns 0
CALL SP_NAME(L_OUTPUT_PARAM)
I use this function htmlentities($string):
$msg = "<script>alert("hello")</script> <h1> Hello World </h1>" $msg = htmlentities($msg); echo $msg;
Use properties file. Here is a good start: http://www.mkyong.com/java/java-properties-file-examples/
You are trying to set the timezone for date_time which already has a timezone.
Use replace
and astimezone
functions.
local_tz = pytz.timezone('Asia/Kolkata')
current_time = datetime.now().replace(tzinfo=pytz.utc).astimezone(local_tz)
Other possibility would be place the html in a non overflow:hidden element placed 'out' of screen, like a position absolute top and left lesse then 5000px, then read this elements height. Its ugly, but work well.
I think you can get this error if your database model is not correct and the underlying data contains a null which the model is attempting to map to a non-null object.
For example, some auto-generated models can attempt to map nvarchar(1) columns to char rather than string and hence if this column contains nulls it will throw an error when you attempt to access the data.
Note, LinqPad has a compatibility option if you want it to generate a model like that, but probably doesn't do this by default, which might explain it doesn't give you the error.
I think working this way would be more easy,,, Just pass a string to this function and the job is done :) .
private static void removeduplicate(String name)
{ char[] arr = name.toCharArray();
StringBuffer modified =new StringBuffer();
for(char a:arr)
{
if(!modified.contains(Character.toString(a)))
{
modified=modified.append(Character.toString(a)) ;
}
}
System.out.println(modified);
}
Update: As mentioned in below answers Ctrl+p, Ctrl+q will now turn interactive mode into daemon mode.
Well Ctrl+C (or Ctrl+\) should detach you from the container but it will kill the container because your main process is a bash.
A little lesson about docker. The container is not a real full functional OS. When you run a container the process you launch take the PID 1 and assume init power. So when that process is terminated the daemon stop the container until a new process is launched (via docker start) (More explanation on the matter http://phusion.github.io/baseimage-docker/#intro)
If you want a container that run in detached mode all the time, i suggest you use
docker run -d foo
With an ssh server on the container. (easiest way is to follow the dockerizing openssh tutorial https://docs.docker.com/engine/examples/running_ssh_service/)
Or you can just relaunch your container via
docker start foo
(it will be detached by default)
idTABLE.parentElement.innerHTML = '<span>123 element</span> 456';
while this works, it's still recommended to use getElementById
: Do DOM tree elements with ids become global variables?
replaceChild
would work fine if you want to go to the trouble of building up your replacement, element by element, using document.createElement
and appendChild
, but I don't see the point.
I whipped this up and saw it might be useful for some. (Yes, CoffeeScript. Sue me.)
app.directive 'times', ->
link: (scope, element, attrs) ->
repeater = element.html()
scope.$watch attrs.times, (value) ->
element.html ''
return unless value?
element.html Array(value + 1).join(repeater)
To use:
<div times="customer.conversations_count">
<i class="icon-picture></i>
</div>
Can this get any simpler?
I'm wary about filters because Angular likes to re-evaluate them for no good reason all the time, and it's a huge bottleneck if you have thousands of them like I do.
This directive will even watch for changes in your model, and update the element accordingly.
another example:
Reading file one row at the time. Removing unwanted chars with from end of the string str.rstrip(chars)
with open(filename, 'r') as fileobj:
for row in fileobj:
print( row.rstrip('\n') )
see also str.strip([chars])
and str.lstrip([chars])
(python >= 2.0)
If you are that particular to pass elements to viewmodel You can use
CommandParameter="{Binding ElementName=ManualParcelScanScreen}"
In my case, this error was due to incorrect paths used to specify intents in my preferences xml file after I renamed the project. For instance, where I had:
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<Preference
android:key="pref_edit_recipe_key"
android:title="Add/Edit Recipe">
<intent
android:action="android.intent.action.VIEW"
android:targetPackage="com.ssimon.olddirectory"
android:targetClass="com.ssimon.olddirectory.RecipeEditActivity"/>
</Preference>
</PreferenceScreen>
I needed the following instead:
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<Preference
android:key="pref_edit_recipe_key"
android:title="Add/Edit Recipe">
<intent
android:action="android.intent.action.VIEW"
android:targetPackage="com.ssimon.newdirectory"
android:targetClass="com.ssimon.newdirectory.RecipeEditActivity"/>

Correcting the path names fixed the problem.
If you want to apply styles only to an element which is its parents' first child, is it better to use :first-child
pseudo-class
.social:first-child{
border-bottom: dotted 1px #6d6d6d;
padding-top: 0;
}
.social{
border: 0;
width: 330px;
height: 75px;
float: right;
text-align: left;
padding: 10px 0;
}
Then, the rule .social
has both common styles and the last element's styles.
And .social:first-child
overrides them with first element's styles.
You could also use :last-child
selector, but :first-child
is more supported by old browsers: see
https://developer.mozilla.org/en-US/docs/CSS/:first-child#Browser_compatibility and https://developer.mozilla.org/es/docs/CSS/:last-child#Browser_compatibility.
The way you declare the date property as an input looks incorrect but its hard to say if it's the only problem without seeing all your code. Rather than using @Input('date')
declare the date property like so: private _date: string;
. Also, make sure you are instantiating the model with the new
keyword. Lastly, access the property using regular dot notation.
Check your work against this example from https://www.typescriptlang.org/docs/handbook/classes.html :
let passcode = "secret passcode";
class Employee {
private _fullName: string;
get fullName(): string {
return this._fullName;
}
set fullName(newName: string) {
if (passcode && passcode == "secret passcode") {
this._fullName = newName;
}
else {
console.log("Error: Unauthorized update of employee!");
}
}
}
let employee = new Employee();
employee.fullName = "Bob Smith";
if (employee.fullName) {
console.log(employee.fullName);
}

Test_y = np.nan_to_num(Test_y)
It replaces the infinity values with high finite values and the nan values with numbers
A default constructor is a constructor that either has no parameters, or if it has parameters, all the parameters have default values.

Based on answers of neeraj t and Everton Fernandes Rosario I wrote in Kotlin, where password
is an id of an EditText in your layout.
// Show passwords' symbols.
private fun showPassword() {
password.run {
val cursorPosition = selectionStart
transformationMethod = HideReturnsTransformationMethod.getInstance()
setSelection(cursorPosition)
}
}
// Show asterisks.
private fun hidePassword() {
password.run {
val cursorPosition = selectionStart
transformationMethod = PasswordTransformationMethod.getInstance()
setSelection(cursorPosition)
}
}
There are two flavors of table valued functions. One that is just a select statement and one that can have more rows than just a select statement.
This can not have a variable:
create function Func() returns table
as
return
select 10 as ColName
You have to do like this instead:
create function Func()
returns @T table(ColName int)
as
begin
declare @Var int
set @Var = 10
insert into @T(ColName) values (@Var)
return
end
I would use Prototype's update
method which supports plain text, an HTML snippet or any JavaScript object that defines a toString
method.
$("field_name").update("New text");
The best tool for doing layouts using grid, IMHO, is graph paper and a pencil. I know you're asking for some type of program, but it really does work. I've been doing Tk programming for a couple of decades so layout comes quite easily for me, yet I still break out graph paper when I have a complex GUI.
Another thing to think about is this: The real power of Tkinter geometry managers comes from using them together*. If you set out to use only grid, or only pack, you're doing it wrong. Instead, design your GUI on paper first, then look for patterns that are best solved by one or the other. Pack is the right choice for certain types of layouts, and grid is the right choice for others. For a very small set of problems, place is the right choice. Don't limit your thinking to using only one of the geometry managers.
* The only caveat to using both geometry managers is that you should only use one per container (a container can be any widget, but typically it will be a frame).
none of that needed.... just go to:
now and load your csv file as-is. extra columns and all. it will slice and dice and use just the log & lat columns and plot it for you on google maps.
You can also use
Encoding.ASCII.GetString(ms.ToArray());
I don't think this is less efficient, but I couldn't swear to it. It also lets you choose a different encoding, whereas using a StreamReader you'd have to specify that as a parameter.
The Github application for Windows shows all remote branches of a repository. If you have deleted the branch locally with $ git branch -d [branch_name]
, the remote branch still exists in your Github repository and will appear regardless in the Windows Github application.
If you want to delete the branch completely (remotely as well), use the above command in combination with $ git push origin :[name_of_your_new_branch]
. Warning: this command erases all existing branches and may cause loss of code. Be careful, I do not think this is what you are trying to do.
However every time you delete the local branch changes, the remote branch will still appear in the application. If you do not want to keep making changes, just ignore it and do not click, otherwise you may clone the repository. If you had any more questions, please let me know.
I think I wrote an elegant solution to this problem by using namespaces. In my case, the inner class does not need to know his parent class (like the static inner class in Java). As an example I made a class called 'User' and a subclass called 'Type', used as a reference for the user types (ADMIN, OTHERS) in my example. Regards.
User.php (User class file)
<?php
namespace
{
class User
{
private $type;
public function getType(){ return $this->type;}
public function setType($type){ $this->type = $type;}
}
}
namespace User
{
class Type
{
const ADMIN = 0;
const OTHERS = 1;
}
}
?>
Using.php (An example of how to call the 'subclass')
<?php
require_once("User.php");
//calling a subclass reference:
echo "Value of user type Admin: ".User\Type::ADMIN;
?>
As he didn't specify which version of SQL server he uses (date

This may be of some help (do not literally write out the backslashes '\' in the commands, they are meant to indicate that "everything has to be on one line"):
It seems that all the commands (in grey) take any type of key file (in green) as "in" argument. Which is nice.
Here are the commands again for easier copy-pasting:
openssl rsa -in $FF -out $TF
openssl rsa -aes256 -in $FF -out $TF
openssl pkcs8 -topk8 -nocrypt -in $FF -out $TF
openssl pkcs8 -topk8 -v2 aes-256-cbc -v2prf hmacWithSHA256 -in $FF -out $TF
and

You can refer below link to understand in detail (best explanation which I could find):
https://www.programmergirl.com/java-8-map-flatmap-difference/
Both map and flatMap - accept Function. The return type of map() is a single value whereas flatMap is returning stream of values
<R> Stream<R> map(Function<? super T, ? extends R> mapper)
<R> Stream<R> flatMap(Function<? super T, ? extends Stream<? extends R>> mapper)

Hello guys Most of the codes you will find will return you server ip address not client ip address .however this code returns correct client ip address.Give it a try. For More info just check this
https://www.youtube.com/watch?v=Nkf37DsxYjI
for getting your local ip address using javascript you can use put this code inside your script tag
<script>
var RTCPeerConnection = /*window.RTCPeerConnection ||*/
window.webkitRTCPeerConnection || window.mozRTCPeerConnection;
if (RTCPeerConnection) (function () {
var rtc = new RTCPeerConnection({ iceServers: [] });
if (1 || window.mozRTCPeerConnection) {
rtc.createDataChannel('', { reliable: false });
};
rtc.onicecandidate = function (evt) {
if (evt.candidate)
grepSDP("a=" + evt.candidate.candidate);
};
rtc.createOffer(function (offerDesc) {
grepSDP(offerDesc.sdp);
rtc.setLocalDescription(offerDesc);
}, function (e) { console.warn("offer failed", e); });
var addrs = Object.create(null);
addrs["0.0.0.0"] = false;
function updateDisplay(newAddr) {
if (newAddr in addrs) return;
else addrs[newAddr] = true;
var displayAddrs = Object.keys(addrs).filter(function
(k) { return addrs[k]; });
document.getElementById('list').textContent =
displayAddrs.join(" or perhaps ") || "n/a";
}
function grepSDP(sdp) {
var hosts = [];
sdp.split('\r\n').forEach(function (line) {
if (~line.indexOf("a=candidate")) {
var parts = line.split(' '),
addr = parts[4],
type = parts[7];
if (type === 'host') updateDisplay(addr);
} else if (~line.indexOf("c=")) {
var parts = line.split(' '),
addr = parts[2];
updateDisplay(addr);
}
});
}
})(); else
{
document.getElementById('list').innerHTML = "<code>ifconfig| grep inet | grep -v inet6 | cut -d\" \" -f2 | tail -n1</code>";
document.getElementById('list').nextSibling.textContent = "In Chrome and Firefox your IP should display automatically, by the power of WebRTCskull.";
}
</script>
<body>
<div id="list"></div>
</body>
and For getting your public ip address you can use put this code inside your script tag
function getIP(json) {
document.write("My public IP address is: ", json.ip);
}
<script type="application/javascript" src="https://api.ipify.org?format=jsonp&callback=getIP"></script>

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.

will return nil if a key doesn't exist.
For what I understand, VSCode is not in AppData anymore.
So Set the default git editor by executing that command in a command prompt window:
git config --global core.editor "'C:\Program Files (x86)\Microsoft VS Code\code.exe' -w"
The parameter -w
, --wait
is to wait for window to be closed before returning. Visual Studio Code is base on Atom Editor. if you also have atom installed execute the command atom --help
. You will see the last argument in the help is wait.
Next time you do a git rebase -i HEAD~3
it will popup Visual Studio Code. Once VSCode is close then Git will take back the lead.
Note: My current version of VSCode is 0.9.2
I hope that help.

"... what version supports the new ES6 import statements?"
based on the article by Dr. Axel Rauschmayer, there is a plan to have it supported by default (without the experimental command line flag) in Node.js 10.x LTS. According to node.js's release plan as it is on 3/29, 2018, it's likely to become available after Apr 2018, while LTS of it will begin on October 2018.

We were getting an error related to this after a recent release of code to one of our development environments. We have an application that is a child of another application. This relationship has been working fine for YEARS until yesterday.
The problem:
We were getting a yellow stack trace error due to duplicate keys being entered. This is because both the web.config for the child and parent applications had this key. But this existed for many years like this without change. Why all of sudden its an issue now?
The solution:
The reason this was never a problem is because the keys AND values were always the same. Yesterday we updated our SQL connection strings to include the Application Name in the connection string. This made the string unique and all of sudden started to fail.
Without doing any research on the exact reason for this, I have to assume that when the child application inherits the parents web.config values, it ignores identical key/value pairs.
We were able to solve it by wrapping the connection string like this
<location path="." inheritInChildApplications="false">
<connectionStrings>
<!-- Updated connection strings go here -->
</connectionStrings>
</location>
Edit: I forgot to mention that I added this in the PARENTS web.config. I didn't have to modify the child's web.config.
Thanks for everyones help on this, saved our butts.

What you have is a string representing a JSON serialized javascript object. You need to deserialize it back a javascript object before being able to loop through its properties. Otherwise you will be looping through each individual character of this string.
var resultJSON = '{ "key1" : "watevr1", "key2" : "watevr2", "key3" : "watevr3" }';
var result = $.parseJSON(resultJSON);

//display the key and value pair
alert(k + ' is ' + v);
});
or simply:
arr.forEach(function (val, index, theArray) {

You would think that simply authenticating a user in Active Directory would be a pretty simple process using LDAP in PHP without the need for a library. But there are a lot of things that can complicate it pretty fast:
It's actually easier in most cases to use a LDAP library supporting the above. I ultimately ended up rolling my own library which handles all the above points: LdapTools (Well, not just for authentication, it can do much more). It can be used like the following:
use LdapTools\Configuration;
use LdapTools\DomainConfiguration;
use LdapTools\LdapManager;
$domain = (new DomainConfiguration('example.com'))
->setUsername('username') # A separate AD service account used by your app
->setPassword('password')
->setServers(['dc1', 'dc2', 'dc3'])
->setUseTls(true);
$config = new Configuration($domain);
$ldap = new LdapManager($config);
if (!$ldap->authenticate($username, $password, $message)) {
echo "Error: $message";
} else {
// Do something...
}
The authenticate call above will:
There are other libraries to do this too (Such as Adldap2). However, I felt compelled enough to provide some additional information as the most up-voted answer is actually a security risk to rely on with no input validation done and not using TLS.

CREATE TABLE CRLF
(
col1 VARCHAR(1000)
)
INSERT CRLF SELECT 'The quick brown@'
INSERT CRLF SELECT 'fox @jumped'
INSERT CRLF SELECT '@over the '
INSERT CRLF SELECT 'log@'
SELECT col1 FROM CRLF
Returns:
col1
-----------------
The quick brown@
fox @jumped
@over the
log@
(4 row(s) affected)
UPDATE CRLF
SET col1 = REPLACE(col1, '@', CHAR(13))
Looks like it can be done by replacing a placeholder with CHAR(13)
Good question, never done it myself :)
WPF only
don't have the exact code to hand, but in a recent project I think I used MouseDown event and simply put this:
frmBorderless.DragMove();
Just a follow up to @LisaD's answer.
As of 2016 (Django 1.9
), you need to type:
heroku pg:reset DATABASE_URL
heroku run python manage.py makemigrations
heroku run python manage.py migrate
This will give you a fresh new database within Heroku.
Doing this from the app delegate is NOT recommended. AppDelegate manages the app life cycle that relate to launching, suspending, terminating and so on. I suggest doing this from your initial view controller in the viewDidAppear
. You can self.presentViewController
and self.dismissViewController
from the login view controller. Store a bool
key in NSUserDefaults
to see if it's launching for the first time.
In order to change the label size you can select an appropriate size policy for the label like expanding or minimum expanding.
You can scale the pixmap by keeping its aspect ratio every time it changes:
QPixmap p; // load pixmap
// get label dimensions
int w = label->width();
int h = label->height();
// set a scaled pixmap to a w x h window keeping its aspect ratio
label->setPixmap(p.scaled(w,h,Qt::KeepAspectRatio));
There are two places where you should add this code:
resizeEvent
of the widget that contains the labelIf settings.functionName
is already a function, you could do this:
settings.functionName(t.parentNode.id);
Otherwise this should also work if settings.functionName
is just the name of the function:
if (typeof window[settings.functionName] == "function") {
window[settings.functionName](t.parentNode.id);
}
'In Visual Basic
Dim FileName = "newfile.xml" ' The Name of file with its Extension Example A.txt or A.xml
Dim FilePath ="C:\MyFolderName" & "\" & FileName 'First Name of Directory and Then Name of Folder if it exists and then attach the name of file you want to search.
If System.IO.File.Exists(FilePath) Then
MsgBox("The file exists")
Else
MsgBox("the file doesn't exist")
End If
As shown on Removing standard server headers on Windows Azure Web Sites page, you can remove headers with the following:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.webServer>
<httpProtocol>
<customHeaders>
<clear />
</customHeaders>
</httpProtocol>
<security>
<requestFiltering removeServerHeader="true"/>
</security>
</system.webServer>
<system.web>
<httpRuntime enableVersionHeader="false" />
</system.web>
</configuration>
This removes the Server header, and the X- headers.
This worked locally in my tests in Visual Studio 2015.
Have you tried using?:
left:50%;
top:50%;
margin-left:-[half the width] /* As pointed out on the comments by Chetan Sastry */
Not sure if it'll work, but it's worth a try...
Minor edit: Added the margin-left part, as pointed out on the comments by Chetan...
You can remove unwanted menu items in Page_Load, like this:
protected void Page_Load(object sender, EventArgs e)
{
if (!Roles.IsUserInRole("Admin"))
{
MenuItemCollection menuItems = mTopMenu.Items;
MenuItem adminItem = new MenuItem();
foreach (MenuItem menuItem in menuItems)
{
if (menuItem.Text == "Roles")
adminItem = menuItem;
}
menuItems.Remove(adminItem);
}
}
I'm sure there's a neater way to find the right item to remove, but this one works. You could also add all the wanted menu items in a Page_Load method, instead of adding them in the markup.
-print_certs is the option you want to use to list all of the certificates in the p7b file, you may need to specify the format of the p7b file you are reading.
You can then redirect the output to a new file to build the concatenated list of certificates.
Open the file in a text editor, you will either see Base64 (PEM) or binary data (DER).
openssl pkcs7 -inform DER -outform PEM -in certificate.p7b -print_certs > certificate_bundle.cer
