Type punning via pointer casts (as opposed to using a union) is a major example of breaking strict aliasing.

The term for T&&
when used with type deduction (such as for perfect forwarding) is known colloquially as a forwarding reference. The term "universal reference" was coined by Scott Meyers in this article, but was later changed.
That is because it may be either r-value or l-value.
Examples are:
// template
template<class T> foo(T&& t) { ... }
// auto
auto&& t = ...;
// typedef
typedef ... T;
T&& t = ...;
// decltype
decltype(...)&& t = ...;
More discussion can be found in the answer for: Syntax for universal references
Here's a solution that handles errors in requests and calls a callback after the file is written:
request(opts)
.on('error', function(err){ return callback(err)})
.pipe(fs.createWriteStream(filename))
.on('finish', function (err) {
return callback(err);
});
Project

I know it's just a matter of semantics, but I ended up using it in this form.
var lastDay = new Date(new Date(2008, 11+1,1) - 1).getDate();
console.log(lastDay);
Since functions are resolved from the inside argument, outward, it works the same.
You can then just replace the year, and month / year with the required details, whether it be from the current date. Or a particular month / year.
Have you already looked at adding a check constraint
on that column which would restrict values? Something like:
CREATE TABLE SomeTable
(
Id int NOT NULL,
Frequency varchar(200),
CONSTRAINT chk_Frequency CHECK (Frequency IN ('Daily', 'Weekly', 'Monthly', 'Yearly'))
)
To center align text
input[type='text'] { text-align:center;}
To center align the textbox in the container that it sits in, apply text-align:center to the container.
We have been using jqGrid on a project and have had some good luck with it. Lots of options for inline editing, etc. If that stuff isn't necessary, then we've just used a plain foreach loop like @Hrvoje.
I also thought this would work but it's misleading:
myStruct _m1 = {0};
When I tried this:
myStruct _m1 = {0xff};
Only the 1st byte was set to 0xff
, the remaining ones were set to 0
. So I wouldn't get into the habit of using this.
By the answer of rudivonstaden
txtBlock.Text = await response.Content.ReadAsStringAsync();
but if you don't want to make the method async you can use
txtBlock.Text = response.Content.ReadAsStringAsync();
txtBlock.Text.Wait();
Wait() it's important, bec?use we are doing async operations and we must wait for the task to complete before going ahead.
You can use $.map()
(or even the .map()
function that operates on a jQuery object) to get an array of checked values. The unary (+) operator will cast the string to a number
var arr = $.map($('input:checkbox:checked'), function(e,i) {
return +e.value;
});
console.log(arr);
Here's an example
HTTP 2.0 is a binary protocol that multiplexes numerous streams going over a single (normally TLS-encrypted) TCP connection.
The contents of each stream are HTTP 1.1 requests and responses, just encoded and packed up differently. HTTP2 adds a number of features to manage the streams, but leaves old semantics untouched.
Your header file Hash.h
declares "what class hash
should look like", but not its implementation, which is (presumably) in some other source file we'll call Hash.cpp
. By including the header in your main file, the compiler is informed of the description of class Hash
when compiling the file, but not how class Hash
actually works. When the linker tries to create the entire program, it then complains that the implementation (toHash::insert(int, char)
) cannot be found.
The solution is to link all the files together when creating the actual program binary. When using the g++ frontend, you can do this by specifying all the source files together on the command line. For example:
g++ -o main Hash.cpp main.cpp
will create the main program called "main".

Okay, since it already "leaked": You're missing zero, so the correct answer is 512
(511 is the greatest one, but it's 0 to 511, not 1 to 511).
By the way, an good followup exercise would be to generalize this:
How many different values can be represented in n binary digits (bits)?
I'd like to know, too. This helps isolate the problem for me
<connectionStrings configSource="connectionStrings.config"/>
I then keep a connectionStrings.config as well as a "{host} connectionStrings.config". It's still a problem, but if you do this for sections that differ in the two environments, you can deploy and version the same web.config.
(And I don't use VS, btw.)
By default, variables created within a script are only available to the current shell; child processes (sub-shells) will not have access to values that have been set or modified. Allowing child processes to see the values, requires use of the export command.

nonatomic
property means @synthesize
d methods are not going to be generated threadsafe -- but this is much faster than the atomic
property since extra checks are eliminated.
strong
is used with ARC and it basically helps you , by not having to worry about the retain count of an object. ARC automatically releases it for you when you are done with it.Using the keyword strong
means that you own the object.
weak
ownership means that you don't own it and it just keeps track of the object till the object it was assigned to stays , as soon as the second object is released it loses is value. For eg. obj.a=objectB;
is used and a has weak property , than its value will only be valid till objectB remains in memory.
copy
property is very well explained here
strong,weak,retain,copy,assign
are mutually exclusive so you can't use them on one single object... read the "Declared Properties " section
hoping this helps you out a bit...
I know this is a little late, but here's the solution I had to come up with for handling dates when you want to be timezone independent. Essentially it involves converting everything to UTC.
From Javascript to Server:
Send out dates as epoch values with the timezone offset removed.
var d = new Date(2015,0,1) // Jan 1, 2015
// Ajax Request to server ...
$.ajax({
url: '/target',
params: { date: d.getTime() - (d.getTimezoneOffset() * 60 * 1000) }
});
The server then recieves 1420070400000 as the date epoch.
On the Server side, convert that epoch value to a datetime object:
DateTime d = new DateTime(1970, 1, 1, 0, 0, 0).AddMilliseconds(epoch);
At this point the date is just the date/time provided by the user as they provided it. Effectively it is UTC.
Going the other way:
When the server pulls data from the database, presumably in UTC, get the difference as an epoch (making sure that both date objects are either local or UTC):
long ms = (long)utcDate.Subtract(new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc)).TotalMilliseconds;
or
long ms = (long)localDate.Subtract(new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Local)).TotalMilliseconds;
When javascript receives this value, create a new date object. However, this date object is going to be assumed local time, so you need to offset it by the current timezone:
var epochValue = 1420070400000 // value pulled from server.
var utcDateVal = new Date(epochValue);
var actualDate = new Date(utcDateVal.getTime() + (utcDateVal.getTimezoneOffset() * 60 * 1000))
console.log(utcDateVal); // Wed Dec 31 2014 19:00:00 GMT-0500 (Eastern Standard Time)
console.log(actualDate); // Thu Jan 01 2015 00:00:00 GMT-0500 (Eastern Standard Time)
As far as I know, this should work for any time zone where you need to display dates that are timezone independent.
I wouldn't really class this as "AJAX". Anyway, something like following should do the trick:
document.body.style.backgroundColor = 'pink';
You will need to change the configure port of either Apache or Nginx. After you do this you will need to restart the reconfigured servers, using the 'service' command you used.
Apache
Edit
sudo subl /etc/apache2/ports.conf
and change the 80 on the following line to something different :
Listen 80
If you just change the port or add more ports here, you will likely also have to change the VirtualHost statement in
sudo subl /etc/apache2/sites-enabled/000-default.conf
and change the 80 on the following line to something different :
<VirtualHost *:80>
then restart by :
sudo service apache2 restart
Nginx
Edit
/etc/nginx/sites-enabled/default
and change the 80 on the following line :
listen 80;
then restart by :
sudo service nginx restart
It seems all the answers assume high level languages and mainly C/C++.
But the question is tagged "assembly" and in all assemblers I know (for 8bit, 16bit, 32bit and 64bit CPUs), the definitions are much more clear:
byte = 8 bits
word = 2 bytes
dword = 4 bytes = 2Words (dword means "double word")
qword = 8 bytes = 2Dwords = 4Words ("quadruple word")
I searched it in Google and I found this:
The Google Chrome Extension file type is CRX. It is essentially a compression format. So if you want to see what is behind an extension, the scripts and the code, just change the file-type from “CRX” to “ZIP” .
Unzip the file and you will get all the info you need. This way you can see the guts, learn how to write an extension yourself, or modify it for your own needs.
Then you can pack it back up with Chrome’s internal tools which automatically create the file back into CRX. Installing it just requires a click.
just window.close()
is OK, why should write in jQuery?
In my case I was able to get it working using the .attr() method.
$("._statusDDL").attr("selected", "");
var z = new int[x.Length + y.Length];
x.CopyTo(z, 0);
y.CopyTo(z, x.Length);
In windows XP and later, there's a command: tasklist that lists all process id's.

You can execute OS-commands in Java by:
Runtime.getRuntime().exec("your command here");
If you need to handle the output of a command, see example: using Runtime.exec() in Java
string s ="000000000100";
decimal iv = 0;
decimal.TryParse(s, out iv);
Console.WriteLine((iv / 100).ToString("0.00"));
One can always go for analytical functions as well which will give you more control
select tmp.row from ( select row, rank() over(partition by id order by id desc ) as rnk from table) tmp where tmp.rnk=1
If you face issue with rank() function depending on the type of data then one can choose from row_number() or dense_rank() too.
I also had this problem. To sort out the problem of spaces in the middle of the string this line of code always works:
String field = field.replaceAll("\\s+", "");
Your original regular expression has flaws: it wouldn't match 04:00
for example.
This may work better:
^([0-1]?[0-9]|2[0-3]):[0-5][0-9]$
These work for general strings (in case you do not want to output to file/console, but store for later use or something).
boost.lexical_cast
MyStr += boost::lexical_cast<std::string>(MyInt);
String streams
//sstream.h
std::stringstream Stream;
Stream.str(MyStr);
Stream << MyInt;
MyStr = Stream.str();
// If you're using a stream (for example, cout), rather than std::string
someStream << MyInt;
This one worked for me:
Searching for all *php file in the current directory , and replace the first character of each filename to capital letter:
e.g: test.php => Test.php
for f in *php ; do mv "$f" "$(\sed 's/.*/\u&/' <<< "$f")" ; done
This worked for me:
$this->db->where('RecordDate >=', '2018-08-17 00:00:00');
$this->db->where('RecordDate <=', '2018-10-04 05:32:56');

IF()
in MySQL is a ternary function, not a control structure -- if the condition in the first argument is true, it returns the second argument; otherwise, it returns the third argument. There is no corresponding ELSEIF()
function or END IF
keyword.
The closest equivalent to what you've got would be something like:
IF(qty_1<='23', price,
IF('23'>qty_1 && qty_2<='23', price_2,
IF('23'>qty_2 && qty_3<='23', price_3,
IF('23'>qty_3, price_4, 1)
)
)
)
The conditions don't all make sense to me (it looks as though some of them may be inadvertently reversed?), but without knowing what exactly you're trying to accomplish, it's hard for me to fix that.
You should remember if you want to use the Firefox only solution, if you want to add it to the whole document you should add contextmenu="mymenu"

the second argument in ROUNDUP, eg =ROUNDUP(12345.6789,3) refers to the negative of the base-10 column with that power of 10, that you want rounded up. eg 1000 = 10^3, so to round up to the next highest 1000, use ,-3)
=ROUNDUP(12345.6789,-4) = 20,000
=ROUNDUP(12345.6789,-3) = 13,000
=ROUNDUP(12345.6789,-2) = 12,400
=ROUNDUP(12345.6789,-1) = 12,350
=ROUNDUP(12345.6789,0) = 12,346
=ROUNDUP(12345.6789,1) = 12,345.7
=ROUNDUP(12345.6789,2) = 12,345.68
=ROUNDUP(12345.6789,3) = 12,345.679
So, to answer your question: if your value is in A1, use =ROUNDUP(A1,-1)
The concatenation operator +
is a binary infix operator which, when applied to lists, returns a new list containing all the elements of each of its two operands. The list.append()
method is a mutator
on list
which appends its single object
argument (in your specific example the list c
) to the subject list
. In your example this results in c
appending a reference to itself (hence the infinite recursion).
The list.extend()
method is also a mutator method which concatenates its sequence
argument with the subject list
. Specifically, it appends each of the elements of sequence
in iteration order.
Being an operator, +
returns the result of the expression as a new value. Being a non-chaining mutator
method, list.extend()
modifies the subject list in-place and returns nothing.
I've added this due to the potential confusion which the Abel's answer above may cause by mixing the discussion of lists, sequences and arrays.
Arrays
were added to Python after sequences and lists, as a more efficient way of storing arrays of integral data types. Do not confuse arrays
with lists
. They are not the same.
From the array docs:
Arrays are sequence types and behave very much like lists, except that the type of objects stored in them is constrained. The type is specified at object creation time by using a type code, which is a single character.
Well, the most likely difference is that you still have to do an actual lookup of localhost
somewhere.
If you use 127.0.0.1
, then (intelligent) software will just turn that directly into an IP address and use it. Some implementations of gethostbyname
will detect the dotted format (and presumably the equivalent IPv6 format) and not do a lookup at all.
Otherwise, the name has to be resolved. And there's no guarantee that your hosts
file will actually be used for that resolution (first, or at all) so localhost
may become a totally different IP address.
By that I mean that, on some systems, a local hosts
file can be bypassed. The host.conf
file controls this on Linux (and many other Unices).
You can use a mail web service such as Postmark, Sendgrid etc.
Sendgrid vs Postmark vs Amazon SES and other email/SMTP API providers?

Since there is no single complete and correct answer, I will try to summarize:
In general, the expression:
if (typeof(variable) != "undefined" && variable != null)
cannot be simplified, because the variable
might be undeclared so omitting the typeof(variable) != "undefined"
would result in ReferenceError. But, you can simplify the expression according to the context:
If the variable
is global, you can simplify to:
if (window.variable != null)
If it is local, you can probably avoid situations when this variable is undeclared, and also simplify to:
if (variable != null)
If it is object property, you don't have to worry about ReferenceError:
if (obj.property != null)
Pass your date in the date object:
var d = new Date('2013-03-10T02:00:00Z');
d.toLocaleDateString().replace(/\//g, '-');
Yes. See the relevant page on the R wiki. Short answer: read.xls
from the gdata

The only reason I see not to do this directly is that you may want to examine the spreadsheet to see if it has glitches (weird headers, multiple worksheets [you can only read one at a time, although you can obviously loop over them all], included plots, etc.). But for a well-formed, rectangular spreadsheet with plain numbers and character data (i.e., not comma-formatted numbers, dates, formulas with divide-by-zero errors, missing values, etc. etc. ..) I generally have no problem with this process.
public void setHoursWorked(){
hoursWorked = hours;
}
You haven't defined hours
inside that method. hours is not passed in as a parameter, it's not declared as a variable, and it's not being used as a class member, so you get that error.
blog_development doesn't exist
You can see this in sql by the 0 rows affected
message
create it in mysql with
mysql> create database blog_development
However as you are using rails you should get used to using
$ rake db:create
to do the same task. It will use your database.yml file settings, which should include something like:
development:
adapter: mysql2
database: blog_development
pool: 5
Also become familiar with:
$ rake db:migrate # Run the database migration
$ rake db:seed # Run thew seeds file create statements
$ rake db:drop # Drop the database

JavaScript cannot access files on the local computer for security reasons, even to check their size.

JSONObject json = (JSONObject) JSONSerializer.toJSON(data);
double coolness = json.getDouble( "coolness" );
int altitude = json.getInt( "altitude" );
JSONObject pilot = json.getJSONObject("pilot");
String firstName = pilot.getString("firstName");
String lastName = pilot.getString("lastName");
System.out.println( "Coolness: " + coolness );
System.out.println( "Altitude: " + altitude );
System.out.println( "Pilot: " + lastName );
Simple solution for this problem is :
Click on the switch and then press CTL+1, It will change your switch to if-else block statement, and will resolve your problem
Be explicit - then the compiler won't warn that you perhaps made a mistake.
while ( (list = list->next) != NULL )
or
while ( (list = list->next) )
Some day you'll be glad the compiler told you, people do make that mistake ;)
I case that someone need a solution for this, this is one:
if you use a dynamic USE statement all your query need to be dynamic, because it need to be everything in the same context.
You can try with SYNONYM, is basically an ALIAS to a specific Table, this SYNONYM is inserted into the sys.synonyms table so you have access to it from any context
Look this static statement:
CREATE SYNONYM MASTER_SCHEMACOLUMNS FOR Master.INFORMATION_SCHEMA.COLUMNS
SELECT * FROM MASTER_SCHEMACOLUMNS
Now dynamic:
DECLARE @SQL VARCHAR(200)
DECLARE @CATALOG VARCHAR(200) = 'Master'
IF EXISTS(SELECT * FROM sys.synonyms s WHERE s.name = 'CURRENT_SCHEMACOLUMNS')
BEGIN
DROP SYNONYM CURRENT_SCHEMACOLUMNS
END
SELECT @SQL = 'CREATE SYNONYM CURRENT_SCHEMACOLUMNS FOR '+ @CATALOG +'.INFORMATION_SCHEMA.COLUMNS';
EXEC sp_sqlexec @SQL
--Your not dynamic Code
SELECT * FROM CURRENT_SCHEMACOLUMNS
Now just change the value of @CATALOG and you will be able to list the same table but from different catalog.
Add the following in tsconfig.json
:
"typeRoots": [ "../node_modules/@types" ]
$('#usersSearch').keyup(function() { // handle keyup event on search input field
var key = e.which || e.keyCode; // store browser agnostic keycode
if(key == 13)
$(this).closest('form').submit(); // submit parent form
}
To modify DSM's answer a bit, get_loc
has some weird properties depending on the type of index in the current version of Pandas (1.1.5) so depending on your Index type you might get back an index, a mask, or a slice. This is somewhat frustrating for me because I don't want to modify the entire columns just to extract one variable's index. Much simpler is to avoid the function altogether:

There is no way to know that the two members of the options
array came from variables named size
and color
.
They are also not necessarily called that exclusively, any variable could also point to that array.
var notSize = size;
console.log(options[0]); // It is `size` or `notSize`?
One thing you can do is use an object there instead...
var options = {
size: size,
color: color
}
Then you could access options.size
or options.color
.
Try this, it will insert the list item at index 0;

In internet explorer, if the new url is from the same domain as the current url, the window will be open without an address bar. Otherwise, it will cause an address bar to appear. One workaround is to open a page from the same domain and then redirect from that page.
A BehaviorSubject holds one value. When it is subscribed it emits the value immediately. A Subject doesn't hold a value.
Subject example (with RxJS 5 API):
const subject = new Rx.Subject();
subject.next(1);
subject.subscribe(x => console.log(x));
Console output will be empty
BehaviorSubject example:
const subject = new Rx.BehaviorSubject(0);
subject.next(1);
subject.subscribe(x => console.log(x));
Console output: 1
In addition:
BehaviorSubject
should be created with an initial value: new Rx.BehaviorSubject(1)
ReplaySubject
if you want the subject to hold more than one valueDefine the variables at the beginning of the function so if there are no records, the variables exist and you won't get the error. Check for null values in the returned array.

As others answered you, if you are creating a new project, you can separate frontend and backend and use any django rest plugin to create rest api for your frontend application. This is in the ideal world.
If you have a project with the django templating already in place, then you must load your react dom render in the page you want to load the application. In my case I had already django-pipeline and I just added the browserify extension. (https://github.com/j0hnsmith/django-pipeline-browserify)
As in the example, I loaded the app using django-pipeline:
PIPELINE = {
# ...
'javascript':{
'browserify': {
'source_filenames' : (
'js/entry-point.browserify.js',
),
'output_filename': 'js/entry-point.js',
},
}
}
Your "entry-point.browserify.js" can be an ES6 file that loads your react app in the template:
import React from 'react';
import ReactDOM from 'react-dom';
import App from './components/app.js';
import "babel-polyfill";
import { Provider } from 'react-redux';
import { createStore, applyMiddleware } from 'redux';
import promise from 'redux-promise';
import reducers from './reducers/index.js';
const createStoreWithMiddleware = applyMiddleware(
promise
)(createStore);
ReactDOM.render(
<Provider store={createStoreWithMiddleware(reducers)}>
<App/>
</Provider>
, document.getElementById('my-react-app')
);
In your django template, you can now load your app easily:
{% load pipeline %}
{% comment %}
`browserify` is a PIPELINE key setup in the settings for django
pipeline. See the example above
{% endcomment %}
{% javascript 'browserify' %}
{% comment %}
the app will be loaded here thanks to the entry point you created
in PIPELINE settings. The key is the `entry-point.browserify.js`
responsable to inject with ReactDOM.render() you react app in the div
below
{% endcomment %}
<div id="my-react-app"></div>
The advantage of using django-pipeline is that statics get processed during the collectstatic
.
To recursively remove the carriage returns (\r

Use RGB values combined with opacity to get the transparency that you wish.
For instance,
<div style=" background: rgb(255, 0, 0) ; opacity: 0.2;"> </div>
<div style=" background: rgb(255, 0, 0) ; opacity: 0.4;"> </div>
<div style=" background: rgb(255, 0, 0) ; opacity: 0.6;"> </div>
<div style=" background: rgb(255, 0, 0) ; opacity: 0.8;"> </div>
<div style=" background: rgb(255, 0, 0) ; opacity: 1;"> </div>
Similarly, with actual values without opacity, will give the below.
<div style=" background: rgb(243, 191, 189) ; "> </div>
<div style=" background: rgb(246, 143, 142) ; "> </div>
<div style=" background: rgb(249, 95 , 94) ; "> </div>
<div style=" background: rgb(252, 47, 47) ; "> </div>
<div style=" background: rgb(255, 0, 0) ; "> </div>
You can have a look at this WORKING EXAMPLE.
Now, if we specifically target your issue, here is the WORKING DEMO SPECIFIC TO YOUR ISSUE.
The HTML
<div class="social">
<img src="http://www.google.co.in/images/srpr/logo4w.png" border="0" />
</div>
The CSS:
social img{
opacity:0.5;
}
.social img:hover {
opacity:1;
background-color:black;
cursor:pointer;
background: rgb(255, 0, 0) ; opacity: 0.5;
}
Hope this helps Now.
Well, I totally agree with answers already exist on this point:
bootstrap.yml
is used to save parameters that point out where the remote configuration is and Bootstrap Application Context is created with these remote configuration.Actually, it is also able to store normal properties just the same as what application.yml
do. But pay attention on this tricky thing:
bootstrap.yml
, they will get lower precedence than almost any other property sources, including application.yml. As described here.Let's make it clear, there are two kinds of properties related to bootstrap.yml
:
bootstrap.yml
to find the properties holder (A file system, git repository or something else), and the properties we get in this way are with high precedence, so they cannot be overridden by local configuration. As described here.bootstrap.yml
. As explained early, they will get lower precedence. Use them to set defaults maybe a good idea.So the differences between putting a property on application.yml
or bootstrap.yml
in spring boot are:
bootstrap.yml
.application.yml
will get higher precedence.res_list = [x[0] for x in rows]

Dependencies are singletons within the scope of an injector. In below example, a single HeroService instance is shared among the HeroesComponent and its HeroListComponent children.
Step 1. Create singleton class with @Injectable decorator
@Injectable()
export class HeroService {
getHeroes() { return HEROES; }
}
Step 2. Inject in constructor
export class HeroListComponent {
constructor(heroService: HeroService) {
this.heroes = heroService.getHeroes();
}
Step 3. Register provider
@NgModule({
imports: [
BrowserModule,
FormsModule,
routing,
HttpModule,
JsonpModule
],
declarations: [
AppComponent,
HeroesComponent,
routedComponents
],
providers: [

by DataFrame.from_records
, reshape to Series

This is just a numpy array from the ndarray module, which lets you do all the usual numpy array things.
read
reads until it finds a newline character or the end of file, and returns a non-zero exit code if it encounters an end-of-file. So it's quite possible for it to both read a line and return a non-zero exit code.
Consequently, the following code is not safe if the input might not be terminated by a newline:
while read LINE; do
# do something with LINE
done
because the body of the while
won't be executed on the last line.
Technically speaking, a file not terminated with a newline is not a text file, and text tools may fail in odd ways on such a file. However, I'm always reluctant to fall back on that explanation.
One way to solve the problem is to test if what was read is non-empty (-n
):
while read -r LINE || [[ -n $LINE ]]; do
# do something with LINE
done
Other solutions include using mapfile
to read the file into an array, piping the file through some utility which is guaranteed to terminate the last line properly (grep .
, for example, if you don't want to deal with blank lines), or doing the iterative processing with a tool like awk
(which is usually my preference).
Note that -r
is almost certainly needed in the read
builtin; it causes read
to not reinterpret \
-sequences in the input.
For single line comment you can use Ctrl + / and for multiple line comment you can use Ctrl + Shift + / after selecting the lines you want to comment in java editor.
On Mac/OS X you can use ? + / to comment out single lines or selected blocks.
For me none of the packages mentioned above did help.
I finally managed to install lxml

Running Node and Apache on one server is trivial as they don't conflict. NodeJS is just a way to execute JavaScript server side. The real dilemma comes from accessing both Node and Apache from outside. As I see it you have two choices:
Set up Apache to proxy all matching requests to NodeJS, which will do the file uploading and whatever else in node.
Have Apache and Node on different IP:port combinations (if your server has two IPs, then one can be bound to your node listener, the other to Apache).
I'm also beginning to suspect that this might not be what you are actually looking for. If your end goal is for you to write your application logic in Nodejs and some "file handling" part that you off-load to a contractor, then its really a choice of language, not a web server.
if you want to do screen capture from Java code in Android app AFAIK you must have Root provileges.
Quote from Conda for Data Science article onto Continuum's website:
Conda vs pip
Python programmers are probably familiar with pip to download packages from PyPI and manage their requirements. Although, both conda and pip are package managers, they are very different:
- Pip is specific for Python packages and conda is language-agnostic, which means we can use conda to manage packages from any language Pip compiles from source and conda installs binaries, removing the burden of compilation
- Conda creates language-agnostic environments natively whereas pip relies on virtualenv to manage only Python environments Though it is recommended to always use conda packages, conda also includes pip, so you don’t have to choose between the two. For example, to install a python package that does not have a conda package, but is available through pip, just run, for example:
conda install pip
pip install gensim
I ran into this exact issue today. I had copied the entire /etc/httpd from RHEL 6 and put it onto a CentOS 6 system, and ensured all RPMs were installed.
Anytime apache would be started, it would silently fail. It took an strace
to find the culprit: I was using CustomLog to call a program that was not installed on the target system. Once I installed the expected program, Apache HTTP Server started right up.
In Your example, apache.yml is tasklist, but not playbook
In depends on desired architecture, You can do one of:
Convert apache.yml to role. Then define tasks in roles/apache/tasks/mail.yml and variables in roles/apache/defaults/mail.yml (vars in defaults can be overriden when role applied)
Set vars in play.yml playbook
play.yml
---
- hosts: 127.0.0.1
connection: local
sudo: false
vars:
url: czxcxz
tasks:
- include: apache.yml
apache.yml
- name: Download apache
shell: wget {{url}}
Also try changing from this:
SELECT * FROM table WHERE Contains(Column, "test") > 0;
To this:
SELECT * FROM table WHERE Contains(Column, '"*test*"') > 0;
The former will find records with values like "this is a test" and "a test-case is the plan".
The latter will also find records with values like "i am testing this" and "this is the greatest".

You can use FileUtils.deleteDirectory. JAVA can't delete the non-empty foldres with File.delete().
Realizing this answered long ago, but wanted to post different approach not presented...
Use ng-init
to tally your total. This way, you do not have to iterate in the HTML and iterate in the controller. In this scenario, I think this is a cleaner/simpler solution. (If the tallying logic was more complex, I definitely would recommend moving the logic to the controller or service as appropriate.)
<tr>
<th>Product</th>
<th>Quantity</th>
<th>Price</th>
</tr>
<tr ng-repeat="product in cart.products">
<td>{{product.name}}</td>
<td>{{product.quantity}}</td>
<td ng-init="itemTotal = product.price * product.quantity; controller.Total = controller.Total + itemTotal">{{itemTotal}} €</td>
</tr>
<tr>
<td></td>
<td>Total :</td>
<td>{{ controller.Total }}</td> // Here is the total value of my cart
</tr>
Of course, in your controller, simply define/initialize your Total
field:
// random controller snippet
function yourController($scope..., blah) {
var vm = this;
vm.Total = 0;
}
Copy a value from one row to any other qualified rows within the same table (or different tables):
UPDATE `your_table` t1, `your_table` t2
SET t1.your_field = t2.your_field
WHERE t1.other_field = some_condition
AND t1.another_field = another_condition
AND t2.source_id = 'explicit_value'
Start off by aliasing the table into 2 unique references so the SQL server can tell them apart
Next, specify the field(s) to copy.
Last, specify the conditions governing the selection of the rows
Depending on the conditions you may copy from a single row to a series, or you may copy a series to a series. You may also specify different tables, and you can even use sub-selects or joins to allow using other tables to control the relationships.
In Command prompt go to project folder and execute following:
ng g s servicename
I think you should store the size somewhere.
The null-terminated-string kind of model for determining array length is a bad idea. For instance, getting the size of the array will be O(N) when it could very easily have been O(1) otherwise.
Having that said, a good solution might be glib's Arrays, they have the added advantage of expanding automatically if you need to add more items.
P.S. to be completely honest, I haven't used much of glib, but I think it's a (very) reputable library.
<?php
$items = array();
$count = 0;
foreach($group_membership as $i => $username) {
$items[$count++] = $username;
}
print_r($items);
?>
For your purposes, if all the items are stored as str
and you just use sorted as you are using and then check for the first element and replace it with '0'
>>> l1 = ['88','NaN','67','89','81']
>>> n = sorted(l1,reverse=True)
['NaN', '89', '88', '81', '67']
>>> import math
>>> if math.isnan(float(n[0])):
... n[0] = '0'
...
>>> n
['0', '89', '88', '81', '67']

I have a working example with an img-tag, but your images won't display. The difference I see is the content-type.
I checked the github image from your post (the google doc images don't load at all because of connection failures). The image from github is delivered as content-type: text/plain, which won't get rendered as an image by your browser.
The correct content-type value for svg is image/svg+xml. So you have to make sure that svg files set the correct mime type, but that's a server issue.
Try it with http://svg.tutorial.aptico.de/grafik_svg/dummy3.svg and don't forget to specify width and height in the tag.

You may set the timeout either globally for entire server:
var server = app.listen();
server.setTimeout(500000);
or just for specific route:
app.post('/xxx', function (req, res) {
req.setTimeout(500000);
});
You can use the setText()
method. Example:
import android.widget.Button;
Button p1_button = (Button)findViewById(R.id.Player1);
p1_button.setText("Some text");
Also, just as a point of reference, Button extends TextView, hence why you can use setText()
just like with an ordinary TextView.
Use Windows Job Objects. Jobs are like process groups and can limit memory usage and process priority.

maxAccountLevel = Math.Max(maxAccountLevel, accountLevel);

Yes, this really is the fastest way. Using the Linq Min

Another solution that it is similar to those already exposed here is this one. Just before the closing body tag place this html:
<div id="resultLoading" style="display: none; width: 100%; height: 100%; position: fixed; z-index: 10000; top: 0px; left: 0px; right: 0px; bottom: 0px; margin: auto;">
<div style="width: 340px; height: 200px; text-align: center; position: fixed; top: 0px; left: 0px; right: 0px; bottom: 0px; margin: auto; z-index: 10; color: rgb(255, 255, 255);">
<div class="uil-default-css">
<img src="/images/loading-animation1.gif" style="max-width: 150px; max-height: 150px; display: block; margin-left: auto; margin-right: auto;" />
</div>
<div class="loader-text" style="display: block; font-size: 18px; font-weight: 300;"> </div>
</div>
<div style="background: rgb(0, 0, 0); opacity: 0.6; width: 100%; height: 100%; position: absolute; top: 0px;"></div>
</div>
Finally, replace .loader-text element's
content on the fly on every navigation event and turn on the #resultloading
div, note that it is initially hidden.
var showLoader = function (text) {
$('#resultLoading').show();
$('#resultLoading').find('.loader-text').html(text);
};
jQuery(document).ready(function () {
jQuery(window).on("beforeunload ", function () {
showLoader('Loading, please wait...');
});
});
This can be applied to any html based project with jQuery where you don't know which pages of your administration area will take too long to finish loading.
The gif image is 176x176px but you can use any transparent gif animation, please take into account that the image size is not important as it will be maxed to 150x150px.
Also, the function showLoader can be called on an element's click to perform an action that will further redirect the page, that is why it is provided ad an individual function. i hope this can also help anyone.

I've always used phpMailer's SMTP feature:
$mail->IsSMTP();
$mail->Host = "localhost";
And if you need debug info:
$mail->SMTPDebug = 2; // enables SMTP debug information (for testing)
// 1 = errors and messages
// 2 = messages only
For types you can use is
and if it is your own viewcontroller class then you need to use isKindOfClass
like:
let vcOnTop = self.embeddedNav.viewControllers[self.embeddedNav.viewControllers.count-1]
if vcOnTop.isKindOfClass(VcShowDirections){
return
}
short answer is no, you can't overwrite a function once its in the PHP function scope.

}
//...
unset($ihatefooexamples);

Say the data are in file data.txt
, you can use the colClasses
argument of read.table()
to skip columns. Here the data in the first 7 columns are "integer"
and we set the remaining 6 columns to "NULL"
indicating they should be skipped
> read.table("data.txt", colClasses = c(rep("integer", 7), rep("NULL", 6)),
+ header = TRUE)

Change "integer"
to one of the accepted types as detailed in ?read.table
depending on the real type of data.
data.txt
looks like this:
$ cat data.txt

2011 -21 -27 -2 -6 -10 -32 -13 -12 -27 -30 -38 -29
and was created by using
write.table(dat, file = "data.txt", row.names = FALSE)
where dat
is
dat <- structure(list(Year = 2009:2011, Jan = c(-41L, -41L, -21L), Feb = c(-27L,

row.names = c(NA, -3L))
If the number of columns is not known beforehand, the utility function count.fields
will read through the file and count the number of fields in each line.
## returns a vector equal to the number of lines in the file
count.fields("data.txt", sep = "\t")
## returns the maximum to set colClasses
max(count.fields("data.txt", sep = "\t"))
alternatively you can also do this:
p '< echo "x y"' w impulse
x and y are the coordinates of the point to which you draw a vertical bar
I install go launcher on mine, (Windows 8)=> preferences => Screens => Screen orientation => vertical (disable QWE keyboard)
puts
call the to_s
of each argument and adds a new line to each string, if it does not end with new line.
print
just output each argument by calling their to_s
.
for example:
puts "one two"
:
one two
{new line}
puts "one two\n"
:
one two
{new line} #puts will not add a new line to the result, since the string ends with a new line
print "one two"
:
one two
print "one two\n"
:
one two
{new line}
And there is another way to output: p
For each object, directly writes obj.inspect followed by a newline to the program’s standard output.
It is helpful to output debugging message.
p "aa\n\t"
: aa\n\t
Most probably it has to do with caching on the device. Catching the exception and ignoring is not nice but my problem was fixed and it seems to work.
in my case i had a custom class-level constraint that was not being called.
@CustomValidation // not called
public class MyClass {
@Lob
@Column(nullable = false)
private String name;
}
as soon as i added a field-level constraint to my class, either custom or standard, the class-level constraint started working.
@CustomValidation // now it works. super.
public class MyClass {
@Lob
@Column(nullable = false)
@NotBlank // adding this made @CustomValidation start working
private String name;
}
seems like buggy behavior to me but easy enough to work around i guess
This was bugging me too, since this was a standard feature in Sublime Text 2, but somehow automatic indentation no longer worked in Sublime Text 3 for HTML files.
My solution was to find the Miscellaneous.tmPreferences file from Sublime Text 2 (found under %AppData%/Roaming/Sublime Text 2/Packages/HTML) and copy those settings to the same file for ST3.
Now package handling has been made more difficult for ST3, but luckily you can just add the files to your %AppData%/Roaming/Sublime Text 3/Packages folder and they overwrite default settings in the install directory. Just save this file as "%AppData%/Roaming/Sublime Text 3/Packages/HTML/Miscellaneous.tmPreferences" and auto indent works again like it did in ST2.

Now you got this for dt, 2010-09-09
You have to single quote your src
string inside of the double quotes:
<div ng-include src="'views/sidepanel.html'"></div>
This warning comes because your dataframe x
is a copy of a slice. This is not easy to know why, but it has something to do with how you have come to the current state of it.
You can either create a proper dataframe
out of x by doing
x = x.copy()
This will remove the warning, but it is not the proper way
You should be using the DataFrame.loc
method, as the warning suggests, like this:
x.loc[:,'Mass32s'] = pandas.rolling_mean(x.Mass32, 5).shift(-2)
Create an array of object like this:
var nietos = [];
nietos.push({"01": nieto.label, "02": nieto.value});
return nietos;
First you create the object inside of the push method and then return the newly created array.
If you use Kotlin language you just add this code:
Create global variables of GoogleMap
and Marker
types.
I use variable marker to make variable marker value can change directly
private lateinit var map: GoogleMap
private lateinit var marker: Marker
And I use this function/method to add the marker on my map:
private fun placeMarkerOnMap(location: LatLng) {
val markerOptions = MarkerOptions().position(location)
val titleStr = getAddress(location)
markerOptions.title(titleStr)
marker = map.addMarker(markerOptions)
}
After I create the function I place this code on the onMapReady()
to remove the marker and create a new one:
map.setOnMapClickListener { location ->
map.clear()
marker.remove()
placeMarkerOnMap(location)
}
It's bonus if you want to display the address location when you click the marker add this code to hide and show the marker address but you need a method to get the address location. I got the code from this post: How to get complete address from latitude and longitude?
map.setOnMarkerClickListener {marker ->
if (marker.isInfoWindowShown){
marker.hideInfoWindow()
}else{
marker.showInfoWindow()
}
true
}
There is no way to convert a VBScript (.vbs file) into an executable (.exe file) because VBScript is not a compiled language. The process of converting source code into native executable code is called "compilation", and it's not supported by scripting languages like VBScript.
Certainly you can add your script to a self-extracting archive using something like WinZip, but all that will do is compress it. It's doubtful that the file size will shrink noticeably, and since it's a plain-text file to begin with, it's really not necessary to compress it at all. The only purpose of a self-extracting archive is that decompression software (like WinZip) is not required on the end user's computer to be able to extract or "decompress" the file. If it isn't compressed in the first place, this is a moot point.
Alternatively, as you mentioned, there are ways to wrap VBScript code files in a standalone executable file, but these are just wrappers that automatically execute the script (in its current, uncompiled state) when the user double-clicks on the .exe file. I suppose that can have its benefits, but it doesn't sound like what you're looking for.
In order to truly convert your VBScript into an executable file, you're going to have to rewrite it in another language that can be compiled. Visual Basic 6 (the latest version of VB, before the .NET Framework was introduced) is extremely similar in syntax to VBScript, but does support compiling to native code. If you move your VBScript code to VB 6, you can compile it into a native executable. Running the .exe file will require that the user has the VB 6 Run-time libraries installed, but they come built into most versions of Windows that are found now in the wild.
Alternatively, you could go ahead and make the jump to Visual Basic .NET, which remains somewhat similar in syntax to VB 6 and VBScript (although it won't be anywhere near a cut-and-paste migration). VB.NET programs will also compile to an .exe file, but they require the .NET Framework runtime to be installed on the user's computer. Fortunately, this has also become commonplace, and it can be easily redistributed if your users don't happen to have it. You mentioned going this route in your question (porting your current script in to VB Express 2008, which uses VB.NET), but that you were getting a lot of errors. That's what I mean about it being far from a cut-and-paste migration. There are some huge differences between VB 6/VBScript and VB.NET, despite some superficial syntactical similarities. If you want help migrating over your VBScript, you could post a question here on Stack Overflow. Ultimately, this is probably the best way to do what you want, but I can't promise you that it will be simple.
Scanner.hasNextXXX
methodsjava.util.Scanner
has many hasNextXXX
methods that can be used to validate input. Here's a brief overview of all of them:
hasNext()
- does it have any token at all?hasNextLine()
- does it have another line of input?hasNextInt()
- does it have a token that can be parsed into an int
?hasNextDouble()
, hasNextFloat()
, hasNextByte()
, hasNextShort()
, hasNextLong()
, and hasNextBoolean()
hasNextBigInteger()
and hasNextBigDecimal()
hasNext(String pattern)
hasNext(Pattern pattern)
is the Pattern.compile
overloadScanner
is capable of more, enabled by the fact that it's regex-based. One important feature is useDelimiter(String pattern)
, which lets you define what pattern separates your tokens. There are also find
and skip
methods that ignores delimiters.
The following discussion will keep the regex as simple as possible, so the focus remains on Scanner
.
Here's a simple example of using hasNextInt()
to validate positive int
from the input.
Scanner sc = new Scanner(System.in);
int number;
do {
System.out.println("Please enter a positive number!");
while (!sc.hasNextInt()) {
System.out.println("That's not a number!");
sc.next(); // this is important!
}
number = sc.nextInt();
} while (number <= 0);
System.out.println("Thank you! Got " + number);
Here's an example session:
Please enter a positive number!
five
That's not a number!
-3
Please enter a positive number!
5
Thank you! Got 5
Note how much easier Scanner.hasNextInt()
is to use compared to the more verbose try/catch
Integer.parseInt
/NumberFormatException
combo. By contract, a Scanner
guarantees that if it hasNextInt()
, then nextInt()
will peacefully give you that int
, and will not throw any NumberFormatException
/InputMismatchException
/NoSuchElementException
.
hasNextXXX
on the same tokenNote that the snippet above contains a sc.next()
statement to advance the Scanner
until it hasNextInt()
. It's important to realize that none of the hasNextXXX
methods advance the Scanner
past any input! You will find that if you omit this line from the snippet, then it'd go into an infinite loop on an invalid input!
This has two consequences:
hasNextXXX
test, then you need to advance the Scanner
one way or another (e.g. next()
, nextLine()
, skip
, etc).hasNextXXX
test fails, you can still test if it perhaps hasNextYYY
!Here's an example of performing multiple hasNextXXX
tests.
Scanner sc = new Scanner(System.in);
while (!sc.hasNext("exit")) {
System.out.println(
sc.hasNextInt() ? "(int) " + sc.nextInt() :
sc.hasNextLong() ? "(long) " + sc.nextLong() :
sc.hasNextDouble() ? "(double) " + sc.nextDouble() :
sc.hasNextBoolean() ? "(boolean) " + sc.nextBoolean() :
"(String) " + sc.next()
);
}
Here's an example session:
5
(int) 5
false
(boolean) false
blah
(String) blah
1.1
(double) 1.1
100000000000
(long) 100000000000
exit
Note that the order of the tests matters. If a Scanner
hasNextInt()
, then it also hasNextLong()
, but it's not necessarily true
the other way around. More often than not you'd want to do the more specific test before the more general test.
Scanner
has many advanced features supported by regular expressions. Here's an example of using it to validate vowels.
Scanner sc = new Scanner(System.in);
System.out.println("Please enter a vowel, lowercase!");
while (!sc.hasNext("[aeiou]")) {
System.out.println("That's not a vowel!");
sc.next();
}
String vowel = sc.next();
System.out.println("Thank you! Got " + vowel);
Here's an example session:
Please enter a vowel, lowercase!
5
That's not a vowel!
z
That's not a vowel!
e
Thank you! Got e
In regex, as a Java string literal, the pattern "[aeiou]"
is what is called a "character class"; it matches any of the letters a
, e
, i
, o
, u
. Note that it's trivial to make the above test case-insensitive: just provide such regex pattern to the Scanner
.
hasNext(String pattern)
- Returns true
if the next token matches the pattern constructed from the specified string.java.util.regex.Pattern
Scanner
at onceSometimes you need to scan line-by-line, with multiple tokens on a line. The easiest way to accomplish this is to use two Scanner
, where the second Scanner
takes the nextLine()
from the first Scanner
as input. Here's an example:
Scanner sc = new Scanner(System.in);
System.out.println("Give me a bunch of numbers in a line (or 'exit')");
while (!sc.hasNext("exit")) {
Scanner lineSc = new Scanner(sc.nextLine());
int sum = 0;
while (lineSc.hasNextInt()) {
sum += lineSc.nextInt();
}
System.out.println("Sum is " + sum);
}
Here's an example session:
Give me a bunch of numbers in a line (or 'exit')
3 4 5
Sum is 12
10 100 a million dollar
Sum is 110
wait what?
Sum is 0
exit
In addition to Scanner(String)
constructor, there's also Scanner(java.io.File)
among others.
Scanner
provides a rich set of features, such as hasNextXXX
methods for validation.hasNextXXX/nextXXX
in combination means that a Scanner
will NEVER throw an InputMismatchException
/NoSuchElementException
.hasNextXXX
does not advance the Scanner
past any input.Scanner
if necessary. Two simple Scanner
is often better than one overly complex Scanner
.Scanner
method that takes a String pattern
argument is regex-based.
String
into a literal pattern is to Pattern.quote
it.I modified mine to return a string rather than use a ref variable like below.
public static string Serialize<T>(this T value)
{
if (value == null)
{
return string.Empty;
}
try
{
var xmlserializer = new XmlSerializer(typeof(T));
var stringWriter = new StringWriter();
using (var writer = XmlWriter.Create(stringWriter))
{
xmlserializer.Serialize(writer, value);
return stringWriter.ToString();
}
}
catch (Exception ex)
{
throw new Exception("An error occurred", ex);
}
}
Its usage would be like this:
var xmlString = obj.Serialize();
I also had this exact error message, for me the problem was fixed by adding an " \"
It turns out that my long string, broken into about eight lines with " \" at the very end, was missing a " \" on one line.
Python IDLE didn't specify a line number that this error was on, but it red-highlighted a totally correct variable assignment statement, throwing me off. The actual misshapen string statement (multiple lines long with " \") was adjacent to the statement being highlighted. Maybe this will help someone else.
The best thing is to actually use the kernel makefile to install the module:
Here is are snippets to add to your Makefile
around the top add:
PWD=$(shell pwd)
VER=$(shell uname -r)
KERNEL_BUILD=/lib/modules/$(VER)/build
# Later if you want to package the module binary you can provide an INSTALL_ROOT
# INSTALL_ROOT=/tmp/install-root
around the end add:
install:
$(MAKE) -C $(KERNEL_BUILD) M=$(PWD) \
INSTALL_MOD_PATH=$(INSTALL_ROOT) modules_install
and then you can issue
sudo make install
this will put it either in /lib/modules/$(uname -r)/extra/
or /lib/modules/$(uname -r)/misc/
and run depmod appropriately
I really like this function:
function guidGenerator() {
var S4 = function() {
return (((1+Math.random())*0x10000)|0).toString(16).substring(1);
};
return (S4()+S4()+"-"+S4()+"-"+S4()+"-"+S4()+"-"+S4()+S4()+S4());
}
class A extends B {}
class B extends C {}
Then A has extended both B and C
This does almost everything you want:
f = open('data.txt', 'rb')
while True:
char = f.read(1)
if not char: break
print "{:02x}".format(ord(char)),
With data.txt created like this:
f = open('data.txt', 'wb')
f.write("ab\r\ncd")
f.close()
I get the following output:
61 62 0d 0a 63 64
tl;dr -- 1. You are using poor variable names. 2. You are slicing your hex strings incorrectly. 3. Your code is never going to replace any newlines. You may just want to forget about that feature. You do not quite yet understand the difference between a character, its integer code, and the hex string that represents the integer. They are all different: two are strings and one is an integer, and none of them are equal to each other. 4. For some files, you shouldn't remove newlines.
===
1. Your variable names are horrendous.
That's fine if you never want to ask anybody questions. But since every one needs to ask questions, you need to use descriptive variable names that anyone can understand. Your variable names are only slightly better than these:
fname = 'data.txt'
f = open(fname, 'rb')
xxxyxx = f.read()
xxyxxx = len(xxxyxx)
print "Length of file is", xxyxxx, "bytes. "
yxxxxx = 0
while yxxxxx < xxyxxx:
xyxxxx = hex(ord(xxxyxx[yxxxxx]))
xyxxxx = xyxxxx[-2:]
yxxxxx = yxxxxx + 1
xxxxxy = chr(13) + chr(10)
xxxxyx = str(xxxxxy)
xyxxxxx = str(xyxxxx)
xyxxxxx.replace(xxxxyx, ' ')
print xyxxxxx
That program runs fine, but it is impossible to understand.
2. The hex() function produces strings of different lengths.
For instance,
print hex(61)
print hex(15)
--output:--
0x3d
0xf
And taking the slice [-2:] for each of those strings gives you:
3d
xf
See how you got the 'x' in the second one? The slice:
[-2:]
says to go to the end of the string and back up two characters, then grab the rest of the string. Instead of doing that, take the slice starting 3 characters in from the beginning:
[2:]
3. Your code will never replace any newlines.
Suppose your file has these two consecutive characters:
"\r\n"
Now you read in the first character, "\r", and convert it to an integer, ord("\r"), giving you the integer 13. Now you convert that to a string, hex(13), which gives you the string "0xd"
, and you slice off the first two characters giving you:
"d"
Next, this line in your code:
bndtx.replace(entx, ' ')
tries to find every occurrence of the string "\r\n"
in the string "d"
and replace it. There is never going to be any replacement because the replacement string is two characters long and the string "d"
is one character long.
The replacement won't work for "\r\n"
and "0d"
either. But at least now there is a possibility it could work because both strings have two characters. Let's reduce both strings to a common denominator: ascii codes. The ascii code for "\r" is 13, and the ascii code for "\n" is 10. Now what about the string "0d"
? The ascii code for the character "0"
is 48, and the ascii code for the character "d" is 100. Those strings do not have a single character in common. Even this doesn't work:
x = '0d' + '0a'
x.replace("\r\n", " ")
print x
--output:--
'0d0a'
Nor will this:
x = 'd' + 'a'
x.replace("\r\n", " ")
print x
--output:--
da
The bottom line is: converting a character to an integer then to a hex string does not end up giving you the original character--they are just different strings. So if you do this:
char = "a"
code = ord(char)
hex_str = hex(code)
print char.replace(hex_str, " ")
...you can't expect "a" to be replaced by a space. If you examine the output here:
char = "a"
print repr(char)
code = ord(char)
print repr(code)
hex_str = hex(code)
print repr(hex_str)
print repr(
char.replace(hex_str, " ")
)
--output:--
'a'
97
'0x61'
'a'
You can see that 'a' is a string with one character in it, and '0x61'
is a string with 4 characters in it: '0'
, 'x'
, '6'
, and '1'
, and you can never find a four character string inside a one character string.
4) Removing newlines can corrupt the data.
For some files, you do not want to replace newlines. For instance, if you were reading in a .jpg file, which is a file that contains a bunch of integers representing colors in an image, and some colors in the image happened to be represented by the number 13 followed by the number 10, your code would eliminate those colors from the output.
However, if you are writing a program to read only text files, then replacing newlines is fine. But then, different operating systems use different newlines. You are trying to replace Windows newlines(\r\n), which means your program won't work on files created by a Mac or Linux computer, which use \n for newlines. There are easy ways to solve that, but maybe you don't want to worry about that just yet.
I hope all that's not too confusing.
Is it possible to assign a base class object to a derived class reference with an explicit typecast in C#?.
Not only explicit, but also implicit conversions are possible.
C# language doesn't permit such conversion operators, but you can still write them using pure C# and they work. Note that the class which defines the implicit conversion operator (Derived
) and the class which uses the operator (Program
) must be defined in separate assemblies (e.g. the Derived
class is in a library.dll
which is referenced by program.exe
containing the Program
class).
//In library.dll:
public class Base { }
public class Derived {
[System.Runtime.CompilerServices.SpecialName]
public static Derived op_Implicit(Base a) {
return new Derived(a); //Write some Base -> Derived conversion code here
}
[System.Runtime.CompilerServices.SpecialName]
public static Derived op_Explicit(Base a) {
return new Derived(a); //Write some Base -> Derived conversion code here
}
}
//In program.exe:
class Program {
static void Main(string[] args) {
Derived z = new Base(); //Visual Studio can show squiggles here, but it compiles just fine.
}
}
When you reference the library using the Project Reference in Visual Studio, VS shows squiggles when you use the implicit conversion, but it compiles just fine. If you just reference the library.dll
, there are no squiggles.
By default, hibernate framework will immediately return id , when you are trying to save the entity using Save(entity)
method. There is no need to do it explicitly.
In case your primary key is int
you can use below code:
int id=(Integer) session.save(entity);
In case of string use below code:
String str=(String)session.save(entity);
create or replace PROCEDURE PROC_USER_EXP

The following is aimed at beginners to ASP.Net...
A postback originates from the client browser. Usually one of the controls on the page will be manipulated by the user (a button clicked or dropdown changed, etc), and this control will initiate a postback. The state of this control, plus all other controls on the page,(known as the View State) is Posted Back to the web server.
Most commonly the postback causes the web server to create an instance of the code behind class of the page that initiated the postback. This page object is then executed within the normal page lifecycle with a slight difference (see below). If you do not redirect the user specifically to another page somewhere during the page lifecycle, the final result of the postback will be the same page displayed to the user again, and then another postback could happen, and so on.
The web application is running on the web server. In order to process the user’s response, cause the application state to change, or move to a different page, you need to get some code to execute on the web server. The only way to achieve this is to collect up all the information that the user is currently working on and send it all back to the server.
Some things for a beginner to note are...

Well, tempnam() will do it for you.

but that creates an entirely new name.
To sanitize an existing string just restrict what your users can enter and make it letters, numbers, period, hyphen and underscore then sanitize with a simple regex. Check what characters need to be escaped or you could get false positives.
$sanitized = preg_replace('/[^a-zA-Z0-9\-\._]/','', $filename);
Install Chocolatey. Then run:
choco install nodejs.install -version 6.3.0

Since you've already stashed your changes, all you need is this one-liner:
git stash branch <branchname> [<stash>]
From the docs (https://www.kernel.org/pub/software/scm/git/docs/git-stash.html):
Creates and checks out a new branch named <branchname> starting from the commit at which the <stash> was originally created, applies the changes recorded in <stash> to the new working tree and index. If that succeeds, and <stash> is a reference of the form stash@{<revision>}, it then drops the <stash>. When no <stash> is given, applies the latest one.
This is useful if the branch on which you ran git stash save has changed enough that git stash apply fails due to conflicts. Since the stash is applied on top of the commit that was HEAD at the time git stash was run, it restores the originally stashed state with no conflicts.
Answer above is missing an example which might not be obvious (it wasn't to me).

If you don't want to use absolute positioning and all that jazz, here's a fix I like to use:
your html:
<body>
<div id="header"></div>
<div id="wrapper"></div>
</body>
your css:
body {
height:100%;
padding-top:60px;
}
#header {
margin-top:60px;
height:60px;
}
#wrapper {
height:100%;
}
In the particular case where you know the number of positions that you want to remove from the dataframe column, you can use string indexing inside a lambda function to get rid of that parts:
Last character:
data['result'] = data['result'].map(lambda x: str(x)[:-1])
First two characters:
data['result'] = data['result'].map(lambda x: str(x)[2:])
In my case, it's a typo caused this issue:
<VirtualHost *.8080>
should be
<VirtualHost *:8080>
As Toan suggests, a simple hack would be to just select the rows first, and then select the columns over that.
>>> a[[0,1,3], :] # Returns the rows you want
array([[ 0, 1, 2, 3],
[ 4, 5, 6, 7],
[12, 13, 14, 15]])
>>> a[[0,1,3], :][:, [0,2]] # Selects the columns you want as well
array([[ 0, 2],
[ 4, 6],
[12, 14]])
np.ix_
I recently discovered that numpy gives you an in-built one-liner to doing exactly what @Jaime suggested, but without having to use broadcasting syntax (which suffers from lack of readability). From the docs:
Using ix_ one can quickly construct index arrays that will index the cross product.
a[np.ix_([1,3],[2,5])]
returns the array[[a[1,2] a[1,5]], [a[3,2] a[3,5]]]
.
So you use it like this:
>>> a = np.arange(20).reshape((5,4))
>>> a[np.ix_([0,1,3], [0,2])]
array([[ 0, 2],
[ 4, 6],
[12, 14]])
And the way it works is that it takes care of aligning arrays the way Jaime suggested, so that broadcasting happens properly:
>>> np.ix_([0,1,3], [0,2])
(array([[0],
[1],
[3]]), array([[0, 2]]))
Also, as MikeC says in a comment, np.ix_
has the advantage of returning a view, which my first (pre-edit) answer did not. This means you can now assign to the indexed array:
>>> a[np.ix_([0,1,3], [0,2])] = -1
>>> a
array([[-1, 1, -1, 3],
[-1, 5, -1, 7],
[ 8, 9, 10, 11],
[-1, 13, -1, 15],
[16, 17, 18, 19]])
Yes, it is possible to run PowerShell through the run window. However, it would be burdensome and you will need to enter in the password for computer. This is similar to how you will need to set up when you run cmd:
runas /user:(ComputerName)\(local admin) powershell.exe
So a basic example would be:
runas /user:MyLaptop\[email protected] powershell.exe
You can find more information on this subject in Runas.
However, you could also do one more thing :
then your system will execute the elevated powershell.
If you wrap the container in a dummy P
tag you will get the container HTML also.
All you need to do is
var x = $('#container').wrap('<p/>').parent().html();
Check working example at http://jsfiddle.net/rzfPP/68/
To unwrap()
the <p>
tag when done, you can add
$('#container').unwrap();
This answer should be updated to reflect new web standards (HTML5).
This:
<a tabindex="0">This represents a placeholder hyperlink</a>
... is valid HTML5. The tabindex attribute makes it keyboard focusable like normal hyperlinks. You might as well use the span
element for this as mentioned previously, but I find using the a
element more elegant.
See: https://w3c.github.io/html-reference/a.html
and: https://html.spec.whatwg.org/multipage/links.html#attr-hyperlink-href
Since many of the answers required API 26 support and my min API was 23, I solved it by below code :
import org.joda.time.Days
LocalDate startDate = Something
LocalDate endDate = Something
// The difference would be exclusive of both dates,
// so in most of use cases we may need to increment it by 1
Days.daysBetween(startDate, endDate).days
jQuery is simply supporting the way CSS is written.
Also, it ensures that no matter how a browser returns a value, it will be understood
jQuery can equally interpret the CSS and DOM formatting of multiple-word properties. For example, jQuery understands and returns the correct value for both .css('background-color') and .css('backgroundColor').
This supplemental answer shows the effect of changing the line spacing.
You can set the multiplier and/or extra spacing with
textView.setLineSpacing(float add, float mult)
Or you can get the values with
int lineHeight = textView.getLineHeight();
float add = tvSampleText.getLineSpacingExtra(); // API 16+
float mult = tvSampleText.getLineSpacingMultiplier(); // API 16+
where the formula is
lineHeight = fontMetricsLineHeight * mult + add
The default multiplier is 1
and the default extra spacing is 0
.
There are several approaches:
You can normally see assembly code while debugging C++ in visual studio (and eclipse too). For this in Visual Studio put a breakpoint on code in question and when debugger hits it rigth click and find "Go To Assembly" ( or press CTRL+ALT+D )
Second approach is to generate assembly listings while compiling. For this go to project settings -> C/C++ -> Output Files -> ASM List Location and fill in file name. Also select "Assembly Output" to "Assembly With Source Code".
Compile the program and use any third-party debugger. You can use OllyDbg or WinDbg for this. Also you can use IDA (interactive disassembler). But this is hardcore way of doing it.
Please do yourself a favor and just hit the easy button:
download Web Inspector (Open Source) from the Play store.
A CAVEAT: ATTOW, console output does not accept rest params! I.e. if you have something like this:
console.log('one', 'two', 'three');
you will only see
one
logged to the console. You'll need to manually wrap the params in an Array and join, like so:
console.log([ 'one', 'two', 'three' ].join(' '));
to see the expected output.
But the app is open source! A patch may be imminent! The patcher could even be you!
here's the best of both worlds.
I also "like" underscores, besides all your positive points about them, there is also a certain old-school style to them.
So what I do is use underscores and simply add a small rewrite rule to your Apache's .htaccess file to re-write all underscores to hyphens.

If you're using SQL Server 2005 or later (and the tags for your question indicate SQL Server 2008), you can use ranking functions to return the duplicate records after the first one if using joins is less desirable or impractical for some reason. The following example shows this in action, where it also works with null values in the columns examined.
create table Table1 (
Field1 int,
Field2 int,
Field3 int,
Field4 int
)
insert Table1
values (1,1,1,1)
, (1,1,1,2)
, (1,1,1,3)
, (2,2,2,1)
, (3,3,3,1)
, (3,3,3,2)
, (null, null, 2, 1)
, (null, null, 2, 3)
select *
from (select Field1
, Field2
, Field3
, Field4
, row_number() over (partition by Field1
, Field2
, Field3
order by Field4) as occurrence
from Table1) x
where occurrence > 1
Notice after running this example that the first record out of every "group" is excluded, and that records with null values are handled properly.
If you don't have a column available to order the records within a group, you can use the partition-by columns as the order-by columns.
You can use a while loop to delete item/items matching ChunkID. Here is my suggestion:
public void DeleteChunk(int ChunkID)
{
int i = 0;
while (i < ChunkList.Count)
{
Chunk currentChunk = ChunkList[i];
if (currentChunk.UniqueID == ChunkID) {
ChunkList.RemoveAt(i);
}
else {
i++;
}
}
}
Ok, but what about common in almost every language way items[len(items) - 1]
? This is IMO the easiest way to get last element, because it does not require anything pythonic knowledge.
In my case I have succeed with the following solution for converting field ClockInTime from ClockTime collection from string to Date type:
db.ClockTime.find().forEach(function(doc) {
doc.ClockInTime=new Date(doc.ClockInTime);
db.ClockTime.save(doc);
})
Try using this..
[0-9]{2}[/][0-9]{2}[/][0-9]{4}$
this should work with this pattern DD/DD/DDDD
where D is any digit (0-9)
this tutorial works for me
ALTER TABLE table_name
ADD CONSTRAINT constraint_name UNIQUE (column1, column2, ... column_n);

In CPython, range(...).__contains__
(a method wrapper) will eventually delegate to a simple calculation which checks if the value can possibly be in the range. The reason for the speed here is we're using mathematical reasoning about the bounds, rather than a direct iteration of the range object. To explain the logic used:
start
and stop
, andFor example, 994
is in range(4, 1000, 2)
because:
4 <= 994 < 1000
, and(994 - 4) % 2 == 0
.The full C code is included below, which is a bit more verbose because of memory management and reference counting details, but the basic idea is there:
static int
range_contains_long(rangeobject *r, PyObject *ob)
{
int cmp1, cmp2, cmp3;
PyObject *tmp1 = NULL;
PyObject *tmp2 = NULL;
PyObject *zero = NULL;
int result = -1;
zero = PyLong_FromLong(0);
if (zero == NULL) /* MemoryError in int(0) */
goto end;
/* Check if the value can possibly be in the range. */
cmp1 = PyObject_RichCompareBool(r->step, zero, Py_GT);
if (cmp1 == -1)
goto end;
if (cmp1 == 1) { /* positive steps: start <= ob < stop */
cmp2 = PyObject_RichCompareBool(r->start, ob, Py_LE);
cmp3 = PyObject_RichCompareBool(ob, r->stop, Py_LT);
}
else { /* negative steps: stop < ob <= start */
cmp2 = PyObject_RichCompareBool(ob, r->start, Py_LE);
cmp3 = PyObject_RichCompareBool(r->stop, ob, Py_LT);
}
if (cmp2 == -1 || cmp3 == -1) /* TypeError */
goto end;
if (cmp2 == 0 || cmp3 == 0) { /* ob outside of range */
result = 0;
goto end;
}
/* Check that the stride does not invalidate ob's membership. */
tmp1 = PyNumber_Subtract(ob, r->start);
if (tmp1 == NULL)
goto end;
tmp2 = PyNumber_Remainder(tmp1, r->step);
if (tmp2 == NULL)
goto end;
/* result = ((int(ob) - start) % step) == 0 */
result = PyObject_RichCompareBool(tmp2, zero, Py_EQ);
end:
Py_XDECREF(tmp1);
Py_XDECREF(tmp2);
Py_XDECREF(zero);
return result;
}
static int
range_contains(rangeobject *r, PyObject *ob)
{
if (PyLong_CheckExact(ob) || PyBool_Check(ob))
return range_contains_long(r, ob);
return (int)_PySequence_IterSearch((PyObject*)r, ob,
PY_ITERSEARCH_CONTAINS);
}
The "meat" of the idea is mentioned in the line:
/* result = ((int(ob) - start) % step) == 0 */
As a final note - look at the range_contains
function at the bottom of the code snippet. If the exact type check fails then we don't use the clever algorithm described, instead falling back to a dumb iteration search of the range using _PySequence_IterSearch
! You can check this behaviour in the interpreter (I'm using v3.5.0 here):
>>> x, r = 1000000000000000, range(1000000000000001)
>>> class MyInt(int):
... pass
...
>>> x_ = MyInt(x)
>>> x in r # calculates immediately :)
True
>>> x_ in r # iterates for ages.. :(

@martinho as a newbie using Flask and Python myself, I think the previous answers here took for granted that you had a good understanding of the fundamentals. In case you or other viewers don't know the fundamentals, I'll give more context to understand the answer...
... the request.args
is bringing a "dictionary" object for you. The "dictionary" object is similar to other collection-type of objects in Python, in that it can store many elements in one single object. Therefore the answer to your question
And how many parameters
request.args.get()
takes.
It will take only one object, a "dictionary" type of object (as stated in the previous answers). This "dictionary" object, however, can have as many elements as needed... (dictionaries have paired elements called Key, Value).
Other collection-type of objects besides "dictionaries", would be "tuple", and "list"... you can run a google search on those and "data structures" in order to learn other Python fundamentals. This answer is based Python; I don't have an idea if the same applies to other programming languages.
To adjust the length of the samples:
set key samplen X
(default is 4)
To adjust the vertical spacing of the samples:
set key spacing X
(default is 1.25)
and (for completeness), to adjust the fontsize:
set key font "<face>,<size>"
(default depends on the terminal)
And of course, all these can be combined into one line:
set key samplen 2 spacing .5 font ",8"
Note that you can also change the position of the key using set key at <position>
or any one of the pre-defined positions (which I'll just defer to help key
at this point)
I had this problem inconsistently between different platforms, as I got JSON as String from Mapper and did the writing myself. Sometimes it went into file as ansi and other times correctly as UTF8. I switched to
mapper.writeValue(file, data);
letting Mapper do the file operations, and it started working fine.
I would not recommend utilizing the Grid system in this instance, as much as simply adding an increased padding for each <h2>
. That being said, the way you would achieve this using col-*-offset-*
would be as follows:
<div class="jumbotron">
<div class="container">
<div class="row">
<div class="col-md-12">
<h2>One</h2>
</div>
<div class="col-md-11 col-md-offset-1">
<h2>Two</h2>
</div>
<div class="col-md-10 col-md-offset-2">
<h2>Three</h2>
</div>
</div>
</div>
</div>
Essentially the first line must span the entire row (so -12). The second line must be offset by 1 column, so you offset by 1 and give it a total width of 11 columns (11+1 = 12) and so forth. Your offset is always enough to ensure that the total column count equals 12.
Goto my blog : retrofit with kotlin
the link below explains everything step by step.
http://loopj.com/android-async-http/
Here are sample apps:
Create a class :
public class HttpUtils {
private static final String BASE_URL = "http://api.twitter.com/1/";
private static AsyncHttpClient client = new AsyncHttpClient();
public static void get(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
client.get(getAbsoluteUrl(url), params, responseHandler);
}
public static void post(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
client.post(getAbsoluteUrl(url), params, responseHandler);
}
public static void getByUrl(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
client.get(url, params, responseHandler);
}
public static void postByUrl(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
client.post(url, params, responseHandler);
}
private static String getAbsoluteUrl(String relativeUrl) {
return BASE_URL + relativeUrl;
}
}
Call Method :
RequestParams rp = new RequestParams();
rp.add("username", "aaa"); rp.add("password", "aaa@123");
HttpUtils.post(AppConstant.URL_FEED, rp, new JsonHttpResponseHandler() {
@Override
public void onSuccess(int statusCode, Header[] headers, JSONObject response) {
// If the response is JSONObject instead of expected JSONArray
Log.d("asd", "---------------- this is response : " + response);
try {
JSONObject serverResp = new JSONObject(response.toString());
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
@Override
public void onSuccess(int statusCode, Header[] headers, JSONArray timeline) {
// Pull out the first event on the public timeline
}
});
Please grant internet permission in your manifest file.
<uses-permission android:name="android.permission.INTERNET" />
you can add compile 'com.loopj.android:android-async-http:1.4.9'
for Header[]
and compile 'org.json:json:20160212'
for JSONObject
in build.gradle file if required.
You don't need to learn JPA. You can use my easy-criteria for JPA2 (https://sourceforge.net/projects/easy-criteria/files/). Here is the example
CriteriaComposer<Pet> petCriteria CriteriaComposer.from(Pet.class).
where(Pet_.type, EQUAL, "Cat").join(Pet_.owner).where(Ower_.name,EQUAL, "foo");
List<Pet> result = CriteriaProcessor.findAllEntiry(petCriteria);
OR
List<Tuple> result = CriteriaProcessor.findAllTuple(petCriteria);
You don't have to add any extra javascript to what's already included with bootstraps collapse option. Instead simply include data-toggle and data-target selectors on your menu list items just as you do with your navbar-toggle button. So for your Products menu item it would look like this
<li><a href="#Products" data-toggle="collapse" data-target=".navbar-collapse">Products</a></li>
Then you would need to repeat the data-toggle and data-target selectors for each menu item
EDIT!!! In order to fix overflow issues and flickering on this fix I'm adding some more code that will fix this and still not have any extra javascript. Here is the new code:
<li><a href="#products" class="hidden-xs">Products</a></li>
<li><a href="#products" class="visible-xs" data-toggle="collapse" data-target=".navbar-collapse">Products</a></li>
Here it is at work http://jsfiddle.net/jaketaylor/84mqazgq/
This will make your toggle and target selectors specific to screen size and eliminate glitches on the larger menu. If anyone is still having issues with glitches please let me know and I'll find a fix. Thanks
EDIT: In the bootstrap v4.1.3 I couldnt use visible/hidden classes. Instead of hidden-xs
use d-none d-sm-block
and instead of visible-xs
use d-block d-sm-none
.
Yes you can access them. You should declare them in 'public space' (outside any functions) as:
var globalvar1 = 'value';
You can access them later on, also in other files.

Its not exactly what you were looking for, but may be it can help you somewhere.
./
refers to the current working directory, except in the require()
function. When using require()
, it translates ./
to the directory of the current file called. __dirname
is always the directory of the current file.
For example, with the following file structure
/home/user/dir/files/config.json
{
"hello": "world"
}
/home/user/dir/files/somefile.txt
text file
/home/user/dir/dir.js
var fs = require('fs');
console.log(require('./files/config.json'));
console.log(fs.readFileSync('./files/somefile.txt', 'utf8'));
If I cd
into /home/user/dir
and run node dir.js
I will get
{ hello: 'world' }
text file
But when I run the same script from /home/user/
I get
{ hello: 'world' }
Error: ENOENT, no such file or directory './files/somefile.txt'
at Object.openSync (fs.js:228:18)
at Object.readFileSync (fs.js:119:15)
at Object.<anonymous> (/home/user/dir/dir.js:4:16)
at Module._compile (module.js:432:26)
at Object..js (module.js:450:10)
at Module.load (module.js:351:31)
at Function._load (module.js:310:12)
at Array.0 (module.js:470:10)
at EventEmitter._tickCallback (node.js:192:40)
Using ./
worked with require
but not for fs.readFileSync
. That's because for fs.readFileSync
, ./
translates into the cwd (in this case /home/user/
). And /home/user/files/somefile.txt
does not exist.
To get all the differences between two tables, you can use like me this SQL request :
SELECT 'TABLE1-ONLY' AS SRC, T1.*
FROM (
SELECT * FROM Table1
EXCEPT
SELECT * FROM Table2
) AS T1
UNION ALL
SELECT 'TABLE2-ONLY' AS SRC, T2.*
FROM (
SELECT * FROM Table2
EXCEPT
SELECT * FROM Table1
) AS T2
;
The best solution is to acknowledge the asynchronous nature of the download and design for it.
In other words, decide what your application should look like while the data is downloading. Have the page constructor set up that view, and start the download. When the download completes update the page to display the data.
I have a blog post on asynchronous constructors that you may find useful. Also, some MSDN articles; one on asynchronous data-binding (if you're using MVVM) and another on asynchronous best practices (i.e., you should avoid async void
).
The default Apache root folder (localhost/) is /Library/WebServer/Documents
Also, make sure you have the PHP5 module loaded in /etc/apache2/httpd.conf
LoadModule php5_module libexec/apache2/libphp5.so
Try this, if it helps you
values = ['1', '2', '3']
with open("file.txt", "w") as output:
output.write(str(values))
The calculated column trick is widely known as a "nullbuster"; my notes credit Steve Kass:
CREATE TABLE dupNulls (
pk int identity(1,1) primary key,
X int NULL,
nullbuster as (case when X is null then pk else 0 end),
CONSTRAINT dupNulls_uqX UNIQUE (X,nullbuster)
)

If you have direct access to the remote repo, you could always use:
git reset --soft HEAD^
This works since there is no attempt to modify the non-existent working directory. For more details please see the original answer:
How can I uncommit the last commit in a git bare repository?
UPDATE: As Brad Parks wrote in his comment there is a much better and easier solution with only one line of JS code:
run
setTimeout(function(){debugger;},5000);
, then go show your element and wait until it breaks into the Debugger
Original answer:
I just had the same problem, and I think I found an "universal" solution. (assuming the site uses jQuery)
Hope it helps someone!
<body>
and click "Edit as HTML"<body>
then press Ctrl+Enter: <div id="debugFreeze" data-rand="0"></div>
setTimeout(function(){$("#debugFreeze").attr("data-rand",Math.random())},5000);
Of course you can modify the javascript and the timing, if you get the idea.
It's also much more better to not modify the app/config/database.php
file itself... otherwise modify .env
file and put your DB info there. (.env
file is available in Laravel 5, not sure if it was there in previous versions...)
NOTE: Of course you should have already set mysql
as your default database connection in the app/config/database.php
file.
I faced a similar issue and the root cause was that GAC had 2 oracle.dataaccess versions i.e. v4.0_4.112.2.0 and v4.0_4.112.4.0 . My application was referring to v4.0_4.112.2.0 , so when I removed v4.0_4.112.4.0 from GAC, it worked fine.
GAC path : C:\Windows\Microsoft.NET\assembly\GAC_64\Oracle.DataAccess
To remove a version, one can simply delete the corresponding folder from GAC.
You can pass values by using the below .
@Html.ActionLink("About", "About", "Home",new { name = ViewBag.Name }, htmlAttributes:null )
Controller:
public ActionResult About(string name)
{
ViewBag.Message = "Your application description page.";
ViewBag.NameTransfer = name;
return View();
}
And the URL looks like
http://localhost:50297/Home/About?name=My%20Name%20is%20Vijay
