It means you have a null reference somewhere in there. Can you debug the app and stop the debugger when it gets here and investigate? Probably img1
is null or ConfigurationManager.AppSettings.Get("Url")
is returning null.
Just do
if (Attachment != null && Attachment.Length > 0)
From && Operator
The conditional-AND operator (&&) performs a logical-AND of its bool operands, but only evaluates its second operand if necessary.
1) To remove white space everywhere:
df.columns = df.columns.str.replace(' ', '')
2) To remove white space at the beginning of string:
df.columns = df.columns.str.lstrip()
3) To remove white space at the end of string:
df.columns = df.columns.str.rstrip()
4) To remove white space at both ends:
df.columns = df.columns.str.strip()
5) To replace white space everywhere
df.columns = df.columns.str.replace(' ', '_')
6) To replace white space at the beginning:
df.columns = df.columns.str.replace('^ +', '_')
7) To replace white space at the end:
df.columns = df.columns.str.replace(' +$', '_')
8) To replace white space at both ends:
df.columns = df.columns.str.replace('^ +| +$', '_')
All above applies to a specific column as well, assume you have a column named col
, then just do:
df[col] = df[col].str.strip() # or .replace as above
Using dplyr
and tidyr
:
library(dplyr)
library(tidyr)
df <- as_data_frame(mat) %>% # convert the matrix to a data frame
gather(name, val, C_0:C_1) %>% # convert the data frame from wide to long
select(name, time, val) # reorder the columns
df
# A tibble: 6 x 3
name time val
<chr> <dbl> <dbl>
1 C_0 0.0 0.1
2 C_0 0.5 0.2
3 C_0 1.0 0.3
4 C_1 0.0 0.3
5 C_1 0.5 0.4
6 C_1 1.0 0.5
Well you can use lodash to write a code which will be less verbose
Approach 1:Nested Approach
let array =
[
{"name":"Joe", "age":17},
{"name":"Bob", "age":17},
{"name":"Carl", "age": 35}
]
let result = _.uniq(_.map(array,item=>item.age))
Approach 2: Method Chaining or Cascading method
let array =
[
{"name":"Joe", "age":17},
{"name":"Bob", "age":17},
{"name":"Carl", "age": 35}
]
let result = _.chain(array).map(item=>item.age).uniq().value()
You can read about lodash's uniq() method from https://lodash.com/docs/4.17.15#uniq
you can also just add it to the command option eg.
command: bash -c "sleep 5; start.sh"
https://github.com/docker/compose/issues/374#issuecomment-156546513
to wait on a port you can also use something like this
command: bash -c "while ! curl -s rabbitmq:5672 > /dev/null; do echo waiting for xxx; sleep 3; done; start.sh"
to increment the waiting time you can hack a bit more:
command: bash -c "for i in {1..100} ; do if ! curl -s rabbitmq:5672 > /dev/null ; then echo waiting on rabbitmq for $i seconds; sleep $i; fi; done; start.sh"
This is caused when your request response is not received in given time(by timeout
request module option).
Basically to catch that error first, you need to register a handler on error
, so the unhandled error won't be thrown anymore: out.on('error', function (err) { /* handle errors here */ })
. Some more explanation here.
In the handler you can check if the error is ETIMEDOUT and apply your own logic: if (err.message.code === 'ETIMEDOUT') { /* apply logic */ }
.
If you want to request for the file again, I suggest using node-retry or node-backoff modules. It makes things much simpler.
If you want to wait longer, you can set timeout
option of request yourself. You can set it to 0 for no timeout.
Since you are not worried about IE, why not just use css transitions to provide the animation and jQuery to change the classes. Live example: http://jsfiddle.net/tw16/JfK6N/
#someDiv{
-webkit-transition: all 0.5s ease;
-moz-transition: all 0.5s ease;
-o-transition: all 0.5s ease;
transition: all 0.5s ease;
}
I was having the same issue. Logs weren't giving me any clues either. So I scaled down and scaled back up the dynos. This solved the problem for me:
heroku ps:scale web=0
Waited a few seconds...
heroku ps:scale web=1
Relaxing your requirement to work on IE6 and legacy browsers you can use ::before and display: inline-block
div
{
display: inline-block;
position: relative;
}
div::before
{
content: "";
display: block;
position: absolute;
z-index: -1;
width: 100%;
height: 100%;
background:red;
opacity: .2;
}
Demo at http://jsfiddle.net/KVyFH/172/ ?
It will work on any modern browser
This answer owes much to Klemen Slavic. I would have just commented on the accepted answer but I don't have enough rep yet :(
You could also add a git alias to find the stash ref and use it in other aliases for show, apply, drop, etc.
[alias]
sgrep = "!f() { ref=$(git --no-pager stash list | grep "$1" | cut -d: -f1 | head -n1); echo ${ref:-<no_match>}; }; f"
sshow = "!f() { git stash show $(git sgrep "$1") -p; }; f"
sapply = "!f() { git stash apply $(git sgrep "$1"); }; f"
sdrop = "!f() { git stash drop $(git sgrep "$1"); }; f"
Note that the reason for the ref=$( ... ); echo ${ref:-<no_match>};
pattern is so a blank string is not returned which would cause sshow, sapply and sdrop to target the latest stash instead of fail as one would expect.
If you're using ASP.NET Core MVC and need to handle the square brackets (rather than use the jQuery "traditional" option), the only option I've found is to manually build the IEnumerable
in the contoller method.
string arrayKey = "p[]=";
var pArray = HttpContext.Request.QueryString.Value
.Split('&')
.Where(s => s.Contains(arrayKey))
.Select(s => s.Substring(arrayKey.Length));
ok , i've solved it by creating a handler on the onCreate of the service , and calling the gps functions through there .
The code is as simple as this:
final handler=new Handler(Looper.getMainLooper());
And then to force running things on the UI, I call post
on it.
When running the command: cordova plugin remove <PLUGIN NAME>
, ensure that you do not add the version number to the plugin name. Just plain plugin name, for example:
cordova plugin remove cordova.plugin_name
and not:
cordova plugin remove cordova.plugin_name 0.01
or
cordova plugin remove "cordova.plugin_name 0.01"
In case there is a privilege issue, run with sudo if you are on a *nix system, for example:
sudo cordova plugin remove cordova.plugin_name
Then you may add --save to remove it from the config.xml file. For example:
cordova plugin remove cordova.plugin_name --save
java.util.Date.from(localDate.atStartOfDay().atZone(ZoneId.systemDefault()).toInstant());
If your spring-context.xml and my.config files are in different jars then you will need to use classpath*:my.config
?
More info here
Also, make sure you are using resource.getInputStream()
not resource.getFile()
when loading from inside a jar file.
Actually super easy with management plugin and policies:
Goto Management Console (localhost:15672)
Goto Admin tab
Goto Policies tab(on the right side)
Add Policy
Fill Fields
Save
Checkout Queues tab again
All Queues must be deleted
And don't forget to remove policy!!!!!!.
You need to add app.coffee
to staging.
Do git add app.coffee
and then you will be able to apply your stash (after that commit and push).
If not HTML
, then UTF-8
is not recommended. koi8-r
and windows-1251
only without problems. So use html mail.
$headers['Content-Type']='text/html; charset=UTF-8';
$body='<html><head><meta charset="UTF-8"><title>ESP Notufy - ESP ?????????</title></head><body>'.$text.'</body></html>';
$mail_object=& Mail::factory('smtp',
array ('host' => $host,
'auth' => true,
'username' => $username,
'password' => $password));
$mail_object->send($recipents, $headers, $body);
}
Why use GROUP BY at all?
SELECT player_name, player_salary, player_salary*1.1 AS NewSalary
FROM players
ORDER BY player_salary DESC
For python3.5, you can use the following code:
import urllib.request
res = urllib.request.urlopen(starturl)
finalurl = res.geturl()
print(finalurl)
use arrayOf, arrayOfNulls, emptyArray
var colors_1: Array<String> = arrayOf("green", "red", "blue")
var colors_2: Array<String?> = arrayOfNulls(3)
var colors_3: Array<String> = emptyArray()
sentence.sub! 'Robert', 'Joe'
Won't cause an exception if the replaced word isn't in the sentence (the []=
variant will).
The above replaces only the first instance of "Robert".
To replace all instances use gsub
/gsub!
(ie. "global substitution"):
sentence.gsub! 'Robert', 'Joe'
The above will replace all instances of Robert with Joe.
mysqli_select_db()
should have 2 parameters, the connection link and the database name -
mysqli_select_db($con, 'phpcadet') or die(mysqli_error($con));
Using mysqli_error
in the die statement will tell you exactly what is wrong as opposed to a generic error message.
Use Method to Serialize and Deserialize Collection object from memory. This works on Collection Data Types. This Method will Serialize collection of any type to a byte stream. Create a Seperate Class SerilizeDeserialize
and add following two methods:
public class SerilizeDeserialize
{
// Serialize collection of any type to a byte stream
public static byte[] Serialize<T>(T obj)
{
using (MemoryStream memStream = new MemoryStream())
{
BinaryFormatter binSerializer = new BinaryFormatter();
binSerializer.Serialize(memStream, obj);
return memStream.ToArray();
}
}
// DSerialize collection of any type to a byte stream
public static T Deserialize<T>(byte[] serializedObj)
{
T obj = default(T);
using (MemoryStream memStream = new MemoryStream(serializedObj))
{
BinaryFormatter binSerializer = new BinaryFormatter();
obj = (T)binSerializer.Deserialize(memStream);
}
return obj;
}
}
How To use these method in your Class:
ArrayList arrayListMem = new ArrayList() { "One", "Two", "Three", "Four", "Five", "Six", "Seven" };
Console.WriteLine("Serializing to Memory : arrayListMem");
byte[] stream = SerilizeDeserialize.Serialize(arrayListMem);
ArrayList arrayListMemDes = new ArrayList();
arrayListMemDes = SerilizeDeserialize.Deserialize<ArrayList>(stream);
Console.WriteLine("DSerializing From Memory : arrayListMemDes");
foreach (var item in arrayListMemDes)
{
Console.WriteLine(item);
}
I finally got it:
ObjectMapper objectMapper = new ObjectMapper();
TypeFactory typeFactory = objectMapper.getTypeFactory();
List<SomeClass> someClassList = objectMapper.readValue(jsonString, typeFactory.constructCollectionType(List.class, SomeClass.class));
It seems that you are using the 64-bit version of the tool to install a 32-bit/x86 architecture application. Look for the 32-bit version of the tool here:
C:\Windows\Microsoft.NET\Framework\v4.0.30319
and it should install your 32-bit application just fine.
Suspended. The session is waiting for an event, such as I/O, to complete.
You'll need to add a reference to System.Configuration

You should definitely be using the ConfigurationManager

It's just a colon delimited key-value.
ETag: "xyzzy"
It can be any type of text data - I generally include a JSON string with the identifier of the item created. The ease of testing alone makes including it worthwhile.
ETag: "{ id: 1234, uri: 'http://domain.com/comments/1234', type: 'comment' }"
In this example, the identifier, the uri, and type of the created item are the "resource characteristics and location".
If you're using css modules this is what worked for me.
const [condition, setCondition] = useState(false);
\\ toggle condition
return (
<span className={`${styles.always} ${(condition ? styles.sometimes : '')`}>

)
I wrote a drawable lib to custom round corner position, it looks like this:

Building off of @gnovice's answer, you can actually create filled plots with shading only in the area between the two curves. Just use fill
in conjunction with fliplr
.
Example:
x=0:0.01:2*pi; %#initialize x array
y1=sin(x); %#create first curve
y2=sin(x)+.5; %#create second curve
X=[x,fliplr(x)]; %#create continuous x value array for plotting
Y=[y1,fliplr(y2)]; %#create y values for out and then back
fill(X,Y,'b'); %#plot filled area
By flipping the x array and concatenating it with the original, you're going out, down, back, and then up to close both arrays in a complete, many-many-many-sided polygon.
Not sure if this helps but for me, many times I reference a DLL (which automatically adds it to the bin folder of course). However that DLL might need additional DLLs (depending on what functions I'm using). I do NOT want to reference those in my Project because they just simply need to end up in the same folder as the DLL I am actually using.
I accomplish this in Visual Studio by "Adding an existing file". You should be able to add it anywhere except the Add_data folder. personally I just add it to the root.
Then change the properties of that file to ...
Build Action = None (having this set to something like Content actually copies the "root" version to the root, plus a copy in the Bin).
Copy to output folder = Copy if Newer (Basically puts it in the BIN folder only if it is missing, but doesn't do it after that)
When I publish.. my added DLL's only exists in the BIN folder and nowhere else in the Publish location (which is what I want).
Ok, I think I have a pretty cool solution.
Let's say you have file a
and file b
.
You have a def
or a class
in file b
that you want to use in module a
, but you have something else, either a def
, class
, or variable from file a
that you need in your definition or class in file b
.
What you can do is, at the bottom of file a
, after calling the function or class in file a
that is needed in file b
, but before calling the function or class from file b
that you need for file a
, say import b
Then, and here is the key part, in all of the definitions or classes in file b
that need the def
or class
from file a
(let's call it CLASS
), you say from a import CLASS
This works because you can import file b
without Python executing any of the import statements in file b
, and thus you elude any circular imports.
For example:
class A(object):
def __init__(self, name):
self.name = name
CLASS = A("me")
import b
go = B(6)
go.dostuff
class B(object):
def __init__(self, number):
self.number = number
def dostuff(self):
from a import CLASS
print "Hello " + CLASS.name + ", " + str(number) + " is an interesting number."
Voila.
Try $(this).load("/file_name.html");
. This method targets a local file.
You can also target remote files (on another domain) take a look at: http://en.wikipedia.org/wiki/Same_origin_policy
And multiple concatenation:
from django import template
register = template.Library()
@register.simple_tag
def concat_all(*args):
"""concatenate all args"""
return ''.join(map(str, args))
And in Template:
{% concat_all 'x' 'y' another_var as string_result %}
concatenated string: {{ string_result }}
It really depends on your use-case.
Comparing 0MQ with ActiveMQ or RabbitMQ is not fair. ActiveMQ and RabbitMQ are Messaging Systems wich require installation and administration. They offer featurewise a lot more than ZeroMQ. They have real persistent Queues, Support for transactions etc.
ZeroMQ is a lightweight message orientated socket implementation. It is also suitable for in-process asynchronous programming. It is possible to run a "Enterprise Messaging System" over ZeroMQ, but you would have to implement a lot on your own.
So:
ActiveMQ, RabbitMQ, Websphere MQ & MSMQ are "Enterprise Message Queues"
ZeroMQ is a message orientated IPC Library.
http://www.w3.org/TR/html4/interact/forms.html#h-17.5
Buttons created with the BUTTON element function just like buttons created with the INPUT element, but they offer richer rendering possibilities: the BUTTON element may have content. For example, a BUTTON element that contains an image functions like and may resemble an INPUT element whose type is set to "image", but the BUTTON element type allows content.
So for functionality only they're interchangeable!
(Don't forget, type="submit"
is the default with button
, so leave it off!)
While the accepted answer is technically correct, a more practical approach, if possible, is to just strip whitespace out of both the regular expression and the search string.
If you want to search for "my cats", instead of:
myString.match(/m\s*y\s*c\s*a\*st\s*s\s*/g)
Just do:
myString.replace(/\s*/g,"").match(/mycats/g)
Warning: You can't automate this on the regular expression by just replacing all spaces with empty strings because they may occur in a negation or otherwise make your regular expression invalid.
JSONObject jsonObj = new JSONObject(jsonString);
JSONArray jArray = jsonObj.getJSONArray("data");

String name=jObj.optString("name");
JSONArray ingredientArray = jObj.getJSONArray("Ingredients");
int size = ingredientArray.length();
ArrayList<String> Ingredients = new ArrayList<>();
for(int j=0; j<size; j++)
{
JSONObject json = ja.getJSONObject(j);
Ingredients.add(json.optString("name"));
}

The blink
element is being abandoned by browsers: Firefox supported it up to version 22, and Opera up to version 12.
The HTML5 CR, which is the first draft specification that mentions blink
, declares it as “obsolete” but describes (in the Rendering section) its “expected rendering” with the rule
blink { text-decoration: blink; }
and recommends that the element be replaced by the use of CSS. There are actually several alternative ways of emulating blink
in CSS and JavaScript, but the rule mentioned is the most straightforward one: the value blink
for text-decoration
was defined specifically to provide a CSS counterpart to the blink
element. However, support to it seems to be as limited as for the blink
element.
If you really want to make content blink in a cross-browser way, you can use e.g. simple JavaScript code that changes content to invisible, back to visible etc. in a timed manner. For better results you could use CSS animations, with somewhat more limited browser support.
I have written a quick example to demonstrate how to create a layout programmatically.
public class CodeLayout extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Creating a new RelativeLayout
RelativeLayout relativeLayout = new RelativeLayout(this);
// Defining the RelativeLayout layout parameters.
// In this case I want to fill its parent
RelativeLayout.LayoutParams rlp = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.FILL_PARENT,
RelativeLayout.LayoutParams.FILL_PARENT);
// Creating a new TextView
TextView tv = new TextView(this);
tv.setText("Test");
// Defining the layout parameters of the TextView
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
lp.addRule(RelativeLayout.CENTER_IN_PARENT);
// Setting the parameters on the TextView
tv.setLayoutParams(lp);
// Adding the TextView to the RelativeLayout as a child
relativeLayout.addView(tv);
// Setting the RelativeLayout as our content view
setContentView(relativeLayout, rlp);
}
}
In theory everything should be clear as it is commented. If you don't understand something just tell me.
For space separated strings, then you can do this:
std::string s = "What is the right way to split a string into a vector of strings";
std::stringstream ss(s);
std::istream_iterator<std::string> begin(ss);
std::istream_iterator<std::string> end;
std::vector<std::string> vstrings(begin, end);
std::copy(vstrings.begin(), vstrings.end(), std::ostream_iterator<std::string>(std::cout, "\n"));
Output:

static cctype::mask rc[cctype::table_size];
std::memcpy(rc, const_rc, cctype::table_size * sizeof(cctype::mask));
rc[','] = std::ctype_base::space;
rc[' '] = std::ctype_base::space;
return &rc[0];
}
};
std::string s = "right way, wrong way, correct way";
std::stringstream ss(s);
ss.imbue(std::locale(std::locale(), new tokens()));
std::istream_iterator<std::string> begin(ss);
std::istream_iterator<std::string> end;
std::vector<std::string> vstrings(begin, end);
std::copy(vstrings.begin(), vstrings.end(), std::ostream_iterator<std::string>(std::cout, "\n"));
Output:

As a tangential note, one case where the ability to have multiple .gitignore
files is very useful is if you want an extra directory in your working copy that you never intend to commit. Just put a 1-byte .gitignore
(containing just a single asterisk) in that directory and it will never show up in git status
etc.
code that works, but output is:
10
20
30
40
50
so:
List<Integer> myCoords = new ArrayList<Integer>();
myCoords.add(10);
myCoords.add(20);
myCoords.add(30);
myCoords.add(40);
myCoords.add(50);
for (Integer number : myCoords) {
System.out.println(number);
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
It turns out it is because there was a mismatch between the postgre SQL version between my local and the server, installing the same version of PostgreSQL in my computer fixed the issue. Thanks!

The functionality of map
and filter
was intentionally changed to return iterators, and reduce was removed from being a built-in and placed in functools.reduce
.
So, for filter
and map
, you can wrap them with list()
to see the results like you did before.
>>> def f(x): return x % 2 != 0 and x % 3 != 0
...
>>> list(filter(f, range(2, 25)))
[5, 7, 11, 13, 17, 19, 23]
>>> def cube(x): return x*x*x
...
>>> list(map(cube, range(1, 11)))
[1, 8, 27, 64, 125, 216, 343, 512, 729, 1000]
>>> import functools
>>> def add(x,y): return x+y
...
>>> functools.reduce(add, range(1, 11))
55
>>>
The recommendation now is that you replace your usage of map and filter with generators expressions or list comprehensions. Example:
>>> def f(x): return x % 2 != 0 and x % 3 != 0
...
>>> [i for i in range(2, 25) if f(i)]
[5, 7, 11, 13, 17, 19, 23]
>>> def cube(x): return x*x*x
...
>>> [cube(i) for i in range(1, 11)]
[1, 8, 27, 64, 125, 216, 343, 512, 729, 1000]
>>>
They say that for loops are 99 percent of the time easier to read than reduce, but I'd just stick with functools.reduce
.
Edit: The 99 percent figure is pulled directly from the What’s New In Python 3.0 page authored by Guido van Rossum.
One possible idea is to write separate constructor function
//Something is the structure we work with
type Something struct {
Text string
DefaultText string
}
// NewSomething create new instance of Something
func NewSomething(text string) Something {
something := Something{}
something.Text = text
something.DefaultText = "default text"
return something
}
Use this as an example:
docker create --name new_ubuntu -it -p 8080:8080 -p 15672:15672 -p 5432:5432 ubuntu:latest bash
look what you've created(and copy its CONTAINER ID xxxxx):
docker ps -a
now write the miracle maker word(start):
docker start xxxxx

Use Promise.each of bluebird library.
Promise.each(
Iterable<any>|Promise<Iterable<any>> input,
function(any item, int index, int length) iterator
) -> Promise
This method iterates over an array, or a promise of an array, which contains promises (or a mix of promises and values) with the given iterator function with the signature (value, index, length) where the value is the resolved value of a respective promise in the input array. Iteration happens serially. If the iterator function returns a promise or a thenable, then the result of the promise is awaited before continuing with next iteration. If any promise in the input array is rejected, then the returned promise is rejected as well.
If all of the iterations resolve successfully, Promise.each resolves to the original array unmodified. However, if one iteration rejects or errors, Promise.each ceases execution immediately and does not process any further iterations. The error or rejected value is returned in this case instead of the original array.
This method is meant to be used for side effects.
var fileNames = ["1.txt", "2.txt", "3.txt"];
Promise.each(fileNames, function(fileName) {
return fs.readFileAsync(fileName).then(function(val){
// do stuff with 'val' here.
});
}).then(function() {
console.log("done");
});
No, cp
can copy multiple sources but will only copy to a single destination. You need to arrange to invoke cp
multiple times - once per destination - for what you want to do; using, as you say, a loop or some other tool.
You can get access to the environment variables in either the command line or in the registry.
Command Line
If you want a specific environment variable, then just type the name of it (e.g. PATH
), followed by a >
, and the filename to write to. The following will dump the PATH environment variable to a file named path.txt.
C:\> PATH > path.txt
Registry Method
The Windows Registry holds all the environment variables, in different places depending on which set you are after. You can use the registry Import/Export commands to shift them into the other PC.
For System Variables:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment
For User Variables:
HKEY_CURRENT_USER\Environment
If you have imported the project, you may have to re-import it the proper way.

FWIW, in Boostrap 4.4, you can add .text-wrap

You need to put the CTE first and then combine the INSERT INTO with your select statement. Also, the "AS" keyword following the CTE's name is not optional:
WITH tab AS (
bla bla
)
INSERT INTO dbo.prf_BatchItemAdditionalAPartyNos (
BatchID,
AccountNo,
APartyNo,
SourceRowID
)
SELECT * FROM tab
Please note that the code assumes that the CTE will return exactly four fields and that those fields are matching in order and type with those specified in the INSERT statement. If that is not the case, just replace the "SELECT *" with a specific select of the fields that you require.
As for your question on using a function, I would say "it depends". If you are putting the data in a table just because of performance reasons, and the speed is acceptable when using it through a function, then I'd consider function to be an option. On the other hand, if you need to use the result of the CTE in several different queries, and speed is already an issue, I'd go for a table (either regular, or temp).
You can set this programmatically in the controller:-
HttpContext.Current.Server.ScriptTimeout = 300;
Sets the timeout to 5 minutes instead of the default 110 seconds (what an odd default?)
It just means that the server cannot find your image.
Remember The image path must be relative to the CSS file location
Check the path and if the image file exist.

Amit-
I don't believe you can add a column anywhere but at the end of the table once the table is created. One solution might be to try this:
CREATE TABLE MY_TEMP_TABLE AS
SELECT *
FROM TABLE_TO_CHANGE;
Drop the table you want to add columns to:
DROP TABLE TABLE_TO_CHANGE;
It's at the point you could rebuild the existing table from scratch adding in the columns where you wish. Let's assume for this exercise you want to add the columns named "COL2 and COL3".
Now insert the data back into the new table:
INSERT INTO TABLE_TO_CHANGE (COL1, COL2, COL3, COL4)
SELECT COL1, 'Foo', 'Bar', COL4
FROM MY_TEMP_TABLE;
When the data is inserted into your "new-old" table, you can drop the temp table.
DROP TABLE MY_TEMP_TABLE;
This is often what I do when I want to add columns in a specific location. Obviously if this is a production on-line system, then it's probably not practical, but just one potential idea.

The simple way to retrieve checked value of RadioButtonList1 is:
$('#RadioButtonList1 input:checked').val()
Edit by Tim:
where RadioButtonList1
must be the ClientID of the RadioButtonList
var rblSelectedValue = $("#<%= RadioButtonList1.ClientID %> input:checked");
Try using this:
var x:Int!
var xTimesTwo:Int {
get {
return x * 2
}
set {
x = newValue / 2
}
}
This is basically Jack Wu's answer, but the difference is that in Jack Wu's answer his x variable is var x: Int
, in mine, my x variable is like this: var x: Int!
, so all I did was make it an optional type.
A typical situation where you cannot use [[
is in an autotools configure.ac script, there brackets has a special and different meaning, so you will have to use test
instead of [
or [[
-- Note that test and [
are the same program.
It is simple actually, like C programming you just need to pass the array indices on the right hand side while declaration. But yeah the syntax will be like [0:3] for 4 elements.
reg a[0:3];
This will create a 1D of array of single bit. Similarly 2D array can be created like this:
reg [0:3][0:2];
Now in C suppose you create a 2D array of int, then it will internally create a 2D array of 32 bits. But unfortunately Verilog is an HDL, so it thinks in bits rather then bunch of bits (though int datatype is there in Verilog), it can allow you to create any number of bits to be stored inside an element of array (which is not the case with C, you can't store 5-bits in every element of 2D array in C). So to create a 2D array, in which every individual element can hold 5 bit value, you should write this:
reg [0:4] a [0:3][0:2];
Thank you everyone. Your ways are perfect. I would like to share another way I used to fix the problem. I used the function os.chdir(path)
to change local directory to path. After which I saved image normally.
I believe it is because cell.getCellStyle
initially returns the default cell style which you then change.
Create styles like this and apply them to cells:
cellStyle = (XSSFCellStyle) cell.getSheet().getWorkbook().createCellStyle();
Although as the previous poster noted try and create styles and reuse them.
There is also some utility class in the XSSF library that will avoid the code I have provided and automatically try and reuse styles. Can't remember the class 0ff hand.
you can use this function to download file from base64.
function downloadPDF(pdf) {
const linkSource = `data:application/pdf;base64,${pdf}`;
const downloadLink = document.createElement("a");
const fileName = "abc.pdf";
downloadLink.href = linkSource;
downloadLink.download = fileName;
downloadLink.click();}
This code will made an anchor tag with href and download file. if you want to use button then you can call click method on your button click.
i hope this will help of you thanks
First, the error you're getting is due to where you're using the COUNT
function -- you can't use an aggregate (or group) function in the WHERE
clause.
Second, instead of using a subquery, simply join the table to itself:
SELECT a.pid
FROM Catalog as a LEFT JOIN Catalog as b USING( pid )
WHERE a.sid != b.sid
GROUP BY a.pid
Which I believe should return only rows where at least two rows exist with the same pid
but there is are at least 2 sid
s. To make sure you get back only one row per pid
I've applied a grouping clause.
Starting from Laravel 5.1.26, tagged on 2015-12-02, a useCurrent()
modifier has been added:
Schema::table('users', function ($table) {
$table->timestamp('created')->useCurrent();
});
PR 10962 (followed by commit 15c487fe) leaded to this addition.
You may also want to read issues 3602 and 11518 which are of interest.
Basically, MySQL 5.7 (with default config) requires you to define either a default value or nullable for time fields.
Just as another alternative you could use HASHBYTES, something like this:
SELECT *
FROM a_table
WHERE HASHBYTES('sha1', attribute) = HASHBYTES('sha1', 'k')
Yes you can do that.

OMG, I solved the same problem 5 minutes ago. I spent several hours to find a solution. At first sight disabling antivirus solved problem on Windows. But then I noticed issue on other linux pc with no antivirus. No errors in nginx logs. My uwsgi
showed something about "Broken pipe" but not on all requests.
Know what? It was no space left on device, which I found when restarted server on Database log, and df
approved this. Only explanation about why antivirus was solved this is that it prevents browser caching (it should check every request), but browser with some strange behavior can simply ignore bad response and show cached responses.
I did this many years back on 2003 or possibly 97, yikes!
If I recall you need to use one of the subcommands above tied to a timer. You cannot operate on the db with any connections or forms open.
So you do something about closing all forms, and kick off the timer as the last running method. (which will in turn call the compact operation once everything closes)
If you haven't figured this out I could dig through my archives and pull it up.
I encountered a similar error. It was a noob mistake done in a hurry. Integer array without declaring size int a[] then trying to access it. C++ compiler should've caught such an error easily if it were in main. However since this particular int array was declared inside an object, it was being created at the same time as my object (many objects were being created) and the compiler was throwing a free(): invalid next size(normal) error. I thought of 2 explanations for this (please enlighten me if anyone knows more): 1.) This resulted in some random memory being assigned to it but since this wasn't accessible it was freeing up all the other heap memory just trying to find this int. 2.) The memory required by it was practically infinite for a program and to assign this it was freeing up all other memory.
A simple:
int* a;
class foo{
foo(){
for(i=0;i<n;i++)
a=new int[i];
}
Solved the problem. But it did take a lot of time trying to debug this because the compiler could not "really" find the error.
I use:
int myint = 0;
long double myLD = 0.0;
string myint_str = static_cast<ostringstream*>(&(ostringstream() << myint))->str();
string myLD_str = static_cast<ostringstream*>(&(ostringstream() << myLD))->str();
It works on my Windows and Linux g++ compilers.
JosepStyons is right. Open cmd.exe and run
taskkill /im processname.exe /f
If there is an error saying,
ERROR: The process "process.exe" with PID 1234 could not be terminated. Reason: Access is denied.
then try running cmd.exe as administrator.
The IN clause describes a set of values, and sets do not have order.
Your solution with a join and then ordering on the display_order
column is the most nearly correct solution; anything else is probably a DBMS-specific hack (or is doing some stuff with the OLAP functions in standard SQL). Certainly, the join is the most nearly portable solution (though generating the data with the display_order
values may be problematic). Note that you may need to select the ordering columns; that used to be a requirement in standard SQL, though I believe it was relaxed as a rule a while ago (maybe as long ago as SQL-92).
I had problems with the same error on more than one Spring project. For me a general solution was, to split my service Method, that each INSERT, UPDATE and DELETE action got an own Method with @Transactional. I think this problem relates to the internal Spring managment, where database interactions are executed at the end of the method and, in my oppinion, this is the point, where the Exception is triggered.
Do you have a lot of applications running when you are trying this? I encounter weird behavior at work sometimes because my system runs out of GDI Handles as I have so many windows open (our apps use alot).
When this happens, windows and context menus no long appear until I close something to free up some GDI handles.
The default limit in XP and Vista is 10000. It is not uncommon for my DevStudio to have 1500 GDI handles, so if you have a couple of copies of Dev studio open, it can eat them up pretty quickly. You can add a column in TaskManager to see how many handles are being used by each process.
There is a registry tweak you can do to increase the limit.
For more information see http://msdn.microsoft.com/en-us/library/ms724291(VS.85).aspx
This is how I managed to make it work:
jQuery( document ).ready(function($) {
$('.myHTMLvideo').click(function() {
this.paused ? this.play() : this.pause();
});
});
All my HTML5 tags have the class 'myHTMLvideo'
This type of error occurs when the datatype of the SQL Server column has a length which is less than the length of the data entered into the entry form.
An important note is that using vendor SQL queries to retrieve the last inserted ID are safe to use without fearing about concurrent connections.
I always thought that you had to create a transaction in order to INSERT a line and then SELECT the last inserted ID in order to avoid retrieving an ID inserted by another client.
But these vendor specific queries always retrieve the last inserted ID for the current connection to the database. It means that the last inserted ID cannot be affected by other client insertions as long as they use their own database connection.
Composition to the rescue!
Given the reason, rather than invoking actions across controllers one should design controllers to seperate shared and custom parts of the code. This will help to avoid both - code duplication and breaking MVC pattern.
Although that can be done in a number of ways, using concerns (composition) is a good practice.
# controllers/a_controller.rb
class AController < ApplicationController
include Createable
private def redirect_url
'one/url'
end
end
# controllers/b_controller.rb
class BController < ApplicationController
include Createable
private def redirect_url
'another/url'
end
end
# controllers/concerns/createable.rb
module Createable
def create
do_usefull_things
redirect_to redirect_url
end
end
Hope that helps.
for the linq expression you can use like this :
List<int> list = new List<int>() {1,2,3 };
var result = (from l in list
select l).FirstOrDefault();
for the lambda expression you can use like this
List list = new List() { 1, 2, 3 }; int x = list.FirstOrDefault();
Easy solution would be:
curl http://jenkinsUrl/job/<Build_Name>/<Build_Number>/consoleText -OutFile <FilePathToLocalDisk>
or for the last successful build...
curl http://jenkinsUrl/job/<Build_Name>/lastSuccessfulBuild/consoleText -OutFile <FilePathToLocalDisk>
The serializer / deserializer solution pointed out by @xbakesx is an excellent one if you wish to completely decouple your enum class from its JSON representation.
Alternatively, if you prefer a self-contained solution, an implementation based on @JsonCreator
and @JsonValue
annotations would be more convenient.
So leveraging on the example by @Stanley the following is a complete self-contained solution (Java 6, Jackson 1.9):
public enum DeviceScheduleFormat {
Weekday,
EvenOdd,
Interval;
private static Map<String, DeviceScheduleFormat> namesMap = new HashMap<String, DeviceScheduleFormat>(3);
static {
namesMap.put("weekday", Weekday);
namesMap.put("even-odd", EvenOdd);
namesMap.put("interval", Interval);
}
@JsonCreator
public static DeviceScheduleFormat forValue(String value) {
return namesMap.get(StringUtils.lowerCase(value));
}
@JsonValue
public String toValue() {
for (Entry<String, DeviceScheduleFormat> entry : namesMap.entrySet()) {
if (entry.getValue() == this)
return entry.getKey();
}
return null; // or fail
}
}
To run multiple shell commands with ansible you can use the shell module with a multi-line string (note the pipe after shell:
), as shown in this example:
- name: Build nginx
shell: |
cd nginx-1.11.13
sudo ./configure
sudo make
sudo make install
The behaviour differs depending on whether the target file name already exists or not. It's usually a safety mechanism, and there are at least 3 different cases:
In this case svn mv
should work as follows:
$ svn mv old_file_name new_file_name
A new_file_name
D old_file_name
$ svn stat
A + new_file_name
> moved from old_file_name
D old_file_name
> moved to new_file_name
$ svn commit
Adding new_file_name
Deleting old_file_name
Committing transaction...
In this case, the target file needs to be removed explicitly, before the source file can be renamed. This can be done in the same transaction as follows:
$ svn mv old_file_name new_file_name
svn: E155010: Path 'new_file_name' is not a directory
$ svn rm new_file_name
D new_file_name
$ svn mv old_file_name new_file_name
A new_file_name
D old_file_name
$ svn stat
R + new_file_name
> moved from old_file_name
D old_file_name
> moved to new_file_name
$ svn commit
Replacing new_file_name
Deleting old_file_name
Committing transaction...
In the output of svn stat
, the R
indicates that the file has been replaced, and that the file has a history.
In this case, the content of the local file would be lost. If that's okay, then the file can be removed locally before renaming the existing file.
$ svn mv old_file_name new_file_name
svn: E155010: Path 'new_file_name' is not a directory
$ rm new_file_name
$ svn mv old_file_name new_file_name
A new_file_name
D old_file_name
$ svn stat
A + new_file_name
> moved from old_file_name
D old_file_name
> moved to new_file_name
$ svn commit
Adding new_file_name
Deleting old_file_name
Committing transaction...

Since my system (like so many other systems) had various network interfaces.InetAddress.getLocalHost()
or Inet4Address.getLocalHost()
simply returned one that I did not desire.
Therefore I had to use this naive approach.
InetAddress[] allAddresses = Inet4Address.getAllByName("YourComputerHostName");
InetAddress desiredAddress;
//In order to find the desired Ip to be routed by other modules (WiFi adapter)
for (InetAddress address :
allAddresses) {
if (address.getHostAddress().startsWith("192.168.2")) {
desiredAddress = address;
}
}
// Use the desired address for whatever purpose.
Just be careful that in this approach I already knew that my desired IP address is in 192.168.2
subnet.
Also defragment your disk. Netbeans is very aggressive about creating caches of one form or another. Most of them get persisted to disk at some point or another which can affect startup time. Virus scanners (Symantec in particular), Desktop search engines, and any other intrusive I/O product can drastically reduce performance.
I have noticed that Netbeans can be tempermental at times and its performance can vary greatly between two machines with nearly identical specs. My work machine has terrible performance and is unusable at times, but it's lightning fast when I use it on my home machine (with bigger projects in many cases).
Answer from 2019:
In my case I had to implement MainActivity
as Serializable
too. Cause I needed to start a service from my MainActivity
:
public class MainActivity extends AppCompatActivity implements Serializable {
...
musicCover = new MusicCover(); // A Serializable Object
...
sIntent = new Intent(MainActivity.this, MusicPlayerService.class);
sIntent.setAction(MusicPlayerService.ACTION_INITIALIZE_COVER);
sIntent.putExtra(MusicPlayerService.EXTRA_COVER, musicCover);
startService(sIntent);
}
Use encodeURIComponent()
in JS and in PHP you should receive the correct values.
Note: When you access $_GET
, $_POST
or $_REQUEST
in PHP, you are retrieving values that have already been decoded.
Example:
In your JS:
// url encode your string
var string = encodeURIComponent('+'); // "%2B"
// send it to your server
window.location = 'http://example.com/?string='+string; // http://example.com/?string=%2B
On your server:
echo $_GET['string']; // "+"
It is only the raw HTTP request that contains the url encoded data.
For a GET request you can retrieve this from the URI. $_SERVER['REQUEST_URI']
or $_SERVER['QUERY_STRING']
. For a urlencoded POST, file_get_contents('php://stdin')
NB:
decode()
only works for single byte encoded characters. It will not work for the full UTF-8 range.
eg:
text = "\u0100"; // A
// incorrect
escape(text); // %u0100
// correct
encodeURIComponent(text); // "%C4%80"
Note: "%C4%80"
is equivalent to: escape('\xc4\x80')
Which is the byte sequence (\xc4\x80
) that represents A
in UTF-8. So if you use encodeURIComponent()
your server side must know that it is receiving UTF-8. Otherwise PHP will mangle the encoding.
Do you mean something like:
SELECT COLUMN1, COLUMN2 FROM MY_TABLE WHERE COLUMN1 = 'Value' OR COLUMN1 IS NULL
?
Check into this thread,. However you should be careful as it's documented as "can change upon factory reset". Use at your own risk, and it can be easily changed on a rooted phone. Also it appears as if some manufacturers have had issues with their phones having duplicate numbers thread. Depending on what your trying to do, I probably wouldnt use this as a UID.
If it were a completely new row that you wanted to only set one value, you would need to add the whole row and then set the individual value:
DataRow dr = dt.NewRow();
dr[3].Value = "Some Value";
dt.Rows.Add(dr);
Otherwise, you can find the existing row and set the cell value
DataRow dr = dt.Rows[theRowNumber];
dr[3] = "New Value";
Try this... Worked for me and printed 10/22/2013 01:37:56 AM
Ofcourse this is your code only with little modifications.
final SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
sdf.setTimeZone(TimeZone.getTimeZone("UTC")); // This line converts the given date into UTC time zone
final java.util.Date dateObj = sdf.parse("2013-10-22T01:37:56");
aRevisedDate = new SimpleDateFormat("MM/dd/yyyy KK:mm:ss a").format(dateObj);
System.out.println(aRevisedDate);

Further to Stephen Weinberg's answer, I have since implemented a handy tool called iojson, which helps to populate data to an existing object easily as well as encoding the existing object to a JSON string. A iojson middleware is also provided to work with other middlewares. More examples can be found at https://github.com/junhsieh/iojson
Example:
func main() {
jsonStr := `{"Status":true,"ErrArr":[],"ObjArr":[{"Name":"My luxury car","ItemArr":[{"Name":"Bag"},{"Name":"Pen"}]}],"ObjMap":{}}`
car := NewCar()
i := iojson.NewIOJSON()
if err := i.Decode(strings.NewReader(jsonStr)); err != nil {
fmt.Printf("err: %s\n", err.Error())
}
// populating data to a live car object.
if v, err := i.GetObjFromArr(0, car); err != nil {
fmt.Printf("err: %s\n", err.Error())
} else {
fmt.Printf("car (original): %s\n", car.GetName())
fmt.Printf("car (returned): %s\n", v.(*Car).GetName())
for k, item := range car.ItemArr {
fmt.Printf("ItemArr[%d] of car (original): %s\n", k, item.GetName())
}
for k, item := range v.(*Car).ItemArr {
fmt.Printf("ItemArr[%d] of car (returned): %s\n", k, item.GetName())
}
}
}
Sample output:
car (original): My luxury car
car (returned): My luxury car
ItemArr[0] of car (original): Bag
ItemArr[1] of car (original): Pen
ItemArr[0] of car (returned): Bag
ItemArr[1] of car (returned): Pen
It's your "fault" in that that's how Or
is defined, so it's the behaviour you should expect:
In a Boolean comparison, the Or operator always evaluates both expressions, which could include making procedure calls. The OrElse Operator (Visual Basic) performs short-circuiting, which means that if expression1 is True, then expression2 is not evaluated.
But you don't have to endure it. You can use OrElse
to get short-circuiting behaviour.
So you probably want:
If (example Is Nothing OrElse Not example.Item = compare.Item) Then
'Proceed
End If
I can't say it reads terribly nicely, but it should work...
above answer didnt help me as my string value was "700.00"
with Swift 2.2 this works for me
let myString = "700.00"
let myInt = (myString as NSString).integerValue
I passed myInt to NSFormatterClass
let formatter = NSNumberFormatter()
formatter.numberStyle = .CurrencyStyle
formatter.maximumFractionDigits = 0
let priceValue = formatter.stringFromNumber(myInt!)!
//Now priceValue is ? 700
Thanks to this blog post.
In my case, it was the open_basedir which was defined. I commented it out (default) and my issue was resolved. I can now set the upload directory anywhere.
You can run H2 web server within your application that will access the same in-memory database. You can also access the H2 running in server mode using any generic JDBC client like SquirrelSQL.
UPDATE:
Server webServer = Server.createWebServer("-web,-webAllowOthers,true,-webPort,8082").start();
Server server = Server.createTcpServer("-tcp,-tcpAllowOthers,true,-tcpPort,9092").start();
Now you can connect to your database via jdbc:h2:mem:foo_db
URL within the same process or browse the foo_db
database using localhost:8082
. Remember to close both servers. See also: H2 database in memory mode cannot be accessed by Console.
You can also use Spring:
<bean id="h2Server" class="org.h2.tools.Server" factory-method="createTcpServer" init-method="start" destroy-method="stop" depends-on="h2WebServer">
<constructor-arg value="-tcp,-tcpAllowOthers,true,-tcpPort,9092"/>
</bean>
<bean id="h2WebServer" class="org.h2.tools.Server" factory-method="createWebServer" init-method="start" destroy-method="stop">
<constructor-arg value="-web,-webAllowOthers,true,-webPort,8082"/>
</bean>
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close" depends-on="h2Server">
<property name="driverClass" value="org.h2.Driver"/>
<property name="jdbcUrl" value="jdbc:h2:mem:foo_db"/>
</bean>
BTW you should only depend on assertions and not on manual peeking the database contents. Use this only for troubleshooting.
N.B. if you use Spring test framework you won't see changes made by a running transaction and this transaction will be rolled back immediately after the test.
Try this code:
final File f = new File(MyClass.class.getProtectionDomain().getCodeSource().getLocation().getPath());
replace 'MyClass
' with your class containing the main method.
Alternatively you can also use
System.getProperty("java.class.path")
Above mentioned System property provides
Path used to find directories and JAR archives containing class files. Elements of the class path are separated by a platform-specific character specified in the path.separator property.
Also worth noting you can use 'em' as well as 'px' - blogs and text based sites do it because then the browser makes layout decisions more relative to the text content.
On Wordpress twentysixteen I wanted my tagline to display on mobiles as well as desktops, so I put this in my child theme style.css
@media screen and (max-width:59em){
p.site-description {
display: block;
}
}
Because userString is empty. You only declare it
vector<string> userString;
but never add anything, so the for loop won't even run.

$( ".selector" ).datepicker( "option", "maxDate", '+0m +0w' );
I don't recommend encoding binary data in base64 and wrapping it in JSON. It will just needlessly increase the size of the response and slow things down.
Simply serve your file data using GET and application/octect-stream
using one of the factory methods of javax.ws.rs.core.Response
(part of the JAX-RS API, so you're not locked into Jersey):
@GET
@Produces(MediaType.APPLICATION_OCTET_STREAM)
public Response getFile() {
File file = ... // Initialize this to the File path you want to serve.
return Response.ok(file, MediaType.APPLICATION_OCTET_STREAM)
.header("Content-Disposition", "attachment; filename=\"" + file.getName() + "\"" ) //optional
.build();
}
If you don't have an actual File
object, but an InputStream
, Response.ok(entity, mediaType)
should be able to handle that as well.
You can use it this way

AssemblyVersion
Where other assemblies that reference your assembly will look. If this number changes, other assemblies have to update their references to your assembly! Only update this version, if it breaks backward compatibility. The AssemblyVersion
is required.
I use the format: major.minor. This would result in:
[assembly: AssemblyVersion("1.0")]
If you're following SemVer strictly then this means you only update when the major changes, so 1.0, 2.0, 3.0, etc.
AssemblyFileVersion
Used for deployment. You can increase this number for every deployment. It is used by setup programs. Use it to mark assemblies that have the same AssemblyVersion
, but are generated from different builds.
In Windows, it can be viewed in the file properties.
The AssemblyFileVersion is optional. If not given, the AssemblyVersion is used.
I use the format: major.minor.patch.build, where I follow SemVer for the first three parts and use the buildnumber of the buildserver for the last part (0 for local build). This would result in:
[assembly: AssemblyFileVersion("1.3.2.254")]
Be aware that System.Version names these parts as major.minor.build.revision
!
AssemblyInformationalVersion
The Product version of the assembly. This is the version you would use when talking to customers or for display on your website. This version can be a string, like '1.0 Release Candidate'.
The AssemblyInformationalVersion
is optional. If not given, the AssemblyFileVersion is used.
I use the format: major.minor[.patch] [revision as string]. This would result in:
[assembly: AssemblyInformationalVersion("1.0 RC1")]
What do you mean by "the count"? The number of elements with a non-zero value? You'd just have to count them.
There's no distinction between that array and one which has explicitly been set with zero values. For example, these arrays are indistinguishable:
int[] x = { 0, 0, 0 };
int[] y = new int[3];
Arrays in Java always have a fixed size - accessed via the length
field. There's no concept of "the amount of the array currently in use".
Here is simple example. A contact has one to many associated phone numbers. When a contact is deleted, I want all its associated phone numbers to also be deleted, so I use ON DELETE CASCADE. The one-to-many/many-to-one relationship is implemented with by the foreign key in the phone_numbers.
CREATE TABLE contacts
(contact_id BIGINT AUTO_INCREMENT NOT NULL,
name VARCHAR(75) NOT NULL,
PRIMARY KEY(contact_id)) ENGINE = InnoDB;
CREATE TABLE phone_numbers
(phone_id BIGINT AUTO_INCREMENT NOT NULL,
phone_number CHAR(10) NOT NULL,
contact_id BIGINT NOT NULL,
PRIMARY KEY(phone_id),
UNIQUE(phone_number)) ENGINE = InnoDB;
ALTER TABLE phone_numbers ADD FOREIGN KEY (contact_id) REFERENCES \
contacts(contact_id) ) ON DELETE CASCADE;
By adding "ON DELETE CASCADE" to the foreign key constraint, phone_numbers will automatically be deleted when their associated contact is deleted.
INSERT INTO table contacts(name) VALUES('Robert Smith');
INSERT INTO table phone_numbers(phone_number, contact_id) VALUES('8963333333', 1);
INSERT INTO table phone_numbers(phone_number, contact_id) VALUES('8964444444', 1);
Now when a row in the contacts table is deleted, all its associated phone_numbers rows will automatically be deleted.
DELETE TABLE contacts as c WHERE c.id=1; /* delete cascades to phone_numbers */
To achieve the same thing in Doctrine, to get the same DB-level "ON DELETE CASCADE" behavoir, you configure the @JoinColumn with the onDelete="CASCADE" option.
<?php
namespace Entities;
use Doctrine\Common\Collections\ArrayCollection;
/**

*/
protected $contact;
public function __construct($number=null)
{
if (!is_null($number)) {
$this->number = $number;
}
}
public function setPhonenumber($number)
{
$this->number = $number;
}
public function setContact(Contact $c)
{
$this->contact = $c;
}
}
?>
<?php
$em = \Doctrine\ORM\EntityManager::create($connectionOptions, $config);
$contact = new Contact("John Doe");
$phone1 = new Phonenumber("8173333333");
$phone2 = new Phonenumber("8174444444");
$em->persist($phone1);
$em->persist($phone2);
$contact->addPhonenumber($phone1);
$contact->addPhonenumber($phone2);
$em->persist($contact);

}
If you now do
# doctrine orm:schema-tool:create --dump-sql
you will see that the same SQL will be generated as in the first, raw-SQL example
this error basically comes when you use the object before using it.
Alternatively you can position your cursor on the item and show JavaDoc using
CTRL+Q
which is the default shortcut.
Edit: As Methical mentioned on Mac the shortcut is
CTRL+j (^+j not ?+j)
Hi Guys you cant convert directly string to bigdecimal
you need to first convert it into long after that u will convert big decimal
String currency = "135.69";
Long rate1=Long.valueOf((currency ));
System.out.println(BigDecimal.valueOf(rate1));
typeof(text) === 'string' || text instanceof String;
you can use this, it will work for both case as
var text="foo";
// typeof will work
String text= new String("foo");
// instanceof will work
// Factory returns object and ownership
// Caller responsible for deletion.
#include <memory>
class FactoryReleaseOwnership{
public:
std::unique_ptr<Foo> createFooInSomeWay(){
return std::unique_ptr<Foo>(new Foo(some, args));
}
};
// Factory retains object ownership
// Thus returning a reference.
#include <boost/ptr_container/ptr_vector.hpp>
class FactoryRetainOwnership{
boost::ptr_vector<Foo> myFoo;
public:
Foo& createFooInSomeWay(){
// Must take care that factory last longer than all references.
// Could make myFoo static so it last as long as the application.
myFoo.push_back(new Foo(some, args));
return myFoo.back();
}
};
My guess is that something is either encoding or decoding too often - or that you've got text with multiple lines in.
Base64 strings have to be a multiple of 4 characters in length - every 4 characters represents 3 bytes of input data. Somehow, the view state data being passed back by ASP.NET is corrupted - the length isn't a multiple of 4.
Do you log the user agent when this occurs? I wonder whether it's a badly-behaved browser somewhere... another possibility is that there's a proxy doing naughty things. Likewise try to log the content length of the request, so you can see whether it only happens for large requests.
The variable '$$' contains the PID.
a = ["item 1", "item 2", "item 3", "item 4"]
h = Hash[*a] # => { "item 1" => "item 2", "item 3" => "item 4" }
That's it. The *
is called the splat operator.
One caveat per @Mike Lewis (in the comments): "Be very careful with this. Ruby expands splats on the stack. If you do this with a large dataset, expect to blow out your stack."
So, for most general use cases this method is great, but use a different method if you want to do the conversion on lots of data. For example, @Lukasz Niemier (also in the comments) offers this method for large data sets:
h = Hash[a.each_slice(2).to_a]
You haven't created three different empty lists. You've created one empty list, and then created a new list with three references to that same empty list. To fix the problem use this code instead:
listy = [[] for i in range(3)]
Running your example code now gives the result you probably expected:
>>> listy = [[] for i in range(3)]
>>> listy[1] = [1,2]
>>> listy
[[], [1, 2], []]
>>> listy[1].append(3)
>>> listy
[[], [1, 2, 3], []]
>>> listy[2].append(1)
>>> listy
[[], [1, 2, 3], [1]]
The template it is referring to is the Html helper DisplayFor
.
DisplayFor expects to be given an expression that conforms to the rules as specified in the error message.
You are trying to pass in a method chain to be executed and it doesn't like it.
This is a perfect example of where the MVVM (Model-View-ViewModel) pattern comes in handy.
You could wrap up your Trainer
model class in another class called TrainerViewModel
that could work something like this:
class TrainerViewModel
{
private Trainer _trainer;
public string ShortDescription
{
get
{
return _trainer.Description.ToString().Substring(0, 100);
}
}
public TrainerViewModel(Trainer trainer)
{
_trainer = trainer;
}
}
You would modify your view model class to contain all the properties needed to display that data in the view, hence the name ViewModel.
Then you would modify your controller to return a TrainerViewModel
object rather than a Trainer
object and change your model type declaration in your view file to TrainerViewModel
too.
-f is the correct flag, but for the test operator, not rm
[ -f "$THEFILE" ] && rm "$THEFILE"
this ensures that the file exists and is a regular file (not a directory, device node etc...)
This is a fiddle I always use with my Web applications:
$('body').on('dragstart drop', function(e){
e.preventDefault();
return false;
});
It will prevent anything on your app being dragged and dropped. Depending on tour needs, you can replace body selector with any container that childrens should not be dragged.
I think the best way to do this with basic R is:
for( i in rownames(df) )
print(df[i, "column1"])
The advantage over the for( i in 1:nrow(df))
-approach is that you do not get into trouble if df
is empty and nrow(df)=0
.
you can try with this way
android:background="@color/white"

Verify current version of python by:
$ python --version
then check python is symbolic link to which file.
$ ll /usr/bin/python
Output Ex:
lrwxrwxrwx 1 root root 9 Jun 16 2014 /usr/bin/python -> python2.7*
Check other available versions of python:
$ ls /usr/bin/python*
Output Ex:
/usr/bin/python /usr/bin/python2.7-config /usr/bin/python3.4 /usr/bin/python3.4m-config /usr/bin/python3.6m /usr/bin/python3m
/usr/bin/python2 /usr/bin/python2-config /usr/bin/python3.4-config /usr/bin/python3.6 /usr/bin/python3.6m-config /usr/bin/python3m-config
/usr/bin/python2.7 /usr/bin/python3 /usr/bin/python3.4m /usr/bin/python3.6-config /usr/bin/python3-config /usr/bin/python-config
If want to change current version of python to 3.6 version edit file ~/.bashrc:
vim ~/.bashrc
add below line in the end of file and save:
alias python=/usr/local/bin/python3.6
To install pip for python 3.6
$ sudo apt-get install python3.6 python3.6-dev
$ sudo curl https://bootstrap.pypa.io/ez_setup.py -o - | sudo python3.6
$ sudo easy_install pip
On Success, check current version of pip:
$ pip3 -V
Output Ex:
pip 1.5.4 from /usr/lib/python3/dist-packages (python 3.6)
In PostgreSQL we use this approach:
SELECT round(EXTRACT (EPOCH FROM now())::float*1000)
My understanding is that "-u" or "--set-upstream" allows you to specify the upstream (remote) repository for the branch you're on, so that next time you run "git push", you don't even have to specify the remote repository.
Push and set upstream (remote) repository as origin:
$ git push -u origin
Next time you push, you don't have to specify the remote repository:
$ git push
As other guys commented before you can write your own procedure with anonymous function to solve this issue.
I used two ways to solve it:
func Find(slice interface{}, f func(value interface{}) bool) int {
s := reflect.ValueOf(slice)
if s.Kind() == reflect.Slice {
for index := 0; index < s.Len(); index++ {
if f(s.Index(index).Interface()) {
return index
}
}
}
return -1
}
Uses example:
type UserInfo struct {
UserId int
}
func main() {
var (
destinationList []UserInfo
userId int = 123
)
destinationList = append(destinationList, UserInfo {
UserId : 23,
})
destinationList = append(destinationList, UserInfo {
UserId : 12,
})
idx := Find(destinationList, func(value interface{}) bool {
return value.(UserInfo).UserId == userId
})
if idx < 0 {
fmt.Println("not found")
} else {
fmt.Println(idx)
}
}
Second method with less computational cost:
func Search(length int, f func(index int) bool) int {
for index := 0; index < length; index++ {
if f(index) {
return index
}
}
return -1
}
Uses example:
type UserInfo struct {
UserId int
}
func main() {
var (
destinationList []UserInfo
userId int = 123
)
destinationList = append(destinationList, UserInfo {
UserId : 23,
})
destinationList = append(destinationList, UserInfo {
UserId : 123,
})
idx := Search(len(destinationList), func(index int) bool {
return destinationList[index].UserId == userId
})
if idx < 0 {
fmt.Println("not found")
} else {
fmt.Println(idx)

Using Java.util.ArrayList or LinkedList is the usual way of doing this. With arrays that's not possible as I know.
Example:
List<Float> unindexedVectors = new ArrayList<Float>();
unindexedVectors.add(2.22f);
unindexedVectors.get(2);
As others have pointed out, sqlite's ALTER TABLE
statement does not support DROP COLUMN
, and the standard recipe to do this does not preserve constraints & indices.
Here's some python code to do this generically, while maintaining all the key constraints and indices.
Please back-up your database before using! This function relies on doctoring the original CREATE TABLE statement and is potentially a bit unsafe - for instance it will do the wrong thing if an identifier contains an embedded comma or parenthesis.
If anyone would care to contribute a better way to parse the SQL, that would be great!
UPDATE I found a better way to parse using the open-source sqlparse
package. If there is any interest I will post it here, just leave a comment asking for it ...

def DROP_COLUMN(db, table, column):
columns = [ c[1] for c in db.execute("PRAGMA table_info(%s)" % table) ]

sql = db.execute("SELECT sql from sqlite_master where name = '%s'"
% table).fetchone()[0]
sql = format(sql)
lines = sql.splitlines()
findcol = r'\b%s\b' % column

With Apache Commons Library, you can simply use Stringutils.replaceEach:
public static String replaceEach(String text,
String[] searchList,
String[] replacementList)
From the documentation:
Replaces all occurrences of Strings within another String.
A null reference passed to this method is a no-op, or if any "search string" or "string to replace" is null, that replace will be ignored. This will not repeat. For repeating replaces, call the overloaded method.
StringUtils.replaceEach(null, *, *) = null
StringUtils.replaceEach("", *, *) = ""
StringUtils.replaceEach("aba", null, null) = "aba"
StringUtils.replaceEach("aba", new String[0], null) = "aba"
StringUtils.replaceEach("aba", null, new String[0]) = "aba"
StringUtils.replaceEach("aba", new String[]{"a"}, null) = "aba"
StringUtils.replaceEach("aba", new String[]{"a"}, new String[]{""}) = "b"
StringUtils.replaceEach("aba", new String[]{null}, new String[]{"a"}) = "aba"
StringUtils.replaceEach("abcde", new String[]{"ab", "d"}, new String[]{"w", "t"}) = "wcte"
(example of how it does not repeat)
StringUtils.replaceEach("abcde", new String[]{"ab", "d"}, new String[]{"d", "t"}) = "dcte"
Others have explained what NoneType
is and a common way of ending up with it (i.e., failure to return a value from a function).
Another common reason you have None
where you don't expect it is assignment of an in-place operation on a mutable object. For example:
mylist = mylist.sort()
The sort()
method of a list sorts the list in-place, that is, mylist
is modified. But the actual return value of the method is None
and not the list sorted. So you've just assigned None
to mylist
. If you next try to do, say, mylist.append(1)
Python will give you this error.
This worked for me and does not require background color behind the text to hide a border line, instead uses actual hr tag. You can play around with the widths to get different sizes of hr lines.
<div>
<div style="display:inline-block;width:45%"><hr width='80%' /></div>
<div style="display:inline-block;width: 9%;text-align: center;vertical-align:90%;text-height: 24px"><h4>OR</h4></div>
<div style="display:inline-block;width:45%;float:right" ><hr width='80%'/></div>
</div>
If you're installing using --user
(e.g. pip3.6 install --user tmuxp
), it is possible to get the platform-specific user install directory from Python itself using the site
module. For example, on macOS:
$ python2.7 -m site --user-base
/Users/alexp/Library/Python/2.7
By appending /bin
to this, we now have the path where package executables will be installed. We can dynamically populate the PATH in your shell's rc file based on the output; I'm using bash, but with any luck this is portable:
# Add Python bin directories to path
python3.6 -m site &> /dev/null && PATH="$PATH:`python3.6 -m site --user-base`/bin"
python2.7 -m site &> /dev/null && PATH="$PATH:`python2.7 -m site --user-base`/bin"
I use the precise Python versions to reduce the chance of the executables just "disappearing" when Python upgrades a minor version, e.g. from 3.5 to 3.6. They'll disappear because, as can be seen above, the user installation path may include the Python version. So while python3
could point to 3.5 or 3.6, python3.6
will always point to 3.6. This needs to be kept in mind when installing further packages, e.g. use pip3.6
over pip3
.
If you don't mind the idea of packages disappearing, you can use python2
and python3
instead:
# Add Python bin directories to path
# Note: When Python is upgraded, packages may need to be re-installed
# or Python versions managed.
python3 -m site &> /dev/null && PATH="$PATH:`python3 -m site --user-base`/bin"
python2 -m site &> /dev/null && PATH="$PATH:`python2 -m site --user-base`/bin"
You can use Array#map
with Array#find
.
arr1.map(obj => arr2.find(o => o.id === obj.id) || obj);
var arr1 = [{_x000D_
id: '124',_x000D_
name: 'qqq'_x000D_
}, {_x000D_
id: '589',_x000D_
name: 'www'_x000D_
}, {_x000D_
id: '45',_x000D_
name: 'eee'_x000D_
}, {_x000D_
id: '567',_x000D_
name: 'rrr'_x000D_
}];_x000D_
_x000D_
var arr2 = [{_x000D_
id: '124',_x000D_
name: 'ttt'_x000D_
}, {_x000D_
id: '45',_x000D_
name: 'yyy'_x000D_
}];_x000D_
_x000D_
var res = arr1.map(obj => arr2.find(o => o.id === obj.id) || obj);_x000D_
_x000D_
console.log(res);
_x000D_
Here, arr2.find(o => o.id === obj.id)
will return the element i.e. object from arr2
if the id
is found in the arr2
. If not, then the same element in arr1
i.e. obj
is returned.
As it allows to install more than one version of java, I had install many 3 versions unknowingly but it was point to latest version "11.0.2"
I could able to solve this issue with below steps to move to "1.8"

For pre 1.7 i would say an equivalent to Integer.compare(x, y) is:
Integer.valueOf(x).compareTo(y);
I am coming from an Electron environment, where I need IPC communication between a renderer process and the main process. The renderer process sits in an HTML file between script tags and generates the same error.
The line
const {ipcRenderer} = require('electron')
throws the Uncaught ReferenceError: require is not defined
I was able to work around that by specifying Node.js integration as true when the browser window (where this HTML file is embedded) was originally created in the main process.
function createAddItemWindow() {
// Create a new window
addItemWindown = new BrowserWindow({
width: 300,
height: 200,
title: 'Add Item',
// The lines below solved the issue
webPreferences: {
nodeIntegration: true
}
})}
That solved the issue for me. The solution was proposed here.
Use sortedWith
to sort a list with Comparator
.
You can then construct a comparator using several ways:
Just cast your double to a float.
double d = getInfoValueNumeric();
float f = (float)d;
Also notice that the primitive types can NOT store an infinite set of numbers:
float range: from 1.40129846432481707e-45 to 3.40282346638528860e+38
double range: from 1.7e–308 to 1.7e+308
I solved the problem by using the Rnd() function:
Function RollD6() As UInteger
RollD6 = (Math.Floor(6 * Rnd())) + 1
Return RollD6
End Function
When the form loads, I use the Randomize() method to make sure I don't always get the same sequence of random numbers from run to run.
It is better to use error codes, you don't have to parse.
try
{
}
catch (SqlException exception)
{
if (exception.Number == 208)
{
}
else
throw;
}
How to find out that 208 should be used:
select message_id
from sys.messages
where text like 'Invalid object name%'
You can also use numpy loadtxt like
from numpy import loadtxt
lines = loadtxt("filename.dat", comments="#", delimiter=",", unpack=False)
You could use pandas plot as @Bharath suggest:
import seaborn as sns
sns.set()
df.set_index('App').T.plot(kind='bar', stacked=True)
Output:
Updated:
from matplotlib.colors import ListedColormap
df.set_index('App')\
.reindex_axis(df.set_index('App').sum().sort_values().index, axis=1)\
.T.plot(kind='bar', stacked=True,
colormap=ListedColormap(sns.color_palette("GnBu", 10)),
figsize=(12,6))
Updated Pandas 0.21.0+ reindex_axis
is deprecated, use reindex
from matplotlib.colors import ListedColormap
df.set_index('App')\
.reindex(df.set_index('App').sum().sort_values().index, axis=1)\
.T.plot(kind='bar', stacked=True,
colormap=ListedColormap(sns.color_palette("GnBu", 10)),
figsize=(12,6))
Output:
sudo npm install -g @angular/cli
use this. it worked for me
Here is a method, that takes datetime(format:01-01-2012 12:00:00)
and returns string(format: 01-01-2012)
public static string GetDateFromDateTime(DateTime datevalue){
return datevalue.ToShortDateString();
}
How about some examples to show it in action...
@Test
public void isInstanceOf() {
Exception anEx1 = new Exception("ex");
Exception anEx2 = new RuntimeException("ex");
RuntimeException anEx3 = new RuntimeException("ex");
//Base case, handles inheritance

Assert.assertTrue(anEx2 instanceof Exception);
Assert.assertTrue(anEx3 instanceof Exception);
//Other cases

Assert.assertTrue(anEx2 instanceof RuntimeException);
Assert.assertTrue(anEx3 instanceof RuntimeException);
}
@Test

Exception anEx2 = new RuntimeException("ex");
RuntimeException anEx3 = new RuntimeException("ex");
//Correct usage = The base class goes first
Assert.assertTrue(Exception.class.isAssignableFrom(anEx1.getClass()));
Assert.assertTrue(Exception.class.isAssignableFrom(anEx2.getClass()));
Assert.assertTrue(Exception.class.isAssignableFrom(anEx3.getClass()));
//Incorrect usage = Method parameter is used in the wrong order
Assert.assertTrue(anEx1.getClass().isAssignableFrom(Exception.class));
Assert.assertFalse(anEx2.getClass().isAssignableFrom(Exception.class));
Assert.assertFalse(anEx3.getClass().isAssignableFrom(Exception.class));

Go to the folder where Python is installed .. and go to Scripts folder .
Do all this in CMD and then type :
pip
to check whether its there or not .
As soon as it shows some list it means that it is there .
Then type
pip install <package name you want to install>
To include Unicode characters in your Python source code, you can use Unicode escape characters in the form \u0123
in your string. In Python 2.x, you also need to prefix the string literal with 'u'.
Here's an example running in the Python 2.x interactive console:
>>> print u'\u0420\u043e\u0441\u0441\u0438\u044f'
??????
In Python 2, prefixing a string with 'u' declares them as Unicode-type variables, as described in the Python Unicode documentation.
In Python 3, the 'u' prefix is now optional:
>>> print('\u0420\u043e\u0441\u0441\u0438\u044f')
??????
If running the above commands doesn't display the text correctly for you, perhaps your terminal isn't capable of displaying Unicode characters.
These examples use Unicode escapes (\u...
), which allows you to print Unicode characters while keeping your source code as plain ASCII. This can help when working with the same source code on different systems. You can also use Unicode characters directly in your Python source code (e.g. print u'??????'
in Python 2), if you are confident all your systems handle Unicode files properly.
For information about reading Unicode data from a file, see this answer:

Here is a pure python method for simple strings, left here for posterity.
def string2bits(s=''):
return [bin(ord(x))[2:].zfill(8) for x in s]
def bits2string(b=None):
return ''.join([chr(int(x, 2)) for x in b])
s = 'Hello, World!'
b = string2bits(s)
s2 = bits2string(b)
print 'String:'
print s
print '\nList of Bits:'
for x in b:
print x
print '\nString:'
print s2
String:
Hello, World!
List of Bits:
01001000
01100101
01101100
01101100
01101111

String:

Python 2.x and Python 3.x are different. If you would like to download a newer version of Python 2, you could just download and install the newer version.
If you want to install Python 3, you could install Python 3 separately then change the path for Python 2.x to Python 3.x in Control Panel > All Control Panel Items > System > Advanced System Settings > Environment Variables.

Pure JSP comments look like this:
<%-- Comment --%>
So if you want to retain the "=
".you could do something like:
<%--= map.size() --%>
The key thing is that <%=
defines the beginning of an expression, in which you can't leave the body empty, but you could do something like this instead if the pure JSP comment doesn't appeal to you:
<% /*= map.size()*/ %>
Code Conventions for the JavaServer Pages Technology Version 1.x Language has details about the different commenting options available to you (but has a complete lack of link targets, so I can't link you directly to the relevant section - boo!)

Faster previous

New syntax (either):
test = df.sort_values(['one'], ascending=[False])
test = df.sort_values(['one'], ascending=[0])
To me it seems @atomicules has the simplest answer, but I think it can be simplified a little more. You need to put an @
before anything you want to be global, so that it compiles to this.anything
and this
refers to the global object.

Another product that can handle this elegantly is SmartAssembly, at SmartAssembly.com. This product will, in addition to merging all dependencies into a single DLL, (optionally) obfuscate your code, remove extra meta-data to reduce the resulting file size, and can also actually optimize the IL to increase runtime performance.
There is also some kind of global exception handling/reporting feature it adds to your software (if desired) that could be useful. I believe it also has a command-line API so you can make it part of your build process.
IANAL but as I see it....
While you can combine GPL and MIT code, the GPL is tainting. Which means the package as a whole gets the limitations of the GPL. As that is more restrictive you can no longer use it in commercial (or rather closed source) software. Which also means if you have a MIT/BSD/ASL project you will not want to add dependencies to GPL code.
Adding a GPL dependency does not change the license of your code but it will limit what people can do with the artifact of your project. This is also why the ASF does not allow dependencies to GPL code for their projects.

I know it's now 2020, but I couldn't see an answer that satisfied the "ignore" part of the question. Turns out, you can tell TSLint to do just that using a directive;
// @ts-ignore
this.x = this.x.filter(x => x.someProp !== false);
Normally this would throw an error, stating that 'someProp does not exist on type'. With the comment, that error goes away.
This will stop any errors being thrown when compiling and should also stop your IDE complaining at you.
How can I convert tabs to spaces in every file of a directory (possibly recursively)?
This is usually not what you want.
Do you want to do this for png images? PDF files? The .git directory? Your
Makefile
(which requires tabs)? A 5GB SQL dump?
You could, in theory, pass a whole lot of exlude options to find
or whatever
else you're using; but this is fragile, and will break as soon as you add other
binary files.
What you want, is at least:
expand
does this, sed
doesn't).As far as I know, there is no "standard" Unix utility that can do this, and it's not very easy to do with a shell one-liner, so a script is needed.
A while ago I created a little script called
sanitize_files which does exactly
that. It also fixes some other common stuff like replacing \r\n
with \n
,
adding a trailing \n
, etc.
You can find a simplified script without the extra features and command-line arguments below, but I recommend you use the above script as it's more likely to receive bugfixes and other updated than this post.
I would also like to point out, in response to some of the other answers here,
that using shell globbing is not a robust way of doing this, because sooner
or later you'll end up with more files than will fit in ARG_MAX
(on modern
Linux systems it's 128k, which may seem a lot, but sooner or later it's not
enough).

This need is exactly why createInsecureRfcommSocketToServiceRecord()
was added to BluetoothDevice
starting in Android 2.3.3 (API Level 10) (SDK Docs)...before that there was no SDK support for this. It was designed to allow Android to connect to devices without user interfaces for entering a PIN code (like an embedded device), but it just as usable for setting up a connection between two devices without user PIN entry.
The corollary method listenUsingInsecureRfcommWithServiceRecord()
in BluetoothAdapter
is used to accept these types of connections. It's not a security breach because the methods must be used as a pair. You cannot use this to simply attempt to pair with any old Bluetooth device.
You can also do short range communications over NFC, but that hardware is less prominent on Android devices. Definitely pick one, and don't try to create a solution that uses both.
Hope that Helps!
P.S. There are also ways to do this on many devices prior to 2.3 using reflection, because the code did exist...but I wouldn't necessarily recommend this for mass-distributed production applications. See this StackOverflow.
A way for integers without banal converting to string
:
var num = 9999999999; // your number
var length = 1;
while (num >= 10) {
num /= 10;
length++;
}
alert(length);
well looking for a simpler variation I found this:
it's truly smart, and I guess you might want to add other browsers variations too although it worked for me both on Chrome and Firefox.

Just a small correction to the first answer in this thread.
Even for Stack, you need to create new object with generics if you are using Stack from java util packages.
Right usage:
Stack<Integer> s = new Stack<Integer>();
Stack<String> s1 = new Stack<String>();
s.push(7);
s.push(50);
s1.push("string");
s1.push("stack");
if used otherwise, as mentioned in above post, which is:
/*
Stack myStack = new Stack();
// add any type of elements (String, int, etc..)
myStack.push("Hello");
myStack.push(1);
*/
Although this code works fine, has unsafe or unchecked operations which results in error.
#include <iostream>
#include <string>
using namespace std;
int main()
{
cout << stod(" 99.999 ") << endl;
}
Output: 99.999
(which is double, whitespace was automatically stripped)
Since C++11 converting string to floating-point values (like double) is available with functions:
stof - convert str to a float
stod - convert str to a double
stold - convert str to a long double
As conversion of string to int was also mentioned in the question, there are the following functions in C++11:
stoi - convert str to an int
stol - convert str to a long
stoul - convert str to an unsigned long
stoll - convert str to a long long
stoull - convert str to an unsigned long long
I have come up with the following solution to this problem:
def iter_var1(d):
for _, row in d.iterrows():
for v in row["var1"].split(","):
yield (v, row["var2"])
new_a = DataFrame.from_records([i for i in iter_var1(a)],
columns=["var1", "var2"])
I had to merge some of those good answers here! This works for me:
git remote set-url origin 'https://bitbucket.org/teamName/repo.git'
In the end, it will always prompt anyone who wants to pull from it

This solution helped me to progress on my project.
$("#your_textbox").on("input propertychange",function(){
// Do your thing here.
});
Note: propertychange for lower versions of IE.
Here I updated the sample code in Kotlin. Please note on Nougat and above version Uri.fromFile(file)
is not working and it crashes the app for that need to implement FileProvider which is safest way to send files from intent. For implementing this refer this answer or this article
private fun takePhotoFromCamera() {
val isDeviceSupportCamera: Boolean = this.packageManager.hasSystemFeature(PackageManager.FEATURE_CAMERA)
if (isDeviceSupportCamera) {
val takePictureIntent = Intent(MediaStore.ACTION_IMAGE_CAPTURE)
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
file = File(getExternalFilesDir(Environment.DIRECTORY_DOCUMENTS + "/attachments")!!.path,
System.currentTimeMillis().toString() + ".jpg")
// fileUri = Uri.fromFile(file)
fileUri = FileProvider.getUriForFile(this, this.applicationContext.packageName + ".provider", file!!)
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri)
if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.LOLLIPOP) {
takePictureIntent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION)
}
startActivityForResult(takePictureIntent, Constants.REQUEST_CODE_IMAGE_CAPTURE)
}
} else {
Toast.makeText(this, this.getString(R.string.camera_not_supported), Toast.LENGTH_SHORT).show()
}
}
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (resultCode == Activity.RESULT_OK) {
if(requestCode == Constants.REQUEST_CODE_IMAGE_CAPTURE) {
realPath = file?.path
//do what ever you want to do
}
}
}
You are assigning reloaded items to global variable items in onResume()
, but this will not reflect in ItemAdapter
class, because it has its own instance variable called 'items'.
For refreshing ListView
, add a refresh() in ItemAdapter
class which accepts list data i.e items
class ItemAdapter
{
.....
public void refresh(List<Item> items)
{
this.items = items;
notifyDataSetChanged();
}
}
update onResume()
with following code
@Override
public void onResume()
{
super.onResume();
items.clear();
items = dbHelper.getItems(); //reload the items from database
**adapter.refresh(items);**
}
You need to declare disconnectFunc as a function pointer, not a void pointer. You also need to call it as a function (with parentheses), and no "*" is needed.
From my research and starting on this post, i think this is the best option:
<p style=" position: absolute; bottom: 0; left: 0; width: 100%; text-align: center;">This will stick at the botton no matter what :).</p>
_x000D_
This option allow resizes of the page and even if the page is blank it will stick at the bottom.
instead of redirection I would do the following
mysql -h <hostname> -u <username> --password=<password> -D <database> -e 'source <path-to-sql-file>'
This will execute the file path-to-sql-file
