Assuming that "a" and "b" are bean properties
rendered="#{bean.a==12 and (bean.b==13 or bean.b==15)}"

This should do it for you:
Declare @DatePeriod datetime
Set @DatePeriod = '2011-05-30'
Select ProductName,
IsNull([1],0) as 'Week 1',
IsNull([2],0) as 'Week 2',
IsNull([3],0) as 'Week 3',
IsNull([4],0) as 'Week 4',
IsNull([5], 0) as 'Week 5'
From
(
Select ProductName,
DATEDIFF(week, DATEADD(MONTH, DATEDIFF(MONTH, 0, InputDate), 0), InputDate) +1 as [Weeks],
Sale as 'Sale'
From dbo.YourTable
-- Only get rows where the date is the same as the DatePeriod
-- i.e DatePeriod is 30th May 2011 then only the weeks of May will be calculated
Where DatePart(Month, InputDate)= DatePart(Month, @DatePeriod)
)p
Pivot (Sum(Sale) for Weeks in ([1],[2],[3],[4],[5])) as pv
It will calculate the week number relative to the month. So instead of week 20 for the year it will be week 2. The @DatePeriod
variable is used to fetch only rows relative to the month (in this example only for the month of May)

EDIT: see bobince's solution which uses contains rather than start-with, along with a trick to ensure the comparison is done at the level of a complete token (lest the 'atag' pattern be found as part of another 'tag').
"atag btag" is an odd value for the class attribute, but never the less, try:
//*[starts-with(@class,"atag")]
Performing a lock: Quite cheap (still more expensive than a null test).
Performing a lock when another thread has it: You get the cost of whatever they've still to do while locking, added to your own time.
Performing a lock when another thread has it, and dozens of other threads are also waiting on it: Crippling.
For performance reasons, you always want to have locks that another thread wants, for the shortest period of time at all possible.
Of course it's easier to reason about "broad" locks than narrow, so it's worth starting with them broad and optimising as needed, but there are some cases that we learn from experience and familiarity where a narrower fits the pattern.
(Incidentally, if you can possibly just use private static volatile Singleton instance = new Singleton()
or if you can possibly just not use singletons but use a static class instead, both are better in regards to these concerns).
I used this whit jQuery: http://jsfiddle.net/daviderussoabram/65w1qhLz/
$('input[type="date"], input[type="datetime"], input[type="datetime-local"], input[type="month"], input[type="time"], input[type="week"]').each(function() {
var el = this, type = $(el).attr('type');
if ($(el).val() == '') $(el).attr('type', 'text');
$(el).focus(function() {
$(el).attr('type', type);
el.click();
});
$(el).blur(function() {
if ($(el).val() == '') $(el).attr('type', 'text');
});
});
It's platform-specific. But you can cast it to a known type.
printf("%lld\n", (long long) time(NULL));
To simplify the answare let's look on the following code:
#include "stdafx.h"
#include <iostream>
using namespace std;
class A
{
private:
int m_id;
static int count;
public:
A() {count++; m_id = count;}
A(int id) { m_id = id; }
~A() {cout<< "Destructor A " <<m_id<<endl; }
};
int A::count = 0;
void f1()
{
A* arr = new A[10];
//delete operate only one constructor, and crash!
delete arr;
//delete[] arr;
}
int main()
{
f1();
system("PAUSE");
return 0;
}
The output is: Destructor A 1 and then it's crashing (Expression: _BLOCK_TYPE_IS_VALID(phead- nBlockUse)).
We need to use: delete[] arr; becuse it's delete the whole array and not just one cell!
try to use delete[] arr; the output is: Destructor A 10 Destructor A 9 Destructor A 8 Destructor A 7 Destructor A 6 Destructor A 5 Destructor A 4 Destructor A 3 Destructor A 2 Destructor A 1
The same principle is for an array of pointers:
void f2()
{
A** arr = new A*[10];
for(int i = 0; i < 10; i++)
{
arr[i] = new A(i);
}
for(int i = 0; i < 10; i++)
{
delete arr[i];//delete the A object allocations.
}
delete[] arr;//delete the array of pointers
}
if we'll use delete arr instead of delete[] arr. it will not delete the whole pointers in the array => memory leak of pointer objects!
I encountered this problem when working with COM objects. Under certain circumstances (my fault), I destroyed an external .EXE process, in a parallel thread, a variable tried to access the com interface app.method and a COM-level crash occurred. Task Scheduler noticed this and shut down the app. But if you run the app in the console and don't handle the exception, the app will continue to work ...
Please note that if you use unmanaged code or external objects (AD, Socket, COM ...), you need to monitor them!
For method decorator declaration
with configuration "noImplicitAny": true,
you can specify type of this variable explicitly depends on @tony19's answer
function logParameter(this:any, target: Object, propertyName: string) {

If you are using Xamarin Forms and you move a XAML file the "build action" of the file is changed. Xamarin Forms requires "build action = Embedded Resource".
Apply "build action" in Visual Studio:
Select the XAML file -> Properties -> Build Action = Embedded Resource
As others have mentioned, use triple quotes ”””abc”””
for multiline strings. Also, you can do this without having to call close()
using the with
keyword. For example:
# HTML String
html = """
<table border=1>
<tr>
<th>Number</th>
<th>Square</th>
</tr>
<indent>
<% for i in range(10): %>
<tr>
<td><%= i %></td>
<td><%= i**2 %></td>
</tr>
</indent>
</table>
"""
# Write HTML String to file.html
with open("file.html", "w") as file:
file.write(html)
See https://stackoverflow.com/a/11783672/2206251 for more details on the with
keyword in Python.
if you want to use Collections.fill(list, obj); in order to fill the list with a repeated object alternatively you can use
ArrayList<Integer> arr=new ArrayList<Integer>(Collections.nCopies(10, 0));
the line copies 10 times 0 in to your ArrayList
No offense but to check for performance of sql I executed some of the above mentioned solutiona pgsql.
Let me share you Statistics of top 3 solution approaches that I come across.
1) Took : 1.58 MS Avg
2) Took : 2.87 MS Avg
3) Took : 3.95 MS Avg
Now try this :
SELECT * FROM table WHERE DATE_TRUNC('day', date ) >= Start Date AND DATE_TRUNC('day', date ) <= End Date
Now this solution took : 1.61 Avg.
And best solution is 1st that suggested by marco-mariani
Is there a js listener for when a user scrolls in a certain textbox that can be used?
DOM L3 UI Events spec gave the initial definition but is considered obsolete.
To add a single handler you can do:
let isTicking;
const debounce = (callback, evt) => {
if (isTicking) return;
requestAnimationFrame(() => {
callback(evt);
isTicking = false;
});
isTicking = true;
};
const handleScroll = evt => console.log(evt, window.scrollX, window.scrollY);
document.defaultView.onscroll = evt => debounce(handleScroll, evt);
For multiple handlers or, if preferable for style reasons, you may use addEventListener
as opposed to assigning your handler to onscroll
as shown above.
If using something like _.debounce
from lodash you could probably get away with:
const handleScroll = evt => console.log(evt, window.scrollX, window.scrollY);
document.defaultView.onscroll = evt => _.debounce(() => handleScroll(evt));
Review browser compatibility and be sure to test on some actual devices before calling it done.
I'm using OS X (Yosemite) and this error happened to me when I upgraded from Mavericks to Yosemite. It was solved by using this command

After spending a lot of time trying to resolve this issue, finally found a solution that works. The solution makes use of Spring's ResourceUtils. Should work for json files as well.

To answer a few concerns on the comments :
Pretty sure I had this running on Amazon EC2 using java -jar target/image-service-slave-1.0-SNAPSHOT.jar
Look at my github repo : https://github.com/johnsanthosh/image-service to figure out the right way to run this from a JAR.
That won't work if the string contains more than one match... try this:
echo "/x/y/z/x" | awk '{ gsub("/", "_") ; system( "echo " $0) }'
or better (if the echo
isn't a placeholder for something else):
echo "/x/y/z/x" | awk '{ gsub("/", "_") ; print $0 }'
In your case you want to make a copy of the value before changing it:
echo "/x/y/z/x" | awk '{ c=$0; gsub("/", "_", c) ; system( "echo " $0 " " c )}'
OAuth 2.0 spec doesn't define the part. But there could be couple of options:
When resource server gets the token in the Authz Header then it calls the validate/introspect API on Authz server to validate the token. Here Authz server might validate it either from using DB Store or verifying the signature and certain attributes. As part of response, it decodes the token and sends the actual data of token along with remaining expiry time.
Authz Server can encrpt/sign the token using private key and then publickey/cert can be given to Resource Server. When resource server gets the token, it either decrypts/verifies signature to verify the token. Takes the content out and processes the token. It then can either provide access or reject.
I think this works:
$(document).ready(function(){
// Hide (collapse) the toggle containers on load
$(".toggle_container").hide();
// Switch the "Open" and "Close" state per click then
// slide up/down (depending on open/close state)
$("h2.trigger").click(function(){
$(this).toggleClass("active").next().slideToggle("slow");
return false; // Prevent the browser jump to the link anchor
});
});
Use OleDB, you can create, read, and edit excel files pretty easily. Read the MSDN docs for more info:

You could explicitly create a DatetimeIndex
when initializing the dataframe. Assuming your data is in string format
data = [
('2015-09-25 00:46', '71.925000'),
('2015-09-25 00:47', '71.625000'),
('2015-09-25 00:48', '71.333333'),
('2015-09-25 00:49', '64.571429'),
('2015-09-25 00:50', '72.285714'),
]
index, values = zip(*data)
frame = pd.DataFrame({
'values': values
}, index=pd.DatetimeIndex(index))
print(frame.index.minute)
When you assign a function to a variable you don't use the () but simply the name of the function.
In your case given def x(): ...
, and variable silly_var
you would do something like this:
silly_var = x
and then you can call the function either with
x()
or
silly_var()
Is NDEBUG standard?
Yes it is a standard macro with the semantic "Not Debug" for C89, C99, C++98, C++2003, C++2011, C++2014 standards. There are no _DEBUG
macros in the standards.
C++2003 standard send the reader at "page 326" at "17.4.2.1 Headers" to standard C.
That NDEBUG is similar as This is the same as the Standard C library.
In C89 (C programmers called this standard as standard C) in "4.2 DIAGNOSTICS" section it was said
http://port70.net/~nsz/c/c89/c89-draft.html
If NDEBUG is defined as a macro name at the point in the source file where is included, the assert macro is defined simply as
#define assert(ignore) ((void)0)
If look at the meaning of _DEBUG
macros in Visual Studio
https://msdn.microsoft.com/en-us/library/b0084kay.aspx
then it will be seen, that this macro is automatically defined by your ?hoice of language runtime library version.
Install the additional module tablefunc
once per database, which provides the function crosstab()
. Since Postgres 9.1 you can use CREATE EXTENSION
for that:
CREATE EXTENSION IF NOT EXISTS tablefunc;
CREATE TABLE tbl (
section text
, status text
, ct integer -- "count" is a reserved word in standard SQL
);
INSERT INTO tbl VALUES
('A', 'Active', 1), ('A', 'Inactive', 2)
, ('B', 'Active', 4), ('B', 'Inactive', 5)
, ('C', 'Inactive', 7); -- ('C', 'Active') is missing
crosstab(text)
with 1 input parameter:
SELECT *
FROM crosstab(
'SELECT section, status, ct
FROM tbl
ORDER BY 1,2' -- needs to be "ORDER BY 1,2" here
) AS ct ("Section" text, "Active" int, "Inactive" int);
Returns:
Section | Active | Inactive ---------+--------+---------- A | 1 | 2 B | 4 | 5 C | 7 | -- !!
C
: the value 7
is filled in for the first column. Sometimes, this behavior is desirable, but not for this use case.crosstab(text, text)
with 2 input parameters:
SELECT *
FROM crosstab(
'SELECT section, status, ct
FROM tbl
ORDER BY 1,2' -- could also just be "ORDER BY 1" here
, $$VALUES ('Active'::text), ('Inactive')$$
) AS ct ("Section" text, "Active" int, "Inactive" int);
Returns:
Section | Active | Inactive ---------+--------+---------- A | 1 | 2 B | 4 | 5 C | | 7 -- !!
Note the correct result for C
.
The second parameter can be any query that returns one row per attribute matching the order of the column definition at the end. Often you will want to query distinct attributes from the underlying table like this:
'SELECT DISTINCT attribute FROM tbl ORDER BY 1'
That's in the manual.
Since you have to spell out all columns in a column definition list anyway (except for pre-defined crosstabN()
variants), it is typically more efficient to provide a short list in a VALUES
expression like demonstrated:
$$VALUES ('Active'::text), ('Inactive')$$)
Or (not in the manual):
$$SELECT unnest('{Active,Inactive}'::text[])$$ -- short syntax for long lists
I used dollar quoting to make quoting easier.
You can even output columns with different data types with crosstab(text, text)
- as long as the text representation of the value column is valid input for the target type. This way you might have attributes of different kind and output text
, date
, numeric
etc. for respective attributes. There is a code example at the end of the chapter crosstab(text, text)
in the manual.
db<>fiddle here
Pivot on Multiple Columns using Tablefunc - also demonstrating mentioned "extra columns"
\crosstabview
in psqlPostgres 9.6 added this meta-command to its default interactive terminal psql. You can run the query you would use as first crosstab()
parameter and feed it to \crosstabview
(immediately or in the next step). Like:
db=> SELECT section, status, ct FROM tbl \crosstabview
Similar result as above, but it's a representation feature on the client side exclusively. Input rows are treated slightly differently, hence ORDER BY
is not required. Details for \crosstabview
in the manual. There are more code examples at the bottom of that page.
Related answer on dba.SE by Daniel Vérité (the author of the psql feature):
The previously accepted answer is outdated.
The variant of the function crosstab(text, integer)
is outdated. The second integer
parameter is ignored. I quote the current manual:
crosstab(text sql, int N)
...Obsolete version of
crosstab(text)
. The parameterN
is now ignored, since the number of value columns is always determined by the calling query
Needless casting and renaming.
It fails if a row does not have all attributes. See safe variant with two input parameters above to handle missing attributes properly.
ORDER BY
is required in the one-parameter form of crosstab()
. The manual:
In practice the SQL query should always specify
ORDER BY 1,2
to ensure that the input rows are properly ordered
You can use the following syntax:
#include <map>
std::map<char, char> my_map = {
{ 'A', '1' },
{ 'B', '2' },
{ 'C', '3' }
};

Maybe it is the case that you have your path in couple of lines, you used enter to make it? If so, then part of you paths might look like that "/\nData/" instead of "/Data/", which causes the problem. Just set it to be in one line and issue is solved!
I had a similar issue. I had an image and wanted to reduce the transparency and have a black background behind the image. Instead of reducing the opacity or creating a black background or any secondary div I set a linear-gradient to the image all on one line:
background: linear-gradient(to bottom, rgba(0, 0, 0, 0.8) 0%, rgba(0, 0, 0, 0.8) 100%), url("/img/picture.png");

onEndReached={this.handleLoadMore}
onEndReachedThreshold={1}

removeClippedSubviews={true}
**keyExtractor={ (item, index) => index }**
/>
.....
my main problem was (KeyExtractor) i was not using it like this . not working : keyExtractor={ (item) => item.ID} after i changed to this it worked like charm i hope this helps someone.
If you have a .nupkg file and just need the .dll file all you have to do is change the extension to .zip and find the lib directory.
You can try this:
$('#studentTypeCheck').is(":checked");
In my opinion the accepted answer is in most cases an overkill.
The cause of the error is often mismatch of BEGIN and COMMIT as clearly stated by the error. This means using:
Begin
Begin
-- your query here
End
commit
instead of
Begin Transaction
Begin
-- your query here
End
commit
omitting Transaction after Begin causes this error!
This one works for me:

</form>
This link can be helpful:
Instead of this:
CheckboxList1.Items[i].value;
Try This:
CheckboxList1.Items[i].ToString();
It worked for me :)
Array and Object is passed as pass by reference or pass by value based on these two condition.
if you are changing value of that Object or array with new Object or Array then it is pass by Value.
object1 = {item: "car"};
array1=[1,2,3];
here you are assigning new object or array to old one.you are not changing the value of property of old object.so it is pass by value.
if you are changing a property value of an object or array then it is pass by Reference.
object1.item= "car";
array1[0]=9;
here you are changing a property value of old object.you are not assigning new object or array to old one.so it is pass by reference.
Code
function passVar(object1, object2, number1) {
object1.key1= "laptop";
object2 = {
key2: "computer"
};
number1 = number1 + 1;
}
var object1 = {
key1: "car"
};
var object2 = {
key2: "bike"
};
var number1 = 10;
passVar(object1, object2, number1);
console.log(object1.key1);
console.log(object2.key2);
console.log(number1);
Output: -
laptop

You'd better use CSS for this:
td{
background-color:black;
color:white;
}
td:hover{
background-color:white;
color:black;
}
If you want to use these styles for only a specific set of elements, you should give your td
a class (or an ID, if it's the only element which'll have that style).
Example :
<td class="whiteHover"></td>
.whiteHover{
/* Same style as above */
}
Here's a reference on MDN for :hover
pseudo class.
I am breaking the news to you. You CAN'T send an email with JavaScript per se.
Based on the context of the OP's question, my answer above does not hold true anymore as pointed out by @KennyEvitt in the comments. Looks like you can use JavaScript as an SMTP client.
However, I have not digged deeper to find out if it's secure & cross-browser compatible enough. So, I can neither encourage nor discourage you to use it. Use at your own risk.
As I said in comment your crystaldecisions.reportappserver.commlayer.dll
is not copied / present on your server. So for this you have to manually copy the dll and paste into you Bin
folder
To copy a DLL
from visual studio project follow the steps
1.Expand your Project's References hierarchy (Project should not be in debug mod)
2.Right Click on Particular
Dll
(in your casecrystaldecisions.reportappserver.commlayer.dll
) and select Properties and set 'Copy Local' attribute to TRUE3 Build your project. The Dll should be there in your
BIN
Folder.
This is an example of a good one and also an example of why you would never want to write one. It is a Fowler / Noll / Vo (FNV) Hash which is equal parts computer science genius and pure voodoo:
unsigned fnv_hash_1a_32 ( void *key, int len ) {
unsigned char *p = key;
unsigned h = 0x811c9dc5;
int i;
for ( i = 0; i < len; i++ )
h = ( h ^ p[i] ) * 0x01000193;
return h;
}
unsigned long long fnv_hash_1a_64 ( void *key, int len ) {
unsigned char *p = key;
unsigned long long h = 0xcbf29ce484222325ULL;
int i;
for ( i = 0; i < len; i++ )
h = ( h ^ p[i] ) * 0x100000001b3ULL;
return h;
}
Edit:
Now java 9 has factory Methods for Immutable List, Set, Map and Map.Entry .
In Java SE 8 and earlier versions, We can use Collections class utility methods like unmodifiableXXX to create Immutable Collection objects.
However these Collections.unmodifiableXXX methods are very tedious and verbose approach. To overcome those shortcomings, Oracle corp has added couple of utility methods to List, Set and Map interfaces.
Now in java 9 :- List and Set interfaces have “of()” methods to create an empty or no-empty Immutable List or Set objects as shown below:
Empty List Example
List immutableList = List.of();
Non-Empty List Example
List immutableList = List.of("one","two","three");
Another option to check your xpath is to use selenium IDE.
I bet the onchange
is getting fired after the onselect
, essentially re-enabling the select.
I'd recommend you implement only the onchange
, inspect which option has been selected, and enable or disabled based on that.
To get the value of the selected option use:
document.getElementById("mySelect").options[document.getElementById("mySelect").selectedIndex].value
Which will yield .. nothing since you haven't specified a value for each option .. :(
<select id="mySelect" onChange="enable();">
<option onSelect="disable();" value="no">No</option>
<option onSelect="enable();" value="yes">Yes</option>
</select>
Now it will yield "yes"
or "no"
You just need to create your own class inherited from parent. Place an ImageView on that, and on the mousedown and mouse up events just change the images of the ImageView.
public class ImageButton extends Parent {
private static final Image NORMAL_IMAGE = ...;
private static final Image PRESSED_IMAGE = ...;
private final ImageView iv;
public ImageButton() {
this.iv = new ImageView(NORMAL_IMAGE);
this.getChildren().add(this.iv);
this.iv.setOnMousePressed(new EventHandler<MouseEvent>() {
public void handle(MouseEvent evt) {
iv.setImage(PRESSED_IMAGE);
}
});
// TODO other event handlers like mouse up
}
}
You need to make a class library and not a Console Application. The console application is translated into an .exe
whereas the class library will then be compiled into a dll
which you can reference in your windows project.
The java.sql.Timestamp class has no format. Its toString method generates a String with a format.
Do not conflate a date-time object with a String that may represent its value. A date-time object can parse strings and generate strings but is not itself a string.
First convert from the troubled old legacy date-time classes to java.time classes. Use the new methods added to the old classes.
Instant instant = mySqlDate.toInstant() ;
Lose the fraction of a second you don't want.
instant = instant.truncatedTo( ChronoUnit.Seconds );
Assign the time zone to adjust from UTC used by Instant.
ZoneId z = ZoneId.of( "America/Montreal" ) ;
ZonedDateTime zdt = instant.atZone( z );
Generate a String close to your desired output. Replace its T
in the middle with a SPACE.
DateTimeFormatter f = DateTimeFormatter.ISO_LOCAL_DATE_TIME ;
String output = zdt.format( f ).replace( "T" , " " );

Below method can be used for copying the message:-
export function copyTextAreaToClipBoard(message: string) {
const cleanText = message.replace(/<\/?[^>]+(>|$)/g, '');
const x = document.createElement('TEXTAREA') as HTMLTextAreaElement;
x.value = cleanText;
document.body.appendChild(x);
x.select();
document.execCommand('copy');
document.body.removeChild(x);
}
By default git push
updates all the remote branches. But you can configure git to update only the current branch to it's upstream.
git config push.default upstream
It means git will update only the current (checked out) branch when you do git push.
Other valid options are:
nothing
: Do not push anything (error out) unless a refspec is explicitly given. This is primarily meant for people who want to avoid mistakes by always being explicit.matching
: Push all branches having the same name on both ends. (default option prior to Ver 1.7.11) upstream
: Push the current branch to its upstream
branch. This mode only makes sense if you are pushing to the same repository you would normally pull from (i.e. central workflow). No need to have the same name for local and remote branch.tracking
: Deprecated, use upstream
instead.current
: Push the current branch to the remote branch of the same name on the receiving end. Works in both central and non-central workflows.simple
: [available since Ver 1.7.11] in centralized workflow, work like upstream
with an added safety to refuse to push if the upstream branch’s name is different from the local one. When pushing to a remote that is different from the remote you normally pull from, work as current
. This is the safest option and is suited for beginners. This mode has become the default in Git 2.0.Another alternative is the following, although not the cleanest as it assumes the image to be the only element in a container, such as in this case:
<header class="siteHeader">
<img src="img" class="siteLogo" />
</header>
You can then use the container as a mask with the desired size, and surround the image with a negative margin to move it into the right position:
.siteHeader{
width: 50px;
height: 50px;
overflow: hidden;
}
.siteHeader .siteLogo{
margin: -100px;
}
Demo can be seen in this JSFiddle.
Only seems to work in IE>9, and probably all significant versions of all other browsers.
If your web page has jquery in your page, then you can do it writing on chrome developers console:
$.get(
"somepage.php",
{paramOne : 1, paramX : 'abc'},
function(data) {
alert('page content: ' + data);
}
);
Its jquery way of doing it!
Try This Code, it will capitalize first character of all words.
- set addTextChangedListener for EditText view
edt_text.addTextChangedListener(watcher);
- Add TextWatcher
TextWatcher watcher = new TextWatcher() {
int mStart = 0;
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
mStart = start + count;
}
@Override
public void afterTextChanged(Editable s) {
String input = s.toString();
String capitalizedText;
if (input.length() < 1)
capitalizedText = input;
else if (input.length() > 1 && input.contains(" ")) {
String fstr = input.substring(0, input.lastIndexOf(" ") + 1);
if (fstr.length() == input.length()) {
capitalizedText = fstr;
} else {
String sstr = input.substring(input.lastIndexOf(" ") + 1);
sstr = sstr.substring(0, 1).toUpperCase() + sstr.substring(1);
capitalizedText = fstr + sstr;
}
} else
capitalizedText = input.substring(0, 1).toUpperCase() + input.substring(1);
if (!capitalizedText.equals(edt_text.getText().toString())) {
edt_text.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
@Override
public void afterTextChanged(Editable s) {
edt_text.setSelection(mStart);
edt_text.removeTextChangedListener(this);
}
});
edt_text.setText(capitalizedText);
}
}
};
Because Option 2 creates a new List
reference, and then creates an n
element array from the List
(option 1 perfectly sizes the output array). However, first you need to fix the off by one bug. Use <
(not <=
). Like,
String[] out = new String[n];
for(int i = 0; i < n; i++) {
out[i] = in.get(i);
}
Building on @Tim's example to make a self-contained method:
import java.io.BufferedReader;
import java.io.File;
import java.io.InputStreamReader;
import java.util.ArrayList;
public class Shell {
/** Returns null if it failed for some reason.
*/
public static ArrayList<String> command(final String cmdline,
final String directory) {
try {
Process process =
new ProcessBuilder(new String[] {"bash", "-c", cmdline})
.redirectErrorStream(true)
.directory(new File(directory))
.start();
ArrayList<String> output = new ArrayList<String>();
BufferedReader br = new BufferedReader(
new InputStreamReader(process.getInputStream()));
String line = null;
while ( (line = br.readLine()) != null )
output.add(line);
//There should really be a timeout here.
if (0 != process.waitFor())
return null;
return output;
} catch (Exception e) {
//Warning: doing this is no good in high quality applications.
//Instead, present appropriate error messages to the user.
//But it's perfectly fine for prototyping.
return null;
}
}
public static void main(String[] args) {
test("which bash");
test("find . -type f -printf '%T@\\\\t%p\\\\n' "
+ "| sort -n | cut -f 2- | "
+ "sed -e 's/ /\\\\\\\\ /g' | xargs ls -halt");
}
static void test(String cmdline) {
ArrayList<String> output = command(cmdline, ".");
if (null == output)
System.out.println("\n\n\t\tCOMMAND FAILED: " + cmdline);
else
for (String line : output)
System.out.println(line);
}
}
(The test example is a command that lists all files in a directory and its subdirectories, recursively, in chronological order.)
By the way, if somebody can tell me why I need four and eight backslashes there, instead of two and four, I can learn something. There is one more level of unescaping happening than what I am counting.
Edit: Just tried this same code on Linux, and there it turns out that I need half as many backslashes in the test command! (That is: the expected number of two and four.) Now it's no longer just weird, it's a portability problem.
You wrote """I assume that means the HTML contains some wrongly-formed attempt at unicode somewhere."""
The HTML is NOT expected to contain any kind of "attempt at unicode", well-formed or not. It must of necessity contain Unicode characters encoded in some encoding, which is usually supplied up front ... look for "charset".
You appear to be assuming that the charset is UTF-8 ... on what grounds? The "\xA0" byte that is shown in your error message indicates that you may have a single-byte charset e.g. cp1252.
If you can't get any sense out of the declaration at the start of the HTML, try using chardet to find out what the likely encoding is.
Why have you tagged your question with "regex"?
Update after you replaced your whole question with a non-question:
html = urllib.urlopen(link).read()
# html refers to a str object. To get unicode, you need to find out
# how it is encoded, and decode it.
html.encode("utf8","ignore")
# problem 1: will fail because html is a str object;
# encode works on unicode objects so Python tries to decode it using
# 'ascii' and fails
# problem 2: even if it worked, the result will be ignored; it doesn't
# update html in situ, it returns a function result.
# problem 3: "ignore" with UTF-n: any valid unicode object
# should be encodable in UTF-n; error implies end of the world,
# don't try to ignore it. Don't just whack in "ignore" willy-nilly,
# put it in only with a comment explaining your very cogent reasons for doing so.
# "ignore" with most other encodings: error implies that you are mistaken
# in your choice of encoding -- same advice as for UTF-n :-)
# "ignore" with decode latin1 aka iso-8859-1: error implies end of the world.
# Irrespective of error or not, you are probably mistaken
# (needing e.g. cp1252 or even cp850 instead) ;-)
You should use reflect.DeepEqual()
DeepEqual is a recursive relaxation of Go's == operator.
DeepEqual reports whether x and y are “deeply equal,” defined as follows. Two values of identical type are deeply equal if one of the following cases applies. Values of distinct types are never deeply equal.
Array values are deeply equal when their corresponding elements are deeply equal.
Struct values are deeply equal if their corresponding fields, both exported and unexported, are deeply equal.
Func values are deeply equal if both are nil; otherwise they are not deeply equal.
Interface values are deeply equal if they hold deeply equal concrete values.
Map values are deeply equal if they are the same map object or if they have the same length and their corresponding keys (matched using Go equality) map to deeply equal values.
Pointer values are deeply equal if they are equal using Go's == operator or if they point to deeply equal values.
Slice values are deeply equal when all of the following are true: they are both nil or both non-nil, they have the same length, and either they point to the same initial entry of the same underlying array (that is, &x[0] == &y[0]) or their corresponding elements (up to length) are deeply equal. Note that a non-nil empty slice and a nil slice (for example, []byte{} and []byte(nil)) are not deeply equal.
Other values - numbers, bools, strings, and channels - are deeply equal if they are equal using Go's == operator.
This should work for you ...
int myInt= ((data)(((object[])(e.AddedItems))[0])).kid;
Just change the first line as follows :
include ActionView::Helpers
that will make it works.
UPDATE: For Rails 3 use:
ActionController::Base.helpers.sanitize(str)
Credit goes to lornc's answer
The following code works
<html>
<head>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
function AddRow()
{
$('#myTable').append('<tr><td>test 2</td></tr>')
}
</script>
<title></title>
</head>
<body>
<input type="button" id="btnAdd" onclick="AddRow()"/>
<a href="">test</a>
<table id="myTable">
<tbody >
<tr>
<td>
test
</td>
</tr>
</tbody>
</table>
</body>
</html>
Note this will work as of jQuery 1.4 even if the table includes a <tbody>
element:
jQuery since version 1.4(?) automatically detects if the element you are trying to insert (using any of the append(), prepend(), before(), or after() methods) is a
<tr>
and inserts it into the first<tbody>
in your table or wraps it into a new<tbody>
if one doesn't exist.
Solution working with different types and with upper and lower cases.
For example, without the toLowerCase
statement, "Goodyear" will come before "doe" with an ascending sort. Run the code snippet at the bottom of my answer to view the different behaviors.
JSON DATA:
var people = [
{
"f_name" : "john",
"l_name" : "doe", // lower case
"sequence": 0 // int
},
{
"f_name" : "michael",
"l_name" : "Goodyear", // upper case
"sequence" : 1 // int
}];
JSON Sort Function:
function sortJson(element, prop, propType, asc) {
switch (propType) {
case "int":
element = element.sort(function (a, b) {
if (asc) {
return (parseInt(a[prop]) > parseInt(b[prop])) ? 1 : ((parseInt(a[prop]) < parseInt(b[prop])) ? -1 : 0);
} else {
return (parseInt(b[prop]) > parseInt(a[prop])) ? 1 : ((parseInt(b[prop]) < parseInt(a[prop])) ? -1 : 0);
}
});
break;
default:
element = element.sort(function (a, b) {
if (asc) {
return (a[prop].toLowerCase() > b[prop].toLowerCase()) ? 1 : ((a[prop].toLowerCase() < b[prop].toLowerCase()) ? -1 : 0);
} else {
return (b[prop].toLowerCase() > a[prop].toLowerCase()) ? 1 : ((b[prop].toLowerCase() < a[prop].toLowerCase()) ? -1 : 0);
}
});
}
}

sortJson(people , "l_name", "string", true);
sortJson(people , "sequence", "int", true);

using Aaron's answer, this can be the short & easiest solution:
function filterSelectList(selectListId, filterId)
{
var filter = $("#" + filterId).val().toUpperCase();
$("#" + selectListId + " option").each(function(i){
if ($(this).text.toUpperCase().includes(filter))
$(this).css("display", "block");
else
$(this).css("display", "none");
});
};
You can actually simplify this by removing the v-on
directives:
<input type="radio" name="optionsRadios" id="optionsRadios1" value="1" v-model="srStatus">
And use the watch
method to listen for the change:
new Vue ({
el: "#app",
data: {
cases: [
{ name: 'case A', status: '1' },
{ name: 'case B', status: '0' },
{ name: 'case C', status: '1' }
],
activeCases: [],
srStatus: ''
},
watch: {
srStatus: function(val, oldVal) {
for (var i = 0; i < this.cases.length; i++) {
if (this.cases[i].status == val) {
this.activeCases.push(this.cases[i]);
alert("Fired! " + val);
}
}
}
}
});
In oracle an empty varchar2 and null are treated the same, and your observations show that.
when you write:
select * from table where a = '';
its the same as writing
select * from table where a = null;
and not a is null
which will never equate to true, so never return a row. same on the insert, a NOT NULL means you cant insert a null or an empty string (which is treated as a null)
In combination of answers of @Cassian and @Hllitec and from https://stackoverflow.com/a/42706309/1001717 here my solution, where I put (only!) the checksum value into a variable for further processing:
for /f "delims=" %i in ('certutil -v -hashfile myPackage.nupkg SHA256 ^| find /i /v "sha256" ^| find /i /v "certutil"') do set myVar=%i
To test the output you can add a piped echo command with the var:
for /f "delims=" %i in ('certutil -v -hashfile myPackage.nupkg SHA256 ^| find /i /v "sha256" ^| find /i /v "certutil"') do set myVar=%i | echo %myVar%
A bit off-topic, but FYI: I used this before uploading my NuGet package to Artifactory. BTW. as alternative you can use JFrog CLI, where checksum is calculated automatically.
New features have been added to MATLAB recently:
String arrays were introduced in R2016b (as Budo and gnovice already mentioned):
String arrays store pieces of text and provide a set of functions for working with text as data. You can index into, reshape, and concatenate strings arrays just as you can with arrays of any other type.
In addition, starting in R2017a, you can create a string using double quotes ""
.
Therefore if your MATLAB version is >= R2017a, the following will do:
for i = 1:3
Names(i) = "Sample Text";
end
Check the output:
>> Names
Names =
1×3 string array
"Sample Text" "Sample Text" "Sample Text"
No need to deal with cell arrays anymore.
This error is coming because some process is already running on 8081 port. Stop that process and then run your command, it will run your code. For this first list all the process which are using this port by typing
lsof -i :8081
This command will list the process id (PID) of the process and then kill the node process by using
kill -9 <PID>
Here PID is the process id of the node process.
The jquery.numeric plugin works well for me too.
The only thing I dislike has to do with intuitiveness. Keypresses get 'disallowed' without any feedback to the user, who might get paranoid or wonder whether his keyboard is broken.
I added a second callback to the plugin to make simple feedback on blocked input possible:
$('#someInput').numeric(
null, // default config
null, // no validation onblur callback
function(){
// for every blocked keypress:
$(this).effect("pulsate", { times:2 }, 100);
}
);
Just an example (using jQuery UI), of course. Any simple visual feedback would help.
Your code is working just fine, you have to declare javscript method before DOM ready.
For IBM Db2 its LENGTH, not LEN:
SELECT MAX(LENGTH(Desc)) FROM table_name;
We have that problem quite often, but only with references to C++/CLI projects from C# projects. It's obviously a bug deep down in Visual Studio that Microsoft decided not to fix, because it's 'too complex' and they promised an overhaul of the C++ build system which is now targeted for Visual Studio 2010.
That was some time ago, and maybe the fix even went into Visual Studio 2008; I didn't follow up on it any more. However, our typical workaround was
You should never need to modify the path directly, either through environment variables or sys.path
. Whether you use the os (ex. apt-get
), or pip
in a virtualenv, packages will be installed to a location already on the path.
In your example, GNU Radio is installed to the system Python 2's standard site-packages
location, which is already in the path. Pointing PyCharm at the correct interpreter is enough; if it isn't there is something else wrong that isn't apparent. It may be that /usr/bin/python
does not point to the same interpreter that GNU Radio was installed in; try pointing specifically at the python2.7
binary. Or, PyCharm used to be somewhat bad at detecting packages; File > Invalidate Caches > Invalidate and Restart
would tell it to rescan.
This answer will cover how you should set up a project environment, install packages in different scenarios, and configure PyCharm. I refer multiple times to the Python Packaging User Guide, written by the same group that maintains the official Python packaging tools.
The correct way to develop a Python application is with a virtualenv. Packages and version are installed without affecting the system or other projects. PyCharm has a built-in interface to create a virtualenv and install packages. Or you can create it from the command line and then point PyCharm at it.
$ cd MyProject
$ python2 -m virtualenv env
$ . env/bin/activate
$ pip install -U pip setuptools # get the latest versions
$ pip install flask # install other packages
In your PyCharm project, go to File > Settings > Project > Project Interpreter
. If you used virtualenvwrapper
or PyCharm to create the env, then it should show up in the menu. If not, click the gear, choose Add Local
, and locate the Python binary in the env. PyCharm will display all the packages in the selected env.
In some cases, such as with GNU Radio, there is no package to install with pip
, the package was installed system-wide when you install the rest of GNU Radio (ex. apt-get install gnuradio
). In this case, you should still use a virtualenv, but you'll need to make it aware of this system package.
$ python2 -m virtualenv --system-site-packages env
Unfortunately it looks a little messy, because all system packages will now appear in your env, but they are just links, you can still safely install or upgrade packages without affecting the system.
In some cases, you will have multiple local packages you're developing, and will want one project to use the other package. In this case you might think you have to add the local package to the other project's path, but this is not the case. You should install your package in development mode. All this requires is adding a setup.py
file to your package, which will be required anyway to properly distribute and deploy the package later.
Minimal setup.py
for your first project:
from setuptools import setup, find_packages
setup(
name='mypackage',
version='0.1',
packages=find_packages(),
)
Then install it in your second project's env:
$ pip install -e /path/to/first/project
Found this thread while I was looking for a solution to the exact problem described in the original post. None of the answers met my situation entirely, however. Brody's answer was pretty close. Here is my situation and solution I found to it.
I have two ILists of the same type returned by NHibernate and have emerged the two IList into one, hence the need for sorting.
Like Brody said I implemented an ICompare on the object (ReportFormat) which is the type of my IList:
public class FormatCcdeSorter:IComparer<ReportFormat>
{
public int Compare(ReportFormat x, ReportFormat y)
{
return x.FormatCode.CompareTo(y.FormatCode);
}
}
I then convert the merged IList to an array of the same type:
ReportFormat[] myReports = new ReportFormat[reports.Count]; //reports is the merged IList
Then sort the array:
Array.Sort(myReports, new FormatCodeSorter());//sorting using custom comparer
Since one-dimensional array implements the interface System.Collections.Generic.IList<T>
, the array can be used just like the original IList.
The solution is in the link that you provided in your question:
datetime.combine(date.today(), time()) + timedelta(hours=1)
Full example:
from datetime import date, datetime, time, timedelta
dt = datetime.combine(date.today(), time(23, 55)) + timedelta(minutes=30)
print dt.time()
Output:
00:25:00
Perl really only has three types: scalars, arrays, and hashes. And even that distinction is arguable. ;) The way each variable is treated depends on what you do with it:
% perl -e "print 5.4 . 3.4;"
5.43.4
% perl -e "print '5.4' + '3.4';"
8.8
for (var key in myMap) {
if (myMap.hasOwnProperty(key)) {
console.log("key =" + key);
console.log("value =" + myMap[key]);
}
}
In javascript, every object has a bunch of built-in key-value pairs that have meta-information. When you loop through all the key-value pairs for an object you're looping through them too. The use of hasOwnProperty() filters these out.
? public makes it accessible across the other classes. You can use it without instantiate of the class or using any object.
? static makes it uniform value across all the class instances. It ensures that you don't waste memory creating many of the same thing if it will be the same value for all the objects.
? final makes it non-modifiable value. It's a "constant" value which is same across all the class instances and cannot be modified.
Coarse-grained and Fine-grained both think about optimizing a number of servicess. But the difference is in the level. I like to explain with an example, you will understand easily.
Fine-grained: For example, I have 100 services like findbyId, findbyCategry, findbyName...... so on. Instead of that many services why we can not provide find(id, category, name....so on). So this way we can reduce the services. This is just an example, but the goal is how to optimize the number of services.
Coarse-grained: For example, I have 100 clients, each client have their own set of 100 services. So I have to provide 100*100 total services. It is very much difficult. Instead of that what I do is, I identify all common services which apply to most of the clients as one service set and remaining separately. For example in 100 services 50 services are common. So I have to manage 100*50 + 50 only.
Let's go over the basics: "Accessor" and "Mutator" are just fancy names fot a getter and a setter. A getter, "Accessor", returns a class's variable or its value. A setter, "Mutator", sets a class variable pointer or its value.
So first you need to set up a class with some variables to get/set:
public class IDCard
{
private String mName;
private String mFileName;
private int mID;
}
But oh no! If you instantiate this class the default values for these variables will be meaningless. B.T.W. "instantiate" is a fancy word for doing:
IDCard test = new IDCard();
So - let's set up a default constructor, this is the method being called when you "instantiate" a class.
public IDCard()
{
mName = "";
mFileName = "";
mID = -1;
}
But what if we do know the values we wanna give our variables? So let's make another constructor, one that takes parameters:
public IDCard(String name, int ID, String filename)
{
mName = name;
mID = ID;
mFileName = filename;
}
Wow - this is nice. But stupid. Because we have no way of accessing (=reading) the values of our variables. So let's add a getter, and while we're at it, add a setter as well:
public String getName()
{
return mName;
}
public void setName( String name )
{
mName = name;
}
Nice. Now we can access mName
. Add the rest of the accessors and mutators and you're now a certified Java newbie.
Good luck.

Let's understand in simple words
Note: These keys have more depth as a concept but this is good to start.
I assume that you're running a Linux, and you're using gEdit to edit your files. In the /etc/nginx/sites-enabled
, it may have left a temp file e.g. default~
(watch the ~
).
Depending on your editor, the file could be named .save
or something like it. Just run $ ls -lah
to see which files are unintended to be there and remove them (Thanks @Tisch for this).
Delete this file, and it will solve your problem.
check this code:
CREATE TRIGGER trig_Update_Employee ON [EmployeeResult] FOR INSERT AS Begin
Insert into Employee (Name, Department)
Select Distinct i.Name, i.Department
from Inserted i
Left Join Employee e on i.Name = e.Name and i.Department = e.Department
where e.Name is null
End
Use a Macro.
Macro>Start Recording
Use the keyboard to make your changes in a repeatable manner e.g.
home>type "able">end>down arrow>home
Then go back to the menu and click stop recording then run a macro multiple times.
That should do it and no regex based complications!
Vim's <leader>
key is a way of creating a namespace for commands you want to define. Vim already maps most keys and combinations of Ctrl + (some key), so <leader>(some key)
is where you (or plugins) can add custom behavior.
For example, if you find yourself frequently deleting exactly 3 words and 7 characters, you might find it convenient to map a command via nmap <leader>d 3dw7x
so that pressing the leader key followed by d will delete 3 words and 7 characters. Because it uses the leader key as a prefix, you can be (relatively) assured that you're not stomping on any pre-existing behavior.
The default key for <leader>
is \
, but you can use the command :let mapleader = ","
to remap it to another key (,
in this case).
Usevim's page on the leader key has more information.
The problem is that you forgot to import os. Add this line of code:
import os
And everything should be fine. Hope this helps!
I've created a little Powershell function to emulate MSDOS pause
. This handles whether running Powershell ISE or non ISE. (ReadKey
does not work in powershell ISE). When running Powershell ISE, this function opens a Windows MessageBox
. This can sometimes be confusing, because the MessageBox
does not always come to the forefront. Anyway, here it goes:
Usage:
pause "Press any key to continue"
Function definition:
Function pause ($message)
{
# Check if running Powershell ISE
if ($psISE)
{
Add-Type -AssemblyName System.Windows.Forms
[System.Windows.Forms.MessageBox]::Show("$message")
}
else
{
Write-Host "$message" -ForegroundColor Yellow
$x = $host.ui.RawUI.ReadKey("NoEcho,IncludeKeyDown")
}
}
If you have perl installed, then perl -i -n -e"print unless m{(ERROR|REFERENCE)}"
should do the trick.
This is an old question, but I'm going to add the fix for my particular issue (Spring Boot, JPA using Hibernate, SQL Server 2014) since it doesn't exactly match the other answers included here:
I had a foreign key, e.g. my_id = '12345', but the value in the referenced column was my_id = '12345 '. It had an extra space at the end which hibernate didn't like. I removed the space, fixed the part of my code that was allowing this extra space, and everything works fine.
Hard to believe adding a custom icon is so complicated. I found a similar solution to those posted above, but for me, I could not get the icon to display until I added the viewBox info, which I got directly from opening the SVG in a text editor.
//customIcon.js
import React from "react";
import {ReactComponent as ImportedSVG} from "path/to/myIcon.svg";
import { SvgIcon } from '@material-ui/core';
function CustomIcon() {
return(
<SvgIcon component={ImportedSVG} viewBox="0 0 384 512"/>
)
}
export default CustomIcon;
I also ran into an error with namespaces and had to clean up the SVG before it would work, following advice from this post
Using Spring's StringUtils
:
org.springframework.util.StringUtils.capitalize(someText);
If you're already using Spring anyway, this avoids bringing in another framework.
To expand upon Pavel Minaev's original comment - The GUI for Visual Studio supports relative references with the assumption that your .sln is the root of the relative reference. So if you have a solution C:\myProj\myProj.sln
, any references you add in subfolders of C:\myProj\
are automatically added as relative references.
To add a relative reference in a separate directory, such as C:/myReferences/myDLL.dll
, do the following:
Edit the < HintPath > to be equal to
<HintPath>..\..\myReferences\myDLL.dll</HintPath>
This now references C:\myReferences\myDLL.dll
.
Hope this helps.
Just do a
SELECT COUNT(*) FROM table;
You can specify conditions with a Where after that
SELECT COUNT(*) FROM table WHERE eye_color='brown';
Use a Spannable String
String s= "Hello Everyone";
SpannableString ss1= new SpannableString(s);
ss1.setSpan(new RelativeSizeSpan(2f), 0,5, 0); // set size
ss1.setSpan(new ForegroundColorSpan(Color.RED), 0, 5, 0);// set color
TextView tv= (TextView) findViewById(R.id.textview);
tv.setText(ss1);
Snap shot
You can split string using space and add span to the string you require.
String s= "Hello Everyone";
String[] each = s.split(" ");
Now apply span
to the string
and add the same to textview
.
Javascript sort of has the idea of 'truthiness' and 'falsiness'. If a variable has a value then, generally 9as you will see) it has 'truthiness' - null, or no value tends to 'falsiness'. The snippets below might help:
var temp1;
if ( temp1 )... // false
var temp2 = true;
if ( temp2 )... // true
var temp3 = "";
if ( temp3 ).... // false
var temp4 = "hello world";
if ( temp4 )... // true
Hopefully that helps?
Also, its worth checking out these videos from Douglas Crockford

People hate on tables for non-tabular data, but what you're asking for is exactly what tables are good at. <table width="100%">
Made some modification on Andrew's solution and update the code to Swift 3:
This code now use UITextView as self
and able to inherit its original font, font size and text color
Note: toHexString()
is extension from here
extension UITextView {
func setAttributedStringFromHTML(_ htmlCode: String, completionBlock: @escaping (NSAttributedString?) ->()) {
let inputText = "\(htmlCode)<style>body { font-family: '\((self.font?.fontName)!)'; font-size:\((self.font?.pointSize)!)px; color: \((self.textColor)!.toHexString()); }</style>"
guard let data = inputText.data(using: String.Encoding.utf16) else {
print("Unable to decode data from html string: \(self)")
return completionBlock(nil)
}
DispatchQueue.main.async {
if let attributedString = try? NSAttributedString(data: data, options: [NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType], documentAttributes: nil) {
self.attributedText = attributedString
completionBlock(attributedString)
} else {
print("Unable to create attributed string from html string: \(self)")
completionBlock(nil)
}
}
}
}
Example usage:
mainTextView.setAttributedStringFromHTML("<i>Hello world!</i>") { _ in }
Sometimes we know in advance that the value stored in a given integer variable will always be positive-when it is being used to only count things, for example. In such a case we can declare the variable to be unsigned, as in, unsigned int num student;
. With such a declaration, the range of permissible integer values (for a 32-bit compiler) will shift from the range -2147483648 to +2147483647 to range 0 to 4294967295. Thus, declaring an integer as unsigned almost doubles the size of the largest possible value that it can otherwise hold.
So yes, you should prefer the shadowPath property for performance, but also: From the header file of CALayer.shadowPath
Specifying the path explicitly using this property will usually * improve rendering performance, as will sharing the same path * reference across multiple layers
A lesser known trick is sharing the same reference across multiple layers. Of course they have to use the same shape, but this is common with table/collection view cells.
I don't know why it gets faster if you share instances, i'm guessing it caches the rendering of the shadow and can reuse it for other instances in the view. I wonder if this is even faster with
For basic data retrieval I would be going for Linq without hesitation.
Since moving to Linq I've found the following advantages:
There is also another approach without the use of DomXPath
or Zend_Dom_Query
.
Based on dav's original function, I wrote the following function that returns all the children of the parent node whose tag and class match the parameters.
function getElementsByClass(&$parentNode, $tagName, $className) {
$nodes=array();
$childNodeList = $parentNode->getElementsByTagName($tagName);
for ($i = 0; $i < $childNodeList->length; $i++) {
$temp = $childNodeList->item($i);
if (stripos($temp->getAttribute('class'), $className) !== false) {
$nodes[]=$temp;
}
}
return $nodes;
}
suppose you have a variable $html
the following HTML:
<html>
<body>
<div id="content_node">
<p class="a">I am in the content node.</p>
<p class="a">I am in the content node.</p>
<p class="a">I am in the content node.</p>
</div>
<div id="footer_node">
<p class="a">I am in the footer node.</p>
</div>
</body>
</html>
use of getElementsByClass
is as simple as:
$dom = new DOMDocument('1.0', 'utf-8');
$dom->loadHTML($html);
$content_node=$dom->getElementById("content_node");
$div_a_class_nodes=getElementsByClass($content_node, 'div', 'a');//will contain the three nodes under "content_node".
You can pass the ng-model value through the ng-change function as a parameter:
<select
ng-model="blisterPackTemplateSelected"
data-ng-options="blisterPackTemplate as blisterPackTemplate.name for blisterPackTemplate in blisterPackTemplates"
ng-change="changedValue(blisterPackTemplateSelected)">
<option value="">Select Account</option>
</select>
It's a bit difficult to know your scenario without seeing it, but this should work.

One thing that you need to be aware of when reflecting on private members is that if your application is running in medium trust (as, for instance, when you are running on a shared hosting environment), it won't find them -- the BindingFlags.NonPublic option will simply be ignored.
If you also want it to be a command you can reference without remembering the arguments, you could simply alias it:
alias df-gb='df -BG'
So if you type:
df-gb
into a terminal, you'll get your intended output of the disk usage in GB.
EDIT: or even use just df -h
to get it in a standard, human readable format.

you just make a list of lists like so:

results[0].Add("this is a string"); //adds a string to the first list

The jsqrcode library by Lazarsoft is now working perfectly using just HTML5, i.e. getUserMedia

GCC 4.9 introduces a newer C++ ABI version than your system libstdc++ has, so you need to tell the loader to use this newer version of the library by adding that path to LD_LIBRARY_PATH
. Unfortunately, I cannot tell you straight off where the libstdc++ so for your GCC 4.9 installation is located, as this depends on how you configured GCC. So you need something in the style of:
export LD_LIBRARY_PATH=/home/user/lib/gcc-4.9.0/lib:/home/user/lib/boost_1_55_0/stage/lib:$LD_LIBRARY_PATH
Note the actual path may be different (there might be some subdirectory hidden under there, like `x86_64-unknown-linux-gnu/4.9.0´ or similar).
An ObservableCollection
works essentially like a regular collection except that it implements
the interfaces:
As such it is very useful when you want to know when the collection has changed. An event is triggered that will tell the user what entries have been added/removed or moved.
More importantly they are very useful when using databinding on a form.
A Promise represents a proxy for a value not necessarily known when the promise is created. It allows you to associate handlers to an asynchronous action's eventual success value or failure reason. This lets asynchronous methods return values like synchronous methods: instead of the final value, the asynchronous method returns a promise of having a value at some point in the future.
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise
The deferred.promise()
method allows an asynchronous function to prevent other code from interfering with the progress or status of its internal request. The Promise exposes only the Deferred methods needed to attach additional handlers or determine the state (then, done, fail, always, pipe, progress, state and promise), but not ones that change the state (resolve, reject, notify, resolveWith, rejectWith, and notifyWith).
If target is provided, deferred.promise()
will attach the methods onto it and then return this object rather than create a new one. This can be useful to attach the Promise behavior to an object that already exists.
If you are creating a Deferred, keep a reference to the Deferred so that it can be resolved or rejected at some point. Return only the Promise object via deferred.promise() so other code can register callbacks or inspect the current state.
Simply we can say that a Promise represents a value that is not yet known where as a Deferred represents work that is not yet finished.

Save to database
user.first_name = u'Rytis'.encode('unicode_escape')
user.last_name = u'Slatkevicius'.encode('unicode_escape')
user.save()
>>> SUCCEED
print user.last_name

print user.last_name.decode('unicode_escape')

Is this the only method to save strings like that into a MySQL table and decode it before rendering to templates for display?
APC definitely. It's written by the PHP guys, so even though it might not share the highest speeds, you can bet on the fact it's the highest quality.
Plus you get some other nifty features I use all the time (http://www.php.net/apc).
Unfortunately, the MinGW-w64 installer you used sometimes has this issue. I myself am not sure about why this happens (I think it has something to do with Sourceforge URL redirection or whatever that the installer currently can't handle properly enough).
Anyways, if you're already planning on using MSYS2, there's no need for that installer.
Download MSYS2 from this page (choose 32 or 64-bit according to what version of Windows you are going to use it on, not what kind of executables you want to build, both versions can build both 32 and 64-bit binaries).
After the install completes, click on the newly created "MSYS2 Shell" option under either MSYS2 64-bit
or MSYS2 32-bit
in the Start menu. Update MSYS2 according to the wiki (although I just do a pacman -Syu
, ignore all errors and close the window and open a new one, this is not recommended and you should do what the wiki page says).
Install a toolchain
a) for 32-bit:
pacman -S mingw-w64-i686-gcc
b) for 64-bit:
pacman -S mingw-w64-x86_64-gcc
install any libraries/tools you may need. You can search the repositories by doing
pacman -Ss name_of_something_i_want_to_install
e.g.
pacman -Ss gsl
and install using
pacman -S package_name_of_something_i_want_to_install
e.g.
pacman -S mingw-w64-x86_64-gsl
and from then on the GSL library is automatically found by your MinGW-w64 64-bit compiler!
Open a MinGW-w64 shell:
a) To build 32-bit things, open the "MinGW-w64 32-bit Shell"
b) To build 64-bit things, open the "MinGW-w64 64-bit Shell"
Verify that the compiler is working by doing
gcc -v
If you want to use the toolchains (with installed libraries) outside of the MSYS2 environment, all you need to do is add <MSYS2 root>/mingw32/bin
or <MSYS2 root>/mingw64/bin
to your PATH
.
This solution works with Swift 4 (Xcode 9.2) and also with Swift 5 (Xcode 10.2.1+):
let fileManager = FileManager.default
let documentsURL = fileManager.urls(for: .documentDirectory, in: .userDomainMask)[0]
do {
let fileURLs = try fileManager.contentsOfDirectory(at: documentsURL, includingPropertiesForKeys: nil)
// process files
} catch {
print("Error while enumerating files \(documentsURL.path): \(error.localizedDescription)")
}
Here's a reusable FileManager extension that also lets you skip or include hidden files in the results:
import Foundation
extension FileManager {
func urls(for directory: FileManager.SearchPathDirectory, skipsHiddenFiles: Bool = true ) -> [URL]? {
let documentsURL = urls(for: directory, in: .userDomainMask)[0]
let fileURLs = try? contentsOfDirectory(at: documentsURL, includingPropertiesForKeys: nil, options: skipsHiddenFiles ? .skipsHiddenFiles : [] )
return fileURLs
}
}
// Usage
print(FileManager.default.urls(for: .documentDirectory) ?? "none")
You just need to put a small timeout event before doing .click()
like this :
setTimeout(function(){ $('#btn').click()}, 100);
I think pi has ssh server enabled by default. Mine have always worked out of the box. Depends which operating system version maybe.
Most of the time when it fails for me it is because the ip address has been changed. Perhaps you are pinging something else now? Also sometimes they just refuse to connect and need a restart.
try this
alert(document.getElementById("dropDownMenuKategorie").selectedIndex);
Since you're using Spring Boot, I assume you'd prefer to rely on Spring's auto configuration where possible. To add additional custom configuration like your interceptors, just provide a configuration or bean of WebMvcConfigurerAdapter
.
Here's an example of a config class:
@Configuration
public class WebMvcConfig extends WebMvcConfigurerAdapter {
@Autowired
HandlerInterceptor yourInjectedInterceptor;
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(...)
...
registry.addInterceptor(getYourInterceptor());
registry.addInterceptor(yourInjectedInterceptor);
// next two should be avoid -- tightly coupled and not very testable
registry.addInterceptor(new YourInterceptor());
registry.addInterceptor(new HandlerInterceptor() {
...
});
}
}
NOTE do not annotate this with @EnableWebMvc, if you want to keep Spring Boots auto configuration for mvc.

Use r.URL.Query()
when you appending to existing query, if you are building new set of params use the url.Values
struct like so

import (
"fmt"
"log"
"net/http"
"net/url"
"os"
)
func main() {
req, err := http.NewRequest("GET","http://api.themoviedb.org/3/tv/popular", nil)
if err != nil {
log.Print(err)
os.Exit(1)
}
// if you appending to existing query this works fine
q := req.URL.Query()
q.Add("api_key", "key_from_environment_or_flag")
q.Add("another_thing", "foo & bar")
// or you can create new url.Values struct and encode that like so
q := url.Values{}
q.Add("api_key", "key_from_environment_or_flag")
q.Add("another_thing", "foo & bar")
req.URL.RawQuery = q.Encode()
fmt.Println(req.URL.String())
// Output:
// http://api.themoviedb.org/3/tv/popularanother_thing=foo+%26+bar&api_key=key_from_environment_or_flag
}
You need to use the special hiveconf for variable substitution. e.g.
hive> set CURRENT_DATE='2012-09-16';
hive> select * from foo where day >= ${hiveconf:CURRENT_DATE}
similarly, you could pass on command line:
% hive -hiveconf CURRENT_DATE='2012-09-16' -f test.hql
Note that there are env and system variables as well, so you can reference ${env:USER}
for example.
To see all the available variables, from the command line, run
% hive -e 'set;'
or from the hive prompt, run
hive> set;
Update:
I've started to use hivevar variables as well, putting them into hql snippets I can include from hive CLI using the source
command (or pass as -i option from command line).
The benefit here is that the variable can then be used with or without the hivevar prefix, and allow something akin to global vs local use.
So, assume have some setup.hql which sets a tablename variable:
set hivevar:tablename=mytable;
then, I can bring into hive:
hive> source /path/to/setup.hql;
and use in query:
hive> select * from ${tablename}
or
hive> select * from ${hivevar:tablename}
I could also set a "local" tablename, which would affect the use of ${tablename}, but not ${hivevar:tablename}
hive> set tablename=newtable;
hive> select * from ${tablename} -- uses 'newtable'
vs
hive> select * from ${hivevar:tablename} -- still uses the original 'mytable'
Probably doesn't mean too much from the CLI, but can have hql in a file that uses source, but set some of the variables "locally" to use in the rest of the script.

The answer of slayton works fine. If you want to stop swiping like a monkey you can override a OnPageChangeListener with
@Override public void onPageScrollStateChanged(final int state) {
switch (state) {
case ViewPager.SCROLL_STATE_SETTLING:
mPager.setPagingEnabled(false);
break;
case ViewPager.SCROLL_STATE_IDLE:
mPager.setPagingEnabled(true);
break;
}
}
So you can only swipe side by side
Backspace and tab both move the cursor position. Neither is truly a 'printable' character.
Your code says:
To get the output you expect, you need printf("foo\b \tbar")
. Note the extra 'space'. That says:
Most of the time it is inappropriate to use tabs and backspace for formatting your program output. Learn to use printf()
formatting specifiers. Rendering of tabs can vary drastically depending on how the output is viewed.
This little script shows one way to alter your terminal's tab rendering. Tested on Ubuntu + gnome-terminal:
#!/bin/bash
tabs -8
echo -e "\tnormal tabstop"
for x in `seq 2 10`; do
tabs $x
echo -e "\ttabstop=$x"
done
tabs -8
echo -e "\tnormal tabstop"
Also see man setterm
and regtabs
.
And if you redirect your output or just write to a file, tabs will quite commonly be displayed as fewer than the standard 8 chars, especially in "programming" editors and IDEs.
So in otherwords:
printf("%-8s%s", "foo", "bar"); /* this will ALWAYS output "foo bar" */
printf("foo\tbar"); /* who knows how this will be rendered */
IMHO, tabs in general are rarely appropriate for anything. An exception might be generating output for a program that requires tab-separated-value input files (similar to comma separated value).
Backspace '\b'
is a different story... it should never be used to create a text file since it will just make a text editor spit out garbage. But it does have many applications in writing interactive command line programs that cannot be accomplished with format strings alone. If you find yourself needing it a lot, check out "ncurses", which gives you much better control over where your output goes on the terminal screen. And typically, since it's 2011 and not 1995, a GUI is usually easier to deal with for highly interactive programs. But again, there are exceptions. Like writing a telnet server or console for a new scripting language.
if( strpos( $url, $word ) !== false ) {
// Do something
}
If you want to see the array as an array, you can say
alert(JSON.stringify(aCustomers));
instead of all those document.write
s.
However, if you want to display them cleanly, one per line, in your popup, do this:
alert(aCustomers.join("\n"));
New answer (2016-04-20)
Using Spring Boot 1.3.1.RELEASE
New Step 1 - It is easy and less intrusive to add the following properties to the application.properties:
spring.mvc.throw-exception-if-no-handler-found=true
spring.resources.add-mappings=false
Much easier than modifying the existing DispatcherServlet instance (as below)! - JO'
If working with a full RESTful Application, it is very important to disable the automatic mapping of static resources since if you are using Spring Boot's default configuration for handling static resources then the resource handler will be handling the request (it's ordered last and mapped to /** which means that it picks up any requests that haven't been handled by any other handler in the application) so the dispatcher servlet doesn't get a chance to throw an exception.
New Answer (2015-12-04)
Using Spring Boot 1.2.7.RELEASE
New Step 1 - I found a much less intrusive way of setting the "throExceptionIfNoHandlerFound" flag. Replace the DispatcherServlet replacement code below (Step 1) with this in your application initialization class:
@ComponentScan()
@EnableAutoConfiguration
public class MyApplication extends SpringBootServletInitializer {
private static Logger LOG = LoggerFactory.getLogger(MyApplication.class);
public static void main(String[] args) {
ApplicationContext ctx = SpringApplication.run(MyApplication.class, args);
DispatcherServlet dispatcherServlet = (DispatcherServlet)ctx.getBean("dispatcherServlet");
dispatcherServlet.setThrowExceptionIfNoHandlerFound(true);
}
In this case, we're setting the flag on the existing DispatcherServlet, which preserves any auto-configuration by the Spring Boot framework.
One more thing I've found - the @EnableWebMvc annotation is deadly to Spring Boot. Yes, that annotation enables things like being able to catch all the controller exceptions as described below, but it also kills a LOT of the helpful auto-configuration that Spring Boot would normally provide. Use that annotation with extreme caution when you use Spring Boot.
Original Answer:
After a lot more research and following up on the solutions posted here (thanks for the help!) and no small amount of runtime tracing into the Spring code, I finally found a configuration that will handle all Exceptions (not Errors, but read on) including 404s.
Step 1 - tell SpringBoot to stop using MVC for "handler not found" situations. We want Spring to throw an exception instead of returning to the client a view redirect to "/error". To do this, you need to have an entry in one of your configuration classes:
// NEW CODE ABOVE REPLACES THIS! (2015-12-04)
@Configuration
public class MyAppConfig {
@Bean // Magic entry
public DispatcherServlet dispatcherServlet() {
DispatcherServlet ds = new DispatcherServlet();
ds.setThrowExceptionIfNoHandlerFound(true);
return ds;
}
}
The downside of this is that it replaces the default dispatcher servlet. This hasn't been a problem for us yet, with no side effects or execution problems showing up. If you're going to do anything else with the dispatcher servlet for other reasons, this is the place to do them.
Step 2 - Now that spring boot will throw an exception when no handler is found, that exception can be handled with any others in a unified exception handler:
@EnableWebMvc
@ControllerAdvice
public class ServiceExceptionHandler extends ResponseEntityExceptionHandler {
@ExceptionHandler(Throwable.class)
@ResponseBody
ResponseEntity<Object> handleControllerException(HttpServletRequest req, Throwable ex) {
ErrorResponse errorResponse = new ErrorResponse(ex);
if(ex instanceof ServiceException) {
errorResponse.setDetails(((ServiceException)ex).getDetails());
}
if(ex instanceof ServiceHttpException) {
return new ResponseEntity<Object>(errorResponse,((ServiceHttpException)ex).getStatus());
} else {
return new ResponseEntity<Object>(errorResponse,HttpStatus.INTERNAL_SERVER_ERROR);
}
}
@Override
protected ResponseEntity<Object> handleNoHandlerFoundException(NoHandlerFoundException ex, HttpHeaders headers, HttpStatus status, WebRequest request) {
Map<String,String> responseBody = new HashMap<>();
responseBody.put("path",request.getContextPath());
responseBody.put("message","The URL you have reached is not in service at this time (404).");
return new ResponseEntity<Object>(responseBody,HttpStatus.NOT_FOUND);
}
...
}
Keep in mind that I think the "@EnableWebMvc" annotation is significant here. It seems that none of this works without it. And that's it - your Spring boot app will now catch all exceptions, including 404s, in the above handler class and you may do with them as you please.
One last point - there doesn't seem to be a way to get this to catch thrown Errors. I have a wacky idea of using aspects to catch errors and turn them into Exceptions that the above code can then deal with, but I have not yet had time to actually try implementing that. Hope this helps someone.
Any comments/corrections/enhancements will be appreciated.
Groovy doesn't have an import keyword like typical scripting languages that will do a literal include of another file's contents (alluded to here: Does groovy provide an include mechanism?).
Because of its object/class oriented nature, you have to "play games" to make things like this work. One possibility is to make all your utility functions static (since you said they don't use objects) and then perform a static import in the context of your executing shell. Then you can call these methods like "global functions".
Another possibility would be using a Binding object (http://groovy.codehaus.org/api/groovy/lang/Binding.html) while creating your Shell and binding all the functions you want to the methods (the downside here would be having to enumerate all methods in the binding but you could perhaps use reflection). Yet another solution would be to override methodMissing(...)
in the delegate object assigned to your shell which allows you to basically do dynamic dispatch using a map or whatever method you'd like.
Several of these methods are demonstrated here: http://www.nextinstruction.com/blog/2012/01/08/creating-dsls-with-groovy/. Let me know if you want to see an example of a particular technique.
Well, I have a similar project where users upload files onto the server. Under my point of view, option a) is the best solution due to it's more flexible. What you must do is storing images in a protected folder classified by subdirectories. The main directory must be set up by the administrator as the content must no run scripts (very important) and (read, write) protected for not be accesible in http request.
I hope this helps you.
Ehcache is a pretty good solution for this and has a way to peek (getQuiet() is the method) such that it doesn't update the idle timestamp. Internally, Ehcache is implemented with a set of maps, kind of like ConcurrentHashMap, so it has similar kinds of concurrency benefits.
I adopted the @Jotne solution and works perfectly! For example for mongodb server in my NAS
#! /bin/bash
case "$(pidof mongod | wc -w)" in
0) echo "Restarting mongod:"
mongod --config mongodb.conf
;;
1) echo "mongod already running"
;;
esac
You don't need the assignment, list.append(x)
will always append x
to a
and therefore there's no need te redefine a
.
a = []
for i in range(5):
a.append(i)
print(a)
is all you need. This works because list
s are mutable.
Also see the docs on data structures.
Refering to MySql documentation,
CREATE DATABASE creates a database with the given name. To use this statement, you need the CREATE privilege for the database. CREATE SCHEMA is a synonym for CREATE DATABASE as of MySQL 5.0.2.
I have created a library to batch delete or update records with a round trip on EF Core 5.
Sample code as follows:
await ctx.DeleteRangeAsync(b => b.Price > n || b.AuthorName == "zack yang");
await ctx.BatchUpdate()
.Set(b => b.Price, b => b.Price + 3)
.Set(b=>b.AuthorName,b=>b.Title.Substring(3,2)+b.AuthorName.ToUpper())
.Set(b => b.PubTime, b => DateTime.Now)
.Where(b => b.Id > n || b.AuthorName.StartsWith("Zack"))
.ExecuteAsync();

One way to do this is to insert a dummy column with the sums in order to sort:
In [10]: sum_B_over_A = df.groupby('A').sum().B

A
bar 0.253652
baz -2.829711
foo 0.551376
Name: B
in [12]: df['sum_B_over_A'] = df.A.apply(sum_B_over_A.get_value)
In [13]: df
Out[13]:

You can revert all your files under your working directory and index by typing following this command
git reset --hard <SHAsum of your commit>
You can also type
git reset --hard HEAD #your current head point
or
git reset --hard HEAD^ #your previous head point

Instead of having a fat APK file, I would like to use just the armeabi files and remove the armeabi-v7a folder.
The opposite is a much better strategy. If you have minSdkVersion
to 14 and upload your apk to the play store, you'll notice you'll support the same number of devices whether you support armeabi
or not. Therefore, there are no devices with Android 4 or higher which would benefit from armeabi
at all.
This is probably why the Android NDK doesn't even support armeabi
anymore as per revision r17b. [source]
A weak entity is one that can only exist when owned by another one. For example: a ROOM can only exist in a BUILDING. On the other hand, a TIRE might be considered as a strong entity because it also can exist without being attached to a CAR.
0xe0434352 is the SEH code for a CLR exception. If you don't understand what that means, stop and read A Crash Course on the Depths of Win32™ Structured Exception Handling. So your process is not handling a CLR exception. Don't shoot the messenger, KERNELBASE.DLL is just the unfortunate victim. The perpetrator is MyApp.exe.
There should be a minidump of the crash in DrWatson folders with a full stack, it will contain everything you need to root cause the issue.
I suggest you wire up, in your myapp.exe code, AppDomain.UnhandledException
and Application.ThreadException
, as appropriate.
When you try to execute a program in unix (one with the executable bit set), the operating system will look at the first few bytes of the file. These form the so-called "magic number", which can be used to decide the format of the program and how to execute it.
#!
corresponds to the magic number 0x2321 (look it up in an ascii table). When the system sees that the magic number, it knows that it is dealing with a text script and reads until the next \n
(there is a limit, but it escapes me atm). Having identified the interpreter (the first argument after the shebang) it will call the interpreter.
Other files also have magic numbers. Try looking at a bitmap (.BMP) file via less
and you will see the first two characters are BM
. This magic number denotes that the file is indeed a bitmap.
The simplest way is to use the JsonPrimitive
class, which derives from JsonElement
, as shown below:
JsonElement element = new JsonPrimitive(yourString);
JsonObject result = element.getAsJsonObject();
First thing, you don't need to write
ResultSet rs = stmt.executeQuery(sql);
just write
ResultSet rs = stmt.executeQuery();
The above mentioned syntax is used for Statements not for PreparedStatement.
Second thing, rs.next() checks if the result set contains any values or not. It returns a boolean value as well as it moves the cursor to the first value in the result set because initially it is at BEFORE FIRST Position. So if you want to access first value in result set, you need to write rs.next().
EUROPE:
declare @d datetime;
set @d=getdate();
set @dow=((datepart(dw,@d) + @@DATEFIRST-2) % 7+1);
Just declare a variable like k
or m
or any other you want, now just add this piece of code at the end of your program
k=input("press close to exit")
Here I just assumed k
as variable to pause the program, you can use any variable you like.
To revert modified files:
sudo svn revert
svn status|grep "^ *M" | sed -e 's/^ *M *//'
Yeah, I know this is an 8 year-old question, but I was told that it was possible to statically link against a shared-object library and this was literally the top hit when I searched for more information about it.
To actually demonstrate that statically linking a shared-object library is not possible with ld
(gcc
's linker) -- as opposed to just a bunch of people insisting that it's not possible -- use the following gcc
command:
gcc -o executablename objectname.o -Wl,-Bstatic -l:libnamespec.so
(Of course you'll have to compile objectname.o
from sourcename.c
, and you should probably make up your own shared-object library as well. If you do, use -Wl,--library-path,.
so that ld can find your library in the local directory.)
The actual error you receive is:
/usr/bin/ld: attempted static link of dynamic object `libnamespec.so'
collect2: error: ld returned 1 exit status
Hope that helps.
Just Additional Info which took me long time to find.what if you were using the field name and not id for identifying the form field. You do it like this:
For radio button:
var inp= $('input:radio[name=PatientPreviouslyReceivedDrug]:checked').val();
For textbox:
var txt=$('input:text[name=DrugDurationLength]').val();
I just added a public repo with a ready to run out of the box server using Jetty and JDBC to get your project started.
Pull from github here: https://github.com/waf04/WAF-Simple-JAVA-HTTP-MYSQL-Server.git
Usage: If you're going to store information that you want to access on different web pages, you can use SessionState
If you want to store information that you want to access from the same page, then you can use Viewstate
Storage The Viewstate is stored within the page itself (in encrypted text), while the Sessionstate is stored in the server.
The SessionState will clear in the following conditions
The fastest MySQL
solution, without inner queries and without GROUP BY
:
SELECT m.* -- get the row that contains the max value
FROM topten m -- "m" from "max"
LEFT JOIN topten b -- "b" from "bigger"
ON m.home = b.home -- match "max" row with "bigger" row by `home`
AND m.datetime < b.datetime -- want "bigger" than "max"
WHERE b.datetime IS NULL -- keep only if there is no bigger than max
Explanation:
Join the table with itself using the home
column. The use of LEFT JOIN
ensures all the rows from table m
appear in the result set. Those that don't have a match in table b
will have NULL
s for the columns of b
.
The other condition on the JOIN
asks to match only the rows from b
that have bigger value on the datetime
column than the row from m
.
Using the data posted in the question, the LEFT JOIN
will produce this pairs:
+------------------------------------------+--------------------------------+
| the row from `m` | the matching row from `b` |
|------------------------------------------|--------------------------------|
| id home datetime player resource | id home datetime ... |
|----|-----|------------|--------|---------|------|------|------------|-----|
| 1 | 10 | 04/03/2009 | john | 399 | NULL | NULL | NULL | ... | *
| 2 | 11 | 04/03/2009 | juliet | 244 | NULL | NULL | NULL | ... | *
| 5 | 12 | 04/03/2009 | borat | 555 | NULL | NULL | NULL | ... | *
| 3 | 10 | 03/03/2009 | john | 300 | 1 | 10 | 04/03/2009 | ... |
| 4 | 11 | 03/03/2009 | juliet | 200 | 2 | 11 | 04/03/2009 | ... |
| 6 | 12 | 03/03/2009 | borat | 500 | 5 | 12 | 04/03/2009 | ... |
| 7 | 13 | 24/12/2008 | borat | 600 | 8 | 13 | 01/01/2009 | ... |
| 8 | 13 | 01/01/2009 | borat | 700 | NULL | NULL | NULL | ... | *
+------------------------------------------+--------------------------------+
Finally, the WHERE
clause keeps only the pairs that have NULL
s in the columns of b
(they are marked with *
in the table above); this means, due to the second condition from the JOIN
clause, the row selected from m
has the biggest value in column datetime
.

The solution is to set the proxy to "native" as below
Go to "Window-> Preferences -> General -> Network Connection" and change the Settings "Active Provider-> Native". It worked for me.
In your comment on @Kenneth's answer you're saying that ReadAsStringAsync()
is returning empty string.
That's because you (or something - like model binder) already read the content, so position of internal stream in Request.Content is on the end.
What you can do is this:
public static string GetRequestBody()
{
var bodyStream = new StreamReader(HttpContext.Current.Request.InputStream);
bodyStream.BaseStream.Seek(0, SeekOrigin.Begin);
var bodyText = bodyStream.ReadToEnd();
return bodyText;
}

Simply follow the instructions given here:
Example install:
sudo apt-get install python-software-properties python g++ make sudo add-apt-repository ppa:chris-lea/node.js sudo apt-get update sudo apt-get install nodejs
It installs current stable Node on the current stable Ubuntu. Quantal (12.10) users may need to install the software-properties-common package for the
add-apt-repository
command to work:sudo apt-get install software-properties-common
As of Node.js v0.10.0, the nodejs package from Chris Lea's repo includes both npm and nodejs-dev.
Don't give sudo apt-get install nodejs npm
. Just sudo apt-get install nodejs

Best is Enhanced Media Library plugin http://wordpress.org/plugins/enhanced-media-library/ It's adding as many category/ taxonomies you want. Works just great. You can filter media everywhere, plus have the categories in the menu choices, can be usefull also.
I personally was searching for something to let me compute the multiline string area, so I could determine if given area is big enough to print the string - with preserving specific font.
private static Hashtable hash = new Hashtable();
private Font font;
private LineBreakMeasurer lineBreakMeasurer;
private int start, end;
public PixelLengthCheck(Font font) {
this.font = font;
}
public boolean tryIfStringFits(String textToMeasure, Dimension areaToFit) {
AttributedString attributedString = new AttributedString(textToMeasure, hash);
attributedString.addAttribute(TextAttribute.FONT, font);
AttributedCharacterIterator attributedCharacterIterator =
attributedString.getIterator();
start = attributedCharacterIterator.getBeginIndex();
end = attributedCharacterIterator.getEndIndex();
lineBreakMeasurer = new LineBreakMeasurer(attributedCharacterIterator,
new FontRenderContext(null, false, false));
float width = (float) areaToFit.width;
float height = 0;
lineBreakMeasurer.setPosition(start);
while (lineBreakMeasurer.getPosition() < end) {
TextLayout textLayout = lineBreakMeasurer.nextLayout(width);
height += textLayout.getAscent();
height += textLayout.getDescent() + textLayout.getLeading();
}
boolean res = height <= areaToFit.getHeight();
return res;
}
I use a slightly modified version of the "if DEBUG" style of settings that Harper Shelby posted. Obviously depending on the environment (win/linux/etc.) the code might need to be tweaked a bit.
I was in the past using the "if DEBUG" but I found that occasionally I needed to do testing with DEUBG set to False. What I really wanted to distinguish if the environment was production or development, which gave me the freedom to choose the DEBUG level.
PRODUCTION_SERVERS = ['WEBSERVER1','WEBSERVER2',]
if os.environ['COMPUTERNAME'] in PRODUCTION_SERVERS:
PRODUCTION = True
else:
PRODUCTION = False
DEBUG = not PRODUCTION
TEMPLATE_DEBUG = DEBUG
# ...
if PRODUCTION:
DATABASE_HOST = '192.168.1.1'
else:
DATABASE_HOST = 'localhost'
I'd still consider this way of settings a work in progress. I haven't seen any one way to handling Django settings that covered all the bases and at the same time wasn't a total hassle to setup (I'm not down with the 5x settings files methods).
This code scrolls to the bottom but doesn't require that you wait each time. It'll continually scroll, and then stop at the bottom (or timeout)
from selenium import webdriver
import time
driver = webdriver.Chrome(executable_path='chromedriver.exe')
driver.get('https://example.com')
pre_scroll_height = driver.execute_script('return document.body.scrollHeight;')
run_time, max_run_time = 0, 1
while True:
iteration_start = time.time()
# Scroll webpage, the 100 allows for a more 'aggressive' scroll
driver.execute_script('window.scrollTo(0, 100*document.body.scrollHeight);')
post_scroll_height = driver.execute_script('return document.body.scrollHeight;')
scrolled = post_scroll_height != pre_scroll_height
timed_out = run_time >= max_run_time
if scrolled:
run_time = 0
pre_scroll_height = post_scroll_height
elif not scrolled and not timed_out:
run_time += time.time() - iteration_start
elif not scrolled and timed_out:
break
# closing the driver is optional
driver.close()
This is much faster than waiting 0.5-3 seconds each time for a response, when that response could take 0.1 seconds
The first answer works very well, but for ZERO / 0 it will format as .00
Hence the format #,##0.00 is working well for me. Always test different numbers such as 0 / 100 / 2334.30 and negative numbers before deploying to production system.
@momo's answer for Apache HttpClient, version 4.3.1 or later. I'm using JSON-Java
to build my JSON object:
JSONObject json = new JSONObject();
json.put("someKey", "someValue");
CloseableHttpClient httpClient = HttpClientBuilder.create().build();
try {
HttpPost request = new HttpPost("http://yoururl");
StringEntity params = new StringEntity(json.toString());
request.addHeader("content-type", "application/json");
request.setEntity(params);
httpClient.execute(request);
// handle response here...
} catch (Exception ex) {
// handle exception here
} finally {
httpClient.close();
}
The guaranteed one that I had working was something along these lines:
myModule.config(['$httpProvider', function($httpProvider) {
if (!$httpProvider.defaults.headers.common) {
$httpProvider.defaults.headers.common = {};
}
$httpProvider.defaults.headers.common["Cache-Control"] = "no-cache";
$httpProvider.defaults.headers.common.Pragma = "no-cache";
$httpProvider.defaults.headers.common["If-Modified-Since"] = "Mon, 26 Jul 1997 05:00:00 GMT";
}]);
I had to merge 2 of the above solutions in order to guarantee the correct usage for all methods, but you can replace common
with get
or other method i.e. put
, post
, delete
to make this work for different cases.
Set a breakpoint as usual. Right click it. Click Condition.
You should just use something like:
YourModel.update_all(
ActiveRecord::Base.send(:sanitize_sql_for_assignment, {:value => "'wow'"})
)
That would do the trick. Using the ActiveRecord::Base#send method to invoke the sanitize_sql_for_assignment makes the Ruby (at least the 1.8.7 version) skip the fact that the sanitize_sql_for_assignment is actually a protected method.
You could try using a NSDictionary for the params. The following will send the parameters correctly to a JSON server.
NSError *error;
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue:nil];
NSURL *url = [NSURL URLWithString:@"[JSON SERVER"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:60.0];
[request addValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request addValue:@"application/json" forHTTPHeaderField:@"Accept"];
[request setHTTPMethod:@"POST"];
NSDictionary *mapData = [[NSDictionary alloc] initWithObjectsAndKeys: @"TEST IOS", @"name",
@"IOS TYPE", @"typemap",
nil];
NSData *postData = [NSJSONSerialization dataWithJSONObject:mapData options:0 error:&error];
[request setHTTPBody:postData];
NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
}];
[postDataTask resume];
Hope this helps (I'm trying to sort a CSRF authenticity issue with the above - but it does send the params in the NSDictionary).
Just for completeness, here's a variant that uses print()
(works on Python 2.6-3.x):
from __future__ import print_function
try: from cStringIO import StringIO
except ImportError:
from io import StringIO
def to_int(nums, _s = StringIO()):
print(*nums, sep='', end='', file=_s)
s = _s.getvalue()
_s.truncate(0)
return int(s)
I've measured performance of @cdleary's functions. The results are slightly different.
Each function tested with the input list generated by:
def randrange1_10(digit_count): # same as @cdleary
return [random.randrange(1, 10) for i in xrange(digit_count)]
You may supply your own function via --sequence-creator=yourmodule.yourfunction
command-line argument (see below).
The fastest functions for a given number of integers in a list (len(nums) == digit_count
) are:
len(nums)
in 1..30
def _accumulator(nums):
tot = 0
for num in nums:
tot *= 10
tot += num
return tot
len(nums)
in 30..1000
def _map(nums):
return int(''.join(map(str, nums)))
def _imap(nums):
return int(''.join(imap(str, nums)))

In your Dockerfile
, you can use the verb EXPOSE
to expose multiple ports.
e.g.
EXPOSE 3000 80 443 22
You then would like to build an new image based on above Dockerfile
.
e.g.
docker build -t foo:tag .
Then you can use the -p
to map host port with the container port, as defined in above EXPOSE
of Dockerfile
.
e.g.
docker run -p 3001:3000 -p 23:22
In case you would like to expose a range of continuous ports, you can run docker like this:
docker run -it -p 7100-7120:7100-7120/tcp
This is how I solved the problem The menu closes a few seconds after mouse out (that if hover didn't fire),
//Set timer switch
$setM_swith=0;
$(function(){
$(".navbar-nav li a").click(function(event) {
if (!$(this).parent().hasClass('dropdown'))
$(".navbar-collapse").collapse('hide');
});
$(".navbar-collapse").mouseleave(function(){
$setM_swith=1;
setTimeout(function(){
if($setM_swith==1) {
$(".navbar-collapse").collapse('hide');
$setM_swith=0;}
}, 3000);
});
$(".navbar-collapse").mouseover(function() {
$setM_swith=0;
});
});
Beside of the inbuilt 'reindent' function, you can also install other plugins, such as SublimeAStyleFormatter and CodeFormatter. These plugins are better for their specify language.
You're asking a question about numeric comparisons, so regular expressions really have nothing to do with the issue. You don't need "multiple if
" statements to do it, either:
if (x >= 0.001 && x <= 0.009) {
// something
}
You could write yourself a "between()" function:
function between(x, min, max) {
return x >= min && x <= max;
}
// ...
if (between(x, 0.001, 0.009)) {
// something
}

Not being a numpy person, I took a shot with:
>>> import numpy as np
>>> import itertools
>>>
>>> a = np.array([1,2,3,4,5,6,7,8,9])
>>> index=[2,3,6]
>>> a = np.array(list(itertools.compress(a, [i not in index for i in range(len(a))])))
>>> a
array([1, 2, 5, 6, 8, 9])
According to my tests, this outperforms numpy.delete()
. I don't know why that would be the case, maybe due to the small size of the initial array?
python -m timeit -s "import numpy as np" -s "import itertools" -s "a = np.array([1,2,3,4,5,6,7,8,9])" -s "index=[2,3,6]" "a = np.array(list(itertools.compress(a, [i not in index for i in range(len(a))])))"
100000 loops, best of 3: 12.9 usec per loop
python -m timeit -s "import numpy as np" -s "a = np.array([1,2,3,4,5,6,7,8,9])" -s "index=[2,3,6]" "np.delete(a, index)"
10000 loops, best of 3: 108 usec per loop
That's a pretty significant difference (in the opposite direction to what I was expecting), anyone have any idea why this would be the case?
Even more weirdly, passing numpy.delete()
a list performs worse than looping through the list and giving it single indices.
python -m timeit -s "import numpy as np" -s "a = np.array([1,2,3,4,5,6,7,8,9])" -s "index=[2,3,6]" "for i in index:" " np.delete(a, i)"
10000 loops, best of 3: 33.8 usec per loop
Edit: It does appear to be to do with the size of the array. With large arrays, numpy.delete()
is significantly faster.
python -m timeit -s "import numpy as np" -s "import itertools" -s "a = np.array(list(range(10000)))" -s "index=[i for i in range(10000) if i % 2 == 0]" "a = np.array(list(itertools.compress(a, [i not in index for i in range(len(a))])))"
10 loops, best of 3: 200 msec per loop
python -m timeit -s "import numpy as np" -s "a = np.array(list(range(10000)))" -s "index=[i for i in range(10000) if i % 2 == 0]" "np.delete(a, index)"
1000 loops, best of 3: 1.68 msec per loop
Obviously, this is all pretty irrelevant, as you should always go for clarity and avoid reinventing the wheel, but I found it a little interesting, so I thought I'd leave it here.
This:
document.getElementById('myField').onblur();
works because your element (the <input>
) has an attribute called "onblur" whose value is a function. Thus, you can call it. You're not telling the browser to simulate the actual "blur" event, however; there's no event object created, for example.
Elements do not have a "blur" attribute (or "method" or whatever), so that's why the first thing doesn't work.

In case you are getting this in the eclipse IDE, even after setting the parameters
--launcher.XXMaxPermSize
, -XX:MaxPermSize
, etc, still if you are getting the same error, it most likely is that the eclipse is using a buggy version of JRE which would have been installed by some third party applications and set to default. These buggy versions do not pick up the PermSize parameters and so no matter whatever you set, you still keep getting these memory errors. So, in your eclipse.ini add the following parameters:
-vm <path to the right JRE directory>/<name of javaw executable>
Also make sure you set the default JRE in the preferences in the eclipse to the correct version of java.
