You can use box-sizing
css property, it's crossbrowser(ie8+, and all real browsers) and pretty good solution for such cases:
#childDiv{
box-sizing: border-box;
width: 100%; //or any percentage width you want
padding: 50px;
}
To go with thelost's Apache Commons answer: using guava-libraries (Google's general-purpose Java utility library which I would argue should now be on the classpath of any non-trivial Java project), this would use CharMatcher:
CharMatcher.is('0').trimLeadingFrom(inputString);
If you have:
enum Suit
{
Spades,
Hearts,
Clubs,
Diamonds
}
This:
foreach (var e in Enum.GetValues(typeof(Suit)))
{
Console.WriteLine(e.ToString() + " = " + (int)e);
}
Will output:
Spades = 0
Hearts = 1
Clubs = 2
Diamonds = 3
(int)99.99999
It will be 99. Casting a double to an int does not round, it'll discard the fraction part.
You need to subscribe to a SMS gateway. There are thousands of those (try searching with google) and they are usually not free. For example this one has support for PHP.
The place where each
can cause you problems is that it's a true, non-scoped iterator. By way of example:
while ( my ($key,$val) = each %a_hash ) {
print "$key => $val\n";
last if $val; #exits loop when $val is true
}
# but "each" hasn't reset!!
while ( my ($key,$val) = each %a_hash ) {
# continues where the last loop left off
print "$key => $val\n";
}
If you need to be sure that each
gets all the keys and values, you need to make sure you use keys
or values
first (as that resets the iterator). See the documentation for each.
I am writing a php extension and also encounter this problem. When i call an extern function with complicated parameters from my extension, this error pop up.
The reason is my not allocating memory for a parameter(char *) in the extern function. If you are writing same kind of extension, please pay attention to this.
Should this not work?

I had a bit of trouble with merging when trying to do Pete's steps. These are the steps I ended up with.
Use your OS to delete the .git
folder inside of the project folder that you want to commit. This will give you a clean slate to work with. This is also a good time to make a .gitignore
file inside the project folder. This can be a copy of the .gitignore
created when you created the repository on github.com. Doing this copy will avoid deleting it when you update the github.com repository.
Open Git Bash and navigate to the folder you just deleted the .git
folder from.
Run git init
. This sets up a local repository in the folder you're in.
Run git remote add [alias] https://github.com/[gitUserName]/[RepoName].git
. [alias] can be anything you want. The [alias] is meant to tie to the local repository, so the machine name works well for an [alias]. The URL can be found on github.com, along the top ensure that the HTTP button out of HTTP|SSH|Git Read-Only is clicked. The git://
URL didn't work for me.
Run git pull [alias] master
. This will update your local repository and avoid some merging conflicts.
Run git add .
Run git commit -m 'first code commit'
Run git push [alias] master
What if one of the values is negative? Wouldn't a better idea be:
double NextDouble(double min, double max)
{
if (min >= max)
throw new ArgumentOutOfRangeException();
return random.NextDouble() * (Math.Abs(max-min)) + min;
}
If you just want to run a function for testing purposes, you can use the Immediate Window in Access.
Press Ctrl + G
in the VBA editor to open it.
Then you can run your functions like this:
?YourFunction("parameter")
YourSub "parameter"
?variable
There is also at least one library for doing native threading from within Node.js: node-webworker-threads

This basically implements the Web Worker browser API for node.js.
In eclipse go to DDMS
under DDMS select Emulator Control ,which contains Telephony Status in telephony status contain data -->select Home , this will enable your internet connection ,if you want disable internet connection for Emulator then --->select None
(Note: This will enable internet connections only if you PC/laptop on which you are running your eclipse have active internet connections.)
think of operator as unary function: is_false(type value)
which returns true or false, depending on the exact implementation for specific type and value. Consider if statement to invoke such function implicitly, via syntactic sugar.
other possibility is that type has cast operator, which turns type into another type implicitly, in this case string to Boolean.
PHP does not expose such details, but C++ allows operator overloading which exposes fine details of operator implementation.
This should be equivalent to your current code, only a lot faster:
output <- matrix(unlist(z), ncol = 10, byrow = TRUE)
Initial question:
window.location.href.substr(0, window.location.href.indexOf('#'))
or
window.location.href.split('#')[0]
both will return the URL without the hash or anything after it.
With regards to your edit:
Any change to window.location
will trigger a page refresh. You can change window.location.hash
without triggering the refresh (though the window will jump if your hash matches an id on the page), but you can't get rid of the hash sign. Take your pick for which is worse...
MOST UP-TO-DATE ANSWER
The right answer on how to do it without sacrificing (either full reload or leaving the hash sign there) is down here. Leaving this answer here though with respect to being the original one in 2009 whereas the correct one which leverages new browser APIs was given 1.5 years later.

Just another viewpoint. Performing an "or" in Prolog can also be done with the "disjunct" operator or semi-colon:
registered(X, Y) :-
X = ct101; X = ct102; X = ct103.
For a fuller explanation:
This is the correct way:
To execute code that will only be available to the index page, we could use this syntax:
$(document).on('pageinit', "#index", function() {
...
});
Do it in the controller
$timeout(function(){
$scope.checked = true;
}, 1);
_x000D_
then remove ng-checked.
There is one little catch with the third approach. Since aggregate POMs (myproject/pom.xml) usually don't have parent at all, they do not share configuration. That means all those aggregate POMs will have only default repositories.
That is not a problem if you only use plugins from Central, however, this will fail if you run plugin using the plugin:goal format from your internal repository. For example, you can have foo-maven-plugin
with the groupId of org.example
providing goal generate-foo
. If you try to run it from the project root using command like mvn org.example:foo-maven-plugin:generate-foo
, it will fail to run on the aggregate modules (see compatibility note).
Several solutions are possible:
Not sure if this is relevant to your question but it might be relevant to someone else in the future: I had a similar error. Turned out that the df was empty (had zero rows) and that is what was causing the error in my command.
Use showWarnings = FALSE
:
dir.create(file.path(mainDir, subDir), showWarnings = FALSE)
setwd(file.path(mainDir, subDir))
dir.create()
does not crash if the directory already exists, it just prints out a warning. So if you can live with seeing warnings, there is no problem with just doing this:
dir.create(file.path(mainDir, subDir))
setwd(file.path(mainDir, subDir))
If you want to use optional arguments, but not named arguments, then this approach worked for me. I think this is much easier code to follow.
REM Get argument values. If not specified, use default values.
IF "%1"=="" ( SET "DatabaseServer=localhost" ) ELSE ( SET "DatabaseServer=%1" )
IF "%2"=="" ( SET "DatabaseName=MyDatabase" ) ELSE ( SET "DatabaseName=%2" )
REM Do work
ECHO Database Server = %DatabaseServer%
ECHO Database Name = %DatabaseName%

You can use the built-in class XAttribute, which handles the encoding automatically:
using System.Xml.Linq;
XDocument doc = new XDocument();
List<XAttribute> attributes = new List<XAttribute>();
attributes.Add(new XAttribute("key1", "val1&val11"));
attributes.Add(new XAttribute("key2", "val2"));
XElement elem = new XElement("test", attributes.ToArray());
doc.Add(elem);
string xmlStr = doc.ToString();
There is actually a (subtle) difference between the two. Imagine you have the following code in File1.cs:
// File1.cs
using System;
namespace Outer.Inner
{
class Foo
{
static void Bar()
{
double d = Math.PI;
}
}
}
Now imagine that someone adds another file (File2.cs) to the project that looks like this:
// File2.cs
namespace Outer
{
class Math
{
}
}
The compiler searches Outer
before looking at those using
directives outside the namespace, so it finds Outer.Math
instead of System.Math
. Unfortunately (or perhaps fortunately?), Outer.Math
has no PI
member, so File1 is now broken.
This changes if you put the using
inside your namespace declaration, as follows:
// File1b.cs
namespace Outer.Inner
{
using System;
class Foo
{
static void Bar()
{
double d = Math.PI;
}
}
}
Now the compiler searches System
before searching Outer
, finds System.Math
, and all is well.
Some would argue that Math
might be a bad name for a user-defined class, since there's already one in System
; the point here is just that there is a difference, and it affects the maintainability of your code.
It's also interesting to note what happens if Foo
is in namespace Outer
, rather than Outer.Inner
. In that case, adding Outer.Math
in File2 breaks File1 regardless of where the using
goes. This implies that the compiler searches the innermost enclosing namespace before it looks at any using
directive.

And the Application class should be like this
Application.java
package com.example;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
@SpringBootApplication
public class Application extends SpringBootServletInitializer {
/**
* Used when run as JAR
*/
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
/**
* Used when run as WAR
*/
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(Application.class);
}
}
And you can add a controller for testing MyController.java
package com.example;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class MyController {
@RequestMapping("/hi")
public @ResponseBody String hiThere(){
return "hello world!";
}
}
Then you can run the project in a tomcat 8 version and access the controller like this
If for some reason you are not able to add the project to tomcat do a right click in the project and then go to the Build Path->configure build path->Project Faces
make sure only this 3 are selected

I know this is a year old but I just came across it with the same problem. My problem was that I didn't have a constructor in my implementation file. I think the problem here could be the comment marks at the end of the header file after the #endif...
This is similar to the difference between
SELECT * FROM table_name and SELECT 1 FROM table_name.
If you do
SELECT 1 FROM table_name
it will give you the number 1 for each row in the table. So yes count(*)
and count(1)
will provide the same results as will count(8)
or count(column_name)
Delete Without Rebooting
The OP's question indeed has been answered extensively, including how to avoid rebooting through powershell, vbscript, or you name it.
However, if you need to stick to cmd commands only and don't have the luxury of being able to call powershell or vbscript, you could use the following approach:
rem remove from current cmd instance
SET FOOBAR=
rem remove from the registry if it's a user variable
REG delete HKCU\Environment /F /V FOOBAR
rem remove from the registry if it's a system variable
REG delete "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /F /V FOOBAR
rem tell Explorer.exe to reload the environment from the registry
SETX DUMMY ""
rem remove the dummy
REG delete HKCU\Environment /F /V DUMMY
So the magic here is that by using "setx" to assign something to a variable you don't need (in my example DUMMY), you force Explorer.exe to reread the variables from the registry, without needing powershell. You then clean up that dummy, and even though that one will stay in Explorer's environment for a little while longer, it will probably not harm anyone.
Or if after deleting variables you need to set new ones, then you don't even need any dummy. Just using SETX to set the new variables will automatically clear the ones you just removed from any new cmd tasks that might get started.
Background information: I just used this approach successfully to replace a set of user variables by system variables of the same name on all of the computers at my job, by modifying an existing cmd script. There are too many computers to do it manually, nor was it practical to copy extra powershell or vbscripts to all of them. The reason I urgently needed to replace user with system variables was that user variables get synchronized in roaming profiles (didn't think about that), so multiple machines using the same windows login but needing different values, got mixed up.
Yes, but you'll need to be using .NET 3.5 and C# 4.0 to get this functionality.

Important notice: the property (part of hibernate configuration, NOT part of logging framework config!)
hibernate.show_sql
controls the logging directly to STDOUT bypassing any logging framework (which you can recognize by the missing output formatting of the messages). If you use a logging framework like log4j, you should always set that property to false because it gives you no benefit at all.
That circumstance irritated me quite a long time because I never really cared about it until I tried to write some benchmark regarding Hibernate.
First you have to change the rendering property of the image to "Template Image" in the .xcassets folder. You can then just change the tint color property of the instance of your UIImageView like so:
imageView.tintColor = UIColor.whiteColor()
Change the field back to numeric and use ZEROFILL
to keep the zeros
or
use LPAD()
SELECT LPAD('1234567', 8, '0');
I would probably use something like this:
function generatePassword() {
var length = 8,
charset = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789",
retVal = "";
for (var i = 0, n = charset.length; i < length; ++i) {
retVal += charset.charAt(Math.floor(Math.random() * n));
}
return retVal;
}
That can then be extended to have the length and charset passed by a parameter.
A very interesting project is disruptor. It has a ringbuffer and is used from what I know in financial applications.
See here: code of ringbuffer
I checked both Guava's EvictingQueue and ArrayDeque.
ArrayDeque does not limit growth if it's full it will double size and hence is not precisely acting like a ringbuffer.
EvictingQueue does what it promises but internally uses a Deque to store things and just bounds memory.
Hence, if you care about memory being bounded ArrayDeque is not fullfilling your promise. If you care about object count EvictingQueue uses internal composition (bigger object size).
A simple and memory efficient one can be stolen from jmonkeyengine. verbatim copy

import numpy as np
hist, bin_edges = np.histogram([1, 1, 2, 2, 2, 2, 3], bins = range(5))
Below, hist
indicates that there are 0 items in bin #0, 2 in bin #1, 4 in bin #3, 1 in bin #4.
print(hist)

bin_edges
indicates that bin #0 is the interval [0,1), bin #1 is [1,2), ...,
bin #3 is [3,4).

or similar compat module as they tend to hide away what
is trying to be achieved.import sys
PY2 = sys.version_info.major == 2
# Check if string (lenient for byte-strings on Py2):
isinstance('abc', basestring if PY2 else str)
# Check if strictly a string (unicode-string):
isinstance('abc', unicode if PY2 else str)
# Check if either string (unicode-string) or byte-string:
isinstance('abc', basestring if PY2 else (str, bytes))
# Check for byte-string (Py3 and Py2.7):
isinstance('abc', bytes)
If you have the column and the sequence, you first need to populate a new key for all the existing rows. Assuming you don't care which key is assigned to which row
UPDATE table_name
SET new_pk_column = sequence_name.nextval;
Once that's done, you can create the primary key constraint (this assumes that either there is no existing primary key constraint or that you have already dropped the existing primary key constraint)
ALTER TABLE table_name
ADD CONSTRAINT pk_table_name PRIMARY KEY( new_pk_column )
If you want to generate the key automatically, you'd need to add a trigger
CREATE TRIGGER trigger_name
BEFORE INSERT ON table_name
FOR EACH ROW
BEGIN
:new.new_pk_column := sequence_name.nextval;
END;
If you are on an older version of Oracle, the syntax is a bit more cumbersome
CREATE TRIGGER trigger_name
BEFORE INSERT ON table_name
FOR EACH ROW
BEGIN
SELECT sequence_name.nextval
INTO :new.new_pk_column
FROM dual;
END;
It depends on where you're displaying the text. On the console or a textbox for example, \n will suffice. On a RichTextBox I think you need both.
Answer for MYSQL USERS:

After some investigation I wrote this:
import Foundation
struct Math {
private static var seeded = false
static func randomFractional() -> CGFloat {
if !Math.seeded {
let time = Int(NSDate().timeIntervalSinceReferenceDate)
srand48(time)
Math.seeded = true
}
return CGFloat(drand48())
}
}
Now you can just do Math.randomFraction()
to get random numbers [0..1[ without having to remember seeding first. Hope this helps someone :o)

The comments state the objective is to print to 2 decimal places.
There's a simple answer for Python 3:
>>> num=3.65
>>> "The number is {:.2f}".format(num)
'The number is 3.65'
or equivalently with f-strings (Python 3.6+):
>>> num = 3.65
>>> f"The number is {num:.2f}"
'The number is 3.65'
As always, the float value is an approximation:
>>> "{}".format(num)
'3.65'
>>> "{:.10f}".format(num)
'3.6500000000'
>>> "{:.20f}".format(num)
'3.64999999999999991118'
I think most use cases will want to work with floats and then only print to a specific precision.
Those that want the numbers themselves to be stored to exactly 2 decimal digits of precision, I suggest use the decimal type. More reading on floating point precision for those that are interested.
This is by far the best post for exporting to excel from SQL:
http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=49926
To quote from user madhivanan
,
Apart from using DTS and Export wizard, we can also use this query to export data from SQL Server2000 to Excel
Create an Excel file named testing having the headers same as that of table columns and use these queries
1 Export data to existing EXCEL file from SQL Server table
insert into OPENROWSET('Microsoft.Jet.OLEDB.4.0',
'Excel 8.0;Database=D:\testing.xls;',
'SELECT * FROM [SheetName$]') select * from SQLServerTable
2 Export data from Excel to new SQL Server table
select *
into SQLServerTable FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0',
'Excel 8.0;Database=D:\testing.xls;HDR=YES',
'SELECT * FROM [Sheet1$]')
3 Export data from Excel to existing SQL Server table (edited)
Insert into SQLServerTable Select * FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0',
'Excel 8.0;Database=D:\testing.xls;HDR=YES',
'SELECT * FROM [SheetName$]')
4 If you dont want to create an EXCEL file in advance and want to export data to it, use
EXEC sp_makewebtask
@outputfile = 'd:\testing.xls',
@query = 'Select * from Database_name..SQLServerTable',
@colheaders =1,
@FixedFont=0,@lastupdated=0,@resultstitle='Testing details'
(Now you can find the file with data in tabular format)
5 To export data to new EXCEL file with heading(column names), create the following procedure
create procedure proc_generate_excel_with_columns
(
@db_name varchar(100),
@table_name varchar(100),
@file_name varchar(100)
)
as
--Generate column names as a recordset
declare @columns varchar(8000), @sql varchar(8000), @data_file varchar(100)
select
@columns=coalesce(@columns+',','')+column_name+' as '+column_name
from
information_schema.columns
where
table_name=@table_name
select @columns=''''''+replace(replace(@columns,' as ',''''' as '),',',',''''')
--Create a dummy file to have actual data
select @data_file=substring(@file_name,1,len(@file_name)-charindex('\',reverse(@file_name)))+'\data_file.xls'
--Generate column names in the passed EXCEL file
set @sql='exec master..xp_cmdshell ''bcp " select * from (select '+@columns+') as t" queryout "'+@file_name+'" -c'''
exec(@sql)
--Generate data in the dummy file
set @sql='exec master..xp_cmdshell ''bcp "select * from '+@db_name+'..'+@table_name+'" queryout "'+@data_file+'" -c'''
exec(@sql)
--Copy dummy file to passed EXCEL file
set @sql= 'exec master..xp_cmdshell ''type '+@data_file+' >> "'+@file_name+'"'''
exec(@sql)
--Delete dummy file
set @sql= 'exec master..xp_cmdshell ''del '+@data_file+''''
exec(@sql)
After creating the procedure, execute it by supplying database name, table name and file path:
EXEC proc_generate_excel_with_columns 'your dbname', 'your table name','your file path'
Its a whomping 29 pages but that is because others show various other ways as well as people asking questions just like this one on how to do it.
Follow that thread entirely and look at the various questions people have asked and how they are solved. I picked up quite a bit of knowledge just skimming it and have used portions of it to get expected results.
To update single cells
A member also there Peter Larson posts the following: I think one thing is missing here. It is great to be able to Export and Import to Excel files, but how about updating single cells? Or a range of cells?
This is the principle of how you do manage that
update OPENROWSET('Microsoft.Jet.OLEDB.4.0',
'Excel 8.0;Database=c:\test.xls;hdr=no',

Vue
allows for you to specify a default prop
value and type
directly, by making props an object (see: https://vuejs.org/guide/components.html#Prop-Validation):
props: {
year: {
default: 2016,
type: Number
}
}
If the wrong type is passed then it throws an error and logs it in the console, here's the fiddle:
Following on Irfan's answer, I have the following XML configuration on OSX with .NET Core 2.1.300 which correctly logs and appends to a ./log
folder and also to the console. Note the log4net.config
must exist in the solution root (whereas in my case, my app root is a subfolder).
<?xml version="1.0" encoding="utf-8" ?>
<log4net>
<appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender" >
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date %-5level %logger - %message%newline" />
</layout>
</appender>
<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">

Another note, the traditional way of setting the XML up within app.config
did not work:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
</configSections>

For some reason, the log4net node was not found when accessing the XMLDocument via log4netConfig["log4net"]

What we do, is to create two tables for each multilingual object.
E.g. the first table contains only language-neutral data (primary key, etc.) and the second table contains one record per language, containing the localized data plus the ISO code of the language.
In some cases we add a DefaultLanguage field, so that we can fall-back to that language if no localized data is available for a specified language.
Example:
Table "Product":
----------------
ID : int
<any other language-neutral fields>
Table "ProductTranslations"
---------------------------
ID : int (foreign key referencing the Product)
Language : varchar (e.g. "en-US", "de-CH")
IsDefault : bit
ProductDescription : nvarchar
<any other localized data>
With this approach, you can handle as many languages as needed (without having to add additional fields for each new language).
Update (2014-12-14): please have a look at this answer, for some additional information about the implementation used to load multilingual data into an application.
If property name
does not work don't forget that id
still exists. This answer is for people who wants to target the id
here how you do.
$('input[id=element_id][value=element_value]').prop("checked",true);
Because property name
does not work for me. Make sure you don't surround id
and name
with double/single quotations.

I needed to copy all .md files from one directory into another, so here is what I did.
for i in **/*.md;do mkdir -p ../docs/"$i" && rm -r ../docs/"$i" && cp "$i" "../docs/$i" && echo "$i -> ../docs/$i"; done
Which is pretty hard to read, so lets break it down.
first cd into the directory with your files,
for i in **/*.md;
for each file in your pattern
mkdir -p ../docs/"$i"
make that directory in a docs folder outside of folder containing your files. Which creates an extra folder with the same name as that file.
rm -r ../docs/"$i"
remove the extra folder that is created as a result of mkdir -p
cp "$i" "../docs/$i"
Copy the actual file
echo "$i -> ../docs/$i"
Echo what you did

Enjoy!
I like this one. Simple, and you can have more than one parameter for each argument:
final Map<String, List<String>> params = new HashMap<>();
List<String> options = null;
for (int i = 0; i < args.length; i++) {
final String a = args[i];
if (a.charAt(0) == '-') {
if (a.length() < 2) {
System.err.println("Error at argument " + a);
return;
}
options = new ArrayList<>();
params.put(a.substring(1), options);
}
else if (options != null) {
options.add(a);
}
else {
System.err.println("Illegal parameter usage");
return;
}
}
For example:
-arg1 1 2 --arg2 3 4
System.out.print(params.get("arg1").get(0)); // 1
System.out.print(params.get("arg1").get(1)); // 2
System.out.print(params.get("-arg2").get(0)); // 3
System.out.print(params.get("-arg2").get(1)); // 4

row_indices, col_indices = temp1.nonzero()
temp1.data /= rows_sums_sqrt[row_indices]
temp2 = temp1.transpose()

Using following code, one can first check variable is set or not using @isset of laravel directive and then check that array is blank or not using @unless of laravel directive
@if(@isset($names))
@unless($names)
Array has no value
@else
Array has value
@foreach($names as $name)
{{$name}}
@endforeach
@endunless
@else
Not defined
@endif
To retrieve text of an auto generated span value just do this :
var al = $("#id-span-name").text();
alert(al);
Try this:
import re
mystr = 'This is a string, with words!'
wordList = re.sub("[^\w]", " ", mystr).split()
How it works:
From the docs :
re.sub(pattern, repl, string, count=0, flags=0)
Return the string obtained by replacing the leftmost non-overlapping occurrences of pattern in string by the replacement repl. If the pattern isn’t found, string is returned unchanged. repl can be a string or a function.
so in our case :
pattern is any non-alphanumeric character.
[\w] means any alphanumeric character and is equal to the character set [a-zA-Z0-9_]
a to z, A to Z , 0 to 9 and underscore.
so we match any non-alphanumeric character and replace it with a space .
and then we split() it which splits string by space and converts it to a list
so 'hello-world'
becomes 'hello world'
with re.sub
and then ['hello' , 'world']
after split()
let me know if any doubts come up.
If we need only one column to be numeric
yyz$b <- as.numeric(as.character(yyz$b))
But, if all the columns needs to changed to numeric
, use lapply
to loop over the columns and convert to numeric
by first converting it to character
class as the columns were factor
.
yyz[] <- lapply(yyz, function(x) as.numeric(as.character(x)))
Both the columns in the OP's post are factor
because of the string "n/a"
. This could be easily avoided while reading the file using na.strings = "n/a"
in the read.table/read.csv
or if we are using data.frame
, we can have character
columns with stringsAsFactors=FALSE
(the default is stringsAsFactors=TRUE
)
Regarding the usage of apply
, it converts the dataset to matrix
and matrix
can hold only a single class. To check the class
, we need
lapply(yyz, class)
Or
sapply(yyz, class)
Or check
str(yyz)
You add your ActionListener
twice to button
. So correct your code for button2
to
JButton button2 = new JButton("hello agin2");
panel.add(button2);
button2.addActionListener (new Action2());//note the button2 here instead of button
Furthermore, perform your Swing operations on the correct thread by using EventQueue.invokeLater
New method for an old question
It seems like in the answers provided the issue was always how the box border would either be visible on the left and right of the object or you'd have to inset it so far that it didn't shadow the whole length of the container properly.
This example uses the :after
pseudo element along with a linear gradient with transparency in order to put a drop shadow on a container that extends exactly to the sides of the element you wish to shadow.
Worth noting with this solution is that if you use padding on the element that you wish to drop shadow, it won't display correctly. This is because the after
pseudo element appends it's content directly after the elements inner content. So if you have padding, the shadow will appear inside the box. This can be overcome by eliminating padding on outer container (where the shadow applies) and using an inner container where you apply needed padding.
Example with padding and background color on the shadowed div:
If you want to change the depth of the shadow, simply increase the height
style in the after
pseudo element. You can also obviously darken, lighten, or change colors in the linear gradient styles.

Leonid Beschastny's answer works but I also had to convert ArrayBuffer to Buffer that is used in the Node's request
module. After uploading file to the server I had it in the same format that comes from the HTML5 FileAPI (I'm using Meteor). Full code below - maybe it will be helpful for others.
function toBuffer(ab) {
var buffer = new Buffer(ab.byteLength);
var view = new Uint8Array(ab);
for (var i = 0; i < buffer.length; ++i) {
buffer[i] = view[i];
}
return buffer;
}
var req = request.post(url, function (err, resp, body) {
if (err) {
console.log('Error!');
} else {
console.log('URL: ' + body);
}
});
var form = req.form();
form.append('file', toBuffer(file.data), {
filename: file.name,
contentType: file.type
});
I thought I just saw this question.
In short, no, there's no variable interpolation within an application configuration.
You have two options
Yes surely you can add one, as already mentioned for initialization of Abstract class variables. BUT if you dont explicitly declare one, it anyways has an implicit constructor for "Constructor Chaining" to work.

SQL Case Sensitive String Compare
These examples may be helpful:
Declare @S1 varchar(20) = 'SQL'
Declare @S2 varchar(20) = 'sql'
if @S1 = @S2 print 'equal!' else print 'NOT equal!' -- equal (default non-case sensitivity for SQL
if cast(@S1 as binary) = cast(Upper(@S2) as binary) print 'equal!' else print 'NOT equal!' -- equal
if cast(@S1 as binary) = cast(@S2 as binary) print 'equal!' else print 'NOT equal!' -- not equal
if @S1 COLLATE Latin1_General_CS_AS = Upper(@S2) COLLATE Latin1_General_CS_AS print 'equal!' else print 'NOT equal!' -- equal
if @S1 COLLATE Latin1_General_CS_AS = @S2 COLLATE Latin1_General_CS_AS print 'equal!' else print 'NOT equal!' -- not equal
The convert is probably more efficient than something like runtime calculation of hashbytes, and I'd expect the collate may be even faster.
I realize this is an older question, but it comes up first in a Google search, and among the excellent answers provided, I didn't see anything fully comprehensive, so I did a little more digging and I ended up writing an enum class that not only allowed me to assign multiple custom values to the enum constants, I even added a method that allows me to assign values to them on the fly during code execution.
This enum class is for a "server" program that I run on a Raspberry Pi. The program receives commands from a client then it executes terminal commands that make adjustments to a webcam that is affixed to my 3D printer.
Using the Linux program 'v4l2-ctl' on the Pi, you can extract all of the possible adjustment commands for a given attached webcam, which also provides the setting datatype, the min and max values, the number of value steps in a given value range etc., so I took all of those and put them in an enum and created an enum interface that makes it easy to both set and get values for each command as well as a simple method to get the actual terminal command that is executed (using the Process and Runtime classes) in order to adjust the setting.
It is a rather large class and I apologize for that, but for me, it's always easier to learn something when I can see it working in full context, so I decided not to scale it down. However, even though it's large, it is definitely simple and it should be obvious what's happening in the class with minimal effort.

This code:

PICam.setValue(0,127); //Set brightness to 125
PICam.setValue(PICam.SHARPNESS,143); //Set sharpness to 125
String command1 = PICam.getSetCommandStringFor(PICam.BRIGHTNESS); //Get command line string to include the brightness value that we previously set referencing it by enum constant.
String command2 = PICam.getSetCommandStringFor(0); //Get command line string to include the brightness value that we previously set referencing it by index number.
String command3 = PICam.getDefaultCamString(PICam.BRIGHTNESS); //Get command line string with the default value
String command4 = PICam.getSetCommandStringFor(PICam.SHARPNESS); //Get command line string with the sharpness value that we previously set.
String command5 = PICam.getDefaultCamString(PICam.SHARPNESS); //Get command line string with the default sharpness value.
System.out.println(command1);
System.out.println(command2);
System.out.println(command3);
System.out.println(command4);
System.out.println(command5);
}
Produces these results:
/usr/bin/v4l2-ctl -d /dev/video0 --set-ctrl=brightness=127
/usr/bin/v4l2-ctl -d /dev/video0 --set-ctrl=brightness=127

I wrap everything in one class. Just call these lines of code when your viewcontroller is loaded:
- (void)viewDidLoad {
[super viewDidLoad];
KeyboardInsetScrollView *injectView = [[KeyboardInsetScrollView alloc] init];
[injectView injectToView:self.view withRootView:self.view];
}
Here is link of sample project:
https://github.com/caohuuloc/KeyboardInsetScrollView
The root cause of IllegalStateException exception is a java servlet is attempting to write to the output stream (response) after the response has been committed.
It is always better to ensure that no content is added to the response after the forward or redirect is done to avoid IllegalStateException. It can be done by including a ‘return’ statement immediately next to the forward or redirect statement.
The method show()
must be called from the User-Interface (UI) thread, while doInBackground()
runs on different thread which is the main reason why AsyncTask
was designed.
You have to call show()
either in onProgressUpdate()
or in onPostExecute()
.
For example:
class ExampleTask extends AsyncTask<String, String, String> {
// Your onPreExecute method.
@Override
protected String doInBackground(String... params) {
// Your code.
if (condition_is_true) {
this.publishProgress("Show the dialog");
}
return "Result";
}
@Override
protected void onProgressUpdate(String... values) {
super.onProgressUpdate(values);
connectionProgressDialog.dismiss();
downloadSpinnerProgressDialog.show();
}
}
In HTML5, there is no correct value, all the major browsers do not really care what the attribute is, they are just checking if the attribute exists so the element is disabled.
The Visual Studio Development Server option applies only when you are running (testing) the Web project in Visual Studio. Production Web applications always run under IIS.
To specify the Web server for a Web site project
- In Solution Explorer, right-click the name of the Web site project for which you want to specify a Web server, and then click Property Pages.
- In the Property Pages dialog box, click the Start Options tab.
- Under Server, click Use custom server.
- In the Base URL box, type the URL that Visual Studio should start when running the current project.
Note: If you specify the URL of a remote server (for example, an IIS Web application on another computer), be sure that the remote server is running at least the .NET Framework version 2.0.
To specify the Web server for a Web application project
- In Solution Explorer, right-click the name of the Web application project for which you want to specify a Web server, and then click Properties.
- In the Properties window, click the Web tab.
- Under Servers, click Use Visual Studio Development Server or Use Local IIS Web server or Use Custom Web server.
- If you clicked Local IIS Web server or Use Custom Web Server, in the Base URL box, type the URL that Visual Studio should start when running the current project.
Note: If you clicked Use Custom Web Server and specify the URL of a remote server (for example, an IIS Web application on another computer), be sure that the remote server is running at least the .NET Framework version 2.0.

pthread.h
isn't on Windows. But Windows has extensive threading functionality, beginning with CreateThread.
My advice is don't get caught looking at WinAPI through the lens of another system's API. These systems are different. It's like insisting on riding the Win32 bike with your comfortable Linux bike seat. Well, the seat might not fit right and in some cases it'll just fall off.
Threads pretty much work the same on different systems, you have ThreadPools and mutexes. Having worked with both pthreads
and Windows threads, I can say the Windows threading offers quite a bit more functionality than pthread
does.
Learning another API is pretty easy, just think in terms of the concepts (mutex, etc), then look up how to create one of those on MSDN.
The statement about CMake being a "build generator" is a common misconception.
It's not technically wrong; it just describes HOW it works, but not WHAT it does.
In the context of the question, they do the same thing: take a bunch of C/C++ files and turn them into a binary.
So, what is the real difference?
CMake is much more high-level. It's tailored to compile C++, for which you write much less build code, but can be also used for general purpose build. make
has some built-in C/C++ rules as well, but they are useless at best.
CMake
does a two-step build: it generates a low-level build script in ninja
or make
or many other generators, and then you run it. All the shell script pieces that are normally piled into Makefile
are only executed at the generation stage. Thus, CMake
build can be orders of magnitude faster.
The grammar of CMake
is much easier to support for external tools than make's.
Once make
builds an artifact, it forgets how it was built. What sources it was built from, what compiler flags? CMake
tracks it, make
leaves it up to you. If one of library sources was removed since the previous version of Makefile
, make
won't rebuild it.
Modern CMake
(starting with version 3.something) works in terms of dependencies between "targets". A target is still a single output file, but it can have transitive ("public"/"interface" in CMake terms) dependencies.
These transitive dependencies can be exposed to or hidden from the dependent packages. CMake
will manage directories for you. With make
, you're stuck on a file-by-file and manage-directories-by-hand level.
You could code up something in make
using intermediate files to cover the last two gaps, but you're on your own. make
does contain a Turing complete language (even two, sometimes three counting Guile); the first two are horrible and the Guile is practically never used.
To be honest, this is what CMake
and make
have in common -- their languages are pretty horrible. Here's what comes to mind:
CMake
has three data types: string, list, and a target with properties. make
has one: string;set_property(TARGET helloworld APPEND PROPERTY INCLUDE_DIRECTORIES "${CMAKE_CURRENT_SOURCE_DIR}")
;1- You are using android.graphics.Bitmap which doesn't implements Serializable class so you have to remove that class then it will work.
2- for brief you can visit how to pass data between intents.
You could use numpy.arange
.
EDIT: The docs prefer numpy.linspace
. Thanks @Droogans for noticing =)
Model.find
1- Parameter: ID of the object to find.
2- If found: It returns the object (One object only).
3- If not found: raises an ActiveRecord::RecordNotFound
exception.
Model.find_by
1- Parameter: key/value
Example:
User.find_by name: 'John', email: '[email protected]'
2- If found: It returns the object.
3- If not found: returns nil
.
Note: If you want it to raise ActiveRecord::RecordNotFound
use find_by!
Model.where
1- Parameter: same as find_by
2- If found: It returns ActiveRecord::Relation
containing one or more records matching the parameters.
3- If not found: It return an Empty ActiveRecord::Relation
.
Because that gtab82 table isn't in your FROM or JOIN clause. You refer gtab82 table in these cases: gtab82.memno and gtab82.memacid
Principled Design of the Modern Web Architecture by Roy T. Fielding and Richard N. Taylor, i.e. sequence of works from all REST terminology came from, contains definition of client-server interaction:
All REST interactions are stateless. That is, each request contains all of the information necessary for a connector to understand the request, independent of any requests that may have preceded it.
This restriction accomplishes four functions, 1st and 3rd are important in this particular case:
And now lets go back to your security case. Every single request should contains all required information, and authorization/authentication is not an exception. How to achieve this? Literally send all required information over wires with every request.
One of examples how to archeive this is hash-based message authentication code or HMAC. In practice this means adding a hash code of current message to every request. Hash code calculated by cryptographic hash function in combination with a secret cryptographic key. Cryptographic hash function is either predefined or part of code-on-demand REST conception (for example JavaScript). Secret cryptographic key should be provided by server to client as resource, and client uses it to calculate hash code for every request.
There are a lot of examples of HMAC implementations, but I'd like you to pay attention to the following three:
If client knows the secret key, then it's ready to operate with resources. Otherwise he will be temporarily redirected (status code 307 Temporary Redirect) to authorize and to get secret key, and then redirected back to the original resource. In this case there is no need to know beforehand (i.e. hardcode somewhere) what the URL to authorize the client is, and it possible to adjust this schema with time.
Hope this will helps you to find the proper solution!
just wanted to put my 2cents in about this issue...
I had a similar need where i was pulling data from another table via INDEX/MATCH, and it was difficult to distinguish between a real 0 value vs. a 0 value because of no match (for example for a column chart that shows the progress of values over the 12 months and where we are only in february but the rest of the months data is not available yet and the column chart still showed 0's everywhere for Mar to Dec)
What i ended up doing is create a new series and plot this new series on the graph as a line chart and then i hid the line chart by choosing not to display the line in the options and i put the data labels on top, the formula for the values for this new series was something like :
=IF(LEN([@[column1]])=0,NA(),[@[column1]])
I used LEN as a validation because ISEMPTY/ISBLANK didn't work because the result of the INDEX/MATCH always returned something other than a blank even though i had put a "" after the IFERROR...
On the line chart the error value NA() makes it so that the value isn't displayed ...so this worked out for me...
I guess it's a bit difficult to follow this procedure without pictures, but i hope it paints some kind of picture to allow you to use a workaround if you have a similar case like mine
Here is the simplest example that has the key lines of code:
import numpy as np
import matplotlib.pyplot as plt
H = np.array([[1, 2, 3, 4],
[5, 6, 7, 8],
[9, 10, 11, 12],
[13, 14, 15, 16]])
plt.imshow(H, interpolation='none')
plt.show()
Possibly too late to be of benefit now, but is this not the easiest way to do things?
SELECT empName, projIDs = replace

Print the PDF header (using header() function) like:
header("Content-type: application/pdf");
and then just echo the content of the PDF file you created (instead of writing it to disk).
If using Visual Studio 2010 you can right-click on the project for the service, and select properties
. Then select the Web
tab. Under the Servers
section you can configure the URL. There is also a button to create the virtual directory.
This is known as a Shebang
:
http://en.wikipedia.org/wiki/Shebang_(Unix)
#!interpreter [optional-arg]
A shebang is only relevant when a script has the execute permission (e.g. chmod u+x script.sh).
When a shell executes the script it will use the specified interpreter.
Example:
#!/bin/bash
# file: foo.sh
echo 1
$ chmod u+x foo.sh
$ ./foo.sh

From the Google Font Directory examples:
@font-face {
font-family: 'Tangerine';
font-style: normal;
font-weight: normal;
src: local('Tangerine'), url('http://example.com/tangerine.ttf') format('truetype');
}
body {
font-family: 'Tangerine', serif;
font-size: 48px;
}
This works cross browser with .ttf, I believe it may work with .otf. (Wikipedia says .otf is mostly backwards compatible with .ttf) If not, you can convert the .otf to .ttf
Here are some good sites:
Good primer:
Other Info:
I think you would be look at String class, there are multiple ways to do it. What about substring(int,int)
and indexOf(int)
lastIndexOf(int)
?
With Mac OS X and the more recent versions of Acrobat Pro, the PDF printer option does not work. What does work is doing basically the same thing in Preview App. Open the multi page file in Preview, select File>Print. In the Print dialog set your sheet size as if you are using a printer. You may want to select "Auto Rotate", "Scale to Fit" and "Print Entire Image". Then in the lower left corner is the drop button "PDF" and in that menu select "Save as PDF". Give it a new file name, click Save and then you can open the resulting file in whatever PDF app you want and the sheet sizes are the same.
You could use an extension for Chrome, that works well the times I have tried it.
https://chrome.google.com/webstore/search/html%20table%20to%20csv?_category=extensions
When installed and on any web page with a table if you click on this extension's icon it shows all the tables in the page, highlighting each as you roll over the tables it lists, clicking allows you to copy it to the clipboard or save it to a Google Doc.
It works perfectly for what I need, which is occasional conversion of web based tabular data into a spreadsheet I can work with.
Simply write to file string.Empty
, when append is set to false in StreamWriter. I think this one is easiest to understand for beginner.
private void ClearFile()
{
if (!File.Exists("TextFile.txt"))
File.Create("TextFile.txt");
TextWriter tw = new StreamWriter("TextFile.txt", false);
tw.Write(string.Empty);
tw.Close();
}
You need to declare out
as a byte array with a length equal to the lengths of ciphertext
and mac
added together, and then copy ciphertext
over the beginning of out
and mac
over the end, using arraycopy.
byte[] concatenateByteArrays(byte[] a, byte[] b) {
byte[] result = new byte[a.length + b.length];
System.arraycopy(a, 0, result, 0, a.length);
System.arraycopy(b, 0, result, a.length, b.length);
return result;
}
Because strip()
only strips trailing and leading characters, based on what you provided. I suggest:
>>> import re
>>> name = "Barack (of Washington)"
>>> name = re.sub('[\(\)\{\}<>]', '', name)
>>> print(name)
Barack of Washington
After looking through all the different methods posted here, I didn't see anyone utilize TRUE/FALSE
to select and unselect data. So I thought I would share a method utilizing that technique.
n = nrow(dataset)
split = sample(c(TRUE, FALSE), n, replace=TRUE, prob=c(0.75, 0.25))
training = dataset[split, ]
testing = dataset[!split, ]
There are multiple ways of selecting data from R, most commonly people use positive/negative indices to select/unselect respectively. However, the same functionalities can be achieved by using TRUE/FALSE
to select/unselect.
Consider the following example.
# let's explore ways to select every other element
data = c(1, 2, 3, 4, 5)
# using positive indices to select wanted elements
data[c(1, 3, 5)]
[1] 1 3 5
# using negative indices to remove unwanted elements
data[c(-2, -4)]
[1] 1 3 5
# using booleans to select wanted elements
data[c(TRUE, FALSE, TRUE, FALSE, TRUE)]
[1] 1 3 5
# R recycles the TRUE/FALSE vector if it is not the correct dimension
data[c(TRUE, FALSE)]
[1] 1 3 5
I believe that the problem in the fact that Moq will check for equality. And, since XmlElement does not override Equals, it's implementation will check for reference equality.
Can't you use a custom object, so you can override equals?
<?php
$var1 = "Line 1 info blah blah <br /> Line 2 info blah blah";
$var1 = str_replace("<br />", "\n", $var1);
?>
<textarea><?php echo $var1; ?></textarea>
First of all you will need to define, which data type you need to keep in your list. As you have mentioned that the data is going to be String, the list should be made of type String.
Then if you want to get all the elements of the list, you have to just iterate over the list using a simple for loop or a for each loop.
List <String> list = new ArrayList<>();
list.add("A");
list.add("B");
for(String s : list){
System.out.println(s);
}
Also, if you want to use a raw ArrayList instead of a generic one, you will have to downcast the value. When using the raw ArrayList, all the elements are stored in form of Object.
List list = new ArrayList();
list.add("A");
list.add("B");
for(Object obj : list){
String s = (String) obj; //downcasting Object to String
System.out.println(s);
}
If the value stored in PropertyLoader.RET_SECONDARY_V_ARRAY
is not "V_ARRAY"
, then you are using different types; even if they are declared identically (e.g. both are table of number
) this will not work.
You're hitting this data type compatibility restriction:
You can assign a collection to a collection variable only if they have the same data type. Having the same element type is not enough.
You're trying to call the procedure with a parameter that is a different type to the one it's expecting, which is what the error message is telling you.
Add !important
rule to display: table

int[][] myNums = { {1, 2, 3, 4, 5, 6, 7}, {5, 6, 7, 8, 9, 10, 11} };
for (int x = 0; x < myNums.length; ++x) {
for(int y = 0; y < myNums[i].length; ++y) {
System.out.print(myNums[x][y]);
}
}
Output
1 2 3 4 5 6 7 5 6 7 8 9 10 11
If you have the product's ID you can use that to create a product object:
$_product = wc_get_product( $product_id );
Then from the object you can run any of WooCommerce's product methods.
$_product->get_regular_price();
$_product->get_sale_price();
$_product->get_price();
Update
Please review the Codex article on how to write your own shortcode.
Integrating the WooCommerce product data might look something like this:
function so_30165014_price_shortcode_callback( $atts ) {
$atts = shortcode_atts( array(
'id' => null,
), $atts, 'bartag' );
$html = '';
if( intval( $atts['id'] ) > 0 && function_exists( 'wc_get_product' ) ){
$_product = wc_get_product( $atts['id'] );
$html = "price = " . $_product->get_price();
}
return $html;
}
add_shortcode( 'woocommerce_price', 'so_30165014_price_shortcode_callback' );
Your shortcode would then look like [woocommerce_price id="99"]
In may case, I'd simply used
vagrant up
instead of
homestead up
for my forge larval setup using homestead. I'm assuming this meant the site was getting served, but the MySQL server wasn't ever booted. When I used the latter command to launch my vagrant box, the error went away.
if you set style="height:100px;" on a td if the td has content that grows the cell more than that, it will do so no need for min height on a td.
Make sure that the attribute is primary key and Auto Incrementable in the database. Then map it into the data class with the annotation with @GeneratedValue
annotation using IDENTITY.

@Table(name = "client")
data class Client(

From the Android Developers page,
onPause():
Called when the system is about to start resuming a previous activity. This is typically used to commit unsaved changes to persistent data, stop animations and other things that may be consuming CPU, etc. Implementations of this method must be very quick because the next activity will not be resumed until this method returns. Followed by either onResume() if the activity returns back to the front, or onStop() if it becomes invisible to the user.
onStop():
Called when the activity is no longer visible to the user, because another activity has been resumed and is covering this one. This may happen either because a new activity is being started, an existing one is being brought in front of this one, or this one is being destroyed. Followed by either onRestart() if this activity is coming back to interact with the user, or onDestroy() if this activity is going away.
Now suppose there are three Activities and you go from A to B, then onPause of A will be called now from B to C, then onPause of B and onStop of A will be called.
The paused Activity gets a Resume and Stopped gets Restarted.
When you call this.finish()
, onPause-onStop-onDestroy will be called. The main thing to remember is: paused Activities get Stopped and a Stopped activity gets Destroyed whenever Android requires memory for other operations.
I hope it's clear enough.
I would use bash's [[
:
if [[ ! ("$#" == 1 && $1 =~ ^[0-9]+$ && -d $1) ]]; then
echo 'Please pass a number that corresponds to a directory'
exit 1
fi
I found this faq to be a good source of information.
The best solution, works in all browsers.. even on mobile.
<div class="btn" id="s_photo">Upload</div>
<input type="file" name="s_file" id="s_file" style="opacity: 0;">';
<!--jquery-->
<script>
$("#s_photo").click(function() {
$("#s_file").trigger("click");
});
</script>
Hiding the input file type causes problems with browsers, opacity is the best solution because it isn't hiding, just not showing. :)

Create a base class for your ViewModels
with the following constructor code which will apply the DefaultValueAttributes
when any inheriting model is created.
public abstract class BaseViewModel
{
protected BaseViewModel()
{
// apply any DefaultValueAttribute settings to their properties
var propertyInfos = this.GetType().GetProperties();
foreach (var propertyInfo in propertyInfos)
{
var attributes = propertyInfo.GetCustomAttributes(typeof(DefaultValueAttribute), true);
if (attributes.Any())
{
var attribute = (DefaultValueAttribute) attributes[0];
propertyInfo.SetValue(this, attribute.Value, null);
}
}
}
}
And inherit from this in your ViewModels:
public class SearchModel : BaseViewModel
{
[DefaultValue(true)]
public bool IsMale { get; set; }
[DefaultValue(true)]
public bool IsFemale { get; set; }
}
I use combination of several plugins - for the basic assignment of roles and permission I use Role Strategy Plugin.
When I need to split some role depending on parameters (e.g. everybody with job-runner is able to run jobs, but user only user UUU is allowed to run the deployment job to deploy on machine MMM), I use Python Plugin and define a python script as first build step and end with sys.exit(-1) when the job is forbidden to be run with the given combination of parameters.
Build User Vars Plugin provides me the information about the user executing the job as environment variables.
E.g:
import os
import sys
print os.environ["BUILD_USER"], "deploying to", os.environ["target_host"]
# only some users are allowed to deploy to servers "MMM"
mmm_users = ["UUU"]
if os.environ["target_host"] != "MMM" or os.environ["BUILD_USER"] in mmm_users:
print "access granted"
else:
print "access denied"
sys.exit(-1)
I just encountered a case of needing to revert just one file to previous revision, right after I had done commit and push. Shorthand syntax for specifying these revisions isn't covered by the other answers, so here's command to do that
hg revert path/to/file -r-2
That -2
will revert to the version before last commit, using -1
would just revert current uncommitted changes.
I know this is old, but also make sure that none of your docker containers are already on port 80. That was my issue.
You can use assertException extension to assert more than one exception during one test execution.
Insert method into your TestCase and use:
public function testSomething()
{
$test = function() {
// some code that has to throw an exception
};
$this->assertException( $test, 'InvalidArgumentException', 100, 'expected message' );
}
I also made a trait for lovers of nice code..
AND
and OR
are just syntactic sugar for &&
and ||
, like in JavaScript, or other C styled syntax languages.
It appears AND
and OR
have lower precedence than their C style equivalents.
$total_ratings
is an array.
try
{
..
..
..
}
catch(Exception ex)
{
..
..
..
}
the Exception ex means all the exceptions.
When you do not want to have the emails in the list that are in the database you'll can do the following:
select u.name
, u.EMAIL
, a.emailadres
, case when a.emailadres is null then 'Not exists'
else 'Exists'
end as 'Existence'
from users u
left join ( select 'email1' as emailadres
union all select 'email2'
union all select 'email3') a
on a.emailadres = u.EMAIL)
this way you'll get a result like
name | email | emailadres | existence
-----|--------|------------|----------
NULL | NULL | [email protected] | Not exists
Jan | [email protected] | [email protected] | Exists
Using the IN or EXISTS operators are more heavy then the left join in this case.
Good luck :)
I found out why this happening.
After looking at my settings on my wamp, i did not check http headers, since activated this, it now works.
Thank you everyone for trying to solve this. :)

In case any one stumbles upon this as I just have...
Find First blank cell in a column(I'm using column D but didn't want to include D1)
NextFree = Range("D2:D" & Rows.Count).Cells.SpecialCells(xlCellTypeBlanks).Row
Range("D" & NextFree).Select
NextFree is just a name, you could use sausages if you wanted.
You can use GNU Trove library:
TIntList tt = new TIntArrayList();
tt.add(1);
tt.add(2);
tt.add(3);
int sum = tt.sum();
You can use this way because id can not be sequential in all cases.

In case the OP really wanted an ICMP-Ping, there are some proposals within the User Contributed Notes to socket_create()
[link], which use raw sockets. Be aware that on UNIX like systems root access is required.
Update: note that the usec
argument has no function on windows. Minimum timeout is 1 second.
In any case, this is the code of the top voted ping function:
function ping($host, $timeout = 1) {
/* ICMP ping packet with a pre-calculated checksum */
$package = "\x08\x00\x7d\x4b\x00\x00\x00\x00PingHost";
$socket = socket_create(AF_INET, SOCK_RAW, 1);
socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO, array('sec' => $timeout, 'usec' => 0));
socket_connect($socket, $host, null);
$ts = microtime(true);
socket_send($socket, $package, strLen($package), 0);
if (socket_read($socket, 255)) {
$result = microtime(true) - $ts;
} else {
$result = false;
}
socket_close($socket);
return $result;
}
The PermGen space is what Tomcat uses to store class definitions (definitions only, no instantiations) and string pools that have been interned. From experience, the PermGen space issues tend to happen frequently in dev environments really since Tomcat has to load new classes every time it deploys a WAR or does a jspc (when you edit a jsp file). Personally, I tend to deploy and redeploy wars a lot when I’m in dev testing so I know I’m bound to run out sooner or later (primarily because Java’s GC cycles are still kinda crap so if you redeploy your wars quickly and frequently enough, the space fills up faster than they can manage).
This should theoretically be less of an issue in production environments since you (hopefully) don’t change the codebase on a 10 minute basis. If it still occurs, that just means your codebase (and corresponding library dependencies) are too large for the default memory allocation and you’ll just need to mess around with stack and heap allocation. I think the standards are stuff like:
-XX:MaxPermSize=SIZE
I’ve found however the best way to take care of that for good is to allow classes to be unloaded so your PermGen never runs out:
-XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled
Stuff like that worked magic for me in the past. One thing tho, there’s a significant performance tradeoff in using those, since permgen sweeps will make like an extra 2 requests for every request you make or something along those lines. You’ll need to balance your use with the tradeoffs.
This is not possible. If you want to display text inside a rect element you should put them both in a group with the text element coming after the rect element ( so it appears on top ).
<svg xmlns="http://www.w3.org/2000/svg">_x000D_
<g>_x000D_
<rect x="0" y="0" width="100" height="100" fill="red"></rect>_x000D_

To get the values use
sorted(data.values())
To get the matching keys, use a key
function
sorted(data, key=data.get)
To get a list of tuples ordered by value
sorted(data.items(), key=lambda x:x[1])
Related: see the discussion here: Dictionaries are ordered in Python 3.6+
I'd like to add that for accessibility, I think you should add focus trigger :
i.e. $("#popover").popover({ trigger: "hover focus" });
Date to Locale date string:
Date date = new Date();
String stringDate = DateFormat.getDateTimeInstance().format(date);
Options:
DateFormat.getDateInstance()
- > Dec 31, 1969
DateFormat.getDateTimeInstance()
-> Dec 31, 1969 4:00:00 PM
DateFormat.getTimeInstance()
-> 4:00:00 PM
For what it's worth I do miss the ^ operator when raising a power of 2 to define a binary constant. Can't use Math.Pow() there, but shifting an unsigned int of 1 to the left by the exponent's value works. When I needed to define a constant of (2^24)-1:
public static int Phase_count = 24;
public static uint PatternDecimal_Max = ((uint)1 << Phase_count) - 1;
Remember the types must be (uint) << (int).
Django 2.2 version now has a bulk_update
method (release notes).
https://docs.djangoproject.com/en/stable/ref/models/querysets/#bulk-update
Example:
# get a pk: record dictionary of existing records
updates = YourModel.objects.filter(...).in_bulk()
....
# do something with the updates dict
....
if hasattr(YourModel.objects, 'bulk_update') and updates:
# Use the new method
YourModel.objects.bulk_update(updates.values(), [list the fields to update], batch_size=100)
else:
# The old & slow way
with transaction.atomic():
for obj in updates.values():
obj.save(update_fields=[list the fields to update])
Edit: The original is below. When one Android Studio didn't exist. But if you want to filter on your entire application I would use pidcat for terminal viewing or Android Studio. Using pidcat instead of logcat then the tags don't need to be the application. You can just call it with pidcat com.your.application
You should use your own tag, look at: http://developer.android.com/reference/android/util/Log.html
Like.
Log.d("AlexeysActivity","what you want to log");
And then when you want to read the log use>
adb logcat -s AlexeysActivity
That filters out everything that doesn't use the same tag.
You can test using eval
:
try:
eval("1 if True else 2")
except SyntaxError:
# doesn't have ternary
Also, with
is available in Python 2.5, just add from __future__ import with_statement
.
EDIT: to get control early enough, you could split it into different .py
files and check compatibility in the main file before importing (e.g. in __init__.py
in a package):
# __init__.py
# Check compatibility
try:
eval("1 if True else 2")
except SyntaxError:
raise ImportError("requires ternary support")
# import from another module
from impl import *
I couldn't respond to Mark above, but I just made one modification which fixed the error which was caused if data in the cells was not unicode, i.e. float or int data. I replaced this line into the UnicodeWriter function: "self.writer.writerow([s.encode("utf-8") if type(s)==types.UnicodeType else s for s in row])" so that it became:
class UnicodeWriter:
def __init__(self, f, dialect=csv.excel, encoding="utf-8-sig", **kwds):
self.queue = cStringIO.StringIO()
self.writer = csv.writer(self.queue, dialect=dialect, **kwds)
self.stream = f
self.encoder = codecs.getincrementalencoder(encoding)()
def writerow(self, row):
'''writerow(unicode) -> None
This function takes a Unicode string and encodes it to the output.
'''
self.writer.writerow([s.encode("utf-8") if type(s)==types.UnicodeType else s for s in row])
data = self.queue.getvalue()
data = data.decode("utf-8")
data = self.encoder.encode(data)
self.stream.write(data)
self.queue.truncate(0)
def writerows(self, rows):
for row in rows:
self.writerow(row)
You will also need to "import types".
You probably want to use an ExpandableListView, a special ListView that allows you to open and close groups.
In the current version of Sublime Text 2 (Build: 2139), you can set the syntax for all files of a certain file extension using an option in the menu bar. Open a file with the extension you want to set a default for and navigate through the following menus: View -> Syntax -> Open all with current extension as... ->[your syntax choice]
.
Updated 2012-06-28: Recent builds of Sublime Text 2 (at least since Build 2181) have allowed the syntax to be set by clicking the current syntax type in the lower right corner of the window. This will open the syntax selection menu with the option to Open all with current extension as...
at the top of the menu.
Updated 2016-04-19: As of now, this also works for Sublime Text 3.
Use system("cls")
to clear the screen:
#include <stdlib.h>

}
By using Constructor Injection, you assert the requirement for the dependency in a container-agnostic manner
We need the assurance from the IoC container that, before using any bean, the injection of necessary beans must be done.
In setter injection strategy, we trust the IoC container that it will first create the bean first but will do the injection right before using the bean using the setter methods. And the injection is done according to your configuration. If you somehow misses to specify any beans to inject in the configuration, the injection will not be done for those beans and your dependent bean will not function accordingly when it will be in use!
But in constructor injection strategy, container imposes (or must impose) to provide the dependencies properly while constructing the bean. This was addressed as " container-agnostic manner", as we are required to provide dependencies while creating the bean, thus making the visibility of dependency, independent of any IoC container.
Edit:
Q1: And how to prevent container from creating bean by constructor with null
values instead of missing beans?
You have no option to really miss any <constructor-arg>
(in case of Spring), because you are imposed by IoC container to provide all the constructor arguments needed to match a provided constructor for creating the bean. If you provide null
in your <constructor-arg>
intentionally. Then there is nothing IoC container can do or need to do with it!
Orabig is correct.
You can bind 10.0.2.15 in Ubuntu (VirtualBox) then do a port forwarding from host to guest Ubuntu.
in /etc/redis/redis.conf
bind 10.0.2.15
then, restart redis:
sudo systemctl restart redis
It shall work!
You only need a single line of code to set the border around every cell in the range:
Range("A1:F20").Borders.LineStyle = xlContinuous
It's also easy to apply multiple effects to the border around each cell.
For example:
Sub RedOutlineCells()
Dim rng As Range
Set rng = Range("A1:F20")
With rng.Borders
.LineStyle = xlContinuous
.Color = vbRed
.Weight = xlThin
End With
End Sub
If min value in array, you can try like:
>>> mydict = {"a": -1.5, "b": -1000.44, "c": -3}
>>> min(mydict.values())
-1000.44
I think, the easiest way is to read readme file inside your Eclipse directory at path eclipse/readme/eclipse_readme
.
At the very top of this file it clearly tells the version number:
For My Eclipse Juno; it says version as Release 4.2.0
Your sleep
function does not work because setTimeout
does not (yet?) return a promise that could be await
ed. You will need to promisify it manually:
function timeout(ms) {
return new Promise(resolve => setTimeout(resolve, ms));
}
async function sleep(fn, ...args) {
await timeout(3000);
return fn(...args);
}
Btw, to slow down your loop you probably don't want to use a sleep
function that takes a callback and defers it like this. I recommend:
while (goOn) {
// other code
var [parents] = await Promise.all([
listFiles(nextPageToken).then(requestParents),
timeout(5000)
]);
// other code
}
which lets the computation of parents
take at least 5 seconds.
In iOS7, if your navigation controller is contained in tab bar, splitview or some other container, then for globally changing navigationbar appearance use following method ::
[[UINavigationBar appearanceWhenContainedIn:[UITabBarController class],nil] setBarTintColor:[UIColor blueColor]];
First, I see you're using an explicit $.parseJSON()
. If that's because you're manually serializing JSON on the server-side, don't. ASP.NET will automatically JSON-serialize your method's return value and jQuery will automatically deserialize it for you too.
To iterate through the first item in the array you've got there, use code like this:
var firstItem = response.d[0];
for(key in firstItem) {
console.log(key + ':' + firstItem[key]);
}
If there's more than one item (it's hard to tell from that screenshot), then you can loop over response.d
and then use this code inside that outer loop.
Here the packaging is jar type, hence you need to use manifest plugin, in order to add dependencies into the Manifest.mf
The problem here is that maven could find the dependencies in pom file and compile the source code and create the output jar. But when executing the jar, manifest.mf file contains no details of dependencies. Hence you got this error. This is a case of classpath errors.
Here you can find the details on how to do it.
If I'm correct, you're looking for the socket.gethostname function:
>> import socket
>> socket.gethostname()
'terminus'
While binding a databound control, you can evaluate a field of the row in your data source with eval() function.
For example you can add a column to your gridview like that :
<asp:BoundField DataField="YourFieldName" />
And alternatively, this is the way with eval :
<asp:TemplateField>
<ItemTemplate>
<asp:Label ID="lbl" runat="server" Text='<%# Eval("YourFieldName") %>'>
</asp:Label>
</ItemTemplate>
</asp:TemplateField>
It seems a little bit complex, but it's flexible, because you can set any property of the control with the eval() function :
<asp:TemplateField>
<ItemTemplate>
<asp:HyperLink ID="HyperLink1" runat="server"
NavigateUrl='<%# "ShowDetails.aspx?id="+Eval("Id") %>'
Text='<%# Eval("Text", "{0}") %>'></asp:HyperLink>
</ItemTemplate>
</asp:TemplateField>

If you have the name of the remote, you will be able with git 2.7 (Q4 2015), to use the new git remote get-url
command:
git remote get-url origin
(nice pendant of git remote set-url origin <newurl>
)
See commit 96f78d3 (16 Sep 2015) by Ben Boeckel (mathstuf
).
(Merged by Junio C Hamano -- gitster
-- in commit e437cbd, 05 Oct 2015)
remote: add get-url subcommand
Expanding
insteadOf
is a part ofls-remote --url
and there is no way to expandpushInsteadOf
as well.
Add aget-url
subcommand to be able to query both as well as a way to get all configured urls.
While the rules in C++03 about when you need typename
and template
are largely reasonable, there is one annoying disadvantage of its formulation
template<typename T>
struct A {
typedef int result_type;
void f() {
// error, "this" is dependent, "template" keyword needed
this->g<float>();
// OK
g<float>();
// error, "A<T>" is dependent, "typename" keyword needed
A<T>::result_type n1;
// OK
result_type n2;
}
template<typename U>
void g();
};
As can be seen, we need the disambiguation keyword even if the compiler could perfectly figure out itself that A::result_type
can only be int
(and is hence a type), and this->g
can only be the member template g
declared later (even if A
is explicitly specialized somewhere, that would not affect the code within that template, so its meaning cannot be affected by a later specialization of A
!).
To improve the situation, in C++11 the language tracks when a type refers to the enclosing template. To know that, the type must have been formed by using a certain form of name, which is its own name (in the above, A
, A<T>
, ::A<T>
). A type referenced by such a name is known to be the current instantiation. There may be multiple types that are all the current instantiation if the type from which the name is formed is a member/nested class (then, A::NestedClass
and A
are both current instantiations).
Based on this notion, the language says that CurrentInstantiation::Foo
, Foo
and CurrentInstantiationTyped->Foo
(such as A *a = this; a->Foo
) are all member of the current instantiation if they are found to be members of a class that is the current instantiation or one of its non-dependent base classes (by just doing the name lookup immediately).
The keywords typename
and template
are now not required anymore if the qualifier is a member of the current instantiation. A keypoint here to remember is that A<T>
is still a type-dependent name (after all T
is also type dependent). But A<T>::result_type
is known to be a type - the compiler will "magically" look into this kind of dependent types to figure this out.
struct B {
typedef int result_type;
};
template<typename T>
struct C { }; // could be specialized!
template<typename T>
struct D : B, C<T> {
void f() {
// OK, member of current instantiation!
// A::result_type is not dependent: int
D::result_type r1;
// error, not a member of the current instantiation
D::questionable_type r2;
// OK for now - relying on C<T> to provide it
// But not a member of the current instantiation
typename D::questionable_type r3;
}
};
That's impressive, but can we do better? The language even goes further and requires that an implementation again looks up D::result_type
when instantiating D::f
(even if it found its meaning already at definition time). When now the lookup result differs or results in ambiguity, the program is ill-formed and a diagnostic must be given. Imagine what happens if we defined C
like this
template<>
struct C<int> {
typedef bool result_type;
typedef int questionable_type;
};
A compiler is required to catch the error when instantiating D<int>::f
. So you get the best of the two worlds: "Delayed" lookup protecting you if you could get in trouble with dependent base classes, and also "Immediate" lookup that frees you from typename
and template
.
In the code of D
, the name typename D::questionable_type
is not a member of the current instantiation. Instead the language marks it as a member of an unknown specialization. In particular, this is always the case when you are doing DependentTypeName::Foo
or DependentTypedName->Foo
and either the dependent type is not the current instantiation (in which case the compiler can give up and say "we will look later what Foo
is) or it is the current instantiation and the name was not found in it or its non-dependent base classes and there are also dependent base classes.
Imagine what happens if we had a member function h
within the above defined A
class template
void h() {
typename A<T>::questionable_type x;
}
In C++03, the language allowed to catch this error because there could never be a valid way to instantiate A<T>::h
(whatever argument you give to T
). In C++11, the language now has a further check to give more reason for compilers to implement this rule. Since A
has no dependent base classes, and A
declares no member questionable_type
, the name A<T>::questionable_type
is neither a member of the current instantiation nor a member of an unknown specialization. In that case, there should be no way that that code could validly compile at instantiation time, so the language forbids a name where the qualifier is the current instantiation to be neither a member of an unknown specialization nor a member of the current instantiation (however, this violation is still not required to be diagnosed).
You can try this knowledge on this answer and see whether the above definitions make sense for you on a real-world example (they are repeated slightly less detailed in that answer).
The C++11 rules make the following valid C++03 code ill-formed (which was not intended by the C++ committee, but will probably not be fixed)
struct B { void f(); };
struct A : virtual B { void f(); };
template<typename T>
struct C : virtual B, T {
void g() { this->f(); }
};
int main() {
C<A> c; c.g();
}
This valid C++03 code would bind this->f
to A::f
at instantiation time and everything is fine. C++11 however immediately binds it to B::f
and requires a double-check when instantiating, checking whether the lookup still matches. However when instantiating C<A>::g
, the Dominance Rule applies and lookup will find A::f
instead.
To get the equivalent of a static constructor, you need to write a separate ordinary class to hold the static data and then make a static instance of that ordinary class.
class StaticStuff
{
std::vector<char> letters_;
public:
StaticStuff()
{
for (char c = 'a'; c <= 'z'; c++)
letters_.push_back(c);
}
// provide some way to get at letters_
};
class Elsewhere
{
static StaticStuff staticStuff; // constructor runs once, single instance
};
When you have multiple if
conditions, numpy.select
is the way to go:
In [4102]: import numpy as np
In [4098]: conditions = [df.A.eq(df.B), df.A.gt(df.B), df.A.lt(df.B)]
In [4096]: choices = [0, 1, -1]
In [4100]: df['C'] = np.select(conditions, choices)
In [4101]: df
Out[4101]:
A B C
a 2 2 0
b 3 1 1
c 1 3 -1
If you want to do it in one command:
PGPASSWORD="mypass" pg_dump mydb > mydb.dump
Just put
export HOME=/blah/whatever
at the point in the script where you want the change to happen. Since each process has its own set of environment variables, this definition will automatically cease to have any significance when the script terminates (and with it the instance of bash that has a changed environment).

managerId INTEGER REFERENCES employees(id),
name VARCHAR(30) NOT NULL
);
INSERT INTO employees(id, managerId, name) VALUES(1, NULL, 'John');
INSERT INTO employees(id, managerId, name) VALUES(2, 1, 'Mike');
-- Explanation: -- In this example. -- John is Mike's manager. Mike does not manage anyone. -- Mike is the only employee who does not manage anyone.
I had a similar thing to work on, and this is how I did it.
import os
rootdir = os.getcwd()
for subdir, dirs, files in os.walk(rootdir):
for file in files:
#print os.path.join(subdir, file)
filepath = subdir + os.sep + file
if filepath.endswith(".html"):
print (filepath)
Hope this helps.
I had the same error here MacOSX 10.6.8 - it seems ruby checks to see if any directory (including the parents) in the path are world writable. In my case there wasn't a /usr/local/bin present as nothing had created it.
so I had to do
sudo chmod 775 /usr/local
to get rid of the warning.
A question here is does any non root:wheel process in MacOS need to create anything in /usr/local ?
find()
takes a selector, not a value. This means you need to use it in the same way you would use the regular jQuery function ($('selector')
).
Therefore you need to do something like this:
$(this).find('[value="X"]').remove();
See the jQuery find docs.
Try this
<style>
@font-face {
font-family: Roboto Bold Condensed;
src: url(fonts/Roboto_Condensed/RobotoCondensed-Bold.ttf);
}
@font-face {

src: url(fonts/Roboto_Condensed/RobotoCondensed-Regular.tff);
}
div1{
font-family:Roboto Bold Condensed;
}
div2{
font-family:Roboto Condensed;
}
</style>
<div id='div1' >This is Sample text</div>
<div id='div2' >This is Sample text</div>
You can make this method static.
public static void startChronometer(){
mChronometer.start();
showElapsedTime();
}
you can call this function in other class as below:
MainActivity.startChronometer();
OR
You can make an object of the main class in second class like,
MainActivity mActivity = new MainActivity();
mActivity.startChronometer();

org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8
It will work!. Thanks.
There is a crop()
method:
w, h = yourImage.size
yourImage.crop((0, 30, w, h-30)).save(...)
This worked for me, in my case I had a button with a data-id attribute:
$("a").data("item-id");
In my case the error got resolved by migrating to OpenCV 4.0 (or higher).
Most importantly you need to mount the drive
net use z: \\yourserver\sharename
Of course, you need to make sure that the account the batch file runs under has permission to access the share. If you are doing this by using a Scheduled Task, you can choose the account by selecting the task, then:
"When running the task, use the following user account:" That's on Windows 7, it might be slightly different on different versions of Windows.
Then run your batch script with the following changes
copy "z:\FolderName" "C:\TEST_BACKUP_FOLDER"
Found this on github...
import warnings
warnings.simplefilter(action='ignore', category=FutureWarning)
import pandas
In the button's XML set android:includeFontPadding="false"
I'm not really sure, but you can try some like this:
var pack = function( arr ) {
var length = arr.length,
result = {},
i;
for ( i = 0; i < length; i++ ) {
result[ ( i < 10 ? '0' : '' ) + ( i + 1 ) ] = arr[ i ];
}
return result;
};
pack( [ 'one', 'two', 'three' ] ); //{01: "one", 02: "two", 03: "three"}
You can get the total number of rows containing a specific name using:
SELECT COUNT(*) FROM tbl_foo WHERE name = 'sarmen'
Given the count, you can now get the nth row using:
SELECT * FROM tbl_foo WHERE name = 'sarmen' LIMIT (n - 1), 1
Where 1 <= n <= COUNT(*) from the first query.
Example:
getting the 3rd row
SELECT * FROM tbl_foo WHERE name = 'sarmen' LIMIT 2, 1
The accepted OMG Ponies' "Supported by any database" solution has good speed from my test.
Here I provide a same-approach, but more complete and clean any-database solution. Ties are considered (assume desire to get only one row for each customer, even multiple records for max total per customer), and other purchase fields (e.g. purchase_payment_id) will be selected for the real matching rows in the purchase table.
Supported by any database:
select * from purchase
join (
select min(id) as id from purchase
join (
select customer, max(total) as total from purchase
group by customer
) t1 using (customer, total)
group by customer
) t2 using (id)
order by customer
This query is reasonably fast especially when there is a composite index like (customer, total) on the purchase table.
Remark:
t1, t2 are subquery alias which could be removed depending on database.
Caveat: the using (...)
clause is currently not supported in MS-SQL and Oracle db as of this edit on Jan 2017. You have to expand it yourself to e.g. on t2.id = purchase.id
etc. The USING syntax works in SQLite, MySQL and PostgreSQL.
Configuration configManager = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);

Uri is wrong, there is a way to add parameters to main method in Eclipse directly, however the parameters won't be very flexible (some dynamic parameters are allowed). Here's what you need to do:
Run -> Run configurations...
Java Application
or by typing its name to filter box.Program arguments
box. Just in case it isn't clear, they're whitespace-separated so "a b c"
(without quotes) would mean you'd pass arguments a, b and c to your program.I do however recommend using JUnit/wrapper class just like Uri did say since that way you get a lot better control over the actual parameters than by doing this.
I ran into the same issue on windows 7. I managed to get it working by creating a "pip" folder with a "pip.ini" file inside it. I put this folder inside "C:\Users\{my.username}\AppData\Roaming", because according to the Python documentation:
On Windows the configuration file is %APPDATA%\pip\pip.ini
In the pip.ini file I have only:
[global]
proxy = [proxy address]:[proxy port]
So no username:password. And it is working just fine.
Try This
$(this).closest('.ui-dialog-content').dialog('close');
It will close the dialog inside it.
var isOpera = !!window.opera || navigator.userAgent.indexOf('Opera') >= 0;
// Opera 8.0+ (UA detection to detect Blink/v8-powered Opera)
var isFirefox = typeof InstallTrigger !== 'undefined'; // Firefox 1.0+
var isSafari = Object.prototype.toString.call(window.HTMLElement).indexOf('Constructor') > 0;
// At least Safari 3+: "[object HTMLElementConstructor]"
var isChrome = !!window.chrome; // Chrome 1+
var isIE = /*@cc_on!@*/false;

You could use np.where
to find where you have NaN
:
import numpy as np
a = np.array([[ 0, 43, 67, 0, 38],
[ 100, 86, 96, 100, 94],
[ 76, 79, 83, 89, 56],
[ 88, np.nan, 67, 89, 81],
[ 94, 79, 67, 89, 69],
[ 88, 79, 58, 72, 63],
[ 76, 79, 71, 67, 56],
[ 71, 71, np.nan, 56, 100]])
b = np.where(np.isnan(a), 0, a)
In [20]: b
Out[20]:
array([[ 0., 43., 67., 0., 38.],
[ 100., 86., 96., 100., 94.],
[ 76., 79., 83., 89., 56.],
[ 88., 0., 67., 89., 81.],
[ 94., 79., 67., 89., 69.],

[ 76., 79., 71., 67., 56.],
[ 71., 71., 0., 56., 100.]])
Even if it is a little bit late, i solved the PATH problem by removing every space.

works for me now.
Handling database versions is very important part of application development. I assume that you already have class AppDbHelper extending SQLiteOpenHelper
. When you extend it you will need to implement onCreate
and onUpgrade
method.
When onCreate
and onUpgrade
methods called
onCreate
called when app newly installed.onUpgrade
called when app updated. Organizing Database versions
I manage versions in a class methods. Create implementation of interface Migration. E.g. For first version create MigrationV1
class, second version create MigrationV1ToV2
(these are my naming convention)
public interface Migration {
void run(SQLiteDatabase db);//create tables, alter tables
}
Example migration:
public class MigrationV1ToV2 implements Migration{
public void run(SQLiteDatabase db){
//create new tables
//alter existing tables(add column, add/remove constraint)
//etc.
}
}
onCreate
: Since onCreate
will be called when application freshly installed, we also need to execute all migrations(database version updates). So onCreate
will looks like this:
public void onCreate(SQLiteDatabase db){
Migration mV1=new MigrationV1();
//put your first database schema in this class
mV1.run(db);
Migration mV1ToV2=new MigrationV1ToV2();
mV1ToV2.run(db);
//other migration if any
}
onUpgrade
: This method will be called when application is already installed and it is updated to new application version. If application contains any database changes then put all database changes in new Migration class and increment database version.
For example, lets say user has installed application which has database version 1, and now database version is updated to 2(all schema updates kept in MigrationV1ToV2
). Now when application upgraded, we need to upgrade database by applying database schema changes in MigrationV1ToV2
like this:
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
if (oldVersion < 2) {
//means old version is 1
Migration migration = new MigrationV1ToV2();
migration.run(db);
}
if (oldVersion < 3) {
//means old version is 2
}
}
Note: All upgrades (mentioned in
onUpgrade
) in to database schema should be executed inonCreate
