How about
CAST(2229.999 AS DECIMAL(6,2))
to get a decimal with 2 decimal places
In Visual Studio 2019, this can also be configured in Tools -> Options -> General -> View whitespace
Yes, it is possible both in Sublime Text 2 and 3 (which you should really upgrade to if you haven't already). Select View ? Ruler ? 80
(there are several other options there as well). If you like to actually wrap your text at 80 columns, select View ? Word Wrap Column ? 80
. Make sure that View ? Word Wrap
is selected.
To make your selections permanent (the default for all opened files or views), open Preferences ? Settings—User
and use any of the following rules:
{
// set vertical rulers in specified columns.
// Use "rulers": [80] for just one ruler
// default value is []
"rulers": [80, 100, 120],
// turn on word wrap for source and text
// default value is "auto", which means off for source and on for text
"word_wrap": true,
// set word wrapping at this column
// default value is 0, meaning wrapping occurs at window width
"wrap_width": 80
}
These settings can also be used in a .sublime-project
file to set defaults on a per-project basis, or in a syntax-specific .sublime-settings
file if you only want them to apply to files written in a certain language (Python.sublime-settings
vs. JavaScript.sublime-settings
, for example). Access these settings files by opening a file with the desired syntax, then selecting Preferences ? Settings—More ? Syntax Specific—User
.
As always, if you have multiple entries in your settings file, separate them with commas ,
except for after the last one. The entire content should be enclosed in curly braces { }
. Basically, make sure it's valid JSON.
If you'd like a key combo to automatically set the ruler at 80 for a particular view/file, or you are interested in learning how to set the value without using the mouse, please see my answer here.
Finally, as mentioned in another answer, you really should be using a monospace font in order for your code to line up correctly. Other types of fonts have variable-width letters, which means one 80-character line may not appear to be the same length as another 80-character line with different content, and your indentations will look all messed up. Sublime has monospace fonts set by default, but you can of course choose any one you want. Personally, I really like Liberation Mono. It has glyphs to support many different languages and Unicode characters, looks good at a variety of different sizes, and (most importantly for a programming font) clearly differentiates between 0
and O
(digit zero and capital letter oh) and 1
and l
(digit one and lowercase letter ell), which not all monospace fonts do, unfortunately. Version 2.0 and later of the font are licensed under the open-source SIL Open Font License 1.1 (here is the FAQ).
I tried all these solutions on a Grouped Tablix with row spaces and none worked across the entire report. The result was duplicate colored rows and other solutions resulted in alternating columns!
Here is the function I wrote that worked for me using a Column Count:
Private bOddRow As Boolean
Private cellCount as Integer
Function AlternateColorByColumnCount(ByVal OddColor As String, ByVal EvenColor As String, ByVal ColCount As Integer) As String
if cellCount = ColCount Then
bOddRow = Not bOddRow
cellCount = 0
End if
cellCount = cellCount + 1
if bOddRow Then
Return OddColor
Else
Return EvenColor
End If
End Function
For a 7 Column Tablix I use this expression for Row (of Cells) Backcolour:
=Code.AlternateColorByColumnCount("LightGrey","White", 7)

There're few additional methods available as well e.g.: $dte.AddDays(-45).Day
Using the Joda-Time 2.4 library. The DateTimeFormat
class is a factory of DateTimeFormatter
formatters. That class offers a forStyle
method to access formatters appropriate to a Locale
.
DateTimeFormatter formatter = DateTimeFormat.forStyle( "MM" ).withLocale( Java.util.Locale.CANADA_FRENCH );
String output = formatter.print( DateTime.now( DateTimeZone.forID( "America/Montreal" ) ) );
The argument with two letters specifies a format for the date portion and the time portion. Specify a character of 'S' for short style, 'M' for medium, 'L' for long, and 'F' for full. A date or time may be ommitted by specifying a style character '-' HYPHEN.
Note that we specified both a Locale and a time zone. Some people confuse the two.
We need all those pieces to properly generate a string representation of a date-time value.
Try with
ToString("#,##0.###")
Produces:
1234.55678 => 1,234.556
1234 => 1,234
In VS2017 you can change it after selecting your coding language in the settings menu. There is an option called "new Lines" in the "Formatting"-submenu.
The most recent and in my opinion preferred approach is the f-string
:
''.join(f'{i:02x}' for i in [1, 15, 255])
The old format style was the %
-syntax:
['%02x'%i for i in [1, 15, 255]]
The more modern approach is the .format
method:
['{:02x}'.format(i) for i in [1, 15, 255]]
More recently, from python 3.6 upwards we were treated to the f-string
syntax:
[f'{i:02x}' for i in [1, 15, 255]]
Note that the f'{i:02x}'
works as follows.
:
is the input or variable to format. x
indicates that the string should be hex. f'{100:02x}'
is '64'
and f'{100:02d}'
is '1001'
.02
indicates that the string should be left-filled with 0
's to length 2
. f'{100:02x}'
is '64'
and f'{100:30x}'
is ' 64'
.Here's another solution with strtok and str_pad:
$num = 520.00
strtok(round($num, 2), '.') . '.' . str_pad(strtok('.'), 2, '0')
Late answer, but hopefully worthwhile: The Poor Man's T-SQL Formatter is an open-source (free) T-SQL formatter with complete T-SQL batch/script support (any DDL, any DML), SSMS Plugin, command-line bulk formatter, and other options.
It's available for immediate/online use at http://poorsql.com, and just today graduated to "version 1.0" (it was in beta version for a few months), having just acquired support for MERGE
statements, OUTPUT
clauses, and other finicky stuff.
The SSMS Add-in allows you to set your own hotkey (default is Ctrl-K, Ctrl-F, to match Visual Studio), and formats the entire script or just the code you have selected/highlighted, if any. Output formatting is customizable.
In SSMS 2008 it combines nicely with the built-in intelli-sense, effectively providing more-or-less the same base functionality as Red Gate's SQL Prompt (SQL Prompt does, of course, have extra stuff, like snippets, quick object scripting, etc).
Feedback/feature requests are more than welcome, please give it a whirl if you get the chance!
Disclosure: This is probably obvious already but I wrote this library/tool/site, so this answer is also shameless self-promotion :)
Use this function and don't sweat having to remember if your JSON is a str
or dict
again - just look at the pretty print:
import json
def pp_json(json_thing, sort=True, indents=4):
if type(json_thing) is str:
print(json.dumps(json.loads(json_thing), sort_keys=sort, indent=indents))
else:
print(json.dumps(json_thing, sort_keys=sort, indent=indents))
return None
pp_json(your_json_string_or_dict)
Well I was searching for an easy way. And find out on medium.
First to copy the json text and validate it on jsonlint or something similar. Then to copy from jsonlint, already the json is formatted. And paste the code on Xcode with preserving the format, shortcut shift + option + command + v
Just do String str = System.out.printf("%.2f", val).replace(",", ".");
if you want to ensure that independently of the Locale of the user, you will always get / display a "." as decimal separator. This is a must if you don't want to make your program crash if you later do some kind of conversion like float f = Float.parseFloat(str);
You can find a list of formatting escapes on this page.
%d
is a signed integer, while %u
is an unsigned integer. Pointers (when treated as numbers) are usually non-negative.
If you actually want to display a pointer, use the %p
format specifier.
First import NumberFormat
. Then add this:
NumberFormat currencyFormatter = NumberFormat.getCurrencyInstance();
This will give you two decimal places and put a dollar sign if it's dealing with currency.
import java.text.NumberFormat;
public class Payroll
{
/**
* @param args the command line arguments
*/
public static void main(String[] args)
{
int hoursWorked = 80;
double hourlyPay = 15.52;
double grossPay = hoursWorked * hourlyPay;
NumberFormat currencyFormatter = NumberFormat.getCurrencyInstance();
System.out.println("Your gross pay is " + currencyFormatter.format(grossPay));
}
}
Using pandas: pd.Timestamp("today").strftime("%m/%d/%Y")
We can make it by :
Ctrl+i or Ctrl+Shift+F
This can be used to find all the numeric values (even those formatted as text) in a sheet and convert them to single (CSng function).
For Each r In Sheets("Sheet1").UsedRange.SpecialCells(xlCellTypeConstants)
If IsNumeric(r) Then
r.Value = CSng(r.Value)
r.NumberFormat = "0.00"
End If
Next
"{:.5g}".format(x)
I use this to format floats to trail zeros.
Looks like moment.js is the most popular and with active development:
moment("2010-01-01T05:06:07", moment.ISO_8601);
Not quite sure why it's not mentioned more online (or on this thread), but the Babel package (and Django utilities) from the Edgewall guys is awesome for currency formatting (and lots of other i18n tasks). It's nice because it doesn't suffer from the need to do everything globally like the core Python locale module.
The example the OP gave would simply be:
>>> import babel.numbers
>>> import decimal
>>> babel.numbers.format_currency( decimal.Decimal( "188518982.18" ), "GBP" )
£188,518,982.18
You can use the string formatting mini language:
def binary(num, pre='0b', length=8, spacer=0):
return '{0}{{:{1}>{2}}}'.format(pre, spacer, length).format(bin(num)[2:])
Demo:
print binary(1)
Output:
'0b00000001'
EDIT: based on @Martijn Pieters idea
def binary(num, length=8):
return format(num, '#0{}b'.format(length + 2))
preg_replace("/[[:blank:]]+/"," ",$input)
Pretty easy to do this across multiple cells, without having to add '%' to each individually.
Select all the cells you want to change to percent, right Click, then format Cells, choose Custom. Type in 0.0\%
.
Consecutive string literals are joined by the compiler, and parenthesized expressions are considered to be a single line of code:
logger.info("Skipping {0} because it's thumbnail was "
"already in our system as {1}.".format(line[indexes['url']],
video.title))
var formatNumber = function (number) {
var splitNum;
number = Math.abs(number);
number = number.toFixed(2);
splitNum = number.split('.');
splitNum[0] = splitNum[0].replace(/\B(?=(\d{3})+(?!\d))/g, ",");
return splitNum.join(".");
}
EDIT: The function only work with positive number. for exmaple:
var number = -123123231232;
formatNumber(number)
Output: "123,123,231,232"
But to answer the question above toLocaleString()
method just solves the problem.
var number = 123123231232;
number.toLocaleString()
Output: "123,123,231,232"
Cheer!
java.text.NumberFormat is probably what you want.
Or, if for some reason you don't like any of the more sensible answers, just discard everything to the right of (and including) the space.
Suppose your "Don't Check" list is on Sheet2 in cells A1:A100
, say, and your current client IDs are in Sheet1 in Column A.
What you would do is:
Conditional Formatting
> New Rule
> Use a Formula to determine which cells to format
=ISNUMBER(MATCH($A1,Sheet2!$A$1:$A$100,0))
and select how you want those rows formattedAnd that should do the trick.
Instead of using string interpolation you could simply format the DateTime using the ToString("u")
method and concatenate that with the rest of the string:
$startTime = Get-Date
Write-Host "The script was started " + $startTime.ToString("u")
/* Just Do the following, */
echo money_format("%(#10n","123.45"); //Output $ 123.45
/* If Negative Number -123.45 */
echo money_format("%(#10n","-123.45"); //Output ($ 123.45)
if (timeSpan.TotalDays < 1)
return timeSpan.ToString(@"hh\:mm\:ss");
return timeSpan.TotalDays < 2
? timeSpan.ToString(@"d\ \d\a\y\ hh\:mm\:ss")
: timeSpan.ToString(@"d\ \d\a\y\s\ hh\:mm\:ss");
All literal characters must be escaped.
I'm guessing that you're doing some sort of localization, so have a look at this script.
print "[%s]"%", ".join(map(str,yourlist))
This will avoid the rounding errors in the binary representation when printed, without introducing a fixed precision constraint (like formating with "%.2f"
):
[9.0, 0.053, 0.0325754, 0.0108928, 0.0557025, 0.0793303]
You can't really do calculations in the formatting features of Excel. You can use something like the following to do a rough estimation though:
[<500000]#,##0" B";[<500000000]#,##0,," MB";#,##0,,," GB"
If you don't want to use RegEx (which seems highly unnecessary given your problem), perhaps you should try something like this:
public String modified(final String input){
final StringBuilder builder = new StringBuilder();
for(final char c : input.toCharArray())
if(Character.isLetterOrDigit(c))
builder.append(Character.isLowerCase(c) ? c : Character.toLowerCase(c));
return builder.toString();
}
It loops through the underlying char[]
in the String
and only appends the char
if it is a letter or digit (filtering out all symbols, which I am assuming is what you are trying to accomplish) and then appends the lower case version of the char
.
Both solutions workto simulate printf, but in a different way. For instance, to convert a value to a hex string, you have the 2 following solutions:
with format()
, closest to sprintf()
:
final static String HexChars = "0123456789abcdef";
public static String getHexQuad(long v) {
String ret;
if(v > 0xffff) ret = getHexQuad(v >> 16); else ret = "";
ret += String.format("%c%c%c%c",
HexChars.charAt((int) ((v >> 12) & 0x0f)),
HexChars.charAt((int) ((v >> 8) & 0x0f)),
HexChars.charAt((int) ((v >> 4) & 0x0f)),
HexChars.charAt((int) ( v & 0x0f)));
return ret;
}
with replace(char oldchar , char newchar)
, somewhat faster but pretty limited:
...
ret += "ABCD".
replace('A', HexChars.charAt((int) ((v >> 12) & 0x0f))).
replace('B', HexChars.charAt((int) ((v >> 8) & 0x0f))).
replace('C', HexChars.charAt((int) ((v >> 4) & 0x0f))).
replace('D', HexChars.charAt((int) ( v & 0x0f)));
...
There is a third solution consisting of just adding the char to ret
one by one (char are numbers that add to each other!) such as in:
...
ret += HexChars.charAt((int) ((v >> 12) & 0x0f)));
ret += HexChars.charAt((int) ((v >> 8) & 0x0f)));
...
...but that'd be really ugly.
vim
also can convert files from UNIX to DOS format. For example:
vim hello.txt <<EOF
:set fileformat=dos
:wq
EOF
Just a quick tip for people stumbling across this thread; there is one more place where this setting can also be set, in your project!
Eclipse supports project-specific settings, and some projects will use their own, un-managed tabs/spaces settings, which won't show up anywhere except the current project Properties.
This can be managed through:
This will generally only be an issue if you import someone else's code into your Eclipse.
PHP has a function called money_format
for doing this. Read about this here.
I don't know if maybe it's a difference in Excel version but this question is 6 years old and the accepted answer didn't help me so this is what I figured out:
Under Conditional Formatting > Manage Rules:
$A2<$B2
$B$2:$B$100
(assuming you have 100 rows)This worked for me in Excel 2016.
Assume that you have dynamic currency precision
value => 1.002431
currency precision => 3
`result => 1.002
CAST(Floor(your_float_value) AS VARCHAR) + '.' + REPLACE(STR(FLOOR((your_float_value FLOOR(your_float_value)) * power(10,cu_precision)), cu_precision), SPACE(1), '0')
If performance is important in your case you could do it yourself with less overhead compared to the String.format
function:
/**
* @param in The integer value
* @param fill The number of digits to fill
* @return The given value left padded with the given number of digits
*/
public static String lPadZero(int in, int fill){
boolean negative = false;
int value, len = 0;
if(in >= 0){
value = in;
} else {
negative = true;
value = - in;
in = - in;
len ++;
}
if(value == 0){
len = 1;
} else{
for(; value != 0; len ++){
value /= 10;
}
}
StringBuilder sb = new StringBuilder();
if(negative){
sb.append('-');
}
for(int i = fill; i > len; i--){
sb.append('0');
}
sb.append(in);
return sb.toString();
}
Performance
public static void main(String[] args) {
Random rdm;
long start;
// Using own function
rdm = new Random(0);
start = System.nanoTime();
for(int i = 10000000; i != 0; i--){
lPadZero(rdm.nextInt(20000) - 10000, 4);
}
System.out.println("Own function: " + ((System.nanoTime() - start) / 1000000) + "ms");
// Using String.format
rdm = new Random(0);
start = System.nanoTime();
for(int i = 10000000; i != 0; i--){
String.format("%04d", rdm.nextInt(20000) - 10000);
}
System.out.println("String.format: " + ((System.nanoTime() - start) / 1000000) + "ms");
}
Result
Own function: 1697ms
String.format: 38134ms
function padToFour(number) {
if (number<=9999) { number = ("000"+number).slice(-4); }
return number;
}
Something like that?
Bonus incomprehensible-but-slicker single-line ES6 version:
let padToFour = number => number <= 9999 ? `000${number}`.slice(-4) : number;
ES6isms:
let

’s functional scoping)=>

you can omit the braces and the return
keyword and simply use the expressionThis function could transform the data to percentages by columns
percent.colmns = function(base, columnas = 1:ncol(base), filas = 1:nrow(base)){
base2 = base
for(j in columnas){
suma.c = sum(base[,j])
for(i in filas){
base2[i,j] = base[i,j]*100/suma.c
}
}
return(base2)
}
For my blog I use http://hilite.me/ to format source code. It supports lots of formats and outputs rather clean html. But if you have lots of code snippets then you have to do a lot of copy paste. For formatting Python code I've also used Pygments (blog post).
Say you want to change 2019-12-20 10:50 AM GMT+6:00 to 2019-12-20 10:50 AM first of all you have to understand the date format first one date format is yyyy-MM-dd hh:mm a zzz and second one date format will be yyyy-MM-dd hh:mm a
just return a string from this function like.
public String convertToOnlyDate(String currentDate) {
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd hh:mm a ");
Date date;
String dateString = "";
try {
date = dateFormat.parse(currentDate);
System.out.println(date.toString());
dateString = dateFormat.format(date);
} catch (ParseException e) {
e.printStackTrace();
}
return dateString;
}
This function will return your desire answer. If you want to customize more just add or remove component from the date format.
Your format specifier is incorrect. From the printf()
man page on my machine:
0
A zero '0
' character indicating that zero-padding should be used rather than blank-padding. A '-
' overrides a '0
' if both are used;Field Width: An optional digit string specifying a field width; if the output string has fewer characters than the field width it will be blank-padded on the left (or right, if the left-adjustment indicator has been given) to make up the field width (note that a leading zero is a flag, but an embedded zero is part of a field width);
Precision: An optional period, '
.
', followed by an optional digit string giving a precision which specifies the number of digits to appear after the decimal point, for e and f formats, or the maximum number of characters to be printed from a string; if the digit string is missing, the precision is treated as zero;
For your case, your format would be %09.3f
:
#include <stdio.h>
int main(int argc, char **argv)
{
printf("%09.3f\n", 4917.24);
return 0;
}
Output:
$ make testapp
cc testapp.c -o testapp
$ ./testapp
04917.240
Note that this answer is conditional on your embedded system having a printf()
implementation that is standard-compliant for these details - many embedded environments do not have such an implementation.
This is an old post but regardless, you can also get boldface and italic characters by leveraging utf-32. There are even greek and math symbols that can be used as well as the roman alphabet.
public class DateTimeFilter : ActionFilterAttribute
{
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
if (filterContext.HttpContext.Request.RequestType == "GET")
{
foreach (var parameter in filterContext.ActionParameters)
{
var properties = parameter.Value.GetType().GetProperties();
foreach (var property in properties)
{
Type type = Nullable.GetUnderlyingType(property.PropertyType) ?? property.PropertyType;
if (property.PropertyType == typeof(System.DateTime) || property.PropertyType == typeof(DateTime?))

}
}
To pad int i
to match the string length of int x
, when both can be negative:
i.ToString().PadLeft((int)Math.Log10(Math.Abs(x < 0 ? x * 10 : x)) + 1, '0')
If you're using MySQL and want the database itself to perform the conversion, use this:
If you prefer to format using Java, use this:
SimpleDateFormat dateFormat = new SimpleDateFormat("M/dd/yyyy");
dateFormat.format( new Date() );
import yaml
data = dict(
A = 'a',
B = dict(
C = 'c',
D = 'd',
E = 'e',
)
)
with open('data.yml', 'w') as outfile:
yaml.dump(data, outfile, default_flow_style=False)
The default_flow_style=False
parameter is necessary to produce the format you want (flow style), otherwise for nested collections it produces block style:
A: a
B: {C: c, D: d, E: e}
You can use a function into a repeater like you said, but notice that the DataBinder.Eval returns an object and you have to cast it to a DateTime.
You also can format your field inline:
<%# ((DateTime)DataBinder.Eval(Container.DataItem,"publishedDate")).ToString("yyyy-MMM-dd") %>
If you use ASP.NET 2.0 or newer you can write this as below:
<%# ((DateTime)Eval("publishedDate")).ToString("yyyy-MMM-dd") %>
Another option is to bind the value to label at OnItemDataBound event.
This version produces JSON that is more compact and in my opinion more readable since you can see more at one time. It does this by formatting the deepest layer inline or like a compact array structure.
The code has no dependencies but is more complex.

The function allows you to specify a starting point for the indentation because I use this as part of a process that assembles very large JSON formatted backup files.
Most of the answers are/were valid. The new JAVA API modification for Date handling made sure that some earlier ambiguity in java date handling is reduced.
You will get a deprecated message for similar calls.
new Date() // deprecated
The above call had the developer to assume that a new Date object will give the Date object with current timestamp. This behavior is not consistent across other Java API classes.
The new way of doing this is using the Calendar Instance.
new SimpleDateFormat("yyyy-MM-dd").format(Calendar.getInstance().getTime()
Here too the naming convention is not perfect but this is much organised. For a person like me who has a hard time mugging up things but would never forget something if it sounds/appears logical, this is a good approach.
This is more synonymous to real life
One more way to do this is using Joda time API
new DateTime().toString("yyyy-MM-dd")
or the much obvious
new DateTime(Calendar.getInstance().getTime()).toString("yyyy-MM-dd")
both will return the same result.
Following JavaScript function handles ', ", \b, \t, \n, \f or \r equivalent of php function addslashes().
function addslashes(string) {
return string.replace(/\\/g, '\\\\').
replace(/\u0008/g, '\\b').
replace(/\t/g, '\\t').
replace(/\n/g, '\\n').
replace(/\f/g, '\\f').
replace(/\r/g, '\\r').
replace(/'/g, '\\\'').
replace(/"/g, '\\"');
}
Retrieve year, month, and day, and then put them together. Straight, simple, and accurate.
function formatDate(date) {_x000D_
var year = date.getFullYear().toString();_x000D_
var month = (date.getMonth() + 101).toString().substring(1);_x000D_
var day = (date.getDate() + 100).toString().substring(1);_x000D_
return year + "-" + month + "-" + day;_x000D_
}_x000D_
_x000D_
//Usage example:_x000D_
alert(formatDate(new Date()));
_x000D_
Perl Code for Unix systems:
# Capture date from shell
my $current_date = `date +"%m/%d/%Y"`;
# Remove newline character
$current_date = substr($current_date,0,-1);
print $current_date, "\n";
I think I figured it out. Here's what I did (perhaps not the most elegant solution - suggestions on how to imp[rove this are very much welcome)
#names of columns in data frame
cols <- names(DF)
# character variables
cols.char <- c("fx_code","date")
#numeric variables
cols.num <- cols[!cols %in% cols.char]
DF.char <- DF[cols.char]
DF.num <- as.data.frame(lapply(DF[cols.num],as.numeric))
DF2 <- cbind(DF.char, DF.num)
You can do this in the 'Conditional Formatting' tool in the Home tab of Excel 2010.
Assuming the existing rule is 'Use a formula to dtermine which cells to format':
Edit the existing rule, so that the 'Formula' refers to relative rows and columns (i.e. remove $s), and then in the 'Applies to' box, click the icon to make the sheet current and select the cells you want the formatting to apply to (absolute cell references are ok here), then go back to the tool panel and click Apply.
This will work assuming the relative offsets are appropriate throughout your desired apply-to range.
You can copy conditional formatting from one cell to another or a range using copy and paste-special with formatting only, assuming you do not mind copying the normal formats.
Do this:
date('Y-m-d', strtotime('dd/mm/yyyy'));
But make sure 'dd/mm/yyyy' is the actual date.
As the top answer here is suggesting something wrong (or at least too complicated), I feel this should be updated, although the question is quite old:
When using String resources in Android, you just have to call getString(...)
from Java code or use android:text="@string/..."
in your layout XML.
Even if you want to use HTML markup in your Strings, you don't have to change a lot:
The only characters that you need to escape in your String resources are:
"
becomes \"
'
becomes \'
&
becomes &
or &
That means you can add your HTML markup without escaping the tags:
<string name="my_string"><b>Hello World!</b> This is an example.</string>
However, to be sure, you should only use <b>
, <i>
and <u>
as they are listed in the documentation.
If you want to use your HTML strings from XML, just keep on using android:text="@string/..."
, it will work fine.
The only difference is that, if you want to use your HTML strings from Java code, you have to use getText(...)
instead of getString(...)
now, as the former keeps the style and the latter will just strip it off.
It's as easy as that. No CDATA, no Html.fromHtml(...)
.
You will only need Html.fromHtml(...)
if you did encode your special characters in HTML markup. Use it with getString(...)
then. This can be necessary if you want to pass the String to String.format(...)
.
This is all described in the docs as well.
Edit:
There is no difference between getText(...)
with unescaped HTML (as I've proposed) or CDATA
sections and Html.fromHtml(...)
.
See the following graphic for a comparison:
Not to resurrect an old question but figured I might offer at least a slightly easier to use method, if a little more complicated of a setup.
So if we create a new custom formatter we can use the simpler formatting of string.Format
without having to convert our phone number to a long
So first lets create the custom formatter:
using System;
using System.Globalization;
using System.Text;
namespace System
{
/// <summary>
/// A formatter that will apply a format to a string of numeric values.
/// </summary>
/// <example>
/// The following example converts a string of numbers and inserts dashes between them.
/// <code>
/// public class Example
/// {
/// public static void Main()
/// {
/// string stringValue = "123456789";
///
/// Console.WriteLine(String.Format(new NumericStringFormatter(),
/// "{0} (formatted: {0:###-##-####})",stringValue));
/// }
/// }
/// // The example displays the following output:
/// // 123456789 (formatted: 123-45-6789)
/// </code>
/// </example>
public class NumericStringFormatter : IFormatProvider, ICustomFormatter
{
/// <summary>
/// Converts the value of a specified object to an equivalent string representation using specified format and
/// culture-specific formatting information.
/// </summary>
/// <param name="format">A format string containing formatting specifications.</param>
/// <param name="arg">An object to format.</param>
/// <param name="formatProvider">An object that supplies format information about the current instance.</param>
/// <returns>
/// The string representation of the value of <paramref name="arg" />, formatted as specified by
/// <paramref name="format" /> and <paramref name="formatProvider" />.
/// </returns>
/// <exception cref="System.NotImplementedException"></exception>
public string Format(string format, object arg, IFormatProvider formatProvider)
{
var strArg = arg as string;
// If the arg is not a string then determine if it can be handled by another formatter
if (strArg == null)
{
try
{
return HandleOtherFormats(format, arg);
}
catch (FormatException e)
{
throw new FormatException(string.Format("The format of '{0}' is invalid.", format), e);
}
}
// If the format is not set then determine if it can be handled by another formatter
if (string.IsNullOrEmpty(format))
{
try
{
return HandleOtherFormats(format, arg);
}
catch (FormatException e)
{
throw new FormatException(string.Format("The format of '{0}' is invalid.", format), e);
}
}
var sb = new StringBuilder();
var i = 0;
foreach (var c in format)
{
if (c == '#')
{
if (i < strArg.Length)
{
sb.Append(strArg[i]);
}
i++;
}
else
{
sb.Append(c);
}
}
return sb.ToString();
}
/// <summary>
/// Returns an object that provides formatting services for the specified type.
/// </summary>
/// <param name="formatType">An object that specifies the type of format object to return.</param>
/// <returns>
/// An instance of the object specified by <paramref name="formatType" />, if the
/// <see cref="T:System.IFormatProvider" /> implementation can supply that type of object; otherwise, null.
/// </returns>
public object GetFormat(Type formatType)
{
// Determine whether custom formatting object is requested.
return formatType == typeof(ICustomFormatter) ? this : null;
}
private string HandleOtherFormats(string format, object arg)
{
if (arg is IFormattable)
return ((IFormattable)arg).ToString(format, CultureInfo.CurrentCulture);
else if (arg != null)
return arg.ToString();
else
return string.Empty;
}
}
}
So then if you want to use this you would do something this:
String.Format(new NumericStringFormatter(),"{0:###-###-####}", i["MyPhone"].ToString());
Some other things to think about:
Right now if you specified a longer formatter than you did a string to format it will just ignore the additional # signs. For example this String.Format(new NumericStringFormatter(),"{0:###-###-####}", "12345");
would result in 123-45-
so you might want to have it take some kind of possible filler character in the constructor.
Also I didn't provide a way to escape a # sign so if you wanted to include that in your output string you wouldn't be able to the way it is right now.
The reason I prefer this method over Regex is I often have requirements to allow users to specify the format themselves and it is considerably easier for me to explain how to use this format than trying to teach a user regex.
Also the class name is a bit of misnomer since it actually works to format any string as long as you want to keep it in the same order and just inject characters inside of it.
for flexibility with different formats, use:
$dt = DateTime::createFromFormat('m/d/Y H:i:s', '08/04/2010 22:15:00');
echo $dt->format('g:i A')
Check the php manual for additional format options.
Try this,
import java.text.ParseException;
import java.text.SimpleDateFormat;
public class Date
{
public static void main(String[] args)
{
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String strDate = "2013-05-14 17:07:21";
try
{
java.util.Date dt = sdf.parse(strDate);
System.out.println(sdf.format(dt));
}
catch (ParseException pe)
{
pe.printStackTrace();
}
}
}
Output:
2013-05-14 17:07:21

This is fast & works for whatever length.
public static String prefixZeros(String value, int len) {
char[] t = new char[len];
int l = value.length();
int k = len-l;
for(int i=0;i<k;i++) { t[i]='0'; }
value.getChars(0, l, t, k);
return new String(t);
}
For a general solution that works regardless of how many digits are in data$anim
, use the sprintf
function. It works like this:
sprintf("%04d", 1)
# [1] "0001"
sprintf("%04d", 104)
# [1] "0104"
sprintf("%010d", 104)
# [1] "0000000104"
In your case, you probably want: data$anim <- sprintf("%06d", data$anim)
This is the only thing I've found for JavaScript formatting in Dreamweaver. Not many options, but it seems to work well.
JavaScript source format extension for dreamweaver: Adobe CFusion
SELECT CONVERT(VARCHAR(10), GETDATE(), 105) + ' ' + CONVERT(VARCHAR(10), GETDATE(), 108)
Here's a Go version. For simplicity, I've only included the binary output case.
func sizeOf(bytes int64) string {
const unit = 1024
if bytes < unit {
return fmt.Sprintf("%d B", bytes)
}
fb := float64(bytes)
exp := int(math.Log(fb) / math.Log(unit))
pre := "KMGTPE"[exp-1]
div := math.Pow(unit, float64(exp))
return fmt.Sprintf("%.1f %ciB", fb / div, pre)
}
here is another approach
decimal decimalRounded = Decimal.Parse(Debitvalue.ToString("0.00"));
Some great answers above, using that info here is what I did today to solve the same issue:
$to_array = explode(',', $to);
foreach($to_array as $address)
{
$mail->addAddress($address, 'Web Enquiry');
}
Here is how I solve this. I just pipe the output to Out-String and then pass that output to the .NET Trim function:
(gci | ft -HideTableHeaders | Out-String).Trim()
This will strip out the line breaks before and after the table.
You can also use TrimStart to just take care of the header's line break if you still want the trailing line breaks.
(gci | ft -HideTableHeaders | Out-String).TrimStart()
git log --pretty=format:'%h %ad %s (%an)' --date=short
or
git log --pretty=format:'%h %ad %s | %an' --date=short
...riffing on cdunn2001's answer above: I'd lose the author's e=mail and include just the author's name, as per Jesper and knittl, but in keeping with cdunn2001's idea of maintaining output in columns of constant width for ease of reading (great idea!). In lieu of a separate left justified column for author name, however, I wrap that flag at the end of the command with a parentheses or offset it with a pipe. (Could really be any character that serves as a visual aid in reading the output...albeit might make sense to avoid back or forward slashes in order to reduce confusing the output with a directory or something.)

Code Formatting Shortcut:
VSCode on Windows - Shift + Alt + F
VSCode on MacOS - Shift + Option + F
VSCode on Ubuntu - Ctrl + Shift + I
You can also customize this shortcut using preference setting if needed.
column selection with keyboard Ctrl + Shift + Alt + Arrow
As in this answer to a similar question, there is no need to hack settings. It is much simpler to write:
print(foo.to_string())
You can use double open brackets and double closing brackets which will only show one bracket on your page.
Update of some answer around, difference is - function will properly accept std::string for %s
namespace format_helper
{
template <class Src>
inline Src cast(Src v)
{
return v;
}
inline const char *cast(const std::string& v)
{
return v.c_str();
}
};
template <typename... Ts>
inline std::string stringfmt (const std::string &fmt, Ts&&... vs)
{
using namespace format_helper;
char b;
size_t required = std::snprintf(&b, 0, fmt.c_str(), cast(std::forward<Ts>(vs))...);//not counting the terminating null character.
std::string result;
//because we use string as container, it adds extra 0 automatically
result.resize(required , 0);
//and snprintf will use n-1 bytes supplied
std::snprintf(const_cast<char*>(result.data()), required + 1, fmt.c_str(), cast(std::forward<Ts>(vs))...);
return result;
}

This kind of this is always a pain in Excel, you have to convert the values using a function because once Excel converts the cells to Time they are stored internally as numbers. Here is the best way I know how to do it:
I'll assume that your times are in column A starting at row 1. In cell B1 enter this formula: =TEXT(A1,"hh:mm:ss AM/PM")
, drag the formula down column B to the end of your data in column A. Select the values from column B, copy, go to column C and select "Paste Special", then select "Values". Select the cells you just copied into column C and format the cells as "Text".
If we are talking Visual Studio Code nowadays you set a default formatter in your settings.json
:
// Defines a default formatter which takes precedence over all other formatter settings.
// Must be the identifier of an extension contributing a formatter.
"editor.defaultFormatter": null,
Point to the identifier of any installed extension, i.e.
"editor.defaultFormatter": "esbenp.prettier-vscode"
You can also do so format-specific:
"[html]": {
"editor.defaultFormatter": "esbenp.prettier-vscode"
},
"[scss]": {
"editor.defaultFormatter": "esbenp.prettier-vscode"
},
"[sass]": {
"editor.defaultFormatter": "michelemelluso.code-beautifier"
},
Also see here.
You could also assign other keys for different formatters in your keyboard shortcuts (keybindings.json
). By default, it reads:
{
"key": "shift+alt+f",
"command": "editor.action.formatDocument",
"when": "editorHasDocumentFormattingProvider && editorHasDocumentFormattingProvider && editorTextFocus && !editorReadonly"
}
Lastly, if you decide to use the Prettier plugin and prettier.rc
, and you want for example different indentation for html, scss, json...
{
"semi": true,
"singleQuote": false,

"useTabs": false,

Try creating a new pivot table, and not just refreshing.
I had a case where I forgot to add in a few dates. After adding them in I updated the pivot table range and hit refresh. They appeared at the end of the pivot table, out of order. I then tried to simply create a new pivot table and the dates where all in order.
Or you can do this:
<table>
<tr>
<td><b>Return:</b></td>
<td><input id="return1" name='return1'
class=" input input-sm" style="width:150px"
type="text" value='8/28/2013'></td>
</tr>
</table>
I tried every one of the suggestions above and none of them worked. I don't want to pick a fixed number of columns in the 12 column grid. I want the prompt, and the input right after it, and I want the columns to stretch as needed.
Yes, I know, that is against what bootstrap is all about. And you should NEVER use a table. Because DIV is so much better than tables. But the problem is that tables, rows, and cells actually WORK.
YES - I REALLY DO know that there are CSS zealots, and the knee-jerk reaction is never never never use TABLE, TR, and TD. Yes, I do know that DIV class="table" with DIV class="row" and DIV class="cell" is much much better. Except when it doesn't work, and there are many cases. I don't believe that people should blindly ignore those situations. There are times that the TABLE/TR/TD will work just fine, and there is not reason to use a more complicated and more fragile approach just because it is considered more elegant. A developer should understand what the benefits of the various approaches are, and the tradeoffs, and there is no absolute rule that DIVs are better.
"Case in point - based on this discussion I converted a few existing tds and trs to divs. 45 minutes messing about with it trying to get everything to line up next to each other and I gave up. TDs back in 10 seconds later - works - straight away - on all browsers, nothing more to do. Please try to make me understand - what possible justification do you have for wanting me to do it any other way!" See [https://stackoverflow.com/a/4278073/1758051]
And this: "
Layout should be easy. The fact that there are articles written on how to achieve a dynamic three column layout with header and footer in CSS shows that it is a poor layout system. Of course you can get it to work, but there are literally hundreds of articles online about how to do it. There are pretty much no such articles for a similar layout with tables because it's patently obvious. No matter what you say against tables and in favor of CSS, this one fact undoes it all: a basic three column layout in CSS is often called "The Holy Grail"." [https://stackoverflow.com/a/4964107/1758051]
I have yet to see a way to force DIVs to always line up in a column in all situations. I keep getting shown trivial examples that don't really run into the problems. "Responsive" is about providing a way that they will not always line up in a column. However, if you really want a column, you can waste hours trying to get DIV to work. Sometimes, you need to use appropriate technology no matter what the zealots say.
If we have built in functions to convert your integer values to COLOR then why to worry.
string hexValue = string.Format("{0:X}", intColor);
Color brushes = System.Drawing.ColorTranslator.FromHtml("#"+hexValue);
You can do
JLabel l = new JLabel("<html><p>Hello World! blah blah blah</p></html>", SwingConstants.CENTER);
and it will automatically wrap it where appropriate.
Since I just learned about this cool thing(indexing into lists from within a format string) I'm adding to this old question.
s = '{x[0]} BLAH {x[1]} FOO {x[2]} BAR'
x = ['1', '2', '3']
print (s.format (x=x))
Output:
1 BLAH 2 FOO 3 BAR
However, I still haven't figured out how to do slicing(inside of the format string '"{x[2:4]}".format...
,) and would love to figure it out if anyone has an idea, however I suspect that you simply cannot do that.
This code would return the current date and time:
public String getCurrDate()
{
String dt;
Date cal = Calendar.getInstance().getTime();
dt = cal.toLocaleString();
return dt;
}
The YUI codebase uses the following formmating:
format: function(nData, oConfig) {
oConfig = oConfig || {};
if(!YAHOO.lang.isNumber(nData)) {
nData *= 1;
}
if(YAHOO.lang.isNumber(nData)) {
var sOutput = nData + "";
var sDecimalSeparator = (oConfig.decimalSeparator) ? oConfig.decimalSeparator : ".";
var nDotIndex;
// Manage decimals
if(YAHOO.lang.isNumber(oConfig.decimalPlaces)) {
// Round to the correct decimal place
var nDecimalPlaces = oConfig.decimalPlaces;
var nDecimal = Math.pow(10, nDecimalPlaces);
sOutput = Math.round(nData*nDecimal)/nDecimal + "";
nDotIndex = sOutput.lastIndexOf(".");
if(nDecimalPlaces > 0) {
// Add the decimal separator
if(nDotIndex < 0) {
sOutput += sDecimalSeparator;
nDotIndex = sOutput.length-1;
}
// Replace the "."
else if(sDecimalSeparator !== "."){
sOutput = sOutput.replace(".",sDecimalSeparator);
}
// Add missing zeros
while((sOutput.length - 1 - nDotIndex) < nDecimalPlaces) {
sOutput += "0";
}
}
}
// Add the thousands separator
if(oConfig.thousandsSeparator) {
var sThousandsSeparator = oConfig.thousandsSeparator;
nDotIndex = sOutput.lastIndexOf(sDecimalSeparator);
nDotIndex = (nDotIndex > -1) ? nDotIndex : sOutput.length;
var sNewOutput = sOutput.substring(nDotIndex);
var nCount = -1;
for (var i=nDotIndex; i>0; i--) {
nCount++;
if ((nCount%3 === 0) && (i !== nDotIndex)) {
sNewOutput = sThousandsSeparator + sNewOutput;
}
sNewOutput = sOutput.charAt(i-1) + sNewOutput;
}
sOutput = sNewOutput;
}
// Prepend prefix
sOutput = (oConfig.prefix) ? oConfig.prefix + sOutput : sOutput;
// Append suffix
sOutput = (oConfig.suffix) ? sOutput + oConfig.suffix : sOutput;
return sOutput;
}
// Still not a Number, just return unaltered
else {
return nData;
}
}
it would need editing as the YUI library is configurable, like replacing oConfig.decimalSeparator with "."
JSON.stringify
takes more optional arguments.
Try:
JSON.stringify({a:1,b:2,c:{d:1,e:[1,2]}}, null, 4); // Indented 4 spaces
JSON.stringify({a:1,b:2,c:{d:1,e:[1,2]}}, null, "\t"); // Indented with tab

How can I beautify JSON programmatically?
Should work in modern browsers, and it is included in json2.js if you need a fallback for browsers that don't support the JSON helper functions. For display purposes, put the output in a <pre>
tag to get newlines to show.
I know this is an old question but for people searching for this solution it's worth noting that you should not use append() to add content to a textarea. the append() method targets innerHTML not the value of the textarea. The content may appear in the textarea but it will not be added to the element's form value.
As noted above using:
$('#textarea').val($('#textarea').val()+'new content');
will work fine.
Also try dojo.number which has built-in localization support. It is a much closer analog to Java's NumberFormat/DecimalFormat
Short oneliner for CamelCases when you have spaces also included (doesn't work correctly if you have a word inbetween with small starting-letter):
a = "Test String"
a.gsub(' ', '').underscore
=> "test_string"
<asp:RadioButtonList ID="rbn" runat="server" RepeatLayout="Table" RepeatColumns="2"
Width="100%" >
<asp:ListItem Text="1"></asp:ListItem>
<asp:ListItem Text="2"></asp:ListItem>
<asp:ListItem Text="3"></asp:ListItem>
<asp:ListItem Text="4"></asp:ListItem>
</asp:RadioButtonList>
Another way to use gson:
String json_String_to_print = ...
Gson gson = new GsonBuilder().setPrettyPrinting().create();
JsonParser jp = new JsonParser();
return gson.toJson(jp.parse(json_String_to_print));
It can be used when you don't have the bean as in susemi99's post.
Edit: I misunderstood your question, I thought you were asking how to pad with spaces.
What you are asking is not possible using the string.Format
alignment component; string.Format
always pads with whitespace. See the Alignment Component section of MSDN: Composite Formatting.
According to Reflector, this is the code that runs inside StringBuilder.AppendFormat(IFormatProvider, string, object[])
which is called by string.Format
:
int repeatCount = num6 - str2.Length;
if (!flag && (repeatCount > 0))
{
this.Append(' ', repeatCount);
}
this.Append(str2);
if (flag && (repeatCount > 0))
{
this.Append(' ', repeatCount);
}
As you can see, blanks are hard coded to be filled with whitespace.
If you want something concise try:
for (first in obj) break;
alert(first);
wrapped as a function:
function first(obj) {
for (var a in obj) return a;
}

If your using a background resource and wish to change the resource out you can use setBackgroundResource() function.
ui_item.setBackgroundResource(R.drawable.myResource)
A background resource in XML would look like:
<LinearLayout
android:id="@+id/ui_item"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/background_01"
android:orientation="vertical">

Obviously, you'll need a rooted android device. Then set up an FTP server and transfer the files.
YES!! you can launch Device Settings screen, I have tested on iOS 9.2
Step 1. we need to add URL schemes
Go to Project settings --> Info --> URL Types --> Add New URL Schemes
Step 2. Launch Settings programmatically Thanks to @davidcann
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs://"]];
Also we can launch sub-screens like Music, Location etc. as well by just using proper name
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=MUSIC"]];
See this full name list here shared by Henri Normak
Update:
As per the comment everyone wants to know what happens after this change to my application submission status?
So YES!! I got successful update submission and application is available on store without any complain.
Just to confirm, I Just downloaded this morning and disabled Location services, and then started the app, which asked me for location permission and then my alert popup was there to send me on settings -> location services page --> Enabled --> That's it!!
![NOTICE: Your app might be rejected ... even if it's approved it can be rejected in future version if you use this method...]4
Yep, that code is completely redundant and unnecessary and it doesn't make the garbage collector do anything it wouldn't otherwise do (once an instance of MyCollection goes out of scope, that is.) Especially the .Clear()
calls.
Answer to your edit: Sort of. If I do this:
public void WasteMemory()
{
var instance = new MyCollection(); // this one has no Dispose() method
instance.FillItWithAMillionStrings();
}
// 1 million strings are in memory, but marked for reclamation by the GC
It's functionally identical to this for purposes of memory management:
public void WasteMemory()
{
var instance = new MyCollection(); // this one has your Dispose()
instance.FillItWithAMillionStrings();
instance.Dispose();
}
// 1 million strings are in memory, but marked for reclamation by the GC
If you really really really need to free the memory this very instant, call GC.Collect()
. There's no reason to do this here, though. The memory will be freed when it's needed.
Spinner don't support Hint, i recommend you to make a custom spinner adapter.
check this link : https://stackoverflow.com/a/13878692/1725748
From the performance point of view your solution is not optimal. Every time you add another log entry with +=, the whole string is copied to another place in memory. I would recommend using StringBuilder instead:
StringBuilder sb = new StringBuilder();
...
sb.Append("log something");
...
// flush every 20 seconds as you do it
File.AppendAllText(filePath+"log.txt", sb.ToString());
sb.Clear();
By the way your timer event is probably executed on another thread. So you may want to use a mutex when accessing your sb
object.
Another thing to consider is what happens to the log entries that were added within the last 20 seconds of the execution. You probably want to flush your string to the file right before the app exits.
I found this to be the shortest working way to refresh with ui-router:
$state.go($state.current, {}, {reload: true}); //second parameter is for $stateParams
Update for newer versions:
$state.reload();
Which is an alias for:
$state.transitionTo($state.current, $stateParams, {
reload: true, inherit: false, notify: true
});
Documentation: https://angular-ui.github.io/ui-router/site/#/api/ui.router.state.$state#methods_reload
This code can be used to export any file, including csv
// application/octet-stream tells the browser not to try to interpret the file
header('Content-type: application/octet-stream');
header('Content-Length: ' . filesize($data));
header('Content-Disposition: attachment; filename="export.csv"');
for first 10 rows...
SELECT * FROM msgtable WHERE cdate='18/07/2012' LIMIT 0,10
for next 10 rows
SELECT * FROM msgtable WHERE cdate='18/07/2012' LIMIT 10,10
@media print {_x000D_
a[href]:after {_x000D_
display: none;_x000D_
visibility: hidden;_x000D_

_x000D_
Work's perfect.

@Mock
private MyMock myMock;
@InjectMocks
private MyAbstractClass thiz = this;

@Override
public String getName() {
return myName;

String result = sayHello();
assertEquals("Hello, Johnny", result);
}

Repetition in regex by default is greedy: they try to match as many reps as possible, and when this doesn't work and they have to backtrack, they try to match one fewer rep at a time, until a match of the whole pattern is found. As a result, when a match finally happens, a greedy repetition would match as many reps as possible.
The ?
as a repetition quantifier changes this behavior into non-greedy, also called reluctant (in e.g. Java) (and sometimes "lazy"). In contrast, this repetition will first try to match as few reps as possible, and when this doesn't work and they have to backtrack, they start matching one more rept a time. As a result, when a match finally happens, a reluctant repetition would match as few reps as possible.
Let's compare these two patterns: A.*Z
and A.*?Z
.
Given the following input:
eeeAiiZuuuuAoooZeeee
The patterns yield the following matches:
A.*Z
yields 1 match: AiiZuuuuAoooZ
(see on rubular.com)A.*?Z
yields 2 matches: AiiZ
and AoooZ
(see on rubular.com)Let's first focus on what A.*Z
does. When it matched the first A
, the .*
, being greedy, first tries to match as many .
as possible.
eeeAiiZuuuuAoooZeeee
\_______________/
A.* matched, Z can't match
Since the Z
doesn't match, the engine backtracks, and .*
must then match one fewer .
:
eeeAiiZuuuuAoooZeeee
\______________/
A.* matched, Z still can't match
This happens a few more times, until finally we come to this:
eeeAiiZuuuuAoooZeeee
\__________/
A.* matched, Z can now match
Now Z
can match, so the overall pattern matches:
eeeAiiZuuuuAoooZeeee
\___________/
A.*Z matched
By contrast, the reluctant repetition in A.*?Z
first matches as few .
as possible, and then taking more .
as necessary. This explains why it finds two matches in the input.
Here's a visual representation of what the two patterns matched:
eeeAiiZuuuuAoooZeeee
\__/r \___/r r = reluctant
\____g____/ g = greedy
In many applications, the two matches in the above input is what is desired, thus a reluctant .*?
is used instead of the greedy .*
to prevent overmatching. For this particular pattern, however, there is a better alternative, using negated character class.
The pattern A[^Z]*Z
also finds the same two matches as the A.*?Z
pattern for the above input (as seen on ideone.com). [^Z]
is what is called a negated character class: it matches anything but Z
.
The main difference between the two patterns is in performance: being more strict, the negated character class can only match one way for a given input. It doesn't matter if you use greedy or reluctant modifier for this pattern. In fact, in some flavors, you can do even better and use what is called possessive quantifier, which doesn't backtrack at all.
This example should be illustrative: it shows how the greedy, reluctant, and negated character class patterns match differently given the same input.
eeAiiZooAuuZZeeeZZfff
These are the matches for the above input:
A[^Z]*ZZ
yields 1 match: AuuZZ
(as seen on ideone.com)A.*?ZZ
yields 1 match: AiiZooAuuZZ
(as seen on ideone.com)A.*ZZ
yields 1 match: AiiZooAuuZZeeeZZ
(as seen on ideone.com)Here's a visual representation of what they matched:
___n
/ \ n = negated character class
eeAiiZooAuuZZeeeZZfff r = reluctant
\_________/r / g = greedy
\____________/g

- Another Update -
Since Twitter Bootstrap version 2.0 - which saw the removal of the .container-fluid
class - it has not been possible to implement a two column fixed-fluid layout using just the bootstrap classes - however I have updated my answer to include some small CSS changes that can be made in your own CSS code that will make this possible
It is possible to implement a fixed-fluid structure using the CSS found below and slightly modified HTML code taken from the Twitter Bootstrap Scaffolding : layouts documentation page:
<div class="container-fluid fill">
<div class="row-fluid">
<div class="fixed"> <!-- we want this div to be fixed width -->
...
</div>
<div class="hero-unit filler"> <!-- we have removed spanX class -->
...
</div>
</div>
</div>
/* CSS for fixed-fluid layout */
.fixed {
width: 150px; /* the fixed width required */
float: left;
}
.fixed + div {
margin-left: 150px; /* must match the fixed width in the .fixed class */
overflow: hidden;
}
/* CSS to ensure sidebar and content are same height (optional) */
html, body {
height: 100%;
}
.fill {
min-height: 100%;
position: relative;
}
.filler:after{
background-color:inherit;
bottom: 0;
content: "";
height: auto;
min-height: 100%;
left: 0;
margin:inherit;
right: 0;
position: absolute;
top: 0;
width: inherit;
z-index: -1;
}
I have kept the answer below - even though the edit to support 2.0 made it a fluid-fluid solution - as it explains the concepts behind making the sidebar and content the same height (a significant part of the askers question as identified in the comments)
Update As pointed out by @JasonCapriotti in the comments, the original answer to this question (created for v1.0) did not work in Bootstrap 2.0. For this reason, I have updated the answer to support Bootstrap 2.0
To ensure that the main content fills at least 100% of the screen height, we need to set the height of the html
and body
to 100% and create a new css class called .fill
which has a minimum-height of 100%:
html, body {
height: 100%;
}
.fill {
min-height: 100%;
}
We can then add the .fill
class to any element that we need to take up 100% of the sceen height. In this case we add it to the first div:
<div class="container-fluid fill">
...
</div>
To ensure that the Sidebar and the Content columns have the same height is very difficult and unnecessary. Instead we can use the ::after
pseudo selector to add a filler
element that will give the illusion that the two columns have the same height:
.filler::after {
background-color: inherit;
bottom: 0;
content: "";
right: 0;
position: absolute;
top: 0;
width: inherit;
z-index: -1;
}
To make sure that the .filler
element is positioned relatively to the .fill
element we need to add position: relative
to .fill
:
.fill {
min-height: 100%;
position: relative;
}
And finally add the .filler
style to the HTML:
HTML
<div class="container-fluid fill">
<div class="row-fluid">
<div class="span3">
...
</div>
<div class="span9 hero-unit filler">
...
</div>
</div>
</div>

$collection = MyModel::all()->groupBy('column');
If you want to convert the collection to plain php array, you can use toArray()
$array = MyModel::all()->groupBy('column')->toArray();
SELECT *

SELECT *
FROM users
WHERE 1
ORDER BY
rand()
LIMIT 20
) q
ORDER BY

No need to use a macro. Supposing your first string is in A1.
=RIGHT(A1, 4)
Drag this down and you will get your four last characters.
Edit: To be sure, if you ever have sequences like 'ABC DEF' and want the last four LETTERS and not CHARACTERS you might want to use trimspaces()
=RIGHT(TRIMSPACES(A1), 4)
Edit: As per brettdj's suggestion, you may want to check that your string is actually 4-character long or more:
=IF(TRIMSPACES(A1)>=4, RIGHT(TRIMSPACES(A1), 4), TRIMSPACES(A1))
It's very easy.

My answer (as at Aug 2015), given Swift keeps evolving:
let version = NSBundle.mainBundle().infoDictionary!["CFBundleVersion"] as! String
You can use org.apache.commons.lang.time.DateUtils
to make it cleaner:
(firstDate.getTime() - secondDate.getTime()) / DateUtils.MILLIS_PER_SECOND
You can work around that via a Live Template. Go to Settings -> Live Template, click the "Add"-Button (green plus on the right).
In the "Abbreviation" field, enter the string that should activate the template (e.g. @a
), and in the "Template Text" area enter the string to complete (e.g. @author - My Name
). Set the "Applicable context" to Java (Comments only maybe) and set a key to complete (on the right).
I tested it and it works fine, however IntelliJ seems to prefer the inbuild templates, so "@a + Tab" only completes "author". Setting the completion key to Space worked however.
To change the user name that is automatically inserted via the File Templates (when creating a class for example), can be changed by adding
-Duser.name=Your name
to the idea.exe.vmoptions or idea64.exe.vmoptions (depending on your version) in the IntelliJ/bin directory.
Restart IntelliJ
Starting with TypeScript 2.2 using dot notation to access indexed properties is allowed. You won't get error TS2339 on your example.
See Dotted property for types with string index signatures in TypeScript 2.2 release note.
Going on the assumption you're using TNSNAMES naming, here's a couple of things to do:
> SERVICENAME_alias = > (DESCRIPTION = > (ADDRESS = (PROTOCOL = TCP)(HOST = HOST.XYZi.com)(PORT = 1521)) > (CONNECT_DATA = (SERVICE_NAME = SERVICENAME))
This is assuming you're using the standard Oracle port of 1521. Note that servicename_alias can be any name you want to use on the local system. You may also find that you need to specify (SID = SERVICENAME) instead of (SERVICENAME=SERVICENAME).
While I tried the approach above, it becomes a complete disaster with mvc. Your controller passing a model and your view using a strongly typed model become too difficult to work with.
Get your Dataset into a List ..... I have a repository pattern and here is an example of getting a dataset from an old school asmx web service private readonly CISOnlineSRVDEV.ServiceSoapClient _ServiceSoapClient;
public Get_Client_Repository()
: this(new CISOnlineSRVDEV.ServiceSoapClient())
{
}
public Get_Client_Repository(CISOnlineSRVDEV.ServiceSoapClient serviceSoapClient)
{
_ServiceSoapClient = serviceSoapClient;
}
public IEnumerable<IClient> GetClient(IClient client)
{
// **** Calling teh web service with passing in the clientId and returning a dataset
DataSet dataSet = _ServiceSoapClient.get_clients(client.RbhaId,
client.ClientId,
client.AhcccsId,
client.LastName,
client.FirstName,
"");//client.BirthDate.ToString()); //TODO: NEED TO FIX
// USE LINQ to go through the dataset to make it easily available for the Model to display on the View page
List<IClient> clients = (from c in dataSet.Tables[0].AsEnumerable()
select new Client()
{
RbhaId = c[5].ToString(),
ClientId = c[2].ToString(),
AhcccsId = c[6].ToString(),
LastName = c[0].ToString(), // Add another field called Sex M/F c[4]
FirstName = c[1].ToString(),
BirthDate = c[3].ToDateTime() //extension helper ToDateTime()
}).ToList<IClient>();
return clients;
}
Then in the Controller I'm doing this
IClient client = (IClient)TempData["Client"];
// Instantiate and instance of the repository
var repository = new Get_Client_Repository();
// Set a model object to return the dynamic list from repository method call passing in the parameter data
var model = repository.GetClient(client);
// Call the View up passing in the data from the list
return View(model);
Then in the View it is easy :
@model IEnumerable<CISOnlineMVC.DAL.IClient>
@{
ViewBag.Title = "CLIENT ALL INFORMATION";
}
<h2>CLIENT ALL INFORMATION</h2>
<table>
<tr>
<th></th>
<th>Last Name</th>
<th>First Name</th>
<th>Client ID</th>
<th>DOB</th>
<th>Gender</th>
<th>RBHA ID</th>
<th>AHCCCS ID</th>
</tr>
@foreach (var item in Model) {
<tr>
<td>
@Html.ActionLink("Select", "ClientDetails", "Cis", new { id = item.ClientId }, null) |
</td>
<td>
@item.LastName
</td>
<td>
@item.FirstName
</td>
<td>
@item.ClientId
</td>
<td>
@item.BirthDate
</td>
<td>
Gender @* ADD in*@
</td>
<td>
@item.RbhaId
</td>
<td>
@item.AhcccsId
</td>
</tr>
}
</table>
I got the error as, "svn: Commit blocked by pre-commit hook (exit code 1) with output: Failed with exception: Lost connection to MySQL server at 'reading initial communication packet', system error: 104."
I tried 'svn commit' after 'svn cleanup'. And It works fine!.
set the system property log4j.debug=true. Then you can determine where your configuration is running amuck.
Here's an old-fashioned unix trick for removing the last 3 characters from a line that makes no use of sed OR awk...
> echo 987654321 | rev | cut -c 4- | rev
987654
Unlike the earlier example using 'cut', this does not require knowledge of the line length.

I had problems with this following:
on Android Studio version: 3.3.2
until I killed the .idea/workspace.xml file.
$ cp -rv Testcopysource/ TestCopyDest
$ rm TestCopyDest/.idea/workspace.xml
$ stdio.sh & # Run Android Studio on Linux
Prior to doing that Android Studio would still point to the original source folder and all renames were applied to the original source files (within Testcopysource in my example above).
Just for the records, Java 8 provides a better alternative.

I disagree with the advice given here - even the reference for the accepted answer concludes:
You can of course use query string parameters with HTTPS, but don’t use them for anything that could present a security problem. For example, you could safely use them to identity part numbers or types of display like ‘accountview’ or ‘printpage’, but don’t use them for passwords, credit card numbers or other pieces of information that should not be publicly available.
So, no they aren't really safe...!
For completeness: Enthought has a Python distribution which includes SciPy; however, it's not free. Caveat: I've never used it.
Update: This answer had been long forgotten until an upvote brought me back to it. At this time, I'll second endolith's suggestion of Anaconda, which is free.
Seems like just adding meta tags to index.html doesn't prevent page from zooming. Adding below style will do the magic.
:root {

I had a similar error on my side when I was using JDBC in Java code.
According to this website (the second awnser) it suggest that you are trying to execute the query with a missing parameter.
For instance :
exec SomeStoredProcedureThatReturnsASite( :L_kSite );
You are trying to execute the query without the last parameter.
Maybe in SQLPlus
it doesn't have the same requirements, so it might have been a luck that it worked there.
you can get the nodejs configuration from http://nodejs.org/
The important thing you need to keep in your mind is about its configuration in file app.js which consists of port number host and other settings these are settings working for me
backendSettings = { "scheme":"https / http ", "host":"Your website url", "port":49165, //port number 'sslKeyPath': 'Path for key', 'sslCertPath': 'path for SSL certificate', 'sslCAPath': '', "resource":"/socket.io", "baseAuthPath": '/nodejs/', "publishUrl":"publish", "serviceKey":"", "backend":{ "port":443, "scheme": 'https / http', //whatever is your website scheme "host":"host name", "messagePath":"/nodejs/message/"}, "clientsCanWriteToChannels":false, "clientsCanWriteToClients":false, "extensions":"", "debug":false, "addUserToChannelUrl": 'user/channel/add/:channel/:uid', "publishMessageToContentChannelUrl": 'content/token/message', "transports":["websocket", "flashsocket", "htmlfile", "xhr-polling", "jsonp-polling"], "jsMinification":true, "jsEtag":true, "logLevel":1};
In this if you are getting "Error: listen EADDRINUSE" then please change the port number i.e, here I am using "49165" so you can use other port such as 49170 or some other port.
For this you can refer to the following article
http://www.a2hosting.com/kb/installable-applications/manual-installations/installing-node-js-on-shared-hosting-accounts
You can use PdfBox from Apache which is simple to use and has good performance.
Here is an example of extracting text from a PDF file (you can read more here) :
import java.io.*;
import org.apache.pdfbox.pdmodel.*;
import org.apache.pdfbox.util.*;
public class PDFTest {
public static void main(String[] args){
PDDocument pd;
BufferedWriter wr;
try {
File input = new File("C:\\Invoice.pdf"); // The PDF file from where you would like to extract
File output = new File("C:\\SampleText.txt"); // The text file where you are going to store the extracted data
pd = PDDocument.load(input);
System.out.println(pd.getNumberOfPages());
System.out.println(pd.isEncrypted());
pd.save("CopyOfInvoice.pdf"); // Creates a copy called "CopyOfInvoice.pdf"
PDFTextStripper stripper = new PDFTextStripper();
wr = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(output)));
stripper.writeText(pd, wr);
if (pd != null) {
pd.close();
}
// I use close() to flush the stream.
wr.close();
} catch (Exception e){
e.printStackTrace();
}
}
}
UPDATE:
You can get the text using PDFTextStripper:
PDFTextStripper reader = new PDFTextStripper();
String pageText = reader.getText(pd); // PDDocument object created
Tablets supports tvdpi and for that scaling factor is 1.33 times dimensions of medium dpi
ldpi | mdpi | tvdpi | hdpi | xhdpi | xxhdpi | xxxhdpi
0.75 | 1 | 1.33 | 1.5 | 2 | 3 | 4
This means that if you generate a 400x400 image for xxxhdpi devices, you should generate the same resource in 300x300 for xxhdpi, 200x200 for xhdpi, 133x133 for tvdpi, 150x150 for hdpi, 100x100 for mdpi, and 75x75 for ldpi devices
You will need to import the other file as a module like this:
import Math
If you don't want to prefix your Calculate
function with the module name then do this:
from Math import Calculate
If you want to import all members of a module then do this:
from Math import *
Edit: Here is a good chapter from Dive Into Python that goes a bit more in depth on this topic.
use appcmd to export one or all the sites out then reimport into the new server. It could be iis7.0 or 7.5 When you export out using appcmd, the passwords are decrypted, then reimport and they will reencrypt.
For Ubuntu (not only?):
see Sergeis Answer but instead of openssl use zlib-flate:
cat appbackup.ab | (dd bs=24 count=0 skip=1; cat) | zlib-flate -uncompress > appbackup.tar
Otherwise openssl will probably throw:
openssl:Error: 'zlib' is an invalid command.
because openssl is not compiled with zlib support in Ubuntu
I messed with this problem 2 times and tried all suggestions here with mediocre success.
First time I tried (and succeeded luckily) by:
delete the node_modules folder in your project
npm clean cache -f
check your %APPDATA%/npm-cache
and delete everything if not empty
start the terminal as administrator (in my opinion, it isnt a problem of rights, but it wont hurt if you do so)
npm install
and then npm update
you will get errors, just install every module that throws an error manually and step by step try to eliminate everything whats wrong
However, this method is quite frustrating and not working everytime. So try this:
Second time I had no luck with the steps above, so I tried to completely reinstall npm and it failed. So I thought there must something be wrong with my node.js installation. My team is running 6.10. and I had the 6.11. and tried it with the 6.10. with no luck.
So I completely wiped everything off my system. Deleted all node modules, checked every path where node or npm could be and cleaned my system.
Then I installed newest 8.1.3
Deleted my project and cloned it to a complete different directory.
Now I installed and updated everything with npm install
npm update
Then I compiled with just 2 modules missing and installed them manually
Tadaaaaa, its working now. So all in all it was a problem with node.js. I recommend to everyone who runs into this problem: Try different node versions! And clean ABSOLUTE everything.
In your case
Employee emp = (Employee)mgr; //mgr is Manager
you are doing an upcasting.
An upcast always succeeds unlike a downcast that requires an explicit cast because it can potentially fail at runtime.(InvalidCastException).
C# offers two operators to avoid this exception to be thrown:
Starting from:
Employee e = new Employee();
First:
Manager m = e as Manager; // if downcast fails m is null; no exception thrown
Second:
if (e is Manager){...} // the predicate is false if the downcast is not possible
Warning: When you do an upcast you can only access to the superclass' methods, properties etc...
You should use Ctrl+shift+enter when using the =SUM(VLOOKUP(A9,A1:D5,{2,3,4,},FALSE)) that results in {=SUM(VLOOKUP(A9,A1:D5,{2,3,4,},FALSE))} en also works.
import csv
dict = {"Key Header":"Value Header", "key1":"value1", "key2":"value2"}
with open("test.csv", "w") as f:
writer = csv.writer(f)
for i in dict:
writer.writerow([i, dict[i]])
f.close()
Try replacing %H (Hour on a 24-hour clock) with %I (Hour on a 12-hour clock) ?
Settings->Preferences->Auto-Completion and there check Enable auto-completion on each input. Press Ctrl + Space to get a autocomplete hint. For auto-complete in code type the first letter then press Ctrl + Enter. all the inputs you have given will be listed.
/proc/partitions
will list all the block devices and partitions that the system recognizes. You can then try using file -s <device>
to determine what kind of filesystem is present on the partition, if any.
You don't need a library beyond the standard one - just use Charset. (You can just use the String constructors and getBytes methods, but personally I don't like just working with the names of character encodings. Too much room for typos.)
EDIT: As pointed out in comments, you can still use Charset instances but have the ease of use of the String methods: new String(bytes, charset) and String.getBytes(charset).
See "URL Encoding (or: 'What are those "%20
" codes in URLs?')".
On CentOS Linux release 7.5.1804, we were able to make this work by editing /etc/selinux/config and changing the setting of SELINUX like so:

When using MySQL Workbench, at Data Export, click in Advanced Options and uncheck the "lock-tables" options.
To increase the phpMyAdmin
Session Timeout, open config.inc.php
in the root phpMyAdmin
directory and add this setting (anywhere).
$cfg['LoginCookieValidity'] = <your_new_timeout>;
Where <your_new_timeout>
is some number larger than 1800.
Note:
Always keep on mind that a short cookie lifetime is all well and good for the development server. So do not do this on your production server.
Try this:

`updated_at` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
) ENGINE = INNODB;
A memory heap is a common structure for holding dynamically allocated memory. See Dynamic_memory_allocation on wikipedia.
There are other structures, like pools, stacks and piles.
While Docker for Windows is perfectly able to run Linux containers, the converse, while theoretically possible, is not implemented due to practical reasons.
The most obvious one is, while Docker for Windows can run a Linux VM freely, Docker for Linux would require a Windows license in order to run it inside a VM.
Also, Linux is completely customizable, so the Linux VM used by Docker for Windows has been stripped down to just a few MB, containing only the bare minimum needed to run the containers, while the smallest Windows distribution available is about 1.5 GB. It may not be an impracticable size, but it is much more cumbersome than the Linux on Windows counterpart.
While it is certainly possible for someone to sell a Docker for Linux variation bundled with a Windows license and ready to run Windows containers under Linux (and I don't know if such product exists), the bottom line is that you can't avoid paying Windows vendor lock-in price: both in money and storage space.
Thank you WiredPrairie!
Just to expand on your answer a bit, here is a complete example of defining a constants class.
// CYConstants.ts
class CYConstants {
public static get NOT_FOUND(): number { return -1; }
public static get EMPTY_STRING(): string { return ""; }
}
export = CYConstants;
To use
// main.ts
import CYConstants = require("./CYConstants");
console.log(CYConstants.NOT_FOUND); // Prints -1
console.log(CYConstants.EMPTY_STRING); // Prints "" (Nothing!)
Very much agreed with @Patrik M, but the thing with Arrays.toString is that it includes "[" and "]" and "," in the output. So I'll simply use a regex to remove them from outout like this
String strOfInts = Arrays.toString(intArray).replaceAll("\\[|\\]|,|\\s", "");
and now you have a String which can be parsed back to java.lang.Number
, for example,
long veryLongNumber = Long.parseLong(intStr);
Or you can use the java 8 streams, if you hate regex,
String strOfInts = Arrays
.stream(intArray)
.mapToObj(String::valueOf)
.reduce((a, b) -> a.concat(",").concat(b))
.get();
Some of these answers seem unnecessarily complex. Make your tbody:
display: block; height: 300px; overflow-y: auto
Then manually set the widths of each column so that the thead and tbody columns are the same width. Setting the table's style="table-layout: fixed" may also be necessary.
Just to mention that once you excluded the files from Sonar, do the same for Jacoco plugin:
<configuration>
<excludes>
<exclude>com/acme/model/persistence/entity/TransactionEntity*</exclude>
<exclude>com/acme/model/persistence/ModelConstants.class</exclude>
</excludes>
</configuration>
We can also use SQL kind of expression inside filter :
Note -> Here I am showing two conditions and a date range for future reference :
ordersDf.filter("order_status = 'PENDING_PAYMENT' AND order_date BETWEEN '2013-07-01' AND '2013-07-31' ")
An alternative, using plain Java 7 classes and varargs: create a class HashMapBuilder
with this method:
public static HashMap<String, String> build(String... data){
HashMap<String, String> result = new HashMap<String, String>();
if(data.length % 2 != 0)
throw new IllegalArgumentException("Odd number of arguments");
String key = null;
Integer step = -1;
for(String value : data){
step++;
switch(step % 2){
case 0:
if(value == null)
throw new IllegalArgumentException("Null key value");
key = value;
continue;
case 1:
result.put(key, value);
break;
}
}
return result;
}
Use the method like this:
HashMap<String,String> data = HashMapBuilder.build("key1","value1","key2","value2");
Also have a look at Microsoft's Compatibility Inspector, which will give you warnings of issues that will affect your sites backwards compatibility.
For those who would like to use #pragma once and include guards together: If you are not using MSVC, then you won't get much optimization from #pragma once.
And you shouldn't put "#pragma once" into a header that supposed to be included multiple times with each inclusion possibly having a different effect.
Here is a detailed discussion with examples about #pragma once usage.
Looping through all the files in the folder is relatively easy:
files = dir('*.csv');

I had a similar issue and solved it with a patch to ec2.py and adding some configuration parameters to ec2.ini. The patch takes the value of ec2_key_name, prefixes it with the ssh_key_path, and adds the ssh_key_suffix to the end, and writes out ansible_ssh_private_key_file as this value.
The following variables have to be added to ec2.ini in a new 'ssh' section (this is optional if the defaults match your environment):
[ssh]
# Set the path and suffix for the ssh keys
ssh_key_path = ~/.ssh
ssh_key_suffix = .pem
Here is the patch for ec2.py:
204a205,206
> 'ssh_key_path': '~/.ssh',
> 'ssh_key_suffix': '.pem',
422a425,428
> # SSH key setup
> self.ssh_key_path = os.path.expanduser(config.get('ssh', 'ssh_key_path'))
> self.ssh_key_suffix = config.get('ssh', 'ssh_key_suffix')
>
1490a1497
> instance_vars["ansible_ssh_private_key_file"] = os.path.join(self.ssh_key_path, instance_vars["ec2_key_name"] + self.ssh_key_suffix)
The DictWriter()
class expects dictionaries for each row. If all you wanted to do was write an initial header, use a regular csv.writer()
and pass in a simple row for the header:
import csv
with open('combined_file.csv', 'w', newline='') as outcsv:
writer = csv.writer(outcsv)
writer.writerow(["Date", "temperature 1", "Temperature 2"])
with open('t1.csv', 'r', newline='') as incsv:
reader = csv.reader(incsv)
writer.writerows(row + [0.0] for row in reader)
with open('t2.csv', 'r', newline='') as incsv:
reader = csv.reader(incsv)
writer.writerows(row[:1] + [0.0] + row[1:] for row in reader)
The alternative would be to generate dictionaries when copying across your data:
import csv
with open('combined_file.csv', 'w', newline='') as outcsv:
writer = csv.DictWriter(outcsv, fieldnames = ["Date", "temperature 1", "Temperature 2"])
writer.writeheader()
with open('t1.csv', 'r', newline='') as incsv:
reader = csv.reader(incsv)
writer.writerows({'Date': row[0], 'temperature 1': row[1], 'temperature 2': 0.0} for row in reader)
with open('t2.csv', 'r', newline='') as incsv:
reader = csv.reader(incsv)
writer.writerows({'Date': row[0], 'temperature 1': 0.0, 'temperature 2': row[1]} for row in reader)
Inorder to find an app's name (application label), you need to do the following:
(as shown in other answers)
aapt
command, find the app label.But devices don't ship with the aapt
binary out-of-the-box.
So you will need to install it first. You can download it from here:
https://github.com/Calsign/APDE/tree/master/APDE/src/main/assets/aapt-binaries
Check this guide for complete steps:

Similar to what StuartLC was saying, my problem was not resolved until I enabled TCP/IP protocol under SQL Network Configuration>>Protocols for MSSQLSERVER in the SQL Server Configuration Manager dialogue box. After enabling this and a restart, my SSMS connected right away with just the instance name (no ~\MSSQLSERVER).
You might be able to make use of sql.js.
sql.js is a port of SQLite to JavaScript, by compiling the SQLite C code with Emscripten. no C bindings or node-gyp compilation here.
<script src='js/sql.js'></script>
<script>
//Create the database
var db = new SQL.Database();
// Run a query without reading the results
db.run("CREATE TABLE test (col1, col2);");
// Insert two rows: (1,111) and (2,222)
db.run("INSERT INTO test VALUES (?,?), (?,?)", [1,111,2,222]);
// Prepare a statement
var stmt = db.prepare("SELECT * FROM test WHERE col1 BETWEEN $start AND $end");
stmt.getAsObject({$start:1, $end:1}); // {col1:1, col2:111}
// Bind new values
stmt.bind({$start:1, $end:2});
while(stmt.step()) { //
var row = stmt.getAsObject();
// [...] do something with the row of result
}
</script>
sql.js
is a single JavaScript file and is about 1.5MiB in size currently. While this could be a problem in a web-page, the size is probably acceptable for an extension.
Easiest way: You should create a new emulator, before opening it for the first time follow these 3 easy steps:
1- go to C:\Users[user].android\avd[your virtual device folder] open "config.ini" with text editor like notepad
2- change
"PlayStore.enabled=false" to "PlayStore.enabled=true"
3- change
mage.sysdir.1 = system-images\android-30\google_apis\x86\
to
image.sysdir.1 = system-images\android-30\google_apis_playstore\x86\
Per your pastebin, you need to add the proxy.tkk.com
certificate to the truststore.
Do something like this:
if($request->hasFile('video')){
$video=$request->file('video');
$filename=str_random(20).".".$video->extension();
$path = Storage::putFileAs(
'/', $video, $filename
);
$data['video']=$filename;
}
String url = "http://test.com/Services/rest/{id}/Identifier";
Map<String, String> params = new HashMap<String, String>();
params.put("id", "1234");
URI uri = UriComponentsBuilder.fromUriString(url)
.buildAndExpand(params)
.toUri();
uri = UriComponentsBuilder
.fromUri(uri)
.queryParam("name", "myName")
.build()
.toUri();
restTemplate.exchange(uri , HttpMethod.PUT, requestEntity, class_p);
The safe way is to expand the path variables first, and then add the query parameters:
For me this resulted in duplicated encoding, e.g. a space was decoded to %2520 (space -> %20 -> %25).
I solved it by:
String url = "http://test.com/Services/rest/{id}/Identifier";
Map<String, String> params = new HashMap<String, String>();
params.put("id", "1234");
UriComponentsBuilder uriComponentsBuilder = UriComponentsBuilder.fromUriString(url);
uriComponentsBuilder.uriVariables(params);
Uri uri = uriComponentsBuilder.queryParam("name", "myName");
.build()
.toUri();
restTemplate.exchange(uri , HttpMethod.PUT, requestEntity, class_p);
Essentially I am using uriComponentsBuilder.uriVariables(params);
to add path parameters. The documentation says:
... In contrast to UriComponents.expand(Map) or buildAndExpand(Map), this method is useful when you need to supply URI variables without building the UriComponents instance just yet, or perhaps pre-expand some shared default values such as host and port. ...
This is happening because there is no package cache in the image, you need to run:
apt-get -qq update
before installing packages, and if your command is in a Dockerfile, you'll then need:
apt-get -qq -y install curl
After that install ZSH and GIT Core:
apt-get install zsh
apt-get install git-core
Getting zsh
to work in ubuntu is weird since sh
does not understand the source command. So, you do this to install zsh
:
wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh
and then you change your shell to zsh:
chsh -s `which zsh`
and then restart:
sudo shutdown -r 0
This problem is explained in depth in this issue.
I figured it out. Basically it's an async issue. You can't just submit and expect to render the subsequent page immediately. You have to wait until the onLoad event for the next page is triggered. My code is below:
var page = new WebPage(), testindex = 0, loadInProgress = false;
page.onConsoleMessage = function(msg) {
console.log(msg);
};
page.onLoadStarted = function() {
loadInProgress = true;
console.log("load started");
};
page.onLoadFinished = function() {
loadInProgress = false;
console.log("load finished");
};
var steps = [
function() {
//Load Login Page
page.open("https://website.com/theformpage/");
},
function() {
//Enter Credentials
page.evaluate(function() {
var arr = document.getElementsByClassName("login-form");
var i;
for (i=0; i < arr.length; i++) {
if (arr[i].getAttribute('method') == "POST") {
arr[i].elements["email"].value="mylogin";
arr[i].elements["password"].value="mypassword";
return;
}
}
});
},
function() {
//Login
page.evaluate(function() {
var arr = document.getElementsByClassName("login-form");
var i;
for (i=0; i < arr.length; i++) {
if (arr[i].getAttribute('method') == "POST") {
arr[i].submit();
return;
}
}
});
},
function() {
// Output content of page to stdout after form has been submitted
page.evaluate(function() {
console.log(document.querySelectorAll('html')[0].outerHTML);
});
}
];
interval = setInterval(function() {
if (!loadInProgress && typeof steps[testindex] == "function") {
console.log("step " + (testindex + 1));
steps[testindex]();
testindex++;
}
if (typeof steps[testindex] != "function") {
console.log("test complete!");
phantom.exit();
}
}, 50);
You have two options. First one is very easy use Remove
method it is quite effective. Second way is to use ToString
with start index and end index (MSDN documentation)
Merge - HEAD branch will generate a new commit, preserving the ancestry of each commit history. History can become polluted if merge commits are made by multiple people who work on the same branch in parallel.
Rebase - Re-writes the changes of one branch onto another without creating a new commit. The code history is simplified, linear and readable but it doesn't work with pull requests, because you can't see what minor changes someone made.
I would use git merge
when dealing with feature-based workflow or if I am not familiar with rebase. But, if I want a more a clean, linear history then git rebase
is more appropriate. For more details be sure to check out this merge or rebase article.
This would work
setInterval(function(){$("#myButtonId").click();}, 1000);
I stumbled across this question to my self and I feel that a forked stream has some use cases that could prove valid. I wrote the code below as a consumer so that it does not do anything but you could apply it to functions and anything else you might come across.
class PredicateSplitterConsumer<T> implements Consumer<T>
{
private Predicate<T> predicate;
private Consumer<T> positiveConsumer;
private Consumer<T> negativeConsumer;
public PredicateSplitterConsumer(Predicate<T> predicate, Consumer<T> positive, Consumer<T> negative)
{
this.predicate = predicate;
this.positiveConsumer = positive;
this.negativeConsumer = negative;
}
@Override
public void accept(T t)
{
if (predicate.test(t))
{
positiveConsumer.accept(t);
}
else
{
negativeConsumer.accept(t);
}
}
}
Now your code implementation could be something like this:
personsArray.forEach(
new PredicateSplitterConsumer<>(
person -> person.getDateOfBirth().isPresent(),
person -> System.out.println(person.getName()),
person -> System.out.println(person.getName() + " does not have Date of birth")));
1- install exuberant ctags. If you're using osx, this article shows a little trick: http://www.runtime-era.com/2012/05/exuberant-ctags-in-osx-107.html
2- If you only wish to include the ctags for the files in your directory only, run this command in your directory:
ctags -R
This will create a "tags" file for you.
3- If you're using Ruby and wish to include the ctags for your gems (this has been really helpful for me with RubyMotion and local gems that I have developed), do the following:
ctags --exclude=.git --exclude='*.log' -R * `bundle show --paths`
credit: https://coderwall.com/p/lv1qww (Note that I omitted the -e option which generates tags for emacs instead of vim)
4- Add the following line to your ~/.vimrc
set autochdir
set tags+=./tags;
(Why the semi colon: http://vim.wikia.com/wiki/Single_tags_file_for_a_source_tree )
5- Go to the word you'd like to follow and hit ctrl + ]
; if you'd like to go back, use ctrl+o

I agree with Jim Blizard. The database is not the part of your technology stack that should send emails. For example, what if you send an email but then roll back the change that triggered that email? You can't take the email back.
It's better to send the email in your application code layer, after your app has confirmed that the SQL change was made successfully and committed.
Direct to your ViewController again. in my situation [self.view setNeedsDisplay];
and [self viewDidLoad]; [self viewWillAppear:YES];
does not work, but the method below worked.
In objective C
UIStoryboard *MyStoryboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil ];
UIViewController *vc = [MyStoryboard instantiateViewControllerWithIdentifier:@"ViewControllerStoryBoardID"];
[self presentViewController:vc animated:YES completion:nil];
Swift:
let secondViewController = self.storyboard!.instantiateViewControllerWithIdentifier("ViewControllerStoryBoardID")
self.presentViewController(secondViewController, animated: true, completion: nil)
or if you develop on localhost (only for apache 2.4+):
<If "%{REMOTE_ADDR} != '127.0.0.1'">
</If>
With Java 7 or above you could use
ThreadLocalRandom.current().nextInt(int origin, int bound)

Copying the ".txt" file from one folder to another is very simple and question contains the logic. Only missing part is substituting with right information as below:
import os, shutil, glob
src_fldr = r"Source Folder/Directory path"; ## Edit this
dst_fldr = "Destiantion Folder/Directory path"; ## Edit this
try:
os.makedirs(dst_fldr); ## it creates the destination folder
except:
print "Folder already exist or some error";
below lines of code will copy the file with *.txt extension files from src_fldr to dst_fldr
for txt_file in glob.glob(src_fldr+"\\*.txt"):
shutil.copy2(txt_file, dst_fldr);
Answer with post
is incorrect, because the size might not be recalculated.
Another important thing is that the view and all it ancestors must be visible. For that I use a property View.isShown
.
Here is my kotlin function, that can be placed somewhere in utils:
fun View.onInitialized(onInit: () -> Unit) {
viewTreeObserver.addOnGlobalLayoutListener(object : OnGlobalLayoutListener {
override fun onGlobalLayout() {
if (isShown) {
viewTreeObserver.removeOnGlobalLayoutListener(this)
onInit()
}
}
})
}
And the usage is:
myView.onInitialized {
Log.d(TAG, "width is: " + myView.width)
}
I have had the same problem with a specific package in R and the solution was I should install in the ubuntu terminal libcurl. Look at the information that appears above explaining to us that curl package has error installation.
I knew this about the message:
Configuration failed because libcurl was not found. Try installing:
* deb: libcurl4-openssl-dev (Debian, Ubuntu, etc)
* rpm: libcurl-devel (Fedora, CentOS, RHEL)
* csw: libcurl_dev (Solaris)
If libcurl is already installed, check that 'pkg-config' is in your
PATH and PKG_CONFIG_PATH contains a libcurl.pc file. If pkg-config
is unavailable you can set INCLUDE_DIR and LIB_DIR manually via:
R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'
To install it I used the net command:
sudo apt-get install libcurl4-openssl-dev
Sometimes we can not install a specific package in R because we have problems with packages that must be installed previously as curl package. To know if we should install it we should check the warning errors such as: installation of package ‘curl’ had non-zero exit status.
I hope I have been helpful
Did you read clang
documentation ? You're probably looking for -emit-llvm
.
ProjectCodeMeter counts LLOC (logical lines of code) exactly as you described (only effective lines). it integrates into eclipse as external code metrics tool, it's not real-time though, it generates a report.actually it counts many source code metrics such as complexity, arithmetic intricacy, hard coded strings, numeric constants.. even estimates development time in hours.
The answers above are perfectly valid, but a vectorized solution exists, in the form of numpy.select
. This allows you to define conditions, then define outputs for those conditions, much more efficiently than using apply
:
First, define conditions:
conditions = [
df['eri_hispanic'] == 1,
df[['eri_afr_amer', 'eri_asian', 'eri_hawaiian', 'eri_nat_amer', 'eri_white']].sum(1).gt(1),
df['eri_nat_amer'] == 1,
df['eri_asian'] == 1,
df['eri_afr_amer'] == 1,
df['eri_hawaiian'] == 1,
df['eri_white'] == 1,
]
Now, define the corresponding outputs:
outputs = [
'Hispanic', 'Two Or More', 'A/I AK Native', 'Asian', 'Black/AA', 'Haw/Pac Isl.', 'White'
]
Finally, using numpy.select
:
res = np.select(conditions, outputs, 'Other')
pd.Series(res)
0 White
1 Hispanic
2 White
3 White
4 Other
5 White
6 Two Or More
7 White
8 Haw/Pac Isl.
9 White
dtype: object
Why should numpy.select
be used over apply
? Here are some performance checks:
df = pd.concat([df]*1000)
In [42]: %timeit df.apply(lambda row: label_race(row), axis=1)
1.07 s ± 4.16 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)
In [44]: %%timeit
...: conditions = [
...: df['eri_hispanic'] == 1,
...: df[['eri_afr_amer', 'eri_asian', 'eri_hawaiian', 'eri_nat_amer', 'eri_white']].sum(1).gt(1),
...: df['eri_nat_amer'] == 1,
...: df['eri_asian'] == 1,
...: df['eri_afr_amer'] == 1,
...: df['eri_hawaiian'] == 1,
...: df['eri_white'] == 1,
...: ]
...:
...: outputs = [
...: 'Hispanic', 'Two Or More', 'A/I AK Native', 'Asian', 'Black/AA', 'Haw/Pac Isl.', 'White'
...: ]
...:
...: np.select(conditions, outputs, 'Other')
...:
...:
3.09 ms ± 17 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
Using numpy.select
gives us vastly improved performance, and the discrepancy will only increase as the data grows.
No, how you are doing it is correct.
http://www.w3.org/MarkUp/html-spec/html-spec_8.html#SEC8.2.2
you are going to want to separate your arguments into separate parameter
$msbuild = "C:\WINDOWS\Microsoft.NET\Framework\v3.5\MSBuild.exe"
$arguments = "/v:q /nologo"
start-process $msbuild $arguments
Are you sure the Start
method returns before the child process starts? I was always under the impression that Start
starts the child process synchronously.
If you want to wait until your child process finishes some sort of initialization then you need inter-process communication - see Interprocess communication for Windows in C# (.NET 2.0).
I have written a generic caching func()
which will cache any variable easily and very readable format.
Caching function:
function calculateSomethingMaybe(args){
return args;
}
function caching(fn){
const cache = {};
return function(){
const string = arguments[0];
if(!cache[string]){
const result = fn.apply(this, arguments);
cache[string] = result;
return result;
}
return cache[string];
}
}
const letsCache = caching(calculateSomethingMaybe);
console.log(letsCache('a book'), letsCache('a pen'), letsCache('a book'));
Change the submit button to:

Unless you have some really compelling reason not to, I suggest ditching the MS JDBC driver.
Instead, use the jtds jdbc driver. Read the README.SSO file in the jtds distribution on how to configure for single-sign-on (native authentication) and where to put the native DLL to ensure it can be loaded by the JVM.
You may need to check two things.
1- Database Foleder's permission The database you wants to delete must have the same owner as mysql process has.
2- Directory Must be empty Goto the mysql data directory and verify that directory is empty
After that connect your mysql cli and run drop database command again.
When you use a web service you have a client and a server:
When you use a message queue like RabbitMQ, Beanstalkd, ActiveMQ, IBM MQ Series, Tuxedo you expect different and more fault tolerant results:
Message Queues has a lot more features but this is some rule of thumb to decide if you want to handle error conditions yourself or leave them to the message queue.
This is how I resolved this problem.
In my case: I had to configure the datasource for MySQL Server, which was an external Server.
As we all know, Spring boot has capability to auto-configure DataSource for embedded databases.
Thus, I realized that I had to disable datasource auto-configuration in order use my custom configuration.
As mentioned above by many, I disabled Automatic DataSource configuration of Spring Boot at application.properties
spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration
I defined all hibernate configuration properties in a separate file: hibernate-mysql.properties
Then, I coded my own Custom Hibernate Configuration in following manner and it resolved the issue.
My way to configure the desired DataSource based on properties in a custom property file and populate your LocalSessionFactoryBean with your data source and other hibernate configuration.

You can encapsulate this quite nicely in a func similar to what is below.
package main
import (
"bufio"
"fmt"
"os"
)
func main() {
fmt.Println(prompt())
}
func prompt(params ...string) string {
prompt := ": "
if len(params) > 0 {
prompt = params[0]
}
reader := bufio.NewReader(os.Stdin)
fmt.Print(prompt)
text, _ := reader.ReadString('\n')
return text
}
In this example, the prompt by default has a colon and a space in front of it . . .
:
. . . however you can override that by supplying a parameter to the prompt function.
prompt("Input here -> ")
This will result in a prompt like below.
Input here ->
If you have another file in same directory, you can either do:
bash another_script.sh
or
source another_script.sh
or
. another_script.sh
When you use bash
instead of source
, the script cannot alter environment of the parent script. The .
command is POSIX standard while source
command is a more readable bash synonym for .
(I prefer source
over .
). If your script resides elsewhere just provide path to that script. Both relative as well as full path should work.
You could use Map to make higher abstraction on instance of
private final Map<Class, Consumer<String>> actions = new HashMap<>();
Then having such map add some action to it:
actions.put(String.class, new Consumer<String>() {
@Override
public void accept(String s) {
System.out.println("action for String");
}
};
Then having an Object of not known type you could get specific action from that map:
actions.get(someObject).accept(someObject)
I just had this same problem:
That fixed it for me
Add Custom Font in Swift
myLabel.font = UIFont (name: "GILLSANSCE-ROMAN", size: 20)
I've had success using TriadMixing and CIE94 to avoid similar colors. The following image uses input colors red, yellow, and white. See here.
I found this works more easily than getting an index. For my needs, I am selecting a tab based off a url hash
var target = window.location.hash.replace(/#/,'#tab-');
if (target) {
jQuery('a[href='+target+']').click().parent().trigger('keydown');
}
try this ...
$("#txtAreaID").bind("keyup", function(event, ui) {
// Write your code here
});
Just wanted to point out something about the solution said above several times:
git config credential.helper store
You can use any command that requires a password after this. You don't have to push. (you can also pull for instance) After that, you won't need to type in your username / password again.
If you look into CREATE PROCEDURE Syntax for latest MySQL version you'll see that procedure parameter can only contain IN/OUT/INOUT specifier, parameter name and type.
So, default values are still unavailable in latest MySQL version.
How about storing the new options
in a variable
, and then using .html(variable)
to replace the data in the container
?
I think it is so it can keep consistency with the available options used when settings multiple css styles in one function call through the use of an object, for example...
$(".element").css( { marginLeft : "200px", marginRight : "200px" } );
as you can see the property are not specified as strings. JQuery also supports using string if you still wanted to use the dash, or for properties that perhaps cannot be set without the dash, so the following still works...
$(".element").css( { "margin-left" : "200px", "margin-right" : "200px" } );
without the quotes here, the javascript would not parse correctly as property names cannot have a dash in them.
EDIT: It would appear that JQuery is not actually making the distinction itsleft, instead it is just passing the property specified for the DOM to care about, most likely with style[propertyName];
Your code compiles just fine. However, your array initialization line is wrong:
int array[]={};
What this does is declare an array with a size equal to the number of elements in the brackets. Since there is nothing in the brackets, you're saying the size of the array is 0 - this renders the array completely useless, since now it can't store anything.
Instead, you can either initialize the array right in your original line:
int array[] = { 5, 5, 5, 5 };
Or you can declare the size and then populate it:
int array[] = new int[4];
// ...while loop
If you don't know the size of the array ahead of time (for example, if you're reading a file and storing the contents), you should use an ArrayList
instead, because that's an array that grows in size dynamically as more elements are added to it (in layman's terms).
You don't have to call the external basename
command. Instead, you could use the following commands:
$ s=/the/path/foo.txt
$ echo "${s##*/}"
foo.txt
$ s=${s##*/}
$ echo "${s%.txt}"
foo
$ echo "${s%.*}"
foo
Note that this solution should work in all recent (post 2004) POSIX compliant shells, (e.g. bash
, dash
, ksh
, etc.).

It is probably more idiomatic jQuery to use the statusCode property of the parameter object passed to the the $.ajax function:
$.ajax({
statusCode: {
500: function(xhr) {
if(window.console) console.log(xhr.responseText);
}
}
});
However, as Livingston Samuel said, it is not possible to catch 301 status codes in javascript.

This is C#, but should give you the idea:
public static void Main() {
typeof(Program).GetProperty("GetMe", BindingFlags.NonPublic | BindingFlags.Static);
}
private static int GetMe {
get { return 0; }

(you need to OR NonPublic and Static only)
printDiv(divId): A generalized solution to print any div on any page.
I had a similar issue but I wanted (a) to be able to print the whole page, or (b) print any one of several specific areas. My solution, thanks to much of the above, allows you to specify any div object to be printed.
The key for this solution is to add an appropriate rule to the the print media style sheet so that the requested div (and its contents) will be printed.
First, create the needed print css to suppress everything (but without the specific rule to allow the element you want to print).
<style type="text/css" media="print">
body {visibility:hidden; }
.noprintarea {visibility:hidden; display:none}
.noprintcontent { visibility:hidden; }
.print { visibility:visible; display:block; }
</style>
Note that I have added new class rules:
Then insert three JavaScript functions. The first merely toggles the print media style sheet on and off.
function disableSheet(thisSheet,setDisabled)
{ document.styleSheets[thisSheet].disabled=setDisabled; }
The second does the real work and the third cleans up afterward. The second (printDiv) activates the print media style sheet, then appends a new rule to allow the desired div to print, issues the print, and then adds a delay before the final housekeeping (otherwise the styles can be reset before the print is actually done.)
function printDiv(divId)
{
// Enable the print CSS: (this temporarily disables being able to print the whole page)
disableSheet(0,false);
// Get the print style sheet and add a new rule for this div
var sheetObj=document.styleSheets[0];
var showDivCSS="visibility:visible;display:block;position:absolute;top:30px;left:30px;";
if (sheetObj.rules) { sheetObj.addRule("#"+divId,showDivCSS); }
else { sheetObj.insertRule("#"+divId+"{"+showDivCSS+"}",sheetObj.cssRules.length); }
print();
// need a brief delay or the whole page will print
setTimeout("printDivRestore()",100);
}
The final functions deletes the added rule and sets the print style again to disabled so the whole page can be printed.
function printDivRestore()
{
// remove the div-specific rule
var sheetObj=document.styleSheets[0];
if (sheetObj.rules) { sheetObj.removeRule(sheetObj.rules.length-1); }
else { sheetObj.deleteRule(sheetObj.cssRules.length-1); }
// and re-enable whole page printing
disableSheet(0,true);
}
The only other thing to do is to add one line to your onload processing so that the print style is initially disabled thereby allowing whole page printing.
<body onLoad='disableSheet(0,true)'>
Then, from anywhere in your document, you can print a div. Just issue printDiv("thedivid") from a button or whatever.
A big plus for this approach it provides a general solution to printing selected content from within a page. It also allows use of existing styles for elements that are printed - including the containing div.
NOTE: In my implementation, this must be the first style sheet. Change the sheet references (0) to the appropriate sheet number if you need to make it later in the sheet sequence.
<script type="text/javascript">
$(document).ready(function() {
$("#Button1").click(function() {
alert("hello");
});
}
);
</script>
My guess is the best you can come up with is
this.approved_by = IsNullOrEmpty(planRec.approved_by) ? string.Empty
: planRec.approved_by.ToString();
Of course since you're hinting at the fact that approved_by
is an object
(which cannot equal ""), this would be rewritten as
this.approved_by = (planRec.approved_by ?? string.Empty).ToString();

Construct both separate queries and joins, then time each of them -- nothing helps more than real-world numbers.
Then even better -- add "EXPLAIN" to the beginning of each query. This will tell you how many subqueries MySQL is using to answer your request for data, and how many rows scanned for each query.
My answer is an amalgamation of the above two with extension to drawing sphere of user-defined opacity and some annotation. It finds application in b-vector visualization on a sphere for magnetic resonance image (MRI). Hope you find it useful:
from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
import numpy as np
fig = plt.figure()
ax = fig.gca(projection='3d')
# draw sphere
u, v = np.mgrid[0:2*np.pi:50j, 0:np.pi:50j]
x = np.cos(u)*np.sin(v)
y = np.sin(u)*np.sin(v)
z = np.cos(v)
# alpha controls opacity
ax.plot_surface(x, y, z, color="g", alpha=0.3)
# a random array of 3D coordinates in [-1,1]
bvecs= np.random.randn(20,3)
# tails of the arrows
tails= np.zeros(len(bvecs))
# heads of the arrows with adjusted arrow head length
ax.quiver(tails,tails,tails,bvecs[:,0], bvecs[:,1], bvecs[:,2],
length=1.0, normalize=True, color='r', arrow_length_ratio=0.15)
ax.set_xlabel('X-axis')

Jeff Bridgman is correct. All you need is
background: url('pic.jpg')
and this assumes that pic is in the same folder as your html.
Also, Roberto's answer works fine. Tested in Firefox, and IE. Thanks to Raptor for adding formatting that displays full picture fit to screen, and without scrollbars... In a folder f, on the desktop is this html and a picture, pic.jpg, using your userid. Make those substitutions in the below:
<html>
<head>
<style>
body {
background: url('file:///C:/Users/userid/desktop/f/pic.jpg') no-repeat center center fixed;
background-size: cover; /* for IE9+, Safari 4.1+, Chrome 3.0+, Firefox 3.6+ */
-webkit-background-size: cover; /* for Safari 3.0 - 4.0 , Chrome 1.0 - 3.0 */
-moz-background-size: cover; /* optional for Firefox 3.6 */
-o-background-size: cover; /* for Opera 9.5 */
margin: 0; /* to remove the default white margin of body */
padding: 0; /* to remove the default white margin of body */
overflow: hidden;
}
</style>
</head>

Wouldn't the compiler cache .length, and therefore it makes no difference if you are comparing 0 or .length? I guess this is very specific to the compiler or interpreter you are dealing with.
I would say if you are using a well optimised compiler or interpreter then you shouldn't worry about this, it is for the language developers to worry about.

I used lobos answer and it works. But I had a problem with the conversion of doubles because of the culture settings. So I added
return (T)Convert.ChangeType(base.Value, typeof(T), CultureInfo.InvariantCulture);
>>> source_list = ('1','a'),('2','b'),('3','c'),('4','d')
>>> list1, list2 = zip(*source_list)
>>> list1
('1', '2', '3', '4')
>>> list2
('a', 'b', 'c', 'd')
Edit: Note that zip(*iterable)
is its own inverse:
>>> list(source_list) == zip(*zip(*source_list))
True
When unpacking into two lists, this becomes:
>>> list1, list2 = zip(*source_list)
>>> list(source_list) == zip(list1, list2)
True
Addition suggested by rocksportrocker.
You can also open a required file through a prompt, This helps when you want to select file from different path and different file.

This will fix it for a UITableViewController (without any magic numbers). The only thing I couldn't get it to fix is if you are on a phone call, in which case the top of the tableView is pushed down too much. If anyone knows how to solve that, please let us know.
class MyTableViewController: UITableViewController {
override func viewDidLoad() {
super.viewDidLoad()
configureTableViewTop()

I had exactly this problem a couple of months ago while working on a WYSIWYG email editor for my company. Outlook only supports background images if they're applied to the <body>
tag - any other element and it'll fail.
In the end, the only workaround I found was to use <div>
element for text input, then during the content submission process I fired an AJAX request with the <div>
's content to a PHP script which wrote the text onto a blank version of our header image, saved the file and returned its (uniquely generated) name. I then used Javascript to remove the <div>
and add an <img>
tag using the returned filename in the src
attribute.
You can get all the info/methodology from the imagecreatefrompng()
page on the PHP Docs site.
As you said, Safari sends Cache-Control: max-age=0
on reload. Express (or more specifically, Express's dependency, node-fresh) considers the cache stale when Cache-Control: no-cache
headers are received, but it doesn't do the same for Cache-Control: max-age=0
. From what I can tell, it probably should. But I'm not an expert on caching.
The fix is to change (what is currently) line 37 of node-fresh/index.js
from
if (cc && cc.indexOf('no-cache') !== -1) return false;
to
if (cc && (cc.indexOf('no-cache') !== -1 ||
cc.indexOf('max-age=0') !== -1)) return false;
I forked node-fresh and express to include this fix in my project's package.json
via npm
, you could do the same. Here are my forks, for example:
https://github.com/stratusdata/node-fresh https://github.com/stratusdata/express#safari-reload-fix
The safari-reload-fix branch is based on the 3.4.7 tag.

And your follow-up questions:
Q. I would like to use a font such as "Bumble bee," for example. How can I use
@font-face
to make that font available on the user's computer?
Note that I don't know what the name of your Bumble Bee font or file is, so adjust accordingly, and that the font-face declaration should precede (come before) your use of it, as I've shown above.
Q. Can I still use the other
@font-face
typeface "GestaRegular" as well? Can I use both in the same stylesheet?
Just list them together as I've shown in my example. There is no reason you can't declare both. All that @font-face
does is instruct the browser to download and make a font-family available. See: http://iliadraznin.com/2009/07/css3-font-face-multiple-weights

Here is a simple approach:
#!/bin/bash
USE_IP='-o StrictHostKeyChecking=no [email protected]'
FILE_NAME=/home/user/file.txt
SSH_PASS='sshpass -p password-for-remote-machine'
if $SSH_PASS ssh $USE_IP stat $FILE_NAME \> /dev/null 2\>\&1
then
echo "File exists"
else
echo "File does not exist"
fi
You need to install sshpass on your machine to work it.
Building off of @Gavin's answer:
Making lazygit a function instead of an alias allows you to pass it an argument. I have added the following to my .bashrc (or .bash_profile if Mac):
function lazygit() {
git add .
git commit -a -m "$1"
git push
}
This allows you to provide a commit message, such as
lazygit "My commit msg"
You could of course beef this up even more by accepting even more arguments, such as which remote place to push to, or which branch.
Use the JSON.stringify() to get the string in JSON format, ensure that while making the AJAX call you pass below mentioned attributes:

I tried to use more than two windows using the Rushy Panchal example above. The intent was to have the change to call more windows with different widgets in them. The butnew function creates different buttons to open different windows. You pass as argument the name of the class containing the window (the second argument is nt necessary, I put it there just to test a possible use. It could be interesting to inherit from another window the widgets in common.
import tkinter as tk
class Demo1:
def __init__(self, master):
self.master = master
self.master.geometry("400x400")
self.frame = tk.Frame(self.master)
self.butnew("Window 1", "ONE", Demo2)
self.butnew("Window 2", "TWO", Demo3)
self.frame.pack()
def butnew(self, text, number, _class):
tk.Button(self.frame, text = text, width = 25, command = lambda: self.new_window(number, _class)).pack()
def new_window(self, number, _class):
self.newWindow = tk.Toplevel(self.master)
_class(self.newWindow, number)
class Demo2:
def __init__(self, master, number):
self.master = master
self.master.geometry("400x400+400+400")
self.frame = tk.Frame(self.master)
self.quitButton = tk.Button(self.frame, text = 'Quit', width = 25, command = self.close_windows)
self.label = tk.Label(master, text=f"this is window number {number}")
self.label.pack()
self.quitButton.pack()
self.frame.pack()
def close_windows(self):
self.master.destroy()
class Demo3:
def __init__(self, master, number):
self.master = master
self.master.geometry("400x400+400+400")
self.frame = tk.Frame(self.master)
self.quitButton = tk.Button(self.frame, text = 'Quit', width = 25, command = self.close_windows)
self.label = tk.Label(master, text=f"this is window number {number}")
self.label.pack()
self.label2 = tk.Label(master, text="THIS IS HERE TO DIFFERENTIATE THIS WINDOW")
self.label2.pack()
self.quitButton.pack()
self.frame.pack()
def close_windows(self):
self.master.destroy()
def main():
root = tk.Tk()
app = Demo1(root)
root.mainloop()

To avoid having the chance to press multiple times the button having multiple windows... that are the same window, I made this script (take a look at this page too)
import tkinter as tk
def new_window1():
global win1
try:
if win1.state() == "normal": win1.focus()
except:
win1 = tk.Toplevel()
win1.geometry("300x300+500+200")
win1["bg"] = "navy"
lb = tk.Label(win1, text="Hello")
lb.pack()
win = tk.Tk()
win.geometry("200x200+200+100")
button = tk.Button(win, text="Open new Window")
button['command'] = new_window1
button.pack()
win.mainloop()
You can use:

A byte is 8 bits (binary data).
A byte array is an array of bytes (tautology FTW!).
You could use a byte array to store a collection of binary data, for example, the contents of a file. The downside to this is that the entire file contents must be loaded into memory.
For large amounts of binary data, it would be better to use a streaming data type if your language supports it.
Be careful of difference between 'c'
and "c"
'c'
is a char suitable for formatting with %c
"c"
is a char* pointing to a memory block with a length of 2 (with the null terminator).
Sometimes, you need to list the variables of an object and not for debugging purposes. The right way to do it is using get_object_vars($object). It returns an array that has all the class variables and their value. You can then loop through them in a foreach loop. If used within the object itself, simply do get_object_vars($this)
You must do the following command:
sort -n -k1 filename
That should do it :)

Here's how to find whether today is between 2 months:
private boolean isTodayBetween(int from, int to) {
if (from < 0 || to < 0 || from > Calendar.DECEMBER || to > Calendar.DECEMBER) {
throw new IllegalArgumentException("Invalid month provided: from = " + from + " to = " + to);
}
Date now = new Date();
GregorianCalendar cal = new GregorianCalendar();
cal.setTime(now);
int thisMonth = cal.get(Calendar.MONTH);
if (from > to) {
to = to + Calendar.DECEMBER;
thisMonth = thisMonth + Calendar.DECEMBER;
}
if (thisMonth >= from && thisMonth <= to) {
return true;
}
return false;
}
and call it like:
isTodayBetween(Calendar.OCTOBER, Calendar.MARCH)
cout << "\a";

I recommend to use both, prop and attr because I had problems with Chrome and I solved it using both functions.
if ($(':checkbox').is(':checked')){
$(':checkbox').prop('checked', true).attr('checked', 'checked');
}
else {
$(':checkbox').prop('checked', false).removeAttr('checked');
}
so I am assuming this is kinda out of use now but one way to do it is actually using document.body.style.zoom=2.0;
but if you do this then all of your canvas measurements will have to be divided by the zoom. Also, set the zoom higher for more aliasing. This is helpful because it is adjustable. Also if using this method, I suggest that you make functions to do the same as ctx.fillRect()
etc. but with the zoom taken into account. E.g.
function fillRect(x, y, width, height) {
var zoom = document.body.style.zoom;
ctx.fillRect(x/zoom, y/zoom, width/zoom, height/zoom);
}
Hope this helps!
Also, a sidenote: this can be used to sharpen circle edges as well so that they don't look as blurred. Just use a zoom such as 0.5!

Alternatively if you open the Debug perspective you will see all running apps in (by default) the top left. You can select the one that's causing you grief and once again hit the Big Red Button.
I don't think that it's possible for instance members to be removed before __del__
is called. My guess would be that the reason for your particular AttributeError is somewhere else (maybe you mistakenly remove self.file elsewhere).
However, as the others pointed out, you should avoid using __del__
. The main reason for this is that instances with __del__
will not be garbage collected (they will only be freed when their refcount reaches 0). Therefore, if your instances are involved in circular references, they will live in memory for as long as the application run. (I may be mistaken about all this though, I'd have to read the gc docs again, but I'm rather sure it works like this).
I experienced the problem mentioned by op
My case was that I was handed an old project and the tests were actually part of the system under test. I assume they were using the external test runner.

i was able to successfully run the Nunit tests.
To match regexes you need to use the =~
operator.
Try this:
[[ sed-4.2.2.tar.bz2 =~ tar.bz2$ ]] && echo matched
Alternatively, you can use wildcards (instead of regexes) with the ==
operator:
[[ sed-4.2.2.tar.bz2 == *tar.bz2 ]] && echo matched
If portability is not a concern, I recommend using [[
instead of [
or test
as it is safer and more powerful. See What is the difference between test, [ and [[ ? for details.
Its extremely simple, We can understand with simple date example, suppose if the date is mentioned as 1st January 2019 or 2nd May 2019 or any other date and we simply want to convert it to dd/mm/yyyy format we would not need the month's name which is January or February for that matter, so in order to capture the numeric part, but not the (optional) suffix you can use a non-capturing group.
so the regular expression would be,
([0-9]+)(?:January|February)?
Its as simple as that.

log.retention.hours
is a property of a broker which is used as a default value when a topic is created. When you change configurations of currently running topic using kafka-topics.sh
, you should specify a topic-level property.
A topic-level property for log retention time is retention.ms
.
From Topic-level configuration in Kafka 0.8.1 documentation:
So the correct command depends on the version. Up to 0.8.2 (although docs still show its use up to 0.10.1) use kafka-topics.sh --alter
and after 0.10.2 (or perhaps from 0.9.0 going forward) use kafka-configs.sh --alter
$ bin/kafka-topics.sh --zookeeper zk.yoursite.com --alter --topic as-access --config retention.ms=86400000
You can check whether the configuration is properly applied with the following command.
$ bin/kafka-topics.sh --describe --zookeeper zk.yoursite.com --topic as-access
Then you will see something like below.
Topic:as-access PartitionCount:3 ReplicationFactor:3 Configs:retention.ms=86400000
When you pass a string to the filter
function, the string is interpreted as SQL. Count is a SQL keyword and using count
as a variable confuses the parser. This is a small bug (you can file a JIRA ticket if you want to).
You can easily avoid this by using a column expression instead of a String:
df.groupBy("x").count()
.filter($"count" >= 2)
.show()
For MultiIndex you can extract its subindex using
df['si_name'] = R.index.get_level_values('si_name')
where si_name
is the name of the subindex.
Or in case you just need the value of the first seleted sell (or just one selected cell if one is selected)
TextBox1.Text = SelectedCells[0].Value.ToString();
If you use EF core add
.UseSerialColumn();
Example
modelBuilder.Entity<JobItem>(entity =>
{
entity.ToTable("jobs");
entity.Property(e => e.Id)
.HasColumnName("id")
.UseSerialColumn();
});

If your problem is like the following while using Google Chrome:
[XMLHttpRequest cannot load file. Received an invalid response. Origin 'null' is therefore not allowed access.]
Then create a batch file by following these steps:
Open notepad in Desktop.
start "chrome" "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --allow-file-access-from-files exit
This will do what? It will open Chrome.exe with file access. Now, from any location in your computer, browse your html files with Google Chrome. I hope this will solve the XMLHttpRequest problem.
Keep in mind : Just use the shortcut bat file to open Chrome when you require it. Tell me if it solves your problem. I had a similar problem and I solved it in this way. Thanks.

var option1 = new Option("new",true, true);
$('#status').append(option1);
$('#status').trigger('change');
Just be sure that the new option is one of the select2 options. I get this by a json.
copy your Dataframe column and simply apply
df=data['x']
newdf=df.str.lower()
You can only manually delete properties of objects. Thus:
var container = {};
container.instance = new class();
delete container.instance;
However, this won't work on any other pointers. Therefore:
var container = {};
container.instance = new class();
var pointer = container.instance;
delete pointer; // false ( ie attempt to delete failed )
Furthermore:
delete container.instance; // true ( ie attempt to delete succeeded, but... )
pointer; // class { destroy: function(){} }
So in practice, deletion is only useful for removing object properties themselves, and is not a reliable method for removing the code they point to from memory.
A manually specified destroy
method could unbind any event listeners. Something like:
function class(){
this.properties = { /**/ }
function handler(){ /**/ }
something.addEventListener( 'event', handler, false );
this.destroy = function(){
something.removeEventListener( 'event', handler );
}
}
If you are using Java 8, you could try something like this:
public Set<Number> difference(final Set<Number> set1, final Set<Number> set2){
final Set<Number> larger = set1.size() > set2.size() ? set1 : set2;
final Set<Number> smaller = larger.equals(set1) ? set2 : set1;
return larger.stream().filter(n -> !smaller.contains(n)).collect(Collectors.toSet());
}
Here is a good eplanation: ASP.NET MVC – Multiple buttons in the same form
In 2 words:
you may analize value of submitted button in yout action
or
make separate actions with your version of ActionMethodSelectorAttribute
(which I personaly prefer and suggest).
Luke's description of the function results in these scenarios seems to be right on. I only wish to understand the root cause and the PowerShell product team would do something about the behavior. It seems to be quite common and has cost me too much debugging time.
To get around this issue I've been using global variables rather than returning and using the value from the function call.
Here's another question on the use of global variables: Setting a global PowerShell variable from a function where the global variable name is a variable passed to the function
bash
has a "built-in" command called "echo":
$ type echo
echo is a shell builtin
Additionally, there is an "echo" command that is a proper executable (that is, the shell forks and execs /bin/echo
, as opposed to interpreting echo
and executing it):
$ ls -l /bin/echo
-rwxr-xr-x 1 root root 22856 Jul 21 2011 /bin/echo
The behavior of either echo
's WRT to \c
and -n
varies. Your best bet is to use printf
, which is available on four different *NIX flavors that I looked at:
$ printf "a line without trailing linefeed"
$ printf "a line with trailing linefeed\n"
The gap between the (bootstrap) input field and jquery-ui autocompleter seem to occur only in jQuery versions >= 3.2
When using jQuery version 3.1.1 it seem to not happen.
Possible reason is the notable update in v3.2.0 related to a bug fix on .width()
and .height()
. Check out the jQuery release notes for further details: v3.2.0 / v3.1.1
Bootstrap version 3.4.1 and jquery-ui version 1.12.0 used
QRGen is a good library that creates a layer on top of ZXing and makes QR Code generation in Java a piece of cake.
The difference between this two tables ItemBack1
and #ItemBack1
is that the first on is persistent (permanent) where as the other is temporary.
Now if take a look at your question again
Is it necessary to Use # for creating temp table in sql server?
The answer is Yes, because without this preceding #
the table will not be a temporary table, it will be independent of all sessions and scopes.
parser.add_argument
also has a switch required. You can use required=False
.
Here is a sample snippet with Python 2.7:
parser = argparse.ArgumentParser(description='get dir')
parser.add_argument('--dir', type=str, help='dir', default=os.getcwd(), required=False)
args = parser.parse_args()
In our case, in 2020 using Python3, the solution to this problem was to move the Python installation to the cloud-init
startup script which instantiated the VM.
We had been encountering this same error when we had been trying to install Python using scripts that were called by users later in the VM's life cycle, but moving the same Python installation code to the cloud-init
script eliminated this problem.
echo is alias to Write-Output although it looks the same as Write-Host.
It isn't What is the difference between echo and Write-Host in PowerShell?.
echo is an alias for Write-Output, which writes to the Success output stream. This allows output to be processed through pipelines or redirected into files. Write-Host writes directly to the console, so the output can't be redirected/processed any further.
If you really must use only standard libraries, then you just have to expand on Omar's solution a bit. (Apache's IOUtils is basically just a set of convenience methods which saves on a lot of coding)
You are already able to get the input stream through clobObject.getAsciiStream()
You just have to "manually transfer" the characters to the StringWriter:
InputStream in = clobObject.getAsciiStream();
Reader read = new InputStreamReader(in);
StringWriter write = new StringWriter();
int c = -1;
while ((c = read.read()) != -1)
{
write.write(c);
}
write.flush();
String s = write.toString();
Bear in mind that
Just my couple cents... sometimes it's good to be sure there are no any duplicates... so we have the next function in the utils library:
jQuery.loadCSS = function(url) {
if (!$('link[href="' + url + '"]').length)
$('head').append('<link rel="stylesheet" type="text/css" href="' + url + '">');
}
How to use:
$.loadCSS('css/style2.css');
I feel your pain as I, too, am starting out to get Django and React.js working together. Did a couple of Django projects, and I think, React.js is a great match for Django. However, it can be intimidating to get started. We are standing on the shoulders of giants here ;)
Here's how I think, it all works together (big picture, please someone correct me if I'm wrong).
Communication between Django and 'the frontend' is done via the Rest framework. Make sure you get your authorization and permissions for the Rest framework in place.
I found a good boiler template for exactly this scenario and it works out of the box. Just follow the readme https://github.com/scottwoodall/django-react-template and once you are done, you have a pretty nice Django Reactjs project running. By no means this is meant for production, but rather as a way for you to dig in and see how things are connected and working!
One tiny change I'd like to suggest is this: Follow the setup instructions BUT before you get to the 2nd step to setup the backend (Django here https://github.com/scottwoodall/django-react-template/blob/master/backend/README.md), change the requirements file for the setup.
You'll find the file in your project at /backend/requirements/common.pip Replace its content with this
appdirs==1.4.0
Django==1.10.5
django-autofixture==0.12.0
django-extensions==1.6.1
django-filter==1.0.1
djangorestframework==3.5.3
psycopg2==2.6.1
this gets you the latest stable version for Django and its Rest framework.
I hope that helps.
This is how i solved divider with horizontal lines and text in the midddle:
<View style={styles.divider}>
<View style={styles.hrLine} />
<Text style={styles.dividerText}>OR</Text>
<View style={styles.hrLine} />
</View>
And styles for this:
import { Dimensions, StyleSheet } from 'react-native'
const { width } = Dimensions.get('window')
const styles = StyleSheet.create({
divider: {
flexDirection: 'row',
alignItems: 'center',
marginTop: 10,
},
hrLine: {
width: width / 3.5,
backgroundColor: 'white',
height: 1,
},
dividerText: {
color: 'white',
textAlign: 'center',
width: width / 8,
},
})
