I had the same error code but different issue
Error: /Users/danieloram/desktop/CordovaProject/platforms/android/gradlew: Command failed with exit code 1 Error output:
Exception in thread "main" java.lang.UnsupportedClassVersionError: com/android/dx/command/Main : Unsupported major.minor version 52.0
To resolve this issue I opened the Android SDK Manager, uninstalled the latest Android SDK build-tools that I had (24.0.3) and installed version 23.0.3 of the build-tools.
My cordova app then proceeded to build successfully for android.

In Spring you can escape the html from JSP pages generated by <form>
tags. This closes off a lot avenues for XSS attacks, and can be done automatically in three ways:
For the entire application in the web.xml
file:
<context-param>
<param-name>defaultHtmlEscape</param-name>
<param-value>true</param-value>
</context-param>
For all forms on a given page in the file itself:
<spring:htmlEscape defaultHtmlEscape="true" />
For each form:
<form:input path="someFormField" htmlEscape="true" />
Please try the following code
Uri.fromFile(new File("/sdcard/sample.jpg"))
LibGDX is one of the best engines I've ever used, works on almost all platforms, and performs twice as fast as cocos2d-x in most tests I've done. You can use any JVM language you like. Here's a 13 part tutorial in Java, and here's a bunch using jruby. There's a good skeletal animation tool that works with it here, and it has baked in support for tiled TMX maps as well. The ui framework is awesome, and it has a scene graph and actor style API similar to cocos2d scenes, sprites and actions. The community is awesome, updates are frequent, and the documentation is good. Don't let the java part scare you, it's fast, and you can use jruby or scala or whatever you like. I highly recommend it for 2d or 3d work, it supports both.
Just do:
document.body.innerHTML = document.body.innerHTML + '<img src="../images/loaded.gif" alt="" onload="alert(\'test\');this.parentNode.removeChild(this);" />';
I have been using Mobilizer, which is an awesome free app
Currently it has default simulation for Iphone4, Iphone5, Samsung Galaxt S3, Nokia Lumia, Palm Pre, Blackberry Storm and HTC Evo. Simple straightforward and effective.
The problem you're having running from the command line is that you don't put ".class" after your class file.
java Practice 10 12
should work - as long as you're somewhere java can find the .class file.
Classpath issues are a whole 'nother story. If java still complains that it can't find your class, go to the same directory as your .class file (and it doesn't appear you're using packages...) and try -
java -cp . Practice 10 12

Note that the if $myVar; then ... ;fi
construct has a security problem you might want to avoid with
case $myvar in
(true) echo "is true";;
(false) echo "is false";;
(rm -rf*) echo "I just dodged a bullet";;
esac
You might also want to rethink why if [ "$myvar" = "true" ]
appears awkward to you. It's a shell string comparison that beats possibly forking a process just to obtain an exit status. A fork is a heavy and expensive operation, while a string comparison is dead cheap. Think a few CPU cycles versus several thousand. My case
solution is also handled without forks.
There is a quick method to set the syntax:
Ctrl
+Shift
+P
,then type in the input box
ss + (which type you want set)
eg: ss html +Enter
and ss means "set syntax"
it is really quicker than check in the menu's checkbox.

another solution will be to grab the text inside the title
tag & then use .html()
method of jQuery to construct the content of the tooltip.
$(function() {
$(document).tooltip({
position: {
using: function(position, feedback) {
$(this).css(position);
var txt = $(this).text();
$(this).html(txt);
$("<div>")
.addClass("arrow")
.addClass(feedback.vertical)
.addClass(feedback.horizontal)
.appendTo(this);
}
}
});
});
its tempting say as white space or integer 0 as per below proof
char c1 = '\u0000';
System.out.println("*"+c1+"*");
System.out.println((int)c1);
but i wouldn't say so because, it might differ it different platforms or in future. What i really care is i ll never use this default value, so before using any char just check it is \u0000 or not, then use it to avoid misconceptions in programs. Its as simple as that.
Change the checkboxes so that the name includes the index inside the brackets:
<input type="checkbox" class="checkbox_veh" id="checkbox_addveh<?php echo $i; ?>" <?php if ($vehicle_feature[$i]->check) echo "checked"; ?> name="feature[<?php echo $i; ?>]" value="<?php echo $vehicle_feature[$i]->id; ?>">
The checkboxes that aren't checked are never submitted. The boxes that are checked get submitted, but they get numbered consecutively from 0, and won't have the same indexes as the other corresponding input fields.
If you have trouble with caching ajax you can turn it off:
$.ajaxSetup({cache: false});
Don't know about best, but this one is at least correct, as long as the addresses have their comments stripped and replaced with whitespace.
Seriously. You should use an already written library for validating emails. The best way is probably to just send a verification e-mail to that address.
I think the question is a little bit fuzzy - for example, it can be interpreted as a question about best practices in programming loops with if
inside. So, I'll try to answer this question with this particular interpretation.
If you have if
inside a loop, then in most cases you'd like to know how the loop has ended - was it "broken" by the if
or was it ended "naturally"? So, your sample code can be modified in this way:
bool intMaxFound = false;
for (size = 0; size < HAY_MAX; size++)
{
// wait for hay until EOF
printf("\nhaystack[%d] = ", size);
int straw = GetInt();
if (straw == INT_MAX)
{intMaxFound = true; break;}
// add hay to stack
haystack[size] = straw;
}
if (intMaxFound)
{
// ... broken
}
else
{
// ... ended naturally
}
The problem with this code is that the if
statement is buried inside the loop body, and it takes some effort to locate it and understand what it does. A more clear (even without the break
statement) variant will be:
bool intMaxFound = false;
for (size = 0; size < HAY_MAX && !intMaxFound; size++)
{
// wait for hay until EOF
printf("\nhaystack[%d] = ", size);
int straw = GetInt();
if (straw == INT_MAX)
{intMaxFound = true; continue;}
// add hay to stack
haystack[size] = straw;
}
if (intMaxFound)
{
// ... broken
}
else
{
// ... ended naturally
}
In this case you can clearly see (just looking at the loop "header") that this loop can end prematurely. If the loop body is a multi-page text, written by somebody else, then you'd thank its author for saving your time.
UPDATE:
Thanks to SO - it has just suggested the already answered question about crash of the AT&T phone network in 1990. It's about a risky decision of C creators to use a single reserved word break
to exit from both loops and switch
.
Anyway this interpretation doesn't follow from the sample code in the original question, so I'm leaving my answer as it is.

Based on this answer, one-liner for simple cases (Python 3 code):
from urllib.parse import urlparse, urlencode
url = "https://stackoverflow.com/search?q=question"
params = {'lang':'en','tag':'python'}
url += ('&' if urlparse(url).query else '?') + urlencode(params)
or:
url += ('&', '?')[urlparse(url).query == ''] + urlencode(params)
It's the domain name spelt out in reverse.
For example, one of my domains is hedgee.com. So, I use com.hedgee
as the base name of all my packages.
You could use the .not function like the following examples to remove items that have an exact id, id containing a specific word, id starting with a word, etc... see http://www.w3schools.com/jquery/jquery_ref_selectors.asp for more information on jQuery selectors.
Ignore by Exact ID:
$(".thisClass").not('[id="thisId"]').doAction();
Ignore ID's that contains the word "Id"
$(".thisClass").not('[id*="Id"]').doAction();
Ignore ID's that start with "my"
$(".thisClass").not('[id^="my"]').doAction();
On the actual behavior, there is no difference. They all return None
and that's it. However, there is a time and place for all of these.
The following instructions are basically how the different methods should be used (or at least how I was taught they should be used), but they are not absolute rules so you can mix them up if you feel necessary to.
return None
This tells that the function is indeed meant to return a value for later use, and in this case it returns None
. This value None
can then be used elsewhere. return None
is never used if there are no other possible return values from the function.
In the following example, we return person
's mother
if the person
given is a human. If it's not a human, we return None
since the person
doesn't have a mother
(let's suppose it's not an animal or something).
def get_mother(person):
if is_human(person):
return person.mother
else:
return None
return
This is used for the same reason as break
in loops. The return value doesn't matter and you only want to exit the whole function. It's extremely useful in some places, even though you don't need it that often.
We've got 15 prisoners
and we know one of them has a knife. We loop through each prisoner
one by one to check if they have a knife. If we hit the person with a knife, we can just exit the function because we know there's only one knife and no reason the check rest of the prisoners
. If we don't find the prisoner
with a knife, we raise an alert. This could be done in many different ways and using return
is probably not even the best way, but it's just an example to show how to use return
for exiting a function.
def find_prisoner_with_knife(prisoners):
for prisoner in prisoners:
if "knife" in prisoner.items:
prisoner.move_to_inquisition()
return # no need to check rest of the prisoners nor raise an alert
raise_alert()
Note: You should never do var = find_prisoner_with_knife()
, since the return value is not meant to be caught.
return
at allThis will also return None
, but that value is not meant to be used or caught. It simply means that the function ended successfully. It's basically the same as return
in void
functions in languages such as C++ or Java.
In the following example, we set person's mother's name and then the function exits after completing successfully.
def set_mother(person, mother):
if is_human(person):
person.mother = mother
Note: You should never do var = set_mother(my_person, my_mother)
, since the return value is not meant to be caught.
There are two uses for RAISE_APPLICATION_ERROR. The first is to replace generic Oracle exception messages with our own, more meaningful messages. The second is to create exception conditions of our own, when Oracle would not throw them.
The following procedure illustrates both usages. It enforces a business rule that new employees cannot be hired in the future. It also overrides two Oracle exceptions. One is DUP_VAL_ON_INDEX, which is thrown by a unique key on EMP(ENAME)
. The other is a a user-defined exception thrown when the foreign key between EMP(MGR)
and EMP(EMPNO)
is violated (because a manager must be an existing employee).
create or replace procedure new_emp
( p_name in emp.ename%type
, p_sal in emp.sal%type
, p_job in emp.job%type
, p_dept in emp.deptno%type
, p_mgr in emp.mgr%type
, p_hired in emp.hiredate%type := sysdate )
is
invalid_manager exception;
PRAGMA EXCEPTION_INIT(invalid_manager, -2291);
dummy varchar2(1);
begin
-- check hiredate is valid
if trunc(p_hired) > trunc(sysdate)
then
raise_application_error
(-20000
, 'NEW_EMP::hiredate cannot be in the future');
end if;
insert into emp
( ename
, sal
, job
, deptno
, mgr
, hiredate )
values
( p_name
, p_sal
, p_job
, p_dept
, p_mgr
, trunc(p_hired) );
exception
when dup_val_on_index then
raise_application_error
(-20001
, 'NEW_EMP::employee called '||p_name||' already exists'
, true);
when invalid_manager then
raise_application_error
(-20002
, 'NEW_EMP::'||p_mgr ||' is not a valid manager');
end;

Note the different output from the two calls to RAISE_APPLICATION_ERROR in the EXCEPTIONS block. Setting the optional third argument to TRUE means RAISE_APPLICATION_ERROR includes the triggering exception in the stack, which can be useful for diagnosis.

No extensions are needed, just use these two functions for simple profiling.
// Call this at each point of interest, passing a descriptive string
function prof_flag($str)
{
global $prof_timing, $prof_names;
$prof_timing[] = microtime(true);
$prof_names[] = $str;
}
// Call this when you're done and want to see the results
function prof_print()
{
global $prof_timing, $prof_names;
$size = count($prof_timing);
for($i=0;$i<$size - 1; $i++)
{
echo "<b>{$prof_names[$i]}</b><br>";
echo sprintf(" %f<br>", $prof_timing[$i+1]-$prof_timing[$i]);
}
echo "<b>{$prof_names[$size-1]}</b><br>";
}
Here is an example, calling prof_flag() with a description at each checkpoint, and prof_print() at the end:
prof_flag("Start");
include '../lib/database.php';
include '../lib/helper_func.php';
prof_flag("Connect to DB");
connect_to_db();
prof_flag("Perform query");
// Get all the data
$select_query = "SELECT * FROM data_table";
$result = mysql_query($select_query);
prof_flag("Retrieve data");
$rows = array();
$found_data=false;

{
$found_data=true;
$rows[] = $r;
}
prof_flag("Close DB");
mysql_close(); //close database connection

Hard real time systems uses preemptive version of priority scheduling, so that critical tasks get immediately scheduled, whereas soft real time systems uses non-preemptive version of the priority scheduling, which allows the present task to be finished before control is transferred to the higher priority task, causing additional delays. Thus the task deadlines are critically followed in Hard real time systems, whereas in soft real time systems they are handled not that seriously.
Just for posterity, here's the text from several external sources regarding the Excel file formats. Some of these have been mentioned in other answers to this question but without reproducing the essential content.
1. From Doug Mahugh, August 22, 2006:
...the new XLSB binary format. Like Open XML, it’s a full-fidelity file format that can store anything you can create in Excel, but the XLSB format is optimized for performance in ways that aren’t possible with a pure XML format.
The XLSB format (also sometimes referred to as BIFF12, as in “binary file format for Office 12”) uses the same Open Packaging Convention used by the Open XML formats and XPS. So it’s basically a ZIP container, and you can open it with any ZIP tool to see what’s inside. But instead of .XML parts within the package, you’ll find .BIN parts...
This article also refers to documentation about the BIN format, too lengthy to reproduce here.
2. From MSDN Archive, August 29, 2006 which in turn cites an already-missing blog post regarding the XLSB format:
Even though we’ve done a lot of work to make sure that our XML formats open quickly and efficiently, this binary format is still more efficient for Excel to open and save, and can lead to some performance improvements for workbooks that contain a lot of data, or that would require a lot of XML parsing during the Open process. (In fact, we’ve found that the new binary format is faster than the old XLS format in many cases.) Also, there is no macro-free version of this file format – all XLSB files can contain macros (VBA and XLM). In all other respects, it is functionally equivalent to the XML file format above:
File size – file size of both formats is approximately the same, since both formats are saved to disk using zip compression Architecture – both formats use the same packaging structure, and both have the same part-level structures. Feature support – both formats support exactly the same feature set Runtime performance – once loaded into memory, the file format has no effect on application/calculation speed Converters – both formats will have identical converter support
Not a complete answer, but one specific situation where I've received this is when trying to access an object that 'died' because I tried to use autorelease:
netObjectDefinedInMyHeader = [[[MyNetObject alloc] init] autorelease];
So for example, I was actually passing this as an object to 'notify' (registered it as a listener, observer, whatever idiom you like) but it had already died once the notification was sent and I'd get the EXC_BAD_ACCESS. Changing it to [[MyNetObject alloc] init]
and releasing it later as appropriate solved the error.
Another reason this may happen is for example if you pass in an object and try to store it:
myObjectDefinedInHeader = aParameterObjectPassedIn;
Later when trying to access myObjectDefinedInHeader you may get into trouble. Using:
myObjectDefinedInHeader = [aParameterObjectPassedIn retain];
may be what you need. Of course these are just a couple of examples of what I've ran into and there are other reasons, but these can prove elusive so I mention them. Good luck!
Just had similar problem in Eclipse fixed with:
rightclick on project->Properties->Deployment Assembly->add Maven Dependencies
something kicked it out before, while I was editing my pom.xml
I had all needed jar files, taglib uri and web.xml was ok
if you want a nav bar do
ul{ list-style-type: none; } li{text-decoration: none;
with the < a > tag:
a:link {text-decoration: none}
// store the startTime prop in local state
const [startTime, setStartTime] = useState(props.startTime)
//
useEffect(() => {
if (props.startTime !== startTime) {
setStartTime(props.startTime);
}
}, [props.startTime]);
Can this method be migrated to class components?
Here's the code I've been using. It requires adding the attached property to each textbox you wish to auto select. Seeing as I don't want every textbox in my application to do this, this was the best solution to me.
public class AutoSelectAll
{
public static bool GetIsEnabled(DependencyObject obj)
{
return (bool)obj.GetValue(IsEnabledProperty);
}
public static void SetIsEnabled(DependencyObject obj, bool value)
{
obj.SetValue(IsEnabledProperty, value);
}
static void ue_Loaded(object sender, RoutedEventArgs e)
{
var ue = sender as FrameworkElement;
if (ue == null)
return;
ue.GotFocus += ue_GotFocus;
ue.GotMouseCapture += ue_GotMouseCapture;
}
private static void ue_Unloaded(object sender, RoutedEventArgs e)
{
var ue = sender as FrameworkElement;
if (ue == null)
return;
//ue.Unloaded -= ue_Unloaded;
ue.GotFocus -= ue_GotFocus;
ue.GotMouseCapture -= ue_GotMouseCapture;
}
static void ue_GotFocus(object sender, RoutedEventArgs e)
{
if (sender is TextBox)
{
(sender as TextBox).SelectAll();
}
e.Handled = true;
}
static void ue_GotMouseCapture(object sender, MouseEventArgs e)
{
if (sender is TextBox)
{
(sender as TextBox).SelectAll();
}
e.Handled = true;
}
public static readonly DependencyProperty IsEnabledProperty = DependencyProperty.RegisterAttached("IsEnabled", typeof(bool),
typeof(AutoSelectAll), new UIPropertyMetadata(false, IsEnabledChanged));
static void IsEnabledChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
var ue = d as FrameworkElement;
if (ue == null)
return;
if ((bool)e.NewValue)
{
ue.Unloaded += ue_Unloaded;
ue.Loaded += ue_Loaded;
}
}
}
The main change I made here was adding a loaded event to many of the examples I've seen. This allows the code to continue working after it's unloaded (ie. a tab is changed). Also I included code to make sure the text gets selected if you click on the textbox with the mouse, and not just keyboard focus it. Note: If you actually click on the text in the textbox, the cursor is inserted between the letters as it should.
You can use this by including the following tag in your xaml.
<TextBox
Text="{Binding Property}"
Library:AutoSelectAll.IsEnabled="True" />
downloaded Sql server management 2008 r2 and got it installed. Its getting installed but when I try to connect it via .\SQLEXPRESS it shows error. DO I need to install any SQL service on my system?
You installed management studio which is just a management interface to SQL Server. If you didn't (which is what it seems like) already have SQL Server installed, you'll need to install it in order to have it on your system and use it.

use alert(ie);
Testing:
var browserVersionExplorer = (function() {_x000D_
var ie = '<s>NotIE</s>',_x000D_
me = '<s>NotIE</s>';_x000D_
_x000D_
if (/msie\s|trident\/|edge\//i.test(window.navigator.userAgent) && !!(document.documentMode || document.uniqueID || window.ActiveXObject || window.MSInputMethodContext)) {_x000D_
if (!!window.MSInputMethodContext) {_x000D_
ie = !("ActiveXObject" in window) ? 'EDGE' : 11;_x000D_
} else if (!!document.uniqueID) {_x000D_
if (!!(window.ActiveXObject && document.all)) {_x000D_

Now we could use something easier and simpler:
var uA = window.navigator.userAgent,
onlyIEorEdge = /msie\s|trident\/|edge\//i.test(uA) && !!( document.uniqueID || window.MSInputMethodContext),
checkVersion = (onlyIEorEdge && +(/(edge\/|rv:|msie\s)([\d.]+)/i.exec(uA)[2])) || NaN;
It looks like you were on the right track - get_FOO_display()
is most certainly what you want:
In templates, you don't include ()
in the name of a method. Do the following:
{{ person.get_gender_display }}
Compare two values: the normal double, and the double after floor
ing it. If they are the same value, there is no decimal component.
I think the beginning to the resolution to this issue is the fact that the use of the for loop or any other function or action can not be done in the class definition but needs to be included in a method/constructor/block definition inside of a class.
As an addition to mklement0's excellent answer:
Almost all executables accept \"
as an escaped "
. Safe usage in cmd however is almost only possible using DELAYEDEXPANSION.
To explicitely send a literal "
to some process, assign \"
to an environment variable, and then use that variable, whenever you need to pass a quote. Example:
SETLOCAL ENABLEDELAYEDEXPANSION
set q=\"
child "malicious argument!q!&whoami"
Note SETLOCAL ENABLEDELAYEDEXPANSION
seems to work only within batch files. To get DELAYEDEXPANSION in an interactive session, start cmd /V:ON
.
If your batchfile does't work with DELAYEDEXPANSION, you can enable it temporarily:
::region without DELAYEDEXPANSION
SETLOCAL ENABLEDELAYEDEXPANSION
::region with DELAYEDEXPANSION
set q=\"
echoarg.exe "ab !q! & echo danger"
ENDLOCAL
::region without DELAYEDEXPANSION
If you want to pass dynamic content from a variable that contains quotes that are escaped as ""
you can replace ""
with \"
on expansion:
SETLOCAL ENABLEDELAYEDEXPANSION
foo.exe "danger & bar=region with !dynamic_content:""=\"! & danger"
ENDLOCAL
This replacement is not safe with %...%
style expansion!
In case of OP bash -c "g++-linux-4.1 !v_params:"=\"!"
is the safe version.
If for some reason even temporarily enabling DELAYEDEXPANSION is not an option, read on:
Using \"
from within cmd is a little bit safer if one always needs to escape special characters, instead of just sometimes. (It's less likely to forget a caret, if it's consistent...)
To achieve this, one precedes any quote with a caret (^"
), quotes that should reach the child process as literals must additionally be escaped with a backlash (\^"
). ALL shell meta characters must be escaped with ^
as well, e.g. &
=> ^&
; |
=> ^|
; >
=> ^>
; etc.
Example:
child ^"malicious argument\^"^&whoami^"
Source: Everyone quotes command line arguments the wrong way, see "A better method of quoting"
To pass dynamic content, one needs to ensure the following:
The part of the command that contains the variable must be considered "quoted" by cmd.exe
(This is impossible if the variable can contain quotes - don't write %var:""=\"%
). To achieve this, the last "
before the variable and the first "
after the variable are not ^
-escaped. cmd-metacharacters between those two "
must not be escaped. Example:
foo.exe ^"danger ^& bar=\"region with %dynamic_content% & danger\"^"
This isn't safe, if %dynamic_content%
can contain unmatched quotes.
When you say you increased MAVEN_OPTS
, what values did you increase? Did you increase the MaxPermSize
, as in example:
export MAVEN_OPTS="-Xmx512m -XX:MaxPermSize=128m"
(or on Windows:)
set MAVEN_OPTS=-Xmx512m -XX:MaxPermSize=128m
You can also specify these JVM options in each maven project separately.
As the question is asked years ago, and Android is evolved a lot on this URI scheme.
From original URI scheme, to deep link, and now Android App Links.
Android now recommends to use HTTP URLs, not define your own URI scheme. Because Android App Links use HTTP URLs that link to a website domain you own, so no other app can use your links. You can check the comparison of deep link and Android App links from here
Now you can easily add a URI scheme by using Android Studio option: Tools > App Links Assistant. Please refer the detail to Android document: https://developer.android.com/studio/write/app-link-indexing.html
In chart.js 2.1.6, I did something like this (in typescript):
let that = this;
options = {
legend: {
display: false,
responsive: false
},
tooltips: {
callbacks: {
label: function(tooltipItem, data) {
let account: Account = that.accounts[tooltipItem.index];
return account.accountNumber+":"+account.balance+"€";
}
}
}
}
The integer math solution that Ian provided is nice, but suffers from an integer overflow bug. Assuming the variables are all int
, the solution could be rewritten to use long
math and avoid the bug:
int pageCount = (-1L + records + recordsPerPage) / recordsPerPage;
If records
is a long
, the bug remains. The modulus solution does not have the bug.
If you are able to read the excel file correctly and only the integer values are not showing up. you can specify like this.
df = pd.read_excel('my.xlsx',sheetname='Sheet1', engine="openpyxl", dtype=str)
this should change your integer values into a string and show in dataframe
grep is your good friend to achieve this.
grep -r <text_fo_find> <directory>
If you don't care about the case of the text to find, then use:
grep -ir <text_to_find> <directory>
In Eclipse,
Go to your class,
Right click->source->Generate toString()
;
It will override the toString()
method and will print the object of that class.
ALTER TABLE
listing
ADDcount
INT(5), ADDlog
VARCHAR(200), ADDstatus
VARCHAR(20) AFTER stat
It will give good results.
A simple Approach can be if your Columns are of Simple Type like String
public static IEnumerable<MyObject> WhereQuery(IEnumerable<MyObject> source, string columnName, string propertyValue)
{
return source.Where(m => { return m.GetType().GetProperty(columnName).GetValue(m, null).ToString().StartsWith(propertyValue); });
}
Regarding #2, according to the JSR-330 spec:
This package provides dependency injection annotations that enable portable classes, but it leaves external dependency configuration up to the injector implementation.
So it's up to the provider to determine which objects are available for injection. In the case of Spring it is all Spring beans. And any class annotated with JSR-330 annotations are automatically added as Spring beans when using an AnnotationConfigApplicationContext.
Here's another way of attaching the event based on W3C DOM Level 2 Events Specification:
transport_select.addEventListener(
'change',
function() { toggleSelect(this.id); },
false
);
in php
echo '<a href="' . $folder_path . '">Link text</a>';
or
<a href="<?=$folder_path?>">Link text</a>;
or
<a href="<?php echo $folder_path ?>">Link text</a>;
I think you can benefit from using a MemoryStream. You can fill it with the string bytes that you obtain by using the GetBytes method of the Encoding class.
Always build with at least minimal optimization. With -O0
, all analysis that the compiler could use to determine that execution cannot reach the end of the function has been disabled. This is why you're seeing the warning. The only time you should ever use -O0
is for step-by-line debugging, which is usually not a good debugging approach anyway, but it's what most people who got started with MSVC learned on...
in server, i have a variable is: global.isSsr = true and in each reducer, i have a const is : initialState To reset the data in the Store, I do the following with each Reducer: example with appReducer.js:
const initialState = {
auth: {},
theme: {},
sidebar: {},
lsFanpage: {},
lsChatApp: {},
appSelected: {},
};
export default function (state = initialState, action) {
if (typeof isSsr!=="undefined" && isSsr) { //<== using global.isSsr = true
state = {...initialState};//<= important "will reset the data every time there is a request from the client to the server"
}
switch (action.type) {
//...other code case here
default: {
return state;
}
}
}
finally on the server's router:
router.get('*', (req, res) => {
store.dispatch({type:'reset-all-blabla'});//<= unlike any action.type // i use Math.random()
// code ....render ssr here
});
One can remove folder with cached jars.
In my case, on Mac the library was cached at path:
/Users/MY_NAME/.gradle/caches/modules-2/files-2.1/cached-library-to-remove
I removed the cached library folder ("cached-library-to-remove" in above example), deleted the build folder of my project and compiled again. Fresh library was downloaded then.
Below is the code to do it in vtd-xml. It basically queries the XML with the XPath of "/xml/item/@name."
import com.ximpleware.*;
public class getAttrs{
public static void main(String[] s) throws VTDException{
VTDGen vg = new VTDGen();
if (!vg.parseFile("input.xml",false)) // turn off namespace
return;
VTDNav vn = vg.getNav();
AutoPilot ap = new AutoPilot(vn);
ap.selectXPath("/xml/item/@name");
int i=0;
while( (i=ap.evalXPath())!=-1){
System.out.println(" item name is ===>"+vn.toString(i+1));
}
}
}
First of all, what you have is a fully compiled program, not an object file, so drop the .o

Error 4 means "The cause was a user-mode read resulting in no page being found.". There's a tool that decodes it here.
Here's the definition from the kernel. Keep in mind that 4 means that bit 2 is set and no other bits are set. If you convert it to binary that becomes clear.
/*
* Page fault error code bits
* bit 0 == 0 means no page found, 1 means protection fault
* bit 1 == 0 means read, 1 means write
* bit 2 == 0 means kernel, 1 means user-mode

Now then, "ip 00007f9bebcca90d" means the instruction pointer was at 0x00007f9bebcca90d when the segfault happened.
"libQtWebKit.so.4.5.2[7f9beb83a000+f6f000]" tells you:

(general comment - other answers cover the details)
There's no reason that you should lose portability by using them.
You always have the option of creating a simple nil-effect "inline" or macro that will allow you to compile on other platforms with other compilers.
You just won't get the benefit of the optimization if you're on other platforms.
pd.to_numeric
with errors='coerce'
# Setup
s = pd.Series(['1', '2', '3', '4', '.'])
s

dtype: object
pd.to_numeric(s, errors='coerce')
0 1.0
1 2.0
2 3.0
3 4.0
4 NaN

If you need the NaN

.
pd.to_numeric(s, errors='coerce').fillna(0, downcast='infer')
0 1
1 2
2 3
3 4
4 0
dtype: float64
Note, downcast='infer'
will attempt to downcast floats to integers where possible. Remove the argument if you don't want that.
From v0.24+, pandas introduces a Nullable Integer type, which allows integers to coexist with NaNs. If you have integers in your column, you can use
pd.__version__ # '0.24.1' pd.to_numeric(s, errors='coerce').astype('Int32') 0 1 1 2 2 3 3 4 4 NaN dtype: Int32
There are other options to choose from as well, read the docs for more.
DataFrames
If you need to extend this to DataFrames, you will need to apply it to each row. You can do this using DataFrame.apply
.
# Setup.
np.random.seed(0)
df = pd.DataFrame({
'A' : np.random.choice(10, 5),
'C' : np.random.choice(10, 5),
'B' : ['1', '###', '...', 50, '234'],
'D' : ['23', '1', '...', '268', '$$']}
)[list('ABCD')]
df
A B C D
0 5 1 9 23
1 0 ### 3 1
2 3 ... 5 ...
3 3 50 2 268
4 7 234 4 $$
df.dtypes
A int64
B object
C int64
D object
dtype: object
df2 = df.apply(pd.to_numeric, errors='coerce')
df2
A B C D
0 5 1.0 9 23.0
1 0 NaN 3 1.0
2 3 NaN 5 NaN
3 3 50.0 2 268.0
4 7 234.0 4 NaN
df2.dtypes
A int64
B float64
C int64
D float64
dtype: object
You can also do this with DataFrame.transform
; although my tests indicate this is marginally slower:
df.transform(pd.to_numeric, errors='coerce')
A B C D
0 5 1.0 9 23.0
1 0 NaN 3 1.0
2 3 NaN 5 NaN
3 3 50.0 2 268.0
4 7 234.0 4 NaN
If you have many columns (numeric; non-numeric), you can make this a little more performant by applying pd.to_numeric
on the non-numeric columns only.
df.dtypes.eq(object)
A False
B True
C False
D True
dtype: bool
cols = df.columns[df.dtypes.eq(object)]
# Actually, `cols` can be any list of columns you need to convert.
cols
# Index(['B', 'D'], dtype='object')
df[cols] = df[cols].apply(pd.to_numeric, errors='coerce')
# Alternatively,
# for c in cols:
# df[c] = pd.to_numeric(df[c], errors='coerce')
df
A B C D
0 5 1.0 9 23.0
1 0 NaN 3 1.0
2 3 NaN 5 NaN
3 3 50.0 2 268.0
4 7 234.0 4 NaN
Applying pd.to_numeric
along the columns (i.e., axis=0
, the default) should be slightly faster for long DataFrames.
This is not an answer to the original question. But, as an original question is not a real-world problem it should not be a problem. I tried to explain to a friend what are promises in JavaScript and the difference between promise and callback.
Code below serves as an explanation:
//very basic callback example using setTimeout
//function a is asynchronous function
//function b used as a callback
function a (callback){
setTimeout (function(){
console.log ('using callback:');
let mockResponseData = '{"data": "something for callback"}';
if (callback){
callback (mockResponseData);
}
}, 2000);
}
function b (dataJson) {
let dataObject = JSON.parse (dataJson);
console.log (dataObject.data);
}
a (b);
//rewriting above code using Promise
//function c is asynchronous function
function c () {
return new Promise(function (resolve, reject) {
setTimeout (function(){
console.log ('using promise:');
let mockResponseData = '{"data": "something for promise"}';
resolve(mockResponseData);
}, 2000);
});
}
c().then (b);
If, after reading the other questions and viewing the links mentioned in the comment sections, you still can't figure it out, read on.
First of all, where you're going wrong is the offset.
It should look more like this...
set mydate=%date:~10,4%%date:~6,2%/%date:~4,2%
echo %mydate%
If the date was Tue 12/02/2013
then it would display it as 2013/02/12
.
To remove the slashes, the code would look more like
set mydate=%date:~10,4%%date:~7,2%%date:~4,2%
echo %mydate%
which would output 20130212
And a hint for doing it in the future, if mydate
equals something like %date:~10,4%%date:~7,2%
or the like, you probably forgot a tilde (~).
You can use a defaultdict for this.
from collections import defaultdict
d = defaultdict(list)
d['key'].append('mykey')
This is slightly more efficient than setdefault
since you don't end up creating new lists that you don't end up using. Every call to setdefault
is going to create a new list, even if the item already exists in the dictionary.
You could use x ** (1. / 3)
to compute the (floating-point) cube root of x
.
The slight subtlety here is that this works differently for negative numbers in Python 2 and 3. The following code, however, handles that:
def is_perfect_cube(x):
x = abs(x)
return int(round(x ** (1. / 3))) ** 3 == x
print(is_perfect_cube(63))
print(is_perfect_cube(64))
print(is_perfect_cube(65))
print(is_perfect_cube(-63))
print(is_perfect_cube(-64))
print(is_perfect_cube(-65))
print(is_perfect_cube(2146689000)) # no other currently posted solution
# handles this correctly
This takes the cube root of x
, rounds it to the nearest integer, raises to the third power, and finally checks whether the result equals x
.
The reason to take the absolute value is to make the code work correctly for negative numbers across Python versions (Python 2 and 3 treat raising negative numbers to fractional powers differently).
You can do this to bubble events to parent document:
$('iframe').load(function() {
var eventlist = 'click dblclick \
blur focus focusin focusout \
keydown keypress keyup \
mousedown mouseenter mouseleave mousemove mouseover mouseout mouseup mousemove \
touchstart touchend touchcancel touchleave touchmove';
var iframe = $('iframe').contents().find('html');
// Bubble events to parent
iframe.on(eventlist, function(event) {
$('html').trigger(event);
});
});
Just extend the eventlist for more events.
I know a lot of people are saying use eval. the eval() js function will call the compiler, and that can offer a series of security risks. It is best to avoid its usage where possible. The parse function offers a more secure alternative.
diff -y --suppress-common-lines file1 file2
As of today, the quick & easy way to do it is:
if (Float.compare(sectionID, currentSectionID) == 0) {...}
However, the docs do not clearly specify the value of the margin difference (an epsilon from @Victor 's answer) that is always present in calculations on floats, but it should be something reasonable as it is a part of the standard language library.
Yet if a higher or customized precision is needed, then
float epsilon = Float.MIN_NORMAL;
if(Math.abs(sectionID - currentSectionID) < epsilon){...}
is another solution option.
From Dockerfile reference:
The
ARG
instruction defines a variable that users can pass at build-time to the builder with the docker build command using the--build-arg <varname>=<value>
flag.The
ENV
instruction sets the environment variable<key>
to the value<value>
.
The environment variables set usingENV
will persist when a container is run from the resulting image.
So if you need build-time customization, ARG
is your best choice.
If you need run-time customization (to run the same image with different settings), ENV
is well-suited.
If I want to add let's say 20 (a random number) of extensions or any other feature that can be enable|disable
Given the number of combinations involved, using ENV
to set those features at runtime is best here.
But you can combine both by:
ARG
ARG
as an ENV
That is, with a Dockerfile including:
ARG var
ENV var=${var}
You can then either build an image with a specific var
value at build-time (docker build --build-arg var=xxx
), or run a container with a specific runtime value (docker run -e var=yyy
)
It seem like your Resort
method doesn't declare a compareTo
method. This method typically belongs to the Comparable
interface. Make sure your class implements it.
Additionally, the compareTo
method is typically implemented as accepting an argument of the same type as the object the method gets invoked on. As such, you shouldn't be passing a String
argument, but rather a Resort
.
Alternatively, you can compare the names of the resorts. For example
if (resortList[mid].getResortName().compareTo(resortName)>0)
Use following code to show menu instead go to href addres
function show_more_menu(e) {_x000D_
if( !confirm(`Go to ${e.target.href} ?`) ) e.preventDefault();_x000D_
}
_x000D_
<a href='more.php' onclick="show_more_menu(event)"> More >>> </a>
_x000D_
In C and C++, the &&
and ||
operators "short-circuit". That means that they only evaluate a parameter if required. If the first parameter to &&
is false, or the first to ||
is true, the rest will not be evaluated.
The code you posted is safe, though I question why you'd include an empty else
block.
I am sure there is ANT tags to do it but have used this 7zip hack in .bat script. I use http://www.7-zip.org/ command line tool. All the times I use this for changing jdbc url within j2ee context.xml file.
mkdir .\temp-install
c:\apps\commands\7za.exe x -y mywebapp.war META-INF/context.xml -otemp-install\mywebapp
..here I have small tool to replace text in xml file..
c:\apps\commands\7za.exe u -y -tzip mywebapp.war ./temp-install/mywebapp/*
rmdir /Q /S .\temp-install
You could extract entire .war file (its zip after all), delete files, replace files, add files, modify files and repackage to .war archive file. But changing one file in a large .war archive this might be best extracting specific file and then update original archive.
Based on the answer above from Daniel, here's my take using Python3.
import numpy
def circlepoints(points,radius,center):
shape = []
slice = 2 * 3.14 / points
for i in range(points):
angle = slice * i
new_x = center[0] + radius*numpy.cos(angle)
new_y = center[1] + radius*numpy.sin(angle)
p = (new_x,new_y)
shape.append(p)
return shape
print(circlepoints(100,20,[0,0]))
For fadeIn and fadeOut, only add this after super.onCreate(savedInstanceState) in your new Activity class. You don't need to create something else (No XML, no anim folder, no extra function).
overridePendingTransition(R.anim.abc_fade_in,R.anim.abc_fade_out);
I found the solution.
As said in the EDIT of my answer, a <div>
is misfunctioning in a <table>
.
So I wrote this code instead :
<tr id="hidden" style="display:none;">
<td class="depot_table_left">
<label for="sexe">Sexe</label>
</td>
<td>
<select type="text" name="sexe">
<option value="1">Sexe</option>
<option value="2">Joueur</option>
<option value="3">Joueuse</option>
</select>
</td>
</tr>
And this is working fine.
Thanks everybody ;)
Got it.

I assumed it'd figure out that the > operator returned a bool (per documentation). But apparently it is not so.

Only call time pass-by-reference is removed. So change:
call_user_func($func, &$this, &$client ...
To this:
call_user_func($func, $this, $client ...
&$this
should never be needed after PHP4 anyway period.
If you absolutely need $client to be passed by reference, update the function ($func) signature instead (function func(&$client) {
)
I have the same issue, I tried all the above solutions, but none of them worked for me. Then I searched the keywords in flutter directory, and found the following code. So I tried to delete bin/cache/.upgrade_lock

The current version of Json.net does not allow you to use the accepted answer code. A current alternative is:
public static object DeserializeFromStream(Stream stream)
{
var serializer = new JsonSerializer();
using (var sr = new StreamReader(stream))
using (var jsonTextReader = new JsonTextReader(sr))
{
return serializer.Deserialize(jsonTextReader);
}
}

You could use the Merge Functionality to achieve. Otherwise you can do:
declare @rowCount int
select @rowCount=@@RowCount
if @rowCount=0
begin
--insert....
I found this, and it works for me:

There are ways to change the default delimiter, as shown by other answers.
There are also ways to convert the raw output to csv with some bash scripting. There are 3 delimiters to consider though, not just \001. Things get a bit more complicated when your hive table has maps.
I wrote a bash script that can handle all 3 default delimiters (\001 \002 and \003) from hive and output a csv. The script and some more info are here:
Hive Default Delimiters to CSV
Hive's default delimiters are
Row Delimiter => Control-A ('\001') Collection Item Delimiter => Control-B ('\002') Map Key Delimiter => Control-C ('\003')
There are ways to change these delimiters when exporting tables but sometimes you might still get stuck needing to convert this to csv.
Here's a quick bash script that can handle a DB export that's segmented in multiple files and has the default delimiters. It will output a single CSV file.
It is assumed that the segments all have the naming convention 000*_0
INDIRECTORY="path/to/input/directory" for f in $INDIRECTORY/000*_0; do echo "Processing $f file.."; cat -v $f | LC_ALL=C sed -e "s/^/\"/g" | LC_ALL=C sed -e "s/\^A/\",\"/g" | LC_ALL=C sed -e "s/\^C\^B/\"\":\"\"\"\",\"\"/g" | LC_ALL=C sed -e "s/\^B/\"\",\"\"/g" | LC_ALL=C sed -e "s/\^C/\"\":\"\"/g" | LC_ALL=C sed -e "s/$/\"/g" > $f-temp done echo "you,can,echo,your,header,here,if,you,like" > $INDIRECTORY/final_output.csv cat $INDIRECTORY/*-temp >> $INDIRECTORY/final_output.csv rm $INDIRECTORY/*-temp
More explanation on the gist
I've also been looking for solution to this problem, here's what I eventually came up with:
function getTimeStr() {
var dt = new Date();
var d = dt.toLocaleDateString();
var t = dt.toLocaleTimeString();
t = t.replace(/\u200E/g, '');
t = t.replace(/^([^\d]*\d{1,2}:\d{1,2}):\d{1,2}([^\d]*)$/, '$1$2');
var result = d + ' ' + t;
return result;
}
You can try it here: http://jsfiddle.net/B5Zrx/
\u200E is some formatting character that I've seen on some IE version (it's unicode left-to-right mark).
I assume that if the formatted time contains something like "XX:XX:XX" then it must be time with seconds and I remove the last part, if I don't find this pattern, nothing is changed. Pretty safe, but there is a risk of leaving seconds in some weird circumstances.
I just hope that there is no locale that would change the order of formatted time parts (e.g. make it ss:mm:hh). This left-to-right mark is making me a bit nervous about that though, that is why I don't remove the right-to-left mark (\u202E) - I prefer to not find a match in this case and leave the time formatted with seconds in such case.
Just type 0b11111111 in python interactive interface:

apt-get install python-setuptools python-pip
or
apt-get install python3-setuptools python3-pip
you'd also want to install the python packages...
pip
is designed to upgrade python packages and not to upgrade python itself. pip
shouldn't try to upgrade python when you ask it to do so.
Don't type pip install python
but use an installer instead.
For Spring Users , Spring Security has a Base64 class in the org.springframework.security.crypto.codec
package that can also be used for encoding and decoding of Base64.
Ex.
public static String base64Encode(String token) {
byte[] encodedBytes = Base64.encode(token.getBytes());
return new String(encodedBytes, Charset.forName("UTF-8"));
}
public static String base64Decode(String token) {
byte[] decodedBytes = Base64.decode(token.getBytes());
return new String(decodedBytes, Charset.forName("UTF-8"));
}
5 days ago from a particular date:
$date = new DateTime('2008-12-02');
$date->sub(new DateInterval('P5D'));
echo $date->format('Y-m-d') . "\n";
The cleanest way to do it is by using html5 selectors api, specifically querySelectorAll()
.
var contentToRemove = document.querySelectorAll("#myid");
$(contentToRemove).remove();
The querySelectorAll()
function returns an array of dom elements matching a specific id. Once you have assigned the returned array to a var
, then you can pass it as an argument to jquery remove()
.
Extremeandy has mentioned as of Chrome 66 autoplay video has been disabled.
After looking into this I found that muted videos are still able to be autoplayed. In my case the video didn't have any audio, but adding muted to the video tag has fixed it:

The jackson API has changed:

Casting to an int
truncates the value. Adding 0.5
causes it to do proper rounding.
int y = (int)(x + 0.5);

Static makes the clock member a class member instead of an instance member. Without the static keyword you would need to create an instance of the Hello class (which has a clock member variable) - e.g.
Hello hello = new Hello();
hello.clock.sayTime();
Example fetch with authorization header:

Another option is, instead of floating, to set the white-space property nowrap to a parent div:
.parent {
white-space: nowrap;
}
and reset the white-space and use an inline-block display so the divs stay on the same line but you can still give it a width.
.child {
display:inline-block;
width:300px;
white-space: normal;
}
Here is a JSFiddle: https://jsfiddle.net/9g8ud31o/
This is a very tricky issue - even if you're familiar with how things are working in https with certificates (OTOH if you see my workaround, it seems very logical :)
If you want to connect to a GIT repository via http(s) from shell, you would make sure to have the public certificate stored (as file) on your machine. Then you would add that certificate to your GIT configuration
git config [--global] http.sslCAInfo "certificate"
(replace "certificate" with the complete path/name of the PEM file :)
For shell usage you would as well e.g. supply a '.netrc' provding your credentials for the http-server login. Having done that, you shall be able to do a 'git clone https://...' without any interactive provisioning of credentials.
However, for the Jenkins-service it's a bit different ... Here, the jenkins process needs to be aware of the server certificate - and it doesn't use the shell settings (in the meaning of the global git configuration file '.gitconfig') :P
What I needed to do is to add another parameter to the startup options of Jenkins.
... -Djavax.net.ssl.trustStore="keystore" ...
(replace "keystore" with the complete path/name like explained below :)
Now copy the keystore file of your webserver holding the certificate to some path (I know this is a dirty hack and not exactly secure :) and refer to it with the '-Djavax.net.ssl.trustStore=' parameter.
Now the Jenkins service will accept the certificate from the webserver providing the repository via https. Configure the GIT repository URL like
Note that you still require the '.netrc' under the jenkins-user home folder for the logon !!! Thus what I describe is to be seen as a workaround ... until a properly working credentials helper plugin is provided. IMHO this plugin (in its current version 1.9.4) is buggy.
I could never get the credentials-helper to work from Jenkins no matter what I tried :( At best I got to see some errors about the not accessible temporary credential helper file, etc. You can see lots of bugs reported about it in the Jenkins JIRA, but no fix.
So if somebody got it to work okay, please share the knowledge ...
P.S.: Using the Jenkins plugins in the following versions:
Credentials plugin 1.9.4, GIT client plugin 1.6.1, Jenkins GIT plugin 2.0.1
My approach would not be to start by writing your own API. Life's too short, and there are more pressing problems to solve. In this situation, I typically:
Start with something someone has already written. Odds are, it'll do what you want. You can always write your own later, if necessary. OpenCSV is as good a starting point as any.
$foo = Bar::getBeers(); $foo = $foo->toArray();
with location - in new GoogleMaps SDK:
mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(chLocation,14));
The object viewer in Acrobat is good but Windjack Solution's PDF Canopener allows better inspection with an eyedropper for selecting objects on page. Also permits modifications to be made to PDF.
Don't forget also the table prefixes if you installation don't use the default prefix.
That is because Java cannot find the Main attribute in the MANIFEST.MF file. The Main attribute is necessary to tell java which class it should use as the application's entry point. Inside the jar file, the MANIFEST.MF file is located in META-INF folder. Wondering how you could look at what's inside a jar file? Open the jar file with WinRAR.
The main attribute inside the MANIFEST.MF looks like this:
Main-Class: <packagename>.<classname>
You get this "no main manifest attribute" error when this line is missing from the MANIFEST.MF file.
It's really a huge mess to specify this attribute inside the MANIFEST.MF file.
Update: I just found a really neat way to specify the Application's entry point in eclipse. When you say Export,
Select Jar and next
[ give it a name in the next window ] and next
and next again
and you'll see " Select the class of the application entry point".
Just pick a class and Eclipse will automatically build a cool MANIFEST.MF for you.
The cause of this error for me was...
ng-if="{{myTrustSrc(chat.src)}}"
in my template
It causes the function myTrustSrc in my controller to be called in an endless loop. If I remove the ng-if from this line, then the problem is solved.
<iframe ng-if="chat.src" id='chat' name='chat' class='chat' ng-src="{{myTrustSrc(chat.src)}}"></iframe>
The function is only called a few times when ng-if isn't used. I still wonder why the function is called more than once with ng-src?
This is the function in the controller
$scope.myTrustSrc = function(src) {
return $sce.trustAsResourceUrl(src);
}
Just add the'order_by' clause to your code and modify it to look just like the one below.
$this->db->order_by('name', 'asc');
$result = $this->db->get($table);
There you go.
You can use xarg
:
ls | xargs -L 1 -d '\n' your-desired-command
-L 1
causes pass 1 item at a time
-d '\n'
splits the output of ls
based on new line.
you can also do this using mounted

methods:{
getUnits: function() {...}
},
mounted: function(){
this.$nextTick(this.getUnits)

Another way is with Arrays.setAll
, or Arrays.fill
:
String[] v = new String[1000];
Arrays.setAll(v, i -> Integer.toString(i * 30));
//v => ["0", "30", "60", "90"... ]
Arrays.fill(v, "initial value");
//v => ["initial value", "initial value"... ]
This is more usefull for initializing (possibly large) arrays where you can compute each element from its index.
Suppose we have 14 records of name
column in table
in group by
select name,count(*) as totalcount from person where name='Please fill out' group BY name;
it will give count in single row i.e 14
but in partition by
select row_number() over (partition by name) as total from person where name = 'Please fill out';
it will 14 rows of increase in count
As all are given answers I want to add little more. I had also faced the same issue.
Why did your query fail? You have,
SELECT pid FROM planets WHERE userid = NULL;
This will not give you the expected result, because from mysql doc
In SQL, the NULL value is never true in comparison to any other value, even NULL. An expression that contains NULL always produces a NULL value unless otherwise indicated in the documentation for the operators and functions involved in the expression.
Emphasis mine.
To search for column values that are
NULL
, you cannot use anexpr = NULL
test. The following statement returns no rows, becauseexpr = NULL
is never true for any expression
SELECT pid FROM planets WHERE userid IS NULL;
To test for NULL
, use the IS NULL
and IS NOT NULL
operators.
NULL
.NULL
.You need convert list
to numpy array
and then reshape
:
df = pd.DataFrame(np.array(my_list).reshape(3,3), columns = list("abc"))
print (df)
a b c
0 1 2 3
1 4 5 6
2 7 8 9
date('Y-m-d H:i:s')
. See the manual for more.
Issue Background:
I was getting following error when i try to run mvn clean install in my project and through Netbeans IDE clean and build option. This issue is due to certificate not available when we download through NET beans IDE/through command prompt, but able to download the files through the browser.

As the author of the linked webpage in the popular answer, I would like to add my last version of this simple helper function. It is much more solid.
I use json_encode()
to make a check for if the variable type is not necessary and also add a buffer to solve problems with frameworks. There not have a solid return or excessive usage of header()
.
/**
* Simple helper to debug to the console
*
* @param $data object, array, string $data
* @param $context string Optional a description.
*
* @return string
*/
function debug_to_console($data, $context = 'Debug in Console') {
// Buffering to solve problems frameworks, like header() in this and not a solid return.
ob_start();
$output = 'console.info(\'' . $context . ':\');';
$output .= 'console.log(' . json_encode($data) . ');';
$output = sprintf('<script>%s</script>', $output);
echo $output;
}
// $data is the example variable, object; here an array.
$data = [ 'foo' => 'bar' ];
debug_to_console($data);`
Also a simple example as an image to understand it much easier:

There simply is no console listening by default. Running in debug mode there is a console attached, but in a production environment it is as you suspected, the message just doesn't go anywhere because nothing is listening.
Untested but something like this should work:
var phrase = "THIS IS MY TEXT RIGHT NOW";
var rx = new System.Text.RegularExpressions.Regex(@"(?<=\w)\w");
var newString = rx.Replace(phrase,new MatchEvaluator(m=>m.Value.ToLowerInvariant()));
Essentially it says "preform a regex match on all occurrences of an alphanumeric character that follows another alphanumeric character and then replace it with a lowercase version of itself"
The real answer is : It depends
There are a couple factors to consider, the most obvious are : the cpu you are running these algorithms on and the implementation of the algorithms.
For instance, me and my friend both run the exact same openssl version and get slightly different results with different Intel Core i7 cpus.
My test at work with an Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz
The 'numbers' are in 1000s of bytes per second processed.
type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes
md5 64257.97k 187370.26k 406435.07k 576544.43k 649827.67k
sha1 73225.75k 202701.20k 432679.68k 601140.57k 679900.50k
And his with an Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz
The 'numbers' are in 1000s of bytes per second processed.
type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes
md5 51859.12k 156255.78k 350252.00k 513141.73k 590701.52k
sha1 56492.56k 156300.76k 328688.76k 452450.92k 508625.68k
We both are running the exact same binaries of OpenSSL 1.0.1j 15 Oct 2014 from the ArchLinux official package.
My opinion on this is that with the added security of sha1, cpu designers are more likely to improve the speed of sha1 and more programmers will be working on the algorithm's optimization than md5sum.
I guess that md5 will no longer be used some day since it seems that it has no advantage over sha1. I also tested some cases on real files and the results were always the same in both cases (likely limited by disk I/O).
md5sum of a large 4.6GB file took the exact same time than sha1sum of the same file, same goes with many small files (488 in the same directory). I ran the tests a dozen times and they were consitently getting the same results.
--
It would be very interesting to investigate this further. I guess there are some experts around that could provide a solid answer to why sha1 is getting faster than md5 on newer processors.

java.util.List;
instead of
java.awt.List;
I got the same problem! then realized that my directory was not empty. I found the solution in another thread: not able to delete the directory through Java
/**
* Force deletion of directory
* @param path
* @return
*/
static public boolean deleteDirectory(File path) {
if (path.exists()) {
File[] files = path.listFiles();
for (int i = 0; i < files.length; i++) {
if (files[i].isDirectory()) {
deleteDirectory(files[i]);
} else {
files[i].delete();
}
}
}
return (path.delete());
}
Use Control.ControlCollection.Find.
TextBox tbx = this.Controls.Find("textBox1", true).FirstOrDefault() as TextBox;
tbx.Text = "found!";
EDIT for asker:
Control[] tbxs = this.Controls.Find(txtbox_and_message[0,0], true);
if (tbxs != null && tbxs.Length > 0)
{
tbxs[0].Text = "Found!";
}
Part of the answer to 'handle' the 'Sequence has no elements' Exception in VB is to test for empty
If Not (myMap Is Nothing) Then
' execute code
End if
Where MyMap is the sequence queried returning empty/null. FYI
As stated by Harry Joy, you can do it on the onclick
attr like so:
<input type="button" onclick="func1();func2();" value="Call2Functions" />
Or, in your JS like so:
document.getElementById( 'Call2Functions' ).onclick = function()
{
func1();
func2();
};
Or, if you are assigning an onclick programmatically, and aren't sure if a previous onclick existed (and don't want to overwrite it):
var Call2FunctionsEle = document.getElementById( 'Call2Functions' ),
func1 = Call2FunctionsEle.onclick;
Call2FunctionsEle.onclick = function()
{
if( typeof func1 === 'function' )
{
func1();
}
func2();
};
If you need the functions run in scope of the element which was clicked, a simple use of apply could be made:
document.getElementById( 'Call2Functions' ).onclick = function()
{
func1.apply( this, arguments );
func2.apply( this, arguments );
};
sn -T <assembly>
in Visual Studio command line.
If an assembly is installed in the global assembly cache, it's easier to go to C:\Windows\assembly
and find it in the list of GAC assemblies.
On your specific case, you might be mixing type full name with assembly reference, you might want to take a look at MSDN.
const data = [{"b":1,"c":100},{"a":1,"b":1,"c":150},{"a":1,"b":2,"c":100},{"a":2,"b":1,"c":13}]
const result = data.reduce((r, e) => {
r['a'] += (e['a'] ? e['a'] : 0)
r['d'] += (e['b'] ? e['b'] : 0)
r['c'] += (e['c'] ? e['c'] : 0)
return r
}, {'a':0, 'd':0, 'c':0})
console.log(result)
`result` { a: 4, d: 5, c: 363 }
In lieu of Javascript, a shorter PHP-based solution could be:
<input type="date" name="date1" max=
<?php
echo date('Y-m-d');
?>
>
Don't do things like [A-Z] or [0-9]. Do \p{Lu} and \d instead. Of course, this is valid for perl based regex flavours. This includes java.
I would suggest that you don't make some huge regex. First split the text in sentences. then tokenize it (split into words). Use a regex to check each token/word. Skip the first token from sentence. Check if all tokens are uppercase beforehand and skip the whole sentence if so, or alter the regex in this case.
Try this SQL statement:
update Table set Column =( Column - your val )

The RFC for Websockets : RFC6455
It can be opened using Visual Studio 2012.Follow the below path in VS after opening the project. View->Server Explorer->
You can do one thing.
like:- In appsettings.config ->
<appSettings>
<add key="SqlCommandTimeOut" value="240"/>
</appSettings>
In Code ->
command.CommandTimeout = Convert.ToInt32(System.Configuration.ConfigurationManager.AppSettings["SqlCommandTimeOut"]);
That should do it.
Note:- I faced most of the timeout issues when I used SqlHelper class from microsoft application blocks. If you have it in your code and are facing timeout problems its better you use sqlcommand and set its timeout as described above. For all other scenarios sqlhelper should do fine. If your client is ok with waiting a little longer than what sqlhelper class offers you can go ahead and use the above technique.
example:- Use this -
SqlCommand cmd = new SqlCommand(completequery);
cmd.CommandTimeout = Convert.ToInt32(System.Configuration.ConfigurationManager.AppSettings["SqlCommandTimeOut"]);
SqlConnection con = new SqlConnection(sqlConnectionString);
SqlDataAdapter adapter = new SqlDataAdapter();
con.Open();
adapter.SelectCommand = new SqlCommand(completequery, con);
adapter.Fill(ds);
con.Close();
Instead of
DataSet ds = new DataSet();
ds = SqlHelper.ExecuteDataset(sqlConnectionString, CommandType.Text, completequery);
Update: Also refer to @Triynko answer below. It is important to check that too.

It's easy. If you have two or more running container, complete next steps:
docker network create myNetwork
docker network connect myNetwork web1
docker network connect myNetwork web2
Now you connect from web1 to web2 container or the other way round.
Use the internal network IP addresses which you can find by running:
docker network inspect myNetwork
Note that only internal IP addresses and ports are accessible to the containers connected by the network bridge.
So for example assuming that web1 container was started with: docker run -p 80:8888 web1
(meaning that its server is running on port 8888 internally), and inspecting myNetwork
shows that web1's IP is 172.0.0.2, you can connect from web2 to web1 using curl 172.0.0.2:8888
).
In Scala it is very comfortable with https://github.com/lloydmeta/enumeratum
Project is really good with examples and documentation
Just this example from their docs should makes you interested in
import enumeratum._
sealed trait Greeting extends EnumEntry
object Greeting extends Enum[Greeting] {
/*
`findValues` is a protected method that invokes a macro to find all `Greeting` object declarations inside an `Enum`
You use it to implement the `val values` member
*/
val values = findValues
case object Hello extends Greeting
case object GoodBye extends Greeting
case object Hi extends Greeting
case object Bye extends Greeting
}
// Object Greeting has a `withName(name: String)` method
Greeting.withName("Hello")
// => res0: Greeting = Hello
Greeting.withName("Haro")
// => java.lang.IllegalArgumentException: Haro is not a member of Enum (Hello, GoodBye, Hi, Bye)
// A safer alternative would be to use `withNameOption(name: String)` method which returns an Option[Greeting]
Greeting.withNameOption("Hello")
// => res1: Option[Greeting] = Some(Hello)
Greeting.withNameOption("Haro")
// => res2: Option[Greeting] = None
// It is also possible to use strings case insensitively
Greeting.withNameInsensitive("HeLLo")
// => res3: Greeting = Hello
Greeting.withNameInsensitiveOption("HeLLo")
// => res4: Option[Greeting] = Some(Hello)
// Uppercase-only strings may also be used
Greeting.withNameUppercaseOnly("HELLO")
// => res5: Greeting = Hello
Greeting.withNameUppercaseOnlyOption("HeLLo")
// => res6: Option[Greeting] = None
// Similarly, lowercase-only strings may also be used
Greeting.withNameLowercaseOnly("hello")
// => res7: Greeting = Hello
Greeting.withNameLowercaseOnlyOption("hello")
// => res8: Option[Greeting] = Some(Hello)

All of drop down lists disappeared in Build Settings after running the Fix Issue in Xcode 5. Spent several days trying to figure out what was wrong with my provisioning profiles and code signing. Found a link Xcode 4 missing drop down lists in Build Settings and sure enough I needed to re-enabled "Show Values" under the Editor menu. Hopefully this helps anyone else in this predicament.
Also, I had to clear my derived data, clean the solution and quit and reopen Xcode into for the code signing identities to correctly appear. My distribution provisioning profiles where showing up as signed by my developer certificate which was incorrect.
The legend titles can be labeled by specific aesthetic.
This can be achieved using the guides()
or labs()
functions from ggplot2
(more here and here). It allows you to add guide/legend properties using the aesthetic mapping.
Here's an example using the mtcars
data set and labs()
:
ggplot(mtcars, aes(x=mpg, y=disp, size=hp, col=as.factor(cyl), shape=as.factor(gear))) +
geom_point() +
labs(x="miles per gallon", y="displacement", size="horsepower",
col="# of cylinders", shape="# of gears")
Answering the OP's question using guides()
:
# transforming the data from wide to long
require(reshape2)
dfm <- melt(df, id="TY")
# creating a scatterplot
ggplot(data = dfm, aes(x=TY, y=value, color=variable)) +
geom_point(size=5) +
labs(title="Temperatures\n", x="TY [°C]", y="Txxx") +
scale_color_manual(labels = c("T999", "T888"), values = c("blue", "red")) +
theme_bw() +
guides(color=guide_legend("my title")) # add guide properties by aesthetic
Modern browsers now consider displaying a custom message to be a security hazard and it has therefore been removed from all of them. Browsers now only display generic messages. Since we no longer have to worry about setting the message, it is as simple as:
// Enable navigation prompt
window.onbeforeunload = function() {
return true;
};
// Remove navigation prompt
window.onbeforeunload = null;
Read below for legacy browser support.
The orginal answer is suitable for IE6-8 and FX1-3.5 (which is what we were targeting back in 2009 when it was written), but is rather out of date now and won't work in most current browsers - I've left it below for reference.
The window.onbeforeunload
is not treated consistently by all browsers. It should be a function reference and not a string (as the original answer stated) but that will work in older browsers because the check for most of them appears to be whether anything is assigned to onbeforeunload
(including a function that returns null
).
You set window.onbeforeunload
to a function reference, but in older browsers you have to set the returnValue
of the event instead of just returning a string:
var confirmOnPageExit = function (e)
{
// If we haven't been passed the event get the window.event
e = e || window.event;
var message = 'Any text will block the navigation and display a prompt';
// For IE6-8 and Firefox prior to version 4
if (e)
{
e.returnValue = message;
}
// For Chrome, Safari, IE8+ and Opera 12+
return message;
};
You can't have that confirmOnPageExit
do the check and return null if you want the user to continue without the message. You still need to remove the event to reliably turn it on and off:
// Turn it on - assign the function that returns the string
window.onbeforeunload = confirmOnPageExit;
// Turn it off - remove the function entirely
window.onbeforeunload = null;
To turn it on:
window.onbeforeunload = "Are you sure you want to leave?";
To turn it off:
window.onbeforeunload = null;
Bear in mind that this isn't a normal event - you can't bind to it in the standard way.
To check for values? That depends on your validation framework.
In jQuery this could be something like (very basic example):
$('input').change(function() {
if( $(this).val() != "" )
window.onbeforeunload = "Are you sure you want to leave?";
});
Note This is an improvement in @user3516549 answer and I have check it on Moto G3 with Android 6.0.1
I have this issue so I have tried answer of @user3516549 but in some cases it was not working properly.
I have found that in Android 6.0(or above) when we start gallery image pick intent then a screen will open that shows recent images when user select image from this list we will get uri as
content://com.android.providers.media.documents/document/image%3A52530
while if user select gallery from sliding drawer instead of recent then we will get uri as
content://media/external/images/media/52530
So I have handle it in getRealPathFromURI_API19()
public static String getRealPathFromURI_API19(Context context, Uri uri) {
String filePath = "";
if (uri.getHost().contains("com.android.providers.media")) {
// Image pick from recent
String wholeID = DocumentsContract.getDocumentId(uri);
// Split at colon, use second item in the array
String id = wholeID.split(":")[1];
String[] column = {MediaStore.Images.Media.DATA};
// where id is equal to
String sel = MediaStore.Images.Media._ID + "=?";
Cursor cursor = context.getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
column, sel, new String[]{id}, null);
int columnIndex = cursor.getColumnIndex(column[0]);
if (cursor.moveToFirst()) {
filePath = cursor.getString(columnIndex);
}
cursor.close();
return filePath;
} else {
// image pick from gallery
return getRealPathFromURI_BelowAPI11(context,uri)
}
}
EDIT1 : if you are trying to get image path of file in external sdcard in higher version then check my question
EDIT2 Here is complete code with handling virtual files and host other than com.android.providers
I have tested this method with content://com.adobe.scan.android.documents/document/
You cannot create different "variable names" but you can create different object properties. There are many ways to do whatever it is you're actually trying to accomplish. In your case I would just do
for (var i = myArray.length - 1; i >= 0; i--) { console.log(eval(myArray[i])); };
More generally you can create object properties dynamically, which is the type of flexibility you're thinking of.
var result = {}; for (var i = myArray.length - 1; i >= 0; i--) { result[myArray[i]] = eval(myArray[i]); };
I'm being a little handwavey since I don't actually understand language theory, but in pure Javascript (including Node) references (i.e. variable names) are happening at a higher level than at runtime. More like at the call stack; you certainly can't manufacture them in your code like you produce objects or arrays. Browsers do actually let you do this anyway though it's terrible practice, via
window['myVarName'] = 'namingCollisionsAreFun';
(per comment)
This may be overkill for what you're looking for, but there is an npm package called marky
that you can use to do this. It gives you a couple of extra features beyond just starting and stopping a timer.
You just need to install it via npm
and then import the dependency anywhere you'd like to use it.
Here is a link to the npm
package:
https://www.npmjs.com/package/marky
An example of use after installing via npm would be as follows:
import * as _M from 'marky';
@Component({
selector: 'app-test',
templateUrl: './test.component.html',
styleUrls: ['./test.component.scss']
})
export class TestComponent implements OnInit {
Marky = _M;
}
constructor() {}
ngOnInit() {}
startTimer(key: string) {
this.Marky.mark(key);
}
stopTimer(key: string) {
this.Marky.stop(key);
}
key
is simply a string which you are establishing to identify that particular measurement of time. You can have multiple measures which you can go back and reference your timer stats using the keys you create.
Here's a possible solution that will color the entire row for your table.
CSS
tr.highlighted td {
background: red;
}
jQuery
$('#data tr').click(function(e) {
$('#data tr').removeClass('highlighted');
$(this).toggleClass('highlighted');
});
The cleanest, shortest, and most reusable way is a self invoked anonymous function:
One line shorter than the top answer with anonymous method.
new Action(() =>
{
for (int x = 0; x < 100; x++)
{
for (int y = 0; y < 100; y++)
{
return; // exits self invoked lambda expression
}
}
})();
Console.WriteLine("Hi");
In pydev eclipse plugin, you may want to set the environment variable for DYLD. The path can be set as shown in
SELECT * FROM Table_Name LIMIT 5;
I'd build a list of keys that need removing, then remove them. It's simple, efficient and avoids any problem about simultaneously iterating over and mutating the dict.
keys_to_remove = [key for key, value in some_dict.iteritems()
if value == value_to_remove]
for key in keys_to_remove:
del some_dict[key]

You can do it like this.

String stringToConvert = "This String is 76 characters long and will be converted to an array of bytes";
byte[] theByteArray = stringToConvert.getBytes();

Byte array to String
byte[] byteArray = new byte[] {87, 79, 87, 46, 46, 46};
String value = new String(byteArray);
I solved this issue by changing the permission of my npm directory. I went to the npm global directory for me it was at
/home/<user-name>
I went to this directory by entering this command
cd /home/<user-name>
and then changed the permission of .npm folder by entering this command.
sudo chmod -R 777 ".npm"
It worked like a charm to me. But there is a security flaw with this i.e your global packages directory is accessible to all the levels.
Note: this answer is for ANTLR3! If you're looking for an ANTLR4 example, then this Q&A demonstrates how to create a simple expression parser, and evaluator using ANTLR4.
You first create a grammar. Below is a small grammar that you can use to evaluate expressions that are built using the 4 basic math operators: +, -, * and /. You can also group expressions using parenthesis.
Note that this grammar is just a very basic one: it does not handle unary operators (the minus in: -1+9) or decimals like .99 (without a leading number), to name just two shortcomings. This is just an example you can work on yourself.
Here's the contents of the grammar file Exp.g:
grammar Exp;
/* This will be the entry point of our parser. */
eval
: additionExp
;
/* Addition and subtraction have the lowest precedence. */
additionExp
: multiplyExp
( '+' multiplyExp
| '-' multiplyExp
)*
;
/* Multiplication and division have a higher precedence. */
multiplyExp
: atomExp
( '*' atomExp
| '/' atomExp
)*
;
/* An expression atom is the smallest part of an expression: a number. Or
when we encounter parenthesis, we're making a recursive call back to the
rule 'additionExp'. As you can see, an 'atomExp' has the highest precedence. */
atomExp
: Number
| '(' additionExp ')'
;
/* A number: can be an integer value, or a decimal value */
Number
: ('0'..'9')+ ('.' ('0'..'9')+)?
;
/* We're going to ignore all white space characters */
WS
: (' ' | '\t' | '\r'| '\n') {$channel=HIDDEN;}
;
(Parser rules start with a lower case letter, and lexer rules start with a capital letter)
After creating the grammar, you'll want to generate a parser and lexer from it. Download the ANTLR jar and store it in the same directory as your grammar file.
Execute the following command on your shell/command prompt:
java -cp antlr-3.2.jar org.antlr.Tool Exp.g
It should not produce any error message, and the files ExpLexer.java, ExpParser.java and Exp.tokens should now be generated.
To see if it all works properly, create this test class:
import org.antlr.runtime.*;
public class ANTLRDemo {
public static void main(String[] args) throws Exception {
ANTLRStringStream in = new ANTLRStringStream("12*(5-6)");
ExpLexer lexer = new ExpLexer(in);
CommonTokenStream tokens = new CommonTokenStream(lexer);
ExpParser parser = new ExpParser(tokens);
parser.eval();
}
}
and compile it:
// *nix/MacOS
javac -cp .:antlr-3.2.jar ANTLRDemo.java
// Windows
javac -cp .;antlr-3.2.jar ANTLRDemo.java
and then run it:
// *nix/MacOS
java -cp .:antlr-3.2.jar ANTLRDemo
// Windows
java -cp .;antlr-3.2.jar ANTLRDemo
If all goes well, nothing is being printed to the console. This means the parser did not find any error. When you change "12*(5-6)"
into "12*(5-6"
and then recompile and run it, there should be printed the following:
line 0:-1 mismatched input '<EOF>' expecting ')'
Okay, now we want to add a bit of Java code to the grammar so that the parser actually does something useful. Adding code can be done by placing {
and }
inside your grammar with some plain Java code inside it.
But first: all parser rules in the grammar file should return a primitive double value. You can do that by adding returns [double value]
after each rule:
grammar Exp;
eval returns [double value]
: additionExp
;
additionExp returns [double value]
: multiplyExp
( '+' multiplyExp
| '-' multiplyExp
)*
;
// ...
which needs little explanation: every rule is expected to return a double value. Now to "interact" with the return value double value
(which is NOT inside a plain Java code block {...}
) from inside a code block, you'll need to add a dollar sign in front of value
:
grammar Exp;
/* This will be the entry point of our parser. */
eval returns [double value]
: additionExp { /* plain code block! */ System.out.println("value equals: "+$value); }
;
// ...
Here's the grammar but now with the Java code added:
grammar Exp;
eval returns [double value]
: exp=additionExp {$value = $exp.value;}
;
additionExp returns [double value]
: m1=multiplyExp {$value = $m1.value;}
( '+' m2=multiplyExp {$value += $m2.value;}
| '-' m2=multiplyExp {$value -= $m2.value;}
)*
;
multiplyExp returns [double value]
: a1=atomExp {$value = $a1.value;}
( '*' a2=atomExp {$value *= $a2.value;}
| '/' a2=atomExp {$value /= $a2.value;}
)*
;
atomExp returns [double value]
: n=Number {$value = Double.parseDouble($n.text);}
| '(' exp=additionExp ')' {$value = $exp.value;}
;
Number
: ('0'..'9')+ ('.' ('0'..'9')+)?
;
WS
: (' ' | '\t' | '\r'| '\n') {$channel=HIDDEN;}
;
and since our eval
rule now returns a double, change your ANTLRDemo.java into this:
import org.antlr.runtime.*;
public class ANTLRDemo {
public static void main(String[] args) throws Exception {
ANTLRStringStream in = new ANTLRStringStream("12*(5-6)");
ExpLexer lexer = new ExpLexer(in);
CommonTokenStream tokens = new CommonTokenStream(lexer);
ExpParser parser = new ExpParser(tokens);
System.out.println(parser.eval()); // print the value
}
}
Again (re) generate a fresh lexer and parser from your grammar (1), compile all classes (2) and run ANTLRDemo (3):
// *nix/MacOS
java -cp antlr-3.2.jar org.antlr.Tool Exp.g // 1
javac -cp .:antlr-3.2.jar ANTLRDemo.java // 2
java -cp .:antlr-3.2.jar ANTLRDemo // 3
// Windows
java -cp antlr-3.2.jar org.antlr.Tool Exp.g // 1
javac -cp .;antlr-3.2.jar ANTLRDemo.java // 2
java -cp .;antlr-3.2.jar ANTLRDemo // 3
and you'll now see the outcome of the expression 12*(5-6)
printed to your console!
Again: this is a very brief explanation. I encourage you to browse the ANTLR wiki and read some tutorials and/or play a bit with what I just posted.
Good luck!
EDIT:
This post shows how to extend the example above so that a Map<String, Double>
can be provided that holds variables in the provided expression.
To get this code working with a current version of Antlr (June 2014) I needed to make a few changes. ANTLRStringStream
needed to become ANTLRInputStream
, the returned value needed to change from parser.eval()
to parser.eval().value
, and I needed to remove the WS
clause at the end, because attribute values such as $channel
are no longer allowed to appear in lexer actions.
Create a section called <connectionStrings></connectionStrings>
in your web.config
inside <configuration></configuration>
then add different connection strings to it, for example
<configuration>
<connectionStrings>
<add name="ConnectionStringName" providerName="System.Data.SqlClient" connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=DatabaseName;Integrated Security=True;MultipleActiveResultSets=True"/>
</connectionStrings>
</configuration>
Here's a list of all the different connection string formats https://msdn.microsoft.com/en-us/library/jj653752(v=vs.110).aspx
There is only one public signature allowed for each controller method. If you try to overload it, it will compile, but you're getting the run-time error you've experienced.
If you're not willing to use different verbs (like the [HttpGet]
and [HttpPost]
attributes) to differentiate overloaded methods (which will work), or change the routing, then what remains is that you can either provide another method with a different name, or you can dispatch inside of the existing method. Here's how I did it:
I once came into a situation where I had to maintain backwards compatibility. The original method expected two parameters, but the new one had only one. Overloading the way I expected did not work because MVC didn't find the entry point any more.
To solve that, I did the following:
Created one new public method which contained "just" 2 string parameters. That one acted as a dispatcher, i.e.:
public ActionResult DoSomething(string param1, string param2)
{
if (string.IsNullOrEmpty(param2))
{
return DoSomething(ProductName: param1);
}
else
{
int oldId = int.Parse(param1);
return DoSomething(OldParam: param1, OldId: oldId);
}
}
private ActionResult DoSomething(string OldParam, int OldId)
{
// some code here
return Json(result);
}
private ActionResult DoSomething(string ProductName)
{
// some code here
return Json(result);
}
Of course, this is a hack and should be refactored later. But for the time being, it worked for me.
You can also create a dispatcher like:
public ActionResult DoSomething(string action, string param1, string param2)
{
switch (action)
{
case "update":
return UpdateAction(param1, param2);
case "remove":
return DeleteAction(param1);
}
}
You can see, that UpdateAction needs 2 parameters, while DeleteAction just needs one.
It happens when $ret
hasn't been defined. The solution is simple. Right above $tags = get_tags();
, add the following line:
$ret = array();
For me in windows 7 it started to work only after I gave 'Read & execute', 'List folder contents', 'Read' permissions to site folder for both users

db.Database.SqlQuery<myEntityType>("exec GetNewSeqOfFoodServing @p0,@p1,@p2 ", foods_WEIGHT.NDB_No, HLP.CuntryID, HLP.ClientID).Single()
or
db.Database.SqlQuery<myEntityType>(
"exec GetNewSeqOfFoodServing @param1, @param2",
new SqlParameter("param1", param1),
new SqlParameter("param2", param2)
);
or
var cmdText = "exec [DoStuff] @Name = @name_param, @Age = @age_param";
var @params = new[]{
new SqlParameter("name_param", "Josh"),
new SqlParameter("age_param", 45)
};
db.Database.SqlQuery<myEntityType>(cmdText, @params)
or
db.Database.SqlQuery<myEntityType>("mySpName {0}, {1}, {2}",
new object[] { param1, param2, param3 }).ToList();
I am not sure what caused this but it went all well once I changed the path name from Lib
into lib
and I was finally able to make it work.
In my case, we have time series from different devices but some devices could not send any value during some period. So we should create NA values for every device and time period and after that do fillna.
df = pd.DataFrame([["device1", 1, 'first val of device1'], ["device2", 2, 'first val of device2'], ["device3", 3, 'first val of device3']])
df.pivot(index=1, columns=0, values=2).fillna(method='ffill').unstack().reset_index(name='value')
Result:
0 1 value
0 device1 1 first val of device1
1 device1 2 first val of device1
2 device1 3 first val of device1
3 device2 1 None
4 device2 2 first val of device2
5 device2 3 first val of device2
6 device3 1 None
7 device3 2 None
8 device3 3 first val of device3
For ES6/ES2015 you can import directly like:
// example.json
{
"name": "testing"
}
// ES6/ES2015
// app.js
import * as data from './example.json';
const {name} = data;
console.log(name); // output 'testing'
If you use Typescript, you may declare json module like:
// tying.d.ts
declare module "*.json" {
const value: any;
export default value;
}
Since Typescript 2.9+ you can add --resolveJsonModule compilerOptions in tsconfig.json
{
"compilerOptions": {
"target": "es5",
...
"resolveJsonModule": true,
...
},
...
}
Do you mean you want Class C to be the base class for A & B in that case.
public abstract class C
{
public abstract void Method1();
public abstract void Method2();
}
public class A : C
{
public override void Method1()
{
throw new NotImplementedException();
}
public override void Method2()
{
throw new NotImplementedException();
}
}
public class B : C
{
public override void Method1()
{
throw new NotImplementedException();
}
public override void Method2()
{
throw new NotImplementedException();
}
}
It worked well for me:
find directory_to_delete/ -type d -name '*.svn' | xargs rm -rf
import operator
a_list_of_dicts.sort(key=operator.itemgetter('name'))
'key' is used to sort by an arbitrary value and 'itemgetter' sets that value to each item's 'name' attribute.
Please check out my gist where I have made a category for UILabel
for something very similar, my category lets a UILabel
stretch it's height to show all the content: https://gist.github.com/1005520
Or check out this post: https://stackoverflow.com/a/7242981/662605
This would stretch the height, but you can change it around easily to work the other way and stretch the width with something like this, which is I believe what you want to do:
@implementation UILabel (dynamicSizeMeWidth)
- (void)resizeToStretch{
float width = [self expectedWidth];
CGRect newFrame = [self frame];
newFrame.size.width = width;
[self setFrame:newFrame];
}
- (float)expectedWidth{
[self setNumberOfLines:1];
CGSize maximumLabelSize = CGSizeMake(CGRectGetWidth(self.bounds), CGFLOAT_MAX);
CGSize expectedLabelSize = [[self text] sizeWithFont:[self font]
constrainedToSize:maximumLabelSize
lineBreakMode:[self lineBreakMode]];
return expectedLabelSize.width;
}
@end
You could more simply use the sizeToFit
method available from the UIView
class, but set the number of lines to 1 to be safe.
If you are using AutoLayout, then you have a built in solution. By setting the number of lines to 0, the framework will resize your label appropriately (adding more height) to fit your text.
sizeWithFont:
is deprecated so use sizeWithAttributes:
instead:
- (float)expectedWidth{
[self setNumberOfLines:1];
CGSize expectedLabelSize = [[self text] sizeWithAttributes:@{NSFontAttributeName:self.font}];
return expectedLabelSize.width;
}
Merging json objects is fairly straight forward but has a few edge cases when dealing with key collisions. The biggest issues have to do with one object having a value of a simple type and the other having a complex type (Array or Object). You have to decide how you want to implement that. Our choice when we implemented this for json passed to chef-solo was to merge Objects and use the first source Object's value in all other cases.
This was our solution:
from collections import Mapping
import json
original = json.loads(jsonStringA)
addition = json.loads(jsonStringB)
for key, value in addition.iteritems():
if key in original:
original_value = original[key]
if isinstance(value, Mapping) and isinstance(original_value, Mapping):
merge_dicts(original_value, value)
elif not (isinstance(value, Mapping) or
isinstance(original_value, Mapping)):
original[key] = value
else:
raise ValueError('Attempting to merge {} with value {}'.format(
key, original_value))
else:
original[key] = value
You could add another case after the first case to check for lists if you want to merge those as well, or for specific cases when special keys are encountered.
On macOS Mojave 10.14.4, you can also try Command ? + Q in a terminal.
Put the CSS files in public/stylesheets and then use:
<%= stylesheet_link_tag "filename" %>
to link to the stylesheet in your layouts or erb files in your views.
Similarly you put images in public/images and javascript files in public/javascripts.
Use this:
print("Program for calculating sum")
numbers=[1, 2, 3, 4, 5, 6, 7, 8]
sum=0
for number in numbers:
sum += number
print("Total Sum is: %d" %sum )
I used a variation of the above but instead of printing html I built a form and submitted it to the 3rd party url:
var mapForm = document.createElement("form");
mapForm.target = "Map";
mapForm.method = "POST"; // or "post" if appropriate
mapForm.action = "http://www.url.com/map.php";
var mapInput = document.createElement("input");
mapInput.type = "text";
mapInput.name = "addrs";
mapInput.value = data;
mapForm.appendChild(mapInput);
document.body.appendChild(mapForm);
map = window.open("", "Map", "status=0,title=0,height=600,width=800,scrollbars=1");
if (map) {
mapForm.submit();
} else {
alert('You must allow popups for this map to work.');
}
There is no way to retrieve localStorage, sessionStorage or cookie values via javascript in the browser after they've been deleted via javascript.
If what you're really asking is if there is some other way (from outside the browser) to recover that data, that's a different question and the answer will entirely depend upon the specific browser and how it implements the storage of each of those types of data.
For example, Firefox stores cookies as individual files. When a cookie is deleted, its file is deleted. That means that the cookie can no longer be accessed via the browser. But, we know that from outside the browser, using system tools, the contents of deleted files can sometimes be retrieved.
If you wanted to look into this further, you'd have to discover how each browser stores each data type on each platform of interest and then explore if that type of storage has any recovery strategy.
There are 3 ways I can think of:
The way that is easiest to explain is
:%s/phrase to delete//gc
but you can also (personally I use this second one more often) do a regular search for the phrase to delete
/phrase to delete
Vim will take you to the beginning of the next occurrence of the phrase.
Go into insert mode (hit i) and use the Delete key to remove the phrase.
Hit escape when you have deleted all of the phrase.
Now that you have done this one time, you can hit n to go to the next occurrence of the phrase and then hit the dot/period "." key to perform the delete action you just performed
Continue hitting n and dot until you are done.
Lastly you can do a search for the phrase to delete (like in second method) but this time, instead of going into insert mode, you
Count the number of characters you want to delete
Type that number in (with number keys)
Hit the x key - characters should get deleted
Continue through with n and dot like in the second method.
PS - And if you didn't know already you can do a capital n to move backwards through the search matches.
command_1 && command_2
: execute command_2 only when command_1 is executed successfully.
command_1 || command_2
: execute command_2 only when command_1 is not successful executed.
Feels similar as how an 'if' condition is executed in a mainstream programming language, like, in if (condition_1 && condition_2){...}
condition_2 will be omitted if condition_1 is false
and in if (condition_1 || condition_2){...}
condition_2 will be omitted if condition_1 is true
.
See, it's the same trick you use for coding :)
